ARTICLE II

AMOUNT AND TERMS OF THE CREDIT FACILITY

Section 2.1. Advances. The Pabeti Lender and the LV Lenders may elect, in their respective sole discretion and subject to the terms and conditions of this Agreement, to make advances (the “Advances”) to the Borrower from the Closing Date to and until (but not including) the Termination Date.

Section 2.2. The Notes. The Advances by the Pabeti Lender and the LV Lenders shall be evidenced by the Notes. The Agent is hereby irrevocably authorized by the Borrower to enter on the schedule forming a part of the Notes, or otherwise in its records, appropriate notations evidencing the date and the amount of each Advance, and, in the absence of manifest error, such notations shall constitute prima facie evidence thereof. The Agent is hereby irrevocably authorized by the Borrower to attach to and make a part of each of the Notes a continuation of any such schedule as and when required. No failure on the part of the Agent to make any notation as provided in this Section 2.2 shall in any way affect any Advance or the rights of the Lenders under the Loan Documents or the Obligations of the Borrower.

Section 2.3. Notice and Manner of Borrowing.

(a) Whenever the Borrower desires to obtain an Advance hereunder, the Borrower shall give notice to the Agent (which notice shall be irrevocable) by e-mail or telephone received by no later than 10:00 am., New York, New York time, on the date that is one (1) Business Day before the day on which the requested Advance is to be made. Each such notification by telephone pursuant to this Section 2.3 shall be immediately followed by a written confirmation thereof by the Borrower in substantially the form of Exhibit C attached hereto (a “Notice of Borrowing”); provided that, if such written confirmation differs in any material respect from the action taken by the Agent, the records of the Agent shall be conclusive absent manifest error. Each Notice of Borrowing shall specify (i) the requested date of such borrowing (which shall be a Business Day), and (ii) the principal amount of Advance to be borrowed. Upon receipt of a Notice of Borrowing from the Borrower, the Agent shall distribute such Notice of Borrower to each of the Pabeti Lender and the LV Lenders requesting their approval of the Advance requested in such Notice of Borrowing (each, an “Advance Approval”).

(b) To the extent that each of the Pabeti Lender and the LV Lenders agree to fund a amount to the Borrower requested in a Notice of Borrower referred to in Section 2.3(a) above and subject to the terms and conditions hereof, the applicable Lender shall make available to the Agent, in immediately available funds, on the date upon which any Advance is to be made to the Borrower, the entire amount of the requested Advance; provided that, in the case of an Advance by the LV Lenders, each LV Lender shall be required to make available to the Agent such LV Lender’s Advance Percentage of the requested Advance. In the event that any LV Lender refuses or fails to make available to the Agent such LV Lender’s Advance Percentage of the requested Advance (the “Advance Shortfall”), the remaining LV Lenders shall immediately make available to the Agent the amount of the Advance Shortfall based on each such LV Lender’s Advance Percentage (not taking into account in such instance the Advance Percentage of the LV Lender that refused or failed to make available its share of the required Advance). The Agent shall, in turn, disburse each Advance on the effective date specified therefore by wire transfer to the Deposit Account. In no event shall the Agent (in its capacity as the Agent) have any obligation to fund any Advances.

(c) Notwithstanding the foregoing, in no event shall the Pabeti Lender and/or the LV Lenders have any obligation to make an Advance to the Borrower hereunder to the extent that the requested Advance was not approved by all Lenders as described in Section 2.3(a) above or, in the case of the Pabeti Lender, the amount of the requested Advance from the Pabeti Lender exceeds, together with all other Pabeti Advance Amounts, the Maximum Pabeti Lender Advance Amount, and, in the case of the LV Lenders, the amount of the requested Advance from the LV Lenders exceeds the Maximum LV Lenders Advance Amount.

(d) All of the Advances shall be secured by the Collateral.

Section 2.4. Interest; Application of Payments; Usury.

(a) Interest. The principal amount of the Advances shall bear interest at the rate of twelve percent (12%) per annum and shall be calculated based on a year of 360 days for the actual number of days elapsed.

(b) Application of Payments. Any payments required to be made by the Borrower hereunder shall be applied to the Obligations on the first Business Day after receipt by the Agent in the Agent’s general account. The Agent shall apply such payments in satisfaction of the Obligations in such order as the Agent determines in its sole discretion.

(c) Usury. No change in the interest rate hereunder shall be put into effect which would result in an interest rate greater than the highest rate permitted by law. Notwithstanding anything to the contrary contained in any Loan Document, all agreements which either now are or which shall become agreements between the Borrower and the Lenders are hereby limited so that in no contingency or event whatsoever shall the total liability for payments in the nature of interest, additional interest and other charges exceed the applicable limits imposed by any applicable usury laws. If any payments in the nature of interest, additional interest and other charges made under any Loan Document are held to be in excess of the limits imposed by any applicable usury laws, it is agreed that any such amount held to be in excess shall be considered payment of principal hereunder, and the Obligations evidenced hereby shall be reduced by such amount so that the total liability for payments in the nature of interest, additional interest and other charges shall not exceed the applicable limits imposed by any applicable usury laws, in compliance with the desires of the Borrower and the Lenders. This provision shall never be superseded or waived and shall control every other provision of the Loan Documents and all agreements between the Borrower and the Lenders, or their successors and assigns.

Section 2.5. Time for Principal and Interest Payments; Mandatory Repayment, Payment on Non-Business Days.

(a) Time for Principal and Interest Payments; Mandatory Repayment. The outstanding principal amount of all Advances and all accrued and unpaid interest on the Advances shall be due and payable on the Termination Date; provided, however, that if at any time after the Closing Date the Borrower shall have funds in excess of $5 million dollars (as reflected on Borrower’s Books and Records) available for use as “working capital” on the last day of any month prior to the Termination Date, within one Business Day following the date of determination thereof, the amount of such funds that are in excess of $5 million (hereinafter “Surplus Working Capital”) shall be applied as a mandatory repayment of the principal amount of all Advances and all accrued and unpaid interest on the Advances. In the event that the Surplus Working Capital is insufficient to fully repay all the Obligations, then the Surplus Working Capital shall be applied to repay the Obligations pro rata amongst the Lenders in relation to their respective portions of the outstanding Obligations immediately prior to such repayment.

(b) Payment on Non-Business Days. Whenever any payment to be made hereunder shall be stated to be due on a day which is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest on the Advances hereunder.

Section 2.6 No Voluntary Prepayment. The Borrower may not prepay the Advances, in whole or in part, except pursuant to Section 2.5(a) herein.

Section 2.7 Use of Proceeds. The Borrower shall use the proceeds of Advances for the purpose of funding it general working capital costs and expenses.

Section 2.8 Liability Records. The Agent may maintain from time to time, at its discretion, records as to the Obligations. All entries made on any such record, if presented to the Borrower, shall be presumed correct until the Borrower establishes the contrary. Upon the Agent’s demand, the Borrower will admit and certify in writing the exact principal balance of the Obligations that the Borrower then asserts to be outstanding. Any billing statement or accounting rendered by the Agent shall be conclusive and fully binding on the Borrower unless the Borrower gives the Agent written notice of its objection to any billing statement or accounting within thirty (30) days after receipt thereof.

Section 2.9 Single Loan. All Advances to the Borrower and all of the other Obligations of the Borrower arising under this Agreement and the other Loan Documents shall constitute one general obligation of the Borrower secured by all of the Collateral.

Section 2.10 Grants, Rights and Remedies. The Liens and the Security Interest granted pursuant to Article III may be independently granted by the Loan Documents. This Agreement and such other Loan Documents supplement each other, and the grants, priorities, rights and remedies of the Agent hereunder and thereunder are cumulative.

ARTICLE III

SECURITY INTEREST; OCCUPANCY; SETOFF

Section 3.1. Grant of Security Interest. The Borrower hereby pledges, assigns and grants to the Agent, for the benefit of itself and as agent for the Lenders, a continuing first priority Lien and security interest in the Collateral (collectively referred to as the “Security Interest”), as security for the payment and performance of the Indebtedness due hereunder. Upon request by the Agent, the Borrower will grant to the Agent, for the benefit of itself and as agent for the Lenders, a security interest in all commercial tort claims that the Borrower may have against any Person.

Section 3.2. Lien Perfection; Further Assurances. The Borrower shall execute such instruments, assignments, mortgages, or documents as are necessary to perfect the Agent’s Liens upon any of the Collateral and shall take such other action as may be reasonably required to perfect or to continue the perfection of the Agent’s Liens upon the Collateral. The Borrower hereby irrevocably authorizes the Agent at any time and from time to time to file in any UCC jurisdiction any initial financing statements and amendments thereto that (a) indicate the Collateral (i) as all assets of the Borrower or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC of the State of Delaware or such other jurisdiction, or (ii) as being of an equal or lesser scope or with

greater detail, and (b) contain any other information required by part 5 of Article 9 of the UCC of the State of the Borrower’s location for the sufficiency or filing office acceptance of any financing statement or amendment, including (i) whether the Borrower is an organization, the type of organization and any organization identification number issued to the Borrower, and, (ii) in the case of a financing statement filed as a fixture filing or indicating Collateral as as-extracted collateral or timber to be cut, a sufficient description of real property to which the Collateral relates. The Borrower agrees to furnish any such information to the Agent promptly upon request. The Borrower also ratifies its authorization for the Agent to have filed in any UCC jurisdiction any initial financing statements or amendments thereto if filed prior to the date hereof. At the Agent’s request, the Borrower shall also promptly execute or cause to be executed and shall deliver to the Agent any and all documents, instruments and agreements deemed necessary by the Agent to give effect to or carry out the terms or intent of the Loan Documents hereunder.

to become due under, and all other rights of the Borrower with respect to, any and all policies of insurance now or at any time hereafter covering the Collateral or any evidence thereof or any business records or valuable papers pertaining thereto, and the Borrower hereby directs the issuer of any such policy to pay all such monies directly to the Agent. At any time, whether or not a Default Period then exists, the Agent may (but need not), in the Agent’s name or in the Borrower’s name, execute and deliver proof of claim, receive all such monies, endorse checks and other instruments representing payment of such monies, and adjust, litigate, compromise or release any claim against the issuer of any such policy. Any monies received as payment for any loss under any insurance policy mentioned above (other than liability insurance policies), or as payment of any award or compensation for condemnation or taking by eminent domain, shall be paid over to the Agent to be applied, at the option of the Agent, either to the prepayment of the Obligations or shall be disbursed to the Borrower under staged payment terms reasonably satisfactory to the Agent for application to the cost of repairs, replacements, or restorations.

Section 3.5. Occupancy.

(a) The Borrower hereby irrevocably grants to the Agent the right to take possession of the Leased Real Property at any time following an Event of Default within three (3) days of the Borrower’s receipt of notice thereof from the Agent, to the exclusion of Borrower.

(b) The Agent may use the Leased Real Property only to hold, process, manufacture, sell, use, store, liquidate, realize upon or otherwise dispose of items that are Collateral and for other purposes that the Agent may in good ▇▇▇▇▇ ▇▇▇▇ to be related or incidental purposes.

(c) The Agent’s right to hold the Leased Real Property shall cease and terminate upon the earlier of (i) payment in full and discharge of all Obligations and termination of the Credit Facility, and (ii) final sale or disposition of all items constituting Collateral and delivery of all such items to purchasers.

(d) The Agent shall not be obligated to pay or account for any rent or other compensation for the possession, occupancy or use of any of the Leased Real Property; provided, however, that if the Agent does pay or account for any rent or other compensation for the possession, occupancy or use of any of the Leased Real Property, the Borrower shall reimburse the Agent promptly for the full amount thereof. In addition, the Borrower will pay, or reimburse the Agent for, all taxes, fees, duties, imposts, charges and expenses at any time incurred by or imposed upon the Agent by reason of the provisions of this Section 3.5.

Section 3.6. License. Without limiting the generality of any other Security Document, the Borrower hereby grants to the Agent for so long as any Obligations remain outstanding hereunder a non-exclusive, worldwide and royalty-free license to use or otherwise exploit all Intellectual Property Rights of the Borrower following an Event of Default for the purpose of: (a) completing the manufacture of any in-process materials during any Default Period so that such materials become saleable Inventory, all in accordance with the same quality standards previously adopted by the Borrower for its own manufacturing; and (b) selling, licensing, leasing or otherwise disposing of any or all Collateral during any Default Period.

Section 3.7. Setoff. The Agent may at any time or from time to time, at its sole discretion and without demand and without notice to anyone, setoff any liability owed to the Borrower by the Lenders, whether or not due, against any outstanding Obligations that are due and payable under the Loan Documents.

Section 3.8. Collateral. This Agreement does not contemplate a sale of accounts, contract rights or chattel paper, and, as provided by law, the Borrower is entitled to any surplus and shall remain liable for any deficiency. The Agent’s duty of care with respect to Collateral in its possession (as imposed by law) shall be deemed fulfilled if it exercises reasonable care in physically keeping such Collateral, or in the case of Collateral in the custody or possession of a bailee or other third Person, exercises reasonable care in the selection of the bailee or other third Person, and the Agent need not otherwise preserve, protect, insure or care for any Collateral. The Agent shall not be obligated to preserve any rights the Borrower may have against prior parties, to realize on the Collateral at all or in any particular manner or order or to apply any cash proceeds of the Collateral in any particular order of application. The Agent has no obligation to clean up or otherwise prepare the Collateral for sale. The Borrower waives any right it may have to require the Agent or the Lenders to pursue any third Person for any of the Obligations.

Section 3.9. Survival. The Liens, lien priority, and other rights and remedies granted to the Agent and the Lenders pursuant to this Agreement and the other Loan Documents (specifically including, but not limited to, the existence, perfection and priority of the Liens and security interests provided herein and therein) shall not be modified, altered or impaired in any manner by any other financing or extension of credit or incurrence of debt by the Borrower, or by any other act or omission whatsoever.

Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers, and duties of the retiring Agent and the term “Agent” shall mean such successor agent and the retiring Agent’s appointment, powers, and duties as the Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Section 8.8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Agent under this Agreement.

Section 8.9. Collateral Matters.

(a) With the prior consent of each of the Lenders, the Agent is authorized to release any Lien upon any Collateral.

(b) Upon receipt by the Agent of any authorization required pursuant to Section 8.9(a) to release any Liens upon particular types or items of Collateral, and upon at least five (5) Business Days prior written request (or such shorter time period as the Lenders may agree) by the Borrower, the Agent shall (and is hereby irrevocably authorized by the Lenders to) execute such documents as may be necessary to evidence the release of the Liens upon such Collateral; provided, however, that (i) the Agent shall not be required to execute any such document on terms which, in the Agent’s judgment, would expose the Agent to liability or create any obligation or entail any consequence other than the release of such Liens without recourse or warranty, and (ii) such release shall not in any manner discharge, affect, or impair the Obligations or any Liens (other than those expressly being released) upon (or obligations of the Borrower in respect of) all interests retained by the Borrower, including the proceeds of any sale, all of which shall continue to constitute part of the Collateral.

Section 8.10. Restrictions on Actions by the Lenders; Sharing of Payments.

(a) Each of the Lenders agrees that it shall not, without the consent of all of the Lenders, set-off against the Obligations, any amounts owing by such Lender to the Borrower or any accounts of the Borrower now or hereafter maintained with such Lender. Each of the Lenders further agrees that it shall not, unless agreed to by all of the Lenders, take or cause to be taken any action to enforce its rights under this Agreement or against the Borrower, including the commencement of any legal or equitable proceedings, to foreclose any Lien on, or otherwise enforce any security interest in, any of the Collateral.

(b) If at any time or times any Lender shall receive (i) by payment, foreclosure, set-off or otherwise, any proceeds of Collateral or any payments with respect to the Obligations owing to such Lender arising under, or relating to, this Agreement or the other Loan Documents, except for any such proceeds or payments received by such Lender from the Agent pursuant to the terms of this Agreement, or (ii) payments from the Agent in excess of such Lender’s portion of all such distributions by the Agent, such Lender shall promptly turn the same over to the Agent, in kind, and with such endorsements as may be required to negotiate the same to the Agent, or in same day funds, as applicable, for the account of all of the Lenders and for application to the Obligations in accordance with the applicable provisions of this Agreement.

Section 8.11. Agency for Perfection. Each Lender hereby appoints each other Lender as agent for the purpose of perfecting the Lenders’ security interest in assets which, in accordance with Article 9 of the UCC, can be perfected only by possession. Should any Lender (other than the Agent) obtain possession of any such Collateral, such Lender shall notify the Agent thereof and, promptly upon the Agent’s request therefor, shall deliver such Collateral to the Agent or otherwise deal with such Collateral in accordance with the Agent’s instructions.

Section 8.12. Payments by the Agent to the Lenders. All payments to be made by the Agent to the Lenders shall be made by bank wire transfer or internal transfer of immediately available funds to each Lender pursuant to wire transfer instructions delivered in writing to the Agent, or pursuant to such other wire transfer instructions as each Lender may designate for itself by written notice to the Agent. Concurrently with each such payment, the Agent shall identify whether such payment (or any portion thereof) represents principal, premium, or interest.

Section 8.13. Concerning the Collateral and the Related Loan Documents. Each Lender agrees that any action taken by the Agent or the Lenders, as applicable, in accordance with the terms of this Agreement or the other Loan Documents relating to the Collateral, and the exercise by the Agent or the Lenders, as applicable, of their respective powers set forth therein or herein, together with such other powers that are reasonably incidental thereto, shall be binding upon all of the Lenders.

Section 8.14. Relation Among the Lenders. The Lenders are not partners or co-venturers, and no Lender shall be liable for the acts or omissions of, or (except as otherwise set forth herein in case of the Agent) authorized to act for, any other Lender.

ARTICLE IX

MISCELLANEOUS

Section 9.1. No Waiver; Cumulative Remedies; Compliance with Laws. No failure or delay by the Agent in exercising any right, power or remedy under the Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy under the Loan Documents. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law. The Agent may comply with any applicable state, provincial or federal law requirements in connection with a disposition of the Collateral and such compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.

Section 9.2. Amendments, Etc. No amendment, modification, termination or waiver of any provision of any Loan Document or consent to any departure by the Borrower therefrom or any release of a Security Interest shall be effective unless the same shall be in writing and signed by the Agent, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances.

Section 9.3. Notices; Communication of Confidential Information; Requests for Accounting. Any notice or request hereunder may be given to the Borrower or the Agent and the Lenders at the respective addresses set forth below or as may hereafter be specified in a notice designated as a change of address under this Section 9.3. Any notice or request hereunder shall be given by registered or certified mail, return receipt requested, hand delivery, overnight mail or facsimile transmission (confirmed by mail). Notices and requests shall be, in the case of those by hand delivery, deemed to have been given when delivered to any officer of the Party to whom it is addressed, in the case of those by registered or certified mail or overnight mail, deemed to have been given three (3) Business Days after the date when deposited in the mail or with the overnight mail carrier, and, in the case of a facsimile transmission, when confirmed.

or such other address as may be designated in writing hereafter in accordance with this Section 9.3 by such Person.

Section 9.4. Further Documents. The Borrower will from time to time execute, deliver, endorse and authorize the filing of any and all instruments, documents, conveyances, assignments, security agreements, financing statements, and other agreements and writings that the Agent may reasonably request in order to secure, protect, perfect or enforce the Security Interest or the Agent or the Lenders’ rights under the Loan Documents (but any failure to request or assure that the Borrower executes, delivers, endorses or authorizes the filing of any such item shall not affect or impair the validity, sufficiency or enforceability of the Loan Documents and the Security Interest, regardless of whether any such item was or was not executed, delivered or endorsed in a similar context or on a prior occasion). Promptly upon the Agent’s request, the Borrower shall execute and deliver to the Agent a power of attorney authorizing the Agent to execute in the name, and on behalf, of the Borrower any and all documents reasonably necessary to consummate a sale of Collateral after an Event of Default.

Section 9.5. Costs and Expenses. All actual costs and expenses, including reasonable attorneys’ fees, incurred by the Agent and the Lenders in connection with the Obligations, this Agreement, the Loan Documents, and any other document or agreement related hereto or thereto, and the transactions contemplated hereby, including all such costs, expenses and fees incurred in connection with the negotiation, preparation, execution, amendment, administration, performance, collection and enforcement of the Loan Documents and all such documents and agreements and the creation, perfection, protection, satisfaction, foreclosure or enforcement of the Security Interest, shall be due and payable by the Borrower on the Termination Date.

Section 9.6. Indemnity. In addition to the payment of expenses pursuant to Section 9.5, the Borrower shall indemnify, defend and hold harmless the Agent and the Lenders, and any of their participants, parent corporations, subsidiary corporations, affiliated corporations, successor corporations, and all present and future officers, directors, employees, attorneys and agents of the foregoing (the “Indemnitees”) from and against any of the following (collectively, the “Indemnified Liabilities”):

(i) Any and all transfer taxes, documentary taxes, assessments or charges made by any governmental authority by reason of the execution and delivery of the Loan Documents or the making of the Advances; and

(ii) Any and all other liabilities, losses, damages, penalties, judgments, suits, claims, costs and expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel) in connection with the foregoing and any other investigative, administrative or judicial proceedings, whether or not such Indemnitee shall be designated a party thereto, which may be imposed on, incurred by or asserted against any such Indemnitee, in any manner related to or arising out of or in connection with the making of the Advances and the Loan Documents or the use or intended use of the proceeds of the Advances.

Notwithstanding the foregoing, the Borrower shall not be obligated to indemnify any Indemnitee for any Indemnified Liability caused by the gross negligence or willful misconduct of such Indemnitee, as finally determined by a court of competent jurisdiction.

If any investigative, judicial or administrative proceeding arising from any of the foregoing is brought against any Indemnitee, upon such Indemnitee’s request, the Borrower, or counsel designated by the Borrower and satisfactory to the Indemnitee, will resist and defend such action, suit or proceeding to the extent and in the manner directed by the Indemnitee, at the Borrower’s sole cost and expense. Each Indemnitee will use its best efforts to cooperate in the defense of any such action, suit or proceeding. If the foregoing undertaking to indemnify, defend and hold harmless may be held to be unenforceable because it violates any law or public policy, the Borrower shall nevertheless make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law.

Section 9.7. Participants. Each Lender and its participants, if any, are not partners or joint venturers, and such Lender shall not have any liability or responsibility for any obligation, act or omission of any of its participants. All rights and powers specifically conferred upon any Lender may be transferred or delegated to any Lender’s participants, successors or assigns.

Section 9.8. Execution in Counterparts; Telefacsimile Execution. This Agreement and the other Loan Documents may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same instrument. Delivery of an executed counterpart of this Agreement or any other Loan Document by telefacsimile shall be equally as effective as delivery of an original executed counterpart of this Agreement or such other Loan Document. Any party delivering an executed counterpart of this Agreement or any other Loan Document by telefacsimile also shall deliver an original executed counterpart of this Agreement or such other Loan Document but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement or such other Loan Document.

Section 9.9. Retention of Borrower’s Records. The Agent and the Lenders shall have no obligation to maintain any electronic records or any documents, schedules, invoices, agings, or other papers delivered to the Agent or any Lender by the Borrower or in connection with the Loan Documents for more than thirty (30) days after receipt by the Agent or any Lender. If there is a special need to retain specific records, the Borrower must inform the Agent of its need to retain those records with particularity, which must be delivered in accordance with the notice provisions of Section 9.3 within thirty (30) days of the Agent or any Lender taking control of same.

Section 9.10. Binding Effect; Assignment; Complete Agreement; Sharing Information; Confidentiality. The Loan Documents shall be binding upon and inure to the benefit of the Borrower and the Agent and the Lenders and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights thereunder or any interest therein without the Agent’s prior written consent. To the extent permitted by law, the Borrower waives and will not assert against any assignee any claims, defenses or set-offs which the Borrower could assert against the Agent. This Agreement, together with the Loan Documents, comprises the complete and integrated agreement of the Parties on the subject matter hereof and supersedes all prior agreements, written or oral, on the subject matter hereof. To the extent that any provision of this Agreement contradicts other provisions of the Loan Documents, this Agreement shall control. The Agent and the Lenders may share information regarding the Borrower with their respective accountants, lawyers and other advisors and the Borrower waives any right of confidentiality it may have with respect to all such sharing of information. Any other provision of this Agreement or the other Loan Documents notwithstanding, the Agent and the Lenders and such other parties shall use reasonable efforts in accordance with their policies and procedures in place from time to time to maintain the confidentiality of the financial and business information they obtain from the Borrower and to prevent the inappropriate dissemination and disclosure thereof; provided that, nothing in this Agreement or the other Loan Documents shall prohibit the Agent and the Lenders from providing any information regarding the Borrower to internal auditors, other operating divisions of the Agent, any Lender, any Lender affiliates, or in response to a request from a regulatory authority having jurisdiction over the Agent or any Lender.

Section 9.11. Severability of Provisions. Any provision of this Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof.

Section 9.12. Headings. Article, Section and subsection headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

Section 9.13. Election of Remedies. If the Agent may, under applicable law, proceed to realize its benefits under any of the Loan Documents giving the Agent a security interest in or Lien upon any Collateral, whether owned by the Borrower, either by judicial foreclosure or by non judicial sale or enforcement, the Agent may, at its sole option, determine which of its remedies or rights it may pursue without affecting any of its rights and remedies under this Section. If, in the exercise of any of its rights and remedies, the Agent shall forfeit any of its rights or remedies, including its right to enter a deficiency judgment against the Borrower, whether because of any applicable laws pertaining to “election of remedies” or the like, the Borrower hereby consents to such action by the Agent and waives any claim based upon such action. Any election of remedies that results in the denial or impairment of the right of the Agent to seek a deficiency judgment against the Borrower shall not impair the Borrower’s obligation to pay the full amount of the Obligations. In the event the Agent shall bid at any foreclosure or trustee’s sale or at any private sale permitted by law or the Loan Documents, the Agent may bid all or less than the amount of the Obligations and the amount of such bid need not be paid by the Agent but shall be credited against the Obligations. The amount of the successful bid at any such sale, whether the Agent or any other party is the successful bidder, shall be conclusively deemed to be the fair market value of the Collateral and the difference between such bid amount and the remaining balance of the Obligations shall be conclusively deemed to be the amount of the Obligations guaranteed under this Section, notwithstanding that any present or future law or court decision or ruling may have the effect of reducing the amount of any deficiency claim to which the Agent might otherwise be entitled but for such bidding at any such sale.

Section 9.14. Governing Law; Jurisdiction, Venue.

(a) The Loan Documents shall be governed by and construed in accordance with the substantive laws (other than conflict laws) of the State of New York, except that at all times the provisions for the creation, perfection and enforcement of the Liens and Security Interest granted by the Borrower pursuant to the Loan Documents with respect to the Collateral may be governed by, and construed according to, the laws of the state where such Collateral is located. The Parties hereto acknowledge and agree that the State and/or Federal courts located in the County of New York, State of New York shall have exclusive jurisdiction over this Agreement and the other Loan Documents and any disputes or matters arising hereunder and thereunder.

(b) THE BORROWER, THE AGENT AND THE LENDERS DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND/OR OF ARBITRATION, THE BORROWER, THE AGENT AND THE LENDERS WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE BETWEEN ANY OF THE AGENT OR THE LENDERS AND/OR THE BORROWER ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT, ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS RELATED HERETO OR THERETO.

Section 3. REPRESENTATIONS AND WARRANTIES.

Each Grantor represents and warrants to Agent, in addition to the representations and warranties in Credit Agreement and Loan Documents (as defined in the Credit Agreement), that:

Such Grantor does not own, in whole or in part, any Patent, Trademark, Copyright, or other Intellectual Property which is the subject of a registration or application in the United States Patent and Trademark Office, United States Copyright Office, any similar office or agency of the United States, any State, any other country or political subdivision, any Internet Domain Name registrar, or any other registry, except as set forth in Schedule I, Schedule II, Schedule III, and Schedule IV, respectively, hereto.

(b)

such Grantor is the sole owner of the Intellectual Property listed on Schedules I to IV hereto (as such schedules may be amended or supplemented from time to time) identified as owned by such Grantor, and all registrations and applications for such Intellectual Property are standing in the name of such Grantor.

(c)

no Intellectual Property has been licensed or sublicensed by any Grantor to any Affiliate or third party, except under the licenses disclosed in Schedules I to IV hereto.

(d)

all Intellectual Property owned by such Grantor, including the items set forth on Schedules I to IV, and, to such Grantor’s knowledge, all Intellectual Property licensed to such Grantor, is subsisting in good standing, valid, and enforceable and such Grantor performed all acts and has paid all renewal, maintenance, and other fees and taxes required to maintain, each registration and application for Intellectual Property owned by such Grantor in full force and effect.

(b)
