  EDGE PETROLEUM CORPORATION
  NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------
  1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


          The financial statements included herein have been prepared by Edge
     Petroleum Corporation, a Delaware corporation (the "Company"), without
     audit pursuant to the rules and regulations of the Securities and Exchange
     Commission, and reflect all adjustments which are, in the opinion of
     management, necessary to present a fair statement of the results for the
     interim periods on a basis consistent with the annual audited consolidated
     financial statements.  All such adjustments are of a normal recurring
     nature.  The results of operations for the interim period are not
     necessarily indicative of the results to be expected for an entire year. 
     Certain information, accounting policies and footnote disclosures normally
     included in financial statements prepared in accordance with generally
     accepted accounting principles have been omitted pursuant to such rules and
     regulations, although the Company believes that the disclosures are
     adequate to make the information presented not misleading.  Certain prior
     year amounts have been reclassified to conform to the current year
     presentation.  Such reclassifications do not affect net income.  These
     financial statements should be read in conjunction with the Company's
     audited consolidated financial statements included in the Company's Annual
     Report on Form 10-K for the year ended December 31, 1997. 

     Comprehensive Income - The Financial Accounting Standards Board issued
     Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
     Comprehensive Income".  This statement establishes standards for reporting
     and display of comprehensive income and its components in the Company's
     financial statements.  Comprehensive income includes all changes in the
     Company's equity except investments by and distributions to owners and
     includes, among other things, foreign currency translation adjustments. 
     This standard is effective for financial statements for periods beginning
     after December 15, 1997.  The adoption of SFAS No. 130 had no material 
     effect on the Company's financial condition or results of operations as 
     the Company currently has no items of other comprehensive income.

  2. NOTES PAYABLE AND LONG TERM DEBT

          During July 1995, the Company entered into a revolving credit facility
     (the "Revolving Credit Facility") with a bank to finance temporary working
     capital requirements.  The Revolving Credit Facility provided up to
     $20,000,000 in borrowings limited by a borrowing base (as defined by the
     Revolving Credit Facility).  The Revolving Credit Facility provided for
     interest at the lender's prime rate plus 0.75%.  The borrowing base was
     subject to review by the bank on a quarterly basis and could be adjusted
     subject to the provisions of the Revolving Credit Facility.  On March 3,
     1997 the Company repaid the outstanding balance of $11,017,348 plus accrued
     interest with proceeds from the initial public offering.  Effective April
     1, 1998, the Company amended and restated its Revolving Credit Facility to
     provide a revolving line of credit of up to $100 million bearing interest
     at a floating rate equal to LIBOR plus 1.5% - 2% depending on the level of
     borrowing base utilization.  The Company's initial borrowing base 
     authorized by the banks is approximately $15 million.  Beginning 
     September 1, 1998, the borrowing base will be redetermined semi-annually 
     by unanimous consent of the banks and from time to time at the Company's 
     or the bank's request.  Beginning May 1, 1998 and on the first day of each
     month thereafter, the borrowing base is required to be reduced by $525,000.

     The Revolving Credit Facility provides for certain restrictions, 
     including but not limited to, limitations on additional borrowings and 
     issues of capital stock, sales of its oil and natural gas properties or 
     other collateral, engaging in merger or consolidation transactions and 
     prohibitions of dividends and certain distributions of cash or properties 
     and certain liens.  The Revolving Credit Facility also contains the 
     following financial covenants: (i) tangible net worth (total assets 
     exclusive of certain intangibles minus liabilities) must be at least $43 
     million plus 50% of positive net income and 100% of equity raised for all 
     quarterly periods subsequent to December 31, 1997; (ii) the ratio at the 
     end of any quarter of cash flow (net income plus proceeds of certain 
     project sales, depletion, depreciation, amortization and other non-cash 
     expenses less non-cash net income for such quarter) must be at least 1.25 
     to 1.00; and (iii) the ratio at the end of any quarter of EBIT (net 
     income plus interest expense and taxes, excluding non-cash, extraordinary 
     expenses and income) to interest expense for the proceeding 12-month 
     period must be at least 4.5 to 1.00.  The Revolving Credit Facility is 
     secured by substantially all the assets of the Company.

  3. EARNINGS PER SHARE

           During 1997, the Company implemented SFAS No. 128 - "Earnings
     per Share," which establishes the requirements for presenting earnings
     per share ("EPS").  SFAS No. 128 requires the presentation of "basic"
     and "diluted" EPS on the face of the income statement.  Basic earnings
     per common share amounts are 

                                    6
<PAGE>

     calculated using the average number of common shares outstanding during
     each period.  Diluted earnings per share assumes the exercise of all 
     stock options having exercise prices less than the average market price
     of the common stock using the treasury stock method.  The earnings per 
     share data for prior years has been restated following the standards in
     SFAS No. 128.

          The following is presented as a reconciliation of the numerators
     and denominators of basic and diluted earnings per share computations,
     in accordance with SFAS No. 128.

</TABLE>

          The Company was organized through an initial public offering and
     a series of combination transactions (the "Combination") which were
     accounted for as a reorganization of entities under common control. 
     Accordingly, for the three months ended March 31, 1997, the number of
     shares outstanding has been computed assuming that 4,701,361 shares of
     common stock originally issued in connection with the Combination,
     effective February 25, 1997, were outstanding from the beginning of
     the period.

ITEM 2.         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                     CONDITION AND RESULTS OF OPERATIONS

     The following is management's discussion and analysis of certain
significant factors that have affected certain aspects of the Company's
financial position and operating results during the periods included in the
accompanying unaudited condensed consolidated financial statements.  This
discussion should be read in conjunction with the accompanying unaudited
condensed consolidated financial statements included elsewhere in this Form 10-Q
and with the Company's audited consolidated financial statements included in the
Company's annual report on Form 10-K for the year ended December 31, 1997. 
Unless otherwise indicated by the context, references herein to the "Company"
mean Edge Petroleum Corporation, a Delaware corporation that is the registrant,
and its corporate and partnership subsidiaries and predecessors.

OVERVIEW

     Edge Petroleum Corporation is an independent energy company engaged in the
exploration, development and production of oil and natural gas.  Edge conducts
its operations primarily along the onshore Gulf Coast with its primary emphasis
in South Texas and Louisiana where it currently controls interests in excess of
236,000 gross acres under lease and option.  The Company explores for oil and
natural gas by emphasizing an integrated application of highly advanced data
visualization techniques and computerized 3-D seismic data analysis to identify
potential hydrocarbon accumulations.  The Company believes its approach to
processing and analyzing geophysical data differentiates it from other
independent exploration and production companies and is more effective than
conventional 3-D seismic data interpretation methods.  The Company also believes
that it maintains one of the largest databases of onshore South Texas Gulf Coast
3-D seismic data of any independent oil and natural gas company, and is
continuously acquiring substantial additional data within this core region.

                                     7
<PAGE>

     The Company acquires 3-D seismic data by organizing and designing regional
data acquisition surveys for its proprietary use, as well as through selective
participation in regional non-proprietary 3-D surveys.  The Company negotiates
seismic options for a majority of the areas encompassed by its proprietary
surveys, thereby allowing it to secure identified prospect leasehold interests
on a non-competitive, pre-arranged basis.  In the Company's non-proprietary 3-D
survey areas, the Company's technical capabilities allow it to rapidly and
comprehensively evaluate large volumes of regional 3-D seismic data,
facilitating its ability to identify attractive prospects within a surveyed
region and to secure the corresponding leasehold interests ahead of other
industry participants.
     
     The Company's extensive technical expertise has enabled it to internally 
generate substantially all of its 3-D prospects drilled to date and to 
assemble a large portfolio of 3-D based drilling prospects.  The Company 
pursues drilling opportunities that include a blend of shallower, normally 
pressured reservoirs that generally involve moderate costs and risks as well 
as deeper, over-pressured reservoirs that generally involve greater costs and 
risks, but have higher economic potential.  During the past year, the Company 
has expanded its relative focus to increase its exposure to exploration 
opportunities with deeper targets.  The Company mitigates its exposure to 
exploration costs and risk by conducting its operations with industry 
partners, including major oil companies and large independents, that 
generally pay a disproportionately greater share of seismic acquisition and, 
in many instances, leasing and drilling costs than the Company.

     The Company uses the full-cost method of accounting for its oil and natural
gas properties.  Under this method, all acquisition, exploration and development
costs that are directly attributable to the Company's acquisition, exploration
and development activities are capitalized in a "full-cost pool" as incurred. 
The Company records depletion of its full-cost pool using the unit of production
method.  To the extent that such capitalized costs in the full cost pool (net of
depletion, depreciation and amortization and related deferred taxes) exceed the
present value (using a 10% discount rate) of estimated future net after-tax cash
flows from proved oil and natural gas reserves, such excess costs are charged to
operations.  Once incurred, a write-down of oil and natural gas properties is
not reversible at a later date.

     Due to the instability of oil and natural gas prices, the Company has
entered into, from time to time, price risk management transactions (e.g., swaps
and collars) for a portion of its natural gas production to achieve a more
predictable cash flow, as well as to reduce exposure from price fluctuations. 
While the use of these arrangements limits the benefit to the Company of
increases in the price of natural gas it also limits the downside risk of
adverse price movements.  The Company's hedging arrangements apply to only a
portion of its production and provide only partial price protection against
declines in natural gas prices and limits potential gains from future increases
in prices.  The Company accounts for these transactions as hedging activities
and, accordingly, gains and losses are included in oil and natural gas revenues
during the period the hedged transactions occur.  During the three months ended
March 31, 1998, the Company had in place two natural gas commodity collars with
a financial institution one of which expired on January 31, 1998 with the other
expiring on April 30, 1998.  These collars cover 5,000 MMbtus per day, or
approximately 29% of the Company's daily production, with floating floor and
ceiling prices ranging between $2.25 and $3.15 per MMbtu, (delivered price
basis, Houston Ship Channel), with settlement for each calendar month occurring
five business days following the publishing of the Inside F.E.R.C. Gas Marketing
Report.  Total natural gas production marketed under these arrangements was
450,000 MMbtu for the three months ended March 31, 1998.  Included within
natural gas revenues for the three months ended March 31, 1998 was $36,700
representing a net gain from current collar activity.  Additionally, during the
three months ended March 31, 1998, the Company has entered into a collar
arrangement with a financial institution that begins and expires on April 1,
1998 and June 30, 1998, respectively.  This collar arrangement covers 10,000
MMbtus per day with a floating floor and ceiling price ranging between $2.15 and
$2.37 per MMbtu.  There was no material hedging activity during the three months
ended March 31, 1997.

     The Company's revenue, profitability and future rate of growth and ability
to borrow funds or obtain additional capital, and the carrying value of its
properties, are substantially dependent upon prevailing prices for oil and
natural gas.  These prices are dependent upon numerous factors beyond the
Company's control, such as economic, political and regulatory developments and
competition from other sources of energy.  The energy markets have historically
been very volatile, and there can be no assurance that oil and natural gas
prices will not be subject to wide fluctuations in the future.  A substantial or
extended decline in oil and natural gas prices could have a material 

                                      8

adverse effect on the Company's financial condition, results of operation and 
access to capital, as well as the quantities of oil and natural gas reserves 
that the Company may economically produce

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THE THREE MONTHS ENDED MARCH 31,
1997

REVENUE AND PRODUCTION

     Oil and natural gas revenues for the three months ended March 31, 1998
increased 10% from $3.4 million to $3.8 million as compared to the three months
ended March 31, 1997.  Production volumes for oil and condensate for the three
months ended March 31, 1998 increased 45% from 29 MBbls to 42 MBbls as compared
to the three months ended March 31, 1997.  The increase in oil and condensate
production during the three months ended March 31, 1998 increased revenues by
$295,929 (based on prior quarter average prices), offset by a 40% decrease in
the average oil sales price which decreased revenues by $376,464 (based on
current quarter production).  Production volumes for natural gas for the three
months ended March 31, 1998 increased 29% from 1,022 MMcfs to 1,323 MMcfs as
compared to the three months ended March 31, 1997.  The increase in natural gas
production during the three months ended March 31, 1998 increased revenues by
$856,424, offset by a 11% decrease in the average natural gas sales price which
decreased revenues by $431,224.  The increase in oil and natural gas production
was primarily due to 79 gross (34.04 net) new exploratory and development wells
being successfully drilled and completed since March 31, 1997 partially offset
by normal production declines from existing wells.  During the three months
ended March 31, 1998 the Company marketed its natural gas produced from a
certain gas field under the terms of various fixed volume natural gas contracts.
Prices received for production marketed under these agreements averaged $2.26
and $2.38 for the three months ended March 31, 1998 and 1997 respectively. 
Total production, (net to the Company's interest) marketed under these
agreements for the three-month periods ended March 31, 1998 and March 31, 1997
was approximately 306,000 Mcf and 334,000 Mcf, respectively, representing
approximately 19% and 28%, respectively, of total production, on a Mcfe basis. 
As described above, included within natural gas revenues for the three months
ended March 31, 1998 was $36,700 representing gains from current collar
activity.  The collar settlements increased the effective natural gas sales
price by approximately $0.03 per Mcf, or 1%, for the three-month period ended
March 31, 1998.  There was no material hedging activity during the three months
ended March 31, 1997.

COSTS AND OPERATING EXPENSES

     Oil and natural gas operating expenses for the three months ended March 31,
1998 increased 7% from $628,413 to $671,184 as compared to the three-month
period ended March 31, 1997.  Oil and natural gas operating expenses were $0.43
per Mcfe and $0.53 Mcfe for the three-month periods ended March 31, 1998 and
1997, 

                                      9
<PAGE>
 
respectively.  The reduction in oil and natural gas operating expenses on
a Mcfe basis is due to the continued emphasis on drilling larger production
volume wells which are more efficient to operate.

     Depletion, depreciation and amortization expense ("DD&A") for the three
months ended March 31, 1998 increased 70% from $615,764 to $1,046,977 as
compared to the three months ended March 31, 1997.  Included within DD&A for the
three-month periods ended March 31, 1998 and 1997 was $883,825 and $478,142,
respectively, representing depletion expense of oil and natural gas property,
which increased by 85%.  Increased oil and natural gas production increased
depletion expense by $151,652 and a 40% increase in the overall depletion rate
further increased depletion expense by $254,031.  The increase in the depletion
rate was primarily due to a 6.3 Bcfe year-end 1997 downward revision to prior
year oil and gas reserve estimates.  The rate was further increased as a result
of increased cost associated with reserve additions since March 31, 1997. 
Depletion on a unit of production basis for the three-month periods ended March
31, 1998 and 1997 was $0.56 per Mcfe and $0.40 per Mcfe, respectively.  The
remaining increase in DD&A is due primarily to depreciation of new computer
hardware, software and office improvements purchased since March 31, 1997.

     General and administrative expenses ("G&A") for the three months ended
March 31, 1998 increased 53% from $920,580 to $1,406,276, as compared to the
three-month period ended March 31, 1997.  The increase in G&A was primarily
attributable to the hiring of additional employees to support the Company's
increased level of exploration activities and 3-D project generation and costs
associated with being a public company.  Included within general and
administrative expenses for the three months ended March 31, 1998 and 1997, is
$199,855 and $235,000, respectively, of overhead reimbursements and management
fees received from various management, operating and seismic agreements. 
General and administrative expenses on a unit of production basis for the three
month periods ended March 31, 1998 and 1997 were $0.89 per Mcfe and $0.77 per
Mcfe, respectively. 

     Unearned compensation expense for the three months ended March 31, 1998
increased from $48,238 to $155,052 as compared to the three-month period ended
March 31, 1997, due to the amortization of restricted stock which was granted
during March 1997 contemporaneously with the Company's initial public offering.

     Interest expense for the three months ended March 31, 1997 was $180,307. 
No Interest expense was recorded during 1998 as a result of the Company repaying
all of its long-term debt during March 1997 with proceeds from the initial
public offering.

      Interest income for the three months ended March 31, 1998 decreased from
$108,226 to $46,045, compared to the three-month period ended March 31, 1997. 
The decrease in interest income is due to the overall reduction in invested
funds.

     Income tax expense for the three months ended March 31, 1998 decreased from
$224,574 to $193,756 as compared to the three-month period ended March 31, 1997.
The decrease in income tax expense during the three-month period ended March 31,
1998 is due to reduced earnings of the Company.  Additionally, the lower
effective tax rate during the three-month period ended March 31, 1997 was due to
the utilization of available tax assets.  The Company's unrecognized net
deferred tax assets have been substantially utilized as of December 31, 1997 and
the Company began providing federal income taxes at the statutory rate, which
approximates the effective rate, during the first quarter of 1998.

     For the three months ended March 31, 1998, the Company had operating income
of $506,177, as compared to operating income of $1,228,006 for the same period
in 1997.

LIQUIDITY AND CAPITAL RESOURCES

     In March 1997, the Company completed its initial public offering (the
"Offering") of 2,760,000 shares of common stock at a public offering price of
$16.50 per share.  The Offering provided the Company with proceeds of
approximately $40 million, net of expenses.  The Company used approximately
$12.7 million to repay its long-term outstanding indebtedness incurred under its
revolving credit facility (the "Revolving Credit Facility"), subordinated loans
and equipment loans.  The remaining proceeds from the Offering, together with
cash flows from operations, 

                                     10
<PAGE>

were used to fund planned capital expenditures, commitments, other working 
capital requirements and for general corporate purposes.

     The Company had cash and cash equivalents at March 31, 1998 of $1.4 
million, consisting primarily of short-term money market investments, as 
compared to $3.8 million at December 31, 1997.  Working capital was $3.2 
million at March 31, 1998, as compared to $7.6 million at December 31, 1997.

     Operating cash flow before changes in working capital was approximately 
$1.8 million for both three-month periods ended March 31, 1998 and 1997. 
Operating cash flow, a measure of performance for exploration and production 
companies, represents cash flows from operating activities prior to charges 
in assets and liabilities.  Operating cash flow should not be considered in 
isolation or as a substitute for net income, operating income, cash flows 
from operating activities or any other measure of financial performance 
presented in accordance with generally accepted accounting principles or as a 
measure of profitability or liquidity.

     During the three months ended March 31, 1998, the Company continued to 
reinvest a substantial portion of its cash flows to increase its 3-D project 
portfolio, improve its 3-D seismic interpretation technology and fund its 
drilling program.  Capital expenditures during the three months ended March 
31, 1998 were $7.9 million as compared to $2.1 million during the same period 
in 1997.  The Company's drilling efforts resulted in the drilling of 22 gross 
(10.29 net) wells in the first quarter of 1998 as compared to 15 gross (4.94 
net) wells during the same period in 1997.  The Company expects capital 
expenditures in 1998 to be at least $30 million.  A substantial portion of 
capital expenditures in 1998 will be invested in the Company's portfolio of 
3-D prospects to fund drilling activities in an effort to expand its reserve 
base. In addition, the Company expects to continue to expand and improve its 
technological and 3-D seismic interpretation capabilities.  The Company may 
seek overseas direct investment opportunities with Frontera Resources 
Corporation and, particularly in Latin America, with others.

       Due to the Company's active exploration and development and technology
enhancement programs, the Company has experienced and expects to continue to
experience substantial working capital requirements.  The Company intends to
fund its 1998 capital expenditures, commitments and working capital requirements
through cash flows from operations, borrowings and to the extent necessary other
financing activities.  The Company believes it will have sufficient capital
resources and liquidity to fund its capital expenditures and meet such financial
obligations as they come due.  In the event such capital resources are not
available to the Company, its drilling and other activities may be curtailed.

REVOLVING CREDIT FACILITY

     During July 1995, the Company entered into a Revolving Credit Facility 
with a bank to finance temporary working capital requirements.  The Revolving 
Credit Facility provided up to $20,000,000 in borrowings limited by a 
borrowing base (as defined by the Revolving Credit Facility).  The Revolving 
Credit Facility provided for interest at the lender's prime rate plus 0.75%.  
The borrowing base was subject to review by the bank on a quarterly basis and 
could be adjusted subject to the provisions of the Revolving Credit Facility. 
On March 3, 1997, the Company repaid the outstanding balance of $11,017,348 
plus accrued interest with proceeds from the initial public offering.  
Effective April 1, 1998, the Company amended and restated its Revolving 
Credit Facility to provide a revolving line of credit of up to $100 million 
bearing interest at a floating rate equal to LIBOR plus 1.5% - 2% depending 
on the level of borrowing base utilization.  The Company's initial borrowing 
base authorized by the banks is approximately $15 million.  Beginning 
September 1, 1998, the borrowing base will be redetermined semi-annually by 
unanimous consent of the banks and from time to time at the Company's or the 
bank's request.  Beginning May 1, 1998 and on the first day of each month 
thereafter, the borrowing base is required to be reduced by $525,000.
 
     The Revolving Credit Facility provides for certain restrictions, 
including but not limited to, limitations on additional borrowings and issues 
of capital stock, sales of its oil and natural gas properties or other 
collateral, engaging in merger or consolidation transactions and prohibitions 
of dividends and certain distributions of cash or properties and certain 
liens.  The Revolving Credit Facility also contains the following financial 
covenants: (i) tangible net worth (total assets exclusive of certain 
intangibles minus liabilities) must be at least $43 million plus 50% of 
positive net income and 100% of equity raised for all quarterly periods 
subsequent to December 31, 1997; (ii) the ratio at the end of any quarter of 
cash flow (net income plus proceeds of certain project sales, depletion, 

                                      11
<PAGE>

depreciation, amortization and other non-cash expenses less non-cash net 
income for such quarter) must be at least 1.25 to 1.00; and (iii) the ratio 
at the end of any quarter of EBIT (net income plus interest expense and 
taxes, excluding non-cash, extraordinary expenses and income) to interest 
expense for the proceeding 12-month period must be at least 4.5 to 1.00.  The 
Revolving Credit Facility is secured by substantially all the assets of the 
Company.

                                  TERMS OF FACILITY

          II.1   REVOLVING LINE OF CREDIT.  (a) Upon the terms and conditions
and relying on the representations and warranties contained in this Agreement,
the Lenders severally agree, during the Commitment Period, to make Loans, in
immediately available funds at the Applicable Lending Office or the Principal
Office, to or for the benefit of the Borrower, from time to time on any Business
Day designated by the Borrower following receipt by the Agent of a Borrowing
Request; provided, however, no Loan at the time it is made shall exceed the then
existing Available Commitment.

          (b) Subject to the terms of this Agreement, during the Commitment
Period, the Borrower may borrow, repay, and reborrow and convert Loans of one
type or with one Interest Period into Loans of another type or with a different
Interest Period.  Except for prepayments made pursuant to Section 2.10, each
borrowing, conversion, and prepayment of principal of Loans shall be in an
aggregate amount at least equal to $100,000.  Each borrowing, prepayment, or
conversion of or into a Loan of a different type or, in the case of a Fixed Rate
Loan, having a different Interest Period, shall be deemed a separate borrowing,
conversion, or prepayment for purposes of the foregoing, one for each type of
Loan or Interest Period.  Anything in this Agreement to the contrary
notwithstanding, the aggregate principal amount of LIBO Rate Loans having the
same Interest Period shall be at least equal to $100,000; and if any LIBO Rate
Loan would otherwise be in a lesser aggregate principal amount for any period,
such Loan shall be a Floating Rate Loan during such period.

          (c) The Loans shall be made and maintained at the Applicable Lending
Office or the Principal Office and shall be evidenced by the Notes.

          (d) Not later than 3:00 p.m., Central Standard or Daylight Savings
Time, as the case may be, on the date specified for each borrowing, each Lender
shall make available an amount equal to its Percentage Share of the borrowing to
be made on such date to the Agent, at an account designated by the Agent, in
immediately available funds, for the account of the Borrower.  The amount so
received by the Agent shall, subject to the terms and conditions hereof, be made
available to the Borrower in immediately available funds at the Principal
Office.  All Loans by each Lender shall be maintained at the Applicable Lending
Office of such Lender and shall be evidenced by the Note of such Lender.

          (e)  The failure of any Lender to make any Loan required to be made by
it hereunder shall not relieve any other Lender of its obligation to make any
Loan required to be made by it, and no Lender shall be responsible for the
failure of any other Lender to make any Loan.


                                          18
<PAGE>

          (f)  The face amounts of the Notes have been established as an
administrative convenience and do not commit any Lender to advance funds
hereunder in excess of the then current Borrowing Base.

          II.2   LETTER OF CREDIT FACILITY.  (a) Upon the terms and conditions
and relying on the representations and warranties contained in this Agreement,
the Agent, as issuing bank for the Lenders, agrees from the date of this
Agreement until the date which is thirty days prior to the Commitment
Termination Date, to issue on behalf of the Lenders in their respective
Percentage Shares Letters of Credit for the account of the Borrower and to renew
and extend such Letters of Credit.  Letters of Credit shall be issued, renewed,
or extended from time to time on any Business Day designated by the Borrower
following the receipt in accordance with the terms hereof by the Agent of the
written (or oral, confirmed promptly in writing) request by a Responsible
Officer of the Borrower therefor and a Letter of Credit Application.  Letters of
Credit shall be issued in such amounts as the Borrower may request; provided,
however, that (i) no Letter of Credit shall have an expiration date which is
more than 365 days after the issuance thereof or subsequent to the Final
Maturity, (ii) each automatically renewable Letter of Credit shall provide that
it may be terminated by the Agent at its then current expiry date by not less
than 30 days' written notice by the Agent to the beneficiary of such Letter of
Credit, and (iii) the Agent shall not be obligated to issue any Letter of Credit
if (A) the face amount thereof would exceed the Available Commitment, or (B)
after giving effect to the issuance thereof, (I) the L/C Exposure, when added to
the Loan Balance then outstanding, would exceed the lesser of the Maximum
Commitment Amount or the Borrowing Base, or (II) the L/C Exposure would exceed
$5,000,000.

          (b)    Prior to any Letter of Credit Payment in respect of any Letter
of Credit, each Lender shall be deemed to be a participant through the Agent
with respect to the relevant Letter of Credit in the obligation of the Agent, as
the issuer of such Letter of Credit, in an amount equal to the Percentage Share
of such Lender of the maximum amount which is or at any time may become
available to be drawn thereunder.  Upon delivery by such Lender of funds
requested pursuant to Section 2.2(c), such Lender shall be treated as having
purchased a participating interest in an amount equal to such funds delivered by
such Lender to the Agent in the obligation of the Borrower to reimburse the
Agent, as the issuer of such Letter of Credit, for any amounts payable, paid, or
incurred by the Agent, as the issuer of such Letter of Credit, with respect to
such Letter of Credit.

          (c)    Each Lender shall be unconditionally and irrevocably liable,
without regard to the occurrence of any Default or Event of Default, to the
extent of the Percentage Share of such Lender at the time of issuance of each
Letter of Credit, to reimburse, on demand, the Agent, as the issuer of such
Letter of Credit, for the amount of each Letter of Credit Payment under such
Letter of Credit.  Each Letter of Credit Payment shall be deemed to be a
Floating Rate Loan by each Lender to the extent of funds delivered by such
Lender to the Agent with respect to such Letter of Credit Payment and shall to
such extent be deemed a Floating Rate Loan under and shall be evidenced by the
Note of such Lender and shall be payable by the Borrower upon demand by the
Agent.


                                          19
<PAGE>

          (d)     EACH LENDER AGREES TO SEVERALLY INDEMNIFY THE AGENT, AS THE
ISSUER OF EACH LETTER OF CREDIT, AND THE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS-IN-FACT AND AFFILIATES OF THE AGENT (TO THE EXTENT NOT REIMBURSED BY
THE BORROWER AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWER TO DO SO),
RATABLY ACCORDING TO THE PERCENTAGE SHARE OF SUCH LENDER AT THE TIME OF ISSUANCE
OF SUCH LETTER OF CREDIT, FROM AND AGAINST ANY AND ALL LIABILITIES, CLAIMS,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER WHICH MAY AT ANY TIME
(INCLUDING, WITHOUT LIMITATION, ANY TIME FOLLOWING THE PAYMENT AND PERFORMANCE
OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT) BE IMPOSED ON,
INCURRED BY OR ASSERTED AGAINST THE AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT
OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR
AFFILIATES IN ANY WAY RELATING TO OR ARISING OUT OF THIS AGREEMENT OR SUCH
LETTER OF CREDIT OR ANY ACTION TAKEN OR OMITTED BY THE AGENT AS THE ISSUER OF
SUCH LETTER OF CREDIT OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS-IN-FACT OR AFFILIATES UNDER OR IN CONNECTION WITH ANY OF THE
FOREGOING, INCLUDING, WITHOUT LIMITATION, ANY LIABILITIES, CLAIMS, OBLIGATIONS,
LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND
DISBURSEMENTS IMPOSED, INCURRED OR ASSERTED AS A RESULT OF THE NEGLIGENCE,
WHETHER SOLE OR CONCURRENT, OF THE AGENT AS THE ISSUER OF SUCH LETTER OF CREDIT
OR ANY OF ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR
AFFILIATES; PROVIDED THAT NO LENDER (OTHER THAN THE AGENT AS THE ISSUER OF A
LETTER OF CREDIT) SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS,
COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM THE GROSS NEGLIGENCE WHETHER
SOLE OR CONCURRENT OR WILLFUL MISCONDUCT OF THE AGENT AS THE ISSUER OF A LETTER
OF CREDIT.  THE AGREEMENTS IN THIS SECTION 2.2(D) SHALL SURVIVE THE PAYMENT AND
PERFORMANCE OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

          II.3   USE OF LOAN PROCEEDS AND LETTERS OF CREDIT.  (a) on the
Closing Date, each of the Lenders shall pay to Compass an amount equal to the
outstanding principal balance under the Existing Credit Agreement times such
Lender's Percentage Share.  Such Existing Indebtedness under the Existing Credit
Agreement shall be assigned, renewed, extended, and rearranged pursuant to the
terms of this Agreement and the Notes and shall, for all purposes, be deemed a
borrowing hereunder;


                                          20
<PAGE>

                 (b)  proceeds of all subsequent Loans shall be used for
general corporate purposes of the Borrower, including, without limitation, costs
of acquiring, exploring on and developing Oil and Gas Properties and general
working capital needs; and

                 (c)  Letters of Credit shall be used solely for general
corporate purposes of the Borrower; provided, however, no Letter of Credit may
be used in lieu or in support of stay or appeal bonds.  Letters of Credit shall
include Existing Letters of Credit.

          II.4   INTEREST.  Subject to the terms of this Agreement (including,
without limitation, Section 2.18), interest on the Loans shall accrue and be
payable at a rate per annum equal to the Floating Rate for each Floating Rate
Loan and the Adjusted LIBO Rate for each LIBO Rate Loan.  Interest on all
Floating Rate Loans shall be computed on the basis of a year of 365 or 366 days,
as the case may be, and actual days elapsed (including the first day but
excluding the last day) during the period for which payable.  Interest on all
LIBO Rate Loans shall be computed on the basis of a year of 360 days, and actual
days elapsed (including the first day but excluding the last day) during the
period for which payable.  Notwithstanding the foregoing, interest on past-due
principal and, to the extent permitted by applicable law, past-due interest,
shall accrue at the Default Rate, computed on the basis of a year of 365 or 366
days, as the case may be, and actual days elapsed (including the first day but
excluding the last day) during the period for which payable, and shall be
payable upon demand by the Lender at any time as to all or any portion of such
interest.  In the event that the Borrower fails to select the duration of any
Interest Period for any Fixed Rate Loan within the time period and otherwise as
provided herein, such Loan (if outstanding as a Fixed Rate Loan) will be
automatically converted into a Floating Rate Loan on the last day of the then
current Interest Period for such Loan or (if outstanding as a Floating Rate
Loan) will remain as, or (if not then outstanding) will be made as, a Floating
Rate Loan.  Interest provided for herein shall be calculated on unpaid sums
actually advanced and outstanding pursuant to the terms of this Agreement and
only for the period from the date or dates of such advances until repayment.

          II.5   REPAYMENT OF LOANS AND INTEREST.  Accrued and unpaid interest
on each outstanding Floating Rate Loan shall be due and payable monthly
commencing on the first day of May, 1998, and continuing on the first day of
each calendar month thereafter while any Floating Rate Loan remains outstanding,
the payment in each instance to be the amount of interest which has accrued and
remains unpaid in respect of the relevant Loan.  Accrued and unpaid interest on
each outstanding Fixed Rate Loan shall be due and payable on the last day of the
Interest Period for such Fixed Rate Loan and, in the case of any Interest Period
in excess of three months, on the day of the third calendar month following the
commencement of such Interest Period corresponding to the day of the calendar
month on which such Interest Period commenced, the payment in each instance to
be the amount of interest which has accrued and remains unpaid in respect of the
relevant Loan.  The Loan Balance, together with all accrued and unpaid interest
thereon, shall be due and payable at Final Maturity.  At the time of making each
payment hereunder or under the Notes, the Borrower shall specify to the Agent
the Loans or other amounts payable by the Borrower hereunder to which such
payment is to be applied.  In the event the Borrower fails to so specify, or if
an Event of Default


                                          21
<PAGE>

has occurred and is continuing, the Agent may apply such payment as it may elect
in its sole discretion.

          II.6   OUTSTANDING AMOUNTS.  The Loan Balance reflected by the
notations by the Lenders on their records shall be deemed rebuttably presumptive
evidence of the Loan Balance.  The liability for payment of principal and
interest evidenced by the Notes shall be limited to principal amounts actually
advanced and outstanding pursuant to this Agreement and interest on such amounts
calculated in accordance with this Agreement.

          II.7   TIME, PLACE, AND METHOD OF PAYMENTS.  All payments required
pursuant to this Agreement or the Notes shall be made in lawful money of the
United States of America and in immediately available funds, shall be deemed
received by the Lenders on the next Business Day following receipt if such
receipt is after 2:00 p.m., Central Standard or Daylight Savings Time, as the
case may be, on any Business Day, and shall be made to the Agent at the
Principal Office.  Except as provided to the contrary herein, if the due date of
any payment hereunder or under the Notes would otherwise fall on a day which is
not a Business Day, such date shall be extended to the next succeeding Business
Day, and interest shall be payable for any principal so extended for the period
of such extension.

          II.8   PRO RATA TREATMENT; ADJUSTMENTS. (a) Except to the extent
otherwise expressly provided herein, (i) each borrowing made pursuant to this
Agreement shall be from the Lenders pro rata in accordance with their Percentage
Shares, (ii) each payment by the Borrower of Commitment Fees shall be made for
the account of the Lenders pro rata in accordance with their respective
Percentage Shares, (iii) Facility Fees and Letter of Credit Fees shall be made
for the account of the Lenders in accordance with each Lender's Percentage Share
of any increase in the Commitment Amount or Letter of Credit issued,  (iv) each
payment of principal of Loans shall be made for the account of the Lenders pro
rata in accordance with their respective Percentage Shares of the Loan Balance,
and (v) each payment of interest on Loans shall be made for the account of the
Lenders pro rata in accordance with their Percentage Shares of the aggregate
amount of interest due and payable to the Lenders.

          (b)    The Agent shall distribute all payments with respect to the
Obligations to the Lenders promptly upon receipt in like funds as received.  In
the event that any payments made hereunder by the Borrower at any particular
time are insufficient to satisfy in full the Obligations due and payable at such
time, such payments shall be applied (a) first, to fees and expenses due
pursuant to the terms of this Agreement or any other Loan Document, (b) second,
to accrued interest, (c) third, to the Loan Balance, and (d) last, to any other
Obligations.

          (c)    If any Lender (for purposes of this Section, a "BENEFITTED
LENDER") shall at any time receive any payment of all or part of its portion of
the Obligations, or receive any Collateral in respect thereof (whether
voluntarily or involuntarily, by set-off, pursuant to events or proceedings of
the nature referred to in Sections 7.1(f) or 7.1(g), or otherwise) in an amount
greater than such Lender was entitled to receive pursuant to the terms hereof,
such benefitted Lender shall purchase


                                          22
<PAGE>

for cash from the other Lenders such portion of the Obligations of such other
Lenders or shall provide such other Lenders with the benefits of any such
Collateral or the proceeds thereof as shall be necessary to cause such
benefitted Lender to share the excess payment or benefits of such Collateral or
proceeds with each of the Lenders according to the terms hereof.  If all or any
portion of such excess payment or benefits is thereafter recovered from such
benefitted Lender, such purchase shall be rescinded and the purchase price and
benefits returned by such Lender, to the extent of such recovery, but without
interest.  The Borrower agrees that each such Lender so purchasing a portion of
the Obligations of another Lender may exercise all rights of payment (including,
without limitation, rights of set-off) with respect to such portion as fully as
if such Lender were the direct holder of such portion.  If any Lender ever
receives, by voluntary payment, exercise of rights of set-off or banker's lien,
counterclaim, cross-action or otherwise, any funds of the Borrower to be applied
to the Obligations, or receives any proceeds by realization on or with respect
to any Collateral, all such funds and proceeds shall be immediately forwarded to
the Agent for distribution in accordance with the terms of this Agreement.

          II.9   BORROWING BASE DETERMINATIONS.  (a) The Borrowing Base as of
the Closing Date is acknowledged by the Borrower and the Lenders to be
$14,975,000.  Commencing on May 1, 1998, and continuing thereafter on the first
day of each calendar month until the earlier of the date such amount is
redetermined or the Commitment Termination Date, the Scheduled Reduction Amount
shall be $525,000.

          (b) The Borrowing Base and the Scheduled Reduction Amount shall be
redetermined semi-annually by unanimous consent of the Lenders beginning
September 1, 1998, on the basis of information supplied by the Borrower in
compliance with the provisions of this Agreement, including, without limitation,
Reserve Reports, and all other information available to the Lenders.  In
addition, the Lenders shall, in the normal course of business following a
request of the Borrower, redetermine the Borrowing Base; provided, however, the
Lenders shall not be obligated to respond to more than four such requests during
any calendar year, and in no event shall the Lenders be required to redetermine
the Borrowing Base more than once in any three-month period, including, without
limitation, each scheduled semi-annual redetermination provided for above.
Notwithstanding the foregoing, the Lenders may at their discretion and by
unanimous consent redetermine the Borrowing Base and the Scheduled Reduction
Amount at any time and from time to time.

          (c) Upon each determination of the Borrowing Base and the Scheduled
Reduction Amount by the Lenders, the Agent shall notify the Borrower orally
(confirming such notice promptly in writing) of such determination, and the
Borrowing Base and the Scheduled Reduction Amount shall become effective upon
such written notification and shall remain in effect until the next subsequent
determination of the Borrowing Base.

          (d) The Borrowing Base shall represent the determination by the
Lenders, in accordance with the applicable definitions and provisions herein
contained and their customary lending practices for loans of this nature, of the
value, for loan purposes, of the Mortgaged


                                          23
<PAGE>

Properties, plus certain other oil and gas properties to be determined in sole
discretion of the Lenders subject, in the case of any increase in the Borrowing
Base, to the credit approval process of the Lenders.  Furthermore, the Borrower
acknowledges that the determination of the Borrowing Base contains an equity
cushion (market value in excess of loan value), which is acknowledged by the
Borrower to be essential for the adequate protection of the Lenders.  The
Borrowing Base shall be determined in the sole discretion of the Lenders by
using the Lenders' then current engineering and credit standards.

          II.10  MANDATORY PREPAYMENTS.  If at any time the sum of the Loan
Balance and the L/C Exposure exceeds the Borrowing Base then in effect, the
Borrower shall, within 60 days of notice from the Agent of such occurrence, (a)
prepay, or make arrangements acceptable to the Lenders for the prepayment of,
the amount of such excess for application on the Loan Balance, (b) provide
additional Collateral, of character and value satisfactory to the Lenders in
their sole discretion, to secure the amount of such excess by the execution and
delivery to the Lenders of Security Instruments in form and substance
satisfactory to the Lenders, or (c) effect any combination of the alternatives
described in clauses (a) and (b) of this Section and acceptable to the Lenders
in their sole discretion.  In the event that a mandatory prepayment is required
under this Section and the Loan Balance is less than the amount required to be
prepaid, the Borrower shall repay the entire Loan Balance and, in accordance
with the provisions of the relevant Letter of Credit Applications executed by
the Borrower or otherwise to the satisfaction of the Lenders, deposit with the
Agent for the benefit of the Lenders, as additional collateral securing the
Obligations, an amount of cash, in immediately available funds, equal to the L/C
Exposure minus the lesser of the aggregate Commitment Amounts or the Borrowing
Base.  The cash deposited with the Agent for the benefit of the Lenders in
satisfaction of the requirement provided in this Section may be invested, at the
sole discretion of the Lenders and then only at the express direction of the
Borrower as to investment vehicle and maturity (which shall be no later than the
latest expiry date of any then outstanding Letter of Credit), for the account of
the Borrower in cash or cash equivalent investments offered by or through the
Lenders.

          II.11  VOLUNTARY PREPAYMENTS AND CONVERSIONS OF LOANS.   Subject to
applicable provisions of this Agreement, the Borrower shall have the right at
any time or from time to time to prepay Loans and to convert Loans of one type
or with one Interest Period into Loans of another type or with a different
Interest Period; provided, however, that (a) the Borrower shall give the Agent
notice of each such prepayment or conversion of all or any portion of a Fixed
Rate Loan no less than two Business Days prior to prepayment or conversion, (b)
any Fixed Rate Loan may be prepaid or converted only on the last day of an
Interest Period for such Loan, (c) the Borrower shall pay all accrued and unpaid
interest on the amounts prepaid or converted, and (d) no such prepayment or
conversion shall serve to postpone the repayment when due of any Obligation.

          II.12  COMMITMENT FEE.  In addition to interest on the Notes as
provided herein and other fees payable hereunder and to compensate the Lenders
for maintaining funds available, the Borrower shall pay to the Agent, for the
account of the Lenders, in immediately available funds, on the first day of
July, 1998, and on the first day of each third calendar month thereafter during
the


                                          24
<PAGE>

Commitment Period and on the Commitment Termination Date, a fee in the amount
per annum as set forth below, calculated on the basis of a year of 365 or 366
days, as the case may be, and actual days elapsed (including the first day but
excluding the last day), on the average daily amount of the Available Commitment
during the preceding quarterly period as follows:

            of Borrowing Base
</TABLE>

          The Borrowing Base Utilization and the corresponding Commitment Fee
shall be set at the close of each calendar quarter for the next such quarter.

          II.13  FACILITY FEE.  In addition to interest on the Notes as
provided herein and other fees payable hereunder and to compensate the Lenders
for the costs of the extension of credit hereunder, the Borrower shall pay to
the Agent for the account of the Lenders, in immediately available funds, an
initial facility fee in the amount of $58,125.  Such fee shall be paid on the
Closing Date.  In addition, the Borrower shall pay to the Agent for the account
of the Lenders one-quarter percent (1/4%) on any future increase in the
Borrowing Base at the time of such increase.

          II.14  LETTER OF CREDIT FEE.  In addition to interest on the Notes as
provided herein and Commitment Fees and Facility Fees payable hereunder, the
Borrower agrees to pay to the Agent, for the account of the Lenders, on the date
of issuance or renewal of each Letter of Credit, a fee equal to the greater of
(a) $500 or (b) the Applicable Margin in effect at the date of issuance or
renewal, calculated on the basis of a year of 365 or 366 days, as the case may
be, and actual days elapsed (including the first day but excluding the last
day), on the face amount of such Letter of Credit and for the period for which
such Letter of Credit is issued or renewed; provided, however, in the event such
Letter of Credit is canceled prior to its original expiry date or a payment is
made by the Agent for the account of the Lenders with respect to such Letter of
Credit, the Agent and the Lenders shall, within 30 days after such cancellation
or the making of such payment, rebate to the Borrower the unearned portion of
any such fee.  The Borrower also agrees to pay on demand to the Agent, for its
own account as the issuer of the Letters of Credit, its customary letter of
credit transactional fees, including, without limitation, amendment fees,
payable with respect to each Letter of Credit.

          II.15  AGENCY FEE.  The Borrower shall pay to the Agent, for its own
account, all fees owing or which may become owing under the Agency Fee Letter as
provided therein.

          II.16  LOANS TO SATISFY OBLIGATIONS OF BORROWER.  The Lenders may, by
unanimous consent, but shall not be obligated to, make Loans for the benefit of
the Borrower and apply proceeds


                                          25
<PAGE>

thereof to the satisfaction of any condition, warranty, representation, or
covenant of the Borrower contained in this Agreement or any other Loan Document.
Any such Loan shall be evidenced by the Notes and shall be made as a Floating
Rate Loan.

          II.17  SECURITY INTEREST IN ACCOUNTS; RIGHT OF OFFSET.  As security
for the payment and performance of the Obligations, the Borrower hereby
transfers, assigns, and pledges to the Agent, for the benefit of the Lenders,
and grants to the Agent, for the benefit of the Lenders, a security interest in
all funds of the Borrower now or hereafter or from time to time on deposit with
the Agent or any Lender, with such interest of the Lenders to be retransferred,
reassigned, and/or released by the Agent and each Lender, as the case may be, at
the expense of the Borrower upon payment in full and complete performance by the
Borrower of all Obligations.  All remedies as secured party or assignee of such
funds shall be exercisable by the Agent and each Lender upon the occurrence of
any Event of Default, regardless of whether the exercise of any such remedy
would result in any penalty or loss of interest or profit with respect to any
withdrawal of funds deposited in a time deposit account prior to the maturity
thereof.  Furthermore, the Borrower hereby grants to the Agent and each Lender
the right, exercisable at such time as any Obligation shall mature, whether by
acceleration of maturity or otherwise, of offset or banker's lien against all
funds of the Borrower now or hereafter or from time to time on deposit with the
Agent and each Lender, regardless of whether the exercise of any such remedy
would result in any penalty or loss of interest or profit with respect to any
withdrawal of funds deposited in a time deposit account prior to the maturity
thereof.

          II.18  GENERAL PROVISIONS RELATING TO INTEREST.  (a) It is the
intention of the parties hereto to comply strictly with the usury laws of the
State of Texas to the extent applicable to each Lender and the United States of
America.  In this connection, there shall never be collected, charged, or
received on the sums advanced hereunder interest in excess of that which would
accrue at the Highest Lawful Rate.  For purposes of Tex. Fin. Code Ann. Section
303.301 (Vernon 1998), the Borrower agrees that the Highest Lawful Rate shall be
the "indicated (weekly) rate ceiling" as defined in such Article, provided that
the Agent and the Lenders may also rely, to the extent permitted by applicable
laws of the State of Texas or the United States of America, on alternative
maximum rates of interest under other laws of the State of Texas or other states
or the United States of America applicable to the Agent and/or such Lender, if
greater.

          (b) Notwithstanding anything herein or in the Notes to the contrary,
during any Limitation Period, the interest rate to be charged on amounts
evidenced by the Notes shall be the Highest Lawful Rate, and the obligation, if
any, of the Borrower for the payment of fees or other charges deemed to be
interest under applicable law shall be suspended.  During any period or periods
of time following a Limitation Period, to the extent permitted by applicable
laws of the State of Texas or other states or the United States of America, the
interest rate to be charged hereunder shall remain at the Highest Lawful Rate
until such time as there has been paid to the Agent for the account of each
Lender (i) the amount of interest in excess of that accruing at the Highest
Lawful Rate that the Agent and the Lenders would have received during the
Limitation Period had the interest rate

remained at the otherwise applicable rate, and (ii) all interest and fees
otherwise payable to the Agent and the Lenders but for the effect of such
Limitation Period.

          (c) If, under any circumstances, the aggregate amounts paid on the
Notes or under this Agreement or any other Loan Document include amounts which
by law are deemed interest and which would exceed the amount permitted if the
Highest Lawful Rate were in effect, the Borrower stipulates that such payment
and collection will have been and will be deemed to have been, to the greatest
extent permitted by applicable laws of the State of Texas any other applicable
states' laws or the United States of America, the result of mathematical error
on the part of the Borrower and the Agent and the Lenders; and the Agent and the
Lenders shall promptly refund the amount of such excess (to the extent only of
such interest payments in excess of that which would have accrued and been
payable on the basis of the Highest Lawful Rate) upon discovery of such error by
the Agent and the Lenders or notice thereof from the Borrower.  In the event
that the maturity of any Obligation is accelerated, by reason of an election by
the Agent and the Lenders or otherwise, or in the event of any required or
permitted prepayment, then the consideration constituting interest under
applicable laws may never exceed the Highest Lawful Rate; and excess amounts
paid which by law are deemed interest, if any, shall be credited by the Lenders
on the principal amount of the Obligations, or if the principal amount of the
Obligations shall have been paid in full, refunded to the Borrower.

          (d) All sums paid, or agreed to be paid, to the Agent and the Lenders
for the use, forbearance and detention of the proceeds of any advance hereunder
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated, and spread throughout the full term hereof until paid in full so that
the actual rate of interest is uniform but does not exceed the Highest Lawful
Rate throughout the full term hereof.

          II.19  YIELD PROTECTION.  (a) Without limiting the effect of the
other provisions of this Section (but without duplication), the Borrower shall
pay to the Agent and each Lender from time to time such amounts as the Agent and
such Lender may determine are necessary to compensate it for any Additional
Costs incurred by the Agent and such Lender.

          (b) Without limiting the effect of the other provisions of this
Section (but without duplication), the Borrower shall pay to each Lender from
time to time on request such amounts as each Lender may determine are necessary
to compensate each Lender for any costs attributable to the maintenance by each
Lender (or any Applicable Lending Office), pursuant to any Regulatory Change, of
capital in respect of the Commitment, such compensation to include, without
limitation, an amount equal to any reduction of the rate of return on assets or
equity of each Lender (or any Applicable Lending Office) to a level below that
which each Lender (or any Applicable Lending Office) could have achieved but for
such Regulatory Change.

          (c) Without limiting the effect of the other provisions of this
Section (but without duplication), the Borrower shall pay to each Lender the
administrative and re-employment costs customarily charged by Lenders as a
result of:


                                          27
<PAGE>

              (i)   any payment, prepayment, or conversion by the Borrower of a
          Fixed Rate Loan on a date other than the last day of an Interest
          Period for such Loan; or

             (ii)   any failure by the Borrower to borrow a Fixed Rate Loan from
          the Lenders on the date for such borrowing specified in the relevant
          Borrowing Request;

such compensation to include, without limitation, with respect to any LIBO Rate
Loan, an amount equal to the excess, if any and only to the extent actually
incurred by such Lender, of (A) the amount of interest which would have accrued
on the principal amount so paid, prepaid, converted, or not borrowed for the
period from the date of such payment, prepayment, conversion, or failure to
borrow to the last day of the then current Interest Period for such Loan (or, in
the case of a failure to borrow, the Interest Period for such Loan which would
have commenced on the date of such failure to borrow) at the applicable rate of
interest for such Loan provided for herein over (B) the interest component (as
reasonably determined by the Lenders) of the amount (as reasonably determined by
the Agent and such Lender) the Agent and such Lender would have bid in the
London interbank market for Dollar deposits of amounts comparable to such
principal amount and maturities comparable to such period.

          (d) Determinations by the Agent and any Lender for purposes of this
Section of the effect of any Regulatory Change on capital maintained, their
costs or rate of return, maintaining Loans, their obligation to make Loans or on
amounts receivable by it in respect of Loans or such obligations, and the
additional amounts required to compensate the Agent and the Lenders under this
Section shall be conclusive, absent manifest error, provided that such
determinations are made on a reasonable basis.  The Agent and such Lender shall
furnish the Borrower with a certificate setting forth in reasonable detail the
basis and amount of increased costs incurred or reduced amounts receivable as a
result of any such event, and the statements set forth therein shall be
conclusive, absent manifest error.  The Agent and such Lender shall (i) notify
the Borrower, as promptly as practicable after the Lenders obtain knowledge of
any Additional Costs or other sums payable pursuant to this Section and
determine to request compensation therefor, of any event occurring after the
Closing Date which will entitle the Agent and such Lender to compensation
pursuant to this Section; provided that the Borrower shall not be obligated for
the payment of any Additional Costs or other sums payable pursuant to this
Section to the extent such Additional Costs or other sums accrued more than 30
days prior to the date upon which the Borrower was given such notice; and (ii)
designate a different Applicable Lending Office for the Loans of the Lenders
affected by such event if such designation will avoid the need for or reduce the
amount of such compensation.  If the Agent or any Lender requests compensation
from the Borrower under this Section, the Borrower may, by notice to the Agent
and any Lender, require that the Loans by the Lenders of the type with respect
to which such compensation is requested be converted into Floating Rate Loans in
accordance with Section 2.11.  Any compensation requested by the Lenders
pursuant to this Section shall be due and payable to the Lenders within five
days of delivery of any such notice by the Lenders to the Borrower.


                                          28
<PAGE>

          (e) Each Lender agrees that it shall not request, and the Borrower
shall not be obligated to pay, any Additional Costs or other sums payable
pursuant to this Section unless similar additional costs and other sums payable
are also generally assessed by the Lenders against other customers of such
Lenders similarly situated where such customers are subject to documents
providing for such assessment.

          II.20  LIMITATION ON TYPES OF LOANS.  Anything herein to the contrary
notwithstanding, no more than six separate Loans shall be outstanding at any one
time, with, for purposes of this Section, all Floating Rate Loans constituting
one Loan and all LIBO Rate Loans for the same Interest Period constituting one
Loan.  Anything herein to the contrary notwithstanding, if, on or prior to the
determination of any interest rate for any LIBO Rate Loan for any Interest
Period therefor:

          (a) the Agent determines (which determination shall be conclusive)
     that quotations of interest rates for the deposits referred to in the
     definition of "LIBO Rate" in Section 1.2 are not being provided in the
     relevant amounts or for the relevant maturities for purposes of determining
     the rate of interest for such Loan as provided in this Agreement; or

          (b) the Agent determines (which determination shall be conclusive)
     that the rates of interest referred to in the definition of "LIBO Rate" in
     Section 1.2 upon the basis of which the rate of interest for such Loan for
     such Interest Period is to be determined do not accurately reflect the cost
     to the Lender of making or maintaining such Loan for such Interest Period,

then the Agent shall give the Borrower prompt notice thereof; and so long as
such condition remains in effect, the Lenders shall be under no obligation to
make LIBO Rate Loans or to convert Loans of any other type into LIBO Rate Loans,
and the Borrower shall, on the last day of the then current Interest Period for
each outstanding LIBO Rate Loan, either prepay such LIBO Rate Loan or convert
such Loan into another type of Loan in accordance with Section 2.11.  Before
giving such notice pursuant to this Section, the Agent will designate a
different available Applicable Lending Office for LIBO Rate Loans or take such
other action as the Borrower may request if such designation or action will
avoid the need to suspend the obligation of the Lenders to make LIBO Rate Loans
hereunder and will not, in the unanimous opinion of the Lenders, be
disadvantageous to the Lenders.

          II.21  ILLEGALITY.  Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to (a) honor its obligation to make any type of Fixed
Rate Loans hereunder, or (b) maintain any type of Fixed Rate Loans hereunder,
then such Lender shall promptly notify the Agent and the  Borrower thereof; and
the obligation of such Lender hereunder to make such type of Fixed Rate Loans
and to convert other types of Loans into Fixed Rate Loans of such type shall be
suspended until such time as such Lender may again make and maintain Fixed Rate
Loans of such type, and the outstanding Fixed Rate Loans of such type shall be
converted into Floating Rate Loans in accordance with Section 2.11.  Before


                                          29
<PAGE>

giving such notice pursuant to this Section, such Lender will designate a
different available Applicable Lending Office for Fixed Rate Loans or take such
other action as the Borrower may request if such designation or action will
avoid the need to suspend the obligation of the Lenders to make Fixed Rate Loans
and will not, in the opinion of any Lender, be disadvantageous to the Lenders.

          II.22  REGULATORY CHANGE.  In the event that by reason of any
Regulatory Change, any Lender (a) incurs Additional Costs based on or measured
by the excess above a specified level of the amount of a category of deposits or
other liabilities of such Lender which includes deposits by reference to which
the interest rate on any Fixed Rate Loan is determined as provided in this
Agreement or a category of extensions of credit or other assets of such Lender
which includes any Fixed Rate Loan, or (b) becomes subject to restrictions on
the amount of such a category of liabilities or assets which it may hold, then,
at the election of such Lender with notice to the Agent and the Borrower, the
obligation of the Lender to make such Fixed Rate Loans and to convert Floating
Rate Loans into such Fixed Rate Loans shall be suspended until such time as such
Regulatory Change ceases to be in effect, and all such outstanding Fixed Rate
Loans shall be converted into Floating Rate Loans in accordance with Section
2.11.

          II.23  LIMITATIONS ON INTEREST PERIODS.  Each Interest Period
selected by the Borrower (a) which commences on the last Business Day of a
calendar month (or, with respect to any LIBO Rate Loan, any day for which there
is no numerically corresponding day in the appropriate subsequent calendar
month) shall end on the last Business Day of the appropriate subsequent calendar
month, (b) which would otherwise end on a day which is not a Business Day shall
end on the next succeeding Business Day (or, if such next succeeding Business
Day falls in the next succeeding calendar month, on the next preceding Business
Day), (c) which would otherwise commence before and end after Final Maturity
shall end on Final Maturity, and (d) shall have a duration of not less than one
month, as to any LIBO Rate Loan, and, if any Interest Period would otherwise be
a shorter period, the relevant Loan shall be a Floating Rate Loan during such
period.

          II.24  LETTERS IN LIEU OF TRANSFER ORDERS.  The Agent agrees that
none of the letters in lieu of transfer or division orders provided by the
Borrower pursuant to Section 3.1(f)(iii) or Section 5.7 will be sent to the
addressees thereof prior to the occurrence of an Event of Default, at which time
the Agent may, at its option and in addition to the exercise of any of its other
rights and remedies, send any or all of such letters.

          II.25  POWER OF ATTORNEY.  The Borrower hereby designates the Agent
as its agent and attorney-in-fact, to act in its name, place, and stead for the
purpose of completing and, upon the occurrence of an Event of Default,
delivering any and all of the letters in lieu of transfer orders delivered by
the Borrower to the Agent pursuant to Section 3.1(f)(iii) or Section 5.7,
including, without limitation, completing any blanks contained in such letters
and attaching exhibits thereto describing the relevant Collateral.  The Borrower
hereby ratifies and confirms all that the Agent shall lawfully do or cause to be
done by virtue of this power of attorney and the rights granted with respect to
such power of attorney.  This power of attorney is coupled with the interests of
the Agent in the


                                          30
<PAGE>

Collateral, shall commence and be in full force and effect as of the Closing
Date and shall remain in full force and effect and shall be irrevocable so long
as any Obligation remains outstanding or unpaid or any Commitment exists.  The
powers conferred on the Agent by this appointment are solely to protect the
interests of the Agent and the Lenders under the Loan Documents and shall not
impose any duty upon the Agent to exercise any such powers.  The Agent shall be
accountable only for amounts that it actually receives as a result of the
exercise of such powers and shall not be responsible to the Borrower or any
other Person for any act or failure to act with respect to such powers, except
for gross negligence or willful misconduct.

                            REPRESENTATIONS AND WARRANTIES


                                          35
<PAGE>

          To induce the Agent and the Lenders to enter into this Agreement and
to make the Loans and issue, or participate in the issuance of, Letters of
Credit, the Borrower represents and warrants to the Agent and the Lenders (which
representations and warranties shall survive the delivery of the Notes) that:

          IV.1   DUE AUTHORIZATION.  The execution and delivery by the Borrower
of this Agreement and the borrowings hereunder, the execution and delivery by
the Borrower of the Notes, the repayment of the Notes and interest and fees
provided for in the Notes and this Agreement, the execution and delivery of the
Security Instruments by the Borrower and the performance of all obligations of
the Borrower under the Loan Documents are within the power of the Borrower, have
been duly authorized by all necessary corporate action by the Borrower, and do
not and will not to our knowledge, (a) require the consent of any Governmental
Authority, (b) contravene or conflict with any Requirement of Law, (c)
contravene or conflict with any indenture, instrument, or other agreement to
which the Borrower is a party or by which any Property of the Borrower may be
presently bound or encumbered, or (d) result in or require the creation or
imposition of any Lien in, upon or of any Property of the Borrower under any
such indenture, instrument, or other agreement, other than the Loan Documents.

          IV.2   CORPORATE EXISTENCE.  The Borrower is a corporation duly
organized, legally existing, and in good standing under the laws of its state of
incorporation and is duly qualified as a foreign corporation and are in good
standing in all jurisdictions wherein the ownership of Property or the operation
of its business necessitates same, other than those jurisdictions wherein the
failure to so qualify will not have a Material Adverse Effect.

          IV.3   VALID AND BINDING OBLIGATIONS.  All Loan Documents, when duly
executed and delivered by the Borrower, will be the legal, valid, and binding
obligations of the Borrower, enforceable against the Borrower in accordance with
their respective terms.

          IV.4   SECURITY INSTRUMENTS.  The provisions of each Security
Instrument are effective to create in favor of the Agent for the benefit of the
Lenders, a legal, valid, and enforceable Lien in all right, title, and interest
of the Borrower in the Collateral described therein, which Liens, assuming the
accomplishment of recording and filing in accordance with applicable laws prior
to the intervention of rights of other Persons, shall constitute fully perfected
first-priority Liens on all right, title, and interest of the Borrower in the

questioning the validity or effectiveness of any such Intellectual Property; and
the Borrower knows of no valid basis for any such claim.  The use of such
Intellectual Property by the Borrower does not infringe on the rights of any

Lender, a Lien against the rights of such Subsidiary or other Affiliate of the
Borrower under each Commodity Hedge Agreement into which it enters, whether then
existing or thereafter arising.

          V.21   PAYMENT OF COMMODITY HEDGE OBLIGATIONS.  Pay, and cause each
Subsidiary or other Affiliate of the Borrower which is a party to a Commodity
Hedge Agreement to pay, all Commodity Hedge Obligations as they become due and
in any event within sixty (60) days from the date the relevant Commodity Hedge
Obligation becomes due.

          V.22   (A) OBLIGATIONS JOINT AND SEVERAL AND UNCONDITIONAL.  The
obligations of each Borrower under this Agreement and the Notes that are stated
to be obligations of both Borrowers are joint and several and absolute and
unconditional irrespective of the value, genuineness, validity, regularity or
enforceability of the obligations of the other Borrower under this Agreement,
the Notes or any other agreement or instrument referred to herein or therein
(collectively, the "OTHER BORROWER OBLIGATIONS"), or any substitution, release
or exchange of any other guarantee of or security for any of the Other Borrower
Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section 5.22 that the obligations of each Borrower
hereunder shall be absolute and unconditional under any and all circumstances.
Without limiting the generality of the foregoing, it is agreed that the
occurrence of any one or more of the following shall not affect the liability of
either Borrower under this Agreement, the Notes or any other agreement referred
to herein or therein:

     (a)  at any time or from time to time, without notice to either Borrower,
     the time for any performance of or compliance with any of the Other
     Borrower Obligations shall be extended, or such performance or compliance
     shall be waived;


                                          46
<PAGE>

     (b)  any of the acts mentioned in any of the provisions of this Agreement
     or the Notes or any other agreement or instrument referred to herein or
     therein shall be done or omitted;

     (c)  the maturity of any of the Other Borrower Obligations shall be
     accelerated, or any of the Other Borrower Obligations shall be modified,
     supplemented or amended in any respect, or any right under this Agreement
     or the Notes or any other agreement or instrument referred to herein or
     therein shall be waived or any other guarantee of any of the Other Borrower
     Obligations or any security therefor shall be released or exchanged in
     whole or in part or otherwise dealt with; or

     (d)  any lien or security interest granted to, or in favor of, the Agent or
     any Lender or Lenders as security for any of the Other Borrower Obligations
     shall fail to be perfected.

     Each Borrower hereby expressly waives, with respect to the Other Borrower
Obligations diligence, presentment, demand of payment, protest  and all notices
whatsoever, and any requirement that the Agent or any Lender exhaust any right,
power or remedy or proceed against the other Borrower under this Agreement or
the Notes or any other agreement or instrument referred to herein or therein, or
against any other Person under any other guarantee of, or security for, any of
the Other Borrower Obligations.

     (B)  REINSTATEMENT.  The obligations of a Borrower under this Section 5.22
shall be automatically reinstated if and to the extent that for any reason any
payment by or on behalf of the other Borrower in respect of the Other Borrower
Obligations is rescinded or must be otherwise restored by any holder of any of
the Other Borrower Obligations, whether as a result of any proceedings in a
bankruptcy or reorganization or otherwise, and each Borrower agrees that it will
indemnify the Agent and each Lender on demand for all reasonable costs and
expenses (including, without limitation, fees of counsel) incurred by the Agent
or such Lender in connection with such rescission or restoration.

     (C)  SUBROGATION.  Each Borrower hereby agrees that until the payment and
satisfaction in full of all Other Borrower Obligations and the expiration and
termination of the Commitments of the Lenders under this Agreement it shall not
exercise any right or remedy arising by reason of any performance by it of any
of its obligations hereunder, whether by subrogation or otherwise, against the
Other Borrower Obligations or any security for any of the Other Borrower
Obligations.

     (D)  REMEDIES.  Each Borrower agrees that, as between such Borrower and the
Lenders, the obligations of the other Borrower under this Agreement and the
Notes may be declared to be forthwith due and payable as provided in Article VII
hereof (and shall be deemed to have become automatically due and payable in the
circumstances provided in Article VII) notwithstanding any stay, injunction or
other prohibition preventing such declaration (or such obligations from being


                                          47
<PAGE>

deemed to have become automatically due and payable), such obligations (whether
or not due and payable by such other Borrower) shall forthwith become due and
payable by such Borrower.

     (E)  Notwithstanding any provision to the contrary contained herein, in any
of the Notes or any other agreement or instrument referred to herein or therein,
to the extent the joint obligations of the Borrowers would be adjudicated to be
invalid or unenforceable for any reason (including, without limitation, because
of applicable state or federal law relating to fraudulent conveyances or
transfers) then the aggregate obligations of each Borrower hereunder and under
the Notes and all other agreements and instruments referred to herein or therein
shall be limited to the maximum amount that is permissible under applicable law
(whether federal or state and including, with limitation, the federal Bankruptcy
Code).

          VIII.2    WAIVERS, AMENDMENTS.  The provisions of this Agreement and
of each other Loan Document may from time to time be amended, modified or
waived, if such amendment, modification, or waiver is in writing and consented
to by the Borrower and the Required Lenders; provided, however, that no such
amendment, modification or waiver would: (a) modify any requirement hereunder
that any particular action be taken by all of the Lenders or by the Required
Lenders unless consented to by each Lender; (b) modify this Section 8.2, change
the definition of "Required Lenders", or change the Commitment Amount or
Percentage Share of any Lender, reduce the fees described in Article II, extend
the Commitment Termination Date or Final Maturity, release any Security
Instrument or Lien, or initiate any foreclosure, enforcement or collection
procedure without the consent of each Lender; (c) extend the due date for, (or
reduce the amount of any scheduled repayment or prepayment of principal of or
interest on any Loan) without the consent of the holder of that Note evidencing
such Loan; (d) affect, adversely the interests, rights, or obligations of the
Agent without the consent of the Agent; or (e) to modify the Borrowing Base or
modify the Scheduled Reduction Amount.

          VIII.3    DELEGATION OF DUTIES.  The Agent may execute any of its
duties under this Agreement and the other Loan Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties.  The Agent shall not be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it with
reasonable care.

          VIII.4    EXCULPATORY PROVISIONS.  Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(a) required to initiate or conduct any litigation or collection proceedings
hereunder, except with the concurrence of the Lenders and contribution by each
Lender of its Percentage Share of costs reasonably expected by the Agent to be
incurred in connection therewith, (b) liable for any action lawfully taken or
omitted to be taken


                                          55
<PAGE>

by it or such Person under or in connection with this Agreement or any other
Loan Document (except for gross negligence or willful misconduct of the Agent or
such Person), or (c) responsible in any manner to any Lender for any recitals,
statements, representations or warranties made by the Borrower or any officer
thereof contained in this Agreement or any other Loan Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, this Agreement or any
other Loan Document, or for the sufficiency, accuracy, or completeness of any
materials provided by the Agent, or the failure of the Agent to provide any
materials or disclose any matter to any Lender except as may be expressly
required herein, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document or
for any failure of the Borrower to perform its obligations hereunder or
thereunder.  The Agent shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of the Borrower.

          VIII.5    RELIANCE BY AGENT.  The Agent shall be entitled to rely, and
shall be fully protected in relying, upon any Note, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document or conversation believed by
it to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including,
without limitation, counsel to the Borrower), independent accountants and other
experts selected by the Agent.  The Agent may deem and treat the payee of any
Note as the owner thereof for all purposes unless and until an executed Lender
Assignment Agreement shall have been received by the Agent.  The Agent shall be
fully justified in failing or refusing to take any action under this Agreement
or any other Loan Document unless it shall first receive such advice or
concurrence of the Lenders as it deems appropriate and contribution by each
Lender of its Percentage Share of costs reasonably expected by the Agent to be
incurred in connection therewith.  The Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement and the
other Loan Documents in accordance with a request of the Lenders.  Such request
and any action taken or failure to act pursuant thereto shall be binding upon
the Lenders and all future holders of the Notes.  In no event shall the Agent be
required to take any action that exposes the Agent to personal liability or that
is contrary to any Loan Document or applicable Requirement of Law.

          VIII.6    NOTICE OF DEFAULT.  The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default unless
the Agent has received notice from a Lender or the Borrower referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default."  In the event that the Agent receives such a
notice, the Agent shall promptly give written notice thereof to the Lenders.
The Agent shall take such action with respect to such Default or Event of
Default as shall be reasonably directed by the Lenders; provided that unless and
until the Agent shall have received such directions, subject to the provisions
of Section 7.2, the Agent may (but shall not be obligated to) take such action,
or refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interests of the Lenders.  In the
event that the officer of the Agent primarily responsible


                                          56
<PAGE>

for the lending relationship with the Borrower or the officer of any Lender
primarily responsible for the lending relationship with the Borrower becomes
aware that a Default or Event of Default has occurred and is continuing, the
Agent or such Lender, as the case may be, shall use its good faith efforts to
inform the other Lenders and/or the Agent, as the case may be, promptly of such
occurrence.  Notwithstanding the preceding sentence, failure to comply with the
preceding sentence shall not result in any liability to the Agent or any Lender.

          VIII.7    NON-RELIANCE ON AGENT AND OTHER LENDERS.  Each Lender
expressly acknowledges that neither the Agent nor any other Lender nor any of
their respective officers, directors, employees, agents, attorneys-in-fact or
affiliates has made any representation or warranty to such Lender and that no
act by the Agent or any other Lender hereafter taken, including any review of
the affairs of the Borrower, shall be deemed to constitute any representation or
warranty by the Agent or any Lender to any other Lender.  Each Lender represents
to the Agent that it has, independently and without reliance upon the Agent or
any other Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, condition (financial and otherwise) and creditworthiness
of the Borrower and the value of the Collateral and other Properties of the
Borrower and has made its own decision to enter into this Agreement.  Each
Lender also represents that it will, independently and without reliance upon the
Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigation as it deems necessary
to inform itself as to the business, operations, property, condition (financial
and otherwise) and creditworthiness of the Borrower and the value of the
Collateral and other Properties of the Borrower.  Except for notices, reports
and other documents expressly required to be furnished to the Lenders by the
Agent hereunder, the Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the business,
operations, property, condition (financial and otherwise), or creditworthiness
of the Borrower or the value of the Collateral or other Properties of the
Borrower which may come into the possession of the Agent or any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates.

          VIII.8    INDEMNIFICATION.  EACH LENDER AGREES TO SEVERALLY INDEMNIFY
THE AGENT AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT AND
AFFILIATES (TO THE EXTENT NOT REIMBURSED BY THE BORROWER AND WITHOUT LIMITING
THE OBLIGATION OF THE BORROWER TO DO SO), RATABLY AND ACCORDING TO THE
PERCENTAGE SHARE OF SUCH LENDER, FROM AND AGAINST ANY AND ALL LIABILITIES,
CLAIMS, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS,
COSTS, EXPENSES AND DISBURSEMENTS OF ANY KIND WHATSOEVER WHICH MAY AT ANY TIME
(INCLUDING, WITHOUT LIMITATION, ANY TIME FOLLOWING THE PAYMENT AND PERFORMANCE
OF ALL OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT) BE IMPOSED ON,
INCURRED BY OR ASSERTED AGAINST THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS,
EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES IN ANY WAY RELATING TO OR
ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY OTHER DOCUMENT
CONTEMPLATED OR REFERRED TO HEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
ANY ACTION TAKEN OR OMITTED BY THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS,
EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES UNDER OR IN CONNECTION WITH
ANY OF THE FOREGOING, INCLUDING, WITHOUT LIMITATION, ANY LIABILITIES, CLAIMS,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
EXPENSES AND DISBURSEMENTS IMPOSED, INCURRED OR ASSERTED AS A RESULT OF THE
NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF THE AGENT OR ANY OF ITS OFFICERS,
DIRECTORS, EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES; PROVIDED THAT NO
LENDER SHALL BE LIABLE FOR THE PAYMENT OF ANY PORTION OF SUCH LIABILITIES,
OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
EXPENSES OR DISBURSEMENTS RESULTING FROM THE GROSS NEGLIGENCE, SOLE OR
CONCURRENT OR WILLFUL MISCONDUCT OF THE AGENT OR ANY OF ITS OFFICERS, DIRECTORS,
EMPLOYEES, AGENTS, ATTORNEYS-IN-FACT OR AFFILIATES.  THE AGREEMENTS IN THIS
SECTION SHALL SURVIVE THE PAYMENT AND PERFORMANCE OF ALL OBLIGATIONS AND THE
TERMINATION OF THIS AGREEMENT.

          VIII.9    RESTITUTION.  Should the right of the Agent or any Lender to
realize funds with respect to the Obligations be challenged and any application
of such funds to the Obligations be reversed, whether by Governmental Authority
or otherwise, or should the Borrower otherwise be entitled to a refund or return
of funds distributed to the Lenders in connection with the Obligations, the
Agent or such Lender, as the case may be, shall promptly notify the Lenders of
such fact.  Not later than Noon, Central Standard or Daylight Savings Time, as
the case may be, of the Business Day following such notice, each Lender shall
pay to the Agent an amount equal to the ratable share of such Lender of the
funds required to be returned to the Borrower.  The ratable share of each Lender
shall be determined on the basis of the percentage of the payment all or a
portion of which is


                                          58
<PAGE>

required to be refunded originally distributed to such Lender, if such
percentage can be determined, or, if such percentage cannot be determined, on
the basis of the Percentage Share of such Lender.  The Agent shall forward such
funds to the Borrower or to the Lender required to return such funds.  If any
such amount due to the Agent is made available by any Lender after Noon, Central
Standard or Daylight Savings Time, as the case may be, of the Business Day
following such notice, such Lender shall pay to the Agent (or the Lender
required to return funds to the Borrower, as the case may be) for its own
account interest on such amount at a rate equal to the Federal Funds Rate for
the period from and including the date on which restitution to the Borrower is
made by the Agent (or the Lender required to return funds to the Borrower, as
the case may be) to but not including the date on which such Lender failing to
timely forward its share of funds required to be returned to the Borrower shall
have made its ratable share of such funds available.

          VIII.10   AGENT IN ITS INDIVIDUAL CAPACITY.  The Agent and its
affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Borrower as though the Agent were not the agent
hereunder.  With respect to any Note issued to the Lender serving as the Agent,
the Agent shall have the same rights and powers under this Agreement as a Lender
and may exercise such rights and powers as though it were not the Agent.  The
terms "Lender" and "Lenders" shall include the Agent in its individual capacity.

          VIII.11   SUCCESSOR AGENT.  The Agent may resign as Agent upon thirty
days' notice to the Lenders and the Borrower.  If the Agent shall resign as
Agent under this Agreement and the other Loan Documents, or if the Agent shall
assign all of its obligations, then the Lenders shall appoint from among the
Lenders a successor agent for the Lenders, whereupon such successor agent shall
succeed to the rights, powers and duties of the Agent.  The term "Agent" shall
mean such successor agent effective upon its appointment.  The rights, powers,
and duties of the former Agent as Agent shall be terminated, without any other
or further act or deed on the part of such former Agent or any of the parties to
this Agreement or any holders of the Notes.  After the removal or resignation of
any Agent hereunder as Agent, the provisions of this Article VIII and Sections
5.16 and 5.19, shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Agent under this Agreement and the other Loan
Documents.

          VIII.12   APPLICABLE PARTIES.  The provisions of this Article are
solely for the benefit of the Agent and the Lenders, and the Borrower shall not
have any rights as a third party beneficiary or otherwise under any of the
provisions of this Article.  In performing functions and duties hereunder and
under the other Loan Documents, the Agent shall act solely as the agent of the
Lenders and does not assume, nor shall it be deemed to have assumed, any
obligation or relationship of trust or agency with or for the Borrower or any
legal representative, successor, and assign of the Borrower.


                                      ARTICLE IX

                                    MISCELLANEOUS


                                          59
<PAGE>

          IX.1   ASSIGNMENTS; PARTICIPATIONS.  Each Lender may assign or sell
participations in its Loans and Commitments to one or more other Persons in
accordance with this Section 9.1.

          (a) ASSIGNMENTS.  Any Lender:

          (i) with the written consent of both the Borrower and the Agent (which
          consent shall not be unreasonably delayed or withheld), may at any
          time, assign and delegate to one or more commercial banks or other
          financial institutions, and

          (ii) with notice to the Borrower and the Agent, but without the
          consent of the Borrower or the Agent, may assign and delegate to any
          of its affiliates or to any other Lender

(each Person described in (i) or (ii) above as being the Person to whom such
assignment and delegation is to be made, being hereinafter referred to as an
"ASSIGNEE LENDER"), all or any fraction of such Lender's total Loans and
Commitments (which assignment and delegation shall be of a constant, and not a
varying percentage, of all the assigning Lender's Loans and Commitments), in a
minimum aggregate amount of $1,000,000 of such Lender's Percentage Share of the
Maximum Commitment Amount, if less; provided, however, that such Assignee Lender
will comply with all the provisions of this Agreement, and further, provided,
however, that the Borrower and the Agent shall be entitled to continue to deal
solely and directly with such assigning Lender in connection with the interests
so assigned and delegated to an Assignee Lender until:

          (iii) written notice of such assignment and delegation together with
          payment instructions, addresses and related information with respect
          to such Assignee Lender, shall have been given to the Borrower and the
          Agent by such Lender and such Assignee Lender,

          (iv) such Assignee Lender shall have executed and delivered to the
          Borrower and the Agent a Lender Assignment Agreement, accepted by the
          Borrower and the Agent, and substantially in the form attached hereto
          as Exhibit VI, and

          (v) the processing fees described below shall have been paid.

          From and after the date that the Borrower and the Agent accept such
Lender Assignment Agreement, (a) the Assignee Lender thereunder shall be deemed
automatically to have become a party hereto and to the extent that rights and
obligations hereunder have been assigned and delegated to such Assignee Lender
in connection with such Lender Assignment Agreement, shall have the rights and
obligations of a Lender hereunder and under the  other Loan Documents, and (b)
the Assignor Lender, to the extent that rights and obligations hereunder have
been assigned and


                                          60
<PAGE>

delegated by it in connection with such Lender Assignment Agreement, shall be
released from its obligations hereunder and under the other Loan Documents.
Within five Business Days after its receipt of notice that the Agent has
received an executed Lender Assignment Agreement, the Borrower shall execute and
deliver to the Agent (for delivery to the relevant Assignee Lender) new Notes
evidencing such Assignee Lender's assigned Loans and Commitments and, if the
assignor Lender has retained Loans and Commitments hereunder, replacement Notes
in the principal amount of the Loans and Commitments retained by the assignor
Lender hereunder (such Notes to be in exchange for, but not in payment of, those
Notes then held by such assignor Lender).  Each such Note shall be dated the
date of the predecessor Notes.  The assignor Lender shall mark the predecessor
Notes "exchanged" and deliver them to the Borrower.  Accrued interest on that
part of the predecessor Notes evidenced by the new Notes, and accrued fees,
shall be paid as provided in the Lender Assignment Agreement.  Accrued interest
on that part of the predecessor Notes evidenced by the replacement Notes shall
be paid to the assignor Lender.  Accrued interest and accrued fees shall be paid
at the same time or times provided in the predecessor Notes and in this
Agreement.  Such Assignor Lender or such Assignee Lender must also pay a
processing fee in the amount of $3,000 to the Agent upon delivery of any Lender
Assignment Agreement.  Any attempted assignment and delegation not made in
accordance with this Section 9.1 shall be null and void.

          (b) PARTICIPATIONS.  Any Lender may, at any time and without necessity
for the consent of the Agent or the Borrower, sell to one or more commercial
banks (each of such commercial banks being herein called a "PARTICIPANT")
participating interests in any of the Loans, Commitments, or other interests of
such Lender hereunder; provided, however, that (a) no participation contemplated
in this Section 9.1 shall relieve such Lender from its Commitments or its other
obligations hereunder or under any other Loan Document, (b) such Lender shall
remain solely responsible for the performance of its Commitments and such other
obligations, (c) the Borrower and the Agent shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and each of the other Loan Documents, (d) no
Participant shall be entitled to require such Lender to take or refrain from
taking any action hereunder or under any other Loan Document.

          IX.2   SURVIVAL OF REPRESENTATIONS, WARRANTIES, AND COVENANTS.  All
representations and warranties of the Borrower and all covenants and agreements
herein made shall survive the execution and delivery of the Notes and the
Security Instruments and shall remain in force and effect so long as any
Obligation is outstanding or any Commitment exists.

          IX.3   NOTICES AND OTHER COMMUNICATIONS.  Except as to oral notices
expressly authorized herein, which oral notices shall be confirmed in writing,
all notices, requests, and communications hereunder shall be in writing
(including by telecopy).  Unless otherwise expressly provided herein, any such
notice, request, demand, or other communication shall be deemed to have been
duly given or made when delivered by hand, or, in the case of delivery by mail,

no concurrent telecopy notice is given, three Business Days after deposited in
the mail, certified mail, return receipt requested, postage

          Any party may, by proper written notice hereunder to the others,

be sent.

          IX.4   PARTIES IN INTEREST.  Subject to the restrictions on changes
in corporate structure set forth in Section 6.9 and other applicable
restrictions contained herein, all covenants and agreements herein contained by
or on behalf of the Borrower or the Agent and each Lender shall be


                                          62
<PAGE>

binding upon and inure to the benefit of the Borrower or the Agent and each
Lender, as the case may be, and their respective legal representatives,
successors, and assigns.

          IX.5   RIGHTS OF THIRD PARTIES.  All provisions herein are imposed
solely and exclusively for the benefit of the Agent and each Lender and the
Borrower.  No other Person shall have any right, benefit, priority, or interest
hereunder or as a result hereof or have standing to require satisfaction of
provisions hereof in accordance with their terms, and any or all of such
provisions may be freely waived in whole or in part by the Agent or the Lenders
at any time if in their sole discretion they deem it advisable to do so.

          IX.6   RENEWALS; EXTENSIONS.  All provisions of this Agreement
relating to the Notes shall apply with equal force and effect to each promissory
note hereafter executed which in whole or in part represents a renewal or
extension of any part of the Indebtedness of the Borrower under this Agreement,
the Notes, or any other Loan Document.

          IX.7   NO WAIVER; RIGHTS CUMULATIVE.  No course of dealing on the
part of the Agent or the Lenders, their officers or employees, nor any failure
or delay by the Agent or the Lenders with respect to exercising any of their
rights under any Loan Document shall operate as a waiver thereof.  The rights of
the Agent and each Lender under the Loan Documents shall be cumulative and the
exercise or partial exercise of any such right shall not preclude the exercise
of any other right.  The making of any Loan shall not constitute a waiver of any
of the covenants, warranties, or conditions of the Borrower contained herein.
In the event the Borrower is unable to satisfy any such covenant, warranty, or
condition, the making of any Loan shall not have the effect of precluding the
Agent and each Lender from thereafter declaring such inability to be an Event of
Default as hereinabove provided.

          IX.8   SURVIVAL UPON UNENFORCEABILITY.  In the event any one or more
of the provisions contained in any of the Loan Documents or in any other
instrument referred to herein or executed in connection with the Obligations
shall, for any reason, be held to be invalid, illegal, or unenforceable in any
respect, such invalidity, illegality, or unenforceability shall not affect any
other provision of any Loan Document or of any other instrument referred to
herein or executed in connection with such Obligations.

          IX.9   AMENDMENTS; WAIVERS.  Neither this Agreement nor any provision
hereof may be amended, waived, discharged, or terminated orally, but only by an
instrument in writing signed by the party against whom enforcement of the
amendment, waiver, discharge, or termination is sought.

          IX.10  CONTROLLING AGREEMENT.  In the event of a conflict between the
provisions of this Agreement and those of any other Loan Document, the
provisions of this Agreement shall control.


                                          63
<PAGE>

          IX.11  DISPOSITION OF COLLATERAL.  Notwithstanding any term or
provision, express or implied, in any of the Security Instruments, the
realization, liquidation, foreclosure, or any other disposition on or of any or
all of the Collateral shall be in the order and manner and determined in the
sole discretion of the Agent and the Lenders; provided, however, that in no
event shall the Agent or any Lender violate applicable law or exercise rights
and remedies other than those provided in such Security Instruments or otherwise
existing at law or in equity.

          IX.12  GOVERNING LAW.  THIS AGREEMENT AND THE NOTE SHALL BE DEEMED TO
BE CONTRACTS MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED
BY THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO PRINCIPLES THEREOF
RELATING TO CONFLICTS OF LAW; PROVIDED, HOWEVER, THAT VERNON'S TEXAS CIVIL
STATUTES, ARTICLE 5069, CHAPTER 15 (WHICH REGULATES CERTAIN REVOLVING CREDIT
LOAN ACCOUNTS AND REVOLVING TRIPARTY ACCOUNTS) SHALL NOT APPLY.

          IX.13  JURISDICTION AND VENUE.  ALL ACTIONS OR PROCEEDINGS WITH
RESPECT TO, ARISING DIRECTLY OR INDIRECTLY IN CONNECTION WITH, OUT OF, RELATED
TO, OR FROM THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE LITIGATED, AT THE
SOLE DISCRETION AND ELECTION OF THE LENDERS, IN COURTS HAVING SITUS IN HOUSTON,
HARRIS COUNTY, TEXAS.  THE BORROWER HEREBY SUBMIT TO THE JURISDICTION OF ANY
LOCAL, STATE, OR FEDERAL COURT LOCATED IN HOUSTON, HARRIS COUNTY, TEXAS, AND
HEREBY WAIVE ANY RIGHTS THEY MAY HAVE TO TRANSFER OR CHANGE THE JURISDICTION OR
VENUE OF ANY LITIGATION BROUGHT AGAINST THEM BY THE LENDERS IN ACCORDANCE WITH
THIS SECTION.

          IX.14  WAIVER OF RIGHTS TO JURY TRIAL.  THE BORROWER, THE AGENT AND
THE LENDERS HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, IRREVOCABLY, AND
UNCONDITIONALLY WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT,
PROCEEDING, COUNTERCLAIM, OR OTHER LITIGATION THAT RELATES TO OR ARISES OUT OF
ANY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE ACTS OR OMISSIONS OF THE
AGENT OR ANY LENDER IN THE ENFORCEMENT OF ANY OF THE TERMS OR PROVISIONS OF THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT OR OTHERWISE WITH RESPECT THERETO.  THE
PROVISIONS OF THIS SECTION ARE A MATERIAL INDUCEMENT FOR THE AGENT AND THE
LENDERS ENTERING INTO THIS AGREEMENT.

          IX.15  ENTIRE AGREEMENT.  THIS AGREEMENT AND THE OTHER WRITTEN LOAN
DOCUMENTS CONSTITUTE THE ENTIRE AGREEMENT BETWEEN THE PARTIES HERETO WITH

FURTHERMORE, IN THIS REGARD, THIS AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS

Compass Bank, Agent
24 Greenway Plaza, 14th Floor
Houston, Texas  77046
Attention:  Energy Lending Group

     Re:  Amended and Restated Credit Agreement dated as of April 1, 1998, by
          and among Edge Petroleum Corporation and Edge Petroleum Exploration
          Company, as Borrower, Compass Bank, as Agent and a Lender, The First
          National Bank of Chicago, as a Lender, and the additional Lenders
          party thereto from time to time (as amended, supplemented, restated or
          otherwise modified from time to time, the "CREDIT AGREEMENT")

Ladies and Gentlemen:

          We have acted as counsel to Edge Petroleum Corporation, a Delaware
corporation ("EDGE"), and Edge Petroleum Exploration Company, a Delaware
corporation ("EDGE EXPLORATION" and Edge and Edge Exploration being,
collectively, the "BORROWERS"), in connection with the transactions contemplated
in the Credit Agreement.  This Opinion is delivered pursuant to Section 3.1(__)
of the Credit Agreement, and the Agent and each Lender is hereby authorized to
rely upon this Opinion in connection with the transactions contemplated in the
Credit Agreement.  Each capitalized term used but not defined herein shall have
the meaning assigned to such term in the Credit Agreement, unless expressly
provided to the contrary herein.

          In our representation of the Borrowers, we have examined an executed
counterpart of each of the following (the "LOAN DOCUMENTS"):

          (a)  the Credit Agreement;

          (b)  the Notes;

          [Add listing of Security Instruments executed on the Closing Date]

          We have also examined the originals, or copies certified to our
satisfaction, of such other records of the Borrowers and, certificates of public
officials and officers of the Borrowers, and


                                         V-i
<PAGE>

agreements, instruments, and documents as we have deemed necessary as a basis
for the opinions hereinafter expressed.

          In making such examinations, we have, with your permission, assumed:

          (a)  the genuineness of all signatures to the Loan Documents other
     than those of the Borrowers;

          (b)  the authenticity of all documents submitted to us as originals
     and the conformity with the originals of all documents submitted to us as
     copies;

          (c)  that the Agent and the Lenders are authorized and have the power
     to enter into and perform their obligations under the Credit Agreement;

          (d)  the due authorization, execution, and delivery of all Loan
     Documents by each party thereto other than the Borrowers; and

          (e)  that the Borrowers have title to all Property covered or affected
     by the Security Instruments.

          Based upon the foregoing and subject to the qualifications set forth
herein, we are of the opinion that:

          1.   Each of the Borrowers is a corporation duly organized, legally
     existing, and in good standing under the laws of its state of
     incorporation and is duly qualified as a foreign corporation and in good
     standing in all jurisdictions wherein the ownership of its Property or the
     operation of its businesses necessitates same.

          2.   The execution and delivery by the Borrowers of the Credit
     Agreement and the borrowings thereunder, the execution and delivery by the
     Borrowers of the other Loan Documents to which either is a party, and the
     payment and performance of all Obligations and Commodity Hedge Obligations
     of the Borrowers thereunder are within the power of the Borrowers, have
     been duly authorized by all necessary corporate action, and do not (a)
     require the consent of any Governmental Authority, (b) contravene or
     conflict with any Requirement of Law, (c) to our knowledge after due
     inquiry, contravene or conflict with any indenture, instrument, or other
     agreement to which either of the Borrowers is a party or by which any
     Property of either of the Borrowers may be presently bound or encumbered,
     or (d) result in or require the creation or imposition of any Lien upon any
     Property of either of the Borrowers other than as contemplated by the Loan
     Documents.


                                         V-ii
<PAGE>

          3.   The Loan Documents to which either of the Borrowers is a party
     constitute legal, valid, and binding obligations of such Borrowers,
     enforceable against such Borrower in accordance with their respective
     terms.

          __.  To our knowledge after due inquiry, except as disclosed in
     Financial Statements of the Borrowers provided to the Agent and the Lenders
     or in Schedule 4.8 to the Credit Agreement, no litigation or other action
     of any nature affecting either of the Borrowers is pending before any
     Governmental Authority or is threatened against either of the Borrowers.
     To our knowledge after due inquiry, no unusual or unduly burdensome
     restriction, restraint, or hazard exists by contract, Requirement of Law,
     or otherwise relative to the business or operations of either of the
     Borrowers or ownership and operation of any Property of either of the
     Borrowers other than such as relate generally to Persons engaged in
     business activities similar to those conducted by the relevant Borrowers.

          __.  No authorization, consent, approval, exemption, franchise, permit
     or license of, or filing (other than filing of Security Instruments in
     appropriate filing offices) with, any Governmental Authority or any other
     Person is required to authorize or is otherwise required in connection with
     the valid execution and delivery by the Borrowers of the Loan Documents or
     any instrument contemplated thereby, or the payment and performance by the
     Borrowers of the Obligations and the Commodity Hedge Obligations.

          __.  No transaction contemplated by the Loan Documents is in violation
     of any regulations promulgated by the Board of Governors of the Federal
     Reserve System, including, without limitation, Regulations G, T, U, or X.

          __.  Neither of the Borrowers is, nor is it directly or indirectly
     controlled by or acting on behalf of any Person which is, an "investment
     company" or an "affiliated person" of an "investment company" within the
     meaning of the Investment Company Act of 1940, as amended.

          __.  Neither of the Borrowers is a "holding company," or an
     "affiliate" of a "holding company" or of a "subsidiary company" of a
     "holding company," within the meaning of the Public Utility Holding Company
     Act of 1935, as amended.

The opinions expressed herein are subject to the following qualifications and
limitations:

          A.   We are licensed to practice law only in the State of Texas [and
     other jurisdictions whose laws are not applicable to the opinions expressed
     herein]; accordingly, the foregoing opinions are limited solely to the laws
     of the State of Texas, applicable United States federal law, and the
     General Corporation Law of the State of Delaware.


                                        V-iii
<PAGE>

          B.   The validity, binding effect, and enforceability of the Loan
     Documents may be limited or affected by bankruptcy, insolvency, moratorium,
     reorganization, or other similar laws affecting rights of creditors
     generally, including, without limitation, statutes or rules of law which
     limit the effect of waivers of rights by a debtor or grantor; provided,
     however, that the limitations and other effects of such statutes or rules
     of law upon the validity and binding effect of the Loan Documents should
     not differ materially from the limitations and other effects of such
     statutes or rules of law upon the validity and binding effect of credit
     agreements, promissory notes and security instruments generally.

          C.   The enforceability of the respective obligations of the Borrowers
     under the Loan Documents is subject to general principles of equity
     (whether such enforceability is considered in a suit in equity or at law).

          This Opinion is furnished by us solely for the benefit of the Agent
and the Lenders in connection with the transactions contemplated by the Loan
Documents and is not to be quoted in whole or in part or otherwise referred to
or disclosed in any other transaction.

                              Very truly yours,

locations referred to in Section 3.3) until it shall have given to the Secured
Party not less than ten days' prior written notice of its intention to do so,

represented in Section 3.3.

      IV.7     FINANCING STATEMENT FILINGS; NOTIFICATIONS.  Debtor recognizes

Exhibit A hereto.  Debtor will immediately notify the Secured Party of any
condition or event that may change the proper location for the filing of any
financing statement or other public notice or recording for the purpose of
perfecting a security interest in the Collateral.  Without limiting the
generality of the foregoing, Debtor will (a) notify the Secured Party within a
reasonable period of time in advance of any change to a jurisdiction other than
as represented in Section 3.3 hereof, (i) in the location of Debtor's chief
place of business, (ii) in the location of the office where Debtor keeps its
records concerning the Accounts and the General Intangibles and the original of

Section, Debtor will expressly state that the notice is required by this

       V.1     DEBTOR REMAINS LIABLE UNDER ACCOUNTS.  Anything herein to the
contrary notwithstanding (including, without limitation, the grant of any rights
to the Secured Party), Debtor shall remain liable under each of the Accounts to
observe and perform all the conditions and obligations to be observed and
performed by it thereunder, all in accordance with the terms of any agreement
giving rise to each such Account.  The Secured Party shall have no obligation or
liability under any Account (or any agreement giving rise thereto) by reason of
or arising out of this Agreement or the receipt by the Secured Party of any
payment relating to such Account pursuant hereto, nor shall the Secured Party be
obligated in any manner to perform any of the obligations of Debtor under or
pursuant to any Account (or any agreement giving rise thereto), to make any
payment, to make any inquiry as to the nature or the sufficiency of any payment
received by it or as to the sufficiency of any performance by any party under
any Account (or any agreement giving rise thereto), to present or file any
claim, to take any action to enforce any performance, or to collect the payment
of any amounts which may have been assigned to it or to which it may be entitled
at any time or times.

       V.2     COLLECTIONS ON ACCOUNTS.  Prior to the occurrence of an Event of
Default, the Secured Party hereby authorizes Debtor to collect the Accounts.  At
any time following and during the continuance of any Event of Default, the
Secured Party may curtail or terminate said authority at any time and itself, or
by its agents, collect all Accounts, and any payments of Accounts collected by
Debtor shall be held by Debtor in trust for the Secured Party, segregated from
other funds of Debtor.  All Proceeds, while held by the Secured Party (or by
Debtor in trust for the Secured Party) shall continue to be Collateral securing
all of the Secured Obligations and shall not constitute payment thereof until
applied as hereinafter provided.

instruments which may be necessary or desirable to accomplish the purposes of

hereby gives the Secured Party the power and right, on behalf of Debtor, without
notice to or assent by the Debtor, to do the following:

     of Debtor to collect the Accounts has been curtailed or terminated
     pursuant hereto, or in the case of any other Collateral, at any time
     when any Event of Default shall have occurred and be continuing, in
     the name of Debtor or its own name, or otherwise, to take possession
     of and indorse and collect any checks, drafts, notes, acceptances, or
     other instruments for the payment of moneys due under, or with respect
     to, any Collateral; in the name of Debtor or otherwise to direct any
     party liable for any payment under any of the Collateral to make
     payment of any and all moneys due or to become due thereunder directly
     to the Secured Party or as the Secured Party shall direct; to ask or
     demand for, collect, receive payment of, and receipt for, any and all
     moneys, claims, and other amounts due or to become due at any time in
     respect of or arising out of any Collateral;

          (b)  at any time when an Event of Default shall have occurred and
     be continuing, to prepare, sign, and file financing statements and
     amendments thereto in the name of Debtor;

          (c)  at any time when an Event of Default shall have occurred and
     be continuing, to take or cause to be taken all actions necessary to
     perform or comply or cause performance or compliance with the terms of
     this Agreement, including, without limitation, actions to pay or
     discharge taxes and Liens levied or placed on or threatened against
     the Collateral, to effect any repairs or obtain any insurance called
     for by the terms of this Agreement, and to pay all or any part of the
     premiums therefor and the costs thereof; 

          (d)  upon the occurrence and during the continuance of any Event
     of Default, (i) to sign and indorse any invoices, freight or express
     bills, bills of lading, storage or warehouse receipts, drafts against
     debtor, assignments, verifications, notices, and other documents in
     connection with any of the

<PAGE>

     Collateral, (ii) to commence and prosecute any suits, actions, or
     proceedings at law or in equity in any court of competent jurisdiction to
     collect the Collateral or any portion thereof and to enforce any other
     right in respect of any Collateral, (iii) to defend any suit, action, or
     proceeding brought against Debtor with respect to any Collateral, (iv) to
     settle, compromise, or adjust any suit, action, or proceeding described in
     the preceding clause and, in connection therewith, to give such discharges
     or releases as the Secured Party may deem appropriate, and (v) generally,
     to sell or transfer and make any agreement with respect to or otherwise
     deal with any of the Collateral as fully and completely as though the
     Secured Party were the absolute owner thereof for all purposes, and to do,
     at the option of the Secured Party and the expense of Debtor, at any time,
     or from time to time, all acts and things which the Secured Party deems
     necessary to protect, preserve, or realize upon the Collateral and the
     Liens of the Secured Party thereon and to effect the intent of this
     Agreement, all as fully and effectively as Debtor might do; and

          (e)  at any time when an Event of Default shall have occurred and
     be continuing, to execute, in connection with any foreclosure, any
     endorsements, assignments, or other instruments of conveyance or
     transfer with respect to the Collateral.

          Debtor hereby ratifies all that said attorneys shall lawfully do or
cause to be done by virtue hereof.  This power of attorney is a power coupled
with an interest and shall be irrevocable so long as any Obligation remains
outstanding or any Commitment exists.  Debtor hereby acknowledges and agrees
that in acting pursuant to this power-of-attorney the Secured Party shall be
acting in its own interest and shall have no fiduciary duties to the Debtor, and
Debtor hereby waives any claims to the rights of a beneficiary of a fiduciary
relationship hereunder.

      VI.2     NO DUTY ON THE PART OF SECURED PARTY.  The powers conferred on
the Secured Party hereunder are solely to protect the interests of the Secured
Party in the Collateral and shall not impose any duty upon the Secured Party to
exercise any such powers.  The Secured Party shall be accountable only for
amounts that it actually receives as a result of the exercise of such powers,
and, except for its own gross negligence, neither it nor any of its officers,
directors, employees, or agents shall be responsible to the Debtor for any act
or failure to act hereunder.

                                     ARTICLE VII

                            REMEDIES; RIGHTS UPON DEFAULT

     VII.1     RIGHTS AND REMEDIES GENERALLY.  If an Event of Default shall
occur and be continuing, then and in every such case, the Secured Party shall
have all the rights of a secured party under the UCC, all rights now or
hereafter existing under all other applicable laws, and, subject to any
mandatory requirements of applicable law then in effect, all rights set forth in
this Agreement and the other Loan Documents.  No enumeration of rights in this
Section or elsewhere in this Agreement or in any other Loan Document or other
agreement shall be deemed to in any way limit the rights of the Secured Party as
described in this Section.

     VII.2     PROCEEDS.  If an Event of Default shall occur and be continuing,
in addition to the rights of the Secured Party specified with respect to the
payment of Accounts, (a) all Proceeds received by Debtor consisting of cash,
checks, and other near-cash items shall be held by Debtor in trust for the
Secured Party, segregated from other funds of Debtor, and shall forthwith upon
receipt by Debtor, be turned over to the Secured Party, in the same form
received by Debtor (appropriately indorsed or assigned by the Debtor to the
order of the Secured Party or in such other manner as shall be satisfactory to
the Secured Party), and (b) any and all such Proceeds received by the Secured
Party (whether from Debtor or otherwise), or any part thereof, shall be applied
by the Secured Party as provided in Section 7.10 hereof.

     VII.3     COLLECTION OF ACCOUNTS.  If an Event of Default shall occur and
be continuing:

          (a)  the Secured Party may instruct the obligor or obligors on
     any obligation owing or purporting to be owed to Debtor constituting
     the Collateral (including, without limitation, the Accounts) to make
     any payment required by the terms of such obligation directly to the
     Secured Party;

          (b)  the Secured Party shall have the right from time to time to
     modify (including, without limitation, to extend the time for payment
     or arrange for payment in installments) or waive rights under any such
     obligation and to compromise or settle counterclaims or setoffs with
     the obligor under any such obligation; and

          (c)  any and all of such proceeds of such collections paid to the
     Secured Party, or any part thereof, (after deduction of the Secured
     Party's expenses of collection, including, without limitation,
     reasonable attorneys' fees and disbursements), shall be applied by the
     Secured Party as provided in Section 7.10 hereof.

     VII.4     DISPOSITION OF COLLATERAL.  If an Event of Default shall occur
and be continuing:


                                          11
<PAGE>

          (a)  the Secured Party may direct Debtor to sell, assign, or
     otherwise liquidate or dispose of all or from time to time any portion
     of the Collateral, and Debtor shall do so, and the Secured Party may
     take possession of the Proceeds of such Collateral.  The Secured Party
     may direct Debtor to direct that all Proceeds of such Collateral be
     paid directly to the Secured Party or may permit the Proceeds of such
     Collateral to be paid to Debtor and all such Proceeds consisting of
     cash, checks, or near-cash items shall be held by Debtor in trust for
     the Secured Party, segregated from other funds of Debtor in a separate
     deposit account containing only Proceeds and shall forthwith upon
     receipt by Debtor, be turned over to the Secured Party, in the same
     form received by Debtor (appropriately indorsed or assigned by Debtor
     to the order of the Secured Party or in such other manner as shall be
     satisfactory to the Secured Party); and

          (b)  any and all such Proceeds received by the Secured Party
     (whether from Debtor or otherwise), shall be applied by the Secured
     Party as provided in Section 7.10 hereof.

     VII.5     DEBTOR'S ACCOUNTS.  If an Event of Default shall occur and be
continuing, the Secured Party may liquidate any securities held in any accounts
of Debtor and apply the proceeds thereof and any other amounts held in any
accounts of Debtor as provided in Section 7.10 hereof.

     VII.6     POSSESSION OF COLLATERAL.  If an Event of Default shall occur and
be continuing, (a) the Secured Party may, personally or by agents or attorneys,
immediately retake possession of the Collateral (including the originals of all
or any Accounts and Account Records) or any part thereof, from Debtor or any
other Person which then has possession of any part thereof with or without
notice or judicial process, and for that purpose may enter upon Debtor's
premises where any of the Collateral is located and remove the same and may make
reasonable use in connection with such removal of any and all services,
supplies, aids, and other facilities of Debtor, and (b) upon three days' notice
to Debtor, Debtor shall, at its own expense, assemble the Collateral, including,
without limitation, the originals of all Account Records (or from time to time
any portion thereof) and make it available to the Secured Party by delivery to
the Secured Party at any location designated by the Secured Party which is
reasonably convenient to both parties, whether at the premises of Debtor or the
Secured Party or elsewhere.  Debtor shall, at its sole expense, store and keep
any Collateral so assembled at such place or places pending further action by
the Secured Party and while the Collateral shall be so stored and kept, provide
such guards and maintenance services as shall be reasonably necessary to protect
the same and to preserve and maintain the Collateral in good condition. 
Debtor's obligation to so assemble and deliver the Collateral is of the essence
of this Agreement and, accordingly, upon application to a court of equity having
jurisdiction, the Secured Party shall be entitled to a decree requiring specific
performance by the Debtor of such obligation.


                                          12
<PAGE>

     VII.7     DISPOSITION OF THE COLLATERAL.  If an Event of Default shall
occur and be continuing, the Secured Party may sell, assign, lease, give an
option or options to purchase, or otherwise dispose of the Collateral (or
contract to do any of the foregoing) under one or more contracts or as an
entirety, and, to the extent permitted by applicable law, without the necessity
of gathering at the place of sale the property to be sold, at public or private
sale or sales, conducted by any officer, nominee or agent of, or auctioneer or
attorney for the Secured Party at any location of any third party conducting or
otherwise involved in such sale or any office of the Secured Party or elsewhere
and in general in such manner, at such time or times and upon such terms and
conditions and at such price as may be commercially reasonable, for cash or on
credit or for future delivery without assumption of any credit risk.  Any of the
Collateral may be sold, leased, assigned, or options or contracts entered to do
so, or otherwise disposed of, in the condition in which the same existed when
taken by the Secured Party or after any overhaul or repair which may be
commercially reasonable.  Any such disposition which shall be a private sale or
other private proceeding shall be made upon not less than ten days' written
notice to Debtor specifying the time after which such disposition is to be made
and the intended sale price or other consideration therefor.  Any such
disposition which shall be a public sale shall be made upon not less than ten
days' written notice to Debtor (which Debtor agrees to be commercially
reasonable) specifying the time and place of such sale and, in the absence of
applicable requirements of law to the contrary, shall be by public auction
(which may, at the option or the Secured Party, be subject to reserve), after
publication of commercially reasonable notice of such auction.  To the extent
permitted by applicable law, the Secured Party may bid for and become the
purchaser of the Collateral or any item thereof, offered for sale in accordance
with this Section without accountability to Debtor (except to the extent of
surplus money received) as provided below.  In the payment of the purchase price
of the Collateral, the purchaser shall be entitled to have credit on account of
the purchase price thereof of amounts owing to such purchaser on account of any
of the Secured Obligations and any such purchaser may deliver notes, claims for
interest, or claims for other payment with respect to such Secured Obligations
in lieu of cash up to the amount which would, upon distribution of the net
proceeds of such sale, be payable thereon.  Such notes, if the amount payable
hereunder shall be less than the amount due thereon, shall be returned to the
holder thereof after being appropriately stamped to show partial payment. 
Notwithstanding the foregoing, if the Collateral or any portion thereof is
perishable or threatens to decline speedily in value or is of a type customarily
sold in a recognized market only such notice as shall be reasonably practicable
shall be required.

     VII.8     RECOURSE.  Debtor shall remain liable for any deficiency if the
proceeds of any sale or other disposition of the Collateral are insufficient to
satisfy the Secured Obligations.  Debtor shall also be liable for all reasonable
expenses of the Secured Party incurred in connection with collecting such
deficiency, including, without limitation, the reasonable fees and disbursements
of any attorneys employed by the Secured Party to collect such deficiency.

     VII.9     EXPENSES; ATTORNEYS' FEES.  Debtor shall reimburse the Secured
Party for all its reasonable expenses in connection with the exercise of its
rights and remedies hereunder, including, without limitation, reasonable
attorneys' fees and legal expenses incurred by the Secured Party.



                                          13
<PAGE>

     VII.10    APPLICATION OF PROCEEDS.  The proceeds of any disposition of
Collateral shall be applied pursuant to Section 7.3 of the Credit Agreement.

     VII.11    LIMITATION ON DUTIES REGARDING PRESERVATION OF COLLATERAL.  The
Secured Party's sole duty with respect to the custody, safekeeping, and physical
preservation of the Collateral in its possession, under Section 9.207 of the UCC
or otherwise, shall be to deal with it in the same manner as the Secured Party
deals with similar property for its own account.  The Secured Party shall have
no obligation to take any steps to preserve rights against prior parties to any
Collateral.  Except for matters constituting gross negligence, neither the
Secured Party nor any of its directors, officers, employees, or agents shall be
liable for failure to demand, collect, or realize upon all or any part of the
Collateral or for any delay in doing so or shall be under any obligation to sell
or otherwise dispose of any Collateral upon the request of the Debtor or
otherwise.

     VII.12    WAIVER OF CLAIMS.  Except as otherwise provided in this
Agreement, Debtor hereby waives, to the extent permitted by applicable law,
notice of and judicial hearing in connection with the Secured Party's taking
possession or the Secured Party's disposition of any of the Collateral in
accordance herewith, including, without limitation, any and all prior notice and
hearing for any prejudgment remedy or remedies and any such right which the
Debtor would otherwise have under the constitution or any statute of the United
States or any state, and Debtor hereby further waives, to the extent permitted
by law:

          (a)  all damages occasioned by such taking of possession except
     any damages which are the direct result of the gross negligence of the
     Secured Party;

          (b)  all other requirements as to the time, place, and terms of
     sale or other requirements with respect to the enforcement of the
     rights of the Secured Party hereunder;

          (c)  demand of performance or other demand, notice of intent to
     demand or accelerate, notice of acceleration, presentment, protest,
     advertisement, or notice of any kind to or upon Debtor or any other
     Person, except as may be required by the Credit Agreement; and

          (d)  all rights of redemption, appraisement, valuation,
     diligence, stay, extension, or moratorium now or hereafter in force
     under any applicable law in order to stay or delay the enforcement of
     this Agreement, including the absolute sale of the Collateral or any
     portion thereof, and Debtor, for itself and all who may claim under
     it, insofar as it or they now or hereafter lawfully may, hereby waives
     the benefit of all such laws.

     VII.13    DISCONTINUANCE OF PROCEEDINGS.  In case the Secured Party shall
have instituted any proceeding to enforce any right, power, or remedy under this
Agreement by foreclosure, sale, entry, or otherwise, and such proceeding shall
have been discontinued or 



                                          14
<PAGE>

abandoned for any reason, then and in every such case, Debtor and the Secured
Party shall be returned to their former positions and rights hereunder with
respect to the Collateral subject to the security interest created under this
Agreement, and all rights, remedies, and powers of the Secured Party shall
continue as if no such proceeding had been instituted.


                                     ARTICLE VIII

                                      INDEMNITY

     VIII.1    INDEMNITY. (a) DEBTOR AGREES TO INDEMNIFY, REIMBURSE, AND HOLD
THE INDEMNITEES HARMLESS FROM ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, CLAIMS, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES, OR
DISBURSEMENTS (INCLUDING REASONABLE ATTORNEYS' FEES AND EXPENSES) (FOR THE
PURPOSES OF THIS SECTION ALL OF THE FOREGOING ARE COLLECTIVELY CALLED
"EXPENSES") OF WHATSOEVER KIND OR NATURE WHICH MAY BE IMPOSED ON, ASSERTED
AGAINST, OR INCURRED BY ANY OF SUCH INDEMNITEES IN ANY WAY RELATING TO OR
ARISING OUT OF THIS AGREEMENT OR THE DOCUMENTS EXECUTED IN CONNECTION HEREWITH
OR IN ANY OTHER WAY CONNECTED WITH THE ADMINISTRATION OF THE TRANSACTIONS
CONTEMPLATED HEREBY OR THE ENFORCEMENT OF ANY OF THE TERMS OF OR THE
PRESERVATION OF ANY RIGHTS HEREUNDER, INCLUDING, WITHOUT LIMITATION, THOSE
ARISING FROM THE NEGLIGENCE, WHETHER SOLE OR CONCURRENT, OF ANY INDEMNITEE;
PROVIDED THAT NO SUCH INDEMNITEE SHALL BE INDEMNIFIED PURSUANT TO THIS SECTION
FOR EXPENSES TO THE EXTENT ARISING FROM THE GROSS NEGLIGENCE OF SUCH INDEMNITEE.

               (b)  Debtor agrees that upon written notice by any such
Indemnitee of any assertion that could give rise to an Expense, Debtor shall
assume full responsibility for the defense thereof.  Without limiting the
application of part (a) of this Section, Debtor agrees to pay or reimburse such
Indemnitee on demand for any and all reasonable fees, costs, and expenses of
whatever kind or nature incurred in connection with the creation, preservation,
or protection of the Secured Party's Liens on, and security interests in, the
Collateral, including, without limitation, all reasonable fees and taxes in
connection with the recording or filing of instruments and documents in public
offices, payment, or discharge of any taxes or Liens or security interests upon
or in respect of the Collateral, premiums for insurance with respect to the
Collateral, all reasonable expenses incurred in the custody, preservation, use,
or operation of the Collateral when Collateral is in the Secured Party's
possession, and all other reasonable fees, costs, and expenses in connection
with protecting, maintaining, or preserving the Collateral and the Secured
Party's interest therein, whether through judicial proceedings or otherwise, or
in defending or prosecuting any actions, suits, or proceedings arising out of or
relating to the Collateral.

               (c)  Without limiting the application of parts (a) or (b) of this
Section, Debtor agrees to pay, indemnify, and hold each Indemnitee harmless from
and 


                                          15
<PAGE>

against any Expenses which such Indemnitee may suffer, expend, or incur in
consequence of or growing out of any misrepresentation by any Debtor in this
Agreement or in any statement or writing contemplated by or made or delivered
pursuant to or in connection with this Agreement.

               (d)  If and to the extent that the obligations of Debtor under
this Section are unenforceable for any reason, Debtor hereby agrees to make the
maximum contribution to the payment and satisfaction of such obligations which
is permissible under applicable law.

     VIII.2    INDEMNITY OBLIGATIONS SECURED BY COLLATERAL; SURVIVAL.  Any
amounts paid by any Indemnitee as to which such Indemnitee has the right to
reimbursement shall constitute Secured Obligations secured by the Collateral. 
The indemnity obligations of the Debtor contained in this Article VIII shall
continue in full force and effect notwithstanding the full payment and
performance of the Secured Obligations and the termination of this Agreement.


                                      ARTICLE IX

                                    MISCELLANEOUS

      IX.1     NO WAIVER; REMEDIES CUMULATIVE.  No failure or delay on the part
of the Secured Party in exercising any right, power, or privilege hereunder and
no course of dealing between any Debtor and the Secured Party shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power, or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power, or privilege.  A waiver by the Secured Party
of any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which the Secured Party would otherwise have on any
future occasion.  The rights and remedies herein expressly provided are
cumulative, may be exercised singly or concurrently and as often and in such
order as the Secured Party deems expedient, and are not exclusive of any rights
or remedies which the Secured Party would otherwise have whether by agreement or
now or hereafter existing under applicable law.  No notice to or demand on
Debtor in any case shall entitle Debtor to any other or further notice or demand
in similar or other circumstances or constitute a waiver of the rights of the
Secured Party to any other or further action in any circumstances without notice
or demand.

      IX.2     TERMINATION; RELEASE.  When the Secured Obligations have been
indefeasibly paid and performed in full and the Commitment has terminated, this
Agreement shall terminate, and the Secured Party, at the request and sole
expense of Debtor, will execute and deliver to Debtor the proper instruments
(including Uniform Commercial Code termination statements) acknowledging the
termination of this Agreement, and will duly assign, transfer, and deliver to
Debtor, without recourse, representation, or warranty of any kind whatsoever,
such of the Collateral as may be in possession of the Secured Party and has not
theretofore been disposed of, applied, or released.


                                          16
<PAGE>

      IX.3     COUNTERPARTS.  This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which when so executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument.

      IX.4     MARSHALLING.  The Secured Party shall not be under any obligation
to marshall any assets in favor of Debtor or any other Person or against or in
payment of any or all of the Secured Obligations.

      IX.5     SEVERABILITY.  In case any provision in or obligation under this
Agreement or the Secured Obligations shall be invalid, illegal, or unenforceable
in any jurisdiction, the validity, legality, and enforceability of the remaining
provisions or obligations, or of such provision or obligation in any other
jurisdiction, shall not in any way be affected or impaired thereby.

      IX.6     FINANCING STATEMENT FILING.  A photocopy or other reproduction of
this Agreement shall be sufficient as a financing statement and may be filed in
lieu of the original to the extent permitted by applicable law.  

      IX.7     NOTICES AND OTHER COMMUNICATIONS.  Except as to oral notices
expressly authorized herein, all notices, requests, and communications under
this Agreement shall be in writing (including by telecopy).  Unless otherwise
expressly provided herein, any such notice, request, or communication shall be
deemed to have been duly given or made when provided in accordance with the
terms of the Credit Agreement.

      IX.8     PARTIES IN INTEREST.  This Agreement shall be binding upon and
inure to the benefit of Debtor, the Secured Party, and their respective legal
representatives, successors, and assigns.  No other Person shall have any right,
benefit, priority, or interest hereunder or as a result hereof or have standing
to require satisfaction of provisions hereof in accordance with their terms, and
any or all of such provisions may be freely waived in whole or in part by the
Secured Party at any time if the Secured Party in its sole discretion deems it
advisable to do so.

      IX.9     AMENDMENTS.  Neither this Agreement nor any provision hereof may
be amended, supplemented, modified, discharged, or terminated orally, but only
by an instrument in writing signed by the party against whom enforcement of the
amendment, supplement, modification, discharge, or termination is sought.

     IX.10     ENTIRE AGREEMENT.  THIS AGREEMENT CONSTITUTES THE ENTIRE
AGREEMENT BETWEEN THE PARTIES HERETO WITH RESPECT TO THE SUBJECT HEREOF AND
SHALL SUPERSEDE ANY PRIOR AGREEMENTS, WHETHER WRITTEN OR ORAL, BETWEEN THE
PARTIES HERETO RELATING TO THE SUBJECT HEREOF.  FURTHERMORE, IN THIS REGARD,
THIS AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS REPRESENT, COLLECTIVELY, THE
FINAL AGREEMENT AMONG THE PARTIES THERETO 


                                          17
<PAGE>

AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT
ORAL AGREEMENTS OF SUCH PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG
SUCH PARTIES.

     IX.11     GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS (WITHOUT GIVING EFFECT TO
PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAWS).

     IX.12     JURISDICTION AND VENUE.  ALL ACTIONS OR PROCEEDINGS WITH RESPECT
TO, ARISING DIRECTLY OR INDIRECTLY IN CONNECTION WITH, OUT OF, RELATED TO OR
FROM THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT TO WHICH ANY DEBTOR IS A PARTY
MAY BE LITIGATED, AT THE SOLE DISCRETION AND ELECTION OF THE SECURED PARTY, IN
COURTS HAVING SITUS IN HOUSTON, HARRIS COUNTY, TEXAS.  DEBTOR HEREBY SUBMITS TO
THE JURISDICTION OF ANY LOCAL, STATE, OR FEDERAL COURT LOCATED IN HOUSTON,
HARRIS COUNTY, TEXAS, AND HEREBY WAIVES ANY RIGHTS IT MAY HAVE TO TRANSFER OR
CHANGE THE JURISDICTION OR VENUE OF ANY LITIGATION BROUGHT AGAINST IT BY THE
SECURED PARTY IN ACCORDANCE WITH THIS SECTION.

          IN WITNESS WHEREOF, this Agreement is executed as of the date first
above written.

                                  SECURITY INTEREST

                1.9      GRANT OF SECURITY INTEREST IN COLLATERAL.  The 
Pledgor, for value received, the receipt and sufficiency of which are hereby 
acknowledged, and to induce the Lender to extend credit to or for the benefit 
of the Pledgor, hereby pledges to the Agent for the benefit of the Lenders, 
and its successors and assigns, and hereby grants to the Agent for the 
benefit of the Lenders, and its successors and assigns, a first lien on and a 
security interest in the stock described on Schedule I ("Collateral") to 
secure the Obligations.

                1.10     DELIVERY OF COLLATERAL.  All certificates or
instruments representing or evidencing the Securities shall be delivered to and
held by the Agent for the benefit of the Lenders for the sole purpose of
possession of the Collateral or any portion thereof pursuant to this Security
Agreement, and shall be in suitable form for transfer by delivery, or shall be
accompanied by duly executed instruments of transfer or assignment in blank, all
in form and substance satisfactory to the Agent.  The Agent shall at all times
have actual possession of the Securities and shall be deemed to have possession
of any of the Collateral in transit to it or set apart for it.

                1.11     POWER OF ATTORNEY.  The Pledgor hereby irrevocably
constitutes and appoints the Lender and any authorized officer or agent thereof,
with full power of substitution, as its true and lawful attorney-in-fact with
full irrevocable power and authority in the place and stead of the Pledgor and
in the name of the Pledgor or in its own name, from time to time in the
discretion of the Agent, for the purpose of carrying out the terms of this
Security Agreement, and without notice to the Pledgor, to take any and all
appropriate action and to execute any and all documents and instruments which
may be necessary or desirable to accomplish the purposes of this Security
Agreement, including, without limitation, the following:

          (1)   to transfer to or register any or all of the Collateral in the
                name of the Lender or any of its nominees;

          (2)   to exchange the certificates or instruments representing or
                evidencing the Collateral for certificates or instruments of
                smaller or larger denominations;

          (3)   upon the occurrence and during the continuance of any Event of
                Default, (i) to receive payment of and receipt for any and all
                moneys, claims and other amounts due and to become due at any
                time in respect of or arising out of any Collateral, (ii) to
                commence and prosecute any suits, actions or proceedings at law
                or in equity in any court of competent jurisdiction to collect
                the Collateral or any part thereof and to enforce any other
                right in respect of any Collateral, (iii) to defend any suit,
                action or proceeding brought against the Pledgor with respect
                to any Collateral, (iv) to settle, compromise or adjust any
                suit, action or proceeding described above and, in connection
                therewith, to give such discharges or releases as the Agent may
                deem appropriate, and (v) to


                                          3
<PAGE>

                complete any blanks contained in any instruments of transfer or
                assignment appended to or delivered with the certificates
                representing the Securities; and

          (4)   to exchange any of the Collateral for other Property upon
                reorganization, recapitalization or other readjustment of any
                of the issuers of the Securities and in connection therewith to
                deposit any of the Collateral with any committee or depository
                upon such terms as the Lender may determine; and, subsequent to
                any Event of Default, to exercise, at the option of the Agent,
                voting rights as to any of the Collateral;

all without notice and without liability except to account for Property actually
received by the Lender.

          The Pledgor hereby ratifies all that said attorney shall lawfully do
or cause to be done within the scope of the power of attorney granted hereunder.
This power of attorney is a power coupled with an interest and shall be
irrevocable so long as any Obligation remains outstanding or any Commitment
exists.  The powers conferred on the Lender hereunder are solely to protect the
interests of the Lender in the Collateral and shall not impose any duty upon it
to exercise any such powers.  The Lender shall be accountable only for amounts
that it actually receives as a result of the exercise of such powers, and
neither it nor any of its officers, directors, employees, or agents shall be
responsible to the Pledgor for any act or failure to act, except for gross
negligence.


                                      ARTICLE 3.

                            REPRESENTATIONS AND WARRANTIES

          To induce the Lender to enter into the Credit Agreement and to make
Loans to or for the benefit of the Pledgor, the Pledgor represents and warrants
to the Agent and the Lenders (which representations and warranties shall survive
the delivery of this Security Agreement and the other Loan Documents) that:

                1.12     STATUS OF COLLATERAL.  All signatures on the
certificates evidencing the Securities are genuine or authorized; the transfer
of the Securities by the Pledgor to the Agent for the benefit of the Lenders are
effective; and the Pledgor knows of no fact that might impair the validity of
the Securities.  The Securities (a) have been duly authorized, validly issued,
drawn, made, and/or accepted, (b) are genuine, validly outstanding, fully paid,
and nonassessable, (c) were not issued in violation of the preemptive rights of
any Person or any agreement by which the Pledgor or any issuer of such
Collateral is bound, and (d) have not been materially altered.

                1.13     NO MATERIAL MISSTATEMENTS.  No information, exhibit, or
report furnished by the Pledgor to the Agent in connection with the negotiation
of this Security Agreement contained or contains any material misstatement of
fact or omitted to state a material fact or any fact necessary to make the
statements contained therein, in light of the circumstances in which they were
made, not misleading.

<PAGE>

                1.14     OWNERSHIP AND LIENS.  Except for the security interest
in favor of the Agent for the benefit of the Lenders, the Pledgor owns (and at
the time of transfer or delivery of the Collateral to the Agent for the benefit
of the Lenders owned or will own) good and indefeasible title to the Collateral
free and clear of any other security interests, liens, adverse claims, or
options; the Pledgor has (and at the time of transfer or delivery of the
Collateral to the Agent for the benefit of the Lenders had or will have) full
right, power, and authority to convey, assign, transfer, and deliver the
Collateral to the Agent for the benefit of the Lenders and to grant a security
interest in the Collateral to the Lender in the manner provided herein.


                                      ARTICLE 4.

                               COVENANTS AND AGREEMENTS

          Unless agreed in writing by the Agent to the contrary, the Pledgor
agrees, so long as any Obligation remains outstanding or unpaid or any
Commitment exists:

                1.15     PAYMENT OF ASSESSMENTS AND CHARGES.  To pay all taxes,
charges, liens and assessments against the Collateral; and upon the failure of
the Pledgor to do so, the Agent at its option may, but will not be obligated to,
pay any of them.

                1.16     DELIVERY OF COLLATERAL.  That any and all (a) dividends
paid or payable other than in cash and all instruments and other property
received, receivable or otherwise distributed in respect of or in exchange for
any Collateral, (b) dividends and other distributions paid or payable in cash in
respect of any Collateral in connection with a partial or total liquidation or
dissolution or in connection with a reduction of capital, capital surplus or
paid-in surplus, and (c) cash paid, payable or otherwise distributed in respect
of principal of, in redemption of or in exchange for any Collateral, shall be
forthwith delivered to the Agent to hold as Collateral for the benefit of the
Agent and shall, if received by the Pledgor, be received in trust for the
benefit of the Lender, be segregated from the other property or funds of the
Pledgor, and be forthwith delivered to the Lender as Collateral in the same form
as so received (with any necessary endorsement).

                1.17     FURTHER ASSURANCES.  To promptly cure any defects in
the execution and delivery of this Security Agreement and execute, acknowledge,
and deliver such other assurances and instruments and take such other action as
shall, in the opinion of the Agent, be necessary to fulfill the terms of this
Security Agreement and to confirm, perfect, and preserve the security interest
created and intended to be created hereby and to vest more completely in and
assure to the Lender its rights under this Security Agreement.

                1.18     PROHIBITED LIENS AND FILINGS.  That it will not pledge,
mortgage, or otherwise encumber, create, or suffer a security interest to exist
in any of the Collateral (other than in favor of the Agent) or sell, assign, or
otherwise transfer any of the Collateral to anyone other than the Lender or file
or permit to be filed any financing statement or other security instrument with
respect to the Collateral other than in favor of the Agent.

                                      ARTICLE 5.

                                 RIGHTS AND REMEDIES

                1.19     REMEDIES UPON DEFAULT.    Upon the occurrence and
during the continuance of an Event of Default, the Agent may, at its option,
declare all Obligations immediately due and payable, without presentment,
demand, protest, notice of protest, default or dishonor, notice of intent to
accelerate maturity, notice of acceleration of maturity or other notice of any
kind, all of which are hereby expressly waived by the Pledgor, and may exercise
any and all other remedies provided by law or pursuant to the Loan Documents.

          (1)   If all or any part of the Obligations shall become due and
                payable, the Lender may then, or at any time thereafter, apply,
                set-off, collect, sell in one or more sales, or otherwise
                dispose of, any or all of the Collateral, in its then condition
                or following any commercially reasonable preparation or
                processing, in such order as the Agent may elect.  Any such
                sale may be made either at public or private sale at the place
                of business of the Agent, any brokers' board or securities
                exchange or elsewhere, either for cash or upon credit or for
                future delivery, at such price as the Lender may deem fair.
                The Agent may be the purchaser of any or all Collateral so sold
                and may hold the same thereafter in its own right free from any
                claim of the Pledgor or right of redemption.  No such purchase
                or holding by the Lender shall be deemed a retention by the
                Agent in satisfaction of the Obligations.  All demands,
                notices, and advertisements, and the presentment of property at
                sale are hereby waived.  If, notwithstanding the foregoing
                provisions, any applicable provision of the Uniform Commercial
                Code or other law requires the Lender to give reasonable notice
                of any such sale or disposition or other action, ten days'
                prior written notice shall constitute reasonable notice.  The
                Agent may require the Pledgor to assemble the Collateral and
                make it available to the Agent at a place designated by the
                Lender that is reasonably convenient to the Agent and the
                Pledgor.  Any sale hereunder may be conducted by an auctioneer
                or any officer or agent of the Agent.

          (2)   In connection with the sale of Collateral which is stock or
                other investment securities, the Agent must limit prospective
                purchasers to the extent deemed necessary or advisable by the
                Lender to render such sale exempt from the registration
                requirements of the Securities Act of 1933, as amended (the
                "ACT"), and any applicable state securities laws.  No sale so
                made in good faith by the Lender shall be deemed not to be
                "commercially reasonable" because so made; provided, however,
                that nothing in this Security Agreement shall be deemed to
                impose any obligation whatsoever to file a registration
                statement under the Act or any state securities law with
                respect to any sale of Collateral by the Agent.

                1.20     VOTING RIGHTS, DIVIDENDS, ETC. PRIOR TO DEFAULT.   So
long as no Event of Default shall have occurred and be continuing:


                                          6
<PAGE>

          (1)   the Pledgor will be entitled to exercise any and all voting and
                other consensual rights pertaining to the Collateral or any
                part thereof for any purpose not inconsistent with the terms of
                this Security Agreement;

          (2)   subject to the further provisions of this Security Agreement,
                the Pledgor shall be entitled to receive and retain any and all
                dividends paid in respect of the Collateral; provided, however,
                that any and all

                (1)   dividends paid or payable other than in cash and all
                    instruments and other Property received, receivable, or
                    otherwise distributed in respect of or in exchange for
                    any Collateral,

                (2)   dividends and other distributions paid or payable in
                    cash in respect of any Collateral in connection with a
                    partial or total liquidation or dissolution or in
                    connection with a reduction of capital, capital surplus
                    or paid-in surplus, and

                (3)   cash paid, payable or otherwise distributed in
                    respect of principal of, in redemption of or in
                    exchange for any Collateral,

shall be forthwith delivered to the Agent to hold as Collateral and shall, if
received by the Pledgor, be received in trust for the benefit of the Agent, be
segregated from the other property or funds of the Pledgor, and be forthwith
delivered to the Agent as Collateral in the same form as so received (with any
necessary endorsement); and

          (3)   the Agent shall execute and deliver (or cause to be executed
                and delivered) to the Pledgor all such proxies and other
                instruments as the Pledgor may reasonably request for the
                purpose of enabling the Pledgor to exercise the voting and
                other rights which it is entitled to exercise pursuant to
                Section 5.2(a) above and to receive the dividends which it is
                authorized to receive and retain.

                1.21     VOTING RIGHTS, DIVIDENDS, ETC. AFTER DEFAULT.  Upon the
occurrence and during the continuance of an Event of Default:

          (1)   at the option of the Agent with notice to the Pledgor, all
                rights of the Pledgor to exercise the voting and other
                consensual rights which it would otherwise be entitled to
                exercise pursuant to Section 5.2(a) above and to receive the
                dividends which it would otherwise be authorized to receive and
                retain pursuant to Section 5.2(b) above shall cease and shall
                thereupon become vested in the Agent, who shall thereupon have
                the sole right to exercise such voting and other consensual
                rights and to receive and hold as Collateral such dividends;
                and

          (2)   all dividends which are received by the Pledgor contrary to the
                provisions of Section 5.3(a) above shall be received in trust
                for the benefit of the Lender,


                                          7
<PAGE>

                shall be segregated from other funds of the Pledgor and shall
                be forthwith paid over to the Agent as Collateral in the same
                form as so received (with any necessary endorsement).

                1.22     PROCEEDS.  Prior to all or any part of the Obligations
becoming due and payable as specified in Section 7.3 of the Credit Agreement,
all cash sums or other property received by the Agent on account of the
Collateral shall be held as Collateral.  After all or any part of the
Obligations shall become due and payable as specified in Section 7.3 of the
Credit Agreement, the proceeds of any sale or other disposition of the
Collateral and all sums received or collected by the Agent from or on account of
the Collateral shall be applied by the Lender in the manner set forth in Section
9.504 of the UCC.

                1.23     AGENT DUTIES.  The Agent shall be under no duty
whatsoever to make or give any presentment, demand for performance, notice of
nonperformance, protest, notice of protest, notice of dishonor, or other notice
or demand in connection with any Collateral or the Obligations, or to take any
steps necessary to preserve any rights against prior parties.  The Agent shall
not be liable for failure to collect or realize upon any or all of the
Obligations or Collateral, or for any delay in so doing, nor shall the Agent be
under any duty to take any action whatsoever with regard thereto.  The Agent
shall use reasonable care in the custody and preservation of any Collateral in
its possession.  The Agent shall have no duty to comply with any recording,
filing, or other legal requirements necessary to establish or maintain the
validity, priority, or enforceability of, or the rights of the Agent in or to,
any of the Collateral.

                1.24     THE AGENT'S ACTIONS.  The Pledgor waives any right to
require the Agent to proceed against any Person, exhaust any collateral or
pursue any other remedy in the power of the Lender; waives any and all notice of
acceptance of this Security Agreement or of creation, modification, renewal, or
extension for any period of any Obligations; and waives any defense arising by
reason of any disability or other defense of any guarantor or other Person
primarily or secondarily liable with respect to all or any portion of the
Obligations ("OTHER LIABLE PARTY"), or by reason of the cessation from any cause
whatsoever of the liability of any Other Liable Party.  All dealings between the
Pledgor and the Agent shall conclusively be presumed to have been had or
consummated in reliance upon this Security Agreement.  Until all Obligations
shall have been paid and/or performed in full and the Commitment shall have
terminated, the Pledgor (a) shall have no right to subrogation, (b) waives any
right to enforce any remedy that the Lender now has or may hereafter have
against any Other Liable Party, and (c) except as otherwise expressly provided
in this Security Agreement, waives any benefit of and right to participate in
any collateral or security whatsoever now or hereafter held by the Agent.

                                      ARTICLE 6.

                                    MISCELLANEOUS

                1.25     TRANSFER OF OBLIGATIONS AND COLLATERAL.  Subject to the
terms of the Credit Agreement, the Pledgor hereby agrees that the Agent and/or
Lenders may transfer any or all of the Obligations.  Upon any such transfer, the
Agent and/or Lenders may transfer their rights in the Collateral and shall be
fully discharged thereafter from all liability with respect to the Collateral so
transferred, and the transferee shall be vested with all rights, powers, and
remedies of the Agent and/or Lenders hereunder with respect to Collateral so
transferred.  With respect to any Collateral not so transferred, the Lender
shall retain all rights, powers, and remedies hereby given.  The Agent and/or
Lenders may at any time deliver any or all of the Collateral to the Pledgor,
whose receipt shall be a complete and full acquittance for the Collateral so
delivered, and the Agent and/or Lenders shall thereafter be discharged from any
liability therefor.

                1.26     CUMULATIVE SECURITY.  The execution and delivery of
this Security Agreement in no manner shall impair or affect any other security
(by endorsement or otherwise) for the payment of the Obligations.  No security
taken hereafter as security for payment of all or any portion of the Obligations
shall impair in any manner or affect this Security Agreement.  All such present
and future additional security is to be considered as cumulative security.

                1.27     CONTINUING AGREEMENT.  This is a continuing agreement
and the conveyance hereunder shall remain in full force and effect and all the
rights, powers, and remedies of the Agent and/or Lenders hereunder shall
continue to exist until the Obligations shall be paid in full as the same become
due and payable, the Commitment has terminated, and the Agent, upon request of
the Pledgor, has executed a written termination statement, reassigned to the
Pledgor, without recourse, the Collateral and all rights and liens conveyed
hereby and returned possession of the Collateral to the Pledgor.  Furthermore,
it is contemplated by the parties hereto that there may be times when no
Obligations shall be owing.  Notwithstanding such occurrences, this Security
Agreement shall remain valid and shall be in full force and effect as to
subsequent Obligations provided that the Agent has not executed a written
termination statement and returned possession of the Collateral to the Pledgor.
Otherwise, this Security Agreement shall continue irrespective of the fact that
the liability of the Pledgor or any Other Liable Party may have ceased and
notwithstanding the death or incapacity of the Pledgor or any Other Liable Party
or any other event or proceeding affecting the Pledgor and/or any Other Liable
Party.

                1.28     CUMULATIVE RIGHTS.  The rights, powers, and remedies of
the Agent and the Lenders hereunder shall be in addition to all rights, powers,
and remedies given by statute or rule of law and are cumulative.  The exercise
of any one or more of the rights, powers, and remedies provided herein shall not
be construed as a waiver of any other rights, powers, and remedies.  The Agent
and the Lenders shall have the rights, powers, and remedies of a secured party
under the Texas Business and Commerce Code, as amended.

                1.29     EXERCISE OF RIGHTS.  Time shall be of the essence for
the performance of any act under this Security Agreement by the Pledgor, but
neither the Agent or the Lenders' acceptance of partial or delinquent payments
nor any forbearance, failure, or delay by the Agent


                                          9
<PAGE>

or the Lenders in exercising any right, power or remedy shall be deemed a waiver
of any obligation of the Pledgor or any Other Liable Party or of any right,
power, or remedy of the Agent or the Lenders or preclude any other or further
exercise thereof; and no single or partial exercise of any right, power, or
remedy shall preclude any other or further exercise thereof or the exercise of
any other right, power, or remedy.

                1.30     REMEDY AND WAIVER.  The Agent may remedy or waive any
default hereunder without waiving the default remedied or waiving any prior or
subsequent default.

                1.31     NON-JUDICIAL REMEDIES.  The Agent and the Lenders may
enforce their rights hereunder without prior judicial process or judicial
hearing.  The Pledgor expressly waives, renounces, and knowingly relinquishes
any and all legal rights which might otherwise require the Agent and the Lenders
to enforce their rights by judicial process.  In so providing for non-judicial
remedies, the Pledgor recognizes and concedes that such remedies are consistent
with the usage of the trade, are responsive to commercial necessity and are the
result of bargain at arm's length.  Nothing herein is intended to prevent the
Lender or the Pledgor from resorting to judicial process at such party's option.

                1.32     PRESERVATION OF LIABILITY.  Neither this Security
Agreement nor the exercise by the Agent or the Lenders of (or the failure to so
exercise) any right, power, or remedy conferred herein or by law shall be
construed as relieving the Pledgor or any Other Liable Party from full liability
thereon and for any deficiency thereon.

                1.33     NOTICES AND OTHER COMMUNICATIONS.  Except as to verbal
notices expressly authorized herein, which verbal notices shall be confirmed in
writing, all notices, requests, and communications hereunder shall be in writing
(including by telecopy).  Unless otherwise expressly provided herein, any such
notice, request, demand, or other communication shall be deemed to have been
duly given or made when delivered by hand, or, in the case of delivery by mail,
when deposited in the mail, certified mail, return receipt requested, postage
prepaid, or, in the case of telecopy notice, when receipt thereof is
acknowledged orally or by written confirmation report, addressed as follows:

be sent.

                1.34     PARTIES IN INTEREST.  All covenants and agreements
herein contained by or on behalf of the Pledgor or the Agent and the Lenders
shall be binding upon and inure to the benefit of the Pledgor or the Agent and
the Lenders, as the case may be, and their respective legal representatives,
successors, and assigns.

                1.35     AMENDMENT AND WAIVER.  This Security Agreement may not
be amended nor may any of its terms be waived except in writing duly signed by
the party against whom enforcement of the amendment or waiver is sought.

                1.36     INVALIDITY.  If any provision of this Security
Agreement is rendered or declared illegal, invalid, or unenforceable by reason
of any existing or subsequently enacted legislation or by a judicial decision
that has become final, the Pledgor and the Agent shall promptly meet and
negotiate substitute provisions for those rendered illegal, invalid, or
unenforceable, but all of the remaining provisions shall remain in full force
and effect.

                1.37     GOVERNING LAW.  THIS SECURITY AGREEMENT SHALL BE DEEMED
TO BE A CONTRACT MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO PRINCIPLES
THEREOF RELATING TO CONFLICTS OF LAW, PROVIDED, HOWEVER, THAT VERNON'S TEXAS
CIVIL STATUTES, ARTICLE 5069, CHAPTER 15 (WHICH REGULATES CERTAIN REVOLVING
CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY.

                1.38     JURISDICTION AND VENUE.  ALL ACTIONS OR PROCEEDINGS
WITH RESPECT TO, ARISING DIRECTLY OR INDIRECTLY IN CONNECTION WITH, OUT OF,
RELATED TO, OR FROM THIS SECURITY AGREEMENT OR ANY OTHER LOAN DOCUMENT TO WHICH
THE PLEDGOR IS A PARTY MAY BE LITIGATED, AT THE SOLE DISCRETION AND ELECTION OF
THE AGENT, IN COURTS HAVING SITUS IN HOUSTON, HARRIS COUNTY, TEXAS.  THE PLEDGOR
HEREBY SUBMITS TO THE JURISDICTION OF ANY LOCAL, STATE, OR FEDERAL COURT LOCATED
IN HOUSTON, HARRIS COUNTY, TEXAS, AND HEREBY WAIVES ANY RIGHTS IT MAY HAVE TO
TRANSFER OR CHANGE THE JURISDICTION OR VENUE OF ANY LITIGATION BROUGHT AGAINST
IT BY THE LENDER IN ACCORDANCE WITH THIS SECTION.

                1.39     WAIVER OF RIGHTS TO JURY TRIAL.  THE PLEDGOR AND THE
AGENT HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, IRREVOCABLY, AND
UNCONDITIONALLY WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT,
PROCEEDING, COUNTERCLAIM, OR OTHER LITIGATION THAT RELATES TO OR ARISES OUT OF
ANY OF THIS SECURITY AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE ACTS OR
OMISSIONS OF THE AGENT IN THE ENFORCEMENT OF ANY OF THE TERMS OR PROVISIONS OF
THIS SECURITY AGREEMENT OR ANY OTHER LOAN DOCUMENT OR OTHERWISE WITH RESPECT
THERETO.  THE PROVISIONS OF THIS SECTION ARE A MATERIAL INDUCEMENT FOR THE
LENDER ENTERING INTO THE CREDIT AGREEMENT.

                1.40     ENTIRE AGREEMENT.  THIS SECURITY AGREEMENT CONSTITUTES
THE ENTIRE AGREEMENT BETWEEN THE PARTIES HERETO WITH RESPECT TO THE SUBJECT
HEREOF AND SHALL SUPERSEDE ANY PRIOR AGREEMENTS, WHETHER WRITTEN OR ORAL,
BETWEEN THE PARTIES HERETO RELATING TO THE SUBJECT HEREOF.  FURTHERMORE, IN THIS
REGARD, THIS SECURITY AGREEMENT AND THE OTHER WRITTEN LOAN DOCUMENTS REPRESENT,
COLLECTIVELY, THE FINAL AGREEMENT AMONG THE PARTIES THERETO AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF SUCH PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG SUCH
