Commitment to Lend; Limitation on Total Commitment. Subject to the provisions of 2.5 and the other terms and conditions set forth in this Agreement, each of the Banks severally agrees to lend to the Borrower and the Borrower may borrow, repay, and reborrow from time to time between the Effective Date and the Maturity Date (or, if the Term Extension Option is exercised, the Term Extension Maturity Date) upon notice by the Borrower to the Agent given and approved by the Agent in accordance with 2.5, such sums as are requested by the Borrower up to a maximum aggregate principal amount outstanding (after giving effect to all amounts requested) at any one time equal to such Bank's Commitment, provided that the sum of the outstanding amount of the Loans (after giving effect to all amounts requested) shall not at any time exceed the Maximum Loan Amount. The Loans shall be made pro rata in accordance with each Bank's Commitment Percentage and the Banks shall at all times immediately adjust inter se any inconsistency between each Bank's outstanding principal amount and each Bank's Commitment. Each request for a Loan hereunder shall constitute a representation and warranty by the Borrower that the conditions set forth in 10 or 11 (whichever is applicable) have been satisfied on the date of such request and will be satisfied on the proposed Drawdown Date of the requested Loan, provided that the making of such representation and warranty by Borrower shall not limit the right of any Bank not to lend upon a determination by the Requisite Banks that such conditions have not been satisfied. 2.2. Reduction of Commitment. The Borrower shall have the right effective upon the extension of the Maturity Date pursuant to 3.1, upon at least ten (10) Business Days' prior written notice to the Agent, to reduce by $1,000,000 or an integral multiple of $100,000 in excess thereof the unborrowed portion of the then Total Commitment, provided that the Total Commitment shall not be reduced to less than $50,000,000, whereupon the Commitments of the Banks shall be reduced pro rata in accordance with their respective Commitment Percentages by the amount specified in such notice. Upon the effective date of any such reduction, the Borrower shall pay to the Agent for the respective accounts of the Banks the full amount of any commitment fee then accrued on the amount of the reduction. No reduction of the Commitments may be reinstated. 2.3. The Notes. The Loans shall be evidenced by separate promissory notes of the Borrower in substantially the form of Exhibit A hereto (each a "Note"), and completed with appropriate insertions. A Note shall be payable to the order of each Bank in a principal amount equal to such Bank's Commitment. The Borrower irrevocably authorizes each Bank to make or cause to be made, at or about the time of the Drawdown Date of any Loan or at the time of receipt of any payment of principal on such Bank's Note, an appropriate notation on such Bank's Record reflecting the making of such Loan or (as the case may be) the receipt of such payment. The outstanding amount of the Loans set forth on such Bank's Record shall (absent manifest error) be prima facie evidence of the principal amount thereof owing and unpaid to such Bank, but the failure to record, or any error in so recording, any such amount on the Record shall not limit or otherwise affect the obligations of the Borrower hereunder or under any Note to make payments of principal of or interest on any Note when due. 2.4. Interest on Loans. (a) Each Base Rate Loan shall bear interest for the period commencing with the Drawdown Date thereof and ending on the last day of the Interest Period with respect thereto at the Base Rate. (b) Each Eurodollar Rate Loan shall bear interest for the period commencing with the Drawdown Date thereof and ending on the last day of the Interest Period with respect thereto at the rate of 160 basis points per annum above the Eurodollar Rate determined for such Interest Period. (c) The Borrower unconditionally promises to pay interest on each Loan in arrears on each Interest Payment Date with respect thereto. 2.5. Requests for Loans. (a) The Borrower shall give to the Agent written notice in the form of Exhibit B hereto of each Loan requested hereunder (a "Loan Request") no less than (a) two (2) Business Days prior to the proposed Drawdown Date of any Base Rate Loan and (b) four (4) Eurodollar Business Days prior to the proposed Drawdown Date of any Eurodollar Rate Loan. Each such notice shall specify (i) the principal amount of the Loan requested, (ii) the proposed Drawdown Date of such Loan, (iii) the Interest Period for such Loan, and (iv) the Type of such Loan, and shall be accompanied by a statement in the form of Exhibit C hereto signed by a Responsible Officer setting forth in reasonable detail computations evidencing compliance with the covenants contained in 9.1 through 9.7 hereof after giving effect to such requested Loan (a "Compliance Certificate"). Promptly upon receipt of a Loan Request, the Agent shall notify each of the Banks thereof and each Bank shall immediately notify the Agent if it believes that any of the conditions contained in 11 of this Agreement has not been met or waived. If such a notice is given the Requisite Banks shall promptly determine whether all of the conditions contained in 11 of this Agreement have been met or waived. If no such notice is given by any Bank or if following such notice the Requisite Banks determine that the conditions contained in 11 have been met or waived, each of the Banks shall be obligated to fund its Commitment Percentage of the requested Loans. Each such Loan Request shall be irrevocable and binding on the Borrower and the Borrower shall be obligated to accept the Loan requested from the Banks on the proposed Drawdown Date. Each Loan Request shall be in a minimum aggregate amount of $3,000,000 or an integral multiple of $1,000,000 in excess thereof. (b) Notwithstanding anything contained in 2.5 (a) to the contrary, in the event that the making of a requested Loan would cause non-compliance with any of the covenants contained in 9.1 through 9.7 hereof, the Agent may, in its sole discretion, reduce the amount of the Loan Request to an amount which would enable the Borrower to maintain compliance with such otherwise defaulted covenant or covenants and Borrower shall accept the Loan made pursuant to such reduced Loan Request. 2.6. Conversion Options. (a) The Borrower may elect from time to time to convert any outstanding Loan to a Loan of another Type, provided that (i) with respect to any such conversion of a Eurodollar Rate Loan to a Base Rate Loan, the Borrower shall give the Agent at least three (3) Business Days, prior written notice of such election; (ii) with respect to any such conversion of a Eurodollar Rate Loan into a Base Rate Loan, such conversion shall only be made on the last day of the Interest Period with respect thereto; (iii) subject to the further proviso at the end of this section and subject to 2.6(b) and 2.6(d) hereof with respect to any such conversion of a Base Rate Loan to a Eurodollar Rate Loan, the Borrower shall give the Agent at least four (4) Eurodollar Business Days, prior written notice of such election and (iv) no Loan may be converted into a Eurodollar Rate Loan when any Default or Event of Default has occurred and is continuing. On the date on which such conversion is being made, each Bank shall take such action as is necessary to transfer its Commitment Percentage of such Loans to its Domestic Lending Office or its Eurodollar Lending Office, as the case may be. All or any part of outstanding Loans of any Type may be converted as provided herein, provided further that each Conversion Request relating to the conversion of a Base Rate Loan to a Eurodollar Rate Loan shall be for an amount equal to $3,000,000 or an integral multiple of $1,000,000 in excess thereof and shall be irrevocable by the Borrower. (b) Any Loans of any Type may be continued as such upon the expiration of an Interest Period with respect thereto by compliance by the Borrower with the notice provisions contained in 2.6 (a) ; provided that no Eurodollar Rate Loan may be continued as such when any Default or Event of Default has occurred and is continuing but shall be automatically converted to a Base Rate Loan on the last day of the first Interest Period relating thereto ending during the continuance of any Default or Event of Default of which the officers of the Agent active upon the Borrower's account have actual knowledge. (c) In the event that the Borrower does not notify the Agent of its election hereunder with respect to any Loan, such Loan shall be automatically converted to a Base Rate Loan at the end of the applicable Interest Period. (d) The Borrower may not request a Eurodollar Rate Loan pursuant to 2.5, elect to convert a Base Rate Loan to a Eurodollar Rate Loan pursuant to 2.5(a) or elect to continue a Eurodollar Rate Loan pursuant to 2.6(b) if, after giving effect thereto, there would be greater than six (6) Eurodollar Rate Loans outstanding. Any Loan Request for a Eurodollar Rate Loan that would create greater than six (6) Eurodollar Rate Loans outstanding shall be deemed to be a Loan Request for a Base Rate Loan. 2.7. Funds for Loans. (a) Subject to 2.5 and other provisions of this Agreement, not later than 11:00 a.m. (Boston time) on the proposed Drawdown Date of any Loans, each of the Banks will make available to the Agent, at the Agent's Head office, in immediately available funds, the amount of such Bank's Commitment Percentage of the amount of the requested Loans. Upon receipt from each Bank of such amount, and upon receipt of the documents required by 10 or 11 (whichever is applicable) and the satisfaction of the other conditions set forth therein, to the extent applicable, the Agent will make available to the Borrower the aggregate amount of such Loans made available to the Agent by the Banks. The failure or refusal of any Bank to make available to the Agent at the aforesaid time and place on any Drawdown Date the amount of its Commitment Percentage of the requested Loans shall not relieve any other Bank from its several obligation hereunder to make available to the Agent the amount of such other Bank's Commitment Percentage of any requested Loans but shall not obligate any other Bank or Agent to fund more than its Commitment Percentage of the requested Loans or to increase its Commitment Percentage. (b) The Agent may, unless notified to the contrary by any Bank prior to a Drawdown Date, assume that such Bank has made available to the Agent on such Drawdown Date the amount of such Bank's Commitment Percentage of the Loans to be made on such Drawdown Date, and the Agent may (but it shall not be required to), in reliance upon such assumption, make available to the Borrower a corresponding amount. If any Bank makes available to the Agent such amount on a date after such Drawdown Date, such Bank shall pay to the Agent on demand an amount equal to the product of (i) the average computed for the period referred to in clause (iii) below, of the weighted average interest rate paid by the Agent for federal funds acquired by the Agent during each day included in such period, times (ii) the amount of such Bank's Commitment Percentage of such Loans, times (iii) a fraction, the numerator of which is the number of days or portion thereof that elapsed from and including such Drawdown Date to the date on which the amount of such Bank's Commitment Percentage of such Loans shall become immediately available to the Agent, and the denominator of which is 365. A statement of the Agent submitted to such Bank with respect to any amounts owing under this paragraph shall be prima facie evidence of the amount due and owing to the Agent by such Bank. 3. REPAYMENT OF THE LOANS. 3.1. Maturity; Term Extension Option. (a) The Borrower unconditionally promises to pay on the Maturity Date, and there shall become absolutely due and payable on the Maturity Date, all of the Loans outstanding on such date, together with any and all accrued and unpaid interest and charges thereon unless prior to the Maturity Date the Borrower elects the Term Extension Option pursuant to this 3.1. (b) At any time prior to the Maturity Date, provided that no Default or Event of Default has occurred and is continuing, the Borrower shall have the option to extend the Maturity Date for one (1) year subject to satisfaction of the following conditions: (a) the Borrower shall acquire the Required Interest Rate Contracts, and (b) not more than an aggregate of $10,000,000 of other Recourse Indebtedness of Borrower has a maturity which is sooner than ninety days after the extended Maturity Date. The Term Extension Option shall be exercised by written notice to the Agent at least ten (10) Business Days prior to the Maturity Date. Such written notice must be accompanied by payment of a Term Extension option fee equal to twenty-five basis points (0.25%) of the Total Commitment to be in effect after such extension taking into account any reduction pursuant to 2.2. 3.2. Mandatory Repayments of Loan. If at any time the sum of the outstanding amount of the Loans exceeds the Maximum Loan Balance, then the Borrower shall immediately pay the amount of such excess to the Agent for the respective accounts of the Banks for application to the Loans. 3.3. Optional Repayments of Loans. The Borrower shall have the right, at its election, to repay the outstanding amount of the Loans, as a whole or in part, on any Business Day, without penalty or premium; provided that the full or partial prepayment of the outstanding amount of any Eurodollar Rate Loans made pursuant to this 3.3 may be made only on the last day of the Interest Period relating thereto, except as set forth below in this 3.3. The Borrower shall give the Agent no later than 10:00 a.m., Boston time, at least three (3) Business Days' prior written notice of any prepayment pursuant to this 3.3 of any Base Rate Loans and four (4) Eurodollar Business Days, notice of any proposed repayment pursuant to this 3.3 of any Eurodollar Rate Loans, specifying the proposed date of payment of Loans and the principal amount to be paid. Each such partial prepayment of the Loans shall be in an integral multiple of $100,000 and shall be accompanied by the payment of all charges outstanding on all Loans and of accrued interest on the principal repaid to the date of payment and shall be applied, in the absence of instruction by the Borrower, first to the principal of Base Rate Loans and then to the principal of Eurodollar Rate Loans. Notwithstanding anything contained herein to the contrary, the Borrower may make a full or partial prepayment of a Eurodollar Rate Loan on a date other than the last day of the Interest Period relating thereto, if all optional prepayments (in whole or in part) on such Loans shall be accompanied by, and the Borrower hereby promises to pay, a prepayment fee in an amount determined by the Agent in the following manner: (i) Fixed Rate Prepayment Fee. Borrower acknowledges that prepayment or acceleration of a Eurodollar Loan during an Interest Period shall result in the Banks 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. (For all purposes of this Section, any Loan not being made as a Eurodollar Rate Loan in accordance with the Loan Request therefor, as a result of Borrower's cancellation thereof, shall be treated as if such Eurodollar Rate Loan had been prepaid.) Therefore, on the date a Eurodollar Rate Loan is prepaid or the date all sums payable hereunder become due and payable, by acceleration or otherwise ("Prepayment Date"), Borrower will pay to Agent, for the account of each Bank, (in addition to all other sums then owing), an amount ("Fixed Rate Prepayment Fee") determined by the Agent to be the amount, if any, by which (i) the amount of interest which would have accrued on the prepaid Eurodollar Rate Loan for the remainder of the Interest Period at the rate applicable to such Eurodollar Rate Loan exceeds (ii) the amount of interest that would accrue on a Eurodollar Rate Loan in the same amount for the same period if the Eurodollar Rate were set on the Prepayment Date. (ii) Upon the written notice to Borrower from Agent, Borrower shall immediately pay to Agent, for the account of the Banks, the Fixed Rate Prepayment Fee. Such written notice (which shall include calculations in reasonable detail) shall, in the absence of manifest error, be conclusive and binding on the parties hereto. (iii) Borrower understands, agrees and acknowledges the following: (i) no Bank has any obligation to purchase, sell and/or match funds in connection with the use of the Eurodollar Rate as a basis for calculating the rate of interest on a Eurodollar Rate Loan; (ii) the Eurodollar Rate is used merely as a reference in determining such rate; and (iii) Borrower has accepted the Eurodollar Rate as a reasonable and fair basis for calculating such rate and a Fixed Rate Prepayment Fee. Borrower further agrees to pay the Fixed Rate Prepayment Fee, if any, whether or not a Bank elects to purchase, sell and/or match funds. 4. CERTAIN GENERAL PROVISIONS. 4.1. Revolving Credit Facility Fees and Agent's Fee. The Borrower agrees to pay to the Agent a revolving credit facility fee and agency fees in the amounts specified in the agreement regarding fees between the Agent and the Borrower and the Agent shall be responsible for any facility fees which it may agree to pay to the other Banks which become a party to this Agreement. 4.2. Commitment Fee. The Borrower shall pay to the Agent for the accounts of the Banks in accordance with their respective Commitment Percentages a commitment fee calculated at the rates set forth below per annum on the daily amount by which the Total Commitment (as it may have been reduced pursuant to 2.2) exceeds the outstanding amount of Loans (the "Unused Amount"): Unused Amount Fee Rate less than 1/3 of Total Commitment 15 basis points at least 1/3 of Total Commitment but less than 2/3 of Total Commitment 20 basis points at least 2/3 of Total Commitment 25 basis points The commitment fee shall not accrue until March 1, 1997. Thereafter, the commitment fee shall be payable on the basis of the applicable annual rate quarterly in arrears on the first day of each calendar quarter for the immediately preceding calendar quarter commencing on the first such date following the date hereof, with a final payment on the Maturity Date or, if the Term Extension Option is exercised, the Term Extension Maturity Date or any earlier date on which the Commitments shall terminate. 4.3. Funds for Payments. (a) All payments of principal, interest, closing fees, commitment fees and any other amounts due hereunder (other than as provided in 4.1, 4.5 and 4.6) or under any of the other Loan Documents, and all prepayments, shall be made to the Agent, for the respective accounts of the Banks, at the Agent's Head Office, in each case in Dollars in immediately available funds. (b) All payments by the Borrower hereunder and under any of the other Loan Documents shall be made without setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory liens, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless the Borrower is compelled by law to make such deduction or withholding. If any such obligation is imposed upon the Borrower with respect to any amount payable by it hereunder or under any of the other Loan Documents, the Borrower shall pay to the Agent, for the account of the Banks or (as the case may be) the Agent, on the date on which such amount is due and payable hereunder or under such other Loan Document, such additional amount in Dollars as shall be necessary to enable the Banks or the Agent to receive the same net amount which the Banks or the Agent would have received on such due date had no such obligation been imposed upon the Borrower. The Borrower will deliver promptly to the Agent certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by the Borrower hereunder or under such other Loan Document. 4.4. Computations. All computations of interest on the Loans and of other fees to the extent applicable shall be based on a 360-day year and paid for the actual number of days elapsed. Except as otherwise provided in the definition of the term "Interest Period" with respect to Eurodollar Rate Loans, whenever a payment hereunder or under any of the other Loan Documents becomes due on a day that is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and interest shall accrue during such extension. The outstanding amount of the Loans as reflected on the Records from time to time shall (absent manifest error) be considered correct and binding on the Borrower unless within thirty (30) Business Days after receipt by the Agent or any of the Banks from Borrower of any notice by the Borrower of such outstanding amount, the Agent or such Bank shall notify the Borrower to the contrary. 4.5. Additional Costs, Etc.

Each of the Banks agrees with each other Bank that (a) if an amount to be set off is to be applied to Indebtedness of the Borrower to such Bank, other than Indebtedness evidenced by the Notes held by such Bank, such amount shall be applied ratably to such other Indebtedness and to the Indebtedness evidenced by all such Notes held by such Bank, and (b) if such Bank shall receive from the Borrower, whether by voluntary payment, exercise of the right of setoff, counterclaim, cross action, enforcement of the claim evidenced by the Notes held by such Bank by proceedings against the Borrower at law or in equity or by proof thereof in bankruptcy, reorganization, liquidation, receivership or similar proceedings, or otherwise, and shall retain and apply to the payment of the Note or Notes held by such Bank any amount in excess of its ratable portion of the payments received by all of the Banks with respect to the Notes held by all of the Banks, such Bank will make such disposition and arrangements with the other Banks with respect to such excess, either by way of distribution, pro tanto assignment of claims, subrogation or otherwise as shall result in each Bank receiving in respect of the Notes held by it its proportionate payment as contemplated by this Agreement; provided that if all or any part of such excess payment is thereafter recovered from such Bank, such disposition and arrangements shall be rescinded and the amount restored to the extent of such recovery, but without interest.

THE AGENT. 14.1. Authorization. The Agent is authorized to take such action on behalf of each of the Banks and to exercise all such powers as are hereunder and under any of the other Loan Documents and any related documents delegated to the Agent, together with such powers as are reasonably incident thereto, provided that no duties or responsibilities not expressly assumed herein or therein shall be implied to have been assumed by the Agent.

No Liability. Neither the Agent nor any of its shareholders, directors, officers or employees nor any other Person assisting them in their duties nor any agent or employee thereof, shall be liable for any waiver, consent or approval given or any action taken, or omitted to be taken, in good faith by it or them hereunder or under any of the other Loan Documents, or in connection herewith or therewith, or be responsible for the consequences of any oversight or error of judgment whatsoever, except that the Agent or such other Person, as the case may be, may be liable for losses due to its willful misconduct or gross negligence. 14.4. No Representations. The Agent shall not be responsible for the execution or validity or enforceability of this Agreement, the Notes, any of the other Loan Documents or any instrument at any time constituting, or intended to constitute, collateral security for the Notes, or for the value of any such collateral security or for the validity, enforceability or collectability of any such amounts owing with respect to the Notes, or for any recitals or statements, warranties or representations made herein or in any of the other Loan Documents or in any certificate or instrument hereafter furnished to it by or on behalf of the Borrower, or be bound to ascertain or inquire as to the performance or observance of any of the terms, conditions, covenants or agreements herein or in any instrument at any time constituting, or intended to constitute, collateral security for the Notes. The Agent shall not be bound to ascertain whether any notice, consent, waiver or request delivered to it by the Borrower or any holder of any of the Notes shall have been duly authorized or is true, accurate and complete.

Each Bank has been independently represented by separate counsel on all matters regarding this Agreement. 14.5. Payments. (a) A payment by the Borrower to the Agent hereunder or any of the other Loan Documents for the account of any Bank shall constitute a payment to such Bank subject to the pro rata rights to repayment based upon the Commitment Percentage of each Bank. The Agent agrees promptly to distribute to each Bank such Bank's pro rata share of payments received by the Agent for the account of the Banks except as otherwise expressly provided herein or in any of the other Loan Documents. (b) If in the opinion of the Agent the distribution of any amount received by it in such capacity hereunder, under the Notes or under any of the other Loan Documents might involve it in liability, it may refrain from making distribution until its right to make distribution shall have been adjudicated by a court of competent jurisdiction. If a court of competent jurisdiction shall adjudge that any amount received and distributed by the Agent is to be repaid, each Person to whom any such distribution shall have been made shall either repay to the Agent its proportionate share of the amount so adjudged to be repaid or shall pay over the same in such manner and to such Persons as shall be determined by such court. (c) Notwithstanding anything to the contrary contained in this Agreement or any of the other Loan Documents, any Bank that fails (i) to make available to the Agent its pro rata share of any Loan or (ii) to comply with the provisions of 13 with respect to making dispositions and arrangements with the other Banks, where such Bank's share of any payment received, whether by setoff or otherwise, is in excess of its pro rata share of such payments due and payable to all of the Banks, in each case as, when and to the full extent required by the provisions of this Agreement, or to adjust promptly such Bank's outstanding principal and its pro rata Commitment Percentage as provided in 2.1 hereof, shall be deemed delinquent (a "Delinquent Bank") and shall be deemed a Delinquent Bank until such time as such delinquency is satisfied. A Delinquent Bank shall be deemed to have assigned any and all payments due to it from the Borrower, whether on account of outstanding Loans, interest, fees or otherwise, to the remaining nondelinquent Banks for application to, and reduction of, their respective pro rata shares of all outstanding Loans. The Delinquent Bank hereby authorizes the Agent to distribute such payments to the nondelinquent Banks in proportion to their respective pro rata shares of all outstanding Loans. A Delinquent Bank shall be deemed to have satisfied in full a delinquency when and if, as a result of application of the assigned payments to all outstanding Loans of the nondelinquent Banks, the Banks' respective pro rata shares of all outstanding Loans have returned to those in effect immediately prior to such delinquency and without giving effect to the nonpayment causing such delinquency. 14.6. Holders of Notes. The Agent may deem and treat the payee of any Note as the absolute owner or purchaser thereof for all purposes hereof until it shall have been furnished in writing with a different name by such payee or by a subsequent holder assignee or transferee. 14.7. Indemnity. The Banks ratably agree hereby to indemnify and hold harmless the Agent from and against any and all claims, actions and suits (whether groundless or otherwise), losses, damages, costs, expenses (including any expenses for which the Agent has not been reimbursed by the Borrower as required by 15), and liabilities of every nature and character arising out of or related to this Agreement, the Notes, or any of the other Loan Documents or the transactions contemplated or evidenced hereby or thereby, or the Agent's actions taken hereunder or thereunder, except to the extent that any of the same shall be directly caused by the Agent's willful misconduct or gross negligence. 14.8. Agent as Bank. In its individual capacity, FNBB shall have the same obligations and the same rights, powers and privileges in respect to its Commitment and the Loans made by it, and as the holder of any of the Notes as it would have were it not also the Agent. 14.9. Resignation. The Agent may resign at any time by giving sixty (60) days, prior written notice thereof to the Banks and the Borrower. Upon any such resignation, the Requisite Banks shall have the right to appoint a successor Agent. Unless a Default or Event of Default shall have occurred and be continuing, appointment of such successor Agent shall be subject to the reasonable approval of the Borrower. If no successor Agent shall have been so appointed by the Requisite Banks and shall have accepted such appointment within thirty (30) days after the giving of notice of resignation or removal of the Borrower has disapproved or failed to approve a successor agent within such period, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent, which shall be a financial institution having a rating of not less than A2/P2 or its equivalent by Standard & Poor's Corporation. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations as Agent hereunder. After any retiring Agent's resignation, the provisions of this Agreement and the other Loan Documents shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent. 14.10. Notification of Defaults and Events of Default. Each Bank hereby agrees that, upon learning of the existence of a Default or an Event of Default, it shall promptly notify the Agent thereof. The Agent hereby agrees that upon receipt of any notice under this 14.10 it shall promptly notify the other Banks of the existence of such Default or Event of Default. 14.11. Duties in the Case of Enforcement. In case one of more Events of Default have occurred and shall be continuing, and whether or not acceleration of the Obligations shall have occurred, the Agent shall, if (a) so requested by the Requisite Banks and (b) the Banks have provided to the Agent such additional indemnities and assurances against expenses and liabilities as the Agent may reasonably request, proceed to enforce the provisions of the Security Documents authorizing the sale or other disposition of all or any part of the Collateral and exercise all or any such other legal and equitable and other rights or remedies as it may have in respect of such Collateral. The Requisite Banks may direct the Agent in writing as to the method and the extent of any such sale or other disposition, the Banks hereby agreeing to indemnify and hold the Agent harmless from all liabilities incurred in respect of all actions taken or omitted in accordance with such directions, provided that the Agent need not comply with any such direction to the extent that the Agent reasonably believes the Agent's compliance with such direction to be unlawful or commercially unreasonable in any applicable jurisdiction. The Agent may take such steps as it reasonably determines for the taking of possession or title to any Collateral, including the formation of trusts or corporation with each Bank having a beneficial interest equal to its pro rata percentage of the outstanding Loans. 15. EXPENSES. The Borrower agrees to pay (a) the reasonable costs of producing and reproducing this Agreement, the other Loan Documents and the other agreements and instruments mentioned herein, (b) any taxes (including any interest and penalties in respect thereto) payable by the Agent or any of the Banks (other than taxes based upon the Agent's or any Bank's net income), including any recording, mortgage, documentary or intangibles taxes in connection with the Security Documents and other Loan Documents, or other taxes payable on or with respect to the transactions contemplated by this Agreement, including any taxes payable by the Agent or any of the Banks after the Effective Date (the Borrower hereby agreeing to indemnify the Banks with respect thereto), (c) all title insurance premiums, appraisal fees, engineer's, inspector's and surveyor's fees, recording costs and the reasonable fees, expenses and disbursements of the Agent's counsel or any local counsel to the Agent incurred in connection with the preparation, administration or interpretation of the Loan Documents and other instruments mentioned herein, each closing hereunder, and amendments, modifications, approvals, consents or waivers hereto or hereunder, (d) the fees, costs, expenses and disbursements of the Agent incurred in connection with the preparation, administration or interpretation of the Loan Documents and other instruments mentioned herein including without limitation, the costs incurred by the Agent in connection with its inspection of the Mortgaged Properties, and the fees and disbursements of the Agent's counsel and the Borrower's legal counsel in preparing documentation, (e) the fees, costs, expenses and disbursements of the Agent incurred in connection with the syndication and/or participation of the Loans, (f) all reasonable out-of-pocket expenses (including reasonable attorneys' fees and costs, which attorneys may be employees of any Bank or the Agent and the fees and costs of appraisers, engineers, investment bankers, surveyors or other experts retained by the Agent or any Bank in connection with any such enforcement proceedings) incurred by any Bank or the Agent in connection with (i) the enforcement of or preservation of rights under any of the Loan Documents against the Borrower or the administration thereof after the occurrence of a Default or Event of Default (including, without limitation, expenses incurred in any restructuring and/or "workout" of the Loans), and (ii) any litigation, proceeding or dispute whether arising hereunder or otherwise, in any way related to the Agent's or the Bank's relationship with the Borrower, the Company, any Permitted Joint Venture or any of the Related Companies, (g) all reasonable fees, expenses and disbursements of the Agent incurred in connection with UCC searches, UCC filings or mortgage recordings, (h) all costs incurred by the Agent in the future in connection with its inspection of the Mortgaged Properties, and (i) the fees, costs, expenses and disbursements of the Agent incurred in connection with the granting of additional Collateral by the Borrower pursuant to 12.5 hereof, including, without limitation, the costs incurred by the Agent in connection with its inspection of such additional Collateral, and the fees and disbursements of the Agent's counsel.
