            FOURTH AMENDMENT TO SECOND LIEN SECURED CREDIT AGREEMENT

         THIS FOURTH AMENDMENT TO SECOND LIEN SECURED CREDIT AGREEMENT (this
"Amendment") is entered into as of December 29, 2004, between PetroQuest Energy,
LLC, a Louisiana limited liability company ("Borrower"), and Macquarie Bank
Limited, an Australian corporation ("Lender"). Capitalized terms used but not
defined in this Amendment have the meaning given them in the Credit Agreement
(defined below).

                                   Background

     A.  Borrower and Lender have previously entered into a Credit Agreement
         dated November 6, 2003 (as amended, the "Credit Agreement") for the
         purpose of making available to Borrower a senior second lien secured
         term loan on a non-revolving basis.

     B.  Borrower has requested that Lender modify the Availability Termination
         Date for the facility.

     C.  Lender is willing to amend the Credit Agreement pursuant to the terms
         and conditions of this Amendment.

                                   Agreements

         In consideration of the mutual covenants of Borrower and Lender set
forth in this Amendment, receipt of the acknowledgement of this amendment by
JPMorgan Chase Bank, N.A. (successor by merger to Bank One, N.A.) and other good
and valuable consideration, the receipt and sufficiency of which are
acknowledged by each of the parties, Borrower and Lender agree as follows:

     1.  Amendments to Credit Agreement.
         -------------------------------

               Modifications to Existing Definitions. The definition of
               Availability Termination Date is deleted in its entirety and
               replaced with the following:

                  "Availability Termination Date" means December 31, 2005.

     2.  Reaffirmation of Representations and Warranties. To induce Lender to
         enter into this Amendment, Borrower hereby reaffirms, as of the date
         hereof, its representations and warranties contained in Article IV of
         the Credit Agreement and in all other documents executed pursuant
         thereto, and additionally represents and warrants as follows:

                      a) The execution and delivery of this Amendment and the
                  performance by Borrower of its obligations under this
                  Amendment are within Borrower's power, have been duly
                  authorized by all necessary partnership action, have received
                  all necessary government approval (if any shall be required),
                  and do not and will not contravene or conflict with any
                  provision of law or of

                                       1
<PAGE>

                  the certificate of limited partnership or the partnership
                  agreement of Borrower or of any agreement binding upon
                  Borrower.

                      b) This Amendment represents the legal, valid and binding
                  obligations of Borrower enforceable against Borrower in
                  accordance with its terms subject as to enforcement only to
                  bankruptcy, insolvency, reorganization, moratorium or other
                  similar laws affecting the enforcement of creditors' rights
                  generally.

     3.  Ratification of Liens and Security Interests. Borrower hereby
         acknowledges and ratifies the existence and priority of the Liens
         granted by Borrower in favor of Lender in and to the Collateral and
         represents, warrants and covenants that such liens and security
         interests are valid, existing and in full force and effect.

     4.  Miscellaneous. This Amendment supersedes all prior agreements (written
         or oral) between Borrower and Lender with regard to the subject matters
         hereof. This Amendment is a Loan Document. Except as affected by this
         Amendment, the Loan Documents are unchanged and continue in full force
         and effect. However, in the event of any inconsistency between the
         terms of the Credit Agreement as amended by this Agreement and any
         other Loan Document, the terms of the Credit Agreement will control and
         the other document will be deemed to be amended to conform to the terms
         of the Credit Agreement. All references to the Credit Agreement will
         refer to the Credit Agreement as amended by this Amendment. Borrower
         agrees that all Loan Documents to which it is a party (whether as an
         original signatory or by assumption of the Obligations) remain in full
         force and effect and continue to evidence its legal, valid and binding
         obligations enforceable in accordance with their terms (as the same are
         affected by this Amendment or are amended in connection with this
         Amendment). Borrower releases Lender from any liability for actions or
         failures to act in connection with the Loan Documents prior to the date
         of this Amendment. Any course of dealing among Borrower or Lender or
         any other Person will not be deemed to have altered or amended the
         Credit Agreement or affected either Borrower's of Lender's right to
         enforce the Credit Agreement as written. This Amendment will be binding
         upon and inure to the benefit of each of the undersigned and their
         respective successors and permitted assigns.

     5.  No waiver of Default

         Neither this Amendment nor any course of dealing between Borrower and
         Lender prior to or after the date of this Amendment constitutes a
         waiver of, or a consent to, any present or future violation of or
         default under, any provision of the Loan Documents, or a waiver of
         Lender's right to insist upon future compliance with each term,
         covenant, condition and provision of the Loan Documents, and the Loan
         Documents shall continue to be binding upon, and inure to the benefit
         of, Borrower and Lender and their respective successors and assigns.

     6.  Form. Each agreement, document, instrument or other writing to be
         furnished Lender under any provision of this instrument must be in form
         and substance satisfactory to Lender and its counsel.

                                       2

     7.  Multiple Counterparts. This Amendment may be executed in more than one
         counterpart, each of which shall be deemed an original, and all of
         which constitute, collectively, one instrument; but, in making proof of
         this instrument, it shall not be necessary to produce or account for
         more than one such counterpart. It shall not be necessary for Borrower
         and Lender to execute the same counterpart hereof so long as Borrower
         and Lender execute a counterpart hereof.

     8.  Governing Law. This Amendment and all transactions provided for in this
         Amendment will be governed by, interpreted and construed under and
         enforced pursuant to the laws of the State of Texas, without regard to
         its conflicts of laws provisions.

     9.  Final Agreement. THE LOAN DOCUMENTS, AS AMENDED BY OR IN CONNECTION
         WITH THIS AMENDMENT, REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES
         AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
         SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO ORAL AGREEMENTS
         BETWEEN THE PARTIES.

"Borrower"), the several banks, financial institutions and other entities from
time to time parties to this Agreement (collectively, the "Lenders"), Fortis
Capital Corp. ("Fortis"), as administrative agent for the Lenders (in such
capacity, the "Administrative Agent"), and as sole lead arranger (in such
capacity, the "Sole Lead Arranger") and bookrunner (in such capacity, a
"Bookrunner"), COMERICA BANK, as syndication agent (in such capacity, the
"Syndication Agent"), and UNION BANK OF CALIFORNIA, N. A., as documentation
agent (in such capacity, the "Documentation Agent).

                                   WITNESSETH:

      WHEREAS, the Borrower is, as of the date hereof, party to a Credit
Agreement dated as of August 13, 2002 (as heretofore amended or otherwise
modified, the "Existing Credit Facility"), with the lenders from time to time
parties thereto, and Societe Generale, as administrative agent, and pursuant
hereto the Borrower and the Administrative Agent desire to refinance the
indebtedness and obligations arising under the Existing Credit Facility, and the
indebtedness and liens arising under the Existing Credit Facility have been
assigned to the Administrative Agent and the Lenders, so that all indebtedness
and obligations arising hereunder shall be secured by such liens and security
interests as were created pursuant to the Existing Credit Facility and such
other liens as provided for herein, and the terms of Borrower's financing shall
hereafter be exclusively as set forth herein;

      NOW, THEREFORE, in consideration of the premises and the mutual agreements
hereinafter set forth, the parties 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

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 Fortis 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 Fortis in connection
with extensions of credit to debtors); and "Federal Funds Effective Rate" shall
mean, for any day, the weighted average of the rates on overnight federal funds
transactions with members of the Federal Reserve System arranged by federal
funds brokers, as published on the next succeeding Business Day by the Federal
Reserve Bank of New York, or, if such rate is not so published for any day which
is a Business Day, the average of the quotations for the day of such
transactions received by the Administrative Agent from three federal funds
brokers of recognized standing selected by it. Any change in the ABR due to a
change in the Prime Rate or the Federal Funds Effective Rate

      2.1. Revolving Credit Commitments. (a) Subject to the terms and conditions
hereof, including, without limitation, the satisfaction of the conditions
precedent set forth in Section 6 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

Amended and Restated Credit Agreement

<PAGE>
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, or the amount of outstanding
Eurodollar Loans after any repayment of any Eurodollar Loans, 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 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,
including, without limitation, the satisfaction of the conditions precedent set
forth in Section 6 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 (the "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 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

Amended and Restated Credit Agreement
                                       22
<PAGE>
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 (A) for Financial Letters of Credit, the Applicable Margin in effect from
time to time for Eurodollar Loans of the daily aggregate amount available to be
drawn under such Financial Letter of Credit during such period or (B) for
Performance Letters of Credit, the Applicable Margin in effect from time to time
for Eurodollar Loans of the daily aggregate amount available to be drawn under
such Performance 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, 2004, 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.

            (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 issued after the Closing Date, 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

Amended and Restated Credit Agreement
                                       23
<PAGE>
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 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

Amended and Restated Credit Agreement
                                       24
<PAGE>
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

<PAGE>
            (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

            (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 or the Eurocurrency Reserve Requirements
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 Required Lenders have
determined that such a conversion is not

Amended and Restated Credit Agreement
                                       26
<PAGE>
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 six (6) 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 of $1,000,000 in excess
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

Amended and Restated Credit Agreement
                                       27
<PAGE>
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 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, then, 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 prepayments 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

Amended and Restated Credit Agreement
                                       28
<PAGE>
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, 2004) and on the 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.

      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,

Amended and Restated Credit Agreement
                                       29
<PAGE>
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
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) Borrowing Base. (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. The Borrowing Base will be based upon
the value of 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 Required Lenders or all of the
Lenders, as the case may be. 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 15 and September 15 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
no earlier than the immediately preceding December 31 (in the case of Reserve
Reports due on March 15) and June 30 (in the case of Reserve Reports due on
September 15 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

Amended and Restated Credit Agreement
                                       30
<PAGE>
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 reasonable 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 material additions to or material 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) Redetermination of the Borrowing Base. The Borrowing Base shall
be redetermined (i) after receipt by the Administrative Agent of each scheduled
Reserve Report, (ii) upon the delivery of a Lender Redetermination Notice to the
Borrower and (iii) upon the delivery 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 prepared by engineers employed by the
Borrower and certified by a Responsible Officer of the Borrower as of the most
recent practicable date and, if requested by the Required Lenders, within 30
days after the delivery of a Borrower Redetermination Notice or a Lender
Redetermination Notice, a Reserve Report prepared by the Borrower and audited by
T.J. Smith & Company Inc. or another independent engineering firm selected by
the Borrower and reasonably acceptable to the Administrative Agent. If the
Borrower fails to deliver a Reserve Report within the time period provided for
in either the preceding sentence or in subsection 4.9(b) above, then the
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. 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
(i) with respect to regularly scheduled Reserve Reports, (A) on or before April
15 (in the case of Reserve Reports due on March 15) and (B) on or before October
15 (in the case of Reserve Reports due on September 15), and (ii) with respect
to a Lender Redetermination Notice or a Borrower Redetermination Notice, as
promptly as practicable following delivery to the Administrative Agent of all
information (including Reserve Reports) requested from the Borrower, or if no
such information is delivered by Borrower following such request, then at such
time as the Administrative Agent determines is practicable. Within 15 Business
Days after receipt from the Administrative Agent of the amount of its
redetermination of the Borrowing Base, each Lender shall notify the
Administrative Agent in writing 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. The Borrowing Base may be decreased from the then effective
Borrowing Base with the consent of Required Lenders but may only be increased
from the then effective Borrowing Base with the consent of all of the Lenders.
If Required Lenders or all of the Lenders, as the case may be, agree with that
redetermination, then the Administrative Agent promptly shall notify the
Borrower of the Borrowing Base as so redetermined, whereupon, with respect to
redeterminations made in connection with regularly scheduled Reserve Reports,
that redetermined value shall become effective (and shall remain effective until
the Borrowing Base is again redetermined as provided in this subsection (c)) on
April 30 (in the case of Reserve Reports due on March 15) and October 31 (in the
case of Reserve Reports due on September 15). If Required Lenders or all of the
Lenders, as the case may be, have not approved in writing or are

Amended and Restated Credit Agreement
                                       31
<PAGE>
not deemed to have approved the Borrowing Base within the 15 Business 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 Required Lenders or all
of the Lenders, as the case may be, 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
redetermination of the Borrowing Base be administratively completed by the
Lenders within 45 days after the furnishing of each Reserve Report, subject to
the provisions of this paragraph (c) but effective (notwithstanding the date
that redetermination is completed) only on the applicable date provided in
Section 4.9(d)(ii) hereof.

            (d) Criteria.

                  (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 Required Lenders or all of the Lenders, as the case may
            be, 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 oil and gas lending criteria as they
            customarily used at the time of determination in assigning
            collateral value to oil and gas properties for similarly situated
            customers of the Administrative Agent and the Lenders.

                  (ii) All redeterminations (other than those arising from a
            Borrower Redetermination Notice or a Lender Redetermination Notice)
            of the Borrowing Base referred to in this subsection 4.9 shall
            become effective on April 30 (in the case of Reserve Reports due on
            March 15) and October 31 (in the case of Reserve Reports due on
            September 15). Borrowing Base redeterminations arising from a
            Borrower Redetermination Notice or a Lender Redetermination Notice
            shall become effective upon written notice by the Administrative
            Agent to the Borrower and the Lenders of the redetermined Borrowing
            Base as redetermined in accordance with the terms hereof.

                  (iii) Upon the issuance of Subordinated Indebtedness, 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.

            (e) Title. 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.

<PAGE>
            (f) Mandatory Reductions. The Borrowing Base shall automatically be
reduced by the loan value assigned to each Oil and Gas Property in the Borrowing
Base (as determined by the Administrative Agent in its sole discretion) that is
Disposed by the Borrower in accordance with Section 8.6(d).

            (g) Initial Borrowing Base. The initial Borrowing Base hereunder
shall be $130,000,000.00

      4.10. Borrowing Base Compliance. If at any time the Aggregate Revolving
Credit Exposure of the Lenders exceeds the Borrowing Base then in effect (any
such excess, the "Borrowing Base Deficiency") (including as a result of a
redetermination in connection with the incurrence of Subordinated Indebtedness
provided for in subsection 8.2(f)), the Borrower shall prepay the Revolving
Credit Loans and then to the extent necessary, cash collateralize the Letter of
Credit Outstandings in an amount equal to 100% of such Borrowing Base Deficiency
within 90 days after the effective date of the redetermination resulting in 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.
Repayments 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 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

Amended and Restated Credit Agreement
                                       33
<PAGE>
            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.

      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

Amended and Restated Credit Agreement
                                       34
<PAGE>
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 4.13(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 W-8BEN, Form W-8ECI or successors forms, and is
otherwise exempt from IRS interest withholding obligations, 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 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), and if a Person cannot deliver such forms because such Person is
not exempt from U.S. federal withholding tax under the Code as described above,
then such Person shall not become a Lender or Transferee hereunder or a party
hereto.

      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

Amended and Restated Credit Agreement
                                       35
<PAGE>
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

Amended and Restated Credit Agreement
                                       36
<PAGE>
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.

      4.16. Collateral Security

            (a) Closing Date. To secure the performance by the Borrower of the
Obligations hereunder and under the Notes, Security Documents and any Hedging
Agreement, whether now or hereafter incurred, matured or unmatured, direct or
contingent, including extensions, modifications, renewals and increases thereof,
and substitutions therefore, the Borrower shall, as of the Closing Date, have:

                  (i) pursuant to the Pledge Agreement, granted and assigned to
            the Administrative Agent, for the ratable benefit of the Lenders and
            the Hedge Parties, a first priority Lien on all of its shares of
            stock in each domestic Subsidiary and the cash proceeds therefrom;
            and

                  (ii) pursuant to the Mortgages and the Security Agreement,
            granted and assigned to the Administrative Agent, for the ratable
            benefit of the Lenders and the Hedge Parties, a first priority Lien,
            subject only to Permitted Liens, on not less than 75% of the Present
            Value of the Oil and Gas Properties of the Borrower and its
            Subsidiaries (the "Continuing 75% Test") and all of their personal
            property, related assets and the cash proceeds of all of the
            foregoing.

            (b) Subsequently Acquired Property. If the Borrower or any of its
Subsidiaries (or newly organized Subsidiaries) shall, following the Closing
Date, acquire additional Oil and Gas Properties, the Borrower shall grant
security interests and mortgage Liens to the Administrative Agent, for the
ratable benefit of the Lenders and the Hedge Parties, in and on any such
property as provided in Section 7.9 hereof.

            (c) Form of Security Documents. The granting and assigning of such
security interests and Liens by the Borrower and each of its Subsidiaries shall
be pursuant to the Security Documents in form and substance reasonably
satisfactory to the Administrative Agent.

            (d) Title Work. As of the Closing Date, the Borrower shall have
furnished to the Administrative Agent title documents reasonably satisfactory to
the Administrative Agent with respect to the title and Lien status of at least
70% of the Present Value of the Oil and Gas Properties of the Borrower and its
Subsidiaries. At or prior to the addition of any subsequently acquired Oil and
Gas Properties to the collateral pursuant to Section 4.16(b) above, the Borrower
shall furnish to the Administrative Agent title documents reasonably
satisfactory to the Administrative Agent with respect to the title and Lien
status of a sufficient number of subsequently acquired Oil and Gas Properties so
that the Administrative Agent shall at all times have title documents with
respect to at least 70% of the Present Value of the Oil and Gas Properties of
the Borrower and its Subsidiaries (the "Continuing 70% Test"). If at any time
after the Closing Date, the Borrower fails to provide title documents reasonably
satisfactory to the Administrative Agent for a sufficient number of Oil and Gas
Properties to meet the Continuing 70% Test, such failure shall not constitute an
Event of Default, but the Administrative Agent

Amended and Restated Credit Agreement
                                       37
<PAGE>
may redetermine the Borrowing Base by written notice to the Borrower as required
to bring the Borrower into compliance with the Continuing 70% Test until such
title documents are provided. Without regard to whether the Borrower or any
Subsidiary provides satisfactory title documents with respect to a particular
Oil and Gas Property owned by such Person, such Oil and Gas Property shall, if
necessary to meet the requirements of Section 7.9 hereof, be encumbered by a
Mortgage in favor of the Administrative Agent for the ratable behalf of the
Lenders and the Hedge Parties, and shall be included in the collateral.

            (e) Security for Hedging Agreements. The Administrative Agent and
the Lenders agree that upon execution and delivery of a Hedging Agreement by a
Hedge Party, such Hedge Party shall possess a pari passu Lien in the collateral
provided in the Security Documents and the cash proceeds therefrom as security
for the obligations of the Borrower and the other Subsidiaries under the Hedging
Agreement.

                                   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 that:

      5.1. Financial Condition. (a) (i) The consolidated balance sheet of the
Borrower and its consolidated Subsidiaries at December 31, 2003 and the related
consolidated statements of operations, of cash flows and of changes in
stockholders' equity for the fiscal year ended on such date, together with the
related notes and schedules thereto, reported on by BDO Seidman, and (ii) the
unaudited consolidated balance sheet of the Borrower and its consolidated
Subsidiaries as at September 30, 2004, in each case, together with the related
consolidated statements of operations, of cash flow, and of changes in
stockholders' equity for each of the fiscal quarters then ended, in each case
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 as at such dates, and the consolidated results of
their operations and their consolidated cash flows for the respective periods
then ended, in conformity with GAAP.

            (b) All such financial statements referred to in subsection 5.1(a),
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, 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 is not
disclosed in the financial statements referred to in subsection 5.1(a) or in the
notes thereto to the extent required by GAAP.

      5.2. No Change. (a) Since September 30, 2004, there has been no
development, circumstance or event which has had or could reasonably be expected
to have a Material Adverse Effect (provided that any change in non-cash charges
or expenses accrued by the Borrower to

Amended and Restated Credit Agreement
                                       38
<PAGE>
meet ceiling test levels in conformity with Securities and Exchange Commission
Regulation S-X article 4-10(C)(4), in and of itself, shall not be deemed to be a
violation of this subsection 5.2(a)), and (b) during the period from January 1,
2004 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 disclosed in the Borrower's Form 10-Q for the quarter ended September 30,
2004, 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.

                                       39
<PAGE>
      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.

      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. 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, and (iii) 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 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

Amended and Restated Credit Agreement
                                       40
<PAGE>
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 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 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 U-1 referred
to in said Regulation U. The Loans and other transactions contemplated hereunder
will not violate the provisions of Regulations T and X.

      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

Amended and Restated Credit Agreement
                                       41
<PAGE>
"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 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 certain indebtedness of the Borrower
arising under the Existing Credit Facility, and to pay fees and expenses related
thereto, (b) to repay the Fortis Subordinated Debt, and (c) 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, including (without
limiting the generality of the foregoing) the exploration, exploitation,
development and acquisition of Oil and Gas Properties.

      5.17. Environmental Matters. Except as set forth on Schedule 5.17, and
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
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.

                                       42
<PAGE>
            (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,

perfection of the within security interest in such cash collateral account.
Except as expressly provided above in this Section, presentment, demand, protest
and all other notices of any kind are hereby expressly waived.

                                   SECTION 10
                        THE ADMINISTRATIVE AGENT; OTHERS

         10.1. Appointment. Each Lender hereby irrevocably designates and
appoints Fortis as Administrative Agent of such Lender under this Agreement and
the other Loan Documents, and each such Lender irrevocably authorizes the
Administrative Agent, in such capacity, to take such action on its behalf under
the provisions of this Agreement and the other Loan Documents and to exercise
such powers and perform such duties as are expressly delegated to the
Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement, the Administrative Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the
Administrative Agent.

         10.2. Delegation of Duties. The Administrative Agent may execute any of
its duties under this Agreement and the other Loan Documents by or through
agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or attorneys
in-fact selected by it with reasonable care.

         10.3. Exculpatory Provisions. Neither the Administrative Agent nor any
of its officers, directors, employees, agents, attorneys-in-fact or Affiliates
shall be (i) liable for any action lawfully taken or omitted to be taken by it
or such Person under or in connection with this Agreement or any other Loan
Document (except for its or such Person's own gross negligence or willful
misconduct) or (ii) responsible in any manner to any of the Lenders for any
recitals, statements, representations or warranties made by any Loan Party 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 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,

                                       67
<PAGE>
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 Required Lenders is expressly required
hereunder, such Lenders or Required 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 deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of

                                       68
<PAGE>
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. The
Administrative Agent may be removed at any time with or without cause

                                       69
<PAGE>
by the Required Lenders (which for this purpose, shall not include the Loans or
Commitments of the Administrative Agent), provided that on the effectiveness of
such removal the Obligations owing to such Administrative Agent as a Lender are
repaid in full and as an Issuing Lender are cash collateralized or otherwise
secured. If the Administrative Agent is removed, the procedures set forth in
this Section 10.9 shall apply in appointing a successor Administrative Agent.

         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.

         10.11. Others. None of the Sole Lead Arranger, the Bookrunner, the
Syndication Agent, or the Documentation Agent, in such respective capacities,
shall have any duties or responsibilities, or incur any liabilities, under this
Agreement or the other Loan Documents.

                                   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 principal 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 principal amount or extend the expiration date of any
Lender's Commitments, or change the limits on Letter of Credit Outstandings as
set forth in subsection 3.1(a)(i), in each case without the consent of each
Lender affected thereby, (ii) amend, modify or waive any provision of this
subsection or reduce the percentage specified in the definition of Required
Lenders or the Required 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 Required 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, (v) amend, modify or waive any
provision of Section 10 without the written consent of the then

                                       70
<PAGE>
Administrative Agent and Issuing Lender, (vi) amend, modify or waive any
provision of Section 8.16 without the written consent of the Required Lenders or
(vii) amend, modify or waive any provision of this Agreement or any other Loan
Document prior to the initial Borrowing Date without the written consent of each
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.

provided that any notice, request or demand to or upon the Administrative Agent
or the Lenders pursuant to subsection 2.2, 4.3, 4.5 or 4.8 shall not be
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.

reimburse the Administrative Agent, the Sole Lead Arranger, the Bookrunner, the
Syndication Agent, the Documentation Agent and their 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, 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, the

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

Agent and the Documentation 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,

                                       72
<PAGE>
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, the Sole Lead Arranger, the Bookrunner, the Syndication
Agent, the Documentation 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
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

                                       73
<PAGE>
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 any Affiliate thereof or, with the
prior written consent of the Administrative Agent and the Borrower (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 $1,000,000 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 (which shall not be
unreasonably withheld). 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 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

                                       74
<PAGE>
each Person whose name is 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

                                       75
<PAGE>
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.

                  (h) Notwithstanding anything to the contrary contained herein,
any Lender (a "Granting Lender") may grant to a special purpose funding vehicle
that is an Affiliate of such Lender (a "SPC"), identified as such in writing
from time to time by the Granting Lender to the Administrative Agent and the
Borrower, the option to provide to the Borrower all or any part of any Loan that
such Granting Lender would otherwise be obligated to make to the Borrower
pursuant to this Agreement; provided that (i) nothing herein shall constitute a
commitment by any SPC to make any Loan, and (ii) if an SPC elects not to
exercise such option or otherwise fails to provide all or any part of such Loan,
the Granting Lender shall be obligated to make such Loan pursuant to the terms
hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of
the Granting Lender to the same extent, and as if, such Loan were made by such
Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for
any indemnity or similar payment obligation under this Agreement (all liability
for which shall remain with the Granting Lender). In furtherance of the
foregoing, each party hereto hereby agrees (which agreement shall survive the
termination of this Agreement) that, prior to the date that is one year and one
day after the payment in full of all outstanding commercial paper or other
senior indebtedness of any SPC, it will not institute against, or join any other
person in instituting against, such SPC any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings under the laws of the United
States or any State thereof. In addition, notwithstanding anything to the
contrary contained in this Section 11.6(h), any SPC may (i) with notice to, but
without the prior written consent of, the Borrower and the Administrative Agent
and without paying any processing fee therefor, assign all or a portion of its
interests in any Loans to the Granting Lender or to any financial institutions
(consented to by the Borrower and Agent) providing liquidity and/or credit
support to or for the account of such SPC to support the funding or maintenance
of Loans and (ii) disclose on a confidential basis any non-public information
relating to its Loans to any rating agency, commercial paper dealer or provider
of any surety, guarantee or credit or liquidity enhancement to such SPC. This
section may not be amended without the written consent of the SPC. Nothing in
this section in any way affects the Granting Lender's obligations under this
Agreement.

         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 subsection 9(f), or
otherwise), in a greater proportion 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.

                                       76
<PAGE>
                  (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 TEXAS.

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

                  (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
Texas, and federal courts sitting therein, 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

                                       77
<PAGE>
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, the Borrower 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 the
Borrower may continue to receive from the purchasers of production all such
Production Proceeds, and the Administrative Agent shall reasonably cooperate
with the Borrower so that the purchasers of production pay such Production
Proceeds directly to the Borrower and not to the Administrative 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 the Borrower 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

                                       78
<PAGE>
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 the Borrower 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.

         11.18. Existing Indebtedness. The Borrower, the Administrative Agent
and the Lenders have agreed that this Agreement is an amendment and restatement
of the Existing Credit Facility, not a new or substitute credit agreement or
novation of the Existing Credit Facility, and each

                                       79
<PAGE>
reference to an "Extension of Credit" shall include each Extension of Credit
made or issued heretofore under the Existing Credit Facility as well as each
Extension of Credit made or issued hereafter under this Agreement.

         11.19. USA Patriot Act Notice. Each Lender and the Administrative Agent
(for itself and not on behalf of any Lender) hereby notifies the Borrower that
pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56
(signed into law October 26, 2001)) (the "Act"), it is required to obtain,
verify and record information that identifies the Borrower, which information
includes the name and address of the Borrower and other information that will
allow such Lender or the Administrative Agent, as applicable, to identify the
Lender in accordance with the Act.
