From the date of this Agreement to the Termination Date, (a) each Lender severally agrees, on the terms and conditions set forth in this Agreement, to make loans (each a "Revolving Loan") to the Borrower from time to time in an amount equal to its Pro Rata Share of all Revolving Loans requested by the Borrower, (b) the Issuer agrees to issue Letters of Credit for the account of the Borrower from time to time in an aggregate amount not at any time exceeding $20,000,000 (and each Lender severally agrees to participate in each such Letter of Credit as more fully set forth in Section 2.20) and (c) the Swing Line Lender agrees to make Swing Line Loans to the Borrower from time to time in an aggregate amount not at any time exceeding $20,000,000 (and each Lender severally agrees to participate in each such Swing Line Loan as more fully set forth in Section 2.21.3); provided that the Total Outstandings shall not at any time exceed the Aggregate Commitment. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Revolving Loans at any time prior to the Termination Date.

           2.2    Types of Advances. Advances may be Floating Rate Advances or Eurodollar Advances, or a combination thereof, as selected by the Borrower in accordance with Sections 2.4 and 2.5.

           2.3    Minimum Amount of Each Advance. Each Eurodollar Advance shall be in the amount of $1,000,000 or a higher integral multiple thereof and each Floating Rate Advance shall be in the amount of $1,000,000 or a higher integral multiple of $500,000, provided that (a) any Floating Rate Advance made (in whole or in part) to repay any Reimbursement Obligations or any Swing Line Loan may be in the amount of $100,000 or an integral multiple thereof; and (b) any Floating Rate Advance may be in the amount of the unused Aggregate Commitment.

           2.4    Method of Selecting Types and Interest Periods for New Advances. The Borrower shall select the Type of Advance and, in the case of each Eurodollar Advance, the Interest Period applicable thereto from time to time. The Borrower shall give the Administrative Agent irrevocable notice (a "Borrowing Notice") not later than 11:00 a.m. on the Borrowing Date of each Floating Rate Advance and three Business Days before the Borrowing Date of each Eurodollar Advance, specifying:

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

           (ii)    the aggregate amount of such Advance,

          (iii)    the Type of Advance selected, and

          (iv)    in the case of a Eurodollar Advance, the Interest Period applicable thereto.

Each Borrowing Notice shall be in writing (or by telephone promptly confirmed in writing) substantially in the form of Exhibit A. Not later than 1:00 p.m. on the Borrowing Date for an Advance, each Lender shall make available its Pro Rata Share of such Advance in funds immediately available in Chicago to the Administrative Agent at its address specified pursuant to Article XIII. The Administrative Agent will make the funds so received from the Lenders available to the Borrower at the Administrative Agent's aforesaid address.

           2.5    Conversion and Continuation of Outstanding Advances. Floating Rate Advances shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.5 or are repaid. Each Eurodollar Advance shall continue as a Eurodollar Advance, until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Floating Rate Advance unless (x) such Advance is or was repaid or (y) the Borrower shall have given the Administrative Agent a Conversion/Continuation Notice requesting that, at the end of such Interest Period, such Advance continue as a Eurodollar Advance for the same or another Interest Period. Subject to the terms of Section 2.3, the Borrower may elect from time to time to convert all or any part of any Advance into an Advance of the other Type. The Borrower shall give the Administrative Agent irrevocable notice (a "Conversion/Continuation Notice") of each continuation or conversion of an Advance (other than an automatic continuation or conversion as provided in this Section 2.5) not later than the time specified in Section 2.4 for the making of the Type of Advance to be continued or converted into, 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;

          (iii)    in the case of conversion of an Advance, the Type of Advance to be converted into;

          (iv)   the amount of the Advance which is to be converted or continued; and

          (v)    in the case of conversion into or continuation of a Eurodollar Advance, the duration of the Interest Period applicable thereto.

            Each Conversion/Continuation Notice given by the Borrower shall constitute a representation and warranty by the Borrower that no Default or Unmatured Default exists.

           2.6         Commitment Fee; Voluntary Changes in Aggregate Commitment.

           2.6.1          The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee at a per annum rate equal to the Commitment Fee Rate on the daily unused portion of such Lender's Commitment from the date hereof to the Termination Date, payable on each Payment Date hereafter and on the Termination Date. For purposes of calculating utilization under this subsection, the Commitments shall be deemed used to the extent of the principal amount of Revolving Loans then outstanding (excluding any outstanding Swing Line Loans), plus the L/C Obligations then outstanding.

           2.6.2         The Borrower may permanently reduce the Aggregate Commitment in whole, or in part ratably among the Lenders in accordance with their respective Pro Rata Shares, in integral multiples of $1,000,000, upon at least three Business Days' written notice to the Administrative Agent, which notice shall specify the amount of any such reduction, provided that the amount of the Aggregate Commitment may not be reduced below the Total Outstandings. All accrued commitment fees shall be payable on the effective date of any termination of the obligations of the Lenders to make Revolving Loans hereunder.

            2.6.3        The Borrower may, from time to time, by means of a letter delivered to the Administrative Agent substantially in the form of Exhibit H, request that the Aggregate Commitment be increased by up to $50,000,000 in the aggregate by (i) increasing the Commitment of one or more Lenders which have agreed to such increase in their sole and absolute discretion and/or (ii) adding one or more commercial banks or other Persons as a party hereto (each an "Additional Lender") with a Commitment in an amount agreed to by any such Additional Lender; provided that no Additional Lender shall be added as a party hereto without the written consent of the Administrative Agent, the Issuer and the Swing Line Lender (which consents shall not be unreasonably withheld or delayed) or if an Unmatured Default or a Default exists. Any increase in the Aggregate Commitment pursuant to this Section 2.6.3 shall be effective three Business Days after the date on which the Administrative Agent, the Issuer and the Swing Line Lender have approved the applicable increase letter in the form of Annex 1 to Exhibit H (in the case of an increase in the Commitment of an existing Lender) or assumption letter in the form of Annex 2 to Exhibit H (in the case of the addition of a commercial bank or other Person as a new Lender). The Administrative Agent shall promptly notify the Borrower and the Lenders of any increase in the amount of the Aggregate Commitment pursuant to this Section 2.6.3 and of the Commitment of each Lender after giving effect thereto. The parties hereto agree that, notwithstanding any other provision of this Agreement, the Administrative Agent, the Borrower, each Additional Lender and each increasing Lender, as applicable, may make arrangements satisfactory to such parties to cause an Additional Lender or an increasing Lender to temporarily hold risk participations in the outstanding Advances of the other Lenders (rather than fund its Percentage of all outstanding Loans concurrently with the applicable increase) with a view toward minimizing breakage costs and transfers of funds in connection with any increase in the Aggregate Commitment. The Borrower acknowledges that if, as a result of a non-pro-rata increase in the Aggregate Commitment, any Eurodollar Loans are prepaid or converted (in whole or in part) on a day other than the last day of an Interest Period therefor, then such prepayment or conversion shall be subject to the provisions of Section 3.4.

            2.7            Mandatory Reduction of the Aggregate Commitment. On any date on which a Change of Control occurs, the Aggregate Commitment shall be immediately reduced to zero.

            2.8            Prepayments. (a) The Borrower may from time to time prepay, without penalty or premium, all outstanding Floating Rate Advances or, in an aggregate amount of $1,000,000 or a higher integral multiple of $500,000 (or, in the case of any prepayment of a Floating Rate Advance made to repay Reimbursement Obligations, in such other amount as is necessary to repay such Advance in full), any portion of the outstanding Floating Rate Advances upon notice to the Administrative Agent not later than 11:00 a.m. on the date of prepayment. The Borrower may from time to time prepay, without penalty or premium, all outstanding Eurodollar Advances or, in an aggregate amount of $1,000,000 or a higher integral multiple thereof, any portion of the outstanding Eurodollar Advances upon three Business Days' prior notice to the Administrative Agent.

            (b)            On any date on which the Aggregate Commitment is reduced pursuant to Section 2.7, the Borrower shall prepay all Revolving Loans.

            (c)            Any prepayment of a Eurodollar Loan on a day other than the last day of an Interest Period therefor shall be subject to Section 3.4.

            (d)            The Borrower may, upon notice to the Swing Line Lender (with a copy to the Administrative Agent), at any time or from time to time, voluntarily prepay Swing Line Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by the Swing Line Lender and the Administrative Agent not later than noon on the date of the prepayment, and (ii) any such prepayment shall be in a principal amount which is an integral multiple of $100,000 (except that, if at any time Swing Line Loans are made in an amount which is not an integral multiple of $100,000 upon delivery of by the Swing Line Lender of a Swing Line Loan Notice as contemplated by Section 2.21.2, the next prepayment of Swing Line Loans shall be in an amount so that the outstanding principal amount of all Swing Line Loans is either (x) zero or (y) an integral multiple of $100,000). Each such notice shall specify the date and amount of such prepayment. If such notice is given by the Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein.

            2.9            Interest Rates, etc. Each Floating Rate Advance shall bear interest on the outstanding principal amount thereof, for each day from the date such Advance is made or is converted from a Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.5 to the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.5, at a rate per annum equal to the Floating Rate for such day. Each Swing Line Loan shall bear interest on the outstanding principal amount thereof for each day from the applicable borrowing date at a rate per annum equal to the Floating Rate for such day or, so long as the Lenders have not been required to fund their participations in such Swing Ling Loan pursuant to Section 2.21.3(b), such other rate as is agreed to in writing by the Swing Line Lender and the Borrower. Changes in the rate of interest on Floating Rate Advances will take effect simultaneously with each change in the Alternate Base Rate. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from the first day of each Interest Period applicable thereto to the last day of such Interest Period at the interest rate determined by the Administrative Agent as applicable to such Eurodollar Advance based upon the Borrower's selections under Sections 2.4 and 2.5 and otherwise in accordance with the terms hereof.

            2.10            Rates Applicable After Default. Notwithstanding anything to the contrary herein, during the existence 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 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that no Advance may be made as, converted into or continued as a Eurodollar Advance. During the existence 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 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that (i) each Eurodollar 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 Floating Rate Advance and Swing Line Loan shall bear interest at a rate per annum equal to the Floating Rate in effect from time to time plus 2% per annum, provided that, during the existence of a Default under Section 7.1.6 or 7.1.7, the interest rates set forth in clauses (i) and (ii) above shall be applicable to all Advances and Swing Line Loans without any election or action on the part of the Administrative Agent or any Lender.

            2.11            Maturity. Any outstanding Advances and all other accrued and unpaid Obligations shall be paid in full by the Borrower on the scheduled Termination Date or such earlier date required by Section 2.7 or Section 8.1.

            2.12            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 XIII, or at any other Lending Installation of the Administrative Agent specified in writing by the Administrative Agent to the Borrower, by 1:00 p.m. on the date when due and (except as otherwise specifically required hereunder) shall be applied ratably by the Administrative Agent among the Lenders in accordance with their respective Pro Rata Shares. Each payment delivered to the Administrative Agent for the account of any Lender shall be delivered promptly 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 XIII or at any Lending Installation specified in a notice received by the Administrative Agent from such Lender. The Administrative Agent is hereby authorized to charge the account of the Borrower maintained with JPMorgan for each payment of principal, interest and fees as it becomes due hereunder.

            2.13            Noteless Agreement; Evidence of Indebtedness. (i)  Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

            (ii)               The Administrative Agent shall also maintain accounts in which it will record (a) the amount of each Loan made hereunder, the Type thereof and, if applicable, each Interest Period with respect thereto, (b) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, (c) the Stated Amount of each Letter of Credit and the amount of all Reimbursement Obligations and (d) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender's share thereof.

            (iii)             The entries maintained in the accounts maintained pursuant to subsections (i) and (ii) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded; provided that the failure of the Administrative Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

            (iv)            Any Lender may request that its Loans be evidenced by a Note. In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 12.3, except to the extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in subsections (i) and (ii) above.

            2.14            Telephonic Notices. The Borrower hereby authorizes the Lenders and the Administrative Agent to extend, convert or continue Loans and/or Advances, to 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, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically. The Borrower agrees to deliver promptly to the Administrative Agent a written confirmation, if such confirmation is requested by the Administrative Agent or any Lender, of each telephonic notice signed by an Authorized Officer. 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.

            2.15            Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Floating Rate Advance and on each Swing Line Loan shall be payable on each Payment Date, and at maturity (whether due to acceleration or otherwise). Interest accrued on each Eurodollar Advance shall be payable on the last day of each applicable Interest Period, on any date on which such Advance is prepaid or is converted into a Floating Rate Advance and at maturity (whether due to acceleration or otherwise). Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest and commitment fees shall be calculated for actual days elapsed on the basis of a 360-day year, except that interest accruing at the Prime Rate shall be calculated for actual days elapsed on the basis of a 365, or when appropriate 366, 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 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.

            2.16            Notification of Advances, Interest Rates, Prepayments and Commitment Reductions. Promptly after receipt thereof, the Administrative Agent will notify each Lender of the contents of each Aggregate Commitment reduction notice, 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 Eurodollar Advance promptly upon determination of such interest rate and will give each Lender prompt notice of each change in the Alternate Base Rate.

            2.17            Lending Installations. Each Lender may book its Loans 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 Loans and any Notes issued hereunder shall be deemed held by each Lender for the benefit of any such Lending Installation. Each Lender may, by written notice to the Administrative Agent and the Borrower in accordance with Article XIII, designate replacement or additional Lending Installations through which Loans will be made by it and for whose account Loan payments are to be made.

            2.18            Non-Receipt of Funds by the Administrative Agent. Unless the Borrower or 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 (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the relevant Loan or (y) in the case of payment by the Borrower, the interest rate applicable to the relevant Loan.

            2.19            Replacement of Lender. If the Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any Lender's obligation to make or continue, or to convert Advances into, Eurodollar Advances shall be suspended pursuant to Section 3.3 (any Lender so affected an "Affected Lender"), the Borrower may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Lender as a Lender party to this Agreement, provided that no Default or Unmatured Default shall have occurred and be continuing at the time of such replacement, and provided, further, that, concurrently with such replacement, (i) another bank or other entity which is reasonably satisfactory to the Borrower and the Administrative Agent shall agree, as of such date, to purchase for cash the Advances and other Obligations due to the Affected Lender pursuant to an assignment substantially in the form of Exhibit C and to become a Lender for all purposes under this Agreement and to assume all obligations of the Affected Lender to be terminated as of such date and to comply with the requirements of Section 12.3 applicable to assignments, and (ii) the Borrower shall pay to such Affected Lender in same day funds on the day of such replacement (A) all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to the date of termination, including payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5, and (B) an amount, if any, equal to the payment which would have been due to such Lender on the day of such replacement under Section 3.4 had the Revolving Loans of such Affected Lender been prepaid on such date rather than sold to the replacement Lender.

            2.20            Letters of Credit.

            2.20.1         Issuance. The Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue standby letters of credit (together with the Existing Letter of Credit, each a "Letter of Credit") and to renew, extend, increase, decrease or otherwise modify Letters of Credit ("Modify," and each such action a "Modification") from time to time from the date of this Agreement to the Termination Date upon the request of the Borrower; provided that immediately after each Letter of Credit is issued or Modified, (i) the amount of the LC Obligations shall not exceed $20,000,000 and (ii) the Total Outstandings shall not exceed the Aggregate Commitment. No Letter of Credit shall have an expiry date later than the earlier of (a) one year after the date of issuance thereof (provided that any Letter of Credit with a one-year tenor may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in the following clause (b)) and (b) five Business Days prior to the scheduled Termination Date.

            2.20.2         Participations. Upon the issuance or Modification by the Issuer of a Letter of Credit in accordance with this Section 2.20, the Issuer shall be deemed, without further action by any Person, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any Person, to have unconditionally and irrevocably purchased from the Issuer, a participation in such Letter of Credit (and each Modification thereof) and the related LC Obligations in proportion to its Pro Rata Share.

            2.20.3            Issuance or Modification of Letters of Credit. Subject to Section 2.20.1, the Borrower shall deliver an LC Application to the Issuer prior to noon at least two Business Days (or such lesser period of time as the Issuer may agree in its sole discretion) prior to the proposed date of issuance or Modification of a Letter of Credit, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Letter of Credit and, in the case of issuance of a Letter of Credit, describing the proposed terms of such Letter of Credit and the nature of the transactions proposed to be supported thereby. Upon receipt of an LC Application, the Issuer shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Lender, of the contents thereof and of the amount of each Lender's participation in such proposed Letter of Credit. The Issuer shall have no obligation to issue, or to increase the amount or extend the expiry date of, any Letter of Credit unless the conditions precedent set forth in Article IV are satisfied; it being understood that the Issuer shall have no duty to ascertain whether such conditions have been satisfied unless the Issuer has received written notice from the Borrower, the Administrative Agent or any Lender, which has not been rescinded, stating that any such condition precedent has not been satisfied. In the event of any conflict between the terms of this Agreement and the terms of any LC Application, the terms of this Agreement shall control.

            2.20.4            Letter of Credit Fees. The Borrower shall pay to the Administrative Agent, for the account of the Lenders ratably in accordance with their respective Pro Rata Shares, with respect to each Letter of Credit, a letter of credit fee at a rate per annum equal to the LC Fee Rate in effect from time to time on the Stated Amount of such Letter of Credit, such fee to be payable in arrears on each Payment Date, on the Termination Date and thereafter (if applicable) on demand; provided that during the existence 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 8.2 requiring unanimous consent of the Lenders to changes in fees), declare that such fee shall be calculated based upon the LC Fee Rate plus 2%. The Borrower shall also pay to the Issuer for its own account (x) a fronting fee of 0.125% per annum on the Stated Amount of each Letter of Credit, with such fee to be payable in arrears on each Payment Date, and (y) documentary and processing charges in connection with the issuance or Modification of and draws under Letters of Credit in accordance with the Issuer's standard schedule for such charges as in effect from time to time.

            2.20.5            Reimbursement by Borrower. Promptly upon receipt from the beneficiary of any Letter of Credit of any demand for payment under such Letter of Credit, the Issuer shall notify the Administrative Agent, and upon receipt of such notice the Administrative Agent shall promptly notify the Borrower and each other Lender, as to the amount to be paid by the Issuer as a result of such demand and the proposed payment date. If the Issuer honors such demand for payment, the Issuer shall promptly notify the Borrower and the Borrower shall be irrevocably and unconditionally obligated to reimburse the Issuer for such payment not later than noon (i) if notice of such payment is received from the Issuer prior to 10:45 a.m. on a Business Day, on such Business Day, or (ii) otherwise, on the Business Day immediately following the Borrower's receipt of such notice (it being understood that, subject to the other terms and conditions of this Agreement, the Borrower may request Advances to pay Reimbursement Obligations hereunder and that, in determining whether the making of any Advance would cause the Total Outstandings to exceed the Aggregate Commitment, any Reimbursement Obligation that will be paid with the proceeds of such Advance shall be deemed not to be outstanding). Any amount paid by the Issuer under a Letter of Credit and not reimbursed by the Borrower on the date of such payment shall bear interest, payable on demand, at a rate per annum equal to (a) for any day prior to the date on which such payment by the Borrower is due in accordance with the foregoing sentence, the Federal Funds Effective Rate, and (b) thereafter, the rate applicable to Floating Rate Advances plus, beginning on the first Business Day after such payment is due, 2%.

            2.20.6            Reimbursement by Lenders. If and to the extent that the Borrower fails to reimburse the Issuer for any payment under a Letter of Credit by the time required by Section 2.20.5, each Lender (other than the Issuer in its capacity as a Lender) shall be unconditionally and irrevocably obligated, without regard to the occurrence of any Default or Unmatured Default or any condition precedent whatsoever, to pay the Issuer on demand (i) such Lender's Pro Rata Share of such unreimbursed amount plus (ii) interest on the amount payable by such Lender, for each day from the date of the applicable payment by the Issuer to the date on which the Issuer receives payment from such Lender, at a rate per annum equal to the Federal Funds Effective Rate or, beginning on third Business Day after demand for such amount by the Issuer, the rate applicable to Floating Rate Advances. The Issuer will pay to each Lender, ratably in accordance with its Pro Rata Share, any amount received by it from the Borrower for application in payment, in whole or in part, to amounts owed by the Borrower in respect of any drawing under a Letter of Credit, together with interest paid by the Borrower thereon, but only to the extent (and, in the case of interest, for the relevant period of time after) such Lender made payment to the Issuer in respect of such drawing pursuant to this Section 2.20.6.

            2.20.7            Obligations Absolute. The Borrower's obligation to reimburse the Issuer for each drawing under a Letter of Credit 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 Issuer, any Lender or any beneficiary of a Letter of Credit. The Borrower further agrees with the Issuer and the Lenders that neither the Issuer nor any Lender shall be responsible for, and the Reimbursement Obligations in respect of any Letter of Credit shall not be affected by, among other things, any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, 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 Letter of Credit or any financing institution or other Person to whom any Letter of Credit may be transferred or any claim or defense whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Letter of Credit or any such transferee. The Borrower agrees that any action taken or omitted by the Issuer or any Lender under or in connection with any 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 Issuer or any Lender under any liability to the Borrower. Notwithstanding the foregoing or any other provision of this Agreement, the Borrower shall not be precluded from asserting any claim for direct (but not consequential) damages suffered by the Borrower to the extent, but only to the extent, caused by (i) the gross negligence or willful misconduct of the Issuer in determining whether a request presented under any Letter of Credit complied with the terms of such Letter of Credit, (ii) the Issuer's failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit or (iii) the gross negligence or willful misconduct of the Administrative Agent or any Lender in giving a notice of the type described in the second-to-last sentence of Section 2.20.3.

            2.20.8            Actions of Issuer. The Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Letter of Credit, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, facsimile, telex or teletype message, statement, order or other document believed in good faith 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 Issuer. The Issuer 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 Section 2.20, the Issuer 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 holder of a participation in any Letter of Credit. Without limiting the foregoing, the responsibility of the Issuer to the Borrower and each Lender with respect to any requested drawing under a Letter of Credit shall be only to determine that the documents delivered under such Letter of Credit in connection with a demand for payment appear on their face to be in conformity in all material respects with such Letter of Credit.

            2.20.9            Indemnification. The Borrower agrees to indemnify and hold harmless each Lender, the Issuer 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 Issuer or the Administrative Agent may incur (or which may be claimed against such Lender, the Issuer 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 Letter of Credit or any actual or proposed use of any Letter of Credit, including any claims, damages, losses, liabilities, costs or expenses which the Issuer 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 Issuer hereunder (but nothing herein contained shall affect any right the Borrower may have against any defaulting Lender) or (ii) by reason of or on account of the Issuer issuing any Letter of Credit which specifies that the term "Beneficiary" therein includes any successor by operation of law of the named Beneficiary, but which 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 Issuer, evidencing the appointment of such successor Beneficiary; provided that the Borrower shall not be required to indemnify any Lender, the Issuer or the Administrative Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by any event described in clause , (ii) or (iii) of the last sentence of Section 2.20.7. Nothing in this Section 2.20.9 is intended to limit the obligations of the Borrower under any other provision of this Agreement.

            2.20.10            Lenders' Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the Issuer and 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 charges), claim, demand, action, loss or liability (except such as result from such indemnitees' gross negligence or willful misconduct or the Issuer's failure to pay under any Letter of Credit after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit) that such indemnitees may suffer or incur in connection with this Section 2.20 or any action taken or omitted by such indemnitees hereunder.

            2.20.11           LC Collateral Account. The Borrower agrees that, if any Letter of Credit is outstanding on the Termination Date, it will establish on such date (or on such earlier date as may be required pursuant to Section 8.1), and thereafter maintain so long as any Letter of Credit is outstanding or any amount is payable to the Issuer or the Lenders in respect of any Letter of Credit, a special collateral account pursuant to arrangements satisfactory to the Administrative Agent (the "LC Collateral Account") at the Administrative Agent's office at the address specified pursuant to Article XIII, 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 8.1. The Borrower hereby pledges, assigns and grants to the Administrative Agent, on behalf of and for the ratable benefit of the Lenders and the Issuer, a security interest in all of the Borrower's right, title and interest in and to all funds which may from time to time be on deposit in the LC Collateral Account, to secure the prompt and complete payment and performance of the Obligations. The Administrative Agent will invest any funds on deposit from time to time in the LC Collateral Account in certificates of deposit of JPMorgan having a maturity not exceeding 30 days. The Administrative Agent agrees that when all Obligations have been paid in full and all Letters of Credit have expired or been terminated, the Administrative Agent will deliver all remaining funds in the LC Collateral Account to the Borrower (or such other Person as is entitled thereto under applicable law). If the Administrative Agent determines that any Person other than the Borrower is entitled to such remaining funds, the Administrative Agent shall use reasonable efforts to give the Borrower notice of such determination in advance of delivering such funds to any other Person, but the Administrative Agent shall have no liability for the failure to deliver such notice.

            2.20.12       Rights as a Lender. In its capacity as a Lender, the Issuer shall have the same rights and obligations as any other Lender.

            2.21            Swing Line Loans.

            2.21.1         Amount of Swing Line Loans. Upon the satisfaction of the applicable conditions precedent set forth in Article IV, from and including the date of this Agreement and prior to the Termination Date, the Swing Line Lender agrees, on the terms and conditions set forth in this Agreement, to make Swing Line Loans to the Borrower from time to time in an aggregate principal amount not to exceed $20,000,000 notwithstanding the fact that such Swing Line Loans, when aggregated with such Lender's Pro Rata Share of Revolving Loans and L/C Obligations hereunder may exceed the amount of such Lender's Commitment; provided that the Total Outstandings shall not at any time exceed the Aggregate Commitment. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Swing Line Loans at any time prior to the Termination Date.

            2.21.2          Method of Borrowing. Not later than 1:00 p.m. on the Borrowing Date of each Swing Line Loan, the Borrower shall deliver to the Administrative Agent and the Swing Line Lender irrevocable notice (a "Swing Line Loan Notice") specifying (i) the applicable Borrowing Date (which date shall be a Business Day), and (ii) the aggregate amount of the requested Swing Line Loan, which shall be an integral multiple of $100,000.

            2.21.3          Making of Swing Line Loans. Promptly after receipt of a Swing Line Loan Notice, the Administrative Agent shall notify each Lender by fax, or other similar form of transmission, of the requested Swing Line Loan. Not later than 3:00 p.m. on the applicable Borrowing Date, the Swing Line Lender shall make available the Swing Line Loan, in funds immediately available in [New York City], to the Administrative Agent at its address specified pursuant to Article XIII. The Administrative Agent will promptly make the funds so received from the Swing Line Lender available to the Borrower on the Borrowing Date at the Administrative Agent's aforesaid address.

            2.21.4        Repayment of Swing Line Loans. The Swing Line Lender may, at any time in its sole discretion, by notice to the Administrative Agent not later than noon on any day (which shall promptly notify each Lender), require each Lender (including the Swing Line Lender) to make a Revolving Loan in the amount of such Lender's Pro Rata Share 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 2:00 p.m. on the date of any notice received pursuant to this Section 2.21.4, each Lender shall make available its required Revolving Loan, in funds immediately available in Chicago to the Administrative Agent at its address specified pursuant to Article XIII. Revolving Loans made pursuant to this Section 2.21.4 shall initially be Floating Rate Loans and thereafter may be continued as Floating Rate Loans or converted into Eurodollar Loans in the manner provided in Section 2.5 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 the making of any Swing Line Loan, that any applicable condition precedent set forth in Article IV had not then been satisfied, such Lender's obligation to make Revolving Loans pursuant to this Section 2.21.4 to repay Swing Line Loans shall be unconditional, continuing, irrevocable and absolute and shall not be affected by any circumstance, including, (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 circumstance, happening or event whatsoever. If any Lender fails to make payment to the Administrative Agent of any amount due under this Section 2.21.4, 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 reasons any Lender fails to make payment to the Administrative Agent of any amount due under this Section 2.21.4, 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 Revolving Loan, 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.

ARTICLE III

YIELD PROTECTION; TAXES

            3.1            Yield Protection. (a)  If, on or after the date of this Agreement, (x) the adoption of or any change in any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or (y) 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 (z) compliance by any Lender or applicable Lending Installation with any request or directive (whether or not having the force of law) issued on or after the date hereof of any such authority, central bank or comparable agency:

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

            (ii)            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 (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or

            (iii)           imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation of making, funding or maintaining its Eurodollar Loans or of issuing or participating in Letters of Credit or reduces any amount receivable by any Lender or any applicable Lending Installation in connection with its Eurodollar Loans or its issuance of or participations in Letters of Credit, or requires any Lender or any applicable Lending Installation to make any payment calculated by reference to the amount of Eurodollar Loans held or interest received, or Letters of Credit issued or participated in, by it, by an amount deemed material by such Lender,

and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation of making or maintaining its Eurodollar Loans or Commitment or issuing or participating in Letters or Credit or to reduce the return received by such Lender or applicable Lending Installation in connection with such Eurodollar Loans, such Commitment or the Letters of Credit, then, within 15 days of demand by such Lender, the Borrower shall pay such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction in amount received. A Lender shall not be entitled to demand compensation or be compensated hereunder to the extent that such compensation relates to any period of time more than 60 days prior to the date upon which such Lender first notified the Borrower of the occurrence of the event entitling such Lender to such compensation (unless, and to the extent, that any such compensation so demanded shall relate to the retroactive application of any event so notified to the Borrower).

            (b)            Without limiting subsection (a) above, any Lender may require the Borrower to pay, contemporaneously with each payment of interest on any Eurodollar Loan of such Lender, additional interest on such Eurodollar Loan at a rate per annum determined by such Lender up to but not exceeding the excess of (i) (A) the applicable Eurodollar Base Rate divided by (B) one minus the Reserve Requirement over (ii) the applicable Eurodollar Base Rate. Any Lender wishing to require payment of such additional interest (x) shall so notify the Borrower and the Administrative Agent, in which case such additional interest on the Eurodollar Loans of such Lender shall be payable to such Lender at the place indicated in such notice with respect to each Interest Period commencing at least three Business Days after the giving of such notice and (y) shall notify the Borrower at least five Business Days prior to each date on which interest is payable on any Eurodollar Loan of the amount then due it under this Section 3.1.

            3.2            Changes in Capital Adequacy Regulations. If a Lender determines the amount of capital required or expected to be maintained by such Lender, any Lending Installation of such Lender or any corporation controlling such Lender is increased as a result of a Change, then, within 15 days of demand by such Lender, the Borrower shall pay such Lender the amount necessary to compensate for any shortfall in the rate of return on the portion of such increased capital which such Lender determines is attributable to this Agreement, its Loans, its Commitment or its obligation to issue or participate in Letters of Credit (after taking into account such Lender's policies as to capital adequacy). "Change" means (i) any change after the date of this Agreement in the Risk-Based Capital Guidelines 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 any Lending Installation or any corporation controlling any Lender. "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 Basle 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.

            3.3            Availability of Types of Advances. If any Lender reasonably determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or if the Required Lenders reasonably determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the Eurodollar Base Rate does not accurately reflect the cost of obtaining funds to make or maintain Eurodollar Advances, then the Administrative Agent shall suspend the availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances (on or before the date required by such law, rule, regulation or directive), subject to the payment of any funding indemnification amounts required by Section 3.4.

            3.4            Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made, continued or converted on a date specified by the Borrower for any reason other than default by the Lenders, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Rate Advance.

            3.5            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 3.5) 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 LC Application or from the execution or delivery of, or otherwise with respect to, this Agreement, any Note or any LC Application ("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 any Taxes or Other Taxes imposed on amounts payable under this Section 3.5) 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 3.6.

            (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 less 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 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 subsection (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 3.5 with respect to Taxes imposed by the United States; provided that, should a Non-U.S. Lender which is otherwise exempt from or subject to a reduced rate of withholding tax become subject to Taxes because of its failure to deliver a form required under subsection (iv), above, the Borrower shall take such steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender to recover such Taxes.

            (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.

            (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 3.5(vii) shall survive the payment of the Obligations and termination of this Agreement.

            3.6            Lender Statements; Survival of Indemnity. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of Eurodollar Advances under Section 3.3, so long as such designation is not, in the reasonable judgment of such Lender, disadvantageous to such Lender. 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 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be rebuttable presumptive evidence of the amount thereof. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Base Rate applicable to such Eurodollar Loan, whether in fact that is the case or not. The obligations of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement.

ARTICLE V

REPRESENTATIONS AND WARRANTIES

            The Borrower represents and warrants to the Lenders that:

            5.1            Organization. The Borrower and each of its Subsidiaries are duly organized, validly existing and in good standing under the laws of the states of their organization and have all requisite authority to conduct their respective businesses in each jurisdiction in which the failure to have such authority, singly or in the aggregate, could reasonably be expected to have a Material Adverse Effect. The Borrower and each of its Subsidiaries have full power and authority to carry on their business as now conducted.

            5.2            Authorization and Validity. The Borrower and each Guarantor has the power and authority and legal right to execute and deliver the Loan Documents to which it is a party and to perform its obligations thereunder. The execution and delivery by the Borrower and each Guarantor of the Loan Documents to which it is a party have been duly authorized by proper organizational proceedings, and the Loan Documents to which the Borrower and such Guarantor is a party constitute legal, valid and binding obligations of the Borrower or such Guarantor, as the case may be, enforceable against the Borrower or such Guarantor, as the case may be, in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally.

            5.3            Financial Statements. The December 31, 2003 and the September 30, 2004 consolidated financial statements of the Borrower and the Subsidiaries heretofore delivered to the Administrative Agent and the Lenders were prepared in accordance with generally accepted accounting principles in effect on the date such statements were prepared and fairly present the financial position and results of operations of the Borrower and its Subsidiaries at such dates and the consolidated results of their operations for the periods then ended.

            5.4            Subsidiaries. Schedule 5.4 contains an accurate list of all of the presently existing Subsidiaries, setting forth their respective jurisdictions of organization and the percentage of their respective capital stock or membership interests owned by the Borrower or other Subsidiaries. All of the issued and outstanding shares of capital stock of each corporate Subsidiary have been duly authorized and issued and are fully paid and nonassessable.

            5.5            ERISA. Each Plan is in material compliance with, and has been administered in material compliance with, all applicable provisions of ERISA, the Code and any other applicable federal or state law, except where the failure to so comply would not (individually or in the aggregate) reasonably be expected to have a Material Adverse Effect, and no event or condition has occurred and is continuing as to which the Borrower is under an obligation to furnish a report to the Administrative Agent and the Lenders under Section 6.1(d) and which would reasonably be expected (individually or in the aggregate) to have a Material Adverse Effect.

            5.6            Defaults. No Default or Unmatured Default has occurred and is continuing.

            5.7            Accuracy of Information. No information, exhibit or report furnished by the Borrower or any Subsidiary to the Administrative Agent or any Lender in connection with the negotiation of this Agreement contains any material misstatement of fact or omitted to state a material fact necessary to make the statements contained therein not misleading.

            5.8            Regulation U. Neither the Borrower nor any Subsidiary is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying Margin Stock. Margin Stock constitutes less than 25% of the consolidated assets of the Borrower and its Subsidiaries which are subject to any limitation on sale or pledge or any other restriction hereunder. No part of the proceeds of any Loan will be used to purchase or carry any Margin Stock in violation of Regulation U.

            5.9            Taxes. The Borrower and its Subsidiaries have filed all United States federal tax returns and all other tax returns which, to the Knowledge of the Borrower, are required to be filed and have paid all taxes due pursuant to said returns or material taxes due pursuant to any assessment received by the Borrower or any Subsidiary, except in both cases such taxes, if any, as are being contested in good faith and as to which adequate reserves have been provided in accordance with Agreement Accounting Principles. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of any taxes or other governmental charges are adequate in accordance with Agreement Accounting Principles.

            5.10        Liens. There are no Liens on any of the properties or assets of the Borrower or any Subsidiary except (i) Liens permitted by Section 6.3.2 and (ii) with respect to properties and assets other than Productive Properties, Principal Transmission Facilities and the stock of any Subsidiary, Liens that could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. All easements, rights of way, licenses and other real property rights required for operation of the businesses of the Borrower and its Subsidiaries (collectively the "Rights of Way") are owned free and clear of any Lien, other than Liens permitted by this Agreement and Liens already on any parcel of real property with respect to which the Rights of Way have been granted, which will not, in the aggregate, at any time materially detract from the value of the Rights of Way or materially impair the use of the Rights of Way in the operation of the businesses of the Borrower and its Subsidiaries.

            5.11        Compliance with Orders. Neither the Borrower nor any Subsidiary is in default under the terms of any order of any federal or state court or administrative agency by which it or any of its properties may be bound, except for any defaults which could not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect.

            5.12        Litigation. Except as set forth in Schedule 5.12, there are no actions at law or in equity pending or, to the Knowledge of the Borrower, threatened involving the likelihood of any judgment or liability against the Borrower or any Subsidiary which could reasonably be expected to have a Material Adverse Effect.

            7.1.8        Involuntary Bankruptcy, etc. Without the application, approval or consent of the Borrower, the applicable Material Subsidiary or the applicable Material Group of Subsidiaries, a receiver, trustee, examiner, liquidator or similar official shall be appointed for the Borrower, any Material Subsidiary or such Material Group of Subsidiaries, or a proceeding described in Section 7.1.7(iv) shall be instituted against the Borrower, any Material Subsidiary or such Material Group of Subsidiaries and such appointment continues undischarged or such proceeding continues undismissed or unstayed for a period of 60 consecutive days.

ARTICLE VIII

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES;
RELEASES OF GUARANTORS

            8.1            Acceleration. If any Default described in Section 7.1.6 or 7.1.7 occurs with respect to the Borrower, the obligations of the Lenders to make Loans hereunder and the obligation and power of the Issuer to issue Letters of Credit shall automatically terminate, the Obligations shall immediately become due and payable without any election or action on the part of the Administrative Agent or any Lender and the Borrower will become immediately obligated, without any further notice, act or demand, to pay to the Administrative Agent an amount in immediately available funds, which funds shall be held in the LC Collateral Account, equal to the excess of (i) the amount of LC Obligations at such time over (ii) the amount on deposit in the LC Collateral Account at such time which is free and clear of all rights and claims of third parties and has not been applied against the Obligations (such difference, the "Collateral Shortfall Amount"). If any other Default occurs, the Required Lenders (or the Administrative Agent with the consent of the Required Lenders) may (x) terminate or suspend the obligations of the Lenders to make Loans hereunder and the obligation and power of the Issuer to issue 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, and (y) upon notice to the Borrower and in addition to the continuing right to demand payment of all amounts payable under this Agreement, make demand on the Borrower to pay, and the Borrower will, forthwith upon such demand and without any further notice or act, pay to the Administrative Agent in immediately available funds the Collateral Shortfall Amount, which funds shall be deposited in the LC Collateral Account.

            If, within 30 days after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Loans hereunder as a result of any Default (other than any Default as described in Section 7.1.6 or 7.1.7 with respect to the Borrower) and before any judgment or decree for the payment of the Obligations due 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.

            8.2            Amendments. Subject to the provisions of this Article VIII, the Required Lenders (or the Administrative Agent with the consent in writing of the Required Lenders) and the Borrower may enter into agreements supplemental hereto for the purpose of adding to or modifying any provision in any Loan Document or changing in any manner the rights of the Lenders or the Borrower hereunder or waiving any Default hereunder; provided that no such supplemental agreement shall, without the consent of all of the Lenders:

            (i)            Extend the final maturity of any Loan or Reimbursement Obligation or forgive all or any portion of the principal amount thereof, or reduce the rate or extend the time of payment of interest or fees thereon or extend the expiry date of any Letter of Credit to a date after the scheduled Termination Date.

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

            (iii)            Extend the Termination Date or, except pursuant to Section 2.6.3, increase the amount of the Aggregate Commitment or of the Commitment of any Lender hereunder, or permit the Borrower to assign its rights under this Agreement.

            (iv)            Amend the last paragraph of Section 6.3.1 or this Section 8.2.

            (v)            Release any Guarantor from its obligations under the Subsidiary Guaranty (except as provided in Section 8.4).

No amendment of any provision of this Agreement relating to the Administrative Agent shall be effective without the written consent of the Administrative Agent. No amendment of any provision of this Agreement relating to the Issuer shall be effective without the written consent of the Issuer. No amendment of any provision of this Agreement relating to the Swing Line Lender shall be effective without the written consent of the Swing Line Lender. The Administrative Agent may waive payment of the fee required under Section 12.3.2 without obtaining the consent of any other party to this Agreement.

            8.3            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 Credit Extension notwithstanding the existence of a Default or the inability of the Borrower to satisfy the conditions precedent to such Credit Extension 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 8.2, 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.

            8.4            Releases of Guarantors. The Lenders hereby authorize the Administrative Agent to, and the Administrative Agent agrees that it will, release any Guarantor from its obligations under the Subsidiary Guaranty so long as (a) no Default or Unmatured Default exists or will result therefrom and (b) either (i) such Guarantor ceases to be a Subsidiary as a result of a transaction permitted hereunder or (ii) the Borrower requests such release in writing and, after giving effect thereto, the Borrower will be in compliance with Section 6.2.7. In determining whether any such release is permitted, the Administrative Agent may rely on a certificate from the Borrower. The Administrative Agent shall promptly notify the Lenders of any such release.

The obligations of the Borrower under this Section 9.6 shall survive the termination of this Agreement.

            9.7            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.

            9.10        Nonliability of Lenders.

None of the Administrative Agent, either Arranger or 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. The Borrower agrees that, except as otherwise expressly provided in this Agreement, none of the Administrative Agent, either Arranger or any Lender shall have liability to the Borrower (whether sounding in tort, contract or otherwise) for losses suffered by the Borrower in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought. None of the Administrative Agent, either Arranger or any Lender shall have any liability with respect to, and the Borrower hereby waives, releases and agrees not to sue for, any special, indirect or consequential damages suffered by the Borrower in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.

            9.11        Confidentiality.

    ARTICLE X

THE ADMINISTRATIVE AGENT

            10.1            Appointment; Nature of Relationship. JPMorgan is hereby appointed by each of the Lenders as the Administrative Agent hereunder and under each other Loan Document, and each of the Lenders irrevocably authorizes the Administrative 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 Administrative Agent agrees to act as Administrative Agent upon the express conditions contained in this Article X. Notwithstanding the use of the defined term "Administrative Agent," it is expressly understood and agreed that the Administrative Agent shall not have any fiduciary responsibilities to any Lender by reason of this Agreement or any other Loan Document and that Administrative 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 Administrative Agent, (i) the Administrative Agent does not assume any fiduciary duties to any of the Lenders, (ii) the Administrative Agent is a "representative" of the Lenders within the meaning of Section 9-105 of the Uniform Commercial Code and (iii) the Administrative Agent 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 no claim against the Administrative Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby waives.

            10.2            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 not have any 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.

            10.3            General Immunity. Neither the Administrative Agent nor any of the Administrative Agent's directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender for any action taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final non-appealable judgment by a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Person.

            10.4            No Responsibility for Loans, Recitals, etc. Neither the Administrative Agent nor any of the Administrative Agent's directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (b) the performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including any agreement by an obligor to furnish information directly to each Lender; (c) the satisfaction of any condition specified in Article IV, except for the receipt of items required to be delivered solely to Administrative Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith; or (f) the financial condition of the Borrower or of any of the Borrower's Subsidiaries. The Administrative Agent shall not have any 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 the Administrative Agent or in its individual capacity).

            10.5            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, when expressly required hereunder, all of the Lenders), and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. The Lenders hereby acknowledge that the Administrative Agent shall not be under any duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the Required Lenders. Each 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 satisfaction by the Lenders (ratably in accordance with their respective Pro Rata Shares) against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action. The Administrative Agent agrees, upon the request of any Lender at any time an Unmatured Default exists, to give a written notice to the Borrower of the type described in Section 7.1.3 or 7.1.4.

            10.6            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 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 agents or attorneys-in-fact selected by it with reasonable care. The Administrative Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Administrative Agent and the Lenders and all matters pertaining to the Administrative Agent's duties hereunder and under any other Loan Document.

            10.7            Reliance on Documents; Counsel. 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.

            10.8            Administrative Agent's Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Administrative Agent, ratably in accordance with their respective Pro Rata Shares, (i) for any amounts not reimbursed by the Borrower for which the Administrative Agent is entitled to reimbursement by the Borrower under the Loan Documents, (ii) for any other expenses incurred by the Administrative Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including for any expenses incurred by the Administrative Agent in connection with any dispute between the Administrative Agent and any Lender or between two or more of the Lenders) 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 (including for any such amounts incurred by or asserted against the Administrative Agent in connection with any dispute between the Administrative Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents, provided that (i) no Lender shall be liable to the Administrative Agent for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Administrative Agent and (ii) any indemnification required pursuant to Section 3.5(vii) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions thereof. The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Agreement.

            10.9            Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Administrative Agent has received written notice from a Lender or the Borrower referring to this Agreement describing such Default or Unmatured Default and stating that such notice is a "notice of default". In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give prompt notice thereof to the Lenders.

            10.10           Rights as a Lender. In the event the Administrative Agent is a Lender, the Administrative Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Loans 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 and its Affiliates 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. The Administrative Agent, in its individual capacity, is not obligated to remain a Lender.

            10.11        Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, either Arranger 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, either Arranger 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.

            10.11        Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, such resignation 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. The Administrative Agent may be removed at any time with or without 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; provided that the Administrative Agent may not be removed unless the Administrative Agent (in its individual capacity) and any affiliate thereof acting as Issuer is relieved of all of its duties as Issuer pursuant to documentation reasonably satisfactory to such Person on or prior to the date of such removal. Upon any resignation or removal of the Administrative Agent, the Required Lenders shall have the right (with, so long as no Default or Unmatured Default exists, the consent of the Borrower, which shall not be unreasonably withheld) 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. Notwithstanding the previous sentence, the Administrative Agent may at any time without the consent of any Lender and with the consent of the Borrower, not to be unreasonably withheld or delayed, appoint any of its Affiliates which is a commercial bank as a successor Administrative Agent hereunder. If the Administrative Agent has resigned or been removed and no successor Administrative Agent has been appointed, the Lenders may 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 Administrative Agent has accepted the appointment. Any such successor Administrative Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. 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 shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of the Administrative Agent, the provisions of this Article X shall continue in effect for the benefit of the such Person in respect of any actions taken or omitted to be taken by such Person while such Person was acting as Administrative Agent hereunder and under the other Loan Documents. In the event that there is a successor to the Administrative Agent by merger, or the Administrative Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term "Prime Rate" as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Administrative Agent.

            10.13        Delegation to Affiliates. The Borrower and the Lenders agree that the Administrative Agent may delegate any of its duties under this Agreement to any of its respective Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Administrative Agent is entitled under Articles IX and X.

            10.14        Other Agents. No Lender identified on the cover page or the signature pages of this Agreement or otherwise herein, or in any amendment hereof or other document related hereto, as being the "Syndication Agent", a "Co-Documentation Agent", a "Managing Agent" or a "Co-Agent" shall have any right, power, obligation, liability, responsibility or duty under this Agreement in such capacity other than those applicable to all Lenders. Each Lender acknowledges that it has not relied, and will not rely, on any Person so identified in deciding to enter into this Agreement or in taking or refraining from taking any action hereunder or pursuant hereto.

ARTICLE XI

SETOFF; RATABLE PAYMENTS

            11.1            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 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 or any Affiliate of 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 thereof, shall then be due.

            11.2            Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Loans or its participation in Letters of Credit or Swing Line Loans (other than payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Loans (or participations in Letters of Credit and Swing Line Loans) held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of all Loans (and participations in Letters of Credit and Swing Line 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 respective Pro Rata Shares. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

            12.1            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 12.3. The parties to this Agreement acknowledge that clause (ii) of the foregoing sentence relates only to absolute assignments and does not prohibit assignments creating security interests, including any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank; provided that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Administrative Agent may treat the Person which made any Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 12.3; provided that the Administrative Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Loan or which holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment 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 owner of the rights to any Loan (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Loan.

            12.2           Participations.

            12.2.1        Permitted Participants; Effect. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time sell to one or more banks or other entities ("Participants") 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. 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 owner of its Loans and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement (including under Article III) 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.

            12.2.2        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 Credit Extension 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 Credit Extension or Commitment, extends the Termination Date, postpones any date fixed for any regularly scheduled payment of principal of, or interest or fees on, any such Credit Extension or Commitment or releases any Guarantor from its obligations under the Subsidiary Guaranty (except as provided in Section 8.4).

            12.3            Assignments.

            12.3.1        Permitted Assignments. Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more banks or other entities ("Purchasers") all or any part of its rights and obligations under the Loan Documents. Such assignment shall be substantially in the form of Exhibit C or in such other form as may be agreed to by the parties thereto. The consents of the Borrower, the Administrative Agent, the Issuer and the Swing Line Lender (which consents shall not be unreasonably withheld or delayed by any such party) shall be required prior to an assignment becoming effective with respect to a Purchaser which is not a Lender or an Affiliate thereof; provided that if a Default has occurred and is continuing, the consent of the Borrower shall not be required; provided, further, that no assignment shall be permitted if, as of the date thereof, any event or circumstance exists which would result in the Borrower being obligated to pay any greater amount hereunder to the Purchaser than the Borrower is obligated to pay to the assigning Lender. Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate thereof shall (unless each of the Borrower and the Administrative Agent otherwise consents) be in an amount not less than the lesser of (i) $5,000,000 or (ii) the remaining amount of the assigning Lender's Commitment (calculated as at the date of such assignment) or outstanding Loans and participations in Letters of Credit and Swing Line Loans (if the Commitments have been terminated).

            12.3.2        Effect; Effective Date. Upon (i) delivery to the Administrative Agent of an assignment, together with any consents required by Section 12.3.1, and (ii) payment of a $3,500 fee to the Administrative Agent for processing such assignment (unless such fee is waived by the Administrative Agent), such assignment shall become effective on the effective date specified in such assignment. The 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 constitutes "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 or on behalf of 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 12.3.2, the transferor Lender, the Administrative Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate, 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 respective Commitments, as adjusted pursuant to such assignment.

            12.4            Dissemination of Information. The Borrower authorizes each Lender to disclose 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 any and all information in such Lender's possession concerning the creditworthiness of the Borrower and its Subsidiaries, including any information contained in any Reports; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.11 of this Agreement.

            12.5            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 3.5(iv) and the Borrower shall not be required to indemnify such Transferee pursuant to Section 3.5 hereof for any Taxes withheld as a result of the failure of the Transferee to so comply.

ARTICLE XIII

ARTICLE XIV

COUNTERPARTS

            This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart.

ARTICLE XV

CHOICE OF LAW; CONSENT TO JURISDICTION;
WAIVER OF JURY TRIAL; MAXIMUM INTEREST RATE

            15.1            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 (INCLUDING 735 ILCS SECTION 105/5-1 ET SEQ, BUT OTHERWISE WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS) OF THE STATE OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

            15.2            CONSENT TO JURISDICTION. THE BORROWER HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR ILLINOIS STATE COURT SITTING IN CHICAGO, ILLINOIS IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER 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 BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY 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.

            15.3            WAIVER OF JURY TRIAL. 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.

            15.4            Maximum Interest Rate. No provision of the Loan Documents shall require the payment or permit the collection of interest in excess of the maximum permitted by applicable law ("Maximum Rate"). If any interest in excess of the Maximum Rate is provided for or shall be adjudicated to be provided for in the Notes or otherwise in connection with this Agreement, the provisions of this Section 15.4 shall govern and prevail and neither the Borrower nor the sureties, guarantors, successors or assigns of the Borrower shall be obligated to pay the excess amount of the interest or any other excess sum paid for the use, forbearance, or detention of sums loaned. In the event the Administrative Agent or any Lender ever receives, collects or applies as interest any amount in excess of the Maximum Rate, the amount by which such amount exceeds the Maximum Rate shall be applied as a payment and reduction of the principal of indebtedness evidenced by the Loans, and, if the principal amount of the Loans has been paid in full, any remaining excess shall forthwith be paid to the Borrower.

ARTICLE XVI

AMENDMENT AND RESTATEMENT OF EXISTING AGREEMENT

            The Borrower and the Lenders agree that, at the Effective Time, (i) the Existing Agreement shall be deemed to be restated in the form hereof; it being understood that all provisions thereof which by their terms survive any termination thereof shall continue in full force and effect (without duplicating the obligations of any Person under this Agreement); and (ii) the Pro Rata Shares of the Lenders shall be reallocated in accordance with the terms hereof.

            To facilitate the allocation described in the preceding paragraph, at the Effective Time, (i) all "Loans" under the Existing Agreement ("Existing Loans") shall be deemed to be Revolving Loans, (ii) each Lender shall transfer to the Administrative Agent an amount equal to the excess, if any, of such Lender's pro rata share (according to its Pro Rata Share) of the outstanding Revolving Loans hereunder (including any Revolving Loans made at the Effective Time) over the amount of all of such Lender's Existing Loans, (iii) the Administrative Agent shall apply the funds received from the Lenders pursuant to clause (ii), first, to purchase from each Lender which has Existing Loans in excess of such Lender's pro rata share (according to its Pro Rata Share) of the outstanding Revolving Loans hereunder (including any Revolving Loans made upon the effectiveness of this Agreement), a portion of such Existing Loans equal to such excess, second, to pay to each Lender all interest, fees and other amounts (including amounts payable pursuant to Section 3.4 of the Existing Agreement, assuming for such purpose that the Existing Loans were prepaid rather than allocated at the Effective Time) owed to such Lender under the Existing Agreement (whether or not otherwise then due) and, third, as the Borrower shall direct, and (iv) all Revolving Loans shall commence new Interest Periods in accordance with elections made by the Borrower at least three Business Days prior to the date hereof pursuant to the procedures applicable to conversions and continuations set forth in Section 2.5 (all as if the Existing Loans were continued or converted at the Effective Time). To the extent the Borrower fails to make a timely election pursuant to clause (iv) of the preceding sentence with respect to any Revolving Loans, such Revolving Loans shall be Floating Rate Loans.

ARTICLE XVII

USA PATRIOT ACT NOTIFICATION

            The following notification is provided to the Borrower pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318: IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify and record information that identifies each person or entity that opens an account, including any deposit account, treasury management account, loan, other extension of credit or other financial services product. What this means for the Borrower: When the Borrower opens an account, the Lenders will ask for the Borrower's name, tax identification number, business address and other information that will allow the Administrative Agent and the Lenders to identify the Borrower. The Administrative Agent and the Lenders may also ask to see the Borrower's legal organizational documents or other identifying documents.

            IN WITNESS WHEREOF, the Borrower, the Lenders and the Administrative Agent have executed this Agreement as of the date first above written.

EXHIBIT B
FORM OF OPINION

January 4, 2005

The Administrative Agent and the Lenders who are parties to the
Credit Agreement described below.

Gentlemen/Ladies:

I am counsel for Southwestern Energy Company (the "Borrower"), and have represented the Borrower and the Subsidiaries of the Borrower listed on Schedule 1 (the "Guarantors") in connection with its execution and delivery of an Amended and Restated Credit Agreement dated as of January 4, 2005 (the "Agreement") among the Borrower, the Lenders named therein, and JPMorgan Chase Bank, N.A., as Administrative Agent, and providing for Advances and Letters of Credit in an aggregate principal amount not exceeding $500,000,000 (or $550,000,000 if the option under Section 2.6.3 thereof has been exercised and become effective) at any one time outstanding. All capitalized terms used in this opinion and not otherwise defined herein shall have the meanings attributed to them in the Agreement.

I have examined the Borrower's and each Guarantor's **[describe constitutive documents of Borrower and Guarantors and appropriate evidence of authority to enter into the transaction]**, the Loan Documents and such other matters of fact and law which we deem necessary in order to render this opinion. Based upon the foregoing, it is our opinion that:

l. Each of the Borrower and its Subsidiaries is a corporation, partnership or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such concept applies to such entity) in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted.

2. The execution and delivery by the Borrower and each Guarantor of the Loan Documents to which it is a party and the performance by the Borrower and each Guarantor of its obligations thereunder have been duly authorized by proper corporate or limited liability company proceedings on the part of the Borrower and each Guarantor and will not:

(a) require any consent of the Borrower's or any Guarantor's shareholders or members (other than any such consent as has already been given and remains in full force and effect);

(b) violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on the Borrower or any of its Subsidiaries or (ii) the Borrower's or any Subsidiary's articles or certificate of incorporation, articles or certificate of organization, bylaws, or operating or other management agreement, as the case may be, or (iii) the provisions of any indenture, instrument or agreement to which the Borrower or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default thereunder; or

(c) result in, or require, the creation or imposition of any Lien in, of or on the Property of the Borrower or a Subsidiary pursuant to the terms of any indenture, instrument or agreement binding upon the Borrower or any of its Subsidiaries.

3. The Loan Documents to which the Borrower or any Guarantor is a party have been duly executed and delivered by the Borrower or such Guarantor, as the case may be, and constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower or such Guarantor, as the case may be, in accordance with their terms except to the extent the enforcement thereof may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally and subject also to the availability of equitable remedies if equitable remedies are sought.

4. Except for the litigation disclosed in Borrower's Form 10-K for the year ended December 31, 2003 and updated in the Borrower's most recent Form 10-Q, there is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the best of our knowledge after due inquiry, threatened against the Borrower or any of its Subsidiaries which, if adversely determined, could reasonably be expected to have a Material Adverse Effect.

5. No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the Borrower or any of its Subsidiaries, is required to be obtained by the Borrower or any of its Subsidiaries in connection with the execution and delivery of the Loan Documents, the borrowings under the Agreement, the payment and performance by the Borrower of the Obligations, or the legality, validity, binding effect or enforceability of any of the Loan Documents.

This opinion may be relied upon by the Administrative Agent, the Lenders and their participants, assignees and other transferees.

Very truly yours,

Southwestern Energy Company, an Arkansas corporation (the "Borrower"), promises to pay to the order of ____________________________________ (the "Lender") the aggregate unpaid principal amount of all Loans made by the Lender to the Borrower pursuant to Article II of the Agreement (as hereinafter defined), in immediately available funds at the main office of JPMorgan Chase Bank, N.A., as Administrative Agent, together with interest on the unpaid principal amount hereof at the rates and on the dates set forth in the Agreement. The Borrower shall pay the principal of and accrued and unpaid interest on the Loans in full on the Termination Date.

The Lender shall, and is hereby authorized to, record on the schedule attached hereto, or to otherwise record in accordance with its usual practice, the date and amount of each Loan and the date and amount of each principal payment hereunder.

This Note is one of the Notes issued pursuant to, and is entitled to the benefits of, the Amended and Restated Credit Agreement dated as of January 4, 2005 (as amended or otherwise modified from time to time, the "Agreement"), among the Borrower, the lenders party thereto, including the Lender, and JPMorgan Chase Bank, N.A., as Administrative Agent, to which Agreement reference is hereby made for a statement of the terms and conditions governing this Note, including the terms and conditions under which this Note may be prepaid or its maturity date accelerated.

If for any reason interest in excess of the Maximum Rate shall be deemed charged, required or permitted by any court of competent jurisdiction, the excess shall be applied as payment and reduction of the principal of indebtedness evidenced by this Note, and, if the principal amount has been paid in full, any remaining excess shall forthwith be paid to the Borrower.

FORM OF SUBSIDIARY GUARANTY

THIS AMENDED AND RESTATED SUBSIDIARY GUARANTY (this "Guaranty") is made as of January 4, 2005 by SOUTHWESTERN ENERGY SERVICES COMPANY, an Arkansas corporation, SOUTHWESTERN ENERGY PRODUCTION COMPANY, an Arkansas corporation, and SEECO, INC., an Arkansas corporation (together with any other entity that may from time to time become party hereto by signing a counterpart hereof, collectively the "Subsidiary Guarantors" and each a "Subsidiary Guarantor"), in favor of JPMorgan Chase Bank, N.A., a national banking association, as administrative agent (in such capacity, the "Agent").

WITNESSETH:

WHEREAS, Southwestern Energy Company, an Arkansas corporation (the "Company"), various financial institutions (the "Lenders") and the Agent have entered into an amended and restated credit agreement dated as of the date hereof (as the same may be amended, restated or otherwise modified from time to time, the "Credit Agreement"), providing, subject to the terms and conditions thereof, for extensions of credit to be made by various financial institutions to the Company;

WHEREAS, certain Subsidiaries of the Company executed and delivered a Subsidiary Guaranty dated as of January 2, 2004 (the "Existing Subsidiary Guaranty") to guarantee the obligations of the Company under a Credit Agreement dated as of January 2, 2004 among the Company, various financial institutions and JPMorgan Chase Bank, N.A. (as successor to Bank One, NA), as administrative agent;

WHEREAS, the execution and delivery of this Guaranty are conditions to the effectiveness of the Credit Agreement; and

WHEREAS, in consideration of the financial and other support that the Company has provided, and such financial and other support as the Company may in the future provide, to the Subsidiary Guarantors, and in order to induce the Lenders to grant extensions of credit under the Credit Agreement, and because each Subsidiary Guarantor has determined that executing this Guaranty is in its interest and to its financial benefit, each of the Subsidiary Guarantors is willing to guarantee the obligations of the Company under the Credit Agreement and the Notes and desires to amend and restate the Existing Subsidiary Guaranty as hereinafter set forth;

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Credit Agreement Definitions. Capitalized terms used herein but not defined herein shall have the respective meanings set forth in (or defined by reference in) the Credit Agreement.

SECTION 2. Representations and Warranties. Each Subsidiary Guarantor represents and warrants (which representations and warranties shall be deemed to have been renewed on each date on which a Lender makes a Loan to the Company) that:

(a) It is a corporation, partnership or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such concept applies to such entity) in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted.

(b) It has the power and authority and legal right to execute and deliver this Guaranty and to perform its obligations hereunder. The execution and delivery by it of this Guaranty and the performance of its obligations hereunder have been duly authorized by proper organizational proceedings, and this Guaranty constitutes a legal, valid and binding obligation of such Subsidiary Guarantor enforceable against it in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally.

(c) Neither the execution and delivery by it of this Guaranty, nor the consummation of the transactions herein contemplated, nor compliance with the provisions hereof will violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on it or any of its Subsidiaries or (ii) its articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, bylaws, or operating or other management agreement, as the case may be, or (iii) the provisions of any indenture, instrument or agreement to which it or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default thereunder, or result in, or require, the creation or imposition of any Lien in, of or on the Property of such Subsidiary Guarantor or a Subsidiary thereof pursuant to the terms of any such indenture, instrument or agreement. No order, consent, adjudication, approval, license, authorization or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by it or any of its Subsidiaries, is required to be obtained by it or any of its Subsidiaries in connection with the execution and delivery of this Guaranty or the performance by it of its obligations hereunder or the legality, validity, binding effect or enforceability of this Guaranty.

SECTION 3. The Guaranty. Subject to Section 9 hereof, each Subsidiary Guarantor hereby absolutely and unconditionally guarantees, as primary obligor and not as merely surety, the full and punctual payment (whether at stated maturity, upon acceleration or early termination or otherwise, and at all times thereafter) and performance of the unpaid principal of and accrued and unpaid interest on the Loans, all accrued and unpaid fees and all expenses, reimbursements, indemnities and other obligations of the Company to the Lender or any other indemnified party arising under the Loan Documents, including without limitation any such obligations incurred or accrued during the pendency of any bankruptcy, insolvency, receivership or similar proceeding, whether or not allowed or allowable in such proceeding (collectively, subject to the provisions of Section 9 hereof, the "Guaranteed Obligations"). Upon failure by the Company to pay punctually any such amount, each Subsidiary Guarantor agrees that it shall forthwith on written demand pay to the Agent the amount not so paid at the place and in the manner specified in the Credit Agreement. This Guaranty is a guaranty of payment and not of collection. Each Subsidiary Guarantor waives any right to require the Agent or any Lender to sue the Company, any other guarantor, or any other person obligated for all or any part of the Guaranteed Obligations.

SECTION 4. Guaranty Unconditional. Subject to Section 9 hereof, the obligations of each Subsidiary Guarantor hereunder shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by:

(i) any extension, renewal, settlement, compromise, waiver or release in respect of any of the Guaranteed Obligations, by operation of law or otherwise, or any obligation of any other guarantor of any of the Guaranteed Obligations, or any default, failure or delay, willful or otherwise, in the payment or performance of the Guaranteed Obligations;

(ii) any modification or amendment of or supplement to the Credit Agreement or the Notes;

(iii) #9; any release, nonperfection or invalidity of any direct or indirect security for any obligation of the Company under the Credit Agreement or the Notes or any obligation of any other guarantor of any of the Guaranteed Obligations;

(iv) any change in the corporate existence, structure or ownership of the Company or any other guarantor of any of the Guaranteed Obligations, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Company or any other guarantor of the Guaranteed Obligations, or the assets of any of the foregoing, or any resulting release or discharge of any obligation of the Company or any other guarantor of any of the Guaranteed Obligations;

(v) the existence of any claim, setoff or other right which such Subsidiary Guarantor may have at any time against the Company, any other guarantor of any of the Guaranteed Obligations, the Agent, any Lender or any other Person, whether in connection herewith or any unrelated transaction;

(vi) any invalidity or unenforceability relating to or against the Company, or any other guarantor of any of the Guaranteed Obligations, for any reason related to the Credit Agreement or the Notes, or any provision of applicable law or regulation purporting to prohibit the payment by the Company, or any other guarantor of the Guaranteed Obligations, of the principal of or interest on the Notes or any other amount payable by the Company under the Credit Agreement or the Notes; or

(vii) any other act or omission to act or delay of any kind by the Company, any other guarantor of the Guaranteed Obligations, the Agent, any Lender or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of such Subsidiary Guarantor's obligations hereunder.

SECTION 5. Discharge Only Upon Payment In Full: Reinstatement In Certain Circumstances. Each Subsidiary Guarantor's obligations hereunder shall remain in full force and effect until all Guaranteed Obligations shall have been indefeasibly paid in full and the Commitment shall have terminated or expired. If at any time any payment of the principal of or interest on the Notes or any other amount payable by the Company under the Credit Agreement, or by any Subsidiary Guarantor hereunder, is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Subsidiary Guarantor's obligations hereunder with respect to such payment shall be reinstated as though such payment had been due but not made at such time.

SECTION 6. Waivers. Each Subsidiary Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and, to the fullest extent permitted by law, any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Company, any other guarantor of any of the Guaranteed Obligations or any other Person.

SECTION 7. Subrogation. Each Subsidiary Guarantor hereby agrees not to assert any right, claim or cause of action, including, without limitation, a claim for subrogation, reimbursement, indemnification or otherwise, against the Company arising out of or by reason of this Guaranty or the obligations hereunder, including, without limitation, the payment or securing or purchasing of any of the Guaranteed Obligations by any of the Subsidiary Guarantors, unless and until the Guaranteed Obligations are indefeasibly paid in full and the Commitment has terminated.

SECTION 8. Stay of Acceleration. If acceleration of the time for payment of any of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of the Credit Agreement or the Notes shall nonetheless be payable by each of the Subsidiary Guarantors hereunder forthwith on demand by the Agent.

SECTION 9. Limitation on Obligations.

(a) The provisions of this Guaranty are severable, and in any action or proceeding involving any state corporate law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Subsidiary Guarantor under this Guaranty would otherwise be held or determined to be avoidable, invalid or unenforceable on account of the amount of such Subsidiary Guarantor's liability under this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the amount of such liability shall, without any further action by any Subsidiary Guarantor, the Agent or any Lender, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding (such highest amount determined hereunder being the relevant Subsidiary Guarantor's "Maximum Liability"). This Section 9(a) with respect to the Maximum Liability of the Subsidiary Guarantors is intended solely to preserve the rights of the Agent and the Lenders hereunder to the maximum extent not subject to avoidance under applicable law, and neither a Subsidiary Guarantor nor any other Person shall have any right or claim under this Section 9(a) with respect to the Maximum Liability, except to the extent necessary so that the obligations of each Subsidiary Guarantor hereunder shall not be rendered voidable under applicable law.

(b) Each Subsidiary Guarantor agrees that the Guaranteed Obligations may at any time and from time to time exceed the Maximum Liability of such Subsidiary Guarantor, and may exceed the aggregate Maximum Liability of all other Subsidiary Guarantors, without impairing this Guaranty or affecting the rights and remedies of the Agent hereunder. Nothing in this Section 9(b) shall be construed to increase any Subsidiary Guarantor's obligations hereunder beyond its Maximum Liability.

(c) If any Subsidiary Guarantor (a "Paying Subsidiary Guarantor") shall make any payment or payments under this Guaranty, each other Subsidiary Guarantor (each a "Non-Paying Subsidiary Guarantor") shall contribute to such Paying Subsidiary Guarantor an amount equal to such Non-Paying Subsidiary Guarantor's "Pro Rata Share" of such payment or payments made, or losses suffered, by such Paying Subsidiary Guarantor. For the purposes hereof, each Non-Paying Subsidiary Guarantor's "Pro Rata Share" with respect to any such payment or loss by a Paying Subsidiary Guarantor shall be determined as of the date on which such payment or loss was made by reference to the ratio of (i) such Non-Paying Subsidiary Guarantor's Maximum Liability as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder) or, if such Non-Paying Subsidiary Guarantor's Maximum Liability has not been determined, the aggregate amount of all monies received by such Non-Paying Subsidiary Guarantor from the Company after the date hereof (whether by loan, capital infusion or by other means) to (ii) the sum of the Maximum Liabilities (which may be greater than the amount of Guaranteed Obligations) of all Subsidiary Guarantors hereunder (including such Paying Subsidiary Guarantor) as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder), or to the extent that a Maximum Liability has not been determined for any Subsidiary Guarantor, the aggregate amount of all monies received by such Subsidiary Guarantor from the Company after the date hereof (whether by loan, capital infusion or by other means). Nothing in this Section 9(c) shall affect any Subsidiary Guarantor's several liability for the entire amount of the Guaranteed Obligations (up to such Subsidiary Guarantor's Maximum Liability). Each Subsidiary Guarantor covenants and agrees that its right to receive any contribution under this Guaranty from a Non-Paying Subsidiary Guarantor shall be subordinate and junior in right of payment to all the Guaranteed Obligations. The provisions of this Section 9(c) are for the benefit of the Agent, the Lenders and the Subsidiary Guarantors and may be enforced by any of them in accordance with the terms hereof.

SECTION 10. Application of Payments. All payments received by the Agent hereunder shall be applied by the Agent to payment of the Guaranteed Obligations in the following order unless a court of competent jurisdiction shall otherwise direct:

(a) FIRST, to payment of all costs and expenses of the Agent incurred in connection with the collection and enforcement of the Guaranteed Obligations;

(b) SECOND, to payment of that portion of the Guaranteed Obligations constituting accrued and unpaid interest and fees; and

(c) THIRD, to payment of any other Guaranteed Obligations.

SECTION 11. Notices. All notices, requests and other communications to any party hereunder shall be given or made by facsimile or other writing and faxed, mailed or delivered to the intended recipient at its address or facsimile number set forth under its name on Schedule I hereto or such other address or facsimile number as such party may hereafter specify for such purpose by notice to the Agent in accordance with the provisions of Section 8.5 of the Credit Agreement. Except as otherwise provided in this Guaranty, all such communications shall be deemed to have been duly given when transmitted by facsimile, or personally delivered or, in the case of a mailed notice sent by certified mail return-receipt requested, on the date set forth on the receipt (provided that any refusal to accept any such notice shall be deemed to be notice thereof as of the time of any such refusal), in each case given or addressed as aforesaid.

SECTION 12. No Waivers. No failure or delay by the Agent in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies provided in this Guaranty, the Credit Agreement and the Notes shall be cumulative and not exclusive of any rights or remedies provided by law.

SECTION 13. No Duty to Advise. Each Subsidiary Guarantor assumes all responsibility for being and keeping itself informed of the Company's financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks that such Subsidiary Guarantor assumes and incurs under this Guaranty, and agrees that the Agent does not have any duty to advise such Subsidiary Guarantor of information known to it regarding those circumstances or risks.

SECTION 14. Successors and Assigns. This Guaranty is for the benefit of the Agent, the Lenders and their respective successors and permitted assigns and in the event of an assignment of any amounts payable under the Credit Agreement or the Notes, the rights hereunder, to the extent applicable to the indebtedness so assigned, shall be transferred with such indebtedness. This Guaranty shall be binding upon each Subsidiary Guarantor and its successors.

SECTION 15. Changes in Writing. Neither this Guaranty nor any provision hereof may be changed, waived, discharged or terminated orally, but only in writing signed by each of the Subsidiary Guarantors and the Agent.

SECTION 16. Costs of Enforcement. Each Subsidiary Guarantor agrees to pay all costs and expenses, including, without limitation, all court costs and attorneys' fees and expenses, paid or incurred by the Agent in endeavoring to collect all or any part of the Guaranteed Obligations from, or in prosecuting any action against, the Company, such Subsidiary Guarantor or any other guarantor of all or any part of the Guaranteed Obligations.

SECTION 17. GOVERNING LAW; SUBMISSION TO JURISDICTION; WAIVER OF JURY TRIAL. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF ILLINOIS. EACH SUBSIDIARY GUARANTOR HEREBY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS AND OF ANY ILLINOIS STATE COURT SITTING IN CHICAGO, ILLINOIS FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO THIS GUARANTY (INCLUDING, WITHOUT LIMITATION, THE CREDIT AGREEMENT OR THE NOTES) OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH SUBSIDIARY GUARANTOR IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. EACH SUBSIDIARY GUARANTOR, AND THE AGENT AND EACH LENDER BY ACCEPTING THE BENEFITS OF THIS GUARANTY, HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE TRANSACTIONS CONTEMPLATED HEREBY.

SECTION 18. Taxes. etc. All payments required to be made by any of the Subsidiary Guarantors hereunder shall be made without setoff or counterclaim and free and clear of and without deduction or withholding for or on account of, any present or future taxes, levies, imposts, duties or other charges of whatsoever nature imposed by any government or any political or taxing authority thereof (but excluding Excluded Taxes), provided, however, that if any Subsidiary Guarantor is required by law to make such deduction or withholding, such Subsidiary Guarantor shall forthwith (i) pay to the Agent or the applicable Lender such additional amount as results in the net amount received by the Agent equaling the full amount which would have been received by the Agent or such Lender had no such deduction or withholding been made, (ii) pay the full amount deducted to the relevant authority in accordance with applicable law, and (iii) furnish to the Agent or such Lender certified copies of official receipts evidencing payment of such withholding taxes within 30 days after such payment is made.

IN WITNESS WHEREOF, each Subsidiary Guarantor has caused this Guaranty to be duly executed by its authorized officer as of the day and year first above written.
