PROSPECTUS SUMMARY

        The following summary highlights selected information contained in this prospectus. This summary does not contain all the information you should consider before investing in the securities. Before making an investment decision, you should read the entire prospectus carefully, including the "Risk Factors" section, the financial statements and the notes to the financial statements.

Overview of Business

        We are a biotechnology company focused on developing and commercializing human embryonic and adult stem cell technology in the emerging field of regenerative medicine. Our plan is to successfully develop and commercialize products for use in treatment of a wide array of chronic degenerative diseases and in regenerative repair of acute disease. Our research and development programs are focused on therapies utilizing both human embryonic stem cell technology and adult stem cell technology. We have completed preclinical testing, two multi-center Phase I safety studies and a Phase Ib study of our adult stem cell therapy product. All of our human embryonic stem cell technologies are at the basic research or in the pre-clinical stage of development.

        Our research and development is supported by our portfolio of patents and patent applications and a research and development team that includes some of the world's leading scientists in the field of stem cell research and development. We have four core categories of research and development programs:

Human Embryonic Stem Cell Programs

Adult Stem Cell Therapy Program

        The core of our human embryonic stem cell technology platform is the ability to produce embryonic stem cells that are immunologically compatible with the patient. If successfully developed, our cellular reprogramming technologies will produce cells that will maximize the potential for effective use as transplants to replace diseased or destroyed cells in human patients. Our technology avoids reliance on more limited approaches that involve use of cell lines that are not histocompatible with the recipient, or therapies based upon use of adult stem cells. We believe that successful commercialization of stem cell technologies will require the ability to produce cells that are immunologically compatible with the patient, have the proliferative capacity of young cells and have specific therapeutic application. Our research and development programs are dedicated to production of stem cell therapies that share these characteristics.

        The myoblast program is based upon a strong intellectual property portfolio and the successful completion of Phase I and Phase Ib clinical trials which demonstrated a "proof of concept" and the overall therapeutic promise of restoring function to damaged myocardium by myoblast transplantation. We intend to initiate a Phase II clinical trial in 2008 to serve as the foundation for FDA regulatory approval and ultimate product commercialization.

        We believe that successful development of our technologies could provide cell-based therapies for a broad range of diseases, including:

        Our headquarters are located at 1201 Harbor Bay Parkway, Alameda, California 94502. Our other research facilities are located in Worcester, Massachusetts and Charlestown, Massachusetts.

Recent Developments

        Recent Acquisition.    As disclosed in our Current Reports on Form 8-K filed with the Securities and Exchange Commission, or SEC, on July 31, 2007 and September 26, 2007, we entered into that certain Agreement and Plan of Merger, or merger agreement, with Mytogen, Inc., a Delaware corporation. On September 18, 2007, ACT Acquisition Sub, Inc., a wholly owned subsidiary of ours, closed on the acquisition of the previously announced Mytogen transaction pursuant to the terms of the merger agreement. As a result of the closing, all of the issued and outstanding shares of Mytogen were canceled, and certain equity holders of Mytogen received (i) shares of our common stock having an aggregate value of $5,000,000 based on a per share price of $0.62, and/or (ii) warrants to purchase an aggregate of 1,500,000 shares of our common stock at an exercise price of $0.75 per share. In connection with the closing, we assumed certain liabilities of Mytogen in the aggregate amount of approximately $1,737,000.

        Financing.    As disclosed in our Current Report on Form 8-K filed with the SEC on September 7, 2007, we closed on the issuance of $12,250,000 of its amortizing senior secured convertible debentures and associated warrants on August 31, 2007. This transaction is sometimes hereinafter referred to as the 2007 Financing. Proceeds resulting from the 2007 Financing were released from escrow on September 7, 2007. In connection with the closing of the 2007 Financing, we entered into a Securities Purchase Agreement, dated as of August 31, 2007, with the purchasers of the debentures. The purchasers purchased from us senior secured convertible debentures, or the 2007 Debentures, and warrants to purchase shares of our common stock, or the 2007 Warrants. We also entered into a Registration Rights Agreement with the purchasers, which requires that we file a registration statement with the SEC within 30 days after the closing of the 2007 Financing registering on behalf of the purchasers the resale of all or such maximum portion of the shares of common stock issuable upon conversion of the debentures and the exercise of the warrants, as permitted pursuant to Securities and

2



Exchange Commission guidance regarding offerings made on a continuous basis pursuant to SEC Rule 415.

        The amortizing senior secured convertible debentures issued at the closing of the 2007 Financing are due and payable in full three (3) years from the closing, and will not bear interest. The debentures begin amortizing on the earlier of (i) September 1, 2008, (ii) the first trading day of the month following the effective date of the initial Registration Statement filed pursuant to the Registration Rights Agreement, but in no event prior to February 1, 2008. The aggregate cash purchase price for the debentures purchased at the 2007 Financing was $10,000,000, which is a 20.3187% discount to the full principal amount of the debenture of $12,550,000. At any time from the closing date until the maturity date of the debentures, the purchasers have the right to convert the debentures, in whole or in part, into our common stock at the then effective conversion price. The debentures are initially convertible into 36,911,765 shares of common stock at a price of $0.34 per share. The conversion price shall be subject to adjustment under circumstances set forth in the debentures. The purchasers in the 2007 Financing also received warrants to purchase an aggregate of 36,911,765 additional shares of common stock at a price of $0.38 per share exercisable for five (5) years. Such warrants are sometimes hereinafter referred to as the 2007 Warrants.

        Our obligations to the purchasers in the 2007 Financing are secured by a senior security interest and lien granted upon all our assets pursuant to the terms of a Security Agreement entered into in connection with the closing. The security interest granted under the Security Agreement also secures our obligations to the holders of (i) the debentures in the existing 2005 financing, and (ii) the debentures in the existing 2006 financing. The debentures issued in the 2005 financing are sometimes hereinafter referred to as the 2005 Debentures and the debentues issued in the 2006 financing are sometimes hereinafter referred to as the 2006 Debentures. Inclusion of holders of the 2005 Debentures and the 2006 Debentures was a condition of obtaining from such holders the necessary consents to the 2007 Financing.

        The Securities Purchase Agreement, and the other agreements and instruments contemplated thereby including the debentures and the warrants, contain covenants that limit our ability to, among other things: incur or guarantee additional indebtedness; incur or create liens; amend our certificate of incorporation, bylaws or other charter documents so as to adversely affect any rights of the holders of the debentures; repay or repurchase more than a de minimis number of shares of common stock other than as permitted in the debentures and other documents executed with the purchasers and make cash expenditures in excess of $1,000,000 per calendar month, subject to certain specified exceptions. The 2007 Debentures include customary default provisions and an event of default includes, among other things, a change of control, the sale of all or substantially all our assets, the failure by us to have registration statements declared effective on or before the deadlines set forth in the Registration Rights Agreement, the lapse of the effectiveness of registration statements for more than 30 consecutive trading days or 60 non-consecutive days during any 12-month period (with certain exceptions), the failure to timely deliver certificates to holders upon conversion and a default by us in any obligations under any indebtedness of at least $100,000 which results in such indebtedness being accelerated. Upon the occurrence of an event of default, each 2007 Debenture may become immediately due and payable, either automatically or by declaration of the holder of such debenture. The aggregate amount payable upon an acceleration by reason of an event of default shall be equal to the greater of 120% of the principal amount of the debentures to be prepaid or the principal amount of the debentures to be prepaid, divided by the conversion price on the date specified in the debenture, multiplied by the closing price on the date set forth in the debenture.

        In connection with this transaction, each purchaser has contractually agreed to restrict its ability to convert the debentures, exercise the warrants and additional investment rights and receive shares of our common stock such that the number of shares of our common stock held by each such purchaser and

3


its affiliates after such conversion or exercise does not exceed 4.99% of the number of shares of our common stock outstanding immediately after giving effect to such conversion or exercise.

        Certain of our officers have entered into a lock-up agreement that restricts their right to dispose of any shares of our common stock for a period of one year following the effective date of a registration statement registering the shares of our common stock as provided in the Registration Rights Agreement.

        All of the above securities were issued pursuant to an exemption from registration pursuant to Section 4(2) of the Securities Act of 1933.

Risk Factors

        Investing in our common stock is subject to numerous risks, including the risk of delays in or discontinuation of our research and development due to lack of financing, inability to obtain necessary regulatory approvals to market the products, unforeseen safety issues relating to the products and dependence on third party collaborators to conduct research and development of the products. Because we are an early stage company with a very limited history of operations, we are also subject to many risks associated with early-stage companies. For a more detailed discussion of some of the risks you should consider before purchasing shares of our common stock, you are urged to carefully review and consider the section entitled "Risk Factors" beginning on page 6 of this prospectus.

Corporate History

        We were incorporated under Nevada law in May of 2000. On January 31, 2005, we completed an acquisition of Advanced Cell, Inc., a Delaware corporation, formerly known as Advanced Cell Technology, Inc. and referred to as ACT, pursuant to the terms of an agreement and plan of merger dated January 3, 2005. At the time of the transaction, we had only nominal assets and no operating activities. Pursuant to the terms of the merger, a wholly owned subsidiary of ours merged with and into ACT, with ACT surviving the merger as our wholly owned subsidiary. As a result of the merger, all of the outstanding shares of the capital stock of ACT were converted, on a pro rata basis, into the right to receive an aggregate of approximately 18,000,000 shares of our common stock. In addition, all outstanding options and warrants to acquire shares of the capital stock of ACT were converted into the right to receive shares of our common stock, and we adopted the ACT stock option plan and all options granted thereunder. Upon completion of the merger, all of our pre-merger officers and directors resigned and were replaced by ACT's officers and directors. As a result of the merger, we effected a complete change of business operations and terminated our pre-merger business and succeeded to, and are continuing the business operations and research efforts of, ACT in the field of biotechnology.

        On November 18, 2005, as described above, we reincorporated the company from the State of Nevada to the State of Delaware pursuant to a merger of the company with and into a newly formed Delaware corporation. Immediately following the reincorporation, we completed the merger of ACT with and into the company, so that the separate existence of ACT has ceased.

        In connection with the previously described acquisition of Mytogen, we formed a wholly-owned subsidiary, ACT Acquisition Sub, Inc., which merged with and into Mytogen, so that the separate existence of ACT Acquisition Sub, Inc. has ceased and Mytogen survived the merger as our wholly-owned subsidiary.

        Our principal executive offices are located at 1201 Harbor Bay Parkway, Alameda, California 94502, and our telephone number is (510) 748-4900.

RISK FACTORS

        You should carefully consider each of the following risk factors and all of the other information provided in this prospectus before purchasing our common stock. The risks described below are those we currently believe may materially affect us. An investment in our common stock involves a high degree of risk, and should be considered only by persons who can afford the loss of their entire investment. This prospectus contains forward-looking statements that involve risks and uncertainties. We use words such as "may," "assumes," "forecasts," "positions," "predicts," "strategy," "will," "expects," "estimates," "anticipates," "believes," "projects," "intends," "plans," "budgets," "potential," "continue" and variations thereof, and other statements contained in quarterly report, and the exhibits hereto, regarding matters that are not historical facts and are forward-looking statements. Because these statements involve risks and uncertainties, as well as certain assumptions, actual results may differ materially from those expressed or implied by such forward-looking statements. Factors that could cause actual results to differ materially include, but are not limited to risks inherent in: our early stage of development, including a lack of operating history, lack of profitable operations and the need for additional capital; the development and commercialization of largely novel and unproven technologies and products; our ability to protect, maintain, and defend our intellectual property rights: uncertainties regarding our ability to obtain the capital resources needed to continue research and development operations and to conduct research, preclinical development and clinical trials necessary for regulatory approvals; uncertainty regarding the outcome of clinical trials and our overall ability to compete effectively in a highly complex, rapidly developing, capital intensive and competitive industry.

Risks Relating to Our Early Stage of Development

        We have a limited operating history on which potential investors may evaluate our operations and prospects for profitable operations.    We have a limited operating history on which a potential investor may base an evaluation of us and our prospects. If we are unable to begin and sustain profitable operations, investors may lose their entire investment in us. Our human embryonic stem cell programs are in the pre-clinical stage, and our adult stem cell myoblast program has completed Phase I and Ib Food and Drug Administration, or FDA, clinical trials. Our prospects must be considered speculative in light of the risks, expenses and difficulties frequently encountered by companies in their early stages of development, particularly in light of the uncertainties relating to the new, competitive and rapidly evolving markets in which we anticipate we will operate. To attempt to address these risks, we must, among other things, further develop our technologies, products and services, successfully implement our research, development, marketing and commercialization strategies, respond to competitive developments and attract, retain and motivate qualified personnel. A substantial risk is involved in investing in us because, as an early stage company,

        These difficulties are compounded by our heavy dependence on emerging and sometimes unproven technologies. In addition, some of our significant potential revenue sources involve ethically sensitive and controversial issues which could become the subject of legislation or regulations that could materially restrict our operations and, therefore, harm our financial condition, operating results and prospects for bringing our investors a return on their investment.

        We have a history of operating losses, and we cannot assure you that we will achieve future revenues or operating profits.    We have generated modest revenue to date from our operations. Historically, we have had net operating losses each year since our inception. We have limited current potential sources of revenue from license fees and product development revenues, and we cannot

6



assure you that we will be able to develop such revenue sources or that our operations will become profitable, even if we are able to commercialize our technologies or any products or services developed from those technologies. If we continue to suffer losses as we have in the past, investors may not receive any return on their investment and may lose their entire investment.

        Although we have revenues from license fees and royalties, we have no commercially marketable products and no immediate ability to generate revenue from commercial products, nor any assurance of being able to develop our technologies for commercial applications. As a result, we may never be able to operate profitably. We are just beginning to identify products available for pre-clinical trials and may not receive significant revenues from commercial sales of our products for the next several years, if at all, although we do generate revenues from licensing activities. We have marketed only a limited amount of services based on our technologies and have little experience in doing so. Our technologies and any potential products or services that we may develop will require significant additional effort and investment prior to material commercialization and, in the case of any biomedical products, pre-clinical and clinical testing and regulatory approvals. We cannot assure you that we will be able to develop any such technologies or any products or services, or that such technologies, products or services will prove to be safe and efficacious in clinical trials, meet applicable regulatory standards, be capable of being produced in commercial quantities at acceptable costs or be successfully marketed. For that reason, we may not be able to generate revenues from commercial production or operate profitably.

        We have sold the agricultural portion of our business in order to finance operations. The agricultural applications of our technology generally have a more rapid realization of revenues due to more limited regulatory requirements and testing. Our ability to generate revenue from any agricultural applications of our technology is limited to existing license royalties, if any.

        We will require substantial additional funds to continue operating which may not be available on acceptable terms, if at all.    We have losses from operations, negative cash flows from operations and a substantial stockholders' deficit that raise substantial doubt about our ability to continue as a going concern. We do not believe that our cash from all sources, including cash, cash equivalents and anticipated revenue stream from licensing fees and sponsored research contracts is sufficient for us to continue operations beyond June 30, 2008 without raising additional financing.

        Management continues to evaluate alternatives and sources for additional funding, which may include public or private investors, strategic partners, and grant programs available through specific states or foundations, although there is no assurance that such sources will result in raising additional capital. Lack of necessary funds may require us to delay, scale back or eliminate some or all of our research and product development programs and/or our capital expenditures, to license our potential products or technologies to third parties, to consider business combinations related to ongoing business operations, or shut down some, or all, of our operations.

        In addition, our cash requirements may vary materially from those now planned because of results of research and development, potential relationships with strategic partners, changes in the focus and direction of our research and development programs, competition, litigation required to protect our technology, technological advances, the cost of pre-clinical and clinical testing, the regulatory process of the FDA, and foreign regulators, whether any of our products become approved or the market acceptance of any such products and other factors. Our current cash reserves are not sufficient to fund our operations through the commercialization of our first products or services.

        We have limited clinical testing, regulatory, manufacturing, marketing, distribution and sales capabilities which may limit our ability to generate revenues.    Because of the relatively early stage of our research and development programs, we have not yet invested significantly in regulatory, manufacturing, marketing, distribution or product sales resources. We cannot assure you that we will be able to develop any such resources successfully or as quickly as may be necessary. The inability to do so may harm our ability to generate revenues or operate profitably.

Risks Relating to Competition

        Our competition includes both public and private organizations and collaborations among academic institutions and large pharmaceutical companies, most of which have significantly greater experience and financial resources than we do.    The biotechnology and pharmaceutical industries are characterized by intense competition. We compete against numerous companies, both domestic and foreign, many of which have substantially greater experience and financial and other resources than we have. Several such enterprises have initiated cell therapy research programs and/or efforts to treat the same diseases targeted by us. Companies such as Geron Corporation, Genzyme Corporation, StemCells, Inc., Aastrom Biosciences, Inc. and Viacell, Inc., as well as others, many of which have substantially greater resources and experience in our fields than we do, are well situated to effectively compete with us. Any of the world's largest pharmaceutical companies represents a significant actual or potential competitor with vastly greater resources than ours.

        These companies hold licenses to genetic selection technologies and other technologies that are competitive with our technologies. These and other competitive enterprises have devoted, and will continue to devote, substantial resources to the development of technologies and products in competition with us.

        Private and public academic and research institutions also compete with us in the research and development of therapeutic products based on human embryonic and adult stem cell technologies. In the past several years, the pharmaceutical industry has selectively entered into collaborations with both public and private organizations to explore the possibilities that stem cell therapies may present for substantive breakthroughs in the fight against disease.

        In addition, many of our competitors have significantly greater experience than we have in the development, pre-clinical testing and human clinical trials of biotechnology and pharmaceutical products, in obtaining FDA and other regulatory approvals of such products and in manufacturing and marketing such products. Accordingly our competitors may succeed in obtaining FDA approval for products more rapidly or effectively than we can. Our competitors may also be the first to discover and obtain a valid patent to a particular stem cell technology which may effectively block all others from doing so. It will be important for us or our collaborators to be the first to discover any stem cell technology that we are seeking to discover. Failure to be the first could prevent us from commercializing all of our research and development affected by that discovery. Additionally, if we commence commercial sales of any products, we will also be competing with respect to manufacturing efficiency and sales and marketing capabilities, areas in which we have no experience.

        The United States is encountering tremendous competition from many foreign countries that are providing an environment more attractive for stem cell research. The governments of numerous foreign countries are investing in stem cell research, providing facilities, personnel and legal environments intended to attract biotechnology companies and encourage stem cell research and development of stem cell-related technologies.

        These efforts by foreign countries may make it more difficult to effectively compete in our industry and may generate competitors with substantially greater resources than ours.

Risks Relating to Our Technology

        We rely on nuclear transfer and embryonic stem cell technologies that we may not be able to successfully develop, which will prevent us from generating revenues, operating profitably or providing investors any return on their investment.    We have concentrated our research on our nuclear transfer, embryonic stem cell and myoblast technologies, and our ability to operate profitably will depend on being able to successfully develop these technologies for human applications. These are emerging technologies with, as yet, limited human applications. We cannot guarantee that we will be able to successfully develop our nuclear transfer, embryonic stem cell or myoblast technologies or that such

8


development will result in products or services with any significant commercial utility. We anticipate that the commercial sale of such products or services, and royalty/licensing fees related to our technology, would be our primary sources of revenues. If we are unable to develop our technologies, investors will likely lose their entire investment in us.

        The outcome of pre-clinical, clinical and product testing of our products is uncertain, and if we are unable to satisfactorily complete such testing, or if such testing yields unsatisfactory results, we will be unable to commercially produce our proposed products. Before obtaining regulatory approvals for the commercial sale of any potential human products, our products will be subjected to extensive pre-clinical and clinical testing to demonstrate their safety and efficacy in humans. We cannot assure you that the clinical trials of our products, or those of our licensees or collaborators, will demonstrate the safety and efficacy of such products at all, or to the extent necessary to obtain appropriate regulatory approvals, or that the testing of such products will be completed in a timely manner, if at all, or without significant increases in costs, program delays or both, all of which could harm our ability to generate revenues. In addition, our prospective products may not prove to be more effective for treating disease or injury than current therapies. Accordingly, we may have to delay or abandon efforts to research, develop or obtain regulatory approval to market our prospective products. Many companies involved in biotechnology research and development have suffered significant setbacks in advanced clinical trials, even after promising results in earlier trials. The failure to adequately demonstrate the safety and efficacy of a therapeutic product under development could delay or prevent regulatory approval of the product and could harm our ability to generate revenues, operate profitably or produce any return on an investment in us.

        While the marketing of cloned or transgenic animals does not currently require regulatory approval, such approval may be required in the future. We cannot assure you that we would obtain such approvals or that our licensees' products would be accepted in the marketplace. This lack of approval could reduce or preclude any royalty revenues we might receive from our licensees in that field.

        We may not be able to commercially develop our technologies and proposed product lines, which, in turn, would significantly harm our ability to earn revenues and result in a loss of investment.    Our ability to commercially develop our technologies will be dictated in large part by forces outside our control which cannot be predicted, including, but not limited to, general economic conditions, the success of our research and pre-clinical and field testing, the availability of collaborative partners to finance our work in pursuing applications of nuclear transfer technology and technological or other developments in the biomedical field which, due to efficiencies, technological breakthroughs or greater acceptance in the biomedical industry, may render one or more areas of commercialization more attractive, obsolete or competitively unattractive. It is possible that one or more areas of commercialization will not be pursued at all if a collaborative partner or entity willing to fund research and development cannot be located. Our decisions regarding the ultimate products and/or services we pursue could have a significant adverse affect on our ability to earn revenue if we misinterpret trends, underestimate development costs and/or pursue wrong products or services. Any of these factors either alone or in concert could materially harm our ability to earn revenues and could result in a loss of any investment in us.

        If we are unable to keep up with rapid technological changes in our field or compete effectively, we will be unable to operate profitably.    We are engaged in activities in the biotechnology field, which is characterized by extensive research efforts and rapid technological progress. If we fail to anticipate or respond adequately to technological developments, our ability to operate profitably could suffer. We cannot assure you that research and discoveries by other biotechnology, agricultural, pharmaceutical or other companies will not render our technologies or potential products or services uneconomical or result in products superior to those we develop or that any technologies, products or services we develop will be preferred to any existing or newly-developed technologies, products or services.

9



        We may not be able to protect our proprietary technology, which could harm our ability to operate profitably.    The biotechnology and pharmaceutical industries place considerable importance on obtaining patent and trade secret protection for new technologies, products and processes. Our success will depend, to a substantial degree, on our ability to obtain and enforce patent protection for our products, preserve any trade secrets and operate without infringing the proprietary rights of others. We cannot assure you that:

        We are aware of certain patents that have been granted to others and certain patent applications that have been filed by others with respect to nuclear transfer technologies. The fields in which we operate have been characterized by significant efforts by competitors to establish dominant or blocking patent rights to gain a competitive advantage, and by considerable differences of opinion as to the value and legal legitimacy of competitors' purported patent rights and the technologies they actually utilize in their businesses.

        Our business is highly dependent upon maintaining licenses with respect to key technology.    Several of the key patents we utilize are licensed to us by third parties. These licenses are subject to termination under certain circumstances (including, for example, our failure to make minimum royalty payments or to timely achieve development and commercialization benchmarks). The loss of any of such licenses, or the conversion of such licenses to non-exclusive licenses, could harm our operations and/or enhance the prospects of our competitors.

        Certain of these licenses also contain restrictions, such as limitations on our ability to grant sublicenses that could materially interfere with our ability to generate revenue through the licensing or sale to third parties of important and valuable technologies that we have, for strategic reasons, elected not to pursue directly. The possibility exists that in the future we will require further licenses to complete and/or commercialize our proposed products. We cannot assure you that we will be able to acquire any such licenses on a commercially viable basis.

        We may not be able to adequately protect against piracy of intellectual property in foreign jurisdictions.    Considerable research in the areas of stem cells, cell therapeutics and regenerative medicine is being performed in countries outside of the United States, and a number of our competitors are located in those countries. The laws protecting intellectual property in some of those countries may not provide protection for our trade secrets and intellectual property adequate to prevent our competitors from misappropriating our trade secrets or intellectual property. If our trade secrets or intellectual property are misappropriated in those countries, we may be without adequate remedies to address the issue.

        Certain of our technology is not protectable by patent.    Certain parts of our know-how and technology are not patentable. To protect our proprietary position in such know-how and technology, we intend to require all employees, consultants, advisors and collaborators to enter into confidentiality and invention ownership agreements with us. We cannot assure you, however, that these agreements will provide meaningful protection for our trade secrets, know-how or other proprietary information in

10



the event of any unauthorized use or disclosure. Further, in the absence of patent protection, competitors who independently develop substantially equivalent technology may harm our business.

        Patent litigation presents an ongoing threat to our business with respect to both outcomes and costs.    We have previously been involved in patent interference litigation, and it is possible that further litigation over patent matters with one or more competitors could arise. We could incur substantial litigation or interference costs in defending ourselves against suits brought against us or in suits in which we may assert our patents against others. If the outcome of any such litigation is unfavorable, our business could be materially adversely affected. To determine the priority of inventions, we may also have to participate in interference proceedings declared by the United States Patent and Trademark Office, which could result in substantial cost to us. Without additional capital, we may not have the resources to adequately defend or pursue this litigation.

Risks Related to Product Development

        Limited experience in conducting and managing preclinical development activities, clinical trials and the application process necessary to obtain regulatory approvals.    Our limited experience in conducting and managing preclinical development activities, clinical trials and the application process necessary to obtain regulatory approvals might prevent us from successfully designing or implementing a preclinical study or clinical trial. If we do not succeed in conducting and managing our preclinical development activities or clinical trials, or in obtaining regulatory approvals, we might not be able to commercialize our product candidates, or might be significantly delayed in doing so, which will materially harm our business.

        None of the products that we are currently developing has been approved by the FDA or any similar regulatory authority in any foreign country. Our ability to generate revenues from any of our product candidates will depend on a number of factors, including our ability to successfully complete clinical trials, obtain necessary regulatory approvals and implement our commercialization strategy. In addition, even if we are successful in obtaining necessary regulatory approvals and bringing one or more product candidates to market, we will be subject to the risk that the marketplace will not accept those products. We may, and anticipate that we will need to, transition from a company with a research and development focus to a company capable of supporting commercial activities and we may not succeed in such a transition.

        Because of the numerous risks and uncertainties associated with our product development and commercialization efforts, we are unable to predict the extent of our future losses or when or if we will become profitable. Our failure to successfully commercialize our product candidates or to become and remain profitable could depress the market price of our common stock and impair our ability to raise capital, expand our business, diversify our product offerings and continue our operations.

        Our approach of using cell-based therapy for the treatment of heart damage is risky and unproven and no products using this approach have received regulatory approval in the United States or Europe.    We believe that no company has yet been successful in its efforts to obtain regulatory approval in the United States or Europe of a cell-based therapy product for the treatment of heart disease in humans. Cell-based therapy products, in general, may be susceptible to various risks, including undesirable and unintended side effects, unintended immune system responses, inadequate therapeutic efficacy or other characteristics that may prevent or limit their approval by regulators or commercial use. Many companies in the industry have suffered significant setbacks in advanced clinical trials, despite promising results in earlier trials.

        If our clinical trials are unsuccessful or significantly delayed, or if we do not complete our clinical trials, we will not receive regulatory approval for or be able to commercialize our product candidates.    Our lead product candidate, our myoblast program, is still in clinical testing and has not yet received approval from the FDA or any similar foreign regulatory authority for any indication. Although this

11



product candidate has received positive results in Phase I and Ib clinical trials, it may never receive regulatory approval or be commercialized in the United States or other countries.

        We cannot market any product candidate until regulatory agencies grant approval or licensure. In order to obtain regulatory approval for the sale of any product candidate, we must, among other requirements, provide the FDA and similar foreign regulatory authorities with preclinical and clinical data that demonstrate to the satisfaction of regulatory authorities that our product candidates are safe and effective for each indication under the applicable standards relating to such product candidate. The preclinical studies and clinical trials of any product candidates must comply with the regulations of the FDA and other governmental authorities in the United States and similar agencies in other countries.

        Even though we have achieved positive interim results in clinical trials, these results do not necessarily predict final results, and positive results in early trials may not be indicative of success in later trials. For example, our myoblast program has been studied in a limited number of patients to date. Even though our early data has been promising, we have not yet completed any large-scale pivotal trials to establish the safety and efficacy of this therapy. There is a risk that safety concerns relating to our product candidates or cell-based therapies in general will result in the suspension or termination of our clinical trials.

        We may experience numerous unforeseen events during, or as a result of, the clinical trial process that could delay or prevent regulatory approval and/or commercialization of our product candidates, including the following:

12


        We depend on third parties to assist us in the conduct of our preclinical studies and clinical trials, and any failure of those parties to fulfill their obligations could result in costs and delays and prevent us from obtaining regulatory approval or successfully commercializing our product candidates on a timely basis, if at all.    We engage consultants and contract research organizations to help design, and to assist us in conducting, our preclinical studies and clinical trials and to collect and analyze data from those studies and trials. The consultants and contract research organizations we engage interact with clinical investigators to enroll patients in our clinical trials. As a result, we depend on these consultants and contract research organizations to perform the studies and trials in accordance with the investigational plan and protocol for each product candidate and in compliance with regulations and standards, commonly referred to as "good clinical practice", for conducting, recording and reporting results of clinical trials to assure that the data and results are credible and accurate and the trial participants are adequately protected, as required by the FDA and foreign regulatory agencies. We may face delays in our regulatory approval process if these parties do not perform their obligations in a timely or competent fashion or if we are forced to change service providers.

        We must comply with extensive government regulations in order to obtain and maintain marketing approval for our products in the United States and abroad. If we do not obtain regulatory approval for our product candidates, we may be forced to cease our operations.    Our product candidates are subject to extensive regulation in the United States and in every other country where they will be tested or used. These regulations are wide-ranging and govern, among other things:

        We cannot market our product candidates until we receive regulatory approval. The process of obtaining regulatory approval is lengthy, expensive and uncertain. Any difficulties that we encounter in obtaining regulatory approval may have a substantial adverse impact on our business and cause our stock price to significantly decline.

        In the United States, the FDA imposes substantial requirements on the introduction of biological products and many medical devices through lengthy and detailed laboratory and clinical testing procedures, sampling activities and other costly and time-consuming procedures. Satisfaction of these requirements typically takes several years and the time required to do so may vary substantially based upon the type and complexity of the biological product or medical device.

        In addition, product candidates that we believe should be classified as medical devices for purposes of the FDA regulatory pathway may be determined by the FDA to be biologic products subject to the satisfaction of significantly more stringent requirements for FDA approval.

        The requirements governing the conduct of clinical trials and cell culturing and marketing of our product candidates outside the United States vary widely from country to country. Foreign approvals may take longer to obtain than FDA approvals and can require, among other things, additional testing and different clinical trial designs. Foreign regulatory approval processes generally include all of the risks associated with the FDA approval processes. Some foreign regulatory agencies also must approve

13



prices of the products. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may negatively impact the regulatory process in others. We may not be able to file for regulatory approvals and may not receive necessary approvals to market our product candidates in any foreign country. If we fail to comply with these regulatory requirements or fail to obtain and maintain required approvals in any foreign country, we will not be able to sell our product candidates in that country and our ability to generate revenue will be adversely affected.

        We cannot assure you that we will obtain FDA or foreign regulatory approval to market any of our product candidates for any indication in a timely manner or at all. If we fail to obtain regulatory approval of any of our product candidates for at least one indication, we will not be permitted to market our product candidates and may be forced to cease our operations.

        Even if some of our product candidates receive regulatory approval, these approvals may be subject to conditions, and we and our third party manufacturers will in any event be subject to significant ongoing regulatory obligations and oversight.    Even if any of our product candidates receives regulatory approval, the manufacturing, marketing and sale of our product candidates will be subject to stringent and ongoing government regulation. Conditions of approval, such as limiting the category of patients who can use the product, may significantly impact our ability to commercialize the product and may make it difficult or impossible for us to market a product profitably. Changes we may desire to make to an approved product, such as cell culturing changes or revised labeling, may require further regulatory review and approval, which could prevent us from updating or otherwise changing an approved product. If our product candidates are approved by the FDA or other regulatory authorities for the treatment of any indications, regulatory labeling may specify that our product candidates be used in conjunction with other therapies.

        Once obtained, regulatory approvals may be withdrawn for a number of reasons, including the later discovery of previously unknown problems with the product. Regulatory approval may also require costly post-marketing follow-up studies, and failure of our product candidates to demonstrate sufficient efficacy and safety in these studies may result in either withdrawal of marketing approval or severe limitations on permitted product usage. In addition, numerous additional regulatory requirements relating to, among other processes, the labeling, packaging, adverse event reporting, storage, advertising, promotion and record-keeping will also apply. Furthermore, regulatory agencies subject a marketed product, its manufacturer and the manufacturer's facilities to continual review and periodic inspections. Compliance with these regulatory requirements are time consuming and require the expenditure of substantial resources.

        If any of our product candidates is approved, we will be required to report certain adverse events involving our products to the FDA, to provide updated safety and efficacy information and to comply with requirements concerning the advertisement and promotional labeling of our products. As a result, even if we obtain necessary regulatory approvals to market our product candidates for any indication, any adverse results, circumstances or events that are subsequently discovered, could require that we cease marketing the product for that indication or expend money, time and effort to ensure full compliance, which could have a material adverse effect on our business.

        Any failure by us, or by any third parties that may manufacture or market our products, to comply with the law, including statutes and regulations administered by the FDA or other U.S. or foreign regulatory authorities, could result in, among other things, warning letters, fines and other civil penalties, suspension of regulatory approvals and the resulting requirement that we suspend sales of our products, refusal to approve pending applications or supplements to approved applications, export or import restrictions, interruption of production, operating restrictions, closure of the facilities used by us or third parties to manufacture our product candidates, injunctions or criminal prosecution. Any of the foregoing actions could have a material adverse effect on our business.

14



        The healthcare community has relatively little experience with therapies based on cellular medicine and, accordingly, if our product candidates do not become widely accepted by physicians, patients, third party payors or the healthcare community, we may be unable to generate significant revenue, if any.

        We are developing cell-based therapy product candidates for the treatment of heart damage that represent novel and unproven treatments and, if approved, will compete with a number of more conventional products and therapies manufactured and marketed by others, including major pharmaceutical companies. We cannot predict or guarantee that physicians, patients, healthcare insurers, third party payors or health maintenance organizations, or the healthcare community in general, will accept or utilize any of our product candidates. We anticipate that, if approved, we will market our myoblast product primarily to interventional cardiologists, who are generally not the primary care physicians for patients who may be eligible for treatment with MyoCell. Accordingly, our commercial success may be dependent on third party physicians referring their patients to interventional cardiologists for MyoCell treatment.

        If we are successful in obtaining regulatory approval for any of our product candidates, the degree of market acceptance of those products will depend on many factors, including:    


        Failure to achieve market acceptance would limit our ability to generate revenue and would have a material adverse effect on our business. In addition, if any of our product candidates achieve market acceptance, we may not be able to maintain that market acceptance over time if competing products or technologies are introduced that are received more favorably or are more cost-effective.

Risks Relating to the September 2005, September 2006, and August 2007 Financings

        If we are required for any reason to repay our outstanding debentures we would be required to deplete our working capital, if available, or raise additional funds. Our failure to repay the convertible debentures, if required, could result in legal action against us, which could require the sale of substantial assets.    We have outstanding, as of September 1, 2007, $23,479,420 aggregate original principal amount of convertible debentures with an original issue discount of 20.3187% with $12,550,000 in 2007 Debentures, $8,259,767 in 2006 Debentures, and $2,669,653 in 2005 Debentures.

15


We are required to redeem on a monthly basis, by payment, at our option, with cash or with shares of our common stock, 1/30th of the aggregate original principal amount of the debentures.

        The 2005 Debentures are due and payable on September 14, 2008, unless sooner converted into shares of our common stock, the 2006 Debentures are due and payable on February 28, 2010, and the 2007 Debentures are due and payable on August 31, 2010, unless sooner converted into shares of our common stock. Any event of default could require the early repayment of the convertible debentures, including the accruing of interest on the outstanding principal balance of the debentures if the default is not cured with the specified grace period. We anticipate that the full amount of the convertible debentures will be converted into shares of our common stock, in accordance with the terms of the convertible debentures; however no assurance can be provided that any amount of debentures will be converted. If, prior to the maturity date, we are required to repay the convertible debentures in full, we would be required to use our limited working capital and raise additional funds. If we were unable to repay the notes when required, the debenture holders could commence legal action against us to recover the amounts due. Any such action could require us to curtail or cease operations.

        There are a large number of shares underlying our convertible debentures in full, and warrants that are registered and available for sale and the sale of these shares may depress the market price of our common stock.    As of September 1, 2007, we had:

        Sales of a substantial number of shares of our common stock in the public market could adversely affect the market price for our common stock and make it more difficult for you to sell shares of our common stock at times and prices that you feel are appropriate.

        The issuance of shares upon conversion of the convertible debentures and exercise of outstanding warrants will cause immediate and substantial dilution to our existing stockholders.    The issuance of shares upon conversion of the convertible debentures and exercise of warrants, including the replacement warrants, will result in substantial dilution to the interests of other stockholders since the selling security holders may ultimately convert and sell the full amount issuable on conversion. Although no single selling security holder may convert its convertible debentures and/or exercise its warrants if such conversion or exercise would cause it to own more than 4.99% of our outstanding common stock, this restriction does not prevent each selling security holder from converting and/or exercising some of its holdings and then converting the rest of its holdings. In this way, each selling security holder could sell more than this limit while never holding more than this limit. There is no upper limit on the number of shares that may be issued which will have the effect of further diluting

16



the proportionate equity interest and voting power of holders of our common stock, including investors in this offering. In addition, the issuance of the 2007 Debentures and the 2007 Warrants triggered certain anti-dilution rights for certain third parties currently holding our securities resulting in substantial dilution to the interests of other stockholders.

        Payment of mandatory monthly redemptions in shares of common stock will result in substantial dilution.    We expect to satisfy all or a significant portion of our obligation to redeem 1/30th of the aggregate original principal amount of debentures per month through issuance of additional shares of our common stock. This approach will result in substantial dilution to the interests of other stockholders. In addition, many of our outstanding securities contain anti-dilution protections that will result in further dilution in the event the redemption prices associated with the monthly redemptions are below $.25 per share of our common stock.

        If we fail to effect and maintain registration of the common stock issued or issuable pursuant to conversion of our debentures, or upon exercise of our warrants, we may be obligated to pay the investors of those securities liquidated damages.    We have various obligations to file and obtain the effectiveness of certain registration statements which include certain outstanding common stock and common stock underlying outstanding debentures and common stock underlying the warrants. If we fail to meet any obligations we have to have effective and current registration statements available (including the current registration statement related to the common stock underlying our debentures and warrants), we may become obligated to pay liquidated damages to investors to the extent they may be entitled to such damages. In addition, to the filing of registration statements in connection with the 2007 Financing pursuant to the amendments to the 2005 and 2006 financing documents described above, we are contractually obligated to file additional registration statements at various times in the future. Because of the SEC's recent interpretation of Rule 415, we cannot offer any assurances that we will be able to obtain the effectiveness of any registration statement or post-effective amendments that we may file.

        Our outstanding indebtedness on our 2005, 2006 and 2007 Debentures imposes certain restrictions on how we conduct our business. In addition, all of our assets, including our intellectual property, are pledged to secure this indebtedness. If we fail to meet our obligations under the Debentures, our payment obligations may be accelerated and the collateral securing the debt may be sold to satisfy these obligations.

        The Debentures and related agreements contain various provisions that restrict our operating flexibility. Pursuant to the agreement, we may not, among other things:

17


These provisions could have important consequences for us, including (i) making it more difficult for us to obtain additional debt financing from another lender, or obtain new debt financing on terms favorable to us, (ii) causing us to use a portion of our available cash for debt repayment and service rather than other perceived needs and/or (iii) impacting our ability to take advantage of significant, perceived business opportunities.

        Our obligations under the Securities Purchase Agreement are secured by substantially all of our assets.    Our obligations under the security agreement, executed in connection with the 2007 Financing, with the holders of the debentures and warrants are secured by substantially all of our assets. As a result, if we default under the terms of the security agreement, such holders could foreclose on their security interest and liquidate all of our assets. This would cause operations to cease.

Risks Relating to Government Regulation

        Companies such as ours engaged in research using nuclear transfer and embryonic stem cells are currently subject to strict government regulations, and our operations could be harmed by any legislative or administrative efforts impacting the use of nuclear transfer technology or human embryonic material.    Our business is focused on human cell therapy, which includes the production of human differentiated cells from stem cells and involves the use of nuclear transfer technology, human oocytes, and embryonic material as well as adult stem cells. Nuclear transfer technology, commonly known as therapeutic cloning, and research utilizing embryonic stem cells are controversial subjects, and are currently subject to intense scrutiny, both in the United States, the United Nations and throughout the world, particularly in the area of nuclear transfer of human cells and the use of human embryonic material.

        We cannot assure you that our operations will not be harmed by any legislative or administrative efforts by politicians or groups opposed to the development of nuclear transfer technology generally or the use of nuclear transfer for therapeutic cloning of human cells specifically. Further, we cannot assure you that legislative or administrative restrictions directly or indirectly delaying, limiting or preventing the use of nuclear transfer technology or human embryonic material or the sale, manufacture or use of products or services derived from nuclear transfer technology or human embryonic material will not be adopted in the future.

18


        Restrictions on the use of human embryonic stem cells, and the ethical, legal and social implications of that research, could prevent us from developing or gaining acceptance for commercially viable products in these areas.    Some of our most important programs involve the use of stem cells that are derived from human embryos. The use of human embryonic stem cells gives rise to ethical, legal and social issues regarding the appropriate use of these cells. In the event that our research related to human embryonic stem cells becomes the subject of adverse commentary or publicity, the market price for our common stock could be significantly harmed. Some political and religious groups have voiced opposition to our technology and practices. We use stem cells derived from human embryos that have been created for in vitro fertilization procedures but are no longer desired or suitable for that use and are donated with appropriate informed consent for research use. Many research institutions, including some of our scientific collaborators, have adopted policies regarding the ethical use of human embryonic tissue. These policies may have the effect of limiting the scope of research conducted using human embryonic stem cells, thereby impairing our ability to conduct research in this field.

        Potential and actual legislation and regulation at the federal or state level related to our technology could limit our activities and ability to develop products for commercial sales, depriving us of our anticipated source of future revenues. Legislative bills could be introduced in the future aiming to prohibit the use or commercialization of somatic cell nuclear transfer technology or of any products resulting from it, including those related to human therapeutic cloning and regenerative medicine. Such legislation could have a significant influence on our ability to pursue our research, development and commercialization plans in the United States.

        Any future or additional government-imposed restrictions in these or other jurisdictions with respect to use of embryos or human embryonic stem cells in research and development could have a material adverse effect on us, by, among other things:

        Because we or our collaborators must obtain regulatory approval to market our products in the United States and other countries, we cannot predict whether or when we will be permitted to commercialize our products.    Federal, state and local governments in the United States and governments in other countries have significant regulations in place that govern many of our activities. We are or may become subject to various federal, state and local laws, regulations and recommendations relating to safe working conditions, laboratory and manufacturing practices, the experimental use of animals and the use and disposal of hazardous or potentially hazardous substances used in connection with our research and development work. The preclinical testing and clinical trials of the products that we or our collaborators develop are subject to extensive government regulation that may prevent us from creating commercially viable products from our discoveries. In addition, the sale by us or our collaborators of any commercially viable product will be subject to government regulation from several standpoints, including manufacturing, advertising and promoting, selling and marketing, labeling, and distributing.

        If, and to the extent that, we are unable to comply with these regulations, our ability to earn revenues will be materially and negatively impacted. The regulatory process, particularly in the biotechnology field, is uncertain, can take many years and requires the expenditure of substantial resources. Biological drugs and non-biological drugs are rigorously regulated. In particular, proposed human pharmaceutical therapeutic product candidates are subject to rigorous preclinical and clinical testing and other requirements by the FDA in the United States and similar health authorities in other

19



countries in order to demonstrate safety and efficacy. We may never obtain regulatory approval to market our proposed products. For additional information about governmental regulations that will affect our planned and intended business operations, see "DESCRIPTION OF BUSINESS—Government Regulation" below.

        Our products may not receive FDA approval, which would prevent us from commercially marketing our products and producing revenues. The FDA and comparable government agencies in foreign countries impose substantial regulations on the manufacture and marketing of pharmaceutical products through lengthy and detailed laboratory, pre-clinical and clinical testing procedures, sampling activities and other costly and time-consuming procedures. Satisfaction of these regulations typically takes several years or more and varies substantially based upon the type, complexity and novelty of the proposed product. We cannot assure you that FDA approvals for any products developed by us will be granted on a timely basis, if at all. Any such delay in obtaining, or failure to obtain, such approvals could have a material adverse effect on the marketing of our products and our ability to generate product revenue. For additional information about governmental regulations that will affect our planned and intended business operations, see "DESCRIPTION OF BUSINESS—Government Regulation" below.

        For-profit entities may be prohibited from benefiting from grant funding.    There has been much publicity about grant resources for stem cell research, including Proposition 71 in California, which is described more fully under the heading "DESCRIPTION OF BUSINESS—California Proposition 71" below. Rules and regulations related to any funding that may ultimately be provided, the type of entity that will be eligible for funding, the science to be funded, and funding details have not been finalized. As a result of these uncertainties regarding Proposition 71, we cannot assure you that funding, if any, will be available to us, or any for-profit entity.

        The government maintains certain rights in technology that we develop using government grant money and we may lose the revenues from such technology if we do not commercialize and utilize the technology pursuant to established government guidelines.    Certain of our and our licensors' research has been or is being funded in part by government grants. In connection with certain grants, the U.S. government retains rights in the technology developed with the grant. These rights could restrict our ability to fully capitalize upon the value of this research.

Risks Relating to Our Reliance on Third Parties

        We depend on our collaborators to help us develop and test our proposed products, and our ability to develop and commercialize products may be impaired or delayed if collaborations are unsuccessful.    Our strategy for the development, clinical testing and commercialization of our proposed products requires that we enter into collaborations with corporate partners, licensors, licensees and others. We are dependent upon the subsequent success of these other parties in performing their respective responsibilities and the continued cooperation of our partners. Our collaborators may not cooperate with us or perform their obligations under our agreements with them. We cannot control the amount and timing of our collaborators' resources that will be devoted to our research and development activities related to our collaborative agreements with them. Our collaborators may choose to pursue existing or alternative technologies in preference to those being developed in collaboration with us.

        Under agreements with collaborators, we may rely significantly on such collaborators to, among other things:

20


        The development and commercialization of potential products will be delayed if collaborators fail to conduct these activities in a timely manner or at all. In addition, our collaborators could terminate their agreements with us and we may not receive any development or milestone payments. If we do not achieve milestones set forth in the agreements, or if our collaborators breach or terminate their collaborative agreements with us, our business may be materially harmed.

        Our reliance on the activities of our non-employee consultants, research institutions, and scientific contractors, whose activities are not wholly within our control, may lead to delays in development of our proposed products.    We rely extensively upon and have relationships with scientific consultants at academic and other institutions, some of whom conduct research at our request, and other consultants with expertise in clinical development strategy or other matters. These consultants are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. We have limited control over the activities of these consultants and, except as otherwise required by our collaboration and consulting agreements to the extent they exist, can expect only limited amounts of their time to be dedicated to our activities.

        In addition, we have formed research collaborations with academic and other research institutions throughout the world. These research facilities may have commitments to other commercial and non-commercial entities. We have limited control over the operations of these laboratories and can expect only limited amounts of time to be dedicated to our research goals.

        We also rely on other companies for certain process development or other technical scientific work. We have contracts with these companies that specify the work to be done and results to be achieved, but we do not have direct control over their personnel or operations. If any of these third parties are unable or refuse to contribute to projects on which we need their help, our ability to generate advances in our technologies and develop our products could be significantly harmed.

General Risks Relating to Our Business

        We may be subject to litigation that will be costly to defend or pursue and uncertain in its outcome.    Our business may bring us into conflict with our licensees, licensors, or others with whom we have contractual or other business relationships, or with our competitors or others whose interests differ from ours. If we are unable to resolve those conflicts on terms that are satisfactory to all parties, we may become involved in litigation brought by or against us. That litigation is likely to be expensive and may require a significant amount of management's time and attention, at the expense of other aspects of our business. The outcome of litigation is always uncertain, and in some cases could include judgments against us that require us to pay damages, enjoin us from certain activities, or otherwise affect our legal or contractual rights, which could have a significant adverse effect on our business.

        We may not be able to obtain third-party patient reimbursement or favorable product pricing, which would reduce our ability to operate profitably.    Our ability to successfully commercialize certain of our proposed products in the human therapeutic field may depend to a significant degree on patient reimbursement of the costs of such products and related treatments at acceptable levels from government authorities, private health insurers and other organizations, such as health maintenance organizations. We cannot assure you that reimbursement in the United States or foreign countries will be available for any products we may develop or, if available, will not be decreased in the future, or that reimbursement amounts will not reduce the demand for, or the price of, our products with a consequent harm to our business. We cannot predict what additional regulation or legislation relating to the health care industry or third-party coverage and reimbursement may be enacted in the future or what effect such regulation or legislation may have on our business. If additional regulations are overly onerous or expensive, or if health care related legislation makes our business more expensive or

21



burdensome than originally anticipated, we may be forced to significantly downsize our business plans or completely abandon our business model.

        Our products are likely to be expensive to manufacture, and they may not be profitable if we are unable to control the costs to manufacture them.    Our products are likely to be significantly more expensive to manufacture than most other drugs currently on the market today. Our present manufacturing processes produce modest quantities of product intended for use in our ongoing research activities, and we have not developed processes, procedures and capability to produce commercial volumes of product. We hope to substantially reduce manufacturing costs through process improvements, development of new science, increases in manufacturing scale and outsourcing to experienced manufacturers. If we are not able to make these or other improvements, and depending on the pricing of the product, our profit margins may be significantly less than that of most drugs on the market today. In addition, we may not be able to charge a high enough price for any cell therapy product we develop, even if they are safe and effective, to make a profit. If we are unable to realize significant profits from our potential product candidates, our business would be materially harmed.

        To be successful, our proposed products must be accepted by the health care community, which can be very slow to adopt or unreceptive to new technologies and products.    Our proposed products and those developed by our collaborative partners, if approved for marketing, may not achieve market acceptance since hospitals, physicians, patients or the medical community in general may decide not to accept and utilize these products. The products that we are attempting to develop represent substantial departures from established treatment methods and will compete with a number of more conventional drugs and therapies manufactured and marketed by major pharmaceutical companies. The degree of market acceptance of any of our developed products will depend on a number of factors, including:

        If the health care community does not accept our products for any of the foregoing reasons, or for any other reason, our business would be materially harmed.

        Our current source of revenues depends on the stability and performance of our sublicensees.    Our ability to collect royalties on product sales from our sublicensees will depend on the financial and operational success of the companies operating under a sublicense. Revenues from those licensees will depend upon the financial and operational success of those third parties. We cannot assure you that these licensees will be successful in obtaining requisite financing or in developing and successfully marketing their products. These licensees may experience unanticipated obstacles including regulatory hurdles, and scientific or technical challenges, which could have the effect of reducing their ability to generate revenues and pay us royalties.

22



        We depend on key personnel for our continued operations and future success, and a loss of certain key personnel could significantly hinder our ability to move forward with our business plan.    Because of the specialized nature of our business, we are highly dependent on our ability to identify, hire, train and retain highly qualified scientific and technical personnel for the research and development activities we conduct or sponsor. The loss of one or more certain key executive officers, or scientific officers, would be significantly detrimental to us. In addition, recruiting and retaining qualified scientific personnel to perform research and development work is critical to our success. Our anticipated growth and expansion into areas and activities requiring additional expertise, such as clinical testing, regulatory compliance, manufacturing and marketing, will require the addition of new management personnel and the development of additional expertise by existing management personnel. There is intense competition for qualified personnel in the areas of our present and planned activities, and there can be no assurance that we will be able to continue to attract and retain the qualified personnel necessary for the development of our business. The failure to attract and retain such personnel or to develop such expertise would adversely affect our business.

        Our credibility as a business operating in the field of human embryonic stem cells is largely dependent upon the support of our Ethics Advisory Board.    Because the use of human embryonic stem cells gives rise to ethical, legal and social issues, we have instituted an Ethics Advisory Board. Our Ethics Advisory Board is made up of highly qualified individuals with expertise in the field of human embryonic stem cells. We cannot assure you that these members will continue to serve on our Ethics Advisory Board, and the loss of any such member may affect the credibility and effectiveness of the Board. As a result, our business may be materially harmed in the event of any such loss.

        Our insurance policies may be inadequate and potentially expose us to unrecoverable risks.    We have limited director and officer insurance and commercial insurance policies. Any significant insurance claims would have a material adverse effect on our business, financial condition and results of operations. Insurance availability, coverage terms and pricing continue to vary with market conditions. We endeavor to obtain appropriate insurance coverage for insurable risks that we identify, however, we may fail to correctly anticipate or quantify insurable risks, we may not be able to obtain appropriate insurance coverage, and insurers may not respond as we intend to cover insurable events that may occur. We have observed rapidly changing conditions in the insurance markets relating to nearly all areas of traditional corporate insurance. Such conditions have resulted in higher premium costs, higher policy deductibles, and lower coverage limits. For some risks, we may not have or maintain insurance coverage because of cost or availability.

        We have no product liability insurance, which may leave us vulnerable to future claims we will be unable to satisfy.    The testing, manufacturing, marketing and sale of human therapeutic products entail an inherent risk of product liability claims, and we cannot assure you that substantial product liability claims will not be asserted against us. We have no product liability insurance. In the event we are forced to expend significant funds on defending product liability actions, and in the event those funds come from operating capital, we will be required to reduce our business activities, which could lead to significant losses.

        We cannot assure you that adequate insurance coverage will be available in the future on acceptable terms, if at all, or that, if available, we will be able to maintain any such insurance at sufficient levels of coverage or that any such insurance will provide adequate protection against potential liabilities. Whether or not a product liability insurance policy is obtained or maintained in the future, any product liability claim could harm our business or financial condition.

        We presently have members of management and other key employees located in various locations throughout the country which adds complexities to the operation of the business.    Presently, we have members of management and other key employees located in both California and Massachusetts, which adds complexities to the operation of our business. We intend to maintain our research facilities in

23



Massachusetts and we have established corporate offices and an additional research facility in California. We will likely continue to incur significant costs associated with maintaining multiple locations.

        We face risks related to compliance with corporate governance laws and financial reporting standards.    The Sarbanes-Oxley Act of 2002, as well as related new rules and regulations implemented by the Securities and Exchange Commission and the Public Company Accounting Oversight Board, require changes in the corporate governance practices and financial reporting standards for public companies. These new laws, rules and regulations, including compliance with Section 404 of the Sarbanes-Oxley Act of 2002 relating to internal control over financial reporting, referred to as Section 404, have materially increased our legal and financial compliance costs and made some activities more time-consuming and more burdensome. Section 404 requires that by 2007 our management assess our internal control over financial reporting annually and include a report on its assessment in our annual report. In 2008 our independent registered public accounting firm may be required to audit both the design and operating effectiveness of our internal controls and management's assessment of the design and the operating effectiveness of our internal control over financial reporting.

Risks Relating to Our Common Stock

        Stock prices for biotechnology companies have historically tended to be very volatile.    Stock prices and trading volumes for many biotechnology companies fluctuate widely for a number of reasons, including but not limited to the following factors, some of which may be unrelated to their businesses or results of operations:

        This market volatility, as well as general domestic or international economic, market and political conditions, could materially and adversely affect the market price of our common stock and the return on your investment.

        A significant number of shares of our common stock have become available for sale and their sale could depress the price of our common stock.    On September 15, 2007, a significant number of our outstanding securities (including the 2005 Debentures, the 2005 Warrants and the shares of common

24



stock underlying such securities) that were previously restricted became eligible for sale under Rule 144(k) of the Securities Act, and their sale will not be subject to any volume limitations.

        Not including the shares of common stock underlying the 2005 Debentures, the 2005 Warrants, the 2006 Debentures, the 2006 Warrants, the replacement warrants, the 2007 Debentures, and the 2007 Warrants, there are presently approximately 92,169,478 outstanding options, warrants and other securities convertible or exercisable into shares of our common stock.

        We may also sell a substantial number of additional shares of our common stock in connection with a private placement or public offering of shares of our common stock (or other series or class of capital stock to be designated in the future). The terms of any such private placement would likely require us to register the resale of any shares of capital stock issued or issuable in the transaction. We have also issued common stock to certain parties, such as vendors and service providers, as payment for products and services. Under these arrangements, we may agree to register the shares for resale soon after their issuance. We may also continue to pay for certain goods and services with equity, which would dilute your interest in the company.

        Sales of a substantial number of shares of our common stock under any of the circumstances described above could adversely affect the market price for our common stock and make it more difficult for you to sell shares of our common stock at times and prices that you feel are appropriate.

        We do not intend to pay cash dividends on our common stock in the foreseeable future.    Any payment of cash dividends will depend upon our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our board of directors. We do not anticipate paying cash dividends on our common stock in the foreseeable future. Furthermore, we may incur additional indebtedness that may severely restrict or prohibit the payment of dividends.

        Our securities are quoted on the OTC Bulletin Board, which may limit the liquidity and price of our securities more than if our securities were quoted or listed on the Nasdaq Stock Market or a national exchange.    Our securities are currently quoted on the OTC Bulletin Board, an NASD-sponsored and operated inter-dealer automated quotation system for equity securities not included in the Nasdaq Stock Market. Quotation of our securities on the OTC Bulletin Board may limit the liquidity and price of our securities more than if our securities were quoted or listed on The Nasdaq Stock Market or a national exchange. Some investors may perceive our securities to be less attractive because they are traded in the over-the-counter market. In addition, as an OTC Bulletin Board listed company, we do not attract the extensive analyst coverage that accompanies companies listed on Nasdaq or any other regional or national exchange. Further, institutional and other investors may have investment guidelines that restrict or prohibit investing in securities traded in the over-the-counter market. These factors may have an adverse impact on the trading and price of our securities.

        Our common stock is subject to "penny stock" regulations and restrictions on initial and secondary broker-dealer sales.    The Securities and Exchange Commission has adopted regulations which generally define "penny stock" to be any listed, trading equity security that has a market price less than $5.00 per share or an exercise price of less than $5.00 per share, subject to certain exemptions. Penny stocks are subject to certain additional oversight and regulatory requirements. Brokers and dealers affecting transactions in our common stock in many circumstances must obtain the written consent of a customer prior to purchasing our common stock, must obtain information from the customer and must provide disclosures to the customer. These requirements may restrict the ability of broker-dealers to sell our common stock and may affect your ability to sell your shares of our common stock in the secondary market.

USE OF PROCEEDS

        We will not receive proceeds from the sale of shares under this prospectus by the selling security holders. We may, however, receive the exercise price of the warrants if and when those warrants are exercised by the selling security holders. Whether we receive any proceeds depends upon whether the holders of the warrants utilize their cashless exercise rights. Such amounts, if any, that we receive upon exercise of the warrants will be used for general corporate purposes.


SELLING SECURITY HOLDERS

        The securities are being offered by the named selling security holders below. The selling security holders hold common stock (or securities convertible or exercisable into common stock), the terms of which are described below under "DESCRIPTION OF SECURITIES." The selling security holders may, from time to time, offer and sell any or all of the shares that are registered or will be registered under this prospectus, although they are not obligated to do so.

        The selling security holders listed in the Selling Security Holder Table below each received (i) the 2007 Debentures, which are convertible into shares of our common stock, and/or (ii) the 2007 Warrants, which our exercisable into shares of common stock, in connection with the closing of the private placement in September 2007. As a result of certain contractual obligations, we are registering pursuant to this Registration Statement shares of common stock underlying these securities.

        The following table sets forth, to the best of our knowledge and belief, with respect to the selling security holders:

        Some of the shares of common stock underlying the debentures and warrants included in the following table may have already been sold, transferred or disposed of by the selling security holders.

        The registration of the offered shares does not mean that any or all of the selling security holders will offer or sell any of these shares. Except as set forth in the notes to these tables, there is not nor

26



has there been a material relationship between us and any of the selling stockholders within the past three years. We believe, based on information supplied by the following selling security holders, that the natural persons named in the "Information Regarding Institutional Selling Security Holders" section of this prospectus following these tables exercise the sole or shared voting and/or dispositive powers with respect to the shares registered for resale in this prospectus.

Prior Securities Transactions between the Company and Selling Security Holders

        On January 31, 2005, the small business issuer entered into a merger pursuant to which it effected a complete change of business. Upon the completion of the merger, the issuer ceased all of its pre-merger operations and adopted the business of the company as it exists today. Prior to the merger, the issuer had minimal business, operations, revenues and assets, and had been involved in an industry entirely unrelated to the business of the company as it exists today. As a result, the following table sets forth all prior securities transactions between us and the selling security holders, any affiliates of such selling security holders or any person with whom any selling security holder has a contractual relationship regarding such securities transactions, since January 31, 2005, the date of the merger.

PLAN OF DISTRIBUTION

        Each selling security holder and any of their pledgees, assignees and successors-in-interest may, from time to time, sell any or all of their shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. A selling security holder may use any one or more of the following methods when selling shares:

        The selling security holders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

        Broker-dealers engaged by the selling security holders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with NASDR Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with NASDR IM-2440.

        In connection with the sale of the common stock or interests therein, the selling security holders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling security holders may also sell shares of the common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling security holders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this

40



prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

        The selling security holders and any broker-dealers or agents that are involved in selling the shares may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling security holder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the common stock. In no event shall any broker-dealer receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%).

        We are required to pay certain fees and expenses incurred by us incident to the registration of the shares. We have agreed to indemnify the selling security holders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

        Because selling security holders may be deemed to be "underwriters" within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus. Each selling security holder has advised us that it has not entered into any written or oral agreements, understandings or arrangements with any underwriter or broker-dealer regarding the sale of the resale shares. There is no underwriter or coordinating broker acting in connection with the proposed sale of the resale shares by the selling security holders.

        We have agreed to keep this prospectus effective until the earlier of:

        The resale shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

        Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale shares may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling security holders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of shares of the common stock by the selling security holders or any other person. We will make copies of this prospectus available to the selling security holders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale.

DESCRIPTION OF BUSINESS

        Overview.    We are a biotechnology company focused on developing and commercializing human embryonic and adult stem cell technology in the emerging field of regenerative medicine.

        We have acquired, developed and maintain a portfolio of patents and patent applications that form the proprietary base for our research and development efforts in the area of embryonic and adult stem cell research. We believe that our intellectual property represents one of the strongest portfolios in the field. We employ a team including some of the world's leading scientists in the field of stem cell research and development and experts in the conduct of clinical trials. We believe our technology base, in combination with our know-how, provides a competitive advantage and will facilitate the successful development and commercialization of products for use in treatment of a wide array of chronic degenerative diseases and in regenerative repair of acute disease, such as trauma, myocardial infarction and burns.

        Our belief that our intellectual property represents one of the strongest portfolios in the field is supported by:

        Regenerative medicine is a new and emerging field of study involving development of medical therapies based on advances in stem cell and nuclear transfer technology. We have developed and maintain a broad portfolio with ownership or exclusive licensing of over 50 issued patents and over 270 patent applications in the field of regenerative medicine and related technologies. This significant volume of patents and patent licenses has been developed in the short span of approximately the past seven to ten years.

        Although we have strong competitors in this field, there are a limited number of companies operating in this field. We believe our intellectual property portfolio compares favorably with those of our competition based upon its size, focus and filing dates.

48



        With respect to the focus of our human embryonic stem cell portfolio, we believe that somatic cell nuclear transfer and chromatin transfer are, and will prove to be, one of the technological keys to successful development of stem cell therapies. See "Cellular Reprogramming" below. We own or have license to numerous other technologies for dealing with transplant rejection, including means of activating oocytes during nuclear transfer, parthenogenesis, transdifferentiation, and dedifferentiation. Our intellectual property also includes patent rights and applications for specific applications of stem cell technology in producing retinal pigment epithelium, hemangioblasts, myoblast stem cells and numerous methods and compositions for the use of these technologies and derived cells in heart disease, immunodeficiency estates and cancer.

        With respect to the company's myoblast program, we believe that the technology has demonstrated that a myoblast transplantation treatment is feasible and safe in clinical trials conducted to date and that the technology could address the large market potential presented by heart failure.

        This is a young and emerging field. There can be no assurances that our intellectual property portfolio or ongoing clinical trials will ultimately produce viable commercialized products and processes; however, at this early stage of development, our intellectual property and science team are well-recognized leaders in the field. See "RISK FACTORS—Risks Relating to Our Technology" on page 8 of this prospectus.

        Our research efforts to date in human embryonic technologies are at the level of clinical trials, pre-clinical development and basic research. Our myoblast program has received FDA clearance to proceed to Phase II human clinical trials. We are focused on leveraging our key assets, including our intellectual property, our scientific team, our facilities and our capital, to accelerate the advancement of our stem cell technologies. In addition, we are pursuing strategic collaborations with members of academia, industry and foundations to further accelerate the pace of our research efforts. We are currently headquartered in Alameda, California, with additional research and development offices in Worcester, Massachusetts and Charlestown, Massachusetts.

        The Field of Regenerative Medicine.    The emerging field of treatment called "regenerative medicine" or "cell therapy" refers to treatments that are founded on the concept of producing new cells to replace malfunctioning or damaged cells as a vehicle to treat disease and injury. Our focus is the development of effective methods to generate replacement cells from both human embryonic and adult stem cells. Many significant and currently untreatable human diseases arise from the loss or malfunction of specific cell types in the body. This is especially true of diseases associated with aging such as Alzheimer's disease, Parkinson's disease, type II diabetes, heart failure, osteoarthritis, and aging of the immune system, known as immunosenescence. This is also true for medical conditions resulting from damage to cells due to acute disease, such as trauma, infarction and burns. We believe that replacing damaged or malfunctioning cells with fully functional ones may be a useful therapeutic strategy in treating many of these diseases and conditions.

        A stem cell is a cell that has the ability to branch out and change, or differentiate, into two or more different cell types. Stem cells are self-renewing primitive cells that have the ability to develop into functional, differentiated cells. In general, there are two broad categories of stem cells: adult stem cells and embryonic stem cells. Adult stem cells are derived from various tissues in the human body. Because they can branch out into many different cell types, they are referred to as "multipotent." Multipotent means these cells develop into multiple, but not all, types of cells in the body. Embryonic stem cells, referred to as ES cells, which are derived from pre-implantation embryos, are unique because they are "pluripotent," which means that they can develop into all cells and tissues in the body, and they self-renew indefinitely in their undifferentiated state. The ability of ES cells to divide indefinitely in the undifferentiated state without losing pluripotency is a unique characteristic that distinguishes them from all other stem cells discovered to date in humans.

49


        Our business is focused on both the development and commercialization of ES cell based technologies and adult stem cell transplantation therapies. Our adult stem cell-based products are specifically targeted at therapies for heart and other cardiovascular disease and are at a more advanced stage of development than our human ES cell based technologies. By contrast, our human ES cell-based technologies are not yet in clinical trials, but we believe these technologies have potentially broader and more powerful applications with respect to a wide range of diseases.

        Since the discovery of the human ES cell, medical researchers worldwide have generally recognized the significance of this new technology and have begun to focus research on the translation of this discovery into important new therapies. Specifically, researchers have focused on several key challenges including:

        We believe that solving the potential rejection of ES cells in patients is the greatest scientific obstacle to developing successful therapeutics. Our research and technologies are focused on solving this obstacle by creating stem cell therapeutics with compatible tissues. Compatible tissues are referred to as being histocompatible.

        We believe the potential markets for regenerative medicine and stem cell therapy are large. The table below summarizes the potential United States patient populations which we believe may be amenable to cell or organ transplantation and represent target markets for products generated through our regenerative medicine technology.

        Our Human Embryonic Stem Cell Technologies.    The ability to produce embryonic stem cells that are immunologically compatible with the patient is the hallmark and the strength of our technology platform. We believe our technology platform will enable the transformation of a patient's cells into an embryonic state where those cells can be differentiated into specific therapeutically relevant cell types that are genetically identical to the patient. We believe our technology may also enable the production of stem cell lines, from sources external to the patient, that have a sufficiently high level of histocompatibility to be useful in making cell therapies readily accessible to a large segment of the patient population, without the need for exact genetic matching of tissues. As a result, our technology avoids reliance on more limited approaches that involve use of cell lines that are not histocompatible with the recipient, or therapies based upon use of adult stem cells.

        In August 2001, the President of the United States set guidelines for federal funding of research on embryonic stem cells from human embryos created by in-vitro fertilization, referred to as IVF. IVF-ES cells have the drawback that they are not genetically matched to the recipient patient. These ES cells are allogeneic. The word allogeneic literally means "other DNA type." Therapies using allogeneic cell lines can result in immune system incompatibilities where the host immune system attacks and rejects the transplanted cells or the transplanted cells attack the host. These incompatibilities may be partially suppressed with powerful immunosuppressive drugs, but the side effects can be severe and result in life-threatening complications. As a result, these incompatibilities will generate significant inefficiencies in the application of cell therapies.

        The strategic focus of our human ES cell technology is to produce cell lines that are both histocompatible with the patient and pluripotent. We have numerous proprietary technologies that we believe will generate histocompatible, pluripotent stem cells for patient-specific application. These cells maximize the potential for effective use as transplants to replace diseased or destroyed cells in human patients. If successfully developed, our cellular reprogramming technologies will make it possible to produce cells that have the proliferative capacity of young cells, have specific therapeutic application, and are immunologically compatible with the patient.

        All of our ES cell technologies are at the level of basic research or in the pre-clinical stage of development.

        Our ES Cell Research Programs.    Our ES cell research programs are divided into three core categories: cellular reprogramming, our reduced complexity program, and stem cell differentiation. Each of these core areas of focus are discussed below.

        Cellular Reprogramming.    This research program involves development of therapies based on the use of genetically identical pluripotent stem cells generated by our cellular reprogramming technologies. These technologies can be used to generate patient-specific pluripotent cells and tissues for transplantation. We believe our technology platform will enable the transformation of a patient's cell into pluripotent ES cells that are histocompatible with the patient and have the potential to be differentiated into any of the over 200 different human cell types that may be therapeutically relevant in treating diseased or destroyed tissues in human patients. We expect that our cellular reprogramming technologies will offer a new avenue for the introduction of targeted genetic modifications in cells and for the regeneration of cell lifespan, thereby making youthful cells available for aging patients. The combination of these advances, the ability to produce young cells of certain kinds that are histocompatible with the patient, is a core potential application of our technology. We believe these cellular reprogramming technologies will be effective therapies where there is time to prepare customized therapy through reprogramming of the patient's own cells.

51



        Some of the technologies that support our cellular reprogramming program are somatic cell nuclear transfer, chromatin transfer, and fusion technologies.

        Somatic cell nuclear transfer, referred to as SCNT, refers to the process wherein a body cell is transferred to an egg cell from which the nuclear DNA has been removed. This results in the body cell being "reprogrammed" by the egg cell. This reprogramming transforms the cell from the type of cell it was, for instance a skin cell, into an embryonic cell with the power to become any cell type in the body. A related technology is called chromatin transfer. Through this technology, the DNA and attached proteins, or chromatin, of the somatic cell is reprogrammed prior to transfer into an egg cell. Chromatin transfer has the potential to improve the efficiencies and therefore reduce the cost of nuclear transfer. We believe that one critical advantage of our proprietary SCNT and chromatin transfer technologies is that the cells are "rejuvenated" by returning the cell to a youthful state. This is important because these youthful cells will have the proliferative capacity of young cells. These healthy replacement cells, which would be genetically identical to the patient's own cells, would then be used for cell transplantation.

        Our fusion technologies involve the fusion of the cytoplasm of one cell into another. In the same manner that the cytoplasm of an egg cell is capable of transforming any cell back to an embryonic state, the fusion of the cytoplasm of other cell types, including differentiated cell types (such as blood cells) is capable of reprogramming another cell type, such as a skin cell. These technologies have the potential of transforming a cell from a patient into another medically-useful cell type also identical to the patient. They also have the potential to fuse the cytoplasm of undifferentiated cells, such as embryonic stem cells, with somatic cells to transport the somatic cell DNA back to pluripotency. We believe that the fusion technology we are developing can be developed into as broad and powerful a technique as SCNT, producing histocompatible, youthful stem cells that are multi and potentially even pluripotent. If successfully developed, this technology may also provide a pathway that does not utilize human egg cells which would reduce the cost of the procedure and increase the number of patients that could benefit from its implementation.

        Stem Cell Differentiation.    Regenerative medicine requires that stem cells, from whatever source derived, be differentiated, or re-differentiated, into specific body cell types and then physically transplanted into a patient. Differentiation into tissues such as cardiac muscle, blood, and other tissues occurs spontaneously in ES cells being cultured in a dish. Successful application of stem cell technology will require control over the specific kinds of cells into which stem cells differentiate. Control of differentiation and the culture and growth of stem and differentiated cells are important current areas of research for us. Also, some chemicals, such as retinoic acid, can be used to trigger differentiation into specific cell types such as nerve cells. We intend to pursue differentiation approaches both in-house and through collaborations with other researchers who have particular interests in, and skills related to, cellular differentiation. These efforts include using both animal and human stem cell lines. Our research in this area includes projects focusing on developing many different cell types that may be used in the future to treat a wide range of diseases.

        Currently our researchers are working on projects to generate stable cell lines with particular focus on retinal pigment epithelium, or RPE, cells, and hemangioblast cells.

        Retinal Pigment Epithelium Program.    In November, 2006 we published data demonstrating human ES cell-derived RPE cells were capable of rescuing visual function in Royal College of Surgeon rats. Following the publication of that data, we entered into a pre-clinical development collaboration with Casey Eye Institute at Oregon Health & Science University. The purpose of the collaboration is to conduct dosage and safety studies in preparation for IND and Phase I human clinical trials.

        Hemangioblast Program.    Hemangioblasts are a newly-characterized stem cell capable of differentiating into both hematopoietic, meaning blood cell forming, and angiogenic, meaning blood

52



vessel endothelium forming, cells. We believe it will be possible to utilize hemangioblast cells in engraftment to repair age-related endothelial dysfunction associated with numerous significant age-related diseases, including cardiovascular disease, stroke, and even perhaps cancer. In 2006 we successfully derived hemangioblast cells generated from the company's blastomere-derived human embryonic stem cell lines. In 2007, we published data reporting that through utilization of hemangioblast based therapy we generated function in vivo with respect to the repair of eschemic retinal vasculatures and restoration of blood flow in eschemic limbs. In addition, we also reported increased survival rates of animals suffering from myocardial infarction.

        Our adult stem cell-based program is developing an autologous myoblast transplantation therapy delivered using a minimally invasive catheter injection system to restore cardiac function in patients with advanced heart disease. The key target for the therapy will be heart failure patients with New York Heart Association ("NYHA") scores Class II to IV. The company's therapy could also benefit patients supported on ventricular assistance devices and potential additional indications, such as acute myocardial infarction, peripheral artery disease, and non-cardiac tissue repair. Currently available treatment options for heart failure patients are inadequate and can only slow the progression of heart failure; none can halt or reverse the process. We believe our autologous myoblast transplantation therapy uses patented myoblast compositions for catheter delivery to the heart offering repair of the disease in heart failure patients and for those end-stage disease patients on ventricular assistance device support. These indications represent a significant unmet medical need and hold significant potential for clinical approval.

        Our transplantation therapy involves extraction through simple biopsy from a patient's thigh of myoblasts, which are non-embryonic, skeletal muscle stem cells, that can be expanded in culture and injected back into damaged and scarred regions of the heart. This therapy promotes repair of damaged cardiac tissue by autologous cells, thereby avoiding immune rejection as each patient receives their own cells. Skeletal muscle, unlike heart muscle, can repair itself after injury. Skeletal muscle contains immature myoblasts that can fuse with surrounding myoblasts or with damaged muscle fibers to regenerate contractile skeletal muscle. In experimental models, our researchers have demonstrated that skeletal myoblasts can be transplanted into an infarcted myocardium with the subsequent development of elongated, striated cells characteristic of both skeletal and cardiac muscle. Our Phase I clinical studies have demonstrated the efficacy of this therapy on a preliminary basis. Our Phase II and III studies planned for commencement in 2008 will evaluate the applications for myoblast transplantation in slowing and/or reversing the impact of heart failure.

        We perform our myoblast expansion, packaging, shipment, and quality testing using proprietary procedures that adhere to GMP regulations for manufacturing clinical trial material. After expansion, the myoblasts are packaged and delivered to the clinical site for implantation into the injured heart tissue by a surgeon or interventional cardiologist. To maximize cell therapy effectiveness, adequate numbers of cells must be delivered to the site of damage in a repeatable and safe manner. Our therapy utilizes a minimally invasive catheter-based delivery methodology, which provides a safe, targeted and high efficiency approach to cell delivery to the infarct area.

        We have completed preclinical testing, two multi-center Phase I clinical trials and a multi-center Phase Ib clinical trial and we anticipate initiating at least one multi-regional, Phase II study in 2008.

        We believe that, unlike currently available treatment options, myoblast therapy has the ability to repair and improve the function of a damaged heart. Our preclinical and clinical studies support the conclusion that our therapy presents significant advantages over currently available treatments, including:

53


        Potential Commercial Applications of our ES Cell and Adult Stem Cell Technologies.    We believe that, if successfully developed, stem cell-based therapy has the potential to provide treatment for a broad range of acute and chronic degenerative diseases. We believe the potential applications of cell-based therapeutics include


        While we expect that any future products will take the form of medical procedures, tangible therapeutics, or combinations thereof, we currently have no products, and the identity of our future products, if any, is dependent upon the results of our ongoing research efforts, and, therefore cannot be determined at this time.

Our Intellectual Property.

        Our research and development is supported by a broad intellectual property portfolio. We currently own or have exclusive licenses to over 50 patents and have over 270 patent applications pending worldwide in the field of regenerative medicine and stem cell therapy. We also have non-exclusive rights to a portfolio of patents and patent applications that support our core intellectual property.

        Our success will likely depend upon our ability to preserve our proprietary technologies and operate without infringing the proprietary rights of other parties. However, we may rely on certain proprietary technologies and know-how that are not patentable. We protect our proprietary information, in part, by the use of confidentiality agreements with our employees, consultants and certain of our contractors.

        We maintain a disciplined patent policy and, when appropriate, seek patent protection for inventions in our core technologies and in ancillary technologies that support our core technologies or which we otherwise believe will provide us with a competitive advantage. We pursue this strategy by filing patent applications for discoveries we make, either alone or in collaboration with scientific collaborators and strategic partners. Typically, although not always, we file patent applications both in the United States and in select international markets. In addition, we plan to obtain licenses or options to acquire licenses to patent filings from other individuals and organizations that we anticipate could be useful in advancing our research, development and commercialization initiatives and our strategic business interests.

Actual patent expiration dates may differ from the dates listed herein including due to patent term adjustments pursuant to 35 U.S.C. § 154(b) and 37 C.F.R. §§ 1.702-1.705.

        The fundamental consequence of patent expiration is that the invention covered by that patent will enter the public domain. However, the expiration of patent protection, or anticipated patent protection, for the bulk of our portfolio is not scheduled to begin for approximately ten to fifteen years. Due to the rapid pace of technology development in this field, and the volume of intellectual property we anticipate will be generated over the next decade, it is unlikely that the expiration of any existing patents or patent rights would have an adverse affect on our business. Due to our current stage of development, as described under the heading "MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION" appearing elsewhere in this prospectus, our existing patent portfolio is not currently supporting a marketed product, so we will not suffer from any reduction in product revenue from patent expiration. Any actual products that we develop are expected to be supported by intellectual property covered by current patent applications that, if granted, would not expire for 20 years from the date first filed. For example, our patent rights under the University of Massachusetts license listed in the patent table, above, do not begin to expire until 2016. Due to the early stage of our business, we differ from, for example, the pharmaceutical industry where the loss of a key significant patent can result in contemporaneous loss of products, programs or revenues. As our table demonstrates, our business is at the front end of the patent protection spectrum and is not expected to be significantly impacted by expiration of existing patents or patents issued in response to existing applications.

Research and License Agreements.

Licenses of Intellectual Property to Us

        The following summarizes technology licensed to us.

58



        UMass License.    On February 1, 2002 and April 16, 1996, we entered into exclusive license agreements with the University of Massachusetts. The 1996 Agreement has been amended by amendments dated September 1, 1997, May 31, 2000 and September 19, 2002. Pursuant to these agreements, the University of Massachusetts, referred to as UMass, exclusively licensed to us certain biological materials, patent rights and related technology for commercialization in specified fields. The license agreements require us to use diligent efforts to develop licensed products and licensed services and require us to pay certain royalties, minimum annual royalties, milestone payments and sublicense income to UMass. UMass received 73,263 shares of common stock of ACT as partial consideration of the license granted.

        2002 License.    Under the 2002 license, UMass licenses to us certain patent rights relating to the cloning of non-human animals for use in connection with the development, manufacture and sale of products and services in the field of non-human animals for agriculture, companion animals, research and diagnostic products, non-human and human therapeutics, and neutraceuticals, except production of immunoglobulin in the blood of Bos taurus and Bos indicus. We are required to pay royalties to UMass ranging from 1.5% to 2.0% based on the covered product or service. We agreed to pay minimum royalty payments of $15,000 on the first and second anniversary of the agreement, $20,000 on the third anniversary, $25,000 on the fourth anniversary, and increasing to $45,000 on the fifth anniversary and for each year thereafter. We also agreed to make milestone payments to UMass of up to $1,630,000 upon the achievement of various development and commercialization milestones. Finally, we have agreed to pay UMass 18% of all sublicense income.

        1996 License.    The 1996 license covers certain patent rights, biological materials and know-how related to the cloning of non-human animals and cells for use in cell fields except the production of immunoglobulin in the blood of Bos taurus and Bos indicus. We are required to pay royalties ranging from 2.5% to 4.5% on net sales of products and services covered by the license, and minimum royalty payments in the amount of $15,000 per year (beginning on the later of the fourth year after the effective date of the agreement or the completion of certain clinical trials) for net sales on products and services for use in human therapeutics, and $30,000 per year (beginning in the third year after the effective date of the agreement) for net sales on products and services for all uses other than in human therapeutics. UMass agreed to waive minimum royalty payments during any calendar year in which we fund research at UMass in the aggregate amount of $300,000. There are no milestone payments. We agreed to pay UMass 18% of all sublicense income except for equity. With respect to equity, we are required to pay UMass an amount equal to 10% of the total equity we receive for any transfer of rights under the 1996 license.

        Both the 2002 agreement and the 1996 agreement remain in effect until all issued patents within the patent rights licensed under the agreement have expired, or for a period ten years after the effective date of the agreement if no patents have issued within that ten-year period. Each party has the right to terminate the agreement upon the occurrence of a material uncured breach. We also have the right to terminate at any time for any reason with ninety days' written notice.

        GTC License.    On September 25, 1997, we entered into a development and commercialization agreement with GTC Biotherapeutics, formerly known as Genzyme Transgenics Corporation, which was superseded by an exclusive development and license agreement dated June 8, 1999, pursuant to which each party exclusively licensed to the other certain patent rights and technology for use in defined fields and pursuant to which we agreed to provide certain related services. The agreement also requires each party to disclose to the other on a periodic basis a written report of developments relevant to the other party's field.

        Under the agreement, GTC licenses certain patent rights to us that are useful to:

59


        In addition, under the agreement we license to GTC certain patent rights and know-how useful to the cloning of animals for all purposes for the production of biopharmaceutical agents in milk, including, but not limited, proteins, peptides and polypeptides for pharmaceutical, neutraceutical or other use.

        Under the agreement, we agreed by September 1, 2000, to produce at least 20 cloned hSA cows (cows produced with our technology that are transfected with a GTC recombinant DNA construct and contain the hSA transgene and express hSA in their milk for the purpose of transgenic production of milk products.)

        We are required to pay GTC a royalty in the amount of 3% of net sales of products covered by the GTC license, which is reduced to 2% in the event net sales of such products exceed $25 million per calendar quarter for two consecutive calendar quarters. GTC is required to pay royalties to us in the amount of 2% of net sales of products consisting of hSA produced in the milk of hSA cows, which is reduced to 1% in the event net sales exceed $12,500,000 per calendar quarter for two consecutive calendar quarters, and 3% of net sales of products consisting of proteins other than hSA in the milk of transgenic animals, which is reduced to 2% in the event sales exceed $25 million per calendar quarter for two consecutive quarters. GTC agreed to pay us an annual fee of $100,000 to maintain exclusivity rights granted to GTC, which may be increased to $1 million if GTC does not enter into agreements with third parties to develop two additional products covered by the patent rights licensed to GTC under the agreement every two years. Each party also agrees to pay to the other 25% of any and all fees obtained in connection with the sublicensing of the other party's intellectual property. There are no milestone payments under the agreement. The licenses granted in the agreement continue in force until the expiration of all patent rights included in the licenses. The agreement may be terminated by either party in the event of an uncured breach.

        Wake Forest License.    On January 26, 2001, we entered into a materials and research data license agreement with Wake Forest University, pursuant to which WFU granted to us a worldwide, exclusive, royalty-free, perpetual and irrevocable right and license to use certain data and stem cells and stem cell cultures created by us from biological materials provided by WFU to us for specified purposes only. The agreement allows us to utilize certain primate skin cells and ovary materials produced by WFU and transferred to us pursuant to an agreement relating to the transfer of biological materials. There are no milestone payments. There are no royalty requirements unless we desire to negotiate a commercial license for use of the biological materials provided to us by WFU. WFU received 60,000 shares of common stock of ACT Group, Inc., a now dissolved Delaware corporation referred to hereinafter as ACT Group. We have agreed to provide WFU samples of stem cells for WFU's research, education and teaching purposes and we have a first option to obtain an exclusive license to any intellectual property rights claimed by WFU in connection with the use of such stem cells. The term of the license granted is perpetual and irrevocable absent a breach by us.

        WiCell 2002 License.    In March 2002, we entered into an industry research license and material transfer agreement with WiCell Research Institute, Inc., referred to as WiCell, pursuant to which WiCell granted to us a non-exclusive license, with no right to sublicense, to make, use and sell or otherwise transfer certain primate embryonic stem cells and derivatives thereof for internal research purposes and to receive such primate embryonic stem cells or derivatives from third parties for internal research purposes. In consideration of the license granted to us by WiCell, we agreed to pay a license fee of $100,000 and an annual maintenance fee of $25,000. The license includes a grant from us to WiCell of a non-exclusive, royalty-free, irrevocable, paid-up research license under any inventions made by or for us to the extent that such inventions are a modification of an invention described in the licensed patent rights.

60


        WARF and WiCell 2007 License.    On May 2, 2007, we entered into a commercial products addendum with the Wisconsin Alumni Research Foundation ("WARF") and its subsidiary, WiCell Research Institute, Inc., ("WiCell"). The addendum amends in certain respects the industry research license and material transfer agreement discussed above. The addendum (i) grants to us a non-exclusive, world-wide commercial license to 23 issued patents and 123 patents pending to pursue therapeutic and research products utilizing human embryonic stem cell technology and (ii) provides for certain sublicensing rights to enable us to further the development and commercialization of products. The addendum requires us to make certain royalty payments and pay license fees to WARF as set forth in the addendum.

        Kirin License.    Effective May 9, 2006, we entered into an exclusive license agreement with Kirin Beer Kabushiki Kaisha, and its subsidiaries Aurox, LLC, Hematech, LLC and Kirin SD, Inc. (which we collectively refer to as Kirin), pursuant to which Kirin exclusively licensed to us certain patent rights, with the right to sublicense, for use in connection with the research, development, manufacture and sale of therapeutic and diagnostic human cell products. The agreement also requires Kirin to disclose to us on a periodic basis a written report of improvements to the patent rights.

        In consideration of the rights and licenses granted to us, we paid Kirin an initial license fee and we have agreed to pay royalties representing a percentage of the net sales of all royalty-bearing products and services covered by the license. We are also required to pay a minimum annual royalty payment under the license. We also agreed to pay Kirin a percentage of any and all fees obtained in connection with the sublicensing of the patent rights. There are no milestone payments under the agreement. The license granted in the agreement continues in force until the expiration of all patent rights included in the license or for a period of 10 years from the effective date of the agreement if no patents have issued within that 10-year period. The agreement may be terminated by either party in the event of an uncured breach, and the agreement may also be terminated by us at any time by giving written notice to Kirin.

        TranXenoGen License.    On March 24, 2006, we entered into an exclusive sublicense agreement with TranXenoGen, Inc., pursuant to which TranXenoGen exclusively sublicensed to us certain patent rights owned by Brandeis University and technology, with the right to sublicense, for use in defined fields. The agreement also provides us with a right of first negotiation for any improvement patents controlled by TranXenoGen. The agreement is subject to certain terms and conditions included in an exclusive license agreement between TranXenoGen and Brandeis University.

        The field includes:

61


        The field does not include the use of human reproductive cells, embryos or tissues (as defined in the agreement) or human cloning, but we are exploring the possibility of expanding the field to allow use of the licensed patent rights and technology in the human field.

        In consideration of the rights and licenses granted to us, we paid TranXenoGen an initial license fee of 163,399 shares of common stock and $150,000 in cash, and we have agreed to pay royalties of 2% or 3% (depending on the nature of the product or service) of the net sales of all royalty-bearing products and services covered by the license. Under the agreement we are also required to pay an annual license maintenance fee of $25,000, which is creditable against royalty and sublicense income payments. We also agreed to pay TranXenoGen sublicense income of 10% or 50% of sublicense income received by us; the amount of sublicense income payable to TranXenoGen in a particular instance will depend on the nature of the sublicense income. We also agreed to pay TranXenoGen a milestone payment of $100,000 if TranXenoGen obtains certain patent claims in a U.S. issued patent.

        The license granted in the agreement continues in force until the expiration of all patent rights. The agreement may be terminated by either party in the event of an uncured breach, and the agreement may also be terminated by us at any time by giving 90 days prior written notice to TranXenoGen. We may also terminate the agreement if the agreement between TranXenoGen and Brandeis University is terminated.

        In May, 2007 Brandeis University terminated its license agreement with TranXenoGen. Pursuant to the terms of our license with TranXenoGen we are in the process of negotiating a direct license to the patent rights owned by Brandeis University.

        Start Licensing License.    On August 30, 2006, we entered into a Settlement and License Agreement with UMass and Start Licensing, Inc. Pursuant to this agreement Start Licensing licenses to us, on a nonexclusive, royalty-free and paid-up basis, certain patent rights for use with non-human animal research or studies, including preclinical trials, in connection with the research, development and sale of therapeutic and diagnostic human cell products.

        Cardion License.    Cardion Pharmaceuticals, Inc. and Diacrin, Inc. entered into a patent license agreement on September 30, 2002; the agreement was transferred to our wholly owned subsidiary Mytogen, Inc. on December 28, 2005. Under the agreement, Mytogen has a worldwide, non-exclusive right and license under certain specified patent rights, with the right to sublicense, to make, have made, use, have used, offer for sale, sell, lease, import and/or otherwise dispose of products in the field described as cell-transplantation treatments and related therapies that use genetically unmodified skeletal myoblasts for the treatment of cardiovascular disease. Under the agreement Mytogen is required to make certain milestone payments (ranging from $500,000 to $1,500,000 upon the occurrence of specified events), an annual maintenance fee of $25,000.00, and earned royalties equal to (i) 5% of the net sales price of all covered products sold to its end-user customers and (ii) 5% of net sales of covered products sold by Mytogen's sublicensees.

        GenVec Agreement.    On December 28, 2005, Mytogen and GenVec, Inc. entered into a patent assignment and security agreement. Under the agreement, as amended on July 31, 2007, GenVec assigned certain agreements and intellectual property to Mytogen, and retained a royalty-free non-exclusive license, with the right to grant sublicenses, to practice the intellectual property in connection with products, processes or services developed or provided by GenVec other than autologous and allogenic skeletal myoblasts for cardiac therapy. Under the original agreement, Mytogen granted a security interest in the assigned intellectual property, but the security interest was released in the amendment to the agreement. Under the agreement, as amended, Mytogen must use commercially reasonable efforts to commercialize the assigned intellectual property, including by spending specified amounts in support of research and development in support of such commercialization; Mytogen must pay GenVec one-half of the first milestone payment (anticipated to be two million U.S. dollars)

62



received by Mytogen under the Terumo Agreement; and Mytogen must also pay GenVec four percent (4%) of the net sales revenue from sales or other provision of products, processes or services covered by the agreement.

Exclusive Licenses of Intellectual Property by Us

        The following summarizes licenses from us to third parties.

        GTC License.    On June 8, 1999, we entered into an exclusive development and license agreement with GTC Biotherapeutics. See description of this agreement above.

        Exeter Life Sciences License.    On October 22, 2003, we entered into an exclusive license with Exeter Life Sciences, Inc., pursuant to which we exclusively licensed to Exeter certain technology and patent rights for use in the fields of agriculture, endangered species, companion animals and equine animals. The license also grants Exeter a right of first negotiation to any improvement patents that are obtained by us that relate to the licensed intellectual property or which are useful, necessary or required to develop or manufacture certain animals, cells or tissues within the defined fields of use.

        Under the agreement, we license rights to certain patent rights and technology useful for the fields of use of non-human animals for agriculture, endangered animals and companion animals; excluding production of such animals for the primary purpose of producing human and non-human animal therapeutics and human healthcare products, including without limitation the production of biopharmaceutical agents in milk, such as proteins, peptides and polypeptides for pharmaceutical, neutraceutical or other use, and excluding the production of immunoglobulin in the blood of Bos taurus and Bos indicus. The field includes:


        In consideration of the rights and licenses granted to Exeter, Exeter paid to us an initial license fee of $1,000,000, and has agreed to pay royalties equal to 5% of the net sales of all products and services covered by the license; provided that, sublicense income for license products that are the progeny of cloned animals covered by the license or products obtained from such progeny, the royalty is 3%. Exeter is required to pay an annual maintenance fee for the license, equal to $100,000 in 2005, increasing annually by $50,000 up to $500,000. Exeter's obligation to pay the annual maintenance fee is suspended unless and until certain intellectual property that is the subject of litigation, namely the matter styled University of Massachusetts v. James M. Robl and Phillipe Collas, Massachusetts Superior

63


Court, Suffolk County, Docket No. 04-0445-BLS, is recovered and licensed to us and included in the license to Exeter. The license also provides that we will refund certain amounts to Exeter if certain conditions concerning the referenced litigation are not met and that we will extend to Exeter rights associated with "improvement patents" that are obtained by us or the University in connection with the referenced litigation or any patent interference or opposition proceedings involving us that relate to the licensed intellectual property or which are useful, necessary or required to develop or manufacture cloned and/or transgenic non-human animals and cloned and/or transgenic cells and tissues from non-human animals within the field of use. The license grants Exeter a right of first negotiation to any improvement patents. There are no milestone payments. Exeter agrees to pay us a total of 25% of all sublicense income under the license. Either party may terminate the agreement in the event of an uncured breach. Exeter may terminate without cause on 60 days' prior written notice to us, or may terminate immediately in the event of a change in law that materially affects Exeter's ability to commercialize the licensed intellectual property under the license.

        We expect that the Exeter Life Science License will be amended as a result of the Start Settlement and the settlement of the University of Massachusetts and Advanced Cell Technology, Inc. v. Roslin Institute (Edinburgh), Geron Corporation and Exeter Life Sciences, Inc., U.S. District Court for the District of Columbia (Case No. 1:05-cv-00706 RMU), and University of Massachusetts and Advanced Cell Technology, Inc. v. Roslin Institute (Edinburgh), Geron Corporation and Exeter Life Sciences, Inc., U.S. District Court for the District of Columbia (Case No. 1:05-cv-00353 RMU).

        Lifeline License.    On May 14, 2004, we entered into three license agreements with Lifeline Cell Technology, formerly known as PacGen Cellco, LLC; the licenses were subsequently amended in August 2005. Pursuant to the license agreements, as amended, we licensed to Lifeline, on an exclusive or non-exclusive basis, as applicable, certain know-how and patent rights for, among other things, the research, development, manufacture and sale of human cells for cell therapy in the treatment of human diabetes and liver diseases, and retinal diseases and retinal degenerative diseases. The license agreements requires milestone payments up to $1.75 million in the aggregate. The agreement requires Lifeline to meet minimum research and development requirements. The licenses continue until expiration of the last valid claim within the licensed patent rights. Either party may terminate the agreements for an uncured breach, and Lifeline may terminate the agreement at any time with 30 days' notice.

        We expect that Lifeline Exclusive License Agreement Number 2, as amended, will be further amended as a result of the Start Settlement and the settlement of University of Massachusetts and Advanced Cell Technology, Inc. v. Roslin Institute (Edinburgh), Geron Corporation and Exeter Life Sciences, Inc., U.S. District Court for the District of Columbia (Case No. 1:05-cv-00706 RMU), and University of Massachusetts and Advanced Cell Technology, Inc. v. Roslin Institute (Edinburgh), Geron Corporation and Exeter Life Sciences, Inc., U.S. District Court for the District of Columbia (Case No. 1:05-cv-00353 RMU).

        Exclusive License Agreement Number 1, as amended, covers patent rights and technology developed by us that are relevant to:

        Lifeline has agreed to pay us royalties ranging from 3% to 10% on net sales of products and services covered by the license, and a minimum royalty fee of $175,000 in the first year, plus, commencing 12 months after the effective date of the agreement, additional minimum royalty fees in the amount of $15,000 at 12 months, $37,500 at 24 months, $60,625 at 36 months, and $75,000 annually

64



thereafter. Lifeline also agreed to pay a license fee in the amount of $225,000 in the form of a Convertible Promissory Note due and payable June 1, 2007, which may be repaid in cash or stock at our election.

        Exclusive License Agreement Number 2, as amended, covers patent rights and technology developed by UMass relevant to:

        Lifeline is required to pay us royalties ranging from 3% to 12% on net sales of products and services covered by the license, and a minimum royalty fee of $100,000 in the first year, plus, commencing 12 months after the effective date of the agreement, additional minimum royalty fees in the amount of $15,000 at 12 months, $30,000 at 24 months, $45,000 at 36 months, and $60,000 annually thereafter. Lifeline also agreed to pay a license fee in the amount of $150,000 in the form of a Convertible Promissory Note due and payable June 1, 2007, which may be repaid in cash or stock at our election.

        We expect that Lifeline Exclusive License Agreement Number 2, as amended, will be further amended as a result of the Start Settlement and the settlement of University of Massachusetts and Advanced Cell Technology, Inc. v. Roslin Institute (Edinburgh), Geron Corporation and Exeter Life Sciences, Inc., U.S. District Court for the District of Columbia (Case No. 1:05-cv-00706 RMU), and University of Massachusetts and Advanced Cell Technology, Inc. v. Roslin Institute (Edinburgh), Geron Corporation and Exeter Life Sciences, Inc., U.S. District Court for the District of Columbia (Case No. 1:05-cv-00353 RMU).

        Exclusive License Agreement Number 3, as amended, covers patent rights and technology developed by Infigen relevant to the research, development, manufacture and sale of human cells for cell therapy in the treatment of therapeutic and diagnostic use in the treatment of human diabetes and liver diseases, and retinal diseases and retinal degenerative diseases. Lifeline is required to pay us royalties equal to 6% of net sales of products and services covered by the license, and a minimum royalty fee of $25,000 in the first year, plus, commencing 12 months after the effective date of the agreement, additional minimum royalty fees in the amount of $7,500 at 12 months, $7,500 at 24 months, $6,875 at 36 months, and $15,000 annually thereafter. Lifeline also agreed to pay a license fee in the amount of $225,000 in the form of a convertible promissory note due and payable June 1, 2007, which may be repaid in cash or stock at our election.

        Start Licensing License.    On August 30, 2006, we entered into a Settlement and License Agreement with UMass and Start Licensing, Inc. See description of this agreement above. Pursuant to this agreement, we granted Start Licensing a worldwide, exclusive, fully paid-up and royalty-free license, with the right to grant sublicenses, to certain patent rights for use in connection with all uses and applications in non-human animals. The agreement was reached in connection with the settlement of the patent interference actions described in Item 8 of our Quarterly Report on Form 10-QSB filed on August 11, 2006 ("Geron-Related Proceedings"). The terms of the agreement also includes an initial payment to us, which has been made, and certain milestone payments. In addition, under the agreement, Start, Geron Corporation and Roslin Institute ("Roslin") each agree not to sue us under certain patent applications owned by Roslin.

65



        Terumo Agreement.    Diacrin, Inc. and Terumo Corporation entered into a development and license agreement on September 4, 2002; the agreement was transferred to Mytogen, Inc. on December 28, 2005. Under the agreement, the parties agreed to collaborate to develop and commercialize products in the field described as autologous skeletal myoblasts for cardiac therapy (and conditionally allogenic skeletal myoblasts for cardiac therapy) in Japan and such other Asian countries as the parties may agree. Pursuant to the agreement, Terumo has an exclusive, royalty-bearing license, with a limited right to grant sublicenses, under certain technology and patent rights controlled by Mytogen; and a non-exclusive, non-royalty bearing right and license to use certain data resulting from clinical trials for products based on the licensed technology and patent rights for purposes of seeking regulatory approvals. The agreement specifies the rights and obligations of the parties with respect to collaboration and development of products covered by the agreement. The agreement also requires Terumo to make certain milestone payments, including the following: two million dollars upon initiation of any clinical trials of any covered product in Japan; two million dollars upon the first filing for regulatory approval of a covered product in Japan; one million dollars upon the first filing for regulatory approval of a covered product in any country other than Japan if the territory is expanded to include countries other than Japan; two million dollars upon the first commercial sale of a covered product in Japan; and one million dollars upon the first commercial sale of a covered product in any country other than Japan if the territory is expanded to include countries other than Japan. Terumo is also required under the agreement to pay royalties in an amount equal to ten percent (10%) of the net sales on covered products.

Nonexclusive Licenses of Intellectual Property by Us

        We have entered into numerous nonexclusive license agreements pursuant to which we have granted non-exclusive rights to various parties to use certain patent rights in defined fields. These licenses generally provide for commercialization of our intellectual property and typically contain minimum royalties, milestones and continuing royalties based upon percentages of revenue.

        California Proposition 71.    In November 2004, California State Proposition 71, referred to as Prop. 71, the California Stem Cell Research and Cures Initiative, was adopted by state-wide referendum. Prop. 71 provides for a state-sponsored program designed to encourage stem cell research in the State of California, and to finance such research with State funds totaling approximately $295 million annually for 10 years beginning in 2005. This initiative creates the California Institute for Regenerative Medicine, which will provide grants, primarily but not exclusively, to academic institutions to advance both ES cell research and adult stem cell research. In 2007, the California Supreme Court refused to hear the appeals related to the previous legal challenges which were dismissed by lower state courts. As a result, the State of California expects to initiate the offering of state bonds to fund the initial grants in late 2007. ES cell research is one of our primary areas of focus. It is unclear whether we are eligible to directly receive Prop. 71 generated funds. However, we intend to apply for any funding that becomes available. We also expect to benefit from collaborations with academic and other institutions eligible for Prop. 71 funding for research in the use of ES cells for various diseases and conditions. ES cell research does not generally qualify for federal funding due to restrictions on embryonic stem cell research. Prop. 71 is specifically targeting research in the embryonic stem cell field. We consider government support to be important confirmation of the quality of our technology, but do not rely on government programs as a significant source of financial support.

        Competition.    The biotechnology industries are characterized by rapidly evolving technology and intense competition. Our competitors include major multinational pharmaceutical companies, specialty biotechnology companies and chemical and medical products companies operating in the fields of regenerative medicine, cell therapy, tissue engineering and tissue regeneration. Many of these companies are well-established and possess technical, research and development, financial and sales and marketing resources significantly greater than ours. In addition, certain smaller biotech companies have

66



formed strategic collaborations, partnerships and other types of joint ventures with larger, well established industry competitors that afford these companies' potential research and development and commercialization advantages. Academic institutions, governmental agencies and other public and private research organizations are also conducting and financing research activities which may produce products directly competitive to those we are developing. Moreover, many of these competitors may be able to obtain patent protection, obtain FDA and other regulatory approvals and begin commercial sales of their products before we do.

        In the general area of cell-based therapies (including both ES cell and autologous cell therapies), we compete with a variety of companies, most of whom are specialty biotechnology companies, such as Geron Corporation, Genzyme Corporation, StemCells, Inc., Aastrom Biosciences, Inc., Viacell, Inc., MG Biotherapeutics, BioHeart, Inc., Baxter Healthcare, Osiris Therapeutics and Cytori. Each of these companies are well-established and have substantial technical and financial resources compared to us. However, as cell-based products are only just emerging as medical therapies, many of our direct competitors are smaller biotechnology and specialty medical products companies. These smaller companies may become significant competitors through rapid evolution of new technologies. Any of these companies could substantially strengthen their competitive position through strategic alliances or collaborative arrangements with large pharmaceutical or biotechnology companies.

        The diseases and medical conditions we are targeting have no effective long-term therapies. Nevertheless, we expect that our technologies and products will compete with a variety of therapeutic products and procedures offered by major pharmaceutical companies. Many pharmaceutical and biotechnology companies are investigating new drugs and therapeutic approaches for the same purposes, which may achieve new efficacy profiles, extend the therapeutic window for such products, alter the prognosis of these diseases, or prevent their onset. We believe that our products, when and if successfully developed, will compete with these products principally on the basis of improved and extended efficacy and safety and their overall economic benefit to the health care system.

        Competition for any stem cell products that we may develop may be in the form of existing and new drugs, other forms of cell transplantation, ablative and simulative procedures, and gene therapy. We believe that some of our competitors are also trying to develop stem and progenitor cell-based technologies. We expect that all of these products will compete with our potential stem cell products based on efficacy, safety, cost and intellectual property positions. We may also face competition from companies that have filed patent applications relating to the use of genetically modified cells to treat disease, disorder or injury. In the event our therapies should require the use of such genetically modified cells, we may be required to seek licenses from these competitors in order to commercialize certain of our proposed products, and such licenses may not be granted.

        If we develop products that receive regulatory approval, they would then have to compete for market acceptance and market share. For certain of our potential products, an important success factor will be the timing of market introduction of competitive products. This timing will be a function of the relative speed with which we and our competitors can develop products, complete the clinical testing and approval processes, and supply commercial quantities of a product to market. These competitive products may also impact the timing of clinical testing and approval processes by limiting the number of clinical investigators and patients available to test our potential products.

        Government Regulation.    Regulation by governmental authorities in the United States and other countries is a significant factor in our research and development and will be a significant factor in the manufacture and marketing of our proposed products. The nature and extent to which such regulation applies to us will vary depending on the nature of any products we may develop. We anticipate that many, if not all, of our products will require regulatory approval by governmental agencies prior to commercialization. In particular, human therapeutic products are subject to rigorous preclinical and clinical testing and other approval procedures of the FDA, and similar regulatory authorities in

67



European and other countries. Various governmental statutes and regulations also govern or influence testing, manufacturing, safety, labeling, storage and recordkeeping related to such products and their marketing. The process of obtaining these approvals and the subsequent compliance with appropriate statutes and regulations require the expenditure of substantial time and money, and there can be no guarantee that approvals will be granted.

        FDA Approval.    The FDA requirements for our potential products to be marketed in the United States include the following five steps:

        Preclinical laboratory and animal tests must be conducted. Preclinical tests include laboratory evaluation of the cells and the formulation intended for use in humans for quality and consistency. In vivo studies are performed in normal animals and specific disease models to assess the potential safety and efficacy of the cell therapy product.

        An investigational new drug application, or IND, must be submitted to the FDA, and the IND must become effective before human clinical trials in the United States may commence. The IND is submitted to the FDA with the preclinical data, a proposed development plan and a proposed protocol for a study in humans. The IND becomes effective 30 days following receipt by the FDA, provided there are no questions, requests for delay or objections from the FDA. If the FDA has questions or concerns, it notifies the sponsor, and the IND will then be on clinical hold until a satisfactory response is made by the sponsor.

        Adequate and well-controlled human clinical trials must be conducted to establish the safety and efficacy of the product. Clinical trials involve the evaluation of a potential product under the supervision of a qualified physician, in accordance with a protocol that details the objectives of the study, the parameters to be used to monitor safety and the efficacy criteria to be evaluated. Each protocol is submitted to the FDA as part of the IND. The protocol for each clinical study must be approved by an independent institutional review board, or IRB, of the institution at which the study is conducted, and the informed consent of all participants must be obtained. The IRB reviews the existing information on the product, considers ethical factors, the safety of human subjects, the potential benefits of the therapy and the possible liability of the institution. The IRB is responsible for ongoing safety assessment of the subjects during the clinical investigation. Clinical development is traditionally conducted in three sequential phases.

        Marketing authorization applications must be submitted to the FDA. The results of the preclinical studies and clinical studies are submitted to the FDA in the form of marketing approval authorization applications.

        The FDA must approve the applications prior to any commercial sale or practice of the technology or product. Biologic product manufacturing establishments located in certain states also may be subject to separate regulatory and licensing requirements. The testing and approval process will require substantial time, effort and expense. The time for approval is affected by a number of factors, including

68



relative risks and benefits demonstrated in clinical trials, the availability of alternative treatments and the severity of the disease. Additional animal studies or clinical trials that may be requested during the FDA review period.

        Our research and development is based largely on the use of human stem and progenitor cells. The FDA has initiated a risk-based approach to regulating human cell, tissue and cellular and tissue-based products and has published current Good Tissue Practice regulations. As part of this approach, the FDA has published final rules for registration of establishments that engage in the recovery, screening, testing, processing, storage or distribution of human cells, tissues, and cellular and tissue-based products, and for the listing of such products. In addition, the FDA has published rules for making suitability and eligibility determinations for donors of cells and tissue and for current good tissue practice for manufacturers using them, which have recently taken effect. We cannot now determine the full effects of this regulatory initiative, including precisely how it may affect the clarity of regulatory obligations and the extent of regulatory burdens associated with our stem cell research and the manufacture and marketing of stem cell products.

        We have completed preclinical testing, two multi-center Phase I clinical trials and a multi-center Phase Ib clinical trial of our myoblast cell transplantation product and we anticipate initiating at least one multi-regional, pivotal Phase II/III study in 2008.

        European and Other Regulatory Approval.    Approval of a product by regulatory authorities comparable to the FDA in Europe and other countries will likely be necessary prior to commencement of marketing a product in any of these countries. The regulatory authorities in each country may impose their own requirements and may refuse to grant approval, or may require additional data before granting approval, even though the relevant product has been approved by the FDA or another authority. The regulatory authorities in the European Union, or EU, and other developed countries have lengthy approval processes for pharmaceutical products. The process for gaining approval in particular countries varies, but is generally similar to the FDA approval process. In Europe, the European Committee for Proprietary Medicinal Products provides a mechanism for EU-member states to exchange information on all aspects of product licensing. The EU has established a European agency for the evaluation of medical products, with both a centralized community procedure and a decentralized procedure, the latter being based on the principle of licensing within one member country followed by mutual recognition by the other member countries.

        Other Regulations.    In addition to safety regulations enforced by the FDA, we are also subject to regulations under the Occupational Safety and Health Act, the Environmental Protection Act, the Toxic Substances Control Act and other present and potential future and federal, state, local, and foreign regulations.

        Outside the United States, we will be subject to regulations that govern the import of drug products from the United States or other manufacturing sites and foreign regulatory requirements governing human clinical trials and marketing approval for our products. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursements vary widely from country to country.

        The United States Congress, several states and foreign countries have considered legislation banning or restricting human application of ES cell-based and nuclear transfer based technologies. No assurance can be given regarding future restrictions or prohibitions that might affect our technology and business. In addition, we cannot assure you that future judicial rulings with respect to nuclear transfer technology or human ES cells will not have the effect of delaying, limiting or preventing the use of nuclear transfer technology or ES cell-based technology or delaying, limiting or preventing the sale, manufacture or use of products or services derived from nuclear transfer technology or ES cell-derived material. Any such legislative or judicial development would harm our ability to generate revenues and operate profitably.

        For additional information about governmental regulations that will affect our planned and intended business operations, see "RISK FACTORS" beginning on page 6 above.

        Employees.    As of September 19, 2007, we had 40 full-time employees, of whom 15 hold Ph.D. or M.D. degrees. 33 employees are directly involved in research and development activities and nine are engaged in business development and administration. We also use the services of numerous outside consultants in business and scientific matters. We believe that we have good relations with our employees and consultants.

MANAGEMENT'S DISCUSSION AND ANALYSIS AND PLAN OF OPERATION

OVERVIEW

        This prospectus contains forward-looking statements that involve risks and uncertainties. We use words such as "may," "assumes," "forecasts," "positions," "predicts," "strategy," "will," "expects," "estimates," "anticipates," "believes," "projects," "intends," "plans," "budgets," "potential," "continue" and variations thereof, and other statements contained in quarterly report, and the exhibits hereto, regarding matters that are not historical facts and are forward-looking statements. Because these statements involve risks and uncertainties, as well as certain assumptions, actual results may differ materially from those expressed or implied by such forward-looking statements. Factors that could cause actual results to differ materially include, but are not limited to risks inherent in: our early stage of development, including a lack of operating history, lack of profitable operations and the need for additional capital; the development and commercialization of largely novel and unproven technologies and products; our ability to protect, maintain, and defend our intellectual property rights: uncertainties regarding our ability to obtain the capital resources needed to continue research and development operations and to conduct research, preclinical development and clinical trials necessary for regulatory approvals; uncertainty regarding the outcome of clinical trials and our overall ability to compete effectively in a highly complex, rapidly developing, capital intensive and competitive industry. See "RISK FACTORS" set forth on page 6 of this prospectus for a more complete discussion of these factors. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date that they are made. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

        The following discussion should be read in conjunction with the consolidated financial statements and notes thereto included herein.

        We are a biotechnology company focused on developing and commercializing human and adult stem cell technology in the emerging field of regenerative medicine.

SIGNIFICANT ACCOUNTING POLICIES

        Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Note 2 of the Notes to Consolidated Financial Statements describes the significant accounting policies used in the preparation of the consolidated financial statements. Certain of these significant accounting policies are considered to be critical accounting policies, as defined below. During the year ended December 31, 2006 we adopted FAS Statement No. 123(R) Share-Based Payment, more fully described below under "Stock-based compensation" and FAS 155 "Accounting for Certain Hybrid Financial Instruments". We applied the accounting proscribed in FAS 155 to account for the 2006 Convertible Debentures described in Note 5—Convertible Debentures 2006. Other than the adoption of these standards, we did not make any significant changes to our accounting policies during the year ended December 31, 2006, as compared to those policies disclosed in the December 31, 2005 consolidated financial statements filed in our Current Report on Form 10-K with the SEC on March 31, 2006.

        A critical accounting policy is defined as one that is both material to the presentation of our financial statements and requires management to make difficult, subjective or complex judgments that could have a material effect on our financial condition and results of operations. Specifically, critical accounting estimates have the following attributes: 1) we are required to make assumptions about matters that are highly uncertain at the time of the estimate; and 2) different estimates we could reasonably have used, or changes in the estimate that are reasonably likely to occur, would have a material effect on our financial condition or results of operations.

71



        Estimates and assumptions about future events and their effects cannot be determined with certainty. We base our estimates on historical experience and on various other assumptions believed to be applicable and reasonable under the circumstances. These estimates may change as new events occur, as additional information is obtained and as our operating environment changes. These changes have historically been minor and have been included in the consolidated financial statements as soon as they became known. Based on a critical assessment of our accounting policies and the underlying judgments and uncertainties affecting the application of those policies, management believes that our consolidated financial statements are fairly stated in accordance with accounting principles generally accepted in the United States, and present a meaningful presentation of our financial condition and results of operations. We believe the following critical accounting policies reflect our more significant estimates and assumptions used in the preparation of our consolidated financial statements:

        Use of Estimates—These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and, accordingly, require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Specifically, our management has estimated variables used to calculate the Black Scholes and binomial lattice model calculations used to value derivative instruments discussed below under "Valuation of Derivative Instruments". In addition, management has estimated the expected economic life and value of our licensed technology, our net operating loss for tax purposes, share-based payments to compensation to employees, directors, consultants and investment banks, the useful lives of our fixed assets and our allowance for bad debts. Actual results could differ from those estimates.

        Fair Value of Financial Instruments—For certain of our financial instruments, including accounts receivable, accounts payable, accrued expenses, interest payable, bank overdraft, advances payable and notes payable, the carrying amounts approximate fair value due to their relatively short maturities.

        Valuation of Derivative Instruments—FAS 133, "Accounting for Derivative Instruments and Hedging Activities" requires bifurcation of embedded derivative instruments and measurement of fair value for accounting purposes. In addition, FAS 155, "Accounting for Certain Hybrid Financial Instruments" requires measurement of fair values of hybrid financial instruments for accounting purposes. We applied the accounting proscribed in FAS 155 to account for the 2006 Convertible Debentures described below in Note 5—Convertible Debentures 2006. In determining the appropriate fair value, the company uses a variety of valuation techniques including Black Scholes models, Binomial Option Pricing models, Standard Put Option Binomial models and net present value of certain penalty amounts. Derivative liabilities are adjusted to reflect fair value at each period end, with any increase or decrease in the fair value being recorded in results of operations as Adjustments to Fair Value of Derivatives. The effects of interactions between embedded derivatives are calculated and accounted for in arriving at the overall fair value of the financial instruments. In addition, the fair values of freestanding derivative instruments such as warrant derivatives are valued using Black Scholes models.

        Cash and Cash Equivalents—Cash equivalents are comprised of certain highly liquid investments with maturity of three months or less when purchased. We maintain our cash in bank deposit accounts, which at times, may exceed federally insured limits. We have not experienced any losses in such account.

        Equipment—We record our equipment at historical cost. We expense maintenance and repairs as incurred. Depreciation is provided for by the straight-line method over three to six years. In the case of certain assets acquired under Capital Leases, the assets are recorded net of imputed interest, based upon the net present value of future payments.

        Revenue Recognition—Our revenues are generated from license and research agreements with collaborators. Licensing revenue is recognized on a straight line basis over the shorter of the life of the license and the estimated economic life of the patents related to the license. Deferred revenue

72



represents the portion of the license and other payments received that has not been earned. Costs associated with the license revenue are deferred and recognized over the same term as the revenue. Reimbursements of research expense pursuant to grants are recorded as a reduction of research and development expense once the reimbursements are approved and the company is assured of collectibility.

        Intangible and Long-Lived Assets—We follow FAS No. 144, "Accounting for Impairment of Disposal of Long-Lived Assets," which established a "primary asset" approach to determine the cash flow estimation period for a group of assets and liabilities that represents the unit of accounting for a long-lived asset to be held and used. Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell. During the period ended December 31, 2006 no impairment losses were recognized.

        Research and Development Costs—Research and development costs consist of expenditures for the research and development of patents and technology, which are not capitalizable. Our research and development costs consist mainly of payroll and payroll related expenses, research supplies and research grants. Reimbursements of research expense pursuant to grants are recorded in the period during which collection of the reimbursement becomes assured, because the reimbursements are subject to approval. Research and development costs are expensed as incurred.

        Deferred Issuance Costs—Payments, either in cash or share-based payments, made in connection with the sale of debentures are recorded as deferred debt issuance costs and amortized using the effective interest method over the lives of the related debentures. The weighted average amortization period for deferred debt issuance costs is 36 months.

        Stock Based Compensation—At December 31, 2006, we had two stock-based employee compensation plans, which are described more fully in Note 11—Options Outstanding.

        Prior to the January 1, 2006 adoption of the FAS No. 123(R), "Share-Based Payment," the Company accounted for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations. Because the stock option grant price equaled the market price on the date of grant, no compensation expense was recognized by the Company for stock-based compensation. As permitted by SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123") stock-based compensation was included as a pro forma disclosure in the notes to the consolidated financial statements.

        Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS 123R, using the modified prospective transition method. Under this transition method, stock-based compensation expense is recognized in the consolidated financial statements for granted, modified or settled stock options. Results for prior periods have not been restated, as provided for under the modified prospective method.

        Prior to the adoption of SFAS 123R, the Company presented all tax benefits resulting from the exercise of stock options as operating cash inflows in the consolidated statements of cash flows, in accordance with the provisions of the Emerging Issues Task Force ("EITF") Issue No. 00-15, "Classification in the Statement of Cash Flows of the Income Tax Benefit Received by a Company upon Exercise of a Nonqualified Employee Stock Option." SFAS 123R requires the benefits of tax deductions in excess of the compensation cost recognized for those options to be classified as financing cash inflows rather than operating cash inflows, on a prospective basis. The impact of this change was not material to the Company.

RESULTS OF OPERATIONS

Fiscal Years ended December 31, 2006 and December 31, 2005

Revenues

        Revenues for the twelve months ended December 31, 2006 and December 31, 2005 were approximately $441,000 and $395,000 rsespectively. These amounts relate primarily to license fees and royalties collected that are being amortized over the period of the license granted. The increase in revenue in the current period was due to increased revenue from new licenses issued in the period.

Research and Development Expenses and Grant Reimbursements

        Research and development expenses for the twelve months ended December 31, 2006 and 2005 were approximately $9,027,000 and $2,606,000, respectively. During the twelve months ended December 31, 2006, the Company has significantly increased scientific research and has allocated a much greater portion of expenditure and focus on research and development activity than had previously been the case. Additional expenditure in this area includes scientific payroll and payroll related expenses, facilities costs and scientific supplies as well as investment in the infrastructure needed to support this greater scientific activity.

        Our research and development expenses for the periods indicated consist primarily of costs associated with basic and pre-clinical research exclusively in the field of human stem cell therapies and regenerative medicine, with focus on development of our technologies in cellular reprogramming, reduced complexity applications, and stem cell differentiation. These expenses represent both pre-clinical development costs and costs associated with non-clinical support activities such as quality control and regulatory processes. The cost of our research and development personnel is the most significant category of expense; however, we also incur expenses with third parties, including license agreements, sponsored research programs and consulting expenses. On a forward-looking basis, our expenses will also include the myoblast clinical program.

        We do not segregate research and development costs by project because our research is focused exclusively on human stem cell therapies as a unitary field of study. Although we have three principal areas of focus for our research, these areas are completely intertwined and have not yet matured to the point where they are separate and distinct projects. The intellectual property, scientists and other resources dedicated to these efforts are not separately allocated to individual projects, but rather are conducting our research on an integrated basis.

        We expect that research and development expenses will continue to increase in the foreseeable future as we add personnel, expand our pre-clinical research, begin clinical trial activities, and increase our regulatory compliance capabilities. The amount of these increases is difficult to predict due to the uncertainty inherent in the timing and extent of progress in our research programs, and initiation of clinical trials. In addition, the results from our basic research and pre-clinical trials, as well as the results of trials of similar therapeutics under development by others, will influence the number, size and duration of planned and unplanned trials. As our research efforts mature, we will continue to review the direction of our research based on an assessment of the value of possible commercial applications emerging from these efforts. Based on this continuing review, we expect to establish discrete research programs and evaluate the cost and potential for cash inflows from commercializing products, partnering with others in the biotechnology or pharmaceutical industry, or licensing the technologies associated with these programs to third parties.

        We believe that it is not possible at this stage to provide a meaningful estimate of the total cost to complete our ongoing projects and bring any proposed products to market. The use of human embryonic stem cells and adult stem cells as a therapy is an emerging area of medicine, and it is not known what clinical trials will be required by the FDA in order to gain marketing approval. Costs to

74



complete could vary substantially depending upon the projects selected for development, the number of clinical trials required and the number of patients needed for each study. It is possible that the completion of these studies could be delayed for a variety of reasons, including difficulties in enrolling patients, delays in manufacturing, incomplete or inconsistent data from the pre-clinical or clinical trials, and difficulties evaluating the trial results. Any delay in completion of a trial would increase the cost of that trial, which would harm our results of operations. Due to these uncertainties, we cannot reasonably estimate the size, nature nor timing of the costs to complete, or the amount or timing of the net cash inflows from our current activities. Until we obtain further relevant pre-clinical and clinical data, we will not be able to estimate our future expenses related to these programs or when, if ever, and to what extent we will receive cash inflows from resulting products.

        Grant reimbursements for the twelve months ended December 31, 2006 and 2005 were approximately $369,000 and $742,000, respectively. These amounts represent approved reimbursements pursuant the grant from the National Institutes of Science and Technology. This grant expired in May 2006.

General and Administrative Expenses

        General and administrative expenses for the twelve months ended December 31, 2006 and December 31, 2005 were approximately $9,152,000 and $9,304,000, respectively. The level of spending on general and administrative expenses has remained consistent during the periods as we seek to hold these costs at current levels whilst increasing spending on research and development.

Other Income/(Expense)

        Other income/(expense) for the twelve months ended December 31, 2006 and December 31, 2005 were approximately ($1,037,000) and $1,562,000, respectively. The increase in other expense in the twelve months ended December 31, 2006, compared to other income in the prior periods, relates primarily to increased Interest Expense, which relates primarily to the amortization of discounts on Convertible Debentures and embedded derivatives and to charges related to issuance of Convertible Debentures and repricing and issuance of warrants. This is partially offset by the increased adjustments to the fair value of derivatives during the period.

Net Loss

        Net loss for the twelve months ended December 31, 2006 and December 31, 2005 was approximately $18,720,000 and $9,394,000, respectively. The increased loss in the current periods is the result of increased research and development expenses, and to the increase in other expenses.

Six Months ended June 30, 2006 and June 30, 2005

Three and six months ended June 30, 2007 and 2006

Revenues

        Revenues for the three and six months ended June 30, 2007 and 2006 were approximately $274,000, $399,000, $121,000, and $204,000 respectively. These amounts relate primarily to license fees and royalties collected that are being amortized over the period of the license granted. The increase in revenue in current periods was due to new licenses being granted.

Research and Development Expenses and Grant Reimbursements

        Research and development expenses for the three and six months ended June 30, 2007 and 2006 were approximately $2,829,000, $6,478,000, $2,617,000, and $4,426,000 respectively. The increase in expenses in the current periods, which consist mainly of facility costs, payroll and payroll related

75



expenses, research supplies and costs incurred in connection with specific research grants, relate principally to increased staffing and spending for scientific research.

        Our research and development expenses for the periods indicated consist primarily of costs associated with basic and pre-clinical research exclusively in the field of human stem cell therapies and regenerative medicine, with focus on development of our technologies in cellular reprogramming, reduced complexity applications, and stem cell differentiation. These expenses represent both pre-clinical development costs and costs associated with non-clinical support activities such as quality control and regulatory processes. The cost of our research and development personnel is the most significant category of expense; however, we also incur expenses with third parties, including license agreements, sponsored research programs and consulting expenses. On a forward-looking basis our costs will also include the myoblast clinical program.

        We do not segregate research and development costs by project because our research is focused exclusively on human stem cell therapies as a unitary field of study.

        Grant reimbursements for the three and six months ended June 30, 2007 and 2006 were approximately $9,600, $67,000, $163,000 and $364,000 respectively. The 2006 amounts represent approved reimbursements pursuant the grant from National Institutes of Science and Technology. This grant expired in May 2006. The 2007 grant amount is from the Small Business Technology Transfer Program.

76



General and Administrative Expenses

        General and administrative expenses for the three and six months ended June 30, 2007 and 2006 were approximately $1,246,000, $2,987,000, $1,878,000 and $4,508,000 respectively. Expenses for the three month period versus the same period last year have decreased primarily as a result of decreased general and administrative infrastructure costs and legal fees.

Other Income (Expense)

        Other income (expense) for the three and six months ended June 30, 2007 and 2006 were approximately $15,071,000, $409,000, $13,599,000 and $22,628,000, respectively. The increase in other expense in the three months ended June 30, 2007, compared to other income in the prior periods, relates primarily to adjustments to fair value of derivatives related to the Convertible Debenture financing and the Charges related to issuance of Convertible Debentures. The increase in interest expense in the six months ended June 2007, compared to interest expense in the prior periods relates primarily to interest recorded in connection with the convertible debentures.

Net Income (Loss)

        Net income (loss) for the three and six months ended June 30, 2007 and 2006 was approximately $11,169,000, ($8,762,000), $9,295,000, and $14,108,000 respectively. The decrease in loss in the current period is the result of changes to the fair value of derivatives, interest charges related to convertible debentures and charges related to issuance of Convertible Debentures along with increased general and administrative and research and development expenses, as well as decreased grant reimbursements.

RECENT ACCOUNTING PRONOUNCEMENTS

        On February 15, 2007, the Financial Accounting Standards Board, or FASB, issued FAS No. 159, "The Fair Value Option for Financial Assets and Liabilities—Including an Amendment of FAS 115." This standard permits an entity to choose to measure many financial instruments and certain other items at fair value. This option is available to all entities. Most of the provisions in FAS 159 are elective; however, an amendment to FAS 115 "Accounting for Certain Investments in Debt and Equity Securities" applies to all entities with available for sale or trading securities. Some requirements apply differently to entities that do not report net income. FAS 159 is effective as of the beginning of an entities first fiscal year that begins after November 15, 2007. Early adoption is permitted as of the beginning of the previous fiscal year provided that the entity makes that choice in the first 120 days of that fiscal year and also elects to apply the provisions of FAS 157 "Fair Value Measurements." We will adopt FAS 159 beginning January 1, 2008 and we are currently evaluating the potential impact the adoption of this pronouncement will have on our financial statements.

        In December 2006, the FASB posted FASB Staff Position, or FSP 00-19-2, "Accounting for Registration Payment Arrangements." This FSP specifies that the contingent obligation to make future payments or otherwise transfer consideration under a registration payment arrangement, whether issued as a separate agreement or included as a provision of a financial instrument or other agreement should be separately recognized and measured in accordance with FAS No. 5, "Accounting for Contingencies." This FSP further clarifies that a financial instrument subject to a registration payment arrangement should be accounted for in accordance with other applicable GAAP without regard to the contingent obligation to transfer consideration pursuant to the registration payment arrangement. This FSP is effective immediately for registration payment arrangements and financial instruments subject to those arrangements that were entered into or modified subsequent to December 15, 2006. For registration payment arrangements and financial instruments subject to those arrangements that were entered into prior to December 15, 2006, the FSP is effective for fiscal years beginning after December 15, 2006, and interim periods within those fiscal years. We will adopt FSP 00-19-2 beginning January 1, 2008 and

77



we are currently evaluating the potential impact the adoption of this pronouncement will have on our financial statements.

        In September 2006, the Financial Accounting Standards Board, or FASB, issued FAS No. 157, Fair Value Measurements, or FAS 157, which provides guidance on how to measure assets and liabilities that use fair value. This Statement clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. FAS 157 will apply whenever another generally accepted accounting principle requires, or permits, assets or liabilities to be measure at fair value but does not expand the use of fair value to any new circumstances. This statement will also require additional disclosures in both annual and quarterly reports. FAS 157 is effective for fiscal years beginning after November 2007, and will be adopted by us beginning January 1, 2008. We are currently evaluating the potential impact this statement may have on our financial statements, but do not believe the impact of adoption will be material.

        In September 2006, the SEC staff issued Staff Accounting Bulletin, or SAB, No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, or SAB 108. SAB 108 provides guidance on the consideration of the effects of prior year misstatements in quantifying current year misstatements for the purpose of determining whether the current year's financial statements are materially misstated. SAB 108 is effective for fiscal years ending after November 15, 2006. We will initially apply the provisions of SAB 108 in connection with the preparation of our annual financial statements for the year ending December 31, 2006. We have evaluated the potential impact that SAB 108 may have on our financial statements and do not believe the impact of the application of this guidance will be material.

        In September 2006, the FASB issued FAS No. 158, Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans, or FAS 158. This Statement requires companies to recognize in their statement of financial position an asset for a plan's overfunded status or a liability for a plan's underfunded status and to measure a plan's assets and its obligations that determine its funded status as of the end of the company's fiscal year. Additionally, FAS 158 requires companies to recognize changes in the funded status of a defined benefit postretirement plan in the year that the changes occur and those changes will be reported in comprehensive income. The provisions of FAS 158 are effective as of the end of fiscal year 2006 and we are currently in the process of quantifying the impact to the financial statements.

        In July 2006, the FASB issued Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 09, Accounting for Income Taxes ("FIN No. 48"). This interpretation creates a single model to address uncertainty in tax positions. FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. The interpretation also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for years beginning after December 15, 2006. Management of the Company is evaluating the impact of this pronouncement, but does not anticipate that it will have a significant impact on its financial statements.

        In February 2006, the FASB issued FAS No. 155, Accounting for Certain Hybrid Instruments. This standard amends the guidance in FASB Statements No. 133, Accounting for Derivative Instruments and Hedging Activities, and No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities. Statement 155 allows financial instruments that have embedded derivatives to be accounted for as a whole (eliminating the need to bifurcate the derivative from its host) if the holder elects to account for the whole instrument on a fair value basis. The Company has adopted FAS 155 and applies it to all relevant financing transactions from the date of adoption.

        In September 2005, the EITF reached a consensus on Issue 05-8, "Income Tax Consequences of Issuing Convertible Debt with a Beneficial Conversion Feature." EITF Issues No. 98-5, "Accounting for Convertible Securities with Beneficial Conversion Features or Contingently Adjustable Conversion Ratios," and No. 00-27, "Application of Issue No. 98-5 to Certain Convertible Instruments," provide guidance on how companies should bifurcate convertible debt issued with a beneficial conversion feature into a liability and an equity component. For income tax purposes, such an instrument is only recorded as a liability. A question has been raised as to whether a basis difference results from the issuance of convertible debt with a beneficial conversion feature and, if so, whether the basis difference is a temporary difference. We do not expect the provisions of this consensus to have a material impact on our financial position, results of operations or cash flows.

        In September 2005, the EITF discussed Issue 05-4, The Effect of a Liquidated Damages Clause on a Freestanding Instrument Subject to EITF Issue No. 00-19, "Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock." The Effect of a Liquidated Damages Clause on a Freestanding Financial Instrument Subject to EITF Issue No. 00-19, "Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock." Issuance of a registration rights agreement with a liquidated damages clause is common when equity instruments, stock purchase warrants, and financial instruments that are convertible into equity securities are issued. The agreement requires the issuer to use its "best efforts" to file a registration statement for the resale of the equity instruments or the shares of stock underlying the stock purchase warrant or convertible financial instrument and have it declared effective by the end of a specified grace period. The issuer may also be required to maintain the effectiveness of the registration statement for a period of time or pay a liquidated damage penalty to the investor each month until the registration statement is declared effective. Given the potential significance of the penalty, a question arises as to the effect, if any, this feature has on the related financial instruments if they are subject to the scope of Issue 00-19. The company took the provisions of this issue into account in their accounting for the period.

        In September 2005, the EITF reached a consensus on Issue 05-7, "Accounting for Modifications to Conversion Options Embedded in Debt Securities and Related Issues." EITF Issue No. 96-19, "Debtor's Accounting for a Modification or Exchange of Debt Instruments," provides guidance on whether modifications of debt result in an extinguishment of that debt. In certain situations, companies may change the terms of a conversion option as part of a debt modification, which may result in the following circumstances: (a) the change in the conversion option's terms causes the fair value of the conversion option to change but does not result in the modification meeting the condition in Issue 96-19 that would require the modification to be accounted for as an extinguishment of debt, and (b) the change in the conversion option's terms did not result in separate accounting for the conversion option under Statement 133. When both of these circumstances exist, questions have arisen regarding whether (a) the modification to the conversion option, which changes its fair value, should affect subsequent interest expense recognition related to the debt and (b) a beneficial conversion feature related to a debt modification should be recognized by the borrower if the modification increases the intrinsic value of the debt. We do not expect the provisions of this consensus to have a material impact on our financial position, results of operations or cash flows.

        In June 2005, the EITF reached a consensus on Issue 05-2, "The Meaning of "Conventional Convertible Debt Instrument" in EITF Issue 00-19. Paragraph 4 of Issue 00-19 states that "the requirements of paragraphs 12-32 of this issue do not apply if the hybrid contract is a conventional convertible debt instrument in which the holder may only realize the value of the conversion option by exercising the option and receiving the entire proceeds in a fixed number of shares or the equivalent amount of cash (at the discretion of the issuer)". The term "conventional convertible debt instrument" is not defined in Issue 00-19 and, as a result, questions have arisen regarding when a convertible debt instrument should be considered "conventional" for purposes of Issue 00-19. A question has also arisen

79



related to whether conventional convertible preferred stock should be treated similar to conventional convertible debt. We do not expect the provisions of this consensus to have a material impact on our financial position, results of operations or cash flows.

        In June 2005, the EITF reached a consensus on Issue 05-6, Determining the Amortization Period for Leasehold Improvements, which requires that leasehold improvements acquired in a business combination or purchased subsequent to the inception of a lease be amortized over the lesser of the useful life of the assets or a term that includes renewals that are reasonably assured at the date of the business combination or purchase. EITF 05-6 is effective for periods beginning after July 1, 2005. We do not expect the provisions of this consensus to have a material impact on our financial position, results of operations or cash flows.

        In March 2005, the FASB issued FASB Interpretation No. 47, "Accounting for Conditional Asset Retirement Obligations" ("FIN 47"). FIN 47 provides guidance relating to the identification of and financial reporting for legal obligations to perform an asset retirement activity. The Interpretation requires recognition of a liability for the fair value of a conditional asset retirement obligation when incurred if the liability's fair value can be reasonably estimated. FIN 47 also defines when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. The provision is effective no later than the end of fiscal years ending after December 15, 2005. The Company will adopt FIN 47 beginning the first quarter of fiscal year 2006 and does not believe the adoption will have a material impact on its consolidated financial position or results of operations or cash flows.

        In May 2005, the FASB issued FAS No. 154, "Accounting Changes and Error Corrections—a replacement of APB Opinion No. 20 and FAB Statement No. 3". FAS No. 154 requires retrospective application to prior periods' financial statements of changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. FAS No. 154 also requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle, such as a change in nondiscretionary profit-sharing payments resulting from an accounting change, should be recognized in the period of the accounting change. FAS No. 154 also requires that a change in depreciation, amortization or depletion method for long-lived, non-financial assets be accounted for as a change in accounting estimate effected by a change in accounting principle. FAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. Early adoption is permitted for accounting changes and corrections of errors made in fiscal years beginning after the date this Statement is issued. Management does not expect the implementation of this new standard to have a material impact on our financial position, results of operations and cash flows.

        In March 2005, the SEC released Staff Accounting Bulletin No. 107, "Share-Based Payment"("SAB 107"), which provides interpretive guidance related to the interaction between FAS 123(R) and certain SEC rules and regulations. It also provides the SEC staff's views regarding valuation of share-based payment arrangements. In April 2005, the SEC amended the compliance dates for FAS 123(R), to allow companies to implement the standard at the beginning of their next fiscal year, instead of the next reporting period beginning after June 15, 2005. Management is currently evaluating the impact SAB 107 will have on our consolidated financial statements.

LIQUIDITY AND CAPITAL RESOURCES

        We are financing our operations primarily with $10,000,000 of proceeds from the secured convertible debentures issued in August 2007 and described in our Current Report on Form 8-K filed with the Securities and Exchange Commission on September 7, 2007. To a substantially lesser degree,

80



financing of our operations is provided through grant funding, payments received under license agreements, and interest earned on cash and cash equivalents.

        With the exception of 2002, when we sold certain assets of a subsidiary resulting in a gain for the year, we have incurred substantial net losses each year since inception as a result of research and development and general and administrative expenses in support of our operations. We anticipate incurring substantial net losses in the future.

        Cash and cash equivalents at June 30, 2007 and December 31, 2006 were approximately $770,000 and $8,689,000, respectively. The decrease in the current period is primarily the result of operational cash expenditures.

        Our cash and cash equivalents are limited. We expect to require substantial additional funding. Our future cash requirements will depend on many factors, including the pace and scope of our research and development programs, the costs involved in filing, prosecuting, maintaining and enforcing patents and other costs associated with commercializing our potential products. We intend to seek additional funding primarily through public or private financing transactions, and, to a lesser degree, new licensing or scientific collaborations, grants from governmental or other institutions, and other related transactions. If we are unable to raise additional funds, we will be forced to either scale back our business efforts or curtail our business activities entirely. We anticipate that our available cash and expected income will be sufficient to finance most of our current activities for at least twelve months from the date of the financial statements, although certain of these activities and related personnel may need to be reduced. We cannot assure you that public or private financing or grants will be available on acceptable terms, if at all. Several factors will affect our ability to raise additional funding, including, but not limited to, the volatility of our Common Stock.

81



PROPERTIES

        Our headquarters are located at 1201 Harbor Bay Parkway, Alameda, California 94502. Our facilities consist of approximately 15,250 square feet of laboratory and office space. Our sublease for the California facility expires on May 31, 2008. We also lease approximately 14,000 square foot of office and laboratory facilities at 381 Plantation Street in Worcester, MA, which, together with the California facility, provides us the capability of producing necessary quantities of materials sufficient to support our research. We have the Worcester facility under an eight year sub-lease which expires on April 30, 2010. In addition, we lease approximately 3,000 square feet of corporate office space at 11100 Santa Monica Boulevard in Los Angeles, CA 90025. We also lease approximately 25,000 square foot of office and laboratory facilities at 79/96 Thirteenth Street, Charlestown, Massachusetts, which provides us the capability of pursuing our Mytoblast Program. We have the Charlestown facility under a five year lease which expires on or about October 10, 2011. We do not own any real estate.

82



CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

        Except as described below, none of the following parties has, since our date of incorporation, had any material interest, direct or indirect, in any transaction with us or in any presently proposed transaction that has or will materially affect us, other than as noted in this section:

Transactions with ACT Group

        On July 12, 2002, we issued a promissory note with a face amount of $1,000,000, referred to as the Group Note, to our majority stockholder, ACT Group, as a repayment of advances received from ACT Group. The Group Note was extinguished in full in connection with the execution of the Aronson settlement agreement. As a condition to our entering into the Aronson settlement agreement, we entered into an agreement with ACT Group, referred to as the Group Agreement, compensating us for the obligations we incurred under the Aronson settlement agreement, which extinguished in full ACT Group's obligations and indebtedness to the plaintiffs in the Aronson matter, and resolving certain disputes with respect to amounts due to and from us and ACT Group.

        Pursuant to the Group Agreement, in consideration for our entering into the Aronson settlement agreement, the following was agreed to by ACT Group and us:

Bridge Loan Transaction

        During the period August through October 2004, we issued promissory notes aggregating $500,000 face value for cash proceeds of $450,000 and the assumption of $50,000 of debt owed by our parent to the following related parties, in addition to other unrelated parties: Anthem Venture Management, LLC in the amount of $100,000 and Gregory A. Bonfiglio in the amount of $50,000. The notes bear interest at 10% per year.

        As additional consideration for the purchase of the notes, on November 26, 2004, we granted warrants to certain related parties who were note holders entitling them to purchase shares of our common stock at an exercise price of $0.05. Warrants were issued to Anthem Venture Management, LLC for 100,000 shares and to Gregory A. Bonfiglio for 50,000 shares that are exercisable on or after February 1, 2006 and expire February 1, 2008.

        During the first quarter of 2005, the $500,000 of notes, plus accrued interest of $23,708, were converted into investment units consisting of 616,124 shares of common stock, plus 308,063 common stock purchase warrants, exercisable at $1.27 per share.

83


Private Equity Financing

        On November 26, 2004, in connection with the early release from escrow of funds related to our private equity financing, we granted to Andwell, LLC, a company affiliated with our Chief Executive Officer, William M. Caldwell, IV, warrants to purchase 250,000 shares of our common stock at an exercise price of $0.05 per share. The warrants are exercisable for twenty four months from the date of issuance.

        On September 15, 2005, in connection with the Securities Purchase Agreement dated September 15, 2005, Anthem Ventures Fund, L.P. purchased convertible debentures with a principal amount of $1,255,000, convertible into 545,652 shares of common stock. In connection with the purchase of the debentures, we issued Anthem Ventures Fund, L.P. warrants to purchase 272,826 shares of our common stock at an exercise price of $2.53 per share. As of December 31, 2006, Anthem Ventures Fund, L.P. was the beneficial owner of 11.2% of our outstanding common stock.

        On September 15, 2005, in connection with the Securities Purchase Agreement dated September 15, 2005, The Shapiro Family Trust Dated September 29, 1989, purchased convertible debentures with a principal amount of $251,000, convertible into 109,130 shares of common stock. In connection with the purchase of the debentures, we issued The Shapiro Family Trust Dated September 29, 1989, warrants to purchase 54,565 shares of our common stock at an exercise price of $2.53 per share.

Other Agreements

        We entered into that certain Nomination Agreement dated September 20, 2007, with Anthem Ventures Fund, LP. The Company previously agreed to a nomination agreement with Anthem in August 2005. Anthem shall have the right to designate in its sole discretion, and the company shall nominate and appoint, a director to the company's board of directors.

Related Party Transactions Prior to Merger and Complete Change of Business

        In our 10-KSB for the year ended December 31, 2003, we reported that an officer/shareholder of ours had made advances to us and had directly paid expenses on behalf of us in the amount of $6,173, as of December 31, 2003. Because these advances related to our business prior to the merger and complete change of business on January 31, 2005, we do not believe that they are relevant or material to our current business.

Board Determination of Independence

        The company complies with the standards of "independence" prescribed by rules set forth by the National Association of Securities Dealers ("NASD"). Accordingly, a director will only qualify as an "independent director" if, in the opinion of our Board of Directors, that person does not have a material relationship with our company which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. A director who is, or at any time during the past three years, was employed by the company or by any parent or subsidiary of the company, shall not be considered independent. Accordingly, Dr. Alan Shapiro, Dr. Alan Walton, and Dr. Erkki Ruoslahti meet the definition of "independent director" under Rule 4200(A)(15) of the NASD Manual; Dr. West and Mr. Caldwell do not.

MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

Market Information

        Our common stock is quoted on the OTC Bulletin Board under the symbol "ACTC." For the periods indicated, the following table sets forth the high and low bid prices per share of our common stock. These prices represent inter-dealer quotations without retail markup, markdown, or commission and may not necessarily represent actual transactions. We have not provided price information prior to fiscal year 2005, in so far as we believe that the trading of our common stock prior to the merger is not material due to the fact that we effected a complete change of business operations following the merger.

Fiscal Year 2005

  High Bid
  Low Bid
First Quarter   $ 7.00   $ 1.90
Second Quarter   $ 4.50   $ 2.65
Third Quarter   $ 2.90   $ 2.00
Fourth Quarter   $ 2.95   $ 1.84
Fiscal Year 2006

Fiscal Year 2007

Second Quarter   $ 1.10   $ 0.32

        Trades of our common stock are subject to Rule 15g-9 of the Securities and Exchange Commission, known as the Penny Stock Rule. This rule imposes requirements on broker/dealers who sell securities subject to the rule to persons other than established customers and accredited investors. For transactions covered by the rule, brokers/dealers must make a special suitability determination for purchasers of the securities and receive the purchaser's written agreement to the transaction prior to sale. The Securities and Exchange Commission also has rules that regulate broker/dealer practices in connection with transactions in "penny stocks." Penny stocks generally are equity securities with a price of less than $5.00, other than securities registered on certain national securities exchanges or quoted on the NASDAQ system, provided that current price and volume information with respect to transactions in that security is provided by the exchange or system. The Penny Stock Rules requires a broker/dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document prepared by the Commission that provides information about penny stocks and the nature and level of risks in the penny stock market. The broker/dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker/dealer and its salesperson in the transaction, and monthly account statements showing the market value of each penny stock held in the customer's account. The bid and offer quotations, and the broker/dealer and salesperson compensation information, must be given to the customer orally or in writing prior to effecting the transaction and must be given to the customer in writing before or with the customer's confirmation. These disclosure requirements have the effect of reducing the level of trading activity in the secondary market for our common stock. As a result of these rules, investors may find it difficult to sell their shares.

Holders

        As of September 6, 2007, there were approximately 3000 record owners of our common stock.

87



Dividends

        We have never paid cash dividends and have no plans to do so in the foreseeable future. Our future dividend policy will be determined by our board of directors and will depend upon a number of factors, including our financial condition and performance, our cash needs and expansion plans, income tax consequences, and the restrictions that applicable laws, our current preferred stock instruments, and our future credit arrangements may then impose.

        Currently under Delaware law, unless further restricted in its certificate of incorporation, a corporation may declare and pay dividends out of surplus, or if no surplus exists, out of net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year (provided that the amount of capital of the corporation is not less than the aggregate amount of the capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets).

With respect to the company's Compensation Committee and the company's Nominating and Corporate Governance Committee, the Chair receives a payment of $1,125 per meeting and the regular members receive $750 per meeting. Each director is entitled to receive payment of the directors' fees in the form of shares of the company's Common Stock valued at 150% of the actual directors' fees due and payable.

CORPORATE GOVERNANCE

General

        We believe that good corporate governance is important to ensure that Advanced Cell Technology, Inc. is managed for the long-term benefit of our stockholders. This section describes key corporate governance practices that we have adopted.

Board of Directors Meetings and Attendance

        The Board of Directors has responsibility for establishing broad corporate policies and reviewing our overall performance rather than day-to-day operations. The primary responsibility of our Board of Directors is to oversee the management of our company and, in doing so, serve the best interests of the company and our stockholders. The Board of Directors selects, evaluates and provides for the succession of executive officers and, subject to stockholder election, directors. It reviews and approves corporate objectives and strategies, and evaluates significant policies and proposed major commitments of corporate resources. Our Board of Directors also participates in decisions that have a potential major economic impact on our company. Management keeps the directors informed of company activity through regular communication, including written reports and presentations at Board of Directors and committee meetings.

        We have no formal policy regarding director attendance at the annual meeting of stockholders, although all directors are expected to attend the annual meeting of stockholders if they are able to do so. The Board of Directors held eight meetings in 2006, three of which were telephonic. All five board members were present, either by person or on the telephone in the case of the telephonic meetings, at all eight meetings.

93



Board Committees

        Our Board of Directors has established an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The members of each committee are appointed by our Board of Directors, upon recommendation of the Nominating Committee, and serve one-year terms. Each of these committees operates under a charter that has been approved by the Board of Directors. The charter for each committee is available on our website. The Audit Committee met four times during 2006. The Compensation Committee met four times during 2006. The Nominating Committee did not meet during 2006.

        The Audit Committee's responsibilities include:

        Dr. Shapiro, Dr. Walton, and Dr. Ruoslahti serve on our Audit Committee. Dr. Shapiro serves as chair of the Audit Committee. The Board of Directors has determined that Dr. Shapiro is an "audit committee financial expert" as defined in Item 401(e) of Regulation S-B. The board has determined that Dr. Shapiro meets the additional independence requirements of Rule 10A-3 under the Securities Exchange Act of 1934.

        The Compensation Committee's responsibilities include:

        The members of the Compensation Committee are Dr. Shapiro, Dr. Walton, Dr. Ruoslahti and William M. Caldwell, IV.

        The Nominating Committee's responsibilities include:

94


        The members of the Nominating Committee are Dr. Shapiro, Dr. Walton, and Dr. Ruoslahti.

Director Candidates

        The process followed by the Nominating Committee to identify and evaluate director candidates includes requests to board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the Nominating Committee and the Board.

        In considering whether to recommend any particular candidate for inclusion in the Board's slate of recommended director nominees, the Nominating Committee applies certain criteria, including


        The Nominating Committee does not assign specific weights to particular criteria and no particular criterion is a prerequisite for each prospective nominee. We believe that the backgrounds and qualifications of our directors, considered as a group, should provide a significant breadth of experience, knowledge and abilities that will allow our Board to fulfill its responsibilities.

        The Nominating Committee will consider director candidates recommended by stockholders or groups of stockholders who have owned more than 5% of our common stock for at least a year as of the date the recommendation is made. Stockholders may recommend individuals to the Nominating Committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials and a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more than 5% of our common stock for at least a year as of the date such recommendation is made, to the Nominating Committee, c/o Corporate Secretary, Advanced Cell Technology, Inc., 1201 Harbor Bay Parkway, Alameda, CA 94502. Assuming that appropriate biographical and background material have been provided on a timely basis, the Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

Communicating with the Directors

        The Board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. The chair of the Audit Committee is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the other directors as he considers appropriate.

        Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that the chair of the Audit Committee considers to be important for the directors to know. In general, communications relating to corporate governance and corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs,

95



personal grievances and matters as to which we tend to receive repetitive or duplicative communications.

        Stockholders who wish to send communications on any topic to the board should address such communications to the Board of Directors, c/o Corporate Secretary, Advanced Cell Technology, Inc., 1201 Harbor Bay Parkway, Alameda, CA 94502. You should indicate on your correspondence that you are an Advanced Cell Technology, Inc. stockholder.

        Anyone may express concerns regarding questionable accounting or auditing matters or complaints regarding accounting, internal accounting controls or auditing matters to the Audit Committee by calling (508) 756-1212. Messages to the Audit Committee will be received by the chair of the Audit Committee and our Corporate Secretary. You may report your concern anonymously or confidentially.

Section 16(a) Beneficial Ownership Reporting Compliance

        Section 16(a) of the Exchange Act requires the company's directors, executive officers and persons who own more than 10% of the company's stock (collectively, "Reporting Persons") to file with the SEC initial reports of ownership and changes in ownership of the company's common stock. Reporting Persons are required by SEC regulations to furnish the company with copies of all Section 16(a) reports they file. To the company's knowledge, based solely on its review of the copies of such reports received or written representations from certain Reporting Persons that no other reports were required, the company believes that during its fiscal year ended December 31, 2006, all Reporting Persons timely complied with all applicable filing requirements except as follows: Alan Shapiro was late in filing three reports concerning seven transactions. Erkki Ruoslahti and Alan Walton were each late in filing one report concerning two transactions. Robert Lanza, Jonathan Atzen, and Ivan Wolkind were each late in filing one report concerning one transaction. These individuals subsequently filed their delinquent Forms.

Code of Ethics

        We have adopted a code of business conduct and ethics that applies to our directors, officers (including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions) as well as our employees. A copy of our code of business conduct and ethics is available on our website at www.advancedcell.com under "Investors—Corporate Governance." We intend to post on our website all disclosures that are required by applicable law, the rules of the Securities and Exchange Commission or OTCBB listing standards concerning any amendment to, or waiver from, our code of business conduct and ethics.

CHANGES IN CERTIFYING ACCOUNTANTS

        Pritchett, Siler & Hardy, P.C., referred to as Pritchett, served as our independent auditors for the fiscal years ended December 31, 2004 and 2003. Stonefield Josephson, Inc., referred to as Stonefield, served as independent auditors for ACT for the fiscal years ended December 31, 2004 and 2003. Upon consummation of the January 2005 merger, the financial statements of ACT became our financial statements. Accordingly, we elected to change independent accountants and to retain ACT's historical independent accountants, Stonefield Josephson, Inc.

        On May 4, 2005, we dismissed Pritchett as our independent registered public accounting firm. Pritchett had served as our independent registered public accounting firm since our inception. The reports of Pritchett on our financial statements for fiscal year ended December 31, 2004 contained no

96



adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles.

        The decision to dismiss Pritchett was based on the explanation set forth above and was approved by our full Board of Directors at such time. During fiscal year 2004 and the subsequent interim period through the date of the dismissal, we had no disagreement with Pritchett on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of Pritchett, would have caused them to make reference to such disagreement in connection with their reports for such periods. During fiscal year 2004 and the subsequent interim period through the date of the dismissal, there have been no reportable events (as defined in Regulation S-B, Item 304).We provided Pritchett with a copy of the above disclosures and requested that they furnish us with a letter addressed to the Securities and Exchange Commission stating whether they agree with the above statements and, if not, stating the respects in which they do not agree. A copy of the letter from Pritchett is attached to our Current Report on 8-K dated May 4, 2005.

        On April 17, 2007, we dismissed Stonefield Josephson, Inc. ("Stonefield") as our independent registered public accounting firm. Concurrent with this action on the same date, our audit committee appointed Singer Lewak Greenbaum & Goldstein LLP ("SLGG") as our new independent registered public accounting firm. The decision to change accountants was approved by the audit committee and ratified by the Board of Directors.

        The audit reports of Stonefield on the consolidated financial statements of Advanced Cell Technologies, Inc. and subsidiaries as of and for the years ended December 31, 2006 and 2005, did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles, except that Stonefield's report on the December 31, 2006 consolidated financial statements included an explanatory paragraph regarding the existence of substantial doubt about the company's ability to continue as a going concern.

        During the two most recent fiscal years ended December 31, 2006 and 2005 and from January 1, 2007 to the date of our dismissal of Stonefield, there have been no disagreements with Stonefield on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which if not resolved to Stonefield's satisfaction, would have caused it to make reference to the subject matter of the disagreement in connection with its reports. During the same period, there have been no reportable events, as that term is described in Item 304(a)(1)(iv) of Regulation S-B.

        A copy of a letter from Stonefield to the Securities and Exchange Commission, dated April 20, 2007, is attached as Exhibit 16.1 to this Report.

        During the two most recent fiscal years, and the subsequent interim period prior to engaging SLGG, neither the company nor anyone on its behalf consulted SLGG regarding the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the company's financial statements, and no written or oral advice was provided by SLGG that was a factor considered by the company in reaching a decision as to the accounting, auditing or financial reporting issues as set forth in Item 304(a)(2)(i) and (ii) of Regulation S-B.

ADVANCED CELL TECHNOLOGY, INC. AND SUBSIDIARY

NOTES TO FINANCIAL STATEMENTS

June 30, 2007

(UNAUDITED)

1.    ORGANIZATIONAL MATTERS

Organization

        On January 31, 2005, Advanced Cell Technology, Inc. (formerly known as A.C.T. Holdings, Inc.) (the "Company") completed the Merger with Advanced Cell, Inc. (formerly known as Advanced Cell Technology, Inc.), a Delaware corporation ("ACT"), pursuant to which a wholly-owned subsidiary of the Company merged with and into ACT, with ACT remaining as the surviving corporation and a wholly-owned subsidiary of the Company. Upon the completion of the merger, the Company ceased all of its pre-merger operations and adopted the business of ACT.

        Prior to the merger, the Company had minimal business, operations, revenues and assets, and had been involved in an industry entirely unrelated to the business of ACT. Therefore, the acquisition of ACT by the Company represented a complete change in the nature of the Company's business and operations, and changed the nature of any prior investment in the Company.

        The transaction has been accounted for as a recapitalization of ACT, the accounting acquirer. The historical financial statements presented for periods prior to the merger are those of ACT.

        On November 18, 2005, a majority of the Company's stockholders approved the reincorporation of the Company from the state of Nevada to the state of Delaware pursuant to a merger of the Company with and into a newly formed Delaware corporation, followed by a "roll up" merger to combine the operating subsidiary with the Company.

Nature of Business

        The Company is a biotechnology company focused on developing and commercializing human stem cell technology in the emerging fields of regenerative medicine and stem cell therapy. Principal activities to date have included obtaining financing, securing operating facilities and conducting research and development. The Company has no therapeutic products currently available for sale and does not expect to have any therapeutic products commercially available for sale for a period of years, if at all. These factors indicate that the Company's ability to continue its research and development activities is dependent upon the ability of management to obtain additional financing as required.

Going Concern

        As reflected in the accompanying financial statements, the Company has losses from operations, negative cash flows from operations, a substantial stockholders' deficit and current liabilities exceed current assets. The Company will thus be able to continue as a going concern and fund cash requirements for operations through September 30, 2007, with current cash reserves, including the proceeds of the bridge financing described in Note 13—Subsequent Events. Notwithstanding success in raising capital, there continues to be substantial doubt about the Company's ability to continue as a going concern.

        In view of the matters described in the preceding paragraph, recoverability of a major portion of the recorded asset amounts shown in the accompanying consolidated balance sheet is dependent upon continued operations of the Company, which, in turn, is dependent upon the Company's ability to continue to raise capital and ultimately generate positive cash flows from operations. The financial

F-7



statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classifications of liabilities that might be necessary should the Company be unable to continue its existence.

        In the first six months of 2007, management has taken or plans to take the following steps that it believes will be sufficient to provide the Company with the ability to continue in existence:

2.    SIGNIFICANT ACCOUNTING POLICIES

        Basis of Presentation—The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and to the rules and regulations of the Securities and Exchange Commission for form 10-QSB.

        Use of Estimates—These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and, accordingly, require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Specifically, our management has estimated variables used to calculate the Black Scholes and binomial lattice model calculations used to value derivative instruments discussed below under "Valuation of Derivative Instruments". In addition, management has estimated the expected economic life and value of our licensed technology, our net operating loss for tax purposes, share-based payments to compensation to employees, directors, consultants and investment banks, the useful lives of our fixed assets and our allowance for bad debts. Actual results could differ from those estimates.

        Reclassifications—Certain prior year financial statement balances have been reclassified to conform to the current year presentation. These reclassifications have no effect on the recorded net loss.

        Cash and Cash Equivalents—Cash equivalents are comprised of certain highly liquid investments with maturities of three months or less when purchased. We maintain our cash in bank deposit accounts, which at times, may exceed federally insured limits. We have not experienced any losses related to this concentration of risk.

F-8



        Accounts Receivable—We periodically assess our accounts receivable for collectibility on a specific identification basis. If collectibility of an account becomes unlikely, we record an allowance for that doubtful account. Once we have exhausted efforts to collect, we write off the account receivable against the allowance we have already created. We do not require collateral for our trade accounts receivable.

        Equipment—We record our equipment at historical cost. We expense maintenance and repairs as incurred. Depreciation is provided for on the straight-line method over three to six years. Upon disposition of equipment, the gross cost and accumulated depreciation are written off and the difference between the proceeds and the net book value is recorded as a gain or loss on sale of assets. In the case of certain assets acquired under Capital Leases, the assets are recorded net of imputed interest, based upon the net present value of future payments. Assets under capital lease are pledged as collateral for the related lease.

        Deferred Issuance Costs—Payments, either in cash or share-based payments, made in connection with the sale of debentures are recorded as deferred debt issuance costs and amortized using the effective interest method over the lives of the related debentures. The weighted average amortization period for deferred debt issuance costs is 36 months, and as redemptions occur the Company writes off the proportional amount of the original deferred issuance cost to interest expense.

        Intangible and Long-Lived Assets—We follow Statement of Financial Accounting Standards ("FAS") No. 144, "Accounting for Impairment of Disposal of Long-Lived Assets," which established a "primary asset" approach to determine the cash flow estimation period for a group of assets and liabilities that represents the unit of accounting for a long-lived asset to be held and used. Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell. During the years ended December 31, 2006 and 2005, no impairment loss was recognized.

        Fair Value of Financial Instruments—For certain of our financial instruments, including accounts receivable, account payable, accrued expenses, interest payable, bank overdraft, advances payable and notes payable, the carrying amounts approximate fair value due to their relatively short maturities.

        Valuation of Derivative Instruments—FAS 133, "Accounting for Derivative Instruments and Hedging Activities" requires bifurcation of embedded derivative instruments and measurement of fair value for accounting purposes. In addition, FAS 155, "Accounting for Certain Hybrid Financial Instruments" requires measurement of fair values of hybrid financial instruments for accounting purposes. We applied the accounting proscribed in FAS 155 to account for the 2006 Convertible Debentures described below in Note 3—Convertible Debentures 2006. In determining the appropriate fair value, the Company uses a variety of valuation techniques including Black Scholes models, Binomial Option Pricing models, Standard Put Option Binomial models and net present value of certain penalty amounts. Derivative liabilities are adjusted to reflect fair value at each period end, with any increase or decrease in the fair value being recorded in results of operations as Adjustments to Fair Value of Derivatives. The effects of interactions between embedded derivatives are calculated and accounted for

F-9



in arriving at the overall fair value of the financial instruments. In addition, the fair values of freestanding derivative instruments such as warrant derivatives are valued using Black Scholes models.

        Revenue Recognition—Our revenues are generated from license and research agreements with collaborators. Licensing revenue is recognized on a straight-line basis over the shorter of the life of the license or the estimated economic life of the patents related to the license. Deferred revenue represents the portion of the license and other payments received that has not been earned. Costs associated with the license revenue are deferred and recognized over same term as the revenue. Reimbursements of research expense pursuant to grants are recorded in the period during which collection of the reimbursement becomes assured, because the reimbursements are subject to approval.

        Research and Development Costs—Research and development costs consist of expenditures for the research and development of patents and technology, which are not capitalizable. Our research and development costs consist mainly of payroll and payroll related expenses, research supplies and research grants. Reimbursements of research expense pursuant to grants are recorded in the period during which collection of the reimbursement becomes assured, because the reimbursements are subject to approval. Research and development costs are expensed as incurred.

        Stock Based Compensation—At June 30, 2007 we had two stock-based employee compensation plans, which are described more fully in Note 9—Stock Based Compensation.

        Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS 123R, using the modified prospective transition method. Under this transition method, stock-based compensation expense is recognized in the consolidated financial statements for granted, modified or settled stock options based on estimated fair values. Results for prior periods have not been restated, as provided for under the modified prospective transition method.

        Prior to the adoption of SFAS 123R, the Company presented all tax benefits resulting from the exercise of stock options as operating cash inflows in the consolidated statements of cash flows, in accordance with the provisions of the Emerging Issues Task Force ("EITF") Issue No. 00-15, "Classification in the Statement of Cash Flows of the Income Tax Benefit Received by a Company upon Exercise of a Nonqualified Employee Stock Option." SFAS 123R requires the benefits of tax deductions in excess of the compensation cost recognized for those options to be classified as financing cash inflows rather than operating cash inflows, on a prospective basis. The impact of this change was not material to the Company.

        Net Loss Per Share—We use FAS No. 128, "Earnings Per Share" for calculating the basic and diluted loss per share. We compute basic loss per share by dividing net loss and net loss attributable to common shareholders by the weighted average number of common shares outstanding. Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional shares were dilutive. Common equivalent shares are excluded from the computation of net loss per share if their effect is anti-dilutive.

F-10



        For the three months ended June 30, 2007, approximately 58,000,000 potentially dilutive shares were excluded from the shares used to calculate diluted earnings per share as their inclusion would be anti-dilutive.

        Income Taxes—Deferred income taxes are provided using the liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of the changes in tax laws and rates of the date of enactment.

        When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination.

        Interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the statement of income.

        Concentrations and Other Risks—Currently, the Company's revenues and accounts receivable are concentrated on one customer. There is also a geographic concentration of the Company's primary activities in Northern California and Massachusetts. Other risks include the uncertainty of the regulatory environment and the effect of future regulations on the Company's business activities. As we are a biotechnology research and development company, there is also the attendant risk that someone could commence legal proceedings over our discoveries. Acts of God could also adversely affect our business.

        On February 15, 2007, the Financial Accounting Standards Board, or FASB, issued FAS No. 159, "The Fair Value Option for Financial Assets and Liabilities—Including an Amendment of FAS 115." This standard permits an entity to choose to measure many financial instruments and certain other items at fair value. This option is available to all entities. Most of the provisions in FAS 159 are elective; however, an amendment to FAS 115 "Accounting for Certain Investments in Debt and Equity Securities" applies to all entities with available for sale or trading securities. Some requirements apply

F-11


differently to entities that do not report net income. FAS 159 is effective as of the beginning of an entities first fiscal year that begins after November 15, 2007. Early adoption is permitted as of the beginning of the previous fiscal year provided that the entity makes that choice in the first 120 days of that fiscal year and also elects to apply the provisions of FAS 157 "Fair Value Measurements." We will adopt FAS 159 beginning January 1, 2008 and we are currently evaluating the potential impact the adoption of this pronouncement will have on our financial statements.

        Effective January 1, 2007, Advanced Cell Technology adopted FSP No. FIN 48-1, "Definition of Settlement in FASB Interpretation No. 48," (FSP FIN 48-1), which was issued on May 2, 2007. FSP FIN 48-1 amends FIN 48 to provide guidance on how an entity should determine whether a tax position is effectively settled for the purpose of recognizing previously unrecognized tax benefits. The term "effectively settled" replaces the term "ultimately settled" when used to describe recognition, and the terms "settlement" or "settled" replace the terms "ultimate settlement" or "ultimately settled" when used to describe measurement of a tax position under FIN 48. FSP FIN 48-1 clarifies that a tax position can be effectively settled upon the completion of an examination by a taxing authority without being legally extinguished. For tax positions considered effectively settled, an entity would recognize the full amount of tax benefit, even if the tax position is not considered more likely than not to be sustained based solely on the basis of its technical merits and the statute of limitations remains open. The adoption of FSP FIN 48-1 did not have an impact on the accompanying Financial Statements.

3.    CONVERTIBLE DEBENTURES—2006

        On September 6, 2006, we entered into a Securities Purchase Agreement with accredited investors for the issuance of an aggregate of $10,981,250 principal amount of convertible debentures with an original issue discount of $2,231,250 representing approximately 20.3%. In connection with the closing of the sale of the debentures, we received gross proceeds of $8,750,000. These convertible debentures were issued in connection with certain additional investment rights granted in connection with the convertible debentures issued in 2005, and described more fully in Note 4—Convertible Debentures—2005. The convertible debentures are convertible at the option of the holders into 38,129,340 shares of Common Stock at a fixed conversion price of $0.288 per share, subject to anti-dilution and other customary adjustments. In connection with the Securities Purchase Agreement, we also issued warrants to purchase an aggregate of 19,064,670 shares of our Common Stock. The term of the warrants is five years and the exercise price is $0.3168 per share, subject to anti-dilution and other customary adjustments. The investors have contractually agreed to restrict their ability to convert the convertible debentures, exercise the warrants and exercise the additional investment right and receive shares of our Common Stock such that the number of shares of our Common Stock held by them and their affiliates after such conversion or exercise does not exceed 4.99% of our then issued and outstanding shares of our Common Stock.

        The agreements entered into provide that the Company will pay certain cash amounts as liquidated damages in the event that the Company does not maintain an effective registration statement, or if the Company fails to timely execute stock trading activity.

F-12



        Under the terms of the agreements, principal amounts owed under the debentures became due and payable commencing six months following closing of the transaction. This term was changed to twelve months under the terms of the an amendment signed in January 2007. At that time, and each month thereafter, the Company is required to either repay 1/30 of the outstanding balance owed in cash, or convert the amount due into common stock at the lesser of $0.288 per share or 70% of the prior ten days' average closing stock price, immediately preceding the redemption. The agreements also provide that the Company may force conversion of outstanding amounts owed under the debentures into common stock, if the Company has met conditions and milestones identified above, and, additionally, has a stock price for 20 consecutive trading days that exceeds 200% of the conversion price.

        The agreement included a number of other embedded derivative instruments, and the Company has complied with the provisions of FAS 155 "Accounting for Certain Hybrid Financial Instruments", and recorded the fair value of the convertible debentures, and related embedded derivatives, as of September 6, 2006. The fair value of the debentures and related derivative instruments was valued using a combination of Binomial and Black Scholes models, resulting in a fair value of $22,200,000. The excess of this value over the face value of the Convertible Debentures was recorded through the results of operations as a debit to Charges Related to Issuance of Convertible Debentures.

        The 2006 Convertible debentures and related embedded derivatives outstanding at June 30, 2007 were again valued at fair value using a combination of Binomial and Black Scholes models, resulting in a decrease in the fair value of the liability of approximately $8,162,000 which was recorded through the results of operations as a credit to Adjustments to Fair Value of Derivatives.

        In connection with this financing, we paid cash fees to a broker-dealer of $525,000 and issued a warrant to purchase 4,575,521 shares of Common Stock at an exercise price of $0.3168 per share. The initial fair value of the warrant was estimated at approximately $3,600,000 using the Black Scholes pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%; (2) expected volatility of 176%, (3) risk-free interest rate of 4.81%, and (4) expected life of 5 years. Cash fees paid, and the initial fair value of the warrant, have been capitalized as debt issuance costs and are being amortized over 36 months, and as redemptions occur the Company writes off the proportional amount of the original deferred issuance cost to interest expense.

        The following table summarizes the 2006 Convertible Debentures and discounts outstanding at June 30, 2007 (unaudited):

2006 Convertible debentures at fair value   $ 12,472,940  
Warrant derivative discount     (1,739,346 )
Original issue discount     (913,185 )
   
 
Net convertible debentures     9,820,409  
  Less current portion     (3,273,470 )
   
 
  2006 Convertible debentures and embedded derivatives-long term   $ 6,546,939  
   
 

        As of June 30, 2007, the outstanding principal amount for the 2006 Convertible Debentures is $8,485,034.

F-13



4.    CONVERTIBLE DEBENTURES—2005

        On September 15, 2005, we entered into a Securities Purchase Agreement with accredited investors for the issuance of an aggregate of $22,276,250 principal amount of convertible debentures with an original issue discount of $4,526,250 representing approximately 20.3%. In connection with the closing of the sale of the debentures, we received gross proceeds of $17,750,000.

        The agreement included a number of embedded derivative instruments that required separate valuation in accordance with the requirements of FAS 133, EITF 05-04 and related accounting literature. The following summarizes the fair values of embedded derivatives at December 31, 2006 and June 30, 2007, followed by a description of the valuation methodology utilized to determine fair values:

Embedded Derivative Liability (Asset)

  Fair value
December 31, 2006

  Fair value
June 30, 2007

 
 
   
  (unaudited)

 
Conversion feature   $ 1,104,414   $ 298,064  
Anti-dilution protection     2,107,767     524,459  
Default provisions     46,692     7,959  
Right to provide future financing     0     0  
Company right to force conversion     (185,091 )   (45,964 )
   
 
 
    $ 3,070,782   $ 784,518  
   
 
 

        The fair value of the derivative for the conversion feature was valued as an American call option using the Binomial Option Pricing Model with the following inputs: (1) closing stock price of $0.43 at June 30, 2007 (2) exercise price equal to the $0.90 conversion price (3) volatility based upon the Company's stock trading of 198% (4) Treasury note rates with terms commensurate with the remaining term of the Notes of 4.91%, and (5) duration of the note as an amortizing debenture of approximately 0.22 years, based upon present values.

        The fair value of the derivative for anti-dilution protection was valued using a standard put option binomial model, adjusted for the probability of subsequent financing at prices below the principal's conversion option with the following inputs: (1) closing stock price as of the valuation date of $0.43 (2) exercise price equal to the $0.90 conversion price (3) volatility based upon the Company's stock trading of 198% (4) Treasury note rates with terms commensurate with the remaining term of the Notes of 4.91% and (5) duration of the note as an amortizing debenture of approximately 0.22 years based upon present values.

        The fair value of the derivative for contractual default provisions was determined by taking the monthly amortization schedule, and multiplying the result by the contractual penalty of 120%. The present value of this penalty was then adjusted by the estimated probability of default for each valuation date.

        The fair value of the derivative asset related to the Company's right to force conversion was based upon a binomial option pricing model with the following inputs: (1) closing stock price at the valuation date of $0.43 (2) exercise price of $1.80 per share which is required for the forced conversion (3) volatility based upon the Company's stock trading of 198% (4) Treasury note rate with terms

F-14



commensurate with the remaining term of the Notes of 4.91% and (5) duration of the note as an amortizing debenture of approximately 0.22 years based upon present values.

        During the three months ended June 30, 2007, a decrease in the fair value of the embedded derivative amounts of approximately $1,025,000 was recorded through results of operations as Adjustment to Fair Value of Derivatives.

        During the three months ended June 30, 2007, the Company recorded approximately $682,000 as Interest Expense for amortization of discounts for original issue discount, discount for warrant derivative, and other embedded derivatives identified above.

        In connection with this financing, we paid cash fees to a broker-dealer of $1,065,000 and issued a warrant to purchase 1,162,239 shares of Common Stock at an exercise price of $2.53 per share. The initial fair value of the warrant was estimated at approximately $1,379,000 using the Black Scholes pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%; (2) expected volatility of 64%, (3) risk-free interest rate of 3.99%, and (4) expected life of 5 years. Cash fees paid, and the initial fair value of the warrant, have been capitalized as debt issuance costs and are being amortized over 36 months under the effective interest rate method. Interest expense for the three months ended June 30, 2007 was approximately $110,000.

        In January 2007, the Company's Board of Directors agreed to reduce the exercise price of the warrants issued in connection with the 2005 debentures to $0.95 per share and to reduce the conversion price of the debentures to $0.90 per share.

        The Company has considered the impact of Emerging Issue Task Force statements, or EITFs 96-19—Debtor's Accounting for a Modification or Exchange of Debt Instruments, 02-4—Determining Whether a Debtor's Modification or Exchange of Debt Instruments is Within the Scope of FASB No. 15, and 05-7—Accounting for Modifications to conversion Options Embedded in Debt Instruments and Related Issues on the accounting treatment of the change in conversion price of the 2005 Convertible Debentures described in the paragraph above. EITF 96-19 states that a transaction resulting in a significant change in the nature of a debt instrument should be accounted for as an extinguishment of debt. The Company has concluded that the change in conversion price does not constitute a significant change in the nature of the debt and that the transaction should not be treated as an extinguishment of that debt.

        The following table summarizes the 2005 Convertible Debentures and embedded derivatives outstanding at June 30, 2007:

5.    WARRANT AND OPTION DERIVATIVES

        As described more fully in Note 4—Convertible Debentures—2005, the provisions of our convertible debenture financing completed in September 2005 permit the Company to make its monthly redemption in shares rather than cash upon satisfaction of certain conditions. Under the terms of the debenture agreement, the price per share is variable dependent upon the actual closing price of the Company's common stock. Accordingly, the total number of shares to retire outstanding principal is variable and the Company can not be assured that there are adequate authorized shares to settle all contractual obligations under the debenture agreement, and other option and warrant agreements outstanding.

        Accordingly, in accordance with the provisions of EITF 00-19, "Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Company's Own Stock" the Company has reviewed all instruments previously recorded as permanent equity under EITF 00-19 which are described in detail in Note 8—Stockholders' Equity Transactions. As of September 15, 2005, the closing date of the convertible debenture financing, a $25,600,000 increase in the fair value of instruments previously recorded as permanent equity with a value of zero was recorded based upon fair values computed under a Black Scholes model with the following assumptions: (1) dividend yield of 0% (2) expected volatility of 64% (3) risk-free interest rate of approximately 3.9% and (4) expected life and exercise prices consistent with each individual instrument.

        The accumulated fair value of these and other instruments at September 15, 2005 of approximately $27,700,000, after the increase to fair value described above, was reclassified from equity to Warrant Derivative liability in accordance with the requirements of EITF 00-19.

        At June 30, 2007 the fair value of each instrument was computed under a Black Scholes model with the following assumptions: (1) dividend yield of 0% (2) expected volatility of 155% (3) risk-free

F-16



interest rate of approximately 4.92% and (4) expected life and exercise prices consistent with each individual instrument. These calculations resulted in an aggregate value of derivative instruments of approximately $10,099,000. As a result, for the three months ended June 30, 2007 the Company recorded approximately $10,600,000 as a credit to Adjustment to Fair Value of Derivatives.

        The Company has considered the impact of Emerging Issue Task Force statements, or EITFs 96-19—Debtor's Accounting for a Modification or Exchange of Debt Instruments, 02-4—Determining Whether a Debtor's Modification or Exchange of Debt Instruments is Within the Scope of FASB No. 15, and 05-7—Accounting for Modifications to conversion Options Embedded in Debt Instruments and Related Issues on the accounting treatment of the change in conversion price of the 2005 Convertible Debentures described in the paragraph above. EITF 96-19 states that a transaction resulting in a significant change in the nature of a debt instrument should be accounted for as an extinguishment of debt. The Company has concluded that the change in conversion price does not constitute a significant change in the nature of the debt and that the transaction should not be treated as an extinguishment of that debt.

        The carrying value of the remaining 2005 debenture warrant derivatives at June 30, 2007 has been adjusted to reflect "fair value" of approximately $770,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%; (2) expected volatility of 155%, (3) risk-free interest rate of 4.89%, and (4) expected remaining life of 3.00 years. This resulted in an additional decrease in the fair value of the warrant derivative liability of approximately $775,000 which was recorded through results of operations as a credit to Adjustment to Fair Value of Derivatives.

        The carrying value of the replacement warrant derivatives at June 30, 2007 has been adjusted to reflect "fair value" of approximately $1,700,00 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%; (2) expected volatility of 155%, (3) risk-free interest rate of 4.92%, and (4) expected remaining life of 4.25. This resulted in a decrease in the fair value of the warrant derivative liability of approximately $1,538,000 which was recorded as a credit to Adjustment to Fair Value of Derivatives in the results of operations for the three months ended June 30, 2007.

        The carrying value of the January 2005 financing warrant derivatives at June 30, 2007 have been adjusted to reflect fair value of approximately $1,188,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 155%, (3) risk-free interest rate of 4.89%, and (4) expected remaining life of 1.50 years. This resulted in an additional decrease in the fair value of the warrant derivative liability of approximately $1,608,000 which was recorded through results of operations as a credit to Adjustment to Fair Value of Derivatives.

        The carrying value of the broker dealer warrant derivatives at June 30, 2007 have been adjusted to reflect fair value of approximately $1,801,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 155%, (3) risk-free interest rate of 4.89%, and (4) expected remaining life of 4.25 years. This resulted in a decrease in the fair value of the warrant derivative liability of approximately $1,578,000 which was recorded through results of operations as a credit to Adjustment to Fair Value of Derivatives.

F-17



        The carrying value of the remaining warrant derivatives at June 30, 2007 have been adjusted to reflect fair value of approximately $2,882,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 155%, (3) risk-free interest rate ranging from 4.25% to 4.89%, and (4) expected remaining life ranging from .25 years to 4.25 years. This resulted in a decrease in the fair value of the warrant derivative liability of approximately $3,557,000 which was recorded through results of operations as a credit to Adjustments to Fair Value of Derivatives.

7.    RECLASSIFICATION OF EQUITY TRANSACTIONS

        As described more fully in Note 4—Convertible Debentures 2005, the provisions of our convertible debenture financing completed in September 2005 permit the Company to make its monthly redemption in shares rather than cash upon satisfaction of certain conditions. Under the terms of the debenture agreement, the price per share is variable dependent upon the actual closing price of the Company's common stock. Accordingly, the total number of shares to retire outstanding principal is variable and the Company can not be assured that there are adequate authorized shares to settle all contractual obligations under the debenture agreement, and other option and warrant agreements outstanding.

        Accordingly, in accordance with the provisions of EITF 00-19, "Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Company's Own Stock" the Company has reviewed all instruments previously recorded as permanent equity under EITF 00-19 which are described in detail in Note 8—Stockholders' Equity Transactions. As of September 15, 2005, the closing date of the convertible debenture financing, a $25,600,000 increase in the fair value of instruments previously recorded as permanent equity with a value of zero was recorded based upon fair values computed under a Black Scholes model with the following assumptions: (1) dividend yield of 0% (2) expected volatility of 64% (3) risk-free interest rate of approximately 3.9% and (4) expected life and exercise prices consistent with each individual instrument.

F-18



        The accumulated fair value of these and other instruments at September 15, 2005 of approximately $27,700,000, after the increase to fair value described above, was reclassified from equity to Warrant Derivative liability in accordance with the requirements of EITF 00-19.

8.    STOCKHOLDERS' EQUITY TRANSACTIONS

        We are authorized to issue two classes of capital stock, to be designated, respectively, Preferred Stock and Common Stock. The total number of shares of Preferred Stock we are authorized to issue is 50,000,000 par value $0.001 per share. The total number of shares of Common Stock we are authorized to issue is 500,000,000, par value $0.001 per share. We had no Preferred Stock outstanding as of June 30, 2007. We had 59,974,205 shares of Common Stock outstanding as of June 30, 2007.

        In January 2007, the Company issued 300,000 warrants to purchase common stock at $0.96 per share in connection with consulting services provided during the quarter. The warrants were valued at approximately $225,000 using the Black Scholes pricing model with the following assumptions: (1) dividend yield of 0%; (2) expected volatility of 165%, (3) risk-free interest rate of 4.90%, and (4) expected life of 4.0 years. This warrant is classified as a warrant derivative.

        In January 2007, the Company issued 35,909 fully vested shares of Common Stock as consideration for service on the Company's Board of Directors and Audit Committee. These shares are valued at market price on date of grant.

        In January 2007, the Company issued 515,000 share of Common Stock, valued at $407,000, to employees. These shares are fully vested at issuance and are valued at fair market proce on date of grant.

        In February 2007, the Company issued 800,00 shares of Common Stock, valued at $608,000 based upon the closing price per share on the date of issuance, to Infigen, Inc. in connection with the execution of a Patent Assignment Agreement. The Company recorded the $608,000 as deferred royalty fees and will amortize over an estimated useful life of 10 years.

        In April 2007, the Company issued 85,000 shares of common stock in settlement of legal fees of approximately $68,000. The shares were valued at the closing price per share on the date of issuance.

9.    STOCK-BASED COMPENSATION

Stock Plans

        On August 12, 2004, ACT's Board of Directors approved the establishment of the 2004 Stock Option Plan (the "2004 Stock Plan"). Stockholder approval was received on December 13, 2004. The total number of common shares available for grant and issuance under the plan may not exceed 2,800,000 shares, subject to adjustment in the event of certain recapitalizations, reorganizations and similar transactions. Common stock purchase options may be exercisable by the payment of cash or by other means as authorized by the Board of Directors or a committee established by the Board of Directors. At September 30, 2006, ACT had granted 2,604,000 common share purchase options under the plan.

F-19



        On December 13, 2004, ACT's Board of Directors and stockholders approved the establishment of the 2004 Stock Option Plan II (the "2004 Stock Plan II"). The total number of common shares available for grant and issuance under the plan may not exceed 1,301,161 shares, subject to adjustment in the event of certain recapitalizations, reorganizations and similar transactions. Common stock purchase options may be exercisable by the payment of cash or by other means as authorized by the Board of Directors or a committee established by the Board of Directors.

        On January 31, 2005, the Company's Board of Directors approved the establishment of the 2005 Stock Incentive Plan (the "2005 Plan"), subject to approval of our shareholders. The total number of common shares available for grant and issuance under the plan may not exceed 9 million shares, plus an annual increase on the first day of each of the Company's fiscal years beginning in 2006 equal to 5% of the number of shares of our common stock outstanding on the last day of the immediately preceding fiscal year, subject to adjustment in the event of certain recapitalizations, reorganizations and similar transactions. Common stock purchase options may be exercisable by the payment of cash or by other means as authorized by the Board of Directors or a committee established by the Board of Directors.

        Pursuant to the 2005 Plan, on February 5, 2007, we granted 1,300,000 common stock purchase options to employees. The options granted have an exercise price of $0.76 per share, the market price of the Company's stock on the date of grant. The options vest monthly over a period of 4 years. The fair value of the options was estimated at $953,000 using the Black Scholes option pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%; (2) expected volatility of 163%, (3) risk-free interest rate of 4.80%, and (4) expected life of 6.25 years. The fair value was treated in accordance with FAS 123(R) and is being amortized over a period of four years. Since the Company vests options on the graded method, the fair value is amortized on a straight line basis which approximates the vesting schedule.

        The assumptions used in the Black Scholes models referred to above are based upon the following data: (1) Expected dividends on the underlying shares over the remaining term of the option are based upon historical dividend data (2) The expected volatility of the price of the underlying shares over the expected term of the option is based upon historical share price data (3) The expected term of the option is estimated by considering the contractual term of the option, the vesting period of the option, the employees' expected exercise behavior and the post-vesting employee turnover rate.

        Aggregate option activity for the 2004 and 2005 stock option plans is as follows:

        As of June 30, 2007 and December 31, 2006, there were 8,720,879 and 7,503,665 exercisable options outstanding at a weighted average exercise price per share of $0.72 and $0.61, respectively, and with a weighted average life of 8.25 years and 8.40 years respectively.

        During the period, no options were forfeited or exercised. The aggregate intrinsic value of all options vested is approximately $1,847,000. All fully vested options in the Company are exercisable.

        The fair value of all options vested during the year ended December 2006 and the six months ended June 30, 2007 was $522,516 and $344,984 respectively.

        For the three and six months ended March 31, 2007 and June 30, 2007, a charge of approximately $35,000 and $35,000, and $180,000 and $94,000 respectively was recorded through results of operations as General and Administrative and Research and Development expense related to share based compensation. These amounts were calculated using a pre-vesting forfeiture rate of 13%, based on historical employee turnover and forfeiture data.

        A summary of the status of unvested employee stock options as of June 30, 2007 and changes during the period then ended, is presented below:

        As of June 30, 2007, the total remaining unrecognized compensation cost related to unvested stock options amounted to $1.4 million, which will be amortized over the weighted-average remaining requisite service period of 4.0 years.

10.    COMMITMENTS AND CONTINGENCIES

        We are a party to a license agreement with the University of Massachusetts, as amended from time to time (the "UMass License"). Under the UMass License, we were granted certain exclusive rights to license and sublicense certain products and services invented as part of the collaborative effort. The term of the UMass License extends to the later of the expiration of the related patents currently 2021, or April 16, 2006. We are required to pay royalties ranging from 2.5% to 4.5% of net sales of licensed products and services, as defined. Minimum royalties of $45,000 per year must be paid to UMass. For 2006 and 2007, we have paid only the minimum royalty required. Additionally, we are required to pay sublicense fees of 18% for sublicense income, as defined. We are required to spend a minimum annual amount of $200,000 on research and development. The Company did, in fact, fulfill this requirement.

F-21



        In May 2006 we entered into exclusive and non-exclusive sublicense agreements with a company whereby we are the licensee of certain of their technology and intellectual property for a cash payment of $300,000. The agreement requires we pay minimum annual royalties of $25,000 per annum for 2006, $37,500 for 2007 and $50,000 each year thereafter through the term of the agreement. The initial license fees paid have been capitalized and will be amortized over the life of the underlying intellectual property, estimated to be approximately ten years.

        In March 2006 we entered into an exclusive sublicense agreement with TranXenoGen, Inc. whereby we are the exclusive licensee of certain of TranXenoGen's technology and intellectual property. Pursuant to this agreement we issued 163,399 shares of common stock with a fair value of approximately $239,000 and made a cash payment during the first quarter of 2006 of $140,000. We had previously paid $20,000 as an option payment related to the TranXenoGen technology. The total value paid for this license agreement of $399,000 has been capitalized and will be amortized over the life of the underlying intellectual property, estimated to be approximately seven years.

        During 2004, we entered into license agreements with two parties, the terms of which provide for the initial payment of the license fee through an aggregate of six promissory notes totaling $1,400,000. The notes mature as follows: $333,333 on December 1, 2005; $666,667 on December 1, 2006; and $400,000 on June 1, 2007. There is no stated interest rate for $1,000,000 of notes, the remaining $400,000 bear interest at 10% per year, but only if the notes are not paid at maturity. Because of the uncertainty of the ultimate collection of the principal amount of the notes, they have not been recorded in the financial statements and will not be recorded until their collectibility is reasonable assured.

        The Company entered into a lease for office and laboratory space in Massachusetts commencing December 2004 and expiring April 2010 and for office space in California commencing November 2005 and expiring May 2008. Annual minimum lease payments are as follows:

Year 1   $ 550,967
Year 2     242,670
Year 3     206,472

        During 2005, the Company entered into a lease for laboratory equipment commencing November 29, 2005 and expiring May 31, 2008. Annual minimum lease payments are as follows:

2007     53,459  
2008     36,655  
   
 
      90,114  
Imputed interest     (12,520 )

        Rent expense recorded in the financial statements for the three month and six month period ended June 30, 2007 and 2006 was approximately $324,000, $652,249, $326,000 and $416,348, respectively.

        We have entered into employment contracts with certain executives and research personnel. The contracts provide for salaries, bonuses and stock option grants, along with other employee benefits. The employment contracts generally have no set term and can be terminated by either party. There is a provision for payments of three months to one year of annual salary as severance if we terminate a contract without cause, along with the acceleration of certain unvested stock option grants.

11.    INCOME TAXES

        The Company files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local income tax examinations by tax authorities for years before 2001.

        The Company adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes ("FIN 48"), on January 1, 2007. As a result of the implementation of FIN 48, the Company reduced its net operating loss carryforward by $1,550,000. This reduction of the net operating loss carryforward translated into a reduction of the gross deferred tax asset of $658,500, with a corresponding reduction of the valuation allowance against that deferred tax asset. Due to the offsetting effect of the reduction of the valuation allowance, the adoption of Interpretation No. 48 had no impact on the Company's balance sheets or statements of operations.

        Included in the deferred tax balance at June 30, 2007 are $4.4 million of tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Because of the impact of the valuation allowance, the disallowance of the shorter deductibility period would not affect the annual effective tax rate.

        As the Company has significant net operating loss carryforwards, even if certain of the Company's tax positions were disallowed, it is not foreseen that the Company would have to pay any taxes in the near future. Consequently, the Company does not calculate the impact of interest or penalties on amounts that might be disallowed.

12.    GAIN ON SETTLEMENT WITH ROTHWELL FIGG

        In April, 2007, the Company settled outstanding payable amounts to Rothwell Figg. In total, $311,381 worth of liabilites were settled. As part of the settlement, the Company issued 85,000 shares worth a total of $68,000, and made three monthly payments totaling $50,000. As a result, the Company recognized a gain on this transaction totaling $193,861.

13.    SUBSEQUENT EVENTS

        In July 2007, the Company made its monthly redemptions of convertible debentures described in Note 4. The terms of the agreement provide for payment in cash or stock at the company's discretion. In connection with the July redemption, the Company issued approximately 983,149 shares of common stock and redeemed approximately $501,406 in Notes Payable.

F-23



        In August 2007, the Company made its monthly redemptions of convertible debentures described in Note 4. In connection with the August redemptions, the Company issued approximately 1,176,370 shares of common stock and redeemed approximately $399,966 in Notes Payable.

        At June 30, 2007, approximately 220,297 of the shares related to the July redemption had been preliminarily issued by the transfer agent in accordance with the terms of the debenture agreement. Such shares are not reflected as issued and outstanding by the company prior to finalizing share and cash payments in connection with the redemption in July 2007.

        On July 31, 2007, the Company entered into a definitive merger agreement pursuant to which a wholly owned subsidiary of the Company will merge with and into Mytogen, with Mytogen as the surviving entity. With the definitive merger agreement approved and executed by both parties, the Company and Mytogen anticipate closing the transaction within ten days following the satisfaction of certain closing conditions, which to date have not yet been satisfied. The merger agreement provides for an aggregated purchase consideration of 8,064,516 restricted shares of the Company's common stock, plus the assumption of certain Mytogen liabilities. Mytogen shareholders will also receive a warrant to purchase an additional 1.5 million shares of the Company's common stock at $0.75 subject to the achievement of certain milestones.

        On August 14, 2007, certain existing investors of the Company advanced $300,000 to the Company pursuant to a bridge loan commitment. The bridge loan commitment entered into on August 14, 2007 provides a total of up to $600,000 of interim bridge financing to the Company structured in the form of a convertible note with draws to be made in the Company's discretion. Such bridge financing shall be used to fund the working capital needs of the Company while the Company continues to seek long-term financing over the course of the next several weeks.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Advanced Cell Technology, Inc. Alameda, California

        We have audited the accompanying consolidated balance sheet of Advanced Cell Technology, Inc. as of December 31, 2006 and the related consolidated statements of operations, stockholders' deficit, and cash flows for each of the years in the two-year period ended December 31, 2006. These financial statements are the responsibility of the company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Advanced Cell Technology, Inc. as of December 31, 2006 and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2006 in conformity with accounting principles generally accepted in the United States of America.

        As discussed in Note 11 to the consolidated financial statements, in 2006 the Company adopted Statement of Financial Accounting Standards No. 123 (Revised 2004), Share-Based Payment.

        The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has minimal sources of revenue, incurred substantial net losses, has substantial monetary liabilities in excess of monetary assets and accumulated deficits as of December 31, 2006. These matters, among others, raise a substantial doubt about the Company's ability to continue as a going concern. Management's plans concerning these matters are described in Note 1. These consolidated financial statements do not included any adjustments relating to the recoverability and classification of recorded assets, or amounts and classification of liabilities that might be necessary in the event the Company cannot continue in existence.

ADVANCED CELL TECHNOLOGY, INC. AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2006

1.    ORGANIZATIONAL MATTERS

Organization

        On January 31, 2005, Advanced Cell Technology, Inc. (formerly known as A.C.T. Holdings, Inc.) (the "Company") completed a merger with Advanced Cell, Inc. (formerly known as Advanced Cell Technology, Inc.), a Delaware corporation ("ACT"), pursuant to which a wholly-owned subsidiary of the Company merged with and into ACT, with ACT remaining as the surviving corporation and a wholly-owned subsidiary of the Company. Upon the completion of the merger, the Company ceased all of its pre-merger operations and adopted the business of ACT.

        Prior to the merger, the Company had minimal business, operations, revenues and assets, and had been involved in an industry entirely unrelated to the business of ACT. Therefore, the acquisition of ACT by the Company represented a complete change in the nature of the Company's business and operations, and changed the nature of any prior investment in the Company.

        The transaction has been accounted for as a recapitalization of ACT, the accounting acquirer. The historical financial statements presented for periods prior to the merger are those of ACT.

        On November 18, 2005, a majority of the Company's stockholders approved the reincorporation of the Company from the state of Nevada to the state of Delaware pursuant to a merger of the Company with and into a newly formed Delaware corporation, followed by a "roll up" merger to combine the operating subsidiary with the Company.

Nature of Business

        The Company is a biotechnology company focused on developing and commercializing human stem cell technology in the emerging fields of regenerative medicine and stem cell therapy. Principal activities to date have included obtaining financing, securing operating facilities and conducting research and development. The Company has no therapeutic products currently available for sale and does not expect to have any therapeutic products commercially available for sale for a period of years, if at all. These factors indicate that the Company's ability to continue its research and development activities is dependent upon the ability of management to obtain additional financing as required.

Going Concern

        As reflected in the accompanying consolidated financial statements, the Company has losses from operations, negative cash flows from operations, a substantial stockholders' deficit and current liabilities exceed current assets. These matters raise substantial doubt about the Company's ability to continue as a going concern and fund cash requirements for operations through March 15, 2008. As more fully described in Note 5—Convertible Debentures—2006 and Note 7—Warrant Derivatives, the Company was able to raise cash in the quarter ended September 30, 2006. Notwithstanding success in raising capital, there continues to be substantial doubt about the Company's ability to continue as a going concern.

        In view of the matters described in the preceding paragraph, recoverability of a major portion of the recorded asset amounts shown in the accompanying consolidated balance sheet is dependent upon continued operations of the Company, which, in turn, is dependent upon the Company's ability to continue to raise capital and ultimately generate positive cash flows from operations. The financial

F-32



statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classifications of liabilities that might be necessary should the Company be unable to continue its existence.

        During 2006, management has taken or has made plans to take the following steps that it believes will be sufficient to provide the Company with the ability to continue in existence:

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        Basis of Presentation—The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and to the rules and regulations of the Securities and Exchange Commission for form 10-KSB.

        Principles of Consolidation—The accounts of Holdings and ACT are included in the accompanying consolidated financial statements for the period from January 1, 2005 to November 18, 2005, when the shareholders approved the roll-up merger to combine the two companies. During the period from January 1, 2005 to November 18, 2005, all intercompany balances and transactions were eliminated in consolidation.

        Use of Estimates—These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and, accordingly, require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Specifically, our management has estimated variables used to calculate the Black Scholes and binomial lattice model calculations used to value derivative instruments discussed below under "Valuation of Derivative Instruments". In addition, management has estimated the expected economic life and value of our licensed technology, our net operating loss for tax purposes, share-based payments to compensation to employees, directors, consultants and investment banks, the useful lives of our fixed assets and our allowance for bad debts. Actual results could differ from those estimates.

F-33



        Reclassifications—Certain prior year financial statement balances have been reclassified to conform to the current year presentation. These reclassifications have no effect on the recorded net loss.

        Cash and Cash Equivalents—Cash equivalents are comprised of certain highly liquid investments with maturities of three months or less when purchased. We maintain our cash in bank deposit accounts, which at times, may exceed federally insured limits. We have not experienced any losses related to this concentration of risk.

        Accounts Receivable—We periodically assess our accounts receivable for collectibility on a specific identification basis. If collectibility of an account becomes unlikely, we record an allowance for that doubtful account. Once we have exhausted efforts to collect, we write off the account receivable against the allowance we have already created. We do not require collateral for our trade accounts receivable.

        Equipment—We record our equipment at historical cost. We expense maintenance and repairs as incurred. Depreciation is provided for on the straight-line method over three to six years. Upon disposition of equipment, the gross cost and accumulated depreciation are written off and the difference between the proceeds and the net book value is recorded as a gain or loss on sale of assets. In the case of certain assets acquired under Capital Leases, the assets are recorded net of imputed interest, based upon the net present value of future payments. Assets under capital lease are pledged as collateral for the related lease.

        Deferred Issuance Costs—Payments, either in cash or share-based payments, made in connection with the sale of debentures are recorded as deferred debt issuance costs and amortized using the effective interest method over the lives of the related debentures. The weighted average amortization period for deferred debt issuance costs is 36 months.

        Intangible and Long-Lived Assets—We follow Statement of Financial Accounting Standards ("FAS") No. 144, "Accounting for Impairment of Disposal of Long-Lived Assets," which established a "primary asset" approach to determine the cash flow estimation period for a group of assets and liabilities that represents the unit of accounting for a long-lived asset to be held and used. Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell. During the years ended December 31, 2006 and 2005, no impairment loss was recognized.

        Fair Value of Financial Instruments—For certain of our financial instruments, including accounts receivable, account payable, accrued expenses, interest payable, bank overdraft, advances payable and notes payable, the carrying amounts approximate fair value due to their relatively short maturities.

        Valuation of Derivative Instruments—FAS 133, "Accounting for Derivative Instruments and Hedging Activities" requires bifurcation of embedded derivative instruments and measurement of fair value for accounting purposes. In addition, FAS 155, "Accounting for Certain Hybrid Financial Instruments" requires measurement of fair values of hybrid financial instruments for accounting purposes. We applied the accounting proscribed in FAS 155 to account for the 2006 Convertible Debentures

F-34



described below in Note 5—Convertible Debentures 2006. In determining the appropriate fair value, the Company uses a variety of valuation techniques including Black Scholes models, Binomial Option Pricing models, Standard Put Option Binomial models and net present value of certain penalty amounts. Derivative liabilities are adjusted to reflect fair value at each period end, with any increase or decrease in the fair value being recorded in results of operations as Adjustments to Fair Value of Derivatives. The effects of interactions between embedded derivatives are calculated and accounted for in arriving at the overall fair value of the financial instruments. In addition, the fair values of freestanding derivative instruments such as warrant derivatives are valued using Black Scholes models.

        Revenue Recognition—Our revenues are generated from license and research agreements with collaborators. Licensing revenue is recognized on a straight-line basis over the shorter of the life of the license or the estimated economic life of the patents related to the license. Deferred revenue represents the portion of the license and other payments received that has not been earned. Costs associated with the license revenue are deferred and recognized over same term as the revenue. Reimbursements of research expense pursuant to grants are recorded in the period during which collection of the reimbursement becomes assured, because the reimbursements are subject to approval.

        Research and Development Costs—Research and development costs consist of expenditures for the research and development of patents and technology, which are not capitalizable. Our research and development costs consist mainly of payroll and payroll related expenses, research supplies and research grants. Reimbursements of research expense pursuant to grants are recorded in the period during which collection of the reimbursement becomes assured, because the reimbursements are subject to approval. Research and development costs are expensed as incurred.

        Stock Based Compensation—At December 31, 2006, we had two stock-based employee compensation plans, which are described more fully in Note 11—Stock Based Compensation.

        Prior to the January 1, 2006 adoption of the FAS No. 123(R), "Share-Based Payment," the Company accounted for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations. Because the stock option grant price equaled the market price on the date of grant, no compensation expense was recognized by the Company for stock-based compensation. As permitted by SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123") stock-based compensation was included as a pro forma disclosure in the notes to the consolidated financial statements.

        Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS 123R, using the modified prospective transition method. Under this transition method, stock-based compensation expense is recognized in the consolidated financial statements for granted, modified or settled stock options based on estimated fair values. Results for prior periods have not been restated, as provided for under the modified prospective transition method.

        Prior to the adoption of SFAS 123R, the Company presented all tax benefits resulting from the exercise of stock options as operating cash inflows in the consolidated statements of cash flows, in accordance with the provisions of the Emerging Issues Task Force ("EITF") Issue No. 00-15, "Classification in the Statement of Cash Flows of the Income Tax Benefit Received by a Company

F-35



upon Exercise of a Nonqualified Employee Stock Option." SFAS 123R requires the benefits of tax deductions in excess of the compensation cost recognized for those options to be classified as financing cash inflows rather than operating cash inflows, on a prospective basis. The impact of this change was not material to the Company.

        Net Loss Per Share—We use FAS No. 128, "Earnings Per Share" for calculating the basic and diluted loss per share. We compute basic loss per share by dividing net loss and net loss attributable to common shareholders by the weighted average number of common shares outstanding. Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional shares were dilutive. Common equivalent shares are excluded from the computation of net loss per share if their effect is anti-dilutive.

        For the twelve months ended December 31, 2006, 76,941,797 potentially dilutive shares were excluded from the shares used to calculate diluted earnings per share as their inclusion would reduce net loss per share. There were 40,104,105 potentially dilutive shares at December 31, 2005.

        Concentrations and Other Risks—Currently, the Company's revenues and accounts receivable are concentrated on one customer. There is also a geographic concentration of the Company's primary activities in Northern California and Massachusetts. Other risks include the uncertainty of the regulatory environment and the effect of future regulations on the Company's business activities. As we are a biotechnology research and development company, there is also the attendant risk that someone could commence legal proceedings over our discoveries. Acts of God could also adversely affect our business.

Recent Accounting Pronouncements

        On February 15, 2007, the Financial Accounting Standards Board, or FASB, issued FAS No. 159, "The Fair Value Option for Financial Assets and Liabilities—Including an Amendment of FAS 115." This standard permits an entity to choose to measure many financial instruments and certain other items at fair value. This option is available to all entities. Most of the provisions in FAS 159 are elective; however, an amendment to FAS 115 "Accounting for Certain Investments in Debt and Equity Securities" applies to all entities with available for sale or trading securities. Some requirements apply differently to entities that do not report net income. FAS 159 is effective as of the beginning of an entities first fiscal year that begins after November 15, 2007. Early adoption is permitted as of the beginning of the previous fiscal year provided that the entity makes that choice in the first 120 days of that fiscal year and also elects to apply the provisions of FAS 157 "Fair Value Measurements." We will adopt FAS 159 beginning January 1, 2008 and we are currently evaluating the potential impact the adoption of this pronouncement will have on our financial statements.

        In December 2006, the FASB posted FASB Staff Position, or FSP, 00-19-2, "Accounting for Registration Payment Arrangements." This FSP specifies that the contingent obligation to make future payments or otherwise transfer consideration under a registration payment arrangement, whether issued as a separate agreement or included as a provision of a financial instrument or other agreement should be separately recognized and measured in accordance with FAS No. 5, "Accounting for Contingencies." This FSP further clarifies that a financial instrument subject to a registration payment arrangement

F-36



should be accounted for in accordance with other applicable GAAP without regard to the contingent obligation to transfer consideration pursuant to the registration payment arrangement. This FSP is effective immediately for registration payment arrangements and financial instruments subject to those arrangements that were entered into or modified subsequent to December 15, 2006. For registration payment arrangements and financial instruments subject to those arrangements that were entered into prior to December 15, 2006, the FSP is effective for fiscal years beginning after December 15, 2006, and interim periods within those fiscal years. We will adopt FSP 00-19-2 beginning January 1, 2007 and we are currently evaluating the potential impact the adoption of this pronouncement will have on our financial statements.

        In September 2006, the FASB issued FAS No. 158, "Employers' Accounting for Defined Benefit Pension and Other Postretirement Plans." This Statement requires companies to recognize in their statement of financial position an asset for a plan's overfunded status or a liability for a plan's underfunded status and to measure a plan's assets and its obligations that determine its funded status as of the end of the company's fiscal year. Additionally, FAS 158 requires companies to recognize changes in the funded status of a defined benefit postretirement plan in the year that the changes occur and those changes will be reported in comprehensive income. We have adopted FAS 158, and there was no impact on our financial statements.

        In September 2006, the Financial Accounting Standards Board, or FASB, issued FAS No. 157, Fair Value Measurements, or FAS 157, which provides guidance on how to measure assets and liabilities that use fair value. This Statement clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. FAS 157 will apply whenever another generally accepted accounting principle requires, or permits, assets or liabilities to be measure at fair value but does not expand the use of fair value to any new circumstances. This statement will also require additional disclosures in both annual and quarterly reports. FAS 157 is effective for fiscal years beginning after November 2007, and will be adopted by us beginning January 1, 2008. We are currently evaluating the potential impact this statement may have on our financial statements, but do not believe the impact of adoption will be material.

        In September 2006, the SEC staff issued Staff Accounting Bulletin, or SAB, No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, or SAB 108. SAB 108 provides guidance on the consideration of the effects of prior year misstatements in quantifying current year misstatements for the purpose of determining whether the current year's financial statements are materially misstated. SAB 108 is effective for fiscal years ending after November 15, 2006. We will initially apply the provisions of SAB 108 in connection with the preparation of our annual financial statements for the year ending December 31, 2006. We have evaluated the potential impact that SAB 108 may have on our financial statements and do not believe the impact of the application of this guidance will be material.

        In July 2006, the FASB issued Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109, Accounting for Income Taxes ("FIN No. 48"). This interpretation creates a single model to address uncertainty in tax positions. FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. The

F-37



interpretation also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for years beginning after December 15, 2006. Management of the Company is evaluating the impact of this pronouncement, but does not anticipate that it will have a significant impact on its financial statements.

        In February 2006, the FASB issued FAS No. 155, Accounting for Certain Hybrid Instruments. This standard amends the guidance in FASB Statements No. 133, Accounting for Derivative Instruments and Hedging Activities, and No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities. Statement 155 allows financial instruments that have embedded derivatives to be accounted for as a whole (eliminating the need to bifurcate the derivative from its host) if the holder elects to account for the whole instrument on a fair value basis. The Company has adopted FAS 155 and applies it to all relevant financing transactions from the date of adoption.

        In September 2005, the EITF reached a consensus on Issue 05-8, "Income Tax Consequences of Issuing Convertible Debt with a Beneficial Conversion Feature." EITF Issues No. 98-5, "Accounting for Convertible Securities with Beneficial Conversion Features or Contingently Adjustable Conversion Ratios," and No. 00-27, "Application of Issue No. 98-5 to Certain Convertible Instruments," provide guidance on how companies should bifurcate convertible debt issued with a beneficial conversion feature into a liability and an equity component. For income tax purposes, such an instrument is only recorded as a liability. A question has been raised as to whether a basis difference results from the issuance of convertible debt with a beneficial conversion feature and, if so, whether the basis difference is a temporary difference. We do not expect the provisions of this consensus to have a material impact on our financial position, results of operations or cash flows.

        In September 2005, the EITF discussed Issue 05-4, The Effect of a Liquidated Damages Clause on a Freestanding Instrument Subject to EITF Issue No. 00-19, "Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock." The Effect of a Liquidated Damages Clause on a Freestanding Financial Instrument Subject to EITF Issue No. 00-19, "Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company's Own Stock." Issuance of a registration rights agreement with a liquidated damages clause is common when equity instruments, stock purchase warrants, and financial instruments that are convertible into equity securities are issued. The agreement requires the issuer to use its "best efforts" to file a registration statement for the resale of the equity instruments or the shares of stock underlying the stock purchase warrant or convertible financial instrument and have it declared effective by the end of a specified grace period. The issuer may also be required to maintain the effectiveness of the registration statement for a period of time or pay a liquidated damage penalty to the investor each month until the registration statement is declared effective. Given the potential significance of the penalty, a question arises as to the effect, if any, this feature has on the related financial instruments if they are subject to the scope of Issue 00-19. The company took the provisions of this issue into account in their accounting for the period.

        In September 2005, the EITF reached a consensus on Issue 05-7, "Accounting for Modifications to Conversion Options Embedded in Debt Securities and Related Issues." EITF Issue No. 96-19, "Debtor's Accounting for a Modification or Exchange of Debt Instruments," provides guidance on whether modifications of debt result in an extinguishment of that debt. In certain situations, companies may change the terms of a conversion option as part of a debt modification, which may result in the

F-38



following circumstances: (a) the change in the conversion option's terms causes the fair value of the conversion option to change but does not result in the modification meeting the condition in Issue 96-19 that would require the modification to be accounted for as an extinguishment of debt, and (b) the change in the conversion option's terms did not result in separate accounting for the conversion option under Statement 133. When both of these circumstances exist, questions have arisen regarding whether (a) the modification to the conversion option, which changes its fair value, should affect subsequent interest expense recognition related to the debt and (b) a beneficial conversion feature related to a debt modification should be recognized by the borrower if the modification increases the intrinsic value of the debt. We do not expect the provisions of this consensus to have a material impact on our financial position, results of operations or cash flows.

        In June 2005, the EITF reached a consensus on Issue 05-2, "The Meaning of "Conventional Convertible Debt Instrument" in EITF Issue 00-19. Paragraph 4 of Issue 00-19 states that "the requirements of paragraphs 12-32 of this issue do not apply if the hybrid contract is a conventional convertible debt instrument in which the holder may only realize the value of the conversion option by exercising the option and receiving the entire proceeds in a fixed number of shares or the equivalent amount of cash (at the discretion of the issuer)". The term "conventional convertible debt instrument" is not defined in Issue 00-19 and, as a result, questions have arisen regarding when a convertible debt instrument should be considered "conventional" for purposes of Issue 00-19. A question has also arisen related to whether conventional convertible preferred stock should be treated similar to conventional convertible debt. We do not expect the provisions of this consensus to have a material impact on our financial position, results of operations or cash flows.

        In June 2005, the EITF reached a consensus on Issue 05-6, Determining the Amortization Period for Leasehold Improvements, which requires that leasehold improvements acquired in a business combination or purchased subsequent to the inception of a lease be amortized over the lesser of the useful life of the assets or a term that includes renewals that are reasonably assured at the date of the business combination or purchase. EITF 05-6 is effective for periods beginning after July 1, 2005. We do not expect the provisions of this consensus to have a material impact on our financial position, results of operations or cash flows.

        In March 2005, the FASB issued FASB Interpretation No. 47, "Accounting for Conditional Asset Retirement Obligations" ("FIN 47"). FIN 47 provides guidance relating to the identification of and financial reporting for legal obligations to perform an asset retirement activity. The Interpretation requires recognition of a liability for the fair value of a conditional asset retirement obligation when incurred if the liability's fair value can be reasonably estimated. FIN 47 also defines when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. The provision is effective no later than the end of fiscal years ending after December 15, 2005. The Company adopted FIN 47 beginning the first quarter of fiscal year 2006 and does not believe the adoption will have a material impact on its consolidated financial position or results of operations or cash flows.

        In May 2005, the FASB issued FAS No. 154, "Accounting Changes and Error Corrections—a replacement of APB Opinion No. 20 and FAB Statement No. 3". FAS No. 154 requires retrospective application to prior periods' financial statements of changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. FAS

F-39



No. 154 also requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle, such as a change in nondiscretionary profit-sharing payments resulting from an accounting change, should be recognized in the period of the accounting change. FAS No. 154 also requires that a change in depreciation, amortization or depletion method for long-lived, non-financial assets be accounted for as a change in accounting estimate effected by a change in accounting principle. FAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. Early adoption is permitted for accounting changes and corrections of errors made in fiscal years beginning after the date this Statement is issued. Management does not expect the implementation of this new standard to have a material impact on our financial position, results of operations and cash flows.

        In March 2005, the SEC released Staff Accounting Bulletin No. 107, "Share-Based Payment" ("SAB 107"), which provides interpretive guidance related to the interaction between FAS 123(R) and certain SEC rules and regulations. It also provides the SEC staff's views regarding valuation of share-based payment arrangements. In April 2005, the SEC amended the compliance dates for FAS 123(R), to allow companies to implement the standard at the beginning of their next fiscal year, instead of the next reporting period beginning after June 15, 2005. Management is currently evaluating the impact SAB 107 will have on our consolidated financial statements.

3.    DEFERRED ROYALTY FEES

        Deferred royalty fees represent cash fees and stock based compensation paid by the Company for certain licenses that have been capitalized. Such licenses are utilized in connection with the Company's operations, and are also sublicensed to third parties.

        The following table summarizes the annual amounts of these fees that are amortized to cost of revenue to appropriately match both sublicense fee income and the period in which the technology is utilized.

Amortization in 2007   $ 270,474  
Amortization in 2008     270,474  
Amortization in 2009     270,474  
Amortization in 2010     270,474  
Amortization in 2011 and beyond     206,199  
   
 
Total Deferred Royalty Fees     1,288,095  
Less current portion     (225,475 )
   
 
Long Term Deferred Royalty Fees   $ 1,062,620

4.    PROPERTY AND EQUIPMENT

        Our property and equipment as of December 31, 2006 is as follows:

Machinery and equipment   $ 1,625,624  
Computers and office equipment     367,680  
Leasehold improvements     124,902  
Furniture and fixtures     76,201  
  Total property and equipment     2,194,407  
Accumulated depreciation     (1,112,727 )
   
 
  Property and equipment, net   $ 1,081,680  
   
 

        Depreciation expense amounted to $290,536 and $107,388 during the twelve months ended December 31, 2006 and 2005, respectively. Accumulated depreciation at December 31, 2006 includes approximately $98,000 related to capital leases with a net book value of approximately $239,000.

5.    CONVERTIBLE DEBENTURES—2006

        On September 6, 2006, we entered into a Securities Purchase Agreement with accredited investors for the issuance of an aggregate of $10,981,250 principal amount of convertible debentures with an original issue discount of $2,231,250 representing approximately 20.3% of the principal amount. In connection with the closing of the sale of the debentures, we received gross proceeds of $8,750,000. These convertible debentures were issued in connection with certain additional investment rights granted in connection with the convertible debentures issued in 2005, and described more fully in Note 6—Convertible Debentures—2005. The convertible debentures are convertible at the option of the holders into 38,129,340 shares of Common Stock at a fixed conversion price of $0.288 per share, subject to anti-dilution and other customary adjustments. In connection with the Securities Purchase Agreement, we also issued warrants to purchase an aggregate of 19,064,670 shares of our Common Stock. The term of the warrants is five years and the exercise price is $0.3168 per share, subject to anti-dilution and other customary adjustments. The investors have contractually agreed to restrict their ability to convert the convertible debentures, exercise the warrants and receive shares of our Common Stock such that the number of shares of our Common Stock held by them and their affiliates after such conversion or exercise does not exceed 4.99% of our then issued and outstanding shares of our Common Stock.

        The agreements entered into provide that we will pay certain cash amounts as liquidated damages in the event that the Company does not maintain an effective registration statement covering the shares issuable under the debentures and the warrants, or if the Company fails to timely execute stock issuances.

        Under the terms of the agreements, principal amounts owed under the debentures become due and payable commencing six months following closing of the transaction. At that time, and each month thereafter, the Company is required to either repay 1/30 of the outstanding balance owed in cash, or convert the amount due into common stock at the lesser of $0.288 per share or 85% of the prior ten days' average closing stock price, immediately preceding the redemption. The agreements also provide that the Company may force conversion of outstanding amounts owed under the debentures into

F-41



common stock, if the Company has met certain conditions and milestones, and, additionally, has a stock price for 20 consecutive trading days that exceeds 200% of the conversion price.

        These agreements, as well as the 2005 Convertible Debentures (See Note 6) include certain restrictive covenants including a restriction on incurring additional indebtedness, or liens, a restriction on repurchasing shares and a restriction on paying dividends.

        The agreements included a number of other embedded derivative instruments, and the Company has applied the provisions of FAS 155 "Accounting for Certain Hybrid Financial Instruments", to record the fair values of the convertible debentures, and related derivatives, as of September 6, 2006, the date of issuance. The fair values of the debentures and related derivative instruments were valued using a combination of Binomial and Black-Scholes models, resulting in an initial fair value of approximately $22,200,000. The effects of interactions between embedded derivatives are calculated and accounted for in arriving at the overall fair value of the financial instruments. The excess of the fair value over the transaction price of the Convertible Debentures was recorded through the results of operations as a debit of approximately $11,200,000 to Charges Related to Issuance of Convertible Debentures.

        The 2006 Convertible Debentures and related derivatives outstanding at December 31, 2006 were again valued at fair value using a combination of Binomial and Black Scholes models, resulting in a decrease in the fair value of the liability of approximately $1,900,000, as a result of a decline in the Company's stock price and the conversion of approximately $156,000 of the note, which was recorded through the results of operations as a credit to adjustments to fair value of derivatives.

        In connection with this financing, we paid cash fees to a broker-dealer of $525,000 and issued a warrant to purchase 4,575,521 shares of Common Stock at an exercise price of $0.3168 per share. The initial fair value of the warrant was estimated at approximately $3,600,000 using the Black Scholes pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%, (2) expected volatility of 176%, (3) risk-free interest rate of 4.81%, and (4) expected life of 5 years. Cash fees paid, and the initial fair value of the warrant, have been capitalized as debt issuance costs and are being amortized over 36 months using the effective interest rate method.

        The following table summarizes the 2006 Convertible Debentures and discounts outstanding at December 31, 2006:

2006 Convertible debentures at fair value   $ 18,240,590  
Warrant derivative discount     (3,121,013 )
Original issue discount     (1,881,101 )
   
 
Net convertible debentures     13,238,476  
  Less current portion     (3,971,543 )
   
 
  2006 Convertible debentures and embedded derivatives-long term   $ 9,266,933  
   
 

        In the twelve months ended December 31, 2006 debentures with a book value of $156,875 were converted into 544,705 shares at $0.288 per share. These conversions resulted in an increase to

F-42



stockholders' equity of approximately $1,356,000. As a result of these conversions, approximately $79,000 of unamortized discounts related to amounts converted was charged to interest expense.

6.    CONVERTIBLE DEBENTURES—2005

        On September 15, 2005, we entered into a Securities Purchase Agreement with accredited investors for the issuance of an aggregate of $22,276,250 principal amount of convertible debentures with an original issue discount of $4,526,250 representing approximately 20.3% of the principal value. In connection with the closing of the sale of the debentures, we received gross proceeds of $17,750,000. The convertible debentures are convertible at the option of the holders into 9,685,326 shares of Common Stock at a fixed conversion price of $2.30 per share, subject to anti-dilution and other customary adjustments. In connection with the Securities Purchase Agreement, we also issued warrants to purchase an aggregate of 4,842,663 shares of our Common Stock. The term of the warrants is five years and the exercise price is $2.53 per share, subject to anti-dilution and other customary adjustments. The investors have contractually agreed to restrict their ability to convert the convertible debentures, exercise the warrants and exercise the additional investment right and receive shares of our Common Stock such that the number of shares of our Common Stock held by them and their affiliates after such conversion or exercise does not exceed 4.99% of our then issued and outstanding shares of our Common Stock.

        The Securities Purchase Agreement provides for additional investment in debentures under certain conditions. If within six months of the effective date of the Registration Statement related to registration of shares underlying the initial issuance, October 2005, the Company satisfies certain conditions set forth in the Securities Purchase Agreement, including listing of the Company on AMEX or NASDAQ Capital Markets, stock trading price in excess of conversion price, and achievement of minimum trading volumes, the Company can require the Purchasers to purchase at a second closing $11,138,125 principal amount of additional debentures for a discounted purchase price of $8,875,000. To the extent the Company has not exercised this right within the six month period, the convertible debenture holders have the right to purchase additional debentures, up to their pro rata share, less any shares required to be purchased by the Company. Twelve months following the effective date of the registration statement, any debentures not yet purchased shall be available to investors to purchase in excess of their individual pro rata share. Additional debentures issued pursuant to the agreement will have a conversion price equal to the lesser of $2.30 per share or the five day average of closing prices immediately prior to exercise of the right to additional investment of the debentures. Warrants issued pursuant to the additional investment will have an exercise price equal to the lesser of $2.53 or 110% of the conversion price. Other terms and conditions related to additional debentures issued will be the same as those specified for the debentures sold at the initial closing.

        The agreements entered into provide that we will pay certain cash amounts as liquidated damages in the event that the Company does not maintain an effective registration statement, or if we fail to timely execute stock trading activity. In addition, the agreements provide that the Company shall meet other milestones, including settlement of ACT Group litigation, and liquidation of ACT Group, as described in Note 12, formation of a majority independent Board of Directors, and merger of the Company and ACT, substantially all of which have been satisfied.

F-43



        Under the terms of the agreements, principal amounts owed under the debentures become due and payable commencing six months following closing of the transaction. At that time, and each month thereafter, we are required to either repay 1/30 of the outstanding balance owed in cash, or convert the amount due into common stock at the lesser of $2.30 per share or 85% of the prior ten days' average closing stock price, immediately preceding the redemption. The agreements also provide that we can force conversion of outstanding amounts owed under the debentures into common stock, if the Company has met conditions and milestones identified above, and, additionally, has a stock price for 20 consecutive trading days that exceeds $4.60 per share.

        Of the total proceeds from the issuance of the debentures, $5,747,297 was initially allocated to the freestanding warrants associated with the debentures based upon the fair value of the warrants. The assumptions used in the Black Scholes model for determining the initial fair value of the warrants were as follows: (1) dividend yield of 0%; (2) expected volatility of 64%, (3) risk-free interest rate of 3.99%, and (4) expected life of 5 years. In accordance with FAS 133 "Accounting for Derivative Instruments and Hedging Activities", EITF 00-19 "Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Company's Own Stock" and EITF 05-04 "The Effect of a Liquidated Damages Clause on a Freestanding Financial Instrument Subject to EITF Issue No. 00-19", the amounts allocated to the warrant represent a derivative liability that has been recorded in the accompanying balance sheet.

        The agreement included a number of other embedded derivative instruments that required bifurcation and valuation in accordance with the requirements of FAS 133, EITF 05-04 and related accounting literature. The effects of interactions between embedded derivatives are calculated and accounted for in arriving at the overall fair value of the financial instruments. The following summarizes the fair values of embedded derivatives at the transaction date of September 15, 2005 and December 31, 2006, followed by a description of the valuation methodology utilized to determine fair values:

Embedded Derivative Liability (Asset)

  Initial Fair value
September 15, 2005

  Fair value
December 31, 2006

 
Conversion Feature   $ 7,317,206   $ 1,101,414  
Anti-dilution protection     1,585,255     2,107,767  
Default provisions     96,067     46,692  
Right to provide future financing     159,960      
Company right to force conversion     (1,561,618 )   (185,091 )
   
 
 
    $ 7,596,870   $ 3,070,782  
   
 
 

        The fair value of the conversion feature derivative was estimated as an American call option using the binomial option pricing model with the following inputs: (1) closing stock price as of the valuation date of $2.20 at September 15, 2005 and $0.58 at December 31, 2006 (2) exercise price equal to $2.30 and $0.95 conversion price at September 15, 2005 and December 31, 2006, respectively (3) volatility based upon the Company's stock trading of 64% at September 15, 2005 and 162% at December 31, 2006 (4) Treasury note rates with terms commensurate with the remaining term of the Notes of 3.9% at September 15, 2005 and 4.82% at December 31, 2006 and (5) duration of the note as an amortizing

F-44



debenture of approximately 1.7 years at September 15, 2005 and 0.68 years at December 31, 2006 based upon present values.

        The fair value of the derivative for anti-dilution protection was estimated using a standard put option binomial model, adjusted for the probability of subsequent financing at prices below the principal's conversion option with the following inputs: (1) closing stock price as of the valuation date of $2.20 at September 15, 2005 and $0.58 at December 31, 2006 (2) exercise price equal to the $2.30 conversion price (3) volatility based upon the Company's stock trading of 64% at September 15, 2005 and 162% at December 31, 2006 (4) Treasury note rates with terms commensurate with the remaining term of the Notes of 3.9% and (5) duration of the note as an amortizing debenture of approximately 1.7 years at September 15, 2005 and 0.68 years at December 31, 2006 based upon present values.

Reduction of Exercise Price

        On August 24, 2006, the Company's Board of Directors agreed to reduce the exercise price of the warrants issued in connection with the 2005 debentures from $2.53 per share to $0.95 per share for approximately three days. As a result of this repricing, warrant holders with an aggregate of 4,541,672 warrants exercised their rights generating approximately $4,315,000 of cash proceeds. Warrant holders who exercised their warrants were issued replacement warrants to purchase an equivalent number of shares at an exercise price of $1.60 per share. Warrant holders who did not exercise their warrants had the conversion price of their convertible debentures reduced to $0.95. As a result of certain anti-dilution protection in the original warrant agreement, certain of the warrant holders who did not exercise their warrants received anti-dilution protection and had the number of shares covered under the warrant agreement increased to 2,135,615, and the exercise price reduced to $0.95 per share. One warrant holder waived the right to reprice their warrant for $2.53 to $0.95 and did not exercise all of their warrants. Their remaining warrants on an aggregate of 581,119 common shares remain outstanding at an exercise price of $2.53 per share.

        The Company has considered the impact of Emerging Issue Task Force statements, or EITFs 96-19—Debtor's Accounting for a Modification or Exchange of Debt Instruments, 02-4—Determining Whether a Debtor's Modification or Exchange of Debt Instruments is Within the Scope of FASB No. 15, and 05-7—Accounting for Modifications to conversion Options Embedded in Debt Instruments and Related Issues on the accounting treatment of the change in conversion price of a portion of the 2005 Convertible Debentures described in the paragraph above. EITF 96-19 states that a transaction resulting in a significant change in the nature of a debt instrument should be accounted for as an extinguishment of debt. EITF 05-7 states that if the change in the cash flows of the debt instrument plus the change in the fair value of the conversion derivative as a result of the change is greater than 10%, the change should be treated as significant and the debt is considered extinguished. The Company has concluded that the change in conversion price from $2.30 to $0.95 of a portion of the outstanding Debenture does not constitute an extinguishment of that debt.

        The fair value of the derivative for contractual default provisions was determined by taking the monthly amortization schedule, and multiplying the result by the contractual penalty of 120%. The present value of this penalty was then adjusted by the estimated probability of default for each valuation date.

        The fair value of the derivative for the investors' option to provide future financing was determined using a Black-Scholes Option Pricing Model with the following inputs: (1) The stock and exercise price was based on the maximum amount of additional investment of $8,875,000 (2) Volatility of 2% was based on the historical volatility of government and high yield bond indices (3) Risk free rate of 3.9% was based on Treasury notes and (4) time to maturity was based upon the six month option period. This option expired in September 2006 and no value has been attached to it at December 31, 2006.

        The fair value of the derivative asset related to the Company's right to force conversion was based upon a binomial option pricing model with the following inputs: (1) closing stock price at the valuation dates of $2.20 at September 15, 2005 and $0.58 at December 31, 2006 (2) exercise price of $4.60 per share which is required for the forced conversion (3) volatility based upon the Company's stock trading of 64% at September 15, 2005 and 162% at December 31, 2006 (4) Treasury note rate with terms commensurate with the remaining term of the Notes of 3.9% and (5) duration of the note as an amortizing debenture of approximately 1.7 years at September 15, 2005 and 0.68 years at December 31, 2006 based upon present values.

        During the year ended December 31, 2006, a decrease in the fair value of the embedded derivative amounts of approximately $9,073,000 was recorded through results of operations as adjustment to fair value of derivatives.

        During the year ended December 31, 2006, the Company recorded approximately $11,272,108 as Interest Expense for amortization of discounts for original issue discount, discount for warrant derivative, and other embedded derivatives identified above.

        In connection with this financing, we paid cash fees to a broker-dealer of $1,065,000 and issued a warrant to purchase 1,162,239 shares of Common Stock at an exercise price of $2.53 per share. The initial fair value of the warrant was estimated at approximately $1,379,000 using the Black Scholes pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%; (2) expected volatility of 64%, (3) risk-free interest rate of 3.99%, and (4) expected life of 5 years. Cash fees paid, and the initial fair value of the warrant, have been capitalized as debt issuance costs and are being amortized over 36 months under the effective interest rate method. Interest expense for the year ended December 31, 2006 was approximately $828,000.

        In the year ended December 31, 2006, debentures with a face value of $1,778,500 were converted into 773,043 shares at $2.30 per share. These conversions along with the pro rata portion of the conversion feature embedded derivative of approximately $718,000, resulted in an increase to stockholders' equity of approximately $2,496,000. As a result of these conversions, approximately $980,000 of unamortized discounts related to amounts converted was charged to interest expense.

7.    WARRANT DERIVATIVES

        As described more fully in Note 6—Convertible Debentures—2005, the provisions of our convertible debenture financing completed in September 2005 permit the Company to make its monthly redemption in shares rather than cash upon satisfaction of certain conditions. Under the terms of the debenture agreement, the price per share is variable dependent upon the actual closing price of the Company's common stock. Accordingly, the total number of shares to retire outstanding principal is variable and the Company can not be assured that there are adequate authorized shares to settle all contractual obligations under the debenture agreement, and other option and warrant agreements outstanding.

        In accordance with the provisions of EITF 00-19, "Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Company's Own Stock" the Company has reviewed all instruments previously recorded as permanent equity under EITF 00-19 which are described in detail in Note 10—Stockholders' Equity Transactions. As of September 15, 2005, the closing date of the convertible debenture financing, a $25,600,000 increase in the fair value of instruments previously recorded as permanent equity with a value of zero was recorded based upon fair values computed under a Black Scholes model with the following assumptions: (1) dividend yield of 0%, (2) expected volatility of 64%, (3) risk-free interest rate of approximately 3.90%, and (4) expected life and exercise prices consistent with each individual instrument.

        The accumulated fair value of these and other instruments at September 15, 2005 of approximately $27,700,000, after the increase to fair value described above, was reclassified from equity to Warrant Derivative liability in accordance with the requirements of EITF 00-19.

        At December 31, 2006, the fair value of each instrument was again computed under a Black Scholes model with the following assumptions: (1) dividend yield of 0%, (2) expected volatility of 162%, (3) risk-free interest rate ranging from approximately 4.70% to 5.10% and (4) expected life and

F-47



exercise prices consistent with each individual instrument. These calculations resulted in an aggregate value of derivative instruments of approximately $15,252,000. As a result, for the twelve months ended December 31, 2006 the Company recorded approximately $15,488,000 as a credit to adjustment to fair value of derivatives.

        The carrying value of the outstanding warrant derivatives issued in connection with the 2006 debentures was adjusted to the fair value at December 31, 2006 of approximately $2,500,000. The assumptions used in the Black Scholes model for determining the initial fair value of the warrants were as follows: (1) dividend yield of 0%; (2) expected volatility of 162%, (3) risk-free interest rate of 4.57%, and (4) expected life of 4.85 years. This resulted in a decrease in the fair value of the warrant liability of approximately $300,000 which was recorded through results of operations as a credit to adjustment to fair value of derivatives.

        The carrying value of outstanding warrant derivatives from the 2005 debentures were adjusted to their fair value at August 23, 2006, the date of the reduction in conversion price of approximately $8,000,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 167%, (3) risk-free interest rate of 4.81%, and (4) expected remaining life of 4.0 years. This resulted in an increase in the fair value of the warrant liability of approximately $1,500,000 which was recorded through results of operations as a debit to adjustments to fair value of securities. The outstanding derivatives after the repricing and exercise were then adjusted to their fair value at August 24, 2006 of approximately $3,500,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 167%, (3) risk-free interest rate of 4.81%, and (4) expected remaining life of 4.0 years. This resulted in an increase in the fair value of the warrant liability of approximately $2,000,000 which was recorded through results of operations as a debit to charges related repricing and issuance of warrants.

        The carrying value of outstanding warrant derivatives from the January 2005 Preferred financing were adjusted to their fair value at August 23, 2006 of approximately $9,400,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 167%, (3) risk-free interest rate of 4.91%, and (4) expected remaining life of 1.25 years. This resulted in an increase in the fair value of the warrant liability of approximately $6,200,000 which was recorded through results of operations as a debit to Adjustment to Fair Value of Derivatives. On August 24, 2006, the Company's Board of Directors agreed to reprice these warrants to $0.95 per share and to extend the life of the warrants by one year. The outstanding derivatives after the repricing were then adjusted to their fair value at August 24, 2006 of approximately $7,100,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 167%, (3) risk-free interest rate of 4.91%, and (4) expected remaining life of 2.25 years. This resulted in a decrease in the fair value of the warrant liability of approximately $200,000 which was recorded through results of operations as a credit to charges related to repricing and issuance of warrants.

        The fair value of warrants exercised at August 24, 2006 was recorded as equity in additional paid in capital. The fair value of replacement warrants issued to warrant holders who exercised their rights on August 24, 2006, which aggregated approximately $6,900,000, was calculated based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 167%, (3) risk-free interest rate of 4.81%, and (4) expected remaining life of 5.0 years.

F-48



        The carrying value of the remaining 2005 debenture warrant derivatives at December 31, 2006 has been adjusted to reflect fair value of approximately $1,155,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 162%, (3) risk-free interest rate of 4.70%, and (4) expected remaining life of 3.50 years. This resulted in an additional decrease in the fair value of the warrant derivative liability of approximately $302,000 which was recorded through results of operations as a credit to adjustment to fair value of derivatives.

        The carrying value of the replacement warrant derivatives at December 31, 2006 has been adjusted to reflect fair value of approximately $2,337,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0% (2) expected volatility of 162%, (3) risk-free interest rate of 4.82%, and (4) expected remaining life of 4.75 years. This resulted in a decrease in the fair value of the warrant derivative liability of approximately $574,000 which was recorded as a credit to adjustment to fair value of derivatives in the results of operations for the year ended December 31, 2006.

        The carrying value of the January 2005 financing warrant derivatives at December 31, 2006 have been adjusted to reflect fair value of approximately $2,116,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 162%, (3) risk-free interest rate of 4.82%, and (4) expected remaining life of 2.00 years. This resulted in an additional decrease in the fair value of the warrant derivative liability of approximately $725,000 which was recorded through results of operations as a credit to Adjustment to Fair Value of Derivatives.

        The carrying value of the broker dealer warrant derivatives at December 31, 2006 have been adjusted to reflect fair value of approximately $2,520,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 162%, (3) risk-free interest rate of 4.70%, and (4) expected remaining life of 4.75 years. This resulted in a decrease in the fair value of the warrant derivative liability of approximately $1,537,000 which was recorded through results of operations as a credit to Adjustment to Fair Value of Derivatives.

        The following table summarizes the components of the Adjustment to Fair Value of Derivatives which were recorded as charges to results of operations in the year ended December 31, 2006. The table summarizes by category of derivative liability the impact from market changes during the quarter, and the impact of additional investments.

8.    NOTES PAYABLE—OTHER

        On July 8, 2003, we issued a promissory note with a face amount of $272,108 to a law firm as a payment of fees due them. The note bears interest at a rate of 5% per year. The note is payable in monthly installments of $25,000, including interest. The note matured on October 1, 2003. We made payments through January 2004. At December 31, 2006 there is a remaining principal balance of $170,249, as well as accrued interest of $10,833 and accrued late fees of $65,000, included in accrued interest.

9.    RECLASSIFICATION OF EQUITY TRANSACTIONS

        As described more fully in Note 6—Convertible Debentures 2005, the provisions of our convertible debenture financing completed in September 2005 permit the Company to make its monthly redemption in shares rather than cash upon satisfaction of certain conditions. Under the terms of the debenture agreement, the price per share is variable dependent upon the actual closing price of the Company's common stock. Accordingly, the total number of shares to retire outstanding principal is variable and the Company can not be assured that there are adequate authorized shares to settle all contractual obligations under the debenture agreement, and other option and warrant agreements outstanding.

        Accordingly, in accordance with the provisions of EITF 00-19, "Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Company's Own Stock" the Company has reviewed all instruments previously recorded as permanent equity under EITF 00-19 which are described in detail in Note 10—Stockholders' Equity Transactions. As of September 15, 2005, the closing date of the convertible debenture financing, a $25,600,000 increase in the fair value of instruments previously recorded as permanent equity with a value of zero was recorded based upon fair values computed under a Black Scholes model with the following assumptions: (1) dividend yield of 0% (2) expected volatility of 64% (3) risk-free interest rate of approximately 3.9% and (4) expected life and exercise prices consistent with each individual instrument.

        The accumulated fair value of these and other instruments at September 15, 2005 of approximately $27,700,000, after the increase to fair value described above, was reclassified from equity to Warrant Derivative liability in accordance with the requirements of EITF 00-19.

        At December 31, 2005 the fair value of each instrument was again computed under a Black Scholes model with the following assumptions: (1) dividend yield of 0% (2) expected volatility of 74% (3) risk-free interest rate of approximately 4.4% and (4) expected life and exercise prices consistent with each individual instrument. These calculations resulted in an aggregate value of derivative instruments at December 31, 2005 of approximately $24,600,000. As a result, for the year ended December 31, 2005 the Company recorded approximately $3,100,000 as a credit to Adjustment to Fair Value of Derivatives. As more fully described above in Note 7—Warrant derivatives, we continue to adjust the fair value of these instruments and the effects are recognized as shown in Note 7.

10.    STOCKHOLDERS' EQUITY TRANSACTIONS

        We are authorized to issue two classes of capital stock, to be designated, respectively, Preferred Stock and Common Stock.

        On or about January 27, 2005, the Company issued 616,124 shares of its common stock and granted associated warrants to purchase 308,062 shares of common stock at a per share price of $1.27 to five holders of $500,000 aggregate principal amount of short-term promissory notes, plus interest of $23,708 in exchange for and in retirement of the notes. The fair value of the warrants was estimated at $0, using the Black Scholes option pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%; (2) expected volatility of 0%, (3) risk-free interest rate of 3.25%, and (4) expected life of 2 years.

        On or about January 15, 2005, the Company issued 17,647 shares of common stock, valued at then current fair market value based upon the value of the Company's stock of $15,000, in consideration of accounting services provided to the Company.

        During the period beginning January 3, 2005 through January 31, 2005, ACT completed a preferred unit offering in which ACT sold 4,705,890 investment units to a group of accredited investors (within the meaning of Rule 501 of Regulation D) for total consideration of $8,000,000. ACT received gross cash proceeds of $7,910,600 and the balance of $89,400 was for payment of non-Merger related legal fees which resulted in a gain on settlement of debt of approximately $87,000. The completion of the offering resulted in the issuance of 9,411,788 shares of ACT's Series A Preferred Stock and associated warrants to purchase 4,705,890 shares of common stock at a per share price of $1.27. In consideration of services rendered in connection with the preferred unit offering, ACT paid consultants to the preferred unit offering 469,247 investment units, which resulted in the issuance by the Company of 469,247 shares of Common Stock and associated warrants to purchase 234,629 shares of common stock at a per share price of $1.27, the value of the Company's stock on the date of issue. All preferred shares issued pursuant to the preferred offering were converted into common stock prior to the Merger.

11.    STOCK BASED COMPENSATION

Stock Plans

        On August 12, 2004, ACT's Board of Directors approved the establishment of the 2004 Stock Option Plan (the "2004 Stock Plan"). Stockholder approval was received on December 13, 2004. The total number of common shares available for grant and issuance under the plan may not exceed 2,800,000 shares, subject to adjustment in the event of certain recapitalizations, reorganizations and similar transactions. Common stock purchase options may be exercisable by the payment of cash or by other means as authorized by the Board of Directors or a committee established by the Board of Directors. At December 31, 2006 and 2005, ACT had granted 2,604,000 common share purchase options under the plan.

        On December 13, 2004, ACT's Board of Directors and stockholders approved the establishment of the 2004 Stock Option Plan II (the "2004 Stock Plan II "). The total number of common shares available for grant and issuance under the plan may not exceed 1,301,161 shares, subject to adjustment in the event of certain recapitalizations, reorganizations and similar transactions. Common stock purchase options may be exercisable by the payment of cash or by other means as authorized by the Board of Directors or a committee established by the Board of Directors. At December 31, 2005 and 2004, ACT had granted 1,301,161 common share purchase options under the plan.

        On January 31, 2005, the Company's Board of Directors approved the establishment of the 2005 Stock Incentive Plan (the "2005 Plan"), subject to approval of our shareholders. The total number of common shares available for grant and issuance under the plan may not exceed 9 million shares, plus an annual increase on the fist day of each of the Company's fiscal years beginning in 2006 equal to 5% of the number of shares of our common stock outstanding on the last day of the immediately preceding fiscal year, subject to adjustment in the event of certain recapitalizations, reorganizations and similar transactions. Common stock purchase options may be exercisable by the payment of cash or by other means as authorized by the Board of Directors or a committee established by the Board of Directors. At December 31, 2005, we had granted 8,907,835 common stock purchase options under the plan.

        Pursuant to the 2005 Plan, on October 26, 2006, we granted 60,000 common stock purchase options to employees and directors. The options granted have an exercise price of $0.75 per share, the market price of the Company's stock on the date of grant. Employee options vest monthly over a period of four years and director options were fully vested upon issue. The fair value of the options was estimated at $23,334 using the Black Scholes option pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%, (2) expected volatility of 162%, (3) risk-free interest rate of 5.11%, and (4) expected life of 4 years. The fair value was treated in accordance with FAS 123(R) and is being amortized over a period of four years. Since the Company vests options on the graded method, the fair value is amortized on a straight line basis which approximates the vesting schedule.

        Pursuant to the 2005 Plan, on August 18, 2006, the term of existing common stock purchase options to an employee was changed, resulting in a remeasurement of the fair value of those options. The options granted have an exercise price of $0.85 and $2.20 per share, the market price of the Company's stock on the date of grant. The fair value of the options was estimated at approximately $39,000 using the Black Scholes option pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%; (2) expected volatility of 93%, (3) risk-free interest rate of 4.59%, and (4) expected life of 6 years. The fair value of this grant was recognized in full during the period as a consulting expense.

        Pursuant to the 2005 Plan, on July 11, 2006, we granted 90,000 common stock purchase options to employees and directors. The options granted have an exercise price of $0.35 per share, the market price of the Company's stock on the date of grant. Employee options vest monthly over a period of four years and director options were fully vested upon issue. The fair value of the options was estimated at $18,128 using the Black Scholes option pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%, (2) expected volatility of 172%, (3) risk-free interest rate of 5.10%, and (4) expected life of 4 years. The fair value was treated in accordance with FAS 123(R) and is being amortized over a period of four years. Since the Company vests options on the graded method, the fair value is amortized on a straight line basis which approximates the vesting schedule.

        Pursuant to the 2005 Plan, on April 20, 2006, we granted 235,000 common stock purchase options to employees and directors. The options granted have an exercise price of $1.35 per share, the market price of the Company's stock on the date of grant. Employee options vest monthly over a period of four years and director options were fully vested upon issue. The fair value of the options was estimated at $89,343 using the Black Scholes option pricing model. The assumptions used in the Black

Scholes model are as follows: (1) dividend yield of 0%, (2) expected volatility of 78%, (3) risk-free interest rate of 5.10%, and (4) expected life of 6 years. The fair value was treated in accordance with FAS 123(R) and is being amortized over a period of four years. Since the Company vests options on the graded method, the fair value is amortized on a straight line basis which approximates the vesting schedule.

        Pursuant to the 2005 Plan, on January 26, 2006, we granted 230,000 common stock purchase options to employees and directors. The options granted have an exercise price of $2.04 per share, the market price of the Company's stock on the date of grant. Employee options vest monthly over a period of four years and director options were fully vested upon issue. The fair value of the options was estimated at $314,328 using the Black Scholes option pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%, (2) expected volatility of 74%, (3) risk-free interest rate of 4.38%, and (4) expected life of 6 years. The fair value was treated in accordance with FAS 123(R) and is being amortized over a period of four years. Since the Company vests options on the graded method, the fair value is amortized on a straight line basis which approximates the vesting schedule.

        Pursuant to the 2005 Plan, on November 16, 2005, we granted 205,000 common stock purchase options to employees. The options granted have an exercise price of $2.11 per share, the market price of the Company's stock on the date of grant and vest over periods not exceeding 4 years. The fair value of the options was estimated at $250,793 using the Black Scholes option pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%; (2) expected volatility of 74%, (3) risk-free interest rate of 4.35%, and (4) expected life of 4 years.

        Pursuant to the 2005 Plan, on November 16, 2005, we granted 10,000 common stock purchase options to consultants. The options granted have an exercise price of $2.11 per share, the market price of the Company's stock on the date of grant and vest over periods not exceeding 2 years. The fair value of the options was estimated at $8,035 using the Black Scholes option pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%; (2) expected volatility of 65%, (3) risk-free interest rate of 4.13%, and (4) expected life of 2 years. This initial estimate of fair value will be expensed over the consulting period. In addition to this initial estimate of fair value, the Company calculates additional periodic expense based upon options which vest during the period. This amount, plus amortization of initial fair value, resulted in a total charge of $8,489 in the twelve months ended December 31, 2005.

        Pursuant to the 2005 Plan, on September 15, 2005, we granted 500,000 common stock purchase options to employees.

The options have an exercise price of $2.48 per share, the market price of the Company's stock on the date of grant and vest over periods not exceeding 2 years. The fair value of the options at the date of grant was estimated at $170,162 for the consultant options and $41,886 for the director options using the Black Scholes option pricing model. The assumptions used in the Black Scholes model are as follows: (1) dividend yield of 0%; (2) expected volatility of 65%, (3) risk-free interest rate of 4.13%, and (4) expected life of 2 years. This initial estimate of fair value will be expensed over the option vesting period. In addition to this initial estimate of fair value, the Company calculates additional periodic expense based upon options which vest during the period.

        As of December 31, 2006 and December 31, 2005, there were 7,503,665 and 6,320,961 exercisable options outstanding at a weighted average exercise price per share of $0.61 and $0.57, respectively, and with a weighted average life of 8.40 years and 9.02 years respectively. During the period, 415,833 options were forfeited. Options exercised during the period had no intrinsic value. The aggregate intrinsic value of all options vested and expected to vest is approximately $1.2 million. All fully vested options in the Company are exercisable.

        Options exercised during the period had no intrinsic value. The aggregate intrinsic value of all options vested and expected to vest is approximately $1.2 million. All fully vested options in the Company are exercisable.

        The fair value of all options vested during the years ended December 2005 and 2006 was $505,180 and $522,516 respectively.

        The following table illustrates the effect on net income and earnings per share for the period ended December 31, 2005 if the Company had applied the fair value recognition provisions of FAS 123 to options granted under the company's stock option plans in all periods presented. For purposes of

        The above pro forma disclosure is provided for 2005 because employee stock options were not accounted for using the fair-value method during that period.

        For the twelve months ended December 31, 2006, a charge of approximately $180,000 was recorded through results of operations as Research and Development expense related to share based compensation. For the twelve months ended December 31, 2006, a charge of approximately $169,000 was recorded through results of operations as General and Administrative expense related to share based compensation. These amounts were calculated using a pre-vesting forfeiture rate of 13%, based on historical employee turnover and forfeiture data.

        A summary of the status of unvested employee stock options as of December 31, 2006 and changes during the period then ended, is presented below:

12.    ACT GROUP SETTLEMENT

        On September 14, 2005, we entered into a Settlement Agreement ("Settlement Agreement") with Gary D. Aronson and John S. Gorton ("Plaintiffs") and our majority shareholder, A.C.T. Group, Inc., a Delaware corporation that has since filed a certificate of dissolution in the state of Delaware ("ACT Group"), Advanced Cell, Inc., a Delaware Corporation, Michael D. West, Gunnar L. Engstrom, William M. Caldwell, IV, Anthem Venture Partners and Greg Bonfiglio (referred to collectively with the Company as the "Defendants"). The Settlement Agreement resolved certain disputes relating to the

F-58



litigation entitled Gary D. Aronson and John Gorton v. A.C.T. Group, Inc., Advanced Cell Technology, Inc., Michael D. West, and Gunnar L. Engstrom which was pending in Commonwealth of Massachusetts Superior Court, Worcester, C.A. No. 040523B and two companion Contempt Complaints filed by the Plaintiffs against certain of the Defendants, including the Company. The Settlement Agreement extinguished in full ACT Group's obligations and indebtedness to Plaintiffs, and Plaintiffs dismissed pending claims and actions.

        We analyzed the $600,000 of convertible promissory notes payable and related warrants issued by the Company in connection with this settlement, and determined that the warrants should be recorded as free standing warrant derivative liabilities, and the conversion option and anti-dilution provisions represent embedded derivative instruments under the provisions of FAS 133. Accordingly, we separately valued these instruments and recorded discounts offsetting Notes Payable—Other.

        In August 2006, we repaid in full the convertible promissory notes payable. This cash payment, along with accrued interest and costs, resulted in payment in full of the outstanding notes payable balances and in a loss on extinguishment of approximately $263,000. As a result of repaying in full the outstanding notes payable, the fair value of the embedded derivative for the conversion option of approximately $14,000 was charged to adjustment to fair value of derivatives.

        In September 2006, the Company received notice of exercise of the warrants issued as part of the Settlement Agreement noted above. In accordance with anti-dilution provisions in the warrant and the issuance of 2006 convertible debentures described in Note 5, the exercise resulted in issuance of approximately 3,200,000 shares of common stock. The warrants were adjusted to their fair value at September 5, 2006 of approximately $185,000 based upon a Black Scholes calculation as follows: (1) dividend yield of 0%, (2) expected volatility of 175%, (3) risk-free interest rate of 4.71%, and (4) expected remaining life of 2.6 years. This resulted in an increase in the fair value of the warrant liability of approximately $18,000 which was recorded through results of operations as a debit to Adjustment to Fair Value of Derivatives.

13.    COMMITMENTS AND CONTINGENCIES

        We are a party to a research collaboration agreement and license agreement with the University of Massachusetts, as amended from time to time (the "UMass License"). Under the UMass License, we were granted certain exclusive rights to license and sublicense certain products and services invented as part of the collaborative effort. The term of the UMass License extends to the later of the expiration of the related patents currently 2021, or April 16, 2006. We are required to pay royalties ranging from 2.5% to 4.5% of net sales of licensed products and services, as defined. Minimum royalties of $45,000 per year must be paid to UMass. For 2005 and 2004, we have paid only the minimum royalty required. Additionally, we are required to pay sublicense fees of 18% for sublicense income, as defined. We are required to spend a minimum annual amount of $200,000 on research and development.

        In May 2006 we entered into exclusive and non-exclusive sublicense agreements with a company whereby we are the licensee of certain of their technology and intellectual property for a cash payment of $300,000. The agreement requires we pay minimum annual royalties of $25,000 per annum for 2006, $37,500 for 2007 and $50,000 each year thereafter through the term of the agreement. The initial

F-59



license fees paid have been capitalized and will be amortized over the life of the underlying intellectual property, estimated to be approximately ten years.

        During 2004, we entered into license agreements with two parties as licensor, the terms of which provide for the initial payment of the license fee through an aggregate of six promissory notes totaling $1,400,000. The notes mature as follows: $333,333 on December 1, 2005; $666,667 on December 1, 2006; and $400,000 on June 1, 2007. There is no stated interest rate for $1,000,000 of notes, the remaining $400,000 bear interest at 10% per year, but only if the notes are not paid at maturity. Because of the uncertainty of the ultimate collection of the principal amount of the notes, they have not been recorded in the financial statements and will not be recorded until their collectibility is reasonable assured.

        The Company entered into a lease for office and laboratory space in Massachusetts commencing December, 2004 and expiring April, 2010 and for office space in California commencing November, 2005 and expiring May 2008. Annual minimum lease payments are as follows:

2007   568,509
2008   386,311
2009   246,146
2010   83,400
   
Total   1,284,366
   

        During 2005, the Company entered into a lease for laboratory equipment commencing November 29, 2005 and expiring May 31, 2008. Annual minimum lease payments are as follows:

2007     87,964  
2008     36,655  
   
 
      124,619  
Imputed interest     (15,054 )
   
 
Net asset value     109,565  
Less current portion     (77,594 )
   
 
Long-term commitment under capital lease   $ 31,971  
   
 

        Rent expense recorded in the financial statements for the years ended December 31, 2006 and 2005 was $1,387,155 and $461,155, respectively.

        We have entered into employment contracts with certain executives and research personnel. The contracts provide for salaries, bonuses and stock option grants, along with other employee benefits. The employment contracts generally have no set term and can be terminated by either party. There is a provision for payments of three months to one year of annual salary as severance if we terminate a contract without cause, along with the acceleration of certain unvested stock option grants.

14.    LEGAL PROCEEDINGS

        University of Massachusetts v. James M. Robl and Phillippe Collas, Massachusetts Superior Court (Suffolk County). The University of Massachusetts, referred to as UMass, filed a complaint on February 22, 2004 in the Superior Court (Suffolk County) for the Commonwealth of Massachusetts. A decision adverse to UMass in this litigation could have had a materially adverse effect on our business. The complaint alleged the misappropriation by the defendants of valuable inventions in the fields of animal cloning and cell reprogramming, made by the defendants at UMass and with UMass support, that are exclusively licensed to ACT by UMass. The complaint included counts for declaratory judgment, breach of contract seeking specific performance, injunctive relief and damages, intentional interference with contract and prospective contractual relations, conversion, breach of duty, and breach of the covenant of good faith and fair dealing. ACT successfully intervened in the litigation to protect its interests. In May 2006 the parties to the litigation reached a settlement agreement, and this case was dismissed during the second quarter.

        University of Massachusetts and Advanced Cell Technology, Inc. v. Roslin Institute (Edinburgh), Geron Corporation and Exeter Life Sciences, Inc., U.S. District Court for the District of Columbia. We filed an action on February 18, 2005 in the U.S. District Court for the District of Columbia. We brought this action under 35 U.S.C. 146 to reverse the decision of the Board of Patent Appeals and Interferences regarding a patent to a method of cloning non-human animals. The patent, U.S. Patent No. 5,945,577, is licensed by the University of Massachusetts exclusively to us.

        University of Massachusetts and Advanced Cell Technology, Inc. v. Roslin Institute (Edinburgh), Geron Corporation and Exeter Life Sciences, Inc., U.S. District Court for the District of Columbia. We filed an action on April 7, 2005 in the U.S. District Court for the District of Columbia. We brought this action under 35 U.S.C. 146 to reverse the decision of the Board of Patent Appeals and Interferences regarding a patent to a method of creating embryonic stem cells. The patent, U.S. Patent No. 6,235,970, is licensed by the University of Massachusetts exclusively to us.

        On August 30, 2006, the Company entered into a License and Settlement Agreement between the Company, UMass and Start Licensing, Inc. ("Start") relating to the settlement of the patent interference actions most recently described above ("Geron-Related Proceedings"). The terms of the License and Settlement Agreement include an initial payment to the Company of $500,000 and milestone payments to the Company of up to $750,000. In addition, Start, Geron Corporation and Roslin Institute ("Roslin") each agree not to sue the Company under certain patent applications owned by Roslin. In exchange, the Company and the University agreed to dismiss their appeal in the Geron-Related Proceedings with prejudice, transfer control of related University patents to Start and pay certain legal fees. Under the terms of the settlement agreement, the Company retained its rights under the University patents in the human field.

15.    INCOME TAXES

        The Company accounts for income taxes in accordance with Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes". FAS No. 109 requires the Company to provide a net deferred tax asset/liability equal to the expected future tax benefit/expense of temporary reporting differences between book and tax accounting methods and any available operating loss or tax credit

F-61



carryforwards. The Company has available at December 31, 2006, operating loss carryforwards of approximately $43,000,000, which may be applied against future taxable income and which expire in various years through 2024. At December 31, 2005, the company had operating loss carryforwards of approximately $23,000,000. The increase in carryforwards for the year ended December 31, 2006 is approximately $20,000,000. If certain substantial changes in the Company's ownership should occur, there will be an annual limitation on the amount of net operating loss carryforwards which can be utilized.

        The amount of and ultimate realization of the benefits from the operating loss carryforwards for income tax purposes is dependent, in part, upon the tax laws in effect, the future earnings of the Company, and other future events, the effects of which cannot be determined. Because of the uncertainty surrounding the realization of the loss carryforwards, the Company has established a valuation allowance equal to the tax effect of the loss carryforwards and, therefore, no deferred tax asset has been recognized for the loss carryforwards. A reconciliation of the statutory Federal income tax rate and the effective income tax rate for the years ended December 31, 2006 and 2005 follows:

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

Item 24. Indemnification of Directors and Officers

        Article Ten of our certificate of incorporation provides that, to the fullest extent permitted by the Delaware General Corporation Law, a director of the corporation shall not be liable to the corporation or its stockholders for monetary damages for breach of his or her fiduciary duty as a director. Section 102 of the Delaware General Corporation Law allows a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit.

        Article Ten of our certificate of incorporation also provides that the corporation shall indemnify, in the manner and to the fullest extent permitted by the Delaware General Corporation Law, any person (or the estate of any person) who is or was a party to, or is threatened to be made a party to, any threatened, pending or completed action, suit or proceeding, by reason of the fact that such person is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise. Section 145 of the Delaware General Corporation Law provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal proceeding, if such person had no reasonable cause to believe his conduct was unlawful; provided that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that such indemnification is proper under the circumstances.

        Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.

Item 25. Other Expenses of Issuance and Distribution
