SECTION 3.03.Illegality.  If the Lender determines at any time that any Law or treaty or any change therein or in the interpretation or application thereof makes or will make it unlawful for the Lender to fulfill its commitment in accordance with Section 2.01, to maintain the Loans (including the aggregate principal amount, if any, added to the Loans pursuant to Sections 4.01(a) and 4.01(b)) or to claim or receive any amount payable to it hereunder, the Lender shall give Notice of that determination to Borrower, whereupon the obligations of the Lender hereunder shall terminate.  If any such Notice is given after the disbursement of the Loans, Borrower shall prepay the Loans in full on the Interest Payment Date following the date the Notice is given; provided, however, that if the Lender certifies to Borrower that earlier prepayment is necessary in order to enable the Lender to comply with the relevant Law, treaty or change and specifies an earlier date for the prepayment, Borrower shall make the prepayment on the date so specified.  Prepayment pursuant to this Section 3.03 shall be made together with interest accrued and unpaid on the Loans to the date of prepayment and all other amounts then payable to the Lender hereunder.  Each Notice delivered pursuant to this Section 3.03 shall be effective when sent.

SECTION 4.01.Interest Rate.

(a)From the Closing Date to the Existing Loan Prepayment Date, the Tranche A Loan shall bear interest at a rate equal to 13% per annum, which shall be paid in kind, on a quarterly basis, and on each Interest Payment Date occurring during each such quarter, the Lender shall be deemed to have made an additional loan in a principal amount equal to the aggregate amount of interest required to be paid on the outstanding Loans on such Interest Payment Date.  Each such deemed Loan shall (A) be deemed to be a Loan for all purposes under this Agreement and (B) accrue interest in accordance with this Section 4.01.

SECTION 5.05.Loans Treated As Indebtedness.  The Parties agree to treat the Loans as indebtedness for borrowed money of Borrower for all tax purposes.  The Parties agree not to take any position that is inconsistent with the provisions of this Section 5.05 on any tax return or in any audit or other administrative or judicial proceeding unless (i) the other Party has consented to such actions, or (ii) the Party that contemplates taking such an inconsistent position has been advised by nationally recognized tax counsel in writing that it is more likely than not that (x) there is no “reasonable basis” (within the meaning of Treasury Regulation Section 1.6662-3(b)(3)) for the position specified in this Section 5.05 or (y) taking such a position would otherwise subject the Party to penalties under the Code.

(a)Borrower agrees to defend (subject to Indemnitees’ selection of counsel), indemnify, pay and hold harmless, the Lender and its Affiliates and their respective officers, partners, directors, trustees, employees and agents (each, an “Indemnitee”), from and against any and all Indemnified Liabilities, in all cases, whether or not caused by or arising, in whole or in part, out of the comparative, contributory or sole negligence of such Indemnitee; provided Borrower shall not have any obligation to any Indemnitee hereunder with respect to any Indemnified Liabilities to the extent such Indemnified Liabilities arise from the gross negligence or willful misconduct of such Indemnitee.  To the extent that the undertakings to defend, indemnify, pay and hold harmless set forth in this Section 12.03 may be unenforceable in whole or in part because they are violative of any law or public policy, Borrower shall contribute the maximum portion that it is permitted to pay and satisfy under applicable law to the payment and satisfaction of all Indemnified Liabilities incurred by Indemnitees or any of them.

(b)To the extent permitted by applicable law, no Party shall assert, and each Party hereby waives, any claim against each other Party and such Party’s Affiliates, directors, employees, attorneys or agents, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) (whether or not the claim therefor is based on contract, tort or duty imposed by any applicable legal requirement) arising out of, in connection with, as a result of, or in any way related to, this Agreement or any Loan Document or any agreement or instrument contemplated hereby or thereby or referred to herein or therein, the transactions contemplated hereby or thereby, the Loans or the use of the proceeds thereof or any act or omission or event occurring in connection therewith, and each Party hereby waives, releases and agrees not to sue upon any such claim or any such damages, whether or not accrued and whether or not known or suspected to exist in its favor.

SECTION 12.04.Assumption of Defense; Settlements.  If the Lender is entitled to indemnification under this Article XII with respect to any action or proceeding brought by a third party that is also brought against Borrower, Borrower shall be entitled to assume the defense of any such action or proceeding with counsel reasonably satisfactory to the Lender.  Upon assumption by Borrower of the defense of any such action or proceeding, Borrower shall have the right to participate in such action or proceeding and to retain its own counsel but Borrower shall not be liable for any legal expenses of other counsel subsequently incurred by the Lender in connection with the defense thereof unless (i) Borrower has otherwise agreed to pay such fees and expenses, (ii) Borrower shall have failed to employ counsel reasonably satisfactory to the Lender in a timely manner or (iii) the Lender shall have been advised by counsel that there are actual or potential conflicting interests between Borrower and the Lender, including situations in which there are one or more legal defenses available to the Lender that are different from or additional to those available to Borrower; provided, however, that Borrower shall not, in connection with any one such action or proceeding or separate but substantially similar actions or proceedings arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for the Lender, except to the extent that local counsel, in addition to its regular counsel, is required in order to effectively defend against such action or proceeding.  Borrower shall not consent to the terms of any compromise or settlement of any action defended by Borrower in accordance with the foregoing without the prior written consent of the Lender unless such compromise or settlement (x) includes an unconditional release of the Lender from all liability arising out of such action and (y) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of the Lender.  Borrower shall not be required to indemnify the Lender for any amount paid or payable by the Lender in the settlement of any action, proceeding or investigation without the written consent of Borrower, which consent shall not be unreasonably withheld.

SUBORDINATION

SECTION 14.01.Obligations Subordinated to Indebtedness Under the Existing Loan Agreement.  Borrower covenants and agrees, and the Lender by its acceptance hereof likewise covenants and agrees, that all Obligations shall be issued subject to the provisions of this Article XIV; and each Person holding any Obligations, whether upon original issue or upon transfer, assignment or exchange thereof, accepts and agrees that all payments of the principal of and interest on the Obligations by Borrower shall, to the extent and in the manner set forth in this Article XIV be subordinated and junior in right of payment to the prior payment in full in cash of the Existing Loan.

SECTION 14.02.No Payment on Obligations in Certain Circumstances; Payment Held in Trust.

(a)No Payments in Certain Circumstances.  No direct or indirect payment by or on behalf of Borrower of principal of or interest on the Loans, whether pursuant to the terms of the Obligations, upon acceleration, or otherwise, shall be made if, at the time of such payment, there exists a default in the payment of all or any portion of the obligations under the Existing Loan Agreement, whether at maturity, on account of mandatory redemption or prepayment or acceleration, and such default shall not have been cured or waived or the benefits of this sentence waived by or on behalf of lender under the Existing Loan Agreement.

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote such omission.

-62-

(b)Payments Held in Trust.  In the event that, notwithstanding the foregoing, any payment shall be received by the Lender when such payment is prohibited by Section 14.02(a), such payment shall be held in trust for the benefit of, and shall be paid over or delivered to, the lender under the Existing Loan Agreement, but only to the extent that, upon notice from the Lender to the lender under the Existing Loan Agreement that such prohibited payment has been made, such lender notifies the Lender in writing of the amounts then due and owing on Existing Loan, if any, and only the amounts specified in such notice to the Lender shall be paid to such lender.

SECTION 14.03.Payment Over of Proceeds upon Dissolution, Etc.

(a)Payment Over.  Upon any payment or distribution of assets or securities of Borrower of any kind or character, whether in cash, property or securities, upon any dissolution or winding-up or liquidation or reorganization of Borrower, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, the Existing Loan shall first be paid in full in cash before the Lender shall be entitled to receive any payment by Borrower of the principal of or interest on the Obligations, or any payment by Borrower to acquire any of the Obligations for cash, property or securities, or any distribution with respect to the Obligations of any cash, property or securities.  Before any payment may be made by, or on behalf of, Borrower of the principal of or interest on the Obligations upon any such dissolution or winding-up or liquidation or reorganization, any payment or distribution of assets or securities of Borrower of any kind or character, whether in cash, property or securities, to which the Lender would be entitled, but for the subordination provisions of this Agreement, shall be made by Borrower or by any receiver, trustee in bankruptcy, liquidation trustee, agent or other Person making such payment or distribution, directly to the lender under the Existing Loan Agreement, to the extent necessary to pay the Existing Loan in full in cash after giving effect to any prior or concurrent payment, distribution or provision therefor to or for the lender under the Existing Loan Agreement.

(b)Payments Held in Trust.  In the event that, notwithstanding the foregoing provision prohibiting such payment or distribution, any payment or distribution of assets or securities of Borrower of any kind or character, whether in cash, property or securities, shall be received by the Lender at a time when such payment or distribution is prohibited by Section 14.03(a) and before all obligations in respect of Existing Loan are paid in full in cash, or payment provided for, such payment or distribution shall be received and held in trust for the benefit of, and shall be paid over or delivered to, the lender under the Existing Loan Agreement, for application to the payment of Existing Loan remaining unpaid until the Existing Loan has been paid in full in cash after giving effect to any prior or concurrent payment, distribution or provision therefor to or for the lender under the Existing Loan Agreement.

SECTION 14.04.Subrogation.  Upon the payment in full in cash of the Existing Loan, or provision for payment, the Lender shall be subrogated to the rights of the lender under the Existing Loan Agreement to receive payments or distributions of cash, property or securities of Borrower made on the Existing Loan until the principal of and interest on the Obligations shall be paid in full in cash; and, for the purposes of such subrogation, no payments or distributions to the lender under the Existing Loan Agreement of any cash, property or securities to which the Lender would be entitled except for the provisions of this Article XIV, and no payment over pursuant to the provisions of this Article XIV to the lender under the Existing Loan Agreement by the Lender shall, as between Borrower, its creditors other than the lender under the Existing Loan Agreement, and the Lender, be deemed to be a payment by Borrower to or on account of the Existing Loan.  It is understood that the provisions of this Article XIV are and are intended solely for the purpose of defining the relative rights of the Lender, on the one hand, and the lender under the Existing Loan Agreement, on the other hand.

-63-

(a)If any payment or distribution to which the Lender would otherwise have been entitled but for the provisions of this Article XIV shall have been applied, pursuant to the provisions of this Article XIV, to the payment of all amounts payable under Existing Loan, then and in such case, the Lender shall be entitled to receive from the lender under the Existing Loan Agreement any payments or distributions received by such lender in excess of the amount required to make payment in full, or provision for payment, of the Existing Loan.

SECTION 14.05.Obligations of Borrower Unconditional.  Nothing contained in this Article XIV or elsewhere in this Agreement is intended to or shall impair, as among Borrower and the Lender, the obligation of Borrower, which is absolute and unconditional, to pay to the Lender the principal of and interest on the Obligations as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Lender and creditors of Borrower other than the lender under the Existing Loan Agreement, nor shall anything herein or therein prevent the Lender from exercising all remedies otherwise permitted by applicable Law upon Default under this Agreement, subject to the rights, if any, under this Article XIV of the lender under the Existing Loan Agreement in respect of cash, property or securities of Borrower received upon the exercise of any such remedy.

Without limiting the generality of the foregoing, nothing contained in this Article XIV shall restrict the right of the Lender to take any action to declare the Obligations to be due and payable prior to the Tranche A Maturity Date or the Maturity Date, as the case may be, or to pursue any rights or remedies hereunder; provided, however, that Existing Loan then due and payable shall first be paid in full before the Lender is entitled to receive any direct or indirect payment from Borrower of principal of or interest on the Obligations.

SECTION 14.06.Reliance on Judicial Order or Certificate of Liquidating Agent.  Upon any payment or distribution of assets or securities referred to in this Article XIV, the Lender shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or upon a certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent or other person making such payment or distribution, delivered to the Lender for the purpose of ascertaining the Persons entitled to participate in such distribution, the lender under the Existing Loan Agreement and other indebtedness of Borrower, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XIV.

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote such omission.

SECTION 14.07.Lender’s Relation to Senior Indebtedness.  The Lender shall be entitled to all the rights set forth in this Article XIV with respect to any portion of the Existing Loan which may at any time be held by it in its individual or any other capacity to the same extent as the lender under the Existing Loan Agreement, and nothing in this Agreement shall deprive the Lender of any of its rights thereunder.

With respect to the lender under the Existing Loan Agreement, the Lender undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article XIV, and no implied covenants or obligations with respect to such lender shall be read into this Agreement against the Lender.  The Lender shall not be deemed to owe any fiduciary duty to the lender under the Existing Loan Agreement (except to the extent provided in Section 14.03(b)).  The Lender shall not be liable to such lender if the Lender shall in good faith mistakenly pay over or distribute to Borrower or to any other Person cash, property or securities to which such lender shall be entitled by virtue of this Article XIV or otherwise.

SECTION 14.08.This Section Not To Prevent Events of Default.  The failure to make a payment on account of principal of or interest on the Obligations by reason of any provision of this Article XIV shall not be construed as preventing the occurrence of an Event of Default.

(b)           (1) Only Lender shall be entitled to give Account Instructions directing the disposition, transfer, withdrawal, disbursement, investment or redemption of any Deposit Funds in or credited to the Lender Concentration Account, and the Financial Institution shall comply with such Account Instructions from Lender from time to time.  The parties acknowledge that the Lender Concentration Account is the unencumbered property of the Lender.

Section 5.          Financial Institution’s Obligations with respect to the Deposit Accounts.

(a)           The Financial Institution agrees to maintain each Deposit Account separately, in accordance with the terms of this Agreement and agrees not to commingle the Deposit Funds in or credited to, or designated for deposit in, any Deposit Account with any other Deposit Funds held on behalf of Company, Lender or any other person or entity.  The Financial Institution shall not apply any Deposit Funds received in the Deposit Accounts and not to make disbursements from or debits to the Deposit Accounts other than in accordance with this Agreement.  In the event there are multiple Lenders, the Financial Institution shall distribute Deposit Funds in the Lender Concentration Account on a pro rata basis to the Lenders according to their proportionate interests in the Loan as required by Section 13.01(d) of the Loan Agreement and in accordance with the applicable Register Notice, if any, delivered by Company pursuant to Section 5.06(a) of the Loan Agreement.  Prior to making any distributions to a new Lender, the Financial Institution will require such Lender to deliver to the Lockbox Escrow Agent and Financial Institution a W-8 or W-9 Internal Revenue Service form or any other similar form issued by the relevant taxing authority duly executed by it.

(d)           The Financial Institution shall redeposit with advice any item returned for any reason.  If any item is returned a second time, the Financial Institution will charge the amount of such item against the Lockbox Account if the same contains sufficient funds to pay the amount of the returned item.  If the balance in the Lockbox Account is not sufficient to pay the amount of the returned item, the Financial Institution shall notify Company and Lender.  Company agrees to reimburse the Financial Institution for the same promptly after such notification.  The Financial Institution shall also notify Company and Lender of its current standard charges for returned items and Company agrees to pay the Financial Institution such charges promptly after such notification.  The Financial Institution shall return the item along with the debit advice to Company, with a copy to Lender.  The Financial Institution is granted the further right to debit from any Deposit Account any amounts deposited therein in error or as necessary to correct processing errors.

(e)           Each week that the Financial Institution receives any Deposit Funds in any Deposit Account, the Financial Institution shall notify Company and Lender in writing that it has received such Deposit Funds into such account or accounts, and the Financial Institution shall set forth in such writing (i) the names of the accounts into which such Deposit Funds were received, if such payments have been received, (ii) the date of receipt of such Deposit Funds, (iii) the amount of such receipt and (iv) the name of the payor.

(b)           Upon the determination by Lender or, if the Lockbox Calculation Agent at such time is not Company or an Affiliate thereof, Company (in each case, whether Lender or Company, acting reasonably and in good faith), that a Termination Event has occurred (or, where Company is acting as Lockbox Calculation Agent, an Event of Default has occurred), Lender or Company, as the case may be, shall have the right to remove the Lockbox Calculation Agent by providing written notice of such determination to the other parties hereto; provided that, at Lender’s option, the Lockbox Calculation Agent may immediately be suspended pending the resolution of any dispute regarding the provision of such a notice as described in this Section 7(b).  In the event such a determination is made, Lender or Company, as the case may be, may dispute such determination by providing written notice to the other party within ten (10) Business Days of receipt of the removal notice.  If no such dispute notice is so provided, the Lockbox Calculation Agent shall be removed and a successor Lockbox Calculation Agent shall be selected in accordance with Section 7(c).  If such a dispute notice is timely provided, then the relevant parties shall first attempt to reach an amicable settlement through mutual consultations and negotiations.  If the parties are unable to reach an amicable settlement within ten (10) Business Days from the date on which the dispute was first notified in writing, then any party shall be entitled to submit the dispute to litigation proceedings in accordance with the terms hereof.  Pending the resolution of any such dispute, (unless the Lockbox Calculation Agent has been suspended as described above) the party then serving as Lockbox Calculation Agent may continue to serve in such role, provided that, during the pendency of any such dispute, it delivers Lockbox Calculation Reports no less frequently than once per week to each of the Lockbox Escrow Agent, Company and Lender.  If, following the commencement of any dispute regarding the existence of a Termination Event, Company and Lender agree to remove the Lockbox Calculation Agent or it is finally determined by a court of competent jurisdiction that a Termination Event has in fact occurred, then the Lockbox Calculation Agent shall be removed and a replacement selected in accordance with Section 7(c).  In all events, removal of the Lockbox Calculation Agent shall only become effective upon the acceptance by the successor Lockbox Calculation Agent of its appointment.  Any resigning or removed Lockbox Calculation Agent shall be entitled to the fees and indemnities set forth herein to the extent incurred or arising, or relating to events occurring, before such resignation or removal.

Consent hereunder shall be provided or denied within ten (10) Business Days after notice and provision of such information as may be reasonably requested by the Lender from the Borrower. Borrower shall immediately notify Lender of such claim. The parties shall consult as to strategy regarding any response to such claim.

(2)           Borrower hereby agrees to grant and hereby grants to Lender effective upon the Notice Event an exclusive royalty-free limited license to use and display the Marks, solely in association with any product or service used or provided in connection with the LFRP in the same general manner and at least as high a level of quality as carried out by Borrower immediately prior to any such Event of Default; provided, that (I) Borrower shall have the right to monitor any such product or service for the purpose of protecting and maintaining the level of quality established by Borrower prior to any such Event of Default; (II) Lender acknowledges that the goodwill and other benefits associated with such Marks shall inure to the benefit of Borrower; and (III) Lender shall not use or omit use of the Marks in any manner which would injure or destroy their value or diminish Borrower’s property rights; and provided, further, that, in the event Borrower advises Lender of any discrepancy in the level of quality of such products or services, Borrower shall have the right to terminate the use and display of the Marks by Lender (but not the other rights licensed hereunder) until such time as the discrepancy is corrected; and

(ii)       Upon the occurrence and during the continuance of an Event of Default, following or in connection with Lender’s exercise of the foreclosure remedies hereunder:

(1)           Lender hereby agrees to grant and hereby grants to Borrower a non-exclusive, perpetual, royalty-free worldwide license, with the right to sublicense, under the Shared Intellectual Property (other than the Marks) to the extent permitted under the In Licenses, for any purpose outside the LFRP on a non-exclusive basis, but limited to a scope or for a use so as to not compete with the LFRP; provided that non-exclusive licensing of Shared Intellectual Property under Internally Developed Product Agreements or under Co-Development Agreements shall not be considered in breach hereof, so long as in no event shall any third party or Affiliate be granted a license or other rights under the Shared Intellectual Property in a way that would allow such third party or Affiliate to operate a funded research or licensing program that would compete with the LFRP.

(2)           Lender hereby agrees to grant and hereby grants to Borrower a non-exclusive, perpetual, royalty-free limited license to use and display the Marks in association with any product or service used or provided in connection with the Borrower’s business outside of the LFRP, within the scope permitted under Section 14(f)(ii)(1), above, in the same general manner and at least as high a level of quality as carried out by Borrower immediately prior to any such foreclosure; provided, that (I) Lender shall have the right to monitor any such product or service for the purpose of protecting and maintaining the level of quality established by Borrower prior to any such foreclosure; (II) Borrower acknowledges that the goodwill and other benefits associated with such Marks shall inure to the benefit of Lender; and (III) Borrower shall not use or omit use of the Marks in any manner which would injure or destroy their value or diminish Lender’s property rights; and provided, further, that, in the event Lender advises Borrower of any discrepancy in the level of quality of such products or services, Lender shall have the right to terminate the use and display of the Marks (but not the other rights licensed hereunder) by Borrower until such time as the discrepancy is corrected; and

(3)           Lender hereby agrees, at Borrower’s sole cost and expense, to make, or to permit Borrower to make, copies of all books, records, data bases, and information (including the handbooks, manuals and sequence information) related to the LFRP and to use all Shared Intellectual Property solely for the purpose of the conduct of the business of Borrower outside the LFRP within the scope permitted under Section 14(f)(ii)(1), above.  For avoidance of doubt, the licenses granted to the Borrower in Section 14(f)(ii) shall survive the termination of this Agreement.  The parties acknowledge that such licenses are licenses of “intellectual property” for the purposes of Section 365 (n) of the Bankruptcy Code.

(g)           Borrower prepared the Duplicate Libraries and delivered the Duplicate Libraries to Fisher Clinical Services, 631 Lofstrand Lane, Rockville, MD 20850 (phone:  (301) 315-2238) or such other secure location or locations as are reasonably acceptable to Borrower and Lender, clearly identified as the Duplicate Libraries prepared for the benefit of Lender, and segregated from property of Borrower.

(j)           Borrower agrees that a breach of any of the covenants contained in this Agreement will cause irreparable injury to Lender, that Lender has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained herein shall be specifically enforceable against Borrower, and Borrower hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants.

(k)           The Borrower shall:  (a) notify in reasonable detail Lender promptly, but in no event later than quarterly (on the earlier of the date on which the Business Report is delivered by the Borrower or the date on which such Business Report is due in each fiscal quarter) after the acquisition, execution or filing thereof, of any (i) License Agreements, LFRP Patents, Co-Development Agreements, payments under which form part of the Collateral, and In Licenses, and (b) on the last day of each quarter provide, in reasonable detail, updates to Schedules 2(b)(i), 2(b)(ii) 2(c), 2(d), 2(h)(i) and 2(h)(ii), which would make the representations and warranties contained in Section 11(c)(i) true, correct and complete as of such date of the delivery of such Business Report.  Upon the delivery and acceptance of such updated schedules by Lender, such schedules will be automatically deemed to amend and restate Schedules 2(b)(i), 2(b)(ii), 2(c), 2(d), 2(h)(i) and 2(h)(ii) hereto.

Section 16.        Standard of Care.  The powers conferred on Lender hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers.  Except for the exercise of good faith and of reasonable care in the accounting for monies actually received by Lender hereunder, Lender shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.  Lender shall be deemed to have exercised reasonable care in the custody and preservation of Collateral in its possession if such Collateral is accorded treatment substantially equal to that which Lender accords its own property.  The Lender shall act as agent hereunder for any other Lenders that become a party to the Loan Agreement after the date hereof and the security interest granted hereunder to the Lender is also granted to the Lender for the benefit of other Lenders.  Except as provided in the Loan Agreement, the Lender shall have no duty to any Lender hereunder and its sole responsibility shall be limited to (i) being named as a secured party hereunder and in any UCC financing statement, intellectual property filing, Lockbox Agreement, any escrow agreement or other documents, instrument or agreement entered into or filed pursuant hereto and (ii) holding any possessory Collateral delivered to it by the Company pursuant hereto, in each case for the benefit of all Lenders.  The Lender is entitled to, but has no obligation to exercise any rights or remedies hereunder or under applicable law.

Section 17.        Remedies Upon Event of Default.

(a)        If, and only if, any Event of Default shall have occurred and be continuing, Lender may exercise in respect of the Collateral (i) all rights and remedies provided for herein, under the Loan Agreement or otherwise available to it, (ii) all the rights and remedies of a secured party on default under the UCC (whether or not the UCC applies to the Collateral), in all relevant jurisdictions, and (iii) the rights to:

(i)       require Borrower to, and Borrower hereby agrees that it will at its cost and expense and upon request of Lender forthwith, assemble all or part of the Collateral as directed by Lender and make it available to Lender at a place to be designated by Lender that is reasonably convenient to both parties;

(ii)       personally or by agents or attorneys, immediately take possession of the Collateral or any part thereof, from Borrower or any other person who has possession of any part thereof, with or without notice or process of law, and for that purpose may enter upon Borrower’s premises where any of the Collateral is located and remove same;

(iii)       foreclose or otherwise enforce Lender’s security interest in any manner permitted by law or provided for in this Agreement;

(iv)       without notice except as may be required by applicable law and that cannot be waived, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any place or places for cash, on credit, or for future delivery, and upon such other terms as Lender may deem commercially reasonable; and

(v)       without notice, exercise any right to set-off or offset provided by law.

(b)           Until an Event of Default has occurred and is continuing, Borrower shall, subject to the provisions of the Loan Agreement and the Lockbox Agreement, continue to collect, at its own cost and expense, all amounts due or to become due Borrower in respect of the Collateral; it being understood and agreed that any and all such collections shall be held in trust for, and be for the benefit of, Lender.  In connection with such collections; provided, no Event of Default shall have occurred and be continuing, Borrower may, subject to the provisions of the Loan Agreement, take such action as Borrower reasonably may deem necessary or advisable to enforce collection of the Collateral.  At any time after an Event of Default has occurred and is continuing, Lender shall have the right to notify the account debtors or obligors under any Collateral of the security interest of Lender in such Collateral and to direct such account debtors or obligors to make payment to Lender (or its designee) of any amounts due or to become due thereunder and enforce collection of any of the Collateral by suit or otherwise and surrender, release or exchange all or any part thereof, or adjust, settle or compromise or extend or renew for any period (whether or not longer than the original period) any indebtedness thereunder or evidence thereby.  If an Event of Default has occurred and is continuing, upon the request of Lender, Borrower shall, at its own cost and expense, notify any parties obligated on any of the Collateral to make payment to Lender (or its designee) of any amounts due or to become due thereunder, and in such event, Lender is authorized to endorse, in the name of Borrower, any item representing any payment on or other proceeds of any of the Collateral.  Borrower irrevocably directs and requires all licensees and account debtors to honor Lender’s request for direct payment and comply with any such request, notwithstanding any directions or instructions to the contrary that may be given by Borrower and agrees that the compliance by such licensee or account debtor with the provisions of this Section shall not be deemed a violation of such party’s contractual agreements with Borrower.

(c)           After delivery to Borrower by Lender of a notice that an Event of Default has occurred and so long as such Event of Default is continuing: (i) all amounts and proceeds (including instruments) received by Borrower in respect of any Collateral shall be received in trust for the benefit of Lender hereunder, shall be segregated from other funds of Borrower, and shall be forthwith paid over to Lender in the same form as so received (with any necessary endorsements) to be held as cash collateral and applied as provided by this Security Agreement; and (ii) Borrower shall not adjust, settle, or compromise the amount or payment of any Collateral, or release wholly or partly any account debtor or obligor thereof, or allow any credit or discount thereon.

(d)           After the occurrence and during the continuation of an Event of Default, (i) Lender may in its own name or in the name of others communicate with account debtors (including Contract Parties to License Agreements and In License Agreements) in order to verify with them to Lender’s reasonable satisfaction the existence, amount and terms of any Collateral and (ii) Lender shall have the right, at Borrower’s cost and expense, to make test verifications of the Collateral in any reasonable manner and through any medium that it considers advisable, and Borrower agrees to furnish all such assistance as Lender may reasonably require in connection therewith.

(e)           Anything contained herein to the contrary notwithstanding, upon the occurrence and during the continuation of an Event of Default, Lender shall have the right (but not the obligation) to bring suit, in the name of Borrower, Lender or otherwise, to enforce any Collateral, in which event Borrower shall, at the request of Lender, do any and all lawful acts and execute any and all documents required by Lender in aid of such enforcement and Borrower shall promptly, upon demand, reimburse and indemnify Lender as provided in the Loan Agreement and Section 19 hereof, as applicable, in connection with the exercise of its rights under this Section 17.

Section 18.        Application of Proceeds.  Except as expressly provided elsewhere in this Agreement, all proceeds received by Lender in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied in good faith to satisfy (to the extent of the net cash proceeds received by Lender) the payment in full in cash of amounts constituting Secured Obligations, in each case equally and ratably to the holders of the Tranche A Loans and Tranche B Loans, in accordance with the amounts of such Loans then outstanding, respectively.

Section 19.        Expenses.

(a)           Borrower agrees to pay to Lender upon demand the amount of any and all costs and expenses, including the reasonable fees and expenses of its counsel and of any experts and agents, that Lender may incur in connection with (i) the custody, preservation, management, enforcement, use or operation of, or the sale of, collection from, or other realization upon, any of the Collateral, (ii) the exercise or enforcement of any of the rights of Lender hereunder, or (iii) the failure by Borrower to perform or observe any of the provisions hereof.  Any costs and expenses payable hereunder shall be deemed to be Secured Obligations and entitled to the security interest hereunder.

(b)           The obligations of Borrower in this Section 19 shall survive the termination of this Agreement and the discharge of Borrower’s other obligations under this Agreement and the Loan Agreement.

Section 20.        Continuing Security Interest; Termination and Release.

(a)           This Agreement shall (i) create a continuing security interest in the Collateral, (ii) remain in full force and effect until the later of the indefeasible payment and performance in full of the Secured Obligations and the expiration or termination of the Loan Agreement (other than indemnification obligations that are unasserted at the time of expiration or termination of Loan Agreement and other contingent obligations that, by their terms, survive the termination hereof and thereof), (iii) be binding upon Borrower and its respective successors and assigns, and (iv) inure, together with the rights and remedies of Lender hereunder, to the benefit of Lender and its successors, transferees and assigns.  The Borrower agrees that its obligations hereunder and the security interest created hereunder shall continue to be effective or be reinstated, as applicable, if at any time payment, or any part thereof, of all or any part of the Secured Obligations is rescinded or must otherwise be restored by the Lender upon the bankruptcy or reorganization of the Borrower or otherwise.

(b)           Upon the payment and performance in full of all Secured Obligations (other than indemnification obligations that are unasserted as of the expiration or termination of the Loan Agreement and other contingent obligations not then due and payable that, by their terms, survive the termination hereof), the security interest granted hereby shall terminate and all rights to the Collateral shall revert to Borrower.  Upon such termination or any release of Collateral or any part thereof in accordance with the provisions of Section 10.02(b) of the Loan Agreement, the Lender shall, upon the request and at the sole cost and expense of the Borrower, assign, transfer and deliver to Borrower, against receipt and without recourse to or warranty by the Lender except as to the fact that the Lender has not encumbered the released assets, such of the Collateral or any part thereof to be released (in the case of a release) as may be in possession of the Lender and as shall not have been sold or otherwise applied pursuant to the terms hereof, and, with respect to any other Collateral, proper documents and instruments (including UCC 3 termination financing statements or releases) acknowledging the termination hereof and the security interest granted hereby or the release of such Collateral, as the case may be.

Section 21.        Miscellaneous.

(a)           Notices.  All notices, consents, waivers and communications hereunder given by any party to any other party shall be given pursuant to Section 13.04 of the Loan Agreement.

(b)           Effectiveness; Entire Agreement.  This Agreement, together with the other Transaction Documents and Schedules and Exhibits hereto and thereto (which are incorporated herein by reference), constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings and negotiations, both written and oral, among the parties with respect to the subject matter of this Agreement.  No representation, inducement, promise, understanding, condition or warranty not set forth herein (or in Schedules or Exhibits hereto) has been made or relied upon by any party hereto.  None of this Agreement, nor any provision hereof, is intended to confer upon any Person other than the parties hereto any rights or remedies hereunder.

(c)           Amendments; No Waivers.

(i)       This Agreement or any term or provision hereof may not be amended, changed or modified except with the written consent of the parties hereto and subject to any consent required under the Loan Agreement; provided, that Lender may amend this agreement without the consent of the Borrower in order to add mechanics related to syndication of the Loan to one or more additional Lenders so long as such amendments do not in any way alter Borrower’s rights or obligations hereunder. Lender may take any action that is permitted under the Loan Agreement or hereunder.  No waiver of any right hereunder shall be effective unless such waiver is signed in writing by the party against whom such waiver is sought to be enforced.  To the extent Borrower transfers any of the Collateral to any of its Subsidiaries, then such Subsidiaries shall execute a joinder to this Agreement or a new agreement substantially similar to this Agreement and any other applicable Loan Documents, in each case in form and substance reasonably satisfactory to the Lender, to confirm the continued security interest of the Lender in such Collateral.

Confidential materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote such omission.

(ii)       No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.  The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

(d)           Successors and Assigns.  The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, and any reference herein to a party shall be deemed a reference to such party’s successors and assigns, if any.  Borrower shall not be entitled to assign any of its obligations and rights hereunder or any other Transaction Documents without the prior written consent of Lender.  Lender may assign this Agreement and any of its rights hereunder without restriction.

(e)           Severability.  If any provision of this Agreement is held to be invalid or unenforceable, the remaining provisions shall nevertheless be given full force and effect.
