             $20,000,000 SENIOR SECOND LIEN SECURED CREDIT AGREEMENT

         This $20,000,000 Senior Second Lien Secured Credit Agreement (this
"Agreement") is dated November 6, 2003, between PetroQuest Energy, L.L.C., a
Louisiana limited liability company, having its principal executive office and
place of business at 400 E. Kaliste Saloom Road, Suite 6000, Lafayette, LA 70508
("Borrower"); PetroQuest Energy, Inc., a Delaware corporation having its
principal executive office and place of business at 400 E. Kaliste Saloom Road,
Suite 6000, Lafayette, LA 70508 ("Guarantor"); each of the Lenders from time to
time party hereto; and Macquarie Americas Corp., a Delaware corporation, (in its
individual capacity, "MAC"), as administrative agent for the Lenders (in such
capacity, together with its successors in such capacity, the "Administrative
Agent").

                                   BACKGROUND:

         1.       Borrower desires to obtain a credit facility from Lenders for
the purpose of further developing the Properties (defined below). Lenders desire
to make available to Borrower a senior second lien secured term loan on a
non-revolving basis for those purposes under the terms and conditions of this
Agreement.

         2.       In connection with Lenders making available to Borrower the
financial accommodations described in this Agreement and subject to the other
terms of this Agreement and the Loan Documents (defined below), Borrower will
grant to the Administrative Agent, for the benefit of Lenders, a second-priority

Tranche of the Term Loan after the Availability Termination Date.

         Section 2.3 Advance Procedure. In connection with any Advance under the
Term Loan, Borrower will submit to the Administrative Agent a single written
Advance Request not later than 12:00 noon Houston, Texas time, at least three
(3) Business Days prior to the date on which the Advance is to be made;
provided, however, that Lenders shall not have any obligation to make any
Advances unless and until all of the conditions set forth in Sections 9.2, 9.3
and this Article II have been satisfied.

         Section 2.4 Term Notes. Borrower's obligation to repay the Term Loan
will be evidenced by Term Notes in favor of each Lender. The Advances made by
each Lender shall be evidenced by a single Term Note, dated, in the case of (i)
any Lender party hereto as of the date of this Agreement, or (ii) any Lender
that becomes a party hereto pursuant to an assignment, as of the effective date
of the assignment, payable to the order of such Lender in a principal amount
equal to its commitment as in effect on such date, and otherwise duly completed.
In the event that any Lender's commitment increases or decreases for any reason,
the Borrower shall deliver or cause to be delivered on the effective date of
such increase or decrease, a new Note payable to the order of such Lender in a
principal amount equal to its commitment after giving effect to such increase or
decrease, and otherwise duly completed. The date, amount, interest rate of each
Advance 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
Advances or affect the validity of such transfer by any Lender of its Note.

         Section 2.5 Interest.

                  (a)      The Advances comprising the Term Loan shall bear
interest at the Contract Rate on the outstanding borrowed and unpaid principal
amount of the Term Loan for the period commencing on the date of the initial
Advance until all Obligations are paid in full in accordance with this
Agreement. Upon the occurrence and during the continuation of an Event of
Default, the rate of interest applicable to the Notes will be equal to the
lesser of (i) the Highest Lawful Rate and (ii) four percent (4.0%) over the
interest rate otherwise applicable (the "Default

                                       21

Rate"). In addition, if any principal of or interest on any Advance or any fee
or other amount payable by Borrower or any Guarantor hereunder or under any
other Loan Document is not paid when due, whether at stated maturity, upon
acceleration or otherwise, such overdue amount shall bear interest, after as
well as before judgment, at a rate per annum equal to the Default Rate.

                  (b)      All interest will be computed on the basis of a year
comprised of 360 days. Interest will be due and payable in accordance with this
Section 2.5 in immediately available funds monthly in arrears on the Repayment
Date and in full on the Loan Termination Date.

                  (c)      Borrower shall pay to Lenders all outstanding

indemnify Lenders) on each Repayment Date.

                  (d)      The applicable interest rate under this Agreement

the Loan Documents, second to accrued interest on the Term Loan and third to
principal on the Term Loan. All interest on the outstanding principal balance of
the Term Loan from the Closing Date through October 31, 2003, will be due and
payable on November 15, 2003. On each subsequent Repayment Date, interest will
be due and payable on the outstanding principal balance of the Term Loan for the
immediately preceding calendar month.

proceeding by or before any court or Governmental Authority or to any remedial
obligations under Environmental Laws;

                  (c)      All notices, permits, licenses or similar

not the subject of any existing, pending or threatened action, investigation or

compliance with the OPA requirements during the term of this Agreement; and

                  (g)      Neither the Borrower nor any of its Affiliates has

         Section 4.17 Operating Permits and Licenses. Borrower and its
Subsidiaries have fulfilled all requirements for obtaining and have obtained and
maintained all licenses, permits, operating authorities and other authorizations
necessary for the conduct of the business of the Borrower and its Subsidiaries
or for Borrower or its Subsidiaries to operate or maintain each of the
Properties which it operates, and Borrower is and will be fully qualified to own
and hold such Properties and to exercise rights under all leases, contracts or
other documents governing the operation or maintenance of the Properties. All of
the Personal Property and Properties of the Borrower or its Subsidiaries which

condition and are maintained in accordance with prudent business standards.
There are no pending fees, assessments or penalties relating to the permits,
licenses and operating authorities. The continuation, validity and effectiveness
of each license, permit and other authorization are not and will in no way be
adversely affected by the transactions contemplated by this Agreement or the
Security Documents. Neither Borrower nor any Subsidiary is in breach of, or in
default under the terms of, and has not engaged in any activity which would
cause revocation or suspension of, any such licenses, permits or authorizations
and no action or proceeding looking to or contemplating the revocation or
suspension of any of them is pending or, to the best of Borrower's knowledge,
threatened against Borrower. Neither Borrower nor any Subsidiary is in violation
in any material respect of any law, ordinance, administrative or governmental
rule or regulation or court decree relating to any of the Properties or
otherwise applicable to Borrower, any Subsidiary or any Operator. No suspension
of production on the Properties is in effect which could reasonably be expected
to have a Material Adverse Effect.

         Section 4.18 Maintenance of Properties. Except for such acts or
failures to act as could not be reasonably expected to have a Material Adverse
Effect, the Properties (and Properties

                                       31

workmanlike manner and in conformity with all government requirements and in
conformity with the provisions of all leases, subleases or other contracts

any overproduction (whether or not the same was permissible at the time) and (b)
none of the wells comprising a part of the Properties (or Properties unitized
therewith) is deviated from the vertical more than the maximum permitted by
government requirements, and such wells are, in fact, bottomed under and are
producing from, and the well bores are wholly within, the Properties (or in the
case of wells located on Properties unitized therewith, such unitized
Properties). All pipelines, wells, gas processing plants, platforms and other
material improvements, fixtures and equipment owned in whole or in part by the
Borrower or its Subsidiaries that are necessary to conduct normal operations are
being maintained in a state adequate to conduct normal operations, and with
respect to such of the foregoing which are operated by the Borrower or its
Subsidiaries, in a manner consistent with past practices.

         Section 4.19 Defaults. Neither Borrower nor any Subsidiary and, to
Borrower's knowledge, any Operator are in violation of, or in default under, any

its property is bound. All Wells are, in all material respects, operated in
compliance with all applicable rules, regulations, permits, judgments, orders
and decrees of any court or the federal and state regulatory authorities having
jurisdiction over Borrower, any Subsidiary or any Operator or any of the Wells.

         Section 4.20 Contingent Liabilities. Neither Borrower nor any

in connection with the Security Documents.

or other limitation on Lenders' right to obtain or exercise its security
interests in the Equipment, including the right to foreclose on and sell the

Agreement, all insurance proceeds received by Lender shall be retained by Lender
at its option, for application to the payment of such portion of the Obligations
or as Lender may determine in its reasonable discretion or shall be applied to
repair any such insurable loss or damage; and

promptly notify Administrative Agent thereof. If Borrower so notifies
Administrative Agent, Borrower acknowledges that one or more of the Lenders may
treat the

with the terms of the relevant contract and are not having deliveries curtailed
substantially below the subject Property's delivery capacity), no material
agreements exist which are not cancelable on 60 days notice or less without
penalty or detriment for the sale of production from the Borrower's or any

(including, without limitation, any Hedging Agreement or Swap Agreement) to
which Borrower is a party;

         Section 5.10 Reserve Reports.

                  (a)      Timing of Reports. Beginning January 1, 2004 and
continuing semi-annually throughout the term of this Agreement, Borrower shall,
at its sole expense, cause to be prepared by the Engineers and delivered to
Lenders an engineering reserve report (the "Reserve Report") relating to the
Properties. The Reserve Reports will set forth, without limitation, the
projected recoverable reserves attributable to the Properties, the Working
Interests and Net Revenue Interests of Borrower. Borrower shall deliver each
Reserve Report to Lenders within sixty (60) days of its effective date. The
initial Reserve Report effective date shall be January 1, 2004. So long as no
Default has occurred and continues, the "mid-year" Reserve Report may be
prepared by Borrower's internal engineers; however, such Reserve Report must be
acceptable to Lender in its reasonable discretion.

                  (b)      Preparation of Reports. The Reserve Report will be
prepared in accordance with the following assumptions:

                           (i)      reserves shall be adjusted for cumulative
production since the effective date of the most recent Reserve Report;

                           prices provided to Borrower by Administrative Agent
                           for that year for Natural Gas as reflected in the New
                           York Mercantile Exchange as of the settlement of the
                           last trading day for the contract month coincident
                           with the effective date of the Reserve Report (as
                           adjusted for appropriate quality, transportation and
                           location differentials approved by Lenders), using
                           price escalators or de-escalators existing in the
                           market as determined by Lenders at the time the

                           fide contract or with respect to which the price has

                           prices provided to Borrower by Administrative Agent
                           for that year for Crude Oil as reflected in the New

                           with the effective date of the Reserve Report (as
                           adjusted for appropriate quality, transportation and
                           location differentials approved by Lenders), using

                           fide contract or for which the price has been hedged
                           pursuant to any New York Mercantile Exchange contract
                           or bona fide price swap agreement or arrangement, the
                           purchase price will be the fixed price (as adjusted
                           for appropriate quality, transportation and location
                           differentials approved by Lenders) for the volumes
                           indicated in the contract, agreement or arrangement.

         Borrower covenants and agrees that, so long as there are any

interest owners in the Properties which it operates;

                  (b)      duly observe and conform in all material respects
with all laws, rules and regulations made by any governmental authority, and all
valid requirements of any regulatory body which may acquire jurisdiction, which

including, without limitation, compliance with all obligations under the
Environmental and Safety Regulations;

                  (c)      operate or cause each Property to be operated

applicable federal law or under any state, local or municipal law, statute
(including, without limitation, Hazardous Substance Laws), ordinance, rule or
regulation designed to protect the environment or relating to the disposition,
generation or transportation of hazardous waste, which would constitute a lien
or charge on any property of Borrower prior in right to that of Lenders. If any
claim of prior lien or charge is made or any similar obligation arises, Borrower
will, at its own expense, (a) immediately cure or cause a third party to
immediately cure the same and (b) indemnify and hold harmless Lenders and its
officers, directors, agents and employees from any related liability,
responsibility or obligation in connection with any cleanup or other liability
as successor, secured party or otherwise (regardless of whether or not Lenders

party under this Agreement, the Security Documents or by operation of law;

                  (d)      comply with, and use all commercially reasonable

things reasonably necessary to preserve and keep in good repair, working order
and efficiency all of its Properties including, without limitation, all
equipment, machinery and facilities, and from time to time will make all the
reasonably necessary repairs, renewals and replacements so that at all times the
state and condition of its Properties will be fully preserved and maintained,

producing in paying quantities;

                  (f)      comply with ERISA and all applicable rules and
regulations; and

                                       44

any forfeiture thereof or a default thereunder, except to the extent a portion
of such Properties is no longer capable of producing in paying quantities.

                  (a)      The Borrower shall at its expense: (i) comply, and
shall cause the Properties and operations to comply, with all applicable
Environmental Laws, the breach of which could be reasonably expected to have a
Material Adverse Effect; (ii) not dispose of or otherwise release, any oil, oil
and gas waste, hazardous substance, or solid waste on, under, about or from any
of the Properties or any other property to the extent caused by the Borrower's
or any Subsidiaries' operations except in compliance with applicable
Environmental Laws, the disposal or release of which could reasonably be
expected to have a Material Adverse Effect; (iii) timely obtain or file all
notices, permits, licenses, exemptions, approvals, registrations or other
authorizations, if any, required under applicable Environmental Laws to be
obtained or filed in connection with the operation or use of the Borrower's
Properties, which failure to obtain or file could reasonably be expected to have
a Material Adverse Effect; (iv) promptly commence and diligently prosecute to

connection with the actual or suspected past, present or future disposal or
other release of any oil, oil and gas waste, hazardous substance or solid waste

Subsidiary or the Properties of which the Borrower has knowledge in connection
with any Environmental Laws (excluding routine testing and corrective action) if
the Borrower reasonably anticipates that such action will result in liability
(whether individually or in the aggregate) in excess of five hundred thousand
dollars ($500,000), not fully covered by insurance, subject to normal
deductibles.

                  (b)      the occurrence of any condition or event which has

dollars ($500,000) with respect to any of the Collateral excluding market

upon its request copies of all contracts, statements, invoices, notices,

         Section 6.10 Consultants. Borrower shall accord to Lenders the right,
with prior written notice to Borrower (except upon the occurrence and during the
continuation of an Event of Default, in which case no prior written notice is
required), from time to time, to select and retain consultants, including
engineers and public accountants, to advise Lenders as to technical and
financial matters pertaining to Borrower's operations relating to the Properties
and Borrower's financial records. Except as otherwise provided in this
Agreement, the reasonable fees and costs charged by Lenders' consultants will be
paid by Borrower. Borrower shall allow Lenders' consultants access during normal
business hours to the Properties and all other facilities owned, operated or
used by Borrower in connection with the Properties or the conduct of Borrower's
business and to Borrower's records (financial or otherwise) relating to the
operation of the Properties. The access granted to Lenders and its consultants
under this Section 6.10 will not unreasonably disrupt the business of Borrower
or the operation of the Properties.

         Section 6.11 Creditors. Borrower shall promptly, upon Lenders' request,

fails to make any payment (other than a contested payment) in accordance with
required terms to lessors, suppliers, vendors, owners of Royalty Interests,
third-party Working Interest owners, tax authorities or others relating to the
Properties, including, without limitation, owners or holders of overriding
royalty interests, net profit interests, production payments, or any other liens
or burdens on or relating to the Properties, where non-payment would create any
lien rights against any item of Collateral or otherwise interfere with or
jeopardize performance by Borrower under this Agreement. Upon receipt of a
notice of non-payment from Borrower, Lenders may, but need not, make in its
reasonable discretion, any payments or agree to pay any persons as are required
to enable Borrower to complete performance under this Agreement or to protect
the interests of Lenders in production from or allocable to Borrower's Net
Revenue Interest in the Properties or other Collateral, and those payments will
be immediately reimbursed to Lenders by Borrower on demand. Borrower's
obligation to reimburse Lenders for any payments will be secured by the security
interests and the liens granted under the Security Documents.

         Section 6.12 Inspection. Borrower shall, so long as any Obligation
remains owing to Lenders or any Collateral remains located at any of the
Properties or other facilities owned or leased by Borrower, accord Lenders or
its agents full and unrestricted access (at Lenders' risk) upon the giving of
reasonable notice under the circumstances (subject to reasonable safety
restrictions and in accordance with prudent operator standards) during normal
business hours to the Properties and such other facilities to permit Lenders or
its agents to, among other things, witness drilling, workovers and other field
activities and inspect or take delivery of production. Borrower shall give
Lenders or its agents due notice of drilling, workovers and other field
activities to permit Lenders to exercise its rights under this Section 6.12. The
access granted to

                                       47

<PAGE>

Lenders under this Section 6.12 will not unreasonably disrupt the business of
Borrower or the operation of the Properties.

         Section 6.13 Environmental Opinion. Borrower shall, upon Lenders'
reasonable request, obtain opinions from counsel or other consultants reasonably
satisfactory to Lenders that Borrower has all permits, licenses and other
approvals required by the EPA and other applicable Governmental Authorities, and
the current and planned operations of the Properties are in compliance with all
applicable laws and requirements.

         Section 6.14 Operators. Borrower shall, in the event of a failure by
any Operator to perform any obligations under the respective Operating Agreement
or upon the occurrence of a Default under this Agreement which is not cured
within the applicable cure period:

                  (a)      immediately, upon the request of Lenders, vote or
cause the applicable Subsidiary to vote to remove an Operator or commence any
proceedings necessary under the applicable Operating Agreement to remove an
Operator or assign to Lenders its right to vote to remove the Operator with
respect to the Properties; provided, however, that Borrower and the Lenders
agree and acknowledge that the removal of an Operator under this Section 6.14 is
subject to the consent of the Senior Lender pursuant to Section 6.33 of the
Senior Credit Facility,

                  (b)      seek indemnification or damages from the Operator and
its successors or assigns for any loss or liability incurred by Borrower or any
Subsidiary,

                  (c)      deliver or use all commercially reasonable efforts to
cause each Operator to deliver to any successor Operator all books, agreements,
contracts, papers, records (including but not limited to royalty payment
records, computerized tapes and other royalty payment information), division
orders, farm-in and farmout agreements, and all other records, contracts,
agreements, papers or documents, written, printed or computerized, which may be
pertinent in any way to the operations to be conducted by the successor Operator
or which may have been conducted by the former Operator,

                  (d)      cooperate, and use all commercially reasonable
efforts to cause each Operator to fully cooperate with the successor Operator to
ensure that the Leases are not terminated or the value of the Properties
diminished by virtue of the resignation or removal, and

                  (e)      take all other actions and use all commercially
reasonable efforts to cause each Operator to take all other actions necessary to
ensure an orderly transition of all operations to the successor Operator.
Borrower shall promptly reimburse Lenders for any payments made pursuant to this
Section 6.14. The rights and remedies of Lenders under this Section 6.14 are in
addition to any other rights or remedies available under Article XI or elsewhere
in this Agreement.

         Section 6.15 Purchasers of Hydrocarbons. Borrower shall, in the event
that any Purchaser of Hydrocarbons is, in Lenders' reasonable judgment, not
creditworthy, upon the request of Lenders, (i) cause the Purchaser to provide
one or more letters of credit, in form and

                                       48

<PAGE>

substance and from a bank satisfactory to Lenders in connection with its
purchase of Hydrocarbons from the Properties, (ii) sell Hydrocarbons only to
Purchasers who are creditworthy in Lenders' reasonable judgment or who prepay,
or (iii) exercise its right to take the Hydrocarbons in kind and sell to
Purchasers of Hydrocarbons who are creditworthy in Lenders' reasonable judgment.

         Section 6.16 Access to Officers, Employees and Agents. Borrower shall
allow Lenders reasonable access to appropriate officers, employees and agents of
Borrower and its Subsidiaries to discuss the affairs, finances and accounts of
Borrower and its Subsidiaries at all reasonable times and as often as Lenders
may reasonably request.

         Section 6.17 Hedging Hydrocarbon Production.

                  (a)      Hedges at Closing. At or prior to Closing, Borrower
shall enter into an energy price hedging or swap pursuant to a Hedging Agreement
with Senior Lender or other Person acceptable to MAC or a Swap Agreement (in
either case, in form and substance satisfactory to Lenders in their sole and
absolute discretion) such that up to seventy percent (70%) of the volume of PDP
Reserves scheduled to be produced for the period commencing on the Closing Date
through and including the Maturity Date (based upon the most recent Reserve
Report) are dedicated to the Hedging Agreement or other price risk management
program approved by Lenders.

                  (b)      Additional Hedges. Beginning six (6) months after
Closing and continuing each six (6) months thereafter (upon receipt of an
updated Reserve Report) or more frequently if Borrower and the Lenders so agree,
Lenders may require Borrower to enter into one or more additional Hydrocarbon
Hedging Agreement such that up to sixty-five percent (65%) of the incremental
PDP Reserves identified in the most current Reserve Report are dedicated to the
Hedging Agreement or other price risk management program approved by Lenders in
their sole and absolute discretion.

                  (c)      Miscellaneous. The minimum average price for all PDP
Reserves subject to the Swap Agreement at Closing shall, for the periods from
the Closing Date through the Maturity Date, be as described on Schedule 6.17.
Lenders may require that Borrower's hedging program be extended beyond the
Maturity Date if any of the Obligations remain outstanding as of that date, and
if so required, Borrower shall enter into such additional energy price hedging
arrangements necessary to comply with Lender's request.

                  (d)      MAC As Counterparty. At least forty percent (40%) of
the total future hedged Hydrocarbon volumes will be hedged under a Swap
Agreement with MAC with a maximum credit margin of twelve and one-half cents
($0.125) per mmbtu of natural gas and forty cents ($0.40) per barrel of crude
oil on a swap equivalent basis or as otherwise agreed by Borrower and MAC.
Notwithstanding the previous sentence, however, nothing in this Section 6.17(d)
will be construed to require Borrower to enter into any hedging transaction with
MAC on terms and conditions that are not reasonably competitive with the terms
and conditions on which comparable counterparties are both willing and able to
enter into like hedge

                                       49

<PAGE>

transactions at the time of such transaction (the "Competing Hedge Terms").
Borrower shall notify MAC in writing prior to entering into any hedge
transaction with MAC that Borrower reasonably believes is subject to terms or
conditions that are not reasonably competitive with Competing Hedge Terms.
Promptly following MAC's receipt of a written notice from Borrower pursuant to
the immediately preceding sentence, MAC and Borrower will confer and, if
necessary, attempt to identify a mutually acceptable amendment to this Section
6.17(d).

                  (e)      Unless otherwise approved by Lenders, the sole
counterparty to any Hedging Agreement with Borrower shall be MAC or its
Affiliates or BankOne, N.A. or its Affiliates.

         Section 6.18 Use of Proceeds. Borrower shall use all amounts Advanced
under the Term Loan only as described in this Agreement and as approved in
writing by the Lenders in connection with each Advance.

         Section 6.19 Bonds. Borrower shall, and shall cause each Subsidiary to,
maintain in full force and effect all federal and state qualifications, bonds
and approvals necessary to own and operate the Properties, and deliver to
Lenders certificates evidencing any bonds and copies of any bonds in place
(including renewals).

         Section 6.20 Minimum Payments. Borrower shall pay to Lenders all
outstanding interest calculated at the rate specified in this Agreement on all
Obligations (including Obligations which are for fees or to reimburse or
indemnify Lenders) on each Repayment Date.

         Section 6.21 Post-Closing Title Opinions. Within sixty (60) days
following Closing, Borrower will deliver to Lenders post-closing title opinions
(or other title information acceptable to Lenders) in form and substance
acceptable to Lenders covering not less than 81% of the Proved Reserves
Properties showing a Mortgage Lien in favor of the Administrative Agent for the
ratable benefit of the Lenders subject only to Permitted Encumbrances.
Additionally, as requested by Lenders, Borrower will provide Lenders with new,
updated or supplemental title opinions (or other title information acceptable to
Lenders) on Proved Reserves Properties that are added as Collateral.

         Section 6.22 Continuing Enterprise. Borrower shall, and shall cause
each Subsidiary to, continue to conduct its operations on such a scale and in
such a manner as is necessary to (a) perform its obligations under this
Agreement and the Basic Documents, and (b) preserve its rights to the Properties
and its rights under the Basic Documents.

         Section 6.23 Venue for Debtor Relief Proceedings. If Borrower
voluntarily commences any proceeding under any Debtor Relief Law, Borrower shall
initiate and maintain the proceeding in a court within the Southern District of
Texas.

         Section 6.24 Access to Seismic and Geophysical Data. Borrower and
Guarantor shall provide Lenders and their respective engineering consultants
with access to all engineering, seismic, geological and geophysical data,
studies and evaluations which Borrower or Guarantor

                                       50

<PAGE>

possess or to which Borrower or Guarantor has access which relate to the
Properties. Lenders will, upon reasonable notice to Borrower or Guarantor as
applicable, have access to these records during regular business hours;
provided, however, to the extent the information to be made available to Lenders
under this Section 6.24 is subject to a confidentiality agreement, Borrower or
Guarantor, as applicable, may require Lenders to execute and deliver to it a
mutually acceptable confidentiality agreement prior to being allowed access to
the confidential information.

         Section 6.25 Liens on Collateral. The Borrower will at all times cause
at least 90% of the PDP Properties to be subject to a perfected Mortgage Lien in
favor of or for the benefit of the Lenders pursuant to the Security Documents
subject only to the Senior Liens and Permitted Encumbrances.

         Section 6.26 Certain Financial Covenants. Borrower shall, at all times
while the Obligations are outstanding:

                  (a)      maintain an Interest Coverage Ratio of 2.50 to 1.00;

                  (b)      maintain a Current Ratio of 1.30 to 1.00 until

to 1.00;

                  (d)      maintain a Developed Reserve Adjusted Present Value
Ratio of 2.00 to 1.00; and

                  (e)      maintain all financial covenants set out in the
Senior Credit Facility.

         Section 6.27 Additional Guarantors. Notify Administrative Agent at the
time that any Person becomes a Subsidiary, and promptly thereafter (and in any
event within 30 days), cause such Person to (a) become a Guarantor by executing
and delivering to Administrative Agent for the benefit of Lenders a counterpart
of the Guaranty Agreements or such other document as Administrative Agent shall
deem appropriate for such purpose, and (b) deliver to Administrative Agent
documents of the types referred to in clauses (iii) and (iv) of Section 9.2(h)
and favorable opinions of counsel to such Person (which shall cover, among other
things, the legality, validity, binding effect and enforceability of the
documentation referred to in clause (a)), all in form, content and scope
reasonably satisfactory to Administrative Agent.

         Section 6.28 Collateral Records. Borrower agrees to execute and deliver
promptly, and to cause each Subsidiary to execute and deliver promptly, to
Administrative Agent, from time to time, solely for Administrative Agent's
convenience in maintaining a record of the Collateral, such written statements
and schedules as Administrative Agent may reasonably require designating,
identifying or describing the Collateral. The failure by Borrower or any other
Person, however, to promptly give Administrative Agent such statements or
schedules shall not

                                       51

<PAGE>

affect, diminish, modify or otherwise limit the Liens on the Collateral granted
pursuant to the Collateral Documents.

                                  ARTICLE VII.
                               Negative Covenants

Agreement or a Swap Agreement, and unless Lenders has previously consented in
writing to Borrower's non-compliance, Borrower will comply with the following

                           (vii)    endorsements of negotiable instruments for

$500,000 related to purchase money financing;

         Section 7.3 Guaranties. Borrower shall not assume, guaranty or endorse
or otherwise become directly or contingently liable for any liability of any
other Person except as provided in the Senior Credit Facility and except for the

portion of the stock, securities or assets of any other Person, (ii) suffer any
Change of Control or (iii) merge into or consolidate with any other Person;
provided, however, that Guarantor, Borrower or any Subsidiary may acquire by
purchase, merger or otherwise, additional Hydrocarbon properties or the capital
stock or interests of any Person whose business is the ownership and operation
of Hydrocarbon properties to the extent such transaction does not result in a
Change of Control;

                                       53

<PAGE>

                  (b)      enter into any business which is, in Lenders'
reasonable judgment, significantly different from its present business;

to joint development agreements, participation agreements, farmout agreements,

agreements;

                           (iii)    the sale or transfer of equipment that is no
longer necessary for their business or is replaced by equipment of at least

                           (iv)     during consecutive twelve month period,
sales or other dispositions of Hydrocarbon properties in the ordinary course
that will not exceed $1,000,000 in the aggregate, and that will not materially
impair or diminish the value of the Collateral or the Borrower's financial
condition;

                           upon the written request of Borrower setting forth in
reasonable detail the transfer, sale or conveyance of assets in a transaction
permitted by this Section 7.4(c), Administrative Agent will execute and deliver
to Borrower such documentation as is reasonably necessary in the opinion of
Administrative Agent and its counsel to release the Lien of Lenders on the
assets transferred, sold or conveyed;

                  (d)      cancel any claim or Debt during the term of the Term
Loan, except for consideration and in the ordinary course of its business;

                  (e)      prepay any Debt other than Obligations owing to
Lenders hereunder and obligations owing under the Senior Credit Facility;

                  (f)      cause or suffer to exist a default under any lease,
mortgage, deed of trust or lien on real estate owned or leased by Borrower;

                  (g)      except as permitted in Section 7.1(ix), make any loan
or advance or extend any credit during the term of the Term Loan (except in the
ordinary course of business) to any Person, whether or not an Affiliate of
Borrower;

commercial production, or the release or abandonment of all or any part of
Borrower's Working Interest or Net Revenue Interest in any of the Properties
capable of commercial production, or release or abandon all or any portion of
the Properties except in accordance with prudent operator standards; (ii)
Borrower's Net Revenue Interest in the Properties to be developed, maintained or
operated in a manner less favorable than prudent operator standards; and (iii)
any material alterations in the Basic Documents;

                  (k)      except in the ordinary course of business and as
permitted under this Agreement, enter into any new agreement or contract with
any Person relating to or affecting any of the Properties that could be material
in the context of any particular Lease;

                  (l)      make or commit to make any expenditure in connection
with any project or activity not included in the then current Annual Operating
Budget which has been approved in writing by Lenders; or

their sole and absolute discretion, make or commit to make any expenditures in
excess of the aggregate expenditures included in the then current Annual
Operating Budget which has been approved in writing by Lenders. For the
avoidance of doubt, the Annual Operating Budget sets forth 115% of the aggregate

encumbrances permitted under Section 6.15 of the Senior Credit Facility;

                           (iii)    the Permitted Encumbrances; and

Subsidiary shall create any direct or indirect subsidiary or divest itself of

remove all Hazardous Materials Released to the full extent necessary to comply
with the requirements of all applicable Environmental and Safety Regulations.

         Section 7.9 Dividends and Distributions. Neither Guarantor nor Borrower
will, nor will they permit any Subsidiary to, declare or pay any dividends or

dollars ($25,000,000.00); provided, however, for the purpose of computing the
limitation under this Section 7.11, "committed but undrawn amounts" under this

                           Further Rights of Lenders

         Section 8.1 Delivery of Additional Documents. Until the Obligations are
repaid in full, Borrower, at its own expense, shall do all things and shall
deliver all instruments requested by Lenders to protect or perfect any security
interest, mortgage or lien granted or created under this Agreement or any of the
Security Documents. Lenders may examine, inspect and copy or make extracts from
all books and records of Borrower at any time during regular business hours upon
prior notice to Borrower. Borrower authorizes Lenders to execute alone any other
instruments that Lenders may require to perfect, protect or establish any lien
or security interest under this Agreement or any of the Security Documents and
further authorizes Lenders to sign Borrower's name on any of those instruments.
Upon the occurrence of an Event of Default, Borrower authorizes Lenders to
appoint any Person or Persons as Lenders may designate as its agent and
attorney-in-fact to endorse the name of Borrower on any checks, notes, drafts or
other forms of payment or security that may come into the possession of either
Lenders or any Affiliate of Lenders, to sign Borrower's name on invoices or
bills of lading, drafts against customers, notices of assignment, verifications
and schedules and, generally, to do all things necessary to carry out this
Agreement and the Security Documents. The powers granted in this Section 8.1 are
coupled with an interest and are, therefore, irrevocable. Neither Lenders nor
any agent or attorney-in-fact will be liable to any Person for any act or
omission, error in judgment or mistake of law that is not malicious or grossly
negligent. Upon payment and performance of all Obligations of Borrower to
Lenders, this power of attorney will become null and void.

         Section 8.2 Payments by Lenders. If Borrower fails to purchase or
maintain insurance in accordance with this Agreement, or to pay any tax,
assessment, government charge or levy in accordance with this Agreement, or in
the event that any prohibited lien, encumbrance or security interest is not
discharged in accordance with this Agreement, or in the event that Borrower
fails to perform or comply with any other covenant, promise or Obligation under
any Loan Document, Lenders may, but will not be required to, perform, pay,
satisfy, discharge or bond the same for the account of Borrower, and all amounts
paid by Lenders, including reasonable attorneys' fees and disbursements, will be
deemed to be additional Obligations owing by Borrower to Lenders under this
Agreement; provided, however, that Lenders will not make any payments on behalf
of Borrower without providing Borrower prior written notice of at least three
(3) Business Days.

         Section 8.3 Payment of Taxes, Etc. Borrower and each Subsidiary shall
pay all costs to be paid on taxes, assessments, governmental charges or private
encumbrances levied, assessed, imposed or payable upon or with respect to any of
the Collateral.

         Section 8.4 Possession. Upon the occurrence and during the continuation
of an Event of Default, Lenders may (i) enter Borrower's or any Subsidiaries'
premises at any time, and (ii) until it completes the enforcement of its rights
in the Equipment or other Collateral subject to its security interest or lien
under the Security Documents and the sale or other disposition of any property
subject to those documents, take possession of those premises without charge,
rent or payment, or place custodians in control any of the premises, remain on
and use the premises and any of Borrower's or any Subsidiaries' Equipment and
other Collateral for the purpose of completing any work in progress, preparing
any Collateral for disposition or collecting any Collateral.

                  (a)      BORROWER WILL, TO THE FULLEST EXTENT PERMITTED BY

                               Remedies of Lenders

         Section 11.1 Remedies. Upon the occurrence of any Event of Default
other than under Sections 10.1(c) or 10.1(d), Lenders shall, by notice to
Borrower, take either or both of the following actions, at the same or different
times, following two (2) Business Days' prior written notice: (i) terminate the
commitments and thereupon the commitments shall terminate immediately and (ii)
declare the Term Notes and the Term Loan due and payable in whole (or in part,
in which case any principal not so declared to be due and payable may thereafter
be declared to be due and payable), and thereupon the principal of the Term Loan
so declared to be due and payable, together with accrued interest thereon and
all fees and other obligations of the Borrower and the Guarantor accrued
hereunder and under the Term Notes and the other Loan Documents, shall become
due and payable immediately, without presentment, demand, protest, notice of
intent to accelerate, notice of acceleration or other notice of any kind, all of
which are hereby waived by the Borrower and the Guarantor. Upon the occurrence
of an Event of Default described in Section 10.1(c) or Section 10.1(d), the
commitments shall automatically terminate and the Term Notes and the principal
of the Term Loan then outstanding, together with accrued interest thereon and
all fees and the other obligations of the Borrower and the Guarantor accrued
hereunder and under the Term Notes and the other Loan Documents, shall
automatically become due and payable, without presentment, demand, protest or
other notice of any kind, all of which are hereby waived by the Borrower and the
Guarantor. Upon a termination of commitments following an Event of Default,
Lenders will have, in addition to all of its other rights arising under any of
the Loan Documents or by operation of law or otherwise (which rights shall be
cumulative), all of the rights and remedies of a secured party under the Uniform
Commercial Code and will have the right to enter upon any premises where the
Collateral is kept and peacefully retake possession.

         Section 11.2 Collateral. Lenders will have no obligation to preserve
rights to any Collateral against prior parties or to proceed first against any
Collateral or to marshal any Collateral of any kind for the benefit of any other
creditor of Borrower or any other Person. Borrower grants to Lenders a license
or other right to use, without charge, Borrower's labels,

                                       70

<PAGE>

patents, copyrights, rights of use of any name, trade secrets, trade names,
trademarks and advertising matter, or any property of a similar nature related
to the Collateral and necessary or convenient in correction with Lenders
completing production of, advertising for sale and selling any Collateral, and
Borrower's rights under all licenses and any franchise, sales or distribution
agreements will inure to Lenders' benefit.

         Section 11.3 Costs and Expenses. Borrower shall pay all costs and
expenses of amending, administering, implementing, perfecting, collecting,
defending, declaring and enforcing Lenders' rights, security interests in the
Collateral under this Agreement or any Security Document or other instrument or
agreement delivered in connection with any of the Loan Documents, including
searches and filings at all times, and Lenders' attorneys' fees (regardless of
whether any litigation is commenced or default is declared and regardless of
tribunal or jurisdiction).

         Section 11.4 Set-Off Rights. Upon the occurrence and during the
continuation of an Event of Default, Lenders or the Administrative Agent on
behalf of the Lenders will have the right, at any time and from time to time, to
set-off and apply against the Obligations, in any manner Lenders may determine,
any and all deposits (general or special, time or demand, provisional or final)
or other amounts at any time credited by or owing from Lenders or any depositary
to Borrower whether or not the Obligations are then due; provided, however, that
this sentence will not apply to any amounts owing to third-party Working
Interest and Royalty Interest previously identified in writing to Lenders.
Lenders will provide notice to Borrower not later than three (3) days following
the application of any funds under this Section 11.4. As further security for
the Obligations, Borrower grants to Lenders a security interest in and lien on
all money, instruments, and other property of Borrower now or at any time held
by Lenders, including property held in safekeeping. In addition to Lenders'
right of set-off and as further security for the Obligations, Borrower grants to
Lenders a security interest in and lien on all deposits (general or special,
time or demand, provisional or final) and other accounts of Borrower now or at
any time on deposit with or held by Lenders or any depositary together with all
other amounts at any time credited by or owing from Lenders or any depositary to
Borrower. The rights and remedies of Lenders under this Section 11.4 are in
addition to other rights and remedies (including other rights of set-off) that
Lenders may have.

         Section 11.5 Rights Under Operating Agreements. Upon the occurrence and
during the continuation of an Event of Default, Lenders will have the right to
exercise Borrower's rights under the Operating Agreements, including the right
to remove and replace the Operator, with or without cause.

                                  ARTICLE XII.
                              Administrative Agent

         Section 12.1 Appointment and Authorization of Administrative Agent.
Each Lender hereby irrevocably appoints, designates and authorizes the
Administrative Agent to act as its agent under the Agreement and Loan Documents
and to take such action on its behalf under the provisions of this Agreement and
each other Loan Document and to exercise such powers and

                                       71

<PAGE>

perform such duties as are expressly delegated to it by the terms of this
Agreement, or any other Loan Document, together with such powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any Loan Document, the Administrative Agent
shall not have any duties or responsibilities, except those expressly set out
herein, nor shall the Administrative Agent have or be deemed to have any
fiduciary relationship with any Lender or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement, or any other Loan Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "Administrative Agent" herein and in the Loan Documents with
reference to the Administrative Agent is not intended to connote any fiduciary
or other implied (or express) obligations arising under agency doctrine of any
applicable Law. Instead, such term is used merely as a matter of market custom,
and is intended to create or reflect only an Administrative relationship between
independent contracting parties.

         Section 12.2 Delegation of Duties. The Administrative Agent may execute
any of its duties under this Agreement, or any other Loan Document by or through
agents, employees or attorneys-in-fact and shall be entitled to advice of
counsel and other consultants or experts concerning all matters pertaining to
such duties. The Administrative Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects in the
absence of gross negligence or willful misconduct on the part of the
Administrative Agent.

         Section 12.3 Liability of Administrative Agent. No Administrative
Agent-Related Person shall (a) be liable for any action taken or omitted to be
taken by any of them under or in connection with this Agreement, or any other
Loan Document or the transactions contemplated hereby (except for its own gross
negligence or willful misconduct in connection with its duties expressly set out
herein), or (b) be responsible in any manner to any Lender or participant for
any recital, statement, representation or warranty made by Borrower or any
officer thereof, contained in the Agreement or in any other Loan Document, or in
any certificate, report, statement or other document referred to or provided for
in, or received by the Administrative Agent under or in connection with, this
Agreement, or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement, or any other Loan
Document, or for any failure of Borrower or any other party to any Loan Document
to perform its obligations hereunder or thereunder. No Administrative
Agent-Related Person shall be under any obligation to any Lender or participant
to ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement, or any other Loan
Document, or to inspect the properties, books or records of Borrower or any
Affiliate thereof.

         Section 12.4 Reliance by Administrative Agent.

                  (a)      The Administrative Agent shall be entitled to rely,
and shall be fully protected in relying, upon any writing, communication,
signature, resolution, representation, notice, consent, certificate, affidavit,
letter, telegram, facsimile, telex or telephone message, electronic mail
message, statement or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons, and upon advice and statements of legal counsel (including counsel
to Borrower), independent

                                       72

<PAGE>

accountants and other experts selected by the Administrative Agent. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under any Loan Document unless it shall first receive such advice or
concurrence of the Required Lenders as it deems appropriate and, if it so
requests, it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting, under
this Agreement, or any other Loan Document in accordance with a request or
consent of the Required Lenders (or such greater number of Lenders as may be
expressly required hereby in any instance) and such request and any action taken
or failure to act pursuant thereto shall be binding upon all the Lenders.

                  (b)      For purposes of determining compliance with the
conditions specified in Article IX, each Lender shall be deemed to have
consented to, approved or accepted or to be satisfied with, each document or
other matter required thereunder to be consented to or approved by or acceptable
or satisfactory to a Lender unless the Administrative Agent shall have received
notice from such Lender prior to the Closing Date or Advance date, as
applicable, specifying its objection thereto.

         Section 12.5 Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default, except with respect to defaults in the payment of principal, interest
and fees required to be paid to the Administrative Agent for the account of the
Lenders, unless the Administrative Agent shall have received written notice from
a Lender or the Borrower referring to the Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default." The
Administrative Agent will notify the Lenders of its receipt of any such notice.
The Administrative Agent shall take such action with respect to such Default or
Event of Default as may be directed by the Required Lenders in accordance with
Article XI of the Agreement; provided that unless and until the Administrative
Agent has received any such direction, the Administrative Agent may (but shall
not be obligated to) take such action, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable or in the
best interest of the Lenders.

         Section 12.6 Credit Decision; Disclosure of Information by
Administrative Agent. Each Lender acknowledges that no Administrative
Agent-Related Person has made any representation or warranty to it, and that no
act by the Administrative Agent hereafter taken, including any consent to and
acceptance of any assignment or review of the affairs of Borrower, Guarantor, or
any Affiliate thereof, shall be deemed to constitute any representation or
warranty by any Administrative Agent-Related Person to any Lender as to any
matter, including whether Administrative Agent-Related Persons have disclosed
material information in their possession. Each Lender represents to the
Administrative Agent that it has, independently and without reliance upon any
Administrative Agent-Related Person and based on such documents and information
as it has deemed appropriate, made its own appraisal of and investigation into
the business, prospects, operations, property, financial and other condition and
creditworthiness of the Borrower, Guarantor and their respective Subsidiaries,
and all applicable bank or other regulatory Laws relating to the transactions
contemplated hereby, and made its own decision to

                                       73

<PAGE>

enter into this Agreement and to extend credit to the Borrower under the
Agreement. Each Lender also represents that it will, independently and without
reliance upon any Administrative Agent-Related Person and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and decisions in taking or not taking
action under this Agreement and the other Loan Documents, and to make such
investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Borrower and Guarantor. Except for notices, reports and
other documents expressly required to be furnished to the Lenders by the
Administrative Agent herein, the Administrative Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, prospects, operations, property, financial and other
condition or creditworthiness of any of Borrower, Guarantor or any of their
respective Affiliates which may come into the possession of any Administrative
Agent-Related Person.

         Section 12.7 Indemnification of Administrative Agent. Whether or not
the transactions contemplated hereby are consummated, the Lenders shall
indemnify upon demand each Administrative Agent-Related Person (to the extent
not reimbursed by or on behalf of Borrower and without limiting the obligation
of Borrower to do so), pro rata, and hold harmless each Administrative
Agent-Related Person from and against any and all Liabilities and Costs incurred
by it; provided that no Lender shall be liable for the payment to any
Administrative Agent-Related Person of any portion of such Liabilities and Costs
to the extent determined in a final, nonappealable judgment by a court of
competent jurisdiction to have resulted from such Administrative Agent-Related
Person's own gross negligence or willful misconduct; provided further that no
action taken in accordance with the directions of the Required Lenders shall be
deemed to constitute gross negligence or willful misconduct for purposes of this
Section 12.7. Without limitation of the foregoing, each Lender shall reimburse
the Administrative Agent upon demand for its ratable share of any costs or
out-of-pocket expenses (including attorneys' fees and expenses) incurred by the
Administrative Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under, this Agreement, any other Loan Document, or
any document contemplated by or referred to herein, to the extent that the
Administrative Agent is not reimbursed for such expenses by or on behalf of the
Borrower. The undertaking in this Section 12.7 shall survive termination of the
Maximum Commitments, the payment of all other Obligations and the resignation of
the Administrative Agent.

         Section 12.8 Administrative Agent in its Individual Capacity. MAC and
its Affiliates may make loans to, acquire equity interests in and generally
engage in any kind of financial advisory, underwriting or other business with
each of the Borrower or Guarantor and their respective Affiliates as though MAC
were not the Administrative Agent hereunder and without notice to or consent of
the Lenders. The Lenders acknowledge that, pursuant to such activities, MAC or
its Affiliates may receive information regarding Borrower, or its Affiliates
(including information that may be subject to confidentiality obligations in
favor of Borrower or such Affiliate) and acknowledge that the Administrative
Agent shall be under no obligation to provide

                                       74

<PAGE>

such information to them. With respect to its Advances, MAC shall have the same
rights and powers under this Agreement as any other Lender and may exercise such
rights and powers as though it were not the Administrative Agent, and the terms
"Lender" and "Lenders" include MAC in its individual capacity.

         Section 12.9 Successor Administrative Agent. Subject to the appointment
and acceptance of a successor Administrative Agent as provided in this Section
12.9, the Administrative Agent may resign as Administrative Agent upon thirty
(30) days notice to the Lenders and the Administrative Agent may be removed at
any time with or without cause by the Required Lenders. If the Administrative
Agent resigns or is removed under this Agreement, the Required Lenders shall
appoint from among the Lenders a successor Administrative Agent for the Lenders,
which successor Administrative Agent shall be consented to by the Borrower at
all times other than during the existence of an Event of Default (which consent
of the Borrower shall not be unreasonably withheld or delayed). If no successor
Administrative Agent is appointed prior to the effective date of the resignation
or retirement of the Administrative Agent, the Administrative Agent may appoint,
after consulting with the Lenders and the Borrower, a successor Administrative
Agent from among the Lenders. Upon the acceptance of its appointment as
successor Administrative Agent hereunder, the Person acting as such successor
Administrative Agent shall succeed to all the rights, powers and duties of the
retiring or removed Administrative Agent and the term "Administrative Agent"
shall mean such successor Administrative Agent and the retiring or removed
Administrative Agent's appointment, powers and duties as Administrative Agent
shall be terminated. After any retiring Administrative Agent's resignation or
removal hereunder as Administrative Agent, the provisions of this Article XII
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Administrative Agent under this Agreement. If no successor
Administrative Agent has accepted appointment as Administrative Agent by the
date which is thirty (30) days following a retiring Administrative Agent's
notice of resignation, the retiring or removed Administrative Agent's
resignation or removal shall nevertheless thereupon become effective and the
Lenders shall perform all of the duties of the Administrative Agent hereunder
until such time, if any, as the Required Lenders appoint a successor
Administrative Agent as provided for above.

         Section 12.10 Administrative Agent May File Proofs of Claim. In case of
the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to Borrower or Guarantor, the Administrative Agent
(irrespective of whether the principal of Term Loan shall then be due and
payable as herein expressed or by declaration or otherwise and irrespective of
whether the Administrative Agent shall have made any demand on Borrower) shall
be entitled and empowered, by intervention in such proceeding or otherwise:

                  (a)      to file and prove a claim for the whole amount of the
principal and interest owing and unpaid in respect of the Term Loan, and all
other Obligations that are owing and unpaid and to file such other documents as
may be necessary or advisable in order to have the claims of the Lenders and the
Administrative Agent (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Lenders and the Administrative Agent
and their respective Administrative Agents and counsel and all other amounts due
the

                                       75

<PAGE>

Lenders and the Administrative Agent under Sections 2.11 and 13.10 allowed in
such judicial proceeding; and

                  (b)      to collect and receive any monies or other property
payable or deliverable in respect of any such claims and to distribute the same;
and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Lender to make such payments to the Administrative Agent and, in the event
that the Administrative Agent shall consent to the making of such payments
directly to the Lenders, to pay to the Administrative Agent any amount due for
the reasonable compensation, expenses, disbursements and advances of the
Administrative Agent and its Administrative Agents and counsel, and any other
amounts due the Administrative Agent under Sections 2.11 and 13.10.

         Nothing contained herein shall be deemed to authorize the
Administrative Agent to authorize or consent to or accept or adopt on behalf of
any Lender any plan of reorganization, arrangement, adjustment or composition
affecting the Obligations or the rights of any Lender or to authorize the
Administrative Agent to vote in respect of the claim of any Lender in any such
proceeding.

         Section 12.11 Collateral and Guaranty Agreements Matters.

                  (a)      Collateral Matters.

                           (i)      Each Lender authorizes and directs
Administrative Agent to enter into the Security Documents for the ratable
benefit of Lenders. Each Lender agrees that (A) any action taken by
Administrative Agent in respect of any Collateral in accordance with the
provisions of this Agreement or the Security Documents (and with the consent of,
or at the request of, Required Lenders), and (B) the exercise by Administrative
Agent (with the consent of, or at the request of, Required Lenders) of powers in
respect of the Collateral set out in any Security Documents, together with other
reasonably incidental powers, shall be authorized by and binding upon all
Lenders.

                           (ii)     In the event any lien under any Security
Document is, on its face, granted to a Lender rather than to Administrative
Agent (for the ratable benefit of all Lenders), the Administrative Agent,
Lenders, and Borrower confirm that it is their intent that all such liens shall
be granted (or deemed granted) to Administrative Agent for the ratable benefit
of all Lenders. All such Security Documents are hereby amended to the extent
necessary to reflect that the liens granted under those Security Documents are
granted to Administrative Agent (for the ratable benefit of all Lenders), and
Borrower hereby grants all liens under all Security Documents to Administrative
Agent, for the ratable benefit of Lenders.

                           (iii)    Administrative Agent is authorized on behalf
of all Lenders, without the necessity of any notice to or further consent from
any Lender, from time to time while no Default or Event of Default exists, to
take any action with respect to any Collateral or

                                       76

<PAGE>

Security Documents that may be necessary to perfect and maintain the perfection
of the liens upon the Collateral granted by the Security Documents.

                           (iv)     Administrative Agent has no obligation
whatsoever to any Lender or to any other Person to assure that the Collateral
exists or is owned by the party pledging the Collateral or is cared for,
protected or insured or has been encumbered or that the liens granted to
Administrative Agent for the benefit of Lenders under the Security Documents
have been properly or sufficiently or lawfully created, perfected, protected or
enforced, or are entitled to any particular priority.

                           (v)      Administrative Agent shall exercise the same
care and prudent judgment with respect to the Collateral and the Security
Documents as it normally and customarily exercises in respect of similar
collateral and security documents.

                  (b)      Release Collateral. Lenders irrevocably authorize the
Administrative Agent, at its option and in its discretion, to release any lien
or encumbrance on any property granted to or held by the Administrative Agent
under any Loan Document or Security Document (i) upon termination of the Maximum
Commitments and payment in full of all Obligations (other than contingent
indemnification obligations), (ii) that is sold or to be sold as part of or in
connection with any sale permitted under the Agreement or under any other Loan
Document, or (iii) if approved, authorized or ratified in writing by the
Required Lenders.

                  (c)      Subordinate Liens. Lenders irrevocably authorize the
Administrative Agent, at its option and in its discretion, to subordinate any
lien or encumbrance on any property granted to or held by the Administrative
Agent under any Loan Document or Security Document to the holder of any lien or
encumbrance on such property that constitutes a purchase money lien or a capital
lease.

                  (d)      Confirm Authority. Upon request by the Administrative
Agent at any time, the Required Lenders will confirm in writing the
Administrative Agent's authority to release or subordinate its interest in
particular types or items of property.

         Section 12.12 Advance Procedure.

                  (a)      Subject to compliance with Section 2.3 and Article
IX, Borrower may request the Advance of the Term Loan by submitting an Advance
Request to Administrative Agent, and Administrative Agent shall promptly notify
each Lender of the Advance Request and its contents. An Advance Request is
irrevocable and binding on Borrower. Each Advance Request must be received by
Administrative Agent no later than 12:00 p.m. Houston, Texas, Time on the third
Business Day preceding the proposed Advance date.

                  (b)      By 11:00 a.m. Eastern Time on the Advance date, each
Lender shall remit its Commitment Percentage of each requested Advance by wire
transfer to Administrative Agent pursuant to Administrative Agent's wire
transfer instructions on Annex I (or as otherwise directed by Administrative
Agent) in funds that are available for immediate use by

                                       77

<PAGE>

Administrative Agent. Subject to receipt of such funds, Administrative Agent
shall make such funds available to Borrower as directed in the Advance Request
(unless it has actual knowledge that any applicable condition precedent has not
been satisfied by Borrower).

                  (c)      Absent contrary written notice from a Lender,
Administrative Agent may assume that each Lender has made its Commitment
Percentage of the requested Advance available to Administrative Agent on the
applicable Advance date, and Administrative Agent may, in reliance upon such
assumption (but is not required to), make available to Borrower a corresponding
amount. If a Lender fails to make its Percentage Share of any requested Advance
available to Administrative Agent on the applicable Advance date, Administrative
Agent may (to the extent such amount was actually advanced to Borrower) recover
the applicable amount on demand from that Lender, together with interest at the
Federal Funds Rate for the period commencing on the date the amount was made
available to Borrower by Administrative Agent and ending on (but excluding) the
date Administrative Agent recovers the amount from that Lender.

         Section 12.13 Payments. Borrower shall make each payment on the
Obligation as provided in the Agreement, provided that all such payments shall
be paid to Administrative Agent and shall be without offset, counterclaim or
deduction. Any payment of the Obligation from Borrower, Guarantor, or any of
their respective Affiliates which is received by any Lender (including under
Section 11.4), shall be promptly forwarded to Administrative Agent. Payments
received after the designated time will be deemed received on the next Business
Day. Administrative Agent shall pay each Lender any payment to which that Lender
is entitled on the same day Administrative Agent receives the funds from
Borrower if Administrative Agent receives payment before 12 noon Eastern Time.
If Administrative Agent receives the funds at 12 noon or later, Eastern Time,
Administrative Agent shall pay such amount to Lender on the following Business
Day. If and to the extent that Administrative Agent does not make a payment to
Lenders when due, the unpaid amounts shall accrue interest at the Federal Funds
Rate from the due date until (but not including) the date paid.

         Section 12.14 Application of Payments.

                  (a)      If no Default or Event of Default then exists, all
scheduled payments shall be applied in accordance with Section 2.5(e) of this
Agreement.

                  (b)      If no Default or Event of Default then exists, all
prepayments shall be applied first to unpaid fees, expenses, and Related Costs,
second to accrued and unpaid interest on the Term Loan with the balance being
allocated among the Term Notes in accordance with each Lender's Pro Rata Share,
and then applied to the outstanding principal balance of each Term Note. If the
amount of a prepayment is not sufficient to pay in full any component of the
Term Loan, then the amount of such payment shall be applied to the scheduled
principal payments of such loan in the inverse order of their maturity.

                  (c)      All proceeds realized from the liquidation or other
disposition of Collateral or otherwise received after maturity of the Notes,
whether by acceleration or

                                       78

<PAGE>

otherwise, shall be applied: first, to reimbursement of expenses and indemnities
provided for in this Agreement and the Security Documents; second, to accrued
interest on the Notes; third, to fees; fourth, pro rata to principal outstanding
on the Notes and Obligations in respect of the Swap Agreement; fifth, to any
other Obligations; and any excess shall be paid to the Borrower or as otherwise
required by any Governmental Requirement.

         Section 12.15 Liens. The liens granted by Borrower under the Loan
Documents are granted to the Administrative Agent for the ratable benefit of the
Lenders. It is the intent of the Lenders that they share an equal priority lien
in all of the Collateral, regardless of any previous recordations or filings,
the name of the grantee or secured party in the applicable Security Document,
and regardless of the timing of any additional recordations or filings, and that
the enforcement of all of their respective rights and remedies under the Loan
Documents is subject to the terms and provisions of this Agreement. SUBJECT TO
THE TERMS OF THE INTERCREDITOR AGREEMENT, ALL LIENS OF ANY LENDER IN ANY OF THE
COLLATERAL SHALL BE PARI PASSU WITH ALL LIENS OF THE OTHER LENDERS IN SUCH
COLLATERAL AND ALL SUCH LIENS SHALL HAVE EQUAL PRIORITY.

         Section 12.16 Payment Priority. The right of each Lender to receive any
payments or prepayments under or in respect of the Agreement, any Loan Document,
or any Collateral shall be pari passu with the payment rights of all other
Lenders acting in their capacity as a Lender pursuant to this Agreement,
provided that payments of principal and interest will be allocated to each
Lender in accordance with its Pro Rata Share of such payment or prepayment.

         Section 12.17 Sharing of Payments by Lenders. If any Lender shall, by
exercising any right of set-off or counterclaim or otherwise, obtain payment in
respect of any principal of or interest on any of its Advances or fees resulting
in such Lender receiving payment of a greater proportion of the aggregate amount
of its Advances or fees and accrued interest thereon than the proportion
received by any other Lender, then the Lender receiving such greater proportion
shall purchase (for cash at face value) participations in the Advances or fees
of other Lenders to the extent necessary so that the benefit of all such
payments shall be shared by the Lenders ratably in accordance with the aggregate
amount of principal of and accrued interest on their respective Advances;
provided that (a) if any such participations are purchased and all or any
portion of the payment giving rise thereto is recovered, such participations
shall be rescinded and the purchase price restored to the extent of such
recovery, without interest, and (b) the provisions of this Section 12.17 shall
not be construed to apply to any payment made by the Borrower pursuant to and in
accordance with the express terms of this Agreement or any payment obtained by a
Lender as consideration for the assignment of or sale of a participation in any
of its Advances to any assignee or participant, other than to the Borrower or
any Affiliate thereof (as to which the provisions of this Section 12.17 shall
apply). The Borrower consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against the
Borrower rights of set-off and counterclaim with respect to such participation
as fully as if such Lender were a direct creditor of the Borrower in the amount
of such participation.

         Section 12.18 Relationship of Lenders. This Agreement, and the
documents delivered in connection herewith, does not create a partnership or
joint venture among Administrative Agent and Lenders or among the Lenders.

                                  ARTICLE XIII.
                                  Miscellaneous

         Section 13.1 Remedies Cumulative. Lenders' rights and remedies under
this Agreement are cumulative and non-exclusive of any other rights or remedies
it may have under any other agreement or instrument, or by operation of law or
otherwise.

         Section 13.2 Assignment. This Agreement is entered into for the benefit
of Borrower and Lenders and their respective successors and assigns. It will be
binding upon and inure to the benefit of those parties and their respective
successors and assigns. The rights and obligations of Borrower under this
Agreement, the Term Note, the other Security Documents, the Swap Agreement or
any other Loan Document to which Borrower is a party may not be assigned without
Lenders' prior written consent. Lenders may assign, transfer or otherwise
dispose of any of its rights or obligations under this Agreement or any of the
other Loan Documents with the consent of Borrower, which consent will not be
unreasonably withheld. Lenders may assign interests or participation in this
Agreement and the other Loan Documents with the prior written consent of
Borrower, which consent shall not be unreasonably withheld; provided, that if
any Event of Default has occurred and is continuing or any circumstance exists
which could, with notice to Borrower or the lapse of time or both result in an
Event of Default, Borrower's consent to such an assignment by Lenders shall not
be required. To the extent Lenders assigns to any other Person an interest in
the Term Note pursuant to one or more Lender Participation Transactions,
Borrower shall execute and deliver to Lenders any Lender Participation Documents
reasonably necessary in connection with such transaction, including the issuance
by Borrower of one or more Term Notes. Additionally, Lenders will be entitled to
grant and assign a security interest in its right, title and interest in and to
the Term Note, the Security Documents and all other Loan Documents to its
Lenders or Lenders as security for indebtedness of the Lenders.

         Section 13.3 Notices. Any notice, demand or document which any party is
required or may desire to give to any other will be in writing and, except as
otherwise provided in this Agreement, given by messenger, overnight delivery,

         If to any other obligor party, the notice will be sent to the address
set forth in the Security Document or other Loan Document to which the recipient
is a party.

         Any notice delivered or made by messenger, telecopy, electronic mail or
United States mail will be deemed to be given on the date of actual delivery as
shown by messenger receipt, the sender's facsimile machine confirmation or other
verifiable electronic receipt, or the registry or certification receipt.
Notwithstanding the previous sentence, if either party receives from the other
any message via electronic mail that purports to be a notice under this
Agreement but that contains information that is syntactically incorrect, garbled
or otherwise unintelligible, the recipient will promptly notify the sender and
the message containing the unintelligible information will not be deemed to be
given until it is successfully delivered (including redelivery by electronic
mail) pursuant to this Section 13.3. If Lenders receives oral notice of any
event from an authorized officer of Borrower, Lenders will not be required to
delay the exercise of any rights arising from the occurrence of that event until
it receives written confirmation of the oral notice. In the event that a
discrepancy exists between the notice received by Lenders orally and the written
confirmation, or in the absence of a written confirmation, the oral notice, as
understood by Lenders will be deemed the controlling and proper notice.

         Section 13.4 Waivers; Amendments.

                  (a)      No failure on the part of the 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, or any abandonment or discontinuance
of steps to enforce such right, power or privilege, under any of the Loan
Documents shall operate as a waiver thereof, nor shall any single or partial
exercise 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 rights and remedies of the Administrative Agent
and the Lenders hereunder and under the other Loan Documents are cumulative and
are not exclusive of any rights or remedies that they would otherwise have. No
waiver of any provision of this Agreement or any other Loan Document or consent
to any departure by the Borrower therefrom shall in any event be effective
unless the same shall be permitted by Section 13.4(b), and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given. Without limiting the generality of the foregoing, the making of an
Advance shall not be construed as a waiver of any Default, regardless of whether
the Administrative Agent or any Lender may have had notice or knowledge of such
Default at the time.

                  (b)      Neither this Agreement nor any provision hereof or of
any other Loan Document may be waived, amended or modified except pursuant to an
agreement or agreements in writing entered into by the Borrower and the Required
Lenders or by the Borrower and the Administrative Agent with the consent of the
Required Lenders; provided that no such agreement shall (i) increase the
Commitment of any Lender without the written consent of such Lender, (ii) reduce
the principal amount of any Advance or reduce the rate of interest thereon, or
reduce any fees payable hereunder, or reduce any other Obligations hereunder or
under any other Loan Document, without the written consent of each Lender
affected thereby, (iii) postpone the scheduled date of payment of the principal
amount of any Advance, or any interest thereon, or

                                       82

<PAGE>

any fees payable hereunder, or any other Obligations hereunder or under any
other Loan Document, or reduce the amount of, waive or excuse any such payment,
or postpone or extend the Termination Date without the written consent of each
Lender affected thereby, (iv) change the Agreement in a manner that would alter
the pro rata sharing of payments required thereby, without the written consent
of each Lender, (v) change the definition of the term "Subsidiary," without the
written consent of each Lender, (vi) release any Guarantor (except as set forth
in the Guaranty Agreements), release any of the collateral (except as expressly
provided in Section 12.11(b), or change Section 6.26, without the written
consent of each Lender, or (vii) change any of the provisions of this Section
13.4(b) or the definitions of "Required Lenders" or any other provision hereof
specifying the number or percentage of Lenders required to waive, amend or
modify any rights hereunder or under any other Loan Documents or make any
determination or grant any consent hereunder or any other Loan Documents,
without the written consent of each Lender; provided further that no such
agreement shall amend, modify or otherwise affect the rights or duties of the
Administrative Agent hereunder or under any other Loan Document without the
prior written consent of the Administrative Agent.

         Section 13.5 Confidentiality. Except as may be required (a) by
applicable rules of NASDAQ or the United States Securities and Exchange
Commission, (b) by applicable law, (c) in response to or in connection with
arbitration proceedings or legal process or in any legal proceeding to enforce
or interpret the Security Documents or any other document or instrument executed
in connection with the Security Documents, and (d) in any filings necessary or
appropriate to create, maintain and perfect liens and security interests
contemplated by this Agreement, neither party will release this Agreement or any
other document, agreement or instrument relating to or executed in conjunction
with this Agreement, or disclose the substantive terms of any of them except to
its attorneys, accountants or engineers on a need-to-know basis, without the
prior written consent of the other party. Notwithstanding the previous sentence,
Lenders may disclose the substantive terms of or furnish its Lenders and
potential Lenders and investment bankers and their respective attorneys,
accountants or engineers with copies of this Agreement or any Security Document
or any other document agreement or instrument relating to or executed or
delivered to Lenders in conjunction with this Agreement without the consent of
Borrower. Except as required by applicable rules of NASDAQ or the United States
Securities Exchange Commission, neither party or any of their respective
Affiliates will issue any press release or make any other public announcement
relating to this Agreement without the prior written consent of the other party;
provided, however, Lenders and Borrower may each publish a "tombstone"
announcement regarding this Agreement. Notwithstanding anything herein to the
contrary, the information protected by this Section 13.5 will not include, and
Lenders may disclose to any and all Persons, without limitation of any kind, any
information with respect to the "tax treatment" and "tax structure" (in each
case, within the meaning of Treasury Regulation Section 1.6011-4) of the
transactions contemplated hereby and all materials of any kind (including
opinions or other tax analyses) that are provided to Lenders relating to such
tax treatment and tax structure; that, with respect to any document or similar
item that in either case contains information concerning the tax treatment or
tax structure of the transaction as well as other information, this sentence
shall only apply to such portions of the document or similar item that relate.

         Section 13.6 Final Agreement. This Agreement and the other agreements
to which this Agreement refers, together with all exhibits, schedules and
annexes attached to any of them, constitute the final, entire agreement among
the parties and supersede any prior oral or written and all contemporaneous oral
proposals, commitments, promises, agreements and understandings between the
parties with respect to the subject matter of this Agreement and the other Loan
Documents, all of which are merged into and replaced by the Loan Documents.

         Section 13.7 WAIVER OF JURY TRIAL, PUNITIVE DAMAGES, ETC. EACH OF
BORROWER AND LENDERS KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY (A)
WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON THIS AGREEMENT, OR DIRECTLY
OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THE LOAN
DOCUMENTS OR ANY TRANSACTION CONTEMPLATED OR ASSOCIATED WITH ANY OF THEM, BEFORE
OR AFTER MATURITY; (B) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY
RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY "SPECIAL
DAMAGES", AS DEFINED BELOW; (C) CERTIFIES THAT NEITHER IT NOR ANY OF ITS

         Section 13.13 Captions; Headings. The headings, captions and
arrangements contained in this Agreement have been inserted for convenience only
and will not be deemed in any manner to modify, explain, enlarge or restrict any
provision in this Agreement.

         Section 13.14 Construction. Borrower and Lenders acknowledge that each
of them has had the benefit of legal counsel of its own choice and has been
afforded an opportunity to review this Agreement, the Term Note and each of the
other Loan Documents with its legal counsel and that this Agreement and the
other Security Documents will be construed as if jointly drafted by Borrower and
Lenders.

         Section 13.15 Additional Documents. From time to time after the date of
this Agreement, each of the parties hereto agrees to execute and deliver or
cause to be executed and delivered, all reasonable documents and instruments,
and take any other reasonable and lawful action as the other party may deem
necessary or desirable to perfect or evidence perfection of its security
interest, to enforce its rights under this Agreement or to otherwise effectuate
the purposes of this Agreement. Upon the full payment and complete discharge of
Borrower's Obligations under this Agreement and the other Loan Documents,
Lenders will, at the request and expense of Borrower, prepare and deliver
documents evidencing the release and termination of the liens, security
interests, and other interests of Lenders under the Security Documents.

         Section 13.16 Counterpart Execution. This Agreement may be executed
simultaneously in one or more counterparts, each of which will be deemed an
original, but all of which together will constitute one and the same instrument.

         Section 13.17 Compliance with Law. It is the intention of the parties
to comply with applicable usury laws (now or later enacted). Accordingly, and
notwithstanding any provision to the contrary in this Agreement, the other
Security Documents or any other Loan Document, in no event will this Agreement
or any other Loan Document require the payment or permit the collection of
interest in excess of the maximum amount permitted by those laws. If, under any
circumstances, the fulfillment of any provision of this Agreement or of any
other Loan Document will involve exceeding the limit prescribed by applicable
law for the contracting for or charging or collecting interest, then, ipso
facto, the obligation to be fulfilled will be reduced to the allowable limit,
and if, under any circumstances, Lenders ever receives pursuant to any of the
Loan Documents anything of value as interest or that is deemed to be interest
under applicable law that would exceed the highest lawful rate, the amount that
would otherwise be excessive interest will be applied to the reduction of the
principal amount owing under the Term Note or on account of any other
indebtedness owed by Borrower to Lenders, and not to the payment of interest;
or, if any portion of the excessive interest exceeds the unpaid balance of
principal of that indebtedness, then the excess amount will be refunded to
Borrower. In determining whether or not the interest paid or payable with
respect to any indebtedness owed by Borrower to Lenders exceeds the highest
lawful rate, Borrower and Lenders will, to the maximum extent permitted by
applicable law, (a) characterize any non-principal payment as an expense, fee or
premium rather than as interest, (b) exclude voluntary prepayments and the
effects of them, (c) amortize, prorate, allocate and spread the total amount of
interest throughout the full term of the indebtedness so that the actual rate of
interest on account of the indebtedness does not exceed the maximum

                                       87

<PAGE>

amount permitted by applicable law, and (d) allocate interest between portions
of the indebtedness so that no portion will bear interest at a rate greater than
that permitted by applicable law.

         Section 13.18 EXCULPATION PROVISIONS. EACH OF THE PARTIES AGREES THAT
IT HAS A DUTY TO READ THIS AGREEMENT AND EACH OF 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 EACH OF THE OTHER LOAN DOCUMENTS AND IS FULLY INFORMED AND HAS FULL NOTICE

CERTAIN 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 THAT LIABILITY. EACH PARTY AGREES AND
COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY
EXCULPATORY PROVISION OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS ON
THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF THE PROVISION OR THAT THE
PROVISION IS NOT "CONSPICUOUS."

         Section 13.19 No Other Agreements; No Parol Evidence. THIS AGREEMENT
AND THE OTHER LOAN DOCUMENTS CONSTITUTE A "WRITTEN LOAN AGREEMENT" BETWEEN THE
PARTIES WITH RESPECT TO THE MATTERS ADDRESSED IN THEM AND WILL NOT BE
CONTRADICTED BY EVIDENCE OF ANY PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES AND, EXCEPT

THERE ARE NO PRIOR OR CONTEMPORANEOUS WRITTEN AGREEMENTS BETWEEN THE PARTIES
THAT WILL SURVIVE THE EXECUTION OF THIS AGREEMENT.
