                           AMERAC ENERGY CORPORATION

             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                  (UNAUDITED)

  1. ORGANIZATION AND NATURE OF BUSINESS
 
     Amerac Energy Corporation, ("Amerac" or the "Company") was formed in 1969
  and is headquartered in Houston, Texas.  The Company is engaged in the
  acquisition, development and enhancement of oil and gas properties in the
  United States.
 
  2. SUMMARY OF SIGNIFICATION ACCOUNTING POLICIES
 
     The results of operations for the interim periods shown in this report are
  not necessarily indicative of results to be expected for the year.  In the
  opinion of management, the accompanying unaudited financial statements
  contain all adjustments necessary to present fairly the financial position as
  of September 30, 1996, and the results of operations for the three months and
  nine months ended September 30, 1995 and 1996, and cash flow for the nine
  months ended September 30, 1995 and 1996.  These financial statements and the
  notes thereto should be read in conjunction with the Company's annual report
  on Form 10-K for the year ended December 31, 1995.
 
     Net income (loss) per share is computed by dividing the net income or loss
  attributable to common shareholders by the weighted average number of shares
  of Common Stock outstanding. In determining the net income (loss) attributable
  per share for the periods shown other than for the three months ended
  September 30, 1996, the Company decreased income by the preferred stock
  dividend and accretion of discount. The stock options are not material or are
  anti-dilutive and are not included in the average shares outstanding during
  the periods presented.
  
     From 1991 until 1996, the Company has accounted for its investment in
  Petroleum Financial Inc. ("PFI") on the cost method of accounting.  PFI
  performs certain financial, accounting, tax, administrative, land, computer
  operations and shareholder relations activities for Amerac. In July 1995, the
  Company's interest in PFI increased from 15% to 26%; thus, commencing in
  1996, the Company began accounting for its investment in PFI on the equity
  method of accounting.
 
  3. INDEBTEDNESS
 
     On August 15, 1996, the Company amended its revolving line of credit
  agreement with Bank One, Texas National Association ("Bank Credit
  Agreement").  The amendment, among other things, increases the Company's line
  of credit from $15 to $30 million and extended the due date to May 31, 1998.
  In addition, the Company also executed a $1 million bridge loan agreement
  ("Bridge Loan") a portion of which the Company has used to fund acquisitions
  and development expenditures.  The Bridge Loan must be repaid on the earlier
  of the date of receipt of any funds from any equity offerings or February 16,
  1997 and bears interest at the Bank One Texas Base Rate plus two and one-half
  percent which is currently 10.75%.  Both of these agreements are secured by
  all of the Company's oil and gas properties, and contain various covenants
  which may, if not met, cause the Company to be in default or reduce its
  access to additional borrowings.  At November 1, 1996, there was $849,000
  outstanding under the bridge loan facility and $11.7 million was outstanding
  under the Bank Credit Agreement.  The Company's borrowing base was $11.7
  million at November 1, 1996 with a mandatory reduction of $250,000 each
  month.  The Bank Credit Agreement bears interest at the Bank One Texas Base
  Rate plus three quarter percent (9%) at September 30, 1996.

  4. SHAREHOLDER'S EQUITY
 
     COMMON STOCK
 
     The Company has called a Special Meeting of Stockholders for November 20,
  1996, for the purpose of approving an amendment to the Company's Certificate
  of Incorporation (the "Amendment").  The Amendment would provide for a one-
  for-fifteen reverse split of Common Stock.  If this Amendment is approved,
  the outstanding stock will be reduced from 42,530,252 at November 1, 1996 to
  2,835,350.

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS --(CONTINUED)

                                  (UNAUDITED)

                                        
   At the Company's annual meeting of Shareholders on July 11, 1996, the
Shareholders approved an amendment to convert each share of $4.00 Senior
Preferred Stock (the "Senior Preferred") outstanding to nine (9) shares of
Common Stock thus eliminating the Senior Preferred Stock.  The Shareholders also
approved an amendment to the Certificate of Incorporation that increased the
authorized Common Stock to 100 million shares.  In June 1996, the Company
completed a private sale of approximately 1.08 million restricted shares of
Common Stock at an average price of $.34 per share.

   Supplemental Pro Forma Earning (Loss) Per Share would have been $.00 for the
three months ended September 30, 1995 and $(.01) for the nine months ended
September 30, 1995, if the Senior Preferred Stock conversion occurred on January
1, 1995. The Supplemental Pro Forma Earning Per Share would have been unchanged
at $.01 for the three months ended September 30, 1996 and $.05 for the nine
months ended September 30, 1996.

   As a result of the conversion of the Senior Preferred Stock the utilization
of the Net Operating Tax Loss Carryforward of approximately $200 million will be
limited to an annual utilization of approximately $300,000 per year.  The
Company's statutory depletion carryforwards will not be limited as a result of
the Senior Preferred Stock Conversion.

5. ACQUISITION ACTIVITIES
 
   Effective January 1, 1996, the Company acquired the Common Stock of Fremont
Energy Corporation ("Fremont"), an Oklahoma-based oil and gas company, for $7
million paid in cash and 3.3 million shares of Common Stock of the Company.
Fremont has 131 wells located predominately in central Oklahoma and Kansas
concentrated in three major fields. Fremont's estimated net proved reserves at
December 31, 1995, totaled approximately 13.4 billion cubic feet equivalent
("BCFE").
 
   The Company acquired on August 16, 1996 a majority interest in sixteen gas
wells in the Texan Gardens Field, located in Hidalgo County, Texas. The field,
situated in the heart of the Vicksburg Trend of the Texas Gulf Coast region,
produces gas from multiple sands between depths of 7,700 feet to 9,400 feet. The
Company's average working interest in these properties approximates 58%, with a
net revenue interest averaging 40%. Based on a March 1, 1996 effective date, the
Company estimated that proved reserves associated with this $1.8 million
acquisition totaled 4.4 BCFE, of which seventy percent are behind pipe.
 
   The Company acquired on August 19, 1996 a majority non-operated interest in
22 producing wells from numerous working interest owners on the McLemore-
Drummonds Ranch and the Sloan X's Ranch in Shackelford, Stephens, Throckmorton,
and Haskell Counties of Central Texas (The "Throckmorton" acquisition).
Production in this acreage is predominantly from the Mississippian at
approximately 4,800 feet and the Caddo at approximately 2,800 feet. Amerac's
working interest in the McLemore-Drummonds Ranch and the Sloan X's Ranch
approximates 76% and 82%, respectively. The net revenue interests in the two
ranches are 57% and 65%, respectively. Based on a June 1, 1996 effective date,
the company estimated that proved reserves associated with the $1.1 million
acquisitions totaled 224,700 barrels of oil equivalent ("BOE"), of which one
hundred percent are producing.

   The Company also acquired in August 1996, a producing lease on the east flank
of the Cosden Field for approximately $190,000. Based on a July 1, 1996
effective date, the Company estimated the proved reserves associated with this
acquisition totaled 679 MMCFE. In addition to the production associated with a
deep well on this new lease, the leasehold interests that come with the
acquisition include rights to a behind pipe zone in a currently inactive well
already owned by the Company. The Company intends to recomplete this inactive
well in the behind pipe zone.

   These acquisitions are accounted for under purchase accounting and results of
operations will be consolidated from the date of the respective consummation.

   The pro forma impact of the Fremont acquisition, the Texan Gardens Field
acquisition, the 1995 Cosden acquisition, and the December 1995 sale of N.W.
Arapahoe, assuming the transactions had occurred at January 1, 1995, would have
been as follows for the nine months ended September 30, 1996 and September 30,
1995. The 1996 Throckmorton acquisition and the 1996 Cosden acquisition would
not have a material impact on the Pro Forma Statement of Operations, and, thus
have not been included.

6. CONTINGENCIES

   The Company's Shurly Ranch Properties were the subject of litigation related
to the proper settlement of a take-or-pay payment received by the Company from
El Paso Natural Gas Company ("El Paso"). The Company is obligated under a
settlement agreement dated January 8, 1994, to allow El Paso to recover the
prepayment by delivering 65% of the monthly gas production volumes at an imputed
price of $3.25 per MMBTU through February 1997. Beginning in March 1997, the
Company has the option of (1) continuing to deliver gas until it is unable to
meet the minimum delivery requirement or (2) paying the remaining unrecovered
balance, not to exceed $360,000. Due to the uncertainty of El Paso's gas
requirements, the Company has reviewed, in conjunction with the annual year end
reserve analysis prepared by an independent petroleum engineering firm, the
current economic reserve life and production capabilities of the properties to
determine their ability to deliver the volumes necessary to satisfy the
remaining prepayment. The Company believes that its current contract obligation
of $534,000 is sufficient to cover any remaining obligation under the settlement
agreement at September 30, 1996. The Company has classified the maximum
unrecovered balance of $360,000 as a current obligation as of September 30,
1996.

   The Company is subject to various contingencies which arise primarily from
interpretation of federal and state laws, and regulations affecting the oil and
gas industry. Such contingencies include differing interpretations as to the
prices at which oil and gas sales may be made, the prices at which royalty
owners may be paid for production from their leases and other matters. Although
management believes it has complied with the various laws and regulations,
administrative rulings and interpretations thereof, adjustment could be required
as new interpretations and regulations are issued. In addition, production
rates, marketing and environmental matters are subject to regulation by various
federal and state agencies.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

STRATEGY

   The Company focuses on acquisitions where a substantial portion of the value
is in proved developed producing reserves which are currently generating cash
flow. Management is relatively impartial as to the acquisition of gas versus
oil. Although management would prefer operatorship of the properties, the
Company does not pass up any opportunities for that reason. At this point, the
Company has not restricted itself to seeking acquisitions in specific
geographical regions.

   Along with the acquisition of properties, the Company looks for ways to
exploit existing and acquired reserves by increasing production rates,
accelerating reserve recoveries and, improving and extending the economic
viability of the properties. Exploitation activities may include workovers,
recompletions, new stimulation technology, development drilling, horizontal
drilling, pressure maintenance projects, and other methods of enhanced recovery.
Although the Company does not participate in rank exploration, it may
participate in exploratory drilling on leases associated with existing or
acquired producing properties.

   While the Company is actively pursuing these avenues, there can be no
assurance that it will have successful results in its acquisition, exploitation
and exploration efforts. There is a tremendous amount of competition in the
industry and the prices paid for in-place reserves make it difficult to achieve
attractive rates of return.

ACQUISITION AND DIVESTITURE ACTIVITIES

   The Company has closed four acquisitions in 1996. See Note 5.

   The Company is in discussion with a third party concerning the sale of its
short lived South Timbalier 198 property. South Timbalier 198 is the Company's
only offshore property and is the last remaining significant property not
acquired under the strategy being executed by current management. There is no
assurance that a sale will take place.

DEVELOPMENT ACTIVITIES

   With the completion of two new wells on the Throckmorton property, located in
Throckmorton County, the Company has successfully completed nine development
wells since it changed its focus in mid 1994 to acquisitions. All of these
development wells have been drilled on properties acquired by the Company since
mid 1994. The Company plans additional development activities to take place
primarily in 1997.

RESULTS OF OPERATIONS

Nine Months Ended September 30, 1995 compared with Nine Months Ended
September 30, 1996

   Oil and gas revenues increased from $2.8 million in the first nine months of
1995 to $7.4 million during the comparable period in 1996 as a result of an
increase in oil and gas production as due to acquisitions and improved prices.
Gas production for the nine months increased from approximately 3.1 MMCF per day
in the first nine months of 1995 to approximately 7 MMCF per day for the
comparable period in 1996. Oil production increased from 302 barrels per day to
487 barrels per day in 1996. The average prices received for gas increased from
$1.50 per Mcf for the first nine months of 1995 production to $2.37 per Mcf for
the first nine months of 1996, the average price received for oil production
increased from $16.82 per Bbl during the first nine months of 1995 to $19.96 per
Bbl during the comparable period in 1996.

   Lease operating expenses increased from $761,000 in the first nine months of
1995 to $1.6 million for the comparable period in 1996, as a result of the
additional wells added through the acquisitions and development drilling.
Depreciation and amortization expense also increased from $811,000 during the
first nine months of 1995 to $1.7 million for the comparable period in 1996 as a
result of an increase in asset growth from acquisition and production, and a
decline in gas reserves from the Company's offshore properties.

   Administrative expenses increased from $1.2 million for the first nine months
of 1995 to $1.7 million for the comparable period in 1996, due to the
acquisition activities and related increases in overhead, as well as the cost of
conversion of the Preferred Stock and related Shareholder costs.

   Interest expense increased from $159,000 in the first nine months of 1995 to
$662,000 for the comparable period in 1996 as a result of additional bank
indebtedness incurred for the acquisitions.

Three Months Ended September 30, 1995 compared with Three Months Ended
September 30, 1996

   Oil and gas revenues increased from $953,000 in the third quarter of 1995 to
$2.6 million during the comparable period in 1996 due to an increase in oil and
gas production as a result of acquisitions and improved prices. Gas production
increased from approximately 3.4 MMCF per day in the third quarter of 1995 to
approximately 7.9 MMCF per day for the comparable period in 1996. Oil production
increased from 306 barrels per day in 1995 to 505 barrels per day. The average
prices received for gas increased from $1.48 per Mcf for the third quarter of
1995 production to an average of $2.37 per Mcf for the third quarter of 1996,
the average price received for oil production increased for oil from $16.87 per
Bbl during the third quarter of 1995 to $20.42 per Bbl during the comparable
period in 1996.

   Lease operating expenses increased from $230,000 in the third quarter of 1995
to $597,000 in the comparable period in 1996 as a result of the additional wells
added through the acquisitions and development drilling. Depreciation and
amortization expense also increased from $286,000 during the third quarter of
1995 to $699,000 for the comparable period in 1996 as result of an increase in
asset growth from acquisition and production, and a decline in gas reserves from
the Company's offshore properties.

   Administrative expenses increased from $452,000 for the third quarter of 1995
to $627,000 for the comparable period in 1996 due to the acquisition activities
and related increases in overhead as well as the cost of conversion of the
Preferred Stock and related Shareholder costs.

   Interest expense increased from $16,000 in the third quarter of $245,000 for
the comparable period in 1996 as result of additional bank indebtedness incurred
for the acquisitions.

          FINANCIAL CONDITION AND RESULTS OF OPERATIONS--(CONTINUED)

LIQUIDITY AND CAPITAL RESOURCES

   The Company has improved its overall financial condition in the last three
years through restructuring its equity and its financing arrangements with its
bank. The Company however, must continually seek additional sources of financing
in order to support its acquisition and exploitation activities. The Company has
financed these acquisitions, including the Fremont acquisition, through the use
of working capital, bank borrowings and equity. The Company has financed the
acquisition of Texan Gardens and Cosden with increased bank borrowings based on
increases in its reserve base resulting from such acquisitions and the Bridge
Loan. The Company currently plans to utilize internally generated cash flows and
bank financing to support future acquisitions together with other types of
financing, which may be more expensive, such as mezzanine, production payments
and additional equity financing. However, there is no assurance that the Company
will be successful in obtaining such additional financing. In June 1996, the
Company completed a private sale of approximately 1.08 million restricted shares
of Common Stock at an average price of $.34 per share. At November 1, 1996, the
Company has essentially fully utilized its bank financing capabilities and,
therefore, future bank borrowings will be limited by its additions to its
borrowing base and Bridge Loan. The Company has revised its Bank Credit
Agreement (see note 3). The Company intends to repay the current portion of Bank
Debt from cash flow provided by operations and additional funds raised through
the private placement of equity.

   The Company is currently negotiating with private investors regarding a
potential private placement of approximately $4 million of equity. Certain of
these private investors are also considering investing approximately $1.25
million in an exploitation project on the Eastern Shelf of the Permian Basin
with the Company. There is no assurance that either of these private placements
will take place.

NEW ACCOUNTING STANDARDS

   In March 1995, the FASB issued SFAS No. 121, "Accounting for the Impairment
of Long-Lived Assets for the Long-Lived Assets to be Disposed Of" ("SFAS 121"),
which is effective for fiscal years beginning after December 15, 1995. Effective
January 1, 1996, the Company adopted SFAS 121 which requires that long-lived
assets (i.e., property, plant and equipment) held and used by an entity be
reviewed for impairment whenever events or changes in circumstances indicate
that the net book value of the asset may not be recoverable. The Company did not
have a material impact upon adoption of SFAS 121.

by the Lender and each payment made by the Borrower.  Each time such an Advance
is made against or payment (including a prepayment) is made on the Note, the
Lender is authorized but not required to make a notation on the ledger forming a
part thereof reflecting the amount advanced or paid and the date thereof;
provided, however, that the failure of the Lender to do so shall not relieve the

shall be deemed rebuttably presumptive evidence of the principal amounts owing

the $25.00 Preferred Stock issuance  a prepayment in the amount of such funds
shall be due and payable and shall be applied first to accrued and unpaid
interest and then to the principal balance of the Note.

          Interest as it accrues on principal amounts evidenced by the Note and
calculated as provided herein and in the Note shall be due and payable monthly
commencing on the last day of August, 1996, and continuing thereafter on the
last day of each succeeding calendar month while any amount remains owing on the
Note and upon the Termination Date, the interest payment in each instance to be

made in immediately available funds; shall be deemed received by the Lender on
the next Business Day following receipt if such receipt is after 2:00 p.m. on
any Business Day; and shall be made at the offices of the Lender at 910 Travis,
Houston, Texas 77002, provided, however, the Lender may, upon notice to the

to such production, and such Security Documents further provide that all such
revenues and proceeds which may be so collected by the Lender pursuant to such
assignment shall be applied to the payment of the Note and the satisfaction of
all other Debt to be secured by such Security Documents.  The Lender and the
Borrower expressly acknowledge and agree that so long as no Event of Default
shall have occurred and be continuing, the Lender shall be entitled only to
payment on the Note as set forth in the preceding paragraphs of this Section
2.3, and the Borrower, to the extent of its rights apart from this Agreement,
shall be entitled to receive all proceeds of production directly from the
relevant purchasers or parties accounting for proceeds from the sale of
production.  In connection with the rights of the Lender to all proceeds of
production upon the occurrence and continuation of an Event of Default, the

Highest Lawful Rate) per annum, calculated on a year of three hundred sixty-five
(365) or three hundred sixty-six (366) days, as the case may be, and counting
the actual number of days elapsed.  Should default occur in the payment of the
Note and collection proceedings be instituted, all past due interest and
principal under the Note shall bear interest at the lesser of the Highest Lawful
Rate or the Default Rate per annum, calculated on a year of three hundred sixty-
five (365) or three hundred sixty-six (366) days, as the case may be, and
counting the actual number of days elapsed; and if no Highest Lawful Rate
exists, all past due interest and principal under the Note shall bear interest
at the Default Rate, calculated on a year of three hundred sixty-five (365) or
three hundred sixty-six (366) days, as the case may be, and counting the actual
number of days elapsed.

Borrower shall pay to the Lender a commitment fee equal to one percent (1%) per
annum (computed on the basis of a year of three hundred sixty-five (365) or
three hundred sixty-six (366) days, as the case may be, and counting the actual
number of days elapsed) of the average daily Unused Amount of the Commitment
during the period of determination.  This commitment fee shall commence to
accrue as of the date of this Agreement and shall cease to accrue on the earlier
of the Termination Date or the day the Commitment is otherwise terminated
hereunder.  Accrued commitment fees under this Section 2.5 shall be payable on
September 1, 1996 and on the first day after the earlier of the Termination Date
or the day the Commitment is otherwise terminated hereunder and shall be
determined for each period from

                                       12

and inclusive of the date on which this Agreement was executed or the previous
payment date, as the case may be, but exclusive of the date of payment.

          2.6  Facility Fee.  As consideration for the Commitment, the Borrower
               ------------                                                    
shall pay to the Lender on the date on which this Agreement is executed by the
Borrower and the Lender a facility fee equal to $25,000.00.

          2.7  General Provisions Relating to Interest.  It is the intention of
               ---------------------------------------                         
the parties hereto to comply strictly with the applicable usury Laws as in
effect from time to time; and in this connection, there shall never be taken,
reserved, contracted for, collected, charged or received on any Loan or any
other Obligation interest in excess of that which would accrue at the Highest
Lawful Rate.  For purposes of Article 5069-1.04, Vernon's Texas Civil Statutes,
                                                          -------------------- 
as amended, the Borrower agrees that the Highest Lawful Rate shall be the
"indicated rate ceiling" as defined in such article, provided that the Lender
may also rely, to the extent permitted by applicable Laws, on alternative
maximum rates of interest under such other applicable Laws, if greater.

          Notwithstanding anything herein or in the Note or the other Loan
Documents to the contrary, if during any Limitation Period the calculation of
interest at the rate otherwise due to the Lender would result in interest in
excess of that which would accrue at the Highest Lawful Rate, then during such
Limitation Period, the interest rate to be charged on the Obligations shall be
the Highest Lawful Rate, and the requirement of the Borrower for the payment of
other amounts, if any, constituting interest, shall be suspended only to the
extent that such fees are, when added to interest accruing on the Note and other
Obligations, if any, in excess of the Highest Lawful Rate.  During any period of
time following a Limitation Period, to the extent permitted by Laws applicable
to the Lender, the interest rate to be charged on the Obligations shall remain
at the Highest Lawful Rate until such time as there has been paid to the Lender:
(a) the amount of interest in excess of the amount accruing at the Highest
Lawful Rate that the Lender would have received during the Limitation Period if
the otherwise applicable rate had been in effect at all times and (b) all
interest and fees otherwise payable to the Lender hereunder as if the otherwise
applicable rate had been in effect at all times during such Limitation Period.

          If under any circumstances the aggregate amount paid on the
Obligations includes amounts that are by Law deemed to be interest which exceed
the Highest Lawful Rate (the "excess interest"), the Borrower stipulates that
                              ---------------                                
such payment and collection will have been and will be deemed to have been, to
the fullest extent permitted by applicable Laws, the result of mathematical
error on the part of the Borrower and the Lender, and the Lender shall promptly
credit the amount of such excess interest on the principal amount of the
outstanding Obligations, or if the principal amount of the Obligations shall
have been paid in full, refund the excess interest to the Borrower.  In the
event that the maturity of the

                                       13
<PAGE>
 
Note is accelerated by reason of an election of the Lender resulting from any
Event of Default or by reason of operation of Subsection 7.3(a), or in the event
of any prepayment, then such consideration that constitutes interest under Laws
applicable to the Lender may never exceed the Highest Lawful Rate, and excess
interest, if any, provided for in the Note, this Agreement or otherwise shall be
cancelled automatically by the Lender as of the date of such acceleration or
prepayment and, if theretofore paid, shall be credited by the Lender on the
principal amount of the Obligations, or if the principal amount of the
Obligations shall have been paid in full, refunded by the Lender to the
Borrower.

          All sums paid, or agreed to be paid, to the Lender for the use,
forbearance, and detention of the proceeds of the Loans shall, to the extent
permitted by applicable Law, be amortized, prorated, allocated, and spread
throughout the full term of the Obligations 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.

          2.8  Loans to Satisfy Obligations.  The Lender may, but shall not be
               ----------------------------                                   
obligated to, make Loans and apply proceeds thereof to the satisfaction of any
warranty, representation, covenant or other Obligation of the Borrower contained
in this Agreement or the other Loan Documents and which are necessary, in the
good faith opinion of the Lender, to enforce its Rights, protect or preserve the
Collateral or the Liens thereon in favor of the Lender and the priorities
thereof, or avoid a Material Adverse Effect, and contemporaneously with so
doing, the Lender shall furnish the Borrower written notice as to the amount and
date of any such Loan. The Lender shall not advance funds pursuant to this
Section without notifying the Borrower of the warranty, representation, covenant
or other Obligation to be satisfied by such proposed advance of funds and shall
give the Borrower fifteen (15) days from the date of such notice to satisfy such
warranty, representation, covenant or other Obligation.  Any funds so advanced
and applied shall be evidenced by the Note, shall be payable on demand and shall
bear interest at the Default Rate from the time of the making of such Loan until
the time of repayment.

option to prepay, at any time without premium or penalty, all or any part of the
balance outstanding on the Note.  Any such prepayments of Debt evidenced by the
Note shall be applied to the payment of accrued and unpaid interest and to the
reduction of principal as elected by the Borrower.

          2.10      Yield Protection.  If at any time after the date hereof, and
                    ----------------

insurance or capital (including any allocation of capital requirements or
conditions), or similar requirements, or any interpretation or administration
thereof by any Tribunal, central bank or comparable agency

charged with the interpretation, administration or compliance of the Lender with
any of such requirements, has or would have the effect of (a) increasing the
costs of the Lender relating to the Obligations of the Borrower or (b) reducing
the yield or rate of return of the Lender on the Obligations of the Borrower to
a level below that which the Lender could have achieved but for the adoption or
modification of any such requirements, the Borrower shall, within fifteen (15)
days of any request by the Lender, pay to the Lender such additional amounts as
(in the good faith judgment of the Lender based on reasonable computation) will
compensate the Lender for such increase in costs or reduction in yield or rate
of return of the Lender.  The request by the Lender to the Borrower for such
additional amounts shall also set forth the computation by the Lender of such
requested additional amounts.  No failure by the Lender to demand immediate
payment of any additional amounts payable under this Section 2.10 shall
constitute a waiver of the right of the Lender to demand payment of such amounts
at any subsequent time.  Nothing contained in this Section 2.10 shall be
construed or so operate as to require the Borrower to pay any interest, fees,
costs or charges greater than permitted by applicable Laws.

          2.11      Automatic Debit Authority. The Borrower hereby grants to the
                    -------------------------

including, without limitation, the Borrower, to debit automatically from the
operating accounts of the Borrower maintained at the Lender any and all
repayments of Debt due and payable hereunder or under the Note, fees due and
payable hereunder and costs and expenses of the Lender the Borrower is obligated
to reimburse hereunder.

          2.12      Security Interests in Deposits.  To secure the Debt of the
                    ------------------------------                            
Borrower evidenced by the Note, the Borrower hereby grants to the Lender a
security interest against all funds or other Property of the Borrower now or
hereafter or from time to time on deposit with or in the possession of the
Lender, including, without limitation, all certificates of deposit and other
depository accounts whether such have matured or the exercise of such right of
the Lender results in loss of interest or other penalty on such deposits.  Upon
any Event of Default the Borrower may exercise any and all remedies against such
funds or Property as a secured party under the Uniform Commercial Code as
adopted in the State of Texas.  Nothing in this Section shall be construed to
limit any right of offset afforded the Lender.

condition and the results of the operations of the Borrower in all material
respects, as of the dates and for the periods stated therein.

               ---------------

delivery and performance by the Borrower of this Agreement, the other Loan
Documents or any other agreement contemplated hereby or the repayment by the
Borrower of the Obligations.

          4.8  Compliance with Laws.  Neither the business nor any of the
               --------------------                                      
activities of the Borrower as presently conducted violates any applicable Law,
the result of which violation would have a Material Adverse Effect.  The
Borrower possesses all licenses, approvals, registrations, permits and other
authorizations necessary to enable it to carry on its businesses in all material
respects as now conducted.  All such licenses, approvals, registrations, permits
and other authorizations are in full force and effect.  Furthermore, the
Borrower does not have any reason to believe that it will be unable to obtain
the renewal of any such licenses, approvals, registrations, permits and other
authorizations in due course. No transaction contemplated by this Agreement or
the other Loan Documents is in violation of any regulation promulgated by the
Board of Governors of the Federal Reserve System, including, without limitation,
Regulations G, U or X.

Borrower has duly and properly filed or extended the date for filing all Tax

Borrower's books with respect to any Taxes are adequate, and

                                       19

to, or had an obligation to contribute to, any Multi-employer Plan.  Since the
effective date of ERISA, no Reportable Event or Prohibited Transaction has
occurred with respect to any Plan of the Borrower.  Each Plan established or
maintained by the Borrower meets the minimum funding standards of Section 302 of
ERISA and otherwise is in compliance with all applicable provisions of ERISA.
The Borrower has filed all reports required by ERISA and required to be filed by
it with respect to each Plan.  The Borrower does not have any knowledge of any
event that could result in any material liability of the Borrower to the PBGC.
The Borrower has met all requirements with respect to funding the Plans imposed
on the Borrower by ERISA or the PBGC.  Since the effective date of Title IV of
ERISA, there have not been any, nor are there now existing any, events or
conditions that would permit any Plan to be terminated under circumstances that
would cause the lien provided under Section 4068 of ERISA to attach to the
assets of the Borrower. The value of the Plans' benefits guaranteed under Title
IV of ERISA on the date hereof does not exceed the value of such Plans' assets
allocable to such benefits as of the date of this Agreement and shall not be
permitted to do so hereafter.

                -------------
