SECTION II

COLLATERAL; OBLIGATION SECURED

Section 2.1 Grant and Description. In order to secure the full and complete payment and performance of the Obligations when due, the Company hereby grants to the Collateral Agent (as defined below) for the benefit of each Secured Party, subject to the Permitted Liens, a first priority security interest in all of the Company’s rights, titles, and interests in and to the Collateral (the “Security Interest”) and subject to the Permitted Liens, pledges, collaterally transfers, and assigns the Collateral to the Collateral Agent for the benefit of the Secured Parties, all upon and subject to the terms and conditions of this Security Agreement; provided, however, that the Collateral Agent and each Secured Party shall subordinate from time to time upon the Company’s request its Security Interests granted in such Collateral to any Lien(s) granted by the Company or any of its Subsidiaries to unaffiliated third parties which constitutes Permitted Liens contemplated within clauses (h) through (j) of the definition of Permitted Liens. If the grant, pledge, or collateral transfer or assignment of any specific item of the Collateral is expressly prohibited by any contract or by law, then the Security Interest created hereby nonetheless remains effective to the extent allowed by such contract, the UCC or other applicable laws, but is otherwise limited by that prohibition. The Security Interest granted herein shall terminate in accordance with Section 8.1 hereof.

Section 2.2 Financing Statements; Further Assurances.

(a) The Secured Parties hereby: (i) designate the Lead Investor as the representative of the Secured Parties (the “Collateral Agent”) to act on behalf of the Secured Parties as their representative in accordance with the terms of the Security Agreement with respect to the filing of any initial financing statements and amendments thereto, and any termination statements thereof; (ii) agree and consent that the Collateral Agent be named as the sole secured party on any and all financing statements and security agreements filed pursuant to this Security Agreement for the ratable benefit of all the Secured Parties; and (iii) agree that the Collateral Agent is authorized to file any and all terminations of such financing statements at such time or times as it determines is appropriate pursuant to the Security Agreement.

(b) As soon as practicable following the execution and delivery of this Agreement and upon the authorization of the Collateral Agent on behalf of the Secured Parties, the Company shall:

(i) file with the State of Delaware and any other offices that the Collateral Agent may reasonably request in writing an initial financing statement that (i) indicates the Collateral in a manner consistent with the definition of the term “Collateral” as contained in this Agreement, and (ii) contains any other information required by Article 9 of the UCC of the state or such jurisdiction for the sufficiency or filing office acceptance of any financing statement or amendment, including whether the Company is an organization, the type of organization, and any organization identification number issued to the Company;

(ii) file with the U.S. Patent and Trademark Office, such financing statements and/or patent security agreements in the form necessary to record the Liens granted hereunder on the Company’s patents and patent applications; and

(iii) upon the reasonable request of the Collateral Agent, file such additional financing statements and other documents, including amendments to the financing statements, in order to maintain the Liens in the Collateral.

(c) Until the Obligations are paid and performed in full, the Company covenants and agrees that it will, at its own expense and upon the request of the Majority in Interest or the Collateral Agent, but in all cases subject to the rights of the grantees of the Permitted Liens: (i) after an Event of Default, file or cause to be filed such applications and take such other actions as the Majority in Interest or a duly appointed Collateral Agent may reasonably request to obtain the consent or approval of any governmental authority to the rights of the Secured Parties and the Collateral Agent hereunder, including, without limitation, the right to sell all the Collateral upon an Event of Default without additional consent or approval from such governmental authority; (ii) from time to time, either before or after an Event of Default, promptly execute and deliver to the duly appointed Collateral Agent all such other assignments, certificates, supplemental documents, and financing statements, and do all other acts or things as the Majority in Interest or duly appointed Collateral Agent may reasonably request in order to more fully create, evidence, perfect, continue, and preserve the priority of the Security Interest and to carry out the provisions of this Agreement; and (iii) either before or after an Event of Default, pay all filing fees in connection with any financing, continuation, or termination statement or other instrument with respect to the Security Interest.

Section 2.3 Priority. The Secured Parties and Collateral Agent hereby covenant and agree with the Company that the Company has granted and may subsequently grant, from time to time, Permitted Liens and that the security interest granted to the Secured Parties and the Collateral Agent in the Collateral hereunder is (i) subordinated to the respective Permitted Liens in the Collateral that was granted and remains outstanding immediately prior to the date hereof (the “Senior Permitted Liens”) or as contemplated in Section 2.1, above; (ii) senior to other Liens granted by the Company in the Collateral after the date hereof; and (iii) that as between all Secured Parties, the Security Interest granted to each Secured Party under this Agreement is pari passu with the Security Interests of the other Secured Parties; provided, however, that the portion of each Secured Party’s Security Interest that corresponds to the portion of its Subscription Amount paid by surrendering and cancelling Prior Notes pursuant to the Purchase Agreement shall be subordinated to the Security Interests held by it and the other Secured Parties that correspond to the Subscription Amounts paid in cash. The priorities specified herein are applicable irrespective of the time, order or method of attachment or perfection of security interests or the time or order of filing of financing statements. The Secured Parties agree not to seek to challenge, to avoid, to subordinate or to contest or directly or indirectly to support any other Person in challenging, avoiding, subordinating or contesting in any judicial or other proceeding, including, without limitation, any proceeding involving the Company, the priority, validity, extent, perfection or enforceability of any Senior Permitted Liens in all or any part of the Collateral. The Secured Parties further covenant and agree that they shall not, and they shall not instruct, authorize or otherwise permit or consent to allowing the Collateral Agent to, take any action that is in violation of, or inconsistent with, the provisions of this section.

Independently and without reliance upon the Collateral Agent, each Secured Party, 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 Company and its subsidiaries in connection with such Secured Party’s investment in the Company, the creation and continuance of the Obligations, the transactions contemplated by the Transaction Documents, and the taking or not taking of any action in connection therewith, and (ii) its own appraisal of the creditworthiness of the Company and its subsidiaries, and of the value of the Collateral from time to time, and the Collateral Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Secured Party with any credit, market or other information with respect thereto, whether coming into its possession before any Obligations are incurred or at any time or times thereafter. The Collateral Agent shall not be responsible to the Company or any Secured Party 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 Agreement or any other Transaction Document, or for the financial condition of the Company or the value of any of the Collateral, or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of the Agreement or any other Transaction Document, or the financial condition of the Company, or the value of any of the Collateral, or the existence or possible existence of any default or Event of Default under the Agreement, the Debentures or any of the other Transaction Documents.

Section 7.4 Certain Rights of the Collateral Agent. The Collateral Agent shall have the right to take any action with respect to the Collateral permitted by this Agreement, on behalf of all of the Secured Parties. To the extent practical, the Collateral Agent shall request instructions from the Secured Parties with respect to any material act or action (including failure to act) in connection with the Agreement or any other Transaction Document, and shall be entitled to act or refrain from acting in accordance with the instructions of a Majority in Interest; if such instructions are not provided despite the Collateral Agent’s request therefor, the Collateral Agent shall be entitled to refrain from such act or taking such action, and if such action is taken, shall be entitled to appropriate indemnification from the Secured Parties in respect of actions to be taken by the Collateral Agent; and the Collateral Agent shall not incur liability to any person or entity by reason of so refraining. Without limiting the foregoing, (a) no Secured Party 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 terms of the Agreement or any other Transaction Document, and the Company shall have no right to question or challenge the authority of, or the instructions given to, the Collateral Agent pursuant to the foregoing and (b) the Collateral Agent shall not be required to take any action which the Collateral Agent believes (i) could reasonably be expected to expose it to personal liability or (ii) is contrary to this Agreement, the Transaction Documents or applicable law.

Section 7.5 Reliance. The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any 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 Agreement and the other Transaction Documents and its duties thereunder, upon advice of counsel selected by it and upon all other matters pertaining to this Agreement and the other Transaction Documents and its duties thereunder, upon advice of other experts selected by it. Anything to the contrary notwithstanding, the Collateral Agent shall have no obligation whatsoever to any Secured Party to assure that the Collateral exists or is owned by the Company or is cared for, protected or insured or that the liens granted pursuant to the Agreement have been properly or sufficiently or lawfully created, perfected, or enforced or are entitled to any particular priority.

Section 7.6 Indemnification. To the extent that the Collateral Agent is not reimbursed and indemnified by the Company, the Secured Parties will jointly and severally reimburse and indemnify the Collateral Agent, in proportion to their initially purchased respective principal amounts of Debentures, from and against any and all 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 Agreement or any other Transaction Document, or in any way relating to or arising out of the Agreement or any other Transaction Document except for those determined by a final judgment (not subject to further appeal) of a court of competent jurisdiction to have resulted solely from the Collateral Agent’s own gross negligence or willful misconduct. Prior to taking any action hereunder as Collateral Agent, the Collateral Agent may require each Secured Party to deposit with it sufficient sums as it determines in good faith is necessary to protect the Collateral Agent for costs and expenses associated with taking such action.

Section 7.7 Resignation by the Collateral Agent.

(a) The Collateral Agent may resign from the performance of all its functions and duties under the Agreement and the other Transaction Documents at any time by giving 30 days’ prior written notice (as provided in the Agreement) to the Company and the Secured Parties. Such resignation shall take effect upon the appointment of a successor Collateral Agent pursuant to clauses (b) and (c) below.

(b) Upon any such notice of resignation, the Secured Parties, acting by a Majority in Interest, shall appoint a successor Collateral Agent hereunder.

(c) If a successor Collateral Agent shall not have been so appointed within said 30-day period, the Collateral Agent shall then appoint a successor Collateral Agent who shall serve as Collateral Agent until such time, if any, as the Secured Parties appoint a successor Collateral Agent as provided above. If a successor Collateral Agent has not been appointed within such 30-day period, the Collateral Agent may petition any court of competent jurisdiction or may interplead the Company and the Secured Parties 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 Company on demand.

Section 7.8 Rights with respect to Collateral. Each Secured Party agrees with all other Secured Parties and the Collateral Agent (i) that it shall not, and shall not attempt to, independently exercise any rights with respect to its security interest in the Collateral, whether pursuant to any other agreement or otherwise (other than pursuant to this Agreement), or take or institute any action against the Collateral Agent or any of the other Secured Parties in respect of the Collateral or its rights hereunder (other than any such action arising from the breach of this Agreement) and (ii) that such Secured Party has no other rights with respect to the Collateral other than as set forth in this Agreement and the other Transaction Documents. Upon the acceptance of any appointment as Collateral Agent hereunder by a successor Collateral Agent, such successor Collateral Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent and the retiring Collateral Agent shall be discharged from its duties and obligations under the Agreement. After any retiring Collateral Agent’s resignation or removal hereunder as Collateral Agent, the provisions of the Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Collateral Agent.

SECTION VIII

MISCELLANEOUS

Section 8.1 Termination and Release. This Agreement, and the Liens created by this Agreement shall automatically terminate in all respects upon the full and final payment by the Company of the Debentures or the conversion of the Debentures into shares of capital stock of the Company, in accordance with the terms of the Debentures. Further, the Liens created by this Agreement on any of the Collateral shall be automatically released if the Company disposes of such Collateral pursuant to a transaction permitted by the Debentures or otherwise consented to by the Collateral Agent or the Majority in Interest. In connection with any termination or release pursuant to this Section 8.1, the Majority in Interest shall, or shall cause any duly appointed Collateral Agent to, promptly execute and deliver to the Company all documents that the Company shall reasonably request to evidence such termination or release.

Section 8.2 Severability. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision; provided, that in such case the parties shall negotiate in good faith to replace such provision with a new provision which is not illegal, unenforceable or void, as long as such new provision does not materially change the economic benefits of this Agreement to the parties.

Section 8.3 Continuing Security Interest; Successors. This Agreement creates a continuing security interest in the Collateral and shall (i) remain in full force and effect until the Obligations are paid and performed in full or this Agreement is sooner terminated in accordance with Section 8.1; and (ii) inure to the benefit of and be enforceable by Secured Parties and their successors, transferees, and assigns. Each Secured Party may assign its rights hereunder in connection with any private sale or transfer of its Debenture in accordance with the terms of the Purchase Agreement and applicable law, in which case the term “Secured Party” shall be deemed to refer to such transferee as though such transferee was an original signatory hereto.

Section 8.4 Governing Law; Jurisdiction. This Agreement shall be governed by and construed under the laws of the State of New York applicable to contracts made and to be performed entirely within the State of New York. The Company hereby irrevocably submit to the non-exclusive jurisdiction of the state and federal courts sitting in the City of New York, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waive, and agree not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper.

Section 8.5 Headings. The headings used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

Section 8.6 Notices. Any notice to the Company or to a Secured Party shall be given in the manner set forth in the Purchase Agreement; provided that a Secured Party, if not a party to such Purchase Agreement, shall provide the Company with its proper delivery instructions for notices. Either party may, by notice given in accordance with the Purchase Agreement, change the address to which notices, demands and requests shall be sent to such party. Any notice to be given by the Company to the Collateral Agent shall be given in the manner provided for in the Purchase Agreement, and delivered to such address as the Company is instructed by the Collateral Agent.

Section 8.7 Entire Agreement; Amendments; Waivers. This Agreement constitutes the entire agreement between the parties with regard to the subject matter hereof and thereof, superseding all prior agreements or understandings, whether written or oral, between or among the parties. Except as expressly provided herein, neither this Agreement nor any term hereof may be amended except pursuant to a written instrument executed by Company and the Majority in Interest, and no provision hereof may be waived other than by a written instrument signed by the party against whom enforcement of any such waiver is sought. The Secured Parties shall not, by any act, any failure to act or any delay in acting be deemed to have (i) waived any right or remedy under this Agreement, or (ii) acquiesced in any Event of Default or in any breach of any of the terms and conditions of this Agreement. No failure to exercise, nor any delay in exercising, any right, power or privilege of the Secured Parties under this Agreement shall operate as a waiver of any such right, power or privilege. No single or partial exercise of any right, power or privilege under this Agreement shall preclude any other or further exercise of any other right, power or privilege. A waiver by a Secured Party of any right or remedy under this Agreement on any one occasion shall not be construed as a bar to any right or remedy that such Secured Party would otherwise have on any future occasion.

Section 8.8 Multiple Counterparts. This Agreement has been executed in a number of identical counterparts, each of which shall be deemed an original for all purposes and all of which constitute, collectively, one agreement; but, in making proof of this Agreement, it shall not be necessary to produce or account for more than one such counterpart.

Section 8.10 Cumulative Remedies. The rights and remedies provided in this Agreement are cumulative, may be exercised singly or concurrently, and are not exclusive of any other rights or remedies provided by law.

Section 8.11 Waivers. The Company acknowledges that the Obligations arose out of a commercial transaction and hereby knowingly waives any right to require the Secured Parties to (i) proceed against any person or entity, (ii) proceed against any other collateral under any other agreement, (iii) pursue any other remedy available to the Secured Parties, or (iv) make presentment, demand, dishonor, notice of dishonor, acceleration and/or notice of non-payment.

Section 8.12 Release. No transfer or renewal, extension, assignment or termination of this Agreement or of any instrument or document executed and delivered by the Company to the Secured Parties, nor additional advances made by the Secured Parties to the Company, nor the taking of further security, nor the retaking or re-delivery of the Collateral by the Secured Parties nor any other act of the Secured Parties shall release the Company from any Obligation, except a release or discharge executed in writing by the Majority in Interest or Collateral Agent with respect to such Obligation or upon full

payment and satisfaction of all Obligations and termination of the Debentures. At such time the Obligations have been satisfied in full, the Majority in Interest or Collateral Agent (if one had been appointed) shall execute and deliver to the Company all assignments and other instruments as may be reasonably necessary or proper to terminate the Secured Parties’ security interest in the Collateral, subject to any disposition of the Collateral that may have been made by or on behalf of the Secured Parties pursuant to this Agreement. For the purpose of this Agreement, the Obligations shall be deemed to continue if the Company enters into any bankruptcy or similar proceeding at a time when any amount paid to the Secured Parties could be ordered to be repaid as a preference or pursuant to a similar theory, and shall continue until it is finally determined that no such repayment can be ordered.
