7.5                                Indemnification; Contribution .

(a)                                  Amicus shall indemnify and hold harmless each Holder (including the employees, agents, representatives, officers and directors of each Purchaser and its Affiliates) (each a “ Purchaser Indemnitee ”) from and against any and all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) arising out of or based upon any untrue, or allegedly untrue, statement of a material fact contained in any Registration Statement, prospectus or preliminary prospectus or notification or offering circular prepared by Amicus in connection with the registration and/or offering of the Registrable Securities (as amended or supplemented if Amicus shall have furnished any amendments or supplements thereto) or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information concerning such Holder furnished in writing to Amicus by such Holder specifically and expressly for inclusion in such document.

(b)                                  Each Holder shall indemnify and hold harmless Amicus, and its respective directors, officers, employees and each Person who controls Amicus (within the meaning of the Securities Act and the Exchange Act) from and against any and all losses, claims, damages, liabilities and expenses (including reasonable costs of investigation) arising out of or based upon any untrue, or allegedly untrue, statement of a material fact contained in any Registration Statement, prospectus or preliminary prospectus or notification or offering circular prepared by Amicus in connection with the registration and/or offering of the Registrable Securities (as amended or supplemented if Amicus shall have furnished any amendments or supplements thereto) or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, if such statement or omission was made in reliance upon and in conformity with any information concerning such Holder furnished in writing to Amicus by such Holder specifically and expressly for use in the preparation of such document.

(c)                                   Each Person entitled to indemnification hereunder (the “ Indemnified Party ”) agrees to give prompt written notice to the indemnifying party (the “ Indemnifying Party ”) after the receipt by the Indemnified Party of any written notice of the commencement of any action, suit, proceeding or investigation or threat thereof made in writing for which the Indemnified Party intends to claim indemnification or contribution pursuant to the Transaction Documents; provided, however , that the failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any liability that it may have to the Indemnified Party hereunder unless, and only to the extent that, such failure results in the Indemnifying Party’s forfeiture of substantive rights or defenses.  If notice of commencement of any such action is given to the Indemnifying Party as above provided, the Indemnifying Party shall be entitled to participate in and, to the extent it may wish, jointly with any other Indemnifying Party similarly notified, to assume the defense of such action at its own expense,

15

with counsel chosen by it and reasonably satisfactory to such Indemnified Party.  The Indemnified Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel (other than reasonable costs of investigation) shall be paid by the Indemnified Party unless (i) the Indemnifying Party agrees to pay the same, (ii) the Indemnifying Party fails to assume the defense of such action with counsel reasonably satisfactory to the Indemnified Party in its reasonable judgment or (iii) the named parties to any such action (including any impleaded parties) have been advised by such counsel that either (x) representation of such Indemnified Party and the Indemnifying Party by the same counsel would be inappropriate under applicable standards of professional conduct or (y) there may be one or more legal defenses available to it which are different from or additional to those available to the Indemnifying Party.  In either of such cases, the Indemnifying Party shall not have the right to assume the defense of such action on behalf of such Indemnified Party.  No Indemnifying Party shall be liable for any settlement entered into without its written consent (other than in the case where the Indemnifying Party is unconditionally released from liability and its rights are not adversely effected), which consent shall not be unreasonably withheld.

(d)                                  If the indemnification provided for in this Section 7.5 from the Indemnifying Party pursuant to applicable law is unavailable to an Indemnified Party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations.  The relative faults of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, Knowledge, access to information and opportunity to correct or prevent such action.  The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Sections 7.5(a), (b) and (c) , any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding.  The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 7.5(d)  were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph.  No Person guilty of an intentional or fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person.

7.6                                Rule 144 Reporting .  In order to make the benefits of the rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without registration available to the Holders, Amicus agrees to use commercially reasonable efforts to:

(a)                                  make and keep public information available, as those terms are understood and defined in Rule 144(c)(1) or any similar or analogous rule promulgated under the Securities Act, at all times after the SPA Effective Date;

16

(b)                                  file with the SEC, in a timely manner, all reports and other documents required of Amicus under the Exchange Act; and

(c)                                   so long as any Holder owns any Registrable Securities, furnish such Holders forthwith upon request: (i) a written statement by Amicus as to its compliance with the reporting requirements of Rule 144 under the Securities Act, and of the Exchange Act; (ii) a copy of the most recent annual or quarterly report of Amicus; and (iii) such other reports and documents as a Holder may reasonably request in availing itself of any rule of regulation of the SEC allowing it to sell any such securities without registration.

7.7                                Assignment of Registration Rights .  The rights and obligations under this Section 7 may only be assigned by a Holder to a transferee or assignee of Registrable Securities that is (a) an Affiliate or (b) a successor (by operation of law or otherwise) to substantially all the business or assets of such Holder; provided, however , that such attempted assignment shall be void unless (i) such Holder, within 30 days after such transfer, furnishes to Amicus written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned, and (ii) such transferee agrees to be subject to all obligations and restrictions with respect to the Registrable Securities set forth in this Agreement.

During the Lock-Up Period, each Purchaser agrees that in connection with any registration of Amicus’ securities that, upon the request of Amicus or the underwriters managing any underwritten offering of Amicus’ securities, not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Registrable Securities without the prior written consent of Amicus or such underwriters, as the case may be, for such period of time from the effective date of such registration as Amicus or the underwriters may specify, provided that each executive officer and director of Amicus agrees to a similar lockup.

8.3                                Remedies . Without prejudice to the rights and remedies otherwise available to the parties, Amicus shall be entitled to equitable relief by way of injunction if any Purchaser or any other Holder breaches or threatens to breach any of the provisions of this Section 8 .

10.3                         Execution .  This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by the Parties and delivered to the other Parties, it being understood that the Parties need not sign the same counterpart.  In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

18

may assign any or all of its rights under this Agreement to any Person to whom such Purchaser assigns or transfers any Securities, provided such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions of the Transaction Documents that apply to the “Purchasers.”

10.6                         Entire Agreement .  The Transaction Documents, together with the exhibits and schedules hereto, contain the entire understanding of the Parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written, with respect to such matters (other than confidentiality agreements to which Amicus is a party to with the Purchasers), which the Parties acknowledge have been merged into such documents, exhibits and schedules.

10.7                         Separability .  If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the Parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the Parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

10.8                         Rescission and Withdrawal Right .  Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and Amicus does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to Amicus, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

10.10                  Remedies .  In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and Amicus will be entitled to specific performance under the Transaction Documents.  The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agrees to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

19

10.11                  Independent Nature of Purchasers’ Obligations and Rights .  The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document.  Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents.  Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.  Each Purchaser has been represented by its own separate legal counsel in their review and negotiation of the Transaction Documents.

The rights represented by this Warrant may be exercised in whole or in part at any time during the Exercise Period, by delivery of the following to the Company at its address set forth on the signature page hereto (or at such other address as it may designate by notice in writing to the Holder):

(A)               an executed written notice, in the form attached hereto as Exhibit A (the “ Exercise Notice ”); and

(B)               payment of the Exercise Price in cash or by check.

The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares, if any.

Certificates for shares purchased hereunder shall be transmitted by the transfer agent of the Company to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company (“ DTC ”) through its Deposit Withdrawal Agent Commission system if the Company’s transfer agent is a participant in such system, and otherwise by physical delivery to the address specified by the Holder in the Exercise Notice, in each case within three business days from the delivery to the Company of the Exercise Notice and payment of the aggregate Exercise Price as set forth above. This Warrant shall be deemed to have been exercised on the date the Exercise Price is received by the Company.

The person in whose name any certificate or certificates for Warrant Shares are to be issued upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which payment of the Exercise Price was made, irrespective of the date such Warrant Shares are credited to the DTC account of the Holder’s prime

2

broker or the date of delivery of the certificate or certificates evidencing such Warrant Shares, as the case may be, except that, if the date of such payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the opening of business on the next succeeding date on which the stock transfer books are open.

Subject to Section 2.4 and the final sentence of this paragraph and to the extent permitted by law, the Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any person or entity or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other person or entity of any obligation to the Company or any violation or alleged violation of law by the Holder or any other person or entity, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares. The Holder shall have the right to pursue any remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver Warrant Shares upon exercise of this Warrant as required pursuant to the terms hereof.

2.1.            ISSUANCE OF NEW WARRANTS . Upon any partial exercise of this Warrant, the Company, at its expense, will forthwith and, in any event within five business days, issue and deliver to the Holder a new warrant or warrants of like tenor, registered in the name of the Holder, exercisable, in the aggregate, for the balance of the number of shares of the Common Stock remaining available for purchase under this Warrant.

2.2.               PAYMENT OF TAXES AND EXPENSES . The Company shall pay any recording, filing, stamp or similar tax which may be payable in respect of any transfer involved in the issuance of, and the preparation and delivery of certificates (if applicable) representing, (A) any Warrant Shares purchased upon exercise of this Warrant and/or (B) new or replacement warrants in the Holder’s name or the name of any transferee of all or any portion of this Warrant; provided , however , that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance, delivery or registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

2.3.            DISPUTES . In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed.

2.4.               EXERCISE LIMITATIONS; HOLDER’S RESTRICTIONS . A Holder, other than an Excluded Holder, shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise, such Holder (together with such Holder’s affiliates), as set forth on the applicable Exercise Notice, would beneficially own in excess of 19.9% of the number of shares of the Common Stock outstanding immediately after giving effect to such issuance. For purposes of this Section 2.4 , the number of shares of the Common Stock beneficially owned by such Holder and its affiliates shall include the number of shares of the Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude the number of shares of the Common Stock which would be issuable upon (A) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by such Holder or any of its affiliates and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other shares of the Common Stock or Warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such Holder or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 2.4 , beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), it being acknowledged by a Holder that the Company is not representing to such Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and such Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 2.4 applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by such Holder) and of which a portion of this Warrant is exercisable shall be in the sole discretion of a Holder, and the submission of an Exercise Notice shall be deemed to be each Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by such Holder) and of which portion of this Warrant is exercisable, in each case subject to such aggregate percentage limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination. For purposes of this Section 2.4 , in determining the number of outstanding shares of the Common Stock, a Holder may rely on the number of outstanding shares of the Common Stock as reflected in (x) the Company’s most recent Form 10-Q or Form 10-K, as the case may be, (y) a more recent public securities filing with the U.S. Securities and Exchange Commission by the Company or (z) any other announcement or notice by the Company or the Company’s transfer agent setting forth the number of shares of the Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to such Holder the number of shares of the Common Stock then outstanding. In any case, the number of outstanding shares of the Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by such Holder or its affiliates since the date as of which such number of outstanding shares of the Common Stock was reported. The provisions of this Section 2.4 may be waived by such Holder, at the election of such Holder, upon not less than 61 days’

4

prior notice to the Company, and the provisions of this Section 2.4 shall continue to apply until such 61 st  day (or such later date, as determined by such Holder, as may be specified in such notice of waiver). For purposes of this Section 2.4 , an “ Excluded Holder ” shall mean a Holder (together with such Holder’s affiliates) that beneficially owned in excess of 19.9% of the number of shares of the Common Stock outstanding on the date this Warrant was issued to such Holder; provided , however , that if thereafter such Holder (together with such Holder’s affiliates) shall beneficially own 19.9% or a percentage less than 19.9% of the number of shares of the Common Stock outstanding, then such Holder shall cease to be an “Excluded Holder” hereunder.

3.                                                      COVENANTS OF THE COMPANY .

3.1.            COVENANTS AS TO WARRANT SHARES . The Company covenants and agrees that all Warrant Shares that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued and outstanding, fully paid and nonassessable, and free from all taxes, liens and charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period have authorized and reserved, free from preemptive rights, a sufficient number of shares of the Common Stock to provide for the exercise of the rights represented by this Warrant. If at any time during the Exercise Period the number of authorized but unissued shares of the Common Stock shall not be sufficient to permit exercise of this Warrant, the Company will use its commercially reasonable efforts to take such corporate action in compliance with applicable law as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of the Common Stock to such number of shares as shall be sufficient for such purposes.

3.2.            NOTICES OF RECORD DATE AND CERTAIN OTHER EVENTS . In the event of any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, the Company shall mail to the Holder, at least 15 days prior to the date on which any such record is to be taken for the purpose of such dividend or distribution, a notice specifying such date. In the event of any voluntary dissolution, liquidation or winding up of the Company, the Company shall mail to the Holder, at least 15 days prior to the date of the occurrence of any such event, a notice specifying such date. In the event the Company authorizes or approves, enters into any agreement contemplating, or solicits stockholder approval for any Fundamental Transaction, as defined in Section 6 herein, the Company shall mail to the Holder, at least 15 days prior to the date of the occurrence of such event, a notice specifying such date. Notwithstanding the foregoing, the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice.

3.3               REGISTRATION RIGHTS .  The Warrant Shares issuable upon exercise of this Warrant are each Registrable Securities under the Purchase Agreement and

5

the registration rights set forth in Section 7 of the Purchase Agreement shall apply to the Warrant Shares.

4.                                                      ADJUSTMENT OF EXERCISE PRICE AND SHARES . The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 4 .

(A)               If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on the Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of the Common Stock, (ii) subdivides outstanding shares of the Common Stock into a larger number of shares, or (iii) combines outstanding shares of the Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of the Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of the Common Stock outstanding immediately after such event and the number of Warrant Shares issuable upon exercise of this Warrant shall be proportionately adjusted. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination.

(B)                      If the Company, at any time while this Warrant is outstanding, distributes to holders of the Common Stock (i) evidences of its indebtedness, (ii) any security (other than a distribution of the Common Stock covered by the preceding paragraph), (iii) rights or warrants to subscribe for or purchase any security, or (iv) any other asset (in each case, “ Distributed Property ”), then in each such case the Holder shall be entitled upon exercise of this Warrant for the purchase of any or all of the Warrant Shares, to receive the amount of Distributed Property which would have been payable to the Holder had such Holder been the holder of such Warrant Shares on the record date for the determination of stockholders entitled to such Distributed Property. The Company will at all times set aside in escrow and keep available for distribution to such holder upon exercise of this Warrant a portion of the Distributed Property to satisfy the distribution to which such Holder is entitled pursuant to the preceding sentence.

(C) Upon the occurrence of each adjustment pursuant to this Section 4 , the Company at its expense will, promptly provide written notice thereof to the Holder and, at the written request of the Holder, promptly compute such adjustment in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written

6

request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s transfer agent.

(D)                      No adjustment in the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least $0.0001; provided , however , that any adjustments which by reason of this Section 4(D)  are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided, further, however, that adjustments shall be required and made in accordance with the provisions of this Section 4 (other than this Section 4(D) ) not later than such time as may be required in order to preserve the tax-free nature of a distribution, if any, to the Holder of this Warrant or the Warrant Shares issuable upon the exercise hereof. All calculations under this Section 4 shall be made to the $0.0001 or to the nearest 1/1000th of a share, as the case may be. Anything in this Section 4 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Exercise Price, in addition to those required by this Section 4 , as it in its discretion shall deem to be advisable in order that any stock dividend, subdivision of shares or distribution of rights to purchase stock or securities convertible or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable.

5.                                                      FRACTIONAL SHARES . No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Warrant Shares (including fractions) issuable upon exercise of this Warrant may be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the number of Warrant Shares to be issued will be rounded down to the nearest whole share.

6.                                                      FUNDAMENTAL TRANSACTIONS . If any capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with another entity in which the Company is not the surviving corporation, or sale, transfer or other disposition of all or substantially all of the Company’s assets to another entity shall be effected (any such transaction being hereinafter referred to as a “ Fundamental Transaction ”), then the Holder shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares immediately theretofore issuable upon exercise of this Warrant, such shares of stock, securities or assets as would have been issuable or payable with respect to or in exchange for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of this Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of the Holder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Exercise Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any share of stock, securities or assets thereafter deliverable upon the exercise thereof. The Company shall not effect any such consolidation, merger, sale, transfer or other disposition unless prior

7

to or simultaneously with the consummation thereof the successor entity (if other than the Company) resulting from such consolidation or merger, or the entity purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Holder, at the last address of the Holder appearing on the books of the Company, such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Holder may be entitled to purchase, and the other obligations under this Warrant. Notice of any such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition and of said provisions so proposed to be made, shall be mailed to the Holders of the Warrants not less than 20 days prior to such event. The provisions of this Section 6 shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales, transfers or other dispositions, each of which transactions shall also constitute a Fundamental Transaction.

7.                                                      NONCIRCUMVENTION .  The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant. Without limiting the generality of the foregoing, the Company (A) shall not increase the par value of any shares of the Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (B) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of the Common Stock upon the exercise of this Warrant, and (C) shall, so long as this Warrant is outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of the Common Stock, solely for the purpose of effecting the exercise of this Warrant, 100% of the Warrant Shares issuable upon exercise of this Warrant then outstanding (without regard to any limitations on exercise).

8.                                                      NO STOCKHOLDER RIGHTS . Other than as provided in Section 3.2 or otherwise herein, this Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a stockholder of the Company.

9.                                                      TRANSFER OF WARRANT .

(A)                      Transferability . Subject to compliance with any applicable securities laws and the conditions set forth in Section 9(D) , this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto as Exhibit B duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer.

8

assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. A Warrant, if properly assigned, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

(D)                      Transfer Restrictions . If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not be registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such transfer, that (i) the Holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that such transfer may be made without registration under the Securities Act and under applicable state securities or blue sky laws, and (ii) the Holder or transferee execute and deliver to the Company an investment letter in form and substance acceptable to the Company, and (iii) the transferee be an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), or (a)(8) promulgated under the Securities Act or a “qualified institutional buyer” as defined in Rule 144A(a) promulgated under the Securities Act.

10.                                               LOST, STOLEN, MUTILATED OR DESTROYED WARRANT . If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.
