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, telefax or other teletransmission), in substantially the form of
Exhibit B 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
Administrative Agent at its address at Morgan, 60 Wall Street, 22nd Floor, New
York, New York 10260, Reference: Burlington Resources Inc., or at such other

funds and upon fulfillment of the 





                                       17
   22



applicable conditions set forth in Article 3, the Administrative Agent will make
such funds available to the Borrower at Morgan, 60 Wall Street, 22nd Floor, New
York, New York 10260, or at any account of the Borrower maintained by the
Administrative Agent (or any successor Administrative Agent) designated by the
Borrower and agreed to by the Administrative Agent (or such successor
Administrative Agent), in same day funds.

           (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 3, the
Borrower shall indemnify each Lender against any loss, cost or expense incurred
by such Lender as a result of such failure, including 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 Administrative 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 Administrative Agent such Lender's ratable portion of such A
Borrowing, the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the date of such A Borrowing in
accordance with subsection (a) of this Section 2.02 and the Administrative Agent
may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If and to the extent such Lender shall not have so
made such ratable portion available to the Administrative Agent, such Lender and
the Borrower severally agree to repay to the Administrative Agent forthwith on
demand such corresponding amount together with interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Administrative Agent, at the Effective Federal Funds
Rate for such day. If such Lender shall repay to the Administrative 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 2.6.  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 






                                       19
   24



         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 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 Administrative 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 2.7. 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 payable on the same
day or days on which interest is payable on such A Advance, at an interest rate
per annum up to but not exceeding at all times during each Interest Period for
such A Advance 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 such Interest Period over (ii)
the Eurodollar Rate for such Interest Period. Any Lender wishing to require
payment of such additional 





                                       20
   25



interest (x) shall so notify the Borrower and the Administrative Agent, in which
case such additional interest on the Eurodollar Rate Advances of such Lender
shall be payable to such Lender at the place indicated in such notice with
respect to each Interest Period commencing at least five Business Days after the
giving of such notice and (y) shall furnish to the Borrower at least five
Business Days prior to each date on which interest is payable on the Eurodollar
Rate Advances an officer's certificate setting forth the amount to which such
Lender is then entitled under this Section, which certificate shall be
conclusive and binding for all purposes, absent manifest error.

         SECTION 2.8.  Interest Rate Determination.

           (a Each Reference Bank agrees to furnish to the Administrative 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 Administrative Agent for the purpose of determining any such interest rate,
the Administrative Agent shall determine such interest rate on the basis of
timely information furnished by the remaining Reference Banks.

           (b The Administrative Agent shall give prompt notice to the Borrower
and the Lenders of the applicable interest rate determined by the Administrative
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 Administrative Agent for determining the Eurodollar Rate for any applicable
A Advances,

                   (i the Administrative 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 Administrative Agent shall notify the Borrower and
         the Lenders that the circumstances causing such suspension no longer
         exist.




                                       21
   26




           (d If, with respect to any Eurodollar Rate Advances, the Majority
Lenders determine and give notice to the Administrative Agent that as a result
of conditions in or generally affecting the relevant market, the rates of
interest determined on the 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 Administrative 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
         Administrative 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
Administrative 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 2.9. Voluntary Conversion of A Advances. The Borrower may on
any Business Day, upon notice given to the Administrative Agent, not later than
12:00 noon (New York City time) on the third Business Day prior to the date of
the proposed Conversion, and subject to the provisions of Section 2.08, 2.11 





                                       22
   27



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 2.10. Prepayments. The Borrower may, upon (i) in the case of
Eurodollar Rate Advances, at least three Business Days notice or (ii) in the
case of Base Rate Advances, telephonic notice not later than 12:00 noon (New
York City time) on the date of prepayment, to the Administrative Agent which
specifies the proposed date and aggregate principal amount of the prepayment and
the Type of A Advances to be prepaid, and if such notice is given the Borrower
shall, prepay the outstanding principal amounts of the A Advances comprising the
same A Borrowing in whole or ratably in part, together with accrued interest to
the date of such prepayment on the amount prepaid; provided, however, that (x)
each partial prepayment shall be in an aggregate principal amount not less than
$10,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in
the event of any such prepayment of Eurodollar Rate Advances on any day other
than the last day of an Interest Period for such Eurodollar Rate Advances, the
Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant
to, and to the extent required by, Section 8.04(b); provided, further, however,
that the Borrower will use its best efforts to give notice to the Administrative
Agent of the proposed prepayment of Base Rate Advances on the Business Day prior
to the date of such proposed prepayment.

         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 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 





                                       23
   28


the Administrative Agent), pay to the Administrative 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 Administrative
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 Administrative 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
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,
provided that such avoidance would not, in the reasonable judgment of such
Lender, be otherwise disadvantageous to such Lender.

           (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 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 





                                       24
   29



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 Administrative Agent), the Borrower shall pay to the
Administrative 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 Administrative 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 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 Administrative
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 Administrative 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 




                                       25
   30



reasonable efforts (including a reasonable effort to change its Applicable
Lending Office or to transfer its affected A Advances to an affiliate) to avoid
any such illegality, provided that such avoidance would not, in the reasonable
judgment of such Lender, be otherwise disadvantageous to such Lender.

         SECTION 2.14. Payments and Computations.

           (a The Borrower shall make each payment hereunder (including 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 Administrative 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 Administrative
Agent at Morgan, 60 Wall Street, 22nd Floor, New York, New York 10260,
Reference: Burlington Resources Inc., or at such other location designated by
notice to the Borrower from the Administrative 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 Administrative Agent, shall
be deemed duly made for all purposes of this Agreement and the Notes, except
that if at any time any such payment is rescinded or must otherwise be returned
by the Administrative 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 Administrative 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 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 Administrative Agent shall make all payments hereunder and under the 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 shall be made by the Administrative 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
Administrative 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,





                                       26
   31



on the basis of a year of 360 days, in each case for the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such interest or fees are payable. Each determination by the
Administrative Agent (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, 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 Administrative 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
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each 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
Administrative Agent, each Lender shall repay to the Administrative 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 Administrative
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 or profits, 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, 




                                       27
   32



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
Administrative Agent, as applicable) shall make such deductions at the
applicable statutory rate and (iii) the Borrower (or the Administrative 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 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, both (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) and (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 




                                       28
   33



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").

           (c The Borrower will indemnify each Indemnified Party for the full
amount of Taxes or Other Taxes (including 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 that is
not a United States person (as such term is defined in Section 7701(a)(30) of
the Internal Revenue Code) executes this Agreement or otherwise becomes an
"Indemnified Party" hereunder, such Indemnified Party shall provide the Borrower
and the Administrative 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 Administrative 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 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 







                                       29
   34


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 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 Administrative 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 (A) the amount of such Lender's required
repayment to (B) 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 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 Advances shall be
evidenced by a Note payable to the order of such Lender and delivered hereunder
by the Borrower. Notwithstanding the provisions of the 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 Advances and payments made from time to time hereunder
and under the Note payable to its order. In any legal action or proceeding in
respect of this Agreement or such 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 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) the date falling 30 days prior to the Stated
Termination Date, 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 Administrative Agent, by telecopy, telefax or
         other teletransmission, a notice of a B Borrowing (a "NOTICE OF B
         BORROWING"), in substantially the form of Exhibit C 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 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) the
         Stated Termination Date), 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 




                                       31
   36





         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 Administrative 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 Administrative 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 maximum amount of each B Advance which such
         Lender would be willing to make as part of such proposed B Borrowing
         (which amount 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
         Administrative 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 Administrative
         Agent by the other Lenders. If any Lender shall elect not to make such
         an offer, such Lender shall so notify the Administrative 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 Administrative Agent by the other
         Lenders, and such Lender shall not be obligated to, and shall not, make
         any B 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





                                       32
   37



         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
                  Administrative 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 Administrative 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
                  Administrative 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 Administrative Agent notice to that effect.

                 (iv) If the Borrower notifies the Administrative Agent that
         such B Borrowing is cancelled pursuant to paragraph (iii)(A) above, the
         Administrative 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 paragraph (iii)(B) above, the
         Administrative 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
         Administrative Agent has received forms of documents appearing to
         fulfill the applicable conditions set forth in Article 3. Each Lender
         that is to 




                                       33
   38




         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 Administrative Agent pursuant to clause (A) of
         the preceding sentence or any later time when such Lender shall have
         received notice from the Administrative Agent pursuant to clause (C) of
         the preceding sentence, make available for the account of its
         Applicable Lending Office to the Administrative Agent at its address
         referred to in Section 8.02 such Lender's portion of such B Borrowing,
         in same day funds. Upon fulfillment of the applicable conditions set
         forth in Article 3 and after receipt by the Administrative Agent of
         such funds, the Administrative Agent will make such funds available to
         the Borrower at the Administrative Agent's aforesaid address. Promptly
         after each B Borrowing the Administrative 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 Administrative Agent for the
account of each Lender which has made a B Advance, or each other holder of a
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 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 Note 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 Note evidencing such B Advance, subject to Section 2.06(b)

         (e) Each time that the Borrower gives a Notice of B Borrowing, the
Borrower shall pay to the Administrative Agent for its own account such fee as
may be agreed between the Borrower and the Administrative Agent from time to
time, whether or not any B Borrowing is in fact made.





                                       34
   39

         (f) 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).

         (g) 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
Administrative Agent.

         SECTION 2.20. Increase of Commitments. (a) At any time after the
Effective Date, provided that no Event of Default shall have occurred and be
continuing, the Borrower may request an increase of the aggregate Commitments by
notice to the Administrative Agent in writing of the amount (the "OFFERED
INCREASE AMOUNT") of such proposed increase (such notice, a "COMMITMENT INCREASE
NOTICE"). Any such Commitment Increase Notice must offer each Lender the
opportunity to subscribe for its pro rata share of the increased Commitments. If
any portion of the increased Commitments is not subscribed for by the Lenders,
the Borrower may, in its sole discretion, but with the consent of the
Administrative Agent as to any Person that is not at such time a Lender (which
consent shall not be unreasonably withheld), offer to any existing Lender or to
one or more additional banks or financial institutions the opportunity to
participate in all or a portion of such unsubscribed portion of the increased
Commitments pursuant to paragraph (b) or (c) below, as applicable.

          (b) Any additional bank or financial institution that the Borrower
selects to offer participation in the increased Commitments, and that elects to
become a party to this Agreement and obtain a Commitment, shall execute a New
Lender Agreement with the Borrower and the Administrative Agent, substantially
in the form of Exhibit E (a "NEW LENDER AGREEMENT"), whereupon such bank or
financial institution (a "NEW LENDER") shall become a Lender for all purposes
and to the same extent as if originally a party hereto and shall be bound by and
entitled to the benefits of this Agreement, and the signature pages hereof shall
be deemed to be amended to add the name and Commitment of such New Lender,
provided that the Commitment of any such New Lender shall be in an amount not
less than $10,000,000.



                                       35
   40






          (c) Any Lender that accepts an offer to it by the Borrower to increase
its Commitment pursuant to this Section 2.20 shall, in each case, execute a
Commitment Increase Agreement with the Borrower and the Administrative Agent,
substantially in the form of Exhibit F (a "COMMITMENT INCREASE AGREEMENT"),
whereupon such Lender shall be bound by and entitled to the benefits of this
Agreement with respect to the full amount of its Commitment as so increased, and
the signature pages hereof shall be deemed to be amended to so increase the
Commitment of such Lender.

          (d) The effectiveness of any New Lender Agreement or Commitment
Increase Agreement shall be contingent upon receipt by the Administrative Agent
of such corporate resolutions of the Borrower and legal opinions of counsel to
the Borrower as the Administrative Agent shall reasonably request with respect
thereto, in each case, in form and substance satisfactory to the Administrative
Agent.

          (e) If any bank or financial institution becomes a New Lender pursuant
to Section 2.20(b) or any Lender's Commitment is increased pursuant to Section
2.20(c), additional A Advances made on or after the effectiveness thereof (the
"RE-ALLOCATION DATE") shall be made pro rata based on the Commitment Percentages
in effect on and after such Re-Allocation Date (except to the extent that any
such pro rata borrowings would result in any Lender making an aggregate
principal amount of A Advances in excess of its Commitment, in which case such
excess amount will be allocated to, and made by, such New Lender and/or Lenders
with such increased Commitments to the extent of, and pro rata based on, their
respective Commitments), and continuations of Eurodollar Rate Advances
outstanding on such Re-Allocation Date shall be effected by repayment of such
Eurodollar Rate Advances on the last day of the Interest Period applicable
thereto and the making of new Eurodollar Rate Advances pro rata based on such
new Commitment Percentages. In the event that on any such Re-Allocation Date
there is an unpaid principal amount of Base Rate Advances, the Borrower shall
make prepayments thereof and borrowings of Base Rate Advances so that, after
giving effect thereto, the Base Rate Advances outstanding are held pro rata
based on such new Commitment Percentages. In the event that on any such
Re-Allocation Date there is an unpaid principal amount of Eurodollar Rate
Advances, such Eurodollar Rate Advances shall remain outstanding with the
respective holders thereof until the expiration of their respective Interest
Periods (unless the applicable Borrower elects to prepay any thereof in
accordance with the applicable provisions of this Agreement), and interest on
and repayments of such Eurodollar Rate Advances will be paid thereon to the
respective Lenders holding such Eurodollar Rate Advances pro rata based on the
respective principal amounts thereof outstanding.




                                       36
   41




          (f) Notwithstanding anything to the contrary in this Section 2.20, (i)
no increase pursuant to this Section 2.20 shall be effective without the consent
of the Required Lenders, (ii) no Lender shall have any obligation to increase
its Commitment unless it agrees to do so in its sole discretion and (iii) the
aggregate amount by which the Commitments hereunder are increased pursuant to
this Section 2.20 shall not exceed $180,000,000.

          (g) The Borrower shall execute and deliver a Note to each new bank or
other financial institution becoming a Lender.

         SECTION 2.21. Extension of Stated Termination Date. (a) Not later than
45 days prior to the Stated Termination Date then in effect, provided that no
Event of Default shall have occurred and be continuing, the Borrower may request
an extension of such Stated Termination Date by submitting to the Administrative
Agent an Extension Request containing the information in respect of such
extension specified in Exhibit G, which the Administrative Agent shall promptly
furnish to each Lender. Each Lender shall, no later than 30 days after receiving
from the Administrative Agent the applicable Extension Request, notify the
Borrower and the Administrative Agent of its election to extend or not extend
the Stated Termination Date as requested in such Extension Request. If the
Required Lenders shall approve in writing the extension of the Stated
Termination Date requested in such Extension Request, the Stated Termination
Date shall automatically and without any further action by any Person be
extended for the period specified in such Extension Request; provided that (i)
each extension pursuant to this Section 2.21 shall be for a maximum of one year,
(ii) the Commitment of any Lender that does not consent in writing within 30
days after receiving from the Administrative Agent the applicable Extension
Request (an "OBJECTING LENDER") shall, unless earlier terminated in accordance
with this Agreement, expire on the Stated Termination Date in effect on the date
of such Extension Request (such Stated Termination Date, if any, referred to as
the "COMMITMENT EXPIRATION DATE" with respect to such Objecting Lender) and
(iii) the Borrower may exercise no more than two extensions pursuant to this
Section 2.21, so that the Stated Termination Date shall not in any event extend
beyond the second anniversary of the initial Stated Termination Date hereunder.
If, within 30 days after receiving from the Administrative Agent the applicable
Extension Request, the Required Lenders shall not approve in writing the
extension of the Stated Termination Date requested in an Extension Request, the
Stated Termination Date shall not be extended pursuant to such Extension
Request. The Administrative Agent shall promptly notify (y) the Lenders and the
Borrower of any extension of the Stated Termination Date pursuant to this
Section 2.21 and (z) the Borrower of any Lender that becomes an Objecting
Lender.





                                       37
   42



          (b) A Advances owing to any Objecting Lender on the Commitment
Expiration Date, together with accrued interest thereon, any amounts payable
pursuant to Sections 2.06, 2.07, 2.11, 2.12, 2.15 and 8.04(b) and any accrued
and unpaid facility fee or other amounts payable with respect to such Lender
shall be repaid in full on or before such Commitment Expiration Date.

          (c) The Borrower shall have the right, so long as no Event of Default
has occurred and is then continuing, upon giving notice to the Administrative
Agent and the Objecting Lenders in accordance with Section 2.10, to prepay in
full the A Advances of the Objecting Lenders, together with accrued interest
thereon, any amounts payable pursuant to Sections 2.06, 2.07, 2.11, 2.12, 2.15
and 8.04(b) and any accrued and unpaid facility fee or other amounts payable to
the Objecting Lenders hereunder and, upon giving not less than three Business
Days' notice to the Objecting Lenders and the Administrative Agent, to cancel
the whole or part of the Commitments of the Objecting Lenders.

          (d) Notwithstanding the foregoing, if any Lender becomes an Objecting
Lender, the Borrower may, at its own expense and in the sole discretion and
prior to the then Stated Termination Date, require such Lender (and each related
Designated Bidder (as defined herein or in the Short-Term Revolving Credit
Agreement)) to transfer or assign, in whole or in part, without recourse (in
accordance with Section 8.07), all or part of its interests, rights and
obligations under this Agreement and the Short-Term Revolving Credit Agreement
to an Eligible Assignee (provided that the Borrower, with the full cooperation
of such Lender, can identify an Eligible Assignee that is ready, willing and
able to be an assignee with respect thereto) which shall assume such assigned
obligations (which assignee may be another Lender, if such assignee Lender
accepts such assignment); provided that (A) the assignee or the Borrower, as the
case may be, shall have paid to such Lender in immediately available funds the
principal of and interest accrued to the date of such payment on the Advances
made by it hereunder and the "Advances" made by it under, and as defined in, the
Short-Term Revolving Credit Agreement and all other amounts owed to it hereunder
and thereunder, including any amounts owing pursuant to Section 8.04(b) (or the
comparable provision of the Short-Term Revolving Credit Agreement) and any
amounts that would be owing under such Section (or comparable provision) if such
Advances and "Advances" (as so defined) were prepaid on the date of such
assignment, and (B) such assignment does not conflict with any law, rule or
regulation or order of any governmental authority. Any assignee that becomes a
Lender as a result of such an assignment made pursuant to this paragraph (d)
shall be deemed to have consented to the applicable Extension Request and,
therefore, shall not be an Objecting Lender.

         SECTION 2.22. Replacement of Lenders. If any Lender requests
compensation under Sections 2.07, 2.11 or 2.12 or if the Borrower is required to
pay any additional amount to any Lender or any taxing authority or other
authority for the account of any Lender pursuant to Section 2.15, or if any
Lender suspends the right of the Borrower to elect Eurodollar Rate Advances from
such Lender pursuant to Section 2.13, or if any Lender defaults in its
obligation to fund Advances hereunder, then the Borrower may, at its sole
expense and effort, upon notice to such Lender and the Administrative Agent,
require such Lender to assign and delegate, without recourse (in accordance with
and subject to the restrictions contained in Section 8.07), all its interests,
rights and obligations under this Agreement (other than any outstanding B
Advances held by it) and the Short-Term Revolving Credit Agreement (other than
"B Advances" under, and as defined in, the Short-Term Revolving Credit
Agreement) to an assignee that shall assume such obligations (which assignee may
be another Lender, if a Lender accepts such assignment); provided that (i) the
Borrower shall have received the prior written consent of the Administrative
Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall
have received payment of an amount equal to the outstanding principal of its
Advances (other than B Advances) hereunder and its "Advances" (other than "B
Advances") (each as defined in the Short-Term Revolving Credit Agreement),
accrued interest thereon, accrued fees, accrued costs in connection with
compensation under Sections 2.07, 2.11 or 2.12 or payments required to be made
pursuant to Section 2.15, if any, and all other amounts payable to it hereunder
and thereunder, from the assignee (to the extent of such outstanding principal
and accrued interest and fees) or the Borrower (in the case of all other
amounts) and (iii) in the case of any such assignment resulting from a claim for
compensation under Sections 2.07, 2.11 or 2.12 or payments required to be made
pursuant to Section 2.15, such assignment will result in a reduction in such
compensation or payments. A Lender shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such
Lender or otherwise, the circumstances entitling the Borrower to require such
assignment and delegation cease to apply.

                         REPRESENTATIONS AND WARRANTIES

         SECTION 4.1. Representations and Warranties of the Borrower. The
Borrower represents and warrants as follows:

          (a) The Borrower is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware. Each Material
Subsidiary is duly incorporated, validly existing and in good standing in the
jurisdiction of its incorporation. The Borrower and each Material Subsidiary
possess all corporate powers and all other authorizations and licenses necessary
to engage in its business and operations as now conducted, the failure to obtain
or maintain which would have a Material Adverse Effect. Each Subsidiary which
is, on and as of the date of this Agreement, a Material Subsidiary is listed on
Schedule I hereto.

          (b) The execution, delivery and performance by the Borrower of this
Agreement and the Notes are within the Borrower's corporate powers, have been
duly authorized by all necessary corporate action, and do not contravene (i) the
Borrower's certificate of incorporation or by-laws or (ii) law or any
contractual restriction binding on or affecting the Borrower.

          (c) No authorization or approval or other action by, and no notice to
or filing with, any governmental authority or regulatory body is required for
the due 




                                       42
   47



execution, delivery and performance by the Borrower of this Agreement or the
Notes which has not been duly made or obtained, except those (i) required in the
ordinary course to comply with ongoing covenant obligations of the Borrower
hereunder the performance of which is not yet due and (ii) that will, in the
ordinary course of business in accordance with this Agreement, be duly made or
obtained on or prior to the time or times the performance of such obligations
shall be due.

          (d) This Agreement constitutes, and the Notes when delivered hereunder
shall constitute, legal, valid and binding obligations of the Borrower
enforceable against the Borrower in accordance with their respective terms,
except as may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting creditors rights generally or by
general principles of equity.

          (e) The consolidated balance sheet of the Borrower and its
consolidated Subsidiaries as at December 31, 1997 and the related consolidated
statements of income and cash flow for the fiscal year then ended, reported on
by Coopers & Lybrand, independent public accountants, copies of which have been
furnished to the Administrative Agent and the Initial Lenders prior to the date
hereof, fairly present the consolidated financial condition of the Borrower and
such Subsidiaries as at December 31, 1997 and the consolidated results of their
operations for such fiscal period, all in accordance with generally accepted
accounting principles consistently applied. From December 31, 1997 to and
including the Effective Date there has been no material adverse change in such
condition or results of operations.

          (f) As at the Effective Date, there is no action, suit or proceeding
pending, or to the knowledge of the Borrower threatened, against or involving
the Borrower or any Material Subsidiary in any court, or before any arbitrator
of any kind, or before or by any governmental body, which in the reasonable
judgment of the Borrower (taking into account the exhaustion of all appeals)
would have a material adverse effect on the consolidated financial condition of
the Borrower and its consolidated Subsidiaries taken as a whole, or which
purports to affect the legality, validity, binding effect or enforceability of
this Agreement or the Notes.

          (g) The Borrower and each consolidated Subsidiary have duly filed all
tax returns required to be filed, and duly paid and discharged all taxes,
assessments and governmental charges upon it or against its properties now due
and payable, the failure to file or pay which, as applicable, would have a
Material Adverse Effect, unless and to the extent only that the same are being
contested in good faith and by appropriate proceedings by the Borrower or the
appropriate Subsidiary.




                                       43
   48



          (h) Except to the extent permitted pursuant to Section 5.02(e),
neither the Borrower nor any Material Subsidiary is subject to any contractual
restrictions which limit the amount of dividends payable by any Subsidiary.

          (i) No Termination Event has occurred or is reasonably expected to
occur with respect to any Plan which, with the giving of notice or lapse of
time, or both, would constitute an Event of Default under Section 6.01(g).

          (j) Neither the Borrower nor any ERISA Affiliate has incurred, or is
reasonably expected to incur, any Withdrawal Liability to any Multiemployer Plan
that, when aggregated with all other amounts required to be paid to
Multiemployer Plans in connection with Withdrawal Liability (as of the date of
determination), exceeds 5% of the Consolidated Tangible Net Worth of the
Borrower.

          (k) Neither the Borrower nor any ERISA Affiliate has received any
notification that any Multiemployer Plan is in reorganization or has been
terminated, within the meaning of Title IV of ERISA, and no Multiemployer Plan
is reasonably expected to be in reorganization or to be terminated within the
meaning of Title IV of ERISA the effect of which reorganization or termination
would be the occurrence of an Event of Default under Section 6.01(i).

          (l) The Borrower is not an "investment company" or a "company"
controlled by an "investment company" within the meaning of the Investment
Company Act of 1940, as amended.

          (m) The Borrower is not a "holding company" or a "subsidiary company"
of a "holding company", or an "affiliate" of a "holding company" or of a
"subsidiary company" of a "holding company", or a "public utility" within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

All representations and warranties made by the Borrower herein or made in any
certificate delivered pursuant hereto shall survive the making of the Advances
and the execution and delivery to the Lenders of this Agreement and the Notes.

                            COVENANTS OF THE BORROWER

         SECTION 5.1. Affirmative Covenants. So long as any Note or other amount
payable by the Borrower hereunder shall remain unpaid or any Lender 





                                       44
   49



shall have any Commitment hereunder, the Borrower will, unless the Majority
Lenders shall otherwise consent in writing:

          (a) PRESERVATION OF CORPORATE EXISTENCE, ETC. Preserve and maintain,
and cause each Material Subsidiary to preserve and maintain, its corporate
existence, rights (charter and statutory) and material franchises, except as
otherwise permitted by Section 5.02(c) or 5.02(d).

          (b) COMPLIANCE WITH LAWS, ETC. Comply, and cause each Subsidiary to
comply, in all material respects, with all applicable laws, rules, regulations
and orders (including all environmental laws and laws requiring payment of all
taxes, assessments and governmental charges imposed upon it or upon its property
except to the extent contested in good faith by appropriate proceedings) the
failure to comply with which would have a Material Adverse Effect.

          (c) VISITATION RIGHTS. At such reasonable times and intervals as the
Administrative Agent or any of the Lenders (other than Designated Bidders) may
desire, permit the Administrative Agent or any of the Lenders (other than
Designated Bidders) to visit the Borrower and to discuss the affairs, finances,
accounts and mineral reserve performance of the Borrower and any of its
Subsidiaries with officers of the Borrower and independent certified public
accountants of the Borrower and any of its Subsidiaries, provided that if an
Event of Default, or an event which with the giving of notice or the passage of
time, or both, would become an Event of Default, has occurred and is continuing,
the Administrative Agent or any Lender may, in addition to the other provisions
of this subsection (c) and at such reasonable times and intervals as the
Administrative Agent or any of the Lenders may desire, visit and inspect, under
guidance of officers of the Borrower, any properties significant to the
consolidated operations of the Borrower and its Subsidiaries, and to examine the
books and records of account (other than with respect to any mineral reserve
information that the Borrower determines to be confidential) of the Borrower and
any of its Subsidiaries and to discuss the affairs, finances and accounts of any
of the Borrower's Subsidiaries with any of the officers of such Subsidiary.

          (d) BOOKS AND RECORDS. Keep, and cause each of its Subsidiaries to
keep, proper books of record and account, in which full and correct entries
shall be made of all financial transactions and the assets and business of the
Borrower and each Subsidiary in accordance with generally accepted accounting
principles either (i) consistently applied or (ii) applied in a changed manner
that does not, under generally accepted accounting principles or public
reporting requirements applicable to the Borrower, either require disclosure in
the consolidated financial statements of the Borrower and its consolidated
Subsidiaries or require the consent of the accountants which (as required by
Section 5.03(b)) report on such 





                                       45
   50



financial statements for the fiscal year in which such change shall have
occurred, or (iii) applied in a changed manner not covered by clause (ii) above
provided such change shall have been disclosed to the Administrative Agent and
shall have been consented to by the accountants which (as required by Section
5.03(b)) report on the consolidated financial statements of the Borrower and its
consolidated Subsidiaries for the fiscal year in which such change shall have
occurred, provided that if any change referred to in clause (ii) or (iii) above
would not meet the standard set forth in clause (i) or (ii) of Section 1.03, the
Administrative Agent, the Lenders and the Borrower agree to amend the covenants
contained in Section 5.01 and 5.02 so that the relative protection afforded
thereby to the Lenders and the relative flexibility afforded thereby to the
Borrower will in substance be retained after such amendment, provided, however,
that until such amendment becomes effective hereunder, the covenants as set
forth herein shall remain in full force and effect and those accounting
principles applicable to the Borrower and its consolidated Subsidiaries which do
meet the standards set forth in clause (i) or (ii) of Section 1.03 shall be
applied to determine whether or not the Borrower is in compliance with such
covenants.

          (e) MAINTENANCE OF PROPERTIES, ETC. Maintain and preserve, and cause
each Material Subsidiary to maintain and preserve, all of its properties which
are used in the conduct of its business in good working order and condition,
ordinary wear and tear excepted, to the extent that any failure to do so would
have a Material Adverse Effect.

          (f) MAINTENANCE OF INSURANCE. Maintain, and cause each Material
Subsidiary to maintain, insurance with responsible and reputable insurance
companies or associations in such amounts and covering such risks as is usually
carried by companies engaged in similar businesses and owning similar properties
in the same general areas in which the Borrower or such Subsidiary operates.

         SECTION 5.2. Negative Covenants. So long as any Note or other amount
payable by the Borrower hereunder shall remain unpaid or any Lender shall have
any Commitment hereunder, the Borrower will not, unless the Majority Lenders
shall otherwise consent in writing:

          (a) LIENS, ETC. (i) Create, assume or suffer to exist, or permit any
Material Subsidiary to create, assume or suffer to exist, any Liens upon or with
respect to any of the Equity Interests in any Material Subsidiary, whether now
owned or hereafter acquired, or (ii) create or assume, or permit any Material
Subsidiary to create or assume, any Liens upon or with respect to any other
assets material to the consolidated operations of the Borrower and its
consolidated Subsidiaries taken as a whole securing the payment of Debt and
Guaranties in an aggregate amount (determined without duplication of amount (so
that the amount 




                                       46
   51


of a Guaranty will be excluded to the extent the Debt Guaranteed thereby is
included in computing such aggregate amount)) exceeding the greater of (x)
$250,000,000 and (y) 10% of Consolidated Tangible Net Worth as at the date of
such creation or assumption; provided, however, that this subsection (a) shall
not apply to:

                  of its Subsidiaries after the Original Effective Date to the
                  extent that such Liens existed at the time of such acquisition
                  and were not placed thereon by or with the consent of the
                  Borrower in contemplation of such acquisition;

                           (B) Liens on Equity Interests acquired after the
                  Original Effective Date in a Business Entity which has become
                  or becomes a Subsidiary of the Borrower, or on assets of any
                  such Business Entity, to the extent that such Liens existed at
                  the time of such acquisition and were not placed thereon by or
                  with the consent of the Borrower in contemplation of such
                  acquisition;

                           (C)   Liens on Margin Stock;

                           (E)   Permitted Liens;

                  Lien permitted by any of the foregoing clauses of this
                  Section, provided that the principal amount of such Debt or
                  Guaranty is not increased (except by the amount of costs
                  reasonably incurred in connection with the issuance thereof)
                  and such Debt or Guaranty is not secured by any additional
                  assets that would not have been permitted by this Section to
                  secure the Debt or Guaranty refinanced, extended, renewed or

          (b) DEBT, ETC. Create, assume or suffer to exist, or permit any of its
consolidated Subsidiaries to create, assume or suffer to exist, any Debt or any
Guaranty unless, immediately after giving effect to such Debt or Guaranty and

connection therewith,

                            (1) the sum (without duplication) of (i)
                  consolidated Debt of the Borrower and its consolidated

                  commercial banks and trust companies (other than Debt incurred
                  pursuant to this Agreement or the Short-Term Revolving Credit
                  Agreement or any replacement therefor), shall not exceed the
                  aggregate of the Borrower's unused bank lines of credit and
                  unused credit available to the Borrower under financing
                  arrangements with banks or other financial institutions; and

                            (2) with respect to any such Debt created or assumed
                  by a consolidated Subsidiary that is either a Subsidiary of
                  the Borrower as of the Original Effective Date or a Subsidiary
                  of the Borrower acquired or created after the Original
                  Effective Date and owning a material portion of the
                  consolidated operating assets existing at the Original

waived by the Borrower; provided, however, that if an Event of Default under
subsection (e) of this Section 6.01 (except under clause (i)(A) thereof) shall

                            THE ADMINISTRATIVE AGENT

         SECTION 7.1. Authorization and Action. Each Lender hereby appoints and
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. As to any matters not expressly provided for by
this Agreement (including enforcement of this Agreement or collection of the





                                       56
   61



Notes), the Administrative Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Majority Lenders, and such instructions shall be
binding upon all Lenders and all holders of Notes; provided, however, that the
Administrative Agent shall not be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this
Agreement or applicable law. The Administrative Agent agrees to give to each
Lender prompt notice of each notice given to it by the Borrower pursuant to the
terms of this Agreement.

         SECTION 7.2. Administrative Agent's Reliance, Etc.. Neither the
Administrative Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under
or in connection with this Agreement, except for its or their own gross
negligence or willful misconduct. Without limitation of the generality of the
foregoing, the Administrative Agent: (i) may treat the payee of any Note as the
holder thereof until the Administrative Agent receives and accepts an Assignment
and Acceptance entered into by the Lender which is the payee of such Note, as
assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07;
(ii) may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in

Lender for any statements, warranties or representations (whether written or
oral) made in or in connection with this Agreement; (iv) shall not have any duty

terms, covenants or conditions of this Agreement on the part of the Borrower or
to inspect the property (including the books and records) of the Borrower; (v)
shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
any other instrument or document furnished pursuant hereto; and (vi) shall incur
no liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telegram,
telecopy, cable or telex) believed by it to be genuine and signed or sent by the
proper party or parties.

         SECTION 7.3. Morgan and Affiliates. With respect to its Commitments,
the Advances made by it and the Notes issued to it, Morgan shall have the same
rights and powers under this Agreement as any other Lender and may exercise the
same as though it were not the Administrative Agent; and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include Morgan in its
individual capacity. Morgan and its affiliates may accept deposits from, lend
money to, act as trustee under indentures of, and generally engage in any kind
of 




                                       57
   62



business with, the Borrower, any of its Subsidiaries and any Person who may do
business with or own securities of the Borrower or any Subsidiary, all as if
Morgan were not the Administrative Agent and without any duty to account
therefor to the other Lenders.

         SECTION 7.4. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Administrative 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. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement.

         SECTION 7.5. Indemnification. THE LENDERS (OTHER THAN THE DESIGNATED
BIDDERS) AGREE TO INDEMNIFY THE ADMINISTRATIVE AGENT (TO THE EXTENT NOT
REIMBURSED BY THE BORROWER), RATABLY ACCORDING TO THE RESPECTIVE PRINCIPAL
AMOUNTS OF THE NOTES THEN HELD BY EACH OF THEM (OR IF NO NOTES ARE AT THE TIME
OUTSTANDING OR IF ANY NOTES ARE HELD BY PERSONS WHICH ARE NOT LENDERS, RATABLY
ACCORDING TO THE RESPECTIVE AMOUNTS OF THEIR COMMITMENTS OR THE RESPECTIVE
AMOUNTS OF THEIR COMMITMENTS IMMEDIATELY PRIOR TO TERMINATION IF THE COMMITMENTS
HAVE BEEN TERMINATED), FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS,
LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND
DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED
BY, OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT IN ANY WAY RELATING TO OR
ARISING OUT OF THIS AGREEMENT, ANY OF THE NOTES OR ANY OTHER INSTRUMENT OR
DOCUMENT FURNISHED PURSUANT HERETO OR IN CONNECTION HEREWITH, OR ANY ACTION
TAKEN OR OMITTED BY THE ADMINISTRATIVE AGENT UNDER THIS AGREEMENT, OR ANY OF THE
NOTES OR ANY OTHER INSTRUMENT OR DOCUMENT FURNISHED PURSUANT HERETO OR IN
CONNECTION HEREWITH; PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY PORTION OF
SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM THE ADMINISTRATIVE
AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. 





                                       58
   63




Without limitation of the foregoing, each Lender (other than the Designated
Bidders) agrees to reimburse the Administrative Agent promptly upon demand for
such Lender's ratable share of any reasonable out-of-pocket expenses (including
counsel fees) incurred by the Administrative 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, any of the Notes or any other
instrument or document furnished pursuant hereto or in connection herewith to
the extent that the Administrative Agent acts in its capacity as Administrative
Agent and is not reimbursed for such expenses by the Borrower.

         SECTION 7.6. Successor Administrative Agent. The Administrative 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. Upon any such resignation or removal, the Majority Lenders shall have
the right to appoint a successor Administrative Agent. If no successor
Administrative Agent shall have been so appointed by the Majority Lenders, and
shall have accepted such appointment, within 30 days after the retiring
Administrative Agent's giving of notice of resignation or the Majority Lenders'
removal of the retiring Administrative Agent, then such retiring Administrative
Agent may, on behalf of the Lenders, appoint a successor Administrative 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. Upon the

Administrative Agent, the provisions of this Article 7 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement.

notwithstanding the absence of written confirmation or any contradictory
provision thereof.

         SECTION 8.3. No Waiver; Remedies. No failure on the part of any Lender
or the Administrative Agent to exercise, and no delay in exercising, any right
hereunder or under any Note shall operate as a waiver thereof; nor shall any

provided by law.

         SECTION 8.4.  Costs and Expenses; Indemnity.

          (a) The Borrower agrees to pay on demand (i) all reasonable fees and

the other documents to be delivered hereunder and with respect to advising the
Administrative Agent as to its rights and responsibilities under this Agreement,

counsel for the Administrative Agent or its Affiliates, travel expenses,
duplication and printing costs and courier and postage fees, and excluding any
syndication fees paid to other parties joining the syndicate and (iii) all
out-of-pocket costs and expenses, if any, of the Administrative Agent and the

of in-house counsel), in connection with the enforcement (whether through
negotiations, legal proceedings, in bankruptcy or insolvency proceedings, or
otherwise) of this Agreement, the Notes and the other documents to be delivered
hereunder and thereunder.

          (b) If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance is made by the Borrower to or for the account of a Lender on any
day other than the last day of the Interest Period for such Advance, as a result
of a prepayment pursuant to Section 2.10 or a Conversion pursuant to Section
2.08(f) or Section 2.09 or due to acceleration of the maturity of the Notes
pursuant to Section 6.01 or due to any other reason attributable to the
Borrower, the Borrower shall, upon demand by such Lender (with a copy of such
demand to the Administrative Agent), pay to the Administrative Agent for the
account of such Lender any amounts required to compensate such Lender for any
additional 





                                       61
   66




losses, costs or expenses which it may reasonably incur as a result of such
payment or Conversion, including any loss (excluding loss of anticipated
profits), cost or expense incurred by reason of the liquidation or reemployment
of deposits or other funds acquired by any Lender to fund or maintain such
Advance.

          (c) THE BORROWER AGREES TO INDEMNIFY AND HOLD HARMLESS THE
ADMINISTRATIVE AGENT, THE ARRANGER AND EACH LENDER FROM AND AGAINST ANY AND ALL
CLAIMS, DAMAGES, LIABILITIES AND EXPENSES (INCLUDING FEES AND DISBURSEMENTS OF
COUNSEL) WHICH MAY BE INCURRED BY OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT,
THE ARRANGER OR SUCH LENDER IN CONNECTION WITH OR ARISING OUT OF ANY
INVESTIGATION, LITIGATION, OR PROCEEDING (WHETHER OR NOT THE ADMINISTRATIVE
AGENT, THE ARRANGER OR SUCH LENDER IS PARTY THERETO) RELATED TO ANY ACQUISITION
OR PROPOSED ACQUISITION BY THE BORROWER, OR BY ANY SUBSIDIARY OF THE BORROWER,
OF ALL OR ANY PORTION OF THE EQUITY INTERESTS IN, OR SUBSTANTIALLY ALL THE
ASSETS OF, ANY PERSON OR ANY USE OR PROPOSED USE OF THE ADVANCES BY THE BORROWER
(EXCLUDING ANY CLAIMS, DAMAGES, LIABILITIES OR EXPENSES INCURRED BY REASON OF
THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PARTY TO BE INDEMNIFIED OR ITS
EMPLOYEES OR ADMINISTRATIVE AGENTS, OR BY REASON OF ANY USE OR DISCLOSURE OF
INFORMATION RELATING TO ANY SUCH ACQUISITION OR USE OR PROPOSED USE OF THE
PROCEEDS BY THE PARTY TO BE INDEMNIFIED OR ITS EMPLOYEES OR ADMINISTRATIVE
AGENTS).

         SECTION 8.5. Right of Set-off. Upon the declaration of the Notes as due
and payable pursuant to the provisions of Section 6.01, each Lender is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender to or for the credit or the account of the Borrower
against any and all of the obligations of the Borrower now or hereafter existing
under this Agreement and any Note held by such Lender, irrespective of whether
or not such Lender shall have made any demand under this Agreement or such Note
and although such obligations may be unmatured. Each Lender agrees promptly to
notify the Borrower after any such set-off and application made by such Lender,
provided that the failure to give such notice shall not affect the validity of
such set-off and application. The rights of each Lender under this Section 8.05
are in addition to other rights and remedies (including other rights of set-off)
which such Lender may have.

         SECTION 8.6. Binding Effect. This Agreement shall become effective in
accordance with the provisions of Section 3.01, and thereafter shall be binding
upon and inure to the benefit of the Borrower, the Administrative Agent, the
Arranger and each Lender and their respective successors and assigns, except
that the Borrower shall not have the right to assign its rights hereunder or any
interest herein without the prior written consent of all of the Lenders.

         SECTION 8.7.  Assignments and Participations.

          (a) Each Lender (other than a Designated Bidder) may assign to one or
more banks or other financial institutions all or a portion of its rights and
obligations under this Agreement (including all or a portion of its Commitment,
the A Advances owing to it and the Note or Notes held by it); provided, however,
that (i) each such assignment shall be of a constant, and not a varying,
percentage of all rights and obligations under this Agreement (other than any
right to make B Advances, any B Advances or any Notes), and the same constant
percentage of all rights and obligations of such assigning Lender under the
Short-Term Revolving Credit Agreement, unless the Short-Term Revolving Credit
Agreement has been terminated, shall be contemporaneously assigned by such
assigning Lender to the same assignee pursuant to Section 8.07(a) of the
Short-Term Revolving Credit Agreement, (ii) the sum of (x) the amount of the
Commitment of the assigning Lender being assigned to the assignee pursuant to
each such assignment (determined as of the date of the Assignment and Acceptance
with respect to such assignment) plus (y) the amount of the "Commitment" of the
assigning Lender under the Short-Term Revolving Credit Agreement
contemporaneously assigned by such assigning Lender to such assignee as
contemplated by clause (i) of this sentence must be equal to or greater than
$25,000,000 (unless the Borrower and the Administrative Agent shall otherwise
consent, which consent may be withheld for any reason) and must be an integral
multiple of $1,000,000, (iii) each such assignment shall be to an Eligible
Assignee, and (iv) the parties to each such assignment shall execute and deliver
to the Administrative Agent, for its acceptance and recording in the Register,
an Assignment and Acceptance, together with any Note or Notes subject to such
assignment and a processing and recordation fee of $3,000, and shall send to the
Borrower an executed counterpart of such Assignment and Acceptance. Upon such
execution, delivery, acceptance and recording, from and after the effective date
specified in each Assignment and Acceptance, (x) the assignee thereunder shall
be a party hereto and, to the extent that rights and obligations hereunder have
been assigned to it pursuant to such Assignment and Acceptance, have the rights
and obligations of a Lender hereunder and (y) the Lender assignor thereunder
shall, to the extent that rights 





                                       63
   68



and obligations hereunder have been assigned by it pursuant to such Assignment
and Acceptance, relinquish its rights and be released from its obligations under
this Agreement (and, in the case of an Assignment and Acceptance covering all or
the remaining portion of an assigning Lender's rights and obligations under this
Agreement, such Lender shall cease to be a party hereto, provided, however, such
assigning Lender shall retain any claim with respect to any fee, interest, cost,
expense or indemnity which accrues, or relates to an event that occurs, prior to
the date of such assignment pursuant to Section 2.03, 2.06, 2.07, 2.11, 2.12,
2.15 or 8.04).

          (b) By executing and delivering an Assignment and Acceptance, each
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) other than as provided
in such Assignment and Acceptance, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto; (ii) such assigning Lender makes no representation or warranty and
assumes no responsibility with respect to the financial condition of the
Borrower or the performance or observance by the Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such assignee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Administrative Agent, such assigning Lender or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such assignee confirms that it is (subject to
approval in writing by the Borrower and the Administrative Agent to the extent
required) an Eligible Assignee; (vi) such assignee appoints and authorizes the
Administrative Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Administrative Agent by
the terms hereof, together with such powers as are reasonably incidental
thereto; and (vii) such assignee agrees that it will perform in accordance with
their terms all of the obligations which by the terms of this Agreement are
required to be performed by it as a Lender.

          (c) The Administrative Agent shall maintain at its address referred to
in Section 8.02 a copy of each Assignment and Acceptance, each Designation
Agreement, each New Lender Agreement and each Commitment Increase Agreement
delivered to and accepted by it and a register for the recordation of the 






                                       64
   69



names and addresses of the Lenders and, with respect to Lenders other than
Designated Bidders, the Commitment of, and principal amount of the A Advances
owing to, each Lender from time to time (the "REGISTER"). The entries in the
Register shall be conclusive and binding for all purposes, absent manifest
error, and the Borrower, the Administrative Agent and the Lenders may treat each
Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

          (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note or Notes subject to such assignment, the Administrative
Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit D hereto, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Borrower. Within five Business Days
after its receipt of such notice and its receipt of an executed counterpart of
such Assignment and Acceptance, the Borrower, at its own expense, shall execute
and deliver to the Administrative Agent in exchange for the surrendered Note or
Notes a new Note to the order of such Eligible Assignee and, if the assigning
Lender has retained a Commitment hereunder, a new Note to the order of the
assigning Lender. Such new Note or Notes shall be dated the effective date of
such Assignment and Acceptance and shall otherwise be in substantially the form
of Exhibit A hereto.

          (e) Each Lender (other than a Designated Bidder) may designate one or
more banks or other entities to have a right to make B Advances as a Lender
pursuant to Section 2.19; provided that (i) such Lender shall have obtained the
written consent of the Administrative Agent and the Borrower, such consent not

than two such designations, (iii) each such Lender making one or more of such
designations shall retain the right to make B Advances as a Lender pursuant to
Section 2.19, (iv) each such designation shall be to a Designated Bidder and (v)
the parties to each such designation shall execute and deliver to the
Administrative Agent, for its acceptance and recording in the Register, a
Designation Agreement. Upon such execution, delivery, acceptance and recording,
from and after the effective date specified in each Designation Agreement, the
designee thereunder shall be a party hereto with a right to make B Advances as a
Lender pursuant to Section 2.19 and the obligations related thereto.

          (f) By executing and delivering a Designation Agreement, the Lender
making the designation thereunder and its designee thereunder confirm and agree
with each other and the other parties hereto as follows: (i) such Lender makes
no 




                                       65
   70


representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other instrument or document
furnished pursuant hereto, (ii) such Lender makes no representation or warranty
and assumes no responsibility with respect to the financial condition of the
Borrower or the performance or observance by the Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such designee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into the
Designation Agreement; (iv) such designee will, independently and without
reliance upon the Administrative Agent, such designating Lender or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such designee confirms that it is a Designated
Bidder; (vi) such designee appoints and authorizes the Administrative Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Administrative Agent by the terms hereof,
together with such powers as are reasonably incidental thereto, and (vii) such
designee agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement are required to be performed by
it as a Lender.

          (g) Upon its receipt of a Designation Agreement executed by a
designating Lender and a designee representing that it is a Designated Bidder,
the Administrative Agent shall, if such Designation Agreement has been completed
and is substantially in the form of Exhibit K hereto, (i) accept such
Designation Agreement, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the Borrower.

          (h) Each Lender may sell participations to one or more banks or other
entities in or to all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Commitment, and the Advances owing
to it and the Note or Notes held by it); provided, however, that (i) such
Lender's obligations under this Agreement (including its Commitment to the
Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the holder of any such Note for all purposes of
this Agreement, (iv) the Borrower, the Administrative Agent and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement, (v)
such Lender shall 






                                       66
   71


continue to be able to agree to any modification or amendment of this Agreement
or any waiver hereunder without the consent, approval or vote of any such
participant or group of participants, other than modifications, amendments and
waivers which (A) postpone any date fixed for any payment of, or reduce any
payment of, principal of or interest on such Lender's Note or any facility fees
payable under this Agreement, or (B) increase the amount of such Lender's
Commitment in a manner which would have the effect of increasing the amount of a
participant's participation, or (C) reduce the interest rate payable under this
Agreement and such Lender's Note, or (D) consent to the assignment or the
transfer by the Borrower of any of its rights and obligations under the
Agreement, and (vi) except as contemplated by the immediately preceding clause
(v), no participant shall be deemed to be or to have any of the rights or
obligations of a "Lender" hereunder.

          (i) Any Lender may, in connection with any assignment, designation or
participation or proposed assignment, designation or participation pursuant to
this Section 8.07, disclose to the assignee, designee or participant or proposed
assignee, designee or participant, any information relating to the Borrower
furnished to such Lender by or on behalf of the Borrower; provided that, prior
to any such disclosure, the assignee, designee or participant or proposed
assignee, designee or participant shall agree in writing for the benefit of the
Borrower to preserve the confidentiality of any confidential information
relating to the Borrower received by it from such Lender in a manner consistent
with Section 8.08.

          (j) Anything in this Agreement to the contrary notwithstanding, any
Lender may at any time create a security interest in all or any portion of its
rights under this Agreement (including the Advances owing to it) and the Notes
issued to it hereunder in favor of any Federal Reserve Bank in accordance with
Regulation A of the Board of Governors of the Federal Reserve System (or any
successor regulation) and the applicable operating circular of such Federal
Reserve Bank.

         SECTION 8.8. Confidentiality. Each Lender and the Administrative Agent
(each, a "PARTY") agrees that it will use its best reasonable efforts not to
disclose, without the prior consent of the Borrower (other than to its, or its
Affiliates, employees, auditors, accountants, counsel or other representatives,
whether existing at the date of this Agreement or any subsequent time), any
information with respect to the Borrower which is furnished pursuant to this
Agreement, provided that any party may disclose any such information (i) as has
become generally available to the public, (ii) as may be required or appropriate
in any report, statement or testimony submitted to any municipal, state or
Federal regulatory body having or claiming to have jurisdiction over such party
or to the 




                                       67
   72



Board of Governors of the Federal Reserve System or the Federal Deposit
Insurance Corporation or similar organizations (whether in the United States or
elsewhere) or their successors, (iii) as may be required or appropriate in
response to any summons or subpoena or in connection with any litigation or
regulatory proceeding, (iv) in order to comply with any law, order, regulation
or ruling applicable to such party, or (v) to any prospective assignee, designee
or participant in connection with any contemplated assignment of any rights or
obligations hereunder, any designation or any sale of any participation therein,
by such party pursuant to Section 8.07, if such prospective assignee, designee
or participant, as the case may be, executes an agreement with the Borrower
containing provisions substantially similar to those contained in this Section
8.08; provided, however, that the Borrower acknowledges that the Administrative
Agent has disclosed and may continue to disclose such information as the
Administrative Agent in its sole discretion determines is appropriate to the
Lenders from time to time.

         SECTION 8.9.  Consent to Jurisdiction.

          (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 Administrative 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. Service of the summons and complaint and any other process
which may be served by the Administrative Agent, the Arranger, any Lender or the
holder of any Note on the Borrower in any such action or proceeding in any
aforementioned court in respect of Permitted Claims may be made by delivering
separate copies of such process to the Borrower by courier and by certified mail
(return receipt requested), fees and postage prepaid at the Borrower's address
specified pursuant to Section 8.02, to the attention of each of the Treasurer
and the Executive Vice President, Law. 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 Administrative
Agent to serve legal process in any other manner permitted by law or affect any
right 





                                       68
   73




otherwise existing of the Borrower, any Lender, the Arranger, the holder of any
Note or the Administrative 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.

         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. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.
Delivery to the Administrative Agent of a counterpart executed by a Lender shall
constitute delivery of such counterpart to all of the Lenders.

         SECTION 8.12. WAIVER OF JURY TRIAL. THE BORROWER, THE ADMINISTRATIVE
AGENT, AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY AND ALL
RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT, ANY OF THE NOTES OR ANY OTHER INSTRUMENT OR DOCUMENT FURNISHED
PURSUANT HERETO OR IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

The applicable pricing level shall change on the date of any relevant change in
the rating by S&P or Moody's of any public long term senior unsecured debt
securities of the Borrower. In the case of split ratings from S&P and Moody's,
the rating to be used to determine the applicable pricing level is the higher of
the two (e.g., A-/Baa1 results in Level II pricing), provided that in the event
the split is more than one full category, the average (or the higher of two
intermediate ratings) shall be used (e.g., A-/Baa2 results in Level III pricing,
as does A-/Baa3).

                  Lender to increase that Lender's Commitment.

         B.       The Borrower has given notice to the Administrative Agent of
                  its intention to increase the total Commitments pursuant to
                  such Section 2.20 by increasing the Commitment of the
                  Increasing Lender from $_______ to $________, and the
                  Administrative Agent is willing to consent thereto.

Accordingly, the parties hereto agree as follows:

         SECTION 1. Increase of Commitment. Pursuant to Section 2.20 of the
Credit Agreement, the Commitment of the Increasing Lender is hereby increased
from $________ to $__________.

         SECTION 2. Consent. The Administrative Agent hereby consents to the
increase in the Commitment of the Increasing Lender effectuated hereby.

         SECTION 3. Governing Law. This Agreement shall be governed by, and
construed in accordance with the laws of the State of New York.

         SECTION 4. Execution in Counterparts. This Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.



   97



         SECTION 5. Lender Credit Decision. The Increasing Lender acknowledges
that it has, independently and without reliance upon the Administrative 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 and to agree
to the various matters set forth herein. The Increasing Lender also acknowledges
that it will, independently and without reliance upon the Administrative Agent
or any other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under the Credit Agreement.

         SECTION 6. Representations and Warranties of the Borrower. The

terminated, the Borrower has caused, or is simultaneously causing, the

Directors of the Borrower sufficient to authorize this Agreement, and such

                                     FORM OF
               OPINION OF SENIOR VICE PRESIDENT, LAW FOR BORROWER



February ____, 1998


To each of the Lenders and the Agents
  Referred to Below
c/o Morgan Guaranty Trust Company of New York
60 Wall Street, 22nd Floor
New York, New York  10260


Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 3.01(d) of the Long-Term
Revolving Credit Agreement, dated as of February 25, 1998 (the "Credit
Agreement"), among Burlington Resources Inc., a Delaware corporation (the
"Borrower"), the financial institutions party thereto (each a "Lender," and
together the "Lenders"), Morgan Guaranty Trust Company of New York, as
Administrative Agent for the Lenders, Citibank, N.A., as Syndication Agent, and
Chase Bank of Texas, N.A. and NationsBank of Texas, N.A., as Co-Documentation
Agents. Unless the context otherwise requires, all capitalized terms used herein
without definition shall have the meanings ascribed to them in the Credit
Agreement.

I am Senior Vice President, Law of the Borrower, and I, or attorneys over whom I
exercise supervision, have acted as counsel for the Borrower in connection with
the preparation, execution and delivery of the Credit Agreement. In that
connection, I or such attorneys have examined:

                (1)      The Credit Agreement, executed by the parties thereto;

                (2)      The Notes executed by the Borrower; and

                (3)      The other documents furnished by the Borrower pursuant 
                         to Section 3.01 of the Credit Agreement.

I, or attorneys over whom I exercise supervision, have also examined the
originals, or copies certified to our satisfaction, of the agreements,
instruments and other documents, and all of the orders, writs, judgments,
awards, injunctions and decrees, which affect or purport to affect the






   102



Borrower's ability to perform the Borrower's obligations under the Credit
Agreement or the Notes (collectively referred to herein as the "Documents"). In
addition, I, or attorneys over whom I exercise supervision, have examined the
originals, or copies certified to our satisfaction, of such other corporate
records of the Borrower, certificates of public officials and of officers of the
Borrower, and agreements, instruments and other documents, as I have deemed
necessary as a basis for the opinions hereinafter expressed. In all such
examinations, I, or attorneys over whom I exercise supervision, have assumed the
legal capacity of all natural persons executing documents, the genuineness of
all signatures on original or certified, conformed or reproduction copies of
documents of all parties (other than, with respect to the Documents, the
Borrower), the authenticity of original and certified documents and the
conformity to original or certified copies of all copies submitted to such
attorneys or me as conformed or reproduction copies. As to various questions of
fact relevant to the opinions expressed herein, I have relied upon, and assume
the accuracy of, representations and warranties contained in the Credit
Agreement and certificates and oral or written statements and other information
of or from public officials, officers and/or representatives of the Borrower and
others.

To the extent it may be relevant to the opinions expressed herein, I have
assumed that the parties to the Documents other than the Borrower have the power
to enter into and perform such documents and that such documents have been duly
authorized, executed and delivered by, and constitute legal, valid and binding
obligations of, such parties.

The opinions expressed below are limited to the federal laws of the United
States and, to the extent relevant hereto, the General Corporation Law of the
State of Delaware, as currently in effect. I assume no obligation to supplement
this opinion if any applicable laws change after the date hereof or if I become
aware of any facts that might change the opinions expressed herein after the
date hereof.

Based upon the foregoing and upon such investigation as I have deemed necessary,
and subject to the limitations, qualifications and assumptions set forth herein,
I am of the following opinion:

     1.  The Borrower (i) is a corporation duly incorporated and existing in
         good standing under the laws of the State of Delaware, and (ii)
         possesses all the corporate powers and all other authorizations and
         licenses necessary to engage in its business and operations as now
         conducted, the failure to obtain or maintain which would have a
         Material Adverse Effect.

     2.  The execution, delivery and performance by the Borrower of the
         Documents are within the Borrower's corporate powers and have been duly
         authorized by all necessary corporate action in respect of or by the
         Borrower (except to the extent that the Borrower seeks to exercise its
         right under Section 2.20 of the Credit Agreement to effect an increase
         of Commitments), and do not contravene (i) the Borrower's Certificate
         of Incorporation or By-Laws, in each case as amended, (ii) any federal
         law, rule or regulation applicable to the Borrower (excluding
         provisions of federal law expressly referred to in and covered by the
         opinion of Jones, Day, Reavis & Pogue delivered to you in connection
         with the transactions 






   103

         contemplated hereby), or (iii) any contractual restriction binding on 
         or affecting the Borrower. The Documents have been duly executed and
         delivered on behalf of the Borrower.

     3.  No authorization or approval or other action by, and no notice to or
         filing with, any federal governmental authority or regulatory body
         (including, without limitation, the Federal Energy Regulatory
         Commission) is required for the due execution, delivery and performance
         by the Borrower of the Documents, except those required in the ordinary
         course of business in connection with the performance by the Borrower
         of its obligations under certain covenants and warranties contained in
         the Documents.

     4.  To the best of my knowledge, there is no action, suit or proceeding
         pending or overtly threatened against or involving the Borrower or any
         of its Material Subsidiaries, which, in my reasonable judgment (taking
         into account the exhaustion of all appeals), would have a material
         adverse effect upon the consolidated financial condition of the
         Borrower and its consolidated Subsidiaries taken as a whole, or which
         purports to affect the legality, validity, binding effect or
         enforceability of any Document.

These opinions are given as of the date hereof and are solely for your benefit
in connection with the transactions contemplated by the Credit Agreement. These
opinions may not be relied upon by you for any other purpose or relied upon by
any other person for any purpose without my prior written consent.


Very truly yours,



L. David Hanower
Senior Vice President, Law

                              COUNSEL FOR BORROWER

                                                               February __, 1998

To Each of the Lenders and the Administrative Agent
  Referred to Below
c/o Morgan Guaranty Trust Company of New York
60 Wall Street, 22nd Floor
New York, New York 10260

      Re:   Long-Term Revolving Credit Agreement, dated as of February 25, 1998

Ladies and Gentlemen:

         We have acted as special New York counsel for Burlington Resources
Inc., a Delaware corporation (the "Borrower"), in connection with the Long-Term
Revolving Credit Agreement, dated as of February __, 1998 (the "Credit
Agreement"), among the Borrower, the financial institutions party thereto (each
a "Lender," and together the "Lenders"), and Morgan Guaranty Trust Company of
New York, as Administrative Agent for the Lenders, Citibank, N.A., as
Syndication Agent for the Lenders, and Chase Bank of Texas, N.A. and NationsBank
of Texas, N.A., as Co-Documentation Agents for the Lenders. This opinion is
delivered to you pursuant to Section 3.01(e) of the Credit Agreement. All
capitalized terms used herein that are defined in, or by reference in, the
Credit Agreement have the meanings assigned to such terms therein, or by
reference therein, unless otherwise defined herein. With your permission, all
assumptions and statements of reliance herein have been made without any
independent investigation or verification on our part except to the extent
otherwise expressly stated, and we express no opinion with respect to the
subject matter or accuracy of such assumptions or items relied upon.

         In connection with this opinion, we have (i) investigated such
questions of law, (ii) examined originals or certified, conformed or
reproduction copies of such documents, and (iii) received such information from
officers and representatives of the Borrower as we have deemed necessary or
appropriate for the purposes of this opinion. We have examined, among other
documents, the following:

         (a) A facsimile of an executed copy of the Credit Agreement;

         (b) A facsimile of an executed copy of each of the __ Notes; and

         (c) A facsimile of the Officer's Certificate of the Borrower delivered
             to us in connection with this opinion, a copy of which is attached 
             hereto as Annex A.



   105



The documents referred to in items (a) and (b) above are referred to herein
collectively as the "Documents."

         In all such examinations, we have assumed the legal capacity of all
natural persons executing documents, the genuineness of all signatures, the
authenticity of original and certified documents and the conformity to original
or certified copies of all copies submitted to us as conformed or reproduction
copies. As to various questions of fact relevant to the opinions expressed
herein, we have relied upon, and assume the accuracy of, representations and
warranties contained in the Documents and certificates and oral or written
statements and other information of or from representatives of the Borrower and
others. With respect to the opinions expressed in paragraph (a) below, our
opinions are limited (x) to our actual knowledge of the Borrower's specially
regulated business activities and properties based solely upon an officer's
certificate in respect of such matters and without any independent investigation
or verification on our part and (y) to our review of only those laws and
regulations that, in our experience, are normally applicable to transactions of
the type contemplated by the Documents.

         To the extent it may be relevant to the opinions expressed herein, we
have assumed that the parties to the Documents other than the Borrower have the
power to enter into and perform such documents and that such documents have been
duly authorized, executed and delivered by, and constitute legal, valid and
binding obligations of, such parties.

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

         (a) The execution and delivery to the Administrative Agent and the
Lenders by the Borrower of the Documents and the performance by the Borrower of
its obligations thereunder (i) do not require under present law any filing or
registration by the Borrower with, or approval or consent to the Borrower of,
any governmental agency or authority of the State of New York, except those, if
any, required in the ordinary course of business in connection with the
performance by the Borrower of its obligations under certain covenants and
warranties contained in the Documents and (ii) do not violate any present law,
or present regulation of any governmental agency or authority, of the State of
New York applicable to the Borrower or its property.

         (b) The Documents constitute the legal, valid and binding obligations
of the Borrower enforceable against the Borrower in accordance with their
respective terms.

         (c) The borrowings by the Borrower under the Credit Agreement and the
applications of the proceeds thereof as provided in the Credit Agreement will
not violate Regulation G, T, U or X of the Board of Governors of the Federal
Reserve System.

         The opinions set forth above are subject to the following
qualifications:

         (A) We express no opinion as to:



   106



                      (i) the validity, binding effect or enforceability (a) of
         any provision of the Documents relating to indemnification,
         contribution or exculpation in connection with violations of any
         securities laws or statutory duties or public policy, or in connection
         with willful, reckless or criminal acts or gross negligence of the
         indemnified or exculpated party or the party receiving contribution; or
         (b) of any provision of any of the Documents relating to exculpation of
         any party in connection with its own negligence that a court would
         determine in the circumstances under applicable law to be unfair or
         insufficiently explicit;

                      (ii) the validity, binding effect or enforceability of (a)
         any purported waiver, release, variation, disclaimer, consent or other
         agreement to similar effect (all of the foregoing, collectively, a
         "Waiver") by the Borrower under the Documents to the extent limited by
         provisions of applicable law (including judicial decisions), or to the
         extent that such a Waiver applies to a right, claim, duty, defense or
         ground for discharge otherwise existing or occurring as a matter of law
         (including judicial decisions), except to the extent that such a Waiver
         is effective under and is not prohibited by or void or invalid under
         provisions of applicable law (including judicial decisions) or (b) any
         provision of any Document relating to choice of governing law to the
         extent that the validity, binding effect or enforceability of any such
         provision is to be determined by any court other than a court of the
         State of New York;

                      (iii) the enforceability of any provision in the Documents
         specifying that provisions thereof may be waived only in writing, to
         the extent that an oral agreement or an implied agreement by trade
         practice or course of conduct has been created that modifies any
         provision of the Documents;

                      (iv) the effect of any law of any jurisdiction other than
         the State of New York wherein the Administrative Agent or any Lender
         may be located or wherein enforcement of any document referred to above
         may be sought that limits the rates of interest legally chargeable or
         collectible; and

                      (v) any approval, consent or authorization of the Federal
         Energy Regulatory Commission or any other United States federal agency
         or authority needed in connection with the execution, delivery and
         performance by the Borrower of the Documents, the consummation of the
         transactions contemplated thereby and compliance with the terms and
         conditions thereof.

         (B) Our opinions above are subject to (i) applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or similar laws from
time to time in effect affecting creditors' rights generally, (ii) general
principles of equity (including, without limitation, standards of materiality,
good faith, fair dealing and reasonableness), whether such principles are
considered in a proceeding at law or in equity and (iii) the qualification that
certain other provisions of the Documents may be unenforceable in whole or in
part under the laws (including judicial decisions) of the State of New York or
the United States of America, but the 




   107



inclusion of such provisions does not affect the validity as against the
Borrower of the Documents as a whole, and the Documents contain adequate
provisions for enforcing payment of the obligations governed thereby, subject to
the other qualifications contained in this letter.

         (C) For purposes of the opinions set forth in paragraph (c) above, we
have assumed that (i) neither the Administrative Agent nor any of the Lenders
has or will have the benefit of any agreement or arrangement (excluding the
Documents) pursuant to which any Advances are directly or indirectly secured by
Margin Stock, (ii) neither the Administrative Agent nor any of the Lenders nor
any of their respective affiliates has extended or will extend any other credit
to the Borrower directly or indirectly secured by Margin Stock and (iii) neither
the Administrative Agent nor any of the Lenders has relied or will rely upon any
Margin Stock as collateral in extending or maintaining any Advances pursuant to
the Credit Agreement.

         (D) For purposes of our opinions above, insofar as they relate to the
Borrower, we have assumed that (i) the Borrower is a corporation validly
existing in good standing in its jurisdiction of incorporation, has all
requisite power and authority, and has obtained all requisite corporate,
shareholder, third party and governmental authorizations, consents and
approvals, and made all requisite filings and registrations, necessary to
execute, deliver and perform the Documents (except to the extent noted in
paragraph (a) above), and that such execution, delivery and performance will not
violate or conflict with any law, rule, regulation, order, decree, judgment,
instrument or agreement binding upon or applicable to the Borrower or its
properties (except to the extent noted in paragraph (a) above), and (ii) the
Documents have been duly executed and delivered by the Borrower.

         We express no opinion as to the effect of the compliance or
noncompliance of each of the addressees with any state or federal laws or
regulations applicable to each of them by reason of their status as or
affiliation with a federally insured depository institution, except as expressly
set forth in paragraph (c) above.

         The opinions expressed herein are limited to the federal laws of the
United States of America (in the case of the matters covered in paragraph (c)
above) and the laws of the State of New York (in the case of the matters covered
in paragraphs (a) and (b) above), as currently in effect.

         The opinions expressed herein are solely for the benefit of the
Administrative Agent and the Lenders and may not be relied on in any manner or
for any purpose by any other person or entity.

                                         Very truly yours,

To the Lenders and the Agents
  Referred to Below
c/o Morgan Guaranty Trust Company
  of New York, as Administrative Agent
  60 Wall Street
  New York, New York 10260

Ladies and Gentlemen:

         We have participated in the preparation of the Long-Term Credit
Agreement dated as of February 25, 1998 (the "CREDIT AGREEMENT") among
Burlington Resources Inc., a Delaware corporation (the "BORROWER"), the Lenders
party thereto, Morgan Guaranty Trust Company of New York, as Administrative
Agent, Citibank, N.A., as Syndication Agent and Chase Bank of Texas, N.A. and
NationsBank of Texas, N.A. as Co-Documentation Agents and have acted as special
counsel for the Administrative Agent for the purpose of rendering this opinion
pursuant to Section 3.01(f) of the Credit Agreement. Terms defined in the Credit
Agreement are used herein as therein defined.

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such documents, corporate records, certificates of
public officials and other instruments and have conducted such other
investigations of fact and law as we have deemed necessary or advisable for
purposes of this opinion.

         Upon the basis of the foregoing, we are of the opinion that:

         1. The execution, delivery and performance by the Borrower of the
Credit Agreement and the Notes are within the Borrower's corporate powers and
have been duly authorized by all necessary corporate action.

         2. The Credit Agreement constitutes a valid and binding agreement of
the Borrower and each Note issued thereunder today constitutes a valid and
binding obligation of the Borrower, in each case enforceable in accordance with
its terms, subject to applicable bankruptcy, insolvency or similar laws
affecting creditors' rights generally and general principles of equity. 





   109



         We are members of the Bar of the State of New York and the foregoing
opinion is limited to the laws of the State of New York, the federal laws of the
United States of America and the General Corporation Law of the State of
Delaware. In giving the foregoing opinion, we express no opinion as to the
effect (if any) of any law of any jurisdiction (except the State of New York) in
which any Lender is located which limits the rate of interest that such Lender
may charge or collect.

         This opinion is rendered solely to you in connection with the above
matter. This opinion may not be relied upon by you for any other purpose or
relied upon by any other Person without our prior written consent.

                                         Very truly yours,

                           in respect of the LONG-TERM CREDIT AGREEMENT dated as
                           of February 25, 1998 (the "Credit Agreement"), among
                           BURLINGTON RESOURCES INC., a Delaware corporation

                           Morgan Guaranty Trust Company of New York, as
                           administrative agent (in such capacity, the "Original
                           Administrative Agent") for the Lenders hereunder,
                           Citibank, N.A., as syndication agent for the Lenders,

         Agreement and the Exhibits to agents, to the Credit Agreement and to

         this Amendment and Restatement and the Short-Term Amendment and
         Restatement.

represents and warrants as of the effective date of this Amendment and
Restatement to each of the Lenders that:

                  (a) Before and after giving effect to this Amendment and

         effect as if made on the effective date hereof, except to the extent
         such representations and warranties expressly relate to an earlier
         date.

                  (b) Immediately before and after giving effect to this
