STATEMENT PURSUANT TO RULE 13d-1
OF THE
GENERAL RULES AND REGULATIONS
UNDER THE
SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

Item 1. Security and Issuer.

        Item 1 is amended and restated to read as follows:

        This Amendment No. 6 to Schedule 13D (this "Statement") relates to the Common Stock, par value $0.01 per share (the "Shares"), of Next Level Communications, Inc., a Delaware corporation (the "Company") and amends and supplements all information contained in the initial statement on Schedule 13D (the "Initial Statement") filed on January 14, 2000, as amended by Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4 and Amendment No. 5 filed on June 15, 2001, March 6, 2002, April 30, 2002, July 3, 2002 and October 7, 2002, respectively, by Motorola, Inc., a Delaware corporation ("Motorola").

        The Initial Statement amended and supplemented all information contained in an initial statement on Schedule 13D ("GI Schedule 13D") filed on November 22, 1999 by General Instrument Corporation, a Delaware corporation ("General Instrument"), the Voting Trust and the Trustee (each as defined and identified in the GI Schedule 13D) in which Shares were previously reported as beneficially owned by General Instrument. On January 5, 2000, pursuant to an agreement and plan of merger (the "Agreement and Plan of Merger"), dated September 14, 1999, General Instrument merged with and into Lucerne Acquisition Corp. ("Lucerne"), a Delaware corporation and a wholly-owned subsidiary of Motorola (the "Merger"). As a result of the Merger the separate corporate existence of Lucerne ceased, General Instrument continued as the surviving corporation as a wholly-owned subsidiary of Motorola, the Voting Trust was terminated and Motorola became the sole beneficial owner of the Shares of the Company held by General Instrument, with the sole voting and investment power with respect to such Shares. Consequently, since the date of the Merger Motorola has assumed the reporting obligations with respect to such Shares. Unless otherwise indicated, capitalized terms used but not defined herein shall have the same meanings assigned to such terms in the GI Schedule 13D and are incorporated herein by reference.

        The Company's principal executive offices are at 6085 State Farm Drive, Rohnert Park, California 94928.


Item 2. Identity and Background.

        Item 2 is amended and restated to read as follows:

        The names, business addresses and present principal occupations or employment of the directors and executive officers of Motorola are set forth in the attached Appendix 1, which is incorporated

3


herein by reference. To the best of Motorola's knowledge, except as noted on Appendix 1, all directors and executive officers of Motorola are citizens of the United States.


Item 3. Source and Amount of Funds or Other Consideration.

        Item 3 is amended and restated to read as follows:

        In connection with the Merger described above, each outstanding share of General Instrument common stock was exchanged for 0.575 shares of Motorola common stock, with cash in lieu of any fractional Motorola shares that former General Instrument stockholders would have otherwise received. As a result of the Merger, Motorola became the sole beneficial owner of the 64,103,724 Shares of the Company held by General Instrument, with the sole voting and investment power with respect to such Shares.

        On May 16, 2001, Motorola and the Company entered into a $60 million credit agreement (the "Credit Agreement"). Under the terms of the Credit Agreement, the Company granted Motorola warrants for up to 7,500,000 Shares (the "May Warrants"), all with an exercise price of $7.39 per share. The May Warrants expire on May 15, 2006 and are exercisable in varying increments described below in Item 4.

        On October 24, 2001, Motorola entered into: i) a Guarantee pursuant to which Motorola will guarantee the Company's $20 million mortgage loan obligation to a third party; and ii) an Environmental Indemnity Agreement in favor of the third party relating to real estate security. In exchange for Motorola entering into such agreements, the Company granted Motorola warrants for an additional 400,000 Shares ("Warrant No. 10"), all with an exercise price of $3.82 per share. Warrant No. 10 is currently exercisable and expires on October 23, 2006.

        On December 11, 2001, pursuant to an Amendment to the Credit Agreement (the "December 11, 2001 Amendment") between Motorola and the Company, Motorola agreed to provide an additional $20 million of loans ("$20 million tranche") to the Company. Under the terms of the December 11, 2001 Amendment, the Company granted to Motorola a convertible promissory note ("Convertible Promissory Note") that was convertible, at the option of Motorola, into Shares or other securities of the Company upon the same terms as would be offered to other investors in the Company's next future equity financing in excess of $15 million. If no such Company financing occurred and either (i) the Company delivered a notice of prepayment of this $20 million tranche or (ii) this $20 million tranche would mature within thirty days, then Motorola, at its option, could convert the outstanding principal and interest under the Convertible Promissory Note into Shares at a rate of $4.29 per share, subject to customary anti-dilution protection provisions. This $20 million tranche could not be prepaid while there was outstanding any other loans under the Credit Agreement, as amended. The Convertible Promissory Note was cancelled in exchange for receipt of shares of Series A-1 Convertible Preferred Stock of the Company pursuant to the terms of a Securities Purchase Agreement dated as of June 25, 2002 between the Company and Motorola, as described below.

        As additional consideration for entering into the December 11, 2001 Amendment, the Company granted Motorola an additional warrant to acquire 2,500,000 Shares ("Warrant No. 11"), all with an

4



exercise price of $4.29 per share. Warrant No. 11 is currently exercisable and expires on December 10, 2006.

        On February 21, 2002, Motorola and the Company entered into a Securities Purchase Agreement (the "February 2002 Securities Purchase Agreement") whereby Motorola purchased 6,912,442 shares of the Series A Convertible Preferred Stock of the Company ("Series A Preferred") at a per share purchase price of $4.34, for a total purchase price of approximately $30 million. Each share of Series A Preferred is convertible into two shares of the Company's common stock; is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of Series A Preferred; and is entitled to a liquidation preference of $10.85 in the event of insolvency or dissolution of the company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of Company's assets outside the ordinary course of business. Each holder of Series A Preferred may vote its shares on an as-converted basis. In addition, certain material actions require the consent of a majority of the holders of the Series A Preferred. Finally, a majority of the holders of the Series A Preferred were able to call for redemption of the Series A Preferred on or after February 19, 2007 at a per share redemption price of $5.21. On December 18, 2002 the Company amended the terms of the outstanding Series A Preferred as discussed below. As a result of the amendment the majority holders of the Series A Preferred may no longer call for redemption of the Series A Preferred and the events under which a Series A Preferred holder is entitled to a liquidation preference have been amended. In addition, on February 21, 2002, the Company granted Motorola a warrant for 3,456,221 Shares with an exercise price of $2.17 per share ("Warrant No. Series A 001") and a warrant for 3,456,221 Shares with an exercise price of $2.60 per share ("Warrant No. Series A 002"). The warrants are currently exercisable and expire on February 19, 2007.

        Pursuant to a commitment letter dated March 29, 2002 between Motorola and the Company (the "Commitment Letter"), Motorola agreed to provide an additional $35 million of funding (the "Financing Facility") to the Company. The Commitment Letter provided that Motorola had the option at the time of any drawdown thereunder by the Company of the Financing Facility to either treat such drawdown as (a) an increase in the aggregate principle amount of convertible secured debt owed by the Company to Motorola under the Credit Agreement as represented by the Convertible Promissory Note, or (b) as an additional preferred stock investment with terms (other than price) substantially identical to those contained in the February 2002 Securities Purchase Agreement. In either instance, the Company would grant Motorola warrant coverage consistent in amount with that given in connection with either the Convertible Promissory Note or the February 2002 Securities Purchase Agreement (the "March 2002 Warrants"). The pricing of any preferred stock investment or of any of the March 2002 Warrants would be the lower of the average of the closing prices of the Company's Shares for either (a) the five days prior to March 29, 2002, or (ii) five days prior to the particular drawdown by the Company. The Company drew down: (i) $13 million and (ii) $10 million, respectively, under the Financing Facility for shares of Series A-1 Convertible Preferred Stock of the Company pursuant to the terms of Securities Purchase Agreements between the Company and Motorola dated as of June 25, 2002 and September 26, 2002, respectively, as described below. The Company drew down the remaining $12 million under the Financing Facility on December 18, 2002 for shares of Series A-2 Convertible Preferred Stock of the Company pursuant to the terms of a Securities Purchase Agreement between the Company and Motorola dated December 18, 2002 as described below. The Convertible Promissory Note was cancelled on June 25, 2002 as discussed below and therefore after June 25, 2002 Motorola no longer had the option to treat a drawdown under the Financing Facility as described in (a) above.

        Pursuant to a letter to the NASD dated April 22, 2002 (the "Letter of Certification"), Motorola agreed that, within ten days of the execution of such letter, Motorola would execute and deliver to the Company a waiver pursuant to which it would, in its capacity as holder of the Company's Series A Preferred, agree through November 1, 2002: (i) to waive its right of redemption under Section B(2) of the Certificate of Designation of the Company's Series A Preferred in the event of a change of control

5



or sale of a material portion of the Company's assets and (ii) not to transfer the Series A Preferred unless the transferee agrees in writing to be bound by the foregoing waiver. Pursuant to the terms of a Securities Purchase Agreement between the Company and Motorola dated as of September 26, 2002 as described below this waiver was extended to April 1, 2003. Pursuant to the terms of a Securities Purchase Agreement between the Company and Motorola dated December 18, 2002 as described below, the amendment of the terms of the Series A Preferred on December 18, 2002, as also described below, supercedes this waiver. As a result this waiver is no longer in effect.

        In addition, Motorola agreed in the Letter of Certification that it would undertake that to the extent necessary for the Company to achieve compliance with all current Nasdaq National Market listing requirements (including, when applicable, the stockholders' equity requirement) by June 30, 2002 and for the remainder of fiscal year 2002, it would: (a) modify all or a portion of its Financing Facility by amending the terms of the Financing Facility such that any drawdowns by the Company under the Financing Facility will be in exchange for the issuance of Series A Preferred subject to the waiver of the change of control redemption right described above; (b) if the modification to the Financing Facility contemplated by clause (a) is not sufficient for the Company to maintain compliance with the listing requirements, convert up to $6 million of the Company's existing indebtedness to Motorola to equity such that the converted indebtedness will be classified as equity on the Company's balance sheet on a going forward basis; and (c) if necessary to comply with the Nasdaq National Market's stockholders' equity requirement once it becomes mandatory in the fourth quarter of 2002, further amend the terms of the Series A Preferred such that it would be classified as equity on the Company's balance sheet on a going forward basis for purposes of the stockholders' equity listing requirement. The Letter of Certification also provided that the foregoing shall not limit the ability of Motorola and the Company to cause the Company to achieve and maintain compliance with all Nasdaq National Market listing requirements pursuant to reverse stock splits or other restructuring of Series A Preferred or indebtedness of the Company to Motorola in a manner so that such preferred stock or indebtedness would be classified as equity on the Company's balance sheet. Motorola has taken the necessary actions as agreed to in the Letter of Certification.

        As consideration for the Letter of Certification to NASD, the Company issued to Motorola the following warrants, exercisable five years from the date of the NASD letter all with an exercise price of $2.00 per share and expiring on April 22, 2012: (i) 100,000 warrants for the Letter of Certification and the overall contingent re-structuring; and (ii) 300,000 warrants for the waiver of the redemption in the event of a change of control relating to the $30 million Series A, collectively (the "A 003 Warrant").

        On June 25, 2002, Motorola and the Company entered into a Securities Purchase Agreement (the "June 2002 Securities Purchase Agreement") whereby Motorola purchased shares of the Series A-1 Redeemable Convertible Preferred Stock of the Company (the" Series A-1 Preferred"). Pursuant to the terms of the June 2002 Securities Purchase Agreement, Motorola purchased 277,311 shares of Series A-1 Preferred ("June 2002 Series A-1 Preferred") at a per share purchase price of $119.00, for a total purchase price of approximately $33 million. The total purchase price consisted of (i) the cancellation of the $20 million under the Convertible Promissory Note issued by the Company to Motorola in exchange for receipt of shares of June 2002 Series A-1 Preferred and (ii) cash in the amount of $13 million representing a drawdown on the Financing Facility. Each share of June 2002 Series A-1 Preferred is initially convertible into 100 shares of the Company's common stock and is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of Series A-1 Preferred. Holders of Series A-1 Preferred may vote their shares together with holders of Common Stock on an as-converted to common stock basis, and certain material actions require the consent of holders of a majority of the Series A-1 Preferred. In addition each share of June 2002 Series A-1 Preferred is entitled to a liquidation preference of $297.50 per share in the event of insolvency or dissolution of the Company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of Company's assets

6



outside the ordinary course of business. Motorola had waived its right to receive the liquidation preference in the event of a change of control or sale of a material portion of the Company's assets if such event occurred prior to April 1, 2003. Pursuant to the terms of a Securities Purchase Agreement between the Company and Motorola dated December 18, 2002 as described below, the amendment of the terms of the Series A-1 Preferred on December 18, 2002, as described below, supercedes this waiver. As a result this waiver is no longer in effect. Lastly, holders of a majority of the Series A-1 Preferred were able to require the Company to redeem the Series A-1 Preferred on or after June 25, 2007. The per share redemption price of the June 2002 Series A-1 Preferred was $142.80. On December 18, 2002 the Company amended the terms of the outstanding Series A-1 Preferred as discussed below. As a result of the amendment the majority holders of the Series A-1 Preferred may no longer call for redemption of the Series A-1 Preferred and the events under which a Series A-1 holder is entitled to a liquidation preference have been amended. On June 25, 2002 in connection with the issuance of the June 2002 Series A-1 Preferred, the Company granted Motorola: (i) a warrant to purchase 6,008,403 shares of the Company's common stock which is currently exercisable with an exercise price of $1.19 per share and expiring on June 24, 2007 ("Warrant A-1 001") and (ii) a warrant to purchase 330,000 shares of the Company's common stock which is exercisable after June 25, 2007 with an exercise price of $2.00 per share expiring on June 24, 2012 ("Warrant A-1 002").

        On September 26, 2002, Motorola and the Company entered into a Securities Purchase Agreement (the "September 2002 Securities Purchase Agreement") whereby Motorola purchased shares of the Series A-1 Preferred Stock. Pursuant to the terms of the September 2002 Securities Purchase Agreement, Motorola purchased 236,559 shares of Series A-1 Preferred (the "September 2002 Series A-1 Preferred") at a per share purchase price of $93.00, for a total purchase price of approximately $22 million. The total purchase price consisted of (i) the cancellation of $12 million under the Credit Agreement, dated as of May 16, 2001 between the Company and Motorola, as amended, and (ii) cash in the amount of $10 million representing a drawdown on the Financing Facility. Each share of September 2002 Series A-1 Preferred is initially convertible into 100 shares of the Company's common stock and is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of September 2002 Series A-1 Preferred. Holders of Series A-1 Preferred may vote their shares together with holders of Common Stock on an as-converted to common stock basis, and certain material actions require the consent of holders of a majority of Series A-1 Preferred. Each share of September 2002 Series A-1 is entitled to a liquidation preference of $232.50 per share in the event of insolvency or dissolution of the Company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of the Company's assets outside the ordinary course of business. Motorola had waived its right to receive the liquidation preference in the event of a change of control or sale of a material portion of the Company's assets if such event occurred prior to April 1, 2003. Pursuant to the terms of a Securities Purchase Agreement between the Company and Motorola dated December 18, 2002 as described below, the amendment of the terms of the Series A-1 Preferred on December 18, 2002, as described below, supercedes this waiver. As a result this waiver is no longer in effect. Lastly, holders of a majority of the Series A-1 Preferred were able to require the Company to redeem the Series A-1 Preferred on or after June 25, 2007. The per share redemption price of the September 2002 Series A-1 Preferred was $111.60. On December 18, 2002 the Company amended the terms of the outstanding Series A-1 Preferred as discussed below. As a result of the amendment the majority holders of the Series A-1 Preferred may no longer call for redemption of the Series A-1 Preferred and the events under which a Series A-1 holder is entitled to a liquidation preference have been amended. On September 26, 2002 in connection with the issuance of the September 2002 Series A-1 Preferred, the Company granted Motorola (i) a warrant to purchase 220,000 shares of the Company's common stock which is exercisable after September 26, 2007 with an exercise price of $2.00 per share ("Warrant No. A-1 003") and (ii) a warrant to purchase 5,913,978 shares of the Company's common stock which is

7



currently exercisable with an exercise price of $0.93 per share ("Warrant No. A-1 004"). The warrants expire on September 25, 2012 and September 25, 2007, respectively.

        On October 22, 2002, pursuant to an Amendment to the Credit Agreement (the "October 22, 2002 Amendment"), between Motorola and the Company, Motorola agreed to extend the maturity date of the Credit Agreement from May 16, 2003 to May 16, 2006. Under the terms of the October 22, 2002 Amendment, the Company granted to Motorola a warrant for 3,000,000 shares all with a n exercise price of $0.76 per share (Warrant No. 12"). Warrant No. 12 is currently exercisable and expires on October 21, 2007.

        On December 18, 2002, Motorola and the Company entered into a Securities Purchase Agreement (the "December 2002 Securities Purchase Agreement") whereby Motorola purchased shares of the Series A-2 Convertible Preferred Stock ("Series A-2 Preferred"). Pursuant to the terms of the December 2002 Securities Purchase Agreement, Motorola purchased 26,506 shares of Series A-2 Preferred (the "December 2002 Series A-2 Preferred") at a per share purchase price of $830.00, for a total purchase price of approximately $22 million. The total purchase price consisted of (i) the cancellation of $10 million under the Credit Agreement, dated as of May 16, 2001 between the Company and Motorola, as amended, and (ii) cash in the amount of $12 million representing a drawdown on the Financing Facility. Each share of December 2002 Series A-2 Preferred is initially convertible into 1,000 shares of the Company's common stock; is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of December 2002 Series A-2 Preferred; and is entitled to a liquidation preference of $2,075.00 per share in the event of insolvency or dissolution of the Company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of the Company's assets outside the ordinary course of business. Holders of Series A-2 Preferred may vote their shares together with holders of Common Stock and Series A-1 Preferred on an as-converted to common stock basis, and certain material actions require the consent of holders of a majority of Series A-1 and A-2 Preferred. In connection with the issuance of the December 2002 Series A-2 Preferred, the Company granted Motorola (i) a warrant to purchase 220,000 shares of the Company's common stock which is exercisable after December 18, 2007 with an exercise price of $2.00 per share ("Warrant No. A-2 001") and (ii) a warrant to purchase 7,951,807 shares of the Company's common stock which is currently exercisable with an exercise price of $0.83 per share ("Warrant No. A-2 002"). The warrants expire on December 17, 2012 and December 17, 2007, respectively.

        Also on December 18, 2002 the Company amended the terms of its outstanding Series A Preferred and Series A-1 Preferred to: i) remove the provision allowing for redemption at the option of the holder after February 19, 2007 in the case of the Series A Preferred and after June 25, 2007 in the case of the Series A-1 Preferred; and ii) amend the events under which a holder of the Series A Preferred or Series A-1 Preferred is entitled to a liquidation preference. As amended, the Series A Preferred and Series A-1 Preferred contain substantially identical terms as the Series A-2 Preferred.


Item 4. Purpose of Transaction.

        Item 4 is amended and restated to read as follows:

        Beneficial ownership of the 64,103,724 Shares was acquired by Motorola as part of the Merger. Reference is made to Motorola's Registration Statement on Form S-4 (File No. 333-88735) for more information regarding the Merger, including the background and reasons therefore. Prior to the Merger, beneficial ownership of the 64,103,724 Shares was with General Instrument. Reference is made to the GI Schedule 13D for more information regarding beneficial ownership of such Shares by General Instrument, the Voting Trust and the Trustee.

        Prior to the Merger, the 64,103,724 Shares were held in the Voting Trust, which was terminated upon the Merger. Following such termination, such Shares were registered to General Instrument.

8



Pursuant to the Corporate and Intercompany Agreement described in Item 6 below, upon termination of the Voting Trust, the Company's board of directors took action to appoint four Motorola employees as Company directors. As of September 30, 2002, the only Motorola employees who serve as Company directors are Eugene Delaney and Gray Benoist.

        On May 16, 2001, Motorola and the Company entered into the Credit Agreement. Under the terms of the Credit Agreement, the Company granted Motorola the May Warrants. All the May Warrants have an exercise price of $7.39 per share and expire on May 15, 2006. The May Warrants are exercisable in varying increments as follows: a) on May 16, 2001, (the "Effective Date") of the Credit Agreement, warrants for 1,500,000 Shares became exercisable; b) on May 18, 2001, warrants for an additional 1,500,000 Shares became exercisable when the Company's cumulative borrowing under the Credit Agreement exceeded $30 million; c) on June 20, 2001, warrants for an additional 750,000 Shares become exercisable when the Company's cumulative borrowing under the Agreement exceeded $40 million; d) on June 27, 2001, warrants for an additional 750,000 Shares become exercisable when the Company's cumulative borrowing under the Agreement exceeded $50 million; and e) warrants for an additional 3,000,000 Shares become exercisable in 1,000,000 increments on May 17, 2002, November 15, 2002 and February 17, 2003 respectively, unless prior to those dates the Company's borrowings under the Credit Agreement have been repaid in full and the Credit Agreement has been terminated. On May 30, 2002, pursuant to the terms of an Amendment to the Credit Agreement (the "May 30, 2002 Amendment") between Motorola and the Company, the exercise date of two of the May Warrants for 1,000,000 Shares each, exercisable on November 15, 2002 and February 17, 2003, respectively, was changed to May 30, 2002.

        On October 24, 2001, Motorola entered into: i) a Guarantee pursuant to which Motorola will guarantee the Company's $20 million mortgage loan obligation to a third party; and ii) an Environmental Indemnity Agreement in favor of the third party relating to real estate security. In exchange for Motorola entering into such agreements, the Company granted Motorola Warrant No. 10 for an additional 400,000 Shares, with an exercise price of $3.82 per share. Warrant No. 10 is currently exercisable and expires on October 23, 2006.

        Pursuant to the December 11, 2001 Amendment to the Credit Agreement, Motorola agreed to provide an additional $20 million tranche to the Company. Under the terms of the December 11, 2001 Amendment, the Company granted to Motorola the Convertible Promissory Note that was convertible, at the option of Motorola, into Shares or other securities of the Company upon the same terms as would be offered to other investors in the Company's next future equity financing in excess of $15 million. If no such Company financing occurred and either (i) the Company delivered a notice of prepayment of this $20 million tranche or (ii) this $20 million tranche would mature within thirty days, then Motorola, at its option, could convert the outstanding principal and interest under the Convertible Promissory Note into Shares at a rate of $4.29 per share, subject to customary anti-dilution protection provisions. This $20 million tranche could not be prepaid while there was outstanding any other loans under the Credit Agreement, as amended. The Convertible Promissory Note was canceled in exchange for receipt of shares of Series A-1 Preferred pursuant to the terms of the June 2002 Securities Purchase Agreement, as described below.

        As additional consideration for entering into the December 11, 2001 Amendment, the Company granted Motorola Warrant No. 11 to acquire 2,500,000 Shares, with an exercise price of $4.29 per share. Warrant No. 11 is currently exercisable and expires on December 10, 2006.

        On February 21, 2002, Motorola and the Company entered into the February 2002 Securities Purchase Agreement whereby Motorola purchased 6,912,442 shares of the Series A Preferred at a per share purchase price of $4.34, for a total purchase price of approximately $30 million. Each share of Series A Preferred is convertible into two shares of the Company's common stock; is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of Series A

9



Preferred; and is entitled to a liquidation preference of $10.85 in the event of insolvency or dissolution of the company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of Company's assets outside the ordinary course of business. Each holder of Series A Preferred may vote its shares on an as-converted basis. In addition, certain material actions require the consent of a majority of the holders of the Series A Preferred. Finally, a majority of the holders of the Series A Preferred were able to call for redemption of the Series A Preferred on or after February 19, 2007 at a per share redemption price of $5.21. On December 18, 2002 the Company amended the terms of the outstanding Series A Preferred as discussed below. As a result of the amendment the majority holders of the Series A Preferred may no longer call for redemption of the Series A Preferred and the events under which a Series A Preferred holder is entitled to a liquidation preference have been amended. In addition, the Company granted Motorola Warrant No. Series A 001 for 3,456,221 Shares with an exercise price of $2.17 per share and Warrant No. Series A 002 for 3,456,221 Shares with an exercise price of $2.60 per share. These warrants are currently exercisable and expire on February 19, 2007.

        Pursuant to the Commitment Letter, Motorola agreed to provide the Financing Facility to the Company. The Commitment Letter provided that Motorola had the option at the time of any drawdown thereunder by the Company of the Financing Facility to either treat such drawdown as (a) an increase in the aggregate principle amount of convertible secured debt owed by the Company to Motorola under the Credit Agreement as represented by the Convertible Promissory Note, or (b) as an additional preferred stock investment with terms (other than price) substantially identical to those contained in the February 2002 Securities Purchase Agreement. In either instance, the Company would grant Motorola warrant coverage consistent in amount with that given in connection with either the Convertible Promissory Note or the February 2002 Securities Purchase Agreement. The pricing of any preferred stock investment or of any of the March 2002 Warrants would be the lower of the average of the closing prices of the Company's Shares for either (a) the five days prior to March 29, 2002, or (ii) five days prior to the particular drawdown by the Company. The Company drew down (i) $13 million and (ii) $10 million, respectively, under the Financing Facility for shares of the Series A-1 Preferred pursuant to the terms of the June 2002 and September 2002 Securities Purchase Agreements, as described below. The Company drew down the remaining $12 million under the Financing Facility on December 18, 2002 for shares of Series A-2 Convertible Preferred Stock of the Company pursuant to the December 2002 Securities Purchase Agreement as described below. The Convertible Promissory Note was cancelled on June 25, 2002 as discussed below and therefore after June 25, 2002 Motorola no longer had the option to treat a drawdown under the Financing Facility as described in (a) above.

        Pursuant to the Letter of Certification, Motorola agreed that, within ten days of the execution of such letter, Motorola would execute and deliver to the Company a waiver pursuant to which it would, in its capacity as holder of the Company's Series A Preferred, agree through November 1, 2002: (i) to waive, its right of redemption under Section B(2) of the Certificate of Designation of the Company's Series A Preferred in the event of a change of control or sale of a material portion of the Company's assets and (ii) not to transfer the Series A Preferred unless the transferee agrees in writing to be bound by the foregoing waiver. Pursuant to the terms of the September 2002 Securities Purchase Agreement, as described below, this waiver was extended to April 1, 2003. Pursuant to the December 2002 Securities Purchase Agreement as described below, the amendment of the terms of the Series A Preferred on December 18, 2002, as also described below, supercedes this waiver. As a result this waiver is no longer in effect.

        In addition, Motorola agreed in the Letter of Certification that it would undertake that to the extent necessary for the Company to achieve compliance with all current Nasdaq National Market listing requirements (including, when applicable, the stockholders' equity requirement) by June 30, 2002 and for the remainder of fiscal year 2002, it would: (a) modify all or a portion of its Financing Facility

10



by amending the terms of the Financing Facility such that any drawdowns by the Company under the Financing Facility will be in exchange for the issuance of Series A Preferred subject to the waiver of the change of control redemption right described above; (b) if the modification to the Financing Facility contemplated by clause (a) is not sufficient for the Company to maintain compliance with the listing requirements, convert up to $6 million of the Company's existing indebtedness to Motorola to equity such that the converted indebtedness will be classified as equity on the Company's balance sheet on a going forward basis; and (c) if necessary to comply with the Nasdaq National Market's stockholders' equity requirement once it becomes mandatory in the fourth quarter of 2002, further amend the terms of the Series A Preferred such that it would be classified as equity on the Company's balance sheet on a going forward basis for purposes of the stockholders' equity listing requirement. The Letter of Certification also provided that the foregoing shall not limit the ability of Motorola and the Company to cause the Company to achieve and maintain compliance with all Nasdaq National Market listing requirements pursuant to reverse stock splits or other restructuring of Series A Preferred or indebtedness of the Company to Motorola in a manner so that such preferred stock or indebtedness would be classified as equity on the Company's balance sheet. Motorola has taken the necessary actions as agreed to in the Letter of Certification.

        As consideration for the Letter of Certification to NASD, the Company issued to Motorola the following warrants, exercisable five years from the date of the NASD letter all with an exercise price of $2.00 per share and expiring on April 22, 2012: (i) 100,000 warrants for the Letter of Certification and the overall contingent re-structuring; and (ii) 300,000 warrants for the waiver of the redemption in the event of a change of control relating to the $30 million Series A.

        On June 25, 2002, Motorola and the Company entered into the June 2002 Securities Purchase Agreement whereby Motorola purchased 277,311 shares of the June 2002 Series A-1 Preferred at a per share purchase price of $119.00, for a total purchase price of approximately $33 million. The total purchase price consisted of (i) the cancellation of the $20 million under the Convertible Promissory Note issued by the Company to Motorola in exchange for receipt of shares of June 2002 Series A-1 Preferred and (ii) cash in the amount of $13 million representing a drawdown on the Financing Facility. Each share of June 2002 Series A-1 Preferred is initially convertible into 100 shares of the Company's common stock and is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of June 2002 Series A-1 Preferred. Holders of Series A-1 Preferred may vote their shares together with holders of Common Stock on an as-converted to common stock basis, and certain material actions require the consent of holders of a majority of the Series A-1 Preferred. In addition each share of June 2002 Series A-1 Preferred is entitled to a liquidation preference of $297.50 per share in the event of insolvency or dissolution of the Company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of Company's assets outside the ordinary course of business. Motorola had waived its right to receive the liquidation preference in the event of a change of control or sale of a material portion of the Company's assets if such event occurred prior to April 1, 2003. Pursuant to the December 2002 Securities Purchase Agreement as described below, the amendment of the terms of the Series A-1 Preferred on December 18, 2002, as also described below, supercedes this waiver. As a result this waiver is no longer in effect. Lastly, holders of a majority of the Series A-1 Preferred were able to require the Company to redeem the Series A-1 Preferred on or after June 25, 2007. The per share redemption price of June 2002 Series A-1 Preferred was $142.80. On December 18, 2002 the Company amended the terms of the outstanding Series A-1 Preferred as discussed below. As a result of the amendment the majority holders of the Series A-1 Preferred may no longer call for redemption of the Series A-1 Preferred and the events under which a Series A-1 holder is entitled to a liquidation preference have been amended. On June 25, 2002 in connection with the issuance of the June 2002 Series A-1 Preferred, the Company granted Motorola: (i) Warrant A-1 001 to purchase 6,008,403 shares of the Company's common stock which is currently exercisable with an exercise price of $1.19 per share and expiring on June 24, 2007 and (ii) a Warrant A-1 002 to purchase 330,000 shares of the Company's

11



common stock which is exercisable after June 25, 2007 with an exercise price of $2.00 per share expiring on June 24, 2012.

        On September 26, 2002, Motorola and the Company entered into the September 2002 Securities Purchase Agreement whereby Motorola purchased 236,559 shares of the September 2002 Series A-1 Preferred at a per share purchase price of $93.00, for a total purchase price of approximately $22 million. The total purchase price consisted of (i) the cancellation of $12 million under the Credit Agreement, dated as of May 16, 2001 between the Company and Motorola, as amended, and (ii) cash in the amount of $10 million representing a drawdown on the Financing Facility. Each share of September 2002 Series A-1 Preferred is initially convertible into 100 shares of the Company's common stock and is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of September 2002 Series A-1 Preferred. Holders of Series A-1 Preferred may vote their shares together with holders of Common Stock on an as-converted to common stock basis, and certain material actions require the consent of holders of a majority of Series A-1 Preferred. Each share of September 2002 Series A-1 is entitled to a liquidation preference of $232.50 per share in the event of insolvency or dissolution of the Company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of the Company's assets outside the ordinary course of business. Motorola had waived its right to receive the liquidation preference in the event of a change of control or sale of a material portion of the Company's assets if such event occurred prior to April 1, 2003. Pursuant to the December 2002 Securities Purchase Agreement as described below, the amendment of the terms of the Series A-1 Preferred on December 18, 2002, as also described below, supercedes this waiver. As a result this waiver is no longer in effect. Lastly, holders of a majority of the Series A-1 Preferred were able to require the Company to redeem the Series A-1 Preferred on or after June 25, 2007. The per share redemption price of the September 2002 Series A-1 Preferred was $111.60. On December 18, 2002 the Company amended the terms of the outstanding Series A-1 Preferred as discussed below. As a result of the amendment the majority holders of the Series A-1 Preferred may no longer call for redemption of the Series A-1 Preferred and the events under which a Series A-1 holder is entitled to a liquidation preference have been amended. On September 26, 2002 in connection with the issuance of the September 2002 Series A-1 Preferred, the Company granted Motorola (i) Warrant No. A-1 003 for 220,000 shares with an exercise price of $2.00 per share which is exercisable after September 26, 2007 and (ii) Warrant No. A-1 004 for 5,913,978 shares with an exercise price of $0.93 per share, which is currently exercisable. The warrants expire on September 25, 2012 and September 25, 2007, respectively.

        On October 22, 2002, pursuant to the October 22, 2002 Amendment to the Credit Agreement, Motorola agreed to extend the maturity date of the Credit Agreement from May 16, 2003 to May 16, 2006.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of Issuer.

        Item 6 is amended and restated to read as follows:

        General Instrument entered into the following agreements with respect to its ownership of the 64,103,724 Shares that are now beneficially owned by Motorola. The following summary of certain provisions of these agreements is qualified in its entirety by reference to these agreements themselves, which are filed as exhibits hereto and hereby incorporated by reference.

        Corporate and Intercompany Agreement.    General Instrument and the Company have entered into the Corporate and Intercompany Agreement, dated as of November 15, 1999, (the "Corporate and Intercompany Agreement") under which, among other things, the Company has granted General Instrument and its affiliates a continuing option to purchase additional Shares or shares of non-voting capital stock of the Company. If the Company issues any additional equity securities after its initial public offering, General Instrument and its affiliates may exercise this option to purchase: (i) Shares to the extent necessary for them to maintain their then-existing percentage of the total voting power; and (ii) shares of non-voting capital to the extent necessary to own 80% of any class of non-voting capital stock which may be outstanding. The purchase price of the Shares will be the market price of the

14



common stock. The purchase price of non-voting capital stock will be the price at which third parties may purchase this stock. The stock option expires if General Instrument and its affiliates beneficially own less than 30% of the outstanding Shares.

        The Corporate and Intercompany Agreement also provides that, immediately upon the termination of the Voting Trust, the Company and its board of directors will take all actions necessary to appoint on the date of termination any number of additional directors nominated by General Instrument. As indicated in Item 4 above, upon the Merger, the Company's board appointed four individuals as Company directors at Motorola's request.

        Registration Rights Agreement dated November 15, 1999.    General Instrument, Spencer Trask Investors LLC ("Spencer Trask") and the Company entered into a registration rights agreement, dated as of November 15, 1999 (the "1999 Registration Rights Agreement"). Under the 1999 Registration Rights Agreement, the Company granted to these stockholders and their affiliates the right to request that the Company use its best efforts to register their Shares under federal and state securities laws so that they may sell or dispose of their Shares in accordance with these laws. So long as General Instrument and its affiliates own 30% of the Company's outstanding common stock, they will not be limited in the number of times they may make that request. After their ownership declines below that level, they will be able to cause the Company to effect up to four demand registration of their Shares. Under customary "piggy-back" registration rights, General Instrument and its affiliates will also be entitled to include their 64,103,724 Shares in all registrations of common stock that the Company makes, either for a sale by the Company or any of its stockholders, subject to customary exceptions. The Company will pay for all out-of-pocket expenses relating to these registrations and indemnify General Instrument and its affiliates against liabilities under securities laws. General Instrument and its affiliates may generally assign these registration rights to transferees of their 64,103,724 Shares.

        Motorola has entered into the following agreements with respect to its ownership of the Shares. The following summary of certain provisions of these agreements is qualified in its entirety by reference to these agreements themselves, which are filed as exhibits hereto and hereby incorporated by reference

Under the terms of the December 11, 2001 Amendment, the Company granted to Motorola a Convertible Promissory Note that was convertible, at the option of Motorola, into Shares or other securities of the Company upon the same terms as would be offered to other investors in the Company's next future equity financing in excess of $15 million. If no such Company financing occurred and either (i) the Company delivered a notice of prepayment of this $20 million tranche or (ii) this $20 million tranche would mature within thirty days, then Motorola, at its option, could convert the outstanding principal and interest under the Convertible Promissory Note into Shares at a rate of $4.29 per share, subject to customary anti-dilution protection provisions. This $20 million tranche could not be prepaid while there was outstanding any other loans under the Credit Agreement, as amended. The Convertible Promissory Note was cancelled in exchange for receipt of shares of Series A-1 Preferred pursuant to the terms of the June 2002 Securities Purchase Agreement, as described below.

        Guarantee and Environmental Indemnity Agreements.    On October 24, 2001, Motorola entered into: i) a Guarantee pursuant to which Motorola will guarantee the Company's $20 million mortgage loan obligation to a third party; and ii) an Environmental Indemnity Agreement in favor of the third party relating to real estate security. In exchange for Motorola entering into the Guarantee and Environmental Indemnity Agreements, the Company granted Motorola warrants for an additional 400,000 shares of the Company's common stock with an exercise price of $3.82 per share.

Finally, a majority of the holders of the Series A Preferred were able to call for redemption of the Series A Preferred on or after February 19, 2007 at a per share redemption price of $5.21. On December 18, 2002 the Company amended the terms of the outstanding Series A Preferred as discussed below. As a result of the amendment the majority holders of the Series A Preferred may no longer call for redemption of the Series A Preferred and the events under which a Series A Preferred holder is entitled to a liquidation preference have been amended. As additional consideration for Motorola entering into the February 2002 Securities Purchase Agreement discussed above, the Company granted Motorola Warrant No. Series A 001 for 3,456,221 Shares with an exercise price of $2.17 per share. Warrant No. Series A 001 is currently exercisable and expires on February 19, 2007.

Registration Rights Agreement was amended to provide that such agreement would cover any Shares issued pursuant to the Warrant No. 10. In connection with the December 11, 2001 Credit Agreement Amendment, Convertible Promissory Note and Warrant No. 11 discussed above, the 2001 Registration Rights Agreement was again amended to provide that any Shares issued pursuant to Warrant No. 11 or pursuant to the Convertible Promissory Note would be covered by such agreement. At the same time, the 2001 Registration Rights Agreement was also amended to increase the number of demand registration rights from four to five. In connection with the October 22, 2002 Credit Agreement Amendment and Warrant No. 12 discussed above, the 2001 Registration Rights Agreement was again amended to provide that any Shares issued pursuant to Warrant No. 12 would be covered by such agreement.

        Registration Rights Agreement dated February 20, 2002.    In connection with the February 2002 Securities Purchase Agreement, Warrant No. Series A 001 and Warrant No. Series A 002 discussed above, the Company also entered into a Registration Rights Agreement ("February 2002 Registration Rights Agreement") pursuant to which the Company granted Motorola both demand registration rights (for up to four registrations) and piggyback registration rights related to Shares obtained in connection with the Series A Preferred stock or Warrants No. Series A 001 and A 002. The Company further agreed to use its best efforts to ensure that the conditions to the availability of Rule 144 set forth in paragraph (c) thereof shall be satisfied, and to use its reasonable efforts to cause all conditions to the availability of Form S-3 to be met as soon as practicable after the date of the February 2002 Registration Rights Agreement. The February 2002 Registration Rights Agreement was amended as of April 22, 2002 to make it clear that the warrants issued as consideration for the Letter of Certification to NASD, as described below, were entitled to the benefits of the February 2002 Registration Rights Agreement.

        Commitment Letter.    Pursuant to the Commitment Letter dated March 29, 2002 between Motorola and the Company, Motorola agreed to provide the Financing Facility to the Company. The Commitment Letter provided that Motorola had the option at the time of any drawdown thereunder by the Company of the Financing Facility to either treat such drawdown as (a) an increase in the aggregate principle amount of convertible secured debt owed by the Company to Motorola under the Credit Agreement as represented by the Convertible Promissory Note, or (b) as an additional preferred stock investment with terms (other than price) substantially identical to those contained in the Securities Purchase Agreement. In either instance, the Company would grant Motorola warrant coverage consistent in amount with that given in connection with either the Convertible Promissory Note or the Securities Purchase Agreement. The pricing of any preferred stock investment or of any of the March 2002 Warrants would be the lower of the average of the closing prices of the Company's Shares for either (a) the five days prior to March 29, 2002, or (ii) five days prior to the particular drawdown by the Company. The Company drew down (i) $13 million and (ii) $10 million, respectively, under the Financing Facility for shares of the Series A-1 Preferred pursuant to the terms of the June 2002 and September 2002 Securities Purchase Agreements, respectively, as described below. The Company drew down the remaining $12 million under the Financing Facility on December 18, 2002 for shares of Series A-2 Convertible Preferred Stock of the Company pursuant to the terms of a Securities Purchase Agreement between the Company and Motorola dated December 18, 2002 as described below. The Convertible Promissory Note was cancelled on June 25, 2002 as discussed below and therefore after June 25, 2002 Motorola no longer had the option to treat a drawdown under the Financing Facility as described in (a) above.

        Letter of Certification.    Pursuant to the Letter of Certification, Motorola agreed that, within ten days of the execution of such letter, Motorola would execute and deliver to the Company a waiver pursuant to which it would, in its capacity as holder of the Company's Series A Preferred, agree through November 1, 2002: (i) to waive its right of redemption under Section B(2) of the Certificate of Designation of the Company's Series A Preferred in the event of a change of control or sale of a

17



material portion of the Company's assets and (ii) not to transfer the Series A Preferred unless the transferee agrees in writing to be bound by the foregoing waiver. Pursuant to the terms of the September 2002 Securities Purchase Agreement, as described below, this waiver has been extended to April 1, 2003. Pursuant to the terms of the December 2002 Securities Purchase Agreement as described below, the amendment of the terms of the Series A Preferred on December 18, 2002, as also described below, supercedes this waiver. As a result this waiver is no longer in effect.

        In addition, Motorola agreed in the Letter of Certification that it would undertake that to the extent necessary for the Company to achieve compliance with all current Nasdaq National Market listing requirements (including, when applicable, the stockholders' equity requirement) by June 30, 2002 and for the remainder of fiscal year 2002, it would: (a) modify all or a portion of its Financing Facility by amending the terms of the Financing Facility such that any drawdowns by the Company under the Financing Facility will be in exchange for the issuance of Series A Preferred subject to the waiver of the change of control redemption right described above; (b) if the modification to the Financing Facility contemplated by clause (a) is not sufficient for the Company to maintain compliance with the listing requirements, convert up to $6 million of the Company's existing indebtedness to Motorola to equity such that the converted indebtedness will be classified as equity on the Company's balance sheet on a going forward basis; and (c) if necessary to comply with the Nasdaq National Market's stockholders' equity requirement once it becomes mandatory in the fourth quarter of 2002, further amend the terms of the Series A Preferred such that it would be classified as equity on the Company's balance sheet on a going forward basis for purposes of the stockholders' equity listing requirement. The Letter of Certification also provided that the foregoing shall not limit the ability of Motorola and the Company to cause the Company to achieve and maintain compliance with all Nasdaq National Market listing requirements pursuant to reverse stock splits or other restructuring of Series A Preferred or indebtedness of the Company to Motorola in a manner so that such preferred stock or indebtedness would be classified as equity on the Company's balance sheet. Motorola has taken the necessary actions as agreed to in the Letter of Certification.

        As consideration for the Letter of Certification to NASD, the Company issued to Motorola the following warrants, exercisable five years from the date of the NASD letter all with an exercise price of $2.00 per share and expiring on April 22, 2012: (i) 100,000 warrants for the Letter of Certification and the overall contingent re-structuring; and (ii) 300,000 warrants for the waiver of the redemption in the event of a change of control relating to the $30 million Series A, collectively (the "A 003 Warrant").

        Securities Purchase Agreement dated June 25, 2002.    On June 25, 2002, Motorola and the Company entered into the June 2002 Securities Purchase Agreement whereby Motorola purchased 277,311 shares of the June 2002 Series A-1 Preferred at a per share purchase price of $119.00, for a total purchase price of approximately $33 million. The total purchase price consisted of (i) the cancellation of the $20 million under the Convertible Promissory Note issued by the Company to Motorola in exchange for shares of June 2002 Series A-1 Preferred and (ii) cash in the amount of $13 million representing a drawdown on the Financing Facility. Each share of June 2002 Series A-1 Preferred is initially convertible into 100 shares of the Company's common stock-and is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of June 2002 Series A-1 Preferred. Holders of Series A-1 Preferred may vote their shares together with holders of Common Stock on an as-converted to common stock basis, and certain material actions require the consent of holders of a majority of the Series A-1 Preferred. In addition each share of June 2002 Series A-1 Preferred is entitled to a liquidation preference of $297.50 per share in the event of insolvency or dissolution of the Company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of Company's assets outside the ordinary course of business. Motorola had waived its right to receive the liquidation preference in the event of a change of control or sale of a material portion of the Company's assets if such event occurred prior to April 1, 2003. Pursuant to the December 2002 Securities Purchase Agreement as described below, the amendment of

18



the terms of the Series A-1 Preferred on December 18, 2002, as also described below, supercedes this waiver. As a result this waiver is no longer in effect. Lastly, holders of a majority of the Series A-1 Preferred were able to require the Company to redeem the Series A-1 Preferred on or after June 25, 2007. The per share redemption price of the June 2002 Series A-1 Preferred was $142.80. On December 18, 2002 the Company amended the terms of the outstanding Series A-1 Preferred as discussed below. As a result of the amendment the majority holders of the Series A-1 Preferred may no longer call for redemption of the Series A-1 Preferred and the events under which a Series A-1 holder is entitled to a liquidation preference have been amended. On June 25, 2002 in connection with the issuance of the June 2002 Series A-1 Preferred, the Company granted Motorola: (i) a warrant to purchase 6,008,403 shares of the Company's common stock which is currently exercisable with an exercise price of $1.19 per share and expiring on June 24, 2007 and (ii) a warrant to purchase 330,000 shares of the Company's common stock which is exercisable after June 25, 2007 with an exercise price of $2.00 per share expiring on June 24, 2012.

        Registration Rights Agreement dated June 25, 2002 as amended.    In connection with the Securities Purchase Agreement dated June 25, 2002, Warrant No. A-1 001 and Warrant No. A-1 002 discussed above, the Company also entered into a Registration Rights Agreement (the "June 2002 Registration Rights Agreement") pursuant to which the Company granted Motorola both demand registration rights (for up to four registrations) and piggyback registration rights related to Shares obtained in connection with the Series A-1 Preferred stock or Warrants Nos. A 001 and A 002. The Company further agreed to use its best efforts to ensure that the conditions to the availability of Rule 144 set forth in paragraph (c) thereof shall be satisfied, and to use its reasonable efforts to cause all conditions to the availability of Form S-3 to be met as soon as practicable after the date of the June 2002 Registration Rights Agreement. In connection with the September 2002 Securities Purchase Agreement, the June 2002 Registration Rights Agreement was amended to provide that any Shares issued pursuant to September 2002 Securities Purchase Agreement or pursuant to Warrant No. A-1 003 and Warrant No. A-1 004 would be covered by such agreement. In connection with the December 2002 Securities Purchase Agreement, the June 2002 Registration Rights Agreement was amended to provide that any Shares issued pursuant to December 2002 Securities Purchase Agreement or pursuant to Warrant No. A-2 001 and Warrant No. A-2 002 would be covered by such agreement.

        Securities Purchase Agreement dated September 26, 2002.    On September 26, 2002, Motorola and the Company entered into the September 2002 Securities Purchase Agreement whereby Motorola purchased 236,559 shares of the September 2002 Series A-1 Preferred at a per share purchase price of $93.00, for a total purchase price of approximately $22 million. The total purchase price consisted of (i) the cancellation of $12 million under the Credit Agreement, dated as of May 16, 2001 between the Company and Motorola, as amended, and (ii) cash in the amount of $10 million representing a drawdown on the Financing Facility. Each share of September 2002 Series A-1 Preferred is initially convertible into 100 shares of the Company's common stock and is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of September 2002 Series A-1 Preferred. Holders of Series A-1 Preferred may vote their shares together with holders of Common Stock on an as-converted to common stock basis, and certain material actions require the consent of holders of a majority of Series A-1 Preferred. Each share of the September 2002 Series A-1 is entitled to a liquidation preference of $232.50 per share in the event of insolvency or dissolution of the Company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of the Company's assets outside the ordinary course of business. Motorola had waived its right to receive the liquidation preference in the event of a change of control or sale of a material portion of the Company's assets if such event occurred prior to April 1, 2003. Pursuant to the terms of a Securities Purchase Agreement between the Company and Motorola dated December 18, 2002 as described below, the amendment of the terms of the Series A-1 Preferred on December 18, 2002, as described below, supercedes this waiver. As a result this waiver is no longer in effect. Lastly, holders of a majority of Series A-1 Preferred were able to require the Company to

19



redeem the Series A-1 Preferred on or after June 25, 2007. The per share redemption price of the September 2002 Series A-1 Preferred was $111.60. On December 18, 2002 the Company amended the terms of the outstanding Series A-1 Preferred as discussed below. As a result of the amendment the majority holders of the Series A-1 Preferred may no longer call for redemption of the Series A-1 Preferred and the events under which a Series A-1 holder is entitled to a liquidation preference have been amended. On September 26, 2002 in connection with the issuance of the September 2002 Series A-1 Preferred, the Company granted Motorola (i) a warrant to purchase 220,000 shares of the Company's common stock which is exercisable after September 26, 2007 with an exercise price of $2.00 per share and (ii) a warrant to purchase 5,913,978 shares of the Company's common stock which is currently exercisable with an exercise price of $0.93 per share. The warrants expire on September 25, 2012 and September 25, 2007, respectively.

        On December 18, 2002, Motorola and the Company entered into the December 2002 Securities Purchase Agreement whereby Motorola purchased shares of the Series A-2 Preferred Stock. Pursuant to the terms of the December 2002 Securities Purchase Agreement, Motorola purchased 26,506 shares of the December 2002 Series A-2 Preferred at a per share purchase price of $830.00, for a total purchase price of approximately $22 million. The total purchase price consisted of (i) the cancellation of $10 million under the Credit Agreement, dated as of May 16, 2001 between the Company and Motorola, as amended, and (ii) cash in the amount of $12 million representing a drawdown on the Financing Facility. Each share of December 2002 Series A-2 Preferred is initially convertible into 1000 shares of the Company's common stock; is entitled to cumulative dividends at an annual rate of 7.5%, payable in cash or additional shares of December 2002 Series A-2 Preferred; and is entitled to a liquidation preference of $2,075 per share in the event of insolvency or dissolution of the Company, in the event of certain change in control, merger or consolidation events and in the event of sales or transfers of a material portion of the Company's assets outside the ordinary course of business. Holders of Series A-2 Preferred may vote their shares together with holders of Common Stock and Series A-1 Preferred on an as-converted to common stock basis, and certain material actions require the consent of holders of a majority of Series A-1 and A-2 Preferred. In connection with the issuance of the December 2002 Series A-2 Preferred, the Company granted Motorola (i) a warrant to purchase 220,000 shares of the Company's common stock which is exercisable after December 18, 2007 with an exercise price of $2.00 per share ("Warrant No. A-2 001") and (ii) a warrant to purchase 7,951,807 shares of the Company's common stock which is currently exercisable with an exercise price of $0.83 per share ("Warrant No. A-2 002").
