ARTICLE II

THE CREDIT

2.1 Commitment. From and including the date of this Agreement and prior to the Facility Termination Date, each Lender severally agrees, subject to the terms and conditions set forth in this Agreement, to make Loans to the Borrower from time to time prior to the Facility Termination Date, provided that the making of any such Loan will not cause the total of the outstanding principal balance of all Loans (including Swing Line Loans and Competitive Bid Loans) and the Facility Letter of Credit Obligations to exceed the Aggregate Commitment. Except for Swing Line Loans and Competitive Bid Loans each Lender shall fund its Percentage of each Advance and no Lender will be required to fund any amount, which when aggregated with such Lender’s Percentage of: (i) all other Advances (other than Competitive Bid Loans) then outstanding, (ii) Facility Letter of Credit Obligations, and (iii) all Swing Line Loans, would exceed such Lender’s Commitment. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow at any time prior to the Facility Termination Date. The Commitments of each Lender to lend hereunder shall expire on the Facility Termination Date. The Aggregate Commitment may be increased from time to time by the addition of a new Lender or the increase of the Commitment of an existing Lender with the consent of only the Borrower, the Administrative Agent, and the new or existing Lender providing such additional Commitment so long as the Aggregate Commitment does not exceed $600,000,000 less any voluntary reductions pursuant to Section 2.7. Such increases shall be evidenced by the execution and delivery of an Amendment Regarding Increase in the form of Exhibit J attached hereto by the Borrower, the Administrative Agent and the new Lender or existing Lender providing such additional Commitment, a copy of which shall be forwarded to each Lender by the Administrative Agent promptly after execution thereof. On the effective date of each such increase in the Aggregate Commitment, the Borrower and the Administrative Agent shall cause the new or existing Lenders providing such increase to hold its or their Percentage of all ratable Advances outstanding at the close of business on such day, by either funding more than its or their Percentage of new ratable Advances made on such date or purchasing shares of outstanding ratable Loans held by the other Lenders or a combination thereof. The Lenders agree to cooperate in any required sale and purchase of outstanding ratable Advances to achieve such result. Borrower agrees to pay all fees associated with the increase in the Aggregate Commitment including any amounts due under Section 4.4 in connection with any reallocation of LIBOR Advances. In no event will such new or existing Lenders providing the increase be required to fund or purchase a portion of any Competitive Bid Loan or Swingline Loan to comply with this Section on such date.

2.2 Final Principal Payment. Any outstanding Advances and all other unpaid Obligations shall be paid in full by the Borrower on the Facility Termination Date.

2.3 Loans. Each Advance hereunder shall consist of Loans made from the several Lenders ratably in proportion to the ratio that their respective Commitments bear to the Aggregate Commitment except for Swing Line Loans which shall be made by the Swing Line Lender in accordance with Section 2.14 and Competitive Bid Loans made in accordance with Section 2.15. The Advances may be ABR Advances or LIBOR Advances, or a combination thereof, selected by the Borrower in accordance with Sections 2.10 and 2.11.

2.4 Applicable Margins. The ABR Applicable Margin and the LIBOR Applicable Margin to be used in calculating the interest rate applicable to different Types of Advances shall vary from time to time in accordance with the long-term unsecured debt ratings from Moody’s, Fitch and S&P of the General Partner and the Borrower. In the event the General Partner and the Borrower have different ratings, the rating of the higher rated entity shall be used. In the event the rating agencies are split on the rating for the higher rated entity, the second highest rating for such entity shall be deemed to be the applicable rating (e.g., if the higher rated entity’s Moody’s debt rating is Baa1, its S&P debt rating is BBB and its Fitch’s rating is BBB, then the Applicable Margins shall be computed based on the S&P rating), and the Applicable Margins shall be adjusted effective on the next Business Day following any change in the higher rated entity’s Moody’s

debt rating, S&P’s debt rating and/or Fitch’s debt rating, as the case may be. The applicable debt ratings and the Applicable Margins are set forth in the table attached as Exhibit A. In the event that S&P, Fitch or Moody’s or any two of them shall discontinue their ratings of the REIT industry, the General Partner or the Borrower, a mutually agreeable substitute rating agency (or two mutually agreeable substitute agencies if two of the existing rating agencies discontinue such ratings) shall be selected by the Required Lenders and the Borrower. If the Required Lenders and the Borrower cannot agree on a substitute rating agency or substitute rating agencies within thirty (30) days of such discontinuance, or if S&P, Fitch, and Moody’s shall discontinue their ratings of the REIT industry, the Borrower, or the General Partner, the Applicable Margin to be used for the calculation of interest on Advances hereunder shall be the highest Applicable Margin for each Type.

If a rating agency downgrade or discontinuance results in an increase in the ABR Applicable Margin, the LIBOR Applicable Margin, or Facility Fee Rate and if such increase is reversed and the affected Applicable Margin is restored within ninety (90) days thereafter, at the Borrower’s request, the Borrower shall receive a credit against interest next due the Lenders equal to interest accrued from time to time during such period of downgrade or discontinuance and actually paid by the Borrower on the Advances at the differential between such Applicable Margins, and the differential of the Facility Fee paid during such period of downgrade.

If a rating agency upgrade results in a decrease in the ABR Applicable Margin, LIBOR Applicable Margin or Facility Fee Rate and if such upgrade is reversed and the affected Applicable Margin is restored within ninety (90) days thereafter, Borrower shall be required to pay an amount to the Lenders equal to the interest differential on the Advances and the differential on the Facility Fees during such period of upgrade.

2.5 Facility Fee. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a facility fee (the “Facility Fee”) calculated at a per annum percentage (“Facility Fee Rate”) of the total Aggregate Commitment. The Facility Fee Rate shall vary from time to time based on the Borrower’s or General Partner’s long term unsecured debt rating as set forth in the table attached hereto as Exhibit A, and determined in a manner consistent with the provisions of Section 2.4 relating to Applicable Margins, and the Facility Fee shall be payable quarterly in arrears on the last day of each calendar quarter hereafter beginning March 31, 2001 and on the Facility Termination Date.

2.6 Other Fees. The Borrower will pay to Administrative Agent for the benefit of the Lenders on or before the date hereof the fees specified in that certain Fee Letter dated November 27, 2000.

2.7 Voluntary Reduction of Aggregate Commitment Amount. Upon at least fifteen (15) days prior irrevocable written notice (or telephone notice promptly confirmed in writing) to the Administrative Agent, Borrower shall have the right, without premium or penalty, to terminate permanently the Aggregate Commitment in whole or in part provided that (a) Borrower may not reduce the Aggregate Commitment below the Allocated Facility Amount at the time of such requested reduction, and (b) any such partial termination shall be in the minimum aggregate amount of Five Million Dollars ($5,000,000.00) or any integral multiple of Five Million Dollars ($5,000,000.00) in excess thereof. Any partial termination of the Aggregate Commitment shall be applied pro rata to each Lender’s Commitment.

2.8 Minimum Amount of Each Advance. Each LIBOR Advance shall be in the minimum amount of $2,000,000 (and in multiples of $1,000,000 if in excess thereof), and each ABR Advance shall be in the minimum amount of $1,000,000 (and in multiples of $500,000 if in excess thereof), provided, however, that any ABR Advance may be in the amount of the unused Aggregate Commitment.

2.9 Optional Principal Payments. The Borrower may from time to time pay, without penalty or premium, all or any part of outstanding ABR Advances upon two Business Days’ prior notice to the Administrative Agent. The Borrower may from time to time pay a LIBOR Advance, provided a LIBOR Advance may not be paid prior to the last day of the

applicable Interest Period unless accompanied by any amount due pursuant to Section 4.4. A Competitive Bid Loan may not be paid prior to its maturity, provided, however, that if a Competitive Bid Loan becomes due prior to its stated maturity due to acceleration of the Obligations, then payment of such Competitive Bid Loan shall be accompanied by any amount due pursuant to Section 4.4.

2.10 Method of Selecting Types and Interest Periods for New Advances. The Borrower shall select the Type of Advance and, in the case of each LIBOR Advance, the Interest Period applicable to each Advance from time to time. The Borrower shall give the Administrative Agent irrevocable notice (a “Borrowing Notice”) (i) not later than 10:00 a.m. Chicago time, at least one (1) Business Day before the Borrowing Date of each ABR Advance, (ii) not later than 10:00 a.m. Chicago time, at least three (3) Business Days before the Borrowing Date for each LIBOR Advance, and (iii) not later than 11:00 a.m. Chicago time on the Borrowing Date for each Swing Line Loan, specifying:

(a) the Borrowing Date, which shall be a Business Day, of such Advance,

(b) the aggregate amount of such Advance,

(d) in the case of each LIBOR Advance, the Interest Period applicable thereto.

Not later than noon (Chicago time) on each Borrowing Date, each Lender shall make available its Loan or Loans, in funds immediately available in Chicago to the Administrative Agent at its address specified pursuant to Article XIV. The Lenders shall not be obligated to match fund their LIBOR Advances. The Administrative Agent will make the funds so received from the Lenders available to the Borrower at the Administrative Agent’s aforesaid address.

No Interest Period may end after the Facility Termination Date and, unless all of the Lenders otherwise agree in writing, in no event may there be more than seven (7) different Interest Periods for LIBOR Advances (other than Competitive Bid Loans) outstanding at any one time.

2.11 Conversion and Continuation of Outstanding Advances. ABR Advances shall continue as ABR Advances unless and until such ABR Advances are converted into LIBOR Advances. Each LIBOR Advance shall continue as a LIBOR Advance until the end of the then applicable Interest Period therefor, at which time such LIBOR Advance shall be automatically converted into an ABR Advance unless the Borrower shall have given the Administrative Agent a Conversion/Continuation Notice requesting that, at the end of such Interest Period, such LIBOR Advance continue as a LIBOR Advance for the same or another Interest Period. Subject to the terms of Section 2.8, the Borrower may elect from time to time to convert all or any part of an Advance of any Type into any other Type of Advance; provided that any conversion of any LIBOR Advance shall be made on, and only on, the last day of the Interest Period applicable thereto. The Borrower shall give the Administrative Agent irrevocable notice (a “Conversion/Continuation Notice”) of each conversion of an Advance or continuation of a LIBOR Advance not later than 10:00 a.m. (Chicago time) at least one Business Day, in the case of a conversion into an ABR Advance, or three Business Days, in the case of a conversion into or continuation of a LIBOR Advance, prior to the date of the requested conversion or continuation, specifying:

(i) the requested date which shall be a Business Day, of such conversion or continuation;

(ii) the aggregate amount and Type of the Advance which is to be converted or continued; and

(iii) the amount and Type(s) of Advance(s) into which such Advance is to be converted or continued and, in the case of a conversion into or continuation of a LIBOR Advance, the duration of the Interest Period applicable thereto.

2.12 Changes in Interest Rate, Etc. Each ABR Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Advance is made or is converted from a LIBOR Advance into a ABR Advance pursuant to Section 2.11 to but excluding the date it becomes due or is converted into a LIBOR Advance pursuant to Section 2.11 hereof, at a rate per annum equal to the ABR Rate for such day. Changes in the rate of interest on that portion of any Advance maintained as a ABR Advance will take effect simultaneously with each change in the Alternate Base Rate. Each LIBOR Advance shall bear interest from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the interest rate determined as applicable to such LIBOR Advance.

2.13 Rates Applicable After Default. Notwithstanding anything to the contrary contained in Section 2.10 or 2.11, during the continuance of a Default or Unmatured Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 9.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that no Advance may be made as, converted into or continued beyond its current term as a LIBOR Advance. During the continuance of a Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 9.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that (i) each LIBOR Advance shall bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable to such Interest Period plus 2% per annum and (ii) each ABR Advance shall bear interest at a rate per annum equal to the ABR Rate otherwise applicable to the ABR Advance plus 2% per annum and the Facility Letter of Credit Fee shall increase by 2% per annum; provided that such rates and increase in the Facility Letter of Credit Fee shall become applicable automatically without notice to the Borrower or an election or action by the Administrative Agent or any Lender if a Default occurs under Section 8.7 or Section 8.8, or a Default occurs relating to the payment of principal or interest unless waived by the Required Lenders.

2.14 Swing Line Loans. In addition to the other options available to Borrower hereunder, up to $40,000,000 of the Swing Line Lender’s Commitment, shall be available for Swing Line Loans subject to the following terms and conditions. Swing Line Loans shall be made available for same day borrowings provided that notice is given in accordance with Section 2.10 hereof. All Swing Line Loans shall bear interest at the ABR Rate. In no event shall the Swing Line Lender be required to fund a Swing Line Loan if it would increase the total aggregate outstanding Loans by Swing Line Lender hereunder plus its Percentage of Facility Letter of Credit Obligations to an amount in excess of its Commitment or if it would cause the Allocated Facility Amount to exceed the Aggregate Commitment. Each Swing Line Loan shall be paid in full by the Borrower on or before the fifth (5th) day after the Borrowing Date for such Swing Line Loan. In addition, the Swing Line Lender (i) may at any time in its sole discretion with respect to any outstanding Swing Line Loan, or (ii) shall on the fifth (5th) day after the Borrowing Date of any Swing Line Loan, require each Lender (including the Swing Line Lender) to make a Loan in the amount of such Lender’s Percentage of such Swing Line Loan (including, without limitation, any interest accrued and unpaid thereon), for the purpose of repaying such Swing Line Loan. Not later than noon (Chicago time) on the date of any notice received pursuant to this Section 2.14, each Lender shall make available its required Loan, in funds immediately available in Chicago to the Administrative Agent at its address specified pursuant to Article XIV. Revolving Loans made pursuant to this Section 2.14 shall initially be ABR Loans and thereafter may be continued as ABR Loans or converted into LIBOR Loans in the manner provided in Section 2.11 and subject to the other conditions and limitations set forth in this Article II. Unless a Lender shall have notified the Swing Line Lender, prior to its making any Swing Line Loan, that any applicable condition precedent set forth in Sections 5.1 or 5.2 had not then been satisfied, such Lender’s obligation to make Loans pursuant to this Section 2.14 to repay Swing Line Loans shall be unconditional, continuing, irrevocable and absolute and shall not be affected by any circumstances, including, without limitation, (a) any set-off, counterclaim, recoupment, defense or other right which such Lender may have against the Administrative Agent, the Swing Line Lender or any other Person, (b) the occurrence or continuance of a Default or Unmatured Default, (c) any adverse change in the condition (financial or otherwise) of the Borrower, or (d) any other circumstances, happening or event whatsoever. In the event that any Lender fails to make payment to the Administrative Agent of any amount due under this Section 2.14, the Administrative Agent shall be entitled to receive, retain and apply against such obligation the principal and interest otherwise payable to such Lender hereunder until the Administrative

Agent receives such payment from such Lender or such obligation is otherwise fully satisfied. In addition to the foregoing, if for any reason any Lender fails to make payment to the Administrative Agent of any amount due under this Section 2.14, such Lender shall be deemed, at the option of the Administrative Agent, to have unconditionally and irrevocably purchased from the Swing Line Lender, without recourse or warranty, an undivided interest and participation in the applicable Swing Line Loan in the amount of such payment not made by such Lender, and such interest and participation may be recovered from such Lender together with interest thereon at the Federal Funds Effective Rate for each day during the period commencing on the date of demand and ending on the date such amount is received. Swing Line Loans may be outstanding for a maximum of ten (10) days during any calendar month. On the Facility Termination Date, the Borrower shall repay in full the outstanding principal balance of the Swing Line Loans.

The Administrative Agent shall promptly notify the Borrower of the terms (i) of any Competitive Bid Quote submitted by a Lender that is in accordance with Section 2.15(d) and (ii) of any Competitive Bid Quote that amends, modifies or is otherwise inconsistent with a previous Competitive Bid Quote submitted by such Lender with respect to the same Competitive Bid Quote Request. Any such subsequent Competitive Bid Quote shall be disregarded by the Administrative Agent unless such subsequent Competitive Bid Quote specifically states that it is submitted solely to correct a manifest error in such former Competitive Bid Quote. The Administrative Agent’s notice to the Borrower shall specify the aggregate principal amount of Competitive Bid Loans for which offers have been received for each Interest Period specified in the related Competitive Bid Quote Request and the respective principal amounts and Competitive LIBOR Margins or Absolute Rate, as the case may be, so offered.

(f) Acceptance and Notice by Borrower. Not later than (i) 10:00 a.m. (Chicago time) at least three Business Days prior to the proposed Borrowing Date in the case of a request for a Competitive LIBOR Margin or (ii) 10:00 a.m. (Chicago time) on the proposed Borrowing Date, in the case of a request for an Absolute Rate (or, in either case upon reasonable prior notice to the Lenders, such other time and date as the Borrower and the Administrative Agent may agree), the Borrower shall notify the Administrative Agent of its acceptance or rejection of the offers so notified to it pursuant to Section 2.15(e); provided, however, that the failure by the Borrower to give such notice to the Administrative Agent shall be deemed to be a rejection of all such offers. In the case of acceptance, such notice (a “Competitive Bid Borrowing Notice”) shall specify the aggregate principal amount of offers for each Interest Period that are accepted. The Borrower may accept any Competitive Bid Quote in whole or in part (subject to the terms of Section 2.15(d)(iii)); provided that:

(i) the aggregate principal amount of all Competitive Bid Loans to be disbursed on a given Borrowing Date may not exceed the applicable amount set forth in the related Competitive Bid Quote Request,

(ii) acceptance of offers may only be made on the basis of ascending Competitive LIBOR Margins or Absolute Rates, as the case may be, and

(iii) the Borrower may not accept any offer that is described in Section 2.15(d)(iii) or that otherwise fails to comply with the requirements of this Agreement.

(g) Allocation by Administrative Agent. If offers are made by two or more Lenders with the same Competitive LIBOR Margins or Absolute Rates, as the case may be, for a greater aggregate principal amount than the amount in respect of which offers are accepted for the related Interest Period, the principal amount of Competitive Bid Loans in respect of which such offers are accepted shall be allocated by the Administrative Agent among such Lenders as nearly as possible (in such multiples, not greater than $1,000,000, as the Administrative Agent may deem appropriate) in proportion to the aggregate principal amount of such offers provided, however, that no Lender shall be allocated any Competitive Bid Loan which is less than the minimum amount which such Lender has indicated that it is willing to accept. Allocations by the Administrative Agent of the amounts of Competitive Bid Loans shall be conclusive in the absence of manifest error. The Administrative Agent shall promptly, but in any event on the same Business Day, notify each Lender of its receipt of a Competitive Bid Borrowing Notice and the principal amounts of the Competitive Bid Loans allocated to each participating Lender.

(h) Administration Fee. The Borrower hereby agrees to pay to the Administrative Agent an administration fee of $2,500 per each Competitive Bid Quote Request transmitted by the Borrower to the Administrative Agent pursuant to Section 2.15(b). Such administration fee shall be payable monthly in arrears on the first Business Day of each month and on the Maturity Date (or such earlier date on which the Aggregate Commitment shall terminate or be cancelled) for any period then ending for which such fee, if any, shall not have been theretofore paid.

(i) Other Terms. Any Competitive Bid Loan shall not reduce the Commitment of the Lender making such Competitive Bid Loan, and each such Lender shall continue to be obligated to fund its full Percentage of all pro rata Advances under the Facility. In no event can the aggregate amount of all Competitive Bid Loans at any time exceed fifty

percent (50%) of the then Aggregate Commitment. Competitive Bid Loans shall not be prepaid prior to the end of the applicable Interest Period. Competitive Bid Loans may not be continued and, if not repaid at the end of the Interest Period applicable thereto, shall (subject to the conditions set forth in this Agreement) be replaced by new Competitive Bid Loans made in accordance with this Section 2.15 or by ratable Advances in accordance with Section 2.11.

(j) Designated Lenders. A Lender may designate its Designated Lender to fund a Competitive Bid Loan on its behalf as described in Section 2.15(d)(ii)(5). Any Designated Lender which funds a Competitive Bid Loan shall on and after the time of such funding become the obligee under such Competitive Bid Loan and be entitled to receive payment thereof when due. No Lender shall be relieved of its obligation to fund a Competitive Bid Loan, and no Designated Lender shall assume such obligation, prior to the time such Competitive Bid Loan is funded.

2.16 Method of Payment. All payments of the Obligations hereunder shall be made, without setoff, deduction, or counterclaim, in immediately available funds to the Administrative Agent at the Administrative Agent’s address specified pursuant to Article XIV, or at any other Lending Installation of the Administrative Agent specified in writing by the Administrative Agent to the Borrower, by noon (local time) on the date when due and shall be applied by the Administrative Agent among the Lenders in accordance with the class or type of Obligation being paid. Each payment delivered to the Administrative Agent for the account of any Lender shall be delivered by the Administrative Agent to such Lender in the same type of funds that the Administrative Agent received at its address specified pursuant to Article XIV or at any Lending Installation specified in a notice received by the Administrative Agent from such Lender promptly, which is expected to be by the close of business on the same Business Day received by Administrative Agent if received by noon (local time) but shall in any event not be later than the next Business Day, provided that the Administrative Agent shall pay to such Lenders interest thereon, at the lesser of (i) the Federal Funds Effective Rate and (ii) the rate of interest applicable to such Loans, from the Business Day such funds are received by the Administrative Agent in immediately available funds (provided, if such funds are not received by the Administrative Agent by noon (local time), such period shall commence on the Business Day immediately following the day such funds are received) until such funds are paid to such Lenders. The Administrative Agent is hereby authorized to charge the account of the Borrower maintained with Bank One for each payment of any of the Obligations as it becomes due hereunder.

2.17 Notes; Telephonic Notices. Each Lender is hereby authorized to record the principal amount of each of its Loans and each repayment on the schedule attached to its Note, provided, however, that the failure to so record shall not affect the Borrower’s obligations under such Note. Each Lender’s books and records, including without limitation, the information, if any, recorded by the Lender on the Schedule attached to its Note, shall be deemed to be prima facia correct. The Borrower hereby authorizes the Lenders and the Administrative Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices made by any person or persons the Administrative Agent or any Lender in good faith believes to be acting on behalf of the Borrower. The Borrower agrees to deliver promptly to the Administrative Agent a written confirmation signed by an Authorized Officer of each telephonic notice, if such confirmation is requested by the Administrative Agent or any Lender. If the written confirmation differs in any material respect from the action taken by the Administrative Agent and the Lenders, the records of the Administrative Agent and the Lenders shall govern absent manifest error.

2.18 Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Advance shall be payable on each Payment Date, commencing with the first such date to occur after the date hereof, and at maturity, whether by acceleration or otherwise. Interest accrued on each LIBOR Advance shall also be payable on any date on which the LIBOR Advance is prepaid (provided that nothing herein shall authorize a prepayment which is not otherwise permitted hereunder). Interest, Facility Fees and Facility Letter of Credit Fees shall be calculated for actual days elapsed on the basis of a 360–day year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon (local time) at the place of payment. If any payment of principal of or interest on an Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment.

2.19. Notification of Advances, Interest Rates and Prepayments. Promptly after receipt thereof (but in no event later than one Business Day prior to the proposed Borrowing Date for a ABR Advance or three Business Days prior to the proposed Borrowing Date for a LIBOR Advance) the Administrative Agent will notify each Lender of the contents of each Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. The Administrative Agent will notify each Lender of the interest rate applicable to each LIBOR Advance promptly upon determination of such interest rate and will give each Lender prompt notice of each change in the Alternate Base Rate.

2.20. Lending Installations. Each Lender may book its Loans and its participation in Facility Letters of Credit at any Lending Installation selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Notes shall be deemed held by each Lender for the benefit of such Lending Installation. Each Lender may, by written or telex notice to the Administrative Agent and the Borrower, designate a Lending Installation through which Loans will be made by it or Facility Letters of Credit will be issued by it and for whose account Loan payments or payments with respect to Facility Letters of Credit are to be made.

2.21. Non–Receipt of Funds by the Administrative Agent. Unless the Borrower or a Lender, as the case may be, notifies the Administrative Agent prior to the date on which it is scheduled to make payment to the Administrative Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal, interest or fees to the Administrative Agent for the account of the Lenders, that it does not intend to make such payment, the Administrative Agent may assume that such payment has been made. The Administrative Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Administrative Agent, the recipient of such payment shall, on demand by the Administrative Agent, repay to the Administrative Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Administrative Agent until the date the Administrative Agent recovers such amount at a rate per annum equal to (i) in the case of payment by a Lender, the Federal Funds Effective Rate for such day or (ii) in the case of payment by the Borrower, the interest rate applicable to the relevant Loan.

2.22. Usury. This Agreement and each Note are subject to the express condition that at no time shall the Borrower be obligated or required to pay interest on the principal balance of the Loan at a rate which could subject any Lender (including the Swing Line Lender or any Designated Lender) to either civil or criminal liability as a result of being in excess of the Maximum Legal Rate. If by the terms of this Agreement or the Loan Documents, the Borrower is at any time required or obligated to pay interest on the principal balance due hereunder at a rate in excess of the Maximum Legal Rate, the interest rate or the Default Rate, as the case may be, shall be deemed to be immediately reduced to the Maximum Legal Rate and all previous payments in excess of the Maximum Legal Rate shall be deemed to have been payments in reduction of principal and not on account of the interest due hereunder. All sums paid or agreed to be paid to a Lender for the use, forbearance, or detention of the sums due under the Loan, shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full stated term of the Loan until payment in full so that the rate or amount of interest on account of the Loan does not exceed the Maximum Legal Rate of interest from time to time in effect and applicable to the Loan for so long as the Loan is outstanding.

2.23. Applications of Moneys Received. All moneys collected or received by the Administrative Agent on account of the Facility directly or indirectly, shall be applied in the following order of priority:

(i) to the payment of all reasonable costs incurred in the collection of such moneys of which the Administrative Agent shall have given notice to the Borrower;

(ii) to the reimbursement of any yield protection due to the Lenders in accordance with Section 4.1;

(iii) to the payment of any fee due pursuant to Section 3.8(b) in connection with the issuance of a Facility Letter of Credit to the Issuing Bank, to the payment of the Facility Fee to the Lenders, if then due, in accordance with their Percentages and to the payment of the Administrative Agent's Fee to the Administrative Agent if then due;

(iv) (a) in case the entire unpaid principal of the Loan shall not have become due and payable, the whole amount received as interest and Facility Letter of Credit Fee then due to the Lenders (other than a Defaulting Lender) as their respective Percentages appear (except to the extent there are Swing Line Loans or Competitive Bid Loans outstanding in which event the full amount of interest attributable to the Swing Line Loans and Competitive Bid Loans shall be payable to the Swing Line Lender and Competitive Bid Lenders, respectively, unless the Swing Line Lender or Competitive Bid Lender shall be a Defaulting Lender), together with the whole amount, if any, received as principal first to the Swing Line Lender, unless the Swing Line Lender shall be a Defaulting Lender, to repay any outstanding Swing Line Loans and then to the Lenders as their respective Funded Percentages appear, or (b) in case the entire unpaid principal of the Loan shall have become due and payable, as a result of a Default or otherwise, to the payment of the whole amount then due and payable on the Loan for principal, together with interest thereon at the Default Rate or the interest rate, as applicable, to the Swing Line Lender, unless the Swing Line Lender shall be a Defaulting Lender, for all such amounts due in connection with Swing Line Loans and then to the Lenders (other than a Defaulting Lender) as their respective Funded Percentages appear until paid in full and then to the Letter of Credit Collateral Account until the full amount of Facility Letter of Credit Obligations is on deposit therein; and

(v) to the payment of any sums due to each Defaulting Lender as their respective Percentages appear (provided that Administrative Agent shall have the right to set-off against such sums any amounts due from such Defaulting Lender).

ARTICLE III

THE LETTER OF CREDIT SUBFACILITY

3.1. Obligations to Issue. Subject to the terms and conditions of this Agreement and in reliance upon the representations and warranties of the Borrower and the General Partner herein set forth, the Issuing Bank hereby agrees to issue for the account of Borrower, one or more Facility Letters of Credit in accordance with this Article III, and to renew, extend, increase, decrease, or otherwise modify each Facility Letter of Credit (“Modify”, and each such action a “Modification”) from time to time during the period commencing on the date hereof and ending on the Business Day prior to the Facility Termination Date. Any Lender shall have the right to decline to be the Issuing Bank for a Facility Letter of Credit provided that if no other Lender agrees to be the Issuing Bank then Administrative Agent shall agree to do so.

3.2. Types and Amounts. The Issuing Bank shall not have any obligation to:

(i) issue or Modify any Facility Letter of Credit if the aggregate maximum amount then available for drawing under Letters of Credit issued by such Issuing Bank, after giving effect to the Facility Letter of Credit or Modification requested hereunder shall exceed any limit imposed by law or regulation upon such Issuing Bank;

(ii) issue or Modify any Facility Letter of Credit if, after giving effect thereto, the Facility Letter of Credit Obligations would exceed $40,000,000 or the Allocated Facility Amount would exceed the Aggregate Commitment;

(iii) issue any Facility Letter of Credit having an expiration date, or containing automatic extension provisions to extend such date, to a date which is after the Facility Termination Date; or

(iv) issue any Facility Letter of Credit having an expiration date, or containing automatic extension provisions to extend such date, to a date which is more than fifteen (15) months after the date of its issuance.

3.3. Conditions. In addition to being subject to the satisfaction of the conditions contained in Section 5.2 hereof, the obligation of the Issuing Bank to issue any Facility Letter of Credit is subject to the satisfaction in full of the following conditions:

(i) the Borrower shall have delivered to the Issuing Bank at such times and in such manner as the Issuing Bank may reasonably prescribe such documents and materials as may be reasonably required pursuant to the terms of the proposed Facility Letter of Credit (it being understood that if any inconsistency exists between such documents and the Loan Documents, the terms of the Loan Documents shall control) and the proposed Facility Letter of Credit shall be reasonably satisfactory to the Issuing Bank as to form and content;

(ii) as of the date of issuance, no order, judgment or decree of any court, arbitrator or governmental authority shall purport by its terms to enjoin or restrain the Issuing Bank from issuing the requested Facility Letter of Credit and no law, rule or regulation applicable to the Issuing Bank and no request or directive (whether or not having the force of law) from any governmental authority with jurisdiction over the Issuing Bank shall prohibit or request that the Issuing Bank refrain from the issuance of Letters of Credit generally or the issuance of the requested Facility Letter or Credit in particular; and

(iii) there shall not exist any Default or Unmatured Default.

3.4. Procedure for Issuance of Facility Letters of Credit.

(a) Borrower shall give the Issuing Bank and the Administrative Agent at least five (5) Business Days’ prior written notice of any requested issuance of a Facility Letter of Credit under this Agreement (a “Letter of Credit Request”) (except that, in lieu of such written notice, the Borrower may give the Issuing Bank and the Administrative Agent telephonic notice of such request if confirmed in writing by delivery to the Issuing Bank and the Administrative Agent (i) immediately (A) of a telecopy of the written notice required hereunder which has been signed by an authorized officer, or (B) of a telex containing all information required to be contained in such written notice and (ii) promptly (but in no event later than the requested date of issuance) of the written notice required hereunder containing the original signature of an authorized officer); such notice shall specify:

(1) the stated amount of the Facility Letter of Credit requested (which stated amount shall not be less than $50,000);

(2) the effective date (which day shall be a Business Day) of issuance of such requested Facility Letter of Credit (the “Issuance Date”);

(3) the date on which such requested Facility Letter of Credit is to expire (which date shall be a Business Day and shall in no event be later than the earlier of fifteen months after the Issuance Date and the Facility Termination Date):

(4) the purpose for which such Facility Letter of Credit is to be issued; and

(5) the Person for whose benefit the requested Facility Letter of Credit is to be issued.

At the time such request is made, the Borrower shall also provide the Administrative Agent and the Issuing Bank with a copy of the form of the Facility Letter of Credit that the Borrower is requesting be issued, which shall be subject to the approval of the Issuing Bank and Administrative Agent. Such notice, to be effective, must be received by such Issuing Bank and the Administrative Agent not later than 2:00 p.m. (Chicago time) on the last Business Day on which notice can be given under this Section 3.4(a). Administrative Agent shall promptly give a copy of the Letter of Credit Request to the other Lenders.

(b) Subject to the terms and conditions of this Article III and provided that the applicable conditions set forth in Section 4.2 hereof have been satisfied, such Issuing Bank shall, on the Issuance Date, issue a Facility Letter of Credit on behalf of the Borrower in accordance with the Letter of Credit Request and the Issuing Bank’s usual and customary business practices (including the execution of a letter of credit application on the Issuing Bank’s standard

forms) unless the Issuing Bank has actually received (i) written notice from the Borrower specifically revoking the Letter of Credit Request with respect to such Facility Letter of Credit, (ii) written notice from a Lender, which complies with the provisions of Section 3.11(a), or (iii) written or telephonic notice from the Administrative Agent stating that the issuance of such Facility Letter of Credit would violate Section 3.2.

(c) The Issuing Bank shall give the Administrative Agent and the Borrower written or telex notice, or telephonic notice confirmed promptly thereafter in writing, of the issuance of a Facility Letter of Credit (the “Issuance Notice”) and Administrative Agent shall promptly give a copy of the Issuance Notice to the other Lenders.

(d) The Issuing Bank shall not extend or modify any Facility Letter of Credit unless the requirements of this Section 3.4 are met as though a new Facility Letter of Credit was being requested and issued.

3.5. Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility Letter of Credit of any demand for payment under such Facility Letter of Credit, the Issuing Bank shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each other Lender as to the amount to be paid by the Issuing Bank as a result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of the Issuing Bank to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility Letter of Credit in connection with such presentment shall be in conformity in all material respects with such Facility Letter of Credit. The Issuing Bank shall endeavor to exercise the same care in the issuance and administration of the Facility Letter of Credits as it does with respect to letters of credit in which no participations are granted, it being understood that in the absence of any gross negligence or willful misconduct by the Issuing Bank, each Lender shall be unconditionally and irrevocably liable without regard to the occurrence of any Default or any condition precedent whatsoever, to reimburse the Issuing Bank on demand for (i) such Lender’s Percentage of the amount of each payment made by the Issuing Bank under each Facility Letter of Credit to the extent such amount is not reimbursed by the Borrower pursuant to Section 3.6 below, plus (ii) interest on the foregoing amount to be reimbursed by such Lender, for each day from the date of the Issuing Bank’s demand for such reimbursement (or, if such demand is made after 11:00 a.m. (Chicago time) on such date, from the next succeeding Business Day) to the date on which such Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective Rate for the first three days and, thereafter, at a rate of interest equal to the rate applicable to ABR Advances.

3.6 Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to reimburse the Issuing Bank on or before the applicable LC Payment Date for any amounts to be paid by the Issuing Bank upon any drawing under any Facility Letter of Credit, without presentment, demand, protest or other formalities of any kind; provided that neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not consequential) damages suffered by the Borrower or such Lender to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the Issuing Bank in determining whether a request presented under any Facility Letter of Credit issued by it complied with the terms of such Facility Letter of Credit or (ii) the Issuing Bank’s failure to pay under any Facility Letter of Credit issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Facility Letter of Credit. All such amounts paid by the Issuing Bank and remaining unpaid by the Borrower shall bear interest, payable on demand, for each day until paid at a rate per annum equal to (x) the rate applicable to ABR Advances for such day if such day falls on or before the applicable LC Payment Date and (y) the sum of 2% plus the rate applicable to ABR Advances for such day if such day falls after such LC Payment Date. The Issuing Bank will pay to each Lender ratably in accordance with its Percentage all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility Letter of Credit issued by the Issuing Bank, but only to the extent such Lender has made payment to the Issuing Bank in respect of such Facility Letter of Credit pursuant to Section 3.5. Subject to the terms and conditions of this Agreement (including without limitation the submission of a Borrowing Notice in compliance with Section 2.10 and the satisfaction of the applicable conditions precedent set forth in Article V), the Borrower may request an Advance hereunder for the purpose of satisfying any Reimbursement Obligation.

3.7 Obligations Absolute. The Borrower’s obligations under Section 3.6 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have or have had against the Issuing Bank, any Lender or any beneficiary of a Facility Letter of Credit. The Borrower further agrees with the Issuing Bank and the Lenders that the Issuing Bank and the Lenders shall not be responsible for, and the Borrower’s Reimbursement Obligation in respect of any Facility Letter of Credit shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Facility Letter of Credit or any financing institution or other party to whom any Facility Letter of Credit may be transferred or any claims or defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Facility Letter of Credit or any such transferee. The Issuing Bank shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility Letter of Credit. The Borrower agrees that any action taken or omitted by the Issuing Bank or any Lender under or in connection with each Facility Letter of Credit and the related drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon the Borrower and shall not put the Issuing Bank or any Lender under any liability to the Borrower. Nothing in this Section 3.7 is intended to limit the right of the Borrower to make a claim against the Issuing Bank for damages as contemplated by the proviso to the first sentence of Section 3.6.

3.8 Actions of Issuing Bank. The Issuing Bank shall be entitled to rely, and shall be fully protected in relying, upon any Facility Letter of Credit, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the Issuing Bank. The Issuing Bank shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first have received such advice or concurrence of the Required Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other provision of this Article 3.8, the Issuing Bank shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holders of a participation in any Facility Letter of Credit.

3.9 Indemnification. The Borrower hereby agrees to indemnify and hold harmless each Lender, the Issuing Bank and the Administrative Agent, and their respective directors, officers, agents and employees from and against any and all claims and damages, losses, liabilities, costs or expenses which such Lender, the Issuing Bank or the Administrative Agent may incur (or which may be claimed against such Lender, the Issuing Bank or the Administrative Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility Letter of Credit or any actual or proposed use of any Facility Letter of Credit, including, without limitation, any claims, damages, losses, liabilities, costs or expenses which the Issuing Bank may incur by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to the Issuing Bank hereunder (but nothing herein contained shall affect any rights the Borrower may have against any defaulting Lender) or (ii) by reason of or on account of the Issuing Bank issuing any Facility Letter of Credit which specifies that the term “Beneficiary” included therein includes any successor by operation of law of the named Beneficiary, but which Facility Letter of Credit does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to the Issuing Bank, evidencing the appointment of such successor Beneficiary; provided that the Borrower shall not be required to indemnify any Lender, the Issuing Bank or the Administrative Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of the Issuing Bank in determining whether a request presented under any Facility Letter of Credit complied with the terms of such Facility Letter of Credit or (y) the Issuing Bank’s failure to pay under any Facility Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Facility Letter of Credit. Nothing in this Section 3.9 is intended to limit the obligations of the Borrower under any other provision of this Agreement.

3.10 Lenders’ Indemnification. Each Lender shall, ratably in accordance with its Percentage, indemnify the Issuing Bank, its affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or the Issuing Bank’s failure to pay under any Facility Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of the Facility Letter of Credit) that such indemnitees may suffer or incur in connection with this Article III or any action taken or omitted by such indemnitees hereunder.

3.11 Participation.

(a) Immediately upon issuance by the Issuing Bank of any Facility Letter of Credit or Modification in accordance with the procedures set forth in Section 3.4, each Lender shall be deemed to have irrevocably and unconditionally purchased and received from the Issuing Bank, without recourse, representation or warranty, an undivided interest and participation equal to such Lender’s Percentage in such Facility Letter of Credit (including, without limitation, all obligations of the Borrower with respect thereto) and any security therefor or guaranty pertaining thereto; provided that a Letter of Credit issued by the Issuing Bank shall not be deemed to be a Facility Letter of Credit for purposes of this Section 3.11 if the Issuing Bank shall have received written notice from any Lender on or before the Business Day prior to the date of its issuance of such Letter of Credit that one or more of the conditions contained in Section 5.2 is not then satisfied, and in the event the Issuing Bank receives such a notice it shall have no further obligation to issue any Facility Letter of Credit until such notice is withdrawn by that Lender or the Issuing Bank receives a notice from the Administrative Agent that such condition has been effectively waived in accordance with the provisions of this Agreement. Each Lender’s obligation to make further Loans to the Borrower (other than any payments such Lender is required to make under subparagraph (b) below) or issue any letters of credit on behalf of Borrower shall be reduced by such Lender’s pro rata share of each Facility Letter of Credit outstanding.

(b) Whenever the Issuing Bank receives a payment on account of a Reimbursement Obligation, including any interest thereon, the Issuing Bank shall promptly pay to the Administrative Agent and the Administrative Agent shall promptly pay to each Lender which has funded its participating interest therein, in immediately available funds, an amount equal to such Lender’s Percentage thereof.

(c) Upon the request of the Administrative Agent or any Lender, an Issuing Bank shall furnish to such Administrative Agent or Lender copies of any Facility Letter of Credit to which that Issuing Bank is party and such other documentation as may reasonably be requested by the Administrative Agent or Lender.

(d) The obligations of a Lender to make payments to the Administrative Agent for the account of each Issuing Bank with respect to a Facility Letter of Credit shall be absolute, unconditional and irrevocable, not subject to any counterclaim, set–off, qualification or exception whatsoever other than a failure of any such Issuing Bank to comply with the terms of this Agreement relating to the issuance of such Facility Letter of Credit and shall be made in accordance with the terms and conditions of this Agreement under all circumstances.

3.12 Compensation for Facility Letters of Credit.

(a) The Borrower shall pay to the Administrative Agent, for the ratable account of the Lenders, based upon the Lenders’ respective Percentages, a per annum fee (the “Facility Letter of Credit Fee”) with respect to each Facility Letter of Credit that is equal to the LIBOR Applicable Margin in effect from time to time. The Facility Letter of Credit Fee relating to any Facility Letter of Credit shall be due and payable in arrears in equal installments on each Payment Date and, to the extent any such fees are then due and unpaid, on the Facility Termination Date. The Administrative Agent shall promptly remit such Facility Letter of Credit Fees, when paid, to the other Lenders in accordance with their Percentages thereof.

(b) The Issuing Bank also shall have the right to receive solely for its own account an issuance fee of 0.15% of the face amount of each Facility Letter of Credit, payable by the Borrower on the Issuance Date for each such Facility Letter of Credit. The Issuing Bank shall also be entitled to receive its reasonable out-of-pocket costs and the Issuing Bank’s standard charges of issuing, amending and servicing Facility Letters of Credit and processing draws thereunder.

(c) Letter of Credit Collateral Account. The Borrower hereby agrees that it will, until the Facility Termination Date, maintain a special collateral account (the “Letter of Credit Collateral Account”) at the Administrative Agent's office at the address specified pursuant to Article XIV, in the name of the Borrower but under the sole dominion and control of the Administrative Agent, for the benefit of the Lenders, and in which the Borrower shall have no interest other than as set forth in Section 9.1. Such Letter of Credit Collateral Account shall be funded to the extent required by Section 9.1. In addition to the foregoing, the Borrower hereby grants to the Administrative Agent, for the benefit of the Lenders, a properly perfected security interest in and to the Letter of Credit Collateral Account, any funds that may hereafter be on deposit in such account and the proceeds thereof.

If, on or after the date of this Agreement, the adoption of any law or any governmental or quasi–governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in the interpretation or administration thereof by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending Installation or the Issuing Bank with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

(a) subjects any Lender or any applicable Lending Installation or the Issuing Bank to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender or the Issuing Bank in respect of its LIBOR Loans, Facility Letters of Credit or participations therein, or

(b) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation or the Issuing Bank (other than reserves and assessments taken into account in determining the interest rate applicable to LIBOR Advances), or

(c) imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation or the Issuing Bank of making, funding or maintaining its LIBOR Loans, or of issuing or participating in Facility Letters of Credit, or reduces any amount receivable by any Lender or any applicable Lending Installation or the Issuing Bank in connection with its LIBOR Loans, Facility Letters of Credit or participations therein, or requires any Lender or any applicable Lending Installation or the Issuing Bank to make any payment calculated by reference to the amount of LIBOR Loans, Facility Letters of Credit or participations therein held or interest or LC Fees received by it, by an amount deemed material by such Lender or the Issuing Bank as the case may be, and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation or the Issuing Bank, as the case may be, of making or maintaining its LIBOR Loans or Commitment or of issuing or participating in Facility Letters of Credit or to reduce the return received by such Lender or applicable Lending Installation or the Issuing Bank, as the case may be, in connection with such LIBOR Loans, Commitment, Facility Letters of Credit or participations therein, then, within 15 days of demand by such Lender or the Issuing Bank, as the case may be, the Borrower shall pay such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such increased cost or reduction in amount received.

4.2 Changes in Capital Adequacy Regulations.

If a Lender or the Issuing Bank in good faith determines the amount of capital required or expected to be maintained by such Lender or the Issuing Bank, any Lending Installation of such Lender or the Issuing Bank or any corporation controlling such Lender or the Issuing Bank is increased as a result of a Change (as hereinafter defined), then, within 15

days of demand by such Lender or the Issuing Bank, the Borrower shall pay such Lender or the Issuing Bank the amount necessary to compensate for any shortfall in the rate of return on the portion of such increased capital which such Lender or the Issuing Bank in good faith determines is attributable to this Agreement, its Outstanding Credit Exposure or its obligation to make Loans and issue or participate in Facility Letters of Credit, as the case may be, hereunder (after taking into account such Lender’s or the Issuing Bank’s policies as to capital adequacy). “Change” means (i) any change after the date of this Agreement in the Risk–Based Capital Guidelines (as hereinafter defined) or (ii) any adoption of or change in any other law, governmental or quasi–governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the date of this Agreement which affects the amount of capital required or expected to be maintained by any Lender or the Issuing Bank or any Lending Installation or any corporation controlling any Lender or the Issuing Bank. “Risk–Based Capital Guidelines” means (i) the risk–based capital guidelines in effect in the United States on the date of this Agreement, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basel Committee on Banking Regulation and Supervisory Practices Entitled “International Convergence of Capital Measurements and Capital Standards,” including transition rules, and any amendments to such regulations adopted prior to the date of this Agreement.

4.3 Availability of Types of Advances.

If any Lender in good faith determines that maintenance of any of its LIBOR Loans at a suitable Lending Installation would violate any applicable law, rule, regulation or directive, whether or not having the force of law, the Administrative Agent shall suspend the availability of the affected Type of Advance and require any LIBOR Advances of the affected Type to be repaid; or if the Required Lenders in good faith determine that (i) deposits of a type or maturity appropriate to match fund LIBOR Advances are not available, or (ii) an interest rate applicable to a Type of Advance does not accurately reflect the cost of making a LIBOR Advance of such Type, then, the Administrative Agent shall suspend the availability of the affected Type of Advance with respect to any LIBOR Advances made after the date of any such determination. If the Borrower is required to so repay a LIBOR Advance, the Borrower may concurrently with such repayment borrow from the Lenders, in the amount of such repayment, a Loan bearing interest at the Alternate Base Rate.

4.4 Funding Indemnification.

If any payment of a ratable LIBOR Advance or a Competitive Bid Loan occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a ratable LIBOR Advance or a Competitive Bid Loan is not made on the date specified by the Borrower for any reason other than default by the Lenders or as a result of unavailability pursuant to Section 4.3, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain the ratable LIBOR Advance or Competitive Bid Loan, as the case may be, and shall pay all such losses or costs within fifteen (15) days after written demand therefor. Nothing in this Section 4.4 shall authorize the prepayment of a Competitive Bid Loan prior to the end of the applicable Interest Period.

4.5 Taxes.

(i) All payments by the Borrower to or for the account of any Lender or the Administrative Agent hereunder or under any Note shall be made free and clear of and without deduction for any and all Taxes. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Lender or the Administrative Agent, (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.5) such Lender or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower shall make such deductions, (c) the Borrower shall pay the full amount deducted to the relevant authority in accordance with applicable law and (d) the Borrower shall furnish to the Administrative Agent the original copy of a receipt evidencing payment thereof within 30 days after such payment is made.

(ii) In addition, the Borrower hereby agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note (“Other Taxes”).

(iii) The Borrower hereby agrees to indemnify the Administrative Agent and each Lender for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed on amounts payable under this Section 4.5) paid by the Administrative Agent or such Lender and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Payments due under this indemnification shall be made within 30 days of the date the Administrative Agent or such Lender makes demand therefor pursuant to Section 4.6.

(iv) Each Lender that is not incorporated under the laws of the United States of America or a state thereof (each a “Non-U.S. Lender”) agrees that it will, not more than ten Business Days after the date of this Agreement, (i) deliver to each of the Borrower and the Administrative Agent two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either case that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, and (ii) deliver to each of the Borrower and the Administrative Agent a United States Internal Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to an exemption from United States backup withholding tax. Each Non-U.S. Lender further undertakes to deliver to each of the Borrower and the Administrative Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Borrower or the Administrative Agent. All forms or amendments described in the preceding sentence shall certify that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and such Lender advises the Borrower and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

(v) For any period during which a Non-U.S. Lender has failed to provide the Borrower with an appropriate form pursuant to clause (iv), above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which a form originally was required to be provided), such Non-U.S. Lender shall not be entitled to indemnification under this Section 4.5 with respect to Taxes imposed by the United States.

(vi) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Note pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate following receipt of such documentation.

(vii) If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly completed, because such Lender failed to notify the Administrative Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Administrative Agent under this subsection, together with all costs and expenses related thereto (including attorneys fees and time charges of attorneys for the Administrative Agent, which attorneys may be employees of the Administrative Agent). The obligations of the Lenders under this Section 4.5(vii) shall survive the payment of the Obligations and termination of this Agreement.

4.6 Lender Statements; Survival of Indemnity.

To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its LIBOR Loans to reduce any liability of the Borrower to such Lender under Sections 4.1, 4.2 and 4.5 or to avoid the unavailability of Advances under Section 4.3, so long as such designation does not reduce such Lender’s income or increase such Lender’s liabilities. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Administrative Agent) as to the amount due, if any, under Section 4.1, 4.2, 4.4 or 4.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a LIBOR Loan shall be calculated as though each Lender funded its LIBOR Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the LIBOR Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall be payable on demand after receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 4.1, 4.2, 4.4 and 4.5 shall survive payment of the Obligations and termination of this Agreement.

4.7 Replacement of Lenders under Certain Circumstances.

The Borrower shall be permitted to replace any Lender which (a) is not capable of receiving payments without any deduction or withholding of United States federal income tax pursuant to Section 4.5, or (b) cannot maintain its LIBOR Loans at a suitable Lending Installation pursuant to Section 4.6, with a replacement bank or other financial institution; provided that (i) such replacement does not conflict with any applicable legal or regulatory requirements affecting the remaining Lenders, (ii) no Default or (after notice thereof to Borrower) no Unmatured Default shall have occurred and be continuing at the time of such replacement, (iii) the Borrower shall repay (or the replacement bank or institution shall purchase, at par) all Loans and other amounts owing to such replaced Lender prior to the date of replacement, (iv) the Borrower shall be liable to such replaced Lender under Sections 4.4 and 4.6 if any LIBOR Loan owing to such replaced Lender shall be prepaid (or purchased) other than on the last day of the Interest Period relating thereto, (v) the replacement bank or institution, if not already a Lender, and the terms and conditions of such replacement, shall be reasonably satisfactory to the Administrative Agent, (vi) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 13.3 (provided that the Borrower shall be obligated to pay the processing fee referred to therein), (vii) until such time as such replacement shall be consummated, the Borrower shall continue to pay all amounts payable hereunder without setoff, deduction, counterclaim or withholding and (viii) any such replacement shall not be deemed to be a waiver of any rights which the Borrower, the Administrative Agent or any other Lender shall have against the replaced Lender.

ARTICLE IX

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

9.1 Acceleration. If any Default described in Section 8.7 or 8.8 occurs with respect to the Borrower, the obligations of the Lenders to make Loans and of the Issuing Bank to issue Facility Letters of Credit hereunder shall automatically terminate and the Obligations shall immediately become due and payable without any election or action on the part of the Administrative Agent or any Lender. If any other Default occurs, the Administrative Agent may and will if directed by the Required Lenders, terminate or suspend the obligations of the Lenders to make Loans hereunder and to issue Facility Letters of Credit, or declare the Obligations to be due and payable, or both, whereupon the Obligations shall become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which the Borrower hereby expressly waives.

In addition to the foregoing, following the occurrence of a Default and so long as any Facility Letter of Credit has not been fully drawn and has not been cancelled or expired by its terms, upon demand by the Administrative Agent (which Administrative Agent agrees to make if requested to by the Required Lenders) the Borrower shall deposit in the Letter of Credit Collateral Account cash in an amount equal to the aggregate undrawn face amount of all outstanding Facility Letters of Credit and all fees and other amounts due or which may become due with respect thereto. The Borrower shall have no control over funds in the Letter of Credit Collateral Account, which funds will be invested by the Administrative Agent from time to time at its discretion in certificates of deposit of First Chicago having a maturity not exceeding 30

days. Such funds shall be promptly applied by the Administrative Agent to reimburse any Issuing Bank for drafts drawn from time to time under the Facility Letters of Credit. Such funds, if any, remaining in the Letter of Credit Collateral Account following the payment of all Obligations in full shall, unless Administrative Agent is otherwise directed by a court of competent jurisdiction, be promptly paid over to the Borrower.

If, within thirty (30) days after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Loans hereunder or to issue Facility Letters of Credit as a result of any Default (other than any Default as described in Section 8.7 or 8.8 with respect to the Borrower) and before any judgment or decree for the payment of the Obligations shall have been obtained or entered, the Required Lenders (in their sole discretion) shall so direct, the Administrative Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination.

9.2 Amendments. Subject to the provisions of this Article IX, the Required Lenders (or the Administrative Agent with the consent in writing of the Required Lenders), the Borrower and the General Partner may enter into agreements supplemental hereto for the purpose of adding or modifying any provisions to the Loan Documents or changing in any manner the rights of the Lenders or the Borrower hereunder or waiving any Default hereunder; provided, however, that no such supplemental agreement shall, without the consent of Administrative Agent and Syndication Agent, waive any Default under, or modify or amend Sections 7.20(iii) or (v); and provided, further, however, that no such supplemental agreement shall, without the consent of all Lenders:

(i) Extend the Facility Termination Date or forgive all or any portion of the principal amount of any Loan or accrued interest thereon or the Facility Fee, reduce the Applicable Margins on the underlying interest rate options or otherwise modify or add to such interest rate options, or extend the time of payment of any of the Obligations.

(ii) Release the General Partner from the Guaranty, or materially modify the Guaranty or waive a material provision of the Guaranty.

(iii) Reduce the percentage specified in the definition of Required Lenders.

(iv) Increase the amount of the Aggregate Commitment to an amount in excess of $600,000,000.

(v) Permit the Borrower to assign or allow another Person to assume its rights under this Agreement.

(vi) Amend this Section 9.2.

(vii) Amend Section 2.23 such that payments that are now required to be applied in accordance with the Funded Percentages of the Lenders shall be applied in any other manner.

No amendment of any provision of this Agreement relating to the Administrative Agent shall be effective without the written consent of the Administrative Agent, and no amendment increasing the Commitment of any Lender shall be effective without the written consent of such Lender. The approval of the Required Lenders shall not be required to increase the Aggregate Commitment in accordance with Section 2.1.

Notwithstanding the foregoing: (1) no amendment, waiver, or consent shall, unless in writing and signed by the Designating Lender on behalf of its respective Designated Lender affected thereby, (a) subject such Designated Lender to any additional obligations, (b) reduce the principal of, interest on, or the amounts due with respect to, the Competitive Bid Loan Note made payable to such Designated Lender, (c) postpone any date fixed for any payment of principal of, or interest on, or other amounts due with respect to, the Competitive Bid Note made payable to such Designated Lender, or (d) amend the definition of Required Lenders hereunder in a manner which adversely affects the rights of such Designated Lender.

9.3 Preservation of Rights. No delay or omission of the Lenders or the Administrative Agent to exercise any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Loan notwithstanding the existence of a Default or the inability of the Borrower to satisfy the conditions precedent to such Loan shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed by the Lenders required pursuant to Section 9.2, and then only to the extent in such writing specifically set forth. All remedies contained in the Loan Documents or by law afforded shall be cumulative and all shall be available to the Administrative Agent and the Lenders until the Obligations have been paid in full.

The respective obligations of the Lenders hereunder are several and not joint and no Lender shall be the partner or agent of any other (except to the extent to which the Administrative Agent is authorized to act as such). The failure of any Lender to perform any of its obligations hereunder shall not relieve any other Lender from any of its obligations hereunder. This Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and assigns.

10.7 Expenses; Indemnification. The Borrower shall reimburse the Indemnified Parties on demand for any costs, internal charges and reasonable out–of–pocket expenses (including, without limitation, all reasonable fees for consultants and reasonable fees and expenses for attorneys for the Indemnified Parties, which attorneys may be employees of the Indemnified Parties) paid or incurred by the Indemnified Parties (whether in their capacity as arranger, or, in the case of Bank One, NA in its capacity as Administrative Agent) in connection with the preparation, negotiation, execution, delivery, review, amendment, modification, and administration of the Loan Documents. The Borrower also agrees to reimburse the Indemnified Parties and the Lenders for any costs, internal charges and reasonable out–of–pocket expenses (including, without limitation, all reasonable fees and expenses for attorneys for the Indemnified Parties and the Lenders, which attorneys may be employees of the Indemnified Parties or the Lenders) paid or incurred by the Indemnified Parties

(whether in their capacity as arranger, or, in the case of Bank One, NA, in its capacity as Administrative Agent) or any Lender in connection with the collection and enforcement of the Loan Documents (including, without limitation, any workout). The Borrower further agrees to indemnify the Indemnified Parties and each Lender and their directors, officers and employees against all losses, claims, damages, penalties, judgments, liabilities and reasonable expenses (including, without limitation, all expenses of litigation or preparation therefor whether or not such entity is a party thereto) which any of them may pay or incur arising out of or relating to this Agreement, the other Loan Documents, the Projects, the transactions contemplated hereby or the direct or indirect application or proposed application of the proceeds of any Loan hereunder. The obligations of the Borrower under this Section 10.7 shall survive the termination of this Agreement.

10.8 Numbers of Documents. All statements, notices, closing documents, and requests hereunder shall be furnished to the Administrative Agent with sufficient counterparts so that the Administrative Agent may furnish one to each of the Lenders.

10.9 Accounting. Except as provided to the contrary herein, all accounting terms used herein shall be interpreted and all accounting determinations hereunder shall be made in accordance with GAAP.

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

10.11 Nonliability of Lenders. The relationship between the General Partner and the Borrower, on the one hand, and the Lenders, the Arranger and the Administrative Agent, on the other, shall be solely that of borrower and lender. Neither the Administrative Agent, the Arranger nor any Lender shall have any fiduciary responsibilities to the General Partner and the Borrower. Neither the Administrative Agent, the Arranger nor any Lender undertakes any responsibility to the Borrower to review or inform the Borrower of any matter in connection with any phase of the Borrower’s business or operations.

10.12 Publicity. The Lenders shall have the right to do a tombstone publicizing the transaction contemplated hereby without the consent of the Borrower or General Partner.

10.13 Choice of Law. The loan documents (other than those containing a contrary express choice of law provision) shall be construed in accordance with the internal laws (and not the law of conflicts) of the state of illinois, but giving effect to federal laws applicable to national banks.

10.14 Consent to Jurisdiction. The general partner and the borrower each hereby irrevocably submits to the non–exclusive jurisdiction of any united states federal or illinois state court sitting in chicago in any action or proceeding arising out of or relating to any of the loan documents and the general partner and the borrower each hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in any such court and irrevocably waives any objection it may now or hereafter have as to the venue of any such suit, action or proceeding brought in such a court or that such court is an inconvenient forum. Nothing herein shall limit the right of the administrative agent or any lender to bring proceedings against the general partner or the borrower in the courts of any other jurisdiction. Any judicial proceeding by the general partner or the borrower against the administrative agent or any lender or any affiliate of the administrative agent or any lender involving, directly or indirectly, any matter in any way arising out of, related to, or connected with any loan document shall be brought only in a court in chicago, illinois.

10.15 Waiver of Jury Trial. The general partner, the borrower, the administrative agent and each lender hereby waive trial by jury in any judicial proceeding involving, directly or indirectly, any matter (whether sounding in tort, contract or otherwise) in any way arising out of, related to, or connected with any loan document or the relationship established thereunder.

10.16 Agent Responsibilities. Borrower, the Administrative Agent and each Lender acknowledges and agrees that the obligations of the Syndication Agent, the Documentation Agent, the Managing Agents, and the Co-Agents (collectively, the “Other Agents”) hereunder shall be limited to those obligations that are expressly set forth herein, if any, or in any other written agreement with such parties, and the Other Agents shall not be required to take any other action or assume any liability except as may be required in their capacity as a Lender hereunder. Borrower, the Administrative Agent and each Lender agrees that the indemnifications set forth herein for the benefit of the Administrative Agent shall also run to the benefit of each Other Agent to the extent such Other Agent incurs any loss, cost or damage arising from its agency capacity hereunder.

ARTICLE XI

THE ADMINISTRATIVE AGENT AND AGREEMENTS AMONG LENDERS

11.1 Appointment; Nature of Relationship. Bank One, NA is hereby appointed by each of the Lenders as its contractual representative (herein referred to as the “Agent”) hereunder and under each other Loan Document, and each of the Lenders irrevocably authorizes the Agent to act as the contractual representative of such Lender with the rights and duties expressly set forth herein and in the other Loan Documents. The Agent agrees to act as such contractual representative upon the express conditions contained in this Article XI. Notwithstanding the use of the defined term “Agent,” it is expressly understood and agreed that the Agent shall not have any fiduciary responsibilities to any Lender by reason of this Agreement or any other Loan Document and that the Agent is merely acting as the contractual representative of the Lenders with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the Lenders’ contractual representative, the Agent (i) does not hereby assume any fiduciary duties to any of the Lenders, (ii) is a “representative” of the Lenders within the meaning of Section 9-105 of the Uniform Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Loan Documents. Each of the Lenders hereby agrees to assert with respect to the Loan Documents and administration of the Loan, no claim against the Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby waives.

11.2 Powers. The Administrative Agent shall have and may exercise such powers under the Loan Documents as are specifically delegated to the Administrative Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Administrative Agent shall have no implied duties to the Lenders, or any obligation to the Lenders to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Administrative Agent.

11.3 General Immunity. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender for any action lawfully taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except for its or their own gross negligence or willful misconduct.

11.4 No Responsibility for Loans, Recitals, etc. Except where the failure to do so constitutes gross negligence or wilful misconduct, neither the Administrative Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (i) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (ii) the performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including, without limitation, any agreement by an obligor to furnish information directly to each Lender; (iii) the satisfaction of any condition specified in Article V, except receipt of items required to be delivered to the Administrative Agent; (iv) the validity, effectiveness or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith; or (v) the value, sufficiency, creation, perfection or priority of any interest in any collateral security. The Administrative Agent shall have no duty to disclose to the Lenders information that is not required to be furnished by the Borrower to the Administrative Agent at such time, but is voluntarily furnished by the Borrower to the Administrative Agent (either in its capacity as Administrative Agent or in its individual capacity).

11.5 Action on Instructions of Lenders. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Document in accordance with written instructions signed by the Required Lenders or, where consent of all Lenders is required, all Lenders, and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders and on all holders of Notes. The Administrative Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its reasonable satisfaction by the Lenders pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

11.6 Employment of Agents and Counsel. The Administrative Agent may execute any of its duties as Administrative Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys–in–fact and so long as it exercises reasonable care in the selection of such parties, the Administrative Agent shall not be answerable to the Lenders, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such parties. The Administrative Agent shall be entitled to advice of counsel concerning all matters pertaining to the agency hereby created and its duties hereunder and under any other Loan Document.

11.7 Reliance on Documents; Coursel. The Administrative Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Administrative Agent, which counsel may be employees of the Administrative Agent.

11.8 Administrative Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Administrative Agent ratably in proportion to their respective Commitments (i) for any reasonable amounts not reimbursed by the Borrower or Guarantor for which the Administrative Agent is entitled to reimbursement by the Borrower under the Loan Documents including reasonable out-of-pocket expenses in connection with the preparation, execution, delivery of the Loan Documents, (ii) for any other reasonable out-of-pocket expenses incurred by the Administrative Agent on behalf of the Lenders, in connection with the administration and enforcement of the Loan Documents and (iii) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby, or the enforcement of any of the terms thereof or of any such other documents, provided that no Lender shall be liable for (i) any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the Administrative Agent, or (ii) any costs or expenses of the Administrative Agent’s in-house legal staff and personnel. The obligations of the Lenders under this Section 11.8 shall survive payment of the Obligations and termination of this Agreement, and shall not be reduced by the designation of a Designated Lender to fund Competitive Bid Loans on behalf of a Lender, provided that each Designated Lender shall be jointly and severally liable with the Designating Lender for the Designating Lender’s Share (as hereinafter determined) of the amounts due from such Designating Lender. The Designated Lender’s Share of amounts due shall be equal to such amount due multiplied by a fraction whose numerator is the amount funded by the Designated Lender (but in no event more than the amount of Designating Lender’s Commitment) and whose denominator is the amount of the Designating Lender’s Commitment.

11.9 Rights as a Lender. In the event the Administrative Agent is a Lender, the Administrative Agent shall have the same rights and powers and the same duties and obligations hereunder and under any other Loan Document as any Lender and may exercise the same as though it were not the Administrative Agent, and the term “Lender” or “Lenders” shall, at any time when the Administrative Agent is a Lender, unless the context otherwise indicates, include the Administrative Agent in its individual capacity. The Administrative Agent may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with the Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is not restricted hereby from engaging with any other Person.

11.10 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on the financial statements prepared by the Borrower and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents.

11.11 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, and the Administrative Agent shall be deemed to have automatically resigned if it is no longer a Lender, such resignation in either case to be effective upon the appointment of a successor Administrative Agent or, if no successor Administrative Agent has been appointed, forty-five days after the retiring Administrative Agent gives notice of its intention to resign or ceases to be a Lender, as the case may be. The Administrative Agent may be removed at any time with good cause by written notice received by the Administrative Agent from the Required Lenders, such removal to be effective on the date specified by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint, on behalf of the Borrower and the Lenders, a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders within thirty days after the resigning Administrative Agent’s giving notice of its intention to resign, then the resigning Administrative Agent may appoint, on behalf of the Borrower and the Lenders, a successor Administrative Agent. If the Administrative Agent has resigned or been removed and no successor Administrative Agent has been appointed within 45 days, the Lenders shall perform all the duties of the Administrative Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. No successor Administrative Agent shall be deemed to be appointed hereunder until such successor Administrative Agent has accepted the appointment. Any such successor Administrative Agent shall be a commercial bank (or a subsidiary thereof) having capital and retained earnings of at least $500,000,000, except that if the successor Administrative Agent is a subsidiary of a bank, such capital and retained earnings requirement shall apply only to the parent bank. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Administrative Agent. Upon the effectiveness of the resignation or removal of the Administrative Agent, the resigning or removed Administrative Agent and the successor Administrative Agent shall pro rate any agency fees, and the resigning or removed Administrative Agent shall be discharged from its duties and obligations thereafter arising hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of an Administrative Agent, the provisions of this Article XI shall continue in effect for the benefit of such Administrative Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent hereunder and under the other Loan Documents.

11.12 Notice of Defaults. If a Lender becomes aware of a Default or Unmatured Default, such Lender shall notify the Administrative Agent of such fact provided that the failure to give such notice shall not create liability on the part of a Lender. Upon receipt of such notice that a Default or Unmatured Default has occurred, the Administrative Agent shall notify each of the Lenders of such fact.

11.13 Requests for Approval. If the Administrative Agent requests in writing the consent or approval of a Lender, such Lender shall respond and either approve or disapprove definitively in writing to the Administrative Agent within ten Business Days (or sooner if such notice specifies a shorter period for responses based on Administrative Agent’s good faith determination that circumstances exist warranting its request for an earlier response) after such written request from the Administrative Agent. If the Lender does not so respond, that Lender shall be deemed to have approved the request.

11.14 Copies of Documents. Within fifteen Business Days after a request by a Lender to the Administrative Agent for documents furnished to the Administrative Agent by the Borrower, the Administrative Agent shall provide copies of such documents to such Lender.

11.15 Defaulting Lenders. At such time as a Lender becomes a Defaulting Lender, such Defaulting Lender’s right to vote on matters which are subject to the consent or approval of the Required Lenders, each affected Lender or all Lenders shall be immediately suspended until such time as the Lender is no longer a Defaulting Lender, except that the amount of the Commitment of the Defaulting Lender may not be changed without its consent. If a Defaulting Lender has failed to fund its pro rata share of any Advance and until such time as such Defaulting Lender subsequently funds its pro rata share of such Advance, all Obligations owing to such Defaulting Lender hereunder shall be subordinated in right of payment, as provided in the following sentence, to the prior payment in full of all principal of, interest on and fees relating to the Loans funded by the other Lenders in connection with any such Advance in which the Defaulting Lender has not funded its pro rata share (such principal, interest and fees being referred to as “Senior Loans” for the purposes of this section). All amounts paid by the Borrower or the Guarantor and otherwise due to be applied to the Obligations owing to such Defaulting Lender pursuant to the terms hereof shall be distributed by the Administrative Agent to the other Lenders in accordance with their respective pro rata shares (recalculated for the purposes hereof to exclude the Defaulting Lender) until all Senior Loans have been paid in full. After the Senior Loans have been paid in full equitable adjustments will be made in connection with future payments by the Borrower to the extent a portion of the Senior Loans had been repaid with amounts that otherwise would have been distributed to a Defaulting Lender but for the operation of this Section 11.15. This provision governs only the relationship among the Administrative Agent, each Defaulting Lender and the other Lenders; nothing hereunder shall limit the obligation of the Borrower to repay all Loans in accordance with the terms of this Agreement. The provisions of this section shall apply and be effective regardless of whether a Default occurs and is continuing, and notwithstanding (i) any other provision of this Agreement to the contrary, (ii) any instruction of the Borrower as to its desired application of payments or (iii) the suspension of such Defaulting Lender’s right to vote on matters which are subject to the consent or approval of the Required Lenders or all Lenders.

ARTICLE XII

SETOFF; RATABLE PAYMENTS

12.1 Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if the Borrower becomes insolvent, however evidenced, or any Default or Unmatured Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender to or for the credit or account of the Borrower may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part hereof, shall then be due.

12.2 Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Loans (other than payments received pursuant to Sections 4.1, 4.2 or 4.4) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Loans held by the other Lenders so that after such purchase each Lender will hold its ratable proportion of Loans. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their Loans. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XIII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

13.1 Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower and the Lenders and their respective successors and assigns, except that (i) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents and (ii) any assignment by any Lender must be made in compliance with Section 13.3. Notwithstanding clause (ii) of this Section 13.1, any Lender may at any time, without the consent of the Borrower or the Administrative Agent, assign all or any portion of its rights under this Agreement and its Notes to a Federal Reserve Bank; provided, however, that no such assignment shall release the

transferor Lender from its obligations hereunder. The Administrative Agent may treat the payee of any Note as the owner thereof for all purposes hereof unless and until such payee complies with Section 13.3 in the case of an assignment thereof or, in the case of any other transfer, a written notice of the transfer is filed with the Administrative Agent. Any assignee or transferee of a Note agrees by acceptance thereof to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the holder of any Note, shall be conclusive and binding on any subsequent holder, transferee or assignee of such Note or of any Note or Notes issued in exchange therefor.

13.2 Participations.

13.2.1 Permitted Participants; Effect. Any Lender, in the ordinary course of its business and in accordance with applicable law, at any time, may sell participating interests in any Loan owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. Any Person to whom such a participating interest is sold is a “Participant”. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the holder of any such Note for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents.

13.2.2 Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Loan or Commitment in which such Participant has an interest which forgives principal, interest or fees or reduces the interest rate or fees payable with respect to any such Loan or Commitment or postpones any date fixed for any regularly–scheduled payment of principal of, or interest or fees on, any such Loan or Commitment or releases any guarantor of any such Loan or releases any substantial portion of collateral, if any, securing such Loan, or changes the definition of Required Lenders.

13.2.3 Benefit of Setoff. The General Partner and the Borrower each agrees that each Participant shall be deemed to have the right of setoff provided in Section 12.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender shall retain the right of setoff provided in Section 12.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 13.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 12.2 as if each Participant were a Lender.

13.3 Assignments.

13.3.1 Permitted Assignments. Any Lender, in the ordinary course of its business and in accordance with applicable law, at any time, may assign all or any portion (greater than or equal to $5,000,000 per assignee) of its rights and obligations under the Loan Documents. Any Person to whom such rights and obligations are assigned is a “Purchaser”. Such assignment shall be substantially in the form of Exhibit H hereto or in such other form as may be agreed to by the parties thereto. The consent of the Administrative Agent shall be required prior to an assignment becoming effective with respect to a Purchaser which is not a Lender or a Lender Affiliate, except no consent shall be required if a Default exists. Such consent shall not be unreasonably withheld.

13.3.2 Effect; Effective Date. Upon (i) delivery to the Administrative Agent of a notice of assignment, substantially in the form attached as Exhibit I to Exhibit H hereto (a “Notice of Assignment”), together with any consents required by Section 13.3.1, and (ii) payment of a $3,500 fee to the Administrative Agent for processing such assignment (unless the assignment is to an affiliate of the Lender in which case no fee shall be charged), such assignment shall become effective on the effective date specified in such Notice of Assignment. The Notice of Assignment shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment and Loans under the applicable assignment agreement are “plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Borrower, the Lenders or the Administrative Agent shall be required to release the transferor Lender with respect to the percentage of the Aggregate Commitment and Loans assigned to such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant to this Section 13.3.2, the transferor Lender, the Administrative Agent and the Borrower shall make appropriate arrangements so that replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their Commitment, as adjusted pursuant to such assignment.

13.4 Designation of Lender to Make Competitive Bid Loans. Any Lender (each a “Designating Lender”) may at any time designate one or more Designated Lenders to fund Competitive Bid Loans which the Designating Lender is required to fund subject to the terms of this Section 13.4 and the provisions in Section 13.3 shall not apply to such designation. No Lender shall be entitled to make more than two such designations. The parties to each such designation shall execute and deliver to the Administrative Agent, for its acceptance, a Designation Agreement in the form of Exhibit I. Upon its receipt of an appropriately completed Designation Agreement executed by a Designating Lender and a Designee representing that it is a Designated Lender, the Administrative Agent will accept such Designation Agreement and give prompt notice thereof to the Borrower, whereupon, from and after the effective date specified in the Designation Agreement, the Designated Lender shall become a party to this Agreement with a right to make Competitive Bid Loans on behalf of its Designating Lender pursuant to Section 2.15 after the Borrower has accepted a Competitive Bid (or a portion thereof) of the Designating Lender. Each Designating Lender shall serve as the agent for the Designated Lender and shall on behalf of the Designated Lender give and receive all communications and notices and take all actions hereunder, including without limitation votes, approvals, waivers, consents and amendments under or relating to this Agreement or the other Loan Documents. Any such notice, communications, vote approval, waiver, consent or amendment shall be signed by the Designating Lender as agent for the Designated Lender and shall not be signed by the Designated Lender. The Borrower, the Administrative Agent and the Lenders may rely thereon without any requirement that the Designated Lender sign or acknowledge the same, and without any specific designation that the Designating Lender is signing in an agency capacity. The parties hereto agree not to institute or join any other person in instituting against any Designated Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding, or other proceeding under any federal or state bankruptcy or similar law, for one year and a day after the Facility Termination Date. This Section 13.4 shall survive the termination of this Agreement.

13.5 Dissemination of Information. The General Partner and the Borrower authorize each Lender to disclose any and all information in such Lender’s possession concerning the creditworthiness of the General Partner, the Borrower and their Subsidiaries to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee and any swap counterparty as prospective swap counterparty with whom a Lender has entered or is considering entering into a transaction to hedge such Lender’s credit risk in connection with this Facility.

13.6 Tax Treatment. If any interest in any Loan Document is transferred to any Transferee which is organized under the laws of any jurisdiction other than the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 2.22.

ARTICLE XIV
