(f) Each Bank (other than the Issuing Bank) and the Borrower hereby acknowledge that each Letter of Credit issued by the Issuing Bank pursuant to this Agreement is issued by the Issuing Bank on behalf of all of the Banks. Each Bank absolutely and irrevocably agrees, regardless of the existence or 11 continuance of an Event of Default or any other condition whatsoever, to reimburse the Issuing Bank in an amount equal to such Bank's Commitment Percentage of each drawing under any Letter of Credit made in accordance with paragraph (e) above and to be responsible for its Commitment Percentage of all liabilities incurred by the Issuing Bank in respect of each Letter of Credit opened or extended by the Issuing Bank for the account of the Borrower pursuant to this Agreement.

(g) The Issuing Bank, upon receipt of any draft drawn under a Letter of Credit, shall promptly examine such draft and any accompanying certificate or other document in accordance with its customary procedures for conformity to the requirements of such Letter of Credit. In the event the Issuing Bank determines to pay such draft in accordance with the foregoing, the Issuing Bank shall promptly notify the Banks and the Agent and each Bank shall, as contemplated by paragraph (f) of this Section 2.03, provide to the Agent for the account of the Issuing Bank in funds immediately available to the Issuing Bank, such Bank's Commitment Percentage of the funds necessary to pay such draft.

The Borrower further agrees with the Agent and the Banks that the Agent and the Banks shall not be responsible for, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrower, the beneficiary of any Letter of Credit or any financial institution or other party to which any Letter of Credit may be transferred or any claims or defenses whatsoever of the Borrower against the beneficiary of any Letter of Credit of any such transferee. The Agent and the Banks shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery or any message or advice, however transmitted, in connection with any Letter of Credit absent the Agent's and the Banks' gross negligence and willful misconduct. The Borrower agrees that any action taken or omitted by the Agent or any Issuing Bank under or in connection with each Letter of Credit and the related drafts and documents, absent the Agent's and the Banks' gross negligence and willful misconduct, shall be binding upon the Borrower and shall 12 not result in any liability on the part of the Agent or any Issuing Bank to the Borrower. (i) To the extent not inconsistent with paragraph (h) above, the Issuing Bank shall be entitled to rely, and shall be fully protected in relying upon, any Letter of Credit, draft, writing, resolution, notice, consent certificate, affidavit, letter, cablegram, telegram, facsimile, telex or teletype message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel, independent accountants and other experts selected by the Issuing Bank. The Issuing Bank shall be fully indemnified by the Banks (exclusive of the Issuing Bank's pro rata share of such indemnification obligation) against any and all liability and expense (including any expense for which the Issuing Bank has not been reimbursed by the Borrower as required by Section 9.04) which may be incurred by it by reason of taking or failing to take any action absent the Issuing Bank's gross negligence or willful misconduct. The Issuing Bank shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Required Banks, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Banks. (j) The Borrower shall, on the date of issuance or any extension or renewal of any Letters of Credit and at such other time or times as such charges are customarily made by the Issuing Bank, pay an upfront fee (in each case, a "Letters of Credit Fee") to the Agent in respect of each Letter of Credit so issued equal to 0.25% per annum for commercial letters of credit and 0.375% per annum during any Grade 1 Period (.625% per annum for any Grade 2 Period for the face amount of such Letters of Credit in excess of 50% of the aggregate amount of Commitment) for standby Letters of Credit of the face amount of such Letter of Credit, plus the Issuing Bank's issuance, amendment and other administrative fees and charges customarily charged to its customers similarly situated. Such Letter of Credit Fee (but not such customary issuance, amendment fee or other administrative fees and charges which shall be solely for the account of the Issuing bank) shall be for the accounts of the Banks in accordance with their respective Commitment Percentages. Such upfront fees shall be based on a 360 day year. (k) Upon the occurrence of an Event of Default, the Borrower shall pay to the Agent on demand an amount equal to the Maximum Drawing Amount on all Letters of Credit, which amount shall be held in an interest bearing account by the Agent for the benefit of all the Banks and the Agent as cash collateral for all obligations related to such Letters of Credit. 13 SECTION 2.04.

Unless the Agent determines that any applicable condition specified in Article III has not been satisfied, the Agent will make the funds so received from the Banks available to the Borrower at an account to be designated by Borrower. (c) Unless the Agent shall have received notice from a Bank prior to the date of any Borrowing that such Bank will not make available to the Agent such Bank's share of such Borrowing, the Agent may assume that such Bank has made such share available to the Agent on the date of such Borrowing in accordance with subsections (b) and (c) of this Section 2.04 and the 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 share available to the Agent, such Bank 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 date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the interest rate applicable thereto pursuant to Section 2.07 and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Bank's Loan included in such Borrowing for purposes of this Agreement. In no event shall any payment by the Agent, or repayment by the Borrower, of any amount pursuant to this subsection (d) relieve the Bank that failed to make available its share of the related Borrowing of its obligations hereunder. SECTION 2.05. NOTES. (a) The Loans of each Bank shall be evidenced by a single Note payable to the order of such Bank for the account of its Applicable Lending Office in an amount equal to the aggregate unpaid principal amount of such Bank's Loans. 14 (b) Upon receipt of each Bank's Note pursuant to Section 3.01(vi), the Agent shall mail such Note to such Bank. Each Bank shall record the date, amount and maturity of each Loan made by it and the date and amount of each payment of principal made by the Borrower with respect thereto, and prior to any transfer of its Note shall endorse on the schedule forming a part thereof appropriate notations to evidence the foregoing information with respect to each such Loan then outstanding; provided that the failure of any Bank to make any such recordation or endorsement shall not affect the obligations of the Borrower hereunder or under the Notes. Each Bank is hereby irrevocably authorized by the Borrower so to endorse its Note and to attach to and make a part of its Note a continuation of any such schedule as and when required. SECTION 2.06. MATURITY OF LOANS. Each Loan included in any Borrowing shall mature, and the principal amount thereof shall be due and payable, on the last day of the Interest Period applicable to such Borrowing. SECTION 2.07. INTEREST RATES. (a) Each Base Rate Loan shall bear interest on the outstanding principal amount thereof, for each day from the date such Loan is made until it becomes due, at a rate per annum equal to the Base Rate for such day. Such interest shall be payable for each Interest Period on the last day thereof. Any overdue principal of and, to the extent permitted by law, overdue interest on any Reference Rate Loan shall bear interest, payable on demand, for each day until paid at a rate (the "Default Rate") per annum equal to 2% above the Reference Rate. (b) Each CD Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the sum of the CD Margin (as in effect on the first day of such- Interest Period) plus the applicable Adjusted CD Rate. Such interest shall be payable for each Interest Period on the last day thereof and if such Interest Period is longer than 90 days, at intervals of 90 days after the first day thereof. Any overdue principal of and, to the extent permitted by law, overdue interest on any CD Loan shall bear interest, payable on demand, for each day until paid at a rate per annum equal to the Default Rate. "CD MARGIN" means 0.5% per annum during any Grade 1 Period and 0.75% per annum during any Grade 2 Period, provided, however, that such increased rate is applicable only on the incremental borrowings. 15 The "ADJUSTED CD RATE" means for any Interest Period for any CD Loan, an interest rate per annum equal at all times during such Interest Period to the sum of: (1) the rate per annum obtained by dividing (x) the rate of interest determined by the Reference Bank to be the average (rounded upward, if necessary, to the nearest whole multiple of 1/16 of 1% per annum) of the bid rates per annum quoted to the Reference Bank in the secondary market at approximately 10:00 A.M. (Chicago, Illinois time), or as soon thereafter as practicable, on the first day of such Interest Period, by two Chicago certificate of deposit dealers of recognized standing selected by the Reference Bank for the purchase at face value of certificates of deposit issued by the Reference Bank in an amount approximately equal or comparable to such Loan and with a maturity approximately equal to such Interest Period, by (y) a percentage equal to 100% minus the Domestic Reserve Percentage (as defined below) for such Interest Period, plus (2) the CD Assessment Rate (as defined below) for such Interest Period. The "CD BASE RATE" applicable to any Interest Period is the rate of interest determined by the Agent to be the average (rounded upward, if necessary, to the next higher 1/100 of one percent (1%)) of the prevailing rates per annum bid at 10:00 A.M. (Chicago time) (or as soon thereafter as practicable) on the first day of such Interest Period by two or more Chicago certificate of deposit dealers of recognized standing for the purchase at face value from the Reference Bank of its certificates of deposit in an amount comparable to the unpaid principal amount of the CD Loan of the Reference Bank to which such Interest Period applies and having a maturity comparable to such Interest Period. "DOMESTIC RESERVE PERCENTAGE" means for any day that percentage (expressed as a decimal) which is in effect on such day, as prescribed by the Board of Governors of the Federal Reserve System (or any successor) for determining the maximum reserve requirement (including without limitation any basic, supplemental or emergency reserves) for a member bank of the Federal Reserve System in Chicago, Illinois with deposits exceeding five billion dollars in respect of new non-personal time deposits in dollars in Chicago, Illinois having a maturity comparable to the related Interest Period and in an amount of $100,000 or more. The Adjusted CD Rate shall be adjusted automatically on and as of the effective date of any change in the Domestic Reserve Percentage. 16 "CD ASSESSMENT RATE" means for any Interest Period the net annual assessment rate (rounded upwards, if necessary, to the next higher 1/100 of one percent (1%)) actually incurred by Continental Bank N.A. to the Federal Deposit Insurance Corporation (or any successor) for such Corporation's (or such successor's) insuring time deposits at offices of Continental Bank N.A. in the United States during the most recent period for which such rate has been determined prior to the commencement of such Interest Period. (c) Each Euro-Dollar Loan shall bear interest on the outstanding principal amount thereof, for the Interest Period applicable thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin (as in effect on the first day of such Interest Period) plus the applicable Interbank Offered Rate. Such interest shall be payable for each Interest Period on the last day thereof and, if such Interest Period is longer than three (3) months, at intervals of three (3) months after the first day thereof. "EURO-DOLLAR MARGIN" means 0.375% per annum during any Grade 1 Period and 0.625% per annum during any Grade 2 Period, provided however, that such increased rate is applicable only on the incremental borrowings. The "INTERBANK OFFERED RATE" applicable to any Interest Period means the average (rounded upward, if necessary, to the next higher 1/16 of one percent (1%)) of the respective rates per annum at which deposits in dollars are offered by prime banks to the Reference Bank in the interbank Eurodollar market at approximately 10:00 A.M. (Chicago time) two Euro- Dollar Business Days before the first day of such Interest Period in an amount approximately equal to the principal amount of the Euro-Dollar Loan of the Reference Bank to which such Interest Period is to apply and for a period of time comparable to such Interest Period. (d) Any overdue principal of and, to the extent permitted by law, overdue interest on any Euro-Dollar Loan shall bear interest, payable on demand, for each day from and including the date payment thereof was due to but excluding the date of actual payment, at a rate per annum equal to the sum of one percent (1%) plus the average (rounded upward, if necessary, to the next higher 1/16 of one percent (1%)) of the respective rates per annum at which one day (or, if such amount due remains unpaid more than three (3) Euro-Dollar Business Days, then for such other period of time not longer than three (3) months as the Agent may select) deposits in dollars in an amount approximately equal to such overdue payment due to the Reference Bank are offered to the Reference Bank in the interbank Eurodollar market for the applicable period determined as provided above (or, if the circumstances described in clause (a) or (b) of Section 8.01 shall exist, at a rate per annum equal to the sum of one percent (1%) plus the rate applicable to Base Rate Loans for such day). 17 (e) The Agent shall determine each interest rate applicable to the Loans hereunder. The Agent shall give prompt notice to the Borrower and the participating Banks by fax or cable of each rate of interest so determined, and its determination thereof shall be conclusive in the absence of manifest error. SECTION 2.08. FEES. (a) Commitment Fee. The Borrower shall pay to the Agent for the account of the Banks ratably in proportion to their Commitments a commitment fee at the rate of 0.15% per annum on the daily average amount by which the aggregate amount of the Commitments exceeds the aggregate outstanding principal amount of the Loans. Such commitment fee shall accrue for the account of each Bank and including the Effective Date to but excluding the Termination Date of such Bank. (b) Participation Fee. Upon the execution and delivery hereof, the Borrower shall pay to the Agent for the account of each Bank a one time participation fee at the rate of 0.06% of such Bank's commitment. (c) Payments. Accrued fees under this Section for the account of any Bank shall be payable quarterly in arrears on each September 30, December 31, March 31 and June 30 and upon the date of termination of such Bank's Commitments in their entirety (and, if later, the date the Loans of such Bank shall be repaid in their entirety). SECTION 2.09. OPTIONAL TERMINATION OR REDUCTION OF COMMITMENTS. The Borrower may, upon at least three Domestic Business Day's notice to the Agent, (i) terminate the Commitments at any time, if no Loans are outstanding at such time or (ii) ratably reduce from time to time by an aggregate amount of $10,000,000 or any larger multiple of $1,000,000, the aggregate amount of the Commitments in excess of the aggregate outstanding principal amount of the Loans. 18 SECTION 2.10. MANDATORY TERMINATION OF COMMITMENTS. (a) The Commitment of each Bank shall terminate on the Termination Date of such Bank, and any Loans of such Bank then outstanding (together with accrued interest thereon) shall be due and payable on such date. SECTION 2.11. OPTIONAL PREPAYMENTS. (a) The Borrower may, upon at least one Domestic Business Day's notice to the Agent, prepay any Reference Rate Borrowing or, upon at least two Domestic Business Days notice to the Agent, prepay any CD Borrowing or, upon at least three (3) Euro-Dollar Business Days' notice to the Agent, prepay any Euro-Dollar Borrowing in whole at any time, or from time to time in part in amounts aggregating $5,000,000 or any larger multiple of $1,000,000, by paying the principal amount to be prepaid together with accrued interest thereon to but excluding the date of prepayment. Each such optional prepayment shall be applied to prepay ratably the Loans of the several Banks included in such Borrowing. (b) Upon receipt of a notice of prepayment pursuant to this Section, the Agent shall promptly notify each Bank of the contents thereof and of such Bank's ratable share (if any) of such prepayment and such notice shall not thereafter be revocable by the Borrower. SECTION 2.12. GENERAL PROVISIONS AS TO PAYMENTS. (a) The Borrower shall make each payment of principal of, and interest on, the Loans and of fees hereunder, not later than 12:00 Noon (Chicago time) on the date when due, in Federal or other funds immediately available in Chicago, to the Agent at its address referred to in Section 9.01. The Agent will promptly distribute to each Bank its ratable share, if any, of each such payment received by the Agent for the account of the Banks. Whenever any payment of principal of, or interest on, the Domestic Loans or of fees shall be due on a day which is not a Domestic Business Day, the date for payment thereof shall be extended to the next succeeding Domestic Business Day. Whenever any payment of principal of, or interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time. 19 (b) Unless the 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 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 Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that the Borrower shall not have so made such payment, each Bank shall repay to the 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 Agent, at the Federal Funds Rate. SECTION 2.13. COMPUTATION OF INTEREST AND FEES. All interest and fees shall be computed on the basis of a year of three hundred sixty (360) days and paid for the actual number of days elapsed (including the first day but excluding the last day). SECTION 2.14. MAXIMUM INTEREST RATE. (a) It is the intention of the parties hereto to comply strictly with all applicable usury laws regarding the contracting for, and the charging, payment and receipt of, interest (which shall, for purposes of this Section 2.15, be deemed to include, without limitation, any compensation received by any Bank for the use, forbearance or detention (as such terms are used in Tex. Rev. Civ. Stat. Ann. Art. 5069-1.01(a)) of the indebtedness incurred under this Agreement and evidenced by the Notes) whether such laws are now or hereafter in effect, including the laws of the United States of America or any other jurisdiction whose laws are applicable, and including any subsequent revisions to or judicial interpretations of those laws, in each case to the extent they are applicable to this Agreement and the Notes (the "Applicable Usury Laws"). (b) If any payment by the Borrower to any Bank hereunder (including any payment upon acceleration of the maturity of any Notes of such Bank) results or would result in the Borrower paying to any Bank any interest in excess of the Maximum Amount, as defined in subsection (e) below, or if any transaction contemplated by or any provision of this Agreement, such Bank's Note or Notes or any other agreement or instrument (collectively, such Bank's "Loan Documents") would otherwise be usurious under any Applicable Usury Laws, then, notwithstanding anything to the contrary in such Bank's Loan Documents, the Borrower and such Bank agree as follows: 20 (i) the provisions of this Section 2.14 shall govern and control; (ii) the aggregate amount of all interest that is contracted for, charged or received pursuant to such Bank's Loan Documents or otherwise shall under no circumstances exceed the Maximum Amount; (iii) neither the Borrower nor any other Person shall be obligated to pay the amount of such interest to the extent that it would exceed the Maximum Amount; and (iv) the provisions of such Bank's Loan Documents immediately shall be deemed reformed, without the necessity of the execution of any new document or instrument, so as to comply with all Applicable Usury Laws. (c) If any payment by the Borrower under any Bank's Loan Documents (including any payment upon acceleration of the maturity of any Note) results in the Borrower actually having paid to such Bank any interest in excess of the Maximum Amount, then such excess amount shall be applied to the reduction of the principal balance of such Bank's Loans or to other amounts (other than interest) payable hereunder, and if no such principal is then outstanding, and no such other amount is then payable, such excess or part thereof remaining, shall be repaid to the Borrower. (d) All interest paid, or agreed to be paid, pursuant to any Bank's Loan Documents shall, to the fullest extent permitted by Applicable Usury Laws, be amortized, prorated, allocated and spread throughout the full term of any indebtedness incurred under or evidenced by such Bank's Loan Documents so that the rate of interest paid under such Bank's Loan Documents does not exceed the Highest Lawful Rate in effect at any particular time during the full term thereof. (e) As used herein, the term "Maximum Amount" means, with respect to any Bank, the maximum nonusurious amount of interest that may be lawfully contracted for, charged or received by such Bank in connection with the indebtedness incurred under or evidenced by such Bank's Loan Documents under all Applicable Usury Laws, and the term "Highest Lawful Rate" means, with respect to any Bank, the maximum rate of interest, if any, that may be charged the Borrower under all Applicable Usury Laws on the principal balance of the indebtedness incurred under or evidenced by such Bank's Loan Documents from time to time outstanding. (f) In the event that the rate of interest set forth in Section 2.07 on any Loan of any Bank (the "Stated Rate"), together with any fees or other amounts payable to such Bank deemed to constitute interest under Applicable Usury Laws ("Additional Interest"), exceeds the Highest Lawful Rate, then the amount of 21 interest payable to such Bank to accrue pursuant to such Bank's Loan Documents shall be limited, notwithstanding anything to the contrary in such Bank's Loan Documents, to the amount of interest that would accrue at the Highest Lawful Rate; provided that, to the fullest extent permitted by Applicable Usury Laws, any subsequent reductions in the Stated Rate shall not reduce the interest payable to such Bank to accrue pursuant to such Bank's Loan Documents below the Highest Lawful Rate until the aggregate amount of interest payable to such Bank actually accrued pursuant to such Bank's Loan Documents, together with all Additional Interest payable to such Bank, equals the amount of interest which would have accrued if the Stated Rate had at all times been in effect and such Additional Interest, if any, had been paid in full. (g) In the event that, at maturity or upon payment in full of all amounts payable under any Bank's Loan Documents, the total amount of interest paid to any Bank or payable to such Bank and accrued under the terms of or evidenced by such Bank's Loan Documents is less than the total amount of interest which would have been paid to such Bank or accrued on the indebtedness incurred under or evidenced by such Bank's Loan Documents if the Stated Rate had, at all times, been in effect and all Additional Interest had been paid in full, then the Borrower shall, to the extent permitted by Applicable Usury Laws, pay to the Agent for the account of such Bank an amount equal to the difference between (a) the lesser of (i) the amount of interest payable to such Bank which would have accrued if the Highest Lawful Rate for such Bank had at all times been in effect or (ii) the amount of interest which would have accrued on the indebtedness incurred under or evidenced by such Bank's Loan Documents if the Stated Rate had at all times been in effect and all Additional Interest had been paid in full and (b) the amount of interest actually paid to such Bank or payable to such Bank and accrued under or evidenced by such Bank's Loan Documents. SECTION 2.15. EXTENSION OF TERMINATION DATE. (a) The Termination Date of each Bank may be extended, in the manner set forth in this Section 2.15, on June 30, 1994 and on the day following such date (an "Extension Date") for a period of 364 days after the date on which such Termination Date would otherwise have occurred. If the Borrower wishes to request an extension of the Termination Date of the Banks on any Extension Date it shall give notice to that effect to the Agent not less than forty- five (45) nor more than sixty (60) days prior to such Extension Date, whereupon the Agent shall promptly notify each of the Banks of such request. (b) Each Bank which desires to extend its Termination Date as requested by the Borrower may, at its option, so elect by notice to the Borrower and the Agent 22 within fifteen (15) days after receipt of such notice. Such notice shall be irrevocable. Any Bank which does not give such notice to the Borrower and the Agent shall be deemed to have elected not to extend its Termination Date as requested, and such Bank's Commitment shall terminate in accordance with Section 2.10 on its then Termination Date. (c) The Borrower shall have the right, with the assistance of the Agent, to seek a mutually satisfactory substitute bank or banks (which may be one or more of the Banks) to purchase the Note at par and assume the Commitment of any Bank electing not to extend its Termination Date, all in accordance with Section 9.07(c). SECTION 2.16. WITHHOLDING TAX EXEMPTION. At least five (5) Domestic Business Days prior to the first date on which interest or fees are payable hereunder for the account of any Bank, each Bank that is not incorporated under the laws of the United States of America or a state thereof agrees that it will deliver to each of the Borrower and the Agent two duly completed copies of United States Internal Revenue Service Form 1001 or 4224, certifying in either case that such Bank is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes. Each Bank which so delivers a Form 1001 or 4224 further undertakes to deliver to each of the Borrower and the Agent two additional copies of such form (or a successor form) on or before the date that such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Borrower or the Agent, in each case certifying that such Bank is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Bank from duly completing and delivering any such form with respect to it and such Bank advises the Borrower and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax. If any Bank notifies the Borrower that it is not capable of receiving payments without any deduction or withholding of United States federal income tax, the Borrower shall commence making any deductions and withholding any amounts with respect to payments for the account of such Bank that are required by applicable law. 23 ARTICLE III CONDITIONS SECTION 3.01.

ARTICLE VIII CHANGE IN CIRCUMSTANCES SECTION 8.01. ILLEGALITY. If, after the Effective Date, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans and such Bank shall so notify the Agent, the Agent shall forthwith give notice thereof to the other Banks and the Borrower whereupon until such Bank notifies the Borrower and the Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Bank to make Euro-Dollar Loans shall be suspended. Before giving any notice to the Agent pursuant to this Section, such Bank shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank shall determine that it may not lawfully continue to maintain and fund any of its outstanding Euro-Dollar Loans to maturity and shall so specify in such notice, the Borrower shall immediately prepay in full the then outstanding principal amount of each such affected 39 Euro-Dollar Loan, together with accrued interest thereon. Concurrently with prepaying each such affected Euro-Dollar Loan, the Borrower shall borrow a Reference Rate Loan (or, if the Borrower so elects by at least one Domestic Business Day's notice to the Agent and such Bank the Borrower shall borrow a CD Loan), from such Bank in a principal amount equal to the principal amount of such affected Euro-Dollar Loan for an Interest Period coincident with the remaining term of the Interest Period applicable to such affected Euro-Dollar Loan of the Borrower, and such Bank shall make such a Reference Rate Loan. SECTION 8.02. INCREASED COST AND REDUCED RETURN. (a) If on or after the Effective Date, in the case of any Committed Loan or any obligation to make Committed Loans the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Parent or Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: shall impose, modify or deem applicable any reserve, special deposit, deposit insurance assessment or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding (A) with respect to any CD Loan any such requirement included in an applicable Domestic Reserve Percentage and (B) with respect to any Euro-Dollar Loan any such requirement with respect to which such Bank is entitled to compensation during the relevant Interest Period under Section 8.04) against assets of, deposits with or for the account of, or credit extended by, any Bank (or its Applicable Lending Office); and the result of any of the foregoing is to reduce the amount of any sum received or receivable by such Bank (or its Applicable Lending Office) under this Agreement or under its Notes with respect thereto, by an amount deemed by such Bank to be material, then, within fifteen (15) days after demand by such Bank (with a copy to the Agent), the Borrower shall pay to such Bank (without duplication of amounts otherwise payable hereunder) such additional amount or amounts as will compensate such Bank for such increased cost or reduction with respect to such affected sum. (b) If any Bank shall have reasonably determined that the adoption of any applicable law, rule or regulation regarding capital adequacy or any change therein, or any change in the interpretation or administration thereof by any governmental 40 authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Parent or Applicable Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or has had the effect of reducing the rate of return on capital of such Bank (or its Parent) as a consequence of such Bank's obligations hereunder to a level below that which such Bank or its Parent could have achieved but for such adoption, change or compliance (taking into consideration such Bank's policies with respect to capital adequacy) by an amount deemed by such Bank to be material, then from time to time, within fifteen (15) days after demand by such Bank (with a copy to the Agent), the Borrower shall pay to such Bank (without duplication of amounts otherwise payable hereunder) such additional amount or amounts as will compensate such Bank or its Parent for such reduction. (c) Each Bank will promptly notify the Borrower and the Agent of any event of which it has knowledge, occurring after the Effective Date, which will entitle such Bank to compensation pursuant to this Section and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank claiming compensation under this Section, setting forth the additional amount or amounts to be paid to it hereunder and setting forth in reasonable detail the basis for such compensation shall be conclusive in the absence of manifest error, and the amount set forth therein shall be payable by Borrower within five (5) days after receipt of such certificate. In determining such amount, such Bank may use any reasonable averaging and attribution methods. (d) In the event a Bank shall incur any loss or expense (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Bank to make, continue or maintain any portion of the principal amount of any Loan as, or to convert any portion of the principal amount of any Loan into, a CD Loan or Euro-Dollar Loan) as a result of (1) any conversion or repayment or prepayment of the principal amount of any CD Loan or Euro-Dollar Loan on a date other than the scheduled last day of the Interest Period applicable thereto; (2) any Loans not being made as CD Loans or Euro-Dollar Loans in accordance with any request therefor; or (3) any Loans not being continued as, or converted into, CD Loans or Euro- Dollar Loans in accordance with the notice therefor, 41 then, upon the written notice of such Bank to the Borrower, the Borrower shall, within five days of its receipt thereof, pay to such Bank such amount as will (in its reasonable determination) reimburse such Bank for such loss or expense. Such written notice (which shall include calculations in reasonable detail) shall, in the absence of manifest error, be conclusive and binding on the Borrower. (e) If a Bank shall have determined that (1) U.S. dollar certificates of deposit or U.S. dollar deposits, as the case may be, in the relevant amount and for the relevant Interest Period are not available to such Bank in its relevant market; or (2) by reason of circumstances affecting such Bank's relevant market, adequate means do not exist for ascertaining the interest rate applicable hereunder to CD Loans or Euro-Dollar Loans of such type, then, upon notice from such Bank to the Borrower, such Bank's obligations under this Agreement to make or continue any Loans as, or to convert any Loans into, CD Loans or Euro-Dollar Loans of such type shall forthwith be suspended until such Bank shall notify the Borrower that the circumstances causing such suspension no longer exist. SECTION 8.03. SUBSTITUTE LOANS. If (i) the obligation of any Bank to make Euro-Dollar Loans has been suspended pursuant to Section 8.01 or (ii) any Bank has demanded compensation under Section 8.02(a) and the Borrower shall, by at least five (5) Euro-Dollar Business Days' prior notice to such Bank through the Agent, have elected that the provisions of this Section shall apply to such Bank, then, unless and until such Bank notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer apply: (a) all Loans which would otherwise be made by such Bank as CD Loans or Euro- Dollar Loans, as the case may be, shall be made instead as Reference Rate Loans. SECTION 8.04. REGULATION D COMPENSATION. Each Bank may require the Borrower to pay, contemporaneously with each payment of interest on Euro-Dollar Borrowings, additional interest on the related Euro- Dollar Loan of such Bank at a rate per annum equal to the excess of (i) (A) the applicable London Interbank Offered Rate divided by (B) one minus the Euro- Dollar Reserve 42 Percentage over (ii) the rate specified in clause (i)(A). Any Bank electing to require payment of such additional interest shall so notify the Borrower and the Agent, at least five (5) Euro-Dollar Business Days prior to each date on which interest is payable on the Euro-Dollar Loans of the amount then due it under this Section. SECTION 8.05. SUBSTITUTION OF BANK. If (i) the obligation of any Bank to make Euro-Dollar Loans has been suspended pursuant to 8.01 or (ii) any Bank has demanded compensation under Section 8.02 or 8.04, the Borrower shall have the right, with the assistance of the Agent, to seek a mutually satisfactory substitute bank or banks (which may be one or more of the Banks) to purchase the Notes for cash without recourse to such Bank and assume the Commitment of such Bank. Any such purchase shall be at par, shall be without prejudice to the Borrower's obligations under Section 9.04 and shall release such Bank from all further obligations under this Agreement.

(b) The Borrower agrees to indemnify each Bank and the Agent and hold each Bank and the Agent harmless from and against any and all liabilities (including without limitation, environmental liabilities), losses, damages, costs and expenses of any kind (including, without limitation, the reasonable fees and disbursements of counsel for any Bank and the Agent in connection with any investigative, administrative or judicial proceeding, whether or not such Bank or the Agent shall be designated a party thereto) which may be incurred by any Bank, or by the Agent in connection with its actions as Agent hereunder, relating to or arising out of Article VI or VII of this Agreement or any actual or proposed use of proceeds of Loans hereunder; provided that neither any Bank nor the Agent shall have the right to be indemnified hereunder for its own gross negligence or willful misconduct as determined by a court of competent jurisdiction. SECTION 9.05. AMENDMENTS, ETC. Any provision of this Agreement or the Notes may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Banks (and, if the rights or duties of the Agent are affected thereby, by the Agent); provided that no such amendment, waiver or modification shall, unless signed by all the Banks, (i) increase or decrease the Commitment of any Bank or subject any Bank to any additional obligation (except for increases to the Commitment of any Bank pursuant to Section 8.05 to which such Bank has agreed in writing), (ii) reduce the principal of or rate of interest on any Loan or any fees hereunder, (iii) postpone the date fixed for any payment of principal of or interest on any Loan or any fees hereunder or for any reduction or termination of any Commitment, 45 (iv) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Notes, or the number of Banks, which shall be required for the Banks or any of them to take any action under this Section or any other provision of this Agreement or (v) amend or waive any provision of Section 3.01 or Section 9.05. SECTION 9.06. COUNTERPARTS; INTEGRATION. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument, and any of the parties hereto may execute this Agreement by signing any such counterpart. This Agreement constitutes the entire agreement and understanding among the parties hereto and supersedes any and all prior agreements and understandings, oral or written, relating to the subject matter hereof. SECTION 9.07. SUCCESSORS AND ASSIGNS. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Borrower may not assign or otherwise transfer any of its rights under this Agreement without the prior written consent of all Banks, except as set forth in Section 5.04(a). (b) Any Bank may at any time grant to one or more banks or other institutions (each a "Participant") participating interests in its Commitment or any or all of its Loans. In the event of any such grant by a Bank of a participating interest to a Participant, whether or not upon notice to the Borrower and the Agent, such Bank shall remain responsible for the performance of its obligations hereunder, and the Borrower and the Agent shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement. Any agreement pursuant to which any Bank may grant such a participating interest shall provide that such Bank shall retain the sole right and responsibility to enforce the obligations of the Borrower hereunder including, without limitation, the right to approve any amendment, modification or waiver of any provision of this Agreement; provided that such participation agreement may provide that such Bank will not agree to any modification, amendment or waiver of this Agreement described in clause (i), (ii), (iii) or (iv) of Section 9.05 without the consent of the Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.11 and 9.04 and Article VIII with respect to its participating interest; provided that all amounts payable to a Bank for the account of a Participant under Sections 2.11 46 and 9.04 and Article VIII shall be determined as if such Bank had not granted such participation to the Participant. An assignment or other transfer which is not permitted by subsection (c) below shall be given effect for purposes of this Agreement only to the extent of a participating interest granted in accordance with this subsection (b). (c) Any Bank may upon 5 days notice by the Agent and the Borrower at any time assign to one or more banks or other institutions (each an "Assignee") all, or a part of all(a minimum of $5,000,000, in multiples of $1,000,000) of its rights and obligations under this Agreement and the Notes, and such Assignee shall assume such rights and obligations, pursuant to an instrument substantially in the form of Exhibit B attached hereto, executed by such Assignee and such transferor Bank, with (and subject to) the subscribed consent of the Borrower and the Agent, which consent shall not be unreasonably withheld; provided that if an Assignee is an affiliate of such transferor Bank, no such consent shall be required. Upon execution by the transferor Bank, the Borrower, the Assignee and the Agent, and delivery of, such an instrument and payment by such Assignee to such transferor Bank of an amount equal to the purchase price agreed between such transferor Bank and such Assignee, such Assignee shall be a Bank party to this Agreement and shall have all the rights and obligations of a Bank with a Commitment as set forth in such instrument of assumption, and the transferor Bank shall be released from its obligations hereunder to the extent of such assignment, and no further consent or action by any party shall be required. Upon the consummation of any assignment pursuant to this subsection (c), the transferor Bank, the Agent and the Borrower shall make appropriate arrangements so that, if required, new Notes are issued to the Assignee. Prior to the issuance of any such new Note, the Assignee to which such Note is issued shall pay to the Agent a fee of $2,500. (d) No Assignee or other transferee of any Bank's rights shall be entitled to receive any greater payment under Section 8.02 than such Bank would have been entitled to receive with respect to the rights transferred, unless such transfer is made with the Borrower's prior written consent or by reason of the provisions of Section 8.01 or 8.02 requiring such Bank to designate a different Lending Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exit. SECTION 9.08. SURVIVAL. The obligation of the Borrower under Article VIII and Section 9.04 shall survive the repayment of the Loans and the termination of the Commitments. 47 SECTION 9.09. ACKNOWLEDGEMENT. The Borrower acknowledges that the Banks have entered into this Agreement in reliance on the Borrower's assurance that the Borrower does not intend to use the proceeds of any Borrowings hereunder in a manner which would violate any applicable law or governmental rule or regulation. SECTION 9.10. HEADINGS. The Table of Contents and Article and Section headings used herein shall not affect the interpretation of any provision of this Agreement. SECTION 9.11. SHARING OF SETOFFS. Each Bank agrees that, if it shall, by exercising any right of setoff or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest due with respect to any Note held by it which is greater than the proportion received by any other Bank in respect of the aggregate amount of principal and interest due with respect to any Note held by such other Bank (other than disproportionate payments to any Bank provided for by this Agreement), the Bank receiving such proportionately greater payment shall purchase such participation in the Notes held by the other Banks, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Notes held by the Banks shall be shared by the Banks pro rata; provided that nothing in this Section shall impair the right of any Bank to exercise any right of setoff or counterclaim it may have and to apply the amount recovered thereby to the payment of indebtedness of the Borrower other than its indebtedness under the Notes. If under any applicable bankruptcy, insolvency or other similar law, any Bank receives a secured claim in lieu of a setoff to which this Section applies, such Bank shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Banks entitled under this Section to share in the benefits of any recovery on such secured claim. The Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any Bank which is a holder of a participation in a Note, whether or not acquired pursuant to the foregoing arrangements, may exercise rights of setoff or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower in the amount of such participation. 48 SECTION 9.12. COLLATERAL. Each of the Banks represents to the Agent and each of the other Banks that it in good faith is not relying upon any "margin stock" (as defined in Regulation U) as collateral in the extension or maintenance of the credit provided for in this Agreement.

THE BORROWER IRREVOCABLY WAIVES TO THE FULLEST EXTENT PERMITTED BY LAW, ALL CLAIM OF ERROR BY REASON OF ANY SUCH SERVICE IN ANY SUIT, ACTION OR PROCEEDING BROUGHT BY THE AGENT OR ANY BANK. THE BORROWER AGREES THAT SUCH SERVICE SHALL BE DEEMED IN EVERY RESPECT EFFECTIVE SERVICE OF PROCESS UPON THE BORROWER IN ANY SUCH SUIT, ACTION OR PROCEEDING AND SHALL, TO THE FULLEST EXTENT PERMITTED BY LAW, BE TAKEN AND HELD TO BE VALID AND PERSONAL SERVICE UPON AND PERSONAL DELIVERY TO THE BORROWER.
