Preliminary Available Amount has been issued and the gross proceeds
thereof received by the Company and (b) all Designated Debt for the
aggregate Qualifying Amount of Junior Securities actually issued, as

additional date, if any, on which Junior Securities have been issued
shall be aggregated.  For example, if there is only one issuance of
Junior Securities and such issuance is in a Qualifying Amount of
$75,000,000, the Facility A Maximum Amount will thereafter be



determined according to Table Four of EXHIBIT E, the Preliminary
Available Amount will thereafter be determined according to Table Four
of EXHIBIT F, and the Qualifying Date and the Achievement Date will be
the same.  For example, if there are two issuances of Junior
Securities, one in the amount of $75,000,000 and a later one in the
amount of $50,000,000, the Qualifying Date will be the date of the
first issuance, which will also be the Achievement Date for the
$75,000,000 level in both EXHIBIT E and EXHIBIT F, and the Facility A
Maximum Amount will be determined according to Table Four of EXHIBIT E
and the Preliminary Available Amount will be determined according to
Table Four of EXHIBIT F until the date of the second issuance; the
date of the second issuance will be the Achievement Date for the
$125,000,000 level in both EXHIBIT E and EXHIBIT F, and the Facility A
Maximum Amount will thereafter be determined according to Table Two of
EXHIBIT E and the Preliminary Available Amount will thereafter be

Readvance if by virtue thereof the aggregate of the Facility A
Readvances of such Bank at any one time outstanding would exceed such
Bank's Commitment Percentage of the Facility A Unused Commitment then
in effect, and (B) if a Bank fails to make a Facility A Readvance as
and when required hereunder and the Company subsequently makes a
repayment on the Facility A Notes, such repayment shall be split among
the non-defaulting Banks ratably in accordance with their respective
Commitment Percentages until each Bank has its Commitment Percentage
of all of the outstanding Facility A Loans, and the balance of such
repayment shall be divided among all of the Banks in accordance with
their respective Commitment Percentages. 

          (4)  Notwithstanding anything in this Agreement to the
contrary, no Bank shall be required to make a Facility A Readvance
(but each Bank shall permit Rollovers) during the existence of an
Engineering Shortfall.

                                 -42-


     (b)  FACILITY B LOANS.

          (1)  Subject to the conditions herein (including CLAUSE (6)
of this section), from time to time on or after the date hereof and
prior to the Facility B Termination Date, each Bank shall make Loans
under this SECTION 2.1(b) to the Company in an aggregate principal
amount at any one time outstanding up to but not exceeding such Bank's
Facility B Commitment; PROVIDED HOWEVER, that the foregoing
notwithstanding, prior to the Qualifying Date or, if no Qualifying
Date occurs, July 1, 1994, the aggregate Facility B Loans shall never
exceed the aggregate of the Facility B Commitments of all Banks minus
the Unavailable Commitment.  Subject to the conditions herein
(including CLAUSE (6) of this section), any such Facility B Loan
repaid prior to the Facility B Termination Date may be reborrowed
pursuant to the terms of this Agreement; PROVIDED, that any and all
such Facility B Loans shall be due and payable in full on the
Facility B Maturity Date.

          (2)  Concurrently with the delivery of each Independent
Engineering Report and related Coverage Report required or permitted
hereby, there shall be determined, based on the Most Recent
Engineering Report and Approved Assumptions, the total maximum amount
of Facility B Loans and Letters of Credit to be available to the
Company hereunder and under the Letter of Credit Agreement without
violation of any Required Ratio.  Upon each such delivery, the Company
may by notice to the Co-Agents designate as the Available Amount any
amount (not to exceed the Preliminary Available Amount as of the most
recent Achievement Date (or, if no Achievement Date occurs, the
Preliminary Available Amount then in effect) according to the
applicable table in EXHIBIT F) equal to or less than such total
maximum amount.  The Available Amount so designated shall remain in
effect as the Available Amount until the next determination under this
SECTION 2.1(b)(2).  If no amount lesser than (a) or (b) in this
sentence is designated in accordance with this SECTION 2.1(b)(2), the
Available Amount shall be the lesser of (a) the Preliminary Available
Amount then in effect according to the applicable table in EXHIBIT F
or (b) such total maximum amount.

          (3)  Notwithstanding anything in this Agreement to the
contrary, (A) no Bank shall be required to make Facility B Loans at
any one time outstanding in excess of such Bank's Commitment
Percentage of the lesser of (x) the aggregate of the Facility B
Commitments of all Banks then in effect (minus, prior to the
Qualifying Date or, if no Qualifying Date occurs, July 1, 1994, the
Unavailable Commitment) and (y) the difference between (i) the
Available Amount and (ii) the aggregate Letter of Credit Liabilities,
and (B) if a Bank fails to make a Facility B Loan as and when required
hereunder and the Company subsequently makes a 

                                 -43-


repayment on the Facility B Notes, such repayment shall be split among
the non-defaulting Banks ratably in accordance with their respective
Commitment Percentages until each Bank has its Commitment Percentage
of all of the outstanding Facility B Loans, and the balance of such
repayment shall be divided among all of the Banks in accordance with
their respective Commitment Percentages.

          (4)  Notwithstanding anything in this Agreement to the
contrary, no Bank shall be required to make Facility B Loans (but each
Bank shall permit Rollovers) during the existence of an Engineering
Shortfall.

          (5)  Upon each delivery of the financial statements required
by SECTION 9.1(b) and the Independent Engineering Report required by
SECTION 9.1(g), the Company may request the Banks to extend the
Facility B Termination Date then in effect by a period not to exceed
one year (but in no event later than December 31, 1998).  Such request
shall be made by giving its written request to the Agent specifying
the date to which the Facility B Termination Date is to be extended. 
The Agent, the Co-Agents and the Banks shall consider any such request
in a timely fashion and in good faith and in light of all relevant
facts and circumstances at the time of such request, but the granting
of any such extension shall be at all times within the sole and
absolute discretion of the Agent, the Co-Agents and the Banks.  The
granting of any such extension would require the unanimous consent of
the Agent, the Co-Agents and the Banks and may be conditional on such
terms and conditions as the Agent, the Co-Agents and the Banks may in
their discretion propose.  Failure to obtain such an extension shall
not IPSO FACTO either constitute or excuse a Default or an Event of
Default.

          (6)  Notwithstanding anything contained in this Section,
except in the case of a Rollover or a Facility B Loan to satisfy a
Reimbursement Obligation pursuant to SECTION 4.1, the Company may not
obtain Facility B Loans at any time unless the Facility A Unused
Commitment is equal to zero at such time.

     2.2. TERMINATIONS, REDUCTIONS AND CHANGES OF COMMITMENTS AND
FACILITY A MAXIMUM AMOUNTS.

     (a)  MANDATORY.  (1)  On the Facility A Termination Date, all
Facility A Commitments shall be terminated in their entirety.  On the
Facility B Termination Date, all Facility B Commitments shall be
terminated in their entirety.

          (2)  In the event that the Company is required to make a
prepayment of the Facility A Loans pursuant to SECTION 3.2(b)(2)(A) or
3.2(b)(2)(B), the Facility A Maximum Amount for the Applicable 

                                 -44-


Period then in effect shall be reduced by the amount of such
prepayment and an amount equal to such prepayment shall be deducted
from the Facility A Maximum Amounts for each subsequent Applicable
Period PRO RATA according to their respective amounts in effect
immediately prior to such reduction; PROVIDED, that if such PRO RATA
deduction does not result in compliance by the Company with all
Required Ratios, such amount shall be reallocated among such
subsequent Applicable Periods (and, if necessary, to the aggregate
Facility B Commitments) as the Company shall direct to the extent
necessary to bring the Company into compliance with all Required
Ratios.

          (3)  The Company shall from time to time reduce the
aggregate Facility B Commitments for present and future Applicable
Periods (and, if necessary, the Facility A Maximum Amount) to the
extent necessary to bring the Company into compliance with all
Required Ratios.  Any such reduction or termination of Commitments
shall be made against the Facility B Commitments; PROVIDED, that if
the Company can comply with all Required Ratios only by reducing the
Facility A Maximum Amount, the Company may reduce or terminate the
Facility A Maximum Amount, but only to the extent necessary to achieve
such compliance.  Any such reduction shall be accomplished within 10
Business Days after demand therefor by the Agent; PROVIDED, that in
the case of any noncompliance with Required Ratios resulting solely
from an Engineering Shortfall, the Company shall remedy such
noncompliance, but no Event of Default shall occur until the
expiration of the cure period provided in SECTION 10.1(e).

          (4)  In addition, in the event the Company is required to
make a prepayment of Facility A Loans pursuant to SECTION 3.2(b)(3),
an amount equal to such prepayment shall be deducted from the Facility
A Maximum Amounts for present and future Applicable Periods (and, if
necessary, to the aggregate Facility B Commitments) in such manner as
the Company may direct to the extent necessary to bring the Company
into compliance with all Required Ratios.

          (5)  Except where reductions in the Facility A Maximum
Amounts for the Applicable Periods are made PRO RATA pursuant to
SECTION 2.2(a)(2), if at any time the Facility A Maximum Amount is
reduced for any future Applicable Period pursuant to
SECTION 2.2(a)(2), 2.2(a)(3) or 2.2(a)(4) to bring the Company in
compliance with all Required Ratios, the Facility A Maximum Amount for
the Applicable Period in effect at such time and each Applicable
Period subsequent thereto and prior to such future Applicable Period
shall be reduced by a like amount.

                                 -45-


     (b)  THE COMPANY'S OPTION.

          (1)  The Company shall have the right to terminate or reduce
the unused portion of the Facility B Commitments at any time or from
time to time; PROVIDED that (A) the Company shall give notice of each
such termination or reduction to the Agent as provided in SECTION 5.5;
(B) each such partial reduction shall be in an integral multiple of
$5,000,000, and (C) the Company may not cause the Available Amount to
be less than the aggregate principal amount of the Facility B Loans
then outstanding plus the Letter of Credit Liabilities then
outstanding.  No voluntary reduction in the Available Amount prior to
any scheduled reduction in the Available Amount shall affect the
Available Amount after such scheduled reduction date unless such
voluntarily reduced Available Amount is less than the amount scheduled
to be the Available Amount after such scheduled reduction date, in
which case the Available Amount after such scheduled reduction date
shall be no greater than such voluntarily reduced Available Amount. 
Reference is made to SECTION 2.8 for restrictions on the Company's
right to increase the Available Amount under certain circumstances.

          (2)  The Company shall have the right to (A) terminate or
reduce the Facility A Unused Commitment at any time or from time to
time or (B) reduce the Facility A Maximum Amount for any particular
Applicable Period at any time or from time to time; PROVIDED that (i)
the Company shall give notice of each such termination or reduction to
the Agent as provided in SECTION 5.5, (ii) each such partial reduction
shall be in an integral multiple of $5,000,000, (iii) the Company may
not cause the Facility A Maximum Amount to be less than the aggregate
principal amount of the Facility A Loans then outstanding; and (iv)
the Company shall not terminate or reduce the Facility A Unused
Commitment unless at the same time the aggregate Facility B
Commitments are terminated or reduced by the same amount.  Reductions
in the Facility A Maximum Amount may be applied to any Applicable
Period at the option of the Company PROVIDED that after such
application the Company is in compliance with all Required Ratios.  

     (c)  NO REINSTATEMENT.  NO reduction in or termination of the
Commitments pursuant to SECTION 2.2 and no reduction in any Facility A
Maximum Amount may be reinstated without the written approval of the
Agent and all Banks.

     2.3. FEES.  (a) In consideration of the Commitments, the Company
shall pay to the Agent for the account of each Bank in accordance with
its Commitment Percentage commitment fees (the "COMMITMENT FEES") for
the period from the date of the effectiveness of this Agreement to and
including the date the last of the Commitments are terminated at a
rate per annum equal to the 

                                 -46-


sum of (a) 1/2% of the unused portion of the Available Commitment and
(b) 1/4% of the Unavailable Commitment.  The Commitment Fees shall be
computed for each day and shall be based on the unused portion of the
Available Commitment and the Unavailable Commitment for such day. 
Accrued Commitment Fees shall be payable in arrears on the date of the
initial Loans or Facility A Readvances, within three days after demand
therefor on or about the Quarterly Dates, and within three days after
demand therefor on or about the relevant Termination Date.  

     (b)  In consideration of the Commitments and of the agreement of
the Banks to enter into this Agreement, the Company shall pay to the
Agent for the account of each Bank in accordance with its Commitment
Percentage a facility fee in an amount equal to .125% of such Bank's
Commitment Percentage of the Unavailable Commitment.  Such facility
fee shall be due on the Qualifying Date and will never be due if the
Qualifying Date does not occur.  

     (c) All past due fees payable pursuant to this section shall bear
interest at the Post-Default Rate.  Upon receipt, the Agent shall
disburse such fees to the Banks in accordance with their Commitment
Percentages.

     2.4. AFFILIATES; LENDING OFFICES.

     (a)  Any Bank may, if it so elects, fulfill its Commitment as to
any Eurodollar Loan by causing a branch, foreign or otherwise, or
Affiliate of such Bank to make such Loan and may transfer and carry
such Loan at, to or for the account of any branch office or Affiliate
of such Bank; PROVIDED that in such event, for the purposes of this
Agreement, such Loan shall be deemed to have been made by such Bank
and the obligation of the Company to repay such Loan shall
nevertheless be to such Bank and shall be deemed to be held by such
Bank, to the extent of such Loan, for the account of such branch or
Affiliate.

     (b)  Notwithstanding any provision of this Agreement to the
contrary, each Bank shall be entitled to fund and maintain its funding
of all or any part of its Loans hereunder in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement
all determinations hereunder shall be made as if such Bank had
actually funded and maintained each Eurodollar Loan during each
Interest Period through the purchase of deposits having a maturity
corresponding to such Interest Period and bearing an interest rate
equal to the applicable Eurodollar Base Rate for such Interest Period.

     2.5. SEVERAL OBLIGATIONS.  The failure of any Bank to make any
Loan to be made by it on the date specified therefor shall not 

                                 -47-


relieve any other Bank of its obligation to make its Loan on such
date, but neither the Agent nor any Bank shall be responsible for the
failure of any other Bank to make a Loan to be made by such other
Bank.

     2.6. NOTES.  The Loans made by each Bank shall be evidenced by a
single Facility A Note or Facility B Note, as the case may be, of the
Company (each, together with all renewals, extensions, modifications
and replacements thereof and substitutions therefor, a "NOTE") dated
the date hereof, payable to the order of such Bank in a principal
amount equal to the Commitment of such Class of such Bank as
originally in effect and otherwise duly completed.  Each Bank is
hereby authorized by the Company to endorse on the schedule (or a
continuation thereof) attached to each Note of such Bank, to the
extent applicable, the date, amount and Type of and the Interest
Period for each Loan made by such Bank to the Company hereunder, and
the amount of each payment or prepayment of principal of such Loan
received by such Bank; PROVIDED that any failure by such Bank to make
any such endorsement shall not affect the obligations of the Company
under such Note, in respect of such Loan, or hereunder.

     2.7. OPTIONAL RESERVE REPORT.  The Company may from time to time
at its option, exercisable by giving written notice to the Co-Agents
not more often than once in any Calculation Period, provide to the
Co-Agents an Independent Engineering Report.  Upon the receipt of such
notice, the Co-Agents shall consult with the Company to determine new
Approved Assumptions, which shall be furnished to the Banks by a
notice as provided in the definition of "Approved Assumptions" and
shall be subject to the approval by Banks with aggregate Commitment
Percentages of 75% or more as provided therein.  The Optional Reserve
Report shall be based on the new Approved Assumptions and shall be
accompanied by a Coverage Report as of the date such Optional Reserve
Report is furnished.  The Annual Debt Service Coverage Ratio, the
Alternate Annual Debt Service Coverage Ratio, the TLOR Coverage Ratio
and the SLOR Coverage Ratio (and the Applicable Margin) shall each be
redetermined in accordance with this Agreement on the basis of each
such Optional Reserve Report and Coverage Report, and the Available
Amount recalculated as provided in SECTION 2.1(b)(2). 

     2.8. RELEASE OF MORTGAGES.  The Company shall be entitled to a
release of the Mortgaged Properties from the liens, assignments and
security interests of the Deed of Trust and the other Mortgages,
PROVIDED that (a) immediately before and immediately after giving
effect to such release, no Default shall have occurred and be
continuing; and (b) the Annual Debt Service Coverage Ratio and the
SLOR Coverage Ratio (each calculated assuming the Available Amount is
fully drawn and that the aggregate unpaid principal 

                                 -48-


balance of the Facility A Notes is equal to the Facility A Maximum
Amount) immediately before and immediately after giving effect to any
such release shall be at least 1.25 to 1.00 and 2.00 to 1.00,
respectively.  At any time on or after the Qualifying Date, but prior
to July 1, 1994, the Company may choose not more often than once by
giving written notice to the Co-Agents to recalculate the Annual Debt
Service Coverage Ratio and the SLOR Coverage Ratio to determine if the
Company qualifies for release of the Mortgaged Properties pursuant to
this section; such recalculation shall be based on new Approved
Assumptions to be determined in connection with such recalculation by
Banks with Commitment Percentages of 75% or more and using the
Independent Engineering Report most recently furnished in accordance
with this Agreement.  Notwithstanding any other provision of this
Agreement to the contrary, should both (x) the Company at any time
designate as the Available Amount an amount less than the maximum
amount then offered to it as the Available Amount and (y) as a result
the Company shall obtain the release of any Mortgaged Properties, the
Available Amount may never thereafter exceed the amount so designated
by the Company.

     2.9. USE OF PROCEEDS.  The proceeds of the Loans shall be used by
the Company for working capital and for general corporate purposes and
may not be utilized (a) to pay dividends other than usual dividends in
the ordinary course of business or (b) for the buyout or acquisition
of any business unless the board of directors of such Person or any
other similar body has first approved such buyout or acquisition.

     2.10.     ORIGINAL CREDIT DOCUMENTS NOT TERMINATED.  The
execution and delivery of this Agreement and the other Credit
Documents in connection with this Agreement, including the Notes, does
not and shall not constitute payment, prepayment or novation of any
indebtedness outstanding under the Revolving and Term Credit Agreement
dated as of May 20, 1992, by and among the parties hereto, as amended,
or the notes outstanding thereunder on the date hereof (the "ORIGINAL
NOTES").  The Original Notes have been marked "renewed" rather than
"paid".  All Liens securing the Original Notes as amended and modified
from time to time by the Credit Documents executed and delivered
concurrently with this Agreement are hereby ratified, confirmed,
extended, renewed and brought forward as security for the Notes and
all other Obligations of the Company described therein as being
secured thereby.

     2.11.     SALE OF CERTAIN PROPERTIES.  Notwithstanding the
provisions of SECTIONS 2.2, 2.8 and 3.2, the sale of the properties by
the Company pursuant to the agreement dated December 2, 1993 by and
among the Company, Santa Fe Energy Operating Partners, L.P. and Bridge
Oil U.S.A. and with respect to the Manila Village properties,
Plaquemines Parish, Louisiana, pursuant to the 

                                 -49-


agreement dated October 26, 1993, by and among the Company, Santa Fe
Energy Operating Partners, L.P., Santa Fe Oil Company and Vintage
Petroleum, Inc. shall be made with a release from the Liens of the
Security Documents, without any required prepayment and without
reducing either any Facility A Maximum Amount or any Preliminary
Available Amount.

     Section 3.  BORROWINGS, PREPAYMENTS AND SELECTION OF INTEREST
RATES.

     3.1. BORROWINGS.  The Company shall give the Agent notice of each
borrowing to be made hereunder as provided in SECTION 5.5.  Each
borrowing shall be in an amount of $1,000,000 or any integral multiple
thereof.  Not later than 1:00 p.m. on the date specified for each such
borrowing hereunder, each Bank shall make available the amount of the
Loan, if any, to be made by it on such date to the Agent, at its
Principal Office, in immediately available funds, for the account of
the Company.  The amount so received by the Agent shall, subject to
the terms and conditions of this Agreement, be made available to the
Company by depositing the same, in immediately available funds, in an
account designated by the Company and maintained with the Agent at its
Principal Office.

     3.2. PREPAYMENTS.

     (a)  OPTIONAL PREPAYMENTS.  Except as provided in SECTIONS 3,
4.2(c), 5 and 6, the Company shall have the right to prepay, on any
Business Day, in whole or in part, without the payment of any penalty
or fee, Loans at any time or from time to time; PROVIDED that the
Company shall give the Agent notice of each such prepayment as
provided in SECTION 5.5.  Eurodollar Loans may be prepaid on the last
day of an Interest Period applicable thereto.  Eurodollar Loans may
not be otherwise prepaid unless prepayment is accompanied by payment
of all compensation required by SECTION 6.5.  All optional prepayments
shall be applied to Facility B Loans and Reimbursement Obligations
until all such Facility B Loans and Reimbursement Obligations have
been repaid, then to Facility A Loans.

     (b)  MANDATORY PREPAYMENTS.  (1) The Company shall from time to
time on demand by the Agent prepay the Facility B Loans in such
amounts as shall be necessary (A) so that at all times the aggregate
outstanding principal amount of the Facility B Loans and Letter of
Credit Liabilities shall not be in excess of the Available Amount or
(B) to comply with SECTION 9.9.  Any such payment shall be allocated
between Facility B Loans and Letter of Credit Liabilities and, if to
Letter of Credit Liabilities, first to Reimbursement Obligations and
then to other obligations as the Company may elect.

                                 -50-

     In addition, the Company shall from time to time on demand by the
Agent prepay the Facility A Loans in such amounts as shall be
necessary (A) so that at all times the aggregate outstanding principal
amount of the Facility A Loans (including Facility A Readvances) shall
not be in excess of the Facility A Maximum Amount or (B) to comply
with SECTION 9.9.  


          (2)  (A) Upon any sale for cash or cash equivalent
consideration of any Proved Reserves included in the Adobe Properties
in excess of $1,000,000 in any one transaction or $5,000,000 for all
transactions, the Company shall prepay on the Business Day following
the date of such sale for application to the unpaid principal balance
of the Facility A Notes an amount equal to the greater of (i) 100% of
the total proceeds of such sale or (ii) 58% of the present worth
assigned to the property sold in the Most Recent Engineering Report.

               (B)  Except as otherwise permitted by the Mortgages,
Mortgaged Properties cannot be sold for consideration other than cash
without the approval of all Banks.  Upon any sale of any Proved
Reserves included in the Adobe Properties (other than Mortgaged
Properties) for consideration other than cash which causes the
aggregate net present value (at the discount rate included in the
Approved Assumptions on the date of each such sale) of all Adobe
Properties sold for consideration other than cash (determined in
accordance with the applicable Most Recent Engineering Report) in any
one Calculation Period to exceed $5,000,000, the Company shall prepay
on the Business Day following the date of such sale for application to
the unpaid principal balance of the Facility A Notes an amount equal
to 100% of the net present value (at the discount rate included in the
Approved Assumptions in effect on the date of such sale) of the Adobe
Properties so sold (determined in accordance with the Most Recent
Engineering Report).

               (C)  All amounts prepaid pursuant to
SECTION 3.2(b)(2)(A) or (B) shall be applied to the unpaid principal
balance of the Facility A Notes.  The Company may in its discretion
defer making the prepayment required by SECTION 3.2(b)(2) (A) or (B)
until the earlier of (i) the time the aggregate amount of such
prepayments so deferred equals or exceeds $1,000,000 or (ii) one month
after the date the first such prepayment would otherwise be due.

          (3)  Concurrently with any sale of any Proved Reserves
(whether or not included in the Adobe Properties) which would cause
the aggregate amount of such sales since the effective date of the
last calculation of compliance with the Required Ratios to exceed

                                 -51-


$20,000,000 in the aggregate, each of the Annual Debt Service Coverage
Ratio and the Alternate Annual Debt Service Coverage Ratio shall be
redetermined for the Calculation Period in which such sales occur and
for each Calculation Period thereafter to and including December 31,
1998 and the SLOR Coverage Ratio and the TLOR Coverage Ratio shall be
redetermined, in each case to the effective date of the sale on the
basis of the most recent Approved Assumptions and the Most Recent
Engineering Report and the most recent Coverage Report delivered to
the Agent pursuant to SECTION 9.1.  In making such redeterminations,
(a) the Proved Reserves (whether or not included in the Adobe
Properties) described in the Most Recent Engineering Report which are
no longer owned by members of the Combined Group (the "SOLD
PROPERTIES") shall be identified; (b) there shall be determined the
gross and net volumes of Hydrocarbons projected in the Most Recent
Engineering Report to be produced from the Petroleum Properties
(including the Sold Properties) minus the gross and net volumes of
Hydrocarbons projected in the Most Recent Engineering Report to be
produced from the Sold Properties; (c) there shall be determined by
calendar years the Net Oil and Gas Income shown in the Most Recent
Engineering Report as attributable to the Petroleum Properties
(including the Sold Properties) of members of the Combined Group minus
the Net Oil and Gas Income shown in the Most Recent Engineering Report
as attributable to the Sold Properties; and (d) the discount rate and
other factors set forth in the most recent Approved Assumptions shall
be used.  In addition to any prepayments required by SECTION
3.2(b)(2)(A) and (B), if the Company upon any such redetermination
shall not be in compliance with all Required Ratios, the Company shall
prepay on the Business Day following the date of such sale an amount
of the proceeds of all sales of any Adobe Properties not previously
prepaid for application to the unpaid principal balance of the
Facility A Notes.  The Company may in its discretion defer making the
prepayments required by the preceding sentence until the earlier of
(a) the time the aggregate amount of such prepayments so deferred
equals or exceeds $1,000,000 or (b) one month after the date the first
such prepayment would otherwise be due.

          (4)  The Company shall maintain records of all sales of
Proved Reserves, shall clearly designate each such sale as a sale of
an Adobe Property or other property, and shall otherwise maintain
books and records which enable it to comply, and to demonstrate to the
Agent on request compliance, with the obligations of the Company in
this SECTION 3.2(b).

     3.3. SELECTION OF INTEREST RATES.  Subject to SECTIONS 5, 6 and
12.8, the Company shall have the right, by giving written notice to
the Agent as provided in SECTION 5.5, either to convert any Loan (in
whole or in part) into a Loan of another Type or to 

                                 -52-


continue such Loan (in whole or in part) as a Loan of the same Type. 
Any such notice of conversion of a Loan into, or continuation of a
Loan as, a Eurodollar Loan shall specify the new Interest Period.  In
the event the Company fails to so give such notice prior to the end of
any Interest Period for any Eurodollar Loan, such Loan shall become an
Alternate Base Rate Loan on the last day of such Interest Period.  No
more than 10 Eurodollar Interest Periods shall be in effect at any
time.  Except as otherwise provided herein, each designation of an
interest rate with respect to the Facility A Notes or Facility B Notes
shall apply to all Facility A Notes and Facility B Notes ratably in
accordance with their respective outstanding principal balances.  If
any Bank assigns an interest in any of its Notes when any Eurodollar
Loan is outstanding with respect thereto, the assignee shall have its
ratable interest in such Eurodollar Loan.

     Section 4.  PAYMENTS OF PRINCIPAL AND INTEREST.

     4.1. REPAYMENT OF LOANS. (a) The Company will pay to the Agent
for the account of each Bank the principal of each Loan made by such
Bank on the dates provided in the respective Notes and herein and the
amount of each Reimbursement Obligation forthwith upon its incurrence. 
The amount of any Reimbursement Obligation may, if the applicable
conditions precedent specified in SECTION 7 (other than any Default
resulting solely from the nonpayment of such Reimbursement Obligation)
have been satisfied, be paid with the proceeds of Loans.

     (b)  Subject to SECTIONS 3.2 and 10.1, the Company shall pay the
outstanding principal amount of all Facility A Loans on the Facility A
Maturity Date and the outstanding principal amount of all Facility B
Loans on the Facility B Maturity Date.

     4.2. INTEREST.  (a) Subject to SECTION 12.8, the Company will pay
to the Agent for the account of each Bank interest on the unpaid
principal amount of each Loan made by such Bank for the period
commencing on the date of such Loan to but excluding the date such
Loan shall be paid in full, at the lesser of (1) the following rates
per annum:

     (A)  if such Loan is an Alternate Base Rate Loan, the Alternate
Base Rate PLUS the Applicable Margin for Alternate Base Rate Loans; or

     (B)  if such Loan is a Eurodollar Loan, the applicable Eurodollar
Rate PLUS the Applicable Margin for Eurodollar Loans; or

(2) the Highest Lawful Rate.

                                 -53-


     (b)  Notwithstanding any of the foregoing but subject to
SECTION 12.8, the Company will pay to the Agent for the account of
each Bank interest at the applicable Post-Default Rate on any
principal of any Loan made by such Bank and on any other amount
payable by the Company hereunder to or for the account of such Bank
(but, if such amount is interest, only to the extent legally
enforceable), which shall not be paid in full when due (whether at
stated maturity, by acceleration or otherwise), for the period
commencing on the due date thereof through and including the date the
same is paid in full.  

     (c)  Accrued interest shall be due and payable on the applicable
Interest Payment Dates, except that (1) accrued  interest payable at
the Post-Default Rate shall be due and payable from time to time on
demand of the Agent or the Required Banks (through the Agent), (2)
accrued interest on any amount converted from one Type of Loan to
another Type of Loan shall be paid on the amount so converted at the
time of such conversion, and (3) accrued interest on any Eurodollar
Loan paid or prepaid shall be due at the time of such payment or
prepayment.  

     Section 5.  PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS, ETC.

     5.1. PAYMENTS.  (a) Except to the extent otherwise provided
herein, all payments of principal of or interest on the Loans and
other amounts to be made by the Company hereunder and under the Notes
and the Security Documents shall be made in dollars, in immediately
available funds, to the Agent at its Principal Office (or in the case
of a successor Agent, at the principal office of such successor Agent
in the United States), not later than 11:00 a.m. on the date on which
such payment shall become due (each such payment made after such time
on such due date to be deemed to have been made on the next succeeding
Business Day).

     (b)  The Company shall, at the time of making each payment
hereunder or under any Note or any Security Document, specify to the
Agent the Loans or other amounts payable by the Company hereunder or
thereunder to which such payment is to be applied (and in the event
that it fails so to specify, such payment shall be applied as the
Agent may designate to the Loans or other amounts then due and
payable); PROVIDED that if no Loans are then due and payable or an
Event of Default has occurred and is continuing, the Agent may apply
such payment to the Obligations in such order as it may elect in its
sole discretion, but subject to the other terms and conditions of this
Agreement, including SECTION 5.2).  Each payment received by the Agent
hereunder or under any Note or any Security Document for the account
of a Bank shall be paid promptly to such Bank, in immediately
available funds for the account of such Bank's Applicable Lending
Office.

                                 -54-


     (c)  If the due date of any payment hereunder or under any Note
or Security Document falls on a day which is not a Business Day, the
due date for such payment (subject to the definition of Interest
Period) 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.

     5.2. PRO RATA TREATMENT.  Except to the extent otherwise provided
herein, (a) each borrowing from the Banks hereunder, each payment of
Commitment Fees and other fees and each termination or reduction of
the Commitments of the Banks under SECTION 2.3 shall be made PRO RATA
according to the Banks' respective Commitments, and (b) each payment
by the Company of principal of or interest on Loans of a particular
Type shall be made to the Agent for the account of the Banks PRO RATA
in accordance with the respective unpaid principal amounts of such
Loans held by the Banks (subject to SECTION 6.4).

     5.3. COMPUTATIONS.  Interest based on the Alternate Base Rate (to
the extent determined by reference to the Prime Rate), and fees
hereunder, will be computed on the basis of 365 (or 366) days and
actual days elapsed (including the first day but excluding the last
day) occurring in the period for which payable.  All other interest
shall be computed on the basis of a year of 360 days and actual days
elapsed (including the first day but excluding the last day) occurring
in the period for which payable, unless the effect of so computing
shall be to cause the rate of interest to exceed the Highest Lawful
Rate (in which event interest shall be calculated on the basis of the
actual number of days elapsed in a year composed of 365 or 366 days,
as the case may be).

     5.4. MINIMUM AND MAXIMUM AMOUNTS.  Except for prepayments made
pursuant to SECTION 3.2(b), each borrowing and repayment of principal
of Loans, each optional prepayment and each conversion of Type shall
be in an aggregate principal amount equal to $1,000,000, or an
integral multiple thereof (borrowings or prepayments of Loans of
different Types or, in the case of Eurodollar Loans, having different
Interest Periods at the same time hereunder, to be deemed separate
borrowings and prepayments for purposes of the foregoing, one for each
Type or Interest Period), and each termination or reduction of
Commitments shall be in an aggregate principal amount equal to
$5,000,000 or an integral multiple thereof.  Upon any mandatory
prepayment that would reduce Eurodollar Loans having the same Interest
Period to less than $1,000,000, such Loans shall automatically be
converted into Alternate Base Rate Loans.

     5.5. CERTAIN ACTIONS, NOTICES, ETC.  Notices to the Agent of any
termination or reduction of Commitments, prepayments of Loans and of
the duration of Interest Periods and Requests for Extension 

                                 -55-


of Credit shall be irrevocable and shall be effective only if received
by the Agent not later than 11:00 a.m. on the number of Business Days
prior to the date of the relevant termination, reduction, borrowing
and/or prepayment specified below:

                                        Number of Business
                                             Days Prior   
                                               Notice     

     Termination or reduction
     of Commitments                          10

     Borrowing or prepayment
     of or conversion into
     Alternate Base Rate Loans              same day

     Borrowing or prepayment
     of or conversion into or
     continuance of Eurodollar
     Loans                                    3

     Prepayments required
     pursuant to SECTION 3.2                  1

Each such notice of termination or reduction shall specify the amount
of the Commitment to be terminated or reduced.  Each such notice of
prepayment or Request for Extension of Credit shall specify the
amount, Class and Type of the Loans to be borrowed or prepaid (subject
to SECTIONS 3.2(a) and 5.4), the date of borrowing or prepayment
(which shall be a Business Day) and, in the case of Eurodollar Loans,
the duration of the Interest Period therefor (subject to the
definition of Interest Period).  Any such notice of conversion of a
Loan into a Loan of another Type shall identify such Loan (or portion
thereof) being converted and specify the Type of Loan into which such
Loan is being converted (subject to SECTION 5.4) and the date for
conversion (which shall be a Business Day) and, unless such Loan is
being converted into an Alternate Base Rate Loan, the duration
(subject to the definition of Interest Period) of the Interest Period
therefor which is to commence as of the last day of the then current
Interest Period therefor (or the date of conversion, if such Loan is
being converted from an Alternate Base Rate Loan).  Each such notice
of continuation of a Loan (or portion thereof) as the same Type of
Loan shall identify such Loan (or portion thereof) being continued
(subject to SECTION 5.4) and the duration (subject to the definition
of Interest Period) of the Interest Period therefor which is to
commence as of the last day of the then current Interest Period
therefor.  The Agent shall promptly notify the Banks of the contents
of each such notice or Request for Extension of Credit.  

                                 -56-


Notice of any prepayment having been given, the principal amount
specified in such notice, together with interest thereon to the date
of prepayment, shall be due and payable on such prepayment date.

     5.6. NON-RECEIPT OF FUNDS BY THE AGENT.  Unless the Agent shall
have been notified by a Bank prior to noon on the date on which such
Bank is to make payment to the Agent of the proceeds of a Loan to be
made by it hereunder or by the Company prior to the date on which the
Company is to make a payment to the Agent for the account of one or
more of the Banks, as the case may be (such Bank or the Company being
herein called the "PAYOR" and such payment being herein called the
"REQUIRED PAYMENT"), which notice shall be effective upon receipt,
that the Payor does not intend to make the Required Payment to the
Agent, the Agent may assume that the Required Payment has been made
and may, in reliance upon such assumption (but shall not be required
to), make the amount thereof available to the intended recipient on
the date that such Required Payment is to be made.  If the Payor is
the Company and the Company has not in fact made the Required Payment
to the Agent on or before such date, the recipient of such payment
shall, on demand, pay to the Agent the amount made available by the
Agent, together with interest thereon from the date such amount was so
made available by the Agent until the date the Agent recovers such
amount at a rate per annum equal to the Fed Funds Rate for the first
three days after demand and thereafter at the Fed Funds Rate plus 2%. 
If the Payor is a Bank and such Bank has not in fact made the Required
Payment to the Agent on or before such date, then such Bank shall pay
to the Agent the amount made available by the Agent on behalf of such
Bank, together with interest thereon from the date such amount was so
made available by the Agent until the Agent recovers such amount at a
rate per annum equal to the Fed Funds Rate for the first three days
and thereafter at the Fed Funds Rate plus 2%.

     5.7. SHARING OF PAYMENTS, ETC.  If a Bank or any participant of a
Bank shall obtain payment of any obligation to it under this
Agreement, through the exercise of any right of set-off, banker's
lien, counterclaim or similar right, or otherwise, then such Bank or
participant shall promptly purchase from the other Banks participa-
tions in the Loans made or other obligations held by the other Banks
in such amounts, and make such other adjustments from time to time as
shall be equitable to the end that all the Banks and participants
shall share the benefit of such payment (net of any expenses which may
be incurred by such Bank or its participant in obtaining or preserving
such benefit) PRO RATA in accordance with the unpaid principal and
interest then due to each of them.  To such end all the Banks and
their participants shall make appropriate adjustments among themselves
(by the resale of participations sold or otherwise) if such payment is
rescinded or 

                                 -57-


must otherwise be restored.  The Company agrees, to the fullest extent
it may effectively do so under applicable law, that any Person so
purchasing a participation in the Loans made or other obligations held
by other Banks may exercise all rights of set-off, bankers' lien,
counterclaim or similar rights with respect to such participation as
fully as if such Bank were a direct holder of Loans or other
obligations in the amount of such participation.  Nothing contained
herein shall require any Bank to exercise any such right or shall
affect the right of any Bank to exercise, and retain the benefits of
exercising, any such right with respect to any other indebtedness or
obligation of the Company.

     Section 6.  YIELD PROTECTION AND ILLEGALITY.  

     6.1. ADDITIONAL COSTS.

     (a)  Subject to SECTION 12.8, the Company shall pay to the Agent,
on demand for the account of such Bank, from time to time such amounts
as any Bank may reasonably determine to be necessary to compensate it
for any costs incurred by such Bank which such Bank reasonably
determines are attributable to its making or maintaining of any
Eurodollar Loan hereunder or its obligation to make or maintain any
such Loan hereunder, or any reduction in any amount receivable by such
Bank hereunder in respect of any of such Loans or such obligation
(such increases in costs and reductions in amounts receivable being
herein called "ADDITIONAL COSTS"), in each case resulting from any
Regulatory Change which:

          (1)  subjects such Bank (or makes it apparent that such Bank
is subject) to any tax (including any United States interest equali-
zation tax), levy, impost, duty, charge or fee (collectively,
"TAXES"), or any deduction or withholding for any Taxes on or from the
payment due under any Eurodollar Loan or other amounts due hereunder,
other than income and franchise taxes of the jurisdiction (or any
subdivision thereof) in which such Bank has an office or its
Applicable Lending Office; or

          (2)  changes the basis of taxation of any amounts payable to
such Bank under this Agreement or its Notes in respect of any of such
Loans, other than changes which affect taxes measured by or imposed on
the overall net income or franchise taxes of such Bank or of its
Applicable Lending Office for any of such Loans by the jurisdiction
(or any subdivision thereof) in which such Bank has an office or such
Applicable Lending Office; or

          (3)  imposes or modifies or increases or deems applicable
any reserve, special deposit or similar requirement (including any
such requirement imposed by the Board) relating to any extensions of
credit or other assets of, or any deposits with or other 

                                 -58-


liabilities of, such Bank or loans made by such Bank, or against any
other funds, obligations or other property owned or held by such Bank; or

          (4)  imposes any other condition affecting this Agreement
(or any of such extensions of credit or liabilities).

Each Bank will notify the Company through the Agent of any event
occurring after the date of this Agreement which will entitle such
Bank to compensation pursuant to this section as promptly as
practicable after it obtains knowledge thereof and determines to
request such compensation, and (if so requested by the Company through
the Agent) will designate a different available Applicable Lending
Office for the Eurodollar Loans of such Bank or take such other action
as the Company may reasonably request if such designation or action is
consistent with the internal policy of such Bank and legal and
regulatory restrictions, can be undertaken at no additional cost, will
avoid the need for, or reduce the amount of, such compensation and
will not, in the sole opinion of such Bank, be disadvantageous to such
Bank (PROVIDED that such Bank shall have no obligation so to designate
an Applicable Lending Office located in the United States of America). 
Each Bank will furnish the Company with a statement setting forth the
basis and amount of each request by such Bank for compensation under
this section, with each such statement to cover amounts accruing under
this section with respect to a period beginning not earlier than 120
days from the date thereof and using any reasonable averaging and
attribution methods.

     (b)  Without limiting the effect of the foregoing provisions of
this section, in the event that, by reason of any Regulatory Change,
any Bank either (1) 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 Bank which includes deposits by
reference to which the interest rate on Eurodollar Loans is determined
as provided in this Agreement or a category of extensions of credit or
other assets of such Bank which includes Eurodollar Loans or (2)
becomes subject to restrictions on the amount of such a category of
liabilities or assets which it may hold, then, if such Bank so elects
by notice to the Company (with a copy to the Agent), the obligation of
such Bank to make Eurodollar Loans hereunder shall be suspended until
the date such Regulatory Change ceases to be in effect (in which case
the provisions of SECTION 6.4 shall be applicable).

     (c)  Determinations and allocations by any Bank for purposes of
this section of the effect of any Regulatory Change on its costs of
maintaining its obligations to make Loans or of making or maintaining
Loans or on amounts receivable by it in respect of 

                                 -59-


Loans, and of the additional amounts required to compensate such Bank
in respect of any Additional Costs, shall be conclusive, absent
manifest error, and may be prepared using any reasonable averaging and
attribution methods.

     (d)  In the event any Bank shall seek compensation pursuant to
this SECTION 6.1, the Company may give notice to such Bank (with
copies to the Agent) that it wishes to seek one or more Eligible
Assignees (which may be one or more of the Banks) to purchase and
assume the Commitments, Loans, Notes and Letter of Credit Liabilities
of such Bank.  Each Bank requesting compensation pursuant to this
SECTION 6.1 agrees to sell its Commitments, Loans, Notes, Letter of
Credit Liabilities and interests in this Agreement and in the Letter
of Credit Agreement pursuant to SECTION 12.6 (without recourse,
representation or warranty except as provided in SECTION 12.6) to any
such Eligible Assignee for an amount equal to the sum of the
outstanding unpaid principal of and accrued interest on such Loans,
Notes and Letter of Credit Liabilities plus all other fees and amounts
(including any compensation claimed by such Bank under this
SECTION 6.1) owing to such Bank hereunder and under the Letter of
Credit Agreement calculated, in each case, to the date such
Commitments, Loans, Notes, Letter of Credit Liabilities and interests
are purchased, whereupon such Bank shall have no further Commitment or
other obligation to the Company hereunder or under any Note or under
the Letter of Credit Agreement.

     6.2. LIMITATION ON TYPES OF LOANS.  Anything herein to the
contrary notwithstanding, if, with respect to any Eurodollar Loans:

     (a)  the Agent determines (which determination shall be
conclusive absent manifest error) that quotations of interest rates
for the relevant deposits referred to in the definition of "Eurodollar
Base Rate" in SECTION 1.1 are not being provided in the relevant
amounts or for the relevant maturities for purposes of determining the
rate of interest for such Loans for Interest Periods therefor as
provided in this Agreement; or

     (b)  the Required Banks determine (which determination shall be
conclusive absent manifest error) and notify the Agent that the
relevant rates of interest referred to in the definition of "Eurodol-
lar Base Rate" in SECTION 1.1 upon the basis of which the rates of
interest for such Loans are to be determined do not accurately reflect
the cost to such Banks of making or maintaining such Loans for any
proposed Interest Periods therefor; or

     (c)  the Agent determines (which determination shall be
conclusive absent manifest error) that by reason of circumstances
affecting the Eurodollar interbank market generally, deposits in
dollars in the relevant Eurodollar interbank market are not being 

                                 -60-


offered for the applicable Interest Period and in an amount equal to
the amount of the Eurodollar Loan requested by the Company;

then the Agent shall promptly notify the Company and each Bank
thereof, and, so long as such condition remains in effect, the Banks
shall be under no obligation to make Eurodollar Loans (but shall
maintain until the end of the Interest Period then in effect the
Eurodollar Loans then outstanding).

     6.3. ILLEGALITY.  Notwithstanding any other provision of this
Agreement to the contrary, if by reason of (x) the adoption of any
applicable Legal Requirement or any change in any applicable Legal
Requirement or in the interpretation or administration thereof by any
Governmental Authority or compliance by any Bank with any request or
directive (whether or not having the force of law) of any central bank
or other Governmental Authority or (y) circumstances affecting the
relevant Eurodollar interbank market or the position of a Bank
therein, it shall at any time be unlawful or impracticable in the sole
discretion of a Bank for such Bank or its Applicable Lending Office to
(a) honor its obligation to permit the establishment of Eurodollar
Loans hereunder or (b) maintain Eurodollar Loans hereunder, then such
Bank through the Agent shall promptly notify the Company thereof and
the obligation of such Bank to establish or maintain Eurodollar Loans
hereunder shall be suspended until such time as such Bank may again
establish and maintain Eurodollar Loans, in which case the provisions
of SECTION 6.4 shall be applicable.  Before giving such notice
pursuant to this section, such Bank will designate a different
available Applicable Lending Office for the Eurodollar Loans of such
Bank or take such other action as the Company may reasonably request
if such designation or action is consistent with the internal policy
of such Bank and legal and regulatory restrictions, can be undertaken
at no additional cost, will avoid the need to suspend such Bank's
obligation to make Eurodollar Loans hereunder and will not, in the
sole opinion of such Bank, be disadvantageous to such Bank (PROVIDED
that such Bank shall have no obligation so to designate an Applicable
Lending Office located in the United States of America).  In the event
any Bank shall seek to invoke the benefits of this section, the
Company may give notice to such Bank (with copies to the Agent) that
it wishes to seek one or more Eligible Assignees (which may be one or
more of the Banks) to purchase and assume the Commitments, Loans,
Notes and Letter of Credit Liabilities of such Bank.  Each Bank
requesting to invoke the benefits of this SECTION 6.3 agrees to sell
its Commitments, Loans, Notes, Letter of Credit Liabilities and
interests in this Agreement and in the Letter of Credit Agreement
pursuant to SECTION 12.6 (without recourse, representation or warranty
except as provided in SECTION 12.6) to any such Eligible Assignee for
an amount equal to the sum of the outstanding unpaid principal of and

                                 -61-


accrued interest on such Loans, Notes and Letter of Credit Liabilities
plus all other fees and amounts owing to such Bank hereunder and under
the Letter of Credit Agreement calculated, in each case, to the date
such Commitments, Loans, Notes, Letter of Credit Liabilities and
interests are purchased, whereupon such Bank shall have no further
Commitment or other obligation to the Company hereunder or under any
Note or under the Letter of Credit Agreement.

     6.4. SUBSTITUTE ALTERNATE BASE RATE LOANS.  If the obligation of
any Bank to make or maintain Eurodollar Loans shall be suspended
pursuant to SECTION 6.1, 6.2 or 6.3, all Loans which would otherwise
be made by such Bank as Eurodollar Loans shall be made instead as
Alternate Base Rate Loans (and, if an event referred to in
SECTION 6.1(b) or 6.3 has occurred and such Bank so requests by notice
to the Company with a copy to the Agent, each Eurodollar Loan of such
Bank then outstanding shall be automatically converted into an
Alternate Base Rate Loan on the date specified by such Bank in such
notice) and, to the extent that such Loans are so made as (or
converted into) Alternate Base Rate Loans, all payments of principal
which would otherwise be applied to such Loans shall be applied
instead to such Alternate Base Rate Loans.

     6.5. COMPENSATION.  Subject to SECTION 12.8, the Company shall
pay to the Agent for the account of each Bank, within two Business
Days after demand therefor by such Bank through the Agent, such amount
or amounts as shall be sufficient (in the reasonable opinion of such
Bank) to compensate it for any loss, cost or expense incurred by it as
a result of:

     (a)  any payment, prepayment or conversion of a Eurodollar Loan
made by such Bank on a date other than the last day of an Interest
Period for such Loan; or

     (b)  any failure by the Company to borrow a Eurodollar Loan to be
made by such Bank on the date for such borrowing specified in the
relevant notice of borrowing under SECTION 5.5 or to convert an 
Alternate Base Rate Loan into a Eurodollar Loan on such date after
giving notice of such conversion or to continue a Eurodollar Loan
after giving notice of such continuance; or

     (c)  any cessation of the Eurodollar Rate to apply to any Loan or
any part thereof;

such compensation to include, without limitation, an amount equal to
the excess, if any, as reasonably determined by each Bank, of (1) its
cost of obtaining the funds for the Loan being paid, prepaid or
converted or not borrowed, converted or continued (assumed to be the
applicable Eurodollar Base Rate) for the period 

                                 -62-

from the date of such payment, prepayment or conversion or failure to
borrow convert or continue to the last day of the Interest Period for
such Loan (or, in the case of a failure to borrow, convert or continue
the Interest Period for the Loan which would have commenced on the
date of such failure to borrow convert or continue) over (2) the
amount of interest (as reasonably determined by such Bank) that would
be realized by such Bank in reemploying the funds so paid, prepaid or
converted or not borrowed, converted or continued for such period or
Interest Period, as the case may be.  Each determination of the amount
of such compensation by a Bank shall be conclusive and binding, absent
manifest error, and may be computed using any reasonable averaging and
attribution method.

     6.6. CAPITAL ADEQUACY.  If any Bank shall have determined that
the adoption after the date hereof or effectiveness after the date
hereof (regardless of whether previously announced) of any applicable
Legal Requirement or treaty regarding capital adequacy, or any change
after the date hereof in any existing or future Legal Requirement or
treaty regarding capital adequacy, or any change in the interpretation
or administration thereof after the date hereof by any Governmental
Authority or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable
Lending Office) with any request or directive after the date hereof
regarding capital adequacy (whether or not having the force of law) of
any such Governmental Authority or comparable agency has or would have
the effect of reducing the rate of return on the capital of such Bank
(or any holding company of which such Bank is a part) as a consequence
of its obligations hereunder and under or in respect of the Notes held
by it to a level below that which such Bank or holding company could
have achieved but for such adoption, change or compliance by an amount
deemed by such Bank to be material, then from time to time, upon
demand by such Bank (with a copy to the Agent), the Company (subject
to SECTION 12.8) shall pay to such Bank such additional amount or
amounts as will compensate such Bank or holding company for such
reduction.  The certificate of any Bank setting forth such amount or
amounts as shall be necessary to compensate it and the basis therefor
shall cover amounts accruing under this section with respect to a
period beginning not earlier than 120 days from the date thereof and
shall be conclusive and binding, absent manifest error.  The Company
shall pay the amount shown as due on any such certificate upon
delivery of such certificate.  In preparing such certificate, a Bank
may employ such assumptions and allocations of costs and expenses as
it shall in good faith deem reasonable and may use any reasonable
averaging and attribution method.  In the event any Bank shall seek
compensation pursuant to this section, the Company may give notice to
such Bank (with copies to the Agent) that it wishes to seek one or
more Eligible Assignees (which may be 

                                 -63-


one or more of the Banks) to purchase and assume the Commitments,
Loans, Notes and Letter of Credit Liabilities of such Bank.  Each Bank
requesting compensation pursuant to this section agrees to sell its
Commitments, Loans, Notes, Letter of Credit Liabilities and interests
in this Agreement and in the Letter of Credit Agreement pursuant to
SECTION 12.6 (without recourse, representation or warranty except as
provided in SECTION 12.6) to any such Eligible Assignee for an amount
equal to the sum of the outstanding unpaid principal of and accrued
interest on such Loans, Notes and Letter of Credit Liabilities plus
all other fees and amounts (including any compensation claimed by such
Bank under this section owing to such Bank hereunder and under the
Letter of Credit Agreement calculated, in each case, to the date such
Commitments, Loans, Notes, Letter of Credit Liabilities and interests
are purchased, whereupon such Bank shall have no further Commitment or
other obligation to the Company hereunder or under any Note or the
Letter of Credit Agreement.

     Section 7.  CONDITIONS PRECEDENT.

     7.1. CLOSING CONDITIONS.  The effectiveness of this Agreement is

(2) any other jurisdiction in which the nature of the business
conducted by it makes such qualification necessary or advisable,
unless (for purposes only of this CLAUSE (2)) the failure to be so
qualified or in good standing would not individually or in the
aggregate have a material adverse effect on the business, financial
condition or results of operations of the Combined Group taken as a
whole.

     8.2. INFORMATION.

     (a)  (1)  The most recent consolidated balance sheet of the
Company and its Subsidiaries and the related consolidated statements

Agreement (which financial statements are dated December 31, 1993), or

Legal Requirement (including any securities law, rule or regulation)
applicable to the Company or any of its Subsidiaries or (except for
the Liens required or permitted by this Agreement and the Security
Documents) result in the creation or imposition of any Lien upon any
of the revenues or property of the Company or any of its Subsidiaries. 
Such execution, delivery, consummation and compliance do not and will

bound or to which it is subject, or constitute a default under any
such agreement or instrument.

to the enforcement of creditors' rights generally and by general
equitable principles.

all United States federal income tax returns and all other material

the Agent prior to the date hereof, the Company and its Subsidiaries,
and the plants and sites of each, have complied with all Applicable
Environmental Laws, except, in any such case, where such failure to so

limiting the generality of the preceding sentence, neither the Company
nor any of its Subsidiaries has received notice of or has actual
knowledge of any actual or claimed or asserted failure so to comply
with Applicable Environmental Laws or of any other Environmental Claim
which alone or together with all other such failures or Environmental
Claims is material and would result in a Material Adverse Change. 
Except as disclosed in writing to the Agent prior to the date hereof,
neither the Company nor any of its Subsidiaries nor their plants or

Environmental Laws or any other applicable Legal Requirement, or in a
manner which would result in an Environmental Claim except where such
noncompliance or liability or Environmental Claim would not result in
a Material Adverse Change.  The representation and warranty contained
in this section is based in its entirety upon (a) current

disseminated and are used by Governmental Authorities charged with the
enforcement of the Applicable Environmental Laws or which apply to the

deliver and perform the Security Documents with respect to all such
properties and to convey, assign and mortgage the same, without the
necessity of any consent, approval or other action of any kind of or
by any other Person, failure to obtain which could cause a Material
Adverse Change, and such execution, delivery and performance will not
result in the breach of or constitute a default under any agreement,
instrument, judgment, license, order or permit to which the Company is
a party or by which the Company  or any of its property may be bound,
which together with all other such breaches and defaults could cause a
Material Adverse Change.

purchase and sales contracts, and other agreements comprising or
relating to any of such properties are valid and subsisting and in
full force and effect, except for those leases, estates, contracts,

Properties in the Most Recent Engineering Report furnished to the
Banks, taken as a whole.

     (e)  All rights, permits, easements, servitudes and
rights-of-way, failure to have or maintain which would materially
interfere with the development, maintenance and operation of such
properties so as to cause a Material Adverse Change, have been
obtained by the Company and are in full force and effect.

     (f)  Each of the Security Documents creates or will create, when
executed and delivered, a valid Lien upon the Property therein

liabilities and hazards and by such methods as customarily maintained
by other companies operating similar businesses and, together with
each delivery of financial statements required by SECTION 9.1(b) will
deliver to the Agent for each Bank an Officer's Certificate specifying
the details of such insurance in effect.  Upon the request of the
Agent or any Bank, the Company shall promptly deliver to the Agent one
or more current certificates of the insurer or insurers providing the
insurance required by this SECTION 9.5 to the effect that such
insurance may

interests in the Special Subsidiary; PROVIDED FURTHER that the amount
of such Investment shall be included in any subsequent computations of
Restricted Payments and of Consolidated Net Earnings Available for
Restricted Payments and Restricted Investments under this Section

of pursuant to SECTION 9.7(c)(2) or (3)) to any Person except that 

          (1)  any wholly owned Restricted Subsidiary may merge with
the Company (PROVIDED that the Company shall be the continuing or
surviving corporation) or with any one or more other wholly owned
Restricted Subsidiaries;

          (2)  any Restricted Subsidiary may sell, exchange, transfer
or otherwise dispose of any of its assets to the Company or to a
wholly owned Restricted Subsidiary;

          (3)  any Restricted Subsidiary may sell, exchange, transfer
or otherwise dispose of all or substantially all of its assets subject
to the conditions and provisions specified in SECTIONS 9.7(c)(2) and
(3);

          (4)  any Restricted Subsidiary may merge into or consolidate
with any Person which does not thereupon become a Restricted
Subsidiary, subject to the conditions and provisions specified in
SECTION 9.7(d) with respect to a sale or other disposition of the
stock of such Restricted Subsidiary;

          (5)  any Restricted Subsidiary may permit any Person to be
merged into such Restricted Subsidiary or may consolidate with or
merge into a Person which thereupon becomes a Restricted Subsidiary;
PROVIDED that immediately after any such merger or consolidation, no
Default shall have occurred and be continuing;

          (6)  the Company may permit any Person to be merged into the
Company (such that the Company shall be the continuing or surviving
corporation); and

          (7)  the Company may permit any corporation to consolidate
with the Company and the Company may merge into or otherwise dispose
of its assets as an entirety or substantially as an entirety to any
solvent corporation organized under the laws of the United States of
America or any state thereof and having at least 80% of its
consolidated assets located in the United States of America and Canada
which expressly assumes in writing the due and punctual performance of
the obligations of the Company under the Credit Documents, to the same
extent as if such successor or transferee corporation had originally
executed the Credit Documents in the place of the Company (it being
agreed that such assumption shall, upon the request of any Bank and at
the expense of such successor or transferee corporation, be evidenced
by the exchange of such Note for another Note executed by such
successor or transferee corporation, with such changes in phraseology
and form 

                                 -88-


as may be appropriate but in substance of like terms as the Note
surrendered for such exchange and of like unpaid principal amount, and
that each Note executed pursuant to this Agreement after such assump-
tion shall be executed by and in the name of such successor or
transferee corporation);

PROVIDED that for purposes of SECTIONS 9.7(e)(6) and (7) immediately
after such merger, consolidation, sale or other disposition, and after
giving effect thereto, (x) such successor or transferee Person could
incur at least $1.00 of additional Funded Debt without violation of
SECTION 9.7(b)(3) and (y) no Default shall have occurred and be
continuing.  As soon as practicable, and in any event at least 75 days
prior to the proposed consummation date of any merger, consolidation,
sale or other disposition described in SECTION 9.7(e)(7), the Company
shall give written notice thereof to each Bank describing in
reasonable detail the proposed transaction, the date on which it is
proposed to be consummated and the identity, jurisdiction of
organization, and geographic composition of assets of the proposed
successor or transferee corporation.  No disposition by the Company of
its assets as an entirety or substantially as an entirety under
SECTION 9.7(e)(7) shall release the Company as the maker of the Notes
from its liability as obligor thereon.

     (f)  SALE AND LEASEBACK.  Enter into any Sale and Leaseback
Transaction unless:

          (1)  immediately after giving effect thereto and to the
application of any sales proceeds received in connection therewith,
Special Debt shall not exceed 10% of the Consolidated Net Tangible
Assets; or

          (2)  the net sales proceeds received by the Company or a
Restricted Subsidiary in respect of the assets sold pursuant to such
Sale and Leaseback Transaction are greater than or equal to the fair
market value of the assets sold (which determination shall be based
upon a written opinion (the cost of which shall be borne exclusively
by the Company) as to valuation from an independent valuation expert
selected by the Company) and such proceeds are concurrently applied to
(A) the purchase, acquisition, development or construction of assets
having a value at least equal to such net proceeds, and to be used in
the Company's or such Restricted Subsidiary's business; PROVIDED that
no Liens shall at any time exist on such assets which secure any Debt
except as permitted by SECTION 9.7(a)(13); (B) the prepayment in
accordance with this Agreement of any aggregate principal amount of
all the Obligations (plus accrued interest and premium, if any) at
least equal to the amount of such net proceeds; or (C) the payment of
other Funded Debt (other than Funded Debt subordinate in right of
payment to the

                                 -89-


Obligations) in an aggregate principal amount at least equal to the
amount of such net sales proceeds; or

          (3)  the Sale and Leaseback Transaction involves the sale of
assets by the Company to a wholly owned Restricted Subsidiary or by a
Restricted Subsidiary to the Company or to another wholly owned
Restricted Subsidiary; PROVIDED that if the Company is the seller
under any such Sale and Leaseback Transaction, its lease obligations
thereunder shall be subordinated to the Funded Debt represented by the
Notes upon terms set forth on SCHEDULE V.

     (g)  INVESTMENTS IN THE SPECIAL SUBSIDIARY.  Directly or
indirectly make an Investment in the Special Subsidiary after
March 31, 1990, unless (1) the aggregate amount of all other
Investments in the Special Subsidiary made, directly or indirectly, by
the Company and the Restricted Subsidiaries after March 31, 1990 shall
not exceed the aggregate amount of cash distributions received by the
Company and the Restricted Subsidiaries from the Special Subsidiary
after March 31, 1990 or (2) in the opinion of the Board of Directors
of the Company, the Investment would not impair the ability of the
Company to make when due any payment (including any prepayment
required by SECTION 3.2(b)) of principal of or interest on the Notes.

     (h)  TRANSACTIONS WITH AFFILIATES.  Directly or indirectly
purchase, acquire or lease any property from, or sell, transfer or
lease any property to, or otherwise deal with, in the ordinary course
of business or otherwise, (1) any Affiliate (except any employee
compensation benefit plan or any Restricted Subsidiary) or (2) any
Person (other than a Restricted Subsidiary) in which an Affiliate or
the Company (directly or indirectly) owns, beneficially or of record,
5% or more of the outstanding voting stock or similar equity interest,
except that (A) any Affiliate may be a director, officer or employee
of the Company or any Restricted Subsidiary and may be paid reasonable
compensation in connection therewith and (B) subject to applicable
fiduciary standards with respect to the Special Subsidiary, acts and
transactions that would otherwise be prohibited by this Subsection may
be performed or engaged in if upon terms not less favorable to the
Company or any Restricted Subsidiary than if no relationship described
in CLAUSES (1) and (2) above existed.

     (i)  TAX CONSOLIDATION.  Except for the Tax Allocation
Agreements, the Company will not, and will not permit any of its
Subsidiaries to, file or consent to the filing of any consolidated
income tax return with any Person unless such other Person shall have
agreed in writing with the Company that the Company's or such
Subsidiary's liability with respect to taxes as a result of the filing
of any such consolidated income tax return with such Person 

                                 -90-


shall not be materially greater, nor the receipt of any tax benefits
materially less, than they would have been had the Company and its
Subsidiaries continued to file a consolidated income tax return with
the Company as the parent corporation.

     9.8. ISSUANCE OF STOCK BY RESTRICTED SUBSIDIARIES.  The Company
covenants that it will not permit any Restricted Subsidiary (either
directly or indirectly, by the issuance of rights or options for, or
securities convertible into, such shares) to issue, sell or otherwise
dispose of any shares of any authorized but unissued or treasury class
of such Restricted Subsidiary's stock (other than directors'
qualifying shares) except to the Company or another Restricted
Subsidiary.

     9.9. COVERAGE RATIOS.  As of the end of each fiscal quarter of
the Company, and each delivery of a Required Reserve Report or
Optional Reserve Report, the Company shall be in compliance with all
Required Ratios (except for any noncompliance resulting solely from an
Engineering Shortfall, and then only prior to the cure thereof
permitted by SECTION 10.1(e)).

     9.10. PREPAYMENT OF JUNIOR SECURITIES.  Without the prior
written consent of the Required Banks, the Company shall not prepay
(or deposit any property to defease) any indebtedness consisting of
Junior Securities before the payment in full of all indebtedness under
the Credit Documents.

     Section 10.  DEFAULTS.

in any agreement under which any such obligation is created (or if any
other event thereunder or under any such agreement shall occur and be
continuing) and the effect of such failure or other event is to cause,
or to permit the holder or holders of such obligation (or a trustee on
behalf of such holder or holders) to cause, such obligation to become
due prior to any stated maturity, or any member of the Combined Group
shall fail to pay any Guaranty relating to Debt for borrowed money in
accordance with its terms, PROVIDED that the aggregate amount of all
obligations as to which such a payment default shall occur and be
continuing or such a failure or other event causing or permitting
acceleration shall occur and be continuing shall exceed $10,000,000;
or

     (c)  any representation or warranty by the Company or any of its

Agent or the Banks in connection herewith shall prove to have been
false or misleading in any material respect as of the date as of which

Independent Engineering Report and related Coverage Report; or

     (f)  the Company shall default in the performance of any of its

                                 -92-


whether now or hereafter in effect (herein called the "BANKRUPTCY

voluntary liquidation and dissolution of a Restricted Subsidiary)
relating to any member of the Combined Group under the Bankruptcy Law

                                 -93-


discharge), or a stay of execution thereof shall not be procured,

diminution of value equaling or exceeding the greater of (i) any
substantial portion of the properties of Trend and its Subsidiaries
taken as a whole, or (ii) a loan value (based on the Most Recent
Engineering Report) which equals or exceeds $5,000,000 as of the most
recent determination thereof; or

     (p)  the Company or any ERISA Affiliate shall fail to pay when

terminated (whereupon the Commitments shall be terminated); and (b)
declare the principal amount then outstanding of and the accrued
interest on the Loans and all fees and all other amounts payable
hereunder and under the Notes to be forthwith due and payable, where-
upon such amounts shall be and become immediately due and payable,
without notice (including notice of acceleration and notice of intent
to accelerate), presentment, demand, protest or other formalities of
any kind, all of which are hereby expressly WAIVED by the Company;
PROVIDED that in the case of the occurrence of an Event of Default
with respect to the Company referred to in SECTION 10.1(g) through
(l), the Commitments shall be automatically terminated and the prin-
cipal amount then outstanding of and the accrued interest on the Loans
and fees and all other amounts payable hereunder and under the Notes
shall be and become automatically and immediately due and payable,
without notice (including notice of intent to accelerate and notice of
acceleration) and without presentment, demand, protest or other for-
malities of any kind, all of which are hereby expressly WAIVED by the
Company; (II) each Bank may exercise its rights of offset against each
account and all other property of the Company in the possession of
such Bank, which right is hereby granted by the Company to the Banks; 
                                 -95-


and (III) the Agent and each Bank may exercise any and all other
rights pursuant to the Credit Documents, at law and in equity. 

     Section 11.  THE AGENT.

     11.1.     APPOINTMENT, POWERS AND IMMUNITIES.  Each Bank hereby
irrevocably appoints and authorizes the Agent to act as its Agent
under the Credit Documents with such powers as are specifically
delegated to the Agent by the terms thereof, together with such other
powers as are reasonably incidental thereto, including the execution
and delivery of the First Amendment to Deed of Trust.  The Agent
(which term as used in this section shall include reference to its
Affiliates and its own and its Affiliates' officers, directors,
employees and agents) shall (a) have no duties or responsibilities
except those expressly set forth in the Credit Documents, and shall
not by reason of any Credit Document be a trustee or fiduciary for any
Bank; (b) not be responsible to any Bank for any recitals, statements,
representations or warranties contained in any Credit Document, or in
any certificate or other document referred to or provided for in, or
received by any of them under, any Credit Document, or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of
any Credit Document or any other document referred to or provided for
therein or any property covered thereby or for any failure by the
Company or any other Person to perform any of its obligations
thereunder; (c) not be required to initiate or conduct any litigation
or collection proceedings hereunder or under any Credit Document
except to the extent requested by the Required Banks (and SECTION 11.7
shall apply), and (d) not be responsible for any action taken or
omitted to be taken by it under any Credit Document or any other
document or instrument referred to or provided for therein or in
connection therewith, including pursuant to its own negligence, except
for its own gross negligence or willful misconduct.  The Agent may
employ agents and attorneys-in-fact and shall not be responsible for
the negligence or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care.  In any foreclosure proceeding
concerning any collateral for the Notes or other obligations of the
Company hereunder, each holder of a Note or other obligations of the
Company hereunder if bidding for its own account or for its own
account and the accounts of other Banks is prohibited from including
in the amount of its bid an amount to be applied as a credit against
its Notes or the Notes of the other Banks; instead, such holder must
bid in cash only.  

     11.2.     RELIANCE BY AGENT.  The Agent shall be entitled to rely
upon any certification, notice or other communication (including any
thereof by telephone, telex, telegram or cable) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of
the proper Person or Persons, and upon 

                                 -96-


advice and statements of legal counsel (which may be counsel for the
Company), independent accountants and other experts selected by the
Agent.  As to any matters not expressly provided for by any Credit
Document, the Agent shall in all cases be fully protected in acting,
or in refraining from acting, hereunder and thereunder in accordance
with instructions of the Required Banks, and any action taken or
failure to act pursuant thereto shall be binding on all of the Banks. 
Pursuant to instructions of all Banks or the Required Banks, as
appropriate, the Agent shall have the authority to execute releases of
the Security Documents on behalf of the Banks without the joinder of
any Bank.

     11.3.     DEFAULTS.  The Agent shall not be deemed to have know-
ledge of the occurrence of a Default (other than the non-payment of
principal of or interest on Loans) unless it has received notice from
a Bank or the Company specifying such Default and stating that such
notice is a "Notice of Default".  In the event that the Agent receives
such a notice of the occurrence of a Default, the Agent shall give
prompt notice thereof to the Banks (and shall give each Bank prompt
notice of each such non-payment).  The Agent shall (subject to
SECTIONS 11.7 and 12.5) take such action with respect to such Default
as shall be directed by all Banks or the Required Banks, as
appropriate, and within its rights under the Credit Documents and at
law or in equity; PROVIDED that, unless and until the Agent shall have
received such directions, the Agent may (but shall not be obligated
to) take such action, or refrain from taking such action, permitted
hereby with respect to such Default as it shall deem advisable in the
best interests of the Banks and within its rights under the Credit
Documents, at law or in equity.

     11.4.     RIGHTS AS A BANK.  With respect to their Commitments
and Loans, TCB and NationsBank in their capacities as Banks hereunder
shall have the same rights and powers hereunder as any other Bank and
may exercise the same as though they were not acting as the Agent or
the Co-Agents, and the term "Bank" or "Banks" shall, unless the
context otherwise indicates, include the Agent and the Co-Agents in
their individual capacity.  The Agent and the Co-Agents may (without
having to account therefor to any Bank) accept deposits from, lend
money to and generally engage in any kind of banking, trust, letter of
credit, agency or other business with the Company (and any of its
Affiliates) as if they were not acting as the Agent and the Co-Agents,
and the Agent and the Co-Agents may accept fees and other considera-
tion from the Company and its Affiliates (in addition to the fees
heretofore agreed to between the Company and the Agent or the
Co-Agents) for services in connection with this Agreement or otherwise
without having to account for the same to the Banks.

                                 -97-


     11.5.     INDEMNIFICATION.  THE BANKS AGREE TO INDEMNIFY THE
AGENT (TO THE EXTENT NOT REIMBURSED UNDER SECTION 12.3 OR 12.4, BUT
WITHOUT LIMITING THE OBLIGATIONS OF THE COMPANY UNDER SAID
SECTIONS 12.3 AND 12.4), RATABLY IN ACCORDANCE WITH THEIR RESPECTIVE
COMMITMENTS, FOR ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR
DISBURSEMENTS OF ANY KIND AND NATURE WHATSOEVER (INCLUDING THE
CONSEQUENCES OF THE NEGLIGENCE OF THE AGENT) WHICH MAY BE IMPOSED ON,
INCURRED BY OR ASSERTED AGAINST THE AGENT IN ANY WAY RELATING TO OR
ARISING OUT OF ANY CREDIT DOCUMENT (AS DEFINED HEREIN) OR ANY OTHER
DOCUMENTS CONTEMPLATED BY OR REFERRED TO THEREIN OR THE TRANSACTIONS
CONTEMPLATED THEREBY (INCLUDING THE COSTS AND EXPENSES WHICH THE
COMPANY IS OBLIGATED TO PAY UNDER SECTIONS 12.3 AND 12.4 BUT
EXCLUDING, UNLESS A DEFAULT HAS OCCURRED AND IS CONTINUING, NORMAL
ADMINISTRATIVE COSTS AND EXPENSES INCIDENT TO THE PERFORMANCE OF ITS
AGENCY DUTIES HEREUNDER) OR THE ENFORCEMENT OF ANY OF THE TERMS HEREOF
OR THEREOF OR OF ANY SUCH OTHER DOCUMENTS, INCLUDING THE NEGLIGENCE OF
THE AGENT; PROVIDED THAT NO BANK SHALL BE LIABLE FOR ANY OF THE
FOREGOING TO THE EXTENT THEY ARISE FROM THE GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT OF THE PARTY TO BE INDEMNIFIED.  The obligations of
the Banks under this SECTION 11.5 shall survive the termination of
this Agreement.

     11.6.     NON-RELIANCE ON THE AGENT AND OTHER BANKS.  Each Bank
agrees that it has received current financial information with respect
to the Company and that it has, independently and without reliance on
the Agent, the Co-Agents or any other Bank and based on such documents
and information as it has deemed appropriate, made its own credit
analysis of the Company and decision to enter into this Agreement and
that it will, independently and without reliance upon the Agent, the
Co-Agents or any other Bank, and based on such documents and
information as it shall deem appropriate at the time, continue to make
its own analysis and decisions in taking or not taking action under
the Credit Documents.  The Agent and the Co-Agents shall not be
required to keep themselves informed as to the performance or
observance by the Company of any Credit Document or any other document
referred to or provided for therein or to inspect the property or
books of the Company or any other Person.  Except for notices, reports
and other documents and information expressly required to be furnished
to the Banks by the Agent and the Co-Agents under the Credit
Documents, the Agent and the Co-Agents shall not have any duty or
responsibility to provide any Bank with any credit or other
information concerning the affairs, financial condition or business of
the Company (or any of its Affiliates) which may come into the
possession of the Agent or either Co-Agent.

     11.7.     FAILURE TO ACT.  Except for action expressly required
of the Agent under the Credit Documents, the Agent shall 

                                 -98-


in all cases be fully justified in failing or refusing to act
hereunder and thereunder unless it shall receive further assurances to
its satisfaction by the Banks of their indemnification obligations
under SECTION 11.5 against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such
action.

     11.8.     RESIGNATION OR REMOVAL OF THE AGENT.  Subject to the
appointment and acceptance of a successor Agent as provided below, the
Agent may resign at any time by giving notice thereof to the Banks and
the Company, and the Agent may be removed at any time with or without
cause by the Required Banks.  Upon any such resignation or removal,
the Required Banks shall have the right to appoint a successor Agent. 
If no successor Agent shall have been so appointed by the Required
Banks and shall have accepted such appointment within 30 days after
the retiring Agent's giving of notice of resignation or the Required
Banks' removal of the retiring Agent, then the retiring Agent may, on
behalf of the Banks, appoint a successor Agent.  Any successor Agent
shall be a bank which has an office in the United States and a
combined capital and surplus of at least $250,000,000 and with its
deposits insured by the FDIC.  Upon the acceptance of any appointment
as the Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. 
Such successor Agent shall promptly specify its Principal Office
referred to in SECTIONS 3.1 and 5.1 by notice to the Company.  After
any retiring Agent's resignation or removal hereunder as the Agent,
the provisions of this SECTION 11 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it
while it was acting as the Agent.

     Section 12.  MISCELLANEOUS.

     12.1.     WAIVER.  No waiver of any Default shall be a waiver of
any other Default.  No failure on the part of the Agent or any Bank to
exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under any Credit Document
shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege thereunder preclude any
other or further exercise thereof or the exercise of any other right,
power or privilege.  The remedies provided in the Credit Documents are
cumulative and not exclusive of any remedies provided by law or in
equity.

    12.2. NOTICES.  All notices and other communications provided for
herein (including any modifications of, or waivers or consents under,

     12.3.     EXPENSES, ETC.  Whether or not any Loan is ever made,
the Company shall pay or reimburse on demand each of the Banks, the
Agent and the Co-Agents for paying:  (a) the reasonable fees and
expenses of Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P., special
counsel to the Agent, and of local counsel to the Agent in the States
of Louisiana, Oklahoma and Alabama in connection with (1) the
preparation, execution and delivery of the Credit Documents (including
the exhibits and schedules hereto), the making of the Loans hereunder
and (2) any modification, supplement or waiver of any of the terms of
any Credit Document; (b) all reasonable out-of-pocket costs and expen-
ses of the Banks, the Agent and the Co-Agents (including costs of
preparing an Independent Engineering Report and reasonable counsels'
fees) in connection with any Event of Default under or the enforcement
of any Credit Document; (c) all transfer, stamp, documentary or other
similar taxes, assessments or charges levied by any governmental or
revenue authority in respect of any Credit Document or any other

assessments and other charges incurred in connection with any filing,
registration, recording or perfection of any security interest
contemplated by this Agreement, any Security Document or any document
referred to herein or therein; and (e) reasonable expenses of due
diligence and syndication, and mutually agreed advertising and
marketing costs.

     12.4.     INDEMNIFICATION.  THE COMPANY SHALL INDEMNIFY THE
AGENT, THE CO-AGENTS, THE BANKS, AND EACH AFFILIATE THEREOF AND THEIR
RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AGENTS AND COUNSEL FROM,
AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES,
LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES TO WHICH ANY OF THEM
MAY BECOME SUBJECT, REGARDLESS OF AND INCLUDING LOSSES, LIABILITIES,
COSTS, EXPENSES, CLAIMS AND DAMAGES ARISING FROM THE NEGLIGENCE OF THE
AGENT OR THE CO-AGENTS OR THE BANKS OR ANY OTHER INDEMNITEE, INSOFAR
AS SUCH LOSSES, LIABILITIES, COSTS, EXPENSES, CLAIMS OR DAMAGES ARISE
OUT OF OR RESULT FROM ANY (A) ACTUAL OR PROPOSED USE BY THE COMPANY OF
THE PROCEEDS OF ANY EXTENSION OF CREDIT BY ANY BANK HEREUNDER;
(B) BREACH BY THE COMPANY OF ANY CREDIT DOCUMENT (AS DEFINED HEREIN);
(C) VIOLATION BY THE COMPANY 

                                 -100-


OR ANY OF ITS SUBSIDIARIES OF ANY LEGAL REQUIREMENT INCLUDING, WITHOUT
LIMITATION, APPLICABLE ENVIRONMENTAL LAWS; (D) ANY BANK'S OR THE
AGENT'S OR ANY CO-AGENT'S BEING DEEMED AN OWNER OR OPERATOR OF ANY
ASSETS OF THE COMPANY OR ITS SUBSIDIARIES BY A COURT OR OTHER
REGULATORY OR ADMINISTRATIVE AGENCY OR TRIBUNAL IN CIRCUMSTANCES IN
WHICH NEITHER THE AGENT, EITHER CO-AGENT NOR ANY OF THE BANKS IS
GENERALLY OPERATING OR GENERALLY EXERCISING CONTROL OVER SUCH ASSETS,
TO THE EXTENT SUCH LOSSES, LIABILITIES, CLAIMS OR DAMAGES ARISE OUT OF
OR RESULT FROM ANY LEGAL REQUIREMENT INCLUDING, WITHOUT LIMITATION,
APPLICABLE ENVIRONMENTAL LAWS PERTAINING TO THE CONDITION OF SUCH
ASSETS, (E) ENVIRONMENTAL CLAIMS OR (F) ANY INVESTIGATION, LITIGATION
OR OTHER PROCEEDING (INCLUDING ANY THREATENED INVESTIGATION OR
PROCEEDING) RELATING TO ANY OF THE FOREGOING, and the Company shall
reimburse the Agent, each Co-Agent, each Bank, and each Affiliate
thereof and their respective directors, officers, employees, agents
and counsel, upon demand, for any expenses (including legal fees)
incurred in connection with any such investigation or proceeding; but
excluding any such losses, liabilities, claims, damages, costs or
expenses incurred by a Person or any Affiliate thereof or their
respective directors, officers, employees, agents or counsel by reason
of the gross negligence or willful misconduct of such Person,
Affiliate, director, officer, employee, agent or counsel.  The
obligation of the Company to provide indemnification under this
section for fees and expenses of counsel shall be limited to the fees
and expenses of one counsel in each jurisdiction representing all of
the Persons entitled to such indemnification, except to the extent
that, in the reasonable judgment of any such indemnified Person, the
existence of actual or potential conflicts of interest make
representation of all of such indemnified Persons by the same counsel
inappropriate; in such a case, the Person exercising such judgment
shall be indemnified for the reasonable fees and expenses of its
separate counsel to the extent provided in this Section without giving
effect to the first clause of this sentence.  Nothing in this
SECTION 12.4 is intended to limit the obligations of the Company under
any other provision of this Agreement.

     12.5.     AMENDMENTS, ETC.  No amendment or waiver of any
provision of any Credit Document, nor any consent to any departure by
the Company therefrom, shall in any event be effective unless the same
shall be agreed or consented to by the Required Banks and the Company,
and each such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given;
PROVIDED that no amendment, waiver or consent shall, unless in writing
and signed by each Bank affected thereby, (a) increase any Commitment
of any of the Banks or subject the Banks to any additional obliga-
tions; (b) reduce the principal of, or interest on, any Loan, fee or
other sum to be paid under any Credit Document; (c) postpone any
scheduled date fixed for any payment of 

                                 -101-


principal of, or interest on, any Loan, fee or other sum to be paid
under any Credit Document; (d) change the percentage of any of the
Commitments, or of the aggregate unpaid principal amount of any of the
Loans, or the number of Banks which shall be required for the Banks or
any of them to take any action under this Agreement; (e) change any
provision contained in SECTIONS 2.5, 5.2, 5.7, 6, 12.3 or 12.4 or this
SECTION 12.5, or in the definition of "Required Ratios", or (f) except
as provided in the Credit Documents, release any material part of the
security for the obligations of the Company under any Credit Document. 
Except as permitted by the Mortgages, Mortgaged Properties cannot be
sold for consideration other than cash without the approval of all
Banks.  Anything in this SECTION 12.5 to the contrary, no amendment,
waiver or consent shall be made with respect to SECTION 11 without the
consent of the Agent and the Co-Agents.

     12.6.     SUCCESSORS AND ASSIGNS.  (a)  This Agreement shall be
binding upon and inure to the benefit of the Company, the Agent, the
Co-Agents and the Banks and their respective successors and assigns. 
The Company may not assign or transfer any of its rights or
obligations hereunder without the prior written consent of all of the
Banks.

     (b)  Each Bank may sell participations to any Person in all or
part of any Loan, or all or part of its Notes or Commitments, in which
event, without limiting the foregoing, the provisions of SECTION 6
shall inure to the benefit of each purchaser of a participation and
the PRO RATA treatment of payments, as described in SECTION 5.2, shall
be determined as if such Bank had not sold such participation.  In the
event any Bank shall sell any participation, (1) the Company, the
Agent, the Co-Agents and the other Banks shall continue to deal solely
and directly with such selling Bank in connection with such selling
Bank's rights and obligations under the Credit Documents (including
the Notes held by such selling Bank); (2) such Bank shall retain the
sole right and responsibility to enforce the obligations of the
Company relating to the Loans, including the right to approve any
amendment, modification or waiver of any provision of this Agreement
other than amendments, modifications or waivers with respect to (A)
any fees payable hereunder to the Banks, (B) the amount of principal
or the rate of interest payable on, or the dates fixed for the
scheduled repayment of principal of, the Loans and other sums to be
paid to the Banks hereunder, and (C) the release or termination of all
or substantially all of the security for the Loans, and (3) the
Company agrees, to the fullest extent it may effectively do so under
applicable law, that any participant of a Bank may exercise all rights
of set-off, bankers' lien, counterclaim or similar rights with respect
to such participation as fully as if such 

                                 -102-


participant were a direct holder of Loans if such Bank has previously
given notice of such participation to the Company.

     (c)  Each Bank may assign to one or more Banks or Eligible
Assignees all or a portion of its interests, rights and obligations
under this Agreement (including all or a portion of its Commitments
and the same portion of the related Loans at the time owing to it and
the related Note held by it); PROVIDED (1) other than in the case of
an assignment to a Person at least 50% owned by the assignor Bank, or
by a common parent of both, or to another Bank, the Agent and the
Company must give their respective prior written consent, which
consent will not be unreasonably withheld; (2) the aggregate amount of
the Commitments and/or Loans of the assigning Bank subject to each
such assignment (determined as of the date the Assignment Agreement
with respect to such assignment is delivered to the Agent) shall in no
event be less $10,000,000 (or $1,000,000 in the case of an assignment
between Banks) (except for certain exceptions approved by the Company
and the Agent or where all of a Bank's Commitments and Loans are being
assigned) and shall be in an amount that is an integral multiple of
$1,000,000 (except for certain exceptions approved by the Company and
the Agent or where all of a Bank's Commitments and Loans are being
assigned); (3) the assigning Bank shall contemporaneously assign to
such assignee Bank or Eligible Assignee an equal percentage of the
assigning Bank's Letter of Credit Commitment and all of the assigning
Bank's other rights and obligations under the Letter of Credit
Agreement; and (4) the parties to each such assignment shall execute
and deliver to the Agent, for its acceptance and recording in its
records, an Assignment Agreement with blanks appropriately completed,
together with the Notes subject to such assignment and a processing
and recordation fee of $2,000 (for which the Company shall have no
liability except in the case of assignments required by the Company
pursuant to SECTION 6.1, 6.3 or 6.6, in which case such fee shall be
paid by the Company).  Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in each
Assignment Agreement, (A) the assignee thereunder shall be a party
hereto and, to the extent provided in such Assignment Agreement, have
the rights and obligations of a Bank hereunder, and (B) the Bank
making such assignment shall, to the extent provided in such
assignment, be released from its obligations under this Agreement
(and, in the case of an Assignment Agreement covering all or the
remaining portion of an assigning Bank's rights and obligations under
this Agreement, such Bank shall cease to be a party hereto).

     (d)  By executing and delivering an Assignment Agreement, the
Bank assignor thereunder and the assignee thereunder confirm to and
agree with each other and the other parties hereto as follows:  (1)
other than the representation and warranty that it is the legal and
beneficial owner of the interest being assigned thereby, such 

                                 -103-


assignor Bank makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or
representations made in or in connection with any Credit Document or
the execution, legality, validity, enforceability, genuineness,
sufficiency or value of any Credit Document; (2) such assignor Bank
makes no representation or warranty and assumes no responsibility with
respect to the financial condition of the Company or the performance
or observance by the Company of any of its obligations under any
Credit Document; (3) such assignee confirms that it has received a
copy of this Agreement, together with copies of the financial
statements of the Company previously delivered in accordance herewith
and such other documents and information as it has deemed appropriate
to make its own credit analysis and decision to enter into such
Assignment Agreement; (4) such assignee will, independently and
without reliance upon the Agent, such assignor Bank or any other Bank
and based on such documents and information as it shall deem appropri-
ate at the time, continue to make its own credit decisions in taking
or not taking action under the Credit Documents; (5) such assignee
appoints and authorizes the Agent to take such action as agent on its
behalf and to exercise such powers under the Credit Documents as are
delegated to the Agent by the terms hereof, together with such powers
as are reasonably incidental thereto, and (6) such assignee agrees
that it will perform in accordance with their terms all obligations
that by the terms of the Credit Documents are required to be performed
by it as a Bank.

     (e)  The Agent shall maintain at its office a copy of each
Assignment Agreement delivered to it and a record of the names and
addresses of the Banks and the Commitments of, and principal amount of
the Loans owing to, each Bank from time to time.  The entries in such
record shall be conclusive, in the absence of manifest error, and the
Company, the Agent and the Banks may treat each Person the name of
which is recorded therein as a Bank hereunder for all purposes of the
Credit Documents.  Such records shall be available for inspection by
the Company or any Bank at any reasonable time and from time to time
upon reasonable prior notice.

     (f)  Upon its receipt of an Assignment Agreement executed by an
assigning Bank and the assignee thereunder together with the Note
subject to such assignment, the written consent to such assignment and
the fee payable in respect thereto, the Agent shall, if such
Assignment Agreement has been completed with blanks appropriately
filled, (1) accept such Assignment Agreement; (2) record the
information contained therein in its records, and (3) give prompt
notice thereof to the Company.  Contemporaneously with the receipt by
the Agent of an Assignment Agreement, the Company, at its own expense,
shall execute and deliver to the Agent in exchange for each
surrendered Note a new Note payable to the order 

                                 -104-


of such assignee in an amount equal to the Commitments and/or Loans
assumed by it pursuant to such Assignment Agreement and, if the
assignor Bank has retained Commitments and/or Loans hereunder, new
Notes payable to the order of the assignor Bank in an amount equal to
the Commitments and/or Loans retained by it.  Such new Notes shall be
in an aggregate principal amount equal to the principal amount of each
surrendered Note, shall be dated the effective date of such Assignment
Agreement and shall otherwise be in substantially the form of the
surrendered Notes.  Thereafter, each surrendered Note shall be marked
cancelled and returned to the Company.

     (g)  Any Bank may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this
Section, disclose to the assignee or participant or proposed assignee
or participant any information relating to the Company furnished to
such Bank by or on behalf of the Company.

     (h)  Any assignment by a Bank pursuant to this SECTION 12.6 shall
not result in any single Bank holding in excess of 25% of the
Aggregate Commitment at any one time.

     (i)  Notwithstanding any other provision of this SECTION 12.6,
TCB and its Affiliates may not assign their rights hereunder unless,
after giving effect to such assignment, TCB and its Affiliates would
have an aggregate Commitment Percentage of at least 10%.

     (j)  Notwithstanding anything herein to the contrary, each Bank
may pledge and assign all or any portion of its rights and interests
under the Credit Documents to any Federal Reserve Bank.

     12.7.     SURVIVAL; TERM; REINSTATEMENT.  In addition to the
other provisions of this Agreement expressly stated to survive the
termination of this Agreement, the obligations of the Company under
SECTIONS 6, 12.3 and 12.4 and the last sentence of this SECTION 12.7
and the obligations of the Banks under SECTION 12.8 shall survive the
termination of this Agreement.  The term of this Agreement shall be
until (a) the full and final payment of all Notes, (b) the termination
of all Commitments and (c) the payment of all amounts due under the
Credit Documents.  The Company agrees that if at any time all or any
part of any payment previously applied by any Bank to any Loan or
other sum hereunder is or must be returned by or recovered from such
Bank for any reason (including the order of any bankruptcy court), the
Credit Documents shall automatically be reinstated to the same effect
as if the prior application had not been made, and the Company hereby
agrees to indemnify such Bank against, and to save and hold such Bank
harmless from, any required return by or recovery from such Bank of

                                 -105-


any such payment because of its being deemed preferential under
applicable Legal Requirements, or for any other reason.  

     12.8.     LIMITATION OF INTEREST.  The parties to this Agreement
intend to strictly comply with all applicable laws, including
applicable usury laws.  Accordingly, the provisions of this
SECTION 12.8 shall govern and control over every other provision of
any Credit Document which conflicts or is inconsistent with this
Section, even if such provision declares that it controls.  As used in
this Section, the term "interest" includes the aggregate of all
charges, fees, benefits or other compensation which constitute
interest under applicable law; PROVIDED that, to the maximum extent
permitted by applicable law, (a) any non-principal payment shall be
characterized as an expense or as compensation for something other
than the use, forbearance or detention of money, and not as interest
and (b) all interest at any time contracted for, taken, reserved,
retained, charged or received shall be amortized, prorated, allocated
and spread, in equal parts during the full term of the Loans and the
Commitments.  In no event shall the Company or any other Person be
obligated to pay, or the Agent or any Bank have any right or privilege
to reserve, receive or retain, (x) any interest in excess of the
maximum amount of nonusurious interest permitted under the laws of the
State of Texas or the applicable laws (if any) of the United States or
of any other state or (y) total interest in excess of the amount which
the Agent or such Bank could lawfully have contracted for, taken,
reserved, received, retained or charged had the interest been
calculated for the full term of the Loans at the Highest Lawful Rate. 
On each day, if any, that the interest rate (the "STATED RATE") called
for under any Credit Document exceeds the Highest Lawful Rate, the
rate at which interest shall accrue shall automatically be fixed by
operation of this sentence at the Highest Lawful Rate for that day,
and shall remain fixed at the Highest Lawful Rate for each day
thereafter until the total amount of interest accrued equals the total
amount of interest which would have accrued if there were no such
ceiling rate as is imposed by this sentence.  Thereafter, interest
shall accrue at the Stated Rate unless and until the Stated Rate again
exceeds the Highest Lawful Rate when the provisions of the immediately
preceding sentence shall again automatically operate to limit the
interest accrual rate.  The daily interest rates to be used in
calculating interest at the Highest Lawful Rate shall be determined by
dividing the applicable Highest Lawful Rate per annum by the number of
days in the calendar year for which such calculation is being made. 
None of the terms and provisions contained in any Credit Document
which directly or indirectly relate to interest shall ever be
construed without reference to this Section, or be construed to create
a contract to pay for the use, forbearance or detention of money at an
interest rate in excess of the Highest Lawful Rate.  If 

                                 -106-


the term of any of the Notes is shortened by reason of acceleration of
maturity as a result of any Default or by any other cause, or by
reason of any required or permitted prepayment, and if for that (or
any other) reason the Agent or any Bank at any time, including the
stated maturity, is owed or receives (and/or has received) interest in
excess of interest calculated at the Highest Lawful Rate, then and in
any such event all of any such excess interest shall be cancelled
automatically as of the date of such acceleration, prepayment or other
event which produces the excess, and, if such excess interest has been
paid to the Agent or such Bank, it shall be credited PRO TANTO against
the then-outstanding principal balance of the Company's obligations to
the Agent or such Bank, effective as of the date or dates when the
event occurs which causes it to be excess interest, until such excess
is exhausted or all of such principal has been fully paid and
satisfied, whichever occurs first, and any remaining balance of such
excess shall be promptly refunded to its payor.

     12.9.     CAPTIONS.  Captions and section headings appearing
herein are included solely for convenience of reference and are not
intended to affect the interpretation of any provision of this
Agreement.

     12.10.    COUNTERPARTS.  Each Credit Document may be executed in
any number of counterparts, all of which taken together shall consti-
tute one and the same agreement and any of the parties hereto may
execute such Credit Document by signing any such counterpart.

     12.11.    GOVERNING LAW.  EXCEPT TO THE EXTENT OTHERWISE
SPECIFIED THEREIN, EACH CREDIT DOCUMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF TEXAS AND THE
UNITED STATES OF AMERICA.  THE COMPANY HEREBY SUBMITS TO THE
NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE
SOUTHERN DISTRICT OF TEXAS AND OF ANY TEXAS STATE COURT SITTING IN
HARRIS COUNTY, TEXAS FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT
OF OR RELATING TO THE CREDIT DOCUMENTS OR THE TRANSACTIONS
CONTEMPLATED THEREBY.  THE COMPANY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH
A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT
HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

     12.12.    SEVERABILITY.  Whenever possible, each provision of the
Credit Documents shall be interpreted in such manner as to be
effective and valid under applicable law.  If any provision of any
Credit Document shall be invalid, illegal or unenforceable in any
respect under any applicable law, the validity, legality and 

                                 -107-


enforceability of the remaining provisions of such Credit Document
shall not be affected or impaired thereby.

     12.13.    CHAPTER 15 NOT APPLICABLE.  Chapter 15 of the Texas
Credit Code shall not apply to any Credit Document or to any
Commitment or Loan, nor shall any Credit Document be governed by or be
subject to the provisions of such Chapter 15 in any manner whatsoever.

                                 -108-

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement
to be duly executed and delivered effective as of the day and year
first above written.
