Subject to the provisions of §2.4 and the other terms and conditions set forth in this Agreement, each of the Lenders severally agrees to lend to the Borrower, and the Borrower may borrow, repay, and reborrow from each Lender from time to time between the Closing Date and the Maturity Date upon notice by the Borrower to the Agent (with copies to the Agent for each Lender) given in accordance with §2.4, 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 Lender’s Commitment minus, without double counting, an amount equal to such Lender’s Commitment Percentage multiplied by the sum of all Reimbursement Obligations to the extent not yet deemed Revolving Credit Loans and the Maximum Drawing Amount; provided that the sum of the outstanding amount of the Revolving Credit Loans (after giving effect to all amounts requested), plus the Maximum Drawing Amount and, without double counting the portion, if any, of any Letter of Credit which is drawn and included in the Revolving Credit Loans, all outstanding Reimbursement Obligations, shall not at any time exceed the lesser of (i) the Total Commitment and (ii) the Availability at such time, and provided, further, that at the time the Borrower requests a Revolving Credit Loan and after giving effect to the making thereof: (i) in the case of any borrowing or other extension of credit, all of the conditions in §13 (and in the case of the initial borrowing on the Closing Date, also the conditions in §12) have been met at the time of such request, and (ii) there has not occurred and is not continuing (or will not occur by reason thereof) any Default or Event of Default.

     The Revolving Credit Loans shall be made pro rata in accordance with each Lender’s Commitment Percentage. Each request for a Revolving Credit Loan made pursuant to §2.4 shall constitute a representation and warranty by the Borrower that the conditions set forth in §12 have been satisfied as of the Closing Date and that the conditions set forth in §13 have been satisfied on the date of such request and will be satisfied on the proposed Drawdown Date of the requested Loan or issuance of Letter of Credit, as the case may be, provided that the making of such representation and warranty by the Borrower shall not limit the right of any Lender not to lend if such conditions have not been met. No Revolving Credit Loan or other extension of credit shall be required to be made by any Lender unless all of the conditions contained in §12 have been satisfied as of the Closing Date with respect to the initial Revolving Credit Loan or issuance of Letter of Credit, and unless all of the conditions set forth in §13 have been satisfied at the time of any request for a Revolving Credit Loan or other extension of credit and on the Drawdown Date therefor.

     §2.2. The Revolving Credit Notes. The Revolving Credit Loans shall be evidenced by the Revolving Credit Notes. A Revolving Credit Note shall be payable to the order of each Lender in an aggregate principal amount equal to such Lender’s Commitment.

The outstanding amount of the Revolving Credit Loans set forth on such applicable Note Record shall be prima facie evidence of the principal amount thereof owing and unpaid to such Lender, but the failure to record, or any error in so recording, any such amount on such Note Record shall not limit or otherwise affect the rights and

18

obligations of the Borrower hereunder or under any Revolving Credit Note to make payments of principal of or interest on any Revolving Credit Note when due.

     §2.3. Interest on Revolving Credit Loans; Fees.

          (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 (unless earlier paid in accordance with §3.2) at a rate equal to the Base Rate plus the Applicable Base Rate Margin.

          (b) Each Libor 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 (unless earlier paid in accordance with §3.2) at a rate equal to the Libor Rate determined for such Interest Period plus the Applicable Libor Margin.

          (c) With reference to Base Rate Loans and Libor Rate Loans, the “Applicable Base Rate Margin” and the “Applicable Libor Margin” shall be equal to (A) from the Closing Date through the end of the fiscal month in which the financial statements required to be delivered pursuant to §8.4(b) for the fiscal quarter of the Borrower ending December 31, 2004 are delivered to the Agent, a percentage equal to 0% for the Applicable Base Rate Margin and 1.70% for the Applicable Libor Margin, and (B) thereafter, the percentage determined for each Rate Period by reference to the Table below:

Table

19

For purposes of determining the Applicable Base Rate Margin and the Applicable Libor Margin, the Consolidated Total Leverage Ratio (§10.1 hereof) will be tested quarterly, commencing with the fiscal quarter of the Borrower ending December 31, 2004, based on the annual or quarterly financial statements required to be delivered pursuant to §8.4(a) or 8.4(b), respectively. For purposes of determining the interest rate for any Rate Period hereunder, any interest rate change shall be effective on the first day of the fiscal month immediately following the date on which the financial statements required to be delivered pursuant to §8.4(a) or §8.4(b) are delivered to the Agent, together with a notice to the Agent (which shall be verified by the Agent) specifying any change in the Applicable Base Rate Margin and/or the Applicable Libor Margin. If the Borrower has failed to timely deliver the financial statements required to be delivered by it pursuant to §8.4(a) or §8.4(b), then in addition to the other rights and remedies of the Lenders hereunder, the Applicable Base Rate Margin and the Applicable Libor Margin that are then in effect shall automatically be increased to the next highest level until such financial statements are delivered.

          (d) The Borrower unconditionally promises to pay interest on each Revolving Credit Loan in arrears on each Interest Payment Date with respect thereto, and when the principal of such Revolving Credit Loan is due (whether at maturity, by reason of acceleration or otherwise).

          (e) The Borrower agrees to pay to the Agent, for the accounts of the Lenders in accordance with their respective Commitment Percentages, from the Closing Date through the Maturity Date, a facility fee (the “Facility Fee”) calculated at the rate of (i) for any day when the outstanding principal balance of the Loans is less than 50% of the Total Commitment, 0.25% per annum, and (ii) for any day when the outstanding principal balance of the Loans is greater than or equal to 50% of the Total Commitment, 0.15% per annum, in each case calculated on the average daily amount, during each fiscal quarter or portion thereof, of the unborrowed portion of the Total Commitment. The Facility Fee shall be payable quarterly in arrears on the fifth Business Day of each calendar quarter for the immediately preceding calendar quarter commencing on the first such date following the Closing Date through the Maturity Date, with a final payment on the Maturity Date.

          (f) The Borrower shall pay to the Agent the following Letter of Credit fees (in each case, a “Letter of Credit Fee”): (i) a fee in an amount equal to the Applicable L/C Percentage of the undrawn amount of each outstanding Letter of Credit, which fee shall be for the accounts of the Lenders (including the Fronting Bank) pro rata in accordance with their respective Commitment Percentages, and (ii) a fee in an amount equal to 0.125% per annum for the account of the Fronting Bank. Each Letter of Credit Fee shall be payable quarterly in arrears on the fifth Business Day of each calendar quarter for the immediately preceding calendar quarter, with a final payment on the Maturity Date or any earlier date on which the Commitments shall terminate (which Letter of Credit Fee shall be pro-rated for any calendar quarter in which such Letter of Credit is issued, drawn upon or otherwise reduced or terminated). In addition, the Borrower shall pay to Issuing Lender for its own account , upon issuance, the standard issuance, documentation and service charges for Letters of Credit issued from time to time by Issuing Lender.

     (iv) No Lender shall be obligated to fund any Revolving Credit Loan unless:

     (a) a Completed Loan Request has been timely received by the Agent as provided in subsection (i) above; and

     (b) both before and after giving effect to the Revolving Credit Loan to be made pursuant to the Completed Loan Request, all of the conditions contained in §12 shall have been satisfied as of the Closing Date, with respect to the initial advance only, and all of the conditions set forth in §13 shall have been met, including, without limitation, the condition under §13.1 that there be no Default or Event of Default under this Agreement.

21

     §2.5. Conversion Options.

          (a) The Borrower may elect from time to time to convert any outstanding Revolving Credit Loan to a Revolving Credit Loan of another Type, provided that (i) subject to the further proviso at the end of this §2.5(a) and subject to §2.5(b) and §2.5(d), with respect to any conversion of a Base Rate Loan to a Libor Rate Loan (or a continuation of a Libor Rate Loan, as provided in §2.5(b)), the Borrower shall give the Agent (with copies to the Agent for each Lender) at least three (3) Business Days’ prior written notice of such election, which such notice must be received by the Agent by 10:00 a.m. on any Business Day; and (ii) no Loan may be converted into a Libor Rate Loan when any Default or Event of Default has occurred and is continuing. All or any part of outstanding Revolving Credit Loans of any Type may be converted as provided herein, provided that each Conversion Request relating to the conversion of a Base Rate Loan to a Libor Rate Loan shall be for an amount equal to $1,000,000 or an integral multiple of $100,000 in excess thereof and shall be irrevocable by the Borrower.

          (b) Any Revolving Credit Loan of any Type may be continued as such upon the expiration of the Interest Period with respect thereto (i) in the case of Base Rate Loans, automatically and (ii) in the case of Libor Rate Loans by compliance by the Borrower with the notice provisions contained in §2.5(a)(i); provided that no Libor 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. The Borrower shall notify the Agent promptly when any such automatic conversion contemplated by this §2.5(b) is scheduled to occur.

Any Loan Request or Conversion Request for a Libor Rate Loan that would create greater than five (5) Libor Rate Loans outstanding shall be deemed to be a Loan Request or Conversion Request for a Base Rate Loan. By way of explanation of the foregoing, in the event that the Borrower wishes to convert or continue two or more Loans into one Libor Rate Loan on the same day and for identical Interest Periods (or borrow an additional Revolving Credit Loan simultaneously with converting or continuing a Revolving Credit Loan for identical Interest Periods), such Libor Rate Loan shall constitute one single Libor Rate Loan for purposes of this clause (d).

     §2.6. Funds for Revolving Credit Loans.

Upon receipt from each Lender of such amount, the Agent will make available to

22

the Borrower the aggregate amount of such Revolving Credit Loan made available to the Agent by the Lenders.

The failure or refusal of any Lender 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 Revolving Credit Loan shall not relieve any other Lender from its several obligation hereunder to make available to the Agent the amount of its Commitment Percentage of any requested Revolving Credit Loan but in no event shall the Agent (in its capacity as Agent) have any obligation to make any funding or shall any Lender be obligated to fund more than its Commitment Percentage of the requested Revolving Credit Loan or to increase its Commitment Percentage on account of such failure or otherwise.

          (b) The Agent may, unless notified to the contrary by any Lender prior to a Drawdown Date, assume that such Lender has made available to the Agent on such Drawdown Date the amount of such Lender’s Commitment Percentage of the Revolving Credit Loan 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 Lender makes available to the Agent such amount on a date after such Drawdown Date, such Lender 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, multiplied by (ii) the amount of such Lender’s Commitment Percentage of such Revolving Credit Loan, multiplied by (iii) a fraction, the numerator of which is the number of days that elapsed from and including such Drawdown Date to the date on which the amount of such Lender’s Commitment Percentage of such Revolving Credit Loan shall become immediately available to the Agent, and the denominator of which is 365. A statement of the Agent submitted to such Lender 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 Lender.

     §2.7. Reduction of Commitment. The Borrower shall have the right at any time and from time to time upon five (5) Business Days’ prior written notice to the Agent (with copies to the Agent for each Lender) to reduce by $5,000,000 or an integral multiple of $1,000,000 in excess thereof (but not below $20,000,000 or, if greater, the Maximum Drawing Amount) or terminate entirely the unborrowed portion of the then Total Commitment, whereupon the Commitments of the Lenders shall be reduced pro rata in accordance with their respective Commitment Percentages by the amount specified in such notice or, as the case may be, terminated. Upon the effective date of any such reduction or termination, the Borrower shall pay to the Agent for the respective accounts of the Lenders all accrued and unpaid interest on the amount of such reduction and the full amount of the Facility Fee then accrued and unpaid on the amount of the reduction. No reduction or termination of the Commitments may be reinstated.

     §2.8. Increase in Total Commitment. At any time (but at least 60 days prior to the Maturity Date), the Borrower shall have the right, upon written notice to the Agent and satisfaction of the Increase Conditions, to cause the Total Commitment to increase by an amount not at any time exceeding $75,000,000 (the “Increase”), in which event Schedule 2 will be deemed to be amended to reflect the increased Commitment of each Lender, if any, that has agreed in writing to an increase and to add any third party financial institution that may have become a party to, and a “Lender” under, this Agreement in connection with the Increase (and

23

the Agent is hereby authorized to effect such amendment on behalf of the Lenders and the Borrower); provided, however, that it shall be a condition precedent to the effectiveness of the Increase that the Increase Conditions shall have been satisfied. In the event that the Increase results in any change to the Commitment Percentage of any Lender, then on the effective date of such Increase in the Total Commitment (i) any new Lender, and any existing Lender whose Commitment has increased, shall pay to the Agent such amounts as are necessary to fund its new or increased Commitment Percentage of all existing Revolving Credit Loans, (ii) the Agent will use the proceeds thereof to pay to all Lenders whose Commitment Percentage is decreasing such amounts as are necessary so that each such Lender’s participation in existing Revolving Credit Loans will be equal to its adjusted Commitment Percentage, and (iii) if the effective date of such Increase in the Total Commitment occurs on a date other than the last day of an Interest Period applicable to any outstanding Libor Rate Loan, the Borrower will be responsible for Libor Breakage Costs and any other amounts payable pursuant to §4.8 on account of the payments made pursuant to clause (ii) above. No Lender shall have any obligation to increase its Commitment in connection with the Increase.

     §2.9. Extension of Revolving Credit Maturity Date. At least 60 days but in no event more than 120 days prior to December 31, 2006, the Borrower, by written notice to the Agent (with copies for each Lender), may request an extension of the Maturity Date by a period of one year from the Maturity Date then in effect (the “Extension”). The Extension shall become effective on December 31, 2006 so long as (i) the Borrower has paid to the Agent on such date, for the ratable accounts of the Lenders, an extension fee in an amount equal to 25 basis points on the Total Commitment in effect on such date, and (ii) no Default or Event of Default has occurred and is continuing on such date and all representations and warranties contained in the Loan Documents are true and correct as of such date (except to the extent that such representations and warranties relate expressly to an earlier date). The notice referred to in the first sentence of this §2.9 shall constitute and shall be deemed to be a certification by the Borrower as to the truth and accuracy of the statements contained in clause (ii) of the preceding sentence.

     §3. REPAYMENT OF THE LOANS.

     §3.1. Maturity. The Borrower promises to pay on the Maturity Date, and there shall become absolutely due and payable on the Maturity Date, all unpaid principal of the Revolving Credit Loans outstanding on such date, together with any and all accrued and unpaid interest thereon, the unpaid balance of the Facility Fee accrued through such date, and any and all other unpaid amounts due under this Agreement, the Notes or any other of the Loan Documents.

     §3.2. Optional Repayments of Revolving Credit Loans. The Borrower shall have the right, at its election, to prepay the outstanding amount of the Revolving Credit Loans, in whole or in part, at any time without penalty or premium; provided that the outstanding amount of any Libor Rate Loans may not be prepaid on a date other than the last day of an Interest Period unless the Borrower pays the Libor Breakage Costs for each Libor Rate Loan so prepaid at the time of such prepayment. The Borrower shall give the Agent (with copies to the Agent for each Lender), no later than 10:00 a.m., Boston, Massachusetts time, at least two (2) Business Days’ prior written notice of any prepayment pursuant to this §3.2 of any Base Rate Loans, and at least four (4) Business Days’ notice of any proposed prepayment pursuant to this §3.2 of Libor Rate Loans, specifying the proposed date of prepayment of Revolving Credit Loans and the principal amount to be prepaid. Each such partial prepayment of the Loans shall be in an amount equal to

24

$1,000,000 or an integral multiple of $1,000,000 in excess thereof or, if less, the outstanding balance of the Revolving Credit Loans then being repaid, shall be accompanied by the payment of all charges, if any, outstanding on all Revolving Credit Loans so prepaid and of all accrued interest on the principal prepaid 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 Libor Rate Loans.

     §3.3 Mandatory Repayment of Loans. If at any time the sum of the outstanding amount of the Loans, plus the Maximum Drawing Amount, plus without double counting any Revolving Credit Loans, the outstanding Reimbursement Obligations, if any, exceeds the lesser of (i) the Total Commitment at such time, or (ii) the Availability at such time, the Borrower shall immediately pay to the Agent an amount in cash necessary to eliminate such excess, such amount to be applied, in the absence of instruction by the Borrower, first to the principal of Base Rate Loans and then to the principal of Libor Rate Loans.

     §4. CERTAIN GENERAL PROVISIONS.

     §4.1. Funds for Payments.

          (a) All payments of principal, interest, fees, and any other amounts due hereunder or under any of the other Loan Documents shall be made to the Agent, for the respective accounts of the Lenders or (as the case may be) the Agent, at the Agent’s Head Office, in each case in Dollars and in immediately available funds. The Borrower shall make each payment of principal of and interest on the Loans and Reimbursement Obligations which are not converted to a Loan hereunder and of fees hereunder not later than 12:00 p.m. (Boston, Massachusetts time) on the due date thereof.

          (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 the Borrower is compelled by law to make any such deduction or withholding with respect to any amount payable by it hereunder or under any of the other Loan Documents (except with respect to taxes on the income or profits of the Agent or any Lender), the Borrower shall pay to the Agent, for the account of the Lenders 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 Lenders to receive the same net amount which the Lenders would have received on such due date had no such deduction or withholding obligation been imposed upon the Borrower. The Borrower will deliver promptly to the Agent (with copies to the Agent for each Lender) 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.

     §4.2. Computations. All computations of interest on Libor Rate Loans and of other fees to the extent applicable shall be based on a 360-day year and all computations of interest on Base Rate Loans shall be based on a 365/366 day year, in each case paid for the actual number of days elapsed. Except as otherwise provided in the definition of the term “Interest Period” with respect

25

to Libor 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 Note Records or record attached to any other Note from time to time shall constitute prima facie evidence of the principal amount thereof.

     §4.3. Inability to Determine Libor Rate. In the event, prior to the commencement of any Interest Period relating to any Libor Rate Loan, the Agent shall determine that adequate and reasonable methods do not exist for ascertaining the Libor Rate that would otherwise determine the rate of interest to be applicable to any Libor Rate Loan during any Interest Period, the Agent shall forthwith give notice of such determination (which shall be conclusive and binding on the Borrower) to the Borrower and the Lenders. In such event (a) any Loan Request with respect to Libor Rate Loans shall be automatically withdrawn and shall be deemed a request for Base Rate Loans, (b) each Libor Rate Loan will automatically, on the last day of the then current Interest Period applicable thereto, become a Base Rate Loan, and (c) the obligations of the Lenders to make Libor Rate Loans shall be suspended, in each case unless and until the Agent determines that the circumstances giving rise to such suspension no longer exist, whereupon the Agent shall so notify the Borrower and the Lenders.

     §4.4. Illegality. Notwithstanding any other provisions herein, if any present or future law, regulation, treaty or directive or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Libor Rate Loans, such Lender shall forthwith give notice of such circumstances to the Agent and the Borrower and thereupon (a) the Commitment of such Lender to make Libor Rate Loans or convert Base Rate Loans to Libor Rate Loans shall forthwith be suspended and (b) such Lender’s Commitment Percentage of Libor Rate Loans then outstanding shall be converted automatically to Base Rate Loans on the last day of each Interest Period applicable to such Libor Rate Loans or within such earlier period as may be required by law, all until such time as it is no longer unlawful for such Lender to make or maintain Libor Rate Loans. The Borrower hereby agrees promptly to pay the Agent for the account of such Lender, upon demand, any additional amounts necessary to compensate such Lender for Libor Breakage Costs incurred by such Lender in making any conversion required by this §4.4 prior to the last day of an Interest Period.

     §4.5. Additional Costs, Etc. If any present or future applicable law, which expression, as used herein, includes statutes, rules and regulations thereunder and interpretations thereof by any competent court or by any governmental or other regulatory body or official charged with the administration or the interpretation thereof and requests, directives, instructions and notices at any time or from time to time hereafter made upon or otherwise issued to any Lender or the Agent by any central bank or other fiscal, monetary or other authority (whether or not having the force of law, but if not having the force of law, then generally applied by the Lenders or the Agent with respect to similar loans), shall:

          (a) subject any Lender or the Agent to any tax, levy, impost, duty, charge, fee, deduction or withholding of any nature with respect to this Agreement, the other Loan Documents, any Letters of Credit, such Lender’s Commitment or the Loans (other than taxes based upon or measured by the income or profits of such Lender or the Agent), or

26

          (b) change the basis of taxation (except for changes in taxes on income or profits) of payments to any Lender of the principal of or the interest on any Loans or any other amounts payable to the Agent or any Lender under this Agreement or the other Loan Documents, or

          (c) impose or increase or render applicable (other than to the extent specifically provided for elsewhere in this Agreement) any special deposit, reserve, assessment, liquidity, capital adequacy or other similar requirements (whether or not having the force of law) against assets held by, or deposits in or for the account of, or loans by, or letters of credit issued by, or commitments of an office of any Lender, or

          (d) impose on any Lender or the Agent any other conditions or requirements with respect to this Agreement, the other Loan Documents, the Loans, such Lender’s Commitment, or any class of loans or commitments of which any of the Loans or such Lender’s Commitment forms a part;

and the result of any of the foregoing is

     (i) to increase the cost to any Lender of making, funding, issuing, renewing, extending or maintaining any of the Loans or such Lender’s Commitment or any Letter of Credit, or

     (ii) to reduce the amount of principal, interest, Reimbursement Obligation or other amount payable to such Lender or the Agent hereunder on account of such Lender’s Commitment, any Letter of Credit or any of the Loans, or

     (iii) to require such Lender or the Agent to make any payment or to forego any interest or Reimbursement Obligation or other sum payable hereunder, the amount of which payment or foregone interest or Reimbursement Obligation or other sum is calculated by reference to the gross amount of any sum receivable or deemed received by such Lender or the Agent from the Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by the Agent or such Lender (such demand to be made promptly by the Agent or such Lender upon the making of any such determination), at any time and from time to time and as often as the occasion therefor may arise, pay to such Lender or the Agent such additional amounts as such Lender or the Agent shall determine in good faith to be sufficient to compensate such Lender or the Agent for such additional cost, reduction, payment or foregone interest or other sum, provided that such Lender or the Agent is generally imposing similar charges on its other similarly situated borrowers. The Agent shall provide the Borrower with a calculation, in reasonable detail, of such amounts in accordance with its customary practices.

     §4.6. Capital Adequacy. If any future law, governmental rule, regulation, policy, guideline or directive (whether or not having the force of law, but if not having the force of law, then generally applied by the Lenders with respect to similar loans) or the interpretation thereof by a court or governmental authority with appropriate jurisdiction affects the amount of capital required or expected to be maintained by banks or bank holding companies and any Lender or the Agent determines that the amount of capital required to be maintained by it is increased by or

27

based upon the existence of Loans made or deemed to be made pursuant hereto, then such Lender or the Agent may notify the Borrower of such fact, and the Borrower shall pay to such Lender or the Agent from time to time, upon demand made by the Agent or such Lender (such demand to be made promptly by the Agent or such Lender upon the making of any such determination), as an additional fee payable hereunder, such amount as such Lender or the Agent shall determine reasonably and in good faith and certify in a notice to the Borrower to be an amount that will adequately compensate such Lender in light of these circumstances for its increased costs of maintaining such capital. Each Lender and the Agent shall allocate such cost increases among its customers in good faith and on an equitable basis, and will not charge the Borrower unless it is generally imposing a similar charge on its other similarly situated borrowers. The Agent shall provide the Borrower with a calculation, in reasonable detail, of such amounts in accordance with its customary practices.

     §4.7. Certificate; Limitations. A certificate setting forth any additional amounts payable pursuant to §§4.5 or 4.6 and a brief explanation of such amounts which are due, submitted by any Lender or the Agent to the Borrower, shall be prima facie evidence that such amounts are due and owing. Notwithstanding anything to the contrary contained in this Article 5, to the extent reasonably possible, each Lender shall designate an alternate lending office in the continental United States to make the Loans in order to reduce any liability of Borrower to such Lender under §§4.4, 4.5 or 4.6 or to avoid the unavailability of a Libor Rate Loan, so long as such designation is not disadvantageous to such Lender.

     §4.8. Indemnity. In addition to the other provisions of this Agreement regarding such matters, the Borrower agrees to indemnify the Agent and each Lender and to hold the Agent and each Lender harmless from and against any loss, cost or expense (including loss of anticipated profits) that the Agent or such Lender may sustain or incur as a consequence of (a) a default by the Borrower in the payment of any principal amount of or any interest on any Libor Rate Loans as and when due and payable, including any such loss or expense arising from interest or fees payable by the Agent or such Lender to lenders of funds obtained by it in order to maintain its Libor Rate Loans, (b) the failure by the Borrower to make a borrowing or conversion after the Borrower has given a Completed Loan Request for a Libor Rate Loan or a Conversion Request for a Libor Rate Loan, and (c) the making of any payment of a Libor Rate Loan or the making of any conversion of any such Loan to a Base Rate Loan on a day that is not the last day of the applicable Interest Period with respect thereto, including interest or fees payable by the Agent or a Lender to lenders of funds obtained by it in order to maintain any such Libor Rate Loans.

     §4.9. Interest on Overdue Amounts; Late Charge. Notwithstanding anything to the contrary stated herein, upon the occurrence and during the continuance of an Event of Default, at the option of the Majority Lenders, to the extent permitted by applicable law, the unpaid balance of all Obligations shall bear interest at the rate otherwise applicable thereto plus 2%, compounded daily until such Event of Default is cured or waived to the satisfaction of the Agent and the required Lenders. In addition, the Borrower shall pay a late charge equal to five percent (5%) of any amount of interest charges on the Loans which is not paid within ten (10) days of the date when due.

     §5. LETTERS OF CREDIT.

28

     §5.1. Letter of Credit Commitments.

          §5.1.1. Commitment to Issue Letters of Credit. Subject to the terms and conditions set forth in this Agreement, at any time and from time to time from the Closing Date through the day that is one-hundred twenty (120) days prior to the Maturity Date, the Issuing Lender shall issue such Letters of Credit as the Borrower may request upon the delivery of a written request on the Fronting Bank’s customary form as part of a Completed Loan Request (a “Letter of Credit Application”), the Fronting Bank on behalf of the Lenders and in reliance upon the agreement of the Lenders set forth in §5.1.4 and upon the representations and warranties of the Borrower contained herein, agrees, in its individual capacity, to issue, extend and renew for the account of the Borrower one or more letters of credit (individually, a “Letter of Credit”), in such form as may be requested from time to time by the Borrower and agreed to by the Fronting Bank; provided, however, that, after giving effect to such Completed Loan Request, (a) the Maximum Drawing Amount plus all Reimbursement Obligations (to the extent, if any, not yet deemed a Revolving Credit Loan pursuant to §5.3), shall not exceed $10,000,000 at any one time and (b) the sum of (i) the Maximum Drawing Amount and, without double counting, all Reimbursement Obligations (to the extent, if any, not yet deemed a Revolving Credit Loan pursuant to §5.3) and (ii) the amount of all Loans outstanding shall not exceed the lesser of (x) the Total Commitment in effect at such time and (y) the Availability at such time.

     Each Letter of Credit Application shall be executed by an officer of Borrower. The Issuing Lender shall be entitled to conclusively rely on such Person’s authority to request a Letter of Credit on behalf of Borrower. The Issuing Lender shall have no duty to verify the authenticity of any signature appearing on a Letter of Credit Request. The Borrower assumes all risks with respect to the use of the Letters of Credit. Unless the Issuing Lender and the Required Lenders otherwise consent, the term of any Letter of Credit shall not exceed a period of time commencing on the issuance of the Letter of Credit and ending on the date which is sixty (60) days prior to the Maturity Date (but in any event the term shall not extend beyond the Maturity Date). The amount available to be drawn under any Letter of Credit shall reduce on a dollar-for-dollar basis the amount available to be drawn under the Total Commitment as a Loan. Each Letter of Credit Application shall be submitted to the Issuing Lender at least ten (10) Business Days (or such shorter period as the Issuing Lender may approve) prior to the date upon which the requested Letter of Credit is to be issued. Each such Letter of Credit Application 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 the chief financial or chief accounting officer of Borrower that the Borrower is and will be in compliance with all covenants under the Loan Documents after giving effect to the issuance of such Letter of Credit. The Borrower 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. The Issuing Lender shall, if it approves of the content of the Letter of Credit request (which approval shall not be unreasonably withheld), and subject to the conditions set forth in this Agreement, issue the Letter of Credit on or before ten (10) Business Days following receipt of the documents last due pursuant to §2.10(b). Each Letter of Credit shall be in form and substance reasonably satisfactory to the Issuing Lender in its reasonable discretion. 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. Upon the issuance of a Letter of Credit, each Revolving Credit Lender shall be deemed to have

29

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. The issuance of any supplement, modification, amendment, renewal or extension to or of any Letter of Credit shall be treated in all respects the same as the issuance of a new Letter of Credit.

          §5.1.2. Letter of Credit Applications. Each Letter of Credit Application shall be completed to the satisfaction of the Agent and the Fronting Bank.

          §5.1.3. Terms of Letters of Credit. Each Letter of Credit issued, extended or renewed hereunder shall, among other things, (i) provide for the payment of sight drafts for honor thereunder when presented in accordance with the terms thereof and when accompanied by the documents described therein, and (ii) shall have an expiry date no later than one year after its issuance. Each Letter of Credit so issued, extended or renewed shall be subject to the Uniform Customs.

          §5.1.4. Obligations of Lenders with respect to Letters of Credit. Each Lender severally agrees that it shall be absolutely liable, without regard to the occurrence of any Default or Event of Default or any other condition precedent whatsoever, to the extent of such Lender’s Commitment Percentage, to reimburse the Fronting Bank on demand for the amount of each draft paid by the Fronting Bank under each Letter of Credit (such agreement for a Lender being called herein the “Letter of Credit Participation” of such Lender). Each such payment made by a Lender shall be treated as a purchase by such Lender of a participation in the Fronting Bank’s interest in such Letter of Credit and each Lender shall share, in accordance with its respective Commitment Percentage, in any interest (but not any fee payable solely for the account of the Fronting Bank) which accrues and is payable by the Borrower pursuant to §5.2 or otherwise in connection with such Letter of Credit.

          §5.2. Reimbursement Obligation of the Borrower. In order to induce the Fronting Bank to issue, extend and renew each Letter of Credit and the Lenders to participate therein, the Borrower hereby agrees to reimburse or pay to the Fronting Bank, for the account of the Fronting Bank or (as the case may be) the Lenders, with respect to each Letter of Credit issued, extended or renewed by the Fronting Bank hereunder,

          (a) promptly upon notification by the Fronting Bank or the Agent that any draft presented under such Letter of Credit is honored by the Fronting Bank, or the Fronting Bank otherwise makes a payment with respect thereto, (i) the amount paid by the Fronting Bank under or with respect to such Letter of Credit, and (ii) any amounts payable pursuant to §5.5 under, or with respect to, such Letter of Credit, and

          (b) upon the termination of the Total Commitment, or the acceleration of the Reimbursement Obligations with respect to all Letters of Credit in accordance with §14, an amount equal to the then Maximum Drawing Amount on all Letters of Credit, which amount shall be held by the Agent in an interest-bearing account (with interest to be added to such account) as cash collateral for the benefit of the Lenders and the Agent for all Reimbursement Obligations. Upon the expiration, termination or surrender without draw of any Letter of Credit, the Agent shall release to the Borrower the cash collateral amount applicable to such Letter of Credit.

30

     Each such payment shall be made to the Agent for the benefit of the Fronting Bank or the Lenders, as applicable, at the Agent’s Head Office in immediately available funds. Interest on any and all amounts not converted to a Revolving Credit Loan pursuant to §5.3 and remaining unpaid by the Borrower under this §5.2 at any time from the date such amounts become due and payable (whether as stated in this §5.2, by acceleration or otherwise) until payment in full (whether before or after judgment) shall be payable to the Agent for the benefit of the Lenders on demand at the rate specified in §4.9 for overdue principal on the Loans.

     §5.3. Letter of Credit Payments; Funding of a Loan. If any draft shall be presented or other demand for payment shall be made under any Letter of Credit, the Fronting Bank will use its reasonable efforts to notify the Borrower and the Lenders, on or before the date the Fronting Bank intends to honor such drawing, of the date and amount of the draft presented or demand for payment and of the date and time when it expects to pay such draft or honor such demand for payment and, except to the extent the amount of such draft becomes a Revolving Credit Loan as set forth in this §5.3, Borrower shall reimburse Agent, as set forth in §5.2. Notwithstanding anything contained in §5.2 or this §5.3 to the contrary, however, unless Borrower shall have notified the Agent and Fronting Bank prior to 11:00 a.m. (New York time) on the Business Day immediately prior to the date of such drawing that Borrower intends to reimburse Fronting Bank for the amount of such drawing with funds other than the proceeds of Revolving Credit Loans, Borrower shall be deemed to have timely given a Completed Loan Request pursuant to §2.4 to Agent, requesting a Base Rate Loan on the date on which such drawing is honored and in an amount equal to the amount of such drawing. The Borrower may thereafter convert any such Base Rate Loan to a Revolving Credit Loan of another Type in accordance with §2.5. Each Lender shall, in accordance with §2.6, make available such Lender’s Commitment Percentage of such Revolving Credit Loan to Agent, the proceeds of which shall be applied directly by Agent to reimburse Fronting Bank for the amount of such draw. In the event that any Lender fails to make available to Agent the amount of such Lender’s Commitment Percentage of such Revolving Credit Loan on the date of any drawing, Agent shall be entitled to recover such amount on demand from such Lender plus any additional amounts payable under §2.6(b) in the event of a late funding by a Lender. 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 until such amount has been funded (as a result of such assignment or otherwise). If after the issuance of a Letter of Credit pursuant to §2.10(c) by the Issuing Lender, but prior to the funding of any portion thereof by a Lender, one of the events described in §14.1(g) or (h) shall have occurred, each Lender will, on the date such Revolving Credit Loan was to have been made, purchase an undivided participation interest in the Letter of Credit in an amount equal to its 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. The Fronting Bank is irrevocably authorized by the Borrower and each of the Lenders to honor draws on each Letter of Credit by the beneficiary thereof in accordance with the terms of such Letter of Credit. The responsibility of the Fronting Bank to the Borrower and the Lenders shall be only to determine that the documents (including each draft) delivered under each Letter of Credit in connection with such presentment shall be in conformity in all material respects with such Letter of Credit in accordance with the Fronting Bank’s customary practices.

31

     §5.4. Obligations Absolute.

In this regard, the Lenders and the Agent intend that this transaction will not be a “confidential transaction” under Code sections 6011, 6111 or 6112, and the regulations promulgated thereunder. Neither Borrower, any Guarantor, nor any Subsidiary of any of the foregoing intends to treat the Loan or the transactions contemplated by this Agreement and the other Loan Documents as being a “reportable transaction” (within the meaning of Treasury Regulation Section 1.6011-4). If the Borrower or the Guarantor determines to take any action inconsistent with such intention, the Borrower will promptly notify the Agent thereof. If the Borrower so notifies the Agent, the Borrower acknowledges that the Agent may treat the Loan as part of a transaction that is subject to Treasury Regulation Section  ###-###-####-1, and the Agent will maintain the lists and other records, including the identity of the applicable party to the Loan as required by such Treasury Regulation.

     §8.11. Compliance with Laws, Contracts, Licenses, and Permits. The Borrower and the Trust will comply with, and will cause each of their respective Subsidiaries to comply with (a) all applicable laws and regulations now or hereafter in effect wherever its business is conducted that are material in any respect to the operation of their respective businesses in the ordinary course and consistent with past practices, including, without limitation, all such Environmental Laws and all such applicable federal and state securities laws, (b) the provisions of its partnership agreement or corporate charter and other Organizational Documents, as applicable, (c) all material agreements and instruments to which it is a party or by which it or any of its properties may be bound (including the Real Estate Assets and the Leases) and (d) all applicable decrees, orders, and judgments. If at any time while any Loan or Note or other Obligations is outstanding or the Lenders have any obligation to make Loans or issue Letters of Credit

46

hereunder, any Permit shall become necessary or required in order that the Borrower may fulfill any of its obligations hereunder, the Borrower and the Trust and their respective Subsidiaries will immediately take or cause to be taken all reasonable steps within the power of the Borrower or the Trust, as applicable, to obtain such Permit and furnish the Agent with evidence thereof.

     §8.12. Use of Proceeds. Subject at all times to the other provisions of this Agreement, including without limitation §7.17, the Borrower will use the proceeds of the Loans solely to repay in full its obligations under its existing revolving credit facility agented by Fleet National Bank, to finance acquisitions and rehabilitation of Permitted Properties and for its working capital and general corporate purposes.

     §8.13. Additional Borrower; Solvency of Borrower; Removal of Borrower; Addition of Real Estate Asset to Unencumbered Pool.

          (a) If, after the Closing Date, FPLP wishes to designate as an Eligible Unencumbered Property a Real Estate Asset that otherwise qualifies as an Eligible Unencumbered Property but is owned by a Person other than the Borrower, FPLP shall cause such Person (which Person must be a Wholly-owned Subsidiary of FPLP) to become a party to this Agreement and the other applicable Loan Documents prior to such Real Estate Asset becoming an Eligible Unencumbered Property hereunder. The liability of each Person which is from time to time a Borrower hereunder shall be joint and several with each other Borrower for all Obligations for so long as such Borrower is a Borrower hereunder (provided that FPLP shall at all times be a Borrower hereunder). In accordance with §11.3, at any time and from time to time but only for so long as no Default or Event of Default shall then exist, FPLP may notify Agent, in writing (each, a “Release Notice”), that the Borrower would like one (1) or more Eligible Unencumbered Properties to be removed from the Unencumbered Pool. Such Release Notice shall be accompanied by a Certificate of Compliance in the form of Exhibit C-3, evidencing compliance with §2.1 and §10 after giving effect to the requested release. Upon the Agent’s receipt of such Release Notice and its satisfaction with the Certificate of Compliance, such Eligible Unencumbered Properties (each, a “Released Property”) shall be removed from the Unencumbered Pool and any Wholly-owned Subsidiary which is the owner of a Released Property (and is not the owner of any other an Eligible Unencumbered Property) and which is then a Borrower (other than FPLP) hereunder shall be released from its obligations hereunder (including the Obligations). FPLP will not permit any Borrower (other than FPLP) that owns any Eligible Unencumbered Property to have any Subsidiaries unless such Subsidiary’s business, obligations and undertakings are exclusively related to the business of such Borrower.

          (b) The Borrower and the Trust shall remain solvent at all times.

          (c) Prior to the addition of any Real Estate Asset to the Unencumbered Pool, the Borrower shall deliver to the Agent (i) a written request to add such Real Estate Asset to the Unencumbered Pool, (ii) the Joinder Documents, if applicable, (iii) a current rent roll and operating statement for such Real Estate Asset, (iv) a Certificate of Compliance in the form of Exhibit C-3 evidencing compliance with §2.1 and §10 after giving effect to the requested addition, (v) a certification that such Real Estate Asset is not the subject of a Disqualifying Environmental Event or a Disqualifying Structural Event, and (vi) any other documents, certificates, instruments or agreements reasonably requested by the Agent.

47

          (d) Notwithstanding the foregoing clauses (a) — (c) or any other provision of this Agreement, until such time as the Unencumbered Pool has at least 4 Eligible Unencumbered Properties and an aggregate value of at least $60,000,000, (i) the addition of any new Eligible Unencumbered Property to the Unencumbered Pool, (ii) the addition of any Borrower, (iii) the removal of any Real Estate Asset from the Unencumbered Pool or (iv) the release of any Borrower shall require the prior written consent of the Majority Lenders. In addition, in the event the Borrower wishes to add a Real Estate Asset to the Unencumbered Pool which does not meet one or more of the Unencumbered Property Conditions or the provisions of §8.13(c), such Real Estate Asset may be included in the Unencumbered Pool with Unanimous Lender Approval. From and after the first date on which the Unencumbered Pool has at least 4 Eligible Unencumbered Properties having an aggregate value of at least $60,000,000, the Borrower shall at all times maintain at least 4 Eligible Unencumbered Properties having an aggregate value of at least $60,000,000 in the Unencumbered Pool.

     §8.14. Further Assurances. The Borrower and the Trust will cooperate with the Agent and the Lenders and execute such further instruments and documents as the Lenders or the Agent shall reasonably request to carry out to their satisfaction the transactions contemplated by this Agreement and the other Loan Documents.

     §8.15. Interest Rate Protection. In the event that the Borrower’s floating rate Indebtedness that is not otherwise subject to interest rate protection arrangements at any time exceeds twenty-five percent (25%) of Consolidated Total Indebtedness for borrowed money, the Borrower shall obtain and maintain in effect interest rate protection arrangements (by means of hedging techniques or vehicles such as interest rate swaps, interest rate caps, interest rate corridors or interest rate collars, in each case to be capped at a rate reasonably satisfactory to the Agent and otherwise in form and substance reasonably satisfactory to the Agent) for a term and in an amount reasonably satisfactory to the Agent. Once obtained, the Borrower shall maintain such arrangements in full force and effect as provided therein, and shall not, without the approval of the Agent, modify, terminate, or transfer such arrangements during the period in which the Borrower’s floating rate Indebtedness exceeds twenty-five percent (25%) of Consolidated Total Indebtedness for borrowed money.

     §8.16. Environmental Indemnification. The Borrower and the Trust each covenants and agrees that it will indemnify and hold the Agent and each Lender, and each of their respective Affiliates, harmless from and against any and all claims, expense, damage, loss or liability incurred by the Agent or any Lender (including all reasonable costs of legal representation incurred by the Agent or any Lender, but excluding, as applicable, for the Agent or a Lender any claim, expense, damage, loss or liability as a result of the gross negligence or willful misconduct of the Agent or such Lender or any of their respective Affiliates) relating to (a) any Release or threatened Release of Hazardous Substances on any Real Estate Asset; (b) any violation of any Environmental Laws with respect to conditions at any Real Estate Asset or the operations conducted thereon; (c) the investigation or remediation of off-site locations at which the Borrower, the Trust or any of their respective Subsidiaries or their predecessors are alleged to have directly or indirectly disposed of Hazardous Substances; or (d) any action, suit, proceeding or investigation brought or threatened with respect to any Hazardous Substances relating to Real Estate Assets (including, but not limited to, claims with respect to wrongful death, personal injury or damage to property). It is expressly acknowledged by the Borrower that, notwithstanding the introductory paragraph of this §8, this covenant of indemnification shall survive the repayment of the amounts owing under the Notes and this Agreement and the

48

termination of this Agreement and the obligations of the Lenders hereunder and shall inure to the benefit of the Agent and the Lenders and their respective Affiliates, their respective successors, and their respective assigns under the Loan Documents permitted under this Agreement.

     §8.17. Response Actions. The Borrower covenants and agrees that if any Release or disposal of Hazardous Substances shall occur or shall have occurred on any Real Estate Asset owned directly or indirectly by the Borrower or the Trust, in violation of applicable Environmental Laws, the Borrower will cause the prompt containment and removal of such Hazardous Substances and remediation of such wholly-owned Real Estate Asset as necessary to comply with all Environmental Laws or to preserve the value of any applicable Eligible Unencumbered Property.

     §8.18. Environmental Assessments. If the Agent reasonably believes, after discussion with the Borrower and review of any environmental reports provided by the Borrower, that a Disqualifying Environmental Event has occurred with respect to any one or more of the Eligible Unencumbered Properties, whether or not a Default or an Event of Default shall have occurred, the Agent may, from time to time, for the purpose of assessing and determining whether a Disqualifying Environmental Event has in fact occurred, cause the Borrower to obtain one or more environmental assessments or audits of such Eligible Unencumbered Property prepared by a hydrogeologist, an independent engineer or other qualified consultant or expert approved by the Agent to evaluate or confirm (i) whether any Hazardous Substances are present in the soil or water at such Eligible Unencumbered Property and (ii) whether the use and operation of such Eligible Unencumbered Property complies with all Environmental Laws. Environmental assessments may include without limitation detailed visual inspections of such Eligible Unencumbered Property including, without limitation, any and all storage areas, storage tanks, drains, dry wells and leaching areas, and, if and to the extent reasonable, appropriate and required pursuant to applicable Environmental Laws, the taking of soil samples, surface water samples and ground water samples, as well as such other investigations or analyses as the Agent deems appropriate. All such environmental assessments shall be at the sole cost and expense of the Borrower.

     §8.19. Employee Benefit Plans.

          (a) Notice. The Borrower and the Trust will notify the Agent (with copies to the Agent for each Lender) at least thirty (30) days prior to the establishment of any Employee Benefit Plan, Multiemployer Plan or Guaranteed Pension Plan by any of them or any of their respective ERISA Affiliates other than those disclosed on Schedule 8.19 attached hereto or disclosed in the SEC Filings, and neither the Borrower nor the Trust will establish any Employee Benefit Plan, Multiemployer Plan or Guaranteed Pension Plan which could reasonably be expected to have a material adverse effect on FPLP, the Trust or any member of the Potomac Group.

          (b) In General. Each Employee Benefit Plan maintained by the Borrower, the Trust or any of their respective ERISA Affiliates will be operated in compliance with the provisions of ERISA and, to the extent applicable, the Code, including but not limited to the provisions thereunder respecting prohibited transactions.

          (d) Unfunded or Underfunded Liabilities. The Borrower and the Trust will not at any time have accruing or accrued unfunded or underfunded liabilities with respect to any Employee Benefit Plan, Guaranteed Pension Plan or Multiemployer Plan, or permit any condition to exist under any Multiemployer Plan that would create a withdrawal liability.

          (k) any “Event of Default” or default (after notice and expiration of any period of grace, to the extent provided, as defined or provided in any of the other Loan Documents, shall occur and be continuing;

          (l) with respect to any Guaranteed Pension Plan, an ERISA Reportable Event shall have occurred and the Majority Lenders shall have determined in their reasonable discretion that such event reasonably could be expected to result in liability of the Borrower or any of its Subsidiaries or the Trust or any of its Subsidiaries to the PBGC or such Guaranteed Pension Plan in an aggregate amount exceeding $1,000,000 and such event in the circumstances occurring reasonably could constitute grounds for the termination of such Guaranteed Pension Plan by the PBGC or for the appointment by the appropriate United States District Court of a trustee to administer such Guaranteed Pension Plan; or a trustee shall have been appointed by the United States District Court to administer such Plan; or the PBGC shall have instituted proceedings to terminate such Guaranteed Pension Plan;

          (m) subject to the Borrower’s ability to remove Real Estate Assets from the Unencumbered Pool in accordance with the provisions set forth below in this §14, the failure of any of the Real Estate Assets being included from time to time as part of the Unencumbered Pool to comply with any of the conditions set forth in the definition of Eligible Unencumbered Properties;

          (n) the failure of any two of (i) Douglas Donatelli, for any reason, to cease to retain the titles of President, Chief Executive Officer and Trustee of the Trust, or (ii) Nicholas R. Smith, for any reason, to cease to retain the titles of Executive Vice President and Chief Investment Officer, or (iii) Barry H. Bass, for any reason, to cease to retain the titles of Senior Vice President and Chief Financial Officer, and in each case, to perform the functions typically performed under such respective offices and to be actively involved in strategic planning and decision-making for the Trust, unless within six (6) months after such failure, the Board of Directors or Board of Trustees has duly elected or appointed a qualified substitute to replace such individual who is acceptable to the Majority Lenders in their sole discretion (as notified to the Borrower by the Agent in writing); or the occurrence of any transaction in which any “person” or “group” (within the meaning of Section 13(d) and 14(d)(2) of the Securities Exchange Act of 1934) becomes the “beneficial owner” (as defined in Rule 13d-3 under the

61

Securities Exchange Act of 1934), directly or indirectly, of a sufficient number of shares of all classes of stock then outstanding of the Trust ordinarily entitled to vote in the election of directors, empowering such “person” or “group” to elect a majority of the Board of Directors or Board of Trustees of the Trust, who did not have such power before such transaction; or during any twelve-month period on or after the Closing Date, individuals who at the beginning of such period constituted the Board of Trustees of the Trust (together with any new directors whose election by the Board of Trustees or whose nomination for election by the shareholders of the Trust was approved by a vote of at least a majority of the members of the Board of Trustees then in office who either were members of the Board of Trustees at the beginning of such period or whose election or nomination for election was previously so approved) ceased for any reason to constitute a majority of the members of the Board of Trustees of the Trust then in office; or

          (o) without limitation of the other provisions of this §14.1, the Trust shall at any time fail to be the sole general partner of FPLP or shall at any time be in contravention of any of the requirements contained in the last paragraph of §9.2 hereof, or §9.3 (including, without limitation, the last paragraph of §9.3);

          then, and in any such event, so long as the same may be continuing, the Agent may, and upon the request of the Majority Lenders shall, declare all amounts owing with respect to this Agreement, the Notes and the other Loan Documents to be, and they shall thereupon forthwith become, immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived by the Borrower, the Trust and each of their respective Subsidiaries; provided that in the event of any Event of Default specified in §14.1(g) or 14.1(h), all such amounts shall become immediately due and payable automatically and without any requirement of notice from any of the Lenders or the Agent or action by the Lenders or the Agent.

     Notwithstanding the foregoing provisions of this §14.1, in the event of a Default or Event of Default arising as a result of the inclusion of any Real Estate Asset in the Unencumbered Pool at any particular time of reference, if such Default or Event of Default is capable of being cured by the exclusion of such Real Estate Asset from the Unencumbered Pool in accordance with, and subject to, §8.13 and from all other covenant calculations under §10 or otherwise, the Borrower shall be permitted a period not to exceed five (5) days to submit to the Agent (with copies to the Agent for each Bank) a compliance certificate in the form of Exhibit C hereto evidencing compliance with §2.1 and with all of the covenants set forth in §10 (with calculations evidencing such compliance after excluding from Adjusted Net Operating Income all of the Adjusted Net Operating Income generated by the Real Estate Asset to be excluded from the Unencumbered Pool) and with the Unencumbered Property Conditions, and otherwise certifying that, after giving effect to the exclusion of such Real Estate Asset from the Unencumbered Pool, no Default or Event of Default will be continuing.

     §14.2. Termination of Commitments. If any one or more Events of Default specified in §14.1(g) or §14.1(h) shall occur, any unused portion of the Commitments or other commitments to extend credit hereunder shall forthwith terminate and the Lenders shall be relieved of all obligations to make Loans to the Borrower and the Agent and the Fronting Bank shall be relieved of all further obligations to issue, extend or renew Letters of Credit. If any other Event of Default shall have occurred and be continuing, the Agent may, and upon the request of the Majority Lenders shall, terminate the unused portion of the Commitments or other commitment to extend credit hereunder. No such termination of the Commitments or other commitment to

62

extend credit hereunder shall relieve the Borrower of any of the Obligations or any of its existing obligations to the Agent or the Lenders arising under other agreements or instruments.

     §14.3. Remedies. In the event that one or more Events of Default shall have occurred and be continuing, whether or not the Lenders shall have accelerated the maturity of the Loans pursuant to §14.1, the Majority Lenders may direct the Agent to proceed to protect and enforce the rights and remedies of the Agent and the Lenders under this Agreement, the Notes, any or all of the other Loan Documents or under applicable law by suit in equity, action at law or other appropriate proceeding (including for the specific performance of any covenant or agreement contained in this Agreement or the other Loan Documents or any instrument pursuant to which the Obligations are evidenced and, to the full extent permitted by applicable law, the obtaining of the ex parte appointment of a receiver), and, if any amount shall have become due, by declaration or otherwise, proceed to enforce the payment thereof or any other legal or equitable right or remedy of the Agent and the Lenders under the Loan Documents or applicable law. No remedy herein conferred upon the Lenders or the Agent or the holder of any Note or purchaser of any Letter of Credit Participation is intended to be exclusive of any other remedy and each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder or under any of the other Loan Documents or now or hereafter existing at law or in equity or by statute or any other provision of law.

     §15. SECURITY INTEREST AND SET-OFF.

     §15.1 Security Interest. Borrower hereby grants to the Agent, on behalf of and for the benefit of the Lenders, and to each Lender, a lien, security interest and right of setoff as security for all liabilities and obligations to the Lenders, 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 the Agent or any Lender or any entity under the control of KeyCorp. and its successors and assigns, or in transit to any of them.

     §15.2 Set-Off and Debit. (i) If any Event of Default or other event which would entitle the Agent to accelerate the Loans occurs, or (ii) at any time, whether or not any Default or Event of Default exists, in the event any attachment, trustee process, garnishment, or other levy or lien is, or is sought to be, imposed on any property of the Borrower; then, in any such event, any such deposits, balances or other sums credited by or due from the Agent or any Lender, or from any such affiliate of the Agent or any Lender, to the Borrower may to the fullest extent not prohibited by applicable law at any time or from time to time, without regard to the existence, sufficiency or adequacy of any other collateral, and without notice or compliance with any other condition precedent now or hereafter imposed by statute, rule of law or otherwise, all of which are hereby waived, be set off, debited and appropriated, and applied by the Agent or any Lender, as the case may be, against any or all of the Obligations irrespective of whether demand shall have been made and although such Obligations may be unmatured, in such manner as the Agent or the applicable Lender in its sole and absolute discretion may determine. Within five (5) Business Days of making any such set off, debit or appropriation and application, the Agent agrees to notify the Borrower thereof, provided that the failure to give such notice shall not affect the validity of such set off, debit or appropriation and application. ANY AND ALL RIGHTS TO REQUIRE THE AGENT OR ANY LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE LOANS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER, ARE HEREBY KNOWINGLY,

63

VOLUNTARILY AND IRREVOCABLY WAIVED. Each of the Lenders agrees with each other Lender that (a) if an amount to be set off is to be applied to indebtedness of the Borrower to such Lender, other than the obligations evidenced by the Note held by such Lender, such amount shall be applied ratably to such other indebtedness and to the obligations evidenced by the Note held by such Lender, and (b) if such Lender 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 Note held by such Lender 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 held by such Lender any amount in excess of its ratable portion of the payments received by all of the Lenders with respect to the Note held by all of the Lenders, such Lender will make such disposition and arrangements with the other Lenders with respect to such excess, either by way of distribution, pro tanto assignment of claims, subrogation or otherwise as shall result in each Lender receiving in respect of the Note 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 Lender, such disposition and arrangements shall be rescinded and the amount restored to the extent of such recovery, but without interest.

     §15.3 Right to Freeze. The Agent and each of the Lenders shall also have the right, at its option, upon the occurrence of any event which would entitle the Agent or any Lender to set off or debit as set forth in §15.2, to freeze, block or segregate any such deposits, balances and other sums so that the Borrower may not access, control or draw upon the same.

     §15.4 Additional Rights. The rights of the Agent, the Lenders and each affiliate of Administrative Agent and each of the Lenders under this Section 15 are in addition to, and not in limitation of, other rights and remedies, including other rights of set off, which the Agent or any Lender may have.

     §16. THE AGENT.

     §16.1. Authorization. (a) The Agent is authorized to take such action on behalf of each of the Lenders 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. The relationship between the Agent and the Lenders is and shall be that of agent and principal only, and nothing contained in this Agreement or any of the other Loan Documents shall be construed to constitute the Agent as a trustee or fiduciary for any Lender.

          (b) The Borrower, without further inquiry or investigation, shall, and is hereby authorized by the Lenders to, assume that all actions taken by the Agent hereunder and in connection with or under the Loan Documents are duly authorized by the Lenders. The Lenders shall notify Borrower of any successor to Agent by a writing signed by Majority Lenders, which successor shall be reasonably acceptable to the Borrower so long as no Default or Event of Default has occurred and is continuing. The Borrower acknowledges that any Lender which acquires Fleet is acceptable as a successor to the Agent.

     §16.2. Employees and Agents. The Agent may exercise its powers and execute its duties by or through employees or agents and shall be entitled to take, and to rely on, advice of counsel

64

concerning all matters pertaining to its rights and duties under this Agreement and the other Loan Documents. The Agent may utilize the services of such Persons as the Agent in its sole discretion may reasonably determine, and all reasonable fees and expenses of any such Persons shall be paid by the Borrower.

     §16.3. 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 may be liable for losses due to its willful misconduct or gross negligence, as finally determined by a court of competent jurisdiction.

     §16.4. No Representations. The Agent shall not be responsible for the execution or validity or enforceability of this Agreement, the Notes or any of the other Loan Documents or for the validity, enforceability or collectibility 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 Trust or the Borrower or any of their respective Subsidiaries, or be bound to ascertain or inquire as to the performance or observance of any of the terms, conditions, covenants or agreements in this Agreement or the other Loan Documents. The Agent shall not be bound to ascertain whether any notice, consent, waiver or request delivered to it by the Borrower or the Trust or any holder of any of the Notes shall have been duly authorized or is true, accurate and complete. The Agent has not made nor does it now make any representations or warranties, express or implied, nor does it assume any liability to the Lenders, with respect to the credit worthiness or financial condition of the Borrower or any of its Subsidiaries or the Trust or any of the Subsidiaries or any tenant under a Lease or any other entity. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender, and based upon such information and documents as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

     §16.5. Payments.

          (a) A payment by the Borrower to the Agent hereunder or any of the other Loan Documents for the account of any Lender shall constitute a payment to such Lender. The Agent agrees to distribute to each Lender such Lender’s pro rata share of payments received by the Agent for the accounts of all the Lenders, as provided herein or in any of the other Loan Documents. All such payments shall be made on the date received, if before 1:00 p.m., and if after 1:00 p.m., on the next Business Day. If payment is not made on the day received, the funds shall be invested by the Agent in overnight obligations, and interest thereon paid pro rata to the Lenders.

          (b) If in the reasonable 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 material liability, it may refrain from making distribution until its right to make distribution shall have been adjudicated by a court of competent jurisdiction, provided that the Agent shall invest any such undistributed amounts in overnight obligations on behalf of the Lenders and interest thereon shall be paid pro rata to the Lenders. If a court of competent jurisdiction shall adjudge that any amount received and distributed by the Agent is to

65

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 Lender that fails (i) to make available to the Agent its pro rata share of any Loan or to purchase any Letter of Credit Participation or (ii) to adjust promptly such Lender’s outstanding principal and its pro rata Commitment Percentage as provided in §2.1, shall be deemed delinquent (a “Delinquent Lender”) and shall be deemed a Delinquent Lender until such time as such delinquency is satisfied. A Delinquent Lender 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 Lenders for application to, and reduction of, their respective pro rata            shares of all outstanding Loans. The Delinquent Lender hereby authorizes the Agent to distribute such payments to the nondelinquent Lenders in proportion to their respective pro rata            shares of all outstanding Loans. If not previously satisfied directly by the Delinquent Lender, a Delinquent Lender 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 Lenders, the Lenders’ 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.

     §16.6. Holders of Notes. The Agent may deem and treat the payee of any Notes or the Purchaser of any Letter of Credit Participation 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.

     §16.7. Indemnity. The Lenders ratably and severally agree hereby to indemnify and hold harmless the Agent and its Affiliates 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 §17), 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, as finally determined by a court of competent jurisdiction.

     §16.8. Agent as Lender. In its individual capacity as a Lender, KeyBank 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 and as the purchaser of any Letter of Credit Participation, as it would have were it not also the Agent.

     §16.9. Notification of Defaults and Events of Default. Each Lender hereby agrees that, upon learning of the existence of a Default or an Event of Default, it shall (to the extent notice has not previously been provided) promptly notify the Agent thereof. The Agent hereby agrees that upon receipt of any notice under this §16.9 it shall promptly notify the other Lenders of the existence of such Default or Event of Default.

     §16.10. Duties in Case of Enforcement. In the case one or more Events of Default have occurred and shall be continuing, and whether or not acceleration of the Obligations shall have

66

occurred, the Agent shall, at the request, or may, upon the consent, of the Majority Lenders, and provided that the Lenders have given to the Agent such additional indemnities and assurances against expenses and liabilities as the Agent may reasonably request, proceed to enforce the provisions of this Loan Agreement and the other Loan Documents and the exercise of any other legal or equitable rights or remedies as it may have hereunder or under any other Loan Document or otherwise by virtue of applicable law, or to refrain from so acting if similarly requested by the Majority Lenders. The Agent shall be fully protected in so acting or refraining from acting upon the instruction of the Majority Lenders, and such instruction shall be binding upon all the Lenders. The Majority Lenders may direct the Agent in writing as to the method and the extent of any such foreclosure, sale or other disposition or the exercise of any other right or remedy, the Lenders hereby agreeing to severally indemnify and hold the Agent harmless from all costs and liabilities incurred in respect of all actions taken or omitted in accordance with such direction, 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, in its discretion but without obligation, in the absence of direction from the Majority Lenders, take such interim actions as it believes reasonably necessary to preserve the rights of the Lenders hereunder, including but not limited to petitioning a court for injunctive relief or appointment of a receiver. Each of the Lenders acknowledges and agrees that no individual Lender may separately enforce or exercise any of the provisions of any of the Loan Documents, including without limitation the Notes, other than through the Agent. The Agent shall advise the Lenders of all such action taken by the Agent.

     §16.11. Successor Agent. KeyBank, or any successor Agent, may resign as Agent at any time by giving at least 30 days prior written notice thereof to the Lenders and to the Borrower. Any such resignation shall be effective upon appointment and acceptance of a successor Agent, as hereinafter provided, and, at the request of the Majority Lenders, the Agent will resign if its Commitment is no longer at least equal to that of the largest Commitment of any Lender, unless such circumstance is a result of the merger or consolidation of any of the other Lenders or a result of events other than the sale by the Agent of any portion of its Commitment. Upon any such resignation, the Majority Lenders shall have the right to appoint a successor Agent, which is a Lender under this Agreement, provided that so long as no Default or Event of Default has occurred and is continuing the Borrower shall have the right to approve any successor Agent, which approval shall not be unreasonably withheld. If, in the case of a resignation by the Agent, no successor Agent shall have been so appointed by the Majority Lenders and approved by the Borrower, and shall have accepted such appointment, within thirty (30) days after the retiring Agent’s giving of notice of resignation, then the retiring Agent may, on behalf of the Lenders, appoint any one of the other Lenders as a successor Agent. The Borrower acknowledges that any Lender which acquires KeyBank is acceptable as a successor Agent. 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 all further duties and obligations as Agent under this Agreement. After any Agent’s resignation hereunder as Agent, the provisions of this §16 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement. The Agent agrees that it shall not assign any of its rights or duties as Agent to any other Person. The Agent may be removed at the direction of the Majority Lenders in the event of a final judicial determination (in which the Agent had an opportunity to be heard) that the Agent had acted in a grossly negligent manner or in willful misconduct.

67

     §16.12. Notices. Any notices or other information required hereunder to be provided to the Agent (with copies to the Agent for each Lender) shall be forwarded by the Agent to each of the Lenders on the same day (if practicable) and, in any case, on the next Business Day following the Agent’s receipt thereof.

     §16.13. Other Agents. The Syndication Agent shall not have any liabilities or obligations hereunder in its capacity as such.

     §17. 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) the reasonable fees, expenses and disbursements of the Agent’s outside 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, (c) the fees, expenses and disbursements of the Agent incurred by the Agent 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 Eligible Unencumbered Properties, and, without double-counting amounts under clause (b) above, the fees and disbursements of the Agent’s counsel in preparing the documentation, (d) all, if any, title insurance premiums, appraisal fees, engineer’s, inspector’s and surveyor’s fees, (e) the fees, costs, expenses and disbursements of the Agent and its Affiliates incurred in connection with the syndication and/or participations of the Loans (whether occurring before or after the closing hereunder), including, without limitation, reasonable legal fees, travel costs, costs of preparing syndication materials and photocopying costs, (f) all reasonable expenses (including reasonable attorneys’ fees and costs, which attorneys may be employees of any Lender or the Agent, and the fees and costs of engineers, appraisers, surveyors, investment bankers, or other experts retained by any Lender or the Agent in connection with any such enforcement proceedings) incurred by any Lender or the Agent in connection with (i) the enforcement of or preservation of rights under any of the Loan Documents against the Borrower or any of its Subsidiaries or the Trust or the administration thereof after the occurrence and during the continuance 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 any Lender’s or the Agent’s relationship with the Borrower or any of its Subsidiaries or the Trust, (g) all reasonable fees, expenses and disbursements of the Agent incurred in connection with UCC searches and filings, UCC terminations or mortgage discharges, and the like, and (h) all costs incurred by the Agent in the future in connection with its inspection of the Eligible Unencumbered Properties (or any proposed Eligible Unencumbered Property) or with the addition of any Eligible Unencumbered Property. The covenants of this §17 shall survive the repayment of the amounts owing under the Notes and this Agreement and the termination of this Agreement and the obligations of the Lenders hereunder.

     §18. INDEMNIFICATION. The Borrower agrees to indemnify and hold harmless the Agent and each of the Lenders and the shareholders, directors, agents, officers, subsidiaries and affiliates of the Agent and each of the Lenders from and against any and all claims, actions and suits, whether groundless or otherwise, and from and against any and all liabilities, losses (including amounts, if any, owing to any Lender pursuant to §§4.4, 4.5, 4.6 and 4.8), settlement payments, obligations, damages and expenses of every nature and character in connection therewith, arising out of this Agreement or any of the other Loan Documents or the transactions

68

contemplated hereby or thereby or which otherwise arise in connection with the financing, including, without limitation, (a) any actual or proposed use by the Borrower or any of its Subsidiaries of the proceeds of any of the Loans, (b) the Borrower or any of its Subsidiaries entering into or performing this Agreement or any of the other Loan Documents, or (c) pursuant to §8.16, in each case including, without limitation, the reasonable fees and disbursements of counsel and allocated costs of internal counsel incurred in connection with any such investigation, litigation or other proceeding, provided, however, that the Borrower shall not be obligated under this §18 to indemnify any Person for liabilities arising from such Person’s own gross negligence, willful misconduct or breach of this Agreement, as finally determined by a court of competent jurisdiction. In litigation, or the preparation therefor, the Borrower shall be entitled to select counsel reasonably acceptable to the Majority Lenders, and the Agent (as approved by the Majority Lenders) shall be entitled to select their own supervisory counsel, and, in addition to the foregoing indemnity, the Borrower agrees to pay promptly the reasonable fees and expenses of each such counsel. Prior to any settlement of any such litigation by the Lenders, the Lenders shall provide the Borrower and the Trust with notice and an opportunity to address any of their concerns with the Lenders, and the Lenders shall not settle any litigation without first obtaining Borrower’s consent thereto, which consent shall not be unreasonably withheld or delayed, provided that such consent shall not be required at any time that an Event of Default has occurred and is continuing. If and to the extent that the obligations of the Borrower under this §18 are unenforceable for any reason, the Borrower hereby agrees to make the maximum contribution to the payment in satisfaction of such obligations which is permissible under applicable law. The provisions of this §18 shall survive the repayment of the amounts owing under the Notes and this Agreement and the termination of this Agreement and the obligations of the Lenders hereunder and shall continue in full force and effect as long as the possibility of any such claim, action, cause of action or suit exists.

     §19. SURVIVAL OF COVENANTS, ETC. All covenants, agreements, representations and warranties made herein, in the Notes, in any of the other Loan Documents or in any documents or other papers delivered by or on behalf of the Borrower or any of its Subsidiaries or the Trust pursuant hereto shall be deemed to have been relied upon by the Lenders and the Agent, notwithstanding any investigation heretofore or hereafter made by any of them, and shall survive the making by the Lenders of any of the Loans and the issuance, extension or renewal of any Letter of Credit, as herein contemplated, and shall continue in full force and effect so long as any Letter of Credit or any amount due under this Agreement or the Notes or any of the other Loan Documents remains outstanding or any Lender has any obligation to make any Loans or purchase Letter of Credit Participations or the Fronting Bank has any obligation to issue, extend or renew Letters of Credit. The indemnification obligations of the Borrower provided herein and in the other Loan Documents shall survive the full repayment of amounts due and the termination of the obligations of the Lenders hereunder and thereunder to the extent provided herein and therein. All statements contained in any certificate or other paper delivered to any Lender or the Agent at any time by or on behalf of the Borrower or any of its Subsidiaries or the Trust pursuant hereto or in connection with the transactions contemplated hereby shall constitute representations and warranties by the Borrower or such Subsidiary or the Trust hereunder.

     §20. ASSIGNMENT; PARTICIPATIONS; ETC.

     §20.1. Conditions to Assignment by Lenders. Except as provided herein, each Lender may assign to one or more Eligible Assignees all or a portion (in a minimum amount of

69

$5,000,000) of its interests, rights and obligations under this Agreement (including all or a portion of its Commitment Percentage and Commitment and the same portion of the Loans at the time owing to it, the Notes held by it and its participating interest in the risk relating to any Letters of Credit); provided that (a) the Agent and, other than during an Event of Default, the Borrower each shall have the right to approve any Eligible Assignee, which approval shall not be unreasonably withheld or delayed, (b) subject to the provisions of §2.7, each Lender shall have at all times an amount of its Commitment of not less than $5,000,000 unless otherwise consented to by the Agent and (c) the parties to such assignment shall execute and deliver to the Agent, for recording in the Register (as hereinafter defined), an assignment and assumption, substantially in the form of Exhibit D hereto (an “Assignment and Assumption”), together with any Notes subject to such assignment. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Assumption, which effective date shall be at least two (2) Business Days after the execution thereof unless otherwise agreed or accepted by the Agent (provided any assignee has assumed the obligation to fund any outstanding Libor Rate Loans), (i) the assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Assumption, have the rights and obligations of a Lender hereunder and thereunder, and (ii) the assigning Lender shall, to the extent provided in such assignment and upon payment to the Agent of the registration fee referred to in §20.3, be released from its obligations under this Agreement. Any such Assignment and Assumption shall run to the benefit of the Borrower and a copy of any such Assignment and Assumption shall be delivered by the Assignor to the Borrower.

     Notwithstanding the provisions of subclause (a) of the preceding paragraph, any Lender may, without the consent of the Borrower, make an assignment otherwise permitted hereunder to (x) another Lender, and (y) an Affiliate of such Lender, provided that such Affiliate is an Eligible Assignee.

     §20.2. Certain Representations and Warranties; Limitations; Covenants. By executing and delivering an Assignment and Assumption, the parties to the assignment thereunder confirm to and agree with each other and the other parties hereto as follows: (a) other than the representation and warranty that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim, the assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, the other Loan Documents or any other instrument or document furnished pursuant hereto; (b) the assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower and its Subsidiaries or the Trust or any other Person primarily or secondarily liable in respect of any of the Obligations, or the performance or observance by the Borrower and its Subsidiaries or the Trust or any other Person primarily or secondarily liable in respect of any of the Obligations of any of their obligations under this Agreement or any of the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto; (c) such assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements referred to in §7.4 and §8.4 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Assumption; (d) such assignee will, independently and without reliance upon the assigning Lender, the Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (e) such assignee represents and

70

warrants that it is an Eligible Assignee; (f) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to the Agent by the terms hereof or thereof, together with such powers as are reasonably incidental thereto; (g) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement are required to be performed by it as a Lender; (h) such assignee represents and warrants that it is legally authorized to enter into such Assignment and Assumption; and (i) such assignee acknowledges that it has made arrangements with the assigning Lender satisfactory to such assignee with respect to its pro rata share of Letter of Credit Fees in respect of outstanding Letters of Credit.

     §20.3. Register. The Agent shall maintain a copy of each Assignment and Assumption 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 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 Borrower, 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 Borrower 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 $2,500 and all legal fees and expenses incurred by the Agent in connection with such assignment.

     §20.4. New Notes. Upon its receipt of an Assignment and Assumption executed by the parties to such assignment, together with each Note subject to such assignment, the Agent shall (a) record the information contained therein in the Register, and (b) give prompt notice thereof to the Borrower and the Lenders (other than the assigning Lender). Unless done simultaneously with the Assignment and Assumption, within two (2) Business Days after receipt of such notice, the Borrower, at its own expense, shall execute and deliver to the Agent, in exchange for each surrendered Revolving Credit Note, a new Revolving Credit Note to the order of such Eligible Assignee in an amount equal to the amount assumed by such Eligible Assignee pursuant to such Assignment and Assumption and, if the assigning Lender has retained some portion of its obligations hereunder, a new Revolving Credit Note and other Note, if applicable, 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 Assumption and shall otherwise be in substantially the form of the assigned Notes. The surrendered Notes shall be canceled and returned to the Borrower.

     §20.5. Participations. Each Lender may sell participations to one or more lending institutions or other entities in all or a portion of such Lender’s rights and obligations under this Agreement and the other Loan Documents; provided that (a) each such participation shall be in an amount of not less than $5,000,000, (b) any such sale or participation shall not affect the rights and duties of the selling Lender hereunder to the Borrower and the Agent and the Lender shall continue to exercise all approvals, disapprovals and other functions of a Lender, (c) the only rights granted to the participant pursuant to such participation arrangements with respect to waivers, amendments or modifications of, or approvals under, the Loan Documents shall be the rights to approve waivers, amendments or modifications that would reduce the principal of or the

71

interest rate on any Loans, extend the term or increase the amount of the Commitment of such Lender as it relates to such participant, reduce the amount of any fees to which such participant is entitled or extend any regularly scheduled payment date for principal or interest, and (d) no participant shall have the right to grant further participations or assign its rights, obligations or interests under such participation to other Persons without the prior written consent of the Agent, which consent shall not be unreasonably withheld.

     §20.6. Pledge by Lender. Notwithstanding any other provision of this Agreement, any Lender at no cost to the Borrower may at any time pledge all or any portion of its interest and rights under this Agreement (including all or any portion of its Notes) to any of the twelve Federal Reserve Banks organized under §4 of the Federal Reserve Act, 12 U.S.C. §341. No such pledge or the enforcement thereof shall release the pledgor Lender from its obligations hereunder or under any of the other Loan Documents.

     §20.7. No Assignment by Borrower. The Borrower shall not assign or transfer any of its rights or obligations under any of the Loan Documents without prior Unanimous Lender Approval.

     §20.8. Disclosure. The Borrower agrees that, in addition to disclosures made in accordance with standard banking practices, any Lender may disclose information obtained by such Lender pursuant to this Agreement to assignees or participants and potential assignees or participants hereunder.

     §20.9. Syndication. The Borrower acknowledges that each of the Agent and the Arranger intends, and shall have the right, by itself or through its Affiliates, to syndicate or enter into co-lending arrangements with respect to the Loans and the Total Commitment pursuant to this §20. The Arranger, in cooperation with the Borrower, will manage all aspects of the syndication, including the selection of co-lenders, the determination of when Arranger will approach potential co-lenders and the final allocations among co-lenders. Each of the Borrower and the Trust agrees to assist Arranger actively in achieving a timely syndication that is reasonably satisfactory to the Arranger, such assistance to include, among other things, (a) direct contact during the syndication between the Borrower’s and the Trust’s senior officers, representatives and advisors, on the one hand, and prospective co-lenders, on the other hand at such times and places as Arranger may reasonably request, (b) providing to Arranger all financial and other information with respect to the Borrower and the Trust and the transactions contemplated hereby that Arranger may reasonably request, including but not limited to financial projections relating to the foregoing, and (c) assistance in the preparation of a confidential information memorandum and other marketing materials to be used in connection with the syndication, and the Borrower and the Trust agree to cooperate with the Agent’s and the Arranger’s and their Affiliate’s syndication and/or co-lending efforts, such cooperation to include, without limitation, the provision of information reasonably requested by potential syndicate members. In addition, the Borrower and the Trust agree that, prior to and during the syndication of the Total Commitment (which for purposes hereof shall be deemed to be completed 90 days after the Closing Date), the Borrower nor the Trust will permit any offering, placement or arrangement of any competing issues of debt securities or commercial bank facilities of the Borrower, the Trust and any of their Subsidiaries, unless approved by the Agent.

     §24. HEADINGS. The captions in this Agreement are for convenience of reference only and shall not define or limit the provisions hereof.

     §25. COUNTERPARTS. This Agreement and any amendment hereof may be executed in several counterparts and by each party on a separate counterpart, each of which when so executed and delivered shall be an original, and all of which together shall constitute one instrument. In proving this Agreement it shall not be necessary to produce or account for more than one such counterpart signed by the party against whom enforcement is sought.

     §26. ENTIRE AGREEMENT, ETC. The Loan Documents and any other documents executed in connection herewith or therewith express the entire understanding of the parties with respect to the transactions contemplated hereby.

     §27. WAIVER OF JURY TRIAL AND CERTAIN DAMAGE CLAIMS. EXCEPT TO THE EXTENT EXPRESSLY PROHIBITED BY LAW, THE BORROWER AND ITS SUBSIDIARIES HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, THE NOTES OR ANY OF THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER OR THE PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS.

C. 93A ET SEQ. EACH OF THE BORROWER AND ITS SUBSIDIARIES (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY LENDER OR THE AGENT HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH LENDER OR THE AGENT WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS AND (B) ACKNOWLEDGES THAT THE AGENT AND THE LENDERS HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS TO WHICH THEY ARE PARTIES BY, AMONG OTHER THINGS, THE WAIVERS AND CERTIFICATIONS CONTAINED HEREIN.

     §28. CONSENTS, AMENDMENTS, WAIVERS, ETC. Except as otherwise expressly provided in this Agreement, any consent or approval required or permitted by this Agreement may be given, and any term of this Agreement or of any of the other Loan Documents may be

74

amended, and the performance or observance by the Borrower or the Trust or any of their respective Subsidiaries of any terms of this Agreement or the other Loan Documents or the continuance of any Default or Event of Default may be waived (either generally or in a particular instance and either retroactively or prospectively) with, but only with, the written consent of the Majority Lenders.

     Notwithstanding the foregoing, Unanimous Lender Approval shall be required for any amendment, modification or waiver of this Agreement that:

     (i) reduces or forgives any principal of any unpaid Loan or any interest thereon (including any general waiver of interest “breakage” costs) or any fees due any Lender hereunder, or permits any prepayment not otherwise permitted hereunder; or

     (ii) changes the unpaid principal amount of any Loan, reduces the rate of interest applicable to any Loan, or reduces any fee payable to the Lenders hereunder; or

     (iii) changes the date fixed for any payment of principal of or interest on any Loan (including, without limitation, any extension of the Maturity Date not contemplated herein) or any fees payable hereunder (including, without limitation, the waiver of any monetary Event of Default); or

     (iv) changes the amount of any Lender’s Commitment (other than pursuant to an assignment permitted under §20.1) or increases the amount of the Total Commitment except as permitted hereunder; or

     (v) modifies any provision herein or in any other Loan Document which by the terms thereof expressly requires Unanimous Lender Approval; or

     (vi) changes the definitions of Majority Lenders or Unanimous Lender Approval.

     No waiver shall extend to or affect any obligation not expressly waived or impair any right consequent thereon. No course of dealing or delay or omission on the part of the Agent or the Lenders or any Lender in exercising any right shall operate as a waiver thereof or otherwise be prejudicial to such right or any other rights of the Agent or the Lenders. No notice to or demand upon the Borrower shall entitle the Borrower to other or further notice or demand in similar or other circumstances.

     Notwithstanding the foregoing, in the event that the Borrower requests any consent, waiver or approval under this Agreement or any other Loan Document, or an amendment or modification hereof or thereof, and one or more Lenders determine not to consent or agree to such consent, waiver, approval, amendment or modification, then the Lender then acting as Agent hereunder shall have the right to purchase the Commitment of such non-consenting Lender(s)

75

at a purchase price equal to the then outstanding amount of principal, interest and fees then owing to such Lender(s) by the Borrower hereunder, and such non-consenting Lender(s) shall immediately upon request, sell and assign its Commitment and all of its other right, title and interest in the Loans and other Obligations to the Lender then acting as Agent pursuant to an Assignment and Assumption (provided that the selling Lender(s) shall not be responsible to pay any assignment fee in connection therewith).

     §29. SEVERABILITY. The provisions of this Agreement are severable, and if any one clause or provision hereof shall be held invalid or unenforceable in whole or in part in any jurisdiction, then such invalidity or unenforceability shall affect only such clause or provision, or part thereof, in such jurisdiction, and shall not in any manner affect such clause or provision in any other jurisdiction, or any other clause or provision of this Agreement in any jurisdiction.

     §30. INTEREST RATE LIMITATION. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively, the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this §30 shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Rate to the date of repayment, shall have been received by such Lender.
