By delivering a continuation/conversion notice (“Continuation/Conversion Notice”) to the Agent on or before 1:00 p.m., New York time, on a Business Day, the Borrower Agent may from time to time irrevocably elect, on not less than two (2) Business Days’ notice, that all, or any portion in an aggregate minimum amount of One Hundred Thousand Dollars ($100,000.00) with integral multiples of Fifty Thousand Dollars ($50,000.00) of any LIBOR Rate Loan be converted on the last day of an Interest Period into a LIBOR Rate Loan with a different Interest Period, or continued on the last day of an Interest Period as a LIBOR Rate Loan with a similar Interest Period, provided, however, that no portion of the outstanding principal amount of any LIBOR Rate Loans may be converted to, or continued as, LIBOR Rate Loans when any Default or Event of Default has occurred and is continuing, and no portion of the outstanding principal amount of any LIBOR Rate Loans may be converted to LIBOR Rate Loans of a different duration if such LIBOR Rate Loans relate to any Hedging Obligations related to any Hedging Contracts with respect to interest rates. In the absence of delivery of a continuation/conversion notice with respect to any LIBOR Rate Loan at least two Business Days before the last day of the then current Interest Period with respect thereto, such LIBOR Rate Loan shall, on such last day, automatically convert to a Revolving Loan that accrues interest by reference to the Prime Rate.

(c) Prime Rate Loan. Lenders shall not be required to make a Prime Rate Loan unless Agent shall have received from the Borrower Agent a request for such Prime Rate Loan (the “Prime Loan Notice of Borrowing”).

26 request, a Revolving Loan Advance in a minimum amount of Ten Thousand ($10,000.00) Dollars with integral multiples of Ten Thousand ($10,000.00) Dollars. On the terms and subject to the conditions of this Agreement, each Prime Rate Loan shall be made available to the Borrowers no later than 3:00 p.m. New York time on the effective date specified therefore by deposit to the account of the Borrowers as shall have been specified in its borrowing request. For purposes herein, each of the LIBOR Notice of Borrowing, the Continuation/Conversion Notice and a Prime Loan Notice of Borrowing may be referred to as “Notice of Borrowing”)

(d) Certification. Upon delivery of a Notice of Borrowing, Borrowers shall be deemed to have certified that no Default or Event of Default shall have occurred and be continuing or created as a result of the borrowing being requested and all representations and warranties contained herein and in all of the Other Loan Documents are true and complete in all material respects, except to the extent such representation and warranty relates to an earlier date, and in such case, the representation and warranties are true and correct in all material respects as of such date of said Notice of Borrowing; additionally, upon request by the Agent, the Borrower Agent shall deliver to Agent a completed Borrower’s Certificate in substantially the form of Exhibit 2 attached hereto and made a part hereof.

(a) Repayments, Continuations and Conversions. LIBOR Rate Loans shall mature and become payable in full on the last day of the Interest Period relating to such LIBOR Rate Loan. Prior to the termination of this Agreement, upon maturity of any LIBOR Rate Loan, such Revolving Loan may be continued for an additional Interest Period or may be converted to a Prime Rate Loan, as set forth above (unless there exists any Default or Event of Default and the Agent does not otherwise elect to exercise any right to accelerate the Loans it is granted hereunder).

(b) Voluntary Prepayment of LIBOR Rate Loans. LIBOR Rate Loans may be prepaid upon the terms and conditions set forth herein. For LIBOR Rate Loans in connection with which the Borrowers have or may incur Hedging Obligations, additional obligations may be associated with prepayment in accordance with the terms and conditions of the applicable Hedging Contracts. The Borrower Agent shall give the Agent, no later than 1:00 p.m., New York City time, at least two (2) Business Days notice of any proposed prepayment of any LIBOR Rate Loans, specifying the proposed date of payment of such LIBOR Rate Loans, and the principal amount to be paid.

Borrowers acknowledge that prepayment or acceleration of a LIBOR Rate Loan during an Interest Period shall result in the Agent incurring additional costs, expenses and/or liabilities and that it is extremely difficult and impractical to ascertain the extent of such costs, expenses and/or liabilities. Therefore, all full or partial prepayments of LIBOR Rate Loans shall be accompanied by, and the Borrowers hereby promise to pay, on each date a LIBOR Rate Loan is prepaid or the date all sums payable hereunder become due and payable, by acceleration or otherwise, in addition to all other sums then owing, an amount (“LIBOR Rate Loan Prepayment Fee”) determined by the Agent pursuant to the following formula:

Except as expressly provided herein, all payments (including prepayments) to be made by Borrowers on account of principal, interest and fees shall be made when due without set off or counterclaim and shall be made to Agent on behalf of the Lenders to the Payment Office, in each case on or prior to 1:00 P.M., New York time, in Dollars and in immediately available funds.

(c) (i) Commencing with the first Business Day following the Closing Date, each borrowing of Revolving Loans shall be advanced by Agent and each payment by Borrowers on account of Revolving Loans shall be applied to those Revolving Loans advanced by Agent. On or before 1:00 p.m., New York time, on each Settlement Date commencing with the first Settlement Date following the Closing Date, Agent and Lenders shall make certain payments as follows: (I) if the aggregate amount of new Revolving Loans made by Agent during the preceding Week (if any) exceeds the aggregate amount of repayments applied to outstanding Revolving Loans during such preceding Week, then each Lender shall provide Agent with funds in an amount equal to its applicable Commitment Percentage of the difference between (w) such Revolving Loans and (x) such repayments and (II) if the aggregate amount of repayments applied to outstanding Revolving Loans during such Week exceeds the aggregate amount of new Revolving Loans made during such Week, then Agent shall provide each Lender with funds in an amount equal to its applicable Commitment Percentage of the difference between (y) such repayments and (z) such Revolving Loans.

(ii) Each Lender shall be entitled to earn interest at the applicable interest rate(s) hereunder on outstanding advances which it has funded.

(iii) Promptly, but not later than the end of each week, following each Settlement Date, Agent shall submit to each Lender a certificate with respect to payments received and advances made during the Week immediately preceding such Settlement Date. Such certificate of Agent shall be conclusive in the absence of manifest error.

(d) If any Lender (a “Benefited Lender”) shall at any time receive any payment of all or part of its advances, or interest thereon, or receive any Collateral in respect thereof (whether voluntarily or involuntarily or by set-off) in a greater proportion than any such payment to and Collateral received by any other Lender, if any, in respect of such other Lender’s advances, or interest thereon, and such greater proportionate payment

33 or receipt of Collateral is not expressly permitted hereunder, such benefited Lender shall purchase for cash from the other Lenders a participation in such portion of each such other Lender’s advances, or shall provide such other Lender with the benefits of any such Collateral, or the proceeds thereof, as shall be necessary to cause such benefited Lender to share the excess payment or benefits of such Collateral or proceeds ratably with each of the other Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. Each Lender so purchasing a portion of another Lender’s advances may exercise all rights of payment (including, without limitation, rights of set-off) with respect to such portion as fully as if such Lender were the direct holder of such portion.

(e) Unless Agent shall have been notified by telephone, confirmed in writing, by any Lender that such Lender will not make the amount which would constitute its applicable Commitment Percentage of the advances available to Agent, Agent may (but shall not be obligated to) assume that such Lender shall make such amount available to Agent on the next Settlement Date and, in reliance upon such assumption, make available to Borrowers a corresponding amount. Agent will promptly notify Borrower Agent of its receipt of any such notice from a Lender. If such amount is made available to Agent on a date after such next Settlement Date, such Lender shall pay to Agent on demand an amount equal to the product of (i) the daily average Federal Funds Effective Rate (computed on the basis of a year of 360 days) during such period as quoted by Agent, times (ii) such amount, times (iii) the number of days from and including such Settlement Date to the date on which such amount becomes immediately available to Agent. A certificate of Agent submitted to any Lender with respect to any amounts owing under this Section 5(V)(e) shall be conclusive, in the absence of manifest error. If such amount is not in fact made available to Agent by such Lender within three (3) Business Days after such Settlement Date, Agent shall be entitled to recover such an amount, with interest thereon at the rate per annum then applicable to such Revolving Loans hereunder, within five (5) days from demand of Borrower Agent; provided, however, that Agent’s right to such recovery shall not prejudice or otherwise adversely affect Borrowers’ rights (if any) against such Lender.

(f) Notwithstanding anything to the contrary contained herein, in the event any Lender (x) has refused (which refusal constitutes a breach by such Lender of its obligations under this Agreement) to make available its portion of any Revolving Loan or (y) notifies either Agent or Borrower Agent that it does not intend to make available its portion of any Revolving Loan (if the actual refusal would constitute a breach by such Lender of its obligations under this Agreement) (each, a “Lender Default”), all rights and obligations hereunder of such Lender (a “Defaulting Lender”) as to which a Lender Default is in effect and of the other parties hereto shall be modified to the extent of the express provisions of this Section while such Lender Default remains in effect.

(g) Advances shall be made pro rata from Lenders (the “Non-Defaulting Lenders”) which are not Defaulting Lenders based on their respective Commitment Percentages, and no Commitment Percentage of any Lender or any pro rata

34 share of any advance required to be advanced by any Lender shall be increased as a result of such Lender Default. Amounts received in respect of principal of any type of Advances shall be applied to reduce the applicable advances of each Lender pro rata based on the aggregate of the outstanding Revolving Loans of that type of all Lenders at the time of such application; provided, that, such amount shall not be applied to any advances of a Defaulting Lender at any time when, and to the extent that, the aggregate amount of advances of any Non-Defaulting Lender exceeds such Non-Defaulting Lender’s Commitment Percentage of all Revolving Loans then outstanding.

(h) A Defaulting Lender shall not be entitled to give instructions to Agent or to approve, disapprove, consent to or vote on any matters relating to this Agreement and the Other Documents. All amendments, waivers and other modifications of this Agreement and the Other Documents may be made without regard to a Defaulting Lender and, for purposes of the definition of “Required Lenders”, a Defaulting Lender shall be deemed not to be a Lender and not to have Advances outstanding.

(i) Other than as expressly set forth in this Section, the rights and obligations of a Defaulting Lender (including the obligation to indemnify Agent) and the other parties hereto shall remain unchanged. Nothing in this Section shall be deemed to release any Defaulting Lender from its obligations under this Agreement and the Other Documents, shall alter such obligations, shall operate as a waiver of any default by such Defaulting Lender hereunder, or shall prejudice any rights which Borrowers, Agent or any Lender may have against any Defaulting Lender as a result of any default by such Defaulting Lender hereunder.

(j) In the event a Defaulting Lender retroactively cures to the satisfaction of Agent the breach which caused a Lender to become a Defaulting Lender within five (5) Business Days from the date of the breach, such Defaulting Lender shall no longer be a Defaulting Lender and shall be treated as a Lender under this Agreement. If, however, a breach is not cured as provided herein, or in the event that a former Defaulting Lender (which such Lender previously cured such default as provided herein), fails on another occasion to make available its pro rata share of any Revolving Loan (whether or not cured), then, provided Borrowers are not then in Default hereunder, Borrowers shall have the right to require the Agent to exercise the repurchase rights contained in Section 5(V)(k), below with respect to any Defaulting Lender.

(k) The Agent shall, upon request of Borrower Agent pursuant to subsection (j) above, and provided there exists no Default hereunder, require any Defaulting Lender other than Citizens Bank New Hampshire to assign its interest in the Revolving Loan to Citizens Bank New Hampshire or to any other Lender or to any other Person designated by the Agent (“Designated Lender”), for a price equal to the then outstanding principal amount plus accrued interest and unpaid interest and fees due such Lender. Upon payment to such Lender in the amount of the then outstanding principal amount of Lender’s Commitment Percentage of the outstanding Revolving Loans, plus accrued and unpaid interest due such Lender, such Lender will assign its interest to Citizens Bank New Hampshire or the Designated Lender, as applicable, pursuant to a

35 Commitment Transfer Supplement executed by such Lender, Citizens Bank New Hampshire or the Designated Lender, as appropriate and Agent substantially in the form of Exhibit 5 attached hereto.

(l) No Defaulting Lender shall be entitled to receive any fees with respect to their Commitment Amount, Revolving Loans or participation in Letters of Credit while such Lender is a Defaulting Lender hereunder, provided however, that the Non-Defaulting Lenders shall be entitled to such fees and Borrowers shall pay to the Agent, for the benefit of the Non-Defaulting Lenders, such amounts as shall be due and owing hereunder.

(a) LIBOR Rate Lending Unlawful. If after the Closing Date, the Agent (or any Lender) shall determine (which determination shall, upon notice thereof to the Borrower Agent be conclusive and binding on the Borrowers) that the introduction of or any change in or in the interpretation of any law, rule or regulation, makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for the Agent (or any Lender) to make, continue or maintain any LIBOR Rate Loan as, or to convert any Revolving Loan into, a LIBOR Rate Loan of a certain duration, all existing LIBOR Rate Loans of such type shall automatically convert into LIBOR-Reference Banks Loans at the end of the then current Interest Periods with respect thereto or sooner, if required by such law or assertion. For purposes of this agreement, in the event of such a conversion, all LIBOR-Reference Banks Rate Loans shall be treated (except as to interest rate) as equivalent to a LIBOR Rate Loan of similar amount and Interest Period. For greater certainty, all provisions of this agreement relating to LIBOR Rate Loans shall apply equally to LIBOR-Reference Banks Loans, including, but not limited to the manner in which LIBOR-Reference Banks Rate Loans are requested, continued, converted, the manner in which interest accrues, is payable, principal payments are made, whether voluntary or involuntary, as well as any penalties, increased costs or taxes associated with any of the foregoing.

(b) Substitute Rate. If the Agent (or any Lender) shall have determined after the Closing Date that:

(c) Indemnities. In addition to the LIBOR Rate Loan Prepayment Fee, the Borrowers agree to reimburse the Agent (or any Lender) (without duplication to such amounts already included in the calculation of LIBOR Rate Loan Prepayment Fee) within ten (10) Business Days for any increase in the cost to the Agent (or any Lender), or reduction in the amount of any sum receivable by the Agent (or any Lender), in respect, or as a result of:

(d) Increased Costs. If on or after the date hereof the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Agent (or any Lender) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency after the Closing Date:

(e) [Reserved.]

(f) Taxes. All payments by the Borrowers of principal of, and interest on, the LIBOR Rate Loans and all other amounts payable hereunder shall be made free and clear

38 of and without deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by the Agent’s (or any Lender’s) net income or receipts (such non-excluded items being called “Taxes”). In the event that any withholding or deduction from any payment to be made by the Borrowers hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then the Borrowers will

(g) Notwithstanding anything to the contrary contained herein, Agent and Borrowers agree that after the occurrence of an Event of Default which is continuing, Borrowers shall not request and Agent will not make LIBOR Rate Loans.

(h) In addition to all other sums payable hereunder, Borrowers shall pay Agent for the ratable benefit of the Lenders, a fee (the “Unused Line Fee”) in an amount equal to one-fifth of one percent (.20%) per annum of the difference between: (i) the Credit Limit and (ii) the average amount of the principal balance of Revolving Loans outstanding for each quarterly period this Agreement is in effect, plus the average amount of Outstanding Letters of Credit. Such Unused Line Fee shall be payable quarterly in arrears and shall be treated as a Revolving Loan to Borrowers for working capital purposes. The Unused Line Fee shall be divided pro rata amount the Lenders in accordance with their respective Commitment Percentages.

39 (i) In addition to all other sums payable hereunder, Borrowers shall pay to Agent (i) an Administrative Agent fee equal to Ten Thousand and 00/100 Dollars ($10,000.00) per annum, payable quarterly in advance, provided that there is more than one Lender a party to this Agreement; in the event that more than two Lenders are party to this Agreement, an additional fee of Five Thousand and 00/100 Dollars ($5,000.00) per annum per additional Lender shall be due and payable quarterly by the Borrowers; (ii) an origination fee equal to one fifth of one percent (.20%) of the maximum Credit Limit, or One Hundred Twenty Thousand and 00/100 Dollars ($120,000.00), of which the Agent has received $30,000.00, which such amount shall not be shared with any other Lenders, and the balance of Ninety Thousand Dollars ($90,000.00) shall be payable in full on the Closing Date. Said Ninety Thousand Dollar ($90,000.00) shall be shared for the ratable benefit of the Lenders, based upon each such Lender’s Commitment Percentage and the time remaining in the initial Term at the time such Lender becomes a party to this Agreement. Each Lender acknowledges and agrees that the aforementioned Thirty Thousand and 00/100 Dollars ($30,000.00) received by Agent with respect to the origination fee, “float day” interest and all administrative fees and account fees payable by Borrowers to Agent hereunder shall be payable by Agent to Citizens and shall not be shared with any other Lenders, except in the event Agent is not the Issuing Lender, in which case the Issuing Lender will be entitled to retain administration fees related to such issuance. Any administrative and account fees incurred in connection with the issuance of any Letters of Credit hereunder and payable by Borrowers to Agent hereunder shall be payable by Agent to the Issuing Lender and shall not be shared with any other Lenders. The Unused Line Fee and all LC Commissions shall be payable by Borrowers to Agent hereunder and shall be thereafter shared for the ratable benefit of the Lenders.

(a) The obligation of the Lenders to make the initial Revolving Loan hereunder or issue or cause to be issued any Letter of Credit hereunder on the Closing Date to the Borrowers shall be subject to the condition precedent that Agent for itself and the benefit of the Lenders shall have received all of the following, each in form and substance reasonably satisfactory to Agent:

(b) Notwithstanding anything to the contrary contained in this Agreement, Borrowers acknowledge that no Revolving Loans shall be made or Letter of Credit issued until such time as (i) all SVB Liens have been released and Agent has filed all UCC financing statements required to be filed to perfect its security interests in the Collateral, and Agent has received confirmation thereof, satisfactory to the Agent in its sole discretion, and (ii) the Borrowers have delivered a compliance certificate as of the month ended March 30, 2007.

(c) The obligation of the Lenders to make each Revolving Loan shall be subject to satisfaction or waiver of the further conditions precedent on such date:

(a) All proceeds received on account of the Obligations shall be applied by the Agent in the following order:

First, to payment of that portion of the Obligations (excluding Hedging Obligations) constituting fees, indemnities, expenses and other amounts including without limitation, fees, charges and disbursements of counsel to the Agent payable under this Agreement, including out-of-pocket expenses of Agent incurred under any Other Documents, or in connection with the realization of any Collateral, including without limitation, reasonable expenses of retaking, holding, preparing for sale, selling and the like incurred by Agent, as Mortgagee under the Mortgage, including reasonable attorneys’ fees and out-of-pocket legal expenses, the expense of insurance, the expense of ordinary or extraordinary repairs or alterations deemed necessary by Agent, as Mortgage, the expense of taxes or other charges on the Mortgaged Property (as defined in the Mortgage) which Agent, as Mortgagee may deem it wise to pay, together with reserves for the foregoing to the extent deemed necessary by Agent, as Mortgagee) shall be paid to the Agent, as Mortgagee for application against all sums due and owing to Mortgagee or any Lender payable to the Agent.

Agent will credit (conditional upon final collection) all such payments against the principal or interest of any Revolving Loans secured hereby as set forth above; provided, however, for the purpose of computing interest, any items requiring clearance or payment shall not be considered to have been credited against any Revolving Loans secured hereby until two (2) Business Days after receipt by Agent of any such items and any surplus remaining after payment of outstanding Obligations shall be remitted to Borrowers, provided however, that any wire transfers received by the Agent prior to 1:00pm on any Business Day will be credited on that day, and any such wire transfers received by the Agent after 1:00pm on any Business Day shall be credited on the next Business Day. As provided in Section 11(c), below, Agent will at all times have the right to require Borrowers to maintain its primary deposit accounts at Agent or, in the alternative, at the Agent’s option, at another financial institution subject to a Control Agreement such that, among other things, during the continuance of an Event of Default, Borrowers’ account shall be blocked and such institution shall have waived its rights as against such account. Agent shall also, during the continuance of an Event of Default, have the right to require Borrowers to enter into a lockbox arrangement with Agent for the collection of such remittances and payments and the Borrowers shall use all diligent efforts to effectuate such arrangements as soon as reasonably practicable. Notwithstanding anything contained to the contrary herein, said proceeds shall not be applied to the principal of any LIBOR Rate Loan(s), until all Prime Rate Loans have been paid in full and the application of proceeds shall not be considered a prepayment given rise to any related fees (other than any applicable LIBOR Rate Loan Prepayment Fee, if any).

(b) To the extent permitted by applicable law, each Borrower hereby grants to Agent and each Lender a Lien, security interest and right of setoff as security for all Obligations to Agent and each Lender, whether now existing or hereafter arising, upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Agent or any entity in the control of the Agent, or any Lender, (other

45 than Excluded Deposits, as defined in Section 11(c), below). At any time during the continuance of an Event of Default, without demand or notice, Agent may set off the same or any part thereof and apply the same to any Obligation of the Borrowers even though unmatured and regardless of the adequacy of any other Collateral securing the Obligations. Additionally, at any time there is a draw on any Letter of Credit, then, without demand or notice, Agent may treat such amount as a Revolving Loan under this Agreement for working capital purposes. ANY AND ALL RIGHTS TO REQUIRE AGENT TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWERS, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED TO THE EXTENT PERMITTED BY APPLICABLE LAW.

(c) The Borrowers shall at all times maintain the Agent, as their principal depository bank. For each deposit account that each Borrower at any time opens or maintains that is not with Agent (as may be permitted hereunder), such Borrower shall, at Agent’s request and option, arrange for execution of a control or other similar type agreement by and among Agent, the applicable Borrowers and applicable depository bank in form and substance acceptable to Agent in its sole discretion, which such agreement among other things, either (i) causes the depository bank to agree to comply at any time with instructions from Agent to such depository bank directing the disposition of funds from time to time credited to such deposit account, without further consent of any such Borrower, and cause such depository bank to acknowledge that any Lien held by such depository bank on such accounts is subordinate to the Liens of the Lenders, or (ii) arranges for the Agent to become the customer of the depository bank with respect to the deposit account, with such Borrowers being permitted, only with the consent of Agent, to exercise rights to withdraw funds from such deposit account (the “Control Agreement(s)”). Agent agrees with Borrowers that Agent shall not give any such instructions or withhold any withdrawal rights from Borrowers, unless an Event of Default has occurred and is continuing, or after giving effect to any withdrawal not otherwise permitted by this Agreement an Event of Default would occur. The Agent agrees to rescind any such instructions within ten (10) Business Days of any such Event of Default being curerd or waived. In no event shall Borrowers fail to maintain deposit accounts with Agent in a minimum amount of the lesser of (i) the total amount of Letters of Credit issued by Agent (or any Lender); or (ii) 100% of Borrowers’ deposit accounts (the “Mininum Deposit”). Notwithstanding anything to the contrary contained herein, Borrowers shall not maintain any deposit accounts with any bank, institution or other party other than a Lender, except (x) for any overseas deposit accounts in any country where there is no local branch network of any Lender and in such case Borrowers shall provide Agent with such account information and statements and otherwise comply with Section 11(c)(i) or (ii), above, and (y) that Borrowers shall be allowed to maintain deposit accounts with any other financial institution similar to Agent or Lenders only in the event that Agent (and/or any applicable Lender) is unable to provide competitive market returns on such deposit investments, and in such events, only to the extent that such deposits allowed under Section 11(c)(x) and (y), above, exceed the Minimum Deposit requirements set forth in this Section 11(c), above, and further, in such case Borrowers shall provide Agent with such account information and statements and otherwise comply with Section 11(c)(i) or (ii), above. Additionally, the Agent shall at all times have the right to control any such deposit accounts through Control

46 Agreements, blocked accounts or such other similar arrangements with the Borrowers. Notwithstanding anything to the contrary contained herein, the provisions of this paragraph shall not apply to (xx) any deposit account for which Borrowers, the depository bank and Agent have entered into a cash collateral agreement specially negotiated among Borrowers, the depository bank and Agent for the specific purpose set forth therein, or (yy) deposit accounts specifically and exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of any Borrower’s salaried employees and ▇▇▇▇▇ cash (collectively, the “Excluded Deposit Accounts”).

(d) The Agent may at any time, during the continuance of an Event of Default, and with two (2) Business Days prior notice to the Borrower Agent, notify account debtors that Collateral has been collaterally assigned to Agent and that payments shall be made directly to or as directed by Agent. Upon request of Agent at any time during the continuance of an Event of Default, the Borrowers will so notify such account debtors and will indicate on all ▇▇▇▇▇▇▇▇ to such account debtors that their Accounts must be paid directly to or as directed by the Agent.

(e) The Borrowers shall pay to Agent within fifteen (15) days of written demand therefor any and all reasonable counsel fees and other reasonable actual out-of-pocket expenses incurred by Agent (or any of the Lenders with respect to enforcement) in connection with the preparation, interpretation, enforcement, administration or amendment of this Agreement, the Notes and the Other Documents or of any documents relating thereto, and any and all expenses, including, but not limited to, a collection charge on all Accounts collected, all attorneys’ fees for the Agent and out-of-pocket expenses, and all other expenses of like or unlike nature which may be expended by Agent or any Lender to obtain or enforce payment of any Account either as against the account debtor, Borrowers, or any Guarantor or surety of Borrowers or in the prosecution or defense of any action or concerning any matter growing out of or connected with the subject matter of this Agreement, including protection of the security interests or the priority thereof, the Obligations or the Collateral or any rights or interests therein or thereto of Agent or the Lenders, including, without limiting the generality of the foregoing, any counsel fees or expenses incurred in any bankruptcy or insolvency proceedings and all costs and expenses incurred or paid by Agent or any Lender in connection with the administration, supervision, protection or realization on any security held by Agent for the debt secured hereby, whether such security was granted by any Borrower or by any other person primarily or secondarily liable (with or without recourse) with respect to such debt, and all costs and expenses incurred by Agent (or any Lender) in connection with the defense, settlement or satisfaction of any action, claim or demand asserted against Agent in connection with the debt secured hereby, all of which amounts shall be considered advances to protect Agent’s security, and shall be secured hereby. Additionally, at its option, and without limiting any other rights or remedies, with five (5) days prior notice to the Borrower Agent the Agent may at any time pay or discharge any taxes, Liens at any time levied against or placed on any of the Collateral, and may procure and pay any premiums on any insurance required to be carried by the Borrowers, and provide for the maintenance and preservation of any of the Collateral, and otherwise take any action reasonably deemed necessary to the Agent to protect its security, and all amounts expended by the Agent in connection with any of the foregoing matters, including reasonable attorneys’ fees for the Agent, shall be considered Obligations and shall be secured hereby. Agent shall use

47 reasonable efforts to provide Borrower Agent with documentation reasonably supporting such costs and expenses herein, with such written notice of demand therefore, but in any event shall provide any such supporting documentation, as applicable, as soon as reasonably practicable after such demand.

(f) The Borrowers do hereby make, constitute and appoint any officer or agent of Agent as Borrowers’ true and lawful attorney-in-fact, with power to endorse the name of the Borrowers or any of Borrower’s officers or agents upon any notes, checks, drafts, money orders, or other instruments of payment (including payments payable under any policy of insurance on the Collateral) or Collateral that may come into possession of Agent in full or part payment of any amounts owing to Agent; to sign and endorse the name of Borrowers or any of Borrowers’ officers or agents upon any invoice, freight or express ▇▇▇▇, ▇▇▇▇ of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications and notices in connection with Accounts, and any instrument or documents relating thereto or to Borrowers’ rights therein; collect, compromise, endorse, sell or otherwise deal with the Collateral or proceeds thereof in its own name or in the name of each Borrower; to give written notice to such office and officials of the United States Post Office to effect such change or changes of address so that all mail addressed to Borrowers may be delivered directly to Agent; granting upon Borrowers’ said attorney full power to do any and all things necessary to be done in and about the premises as fully and effectually as Borrowers might or could do, and hereby ratifying all that said attorney shall lawfully do or cause to be done by virtue hereof, provided however, that Agent shall not take any such actions unless an Event of Default shall have occurred and be continuing. Neither Agent nor the attorney shall be liable for any acts or omissions nor for any error of judgment or mistake, except for their gross negligence, willful misconduct, bad faith, or material breach of this Agreement or ther Other Documents. This power of attorney shall be irrevocable for the term of this Agreement and all transactions hereunder and thereafter as long as Borrowers may be indebted to Agent.

Said 10Q statements shall be in place of the monthly statement required hereunder only for such month in which each quarter closes.

(e) Borrowers will furnish Agent, annually, as soon as available, and in any event within one-hundred twenty (120) days after the end of each fiscal year of Borrowers, Borrowers’ audited consolidated financial statements with the unqualified opinion (excluding

(f) Borrower Agent will promptly, upon receipt thereof, deliver to Agent, copies of any reports submitted to any Borrower by the Borrowers’ independent public accountants in connection with the examination of the financial statements of the Borrowers made by such accountants (the so-called “Management Letter”).

(g) In addition to the foregoing, the Borrowers promptly shall provide Agent with such other and additional information concerning the Borrowers, the Collateral, the operation of the Borrowers’ business, and the Borrowers’ financial condition, including financial reports and statements, as Agent may from time to time reasonably request from the Borrowers.

Further notwithstanding any provision to the contary contained in this Agreement, no Borrower shall be allowed to transfer any assets to GT Holdings at any time except as allowed pursuant to Section 15(e), herein.

(a) Upon the occurrence of any one or more of the following events (herein, “Events of Default”), Agent, shall at the option and direction of the Required Lenders decline to make any or all further Revolving Loans or issue Letters of Credit hereunder and all Obligations of the Borrowers to Agent and Lenders shall become immediately due and payable, at the option of the Required Lenders and without notice or demand:

(b) Upon the filing of any complaint, application, or petition by or against the Borrowers initiating any matter in which the Borrowers are or may be granted any relief from the debts of the Borrowers pursuant to the Bankruptcy Code, Agent’s and each Lender’s obligations hereunder shall be terminated immediately, automatically, and without notice, and all Obligations of the Borrowers then outstanding shall become immediately due and payable without presentation, demand, or notice of any kind to the Borrowers.

(c) Any sale or other disposition of the Collateral may be at public or private sale upon such terms and in such manner as the Agent deems advisable, having due regard to compliance with any statute or regulation which might affect, limit or apply to the Agent’s disposition of the Collateral. Subject to the terms of any applicable leases, the Agent may conduct any such sale or other disposition of the Collateral upon the Borrowers’ premises. Unless the Collateral is perishable or threatens to decline speedily in value, or is of a type customarily sold on a recognized market (in which event the Agent shall provide the Borrower Agent with such notice as may be practicable under the

66 circumstances), the Agent shall give the Borrower Agent at least the greater of the minimum notice required by law or ten (10) days prior written notice of the date, time and place of any proposed public sale, and of the date after which any private sale or other disposition of the Collateral may be made. The Agent may purchase the Collateral, or any portion of it at any public sale.

If the purchaser fails to pay for the Collateral, the Agent may resell the Collateral and the Borrowers shall be credited with the proceeds of the sale.

(e) In connection with the Agent’s exercise of the Agent’s rights after the occurrence and during the continuance of an Event of Default, subject to the terms of any applicable lease, the Agent may enter upon, occupy and use any premises owned or occupied by any Borrower, and may exclude such Borrower from such premises or portion thereof as may have been so entered upon, occupied, or used by the Agent. The Agent shall not be required to remove any of the Collateral from any such premises upon the Agent’s taking possession thereof, and may render any Collateral unusable to the Borrowers. In no event shall the Agent be liable to any Borrower for use or occupancy by the Agent of any premises pursuant to this Agreement other than to the extent of the Agent’s (or its agent’s Officer’s, director’s or employee’s) gross negligence, bad faith or willful misconduct.

(f) Upon the occurrence and during the continuance of any Event of Default, the Agent at the direction of the Required Lenders may require the Borrowers to assemble the Collateral and make it available to the Agent at the Borrowers’ sole risk and expense at a place or places which are reasonably convenient to both the Agent and the Borrowers.

(a) Unless renewed in writing, this Agreement shall terminate on March 31, 2010 (the “Termination Date”), and all Obligations (including obligations to cash collateralize any outstanding Letters of Credit as set forth in Section 16(a) hereto, provided in any event, however, that any such outstanding Letters of Credit shall mature not more than six months following the Termination Date hereunder, as the same may be extended as provided herein) shall be due and payable in full, to the extent permitted by applicable law, without presentation, demand, or further notice of any kind, whether or not all or any part of the Obligations is otherwise due and payable pursuant to the agreement or instrument evidencing same. At the Borrowers’ request to be made annually not later than October 1, the Lenders may extend the Termination Date on an annual basis in their sole discretion, such that Borrowers may maintain a three (3) year facility at all times. In the event that the Lenders grant such extension in any year, the Agent shall provide written notice of such extension not later than March 31, but in any event as soon after receipt of fiscal year end statements, management letter and projections, as is practicable for the Lenders.

Agent, upon instruction of the Required Lenders, may terminate this Agreement immediately and without notice upon the occurrence of an Event of Default. Notwithstanding the foregoing or anything in this Agreement or elsewhere to the contrary, the security interest, Agent’s and Lenders’ rights and remedies hereunder and Borrowers’ obligations and liabilities hereunder shall survive any termination of this Agreement and shall remain in full force and effect until all of the Obligations outstanding, or contracted or committed for (whether or not outstanding), shall be finally and irrevocably paid in full.

Upon (a) the disposition of any Collateral in accordance with the terms of this Agreement (including application of proceeds therefrom as provided herein) or (b) final and irrevocable payment in full of the Obligations (other than the Hedging Contracts), the security interests granted herein shall automatically terminate with respect to (i) such Collateral (in the case of clause (a)) or (ii) all Collateral (in the case of clause (b)). Upon such payment in full of the Obligations, Agent will, at Borrowers’ sole expense, promptly deliver to Borrower Agent, all pledged Collateral held by the Agent hereunder, and execute and deliver to Borrower Agent such documents as Borrower Agent shall reasonably request to evidence such termination; provided, further, the Agent and Lenders agree that, upon notice from Borrower Agent, the Agent shall deliver the pledged stock certificates evidencing GT Holdings’ equity interest in GT International five (5) days prior to any permitted IPO; provided, further, that in the event that the

69 IPO does not occur within ten (10) days of the date of such delivery, Borrowers shall immediately return such stock certificates to the Agent.

(b) In the event that Agent and the Lenders continue to make Revolving Loans hereunder after the Termination Date without a written extension of such Termination Date or after the occurrence of an Event of Default, all such Revolving Loans: (i) shall be made in the sole and absolute discretion of Agent and all of the Lenders; and (ii) shall, together with all other Obligations, be payable thereafter ON DEMAND.

(a) Appointment. Each Lender hereby designates Citizens Bank New Hampshire to act as Agent for such Lender under this Agreement and the Other Documents. Each Lender hereby irrevocably authorizes Agent to take such action on its behalf under the provisions of this Agreement and the Other Documents and to exercise such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of Agent by the terms hereof and thereof and such other powers as are reasonably incidental thereto and Agent shall hold all Collateral, payments of principal and interest, fees (except the fees set forth in the herein that are not payable to all Lenders), charges and collections (without giving effect to any collection days) received pursuant to this Agreement, for the ratable benefit of Lenders. Agent may perform any of its duties hereunder by or through its agents or employees. As to any matters not expressly provided for by this Agreement (including without limitation, collection of the Notes) 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 instructions of the Required Lenders, and such instructions shall be binding; provided, however, that Agent shall not be required to take any action which exposes Agent to liability or which is contrary to this Agreement or the Other Documents or applicable law unless Agent is furnished with an indemnification reasonably satisfactory to Agent with respect thereto.

(b) Nature of Duties. Agent shall have no duties or responsibilities except those expressly set forth in this Agreement and the Other Documents. Neither Agent nor any of its officers, directors, employees or agents shall be (i) liable for any action taken or omitted by them as such hereunder or in connection herewith, unless caused by their gross (not mere) negligence, willful misconduct, bad faith or material breach of this Agreement, or (ii) responsible in any manner for any recitals, statements, representations or warranties made by Borrowers or any officer thereof contained in this Agreement, or in any of the Other Documents or in any certificate, report, statement or other document referred to or provided for in, or received by Agent under or in connection with, this Agreement or any of the Other Documents or for the value, validity, effectiveness, genuineness, due execution, enforceability or sufficiency of this Agreement, or any of the Other Documents or for any failure of Borrowers to perform its obligations hereunder. Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any of the Other Documents, or to inspect the properties, books or records of Borrowers. The duties of Agent as respects the Advances to Borrowers shall be mechanical and administrative in nature; Agent shall not have by reason of this Agreement a fiduciary relationship in respect of any Lender; and nothing in this Agreement, expressed or implied, is

72 intended to or shall be so construed as to impose upon Agent any obligations in respect of this Agreement except as expressly set forth herein.

(c) Lack of Reliance on Agent. Independently and without reliance upon Agent or any other Lender, each Lender has made and shall continue to make (i) its own independent investigation of the financial condition and affairs of Borrowers in connection with the making and the continuance of the Revolving Loans hereunder and the taking or not taking of any action in connection herewith, and (ii) its own appraisal of the creditworthiness of Borrowers. Agent shall have no duty or responsibility, either initially or on a continuing basis, to provide any Lender with any credit or other information with respect thereto, whether coming into its possession before making of the Revolving Loans or at any time or times thereafter except as shall be provided by Borrowers pursuant to the terms hereof. Agent shall not be responsible to any Lender for any recitals, statements, information, representations or warranties herein or in any agreement, document, certificate or a statement delivered in connection with or for the execution, effectiveness, genuineness, validity, enforceability, collectibility or sufficiency of this Agreement or any Other Document, or of the financial condition of Borrowers, or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions of this Agreement, the Notes, the Other Documents or the financial condition of Borrowers, or the existence of any Event of Default or any Default.

(e) Certain Rights of Agent. If Agent shall request instructions from Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any Other Document, Agent shall be entitled to refrain from such act or taking such action unless and until Agent shall have received instructions from the Required Lenders; and Agent shall not incur liability to any Lender or Borrowers or any other Person by reason of so refraining. Without limiting the foregoing, Lenders shall not have any right of action whatsoever against Agent as a result of its acting or refraining from acting hereunder in accordance with the instructions of the Required Lenders.

(f) Reliance. Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, statement, certificate, telex, teletype or telecopier message, cablegram, order or other document or telephone message believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper person or entity, and, with respect to all legal matters pertaining to this Agreement and the Other Documents and its duties hereunder, upon advice of counsel selected by it. Agent may employ agents and attorneys-in-fact and shall not be liable for the default or misconduct of any such agents or attorneys-in-fact selected by Agent in good faith with commercially reasonable care.

(g) Notice of Default. Agent shall not be deemed to have knowledge or notice of the occurrence of any Event of Default hereunder or under the Other Documents, unless Agent has received notice from a Lender or Borrowers referring to in this Agreement or the Other Documents, describing such Event of Default and stating that such notice is a “notice of default”. In the event that Agent receives such a notice, Agent shall give notice thereof to Lenders. Agent shall take such action with respect to such Event of Default as shall be reasonably directed by the Required Lenders; provided, that, unless and until Agent shall have received such directions, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Event of Default as it shall deem advisable in the best interests of Lenders.

(h) Indemnification. To the extent Agent is not reimbursed by Borrowers, each Lender will reimburse and indemnify Agent in proportion to its Commitment Percentage, from and against any and all actual liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, out-of-pocket expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in performing its duties hereunder, or in any way relating to or arising out of this Agreement or any Other

74 Document; provided that, Lenders shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent’s or its agent’s employee’s director’s or advisor’s gross (not mere) negligence, willful misconduct, bad faith or material breach of this Agreement or any Other Document.

(i) Agent in its Individual Capacity. With respect to the obligation of Agent to lend under this Agreement, the Revolving Loans made by it shall have the same rights and powers hereunder as any other Lender and as if it were not performing the duties as Agent specified herein; and the term “Lender” or any similar term shall, unless the context clearly otherwise indicates, include Agent in its individual capacity as a Lender. Agent may engage in business with Borrowers as if it were not performing the duties specified herein, and may accept fees and other consideration from Borrowers for services in connection with this Agreement or otherwise without having to account for the same to Lenders.

(j) Delivery of Documents. To the extent Agent receives “Borrowers’ Reports” required under Article 13 of this Agreement, Agent will promptly furnish such documents and information to Lenders.

(k) Borrowers’ Undertaking to Agent. Without prejudice to its obligations to Lenders under the other provisions of this Agreement, Borrowers hereby undertake with Agent to pay to Agent from time to time on demand, or otherwise when due hereunder, all amounts from time to time due and payable by it for the account of Agent or Lenders or any of them pursuant to this Agreement to the extent not already paid. Any payment made pursuant to any such demand shall pro tanto satisfy the relevant Borrower’s obligations to make payments for the account of Lenders or the relevant one or more of them pursuant to this Agreement.

(l) No Reliance on Agent’s Customer Identification Program. Each Lender acknowledges and agrees that neither such Lender, nor any of its Affiliates, participants or assignees, may rely on the Agent to carry out such Lender’s, Affiliate’s, participant’s or assignee’s customer identification program, or other obligations required or imposed under or pursuant to the USA Patriot Act or the regulations thereunder, including the regulations contained in 31 CFR 103.121 (as hereafter amended or replaced, the “CIP Regulations”), or any other Anti-Terrorism Law, including any programs involving any of the following items relating to or in connection with any of Borrowers, any Guarantor, their Affiliates or their agents, this Agreement, the Other Documents or the transactions hereunder or contemplated hereby: (1) any identity verification procedures, (2) any recordkeeping, (3) comparisons with government lists, applicable (4) customer notices or (5) other procedures required under the CIP Regulations or other laws.

(m) USA Patriot Act Certifications From Banks and Participants. Each Lender or assignee or participant of such that is not incorporated under the laws of the United States of America or a state thereof (and is not excepted from the certification requirement contained in Section 313 of the USA Patriot Act and the applicable regulations because it is both (i) an Affiliate of a depository institution or foreign bank that maintains a physical presence in the United States or foreign county, and (ii) subject to supervision by a banking authority regulating

75 such affiliated depository institution or foreign bank) shall deliver to the Agent the certification, or, if applicable, recertification, certifying that such Lender, Purchasing Lender or Transferee is not a “shell” and certifying to other matters as required by Section 313 of the USA Patriot Act and the applicable regulations: (1) within 10 days after the Closing Date, and (2) as such other times as are required under the USA Patriot Act.

(n) Required Lenders and Unanimous Consent. The Required Lenders, Agent with the consent in writing of the Required Lenders, and Borrowers may, subject to the provisions of this Agreement, from time to time enter into written supplemental agreements, amendments to or waivers of the provisions of this Agreement or the Other Documents executed by any Borrower, for the purpose of adding or deleting any provisions or otherwise changing, varying or waiving in any manner the rights of Lenders, Agent or any Borrower thereunder or the conditions, provisions or terms thereof of waiving any Event of Default thereunder, but only to the extent specified in such written agreements; provided, however, that no such supplemental agreement, amendment, waiver or other modification to this Agreement or the Other Documents shall, without the following consent:

(i) increase the Commitment Percentage, the Commitment Amount of any Lender or the Credit Limit of each Lender without the consent of each Lender directly affected thereby;

(ii) extend the maturity of any Note or the due date for any amount payable hereunder, or decrease the rate of interest or reduce any fee payable by Borrowers to Lenders pursuant to this Agreement (other than as a result of any waiver or cure of any Event of Default) without the unanimous consent of all Lenders.

(iii) alter the Commitment Percentage of the Required Lenders or alter, amend or modify this Subsection 23(m), without the unanimous consent of all Lenders;

(iv) release any Collateral (other than in accordance with the provisions of this Agreement) without the unanimous consent of all Lenders;

(v) change the rights and duties of Agent without the consent of the Agent and the Required Lenders;

(vi) increase the WC Sub-Limit without the unanimous consent of all Lenders; or

(vii) change the financial covenants contained in Article 15 hereof without the consent of the Required Lenders.

Any such supplemental agreement shall apply equally to each Lender and shall be binding upon Borrowers, Lenders and Agent and all future holders of the Obligations. In the case of any waiver, Borrowers, Agent and Lenders shall be restored to their former positions and rights, and any Event of Default waived shall be deemed to be cured and not continuing, but no waiver of a specific Event of Default shall extend to any subsequent

76 Event of Default (whether or not the subsequent Event of Default is the same as the Event of Default which was waived), or impair any right consequent thereon.

Notwithstanding the foregoing, if the Agent and the Borrowers shall have jointly identified an obvious error or any error or omission of a technical or immaterial nature, in each case, in any provision of this Agreement or the Other Documents, then the Agent and the Borrowers shall be permitted to amend such provision and such amendment shall become effective without any further action or consent of any other party to this Agreement or the Other Documents if the same is not objected to in writing by the Required Lenders within five (5) Business Days following receipt of notice thereof.

(o) Replacement of Holdout Lender.

(i) If any action to be taken by the Lenders hereunder requires the unanimous consent, authorization, or agreement, of all Lenders, and a Lender (“Holdout Lender”) fails to give its consent, authorization or agreement, then Agent, upon at least 5 Business Days prior irrevocable notice to the Holdout Lender, may, or upon Borrowers’ request, and otherwise in compliance with the terms of this Section 23(o), permanently replace the Holdout Lender with one or more substitute lenders (each, a “Replacement Lender”), and the Holdout Lender shall have no right to refuse to be replaced hereunder. Any notice hereunder to replace the Holdout Lender shall specify an effective date for such replacement, which date shall not be later than 15 Business Days after the date such notice is given.

(ii) Prior to the effective date of such replacement, the Holdout Lender and each Replacement Lender shall execute and deliver an Assignment and Acceptance Agreement, subject only to the Holdout Lender being repaid its share of the outstanding obligations (including an assumption of its pro rata share of the risk participation liability) without any premium or penalty of any kind whatsoever. If the Holdout Lender shall refuse or fail to execute and deliver any such Assignment and Acceptance Agreement prior to the effective date of such replacement, the Holdout Lender shall be deemed to have executed and delivered such Assignment and Acceptance Agreement. Until such time as the Replacement Lender(s) shall have acquired all of the Obligations, the Commitments, and the other rights and obligations of the Holdout Lender hereunder and under the other Loan Documents, the Holdout Lender shall remain obligated to make the Holdout Lender’s pro rata share of Loans.

(iii) In the event that no new Lender is located to purchase the Holdout Lender’s Commitment, then Borrower Agent shall have the option after receipt of written notice from Agent to Borrower Agent that no new Lender has been obtained, to terminate the Commitment of the Holdout Lender. Borrowers agree to pay all reasonabe costs or out-of-pocket expenses incurred by any Lender in connection with this Section 23(o) including without limitation, all principal and accrued and unpaid interest or fees, including any accrued and unbilled LIBOR Rate Loan Prepayment Fees, if any.

In connection with each assignment, the assignee shall represent and warrant to the Agent, the assignor, each other Lender, and the Borrowers as to whether such assignee satisfies the definition of Eligible Assignee.

(b) Register. The Agent shall maintain on behalf of the Borrowers a copy of each assignment delivered to it and a register or similar list (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment Percentages

78 of and principal amount of the Loans owing to the Lenders from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrowers, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrowers and the Lenders at any reasonable time and from time to time upon reasonable prior notice. Upon each such recordation, the assigning Lender agrees to pay to the Agent a registration fee in the sum of $5,000 (the “Registration Fee”) (provided that with respect to any assignment by a Lender to a Subsidiary as provided herein, the assigning Lender shall pay to Agent its reasonable expenses incurred in connection with such assignment in lieu of such registration fee).

(c) New Notes. Upon its receipt of an Assignment and Acceptance Agreement executed by the parties to such assignment, together with each Note subject to such assignment, the Agent shall record the information contained therein in the Register. Within five (5) Business Days after receipt of notice of such assignment from Agent, the Borrowers, at Agent’s expense, shall execute and deliver to the Agent, in exchange for each surrendered Note, a new Note to the order of such assignee in an amount equal to the amount assigned to such assignee pursuant to such Assignment and Acceptance Agreement and, if the assigning Lender has retained some portion of its obligations hereunder, a new Note to the order of the assigning Lender in an amount equal to the amount retained by it hereunder. Such new Notes shall provide that they are replacements for the surrendered Notes, shall be in an aggregate principal amount equal to the aggregate principal amount of the surrendered Notes, shall be dated the effective date of such Assignment and Acceptance Agreement and shall otherwise be in substantially the form of the assigned Notes. The surrendered Notes shall be canceled and returned to the Borrower Agent.

(d) Participations. Each Lender may sell participations to one or more Lenders or other entities in all or a portion of such Lender’s rights and obligations under this Agreement and the Other Documents; provided that (a) any such sale or participation shall not affect the rights and duties of the selling Lender hereunder, (b) such participation shall not entitle such participant to any rights or privileges under this Agreement or any Other Documents, (c) such participation shall not entitle the participant to the right to approve waivers, amendments or modifications, (d) such participant shall have no direct rights against the Borrowers, (e) such sale is effected in accordance with all applicable laws, and (f) such participant shall not be a Person controlling, controlled by or under common control with, or which is not otherwise free from influence or control by any of the Borrowers (other than Sponsor Affiliated Lenders).

(e) Pledge by Lender. Any Lender may at any time pledge all or any portion of its interest and rights under this Agreement (including all or any portion of its Note) to any of the twelve Federal Reserve Banks organized under §4 of the Federal Reserve Act, 12 U.S.C. §341 or to such other Person as the Agent may approve to secure obligations of

79 such lenders. No such pledge or the enforcement thereof shall release the pledgor Lender from its obligations hereunder or under any of the other Loan Documents.

(f) No Assignment by Borrowers. No Borrower shall assign or transfer any of its rights or obligations under this Agreement without the prior written consent of each of the Lenders and any purported assignment without such consent shall be null and void. No consent to an assignment by Agent shall release any Borrower from its Obligations. Agent may assign this Agreement and its rights and duties hereunder with prior consent from Borrowers (not to be unreasonably withheld, conditioned or delayed), provided however, that Borrowers shall have no such consent or approval rights at any time while any Event of Default exists and is continuing.

(g) Disclosure. Borrowers agree to promptly cooperate with any Lender in connection with any proposed assignment or participation of all or any portion of its Commitment in accordance with the terms herein. Each of the Lenders and the Agent acknowledges and agrees for itself that information provided and to be provided by the Borrowers contains confidential non-public information related to the Borrowers and agrees to keep any information delivered or made available by the Borrowers to it confidential from anyone other than its employees, officers, attorneys and other advisors who are engaged in evaluating, administering or syndicating the Loan or rendering advice in connection therewith, and each of Agent and the Lenders agrees not to trade in the Borrowers’ securities (all of whom shall be bound by this Section 24(g)) in violation of Section 10(b) of the Securities Exchange Act of 1934, as amended, or Rule 10b-5 or any other federal securities laws or regulations thereunder, provided that nothing herein shall prevent any of the foregoing Persons from disclosing such information (i) to any potential assignees or participants who have agreed to maintain the confidentiality of such information in the manner and to the extent provided in this Section 24(g), (ii) upon the order of any court or administrative agency or upon the request of any administrative agency or authority having jurisdiction over any of the foregoing Persons or such potential assignees or participants, (iii) to the extent that such information has been publicly disclosed other than as a result of a disclosure by the foregoing Persons, (iv) otherwise as required by law or (v) to the extent necessary to enforce the Loan Documents, provided that, with respect to any Lender disclosing information pursuant to the preceding clause (ii) that would result in such information becoming publicly available, such Lender agrees to use its commercially reasonable efforts to furnish the Borrower Agent with prior notice of such disclosure and an opportunity to contest such disclosure as long as furnishing such notice and opportunity is practicable and would not result in the Lenders’ violation of the requirements of law.

Waiver on any one occasion shall not be construed as a bar to or waiver of any right or remedy on any future occasion.

Each such Letter of Credit Request shall contain (i) a statement as to the purpose for which such Letter of Credit shall be used (which purpose shall be in accordance with the terms of this Agreement), and (ii) a certification by a Responsible Officer of Borrower Agent that the Borrowers are and will be in compliance with all covenants under the Loan Documents after giving effect to the issuance of such Letter of Credit, and otherwise that no Default or Event of Default has occurred and is continuing. The Borrowers shall further deliver to the Issuing Lender such additional applications and documents as the Issuing Lender may require, in conformity with the then standard practices of its letter of credit department, in connection with the issuance of such Letter of Credit; provided that in the event of any conflict, the terms of this Agreement shall control.

(c) The Issuing Lender shall, if it approves of the content of the Letter of Credit Request (which approval shall not be unreasonably withheld, conditioned or delayed), and subject to the conditions set forth in this Agreement, issue the Letter of Credit on or before three (3) Business Days following receipt of the documents last due pursuant to Section 5III(b), above. Each Letter of Credit shall be in form and substance reasonably satisfactory to the Issuing Lender in its reasonable discretion, and no Letter of Credit shall have an expiration date later than six (6) months following the Termination Date. Upon issuance of a Letter of Credit, the Issuing Lender shall provide notice of the issuance of such Letter of Credit to the Lenders and shall provide a copy of such Letter of Credit to any Lender that requests a copy.

(d) Upon the issuance of a Letter of Credit, each Lender shall be deemed to have purchased a participation therein from Issuing Lender in an amount equal to its respective Commitment Percentage of the amount of such Letter of Credit. No Lender’s obligation to participate in a Letter of Credit shall be affected by any other Lender’s failure to perform as required herein with respect to such Letter of Credit or any other Letter of Credit.

(e) There shall be no fee based upon the face amount of any Letter of Credit in connection with the issuance thereof. Borrowers shall however, pay to Agent for the accounts of the Lenders in accordance with their respective percentage shares of participation in such Letter of Credit, a Letter of Credit Commission fee (the “LC Commission”) calculated at the rate per annum equal to a percentage of the face amount of such Letter of Credit. The LC Commission rate shall be set at the time of issuance of the applicable Letter of Credit and calculated according to the fee schedule set forth in the definition of “Applicable Margin” in Section 5(I)(A)(i), and which such LC Commission

Fees shall be payable in quarterly installments in arrears with respect to each Letter of Credit on the fifth day following the end of each calendar quarter after the date of issuance and continuing for each quarter or portion thereof thereafter, as applicable, or on any earlier date on which the Commitments shall terminate and on the expiration or return of any Letter of Credit. In the event that Borrowers deliver cash collateral to the Agent in connection with and for the full amount of a requested Letter of Credit at the time of such request, then the LC Commission rate for such Letter of Credit shall be set at the lowest LC Commission rate provided herein. In addition, the Borrowers shall pay to Issuing Lender for its own account within five (5) days of demand of Issuing Lender the standard and reasonable issuance, documentation and service charges for Letters of Credit issued from time to time by Issuing Lender, provided however that so long as Issuing Lender is Citizens, if Borrowers have not made such payment to Citizens within said five (5) day period, then Agent shall make such payment and treat the same as a Revolving Loan for working capital purposes.

(f) In the event that any amount is drawn under a Letter of Credit by the beneficiary thereof, the Borrowers shall cause the Issuing Lender to be reimbursed as follows: (i) Agent shall immediately and without notice to Borrowers, treat such amount drawn as a Revolving Loan under this Agreement for working capital purposes. The Agent shall promptly notify each Lender by telex, telecopy, telegram, telephone (confirmed in writing) or other similar means of transmission, and each Lender shall promptly and unconditionally pay to the Agent, for the Issuing Lender’s own account, an amount equal to such Lender’s Commitment Percentage of such Letter of Credit (to the extent of the amount drawn). If and to the extent any Lender shall not make such amount available on the Business Day on which such draw is funded, such Lender agrees to pay such amount to the Agent forthwith on demand, together with interest thereon, for each day from the date on which such draw was funded until the date on which such amount is paid to the Agent, at the Federal Funds Effective Rate until three (3) days after the date on which the Agent gives notice of such draw and at the Federal Funds Effective Rate plus 1% for each day thereafter. Further, such Lender shall be deemed to have assigned any and all payments made of principal and interest on its Loans, amounts due with respect to its participations in Letters of Credit and any other amounts due to it hereunder to the Agent to fund the amount of any drawn Letter of Credit which such Lender was required to fund pursuant to this Section 5(III)(f) until such amount has been funded (as a result of such assignment or otherwise). In the event of any such failure or refusal, the Lenders not so failing or refusing shall be entitled to a priority position as against the Lender or Lenders so failing or refusing to make such funds available to the Borrowers, for such amounts as provided in Section 5(V). The failure of any Lender to make funds available to the Agent in such amount shall not relieve any other Lender of its obligation hereunder to make funds available to the Agent pursuant to this Section 5(III)(f).

(g) If after the issuance of a Letter of Credit pursuant to Section 5(III) by the Issuing Lender, but prior to the funding of any portion thereof by a Lender, one of the events described in Section 16(a)(i) or (viii) shall have occurred, each Lender will, on the date such Revolving Credit Loan pursuant to Section 5(III)(f) was to have been made, purchase an undivided participation interest in the Letter of Credit in an amount equal to its Revolving Credit Commitment Percentage of the amount of such Letter of Credit. Each Lender will immediately transfer to the Issuing Lender in immediately available funds the amount of its participation and upon receipt thereof the Issuing Lender will deliver to such Lender a Letter of Credit participation certificate dated the date of receipt of such funds and in such amount.

(h) Whenever at any time after the Issuing Lender has received from any Lender any such Lender’s payment of funds under a Letter of Credit and thereafter the Issuing Lender receives any payment on account thereof, then the Issuing Lender will distribute to such Lender its participation interest in such amount (appropriately adjusted in the case of interest payments to reflect the period of time during which such Lender’s participation interest was outstanding and funded); provided, however, that in the event that such payment received by the Issuing Lender is required to be returned, such Lender will return to the Issuing Lender any portion thereof previously distributed by the Issuing Lender to it.

(i) The issuance of any supplement, modification or amendment affecting the amount of any Letter of Credit or any renewal or extension of the term for more than thirty (30) days to any Letter of Credit shall be treated in all respects the same as the issuance of a new Letter of Credit.

(j) Borrowers assume all risks of the acts, omissions, or misuse of any Letter of Credit by the beneficiary thereof. To the extent permitted by applicable law, none of the Agent, Issuing Lender or any Lender will be responsible for (i) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the issuance of any Letter of Credit, even if such document should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (ii) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex or otherwise; (iii) any loss or delay in the transmission or otherwise of any document or draft required by or from a beneficiary in order to make a disbursement under a Letter of Credit or the proceeds thereof; (iv) for the misapplication by the beneficiary of any Letter of Credit of the proceeds of any drawing under such Letter of Credit; and (v) for any consequences arising from causes beyond the control of Agent or any Lender. Provided there exists no negligence or willful misconduct on the part of the Agent, Issuing Lender or any Lender, then none of Agent, Issuing Lender or any Lender will be responsible for (i) failure of any beneficiary of any Letter of Credit to comply fully with the conditions required in order to demand payment under a Letter of Credit; (ii) errors in interpretation of technical terms; (iii) the form, validity, sufficiency, accuracy, genuineness or legal effect of any Letter of Credit; and (iv) the form, validity, sufficiency, accuracy, genuineness or legal effect of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof in whole or in part, which may prove to be invalid or ineffective for any reason. Notwithstanding the foregoing, in no event shall the Lender be responsible for any acts of fraud or forgery by Borrowers any of its Subsidiaries or any third party in connection with the issuance, transfer, presentment or payment under or in connection with any Letter of Credit. None of the foregoing will affect, impair or prevent the vesting of any of the rights or powers granted to Agent, Issuing Lender or the Lenders hereunder. In furtherance and extension and not in limitation or derogation of any of the foregoing, any act taken or omitted to be taken by Agent, Issuing Lender or the other Lenders in good faith will be binding on Borrowers and will not put Agent, Issuing Lender or the other Lenders under any resulting liability to Borrowers.

(k) An Issuing Lender may resign as Issuing Lender hereunder at any time upon at least sixty (60) days prior notice to the Lenders, the Agent and the Borrower Agent. The Issuing Lender may be replaced at any time by written agreement among the Borrowers, each Agent, the replaced Issuing Lender and the successor Issuing Lender. The

Agent shall notify the Lenders of any such replacement of the Issuing Lender or any such additional Issuing Lender. At the time any such resignation or replacement shall become effective, the Borrowers shall pay all unpaid fees accrued for the account of the replaced Issuing Lender. From and after the effective date of any such resignation or replacement or addition, as applicable, (a) the successor or additional Issuing Lender shall have all the rights and obligations of the Issuing Lender under this Agreement with respect to Letters of Credit to be issued by it thereafter and (b) references herein to the term “Issuing Lender” shall be deemed to refer to such successor or such addition or to any previous Issuing Lender, or to such successor or such addition and all previous Issuing Lenders, as the context shall require. After the resignation or replacement of an Issuing Lender hereunder, the replaced Issuing Lender shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Lender under this Agreement with respect to Letters of Credit issued by it prior to such resignation or replacement, but shall not be required to issue additional Letters of Credit. If at any time there is more than one Issuing Lender hereunder, the Borrower Agent may, in its discretion, select which Issuing Lender is to issue any particular Letter of Credit.

IV. Repayments, Prepayments and Interest.

(i) the then current rate for United States Treasury securities (bills on a discounted basis shall be converted to a bond equivalent) with a maturity date closest to the end of the Interest Period as to which prepayment is made, subtracted from

(ii) the LIBOR Lending Rate plus the Applicable Margin applicable to the LIBOR Rate Loan being prepaid.

If the result of this calculation is zero or a negative number, then there shall be no LIBOR Rate Loan Prepayment Fee. If the result of this calculation is a positive number, then the resulting percentage shall be multiplied by:

(iii) the amount of the LIBOR Rate Loan being prepaid.

The resulting amount shall be divided by:

(iv) 360

and multiplied by:

(v) the number of days remaining in the Interest Period as to which the prepayment is being made.

Said amount shall be reduced to present value calculated by using the referenced United States Treasury securities rate and the number of days remaining in the Interest Period for the LIBOR Rate Loan being prepaid.

The resulting amount of these calculations shall be the then applicable LIBOR Rate Loan Prepayment Fee.

V. Manner of Borrowing and Payment.

VI. Miscellaneous LIBOR Rate Loan Terms.

(i) US dollar deposits in the relevant amount and for the relevant Interest Period are not available to the Agent (or any Lender) in the London interbank market;

(ii) by reason of circumstances affecting the Agent (or any Lender) in the London interbank market, adequate means do not exist for ascertaining the LIBOR Rate applicable hereunder to LIBOR Rate Loans of any duration, or

(iii) the LIBOR Rate no longer adequately reflects the Agent’s (or any Lender’s) cost of funding loans,

then, upon notice from the Agent (or any Lender) to the Borrower Agent, the obligations of the Agent (or any Lender) under this section to make or continue any LIBOR Rate Loans, or to convert any Revolving Loans, as applicable, into, LIBOR Rate Loans of such duration shall forthwith be suspended until the Agent (or any Lender) shall notify the Borrower Agent that the circumstances causing such suspension no longer exist. Agent shall use reasonable efforts to provide Borrower Agent with written notice of any such suspension of LIBOR Rate Loans.

(i) any conversion or repayment or prepayment of the principal amount of any LIBOR Rate Loans on a date other than the scheduled last day of the Interest Period applicable thereto;

(ii) any Revolving Loans not being made as LIBOR Rate Loans in accordance with the borrowing request thereof;

(iii) any LIBOR Rate Loans not being continued as, or converted into, LIBOR Rate Loans in accordance with the continuation/conversion notice thereof, or

(iv) any costs associated with marking to market any Hedging Obligations that (in the reasonable determination of the Agent (or any Lender or any Affiliates of any Lender party to a Hedging Contract)) are required to be terminated as a result of any conversion, repayment or prepayment of the principal amount of any LIBOR Rate Loan on a date other than the scheduled last day of the Interest Period applicable thereto.

The Agent (or any Lender) shall promptly notify the Borrower Agent in writing of the occurrence of any such event, such notice to state, in reasonable detail, the reasons therefor and the additional amount required fully to compensate the Agent (or any Lender) for such increased cost or reduced amount. Such additional amounts shall be payable by the Borrowers to the Agent (or any Lender) within ten (10) Business Days of its receipt of such notice, and such notice shall, in the absence of manifest error, be conclusive and binding on the Borrowers. The Borrowers understand, agree and acknowledge the following: (a) the Agent (or any Lender) does not have any obligation to purchase, sell and/or match funds in connection with the use of LIBOR Rate as a basis for calculating the rate of interest on a LIBOR Rate Loan, (b) the LIBOR Rate may be used merely as a reference in determining such rate, and (c) the Borrowers having accepted the LIBOR Rate as a reasonable and fair basis for calculating such rate, the LIBOR Rate Loan Prepayment Fee, and other funding losses incurred by the Agent (or

any Lender) (without any duplication of the LIBOR Rate Loan Prepayment Fee). As provided herein, Borrowers agree to pay the LIBOR Rate Loan Prepayment Fee as well as other funding losses, if any (and without duplication), whether or not the Agent (or any Lender) elects to purchase, sell and/or match funds.

(i) shall subject the Agent (or any Lender) to any tax, duty or other charge with respect to its LIBOR Rate Loans or its obligation to make LIBOR Rate Loans, or shall change the basis of taxation of payments to the Agent of the principal of or interest on its LIBOR Rate Loans or any other amounts due under this Agreement in respect of its LIBOR Rate Loans or its obligation to make LIBOR Rate Loans (except for the introduction of, or change in the rate of, tax on the overall net income of the Agent (or any Lenders) or franchise taxes, imposed by the jurisdiction (or any political subdivision or taxing authority thereof) under the laws of which the Agent is organized or in which the Agent’s principal executive office is located); or

(ii) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System of the United States) against assets of, deposits with or for the account of, or credit extended by, the Agent or shall impose on the Agent or on the London interbank market any other condition affecting its LIBOR Rate Loans or its obligation to make LIBOR Rate Loans;

and the result of any of the foregoing is to increase the cost to the Agent (or any Lender) of making or maintaining any LIBOR Rate Loan, or to reduce the amount of any sum received or receivable by the Agent (or any Lender) under this Agreement with respect thereto, by an amount deemed by the Agent to be material, then, within fifteen (15) days after written demand by the Agent (with supporting documentation, as applicable), the Borrowers shall pay to the Agent such additional amount or amounts as will compensate the Agent for such increased cost or reduction.

(i) pay directly to the relevant authority the full amount required to be so withheld or deducted;

(ii) promptly forward to the Agent an official receipt or other documentation satisfactory to the Agent evidencing such payment to such authority; and

(iii) pay to the Agent such additional amount or amounts as is necessary to ensure that the net amount actually received by the Agent will equal the full amount the Agent would have received had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against the Agent (or any Lender) with respect to any payment received by the Agent hereunder, the Agent may pay such Taxes and the Borrowers will promptly pay such additional amount (including any penalties, interest or expenses) as is necessary in order that the net amount received by the Agent after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount the Agent would have received had not such Taxes been asserted.

If any Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Agent (and all Lenders) the required receipts or other required documentary evidence, the Borrowers shall indemnify the Agent (and all Lenders) for any incremental Taxes, interest or penalties that may become payable by the Agent as a result of any such failure.

(a) In order to facilitate the borrowing procedures hereunder, Borrowers hereby recognize that it is advantageous and convenient for them to, and as such, is hereby authorized to, appoint one of them, from time to time to act as agent for the Borrowers to effect borrowings and other extensions of credit under this Agreement and to designate a Borrower to which proceeds of the borrowings shall be distributed (individually and collectively, the “Borrower Agent”). Each of GT Solar, GT Holdings and GT Equipment hereby appoint GT International as such corporation’s Borrower Agent to request, receive and distribute loans hereunder and to communicate with Agent with respect thereto, and GT International does hereby accept such appointment.

(b) Upon appointment of a Borrower Agent other than GT International, the Borrowers shall provide Agent with notice thereof, along with an incumbency certificate and any other required corporate or company authority documents as may be requested by the Agent, including resolutions, as appropriate, properly evidencing the authority of the Borrower Agent. Upon delivery to Agent of all requested authority documents, each Borrower shall be deemed to have irrevocably appointed such Borrower Agent as its agent to effect borrowings, obtain other extensions of credit and to execute instruments and documents and take other actions in the name, or on behalf of, but not as a lender to, such Borrower, as provided or contemplated in this

Agreement. Each Borrower represents and covenants that all requests for Loans and Letters of Credit under this Agreement shall be made by either the Borrowers or Borrower Agent as agent for the Borrowers, and that the authority of the Borrower Agent so to request Loans and Letters of Credit on behalf of, and to bind, the Borrowers, shall continue unless and until (i) the Agent actually receives written notice of the termination and/or replacement of such authority signed by an Responsible Officer of each of the Borrowers, (ii) this Agreement has been terminated, or (iii) all Obligations of such Borrower have been paid or otherwise satisfied. Notwithstanding any provision to the contrary elsewhere in this Agreement or such other Loan Documents, the Borrower Agent shall not have any duties or responsibilities, except those expressly set forth herein and therein, or any fiduciary relationship with any Borrower and no implied covenants, functions, responsibilities duties, obligations or liabilities shall be read into this Agreement or the other Loan Documents or otherwise exist against the Borrower Agent. Furthermore, in performing his duties under this appointment, the Borrower Agent shall be acting solely as a conduit for money transfers between the Lenders and the Borrowers, and the Borrower Agent shall not make, nor shall he be construed as making, any loans or advances of money under this Agreement to any of the Borrowers.

(c) Each Borrower further agrees and acknowledges that any Loans which may be made by the Lenders pursuant to the terms of this Agreement may be made directly to the Borrower Agent notwithstanding any notice or knowledge by the Lenders that such Loan is intended for the use of another Borrower, and the Lenders shall have no responsibility with respect to whether or when the Borrower Agent distributes or delivers the proceeds of any Loans to any other Borrower, and payment or delivery by the Agent of the proceeds of such Loans to the Borrower Agent shall be deemed to be a payment or delivery to each Borrower. Without limiting the foregoing, each Borrower acknowledges that it shall be directly indebted to the Lenders for each Loan distributed to it by the Borrower Agent as if that Loan had been made directly by the Lenders to the Borrowers which received such proceeds, in addition to which the other Borrowers shall be jointly and severally obligated to the Lenders in that amount.

(d) The Agent shall have no responsibility to inquire as to the distribution of Loans and Letters of Credit made by the Agent or Issuing Lender through the Borrower Agent as described herein.

(e) [Reserved.]

(f) The Facility established in this Agreement constitutes one combined aggregate Line of Credit for all of the Borrowers.

If, after the Closing Date, any change in, or the introduction, adoption, effectiveness, interpretation, reinterpretation or phase-in of, any law or regulation, directive, guideline, decision or request (whether or not having the force of law) of any court, central bank,

regulator or other governmental authority affects or would affect the amount of capital required or expected to be maintained by the Agent or any Lender, or person controlling the Agent or any Lender, and the Agent or such Lender determines (in its sole and absolute discretion) that the rate of return on its or such controlling person’s capital as a consequence of its commitments or the loans made by the Agent or any Lender is reduced to a level below that which the Agent or any Lender or such controlling person could have achieved but for the occurrence of any such circumstance, then, in any such case upon notice from time to time by the Agent to the Borrower Agent, the Borrowers shall within three (3) Business Days of written demand therefor (along with supporting documentation, if any, as applicable), pay directly to the Agent additional amounts sufficient to compensate the Agent (or any Lender) or such controlling person for such reduction in rate of return. A statement of the Agent or any such Lender as to any such additional amount or amounts (including calculations thereof in reasonable detail) shall, in the absence of manifest error, be conclusive and binding on the Borrowers. In determining such amount, the Agent or any such Lender may use any method of averaging and attribution that it (in its sole and absolute discretion) shall deem applicable.

In addition, upon the occurrence and during the continuance of an Event of Default, if Agent proceeds to enforce payment of the Obligations at the option and direction of the Required Lenders, (i) Borrowers shall be obligated to deliver to Agent cash collateral in an amount equal to one hundred three (103%) percent of the aggregate amounts then undrawn on all Outstanding Letters of Credit or acceptances issued or guaranteed by Agent or its Affiliates for the account of the Borrowers plus all applicable fees and expenses, or in the alternative, and (ii) Agent shall, at the direction of the Lenders, either setoff Borrowers’ deposit accounts held as Collateral herunder or (and regardless of whether the conditions precedent in this Agreement for a Revolving Loan have been satisfied), the Lenders will cause a Revolving Loan to be made in the aggregate amounts then undrawn on all Outstanding Letters of Credit or acceptances issued or guaranteed by Agent or its Affiliates for the account of the Borrowers plus all applicable fees and expenses, and Agent may proceed to enforce payment of the same and to exercise all rights and remedies afforded to Agent by the Uniform Commercial Code or under the terms of this Agreement or otherwise. Upon the occurrence of, and during the continuance of, an Event of Default, the Borrowers, as additional compensation to the Agent and Lenders for their increased credit risk, shall pay interest on all outstanding Obligations (other than Hedging Contracts) (including, without limitation, principal, whether or not past due, past due interest and any other amounts past due under this Agreement) at a per annum rate of two (2%) percent greater than, the rate of interest then specified in Article 5 of this Agreement (the “Default Rate”). The Lenders acknowledge that an Event of Default hereunder is not considered a termination event or event of default under the Hedging Contracts.

(a) Each Borrower is accepting joint and several liability under this Agreement in consideration of the financial accommodations to be provided by Agent and each Lender under this Agreement, for the mutual benefit, directly and indirectly, of each Borrower and in consideration of the undertakings of each other Borrower to accept joint and several liability for the Obligations of each Borrower to the Agent and each Lender and in consideration and furtherance of the corporate purpose of the Borrowers’ affiliated corporate relationship and structure.

(b) Each Borrower, jointly and severally, hereby irrevocably and unconditionally accepts, not merely as a surety but also as a co-debtor, joint and several liability with each other Borrower, with respect to the payment and performance of all of the Obligations of each Borrower to the Lenders under this Agreement (including, without limitation, any Obligations arising under this section), it being the intention of the parties hereto that all the Obligations of each Borrower to the Lenders under this Agreement shall be the joint and several Obligations of each of the Borrowers without preferences or distinction among them.

(c) If and to the extent that any of the Borrowers shall fail to make any payment with respect to any of the Obligations of each Borrower to the Lenders under this Agreement, as and when due or to perform any of such Obligations in accordance with the terms thereof, then in each such event the other Borrower, under this Agreement will make such payment with respect to, or perform, such Obligation.

(d) The Obligations of each Borrower under the provisions of this section constitute full recourse Obligations of each Borrower enforceable (except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law), against each such Borrower to the full extent of its properties and assets, irrespective of the validity, regularity or enforceability of this Agreement or any other circumstance whatsoever.

(e) To the extent permitted by applicable law, each Borrower hereby waives notice of acceptance of its joint and several liability, notice of any loans made under this Agreement, notice of any action at any time taken or omitted by Agent under or in respect of any of the Obligations of each Borrower to the Lenders under this Agreement, and, generally, to the extent permitted by applicable law, all demands, notices and other formalities of every kind in

connection with this Agreement. To the extent permitted by applicable law, each Borrower hereby assents to, and waives notice of, any extension or postponement of the time for the payment of any of the Obligations of each Borrower to the Lenders under this Agreement, the acceptance of any payment of any of such Obligations, the acceptance of any partial payment thereon, any waiver, consent or other action or acquiescence by the Lenders at any time or times in respect of any default by any Borrower in the performance or satisfaction of any term, covenant, condition or provision of this Agreement, any and all other indulgences whatsoever by the Lenders in respect of any of the Obligations of each Borrower to the Lenders under this Agreement, and the taking, addition, substitution or release, in whole or in part, at any time or times, of any security for any of such Obligations of each Borrower to the Lenders or the addition, substitution or release, in whole or in part, of any Borrower. Without limiting the generality of the foregoing, to the extent permitted by applicable law, each Borrower assents to any other action or delay in acting or failure to act on Agent’s part with respect to the failure by any Borrower to comply with any of its respective Obligations, including, without limitation, any failure strictly or diligently to assert any right or to pursue any remedy or to comply fully with applicable laws or regulations thereunder, which might, but for the provisions of this section, afford grounds for terminating, discharging or relieving any Borrower, in whole or in part, from any of its Obligations under this section, it being the intention of each Borrower that, so long as any of the Obligations under this Agreement remain unsatisfied, the Obligations of such Borrower under this section shall not be discharged except by performance and then only to the extent of such performance. To the extent permitted by applicable law, the Obligations of each Borrower under this section shall not be diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation, reconstruction or similar proceeding with respect to any other Borrower or any Lender. The joint and several liability of each Borrower under this Agreement shall continue in full force and effect notwithstanding any absorption, merger, amalgamation or any other change whatsoever in the name, membership, constitution or place of formation of any Borrower or Lender.

(f) The provisions of this section are made for the benefit of the Agent and the Lenders’ permitted successors and assigns, and may be enforced by Agent for the benefit of the Lenders in good faith from time to time against any or all of the Borrowers as often as occasion therefor may arise and without requirement on Agent’s part first to marshal any of its claims or to exercise any of its rights against any Borrower or to exhaust any remedies available to Agent against any other Borrower or to resort to any other source or means of obtaining payment of any of the Obligations under this Agreement or to elect any other remedy. The provisions of this section shall remain in effect until all of the Obligations of each Borrower to the Lenders under this Agreement shall have been paid in full or otherwise fully satisfied. If at any time, any payment, or any part thereof, made in respect of any of such Obligations of each Borrower to the Lenders, is rescinded or must otherwise be restored or returned by Bank upon the insolvency, bankruptcy or reorganization of any Borrower, or otherwise, the provisions of this section will forthwith be reinstated in effect, as though such payment had not been made.

(g) Each Borrower agrees that it shall not exercise, and hereby expressly waives until full and final payment of all Obligations to the Lenders: (i) any right to subrogation or indemnification, and any other right to payment from or reimbursement by any other Borrower, in connection with or as a consequence of any payment made by any Borrower to the

Lenders, (ii) any right to enforce any right or remedy which the Lenders may have or may hereafter have against any other Borrower, and (iii) any benefit of, and any right to participate in (A) any collateral now or hereafter held by the Lenders, or (B) any payment to the Lenders by, or collection by Agent from any other Borrower. The provisions of this paragraph are made for the express benefit of each Borrower as well as the Lenders, and may be enforced independently by each Borrower or any successor in interest to each Borrower.

(d) Resignation and Removal Agent may resign on sixty (60) days’ written notice to each of Lenders and Borrower Agent and upon such resignation, the Required Lenders will promptly designate a successor Agent reasonably satisfactory to Borrowers. The Required Lenders may remove the Agent from its capacity as Agent for failure to perform its material obligations under this Agreement provided that the Required Lenders shall have given prior written notice to the Agent of its failure to perform any of its material obligations under this Agreement and such failure shall not have been cured within thirty (30) calendar days after receipt of notice of such failure (or such failure cannot reasonably be cured within such thirty (30) day period, then within such longer period of time as may be necessary to complete such cure so long as Agent commences such cure within such thirty (30) day period and thereafter diligently pursues such cure to completion). Upon any such resignation or removal, the Required Lenders shall have the right to appoint as a successor Agent which shall be any Lender or any financial institution whose senior debt obligations are rated not less than “A2” or its equivalent by ▇▇▇▇▇’▇ or not less than “A2” or its equivalent by S&P and which has a net worth of not less than $500,000,000. Unless an Event of Default shall have occurred and be continuing, such successor Agent shall be reasonably acceptable to the Borrower Agent.
