3. Representations, Warranties, Covenants and Agreements of the Debtor. The Debtor represents and warrants to, and covenant and agree with, each of the Secured Parties as follows:

(a) The Debtor has the requisite corporate power and authority to enter into this Agreement and to otherwise carry out its obligations thereunder. The execution, delivery and performance by the Debtor of this Agreement and the filings contemplated therein have been duly authorized by all necessary action on the part of the Debtor and no further action is required by the Debtor.

(b) Except for the Security Interest and subject to the EKI License Agreement, the Debtor is the sole owner of its rights in the Collateral, free and clear of any liens, security interests or encumbrances, and is fully authorized to grant the Security Interest in and to pledge the Collateral. There is not on file in any governmental or regulatory authority, agency or recording office an effective financing statement, security agreement or transfer or any notice of any of the foregoing (other than those that have been filed in favor of the Secured Parties pursuant to this Agreement) covering or affecting any of the Collateral. So long as this Agreement shall be in effect, the Debtor shall not execute and shall not authorize the filing of in any such office or agency any such financing statement or other document or instrument (except to the extent filed or recorded in favor of the Secured Parties pursuant to the terms of this Agreement) without the consent of the Secured Parties.

(c) To the knowledge of the Debtor, no part of the IP Property has been judged invalid or unenforceable. Debtor is in full compliance with the EKI License Agreement and all sublicense agreements related thereto. No written claim has been received, and Debtor has no knowledge of any claim that (1) any of the IP Property or the Debtor’s use of any Collateral violates the rights of any third party, or (2) Debtor is in breach of the EKI License Agreement or any sublicense agreement with respect thereto. Subject to the EKI License Agreement, there has been no adverse decision of which the Debtor is aware as to the Debtor’s exclusive (or nonexclusive, as the case may be) rights to use the Collateral in any jurisdiction, and, to the knowledge of the Debtor there is no proceeding involving said rights pending or threatened before any court, judicial body, administrative or regulatory agency, arbitrator or other governmental authority.

(d) The Debtor shall at all times maintain its books of account and records relating to the Collateral at its principal place of business and may not relocate such books of account and records unless it delivers to each of the Secured Parties at least 30 days prior to such relocation (i) written notice of such relocation and the new location thereof (which must be within the United States) and (ii) evidence that appropriate financing statements and other necessary documents have been filed and recorded and other steps have been taken to perfect the Security Interest to create in favor of each of the Secured Parties a valid, perfected and continuing first priority lien in the Collateral.

(e) This Agreement creates in favor of each of the Secured Parties a valid security interest in the Collateral, securing the payment and satisfaction of the Obligations, and, upon making the filings described in the immediately following sentence, a perfected first priority security interest in such Collateral that is senior to all hereinafter created security interests. Except for: the filing of financing statements on Form UCC-1 under the UCC with the jurisdictions indicated in Schedule A, attached hereto, no authorization or approval of or filing with or notice to any governmental authority or regulatory body is required either: (i) for the grant by the Debtor of, or the effectiveness of, the Security Interest granted hereby or for the execution, delivery and performance of this Agreement by the Debtor or (ii) for the perfection of or exercise by the Secured Parties of its rights and remedies hereunder.

(f) On the date of execution of this Agreement, the Debtor authorizes each Secured Party to: (i) file one or more financing statements under the UCC with respect to the Security Interest for filing with the jurisdictions indicated on Schedule A, attached hereto and

in such other jurisdictions as the Secured Parties deem necessary and (ii) one or more executed recordation sheets relating to the filing and recording of this Agreement with the United States Patent and Trademark Office.

(g) The execution, delivery and performance of this Agreement does not conflict with or cause a breach or default, or an event that with or without the passage of time or notice, shall constitute a breach or default, under any agreement to which the Debtor is a party or by which the Debtor is bound. No consent (including, without limitation, from stock holders or creditors of the Debtor) is required for the Debtor to enter into and perform its obligations hereunder.

(h) The Debtor shall at all times maintain the liens and Security Interest provided for hereunder as valid and perfected first priority liens and security interests in the Collateral in favor of each of the Secured Parties and insure that such liens and Security Interests are and remain senior to all not existing and hereafter created security interests and liens. The Debtor hereby agrees to defend the same against any and all persons. The Debtor shall safeguard and protect all Collateral for the account of each of the Secured Parties. At the request of the Agent and/or Secured Parties, the Debtor will sign and deliver to the Secured Parties at any time or from time to time one or more financing statements pursuant to the UCC in form reasonably satisfactory to the Secured Parties and will pay the cost of filing the same in all public offices wherever filing is, or is deemed by the Secured Parties to be, necessary or desirable to effect the rights and obligations provided for herein. Without limiting the generality of the foregoing, the Debtor shall pay all fees, taxes and other amounts necessary to maintain the Security Interest hereunder, and the Debtor shall obtain and furnish to the Secured Parties from time to time, upon demand, such releases and /or subordinations of claims and liens which may be required to maintain the priority of the Security Interest hereunder.

(i) Except for sublicenses granted by the Debtor in respect of the IP Property pursuant to the EKI License Agreement, the Debtor will not transfer, pledge, hypothecate, encumber, license, sell or otherwise dispose of any IP Property, nor will it exercise any right of termination under the EKI License Agreement, without the prior written consent of the Secured Parties.

(j) The Debtor shall, within ten (10) days of obtaining knowledge thereof, advise the Agent, in sufficient detail, of any substantial change in the Collateral, and of the occurrence of any event which would have a material adverse effect on the value of the Collateral or on the Secured Parties’ security interest therein.

(k) The Debtor shall permit the Secured Parties and its representatives and agents upon reasonable prior notice to inspect the Collateral at any time during normal business hours, and to make copies of records pertaining to the Collateral as may be reasonably requested by the Secured Parties from time to time.

(l) The Debtor is not in breach of the EKI License Agreement, and it will take all actions necessary to ensure that it does not breach the EKI License Agreement in the future. The Debtor shall promptly notify the Agent in sufficient detail upon becoming aware of any attachment, garnishment, execution or other legal process levied against any Collateral and

of any other information received by the Debtor that reasonably would be expected to substantially affect the value of the Collateral, the Security Interest or the rights and remedies of the Secured Parties hereunder.

(m) The Debtor shall not use or permit any Collateral to be used unlawfully or in violation of any provision of this Agreement, the EKI License Agreement, or any applicable statute, regulation or ordinance or any policy of insurance covering the Collateral where violation is reasonably likely to have a material adverse effect on the Secured Parties’ rights in the Collateral or Secured Parties’ ability to foreclose on the Collateral.

(n) The Debtor shall not grant to any person or entity any rights or interest in or to any of the Collateral that are senior to, or pari passu with, the Secured Parties.

(o) The Debtor shall notify the Agent of any change in the Debtor’s name, identity, chief place of business, chief executive office or residence within 5 days of such change.

(b) Any representation or warranty of the Debtor in this Agreement shall prove to have been incorrect in any material respect when made.

5. Duty To Hold In Trust. Upon the occurrence and during the continuation of any Event of Default, the Debtor shall, upon receipt by it of any revenue, income or other sums subject to the Security Interest, or of any check, draft, note, trade acceptance or other instrument evidencing an obligation to pay any such sum, hold the same in trust for the Secured Parties and shall forthwith endorse and transfer any such sums or instruments, or both, to the Secured Parties for application to the satisfaction of the Obligations.

6. Rights and Remedies Upon Default. Upon the occurrence and during the continuation of any Event of Default, the Agent (on behalf of, and for the benefit of itself and each Secured Party) shall have the right to exercise all of the remedies conferred hereunder, under the Debentures, and the Agent and the Secured Parties shall have all the rights and remedies of a secured party under the UCC. Without limitation, the Secured Parties shall have the following rights and powers upon and during the continuance of an Event of Default:

(a) The Agent shall have the right to take possession of all tangible manifestations or embodiments of the Collateral and, for that purpose, enter, with the aid and assistance of any person, any premises where the Collateral, or any part thereof, is or may be placed and remove the same, and the Debtor shall assemble the Collateral and make it available to the Agent at places which the Agent shall reasonably select, whether at the Debtor’s premises or elsewhere.

(b) The Agent shall have the right to operate the business of the Debtor using the Collateral and shall have the right to assign, sell, or otherwise dispose of and deliver all or any part of the Collateral, at public or private sale or otherwise, either with or without special conditions or stipulations, for cash or on credit or for future delivery, in such parcel or parcels and at such time or times and at such place or places, and upon such terms and conditions as the Agent may deem commercially reasonable, all without (except as shall be required by applicable statute and cannot be waived) advertisement or demand upon or notice to the Debtor or right of redemption of the Debtor, which are hereby expressly waived. Upon each such sale, assignment or other transfer of Collateral, the Agent may, unless prohibited by applicable law which cannot be waived, purchase all or any part of the Collateral being sold, free from and discharged of all trusts, claims, right of redemption and equities of the Debtor, which are hereby waived and released.

(c) The Agent may sublicense or, to the same extent the Debtor is permitted by law and contract to do so, whether or an exclusive or non-exclusive basis, any of the Collateral throughout the world for such period, on such conditions and in such manner as the Secured Parties shall, in its reasonable discretion, determine.

(d) The Agent may (without assuming any obligations or liabilities thereunder), at any time, enforce (and shall have the exclusive right to enforce) against licensee or sublicensee all rights and remedies of the Debtor in, to and under any license agreement with respect to such Collateral, and take or refrain from taking any action thereunder.

(e) The Agent may, in order to implement the assignment, license, sale or other disposition of any of the Collateral pursuant to this Section, pursuant to the authority provided for in Section 11, execute and deliver on behalf of the Debtor one or more instruments of assignment of the Collateral in form suitable for filing, recording or registration in any jurisdictions as the Secured Parties may determine advisable.

(f) In the event that any Secured Party shall recover from the Debtor or the Collateral more than its pro rata share of the Obligations owed to all Secured Parties hereunder, whether by agreement, understanding or arrangement with the Debtor or any other Person, set off or other means, such Secured Party shall immediately deliver or pay over to the other Secured Parties their pro rata portion of any such recovery in the form received.

(g) Agent may, at any time or times that an Event of Default exists or has occurred and is continuing: (i) notify any or all accounts of the Debtor (“Accounts”) that such Accounts have been assigned to Secured Parties and that Secured Parties have a security interest therein and Agent may direct any or all accounts Debtor to make payment of accounts directly to Secured Parties, (ii) extend the time of payment of, compromise, settle or adjust for cash, credit, return of merchandise or otherwise, and upon any terms or conditions, any and all Accounts or other obligations included in the Collateral and thereby discharge or release the account debtor or any other party or parties in any way liable for payment thereof without affecting any of the Obligations, (iii) demand, collect or enforce payment of any Accounts or such other obligations, but without any duty to do so, and Agent shall not be liable for its failure to collect or enforce the payment thereof nor for the negligence of its agents or attorneys with respect thereto and (iv) take whatever other action Agent may deem necessary or desirable for the protection of its

interests. At any time that an Event of Default exists or has occurred and is continuing, at Agent’s request, all invoices and statements sent to any account debtor shall state that the Accounts and such other obligations have been assigned to Secured Parties and are payable directly and only to Secured Parties and the Debtor shall deliver to Agent such originals of documents evidencing the sale and delivery of goods or the performance of services giving rise to any Accounts as Agent may require.

7. Applications of Proceeds; Expenses. (a) The proceeds of any such sale, sublicense or other disposition of the Collateral hereunder shall be applied first, to the expenses of retaking, holding, storing, processing and preparing for sale, selling, and the like (including, without limitation, any taxes, fees and other costs incurred in connection therewith) of the Collateral, to the reasonable attorneys’ fees and expenses incurred by the Agent and/or Secured Parties in enforcing its rights hereunder and in connection with collecting, storing and disposing of the Collateral, and then to satisfaction of the Obligations, and to the payment of any other amounts required by applicable law, after which the Secured Parties shall pay to the Debtor any surplus proceeds. If, upon the sale, license or other disposition of the Collateral, the proceeds thereof are insufficient to pay all amounts to which the Secured Parties are legally entitled, the Debtor will be liable for the deficiency, together with interest thereon, at the rate of 12% per annum or the lesser amount permitted by applicable law (the “Default Rate”), and the reasonable fees of any attorneys employed by the Agent and/or Secured Parties to collect such deficiency. To the extent permitted by applicable law, the Debtor waives all claims, damages and demands against the Secured Parties arising out of the repossession, removal, retention or sale of the Collateral, unless due to the gross negligence or willful misconduct of the Agent and/or Secured Parties.

(b) The Debtor agree to pay all out-of-pocket fees, costs and expenses reasonably incurred in connection with any filing required hereunder, including, without limitation, any financing statements, continuation statements, partial releases and/or termination statements related thereto or any expenses of any searches reasonably required by the Agent. The Debtor shall also pay all other claims and charges which in the reasonable opinion of the Agent and/or Secured Parties would reasonably be expected to prejudice, imperil or otherwise affect the Collateral or the Security Interest therein. The Debtor will also, upon demand, pay to the Agent and/or Secured Parties the amount of any and all reasonable expenses, including the reasonable fees and expenses of its counsel and of any experts and agents, which the Agent and/or Secured Parties may incur in connection with (i) the enforcement of this Agreement, (ii) the custody or preservation of, or the sale of, collection from, or other realization upon, any of the Collateral, or (iii) the exercise or enforcement of any of the rights of the Secured Parties under the Debentures. Until so paid, any fees payable hereunder shall be added to the principal amount of the Debentures and shall bear interest at the Default Rate.

8. Responsibility for Collateral. The Debtor assumes all liabilities and responsibility in connection with all Collateral, and the obligations of the Debtor hereunder or under the Debentures shall in no way be affected or diminished by reason of the loss, destruction, damage or theft of any of the Collateral or its unenforceability or unavailability for any reason.

9. Security Interest Absolute. All rights of the Secured Parties and all Obligations of the Debtor hereunder, shall be absolute and unconditional, irrespective of: (a) any lack of validity

or enforceability of this Agreement, the Debentures or any agreement entered into in connection with the foregoing, or any portion hereof or thereof; (b) any change in the time, manner or place of payment or performance of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure from the Debentures or any other agreement entered into in connection with the foregoing; (c) any exchange, release or nonperfection of any of the Collateral, or any release or amendment or waiver of or consent to departure from any other collateral for, or any guaranty, or any other security, for all or any of the Obligations; (d) any action by the Secured Parties to obtain, adjust, settle and cancel in its sole discretion any insurance claims or matters made or arising in connection with the Collateral; or (e) any other circumstance which might otherwise constitute any legal or equitable defense available to the Debtor, or a discharge of all or any part of the Security Interest granted hereby. Until the Obligations shall have been paid and performed in full, the rights of the Secured Parties shall continue even if the Obligations are barred for any reason, including, without limitation, the running of the statute of limitations or bankruptcy. The Debtor expressly waives presentment, protest, notice of protest, demand, notice of nonpayment and demand for performance. In the event that at any time any transfer of any Collateral or any payment received by the Secured Parties hereunder shall be deemed by final order of a court of competent jurisdiction to have been a voidable preference or fraudulent conveyance under the bankruptcy or insolvency laws of the United States, or shall be deemed to be otherwise due to any party other than the Secured Parties, then, in any such event, the Debtor’s obligations hereunder shall survive cancellation of this Agreement, and shall not be discharged or satisfied by any prior payment thereof and/or cancellation of this Agreement, but shall remain a valid and binding obligation enforceable in accordance with the terms and provisions hereof. The Debtor waives all right to require the Secured Parties to proceed against any other person or to apply any Collateral which the Secured Parties may hold at any time, or to marshal assets, or to pursue any other remedy. The Debtor waives any defense arising by reason of the application of the statute of limitations to any obligation secured hereby.

10. Term of Agreement. This Agreement and the Security Interest shall terminate on the date on which all payments under the Debentures have been made in full or otherwise converted pursuant to the terms thereof and all other Obligations have been paid or discharged in full. Upon such termination, the Secured Parties, at the request and at the expense of the Debtor, will join in executing any termination statement with respect to any financing statement executed and filed pursuant to this Agreement.

11. Power of Attorney; Further Assurances. (a) The Debtor authorizes the Secured Parties, and does hereby make, constitute and appoint it, and its respective officers, agents, successors or assigns with full power of substitution, as the Debtor’s true and lawful attorney-in-fact, with power, in its own name or in the name of the Debtor, to, after the occurrence and during the continuance of an Event of Default, (i) endorse any notes, checks, drafts, money orders, or other instruments of payment (including payments payable under or in respect of any policy of insurance) in respect of the Collateral that may come into possession of the Secured Parties; (ii) to sign and endorse any UCC financing statement or any invoice, freight or express xxxx, xxxx of lading, storage or warehouse receipts, drafts against Debtor, assignments, verifications and notices in connection with accounts, and other documents relating to the Collateral; (iii) to pay or discharge taxes, liens, security interests or other encumbrances at any time levied or placed on or threatened against the Collateral; (iv) to demand, collect, receipt for,

compromise, settle and xxx for monies due in respect of the Collateral; and (v) generally, to do, at the option of the Secured Parties, and at the Debtor’s expense, at any time, or from time to time, all acts and things which the Secured Parties deem necessary to protect, preserve and realize upon the Collateral and the Security Interest granted therein, including, without limitation, executing any documents necessary to evidence the assignment of the Debtor’s rights and obligations under the EKI License Agreement to the Secured Parties, in order to effect the intent of this Agreement and the Debentures, all as fully and effectually as the Debtor might or could do; and the Debtor hereby ratifies all that said attorney shall lawfully do or cause to be done by virtue hereof. This power of attorney is coupled with an interest and shall be irrevocable for the term of this Agreement and thereafter as long as any of the Obligations shall be outstanding.

(b) On a continuing basis, the Debtor will make, execute, acknowledge, deliver, file and record, as the case may be, with the proper filing and recording places in any jurisdiction, including, without limitation, the jurisdictions indicated on Schedule A, attached hereto, all such instruments, including appropriate financing and continuation statements and collateral agreements and filings with the United States Patent and Trademark Office, and take all such action as may reasonably be deemed necessary or advisable, or as reasonably requested by the Secured Parties, to perfect the Security Interest granted hereunder and otherwise to carry out the intent and purposes of this Agreement, or for assuring and confirming to the Secured Parties the grant or perfection of a first priority security interest in all the Collateral.

(c) The Debtor hereby irrevocably appoints the Secured Parties as the Debtor’s attorney-in-fact, with full authority in the place and stead of the Debtor and in the name of the Debtor, from time to time in the Secured Parties’ discretion, to take any action and to execute any instrument which the Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including (without limitation) to file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral.

Debentures, including the reimbursement of the Agent for all out-of-pocket expenses (including attorneys’ fees) incurred by the Agent hereunder or in connection herewith or in enforcing the Obligations of the Debtor under this Agreement or the Debentures, in all cases as to which the Agent is not reimbursed by the Debtor; provided that no Secured Party shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements determined by a court of competent jurisdiction in a final proceeding to have resulted solely from the Agent’s gross negligence or willful misconduct. The Agent shall not be required to take any action hereunder or under the Debentures, or to prosecute or defend any suit in respect of this Agreement or under the Debentures, unless the Agent is indemnified to its reasonable satisfaction by the Secured Parties against loss, costs, liability and expense.

(b) Exculpation.

The Agent shall be entitled to rely upon advice of counsel concerning legal matters and upon any notice, consent, certificate, statement or writing which it believes to be genuine and to have presented by a proper person.

(c) Obligations Held by the Agent. The Agent shall have the same rights and powers with respect to any Debentures held by it or any of its affiliates, as any Secured Party and may exercise the same as if it were not the Agent. Each of the Debtor and each Secured Party hereby waives, and each successor to any Secured Party shall be deemed to waive, any right to disqualify any Secured Party from serving as the Agent or any claim against that Secured Party for serving as Agent.

(d) Copies, etc. The Agent shall give prompt notice to each Secured Party of each notice or request required or permitted to be given to the Agent by the Debtor pursuant to the terms of this Agreement. The Agent will distribute to each Secured Party each instrument and other agreement received for its account and copies of all other communications received by the Agent from a Debtor for distribution to the Secured Party by the Agent in accordance with the terms of this Agreement.
