Section I.9. Voluntary Prepayments and Mandatory Reduction/ Collateralization of Letters of Credit

. (a) The Borrower may, at any time and from time to time upon at least three Bank Business Days’ notice to the Lender (such notice to be provided in accordance with Section 9.02) stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given the Borrower shall, prepay in whole or in part the outstanding aggregate principal amount of the Advances and the Reimbursement Obligations, together with accrued interest to the date of such prepayment on the aggregate principal amount prepaid.

If, on any Bank Business Day (a “Trigger Date”), the sum of (x) the aggregate principal amount of the Advances outstanding at such time plus (y) the aggregate principal amount of the Reimbursement Obligations at such time plus (z) the aggregate Available Amount in respect of all Letters of Credit at such time, exceeds the Credit Facility Available Amount by more than $500,000 at such time, the Issuer shall, by 11:00 a.m. (New York City time) on such Bank Business Day, notify the Borrower of the occurrence of such Trigger Date in accordance with Section 9.02.

If the Issuer shall notify the Borrower of the occurrence of any Trigger Date, the Borrower shall, by 2:00 p.m. (New York City time) on the day that is two Bank Business Days after the day of such notification, terminate or amend existing Letters of Credit sufficient to reduce the aggregate Available Amount of such Letters of Credit to the amount which is the greater of (i) the amount which is equal to the Credit Facility Available Amount on the date of such notification less the sum of (x) the aggregate principal amount of the Advances outstanding at such time plus (y) the aggregate principal amount of the Reimbursement Obligations at such time and (ii) zero; provided, however, that the Borrower shall have no obligation to amend or terminate any existing Letter of Credit pursuant to this clause (c) if it has used commercially reasonable efforts to induce the beneficiary of such Letter of Credit to terminate or amend such Letter of Credit, including, without limitation, offering cash collateral to such beneficiary, and such beneficiary has refused to so amend or terminate such Letter of Credit.

If, after taking the actions required pursuant to clause (c) above, the sum of (x) the aggregate principal amount of the Advances outstanding at such time plus (y) the aggregate principal amount of the Reimbursement Obligations at such time plus (z) the aggregate Available Amount in respect of all Letters of Credit at such time, still exceeds the Credit Facility Available Amount on the date of such notification, then the Borrower shall, by 2:00 p.m. (New York City time) on the day that is two Bank Business Days after the day the Issuer notifies the Borrower of the occurrence of such Trigger Date and subject to the provisions of Section 2.11(c) below:

(i) first, prepay Advances, if any, plus interest thereon as directed by the Lender or the Issuer, in an amount which is the lesser of (A) the aggregate principal amount of the Advances outstanding at such time and (B) the amount by which the sum of (x) the aggregate principal amount of the Advances outstanding at such time plus (y) the aggregate principal amount of the Reimbursement Obligations at such time plus (z) the aggregate Available Amount in respect of all Letters of Credit at such time (after giving effect to any actions take pursuant to clause (c) above), exceeds the Credit Facility Available Amount on the day of such notification; and

(ii)second, pay to the Paying Agent in same day funds the amount which is the lesser of (1) the aggregate Available Amount of all then outstanding Letters of Credit and (2) the amount by which the sum of (x) the aggregate principal amount of the Advances outstanding at such time (after giving effect to any actions take pursuant to clause (d)(i) above) plus (y) the aggregate principal amount of the Reimbursement Obligations at such time plus (z) the aggregate Available Amount in respect of all Letters of Credit at such time (after giving effect to any actions take pursuant to clause (c) above), exceeds the Credit Facility Available Amount on the day of such notification (such excess, an “Excess Payment”). The Paying Agent shall, at the direction of the Issuer it its sole discretion, either:

(A)pay such Excess Payment, or a portion thereof, pro rata to the beneficiaries under the outstanding Reducing Letters of Credit, ratably in accordance with their respective Available Amounts, pursuant to the payment instructions furnished to the Lender or the Issuer under Section 3.03(b)(ii)(B); and/or

(B)pay such Excess Payment, or a portion thereof, into the Collateral Account in accordance with Section 2.11(b).

The Paying Agent shall, not later than one Bank Business Day after the application of any funds pursuant to this Section 2.06(d)(ii), notify the Borrower in accordance with Section 9.02 as to the details of how such funds were applied.

Section I.10. Interest

. The Borrower shall pay interest (without having regard to any Collateral provided by or on behalf of the Borrower) on (a) the unpaid principal amount of each Advance owing to each Lender Party from the date of such Advance until such principal amount shall be paid in full and (b) the full amount of each Reimbursement Obligation owing to the Issuer from the date such Reimbursement Obligation is incurred until such Reimbursement Obligation is paid in full, in each case at the applicable rate per annum, and payable at the times, set forth in the Letter Agreement.

Section I.11. Fees

. The Borrower shall pay to the Issuer the fees set forth in the Letter Agreement.

Section I.12. Payments and Computations

. The Borrower shall make each payment hereunder and under the Letter Agreement, irrespective of any right of counterclaim or set-off, not later than 2:00 p.m. (New York City time) on the day when due in U.S. dollars in same day funds to the applicable Lender Party at the deposit account designated by such Lender Party to the Borrower.

(a)All computations of interest under Section 2.07 and Section 2.11(d) and the Letter Agreement and of the ongoing fees under Section 2.08 and the Letter Agreement shall be made on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fee is payable. Each determination of such interest rate or fee by any Lender Party shall be conclusive and binding for all purposes, absent manifest error.

(b)Whenever any payment hereunder or under the Letter Agreement shall be stated to be due on a day other than a Bank Business Day, such payment shall be made on the next succeeding Bank Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fee, as the case may be.

Section I.13. Evidence of Debt

. (a) Each Lender Party shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender Party resulting from each Advance or Reimbursement Obligation owing to such Lender Party from time to time, including the amounts of principal and interest payable and paid to such Lender Party from time to time hereunder. Entries made in good faith by such Lender Party in such account or accounts shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from the Borrower to such Lender Party under this Agreement and the Letter Agreement, absent manifest error; provided, however, that the failure of such Lender Party to make an entry, or any finding that an entry is incorrect, in such account or accounts shall not limit or otherwise affect the obligations of the Borrower to such Lender Party under this Agreement and the Letter Agreement.

MSCG will provide to Borrower within ten Bank Business Days after the end of each month a statement of interest and fees accrued during such month pursuant to this Agreement and to the Letter Agreement.

Section I.14. Collateral Account

(i). (a) Upon each drawing under a Letter of Credit during the period from the Effective Date to the Amendment Condition Effective Date, (i) the Issuer shall notify the Borrower of such drawing in accordance with Section 9.02 and (ii) the Borrower shall, not later than 2:00 p.m. (New York City time) on the Bank Business Day next succeeding the day of such notification referred to in clause (i), pay into the Collateral Account cash in U.S. dollars in an amount which, when combined with the aggregate amount of cash maintained in the Collateral Account immediately prior to such payment, is equal to or greater than 103% of the aggregate amount of all Reimbursement Obligations after giving effect to such drawing.

(b)The Borrower shall pay into the Collateral Account cash in U.S. dollars in the amounts required to be paid, and at the times required to be paid therein, pursuant to Section 2.06(d)(ii)(B). Such amounts shall be maintained in the Collateral Account until such time as:

(i) the sum of (x) the aggregate principal amount of the Advances outstanding at such time plus (y) the aggregate principal amount of the Reimbursement Obligations at such time plus (z) the aggregate Available Amount in respect of all Letters of Credit at such time is less than the Credit Facility Available Amount; and

(ii)the Borrower shall have delivered a written request to the Collateral Agent in accordance with Section 9.02, requesting a refund from the Collateral Account of the amount by which the Credit Facility Available Amount exceeds the sum of (x) the aggregate principal amount of the Advances outstanding at such time plus (y) the aggregate principal amount of the Reimbursement Obligations at such time plus (z) the aggregate Available Amount in respect of all Letters of Credit at such time,

whereupon the Collateral Agent shall, within three Bank Business Days of receipt of such written request, pay such amount into an account designated by the Borrower for such purpose; provided, however, that any such request for a refund shall be for an amount not less that $500,000 or an integral multiple thereof; and provided further, however, that anything to the contrary notwithstanding, the provisions of this Section 2.11(b) shall not affect the amounts required to be in the Collateral Account pursuant to Section 2.11(a).

(c)If, on any Bank Business Day, the Borrower is required to provide amounts both to the Collateral Agent pursuant to Section 2.11(a) and to the Paying Agent pursuant to Section 2.06(d), any amounts received by MSCG on such Bank Business Day shall be provided first to the Collateral Agent for application in accordance with Section 2.11(a), and any amounts remaining thereafter shall be provided to the Paying Agent to be applied in accordance with Section 2.06(d).

The Borrower agrees that, at any time and from time to time, at the expense of the Borrower, the Borrower will promptly execute and deliver all further instruments and documents, and take all further action that the Collateral Agent may reasonably request, in order to perfect and protect any security interest granted or purported to be granted hereby or to enable the Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, the Borrower will, upon the reasonable request of the Collateral Agent, (i) execute or authenticate and file such financing or continuation statements or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as the Collateral Agent may reasonably request, in order to perfect and preserve the security interests granted or purported to be granted hereby, (ii) take all action necessary to ensure that the Collateral Agent has control of Collateral consisting of deposit accounts and/or securities accounts as provided in Sections 9-104 and 9-106 of the UCC, and (iii) deliver to the Collateral Agent evidence that all other action that the Collateral Agent may deem reasonably necessary or desirable from time to time in order to perfect and protect the security interest created by the Borrower under this Agreement has been taken. The Borrower hereby authorizes the Collateral Agent to file one or more financing or continuation statements, and amendments thereto, relating to all or any part of the Collateral. The Borrower ratifies its authorization for the Collateral Agent to have filed such financing statements, continuation statements or amendments filed prior to the date hereof.

(a)The Borrower will not, without the prior written consent of the Collateral Agent (after having given the Collateral Agent not less than thirty days’ prior written notice thereof in accordance with Section 9.02 and after having executed and delivered to the Collateral Agent such further instruments and documents in connection therewith as may be reasonably requested by the Collateral Agent pursuant to this Section 7.05), change its jurisdiction of organization or its name.

(b)The Borrower shall defend the Collateral against all claims and demands of all Persons at any time claiming any interest therein that is, or in a manner which is, adverse to the Collateral Agent or any Lender Party.

(c)The Borrower shall not sell, lease, transfer, assign (by operation of law or otherwise) or otherwise dispose of, or grant any security interest in or option with respect to, directly or indirectly (or agree to any of the foregoing at any future time), all or any portion of the Collateral.

(d)The Borrower shall not deposit any funds in respect of, or proceeds from, any Collateral into any account other than the Collateral Account.

Section V.6. Collateral Agent Appointed Attorney-in-Fact

. The Borrower hereby irrevocably, upon the occurrence and during the continuation of any Default or Event of Default, appoints the Collateral Agent the Borrower’s attorney-in-fact, with full authority in the place and stead of the Borrower and in the name of the Borrower or otherwise, from time to time in the Collateral Agent’s discretion, to take any action and to execute any instrument that the Collateral Agent may deem necessary or advisable to accomplish the purposes of this Agreement (such power being coupled with an interest).

Section V.7. Collateral Agent May Perform

. If the Borrower fails to perform any agreement contained herein, the Collateral Agent may, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, if an Event of Default then exists; and the reasonable expenses of the Collateral Agent incurred in connection therewith shall be payable by the Borrower pursuant to Section 7.10.

Section V.8. Reasonable Care

. The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. The Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which an ordinary person accords its own property, it being understood that none of the Collateral Agent or the Lender Parties shall have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any Collateral, other than, with respect to the Collateral Agent, (a) the safe custody of any Collateral in its possession, (b) the accounting for monies actually received by it under this Agreement and (c) the application of monies in accordance with this Agreement.

Section V.9. Remedies

. In the event that any Event of Default shall have occurred and be continuing, then:

(a)The Collateral Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC in effect in the State of New York (whether or not such UCC applies to the affected Collateral) and also may: (i) with notice as specified in the next succeeding sentence unless Article 9 of such UCC permits sale without notice, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Collateral Agent may deem commercially reasonable, and (ii) exercise any and all rights and remedies of the Borrower under or in connection with the Collateral, or otherwise in respect of the Collateral, including, without limitation, (A) any and all rights of the Borrower to demand or otherwise require payment of any amount in respect of the Collateral and (B) exercise all other rights and remedies with respect to the Collateral, including, without limitation, those set forth in Section 9-607 of such UCC. The Borrower agrees that at least ten days’ notice to the Borrower provided in accordance with Section 9.02, sent after the occurrence of an Event of Default, of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(b)Any cash held by or on behalf of the Collateral Agent and all cash proceeds received by or on behalf of the Collateral Agent in respect of any sale of, collection from, or other realization upon all or any part of the Collateral shall be applied by the Collateral Agent to reimburse the Collateral Agent and the Lender Parties for the Secured Obligations. Any surplus of such cash or cash proceeds held by or on the behalf of the Collateral Agent and remaining after reimbursement in full of all the Secured Obligations shall be paid over to the Borrower or to whomsoever may be lawfully entitled to receive such surplus.

(c)All payments received by the Borrower in respect of the Collateral shall be received in trust for the benefit of the Collateral Agent, shall be segregated from other funds of the Borrower and shall be forthwith paid over to the Collateral Agent in the same form as so received (with any necessary endorsement).

(d)The Collateral Agent may, without notice to the Borrower except as required by law and at any time or from time to time, charge, set off and otherwise apply all or any part of the Secured Obligations against any funds held with respect to the Collateral or in any other deposit account.

Section V.10. Indemnity and Expenses

. The Borrower agrees to indemnify, defend and save and hold harmless the Collateral Agent and each Lender Party and their respective officers, directors, employees, agents and advisors (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or resulting from this Agreement or the Collateral (including, without limitation, enforcement of this Agreement), except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party’s gross negligence or willful misconduct.

(a)The Borrower will upon demand pay to the Collateral Agent the amount of any and all reasonable expenses, including, without limitation, the reasonable fees and expenses of its counsel and of any experts and agents, that the Collateral Agent may incur in connection with (i) the administration of this Article VII, (ii) the custody or preservation of, or the sale of, collection from or other realization upon, any of the Collateral, (iii) the exercise or enforcement of any of the rights of the Collateral Agent hereunder or (iv) the failure by the Borrower to perform or observe any of the provisions hereof.

Section V.11. Continuing Security Interest; Assignments

. This Article VII shall create a continuing security interest in the Collateral and shall (a) subject to Section 7.12, remain in full force and effect until the later of (i) the Termination Date and (ii) the date of payment in full, in cash, of the Secured Obligations, (b) be binding upon the Borrower and its successors and assigns and (c) inure, together with the rights and remedies of the Collateral Agent hereunder, to the benefit of the Lender Parties and their respective successors, transferees and assigns. Without limiting the generality of the foregoing clause (c), each Lender Party may assign or otherwise transfer all or a portion of its rights and obligations under this Agreement (including all or any portion of an Advance or Reimbursement Obligation held by it and all rights corresponding thereto under any of the Transaction Documents) to any other person to the extent permitted under Section 9.06, and such other person shall thereupon become vested with all the benefits in respect thereof granted to such Lender Party herein or otherwise, as provided in Section 9.06.

Section V.12. Release; Termination

. Upon the earlier of (a) the later of (i) payment in full, in cash, of the Secured Obligations then due and payable and (ii) the Termination Date and (b) the consummation of any sale or foreclosure in respect of any of the Collateral conducted by or under the direction of the Collateral Agent, the security interest granted by this Article VII shall automatically terminate and the Collateral shall automatically be released from such security interest but, in the case of the foregoing clause (b), only to the extent of the Collateral disposed of in such transaction, and only following the receipt by the Collateral Agent of the proceeds of such disposition, and the Collateral Agent, on behalf of the Lender Parties, shall enter into such documentation as may be reasonably requested by the purchaser of such Collateral and reasonably acceptable to the Collateral Agent in order to evidence such release. Upon the earlier date referred to in the first sentence, the Borrower shall be entitled to the return, upon its request and at its expense, of such of the Collateral as shall not have been sold or otherwise applied pursuant to the terms hereof and the Collateral Agent will, on behalf of the Lender Parties, enter into and deliver such documentation as shall be reasonably requested by the Borrower, and as may be reasonably acceptable to the Collateral Agent, to evidence such release, including UCC termination statements and such notices as the Borrower may reasonably request, at the Borrower’s expense, to evidence and confirm the release and discharge of the security interest granted by this Article VII. In the event that the Collateral Agent is required to refund any amounts to the Borrower pursuant to Section 2.11(b), the amounts that are so refunded shall automatically be released from the security interest granted by this Article VII and the Collateral Agent, on behalf of the Lender Parties, shall enter into such documentation as may be reasonably requested by the Borrower and reasonably acceptable to the Collateral Agent in order to evidence such release, all at the expense of the Borrower.

The Collateral Agent is hereby irrevocably authorized and instructed to enter into the other Transactions Documents to which it is intended to be a party. As to any matters requiring the exercise of discretion by the Collateral Agent, and not expressly requiring the consent of the Lender Parties, pursuant to the Transaction Documents (including enforcement of the Transaction Documents), the Collateral Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the written instructions of both Lender Parties; provided, however, that neither the Collateral Agent nor the Lender Parties shall be required to take an action that exposes such persons to personal liability or that is contrary to the Transaction Documents or applicable law. The Collateral Agent agrees to give to each Lender Party prompt notice of each notice and copies of all other documents given to it by the Borrower pursuant to the terms of this Agreement unless otherwise delivered by another party.

(b)The Collateral Agent may execute any of its duties under this Agreement or any other Transaction Document by or through agents, subagents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties.

Section VI.2. Collateral Agent’s Reliance, Etc

. Neither the Collateral Agent, nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by them under or in connection with the Transaction Documents, except for their own gross negligence or willful misconduct as finally determined by a court of competent jurisdiction. Without limiting the generality of the foregoing, the Collateral Agent (a) may treat each Lender Party as the holder of its interest in the Advances and the Reimbursement Obligations until it receives notice from the relevant Lender Party that such interest has been assigned; (b) may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the good faith advice of such counsel, accountants or experts; (c) does not make any warranty or representation to any Lender Party and shall not be responsible to any Lender Party for any statements, warranties or representations (whether written or oral) made by any person other than itself in or in connection with the Transaction Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of any Transaction Document on the part of the Borrower or any other party thereto or to inspect the property (including the books and records) of the Borrower; (e) shall not be responsible to any Lender Party for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of, any Lien or other interest created or purported to be created under, or in connection with, any Transaction Document; (f) shall incur no liability under or in respect of any Transaction Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by facsimile) believed by it to be genuine and signed or sent by the proper party or parties; (g) shall have no responsibility concerning the value or validity of the Collateral; and (h) may assume that no Default has occurred and is continuing unless it has, in its capacity as Collateral Agent, actual knowledge or actual notice to the contrary.

Section VI.3. Collateral Agent and Affiliates

. With respect to any interest in an Advance or a Reimbursement Obligation held by the Collateral Agent, the Collateral Agent shall have the same rights and powers under the Transaction Documents as any Lender Party and may exercise the same as though it were not the Collateral Agent, and the term “Lender Party” shall, unless otherwise expressly indicated, include the Collateral Agent in its individual capacity. The Collateral Agent and its affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of business with, the Borrower and/or any of its affiliates and any person who may do business with or own an interest in any of them, all as if it were not a Collateral Agent and without any duty to account therefor to any Lender Party.

Section VI.4. Lender Credit Decision

. Each of the Lender Parties acknowledges that it has, independently and without reliance upon the Collateral Agent or any other Lender Party or any affiliate thereof and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each of the Lender Parties also acknowledges that it will, independently and without reliance upon the Collateral Agent or any other Lender Party or affiliate thereof and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Transaction Documents.

Section VI.5. Successor Agents

. The Collateral Agent may resign at any time by giving not less than thirty Bank Business Days’ prior written notice to the Lender Parties, such resignation to be effective upon the appointment and acceptance of a successor Collateral Agent as provided for below. Upon any such resignation, the Lender Parties shall appoint a replacement Collateral Agent hereunder, subject (unless a Default or Event of Default is continuing) to the prior written consent of the Borrower (which consent may not be unreasonably withheld or delayed). Upon the acceptance of any appointment as Collateral Agent hereunder by a successor Collateral Agent and upon the execution and filing or recording of such instruments or notices as may be necessary or desirable or as the Lender Parties may reasonably request, in order to continue the perfection of the security interests granted or purported to be granted by the Transaction Documents, such successor Collateral Agent shall succeed to and become vested with all the rights, powers, discretion, privileges, duties and obligations of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations under the Transaction Documents. After any retiring Collateral Agent’s resignation hereunder as Collateral Agent, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Collateral Agent under this Agreement.

Section VI.6. Indemnification

. Each Lender Party shall, jointly and severally, indemnify, defend and save and hold harmless the Collateral Agent, its affiliates and their respective officers, directors, employees, agents and advisors (each, an “Indemnitee”) (to the extent not reimbursed by the Borrower) from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable and documented fees and expenses of counsel) that may be incurred by or asserted or awarded against such Indemnitee, in each case arising out of or in connection with or by reason of (including in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) an Advance, a letter of credit or a Reimbursement Obligation, the actual or proposed use of a letter of credit or the proceeds of an Advance, the Transaction Documents or any of the transactions contemplated thereby, including in connection with enforcement by such Indemnitee of its rights under this Section 8.06, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnitee’s bad faith, gross negligence or willful misconduct.

Section VII.3. No Waiver; Remedies

. No failure by any of the Lender Parties or the Collateral Agent to exercise, and no delay in exercising, any right under this Agreement shall operate as a waiver thereof; nor shall any single or partial exercise of any right under this Agreement preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

Section VII.4. Costs and Expenses; Indemnification

. (a) The Borrower agrees to pay on demand all reasonable costs and expenses of each Lender Party and the Collateral Agent in connection with the enforcement of the Transaction Documents, whether in any action, suit or litigation, or any bankruptcy, insolvency or other similar proceeding affecting creditors’ rights generally (including, without limitation, the reasonable fees and expenses of a single counsel for all Lender Parties and the Collateral Agent with respect thereto).

(b) The Borrower will indemnify and hold each Lender Party and its officers, directors, affiliates, employees, attorneys and agents (each, an “Indemnified Party”) harmless from and against any and all claims, liabilities, losses, damages, costs and expenses, including without limitation, reasonable attorneys’ fees and disbursements, other dispute resolution expenses (including fees and expenses in preparation for a defense of any investigation, litigation or proceeding) and costs of collection that arise out of or in connection with:

(i)the issuance of any Letter of Credit,

(ii)any payment or action taken or omitted to be taken in connection with any Letter of Credit (including any action or proceeding seeking (i) to restrain any drawing under such Letter of Credit, (ii) to compel or restrain the payment of any amount or the taking of any other action under such Letter of Credit, (iii) to compel or restrain the taking of any action under this Agreement, or (iv) to obtain similar relief (including by way of interpleader, declaratory judgment, attachment, or otherwise), regardless of who the prevailing party is in any such action or proceeding),

(iii)the enforcement of this Agreement, or

(iv)any act or omission, whether rightful or wrongful, of any present or future de jure or de facto government or governmental authority or any other cause beyond such Lender Party’s control,

Section VII.5. Binding Effect

. This Agreement shall, subject to the provisions of Section 3.01, become effective when it shall have been executed by the Borrower, the Lender Parties and the Collateral Agent and thereafter shall be binding upon and inure to the benefit of the Borrower, each Lender Party and the Collateral Agent and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of each Lender Party and the Collateral Agent.

Section VII.6. Assignments and Participations

. Each Lender Party may, with the prior written consent of the Borrower (which consent may not be unreasonably withheld or delayed) during any period in which no Default or Event of Default shall have occurred and be continuing, and upon the occurrence and during the continuance of any Default or Event of Default without any consent of or notice to the Borrower, assign to one or more assignees all or a portion of its rights (but not its obligations) under the Transaction Documents (including, without limitation, all or a portion of the Advances owing to it). Any such assignment that requires the prior written consent of the Borrower under this Section 9.06 but was made without such consent shall be void. For the avoidance of any doubt, the Issuer and Lender agree that any assignment permitted by this Agreement shall not relieve the Issuer and the Lender of their respective obligations hereunder.

(a). (a) When an Event of Default is continuing, any amount payable to the Borrower pursuant to either (i) this Agreement or the Letter Agreement and/or (ii) any other obligations between the Borrower and MSCG or any of its affiliates or instruments or undertakings issued or executed by MSCG or any of its affiliates to, or in favor of, the Borrower, will, at the option of MSCG, be reduced by its setoff against any amounts payable (whether at such time or in the future or upon the occurrence of a contingency) by the Borrower pursuant to either (i) this Agreement or the Letter Agreement or (ii) any other obligations between the Borrower and MSCG or any of its affiliates or instruments or undertakings issued or executed by the Borrower to, or in favor of, MSCG and any of its affiliates. The relevant Lender Party or Collateral Agent, as the case may be, will give notice to the Borrower in accordance with Section 9.02 of any setoff effected under this Section 9.07.

(b)For this purpose, any amounts set off under this Section 9.07 (or the relevant portion of such amount) may be converted by the relevant Lender Party or Collateral Agent into the currency in which the other is denominated at the rate of exchange at which such party would be able, acting in a reasonable manner and in good faith, to purchase the relevant amount of such currency.

(c)If an obligation is unascertained, the relevant Lender Party or Collateral Agent may in good faith estimate that obligation and setoff in respect of the estimate, subject to the relevant party accounting to the other when the obligation is ascertained.

(d)Nothing in this Section 9.07 shall be effective to create a security interest. This Section 9.07 shall be without prejudice and in addition to any right of setoff, combination of accounts, lien or other right to which any party is at any time otherwise entitled (whether by operation of law, contract or otherwise).

Section VII.8. Execution in Counterparts

. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

Section VII.9. No Liability of the Issuer

. The Borrower assumes all risks on the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuer nor any of its officers or directors shall be liable or responsible for: (a) the use that may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents, or of any endorsement(s) thereon, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged; or (c) payment by the Issuer against presentation of documents that do not comply with the terms of any Letter of Credit, including failure of any documents to bear any reference or adequate reference to any Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit, except only that the Borrower shall have a claim against the Issuer, and the Issuer shall be liable to the Borrower, to the extent of any direct, but not consequential, damages suffered by the Borrower that the Borrower proves were caused by the Issuer’s failure to exercise reasonable care when determining whether a draft and other document presented under any Letter of Credit appear, on their face, to be in strict compliance with the terms and conditions thereof, in accordance with, and to the extent set forth in, Section 9.09, the UCP or ISP98 (in either case, as applicable to such Letter of Credit), and Article 5 of the UCC as in effect in the State of New York.

Section VII.10. Jurisdiction, Etc

. Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of any New York State court or Federal court of the United States of America sitting in the Borough of Manhattan, New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to the Transaction Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the fullest extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in the Transaction Documents shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement in the courts of any jurisdiction.

(a)Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to the Transaction Documents to which it is a party in any New York State or Federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(a) On any Bank Business Day, the Borrower may notify the Issuer, in accordance with Section 9.02, that it proposes to terminate either (x) this Agreement in accordance with subsection (c)(i) below or (y) a specified unused portion of the Facilities in accordance with subsection (c)(ii) below, on a Bank Business Day (the “Proposed Termination Date”) which is at least five Bank Business Days after such notice is given (such notice being the “Proposed Termination Notice”).

After the Borrower shall send to the Issuer the Proposed Termination Noticed pursuant to subsection (a) above, the Issuer will, on the Bank Business Day before any Proposed Termination Date, notify the Borrower, in accordance with Section 9.02, of the amount of the Termination Fee which would be payable on the Proposed Termination Date if this Agreement, or a specified portion of the Facilities, is then terminated as specified in the Proposed Termination Notice, which notice by the Issuer shall set forth the calculation of such Termination Fee in reasonable detail.

UNCONDITIONAL AND IRREVOCABLE GUARANTEE OF ▇▇▇▇▇▇ ▇▇▇▇▇▇▇

To:	Counterparty

Ladies and Gentlemen:

We, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, a Delaware corporation hereby unconditionally and irrevocably guarantee to you, as primary obligor and not merely as surety, the due and punctual payment by MS Entity (together with its successors and permitted assigns, the “Guaranteed Party”) of any and all sums of money (subject solely to the limit referred to below) which may from time to time be due by the Guaranteed Party to you under the Irrevocable Letter of Credit [No. XXX] (as amended, supplemented or restated from time to time, the “Letter of Credit”) issued pursuant to the [Agreement] among [Counterparty] and the Guaranteed Party dated as of __________ __, 2007 (as amended, supplemented or restated from time to time, the “X Agreement”), and we undertake to pay to you upon demand all such sums which may from time to time be owing to you by the Guaranteed Party under such Letter of Credit but which are unpaid. ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ hereby agrees that we shall pay all reasonable costs, fees and expenses (including reasonable attorneys' fees and disbursements) incurred by you in successfully enforcing our obligations under this guarantee. This guarantee is a guarantee of payment and not of collectibility.

This guarantee will also unconditionally and irrevocably guarantee to you (on the same terms as set forth herein), as primary obligor and not merely as surety (but without duplication), the due and punctual payment by any affiliated entity of the Guaranteed Party of any and all sums of money which may from time to time be due by the such affiliated entity as obligor under a letter of credit issued in replacement of the Letter of Credit in accordance with the terms of the Reimbursement Agreement.

It is understood that our total liability in respect of this guarantee at any date shall not exceed [$ amount] payable to you under the Letter of Credit; provided that such total liability shall not on any date exceed the amount available for drawing under the Letter of Credit on such date plus any costs, fees and expenses payable hereunder.

We agree that our obligations hereunder with respect to the Letter of Credit shall be unconditional and will not be discharged except by complete payment of the amounts payable under such Letter of Credit, irrespective of any claim as to the Letter of Credit’s validity, regularity or enforceability, or the lack of authority of the Guaranteed Party to execute or deliver the Letter of Credit; or any change in or amendment to the Letter of Credit; or any waiver or consent by you with respect to any provisions thereof; or the absence of any action to enforce the Letter of Credit, or the recovery of any judgment against the Guaranteed Party or of any action to enforce a judgment against the Guaranteed Party under the Letter of Credit; or any similar circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor generally.

We waive diligence, presentment, demand on the Guaranteed Party for payment or otherwise (except as provided hereinabove), filing of claims, requirement of a prior proceeding against the Guaranteed Party and protest or notice, except as provided for in the Letter of Credit with respect to amounts payable by the Guaranteed Party thereunder. If at any time payment under the Letter of Credit is rescinded or must be otherwise restored or returned by you upon the insolvency, bankruptcy or reorganization of the Guaranteed Party or otherwise, our obligations hereunder with respect to such payment shall be reinstated upon such restoration or return being made by you.

We represent to you as of the date hereof that:

1.	we are duly organized and validly existing under the laws of the jurisdiction of our incorporation and have full power and legal right to execute and deliver this guarantee and to perform the provisions of this guarantee on our part to be performed;

2.	the execution, delivery and performance of this guarantee have been and remain duly authorized by all necessary corporate action and do not contravene any provision of our certificate of incorporation or by-laws or any law, regulation or contractual restriction binding on us or our assets;

all consents, authorizations, approvals and clearances (including, without limitation, any necessary exchange control approval) and notifications, reports and registrations requisite for the due execution, delivery and performance of this guarantee have been obtained from or, as the case may be, filed with the relevant governmental authorities having jurisdiction and remain in full force and effect and all conditions thereof have been duly complied with and no other action by, and no notice to or filing with, any governmental authority having jurisdiction is required for such execution, delivery or performance; and

this guarantee is legal, valid and binding obligation enforceable against us in accordance with its terms except as enforcement hereof may be limited by applicable bankruptcy, insolvency, reorganization or other similar laws affecting the enforcement of creditors' rights or by general equity principles.

So long as no amount is then due but unpaid under the Letter of Credit or this guarantee, this guarantee shall expire simultaneously with the termination of the Letter of Credit in accordance with its terms. This guarantee shall be automatically extended when the Letter of Credit is extended.

This guarantee shall be governed by and construed in accordance with the laws of the State of New York.

Sincerely,

▇▇▇▇▇▇ ▇▇▇▇▇▇▇
