(before and after judgment) at the Default Rate.

        2.7     PREPAYMENTS. Borrower shall have the right at its option, from
time to time, to prepay the Loan in whole or part without premium or penalty at

with their respective terms and provisions will conflict with, or result in a
material breach of the terms, conditions or provisions of, or constitute a
default under, or result in any material violation of, or result in the creation

authority and legal right to own and operate the properties which it now owns

and to the knowledge of Borrower has good and defensible title to all of its
assets. The Borrower has full power, authority and legal right to execute and
deliver and to perform and observe the provisions of this Agreement and the
other Loan Documents and the Loan Documents constitute the legal, valid and
binding obligations of the Borrower, enforceable against it in accordance with
their respective terms, subject only to applicable bankruptcy, insolvency or
similar laws and general principles of equity.

        6.5     CORPORATE AUTHORIZATION. The Borrower has duly authorized the

following events shall constitute an Event of Default (whether such occurrence
shall be voluntary or involuntary or come about or be effected by operation of
Law or otherwise):

due on the Note, or fail to pay any other fee, charge or assessment within five
(5) days after the same shall become due and payable (whether by extension,
renewal, acceleration, maturity or otherwise); or

                (b)     Any representation, warranty or certification of the
Borrower made herein, or in any other writing furnished in connection with or
pursuant to any of the Loan Documents shall have been incorrect, false or
misleading in any material respect on the date when made; or

                (c)     The Borrower shall fail to duly observe, perform or
comply with any covenant, agreement or term (other than payment provisions which
are governed by subparagraph (a) hereof) contained in this Agreement or any of
the Loan Documents and such default or breach shall have not been cured or
remedied within thirty (30) days following the date the Lender first notifies
the Borrower in writing; or

                (d)     Any of the following: (i) the Borrower shall be unable
to pay its debts as they mature, or shall make an assignment for the benefit of
creditors or admit in writing its inability to pay its debts generally as they
become due or fail generally to pay its debts as they mature; or (ii) an order,
judgment or decree is entered adjudicating the Borrower insolvent or an order
for relief under the United States Bankruptcy Code is entered with respect to
the Borrower; or (iii) the Borrower shall petition or apply to any Tribunal for
the appointment of a trustee, receiver, custodian or liquidator of the Borrower
or of any substantial part of the assets of the Borrower or shall commence any
proceedings relating to the Borrower under any bankruptcy, reorganization,
compromise, arrangement, insolvency, readjustment of debts, dissolution, or
liquidation Law of any jurisdiction, whether now or hereafter in effect; or (iv)
any such petition or application shall be filed, or any such proceedings shall
be commenced, against the Borrower and the Borrower by any act shall indicate
its approval thereof, consent thereto or acquiescence therein, or an order,
judgment or decree shall be entered appointing any such trustee, receiver,
custodian or liquidator, or approving the petition in any such proceedings, and
such order, judgment or decree shall remain unstayed and in effect for more than
thirty (30) days; or (v) the Borrower shall fail to make timely payment or
deposit of any amount of tax required to be withheld by such Borrower and paid
to or deposited to or to the credit of the United States of America pursuant to
the provisions of the Internal Revenue Code of 1986, as amended, in respect of
any and all wages and salaries paid to employees of the Borrower; or

                (e)     Any default or event of default under any of the other
Loan Documents following the lapse of any applicable curative or grace period
provided therein.

        7.2     REMEDIES. Upon the occurrence of any Event of Default referred
to in Section 7.1, the Note and all other Indebtedness shall be immediately due
and payable, without notice of any kind. Upon the occurrence of any other Event
of Default, and without prejudice to any right or remedy of the Lender under
this Agreement or the Loan Documents or under applicable Law or under any other
instrument or document delivered in connection herewith, the Lender may declare
the Note and the Indebtedness, or any part thereof, to be forthwith due and
payable, whereupon the Note and the other Indebtedness, or such portion as is
designated by the Lender shall forthwith become due and payable, without
presentment, demand, notice or protest of any kind, all of which are hereby
expressly waived by the Borrower. No delay or omission on the part of the Lender
in exercising any power or right hereunder or under the Note, the Loan Documents
or under

                                 Loan Agreement
                                    Page 10
<PAGE>

applicable law shall impair such right or power or be construed to be a waiver
of any default or any acquiescence therein, nor shall any single or partial
exercise by Lender of any such power or right preclude other or further exercise
thereof or the exercise of any other such power or right by such Person. In the
event that all or part of the Indebtedness becomes or is declared to be
forthwith due and payable as herein provided, Lender shall have the right to set
off the amount of all the Indebtedness of the Borrower owing to such Person
against, and shall have a lien upon and security interest in, all property of
the Borrower in such Person's possession at or subsequent to such default,
regardless of the capacity in which such property is held, including but not
limited to any balance or share of any deposit, demand, collection or agency
account. At any time after the occurrence of any Event of Default, the Lender
may, at its option, cause an audit of any and/or all of the books, records and
documents of the Borrower to be made by auditors satisfactory to the Lender at
the expense of the Borrower. The Lender also shall have, and may exercise, each
and every right and remedy granted to it for default under the terms of the
other Loan Documents.

        7.3     APPLICATION OF PROCEEDS. After the exercise of remedies provided
for in Section 7.2 (or after the Indebtedness automatically becomes immediately
due and payable as set forth in Section 7.2), any amounts received on account of
such Indebtedness shall be applied in the following order:

        FIRST: to payment of that portion of the Indebtedness constituting fees,
        indemnities, expenses or other amounts (other than principal and
        interest) payable to the Lender (including fees, charges and
        disbursements of counsel);

        SECOND: to payment of accrued and unpaid interest on the Indebtedness;

        THIRD: to payment of unpaid principal of the Indebtedness;

        and

        LAST: the balance, if any, after all of the Indebtedness has been
        indefeasibly paid in full, to Borrower or as otherwise required by
        applicable Laws.

        8.2     PLACE OF PAYMENT. All sums payable hereunder shall be paid in
immediately available funds, at such location as may be designated from time to
time in writing by Lender. If any interest, principal or other payment falls due
on a date other than a Business Day, then (unless otherwise provided herein)
such due date shall be extended to the next succeeding Business Day, and such
extension of time will, in such case, be included in computing interest, if any,
in connection with such payment.

        8.3     SURVIVAL OF AGREEMENTS. All covenants, agreements,
representations and warranties made herein shall survive the execution and the
delivery of Loan Documents.

        8.4     PARTIES IN INTEREST. All covenants, agreements and obligations
contained in this Agreement shall bind and inure to the benefit of the parties
hereto and the respective successors and permitted assigns of the parties
hereto, except that the Borrower may not assign any of its rights or obligations
hereunder or under the Note without the prior written consent of the Lender.

        8.5     GOVERNING LAW. This Agreement and the Note shall be deemed to
have been made or incurred under the Laws of the State of Texas and shall be
construed and enforced in accordance with and governed by the Laws of Texas
except only where the applicable remedial or

                                 Loan Agreement
                                    Page 12
<PAGE>

procedural laws of the other jurisdictions are situated are applicable thereto.
Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch 15 (which regulates certain revolving
credit loan accounts and revolving tri-party accounts) shall not apply to this
Agreement or the Note.

        8.6     INTEREST. It is the intention of the parties hereto that the
Lender shall conform strictly to usury laws applicable to them. Accordingly, if
the transactions contemplated hereby would be usurious as to the Lender under
laws applicable to it (including the laws of the United States of America or any
other jurisdiction whose laws may be mandatorily applicable the Lender
notwithstanding the other provisions of this Agreement), then, in that event,
notwithstanding anything to the contrary in any of the Loan Documents, it is
agreed as follows: (i) the aggregate of all consideration which constitutes
interest under law applicable to the Lender that is contracted for, taken,
reserved, charged or received by the Lender under any of the Loan Documents or
agreements or otherwise in connection with the Note shall under no circumstances
exceed the Maximum Rate, and any excess shall be canceled automatically and if
theretofore paid shall be credited by such Lender on the principal amount of the
Indebtedness (or, to the extent that the principal amount of the Indebtedness
shall have been or would thereby be paid in full, refunded by any Lender to the
Borrower); and (ii) in the event that the maturity of the Note is accelerated by
reason of an election of the holder thereof resulting from any Event of Default
under this Agreement or otherwise, or in the event of any required or permitted
prepayment, then such consideration that constitutes interest under law
applicable to the Lender may never include interest greater than the Maximum
Rate, and excess interest, if any, provided for in this Agreement or otherwise
shall be canceled automatically as of the date of such acceleration or
prepayment and, if theretofore paid, shall be credited by the Lender on the
principal amount of the Indebtedness (or, to the extent that the principal
amount of the Indebtedness shall have been or would thereby be paid in full,
refunded by the Lender to the Borrower). All sums paid or agreed to be paid to
the Lender for the use, forbearance or detention of sums due hereunder shall, to
the extent permitted by law, be amortized, prorated, allocated and spread
throughout the full term of the Loans evidenced by the Note until payment in
full so that the rate or amount of interest on account of any Loans hereunder
does not exceed the Maximum Rate. If at any time and from time to time (i) the
amount of interest payable to the Lender on any date shall be computed at the
highest lawful rate applicable to the Lender pursuant to this Section 8.6; and
(ii) in respect of any subsequent interest computation period the amount of
interest otherwise payable to Lender would be less than the amount of interest
payable to the Lender computed at the highest lawful rate applicable to the
Lender, then the amount of interest payable to the Lender in respect of such
subsequent interest computation period shall continue to be computed at the
highest lawful rate applicable to the Lender until the total amount of interest
payable to the Lender shall equal the total amount of interest which would have
been payable to the Lender if the total amount of interest had been computed
without giving effect to this Section 8.6. To the extent that the Texas Credit
Title (V.T.C.A., Texas Finance Code ss.ss. 301.001 et seq.) is relevant to the
Lender for the purpose of determining the highest lawful rate, the Lender hereby
elects to determine the applicable ceiling rate under the Texas Credit Title by
the weekly ceiling from time to time in effect.

        8.7     NO WAIVER, CUMULATIVE REMEDIES. No failure to exercise, and no
delay in exercising, on the part of the Lender, any right, power or privilege
hereunder or under any other Loan Document or applicable Law shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege of the Lender. The rights and remedies herein

                                 Loan Agreement
                                    Page 13
<PAGE>

provided are cumulative and not exclusive of any other rights or remedies
provided by any other instrument or by law. No notice to or demand on the
Borrower in any case shall entitle the Borrower to any other or further notice
or demand in similar or other circumstances.

        8.8     COSTS. The Borrower agrees to pay to the Lender on demand all
recording fees and filing costs, all reasonable attorneys fees and reasonable
legal expenses incurred or accrued by the Lender in connection with and
preparation, negotiation, closing, administration, perfection, enforcement,
refinancing, renegotiation, restructuring, amendment, waiver or other
modifications of this Agreement and the Loan Documents or any amendment, waiver,
consent or modification to and of the Loan Documents. In any action to enforce
or construe the provisions of this Agreement or any of the Loan Documents, the
Lender shall be entitled to recover its reasonable attorneys' fees,
disbursements of counsel and all costs and expenses related thereto.

        8.9     RIGHT OF SET - OFF. The Borrower hereby grants to the Lender a
lien, security interest and right of setoff as security for all Indebtedness and
obligations of the Borrower upon and against all deposits, credit, and property
of the Borrower, now or hereafter in the possession, custody, safekeeping or
control of such Person; and upon (a) the occurrence and during the continuance
of any Event of Default; and (b) the decision by the Lender to declare the Note
due and payable pursuant to the provisions of Article VII, the Lender is hereby
authorized at any time and from time to time, to set off and otherwise apply any
and all deposits (general or special, time or demand, provisional or final,
other than trust funds) at any time held and other indebtedness at any time
owing by the Lender to or for the credit or the account of the Borrower against
any and all of the Indebtedness of the Borrower now or hereafter existing under
this Agreement and the Note, irrespective of whether demand under this Agreement
or the Note shall have been made and although such Indebtedness may be
unmatured. The Lender shall promptly notify the Borrower after any such set off
and application; PROVIDED, HOWEVER, that the failure to give such notice shall
not affect the validity of such setoff and application. The rights of the Lender
under this Section are in addition to other rights and remedies (including,
without limitation, other rights of set - off) that such Persons may have at
law, in equity or otherwise.

        8.10    HEADINGS. The article and section headings of this Agreement are
for convenience of reference only and shall not constitute a part of the text
hereof nor alter or otherwise affect the meaning or interpretation of any
provision hereof.

        8.11    SEVERABILITY. The unenforceability or invalidity as determined
by a Tribunal of competent jurisdiction, of any provision or provisions of this
Agreement shall not render unenforceable or invalid any other provision or
provisions hereof.

        8.12    CONFIDENTIALITY. In the event that the Borrower provides to the
Lender written confidential information belonging to the Borrower, the Lender
shall thereafter maintain such information in confidence in accordance with the
standards of care and diligence that each utilizes in maintaining its own
confidential information. This obligation of confidence shall not apply to such
portions of the information which (i) are in the public domain; (ii) hereafter
become part of the public domain, without the Lender breaching its obligation of
confidence to the Borrower; (iii) are previously known by the Lender from some
source other than the Borrower; (iv) are hereafter developed by the Lender
without using the Borrower's information; (v) are hereafter obtained by the
Lender from a third party who owes no obligation of confidence to the Borrower
with respect

                                 Loan Agreement
                                    Page 14
<PAGE>

to such information; (vi) are disclosed with the Borrower's consent; (vii) must
be disclosed either pursuant to any Governmental Requirement or to Persons
regulating the activities of the Lender; or (viii) as may be required by law or
regulation or order of any Governmental Authority in any judicial, arbitration
or governmental proceeding. Further, the Lender may disclose any such
information to consultants, any independent certified public accountants or any
legal counsel employed by such Persons in connection with this Agreement,
including without limitation, the enforcement or exercise of all rights and
remedies thereunder, or any assignee or participant (including prospective
assignees and participants) in the Loan; provided, however, that the Lender
imposes on the Person to whom such information is disclosed the same obligation
to maintain the confidentiality of such information as is imposed upon it
hereunder. Notwithstanding anything to the contrary provided herein, this
obligation of confidence shall cease two (2) years from the date the information
was furnished, unless the Borrower requests in writing at least thirty (30) days
prior to the expiration of such two (2) year period, to maintain the
confidentiality of such information for an additional two (2) year period. The
Lender agrees not to issue or cause to be issued any tombstone or other publicly
published announcement of the lending facilities established by this Agreement
without the Borrower's review and approval thereof, which such approval will not
be unreasonably withheld.

        8.13    SURVIVAL. To the extent that any payments on the Indebtedness
are subsequently invalidated, declared to be fraudulent or preferential, set
aside or required to be repaid to a trustee, debtor-in-possession, receiver or
other Person under any bankruptcy law, common law or equitable cause, then to
such extent, the Indebtedness so satisfied shall be revived and continue as if
such payment or proceeds had not been received and the Liens, security
interests, rights, powers and remedies under this Agreement shall continue in
full force and effect.

        8.14    NO ORAL AGREEMENTS. THE LOAN DOCUMENTS EMBODY THE ENTIRE
AGREEMENT AND UNDERSTANDING BETWEEN THE PARTIES AND SUPERSEDE ALL OTHER
AGREEMENTS AND UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE SUBJECT
MATTER HEREOF AND THEREOF THE LOAN DOCUMENTS 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
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

        8.15    COUNTERPARTS. This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument and any of the parties hereto may execute this Agreement by signing
any such counterpart. Delivery of an executed counterpart of a signature page to
this Agreement by telecopier shall be as effective as delivery of a manually
executed counterpart of this Agreement.

        8.16    AMENDMENTS. No amendment or waiver of any provision of this
Agreement, the Note, or any other Loan Document to which the Borrower is a
party, nor any consent to any departure by the Borrower therefrom, shall in any
event be effective unless the same shall be agreed or consented to by the Lender
and the Borrower, and each such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided, that
no amendment, waiver, or consent shall, unless in writing and signed by the
Lender and the Borrower, do any of the following: (a) reduce the principal of,
or interest on, the Note or any fees

                                 Loan Agreement
                                    Page 15

or other amounts payable hereunder; (b) postpone any date fixed for any payment
of principal of, or interest on, the Note or any fees or other amounts payable
hereunder; (c) change the percentage of the Commitment or of the aggregate
unpaid principal amount of the Note; or (d) change any provision contained in
this Section 8.16.

        8.17    SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns. The Borrower may not assign or transfer any of its rights or
obligations hereunder without the prior written consent of the Lender. The
Borrower and the Lender agree that the Lender may at any time assign to one or
more assignees all, or a proportionate part of all, of its rights and
obligations under this Agreement and the other Loan Documents.

executed and delivered to the Lender, effective as of the day and year first

        Section 2.01    Loans and Letters of Credit.

                (a)     Loans. Each Lender severally agrees, on the terms and
        conditions of this Agreement, to make loans to Borrower during the
        period from and including (i) the Closing Date or (ii) such later date
        that such Lender becomes a party to this Agreement as provided in
        Section 12.06(b), to and up to, but excluding, the Revolving Credit
        Termination Date in an aggregate principal amount at any one time
        outstanding up to, but not exceeding, the amount of such Lender's
        Commitment as then in effect; provided, however, that the aggregate
        principal amount of all such Loans by all Lenders hereunder at any one
        time outstanding together with the LC Exposure shall not exceed the
        Aggregate Commitments. Subject to the terms of this Agreement, during
        the period from the Closing Date to and up to, but excluding, the
        Revolving Credit Termination Date, Borrower may borrow, repay and
        reborrow the amount described in this Section 2.01(a).

                (b)     Letters of Credit. During the period from and including
        the Closing Date to, but excluding, the Revolving Credit Termination
        Date, the Issuing Bank, as issuing bank for the Lenders, agrees to
        extend credit for the account of Borrower or any Subsidiary at any time
        and from time to time by issuing, renewing, extending or reissuing
        Letters of Credit; provided, however, the LC Exposure at any one time
        outstanding shall not exceed the lesser of (i) the LC Commitment and
        (ii) the Aggregate Commitments, as then in effect, minus the aggregate
        principal amount of all Loans then outstanding. The Lenders shall
        participate in such Letters of Credit according to their respective
        Percentage Shares. Each of the Letters of Credit shall (i) be issued by
        the Issuing Bank, (ii) contain such terms and provisions as are
        reasonably required by

                                       14

<PAGE>

        the Issuing Bank, (iii) be for the account of Borrower or a Subsidiary
        and (iv) expire not later than the Revolving Credit Termination Date.

                (c)     Limitation on Types of Loans. Subject to the other terms
        and provisions of this Agreement, at the option of Borrower, the Loans
        may be Base Rate Loans or LIBOR Loans; provided that, without the prior
        written consent of the Majority Lenders, no more than three (3) LIBOR
        Loans may be outstanding at any time.

        Section 2.02    Borrowings, Continuations and Conversions, Letters of
Credit.

                (a)     Borrowings. Borrower shall give Administrative Agent
        (which shall promptly notify the Lenders) advance notice as hereinafter
        provided of each borrowing hereunder, which shall specify (i) the
        aggregate amount of such borrowing, (ii) the Type and (iii) the date
        (which shall be a Business Day) of the Loans to be borrowed, and (iv)
        (in the case of LIBOR Loans) the duration of the Interest Period
        therefor.

                (b)     Minimum Amounts. All Base Rate Loan borrowings shall be
        in amounts of at least $500,000 or the remaining balance of the
        Aggregate Commitments, if less, or any whole multiple of $100,000 in
        excess thereof, and all LIBOR Loans shall be in amounts of at least
        $1,000,000 or any whole multiple of $500,000 in excess thereof.

                (c)     Notices. All borrowings, continuations and conversions
        shall require advance written notice to Administrative Agent (which
        shall promptly notify the Lenders) in the form of Exhibit B (or
        telephonic notice promptly confirmed by such a written notice), which in
        each case shall be irrevocable and accompanied by a Compliance
        Certificate (excluding the information required by clauses (f) and (g)
        thereof) from Borrower, to be received by Administrative Agent not later
        than 11:00 a.m. Houston, Texas time at least one Business Day prior to
        the date of each Base Rate Loan borrowing and three Business Days prior
        to the date of each LIBOR Loan borrowing, continuation or conversion.
        Without in any way limiting Borrower's obligation to confirm in writing
        any telephonic notice, Administrative Agent may act without liability
        upon the basis of telephonic notice believed by Administrative Agent in
        good faith to be from Borrower prior to receipt of written confirmation.
        In each such case, Borrower hereby waives the right to dispute
        Administrative Agent's record of the terms of such telephonic notice
        except in the case of gross negligence or willful misconduct by
        Administrative Agent.

                (d)     Continuation Options. Subject to the provisions made in
        this Section 2.02(d), Borrower may elect to continue all or any part of
        any LIBOR Loan beyond the expiration of the then current Interest Period
        relating thereto by giving advance notice as provided in Section 2.02(c)
        to Administrative Agent (which shall promptly notify the Lenders) of
        such election, specifying the amount of such Loan to be continued and
        the Interest Period therefor. In the absence of such a timely and proper
        election, Borrower shall be deemed to have elected to convert such LIBOR
        Loan to a Base Rate Loan pursuant to Section 2.02(e). All or any part of
        any LIBOR Loan may be continued as provided herein, provided that (i)
        any continuation of any such Loan shall be (as to each Loan as continued
        for an applicable Interest Period) in amounts of at least $1,000,000 or
        any whole multiple of $500,000 in excess thereof and (ii) no Default
        shall have occurred and be continuing. If a Default shall have occurred
        and be continuing, each LIBOR Loan shall be converted to a Base Rate
        Loan on the last day of the Interest Period applicable thereto.

                (e)     Conversion Options. Borrower may elect to convert all or
        any part of any LIBOR Loan on the last day of the then current Interest
        Period relating thereto to a Base Rate Loan by giving advance notice to
        Administrative Agent (which shall promptly notify the

                                       15

<PAGE>

        Lenders) of such election. Subject to the provisions made in this
        Section 2.02(e), Borrower may elect to convert all or any part of any
        Base Rate Loan at any time and from time to time to a LIBOR Loan by
        giving advance notice as provided in Section 2.02(c) to Administrative
        Agent (which shall promptly notify the Lenders) of such election. All or
        any part of any outstanding Loan may be converted as provided herein,
        provided that (i) any conversion of any Base Rate Loan into a LIBOR Loan
        shall be (as to each such Loan into which there is a conversion for an
        applicable Interest Period) in amounts of at least $1,000,000 or any
        whole multiple of $500,000 in excess thereof and (ii) no Default shall
        have occurred and be continuing. If a Default shall have occurred and be
        continuing, no Base Rate Loan may be converted into a LIBOR Loan.

                (f)     Advances. Not later than 11:00 a.m. Houston, Texas time
        on the date specified for each borrowing hereunder, each Lender shall
        make available the amount of the Loan to be made by it on such date to
        Administrative Agent, to an account which Administrative Agent shall
        specify, in immediately available funds, for the account of Borrower.
        The amounts so received by Administrative Agent shall, subject to the
        terms and conditions of this Agreement, be made available to Borrower by
        depositing the same, in immediately available funds, in an account of
        Borrower, designated by Borrower and maintained at the Principal Office.

                (g)     Letters of Credit. Borrower shall give the Issuing Bank
        (which shall promptly notify the Lenders of such request and their
        Percentage Share of such Letter of Credit) advance notice to be received
        by the Issuing Bank not later than 11:00 a.m. Houston, Texas time not
        less than three (3) Business Days prior thereto of each request for the
        issuance, and at least thirty (30) Business Days prior to the date of
        the renewal or extension, of a Letter of Credit hereunder which request
        shall specify (i) the amount of such Letter of Credit, (ii) the date
        (which shall be a Business Day) such Letter of Credit is to be issued,
        renewed or extended, (iii) the duration thereof, (iv) the name and
        address of the beneficiary thereof, (v) the type of the Letter of Credit
        and (vi) such other information as the Issuing Bank may reasonably
        request, all of which shall be reasonably satisfactory to the Issuing
        Bank. Subject to the terms and conditions of this Agreement, on the date
        specified for the issuance, renewal or extension of a Letter of Credit,
        the Issuing Bank shall issue, renew or extend such Letter of Credit to
        the beneficiary thereof.

                In conjunction with the issuance of each Letter of Credit,
        Borrower and the Subsidiary, if the account party, shall execute a
        Letter of Credit Agreement. In the event of any conflict between any
        provision of a Letter of Credit Agreement and this Agreement, Borrower,
        the Issuing Bank, Administrative Agent and the Lenders hereby agree that
        the provisions of this Agreement shall govern.

                The Issuing Bank will send to Borrower and each Lender, promptly
        upon issuance of any Letter of Credit, or an amendment thereto, a true
        and complete copy of such Letter of Credit, or such amendment thereto.

        Section 2.03    Changes of Commitments.

                (a)     The Aggregate Commitments shall at all times be equal to
        the lesser of (i) the Aggregate Maximum Revolving Credit Amounts after
        adjustments resulting from reductions pursuant to Section 2.03(b) or
        (ii) the Borrowing Base as determined from time to time.

                (b)     Borrower shall have the right to terminate or to reduce
        the amount of the Aggregate Maximum Revolving Credit Amounts at any
        time, or from time to time, upon not less than three (3) Business Days'
        prior notice to Administrative Agent (which shall promptly notify the
        Lenders) of each such termination or reduction, which notice shall
        specify the effective date thereof and the amount of any such reduction
        (which shall not be less than $1,000,000 or any

                                       16

<PAGE>

        whole multiple of $500,000 in excess thereof) and shall be irrevocable
        and effective only upon receipt by Administrative Agent.

                (c)     The Aggregate Maximum Revolving Credit Amounts once
        terminated or reduced may not be reinstated.

        Section 2.04    Fees.

                (a)     Commitment Fee. Borrower shall pay to Administrative
        Agent for the account of each Lender a commitment fee on the daily
        average unused amount of the Aggregate Commitments for the period from
        and including the Closing Date up to, but excluding, the earlier of the
        date the Aggregate Commitments are terminated or the Revolving Credit
        Termination Date at a rate per annum equal to the applicable percentage
        set forth at the appropriate intersection in the table shown below,
        based on the Borrowing Base Utilization as in effect from time to time:

                BORROWING BASE UTILIZATION     APPLICABLE PERCENTAGE
                ----------------------------   ---------------------
                Less than 75%                          0.375%
                Greater than or equal to 75%           0.500%

                Each change in the applicable percentage resulting from a change
        in the Borrowing Base Utilization shall take effect on the day such
        change in the Borrowing Base Utilization occurs. Accrued commitment fees
        shall be payable quarterly in arrears on each Quarterly Date and on the
        earlier of the date the Aggregate Commitments are terminated or the
        Revolving Credit Termination Date.

                (b)     Letter of Credit Fees.

                        (i)     Borrower agrees to pay Administrative Agent, for
        the account of each Lender, commissions for issuing the Letters of
        Credit on the daily average outstanding of the maximum liability of the
        Issuing Bank existing from time to time under each Letter of Credit
        (calculated separately for each Letter of Credit) at the rate per annum
        equal to the Applicable Margin in effect from time to time for LIBOR
        Loans. Each Letter of Credit shall be deemed to be outstanding up to the
        full face amount of the Letter of Credit until the Issuing Bank has
        received the canceled Letter of Credit or a written cancellation of the
        Letter of Credit from the beneficiary of such Letter of Credit in form
        and substance acceptable to the Issuing Bank, or for any reductions in
        the amount of the Letter of Credit (other than from a drawing), written
        notification from the beneficiary of such Letter of Credit. Such
        commissions are payable quarterly in arrears on each Quarterly Date and
        upon cancellation or expiration of each such Letter of Credit.

                        (ii)    Upon each issuance, renewal or extension of any
        Letter of Credit, Borrower shall pay to Administrative Agent for the
        account of the Issuing Bank an upfront fee equal to the greater of (a)
        0.125% of the face amount of the Letter of Credit and (b) $500.

                        (iii)   Borrower shall pay to the Issuing Bank such
        other usual and customary fees of the Issuing Bank associated with any
        transfers, amendments, drawings, negotiations or reissuances of any
        Letters of Credit.

                (c)     Fee Letter. Borrower shall pay such other fees as are
        set forth in the Fee Letter pursuant to the provisions thereof.

        Section 2.05    Several Obligations. The failure of any Lender to make
any Loan to be made by it or to provide funds for disbursements or
reimbursements under Letters of Credit on the date specified therefor shall not
relieve any other Lender of its obligation to make its Loan or provide funds on
such date, but no Lender shall be responsible for the failure of any other
Lender to make a Loan to be made by such other Lender or to provide funds to be
provided by such other Lender.

        Section 2.06    Notes. The Loans made by each Lender shall be evidenced
by a single promissory note of Borrower in substantially the form of Exhibit A,
dated (i) the Closing Date or (ii) the effective date of an Assignment pursuant
to Section 12.06(b), payable to the order of such Lender in a principal amount
equal to its Maximum Revolving Credit Amount as originally in effect and
otherwise duly completed and such substitute Notes as required by Section
12.06(b). The date, amount, Type, interest rate and Interest Period of each Loan
made by each Lender, and all payments made on account of the principal thereof,
shall be recorded by such Lender on its books for its Note, and, prior to any
transfer may be endorsed by such Lender on a schedule attached to such Note or
any continuation thereof or on any separate record maintained by such Lender.
Failure to make any such notation or to attach a schedule shall not affect any
Lender's or Borrower's rights or obligations in respect of such Loans or affect
the validity of such transfer by any Lender of its Note.

        Section 2.07    Prepayments.

                (a)     Voluntary Prepayments. Borrower may prepay the Base Rate
        Loans upon not less than one (1) Business Day's prior notice to
        Administrative Agent (which shall promptly notify the Lenders), which
        notice shall specify the prepayment date (which shall be a Business Day)
        and the amount of the prepayment (which shall be at least $1,000,000 or
        any whole multiple of $500,000 in excess thereof, or the remaining
        aggregate principal balance outstanding on the Notes if less than
        $1,000,000) and shall be irrevocable and effective only upon receipt by
        Administrative Agent, provided that interest on the principal prepaid,
        accrued to the prepayment date, shall be paid on the prepayment date.
        Borrower may prepay LIBOR Loans on the same conditions as for Base Rate
        Loans (except that prior notice to Administrative Agent shall be not
        less than three (3) Business Days for LIBOR Loans) and in addition such
        prepayments of LIBOR Loans shall be subject to the terms of Section
        5.05.

                (b)     Mandatory Prepayments.

                        (i)     Termination or Reduction of Aggregate Maximum
        Revolving Credit Amounts. If, after giving effect to any termination or
        reduction of the Aggregate Maximum Revolving Credit Amounts pursuant to
        Section 2.03(b), the outstanding aggregate principal amount of the
        Revolving Credit Loans plus the LC Exposure exceeds the Aggregate
        Maximum Revolving Credit Amounts, Borrower shall (i) prepay the Loans on
        the date of such termination or reduction in an aggregate principal
        amount equal to the excess, together with interest on the principal
        amount paid accrued to the date of such prepayment and (ii) if any
        excess remains after prepaying all of the Loans because of LC Exposure,
        pay to Administrative Agent on behalf of the Lenders an amount equal to
        the excess to be held as cash collateral as provided in Section 2.10(b)
        hereof.

                        (ii)    Redetermination of Borrowing Base. Upon any
        redetermination of the amount of the Borrowing Base in accordance with
        Section 2.08, if the redetermined Borrowing Base results in a Borrowing
        Base Deficiency, then Borrower shall within fifteen (15) days of receipt
        of written notice thereof deliver to Agent a written response indicating
        which of the following actions it intends to take to remedy the
        Borrowing Base Deficiency (and the failure of Borrower to deliver such
        election notice or to perform the action chosen to remedy such Borrowing
        Base Deficiency shall constitute an Event of Default):

                                (w)     within thirty (30) days of receipt of
                written notice of the Borrowing Base Deficiency, prepay the
                Loans in an aggregate principal amount sufficient to eliminate
                such Borrowing Base Deficiency, together with interest on the
                principal amount paid accrued to the date of such prepayment;

                                (x)     prepay the Loans in six (6) monthly
                installments equal to one-sixth of such Borrowing Base
                Deficiency (after taking into account any Properties mortgaged
                to Agent pursuant to clause (c) below), with the first such
                installment due 30 days after the date such Borrowing Base
                Deficiency notice is received by Borrower and each of the other
                five installments due 30 days after the preceding installment,
                and make each of such payments within such time periods;

                                (y)     within thirty (30) days of receipt of
                written notice of the Borrowing Base Deficiency, grant to Agent
                a first priority Lien in additional Properties of Borrower,
                which in the Lenders' sole determination, have sufficient loan
                value to eliminate such Borrowing Base Deficiency; or

                                (z)     eliminate the Borrowing Base Deficiency
                through a combination of the actions described in clauses (w) or
                (x) and (y).

                If, because of LC Exposure, a Borrowing Base Deficiency remains
        after prepaying all of the Loans and granting first priority Liens in
        additional Properties to Administrative Agent, Borrower shall pay to
        Administrative Agent on behalf of the Lenders an amount equal to such
        remaining Borrowing Base Deficiency to be held as cash collateral as
        provided in Section 2.10(b).

                (iii)   Monthly Reduction Amount. If any reduction of the amount
        of the Borrowing Base by operation of the Monthly Reduction Amount in
        accordance with Section 2.08 results in a Borrowing Base Deficiency,
        then Borrower shall immediately prepay the Loans in an aggregate
        principal amount equal to such Borrowing Base Deficiency, together with
        interest on the principal amount paid accrued to the date of such
        prepayment. If, because of LC Exposure, a Borrowing Base Deficiency
        remains after prepaying all of the Loans, Borrower shall pay to
        Administrative Agent on behalf of the Lenders an amount equal to such
        remaining Borrowing Base Deficiency to be held as cash collateral as
        provided in Section 2.10(b).

                (iv)    Transfer. If, after a Transfer of any Property to the
        extent allowed by Section 9.12 and the reduction in the Borrowing Base
        pursuant to Section 2.08(f), a Borrowing Base Deficiency exists, then
        Borrower shall, concurrently with the receipt thereof, prepay the Loans
        with the net proceeds received from such Transfer in an amount necessary
        to eliminate such Borrowing Base Deficiency. If, because of LC Exposure,
        a Borrowing Base Deficiency remains after prepaying all of the Loans,
        Borrower shall pay to Administrative Agent on behalf of the Lenders an
        amount equal to such remaining Borrowing Base Deficiency to be held as
        cash collateral as provided in Section 2.10(b). Notwithstanding anything
        in this Agreement to the contrary, if at the time of any permitted
        Transfer a Borrowing Base Deficiency exists, then Borrower shall,
        concurrently with the receipt thereof, prepay the Loans with the net
        proceeds received from such Transfer to the extent necessary to
        eliminate the portion of the Borrowing Base Deficiency resulting from
        such Transfer and such preexisting Borrowing Base Deficiency; and
        Borrower shall remain obligated, pursuant to the terms of this
        Agreement, to eliminate any Borrowing Base Deficiency remaining after
        prepaying the Loans with the net proceeds from such Transfer. If
        Borrower Transfers any Property at such time as a Default exits,
        Borrower shall, concurrently with the receipt of proceeds therefrom,
        prepay the Loans in an amount equal to the

                                       19

<PAGE>

        lesser of (x) the aggregate principal amount outstanding on the Loans
        and (y) 100% of the net proceeds received from such Transfer. The
        preceding sentence shall not be interpreted as permitting the sale of
        any Property at such time as a Default exists without the prior written
        consent of the Lenders.

                (v)     Proceeds from Hedging Agreements. At any time that a
        Default exists, any proceeds received by Borrower under any Hedging
        Agreements, including as a result of the early termination thereof,
        shall be used immediately upon receipt thereof to prepay the Loans in an
        amount equal to the lesser of (x) the aggregate principal amount
        outstanding on the Loans and (y) 100% of the net proceeds received.

                (c)     Generally. Prepayments permitted or required under this
        Section 2.07 shall be without premium or penalty, except as required
        under Section 5.05 for prepayment of LIBOR Loans. Any prepayments on the
        Loans may be reborrowed subject to the then effective Aggregate
        Commitments. Any prepayments made while a Borrowing Base Deficiency
        exists shall be applied first to the Borrowing Base Deficiency and then
        otherwise as provided by the Loan Documents.

        Section 2.08    Borrowing Base.

                (a)     Borrowing Base and Monthly Reduction Amount. The
        Borrowing Base and the Monthly Reduction Amount shall be determined in
        accordance with Section 2.08(b) by Administrative Agent with the
        concurrence of the Lenders and are subject to redetermination in
        accordance with Sections 2.08(d), (e) and (f). Upon any redetermination
        of the Borrowing Base or the Monthly Reduction Amount, such
        redetermination shall remain in effect until the next successive
        Redetermination Date; provided, however, the then effective Borrowing
        Base shall reduce on the last day of each month by the then effective
        Monthly Reduction Amount. So long as any of the Commitments are in
        effect or any LC Exposure or Loans are outstanding hereunder, this
        facility shall be governed by the then effective Borrowing Base and
        Monthly Reduction Amount. During the period from and after the Closing
        Date until the next redetermination pursuant to Sections 2.08(d), (e) or
        (f) or adjusted pursuant to Section 8.08(c), the amount of the Borrowing
        Base shall be $35,300,000, as reduced on a cumulative basis on the last
        day of each month following such effective date by the applicable
        Monthly Reduction Amount. The Monthly Reduction Amount shall be $0.00,
        (or the outstanding principal balance of the Loans, if such balance is
        less than such Monthly Reduction Amount) each month until the next
        redetermination thereof pursuant to Sections 2.08(d), (e) or (f). No
        delay for any reason whatsoever in a redetermination of the Monthly
        Reduction Amount shall affect Borrower's obligations under Section
        2.07(b)(iii).

                (b)     Determination Procedure. Upon receipt of the reports
        required by Section 8.07 and such other reports, data and supplemental
        information as may from time to time be reasonably requested by
        Administrative Agent (the "Engineering Reports"), Administrative Agent
        will redetermine the Borrowing Base and the Monthly Reduction Amount.
        Such redetermination will be in accordance with its normal and customary
        practices and procedures for evaluating oil and gas reserves and other
        related assets as such exist at that particular time, and may also take
        into consideration the financial condition, Debt, and business of
        Borrower and its Subsidiaries and such other factors as Administrative
        Agent customarily deems appropriate. Administrative Agent, in its sole
        discretion, may make adjustments to the rates, volumes and prices and
        other assumptions set forth therein in accordance with its normal and
        customary procedures for evaluating oil and gas reserves and other
        related assets as such exist at that particular time. Administrative
        Agent shall propose to the Lenders a new Borrowing Base and Monthly
        Reduction Amount within 15 days following receipt by Administrative
        Agent and the

                                       20

<PAGE>

        Lenders of the Engineering Reports in a timely and complete manner.
        After having received notice of such proposal by Administrative Agent,
        the Lenders shall have 15 days to agree or disagree with such proposal.
        If at the end of the 15 days, the Lenders have not communicated their
        approval or disapproval, such silence shall be deemed to be an approval
        and Administrative Agent's proposal shall be the new Borrowing Base and
        Monthly Reduction Amount. If however, the Lenders notify Administrative
        Agent within 15 days of their disapproval, the Lenders shall, within a
        reasonable period of time, agree on a new Borrowing Base and Monthly
        Reduction Amount. Administrative Agent and all of the Lenders must
        approve any increase in the Borrowing Base and any decrease in the
        Monthly Reduction Amount, and Administrative Agent and Majority Lenders
        must approve any reaffirmation of or decrease in the Borrowing Base and
        any reaffirmation of or increase in the Monthly Reduction Amount.

                (c)     Excluded Property. Administrative Agent may exclude any
        Oil and Gas Property or portion of production therefrom or any income
        from any other Property from the Borrowing Base, at any time, because
        title information is not reasonably satisfactory, such Property is not
        Collateral or such Property is not assignable.

                (d)     Redeterminations. So long as any of the Commitments are
        in effect and until payment in full of all Loans hereunder, on or around
        the first Business Day of each June and December, commencing June, 2007
        (each being a "Scheduled Redetermination Date"), the Lenders shall
        redetermine the amount of the Borrowing Base and the Monthly Reduction
        Amount in accordance with Section 2.08(b).

                (e)     Unscheduled Redeterminations. In addition to the
        redeterminations of the Borrowing Base and the Monthly Reduction Amount
        described in Section 2.08(d), (i) Borrower may initiate a
        redetermination of the Borrowing Base and/or the Monthly Reduction
        Amount at any other time as it so elects by specifying in writing to
        Administrative Agent (who will promptly notify the Lenders) the date by
        which Borrower will furnish to Administrative Agent and the Lenders a
        Reserve Report in accordance with Section 8.07(b) and the date by which
        such redetermination is requested to occur; provided, however, that
        Borrower may initiate only one such unscheduled redetermination between
        Scheduled Redetermination Dates, (ii) the Majority Lenders or
        Administrative Agent may initiate a redetermination of the Borrowing
        Base and/or the Monthly Reduction Amount at any other time as they so
        elect by specifying in writing to Borrower the date by which Borrower is
        to furnish a Reserve Report in accordance with Section 8.07(b) and the
        date on which such redetermination is to occur; provided, however, that
        the Majority Lenders or Administrative Agent may initiate only one such
        unscheduled redetermination between Scheduled Redetermination Dates, and
        (iii) Administrative Agent may initiate a redetermination of the
        Borrowing Base and/or the Monthly Reduction Amount upon the occurrence
        of (A) an early termination or a material amendment or modification of
        the Aspen Operations Agreement or (B) the transfer of any interest in
        any Oil and Gas Properties of Borrower to Sigma pursuant to the terms of
        the Sigma Consulting Agreement.

                (f)     Redetermination Concurrent with Transfer. To the extent
        allowed by Section 9.12, if Borrower Transfers any Property between
        Scheduled Redetermination Dates with an aggregate fair market value in
        excess of $500,000, the Borrowing Base shall automatically be reduced
        upon execution of such Transfer by an amount equal to the Borrowing Base
        values (as determined by the Majority Lenders in their reasonable
        discretion) attributed in the immediately preceding determination of the
        Borrowing Base to the Property which is the subject of such Transfer.

                (g)     Effective Upon Notice. Administrative Agent shall
        promptly notify in writing Borrower and the Lenders of the new Borrowing
        Base and/or Monthly Reduction Amount. Any

                                       21

<PAGE>

        redetermination of the Borrowing Base and/or Monthly Reduction Amount
        shall not be in effect until written notice is received by Borrower.

        Section 2.09    Assumption of Risks. Borrower assumes all risks of the
acts or omissions of any beneficiary of any Letter of Credit or any transferee
thereof with respect to its use of such Letter of Credit. Neither the Issuing
Bank (except in the case of gross negligence or willful misconduct on the part
of the Issuing Bank or any of its employees), its correspondents nor any Lender
shall be responsible for the validity, sufficiency or genuineness of
certificates or other documents or any endorsements thereon, even if such
certificates or other documents should in fact prove to be invalid,
insufficient, fraudulent or forged; for errors, omissions, interruptions or
delays in transmissions or delivery of any messages by mail, telex, or
otherwise, whether or not they be in code; for errors in translation or for
errors in interpretation of technical terms; the validity or sufficiency of any
instrument transferring or assigning or purporting to transfer or assign any
Letter of Credit or the rights or benefits thereunder or proceeds thereof, in
whole or in part, which may prove to be invalid or ineffective for any reason;
the failure of any beneficiary or any transferee of any Letter of Credit to
comply fully with conditions required in order to draw upon any Letter of
Credit; or for any other consequences arising from causes beyond the Issuing
Bank's control or the control of the Issuing Bank's correspondents. In addition,
neither the Issuing Bank, Administrative Agent nor any Lender shall be
responsible for any error, neglect, or default of any of the Issuing Bank's
correspondents; and none of the above shall affect, impair or prevent the
vesting of any of the Issuing Bank's, Administrative Agent's or any Lender's
rights or powers hereunder or under the Letter of Credit Agreements, all of
which rights shall be cumulative. The Issuing Bank and its correspondents may
accept certificates or other documents that appear on their face to be in order,
without responsibility for further investigation of any matter contained therein
regardless of any notice or information to the contrary. In furtherance and not
in limitation of the foregoing provisions, Borrower agrees that any action,
inaction or omission taken or not taken by the Issuing Bank or by any
correspondent for the Issuing Bank in good faith in connection with any Letter
of Credit, or any related drafts, certificates, documents or instruments, shall
be binding on Borrower and shall not put the Issuing Bank or its correspondents
under any resulting liability to Borrower.

        Section 2.10    Obligation to Reimburse and to Prepay.

                (a)     Reimbursement Obligations. If a disbursement by the
        Issuing Bank is made under any Letter of Credit, Borrower shall pay to
        Administrative Agent within two (2) Business Days after notice of any
        such disbursement is received by Borrower, the amount of each such
        disbursement made by the Issuing Bank under the Letter of Credit (if
        such payment is not sooner effected as may be required under this
        Section 2.10 or under other provisions of the Letter of Credit),
        together with interest on the amount disbursed from and including the
        date of disbursement until payment in full of such disbursed amount at a
        varying rate per annum equal to (i) the then applicable interest rate
        for Base Rate Loans through the second Business Day after notice of such
        disbursement is received by Borrower and (ii) thereafter, the Post
        Default Rate for Base Rate Loans (but in no event to exceed the Highest
        Lawful Rate) for the period from and including the third Business Day
        following the date of such disbursement to and including the date of
        repayment in full of such disbursed amount. The obligations of Borrower
        under this Agreement with respect to each Letter of Credit shall be
        absolute, unconditional and irrevocable and shall be paid or performed
        strictly in accordance with the terms of this Agreement under all
        circumstances whatsoever, including, without limitation, but only to the
        fullest extent permitted by applicable law, the following circumstances:
        (i) any lack of validity or enforceability of this Agreement, any Letter
        of Credit or any of the Security Instruments; (ii) any amendment or
        waiver of (including any default), or any consent to departure from this
        Agreement (except to the extent permitted by any amendment or waiver),
        any Letter of Credit or any of the Security Instruments; (iii) the
        existence of any claim, set-off, defense or other rights which Borrower
        may have at any time against the beneficiary of any Letter of Credit or
        any transferee of any Letter of Credit (or

                                       22

<PAGE>

        any Persons for whom any such beneficiary or any such transferee may be
        acting), the Issuing Bank, Administrative Agent, any Lender or any other
        Person, whether in connection with this Agreement, any Letter of Credit,
        the Security Instruments, the transactions contemplated hereby or any
        unrelated transaction; (iv) any statement, certificate, draft, notice or
        any other document presented under any Letter of Credit proves to have
        been forged, fraudulent, insufficient or invalid in any respect or any
        statement therein proves to have been untrue or inaccurate in any
        respect whatsoever; (v) payment by the Issuing Bank under any Letter of
        Credit against presentation of a draft or certificate which appears on
        its face to comply, but does not comply, with the terms of such Letter
        of Credit; and (vi) any other circumstance or happening whatsoever,
        whether or not similar to any of the foregoing.

                Notwithstanding anything in this Agreement to the contrary,
        Borrower will not be liable for payment or performance that results from
        the gross negligence or willful misconduct of the Issuing Bank, except
        where Borrower or any Subsidiary actually recovers the proceeds for
        itself or the Issuing Bank of any payment made by the Issuing Bank in
        connection with such gross negligence or willful misconduct.

                (b)     Cash Collateral for LC Exposure. In the event of the
        occurrence of any Event of Default, a payment or prepayment pursuant to
        Section 2.07(b) or the maturity of the Notes, whether by acceleration or
        otherwise, an amount equal to the LC Exposure (or the excess in the case
        of Section 2.07(b)) shall be deemed to be forthwith due and owing by
        Borrower to the Issuing Bank, Administrative Agent and the Lenders as of
        the date of any such occurrence; and Borrower's obligation to pay such
        amount shall be absolute and unconditional, without regard to whether
        any beneficiary of any such Letter of Credit has attempted to draw down
        all or a portion of such amount under the terms of a Letter of Credit,
        and, to the fullest extent permitted by applicable law, shall not be
        subject to any defense or be affected by a right of set-off,
        counterclaim or recoupment which Borrower may now or hereafter have
        against any such beneficiary, the Issuing Bank, Administrative Agent,
        the Lenders or any other Person for any reason whatsoever. Such payments
        shall be held by the Issuing Bank on behalf of the Lenders as cash
        collateral securing the LC Exposure in an account or accounts at the
        Principal Office; and Borrower hereby grants to and by its deposit with
        Administrative Agent grants to Administrative Agent a security interest
        in such cash collateral. In the event of any such payment by Borrower of
        amounts contingently owing under outstanding Letters of Credit and in
        the event that thereafter drafts or other demands for payment complying
        with the terms of such Letters of Credit are not made prior to the
        respective expiration dates thereof, Administrative Agent agrees, if no
        Event of Default has occurred and is continuing or if no other amounts
        are outstanding under this Agreement, the Notes or any other Loan
        Documents, to remit to Borrower amounts for which the contingent
        obligations evidenced by the Letters of Credit have ceased.

                (c)     Lender Reimbursement. Each Lender severally and
        unconditionally agrees that it shall promptly reimburse the Issuing Bank
        an amount equal to such Lender's Percentage Share of any disbursement
        made by the Issuing Bank under any Letter of Credit that is not
        reimbursed according to this Section 2.10.

                (d)     Automatic Funding as Loan. Notwithstanding anything to
        the contrary contained herein, if no Default exists or would result
        therefrom, to the extent Borrower has not reimbursed the Issuing Bank
        for any drawn upon Letter of Credit within two (2) Business Days after
        notice of such disbursement has been received by Borrower, the amount of
        such Letter of Credit reimbursement obligation shall automatically be
        funded by the Lenders as a Loan hereunder and used by the Lender to pay
        such Letter of Credit reimbursement obligation. If an Event of Default
        exists, such Letter of Credit reimbursement obligation shall not be
        funded as a Loan, but instead shall accrue interest as provided in
        Section 2.10(a).

        Section 2.11    Lending Offices. The Loans of each Type made by each
Lender shall be made and maintained at such Lender's Applicable Lending Office
for Loans of such Type.

                                   ARTICLE III

                       PAYMENTS OF PRINCIPAL AND INTEREST

        Section 3.01    Repayment of Loans.

                (a)     Loans. On the Revolving Credit Termination Date Borrower
        shall repay the outstanding aggregate principal amount of the Notes.

                (b)     Generally. Borrower will pay to Administrative Agent,
        for the account of each Lender, the principal payments required by this
        Section 3.01.

        Section 3.02    Interest.

                (a)     Interest Rates. Borrower will pay to Administrative
        Agent, for the account of each Lender, interest on the unpaid principal
        amount of each Loan made by such Lender for the period commencing on the
        date such Loan is made to, but excluding, the date such Loan shall be
        paid in full, at the following rates per annum:

                        (i)     if such a Loan is a Base Rate Loan, the Base
        Rate (as in effect from time to time) plus the Applicable Margin, but in
        no event to exceed the Highest Lawful Rate; and

                        (ii)    if such a Loan is a LIBOR Loan, for each
        Interest Period relating thereto, the LIBOR Adjusted Rate for such Loan
        plus the Applicable Margin (as in effect from time to time), but in no
        event to exceed the Highest Lawful Rate.

                (b)     Post Default Rate. Notwithstanding the foregoing,
        Borrower will pay to Administrative Agent, for the account of each
        Lender interest at the applicable Post Default Rate on any principal of
        any Loan made by such Lender, and (to the fullest extent permitted by
        law) on any other amount payable by Borrower hereunder, under any Loan
        Document or under any Note held by such Lender to or for account of such
        Lender, for the period commencing on the date of an Event of Default
        until the same is paid in full or all Events of Default are cured or
        waived.

                (c)     Due Dates. Accrued interest on Base Rate Loans shall be
        payable monthly on the [last Business Day of each month commencing on
        March 30, 2007], and accrued interest on each LIBOR Loan shall be
        payable on the last day of the Interest Period therefor and, if such
        Interest Period is longer than three months at three-month intervals
        following the first day of such Interest Period, except that interest
        payable at the Post Default Rate shall be payable from time to time on
        demand and interest on any LIBOR Loan that is converted into a Base Rate
        Loan (pursuant to Section 5.04) shall be payable on the date of
        conversion (but only to the extent so converted). Any accrued and unpaid
        interest on the Loans on the Revolving Credit Termination Date shall be
        paid on such date.

                (d)     Determination of Rates. Promptly after the determination
        of any interest rate provided for herein or any change therein,
        Administrative Agent shall notify the Lenders to which such interest is
        payable and Borrower thereof. Each determination by Administrative Agent
        of an interest rate or fee hereunder shall, except in cases of manifest
        error, be final, conclusive and binding on the parties.

                PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

        Section 4.01    Payments. Except to the extent otherwise provided
herein, all payments of principal, interest and other amounts to be made by
Borrower under this Agreement, the Notes, the Letter of Credit Agreements or any
other Loan Document shall be made in Dollars, in immediately available funds, to
Administrative Agent at such account as Administrative Agent shall specify by
notice to Borrower from time to time, not later than 11:00 a.m. Houston, Texas
time on the date on which such payments shall become due (each such payment made
after such time on such due date to be deemed to have been made on the next
succeeding Business Day). Such payments shall be made without (to the fullest
extent permitted by applicable law) defense, set-off or counterclaim and in
connection therewith, Borrower and each Guarantor hereby waives (to the fullest
extent permitted by applicable law) all defenses, rights of set-off and
counterclaims it may have with respect to such payments. Each payment received
by Administrative Agent under this Agreement or any Note for account of a Lender
shall be paid promptly to such Lender in immediately available funds. Except as
otherwise provided in the definition of "Interest Period", if the due date of
any payment under this Agreement or any Note would otherwise fall on a day which
is not a Business Day such date shall be extended to the next succeeding
Business Day and interest shall be payable for any principal so extended for the
period of such extension. At the time of each payment to Administrative Agent of
any principal of or interest on any borrowing, Borrower shall notify
Administrative Agent of the Loans to which such payment shall apply. In the
absence of such notice Administrative Agent may specify the Loans to which such
payment shall apply, but to the extent possible such payment or prepayment will
be applied first to the Loans comprised of Base Rate Loans.

        Section 4.02    Pro Rata Treatment. Except to the extent otherwise
provided herein each Lender agrees that: (i) each borrowing from the Lenders
under Section 2.01 and each continuation and conversion under Section 2.02 shall
be made from the Lenders pro rata in accordance with their Percentage Share,
each payment of fees under Section 2.04(a) and Section 2.04(b)(i) shall be made
for account of the Lenders pro rata in accordance with their Percentage Share,
and each termination or reduction of the amount of the Aggregate Maximum
Revolving Credit Amounts under Section 2.03(b) shall be applied to the
Commitment of each Lender, pro rata according to the amounts of its respective
Commitment; (ii) each payment of principal of Loans by Borrower shall be made
for account of the Lenders pro rata in accordance with the respective unpaid
principal amount of the Loans held by the Lenders; (iii) each payment of
interest on Loans by Borrower shall be made for account of the Lenders pro rata
in accordance with the amounts of interest due and payable to the respective
Lenders; and (iv) each reimbursement by Borrower of disbursements under Letters
of Credit shall be made for account of the Issuing Bank or, if funded by the
Lenders, pro rata for the account of the Lenders, in accordance with the amounts
of reimbursement obligations due and payable to each respective Lender.

        Section 4.03    Computations. Interest on LIBOR Loans and fees shall be
computed on the basis of a year of 360 days and actual days elapsed (including
the first day but excluding the last day) occurring in the period for which such
interest is payable, unless such calculation would exceed the Highest Lawful
Rate, in which case interest shall be calculated on the per annum basis of a
year of 365 or 366 days, as the case may be. Interest on Base Rate Loans shall
be computed on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed (including the first day but excluding the last day)
occurring in the period for which such interest is payable.

        Section 4.04    Non-receipt of Funds by Administrative Agent. Unless
Administrative Agent shall have been notified by a Lender or Borrower prior to
the date on which such notifying party is scheduled to make payment to
Administrative Agent (in the case of a Lender) of the proceeds of a Loan or a
payment under a Letter of Credit to be made by it hereunder or (in the case of
Borrower) a payment to Administrative Agent for account of one or more of the
Lenders hereunder (such payment being herein

                                       25

<PAGE>

called the "Required Payment"), which notice shall be effective upon receipt,
that it does not intend to make the Required Payment to Administrative Agent,
Administrative Agent may assume that the Required Payment has been made and may,
in reliance upon such assumption (but shall not be required to), make the amount
thereof available to the intended recipient(s) on such date and, if such Lender
or Borrower (as the case may be) has not in fact made the Required Payment to
Administrative Agent, the recipient(s) of such payment shall, on demand, repay
to Administrative Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by Administrative Agent until, but excluding, the
date Administrative Agent recovers such amount at a rate per annum which, for
any Lender as recipient, will be equal to the Federal Funds Rate, and for
Borrower as recipient, will be equal to the Base Rate plus the Applicable
Margin.

        Section 4.05    Set-off, Sharing of Payments, Etc.

                (a)     Borrower agrees that, in addition to (and without
        limitation of) any right of set-off, bankers' lien or counterclaim a
        Lender may otherwise have, each Lender shall have the right and be
        entitled (after consultation with Administrative Agent), at its option,
        to offset balances held by it or by any of its Affiliates for account of
        Borrower or any Subsidiary at any of its offices, in Dollars or in any
        other currency, against any principal of or interest on any of such
        Lender's Loans, or any other amount payable to such Lender hereunder,
        which is not paid when due (regardless of whether such balances are then
        due to Borrower), in which case it shall promptly notify Borrower and
        Administrative Agent thereof, provided that such Lender's failure to
        give such notice shall not affect the validity thereof.

                (b)     If any Lender shall obtain payment of any principal of
        or interest on any Loan made by it to Borrower under this Agreement (or
        reimbursement as to any Letter of Credit) through the exercise of any
        right of set-off, banker's lien or counterclaim or similar right or
        otherwise, and, as a result of such payment, such Lender shall have
        received a greater percentage of the principal or interest (or
        reimbursement) then due hereunder by Borrower to such Lender than the
        percentage received by any other Lenders, it shall promptly (i) notify
        Administrative Agent and each other Lender thereof and (ii) purchase
        from such other Lenders participation in (or, if and to the extent
        specified by such Lender, direct interests in) the Loans (or
        participations in Letters of Credit) made by such other Lenders (or in
        interest due thereon, as the case may be) in such amounts, and make such
        other adjustments from time to time as shall be equitable, to the end
        that all the Lenders shall share the benefit of such excess payment (net
        of any expenses which may be incurred by such Lender in obtaining or
        preserving such excess payment) pro rata in accordance with the unpaid
        principal and/or interest on the Loans held by each of the Lenders (or
        reimbursements of Letters of Credit). To such end all the Lenders shall
        make appropriate adjustments among themselves (by the resale of
        participations sold or otherwise) if such payment is rescinded or must
        otherwise be restored. Borrower agrees that any Lender so purchasing a
        participation (or direct interest) in the Loans made by other Lenders
        (or in interest due thereon, as the case may be) may exercise all rights
        of set-off, banker's lien, counterclaim or similar rights with respect
        to such participation as fully as if such Lender were a direct holder of
        Loans (or Letters of Credit) in the amount of such participation.
        Nothing contained herein shall require any Lender to exercise any such
        right or shall affect the right of any Lender to exercise, and retain
        the benefits of exercising, any such right with respect to any other
        indebtedness or obligation of Borrower. If under any applicable
        bankruptcy, insolvency or other similar law, any Lender receives a
        secured claim in lieu of a set-off to which this Section 4.05 applies,
        such Lender shall, to the extent practicable, exercise its rights in
        respect of such secured claim in a manner consistent with the rights of
        the Lenders entitled under this Section 4.05 to share the benefits of
        any recovery on such secured claim.

        Section 4.06    Taxes.

                (a)     Payments Free and Clear. Any and all payments by
        Borrower hereunder shall be made, in accordance with Section 4.01, free
        and clear of and without deduction for any and all present or future
        taxes, levies, imposts, deductions, charges or withholdings, and all
        liabilities with respect thereto, excluding, in the case of each Lender,
        the Issuing Bank and Administrative Agent, taxes imposed on its income,
        and franchise or similar taxes imposed on it, by (i) any jurisdiction
        (or political subdivision thereof) of which Administrative Agent, the
        Issuing Bank or such Lender, as the case may be, is a citizen or
        resident or in which such Lender has an Applicable Lending Office, (ii)
        the jurisdiction (or any political subdivision thereof) in which
        Administrative Agent, the Issuing Bank or such Lender is organized, or
        (iii) any jurisdiction (or political subdivision thereof) in which such
        Lender, the Issuing Bank or Administrative Agent is presently doing
        business which taxes are imposed solely as a result of doing business in
        such jurisdiction (all such non-excluded taxes, levies, imposts,
        deductions, charges, withholdings and liabilities being hereinafter
        referred to as "Taxes"). If Borrower shall be required by law to deduct
        any Taxes from or in respect of any sum payable hereunder to the
        Lenders, the Issuing Bank or Administrative Agent (i) the sum payable
        shall be increased by the amount necessary so that after making all
        required deductions (including deductions applicable to additional sums
        payable under this Section 4.06) such Lender, the Issuing Bank or
        Administrative Agent (as the case may be) shall receive an amount equal
        to the sum it would have received had no such deductions been made, (ii)
        Borrower shall make such deductions and (iii) Borrower shall pay the
        full amount deducted to the relevant taxing authority or other
        Governmental Authority in accordance with applicable law.

                (b)     Other Taxes. In addition, to the fullest extent
        permitted by applicable law, Borrower agrees to pay any present or
        future stamp or documentary taxes or any other excise or property taxes,
        charges or similar levies that arise from any payment made hereunder or
        from the execution, delivery or registration of, or otherwise with
        respect to, this Agreement, any Assignment or any other Loan Document
        (hereinafter referred to as "Other Taxes").

                (C)     INDEMNIFICATION. TO THE FULLEST EXTENT PERMITTED BY
        APPLICABLE LAW, BORROWER WILL INDEMNIFY EACH LENDER AND THE ISSUING BANK
        AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES AND OTHER
        TAXES (INCLUDING, BUT NOT LIMITED TO, ANY TAXES OR OTHER TAXES IMPOSED
        BY ANY GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION
        4.06) PAID BY SUCH LENDER, THE ISSUING BANK OR ADMINISTRATIVE AGENT (ON
        THEIR BEHALF OR ON BEHALF OF ANY LENDER), AS THE CASE MAY BE, AND ANY
        LIABILITY (INCLUDING PENALTIES, INTEREST AND EXPENSES) ARISING THEREFROM
        OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE
        CORRECTLY OR LEGALLY ASSERTED UNLESS THE PAYMENT OF SUCH TAXES WAS NOT
        CORRECTLY OR LEGALLY ASSERTED AND SUCH LENDER'S PAYMENT OF SUCH TAXES OR
        OTHER TAXES WAS THE RESULT OF ITS GROSS NEGLIGENCE OR WILLFUL
        MISCONDUCT. ANY PAYMENT PURSUANT TO SUCH INDEMNIFICATION SHALL BE MADE
        WITHIN THIRTY (30) DAYS AFTER THE DATE ANY LENDER, THE ISSUING BANK OR
        ADMINISTRATIVE AGENT, AS THE CASE MAY BE, MAKES WRITTEN DEMAND THEREFOR.
        IF ANY LENDER, THE ISSUING BANK OR ADMINISTRATIVE AGENT RECEIVES A
        REFUND OR CREDIT IN RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH SUCH
        LENDER, ISSUING BANK OR ADMINISTRATIVE AGENT HAS RECEIVED PAYMENT FROM
        BORROWER IT SHALL PROMPTLY NOTIFY BORROWER OF SUCH REFUND OR CREDIT AND
        SHALL, IF NO DEFAULT HAS OCCURRED AND IS CONTINUING, WITHIN THIRTY (30)
        DAYS AFTER RECEIPT OF A REQUEST BY BORROWER (OR PROMPTLY UPON RECEIPT,
        IF BORROWER HAS REQUESTED APPLICATION FOR SUCH REFUND OR CREDIT PURSUANT
        HERETO), PAY AN AMOUNT EQUAL TO SUCH REFUND OR CREDIT TO BORROWER
        WITHOUT INTEREST (BUT WITH ANY INTEREST SO

                                       27

<PAGE>

        REFUNDED OR CREDITED), PROVIDED THAT BORROWER, UPON THE REQUEST OF SUCH
        LENDER, THE ISSUING BANK OR ADMINISTRATIVE AGENT, AGREES TO RETURN SUCH
        REFUND OR CREDIT (PLUS PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH
        LENDER OR ADMINISTRATIVE AGENT IN THE EVENT SUCH LENDER OR
        ADMINISTRATIVE AGENT IS REQUIRED TO REPAY SUCH REFUND OR CREDIT.

                (d)     Lender Representations.

                        (i)     Each Lender represents that it is either (1) a
        banking association or corporation organized under the laws of the
        United States of America or any state thereof or (2) it is entitled to
        complete exemption from United States withholding tax imposed on or with
        respect to any payments, including fees, to be made to it pursuant to
        this Agreement (A) under an applicable provision of a tax convention to
        which the United States of America is a party or (B) because it is
        acting through a branch, agency or office in the United States of
        America and any payment to be received by it hereunder is effectively
        connected with a trade or business in the United States of America. Each
        Lender that is not a banking association or corporation organized under
        the laws of the United States of America or any state thereof agrees to
        provide to Borrower and Administrative Agent on the Closing Date, or on
        the date of its delivery of the Assignment pursuant to which it becomes
        a Lender, and at such other times as required by United States law or as
        Borrower or Administrative Agent shall reasonably request, two accurate
        and complete original signed copies of either (A) Internal Revenue
        Service Form W-8ECI (or successor form) certifying that all payments to
        be made to it hereunder will be effectively connected to a United States
        trade or business (the "Form W-8ECI Certification") or (B) Internal
        Revenue Service Form W-8BEN (or successor form) certifying that it is
        entitled to the benefit of a provision of a tax convention to which the
        United States of America is a party which completely exempts from United
        States withholding tax all payments to be made to it hereunder (the
        "Form W-8BEN Certification"). In addition, each Lender agrees that if it
        previously filed a Form W-8ECI Certification, it will deliver to
        Borrower and Administrative Agent a new Form W-8ECI Certification prior
        to the first payment date occurring in each of its subsequent taxable
        years; and if it previously filed a Form W-8BEN Certification, it will
        deliver to Borrower and Administrative Agent a new certification prior
        to the first payment date falling in the third year following the
        previous filing of such certification. Each Lender also agrees to
        deliver to Borrower and Administrative Agent such other or supplemental
        forms as may at any time be required as a result of changes in
        applicable law or regulation in order to confirm or maintain in effect
        its entitlement to exemption from United States withholding tax on any
        payments hereunder, provided that the circumstances of such Lender at
        the relevant time and applicable laws permit it to do so. If a Lender
        determines, as a result of any change in either (i) a Governmental
        Requirement or (ii) its circumstances, that it is unable to submit any
        form or certificate that it is obligated to submit pursuant to this
        Section 4.06, or that it is required to withdraw or cancel any such form
        or certificate previously submitted, it shall promptly notify Borrower
        and Administrative Agent of such fact. If a Lender is organized under
        the laws of a jurisdiction outside the United States of America, unless
        Borrower and Administrative Agent have received a Form W-8BEN
        Certification or Form W-8ECI Certification satisfactory to them
        indicating that all payments to be made to such Lender hereunder are not
        subject to United States withholding tax, Borrower shall withhold taxes
        from such payments at the applicable statutory rate. Each Lender agrees
        to indemnify and hold harmless Borrower or Administrative Agent, as
        applicable, from any United States taxes, penalties, interest and other
        expenses, costs and losses incurred or payable by (i) Administrative
        Agent as a result of such Lender's failure to submit any form or
        certificate that it is required to provide pursuant to this Section 4.06
        or (ii) Borrower or Administrative Agent as a result of their reliance
        on any such form or certificate which such Lender has provided to them
        pursuant to this Section 4.06.

                                       28

<PAGE>

                        (ii)    For any period with respect to which a Lender
        has failed to provide Borrower with the form required pursuant to this
        Section 4.06, if any, (other than if such failure is due to a change in
        a Governmental Requirement occurring subsequent to the date on which a
        form originally was required to be provided), such Lender shall not be
        entitled to indemnification under Section 4.06 with respect to taxes
        imposed by the United States which taxes would not have been imposed but
        for such failure to provide such forms; provided, however, that if a
        Lender, which is otherwise exempt from or subject to a reduced rate of
        withholding tax, becomes subject to taxes because of its failure to
        deliver a form required hereunder, Borrower shall take such steps as
        such Lender shall reasonably request to assist such Lender to recover
        such taxes.

                        (iii)   Any Lender claiming any additional amounts
        payable pursuant to this Section 4.06 shall use reasonable efforts
        (consistent with legal and regulatory restrictions) to file any
        certificate or document requested by Borrower or Administrative Agent or
        to change the jurisdiction of its Applicable Lending Office or to
        contest any tax imposed if the making of such a filing or change or
        contesting such tax would avoid the need for or reduce the amount of any
        such additional amounts that may thereafter accrue and would not, in the
        sole determination of such Lender, be otherwise disadvantageous to such
        Lender.

        Section 4.07    Disposition of Proceeds. Some of the Security
Instruments contain an assignment by Borrower unto and in favor of
Administrative Agent for the benefit of the Lenders of all production and all
proceeds attributable thereto which may be produced from or allocated to Oil and
Gas Properties, and such Security Instruments further provide in general for the
application of such proceeds to the satisfaction of the Obligations and other
indebtedness, liabilities and obligations described therein and secured thereby.
Notwithstanding the assignment contained in such Security Instruments, until the
occurrence of an Event of Default, the Lenders agree that they will neither
notify the Purchasers of such production nor take any other action to cause such
proceeds to be remitted to the Lenders, but the Lenders will instead permit such
proceeds to be paid to Borrower.

                                   ARTICLE V

                      CAPITAL ADEQUACY AND ADDITIONAL COSTS

        Section 5.01    Additional Costs.

                (a)     LIBOR Regulations, etc. Borrower shall pay directly to
        each Lender from time to time such amounts as such Lender may determine
        to be necessary to compensate such Lender for any costs which it
        determines are attributable to its making or maintaining of any LIBOR
        Loans or issuing or participating in Letters of Credit hereunder or its
        obligation to make any LIBOR Loans or issue or participate in any
        Letters of Credit hereunder, or any reduction in any amount receivable
        by such Lender hereunder in respect of any of such LIBOR Loans, Letters
        of Credit or such obligation (such increases in costs and reductions in
        amounts receivable being herein called "Additional Costs"), resulting
        from any Regulatory Change which: (i) changes the basis of taxation of
        any amounts payable to such Lender under this Agreement or any Note in
        respect of any of such LIBOR Loans or Letters of Credit (other than
        taxes imposed on the overall net income of such Lender or of its
        Applicable Lending Office for any of such LIBOR Loans by the
        jurisdiction in which such Lender has its principal office or Applicable
        Lending Office); or (ii) imposes or modifies any reserve, special
        deposit, minimum capital, capital ratio or similar requirements relating
        to any extensions of credit or other assets of, or any deposits with or
        other liabilities of such Lender, or the Commitment or Loans of such
        Lender or the London interbank market; or (iii) imposes any other
        condition affecting this Agreement or any Note (or any of such
        extensions of credit or liabilities) or such Lender's Commitment or
        Loans. Each Lender will notify Administrative Agent and Borrower of any
        event occurring after the Closing Date which

                                       29

<PAGE>

        will entitle such Lender to compensation pursuant to this Section
        5.01(a) as promptly as practicable after it obtains knowledge thereof
        and determines to request such compensation, and will designate a
        different Applicable Lending Office for the Loans of such Lender
        affected by such event if such designation will avoid the need for, or
        reduce the amount of, such compensation and will not, in the sole
        opinion of such Lender, be disadvantageous to such Lender, provided that
        such Lender shall have no obligation to so designate an Applicable
        Lending Office located in the United States. If any Lender requests
        compensation from Borrower under this Section 5.01(a), Borrower may, by
        notice to such Lender, suspend the obligation of such Lender to make
        additional Loans of the Type with respect to which such compensation is
        requested until the Regulatory Change giving rise to such request ceases
        to be in effect (in which case the provisions of Section 5.04 shall be
        applicable).

                (b)     Regulatory Change. Without limiting the effect of the
        provisions of Section 5.01(a), in the event that at any time (by reason
        of any Regulatory Change or any other circumstances arising after the
        Closing Date affecting (A) any Lender, (B) the London interbank market
        or (C) such Lender's position in such market), the LIBOR Adjusted Rate,
        as determined in good faith by such Lender, will not adequately and
        fairly reflect the cost to such Lender of funding its LIBOR Loans, then,
        if such Lender so elects, by notice to Borrower and Administrative
        Agent, the obligation of such Lender to make additional LIBOR Loans
        shall be suspended until such Regulatory Change or other circumstances
        ceases to be in effect (in which case the provisions of Section 5.04
        shall be applicable).

                (c)     Capital Adequacy. Without limiting the effect of the
        foregoing provisions of this Section 5.01 (but without duplication),
        Borrower shall pay directly to any Lender from time to time on request
        such amounts as such Lender may reasonably determine to be necessary to
        compensate such Lender or its parent or holding company for any costs
        which it determines are attributable to the maintenance by such Lender
        or its parent or holding company (or any Applicable Lending Office),
        pursuant to any Governmental Requirement following any Regulatory
        Change, of capital in respect of its Commitment, its Note, its Loans or
        any interest held by it in any Letter of Credit, such compensation to
        include, without limitation, an amount equal to any reduction of the
        rate of return on assets or equity of such Lender or its parent or
        holding company (or any Applicable Lending Office) to a level below that
        which such Lender or its parent or holding company (or any Applicable
        Lending Office) could have achieved but for such Governmental
        Requirement. Such Lender will notify Borrower that it is entitled to
        compensation pursuant to this Section 5.01(c) as promptly as practicable
        after it determines to request such compensation.

                (d)     Compensation Procedure. Any Lender notifying Borrower of
        the incurrence of Additional Costs under this Section 5.01 shall in such
        notice to Borrower and Administrative Agent set forth in reasonable
        detail the basis and amount of its request for compensation.
        Determinations and allocations by each Lender for purposes of this
        Section 5.01 of the effect of any Regulatory Change pursuant to Section
        5.01(a) or (b), or of the effect of capital maintained pursuant to
        Section 5.01(c), on its costs or rate of return of maintaining Loans or
        its obligation to make Loans or issue Letters of Credit, or on amounts
        receivable by it in respect of Loans or Letters of Credit, and of the
        amounts required to compensate such Lender under this Section 5.01,
        shall be conclusive and binding for all purposes, provided that such
        determinations and allocations are made on a reasonable basis. Any
        request for additional compensation under this Section 5.01 shall be
        paid by Borrower within thirty (30) days of the receipt by Borrower of
        the notice described in this Section 5.01(d).

        Section 5.02    Limitation on LIBOR Loans. Anything herein to the
contrary notwithstanding, if, on or prior to the determination of any LIBOR
Adjusted Rate for any Interest Period:

<PAGE>

                        (i)     Administrative Agent determines (which
        determination shall be conclusive, absent manifest error) that
        quotations of interest rates for the relevant deposits referred to in
        the definition of "LIBOR Adjusted Rate" in Section 1.02 are not being
        provided in the relevant amounts or for the relevant maturities for
        purposes of determining rates of interest for LIBOR Loans as provided
        herein; or

                        (ii)    Administrative Agent determines (which
        determination shall be conclusive, absent manifest error) that the
        relevant rates of interest referred to in the definition of "LIBOR
        Adjusted Rate" in Section 1.02 upon the basis of which the rate of
        interest for LIBOR Loans for such Interest Period is to be determined
        are not sufficient to adequately cover the cost to the Lenders of making
        or maintaining LIBOR Loans;

then Administrative Agent shall give Borrower prompt notice thereof, and so long
as such condition remains in effect, the Lenders shall be under no obligation to
make additional LIBOR Loans.

        Section 5.03    Illegality. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain LIBOR
Loans hereunder, then such Lender shall promptly notify Borrower thereof and
such Lender's obligation to make LIBOR Loans shall be suspended until such time
as such Lender may again make and maintain LIBOR Loans (in which case the
provisions of Section 5.04 shall be applicable).

        Section 5.04    Base Rate Loans Pursuant to Sections 5.01, 5.02 and
5.03. If the obligation of any Lender to make LIBOR Loans shall be suspended
pursuant to Sections 5.01, 5.02 or 5.03 ("Affected Loans"), all Affected Loans
which would otherwise be made by such Lender shall be made instead as Base Rate
Loans (and, if an event referred to in Section 5.01(b) or Section 5.03 has
occurred and such Lender so requests by notice to Borrower, all Affected Loans
of such Lender then outstanding shall be automatically converted into Base Rate
Loans on the date specified by such Lender in such notice) and, to the extent
that Affected Loans are so made as (or converted into) Base Rate Loans, all
payments of principal which would otherwise be applied to such Lender's Affected
Loans shall be applied instead to its Base Rate Loans.

        Section 5.05    Compensation. Borrower shall pay to each Lender within
thirty (30) days of receipt of written request of such Lender (which request
shall set forth, in reasonable detail, the basis for requesting such amounts and
which shall be conclusive and binding for all purposes provided that such
determinations are made on a reasonable basis), such amount or amounts as shall
compensate it for any loss, cost, expense or liability which such Lender
determines are attributable to:

                        (i)     any payment, prepayment or conversion of a LIBOR
        Loan properly made by such Lender or Borrower for any reason (including,
        without limitation, the acceleration of the Loans pursuant to Section
        10.01) on a date other than the last day of the Interest Period for such
        Loan; or

                        (ii)    any failure by Borrower for any reason
        (including but not limited to, the failure of any of the conditions
        precedent specified in Article VI to be satisfied) to borrow, continue
        or convert a LIBOR Loan from such Lender on the date for such borrowing,
        continuation or conversion specified in the relevant notice given
        pursuant to Section 2.02(c).

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
which would have accrued on the principal amount so paid, prepaid or converted
or not borrowed for the period from the date of such payment, prepayment or
conversion or failure to borrow to the last day of the Interest Period for such
Loan (or, in the case of a failure to borrow, the Interest Period for such Loan
which would have commenced on the date specified

                                       31

<PAGE>

for such borrowing) at the applicable rate of interest for such Loan provided
for herein over (ii) the interest component of the amount such Lender would have
bid in the London interbank market for Dollar deposits of leading banks in
amounts comparable to such principal amount and with maturities comparable to
such period (as reasonably determined by such Lender).

                                   ARTICLE VI

        Section 6.02    Initial and Subsequent Loans and Letters of Credit. The
obligation of the Lenders to make Loans to Borrower upon the occasion of each
borrowing hereunder and to issue, renew, extend or reissue Letters of Credit for
the account of Borrower (including the Initial Funding) is subject to the
further conditions precedent that, as of the date of such Loans and after giving
effect thereto:

                (a)     no Default shall exist;

                (b)     no Material Adverse Effect shall have occurred; and

                (c)     the representations and warranties made by Borrower in
        Article VII and by Borrower and Guarantors in the other Loan Documents
        to which they are a party shall be true on and as of the date of the
        making of such Loans or issuance, renewal, extension or reissuance of a
        Letter of Credit with the same force and effect as if made on and as of
        such date and following such new borrowing, except to the extent such
        representations and warranties are expressly limited to an earlier date
        or the Majority Lenders may expressly consent in writing to the
        contrary.

        Each request for a borrowing or issuance, renewal, extension or
reissuance of a Letter of Credit by Borrower hereunder shall constitute a
certification by Borrower that the statements set forth in Section 6.02(a), (b)
and (c) are true (both as of the date of such notice and, unless Borrower
otherwise notifies Administrative Agent prior to the date of and immediately
following such borrowing or issuance, renewal, extension or reissuance of a
Letter of Credit, as of the date thereof).

        Section 6.03    Conditions Precedent for the Benefit of Lenders. All
conditions precedent to the obligations of the Lenders to make any Loan are
imposed hereby solely for the benefit of the Lenders, and no other Person may
require satisfaction of any such condition precedent or be entitled to assume
that the Lenders will refuse to make any Loan in the absence of strict
compliance with such conditions precedent.

        Section 6.04    No Waiver. No waiver of any condition precedent shall
preclude Administrative Agent or the Lenders from requiring such condition to be
met prior to making any subsequent Loan or preclude the Lenders from thereafter
declaring that the failure of Borrower to satisfy such condition precedent
constitutes a Default.

                                  ARTICLE VII

                         REPRESENTATIONS AND WARRANTIES

        Borrower represents and warrants to Administrative Agent and the Lenders
that (each representation and warranty herein is given as of the Closing Date
and shall be deemed repeated and

                                       34

<PAGE>

reaffirmed on the dates of each borrowing and issuance, renewal, extension or
reissuance of a Letter of Credit as provided in Section 6.02):

        Section 7.01    Corporate Existence. Each of Borrower and each
Subsidiary: (i) is duly organized, validly existing and in good standing under
the laws of the jurisdiction of its formation; (ii) has all requisite entity
power, and has all material governmental licenses, authorizations, consents and
approvals necessary to own its assets and carry on its business as now being or
as proposed to be conducted; and (iii) is qualified to do business in all
jurisdictions in which the nature of the business conducted by it makes such
qualification necessary and where failure so to qualify would have a Material
Adverse Effect.

        Section 7.02    Financial Condition. The audited consolidated balance
sheet of Parent and its Consolidated Subsidiaries as at December 31, 2005 and
the related consolidated statement of income, stockholders' equity and cash flow
of Parent and its Consolidated Subsidiaries for the fiscal year ended on said
date, with the opinion thereon of Malone & Bailey, P.C. heretofore furnished to
each of the Lenders and the unaudited consolidated balance sheet of Parent and
its Consolidated Subsidiaries as at September 30, 2006 and their related
consolidated statements of income, stockholders' equity and cash flow of Parent
and its Consolidated Subsidiaries for the nine month period ended on such date
heretofore furnished to Administrative Agent, are complete and correct and
fairly present in all material respects the consolidated financial condition of
Borrower and its Consolidated Subsidiaries as at said dates and the results of
its operations for the fiscal year and the nine month period on said dates, all
in accordance with GAAP, as applied on a consistent basis (subject, in the case
of the interim financial statements, to normal year-end adjustments). Neither
Borrower nor any Subsidiary has on the Closing Date any material Debt,
contingent liabilities, liabilities for taxes, unusual forward or long-term
commitments or unrealized or anticipated losses from any unfavorable
commitments, except as referred to or reflected or provided for in Schedule
7.02. Since the date of formation of Borrower, there has been no change or event
having a Material Adverse Effect. Since the date of formation of Borrower,
neither the business nor the Properties of Borrower or any Subsidiary have been
materially and adversely affected as a result of any fire, explosion,
earthquake, flood, drought, windstorm, accident, strike or other labor
disturbance, embargo, requisition or taking of Property or cancellation of
contracts, permits or concessions by any Governmental Authority, riot,
activities of armed forces or acts of God or of any public enemy.

        Section 7.03    Litigation. Except as disclosed to the Lenders in
Schedule 7.03 hereto, at the Closing Date there is no litigation, legal,
administrative or arbitral proceeding, investigation or other action of any
nature pending or, to the knowledge of Borrower threatened against or affecting
Borrower or any Subsidiary which involves the possibility of any judgment or
liability against Borrower or any Subsidiary not fully covered by insurance
(except for normal deductibles).

        Section 7.04    No Breach. Neither the execution and delivery of the
Loan Documents, nor compliance with the terms and provisions hereof will
conflict with or result in a breach of, or require any consent which has not
been obtained as of the Closing Date under, the respective charter or by-laws of
Borrower or any Subsidiary, or any Governmental Requirement or any agreement or
instrument to which Borrower or any Subsidiary is a party or by which it is
bound or to which it or its Properties are subject, or constitute a default
under any such agreement or instrument, or result in the creation or imposition
of any Lien upon any of the revenues or assets of Borrower or any Subsidiary
pursuant to the terms of any such agreement or instrument other than the Liens
created by the Loan Documents.

        Section 7.05    Authority. Borrower and each Subsidiary have all
necessary corporate power and authority to execute, deliver and perform its
obligations under the Loan Documents to which it is a party; and the execution,
delivery and performance by Borrower and each Subsidiary of the Loan Documents
to which it is a party, have been duly authorized by all necessary corporate
action on its part;

                                       35

<PAGE>

and the Loan Documents constitute the legal, valid and binding obligations of
Borrower and each Subsidiary, enforceable in accordance with their terms.

        Section 7.06    Approvals. No authorizations, approvals or consents of,
and no filings or registrations with, any Governmental Authority are necessary
for the execution, delivery or performance by Borrower or any Subsidiary of the
Loan Documents or for the validity or enforceability thereof, except for the
recording and filing of the Security Instruments as required by this Agreement.

        Section 7.07    Use of Loans. The proceeds of the Loans shall be used
(i) to acquire Oil and Gas Properties from Five States Energy Company, L.L.C.
and (ii) for working capital and general business purposes of Borrower and its
Subsidiaries. Borrower is not engaged principally, or as one of its important
activities, in the business of extending credit for the purpose, whether
immediate, incidental or ultimate, of buying or carrying margin stock (within
the meaning of Regulation T, U or X of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan hereunder will be used
to buy or carry any margin stock.

        Section 7.08    ERISA.

                (a)     Borrower, each Subsidiary and each ERISA Affiliate have
        complied in all material respects with ERISA and, where applicable, the
        Code regarding each Plan.

                (b)     Each Plan is, and has been, maintained in substantial
        compliance with ERISA and, where applicable, the Code.

                (c)     No act, omission or transaction has occurred which could
        result in imposition on Borrower, any Subsidiary or any ERISA Affiliate
        (whether directly or indirectly) of (i) either a civil penalty assessed
        pursuant to section 502(c), (i) or (l) of ERISA or a tax imposed
        pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of
        fiduciary duty liability damages under section 409 of ERISA.

                (d)     No Plan (other than a defined contribution plan) or any
        trust created under any such Plan has been terminated since September 2,
        1974. No liability to the PBGC (other than for the payment of current
        premiums which are not past due) by Borrower, any Subsidiary or any
        ERISA Affiliate has been or is expected by Borrower, any Subsidiary or
        any ERISA Affiliate to be incurred with respect to any Plan. No ERISA
        Event with respect to any Plan has occurred.

                (e)     Full payment when due has been made of all amounts which
        Borrower, any Subsidiary or any ERISA Affiliate is required under the
        terms of each Plan or applicable law to have paid as contributions to
        such Plan, and no accumulated funding deficiency (as defined in section
        302 of ERISA and section 412 of the Code), whether or not waived, exists
        with respect to any Plan.

                (f)     The actuarial present value of the benefit liabilities
        under each Plan which is subject to Title IV of ERISA does not, as of
        the end of Borrower's most recently ended fiscal year, exceed the
        current value of the assets (computed on a plan termination basis in
        accordance with Title IV of ERISA) of such Plan allocable to such
        benefit liabilities. The term "actuarial present value of the benefit
        liabilities" shall have the meaning specified in section 4041 of ERISA.

                (g)     None of Borrower, any Subsidiary or any ERISA Affiliate
        sponsors, maintains, or contributes to an employee welfare benefit plan,
        as defined in section 3(1) of ERISA, including, without limitation, any
        such plan maintained to provide benefits to former employees

                                       36

<PAGE>

        of such entities, that may not be terminated by Borrower, a Subsidiary
        or any ERISA Affiliate in its sole discretion at any time without any
        material liability.

                (h)     None of Borrower, any Subsidiary or any ERISA Affiliate
        sponsors, maintains or contributes to, or has at any time in the
        preceding six calendar years, sponsored, maintained or contributed to,
        any Multiemployer Plan.

                (i)     None of Borrower, any Subsidiary or any ERISA Affiliate
        is required to provide security under section 401(a)(29) of the Code due
        to a Plan amendment that results in an increase in current liability for
        the Plan.

        Section 7.09    Taxes. Except as set out in Schedule 7.09, each of
Borrower and its Subsidiaries has filed all United States Federal income tax
returns and all other tax returns which are required to be filed by them and
have paid all material taxes due pursuant to such returns or pursuant to any
assessment received by Borrower or any Subsidiary. The charges, accruals and
reserves on the books of Borrower and its Subsidiaries in respect of taxes and
other governmental charges are, in the opinion of Borrower, adequate. No tax
lien has been filed and, to the knowledge of Borrower, no claim is being
asserted with respect to any such tax, fee or other charge.

        Section 7.10    Titles, Etc.

                (a)     Except as set out in Schedule 7.10, each of Borrower and
        its Subsidiaries has good and indefeasible title to its material
        (individually or in the aggregate) Properties comprised of real Property
        and has good and marketable title to and is possessed of its material
        (individually or in the aggregate) Properties comprised of personal
        Property, free and clear of all Liens, except Liens permitted by Section
        9.02. Except as set forth in Schedule 7.10, after giving full effect to
        the Excepted Liens, Borrower owns the net interests in production
        attributable to the Hydrocarbon Interests reflected in the most recently
        delivered Reserve Report and the ownership of such Properties shall not
        in any material respect obligate Borrower to bear the costs and expenses
        relating to the maintenance, development and operations of each such
        Property in an amount in excess of the working interest of each Property
        set forth in the most recently delivered Reserve Report. All information
        contained in the most recently delivered Reserve Report is true and
        correct in all material respects as of the date thereof.

                (b)     All leases and agreements necessary for the conduct of
        the business of Borrower and its Subsidiaries are valid and subsisting,
        in full force and effect and there exists no default or event or
        circumstance which with the giving of notice or the passage of time or
        both would give rise to a default under any such lease or leases, which
        would affect in any material respect the conduct of the business of
        Borrower and its Subsidiaries.

                (c)     All of the assets and Properties of Borrower and its
        Subsidiaries which are reasonably necessary for the operation of its
        business are in good working condition and are maintained in accordance
        with prudent business standards.

        Section 7.11    No Material Misstatements. No written information,
statement, exhibit, certificate, document or report furnished to Administrative
Agent and the Lenders (or any of them) by or on behalf of Borrower or any
Subsidiary in connection with the negotiation of this Agreement contained any
material misstatement of fact or omitted to state a material fact or any fact
necessary to make the statement contained therein not materially misleading in
the light of the circumstances in which made and with respect to Borrower and
its Subsidiaries taken as a whole. There is no fact peculiar to Borrower or any
Subsidiary which has a Material Adverse Effect or in the future is reasonably
likely to have (so far as Borrower can now foresee) a Material Adverse Effect
and which has not been set forth in this Agreement

                                       37

<PAGE>

or the other documents, certificates and statements furnished to Administrative
Agent by or on behalf of Borrower or any Subsidiary prior to, or on, the Closing
Date in connection with the transactions contemplated hereby. To the best
knowledge of Borrower, there are no statements or conclusions in any Reserve
Reports which are based upon or include misleading information or fail to take
into account material information regarding the matters reported therein.

        Section 7.12    Investment Company Act. Neither Borrower nor any
Subsidiary is an "investment company" or a company "controlled" by an
"investment company," within the meaning of the Investment Company Act of 1940,
as amended.

        Section 7.13    Subsidiaries. Except as set forth on Schedule 7.13,
Borrower has no Subsidiaries.

        Section 7.14    Location of Business and Offices, Etc. Borrower's
principal place of business and chief executive offices are located at the
address stated on the signature page of this Agreement. The principal place of
business and chief executive office of each Subsidiary are located at the
addresses stated on Schedule 7.14. The tax identification number, organizational
identification number and state of formation for Borrower and each Subsidiary
are set forth on Schedule 7.14.

        Section 7.15    Defaults. Neither Borrower nor any Subsidiary is in
default nor has any event or circumstance occurred which, but for the expiration
of any applicable grace period or the giving of notice, or both, would
constitute a default under any material agreement or instrument to which
Borrower or any Subsidiary is a party or by which Borrower or any Subsidiary is
bound which default would have a Material Adverse Effect. No Default hereunder
has occurred and is continuing.

        Section 7.16    Environmental Matters. Except (i) as provided in
Schedule 7.16 or (ii) as would not have a Material Adverse Effect (or with
respect to (c), (d) and (e) below, where the failure to take such actions would
not have a Material Adverse Effect):

                (a)     Neither any Property of Borrower or any Subsidiary nor
        the operations conducted thereon violate any order or requirement of any
        court or Governmental Authority or any Environmental Laws;

                (b)     Without limitation of clause (a) above, no Property of
        Borrower or any Subsidiary nor the operations currently conducted
        thereon or, to the best knowledge of Borrower, by any prior owner or
        operator of such Property or operation, are in violation of or subject
        to any existing, pending or threatened action, suit, investigation,
        inquiry or proceeding by or before any court or Governmental Authority
        or to any remedial obligations under Environmental Laws;

                (c)     All notices, permits, licenses or similar
        authorizations, if any, required to be obtained or filed in connection
        with the operation or use of any and all Property of Borrower and each
        Subsidiary, including without limitation past or present treatment,
        storage, disposal or release of a hazardous substance or solid waste
        into the environment, have been duly obtained or filed, and Borrower and
        each Subsidiary are in compliance with the terms and conditions of all
        such notices, permits, licenses and similar authorizations;

                (d)     All hazardous substances, solid waste, and oil and gas
        exploration and production wastes, if any, generated at any and all
        Property of Borrower or any Subsidiary have in the past been
        transported, treated and disposed of in accordance with Environmental
        Laws and so as not to pose an imminent and substantial endangerment to
        public health or welfare or the environment, and, to the best knowledge
        of Borrower, all such transport carriers and treatment and disposal
        facilities have been and are operating in compliance with Environmental
        Laws and so as not to

                                       38

<PAGE>

        pose an imminent and substantial endangerment to public health or
        welfare or the environment, and are not the subject of any existing,
        pending or threatened action, investigation or inquiry by any
        Governmental Authority in connection with any Environmental Laws;

                (e)     Borrower has taken all steps reasonably necessary to
        determine and has determined that no hazardous substances, solid waste,
        or oil and gas exploration and production wastes, have been disposed of
        or otherwise released and there has been no threatened release of any
        hazardous substances on or to any Property of Borrower or any Subsidiary
        except in compliance with Environmental Laws and so as not to pose an
        imminent and substantial endangerment to public health or welfare or the
        environment;

                (f)     To the extent applicable, all Property of Borrower and
        each Subsidiary currently satisfies all design, operation, and equipment
        requirements imposed by the OPA or scheduled as of the Closing Date to
        be imposed by OPA during the term of this Agreement, and Borrower does
        not have any reason to believe that such Property, to the extent subject
        to OPA, will not be able to maintain compliance with the OPA
        requirements during the term of this Agreement; and

                (g)     Neither Borrower nor any Subsidiary has any known
        contingent liability in connection with any release or threatened
        release of any oil, hazardous substance or solid waste into the
        environment.

        Section 7.17    Compliance with the Law. Neither Borrower nor any
Subsidiary has violated any Governmental Requirement or failed to obtain any
license, permit, franchise or other governmental authorization necessary for the
ownership of any of its Properties or the conduct of its business, which
violation or failure would have (in the event such violation or failure were
asserted by any Person through appropriate action) a Material Adverse Effect.
Except for such acts or failures to act as would not have a Material Adverse
Effect, the Oil and Gas Properties (and properties unitized therewith) have been
maintained, operated and developed in a good and workmanlike manner and in
conformity with all applicable laws and all rules, regulations and orders of all
duly constituted authorities having jurisdiction and in conformity with the
provisions of all leases, subleases or other contracts comprising a part of the
Hydrocarbon Interests and other contracts and agreements forming a part of the
Oil and Gas Properties. Specifically in this connection, (i) after the Closing
Date, no Oil and Gas Property is subject to having allowable production reduced
below the full and regular allowable (including the maximum permissible
tolerance) because of any overproduction (whether or not the same was
permissible at the time) prior to the Closing Date and (ii) none of the wells
comprising a part of the Oil and Gas Properties (or properties unitized
therewith) are deviated from the vertical more than the maximum permitted by
applicable laws, regulations, rules and orders, and such wells are, in fact,
bottomed under and are producing from, and the well bores are wholly within, the
Oil and Gas Properties (or in the case of wells located on properties unitized
therewith, such unitized properties).

        Section 7.18    Insurance. Schedule 7.18 attached hereto contains an
accurate and complete description of all material policies of fire, liability,
workmen's compensation and other forms of insurance owned or held by Borrower
and each Subsidiary. All such policies are in full force and effect, all
premiums with respect thereto covering all periods up to and including the date
of the closing have been paid, and no notice of cancellation or termination has
been received with respect to any such policy. Such policies are sufficient for
compliance with all requirements of law and of all agreements to which Borrower
or any Subsidiary is a party; are valid, outstanding and enforceable policies;
provide adequate insurance coverage in at least such amounts and against at
least such risks (but including in any event public liability) as are usually
insured against in the same general area by companies engaged in the same or a
similar business for the assets and operations of Borrower and each Subsidiary;
will remain in full force and effect through the respective dates set forth in
Schedule 7.18 without the payment of additional premiums; and will not in any
way be affected by, or terminate or lapse by reason of, the transactions

                                       39

<PAGE>

contemplated by this Agreement. Schedule 7.18 identifies all material risks, if
any, which Borrower and its Subsidiaries and their respective Board of Directors
or officers have designated as being self insured. Neither Borrower nor any
Subsidiary has been refused any insurance with respect to its assets or
operations, nor has its coverage been limited below usual and customary policy
limits, by an insurance carrier to which it has applied for any such insurance
or with which it has carried insurance during the last three years.

        Section 7.19    Hedging Agreements. Schedule 7.19 sets forth, as of the
Closing Date, a true and complete list of all Hedging Agreements (including
commodity price swap agreements, forward agreements or contracts of sale which
provide for prepayment for deferred shipment or delivery of oil, gas or other
commodities) of Borrower and each Subsidiary, the material terms thereof
(including the type, term, effective date, termination date and notional amounts
or volumes), the net mark to market value thereof, all credit support agreements
relating thereto (including any margin required or supplied), and the counter
party to each such agreement.

        Section 7.20    Restriction on Liens. Neither Borrower nor any of its
Subsidiaries is a party to any agreement or arrangement (other than the Loan
Documents), or subject to any order, judgment, writ or decree, which either
restricts or purports to restrict its ability to grant Liens to other Persons on
or in respect of their respective assets or Properties.

        Section 7.21    Material Agreements. Set forth on Schedule 7.21 hereto
is a complete and correct list of all material agreements, leases, purchase
agreements, joint venture agreements and other agreements and contracts in
effect or to be in effect on the Closing Date relating to the operation of
Borrower's and each Subsidiaries business, and all indentures, letters of
credit, guarantees, and other instruments and agreements in effect or to be in
effect as of the Closing Date (other than Hedging Agreements) providing for,
evidencing, securing or otherwise relating to any Debt of Borrower or any of its
Subsidiaries, and all obligations of Borrower or any of its Subsidiaries to
issuers of surety or appeal bonds issued for account of Borrower or any such
Subsidiary, and such list correctly sets forth the names of the debtor or lessee
and creditor or lessor with respect to the Debt or lease obligations outstanding
or to be outstanding and the Property subject to any Lien securing such Debt or
lease obligation. Also set forth on Schedule 7.21 hereto is a complete and
correct list of all material agreements and other instruments of Borrower and
its Subsidiaries relating to the purchase, transportation by pipeline, gas
processing, marketing, sale and supply of natural gas and other Hydrocarbons,
but in any event, any such agreement or other instrument that will account for
more than ten percent (10%) of the sales of Borrower and its Subsidiaries during
Borrower's current fiscal year. Borrower has heretofore delivered to
Administrative Agent and the Lenders a complete and correct copy of the Aspen
Operations Agreement, the Sigma Consulting Agreement, the Jay Management
Agreement, the Jay Management JOA, and all such material agreements, purchase
agreements, joint venture agreements, leases, indentures, letters of credit,
guarantees, or other contracts and instruments, including any modifications or
supplements thereto, as in effect on the date of the Initial Funding.

        Section 7.22    Solvency. Immediately after the Initial Funding and
after giving effect to the application of the proceeds of the Initial Funding,
(a) the fair value of the Property of Borrower, at a fair valuation, will exceed
its debts and liabilities, subordinated, contingent or otherwise; (b) the
present fair saleable value of the Property of Borrower will be greater than the
amount that will be required to pay the probable liability of its debts and
other liabilities, subordinated, contingent or otherwise, as such debts and
other liabilities become absolute and matured; (c) Borrower will be able to pay
its debts and liabilities, subordinated, contingent or otherwise, as such debts
and liabilities become absolute and matured; and (d) Borrower will not have
unreasonably small capital with which to conduct the business in which it is
engaged as such business is now conducted and is proposed to be conducted
following the Initial Funding.

        Section 7.23    Gas Imbalances. Except as set forth on Schedule 7.23 or
on the most recent certificate delivered pursuant to Section 8.07(c), on a net
basis there are no gas imbalances, take or pay or other prepayments with respect
to Borrower's Oil and Gas Properties which would require Borrower to deliver, in
the aggregate, two percent (2.0%) or more of the monthly production from
Hydrocarbons produced from Borrower's Oil and Gas Properties at some future time
without then or thereafter receiving full payment therefor.

        Section 7.24    Permits, Licenses, Franchises, Patents and Trademarks.
Borrower and each Subsidiary has all permits and owns or is licensed or
otherwise has the right to use all of the patents, trademarks, trade names,
copyrights, franchises, licenses and rights, as the case may be, necessary for
the conduct of its business, which ownership, patents, trademarks, trade names,
copyrights, licenses, franchises, permits and rights of Borrower and each
Subsidiary, as the case may be, are free and clear of Liens, except for Liens
permitted by the Loan Documents. There does not exist, nor to the knowledge of
Borrower, has there been threatened against Borrower or any Subsidiary, any
material liability of Borrower or any Subsidiary in respect of any claim or
infringement of any of the foregoing.

        times the state and condition of its Oil and Gas Properties and other
        material Properties will be fully preserved and maintained, except to
        the extent a portion of such Properties is no longer capable of
        producing Hydrocarbons in economically reasonable amounts. Borrower will
        and will cause each

                                       44

<PAGE>

        Subsidiary to promptly: (i) pay and discharge, or make reasonable and

        cause each Subsidiary to establish and implement such procedures as may

        endangerment to public health or welfare or the environment.

                (b)     Notice of Action. Borrower will promptly notify
        Administrative Agent and the Lenders in writing of any threatened
        action, investigation or inquiry by any Governmental Authority of which

        before November 1 of each year Borrower shall furnish, or cause to be
        furnished, to Administrative Agent and the Lenders the as of June 30
        Reserve Report. The as of December 31 Reserve Report of each year shall
        be prepared by certified independent petroleum engineers or other
        independent petroleum consultant(s) acceptable to Administrative Agent
        and the as of June 30 Reserve Report of each year shall be prepared by
        or under the supervision of the chief engineer of Borrower who shall
        certify such Reserve Report to be true and accurate and to have been
        prepared in accordance with the procedures used in the immediately
        proceeding as of December 31 Reserve Report.

                (b)     Unscheduled Redetermination. In the event of an
        unscheduled redetermination, Borrower shall furnish to Administrative
        Agent and the Lenders a Reserve Report prepared by or under the
        supervision of the chief engineer of Borrower who shall certify such
        Reserve Report to be true and accurate and to have been prepared in
        accordance with the procedures used in the immediately preceding Reserve
        Report. For any unscheduled redetermination requested by the Majority
        Lenders or Administrative Agent pursuant to Section 2.08(e), Borrower
        shall provide as soon as possible, but in any event no later than 30
        days following the receipt of the request by Administrative Agent, such
        Reserve Report with an "as of" date not more than 60 days prior to the
        anticipated date of redetermination or as otherwise required by the
        Majority Lenders or Administrative Agent.

        Section 8.08    Title Information.

                (a)     Delivery. On or before the delivery to Administrative
        Agent and the Lenders of each Reserve Report required by Section
        8.07(a), Borrower will deliver title information in form and substance
        acceptable to Administrative Agent covering enough of the Oil and Gas
        Properties evaluated by such Reserve Report that were not included in
        the immediately preceding Reserve Report, so that Administrative Agent
        shall have received together with title information previously delivered
        to Administrative Agent, satisfactory title information on at least
        eighty percent (80%) of the value of the Oil and Gas Properties
        evaluated by such Reserve Report.

                (b)     Cure of Title Defects. Borrower shall cure any title
        defects or exceptions which are not Excepted Liens raised by the
        information described in Section 8.08(a), or substitute as Collateral
        acceptable Oil and Gas Properties with no title defects or exceptions
        except for Excepted Liens covering Oil and Gas Properties of an
        equivalent value (but for such title defects or exceptions), within 60
        days after a request by Administrative Agent or the Lenders to cure such
        defects or exceptions.

                (c)     Failure to Cure Title Defects. If Borrower is unable to
        cure any title defect requested by Administrative Agent or the Lenders
        to be cured within the 60 day period or Borrower does not comply with
        the requirements to provide acceptable title information covering

                                       46

<PAGE>

        eighty percent (80%) of the value of the Oil and Gas Properties
        evaluated in the most recent Reserve Report, such default shall not be a
        Default or an Event of Default, but instead Administrative Agent and the
        Lenders shall have the right to exercise, in their sole discretion from
        time to time, the remedy described in the next sentence, and any failure
        to so exercise this remedy at any time shall not be a waiver as to
        future exercise of such remedy by Administrative Agent or the Lenders.
        To the extent that Administrative Agent or the Lenders are not satisfied
        with title to any Oil and Gas Properties comprising Collateral after the
        time period in Section 8.08(b) has elapsed, such unacceptable Oil and
        Gas Property Collateral shall not count towards the eighty percent (80%)
        requirement, and Administrative Agent may send a notice to Borrower and
        the Lenders that the then outstanding Borrowing Base shall be reduced by
        an amount as determined by all of the Lenders to cause Borrower to be in
        compliance with the requirement to provide acceptable title information
        on eighty percent (80%) of the value of the Oil and Gas Properties
        comprising Collateral. This new Borrowing Base shall become effective
        immediately after receipt of such notice.

        Section 8.09    Collateral.

                (a)     Collateral. The Obligations shall be secured by a
        perfected first priority Lien (subject only to Excepted Liens) granted
        to Administrative Agent for the benefit of the Beneficiaries in (i) all
        of Borrower's and its Subsidiaries' rights, titles and interests, now
        owned or hereafter acquired, in any Oil and Gas Properties, and
        contracts and any other rights related thereto, (ii) all personal
        Property of Borrower and its Subsidiaries and (iii) all of the issued
        and outstanding capital stock, partnership interests, member interest or
        other equity interest of all existing and/or hereafter created and/or
        acquired Subsidiaries of Borrower.

                (b)     Lien in Acquired Oil and Gas Properties. Should Borrower
        or any of its Subsidiaries acquire any additional Oil and Gas Properties
        or additional interests in its existing Oil and Gas Properties, Borrower
        and/or such Subsidiary, as applicable, will grant to Administrative
        Agent as security for the Obligations a first priority Lien interest
        (subject only to Excepted Liens) on Borrower's or such Subsidiary's
        interest in any Oil and Gas Properties not already subject to a Lien of
        the Security Instruments, which Lien will be created and perfected by
        and in accordance with the provisions of mortgages, deeds of trust,
        security agreements and financing statements, or other Security
        Instruments, all in form and substance satisfactory to Administrative
        Agent in its sole discretion and in sufficient executed (and
        acknowledged where necessary or appropriate) counterparts for recording
        purposes.

                (c)     Title Information. Concurrently with the granting of the
        Lien or other action referred to in Subsection (b) of this Section,
        Borrower will provide, or cause to be provided, to Administrative Agent
        title information in form and substance satisfactory to Administrative
        Agent in its sole discretion with respect to Borrower's and each
        Subsidiary's interests in its Oil and Gas Properties.

                (d)     Legal Opinions. Also, concurrently with the filing of
        any new Security Instrument in any state wherein Security Instruments
        have not previously been filed or there is reason to believe the law
        applicable to Security Instruments may have changed, upon the reasonable
        request of Administrative Agent, Borrower will provide to Administrative
        Agent an opinion addressed to Administrative Agent for the benefit of
        the Lenders in form and substance satisfactory to Administrative Agent
        in its sole discretion from counsel acceptable to Administrative Agent,
        stating that the Security Instrument is valid, binding and enforceable
        in accordance with its terms in legally sufficient form for such
        jurisdiction, and the means by which such Security Instrument will
        perfect the Lien created thereby.

Internal Revenue Service or the PBGC, copies of each annual and other report
with respect to each Plan or any trust created thereunder, (ii) immediately upon
becoming aware of the occurrence of any ERISA Event or of any "prohibited
transaction," as described in section 406 of ERISA or in section 4975 of the
Code, in connection with any Plan or any trust created thereunder, a written
notice signed by a Responsible Officer specifying the nature thereof, what
action Borrower, the Subsidiary or the ERISA Affiliate is taking or proposes to
take with respect thereto, and, when known, any action taken or proposed by the
Internal Revenue Service, the Department of Labor or the PBGC with respect
thereto, and (iii) immediately upon receipt thereof, copies of any notice of the
PBGC's intention to terminate or to have a trustee appointed to administer any
Plan. With respect to each Plan (other than a Multiemployer Plan), Borrower
will, and will cause each Subsidiary and ERISA Affiliate to, (i) satisfy in full
and in a timely manner, without incurring any late payment or underpayment
charge or penalty and without giving rise to any lien, all of the contribution
and funding requirements of section 412 of the Code (determined without regard
to subsections (d), (e), (f) and (k) thereof) and of section 302 of ERISA
(determined without regard to sections 303, 304 and 306 of ERISA), and (ii) pay,
or cause to be paid, to the PBGC in a timely manner, without incurring any late
payment or underpayment charge or penalty, all premiums required pursuant to
sections 4006 and 4007 of ERISA.

Agreements; provided that such Hedging Agreements (i) are in form and substance
satisfactory to Administrative Agent and the Majority Lenders (ii) shall be with
a Lender or, as approved by Administrative Agent and the Majority Lenders, other

business operations as a risk management strategy and/or hedge against changes
resulting from market conditions related to Borrower's operations, and (iv)
shall not at any time, in the aggregate, cover more than eighty percent (80%) of
estimated production of Hydrocarbons of Borrower from its Oil and Gas Properties
for each individual period covered by Hedging Agreements. At any time that
Borrower has Loans outstanding in an amount exceeding seventy-five percent (75%)
of the Borrowing Base, the Lenders may require Borrower to maintain Hedging
Agreements or other contractual agreements upon terms, including projected
production volumes, and pursuant to documentation, in form and substance
satisfactory to Administrative Agent and the Majority Lenders. For purposes of
this Section 8.11, the notional volumes and corresponding swap volumes so
determined shall be calculated and recorded separately for natural gas and crude
oil, and natural gas volumes shall include associated natural gas liquids
volumes. In no event shall any Hedging Agreement contain any current
requirement, agreement or covenant for the Borrower or any Subsidiary to pledge
collateral or post margin, to secure their obligations under such Hedging
Agreements or to cover market exposures.

        Coverage Ratio" shall mean the ratio of (i) EBITDAX for the four fiscal
        quarters ending on such date to (ii) cash interest payments made for

        For purposes of the calculations in this Section to be made prior to the
        fourth full fiscal quarter to elapse after the Closing Date, EBITDAX and
        the amount of cash interest payments shall be determined by multiplying
        the sum of each such component for each of the fiscal quarters actually
        elapsed from and including the first fiscal quarter of 2007 through and
        including the fourth fiscal quarter of 2007 by a fraction, the numerator
        of which is 4 and the denominator of which is the number of such
        actually elapsed fiscal quarters.

therewith.

                              ADMINISTRATIVE AGENT

        Section 11.01   Appointment, Powers and Immunities. Each Lender hereby
irrevocably appoints and authorizes Administrative Agent to act as its agent
hereunder and under the other Loan Documents with such powers as are
specifically delegated to Administrative Agent by the terms of this Agreement
and the other Loan Documents, together with such other powers as are reasonably
incidental thereto. Administrative Agent (which term as used in this sentence
and in Section 11.05 and the first sentence of Section 11.06 shall include
reference to its Affiliates and its and its Affiliates' officers, directors,
employees, attorneys, accountants, experts and agents): (i) shall have no duties
or responsibilities except those expressly set forth in the Loan Documents, and
shall not by reason of the Loan Documents be a trustee or fiduciary for any
Lender; (ii) makes no representation or warranty to any Lender and shall not be
responsible to the Lenders for any recitals, statements, representations or
warranties contained in this Agreement, or in any certificate or other document
referred to or provided for in, or received by any of them under, this
Agreement, or for the value, validity, effectiveness, genuineness, execution,
effectiveness, legality, enforceability or sufficiency of this Agreement, any
Note or any other document referred to or provided for herein or for any failure
by Borrower or any other Person (other than Administrative Agent) to perform any
of its obligations hereunder or thereunder or for the existence, value,
perfection or priority of any collateral security or the financial or other
condition of Borrower, its Subsidiaries or any other obligor or guarantor; (iii)
except pursuant to Section 11.07 shall not be required to initiate or conduct
any litigation or collection proceedings hereunder; and (iv) shall not be
responsible for any action taken or omitted to be taken by it hereunder or under
any other document or instrument referred to or provided for herein or in
connection herewith including its own ordinary negligence, except for its own
gross negligence or willful misconduct. Administrative Agent may employ agents,
accountants, attorneys and experts and shall not be responsible for the
negligence or misconduct of any such agents, accountants, attorneys or experts
selected by it in good faith or any action taken or omitted to be taken in good
faith by it in accordance with the advice of such agents, accountants, attorneys
or experts. Administrative Agent may deem and treat the payee of any Note as the
holder thereof for all purposes hereof unless and until a written notice of the
assignment or transfer thereof permitted hereunder shall have been filed with
Administrative Agent. Administrative Agent is authorized to release any
collateral that is permitted to be sold or released pursuant to the terms of the
Loan Documents.

        Section 11.02   Reliance by Administrative Agent. Administrative Agent
shall be entitled to rely upon any certification, notice or other communication
(including any thereof by telephone, telex, telecopier, telegram or cable)
believed by it to be genuine and correct and to have been signed or sent by or
on behalf of the proper Person or Persons, and upon advice and statements of
legal counsel, independent accountants and other experts selected by
Administrative Agent.

        Section 11.03   Defaults. Administrative Agent shall not be deemed to
have knowledge of the occurrence of a Default (other than the non-payment of
principal of or interest on Loans or of fees or failure to reimburse for Letter
of Credit drawings) unless Administrative Agent has received notice from a
Lender or Borrower specifying such Default and stating that such notice is a
"Notice of Default." In the event that Administrative Agent receives such a
notice of the occurrence of a Default, Administrative Agent shall give prompt
notice thereof to the Lenders. In the event of a payment Default, Administrative
Agent shall give each Lender prompt notice of each such payment Default.

        Section 11.04   Rights as a Lender. With respect to its Commitments and
the Loans made by it and its participation in the issuance of Letters of Credit,
WFB (and any successor acting as Administrative Agent) in its capacity as a
Lender hereunder shall have the same rights and powers hereunder as any other
Lender and may exercise the same as though it were not acting as Administrative
Agent, and the term "Lender" or "Lenders" shall, unless the context otherwise
indicates, include Administrative Agent in its individual capacity. WFB (and any
successor acting as Administrative Agent) and its Affiliates may (without having
to account therefor to any Lender) accept deposits from, lend money to and
generally engage in any kind of banking, trust or other business with Borrower
(and any of its Affiliates) as if it were not acting as Administrative Agent,
and WFB and its Affiliates may accept fees and other consideration from Borrower
for services in connection with this Agreement or otherwise without having to
account for the same to the Lenders.

        Section 11.05   Indemnification. The Lenders agree to indemnify
Administrative Agent and the Issuing Bank ratably in accordance with their
Percentage Shares for the Indemnity Matters as described in section 12.03 to the
extent not indemnified or reimbursed by Borrower under section 12.03, but
without limiting the obligations of Borrower under said section 12.03 and for
any and all other liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind and nature
whatsoever which may be imposed on, incurred by or asserted against
Administrative Agent or the Issuing Bank in any way relating to or arising out
of: (i) this Agreement, the other Loan Documents or any other documents
contemplated by or referred to herein or the transactions contemplated hereby,
but excluding, unless a Default has occurred and is continuing, normal
administrative costs and expenses incident to the performance of its agency
duties hereunder or (ii) the enforcement of any of the terms of this Agreement,
any Loan Document or of any such other documents; whether or not any of the
foregoing specified in this section 11.05 arises from the sole or concurrent
negligence of Administrative Agent or the Issuing Bank, provided that no Lender
shall be liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of Administrative Agent.

        Section 11.06   Non-Reliance on Administrative Agent and other Lenders.
Each Lender acknowledges and agrees that it has, independently and without
reliance on Administrative Agent or any other Lender, and based on such
documents and information as it has deemed appropriate, made its own credit
analysis of Borrower and its decision to enter into this Agreement, and that it
will, independently and without reliance upon 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 analysis and decisions in taking or not
taking action under this Agreement. Administrative Agent shall not be required
to keep itself informed as to the performance or observance by Borrower of this
Agreement, the Notes, any other Loan Document or any other document referred to
or provided for herein or to inspect the properties or books of Borrower. Except
for notices, reports and other documents and information expressly required

                                       57

<PAGE>

to be furnished to the Lenders by Administrative Agent hereunder, Administrative
Agent shall not have any duty or responsibility to provide any Lender with any
credit or other information concerning the affairs, financial condition or
business of Borrower (or any of its Affiliates) which may come into the
possession of Administrative Agent or any of its Affiliates. In this regard,
each Lender acknowledges that Burleson Cooke L.L.P. is acting in this
transaction as special counsel to Administrative Agent only, except to the
extent otherwise expressly stated in any legal opinion or any Loan Document.
Each Lender will consult with its own legal counsel to the extent that it deems
necessary in connection with the Loan Documents and the matters contemplated
therein.

        Section 11.07    Action by Administrative Agent. Except for action or
other matters expressly required of Administrative Agent hereunder,
Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder unless it shall (i) receive written instructions from
the Majority Lenders (or all of the Lenders as expressly required by Section
12.04) specifying the action to be taken, and (ii) be indemnified to its
satisfaction by the Lenders against any and all liability and expenses which may
be incurred by it by reason of taking or continuing to take any such action. The
instructions of the Majority Lenders (or all of the Lenders as expressly
required by Section 12.04) and any action taken or failure to act pursuant
thereto by Administrative Agent shall be binding on all of the Lenders. If a
Default has occurred and is continuing, Administrative Agent shall take such
action with respect to such Default as shall be directed by the Majority Lenders
(or all of the Lenders as required by Section 12.04) in the written instructions
(with indemnities) described in this Section 11.07, provided that, unless and
until Administrative Agent shall have received such directions, Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default as it shall deem advisable in
the best interests of the Lenders. In no event, however, shall Administrative
Agent be required to take any action which exposes Administrative Agent to
personal liability or which is contrary to this Agreement and the other Loan
Documents or applicable law. In connection with taking any action pursuant to
this Section or otherwise under this Agreement, Administrative Agent may engage
legal counsel and/or other qualified consultants to act at the instructions of
and on behalf of Administrative Agent, and such legal counsel and/or consultants
shall be afforded all of the indemnities and other protections afforded to
Administrative Agent pursuant to Article XI.

        Section 11.08    Resignation of Administrative Agent. Subject to the
appointment and acceptance of a successor Administrative Agent as provided
below, Administrative Agent may resign at any time by giving notice thereof to
the Lenders and Borrower. Upon any such resignation, the Majority Lenders shall
have the right to appoint a successor Administrative Agent. If no successor
Administrative Agent shall have been so appointed by the Majority Lenders and
shall have accepted such appointment within thirty (30) days after the resigning
Administrative Agent's giving of notice of resignation, then the resigning
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent. Upon the acceptance of such appointment hereunder by a
successor Administrative Agent, such successor Administrative Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the resigning Administrative Agent, and the resigning
Administrative Agent shall be discharged from its duties and obligations
hereunder. After any resigning Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Article XI and Section 12.03 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as Administrative Agent.

                                   ARTICLE XII

                                  MISCELLANEOUS

        Section 12.01   Waiver. No failure on the part of Administrative Agent
or any Lender to exercise and no delay in exercising, and no course of dealing
with respect to, any right, power or privilege under any of the Loan Documents
shall operate as a waiver thereof, nor shall any single or partial exercise

                                       58

of any right, power or privilege under any of the Loan Documents preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. The remedies provided herein are cumulative and not exclusive of any
remedies provided by law.

        Section 12.06   Assignments and Participations.

                (a)     Borrower may not assign its rights or obligations
        hereunder or under the Notes or any Letters of Credit without the prior
        consent of all of the Lenders and Administrative Agent.

                (b)     Any Lender may assign to one or more assignees all or a
        portion of its rights and obligations under this Agreement pursuant to
        an Assignment Agreement substantially in the form of Exhibit E (an
        "Assignment"); provided, however, that (i) except in the case of an
        assignment to a Lender or a Lender Affiliate, such assignment shall
        require the written consent of Administrative Agent and, if no Event of
        Default has occurred and is continuing, Borrower (which consent will not
        be unreasonably withheld), (ii) except in the case of an assignment to a
        Lender or a Lender Affiliate, any such assignment shall be in the amount
        of at least $5,000,000 or such lesser amount to which Borrower and
        Administrative Agent have consented and if the assigning Lender has
        assigned less than all of its Percentage Share of the Loans, such
        assigning Lender shall retain a Percentage Share of the Loans equating
        to at least $5,000,000 or such lesser amount to which Borrower and
        Administrative Agent have consented and (iii) the assignee or assignor
        shall pay to Administrative Agent a processing and recordation fee of
        $5,000 for each

                                       61

<PAGE>

        assignment. Any such assignment will become effective upon the execution
        and delivery to Administrative Agent of the Assignment, payment of the
        recordation fee and, if required, the consent of Administrative Agent
        and Borrower. Promptly after receipt of an executed Assignment,
        Administrative Agent shall send to Borrower a copy of such executed
        Assignment. Upon receipt of such executed Assignment, Borrower, will, at
        its own expense, execute and deliver new Notes to the assignor and/or
        assignee, as appropriate, in accordance with their respective interests
        as they appear. Upon the effectiveness of any assignment pursuant to
        this Section 12.06(b), the assignee will become a "Lender," if not
        already a "Lender," for all purposes of this Agreement and the other
        Loan Documents. The assignor shall be relieved of its obligations
        hereunder to the extent of such assignment (and if the assigning Lender
        no longer holds any rights or obligations under this Agreement, such
        assigning Lender shall cease to be a "Lender" hereunder except that its
        rights under Sections 4.06, 5.01, 5.05 and 12.03 shall not be affected).
        Administrative Agent will prepare on the last Business Day of each month
        during which an assignment has become effective pursuant to this Section
        12.06(b), a new Annex I giving effect to all such assignments effected
        during such month, and will promptly provide the same to Borrower and
        each of the Lenders. Any assignment or transfer by a Lender of rights or
        obligations under this Agreement that does not comply with this Section
        12.06(b) shall be treated for purposes of this Agreement as a sale by
        such Lender of a participation in such rights and obligations in
        accordance with Section 12.06(c).

                (c)     Each Lender may, without the consent of Borrower,
        Administrative Agent or the Issuing Bank, transfer, grant or assign
        participations in all or any part of such Lender's interests hereunder
        pursuant to this Section 12.06(c) to any Person, provided that: (i) such
        Lender shall remain a "Lender" for all purposes of this Agreement and
        the transferee of such participation shall not constitute a "Lender"
        hereunder, (ii) such Lender's obligations under this Agreement shall
        remain unchanged, (ii) such Lender shall remain solely responsible to
        the other parties hereto for the performance of such obligations and
        (iv) Borrower, Administrative Agent, the Issuing Bank and the other
        Lenders shall continue to deal solely and directly with such Lender in
        connection with such Lender's rights and obligations under this
        Agreement. Any agreement or instrument pursuant to which a Lender sells
        such a participation shall provide that such Lender shall retain the
        sole right to enforce the Loan Documents and to approve any amendment,
        modification or waiver of any provision of the Loan Documents; provided
        that such agreement or instrument may provide that such Lender will not,
        without the consent of the participant, agree to any amendment,
        modification or waiver that would (x) forgive any principal owing on any
        Obligations or extend the final maturity of the Loans, (y) reduce the
        interest rate (other than as a result of waiving the applicability of
        any Post Default increases in interest rates) or fees applicable to any
        of the Commitments, Loans or Letters of Credit in which such participant
        is participating, or postpone the payment of any thereof, or (z) release
        any guarantor of the Obligations or release all or substantially all of
        the collateral (except as provided in the Loan Documents) supporting any
        of the Commitments, Loans or Letters of Credit in which such participant
        is participating. In the case of any such participation, the participant
        shall not have any rights under this Agreement or any of the other Loan
        Documents (the participant's rights against the granting Lender in
        respect of such participation to be those set forth in the agreement
        with such Lender creating such participation), and all amounts payable
        by Borrower hereunder shall be determined as if such Lender had not sold
        such participation, provided that such participant shall be entitled to
        receive additional amounts under Article V on the same basis as if it
        were a Lender and be indemnified under Section 12.03 as if it were a
        Lender. In addition, each agreement creating any participation must
        include an agreement by the participant to be bound by the provisions of
        Section 12.14.

                (d)     The Lenders may furnish any information concerning
        Borrower in the possession of the Lenders from time to time to assignees
        and participants (including prospective assignees

                                       62

<PAGE>

        and participants); provided that, such Persons agree to be bound by the
        provisions of Section 12.14.

                (e)     Notwithstanding anything in this Section 12.06 to the
        contrary, any Lender may assign and pledge its Note to any Federal
        Reserve Bank No such assignment and/or pledge shall release the
        assigning and/or pledging Lender from its obligations hereunder.

                (f)     Notwithstanding any other provisions of this Section
        12.06, no transfer or assignment of the interests or obligations of any
        Lender or any grant of participations therein shall be permitted if such
        transfer, assignment or grant would require Borrower to file a
        registration statement with the SEC or to qualify the Loans under the
        "Blue Sky" laws of any state.

        Section 12.07   Invalidity. In the event that any one or more of the
provisions contained in any of the Loan Documents, the Letters of Credit or the
Letter of Credit Agreements shall, for any reason, be held invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provision of the Notes, this Agreement or any other
Loan Document.

        Section 12.08   Counterparts; Electronic Delivery of Signature Page.
This Agreement may be executed in any number of counterparts, all of which taken
together shall constitute one and the same instrument and any of the parties
hereto may execute this Agreement by signing any such counterpart. Delivery of a
manually executed signature page of this Agreement by facsimile, e-mail or other
electronic means shall be effective as delivery of an original executed
signature page of this Agreement and shall be binding on the parties hereto.

        Section 12.09   Survival. The obligations of the parties under Section
4.06, Article V, and Sections 11.05 and 12.03 shall survive the repayment of the
Loans and the termination of the Commitments. To the extent that any payments on
the Obligations or proceeds of any collateral are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee, debtor in possession, receiver or other Person under any bankruptcy
law, common law or equitable cause, then to such extent, the Obligations so
satisfied shall be revived and continue as if such payment or proceeds had not
been received and Administrative Agent's and the Lenders' Liens, security
interests, rights, powers and remedies under this Agreement and each of the
other Loan Documents shall continue in full force and effect. In such event,
each Loan Document shall be automatically reinstated and Borrower shall take
such action as may be reasonably requested by Administrative Agent and the
Lenders to effect such reinstatement.

the interpretation of any provision of this Agreement.

        SECTION 12.11   NO ORAL AGREEMENTS. THE LOAN DOCUMENTS EMBODY THE ENTIRE
AGREEMENT AND UNDERSTANDING BETWEEN THE PARTIES AND SUPERSEDE ALL OTHER
AGREEMENTS AND UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE SUBJECT
MATTER HEREOF AND THEREOF. THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT
BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,

<PAGE>

                (A)     THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND
        CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS, EXCEPT TO
        THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CHARGE
        INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER
        IS LOCATED. CH. 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES CERTAIN
        REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL
        NOT APPLY TO THIS AGREEMENT OR THE NOTES.

                (B)     ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN
        DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE
        UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS, AND, BY
        EXECUTION AND DELIVERY OF THIS AGREEMENT, BORROWER HEREBY ACCEPTS FOR
        ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY,
        GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS.
        BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT
        LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS
        OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
        BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE
        JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES
        NOT PRECLUDE ADMINISTRATIVE AGENT OR ANY LENDER FROM OBTAINING
        JURISDICTION OVER BORROWER IN ANY COURT OTHERWISE HAVING JURISDICTION.

                (C)     BORROWER HEREBY IRREVOCABLY CONSENTS TO THE SERVICE OF
        PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR
        PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED
        MAIL, POSTAGE PREPAID, TO BORROWER AT ITS SAID ADDRESS, SUCH SERVICE TO
        BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING HEREIN
        SHALL AFFECT THE RIGHT OF ADMINISTRATIVE AGENT, ANY LENDER OR ANY HOLDER
        OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO
        COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST BORROWER OR ITS
        PROPERTIES IN ANY OTHER JURISDICTION.

                (D)     BORROWER, ADMINISTRATIVE AGENT AND EACH LENDER HEREBY
        (I) IRREVOCABLY AND UNCONDITIONALLY WAIVE, TO THE FULLEST EXTENT
        PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING
        RELATING TO THIS AGREEMENT OR ANY LOAN DOCUMENT AND FOR ANY COUNTERCLAIM
        THEREIN; (II) IRREVOCABLY WAIVE, TO THE MAXIMUM EXTENT NOT PROHIBITED BY
        LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION
        ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES
        OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (III) CERTIFY THAT NO
        PARTY HERETO NOR ANY REPRESENTATIVE, AGENT OR COUNSEL FOR ANY PARTY
        HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH
        PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
        FOREGOING WAIVERS, AND (IV) ACKNOWLEDGE THAT IT HAS BEEN INDUCED TO
        ENTER INTO THIS CREDIT AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE
        TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE
        MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 12.12.

        Section 12.13   Interest. It is the intention of the parties hereto that
each Lender shall conform strictly to usury laws applicable to it. Accordingly,
if the transactions contemplated hereby would be usurious as to any Lender under
laws applicable to it (including the laws of the United States of America and
the State of Texas or any other jurisdiction whose laws may be mandatorily
applicable to such Lender notwithstanding the other provisions of this
Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as
security for the Notes, it is agreed as follows: (i) the aggregate of all
consideration which constitutes

                                       64

<PAGE>

interest under law applicable to any Lender that is contracted for, taken,
reserved, charged or received by such Lender under any of the Loan Documents or
agreements or otherwise in connection with the Notes shall under no
circumstances exceed the maximum amount allowed by such applicable law, and any
excess shall be canceled automatically and if theretofore paid shall be credited
by such Lender on the principal amount of the Obligations (or, to the extent
that the principal amount of the Obligations shall have been or would thereby be
paid in full, refunded by such Lender to Borrower); and (ii) in the event that
the maturity of the Notes is accelerated by reason of an election of the holder
thereof resulting from any Event of Default under this Agreement or otherwise,
or in the event of any required or permitted prepayment, then such consideration
that constitutes interest under law applicable to any Lender may never include
more than the maximum amount allowed by such applicable law, and excess
interest, if any, provided for in this Agreement or otherwise shall be canceled
automatically by such Lender as of the date of such acceleration or prepayment
and, if theretofore paid, shall be credited by such Lender on the principal
amount of the Obligations (or, to the extent that the principal amount of the
Obligations shall have been or would thereby be paid in full, refunded by such
Lender to Borrower). All sums paid or agreed to be paid to any Lender for the
use, forbearance or detention of sums due hereunder shall, to the extent
permitted by law applicable to such Lender, be amortized, prorated, allocated
and spread throughout the full term of the Loans evidenced by the Notes until
payment in full so that the rate or amount of interest on account of any Loans
hereunder does not exceed the maximum amount allowed by such applicable law. If
at any time and from time to time (i) the amount of interest payable to any
Lender on any date shall be computed at the Highest Lawful Rate applicable to
such Lender pursuant to this Section 12.13 and (ii) in respect of any subsequent
interest computation period the amount of interest otherwise payable to such
Lender would be less than the amount of interest payable to such Lender computed
at the Highest Lawful Rate applicable to such Lender, then the amount of
interest payable to such Lender in respect of such subsequent interest
computation period shall continue to be computed at the Highest Lawful Rate
applicable to such Lender until the total amount of interest payable to such
Lender shall equal the total amount of interest which would have been payable to
such Lender if the total amount of interest had been computed without giving
effect to this Section 12.13. To the extent that Chapter 303 of the Texas
Finance Code is relevant for the purpose of determining the Highest Lawful Rate,
such Lender elects to determine the applicable rate ceiling under such Chapter
by the indicated weekly rate ceiling from time to time in effect.

        Section 12.14   Confidentiality. In the event that Borrower provides to
Administrative Agent or the Lenders written confidential information belonging
to Borrower, if Borrower shall denominate such information in writing as
"confidential", Administrative Agent and the Lenders shall thereafter maintain
such information in confidence in accordance with the standards of care and
diligence that each utilizes in maintaining its own confidential information.
This obligation of confidence shall not apply to such portions of the
information which (i) are in the public domain, (ii) hereafter become part of
the public domain without Administrative Agent or the Lenders breaching their
obligation of confidence to Borrower, (iii) are previously known by
Administrative Agent or the Lenders from some source other than Borrower, (iv)
are hereafter developed by Administrative Agent or the Lenders without using
Borrower's information, (v) are hereafter obtained by or available to
Administrative Agent or the Lenders from a third party who owes no obligation of
confidence to Borrower with respect to such information or through any other
means other than through disclosure by Borrower, (vi) are disclosed with
Borrower's consent, (vii) must be disclosed either pursuant to any Governmental
Requirement or to Persons regulating the activities of Administrative Agent or
the Lenders, or (viii) as may be required by law or regulation or order of any
Governmental Authority in any judicial, arbitration or governmental proceeding.
Further, Administrative Agent or a Lender may disclose any such information to
any other Lender, any independent petroleum engineers or consultants, any
independent certified public accountants, any legal counsel employed by such
Person in connection with this Agreement or any other Loan Document, including
without limitation, the enforcement or exercise of all rights and remedies
thereunder, or any assignee or participant (including prospective assignees and
participants) in the Loans; provided, however, that Administrative Agent or the
Lenders shall receive a confidentiality agreement

                                       65

<PAGE>

from the Person to whom such information is disclosed such that said Person
shall have the same obligation to maintain the confidentiality of such
information as is imposed upon Administrative Agent or the Lenders hereunder.
Notwithstanding anything to the contrary provided herein, this obligation of
confidence shall cease three (3) years from the date the information was
furnished, unless Borrower requests in writing at least thirty (30) days prior
to the expiration of such three year period, to maintain the confidentiality of
such information for an additional three year period. Borrower waives any and
all other rights it may have to confidentiality as against Administrative Agent
and the Lenders arising by contract, agreement, statute or law except as
expressly stated in this Section 12.14.

        Section 12.15   USA Patriot Act. Each Lender hereby notifies 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 Borrower, which
information includes the name and address of Borrower and other information that
will allow such Lender to identify Borrower in accordance with the Act.

        Section 12.16   Exculpation Provisions. Each of the parties hereto
specifically agrees that it has a duty to read this Agreement and the other Loan
Documents and agrees that it is charged with notice and knowledge of the terms
of this Agreement and the other Loan Documents; that it has in fact read this
Agreement and is fully informed and has full notice and knowledge of the terms,
conditions and effects of this Agreement; that it has been represented by
independent legal counsel of its choice throughout the negotiations preceding
its execution of this Agreement and the other Loan Documents; and has received
the advice of its attorney in entering into this Agreement and the other Loan
Documents; and that it recognizes that certain of the terms of this Agreement
and the other Loan Documents result in one party assuming the liability inherent
in some aspects of the transaction and relieving the other party of its
responsibility for such liability. Each party hereto agrees and covenants that
it will not contest the validity or enforceability of any exculpatory provision
of this Agreement and the other Loan Documents on the basis that the party had
no notice or knowledge of such provision or that the provision is not
"conspicuous."

        Section 12.17   Arbitration.

                (a)     Arbitration. The parties hereto agree, upon demand by
        any party, to submit to binding arbitration all claims, disputes and
        controversies between or among them (and their respective employees,
        officers, directors, attorneys, and other agents), whether in tort,
        contract or otherwise arising out of or relating to in any way (i) the
        loan and related Loan Documents which are the subject of this Agreement
        and its negotiation, execution, collateralization, administration,
        repayment, modification, extension, substitution, formation, inducement,
        enforcement, default or termination; or (ii) requests for additional
        credit.

                (b)     Governing Rules. Any arbitration proceeding will (i)
        proceed in a location in Texas selected by the American Arbitration
        Association ("AAA"); (ii) be governed by the Federal Arbitration Act
        (Title 9 of the United States Code), notwithstanding any conflicting
        choice of law provision in any of the documents between the parties; and
        (iii) be conducted by the AAA, or such other administrator as the
        parties shall mutually agree upon, in accordance with the AAA's
        commercial dispute resolution procedures, unless the claim or
        counterclaim is at least $1,000,000.00 exclusive of claimed interest,
        arbitration fees and costs in which case the arbitration shall be
        conducted in accordance with the AAA's optional procedures for large,
        complex commercial disputes (the commercial dispute resolution
        procedures or the optional procedures for large, complex commercial
        disputes to be referred to, as applicable, as the "Rules"). If there is
        any inconsistency between the terms hereof and the Rules, the terms and
        procedures set forth herein shall control. Any party who fails or
        refuses to submit to arbitration following a demand by any other party
        shall bear all costs and expenses incurred by such other

                                       66

<PAGE>

        party in compelling arbitration of any dispute. Nothing contained herein
        shall be deemed to be a waiver by any party that is a bank of the
        protections afforded to it under 12 U.S.C. Section 91 or any similar
        applicable state law.

                (c)     No Waiver of Provisional Remedies, Self-Help and
        Foreclosure. The arbitration requirement does not limit the right of any
        party to (i) foreclose against real or personal property collateral;
        (ii) exercise self-help remedies relating to collateral or proceeds of
        collateral such as setoff or repossession; or (iii) obtain provisional
        or ancillary remedies such as replevin, injunctive relief, attachment or
        the appointment of a receiver, before during or after the pendency of
        any arbitration proceeding. This exclusion does not constitute a waiver
        of the right or obligation of any party to submit any dispute to
        arbitration or reference hereunder, including those arising from the
        exercise of the actions detailed in Sections (i), (ii) and (iii) of this
        paragraph.

                (d)     Arbitrator Qualifications and Powers. Any arbitration
        proceeding in which the amount in controversy is $5,000,000.00 or less
        will be decided by a single arbitrator selected according to the Rules,
        and who shall not render an award of greater than $5,000,000.00. Any
        dispute in which the amount in controversy exceeds $5,000,000.00 shall
        be decided by majority vote of a panel of three arbitrators; provided,
        however, that all three arbitrators must actively participate in all
        hearings and deliberations. The arbitrator will be a neutral attorney
        licensed in the State of Texas with a minimum of ten years experience in
        the substantive law applicable to the subject matter of the dispute to
        be arbitrated. The arbitrator will determine whether or not an issue is
        arbitratable and will give effect to the statutes of limitation in
        determining any claim. In any arbitration proceeding the arbitrator will
        decide (by documents only or with a hearing at the arbitrator's
        discretion) any pre-hearing motions which are similar to motions to
        dismiss for failure to state a claim or motions for summary
        adjudication. The arbitrator shall resolve all disputes in accordance
        with the substantive law of Texas and may grant any remedy or relief
        that a court of such state could order or grant within the scope hereof
        and such ancillary relief as is necessary to make effective any award.
        The arbitrator shall also have the power to award recovery of all costs
        and fees, to impose sanctions and to take such other action as the
        arbitrator deems necessary to the same extent a judge could pursuant to
        the Federal Rules of Civil Procedure, the Texas Rules of Civil Procedure
        or other applicable law. Judgment upon the award rendered by the
        arbitrator may be entered in any court having jurisdiction. The
        institution and maintenance of an action for judicial relief or pursuit
        of a provisional or ancillary remedy shall not constitute a waiver of
        the right of any party, including the plaintiff, to submit the
        controversy or claim to arbitration if any other party contests such
        action for judicial relief.

                (e)     Discovery. In any arbitration proceeding discovery will
        be permitted in accordance with the Rules. All discovery shall be
        expressly limited to matters directly relevant to the dispute being
        arbitrated and must be completed no later than twenty (20) days before
        the hearing date and within one hundred and eighty (180) days of the
        filing of the dispute with the AAA. Any requests for an extension of the
        discovery periods, or any discovery disputes, will be subject to final
        determination by the arbitrator upon a showing that the request for
        discovery is essential for the party's presentation and that no
        alternative means for obtaining information is available.

                (f)     Class Proceedings and Consolidations. The resolution of
        any dispute arising pursuant to the terms of this Agreement shall be
        determined by a separate arbitration proceeding and such dispute shall
        not be consolidated with other disputes or included in any class
        proceeding.

                (g)     Payment of Arbitration Costs and Fees. The arbitrator
        shall award all costs and expenses of the arbitration proceeding.

                                       67

<PAGE>

                (h)     Miscellaneous. To the maximum extent practicable, the
        AAA, the arbitrators and the parties shall take all action required to
        conclude any arbitration proceeding within one hundred and eighty (180)
        days of the filing of the dispute with the AAA. No arbitrator or other
        party to an arbitration proceeding may disclose the existence, content
        or results thereof, except for disclosures of information by a party
        required in the ordinary course of its business or by applicable law or
        regulation. If more than one agreement for arbitration by or between the
        parties potentially applies to a dispute, the arbitration provision most
        directly related to the Loan Documents or the subject matter of the
        dispute shall control. This arbitration provision shall survive
        termination, amendment or expiration of any of the Loan Documents or any
        relationship between the parties.
