                 This Amendment No. 2 to the Tender Offer Statement on Schedule
14D-1 dated June 23, 1997 and Amendment No. 1 to the Schedule 13D dated June 27,
1997, relating to the offer by Monterey Acquisition Corporation, a Delaware
corporation (the "Purchaser") and a wholly owned subsidiary of Monterey
Resources, Inc., a Delaware corporation ("Monterey"), to purchase all
outstanding shares of common stock, par value $1.00 per share (the "Shares"), of
McFarland Energy, Inc. (the "Company"), amends and supplements such Schedule 
14D-1 and Schedule 13D as follows:


ITEM 4 -- SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION (Schedule 14D-1)

ITEM 3 -- SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION (Schedule 13D) 

                 Item 4 of the Schedule 14D-1 and Item 3 of the Schedule 13D are
hereby amended in their entirety to read as follows:

                          The total amount of funds required by the Purchaser to
                 purchase all outstanding Shares is estimated to be
                 approximately $111.4 million.  The funds necessary to purchase
                 Shares pursuant to the Offer and to pay related fees and
                 expenses was furnished to the Purchaser (i) by Monterey as a
                 capital contribution and (ii) through the financing described
                 below.

                         Monterey, The Chase Manhattan Bank ("Chase"), as the
                 administrative agent and as lender, and four other lenders
                 were parties to a five-year revolving credit facility, entered
                 into in November 1996, providing for aggregate extensions of
                 credit thereunder to Monterey of $75 million (the "Old
                 Facility").  On July 22, 1997 (1) with the consent of Chase
                 and the other lenders, Monterey terminated the Old Facility,
                 (2) Chase, as administrative agent and as lender, Union Bank
                 of Switzerland (Houston Agency) ("UBS"), as co-arranger and as
                 lender, and Monterey entered into a Credit Agreement providing
                 for aggregate extensions of credit to Monterey of up to $200
                 million, with a final maturity in July,  2002 (the "New
                 Facility"), and (3) Monterey borrowed from Chase and UBS the
                 aggregate sum of  $100 million under the New Facility and
                 placed under the New Facility certain existing letters of
                 credit originally issued under the Old Facility.  Chase and
                 UBS propose to syndicate the New Facility to other lenders,
                 but Monterey expects that each will retain a significant
                 portion of the credit.

                         Loans under the New Facility will bear interest, at
                 Monterey's election, at rates calculated by adding an agreed
                 margin to Chase's prime rate or the federal funds effective
                 rate, or the applicable LIBOR rate for interest periods of
                 one, two, three or six months.  As was the case with the Old
                 Facility, applicable interest rate margins are to be
                 established from time to time by reference to Monterey's
                 historical ratios of outstanding indebtedness to its EBITDA,
                 as defined in the Credit Agreement, as adjusted to reflect
                 certain Restricted Payments (as so defined).  As did the Old
                 Facility, the New Facility makes provision for issuance of
                 letters of credit, with an availability sublimit of $50
                 million. Overall availability of credit under the New Facility
                 from time to time will be a function of Available Borrowing
                 Base (initially to be defined as $200 million). The Available
                 Borrowing Base will be redetermined by Chase, as
                 administrative agent, from time to time as a function of the
                 total amount of indebtedness that can be supported by the
                 proved oil and gas reserves of Monterey and its Restricted
                 Subsidiaries, based upon periodic independent engineering
                 reports, minus their Other Liabilities.  Such Other
                 Liabilities are defined as liabilities in respect of certain
                 outstanding indebtedness (which would include, without
                 limitation, for so long as the same shall remain outstanding,
                 Monterey's 10.61% Senior Notes due March

                 31, 2005, originally issued and currently outstanding in the
                 aggregate principal amount of $175 million, but would exclude
                 certain indebtedness subordinated to Monterey's obligations to
                 the lenders under the New Facility on agreed terms, and
                 subject to other terms, including covenants and defaults, no
                 more restrictive than the terms of the New Facility and to
                 certain requirements as to final maturity and weighted average
                 life), and letter of credit obligations, in each case incurred
                 outside of the New Facility. The Credit Agreement relating to
                 the New Facility contains representations and warranties,
                 affirmative and negative covenants (including requirements to
                 maintain certain financial ratios and limitations upon debt
                 incurrence, liens, asset sales, restricted payments and
                 investments, affiliate transactions, mergers, sale and
                 leaseback transactions and certain activities of Restricted
                 Subsidiaries), binding upon Monterey and its Restricted
                 Subsidiaries, and events of default, similar to those
                 contained in the Old Facility.

ITEM 6 -- INTEREST IN SECURITIES OF THE SUBJECT COMPANY (Schedule 14D-1)

ITEM 5 -- INTEREST IN SECURITIES OF THE ISSUER (Schedule 13D)

                 Item 6 of the Schedule 14D-1 and Item 5 of the Schedule 13D are
hereby amended by adding the following information thereto:

                 Based on the final count of Shares validly tendered and not
                 properly withdrawn pursuant to the Offer, Monterey purchased
                 5,548,846 Shares, which represented approximately 96.9% of
                 Shares outstanding. On July 24, 1997, Monterey caused a merger
                 of Monterey Acquisition Corporation with and into McFarland in
                 accordance with Section 253 of the Delaware General 
                 Corporation Law.


ITEM 11 -- MATERIAL TO BE FILED AS EXHIBITS (Schedule 14D-1)

                 Item 11 of the Schedule 14D-1 is hereby amended and 
supplemented by the addition of the following, which are attached hereto as

Bakersfield, California--July 22, 1997

Monterey Resources (NYSE:  MRC) today announced the successful completion of
the tender offer by Monterey Acquisition Corporation, a Delaware corporation
wholly owned by Monterey Resources, to purchase all the outstanding shares of
common stock of McFarland Energy (NASDAQ:  MCFE), a Delaware corporation.  As
of 12:00 midnight EDT, on Monday, July 21, 1997, the deadline for tendering
shares, an aggregate of 5,548,846 shares of common stock of McFarland were
validly tendered, of which an aggregate of 37,604 had been tendered pursuant to
notice of guaranteed delivery procedures.  The tendered shares represent
approximately 96.9% of the total outstanding shares of common stock of
McFarland.  Accordingly, the minimum share condition, which required that the
tendered shares constitute not less than a majority of the shares of McFarland
on a fully diluted basis, has been satisfied.

Monterey Resources also announced that as of 12:00 midnight EDT, on Monday,
July 21, 1997, the tender offer expired and was terminated and that the
tendered shares will be accepted by it for payment of $18.55 per share, net to
the seller in cash, without interest thereon.  Following the acceptance of the
tendered shares, approximately 178,576 of the outstanding shares will be owned
by persons other than Monterey Resources and Monterey Acquisition Corporation.

In view of the magnitude of the response, Monterey Resources will now cause a
short-form merger of Monterey Acquisition Corporation with and into McFarland
to be effected in accordance with Section 253 of the Delaware General
Corporation Law.  Pursuant to that short-form merger, shares not purchased in
the offer will be converted into the right to receive $18.55 in cash, without
interest thereon.  It is currently anticipated that such short-form merger will
occur on or about July 24, 1997.  Holders of those shares of common stock which
were not tendered prior to the expiration of the tender offer will receive
notice that the merger has occurred and will have the opportunity to exercise
appraisal rights if such holders follow the procedures under Delaware law.

Monterey Resources in an independent oil and gas company engaged in the
production, development and acquisition of oil and natural gas in the State of
California.  The Company conducted its operations as the Western Division of
Santa Fe Energy Resources (NYSE:  SFR) until the November 1996 IPO of its
common stock.  SFR currently owns approximately 83 percent of the outstanding
shares of MRC and will spin off those shares in a tax-free distribution to SFR
shareholders on July 25, 1997.  The common stock of Monterey Resources is
traded on the New York Stock Exchange under the symbol MRC.

among MONTEREY RESOURCES, INC. (the "Company"), a Delaware corporation; each of

Agent for the Banks (in such capacity, together with any other Person who
becomes the Agent pursuant to Section 11.8, the "Agent") and UNION BANK OF
SWITZERLAND, as Co-Arranger (in such capacity, the "Co-Arranger").

Agreements.

         The parties agree as follows:

         Section 1.       Definitions and Accounting Matters.

Credit Documents,  the following terms shall have the following meanings:

         "Acquisition" shall mean the transaction by which the Company becomes
the owner of more than 50% of the outstanding capital stock of McFarland.

         "Additional Costs" shall have the meaning ascribed to such term in
Section 6.1.

         "Adjusted EBITDA" shall mean, for any period, EBITDA for such period
minus the aggregate of all Restricted Payments made by the Company and the
Restricted Subsidiaries in such period.

control with" shall mean the possession, directly or indirectly, of power to
direct or cause the direction of the management or policies (whether through

         "Agreement" shall have the meaning ascribed to such term in the
introduction.

         "Alternate Base Rate" shall mean, for any day, a rate per annum
(rounded upwards, if necessary, to the next higher 1/100%) equal to the greater

the Agent shall have determined (which determination shall be conclusive absent
manifest error) that it is unable to ascertain the Fed Funds Rate for any
reason, including the inability or failure of the Agent to obtain sufficient

Rate shall be the Prime Rate until the circumstances giving rise to such

toxicity of the aforesaid, including, without limitation, the Resource
Conservation and Recovery Act of 1976, The Comprehensive Environmental
Response, Compensation and Liability Act of 1980 (as amended by the Superfund
Amendments and Reauthorization Act), the Emergency Planning and Community
Right-to-Know Act, the Toxic Substances Control Act, the Solid Waste Disposal
Act, the Safe Drinking Water Act, the Hazardous Materials Transportation Act,
the Clean Air Act, the Clean Water Act, the Oil Pollution Act, and the Federal
Insecticide, Fungicide and Rodenticide Act, in each case as amended from time
to time.

         "Applicable Lending Office" shall mean, for each Bank and for each
Type of Loan, the lending office of such Bank (or of an Affiliate of such Bank)
designated for such Type of Loan below its name on the signature pages hereof
or such other office of such Bank (or of an Affiliate of such Bank) as such

by which its Loans of such Type are to be made and/or issued and maintained.

generally accepted financial practice) of at least six and one half years from
the date of issuance thereof, (ii) subject to terms (including covenants and
events of default) no more restrictive with respect to the issuer thereof (as
determined by the Agent in its sole discretion) than the terms of this
Agreement, and (iii) which is made subordinate and junior to the Obligations by

Notes, all security therefor and guaranties thereof and all restrictions,
provisions for repayment or acceleration and all other covenants, warranties,
representations and agreements contained in the Credit Documents with respect
to the Notes shall apply to each Letter of Credit Advance.

         Upon the date of the issuance of a Letter of Credit, and on the date
of this Agreement with respect to each Existing Letter of Credit, the Issuer
shall be deemed, without further action by any party to this Agreement, to have
sold to each Bank, and each Bank shall be deemed, without further action by any
party to this Agreement, to have purchased from the Issuer, a participation, to
the extent of such Bank's Commitment Percentage, in such Letter of Credit
(including the Existing Letters of Credit) and the related Letter of Credit
Liabilities.  Any Letter of Credit with an expiry date after the Termination
Date shall be fully Covered or shall be backed by a letter of credit in Proper
Form issued by an issuer acceptable to the Issuer in its sole discretion.

         (b)     The following additional provisions shall apply to each Letter

Company shall give the Agent at least three Business Days' irrevocable prior
notice (effective upon receipt) specifying the date such Letter of Credit is to

such additional information regarding such transaction as the Agent may
reasonably request.  Upon receipt of such notice the Agent shall promptly
notify each Bank of the contents thereof and of such Bank's Commitment
Percentage of the amount of such proposed Letter of Credit.

                 (2)      On each day during the period commencing with the
issuance of any Letter of Credit (or, with respect to each Existing Letter of
Credit commencing with the date of this Agreement) and until such Letter of
Credit shall have expired or been terminated, the Commitment of each Bank shall
be deemed to be utilized for all purposes of this Agreement in an amount equal
to such Bank's Commitment Percentage of the sum of (i) the undrawn amount of
such Letter of Credit plus (ii) the unpaid amount of all Letter of Credit
Advances with respect to such Letter of Credit.

                 (3)      Upon receipt from the beneficiary of any Letter of
Credit of any demand for payment thereunder, the Issuer shall promptly notify
the Company and each Bank as to the amount to be paid as a result of such
demand and the payment date.  If at any time the Issuer shall have made a
payment to a beneficiary of a Letter of Credit in respect of a drawing or in
respect of an acceptance created in connection with a drawing under such Letter
of Credit, each Bank will pay to the Agent immediately upon demand by the Agent
at any time during the period commencing after such payment until reimbursement
thereof in full by the Company, an amount equal to such Bank's Commitment
Percentage of such payment, together with interest on such amount for each day
from the date of demand for such payment (or, if such demand is made after
12:00 noon on such date,





                                       29

such day.

                 (4)      The Company shall be irrevocably and unconditionally
obligated forthwith to reimburse the Issuer for the account of each Bank for
any amount paid by it upon any drawing under any Letter of Credit, without
presentment, demand, protest or other formalities of any kind, all of which are
hereby expressly WAIVED by the Company to the extent not prohibited by law.
Such reimbursement may, subject to satisfaction of the conditions in Section 7
and to the existence of sufficient Available Borrowing Base (after adjustment
in the same to reflect the elimination of the corresponding Letter of Credit
Liability) be made by borrowing of Loans.  The Issuer will pay to each Bank
such Bank's Commitment Percentage of all amounts received from the Company for
application in payment, in whole or in part, of the Reimbursement Obligation in
respect of any Letter of Credit, but only to the extent such Bank has made
payment to the Issuer in respect of such Letter of Credit pursuant to clause
(3) above.

                 (5)      The Company will pay to the Agent at the Principal
Office for the account of each Bank the Letter of Credit Fee on such Bank's
Commitment Percentage of the amount available for drawings under each Letter of
Credit, in each case for the period from and including the date of issuance of
each such Letter of Credit (or, in the case of Existing Letters of Credit, from
the date of this Agreement) to and including the date of expiration or
termination thereof, such Letter of Credit Fees to be paid in arrears on the
Quarterly Dates and on the Termination Date.  The Agent will pay to each Bank,
promptly after receiving any payment in respect of Letter of Credit Fees
referred to in this clause (5), an amount equal to such Bank's Commitment
Percentage of such Letter of Credit Fee. The aggregate Letter of Credit Fee for
any Letter of Credit is subject to a minimum of $600 per annum.

                 (6)      The Company shall pay to the Agent for the account of
the Issuer, in arrears on each Quarterly Date and on the Termination Date, a
fronting fee for each Letter of Credit equal to 1/8 of 1% per annum times the
face amount of such Letter of Credit, in each case for the period from and
including the date of issuance of such Letter of Credit to and including the
date of expiration or termination thereof.

         (c)     Each Letter of Credit shall be subject to the Uniform Customs
and Practice for Documentary Credits (1993 Revision), International Chamber of
Commerce Publication No. 500 (and any subsequent revision thereof approved by a
Congress of the International Chamber of Commerce) and, to the extent not
inconsistent therewith, the laws of the State of New York.

         (d)     To the extent that any provision of any Application is
contrary to or inconsistent with the provisions of this Agreement, the
provisions of this Agreement shall control.

debt (other than Approved Subordinated Debt) issued since the date of the then
most recent determination of the Borrowing Base, exceeds $200,000,000 in

writing of the amount of the Borrowing Base.  Such Borrowing Base shall be the
Borrowing Base from the date of such notification until the date of the next

determination of the Borrowing Base shall be made by the Agent (subject to the
approval of the Required Banks) in its sole discretion using its normal and

Report furnished by the Company.

would cause the aggregate net proceeds of all such Asset Sales of Petroleum
Properties since the effective date of the last calculation of the Borrowing
Base to exceed $20,000,000, the Agent  may, and shall at the request of the
Required Banks, redetermine the Borrowing Base in accordance with the
procedures described in this Agreement on the basis of the information with
respect to the remaining Petroleum Properties set forth in the Most Recent
Engineering Report and, if current, the most recent Company Report.  The
Company shall provide the Agent with all such information as the Agent may
reasonably request and shall otherwise cooperate in good faith with and assist
the Agent and the Required Banks in any such determination.

         (c)     The initial Available Borrowing Base shall be $200,000,000.
Upon each incurrence of an Other Liability which, together with all other Other
Liabilities incurred since the most recent determination of the Available
Borrowing Base, exceeds $10,000,000, and upon each determination of the
Borrowing Base, the Agent shall redetermine the Available Borrowing Base.

         (d)     In addition to the determinations of the Borrowing Base
provided for elsewhere in this Section 2.3, each of the Company or the Required
Banks may, in their sole discretion, require the Agent to determine the
Borrowing Base one additional time in each 12-month period.  Such additional
determination shall be in accordance with the procedures described in this
Agreement on the basis of the information with respect to the Petroleum
Properties at the time of such determination set forth in (at the option of the
Person requiring the determination) a new Independent Engineering Report or the
Most Recent Engineering Report and, if current, the most recent Company Report.
The Company shall provide the Agent with all such information as the Agent may
reasonably request and shall otherwise cooperate in good faith with and assist
the Agent and the Required Banks in any such redetermination.

         2.4     Borrowing Base Deficiencies.   Should there exist at any time
a Borrowing Base Deficiency (other than, except to the extent provided in
Section 3.2(b)(2), a Borrowing Base Deficiency resulting in whole or in part

                                       31
<PAGE>   37
which are addressed in Section 3.2(b)(2)), the Agent may, but shall not be
obligated to (unless requested to do so by the Required Banks), notify the
Company in writing of such deficiency.  Within 90 days after the receipt of
such notice, the Company shall make a prepayment on the Loans or take such
other steps as may be approved by the Agent, or a combination thereof, so that
such Borrowing Base Deficiency is reduced by at least 50%.  Within 180 days
after the giving of such notice, the Company shall make a prepayment on the
Loans or take such other steps as may be approved by the Agent, or a
combination thereof, so that the entire Borrowing Base Deficiency is
eliminated.

         2.5.    Terminations, Reductions and Changes of Commitments.

         (a)     On the Termination Date, all Commitments shall be terminated
in their entirety.

         (b)     The Company shall have the right to terminate or reduce the
unused portion of the Aggregate Commitment at any time or from time to time;
provided that (i) the Company shall give notice of each such termination or
reduction to the Agent as provided in Section 5.5; (ii) each such partial
reduction shall be in an integral multiple of $5,000,000, and (iii) the Company
may not cause the Aggregate Commitment to be less than the aggregate principal
amount of the Loans and Letter of Credit Liabilities then outstanding (after
giving effect to any concurrent repayment of the Loans and reduction of Letter
of Credit Liabilities).

         (c)     No reduction in or termination of the Aggregate Commitment
pursuant to this Section 2.5 may be reinstated without the written approval of
the Agent and all Banks.

         2.6.    Fees.  In consideration of the Commitments, the Company shall
pay to the Agent for the account of each Bank in accordance with its Commitment
Percentage commitment fees (the "Commitment Fees") (a) for each Margin Period
from the date of this Agreement to and including the date such Bank's
Commitment is terminated at a rate per annum for such Margin Period determined
in accordance with the Pricing Schedule and (b) if no Margin Period is in
effect, the rate set forth for commitment fees in Level V of the Pricing
Schedule.  The Commitment Fees shall be computed for each day and shall be
based on such Bank's Commitment Percentage of the Unused Commitment for such
day.  Accrued Commitment Fees shall be due in arrears on the date of the
initial Loans, within three days after demand therefor on or about the
Quarterly Dates, and within three days after demand therefor on or about the
Termination Date.  Upon receipt, the Agent shall disburse such fees to the
Banks in accordance with their respective Commitment Percentages.  All past due
Commitment Fees shall bear interest at the Post-Default Rate.

         2.7.    Affiliates; Lending Offices.

         (a)     Any Bank may, if it so elects, fulfill its Commitment as to
any Eurodollar Loan by causing a branch, foreign or otherwise, or Affiliate of
such Bank to make such Loan and may transfer and carry such Loan at, to or for
the account of any branch office or Affiliate of such Bank;





                                       32
<PAGE>   38
provided that in such event, for the purposes of this Agreement, such Loan
shall be deemed to have been made by such Bank and the obligation of the
Company to repay such Loan shall nevertheless be to such Bank and shall be
deemed to be held by such Bank, to the extent of such Loan, for the account of
such branch or Affiliate.

         (b)     Notwithstanding any provision of this Agreement to the
contrary, each Bank shall be entitled to fund and maintain its funding of all
or any part of its Loans in any manner it sees fit, it being understood,
however, that for the purposes of this Agreement all determinations shall be
made as if such Bank had actually funded and maintained each Eurodollar Loan
during each Interest Period through the purchase of deposits having a maturity
corresponding to such Interest Period and bearing an interest rate equal to the
applicable Eurodollar Rate for such Interest Period.

         2.8.    Several Obligations.  The failure of any Bank to make any Loan
to be made by it on the date specified therefor shall not relieve any other
Bank of its obligation to make its Loan on such date, but neither the Agent nor
any Bank shall be responsible for the failure of any other Bank to make a Loan
to be made by such other Bank.

         2.9.    Notes.  The Loans made by each Bank shall be evidenced by a
single Note of the Company in substantially the form of Exhibit A (each,
together with all renewals, extensions, modifications and replacements thereof
and substitutions therefor, a "Note") payable to the order of such Bank in a
principal amount equal to the Commitment of such Bank as originally in effect
and otherwise duly completed.  Each of the Notes is a refinancing and increase
of Notes under the Existing Credit Facility and shall be entitled to the
benefits of Schedule V to the Existing Credit Facility.  Each Bank is hereby
authorized by the Company to endorse on the schedule (or a continuation
thereof) attached to the Note of such Bank, to the extent applicable, the date,
amount and Type of each Loan made by such Bank to the Company hereunder, and
each Continuation thereof, each Conversion of all or a portion thereof to
another Type, the date and amount of each payment or prepayment of principal
thereof received by such Bank and, in the case of Eurodollar Loans, the length
of each Interest Period; provided that any failure by such Bank to make any
such endorsement shall not affect the obligations of the Company under such
Note or this Agreement in respect of such Loan.

         2.10.   Use of Proceeds.  The proceeds of the Loans shall be used and
the Letters of Credit shall be issued for working capital, for general
corporate purposes of the Company, and for the Acquisition, and may not be
utilized (a) to pay dividends other than usual dividends in the ordinary course
of business or (b) for the buyout or acquisition of any Person unless the board
of directors of such Person has first approved such buyout or acquisition.

         Section 3.       Borrowings and Prepayments.

         3.1.    Borrowings.  The Company shall give the Agent notice of each
borrowing to be made under this Agreement as provided in Section 5.5.  Each
borrowing shall be in an amount of





                                       33
<PAGE>   39
$1,000,000 or any integral multiple thereof.  Not later than 2:00 p.m. on the
date specified for each such borrowing, each Bank shall make available the
amount of the Loan, if any, to be made by it on such date to the Agent, at its
Principal Office, in immediately available funds, for the account of the
Company.  The amounts so received by the Agent shall, subject to the terms and
conditions of this Agreement, be made available to the Company by depositing
the same, in immediately available funds, in an account designated by the
Company and maintained with the Agent at its Principal Office.

         3.2.    Prepayments.

         (a)     Optional Prepayments.  Except as provided in this Section 3.2
or in Section 5 or 6, the Company shall have the right to prepay, on any
Business Day, in whole or in part, without the payment of any penalty or fee,
Loans at any time or from time to time; provided that the Company shall give
the Agent notice of each such prepayment as provided in Section 5.5.
Eurodollar Loans may be prepaid on the last day of an Interest Period
applicable thereto and may not be otherwise prepaid unless prepayment is
accompanied by payment of all compensation required by Section 6.5.

         (b)     Mandatory Prepayments.

                 (1)      Subject to Section 2.4, the Company shall from time
to time on demand by the Agent prepay the Loans or reduce Letter of Credit
Liabilities in such amounts as shall be necessary so that at all times the
aggregate outstanding principal amount of the Loans and Letter of Credit
Liabilities shall not exceed the Available Borrowing Base.  Any such payment
shall be allocated first to Loans, then to Letter of Credit Liabilities and, if
to Letter of Credit Liabilities, first to Reimbursement Obligations and then to
other obligations as the Company may elect.

                 (2)      Concurrently with any Asset Sale of Petroleum
Properties which would cause the aggregate net proceeds of all such Asset Sales
of Petroleum Properties since the effective date of the last calculation of the
Borrowing Base to exceed $20,000,000, the Agent may, and shall at the request
of the Required Banks, redetermine the Available Borrowing Base as of the
effective date of such Asset Sale of Petroleum Properties on the basis of the
information with respect to the remaining Petroleum Properties set forth in the
Most Recent Engineering Report (and, if current, the most recent Company
Report) and the Most Recent Other Liabilities Report.  If a Borrowing Base
Deficiency shall exist as a result of any such redetermination, the Company
shall prepay on the date of such Asset Sale of Petroleum Properties an amount
equal to the lesser of (x) the net proceeds of all such Asset Sales of
Petroleum Properties not previously prepaid and (y) the amount of the Borrowing
Base Deficiency, for application to the Obligations in the priority set forth
in Section 3.2(b)(1).  Should the payment of the net proceeds of all such Asset
Sales of Petroleum Properties not previously prepaid not eliminate the
Borrowing Base Deficiency, Section 2.4 shall apply with respect to any
remaining Borrowing Base Deficiency, except that the Agent need not send any
notice permitted or required by Section 2.4 and the date of such Asset Sale of
Petroleum Properties shall be the equivalent for purposes of Section 2.4 of the
date of the giving of any such notice.





                                       34
<PAGE>   40
                 (3)      The Company shall maintain records of all Asset Sales
of Petroleum Properties and shall otherwise maintain books and records which
enable it to comply, and to demonstrate to the Agent on request compliance,
with the obligations of the Company in this Section 3.2(b).

         Section 4.       Payments of Principal and Interest.

         4.1.    Repayment of Loans and Reimbursement Obligations.   The
Company will pay to the Agent for the account of each Bank the principal of
each Loan made by such Bank on the Maturity Date and the amount of each
Reimbursement Obligation forthwith upon its incurrence.  The amount of any
Reimbursement Obligation may, if the applicable conditions precedent specified
in Section 7 (other than any Default resulting solely from the nonpayment of
such Reimbursement Obligation) have been satisfied, be paid with the proceeds
of Loans.

         4.2.    Interest.

         (a)     Subject to Sections 12.8 and 4.3(b), the Company will pay to
the Agent for the account of each Bank interest on the unpaid principal amount
of each Loan made by such Bank for the period commencing on the date of such
Loan to but excluding the date such Loan shall be paid in full, at the lesser
of (1) the following rates per annum:

                 (A)      if such Loan is an Alternate Base Rate Loan, the
         Alternate Base Rate; or

                 (B)      if such Loan is a Eurodollar Loan, the applicable
         Eurodollar Rate plus the Applicable Margin for Eurodollar Loans;

or (2) the Highest Lawful Rate.

         4.3.    Selection of Interest Rates.

         (a)     Subject to Section 6 and Section 12.8, the Company shall have
the right, by giving a Rate Designation Notice to the Agent as provided in
Section 5.5, to designate any Loan as a Loan of a particular Type, to convert
(a "Conversion") any Loan (in whole or in part) into a Loan of another Type or
to continue (a "Continuation") any Loan (in whole or in part) as a Loan of the
same Type.  The records of the Agent with respect to interest rate
designations, Interest Periods and the amount of Loans to which they are
applicable shall be binding and conclusive, absent manifest error.  Loans shall
be Alternate Base Rate Loans except where the Company has complied with all
requirements of this Agreement for the designation, Conversion or Continuation
of such Loan as a Eurodollar Loan.  Interest on the amount of each Loan shall
accrue on the amount of that Loan and from the date it is made.  Any such
notice of designation, Conversion or Continuation shall specify the new
Interest Period.  In the event the Company fails to so give such notice prior
to the end of any Interest Period for any Eurodollar Loan, such Loan shall
become an Alternate Base Rate Loan on





                                       35
<PAGE>   41
the last day of such Interest Period.  No more than 10 Eurodollar Interest
Periods shall be in effect at any time.  Except as otherwise provided in this
Agreement, each such designation, Conversion or Continuation shall apply to all
Notes ratably in accordance with their respective principal balances.  If any
Bank assigns an interest in its Note when any Eurodollar Loan is outstanding
with respect thereto, the assignee shall have its ratable interest in such
Eurodollar Loan.

         (b)     Notwithstanding the foregoing but subject to Section 12.8, the
Company will pay to the Agent for the account of each Bank interest (i) except
as otherwise provided in clause (ii) or clause (iii) of this Section 4.3(b), at
a rate per annum 2% above the otherwise applicable rate on any principal of any
Loan made by such Bank, for the period commencing on the first day on which any
Specified Event of Default exists and continuing through and including the date
no Specified Event of Default exists and is continuing; (ii) at the rate
provided in Section 2.2 for unpaid Letter of Credit Advances, and (iii) at the
Post-Default Rate for any other amount due under the Credit Documents which is
not paid in full when due (whether at stated maturity, by acceleration, or
otherwise) (but, if such amount is interest, only to the extent legally
enforceable).

         (c)     Accrued interest shall be due and payable on the applicable
Interest Payment Dates, except that (1) accrued interest pursuant to Section
4.3(b) shall be due and payable from time to time on demand of the Agent or the
Required Banks (through the Agent), (2) accrued interest on any amount
converted from one Type of Loan to another Type of Loan shall be paid on the
amount so converted at the time of such Conversion, and (3) accrued interest on
any Eurodollar Loan paid or prepaid shall be due at the time of such payment or
prepayment.

         Section 5.       Payments; Pro Rata Treatment; Computations, Etc.

         5.1.    Payments.

         (a)     Except to the extent otherwise provided in this Agreement, all
payments of principal of or interest on the Loans, of Reimbursement Obligations
and of other amounts to be made by the Company under the Credit Documents shall
be made in dollars, in immediately available funds, to the Agent at its
Principal Office (or in the case of a successor Agent, at the principal office
of such successor Agent in the United States), not later than 12:00 noon on the
date on which such payment shall become due, and each such payment made after
such time on such due date shall be deemed to have been made on the next
succeeding Business Day.  The Agent or any Bank for whose account any such
payment is made, may (but shall not be obligated to) debit the amount of any
such payment which is not made by such time to any ordinary deposit account of
the Company with the Agent or such Bank, as the case may be.

         (b)     The Company shall, at the time it makes each payment under
this Agreement or any other Credit Document, specify to the Agent the Loans or
other amounts payable by the Company to which such payment is to be applied
(and in the event that it fails so to specify, such payment shall be applied as
the Agent may designate to the Loans or other amounts then due and payable);





                                       36
<PAGE>   42
provided that if no Loans or other amounts are then due and payable or an Event
of Default or a Borrowing Base Deficiency has occurred and is continuing, the
Agent may apply any payment to the Obligations in such order as it may elect in
its sole discretion, but subject to the other terms and conditions of this
Agreement, including Section 5.2.  Each payment received by the Agent under
this Agreement or any other Credit Document for the account of a Bank shall be
paid promptly to such Bank in immediately available funds for the account of
such Bank's Applicable Lending Office.

         (c)     If the due date of any payment under this Agreement or any
other Credit Document falls on a day which is not a Business Day, the due date
for such payment (except as otherwise provided in the definition of "Interest
Period") shall be extended to the next succeeding Business Day and interest
shall be payable for any principal so extended for the period of such extension
at the rate in effect on such due date.

         5.2.    Pro Rata Treatment.  Except to the extent otherwise provided
herein, (a) each borrowing from the Banks hereunder, each payment of Commitment
Fees and other fees and each termination or reduction of the Aggregate
Commitment under Section 2.3 shall be made pro rata according to the Banks'
respective Commitment Percentages; (b) except as otherwise provided in this
Agreement, each payment by the Company of principal of or interest on Loans of
a particular Type shall be made to the Agent for the account of the Banks pro
rata according to the Banks' respective Commitment Percentages; and (c) the
Banks (other than the Issuer) shall purchase from the Issuer participations in
each Letter of Credit and its related Letter of Credit Liabilities pro rata
according to the Banks' respective Commitment Percentages.

         5.3.    Computations.  Interest based on the Alternate Base Rate (to
the extent determined by reference to the Prime Rate), and fees hereunder, will
be computed on the basis of 365 (or 366) days and actual days elapsed
(including the first day but excluding the last day) occurring in the period
for which payable.  All other interest and fees shall be computed on the basis
of a year of 360 days and actual days elapsed (including the first day but
excluding the last day) occurring in the period for which payable, unless the
effect of so computing shall be to cause the rate of interest to exceed the
Highest Lawful Rate (in which event interest and fees shall be calculated on
the basis of the actual number of days elapsed in a year composed of 365 or 366
days, as the case may be).

         5.4.    Minimum and Maximum Amounts.  Except for prepayments made
pursuant to Section 3.2(b), each borrowing and repayment of principal of Loans,
each optional partial prepayment and each designation, Continuation or
Conversion of Type shall be in an aggregate principal amount equal to
$1,000,000 or an integral multiple thereof (borrowings or prepayments of Loans
of different Types or, in the case of Eurodollar Loans, having different
Interest Periods at the same time hereunder, to be deemed separate borrowings
and prepayments for purposes of the foregoing, one for each Type or Interest
Period), and each termination or reduction of the Aggregate Commitment shall be
in an aggregate principal amount equal to $5,000,000 or an integral multiple
thereof.  Upon any mandatory prepayment that would reduce Eurodollar Loans
having the same Interest Period to less than $1,000,000, such Eurodollar Loans
shall automatically be converted into





                                       37
<PAGE>   43
Alternate Base Rate Loans.  Each issuance of a Letter of Credit shall be in a
face amount of at least $25,000.

         5.5.    Certain Actions, Notices, Etc.  Notices to the Agent of any
termination or reduction of the Aggregate Commitment, of prepayments of Loans
and of the duration of Interest Periods, each Request for Extension of Credit
and each Rate Designation Notice shall be irrevocable and shall be effective
only if received by the Agent not later than 12:00 noon (1:00 p.m. in the case
of a Request for Extension of Credit or Rate Designation Notice related to a
Eurodollar Loan) on the day that is the applicable number of Business Days
prior to the date of the relevant termination, reduction, issuance, borrowing
and/or prepayment specified below:

</TABLE>

Each such notice of reduction shall specify the amount TO which the Aggregate
Commitment is to be reduced.  Each such notice of prepayment or Request for
Extension of Credit shall specify the amount and Type of such Loans to be
borrowed or prepaid (subject to Sections 3.2 and 5.4), the date of borrowing or
prepayment (which shall be a Business Day) and, in the case of Eurodollar
Loans, the duration of the Interest Period therefor (subject to the definition
of "Interest Period").  Each Rate Designation Notice with respect to a
Conversion of a Loan (or portion thereof) shall specify the amount and Type of
the Loan (or portion thereof) being converted, the amount and Type of Loan into
which such Loan is being converted (subject to Section 5.4), the date for
Conversion (which shall be a Business Day) and, unless such Loan is being
converted into an Alternate Base Rate Loan, the duration (subject to the
definition of "Interest Period") of the Interest Period therefor which is





                                       38
<PAGE>   44
to commence as of the last day of the then current Interest Period therefor (or
the date of Conversion, if such Loan is being converted from an Alternate Base
Rate Loan).  Each Rate Designation Notice with respect to a Continuation of a
Loan (or portion thereof) as the same Type of Loan shall specify the amount and
Type of such Loan (or portion thereof) being continued (subject to Section 5.4)
and the duration (subject to the definition of "Interest Period") of the
Interest Period therefor which is to commence as of the last day of the then
current Interest Period therefor.  The Agent shall promptly notify the Banks of
the contents of each such notice, Request for Extension of Credit, or Rate
Designation Notice.  Notice of any prepayment having been given, the principal
amount specified in such notice, together with interest thereon to the date of
prepayment, shall be due and payable on such prepayment date.

         5.6.    Non-Receipt of Funds by the Agent.  Unless the Agent shall
have been notified by a Bank prior to 2 p.m.  on the date on which such Bank is
to make payment to the Agent of the proceeds of a Loan (or the payment of any
amount by such Bank to reimburse the Issuer for a drawing under any Letter of
Credit) to be made by it hereunder or by the Company prior to the date on which
the Company is to make a payment to the Agent for the account of the Agent, the
Issuer or one or more of the Banks, as the case may be (such Bank or the
Company being herein called the "Payor" and such payment being herein called
the "Required Payment"), which notice shall be effective upon receipt, that the
Payor does not intend to make the Required Payment to the Agent, the Agent may
assume that the Required Payment has been made and may, in reliance upon such
assumption (but shall not be required to), make the amount thereof available to
the intended recipient on the date that such Required Payment is to be made.
If the Payor is the Company and the Company has not in fact made the Required
Payment to the Agent on or before such date, the Banks, ratably in proportion
to their respective Commitment Percentages, shall, on demand, repay to the
Agent the amount made available by the Agent, together with interest thereon
from the date such amount was so made available by the Agent until the date the
Agent recovers such amount at a rate per annum equal to the Fed Funds Rate for
the first three days after demand and thereafter at the Fed Funds Rate plus 2%.
(If the Payor is the Company, the provisions of Section 2.2(a) and Section
4.3(b) shall also apply.)  If the Payor is a Bank and such Bank has not in fact
made the Required Payment to the Agent on or before such date, such Bank shall,
on demand, pay to the Agent the amount made available by the Agent on behalf of
such Bank, together with interest thereon from the date such amount was so made
available by the Agent until the date the Agent recovers such amount at a rate
per annum equal to the Fed Funds Rate for each of the first three days after
demand and for each day thereafter at the Fed Funds Rate plus 2%.

         5.7.    Sharing of Payments, Etc.  If a Bank or any participant of a
Bank shall obtain payment of any principal of or interest on any Loan made by
it under this Agreement or of any Reimbursement Obligation or other obligation
to it under this Agreement, through the exercise of any right of set-off,
banker's lien, counterclaim or similar right, or otherwise, such Bank or
participant shall promptly purchase from the other Banks participations in the
Loans made or Reimbursement Obligations or other obligations held by the other
Banks in such amounts, and make such other adjustments from time to time as
shall be equitable to the end that all the Banks and





                                       39
<PAGE>   45
participants shall share the benefit of such payment (net of any expenses which
may be incurred by such Bank or its participant in obtaining or preserving such
benefit) pro rata in accordance with the respective amounts then due to each of
them.  To such end all the Banks and their participants shall make appropriate
adjustments among themselves (by the resale of participations sold or
otherwise) if such payment is rescinded or must otherwise be restored.  The
Company agrees, to the fullest extent it may effectively do so under applicable
law, that any Person so purchasing a participation in the Obligations may
exercise all rights of set-off, bankers' lien, counterclaim or similar rights
with respect to such participation as fully as if such Bank were a direct
holder of Loans, Reimbursement Obligations or other obligations in the amount
of such participation.  Nothing in this Agreement shall require any Bank to
exercise any such right or shall affect the right of any Bank to exercise, and
retain the benefits of exercising, any such right with respect to any other
indebtedness or obligation of the Company.

         Section 6.       Yield Protection and Illegality.

         6.1.    Additional Costs.

         (a)     Subject to Section 12.8, the Company shall pay to the Agent,
on demand, for the account of such Bank, from time to time such amounts as any
Bank may reasonably determine to be necessary to compensate it for any costs
incurred by such Bank which such Bank reasonably determines are attributable to
its making or maintaining any Eurodollar Loan hereunder or its obligation to
make or maintain any such Loan hereunder, or any reduction in any amount
receivable by such Bank hereunder in respect of any of such Loans or such
obligation (such increases in costs and reductions in amounts receivable being
herein called "Additional Costs"), in each case resulting from any Regulatory
Change which:

                 (1)      subjects such Bank (or makes it apparent that such
Bank is subject) to any tax (including any United States interest equalization
tax), levy, impost, duty, charge or fee (collectively, "Taxes"), or any
deduction or withholding for any Taxes on or from the payment due under any
Eurodollar Loan or other amounts due hereunder, other than income and franchise
taxes of the jurisdiction (or any subdivision thereof) in which such Bank has
an office or its Applicable Lending Office; or

                 (2)      changes the basis of taxation of any amounts payable
to such Bank under this Agreement or its Note in respect of any of such Loans,
other than changes which affect taxes measured by or imposed on the overall net
income or franchise taxes of such Bank or of its Applicable Lending Office for
any of such Loans by the jurisdiction (or any subdivision thereof) in which
such Bank has an office or such Applicable Lending Office; or

                 (3)      imposes or modifies or increases or deems applicable
any Statutory Reserves or any other reserve, special deposit or similar
requirement (including any such requirement imposed by the Board) relating to
any extensions of credit or other assets of, or any deposits with or other





                                       40
<PAGE>   46
liabilities of, such Bank or loans made by such Bank, or against any other
funds, obligations or other property owned or held by such Bank; or

                 (4)      imposes any other condition affecting this Agreement
(or any of such extensions of credit or liabilities).

Each Bank will notify the Company through the Agent of any event occurring
after the date of this Agreement which will entitle such Bank to compensation
pursuant to this Section 6.1 as promptly as practicable after it obtains
knowledge thereof and determines to request such compensation, and (if so
requested by the Company through the Agent) will designate a different
available Applicable Lending Office for the Eurodollar Loans of such Bank or
take such other action as the Company may reasonably request if such
designation or action is consistent with the internal policy of such Bank and
legal and regulatory restrictions, can be undertaken at no additional cost,
will avoid the need for, or reduce the amount of, such compensation and will
not, in the sole opinion of such Bank, be disadvantageous to such Bank
(provided that such Bank shall have no obligation so to designate an Applicable
Lending Office located in the United States of America).  Each Bank will
furnish the Company with a statement setting forth the basis and amount of each
request by such Bank for compensation under this Section 6.1, with each such
statement to cover amounts accruing under this Section 6.1 with respect to a
period beginning not earlier than 120 days from the date thereof and using any
reasonable averaging and attribution methods.

         (b)     Without limiting the effect of the foregoing provisions of
this Section 6.1, in the event that, by reason of any Regulatory Change, any
Bank either (1) incurs Additional Costs based on or measured by the excess
above a specified level of the amount of a category of deposits or other
liabilities of such Bank which includes deposits by reference to which the
interest rate on Eurodollar Loans is determined as provided in this Agreement
or a category of extensions of credit or other assets of such Bank which
includes Eurodollar Loans or (2) becomes subject to restrictions on the amount
of such a category of liabilities or assets which it may hold, then, if such
Bank so elects by notice to the Company (with a copy to the Agent), the
obligation of such Bank to make Eurodollar Loans hereunder shall be suspended
until the date such Regulatory Change ceases to be in effect (in which case the
provisions of Section 6.4 shall be applicable).

         (c)     Determinations and allocations by any Bank for purposes of
this Section 6.1 of the effect of any Regulatory Change on its costs of
maintaining its obligations to make Loans or of making or maintaining
Eurodollar Loans or on amounts receivable by it in respect of Eurodollar Loans,
and of the additional amounts required to compensate such Bank in respect of
any Additional Costs, shall be conclusive, absent manifest error, and may be
made using any reasonable averaging and attribution methods.

         (d)     In the event any Bank shall seek compensation pursuant to this
Section 6.1, the Company may give notice to such Bank (with copies to the
Agent) that it wishes to seek one or more Eligible Assignees (which may be one
or more of the Banks) to purchase and assume the





                                       41
<PAGE>   47
Commitment, Loans, Note, Letter of Credit Liabilities and interests in this
Agreement of such Bank.  Each Bank requesting compensation pursuant to this
Section 6.1 agrees to sell its Commitment, Loans, Note, Letter of Credit
Liabilities and interests in this Agreement pursuant to Section 12.6 (without
recourse, representation or warranty except as provided in Section 12.6) to any
such Eligible Assignee for an amount equal to (x) the sum of the outstanding
unpaid principal of and accrued interest on such Loans, Note and Letter of
Credit Advances, plus (y) in the case of the Issuer, Cover for the face amount
of all undrawn Letter of Credit Liabilities plus (z) all other fees and amounts
(including any compensation claimed by such Bank under this Section 6.1) owing
to such Bank under the Credit Documents, calculated, in each case, to the date
on which such Commitment, Loans, Note, Letter of Credit Liabilities and
interests are purchased, whereupon such Bank shall have no further Commitment
or other obligation to the Company under this Agreement or any other Credit
Document in respect of matters arising after the consummation of such purchase,
but shall continue to be entitled to the benefit of, and subject to any
obligations incurred by it under, this Agreement and the other Credit Documents
in respect of matters occurring during the time it was a Bank under this
Agreement.

         6.2.    Limitation on Types of Loans.  Anything in this Agreement to
the contrary notwithstanding, if, with respect to any Eurodollar Loans:

         (a)     the Agent determines (which determination shall be conclusive
absent manifest error) that quotations of interest rates for the relevant
deposits referred to in the definition of "Eurodollar Rate" in Section 1.1 are
not being provided in the relevant amounts or for the relevant maturities for
purposes of determining the rate of interest for such Loans for Interest
Periods therefor as provided in this Agreement; or

         (b)     the Required Banks determine (which determination shall be
conclusive absent manifest error) and notify the Agent that the relevant rates
of interest referred to in the definition of "Eurodollar Rate" in Section 1.1
upon the basis of which the rates of interest for such Loans are to be
determined do not accurately reflect the cost to such Banks of making or
maintaining such Loans for any proposed Interest Periods therefor; or

         (c)     the Agent determines (which determination shall be conclusive
absent manifest error) that by reason of circumstances affecting the Eurodollar
interbank market generally, deposits in dollars in the relevant Eurodollar
interbank market are not being offered for the applicable Interest Period and
in an amount equal to the amount of the Eurodollar Loan requested by the
Company;

the Agent shall promptly notify the Company and each Bank thereof, and, so long
as such condition remains in effect, the Banks shall be under no obligation to
make Eurodollar Loans (but shall maintain until the end of the Interest Period
then in effect the Eurodollar Loans then outstanding).

         6.3.    Illegality.  Notwithstanding any other provision of this
Agreement to the contrary, if by reason of (x) the adoption or effectiveness of
any applicable Legal Requirement, or any change





                                       42
<PAGE>   48
in any applicable Legal Requirement or in the interpretation or administration
thereof by any Governmental Authority, or compliance by any Bank with any
request or directive (whether or not having the force of law) of any central
bank or other Governmental Authority or (y) circumstances affecting the
relevant Eurodollar interbank market or the position of a Bank therein, it
shall at any time be unlawful or impracticable in the sole discretion of a Bank
for such Bank or its Applicable Lending Office to (a) honor its obligation to
permit the establishment of Eurodollar Loans hereunder or (b) maintain
Eurodollar Loans hereunder, then such Bank through the Agent shall promptly
notify the Company thereof, and the obligation of such Bank to establish or
maintain Eurodollar Loans hereunder shall be suspended until such time as such
Bank may again establish and maintain Eurodollar Loans, in which case the
provisions of Section 6.4 shall be applicable.  Before giving such notice
pursuant to this Section 6.3, such Bank will designate a different available
Applicable Lending Office for the Eurodollar Loans of such Bank or take such
other action as the Company may reasonably request if such designation or
action is consistent with the internal policy of such Bank and legal and
regulatory restrictions, can be undertaken at no additional cost, will avoid
the need to suspend such Bank's obligation to make Eurodollar Loans hereunder
and will not, in the sole opinion of such Bank, be disadvantageous to such Bank
(provided that such Bank shall have no obligation so to designate an Applicable
Lending Office located in the United States of America).

         In the event any Bank shall seek to invoke the benefits of this
Section 6.3, the Company may give notice to such Bank (with copies to the
Agent) that it wishes to seek one or more Eligible Assignees (which may be one
or more of the Banks) to purchase and assume the Commitment, Loans, Note,
Letter of Credit Liabilities and interests in this Agreement of such Bank.
Each Bank requesting to invoke the benefits of this Section 6.3 agrees to sell
its Commitment, Loans, Note, Letter of Credit Liabilities and interests in this
Agreement pursuant to Section 12.6 (without recourse, representation or
warranty except as provided in Section 12.6) to any such Eligible Assignee for
an amount equal to (x) the sum of the outstanding unpaid principal of and
accrued interest on such Loans, Note and Letter of Credit Advances, plus (y) in
the case of the Issuer, Cover for the face amount of all undrawn Letter of
Credit Liabilities, plus (z) all other fees and amounts owing to such Bank
under the Credit Documents, calculated, in each case, to the date on which such
Commitment, Loans, Note, Letter of Credit Liabilities and interests are
purchased, whereupon such Bank shall have no further Commitment or other
obligation to the Company hereunder or any other Credit Document in respect of
matters arising after the consummation of the purchase, but shall continue to
be entitled to the benefit of, and subject to any obligation incurred by it
under, this Agreement and the other Credit Documents in respect of matters
occurring during the time it was a Bank under this Agreement.

         6.4.    Substitute Alternate Base Rate Loans.  If the obligation of
any Bank to make or maintain Eurodollar Loans shall be suspended pursuant to
Section 6.1, 6.2 or 6.3, all Loans which would otherwise be made by such Bank
as Eurodollar Loans shall be made instead as Alternate Base Rate Loans (and, if
an event referred to in Section 6.1(b) or 6.3 has occurred and such Bank so
requests by notice to the Company with a copy to the Agent, each Eurodollar
Loan of such Bank then outstanding shall be automatically converted into an
Alternate Base Rate Loan on the date





                                       43
<PAGE>   49
specified by such Bank in such notice which shall be the last day of the
current Interest Period with respect to such Eurodollar Loan or on such earlier
date as required by law) and, to the extent that such Eurodollar Loans are so
made as (or converted into) Alternate Base Rate Loans, all payments of
principal which would otherwise be applied to such Eurodollar Loans shall be
applied instead to such Alternate Base Rate Loans.

         6.5.    Compensation.  Subject to Section 12.8, the Company shall pay
to the Agent for the account of each Bank, within two Business Days after
demand therefor by such Bank through the Agent, such amount or amounts as shall
be sufficient (in the reasonable opinion of such Bank) to compensate it for any
loss, cost or expense incurred by it as a result of:

         (a)     any payment, prepayment or Conversion of a Eurodollar Loan
made by such Bank on a date other than the last day of an Interest Period for
such Loan; or

         (b)     any failure by the Company to borrow a Eurodollar Loan to be
made by such Bank on the date for such borrowing specified in the relevant
notice of borrowing under Section 5.5 or to convert an  Alternate Base Rate
Loan into a Eurodollar Loan on such date after giving notice of such Conversion
or to continue a Eurodollar Loan after giving notice of such Continuation; or

         (c)     any payment, prepayment or Conversion of a Eurodollar Loan
required by any provision of this Agreement or otherwise made or deemed made on
a date other than the last day of an Interest Period for such Eurodollar Loan;
or

         (d)     any cessation of the Eurodollar Rate to apply to any Loan or
any part thereof;

including, in each case, any actual loss or expense sustained or incurred or to
be sustained or incurred in liquidating or employing deposits acquired to
effect or maintain such Eurodollar Loan or any part thereof. Such compensation
shall include an amount equal to the excess, if any, as reasonably determined
by each Bank, of (1) its cost of obtaining the funds for the Loan being paid,
prepaid or converted or not borrowed, converted or continued (assumed to be the
applicable Eurodollar Rate) for the period from the date of such payment,
prepayment or Conversion or failure to borrow, convert or continue to the last
day of the Interest Period for such Loan (or, in the case of a failure to
borrow, convert or continue the Interest Period for such Loan which would have
commenced on the date of such failure to borrow, convert or continue) over (2)
the amount of interest (as reasonably determined by such Bank) that would be
realized by such Bank in reemploying the funds so paid, prepaid or converted or
not borrowed, converted or continued for such period or Interest Period, as the
case may be.  Each determination of the amount of such compensation by a Bank
shall be conclusive and binding, absent manifest error, and may be computed
using any reasonable averaging and attribution method.

         6.6.    Additional Costs in Respect of Letters of Credit.  If as a
result of any Regulatory Change there shall be imposed, modified or deemed
applicable any tax, reserve, special deposit or





                                       44
<PAGE>   50
similar requirement against or with respect to or measured by reference to
Letters of Credit issued or to be issued under this Agreement or participations
in such Letters of Credit, and the result shall be to increase the cost to the
Issuer or any Bank of issuing or maintaining any Letter of Credit or any
participation therein, or reduce any amount receivable by the Issuer or any
Bank in respect of any Letter of Credit or any participation therein (which
increase in cost, or reduction in amount receivable, shall be the result of
such Issuer's or such Bank's reasonable allocation of the aggregate of such
increases or reductions resulting from such event), such Issuer or such Bank
shall notify the Company through the Agent, and upon demand therefor by such
Issuer or such Bank through the Agent, the Company (subject to Section 12.8)
shall pay to the Issuer or such Bank, from time to time as specified by the
Issuer or such Bank, such additional amounts as shall be sufficient to
compensate the Issuer or such Bank for such increased costs or reductions in
amount.  Before making such demand pursuant to this Section 6.6, the Issuer or
such Bank will designate a different available Applicable Lending Office for
the Letter of Credit or participation or take such other action as the Company
may request, if such designation or action will avoid the need for, or reduce
the amount of, such compensation and will not, in the sole opinion of the
Issuer or such Bank, be disadvantageous to the Issuer or such Bank.  A
statement as to such increased costs or reductions in amount incurred by the
Issuer or such Bank, submitted by the Issuer or such Bank to the Company, shall
cover amounts accruing under this Section 6.6 with respect to a period
beginning not earlier than 120 days from the date thereof, shall be conclusive
as to the amount thereof, absent manifest error, and may be prepared using any
reasonable averaging and attribution method.

         In the event any Bank shall seek compensation pursuant to this Section
6.6, the Company may give notice to such Bank (with copies to the Agent) that
it wishes to seek one or more Eligible Assignees (which may be one or more of
the Banks) to purchase and assume the Commitment, Loans, Note, Letter of Credit
Liabilities and interests in this Agreement of such Bank.  Each Bank requesting
compensation pursuant to this Section 6.6 each agrees to sell its Commitment,
Loans, Note, Letter of Credit Liabilities and interests in this Agreement
pursuant to Section 12.6 (without recourse, representation or warranty except
as provided in Section 12.6) to any such Eligible Assignee for an amount equal
to (x) the sum of the outstanding unpaid principal of and accrued interest on
such Loans, Note and Letter of Credit Advances, plus (y) all other fees and
amounts (including any compensation claimed by such Bank under this Section
6.6) owing to such Bank under the Credit Documents, calculated, in each case,
to the date such Commitment, Loans, Note, Letter of Credit Liabilities and
interests in this Agreement are purchased, whereupon such Bank shall have no
further Commitment or other obligation to the Company under this Agreement or
any other Credit Document in respect of matters arising after the consummation
of such purchase, but shall continue to be entitled to the benefit of, and
subject to any obligation incurred by it under, this Agreement and the other
Credit Documents in respect of matters occurring during the time it was a Bank
under this Agreement.

         In the event any Issuer shall seek compensation pursuant to this
Section 6.6, the Company may give notice to such Issuer (with copies to the
Agent) that it wishes another of the Banks to become the Issuer for future
Letters of Credit (including any Letters of Credit which the Company





                                       45
<PAGE>   51
may arrange to substitute for any Letter of Credit issued by the retiring
Issuer), whereupon such retiring Issuer shall have no further obligation to
issue Letters of Credit, but shall continue to be entitled to the benefit of,
and subject to any obligation incurred by it under, this Agreement and the
other Credit Documents in respect of matters occurring and Letters of Credit
issued during the time it was the Issuer under this Agreement.  Notwithstanding
its retirement, the retiring Issuer shall continue to be entitled to
reimbursement of any and all Letter of Credit Advances made by it under each
Letter of Credit issued by it.  All fees and other amounts (including any
compensation claimed by the retiring Issuer under this Section 6.6) owing to
the retiring Issuer under the Credit Documents shall be paid to the retiring
Issuer at the time of its retirement as Issuer, and the retiring Issuer shall
continue to be the Issuer for all purposes of this Agreement with respect to
any outstanding Letters of Credit theretofore issued by it.

         6.7.    Capital Adequacy.  If any Bank shall have determined that

         (a)     the adoption after the date of this Agreement or the
effectiveness after the date of this Agreement (regardless of whether
previously announced) of any applicable Legal Requirement or treaty regarding
capital adequacy, or

         (b)     any change after the date of this Agreement in any existing or
future Legal Requirement or treaty regarding capital adequacy, or

         (c)     any change after the date of this Agreement in the
interpretation or administration of any existing or future Legal Requirement or
treaty regarding capital adequacy by any Governmental Authority or comparable
agency charged with the interpretation or administration thereof, or

         (d)     compliance by any Bank (or its Applicable Lending Office) with
any request or directive after the date of this Agreement regarding capital
adequacy (whether or not having the force of law) of any such Governmental
Authority or comparable agency has or would have the effect of reducing the
rate of return on the capital of such Bank (or any holding company of which
such Bank is a part) as a consequence of its obligations under this Agreement
and the other Credit Documents to a level below that which such Bank or holding
company could have achieved but for such adoption, change or compliance  by an
amount deemed by such Bank or holding company to be material, then, from time
to time, on demand by such Bank (with a copy to the Agent), the Company
(subject to Section 12.8) shall pay to such Bank such additional amount or
amounts as will compensate such Bank or holding company for such reduction.
The certificate of any Bank setting forth such amount or amounts as shall be
necessary to compensate it and the basis therefor shall cover amounts accruing
under this Section 6.7 with respect to a period beginning not earlier than 120
days from the date thereof and shall be conclusive and binding, absent manifest
error.  The Company shall pay the amount shown as due on any such certificate
upon delivery of such certificate.  In preparing such certificate, a Bank may
take into consideration such Bank's and such holding company's policies with
respect to capital adequacy, employ such assumptions and allocations of





                                       46
<PAGE>   52
costs and expenses as it shall in good faith deem reasonable, and use any
reasonable averaging and attribution method.

         In the event any Bank shall seek compensation pursuant to this Section
6.7, the Company may give notice to such Bank (with copies to the Agent) that
it wishes to seek one or more Eligible Assignees (which may be one or more of
the Banks) to purchase and assume the Commitment, Loans, Note, Letter of Credit
Liabilities and interests in this Agreement of such Bank.  Each Bank requesting
compensation pursuant to this Section 6.7 agrees to sell its Commitment, Loans,
Note, Letter of Credit Liabilities and interests in this Agreement pursuant to
Section 12.6 (without recourse, representation or warranty except as provided
in Section 12.6) to any such Eligible Assignee for an amount equal to (x) the
sum of the outstanding unpaid principal of and accrued interest on such Loans,
Note and Letter of Credit Advances, plus (y) in the case of the Issuer, Cover
for the face amount of all undrawn Letter of Credit Liabilities, plus (z) all
other fees and amounts (including any compensation claimed by such Bank under
this Section 6.7) owing to such Bank under the Credit Documents, calculated, in
each case, to the date on which such Commitment, Loans, Note, Letter of Credit
Liabilities and interests are purchased, whereupon such Bank shall have no
further Commitment or other obligation to the Company under this Agreement or
any other Credit Document in respect of matters arising after the consummation
of such purchase, but shall continue to be entitled to the benefit of, and
subject to any obligation incurred by it under, this Agreement and the other
Credit Documents in respect of matters occurring during the time it was a Bank
under this Agreement.

         Section 7.       Conditions Precedent.

satisfactory to it of the execution and delivery by such Bank of a counterpart
hereof).

         (h)     Consents.  The Agent shall have received evidence satisfactory

<PAGE>   54
         (j)     Other Documents.  The Agent shall have received such other

         (k)     Termination of Existing Credit Facility.  The Agent shall have

         All provisions and payments required by this Section 7.1 are subject
to the provisions of Section 12.8.

         7.2.    All Loans and Letters of Credit.  The obligation of each Bank
to make any Loan (including its initial Loan) to be made by it hereunder and
the obligation of the Issuer to issue any Letter of Credit (including the first
Letter of Credit) are each subject to the additional conditions precedent that,
as of the date of such Loan or such issuance, and after giving effect thereto:

         (a)     no Default shall have occurred and be continuing and no
Borrowing Base Deficiency shall exist;

         (b)     there shall have been no Material Adverse Change since
December 31, 1996; provided, however, that at all times when the Company's
unsecured and unenhanced senior long-term debt is rated at least BBB- (or its
equivalent) by S&P or at least Baa3 (or its equivalent) by Moody's, the date
"December 31, 1996" in the previous clause shall instead be "the effective date
of the Company's most recent audited financial statements delivered to the
Agent";

         (c)     all representations and warranties made in each Credit
Document (other than in Section 8.2(b) of this Agreement) shall be true and
correct in all material respects on and as of the date of the making of such
Loan or the issuance of such Letter of Credit, with the same force and effect
as if made on and as of such date (except as the same are expressly stated in
the Credit Documents to be made only as of a specific earlier date, in which
case the same shall have been true and correct in all material respects as of
such earlier date, and except that insofar and insofar only as they apply to or
involve McFarland, the representations and warranties in Sections 8.1, 8.3,
8.4, 8.5, 8.8, 8.9, 8.13 and 8.14 shall be made only in connection with Loans
and Letters of Credit, in each case requested on or after December 31, 1997);

         (d)     except for Loans and Letters of Credit made or issued on the
date of this Agreement, and except for Existing Letters of Credit, the Company
shall have delivered to the Agent a Request for Extension of Credit (and, in
the case of a Letter of Credit, a completed Application) within the time
specified in Section 5.5; and





                                       49
<PAGE>   55
         (e)     the making of such Loan or the issuance of such Letter of
Credit shall not be prohibited by, or subject the Agent or such Bank to any
penalty under, any Legal Requirement applicable to the Agent or such Bank.

         The borrowing of the initial Loans and the issuance of the initial
Letter of Credit under this Agreement and each Request for Extension of Credit
in respect of each Loan and each Letter of Credit by the Company hereunder
shall constitute and include a representation and warranty by the Company to
the effect set forth in subsections (a) through (c) (if applicable) of this
Section 7.2 (both as of the date of such notice and, unless the Company
otherwise notifies the Agent prior to the date of such borrowing or issuance,
as of the date of such borrowing or issuance).  Except in the case of Loans and
Letters of Credit made or issued on the date hereof, such representation and
warranty shall be accompanied by a certificate of the Chief Executive Officer,
President, Chief Financial Officer or Treasurer of the Company setting forth in
reasonable detail the calculations of the Company in making such representation
and warranty.

         7.3.    Conversions into and Continuations of Eurodollar Loans.  The
obligation of each of the Banks to convert any Alternate Base Rate Loan into a
Eurodollar Loan or to continue any Eurodollar Loan for a new Interest Period is
subject to the conditions precedent that on the date of such Conversion or
Continuation and after giving effect thereto (a) no Default shall have occurred
and be continuing, (b) the Company shall have delivered to the Agent a Rate
Designation Notice within the time specified in Section 5.5, and (c) such
Conversion or Continuation shall not be prohibited by, or subject such Bank to
any penalty under, any Legal Requirement applicable to such Bank.  The
acceptance of the benefits of such Conversion or Continuation shall constitute
a representation and warranty by the Company to each of the Banks to the effect
set forth in clause (a) Eurodollar Loans may be converted into Alternate Base
Rate Loans at any time provided that (a) the Company shall have delivered to
the Agent a Rate Designation Notice within the time specified in Section 5.5,
and (b) such Conversion or Continuation shall not be prohibited by, or subject
such Bank to any penalty under, any Legal Requirement applicable to such Bank.

         Section 8.       Representations and Warranties.  To induce the Agent
and the Banks to enter into this Agreement and to extend credit under it, the
Company represents and warrants (such representations and warranties to survive
any investigation, the making of the Loans and the issuance of the Letters of
Credit) to the Banks and the Agent as follows:

         8.1.    Corporate Existence.  Each member of the Combined Group (a) is
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization; (b) has all requisite power and authority,
and has all licenses, permits, authorizations, consents and approvals
necessary, to own its property and carry on its business as now being
conducted, and (c) is qualified to do business, and is in good standing, in all
jurisdictions in which any of the Petroleum Properties which it owns are
located or the nature of the business conducted by it makes such qualification
necessary or advisable, unless the failure to be so qualified or in good
standing would not individually or in the aggregate have a material adverse
effect on the business, financial





                                       50
<PAGE>   56
condition or results of operations of the Combined Group taken as a whole.  The
Company is qualified to do business and is in good standing in the State of
California.

         8.2.    Information.

         (a)     The most recent consolidated balance sheet of the Company and
its Subsidiaries and the related consolidated statements of operations, changes
in financial position and cash flows for the period then ended, together with
the respective notes thereto, delivered to each of the Banks in accordance with
the provisions of Section 9.1(a) or (b), as the case may be (the latest of such
financial statements and the notes thereto being referred to herein as the
"Most Recent Financial Statements"), fairly present in all material respects
the consolidated financial position of the Company and its Subsidiaries as of
such date and their consolidated results of operations for the period then
ended in conformity with GAAP.

         (b)     Since the date of this Agreement, there has been no Material
Adverse Change.

         8.3.    Litigation; Compliance.  Except as disclosed in writing to the
Banks prior to the date hereof, there are no legal or arbitral proceedings or
any proceedings by or before any Governmental Authority now pending, or, to the
knowledge of the Company, threatened, against or affecting the Company or any
of its Subsidiaries which, if adversely determined, would cause a Material
Adverse Change.  The Company and its Subsidiaries comply in all material
respects with all applicable material (based on the Company and its
Subsidiaries taken as a whole) Legal Requirements (other than the Applicable
Environmental Laws, representations and warranties regarding which are found in
Section 8.13).  Neither the Company nor any of its Subsidiaries is in default
in any material respect under, or in violation of, any material (based on the
Company and its Subsidiaries taken as a whole) judgment, order or decree of any
Governmental Authority.

         8.4.    No Breach.  None of the execution and delivery of the Credit
Documents, the consummation of the transactions therein contemplated or
compliance with the terms and provisions thereof will conflict with or result
in a breach of, or require any consent that has not been obtained under, the
Organizational Documents of the Company or any of its Subsidiaries or any
material Legal Requirement (including any securities law, rule or regulation)
applicable to the Company or any of its Subsidiaries or (except for the Liens
permitted by this Agreement) result in the creation or imposition of any Lien
upon any of the revenues or property of the Company or any of its Subsidiaries.
Such execution, delivery, consummation and compliance do not and will not
conflict with or result in a breach of any material agreement or instrument to
which the Company or any of its Subsidiaries is a party or by which the Company
or any of its Subsidiaries is bound or to which any of them is subject, or
constitute a default under any such agreement or instrument.

         8.5.    Necessary Action.  The Company has all necessary power and
authority to execute, deliver and perform its obligations under the Credit
Documents and the documentation necessary to consummate the transactions
contemplated therein and the Acquisition.  The execution, delivery





                                       51
<PAGE>   57
and performance of the Credit Documents by the Company and the consummation by
the Company of the transactions contemplated therein have been duly authorized
by all necessary action on the part of the Company.  The Credit Documents have
been duly and validly executed and delivered by the Company and constitute the
legal, valid and binding obligations of the Company, enforceable in accordance
with their respective terms, except as the enforceability thereof may be
limited by bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium or other similar laws relating to the enforcement of creditors'
rights generally and by general equitable principles.

         8.6.    Approvals.  All authorizations, approvals and consents of, and
all filings and registrations with, all Governmental Authorities, the holders
of the Senior Notes and each other Person necessary for the execution, delivery
or performance of any Credit Document, the consummation by the Company of the
transactions contemplated therein, or the Acquisition, or for the validity or
enforceability of the Credit Documents have been obtained and are in full force
and effect.

         8.7.    Regulations G, T, U and X.  Neither the Company nor any agent
acting on its behalf has taken or will take any action which might cause this
Agreement, the Loans or the Notes to violate Regulation G, T, U or X or any
other regulation of the Board or to violate the Securities Exchange Act of
1934, as amended, in each case as in effect now or as the same may hereafter be
in effect.  "Margin stock" (as defined in Regulations G, T, and U) does not,
and giving effect to the acquisition of all of the stock of McFarland will not,
constitute 25% or more of the assets of the Company and its Subsidiaries, and
the Company does not intend or foresee that such margin stock will constitute
25% or more of such assets at any time during the term of this Agreement.  The
parties acknowledge that neither the Agent nor any Bank is relying upon as
collateral any margin stock, whether issued by the Company, currently owned by
the Company or any Restricted Subsidiary or intended to be acquired by the
Company or any Restricted Subsidiary.  The Company warrants and covenants that
it shall not take any action that would result, in the absence of the
application of the following sentence, in any credit that may be (or that may
have been) advanced under this Agreement being classified as purpose credit
directly or indirectly secured by margin stock within the meaning of Regulation
U.  Notwithstanding any term contained in this Agreement to the contrary, if
any purpose credit extended or deemed to be extended under this Agreement
should nevertheless ever be deemed to be indirectly secured by margin stock,
then, during such time that such condition exists:  (i) the Company (without
regard to any restriction contained in the Credit Documents) may sell, pledge
or otherwise dispose of the Excess Portion of margin stock (and the exercise of
such right shall not constitute cause for accelerating the maturity of the
Obligations); and (ii) the Company shall not utilize any of its assets that are
not margin stock to acquire any margin stock directly or indirectly.  As used
in this Section 8.7:  (A) "Regulation U" means those regulations concerning
credit provided by banks for the purpose of purchasing or carrying margin stock
set forth at Part 211 of Volume 12 of the Code of Federal Regulations, as the
same may be amended from time to time; (B) "indirectly secured" and "purpose
credit" shall have the meanings ascribed to those phrases in Section 221.2 of
Regulation U; (iii) "Excess Portion of margin stock" means that portion of the
margin stock directly or indirectly owned by the Company (and, where the value
of all margin





                                       52
<PAGE>   58
stock so owned by the Company exceeds the Regulation U Limit, the Company shall
promptly identify to the Agent the particular shares from among them which
shall be included in such portion exceeding the Regulation U Limit) that has a
value, when added to the value of all other margin stock indirectly securing
the credit extended under this Agreement, that would cause the total value of
the margin stock indirectly securing the credit to exceed the Regulation U
Limit; and (iv) "Regulation U Limit" means that amount equal to twenty-five
(25%) of the value of the Company's properties or assets that are then subject
to any restriction in this Agreement on the disposition thereof or the creation
of Liens thereon.

         8.8.    ERISA.  The Company and each ERISA Affiliate have fulfilled
their contribution obligations under each Plan subject to Title IV of ERISA and
have fulfilled their obligations under the minimum funding standards of ERISA
and the Code with respect to each Plan subject to Title IV of ERISA, and in all
other regards with respect to each Plan are in material compliance with the
applicable provisions of ERISA, the Code, and all other applicable laws,
regulations and rules, to the extent that noncompliance with such provisions
would result in a Material Adverse Change.  The Company has no knowledge of any
event with respect to each Plan which could result in a Material Adverse
Change.

         8.9.    Taxes.  Each of the Company and its Subsidiaries has filed all
United States federal income tax returns and all other material tax returns
which are required to be filed by it and has paid all taxes due pursuant to
such returns or pursuant to any assessment received by it, except to the extent
the same may be contested in good faith by appropriate proceedings diligently
conducted for which adequate reserves have been established in accordance with
GAAP.  The charges, accruals and reserves on the books of the Company and its
Subsidiaries in respect of taxes and other governmental charges, as made on a
periodic basis, are adequate.

         8.10.   Subsidiaries.  Schedule I as supplemented from time to time by
notice from the Company to the Agent is a complete and correct list of all
Subsidiaries of the Company.  All shares or other indicia of equity interest of
the Restricted Subsidiaries directly or indirectly owned by the Company are
free and clear of Liens (except Permitted Encumbrances and Liens permitted by
Section 9.7(a)(7)), and all such shares are validly issued, fully paid and
non-assessable.

         8.11.   Investment Company Act.  No member of the Combined Group is an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended, or directly or indirectly controlled by or acting on behalf of any
Person which is an "investment company", within the meaning of said Act.

         8.12.   Public Utility Holding Company Act; Federal Power Act.  No
member of the Combined Group is a "public utility company", or an "affiliate"
or a "subsidiary company" of a "public utility company", or a "holding
company", or an "affiliate" or a "subsidiary company" of a "holding company" or
of a "subsidiary company" of a "holding company," as such terms are defined





                                       53
<PAGE>   59
in the Public Utility Holding Company Act of 1935, as amended, or a "public
utility" as such term is defined in the Federal Power Act, as amended.

         8.13.   Environmental Matters.  Except as disclosed in writing to the
Agent prior to the date hereof, the Company and its Subsidiaries, and the
plants and sites of each, have complied with all Applicable Environmental Laws,
except, in any such case, where such failure to so comply would not result in a
Material Adverse Change.  Without limiting the generality of the preceding
sentence, neither the Company nor any of its Subsidiaries has received notice
of or has actual knowledge of any actual or claimed or asserted failure so to
comply with Applicable Environmental Laws or of any other Environmental Claim
which alone or together with all other such failures or Environmental Claims is
material and would result in a Material Adverse Change.  Except as disclosed in
writing to the Agent prior to the date hereof, neither the Company nor any of
its Subsidiaries nor their plants or other sites manage, generate or dispose
of, or during their respective period of use, ownership, occupancy or operation
by the Company or its Subsidiaries have managed, generated, released or
disposed of, any hazardous wastes, solid wastes, petroleum substances,
hazardous substances, hazardous materials, toxic substances or toxic
pollutants, as those terms are used or defined in the Applicable Environmental
Laws, in material violation of or in a manner which would result in liability
under the Applicable Environmental Laws or any other applicable Legal
Requirement, or in a manner which would result in an Environmental Claim except
where such noncompliance or liability or Environmental Claim would not result
in a Material Adverse Change.  The representation and warranty contained in
this Section 8.13 is based in its entirety upon (a) current interpretations and
enforcement policies that have been publicly disseminated and are used by
Governmental Authorities charged with the enforcement of the Applicable
Environmental Laws or which apply to the Company or any of its Subsidiaries
with respect to any property or sites in a particular jurisdiction and (b)
current levels of publicly disseminated scientific knowledge concerning the
detection of, and the health and environmental risks associated with the
discharge of, substances and pollutants regulated pursuant to the Applicable
Environmental Laws.

         8.14.   Title.

         (a)     Each member of the Combined Group has good and defensible
title to the oil, gas and mineral properties shown as owned by it and included
in the Most Recent Engineering Report furnished to the Banks.

         (b)     Such properties and facilities are free and clear of all
Liens, except Permitted Encumbrances and other Liens permitted hereby.

         (c)     All oil, gas and mineral leases and leasehold estates, gas
purchase and sales contracts and other agreements comprising or relating to any
of such properties are valid and subsisting and in full force and effect,
except for those leases, estates, contracts, easements, rights-of-way and
agreements which are in the aggregate not material to oil, gas and mineral
properties included in the Most Recent Engineering Report furnished to the
Banks, taken as a whole.





                                       54
<PAGE>   60
         (d)     All rights, permits, easements, servitudes and rights-of-way,
failure to have or maintain which would materially interfere with the
development, maintenance and operation of such properties so as to cause a
Material Adverse Change, have been obtained and are in full force and effect.

         8.15.   Restricted Investments.  On the date of this Agreement, the
Company and its Subsidiaries own no Restricted Investments.

         Section 9.       Covenants.  The Company covenants to and agrees with
the Banks and the Agent that until the termination of this Agreement pursuant
to Section 12.7:

         9.1.    Financial Statements and Certificates.  The Company will
deliver in duplicate:

         (a)     to each Bank, (A) as soon as practicable and in any event
within 60 days after the end of each quarterly period (other than the last
quarterly period) in each fiscal year, commencing with the quarterly period
ending September 30, 1997, consolidated and consolidating statements of
operations, stockholders' equity and cash flows of the Company and its
Subsidiaries for the period from the beginning of the then-current fiscal year
to the end of such quarterly period, and a consolidated and consolidating
balance sheet of the Company and its Subsidiaries as of the end of such
quarterly period, setting forth (1) as to each account affected thereby, all
eliminating entries for the Unrestricted Subsidiaries as a group and (2) the
resulting consolidated and consolidating figures for the Company and the
Restricted Subsidiaries, and on and after December 31, 1997, setting forth in
each case in comparative form figures as of the end of and for the
corresponding period in the preceding fiscal year, all in reasonable detail and
unaudited but certified by an authorized financial officer of the Company as
fairly presenting the financial position and results of operations of the
Company and its Subsidiaries as of the date thereof and the period then ended,
subject to changes resulting from year-end adjustments; provided, however, that
delivery of copies of the Quarterly Report on Form 10-Q of the Company for such
quarterly period filed with the Securities and Exchange Commission shall be
deemed to satisfy the requirements of this clause (A) with respect to
consolidated financial statements if such financial statements are included in
such report; and (B) prior to the consummation of the Spin-Off, as soon as
practicable and in any event within 60 days after the end of each quarterly
period (other than the last quarterly period) in each fiscal year, consolidated

December 31, 1997, setting forth in each case in comparative form figures for
the corresponding period in the preceding fiscal year, all in reasonable detail
and unaudited but certified by an authorized financial officer of SFER, subject
to changes resulting from year- end adjustments; provided, however, that
delivery of copies of the Quarterly Report on Form 10-Q of SFER for such
quarterly period filed with the Securities and Exchange Commission shall be
deemed to satisfy the requirements of this clause (B) with respect to
consolidated financial statements if such financial statements are included in
such report;

<PAGE>   61
         (b)     to each Bank, (A) as soon as practicable and in any event
within 120 days after the end of each fiscal year, commencing with the year
ending December 31, 1997, consolidated and consolidating statements of
operations, stockholders' equity and cash flows of the Company and its
Subsidiaries for such year, and a consolidated and consolidating balance sheet
of the Company and its Subsidiaries as of the end of such fiscal year, setting

Unrestricted Subsidiaries as a group and (2) the resulting consolidated and
consolidating figures for the Company and the Restricted Subsidiaries, and on

unqualified as to the scope or limitations imposed by the Company and shall not
be subject to any other material qualification and (B) state that such
financial statements present fairly, in all material respects, the financial
position of the Company and its Subsidiaries at the dates indicated and their
cash flows and the results of their operations and the changes in their
financial position for the periods indicated in conformity with GAAP, and shall
be accompanied by a report of such independent public accountants stating that
(W) such audit was made for the purpose of forming an opinion on the
consolidated financial statements taken as a whole; (X) the consolidating
information set forth therein is presented for purposes of additional analysis
rather than to present the financial position, results of operations and cash
flows of the individual companies; (Y) such consolidating information has been
subjected to the auditing procedures applied in the audit of the basic
financial statements, and (Z) in such independent public accountants' opinion,
such consolidating information is fairly stated in all material respects in
relation to the consolidated financial statements taken as a whole, with such
changes thereto as such accountants reasonably determine to be appropriate
under the circumstances; provided, however, that delivery of copies of the
Annual Report on Form 10-K of the Company for such fiscal year filed with the
Securities and Exchange Commission shall be deemed to satisfy the requirements
of this clause (A) with respect to consolidated financial statements if such
financial statements are included in such report; and (B) prior to the

independent public accountants stating that such audit was made for the purpose
of forming an opinion on the consolidated financial statements taken as a
whole, with such changes thereto as such accountants





                                       56
<PAGE>   62
reasonably determine to be appropriate under the circumstances; provided,
however, that delivery of copies of the Annual Report on Form 10-K of SFER for
such fiscal year filed with the Securities and Exchange Commission shall be
deemed to satisfy the requirements of this clause (B) with respect to
consolidated financial statements if such financial statements are included in
such report;

         (c)     to each Bank, promptly upon transmission thereof, copies of
all financial statements, proxy statements, notices and reports as it shall

Company, would cause a Material Adverse Change (to the extent affecting the
Company and its Subsidiaries in a materially different manner or extent than
the oil and gas industry generally); (2) that any Person has given any notice
to the Company or any of its Subsidiaries or taken any other action with
respect to a claimed default or event or condition of the type referred to in

determination in any court proceeding in any litigation involving a potential
liability to the Company or any of its Subsidiaries equal to or greater than
$7,500,000 with respect to any single cause of action which makes the
likelihood of an adverse determination in such litigation against the Company
or such Subsidiary substantially more probable; (4) of any regulatory
proceeding which, if determined adversely to the Company, would cause a
Material Adverse Change (to the extent affecting the Company and its
Subsidiaries in a materially different manner or extent than the oil and gas

Additionally, the Company will deliver to each Bank:

         (x)     Together with each delivery of financial statements required

9.7(b)(2) and (3), 9.7(c), 9.7(d), 9.7(e), 9.7(f), 9.9, 9.10 and 9.11 as at the

obtained knowledge of any such Default, specifying the nature and period of
existence thereof.  Such accountants, however, shall not be liable to the Agent
or any Bank by reason of their failure to obtain knowledge of any such Default
which would not be disclosed in the course of an audit conducted in accordance
with generally accepted auditing standards.  The Company also covenants that
forthwith upon the Chief Executive Officer, Principal Financial Officer or
principal accounting officer obtaining knowledge of an Event of Default or
Default, it will deliver to each Bank an Officer's Certificate specifying the
nature and period of existence thereof and what action the Company proposes to
take with respect thereto.

each of its Subsidiaries to permit, any Person designated in writing by any
Bank, at such Bank's expense and risk, to visit and inspect any of the
properties of the Company and its Subsidiaries; and also to examine the
corporate books and financial records of the Company and its Subsidiaries and
to make copies thereof or extracts therefrom and to discuss the affairs,
finances and accounts of such Persons with the executive officers of the
Company and its Subsidiaries, the petroleum reserve engineers employed by the
Company and its Subsidiaries and the Company's independent public accountants,
all at such reasonable times, with a representative of the Company present and
as often as such Bank may reasonably request, and will assist such Person or
Persons in all such activities.

         9.3.    Compliance with Environmental Laws.  The Company will, and
will cause each of its Subsidiaries and each of its Affiliates that are
controlled by the Company or its Subsidiaries to, comply in a timely fashion
with, or operate pursuant to valid waivers of the provisions of, all Applicable
Environmental Laws, except where non-compliance would neither (a) result in a
Material Adverse Change nor (b) subject the Agent or any Bank to any liability
for such non-compliance (provided that the Company shall not be in default of
this clause (b) if the Company indemnifies each of the Agent, Banks or any of
them subjected to such liability and provides collateral to secure such
indemnification, all to the extent required by the Person subjected to such
liability in its sole and unfettered discretion).  THE COMPANY AGREES TO
INDEMNIFY AND HOLD THE AGENT AND EACH BANK, AND THEIR RESPECTIVE OFFICERS,

WHICH ANY SUCH PERSON MAY INCUR OR SUFFER AS A RESULT OF A BREACH BY THE
COMPANY OR ITS SUBSIDIARIES OR AFFILIATES, AS THE CASE MAY BE, OF THIS
COVENANT.  The Company shall not be deemed to have breached or violated this
Section 9.3 if the Company or the applicable Subsidiary or Affiliate, as the
case may be, is challenging in good faith by appropriate proceedings diligently
pursued, and subject to the indemnification obligations of this Section 9.3,
the application or enforcement of any such Applicable Environmental Laws for
which adequate reserves have been established in accordance with GAAP.

         9.4.    Payment of Taxes.  The Company will, and will cause each of
its Subsidiaries to, pay, or have paid on its behalf, before the same become
delinquent all taxes, assessments and governmental charges imposed upon it or
upon its property, except to the extent contested in good faith by appropriate
proceedings diligently conducted for which adequate reserves have been
established in accordance with GAAP.

         9.5.    Maintenance of Insurance.  The Company and each of its
Subsidiaries will carry and maintain insurance (subject to self-insurance in
the maximum amount of $10,000,000, customary deductibles and retentions) in at
least such amounts and against such liabilities and hazards and by such methods
as customarily maintained by other companies operating similar businesses and,
together with each delivery of financial statements required by Section 9.1(b)
will deliver to the Agent for each Bank an Officer's Certificate specifying the
details of such insurance in effect.  Upon the request of the Agent or any
Bank, the Company shall promptly deliver to the Agent one or more current
certificates of the insurer or insurers providing the insurance required by
this Section 9.5 to the effect that such insurance may not be canceled, reduced
or affected in any manner without 30 days' prior written notice to the Agent.

         9.6.    Restricted Payments and Restricted Investments.  The Company
will not and will not permit any Restricted Subsidiary to (a) make any
Restricted Investment or (b) pay or declare any dividend on any class of its
stock or make any other distribution on account of any class of its stock, or
redeem, purchase or otherwise acquire, directly or indirectly, any shares of
its stock (all of the foregoing described in subsection (b) above being herein
called "Restricted Payments") (1) except out of Consolidated Net Earnings
Available for Restricted Payments and Restricted Investments; and (2) unless,
after giving effect to any such Restricted Investment or Restricted Payment, as
the case may be, no Default and no Borrowing Base Deficiency shall have
occurred and be continuing.

         Notwithstanding the foregoing, the Company will not, in any event, in
any fiscal year prior to the fiscal year in which the Spin-Off is consummated
and, in the case of the fiscal year in which the Spin-Off is consummated, the
portion of the fiscal year preceding the consummation of the Spin-Off, make
Restricted Payments to or Restricted Investments in SFER or any Ineligible
Subsidiary in excess of $31,000,000 in the aggregate for each such fiscal year
or portion thereof.

         (b)     the sum of all Restricted Investments and all Restricted
Payments made on or after the Commencement Date.

         There shall not be included in Restricted Payments or in any

liabilities, for goods and services in the ordinary course of business and on
terms and conditions which are customary in the oil, gas and mineral

properties to less than (A) the "Net Revenue Interest" set forth in the Most
Recent Engineering Report for those oil and gas properties included in the Most
Recent Engineering Report or (B) the net revenue interest so acquired for those
oil and gas properties acquired after the date of the Most Recent Engineering

commencement of construction, development or improvement thereof, as the case
may be, to secure all or a portion of (or to secure Debt incurred to pay all or
a portion of) the purchase price of such acquisition, or the cost of such
construction, development or improvement, as the case may be; provided that (A)
such property is not and shall not thereby become encumbered in an amount in

corporation) or with any one or more other wholly-owned Restricted
Subsidiaries;

state thereof and having at least 80% of its consolidated assets located in the
United States of America and Canada which expressly assumes in writing the due
and punctual performance of the obligations of the Company under the Credit
Documents, to the same extent as if such successor or transferee corporation
had originally executed the Credit Documents in the place of the Company (it
being agreed that such assumption shall, upon the request of any Bank and at
the expense of such successor or transferee corporation, be evidenced by the
exchange of such Bank's Note for another Note executed by such successor or
transferee corporation, with such changes in phraseology and form as may be
appropriate but in substance of like terms as the Note surrendered for such
exchange and of like unpaid principal amount, and that each Note executed
pursuant to this Agreement after such assumption shall be executed by and in
the name of such successor or transferee corporation);

provided that for purposes of Sections 9.7(d)(6) and (7) immediately after such

sale or other disposition described in Section 9.7(d)(7), the Company shall
give written notice thereof to each Bank describing in reasonable detail the
proposed transaction, the date on which it is proposed to be consummated and
the identity, jurisdiction of organization, and geographic composition of
assets of the proposed successor or transferee corporation.  No disposition by
the Company of its assets as an entirety or substantially as an entirety under
Section 9.7(d)(7) shall release the Company as the maker of the Notes from its
liability as obligor thereon.

Transaction unless:

                 (1)      the net sales proceeds received by the Company or a
Restricted Subsidiary in respect of the assets sold pursuant to such Sale and
Leaseback Transaction are greater than or equal to the fair market value of the

cost of which shall be borne exclusively by the Company) as to valuation from
an independent valuation expert selected by the Company) and such proceeds are
concurrently applied to (A) the purchase, acquisition, development or
construction of assets having a value at least equal to such net proceeds, and
to be used in the Company's or such Restricted Subsidiary's business; provided
that no Liens shall at any time exist on such assets which secure any Debt
except as permitted by Section 9.7(a)(1), (2), (3) or (11); (B) the prepayment
in accordance with this Agreement of any aggregate principal amount of all the
Obligations (plus accrued interest and premium, if any) at least equal to the

proceeds; or

                 (2)      the Sale and Leaseback Transaction involves the sale
of assets by the Company to a wholly-owned Restricted Subsidiary or by a
Restricted Subsidiary to the Company or to another wholly-owned Restricted
Subsidiary; provided that if the Company is the seller under any such Sale and
Leaseback Transaction, its lease obligations thereunder shall be subordinated
to the Funded Debt represented by the Notes upon terms set forth on Schedule V.

         (f)     Transactions with Affiliates.  Except for the Other
Transactions, or as provided in the second paragraph of Section 9.6, directly
or indirectly purchase, acquire or lease any property from, or sell, transfer
or lease any property to, or otherwise deal with, in the ordinary course of
business or otherwise, (1) any Affiliate (except any employee compensation
benefit plan or any Restricted Subsidiary) or (2) any Person (other than a
Restricted Subsidiary) in which an Affiliate or the Company (directly or
indirectly) owns, beneficially or of record, 5% or more of the outstanding
voting stock or similar equity interest, except that (A) any Affiliate may be a
director, officer or employee of the Company or any Restricted Subsidiary and
may be paid reasonable compensation in connection therewith and (B) acts and
transactions that would otherwise be prohibited by this subsection may be
performed or engaged in if upon terms not less favorable to the Company or any
Restricted Subsidiary than if no relationship described in clauses (1) and (2)
above existed.

         (g)     Tax Consolidation.  Except as provided for in the Tax
Allocation Agreement or the Spin-Off Tax Indemnification Agreement, the Company
will not, and will not permit any of its Subsidiaries to, file or consent to
the filing of any consolidated income tax return with any Person





                                       68
<PAGE>   74
unless such other Person shall have agreed in writing with the Company that the
Company's or such Subsidiary's liability with respect to taxes as a result of
the filing of any such consolidated income tax return with such Person shall
not be materially greater, nor the receipt of any tax benefits materially less,
than they would have been had the Company and its Subsidiaries continued to
file a consolidated income tax return with the Company as the parent
corporation.

         9.8.    Issuance of Stock by Restricted Subsidiaries.  The Company
will not permit any Restricted Subsidiary (either directly or indirectly, by
the issuance of rights or options for, or securities convertible into, such
shares) to issue, sell or otherwise dispose of any shares of any authorized but
unissued or treasury class of such Restricted Subsidiary's stock (other than
directors' qualifying shares) except to the Company or another Restricted
Subsidiary.

         9.9.    Consolidated Net Worth.  The Company will not permit
Consolidated Net Worth (a) on any date before January 1, 2000, to be less than
$115,000,000 and (b) on January 1, 2000 or on any date thereafter to be less
than the sum of (i) $115,000,000 plus (ii) to the extent positive, 20% of
Consolidated Net Earnings for each fiscal year beginning with the fiscal year
beginning January 1, 1999 and ending on the last day of the fiscal year most
recently ended; provided, that the covenant contained in this Section 9.9 may
be modified from time to time as the corresponding covenant in the Note
Agreement is modified (such modification to occur, if at all, on or before 30
days after modification of the corresponding covenant in the Note Agreement)
and will cease to apply when that corresponding covenant ceases to apply.

         9.10.   Interest Coverage.  The Company will not permit the ratio of
(a) EBITDA for the four fiscal quarters then most recently ended to (b) Fixed
Charges on Total Debt of the Combined Group for that period to be less than
3.00 to 1.00.

         9.11.   Total Debt and Special Debt.  The Company will not at any time
create, incur, assume or suffer to exist any Total Debt of the Combined Group
other than Total Debt of the Combined Group which does not at any time exceed
the product of (a) 3.00 times (b) Adjusted EBITDA for the four consecutive
fiscal quarters then most recently ended; provided, that the covenant contained
in this sentence may be modified from time to time as the corresponding
covenant in the Note Agreement is modified (such modification to occur, if at
all, on or before 30 days after modification of the corresponding covenant in
the Note Agreement) and "3.00" shall be changed to be "3.50" when that
corresponding covenant ceases to apply.  The aggregate principal amount of
Special Debt shall not exceed 15% of Consolidated Net Worth.

         9.12.   Covenants in Other Agreements.  The Company shall not, and
shall not permit any of its Subsidiaries to, become a party to or agree that it
or any of its property is bound by any indenture, mortgage, deed of trust or
any other agreement or instrument directly or indirectly:





                                       69
<PAGE>   75
         (a)     restricting any loans, advances or any other investments to or
in the Company by any of its Subsidiaries;

         (b)     restricting the ability of any Subsidiary of the Company to
make tax payments or management fee payments to the Company; or

         (c)     restricting the ability or capacity of any Subsidiary of the
Company to make dividend payments or distributions to the Company.

title retention agreement, any obligation issued or assumed as full or partial
payment for property whether or not secured by a purchase money mortgage or any
obligation under notes payable or drafts accepted representing extensions of
credit) beyond any period of grace provided with respect thereto; or any member
of the Combined Group shall fail to perform or observe any other agreement,
term or condition contained in any agreement under which any such obligation is
created (or if any other event thereunder or under any such agreement shall
occur and be continuing) and the effect of such failure or other event is to
cause, or to permit the holder or holders of such obligation (or a trustee on
behalf of such holder or holders) to cause, such obligation to become due prior
to any stated maturity; or any member of the Combined Group shall fail to pay
any Guaranty relating to Debt for borrowed money in accordance with its terms;
provided, in each case, that the aggregate amount of all obligations as to
which such a payment default shall occur and be continuing or such a failure or
other event causing or permitting acceleration shall occur and be continuing
shall exceed $15,000,000; and provided, further that a default for purposes of
this Section 10.1(b) shall not be deemed to exist by reason of the acceleration
of the maturity of any such obligation solely by reason of a default in the
performance of a term or condition in any agreement or instrument under or by
which such obligation is created, evidenced or secured, which term or condition
restricts the right of the Company or any other Person to sell, pledge or
otherwise dispose of any margin stock (as such term is defined in Regulation U
of the Board) held by the Company or such other Person; or





                                       70
<PAGE>   76
         (c)     any representation or warranty made by the Company or any of
its officers in any Credit Document or in any other writing furnished to the
Agent or any Bank in connection with any Credit Document shall prove to have
been false or misleading in any material respect on the date as of which it was
made; or

         (d)     the Company shall default in the performance of any of its
obligations under Sections 9.6 through 9.12; or the Company shall default in
the performance of any of its obligations under Section 9.1(i) and such default
shall not be remedied within 15 days after any executive officer of the Company
obtains actual knowledge thereof; or

         (e)     the Company shall default in the performance of any of its
obligations in any Credit Document other than those specified elsewhere in this
Section 10.1 and such default shall not be remedied within 30 days after any
executive officer of the Company obtains actual knowledge thereof; or

         (f)     any member of the Combined Group shall make an assignment for
the benefit of creditors; generally fail to pay its debts as such debts become
due; or admit in writing its inability to generally pay its debts as such debts
become due; or

         (g)     a Governmental Authority shall enter any decree or order for
relief in respect of any member of the Combined Group under any bankruptcy,
reorganization, compromise, arrangement, insolvency, readjustment of debt,
dissolution or liquidation or similar law of any jurisdiction, whether now or
hereafter in effect (herein called the "Bankruptcy Law"); or

         (h)     any member of the Combined Group shall petition or apply for
or consent to the appointment of, or taking possession by, a trustee, receiver,
custodian, sequestrator, liquidator or other similar official of or for itself
or any substantial part of its assets, or shall commence a voluntary case under
any Bankruptcy Law or any proceedings (other than proceedings for the voluntary
liquidation and dissolution of a Restricted Subsidiary) relating to any member
of the Combined Group under any Bankruptcy Law; or

         (i)     any such petition or application referred to in Section
10.1(h) shall be filed, or any such proceeding referred to in Section 10.1(h)
shall be commenced, against any member of the Combined Group and such member of
the Combined Group by any act shall indicate its approval thereof, consent
thereto or acquiescence therein; or an order, judgment or decree shall be
entered appointing any such trustee, receiver, custodian, liquidator or similar
official, or approving the petition in any such proceedings, and such order,
judgment or decree shall remain unstayed and in effect for more than 60
consecutive days; or

         (j)     any order, judgment or decree shall be entered in any
proceedings against any member of the Combined Group decreeing the dissolution
or liquidation of any member of the





                                       71
<PAGE>   77
Combined Group and such order, judgment or decree shall remain unstayed and in
effect for more than the appeal time provided by law; or

         (k)     any order, judgment or decree shall be entered in any

which exceed, or the divestiture of the stock of a Restricted Subsidiary whose
assets exceed, 10% of Consolidated Net Tangible Assets as of the end of the
fiscal quarter immediately preceding or coinciding with such divestiture or (2)
the divestiture of assets or stock of a Restricted Subsidiary which shall have
contributed more than 10% of EBITDA for the four most recently completed fiscal
quarters, and such order, judgment or decree shall remain unstayed and in
effect for more than 60 consecutive days; or

         (l)     any judgment or order, or series of judgments or orders, for
the payment of money in an amount in excess of $15,000,000 shall be rendered
against any member of the Combined Group and the same shall not be discharged
(or provision shall not be made for such discharge), or a stay of execution
thereof shall not be procured, within the appeal time provided by law from the
date of entry thereof, or such member of the Combined Group shall not, within
said appeal time, or such longer period during which execution of the same
shall have been stayed, appeal therefrom and cause the execution thereof to be
stayed during such appeal; or

         (m)     the Company or any ERISA Affiliate shall fail to pay when due

incur a complete or partial withdrawal liability under Title IV of ERISA in an
annual amount in excess of $2,000,000 (and in the aggregate $15,000,000 in
connection with any Plan; or a condition shall exist by reason of which the
PBGC would be entitled to obtain a decree adjudicating that any Plan or Plans
having aggregate Unfunded Liabilities in excess of $15,000,000 must be
terminated; or there shall occur any event or condition that might reasonably
constitute grounds for the termination of any Plan or Plans having aggregate
Unfunded Liabilities in excess of $15,000,000 or with respect to such Plan or
Plans either the imposition of any liability in excess of $15,000,000 (other
than contributions in the ordinary course) or any Lien provided under Section

                                       72
<PAGE>   78
dollar threshold amounts set forth above in determining whether any such
condition or event constitutes an Event of Default under this paragraph; or

         (n)     one or more demands for payment is made upon the Company by
SFER or its successor or any other Person pursuant to the Spin-Off Tax
Indemnification Agreement and such demands exceed $15,000,000 in the aggregate;
or

         (o)     one or more demands for payment are made upon the Company by
SFER or any other Person pursuant to the Original Spin-Off Tax Indemnification
Agreement, which payments, if made, would exceed $15,000,000 in the aggregate;
or

         (p)     any Change of Control shall occur;

THEREUPON:  (I) the Agent may with the consent of the Required Banks (and, if
directed by the Required Banks, shall) do any or all of the following: (a)
declare the Commitments terminated (whereupon the Commitments shall be
terminated); (b) terminate any Letter of Credit pursuant to which such
termination is permitted; (c) declare the unpaid amount of the Loans (principal
and accrued and unpaid interest) and all Reimbursement Obligations, fees and
other amounts payable under the Credit Documents to be forthwith due and
payable, whereupon such amounts shall be and become immediately due and
payable, without notice (including notice of acceleration and notice of intent
to accelerate), presentment, demand, protest or other formalities of any kind,
all of which are hereby expressly WAIVED by the Company to the extent permitted
by law; provided that in the case of the occurrence of an Event of Default with
respect to the Company referred to in Section 10.1(g) through (i), the
Commitments shall be automatically terminated and the unpaid amount of the
Loans (principal and accrued and unpaid interest) and all Reimbursement
Obligations, fees and all other amounts payable under the Credit Documents
shall be and become automatically and immediately due and payable, without
notice (including notice of intent to accelerate and to the extent permitted by
the law, notice of acceleration) and without presentment, demand, protest or
other formalities of any kind, all of which are hereby expressly WAIVED by the
Company; and (d) require Cover for all Letter of Credit Liabilities; (II) each
Bank may exercise its rights of offset against each account and all other
property of the Company in the possession of such Bank, which right is hereby
granted by the Company to the Banks; and (III) the Agent and each Bank may
exercise any and all other rights available to them pursuant to the Credit
Documents, at law and in equity.

         Section 11.      The Agent.

         11.1.   Appointment, Powers and Immunities.  Each Bank hereby
irrevocably appoints and authorizes the Agent to act as its agent under the
Credit Documents with such powers as are specifically delegated to the Agent by
the terms thereof, together with such other powers as are reasonably incidental
thereto.  The Agent (which term as used in this Section 11 shall include





                                       73
<PAGE>   79
reference to its Affiliates and its own and its Affiliates' officers,
directors, employees and agents) (a) shall have no duties or responsibilities
except those expressly set forth in the Credit Documents and shall not by
reason of any Credit Document be a trustee or fiduciary for any Bank; (b) shall
not be responsible to any Bank for any recitals, statements, representations or
warranties contained in any Credit Document, or in any certificate or other
document referred to or provided for in, or received by any of them under, any
Credit Document, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of any Credit Document or any other document
referred to or provided for therein or any property covered thereby or for any
failure by the Company or any other Person to perform any of its obligations
thereunder; (c) shall not be required to initiate or conduct any enforcement,
litigation or collection proceedings hereunder or under any Credit Document
except to the extent requested by the Required Banks (and Section 11.7 shall
apply), and (d) SHALL NOT BE RESPONSIBLE TO ANY BANK FOR ANY ACTION taken or
omitted to be taken by it under any Credit Document or any other document or
instrument referred to or provided for therein or in connection therewith,
INCLUDING ANY SUCH ACTION PURSUANT TO ITS OWN NEGLIGENCE, except for its own
gross negligence or willful misconduct.  The Agent may employ agents and
attorneys-in-fact and shall not be responsible for the negligence or misconduct
of any such agents or attorneys-in-fact selected by it with reasonable care.
Without in any way limiting any of the foregoing, each Bank acknowledges that
the Agent shall have no greater responsibility in the operation of the Letters
of Credit than is specified in the Uniform Customs and Practice of Documentary
Credits (1993 Revision, International Chamber of Commerce Publication No. 500).

         11.2.   Reliance by Agent.  The Agent shall be entitled to rely upon
any certification, notice or other communication (including any thereof by
telephone, facsimile, telegram or cable) believed by it to be genuine and
correct and to have been signed or sent by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel (which may be counsel
for the Company), independent accountants and other experts selected by the
Agent.  As to any matters not expressly provided for by any Credit Document,
the Agent shall in all cases be fully protected in acting, or in refraining
from acting, in accordance with instructions of the Required Banks, and any
action taken or failure to act pursuant thereto shall be binding on all of the
Banks.

         11.3.   Defaults.  The Agent shall not be deemed to have knowledge of
the occurrence of a Default (other than the nonpayment of Loans, Reimbursement
Obligations, Commitment Fee or Letter of Credit Fee) unless it has received
notice from a Bank or the Company specifying such Default and stating that such
notice is a "Notice of Default".  In the event that the Agent receives such a
notice of the occurrence of a Default, the Agent shall give prompt notice
thereof to the Banks (and shall give each Bank prompt notice of each such
nonpayment).  The Agent shall (subject to Sections 11.7 and 12.5) take such
action with respect to such Default as shall be directed by all Banks or the
Required Banks, as appropriate, and within its rights under the Credit
Documents and at law or in equity; provided that, unless and until the Agent
shall have received such directions, the Agent may with the consent of the
Required Banks (but shall not be obligated to) take such action, or refrain
from taking such action, permitted hereby with respect to such Default as it
shall deem





                                       74
<PAGE>   80
advisable in the best interests of the Banks and within its rights under the
Credit Documents, at law or in equity, and shall be fully protected in doing
so.

         11.4.   Rights as a Bank.  With respect to its Commitment, Loans and
Letter of Credit Liabilities, Chase in its capacity as a Bank hereunder shall
have the same rights and powers under the Credit Documents as any other Bank
and may exercise the same as though it were not acting as the Agent, and the
term "Bank" or "Banks" shall, unless the context otherwise indicates, include
the Agent in its individual capacity.  The Agent may (without having to account
therefor to any Bank) accept deposits from, lend money to and generally engage
in any kind of banking, trust, letter of credit, agency or other business with
the Company (and any of its Affiliates) as if it were not acting as the Agent,
and the Agent may accept fees and other consideration from the Company and its
Affiliates (in addition to the fees heretofore agreed to between the Company
and the Agent) for services in connection with this Agreement or otherwise
without having to account for the same to the Banks.  Without limiting the
rights and remedies of the Banks specifically set forth herein, no other Bank
by virtue of being a Bank hereunder shall have any interest in any such
activities, any present or future guaranty by or for the account of the
Company, any present or future offset exercised by the Agent in respect of any
such other activities, or any present or future property at any time taken as
security for any such other activities; provided, however, that if any payment
in respect of such guaranties or such property or the proceeds thereof shall be
applied to the Obligations, each Bank shall be entitled to share in such
application pro rata according to its portion of the Obligations.

         11.5.   INDEMNIFICATION.  THE BANKS SHALL INDEMNIFY THE AGENT AND EACH
OTHER INDEMNIFIED PERSON (TO THE EXTENT NOT REIMBURSED UNDER SECTION 12.3 OR
12.4, BUT WITHOUT LIMITING THE OBLIGATIONS OF THE COMPANY UNDER SAID SECTIONS
12.3 AND 12.4), RATABLY IN ACCORDANCE WITH THEIR RESPECTIVE COMMITMENT
PERCENTAGES, FOR ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND DISBURSEMENTS OF ANY
KIND AND NATURE WHATSOEVER (INCLUDING THE CONSEQUENCES OF THE NEGLIGENCE OF THE
AGENT OR ANY OTHER INDEMNIFIED PERSON) WHICH MAY BE IMPOSED ON, INCURRED BY OR
ASSERTED AGAINST THE AGENT OR ANY INDEMNIFIED PERSON IN ANY WAY RELATING TO OR
ARISING OUT OF ANY CREDIT DOCUMENT (AS DEFINED HEREIN) OR ANY OTHER DOCUMENTS
CONTEMPLATED BY OR REFERRED TO THEREIN OR THE TRANSACTIONS CONTEMPLATED BY ANY
CREDIT DOCUMENT (INCLUDING THE COSTS AND EXPENSES WHICH THE COMPANY IS
OBLIGATED TO PAY UNDER SECTIONS 12.3 AND 12.4 BUT EXCLUDING, UNLESS A DEFAULT
OR A BORROWING BASE DEFICIENCY HAS OCCURRED AND IS CONTINUING, NORMAL
ADMINISTRATIVE COSTS AND EXPENSES INCIDENT TO THE PERFORMANCE OF ITS DUTIES
UNDER THE CREDIT DOCUMENT) OR THE ENFORCEMENT OF ANY OF THE TERMS OF ANY CREDIT
DOCUMENT OR OF ANY SUCH OTHER DOCUMENTS; PROVIDED





                                       75
<PAGE>   81
THAT NO BANK SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE EXTENT THEY ARISE
FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PARTY TO BE INDEMNIFIED.
The obligations of the Banks under this Section 11.5 shall survive the
termination of this Agreement.

         11.6.   Non-Reliance on the Agent and Other Banks.  Each Bank agrees
that it has received current financial information with respect to the Company
and its Subsidiaries and that it has, independently and without reliance on the
Agent or any other Bank and based on such documents and information as it has
deemed appropriate, made its own credit analysis of the Company and decision to
enter into this Agreement and that it will, independently and without reliance
upon the Agent or any other Bank, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under the Credit Documents.  The Agent
shall not be required to keep itself informed as to the performance or
observance by the Company of any Credit Document or any other document referred
to or provided for therein or to inspect the property or books of the Company
or any other Person.  Except for notices, reports and other documents and
information expressly required to be furnished to the Banks by the Agent under
the Credit Documents, the Agent shall not have any duty or responsibility to
provide any Bank with any credit or other information concerning the affairs,
financial condition or business of the Company (or any of its Affiliates) which
may come into the possession of the Agent.

         11.7.   Failure to Act.  Except for action expressly required of the
Agent under the Credit Documents, the Agent shall in all cases be fully
justified in failing or refusing to act under the Credit Documents unless it
shall have received further assurances to its satisfaction by the Banks of
their indemnification obligations under Section 11.5 against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action.

         11.8.   Resignation or Removal of the Agent.  Subject to the
appointment and acceptance of a successor Agent as provided below, the Agent
may resign at any time by giving notice thereof to the Banks and the Company,
and the Agent may be removed at any time with or without cause by the Required
Banks.  Upon any such resignation or removal, the Required Banks shall have the
right to appoint a successor Agent.  If no successor Agent shall have been so
appointed by the Required Banks and shall have accepted such appointment within
30 days after the retiring Agent's giving of notice of resignation or the
Required Banks' removal of the retiring Agent, the retiring Agent may, on
behalf of the Banks, appoint a successor Agent.  Any successor Agent shall be a
bank which has an office in the United States and a combined capital and
surplus of at least $250,000,000 and with its deposits insured by the FDIC.
Upon the acceptance of any such appointment, the successor Agent shall succeed
to and become vested with all the rights, powers, privileges and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations under the Credit Documents.  Such successor Agent shall promptly
specify its Principal Office referred to in Sections 3.1 and 5.1 by notice to
the Company and the Banks.  After any retiring Agent's





                                       76
<PAGE>   82
resignation or removal hereunder as the Agent, the provisions of this Section
11 shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as the Agent.

         11.9.   WAIVER.  THE BANKS CONSENT TO CHASE'S SERVING AS AGENT UNDER
THE CREDIT AGREEMENT DATED AS OF NOVEMBER 13, 1996, BY AND AMONG SANTA FE
ENERGY RESOURCES, INC., THE FINANCIAL INSTITUTIONS PARTY THERETO AND CHASE AS
THE AGENT, AS AMENDED, MODIFIED, SUPPLEMENTED AND RESTATED AND FROM TIME TO
TIME IN EFFECT (THE "SANTA FE CREDIT AGREEMENT"), WAIVE ANY CONFLICT OF
INTEREST IN CONNECTION THEREWITH, AND AGREE THAT CHASE MAY MAKE DECISIONS AND
DETERMINATIONS AND MAY EXERCISE OR REFRAIN FROM EXERCISING ITS RIGHTS AND
REMEDIES AS THE AGENT UNDER THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND
UNDER THE SANTA FE CREDIT AGREEMENT (AND THE AGREEMENTS IN CONNECTION
THEREWITH), AND AT LAW, ALL AS CHASE MAY IN ITS SOLE DISCRETION (WHICH MAY BE
EXERCISED ARBITRARILY) FROM TIME TO TIME DEEM APPROPRIATE.

         Section 12.      Miscellaneous.

         12.1.   Waiver.  No waiver of any Default shall be a waiver of any
other Default.  No failure on the part of the Agent or any Bank to exercise and
no delay in exercising, and no course of dealing with respect to, any right,
power or privilege under any Credit Document shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, power or privilege
thereunder preclude any other or further exercise thereof or the exercise of
any other right, power or privilege.  The remedies provided in the Credit
Documents are cumulative and not exclusive of any remedies provided by law or
in equity.

         12.2.   Notices.  All notices and other communications provided for in
the Credit Documents (including any modifications of, or waivers or consents
under, this Agreement) shall be in writing and (a) delivered against receipt
therefor, (b) sent by overnight courier (such as Federal Express), charges
prepaid, (c) mailed by registered or certified mail, return receipt requested,
postage prepaid, or (d) given or made by telegraph, telecopy (confirmed by
mail), cable or other writing, in each case addressed to the intended recipient
at the "Address for Notices" specified below its name on the signature pages
hereof; or, as to any party, at such other address as shall be designated by
such party in a notice to the Company and the Agent given in accordance with
this Section 12.2.   Except as otherwise provided in this Agreement, all such
communications shall be deemed to have been duly given when delivered; on the
Business Day following delivery to an overnight courier; when transmitted
before 5 p.m. on a Business Day by telecopier or delivered to the telegraph or
cable office (when transmitted after 5 p.m. on a Business Day, at 9 a.m. on the
next Business Day); or on the second Business Day after its deposit in the
mails; provided, however, that notices required or

Agent.  Actual notice shall always be effective.

         12.3.   Expenses.  Whether or not any Loan is ever made or any Letter

         12.4.   INDEMNIFICATION.

         (I)     TO THE FULLEST EXTENT PERMITTED BY LAW, THE COMPANY SHALL
INDEMNIFY THE AGENT (INCLUDING THE AGENT WHEN ACTING AS ISSUER OF LETTERS OF
CREDIT), EACH BANK AND EACH OTHER INDEMNIFIED PERSON FROM, AND HOLD EACH OF
THEM HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, COSTS, EXPENSES, CLAIMS
OR DAMAGES TO WHICH ANY OF THEM MAY BECOME SUBJECT, REGARDLESS OF AND INCLUDING
LOSSES, LIABILITIES, COSTS, EXPENSES, CLAIMS AND DAMAGES ARISING FROM THE
NEGLIGENCE OF THE AGENT OR THE BANKS OR ANY OTHER INDEMNIFIED PERSON, INSOFAR
AS SUCH LOSSES, LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES ARISE OUT OF OR
IN CONNECTION WITH (A) ANY ACTUAL OR PROPOSED USE BY THE COMPANY OF THE
PROCEEDS OF ANY EXTENSION OF CREDIT UNDER THIS AGREEMENT; (B) ANY BREACH BY THE
COMPANY OF ANY CREDIT DOCUMENT (AS DEFINED HEREIN); (C) ANY VIOLATION BY THE
COMPANY OR ANY OF ITS SUBSIDIARIES OF ANY LEGAL REQUIREMENT, INCLUDING, WITHOUT
LIMITATION, APPLICABLE ENVIRONMENTAL LAWS; (D) ANY ENVIRONMENTAL CLAIMS OR (E)
ANY INVESTIGATION, LITIGATION OR OTHER PROCEEDING (INCLUDING ANY THREATENED
INVESTIGATION OR PROCEEDING) RELATING TO ANY OF THE FOREGOING, AND THE COMPANY
SHALL REIMBURSE EACH INDEMNIFIED PERSON, UPON DEMAND, FOR ANY EXPENSES
(INCLUDING REASONABLE LEGAL FEES) INCURRED IN CONNECTION





                                       78
<PAGE>   84
WITH ANY SUCH INVESTIGATION OR PROCEEDING; BUT EXCLUDING ANY SUCH LOSSES,
LIABILITIES, CLAIMS, DAMAGES, COSTS OR EXPENSES INCURRED BY SUCH INDEMNIFIED
PERSON BY REASON OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY
INDEMNIFIED PERSON.

         (II)    TO THE FULLEST EXTENT PERMITTED BY LAW, THE COMPANY SHALL
INDEMNIFY THE AGENT (INCLUDING THE AGENT WHEN ACTING AS ISSUER OF LETTERS OF
CREDIT), AND EACH OTHER INDEMNIFIED PERSON FROM, AND HOLD EACH OF THEM HARMLESS
AGAINST, ANY AND ALL LOSSES, LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES TO
WHICH ANY OF THEM MAY BECOME SUBJECT, REGARDLESS OF AND INCLUDING LOSSES,
LIABILITIES, COSTS, EXPENSES, CLAIMS AND DAMAGES ARISING FROM THE NEGLIGENCE OF
THE AGENT OR THE BANKS OR ANY OTHER INDEMNIFIED PERSON, IN CONNECTION WITH THE
EXECUTION AND DELIVERY OR TRANSFER OF OR PAYMENT OR FAILURE TO PAY UNDER ANY
LETTER OF CREDIT, INCLUDING, WITHOUT LIMITATION, ANY CLAIMS, DAMAGES, LOSSES,
LIABILITIES, COSTS OR EXPENSES WHICH THE AGENT, OR SUCH OTHER INDEMNIFIED
PERSON, AS THE CASE MAY BE, MAY INCUR (WHETHER INCURRED AS A RESULT OF ITS OWN
NEGLIGENCE OR OTHERWISE) BY REASON OF OR IN CONNECTION WITH THE FAILURE OF ANY
OTHER BANK (WHETHER AS A RESULT OF ITS OWN NEGLIGENCE OR OTHERWISE) TO FULFILL
OR COMPLY WITH ITS OBLIGATIONS TO THE AGENT OR ANY BANK, AS THE CASE MAY BE,
WITH RESPECT TO SUCH LETTER OF CREDIT HEREUNDER (BUT NOTHING HEREIN CONTAINED
SHALL AFFECT THE RIGHTS THE COMPANY MAY HAVE AGAINST SUCH DEFAULTING BANK); BUT
EXCLUDING ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES, COSTS OR EXPENSES
INCURRED BY SUCH INDEMNIFIED PERSON BY REASON OF THE GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT OF ANY INDEMNIFIED PERSON.

         (III)   The obligation of the Company to provide indemnification under
this Section 12.4 for fees and expenses of counsel shall be limited to the
reasonable fees and expenses of one counsel in each jurisdiction representing
all of the Persons entitled to such indemnification, except to the extent that,
in the reasonable judgment of any such Indemnified Person, the existence of
actual or potential conflicts of interest make representation of all of such
indemnified Persons by the same counsel inappropriate; in such a case, the
Person exercising such judgment shall be indemnified for the reasonable fees
and expenses of its separate counsel to the extent provided in this Section
12.4 without giving effect to the first clause of this sentence.  Nothing in
this Section 12.4 is intended to limit the obligations of the Company under any
other provision of this Agreement.

         12.5.   Amendments, Etc.  No amendment or waiver (including any waiver
of any condition precedent to the issuance of any Letter of Credit set forth in
Section 7.2) of any provision of any





                                       79
<PAGE>   85
Credit Document, nor any consent to any departure by the Company therefrom,
shall in any event be effective unless the same shall be agreed or consented to
by the Required Banks and the Company, as appropriate, and each such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given; provided that no amendment, waiver or consent shall,
unless in writing and signed by each Bank affected thereby, do any of the
following: (a) increase the Commitment of any of the Banks or subject any Bank
to any additional obligation; (b) reduce the principal of, or interest on, any
Loan, Reimbursement Obligation, fee or other sum to be paid under any Credit
Document; (c) postpone any scheduled date fixed for any payment of principal
of, or interest on, any Loan, Reimbursement Obligation, fee or other sum to be
paid under any Credit Document; (d) change the percentage of the Aggregate
Commitment, or of the aggregate unpaid principal amount of any of the Loans, or
the number of Banks, which shall be required for the Banks or any of them to
take any action under this Agreement or any other Credit Document; or (e)
change any provision contained in Sections 2.3, 5.2, 5.7, 6, 12.3 or 12.4 or
this Section 12.5.   Anything in this Section 12.5 to the contrary, no
amendment, waiver or consent shall be made with respect to Section 11 without
the consent of the Agent.

         12.6.   Successors and Assigns.

         (a)     This Agreement and the other Credit Documents shall be binding
upon and inure to the benefit of the Company, the Agent and the Banks and their
respective successors and assigns.  The Company may not assign or transfer any
of its rights or obligations under any of the Credit Documents without the
prior written consent of all of the Banks.

         (b)     Each Bank may sell participations to any Person in all or part
of its Loans, Reimbursement Obligations, Note and Commitment, in which event,
without limiting the foregoing, the provisions of Section 6 shall inure to the
benefit of each purchaser of a participation (but any recovery upon the
occurrence of any of the events or circumstances described in Section 6 by any
purchaser of a participation on account of such participation shall be limited
to such purchaser's share (pro rata according to the ratio of the
participations held by such purchaser and Loans, Reimbursement Obligations,
Note and Commitment sold to other purchasers or retained by the selling Bank)
of any recovery achieved by such purchaser's transferor Bank upon the
occurrence of such events or circumstances) and the pro rata treatment of
payments, as described in Section 5.2, shall be determined as if such Bank had
not sold such participation.  In the event any Bank shall sell any
participation, (1) the Company, the Agent and the other Banks shall continue to
deal solely and directly with such selling Bank in connection with such selling
Bank's rights and obligations under the Credit Documents (including the Note
held by such selling Bank); (2) such Bank shall retain the sole right and
responsibility to enforce the obligations of the Company under the Credit
Documents, including the right to approve any amendment, modification or waiver
of any provision of this Agreement or any other Credit Document other than
amendments, modifications or waivers with respect to (A) any fees payable
hereunder to the Banks and (B) the amount of principal or the rate of interest
payable on, or the dates fixed for the scheduled repayment of principal of, the
Loans,





                                       80
<PAGE>   86
Reimbursement Obligations and other sums to be paid to the Banks under the
Credit Documents, and (3) the Company agrees, to the fullest extent it may
effectively do so under applicable law, that any participant of a Bank may
exercise all rights of set-off, bankers' lien, counterclaim or similar rights
with respect to such participation as fully as if such participant were a
direct holder of Loans and Reimbursement Obligations if such Bank has
previously given notice of the sale of such participation to the Company.

         (c)     Each Bank may assign to one or more Banks or Eligible
Assignees all or a portion of its interests, rights and obligations under this
Agreement and the other Credit Documents (including all or a portion of its
Commitment and the same portion of the Loans and Letter of Credit Advances at
the time owing to it and of its outstanding Letter of Credit Liabilities at the
time and the Note held by it); provided that (1) other than in the case of an
assignment to a Person at least 50% owned by the assignor Bank, or by a common
parent of both, or to another Bank, the Agent and the Company must give their
respective prior written consent, which consent will not be unreasonably
withheld; (2) the aggregate amount of the Commitment, Loans and outstanding
Letter of Credit Liabilities of the assigning Bank subject to each such
assignment (determined as of the date the Assignment Agreement with respect to
such assignment is delivered to the Agent) shall in no event be less than
$10,000,000 (or $1,000,000 in the case of an assignment between Banks) (except
for certain exceptions approved by the Company and the Agent or where all of a
Bank's Commitment, Loans and outstanding Letter of Credit Liabilities are being
assigned) and shall be in an amount that is an integral multiple of $1,000,000
(except for certain exceptions approved by the Company and the Agent or where
all of a Bank's Commitment, Loans and outstanding Letter of Credit Liabilities
are being assigned); and (3) the parties to each such assignment shall execute
and deliver to the Agent, for its acceptance and recording in its records, an
Assignment Agreement with blanks appropriately completed, together with the
Note subject to such assignment and a processing and recordation fee of $2,500
(for which the Company shall have no liability except in the case of
assignments required by the Company pursuant to Section 6.1, 6.3, 6.6 or 6.7,
in which case such fee shall be paid by the Company).  Upon such execution,
delivery, acceptance and recording, from and after the effective date specified
in each Assignment Agreement, which shall be at least five Business Days after
the date of execution thereof (unless otherwise agreed by the parties thereto
and the Agent), (A) the assignee thereunder shall be a party to this Agreement
and, to the extent provided in such Assignment Agreement, have the rights and
obligations of a Bank under the Credit Documents, and (B) the Bank making such
assignment shall, to the extent provided in such Assignment Agreement, be
released from its obligations under this Agreement and the other Credit
Documents (and, in the case of an Assignment Agreement covering all or the
remaining portion of an assigning Bank's rights and obligations under this
Agreement, such Bank shall cease to be a party hereto) but shall be entitled to
the benefit of this Agreement and the other Credit Documents for matters
occurring during the time it was a Bank under this Agreement.

         (d)     By executing and delivering an Assignment Agreement, the
assigning Bank and the assignee thereunder confirm to and agree with each other
and the other parties to this Agreement as





                                       81
<PAGE>   87
follows:  (1) other than the representation and warranty that it is the legal
and beneficial owner of the interest being assigned thereby free and clear of
any adverse claim, such assigning Bank makes no representation or warranty and
assumes no responsibility with respect to any statements, warranties or
representations made in or in connection with any Credit Document or the
execution, legality, validity, enforceability, genuineness, sufficiency or
value of any Credit Document; (2) such assigning Bank makes no representation
or warranty and assumes no responsibility with respect to the financial
condition of the Company or the performance or observance by the Company of any
of its obligations under any Credit Document; (3) such assignee confirms that
it has received a copy of this Agreement, together with copies of the financial
statements of the Company previously delivered by the Company in accordance
herewith and such other documents and information as it has deemed appropriate
to make its own credit analysis and decision to enter into such Assignment
Agreement; (4) such assignee will, independently and without reliance upon the
Agent, such assigning Bank or any other Bank and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under the Credit Documents; (5)
such assignee appoints and authorizes the Agent to take such action as agent on
its behalf and to exercise such powers under the Credit Documents as are
delegated to the Agent by the terms hereof, together with such powers as are
reasonably incidental thereto, and (6) such assignee agrees that it will
perform in accordance with their terms all obligations that by the terms of the
Credit Documents are required to be performed by it as a Bank.

         (e)     The Agent shall maintain at its office a copy of each
Assignment Agreement delivered to it and a record of the names and addresses of
the Banks and the Commitment of, and the principal amount of the Loans and
Letter of Credit Advances owing to, and the outstanding Letter of Credit
Liabilities of, each Bank from time to time.  The entries in such record shall
be conclusive, in the absence of manifest error, and the Company, the Agent and
the Banks may treat each Person the name of which is recorded therein as a Bank
hereunder for all purposes of the Credit Documents.  Such records shall be
available for inspection by the Company or any Bank at any reasonable time and
from time to time upon reasonable prior notice.

         (f)     Upon its receipt of an Assignment Agreement executed by an
assigning Bank and the assignee thereunder together with the Note subject to
such assignment, any required consent to such assignment and the fee payable in
respect thereto, the Agent shall, if such Assignment Agreement has been
completed with blanks appropriately filled, (1) accept such Assignment
Agreement; (2) record the information contained therein in its records, and (3)
give prompt notice thereof to the Company.  Contemporaneously with the receipt
by the Agent of an Assignment Agreement, the Company, at its own expense, shall
execute and deliver to the Agent in exchange for each surrendered Note a new
Note payable to the order of such assignee in an amount equal to the Commitment
and/or Loans assumed by it pursuant to such Assignment Agreement and, if the
assigning Bank has retained any Commitment and/or Loans hereunder, a new Note
payable to the order of the assignor Bank in an amount equal to the Commitment
and/or Loans retained by it.  Such new Notes shall be in an aggregate face
amount equal to the face amount of each surrendered Note,





                                       82
<PAGE>   88
shall be dated the effective date of such Assignment Agreement and shall
otherwise be in substantially the form of the surrendered Note.  Thereafter,
the surrendered Note shall be marked canceled and returned to the Company.

         (g)     Any Bank may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
12.6, disclose to the assignee or participant or proposed assignee or
participant any information relating to the Company furnished to such Bank by
or on behalf of the Company.

         (h)     Notwithstanding anything herein to the contrary, each Bank may
pledge and assign all or any portion of its rights and interests under the
Credit Documents to any Federal Reserve Bank.  No such assignment shall release
the assigning Bank from its obligations hereunder.

         (i)     All transfers of any interest in any Note hereunder shall be
in compliance with all federal and state securities laws, if applicable.
Notwithstanding the foregoing sentence, however, the parties to this Agreement
do not intend that any transfer under this Section 12.6 be construed as a
"purchase" or "sale" of a "security" within the meaning of any applicable
federal or state securities laws.

         (j)     Notwithstanding any other provision of this Section 12.6
(except subsection (h)), Chase and its Affiliates may not make any assignment
of their rights hereunder which would reduce their aggregate Commitment
Percentages below 10%.

         12.7.   Survival; Termination; Reinstatement.

         (a)     In addition to the other provisions of the Credit Documents
expressly stated to survive the termination of this Agreement, the obligations
of the Company under Sections 6, 12.3 and 12.4 and the last sentence of this
Section 12.7 and the obligations of the Banks under Sections 11.5, 12.8 and
12.12 shall survive the termination of this Agreement.

         (b)     This Agreement shall terminate upon (i) the full and final
payment of all Notes and Reimbursement Obligations, (ii) the expiry of all
Letters of Credit, (iii) the termination of all Commitments and (iv) the
payment of all non-contingent amounts due under the Credit Documents.
Notwithstanding the foregoing, if all conditions to the termination of this
Agreement set forth in this Section 12.7(b) shall have been satisfied other
than the expiry of all Letters of Credit, and all outstanding Letters of Credit
shall have been fully Covered or shall be backed by a letter of credit in
Proper Form issued by an issuer acceptable to the Issuer in its sole
discretion, the Company shall in such event no longer be required to comply
with Section 9.

         (c)     If at any time all or any part of any payment previously
applied by the Agent or any Bank to any Loan, Reimbursement Obligation or other
sum hereunder is or must be returned by or





                                       83
<PAGE>   89
recovered from the Agent or such Bank for any reason (including the order of
any bankruptcy court), to the extent permitted by law, the Credit Documents
shall automatically be reinstated to the same effect as if such prior
application had not been made, and the Company shall indemnify the Agent or
such Bank against, and save and hold the Agent and such Bank harmless from, any
required return by or recovery from the Agent or such Bank of any such payment
because of its being deemed preferential under any applicable Legal Requirement
or for any other reason.

         12.8.   Limitation of Interest.  The parties to the Credit Documents
intend to strictly comply with all applicable laws, including applicable usury
laws.  Accordingly, the provisions of this Section 12.8 shall govern and
control over every other provision of any Credit Document which conflicts or is
inconsistent with this Section 12.8, even if such provision declares that it
controls. To the maximum extent permitted by applicable law, (a) any
non-principal payment shall be characterized as an expense or as compensation
for something other than the use, forbearance or detention of money and not as
interest and (b) all interest at any time contracted for, taken, reserved,
retained, charged or received shall be amortized, prorated, allocated and
spread, in equal parts, during the full term of the Loans and the Commitments.
In no event shall the Company or any other Person be obligated to pay, or the
Agent or any Bank have any right or privilege to reserve, take, receive or
retain, any interest in excess of the maximum amount of nonusurious interest
permitted under applicable law.  If the term of any of the Notes is shortened
by reason of acceleration of maturity as a result of any Default or by any
other cause, or by reason of any required or permitted prepayment, and if for
that (or any other) reason the Agent or any Bank at any time, including the
stated maturity, is owed or receives (and/or has reserved, taken or received)
interest in excess of interest calculated at the Highest Lawful Rate, then and
in any such event all of any such excess interest shall be canceled
automatically as of the date of such acceleration, prepayment or other event
which produces the excess, and, if such excess interest has been paid to the
Agent or such Bank, it shall be credited pro tanto against the then-outstanding
principal balance of the Company's obligations to the Agent or such Bank,
effective as of the date or dates when the event occurs which causes it to be
excess interest, until such excess is exhausted or all of such principal has
been fully paid and satisfied, whichever occurs first, and any remaining
balance of such excess shall be promptly refunded to its payor.

         12.9.   Captions.  Captions and section headings appearing in the
Credit Documents are included solely for convenience and shall not be
considered in construing the Credit Documents.

         12.10.  Counterparts.  Each Credit Document may be executed in any
number of identical counterparts, and by the parties on separate counterparts,
and each counterpart, when so executed and delivered, shall constitute an
original instrument, and all such separate counterparts together shall
constitute but one and the same agreement.

RECEIVE, ACCEPT AND ACKNOWLEDGE FOR AND ON ITS BEHALF, AND IN RESPECT OF ITS
PROPERTY, SERVICE OF ANY AND ALL LEGAL PROCESS, SUMMONSES, NOTICES AND
DOCUMENTS WHICH MAY BE SERVED IN ANY SUCH ACTION OR PROCEEDING.  IF FOR ANY
REASON SUCH DESIGNEE, APPOINTEE AND AGENT SHALL CEASE TO BE AVAILABLE TO ACT AS

THE COMPANY AGREES TO DESIGNATE A NEW DESIGNEE, APPOINTEE AND AGENT IN THE
STATE OF NEW YORK ON THE TERMS AND FOR THE PURPOSES OF THIS PROVISION
SATISFACTORY TO THE AGENT UNDER THIS AGREEMENT.  THE COMPANY FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT OF ANY OF THE AFOREMENTIONED
COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY
REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO THE COMPANY AT ITS ADDRESS
SET FORTH OPPOSITE ITS SIGNATURE BELOW, SUCH SERVICE TO BECOME EFFECTIVE TEN
DAYS AFTER SUCH MAILING.  NOTHING IN THIS AGREEMENT SHALL AFFECT THE RIGHT OF
THE AGENT, ANY BANK OR THE HOLDER OF ANY NOTE TO SERVE PROCESS IN ANY OTHER
MANNER PERMITTED BY LAW OR TO THE EXTENT PERMITTED BY LAW TO COMMENCE LEGAL
PROCEEDINGS OR OTHERWISE TO PROCEED AGAINST THE COMPANY IN ANY OTHER

WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM
ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER CREDIT DOCUMENTS OR THE
TRANSACTIONS CONTEMPLATED BY ANY CREDIT DOCUMENT.

         12.12.  Confidentiality.  Each Bank agrees to exercise its best
efforts to keep any information delivered or made available by the Company to
it (including any information obtained pursuant to Section 9.1) which is
clearly indicated to be confidential information, confidential from anyone
other than Persons employed or retained by such Bank who are or are expected to
become engaged in evaluating, approving, structuring or administering the Loans
or the Letters of Credit; provided that nothing herein shall prevent any Bank
from disclosing such information (a) to any other Bank, (b) pursuant to
subpoena or upon the order of any court or administrative agency, (c) upon the
request or demand of any regulatory agency or authority having jurisdiction
over such Bank, (d) which has been publicly disclosed, (e) to the extent
reasonably required in connection with any litigation to which the Agent, any
Bank, or their respective Affiliates may be a party, (f) to the extent

Company of any information that it is required or requested to deliver pursuant
to clause (b) or (c) (other than, with respect to clause (c) only, in
connection with a regulatory review in the ordinary course of business) of this
Section 12.12 and, if the Company is not a party to any such litigation, clause
(e) of this Section 12.12.

         12.13.  Entire Agreement.  This Agreement and the other Credit
Documents embody the entire agreement among the parties with respect to their
subject matter and supersede all prior proposals, agreements and understandings
related to the subject matter of this Agreement and the other Credit Documents.

         12.14.  Construction.  The parties agree that this Agreement and the
other Credit Documents were negotiated agreements and accordingly no
presumption shall attach based on the identity of the drafting party.

         12.15.  Severability.  Whenever possible, each provision of the Credit
Documents shall be interpreted in such manner as to be effective and valid
under applicable law.  If any provision of any





                                       86
<PAGE>   92
Credit Document shall be invalid, illegal or unenforceable in any respect under
any applicable law, the validity, legality and enforceability of the remaining
provisions of such Credit Document shall not be affected or impaired thereby.

         12.16.  Release.  The Company hereby RELEASES, DISCHARGES AND ACQUITS
FOREVER the Agent, the Banks and their respective officers, directors,
trustees, agents, employees and counsel (in each case, past, present or future)

execution hereof by the applicable person or entity, if later).  As used
herein, the term "Claim" shall mean any and all liabilities, claims, defenses,
demands, actions, causes of action, judgments, deficiencies, interest, liens,
costs or expenses (including court costs, penalties, attorneys' fees and
disbursements and amounts paid in settlement) of any kind and character
whatsoever, including claims for usury, breach of contract, breach of
commitment, negligent misrepresentation or failure to act in good faith, in
each case whether now known or unknown, suspected or unsuspected, asserted or
unasserted or primary or contingent, and whether arising out of written
documents, unwritten undertakings, course of conduct, tort, violations of laws
or regulations or otherwise in each case to the extent, but only to the extent,
such matters relate to the Credit Documents or any of the other documents,
instruments and other agreements described in this Agreement or any related
document, instrument or agreement to any of the foregoing and the transactions
evidenced and contemplated by any of the foregoing.

         12.17.  Existing Credit Facility Terminated.  By their execution and
delivery hereof, the Company and the other parties to the Existing Credit
Facility terminate the Existing Credit Facility (except for the portions
thereof which are stated therein to survive the termination thereof).
