(a) The Revolving Advances (together with the Swingline Advances, a "Class" of Loan) shall, at the option of the Borrower and subject to the terms and conditions of this Agreement, be either a Base Rate Advance or Eurodollar Rate Advance (each, a "Type" of Advance). The Swingline Advances shall be made and maintained as LIBOR Market Index Rate Advances at all times.

21


(b) In order to make a Borrowing (other than (w) Borrowings of Swingline Advances, which shall be made pursuant to Section 2.2(c), (y) Borrowings for the purpose of repaying Refunded Swingline Advances, which shall be made pursuant to Section 2.2(d), or (z) conversions of outstanding Advances made pursuant to Section 2.11), the Borrower will give the Agent written notice not later than 11:00 a.m. (i) on the third Business Day prior to the date of the proposed Borrowing, in the case of a Borrowing comprised of Eurodollar Rate Advances and (ii) not later than 10:00 a.m. on the date of the proposed Borrowing, in the case of a Borrowing comprised of Base Rate Advances. Each such notice of a Borrowing (a "Notice of Borrowing") shall be by facsimile or email (in accordance with procedures prescribed by the Agent), in substantially the form of Exhibit 2.2(b) hereto, specifying therein the requested (A) date of such Borrowing, (B) Type of Advances comprising such Borrowing, (C) aggregate amount of such Borrowing and (D) in the case of a Borrowing comprised of Eurodollar Rate Advances, the initial Interest Period for each such Advance. Each Lender shall, before (x) 12:00 noon on the date of such Borrowing, in the case of a Borrowing comprised of Eurodollar Rate Advances, and (y) 1:00 p.m. on the date of such Borrowing, in the case of a Borrowing comprised of Base Rate Advances, make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.2, in same day funds, such Lender's Percentage of such Borrowing. After the Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will promptly make such funds available to the Borrower by means of a credit or wire transfer to the account specified in writing by the Borrower.

(c) In order to make a Borrowing of a Swingline Advance, the Borrower will give the Agent (and the Swingline Lender, if the Swingline Lender is not also the Agent) written notice not later than 2:00 p.m. on the date of such Borrowing. Each such notice of a Borrowing (a "Notice of Swingline Borrowing") shall be by facsimile or email (in accordance with procedures prescribed by the Agent), in substantially the form of Exhibit 2.2(c) hereto, specifying therein the requested (A) date of such Borrowing, and (B) aggregate amount of such Swingline Advance to be made pursuant to such Borrowing (which shall not be less than $1,000,000 and, if greater, shall be in an integral multiple of $500,000 in excess thereof (or, if less, in the amount of the Unutilized Swingline Commitment)). Not later than 4:00 p.m. on the date of such Borrowing, the Swingline Lender will make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.2, in same day funds, an amount equal to the amount of the requested Swingline Advance. After the Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will promptly make such funds available to the Borrower by means of a credit or wire transfer to the account specified in writing by the Borrower.

(d) With respect to any outstanding Swingline Advances, the Swingline Lender may at any time (whether or not any Unmatured Default or Event of Default has occurred and is continuing) in its sole and absolute discretion, and is hereby authorized and empowered by the Borrower to, cause a Revolving Advance to be made for the purpose of repaying such Swingline Advances by delivering to the Agent (if the Agent is not also the Swingline Lender) and each

22


other Lender (on behalf of, and with a copy to, the Borrower), not later than 11:00 a.m. one Business Day prior to the proposed date of such Borrowing therefor, a notice (which shall be deemed to be a Notice of Borrowing given by the Borrower) requesting the Lenders to make Revolving Advances (which shall be made initially as Base Rate Advances) on such date of Borrowing in an aggregate amount equal to the amount of such Swingline Advances (the "Refunded Swingline Advances") outstanding on the date such notice is given that the Swingline Lender requests to be repaid. Not later than 1:00 p.m. on the requested date of such Borrowing, each Lender (other than the Swingline Lender) will make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.2, in same day funds, such Lender's Percentage of such Borrowing. To the extent the Lenders have made such amounts available to the Agent as provided hereinabove, the Agent will make the aggregate of such amounts available to the Swingline Lender in like funds as received by the Agent, which shall apply such amounts in repayment of the Refunded Swingline Advances. Notwithstanding any provision of this Agreement to the contrary, on the relevant date of such Borrowing, the Refunded Swingline Advances (including the Swingline Lender's Percentage thereof, in its capacity as a Lender) shall be deemed to be repaid with the proceeds of the Revolving Advances made as provided above (including a Revolving Advance deemed to have been made by the Swingline Lender), and such Refunded Swingline Advances deemed to be so repaid shall no longer be outstanding as Swingline Advances but shall be outstanding as Revolving Advances. If any portion of any such amount repaid (or deemed to be repaid) to the Swingline Lender shall be recovered by or on behalf of the Borrower from the Swingline Lender in any bankruptcy, insolvency or similar proceeding or otherwise, the loss of the amount so recovered shall be shared ratably among all the Lenders in the manner contemplated by Section 2.18.

(e) If, as a result of any bankruptcy, insolvency or similar proceeding with respect to the Borrower, Revolving Advances are not made pursuant to Section 2.2(d) in an amount sufficient to repay any amounts owed to the Swingline Lender in respect of any outstanding Swingline Advances, or if the Swingline Lender is otherwise precluded for any reason from giving a notice on behalf of the Borrower as provided for hereinabove, the Swingline Lender shall be deemed to have sold without recourse, representation or warranty (except for the absence of Liens thereon created, incurred or suffered to exist by, through or under the Swingline Lender), and each Lender shall be deemed to have purchased and hereby agrees to purchase, a participation in such outstanding Swingline Advances in an amount equal to its Percentage of the unpaid amount thereof together with accrued interest thereon. Upon one Business Day's prior notice from the Swingline Lender, each Lender (other than the Swingline Lender) will make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.2, in same day funds, such Lender's respective participation. To the extent the Lenders have made such amounts available to the Agent as provided hereinabove, the Agent will make the aggregate of such amounts available to the Swingline Lender in like funds as received by the Agent. In the event any such Lender fails to make available to the Agent the amount of such Lender's participation as provided in this Section 2.2(e), the Swingline Lender shall be entitled to recover such amount on demand from such Lender, together with interest thereon for each day from the date such amount is required to be made available for the account of the Swingline Lender until the date such amount is made available to the Swingline Lender at the Federal Funds Rate for the first three Business Days and thereafter at the Applicable Rate for Base Rate Advances. Promptly following its receipt of any payment by or on behalf of the Borrower in respect of a Swingline Advance, the Swingline Lender will pay to each Lender that has acquired a participation therein such Lender's ratable share of such payment.

23


(f) Notwithstanding any provision of this Agreement to the contrary, the obligation of each Lender (other than the Swingline Lender) to make Revolving Advances for the purpose of repaying any Refunded Swingline Advances pursuant to Section 2.2(d) and each such Lender's obligation to purchase a participation in any unpaid Swingline Advances pursuant to Section 2.2(e) shall be absolute and unconditional and shall not be affected by any circumstance or event whatsoever, including, without limitation, (i) any set-off, counterclaim, recoupment, defense or other right that such Lender may have against the Swingline Lender, the Agent, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or continuance of any Unmatured Default or Event of Default, (iii) the failure of the amount of such Borrowing of Revolving Advances to meet the minimum Borrowing amount specified in Section 2.1(a), or (iv) the failure of any conditions set forth in Section 3.2 or elsewhere herein to be satisfied.

(g) Each Notice of Borrowing and Notice of Swingline Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Eurodollar Rate Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

Section 2.3 Funding Reliance.

(a) Unless the Agent shall have received notice from a Lender prior to the time of any Borrowing that such Lender will not make available to the Agent such Lender's Advance as part of such Borrowing, the Agent may assume that such Lender has made such Advance available to the Agent on the time of such Borrowing in accordance with Section 2.2 and the Agent may, in reliance upon such assumption, make available to the Borrower on such time a corresponding amount. If and to the extent that such Lender shall not have so made such Advance available to the Agent, such Lender and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the time such amount is made available to the Borrower until the time such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Lender's Advance as part of such Borrowing for purposes of this Agreement.

(b) The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

Section 2.4 Letters of Credit.

(a) Subject to the terms and conditions hereof, so long as no Unmatured Default or Event of Default has occurred and is continuing, each Letter of Credit shall be issued (or the stated maturity thereof extended or terms thereof modified or amended) on not less than two Business Days' prior notice thereof by delivery of a Request for Issuance to the Agent and the applicable LC Issuing Bank substantially in the form attached hereto in Exhibit 2.4. Each Request for Issuance shall specify a statement of drawing conditions applicable to such Letter of Credit, and if such Request for Issuance relates to an amendment or modification of a Letter of Credit, it shall be accompanied by the consent of the beneficiary of the Letter of Credit thereto. The expiry of such Letter of Credit shall be no later than the earlier of (i) five Business Days' prior to the Termination Date and (ii) one year after its date of issuance; provided, however, that a Letter of Credit may, if requested by the Borrower, provide by its terms, and on terms acceptable to the applicable LC Issuing Bank, for renewal for successive periods of one year or less (but not beyond the date five Business Days prior to the applicable Termination Date), unless and until such LC Issuing Bank shall have delivered a notice of nonrenewal to the beneficiary of such Letter of Credit. Each Request for Issuance shall be irrevocable unless modified or rescinded by the Borrower not less than one day prior to the proposed date of issuance (or effectiveness) specified therein. Not later than 12:00 noon on the proposed date of issuance (or effectiveness) specified in such Request for Issuance, and upon fulfillment of the applicable conditions precedent and the other requirements set forth herein, the applicable LC Issuing Bank shall issue (or extend, amend or modify) such Letter of Credit and provide notice and a copy thereof to the Agent, which shall promptly furnish copies thereof to the Lenders.

(b) No Letter of Credit shall be requested or issued hereunder if, (i) after the issuance thereof, (A) the Outstanding Credits would exceed the Aggregate Commitments (as reduced by an amount equal to the difference of (x) the Commitment of any Defaulting Lender minus (y) the principal amount of such Defaulting Lenders' funded Outstanding Credits), (B) the LC Outstandings would exceed the LC Subcommitment or (C) the aggregate Credit Exposure would exceed the Aggregate Commitment, or (ii) any Lender is at such time a Designated Lender hereunder, unless the applicable LC Issuing Bank has entered into satisfactory arrangements, including, without limitation, the posting of Cash Collateral, with the Borrower or such Lender to eliminate such LC Issuing Bank's Fronting Exposure with respect to such Lender.

(c) The Borrower hereby agrees to pay to the Agent for the account of the applicable LC Issuing Bank and, if they shall have purchased participations in the reimbursement obligations of the Borrower pursuant to Section 2.4(d), the Lenders, on demand made by the applicable LC Issuing Bank to the Borrower, on and after each date on which such LC Issuing Bank shall pay any amount under any Letter of Credit issued by such LC Issuing Bank, a sum equal to the amount so paid plus interest on such amount from the date so paid by such LC Issuing Bank until repayment to such LC Issuing Bank in full at a fluctuating interest rate per annum equal to the interest rate applicable to Base Rate Advances plus, if any amount paid by such LC Issuing Bank under a Letter of Credit is not reimbursed by the Borrower within three Business Days, 2%.

25


(d) Immediately upon the issuance of any Letter of Credit, the applicable LC Issuing Bank shall be deemed to have sold and transferred to each Lender, and each Lender shall be deemed irrevocably and unconditionally to have purchased and received from such LC Issuing Bank, without recourse or warranty, an undivided interest and participation, pro rata (based on such Lender's Percentage), in such Letter of Credit, each drawing made thereunder and the obligations of the Borrower under this Agreement with respect thereto (other than the fees payable by the Borrower to such LC Issuing Bank). If the applicable LC Issuing Bank shall not have been reimbursed in full for any payment made by such LC Issuing Bank under a Letter of Credit issued by such LC Issuing Bank on the date of such payment, such LC Issuing Bank shall give the Agent and each Lender prompt notice thereof (an "LC Payment Notice") no later than 12:00 noon on the Business Day immediately succeeding the date of such payment by such LC Issuing Bank. Each Lender severally agrees, absolutely and unconditionally, to pay to the Agent for the account of the applicable LC Issuing Bank an amount equal to such Lender's Percentage of such unreimbursed amount paid by such LC Issuing Bank, plus interest on such amount at a rate per annum equal to the Federal Funds Rate from the date of the payment by such LC Issuing Bank to the date of payment to such LC Issuing Bank by such Lender. Each such payment by a Lender shall be made not later than 3:00 p.m. on the later to occur of (i) the Business Day immediately following the date of such payment by the applicable LC Issuing Bank and (ii) the Business Day on which such Lender shall have received an LC Payment Notice from such LC Issuing Bank. Each Lender's obligation to make each such payment to the Agent for the account of the applicable LC Issuing Bank shall be several and shall not be affected by the occurrence or continuance of an Unmatured Default or Event of Default or the failure of any other Lender to make any payment under this Section 2.4(d) or the failure of such LC Issuing Bank to provide the LC Payment Notice by 12:00 noon on the Business Day immediately succeeding the date of payment under a Letter of Credit by such LC Issuing Bank. Upon any change in the Commitment of any Lender, with respect to all outstanding Letters of Credit and reimbursement obligations there shall be an automatic adjustment to the participations pursuant to this Section 2.4(d) to reflect the new Percentages of the Lenders.

(e) The failure of any Lender to make any payment to the Agent for the account of the applicable LC Issuing Bank in accordance with Section 2.4(d) shall not relieve any other Lender of its obligation to make payment, but no Lender shall be responsible for the failure of any other Lender. If any Lender (a "Non-Performing Lender") shall fail to make any payment to the Agent for the account of the applicable LC Issuing Bank in accordance with Section 2.4(d) within five Business Days after the LC Payment Notice relating thereto, then, for so long as such failure shall continue, such LC Issuing Bank shall be deemed, for purposes of Section 8.1 and Article VI hereof, to be a Lender owed a Borrowing in an amount equal to the outstanding principal amount due and payable by such Non-Performing Lender to the Agent for the account of such LC Issuing Bank pursuant to Section 2.4(d). Any Non-Performing Lender and the Borrower (without waiving any claim against such Lender for such Lender's failure to purchase a participation in the reimbursement obligations of the Borrower under Section 2.4(d)) severally agree to pay to the Agent for the account of the applicable LC Issuing Bank forthwith on demand such amount, together with interest thereon for each day from the date such Lender would have purchased its participation had it complied with the requirements of Section 2.4(d) until the date such amount is paid to the Agent at (i) in the case of the Borrower, the interest rate applicable at the time to Base Rate Advances and (ii) in the case of such Lender, the rate applicable to Base Rate Advances plus 1%.

26


(f) The payment obligations of each Lender under Section 2.4(d) and of the Borrower under this Agreement in respect of any payment under any Letter of Credit by any LC Issuing Bank shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances:

(i) any lack of validity or enforceability of this Agreement, any other Loan Document or any other agreement or instrument relating thereto or to such Letter of Credit;

(ii) any amendment or waiver of, or any consent to departure from, the terms of this Agreement, any other Loan Document or such Letter of Credit;

(iii) the existence of any claim, set-off, defense or other right which the Borrower may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), any LC Issuing Bank, the Agent, any Lender or any other Person, whether in connection with this Agreement, the transactions contemplated hereby, thereby or by such Letter of Credit, or any unrelated transaction;

(iv) any statement or any other document presented under such Letter of Credit reasonably proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(v) payment in good faith by any LC Issuing Bank under the Letter of Credit issued by such LC Issuing Bank against presentation of a draft or certificate that does not comply with the terms of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

(g) The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit. Neither the LC Issuing Banks, the Lenders nor any of their Related Parties shall be liable or responsible for (i) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (iii) payment by the applicable LC Issuing Bank against presentation of documents that do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit; or (iv) any other circumstances whatsoever in making or failing to make payment under such Letter of Credit. Notwithstanding any provision to the contrary contained in any Loan Document, the Borrower and each Lender shall have the right to bring suit against any LC Issuing Bank, and such LC Issuing Bank shall be liable to the Borrower and any Lender, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender which the Borrower or such Lender proves were caused by such LC Issuing Bank's willful misconduct or gross negligence, including, in the case of the Borrower, such LC Issuing Bank's willful failure to make timely payment under such

27


Letter of Credit following the presentation to it by the beneficiary thereof of a draft and accompanying certificate(s) that strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, each LC Issuing Bank may accept sight drafts and accompanying certificates presented under the Letter of Credit issued by such LC Issuing Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and payment against such documents shall not constitute willful misconduct or gross negligence by such LC Issuing Bank. Notwithstanding the foregoing, no Lender shall be obligated to indemnify the Borrower for damages caused by any LC Issuing Bank's willful misconduct or gross negligence.

(h) If any Letter of Credit contains a provision pursuant to which it is deemed to be automatically renewed unless notice of termination of such Letter of Credit is given by the applicable LC Issuing Bank, such LC Issuing Bank shall timely give notice of termination if (i) as of close of business on the seventeenth day prior to the last day upon which the LC Issuing Bank's notice of termination may be given to the beneficiaries of such Letter of Credit, the LC Issuing Bank has received a notice of termination from the Borrower or a notice from the Agent that the conditions to issuance of such Letter of Credit have not been satisfied or (ii) the renewed Letter of Credit would have a term not permitted by Section 2.4(a).

(i) If (i) as of the Termination Date, any Letter of Credit may for any reason remain outstanding, or (ii) at any time, the aggregate Outstanding Credits shall exceed the Aggregate Commitment (after giving effect to any concurrent termination or reduction thereof), the Borrower shall (A) deliver to the Agent as cash collateral an amount in cash equal to the aggregate LC Outstandings (whether or not any beneficiary under any Letter of Credit shall have drawn or be entitled at such time to draw thereunder) or, in the case of clause (ii) above, an amount in cash equal to such excess or (B) shall make some other arrangements to provide credit support for such Letters of Credit reasonably satisfactory to the Agent and the applicable LC Issuing Bank. The Agent shall deposit such cash in a special collateral account of the Borrower pursuant to arrangements satisfactory to the Agent (such account, the "Cash Collateral Account") for the benefit of the Agent, the LC Issuing Banks and the Lenders. Such Cash Collateral Account shall at all times be free and clear of all rights or claims of third parties. The Cash Collateral Account shall be maintained with the Agent in the name of, and under the sole dominion and control of, the Agent, and amounts deposited in the Cash Collateral Account shall bear interest at a rate equal to the rate generally offered by Wells Fargo for deposits equal to the amount deposited by the Borrower in the Cash Collateral Account, for a term to be determined by the Agent, in its sole discretion. The Borrower hereby grants to the Agent for the benefit of the LC Issuing Banks and the Lenders a Lien in and hereby assigns to the Agent for the benefit of LC Issuing Banks and the Lenders all of its right, title and interest in, the Cash Collateral Account and all funds from time to time on deposit therein to secure its reimbursement obligations in respect of Letters of Credit. If any drawings then outstanding or thereafter made are not reimbursed in full immediately upon demand or, in the case of subsequent drawings, upon being made, then, in any such event, the Agent may apply the amounts then on deposit in the Cash Collateral Account, toward the payment in full of any of the obligations as and when such obligations shall become due and payable. Any amounts remaining in the Cash Collateral Account (including interest) after the expiration of all Letters of Credit and reimbursement in full of the LC Issuing Banks for all of its obligations thereunder shall be held by the Agent, for the benefit of the Borrower, to be applied against the Outstanding Credits, together with expenses

28


related thereto and accrued interest thereon, in such order and manner as the Agent may direct. If the Borrower is required to provide cash collateral in the case of clause (ii) above, such amount (including interest), to the extent not applied as aforesaid, shall be returned to the Borrower on demand, provided that after giving effect to such return (i) the aggregate Outstanding Credits would not exceed the Aggregate Commitment at such time and (ii) no Unmatured Default or Event of Default shall have occurred and be continuing at such time.

Section 2.5 Fees.

(a) To Wells Fargo Securities, LLC and J.P. Morgan Securities LLC, for their own respective accounts, on the Amendment Effective Date, the fees required under the Active Joint Arrangers Fee Letter to be paid to them on the Amendment Effective Date, in the amounts due and payable on such date as required by the terms thereof;

(b) The Borrower agrees to pay to the Agent for the account of each Lender the Facility Fee, from the date hereof, in the case of each Bank, and from the effective date specified in the Lender Assignment pursuant to which it became a Lender, in the case of each other Lender, until the later of the Termination Date and the date all Outstanding Credits are paid in full, payable quarterly in arrears on the last day of each March, June, September and December during the term of such Lender's Commitment, commencing March 31, 2012, and on the later of the Termination Date and the date all Advances are paid in full; provided, however, that any Defaulting Lender shall only be entitled to a Facility Fee as provided in Section 2.21(a)(iii).

In addition, the Borrower shall pay to each LC Issuing Bank such fees for the issuance and maintenance of Letters of Credit issued by such LC Issuing Bank and for drawings thereunder as may be separately agreed between the Borrower and the LC Issuing Bank.

(a) The Borrower shall have the right, upon at least three Business Days' notice to the Agent, to terminate in whole or reduce ratably in part the unused portions of the Aggregate Commitment; provided that the Aggregate Commitment shall not be reduced to an amount which is less than the aggregate principal amount of the Outstanding Credits; and provided, further, that each partial reduction shall be in a minimum amount of $10,000,000 or any whole multiple of $1,000,000 in excess thereof.

(b) On the Termination Date, the Aggregate Commitment shall be automatically reduced to zero.

(c) Any termination or reduction of the Aggregate Commitment under this Section 2.6 shall be irrevocable, and the Aggregate Commitment shall not thereafter be reinstated.

(d) On any date prior to the Termination Date, the Borrower may on one or more occasions increase the Aggregate Commitment (any such increase, a "Commitment Increase") by an amount not less than $25,000,000, or, if greater, an integral multiple of $1,000,000 in excess thereof by designating either one or more of the existing Lenders (each of which, in its sole discretion, may determine whether and to what degree it may participate in such Commitment Increase) or one or more other Eligible Assignees reasonably acceptable to the Agent that at the time agree, in the case of any such existing Lender, to increase its Commitment (an "Increasing Lender") and, in the case of any such Eligible Assignee (an "Additional Lender"), to become a party to this Agreement; provided that after giving effect to any such increase, the Aggregate Commitment shall not exceed $400,000,000 and the aggregate amount of all Commitment Increases shall not exceed $100,000,000.

(i) The sum of the increases in the Commitments of the Increasing Lenders pursuant to this Section 2.6(d) plus the Commitments of the Additional Lenders upon giving effect to the Commitment Increase shall not in the aggregate exceed the amount of the Commitment Increase. The Borrower shall provide prompt notice of any proposed Commitment Increase pursuant to this Section 2.6(d) to the Agent, which shall promptly provide a copy of such notice to the Lenders;

(ii) Any Commitment Increase shall become effective upon (A) the receipt by the Agent of (1) an agreement in form and substance satisfactory to the Agent signed by the Borrower, each Increasing Lender and each Additional Lender, setting forth the new Commitment of each such Lender and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all the terms and provisions hereof binding upon each Lender, and (2) certified copies of the Commitment Increase Approvals and such opinions of counsel for the Borrower with respect to the Commitment Increase as the Agent may reasonably request, (B) the funding by each Lender of the Advance(s) to be made by each such Lender described in paragraph (iii) below and (C) receipt by the Agent of a certificate (the statements contained in which shall be true) of a duly authorized officer of the Borrower stating that both before and after giving effect to such Commitment Increase (1) no Unmatured Default or Event of Default has occurred and is continuing, (2) all representations and warranties made by

30


the Borrower in this Agreement are true and correct in all material respects, or if any such representation is qualified as to materiality, true and correct in all respects, and (3) all Commitment Increase Approvals have been obtained and are in full force and effect.

(iii) Upon the effective date of any Commitment Increase, to the extent necessary to keep the outstanding Advances ratable in the event of any non-ratable increase in Aggregate Commitment, (A) all then outstanding Eurodollar Rate Advances (the "Initial Advances") shall automatically be Converted into Base Rate Advances, (B) immediately after the effectiveness of the Commitment Increase, the Borrower shall, if it so requests, Convert such Base Rate Advances into Eurodollar Rate Advances (the "Subsequent Advances") in an aggregate principal amount equal to the aggregate principal amount of the Initial Advances and of the Types and for the Interest Periods specified in a Notice of Conversion delivered to the Agent in accordance with Section 2.11, (C) each Lender shall pay to the Agent in immediately available funds an amount equal to the difference, if positive, between (y) such Lender's Percentage (calculated after giving effect to the Commitment Increase) of the Subsequent Advances and (z) such Lender's Percentage (calculated without giving effect to the Commitment Increase) of the Initial Advances, (D) after the Agent receives the funds specified in clause (C) above, the Agent shall pay to each Lender the portion of such funds equal to the difference, if positive, between (y) such Lender's Percentage (calculated without giving effect to the Commitment Increase) of the Initial Advances and (z) such Lender's Percentage (calculated after giving effect to the Commitment Increase) of the amount of the Subsequent Advances, (E) the Lenders shall be deemed to hold the Subsequent Advances ratably in accordance with their respective Commitment (calculated after giving effect to the Commitment Increase), (F) the Borrower shall pay all accrued but unpaid interest on the Initial Advances to the Lenders entitled thereto, and (G) Schedule I shall automatically be amended to reflect the Commitments of all Lenders after giving effect to the Commitment Increase. The conversion of the Initial Advances pursuant to clause (A) above shall be subject to indemnification by the Borrower pursuant to the provisions of Section 8.4(d) if the date of any Commitment Increase occurs other than on the last day of the Interest Period relating thereto.

(iv) Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment Increase and the making of any Advances on such date pursuant to this Section 2.6(d), all calculations and payments of the Facility Fee and the LC Fee and of interest on the Advances shall take into account the actual Commitment of each Lender and such Lender's Percentage of the Outstanding Credits during the relevant period of time.

Section 2.7 Repayment of Advances.

(a) Except to the extent due or paid sooner pursuant to the provisions of this Agreement, the Borrower shall repay to the Lenders the aggregate outstanding principal amount of each Revolving Advance on the Termination Date.

(b) Except to the extent due or paid sooner pursuant to the provisions of this Agreement, the Borrower shall repay to the Swingline Lender the aggregate outstanding principal amount of each Swingline Advance on the earlier to occur of (i) fourteen days after the date of Borrowing of each such Swingline Advance, and (ii) the Swingline Termination Date.

Section 2.8 Interest on Advances. The Borrower shall pay interest on the unpaid principal amount of each Advance owing to each Lender from the date of such Advance until such principal amount shall be paid in full, at the Applicable Rate for such Advance (except as otherwise provided in this Section 2.8), payable as follows:

(a) If such Advance is a Base Rate Advance, interest thereon shall be payable quarterly in arrears on the last day of each March, June, September and December, on the date of any Conversion of such Base Rate Advance and on the date such Base Rate Advance shall become due and payable or shall otherwise be paid in full; provided that at any time an Event of Default shall have occurred and be continuing, each Base Rate Advance shall bear interest payable on demand, at a rate per annum equal at all times to the Default Rate.

(b) If such Advance is a Eurodollar Rate Advance, interest thereon shall be payable on the last day of such Interest Period and, if the Interest Period for such Advance has a duration of more than three months, on that day of each third month during such Interest Period that corresponds to the first day of such Interest Period (or, if any such month does not have a corresponding day, then on the last day of such month); provided that at any time an Event of Default shall have occurred and be continuing, each Eurodollar Rate Advance shall bear interest payable on demand, at a rate per annum equal at all times to the Default Rate.

(c) If such Advance is a LIBOR Market Index Rate Advance, interest thereon shall be payable in arrears on the last day of each March, June, September and December, and on the date such LIBOR Market Index Rate Advance shall become due and payable or shall otherwise be paid in full; provided that at any time an Event of Default shall have occurred and be continuing, each LIBOR Market Index Rate Advance shall bear interest payable on demand, at a rate per annum equal at all times to the Default Rate.

(d) In respect of any Advance, interest thereon shall be payable at the Applicable Rate at maturity (whether pursuant to acceleration or otherwise) and, after maturity, on demand.

(e) Nothing contained in this Agreement or in any other Loan Document shall be deemed to establish or require the payment of interest to any Lender at a rate in excess of the maximum rate permitted by applicable law. If the amount of interest payable for the account of any Lender on any interest payment date would exceed the maximum amount permitted by applicable law to be charged by such Lender, the amount of interest payable for its account on such interest payment date shall be automatically reduced to such maximum permissible amount. In the event of any such reduction affecting any Lender, if from time to time thereafter the amount of interest payable for the account of such Lender on any interest payment date would be less than the maximum amount permitted by applicable law to be charged by such Lender, then the amount of interest payable for its account on such subsequent interest payment date shall be automatically increased to such maximum permissible amount, provided that at no time shall the aggregate amount by which interest paid for the account of any Lender has been increased pursuant to this sentence exceed the aggregate amount by which interest paid for its account has theretofore been reduced pursuant to the previous sentence.

32


Section 2.9 Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to Agent for the account of each Lender any costs actually incurred by such Lender with respect to Eurodollar Rate Advances that are attributable to such Lender's compliance with regulations of the Board of Governors of the Federal Reserve System requiring the maintenance of reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities. Such costs shall be paid to the Agent for the account of such Lender in the form of additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Lender, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest shall be determined by such Lender and notified to the Borrower through the Agent. A certificate as to the amount of such additional interest, submitted to the Borrower and the Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error, provided that the determination thereof shall have been made by such Lender in good faith.

Section 2.10 Interest Rate Determination.

(a) The Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Agent for purposes of Section 2.8(a), Section 2.8(b) or Section 2.8(c).

(b) If, on or prior to the first day of any Interest Period, (y) the Agent shall have determined that adequate and reasonable means do not exist for ascertaining the applicable Eurodollar Rate for such Interest Period (z) the Agent shall have received written notice from the Majority Lenders of their determination that the rate of interest referred to in the definition of "Eurodollar Rate" is to be determined will not adequately and fairly reflect the cost to such Lenders of making or maintaining Eurodollar Rate Advances during such Interest Period, the Agent will forthwith so notify the Borrower and the Lenders. Upon such notice, (i) (A) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefore, Convert into a Base Rate Advance, (ii) the obligation of the Lenders to make, to Convert Advances into, or to continue, Eurodollar Rate Advances shall be suspended (including pursuant to the Borrowing to which such Interest Period applies), and (iii) any Notice of Borrowing or Notice of Conversion given at any time thereafter with respect to Eurodollar Rate Advances shall be deemed to be a request for Base Rate Advances, in each case until the Agent or the Majority Lenders, as the case may be, shall have determined that the circumstances giving rise to such suspension no longer exist (and the Majority Lenders, if making such determination, shall have so notified the Agent), and the Agent shall have so notified the Borrower and the Lenders.

(c) If the Borrower shall fail to (i) select the duration of any Interest Period for any Eurodollar Rate Advance in accordance with the provisions contained in the definition of "Interest Period" in Section 1.1 or (ii) provide a Notice of Conversion with respect to any Eurodollar Rate Advance on or prior to 12:00 noon on the third Business Day prior to the last day of the Interest Period applicable thereto, the Agent will forthwith so notify the Borrower and the Lenders and such Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance.

33


(d) On the date on which the aggregate unpaid principal amount of Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than the product of (i) $1,000,000 and (ii) the number of Lenders on such date, such Advances shall, if they are Advances of a Type other than Base Rate Advances, automatically Convert into Base Rate Advances, and on and after such date the right of the Borrower to Convert such Advances into Advances of a Type other than Base Rate Advances shall terminate; provided, however, that if and so long as each such Advance shall be of the same Type and have the same Interest Period as Advances comprising another Borrowing or other Borrowings, and the aggregate unpaid principal amount of all such Advances shall equal or exceed the product of (i) $1,000,000 and (ii) the number of Lenders on such date, the Borrower shall have the right to continue all such Advances as, or to Convert all such Advances into, Advances of such Type having such Interest Period.

(e) Upon the occurrence and during the continuance of any Event of Default, each outstanding Eurodollar Rate Advance shall automatically Convert into a Base Rate Advance at the end of the Interest Period then in effect for such Eurodollar Rate Advance.

Section 2.11 Voluntary Conversion of Advances. Subject to the conditions set forth below, the Borrower may, on any Business Day, by delivering a notice of Conversion (a "Notice of Conversion") to the Agent not later than 12:00 noon (i) on the third Business Day prior to the date of the proposed Conversion, in the case of a Conversion to or in respect of Eurodollar Rate Advances and (ii) on the date of the proposed Conversion, in the case of a Conversion to or in respect of Base Rate Advances, and subject to the provisions of Section 2.10 and Section 2.15, Convert all Advances of one Type comprising the same Borrowing into Advances of another Type; provided, however, that, (x) any such Conversion shall involve an aggregate principal amount of not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in the case of any Conversion of any Eurodollar Rate Advances into Base Rate Advances on a day other than the last day of an Interest Period for such Eurodollar Rate Advances, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.4(d). Each such Notice of Conversion shall be in substantially the form of Exhibit 2.11 and shall, within the restrictions specified above, specify (A) the date of such Conversion, (B) the Advances to be Converted, (C) if such Conversion is into Eurodollar Rate Advances, the duration of the Interest Period for each such Advance, and (D) the aggregate amount of Advances proposed to be Converted. Notwithstanding the foregoing, the Borrower may not Convert Base Rate Advances into Eurodollar Rate Advances and may not select a new Interest Period for Eurodollar Rate Advances at any time an Unmatured Default or Event of Default has occurred and is continuing.

Section 2.12 Optional Prepayments of Advances. The Borrower may, upon at least three Business Days' notice to the Agent stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given, the Borrower shall prepay for the ratable account of the Lenders the outstanding principal amounts of the Advances comprising part of the same Borrowing in whole or ratably in part, without premium or penalty, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that

34


each partial prepayment shall be in an aggregate principal amount not less than $5,000,000 (or, if lower, the entire principal amount outstanding hereunder on the date of such prepayment) or an integral multiple of $1,000,000 in excess thereof. In the case of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.4(d). Except as provided in this Section 2.12, the Borrower shall have no right to prepay any principal amount of any Advances.

Section 2.13 Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any Eurodollar Reserve Percentage) or any LC Issuing Bank;

(ii) subject any Recipient to any Taxes on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii) impose on any Lender or any LC Issuing Bank or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein;

and, to the extent that a Lender, a LC Issuing Bank or other Recipient reasonably determines that the direct result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, Converting to, continuing or maintaining any Advance or of maintaining its obligation to make any such Advance, or to increase the cost to such Lender, such LC Issuing Bank or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, Swingline Lender, LC Issuing Bank or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, Swingline Lender, LC Issuing Bank or other Recipient, the Borrower will pay to such Lender, Swingline Lender, LC Issuing Bank or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, Swingline Lender, LC Issuing Bank or other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

(b) If any Lender, the Swingline Lender or LC Issuing Bank determines that any Change in Law affects or would affect the amount of capital or liquidity required or expected to be maintained by such Lender, Swingline Lender or LC Issuing Bank or any corporation controlling such Lender, Swingline Lender or LC Issuing Bank and that the amount of such capital or liquidity is increased as a direct result of the existence of this Agreement, such Lender's Commitment or Advances made by such Lender or participations in Letters of Credit or Swingline Advances hereunder held by such Lender or the Letters of Credit issued by any LC Issuing Bank, to a level below that which such Lender, Swingline Lender or LC Issuing Bank or any corporation controlling such Lender, Swingline Lender or LC Issuing Bank could have

35


achieved but for such Change in Law (taking into consideration such Lender's, Swingline Lender's or LC Issuing Bank's policies and the policies of such Lender's or LC Issuing Bank's holding company with respect to capital adequacy), then, upon demand by such Lender, Swingline Lender or LC Issuing Bank (with a copy of such demand to the Agent), the Borrower shall immediately pay to the Agent for the account of such Lender, Swingline Lender or LC Issuing Bank, from time to time as specified by such Lender, Swingline Lender or LC Issuing Bank, additional amounts sufficient to compensate such Lender, Swingline Lender or LC Issuing Bank or such corporation in the light of such circumstances, to the extent that such Lender, Swingline Lender or LC Issuing Bank reasonably determines such increase in capital or liquidity to be allocable to the existence of such Lender's Commitment, Swingline Lender's obligations hereunder or LC Issuing Bank's obligations hereunder.

(c) A certificate of a Lender, Swingline Lender or LC Issuing Bank setting forth the amount or amounts necessary to compensate such Lender, Swingline Lender or Issuing Bank or any corporation controlling such Lender, Swingline Lender or LC Issuing Bank, as the case may be, as specified in paragraph (a) or (b) of this Section 2.13 and delivered to the Borrower, shall certify in reasonable detail as to the increased cost for which it is seeking compensation hereunder and shall be conclusive absent manifest error; provided that the determination thereof shall have been made by such Lender, Swingline Lender or LC Issuing Bank in good faith. The Borrower shall pay such Lender, Swingline Lender or LC Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Failure or delay on the part of any Lender, Swingline Lender or LC Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender's, Swingline Lender's or LC Issuing Bank's right to demand such compensation; provided, no Lender, Swingline Lender or LC Issuing Bank shall be entitled to demand compensation or be compensated thereunder to the extent that such compensation relates to any period of time more than ninety days prior to the date upon which such Lender, Swingline Lender or LC Issuing Bank first notified the Borrower of the occurrence of the event entitling such Lender, Swingline Lender or LC Issuing Bank 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).

Section 2.14 Illegality. Notwithstanding any other provision of this Agreement to the contrary, if at any time after the date hereof and from time to time, any Lender (the "Affected Lender") shall notify the Agent and the Borrower that any Change in Law makes it unlawful or any Governmental Authority asserts that it is unlawful, for the Affected Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, following such notice from the Affected Lender, (i) all Eurodollar Rate Advances of the Affected Lender shall, on the expiration date of the respective Interest Period applicable thereto (or, to the extent any such Eurodollar Rate Advance may not lawfully be maintained as a Eurodollar Rate Advance until such expiration date, upon such notice) automatically be Converted into Base Rate Advances (each such Advance, as so Converted, being an "Affected Lender Advance"), (ii) the obligation of the Affected Lender to make, maintain, or Convert Advances into Eurodollar Rate Advances shall thereupon be suspended, and (iii) any Notice of Borrowing or Notice of Conversion given at any time thereafter with respect to Eurodollar Rate Advances shall, as to the Affected Lender, be

36


deemed a request for Base Rate Advances, in each case until the Affected Lender shall have determined that the circumstances causing such suspension no longer exist and shall have so notified the Agent, or the Affected Lender has been replaced pursuant to Section 2.20(a) and, in either case the Agent shall have notified the Borrower and the other Lenders. For purposes of any prepayment under this Agreement, each Affected Lender Advance shall be deemed to continue to be part of the same Borrowing as the Eurodollar Rate Advances to which it corresponded at the time of the Conversion of such Affected Lender Advance pursuant to this Section 2.14.

Section 2.15 Payments and Computations.

(a) The Borrower shall make each payment hereunder not later than 1:00 p.m. on the day when due in Dollars to the Agent at its address referred to in Section 8.2 in same day funds. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or fees ratably (other than amounts payable pursuant to Section 2.17, Section 2.19 or Section 8.4(d)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of a Lender Assignment and recording of the information contained therein in the Register pursuant to Section 8.7(b), from and after the effective date specified in such Lender Assignment, the Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Lender Assignment shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder held by such Lender, to charge from time to time against any or all of the Borrower's accounts with such Lender any amount so due.

(c) All computations of interest based on clause (i) of the definition of "Alternate Base Rate" and of the Facility Fees shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate, LIBOR Market Index Rate and the LC Fee and the Federal Funds Rate shall be made by the Agent, and all computations of interest pursuant to Section 2.10 shall be made by a Lender, on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Agent (or, in the case of Section 2.10, by a Lender) of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error, provided that such determination shall have been made by the Agent or such Lender, as the case may be, in good faith.

(d) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the immediately preceding Business Day.

37


(e) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at the Federal Funds Rate.

(f) The Borrower shall be entitled to rely upon payment instructions and other information relating the amounts owed by it hereunder provided by the Agent and believed by the Borrower to be genuine and to have been signed, sent or otherwise authenticated by the proper person acting for the Agent and shall have no liability solely with respect to such reliance, provided that no such reliance by the Borrower shall in any way relieve or otherwise impair any obligation of the Borrower hereunder, including its obligations under Section 8.4.

Section 2.16 Noteless Agreement; Evidence of Indebtedness.

(a) 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 Advance 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.

(b) The Agent shall also maintain accounts in which it will record (i) the amount of each Advance made hereunder, the Class and Type thereof and the Interest Period (if any) with respect thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, and (iii) the amount of any sum received by the Agent hereunder from the Borrower and each Lender's share thereof.

(c) The entries maintained in the accounts maintained pursuant to Section 2.16(a) and Section 2.16(b) shall be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of the 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 such obligations in accordance with their terms.

(d) The Advances of each Class made by each Lender shall, if requested by the applicable Lender (which request shall be made to the Agent), be evidenced (i) in the case of Revolving Advances, by a Revolving Note, and (ii) in the case of the Swingline Advances, by a Swingline Note, in each case appropriately completed and executed by the Borrower and payable to the order of such Lender. Each Note shall be entitled to all of the benefits of this Agreement and the other Loan Documents and shall be subject to the provisions hereof and thereof.

38


Section 2.17 Taxes.

(a) Any and all payments by the Borrower hereunder and under the other Loan Documents shall be made, in accordance with Section 2.15, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Recipient, (i) any U.S. federal withholding taxes imposed under FATCA, including, without limitation, any tax that would not have been imposed but for a failure by a Person (or any financial institution through which any payment is made to such Person) (including a participant or any other recipient of any payment hereunder) to comply with the procedures, certifications, information, reporting, disclosure and other related requirements of FATCA, (ii) taxes imposed on its overall net income and franchise taxes imposed on it by any jurisdiction, unless such Lender, the LC Issuing Bank or the Agent (as the case may be) would not have had such taxes imposed on it by such jurisdiction but for such Lender's, the LC Issuing Bank's or the Agent's (as the case may be) having entered into this Agreement, having consummated the transactions contemplated hereby or having received payments by the Borrower hereunder or under the other Loan Documents, and (iii) any similar taxes imposed as a result of a present or former connection between such Recipient and the jurisdiction imposing such tax (other than connections arising from such Recipient having executed, delivered, become a party to, performed its obligations under, received payments under, received or perfected a security interest under, engaged in any other transaction pursuant to or enforced any Loan Document, or sold or assigned an interest in any Advance or Loan Document (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any other Loan Document to any Lender, the LC Issuing Bank or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.17) such Lender, the LC Issuing Bank or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any other Loan Document or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or any other Loan Document (hereinafter referred to as "Other Taxes").

(c) The Borrower will indemnify each Lender, the LC Issuing Bank and the Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.17) paid by such Lender, the LC Issuing Bank or the Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within thirty days from the date such Lender, the LC Issuing Bank or the Agent (as the case may be) makes written demand therefor. Nothing herein shall preclude the right of the Borrower to contest any such Taxes or Other Taxes so paid, and the Lenders in question, the LC Issuing Bank or the Agent (as the case may be) will, following notice from, and at the expense of, the Borrower, reasonably cooperate with the Borrower to preserve the Borrower's rights to contest such Taxes or Other Taxes.

39


(d) Within thirty days after the date of any payment of Taxes, the Borrower will furnish to the Agent, at its address referred to in Section 8.2, the original or a certified copy of a receipt evidencing payment thereof.

(e) The LC Issuing Bank and each Lender agrees that, on or prior to the date upon which it shall become a party hereto, and upon the reasonable request from time to time of the Borrower or the Agent, the LC Issuing Bank or such Lender will deliver to the Borrower and the Agent either (i) a statement that it is organized under the laws of a jurisdiction within the United States or (ii) duly completed copies of such form or forms as may from time to time be prescribed by the United States Internal Revenue Service indicating that the LC Issuing Bank or such Lender is entitled to receive payments without deduction or withholding of any United States federal income taxes, as permitted by the Internal Revenue Code of 1986, as amended from time to time. The LC Issuing Bank and each Lender that delivers to the Borrower and the Agent the form or forms referred to in the preceding sentence further undertakes to deliver to the Borrower and the Agent further copies of such form or forms, or successor applicable form or forms, as the case may be, as and when any previous form filed by it hereunder shall expire or shall become incomplete or inaccurate in any respect. The LC Issuing Bank and each Lender represents and warrants that each such form supplied by it to the Agent and the Borrower pursuant to this Section 2.17(e), and not superseded by another form supplied by it, is or will be, as the case may be, complete and accurate.

(f) Any Lender claiming any additional amounts payable pursuant to this Section 2.17 shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

(g) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in this Section 2.17 shall survive the payment in full of principal and interest hereunder.

Section 2.18 Sharing of Payments, Etc. All payments from or on behalf of the Borrower on account of any obligations shall be apportioned ratably among the Lenders based upon their respective share, if any, of the obligations with respect to which such payment was received. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set off, or otherwise) on account of the Advances made by it (other than pursuant to Section 2.13, Section 2.17, Section 2.19 or Section 8.4(d)) or on account of the Borrower's reimbursement obligations in respect of LC Outstandings in excess of its ratable share of payments obtained by all the Lenders on account of the Advances or on account of such reimbursement obligations, such Lender shall forthwith purchase (for cash at face value) from the other Lenders such participations in the Advances made by them and such reimbursement obligations as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that (a) if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery, together with an amount equal to such Lender's ratable share (according

40


to the proportion of (i) the amount of such Lender's required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered and (b) the provisions of this paragraph shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Advances or participations in reimbursement obligations or Swingline Advances to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this paragraph shall apply). The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.18 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

Section 2.19 Extension of Termination Date.

(a) So long as no Unmatured Default or Event of Default has occurred and is continuing and subject to the conditions set forth in Section 2.19(c), the Borrower may, no earlier than sixty days and no later than thirty days prior to each anniversary of the Amendment Effective Date (such anniversary, an "Extension Date"), but on no more than two occasions, request through written notice to the Agent (the "Extension Notice"), that the Lenders extend the then existing Termination Date for an additional one-year period. Each Lender, acting in its sole discretion, shall, by notice to the Agent no later than the applicable Extension Date (except in the year in which the then existing Termination Date shall occur, in which case such written notice shall be delivered by the Lenders no later than fifteen days prior to the then existing Termination Date) (such date, the "Consent Date"), advise the Agent in writing of its desire to extend (any such Lender, a "Consenting Lender") or not to so extend (any such Lender, a "Non-Consenting Lender") such date. Any Lender that does not advise the Agent by the Consent Date shall be deemed to be a Non-Consenting Lender. No Lender shall be under any obligation or commitment to extend the then existing Termination Date. The election of any Lender to agree to such extension shall not obligate any other Lender to agree to such extension.

(b) If the Majority Lenders (determined as of the Consent Date) shall have agreed to such extension, then the then existing Termination Date applicable to the Consenting Lenders shall be extended to the date that is one year after the then existing Termination Date. All Advances of each Non-Consenting Lender shall be subject to the then existing Termination Date, without giving effect to such extension (such date, the "Prior Termination Date"). In the event of an extension of the then existing Termination Date pursuant to this Section 2.19, the Borrower shall have the right, at its own expense, to solicit commitments from existing Lenders and/or Eligible Assignees reasonably acceptable to the Agent and the LC Issuing Bank to replace the Commitment of any Non-Consenting Lenders for the remaining duration of this Agreement. Any Eligible Assignee (if not already a Lender hereunder) shall become a party to this Agreement as a Lender pursuant to a joinder agreement in form and substance reasonably satisfactory to the Agent and the Borrower. The Commitment of each Non-Consenting Lender shall terminate on the Prior Termination Date, all Advances and other amounts payable hereunder to such Non-Consenting Lenders shall be subject to the Prior Termination Date and, to

the extent such Non-Consenting Lender's Commitment is not replaced as provided above, the Aggregate Commitment hereunder shall be reduced by the amount of the Commitment of each such Non-Consenting Lender so terminated on the Prior Termination Date. Notwithstanding anything to the contrary in this Section 2.19, the Termination Date shall not be extended unless the aggregate Commitments of the Consenting Lenders and any Eligible Assignees joining this Agreement pursuant to this Section 2.19(b) are greater than or equal to the Outstanding Credits as of each Prior Termination Date.

(c) An extension of the Termination Date pursuant to this Section 2.19 shall only become effective upon the receipt by the Agent of a certificate (the statements contained in which shall be true) of a duly authorized officer of the Borrower stating that both before and after giving effect to such extension of the Termination Date (i) no Unmatured Default or Event of Default has occurred and is continuing and (ii) all representations and warranties contained in Section 4.1 are true and correct in all material respects on and as of the date such extension is made, except for such representations or warranties which by their terms are made as of a specified date, which shall be true and correct as of such specified date.

(d) Effective on and after the Prior Termination Date, (i) each of the Non-Consenting Lenders shall be automatically released from their respective participations and reimbursement obligations under Section 2.4 with respect to any LC Outstandings and (ii) the participations and reimbursement obligations of each Lender (other than the Non-Consenting Lenders) shall be automatically adjusted to equal such Lender's Percentage of such LC Outstandings.

Section 2.20 Replacement of Lenders.

(a) The Borrower may, at any time at its sole expense and effort, require any Lender that (x) requests compensation under Section 2.9, Section 2.13 or Section 2.14, or requires the Borrower to pay any Taxes or additional amounts under Section 2.17, (y) does not approve a consent, waiver or amendment to any Loan Document requested by the Borrower or the Agent and that requires the approval of all Lenders under Section 8.1 which is otherwise approved by the Majority Lenders, or (z) is a Defaulting Lender, upon notice to such Lender and the Agent, to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 8.7), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(i) no Unmatured Default or Event of Default shall have occurred and be continuing at such time;

(ii) the Agent shall have received the assignment fee specified in Section 8.7(a);

(iii) such Lender shall have received payment of an amount equal to the outstanding principal of its Advances and any funded participations in Letters of Credit not refinanced through the Borrowing of Revolving Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 8.4(d)) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

42


(iv) such assignee, if it is not an existing Lender and/or Eligible Assignee, shall be reasonably satisfactory to the Agent;

(v) such assignment does not conflict with any applicable Requirement of Law; and

(vi) in the case of assignment from a Lender as a result of (y) above, the applicable assignee shall have consented to the applicable amendment, waiver or consent.

A Lender shall not be required to make any assignment or delegation if, prior thereto, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

(b) At any time a Lender is a Designated Lender, the Borrower may terminate in full the Commitment of such Designated Lender by giving notice to such Designated Lender and the Agent, effective as of the date such notice has been received by both such Designated Lender and the Agent; provided that (i) at the time of such termination, (x) no Event of Default or Unmatured Default exists (or the Majority Lenders consent to such termination) and (y) no Advances are outstanding; (ii) concurrently with such termination, the Aggregate Commitments shall be reduced by the Commitment of such Designated Lender (it being understood that the Borrower may not terminate the Commitment of a Designated Lender if, after giving effect to such termination, the Outstanding Credits would exceed the Aggregate Commitment); and (iii) concurrently with any subsequent payment of interest or fees to the Lenders with respect to any period before the termination of the Commitment of such Designated Lender, the Borrower shall pay to such Designated Lender its ratable share (based upon the percentage of the Aggregate Commitments represented by such Defaulting Lender's Commitment before giving effect to such termination) of such interest or fees, as applicable. The termination of the Commitment of a Defaulting Lender pursuant to this Section 2.20(b) shall not deemed to be a waiver of any right that the Borrower, the Agent, the LC Issuing Bank or any other Lender may have against such Defaulting Lender.

Section 2.21 Defaulting Lenders.

(a) Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender (including as a result of termination of its Commitments pursuant to Section 2.20(b)), to the extent permitted by applicable law:

(i) Such Defaulting Lender's right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Majority Lenders and in Section 8.1.

(ii) Any payment of principal, interest, fees or other amounts received by the Agent hereunder for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to ARTICLE VI or otherwise) or received by the Agent from a Defaulting Lender pursuant to Section 6.1 shall be applied at such time or times as may be determined by the Agent as follows:

(A) first, to the payment of any amounts owing by such Defaulting Lender to the Agent hereunder;

43


(B) second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the LC Issuing Bank or the Swingline Lender hereunder;

(C) third, if so determined by the Agent or requested by the LC Issuing Bank or the Swingline Lender, to be held as Cash Collateral for future funding obligations of such Defaulting Lender in respect of any participation in any Letter of Credit or Swingline Loan;

(D) fourth, as the Borrower may request (so long as no Unmatured Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Agent;

(E) fifth, if so determined by the Agent and the Borrower, to be held in a non-interest bearing deposit account and released in order to satisfy obligations of such Defaulting Lender to fund Advances under this Agreement;

(F) sixth, to the payment of any amounts owing to the Lenders, the LC Issuing Bank or the Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the LC Issuing Bank or the Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement;

(G) seventh, so long as no Unmatured Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; and

(H) eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction;

provided that if (x) such payment is a payment of the principal amount of any Advances or any LC Outstandings in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Advances were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 3.1 were satisfied or waived, such payment shall be applied solely to pay the Advances of, and obligations in respect of Letters of Credit owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Advances of, or obligations in respect of Letters of Credit owed to, such Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.21(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

44


(iii) Any Defaulting Lender shall be entitled to receive any Facility Fee for any period during which such Lender is a Defaulting Lender only to the extent allocable to the sum of (1) the outstanding amount of the Revolving Advances funded by it and (2) its LC Outstandings and Swingline Exposure for which it has provided Cash Collateral pursuant to Section 2.21(c) (and the Borrower shall (A) be required to pay the LC Issuing Bank and the Swingline Lender the amount of such fee allocable to its Fronting Exposure arising from such Defaulting Lender and (B) not be required to pay the remaining amount of such fee that otherwise would have been required to have been paid to such Defaulting Lender).

(iv) All or any part of such Defaulting Lender's LC Outstandings and Swingline Exposure shall automatically (effective on the day such Lender becomes a Defaulting Lender) be reallocated among the non-Defaulting Lenders in accordance with their respective Credit Exposures (calculated without regard to such Defaulting Lender's Commitment) but only to the extent that (x) no Default shall have occurred and be continuing (and, unless the Borrower shall have otherwise notified the Agent at the time, the Borrower shall be deemed to have represented and warranted that such condition is satisfied at such time) and (y) such reallocation does not cause the Credit Exposure of any non-Defaulting Lender to exceed such non-Defaulting Lender's Commitment.

(v) If the reallocation described in Section 2.21(a)(iv) cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, within two Business Days following notice by the Agent, Cash Collateralize such Defaulting Lender's LC Outstandings and its Swingline Exposure (after giving effect to any partial reallocation pursuant to Section 2.21(a)(iv)) in accordance with the procedures set forth in Section 2.21(c).

(b) If the Borrower, the Agent, the LC Issuing Bank and the Swingline Lender agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable, purchase that portion of outstanding Advances of the other Lenders or take such other actions as the Agent may determine to be necessary to cause the Revolving Advances and funded and unfunded participations in Letters of Credit and Swingline Advances to be held on a pro rata basis by the Lenders in accordance with their respective Credit Exposures (without giving effect to Section 2.21(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while such Lender was a Defaulting Lender; provided further that, except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender's having been a Defaulting Lender.

45


(c) At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of the Agent, the LC Issuing Bank or the Swingline Lender, the Borrower shall Cash Collateralize all Fronting Exposure with respect to such Defaulting Lender (determined after giving effect to Section 2.21(a)(iv) and any Cash Collateral provided by such Defaulting Lender).

(i) The Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Agent, the LC Issuing Bank and the Lenders (including the Swingline Lender) and agrees to maintain, a first priority security interest in all such Cash Collateral as security for the Defaulting Lenders' obligation to fund participations in respect of the obligations to which such Cash Collateral may be applied pursuant to Section 2.21(c)(ii). If at any time the Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Agent and the LC Issuing Banks as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure, the Borrower will, promptly upon demand by the Agent, pay or provide to the Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender).

(ii) Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 2.21 in respect of Letters of Credit or Swingline Advances shall be applied to the satisfaction of the Defaulting Lender's obligation to fund participations in respect of the applicable Letters of Credit and Swingline Advances (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii) Cash Collateral (or the appropriate portion thereof) provided to reduce any Fronting Exposure or other obligations shall no longer be required to be held as Cash Collateral pursuant to this Section 2.21 following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender), or (ii) the determination by the Agent that there exists excess Cash Collateral; provided however that, (x) Cash Collateral furnished by the Borrower shall not be released during the continuance of a Default (and following application as provided in this Section 2.21 may otherwise be applied in accordance with Section 2.18) and (y) the Person providing Cash Collateral and the LC Issuing Bank or Swingline Lender, as applicable, may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations.

ARTICLE VII

THE AGENT

Section 7.1 Authorization and Action. Each of the Lenders (for purposes of this ARTICLE VII, references to the Lenders shall also mean the LC Issuing Bank and the Swingline Lender) hereby appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Agent by the terms hereof, together with such powers as are reasonably incidental thereto. Except as set forth in Section 7.7, the provisions of this ARTICLE VII are solely for the benefit of the Agent and the Lenders, the Borrower shall have no rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the term "agent" (or any other similar term) herein or in any other Loan Document with reference to the Agent is not intended to connote any fiduciary or other implied (or express) obligations under agency doctrine of any applicable law. Instead, such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

Section 7.2 Exculpatory Provisions.

(a) The Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Agent:

(i) shall not be subject to any fiduciary or other implied duties, regardless of whether a Unmatured Default or Event of Default has occurred and is continuing;

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Agent is required to exercise as directed in writing by the Majority Lenders; provided that the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Loan Document or applicable law, including, for the avoidance of doubt, any action that may be in violation of the automatic stay under the Federal Bankruptcy Code or under any other applicable bankruptcy, insolvency or similar law now or hereafter in effect or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any such law; and

62


(iii) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Agent or any of its Affiliates in any capacity.

(b) The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Majority Lenders (or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 8.1 and Section 6.1), or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Agent shall be deemed not to have knowledge of any Unmatured Default or Default unless and until notice describing such Unmatured Default or Event of Default is given to the Agent in writing by the Borrower or a Lender.

Section 7.3 Reliance by Agent. The Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of an Advance or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or the LC Issuing Bank, the Agent may presume that such condition is satisfactory to such Lender or the LC Issuing Bank unless the Agent shall have received notice to the contrary from such Lender or the LC Issuing Bank prior to the making of such Advance or the issuance, extension, renewal or increase of such Letter of Credit. The Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 7.4 Wells Fargo and Affiliates. With respect to its Commitment and the Advances made by it, Wells Fargo shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Agent or the LC Issuing Bank; and the term "Bank" or "Banks" and "Lender" or "Lenders" shall, unless otherwise expressly indicated, include Wells Fargo in its individual capacity. Wells Fargo and its Affiliates may accept deposits from, lend money to, act as the financial advisor or the trustee under indentures of, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof and any Person who may do business with or own securities of the Borrower or any Subsidiary or other Affiliate thereof, all as if Wells Fargo were not the Agent and without any duty to account therefor to the Lenders.

63


Section 7.5 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on the financial statements referred to in Section 4.1(f) and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

Section 7.6 Indemnification. The Lenders agree to indemnify the Agent and any Related Party of the Agent participating in the transaction (to the extent not reimbursed by the Borrower), ratably according to (i) on or before the Termination Date, the respective Percentages of the Lenders, or (ii) after the Termination Date, the respective outstanding principal amounts of the Advances, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or any action taken or omitted by the Agent under this Agreement; provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Agent's gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its ratable share of any out of pocket expenses (including counsel fees) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower.

Section 7.7 Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower. Upon any such resignation, the Majority Lenders shall have the right to appoint a successor Agent, which shall be a Lender or shall be another commercial bank or trust company (and reasonably acceptable to the Borrower so long as no Unmatured Default or Event of Default exists) organized under the laws of the United States or of any State thereof. If no successor Agent shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within thirty days after the retiring Agent's giving of notice of resignation (the "Resignation Effective Date"), then the retiring Agent shall, on behalf of the Lenders, appoint a successor Agent, which shall be a Lender or shall be another commercial bank or trust company organized under the laws of the United States of any State thereof reasonably acceptable to the Borrower. Regardless of whether a successor has been appointed or has accepted such appointment, such resignation of the retiring Agent shall become effective in accordance with such notice on the Resignation Effective Date. Notwithstanding the foregoing, if either the Majority Lenders or the Borrower have not accepted the appointment of a successor Agent or no successor Agent has accepted appointment to act as the Agent hereunder as of the Resignation Effective Date, then the Majority Lenders shall be deemed to have succeeded to and become vested with all the rights, powers, privileges and duties of the retiring Agent as of the Resignation Effective Date. With effect from the Resignation Effective Date, (i) the retiring Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents and (ii) except for any indemnity payments

64


owed to the retiring Agent, all payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each Lender directly, until such time, if any, as the Majority Lenders appoint a successor administrative agent as provided for in this Section 7.7. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Agent's resignation or removal hereunder as Agent, the provisions of this Article VII and Section 8.4 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

Section 7.8 Delegation of Duties. The Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Agent; provided, however, that the Agent shall remain responsible for the performance of its duties under this Agreement and the Loan Documents to the extent required under this Article VII. The Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as the Agent.

Section 7.9 No Other Duties, Etc.

Section 7.10 Agent May File Proofs of Claim. In case of the pendency of any proceeding under the Federal Bankruptcy Code or under any other applicable bankruptcy, insolvency or similar law now or hereafter in effect or any other judicial proceeding relative to the Borrower, the Agent (irrespective of whether the principal of any Advance or reimbursement obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise (i) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Advances, reimbursement obligations and all other obligations that are owing and unpaid and to file such other documents as may be necessary advisable in order to have the claims of the Lenders and the Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Agent and their respective agents, sub-agents and counsel and all other amounts due the Lenders and the Agent under Section 2.5 and Section 8.4) allowed in such judicial proceeding and (ii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Agent and, in the event that the Agent shall consent to the making of such payments to the Lenders, to pay to the Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Agent and its agents, sub-agents and counsel, and any other amounts due the Agent under Section 2.5 or Section 8.4.

Section 8.4 Costs, Expenses, Taxes and Indemnification.

(a) The Borrower agrees to pay on demand all costs and expenses of the Agent and the Joint Arrangers in connection with the preparation (including, without limitation, printing costs), syndication, negotiation, execution, delivery, modification and amendment of this Agreement and the other Loan Documents, and the other documents and instruments to be delivered hereunder and thereunder, including, without limitation, the reasonable fees and out of pocket expenses of counsel for the Agent and the Joint Arrangers with respect thereto and with respect to the administration of, and advising the Agent as to its rights and responsibilities under, this Agreement and the other Loan Documents. The Borrower further agrees to pay on demand all costs and expenses, if any (including, without limitation, reasonable counsel fees and expenses of the Agent, each LC Issuing Bank and each Lender), in connection with the enforcement and workout (whether through negotiations, legal proceedings or otherwise) of this Agreement and the other Loan Documents and the other documents and instruments to be delivered hereunder and thereunder, including, without limitation, reasonable counsel fees and expenses in connection with the enforcement of rights under this Section 8.4. In addition, the Borrower shall pay any and all Other Taxes payable or determined to be payable in connection with the execution and delivery of this Agreement and the other Loan Documents, and the other documents and instruments to be delivered hereunder and thereunder, and agrees to save the Agent, each LC Issuing Bank and each Lender harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such Other Taxes.

(b) The Borrower hereby agrees to indemnify and hold each Lender, the Agent (and any sub-agent thereof), the Joint Arrangers, the Swingline Lender, each LC Issuing Bank and each Related Party of any of the foregoing Persons (each, an "Indemnified Person") harmless from and against any and all claims, damages, losses, liabilities, costs or expenses (including reasonable attorney's fees and expenses, whether or not such Indemnified Person is named as a party to any proceeding or is otherwise subjected to judicial or legal process arising from any such proceeding) which any of them may incur or which may be claimed against any of them by any Person including the Borrower (except for such claims, damages, losses, liabilities, costs and expenses resulting from such Indemnified Person's gross negligence or willful misconduct):

(i) by reason of or resulting from the execution, delivery or performance of any of the Loan Documents or any transaction contemplated thereby, or the use by the Borrower of the proceeds of any Advance or the use by the Borrower or any beneficiary of any Letter of Credit of such Letter of Credit;

(ii) in connection with any documentary taxes, assessments or charges made by any Governmental Authority by reason of the execution and delivery of any of the Loan Documents;

(iii) in connection with or resulting from the utilization, storage, disposal, treatment, generation, transportation, release or ownership of any Hazardous Substance (A) at, upon, or under any property of the Borrower or any of its Affiliates or (B) by or on behalf of the Borrower or any of its Affiliates at any time and in any place; or

68


(iv) in connection with or resulting from the use by unintended recipients of any information or other materials distributed by it through the internet, SyndTrak or other similar transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

In case any action or proceeding is instituted involving any Indemnified Person for which indemnification is to be sought hereunder by such Indemnified Person, then such Indemnified Person will promptly notify the Borrower of the commencement of any action or proceeding; provided, however, that the failure so to notify the Borrower will not relieve the Borrower from any liability that the Borrower may have to such Indemnified Person pursuant hereto or from any liability that it may have to such Indemnified Person other than pursuant hereto. Notwithstanding the above, following such notification, the Borrower may elect in writing to assume the defense of such action or proceeding, and, upon such election, the Borrower will not, as long as it diligently conducts such defense, be liable for any legal costs subsequently incurred by such Indemnified Person (other than reasonable costs of investigation and providing evidence) in connection therewith, unless (i) the Borrower has failed to provide counsel reasonably satisfactory to such Indemnified Person in a timely manner, (ii) the Indemnified Person determines in good faith that joint representation would be inappropriate, including any actual or potential conflict of interest or (iii) the Indemnified Person reasonably determines that there may be legal defenses available to it which are different from, or in addition to those available to the Borrower. If the Borrower assumes the defense of any such action or proceeding, (a) it will be conclusively established for purposes of this Agreement that the claims made with respect thereto are subject to indemnification hereunder; (b) no compromise or settlement of such claims may be effected by the Borrower without the Indemnified Person's consent and (c) the Indemnified Person will have no liability with respect to any compromise or settlement of such claims effected without its consent. Notwithstanding the foregoing, if any Indemnified Person determines in good faith that there is a reasonable probability that any action or proceeding may adversely affect it or its affiliates other than as a result of monetary damages for which it would be entitled to indemnification hereunder, such Indemnified Person may, by notice to the Borrower, assume the exclusive right to defend, compromise, or settle such action or proceeding, but the Borrower will not be bound (but will retain its indemnification obligations hereunder) by any determination of an action or proceeding so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld). In connection with any one action or proceeding, the Borrower will not be responsible for the fees and expenses of more than one separate law firm (in addition to local counsel) for all Indemnified Persons.

(c) To the extent that the Borrower for any reason fails to indefeasibly pay any amount required under paragraph (a) or (b) of this Section 8.4 to be paid by it to the Agent (or any sub-agent thereof), any LC Issuing Bank, any Swingline Lender or any Related Party of any of the foregoing, each Lender severally agrees to pay to the Agent (or any such sub-agent), such LC Issuing Bank, such Swingline Lender or such Related Party, as the case may be, such Lender's pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought based on each Lender's Credit Exposure at such time) of such unpaid amount (including any such unpaid amount in respect of a claim asserted by such Lender); provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Agent (or any such

69


sub-agent), such LC Issuing Bank or the Swingline Lender in its capacity as such, or against any Related Party of any of the foregoing acting for the Agent (or any such sub-agent), any LC Issuing Bank or the Swingline Lender in connection with such capacity. The obligations of the Lenders under this paragraph (c) are subject to the provisions of Section 2.3(b).

(d) The Borrower will compensate each Lender upon demand for all losses, expenses and liabilities (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund or maintain Eurodollar Rate Advances) that such Lender may incur or sustain (i) if for any reason (other than a default by such Lender) a Borrowing or continuation of, or Conversion into, a Eurodollar Rate Advance does not occur on a date specified therefor in a Notice of Borrowing or Notice of Conversion, (ii) if any repayment, prepayment or Conversion of any Eurodollar Rate Advance occurs on a date other than the last day of an Interest Period applicable thereto (including as a consequence of any assignment made pursuant to Section 2.20 or any acceleration of the maturity of the Advances pursuant to Section 6.1), (iii) if any prepayment of any Eurodollar Rate Advance is not made on any date specified in a notice of prepayment given by the Borrower or (iv) as a consequence of any other failure by the Borrower to make any payments with respect to any Eurodollar Rate Advance when due hereunder. Calculation of all amounts payable to a Lender under this Section 8.4(a) shall be made as though such Lender had actually funded its relevant Eurodollar Rate Advance through the purchase of a Eurodollar deposit bearing interest at the Eurodollar Rate Advance in an amount equal to the amount of such Eurodollar Rate Advance, having a maturity comparable to the relevant Interest Period; provided, however, that each Lender may fund its Eurodollar Rate Advances in any manner it sees fit and the foregoing assumption shall be utilized only for the calculation of amounts payable under this Section 8.4(a). A certificate (which shall be in reasonable detail) showing the bases for the determinations set forth in this Section 8.4(a) by any Lender as to any additional amounts payable pursuant to this Section 8.4(a) shall be submitted by such Lender to the Borrower either directly or through the Agent. Determinations set forth in any such certificate made in good faith for purposes of this Section 8.4(a) of any such losses, expenses or liabilities shall be conclusive absent manifest error.

(e) The Borrower's obligations under this Section 8.4 shall survive the repayment of all amounts owing to the Lenders hereunder and the termination of the Commitments. If and to the extent that the obligations of the Borrower under this Section 8.4 are unenforceable for any reason, the Borrower agrees to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law.

Section 8.5 Right of Set-off.

(a) Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent by the Majority Lenders specified by Section 6.1 to authorize the Agent to declare all amounts owing hereunder due and payable pursuant to the provisions of Section 6.1, each Lender, each LC Issuing Bank and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender, such LC Issuing Bank or Affiliate to or for the credit or the account of the Borrower against any

70


and all of the obligations of the Borrower now or hereafter existing under any Loan Document, irrespective of whether or not such Lender, such LC Issuing Bank or Affiliate shall have made any demand under such Loan Document and although such obligations may be unmatured or contingent or are owed to a branch, office or Affiliate of such Lender or such LC Issuing Bank different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting Lender shall exercise any such right of set-off, (x) all amounts so set off shall be paid over immediately to the Agent for further application in accordance with the provisions of Section 2.21 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Agent, the LC Issuing Banks, and the Lenders, and (y) the Defaulting Lender shall provide promptly to the Agent a statement describing in reasonable detail the obligations owing to such Defaulting Lender as to which it exercised such right of set-off. Each Lender agrees promptly to notify the Borrower after any such set-off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender under this Section 8.5 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which such Lender may have.

(b) The Borrower agrees that it shall have no right of set-off, deduction or counterclaim in respect of its obligations hereunder, and that the obligations of the Lenders hereunder are several and not joint. Nothing contained herein shall constitute a relinquishment or waiver of the Borrower's rights to any independent claim that the Borrower may have against the Agent, any LC Issuing Bank or any Lender for the Agent's, such LC Issuing Bank's or such Lender's, as the case may be, gross negligence or willful misconduct; provided that no Lender shall be liable for the conduct of the Agent, any LC Issuing Bank or any other Lender; provided, further, that the Agent shall not be liable for the conduct of any Lender or any LC Issuing Bank, and no LC Issuing Bank shall be liable for the conduct of any Lender or the Agent; provided, however that none of the Agent, any Lender or any LC Issuing Bank shall be liable to the Borrower for any amounts representing indirect, special, consequential or punitive damages (as opposed to direct or actual damages) suffered by the Borrower.

Section 8.6 Binding Effect. This Agreement shall become effective when it shall have been executed by the Borrower and the Agent and when the Agent shall have been notified in writing by each Bank that such Bank has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Agent, each LC Issuing Bank and each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders.

Section 8.7 Assignments and Participations.

(a) Assignment by Lenders. Each Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under the Loan Documents (including, without limitation, all or a portion of its Commitment, the Advances owing to it, its participations in Letters of Credit and Swingline Advances, and the Note or Notes (if any) held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all of the assigning Lender's rights and obligations under the Loan Documents, (ii) the amount of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Lender Assignment with respect to such

71


assignment) shall in no event be less than the lesser of the amount of such Lender's then remaining Commitment and $5,000,000 or any whole multiple of $1,000,000 in excess thereof (except in the case of assignments between Lenders at the time already parties hereto and between a Lender and an Affiliate of such Lender or Approved Fund), (iii) except as set forth in clause (ii) below, the Agent, each LC Issuing Bank and, so long as no Unmatured Default or Event of Default shall have occurred and be continuing, the Borrower, shall have consented to such assignment (in each case, which may not be unreasonably withheld or delayed); provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Agent within ten Business Days after having received notice thereof, and (iv) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, a Lender Assignment, together with any Note or Notes (if any) subject to such assignment and a processing and recordation fee of $3,500. Promptly following its receipt of such Lender Assignment, Note or Notes (if any) and fee, the Agent shall accept and record such Lender Assignment in the Register.

(i) Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Lender Assignment, (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Lender Assignment, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Lender Assignment, relinquish its rights and be released from its obligations under this Agreement (and, in the case of a Lender Assignment covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto, but shall continue to be entitled to the benefits of Section 2.13, Section 2.17, and Section 8.4 with respect to facts and circumstances occurring prior to the effective date of such assignment); provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender's having been a Defaulting Lender.

(ii) Notwithstanding anything to the contrary contained in this Agreement, any Lender may at any time, with notice to the Borrower, the Agent and the LC Issuing Banks, assign all or any portion of its Commitment, and the Advances, participations in Letters of Credit and Swingline Advances owing to any of the Banks listed on the signature pages hereof, any Additional Lender that shall become a party hereto pursuant to Section 8.7(a)(i), any Affiliate of such a Lender or any Approved Fund that is an Affiliate of a Lender. No such assignment, other than to any of the Banks listed on the signature pages hereof, any Additional Lender that shall become a party hereto pursuant to Section 8.7(a)(i), any Affiliate of such a Lender or any Approved Fund that is an Affiliate of a Lender shall release the assigning Lender from its obligations hereunder.

(iii) By executing and delivering a Lender Assignment, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Lender Assignment, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in

72


connection with any Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any other instrument or document furnished pursuant thereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under any Loan Document or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of each Loan Document, together with copies of the financial statements referred to in Section 4.1(f)) hereof and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Lender Assignment; (iv) such assignee will, independently and without reliance upon the Agent, such assigning Lender 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 the Loan Documents; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to the Agent by the terms thereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Loan Documents are required to be performed by it as a Lender.

(iv) No such assignment shall be made to (i) the Borrower or any of the Borrower's Affiliates or Subsidiaries, (ii) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (ii), or (iii) a natural Person.

(v) In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or sub-participations, or other compensating actions, including funding, with the consent of the Borrower and the Agent, the applicable pro rata share of Advances previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (i) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Agent, each LC Issuing Bank, the Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (ii) acquire (and fund as appropriate) its full pro rata share of all Advances and participations in Letters of Credit and Swingline Advances. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

73


(b) The Agent shall maintain at its address referred to in Section 8.2 a copy of each Lender Assignment delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Advances owing to, each Lender from time to time (the "Register"). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. In addition, the Agent shall maintain on the Register information regarding the designation, revocation of designation, of any Lender as a Designated Lender. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice. Upon its receipt of a Lender Assignment executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with any Note or Notes (if any) subject to such assignment, the Agent shall, if such Lender Assignment has been completed and is in substantially the form of Exhibit 8.7 hereto, (i) accept such Lender Assignment, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower.

(c) Participations. Each Lender may sell participations to any Person (other than a natural Person or the Borrower or any of the Borrower's Affiliates or Subsidiaries) (each, a "Participant") all or a portion of its rights and obligations under the Loan Documents (including, without limitation, all or a portion of its Commitment, the Advances owing to it, its participations in Letters of Credit or Swingline Advances, and the Note or Notes (if any) held by it); provided, however, that (i) such Lender's obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Note (if any) for all purposes of this Agreement, and (iv) the Borrower, the Agent, the LC Issuing Banks and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that affects such Participant. The Borrower agrees that each Participant, solely pursuant to the terms of the relevant agreement or instrument between such Participant and the participating Lender and not as a party or third party beneficiary to this Agreement, shall be entitled to the benefits of Section 2.13, Section 2.14, Section 8.4(d), and Section 2.17 (subject to the requirements and limitations therein, including the requirements under Section 2.17(e) (it being understood that the documentation required under Section 2.17(e) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section 8.7(c); provided that such Participant (A) agrees to be subject to the provisions of Section 2.20 as if it were an assignee under paragraph (b) of this Section 8.7(c); and (B) shall not be entitled to receive any greater payment under Section 2.14 or Section 2.17 with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. No Participant shall be deemed to be a party to or have standing under this Agreement, and shall only act through the participating Lender pursuant to the terms of the relevant agreement or instrument between such Participant

74


and the participating Lender. Each Lender that sells a participation agrees to cooperate with the Borrower to effectuate the provisions of Section 2.20(a) with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 2.18 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.18 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower solely for purposes of complying with Section 5f.103-1(c) of the United States Treasury Regulations, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant's interest in the Advances or other obligations under the Loan Documents (the "Participant Register"); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is (i) necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations, (ii) required by a regulatory agency with jurisdiction over the party requesting disclosure or (iii) required by applicable law. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register.

(d) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.7, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant shall agree, in accordance with the terms of Section 8.8, to preserve the confidentiality of any Confidential Information relating to the Borrower received by it from such Lender.

(e) Anything in this Section 8.7 to the contrary notwithstanding, any Lender may assign a security interest in or pledge all or any portion of its Commitment and the Advances owing to it to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder or substitute any such pledge or assignee for such Lender as a party hereto.

Section 8.8 Confidentiality. In connection with the negotiation and administration of this Agreement and the other Loan Documents, the Borrower has furnished and will from time to time furnish to a Recipient written information which is identified to the Recipient in writing, when delivered, as confidential (such information, other than any such information which (i) as publicly available, or otherwise known to the Recipient, at the time of disclosure, (ii) subsequently becomes publicly available other than through any act or omission by the Recipient or (iii) otherwise subsequently becomes known to the Recipient other than through a Person whom the Recipient knows to be acting in violation of his or its obligations to the Borrower, being hereinafter referred to as "Confidential Information"). The Recipient will maintain the confidentiality of any Confidential Information in accordance with such procedures as the

75


Recipient applies generally to information of that nature. It is understood, however, that the foregoing will not restrict the Recipient's ability to freely exchange such Confidential Information with its Affiliates or with current or prospective participants in or assignees of, or any current or prospective counterparty (or its advisors) to any swap, securitization or derivative transaction relating to, the Recipient's position herein, but the Recipient's ability to so exchange Confidential Information shall be conditioned upon any such Affiliate's or prospective participant's or assignee's or counterparty's entering into an understanding as to confidentiality similar to this provision. It is further understood that the foregoing will not prohibit the disclosure of any or all Confidential Information if and to the extent that such disclosure may be required (i) by a regulatory agency or otherwise in connection with an examination of the Recipient's records by appropriate authorities, (ii) pursuant to court order, subpoena or other legal process or in connection with any pending or threatened litigation, (iii) otherwise as required by law, or (iv) in order to protect its interests or its rights or remedies hereunder or under the other Loan Documents; in the event of any required disclosure under clause (ii) or (iii) above, the Recipient agrees to use reasonable efforts to inform the Borrower as promptly as practicable to the extent legally permitted to do so.

(v) the by-laws of the Borrower and all amendments thereto (the "Borrower By-laws").

In addition, we have examined the originals, or copies certified to our satisfaction, of such other corporate records of the Borrower, certificates of public officials and of officers of the Borrower, and agreements, instruments and other documents, as we have deemed necessary as a basis for the opinions expressed below. As to questions of fact material to such opinions, we have, when relevant facts were not independently established by us, relied upon certificates of the Borrower or its officers, or of public officials.


We have assumed (i) the due execution and delivery, pursuant to due authorization, of the Credit Agreement by all parties to the Credit Agreement (other than the Borrower), (ii) the authenticity of all such documents submitted to us as originals, (iii) the genuineness of all signatures, (iv) the conformity to the originals of all such documents submitted to us as copies and (v) the enforceability of all documents against parties thereto other than the Borrower.

Our opinions expressed herein are limited to the laws of the State of New York, the laws of the State of Colorado and the Federal laws of the United States of America in effect on the date hereof as they presently apply and we express no opinion as to the laws of any other jurisdiction. We authorize Robinson, Bradshaw & Hinson, P.A., special counsel to the Agent, to rely on this opinion.

Based upon the foregoing, but subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that:

1. Based solely upon a certificate issued by the Wisconsin Department of Financial Institutions, the Borrower is a validly existing corporation, has filed its most recent annual report required by the Wisconsin Statutes and has not filed Articles of Dissolution as of the date of such certificate.

2. The execution, delivery and performance by the Borrower of the Credit Agreement, the Notes and the Fee Letters are within the Borrower's corporate powers, have been duly authorized by all necessary corporate action, and do not contravene (a) the Borrower Charter or the Borrower By-laws, or (b) any law, rule or regulation of which we have knowledge applicable to the Borrower. The Credit Agreement, the Notes and the Fee Letters have been duly executed and delivered on behalf of the Borrower. It is understood that the Borrower is required to obtain the Commitment Increase Approvals before any Commitment Increase.

3. Other than the Approval of the Public Service Commission of Wisconsin, no Governmental Approval is required in connection with the execution, delivery or performance by the Borrower of any Loan Document, or the enforcement thereof by the Agent and the Lenders.

4. The Credit Agreement, the Notes and the Fee Letters are the legal, valid and binding obligations of the Borrower, enforceable against the Borrower in accordance with their respective terms.

5. The Borrower is not an "investment company" as defined in the Investment Company Act of 1940, as amended.

Wherever we indicate that our opinion with respect to the existence or absence of facts is "to our knowledge" or the like, our opinion is, with your permission, based solely on certificates of the Borrower and the current conscious awareness of facts or other information of the attorneys currently with our firm who have represented the Borrower or any Subsidiary in connection with the transactions contemplated by the Credit Agreement mean the conscious awareness of facts or other information by the lawyers in this firm participating in the preparation of this opinion and representing Borrower or any Guarantor in the transactions contemplated hereby (Michael W. King, Esq. and Jonathan S. Sar, Esq.).


Our opinion set forth in paragraph 4 above is limited by:

(a)

Applicable bankruptcy, receivership, reorganization, insolvency, moratorium, fraudulent conveyance or transfer, and other laws and judicially developed doctrines relating to or affecting creditors' rights and remedies generally;

(b)

General principles of equity, regardless of whether such enforcement is considered in a proceeding in equity or at law, and limitations on the availability of specific performance, injunctive relief and other equitable remedies;

(c)

The possibility that certain rights, remedies, waivers, and other provisions of the Loan Documents may not be enforceable; nevertheless, such unenforceability will not render any of the Loan Documents invalid as a whole or preclude (i) judicial enforcement of the obligation of Borrower to repay the principal, together with interest thereon (to the extent not deemed a penalty) as provided in the Credit Agreement and/or the Notes; or (ii) acceleration of the obligation of Borrower to repay such principal, together with such interest, upon a material default in a material provision of the Loan Documents; and

(d)

The requirement that the enforcing party act in a commercially reasonable manner and in good faith in exercising its rights under the Loan Documents.

These opinions are given as of the date hereof, they are intended to apply only to those facts and circumstances that exist as of the date hereof, and we assume no obligation or responsibility to update or supplement these opinions to reflect any facts or circumstances that may hereafter come to our attention or any changes in laws that may hereafter occur, or to inform the addressee of any change in circumstances occurring after the date hereof that would alter the opinions rendered herein.

This opinion is limited to the matters set forth herein, and no opinion may be inferred or implied beyond the matters expressly contained herein. Except as expressly set forth herein, this opinion is being provided solely for the purpose of complying with the requirements of the Agent and the Lenders in connection with the Credit Agreement, and is being rendered solely for the benefit of the addressees hereof, their participants, assignees and transferees. This opinion may not be used or relied upon for any other purpose, relied upon by any other party, or filed with or disclosed to any governmental authority other than a court in connection with the enforcement or protection of the rights or remedies of the Agent and/or the Lenders under the Credit Agreement or to a banking examiner or regulator in connection with an examination of the Agent and/or the Lenders by such governmental authority, without our prior written consent.

Very truly yours,

Re:

Alliant Energy Corporation

Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 3.l(a)(viii)(B) of the Third Amended and Restated Five Year Credit Agreement, dated as of December __, 2011 (the "Credit Agreement"), among Alliant Energy Corporation (the "Borrower"), the Banks parties thereto and Wells Fargo Bank, National Association, as Administrative Agent, Swingline Lender and as LC Issuing Bank. Terms defined in the Credit Agreement and not otherwise defined herein are used herein as therein defined.

I am Senior Attorney for the Borrower and have acted as such in connection with the preparation, execution and delivery of, and the closing on this date of, the Credit Agreement and the other Loan Documents.

In that capacity I have examined, or have arranged for the examination by an attorney or attorneys under my general supervision of:

(i) the Credit Agreement;

(ii) the Notes delivered in connection with the closing of the Credit Agreement;

(iii) the Fee Letters;

(iv) the Articles of Incorporation of the Borrower and all amendments thereto (the "Borrower Charter"); and

(v) the by-laws of the Borrower and all amendments thereto (the "Borrower By-laws").

In addition, I, or an attorney or attorneys under my general supervision, have examined the originals, or copies certified to my or their satisfaction, of such other corporate records of the Borrower, certificates of public officials and of officers of the Borrower, and agreements, instruments and other documents, as I or such attorneys have deemed necessary as a basis for the opinions expressed below. As to questions of fact material to such opinions, I or such attorneys have, when relevant facts were not independently established by me or by them, relied upon certificates of the Borrower or its officers or of public officials.


I have assumed (i) the due execution and delivery, pursuant to due authorization, of the Credit Agreement by all parties to such document (other than the Borrower), (ii) the authenticity of all such documents submitted to me as originals, (iii) the genuineness of all signatures (other than those of the Borrower) and (iv) the conformity to the originals of all such documents submitted to me as copies.

I, or an attorney or attorneys under my general supervision, have made such examination of law as in my or their judgment is necessary or appropriate for purposes of this opinion. I and such attorneys do not, however, purport to be qualified to pass upon, and express no opinion as to, the laws of any jurisdiction other than the laws of the State of Wisconsin.

Based upon and subject to the foregoing, I am of the opinion that:

1. The Borrower is a corporation duly organized, validly existing and in good standing under the laws of the State of Wisconsin and is duly qualified to do business in, and is in good standing in, all other jurisdictions where the nature of its business or the nature of the property owned or leased by it makes such qualification necessary, except where the failure to so qualify would not have a material adverse affect on the business, financial condition, results of operations or prospects of the Borrower and its Subsidiaries, taken as a whole.

2. The execution, delivery and performance by the Borrower of the Credit Agreement, the Notes and the Fee Letters are within the Borrower's corporate powers, have been duly authorized by all necessary corporate action, and do not contravene (a) the Borrower Charter or the Borrower By-laws; (b) any law, rule, regulation, order or judgment applicable to the Borrower; (c) any contractual restriction arising under any agreement or instrument evidencing indebtedness described in Schedule III of the Credit Agreement; or (d) to my knowledge, any other legal or contractual restriction binding on, or affecting the Borrower or its properties; and such execution, delivery and performance do not result in or require the creation or imposition of any Lien upon or with respect to any of its properties under any agreement or instrument evidencing indebtedness described in Schedule III of the Credit Agreement or, to my knowledge, under any other agreement or instrument. The Credit Agreement, the Notes and the Fee Letters have been duly executed and delivered on behalf of the Borrower.

3. No Governmental Approval is required in connection with the execution, delivery or performance by the Borrower of any Loan Document.

4. There is no pending or, to my knowledge, threatened action or proceeding affecting the Borrower or its properties before any court, governmental agency or arbitrator, that could reasonably be expected, if adversely determined, to materially and adversely affect the business, financial condition, operations, results of operations or prospects of the Borrower, or affect the legality, validity or enforceability of the Credit Agreement or any other Loan Document.


I authorize Brownstein Hyatt Farber Schreck, LLP, special counsel to the Borrower, to rely on this opinion respecting matters covered by or relating to the laws of the State of Wisconsin.

Very truly yours,

Jake C. Blavat

Senior Attorney
