The Collateral Agent may so file and record this Agreement as a “security interest”, “collateral assignment”, “assignment” or similar designation as the Collateral Agent may determine (so long as such designation is consistent with the terms of this Agreement) and the Collateral Agent may from time to time rerecord and refile or take other action to change the designation under which this Agreement is filed or recorded (so long as such designation is consistent with the terms of this Agreement).

(c) Other Powers. The Grantor also authorizes the Collateral Agent, at any time and from time to time, to execute, in connection with the sale provided for herein, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral.

(d) No Duty on Collateral Agent’s Part. The powers conferred on the Collateral Agent hereunder are solely to protect the Collateral Agent’s interests in the Collateral for the ratable benefit of the Holders and shall not impose any duty upon the Collateral Agent to exercise any such powers. The Collateral Agent shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither it nor any of its officers, directors, employees or agents shall be responsible to the Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

(e) Grantor Remains Liable under Contracts. Anything herein to the contrary notwithstanding, the Grantor shall remain liable under each of the ontracts that constitute part of the Collateral to observe and perform all the conditions and obligations to be observed and performed by it thereunder, all in accordance with and pursuant to the terms and provisions of each such Contract. The Collateral Agent shall not have any obligation or liability under any Contract that constitutes part of the Collateral by reason of or arising out of this Agreement or the receipt by the Collateral Agent of any payment relating to such Contract pursuant hereto, nor shall the Collateral Agent be obligated in any manner to perform any of the obligations of the Grantor under or pursuant to any such Contract, to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party under any such Contract, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

6. Performance by Collateral Agent of Grantor’s Obligations. If the Grantor fails to perform or comply with any of its agreements contained herein and the Collateral Agent, as provided for by the terms of this Agreement and following reasonable notice to the Grantor, may itself perform or comply, or otherwise cause performance or compliance, with such agreement, and the expenses of the Collateral Agent incurred in connection with such performance or compliance shall be payable by the Grantor to the Collateral Agent on demand and shall constitute Obligations secured hereby.

7. Remedies. If an Event of Default has occurred and is continuing, but in the case of Events of Default that are solely ones covered by the final clause (2) of Section 4.01 of any Note, only after the expiration of the 120-day period specified in such clause (2) the Collateral Agent may exercise, in addition to all other rights and remedies granted to it in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the Code. Without limiting the generality of the foregoing, if an Event of Default has occurred and is continuing, but in the case of Events of Default that are solely ones covered by the final clause (2) of Section 4.01 of any Note, only after the expiration of the 120-day period specified in such clause (2) the Collateral Agent, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below or expressly provided for) to or upon the Grantor or any other Person (all and each of which demands, defenses, advertisements and notices are, to the extent permitted by applicable law, hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, license, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), at public or private sale or sales, at any exchange, broker’s board or office of the Collateral Agent or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Collateral Agent shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in the Grantor, which right or equity is hereby waived, to the extent permitted by applicable law, or released.

The Grantor further agrees, if an Event of Default has occurred and is continuing, at the Collateral Agent’s request, to assemble the Collateral and make it available to the Collateral Agent at places which the Collateral Agent shall reasonably select, whether at the Grantor’s premises or elsewhere. The Collateral Agent shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Collateral Agent hereunder, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Collateral Agent may elect, and only after such application and after the payment by the Collateral Agent of any other amount required by any provision of law, need the Collateral Agent account for the surplus, if any, to the Grantor. To the extent permitted by applicable law, the Grantor waives all claims, damages and demands it may acquire against the Collateral Agent arising out of the exercise by it of any rights hereunder, provided, that nothing contained in this Section shall relieve the Collateral Agent from liability arising solely from its gross negligence or willful misconduct. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least ten days before such sale or other disposition. The Grantor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Collateral Agent to collect such deficiency.

8. Limitation on Duties Regarding Preservation of Collateral. The Collateral Agent’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under the Code or otherwise, shall be to deal with it in the same manner as the Collateral Agent deals with similar property for its own account. Neither the Collateral Agent nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Grantor or otherwise.

9. Powers Coupled with an Interest. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest until the Grantor has paid and performed in full all of the Obligations.

10. Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

11. Paragraph Headings, Captions, Etc. The paragraph headings, the captions and the footers, used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

12. No Waiver; Cumulative Remedies. The Collateral Agent shall not by any act, delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the Collateral Agent, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Collateral Agent of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Collateral Agent would otherwise have on any future occasion. The rights and remedies herein and in the other Transaction Documents provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law or in equity or by statute.

13. Waivers and Amendments; Successors and Assigns. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the party to be charged with enforcement; provided, however, that any provision of this Agreement may be waived, amended, supplemented or otherwise modified by the Collateral Agent only with the prior written approval of the Majority Holders. This Agreement shall be binding upon the successors and assigns of the Grantor and shall inure to the benefit of the Collateral Agent and its successors and assigns. The Grantor may not assign its rights or obligations under this Agreement without the prior written consent of the Collateral Agent, which the Collateral Agent may withhold in the discretion of the Majority Holders. The requirements for resignation, and appointment of a successor to, the Collateral Agent are established by Exhibit D hereto and not by this Agreement.

14. Termination of Security Interest; Release of Collateral. (a) Upon the payment and performance in full by the Grantor of the Obligations, all right, title and interest of the Collateral Agent in and to the Collateral, including the Security Interest, pursuant to this Agreement shall terminate and all rights to the Collateral shall revert to the Grantor.

(b) At any time and from time to time prior to termination of the right, title and interest of the Collateral Agent in and to the Collateral pursuant to Section 14(a), the Collateral Agent shall release any of the Collateral only with the prior written consent of the Majority Holders.

(c) Upon any such termination of the Security Interest, the Collateral Agent will, at the expense of the Grantor, execute and deliver to the Grantor such documents and take such other actions as the Grantor shall reasonably request to evidence the reassignment of the Collateral to the Grantor and the termination of the Security Interest. The Collateral Agent shall deliver to the Grantor all Collateral so released then in its possession.

15. Notices. Any notices required or permitted to be given under the terms of this Agreement shall be in writing and shall be sent by mail, personal delivery, telephone line facsimile transmission or courier and shall be effective five days after being placed in the mail, if mailed, or upon receipt, if delivered personally, by telephone line facsimile transmission or by courier, in each case addressed to a party at such party’s address (or telephone line facsimile transmission number) shown below or such other address (or telephone line facsimile transmission number) as a party shall have provided by notice to the other party in accordance with this provision.

16. Fees and Expenses. The Grantor agrees to pay the fees of the Collateral Agent in performing its services under this Agreement and all reasonable expenses (including but not limited to attorneys’ fees and costs for legal services, costs of insurance and payments of taxes or other charges) of, or incidental to, the custody, care, sale or realization on any of the Collateral or in any way relating to the performance of the obligations or the enforcement or protection of the rights of the Collateral Agent hereunder.

17. Concerning Collateral Agent. The Grantor acknowledges that the rights and responsibilities of the Collateral Agent under this Agreement with respect to any action taken by the Collateral Agent or the exercise or

nonexercise by the Collateral Agent of any option, right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Collateral Agent and the Holders, be governed by Exhibit D to this Agreement and by such other agreements with respect thereto as may exist from time to time among them, but, as between the Collateral Agent and the Grantor, except as expressly provided in Sections 13 and 14, the Collateral Agent shall be conclusively presumed to be acting as agent for the Holders with full and valid authority so to act or refrain from acting, and the Grantor shall not be under any obligation to make any inquiry respecting such authority. The Collateral Agent hereby waives for the benefit of the Holders any claim, right or Lien of the Collateral Agent against the Collateral arising under applicable law or arising from any business or transaction between the Collateral Agent and the Grantor other than pursuant to this Agreement or any of the other Transaction Documents.

18. Survival. All representations, warranties, covenants and agreements of the Grantor and of the Collateral Agent contained herein will survive the execution and delivery hereof and the release of any Collateral pursuant hereto and shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Collateral Agent or the Grantor or any person who controls the Collateral Agent or the Grantor.

19. Grantor’s Obligations Absolute, Etc. The obligations of the Grantor under this Agreement shall be absolute and unconditional and shall remain in full force and effect without regard to, and shall not be released, suspended, discharged, terminated or otherwise affected by, any circumstance or occurrence whatsoever, including, without limitation: (a) any renewal, extension, amendment or modification of or addition or supplement to or deletion from any of the Transaction Documents or any other agreement or instrument referred to therein, or any assignment or transfer of any thereof; (b) any waiver, consent, extension, indulgence or other action or inaction under or in respect of any such Transaction Document or other agreement or instrument; (c) any furnishing of any additional security to the Collateral Agent or its assignees or any acceptance thereof or any release of any security by the Collateral Agent or its assignees; (d) any limitation on any party’s liability or obligations under any such Transaction Document or other agreement or instrument or any invalidity or unenforceability, in whole or in part, of any such Transaction Document or other agreement or instrument or any term thereof; or (e) any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution, liquidation or other like proceeding relating to the Grantor, or any action taken with respect to this Agreement by any trustee or receiver, or by any court, in any such proceeding, whether or not the Grantor shall have notice or knowledge of any of the foregoing.

20. Integration. This Agreement and the Security Agreement represent the entire agreement of the Grantor and the Collateral Agent with respect to the subject matter hereof, and there are no promises, undertakings,

representations or warranties by the Collateral Agent relative to subject matter hereof not expressly set forth or referred to herein or therein.

21. Counterparts; Execution. This Agreement may be executed in any number of counterparts and all the counterparts taken together shall be deemed to constitute one and the same instrument. This Agreement, once executed by a party, may be delivered to the other party hereto by telephone line facsimile transmission of a copy of this Agreement bearing the signature of the party so delivering this Agreement.

22. Governing Law.

EXHIBIT D

The Collateral Agent

1. Appointment. The Holders (all capitalized terms used in this Exhibit D and not otherwise defined shall have the respective meanings provided in the Patent and Trademark Security Agreement to which this Exhibit D is attached (the “Patent and Trademark Security Agreement”)), by their acceptance of the benefits of the Patent and Trademark Security Agreement, hereby irrevocably designate Alexandra Global Master Fund Ltd., as Collateral Agent, to act as specified herein and in the Patent and Trademark Security Agreement. Each Buyer hereby irrevocably authorizes, and each other Holder of any Note by the acceptance of such Note shall be deemed irrevocably to authorize, the Collateral Agent to take such action on its behalf under the provisions of the Patent and Trademark Security Agreement and any other instruments and agreements referred to herein or therein and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of the Collateral Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto. The Collateral Agent may perform any of its duties hereunder by or through its agents or employees.

2. Nature of Duties. The Collateral Agent shall have no duties or responsibilities except those expressly set forth in the Patent and Trademark Security Agreement. Neither the Collateral Agent nor any of its officers, directors, employees or agents shall be liable for any action taken or omitted by it as such under the Patent and Trademark Security Agreement or hereunder or in connection herewith or therewith, unless caused by its or their gross negligence or willful misconduct. The duties of the Collateral Agent shall be mechanical and administrative in nature; the Collateral Agent shall not have by reason of the Patent and Trademark Security Agreement or any other Transaction Document a fiduciary relationship in respect of any Holder; and nothing in the Patent and Trademark Security Agreement, expressed or implied, is intended to or shall be so construed as to impose upon the Collateral Agent any obligations in respect of the Patent and Trademark Security Agreement except as expressly set forth herein. The Collateral Agent shall not take any material action or exercise any material right or power pursuant to Section 5, 6 or 7 of this Agreement without the authorization or direction of the Majority Holders; provided, however, that if the Collateral Agent determines that it is unable to contact the Majority Holders for purposes of seeking such authorization or direction or time will not permit the Collateral Agent to so contact the Majority Holders prior to such time as detriment may occur to the rights of the Collateral Agent or the Holders from any failure of the Collateral Agent to act or exercise such right, then in any such case the Collateral Agent may take such action or exercise such right without specific authorization or direction from the Majority Holders.

D-1

The Collateral Agent shall not be liable for any act it may do or omit to do while acting in good faith and in the exercise of its own best judgment. Any act done or omitted by the Collateral Agent on the advice of its own attorneys shall be deemed conclusively to have been done or omitted in good faith. The Collateral Agent shall have the right at any time to consult with counsel on any question arising under this Patent and Trademark Security Agreement. The Collateral Agent shall incur no liability for any delay reasonably required to obtain the advice of counsel.

3. Lack of Reliance on the Collateral Agent. Independently and without reliance upon the Collateral Agent, each Holder, to the extent it deems appropriate, has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of the Grantor and its subsidiaries in connection with the making and the continuance of the Obligations and the taking or not taking of any action in connection therewith, and (ii) its own appraisal of the creditworthiness of the Grantor and its subsidiaries, and the Collateral Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Holder with any credit or other information with respect thereto, whether coming into its possession before any Obligation arises or the purchase of any Note, or at any time or times thereafter. The Collateral Agent shall not be responsible to any Holder for any recitals, statements, information, representations or warranties herein or in any document, certificate or other writing delivered in connection herewith or for the execution, effectiveness, genuineness, validity, enforceability, perfection, collectibility, priority or sufficiency of the Patent and Trademark Security Agreement or the financial condition of the Grantor or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of the Patent and Trademark Security Agreement, or the financial condition of the Grantor, or the existence or possible existence of any Event of Default.

4. Certain Rights of the Collateral Agent. No Holder shall have the right to cause the Collateral Agent to take any action with respect to the Collateral, with only the Majority Holders having the right to direct the Collateral Agent to take any such action. If the Collateral Agent shall request instructions from the Majority Holders with respect to any act or action (including failure to act) in connection with the Patent and Trademark Security Agreement, the Collateral Agent shall be entitled to refrain from such act or taking such action unless and until it shall have received instructions from the Majority Holders, and to the extent requested, appropriate indemnification in respect of actions to be taken by the Collateral Agent; and the Collateral Agent shall not incur liability to any person by reason of so refraining. Without limiting the foregoing, no Holder shall have any right of action whatsoever against the Collateral Agent as a result of the Collateral Agent acting or refraining from acting hereunder in accordance with the instructions of the Majority Holders or as otherwise specifically provided in the Patent and Trademark Security Agreement.

D-2

5. Reliance. The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, radiogram, order or other document or telephone message signed, sent or made by the proper person or entity, and, with respect to all legal matters pertaining to the Patent and Trademark Security Agreement and its duties thereunder, upon advice of counsel selected by it.

6. Limitation of Holder Liability. The Holders shall not be liable for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against the Collateral Agent in performing its duties hereunder or under the Patent and Trademark Security Agreement.

7. The Collateral Agent in its Individual Capacity. The Collateral Agent and its affiliates may lend money to, purchase, sell and trade in securities of and generally engage in any kind of business with the Grantor or any affiliate or subsidiary of the Grantor as if it were not performing the duties specified herein, and may accept fees and other consideration from the Grantor for services to the Grantor in connection with the Transaction Documents and otherwise without having to account for the same to the Holders; provided, however, that the Collateral Agent on behalf of itself and such affiliates, hereby waives any claim, right or Lien against the Collateral in any way arising from or relating to any such loan, securities transaction or business with the Grantor.

8. Holders. The Collateral Agent may deem and treat the holder of record of any Note as the owner thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof, as the case may be, shall have been filed with the Collateral Agent. Any request, authority or consent of any person or entity who, at the time of making such request or giving such authority or consent, is the holder of record of any Note shall be conclusive and binding on any subsequent holder, transferee or assignee, as the case may be, of such Note or of any Note(s) issued in exchange therefor.

9. Resignation by the Collateral Agent. (a) The Collateral Agent may resign from the performance of all its functions and duties under the Patent and Trademark Security Agreement at any time by giving 60 Business Days’ prior written notice (as provided in the Patent and Trademark Security Agreement) to the Grantor and the Holders. Such resignation shall take effect upon the appointment of a successor Collateral Agent pursuant to clauses (b) and (c) below.

D-3

(b) Upon any such notice of resignation, the Majority Holders shall appoint a successor Collateral Agent hereunder.

(c) If a successor Collateral Agent shall not have been so appointed within said 60 Business Day period, the Collateral Agent shall then appoint a successor Collateral Agent who shall serve as Collateral Agent hereunder or thereunder until such time, if any, as the Majority Holders appoint a successor Collateral Agent as provided above. If a successor Collateral Agent has not been appointed within such 60-day period, the Collateral Agent may petition any court of competent jurisdiction or may interplead the Grantor and Holders in a proceeding for the appointment of a successor Collateral Agent, and all fees, including but not limited to extraordinary fees associated with the filing of interpleader, and expenses associated therewith shall be payable by the Grantor.

(d) The fees of any successor Collateral Agent for its services as such shall be payable by the Grantor.
