Each such notice of a Contract Borrowing (a "Notice of Contract Borrowing") shall be in substantially the form of Exhibit A-1 hereto, specifying therein the requested (i) date of such Contract Borrowing, (ii) Type of Contract Advances comprising such Contract Borrowing, (iii) aggregate amount of such Contract Borrowing and (iv) Interest Period. Each Bank shall, before 12:00 noon (New York City time) on the date of any such Contract Borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent at its address referred to in Section 8.02, in same day funds, such Bank's ratable portion of such Contract Borrowing. Upon the Administrative Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower at the Administrative Agent's aforesaid address. (b) Each Notice of Contract Borrowing shall be irrevocable and binding on the Borrower. In the case of any Contract Borrowing which the related Notice of Contract Borrowing specifies is to be comprised of Eurodollar Rate Contract Advances or Adjusted CD Rate Advances, the Borrower shall indemnify each Bank against any loss, cost, or expense incurred by such Bank as a result of any failure by the Borrower to complete such Borrowing (whether or not due to a failure to fulfill on or before the date specified in such Notice of Contract Borrowing the applicable conditions set forth in Article III), such losses, costs, and expenses to include, without limitation, any loss (including loss of anticipated profits), cost, or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to fund the Contract Advance to be made by such Bank as part of such Contract Borrowing when such Contract Advance, as a result of such failure, is not made on such date. (c) Unless the Administrative Agent shall have received notice from a Bank prior to the date of any Contract Borrowing that such Bank will not make available to the Administrative Agent such Bank's ratable portion of such Contract Borrowing, the Administrative Agent may assume that such Bank has made such portion available to the Administrative Agent on the date of such Contract Borrowing in accordance with Section 2.02(a) and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made such ratable portion available to 10 the Administrative Agent, such Bank and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Contract Advances comprising such Contract Borrowing and (ii) in the case of such Bank, an interest rate equal at all times to the Federal Funds Effective Rate. If such Bank shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Bank's Contract Advance as part of such Contract Borrowing for purposes of this Agreement. (d) The failure of any Bank to make the Contract Advance to be made by it as part of any Contract Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make its Contract Advance on the date of such Contract Borrowing, but no Bank shall be responsible for the failure of any other Bank to make the Contract Advance to be made by such other Bank on the date of any Contract Borrowing. SECTION 2.03 The Competitive Advances. (a) Each Bank severally agrees that the Borrower may make Competitive Borrowings under this Section 2.03 from time to time on any Business Day during the period from the Closing Date until the Termination Date, in each case on the terms and conditions hereinafter set forth; provided, however, that at no time shall the aggregate amount of Contract Advances and Competitive Advances outstanding exceed the aggregate amount of the Commitments. Each Competitive Borrowing shall consist of Competitive Advances of the same Type made on the same day. (i) The Borrower may request a Competitive Borrowing under this Section 2.03 by delivering to the Administrative Agent and Auction Administration Agent, (A) in the case of a Borrowing consisting of Fixed Rate Competitive Advances, by not later than 10:30 a.m. (New York City time) one Business Day prior to the day of the proposed Competitive Borrowing, and (B) in the case of a Borrowing consisting of Eurodollar Rate Competitive Advances, by not later than 10:30 a.m. (New York City time) on the fourth Business Day prior to the date of the proposed Competitive Borrowing, a notice of a Competitive Borrowing (a "Notice of Competitive Borrowing"), in substantially the form of Exhibit A-2 hereto, specifying the proposed (1) date of such Competitive Borrowing, (2) Type of Competitive Advances comprising such Competitive Borrowing, (3) aggregate amount, which shall not be less than $10,000,000 or an integral multiple of $1,000,000 in excess thereof) of such Competitive Borrowing, (4) maturity date for repayment of each Competitive Advance to be made as part of such Competitive Borrowing (which maturity date shall be, in the case of a Fixed Rate Competitive Borrowing, not earlier than seven days after the date of such Borrowing, and, in the case of a Eurodollar Rate Competitive Borrowing, not later than 1 month or 2, 3 or 6 months after the date of such Borrowing, as the Borrower shall elect) and (5) any other terms to be applicable to such Competitive Borrowing. The Auction Administration Agent shall in turn promptly deliver (by cable or telecopy) to each Bank a notice of competitive bid request, in substantially the form of Exhibit A-3, notifying the Banks of each request for a Competitive Borrowing received by it from the Borrower and of the terms contained in such Notice of Competitive Borrowing. (ii) Each Bank shall, if, in its sole discretion, it elects to do so, irrevocably offer to make one or more Competitive Advances to the Borrower as part of such proposed Competitive Borrowing at a rate or rates of interest specified by such Bank in its sole discretion, by notifying (by telecopy, cable or telephone [in the case of telephone, immediately confirmed by telecopy]) the Auction Administration Agent (which shall give prompt notice thereof to the Borrower), (A) in the case of a Fixed Rate Competitive Borrowing, before 10:00 a.m. (New York City time) on the date of such proposed Competitive Borrowing specified in the Notice of Competitive Borrowing delivered with respect thereto, and (B) in the case of a Eurodollar Rate Competitive Borrowing, before 10:00 a.m. (New York City time) on the third Business Day prior to the date of such proposed Competitive Borrowing specified in the Notice of Competitive Borrowing delivered with respect thereto, of the maximum amount of each Competitive Advance which such Bank would be 11 willing to make as part of such proposed Competitive Borrowing (which amount may, subject to the proviso to the first sentence of this Section 2.03(a), exceed such Bank's Commitment), the rate or rates of interest therefor (and whether reserves are included therein) and such Bank's Applicable Lending Office with respect to each such Competitive Advance and any other terms and conditions required by such Bank; provided that, if Auction Administration Agent in its capacity as a Bank shall, in its sole discretion, elect to make any such offer, it shall notify the Borrower of such offer before 9:45 a.m. (New York City time) on the date specified herein for notice of offers by the other Banks. Each competitive bid shall be submitted by a Bank to the Auction Administration Agent on a competitive bid form substantially similar to Exhibit A-4. If any Bank shall fail to notify the Auction Administration Agent, before the time specified herein for notice of offers, that it elects to make such an offer, such Bank shall be deemed to have elected not to make such an offer, and such Bank shall not be obligated or entitled to, and shall not, make any Competitive Advance as part of such Competitive Borrowing. If any Bank shall provide telephonic notice to the Auction Administration Agent of its election to make an offer, but such telephonic notice has not been confirmed by telecopy to the Auction Administration Agent at or before the time specified herein for notice of offers, the Auction Administration Agent may, in its sole discretion and without liability to such Bank or the Borrower, elect whether or not to provide notice thereof to the Borrower. (iii) The Borrower shall, in turn, (A) in the case of a Fixed Rate Competitive Borrowing, before 11:00 a.m. (New York City time) on the date of such proposed Competitive Borrowing specified in the Notice of Competitive Borrowing delivered with respect thereto, and (B) in the case of a Eurodollar Rate Competitive Borrowing, before 11:00 a.m. (New York City time) on the third Business Day prior to the date of such proposed Competitive Borrowing specified in the Notice of Competitive Borrowing delivered with respect thereto, either: (A) cancel such proposed Competitive Borrowing by giving the Auction Administration Agent notice to that effect, or (B) accept one or more of the offers made by any Bank or Banks pursuant to paragraph (ii) above, in its sole discretion, by giving notice to the Auction Administration Agent of the amount of each Competitive Advance (which amount shall be equal to or greater than $1,000,000, and equal to or less than the maximum amount offered by such Bank, notified to the Borrower by the Auction Administration Agent on behalf of such Bank for such Competitive Advance pursuant to paragraph (ii) above) to be made by each Bank as part of such Competitive Borrowing, and reject any remaining offers made by Banks pursuant to paragraph (ii) above, by giving the Auction Administration Agent notice to that effect; provided, however, that the aggregate amount of such offers accepted by the Borrower shall be equal at least to $10,000,000 or an integral multiple of $1,000,000 in excess thereof. Each such notice of competitive bid acceptance/rejection from the Borrower shall be in a form substantially similar to Exhibit A-5. (iv) If the Borrower notifies the Auction Administration Agent that such Competitive Borrowing is canceled pursuant to paragraph (iii)(A) above, the Auction Administration Agent shall give prompt notice (by cable or telecopy) thereof to the Banks, and such Competitive Borrowing shall not be made. (v) If the Borrower accepts one or more of the offers made by any Bank or Banks pursuant to paragraph (iii)(B) above, such offer or offers and the Notice of Competitive Borrowing in respect thereof shall constitute a supplement to this Agreement in respect of such Competitive Borrowing and the Competitive Advances made pursuant thereto, and the Auction Administration Agent shall in turn promptly notify (A) each Bank that has made an offer as described in paragraph (ii) above of the date and aggregate amount of such Competitive Borrowing, the interest rate thereon, and whether or not any offer or offers made by such Bank pursuant to paragraph (ii) above 12 have been accepted by the Borrower, and (B) each Bank that is to make a Competitive Advance as part of such Competitive Borrowing (a "Participating Bank" as to such Competitive Borrowing) of the amount of each Competitive Advance to be made by such Bank as part of such Competitive Borrowing and the maturity date for the repayment of each such Competitive Advance (together with a confirmation of the Auction Administration Agent's understanding of the interest rate and any other terms applicable to each such Competitive Advance; the Auction Administration Agent shall assume, unless notified by such Bank to the contrary, that its understanding of such information is correct). Each such Participating Bank shall, before 12:00 noon (New York City time) on the date of such Competitive Borrowing specified in the notice received from the Auction Administration Agent pursuant to clause (A) of the preceding sentence, make available for the account of its Applicable Lending Office to the Administrative Agent (at its address referred to in Section 8.02) such Bank's portion of such Competitive Borrowing, in same-day funds. Upon fulfillment of the applicable conditions set forth in Article III and after receipt by the Administrative Agent of such funds, the Administrative Agent will make such funds available to the Borrower at the Administrative Agent's aforesaid address. Promptly after each Competitive Borrowing, the Auction Administration Agent will notify each Bank of the amount of the Competitive Borrowing, such Bank's Competitive Reduction resulting therefrom, and the date upon which such Competitive Reduction commenced and is anticipated to terminate. (b) Within the limits and on the conditions set forth in this Section 2.03, the Borrower may from time to time borrow under this Section 2.03, repay pursuant to Section 2.07(b), prepay under Section 2.07(c), and reborrow under this Section 2.03. SECTION 2.04 Conversion and Continuation of Contract Borrowings. The Borrower shall have the right at any time upon prior irrevocable notice to the Administrative Agent (i) not later than 12:00 noon (New York City time), one Business Day prior to conversion, to convert any Borrowing consisting of Eurodollar Rate Contract Advances or Adjusted CD Rate Advances into a Borrowing consisting of Alternate Base Rate Advances, (ii) not later than 10:00 a.m. (New York City time), two Business Days prior to conversion or continuation, to convert any Borrowing consisting of Eurodollar Rate Contract Advances or Alternate Base Rate Advances into a Borrowing consisting of Adjusted CD Rate Advances or to continue any Borrowing consisting of Adjusted CD Rate Advances for an additional Interest Period, (iii) not later than 10:00 a.m. (New York City time), three Business Days prior to conversion or continuation, to convert any Borrowing consisting of Alternate Base Rate Advances or Adjusted CD Rate Advances into a Borrowing consisting of Eurodollar Rate Contract Advances or to continue any Borrowing consisting of Eurodollar Contract Advances for an additional Interest Period, (iv) not later than 10:00 a.m. (New York City time), three Business Days prior to conversion, to convert the Interest Period with respect to any Borrowing consisting of Eurodollar Rate Contract Advances to another permissible Interest Period, and (v) not later than 10:00 a.m. (New York City time), two Business Days prior to conversion, to convert the Interest Period with respect to any Borrowing consisting of Adjusted CD Rate Advances to another permissible Interest Period, subject in each case to the following: (a) each conversion or continuation shall be made pro rata among the Banks in accordance with the respective principal amounts of the Advances comprising the converted or continued Contract Borrowing; (b) if less than all the outstanding principal amount of any Contract Borrowing shall be converted or continued, the aggregate principal amount of such Contract Borrowing converted or continued shall be an amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof; (c) accrued interest on an Advance (or portion thereof) being converted shall be paid by the Borrower at the time of conversion; (d) if any Borrowing consisting of Eurodollar Rate Contract Advances or Adjusted CD Rate Advances is converted at a time other than the end of the Interest Period applicable thereto, the Borrower shall pay, upon demand, any amounts due to the Banks pursuant to Section 8.04(b) as a result of such conversion; 13 (e) any portion of a Contract Borrowing maturing or required to be repaid in less than one month may not be converted into or continued as a Borrowing consisting of Eurodollar Rate Contract Advances; (f) any portion of a Borrowing maturing or required to be repaid in less than 30 days may not be converted into or continued as a Borrowing consisting of Adjusted CD Rate Advances; (g) any portion of a Borrowing consisting of Eurodollar Rate Contract Advances or Adjusted CD Rate Advances which cannot be converted into or continued as such by reason of clauses (e) and (f) above shall be automatically converted at the end of the Interest Period in effect for such Borrowing into a Borrowing consisting of Alternate Base Rate Advances; and (h) no Interest Period may be selected for any Borrowing consisting of Eurodollar Rate Contract Advances or Adjusted CD Rate Advances that would end later than the Maturity Date. Each notice pursuant to this Section 2.04 shall be irrevocable and shall refer to this Agreement and specify (i) the identity and amount of the Contract Borrowing that the Borrower requests be converted or continued, (ii) whether such Contract Borrowing is to be converted to or continued as a Borrowing consisting of Eurodollar Rate Contract Advances, Adjusted CD Rate Advances, or Alternate Base Rate Advances, (iii) if such notice requests a conversion, the date of such conversion (which shall be a Business Day), and (iv) if such Contract Borrowing is to be converted to or continued as a Borrowing consisting of Eurodollar Rate Contract Advances or Adjusted CD Rate Advances, the Interest Period with respect thereto. If no Interest Period is specified in any such notice with respect to any conversion to or continuation as a Borrowing consisting of Eurodollar Rate Contract Advances or Adjusted CD Rate Advances, the Borrower shall be deemed to have selected an Interest Period of one month's duration, in the case of a Borrowing consisting of Eurodollar Rate Contract Advances, or 30 days' duration, in the case of a Borrowing consisting of Adjusted CD Rate Advances. The Administrative Agent shall advise the other Banks of any notice given pursuant to this Section 2.04 and of each Bank's portion of any converted or continued Contract Borrowing. If the Borrower shall not have given notice in accordance with this Section 2.04 to continue any Contract Borrowing into a subsequent Interest Period (and shall not otherwise have given notice in accordance with this Section 2.04 to convert such Contract Borrowing), such Contract Borrowing shall, at the end of the Interest Period applicable thereto (unless repaid pursuant to the terms hereof), automatically be continued into a new Interest Period as a Borrowing consisting of Alternate Base Rate Advances. SECTION 2.05 Fees. (a) Facility Fees. Borrower shall pay to each Bank, through the Administrative Agent, a facility fee on the average daily amount of the Commitment of such Bank (whether used or unused) for the period from and including the Closing Date, up to but excluding the Termination Date at a rate per annum equal to the Applicable Margin for Facility Fees. Accrued facility fees shall be payable in arrears, commencing on the last day of the calendar quarter in which the Closing Date occurs, and thereafter, quarterly on the last day of each March, June, September, and December and on the Termination Date. (b) Fees of Administrative Agent and Chase Securities Inc. Borrower shall pay to Administrative Agent and Chase Securities Inc., solely for their own respective accounts, the fees described in the separate letter agreement dated November 5, 1997, among the Borrower, Administrative Agent, and Chase Securities Inc. on the dates specified therein. SECTION 2.06 Optional Reduction of the Commitments. The Borrower shall have the right, upon at least two Business Days' irrevocable notice to the Administrative Agent, to terminate in whole or reduce ratably in part the respective Commitments of the Banks; provided, however, that (i) each partial reduction shall be in the aggregate amount of $10,000,000 or in an integral multiple of $1,000,000 in excess thereof, and (ii) no such termination or reduction shall be made which would reduce the Commitments to an amount less than the aggregate outstanding principal amount of the Advances. The Administrative Agent shall promptly thereafter notify each Bank of such termination or reduction. 14 SECTION 2.07 Repayment of Advances; Prepayment. (a) The Borrower shall repay to the Administrative Agent for the account of each Bank the principal amount of each Contract Advance made by each Bank on the Maturity Date. (b) The Borrower shall repay to the Administrative Agent, for the account of each Participating Bank which has made a Competitive Advance, on the maturity date of each Competitive Advance (such maturity date being that specified by the Borrower for repayment of such Competitive Advance in the Notice of Competitive Borrowing delivered with respect thereto) the then unpaid principal amount of such Competitive Advance. (c) The Borrower may, on notice given to the Administrative Agent (i) in the case of Alternate Base Rate Advances, not later than 10:30 a.m. (New York City time) on the day of the proposed prepayment, and (ii) in the case of Adjusted CD Rate Advances and Eurodollar Rate Contract Advances, not later than 10:30 a.m. (New York City time) on the second Business Day prior to the day of the proposed prepayment, stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given, the Borrower shall, prepay the outstanding principal amounts of the Contract Advances constituting part of the same Contract Borrowing in whole or ratably in part; provided, however, that any such partial prepayment shall be in an aggregate principal amount not less than $10,000,000, or in an integral multiple of $1,000,000 in excess thereof, and provided further, that any such prepayment of Adjusted CD Rate Advances or Eurodollar Rate Contract Advances shall be subject to the provisions of Section 8.04(b) hereof. The Borrower may not prepay any principal amount of any Competitive Advance unless the Participating Bank making such Competitive Advance shall have expressly agreed thereto. The Administrative Agent shall promptly notify each Bank of any prepayments pursuant to this Section 2.07(c) promptly after any such prepayment. The Borrower shall have no right to prepay any principal amount of any Advance except as expressly set forth in this Section 2.07(c). SECTION 2.08 Interest. The Borrower shall pay interest on each Advance made by each Bank from the date of such Advance until paid in full, at the following rates per annum: (i) Contract Advances. If such Advance is a Contract Advance, the Applicable Rate from time to time for such Contract Advance from the date of such Advance until the last day of the last Interest Period therefor, payable on the last day of each Interest Period and, in the case of any Interest Period longer than 90 days (in the case of Adjusted CD Rate Advances) or three months (in the case of Eurodollar Rate Contract Advances), on such 90th day or the last day of such three-month period, as the case may be. (ii) Competitive Advances. If such Advance is a Competitive Advance, a rate per annum equal at all times from the date of such Advance until the maturity thereof to the rate of interest for such Competitive Advance specified by the Participating Bank making such Competitive Advance in its notice with respect thereto delivered pursuant to Section 2.03 (a)(ii) above, payable on the proposed maturity date specified by the Borrower for such Competitive Advance in the related Notice of Competitive Borrowing delivered pursuant to Section 2.03 (a)(i) above; provided, that in the case of Advances with maturities of greater than three months, interest shall be payable at the end of each three-month period for such Advance. (iii) Default Amounts. In the case of any past-due amounts of the principal of, or (to the fullest extent permitted by law) interest on, any Advance, from the date such amount becomes due until paid in full, payable on demand, a rate per annum equal at all times to 2% above the Alternate Base Rate in effect from time to time. SECTION 2.09 Alternate Rate of Interest. If Banks having more than 66-2/3% of the Commitments shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent that the Eurodollar Rate for any Eurodollar Rate Advances or the Adjusted CD Rate for any Adjusted CD Rate Advances comprising such Borrowing will not adequately reflect the cost to such Banks of making or funding their respective 15 Advances for such Borrowing, the right of the Borrower to select Advances of such Type for such Borrowing or any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist, and (i) any request by the Borrower for a Eurodollar Rate Competitive Advance shall be of no force and effect and shall be denied by the Administrative Agent and (ii) any request by the Borrower for a Eurodollar Rate Contract Advance or an Adjusted CD Rate Advance shall be deemed to be a request for an Alternate Base Rate Advance. SECTION 2.10 Optional Renewal of Commitments. (a) Optional Renewal Procedures. Borrower may request that the Maturity Date be extended for all or a portion of the Commitments to a date which is no later than the 364th day after the then-current Maturity Date; provided that, any such extension request shall be made in writing (an "Extension Request") by Borrower and delivered to Administrative Agent no more than 30 days prior to (but no later than 20 days prior to) the then-current Maturity Date. Promptly upon receipt of an Extension Request, Administrative Agent shall notify Banks of such request. (i) Banks' Response to Extension Request. The Banks may, at their option, accept or reject such Extension Request by giving written notice to Administrative Agent delivered no earlier than 20 days prior to (but no later than 10 days prior to) the then-effective Maturity Date (the "Response Date"). If any Bank shall fail to give such notice to Administrative Agent by the Response Date, such Bank shall be deemed to have rejected the requested extension. If the Extension Request is not consented to by Banks holding at least 51% of the Commitments by the Response Date, the Extension Request will be rejected, and the Commitments will terminate on the then-current Maturity Date. If the Banks holding at least 51% of the Commitments consent to the Extension Request by the Response Date, the Maturity Date for those Banks consenting to the extension (for purposes of this Section 2.10(a), the "Accepting Banks") shall be automatically extended to the date which is the 364th day after the then-current Maturity Date. (ii) Additional Procedures to Extend the Rejected Amount. If the Extension Request is consented to by Banks holding not less than 51% of the Commitments, but fewer than all Banks (any Bank not consenting to the Extension Request being referred to in this Section 2.10(a) as a "Rejecting Bank"), then Administrative Agent shall, within 48 hours of making such determination, notify the Accepting Banks and Borrower of the aggregate Commitments held by the Rejecting Banks (as used in this Section 2.10(a), the "Rejected Amount"). Each Accepting Bank shall have the right, but not the obligation, to elect to increase its respective Commitments by an amount not to exceed the Rejected Amount, which election shall be made by notice from each Accepting Bank to the Administrative Agent given not later than five days after the date notified by Administrative Agent, specifying the amount of such proposed increase in such Accepting Bank's Commitment. If the aggregate amount of the proposed increases in the Commitments of all Accepting Banks making such an election does not equal or exceed the Rejected Amount, then Borrower shall have the right to add one or more financial institutions (which are not Rejecting Banks and which are Eligible Assignees) as Banks (as used in this Section 2.10(a), a "Purchasing Bank") to replace such Rejecting Banks, which Purchasing Banks shall have aggregate Commitments not greater than those of the Rejecting Banks (less any increases in the Commitments of Accepting Banks, as described in the following clause (iii)). The transfer of Commitments and outstanding Borrowings from Rejecting Banks to Purchasing Banks or Accepting Banks shall take place on the effective date of, and pursuant to the execution, delivery, and acceptance of, an Assignment and Acceptance in accordance with the procedures set forth in Section 8.07. (iii) Adjustments to, and Terminations of, Commitments. (A) If less than 100% of the Commitments are extended (whether by virtue of Borrower's failure to request an extension of the total Commitments or by virtue of any Bank not consenting to any Extension Request), then the Commitments shall automatically 16 be reduced on the Maturity Date on which the applicable approved extension is effective by an amount equal to (as the case may be) (i) the portion of the Commitments not requested to be extended by Borrower in its Extension Request or (ii) the amount of the Rejected Amount (to the extent not replaced by Accepting Banks or Purchasing Banks pursuant to the procedures set forth in the foregoing Section 2.10(a)(ii)). Each Rejecting Bank shall have no further obligation or Commitment following the Maturity Date on which the applicable approved extension is effective, other than any obligation accruing prior to such date as provided herein. (B) If the aggregate amount of the proposed increases in the Commitments of all Accepting Banks making an election to increase their respective Commitments is in excess of the Rejected Amount, then (i) the Rejected Amount shall be allocated pro rata among such Accepting Banks based on the respective amounts of the proposed increases to Commitments elected by such Accepting Banks; and (ii) the respective Commitments of each such Accepting Bank shall be increased by the respective amount allocated pursuant to clause (i) of this Section 2.10(a)(iii)(B), such that, after giving effect to the approved extensions and all such terminations and increases, no reduction will occur in the aggregate amount of the Commitments. (C) If the aggregate amount of the proposed increases to the Commitments of all Accepting Banks making such an election to so increase their respective Commitments equals the Rejected Amount, then the respective Commitments of such Accepting Banks shall be increased by the respective amounts of their proposed increases, such that, after giving effect to the approved extensions and all such terminations and increases, no reduction will occur in the aggregate amount of the Commitments. (D) If the aggregate amount of the proposed increases to the Commitments of all Accepting Banks making such an election is less than the Rejected Amount, then (i) the respective Commitments of each such Accepting Bank shall be increased by the respective amount of its proposed increase; and (ii) the amount of the Commitments shall be reduced by the amount of the Rejected Amount (to the extent not replaced by the Accepting Banks or the Purchasing Banks, if any). (b) Acknowledgments Regarding Obligation to Renew. Borrower acknowledges that (i) neither Administrative Agent nor any Bank has made any representations to Borrower regarding its intent to agree to any extensions set forth in this Section, (ii) neither Administrative Agent nor any Bank shall have any obligation to extend the Commitments (or any portion thereof), and (iii) Administrative Agent's and Banks' agreement to one or more extensions shall not commit Administrative Agent or the Banks to any additional extensions. (c) Payment to Rejecting Banks. If, after giving effect to any transfer of a Rejecting Bank's Commitments to an Accepting Bank or a Purchasing Bank under Section 2.10(a)(ii) above, there are any amounts owed by Borrower to such Rejecting Bank under the Loan Papers, then such amount is due and payable by Borrower to such Rejecting Bank on the Maturity Date prior to giving effect to the approved extension under Section 2.10(a)(i) above. SECTION 2.11 Increased Costs; Increased Capital. (a) If due to either (i) the introduction of or any change after the date hereof (other than any change by way of imposition or increase of reserve requirements, in the case of Adjusted CD Rate Advances, included in the Domestic Reserve Percentage or, in the case of Eurodollar Rate Advances, included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request received from any central bank or other governmental authority after the date hereof (whether or not having the force of law), there shall be any increase in the cost to any Bank of agreeing to make or making, funding, or maintaining Adjusted CD Rate Advances or Eurodollar Rate Advances, then the Borrower shall from time to time, 17 upon demand by such Bank (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost. Increased costs shall not include income, stamp, or other taxes, imposts, duties, charges, fees, deductions, or withholdings imposed, levied, collected, withheld, or assessed by the United States of America or any political subdivision or taxing authority thereof or therein (including Puerto Rico) or of the country in which any Bank's principal office or Applicable Lending office may be located or any political subdivision or taxing authority thereof or therein. Each Bank agrees that, upon the occurrence of any event giving rise to a demand under this Section 2.11(a) with respect to the Eurodollar Lending Office or the CD Lending Office of such Bank, it will, if requested by the Borrower and to the extent permitted by law or the relevant governmental authority, endeavor in good faith and consistent with its internal policies to avoid or minimize the increase in costs resulting from such event by endeavoring to change its Eurodollar Lending Office or CD Lending Office, as appropriate; provided, however, that such avoidance or minimization can be made in such a manner that such Bank, in its sole determination, suffers no economic, legal, or regulatory disadvantage. A certificate as to the amount of and specifying in reasonable detail the basis for such increased cost, submitted to the Borrower and the Administrative Agent by such Bank, shall constitute such demand and shall, in the absence of manifest error, be conclusive and binding for all purposes. (b) If either (i) the introduction after the date hereof of, or any change after the date hereof in or in the interpretation of, any law or regulation or (ii) the compliance by any Bank with any guideline or request received from any central bank or other governmental authority after the date hereof (whether or not having the force of law), affects or would affect the amount of capital required or expected to be maintained by such Bank or any corporation controlling such Bank and such Bank determines that the amount of such capital is increased by or based upon the existence of its Advances or Commitment, then the Borrower shall, from time to time, upon demand by such Bank (with a copy of such demand to the Administrative Agent), immediately pay to the Administrative Agent for the account of such Bank additional amounts sufficient to compensate such Bank to the extent that such Bank determined such increase in capital to be allocable to the existence of such Bank's Advances or Commitment. A certificate as to the amount of such increased capital and specifying in reasonable detail the basis therefor, submitted to the Borrower and the Administrative Agent by such Bank, shall constitute such demand and shall, in the absence of manifest error, be conclusive and binding for all purposes. Each Bank shall use all reasonable efforts to mitigate the effect upon the Borrower of any such increased capital requirement and shall assess any cost related to such increased capital on a nondiscriminatory basis among the Borrower and other borrowers of such Bank to which it applies and such Bank shall not be entitled to demand or be compensated for any increased capital requirement unless it is, as a result of such law, regulation, guideline, or request, such Bank's policy generally to seek to exercise such rights, where available, against other borrowers of such Bank. (c) Notwithstanding the foregoing provisions of this Section 2.11, (i) the Borrower shall not be required to reimburse any Bank for any increased costs incurred more than three months prior to the date that such Bank notifies the Borrower in writing thereof and (ii) in the event any Bank grants a participation in an Advance pursuant to Section 8.07, the Borrower shall not be obligated to reimburse for increased costs with respect to such Advance to the extent that the aggregate amount thereof exceeds the aggregate amount for which the Borrower would have been obligated if such Bank had not made such participation. SECTION 2.12 Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to the Administrative Agent for the account of each Bank any costs which such Bank determines are attributable to such Bank'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 Administrative Agent for the account of such Bank in the form of additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Bank, 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 applicable period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Bank for such period, payable on each date on which interest is payable on such Advance. Such additional interest shall be determined by such Bank and notified to the Borrower and the Administrative Agent. A certificate setting forth the amount of such additional interest, submitted to the Borrower and the Administrative Agent by such Bank, shall be conclusive and binding for all purposes, absent manifest error. 18 SECTION 2.13 Change in Legality. If any Bank shall, at least three Business Days before the date of any requested Borrowing consisting of Eurodollar Rate Advances or at least two Business Days before the date of any requested Borrowing consisting of Adjusted CD Rate Advances, notify the Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other governmental authority asserts that it is unlawful, for such Bank or its Applicable Lending Office to perform its obligations hereunder to make, fund, or maintain Eurodollar Rate Advances or Adjusted CD Rate Advances hereunder, the right of the Borrower to select Advances of such Type from such Bank for such Borrowing or any subsequent Borrowing shall be suspended until such Bank shall notify the Administrative Agent that the circumstances causing such suspension no longer exist; and during the period when such obligation of such Bank is suspended, any Borrowing consisting of Eurodollar Rate Advances or Adjusted CD Rate Advances, as the case may be, shall not exceed the Commitments of the other Banks less the aggregate amount of any Competitive Advances then outstanding, and shall be made by the other Banks pro rata according to their respective Commitments. SECTION 2.14 Payments and Computations. (a) The Borrower shall make each payment hereunder from a bank account of the Borrower located in the United States not later than 11:00 a.m. (New York City time) on the day when due in U.S. dollars to the Administrative Agent at its address referred to in Section 8.02 in same-day funds. The Administrative Agent will promptly thereafter cause to be distributed like funds to the Banks entitled thereto for the account of their respective Applicable Lending Offices, in each case to be applied in accordance with the terms of this Agreement. (b) All computations of interest based on the Alternate Base Rate shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, when determined by reference to the Prime Rate and on the basis of a year of 360 days at all other times; and all computations of fees and of interest based on the Adjusted CD Rate, the Eurodollar Rate, or the Fixed Rate shall be made by the Administrative Agent 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 Administrative Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error. (c) 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 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 next preceding Business Day. (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Administrative Agent, at the Federal Funds Effective Rate. (e) Each Bank shall maintain on its books a loan account in the name of the Borrower in which shall be recorded all Advances made by such Bank to the Borrower, the interest rate, and the maturity date of each such Advance and all payments of principal and interest made by the Borrower with respect to such Advances. The obligation of the Borrower to repay the Advances made by each Bank and to pay interest thereon shall be evidenced by the entries from time to time made in the loan account of such Bank maintained pursuant to this Section 2.14(e); provided that, the failure to make an entry with respect to an Advance shall not affect the obligations of the Borrower hereunder with respect to such Advance. In case of any dispute, action, or proceeding relating to any Advance, the 19 entries in such loan account shall be prima facie evidence of the amount of such Advance and of any amounts paid or payable with respect thereto. (f) The Administrative Agent shall maintain on its books a set of accounts in which shall be recorded all Advances made by the Banks to the Borrower, the interest rates, and maturity dates of such Advances and all payments of principal and interest made thereon. In case of any discrepancy between the entries in the Administrative Agent's books and the entries in any Bank's books, such Bank's records shall be considered correct, in the absence of manifest error. SECTION 2.15 Taxes on Payments. (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without reduction for or on account of, any income, stamp, or other taxes, imposts, duties, charges, fees, deductions, or withholdings, imposed, levied, collected, withheld, or assessed by the United States of America (or by any political subdivision or taxing authority thereof or therein) as a result of (i) the introduction after the date hereof of any law, regulation, treaty, directive, or guideline (whether or not having the force of law), or (ii) any change after the date hereof in any law, regulation, treaty, directive, or guideline (whether or not having the force of law), or (iii) any change after the date hereof in the interpretation or application of any law, regulation, treaty, directive, or guideline (whether or not having the force of law), or (iv) any such taxes, imposts, duties, charges, fees, deductions, or withholdings being imposed, levied, collected, withheld, or assessed at a greater rate than the rate that would have been applicable had such an introduction or change not been made, but only to the extent of the increase in such rate ("Withholding Taxes"). If any Withholding Taxes are required to be withheld from any amounts payable to or for the account of any Bank hereunder, the amounts so payable to or for the account of such Bank shall be increased to the extent necessary to yield to such Bank (after payment of all Withholding Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts payable to or for the account of such Bank under this Agreement prior to such introduction or change. Whenever any Withholding Tax is payable by the Borrower, as promptly as possible thereafter, the Borrower shall send to the Administrative Agent, for the account of such Bank, a certified copy of an original official receipt showing payment thereof. If the Borrower fails to pay any Withholding Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent, for the account of any Bank the required receipts or other required documentary evidence, the Borrower shall indemnify such Bank or the Administrative Agent for any incremental taxes, interest, or penalties that may become payable by such Bank or the Administrative Agent as a result of any such failure. (b) At least four Business Days prior to the first Borrowing or, if the first Borrowing does not occur within thirty days after the date of execution of this Agreement, by the end of such thirty day period, each Bank that is organized outside the United States agrees that it will deliver to the Borrower and the Administrative Agent two duly completed copies of United States Internal Revenue Service Form 1001 (or such other documentation or information as may, under applicable United States federal income tax statutes or regulations, be required in order to claim an exemption or reduction from United States income tax withholding by reason of an applicable treaty with the United States, such documentation or other information being hereafter referred to as "Form 1001") or Form 4224 (or such other documentation or information as may, under applicable United States federal income tax statutes or regulations, be required in order to claim an exemption from United States income tax withholding for income that is effectively connected with the conduct of a trade or business within the United States, such documentation or other information being hereafter referred to as "Form 4224"), as the case may. be, indicating in each case that such Bank is either entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes or, as the case may be, is subject to such limited deduction or withholding as it is capable of recovering in full from a source other than the Borrower. Each Bank which delivers to the Borrower and the Administrative Agent a Form 1001 or Form 4224 pursuant to the next preceding sentence further undertakes to deliver to the Borrower and the Administrative Agent two further copies of the said Form 1001 or 4224, or successor applicable form or certificate, as the case may be, as and when the previous form filed by it hereunder shall expire or shall become incomplete or inaccurate in any respect, unless in any of such cases an event has occurred prior to the date on which any such delivery would otherwise be required which renders such form inapplicable. 20 (c) If at any time any Bank by reason of payment by the Borrower of any Withholding Taxes obtains a credit against, or return or reduction of, any tax payable by it, or any other currently realized tax benefit, which it would not have enjoyed but for such payment ("Tax Benefit"), such Bank shall thereupon pay to the Borrower the amount which such Bank shall certify to be the amount that, after payment, will leave such Bank in the same economic position it would have been in had it received no such Tax Benefit ("Equalization Amount"); provided, however, that if such Bank shall subsequently determine that it has lost the benefit of all or a portion of such Tax Benefit, the Borrower shall promptly remit to such Bank the amount certified by such Bank to be the amount necessary to restore such Bank to the position it would have been in if no payment had been made pursuant to this Section 2.15(c); provided, further, however, that if such Bank shall be prevented by applicable law from paying the Borrower all or any portion of the Equalization Amount owing to the Borrower such payment need not be made to the extent such Bank is so prevented and the amount not paid shall be credited to the extent lawful against future payment owing to such Bank; provided, further, however, that the aggregate of all Equalization Amounts paid by any Bank shall in no event exceed the aggregate of all amounts paid by the Borrower to such Bank in respect of Withholding Taxes plus, in the case of a Tax Benefit that occurs by reason of a refund interest actually received from the relevant taxing authority with respect to such refund. A certificate submitted in good faith by the Bank pursuant to this Section 2.15(c) shall be deemed conclusive absent manifest error. (d) In the event a Bank shall become aware that the Borrower is required to pay any additional amount to it pursuant to Section 2.15(a), such Bank shall promptly notify the Administrative Agent and the Borrower of such fact and shall use reasonable efforts, consistent with legal and regulatory restrictions, to change the jurisdiction of its Applicable Lending Office if the making of such change (i) would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue, (ii) would not, in the good faith determination of such Bank, be disadvantageous for regulatory or competitive reasons to such Bank, and (iii) would not require such Bank to incur any cost or forego any economic advantage for which the Borrower shall not have agreed to reimburse and indemnify such Bank. (e) Notwithstanding the foregoing provisions of this Section 2.15, in the event any Bank grants a participation in any Advance pursuant to Section 8.07, the Borrower shall not be obligated to pay any taxes, imposts, duties, charges, fees, deductions, or withholdings to the extent that the aggregate amount thereof exceeds the aggregate amount for which the Borrower would have been obligated if such Bank had not granted such participation. SECTION 2.16 Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of setoff or otherwise) on account of the Contract Advances made by it (other than pursuant to Sections 2.11, 2.15, 2.17, 8.04, or 8.07(g) hereof) in excess of its ratable share of payments on account of the Contract Advances obtained by all the Banks, then such Bank shall forthwith purchase from the other Banks through the Administrative Agent such participations in the Contract Advances made by them as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them; provided, however, that, if all or any portion of such excess payment is thereafter recovered from such purchasing Bank, such purchase from each Bank shall be rescinded, and such Bank shall repay to the purchasing Bank the purchase price to the extent of such recovery, together with an amount equal to such Bank's ratable share (according to the proportion that the (i) the amount of such Bank's required repayment bears to (ii) the total amount so recovered from the purchasing Bank) of any interest or other amount paid or payable by the purchasing Bank in respect of the total amount so recovered. The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.16 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of setoff) with respect to such participation as fully as if such Bank were the direct creditor of the Borrower in the amount of such participation. SECTION 2.17 Removal of a Bank. The Borrower shall have the right, by giving at least 15 Business Days' prior notice in writing to the affected Bank and the Administrative Agent, at any time when no Event of Default and no event which with the passage of time or the giving of notice or both would become an Event of Default has occurred and is then continuing, to remove as a party hereto any Bank having a credit rating of C/D (or its equivalent) or lower by Thomson BankWatch, Inc. (or any successor thereto), such removal to be effective as of the date specified in such notice from the Borrower (a "Removal Date"), which date, for any Adjusted CD Rate Advance or any Eurodollar Rate Contract Advance, shall be the last day of an Interest Period and, for any Competitive Advance, shall 21 be the maturity date of such Competitive Advance. On any Removal Date, the Borrower shall repay all the outstanding Advances of the affected Bank applicable to such Removal Date, together with all accrued interest, fees, and all other amounts owing hereunder to such Bank. Upon each such Removal Date and receipt of the related payment referred to above, the Commitment relating to the Advances so paid on such Removal Date, together with all unused Commitment, of such affected Bank shall terminate, and such Bank shall cease thereafter to constitute a Bank hereunder. The Borrower shall have the right to offer to one or more Banks the right to increase their Commitments up to, in the aggregate for all such increases, the Commitment of any Bank which is removed pursuant to the foregoing provisions of this Section 2.17 (such Commitment being herein called an "Unallocated Commitment") effective on the relevant Removal Date, it being understood that no Bank shall be obligated to increase its Commitment in response to any such offer. The Borrower shall also have the right to offer all or any portion of an Unallocated Commitment to one or more Eligible Assignees not parties hereto having a credit rating higher than C/D (or its equivalent) by Thomson BankWatch, Inc. (or any successor thereto), and, upon each such bank's acceptance of such offer and execution and delivery of an instrument agreeing to the terms and conditions hereof (including, without limitation, the provisions of Section 8.07 regarding Bank assignments), each such bank shall become a Bank hereunder with a Commitment in an amount specified in such instrument. The obligations of the Borrower described in Sections 2.11, 8.04, and 8.15 shall survive for the benefit of any Bank removed pursuant to this Section 2.17 notwithstanding such removal. ARTICLE III. CONDITIONS OF LENDING SECTION 3.01 Conditions Precedent to Closing. The obligation of each Bank to make an Advance on the occasion of the initial Borrowing is subject to the conditions precedent that the Administrative Agent shall have received, on or before the Closing Date (unless otherwise indicated), the following, each dated the same day (unless otherwise indicated), in form and substance satisfactory to the Administrative Agent and in sufficient copies for each Bank: (a) Certified copies of the resolutions of the Board of Directors of the Borrower, approving this Agreement and of all documents evidencing other necessary corporate action and governmental approvals, if any, with respect to this Agreement.

(g) After applying the proceeds of each Advance, not more than 25% of the value of the assets of the Borrower and its Subsidiaries (as determined in good faith by the Borrower) that are subject to Section 5.02(a)(i) will consist of or be represented by margin stock (within the meaning of Regulation U issued by the Board of Governors of the Federal Reserve System). (h) The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U issued by the Board of Governors of the Federal Reserve System), and no proceeds of any Advance will be used for any purpose which violates the provisions of the regulations of said Board.

(k) Except as disclosed in public documents filed with the Securities and Exchange Commission or otherwise disclosed publicly on or prior to the date of the initial Borrowing, neither Borrower nor any Restricted Subsidiary is a party to a material transaction with any of its Affiliates, other than transactions in the ordinary course of business and upon fair and reasonable terms not materially less favorable than the Borrower or such Restricted 24 Subsidiary could obtain or could become entitled to in an arm's-length transaction with a Person that was not its Affiliate.

SECTION 7.02 Administrative Agent's Reliance, Etc. Neither the Administrative Agent nor any of its directors, officers, agents, or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for its or their own gross negligence or wilful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (i) may consult with legal counsel (including counsel for the Borrower), independent public accountants, and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants, or experts; (ii) makes no warranty or representation to any Bank and shall not be responsible to any Bank for any statements, warranties, or representations made in or in connection with this Agreement; (iii) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants, or conditions of this Agreement on the part of the Borrower or to inspect the property (including the books and records) of the Borrower; (iv) shall not be responsible to any Bank for the due execution, legality, validity, enforceability, genuineness, sufficiency, or value of this Agreement or any other instrument or document furnished pursuant hereto; and (v) shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate, or other instrument or writing (which may be by telecopy, telegram or cable) believed by it to be genuine and signed or sent by the proper party or parties.

With respect to its Commitment, Texas Commerce Bank National Association shall have the same rights and powers under this Agreement as any other Bank and may exercise the same as though it were not the Administrative Agent; and the term "Bank" or "Banks" shall, unless otherwise expressly indicated, include Texas Commerce Bank National Association in its individual capacity. Texas Commerce Bank National Association and its affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, the Borrower, any of its subsidiaries, and any Person 32 who may do business with or own securities of the Borrower or any such subsidiary, all as if Texas Commerce Bank National Association were not the Administrative Agent and without any duty to account therefor to the Banks. SECTION 7.04 Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Bank and based on the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement. SECTION 7.05 Indemnification. The Banks agree to indemnify each Agent, acting in their respective agency capacities, (to the extent not reimbursed by the Borrower), ratably as computed as set forth below 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 such Agent in any way relating to, or arising out of, this Agreement or any action taken or omitted by such Agent under this Agreement; provided that no Bank shall be liable to any Agent for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, or disbursements resulting from such Agent's gross negligence or wilful misconduct.

For purposes of this Section 7.05, ratable allocations among the Banks shall be made (i) in respect of any demand by the Administrative Agent prior to a declaration made pursuant to clause (ii) of Section 6.01, according to the respective amounts of their Commitments and (ii) thereafter according to the respective principal amounts of the Advances then outstanding to them. SECTION 7.06 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Banks and the Borrower and may be removed at any time with or without cause by the Majority Banks. Upon any such resignation or removal, the Majority Banks shall have the right to appoint a successor Administrative Agent with the consent of the Borrower (which consent shall not be required if at the time of such appointment any Event of Default or an event which with the passage of time or the giving of notice or both would become an Event of Default has occurred and is continuing). If no successor Administrative Agent shall have been so appointed by the Majority Banks, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent's giving of notice of resignation or the Majority Banks' removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent, which shall be a commercial bank organized or licensed under the laws of the United States of America or of any state thereof and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges, and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent's resignation or removal hereunder as Administrative Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. 33 ARTICLE VIII.

SECTION 8.03 No Waiver; Remedies.

(a) Each Bank may and, if demanded by the Borrower pursuant to subsection (g) hereof, shall assign to one or more banks or other entities all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment and the Advances owing to it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all of the rights and obligations of the Banks under this Agreement, (ii) the amount of the Commitment of the assigning Bank being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $10,000,000 and shall be an integral multiple of $1,000,000, (iii) each such assignment shall be to an Eligible Assignee, and (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register (as defined in Section 8.07(c)), an Assignment and Acceptance, together with a processing fee of $2,500. Upon such execution, delivery, acceptance, and recording, from and after the effective date specified in each Assignment and Acceptance, which effective date shall be at least three Business Days after the execution thereof, (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 Assignment and Acceptance, have the 35 rights and obligations of a Bank hereunder, and (y) the Bank assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Bank's rights and obligations under this Agreement, such Bank shall cease to be a party hereto). Notwithstanding the foregoing (unless such assignment is being made on demand of the Borrower pursuant to subsection (g)), any Bank assigning its rights and obligations under this Agreement may retain any Competitive Advances made by it outstanding at such time, and in such case shall retain its rights hereunder in respect of any Advances so retained until such Advances have been repaid in full in accordance with this Agreement. (b) By executing and delivering an Assignment and Acceptance, the Bank 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 Assignment and Acceptance, such assigning Bank makes no representation or warranty and assumes no responsibility with respect to any statements, warranties, or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency, or value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such assigning Bank 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 this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the financial statements referred to in Section 4.01(e) and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such assigning Bank or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee confirms that it is an Eligible Assignee, except for any required consent of the Borrower and Administrative Agent; (vi) such assignee appoints and authorizes the Administrative Agent to take such action as administrative agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, 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 this Agreement are required to be performed by it as a Bank. (c) The Administrative Agent shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Banks and the Commitment of, and principal amount of the Advances owing to, each Bank 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 Administrative Agent, and the Banks may treat each Person whose name is recorded in the Register as a Bank hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Bank at any reasonable time and from time to time upon reasonable prior notice. (d) Upon its receipt of an Assignment and Acceptance executed by an assigning Bank and an assignee that it is an Eligible Assignee, the Administrative Agent shall, if such Assignment and Acceptance has been completed and is in substantially the form of Exhibit B hereto, and if the processing fees required by Section 8.07 have been paid to Administrative Agent, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, (iii) give prompt notice thereof to the Borrower, and (iv) send a copy thereof to the Borrower. (e) Each Bank may sell participations to one or more banks or other entities in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment and the Advances owing to it); provided, however, that (i) such Bank's obligations under this Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrower, the Administrative Agent, and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement; and provided further, however, that such Bank shall not agree with any such bank or other financial institution to permit such bank or other financial institution to enforce the obligations of the Borrower relating to the Advances or to approve of any amendment, modification, 36 or waiver of any provision of this Agreement (other than amendments, modifications, or waivers with respect to any decrease in any fees payable hereunder or the amount of principal or rate of interest which is payable in respect of such Advances or any extension of the dates fixed for the payment thereof). (f) Any Bank may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.07, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower furnished to such Bank by or on behalf of the Borrower; provided that, prior to any such disclosure, the assignee or participant or proposed assignee or participant, if not an Eligible Assignee, shall agree to preserve the confidentiality of any confidential information relating to the Borrower received by it from such Bank. (g) If any Bank shall make demand for payment under or shall notify the Borrower that it is affected by an event described in Section 2.11 or 2.15 hereunder or shall notify the Administrative Agent pursuant to Section 2.13 hereunder, then within 15 days after such demand or such notice, the Borrower may (i) demand that such Bank assign in accordance with this Section 8.07 to one or more Eligible Assignees designated by the Borrower all (but not less than all) of such Bank's Commitment and the Advances owing to it within the next succeeding 30 days; provided that, if any such Eligible Assignee designated by the Borrower shall fail to consummate such assignment on terms acceptable to such Bank, or if the Borrower shall fail to designate any such Eligible Assignees for all or part of such Bank's Commitment or Advances, then such Bank may assign such Commitment or Advances to any other Eligible Assignee in accordance with this Section 8.07 during such 30-day period or (ii) terminate all (but not less than all) of such Bank's Commitment and repay all (but not less than all) of such Bank's Advances not so assigned on or before such 30th day in accordance with Sections 2.06 and 2.07(c) hereof (but without the requirements stated therein for ratable treatment of the Banks). Nothing in this Section 8.07(g) shall relieve the Borrower of its obligations for payment under Section 2.11 or 2.15 arising prior to an assignment or termination pursuant hereto. (h) Any Bank may at any time assign all or any portion of its rights under this Agreement to a Federal Reserve Bank; provided that no such assignment shall release a Bank from any of its obligations hereunder. In connection with any such assignment or proposed assignment, the Borrower will, promptly upon the request of any Bank, execute and deliver to such Bank a note evidencing the Borrower's obligations hereunder, in a form mutually satisfactory to the Borrower and such Bank. (i) This Section 8.07 sets forth the exclusive manner by which a Bank may assign its rights and obligations hereunder or sell participations in or to its rights and obligations hereunder. (j) Each Bank agrees to notify the Borrower of any assignment of or grant of a participating interest in any Advance, and of the identity of the assignee or participant. (k) The Borrower may not assign or delegate any rights or obligations hereunder without the prior written consent of each Bank. SECTION 8.08 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York. SECTION 8.09 Exceptions to Covenants. The Borrower may not take or fail to take any action that is permitted as an exception to any of the covenants contained in any Loan Paper if that action or omission would result in the breach of any other covenant contained in any Loan Paper. SECTION 8.10 Survival. All covenants, agreements, undertakings, representations, and warranties made in any of the Loan Papers survive all closings under the Loan Papers until payment in full of the Obligation and termination of this Agreement, except that Sections 2.11, 2.12, 2.15, 7.05, 8.04, and 8.15 (together with any other provisions in the Loan Papers which expressly provides that it shall survive termination of this Agreement) shall survive termination of this Agreement; and such covenants, agreements, undertakings, representations, and warranties, except as otherwise indicated, are not affected by any investigation made by any party. 37 SECTION 8.11 Invalid Provisions. Any provision in any Loan Paper held to be illegal, invalid, or unenforceable is fully severable; the appropriate Loan Paper shall be construed and enforced as if that provision had never been included; and the remaining provisions shall remain in full force and effect and shall not be affected by the severed provision. Administrative Agent, Banks, and the Borrower party to the affected Loan Paper agree to negotiate, in good faith, the terms of a replacement provision as similar to the severed provision as may be possible and be legal, valid, and enforceable. SECTION 8.12 Maximum Rate. Regardless of any provision contained in any Loan Paper, no Bank shall ever be entitled to contract for, charge, take, reserve, receive, or apply, as interest on the Obligation, or any part thereof, any amount in excess of the Maximum Rate, and, if Banks ever do so, then any excess shall be deemed a partial prepayment of principal and treated hereunder as such and any remaining excess shall be refunded to the Borrower. In determining if the interest paid or payable exceeds the Maximum Rate, the Borrower and Banks shall, to the maximum extent permitted under applicable law, (a) treat all Borrowings as but a single extension of credit (and Lenders and Borrower agree that such is the case and that provision herein for multiple Borrowings is for convenience only), (b) characterize any nonprincipal payment as an expense, fee, or premium rather than as interest, (c) exclude voluntary prepayments and the effects thereof, and (d) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the Obligation; provided that if the Obligation is paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for its actual period of existence thereof exceeds the Maximum Amount, Banks shall refund any excess (and Banks shall not, to the extent permitted by law, be subject to any penalties provided by any laws for contracting for, charging, taking, reserving, or receiving interest in excess of the Maximum Amount). SECTION 8.13 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. SECTION 8.14 Not in Control. Nothing in any Loan Paper gives or may be deemed to give to Administrative Agent or any Bank the right to exercise control over the Borrower or any Subsidiary's Principal Property, other assets, affairs, or management or to preclude or interfere with the Borrower or any Subsidiary's compliance with any law or require any act or omission by the Borrower or any Subsidiary that may be harmful to Persons or property. Any materiality or substantiality qualifier of any representation, warranty, covenant, agreement, or other provision of any Loan Paper is included for credit documentation purposes only and does not imply, and shall not be deemed to mean, that Administrative Agent or any Bank acquiesces in any non-compliance by the Borrower or any Subsidiary with any law, document, or otherwise or does not expect the Borrower or any Subsidiary to promptly, diligently, and continuously carry out all appropriate removal, remediation, compliance, closure, or other activities required or appropriate in accordance with all Environmental Laws. SECTION 8.15 INDEMNIFICATION. THE BORROWER SHALL INDEMNIFY, PROTECT, AND HOLD AGENTS, CHASE SECURITIES INC., EACH BANK, AND THEIR RESPECTIVE AFFILIATES, PARENTS, AND SUBSIDIARIES, AND EACH OF THE FOREGOING PARTIES' RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, REPRESENTATIVES, AGENTS, SUCCESSORS, ASSIGNS, AND ATTORNEYS (COLLECTIVELY, THE "INDEMNIFIED PARTIES") HARMLESS FROM AND AGAINST ANY AND ALL PRESENT AND FUTURE, KNOWN AND UNKNOWN, FIXED AND CONTINGENT, LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, CLAIMS, AND PROCEEDINGS AND ALL REASONABLE AND NECESSARY COSTS, EXPENSES (INCLUDING, WITHOUT LIMITATION, ALL REASONABLE ATTORNEYS' FEES AND LEGAL EXPENSES, AND AMOUNTS PAID IN SETTLEMENT WHETHER OR NOT SUIT IS BROUGHT), AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER (THE "INDEMNIFIED LIABILITIES") WHICH MAY AT ANY TIME BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST THE INDEMNIFIED PARTIES, IN ANY WAY RELATING TO OR ARISING OUT OF (A) ANY LOAN PAPERS OR TRANSACTION CONTEMPLATED BY ANY LOAN PAPER, OR (B) ANY INDEMNIFIED PARTY'S SOLE OR CONCURRENT ORDINARY NEGLIGENCE ARISING IN CONNECTION WITH ANY LOAN PAPER OR ANY TRANSACTION CONTEMPLATED BY ANY LOAN PAPER, TO THE EXTENT THAT ANY OF THE INDEMNIFIED LIABILITIES AS TO ANY INDEMNIFIED PARTY RESULTS, DIRECTLY OR INDIRECTLY, FROM ANY CLAIM MADE, OR ACTION, SUIT, OR PROCEEDING COMMENCED BY OR ON BEHALF OF ANY PERSON OTHER THAN BY SUCH INDEMNIFIED PARTY; (PROVIDED THAT, THE BORROWER SHALL HAVE NO OBLIGATION HEREUNDER TO ANY INDEMNIFIED PARTY WITH RESPECT TO ANY INDEMNIFIED LIABILITY ARISING FROM THE FRAUD, GROSS NEGLIGENCE, OR WILFUL MISCONDUCT OF SUCH INDEMNIFIED PARTY OR 38 ANY ASSOCIATED PERSON OF SUCH INDEMNIFIED PARTY. AS USED IN THIS PARAGRAPH, THE TERM "ASSOCIATED PERSON" MEANS, WITH RESPECT TO ANY PERSON, THE AFFILIATES, PARENTS, SUBSIDIARIES, DIRECTORS, OFFICERS, EMPLOYEES, REPRESENTATIVES, AGENTS, SUCCESSORS, ASSIGNS, AND ATTORNEYS OF SUCH PERSON, OR OF ANOTHER PERSON OF WHICH SUCH PERSON IS ALSO AN ASSOCIATED PERSON. THE PROVISIONS OF AND UNDERTAKINGS AND INDEMNIFICATION SET FORTH IN THIS SECTION SHALL SURVIVE THE SATISFACTION AND PAYMENT OF THE OBLIGATION AND TERMINATION OF THIS AGREEMENT. THE BORROWER MAY, AT ITS OWN COST AND EXPENSE, PARTICIPATE IN THE DEFENSE IN ANY PROCEEDING INVOLVING ANY INDEMNIFIED LIABILITY. IF NO EVENT OF DEFAULT EXISTS, THE BORROWER MAY ASSUME THE DEFENSE IN THAT PROCEEDING ON BEHALF OF THE APPLICABLE INDEMNIFIED PARTIES, INCLUDING THE EMPLOYMENT OF COUNSEL IF FIRST APPROVED (WHICH APPROVAL MAY NOT BE UNREASONABLY WITHHELD) BY THE APPLICABLE INDEMNIFIED PARTIES. IF THE BORROWER ASSUMES ANY DEFENSE, IT SHALL KEEP THE APPLICABLE INDEMNIFIED PARTIES FULLY ADVISED OF THE STATUS OF, AND SHALL CONSULT WITH THOSE INDEMNIFIED PARTIES BEFORE TAKING ANY MATERIAL POSITION IN RESPECT OF, THAT PROCEEDING. IF THE BORROWER CONSENTS OR IF ANY INDEMNIFIED PARTY REASONABLY DETERMINES THAT AN ACTUAL CONFLICT OF INTEREST EXISTS BETWEEN THE BORROWER AND THAT INDEMNIFIED PARTY WITH RESPECT TO THE SUBJECT MATTER OF THE PROCEEDING OR THAT THE BORROWER IS NOT DILIGENTLY PURSUING THE DEFENSE, THEN (I) THAT INDEMNIFIED PARTY MAY, AT THE BORROWER'S EXPENSE, EMPLOY COUNSEL TO REPRESENT INDEMNIFIED PARTY THAT IS SEPARATE FROM COUNSEL FOR THE BORROWER OR ANY OTHER PERSON IN THAT PROCEEDING AND (II) THE BORROWER IS NO LONGER ENTITLED TO ASSUME THE DEFENSE ON BEHALF OF THAT INDEMNIFIED PARTY. THE BORROWER MAY NOT AGREE TO THE SETTLEMENT OF ANY INDEMNIFIED LIABILITY WITHOUT THE PRIOR WRITTEN CONSENT OF THE APPLICABLE INDEMNIFIED PARTIES UNLESS THAT SETTLEMENT FULLY RELIEVES THOSE INDEMNIFIED PARTIES OF ANY LIABILITY WHATSOEVER FOR THAT INDEMNIFIED LIABILITY. SECTION 8.16 Certain Agents. Neither the Syndication Agent nor the Documentation Agent shall have any rights, powers, obligations, liabilities, responsibilities, or duties under this Agreement other than those applicable to all Banks as such. SECTION 8.17 Entirety. THE LOAN PAPERS REPRESENT THE FINAL AGREEMENT BETWEEN THE BORROWER, BANKS, AND ADMINISTRATIVE AGENT AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY SUCH PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN SUCH PARTIES. [Remainder of Page Intentionally Blank.
