Each A Borrowing shall be in an aggregate amount of $10,000,000 in the case of an A Borrowing comprised of Base Rate Advances and $25,000,000 in the case of an A Borrowing comprised of Eurodollar Rate Advances, or, in either case an integral multiple of $1,000,000 in excess thereof (or, in the case of an A Borrowing of Base Rate Advances, the aggregate unused Commitments, if less) and shall consist of A Advances of the same Type made on the same day by the Lenders ratably according to their respective Commitments. Within the limits of each Lender's Commitment, the Borrower may make more than one Borrowing on any Business Day and may borrow, prepay pursuant to Section 2.10, and reborrow under this Section 2.01. SECTION 2.02. Making the A Advances. (a) Each A Borrowing shall be made on notice by the Borrower to the Agent (a "Notice of A Borrowing") received by the Agent, (i) in the case of a proposed A Borrowing comprised of Base Rate Advances, not later than 10:00 A.M. (New York City time) on the Business Day of such proposed A Borrowing, and (ii) in the case of a proposed A Borrowing comprised of Eurodollar Rate Advances, not later than 12:00 noon (New York City time) on the third Business Day prior to the date of such proposed A Borrowing. Each Notice of A Borrowing shall be by telecopy, telefax or other teletransmission or by telephone (and if by telephone, confirmed promptly by telecopier, -15- 20 telefax or other teletransmission), in substantially the form of Exhibit C hereto, specifying therein the requested (w) date of such A Borrowing, (x) Type of A Advances comprising such A Borrowing, (y) aggregate amount of such A Borrowing, and (z) in the case of an A Borrowing comprised of Eurodollar Rate Advances, the initial Interest Period for each such A Advance. Each Lender shall, before 1:00 p.m. (New York City time) on the date of such A Borrowing, make available for the account of its Applicable Lending Office to the Agent at its address at Citibank, 399 Park Avenue, New York, New York 10043, Reference: Burlington Resources Inc., or at such other location designated by notice from the Agent to the Lenders pursuant to Section 8.02, in same day funds, such Lender's ratable portion of such A Borrowing.

(b) Each Notice of A Borrowing shall be irrevocable and binding on the Borrower. In the case of any A Borrowing which the related Notice of A Borrowing specified is to be comprised of Eurodollar Rate Advances, if such A Advances are not made as a result of any failure to fulfill on or before the date specified for such A Borrowing the applicable conditions set forth in Article III, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of such failure, including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the A Advance to be made by such Lender as part of such A Borrowing. (c) Unless the Agent shall have received notice from a Lender prior to the date of any A Borrowing that such Lender will not make available to the Agent such Lender's ratable portion of such A Borrowing, the Agent may assume that such Lender has made such portion available to the Agent on the date of such A Borrowing in accordance with subsection (a) of this Section 2.02 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 such Lender shall not have so made such ratable portion available to the Agent, such Lender and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together -16- 21 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 the Effective Federal Funds Rate for such day. If such Lender shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Lender's A Advance to the Borrower as part of such A Borrowing for purposes of this Agreement. (d) The failure of any Lender to make the A Advance to be made by it as part of any A Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its A Advance on the date of such A Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the A Advance to be made by such other Lender on the date of any A Borrowing. SECTION 2.03. Fees. (a) Facility Fee. The Borrower agrees to pay to each Lender (other than a Designated Bidder) a facility fee on the average daily amount of such Lender's Commitment, whether or not used or deemed used, from the date hereof in the case of each Initial Lender and from the effective date specified in the Assignment and Acceptance or Increase Agreement pursuant to which it became a Lender in the case of each other Lender, in each case until the Termination Date, payable quarterly in arrears on the last day of each March, June, September and December during the term of such Lender's Commitment and on the Termination Date, at a rate per annum equal to the Facility Fee Percentage in effect from time to time.

The Borrower agrees to pay to the Agent, for its own account, an arrangement fee in the amount and payable on the date separately agreed to in writing by the Agent and the Borrower. (d) Utilization Fee. The Borrower agrees to pay to each Lender (other than a Designated Bidder) a utilization fee on the average daily aggregate amount of the A Advances owing to such Lender and outstanding from time to time at a rate per annum equal to the Utilization Fee Percentage in effect from time to time, payable quarterly in arrears on the last day of -17- 22 each March, June, September and December, beginning September 30, 1994, and on the Termination Date; provided, however, that no utilization fee shall be payable with respect to any quarter or portion thereof for which the utilization fee would otherwise be payable by the Borrower in accordance with the foregoing provisions of this subsection (d) if the average daily aggregate amount of Advances owing to all the Lenders and outstanding from time to time during such quarter or portion is equal to or less than 50% of the average daily aggregate amount of the Commitments (used and unused) of all the Lenders during such quarter or portion. SECTION 2.04. Reduction of the Commitments. The Borrower shall have the right, upon at least three Business Days' notice to the Agent, to terminate in whole or reduce ratably in part the unused portions of the Commitments of the Lenders (being the amount by which such Commitments exceed the aggregate outstanding principal amount of all Advances), provided that each partial reduction shall be in the aggregate amount of $20,000,000 or any whole multiple of $1,000,000 in excess thereof. SECTION 2.05. Repayment of A Advances. The Borrower shall repay to each Lender on the Termination Date the aggregate principal amount of the A Advances then owing to such Lender. SECTION 2.06. Interest on A Advances. (a) Ordinary Interest. The Borrower shall pay interest on the unpaid principal amount of each A Advance owing to each Lender from the date of such A Advance until such principal amount is due (whether at stated maturity, by acceleration or otherwise), at the following rates: (i) Base Rate Advances. During such periods as such A Advance is a Base Rate Advance, a rate per annum equal at all times to the Base Rate in effect from time to time, payable quarterly in arrears on the last day of each March, June, September and December during such periods and on the date such Base Rate Advance shall be Converted or due (whether at stated maturity, by acceleration or otherwise). (ii) Eurodollar Rate Advances. During such periods as such A Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for such A Advance to the sum of the Eurodollar Rate for such Interest Period plus the Eurodollar Rate Margin in -18- 23 effect from time to time, payable on the last day of each such Interest Period and, if any such Interest Period has a duration of more than three months, on each day which occurs during such Interest Period every three months from the first day of such Interest Period and, if such A Advance is Converted into a Base Rate Advance on any date other than the last day of any Interest Period for such A Advance, on the date of such Conversion or, if later, the Business Day on which the Borrower shall have received at least one Business Day's prior notice from the Agent or the applicable Lender of the amount of unpaid interest accrued on such A Advances to the date of such Conversion. (b) Default Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance that is not paid when due (whether at stated maturity, by acceleration or otherwise) from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times (i) from such due date to the last day of the then existing Interest Period therefor, in the case of each Eurodollar Rate Advance, to 1% per annum above the interest rate per annum required to be paid on such A Advance immediately prior to the date on which such amount became due and (ii) from and after the last day of the then existing Interest Period therefor, in the case of each Eurodollar Rate Advance, and at all times in the case of each Base Rate Advance or B Advance, to 1% per annum above the Base Rate in effect from time to time. SECTION 2.07. Additional Interest on Eurodollar Rate Advances. If any Lender shall determine in good faith that reserves under regulations of the Board of Governors of the Federal Reserve System are required to be maintained by it in respect of, or a portion of its costs of maintaining reserves under such regulations is properly attributable to, one or more of its Eurodollar Rate Advances, the Borrower shall pay to such Lender additional interest on the unpaid principal amount of each such Eurodollar Rate Advance (other than any such additional interest accruing to a particular Lender in respect of periods prior to the 30th day preceding the date notice of such interest is given by such Lender as provided in this Section 2.07), payable on the same day or days on which interest is payable on such A Advance, at an interest rate per annum equal at all times during each Interest Period for such A Advance to the excess of (i) the rate obtained by dividing the Eurodollar Rate for such Interest Period by a percentage equal to 100% minus the Eurodollar Reserve Percentage, if any, for such Lender for -19- 24 such Interest Period over (ii) the Eurodollar Rate for such Interest Period. The amount of such additional interest (if any) shall be determined by each Lender, and such Lender shall furnish written notice of the amount of such additional interest to the Borrower and the Agent, which notice shall be conclusive and binding for all purposes, absent manifest error. SECTION 2.08. Interest Rate Determination. (a) Each Reference Bank agrees to furnish to the Agent timely information for the purpose of determining each Eurodollar Rate. If any one or more of the Reference Banks shall not furnish such timely information to the Agent for the purpose of determining any such interest rate, the Agent shall determine such interest rate on the basis of timely information furnished by the remaining Reference Banks. (b) The Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Agent for purposes of Section 2.06(a)(i) or (ii), and the applicable rate, if any, furnished by each Reference Bank for the purpose of determining the applicable interest rate under Section 2.06(a)(ii). (c) If fewer than two Reference Banks furnish timely information to the Agent for determining the Eurodollar Rate for any applicable A Advances, (i) the Agent shall give the Borrower and each Lender prompt notice by telephone (confirmed in writing) that the interest rate cannot be determined for such applicable A Advances, (ii) each such A Advance that is a Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance (or if such A Advance is then a Base Rate Advance, will continue as a Base Rate Advance), and (iii) the obligations of the Lenders to make, or to Convert A Advances into, Eurodollar Rate Advances, as the case may be, shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist. (d) If, with respect to any Eurodollar Rate Advances, the Majority Lenders determine and give notice to the Agent that as a result of conditions in or generally affecting the relevant market, the rates of interest determined on the -20- 25 basis of the Eurodollar Rate for any Interest Period for such A Advances will not adequately reflect the cost to such Majority Lenders of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, the Agent shall forthwith so notify the Borrower and the Lenders, whereupon, (i) each such Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to make, or to Convert A Advances into, Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist. (e) If the Borrower shall fail to select the duration of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of "Interest Period" in Section 1.01, the Agent will forthwith so notify the Borrower and the Lenders and such Eurodollar Rate Advances will automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Advances. (f) On the date on which the aggregate unpaid principal amount of A Advances comprising any A Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $10,000,000, such A Advances shall, if they are Eurodollar Rate Advances, automatically Convert into Base Rate Advances, and on and after such date the right of the Borrower to Convert such A Advances into Eurodollar Rate Advances shall terminate; provided, however, that if and so long as each such A Advance shall be, or be elected to be Converted to, Eurodollar Rate Advances having the same Interest Period as Eurodollar Rate Advances comprising another A Borrowing or other A Borrowings, and the aggregate unpaid principal amount of all such Eurodollar Rate Advances shall, or upon such Conversion will, equal or exceed $20,000,000, the Borrower shall have the right to continue all such Eurodollar Rate Advances as, or to Convert all such A Advances into, Eurodollar Rate Advances having such Interest Period. SECTION 2.09. Voluntary Conversion of A Advances. The Borrower may on any Business Day, upon notice given to the Agent, not later than 10:00 A.M. (New York City time) on the Business Day of the proposed Conversion of Eurodollar Rate -21- 26 Advances to Base Rate Advances, and not later than 12:00 noon (New York City time) on the third Business Day prior to the date of the proposed Conversion in the case of a Conversion of Base Rate Advances to Eurodollar Rate Advances, and subject to the provisions of Section 2.08, 2.11 and 2.13, Convert all A Advances of one Type comprising the same A Borrowing into A Advances of the other Type; provided, however, that any Conversion of any Eurodollar Rate Advances into Base Rate Advances made on any day other than the last day of an Interest Period for such Eurodollar Rate Advances shall be subject to the provisions of Section 8.04(b). Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the A Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the Interest Period for each such Eurodollar Rate Advance.

SECTION 2.11. Increased Costs. (a) If, due to either (i) the introduction after the date of this Agreement of or any change after the date of this Agreement (including any change by way of imposition or increase of reserve requirements or assessments other than those referred to in the definition of "Eurodollar Reserve Percentage" contained in Section 1.01) in or in the -22- 27 interpretation of any law or regulation or (ii) the compliance with any guideline or request issued or made after the date of this Agreement from or by any central bank or other governmental authority (whether or not having the force of law), in each case above other than those referred to in Section 2.12, there shall be any increase in the cost to any Lender of agreeing to make, fund or maintain, or of making, funding or maintaining, Eurodollar Rate Advances funded in the interbank Eurodollar market, then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender additional amounts sufficient to reimburse such Lender for all such increased costs (except those incurred more than 60 days prior to the date of such demand; for the purposes hereof any cost or expense allocable to a period prior to the publication or effective date of such an introduction, change, guideline or request shall be deemed to be incurred on the later of such publication or effective date). Each Lender agrees to use its best reasonable efforts promptly to notify the Borrower of any event referred to in clause (i) or (ii) above, provided that the failure to give such notice shall not affect the rights of any Lender under this Section 2.11(a) (except as otherwise expressly provided above in this Section 2.11(a)). A certificate as to the amount of such increased cost, submitted to the Borrower and the Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error. After one or more Lenders have notified the Borrower of any increased costs pursuant to this Section 2.11, the Borrower may specify by notice to the Agent and the affected Lenders that, after the date of such notice whenever the election of a Eurodollar Rate Advance by the Borrower for an Interest Period or portion thereof would give rise to such increased costs, such election shall not apply to the A Advances of such Lender or Lenders during such Interest Period or portion thereof, and, in lieu thereof, such A Advances shall during such Interest Period or portion thereof be Base Rate Advances. Each Lender agrees to use its best reasonable efforts (including, without limitation, a reasonable effort to change its Applicable Lending Office or to transfer its affected A Advances to an Affiliate of such Lender) to avoid, or minimize the amount of, any demand for payment from the Borrower under this Section 2.11. (b) In the event that any Lender shall change its Eurodollar Lending Office and such change results (at the time of such change) in increased costs to such Lender, the Borrower shall not be liable to such Lender for such increased costs incurred by such Lender to the extent, but only to the extent, that such increased costs shall exceed the increased -23- 28 costs which such Lender would have incurred if the Eurodollar Lending Office of such Lender had not been so changed, but, subject to subsection (a) of this Section 2.11 and to Section 2.13, nothing herein shall require any Lender to change its Eurodollar Lending Office for any reason. SECTION 2.12. Increased Capital. If either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) compliance by any Lender with any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and such Lender determines that the amount of such capital is increased by or based upon the existence of such Lender's commitment to lend hereunder and other commitments of this type, then, within ten days after demand, and delivery to the Borrower of the certificate referred to in the last sentence of this Section 2.12 by such Lender (with a copy of such demand to the Agent), the Borrower shall pay to the Agent for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender's commitment to lend hereunder (except any such increase in capital incurred more than, or compensation attributable to the period before, 90 days prior to the date of such demand; for the purposes hereof any increase in capital allocable to, or compensation attributable to, a period prior to the publication or effective date of such an introduction, change, guideline or request shall be deemed to be incurred on the later of such publication or effective date). Each Lender agrees to use its best reasonable efforts promptly to notify the Borrower of any event referred to in clause (i) or (ii) above, provided that the failure to give such notice shall not affect the rights of any Lender under this Section 2.12 (except as otherwise expressly provided above in this Section 2.12). A certificate in reasonable detail as to the basis for, and the amount of, such compensation submitted to the Borrower and the Agent by such Lender shall, in the absence of manifest error, be conclusive and binding for all purposes. SECTION 2.13. Illegality. Notwithstanding any other provision of this Agreement, if the introduction of or any change in or in the interpretation of any law or regulation shall make it unlawful, or any central bank or other governmental authority shall assert that it is unlawful, for -24- 29 any Lender or its Applicable Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to continue to fund or maintain such Advances hereunder, such Lender may, by notice to the Borrower and the Agent, suspend the right of the Borrower to elect Eurodollar Rate Advances from such Lender and, if necessary in the reasonable opinion of such Lender to comply with such law or regulation, Convert all such Eurodollar Rate Advances of such Lender to Base Rate Advances at the latest time permitted by the applicable law or regulation, and such suspension and, if applicable, such Conversion shall continue until such Lender notifies the Borrower and the Agent that the circumstances making it unlawful for such Lender to perform such obligations no longer exist (which such Lender shall promptly do when such circumstances no longer exist). So long as the obligation of any Lender to make Eurodollar Rate Advances has been suspended under this Section 2.13, all Notices of A Borrowing specifying A Advances of such Type shall be deemed, as to such Lender, to be requests for Base Rate Advances. Each Lender agrees to use its best reasonable efforts (including, without limitation, a reasonable effort to change its Applicable Lending Office or to transfer its affected A Advances to an affiliate) to avoid any such illegality. SECTION 2.14. Payments and Computations. (a) The Borrower shall make each payment hereunder (including, without limitation, under Section 2.03, 2.05 or 2.06) and under the Notes, whether the amount so paid is owing to any or all of the Lenders or to the Agent, not later than 1:00 P.M. (New York City time) without setoff, counterclaim, or any other deduction whatsoever, on the day when due in U.S. dollars to the Agent at Citibank, 399 Park Avenue, New York, New York, Reference: Burlington Resources Inc., or at such other location designated by notice to the Borrower from the Agent and agreed to by the Borrower, in same day funds. Each such payment made by the Borrower for the account of any Lender hereunder, when so made to the Agent, shall be deemed duly made for all purposes of this Agreement and the A Notes, except that if at any time any such payment is rescinded or must otherwise be returned by the Agent or any Lender upon the bankruptcy, insolvency or reorganization of the Borrower or otherwise, such payment shall be deemed not to have been so made. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or fees ratably (other than amounts payable pursuant to Section 2.07, 2.11, 2.12, 2.13, 2.15, 2.19 or 8.04(b)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any -25- 30 other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to Section 8.07(d), from and after the effective date specified in such Assignment and Acceptance, the Agent shall make all payments hereunder and under the A Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. (b) All computations of interest based on the Base Rate and of facility fees and utilization fees shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate, or the Effective Federal Funds Rate shall be made by the Agent, and all computations of interest pursuant to Section 2.07 shall be made by each Lender with respect to its own Eurodollar Rate Advances, on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Agent (or, in the case of Section 2.07, 2.11, 2.12, 2.13, 2.15, 2.19 or 8.04(b), by each Lender with respect to its own Advances) of an interest rate or an increased cost, loss or expense or increased capital or of illegality or taxes hereunder shall be conclusive and binding for all purposes if made reasonably and in good faith. (c) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or facility fees or utilization fees, as the case may be; provided, however, 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 Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be -26- 31 distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent the Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at a rate equal to the Effective Federal Funds Rate for such day. SECTION 2.15. Taxes. (a) Any and all payments by the Borrower hereunder or under the Notes shall be made in accordance with Section 2.14, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding in the case of each Indemnified Party, (i) all taxes, levies, imposts, deductions, charges, or withholdings, and all liabilities with respect thereto, imposed on or determined by reference to its income, and all franchise taxes, and (ii) all other taxes, levies, imposts, deductions, charges, or withholdings in effect at the time that such Indemnified Party executed this Agreement or otherwise became an "Indemnified Party" hereunder, and liabilities with respect thereto, imposed on it by reason of the jurisdiction in which such Indemnified Party is organized, domiciled, resident or doing business, or any political subdivision thereof, or by reason of the jurisdiction of its Applicable Lending Office or any other office from which it makes or maintains any extension of credit hereunder or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments under this Agreement or under the Notes being herein referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Note to any Indemnified Party, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.15) such Indemnified Party receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower (or the Agent, as applicable) shall make such deductions at the applicable statutory rate and (iii) the Borrower (or the Agent, as applicable) shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law, provided that the Borrower shall not be required to pay any additional amount (and shall be relieved -27- 32 of any liability with respect thereto) pursuant to this subsection (a) (or pursuant to Section 2.15(c), except to the extent Section 2.15(c) relates to Other Taxes) to any Indemnified Party that either (x) on the date such Indemnified Party executed this Agreement or otherwise became an "Indemnified Party" hereunder, either (A) was not entitled to submit a U.S. Internal Revenue Service form 1001 (relating to such Indemnified Party, and entitling it to a complete exemption from withholding on all amounts to be received by such Indemnified Party, including fees, pursuant to this Agreement or the Advances) or a U.S. Internal Revenue Service form 4224 (relating to all amounts to be received by such Indemnified Party, including fees, pursuant to this Agreement and the Advances) or (B) is not a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code), or (y) has failed to submit any form or certificate that it was required to file or provide pursuant to subsection (d) of this Section 2.15 and is entitled to file or give, as applicable, under applicable law, provided, further, that should an Indemnified Party become subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such administrative steps as such Indemnified Party shall reasonably request to assist such Indemnified Party to recover such Taxes, and provided further, that each Indemnified Party, with respect to itself, agrees to indemnify and hold harmless the Borrower from any taxes, penalties, interest and other expenses, costs and losses incurred or payable by the Borrower as a result of the failure of the Borrower to comply with its obligations under clauses (ii) or (iii) above in reliance on any form or certificate provided to it by such Indemnified Party pursuant to this Section 2.15. If any Indemnified Party receives a net credit or refund in respect of such Taxes or amounts so paid by the Borrower, it shall promptly notify the Borrower of such net credit or refund and shall promptly pay such net credit or refund to the Borrower, provided that the Borrower agrees to return such net credit or refund if the Indemnified Party to which such net credit or refund is applicable, is required to repay it. (b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under the Notes or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or the Notes (hereinafter referred to as "Other Taxes"). -28- 33 (c) The Borrower will indemnify each Indemnified Party for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.15) paid by such Indemnified Party and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto except as a result of the gross negligence (which shall in any event include the failure of such Indemnified Party to provide to the Borrower any form or certificate that it was required to provide pursuant to subsection (d) below) or willful misconduct of such Indemnified Party, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within 30 days from the date such Indemnified Party makes written demand therefor. (d) On or prior to the date on which each Indemnified Party organized under the laws of a jurisdiction outside the United States executes this Agreement or otherwise becomes an "Indemnified Party" hereunder, such Indemnified Party shall provide the Borrower and the Agent with U.S. Internal Revenue Service form 1001 or 4224, as appropriate, or any successor form prescribed by the U.S. Internal Revenue Service, certifying that such Indemnified Party is fully exempt from United States withholding taxes with respect to all payments to be made to such Indemnified Party hereunder, or other documents satisfactory to the Borrower indicating that all payments to be made to such Indemnified Party hereunder are fully exempt from such taxes. Thereafter and from time to time, each such Indemnified Party shall submit to the Borrower and the Agent such additional duly completed and signed copies of one or the other of such forms (or such successor forms as shall be adopted from time to time by the relevant United States taxing authorities) as may be (i) notified by the Borrower to such Indemnified Party and (ii) required under then-current United States law or regulations to avoid United States withholding taxes on payments in respect of all amounts to be received by such Indemnified Party pursuant to this Agreement or the Notes, including without limitation fees. Upon the request of the Borrower from time to time, each Indemnified Party that is a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code) shall submit to the Borrower a certificate to the effect that it is such a United States person. If any Indemnified Party determines, as a result of any change in applicable law, regulation or treaty, or in any official application or interpretation thereof, that it is unable to submit to the Borrower any form or certificate that such Indemnified Party is obligated to -29- 34 submit pursuant to this subsection (d), or that such Indemnified Party is required to withdraw or cancel any such form or certificate previously submitted, such Indemnified Party shall promptly notify the Borrower and the Agent of such fact. (e) Any Indemnified Party claiming any additional amounts payable pursuant to this Section 2.15 shall use its best reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts which may thereafter accrue and would not, in the reasonable judgment of such Indemnified Party, be otherwise disadvantageous to such Indemnified Party. (f) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower and each Indemnified Party contained in this Section 2.15 shall survive the payment in full of principal and interest hereunder and under the Notes. SECTION 2.16. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the A Advances made by it (other than pursuant to Section 2.07, 2.11, 2.12, 2.13, 2.15 or 8.04(b)) in excess of its ratable share of payments on account of the A Advances obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in the A Advances made by them as shall be necessary to cause such purchasing Lender 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 Lender, such purchase from each Lender shall be rescinded and each Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender's ratable share (according to the proportion of (i) the amount of the participation purchased from such Lender as a result of such excess payment to (ii) the total amount of such excess payment) of such recovery together with an amount equal to such Lender's ratable share (according to the proportion of (i) the amount of such Lender's required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section may, to the fullest extent permitted by law, exercise all its rights of -30- 35 payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. SECTION 2.17. Evidence of Debt. The indebtedness of the Borrower to each Lender in respect of principal of and interest on the A Advances shall be evidenced by an A Note payable to the order of such Lender and delivered hereunder by the Borrower. Notwithstanding the provisions of the A Notes for notations to be made on the grid attached thereto, any Lender may maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower resulting from A Advances and payments made from time to time hereunder and under the A Note payable to its order. In any legal action or proceeding in respect of this Agreement or such A Note, the entries made in such account or accounts shall be conclusive evidence of the existence and amounts of the obligations of the Borrower therein recorded, absent manifest error. SECTION 2.18. Use of Proceeds. Proceeds of the Advances may be used for general corporate purposes of the Borrower and its Subsidiaries, including, without limitation, for acquisitions and for payment of commercial paper issued by the Borrower. SECTION 2.19. The B Advances. (a) Each Lender severally agrees that the Borrower may make B Borrowings under this Section 2.19 from time to time on any Business Day during the period from the date hereof until the earlier of (I) the Termination Date or (II) June 15, 1999, in the manner set forth below; provided that (x) each B Borrowing shall be in an aggregate amount of $25,000,000 or an integral multiple of $5,000,000 in excess thereof and (y) following the making of each B Borrowing, the aggregate number of outstanding B Borrowings shall not exceed seven and the aggregate amount of all Advances then outstanding shall not exceed the aggregate amount of the Commitments of the Lenders (computed without regard to any B Reduction). (i) The Borrower may request a B Borrowing under this Section 2.19 by delivering to the Agent, by telecopy, telefax or other teletransmission, a notice of a B Borrowing (a "Notice of B Borrowing"), in substantially the form of Exhibit D hereto, specifying the date and aggregate amount of the proposed B Borrowing, the maturity date for repayment of each B Advance to be made as part of such B Borrowing (which maturity date may not be earlier than the date occurring -31- 36 30 days after the date of such B Borrowing or later than the earlier of (x) 180 days after the date of such B Borrowing or (y) July 15, 1999), the interest payment date or dates relating thereto, and any other terms to be applicable to such B Borrowing, not later than 10:00 A.M. (New York City time) (A) at least one Business Day prior to the date of the proposed B Borrowing, if the Borrower shall specify in the Notice of B Borrowing that the rates of interest to be offered by the Lenders shall be fixed rates per annum and (B) at least four Business Days prior to the date of the proposed B Borrowing, if the Borrower shall instead specify in the Notice of B Borrowing the basis to be used by the Lenders in determining the rates of interest to be offered by them. The Agent shall in turn promptly notify each Lender of each request for a B Borrowing received by it from the Borrower by sending such Lender a copy of the related Notice of B Borrowing. (ii) Each Lender may, if in its sole and absolute discretion it elects to do so, irrevocably offer to make one or more B Advances to the Borrower as part of such proposed B Borrowing at a rate or rates of interest specified by such Lender in its sole discretion, by notifying the Agent (which shall give prompt notice thereof to the Borrower), before 10:00 A.M. (New York City time) (x) on the date of such proposed B Borrowing in the case of a Notice of B Borrowing delivered pursuant to clause (A) of paragraph (i) above, and (y) three Business Days before the date of such proposed B Borrowing in the case of a Notice of B Borrowing delivered pursuant to clause (B) of paragraph (i) above, of the minimum amount and maximum amount of each B Advance which such Lender would be willing to make as part of such proposed B Borrowing (which amounts may, subject to clause (y) of the proviso to the first sentence of this Section 2.19(a), exceed such Lender's Commitment), the rate or rates of interest therefor and such Lender's Applicable Lending Office with respect to such B Advance; provided that if the Agent in its capacity as a Lender 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 on which notice of such election is to be given to the Agent by the other Lenders. If any Lender shall elect not to make such an offer, such Lender shall so notify the Agent, before 10:00 A.M. (New York City time) on the date on which notice of such election is to be given to the Agent by the other Lenders, and such Lender shall not be obligated to, and shall not, make any B -32- 37 Advance as part of such B Borrowing; provided that the failure by any Lender to give such notice shall not cause such Lender to be obligated to make any B Advance as part of such proposed B Borrowing. (iii) The Borrower shall, in turn, before 11:00 A.M. (New York City time) (x) on the date of such proposed B Borrowing, in the case of a Notice of B Borrowing delivered pursuant to clause (A) of paragraph (i) above and (y) three Business Days before the date of such proposed B Borrowing in the case of a Notice of B Borrowing delivered pursuant to clause (B) of paragraph (i) above, either A. cancel such B Borrowing by giving the Agent notice to that effect, or B. accept one or more of the offers made by any Lender or Lenders pursuant to paragraph (ii) above, in order of the lowest to highest rates of interest or margins (or, if two or more Lenders bid at the same rates of interest, and the amount of accepted offers is less than the aggregate amount of such offers, the amount to be borrowed from such Lenders as part of such B Borrowing shall be allocated among such Lenders pro rata on the basis of the maximum amount offered by such Lenders at such rates or margin in connection with such B Borrowing), in any aggregate amount up to the aggregate amount initially requested by the Borrower in the relevant Notice of B Borrowing, by giving notice to the Agent of the amount of each B Advance (which amount shall be equal to or greater than the minimum amount, and equal to or less than the maximum amount, notified to the Borrower by the Agent on behalf of such Lender for such B Advance pursuant to paragraph (ii) above) to be made by each Lender as part of such B Borrowing, and reject any remaining offers made by Lenders pursuant to paragraph (ii) above by giving the Agent notice to that effect. (iv) If the Borrower notifies the Agent that such B Borrowing is cancelled pursuant to paragraph (iii)(A) above, the Agent shall give prompt notice thereof to the Lenders and such B Borrowing shall not be made. (v) If the Borrower accepts one or more of the offers made by any Lender or Lenders pursuant to para- -33- 38 graph (iii)(B) above, the Agent shall in turn promptly notify (A) each Lender that has made an offer as described in paragraph (ii) above, of the date and aggregate amount of such B Borrowing and whether or not any offer or offers made by such Lender pursuant to paragraph (ii) above have been accepted by the Borrower, (B) each Lender that is to make a B Advance as part of such B Borrowing, of the amount of each B Advance to be made by such Lender as part of such B Borrowing, and (C) each Lender that is to make a B Advance as part of such B Borrowing, upon receipt, that the Agent has received forms of documents appearing to fulfill the applicable conditions set forth in Article III. Each Lender that is to make a B Advance as part of such B Borrowing shall, before 12:00 noon (New York City time) on the date of such B Borrowing specified in the notice received from the Agent pursuant to clause (A) of the preceding sentence or any later time when such Lender shall have received notice from the Agent pursuant to clause (C) of the preceding sentence, make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.02 such Lender's portion of such B Borrowing, in same day funds. Upon fulfillment of the applicable conditions set forth in Article III and after receipt by the Agent of such funds, the Agent will make such funds available to the Borrower at the Agent's aforesaid address. Promptly after each B Borrowing the Agent will notify each Lender of the amount of the B Borrowing, the consequent B Reduction and the dates upon which such B Reduction commenced and will terminate. (b) Within the limits and on the conditions set forth in this Section 2.19, the Borrower may from time to time borrow under this Section 2.19, repay or prepay pursuant to subsection (c) below, and reborrow under this Section 2.19. (c) The Borrower shall repay to the Agent for the account of each Lender which has made a B Advance, or each other holder of a B Note, on the maturity date of each B Advance (such maturity date being that specified by the Borrower for repayment in the related Notice of B Borrowing and provided in the B Note evidencing such B Advance), the then unpaid principal amount of such B Advance. The Borrower shall have no right to prepay any B Advance unless, and then only on the terms, specified by the Borrower for such B Advance in the related Notice of B Borrowing delivered pursuant to Section 2.19(a)(i) and set forth in the B Note -34- 39 evidencing such B Advance or unless the holder of such B Advance otherwise consents in writing to such prepayment. (d) The Borrower shall pay interest on the unpaid principal amount of each B Advance from the date of such B Advance to the date the principal amount of such B Advance is repaid in full at the rate of interest for such B Advance specified by the Lender making such B Advance in its notice delivered pursuant to subsection (a)(ii) above on the interest date or dates specified by the Borrower for such B Advance in the related Notice of B Borrowing and set forth in the B Note evidencing such B Advance, subject to Section 2.06(b). (e) The indebtedness of the Borrower in respect of principal of and interest on each B Advance made to the Borrower as part of a B Borrowing shall be evidenced by a separate B Note of the Borrower payable to the order of the Lender making such B Advance. (f) Each time that the Borrower gives a Notice of B Borrowing, the Borrower shall pay to the Agent for its own account such fee as may be agreed between the Borrower and the Agent from time to time, whether or not any B Borrowing is in fact made. (g) Following the making of each B Borrowing, the Borrower agrees that it will be in compliance with the limitations set forth in clause (y) of the proviso to the first sentence of Section 2.19(a). (h) The failure of any Lender to make the B Advance to be made by it as part of any B Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its B Advance on the date of such B Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the B Advance to be made by such other Lender on the date of any B Borrowing. If any Designated Bidder fails to make the B Advance to be made by it as part of any B Borrowing, such Designated Bidder shall not thereafter have the right to offer to make any B Advance without the prior written consent of the Borrower and the Agent. SECTION 2.20. Increase of Commitments. The Borrower shall have the right, without the consent of the Lenders or the Agent (except as contemplated in clauses (d) and (e) of this sentence), to effectuate from time to time, on any Business Day (but not on more than one Business Day in any calendar quarter) an increase in the total Commitments under this Agreement (an "Increase") by adding to this Agreement one -35- 40 or more banks or other financial institutions (who shall, upon completion of the requirements stated in this Section 2.20, constitute Lenders hereunder), or by allowing one or more Lenders to increase their Commitments hereunder, or both, provided that (a) no Increase in Commitments pursuant to this Section 2.20 shall result in the total Commitments exceeding $800,000,000 or shall result in the aggregate amount of the Increases in the Commitments effectuated pursuant to this Section 2.20 since the date of this Agreement exceeding $200,000,000, (b) any Increase in Commitments pursuant to this Section 2.20 shall be in the amount of $20,000,000 or an integral multiple of $1,000,000 in excess thereof, (c) on the effective date of each Increase in the Commitments pursuant to this Section 2.20, (i) the Borrower shall have outstanding public long-term senior unsecured debt securities that are rated by S&P or Moody's, (ii) either (1) the lowest such rating by Moody's shall be A3 or better or (2) the lowest such rating by S&P shall be A- or better, and (iii) no event shall have occurred and be continuing which constitutes an Event of Default or would constitute an Event of Default but for the requirement that notice be given or time elapse or both, (d) no Lender's Commitment amount shall be increased without the consent of such Lender, (e) each new bank or other financial institution, if any, both is acceptable to the Agent and provides a Commitment of at least $20,000,000, (f) simultaneously with each increase in the Commitment of any Lender pursuant to this Section 2.20, the Borrower will cause such Lender's "Commitment" (under and as defined in the Short-Term Revolving Credit Agreement) to be increased pursuant to Section 2.20 thereof by the same percentage as such Lender's Commitment is being increased pursuant to this Section 2.20, unless the Short-Term Revolving Credit Agreement has been terminated, (g) simultaneously with the addition of any bank or financial institution pursuant to this Section 2.20, the Borrower will cause such bank or financial institution to become a party to the Short-Term Revolving Credit Agreement pursuant to Section 2.20 thereof with a "Commitment" (under and as defined in the Short-Term Revolving Credit Agreement) that constitutes the same percentage of all "Commitments" thereunder as the percentage that its Commitment hereunder constitutes of all Commitments hereunder, unless the Short-Term Revolving Credit Agreement has been terminated, and (h) immediately prior to, or simultaneously with, any Increase pursuant to this Section 2.20, the Borrower will prepay in accordance with the terms of this Agreement, all outstanding A Advances, if any (including, without limitation, prepayment from the proceeds of any A Borrowing from the Lenders made on the date of such Increase in accordance with this Agreement and in accordance with their respective Commitments after -36- 41 giving effect to such Increase). The Borrower shall give the Agent ten Business Days' notice of the Borrower's intention to effect any Increase in the total Commitments pursuant to this Section 2.20. Such notice shall specify each new bank or other financial institution, if any, the changes in amounts of Commitments that will result, if any, and such other information as is reasonably requested by the Agent. Each new bank or other financial institution, and each Lender agreeing to increase its Commitment, shall execute and deliver to the Agent an Increase Agreement, substantially in the form of Exhibit F-1 hereto or Exhibit F-2 hereto, as the case may be, pursuant to which it becomes a party hereto or increases its Commitment, as the case may be. In addition, the Borrower shall execute and deliver an A Note in the principal amount of the Commitment of each new bank or other financial institution, or a replacement A Note in the principal amount of the increased Commitment of each Lender agreeing to increase its Commitment, as the case may be. Such A Notes and other documents of the nature referred to in Section 3.01 shall be furnished to the Agent in form and substance as may be reasonably required by it. Upon execution and delivery of such documents, such new bank or other financial institution shall constitute a "Lender" hereunder with a Commitment as specified therein, or such Lender's Commitment shall increase as specified therein, as the case may be. Before effecting any Increase by addition of any new bank or other financial institution, the Borrower will first offer the Lenders, by notice to them, the right to participate in such Increase by increasing their respective Commitments, and each Lender electing to participate in such Increase shall have the right to participate in such Increase (by increasing its Commitment in accordance with, and subject to, this Section 2.20) on a ratable basis.

SECTION 7.04. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on the financial statements referred to in Section 4.01 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.

Without limitation of the foregoing, each Lender (other than the Designated Bidders) agrees to reimburse the Agent promptly upon demand for its ratable share of any reasonable out-of-pocket expenses (including counsel fees) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings, in bankruptcy or insolvency proceedings, or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Agent acts in its capacity as Agent and is not reimbursed for such expenses by the Borrower. SECTION 7.06. Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be removed at any time with or without cause by the Majority Lenders.

If no successor Agent shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring Agent's giving of notice of resignation or the Majority Lenders' removal of the retiring Agent, then such retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a commercial bank organized, or authorized to conduct a banking business, 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.

(a) The Borrower hereby irrevocably submits to the jurisdiction of any New York State or Federal court sitting in New York City and any appellate court from any thereof in any action or proceeding by the Agent, the Arranger, any Lender or the holder of any Note in respect of, but only in respect of, any claims or causes of action arising out of or relating to this Agreement or the Notes (such claims and causes of action, collectively, being "Permitted Claims"), and the Borrower hereby irrevocably agrees that all Permitted Claims may be heard and determined in such New York State court or in such Federal court. The Borrower hereby irrevocably waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum to the maintenance of such action or proceeding in any aforementioned court in respect of Permitted Claims. The Borrower hereby irrevocably appoints CT Corporation System (the "Process Agent"), with an office on the date hereof at 1633 Broadway, New York, New York 10019, as its agent to receive on behalf of the Borrower and its property service of copies of the summons and complaint and any other process which may be served by the Agent, the Arranger, any Lender or the holder of any Note in any such action or proceeding in any aforementioned court in respect of Permitted Claims. Such service may be made by delivering a copy of such process to the Borrower by courier and by certified mail (return receipt requested), fees and postage prepaid, both (i) in care of the Process Agent at the Process Agent's above address and (ii) at the Borrower's address specified pursuant to Section 8.02, and the Borrower hereby irrevocably authorizes and directs the Process Agent to accept such service on its behalf. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. (b) Nothing in this Section 8.09 (i) shall affect the right of the Arranger, the Borrower, any Lender, the holder of any Note or the Agent to serve legal process in any other manner permitted by law or affect any right otherwise existing of the Borrower, any Lender, the Arranger, the holder of any Note or the Agent to bring any action or proceeding in the courts of other jurisdictions or (ii) shall be deemed to be a general consent to jurisdiction in any particular court or a general waiver of any defense or a consent to jurisdiction of the courts expressly referred to in subsection (a) above in any action or proceeding in respect of any claim or cause of action other than Permitted Claims. -70- 75 SECTION 8.10. Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York. SECTION 8.11. Execution in Counterparts.
