of the

                                     II-1

corporation and certain other persons serving at the request of the corporation
in related capacities against amounts paid and expenses incurred in connection
with an action or proceeding to which he is or is threatened to be made a party
by reason of such position, if such person shall have acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, in any criminal proceeding, if such person
had no reasonable cause to believe his conduct was unlawful; provided that, in
the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such

for the indemnification by the Registrant of current and former directors,

ITEM 9. UNDERTAKINGS.

                 The undersigned Registrant hereby undertakes:

                 (1)      To file, during any period in which offers or sales
are being made, a post-effective amendment to this Registration Statement:

                 (i)      To include any prospectus required by Section
10(a)(3) of the Securities Act of 1933;

                 (ii)     To reflect in the prospectus any facts or events
arising after the effective date of this Registration Statement (or the most
recent post-effective amendment hereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
Registration Statement. Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities
offered would not exceed that which was registered) and any

                                      II-4
<PAGE>   6
deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Securities and Exchange
Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
and price represent no more than a 20% change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in the effective
registration statement; and

                 (iii)    To include any material information with respect to
the plan of distribution not previously disclosed in this Registration
Statement or any material change to such information in this Registration
Statement;

         Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if
the registration statement is on Form S-3, Form S-8 or Form F-3 and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Securities and Exchange Commission by the Registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in this Registration Statement.

                 (2)      That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
herein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                 (3)      To remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold at the termination of the offering.

                 The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, each
filing of the Registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934) that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

                 Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933 and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer
or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by the final
adjudication of such issue.

                 CREDIT AGREEMENT, dated as of November 5, 1997, among The
Meridian Resource Corporation, a Texas corporation (the "Borrower"), the
several banks, financial institutions and other entities from time to time
parties to this Agreement (collectively, the "Lenders") and The Chase Manhattan
Bank, as administrative agent for the Lenders (in such capacity, the
"Administrative Agent").


                              W I T N E S S E T H:

                 WHEREAS, the Borrower, C. Acquisition Corp., a wholly-owned
subsidiary of the Borrower, and Cairn Energy USA, Inc. ("Cairn"), have entered
into an Agreement and Plan of Merger, dated July 3, 1997 (the "Merger
Agreement");

                 WHEREAS, as contemplated by the Merger Agreement, C.
Acquisition Corp., simultaneously with the making of the initial Loans (such
term and each other capitalized term used but not defined in these recitals
having the meaning given to it in Section 1), shall merge with and into Cairn
(the "Merger") and each outstanding share of Cairn common stock will be
converted into the right to receive 1.08 shares of the Borrower's common stock,
whereupon Cairn will become a wholly-owned subsidiary of the Borrower;

                 WHEREAS, the proceeds of the Loans are to be used to refinance
indebtedness of the Borrower and its Subsidiaries (including Cairn and its
Subsidiaries) upon consummation of the Merger, to pay fees and expenses related
to the Merger and for working capital and for the general corporate purposes of
the Borrower and its Subsidiaries in the ordinary course of business;

                 WHEREAS, the Borrower has requested the Issuing Lender to
issue Letters of Credit to support payment obligations incurred in the ordinary
course of business;

                 NOW THEREFORE, in consideration of the premises and the mutual
covenants hereinafter set forth, the parties hereto hereby agree as follows:

                            SECTION 1.  DEFINITIONS

                 1.1  Defined Terms.  As used in this Agreement, the following
terms shall have the following meanings:

                 "ABR":  for any day, a rate per annum (rounded upwards, if
         necessary, to the next 1/16 of 1%) equal to the greatest of (a) the
         Prime Rate in effect on such day, (b) the Base CD Rate in effect on
         such day plus 1% and (c) the Federal Funds Effective Rate in effect on
         such day plus 1/2 of 1%.  For purposes hereof:  "Prime Rate" shall
         mean the rate of interest per annum publicly announced from time to
         time by Chase as its prime rate in effect at its principal office in
         New York City (the Prime Rate not being intended to be the lowest rate
         of interest charged by Chase in connection with extensions of credit
         to debtors); "Base CD Rate" shall mean the sum of (a) the product of
         (i) the Three-Month Secondary CD Rate and (ii) a fraction, the
         numerator of which is one and the denominator of which is one minus
         the C/D Reserve Percentage and (b) the C/D Assessment Rate;
         "Three-Month Secondary CD Rate" shall mean, for any day, the secondary
         market rate for three-month certificates of deposit reported as being
         in effect on such day (or, if such day shall not be a Business Day,
         the next preceding Business Day) by the Board of Governors of the
         Federal Reserve System (the "Board") through the public information
         telephone line of the Federal Reserve Bank of New
<PAGE>   7
                                                                               2

         York (which rate will, under the current practices of the Board, be
         published in Federal Reserve Statistical Release H.15(519) during the
         week following such day), or, if such rate shall not be so reported on
         such day or such next preceding Business Day, the average of the
         secondary market quotations for three-month certificates of deposit of
         major money center banks in New York City received at approximately
         10:00 A.M., New York City time, on such day (or, if such day shall not
         be a Business Day, on the next preceding Business Day) by the
         Administrative Agent from three New York City negotiable certificate
         of deposit dealers of recognized standing selected by it; and "Federal

             SECTION 2.  AMOUNT AND TERMS OF REVOLVING COMMITMENTS

                 2.1  Revolving Credit Commitments.  (a)  Subject to the terms
and conditions hereof, each Lender severally agrees to make revolving credit
loans ("Revolving Credit Loans" or "Loans") to the Borrower from time to time
during the Commitment Period in an aggregate principal amount at any one time
outstanding not to exceed the amount of such Lender's Revolving Credit
Commitment, provided that no Lender shall make any Revolving Credit Loans if,
after giving effect thereto, the sum of such Lender's Revolving Credit Loans
and Commitment Percentage of Letter of Credit Outstandings (in each case, after
giving effect to the Loans requested to be made and the Letters of Credit
requested to be issued on such date) exceeds the lesser of (i) such Lender's
Revolving Credit Commitment and (ii) such Lender's Commitment Percentage of the
Borrowing Base then in effect.  During the Commitment Period, the Borrower may
use the Revolving Credit Commitments by borrowing, prepaying the Revolving
Credit Loans in whole or in part, and reborrowing, all in accordance with the
terms and conditions hereof.

                 (b)  The Revolving Credit Loans may from time to time be (i)
Eurodollar Loans, (ii) ABR Loans or (iii) a combination thereof, as determined
by the Borrower and notified to the Administrative Agent in accordance with
subsections 2.2 and 4.3, provided that no Revolving Credit Loan shall be made
as a Eurodollar Loan after the day that is one month prior to the Termination
Date.

                 2.2  Procedure for Revolving Credit Borrowing.  The Borrower
may borrow under the Revolving Credit Commitments during the Commitment Period
on any Business Day, provided that the Borrower shall give the Administrative
Agent irrevocable notice (which notice must be received by the Administrative
Agent prior to 10:00 a.m., New York City time, (a) three Business Days prior to
the requested Borrowing Date, if all or any part of the requested Revolving
Credit Loans initially are to be Eurodollar Loans or (b) one Business Day prior
to the requested Borrowing Date, otherwise), specifying (i) the amount to be
borrowed, (ii) the requested Borrowing Date, (iii) whether the borrowing is to
be of Eurodollar Loans, ABR Loans or a combination thereof and (iv) if the
borrowing is to be entirely or partly of Eurodollar Loans, the respective
amounts of each such Type of Loan and the respective lengths of the initial
Interest Periods therefor.  Each borrowing under the Revolving Credit
Commitments shall be in an amount equal to (x) in the case of ABR Loans,
$5,000,000 or a whole multiple of $1,000,000 in excess thereof (or, if the then
Available Commitments are less than $5,000,000, such lesser amount) and (y) in
the case of Eurodollar Loans, $5,000,000 or a whole multiple of $1,000,000 in
excess thereof.  Upon receipt of any such notice from the Borrower, the
Administrative Agent shall promptly notify each Lender thereof.  Each Lender
will make the amount of its pro rata share of each borrowing available to the
Administrative Agent for the account of the Borrower at the office of the
Administrative Agent specified in subsection 11.2 prior to 11:00 A.M., New York
City time, on the Borrowing Date requested by the Borrower in funds immediately
available to the Administrative Agent.  Such borrowing will then be made
available to the Borrower by the Administrative Agent crediting the account of
the Borrower on the books of such office with

                                                                              20

the aggregate of the amounts made available to the Administrative Agent by the
Lenders and in like funds as received by the Administrative Agent.

                 2.3  Repayment of Loans; Evidence of Debt.  (a)  The Borrower
hereby unconditionally promises to pay to the Administrative Agent for the
account of each Lender the then unpaid principal amount of each Loan of such
Lender on the Termination Date (or such earlier date on which the Loans become
due and payable pursuant to Section 9).  The Borrower hereby further agrees to
pay interest on the unpaid principal amount of the Loans from time to time
outstanding from the date hereof to but not including the date the Loans are
paid in full at the rates per annum, and on the dates, set forth in subsection
4.1.

                 (b)  Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of the Borrower to such
Lender resulting from each Loan of such Lender from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time under this Agreement.

                 (c)  The Administrative Agent shall maintain the Register
pursuant to subsection 11.6(d), and a subaccount therein for each Lender, in
which shall be recorded (i) the amount of each Loan made hereunder, the Type
thereof and each Interest Period applicable thereto, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) both the amount of any sum received
by the Administrative Agent hereunder from the Borrower and each Lender's share
thereof.

                 (d)  The entries made in the Register and the accounts of each
Lender maintained pursuant to subsection 2.3(b) shall, to the extent permitted
by applicable law, be prima facie evidence of the existence and amounts of the
obligations of the Borrower therein recorded; provided, however, that the
failure of the Administrative Agent or any Lender to maintain the Register or
any such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loans made
to such Borrower by such Lender in accordance with the terms of this Agreement.

                 (e)  The Borrower agrees that, upon the request to the
Administrative Agent by any Lender, the Borrower will execute and deliver to
such Lender a promissory note of the Borrower evidencing the Revolving Credit
Loans of such Lender, substantially in the form of Exhibit A with appropriate
insertions as to date and principal amount (a "Revolving Credit Note" or
"Note").


                         SECTION 3.  LETTERS OF CREDIT

                 3.1  The L/C Commitment.  (a)  Subject to the terms and
conditions hereof, the Issuing Lender, in reliance on the agreements of the
other Lenders set forth in subsection 3.4(a), agrees to issue letters of credit
("Letters of Credit") for the account of the Borrower on any Business Day
during the Commitment Period in such form as may be approved from time to time
by the Issuing Lender; provided that the Issuing Lender shall not issue any
Letter of Credit if, after giving effect to such issuance and after giving
effect to any Loans requested to be made or Letters of Credit requested to be
issued on such date, (i) the Letter of Credit Outstandings would exceed
$10,000,000 or (ii) the sum of the Revolving Credit Loans and Letter of Credit
Outstandings would exceed the lesser of (x) the Revolving Credit Commitments
and (y) the Borrowing Base then in effect.  Each Letter of Credit shall (i) be
issued to support obligations of the Borrower or any of its Subsidiaries,
contingent or otherwise, which finance the working capital and business needs
of the Borrower and its
<PAGE>   26
                                                                              21

Subsidiaries, and (ii) shall expire no later than the earlier of (x) one year
(or such later date agreed to by the Issuing Lender) after the date of issuance
and (y) five Business Days prior to the Termination Date, provided that any
Letter of Credit with a one-year tenor may provide for the extension thereof
for additional one-year periods (which shall in no event extend beyond the date
referred to in clause (y) above). Each Letter of Credit shall be denominated in
Dollars.

                 (b)  Each Letter of Credit shall be subject to the Uniform
Customs and, to the extent not inconsistent therewith, the laws of the State of
New York.

                 (c)  The Issuing Lender shall not at any time be obligated to
issue any Letter of Credit hereunder if such issuance would conflict with, or
cause the Issuing Lender or any Participating Lender to exceed any limits
imposed by, any applicable Requirement of Law.

                 3.2  Procedure for Issuance of Letters of Credit.  The
Borrower may from time to time request that the Issuing Lender issue a Letter
of Credit by delivering to the Issuing Lender and the Administrative Agent at
their respective addresses for notices specified herein a letter of credit
application in the Issuing Lender's then customary form (an "L/C Application")
completed to the satisfaction of the Issuing Lender, and such other
certificates, documents and other papers and information as may be customary
and as the Issuing Lender may reasonably request.  Upon receipt of any L/C
Application, the Issuing Lender will process such L/C Application and the
certificates, documents and other papers and information delivered to it in
connection therewith in accordance with its customary procedures and, upon
receipt by the Issuing Lender of confirmation from the Administrative Agent
that issuance of such Letter of Credit will not contravene subsection 3.1, the
Issuing Lender shall promptly issue the Letter of Credit requested thereby (but
in no event shall the Issuing Lender be required to issue any Letter of Credit
earlier than three Business Days after its receipt of the L/C Application
therefor and all such other certificates, documents and other papers and
information relating thereto) by issuing the original of such Letter of Credit
to the beneficiary thereof or as otherwise may be agreed by the Issuing Lender
and the Borrower.  The Issuing Lender shall furnish a copy of such Letter of
Credit to the Borrower and the Administrative Agent promptly following the
issuance thereof, and, thereafter, the Administrative Agent shall promptly
furnish a copy thereof to the Lenders.

                 3.3  Fees, Commissions and Other Charges.  (a)  The Borrower
shall pay to the Administrative Agent, for the account of (i) the Issuing
Lender and the Participating Lenders, a letter of credit commission with
respect to each Letter of Credit, computed for the period from the date such
Letter of Credit is issued to the date upon which the next payment is due under
this subsection (and, thereafter, from the date of payment under this
subsection to the date upon which the next payment is due under this
subsection) at the rate per annum equal to the Applicable Margin in effect from
time to time for Eurodollar Loans of the daily aggregate amount available to be
drawn under such Letter of Credit during such period, and (ii) the Issuing
Lender, a letter of credit commission with respect to each Letter of Credit in
an amount equal to .125% per annum of the daily aggregate amount available to
be drawn under such Letter of Credit.  The letter of credit commissions payable
pursuant to clause (i) and (ii) above shall be payable quarterly in arrears on
the last day of each March, June, September and December, commencing December
31, 1997, and on the Termination Date.

                 (b)  In addition to the foregoing fees and commissions, the
Borrower shall pay or reimburse the Issuing Lender for such normal and
customary costs and expenses as are incurred or charged by the Issuing Lender
in issuing, effecting payment under, amending, negotiating or otherwise
administering any Letter of Credit.
<PAGE>   27
                                                                              22


                 (c)  The Administrative Agent shall, promptly following its
receipt thereof, distribute to the Issuing Lender and the Participating Lenders
all fees and commissions received by the Administrative Agent for their
respective accounts pursuant to this subsection.

                 3.4  L/C Participations.  (a)  Effective on the date of
issuance of each Letter of Credit, the Issuing Lender irrevocably agrees to
grant and hereby grants to each Participating Lender, and each Participating
Lender irrevocably agrees to accept and purchase and hereby accepts and
purchases from the Issuing Lender, on the terms and conditions hereinafter
stated, for such Participating Lender's own account and risk an undivided
interest equal to such Participating Lender's Commitment Percentage in the
Issuing Lender's obligations and rights under each Letter of Credit issued by
the Issuing Lender and the amount of each draft paid by the Issuing Lender
thereunder.  Each Participating Lender unconditionally and irrevocably agrees
with the Issuing Lender that, if a draft is paid under any Letter of Credit for
which such Issuing Lender is not reimbursed in full by the Borrower in
accordance with the terms of this Agreement, such Participating Lender shall
pay to the Administrative Agent, for the account of the Issuing Lender, upon
demand at the Administrative Agent's address specified in subsection 11.2, an
amount equal to such Participating Lender's Commitment Percentage of the amount
of such draft, or any part thereof, which is not so reimbursed.  On the date
that any Assignee becomes a Lender party to this Agreement in accordance with
subsection 11.6, participating interests in any outstanding Letters of Credit
held by the transferor Lender from which such Assignee acquired its interest
hereunder shall be proportionately reallotted between such Assignee and such
transferor Lender.  Each Participating Lender hereby agrees that its obligation
to participate in each Letter of Credit, and to pay or to reimburse the Issuing
Lender for its participating share of the drafts drawn or amounts otherwise
paid thereunder, is absolute, irrevocable and unconditional and shall not be
affected by any circumstances whatsoever (including, without limitation, the
occurrence or continuance of any Default or Event of Default), and that each
such payment shall be made without offset, abatement, withholding or other
reduction whatsoever.

                 (b)  If any amount required to be paid by any Participating
Lender to the Issuing Lender pursuant to subsection 3.4(a) in respect of any
unreimbursed portion of any draft paid by the Issuing Lender under any Letter
of Credit is paid to the Issuing Lender within three Business Days after the
date such payment is due, such Participating Lender shall pay to the
Administrative Agent, for the account of the Issuing Lender, on demand, an
amount equal to the product of (i) such amount, times (ii) the daily average
Federal Funds Effective Rate during the period from and including the date such
draft is paid to the date on which such payment is immediately available to the
Issuing Lender, times (iii) a fraction the numerator of which is the number of
days that elapse during such period and the denominator of which is 360.  If
any such amount required to be paid by any Participating Lender pursuant to
subsection 3.4(a) is not in fact made available to the Administrative Agent,
for the account of the Issuing Lender, by such Participating Lender within
three Business Days after the date such payment is due, the Issuing Lender
shall be entitled to recover from such Participating Lender, on demand, such
amount with interest thereon calculated from such due date at the rate per
annum applicable to ABR Loans hereunder.  A certificate of the Issuing Lender
submitted to any Participating Lender with respect to any amounts owing under
this subsection shall be conclusive in the absence of manifest error.

                 (c)  Whenever, at any time after the Issuing Lender has paid a
draft under any Letter of Credit and has received from any Participating Lender
its pro rata share of such payment in accordance with subsection 3.4(a), the
Issuing Lender receives any reimbursement on account of such unreimbursed
portion, or any payment of interest on account thereof, the Issuing Lender will
pay to the Administrative Agent, for the account of such Participating Lender,
its pro rata share thereof; provided, however, that in the event that any such
payment received by the Issuing Lender shall be
<PAGE>   28
                                                                              23

required to be returned by the Issuing Lender, such Participating Lender shall
return to the Administrative Agent for the account of the Issuing Lender, the
portion thereof previously distributed to it.

                 3.5  Reimbursement Obligation of the Borrower.  If any draft
shall be presented for payment under any Letter of Credit, the Issuing Lender
shall notify the Borrower and the Administrative Agent of the date and the
amount thereof.  The Borrower agrees to reimburse the Issuing Lender (whether
with its own funds or with proceeds of the Revolving Credit Loans) on each date
on which the Issuing Lender pays a draft so presented under any Letter of
Credit for the amount of (i) such draft so paid and (ii) any taxes, fees,
charges or other costs or expenses incurred by the Issuing Lender in connection
with such payment.  Each such payment shall be made to the Issuing Lender at
its address for notices specified herein in lawful money of the United States
of America and in immediately available funds.  Interest shall be payable on
any and all amounts remaining unpaid by the Borrower under this subsection from
the date of payment of the applicable draft until payment in full thereof, (x)
for the period commencing on the date of payment of the applicable draft to the
date which is 3 days thereafter, at the rate which would be payable on ABR
Loans at such time and (y) thereafter, at the rate which would be payable on
ABR Loans at such time plus 2%.

                 3.6  Obligations Absolute.  The Borrower's obligations under
this Section 3 shall be absolute and unconditional under any and all
circumstances and irrespective of any set-off, counterclaim or defense to
payment which the Borrower or any other Person may have or have had against the
Issuing Lender or any other Lender or any beneficiary of a Letter of Credit.
The Borrower also agrees with the Issuing Lender that the Issuing Lender shall
not be responsible for, and the Borrower's obligations under subsection 3.5
shall not be affected by, among other things, the validity or genuineness of
documents or of any endorsements thereon, even though such documents shall in
fact prove to be invalid, fraudulent or forged, or any dispute between or among
the Borrower and any beneficiary of any Letter of Credit or any other party to
which such Letter of Credit may be transferred or any claims whatsoever of the
Borrower against any beneficiary of such Letter of Credit or any such
transferee.  The Issuing Lender shall not be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit, except
for errors or omissions caused by the Issuing Lender's gross negligence or
willful misconduct.  The Borrower agrees that any action taken or omitted by
the Issuing Lender under or in connection with any Letter of Credit or the
related drafts or documents, if done in the absence of gross negligence or
willful misconduct and in accordance with the standards of care specified in
the Uniform Commercial Code of the State of New York, including, without
limitation, Article V thereof, shall be binding on the Borrower and shall not
result in any liability of such Issuing Lender to the Borrower.

                 3.7  Letter of Credit Payments.  Without limitation of
subsection 3.6, the responsibility of the Issuing Lender to the Borrower in
connection with any draft presented for payment under any Letter of Credit
shall, in addition to any payment obligation expressly provided for in such
Letter of Credit, be limited to determining that the documents (including each
draft) delivered under such Letter of Credit in connection with such
presentment are in conformity with such Letter of Credit.

                 3.8  L/C Applications.  To the extent that any provision of
any L/C Application, including any reimbursement provisions contained therein,
related to any Letter of Credit is inconsistent with the provisions of this
Section 3, the provisions of this Section 3 shall prevail.

                         SECTION 4.  GENERAL PROVISIONS

                 4.1  Interest Rates and Payment Dates.  (a)  Each Eurodollar
Loan shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such
Interest Period plus the Applicable Margin in effect on such day.

                 (b)  Each ABR Loan shall bear interest for each day at a rate
per annum equal to the ABR in effect on such day plus the Applicable Margin in
effect on such date.

                 (c)  If all or a portion of (i) any principal of any Loan,
(ii) any interest payable thereon, (iii) any commitment fee or (iv) any other
amount payable hereunder shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), the principal of the Loans and any
such overdue interest, commitment fee or other amount shall bear interest at a
rate per annum which is (x) in the case of principal, the rate that would
otherwise be applicable thereto pursuant to the foregoing provisions of this
subsection plus 2% or (y) in the case of any such overdue interest, commitment
fee or other amount, the ABR plus the Applicable Margin in effect on such date
plus 2%, in each case from the date of such non-payment until such overdue
principal, interest, commitment fee or other amount is paid in full (as well
after as before judgment).

                 (d)  Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing pursuant to subsection 4.1(c)
shall be payable from time to time on demand.

                 4.2  Computation of Interest and Fees.  (a)  Whenever, in the
case of ABR Loans, it is calculated on the basis of the Prime Rate, interest
shall be calculated on the basis of a 365- (or 366-, as the case may be) day
year for the actual days elapsed; and, otherwise, interest and fees shall be
calculated on the basis of a 360-day year for the actual days elapsed.  The
Administrative Agent shall as soon as practicable notify the Borrower and the
Lenders of each determination of a Eurodollar Rate.  Any change in the interest
rate on a Loan resulting from a change in the ABR, the Eurocurrency Reserve
Requirements, the C/D Assessment Rate or the C/D Reserve Percentage shall
become effective as of the opening of business on the day on which such change
becomes effective.  The Administrative Agent shall as soon as practicable
notify the Borrower and the Lenders of the effective date and the amount of
each such change in interest rate.

                 (b)  Each determination of an interest rate by the
Administrative Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of
manifest error.  The Administrative Agent shall, at the request of the
Borrower, deliver to the Borrower a statement showing the quotations and
calculations used by the Administrative Agent in determining any interest rate
pursuant to subsection 4.1(a).

                 4.3  Conversion and Continuation Options.  (a)  The Borrower
may elect from time to time to convert Eurodollar Loans to ABR Loans by giving
the Administrative Agent at least one Business Day's prior irrevocable notice
of such election, provided that any such conversion of Eurodollar Loans may
only be made on the last day of an Interest Period with respect thereto.  The
Borrower may elect from time to time to convert ABR Loans to Eurodollar Loans
by giving the Administrative Agent at least three Business Days' prior
irrevocable notice of such election.  Any such notice of conversion to
Eurodollar Loans shall specify the length of the initial Interest Period or
Interest Periods therefor.  Upon receipt of any such notice the Administrative
Agent shall promptly notify each Lender thereof.  All or any part of
outstanding Eurodollar Loans and ABR Loans may be converted as provided herein,
provided that (i) no Loan may be converted into a Eurodollar Loan when any
Event of Default has occurred and is continuing and the Administrative Agent
has or the
<PAGE>   30
                                                                              25

Required Lenders have determined that such a conversion is not appropriate and
(ii) no Loan may be converted into a Eurodollar Loan after the date that is one
month prior to the Termination Date.

                 (b)  Any Eurodollar Loans may be continued as such upon the
expiration of the then current Interest Period with respect thereto by the
Borrower giving notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in subsection
1.1, of the length of the next Interest Period to be applicable to such Loans,
provided that no Eurodollar Loan may be continued as such (i) when any Event of
Default has occurred and is continuing and the Administrative Agent has or the
Required Lenders have determined that such a continuation is not appropriate or
(ii) after the date that is one month prior to the Termination Date and
provided, further, that if the Borrower shall fail to give such notice or if
such continuation is not permitted such Loans shall be automatically converted
to ABR Loans on the last day of such then expiring Interest Period.

                 4.4  Minimum Amounts Maximum Number of Tranches.  All
borrowings, conversions and continuations of Loans hereunder and all selections
of Interest Periods hereunder shall be in such amounts and be made pursuant to
such elections so that, after giving effect thereto, the aggregate principal
amount of the Loans comprising each Eurodollar Tranche shall be equal to
$5,000,000 or a whole multiple of $1,000,000 in excess thereof.  In no event
shall there be more than five Eurodollar Tranches outstanding at any time.

                 4.5  Optional Prepayments and Commitment Reductions.  (a)  The
Borrower may, on the last day of any Interest Period with respect thereto, in
the case of Eurodollar Loans, or at any time and from time to time, in the case
of ABR Loans, prepay the Loans, in whole or in part, without premium or
penalty, upon at least one Business Day's irrevocable notice to the
Administrative Agent in the case of ABR Loans, and upon at least three Business
Days' irrevocable notice to the Administrative Agent in the case of Eurodollar
Loans, in each case specifying the date and amount of prepayment and whether
the prepayment is of Eurodollar Loans, ABR Loans or a combination thereof, and,
in each case if of a combination thereof, the amount allocable to each.  Upon
receipt of any such notice the Administrative Agent shall promptly notify each
Lender thereof.  If any such notice is given, the amount specified in such
notice shall be due and payable on the date specified therein, together with
any amounts payable pursuant to subsection 4.14.  Partial prepayments shall be
in an aggregate principal amount of $5,000,000 or a whole multiple thereof.

                 (b)  Subject to subsection 4.5(c), the Borrower shall have the
right, upon not less than three Business Days' notice to the Administrative
Agent, to terminate the Revolving Credit Commitments or, from time to time, to
reduce the amount of the Revolving Credit Commitments.  Any such reduction
shall be in an amount equal to $5,000,000 or a whole multiple of $1,000,000 in
excess thereof and shall reduce permanently the Revolving Credit Commitments
then in effect.  Termination of the Revolving Credit Commitments shall also
terminate the obligation of the Issuing Lender to issue Letters of Credit.

                 (c)  In the event of any termination of the Revolving Credit
Commitments, the Borrower shall on the date of such termination repay or prepay
all of its outstanding Revolving Credit Loans (together with accrued and unpaid
interest on the Revolving Credit Loans and any amounts payable pursuant to
subsection 4.14 and any other amounts payable hereunder), reduce the Letter of
Credit Outstandings to zero and cause all Letters of Credit to be canceled and
returned to the Issuing Lender (or shall cash collateralize the Letter of
Credit Outstandings (or provide supporting letters of credit from an
institution reasonably acceptable to the Administrative Agent) on terms and
pursuant to documentation reasonably satisfactory to the Issuing Lender and the
Administrative Agent).  In the event of any partial reduction of the Revolving
Credit Commitments, then (i) at or prior to the
<PAGE>   31
                                                                              26

effective date of such reduction, the Administrative Agent shall notify the
Borrower and the Lenders of the Aggregate Revolving Credit Exposure of all the
Lenders and (ii) if the Aggregate Revolving Credit Exposure of all the Lenders
would exceed the aggregate Commitments after giving effect to such reduction,
then, prior to giving effect to such reduction, the Borrower shall, on the date
of such reduction, first, repay or prepay Revolving Credit Loans and, second,
reduce the Letter of Credit Outstandings (or cash collateralize the Letter of
Credit Outstandings (or provide supporting letters of credit from an
institution reasonably acceptable to the Administrative Agent) on terms and
pursuant to documentation reasonably satisfactory to the Issuing Lender and the
Administrative Agent), in an aggregate amount sufficient to eliminate such
excess.

                 (d)  The Loans shall be repaid, and the Letter of Credit
Outstandings shall be reduced or cash collateralized, to the extent required by
subsection 4.10.  All such repayments and cash collateralization shall be made
in accordance with this subsection 4.5.

                 (e) In the event the amount of any prepayment of the Loans
required to be made above shall exceed the aggregate principal amount of the
outstanding ABR Loans (the amount of any such excess being called the "Excess
Amount"), the Borrower shall have the right, in lieu of making such prepayment
in full, to prepay all the outstanding applicable ABR Loans and to deposit an
amount equal to the Excess Amount with, and (ii) in the event that Letter of
Credit Outstandings are required to be cash collateralized, the Borrower shall
deposit an amount equal to the aggregate amount of Letter of Credit
Outstandings to be cash collateralized with, the Administrative Agent in a cash
collateral account maintained (pursuant to documentation reasonably
satisfactory to the Administrative Agent) by and in the sole dominion and
control of the Administrative Agent.  Any amounts so deposited shall be held by
the Administrative Agent as collateral for the obligations of the Borrower
under this Agreement and applied to the prepayment of the applicable Eurodollar
Loans at the end of the current Interest Periods applicable thereto or Letter
of Credit Outstandings, as the case may be, or, during an Event of Default, to
payment of any obligations under this Agreement (including obligations in
respect of the Letters of Credit).  On any Business Day on which (i) collected
amounts remain on deposit in or to the credit of such cash collateral account
after giving effect to the payments made on such day pursuant to this
subsection 4.5(e) and (ii) the Borrower shall have delivered to the
Administrative Agent a written request or a telephonic request (which shall be
promptly confirmed in writing) that such remaining collected amounts be
invested in the Cash Equivalent specified in such request, the Administrative
Agent shall use its reasonable efforts to invest such remaining collected
amounts in such Cash Equivalent, provided, however, that the Administrative
Agent shall have continuous dominion and full control over any such investments
(and over any interest that accrues thereon) to the same extent that it has
dominion and control over such cash collateral account and no Cash Equivalent
shall mature after the end of the Interest Period for which it is to be
applied.  The Borrower shall not have the right to withdraw any amount from
such cash collateral account until the applicable Eurodollar Loans and accrued
interest thereon and Letter of Credit Outstandings are paid in full or if a
Default or Event of Default then exists or would result.  Any prepayment or
collateralization pursuant to this subsection 4.5(e) shall be applied in the
order set forth in clause (ii) of the second sentence of subsection 4.5(c).

                 4.6  Commitment Fee; Administrative Agent's Fee; Other Fees.
(a)  The Borrower agrees to pay to the Administrative Agent for the account of
each Lender a commitment fee for the period from and including, for each
Lender, the Closing Date to but not including the Termination Date, computed at
the Commitment Fee Rate on the average daily amount of the lesser of (i) the
Available Commitment of such Lender and (ii) the Borrowing Base Availability
with respect to such Lender, during the period for which payment is made,
payable quarterly in arrears on the last day of each March, June, September and
December (commencing on December 31, 1997) and on the
<PAGE>   32
                                                                              27

Termination Date or such earlier date as the Revolving Credit Commitments shall
terminate as provided herein, commencing on the first of such dates to occur
after the date hereof.  Commitment fees shall be nonrefundable when paid.

                 (b)  The Borrower shall pay to the Administrative Agent the
fees set forth in the fee letter agreement, dated October 29, 1997, among the
Borrower, Chase and Chase Securities Inc., on the dates specified therein.

                 4.7  Inability to Determine Interest Rate.  If prior to the
         first day of any Interest Period:

                 (a)  the Administrative Agent shall have determined (which
         determination shall be conclusive and binding upon the Borrower) that,
         by reason of circumstances affecting the relevant market, adequate and
         reasonable means do not exist for ascertaining the Eurodollar Rate for
         such Interest Period, or

                 (b)  the Administrative Agent shall have received notice from
         the Required Lenders that the Eurodollar Rate determined or to be
         determined for such Interest Period will not adequately and fairly
         reflect the cost to such Lenders (as conclusively certified by such
         Lenders) of making or maintaining their affected Loans during such
         Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to
the Borrower and the Lenders as soon as practicable thereafter.  If such notice
is given (x) any Eurodollar Loans requested to be made on the first day of such
Interest Period shall be made as ABR Loans, (y) any Loans that were to have
been converted on the first day of such Interest Period to Eurodollar Loans
shall be continued as ABR Loans and (z) any outstanding Eurodollar Loans shall
be converted, on the first day of such Interest Period, to ABR Loans.  Until
such notice has been withdrawn by the Administrative Agent, no further
Eurodollar Loans shall be made or continued as such, nor shall the Borrower
have the right to convert Loans to Eurodollar Loans.

                 4.8  Pro Rata Treatment and Payments.  (a)  Each borrowing by
the Borrower from the Lenders hereunder, each payment by the Borrower on
account of any commitment fee hereunder and any reduction of the Revolving
Credit Commitments of the Lenders shall be made pro rata according to the
respective Commitment Percentages of the Lenders.  Each payment (including each
prepayment) by the Borrower on account of principal of and interest on the
Loans shall be made pro rata according to the respective outstanding principal
amounts of the Loans then held by the Lenders.  All payments (including
prepayments) to be made by the Borrower hereunder, whether on account of
principal, interest, fees or otherwise, shall be made without set off or
counterclaim and shall be made prior to 12:00 Noon, New York City time, on the
due date thereof to the Administrative Agent, for the account of the Lenders,
at the Administrative Agent's office specified in subsection 11.2, in Dollars
and in immediately available funds.  The Administrative Agent shall distribute
such payments to the Lenders promptly upon receipt in like funds as received.
If any payment hereunder becomes due and payable on a day other than a Business
Day, such payment shall be extended to the next succeeding Business Day, and,
with respect to payments of principal, interest thereon shall be payable at the
then applicable rate during such extension.

                 (b)  Unless the Administrative Agent shall have been notified
in writing by any Lender prior to a borrowing that such Lender will not make
the amount that would constitute its Commitment Percentage of such borrowing
available to the Administrative Agent, the Administrative Agent may assume that
such Lender is making such amount available to the Administrative Agent, and
the
<PAGE>   33
                                                                              28

Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount.  If such amount is not made available to
the Administrative Agent by the required time on the Borrowing Date therefor,
such Lender shall pay to the Administrative Agent, on demand, such amount with
interest thereon at a rate equal to the daily average Federal Funds Effective
Rate for the period until such Lender makes such amount immediately available
to the Administrative Agent.  A certificate of the Administrative Agent
submitted to any Lender with respect to any amounts owing under this subsection
shall be conclusive in the absence of manifest error.  If such Lender's
Commitment Percentage of such borrowing is not made available to the
Administrative Agent by such Lender within three Business Days after such
Borrowing Date, the Administrative Agent shall also be entitled to recover such
amount with interest thereon at the rate per annum applicable to ABR Loans
hereunder, on demand, from the Borrower.

                 4.9  Computation of Borrowing Base.  (a) (i)  The Borrowing
Base in effect from time to time shall represent the maximum principal amount
(subject to the aggregate amount of the Revolving Credit Commitments) of Loans
and Letter of Credit Outstandings that the Lenders will allow to remain
outstanding during the Commitment Period.  During the Initial Period, the
amount of the Borrowing Base shall be $125,000,000, unless revised upon the
occurrence of a Redetermination Event, as set forth in subsection 4.9(e).  The
Borrowing Base will be based upon the value of certain Proved Reserves
attributable to the Oil and Gas Properties of the Borrower and its Subsidiaries
and other assets of the Borrower and its Subsidiaries acceptable to the
Administrative Agent in its sole discretion, and will be determined by the
Administrative Agent in accordance with paragraph (d) of this subsection 4.9,
subject to approval by the Supermajority Lenders (or, with respect to the
Initial Scheduled Borrowing Base Redetermination, all of the Lenders).  Until
the Commitments are no longer in effect, all Letters of Credit have terminated
and all of the Loans and all other obligations under this Agreement are paid in
full, this Agreement shall be subject to the then effective Borrowing Base.

                 (b)  Reserve Reports.  Prior to March 1 and September 1 of
each year, the Borrower shall, at its own expense, furnish to the
Administrative Agent and to each Lender Reserve Reports, which Reserve Reports
shall be dated as of the immediately preceding December 31 (in the case of
Reserve Reports due on March 1) and June 30 (in the case of Reserve Reports due
on September 1), and shall set forth, among other things, (i) the Oil and Gas
Properties, then owned by the Borrower and its Subsidiaries, (ii) the Proved
Reserves attributable to such Oil and Gas Properties and (iii) a projection of
the rate of production and net income of the Proved Reserves as of the date of
such Reserve Report, all in accordance with the guidelines published by the
Securities and Exchange Commission and such assumptions as the Administrative
Agent shall provide.   Concurrently with the delivery of the Reserve Reports,
the Borrower shall furnish to the Administrative Agent and to each Lender a
certificate of a Responsible Officer showing any additions to or deletions from
the Oil and Gas Properties listed in the Reserve Report, which additions or
deletions were made by the Borrower and its Subsidiaries since the date of the
previous Reserve Report.

                 (c)  Redeterminations of the Borrowing Base after the Initial
Period.  The Borrowing Base shall be redetermined (i) after receipt by the
Administrative Agent of each scheduled Reserve Report, commencing with the
Reserve Report as of December 31, 1997, (ii) upon the delivery, after the
Initial Period, of a Lender Redetermination Notice to the Borrower and (iii)
upon the delivery, after the Initial Period, of a Borrower Redetermination
Notice to the Administrative Agent, all as provided in this subsection 4.9.
Within 15 days after the delivery of a Borrower Redetermination Notice or a
Lender Redetermination Notice, the Borrower shall furnish to the Administrative
Agent and to each Lender a Reserve Report as of the most recent practicable
date.  If the Borrower fails to deliver a Reserve Report within the time period
provided for in the preceding sentence, then the
<PAGE>   34
                                                                              29

Administrative Agent shall have the right to rely on the last Reserve Report
previously delivered by the Borrower with any such adjustments and taking into
account any additional information as the Administrative Agent may deem
appropriate, in its sole discretion.  On or before the date which is 30 days
after receipt (i) of a scheduled semi- annual Reserve Report or (ii) of a
Reserve Report in connection with a Lender Redetermination Notice or a Borrower
Redetermination Notice, the Administrative Agent shall redetermine the
Borrowing Base in its sole discretion, and the Administrative Agent shall
notify the Borrower and the Lenders of its redetermination of the Borrowing
Base.  Within 10 days after receipt from the Administrative Agent of the amount
of the its redetermination of the Borrowing Base, each Lender shall notify the
Administrative Agent stating whether or not such Lender agrees with that
redetermination.  Failure of any Lender to give such notice within such period
of time shall be deemed to constitute an acceptance of such redetermination.
If the Supermajority Lenders (or, with respect to the Initial Scheduled
Borrowing Base Redetermination, all of the Lenders) agree with that
redetermination, then the Administrative Agent promptly shall notify the
Borrower of the Borrowing Base as so redetermined, whereupon that redetermined
value shall automatically become effective (and shall remain effective until
the Borrowing Base is again redetermined as provided in this subsection
4.9(c)).  If the Supermajority Lenders (or, with respect to the Initial
Scheduled Borrowing Base Redetermination, all of the Lenders) have not approved
or are not deemed to have approved the Borrowing Base within the 10 day period
following their receipt of the proposed amount from the Administrative Agent,
the Borrowing Base shall be set at the amount of the then current Borrowing
Base and the Borrowing Base shall remain at such level until the Supermajority
Lenders (or, with respect to the Initial Scheduled Borrowing Base
Redetermination, all of the Lenders), utilizing the procedure outlined herein,
agree on a new Borrowing Base.  Each redetermination provided for by this
subsection 4.9(c) shall be made in accordance with the provisions of subsection
4.9(d).  It is the intention of the Borrower and the Lenders that the Borrowing
Base be redetermined within 45 days after the furnishing of each Reserve
Report, subject to the provisions of this paragraph (c); provided that it is
the intention of the Borrower and the Lenders that the Initial Scheduled
Borrowing Base Redetermination shall occur by, and shall become effective at,
the end of the Initial Period.

                 (d)  (i)  All determinations and redeterminations by the
Administrative Agent provided for in this subsection 4.9 (and any
determinations and decisions by either or both of the Administrative Agent and
the Supermajority Lenders (or, with respect to the Initial Scheduled Borrowing
Base Redetermination, all of the Lenders) in connection therewith, including
effecting any redetermination of the value of any component contained in a
Reserve Report) shall be made by the Administrative Agent and the Lenders in
their sole discretion and shall be made on a reasonable basis and in good faith
based upon the application by the Administrative Agent and the Lenders of their
respective normal oil and gas lending criteria as they exist at the time of
determination.

                 (ii)  All redeterminations of the Borrowing Base referred to
in this subsection 4.9 shall become effective immediately upon the delivery of
notice by the Administrative Agent to the Borrower of the redetermination;
provided that the Initial Scheduled Borrowing Base Redetermination shall not
become effective until the end of the Initial Period.

                 (iii)  (x) Upon the issuance of Subordinated Indebtedness
pursuant to subsection 8.2(f) during the Initial Period, the Borrowing Base
shall be automatically reduced in accordance with subsection 4.9(e) and (y)
upon the issuance of any such Subordinated Indebtedness following the Initial
Period, the Borrowing Base shall be redetermined in accordance with the
procedures set forth in subsection 4.9 which would have applied had a Borrower
Redetermination Notice or a Lender Redetermination Notice been delivered.

                                                                              30


                 (e)  Redetermination Events during the Initial Period.  Upon
the occurrence during the Initial Period of a Redetermination Event described
in clauses (a), (b), (c) or (d) of the definition thereof, the Borrowing Base
shall be automatically reduced by an amount equal to the Net Proceeds of that
Redetermination Event and the Borrower shall promptly provide the
Administrative Agent and the Lenders notice of such a Redetermination Event and
the Net Proceeds realized therefrom (describing the same in reasonable detail).
In addition, an Oil and Gas Acquisition described in clause (e) of the
definition of Redetermination Event shall result in a mandatory redetermination
of the Borrowing Base pursuant to the procedures set forth in this subsection
4.9 for a redetermination following the delivery of a Lender Redetermination
Notice or a Borrower Redetermination Notice; provided that any such
redetermination of the Borrowing Base must be approved by all of the Lenders.

                 (f)  Concurrently with the delivery to the Administrative
Agent of each Reserve Report, the Administrative Agent may request that the
Borrower furnish to the Administrative Agent reasonable evidence of the
Borrower's title to the Oil and Gas Properties which have been developed or
acquired by the Borrower subsequent to the Reserve Report immediately preceding
such Reserve Report.

                 4.10  Borrowing Base Compliance.  If, upon any redetermination
of the Borrowing Base, the Aggregate Revolving Credit Exposure of the Lenders
exceeds the Borrowing Base then in effect (any such excess, the "Borrowing Base
Deficiency"), the Borrower shall prepay the Revolving Credit Loans and then
cash collateralize the Letter of Credit Outstandings in an amount equal to 50%
of the Borrowing Base Deficiency within 90 days after the effective date of the
redetermination resulting in such Borrowing Base Deficiency, and within the
next 90 days prepay the Revolving Credit Loans and then cash collateralize the
Letter of Credit Outstandings in an amount equal to the balance of such
Borrowing Base Deficiency in each case together with interest accrued to the
date of such payment or prepayment and any amounts payable under subsection
4.14; provided that, if there exists a Borrowing Base Deficiency upon the
termination of the Initial Period after giving effect to the Initial Scheduled
Borrowing Base Redetermination, the Borrower shall, within 60 days of the
Initial Scheduled Borrowing Base Redetermination, prepay the Revolving Credit
Loans and then cash collateralize the Letter of Credit Outstandings (together
with interest accrued to the date of such payment or prepayment and any amounts
payable under subsection 4.14) in an amount equal to such Borrowing Base
Deficiency.  If at any other time there exists a Borrowing Base Deficiency, the
Borrower shall immediately prepay the Loans and then cash collateralize the
Letter of Credit Outstandings in an amount equal to 100% of such Borrowing Base
Deficiency together with (i) interest accrued to the date of such payment or
prepayment and (ii) any amounts payable under subsection 4.14.  Notwithstanding
the foregoing, the Borrower shall immediately apply 100% of the Net Proceeds of
any Redetermination Event described in clauses (a), (b) (c) or (d) of the
definition thereof to prepay outstanding Loans and then cash collateralize the
Letter of Credit Outstandings.  Prepayments and collateralization pursuant to
this subsection 4.10 shall be made as set forth in subsection 4.5(c).

                 4.11  Illegality.  Notwithstanding any other provision herein,
if the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof after the date hereof shall make it
unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by
this Agreement (a) the commitment of such Lender hereunder to make Eurodollar
Loans, continue Eurodollar Loans as such and convert ABR Loans to Eurodollar
Loans shall forthwith be canceled and (b) such Lender's Loans then outstanding
as Eurodollar Loans, if any, shall be converted automatically to ABR Loans on
the respective last days of the then current Interest Periods with respect to
such Loans or within such earlier period as required by law.  If any such
conversion of a Eurodollar Loan occurs on a day which is not the last day of
the then current Interest Period with respect thereto, the
<PAGE>   36

Borrower shall pay to such Lender such amounts, if any, as may be required
pursuant to subsection 4.14.

                 4.12  Requirements of Law.  (a)  If the adoption of or any
change in any Requirement of Law or in the interpretation or application
thereof after the date hereof or compliance by any Lender with any request or
directive (whether or not having the force of law) from any central bank or
other Governmental Authority made subsequent to the date hereof:

                      (i)   shall subject any Lender to any tax of any kind
         whatsoever with respect to this Agreement, any Note, any Letter of
         Credit, any L/C Application or any Eurodollar Loan made by it, or
         change the basis of taxation of payments to such Lender in respect
         thereof (except for Non-Excluded Taxes covered by subsection 4.13,
         changes in the rate or computation of tax on the overall net income of
         such Lender, franchise taxes imposed in lieu of net income taxes and
         doing business taxes);

                      (ii)  shall impose, modify or hold applicable any
         reserve, special deposit, compulsory loan or similar requirement
         against assets held by, deposits or other liabilities in or for the
         account of, advances, loans or other extensions of credit by, or any
         other acquisition of funds by, any office of such Lender which is not
         otherwise included in the determination of the Eurodollar Rate
         hereunder; or

                      (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting
into, continuing or maintaining Eurodollar Loans or issuing or participating in
Letters of Credit or to reduce any amount receivable hereunder in respect
thereof, then, in any such case, the Borrower shall promptly pay such Lender
such additional amount or amounts as will compensate such Lender for such
increased cost or reduced amount receivable.

                 (b)  If any Lender shall have determined that the adoption of
or any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under any Letter of Credit to a
level below that which such Lender or such corporation could have achieved but
for such adoption, change or compliance (taking into consideration such
Lender's or such corporation's policies with respect to capital adequacy) by an
amount deemed by such Lender to be material, then from time to time, the
Borrower shall promptly pay to such Lender such additional amount or amounts as
will compensate such Lender for such reduction.

                 (c)  If any Lender becomes entitled to claim any additional
amounts pursuant to this subsection, it shall promptly notify the Borrower
(with a copy to the Administrative Agent) of the event by reason of which it
has become so entitled.  A certificate as to any additional amounts payable
pursuant to this subsection submitted by such Lender to the Borrower (with a
copy to the Administrative Agent) shall be conclusive in the absence of
manifest error.  The agreements in this subsection shall survive the
termination of this Agreement and the payment of the Loans and all other
amounts payable hereunder.
<PAGE>   37
                                                                              32


                 4.13  Taxes.  (a)  All payments made by the Borrower under
this Agreement and any Notes shall be made free and clear of, and without
deduction or withholding for or on account of, any present or future income,
stamp or other taxes, levies, imposts, duties, charges, fees, deductions or
withholdings, now or hereafter imposed, levied, collected, withheld or assessed
by any Governmental Authority, excluding net income taxes, franchise taxes
(imposed in lieu of net income taxes) and doing business taxes imposed on the
Administrative Agent or any Lender as a result of a present or former
connection between the Administrative Agent or such Lender and the jurisdiction
of the Governmental Authority imposing such tax or any political subdivision or
taxing authority thereof or therein (other than any such connection arising
solely from the Administrative Agent or such Lender having executed, delivered
or performed its obligations or received a payment under, or enforced, this
Agreement or any Note).  If any such non-excluded taxes, levies, imposts,
duties, charges, fees deductions or withholdings ("Non-Excluded Taxes") are
required to be withheld from any amounts payable to the Administrative Agent or
any Lender hereunder or under any Note, the amounts so payable to the
Administrative Agent or such Lender shall be increased to the extent necessary
to yield to the Administrative Agent or such Lender (after payment of all
Non-Excluded Taxes) interest or any such other amounts payable hereunder at the
rates or in the amounts specified in this Agreement, provided, however, that
the Borrower shall not be required to increase any such amounts payable to any
Non-U.S. Lender if such Non-U.S. Lender fails to comply with the requirements
of paragraph (b) of this subsection.  Whenever any Non-Excluded Taxes are
payable by the Borrower, as promptly as possible thereafter the Borrower shall
send to the Administrative Agent for its own account or for the account of such
Lender, as the case may be, a certified copy of an original official receipt
received by the Borrower showing payment thereof.  If, when the Borrower is
required by this subsection 4.14(a) to pay any Non-Excluded Taxes, the Borrower
fails to pay any Non-Excluded Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts
or other required documentary evidence, the Borrower shall indemnify the
Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as
a result of any such failure.  The agreements in this subsection shall survive
the termination of this Agreement and the payment of the Loans and all other
amounts payable hereunder.

                 (b)  Each Lender (or Transferee) that is not a citizen or
resident of the United States of America, a corporation, partnership or other
entity created or organized in or under the laws of the United States of
America, or any estate or trust that is subject to federal income taxation
regardless of the source of its income (a "Non-U.S.  Lender") shall deliver to
the Borrower and the Administrative Agent (or, in the case of a Participant, to
the Lender from which the related participation shall have been purchased) two
copies of either U.S. Internal Revenue Service form 1001 or Form 4224, or, in
the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding
tax under Section 871(h) or 881(c) of the Code with respect to payments of
"portfolio interest," a Form W-8, or any subsequent versions thereof or
successors thereto (and, if such Non-U.S. Lender delivers a Form W-8, an annual
certificate representing that such Non-U.S. Lender (i) is not a "bank" for
purposes of Section 881(c) of the Code (and is not subject to regulatory or
other legal requirements as a bank in any jurisdiction, and has not been
treated as a bank in any filing with or submission  made to any Governmental
Authority or rating agency), (ii) is not a 10% shareholder (within the meaning
of Section 871(h)(3)(B) of the Code) of the Borrower and (iii) is not a
controlled foreign corporation related to the Borrower (within the meaning of
Section 864(d)(4) of the Code)), properly completed and duly executed by such
Non-U.S. Lender claiming complete exemption from U.S. federal withholding tax
on all payments by the Borrower under this Agreement and the other Loan
Documents, along with such other additional forms as the Borrower, the
Administrative Agent (or, in the case of a Participant, the Lender from which
the related participation shall have been purchased) may reasonably request to
establish the availability of such exemption.  Such forms shall be delivered
<PAGE>   38
                                                                              33

by each Non-U.S. Lender on or before the date it becomes a party to this
Agreement (or, in the case of any Participant, on or before the date such
Participant purchases the related participation).

                 4.14  Indemnity.  The Borrower agrees to indemnify each Lender
and to hold each Lender harmless from any loss or expense which such Lender may
sustain or incur (other than through such Lender's gross negligence or willful
misconduct) as a consequence of (a) default by the Borrower in making a
borrowing of, conversion into or continuation of Eurodollar Loans after the
Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by the Borrower in making any
prepayment of a Eurodollar Loan after the Borrower has given a notice thereof
in accordance with the provisions of this Agreement or (c) the making of a
prepayment of or a conversion of Eurodollar Loans on a day which is not the
last day of an Interest Period with respect thereto.  Such indemnification may
include an amount equal to the excess, if any, of (i) the amount of interest
which would have accrued on the amount so prepaid, or converted, or not so
borrowed, converted or continued, for the period from the date of such
prepayment or conversion or of such failure to borrow, convert or continue to
the last day of the applicable Interest Period (or, in the case of a failure to
borrow, convert or continue, the Interest Period that would have commenced on
the date of such failure) in each case at the applicable rate of interest for
such Eurodollar Loans provided for herein (excluding, however, the percentage
added to the Eurodollar Rate pursuant to subsection 4.1(a) to the extent
included therein) over (ii) the amount of interest (as reasonably determined by
such Lender) which would have accrued to such Lender on such amount by placing
such amount on deposit for a comparable period with leading banks in the
interbank eurodollar market.  This covenant shall survive the termination of
this Agreement and the payment of the Loans and all other amounts payable
hereunder.

                 4.15  Change of Lending Office.  (a)  Each Lender agrees that
if it makes any demand for payment under subsection 4.12 or 4.13(a), or if any
adoption or change of the type described in subsection 4.11 shall occur with
respect to it, it will use reasonable efforts (consistent with its internal
policy and legal and regulatory restrictions and so long as such efforts would
not be disadvantageous to it, as determined in its sole discretion) to
designate a different lending office if the making of such a designation would
reduce or obviate the need for the Borrower to make payments under subsection
4.12 or 4.13(a), or would eliminate or reduce the effect of any adoption or
change described in subsection 4.11.

                 (b)  If any Lender requests compensation under subsection
4.12, or if the Borrower is required to pay any additional amount to any Lender
or any Governmental Authority for the account of any Lender pursuant to
subsection 4.13, or if any Lender defaults in its obligation to fund Loans
hereunder, then the Borrower may, at its expense and effort, upon notice to
such Lender and the Administrative Agent, require such Lender to, and such
Lender promptly shall, assign and delegate, without recourse (in accordance
with and subject to the restrictions contained in subsection 11.6), all its
interests, rights and obligations under this Agreement to an assignee that
shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment); provided that (i) if such assignee is not a
Lender or an Affiliate thereof, the Borrower shall have received the prior
written consents of the Administrative Agent and Issuing Lender which consents
shall not unreasonably be withheld, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of its Loans and
participations in Letters of Credit, accrued interest thereon, accrued fees and
all other amounts payable to it hereunder, from the assignee (at least to the
extent of such outstanding principal) and the Borrower (in the case of all
other amounts) and (iii) in the case of any such assignment resulting from a
claim for compensation under subsection 4.12 or payments required to be made
pursuant to subsection 4.13, such assignment will result in a reduction in such
compensation or payments compared to the compensation or payments payable to
the assigning

Lender.  A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or
otherwise, the circumstances entitling the Borrower to require such assignment
and delegation no longer exist or cease to apply.


                   SECTION 5.  REPRESENTATIONS AND WARRANTIES

                 To induce the Administrative Agent and the Lenders to enter
into this Agreement and to make the Loans and issue or participate in the
Letters of Credit, the Borrower hereby represents and warrants to the
Administrative Agent and each Lender (unless otherwise provided, after giving
effect to the Merger) that:

                 5.1  Financial Condition.  (a)  The consolidated balance
sheets of the Borrower and its consolidated Subsidiaries, and the consolidated
balance sheets of Cairn and its consolidated Subsidiaries, at December 31, 1995
and December 31, 1996 and the related consolidated statements of operations, of
cash flows and of changes in stockholders' equity for the respective fiscal
years ended on such dates, together with the related notes and schedules
thereto, reported on by Ernst & Young LLP, copies of which have heretofore been
furnished to each Lender, present fairly in all material respects the
consolidated financial condition of the Borrower and its consolidated
Subsidiaries, and Cairn and its consolidated Subsidiaries, respectively, as at
such dates, and the consolidated results of their operations and their
consolidated cash flows for the respective fiscal years then ended, in
conformity with GAAP.

                 (b)  The unaudited consolidated balance sheet of the Borrower
and its consolidated Subsidiaries, and the unaudited consolidated balance sheet
of Cairn and its consolidated Subsidiaries, at June 30, 1997 and the related
unaudited consolidated statements of operations, of cash flows and of changes
in stockholders' equity for the 6-month period ended on such dates, together
with the related notes and schedules thereto, certified by a Responsible
Officer, copies of which have heretofore been furnished to each Lender, present
fairly in all material respects the consolidated financial condition of each of
the Borrower and its consolidated Subsidiaries, and Cairn and its consolidated
Subsidiaries, respectively, as at such dates, and the consolidated results of
their respective operations and their consolidated cash flows for the 6-month
period then ended (subject to normal year-end audit adjustments), in conformity
with GAAP.

                 (c)  All such financial statements referred to in subsections
5.1(a) and (b), including the related schedules and notes thereto, have been
prepared in accordance with GAAP applied consistently throughout the periods
involved (except as approved by such accountants or Responsible Officer, as the
case may be, and as disclosed therein).  On the Closing Date, after giving
effect to the Merger, neither the Borrower nor any of its consolidated
Subsidiaries have, at the date of the most recent balance sheet referred to
above, any material Guarantee Obligation, contingent liability or liability for
taxes, or any long-term lease, outstanding debt or Lien or unusual forward or
long-term commitment, including, without limitation, any interest rate or
foreign currency swap or exchange transaction, which (i) is not disclosed in
the financial statements referred to in subsection 5.1(a) or 5.1(b) or in the
notes thereto to the extent required by GAAP or (ii) in the case of the Amoco
Litigation, does not exceed $10,000,000.

                 5.2  No Change.  (a)  Since December 31, 1996, there has been
no development, circumstance or event which has had or could reasonably be
expected to have a Material Adverse Effect (provided that liability or accrued
charges of the Borrower of up to $10,000,000 in connection with the Amoco
Litigation, in and of itself, shall not be deemed to be a violation of this
subsection

                                                                              35

5.2(a)), and (b) during the period from January 1, 1997 to and including the
date hereof, no dividends or other distributions have been declared, paid or
made upon the Capital Stock of the Borrower nor, except as set forth on
Schedule 5.2, has any of the Capital Stock of the Borrower been redeemed,
retired, purchased or otherwise acquired for value by the Borrower or any of
its Subsidiaries.

                 5.3  Corporate Existence; Compliance with Law.  Each of the
Borrower and its Subsidiaries (a) is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization, (b) has
the corporate power and authority, and the legal right, to own and operate its
Property, to lease the Property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of Property or the conduct of its business
requires such qualification except to the extent that the failure to be so
qualified and in good standing could not reasonably be expected to have, in the
aggregate, a Material Adverse Effect and (d) is in compliance with all
applicable Requirements of Law (including, without limitation, Environmental
Laws) except to the extent that the failure to comply therewith could not
reasonably be expected to have, in the aggregate, a Material Adverse Effect.

                 5.4  Corporate Power; Authorization; Enforceable Obligations.
The Borrower and each of the other Loan Parties has the corporate power and
authority, and the legal right, to make, deliver and perform the Loan Documents
to which it is a party and, in the case of the Borrower, to borrow hereunder
and has taken all necessary corporate action to authorize the execution,
delivery and performance of the Loan Documents to which it is a party.  No
consent or authorization of, filing with, notice to or other act by or in
respect of, any Governmental Authority or any other Person is required in
connection with the borrowings hereunder or the delivery, performance, validity
or enforceability of the Loan Documents to which each Loan Party is a party
other than those which have been obtained and are in full force and effect.
This Agreement has been, and each other Loan Document to which any Loan Party
is a party will be, duly executed and delivered on behalf of such Loan Party.
This Agreement constitutes, and each other Loan Document to which any Loan
Party is a party when executed and delivered will constitute, a legal, valid
and binding obligation of such Loan Party enforceable against such Loan Party
in accordance with its terms, subject to the effects of bankruptcy, insolvency,
fraudulent transfer or conveyance, reorganization, moratorium and other similar
laws relating to or affecting creditors' rights generally, general equitable
principles (whether considered in a proceeding in equity or at law) and an
implied covenant of good faith and fair dealing.

                 5.5  No Legal Bar.  The execution, delivery and performance of
the Loan Documents, the granting of the Liens under the Security Documents, the
borrowings hereunder and the use of the proceeds thereof will not violate any
applicable Requirement of Law or Contractual Obligation of the Borrower or of
any of its Subsidiaries and will not result in, or require, the creation or
imposition of any Lien on any of its or their respective Properties or revenues
pursuant to any such Requirement of Law or Contractual Obligation, other than
any Lien created pursuant to the Security Documents.

                 5.6  No Material Litigation.  No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrower, threatened by or against the Borrower or any
of its Subsidiaries or against any of its or their respective Properties or
revenues (a) with respect to any of the Loan Documents or any of the
transactions contemplated hereby or thereby, or (b) which could reasonably be
expected to have a Material Adverse Effect; provided that liability or accrued
charges of the Borrower of up to $10,000,000 in connection with the Amoco
Litigation, in and of itself, shall not be deemed to be a violation of this
subsection 5.6.

                                                                              36


                 5.7  No Default.  Neither the Borrower nor any of its
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect which could reasonably be expected to have a
Material Adverse Effect; provided that liability of the Borrower of up to
$10,000,000 in connection with the Amoco Litigation, in and of itself, shall
not be deemed to be a violation of this subsection 5.7.  No Default or Event of
Default has occurred and is continuing.

                 5.8  Ownership of Property; Liens.  (a)  Except for the Oil
and Gas Properties, the Borrower and its Subsidiaries each have good title in
fee simple to, or a valid leasehold interest in, all its material real Property
and material interests in real Property, and good title to, or a valid
leasehold interest in, all its other material Property, and none of such
Property is subject to any Lien except as permitted by subsection 8.3.

                 (b)  The Borrower and its Subsidiaries each have good and
defensible title to all of its Oil and Gas Properties which are not personal
property and good title to all such Oil and Gas Properties which are personal
property and material to the Borrower and its Subsidiaries taken as a whole,
except for (i) such imperfections of title as do not in the aggregate
materially detract from the value thereof to, or the use thereof in, the
business of the Borrower or any of its Subsidiaries, (ii) Oil and Gas
Properties and interests therein disposed of since the date of the most recent
Reserve Report as permitted by subsection 8.6 hereof, (iii) imperfections of
title relating to the rights of Amoco in the Southwest Holmwood Properties, to
the extent described in the S-4, and(iv) Liens permitted by subsection 8.3
hereof.  The quantum and nature of the interest of the Borrower and its
Subsidiaries in and to the Oil and Gas Properties as set forth in each Reserve
Report (including the Initial Reserve Report) includes the entire interest of
the Borrower and its Subsidiaries in such Oil and Gas Properties as of the date
of such Reserve Report and are complete and accurate in all material respects
as of the date of such Reserve Report; and there are no "back-in" or
"reversionary" interests held by third parties which could materially reduce
the interest of the Borrower and its Subsidiaries in such Oil and Gas
Properties except as expressly set forth in such Reserve Report.  The ownership
of the Oil and Gas Properties by the Borrower and its Subsidiaries shall not in
any material respect obligate any such Person to bear the costs and expenses
relating to the maintenance, development or operations of each such Oil and Gas
Property in an amount in excess of the working interest of such Person in each
Oil and Gas Property set forth in the most recent Reserve Report.

                 5.9  Intellectual Property.  Each of the Borrower and its
Subsidiaries owns, or is licensed to use, all trademarks, tradenames,
copyrights, technology, know-how and processes necessary for the conduct of its
business as currently conducted except for those the failure to own or license
which could not reasonably be expected to have a Material Adverse Effect (the
"Intellectual Property").  No claim has been asserted and is pending by any
Person challenging or questioning the use of any such Intellectual Property or
the validity or effectiveness of any such Intellectual Property, nor does the
Borrower know of any valid basis for any such claim which could reasonably be
expected to have a Material Adverse Effect.  The use of such Intellectual
Property by the Borrower and its Subsidiaries does not infringe on the rights
of any Person, except for such claims and infringements that, in the aggregate,
could not reasonably be expected to have a Material Adverse Effect.

                 5.10  No Burdensome Restrictions.  No applicable Requirement
of Law or Contractual Obligation of the Borrower or any of its Subsidiaries has
had during the last fiscal year of the Borrower, or could reasonable be
expected to have, a Material Adverse Effect.

                 5.11  Taxes.  Each of the Borrower and its Subsidiaries has
filed all material tax returns which, to the knowledge of such Loan Party, are
required to be filed by it and has paid or caused to be paid all taxes shown on
said returns and all assessments, fees and other governmental
<PAGE>   42
                                                                              37

charges levied upon it or upon any of its Property or income which are due and
payable, other than such taxes, assessments, fees and other governmental
charges, if any, as are being diligently contested in good faith and by
appropriate proceedings and with respect to which there have been established
adequate reserves on the books of the Borrower or its Subsidiaries, as the case
may be, in accordance with GAAP.  No tax lien has been filed and, to the
knowledge of the Borrower, no claim is being asserted, with respect to any such
taxes or assessments, fees or other governmental charges.

                 5.12  Federal Reserve Regulations.    No part of the proceeds
of any Loans will be used for "purchasing" or "carrying" any "margin stock"
within the respective meanings of each of the quoted terms under Regulation G
or Regulation U of the Board of Governors of the Federal Reserve System as now
and from time to time hereafter in effect.  If requested by any Lender or the
Administrative Agent, the Borrower will furnish to the Administrative Agent and
each Lender a statement to the foregoing effect in conformity with the
requirements of FR Form G-1 or FR Form U-1 referred to in said Regulation G or
Regulation U, as the case may be.

                 5.13  ERISA.  Neither a Reportable Event nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with the applicable provisions
of ERISA and the Code.  No termination of a Single Employer Plan has occurred,
and no Lien in favor of the PBGC or a Plan has arisen, during such five-year
period.  The present value of all accrued benefits under each Single Employer
Plan (based on those assumptions used to fund such Plans) did not, as of the
last annual valuation date prior to the date on which this representation is
made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits.  Neither the Borrower nor any Commonly Controlled Entity
has had a complete or partial withdrawal from any Multiemployer Plan, and
neither the Borrower nor any Commonly Controlled Entity would become subject to
any liability under ERISA if the Borrower or any such Commonly Controlled
Entity were to withdraw completely from all Multiemployer Plans as of the
valuation date most closely preceding the date on which this representation is
made or deemed made.  No such Multiemployer Plan is in Reorganization or
Insolvent.

                 5.14  Investment Company Act; Other Regulations.  Neither the
Borrower nor any of its Subsidiaries is (a) an "investment company", or a
company "controlled" by an "investment company", within the meaning of the
Investment Company Act of 1940, as amended or (b) a "holding company" as
defined in, or subject to regulation under, the Public Utility Holding Company
Act of 1935.  Neither the Borrower nor any of its Subsidiaries is subject to
regulation under any Federal or State statute or regulation (other than
Regulation X of the Board of Governors of the Federal Reserve System) which
limits its ability to incur Indebtedness.

                 5.15  Subsidiaries.  The Persons listed on Schedule 5.15
constitute all the Subsidiaries of the Borrower and Cairn at the date hereof.

                 5.16  Purpose of Loans.  The proceeds of the Loans and the
Letters of Credit will be used (a) to refinance the Refinanced Indebtedness,
and to pay fees and expenses related to the Merger, on the Closing Date and (b)
after the Closing Date, for working capital and for the general corporate
purposes of the Borrower and its Subsidiaries in the ordinary course of
business.

                 5.17  Environmental Matters.  Other than exceptions to any of
the following that could not, in the aggregate, reasonably be expected to
either (a) result in the existence of an unsatisfied
<PAGE>   43
                                                                              38

liability in excess of a Material Environmental Amount or (b) give rise to a
Material Adverse Effect or materially adversely affect the value of the
Mortgaged Properties taken as a whole:

                 (a)  each of the Borrower and its Subsidiaries:  (i) is, and
         within the period of all applicable statutes of limitation has been,
         in compliance with all applicable Environmental Laws; (ii) holds all
         Environmental Permits (each of which is in full force and effect)
         required for any of its current or planned operations or for any
         Property owned, leased, or otherwise operated by it; (iii) is, and
         within the period of all applicable statutes of limitation has been,
         in compliance with all of its Environmental Permits; and (iv)
         reasonably believes that (A) each of its Environmental Permits will be
         timely renewed without expense, (B) any additional Environmental
         Permits which it has reason to believe will be required will be timely
         obtained without expense, and (C) the costs of complying with such
         renewed or additional Environmental Permits and any other
         Environmental Laws applicable to or reasonably expected to apply to
         the Borrower and its Subsidiaries will not exceed the Borrower's and
         its Subsidiaries' existing costs of complying with Environmental
         Permits and Environmental Laws.

                 (b)  Materials of Environmental Concern have not been
         transported, disposed of, emitted, discharged, or otherwise released
         or threatened to be released, to or at any real Property presently or
         formerly owned, leased or operated by the Borrower or any Subsidiary
         or at any other location, which could reasonably be expected to (i)
         give rise to liability of the Borrower or any Subsidiary under any
         applicable Environmental Law or (ii) interfere with the Borrower's
         continued operations.

                 (c)  no judicial, administrative, or arbitral proceeding
         (including any notice of violation or alleged violation) under or
         relating to any Environmental Law to which the Borrower or any
         Subsidiary is, or to the knowledge of the Borrower will be, named as a
         party is pending or, to the knowledge of the Borrower, threatened.

                 (d)  the Borrower has not received any written request for
         information, or been notified that it or any Subsidiary is a
         potentially responsible party under the federal Comprehensive
         Environmental Response, Compensation, and Liability Act or any similar
         Environmental Law, or with respect to any Materials of Environmental
         Concern.

                 (e)  neither the Borrower nor any Subsidiary has entered into
         or agreed to any consent decree, order, or settlement or other
         agreement, nor is subject to any judgment, decree, or order or other
         agreement, in any judicial, administrative, arbitral, or other forum,
         relating to compliance with or liability under any Environmental Law.

                 (f)  neither the Borrower nor any Subsidiary has assumed or
         retained, by contract or operation of law, any liabilities of any
         kind, fixed, contingent or otherwise, under any Environmental Law.

                 5.18  No Material Misstatements.  (a)  All written
information, reports, financial statements, exhibits and schedules (including,
without limitation, the S-4) furnished to the Administrative Agent or any
Lender by or on behalf of the Borrower or any of its Subsidiaries in connection
with the negotiation of any Loan Document or included therein or delivered
pursuant thereto, when taken as a whole, did not contain, and as they may be
amended, supplemented or
<PAGE>   44
                                                                              39

modified from time to time, will not contain, as of the date such statements
were made, any untrue statements of a material fact and did not omit, and as
they may be amended, supplemented or modified from time to time, will not omit,
to state as of the date such statements were made, any material fact necessary
in order to make the statements contained therein, in the light of the
circumstances under which they were, are or will be made, not materially
misleading.

                 (b)  All projections and estimates concerning the Borrower and
its Subsidiaries that are or have been made available to the Administrative
Agent or any Lender by or on behalf of the Borrower or any of its Subsidiaries
(including, without limitation, the pro forma financial statements included in
the S-4), have been or will be prepared based on good faith estimates and based
upon assumptions believed by the Borrower to be reasonable in all material
respects at the time of such preparation, and the unaudited pro forma combined
balance sheet of the Borrower and Cairn included in the S-4 represents in all
material respects the pro forma consolidated financial condition of the
Borrower and its consolidated Subsidiaries after giving effect to the Merger
and the initial Loans under this Agreement, as if the Merger occurred on June
30, 1997.

                 5.19  Insurance.  Each of the Borrower and its Subsidiaries
carries and maintains with respect to its insurable properties insurance
(including, to the extent consistent with past practices, self-insurance) with
financially sound and reputable insurers of the types, to such extent and
against such risks as is customary with companies in the same or similar
businesses.

                 5.20  Future Commitments.  As of the date hereof and as of the
Closing Date, except as set forth on Schedule 5.20, on a net basis there are no
material gas imbalances, material take-or-pay or other prepayments with respect
to any Oil and Gas Property of the Borrower or any Subsidiary (or, in the case
of Oil and Gas Properties operated by operators other than the Borrower or its
Subsidiaries, to the Borrower's knowledge after reasonable investigation) which
would require the Borrower or any Subsidiary to deliver Hydrocarbons produced
from Oil and Gas Properties at some future time without then or thereafter
receiving full payment therefor.

                 5.21  Security Documents.  (a)  The provisions of the Pledge
Agreement delivered to the Administrative Agent are effective to create in
favor of the Administrative Agent, for the ratable benefit of the Lenders, a
legal, valid and enforceable security interest in the Pledged Securities and
proceeds thereof and, when certificates representing or constituting the
Pledged Securities are delivered to the Administrative Agent, the Pledge
Agreement shall constitute a fully perfected first priority lien on, and
security interest in, all right, title and interest of the pledgor party
therein in such Pledged Securities and the proceeds thereof, in each case prior
and superior in right to any other Person.

                 (b)  On the Closing Date, the shares of Capital Stock listed
on Schedule I to the Pledge Agreement will constitute all the issued and
outstanding shares of Capital Stock of the direct and indirect Subsidiaries of
the Borrower (including Cairn and its Subsidiaries); all such shares have been
duly and validly issued and are fully paid and nonassessable; and the relevant
Pledgor of said shares is the record and beneficial owner of said shares.

                 (c)  The provisions of the Mortgages will be effective to
grant to the Administrative Agent, for the ratable benefit of the Lenders,
legal, valid and enforceable mortgage liens on all of the right, title and
interest of the Borrower and its Subsidiaries (including Cairn and its
Subsidiaries) in the mortgaged property described therein.  Such Mortgages,
when recorded in the appropriate recording office, will constitute perfected
first liens on, and security interest in, such mortgaged property.

                 5.21.  Immaterial Subsidiaries.  The value of the assets owned
by the Immaterial Subsidiaries does not exceed $500,000 in the aggregate.

                        SECTION 6.  CONDITIONS PRECEDENT

                 6.1  Conditions to Initial Extensions of Credit.  The
agreement of each Lender to make the initial Loan requested to be made by it
and of the Issuing Lender to issue the initial Letter of Credit to be issued by
it is subject to the satisfaction, immediately prior to or concurrently with
the making of such Loan and the issuance of such Letter of Credit on the
Closing Date, of the following conditions precedent:

         Administrative Agent) (i) this Agreement, executed and delivered by a
         duly authorized officer of the Borrower, (ii) the Guarantee Agreement,
         executed and delivered by a duly authorized officer of each Loan Party
         thereto, (iii) the Pledge Agreement, executed and delivered by a duly

                 (b)  Related Agreements.  The Administrative Agent shall have
         received true and correct copies, certified as to authenticity by the
         Borrower, of Merger Documents, such other documents or instruments as
         may be reasonably requested by the Administrative Agent, including,
         without limitation, a copy of any debt instrument or security
         agreement to which the Borrower and its Subsidiaries will be a party
         after the Closing Date.

                 (c)  Borrowing Certificate.  The Administrative Agent shall
         have received (with the number of original counterparts requested by
         the Administrative Agent), a certificate of the Borrower, dated the
         Closing Date, substantially in the form of Exhibit F, with appropriate
         insertions and attachments, satisfactory in form and substance to the
         Administrative Agent, executed by a Responsible Officer of the

         Administrative Agent shall have received (with the number of original
         counterparts requested by the Administrative Agent), a copy of the
         resolutions, in form and substance satisfactory to the Administrative
         Agent, of the Board of Directors of each Loan Party authorizing (i)

         Documents to which it is a party, (ii) in the case of the Borrower,
         the borrowings contemplated hereunder and (iii) the granting by it of
         the Liens created pursuant to the Loan Documents, certified by the

         reasonably satisfactory to the Administrative Agent and shall state
         that the resolutions thereby certified have not been amended,
         modified, revoked or rescinded.

                 (e)  Loan Party Incumbency Certificates.  The Administrative

                          (b)  Comply in all material respects with all

         or appropriate repairs, renewals, replacements, additions and
         improvements thereto so that the efficiency of the operating equipment
         shall at all times be properly preserved and maintained, provided that
         no item of operating equipment need be so repaired, renewed, replaced,
         added to or improved, if Borrower or its Subsidiaries shall in good
         faith determine that the action is not necessary or desirable for such
         Person's continued efficient and profitable operation of business.

         Oil and Gas Properties of the Borrower or its Subsidiaries ceases
         producing Hydrocarbons in paying quantities and is of no further use
         and the Borrower or any other Person is required to do so under any
         agreement or law or when doing so would be in conformity with
         generally accepted practices then prevalent in the Borrower's
         industry, the Borrower will plug and abandon, or cause to be plugged
         and abandoned, any and all such wells in accordance in all material
         respects with industry practice and the local state and/or federal
         laws and regulations then in force and regulating the plugging of
         Hydrocarbon wells.

Administrative Agent, promptly perform or cause to be performed any and all
acts and execute or cause to be executed any and all documents (including,

Requirement of Law which are necessary or advisable to maintain in favor of the
Administrative Agent, for the benefit of the Lenders, Liens on the Pledged
Securities and on the Oil and Gas Properties subject to the Mortgages that are
duly perfected in accordance with all applicable Requirements of Law; provided
that the Liens created by such Mortgages shall be released after the end of the
Initial Period (pursuant to documentation reasonably satisfactory to the
Administrative Agent) if, at such time, (x) no Default or Event of Default has
occurred and is continuing and (y) the Borrower has made any mandatory
prepayment required by subsection 4.10 to be made within 60 days after the

or any officer thereof contained in this Agreement or any other Loan Document
or in any certificate, report, statement or other document referred to or
provided for in, or received by the Administrative Agent under or in connection
with, this Agreement or any other Loan Document or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document or for any failure of any Loan Party to perform its
<PAGE>   65
                                                                              60

obligations hereunder or thereunder.  The Administrative Agent shall not be
under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of any Loan Party.

                 10.4  Reliance by Administrative Agent.  The Administrative
Agent shall be entitled to rely, and shall be fully protected in relying, upon
any Note, writing, resolution, notice, consent, certificate, affidavit, letter,
telecopy, telex or teletype message, statement, order or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of
legal counsel (including, without limitation, counsel to the Loan Parties),
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat the payee of any Note as the owner
thereof for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Administrative Agent.  The
Administrative Agent shall be fully justified in failing or refusing to take
any action under this Agreement or any other Loan Document unless it shall
first receive such advice or concurrence of the Required Lenders (or, where
unanimous consent of the Lenders is expressly required hereunder, such Lenders)
as it deems appropriate or it shall first be indemnified to its satisfaction by
the Lenders against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action.  The
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement and the other Loan Documents in
accordance with a request of the Required Lenders (or, where unanimous consent
of the Lenders or the Supermajority Lenders is expressly required hereunder,
such Lenders or Supermajority Lenders, as applicable), and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and all future holders of the Loans.

                 10.5  Notice of Default.  The Administrative Agent shall not
be deemed to have knowledge or notice of the occurrence of any Default or Event
of Default hereunder unless the Administrative Agent has received notice from a
Lender or the Borrower referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default".  In the
event that the Administrative Agent receives such a notice, the Administrative
Agent shall give notice thereof to the Lenders.  The Administrative Agent shall
take such action with respect to such Default or Event of Default as shall be
reasonably directed by the Required Lenders; provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it
shall deem advisable in the best interests of the Lenders.

                 10.6  Non-Reliance on Administrative Agent and Other Lenders.
Each Lender expressly acknowledges that neither the Administrative Agent nor
any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates has made any representations or warranties to it and that no act by
the Administrative Agent hereafter taken, including any review of the affairs
of any Loan Party, shall be deemed to constitute any representation or warranty
by the Administrative Agent to any Lender.  Each Lender represents to the
Administrative Agent that it has, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of each Loan Party and made its own decision to
make its Extensions of Credit hereunder and enter into this Agreement.  Each
Lender also represents that it will, independently and without reliance upon
the Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigation as
it
<PAGE>   66
                                                                              61

deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of each Loan Party.  Except
for notices, reports and other documents expressly required to be furnished to
the Lenders by the Administrative Agent hereunder, the Administrative Agent
shall not have any duty or responsibility to provide any Lender with any credit
or other information concerning the business, operations, property, condition
(financial or otherwise), prospects or creditworthiness of any Loan Party which
may come into the possession of the Administrative Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

                 10.7  Indemnification.  The Lenders agree to indemnify the
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrower and without limiting the obligation the Borrower to do so),
ratably according to their respective Commitment Percentages in effect on the
date on which indemnification is sought, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind whatsoever which may at any
time (including, without limitation, at any time following the payment of the
obligations under this Agreement) be imposed on, incurred by or asserted
against the Administrative Agent in any way relating to or arising out of, the
Commitments, this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the
Administrative Agent under or in connection with any of the foregoing; provided
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting solely from the
Administrative Agent's gross negligence or willful misconduct.  The agreements
in this subsection shall survive the payment of all obligations under this
Agreement and all other amounts payable hereunder.

                 10.8  Administrative Agent in Its Individual Capacity.  The
Administrative Agent and its Affiliates may make loans to, accept deposits from
and generally engage in any kind of business with any Loan Party as though the
Administrative Agent were not the Administrative Agent hereunder and under the
other Loan Documents.  With respect to the Extensions of Credit made by it, the
Administrative Agent shall have the same rights and powers under this Agreement
and the other Loan Documents as any Lender and may exercise the same as though
it were not the Administrative Agent, and the terms "Lender" and "Lenders"
shall include the Administrative Agent in its individual capacity.

                 10.9  Successor Administrative Agent.  The Administrative
Agent may resign as Administrative Agent upon 30 days' notice to the Lenders.
If the Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Loan Documents, then the Required Lenders shall appoint
from among the Lenders a successor agent for the Lenders, which successor
agent, with the consent of the Borrower (such consent not to be unreasonably
withheld or delayed), shall succeed to the rights, powers and duties of the
Administrative Agent hereunder.  Effective upon such appointment and approval,
the term "Administrative Agent" shall mean such successor agent, and the former
Administrative Agent's rights, powers and duties as Administrative Agent shall
be terminated, without any other or further act or deed on the part of such
former Administrative Agent or any of the parties to this Agreement or any
holders of the Loans.  After any retiring Administrative Agent's resignation as
Administrative Agent, the provisions of this Section 10 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement and the other Loan Documents.

                 10.10  Issuing Lender.  The provisions of this Section 10
applicable to the Administrative Agent shall apply to the Issuing Lender in the
performance of its duties under the Loan Documents, mutatis mutandis.

                           SECTION 11.  MISCELLANEOUS

                 11.1  Amendments and Waivers.  Neither this Agreement nor any
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
subsection. The Required Lenders may, or, with the written consent of the
Required Lenders, the Administrative Agent may, from time to time, (a) enter
into with the applicable Loan Parties written amendments, supplements or
modifications hereto and to the other Loan Documents for the purpose of adding
any provisions to this Agreement or the other Loan Documents or changing in any
manner the rights of the Lenders or of the applicable Loan Parties hereunder or
thereunder or (b) waive, on such terms and conditions as the Required Lenders
or the Administrative Agent, as the case may be, may specify in such
instrument, any of the requirements of this Agreement or the other Loan
Documents or any Default or Event of Default and its consequences; provided,
however, that no such waiver and no such amendment, supplement or modification
shall (i) reduce the amount, or extend the scheduled date of final maturity, of
any Loan, or reduce the stated rate of any interest or fee payable hereunder or
extend the scheduled date of any payment thereof or increase the amount or
extend the expiration date of any Lender's Commitments, in each case without
the consent of each Lender affected thereby, or (ii) amend, modify or waive any
provision of this subsection or reduce the percentage specified in the
definition of Required Lenders or Supermajority Lenders (or modify any
provision of this Agreement or any other Loan Document to provide that an
action currently requiring the approval of or consent by the Supermajority
Lenders may be taken with the consent or approval by a lower percentage of
Lenders), or consent to the assignment or transfer by any Loan Party of any of
its rights and obligations under this Agreement and the other Loan Documents
other than in accordance with the terms of the applicable Loan Documents, in
each case without the written consent of all the Lenders, (iii) release, or
subordinate the interest of the Administrative Agent in, all or substantially
all of the collateral for the obligations hereunder or release all or
substantially all of the Guarantors from their respective obligations under the
Guarantee Agreement without the written consent of each Lender, (iv) change
subsection 4.8(a) or subsection 11.7(a) in a manner that would alter the pro
rata sharing of payments required thereby, without the written consent of each
Lender, or (v) amend, modify or waive any provision of Section 10 without the
written consent of the then Administrative Agent and Issuing Lender.  Any such
waiver and any such amendment, supplement or modification shall apply equally
to each of the Lenders and shall be binding upon the Loan Parties, the Lenders,
the Administrative Agent and all future holders of the Loans.  In the case of
any waiver, the Loan Parties, the Lenders and the Administrative Agent shall be
restored to their former positions and rights hereunder and under the other
Loan Documents, and any Default or Event of Default waived shall be deemed to
be cured and not continuing; no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

                 11.2  Notices.  All notices, requests and demands to or upon
the respective parties hereto to be effective shall be in writing (including by
facsimile transmission) and, unless otherwise expressly provided herein, shall

provided that any notice, request or demand to or upon the Administrative Agent

effective until received.

                 11.3  No Waiver; Cumulative Remedies.  No failure to exercise
and no delay in exercising, on the part of the Administrative Agent, the
Issuing Lender or any Lender, any right, remedy, power or privilege hereunder
or under the other Loan Documents shall operate as a waiver thereof; nor shall
any single or partial exercise of any right, remedy, power or privilege
hereunder preclude any other or further exercise thereof or the exercise of any
other right, remedy, power or privilege.  The rights, remedies, powers and
privileges herein provided are cumulative and not exclusive of any rights,
remedies, powers and privileges provided by law.

                 11.4  Survival of Representations and Warranties.  All
representations and warranties made hereunder, in the other Loan Documents and

to pay or reimburse the Administrative Agent and its Affiliates for all their
reasonable and documented out-of-pocket costs and expenses incurred in
connection with the development, syndication, preparation and execution of, and
any amendment, supplement or modification to, this Agreement and the other Loan
Documents and any other documents prepared in connection herewith or therewith,
and the consummation and administration of the transactions contemplated hereby
and thereby, including, without limitation,
<PAGE>   69
                                                                              64

the reasonable fees and disbursements of (i) counsel to the Administrative
Agent and (ii) the Administrative Agent customarily charged by it in connection
with syndicated credits, (b) to pay or reimburse each Lender and the
Administrative Agent for all its reasonable and documented costs and expenses
incurred in connection with the enforcement or preservation of any rights under
this Agreement, the other Loan Documents and any such other documents,
including, without limitation, the reasonable fees and disbursements of counsel
to the Administrative Agent and to the several Lenders, (c) to pay, indemnify,
and hold each Lender and the Administrative Agent (and their respective
Affiliates and their respective directors, officers, employees and agents)
harmless from, any and all recording and filing fees and any and all
liabilities with respect to, or resulting from any delay in paying, stamp,
excise and other taxes, if any, which may be payable or determined to be
payable in connection with the execution and delivery of, or consummation or
administration of any of the transactions contemplated by, or any amendment,
supplement or modification of, or any waiver or consent under or in respect of,
this Agreement, the other Loan Documents and any such other documents, and (d)
to pay, indemnify, and hold each Lender, the Administrative Agent (and their
respective directors, officers, employees, agents and affiliates) harmless from
and against any and all other liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Agreement, the other Loan Documents or
the use or the proposed use of proceeds contemplated by this Agreement,
including, without limitation, any of the foregoing relating to the violation
of, noncompliance with or liability under, any Environmental Law applicable to
any Loan Party or any of the Properties (all the foregoing in this clause (d),
collectively, the "indemnified liabilities"), provided that the Borrower shall
have no obligation under this clause (d) to any Administrative Agent or any
Lender (or any of their respective directors, officers, employers, agents or
affiliates), with respect to indemnified liabilities to the extent such
liabilities are determined by a court of competent jurisdiction by final and
nonappealable judgment to have resulted from the gross negligence or willful
misconduct of such Person.  Without limiting the foregoing, and to the extent
permitted by applicable law, the Borrower agrees not to assert, and hereby
waives, and agrees to cause each of its Subsidiaries not to assert and to so
waive, all rights for contribution or any other rights of recovery with respect
to all claims, demands, penalties, fines, liabilities, settlements, damages,
costs and expenses of whatever kind or nature, under or related to
Environmental Laws, that any of them might have by statute or otherwise against
any Person entitled to indemnification under this subsection 11.5.  The
agreements in this subsection shall survive repayment of the Loans and all
other amounts payable hereunder and the termination of this Agreement.

                 11.6  Successors and Assigns; Participations and Assignments.
(a)  This Agreement shall be binding upon and inure to the benefit of the
Borrower, the Lenders, the Administrative Agent, all future holders of the
Loans and any Notes hereunder and their respective successors and assigns,
except that the Borrower may not assign or transfer any of its rights or
obligations under this Agreement without the prior written consent of each
Lender.

                 (b)  Any Lender may, in the ordinary course of its commercial
banking or lending business and in accordance with applicable law and at no
cost or expense to the Borrower, at any time sell to one or more banks or other
entities ("Participants") participating interests in any Loan owing to such
Lender, any Commitment of such Lender or any other interest of such Lender
hereunder and under the other Loan Documents.  In the event of any such sale by
a Lender of a participating interest to a Participant, (i) such Lender's
obligations under this Agreement to the other parties to this Agreement shall
remain unchanged, (ii) such Lender shall remain solely responsible for the
performance thereof, (iii) such Lender shall remain the holder of any such Loan
(and any Note evidencing such Loan) for all purposes under this Agreement and
the other Loan Documents, (iv) the Borrower and the Administrative Agent shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement and the other Loan
Documents, and (v) in any proceeding under the Bankruptcy Code the Lender shall
be, to the extent permitted by law, the sole representative with respect to the
obligations held in the name of such Lender, whether for its own account or for
the account of any Participant.  No Lender shall be entitled to create in favor
of any Participant, in the participation agreement pursuant to which such
<PAGE>   70
                                                                              65

Participant's participating interest shall be created or otherwise, any right
to vote on, consent to or approve any matter relating to this Agreement or any
other Loan Document except for those specified in clauses (i) and (ii) of the
proviso to subsection 11.1.  The Borrower agrees that each Participant shall be
entitled to the benefits of subsections 4.13 and 4.14 with respect to its
participation in the Commitments and the Loans and Letters of Credit
outstanding from time to time as if it was a Lender; provided that, in the case
of subsection 4.13, such Participant shall have complied with the requirements
of said subsection and provided, further, that no Participant shall be entitled
to receive any greater amount pursuant to any such subsection than the
transferor Lender would have been entitled to receive in respect of the amount
of the participation transferred by such transferor Lender to such Participant
had no such transfer occurred.

                 (c)  Any Lender may, in the ordinary course of its commercial
banking or lending business and in accordance with applicable law, at any time
and from time to time assign to any Lender or, with the prior consent of each
Issuing Lender, any Affiliate thereof or, with the prior written consent of the
Administrative Agent, the Borrower and each Issuing Lender (which in each case
shall not be unreasonably withheld), to an additional bank or financial
institution or other entity (an "Assignee") all or any part of its rights and
obligations under this Agreement and the other Loan Documents including,
without limitation, its Revolving Credit Commitments, L/C Commitments,
Revolving Credit Loans and L/C Participating Interests, pursuant to an
Assignment and Acceptance, substantially in the form of Exhibit G, executed by
such Assignee, such assigning Lender (and, in the case of an Assignee that is
not then a Lender, by the Borrower,  the Administrative Agent and each Issuing
Lender) and delivered to the Administrative Agent for its acceptance and
recording in the Register, provided that (i) (unless the Borrower and the
Administrative Agent otherwise consent in writing) no such transfer to an
Assignee (other than a Lender or any Affiliate thereof) shall be in an
aggregate principal amount less than $5,000,000 in the aggregate (or, if less,
the full amount of such assigning Lender's Revolving Credit Loans, L/C
Participating Interests and Revolving Credit Commitments) and (ii) if any
Lender assigns all or any part of its rights and obligations under this
Agreement to one of its Affiliates in connection with or in contemplation of
the sale or other disposition of its interest in such Affiliate, the Borrower's
prior written consent shall be required for such assignment.  Upon such
execution, delivery, acceptance and recording, from and after the effective
date determined pursuant to such Assignment and Acceptance, (x) the Assignee
thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender
hereunder with a Revolving Credit Commitment and L/C Commitment as set forth
therein, and (y) the assigning Lender thereunder shall, to the extent provided
in such Assignment and Acceptance, be released from its obligations under this
Agreement (and, in the case of an Assignment and Acceptance covering all or the
remaining portion of an assigning Lender's rights and obligations under this
Agreement, such assigning Lender shall cease to be a party hereto).
Notwithstanding any provision of this paragraph (c) and paragraph (e) of this
subsection, the consent of the Borrower shall not be required, and, unless
requested by the Assignee and/or the assigning Lender, new Notes shall not be
required to be executed and delivered by the Borrower, for any assignment which
occurs at any time when any of the events described in Section 9(f) shall have
occurred and be continuing.

                 (d)  The Administrative Agent, on behalf of the Borrower,
shall maintain at the address of the Administrative Agent referred to in
subsection 11.2 a copy of each Assignment and Acceptance delivered to it and a
register (the "Register") for the recordation of the names and addresses of the
Lenders and the Commitments of, and principal amounts of the Loans owing to,
each Lender from time to time.  The entries in the Register shall be
conclusive, in the absence of manifest error, and the Borrower, the
Administrative Agent and the Lenders may (and, in the case of any Loan or other
obligation hereunder not evidenced by a Note, shall) treat each Person whose
name is
<PAGE>   71
                                                                              66

recorded in the Register as the owner of a Loan or other obligation hereunder
as the owner thereof for all purposes of this Agreement and the other Loan
Documents, notwithstanding any notice to the contrary.  Any assignment of any
Loan or other obligation hereunder not evidenced by a Note shall be effective
only upon appropriate entries with respect thereto being made in the Register.
The Register shall be available for inspection by the Borrower or any Lender at
any reasonable time and from time to time upon reasonable prior notice.

                 (e)  Notwithstanding anything in this Agreement to the
contrary, no assignment under subsection 11.6(c) of any rights or obligations
under or in respect of the Loans, the Notes or the Letters of Credit shall be
effective unless and until the Administrative Agent shall have recorded the
assignment pursuant to subsection 11.6(d).  Upon its receipt of an Assignment
and Acceptance executed by an assigning Lender and an Assignee (and, in the
case of an Assignee that is not then a Lender or an affiliate thereof, by the
Borrower and the Administrative Agent) together with payment to the
Administrative Agent of a registration and processing fee of $3,500 (other than
in the case of an assignment by a Lender to an affiliate of such Lender), the
Administrative Agent shall (i) promptly accept such Assignment and Acceptance
and (ii) on the effective date determined pursuant thereto record the
information contained therein in the Register and give notice of such
acceptance and recordation to the Lenders and the Borrower.  On or prior to
such effective date, the assigning Lender shall surrender any outstanding Notes
held by it all or a portion of which are being assigned, and the Borrower, at
its own expense, shall, upon the request to the Administrative Agent by the
assigning Lender or the Assignee, as applicable, execute and deliver to the
Administrative Agent (in exchange for the outstanding Notes of the assigning
Lender) a new Revolving Credit Note to the order of such Assignee in an amount
equal to the lesser of (A) the amount of such Assignee's Revolving Credit
Commitment and (B) the aggregate principal amount of all Revolving Credit Loans
made by such Assignee, after giving effect to such Assignment and Acceptance
and, if the assigning Lender has retained a Revolving Credit Commitment
hereunder, a new Revolving Credit Note to the order of the assigning Lender in
an amount equal to the lesser of (A) the amount of such Lender's Revolving
Credit Commitment and (B) the aggregate principal amount of all Revolving
Credit Loans made by such Lender, after giving effect to such Assignment and
Acceptance.  Any such new Notes shall be dated the Closing Date and shall
otherwise be in the form of the Note replaced thereby.  Any Notes surrendered
by the assigning Lender shall be returned by the Administrative Agent to the
Borrower marked "canceled".

                 (f)  The Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee,
any and all financial information in such Lender's possession concerning the
Loan Parties and their Affiliates which has been delivered to such Lender by or
on behalf of the Borrower pursuant to this Agreement or which has been
delivered to such Lender by or on behalf of the Borrower in connection with
such Lender's credit evaluation of the Loan Parties and their Affiliates prior
to becoming a party to this Agreement.

                 (g)  For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this subsection concerning assignments of
Loans and Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests, including, without
limitation, any pledge or assignment by a Lender of any Loan or Note to any
Federal Reserve Bank in accordance with applicable law.

                 11.7  Adjustments; Set-off.  (a)  If any Lender (a "Benefitted
Lender") shall at any time receive any payment of all or part of its Loans or
Reimbursement Obligations, or interest thereon, or receive any collateral in
respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to
events or proceedings of the nature referred to in Section 9(f), or otherwise),
in a greater proportion

                                                                              67

than any such payment to or collateral received by any other Lender, if any, in
respect of such other Lender's Loans or Reimbursement Obligations, or interest
thereon, such Benefitted Lender shall purchase for cash from the other Lenders
a participating interest in such portion of each such other Lender's Loans or
Reimbursement Obligations, or shall provide such other Lenders with the
benefits of any such collateral, or the proceeds thereof, as shall be necessary
to cause such Benefitted Lender to share the excess payment or benefits of such
collateral or proceeds ratably with each of the Lenders; provided, however,
that if all or any portion of such excess payment or benefits is thereafter
recovered from such Benefitted Lender, such purchase shall be rescinded, and
the purchase price and benefits returned, to the extent of such recovery, but
without interest.

                 (b)  In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Borrower hereunder (whether at the stated maturity, by acceleration or
otherwise) to set-off and appropriate and apply against such amount any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender or any branch or agency
thereof to or for the credit or the account of the Borrower, as the case may
be.  Each Lender agrees promptly to notify the Borrower and the Administrative
Agent after any such set-off and application made by such Lender, provided
that, to the extent permitted by applicable law, the failure to give such
notice shall not affect the validity of such set-off and application.

                 11.8  Counterparts.  This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts
(including by facsimile transmission), and all of said counterparts taken
together shall be deemed to constitute one and the same instrument.  A set of
the copies of this Agreement signed by all the parties shall be lodged with the
Borrower and the Administrative Agent.

                 11.9  Severability.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                 11.10  Integration.  This Agreement and the other Loan
Documents represent the agreement of the Borrower, the other Loan Parties, the
Administrative Agent and the Lenders with respect to the subject matter hereof,
and there are no promises, undertakings, representations or warranties by the
Administrative Agent or any Lender relative to subject matter hereof not
expressly set forth or referred to herein or in the other Loan Documents.

                 11.11  GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                 11.12  Submission To Jurisdiction; Waivers.  The Borrower
hereby irrevocably and unconditionally:

                                                                              68


                 (a)  submits for itself and its property in any legal action
         or proceeding relating to this Agreement and the other Loan Documents
         to which it is a party, or for recognition and enforcement of any
         judgment in respect thereof, to the non-exclusive general jurisdiction
         of the Courts of the State of New York, the courts of the United
         States of America for the Southern District of New York, and appellate
         courts from any thereof;

                 (b)  consents that any such action or proceeding may be
         brought in such courts and waives any objection that it may now or
         hereafter have to the venue of any such action or proceeding in any
         such court or that such action or proceeding was brought in an
         inconvenient court and agrees not to plead or claim the same;

                 (c)  agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail), postage
         prepaid, to the Borrower at its address set forth in subsection 11.2
         or at such other address of which the Administrative Agent shall have
         been notified pursuant thereto;

                 (d)  agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or
         shall limit the right to sue in any other jurisdiction; and

                 (e)  waives, to the maximum extent not prohibited by law, any
         right it may have to claim or recover in any legal action or
         proceeding referred to in this subsection any special, exemplary,
         punitive or consequential damages.

                 11.13  Acknowledgments.  The Borrower hereby acknowledges
that:

                 (a)  it has been advised by counsel in the negotiation,
         execution and delivery of this Agreement and the other Loan Documents;

                 (b)  neither the Administrative Agent nor any Lender has any
         fiduciary relationship with or duty to the Borrower arising out of or
         in connection with this Agreement or any of the other Loan Documents,
         and the relationship between Administrative Agent and Lenders, on one
         hand, and the Borrower, on the other hand, in connection herewith or
         therewith is solely that of debtor and creditor; and

                 (c)  no joint venture is created hereby or by the other Loan
         Documents or otherwise exists by virtue of the transactions
         contemplated hereby among the Lenders or among the Borrower and the
         Lenders.

                 11.14  WAIVERS OF JURY TRIAL.  THE BORROWER, THE
ADMINISTRATIVE AGENT AND THE LENDERS HEREBY KNOWINGLY AND INTENTIONALLY,
IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR
PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY
COUNTERCLAIM THEREIN.

                 11.15  Production Proceeds.  Notwithstanding that, by the
terms of the Mortgages, Cairn is and will be assigning to the Administrative
Agent and Lenders all of the "Production Proceeds" (as defined in the Mortgage)
accruing to the property covered thereby, so long as no Event of Default has
occurred Cairn may continue to receive from the purchasers of production all
such Production Proceeds, and the Administrative Agent shall reasonably
cooperate with Cairn so that the purchasers of production pay such Production
Proceeds directly to Cairn and not to the Administrative
<PAGE>   74
                                                                              69

Agent nor the Lenders.  Upon the occurrence and continuation of an Event of
Default, the Administrative Agent and Lenders may exercise all rights and
remedies granted under the Mortgages, including the right to obtain possession
of all Production Proceeds then held by Cairn or to receive directly from the
purchasers of production all other Production Proceeds.  In no case shall any
failure, whether purposed or inadvertent, by the Administrative Agent or
Lenders to collect directly any such Production Proceeds constitute in any way
a waiver, remission or release of any of their rights under the Mortgages, nor
shall any release of any Production Proceeds by Administrative Agent or Lenders
to Cairn constitute a waiver, remission, or release of any other Production
Proceeds or of any rights of Administrative Agent or Lenders to collect other
Production Proceeds thereunder.


                 11.16  Release of Mortgaged Properties.  The Administrative
Agent is hereby authorized by the Lenders to execute, at the cost and expense
of the Borrower and pursuant to documentation reasonably acceptable to the
Administrative Agent, partial releases of the Mortgaged Properties to the
extent such Mortgaged Properties are sold in accordance with the terms of the
Mortgage and subsection 8.6.

                 11.17  Limitation on Interest.  The Borrower, the Loan
Parties, the Administrative Agent and the Lenders intend to contract in strict
compliance with applicable usury law from time to time in effect.  In
furtherance thereof such persons stipulate and agree that none of the terms and
provisions contained in the Loan Documents shall ever be construed to provide
for interest in excess of the maximum amount of interest permitted to be
charged by applicable law from time to time in effect.  Neither any Loan Party
nor any present or future guarantors, endorsers, or other Persons hereafter
becoming liable for payment of any Obligation shall ever be liable for unearned
interest thereon or shall ever be required to pay interest thereon in excess of
the maximum amount that may be lawfully charged under applicable law from time
to time in effect, and the provisions of this section shall control over all
other provisions of the Loan Documents which may be in conflict or apparent
conflict herewith.  The Administrative Agent and the Lenders expressly disavow
any intention to charge or collect excessive unearned interest or finance
charges in the event the maturity of any Obligation is accelerated. If (a) the
maturity of any Obligation is accelerated for any reason, (b) any Obligation is
prepaid and as a result any amounts held to constitute interest are determined
to be in excess of the legal maximum, or (c) any Lender or may other holder of
any or all of the Obligations shall otherwise collect moneys which are
determined to constitute interest which would otherwise increase the interest
on any or all of the Obligations to an amount in excess of that permitted to be
charged by applicable law then in effect, then all sums determined to
constitute interest in excess of such legal limit shall, without penalty, be
promptly applied to reduce the then outstanding principal of the related
Obligations or, at such Lender's or holder's option, promptly returned to
Borrower or the other payor thereof upon such determination.  In determining
whether or not the interest paid or payable, under any specific circumstance,
exceeds the maximum amount permitted under applicable law, Lenders, the
Administrative Agent and the Loan Parties (and any other payers thereof) shall
to the greatest extent permitted under applicable law, (i) characterize any
non-principal payment as an expense, fee or premium rather than as interest,
(ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate, and spread the total amount of interest throughout the
entire contemplated term of the instruments evidencing the Obligations in
accordance with the amounts outstanding from time to time thereunder and the
maximum legal rate of interest from time to time in effect under applicable law
in order to lawfully charge the maximum amount of interest permitted under
applicable law.

reclassification, increase or reduction of capital or any certificate issued in
connection with any reorganization), option or rights, whether in addition to,
in substitution of, as a conversion of, or in exchange for any shares of the
Pledged Stock, or otherwise in respect thereof, such Pledgor shall accept the
same as the agent of the Administrative Agent and the Lenders, hold the same in
trust for the Agent and the Lenders and deliver the same forthwith to the Agent
in the exact form received, duly indorsed by such Pledgor to the Administrative
Agent, if required, together with an undated stock power covering such
certificate duly executed in blank by such Pledgor and with, if the
Administrative Agent so requests, signature guaranteed, to be held by the
Administrative Agent, subject to the terms hereof, as additional collateral
security for the Secured Obligations.  Any sums paid upon or in respect of the
Pledged Stock upon the liquidation or dissolution of any Issuer shall be paid
over to the Administrative Agent to be held by it hereunder as additional
collateral security for the Secured Obligations, and in case any distribution of
capital shall be made on or in respect of the Pledged Stock or any property
shall be distributed upon or with respect to the Pledged Stock pursuant to the
recapitalization or reclassification of the capital of any Issuer or pursuant to
the reorganization thereof, the property so distributed shall be delivered to
the Administrative Agent to be held by it hereunder as additional collateral
security for the Secured Obligations.  If any sums of money or property so paid
or distributed in respect of the Pledged Stock shall be received by such
Pledgor, such Pledgor shall, until such money or property is paid or delivered
to the Administrative Agent, hold such money or property in trust for the
Lenders, segregated from other funds of such Pledgor, as additional collateral
security for the Secured Obligations.

         (b)  Without the prior written consent of the Administrative Agent,
such Pledgor shall not (1) vote to enable, or take any other action to permit,
any Issuer to issue any stock or other equity securities of any nature or to
issue any other securities convertible into or granting the right to purchase
or exchange for any stock or other equity securities of any nature of any
Issuer, (2) sell, assign, transfer, exchange, or otherwise dispose of, or grant
any option with respect to, the Collateral, (3) create, incur or permit to
exist any Lien or option in favor of, or any claim of any Person with respect
to, any of the Collateral, or any interest therein, except for the security
interests created by this Agreement or (4) enter into any agreement or

time and from time to time, upon the written request of the Administrative
Agent, and at the sole expense of such Pledgor, such Pledgor will promptly and
duly execute and deliver such further instruments and documents and take such
further actions as the Administrative Agent may reasonably request for the
purposes of obtaining or preserving the full benefits of this Agreement and of
the rights and powers herein granted.  If any amount payable under or in
connection with any of the Collateral shall be or become evidenced by any
promissory note, other instrument or chattel paper, such note, instrument or
chattel paper shall be immediately delivered to the Administrative Agent, duly
endorsed in a manner satisfactory to the Administrative Agent, to be held as
Collateral pursuant to this Agreement.

         (d)  Such Pledgor shall pay, and save the Administrative Agent and the
Lenders harmless from, any and all liabilities with respect to, or resulting
from any delay in paying, any and all stamp, excise, sales or other taxes which
may be payable or determined to be payable with respect to any of the
Collateral or in connection with any of the transactions contemplated by this
Agreement.

         6.  Cash Dividends; Voting Rights.  Unless an Event of Default shall
have occurred and be continuing and the Administrative Agent shall have given
notice to a Pledgor or Pledgors of the Administrative Agent's intent to
exercise its corresponding rights pursuant to Section 7 below, all Pledgors
shall be permitted to receive all cash dividends paid in the normal course of
business of the Issuers, to the extent permitted in the Credit Agreement, in
respect of the Pledged Stock and to exercise all voting and corporate rights
with respect to the Pledged Stock; provided, however, that no vote shall be
cast or corporate right exercised or other action taken which, in the
Administrative Agent's reasonable judgment, would impair the Collateral or
which would be inconsistent with or result in any violation of any provision of
the Credit Agreement, the Notes, this Agreement or any other Loan Document.

         7.  Rights of the Lenders and the Administrative Agent.  (a)  All
money Proceeds received by the Administrative Agent hereunder shall be held by
the Administrative Agent for the benefit of the Lenders in a Collateral
Account.  All Proceeds while held by the Administrative Agent in a Collateral
Account (or by a Pledgor in trust for the Administrative Agent and the Lenders)
shall continue to be held as collateral security for all the Secured
Obligations and shall not constitute payment thereof until applied as provided
in paragraph 8(a).

         (b)  If an Event of Default shall occur and be continuing and the
Administrative Agent shall give notice of its intent to exercise such rights to
the relevant Pledgor or Pledgors, (1) the Administrative Agent shall have the
right to receive any and all cash dividends paid in respect of the Pledged
Stock and make application thereof to the Secured Obligations in such order as
the Administrative Agent may determine, and (2) all shares of the Pledged Stock
shall be registered in the name of the Administrative Agent or its nominee, and
the Administrative Agent or its nominee may thereafter exercise (A) all voting,
corporate and other rights pertaining to such shares of the Pledged Stock at
any meeting of shareholders of the applicable Issuer or Issuers or otherwise
and (B) any and all rights of conversion, exchange, subscription and any other
rights, privileges or options pertaining to such shares of the Pledged Stock as
if it were the absolute owner thereof (including, without limitation, the right
to exchange at its discretion any and all of the Pledged Stock upon the merger,
consolidation, reorganization, recapitalization or other fundamental change in
the corporate structure of such Issuer, or upon the exercise by such Pledgor or
the Administrative Agent of any right, privilege or option pertaining to such
shares of the Pledged Stock, and in connection therewith, the right to deposit
and deliver any and all of the Pledged Stock with any committee, depositary,
transfer agent, registrar or other designated agency upon such terms and
conditions as the Administrative Agent may determine), all without liability
except to account for property actually received by it, but the Administrative
Agent shall have no duty to such Pledgor to exercise any such right, privilege
or option and shall not be responsible for any failure to do so or delay in so
doing.

         8.  Remedies.  (a)  If an Event of Default shall have occurred and be
continuing, at any time at the Administrative Agent's election, the
Administrative Agent may apply all or any part of Proceeds held in any
Collateral Account in payment of the Secured Obligations in such order as the
Administrative Agent may elect.

         (b)  If an Event of Default shall occur and be continuing, the
Administrative Agent, on behalf of the Lenders, may exercise, in addition to
all other rights and remedies granted in this Agreement and in any other
instrument or agreement securing, evidencing or relating to the Secured
Obligations, all rights and remedies of a secured party under the Code.
Without limiting the generality of the foregoing, the Administrative Agent,
without demand of performance or other demand, presentment, protest,
advertisement or notice of any kind (except any notice required by law referred
to below) to or upon any Pledgor or any other Person (all and each of which
demands, defenses, advertisements and notices are hereby waived), may in such
circumstances forthwith collect, receive, appropriate and realize upon the
Collateral, or any part thereof, and/or may forthwith sell, assign, give option
or options to purchase or otherwise dispose of and deliver the Collateral or
any part thereof (or contract to do any of the foregoing), in one or more
parcels at public or private sale or sales, in the over-the-counter market, at
any exchange, broker's board or office of the Administrative Agent or any
Lender or elsewhere upon such terms and conditions as it may deem advisable and
at such prices as it may deem best, for cash or on credit or for future
delivery without assumption of any credit risk.  The Administrative Agent or
any Lender shall have the right upon any such public sale or sales, and, to the
extent permitted by law, upon any such private sale or sales, to purchase the
whole or any part of the Collateral so sold, free of any right or equity of
redemption in the relevant Pledgor, which right or equity is hereby waived or
released.  The Administrative Agent shall apply any Proceeds from time to time
held by it and the net proceeds of any such collection, recovery, receipt,
appropriation, realization or sale, after deducting all reasonable costs and
expenses of every kind incurred in respect thereof or incidental to the care or
safekeeping of any of the Collateral or in any way relating to the Collateral
or the rights of the Administrative Agent and the Lenders hereunder, including,
without limitation, reasonable attorneys' fees and disbursements of counsel to
the Administrative Agent, to the payment in whole or in part of the Secured
Obligations, in such order as the Administrative Agent may elect, and only
after such application and after the payment by the Administrative Agent of any
other amount required by any provision of law, including, without limitation,
Section 9-504(1)(c) of the Code, need the Administrative Agent account for the
surplus, if any, to the relevant Pledgor.  To the extent permitted by
applicable law, each Pledgor waives all claims, damages and demands it may
acquire against the Administrative Agent or any Lender arising out of the
exercise by them of any rights hereunder.  If any notice of a proposed sale or
other disposition of Collateral shall be required by law, such notice shall be
deemed reasonable and proper if given at least 10 days before such sale or
other disposition.

         (c)  Each Pledgor waives and agrees not to assert any rights or
privileges which it may acquire under Section 9-112 of the Code.  The Pledgors
shall remain liable for any deficiency if the proceeds of any sale or other
disposition of Collateral are insufficient to pay the Secured Obligations and
the fees and disbursements of any attorneys employed by the Administrative
Agent or any Lender to collect such deficiency.

         9.  Registration Rights; Private Sales.  (a)  If the Administrative
Agent shall determine to exercise its right to sell any or all of the Pledged
Stock pursuant to paragraph 8(b) hereof, and if in the opinion of the
Administrative Agent it is necessary or advisable to have the Pledged Stock, or
that portion thereof to be sold, registered under the provisions of the
Securities Act, each Pledgor will cause the Issuer thereof to (1) execute and
deliver, and cause the directors and officers of such Issuer to execute and
deliver, all such instruments and documents, and do or cause to be done all
such other acts as may be, in the opinion of the Administrative Agent,
necessary or advisable to register the Pledged Stock, or that portion thereof
to be sold, under the provisions of the Securities Act, (2) to use its best
efforts to cause the registration statement relating thereto to become
effective and to remain effective for a period of one year from the date of the
first public offering of the Pledged Stock, or that portion thereof to be sold,
and (3) to make all amendments thereto and/or to the related prospectus which,
in the opinion of the Administrative Agent, are necessary or advisable, all in
conformity with the requirements of the Securities Act and the rules and
regulations of the Securities and Exchange Commission applicable thereto.  Each
Pledgor agrees to cause such Issuer to comply with the provisions of the
securities or "Blue Sky" laws of any and all jurisdictions which the
Administrative Agent shall designate and to make available to its security
holders, as soon as practicable, an earnings statement (which need not be
audited) which will satisfy the provisions of Section 11(a) of the Securities
Act.

         (b)  Each Pledgor recognizes that the Administrative Agent may be
unable to effect a public sale of any or all the Pledged Stock, by reason of
certain prohibitions contained in the Securities Act and applicable state
securities laws or otherwise, and may be compelled to resort to one or more
private sales thereof to a restricted group of purchasers which will be obliged
to agree, among other things, to acquire such securities for their own account
for investment and not with a view to the distribution or resale thereof.  Each
Pledgor acknowledges and agrees that any such private sale may result in prices
and other terms less favorable than if such sale were a public sale and,
notwithstanding such circumstances, agrees that any such private sale shall be
deemed to have been made in a commercially reasonable manner.  The
Administrative Agent shall be under no obligation to delay a sale of any of the
Pledged Stock for the period of time necessary to permit the Issuer thereof to
register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if such Issuer would agree to do so.

         (c)  Each Pledgor further agrees to use its best efforts to do or
cause to be done all such other acts as may be necessary to make such sale or
sales of all or any portion of the Pledged Stock pursuant to this Section 9
valid and binding and in compliance with any and all other applicable
Requirements of Law.  Each Pledgor further agrees that a breach of any of the
covenants contained in this Section 9 will cause irreparable injury to the
Administrative Agent and the Lenders, that the Administrative Agent and the
Lenders have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this Section shall be
specifically enforceable against such Pledgor, and such Pledgor hereby waives
and agrees not to assert any defenses against an action for specific
performance of such covenants except for a defense that no Event of Default has
occurred under the Credit Agreement.

                                                                               8

         10.  Irrevocable Authorization and Instruction to Issuer.  Each
Pledgor hereby authorizes and instructs each Issuer to comply with any
instruction received by it from the Administrative Agent in writing that (a)
states that an Event of Default has occurred and (b) is otherwise in accordance
with the terms of this Agreement, without any other or further instructions
from such Pledgor, and each Pledgor agrees that each Issuer shall be fully
protected in so complying.

         11.  Administrative Agent's Appointment as Attorney-in-Fact.  (a)
Each Pledgor hereby irrevocably constitutes and appoints the Administrative
Agent and any officer or agent of the Administrative Agent, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of such Pledgor and in the name of
such Pledgor or in the Administrative Agent's own name, from time to time in
the Administrative Agent's discretion, for the purpose of carrying out the
terms of this Agreement, to take any and all appropriate action and to execute
any and all documents and instruments which may be necessary or desirable to
accomplish the purposes of this Agreement, including, without limitation, any
financing statements, endorsements, assignments or other instruments of
transfer.

         (b)  Each Pledgor hereby ratifies all that said attorneys shall
lawfully do or cause to be done pursuant to the power of attorney granted in
paragraph 11(a).  All powers, authorizations and agencies contained in this
Agreement are coupled with an interest and are irrevocable until this Agreement
is terminated and the security interests created hereby are released.

         12.  Duty of Administrative Agent.  The Administrative Agent's sole
duty with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the Code or otherwise,
shall be to deal with it in the same manner as the Administrative Agent deals
with similar securities and property for its own account, except that the
Administrative Agent shall have no obligation to invest funds held in any
Collateral Account and may hold the same as demand deposits.  Neither the
Administrative Agent, any Lender nor any of their respective directors,
officers, employees or agents shall be liable for failure to demand, collect or
realize upon any of the Collateral or for any delay in doing so or shall be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of any Pledgor or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof.

         13.  Execution of Financing Statements.  Pursuant to Section 9-402 of
the Code, each Pledgor authorizes the Administrative Agent to file financing
statements with respect to the Collateral without the signature of such Pledgor
in such form and in such filing offices as the Administrative Agent reasonably
determines appropriate to perfect the security interests of the Administrative
Agent under this Agreement.  A carbon, photographic or other reproduction of
this Agreement shall be sufficient as a financing statement for filing in any
jurisdiction.

         14.  Authority of Administrative Agent.  Each Pledgor acknowledges
that the rights and responsibilities of the Administrative Agent under this
Agreement with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, voting
right, request, judgment or other right or remedy

                                                                               9
provided for herein or resulting or arising out of this Agreement shall, as
between the Administrative Agent and the Lenders, be governed by the Credit
Agreement and by such other agreements with respect thereto as may exist from
time to time among them, but, as between the Administrative Agent and the
Pledgors, the Administrative Agent shall be conclusively presumed to be acting
as agent for the Lenders with full and valid authority so to act or refrain
from acting, and neither the Pledgors nor any Issuer shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

         15.  Notices.  All notices, requests and demands to or upon the
Administrative Agent or the Pledgors to be effective shall be effected in the
manner provided for in subsection 11.2 of the Credit Agreement, addressed as
follows:

         (1)  if to the Administrative Agent, at its address or transmission
number for notices provided in subsection 11.2 of the Credit Agreement; and

         (2)  if to a Pledgor, at its address or transmission number for
notices set forth on Schedule 2 hereto.  The Administrative Agent and the
Pledgors may change their addresses and transmission numbers for notices by
notice in the manner provided in this subsection 11.2 of the Credit Agreement.

         16.  Severability.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         17.   Amendments in Writing; No Waiver; Cumulative Remedies.  (a)
None of the terms or provisions of this Agreement may be waived, amended,
supplemented or otherwise modified in accordance with subsection 11.01 of the
Credit Agreement.

         (b)  Neither the Administrative Agent nor any Lender shall by any act
(except by a written instrument pursuant to paragraph 17(a) hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any Default or Event of Default or in any
breach of any of the terms and conditions hereof.  No failure to exercise, nor
any delay in exercising, on the part of the Administrative Agent or any Lender,
any right, power or privilege hereunder shall operate as a waiver thereof.  No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege.  A waiver by the Administrative Agent or any Lender
of any right or remedy hereunder on any one occasion shall not be construed as
a bar to any right or remedy which the Administrative Agent or such Lender
would otherwise have on any future occasion.

         (c)  The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

                                   GUARANTEE

         GUARANTEE, dated as of November 5, 1997 (this "Guarantee"), made by
each of the corporations that are signatories hereto (the "Guarantors"), in
favor of THE CHASE MANHATTAN BANK, as Administrative Agent (in such capacity,
the "Administrative Agent") for the lenders (the "Lenders") from time to time
parties to the Credit Agreement, dated as of November 5, 1997 (as amended,
supplemented or otherwise modified from time to time, the "Credit Agreement"),
among THE MERIDIAN RESOURCE CORPORATION (the "Borrower"), the Lenders and the
Administrative Agent.


                              W I T N E S S E T H:


         WHEREAS, pursuant to the Credit Agreement, the Lenders have severally
agreed to make Loans to the Borrower upon the terms and subject to the
conditions set forth therein, to be evidenced by the Notes issued by the
Borrower under the Credit Agreement;

         WHEREAS, each of the Guarantors is a Subsidiary (as defined in the
Credit Agreement) of the Borrower;

         WHEREAS, the proceeds of the Extensions of Credit will be used in part
to enable the Borrower to make valuable transfers (as determined as provided
herein) to each Guarantor in connection with the operation of their respective
businesses;

         WHEREAS, the Borrower and the Guarantors are engaged in related
businesses, and each Guarantor will derive substantial direct and indirect
benefit from the making of the Extensions of Credit; and

         WHEREAS, it is a condition precedent to the obligation of the Lenders
to make their respective Extensions of Credit to the Borrower under the Credit
Agreement that the Guarantors shall have executed and delivered this Guarantee
to the Administrative Agent for the ratable benefit of the Lenders.

         NOW, THEREFORE, in consideration of the premises and to induce the
Administrative Agent and the Lenders to enter into the Credit Agreement and to
induce the Lenders to make their respective loans to the Borrower under the
Credit Agreement, the Guarantors hereby agree with the Administrative Agent,
for the ratable benefit of the Lenders, as follows:

         1. Defined Terms.  (a)  Unless otherwise defined herein, terms defined

<PAGE>   2
                                                                               2
obligations and liabilities of the Borrower (including, without limitation,
interest accruing at the then applicable rate provided in the Credit Agreement
after the maturity of the Loans and interest accruing at the then applicable
rate provided in the Credit Agreement after the filing of any petition in
bankruptcy, or the commencement of any insolvency, reorganization or like
proceeding, relating to the Borrower, whether or not a claim for post-filing or
post-petition interest is allowed in such proceeding) to the Administrative
Agent or any of the Lenders (or, in the case of any Hedging Agreement referred
to below, any Affiliate of any Lender), whether direct or indirect, absolute or
contingent, due or to become due, or now existing or hereafter incurred, which
may arise under, out of, or in connection with, the Credit Agreement, any
Notes, any Letter of Credit, the other Loan Documents or any Hedging Agreement
entered into by the Borrower with any Lender (or any Affiliate of any Lender)
or any other document made, delivered or given in connection therewith, in each
case whether on account of principal, interest, reimbursement obligations,
fees, indemnities, costs, expenses or otherwise (including, without limitation,
all fees and disbursements of counsel to the Administrative Agent or to the
Lenders that are required to be paid by the Borrower or the Guarantors pursuant
to the terms of the Credit Agreement or this Agreement or any other Loan
Document).

         (c)  The words "hereof," "herein" and "hereunder" and words of similar
import when used in this Guarantee shall refer to this Guarantee as a whole and
not to any particular provision of this Guarantee, and section and paragraph
references are to this Guarantee unless otherwise specified.

         (d)  The meanings given to terms defined herein shall be equally
applicable to both the singular and plural forms of such terms.

         2.  Guarantee.  (a)  Subject to the provisions of paragraph 2(b), each
of the Guarantors hereby, jointly and severally, unconditionally and
irrevocably, guarantees to the Administrative Agent, for the ratable benefit of
the Lenders and their respective successors, indorsees, transferees and
assigns, the prompt and complete payment and performance by the Borrower when
due (whether at the stated maturity, by acceleration or otherwise) of the
Obligations.

         (b)  Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of each Guarantor hereunder and under
the other Loan Documents shall in no event exceed the amount which can be
guaranteed by such Guarantor under applicable federal and state laws relating
to the insolvency of debtors (after giving affect to the right of contribution
established in Section 3).

         (c)  Each Guarantor further agrees to pay any and all expenses
(including, without limitation, all fees and disbursements of counsel) which
may be paid or incurred by the Administrative Agent or any Lender in enforcing,
or obtaining advice of counsel in respect of, any rights with respect to, or
collecting, any or all of the Obligations and/or enforcing any rights with
respect to, or collecting against, such Guarantor under this Guarantee.  This
Guarantee shall remain in full force and effect until the Obligations are paid
in full, no Letter

                                                                               3
of Credit shall be outstanding, and the Commitments are terminated,
notwithstanding that from time to time prior thereto the Borrower may be free
from any Obligations.

         (d)  Each Guarantor agrees that the Obligations may at any time and
from time to time exceed the amount of the liability of such Guarantor
hereunder without impairing this Guarantee or affecting the rights and remedies
of the Administrative Agent or any Lender hereunder.

         (e)  No payment or payments made by the Borrower, any of the
Guarantors, any other guarantor or any other Person or received or collected by
the Administrative Agent or any Lender from the Borrower, any of the
Guarantors, any other guarantor or any other Person by virtue of any action or
proceeding or any set-off or appropriation or application at any time or from
time to time in reduction of or in payment of the Obligations shall be deemed
to modify, reduce, release or otherwise affect the liability of any Guarantor
hereunder which shall, notwithstanding any such payment or payments other than
payments made by such Guarantor in respect of the Obligations or payments
received or collected from such Guarantor in respect of the Obligations, remain
liable for the Obligations up to the maximum liability of such Guarantor
hereunder until the Obligations are paid in full, no Letter of Credit shall be
outstanding, and the Commitments are terminated.

         (f)  Each Guarantor agrees that whenever, at any time, or from time to
time, it shall make any payment to the Administrative Agent or any Lender on
account of its liability hereunder, it will notify the Administrative Agent in
writing that such payment is made under this Guarantee for such purpose.

         3.  Right of Contribution.  Each Guarantor hereby agrees that to the
extent that a Guarantor shall have paid more than its proportionate share of
any payment made hereunder, such Guarantor shall be entitled to seek and
receive contribution from and against any other Guarantor hereunder who has not
paid its proportionate share of such payment.  Each Guarantor's right of
contribution shall be subject to the terms and conditions of Section 5 hereof.
The provisions of this Section shall in no respect limit the obligations and
liabilities of any Guarantor to the Administrative Agent and the Lenders, and
each Guarantor shall remain liable to the Administrative Agent and the Lenders
for the full amount guaranteed by such Guarantor hereunder.

         4.  Right of Set-off.  Each Guarantor hereby irrevocably authorizes
each Lender at any time and from time to time, so long as an Event of Default
has occurred and is continuing, without notice to such Guarantor or any other
Guarantor, any such notice being expressly waived by each Guarantor, to set-off
and appropriate and apply any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender to or for the credit or the account of such Guarantor, or
any part thereof in such amounts as such Lender may elect, against and on
account of the obligations and liabilities of such Guarantor to such Lender
hereunder and claims of every nature and description of such Lender against
such Guarantor, in any currency, whether arising hereunder, under the Credit
Agreement, any Note,





<PAGE>   4



                                                                               4
any Letter of Credit, any other Loan Document or otherwise, as such Lender may
elect, whether or not the Administrative Agent or any Lender has made any
demand for payment and although such obligations, liabilities and claims may be
contingent or unmatured.  The Administrative Agent and each Lender shall notify
such Guarantor promptly of any such set- off and the application made by the
Administrative Agent or such Lender, provided that the failure to give such
notice shall not affect the validity of such set-off and application.  The
rights of the Administrative Agent and each Lender under this Section are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) which the Administrative Agent or such Lender may have.

         5.  No Subrogation.  Notwithstanding any payment or payments made by
any of the Guarantors hereunder or any set-off or application of funds of any
of the Guarantors by the Administrative Agent or any Lender, no Guarantor shall
be entitled to be subrogated to any of the rights of the Administrative Agent
or any Lender against the Borrower or any other Guarantor or any collateral
security or guarantee or right of offset held by any Lender for the payment of
the Obligations, nor shall any Guarantor seek or be entitled to seek any
contribution or reimbursement from the Borrower or any other Guarantor in
respect of payments made by such Guarantor hereunder, until all amounts owing
to the Administrative Agent and the Lenders by the Borrower on account of the
Obligations are paid in full, no Letter of Credit shall be outstanding and the
Commitments are terminated.  If any amount shall be paid to any Guarantor on
account of such subrogation rights at any time when all of the Obligations
shall not have been paid in full, such amount shall be held by such Guarantor
in trust for the Administrative Agent and the Lenders, segregated from other
funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor,
be turned over to the Administrative Agent in the exact form received by such
Guarantor (duly indorsed by such Guarantor to the Administrative Agent, if
required), to be applied against the Obligations, whether matured or unmatured,
in such order as the Administrative Agent may determine.

         6.  Amendments, etc. with respect to the Obligations; Waiver of
Rights.  Each Guarantor shall remain obligated hereunder notwithstanding that,
without any reservation of rights against any Guarantor and without notice to
or further assent by any Guarantor, any demand for payment of any of the
Obligations made by the Administrative Agent or any Lender may be rescinded by
such Person and any of the Obligations continued, and the Obligations, or the
liability of any other Person upon or for any part thereof, or any collateral
security or guarantee therefor or right of offset with respect thereto, may,
from time to time, in whole or in part, be renewed, extended, amended,
modified, accelerated, compromised, waived, surrendered or released by the
Administrative Agent or any Lender, and the Credit Agreement, any Notes and the
other Loan Documents and any other documents executed and delivered in
connection therewith may be amended, modified, supplemented or terminated, in
whole or in part, as the Administrative Agent (or the Required Lenders, as the
case may be) may deem advisable from time to time, and any collateral security,
guarantee or right of offset at any time held by the Administrative Agent or
any Lender for the payment of the Obligations may be sold, exchanged, waived,
surrendered or released.  Neither the Administrative Agent nor any Lender shall
have any obligation to protect, secure, perfect or insure any Lien at any time
held by it as security for the Obligations or for this Guarantee or any
property subject thereto.  When making any demand hereunder against any of the

                                                                               5
Guarantors, the Administrative Agent or any Lender may, but shall be under no
obligation to, make a similar demand on the Borrower or any other Guarantor or
guarantor, and any failure by the Administrative Agent or any Lender to make
any such demand or to collect any payments from the Borrower or any such other
Guarantor or guarantor or any release of the Borrower or such other Guarantor
or guarantor shall not relieve any of the Guarantors in respect of which a
demand or collection is not made or any of the Guarantors not so released of
their several obligations or liabilities hereunder, and shall not impair or
affect the rights and remedies, express or implied, or as a matter of law, of
the Administrative Agent or any Lender against any of the Guarantors.  For the
purposes hereof "demand" shall include the commencement and continuance of any
legal proceedings.

         7.  Guarantee Absolute and Unconditional.  Each Guarantor waives any
and all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the Administrative Agent or
any Lender upon this Guarantee or acceptance of this Guarantee, the
Obligations, and any of them, shall conclusively be deemed to have been
created, contracted or incurred, or renewed, extended, amended or waived, in
reliance upon this Guarantee; and all dealings between the Borrower and any of
the Guarantors, on the one hand, and the Administrative Agent and the Lenders,
on the other hand, likewise shall be conclusively presumed to have been had or
consummated in reliance upon this Guarantee.  Each Guarantor waives diligence,
presentment, protest, demand for payment and notice of default or nonpayment to
or upon the Borrower or any of the Guarantors with respect to the Obligations.
Each Guarantor understands and agrees that this Guarantee shall be construed as
a continuing, absolute and unconditional guarantee of payment without regard to
(a) the validity, regularity or enforceability of the Credit Agreement, any
Note or any other Loan Document, any of the Obligations or any other collateral
security therefor or guarantee or right of offset with respect thereto at any
time or from time to time held by the Administrative Agent or any Lender (b)
any defense, set-off or counterclaim (other than a defense of payment or
performance) which may at any time be available to or be asserted by the
Borrower against the Administrative Agent or any Lender, or (c) any other
circumstance whatsoever (with or without notice to or knowledge of the Borrower
or such Guarantor) which constitutes, or might be construed to constitute, an
equitable or legal discharge of the Borrower for the Obligations, or of such
Guarantor under this Guarantee, in bankruptcy or in any other instance.  When
pursuing its rights and remedies hereunder against any Guarantor, the
Administrative Agent and any Lender may, but shall be under no obligation to,
pursue such rights and remedies as it may have against the Borrower or any
other Person or against any collateral security or guarantee for the
Obligations or any right of offset with respect thereto, and any failure by the
Administrative Agent or any Lender to pursue such other rights or remedies or
to collect any payments from the Borrower or any such other Person or to
realize upon any such collateral security or guarantee or to exercise any such
right of offset, or any release of the Borrower or any such other Person or any
such collateral security, guarantee or right of offset, shall not relieve such
Guarantor of any liability hereunder, and shall not impair or affect the rights
and remedies, whether express, implied or available as a matter of law, of the
Administrative Agent and the Lenders against such Guarantor.  This Guarantee
shall remain in full force and effect and be binding in accordance with and to
the extent of its terms upon each Guarantor and the successors and assigns
thereof, and shall inure to the benefit of the Administrative Agent and the
Lenders, and their respective

successors, endorsees, transferees and assigns, until all the Obligations and
the obligations of each Guarantor under this Guarantee shall have been
satisfied by payment in full, no Letter of Credit shall be outstanding, and the
Commitments shall be terminated, notwithstanding that from time to time during
the term of the Credit Agreement the Borrower may be free from any Obligations.

         8.  Reinstatement.  This Guarantee shall continue to be effective, or
be reinstated, as the case may be, if at any time payment, or any part thereof,
of any of the Obligations is rescinded or must otherwise be restored or
returned by the Administrative Agent or any Lender upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Borrower or any
Guarantor, or upon or as a result of the appointment of a receiver, intervenor
or conservator of, or trustee or similar officer for, the Borrower or any
Guarantor or any substantial part of its property, or otherwise, all as though
such payments had not been made.

         9.  Payments.  Each Guarantor hereby guarantees that payments
hereunder will be paid to the Administrative Agent without set-off or
counterclaim in Dollars at the office of the Administrative Agent located at
270 Park Avenue, New York, New York 10017.

         10.  Representations and Warranties.  Each Guarantor hereby represents
and warrants to the Administrative Agent and each Lender that, the
representations and warranties set forth in Section 5 of the Credit Agreement
as they relate to such Guarantor or to the Loan Documents to which such
Guarantor is a party, each of which is hereby incorporated herein by reference,
are true and correct, and the Administrative Agent and each Lender shall be
entitled to rely on each of them as if they were fully set forth herein;
provided that each reference in each such representation and warranty to the
Borrower's knowledge shall, for the purposes of this Section 10 be deemed to be
a reference to such Guarantor's knowledge.

                 Each Guarantor agrees that the foregoing representations and
warranties shall be deemed to have been made by such Guarantor on the date of
each Extension of Credit under the Credit Agreement on and as of such date of
Extension of Credit as though made hereunder on and as of such date.

         11.  Covenants.  Each Guarantor covenants and agrees with the
Administrative Agent and each Lender that, from and after the date of this
Guarantee until the Obligations shall have been paid in full, no Letter of
Credit shall be outstanding and the Commitments shall have terminated, such
Guarantor shall take, or shall refrain from taking, as the case may be, each
action that is necessary to be taken or not taken, as the case may be, so that
no Default or Event of Default is caused by the failure to take such action or
to refrain from taking such action by such Guarantor or any of its
Subsidiaries.

         12.  Authority of Administrative Agent.  Each Guarantor acknowledges
that the rights and responsibilities of the Administrative Agent under this
Guarantee with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, right,
request, judgment or other right or remedy provided for herein or resulting or
arising out of this Guarantee shall, as between the Administrative Agent and
the Lenders, be governed by the Credit Agreement and by such

other agreements with respect thereto as may exist from time to time among
them, but, as between the Administrative Agent and such Guarantor, the
Administrative Agent shall be conclusively presumed to be acting as agent for
the Lenders with full and valid authority so to act or refrain from acting, and
no Guarantor shall be under any obligation, or entitlement, to make any inquiry
respecting such authority.

         13.  Notices.  All notices, requests and demands to or upon the
Administrative Agent, any Lender or any Guarantor shall be effected in the
manner provided for in subsection 11.2 of the Credit Agreement, addressed as
follows:

         (a)  if to the Administrative Agent or any Lender, at its address or
transmission number for notices provided in subsection 11.2 of the Credit
Agreement; and

         (b)  if to any Guarantor, at its address or transmission number for
notices set forth under its signature below.

         The Administrative Agent, each Lender and each Guarantor may change
its address and transmission numbers for notices by notice in the manner
provided in this Section.

         14.  Counterparts.  This Guarantee may be executed by one or more of
the Guarantors on any number of separate counterparts, and all of said
counterparts taken together shall be deemed to constitute one and the same
instrument.

         15.  Severability.  Any provision of this Guarantee which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         16.   Integration.  This Guarantee represents the agreement of each
Guarantor with respect to the subject matter hereof and there are no promises
or representations by the Administrative Agent or any Lender relative to the
subject matter hereof not reflected herein.

         17.   Amendments in Writing; No Waiver; Cumulative Remedies.  (a)
None of the terms or provisions of this Guarantee may be waived, amended,
supplemented or otherwise modified except in accordance with subsection 11.1 of
the Credit Agreement.

         (b)  Neither the Administrative Agent nor any Lender shall by any act
(except by a written instrument pursuant to paragraph 17(a) hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any Default or Event of Default or in any
breach of any of the terms and conditions hereof.  No failure to exercise, nor
any delay in exercising, on the part of the Administrative Agent or any Lender,
any right, power or privilege hereunder shall operate as a waiver thereof.  No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege.  A waiver by the Administrative Agent or any Lender
of any right or remedy hereunder on any one

occasion shall not be construed as a bar to any right or remedy which the

exercised singly or concurrently and are not exclusive of any other rights or

agrees that service of process in any such action or proceeding may be effected
by mailing a copy thereof by registered or certified mail (or any substantially

Administrative Agent shall have been notified pursuant thereto; (4)  agrees
that nothing herein shall affect the right to effect service of process in any

any right it may have to claim or recover in any legal action or proceeding
referred to in this subsection any special, exemplary, punitive or
consequential damages.

         19.  WAIVERS OF JURY TRIAL.  THE GUARANTORS HEREBY KNOWINGLY AND

                    [Fulbright & Jaworski L.L.P. Letterhead]

November 11,1997

The Meridian Resource Corporation
15995 N. Barker's Landing, Suite 300
Houston, Texas 77079

Ladies and Gentlemen:

     We have acted as counsel to The Meridian Resource Corporation, a Texas
corporation (the "Company"), in connection with the registration under the
Securities Act of 1933 (the "Act") of an aggregate of 2,742,899 shares (the
"Shares") of the Company's common stock, $.01 par value (the "Common Stock") of
which (i) 949,659 shares of Common Stock are to offered upon the terms and
subject to the conditions set forth in the Texas Meridian Resources 
Corporation 1995 Long-Term Incentive Plan (the "1995 Plan"), (ii) 949,659 
shares of Common Stock are to offered upon the terms and subject to the 
conditions set forth in the Texas Meridian Resources Corporation 1997 Long-
Term Incentive Plan (the "1997 Plan"), (iii) 731,341 shares of Common Stock are
to offered upon the terms and subject to the conditions set forth in the Cairn
Energy USA, Inc. 1993 Stock Option Plan, as amended (the "1993 Plan"), and 
(iv) 112,240 shares of Common Stock are to offered upon the terms and subject 
to the conditions set forth in the Cairn Energy USA, Inc. 1993 Directors Stock
Option Plan, as amended (the "Directors Plan") and together with the 1995 Plan,
1997 Plan and the 1993 Plan, the "Plans"). 

     We have examined or considered originals or copies, certified or 
otherwise identified to our satisfaction, of the Second Amended and Restated
Articles of Incorporation of the Company, the By-laws of the Company, as
amended, the Plans, records of relevant corporate proceedings with respect to
the offering of the Shares and such other documents, instruments and corporate
records as we have deemed necessary or appropriate for the expression of the
opinions contained herein.  We have also reviewed the Company's Registration
Statement on Form S-8 (the "Registration Statement") to be filed with the
Securities and Exchange Commission with respect to the Shares.

     We have assumed the authenticity and completeness of all records,
certificates and other instruments submitted to us as originals, the
conformity to original documents of all records, certificates and other
instruments submitted to us as copies, the authenticity and completeness of the
originals of those records, certificates and other instruments submitted to us
as copies and the correctness of all statements of fact contained in all
records, certificates and other instruments that we have examined.

     Based on the foregoing and having regard for such legal consideration as
we have deemed relevant, we are of the opinion that the Shares have been duly
and validly authorized for issuance and, when issued in accordance with the
terms of the applicable Plan, will be duly and validly issued, fully paid and
nonassessable.

     The foregoing opinion is limited to the federal laws of the United States
of America and the Texas Business Corporation Act, and we are expressing no
opinion as to the effect of the laws of any other jurisdiction.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                        Sincerely,

                                        /s/Fulbright & Jaworski L.L.P.

                                        Fulbright & Jaworski L.L.P.
