Not later than 1:00 p.m., Cleveland time, on the date specified for any Loan (which must be a Banking Day), each Bank shall make its Percentage of the Loan in immediately available funds available to the Administrative Agent at the Administrative Agent’s Office.

          (e) Unless the Requisite Banks otherwise consent, each Alternate Base Rate Loan shall be not less than $1,000,000, each LIBOR Rate Loan shall be not less than $1,000,000 and all Loans shall be in an integral multiple of $250,000.

          (f) The Advances made by each Bank under its Commitment shall be evidenced by that Bank’s Line Note.

          (g) A Request for Loan shall be irrevocable upon the Administrative Agent’s first notification thereof.

          (h) If no Request for Loan has been made within the requisite notice periods set forth in Section 2.2 or 2.3 prior to the end of the LIBOR Period for any LIBOR Rate Loan, then on the last day of such LIBOR Period, such LIBOR Rate Loan shall be automatically converted into an Alternate Base Rate Loan in the same amount.

- 24 -

     2.2 Alternate Base Rate Loans. Each request by Borrower for an Alternate Base Rate Loan shall be made pursuant to a Request for Loan received by the Administrative Agent, at the Administrative Agent’s Office, not later than 1:00 p.m., Cleveland time, on the Banking Day immediately prior to the date of the requested Alternate Base Rate Loan.

     2.5 Swing Loan Commitments.

          (a) Subject to the terms and conditions set forth in this Agreement, Swing Loan Bank agrees to lend to Borrower (the “Swing Loans”), and Borrower may borrow (and repay and reborrow) from time to time between the Closing Date and the date which is thirty (30) Banking Days prior to the Maturity Date upon notice by Borrower to the Swing Loan Bank given in accordance with this Section 2.5 such sums as are requested by Borrower for the purposes set forth in Section 5.9 that do not result in (i) an aggregate principal amount of Swing Loans at any one time outstanding (after giving effect to all amounts requested thereunder) being in excess of the Swing Loan Commitment, or (ii) the Outstanding Facility Amount (after giving effect to all amounts requested thereunder) being in excess of the Facility Availability Amount. Swing Loans shall constitute “Line Loans” for all purposes hereunder, but shall not be considered the utilization of a Bank’s Percentage of the Aggregate Commitment. The funding of a Swing Loan hereunder shall constitute a representation and warranty by Borrower that all of the conditions set forth in Article 8 have been satisfied on the date of such funding (other than advance notice requirements).

          (b) The Swing Loans shall be evidenced by a separate promissory note of Borrower in substantially the form of Exhibit F hereto (the “Swing Loan Note”), dated the date of this Agreement and completed with appropriate insertions. The Swing Loan Note shall be payable

- 25 -

to the order of the Swing Loan Bank in such amount as may be outstanding from time to time thereunder and shall be payable as set forth below. The Borrower irrevocably authorizes the Swing Loan Bank to make or cause to be made, at or about the time of the date of any Swing Loan or at the time of receipt of any payment of principal thereof, an appropriate notation on the Swing Loan Bank’s record reflecting the making of such Swing Loan or (as the case may be) the receipt of such payment. The outstanding amount of the Swing Loans set forth on the Swing Loan Bank’s record shall be prima facie evidence of the principal amount thereof owing and unpaid to the Swing Loan Bank, but the failure to record, or any error in so recording, any such amount on the Swing Loan Bank’s record shall not limit or otherwise affect the obligations of Borrower hereunder or under the Swing Loan Note to make payments of principal of or interest on any Swing Loan Note when due.

          (c) Each borrowing of a Swing Loan shall be subject to the limits for Alternate Base Rate Loans set forth in this Agreement. The Borrower shall request a Swing Loan by delivering to the Swing Loan Bank a Request for Loan no later than 2:00 p.m. (Cleveland time) on the requested date specifying the amount of the requested Swing Loan. Each such Request for Loan shall be irrevocable and binding on Borrower and shall obligate Borrower to accept such Swing Loan on the requested date. Notwithstanding anything herein to the contrary, a Swing Loan shall be an Alternate Base Rate Loan that shall bear interest at the Alternate Base Rate. The proceeds of the Swing Loan will be made available by the Swing Loan Bank to Borrower at the Administrative Agent’s Office (on the same Banking Day that the Request for Loan was received, if received prior to the deadline stated above on such day) by crediting the account of Borrower at such office with such proceeds.

          (d) The Swing Loan Bank shall within five (5) Banking Days after the date a Swing Loan is made, request each Bank, including the Swing Loan Bank, to make a Line Loan pursuant to Section 2.1(a) in an amount equal to such Bank’s Percentage of the amount of the Swing Loan outstanding on the date such notice is given. The Borrower hereby irrevocably authorizes and directs the Swing Loan Bank to so act on its behalf, and agrees that any amount advanced to the Administrative Agent for the benefit of the Swing Loan Bank pursuant to this Section 2.5(d) shall be considered a Line Loan pursuant to Section 2.1(a). Unless any of the events described in Section 9.1(j) shall have occurred (in which event the procedures of Section 2.5(e) shall apply), each Bank shall make the proceeds of its Line Loan available to the Swing Loan Bank for the account of the Swing Loan Bank at the Administrative Agent’s Office prior to 1:00 p.m. (Cleveland time) in funds immediately available no later than the next Banking Day after the date such notice is given just as if the Banks were funding an Alternate Base Rate Loan directly to Borrower, so that thereafter such Obligations shall be evidenced by the Line Notes. The proceeds of such Line Loan shall be immediately applied to repay the Swing Loans.

          (e) If prior to the making of a Line Loan pursuant to Section 2.5(d) by all of the Banks, one of the events described in Section 9.1(j) shall have occurred, each Bank will, on the date such Line Loan pursuant to Section 2.5(d) was to have been made, purchase an undivided participating interest in the Swing Loan in an amount equal to its Percentage of such Swing Loan. Each Bank will immediately transfer to the Swing Loan Bank in immediately available funds the amount of its participation and upon receipt thereof the Swing Loan Bank will deliver to such Bank a Swing Loan participation certificate dated the date of receipt of such funds and in such amount.

          (f) Whenever at any time after the Swing Loan Bank has received from any Bank such Bank’s participating interest in a Swing Loan, the Swing Loan Bank receives any

- 26 -

payment on account thereof, the Swing Loan Bank will distribute to such Bank its participating interest in such amount (appropriately adjusted in the case of interest payments to reflect the period of time during which such Bank’s participating interest was outstanding and funded); provided, however, that in the event that such payment received by the Swing Loan Bank is required to be returned, such Bank will return to the Swing Loan Bank any portion thereof previously distributed by the Swing Loan Bank to it.

          (g) Each Bank’s obligation to fund a Line Loan as provided in Section 2.5(d) or to purchase participating interests pursuant to Section 2.5(e) shall be absolute and unconditional and shall not be affected by any circumstance (except only the failure of the Swing Loan Bank to make the request described in Section 2.5(d)), including, without limitation, (i) any setoff, counterclaim, recoupment, defense or other right which such Bank or Borrower may have against the Swing Loan Bank, Borrower or anyone else for any reason whatsoever; (ii) the occurrence or continuance of a Default or an Event of Default; (iii) any adverse change in the condition (financial or otherwise) of Borrower or any other member of the Consolidated Group; (iv) any breach of this Agreement or any of the other Loan Documents by any Bank; (v) the failure to satisfy all of the conditions to disbursement set forth in Article 8; or (vi) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. No such funding or purchase by a Bank under the preceding sentence shall be deemed to be a waiver of any claim that a Bank may otherwise have against the Administrative Agent pursuant to the terms of this Agreement. The provisions of Section 2.9 shall apply to any Bank which fails or refuses to make a Line Loan or fund its participation as provided herein. Each Swing Loan, once so converted, shall cease to be a Swing Loan for the purposes of this Agreement, but shall be a Line Loan made by each Bank under its Commitment.

     2.6 Letters of Credit.

          (a) 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 thirty (30) Banking Days prior to the Maturity Date, the Administrative Agent (including any successor Administrative Agent that takes over such position from KeyBank) shall issue such Letters of Credit as Borrower may request, for the purposes provided in Section 5.9, upon the delivery of a written request in the form of Exhibit G hereto (a “Letter of Credit Request”) to the Administrative Agent, provided that (i) upon issuance of such Letter of Credit, the Letter of Credit Exposure shall not exceed $50,000,000, (ii) the Outstanding Facility Amount (after giving effect to all letters of credit requested thereunder) shall not exceed the Facility Availability Amount, (iii) the conditions set forth in Article 8 shall have been satisfied, and (iv) in no event shall any amount drawn under a Letter of Credit be available for reinstatement or a subsequent drawing under such Letter of Credit. Unless the Administrative Agent otherwise consents, the term of any Letter of Credit shall not exceed the lesser of twelve (12) months or a period of time commencing on the issuance of the Letter of Credit and ending on the Banking Day which is immediately prior to the Maturity Date, provided that any such Letter of Credit may contain an automatic extension or renewal clause, so long as the final expiration date of such Letter of Credit shall not be later than the Banking Day immediately preceding 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 Commitments as a Loan.

- 27 -

          (b) Each Letter of Credit Request shall be submitted to the Administrative Agent at least three (3) Banking Days prior to the date upon which the requested Letter of Credit is to be issued. Each such Letter of Credit Request shall contain (i) a statement as to the purpose for which such Letter of Credit shall be used (which purpose shall be in accordance with the terms of Section 5.9), and (ii) a certification by a Responsible Official of Borrower that 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. Borrower shall further deliver to the Administrative Agent such additional applications and documents as the Administrative Agent may require, in conformity with the then standard practices of its letter of credit department in connection with the issuance of such Letter of Credit; provided that in the event of any conflict, the terms of this Agreement shall control.

          (c) The Administrative Agent shall, if it approves of the content of the Letter of Credit Request (which approval shall not be unreasonably withheld, conditioned or delayed), and subject to the conditions set forth in this Agreement, issue the Letter of Credit. Each Letter of Credit shall be in form and substance satisfactory to the Administrative Agent in its reasonable discretion. Upon issuance of a Letter of Credit, the Administrative Agent shall promptly notify the Banks of such issuance and shall provide copies of each Letter of Credit Request and the corresponding Letter of Credit to any Bank which requests same.

          (d) Upon the issuance of a Letter of Credit, each Bank shall be deemed to have purchased a participation therein from the Administrative Agent in an amount equal to its respective Percentage of the amount of such Letter of Credit, provided that no Bank shall be obligated to transfer funds in such amount to the Administrative Agent at such time.

          (e) Upon the issuance of each Letter of Credit, Borrower shall pay to the Administrative Agent (i) for its own account, an issuance fee equal to the greater of (A) $1,500 or (B) one eighth of one percent (0.125%) per annum to be calculated on the face amount of each Letter of Credit for the stated duration thereof, based on the actual number of days and using a 360-day year basis, payable by Borrower on the issuance of each such Letter of Credit and on the date of any increase therein or extension thereof, plus all reasonable out of pocket costs and the Administrative Agent’s standard charges of issuing, amending and servicing such Letter of Credit and processing draws thereunder, and (ii) for the accounts of the Banks in accordance with their Percentages in such Letter of Credit, a “Letter of Credit Fee” calculated at the rate of the Applicable Margin per annum in effect from time to time with respect to LIBOR Rate Loans on the face amount of such Letter of Credit during the period from and including the issuance date of such Letter of Credit to its expiration or termination date. The Letter of Credit Fee payable to the Banks shall be computed on the basis of a year of 360 days and shall be payable quarterly in arrears as of the first day of each calendar quarter (commencing with the first calendar quarter following the date of issuance of the Letter of Credit) and on the Maturity Date.

          (f) If and to the extent that any amounts are drawn upon any Letter of Credit, the amounts so drawn shall, from the date of payment thereof by the Administrative Agent to either the date of reimbursement thereof by Borrower or repayment through a borrowing by Borrower of a Line Loan, bear interest at the Alternate Base Rate. Upon the receipt by the Administrative Agent of any draw or other presentation for payment of a Letter of Credit and the payment by the Administrative Agent of any amount under a Letter of Credit which is not reimbursed by Borrower within twenty four (24) hours of receipt of notice from the Administrative Agent of such draw, the Administrative Agent shall, without further notice to or the consent of Borrower, direct the Banks to

- 28 -

fund to the Administrative Agent in accordance with Section 2.9 on or before 1:00 p.m. (Cleveland time) on the next Banking Day following Borrower’s failure to reimburse the Administrative Agent, their respective Percentage of the amount so paid by the Administrative Agent as a Line Loan. The proceeds of such funding shall be paid to the Administrative Agent to reimburse the Administrative Agent for the payment made by it under the Letter of Credit and shall thereafter be evidenced by the Line Notes. The provisions of Section 2.9 shall apply to any Bank or Banks failing or refusing to fund its Percentage of any such draw. The Banks shall be required to make such Line Loans regardless of whether all of the conditions to disbursement set forth in Article 8 have been satisfied, provided that the making of such Line Loans shall not be deemed to be a waiver of any claim that a Bank may otherwise have against the Administrative Agent pursuant to this Agreement.

          (g) If, following a draw under any Letter of Credit, but prior to the making of a Line Loan with respect thereto under Section 2.6(f) above, one of the events described in Section 9.1(j) shall have occurred, each Bank will promptly pay to the Administrative Agent in immediately available funds its Percentage of the amount drawn under such Letter of Credit, and upon receipt thereof the Administrative Agent will deliver to such Bank a Letter of Credit participation certificate dated the date of receipt of such funds and in such amount funded by such Bank. The provisions of Section 2.9 shall apply to any Bank which fails or refuses to fund its participation as provided herein.

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

          (i) Unless otherwise approved by the Administrative Agent, each Letter of Credit shall be in an amount of not less than $100,000.

          (j) 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.

          (k) The obligations of Borrower to the Banks and the Administrative Agent to reimburse drawings under Letters of Credit under this Agreement shall be absolute, unconditional and irrevocable, and shall be paid and performed strictly in accordance with the terms of this Agreement, under all circumstances whatsoever and irrespective of any setoff, counterclaim or defense to payment which Borrower may have or have had against the Administrative Agent or any of the Banks (except such as may arise out of the Administrative Agent’s or any Bank’s gross negligence or willful misconduct), including, without limitation, any setoff, counterclaim or defense based upon or arising out of the following circumstances: (i) any improper use which may be made of any Letter of Credit or any improper acts or omissions of any beneficiary or transferee of any Letter of Credit in connection therewith; (ii) the existence of any claim, set off, defense or any right which Borrower may have at any time against any beneficiary or any transferee of any Letter of Credit (or persons or entities for whom any such beneficiary or any such transferee may be acting) or the Banks (other than the defense of payment to the Banks in accordance with the terms of this

- 29 -

Agreement) or any other person, whether in connection with any Letter of Credit, this Agreement, any other Loan Document, or any unrelated transaction; (iii) any statement or any other documents presented under any Letter of Credit proving to be insufficient, forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; (iv) any breach of any agreement between any Borrower and any beneficiary or transferee of any Letter of Credit; (v) any irregularity in the transaction with respect to which any Letter of Credit is issued, including any fraud by the beneficiary or any transferee of such Letter of Credit; and (vi) payment by the Administrative Agent under any Letter of Credit against presentation of a sight draft or a certificate which does not comply with the terms of such Letter of Credit, provided that such payment shall not have constituted gross negligence or willful misconduct on the part of the Administrative Agent.

     2.7 Voluntary Reduction of Aggregate Commitment. Borrower shall have the right, at any time and from time to time, without penalty or charge, upon at least three (3) Banking Days’ prior written notice by a Responsible Official of Borrower to the Administrative Agent, voluntarily to reduce, permanently and irrevocably, in aggregate principal amounts in an integral multiples of $1,000,000 but not less than $5,000,000, or to terminate, all or a portion of the then undisbursed portion of the Aggregate Commitment; provided that in no event shall the Aggregate Commitment be reduced to an amount less than $100,000,000 (unless terminated in its entirety). The Administrative Agent shall promptly notify the Banks of any reduction or termination of the Aggregate Commitment under this Section. Any reduction of the Aggregate Commitment shall be allocated pro rata among the Banks. Upon any such reduction of the Aggregate Commitment, the Swing Loan Bank and the Administrative Agent may each elect, at its option, to reduce the Swing Loan Commitment or the maximum amount of Letter of Credit Exposure pursuant to Section 2.6(a), as the case may be, by the same percentage as the percentage reduction in the Aggregate Commitment.

     2.8 Increase in Aggregate Commitment. At any time after the Closing Date of this Agreement, the Administrative Agent may in its discretion (which discretion shall not be arbitrarily or unreasonably exercised contrary to the request of Borrower so long as the conditions set forth below are satisfied), without the consent of the Banks (except as specified in this Section 2.8), from time to time at the request of Borrower, increase the Aggregate Commitment by (i) admitting additional Banks hereunder (each a “Subsequent Bank”), or (ii) increasing the Commitment of any Bank (each an “Increasing Bank”), subject to the following conditions:

               (i) each Subsequent Bank is an Eligible Assignee;

               (ii) Borrower executes (A) a new Line Note payable to the order of a Subsequent Bank in the amount of its Commitment, or (B) a replacement Line Note payable to the order of an Increasing Bank in the amount of its new, increased Commitment;

               (iii) each Subsequent Bank executes and delivers to the Administrative Agent a signature page to this Agreement, and each Increasing Bank executes and delivers to the Administrative Agent a new signature page to this Agreement reflecting its increased Commitment;

               (iv) after giving effect to the admission of any Subsequent Bank or the increase in the Commitment of any Increasing Bank, the Aggregate Commitment does not exceed $700,000,000;

- 30 -

               (v) no Event of Default exists; and

               (vi) no Bank shall be an Increasing Bank without the written consent of such Bank, which consent such Bank may withhold in its sole and absolute discretion.

After the admission of any Subsequent Bank or increase in the Commitment of any Increasing Bank, the Administrative Agent shall promptly provide to each Bank and to Borrower copies of the signature pages of such Subsequent Bank or Increasing Bank, and a statement of the current Aggregate Commitment and related Percentage of each Bank (which may be in the form of a revised Schedule 1.1).

     2.9  Administrative Agent’s Right to Assume Funds Available for Loans. Unless the Administrative Agent shall have been notified by any Bank no later than 1:00 p.m., Cleveland time on the Banking Day of the proposed funding by the Administrative Agent of any Loan that such Bank does not intend to make available to the Administrative Agent such Bank’s portion of the total amount of such Loan, the Administrative Agent may assume that such Bank has made such amount available to the Administrative Agent on the date of the Loan and the Administrative Agent may, in reliance upon such assumption, make available to Borrower a corresponding amount. If the Administrative Agent has made funds available to Borrower based on such assumption and such corresponding amount is not in fact made available to the Administrative Agent by such Bank, the Administrative Agent shall be entitled to recover such corresponding amount on demand from such Bank plus an administrative fee of $200. If such Bank does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent promptly shall notify Borrower and Borrower shall pay such corresponding amount (but not the administrative fee) to the Administrative Agent. The Administrative Agent also shall be entitled to recover from such Bank or Borrower interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to Borrower to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (i) from such Bank, the daily Federal Funds Effective Rate or (ii) from Borrower, at the applicable rate for such Loan. Nothing herein shall be deemed to relieve any Bank from its obligation to fulfill its Commitment or to prejudice any rights which the Administrative Agent or Borrower may have against any Bank as a result of any default by such Bank hereunder.

     2.10 Extension of Maturity Date. Borrower shall have the one time right and option to extend the Maturity Date with respect to the Facility to June 27, 2010 (which is the first anniversary of the initial Maturity Date), upon satisfaction of the following conditions precedent, which must be satisfied prior to the effectiveness of such extension of the Maturity Date:

            (a) Extension Request. Borrower shall deliver written notice of such request (the “Extension Request”) to the Administrative Agent not earlier than one hundred fifty (150) days and not later than the date which is ninety (90) days prior to the initial Maturity Date.

            (b) Payment of Extension Fee. The Borrower shall pay to the Administrative Agent, at the time of the Extension Request, for the benefit of the Banks an extension fee equal to fifteen one-hundredths of one percent (0.15%) of the then-current Aggregate Commitment.

            (c) No Default. On the date the Extension Request is given and on the initial Maturity Date there shall exist no Event of Default.

          (d) Representations and Warranties. On the date of such Extension Request Borrower shall deliver to the Administrative Agent a Certificate of a Responsible Official signed by a Senior Officer on behalf of Borrower stating that the representations and warranties contained in Article 4 (other than (i) representations and warranties which expressly speak as of a particular date or are no longer true and correct as a result of a change which is not in violation of this Agreement and (ii) as otherwise disclosed by Borrower and approved in writing by the Requisite Banks) will be true and correct in all material respects, both immediately before and after giving effect to the Extension Request, as though such representations and warranties were made on and as of that date.

     2.11 Unencumbered Pool. Borrower may at any time add a Qualified Unencumbered Project to the Unencumbered Pool pursuant to this Section 2.11, which process shall be initiated by delivery by Borrower to the Administrative Agent (which the Administrative Agent shall promptly distribute to the Banks) of a description, in reasonable detail, of the Qualified Unencumbered Project, the most recent year operating income statement related thereto (to the extent available), cash flow projections for such property for the next twelve (12) months, a description of all tenants and leases with respect thereto, a certification of a Senior Officer of Borrower that Borrower has obtained a reasonably current (but in no event older than twelve months) Phase I environmental site assessment prepared by a qualified independent expert with respect to such Qualified Unencumbered Project which provides that there are no recognized environmental conditions thereon that require further action, and other written materials reasonably requested by the Administrative Agent. If any such Project to be added to the Unencumbered Pool hereafter is not wholly-owned in fee simple by Borrower or a Wholly-Owned Subsidiary of Borrower and Borrower is seeking approval for the inclusion of such Project in the Unencumbered Pool as an Exception Project, Borrower must also deliver either the agreement creating the leasehold interest in such Project or the organizational documents for the direct or indirect owners of such Project, together with any related resolutions and consents, as the case may be. The Administrative Agent shall determine, in its reasonable discretion, whether or not such agreement is a Mortgageable Ground Lease or whether or not such organizational documents, resolutions and consents properly authorize the owner of such Project to execute the Joinder Agreement, as the case may be. Notwithstanding the satisfaction of all other criteria specified in this Agreement, no Qualified Unencumbered Project presented by Borrower for inclusion in the Unencumbered Pool shall be deemed added to and to constitute part of the Unencumbered Pool until such time as the Administrative Agent shall have determined that such property meets all the requirements of a Qualified Unencumbered Project under this Agreement (or any such requirements shall have been waived in writing by the Requisite Banks), and the Requisite Banks shall have approved in their reasonable discretion the inclusion of such Qualified Unencumbered Project in the Unencumbered Pool, and the Administrative Agent so notifies Borrower and the Banks in writing. Borrower may remove a property from the Unencumbered Pool by delivery to the Administrative Agent (for distribution to the Banks) of a written notice to that effect, accompanied by a Certificate of a Senior Officer of Borrower setting forth the revised Borrowing Base resulting from such removal, which removal shall be effective on the third (3rd) day after the date of such notice. The Administrative Agent may, upon five (5) Banking Days’ notice to Borrower, remove any Project from the Unencumbered Pool which at any time fails to continue to meet the requirements of a Qualified Unencumbered Project , as specified in this Agreement. Upon the effective date of any such removal under either of the two preceding sentences, the Borrowing Base shall be reduced and Borrower shall make any principal prepayment that may be required under Section 3.1(e) as a result of such reduction in the Borrowing Base. Upon any removal of a Project from the Unencumbered Pool by Borrower or the Administrative Agent pursuant to this Section 2.11, the applicable

- 32 -

Subsidiary Guarantor shall be released from all obligations under the Subsidiary Guaranty and the Administrative Agent shall provide to Borrower, on behalf of itself and the Banks, a written acknowledgement thereof.

ARTICLE 3

     3.1 Principal and Interest.

          (a) Interest shall be payable on the outstanding daily unpaid principal amount of each Advance from the date thereof until payment in full is made and shall accrue and be payable at the rates set forth or provided for herein before and after Default, before and after maturity, before and after judgment, and before and after the commencement of any proceeding under any Debtor Relief Law, with interest on overdue interest at the Default Rate in each case to the fullest extent permitted by applicable Laws. Interest on LIBOR Rate Loans shall be computed on a 360 day year, and actual days elapsed. Interest on Alternate Base Rate Loans shall be computed on a 365 or 366 day year, as applicable, and actual days elapsed.

          (b) Interest accrued on each Alternate Base Rate Loan shall be due and payable on each Monthly Payment Date or at maturity, whether by acceleration or otherwise. Except as otherwise provided in Section 3.6, the unpaid principal amount of any Alternate Base Rate Loan shall bear interest at a fluctuating rate per annum equal to the Alternate Base Rate. Each change in the interest rate under this Section 3.1(b) due to a change in the Alternate Base Rate shall take effect simultaneously with the corresponding change in the Alternate Base Rate.

          (c) Interest accrued on each LIBOR Rate Loan shall be due and payable on each Monthly Payment Date or at maturity, whether by acceleration or otherwise. Except as otherwise provided in Section 3.6, the unpaid principal amount of any LIBOR Rate Loan shall bear interest at a rate per annum equal to the LIBOR Rate for the applicable LIBOR Period.

          (d) In the event that any additional interest becomes due and payable for any period with respect to a Loan as a result of the Applicable Margin being changed due to any change in the Leverage Ratio, and the interest for such period has previously been paid by Borrower, Borrower shall pay to the Administrative Agent for the account of the Banks the amount of such increase within ten (10) days of demand.

          (e) If not sooner paid, the principal Indebtedness evidenced by the Notes shall be payable as follows:

               (i) the amount, if any, by which the principal Indebtedness evidenced by the Notes (after giving effect to all amounts requested thereunder) plus the Letter of Credit Exposure, at any time exceeds the Facility Availability Amount shall be payable immediately upon demand and after the Loans are repaid in full, if any Letter of Credit Exposure is then outstanding, Borrower shall make a deposit to the cash collateral account described in Section 9.2(e) to the extent of the then-current Letter of Credit Exposure; and

               (ii) the principal Indebtedness evidenced by the Notes shall in any event be payable on the Maturity Date applicable thereto.

- 33 -

          (f) The Notes may, at any time and from time to time, voluntarily be paid or prepaid in whole or in part without premium or penalty, except that with respect to any voluntary prepayment under this Section, (i) any partial prepayment shall be not less than $1,000,000, (ii) the Administrative Agent shall have received written notice of any prepayment by noon, Cleveland time on the date of prepayment (which must be a Banking Day) in the case of an Alternate Base Rate Loan, and, in the case of a LIBOR Rate Loan, three (3) Banking Days before the date of prepayment, which notice shall identify the date and amount of the prepayment and the Loan(s) being prepaid, (iii) any payment or prepayment of all or any part of any LIBOR Rate Loan on a day other than the last day of the applicable LIBOR Period shall be subject to Section 3.5(d) and (iv) upon any partial prepayment of a LIBOR Rate Loan that reduces it below $1,000,000, the remaining portion thereof shall automatically convert to an Alternate Base Rate Loan. Notwithstanding the foregoing, no prior notice shall be required for the prepayment of any Swing Loan.

          (g) Unless otherwise approved by the Administrative Agent, Borrower shall cause all gross proceeds of each and every Debt Offering and Equity Offering, less all reasonable costs, fees, expenses, underwriting commissions, fees and discounts incurred in connection therewith, to be paid to the Administrative Agent for the account of the Banks as a prepayment of the Loans within ten (10) days of the date of such offering to the extent of the outstanding balance of the Loans and after the Loans are repaid in full as a deposit to the cash collateral account described in Section 9.2(e) to the extent of the then-current Letter of Credit Exposure. Provided that no Event of Default has occurred and is then continuing, Borrower shall be entitled to designate the Loans to which such required prepayment shall be applied.

     3.2 Other Fees. In addition to the Letter of Credit issuance fee described above, Borrower shall pay to KeyBank each of the other fees specified in the Fee Letter as and when due in accordance therewith.

     3.3 Unused Fees. Borrower agrees to pay to the Administrative Agent for the account of each Bank an unused facility fee (the “Unused Fee”) equal to an aggregate amount computed on a daily basis by multiplying (i) the Unused Fee Percentage applicable to such day, expressed as a per diem rate, times (ii) the excess of the Aggregate Commitment over the Outstanding Facility Amount on such day. The Unused Fee shall be payable quarterly in arrears on the first Banking Day of each calendar quarter (for the prior calendar quarter) and upon any termination of the Aggregate Commitment in its entirety.

     3.4 Increased Commitment Costs. If any Bank shall determine in good faith that the introduction after the Closing Date of any applicable Law or guideline regarding capital adequacy, or any change therein or any change in the interpretation or administration thereof by any central bank or other Governmental Agency charged with the interpretation or administration thereof, or compliance by such Bank (or its LIBOR Lending Office) or any corporation controlling such Bank, with any request, guideline or directive regarding capital adequacy (whether or not having the force of Law) of any such central bank or other authority not imposed as a result of such Bank’s or such corporation’s failure to comply with any other Laws, affects or would affect the amount of capital required or expected to be maintained by such Bank or any corporation controlling such Bank and (taking into consideration such Bank’s or such corporation’s policies with respect to capital adequacy and such Bank’s desired return on capital) determines in good faith that the amount of such capital is increased, or the rate of return on capital is reduced, as a consequence of its

- 34 -

obligations under this Agreement, then, within ten (10) Banking Days after demand of such Bank, Borrower shall pay to such Bank, from time to time as specified in good faith by such Bank, additional amounts sufficient to compensate such Bank in light of such circumstances, to the extent reasonably allocable to such obligations under this Agreement, provided that Borrower shall not be obligated to pay any such amount which arose prior to the date which is one hundred eighty (180) days preceding the date of such demand or is attributable to periods prior to the date which is one hundred eighty (180) days preceding the date of such demand. Each Bank’s determination of such amounts shall be conclusive in the absence of manifest error.

     3.5 LIBOR Costs and Related Matters.

          (a) If, after the date hereof, the existence or occurrence of any Special LIBOR Circumstance:

               (i) shall subject any Bank or its LIBOR Lending Office to any tax, duty or other charge or cost with respect to any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Loans or its obligation to make LIBOR Rate Advances, or shall change the basis of taxation of payments to any Bank attributable to the principal of or interest on any LIBOR Rate Advance or any other amounts due under this Agreement in respect of any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Loans or its obligation to make LIBOR Rate Advances, excluding (i) taxes imposed on or measured in whole or in part by its overall net income (including taxes on gross income imposed in lieu of net income, minimum taxes or branch profits taxes) by (A) any jurisdiction (or political subdivision thereof) in which it is organized or maintains its principal office or LIBOR Lending Office or (B) any jurisdiction (or political subdivision thereof) in which it is “doing business” and (ii) any withholding taxes or other taxes based on gross income imposed by the United States of America for any period with respect to which it has failed, for any reason, to provide Borrower with the appropriate form or forms required by Section 11.21, to the extent such forms are then required by applicable Laws to establish a complete exemption;

               (ii) shall impose, modify or deem applicable any reserve not applicable or deemed applicable on the date hereof (including any reserve imposed by the Board of Governors of the Federal Reserve System, special deposit, capital or similar requirements against assets of, deposits with or for the account of, or credit extended by, any Bank or its LIBOR Lending Office); or

               (iii) shall impose on any Bank or its LIBOR Lending Office or the London interbank market any other condition affecting any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Loans, its obligation to make LIBOR Rate Advances or this Agreement, or shall otherwise affect any of the same;

and the result of any of the foregoing, as determined in good faith by such Bank, increases the cost to such Bank or its LIBOR Lending Office of making or maintaining any LIBOR Rate Advance or in respect of any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Loans or its obligation to make LIBOR Rate Advances or reduces the amount of any sum received or receivable by such Bank or its LIBOR Lending Office with respect to any LIBOR Rate Advance, any of its Notes evidencing LIBOR Rate Loans or its obligation to make LIBOR Rate Advances, then, within five (5) Banking Days after demand by such Bank (with a copy to the Administrative Agent), Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such increased cost or reduction (determined as though such Bank’s LIBOR Lending Office had

- 35 -

funded 100% of its LIBOR Rate Advance in the London interbank market), provided, that with respect to any additional amount arising as a result of the occurrence of an event described in clause (i) above, Borrower shall not be obligated to pay any such amount which arose prior to the date which is ninety (90) days preceding the date of such demand or is attributable to periods prior to the date which is ninety (90) days preceding the date of such demand. A statement of any Bank claiming compensation under this subsection shall be conclusive in the absence of manifest error.

          (b) If, after the date hereof, the existence or occurrence of any Special LIBOR Circumstance shall, in the good faith opinion of any Bank, make it unlawful or impossible for such Bank or its LIBOR Lending Office to make, maintain or fund its portion of any LIBOR Rate Loan, or materially restrict the authority of such Bank to purchase or sell, or to take deposits of, Dollars in the London interbank market, or to determine or charge interest rates based upon the LIBOR Rate, and such Bank shall so notify the Administrative Agent, then such Bank’s obligation to make LIBOR Rate Advances shall be suspended for the duration of such illegality or impossibility and the Administrative Agent forthwith shall give notice thereof to the other Banks and Borrower. Upon receipt of such notice, the outstanding principal amount of such Bank’s LIBOR Rate Advances, together with accrued interest thereon, automatically shall be converted to Alternate Base Rate Advances on either (1) the last day of the LIBOR Period(s) applicable to such LIBOR Rate Advances if such Bank may lawfully continue to maintain and fund such LIBOR Rate Advances to such day(s) or (2) immediately if such Bank may not lawfully continue to fund and maintain such LIBOR Rate Advances to such day(s), provided that in such event the conversion shall not be subject to payment of a prepayment fee under Section 3.5(d). Each Bank agrees to endeavor promptly to notify Borrower of any event of which it has actual knowledge, occurring after the Closing Date, which will cause that Bank to notify the Administrative Agent under this Section, and agrees to designate a different LIBOR Lending Office if such designation will avoid the need for such notice and will not, in the good faith judgment of such Bank, otherwise be materially disadvantageous to such Bank. In the event that any Bank is unable, for the reasons set forth above (or those set forth in clause (d) below), to make, maintain or fund its portion of any LIBOR Rate Loan, such Bank shall fund such amount as an Alternate Base Rate Advance for the same period of time, and such amount shall be treated in all respects as an Alternate Base Rate Advance. Any Bank whose obligation to make LIBOR Rate Advances has been suspended under this Section shall promptly notify the Administrative Agent and Borrower of the cessation of the Special LIBOR Circumstance which gave rise to such suspension.

          (c) If, with respect to any proposed LIBOR Rate Loan:

               (i) the Administrative Agent reasonably determines that, by reason of circumstances affecting the London interbank market generally that are beyond the reasonable control of the Banks, deposits in Dollars (in the applicable amounts) are not being offered to any Bank in the London interbank market for the applicable LIBOR Period; or

               (ii) the Requisite Banks advise the Administrative Agent that the LIBOR Rate as determined by the Administrative Agent (i) does not represent the effective pricing to such Banks for deposits in Dollars in the London interbank market in the relevant amount for the applicable LIBOR Period, or (ii) will not adequately and fairly reflect the cost to such Banks of making the applicable LIBOR Rate Advances;

then the Administrative Agent forthwith shall give notice thereof to Borrower and the Banks, whereupon until the Administrative Agent notifies Borrower that the circumstances giving rise to

- 36 -

such suspension no longer exist, the obligation of the Banks to make any future LIBOR Rate Advances shall be suspended.

          (d) Except for a failure caused by any Bank’s default, Borrower shall indemnify the Banks against any loss or expense that the Banks may sustain or incur (including, without limitation, any loss or expense sustained or incurred in obtaining, liquidating or employing deposits or other funds acquired to effect, fund or maintain any LIBOR Rate Loans) as a consequence of (i) any failure of Borrower to make any payment when due of any amount due hereunder, (ii) any failure of Borrower to borrow, continue or convert a LIBOR Rate Loan on a date specified therefor in a notice thereof, (iii) any failure to fulfill on the scheduled commencement date of any LIBOR Period hereunder the applicable conditions set forth herein as prerequisites to an Advance that is to be a LIBOR Rate Loan or to the election of a LIBOR Rate, (iv) any failure to borrow hereunder after a request for a LIBOR Rate Loan has been given, (v) any payment or prepayment permitted or mandated hereunder of a LIBOR Rate Loan on a date other than the last day of the relevant LIBOR Period, including without limitation upon acceleration following an Event of Default, or (vi) the occurrence of any Event of Default, including but not limited to any loss or expense sustained or incurred or to be sustained or incurred in liquidating or employing deposits from third parties acquired to effect or maintain a LIBOR Rate Loan. Without limiting the foregoing, such loss or expense shall conclusively be deemed to include a “Breakage Fee” (as defined below). The term “Breakage Fee” shall mean that sum equal to the greater of $200 or the financial loss incurred by the Banks resulting from prepayment or failure to borrow, calculated by the Administrative Agent as the difference between the amount of interest the Banks would have earned (from like investments in the Money Markets (as hereinafter defined) as of the first day of the applicable LIBOR Period) had prepayment or failure to borrow not occurred and the interest the Banks would actually earn (from like investments in the Money Markets as of the date of prepayment or failure to borrow) as a result of the redeployment of funds from the prepayment or failure to borrow. Borrower agrees that the Breakage Fee shall not be discounted to its present value. Any voluntary prepayment of a LIBOR Rate Loan shall be in an amount equal to the remaining entire principal balance of such LIBOR Rate Loan. The term “Money Markets” refers to one or more wholesale funding markets available to Banks, including negotiable certificates of deposit, commercial paper, Eurodollar deposits, bank notes, federal funds and others. The Administrative Agent shall provide to Borrower a statement, signed by an officer of the Administrative Agent, explaining any such loss or expense and setting forth the computation of the Breakage Fee pursuant to the preceding provisions which, in the absence of manifest error, shall be conclusive and binding on Borrower.

          (e) Each Bank agrees to endeavor promptly to notify Borrower of any event of which it has actual knowledge, occurring after the Closing Date, which will entitle such Bank to compensation pursuant to this Section 3.5, and agrees to designate a different LIBOR Lending Office if such designation will avoid the need for or reduce the amount of such compensation and will not, in the good faith judgment of such Bank, otherwise be materially disadvantageous to such Bank. Any request for compensation by a Bank under this Section 3.5 shall set forth the basis upon which it has been determined that such an amount is due from Borrower, a calculation of the amount due, and a certification that the corresponding costs have been incurred by the Bank.

     3.6 Late Payments. If any installment of principal or interest or any fee or cost or other amount payable under any Loan Document to the Administrative Agent or any Bank is not paid when due, it shall thereafter bear interest at a fluctuating interest rate per annum (the “Default Rate”) at all times equal to (i) in the case of interest or principal, the sum of the rate otherwise

- 37 -

applicable to the Loans, plus 3% and (ii) in the case of any other amount, the sum of the Alternate Base Rate plus 3%, to the fullest extent permitted by applicable Laws. Accrued and unpaid interest on past due amounts (including, without limitation, interest on past due interest) shall be compounded monthly, on the last day of each calendar month, to the fullest extent permitted by applicable Laws, and shall be payable upon demand. In addition, Borrower shall pay, upon demand, a late charge equal to five percent (5%) of any amount of interest and/or principal payable on the Loans or any other amounts payable hereunder or under the other Loan Documents which is not paid within ten (10) days of the date when due.

     3.7 Computation of Interest and Fees. Computation of interest and fees under this Agreement shall be calculated on the basis of a year of 360 days and the actual number of days elapsed, except that interest at the Alternate Base Rate shall be calculated on the basis of a 365 or 366 day year, as applicable. Interest shall accrue on each Loan for the day on which the Loan is made; interest shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid. Any Loan that is repaid on the same day on which it is made shall bear interest for one day. Notwithstanding anything in this Agreement to the contrary, interest in excess of the maximum amount permitted by applicable Laws shall not accrue or be payable hereunder or under the Notes, and any amount paid as interest hereunder or under the Notes which would otherwise be in excess of such maximum permitted amount shall instead be treated as a payment of principal.

     3.8 Non Banking Days. If any payment to be made by Borrower or any other Party under any Loan Document shall come due on a day other than a Banking Day, payment shall instead be considered due on the next succeeding Banking Day, unless, in the case of a payment relating to a LIBOR Rate Loan, such next succeeding Banking Day is in the next calendar month, in which case such payment shall be made on the next preceding Banking Day, and the extension of time shall be reflected in computing interest and fees.

     3.9 Manner and Treatment of Payments.

          (a) Each payment hereunder (except payments pursuant to Sections 3.4, 3.5, 11.3, 11.11 and 11.22) or on the Notes or under any other Loan Document shall be made to the Administrative Agent at the Administrative Agent’s Office for the account of each of the Banks or the Administrative Agent, as the case may be, in immediately available funds not later than 4:00 p.m., Cleveland time, on the day of payment (which must be a Banking Day). All payments received after such time, on any Banking Day, shall be deemed received on the next succeeding Banking Day. The amount of all payments received by the Administrative Agent for the account of each Bank shall be immediately paid by the Administrative Agent to the applicable Bank in immediately available funds and, if such payment was received by the Administrative Agent by 4:00 p.m., Cleveland time, on a Banking Day and not so made available to the account of a Bank on that Banking Day, the Administrative Agent shall reimburse that Bank for the cost to such Bank of funding the amount of such payment at the Federal Funds Effective Rate. All payments shall be made in Dollars.

          (b) Each payment or prepayment shall be applied first to Swing Loans, then to Alternate Base Rate Loans and finally to LIBOR Rate Loans. Each payment or prepayment on account of any such Alternate Base Rate Loan or LIBOR Rate Loan shall be applied pro rata according to the outstanding Advances made by each Bank comprising such Loan.

- 38 -

          (c) Each Bank shall keep a record (in writing or by an electronic data entry system) of Advances made by it and payments received by it with respect to each of its Notes and, subject to Section 10.6(g), such record shall, as against Borrower, be presumptive evidence of the amounts owing, absent manifest error. Notwithstanding the foregoing sentence, the failure by any Bank to keep such a record shall not affect Borrower’s obligation to pay the Obligations.

          (d) Each payment of any amount payable by Borrower or any other Party under this Agreement or any other Loan Document shall be made without setoff or counterclaim and free and clear of, and without reduction by reason of, any taxes, assessments or other charges imposed by any Governmental Agency, central bank or comparable authority, excluding (i) taxes imposed on or measured in whole or in part by any Bank’s overall net income (including taxes on gross income imposed in lieu of net income tax, minimum taxes or branch profits taxes) by (A) any jurisdiction (or political subdivision thereof) in which such Bank is organized or maintains its principal office or LIBOR Lending Office or (B) any jurisdiction (or political subdivision thereof) in which such Bank is “doing business” and (ii) any withholding taxes or other taxes based on gross income imposed by the United States of America for any period with respect to which any Bank has failed, for whatever reason, timely to provide Borrower with the appropriate form or forms required by Section 11.21, to the extent such forms are then required by applicable Laws to establish a complete exemption (all such non excluded taxes, assessments or other charges being hereinafter referred to as “Taxes”). To the extent that Borrower is obligated by applicable Laws to make any deduction or withholding on account of Taxes from any amount payable to any Bank under this Agreement, Borrower shall (i) make such deduction or withholding and pay the same to the relevant Governmental Agency and (ii) pay such additional amount to that Bank as is necessary to result in that Bank’s receiving a net after Tax amount equal to the amount to which that Bank would have been entitled under this Agreement absent such deduction or withholding.

     3.10 Funding Sources. Nothing in this Agreement shall be deemed to obligate any Bank to obtain the funds for any Loan or Advance in any particular place or manner or to constitute a representation by any Bank that it has obtained or will obtain the funds for any Loan or Advance in any particular place or manner.

     3.11 Failure to Charge Not Subsequent Waiver. Any decision by the Administrative Agent or any Bank not to require payment of any interest (including interest arising under Section 3.6), fee, cost or other amount payable under any Loan Document, or to calculate any amount payable by a particular method, on any occasion shall in no way limit or be deemed a waiver of the Administrative Agent’s or such Bank’s right to require full payment of any interest (including interest arising under Section 3.6), fee, cost or other amount payable under any Loan Document, or to calculate an amount payable by another method that is not inconsistent with this Agreement, on any other or subsequent occasion.

     3.12 Administrative Agent’s Right to Assume Payments Will be Made by Borrower. Unless the Administrative Agent shall have been notified by Borrower prior to the date on which any payment to be made by Borrower hereunder is due that Borrower does not intend to remit such payment, the Administrative Agent may, in its discretion, assume that Borrower has remitted such payment when so due and the Administrative Agent may, in its discretion and in reliance upon such assumption, make available to each Bank on such payment date an amount equal to such Bank’s share of such assumed payment. If Borrower has not in fact remitted such payment to the Administrative Agent, each Bank shall forthwith on demand repay to the Administrative Agent the

- 39 -

amount of such assumed payment made available to such Bank, together with interest thereon in respect of each day from and including the date such amount was made available by the Administrative Agent to such Bank to the date such amount is repaid to the Administrative Agent at the Federal Funds Effective Rate.

     3.13 Calculations Detail. The Administrative Agent, and any Bank, shall provide reasonable detail to Borrower regarding the manner in which the amount of any payment to the Administrative Agent and the Banks, or that Bank, under Article 3 has been determined, within a reasonable period of time after request by Borrower.

     3.14 Survivability. The provisions of Sections 3.4 and 3.5 shall survive following the date on which the Commitments and all Letters of Credit are terminated and all Loans and Obligations with respect to any Letter of Credit hereunder are fully paid, and Borrower shall remain obligated thereunder for all claims under such Sections made by any Bank to Borrower.

ARTICLE 4

REPRESENTATIONS AND WARRANTIES

     Borrower represents and warrants to the Banks that:

     4.1 Existence and Qualification; Power; Compliance With Laws. Parent is a corporation duly formed, validly existing and in good standing under the Laws of Maryland. Borrower is a limited partnership, duly formed, validly existing and in good standing under the Laws of Maryland, and each Guarantor is a corporation, limited partnership, limited liability company or trust duly formed, validly existing and in good standing under the Laws of its state of formation. Each of the Loan Parties is duly qualified or registered to transact business and is in good standing in each other jurisdiction in which the conduct of its business or the ownership or leasing of its Properties makes such qualification or registration necessary, except where the failure so to qualify or register and to be in good standing would not constitute a Material Adverse Effect. Each of the Loan Parties has all requisite power and authority to conduct its business, to own and lease its Properties and to execute and deliver each Loan Document to which it is a Party and to perform its Obligations. All outstanding shares of capital stock of Parent are duly authorized, validly issued, fully paid and nonassessable, and no holder thereof has any enforceable right of rescission under any applicable state or federal securities Laws. To Borrower’s knowledge, each of the Loan Parties is in compliance with all Laws and other legal requirements applicable to its business, has obtained all authorizations, consents, approvals, orders, licenses and permits from, and has accomplished all filings, registrations and qualifications with, or obtained exemptions from any of the foregoing from, any Governmental Agency that are necessary for the transaction of its business, except where the failure so to comply, obtain authorizations, etc., file, register, qualify or obtain exemptions does not constitute a Material Adverse Effect. Parent is a “real estate investment trust” within the meaning of §856 of the Code, has elected to be treated as a real estate investment trust and is subject to federal income taxation as a real estate investment trust pursuant to §§856-860 of the Code.

     4.2 Authority; Compliance With Other Agreements and Instruments and Government Regulations. The execution, delivery and performance by each of the Loan Parties of the Loan Documents to which it is a Party have been duly authorized by all necessary corporate, partnership or limited liability company action, as applicable, and do not and will not:

- 40 -

          (a) Require any consent or approval not heretofore obtained of any partner, director, stockholder, security holder or creditor of the Loan Parties;

          (b) Violate or conflict with any provision of any Loan Party’s charter, articles of incorporation, bylaws or other organizational agreements, as applicable;

          (c) Result in or require the creation or imposition of any Lien upon or with respect to any Property now owned or leased or hereafter acquired by the Loan Parties;

          (d) Violate in any material respect any material Requirement of Law applicable to the Loan Parties; or

          (e) Result in a breach of or constitute a default under, or cause or permit the acceleration of any obligation owed under, any indenture or loan or credit agreement or any other Contractual Obligation to which the Loan Parties are a party or by which the Loan Parties or any of their Property is bound or affected;

and none of the Loan Parties is in violation of, or default under, any Requirement of Law or Contractual Obligation, or any indenture, loan or credit agreement described in Section 4.2(e), in any respect that constitutes a Material Adverse Effect.

     4.3 No Governmental Approvals Required. Except as previously obtained or made, and except for consents, approvals or permits pertaining to construction or development of a type that are routinely granted and that would not normally be obtained before the commencement of performance and which Borrower has no reason to believe will not be obtained as and when required, no authorization, consent, approval, order, license or permit from, or filing, registration or qualification with, any Governmental Agency is or will be required to authorize or permit under applicable Laws the execution, delivery and performance by any of the Loan Parties of the Loan Documents to which it is a Party.

     4.4 Subsidiaries. Schedule 4.4 hereto correctly sets forth the names, form of legal entity, number of shares of capital stock (or other applicable unit of equity interest) issued and outstanding, and the record owner thereof and jurisdictions of organization of all Subsidiaries of Parent. Unless otherwise indicated in Schedule 4.4, all of the outstanding shares of capital stock, or all of the units of equity interest, as the case may be, of each such Subsidiary are owned of record and beneficially by Parent, there are no outstanding options, warrants or other rights to purchase capital stock of any such Subsidiary, and all such shares or equity interests so owned are duly authorized, validly issued, fully paid and nonassessable, and were issued in compliance with all applicable state and federal securities and other Laws, and are free and clear of all Liens, except for Permitted Liens.

     6.17 Limiting Agreements. Enter into any agreement, instrument or transaction (including without limitation any amendment to or modification of the Secured Term Loan Agreement) which has or may have the effect of prohibiting or limiting Borrower’s or any Guarantor’s ability to pledge to the Administrative Agent any Project within the Unencumbered Pool.

               (i) the commitments to make Advances and Swing Loans and to issue Letters of Credit and all other obligations of the Administrative Agent or the Banks and all rights of Borrower and any other Loan Parties under the Loan Documents shall be suspended without notice to or demand upon Borrower, which are expressly waived by Borrower, except that all of the Banks or the Requisite Banks (as the case may be, in accordance with Section 12.1) may waive an Event of Default or, without waiving, determine, upon terms and conditions satisfactory to the Banks or Requisite Banks, as the case may be, to reinstate the Commitments and such other obligations and rights and make further Advances and Swing Loans and to issue Letters of Credit, which waiver or determination shall apply equally to, and shall be binding upon, all the Banks; and

               (ii) the Requisite Banks may request the Administrative Agent to, and the Administrative Agent thereupon shall, terminate the Commitments and/or declare all or any part of the unpaid principal of all Notes, all interest accrued and unpaid thereon and all other amounts payable under the Loan Documents to be forthwith due and payable, whereupon the same shall become and be forthwith due and payable, without protest, presentment, notice of dishonor, demand or further notice of any kind, all of which are expressly waived by Borrower.

          (b) Upon the occurrence and during the continuance of any Event of Default described in Section 9.1(j):

- 61 -

               (i) the commitments to make Advances and Swing Loans and to issue Letters of Credit and all other obligations of the Administrative Agent or the Banks and all rights of Borrower and any other Loan Parties under the Loan Documents shall terminate without notice to or demand upon Borrower, which are expressly waived by Borrower, except that all of the Banks or the Requisite Banks (as the case may be, in accordance with Section 12.1) may waive the Event of Default or, without waiving, determine, upon terms and conditions satisfactory to all the Banks, to reinstate the Commitments and such other obligations and rights and make further Advances and Swing Loans and to issue Letters of Credit, which determination shall apply equally to, and shall be binding upon, all the Banks; and

               (ii) the unpaid principal of all Notes, all interest accrued and unpaid thereon and all other amounts payable under the Loan Documents shall be forthwith due and payable, all without protest, presentment, notice of dishonor, demand or further notice of any kind, all of which are expressly waived by Borrower.

          (c) Upon the occurrence and during the continuance of any Event of Default, the Administrative Agent, on behalf of the Banks, without notice to (except as expressly provided for in any Loan Document) or demand upon Borrower, which are expressly waived by Borrower (except as to notices expressly provided for in any Loan Document), may proceed (but only with the consent of the Requisite Banks) to protect, exercise and enforce their rights and remedies under the Loan Documents against Borrower and any other Loan Party and such other rights and remedies as are provided by Law or equity.

          (d) The order and manner in which the Banks’ rights and remedies are to be exercised shall be determined by the Requisite Banks in their sole discretion, and all payments received by the Administrative Agent and the Banks, or any of them, shall be applied first to the costs and expenses (including reasonable attorneys’ fees and disbursements and the reasonably allocated costs of attorneys employed by the Administrative Agent or by any Bank) of the Administrative Agent and of the Banks, then to the repayment of Swing Loans, and thereafter paid pro rata to the Banks in the same proportions that the aggregate Obligations owed to each Bank under the Loan Documents bear to the aggregate Obligations owed under the Loan Documents to all the Banks, without priority or preference among the Banks. Regardless of how each Bank may treat payments for the purpose of its own accounting, for the purpose of computing the Obligations hereunder and under the Notes, payments shall be applied first, to the costs and expenses of the Administrative Agent and the Banks, as set forth above, second, to the payment of interest and principal (in that order) due on Swing Loans, third, to the payment of accrued and unpaid interest due under any Loan Documents to and including the date of such application (ratably, and without duplication, according to the accrued and unpaid interest due under each of the Loan Documents), and fourth, pari passu to the payment of all other amounts (including principal and fees) then owing to the Administrative Agent or the Banks under the Loan Documents and to the payment of any termination payments due from Borrower in respect of Swap Agreements. No application of payments under this clauses (d) will cure any Event of Default, or prevent acceleration, or continued acceleration, of amounts payable under the Loan Documents, or prevent the exercise, or continued exercise, of rights or remedies of the Banks hereunder or thereunder or at Law or in equity.

          (e) Upon the occurrence, and during the continuance, of any Event of Default, or to the extent required pursuant to Section 3.1 above, Borrower shall at such time deposit in a cash collateral account opened by the Administrative Agent an amount equal to the Letter of Credit

- 62 -

Exposure at such time. Borrower hereby grants to the Administrative Agent, for the benefit of the Banks, a security interest in such cash collateral to secure all obligations of Borrower in respect of such Letters of Credit under this Agreement and the other Loan Documents. Borrower shall execute and deliver to the Administrative Agent, for the account of the Banks, such further documents and instruments as the Administrative Agent may request to evidence the creation and perfection of such security interest in such cash collateral account. Amounts held in such cash collateral account shall be applied by the Administrative Agent to the payment of drafts drawn under such Letters of Credit, and the unused portion thereof after all such Letters of Credit shall have expired or been fully drawn upon, if any, shall be applied to repay other Obligations of Borrower hereunder and under any Notes. After all such Letters of Credit shall have expired or been fully drawn upon, all obligations under the Letters of Credit shall have been satisfied and all other Obligations of Borrower hereunder and under any Notes shall have been paid in full, the balance, if any, in such cash collateral account shall be returned to Borrower. In addition, at any time that amounts are being held in such cash collateral account and the Aggregate Commitment exceeds the Outstanding Facility Amount, the balance in such cash collateral account, to the extent of any such excess of the Aggregate Commitment over the Outstanding Facility Amount, shall be returned to Borrower promptly after the Administrative Agent’s receipt of a written request from Borrower.

ARTICLE 10

THE ADMINISTRATIVE AGENT

     10.1 Appointment and Authorization. Subject to Section 10.8, each Bank hereby irrevocably appoints and authorizes the Administrative Agent to take such action as the contractual representative on its behalf and to exercise such powers under the Loan Documents as are delegated to the Administrative Agent by the terms thereof or are reasonably incidental, as determined by the Administrative Agent, thereto. This appointment and authorization is intended solely for the purpose of facilitating the servicing of the Loans and does not constitute appointment of the Administrative Agent as trustee for any Bank or as representative of any Bank for any other purpose and, the Administrative Agent shall take such action and exercise such powers only in an administrative and ministerial capacity.

     10.2 Administrative Agent and Affiliates. KeyBank (and each successor Administrative Agent in its individual capacity) has the same rights and powers under the Loan Documents as any other Bank and may exercise the same as though it were not the Administrative Agent, and the term “Bank” or “Banks” includes KeyBank in its individual capacity. KeyBank (and each successor Administrative Agent in its individual capacity) and its Affiliates may accept deposits from, lend money to and generally engage in any kind of banking, trust or other business with Borrower or any other member of the Consolidated Group, as if it were not the Administrative Agent and without any duty to account therefor to the Banks. KeyBank (and each successor Administrative Agent in its individual capacity) need not account to any other Bank for any monies received by it for reimbursement of its costs and expenses as the Administrative Agent hereunder, or for any monies received by it in its capacity as a Bank hereunder, other than as required of any Bank hereunder. The Administrative Agent shall not be deemed to hold a fiduciary or agency relationship with any Bank and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or otherwise exist against the Administrative Agent. The provisions of this Section 10.2 shall apply equally to any other agents named herein.

- 63 -

     10.3 Proportionate Interest in any Collateral. The Administrative Agent, on behalf of all the Banks, shall hold in accordance with the Loan Documents all items of collateral (if any) or interests therein received or held by the Administrative Agent. Subject to the Administrative Agent’s and the Banks’ rights to reimbursement for their costs and expenses hereunder (including reasonable attorneys’ fees and disbursements and other professional services and the reasonably allocated costs of attorneys employed by the Administrative Agent or, upon the occurrence and during the continuation of an Event of Default, a Bank) and subject to the application of payments in accordance with Section 9.2(d), each Bank shall have an interest in the Administrative Agent’s interest in such collateral (if any) or interests therein in the same proportions that the aggregate Obligations owed such Bank under the Loan Documents bear to the aggregate Obligations owed under the Loan Documents to all the Banks, without priority or preference among the Banks.

     10.4 Banks’ Credit Decisions. Each Bank agrees that it has, independently and without reliance upon the Administrative Agent, any other Bank or the directors, officers, agents, employees or attorneys of the Administrative Agent or of any other Bank, and instead in reliance upon information supplied to it by or on behalf of Borrower and upon such other information as it has deemed appropriate, made its own independent credit analysis and decision to enter into this Agreement. Each Bank also agrees that it shall, independently and without reliance upon the Administrative Agent, any other Bank or the directors, officers, agents, employees or attorneys of the Administrative Agent or of any other Bank, continue to make its own independent credit analyses and decisions in acting or not acting under the Loan Documents.

     10.5 Action by Administrative Agent.

          (a) Absent actual knowledge of the Administrative Agent of the existence of a Default, the Administrative Agent may assume that no Default (other than the failure to make a payment of principal or interest when due) has occurred and is continuing, unless the Administrative Agent has received notice from Borrower stating the nature of the Default or has received notice from a Bank stating the nature of the Default and that such Bank considers the Default to have occurred and to be continuing.

          (b) The Administrative Agent has only those obligations under the Loan Documents as are expressly set forth therein.

          (c) Except for any obligation expressly set forth in the Loan Documents and as long as the Administrative Agent may assume that no Default has occurred and is continuing, the Administrative Agent may, but shall not be required to, exercise its discretion to act or not act, except that the Administrative Agent shall be required to comply with the instructions of the Requisite Banks (or of all the Banks, to the extent required by Section 12.1) and those instructions shall be binding upon the Administrative Agent and all the Banks, provided that the Administrative Agent shall not be required to comply with such instructions if to do so would be contrary to any Loan Document or to applicable Law or would result, in the reasonable judgment of the Administrative Agent, in substantial risk of liability to the Administrative Agent.

          (d) If the Administrative Agent has received a notice specified in clause (a) or has actual knowledge of the existence of a Default, the Administrative Agent shall promptly give notice thereof to the Banks and shall comply with the instructions of the Requisite Banks (or of all the Banks, to the extent required by Section 12.1), provided that the Administrative Agent shall not be required to comply with such instructions if to do so would be contrary to any Loan Document or

- 64 -

to applicable Law or would result, in the reasonable judgment of the Administrative Agent, in substantial risk of liability to the Administrative Agent, and except that if the Requisite Banks (or all the Banks, if required under Section 12.1) fail, for five (5) Banking Days after the receipt of notice from the Administrative Agent, to instruct the Administrative Agent, then the Administrative Agent, in its sole discretion, may act or not act as it deems advisable for the protection of the interests of the Banks.

     10.6 Liability of Administrative Agent. Neither the Administrative Agent nor any of its directors, officers, agents, employees or attorneys shall be liable for any action taken or not taken by them under or in connection with the Loan Documents, except for their own gross negligence or willful misconduct. Without limitation on the foregoing, the Administrative Agent and its directors, officers, agents, employees and attorneys:

          (a) May treat the payee of any Note as the holder thereof until the Administrative Agent receives notice of the assignment or transfer thereof, in form satisfactory to the Administrative Agent, signed by the payee, and may treat each Bank as the owner of that Bank’s interest in the Obligations for all purposes of this Agreement until the Administrative Agent receives notice of the assignment or transfer thereof, in form satisfactory to the Administrative Agent, signed by that Bank;

          (b) May consult with legal counsel (including in house legal counsel), accountants (including in house accountants) and other professionals or experts selected by it, or with legal counsel, accountants or other professionals or experts for the Consolidated Group or the Banks, and shall not be liable for any action taken or not taken by it in good faith in accordance with any advice of such legal counsel, accountants or other professionals or experts;

          (c) Shall not be responsible to any Bank for any statement, warranty or representation made in any of the Loan Documents or in any notice, certificate, report, request or other statement (written or oral) given or made in connection with any of the Loan Documents;

          (d) Shall have no duty to ask or inquire as to the performance or observance by Borrower or the Loan Parties of any of the terms, conditions (except to ascertain that documents facially responsive to the requirements of Article 8 have been delivered) or covenants of any of the Loan Documents or to inspect any collateral or any Property, books or records of the Loan Parties;

          (e) Will not be responsible to any Bank for the due execution, legality, validity, enforceability, genuineness, effectiveness, sufficiency or value of any Loan Document, any other instrument or writing furnished pursuant thereto or in connection therewith, or any collateral;

          (f) Will not incur any liability by acting or not acting in reliance upon any Loan Document, notice, consent, certificate, statement, request or other instrument or writing believed in good faith by it to be genuine and signed or sent by the proper party or parties;

          (g) Will not incur any liability for any arithmetical error in computing any amount paid or payable by Borrower or any other Loan Party thereof or paid or payable to or received or receivable from any Bank under any Loan Document, including, without limitation, principal, interest, commitment fees, Advances and other amounts; provided that, promptly upon discovery of such an error in computation, the Administrative Agent, the Banks and (to the extent applicable) Borrower and/or the other Loan Parties shall make such adjustments as are necessary to

- 65 -

correct such error and to restore the parties to the position that they would have occupied had the error not occurred; and

          (h) Have not made nor do they now make any representations or warranties, express or implied, nor do they assume any liability to the Banks, with respect to the creditworthiness or financial condition of the Consolidated Group, the value of their respective assets or the collectability of the Loans.

     10.7 Indemnification. Each Bank shall, ratably in accordance with its Percentage of the aggregate Commitments (if the Commitments are then in effect) or in accordance with its proportion of the aggregate Indebtedness then evidenced by the Notes and Letter of Credit Exposure (if the Commitments have then been terminated), indemnify and hold the Administrative Agent and its directors, officers, agents, employees and attorneys harmless against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including reasonable attorneys’ fees and disbursements and allocated costs of attorneys employed by the Administrative Agent) that may be imposed on, incurred by or asserted against it or them in any way relating to or arising out of the Loan Documents (other than losses incurred by reason of the failure of Borrower to pay the Indebtedness represented by the Notes) or any action taken or not taken by it as the Administrative Agent thereunder, except such as result from its own gross negligence or willful misconduct. Without limitation on the foregoing, each Bank shall reimburse the Administrative Agent upon demand for that Bank’s Percentage of any out of pocket cost or expense incurred by the Administrative Agent in connection with the negotiation, preparation, execution, delivery, amendment, waiver, restructuring, reorganization (including a bankruptcy reorganization), enforcement or attempted enforcement of the Loan Documents, to the extent that any Borrower or any other Loan Party is required by Section 11.3 to pay that cost or expense but fails to do so upon demand. Nothing in this Section 10.7 shall entitle the Administrative Agent or any indemnitee referred to above to recover any amount from the Banks if and to the extent that such amount has theretofore been recovered from Borrower or any other Loan Party. To the extent that the Administrative Agent or any indemnitee referred to above is later reimbursed such amount by Borrower or any other Loan Party, it shall return the amounts paid to it by the Banks in respect of such amount.

     10.8 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon reasonable notice to the Banks and Borrower effective not earlier than thirty (30) days after such notice, upon acceptance of appointment by a successor Administrative Agent. The Requisite Banks may (with the prior consent, not to be unreasonably withheld or delayed, of Parent, unless an Event of Default shall have occurred and be continuing) remove the Administrative Agent from its capacity as Administrative Agent in the event of the Administrative Agent’s willful misconduct or gross negligence. If the Administrative Agent shall resign or be removed as Administrative Agent under this Agreement, the Requisite Banks shall appoint from among the Banks a successor Administrative Agent for the Banks, which successor Administrative Agent shall require approval by Parent so long as no Default or Event of Default has occurred and is continuing (and such approval shall not be unreasonably withheld or delayed). If no successor Administrative Agent is appointed prior to the effective date of the resignation of the Administrative Agent, the Administrative Agent may appoint, after consulting with the Banks and, so long as no Default or Event of Default has occurred and is continuing, with the consent of Parent, a successor Administrative Agent from among the Banks. Upon the acceptance of its appointment as successor Administrative Agent hereunder, such successor Administrative Agent shall succeed to

- 66 -

all the rights, powers and duties of the retiring Administrative Agent and the term “Administrative Agent” shall mean such successor Administrative Agent and the retiring Administrative Agent’s appointment, powers and duties as Administrative Agent shall be terminated. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Article 10, and Sections 11.3, 11.11 and 11.22, shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. Notwithstanding the foregoing, if (a) the Administrative Agent has not been paid its administrative agency fees under the Fee Letter or has not been reimbursed for any expense reimbursable to it under Section 11.3, in either case for a period of at least one (1) year and (b) no successor Administrative Agent has accepted appointment as Administrative Agent by the date which is thirty (30) days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Banks shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Requisite Banks appoint a successor Administrative Agent as provided for above.

     10.9 No Obligations of Borrower. Nothing contained in this Article 10 shall be deemed to impose upon Borrower any obligation in respect of the due and punctual performance by the Administrative Agent of its obligations to the Banks under any provision of this Agreement, and Borrower shall have no liability to the Administrative Agent or any of the Banks in respect of any failure by the Administrative Agent or any Bank to perform any of its obligations to the Administrative Agent or the Banks under this Agreement. Without limiting the generality of the foregoing, where any provision of this Agreement relating to the payment of any amounts due and owing under the Loan Documents provides that such payments shall be made by Borrower to the Administrative Agent for the account of the Banks, Borrower’s obligations to the Banks in respect of such payments shall be deemed to be satisfied upon the making of such payments to the Administrative Agent in the manner provided by this Agreement.

     10.10 Agents. Neither the Lead Arranger nor the Syndication Agent as shown on the cover of this Agreement have any additional rights or obligations under the Loan Documents, except for those rights or obligations, if any, as a Bank.

ARTICLE 11

MISCELLANEOUS

     11.1 Cumulative Remedies; No Waiver. The rights, powers, privileges and remedies of the Administrative Agent and the Banks provided herein or in any Note or other Loan Document are cumulative and not exclusive of any right, power, privilege or remedy provided by Law or equity. No failure or delay on the part of the Administrative Agent or any Bank in exercising any right, power, privilege or remedy may be, or may be deemed to be, a waiver thereof; nor may any single or partial exercise of any right, power, privilege or remedy preclude any other or further exercise of the same or any other right, power, privilege or remedy. The terms and conditions of Article 8 hereof are inserted for the sole benefit of the Administrative Agent and the Banks; the same may be waived in whole or in part, with or without terms or conditions, in respect of any Loan without prejudicing the Administrative Agent’s or the Banks’ rights to assert them in whole or in part in respect of any other Loan.

     11.2 [Intentionally Omitted.]

- 67 -

     11.3 Costs, Expenses and Taxes. Borrower shall pay within five (5) Banking Days after demand, accompanied by an invoice therefor, the reasonable costs and expenses of the Administrative Agent in connection with the negotiation, preparation, syndication, execution, delivery, administration and interpretation of the Loan Documents and any amendment thereto or waiver thereof. Following and during the continuation of an Event of Default, Borrower shall also pay on demand, accompanied by an invoice therefor, the reasonable costs and expenses of the Administrative Agent and the Banks in connection with the refinancing, restructuring, reorganization (including a bankruptcy reorganization) and enforcement or attempted enforcement of the Loan Documents, and any matter related thereto. The foregoing costs and expenses shall include filing fees, recording fees, title insurance fees, appraisal fees, search fees, and other out of pocket expenses and the reasonable fees and out of pocket expenses of any legal counsel (including reasonably allocated costs of legal counsel employed by the Administrative Agent or any Bank), independent public accountants and other outside experts retained by the Administrative Agent or any Bank, whether or not such costs and expenses are incurred or suffered by the Administrative Agent or any Bank in connection with or during the course of any bankruptcy or insolvency proceedings of any member of the Consolidated Group. Borrower shall pay any and all documentary and other taxes, excluding (i) taxes imposed on or measured in whole or in part by any Bank’s overall net income imposed on such Bank (including taxes on gross income imposed in lieu of net income, minimum taxes or branch profits taxes) by (A) any jurisdiction (or political subdivision thereof) in which such Bank is organized or maintains its principal office or LIBOR Lending Office or (B) any jurisdiction (or political subdivision thereof) in which such Bank is “doing business” or (ii) any withholding taxes or other taxes based on gross income imposed by the United States of America for any period with respect to which any Bank has failed, for any reason, to provide Borrower with the appropriate form or forms required by Section 11.21, to the extent such forms are then required by applicable Laws to establish a complete exemption, and all costs, expenses, fees and charges payable or determined to be payable in connection with the filing or recording of this Agreement, any other Loan Document or any other instrument or writing to be delivered hereunder or thereunder, or in connection with any transaction pursuant hereto or thereto, and shall reimburse, hold harmless and indemnify on the terms set forth in Section 11.11 the Administrative Agent and the Banks from and against any and all loss, liability or legal or other expense with respect to or resulting from any delay in paying or failure to pay any such tax, cost, expense, fee or charge or that any of them may suffer or incur by reason of the failure of any Party to perform any of its Obligations. Any amount payable to the Administrative Agent or any Bank under this Section 11.3 shall bear interest from the fifth Banking Day following the date of demand for payment at the Default Rate.

     11.4 Nature of Banks’ Obligations. The obligations of the Banks hereunder are several and not joint or joint and several. Nothing contained in this Agreement or any other Loan Document and no action taken by the Administrative Agent or the Banks or any of them pursuant hereto or thereto may, or may be deemed to, make the Banks a partnership, an association, a joint venture or other entity, either among themselves or with Borrower or any other member of the Consolidated Group. A default by any Bank will not increase the Percentage of the Commitments attributable to any other Bank. Any Bank not in default may, if it desires, assume in such proportion as the nondefaulting Banks agree the obligations of any Bank in default, but is not obligated to do so. The Administrative Agent agrees that it will use reasonable efforts (which will not include the payment of money) either to induce the other Banks to assume the obligations of a Bank in default or to obtain another Bank, reasonably satisfactory to Borrower, to replace such a Bank in default. A defaulting Bank’s right to participate in the administration of the Loan

- 68 -

Documents, including, without limitation, any rights to consent to or direct any action or inaction of the Administrative Agent or to vote on any matter presented to the Banks shall be suspended during the pendency of such Bank’s default.

     11.5 Survival of Representations and Warranties. All representations and warranties contained herein or in any other Loan Document, or in any certificate or other writing delivered by or on behalf of any one or more of the Parties to any Loan Document, will survive the making of the Loans hereunder and the execution and delivery of the Notes, and have been or will be relied upon by the Administrative Agent and each Bank, notwithstanding any investigation made by the Administrative Agent or any Bank or on their behalf.

     11.6 Notices. Except as otherwise expressly provided in the Loan Documents, all notices, requests, demands, directions and other communications provided for hereunder or under any other Loan Document must be in writing and must be mailed, telegraphed, telecopied, dispatched by commercial courier or delivered to the appropriate party at the address set forth on the signature pages of this Agreement or other applicable Loan Document or, as to any party to any Loan Document, at any other address as may be designated by it in a written notice sent to all other parties to such Loan Document in accordance with this Section. Except as otherwise expressly provided in any Loan Document, if any notice, request, demand, direction or other communication required or permitted by any Loan Document is given by mail it will be effective on the earlier of receipt or the fourth Banking Day after deposit in the United States mail with first class or airmail postage prepaid; if given by telegraph or cable, when delivered to the telegraph company with charges prepaid; if given by telecopier, when sent; if dispatched by commercial courier, on the scheduled delivery date; or if given by personal delivery, when delivered (provided that if any such communication is received after normal business hours or on a day that is not a Banking Day, it shall be deemed to have been received on the next Banking Day following receipt). The Administrative Agent and the Banks shall be entitled to rely and act upon any notices purportedly given by or on behalf of Borrower and Banks shall be entitled to rely and act upon any notices purportedly given to them by or on behalf of the Administrative Agent, even if (i) such notices were not made in a manner specified herein, were incomplete or were not preceded or followed by any other form of notice specified herein, or (ii) the terms thereof, as understood by the recipient, varied from any confirmation thereof. Borrower shall indemnify the Administrative Agent and each Bank from all losses, costs, expenses and liabilities resulting from the reliance of such Person on each notice purportedly given by Borrower, except to the extent of such Person’s gross negligence.

     11.7 Execution of Loan Documents. Unless the Administrative Agent otherwise specifies with respect to any Loan Document, (a) this Agreement and any other Loan Document may be executed in any number of counterparts and any party hereto or thereto may execute any counterpart, each of which when executed and delivered will be deemed to be an original and all of which counterparts of this Agreement or any other Loan Document, as the case may be, when taken together will be deemed to be but one and the same instrument and (b) execution of any such counterpart may be evidenced by a telecopier transmission of the signature of such party. The execution of this Agreement or any other Loan Document by any party hereto or thereto will not become effective until counterparts hereof or thereof, as the case may be, have been executed by all the parties hereto or thereto.

- 69 -

     11.8 Binding Effect; Assignment.

          (a) This Agreement and the other Loan Documents to which the Loan Parties are a party are and will be binding upon and inure to the benefit of the Loan Parties, the Administrative Agent, each of the Banks, and their respective successors and assigns, except that the Loan Parties may not assign their rights hereunder or thereunder or any interest herein or therein without the prior written consent of all the Banks, and any purported assignment without such consent shall be null and void. Each Bank represents that it is not acquiring its Note with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (subject to any requirement that disposition of such Note must be within the control of such Bank). Any Bank may at any time pledge its Notes or any other instrument evidencing its rights as a Bank under this Agreement to a Federal Reserve Bank, but no such pledge shall release that Bank from its obligations hereunder or grant to such Federal Reserve Bank the rights of a Bank hereunder absent foreclosure of such pledge.

          (b) From time to time following the Closing Date, each Bank may assign to one or more Eligible Assignees all or any portion of its Commitment; provided that (i) such Eligible Assignee, if not then a Bank or an Affiliate of the assigning Bank, shall require approval by the Administrative Agent and (if no Event of Default then exists) Parent (neither of which approvals shall be unreasonably withheld or delayed), (ii) such assignment shall be evidenced by a Commitment Assignment and Acceptance, a copy of which, together with any Notes subject to such assignment, shall be furnished to the Administrative Agent as hereinbelow provided, (iii) except in the case of an assignment to an Affiliate of the assigning Bank, to another Bank or of the entire remaining Commitments of the assigning Bank, the assignment shall not assign a share of the Commitments that is equivalent to less than $10,000,000, (iv) the assignment shall be of a constant, and not a varying, percentage of the Assignor’s rights and obligations under this Agreement, and (v) the effective date of any such assignment shall be as specified in the Commitment Assignment and Acceptance, but not earlier than the date which is five (5) Banking Days after the date the Administrative Agent has received the Commitment Assignment and Acceptance unless otherwise agreed by the Administrative Agent. Upon the effective date of such Commitment Assignment and Acceptance, the Eligible Assignee named therein shall be a Bank for all purposes of this Agreement, with a Percentage and Commitment as therein (and herein, if such Eligible Assignee was already a Bank) set forth and, to the extent of the portion of the Commitments assigned, the assigning Bank shall be released from its further obligations under this Agreement. Borrower agrees that it shall execute and deliver to such assignee Bank, Notes evidencing that assignee Bank’s Commitment, and to the assigning Bank, Notes evidencing the remaining balance of such Bank’s Commitment.

          (c) By executing and delivering a Commitment Assignment and Acceptance, the Eligible Assignee thereunder acknowledges and agrees that: (i) the Administrative Agent has not made any 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 or sufficiency of this Agreement or any other Loan Document; (ii) the Administrative Agent has not made any representation or warranty and assumes no responsibility with respect to the financial condition of the Loan Parties or the performance by the Loan Parties of the Obligations; (iii) it has received a copy of this Agreement, together with copies of the most recent financial statements delivered pursuant to Section 7.1 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Commitment Assignment and Acceptance; (iv) it will, independently and

- 70 -

without reliance upon the Administrative Agent or any Bank 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; (v) it appoints and authorizes the Administrative Agent to take such action and to exercise such powers under this Agreement as are delegated to the Administrative Agent by this Agreement; and (vi) it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Bank.

          (d) The Administrative Agent shall maintain at the Administrative Agent’s Office a copy of each Commitment Assignment and Acceptance delivered to it and a register (the “Register”) of the names and address of each of the Banks and the Percentage and Commitment amounts held by each Bank, giving effect to each Commitment Assignment and Acceptance. The Register shall be available during normal business hours for inspection by Borrower or any Bank upon reasonable prior notice to the Administrative Agent. After receipt of a completed Commitment Assignment and Acceptance executed by any Bank and an Eligible Assignee and the Notes subject to such assignment, and receipt of an assignment fee of $3,500 from such Bank or Eligible Assignee, the Administrative Agent shall, promptly following the effective date thereof, upon the request of any party, provide to Borrower and the Banks a revised Schedule 1.1 giving effect thereto. Borrower, the Administrative Agent and the Banks shall deem and treat the Persons listed as Banks in the Register as the holders and owners of the Commitments listed therein for all purposes hereof, and no assignment or transfer of any such Commitment shall be effective, in each case unless and until a Commitment Assignment and Acceptance effecting the assignment or transfer thereof shall have been accepted by the Administrative Agent and recorded in the Register as provided above. Prior to such recordation, all amounts owed with respect to the applicable Commitments shall be owed to the Bank listed in the Register as the owner thereof, and any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is listed in the Register as a Bank shall be conclusive and binding on any subsequent holder, assignee or transferee of such Commitments.

          (e) Each Bank may from time to time grant participations to one or more banks or other financial institutions (including another Bank but excluding an Employee Plan) in a portion of its Commitments; provided, however, that (i) such Bank’s obligations under this Agreement shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participating banks or other financial institutions shall not be a Bank hereunder for any purpose except, if the participation agreement so provides, for the purposes of Sections 3.7, 3.8, 11.11 and 11.22 but only to the extent that the cost of such benefits to Borrower does not exceed the cost which Borrower would have incurred absent the participation, (iv) Borrower, the Administrative Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this Agreement, (v) the participation interest shall be expressed as a percentage of the granting Bank’s Commitment as they then exist and shall not afford such participant any rights or privileges under the Loan Documents except as provided in clause (iii) above.

     11.9 Right of Setoff. If an Event of Default has occurred and is continuing, the Administrative Agent or any Bank (but in each case only with the consent of the Requisite Banks and subject to the provisions of Section 11.10) may exercise its rights, if any, under Article 9 of the Uniform Commercial Code and other applicable Laws and, to the extent permitted by applicable Laws, apply any funds in any deposit account maintained with it by Borrower and/or any Property

- 71 -

of Borrower in its possession against the Obligations. any and all rights to require administrative agent or any bank to exercise its rights or remedies with respect to any other collateral which secures the loan (if any), prior to exercising its right of setoff with respect to such deposits, credits, or other property of borrowers, are hereby, knowingly, voluntarily, and irrevocably waived.

     11.10 Sharing of Setoffs. Each Bank severally agrees that if it, through the exercise of any right of setoff, banker’s lien or counterclaim against Borrower, or otherwise, receives payment of the Obligations held by it that is ratably more than any other Bank, or through any means, receives in payment of the Obligations held by that Bank, then, subject to applicable Laws: (a) the Bank exercising the right of setoff, banker’s lien or counterclaim or otherwise receiving such payment shall purchase, and shall be deemed to have simultaneously purchased, from each of the other Banks a participation in the Obligations held by the other Banks and shall pay to the other Banks a purchase price in an amount so that the share of the Obligations held by each Bank after the exercise of the right of setoff, banker’s lien or counterclaim or receipt of payment shall be in the same proportion that existed prior to the exercise of the right of setoff, banker’s lien or counterclaim or receipt of payment; and (b) such other adjustments and purchases of participations shall be made from time to time as shall be equitable to ensure that all of the Banks share any payment obtained in respect of the Obligations ratably in accordance with each Bank’s share of the Obligations immediately prior to, and without taking into account, the payment; provided that, if all or any portion of a disproportionate payment obtained as a result of the exercise of the right of setoff, banker’s lien, counterclaim or otherwise is thereafter recovered from the purchasing Bank by Borrower or any Person claiming through or succeeding to the rights of Borrower, the purchase of a participation shall be rescinded and the purchase price thereof shall be restored to the extent of the recovery, but without interest (unless the Bank from which such payment is recovered is required to pay interest thereon, in which case each Bank returning funds to such Bank shall pay its pro rata share of such interest). Each Bank that purchases a participation in the Obligations pursuant to this Section 11.10 shall from and after the purchase have the right to give all notices, requests, demands, directions and other communications under this Agreement with respect to the portion of the Obligations purchased to the same extent as though the purchasing Bank were the original owner of the Obligations purchased. Borrower expressly consents to the foregoing arrangements and agrees that any Bank holding a participation in an Obligation so purchased pursuant to this Section 11.10 may exercise any and all rights of setoff, banker’s lien or counterclaim with respect to the participation as fully as if the Bank were the original owner of the Obligation purchased.

     11.11 Indemnity by Borrower. Borrower agrees to indemnify, save and hold harmless the Administrative Agent and Lead Arranger and each Bank and its Affiliates and their respective directors, officers, agents, attorneys and employees (collectively the “Indemnitees”) from and against: (a) any and all claims, demands, actions or causes of action (except a claim, demand, action, or cause of action for any amount excluded from the definition of “Taxes” in Section 3.9(d)) if the claim, demand, action or cause of action arises out of or relates to any act or omission (or alleged act or omission) of Borrower, the other members of the Consolidated Group or any of their officers, directors or stockholders relating to the Commitments, the use or contemplated use of proceeds of any Loan or any Letter of Credit, or the relationship of Borrower and the Banks under this Agreement; (b) any administrative or investigative proceeding by any Governmental Agency arising out of or related to a claim, demand, action or cause of action described in clause (a) above; and (c) any and all liabilities, losses, costs or expenses (including reasonable attorneys’ fees and the reasonably allocated costs of attorneys employed by any Indemnitee and disbursements of such

- 72 -

attorneys and other professional services) that any Indemnitee suffers or incurs as a result of the assertion of any foregoing claim, demand, action or cause of action; provided that no Indemnitee shall be entitled to indemnification for any loss caused by its own gross negligence or willful misconduct or for any loss asserted against it by another Indemnitee. If any claim, demand, action or cause of action is asserted against any Indemnitee, such Indemnitee shall promptly notify Borrower, but the failure to so promptly notify Borrower shall not affect Borrower’s obligations under this Section unless such failure materially prejudices Borrower’s right to participate in the contest of such claim, demand, action or cause of action, as hereinafter provided. Such Indemnitee may (and shall, if requested by Borrower in writing) contest the validity, applicability and amount of such claim, demand, action or cause of action and shall permit Borrower to participate in such contest. Any Indemnitee that proposes to settle or compromise any claim or proceeding for which Borrower may be liable for payment of indemnity hereunder shall give Borrower written notice of the terms of such proposed settlement or compromise reasonably in advance of settling or compromising such claim or proceeding and shall obtain Borrower’s prior written consent (which shall not be unreasonably withheld or delayed). In connection with any claim, demand, action or cause of action covered by this Section 11.11 against more than one Indemnitee, all such Indemnitees shall be represented by the same legal counsel (which may be a law firm engaged by the Indemnitees or attorneys employed by an Indemnitee or a combination of the foregoing) selected by the Indemnitees and reasonably acceptable to Borrower; provided, that if such legal counsel determines in good faith that representing all such Indemnitees would or could result in a conflict of interest under Laws or ethical principles applicable to such legal counsel or that a defense or counterclaim is available to an Indemnitee that is not available to all such Indemnitees, then to the extent reasonably necessary to avoid such a conflict of interest or to permit unqualified assertion of such a defense or counterclaim, each affected Indemnitee shall be entitled to separate representation by legal counsel selected by that Indemnitee and reasonably acceptable to Borrower, with all such legal counsel using reasonable efforts to avoid unnecessary duplication of effort by counsel for all Indemnitees; and further provided that the Administrative Agent (as an Indemnitee) shall at all times be entitled to representation by separate legal counsel (which may be a law firm or attorneys employed by the Administrative Agent or a combination of the foregoing). Any obligation or liability of Borrower to any Indemnitee under this Section 11.11 shall survive the expiration or termination of this Agreement and all Letters of Credit and the repayment of all Loans and the payment and performance of all other Obligations owed to the Banks.

     11.12 Nonliability of the Banks. Borrower acknowledges and agrees that:

          (a) Any inspections of any Property of Borrower or any other Loan Party made by or through the Administrative Agent or the Banks are for purposes of administration of the Loan only and Borrower and such other Loan Parties are not entitled to rely upon the same (whether or not such inspections are at the expense of Borrower);

          (b) By accepting or approving anything required to be observed, performed, fulfilled or given to the Administrative Agent or the Banks pursuant to the Loan Documents, neither the Administrative Agent nor the Banks shall be deemed to have warranted or represented the sufficiency, legality, effectiveness or legal effect of the same, or of any term, provision or condition thereof, and such acceptance or approval thereof shall not constitute a warranty or representation to anyone with respect thereto by the Administrative Agent or the Banks;

- 73 -

          (c) The relationship between Borrower and the Administrative Agent and the Banks is, and shall at all times remain, solely that of borrowers and lenders; neither the Administrative Agent nor the Banks shall under any circumstance be construed to be partners or joint venturers of Borrower or any other member of the Consolidated Group, neither the Administrative Agent nor the Banks shall under any circumstance be deemed to be in a relationship of confidence or trust or a fiduciary relationship with Borrower or any other member of the Consolidated Group, or to owe any fiduciary duty to Borrower or any other member of the Consolidated Group; neither the Administrative Agent nor the Banks undertake or assume any responsibility or duty to Borrower or any other member of the Consolidated Group, to select, review, inspect, supervise, pass judgment upon or inform Borrower or any other member of the Consolidated Group, of any matter in connection with their Property or the operations of Borrower or any other member of the Consolidated Group; Borrower and such other members shall rely entirely upon their own judgment with respect to such matters; and any review, inspection, supervision, exercise of judgment or supply of information undertaken or assumed by the Administrative Agent or the Banks in connection with such matters is solely for the protection of the Administrative Agent and the Banks and neither Borrower nor any other Person is entitled to rely thereon; and

          (d) The Administrative Agent and the Banks shall not be responsible or liable to any Person for any loss, damage, liability or claim of any kind relating to injury or death to Persons or damage to Property caused by the actions, inaction or negligence of Borrower and/or any other member of the Consolidated Group, and Borrower hereby indemnifies and holds the Administrative Agent and the Banks harmless on the terms set forth in Section 11.11 from any such loss, damage, liability or claim.

     11.13 No Third Parties Benefited. This Agreement is made for the purpose of defining and setting forth certain obligations, rights and duties of Borrower, the Administrative Agent and the Banks in connection with the Loans and Letters of Credit, and is made for the sole benefit of Borrower, the Administrative Agent and the Banks, and the Administrative Agent’s and the Banks’ successors and assigns. Except as provided in Sections 11.8, 11.11 and 11.22 no other Person shall have any rights of any nature hereunder or by reason hereof.

     11.14 Confidentiality.

          (a) Confidentiality. Each Bank and the Administrative Agent (each, a “Lender Party”) hereby agrees for itself only that, except as specifically set forth herein, such Lender Party (i) shall not participate in or generate any press release or other release of information to the general public relating to the closing of the Loan without the prior written consent of Borrower, (ii) shall hold the Confidential Information in strict confidence in accordance with such Lender Party’s customary procedures to prevent the misuse or disclosure of confidential information of this nature and in accordance with safe and sound banking practices, (iii) shall use the Confidential Information solely for the purposes of underwriting the Loan or acquiring an interest therein, carrying out such Lender Party’s rights or obligations under this Agreement, in connection with the syndication of the Loan, the enforcement of the Loan Documents, or other internal examination, supervision or oversight of the transactions contemplated hereby as reasonably determined by such Lender Party, or as otherwise permitted by the terms of this Section 11.14 (collectively, “Permitted Purposes”), and (iv) shall not disclose the Confidential Information to any third party, except as expressly authorized in this Agreement or with prior written consent of Borrower. Each Lender Party shall

- 74 -

promptly notify Borrower in the event that it becomes aware of any loss or unauthorized disclosure of any Confidential Information.

Each Lender Party shall not have any obligations under this Agreement with respect to a specific portion of the Confidential Information if such Lender Party can demonstrate that such Confidential Information (i) was publicly available at the time it was disclosed to such Lender Party, (ii) became publicly available subsequent to the time it was disclosed to such Lender Party (except to the extent such public availability was the result of such Lender Party’s disclosure), (iii) was in or comes into a Lender Party’s possession from a source not known to such Lender Party (after reasonable inquiry) to be in breach of an obligation of confidentiality owed to Borrower in making such disclosure to such Lender Party, (iv) was in or comes into Lender Party’s possession free of any obligation of confidence owed to Borrower at the time it was disclosed to such Lender Party, or (v) was developed by the employees or agents of the Lender Party without the use of the Confidential Information.

          (b) Disclosures. Any Lender Party or its legal counsel may disclose the Confidential Information (i) to Borrower, other Banks, the Administrative Agent or any of their respective legal counsel, (ii) to its auditors in connection with bank audits or regulatory officials having jurisdiction over such Lender Party, (iii) to its legal counsel who need to know the Confidential Information for the purposes of representing or advising the Lender Parties, (iv) to its consultants, agents and advisors retained in good faith by such Lender Party with a need to know such information in connection with a Permitted Purpose or to otherwise advise or consult with such Lender Party, (v) as required by Law or legal process (subject to the terms below), or in connection with any legal proceeding to which that Lender Party and any Loan Party are adverse parties (and Borrower hereby acknowledges and agrees that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001) (the “Act”), each Bank is required to obtain, verify and record information that identifies the Loan Parties, which information includes the name and address of the Loan Parties and other information that will allow such Bank to identify the Loan Parties in accordance with the Act), (vi) to another potential Bank or participant in connection with an assignment or proposed assignment to that Person of all or part of that Lender Party’s interests hereunder or a participation interest in its Notes, and (vii) to its directors, officers, employees and Affiliates who need to know the Confidential Information for purposes of underwriting the Loan or becoming a party to this Agreement, the syndication of the Loan, the administration, interpretation, performance or exercise of rights under the Loan Documents, the enforcement of the Loan Documents, or other internal supervision, examination or oversight of the transactions contemplated hereby as reasonably determined by such Lender Party, provided that any Person to whom any of the Confidential Information is disclosed is informed by such Lender Party of the strictly confidential nature of the Confidential Information, and such Persons described in clauses (b)(iv) and (vi) shall agree in writing to be bound by confidentiality restrictions at least as restrictive as those contained herein. Notwithstanding the foregoing, a Lender Party may disclose Confidential Information to the extent such Lender Party is requested or required by any Law or any order of any Governmental Agency or self regulatory body or other legal process to make any disclosure of or about any of the Confidential Information. In such event (except with respect to banking regulators or auditors), such Lender Party shall, if permitted by Law, promptly notify Borrower in writing so that Borrower may seek an appropriate protective order or waive compliance with the provisions of this Agreement (provided that if a protective order or the receipt of a waiver hereunder has not been obtained, or if prior notice is not possible, and a Lender Party is, in the opinion of its counsel, compelled to disclose Confidential Information, such Lender Party may

- 75 -

disclose that portion of the Confidential Information which its counsel advises it that such Lender Party is compelled to disclose, and provided further that in any event, such Lender Party will not oppose action by Borrower to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information.) Each Lender Party shall be liable (but only to the extent it is finally determined to have breached the provisions of this Section 11.14(b)) for any actions by such Lender Party (but not any other Person) which are not in accordance with the provisions of this Section 11.14(b).

Notwithstanding anything herein to the contrary, Confidential Information shall not include, and Administrative Agent and each Bank may disclose to any and all Persons, without limitation of any kind, any information with respect to the “tax treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011 4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or any Bank relating to such tax treatment and tax structure; provided that with respect to any document or similar item that in either case contains information concerning the tax treatment or tax structure of the transaction as well as other information, this sentence shall only apply to such portions of the document or similar item that relate to the tax treatment or tax structure of the Loans, the Letters of Credit and transactions contemplated hereby.

          (c) No Rights in Confidential Information. The Administrative Agent and each Bank recognizes and agrees that nothing contained in this Section 11.14 shall be construed as granting any property rights, by license or otherwise, to any Confidential Information (other than the Agreement or any amendments thereto or any related agreements), or to any invention or any patent, copyright, trademark, or other intellectual property right that has issued or that may issue, based on such Confidential Information (other than the Agreement or any amendments thereto or any related agreements). No Lender Party shall make, have made, use or sell for any purpose any product or other item using, incorporating or derived from any such Confidential Information; provided that the foregoing shall not limit or restrict in any way the creation, use or sale of banking or related services by any Lender Party.

          (d) Survival. All Confidential Information provided by or on behalf of Borrower during the term of this Agreement or any predecessor agreements shall remain confidential indefinitely and shall continue to receive that level of confidential treatment customarily provided by commercial banks dealing with confidential information of their borrower customers, subject, however, to the specific exceptions to confidential treatment provided herein. For a period of one year after the Termination Date, the affected Lender Party shall continue to make reasonable inquiry of any third party providing Confidential Information as to whether such third party is subject to an obligation of confidentiality owed to Borrower or its Subsidiaries and if such Lender Party obtains knowledge that such third party is violating a confidentiality agreement with Borrower, such Lender Party shall treat the Confidential Information received from such third party as strictly confidential in accordance with the provisions of this Section 11.14. For purposes of this Section 11.14(d), the “Termination Date” shall mean the earlier of the termination of this Agreement or, with respect to a specific Lender Party, the date such Person no longer holds an interest in the Loan.

          (e) Injunctive Relief. Each Lender Party hereby agrees that breach of this Section 11.14 will cause Borrower irreparable damage for which recovery of damages would be inadequate, and that Borrower shall therefore be entitled to obtain timely injunctive relief under this Agreement, as well as such further relief as may be granted by a court of competent jurisdiction.

- 76 -

          (f) No Fiduciary Duty. Nothing in this Section shall be construed to create or give rise to any fiduciary duty on the part of the Administrative Agent or the Banks to Borrower.

          (g) Separate Action. Borrower covenants and agrees not to, and hereby expressly waives any right to, raise as a defense, affirmative defense, set off, recoupment or otherwise against any Lender Party any claim arising from or relating to an alleged breach of this Section 11.14 in any action, claim or proceeding relating to a breach of the Loan Documents by Borrower or other action to enforce or recover the Obligations, and covenant and agree that any claim against a Lender Party arising from or relating to an alleged breach of this Section 11.14 by a Lender Party shall only be asserted as an affirmative claim in a separate action against the applicable Lender Party.

     11.15 Further Assurances. Borrower shall, at its expense and without expense to the Banks or the Administrative Agent, do, execute and deliver such further acts and documents as the Requisite Banks or the Administrative Agent from time to time reasonably require for the assuring and confirming unto the Banks or the Administrative Agent of the rights hereby created or intended now or hereafter so to be, or for carrying out the intention or facilitating the performance of the terms of any Loan Document.

     11.16 Integration. This Agreement, together with the other Loan Documents, comprises the complete and integrated agreement of the parties on the subject matter hereof and supersedes all prior agreements, written or oral, on the subject matter hereof. In the event of any conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control and govern; provided that the inclusion of supplemental rights or remedies in favor of the Administrative Agent or the Banks in any other Loan Document shall not be deemed a conflict with this Agreement. Each Loan Document was drafted with the joint participation of the respective parties thereto and shall be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof.

     11.17 Governing Law. Except to the extent otherwise provided therein, each Loan Document shall be governed by, and construed and enforced in accordance with, the Laws of the State of New York without any regard to conflicts of law principles that would result in the application of any Law other than the Laws of the State of New York.

     11.18 Severability of Provisions. Any provision in any Loan Document that is held to be inoperative, unenforceable or invalid as to any party or in any jurisdiction shall, as to that party or jurisdiction, be inoperative, unenforceable or invalid without affecting the remaining provisions or the operation, enforceability or validity of that provision as to any other party or in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable.

     11.19 Headings. Article and Section headings in this Agreement and the other Loan Documents are included for convenience of reference only and are not part of this Agreement or the other Loan Documents for any other purpose.

     11.20 Time of the Essence. Time is of the essence of the Loan Documents.

     11.21 Delivery of Tax Forms. Each Bank that is incorporated or otherwise organized under the Laws of a jurisdiction other than the United States of America or any State thereof or the District of Columbia shall deliver to Borrower (with a copy to the Administrative Agent), on or

- 77 -

before the Closing Date (or on or before accepting an assignment or receiving a participation interest herein pursuant to Section 11.8, if applicable) two duly completed copies, signed by a Responsible Official, of either Form W 8BEN (relating to such Bank and entitling it to a complete exemption from withholding on all payments to be made to such Bank by Borrower pursuant to this Agreement) or Form W 8ECI (relating to all payments to be made to such Bank by Borrower pursuant to this Agreement), or W-8IMY, as applicable, of the United States of America Internal Revenue Service or such other evidence satisfactory to Borrower and the Administrative Agent that no withholding under the federal income tax laws is required with respect to such Bank. If a Bank is claiming a “portfolio interest exemption,” such Bank shall, in addition to Form W 8BEN, provide a certificate signed by a Responsible Official to the effect that (i) such Bank is not a bank within the meaning of Section 881(c)(3)(A) of the Code, (ii) such Bank is not a 10% shareholder of Borrower, and (iii) such Bank is not related to Borrower within the meaning of Section 881(c)(3)(C) of the Code. Thereafter and from time to time, including before the expiration of any previously delivered form, each such Bank shall (a) promptly submit to Borrower (with a copy to the Administrative Agent), such additional duly completed and signed copies of one of such forms (or such successor forms as shall be adopted from time to time by the relevant United States of America taxing authorities) as may then be required under then current United States of America Laws and regulations to avoid, or such evidence as is satisfactory to Borrower and the Administrative Agent of any available exemption from, United States of America withholding taxes in respect of all payments to be made to such Bank by Borrower pursuant to this Agreement and (b) take such steps as shall not be materially disadvantageous to it, in the reasonable judgment of such Bank, and as may be reasonably necessary (including the re designation of its LIBOR Lending Office, if any) to avoid any applicable deduction or withholding for taxes from amounts payable to such Bank. In the event that Borrower or the Administrative Agent become aware that a participation has been granted pursuant to Section 11.8(e) to a financial institution that is incorporated or otherwise organized under the Laws of a jurisdiction other than the United States of America, any State thereof or the District of Columbia, then, upon request made by Borrower or the Administrative Agent to the Bank which granted such participation, such Bank shall cause such participant financial institution to deliver the same documents and information to Borrower and the Administrative Agent as would be required under this Section if such financial institution were a Bank. Each Bank that is a United States of America Person shall, upon the reasonable request of Borrower, deliver Form W-9 on or before the Closing Date (or on or before accepting an assignment or receiving a participation pursuant to Section 11.8, if applicable) and before the expiration of a previously delivered form.

     11.22 Hazardous Material Indemnity. Borrower hereby agrees to indemnify, hold harmless and defend (by counsel reasonably satisfactory to the Administrative Agent) the Administrative Agent and each of the Banks and their Affiliates and their respective directors, officers, employees, agents, successors and assigns from and against any and all claims, losses, damages, liabilities, fines, penalties, charges, administrative and judicial proceedings and orders, judgments, remedial action requirements, enforcement actions of any kind, and all costs and expenses incurred in connection therewith (including but not limited to reasonable attorneys’ fees and the reasonably allocated costs of attorneys employed by the Administrative Agent or any Bank, and expenses to the extent that the defense of any such action has not been assumed by Borrower), arising directly or indirectly out of (i) the presence on, in, under or about any Projects of any Hazardous Materials, or any releases or discharges of any Hazardous Materials on, under or from any Projects and (ii) any activity carried on or undertaken on or off any Projects by Borrower or any Loan Party or any of their predecessors in title, whether prior to or during the term of this Agreement, and whether by

- 78 -

Borrower or any predecessor in title or any employees, agents, contractors or subcontractors thereof, or any third Persons at any time occupying or present on any Project, in connection with the handling, treatment, removal, storage, decontamination, clean up, transport or disposal of any Hazardous Materials at any time located or present on, in, under or about any Project. The foregoing indemnity shall further apply to any residual contamination on, in, under or about any Project, or affecting any natural resources, and to any contamination of any Project or natural resources arising in connection with the generation, use, handling, storage, transport or disposal of any such Hazardous Materials, and irrespective of whether any of such activities were or will be undertaken in accordance with applicable Laws, but the foregoing indemnity shall not apply to Hazardous Materials on any Project, the presence of which is caused by the Administrative Agent or the Banks. Borrower hereby acknowledges and agrees that, notwithstanding any other provision of this Agreement or any of the other Loan Documents to the contrary, the obligations of Borrower under this Section (and under Sections 4.17 and 5.10) shall be unlimited corporate obligations of Borrower and shall not be secured by any Lien on any Project. Any obligation or liability of Borrower to any Indemnitee under this Section 11.22 shall survive the expiration or termination of this Agreement and all Letters of Credit and the repayment of all Loans and the payment and performance of all other Obligations owed to the Banks.

     11.23 [Intentionally Omitted].

     11.24 Removal of a Bank. Borrower shall have the right to remove a Bank as a party to this Agreement if (a) such Bank is paid a material amount by Borrower pursuant to Section 3.4 or Section 3.5, (b) any of the events described in Section 9.1(j) occurs with respect to such Bank, or (c) such Bank becomes (and at the time of the proposed removal hereunder remains) a Defaulting Bank hereunder. Upon notice from Borrower, such Bank shall execute and deliver a Commitment Assignment and Acceptance covering that Bank’s Percentage of the Commitments in favor of such Eligible Assignee as Borrower may designate with the approval of the Administrative Agent, subject to payment in full by such Eligible Assignee of all principal, interest and fees and any other amount owing to such Bank through the date of assignment. The removal of any Defaulting Bank pursuant to this Section 11.24 shall not preclude Borrower from pursuing all remedies available to it against such Defaulting Bank for damages arising out of such Defaulting Bank’s breach hereof.

     11.25 Waiver Of Right To Trial By Jury. Each party to this agreement hereby expressly waives any right to trial by jury of any claim, demand, action or cause of action arising under any loan document or in any way connected with or related or incidental to the dealings of the parties hereto or any of them with respect to any loan document, or the transactions related thereto, in each case whether now existing or hereafter arising, and whether sounding in contract or tort or otherwise; and each party hereby agrees and consents that any such claim, demand, action or cause of action shall be decided by court trial without a jury, and that any party to this agreement may file an original counterpart or a copy of this section with any court as written evidence of the consent of the signatories hereto to the waiver of their right to trial by jury.

     11.26 Purported Oral Amendments. Borrower expressly acknowledges that this agreement and the other loan documents may only be amended or modified, or the provisions hereof or thereof waived or supplemented, by an instrument in writing that complies with section 12.1. Borrower agrees that it will not rely on any course of

- 79 -

dealing, course of performance, or oral or written statements by any representative of the administrative agent or any bank that does not comply with section 12.1 to effect an amendment, modification, waiver or supplement to this agreement or the other loan documents.

     11.27 Replacement of Notes. Upon receipt of evidence reasonably satisfactory to Borrower of the loss, theft, destruction or mutilation of any Note, and in the case of any such loss, theft or destruction, upon delivery of an indemnity agreement reasonably satisfactory to Borrower or, in the case of any such mutilation, upon surrender and cancellation of the applicable Note, Borrower will execute and deliver, in lieu thereof, a replacement Note, identical in form and substance to the applicable Note and dated as of the date of the applicable Note and upon such execution and delivery all references in the Loan Documents to such Note shall be deemed to refer to such replacement Note.

     11.28 Defaulting Banks. In the event that any Bank becomes a Defaulting Bank, then, in addition to any rights and remedies that may be available to Borrower or the other Banks and the Administrative Agent (such other Banks and the Administrative Agent being called “Non Defaulting Banks”) at law or in equity:

          (a) The Defaulting Bank’s rights to participate in the administration of the Loan and the Loan Documents, including any right to vote upon, approve, disapprove, consent to or direct any action of the Administrative Agent (other than amendments to the Loan Documents directly affecting the Defaulting Bank’s Commitment), shall be suspended and such rights shall not be reinstated unless and until such Bank ceases to be a Defaulting Bank (and all decisions, except the decision to remove the Administrative Agent, which are to be based on a vote of the Requisite Banks or all Banks shall be resolved based upon a decision or determination made by the required percentage of the Non-Defaulting Banks); provided, however, that if the Administrative Agent is a Defaulting Bank, the Administrative Agent shall continue to have all rights provided for in this Loan Agreement, as the Administrative Agent only, with respect to the administration of the Loan unless it is removed and replaced as the Administrative Agent as provided in Section 10.8.

          (b) Any or all of the Non-Defaulting Banks shall be entitled (but shall not be obligated) to: (i) fund the aggregate amount that the Defaulting Bank has failed to fund or pay to the Administrative Agent (such amount being called the “Defaulted Amount”); and (ii) collect interest at the Default Rate on the Defaulted Amount (after crediting all interest actually paid by Borrower on the Defaulted Amount from time to time), either directly from the Defaulting Bank or from amounts otherwise payable to the Defaulting Bank, for the period from the date on which the Defaulted Amount was funded by the Non-Defaulting Banks until the date on which payment is made. If the Administrative Agent has funded the Defaulted Amount, the Administrative Agent shall be entitled to collect interest at the Default Rate from the Defaulting Bank on the Defaulted Amount as set forth above, as if the Administrative Agent were a Non-Defaulting Bank that had elected to fund the Defaulted Amount.

          (c) In the event the Defaulted Amount is funded by any Non-Defaulting Banks or the Administrative Agent pursuant to Section 11.28(b) above, the Defaulting Bank’s interest in the Loans, the Loan Documents and proceeds thereof shall be subordinated to any Defaulted Amount funded by any Non-Defaulting Banks or the Administrative Agent pursuant to Section 11.28(b) above, plus all interest which may be due in accordance with Section 11.28(b) above (to be applied pari passu among the Non-Defaulting Banks (including the Administrative

- 80 -

Agent, unless the Administrative Agent is the Defaulting Bank) funding the Defaulted Amount), without necessity for executing any further documents; provided that such Defaulting Bank’s interest in the Loan, the Loan Documents and the proceeds thereof shall no longer be so subordinated if the Defaulted Amount funded by the Non-Defaulting Banks or the Administrative Agent (and all interest which has accrued pursuant to Section 11.28(b) above) shall be repaid in full.

          (d) If, following the payment in full of all amounts due pursuant to Section 11.28(c) above to the Non-Defaulting Banks (including the Administrative Agent, unless the Administrative Agent is the Defaulting Bank) which have funded all or any portion of any Defaulted Amount, there remains any unfunded Defaulted Amount which has not been funded by the Non-Defaulting Banks, the Administrative Agent or the Defaulting Bank (“Unfunded Defaulted Amount”), then a portion of the Defaulting Bank’s interest in the Loan, the Loan Documents and the proceeds thereof equal to the amount of the Unfunded Defaulted Amount (together with interest thereon at the rate applicable to the Defaulted Amount from time to time pursuant to the Loan Documents) shall be subordinated to the interests of the Non-Defaulting Banks (including the Administrative Agent, unless the Administrative Agent is the Defaulting Bank) unless and until such Unfunded Defaulted Amount is funded either by one or more Non -Defaulting Banks, the Administrative Agent or the Defaulting Bank.

          (e) Subject to the provisions of Section 11.8 and the definition of Eligible Assignee, each Non-Defaulting Bank will have the right, but not the obligation, in its sole discretion, to acquire at par all or a proportionate share (based on the ratio of its Commitments to the aggregate amount of the Commitments of all of the Non-Defaulting Banks that elect to acquire a share of the Defaulting Bank’s Commitment of the Defaulting Bank’s Commitment, including without limitation its proportionate share in the outstanding principal balance of the Loan, and all rights and interests of the Defaulting Bank under this Agreement and the other Loan Documents.

          (f) Nothing herein contained shall be deemed or construed to waive, diminish, limit, prevent or estop the Administrative Agent, Borrower or any Bank from exercising or enforcing any rights or remedies which may be available at law or in equity as a result of or in connection with any default under this Agreement by a Bank (including the right to bring suit against the Defaulting Bank to recover the Defaulted Amount and interest thereon at the rate provided in this Section 11.28).
