or all of the securities of the Issuer beneficially owned by
them.  In addition, MedCap may receive stock dividends on the

     of Common Stock.  MedCap also owns warrants giving it the
     right to acquire (i) 6,000 shares of Series B-1 Preferred
     Stock for $60 per share (6,000 shares of Series B-1
     Preferred Stock, in turn, would currently be convertible
     into 600,000 shares of Common Stock) and (ii) 100,111 shares
     of Series C Preferred Stock for $60 per share (100,111
     shares of Series C Preferred Stock, in turn, would currently
     be convertible into 10,011,100 shares of Common Stock).

CUSIP No. 225235209                SCHEDULE 13D                Page 8 of 31

     MMR as general partner and investment manager of MedCap and
     Toney as the sole managing member of MMR may be deemed to
     beneficially own the shares owned by MedCap in that they may
     be deemed to have the power to direct the voting or
     disposition of the shares.  Neither the filing of this
     Schedule 13D nor any of its contents shall be deemed to
     constitute an admission that either MMR or Toney is, for any
     other purpose, the beneficial owner of any such securities
     to which this Schedule relates, and MMR and Toney disclaim
     beneficial ownership as to the Common Stock except to the
     extent of their respective pecuniary interests therein.
     Based on the number of shares outstanding reported in the
     Issuer's most recent annual report on Form 10-KSB and shares
     reported in filings with the SEC as being issued to various
     parties, the percentage of Common Stock beneficially owned
     by MedCap, MMR and Toney for the purposes of this Schedule
     13D is 64.9%.
     
(b)  Reference is made hereby to Items 7 to 10 of pages 3, 4 and
     5 of this Schedule, which Items are incorporated herein by
     reference.
     
(c)  On May 2, 2005, MedCap exercised a warrant that it held to
     acquire from the Issuer 22,187 shares of Series C Preferred
     Stock (currently convertible into 2,218,700 shares of Common
     Stock) for a total consideration of $1,331,220 (the Series C
     Preferred Stock acquired upon the exercise of the warrants
     are referred to as the "Warrant Shares").  The consideration
     for the Warrant Shares consisted of $1,331,220 in cash.
     Under the terms of the warrant, the exercise price was $60
     for each share of Series C Preferred Stock.
     
     As part of a March 29, 2005 financing, the Issuer entered
     into a letter agreement with MedCap (the "Letter Agreement")
     pursuant to which the Issuer agreed to register for resale
     (i) all of the shares of Common Stock and the Common Stock
     that can be acquired upon the conversion of the Series C
     Preferred Stock that are held by MedCap and (ii) shares of
     Common Stock underlying all of the warrants that MedCap
     holds to acquire the Issuer's preferred stock; provided
     that, the Issuer is not required to register for resale
     Common Stock underlying the warrants unless such shares can
     be registered at the time that the shares of Common Stock
     listed in item (i) are registered for resale.  Under a
     previous registration rights agreement executed by the
     Issuer, which in part is amended by the Letter Agreement,
     MedCap and certain other investors have a right to require
     the Issuer to register additional shares of Common Stock
     that may become outstanding following the exercise of
     certain warrants to acquire preferred stock and the
     conversion of such preferred stock into Common Stock;
     provided that, such shares of Common Stock have not already
     been registered for resale by the Issuer.

CUSIP No. 225235209                SCHEDULE 13D                Page 9 of 31

     In connection with the exercise of the warrant, the Issuer
     and MedCap entered into an Amendment to Letter Agreement
     (the "Letter Agreement Amendment") which amended the date by
     which the Issuer is required to register for resale the
     securities held by MedCap and provided that the Common Stock
     into which the newly acquired Series C Preferred Stock can
     be converted also be registered for resale.
     
     Series C Preferred Stock is currently convertible at the
     option of its holder into 100 shares of Common Stock per
     share of Series C Preferred Stock.  MedCap currently has
     outstanding warrants permitting it to acquire 100,111 shares
     of Series C Preferred Stock for $60 per share and the
     warrants for Series C Preferred Stock that MedCap holds
     would currently be indirectly convertible into 10,011,100
     shares of Common Stock
     
     Under the terms of the warrants for the Series C Preferred
     Stock, the Issuer was required to make a distribution on the
     22,187 shares of Series C Preferred Stock that were acquired
     by MedCap upon the exercise of the warrant at the same rate
     as the dividends previously paid on the outstanding shares
     of Series C Preferred Stock.  As a result, upon the exercise
     of the warrant on May 2, 2005, MedCap received 110,935
     shares of Common Stock (for no additional consideration) in
     addition to the 22,187 shares of Series C Preferred Stock.
     
(d)  Not applicable.
     
(e)  Not applicable.
     
Item 6.     Contracts, Arrangements, Understandings or
            Relationships with Respect to Securities of the
            Issuer
            
        MedCap is a party to an Amended and Restated Registration
Rights Agreement entitling it to registration rights with respect
to Common Stock issuable upon conversion of its shares of Series
A Preferred Stock, Series B-1 Preferred Stock and Series C
Preferred Stock, including any Series B-1 Preferred or Series C
Preferred issued upon exercise of the Warrants.

CUSIP No. 225235209                SCHEDULE 13D                Page 10 of 31

        MedCap and the Issuer are also parties to the Letter
Agreement, as amended by the Letter Agreement Amendment, which
amends in part the Amended and Restated Registration Rights
Agreement.  Under the Letter Agreement, the Issuer agrees to
register for resale (i) all of the shares of Common Stock and the
Common Stock that can be acquired upon the conversion of the
Series C Preferred Stock that are held by MedCap and (ii) shares
of Common Stock underlying all of the warrants that MedCap holds
to acquire the Issuer's preferred stock; provided that, the
Issuer is not required to register for resale Common Stock
underlying the warrants unless such shares can be registered at
the time that the shares of Common Stock listed in item (i) are
registered for resale.

        This Amendment to Letter Agreement (this "Amendment") is
made effective as of May 2, 2005 by and between Crdentia Corp., a
Delaware corporation (the "Company"), and MedCap Partners L.P.
("MedCap").

                            RECITALS
                                
        A.  In connection with MedCap's exercise of warrants to
purchase 108,334 shares of the Company's Series C Preferred
Stock, on March 29, 2005, the Company and MedCap entered into a
letter agreement (the "Letter Agreement").

        B.  MedCap desires to exercise additional warrants to
purchase 22,187 shares of the Company's Series C Preferred Stock
(the "Additional Financing").

        C.  In connection with the Additional Financing, the
Company and MedCap desire to amend certain terms of the Letter
Agreement.

        In consideration of the foregoing and the promises and
covenants contained herein and other good and valuable
consideration the receipt of which is hereby acknowledged, the
parties hereto agree as follows.  Any capitalized terms not
otherwise defined herein shall have the meanings given such terms
in the Letter Agreement:

    1.  Amendment to First Paragraph of the Letter Agreement.
     
     The first paragraph of the Letter Agreement shall be amended
and restated to read as follows:

             "This letter agreement (this "Letter Agreement")
     reflects certain understandings by and between Crdentia
     Corp. (the "Company") and MedCap Partners L.P. ("MedCap") in
     connection with (i) MedCap's exercise of warrants to
     purchase 108,334 shares of the Company's Series C Preferred
     Stock on March 29, 2005 and (ii) MedCap's exercise of
     warrants to purchase 22,187 shares of the Company's Series C
     Preferred Stock on May 2, 2005 ((i) and (ii) collectively
     referred to as the "Financing").
     
    2.  Amendment to Section 2(a) of the Letter Agreement.
        
        The first sentence of Section 2(a) of the Letter
Agreement shall be amended and restated to read as follows:

CUSIP No. 225235209                SCHEDULE 13D                Page 16 of 31

            "The Company hereby acknowledges and agrees that it
will, by the earlier of (i) one (1) business day following the
filing of its Quarterly Report on Form 10-QSB for the quarter
ended March 31, 2005 with the Securities and Exchange Commission
(the "SEC"), or (ii) the date that is two (2) calendar weeks from
the May 2, 2005 closing of the Financing (the "Closing"), file a
registration statement with the SEC under the Securities Act of
1933, as amended, covering the resale of all MedCap Shares (as
defined below), and use its reasonable efforts to have such
registration statement declared effective by the SEC within
ninety (90) days of the Closing."

        3.  Distribution of Proceeds.  The Company acknowledges
and agrees that the proceeds of the Additional Financing shall be
distributed as set forth on Schedule A attached hereto.

        4.  Representation of the Company.  The Company
represents that it has timely filed each statement, report and
other filing required to be filed with the Securities and
Exchange Commission by the Company between March 31, 2005 and the
date hereof (the "Company SEC Documents").  As of their
respective filing dates, the Company SEC Documents complied in
all material respects with the requirements of the Securities Act
of 1933, as amended, and the Securities Exchange Act of 1934, as
amended, and none of the Company SEC Documents contained any
untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make
the statements made therein, in light of the circumstances in
which they were made, not misleading, except to the extent
corrected by a subsequently filed Company SEC Document prior to
the date hereof.

        5.  Effect of Amendment.  Except as expressly amended,
restated or consented to in this Amendment, the Letter Agreement
shall continue in full force and effect.  In the event of any
conflict between the terms of this Amendment and the Letter
Agreement, the terms of this Amendment shall govern and control.

        6.  Attorney Fees.  The Company acknowledges and agrees
that it will pay reasonable attorney's fees and expenses incurred
by MedCap in connection with the Additional Financing, including
any such reasonable fees in connection with MedCap's filing of a
Schedule 13D related to the Additional Financing.

        7.  Governing Law.  This Amendment shall be governed by
and construed under the laws of the State of Delaware as applied
to agreements among Delaware residents entered into and to be
performed entirely within Delaware.

        8.  Counterparts.  This Amendment may be executed in any
number of counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the
same instrument.

        9.  Severability.  If one or more provisions of this
Amendment are held to be unenforceable under applicable law, such
provision shall be excluded from this Amendment and the balance
of the Amendment shall be interpreted as if such provision were
so excluded and shall be enforceable in accordance with its
terms.

        10. Entire Agreement.  This Amendment, together with the
Letter Agreement and the agreements executed pursuant hereto and
thereto, constitutes the full and entire understanding and
agreement between the parties with regard to the subjects hereof
and thereof.

     IN WITNESS WHEREOF, the parties hereto have executed this
Amendment as of the date first above written.

                               of

        This certifies that, for value received, MedCap Partners
L.P., together with its successors and assigns (the "Holder") is
entitled to subscribe for and purchase, on the terms hereof,
shares of Series C Preferred Stock (the "Stock") of Crdentia
Corp., a Delaware corporation (the "Company"), which is
convertible into shares of Common Stock of the Company (the
"Common Stock"), subject to adjustment as provided herein.

        This Warrant is subject to the following terms and
conditions:

        1.  Exercise of Warrant.  The terms and conditions upon
which this Warrant may be exercised, and the Stock covered hereby
may be purchased, are as follows:

          1.1   Term.  Subject to the terms hereof, this Warrant
may be exercised at any time after the date hereof, or from time
to time, in whole or in part; provided, however, that in no event
may this Warrant be exercised (the "Exercise Date") later than
5:00 p.m. (Pacific Time) on the earlier of (a) the close of
business on October 18, 2009 or (b) the closing of a Corporate
Transaction (as defined below) (the "Exercise Period"); provided
that at least twenty (20) days prior to the occurrence of the
closing of a Corporate Transaction, the Company shall have sent
to the Holder notice of such event.

CUSIP No. 225235209                SCHEDULE 13D                Page 20 of 31

          For purposes hereof, the term "Corporate Transaction"
shall mean (a) the sale, conveyance or disposal of all or
substantially all of the Company's property or business; (b) the
Company's merger into or consolidation with any other corporation
(other than a merger effected exclusively for the purpose of
changing the domicile of the Company or a merger in which the
owners of the voting stock of the Company prior to the merger own
at least 50% of the voting interests in the surviving entity) or
any other transaction or series of transactions, in which more
than fifty percent (50%) of the voting power of the Company is
disposed of (other than a sale by the Company of shares of its
capital stock in an equity financing); or (c) the closing of an
underwritten public offering of the Company's Common Stock
pursuant to a registration statement under the Securities Act of
1933, as amended (the "Securities Act"), with aggregate net
proceeds to the Company in excess of twenty-five million dollars
($25,000,000).

          1.2   Number of Shares.  This Warrant may be exercised
for 799 shares of Stock, subject to adjustment as provided
herein.

          1.3   Exercise Price.  The per share exercise price for
the shares of Stock to be issued upon exercise of this Warrant
shall be $60.00, subject to adjustment as provided herein (such
price as adjusted from time to time as provided herein is called
the "Exercise Price").

          1.4   Method of Exercise.  The exercise of the purchase
rights evidenced by this Warrant shall be effected by (a) the
surrender of the Warrant, together with a duly executed copy of
the form of a subscription attached hereto as Schedule 1, to the
Company at its principal offices and (b) except as set forth in
Section 1.5, the delivery of the aggregate Exercise Price by
check or bank draft payable to the Company's order or by wire
transfer to the Company's account for the number of shares for
which the purchase rights hereunder are being exercised or any
other form of consideration approved by the Company's Board of
Directors (the "Board").  Each exercise of this Warrant shall be
deemed to have been effected immediately prior to the close of
business on the day on which this Warrant shall have been
surrendered to the Company as provided herein or at such later
date as may be specified in the executed form of subscription,
and at such time the person or persons in whose name or names any
certificate or certificates for shares of Stock shall be issuable
upon such exercise as provided herein shall be deemed to have
become the holder or holders of record thereof.

CUSIP No. 225235209                SCHEDULE 13D                Page 21 of 31

          1.5   Net Issuance.

              (a)  Right to Convert.  In addition to and without
limiting the rights of the Holder under the terms of this
Warrant, the Holder shall have the right to convert this Warrant
or any portion thereof (the "Conversion Right") into shares of
Stock as provided in this Section 1.5 at any time or from time to
time during the Exercise Period.  Upon exercise of the Conversion
Right with respect to a particular number of shares subject to
the Warrant (the "Converted Warrant Shares"), the Company shall
deliver to the Holder (without payment by the Holder of any
exercise price or any cash or other consideration) that number of
shares of fully paid and nonassessable Stock computed using the
following formula:

                    X =  Y (A - B)
                            A

          Where     X =  the number of shares of Stock to be
                         delivered to the Holder

                    Y =  the number of Converted Warrant Shares

                    A =  the fair market value of the total
                         number of shares of Common Stock into
                         which one share of Stock can be
                         converted on the Conversion Date (as
                         defined below)

                    B =  the Exercise Price (as adjusted to the
                         Conversion Date)

        The Conversion Right may only be exercised with respect
to a whole number of shares subject to the Warrant.  No
fractional shares shall be issuable upon exercise of the
Conversion Right, and if the number of shares to be issued
determined in accordance with the foregoing formula is other than
a whole number, the Company shall pay to the Holder an amount in
cash equal to the fair market value of the resulting fractional
share on the Conversion Date (as defined below).  Shares issued
pursuant to the Conversion Right shall be treated as if they were
issued upon the exercise of the Warrant.

CUSIP No. 225235209                SCHEDULE 13D                Page 22 of 31

              (b)  Method of Exercise.  The Conversion Right may
be exercised by the Holder by the surrender of the Warrant at the
principal office of the Company together with a notice in the
form attached hereto as Schedule 2 specifying that the Holder
thereby intends to exercise the Conversion Right and indicating
the total number of shares under the Warrant that the Holder is
exercising through the Conversion Right.  Such conversion shall
be effective upon receipt by the Company of the Warrant together
with the aforesaid written statement, or on such later date as is
specified therein (the "Conversion Date").  Certificates for the
shares issuable upon exercise of the Conversion Right and, if
applicable, a new warrant evidencing the balance of the shares
remaining subject to the Warrant, shall be issued as of the
Conversion Date and shall be delivered to the Holder promptly
following the Conversion Date.
              
              (c)  Determination of Fair Market Value.  For
purposes of this Section 1.5, the fair market value of a share of
Common Stock on the Conversion Date shall be the average of the
closing prices of the Common Stock as reported on a Trading
Market (as defined below) for the last fifteen (15) trading day
period ending two (2) days prior to the Conversion Date.  For
purposes of this Warrant, "Trading Market" shall mean one of the
following which has been determined by the Company's Board of
Directors to be the Company's principal trading market:  NASD OTC
Bulletin Board, the Nasdaq SmallCap Market, the Nasdaq National
Market, the American Stock Exchange or the New York Stock
Exchange.  Notwithstanding the foregoing, in the event the Common
Stock is not publicly trading on the Conversion Date, the fair
market value of a share of Common Stock on the Conversion Date
shall be determined in good faith by the Company's Board of
Directors.
              
              (d)  Limit on Exercise.  Notwithstanding any other
provision of this Warrant, the Holder shall not be entitled to
exercise the Conversion Right, in whole or in part, unless the
Holder agrees, in writing, to immediately convert the Shares
issued pursuant to the Conversion Right into shares of the
Company's Common Stock (pursuant to the terms of the Company's
Amended and Restated Certificate of Incorporation and Certificate
of Designations, Preferences and Rights of Series C Preferred
Stock of the Company).

        2.  Adjustment of Exercise Price and Number of Shares.
The Exercise Price and the number of shares purchasable upon the
exercise of this Warrant shall be subject to adjustment from time
to time upon the occurrence of certain events described in this
Section 2.  Upon each adjustment of the Exercise Price, the
Holder of this Warrant shall thereafter be entitled to purchase,
at the Exercise Price resulting from such adjustment, the number
of shares obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of shares
purchasable pursuant hereto immediately prior to such adjustment,
and dividing the product thereof by the Exercise Price resulting
from such adjustment.

          2.1   Subdivision or Combination of Stock.  In case the
Company shall at any time subdivide its outstanding shares of
Series C Preferred Stock into a greater number of shares, the
Exercise Price in effect immediately prior to such subdivision
shall be proportionately reduced, and conversely, in case the
outstanding shares of Series C Preferred Stock of the Company
shall be combined into a smaller number of shares, the Exercise
Price in effect immediately prior to such combination shall be
proportionately increased.

          2.2   Dividends in Stock, Other Stock, Property,
Reclassification.  If at any time or from time to time the
holders of the Series C Preferred Stock (or any shares of stock
or other securities at the time receivable upon the exercise of
this Warrant) shall have received or become entitled to receive,
without payment therefor,

              (a)  Series C Preferred Stock, or any shares of
stock or other securities whether or not such securities are at
any time directly or indirectly convertible into or exchangeable
for Common Stock, or any rights or options to subscribe for,
purchase or otherwise acquire any of the foregoing by way of
dividend or other distribution, or
              
              (b)  any cash paid or payable otherwise than as a
cash dividend, or
              
              (c)  Series C Preferred Stock or other or
additional stock or other securities or property (including cash)
by way of spin off, split-up, reclassification, combination of
shares or similar corporate rearrangement, (other than shares of
Stock issued as a stock split, adjustments in respect of which
shall be covered by the terms of Section 2.1 above),

CUSIP No. 225235209                SCHEDULE 13D                Page 24 of 31

        Then and in each such case, the Holder hereof shall, upon
the exercise of this Warrant, be entitled to receive, in addition
to the number of shares of Stock receivable thereupon, and
without payment of any additional consideration therefore, the
amount of stock and other securities and property (including cash
in the cases referred to in clauses (b) and (c) above) which such
Holder would hold on the date of such exercise had he been the
holder of record of such Stock as of the date on which holders of
Series C Preferred Stock received or became entitled to receive
such shares and/or all other additional stock and other
securities and property.

          2.3   Reclassification or Reorganization.  If the Stock
(or any shares of stock or other securities which may be)
issuable upon the exercise of this Warrant shall be changed into
the same or different number of shares of any class or classes of
stock, whether by capital reorganization, reclassification or
otherwise (other than a subdivision or combination of shares or
stock dividend provided for in Section 2.1 above, or a Corporate
Transaction, in which case this Warrant shall terminate if not
exercised), then and in each such event the Holder shall be
entitled to receive upon the exercise of this Warrant the kind
and amount of shares of stock and other securities and property
receivable upon such reorganization, reclassification or other
change, to which a holder of the number of shares of Stock (or
any shares of stock or other securities which may be) issuable
upon the exercise of this Warrant would have received if this
Warrant had been exercised immediately prior to such
reorganization, reclassification or other change, all subject to
further adjustment as provided herein.

          2.4   Notice of Adjustments and Record Dates.  The
Company shall promptly notify the Holder in writing of each
adjustment or readjustment of the exercise price hereunder and
the number of shares of Stock (or any shares of stock or other
securities which may be) issuable upon the exercise of this
Warrant.  Such notice shall state the adjustment or readjustment
and show in reasonable detail the facts on which that adjustment
or readjustment is based.  In the event of any taking by the
Company of a record of the holders of Common Stock for the
purpose of determining the holders thereof who are entitled to
receive any dividend or other distribution, the Company shall
notify the Holder in writing of such record date at least twenty
(20) days prior to the date specified therein.

CUSIP No. 225235209                SCHEDULE 13D                Page 25 of 31

          2.5   Shares to be Fully Paid; Reservation of Shares.
The Company covenants and agrees that all shares of Stock which
may be issued upon the exercise of the rights represented by this
Warrant will, upon payment of the Exercise Price and issuance
pursuant to Section 1.4 or a net issuance pursuant to Section
1.5, be duly authorized, validly issued, fully paid and
nonassessable and free from all preemptive rights of any
stockholder and free of all taxes, liens and charges with respect
to the issue thereof.  The Company further covenants and agrees
that during the period within which the rights represented by
this Warrant may be exercised, the Company will at all times have
authorized and reserved, for the purpose of issue or transfer
upon exercise of the subscription rights evidenced by this
Warrant, a sufficient number of shares of authorized but unissued
Series C Preferred Stock and Common Stock into which such Series
C Preferred Stock may be converted, or other securities and
property, when and as required to provide for the exercise of the
rights represented by this Warrant.  The Company will take all
such action as may be necessary to assure that such shares of
Series C Preferred Stock and Common Stock may be issued as
provided herein without violation of any applicable law or
regulation.

        3.  Replacement of Warrants.  On receipt by the Company
of evidence reasonably satisfactory to the Company of the loss,
theft, destruction or mutilation of this Warrant and, in the case
of any such loss, theft or destruction of this Warrant, on
delivery of an indemnity agreement reasonably satisfactory in
form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of such Warrant, the
Company at its expense shall execute and deliver to the Holder,
in lieu thereof, a new Warrant of like tenor.

        4.  Investment Intent.  Unless a current registration
statement under the Securities Act, shall be in effect with
respect to the securities to be issued upon exercise of this
Warrant, the Holder, by accepting this Warrant, covenants and
agrees that, at the time of exercise hereof, and at the time of
any proposed transfer of any securities acquired upon exercise
hereof, the Holder shall deliver to the Company a written
statement that the securities acquired by the Holder upon
exercise hereof are for the own account of the Holder for
investment and are not acquired with a view to, or for sale in
connection with, any distribution thereof (or any portion
thereof) and with no present intention (at any such time) of
offering or distributing such securities (or any portion
thereof).

CUSIP No. 225235209                SCHEDULE 13D                Page 26 of 31

        5.  No Rights or Liability as a Shareholder.  This
Warrant does not entitle the Holder hereof to any voting rights
or other rights as a shareholder of the Company.  No provisions
hereof, in the absence of affirmative action by the Holder to
purchase Stock, and no enumeration herein of the rights or
privileges of the Holder, shall give rise to any liability of the
Holder as a shareholder of the Company.

        6.  Representations of Holder.  The Holder hereby
represents and acknowledges to the Company that:

          6.1   this Warrant, the Stock issuable upon exercise of
this Warrant and any securities issued with respect to any of
them by way of a stock dividend or stock split or in connection
with a recapitalization, merger, consolidation or other
reorganization will be "restricted securities" as such term is
used in the rules and regulations under the Securities Act, and
that such securities have not been and may not be registered
under the Securities Act or any state securities law, and that
such securities must be held indefinitely unless registration is
effected or transfer can be made pursuant to appropriate
exemptions;

          6.2   the Holder has read, and fully understands, the
terms of this Warrant set forth on its face and the attachments
hereto, including the restrictions on transfer contained herein;

          6.3   the Holder is purchasing for investment for its
own account and not with a view to or for sale in connection with
any distribution of this Warrant or the Stock of the Company
issuable upon exercise of this Warrant and it has no intention of
selling such securities in a public distribution in violation of
the federal securities laws or any applicable state securities
laws;

          6.4   the Company may affix the following legends (in
addition to any other legend(s), if any, required by applicable
state corporate and/or securities laws) to certificates for
shares of Stock (or other securities) issued upon exercise of
this Warrant ("Warrant Shares"):

               "These securities have not been registered
               under the Securities Act of 1933, as amended.
               They may not be sold, offered for sale,
               pledged or hypothecated in the absence of a
               registration statement in effect with respect
               to the securities under such Act or an
               opinion of counsel satisfactory to the
               Company that such registration is not
               required or unless sold pursuant to Rule 144
               of such Act."
               
        7.  Reserved.

        8.  Reserved.

        9.  Limitations on Disposition.  The Holder of this
Warrant, by acceptance hereof, agrees to comply in all respects
with the provisions of this Section 9.  Without in any way
limiting the representations set forth above, the Holder of this
Warrant agrees not to make any disposition of this Warrant or any
Warrant Shares, unless and until the transferee has agreed in
writing for the benefit of the Company to be bound by this
Section 9 and the other provisions of this Warrant as if such
transferee were the original Holder hereof, provided and to the
extent such provisions are then applicable, and

                (a)  There is then in effect a Registration
Statement under the Securities Act covering such proposed
disposition and such disposition is made in accordance with such
Registration Statement; or

                (b) (i) the Holder shall have notified the
Company of the proposed disposition and shall have furnished the
Company with a detailed statement of the circumstances
surrounding the proposed disposition, and the Company has given
its prior written consent (which consent shall not be
unreasonably withheld), and (ii) if reasonably requested by the
Company, the Holder shall have furnished the Company with an
opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of the Warrant
and/or the Warrant Shares under the Securities Act.  It is agreed
that the Company will not require opinions of counsel for
transactions made pursuant to Rule 144 except in unusual
circumstances.

        Notwithstanding any other provision of this Section 9,
Holder may transfer this Warrant and/or the Warrant Shares to any
investment fund in which MedCap Management & Research LLC or any
of its affiliates is the General Partner or the manager; provided
that, such fund is an "accredited investor" as such term is then
defined in Section 501 of Regulation D promulgated pursuant to
the Securities Act.

        10. Miscellaneous.

          10.1  Transfer of Warrant.  In addition to the transfer
restrictions set forth in Section 9, this Warrant shall not be
transferable or assignable in any manner and no interest shall be
pledged or otherwise encumbered by the Holder without the express
written consent of the Company.

          10.2  Titles and Subtitles.  The titles and subtitles
used in this Warrant are for convenience only and are not to be
