ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS
- ------    ------------------------------------

     On September 30, 1997, Inland Resources Inc. (the "Company") acquired the
Utah assets (the "EREC Properties") of Equitable Resources Energy Company
("EREC") for $55.4 million in cash (subject to various post closing
adjustments).  The EREC Properties consist of 279 gross (184 net) oil and gas
wells, 23,400 net undeveloped acres, water rights, a water transportation and
distribution system and a gas gathering system.  The undeveloped acreage
provides the Company with approximately 585 additional drillsites in the
Monument Butte Field.  The acquisition of the EREC Properties also included
operating rights to four approved water flood units (encompassing 142 of the
wells acquired).

     Management believes that the EREC Properties have significant development
potential which will enable the Company to increase its cash flow from
operations and reserve base at a cost efficient rate due to the proximity of the
EREC Properties to the Company's existing properties.  The EREC Properties are
geographically concentrated in proximity to the Company's properties in the
Monument Butte Field, thereby enabling the Company to operate the properties
without incurring significant incremental general and administrative expenses.
Of the 279 gross wells acquired, the Company already operated 48 of the wells
and EREC operated 227 of the wells so that the Company now operates 275 of the
wells.

     The Company financed the acquisition of the EREC Properties with a portion
of the proceeds of a new credit facility with Trust Company of the West and TCW
Asset Management Company, in their capacities as noteholder and agent
(collectively "TCW").

ITEM 5.   OTHER EVENTS.
- ------    ------------ 

     On September 30, 1997, the Company and its wholly owned subsidiary, Inland
Production Company ("IPC"), closed a Credit Agreement with TCW pursuant to which
TCW loaned IPC $75,000,000, and IPC used a portion of such proceeds to purchase
the EREC Properties.  The loan from TCW is secured by a second lien on all
assets of IPC and is guaranteed by the Company.

     The Company and IPC also closed a Credit Agreement on September 30, 1997
with ING (U.S.) Capital Corporation ("ING") providing IPC with a line of credit
equal to an initial borrowing base of $45,000,000.  This loan is secured by a
first lien on all assets of IPC and is also guaranteed by the Company.  IPC drew
down an initial $17.8 million under the Credit Agreement with ING which, when
combined with excess borrowings from TCW, were used to fund repayment in full of
its existing credit facility with Canadian Imperial Bank of Commerce.

     The Credit Agreement with ING constitutes a revolving line of credit until
March 31, 1999, at which time it converts to a term loan payable in quarterly
installments through March 29, 2003, when the final installment is due and
payable in full.  The quarterly installments are in the amount of $4,000,000 for
the first three quarters, $3,000,000 for the next four quarters, $2,500,000 for
the next four quarters, $2,250,000 for the next four quarters, and $2,000,000 on
March 29, 2003.  The ING 

                                      -2-
<PAGE>
 
loan bears interest, at IPC's option, at either (i) the average prime rates
announced from time to time by The Chase Manhattan Bank, Citibank, N.A. and
Morgan Guaranty Trust Company of New York plus 0.5% per annum; or (ii) at the
LIBOR rate plus 1.75%.

     The TCW loan is payable interest only, at a rate of 9.75% per annum,
quarterly until the earlier of December 31, 2003 or the date upon which the ING
loan is paid in full, at which time the TCW loan is payable in quarterly
installments of principal and interest over twelve quarterly installments, with
the principal installments equaling $6,250,000 for the first four quarters,
$8,750,000 for the fifth through eighth quarters and $3,750,000 for the ninth
through twelfth quarters.  The Company also granted warrants to TCW in
connection with the TCW Credit Agreement to purchase 100,000 shares of common
stock (subject to anti-dilution adjustments) for an exercise price of $10.00 per
share (subject to anti-dilution adjustments) at any time after September 23,
2000 and before September 23, 2007.  The Company also granted registration
rights in connection with such warrants.  TCW is also entitled to additional
interest on $65,000,000 of the TCW loan in such amount that will yield to it a
12.5% internal rate of return on such principal amount, such payment to be made
concurrently with the final payment of all principal and interest on the TCW
loan.  For purposes of this internal rate of return calculation, IPC is also
given credit for payment of a funding fee in the amount of 3% of the total loan
amount paid to TCW at the closing of the loan transaction.  TCW may also elect
to "put" the warrant back to the Company upon payment in full of the TCW loan in
an amount which will cause TCW to achieve a 12.5% internal right of return on
the last $10,000,000 of the TCW loan.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Stockholders of
   Inland Resources Inc.:


We have audited the accompanying statements of revenues and direct operating
expenses for certain of the oil and gas properties (the "Properties") of
Equitable Resources Energy Company ("Equitable") acquired by INLAND RESOURCES
INC. for each of the years ended December 31, 1996 and 1995.  These financial
statements are the responsibility of Inland Resources Inc.'s management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

The statements of revenues and direct operating expenses for the Properties
acquired from Equitable were prepared for the purpose of complying with the
rules and regulations of the Securities and Exchange Commission as described in
Note 1, and are not intended to be a complete presentation of the Properties'
financial position, results of operations and cash flows.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the revenues and direct operating expenses for the
Properties acquired from Equitable for each of the years ended December 31, 1996
and 1995, in conformity with generally accepted accounting principles.

(1)  BASIS OF PRESENTATION
     ---------------------

On September 30, 1997, Inland Resources Inc. (the "Company") acquired all
rights, title and interest in certain oil and gas properties (the "Properties")
as described in the Agreement of Sale and Purchase between the Company and
Equitable Resources Energy Company ("Equitable").  The acquisition had an
effective date of April 1, 1997.  The Properties acquired by the Company consist
of oil and gas interests in approximately 300 properties and the associated
facilities located in the Uinta Basin of North-eastern Utah.

The accompanying Statements of Revenues and Direct Operating Expenses were
derived from the historical accounting records maintained by Equitable.  The
statements have been prepared on the accrual basis of accounting.  The
statements do not include depreciation, depletion and amortization, general and
administrative, income tax or interest expense as these costs may not be
comparable to the expenses expected to be incurred in the future.  The revenues
and direct operating expenses for the periods presented are also not necessarily
indicative of results to be expected in the future.

(2)  UNAUDITED INTERIM FINANCIAL INFORMATION
     ---------------------------------------

The accompanying financial information for the six-month periods ended June 30,
1997 and 1996 is unaudited but reflects, in the opinion of the Company's
management, all adjustments (which include only normal recurring adjustments)
necessary to present fairly the oil and gas revenues and direct oil and gas
operating expenses of the Properties for such periods.  The oil and gas revenues
and direct oil and gas operating expenses for such interim periods are not
necessarily indicative of results to be expected for the full year.

(3)  SUMMARY OIL AND GAS RESERVE INFORMATION (UNAUDITED)
     ---------------------------------------------------

Supplemental oil and gas reserve information related to the Properties is
presented in accordance with Statement of Financial Accounting Standards No. 69,
"Disclosures about Oil and Gas Producing Activities."  Net proved oil and gas
reserves of the Properties as of December 31, 1996 and 1995 were estimated by
Netherland, Sewell & Associates, independent petroleum engineering consultants.

The following tables set forth information for the years ended December 31, 1996
and 1995, with respect to changes in the Properties' proved reserves.
Quantities of natural gas are expressed in terms of thousand cubic feet (mcf)
and oil in barrels (bbls).

had the transaction actually occurred on January 1, 1996, January 1, 1997 or
June 30, 1997, as applicable.

               Notes to Unaudited Pro Forma Financial Statements



1.   Basis of Presentation:
     ----------------------

     The unaudited Pro Forma Consolidated Statements of Operations are based on
     Inland's audited financial statements and the audited statement of revenues
     and direct operating expenses of certain oil and gas properties of EREC for
     the year ended December 31, 1996 and on Inland's unaudited financial
     statements and on the unaudited statement of revenues and direct operating
     expenses for certain oil and gas properties acquired from EREC for the six
     months ended June 30, 1997, and upon the adjustments and assumptions
     described below.

2.   Pro Forma Adjustments:
     ----------------------

     The unaudited pro forma statements of income reflect the following
     adjustments:

     A.   Sales of oil and gas and operating costs were adjusted based on the
          audited statement of revenues and direct operating expenses for the
          year ended December 31, 1996 and from the unaudited statement of
          revenues and direct operating expenses for the six months ended June
          30, 1997.
 
     B.   Depletion, depreciation and amortization is adjusted based on Inland's
          July 1, 1997 in-house reserve report for the acquired EREC properties
          and the portion of the purchase price allocated to proved properties.

     C.   The unaudited Pro Forma Consolidated Statements of Operations do not
          include any adjustment for net general and administrative expense
          since the increase to gross general and administrative expense related
          to the acquisition is offset by COPAS producing overhead
          reimbursements on the operated properties acquired.

     D.   Interest expense is adjusted using Inland's blended cost of capital to
          finance the transaction.

     E.   The Pro Forma Condensed Consolidated Balance Sheet includes
          adjustments to reflect the purchase of the EREC oil and gas and other
          assets for $55.5 million using funds provided by new issues of long-
          term debt. The purchase price allocation includes payment for oil and
          gas assets, a long-term receivable of $2.4 million and debt issue
          costs of $2.2 million.

theretofore received by such Bank on such Note. Interest on each Note shall
accrue and be due and payable as provided herein and therein, with Eurodollar
Loans bearing interest at the Eurodollar Rate and Base Rate Loans bearing
interest at the Base Rate (subject to the applicability of the Late Payment Rate
and limited by the provisions of Section 9.8). Subject to the terms and
conditions hereof, Borrower may borrow, repay, and reborrow hereunder. It is
expressly understood that Banks' commitment to make Loans is determined only by
reference to the Borrowing Base from time to time in effect, and the aggregate
amount of the Notes and the amount specified in the Security Documents are
specified at a greater amount only for the convenience of the parties to avoid
the necessity of preparing and recording supplements to the Security Documents.

      Section 2.2.  Requests for New Loans.  Borrower must give to Agent written
                    ----------------------                                      
notice (or telephonic notice promptly confirmed in writing) of any requested
Borrowing of new Loans to be advanced by Banks.  Each such notice constitutes a
"Borrowing Notice" hereunder and must:

          (a)  specify (i) the aggregate amount of any such Borrowing of new
     Base Rate Loans and the date on which such Base Rate Loans are to be
     advanced, or (ii) the aggregate amount of any such Borrowing of new
     Eurodollar Loans, the date on which such Eurodollar Loans are to be
     advanced (which shall be the first day of the Interest Period which is to
     apply thereto), and the length of the applicable Interest Period; and

          (b)  be received by Agent not later than 1:00 p.m., New York, New York
     time, on (i) the day on which any such Base Rate Loans are to be made, or
     (ii) the third Business Day preceding the day on which any such Eurodollar
     Loans are to be made.

Each such written request or confirmation must be made in the form and substance
of the "Borrowing Notice" attached hereto as Exhibit B, duly completed.  Each
such telephonic request shall be deemed a representation, warranty,
acknowledgment and agreement by Borrower as to the matters which are required to
be set out in such written confirmation.  Upon receipt of any such Borrowing
Notice, Agent shall give each Bank prompt notice of the terms thereof.  If all
conditions precedent to such new Loans have been met, each Bank will on the date
requested promptly remit to Agent at Agent's office in New York, New York the
amount of such Bank's new Loan in immediately available funds, and upon receipt
of such funds, unless to its actual knowledge any conditions precedent to such
Loans have been neither met nor waived as provided herein, Agent shall promptly
make such Loans available to Borrower.  Unless Agent shall have received prompt
notice from a Bank that such Bank will not make available to Agent such Bank's
new Loan, Agent may in its discretion assume that such Bank has made such Loan
available to Agent in accordance with this section and Agent may if it chooses,
in reliance upon such assumption, make such Loan available to Borrower.  If and
to the extent such Bank shall not so make its new Loan available to Agent, such
Bank and Borrower severally agree to pay or repay to Agent within three days
after demand the amount of such Loan together with interest thereon, for each
day from the date such amount was made available to Borrower until the date such
amount is paid or repaid to Agent, with interest at (i) the Federal Funds Rate,
if such Bank is making such payment and (ii) the interest rate applicable at the
time to the other new Loans made on such date, if Borrower is making such
repayment.  If neither such Bank nor Borrower pay or repay to Agent such amount
within such three-day period, Agent shall in addition to such amount be entitled
to recover from such Bank and from Borrower, on demand, interest thereon at the
Late Payment Rate, calculated from the date such amount was made available to
Borrower.  The failure of any Bank to make any new Loan to be made by it
hereunder shall not relieve any other Bank of its obligation hereunder, if any,
to make its new Loan, but no Bank shall be responsible for the failure of any
other Bank to make any new Loan to be made by such other Bank.

      Section 2.3.  Continuations and Conversions of Existing Loans.  Borrower
                    -----------------------------------------------           
may make the following elections with respect to Loans already outstanding: to
convert Base Rate Loans to Eurodollar Loans, to convert Eurodollar Loans to Base
Rate Loans on the last day of the Interest Period applicable thereto, or to
continue Eurodollar Loans beyond the expiration of such Interest Period by
designating a new Interest Period to take effect at the time of such expiration.
In making such elections, Borrower may combine existing Loans made pursuant to
separate Borrowings into one new Borrowing or divide existing Loans made
pursuant to one Borrowing into separate new Borrowings.  To make any such
election, Borrower must give to Agent written notice (or telephonic notice
promptly confirmed in writing) of any such conversion or continuation of
existing Loans, with a separate notice given for each new Borrowing.  Each such
notice constitutes a "Continuation/Conversion Notice" hereunder and must:

          (a)  specify the existing Loans which are to be continued or
     converted;

          (b)  specify (i) the aggregate amount of any Borrowing of Base Rate
     Loans into which such existing Loans are to be continued or converted and
     the date on which such continuation or conversion is to occur, or (ii) the
     aggregate amount of any Borrowing of Eurodollar Loans into which such
     existing Loans are to be continued or converted, the date on which such
     continuation or conversion is to occur (which shall be the first day of the
     Interest Period which is to apply to such Eurodollar Loans), and the length
     of the applicable Interest Period; and

          (c)  be received by Agent not later than 1:00 p.m., New York, New York
     time, on (i) the day on which any such continuation or conversion to Base
     Rate Loans is to occur, or (ii) the third Business Day preceding the day on
     which any such continuation or conversion to Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and substance
of the "Continuation/Conversion Notice" attached hereto as Exhibit C, duly
completed.  Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by Borrower as to the matters which are
required to be set out in such written confirmation.  Upon receipt of any such
Borrowing Notice, Agent shall give each Bank prompt notice of the terms thereof.
Each Borrowing Notice shall be irrevocable and binding on Borrower.  During the
continuance of any Default, Borrower may not make any election to convert
existing Loans into Eurodollar Loans or continue existing Loans as Eurodollar
Loans.  If (due to the existence of a Default or for any other reason) Borrower
fails to timely and properly give any notice of continuation or conversion with
respect to a Borrowing of existing Eurodollar Loans at least three days prior to
the end of the Interest Period applicable thereto, such Eurodollar Loans shall
automatically be converted into Base Rate Loans at the end of such Interest
Period.  No new funds shall be repaid by Borrower or advanced by any Bank in
connection with any continuation or conversion of existing Loans pursuant to
this section, and no such continuation or conversion shall be deemed to be a new
advance of funds for any purpose; such continuations and conversions merely
constitute a change in the interest rate applicable to already outstanding
Loans.

      Section 2.4.  Use of Proceeds.  Borrower shall use the proceeds of the
                    ---------------                                         
first Loan to pay in full the Debt outstanding under the CIBC Credit Agreement.
Borrower shall use all subsequent Loans to (i) finance future proved oil and gas
acquisitions and development by Borrower, (ii) finance the Crysen Acquisition
(but only if all Banks first approve the terms thereof) and (iii) provide
working capital for its operations.  In no event shall the funds from any Loan
be used directly or indirectly by any Person for personal, family, household or
agricultural purposes or for the purpose, whether immediate, incidental or
ultimate, of purchasing, acquiring or carrying any "margin stock" or any "margin
securities" (as such terms are defined respectively in Regulation U and
Regulation G promulgated by

                                       8
<PAGE>
 
the Board of Governors of the Federal Reserve System) or to extend credit to
others directly or indirectly for the purpose of purchasing or carrying any such
margin stock or margin securities. Borrower represents and warrants that
Borrower is not engaged principally, or as one of Borrower's important
activities, in the business of extending credit to others for the purpose of
purchasing or carrying such margin stock or margin securities.

      Section 2.5.  Fees.
                    ---- 

     (a)  Commitment Fees.  In consideration of each Bank's commitment to make
          ---------------                                                     
Loans, Borrower will pay to Agent for the account of each Bank a commitment fee
determined on a daily basis by applying a rate of one-half of one percent (.50%)
per annum to such Bank's Percentage Share of the unused portion of the Borrowing
Base on each day during the Commitment Period, determined for each such day by
deducting from the amount of the Borrowing Base at the end of such day the
Facility Usage.  This commitment fee shall be due and payable in arrears on the
last day of each Fiscal Quarter and at the end of the Commitment Period.

     (b) Facility Fee.  In addition to all other amounts due to Agent under the
         ------------                                                          
Loan Documents, Borrower will pay a facility fee to Agent, for its own account,
as described in a letter agreement of even date herewith between Agent and
Borrower.

      Section 2.6.  Optional Prepayments.  Borrower may, upon five Business
                    --------------------                                   
Days' notice to each Bank, from time to time and without premium or penalty
prepay the Notes, in whole or in part, so long as the aggregate amounts of all
partial prepayments of principal on the Notes equals $1,000,000 or any higher
integral multiple of $1,000,000, so long as Borrower does not prepay any
Eurodollar Loan, and so long as Borrower does not make any prepayments which
would reduce the unpaid principal balance of any Loan to less than $100,000
without first either (a) terminating this Agreement or (b) providing assurance
satisfactory to Agent in its discretion that Banks' legal rights under the Loan
Documents are in no way affected by such reduction.  Each partial prepayment of
principal made after the end of the Commitment Period shall be applied to the
regular installments of principal due under the Notes in the inverse order of
their maturities.  Each prepayment of principal under this section shall be
accompanied by all interest then accrued and unpaid on the principal so prepaid.
Any principal or interest prepaid pursuant to this section shall be in addition
to, and not in lieu of, all payments otherwise required to be paid under the
Loan Documents at the time of such prepayment.

      Section 2.7.  Mandatory Prepayments.
                    --------------------- 

     (a) Borrower will make all payments on the Obligations which are required
under the Intercreditor Agreement, including all prepayments of principal on the
Notes which are required under Section 3(a)(iv) of the Intercreditor Agreement.

     (b)  If at any time the Facility Usage is in excess of the Borrowing Base
(such excess being herein called a "Borrowing Base Deficiency"), Borrower shall,
within five Business Days after Agent gives notice of such fact to Borrower,
either:

          (i)  prepay the principal of the Loans in an aggregate amount at least
     equal to such Borrowing Base Deficiency, or

          (ii) give notice to Agent electing to prepay the principal of the
     Loans in up to three monthly installments in an aggregate amount at least
     equal to such Borrowing Base Deficiency, with each such installment equal
     to or in excess of one-third of such Borrowing Base

                                       9
<PAGE>
 
     Deficiency, and with the first such installment to be paid one month after
     the giving of such notice and the subsequent installments to be due and
     payable at one month intervals thereafter until such Borrowing Base
     Deficiency has been eliminated, or

          (iii) give notice to Agent that Borrower desires to provide Agent with
     deeds of trust, mortgages, chattel mortgages, security agreements,
     financing statements and other security documents in form and substance
     satisfactory to Agent, granting, confirming, and perfecting first and prior
     liens or security interests in collateral acceptable to all Banks, to the
     extent needed to allow all Banks to increase the Borrowing Base (as they in
     their reasonable discretion deem consistent with prudent oil and gas
     banking industry lending standards at the time) to an amount which
     eliminates such Borrowing Base Deficiency, and then provide such security
     documents within thirty days after Agent specifies such collateral to
     Borrower.  If, prior to any such specification by Agent, Required Lenders
     determine that the giving of such security documents will not serve to
     eliminate such Borrowing Base Deficiency, then, within five Business Days
     after receiving notice of such determination, Borrower will elect to make,
     and thereafter make, the prepayments specified in either of the preceding
     subsections (i) or (ii) of this subsection (b).

     (c)  Each prepayment of principal under this section shall be accompanied
by all interest then accrued and unpaid on the principal so prepaid.  Any
principal or interest prepaid pursuant to this section shall be in addition to,
and not in lieu of, all payments otherwise required to be paid under the Loan
Documents at the time of such prepayment.

      Section 2.8.  Scheduled Principal Payments.  Beginning on June 28, 1999,
                    ----------------------------                              
and on each Quarterly Payment Date thereafter, Borrower will, in addition to
paying any interest then due on the Loans, make a principal payment in

The principal installments required by this Section 2.8 are in addition to all
other principal payments required by the terms of this Agreement.

      Section 2.9.  Initial Borrowing Base.  During the period from the date
                    ----------------------                                  
hereof to the first Determination Date the Borrowing Base shall be $45,000,000.

      Section 2.10.  Subsequent Determinations of Borrowing Base.  By March 1
                     -------------------------------------------             
and July 15 of each year Borrower shall furnish to each Bank all information,
reports and data which Agent has then requested concerning Related Persons'
businesses and properties (including their oil and gas properties and interests
and the reserves and production relating thereto), together with the Engineering
Report described in Section C.1(d) or C.1(e) of Annex C, as applicable.  Within
thirty days after receiving such information, reports and data, Required Lenders
shall agree upon an amount for the Borrowing Base (provided that all Banks must
agree to any increase in the Borrowing Base) and Agent shall by notice to
Borrower designate such amount as the new Borrowing Base available to Borrower
hereunder, which designation shall take effect immediately on the date such
notice is sent (herein called a "Determination Date") and shall remain in effect
                                 ------------------                             
until but not including the next date as of which the Borrowing Base is
redetermined.  If Borrower does not furnish all such information, reports and
data by the date specified in the first sentence of this section, Agent may
nonetheless designate the Borrowing Base at any amount which Required Lenders
determine and may redesignate the Borrowing Base from time to time thereafter
until each Bank receives all such information, reports and data, whereupon
Required Lenders shall designate a new Borrowing Base as described above.
Required Lenders shall determine the amount of the Borrowing Base based upon the
loan collateral value which they in their discretion assign to the various
proved oil and gas properties of Related Persons at the time in question and
based upon such other credit factors (including without limitation the assets,
liabilities, cash flow, hedged and unhedged exposure to price, foreign exchange
rate, and interest rate changes, business, properties, prospects, management and
ownership of Borrower and its Affiliates) as they in their discretion deem
significant.  It is expressly understood that Banks and Agent have no obligation
to agree upon or designate the Borrowing Base at any particular amount, whether
in relation to the aggregate face amount of the Notes or otherwise, and that
Banks' commitments to advance funds hereunder is determined by reference to the
Borrowing Base from time to time in effect, which Borrowing Base shall be used
for calculating commitment fees under Section 2.5 and, to the extent permitted
by Law and regulatory authorities, for the purposes of capital adequacy
determination and reimbursements under Section 3.2.  It is further understood
that the scheduled principal payments set forth in Section 2.8 are based upon
the Borrowing Base as in effect on the date hereof and that Banks and Agent
shall not increase the Borrowing Base without (i) an amendment to such scheduled
principal payments as determined by the Banks in connection with such Borrowing
Base increase and (ii) the consent of Tamco to such amendment to such scheduled
principal payments.

                        ARTICLE III - Payments to Banks
                                      -----------------

      Section 3.1.  General Procedures.  Borrower will make each payment which
                    ------------------                                        
it owes under the Loan Documents to Agent for the account of the Lender to whom
such payment is owed.  Each such payment must be received by Agent not later
than 11:00 a.m., New York, New York time, on the date such payment becomes due
and payable, in lawful money of the United States of America, without set-off,
deduction or counterclaim, and in immediately available funds.  Any payment
received by Agent after such time will be deemed to have been made on the next
following Business Day.  Should any such payment become due and payable on a day
other than a Business Day, the maturity of such payment shall be extended to the
next succeeding Business Day, and, in the case of a payment of principal or past
due interest, interest shall accrue and be payable thereon for the period of
such extension as provided in the Loan Document under which such payment is due.
Each payment under a

                                       11
<PAGE>
 
Loan Document shall be due and payable at the place provided therein and, if no
specific place of payment is provided, shall be due and payable at the place of
payment of Agent's Note. When Agent collects or receives money on account of the
Obligations, Agent shall distribute all money so collected or received, and each
Lender shall apply all such money so distributed, as follows:

          (a)  first, for the payment of all Obligations which are then due (and
     if such money is insufficient to pay all such Obligations, first to any
     reimbursements due Agent under Section C.8 of Annex C of this Agreement or
     Section 9.4 and then to the partial payment of all other Obligations then
     due in proportion to the amounts thereof, or as Lenders shall otherwise
     agree);

          (b)  then for the prepayment of amounts owing under the Loan Documents
     (other than principal on the Notes) if so specified by Borrower;

          (c)  then for the prepayment of principal on the Notes, together with
     accrued and unpaid interest on the principal so prepaid; and

          (d)  last, for the payment or prepayment of any other Obligations.

All payments applied to principal or interest on any Note shall be applied first
to any interest then due and payable, then to principal then due and payable,
and last to any prepayment of principal and interest in compliance with Sections
2.6 and 2.7.  All distributions of amounts described in any of subsections (b),
(c) or (d) above shall be made by Agent pro rata to each Lender then owed
Obligations described in such subsection in proportion to all amounts owed to
all Lenders which are described in such subsection.

      Section 3.2.  Capital Reimbursement.  If either (a) the introduction or
                    ---------------------                                    
implementation of or the compliance with or any change in or in the
interpretation of any Law, or (b) the introduction or implementation of or the
compliance with any request, directive or guideline from any central bank or
other governmental authority (whether or not having the force of Law) affects or
would affect the amount of capital required or expected to be maintained by any
Lender or any corporation controlling any Lender, then, upon demand by such
Lender, Borrower will pay to Agent for the benefit of such Lender, from time to
time as specified by such Lender, such additional amount or amounts which such
Lender shall determine to be appropriate to compensate such Lender or any
corporation controlling such Lender in light of such circumstances, to the
extent that such Lender reasonably determines that the amount of any such
capital would be increased or the rate of return on any such capital would be
reduced by or in whole or in part based on the existence of the face amount of
such Lender's Loans or commitments under this Agreement.

      Section 3.3.  Increased Cost of Eurodollar Loans.  If any applicable Law
                    ----------------------------------                        
(whether now in effect or hereinafter enacted or promulgated, including
Regulation D) or any interpretation or administration thereof by any
governmental authority charged with the interpretation or administration thereof
(whether or not having the force of Law):

          (a)  shall change the basis of taxation of payments to any Lender of
     any principal, interest, or other amounts attributable to any Eurodollar
     Loan or otherwise due under this Agreement in respect of any Eurodollar
     Loan (other than taxes imposed on the overall net income of such Lender or
     any lending office of such Lender by any jurisdiction in which such Lender
     or any such lending office is located); or

                                       12
<PAGE>
 
          (b)  shall change, impose, modify, apply or deem applicable any
     reserve, special deposit or similar requirements in respect of any
     Eurodollar Loan (excluding those for which such Lender is fully compensated
     pursuant to adjustments made in the definition of Eurodollar Rate) or
     against assets of, deposits with or for the account of, or credit extended
     by, such Lender; or

          (c)  shall impose on any Lender or the interbank Eurocurrency deposit
     market any other condition affecting any Eurodollar Loan, the result of
     which is to increase the cost to any Lender of funding or maintaining any
     Eurodollar Loan or to reduce the amount of any sum receivable by any Lender
     in respect of any Eurodollar Loan by an amount deemed by such Lender to be
     material,

then such Lender shall promptly notify Agent and Borrower in writing of the
happening of such event and of the amount required to compensate such Lender for
such event (on an after-tax basis, taking into account any taxes on such
compensation), whereupon (i) Borrower shall pay such amount to Agent for the
account of such Lender and (ii) Borrower may elect, by giving to Agent and such
Lender not less than three Business Days' notice, to convert all (but not less
than all) of any such Eurodollar Loans into Base Rate Loans.

      Section 3.4.  Availability.  If (a) any change in applicable Laws, or in
                    ------------                                              
the interpretation or administration thereof of or in any jurisdiction
whatsoever, domestic or foreign, shall make it unlawful or impracticable for any
Lender to fund or maintain Eurodollar Loans, or shall materially restrict the
authority of any Lender to purchase or take offshore deposits of dollars (i.e.,
"eurodollars"), or (b) any Lender determines that matching deposits appropriate
to fund or maintain any Eurodollar Loan are not available to it, or (c) any
Lender determines that the formula for calculating the Eurodollar Rate does not
fairly reflect the cost to such Lender of making or maintaining loans based on
such rate, then, upon notice by such Lender to Borrower and Agent, Borrower's
right to elect Eurodollar Loans from such Lender shall be suspended to the
extent and for the duration of such illegality, impracticability or restriction
and all Eurodollar Loans of such Lender which are then outstanding or are then
the subject of any Borrowing Notice and which cannot lawfully or practicably be
maintained or funded shall immediately become or remain, or shall be funded as,
Base Rate Loans of such Lender.  Borrower agrees to indemnify each Lender and
hold it harmless against all costs, expenses, claims, penalties, liabilities and
damages which may result from any such change in Law, interpretation or
administration (other than taxes imposed on the overall net income of such
Lender or any lending office of such Lender).  Such indemnification shall be on
an after-tax basis, taking into account any taxes imposed on the amounts paid as
indemnity.

      Section 3.5.  Funding Losses.  In addition to its other obligations
                    --------------                                       
hereunder, Borrower will indemnify each Lender against, and reimburse each
Lender on demand for, any loss or expense incurred or sustained by such Lender
(including any loss or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by a Lender to fund or maintain
Eurodollar Loans), as a result of (a) any payment or prepayment (whether
authorized or required hereunder or otherwise) of all or a portion of a
Eurodollar Loan on a day other than the day on which the applicable Interest
Period ends, (b) any payment or prepayment, whether required hereunder or
otherwise, of a Loan made after the delivery, but before the effective date, of
a Continuation/ Conversion Notice, if such payment or prepayment prevents such
Continuation/Conversion Notice from becoming fully effective, (c) the failure of
any Loan to be made or of any Continuation/ Conversion Notice to become
effective due to any condition precedent not being satisfied or due to any other
action or inaction of any Related Person, or (d) any conversion (whether
authorized or required hereunder or otherwise) of all or any portion of any
Eurodollar Loan into a Base Rate Loan or into a different Eurodollar Loan on a
day other than the day on which the applicable Interest Period ends. Such
indemnification shall be on an after-tax basis, taking into account any taxes
imposed on the amounts paid as indemnity.

      Section 3.6.  Reimbursable Taxes.  Borrower covenants and agrees that:
                    ------------------                                      

          (a)  Borrower will indemnify each Lender against and reimburse each
     Lender for all present and future income, stamp and other taxes, levies,
     costs and charges whatsoever imposed, assessed, levied or collected on or
     in respect of this Agreement or any Eurodollar Loans (whether or not
     legally or correctly imposed, assessed, levied or collected), excluding,
     however, any taxes imposed on or measured by the overall net income of
     Agent or such Lender or any lending office of such Lender by any
     jurisdiction in which such Lender or any such lending office is located
     (all such non-excluded taxes, levies, costs and charges being collectively
     called "Reimbursable Taxes" in this section).  Such indemnification shall
     be on an after-tax basis, taking into account any taxes imposed on the
     amounts paid as indemnity.

          (b)  All payments on account of the principal of, and interest on,
     each Lender's Loans and Note, and all other amounts payable by Borrower to
     any Lender hereunder, shall be made in full without set-off or counterclaim
     and shall be made free and clear of and without deductions or withholdings
     of any nature by reason of any Reimbursable Taxes, all of which will be for
     the account of Borrower.  In the event of Borrower being compelled by Law
     to make any such deduction or withholding from any payment to any Lender,
     Borrower shall pay on the due date of such payment, by way of additional
     interest, such additional amounts as are needed to cause the amount
     receivable by such Lender after such deduction or withholding to equal the
     amount which would have been receivable in the absence of such deduction or
     withholding.  If Borrower should make any deduction or withholding as
     aforesaid, Borrower shall within 60 days thereafter forward to such Lender
     an official receipt or other official document evidencing payment of such
     deduction or withholding.

          (c)  If Borrower is ever required to pay any Reimbursable Tax with
     respect to any Eurodollar Loan, Borrower may elect, by giving to Agent and
     such Lender not less than three Business Days' notice, to convert all (but
     not less than all) of any such Eurodollar Loan into a Base Rate Loan, but
     such election shall not diminish Borrower's obligation to pay all
     Reimbursable Taxes.

          (d)  Notwithstanding the foregoing provisions of this section,
     Borrower shall be entitled, to the extent it is required to do so by Law,
     to deduct or withhold (and not to make any indemnification or reimbursement
     for) income or other similar taxes imposed by the United States of America
     (other than any portion thereof attributable to a change in federal income
     tax Laws effected after the date hereof) from interest, fees or other
     amounts payable hereunder for the account of any Lender, other than a
     Lender (i) who is a U.S. person for Federal income tax purposes or (ii) who
     has the Prescribed Forms on file with Agent (with copies provided to
     Borrower) for the applicable year to the extent deduction or withholding of
     such taxes is not required as a result of the filing of such Prescribed
     Forms, provided that if Borrower shall so deduct or withhold any such
     taxes, it shall provide a statement to Agent and such Lender, setting forth
     the amount of such taxes so deducted or withheld, the applicable rate and
     any other information or documentation which such Lender may reasonably
     request for assisting such Lender to obtain any allowable credits or
     deductions for the taxes so deducted or withheld in the jurisdiction or
     jurisdictions in which such Lender is subject to tax.  As used in this
     section, "Prescribed Forms" means such duly executed forms or statements,
     and in such

                                       14
<PAGE>
 
     number of copies, which may, from time to time, be prescribed by Law and
     which, pursuant to applicable provisions of (x) an income tax treaty
     between the United States and the country of residence of the Lender
     providing the forms or statements, (y) the Internal Revenue Code of 1986,
     as amended from time to time, or (z) any applicable rules or regulations
     thereunder, permit Borrower to make payments hereunder for the account of
     such Lender free of such deduction or withholding of income or similar
     taxes.

      Section 3.7.  Change of Applicable Lending Office.  Each Lender agrees
                    -----------------------------------                     
that, upon the occurrence of any event giving rise to the operation of Sections
3.2 through 3.6 with respect to such Lender, it will, if requested by Borrower,
use reasonable efforts (subject to overall policy considerations of such Lender)
to designate another Lending Office, provided that such designation is made on
such terms that such Lender and its Lending Office suffer no economic, legal or
regulatory disadvantage, with the object of avoiding the consequence of the
event giving rise to the operation of any such section.  Nothing in this section
shall affect or postpone any of the obligations of Borrower or the rights of any
Lender provided in Sections 3.2 through 3.6.

      Section 3.8.  Replacement of Banks.  If any Lender seeks reimbursement for
                    --------------------                                        
increased costs under Sections 3.2 through 3.6, then within ninety days
thereafter -- provided no Event of Default then exists -- Borrower shall have
the right (unless such Lender withdraws its request for additional compensation)
to replace such Lender by requiring such Lender to assign its Loans and Notes
and its commitments hereunder to an Eligible Transferee reasonably acceptable to
Agent and to Borrower, provided that: (i) all Obligations of Borrower owing to
such Lender being replaced (including such increased costs, but excluding
principal and accrued interest on the Notes being assigned) shall be paid in
full to such Lender concurrently with such assignment, and (ii) the replacement
Eligible Transferee shall purchase the Note being assigned by paying to such
Lender a price equal to the principal amount thereof plus accrued and unpaid
interest thereon.  In connection with any such assignment Borrower, Agent, such
Lender and the replacement Eligible Transferee shall otherwise comply with
Section 9.5. Notwithstanding the foregoing rights of Borrower under this
section, however, Borrower may not replace any Lender which seeks reimbursement
for increased costs under Section 3.2 through 3.6 unless Borrower is at the same
time replacing all Lenders which are then seeking such compensation.

in the Loan Documents, including Annex C, and  Borrower and Parent will cause
each other Related Person to observe, perform and comply with every such term,

      Section 6.2.  Agreement to Deliver Security Documents.  Parent and
                    ---------------------------------------             
Borrower agree to have any Subsidiary formed after the date hereof execute a
Guaranty for the benefit of the Lenders in form substantially similar to the
Parent Guaranty.  In addition, Parent and Borrower each agree to deliver and to
cause each other Related Person to deliver, to further secure the Obligations
whenever requested by Agent in its sole and absolute discretion, deeds of trust,
mortgages, chattel mortgages, security agreements, financing statements and
other Security Documents in form and substance satisfactory to Agent for the

stating that such Related Person has good and defensible title to such
properties and interests, free and clear of all Liens other than Permitted
Liens, (b) confirming that such properties and interests are subject to Security
Documents securing the Obligations that constitute and create legal, valid and
duly perfected first deed of trust or mortgage liens in such properties and

                    ---------------------                                 
Obligations Borrower and Parent each hereby grant to each Lender a security
interest, a lien, and a right of offset, each of which shall be in addition to
all other interests, liens, and rights of any Lender at common law, under the
Loan Documents, or otherwise, and each of which shall be upon and against (a)
any and all moneys, securities or other property (and the proceeds therefrom) of
Borrower or Parent now or hereafter held or received by or in transit to any
Lender from or for the account of Borrower or Parent, whether for safekeeping,
custody, pledge, transmission, collection or otherwise, (b) any and all deposits
(general or special, time or demand, provisional or final) of Borrower or Parent
with any Lender, and (c) any other credits and claims of Borrower or Parent at

each Lender is hereby authorized to foreclose upon, or to offset against the
Obligations then due and payable (in either case without notice to Borrower or
Parent), any and all items hereinabove referred to.  The remedies of foreclosure
and offset are separate and cumulative, and either may be exercised
independently of the other without regard to procedures or restrictions
applicable to the other.

      Section 6.5.  Guaranties of Parent's Subsidiaries.  Each Subsidiary of
                    -----------------------------------                     
Parent now existing or created, acquired or coming into existence after the date
hereof shall, promptly upon request by Agent, execute and deliver to Agent an
absolute and unconditional guaranty of the timely repayment of the Obligations
and the due and punctual performance of the obligations of Parent hereunder,

Subsidiary of Parent existing on the date hereof shall duly execute and deliver
such a guaranty prior to the making of any Loan hereunder.  Parent will cause

to the property covered thereby, so long as no Default has occurred Related
Persons may continue to receive from the purchasers of production all such
Production Proceeds, subject, however, to the Liens created under the Security
Documents, which Liens are hereby affirmed and ratified.  Upon the occurrence of
a Default, Agent and Banks may exercise all rights and remedies granted under
the Security Documents, including the right to obtain possession of all
Production Proceeds then held by Related Persons or to receive directly from the

                                       19
<PAGE>
 
purchasers of production all other Production Proceeds. In no case shall any
failure, whether purposed or inadvertent, by Agent or Banks to collect directly
any such Production Proceeds constitute in any way a waiver, remission or
release of any of their rights under the Security Documents, nor shall any
release of any Production Proceeds by Agent or Banks to Related Persons
constitute a waiver, remission, or release of any other Production Proceeds or
of any rights of Agent or Banks to collect other Production Proceeds thereafter.

      Section 6.7.  TCW Debt.  No Related Person will make any payment on or
                    --------

all of the Obligations shall thereupon be immediately due and payable, without
demand, presentment, notice of demand or of dishonor and nonpayment, protest,
notice of protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by Borrower and each Related Person who at any time
ratifies or approves this Agreement.  Upon any such acceleration, any obligation
of any Bank to make any further Loans shall be permanently terminated.  During
the continuance of any other Event of Default, Agent at any time and from time
to time may (and upon written instructions from Required Lenders, Agent shall),
without notice to Borrower or any other Related Person, do either or both of the
following:  (1) terminate any obligation of Banks to make Loans hereunder, and
(2) declare any or all of the Obligations immediately due and payable, and all
such Obligations shall thereupon be immediately due and payable, without demand,
presentment, notice of demand or of dishonor and nonpayment, protest, notice of
protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by Borrower and each Related Person who at any time
ratifies or approves this Agreement.

      Section 7.3.  Remedies.  If any Default shall occur and be continuing,
                    --------                                                
each Lender may protect and enforce its rights under the Loan Documents by any
appropriate proceedings, including proceedings for specific performance of any
covenant or agreement contained in any Loan Document, and each Lender may
enforce the payment of any Obligations due it or enforce any other legal or
equitable right which it may have.  All rights, remedies and powers conferred
upon Lenders under the Loan Documents shall be deemed cumulative and not
exclusive of any other rights, remedies or powers available under the Loan
Documents or at Law or in equity.

                             ARTICLE VIII - Agent
                                            -----

      Section 8.1.  Appointment and Authority.  Each Bank hereby irrevocably
                    -------------------------                               
authorizes Agent, and Agent hereby undertakes, to receive payments of principal,
interest and other amounts due hereunder as specified herein and to take all
other actions and to exercise such powers under the Loan Documents as are
specifically delegated to Agent by the terms hereof or thereof, together with
all other powers reasonably incidental thereto.  The relationship of Agent to
the other Banks is only that of one commercial Bank acting as administrative
agent for others, and nothing in the Loan Documents shall be

                                       20
<PAGE>
 
construed to constitute Agent a trustee or other fiduciary for any holder of any
of the Notes or of any participation therein nor to impose on Agent duties and
obligations other than those expressly provided for in the Loan Documents. With
respect to any matters not expressly provided for in the Loan Documents and any
matters which the Loan Documents place within the discretion of Agent, Agent
shall not be required to exercise any discretion or take any action, and it may
request instructions from Banks with respect to any such matter, in which case
it shall be required to act or to refrain from acting (and shall be fully
protected and free from liability to all Banks in so acting or refraining from
acting) upon the instructions of Required Lenders (including itself), provided,
however, that Agent shall not be required to take any action which exposes it to
a risk of personal liability that it considers unreasonable or which is contrary
to the Loan Documents or to applicable Law. Upon receipt by Agent from Borrower
of any communication calling for action on the part of Banks or upon notice from
any other Bank to Agent of any Default or Event of Default, Agent shall promptly
notify each other Bank thereof.

      Section 8.2.  Exculpation, Agent's Reliance, Etc.  Neither Agent nor any
                    ----------------------------------                        
of its directors, officers, agents, attorneys, or employees shall be liable for
any action taken or omitted to be taken by any of them under or in connection
with the Loan Documents, INCLUDING THEIR NEGLIGENCE OF ANY KIND, except that
each shall be liable for its own gross negligence or willful misconduct. Without
limiting the generality of the foregoing, Agent (a) may treat the payee of any
Note as the holder thereof until Agent receives written notice of the assignment
or transfer thereof in accordance with this Agreement, signed by such payee and
in form satisfactory to Agent; (b) may consult with legal counsel (including
counsel for Borrower), independent public accountants and other experts selected
by it and shall not be liable for any action taken or omitted to be taken in
good faith by it in accordance with the advice of such counsel, accountants or
experts; (c) makes no warranty or representation to any other Bank and shall not
be responsible to any other Bank for any statements, warranties or
representations made in or in connection with the Loan Documents; (d) shall not
have any duty to ascertain or to inquire as to the performance or observance of
any of the terms, covenants or conditions of the Loan Documents on the part of
any Related Person or to inspect the property (including the books and records)
of any Related Person; (e) shall not be responsible to any other Bank for the
due execution, legality, validity, enforceability, genuineness, sufficiency or
value of any Loan Document or any instrument or document furnished in connection
therewith; (f) may rely upon the representations and warranties of each Related
Person and the Banks in exercising its powers hereunder; and (g) shall incur no
liability under or in respect of the Loan Documents by acting upon any notice,
consent, certificate or other instrument or writing (including any telecopy,
telegram, cable or telex) believed by it to be genuine and signed or sent by the
proper Person or Persons.

      Section 8.3.  Credit Decisions.  Each Bank acknowledges that it has,
                    ----------------                                      
independently and without reliance upon any other Bank, made its own analysis of
Borrower and the transactions contemplated hereby and its own independent
decision to enter into this Agreement and the other Loan Documents. Each Bank
also acknowledges that it will, independently and without reliance upon any
other Bank and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under the Loan Documents.

      Section 8.4.  Indemnification.  Each Bank agrees to indemnify Agent (to
                    ---------------                                          
the extent not reimbursed by Borrower within ten (10) days after demand) from
and against such Bank's Percentage Share of any and all liabilities,
obligations, claims, losses, damages, penalties, fines, actions, judgments,
suits, settlements, costs, expenses or disbursements (including reasonable fees
of attorneys, accountants, experts and advisors) of any kind or nature
whatsoever (in this section collectively called "liabilities and costs") which
to any extent (in whole or in part) may be imposed on, incurred by, or

                                       21
<PAGE>
 
asserted against Agent growing out of, resulting from or in any other way
associated with any of the Collateral, the Loan Documents and the transactions
and events (including the enforcement thereof) at any time associated therewith
or contemplated therein (including any violation or noncompliance with any
Environmental Laws by any Person or any liabilities or duties of any Person with
respect to Hazardous Materials found in or released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT,

provided only that no Bank shall be obligated under this section to indemnify
Agent for that portion, if any, of any liabilities and costs which is
proximately caused by Agent's own individual gross negligence or willful
misconduct, as determined in a final judgment.  Cumulative of the foregoing,
each Bank agrees to reimburse Agent promptly upon demand for such Bank's
Percentage Share of any costs and expenses to be paid to Agent by Borrower under
Section 9.4(a) to the extent that Agent is not timely reimbursed for such
expenses by Borrower as provided in such section.  As used in this section the
term "Agent" shall refer not only to the Person designated as such in Section
1.1 but also to each director, officer, agent, attorney, employee,
representative and Affiliate of such Person.

      Section 8.5.  Rights as Bank.  In its capacity as a Bank, Agent shall have
                    --------------                                              
the same rights and obligations as any Bank and may exercise such rights as
though it were not Agent.  Agent may accept deposits from, lend money to, act as
Trustee under indentures of, and generally engage in any kind of business with
any Related Person or their Affiliates, all as if it were not Agent hereunder
and without any duty to account therefor to any other Bank.

      Section 8.6.  Sharing of Set-Offs and Other Payments.  Each Bank agrees
                    --------------------------------------                   
that if it shall, whether through the exercise of rights under Security
Documents or rights of banker's lien, set off, or counterclaim against Borrower
or otherwise, obtain payment of a portion of the aggregate Obligations owed to
it which, taking into account all distributions made by Agent under Section 3.1,
causes such Bank to have received more than it would have received had such
payment been received by Agent and distributed pursuant to Section 3.1, then (a)
it shall be deemed to have simultaneously purchased and shall be obligated to
purchase interests in the Obligations as necessary to cause all Banks to share
all payments as provided for in Section 3.1, and (b) such other adjustments
shall be made from time to time as shall be equitable to ensure that Agent and
all Banks share all payments of Obligations as provided in Section 3.1;
provided, however, that nothing herein contained shall in any way affect the
right of any Bank to obtain payment (whether by exercise of rights of banker's
lien, set-off or counterclaim or otherwise) of indebtedness other than the
Obligations.  Borrower expressly consents to the foregoing arrangements and
agrees that any holder of any such interest or other participation in the
Obligations, whether or not acquired pursuant to the foregoing arrangements, may
to the fullest extent permitted by Law exercise any and all rights of banker's
lien, set-off, or counterclaim as fully as if such holder were a holder of the
Obligations in the amount of such interest or other participation.  If all or
any part of any funds transferred pursuant to this section is thereafter
recovered from the seller under this section which received the same, the
purchase provided for in this section shall be deemed to have been rescinded to
the extent of such recovery, together with interest, if any, if interest is
required pursuant to Tribunal order to be paid on account of the possession of
such funds prior to such recovery.

      Section 8.7.  Investments.  Whenever Agent in good faith determines that
                    -----------                                               
it is uncertain about how to distribute to Banks any funds which it has
received, or whenever Agent in good faith

                                       22
<PAGE>
 
determines that there is any dispute among Banks about how such funds should be
distributed, Agent may choose to defer distribution of the funds which are the
subject of such uncertainty or dispute. If Agent in good faith believes that the
uncertainty or dispute will not be promptly resolved, or if Agent is otherwise
required to invest funds pending distribution to Banks, Agent shall invest such
funds pending distribution; all interest on any such investment shall be
distributed upon the distribution of such investment and in the same proportion
and to the same Persons as such investment. All moneys received by Agent for
distribution to Banks (other than to the Person who is Agent in its separate
capacity as a Bank) shall be held by Agent pending such distribution solely as
Agent for such Banks, and Agent shall have no equitable title to any portion
thereof.

      Section 8.8.  Benefit of Article VIII.  The provisions of this Article
                    -----------------------                                 
(other than the following Section 8.9) are intended solely for the benefit of
Banks, and no Related Person shall be entitled to rely on any such provision or
assert any such provision in a claim or defense against any Bank.  Banks may
waive or amend such provisions as they desire without any notice to or consent
of Borrower or any Related Person.

      Section 8.9.  Resignation.  Agent may resign at any time by giving written
                    -----------                                                 
notice thereof to Banks and Borrower.  Each such notice shall set forth the date
of such resignation.  Upon any such resignation, Required Banks shall have the
right to appoint a successor Agent.  A successor must be appointed for any
retiring Agent, and such Agent's resignation shall become effective when such
successor accepts such appointment.  If, within thirty days after the date of
the retiring Agent's resignation, no successor Agent has been appointed and has
accepted such appointment, then the retiring Agent may appoint a successor
Agent, which shall be a commercial bank organized or licensed to conduct a
banking or trust business under the Laws of the United States of America or of
any state thereof.  Upon the acceptance of any appointment as Agent hereunder by
a successor Agent, the retiring Agent shall be discharged from its duties and
obligations under this Agreement and the other Loan Documents.  After any
retiring Agent's resignation hereunder the provisions of this Article VIII shall
continue to inure to its benefit as to any actions taken or omitted to be taken
by it while it was Agent under the Loan Documents.

                          ARTICLE IX - Miscellaneous
                                       -------------

            Section 9.1.  Waivers and Amendments; Acknowledgements.
                          ---------------------------------------- 

     (a)  Waivers and Amendments.  No failure or delay (whether by course of
          ----------------------                                            
conduct or otherwise) by any Lender in exercising any right, power or remedy
which such Lender may have under any of the Loan Documents shall operate as a
waiver thereof or of any other right, power or remedy, nor shall any single or
partial exercise by any Lender of any such right, power or remedy preclude any
other or further exercise thereof or of any other right, power or remedy.  No
waiver of any provision of any Loan Document and no consent to any departure
therefrom shall ever be effective unless it is in writing and signed as provided
below in this section, and then such waiver or consent shall be effective only
in the specific instances and for the purposes for which given and to the extent
specified in such writing.  No notice to or demand on any Related Person shall
in any case of itself entitle any Related Person to any other or further notice
or demand in similar or other circumstances.  This Agreement and the other Loan
Documents set forth the entire understanding between the parties hereto with
respect to the transactions contemplated herein and therein and supersede all
prior discussions and understandings with respect to the subject matter hereof
and thereof, and no waiver, consent, release, modification or amendment of or
supplement to this Agreement or the other Loan Documents shall be valid or
effective against any party hereto unless the same is in writing and signed by
(i) if such party is Borrower, by Borrower, (ii) if such party is Agent, by such
party, and (iii) if such party is a Bank, by such Bank or

                                       23
<PAGE>
 
by Agent on behalf of Banks with the written consent of Required Lenders (which
consent has already been given as to the termination of the Loan Documents as
provided in Section 9.9). Notwithstanding the foregoing or anything to the
contrary herein, Agent shall not, without the prior consent of each individual
Bank, execute and deliver on behalf of such Bank any waiver or amendment which
would: (1) waive any of the conditions specified in Article IV (provided that
Agent may in its discretion withdraw any request it has made under Section
4.3(e)), (2) reduce any fees payable to such Bank hereunder, or the principal
of, or interest on, such Bank's Note, (3) postpone any date fixed for any
payment of any such fees, principal or interest, (4) amend the definition herein
of "Required Lenders" or otherwise change the aggregate amount of Percentage
Shares which is required for Agent, Banks or any of them to take any particular
action under the Loan Documents, (5) release Borrower from its obligation to pay
such Bank's Note or any Guarantor from its guaranty of such payment, or (7)
amend any provision of the Intercreditor Agreement.

     (b)  Acknowledgements and Admissions.  Borrower hereby represents,
          -------------------------------                              
warrants, acknowledges and admits that (i) it has been advised by counsel in the
negotiation, execution and delivery of the Loan Documents to which it is a
party, (ii) it has made an independent decision to enter into this Agreement and
the other Loan Documents to which it is a party, without reliance on any
representation, warranty, covenant or undertaking by Agent or any Bank, whether
written, oral or implicit, other than as expressly set out in this Agreement or
in another Loan Document delivered on or after the date hereof, (iii) there are
no representations, warranties, covenants, undertakings or agreements by any
Lender as to the Loan Documents except as expressly set out in this Agreement or
in another Loan Document delivered on or after the date hereof, (iv) no Lender
has any fiduciary obligation toward Borrower with respect to any Loan Document
or the transactions contemplated thereby, (v) the relationship pursuant to the
Loan Documents between Borrower and the other Related Persons, on one hand, and
each Lender, on the other hand, is and shall be solely that of debtor and
creditor, respectively, (vi) no partnership or joint venture exists with respect
to the Loan Documents between any Related Person and any Lender, (vii) Agent is
not Borrower's Agent, but Agent for Banks, (viii) should an Event of Default or
Default occur or exist, each Lender will determine in its sole discretion and
for its own reasons what remedies and actions it will or will not exercise or
take at that time, (ix) without limiting any of the foregoing, Borrower is not
relying upon any representation or covenant by any Lender, or any representative
thereof, and no such representation or covenant has been made, that any Lender
will, at the time of an Event of Default or Default, or at any other time,
waive, negotiate, discuss, or take or refrain from taking any action permitted
under the Loan Documents with respect to any such Event of Default or Default or
any other provision of the Loan Documents, and (x) all Lenders have relied upon
the truthfulness of the acknowledgements in this section in deciding to execute
and deliver this Agreement and to become obligated hereunder.

     (c)  Representation by Banks.  Each Bank hereby represents that it will
          -----------------------                                           
acquire its Note for its own account in the ordinary course of its commercial
lending business; however, the disposition of such Bank's property shall at all
times be and remain within its control and, in particular and without
limitation, such Bank may sell or otherwise transfer its Note, any participation
interest or other interest in its Note, or any of its other rights and
obligations under the Loan Documents.

     (d)  Joint Acknowledgment.  THIS WRITTEN AGREEMENT AND THE OTHER LOAN
          --------------------                                            
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

     THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

      Section 9.2.  Survival of Agreements; Cumulative Nature.  All of Related
                    -----------------------------------------                 
Persons' various representations, warranties, covenants and agreements in the
Loan Documents shall survive the execution and delivery of this Agreement and
the other Loan Documents and the performance hereof and thereof, including the
making or granting  of the Loans and the  delivery of the Notes and the other
Loan Documents, and shall further survive until all of the Obligations are paid
in full to each Lender and all of Lenders' obligations to Borrower are
terminated.  All statements and agreements contained in any certificate or other
instrument delivered by any Related Person to any Lender under any Loan Document
shall be deemed representations and warranties by Borrower or agreements and
covenants of Borrower under this Agreement.  The representations, warranties,
indemnities, and covenants made by Related Persons in the Loan Documents, and
the rights, powers, and privileges granted to Lenders in the Loan Documents, are
cumulative, and, except for expressly specified waivers and consents, no Loan
Document shall be construed in the context of another to diminish, nullify, or
otherwise reduce the benefit to any Lender of any such representation, warranty,
indemnity, covenant, right, power or privilege.  In particular and without
limitation, no exception set out in this Agreement to any representation,
warranty, indemnity, or covenant herein contained shall apply to any similar
representation, warranty, indemnity, or covenant contained in any other Loan
Document, and each such similar representation, warranty, indemnity, or covenant
shall be subject only to those exceptions which are expressly made applicable to
it by the terms of the various Loan Documents.

      Section 9.3.  Notices.  All notices, requests, consents, demands and other
                    -------                                                     
communications required or permitted under any Loan Document shall be in
writing, unless otherwise specifically provided in such Loan Document (provided
that Agent may give telephonic notices to the other Lenders), and shall be
deemed sufficiently given or furnished if delivered by personal delivery, by
telecopy or telex, by delivery service with proof of delivery, or by registered
or certified United States mail, postage prepaid, to Borrower and Related
Persons at the address of Borrower specified on the signature pages hereto and
to each Lender at its address specified on the signature pages hereto (unless
changed by similar notice in writing given by the particular Person whose
address is to be changed). Any such notice or communication shall be deemed to
have been given (a) in the case of personal delivery or delivery service, as of
the date of first attempted delivery during normal business hours at the address
provided herein, (b) in the case of telecopy or telex, upon receipt, or (c) in
the case of registered or certified United States mail, three days after deposit
in the mail; provided, however, that no Borrowing Notice shall become effective
until actually received by Agent.

      Section 9.4.  Payment of Expenses; Indemnity.
                    ------------------------------ 

     (a)  Payment of Expenses.  Whether or not the transactions contemplated by
          -------------------                                                  
this Agreement are consummated, Borrower will promptly (and in any event, within
30 days after any invoice or other statement or notice) pay: (i) all transfer,
stamp, mortgage, documentary or other similar taxes, assessments or charges
levied by any governmental or revenue authority in respect of this Agreement or
any of the other Loan Documents or any other document referred to herein or
therein, (ii) all reasonable costs and expenses incurred by or on behalf of
Agent (including attorneys' fees, consultants' fees and engineering fees, travel
costs and miscellaneous expenses) in connection with (1) the negotiation,
preparation, execution and delivery of the Loan Documents, and any and all
consents, waivers or other documents or instruments relating thereto, (2) the
filing, recording, refiling and re-recording of any Loan Documents and any other
documents or instruments or further assurances required to be filed or recorded
or refiled or re-recorded by the terms of any Loan Document, (3) the borrowings
hereunder and other action reasonably required in the course of administration
hereof, (4) monitoring or confirming (or preparation or negotiation of any
document related to) Borrower's compliance with any covenants or conditions
contained in this Agreement or in any Loan Document, and (iii) all reasonable
costs and expenses incurred by or on behalf of any Lender (including attorneys'

                                       25
<PAGE>
 
fees, consultants' fees and accounting fees) in connection with the defense or
enforcement of any of the Loan Documents (including this section) or the defense
of any Lender's exercise of its rights thereunder. In addition to the foregoing,
until and all Obligations have been paid in full, Borrower will also pay or
reimburse Agent for all reasonable out-of-pocket costs and expenses of Agent or
its agents or employees in connection with the continuing administration of the
Loans and the related due diligence of Agent, including travel and miscellaneous
expenses and fees and expenses of Agent's outside counsel, reserve engineers and
consultants engaged in connection with the Loan Documents.

     (b)  Indemnity.  Borrower and Parent each agree to indemnify each Lender,
          ---------                                                           
upon demand, from and against any and all liabilities, obligations, claims,
losses, damages, penalties, fines, actions, judgments, suits, settlements,
costs, expenses or disbursements (including reasonable fees of attorneys,
accountants, experts and advisors) of any kind or nature whatsoever (in this
section collectively called "liabilities and costs") which to any extent (in
whole or in part) may be imposed on, incurred by, or asserted against such
Lender growing out of, resulting from or in any other way associated with any of
the Collateral, the Loan Documents and the transactions and events (including
the enforcement or defense thereof) at any time associated therewith or
contemplated therein (including any violation or noncompliance with any
Environmental Laws by any Related Person or any liabilities or duties of any
Related Person or any Lender with respect to Hazardous Materials found in or
released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER,

provided only that no Lender shall be entitled under this section to receive
indemnification for that portion, if any, of any liabilities and costs which is
proximately caused by its own individual gross negligence or willful misconduct,
as determined in a final judgment.  If any Person (including Borrower or any of
its Affiliates) ever alleges such gross negligence or willful misconduct by any
Lender, the indemnification provided for in this section shall nonetheless be
paid upon demand, subject to later adjustment or reimbursement, until such time
as a court of competent jurisdiction enters a final judgment as to the extent
and effect of the alleged gross negligence or willful misconduct.  As used in
this section the term "Lenders" shall refer not only to the Persons designated
as such in Section 1.1 but also to each director, officer, agent, attorney,
employee, representative and Affiliate of such Persons.

      Section 9.5.  Joint and Several Liability; Parties in Interest;
                    -------------------------------------------------
Assignments.
- ----------- 

     (a)  All Obligations which are incurred by two or more Related Persons
shall be their joint and several obligations and liabilities.  All grants,
covenants and agreements contained in the Loan Documents shall bind and inure to
the benefit of the parties thereto and their respective successors and assigns;
provided, however, that no Related Person may assign or transfer any of its
rights or delegate any of its duties or obligations under any Loan Document
without the prior consent of Required Lenders.  Neither Borrower nor any
Affiliates of Borrower shall directly or indirectly purchase or otherwise retire
any Obligations owed to any Bank nor will any Bank accept any offer to do so,
unless each Bank shall have received substantially the same offer with respect
to the same Percentage Share of the Obligations owed to it.  If Borrower or any
Affiliate of Borrower at any time purchases some but less than all of the
Obligations owed to all Lenders, such purchaser shall not be entitled to any
rights of any Lender under the Loan Documents unless and until Borrower or its
Affiliates have purchased all of the Obligations.

                                       26
<PAGE>
 
     (b)  No Bank shall sell any participation interest in its commitment
hereunder or any of its rights under its Loans or under the Loan Documents to
any Person other than an Eligible Transferee, and then only if the agreement
between such Bank and such participant at all times provides: (i) that such
participation exists only as a result of the agreement between such participant
and such Bank and that such transfer does not give such participant any right to
vote as a Bank or any other direct claims or rights against any Person other
than such Bank, (ii) that such participant is not entitled to payment from any
Related Person under Sections 3.2 through 3.6 of amounts in excess of those
payable to such Bank under such sections (determined without regard to the sale
of such participation), and (iii) unless such participant is an Affiliate of
such Bank, that such participant shall not be entitled to require such Bank to
take any action under any Loan Document or to obtain the consent of such
participant prior to taking any action under any Loan Document, except for
actions which would require the consent of all Banks under subsection (a) of
Section 9.1.  No Bank selling such a participation shall, as between the other
parties hereto and such Bank, be relieved of any of its obligations hereunder as
a result of the sale of such participation.  Each Bank which sells any such
participation to any Person (other than an Affiliate of such Bank) shall give

     and a processing fee payable to Agent of $2,500.  Upon such execution,
     delivery, and payment and upon the satisfaction of the conditions set out

     (ii) as of the "Settlement Date" specified in such Assignment and
     Assumption the assignee thereunder shall be a party hereto and a Bank
     hereunder and Agent shall thereupon deliver to Borrower and each Bank a
     schedule showing the revised Percentage Shares of such assignor Bank and
     such assignee Bank and the Percentage Shares of all other Banks.

     1986, as amended) for Federal income tax purposes, shall (to the extent it
     has not already done so) provide Agent and Borrower with the "Prescribed
     Forms" referred to in Section 3.6(d).

from assigning or pledging all or any portion of its Loans and Note to any
Federal Reserve Bank as collateral security pursuant to Regulation A of the
Board of Governors of the Federal Reserve System and any Operating Circular
issued by such Federal Reserve Bank; provided that no such assignment or pledge
shall relieve such Bank from its obligations hereunder.

assignee Bank thereunder will be confirming to and agreeing with Borrower,
Agents and each other Bank hereunder that such assignee understands and agrees
to the terms hereof, including Article IX hereof.

register for the recordation of the names and addresses of Banks and the
Percentage Shares of, and principal amount of the Loans owing to, each Bank from
time to time (in this section called the "Register").  The entries in the
Register shall be conclusive, in the absence of manifest error, and Borrower and
each Lender may treat each Person whose name is recorded in the Register as a
Bank hereunder for all purposes.  The Register shall be available for inspection
by Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

          (d)  By March 1 following the end of each Fiscal Year, beginning on
     March 1, 1998, an engineering report prepared as of the end of such Fiscal
     Year by Ryder Scott Company or other independent petroleum engineers chosen
     by Borrower and acceptable to Required Lenders, concerning the Properties.
     The report (1) shall separately report on Proved Producing Reserves, Proved
     Developed Nonproducing Reserves, Proved Undeveloped Reserves and probable
     reserves and separately calculate the NPV of each such category of Proved
     Reserves (and the similar net present value of such probable reserves), (2)
     shall be prepared in two versions, the first using ING Pricing and the
     second using TCW Pricing, and each using a 10% discount factor, (3) shall
     address the various factors to be taken into account in calculating ANCF so
     that projected ANCF can be readily calculated from the report, (4) shall
     take into account Borrower's actual experiences with leasehold operating
     expenses and other costs in determining projected leasehold operating
     expenses and other costs, (5) shall identify and take into account any

     otherwise be in form and substance satisfactory to Required Lenders.  The
     report shall distinguish (or shall be delivered together with a certificate
     from an appropriate officer of Borrower which distinguishes) those
     Properties treated in the report which are Eligible Mortgaged Properties
     from those properties treated in the report which are not Eligible
     Mortgaged Properties.  In the event that Borrower and Tamco disagree over
     whether or not any workovers or other remedial capital expenditures should
     be included in the report for the purposes of calculating NPV, the
     engineers preparing such report shall resolve such disagreement by
     determining whether such expenditures are likely to be required in
     accordance with prudent industry practice and shall include or exclude such
     expenditures based on such determination.

          (e)  By July 15 of each year an engineering report prepared by in-
     house petroleum engineers employed by Borrower, concerning all oil and gas
     properties and interests owned by any Related Person which are located in
     or offshore of the United States and which have attributable to them proved
     oil and gas reserves.  This report shall be substantially in the form and
     substance as the reports delivered under subsection (d) above and otherwise
     shall be satisfactory to Required Lenders.

          (f)  Within fifty (50) days after the end of each Fiscal Quarter, a
     report in detail acceptable to Required Lenders with respect to the
     Properties during the Fiscal Quarter immediately prior thereto:

          natural gas liquids, and water produced (and the quantities of water
          injected) during such Fiscal Quarter;

               (2)  describing by well and field the quantities of oil, gas and
          natural gas liquids sold during such Fiscal Quarter out of production
          from the Properties and calculating the average sales prices of such
          oil, natural gas, and natural gas liquids;

               (3)  regardless of whether the same are included in the
          calculation of ANCF, specifying any leasehold operating expenses,
          overhead charges, gathering costs, transportation costs, and other
          costs with respect to the Properties of the kind chargeable as direct
          charges or overhead under an Onshore COPAS Accounting Procedure for
          Joint Operations (1984 form published by the Council of Petroleum
          Accountants Societies);

          Quarter in furtherance of the Plan of Development, all other capital
          expenditures during such Fiscal Quarter, and all projections of
          capital expenditures projected to be made on any of the Eligible
          Mortgaged Properties; and

               (6)  describing all workover work and drilling during such Fiscal
          Quarter, including the cost and status of each well drilled or worked
          over during such Fiscal Quarter, test reports for each well tested
          during such Fiscal Quarter, reports on prices and volumes received for
          such Fiscal Quarter, reports for each well completed during such
          Fiscal Quarter, and accompanying authorizations for expenditures.

     written report, as specified by Agent, based upon such review at Borrower's
     cost and expense.

          (i)  Concurrently with the annual renewal of the Borrower's insurance
     policies, Borrower shall, if requested by Agent in writing, cause a
     certificate or report to be issued by Agent's professional insurance
     consultants or other insurance consultants satisfactory to Agent certifying

     other day shall also be a Base Rate Payment Date.

          "Eurodollar Rate Payment Date" means, with respect to any Eurodollar

hereof, Noteholder agrees to make one advance to Borrower (the "ADVANCE"), the
amount of which Advance shall not exceed the Maximum Loan Amount.  The
obligation of Borrower to repay the aggregate amount of the Advance made by

therewith, shall be evidenced by two (2) promissory notes, one in the original
principal amount of $65,000,000 (the "A NOTE") and one in the original principal

principal or interest) from time to time outstanding shall bear interest on each
day outstanding at the rate of nine and three quarters percent (9.75%) per
annum, payable quarterly on each Quarterly Payment Date, calculated as of the
last day of the Fiscal Quarter then ending. All principal and interest owed
under the Notes and which has not been paid when due shall bear interest on each
day outstanding at the Late Payment Rate in effect on such day, and such
interest shall be due and payable daily as it accrues.

Borrower in immediately available funds at such account and bank as Borrower may
specify with such Request for Advance.

                        ---------------                                        
Advance to (i) make the Equitable Acquisition and to pay its costs related to
the Equitable Acquisition; (ii) to provide Borrower working capital (or to pay
down the Bank Debt); and (iii) to pay the costs and expenses related to the Bank
Debt and the Loan.  In no event shall the funds from any Advance be used
directly or indirectly by any Person for personal, family, household or
agricultural purposes or for the purpose, whether immediate, incidental or
ultimate, of purchasing, acquiring or carrying any "margin stock" or any "margin
securities" (as such terms are defined respectively in Regulation U and
Regulation G promulgated by the Board of Governors of the Federal Reserve
System) or to extend credit to others directly or indirectly for the purpose of
purchasing or carrying any such margin stock or margin securities.  Borrower

credit to others for the purpose of purchasing or carrying such margin stock or
margin securities.

outstanding principal balance of the Loan in an amount equal to the greater of:
(i) ninety percent (90%) of ANCF (less the interest payments made on the Notes
on such Quarterly Payment Date pursuant to Section 2.1 hereof); or (ii) in the

          (a)   Schedule 4 sets forth the amounts and dates for payment of all
principal payments of Allowed Bank Indebtedness which are required under the
Bank Documents (the "SCHEDULED BANK PAYMENTS").  All parties hereto acknowledge
and agree that, on or before the Quarterly Payment Date following each
Calculation Quarter, all ANCF with respect to such Calculation Quarter (and any

          (b)  Together with each payment made pursuant to this Section 2.6,
                                                                ----------- 
Borrower shall deliver to Noteholder a report in detail acceptable to Noteholder
setting out a detailed calculation of the ANCF for such Calculation Quarter.
Any principal payments made out of ANCF pursuant to this Section 2.6 will be

applicable Quarterly Payment Date, but the minimum principal payments required
under Section 2.5 will be required regardless of the amount of the payments

based on ANCF which are required under this Section 2.6.
                                            -----------  

          (c)  So long as no Event of Default has occurred and is then
continuing, Noteholder shall first apply all principal payments on the Loan made
pursuant to the preceding subsection (b) to the payment of any minimum principal
payment then required under Section 2.5 and shall then apply any remaining
                            -----------                                   
payments made pursuant to this section to the prepayment, without premium or
penalty, of the principal payments thereafter required under Section 2.5 in the

inverse order of their maturity.

          (d)  If any Event of Default has occurred and is continuing, and if no
Bank Debt is then outstanding, then Noteholder may in its sole and absolute
discretion apply the ANCF as it elects to the various Obligations which are then
due and payable.

          Section 2.7.  Optional Prepayments in Whole.  In addition to the
                        -----------------------------                     
payments required under Sections 2.5 and 2.6, Borrower may, at any time after
                        ------------     ---                                 
October 1, 1999 and after Borrower has given at least forty-five (45) days
advance notice to Noteholder, from time to time and without premium or penalty
prepay the Notes, in whole but not in part.  Any prepayment of principal made
under this section shall be accompanied by all interest then accrued and unpaid
on the principal so prepaid. Prior to October 1, 1999, Borrower may not prepay
any principal of the Notes without the prior written consent of the Required
Lenders, which consent may be given or withheld in their sole and absolute
discretion.

prepayments, or otherwise) or, if earlier, upon the acceleration of the A Note,
Noteholder shall be entitled to receive additional payment (the "ADDITIONAL
INTEREST") in cash in the amount required to give Noteholder a 12.5% IRR on the
entire amount of the Loan Document Disbursements with respect to the A Note, and
Borrower shall be obligated to pay the Additional Interest (it being understood
and agreed that the Additional Interest is in addition to the principal and
stated interest owing on the Loan, represents deferred compensation for the
making and commitment to make the Loan, and in no way constitutes a penalty).

          Section 2.9.  General Payment Provisions.  Borrower will make each
                        --------------------------                          
payment which it owes under the Loan Documents such that payment is received by

such payment becomes due and payable, in lawful money of the United States of

specify).  Any payment received by Noteholder after such time will be deemed to
have been made on the next following Business Day.  Should any such payment
become due and payable on a day other than a Business Day, the maturity of such
payment shall be extended to the next succeeding Business Day, and, in the case
of a payment of principal or past due interest, interest shall accrue and be
payable thereon for the period of such extension as provided in the Loan
Document under which such payment is due.  Each payment under a Loan Document
shall be due and payable at the place provided therein and, if no specific place
of payment is provided, shall be due and payable at the place of payment of the
Note.  When Noteholder collects or 

                                     - 15 -

receives money on account of the Obligations which is insufficient to pay all
Obligations then due and payable, Noteholder may apply such money as it elects
to the various Obligations which are then due and payable.

Ratio of 125% or less at any time is herein called a "COVERAGE DEFAULT", and a
Coverage Ratio of more than 125% but less than 150% at any time is herein called
a "COVERAGE DEFICIENCY".  If any Coverage Default exists, Borrower must (or if
any Coverage Deficiency exists, Borrower may in its discretion in order to avoid
a 100% Quarter), within thirty (30) days after obtaining knowledge thereof, cure
such Coverage Default (or Coverage Deficiency), either by furnishing and
mortgaging additional engineered producing oil and gas properties satisfactory
to Noteholder in order to increase Modified NPV or by making payments in order
to reduce the Adjusted Investment; provided that Borrower may not cure more than
two (2) Coverage Defaults by mortgaging additional engineered producing oil and
gas properties.

          (b) As used in this section, "COVERAGE RATIO" means at any time in
question the quotient obtained by dividing:

          (i) the sum of (A) 100% of the Modified NPV as determined from the
     Engineering Report most recently prepared as of such time in question, (B)
     the Lease Value Amount (as defined below) and (C) Working Capital,

          (ii) by the "ADJUSTED INVESTMENT" at such time.

For purposes of this Section 5.2, the term "LEASE VALUE AMOUNT" means (a) until
                     -----------

ending on June 30, 1999, the working interest of Borrower in each Unevaluated
Property multiplied by $150 per acre, (c) during the period beginning July 1,
1999 and ending on June 30, 2000, the working interest of Borrower in each
Unevaluated Property multiplied by $50 per acre, and (d) at all times after June
30, 2000, zero.

Documents, subject to the provisions of the Bank Documents and Intercreditor
Agreement, including the right to obtain possession of all Production Proceeds
then held by Borrower or Parent and to receive directly from the purchasers of
production all other Production Proceeds.  In no case shall any failure, whether
purposed or inadvertent, by Collateral Agent to collect directly any such
Production Proceeds constitute in any way a waiver, remission or release of any
of its rights under the Security Documents, nor shall any release of any
Production Proceeds by Collateral Agent to Borrower or Parent constitute a
waiver, remission, or release of any other Production Proceeds or of any rights
of Collateral Agent to collect other Production Proceeds thereafter.

of Noteholder in (i) exercising rights and remedies with respect to Collateral
(which may be delegated to Collateral Agent) or with respect to any other matter
under any of the Loan Documents, (ii) giving notices or instructions to
Borrower, (iii) receiving information from or notices by Borrower, and (iv)

this Agreement or any other Loan Document. Agent may, on behalf of Noteholder,
take any other action which Noteholder is entitled to take hereunder or under
any of the Loan Documents. Borrower and Parent may rely on any action of Agent
as binding upon Noteholder. Such appointment of Tamco as Agent shall not,
however, impair or modify any rights, obligations or duties which Tamco or any
Affiliate of Tamco otherwise has with respect to Noteholder. In its
administration of this Agreement and the other Loan Documents, except to the
extent to which another standard applies to Tamco by reason of any other
document between Tamco and Noteholder, Agent will exercise the same care that it
exercises in the administration or handling of transactions for its own account,
subject, however, to subsection (g) below.

taking, holding and disposing of the Collateral.  Tamco hereby accepts such
appointment.  Collateral Agent shall act for and on behalf of Noteholder in
connection with all Collateral and all Security Documents, including serving as
mortgagee under each Mortgage and exercising rights and remedies provided

release Collateral in accordance with the terms thereof and Collateral Agent is
hereby authorized to do so if it has received the prior consent of Noteholder,
it being understood that Noteholder itself need not be a party to any such
release. In its administration of this Agreement and the other Loan Documents,
except to the extent to which another standard applies to Tamco by reason of any
other document between Tamco and Noteholder, Collateral Agent will exercise the
same care that it exercises in the administration or handling of transactions
for its own account, subject, however, to subsection (g) below.

Agreement or the other Loan Documents against Agent or Collateral Agent.

interpretation of this Agreement, the Note and the other Loan Documents, or (ii)
any action to be taken or not to be taken hereunder or thereunder, and may
withhold any action until such directions have been received from the
Noteholder. Agent and Collateral Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement in accordance with a
direction of Noteholder under the terms of this Agreement.

          (ii)  be responsible in any manner to Noteholder or any other Person
     for any failure of any other party to perform its obligations under this
     Agreement, the Note or any other Loan Document.

Nothing in this subsection, however, shall be deemed to limit or restrict any
liability, fiduciary duty or responsibility of Tamco in any capacity other than
as Agent or Collateral Agent, respectively, including any liability, fiduciary
duty or responsibility under the Noteholder Governing Documents.

          (g) Reliance upon Documentation.  Each of Agent and Collateral Agent

of a successor Agent by Noteholder, Borrower and Parent shall not be required to
recognize any such removal or appointment unless and until Borrower and Parent
shall have received a writing setting forth such removal and appointment
executed by Noteholder, and Borrower and Parent shall be entitled to rely on
such writing as being genuine and what it purports to be without any necessity
of any investigation whatsoever. Noteholder similarly agrees that, prior to the
delivery to Borrower and Parent of a notice of the removal or termination of
Tamco as Collateral Agent as set forth below, Borrower and Parent shall be
entitled to rely on Tamco's or any subsequent Collateral Agent's authority to
act on behalf of Noteholder in all dealings with Tamco (or any such subsequent
Collateral Agent) with respect to the Loan and the Loan Documents; and Borrower
and Parent shall be protected in relying on actions, communications, notices and
terminations relating thereto or required or permitted thereunder by Collateral
Agent. In the event of the removal of Collateral Agent and the appointment of a
successor Collateral Agent by Noteholder, Borrower and Parent shall not be
required to recognize any such removal or appointment unless and until Borrower
and Parent shall have received a writing setting forth such removal and
appointment executed by Noteholder, and Borrower and Parent shall be entitled to
rely on such writing as being genuine and what it purports to be without any

                         EVENTS OF DEFAULT AND REMEDIES

           Section 7.1.  Events of Default.
                         ----------------- 

          (a)  Each of the following events constitutes an Event of Default
under this Agreement:
 
               (i)   Any event listed on Annex D attached hereto.

               (ii)  Any Material Adverse Change occurs in Borrower's individual
          (or Parent's Consolidated) financial condition, assets, business or
          operations and 

                                     - 31 -
<PAGE>
 
          such adverse change is not remedied within sixty (60) days thereafter.

               (iii) The occurrence of (A) a total of three (3) 100% Quarters
          within a five (5) consecutive Calendar Quarter period, or (B) a total

               (iv)  The occurrence of a Coverage Default which is not cured
          within thirty (30) days as provided in Section 5.2(a).
                                                 -------------- 

          (b) Upon the occurrence of an Event of Default described in 
Section D.10 (a), (b) or (c) of Annex D with respect to Borrower or the 
- ----------------------------

the Obligations shall thereupon be immediately due and payable, without demand,
presentment, notice of demand or of dishonor and nonpayment, protest, notice of
protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by Borrower and each Related Person who at any time
ratifies or approves this Agreement. During the continuance of any other Event
of Default, Noteholder at any time and from time to time may without notice to
Borrower or any other Related Person declare any or all of the Obligations
immediately due and payable, and all such Obligations shall thereupon be
immediately due and payable, without demand, presentment, notice of demand or of
dishonor and nonpayment, protest, notice of protest, notice of intention to
accelerate, declaration or notice of acceleration, or any other notice or
declaration of any kind, all of which are hereby expressly waived by Borrower

After any such acceleration (whether automatic or due to declaration by
Noteholder), any obligation of Noteholder to make any further loans of any kind
under any agreement with Borrower shall be permanently terminated.

          Section 7.2.  Remedies.  If any Default shall occur and be continuing,
                        --------                                                
Noteholder may protect and enforce its rights under the Loan Documents by any
appropriate proceedings, 

                                     - 32 -
<PAGE>
 
including proceedings for specific performance of any covenant or agreement
contained in any Loan Document, and Noteholder may enforce the payment of any
Obligations due or enforce any other legal or equitable right. All rights,
remedies and powers conferred upon Noteholder, Agent or Collateral Agent under
the Loan Documents shall be deemed cumulative and not exclusive of any other
rights, remedies or powers available under the Loan Documents or at law or in
equity.

          Section 7.3.  Indemnity.  Borrower and Parent jointly and severally
                        ---------                                            
agree to indemnify each TCW Entity, upon demand, from and against any and all
liabilities, obligations, claims, losses, damages, penalties, fines, actions,
judgments, suits, settlements, costs, expenses or disbursements (including 
reasonable fees of attorneys, accountants, experts and advisors) of any kind or
nature whatsoever (in this section collectively called "liabilities and costs")
which to any extent (in whole or in part) may be imposed on, incurred by, or
asserted against such TCW Entity growing out of, resulting from or in any other
way associated with any of the Collateral, the Loan Documents, or the
transactions and events (including the enforcement or defense thereof) at any
time associated therewith or contemplated therein (including any violation or
noncompliance with any Environmental Laws by any Related Person or any
liabilities or duties of any Related Person or of any TCW Entity with respect to
Hazardous Materials found in or released into the environment). In furtherance
thereof, Borrower and Parent also agree to indemnify each TCW Entity, upon
demand, from and against any all liabilities and costs arising from their
failure to approve the Crysen Acquisition.

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART,
UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR ARE IN ANY EXTENT CAUSED, IN
WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY TCW
ENTITY,

provided only that no TCW Entity shall be entitled under this section to receive
indemnification for that portion, if any, of any liabilities and costs which (a)
is proximately caused by its 

                                     - 33 -
<PAGE>
 
own individual gross negligence or willful misconduct, as determined in a final
judgment, or by its own individual actions with respect to Collateral in its
possession, or (b) is owed by it to Noteholder as a result of such TCW Entity's
breach of a duty owed by it to Noteholder, but only to the extent proximately
caused by such breach. As used in this section the term "TCW ENTITY" refers to
each of Noteholder, Agent, Collateral Agent, Trustco, Tamco, and each director,
officer, agent, trustee, manager, attorney, employee, representative and
Affiliate of any such Person.

          Section 7.4.  Substitution of Operator.  During the continuance of any
                        ------------------------                                
Event of Default, Collateral Agent shall (in addition to all of its other
remedies) have the right, exercisable in its sole and absolute discretion, to
demand in writing that Borrower resign as the operator (whether under an
applicable joint operating agreement, in the records of any applicable
regulatory authority, or otherwise) of all or any of the Properties constituting
Collateral.  Upon receiving such written demand (in this section called a
"RESIGNATION DEMAND") from Collateral Agent, Borrower shall immediately take
whatever actions are legally available to it in order to facilitate the
succession of a reputable third party, chosen by Collateral Agent in its sole
and absolute discretion, to the position as operator of any property or group of
properties included in the Properties constituting Collateral and covered by the
subject Resignation Demand.  Without limitation of the generality of the
foregoing:

          (a) In the event Borrower owns one hundred percent (100%) of the
working interest in a Property or group of properties covered by a Resignation
Demand, Borrower shall immediately turn over operation of such Property or group
of Properties to the successor operator chosen by Collateral Agent, and shall
further execute or cause to be executed and filed with the appropriate
regulatory authorities any such instruments as may be requested by Collateral
Agent in order to document or effect such succession.

          (b) In the event Borrower owns less than 100% of the working interest
in a Property or group of Properties covered by a Resignation Demand, Borrower
shall:

                                     - 34 -
<PAGE>
 
               (i)   notify any nonoperators of its resignation, such
     notification to be made in writing and otherwise made in accordance with
     the provisions of any applicable joint operating agreement or similar
     agreement;

               (ii)  take whatever action is legally available to it in order to
     expedite the effective time that a successor operator shall assume
     Borrower's duties as operator (by way of example and not by way of
     limitation, Borrower shall facilitate the election and succession of a new
     operator without waiting for any applicable grace period to expire under
     the operative joint operating agreement or similar agreement); and

               (iii) cast its vote under the applicable joint operating
     agreement or similar agreement successor operator chosen by Collateral
     Agent, and such vote shall be cast by Borrower for the successor chosen by
     Collateral Agent both on an interim basis (if called for under the
     applicable joint operating agreement or similar agreement) and on a
     permanent basis.

of conduct or otherwise) by Noteholder, Agent or Collateral Agent in exercising
any right, power or remedy which either may have under any of the Loan Documents
shall operate as a waiver thereof or of any other right, power or remedy, nor
shall any single or partial exercise by Noteholder, Agent or Collateral Agent of
any such right, power or remedy preclude any other or further exercise thereof
or of any other right, power or remedy.  No waiver of any provision of any Loan
Document and no consent to any departure therefrom shall ever be effective

                        -----------------------------------------             
various representations, warranties, covenants and agreements in the Loan
Documents shall survive the execution and delivery of this Agreement and the
other Loan Documents and the performance hereof and thereof, including the
making or granting of the Loan and the delivery of the Notes and the other Loan
Documents, and shall further survive until all of the Obligations are paid in

          SECTION 8.5.  GOVERNING LAW; SUBMISSION TO PROCESS. EXCEPT TO THE
                        ------------------------------------               
EXTENT THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A LOAN
DOCUMENT, THE LOAN DOCUMENTS SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH
AND GOVERNED BY THE LAWS OF THE STATE OF CALIFORNIA AND OF THE UNITED STATES OF
AMERICA (WITHOUT REGARD TO CALIFORNIA PRINCIPLES OF CONFLICTS OF LAW).  EACH OF
BORROWER AND PARENT HEREBY IRREVOCABLY SUBMITS ITSELF AND EACH OTHER RELATED
PERSON TO THE NON-EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS SITTING
IN THE STATE OF CALIFORNIA AND THE COUNTY OF LOS ANGELES AND AGREES AND CONSENTS
THAT SERVICE OF PROCESS MAY BE MADE UPON IT OR ANY OF ITS SUBSIDIARIES IN ANY

IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
OBJECTION THAT 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

          Section 8.6.  Limitation on Interest.  Noteholder, Agent, Collateral
                        ----------------------                                
Agent, the Related Persons and any other parties to the Loan Documents intend to
contract in strict compliance with applicable usury law from time to time in
effect. In furtherance thereof such Persons stipulate and agree that none of the
terms and provisions contained in the Loan Documents shall ever be construed to
create a contract to pay, for the use, forbearance or detention of money,
interest in excess of the maximum amount of interest permitted to be charged by
applicable law from time to time in effect.  Neither any Related Person nor any
present or future guarantors, endorsers, or other Persons hereafter becoming
liable for payment of any Obligation shall ever be liable for unearned interest
thereon or shall ever be required to pay interest thereon in excess of the
maximum amount that may be lawfully charged under applicable law from time to
time in effect, and the provisions of this section shall control over all other
provisions of the Loan Documents which may be in conflict or apparent conflict
herewith.  Noteholder, Agent and Collateral Agent expressly disavow any
intention to charge or collect excessive unearned interest or finance charges in
the event the maturity of any Obligation is accelerated.  If (a) the maturity of
any Obligation is accelerated for any reason, (b) any Obligation is prepaid and
as a result any amounts held to constitute interest are determined to be in
excess of the legal maximum, or (c)  Noteholder or any other holder of any or
all of the Obligations shall otherwise collect moneys which are determined to
constitute interest which would otherwise increase the interest on any or all of
the Obligations to an amount in excess of that permitted to be charged by
applicable law then in effect, then all such sums determined to constitute
interest in excess of such legal limit shall, without penalty, be promptly
applied to reduce the then outstanding principal of the related Obligations or,
at Noteholder's or such holder's option, promptly returned to Borrower or the
other payor thereof upon such determination.  In determining whether or not the
interest paid or payable, under any specific circumstance, exceeds the maximum
amount permitted under applicable law, Agent, Noteholder, Collateral Agent and
the Related Persons (and any other payors thereof) shall to the 

                                     - 40 -
<PAGE>
 
greatest extent permitted under applicable law, (i) characterize any 
non-principal payment as an expense, fee or premium rather than as interest, 
(ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the instruments evidencing the Obligations in accordance
with the amounts outstanding from time to time thereunder and the maximum legal
rate of interest from time to time in effect under applicable law in order to
lawfully charge the maximum amount of interest permitted under applicable law.

          Section 8.7.  Termination; Limited Survival.  In its sole and absolute
                        -----------------------------                           
discretion Borrower may at any time that no Obligations are owing under the Loan
Documents elect in a notice delivered to Noteholder to terminate this Agreement
and the other Loan Documents. Upon receipt by Noteholder of such a notice, if no
such Obligations are then owing then this Agreement and all other Loan Documents
shall thereupon be terminated, the Liens thereunder released, and the parties
thereto released from all prospective obligations thereunder. Notwithstanding
the foregoing or anything herein to the contrary, any waivers or admissions made
by any Related Person in any Loan Documents, the obligations of Parent and
Borrower under Section 7.3, and any other obligations which any Person may have
               -----------                                                      
to indemnify or compensate Noteholder or any of Noteholder's Affiliates shall
survive any termination of this Agreement or any other Loan Document.  At the
request and expense of Borrower, Noteholder shall prepare and execute all
necessary instruments to reflect and effect such termination of the Loan
Documents.

          Section 8.8.  Severability.  If any term or provision of any Loan
                        ------------                                       
Document shall be determined to be illegal or unenforceable all other terms and
provisions of the Loan Documents shall nevertheless remain effective and shall
be enforced to the fullest extent permitted by applicable law.

          Section 8.9.  Counterparts.  This Agreement may be separately executed
                        ------------                                            
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to constitute one
and the same Agreement.

                                   SCHEDULE 5

                  Calculation of 12.5% Internal Rate of Return
                  --------------------------------------------


        Reference is made to the Credit Agreement to which this Schedule is
attached for the meaning of terms defined therein and used herein without
further definition.  As used herein, the following additional terms have the
following meanings:

        "LOAN DOCUMENT DISBURSEMENTS" means, with respect to the A Note,
$65,000,000 of the Advance and all other amounts advanced or expended by
Noteholder, Agent or Collateral Agent which Borrower is obligated to repay or
reimburse under the Credit Agreement or any Loan Document, and, with respect to
the B Note, $10,000,000 of the Advance.

        "LOAN DOCUMENT PAYMENTS" means all payments received by Noteholder,
Agent or Collateral Agent pursuant to any Loan Documents, including all interest
and principal on the Note (excluding any interest in excess of 9.75% per annum
paid on any past due amount), the financing fee payable under Section 2.4 of the
Credit Agreement and all reimbursements of other Loan Document Disbursements.

        "12.5% IRR" means a twelve and one-half (12.5%) percent nominal, cash-
on-cash internal rate of return on all Loan Document Disbursements calculated
over the period from the date of the initial Advance to the date in question.
The method of calculating such rate of return is set forth in the example on
page 5-3 of this Schedule (the "Example Calculation"), and the present value
discount factors to be used for calculating such internal rate of return are set
forth on page 5-4 of this Schedule.

        The periods referred to in the Example Calculation are calendar quarters
(January through March, April through June, July through September, and October
through December), with the exception of Period 0, which is from the date of the
Advance under the Note to and including September 30, 1997, and Period 1, which
is the period beginning on September 30, 1997 and ending on December 31, 1997.

        All Loan Document Disbursements and all Loan Document Payments will be
treated as shown in the Example Calculation.

                                     - 1 -
<PAGE>
 
The Advance will be discounted by a discount factor of 1.0.  The financing fee
will be discounted by a discount factor of 1.0 provided the fee is received on
the date of the Advance.  Each subsequent Loan Document Disbursement will be
discounted by the discount factor corresponding to the period in which it is
advanced or disbursed (e.g., a Loan Document Disbursement made in October 1997
would be discounted by a factor of 0.969365).  All Loan Document Payments will
be discounted by the discount factor corresponding to the period in which they
are received (e.g., Loan Document Payments received in March, 1998 will be
discounted by a factor of 0.939991).

        If Noteholder elects to have a 12.5% IRR calculated on all but
$10,000,000 of the Loan Document Disbursements (as to which $10,000,000 the
12.5% IRR Calculation shall be made at the time and in the manner set forth in
the Warrant Documents), the last $10,000,000 advanced on the Loan will be
excluded from the "Advance to Borrower" in calculating the Additional Interest
and "NPV of Cash Proceeds".

        When the "NPV of Total Loan Amount" less the "NPV of Cumulative Cash
Proceeds" is less than or equal to zero, after Additional Interest has been paid
Noteholder will have been given a 12.5% IRR.  In the Example Calculation, this
occurs in the quarter ending June 2000.

required under the Bank Documents (herein called the "Scheduled Bank Payments").
All parties hereto acknowledge and agree that on or before the Payment Date
following each Calculation Quarter, all ANCF with respect to such Calculation
Quarter (and any proceeds from Approved Sales or Financings, proceeds from sales
of equity of Parent and any other sources of funds received by Borrower, Parent
or any other Related Person, in each case to the extent used to pay, redeem,
purchase or discharge Bank Indebtedness or TCW Indebtedness) shall be applied in
the following order (the "ANCF Hierarchy"):

          (i)  first, to any Scheduled Bank Payments, payments in respect of
     Permitted Interest Rate Hedges and any interest or fees on, or other non-
     principal items of, Allowed Bank Indebtedness, to the extent such Scheduled
     Bank Payments, payments in respect of Permitted Interest Rate Hedges,
     interest, fees or other non-principal items are due on or before such
     Payment Date,

                                       9
<PAGE>
 
          (ii)  second, to any Allowed Bank Indebtedness which has been
     accelerated and become due in accordance with the terms of both this
     Agreement and the Bank Documents,

          (iii)  third, to any interest or fees on, or other non-principal items
     of, TCW Indebtedness, to the extent such interest, fees or other items are
     due (whether due to acceleration thereof or otherwise) on or before such
     Payment Date,

          (iv)  fourth, to any payments of principal (other than those described
     in subsections (i) and (ii) above) which are due on the Allowed Bank
     Indebtedness on or before such Payment Date,

          (v)  fifth (but only on or after the Initial TCW Amortization Date),
     to any payments of principal which are due on the TCW Indebtedness (whether
     due to acceleration thereof or otherwise) on or before such Payment Date,

          (vi)  sixth, except during any 100% Dedication Quarter, up to ten
     percent (10%) of the ANCF for such Calculation Quarter may be retained by
     Borrower and used in Borrower's business,

          (vii)  seventh, (x) if made during the Revolver Period to prepay
     Allowed Bank Indebtedness, subject to the Borrower's ability to obtain
     subsequent advance pursuant to the terms of the Bank Documents or the TCW
     Documents or (y) if made after the Revolver Period to prepay any Scheduled
     Bank Payments (other than those described in subsection (i), (ii) or (iv)
     above), in inverse order of maturity,

          (viii)  eighth, after all Scheduled Bank Payments and other Allowed
     Bank Indebtedness have been paid (or if the Banks elect not to accept any
     prepayments under the preceding subsection (vii)), to prepay or repay any
     TCW Indebtedness,

          (ix)  ninth, after all TCW Indebtedness has been paid (or if the
     Noteholders elect, in their sole and absolute discretion not to accept any
     prepayments under the preceding section (viii)), to repay any Excess Bank
     Indebtedness, to the extent Excess Bank Indebtedness is due (whether due to
     acceleration or otherwise), and

          (x)  tenth, the remainder may be retained by Borrower and used in
     Borrower's business.

This Section 3(a) is intended only to create an obligation of Borrower to pay
and apply ANCF and other amounts described therein in the order and the
respective amounts set forth therein, and 

                                       10
<PAGE>
 
to create an obligation on the Banks and the Noteholders to turnover funds
improperly received or collected as more particularly set forth in Section 9. No
failure of Borrower to make payment or application of ANCF or any other amount
to the Indebtedness in the manner provided in Section 3(a), and no failure of
the Banks or Agent Lender to enforce such payment or application nor any other
act or omission by Borrower or Banks or Agent Lender shall cause any Allowed
Bank Indebtedness to be deemed to have been paid nor to otherwise no longer be
entitled to the priority of payment set forth in this Section 3(a) nor affect
any other right or privilege of the Banks or the Agent Lender. No failure of
Borrower to make payment or application of ANCF or any other amount to the
Indebtedness in the manner provided in Section 3(a), and no failure of the
Noteholders or the Agent Noteholder to enforce such payment or application nor
any other act or omission by Borrower or the Noteholders or the Agent Noteholder
shall cause any TCW Indebtedness to be deemed paid nor to otherwise no longer be
entitled to the priority of payment set forth in this Section 3(a) nor affect
any other right or privilege of the Noteholders or the Agent Noteholder.

          (b)  As further provided in Sections 5 and 6, (i) neither the amount
nor the date for payment of any Scheduled Bank Payment may be modified and no
provision of the Bank Documents may be amended or modified to increase the rate
or the manner of determining interest, fees, expenses or other non-principal
items due on the Allowed Bank Indebtedness, without the prior consent of the
Agent Noteholder, and (ii) the scheduled dates for payment of the principal of
the TCW Indebtedness shall not be modified to occur prior to the Initial TCW
Amortization Date and no provision of the TCW Documents may be amended or
modified to increase the rate or the manner of determining interest, fees,
expenses or other non-principal items due on the TCW Indebtedness, without the
consent of the Agent Lender, if either the Revolver Period has not ended or
there is any outstanding Allowed Bank Indebtedness.  No Excess Bank
Indebtedness shall be lent to or incurred by Borrower, Parent or any Related
Person without the consent of the Agent Noteholder until all TCW Indebtedness
has been paid in full, and no loans in excess of $75,000,000 shall be made to
Borrower, Parent or any Related Person or borrowed by Borrower under the TCW
Documents without the consent of the Agent Lender until all Allowed Bank
Indebtedness has been paid in full.

          (c) Interest on each Eurodollar Loan, as defined and provided for
under the Bank Agreement, is payable on the last day of the Interest Period for
such Eurodollar Loan and, in the case of any Interest Period in excess of 90
days, on the 90th day of such Interest Period.  Payments on Permitted Interest
Rate Hedges may come due on a day other than a Quarterly Payment Date.
Notwithstanding Section 3(a), such Interest on each Eurodollar Loan shall be
paid when due under the Bank Agreement and payments on Permitted Interest Rate
Hedges shall be paid when due under the Bank Interest Rate Hedge Agreement and
each shall, for purposes of the ANCF Hierarchy, be accounted for out of ANCF as
if paid on the next succeeding Quarterly Payment Date.

          Section 4.  Rights to Cure Defaults.
                      ----------------------- 

          (a)  Within two Business days after determining that any Bank Default
has occurred, the Borrower will give notice of such Bank Default to the Agent
Noteholder.  Agent Lender may, but is not obligated to, give notice of any Bank
Default to the Agent Noteholder. Although no Noteholder has any obligation to
cure any Bank Default, Borrower hereby authorizes each Noteholder to make any
such cure, if any Noteholder so elects, and the Banks hereby agree that they
will allow such Noteholder to make any such cure on behalf of Borrower, provided
such cure is in compliance with the Bank Agreement and does not otherwise cause
a Bank Default.  The Banks further agree that without the consent of the Agent
Noteholder no Bank shall commence or continue any Enforcement Action with
respect to any Bank Default until the earlier to occur of (i) the ninetieth
(90th) day after the date upon which the Agent Lender receives notice of such
Bank Default from the Borrower or the Agent Noteholder (and then only if such
Bank Default remains uncured and otherwise continues to exist) and (ii) any
acceleration of the TCW Indebtedness or any enforcement by any Noteholder of any
Lien upon assets of Borrower in compliance with the terms hereof.

          (b)  Within two Business days after determining that any TCW Default
has occurred, the Borrower will give notice of such TCW Default to the Agent
Lender.  Agent Noteholder may, but is not obligated to, give notice of any TCW
Default to the Agent Lender. Although no Bank has any obligation to cure any TCW
Default, Borrower hereby authorizes each Bank to make any such cure, if any Bank
so elects, and the Noteholders hereby agree that they will allow such Bank to
make any such cure on behalf of Borrower, provided such cure is in compliance
with the TCW Agreement and does not otherwise cause a TCW Default.  The
Noteholders further agree that without the consent of the Agent Lender, no
Noteholder shall commence or continue any TCW Enforcement Action with respect to
any TCW Default until the earlier to occur of (i) the ninetieth (90th) day
after the date upon which the Agent Noteholder receives notice of such TCW
Default from the Borrower or the Agent Lender (and then only if such TCW Default
remains uncured and otherwise continues to exist) and (ii) any acceleration of
the Bank Indebtedness or any enforcement by any Bank of any Lien upon assets of
Borrower in compliance with the terms hereof.

          Section 5.  Amendments to Bank Documents.  No provision of the Bank
                      ----------------------------                           
Documents shall, without the prior written consent of the Agent Noteholder, be
amended, supplemented, modified or waived if the effect of such amendment,
supplement, modification or wavier would be to (a) increase the rate of interest
or the manner of determining prepayment charges, fees, expenses or other amounts
payable with respect to (or constituting items of) the Allowed Bank Indebtedness
(provided that the foregoing shall not prevent the interest rate applicable to
any past due Allowed Bank Indebtedness from increasing by up to two percent per
annum as presently provided in the Bank Agreement), (b) change the date on which
any Scheduled Bank Payment becomes due or change the amount thereof, (c) change
the scheduled payment date of any other Allowed Bank Indebtedness, (d) add new
covenants or events of default, (e) extend the Commitment Period or allow a loan
under the Bank Documents after the 

                                       12
<PAGE>
 
March 31, 1999, or (f) otherwise change the terms of the Bank Documents in any
way which is more onerous to Borrower, Parent or any Related Person or causes,
or increases the likelihood of, the occurrence of a Bank Default The parties
recognize that the Bank Agreement is a revolving credit agreement until March
31, 1999, with floating interest rate options, and neither (i) the borrowing of
loans under such revolving credit feature (provided the aggregate outstanding
amounts thereof do not exceed the limits set forth above in the definition of
"Allowed Bank Indebtedness") nor (ii) any fluctuations in the underlying
eurodollar rate or prime rate on which are based the interest rate provisions of
the Bank Agreement, nor (iii) the occurrence of any event triggering Eurodollar
Rate costs or a late payment rate, shall be deemed to be a violation of this
Section 5.

          Nothing to the contrary contained in this Agreement shall (i)
restrict, prohibit or regulate the determinations which may be made from time to
time by the Banks or the Agent Lender under the Bank Agreement, including
specifically, but without limitation, the right of the Banks and/or Agent Lender
to determine the Borrowing Base from time to time in accordance with the
provisions of the Bank Agreement.  Any amount required to be repaid under the
Bank Agreement as a result of a Borrowing Base determination shall be paid
pursuant to clause (iv) of Section 3(a) of this Agreement.  Such required
payment shall not be considered a modification within the meaning of Section
3(b).  Borrower acknowledges and agrees that the Scheduled Bank Payments are
based upon the Borrowing Base currently in existence under the Bank Agreement
and the Banks will not increase the Borrowing Base under the Bank Agreement (i)
without an amendment to such Scheduled Bank Payments as determined by the Banks
in connection with such Borrowing Base increase and (ii) the consent of the
Agent Noteholder to such amendment to such Scheduled Bank Payments.

          Section 6.  Amendments to TCW Documents.  No provision of the TCW
                      ---------------------------                          
Documents shall, without the prior written consent of the Agent Lender, be
amended, supplemented, modified or waived if the effect of such amendment,
supplement, modification or wavier would be to (a) increase the rate of
interest, prepayment charges, fees, expenses or other amounts payable with
respect to (or constituting items of) the TCW Indebtedness (provided that the
foregoing shall not prevent the interest rate applicable to any past due TCW
Indebtedness from increasing to twelve percent per annum as presently provided
in the TCW Agreement), (b) provide for scheduled principal payments on the TCW
Indebtedness prior to the Initial TCW Amortization Date, (c) change the
scheduled payment date of any non-principal items of TCW Indebtedness, (d) add
new covenants or events of default, or (e) otherwise change the terms of the TCW
Documents in any way which causes, or increases the likelihood of, the
occurrence of a TCW Default.  The parties further recognize that, pursuant to
the TCW Agreement, Parent and Warrantholder entered into that certain Warrant
Agreement and Parent issued to Warrantholder certain Warrants as described in
the Warrant Agreement and that any exercise by Warrantholder of such Warrants or
any rights under the TCW Warrant Documents or any enforcement thereof shall not
be deemed to be a violation of this Section 6.

properties or assets of Borrower in any Insolvency Proceeding, or upon any
payment on behalf of Borrower in any Insolvency Proceeding:

          (a) The Banks shall be entitled to receive payment in full in cash of
the Allowed Bank Indebtedness, or provision must be made for immediate payment
in full in cash of the Allowed Bank Indebtedness, before the Noteholders are
entitled to receive any direct or indirect payment or distribution of properties
or assets of Borrower of any kind or character (whether in cash, property or
securities and by set-off or otherwise), other than Permitted Junior Securities,
on account of the TCW Indebtedness.

          (b) Any direct or indirect payment or distribution of properties or
assets of Borrower of any kind or character, other than a payment or
distribution in the form of Permitted Junior Securities, to which the
Noteholders would be entitled but for the provisions of this Agreement shall be
paid by Borrower or by any liquidating trustee or agent or other Person making
such payment or distribution, whether a trustee in bankruptcy, a receiver or
liquidating trustee or otherwise, directly to the Banks or their representative
or representatives, ratably according to the aggregate unpaid amounts of Allowed
Bank Indebtedness held or represented by each, to the extent necessary to make
payment in full of all Allowed Bank Indebtedness after giving effect to any
concurrent payment or distribution to the Banks.

          (c) If, notwithstanding the foregoing provisions of this Section 7,
any Noteholder shall receive any payment or distribution of properties or assets
of Borrower of any kind or character, other than a payment or distribution in
the form of Permitted Junior Securities, on account of the TCW Indebtedness
before all Allowed Bank Indebtedness is paid or provided for in full, then such
payment or distribution shall be received and held in trust for and shall be
paid over or delivered forthwith to the Banks remaining unpaid or their
representatives, to the extent necessary to pay all Allowed Bank Indebtedness in
full, after giving effect to any concurrent payment or distribution to or for
the Banks.

          (d) Except as provided in subsections (a), (b) and (c) of this Section
7, the Banks and the Noteholders will be entitled to freely exercise all rights
and remedies available to them in any Insolvency Proceeding.  Furthermore,
nothing in this Section 7 or any other provision of this Agreement shall be
deemed or construed to constitute a waiver by Agent Noteholder or any Noteholder
of any right to vote for or against or to propose any plan of reorganization in
any Insolvency Proceeding, all of which are expressly reserved and retained by
Agent Noteholder and the Noteholders.

          Section 8.  Notice of Acceleration; Right to Purchase Indebtedness.
                      ------------------------------------------------------ 

          (a)  Within one business day after any acceleration of the maturity of
any Allowed Bank Indebtedness, the Agent Lender will give notice thereof to the
Agent Noteholder.  Within 

                                       14
<PAGE>
 
one business day after any acceleration of the maturity of any TCW Indebtedness,
the Agent Noteholder will give notice thereof to the Agent Lender.

          (b)  The Banks will at any time during the continuance of any Bank
Default or Insolvency Proceeding, upon request by the Agent Noteholder, assign
all of the Allowed Bank Indebtedness and all appurtenant Liens, rights,
documents and instruments to the Noteholders for a price equal to 100% of the
Allowed Bank Indebtedness.

          (c)  Before any Noteholder sells any TCW Indebtedness, it shall first
give written offer to the Agent Lender to sell such TCW Indebtedness, specifying
the amount of TCW Indebtedness to be sold and all material terms of such sale.
The Banks shall have the right to purchase such TCW Indebtedness on such offered
terms for a period of 45 days ("Offer Period") after receipt by the Agent Lender
of such notice.  If the Banks do not purchase such TCW Indebtedness during such
Offer Period, the Noteholder may sell the TCW Indebtedness to any third party on
the same terms which were offered to the Banks for a period of 180 days
following the end of such Offer Period.  Such Noteholder must again provide the
Banks an offer to sell TCW Indebtedness as a condition to (i) any sale of TCW
Indebtedness after such 180 day period or (ii) any sale of TCW Indebtedness on
terms more favorable to the proposed purchaser than the terms offered the Banks;
provided that such offer on more favorable terms to a proposed purchaser within
such 180 day period shall be limited to an Offer Period of 15 days after receipt
by Agent Lender of notice of such offer.  The provisions of this Section 8(c)
does not apply to any sale by a Noteholder to an Affiliate or to any transfer by
a Noteholder to any party having a beneficial interest in such Noteholder or in
any Note or to any custodian, sub-custodian, investment manager or designee of
such beneficial owner.

          Section 9.  Turnover of Payments Wrongly Received.  If Borrower shall
                      -------------------------------------                    
make any payment to a Noteholder which is prohibited hereby or any Noteholder
shall collect any payment as a result of an Enforcement Action which is
prohibited hereby, then such payment shall be paid over and delivered forthwith
by such Noteholder to the Agent Lender.  If Borrower shall make any payment to a
Bank which is prohibited hereby or any Bank shall collect any payment as a
result of an Enforcement Action which is prohibited hereby, then such payment
shall be paid over and delivered by such Bank to the Agent Noteholder.

          Section 10. Payments and Enforcement Actions Otherwise Permitted.
                      ----------------------------------------------------  
Except as expressly provided herein, nothing shall prevent Borrower from making,
or any Noteholder or Bank from receiving, any payments on the TCW Indebtedness
or Allowed Bank Indebtedness, as applicable, or limit the rights of the Banks or
the Noteholders to take Enforcement Actions.

          Section 11.  Subrogation to Rights of Banks.  After the payment in
                       ------------------------------                       
full of all Allowed Bank Indebtedness, the Noteholders shall be subrogated to
the rights of the Banks to receive payments and distributions of cash, property
and securities applicable to Allowed Bank Indebtedness and the Liens securing
the Allowed Bank Indebtedness until all amounts owing on the TCW Indebtedness
shall be paid in full.  For purposes of such subrogation, no payments or

                                       15

Borrower or by or on behalf of the Noteholders by virtue of this Agreement which
otherwise would have been made to the Noteholders shall, as between Borrower,
its creditors other than the Banks, and the Noteholders, be deemed to be a
payment or distribution by Borrower to or on account of the Allowed Bank
Indebtedness.

          Section 12.  Provisions Solely to Define Relative Rights.  The
                       -------------------------------------------      
provisions of this Agreement are, and are intended solely, for the purpose of
defining the relative rights of the Noteholders on the one hand and of the Banks
on the other hand.  Nothing contained in this Agreement is intended to or shall
(a) impair, as between Borrower and the Noteholders, the obligation of Borrower,
which is absolute and unconditional, to pay all TCW Indebtedness as and when the
same shall become due and payable in accordance with its terms; (b) affect the
relative rights against Borrower of the Noteholders and any creditors of
Borrower other than the Banks; or (c) prevent the Noteholders from exercising
all remedies otherwise permitted by applicable law upon default under the TCW
Agreement, subject to the rights of the Banks, if applicable, under this

other than the Noteholders; or (c) prevent the Banks from exercising all
remedies otherwise permitted by applicable law upon default under the Bank
Agreement, subject to the rights of the Noteholders, if applicable, under this
Agreement. Without the consent of the Borrower, the provisions of this Agreement
defining the relative rights of the Noteholders and the Banks may be modified by
the Noteholders and the Banks without modifying the rights of the Borrower,
provided that Agent Noteholder and Agent Lender shall give notice thereof to the
Borrower.

          Section 13.  Possession of Stock.  ING acknowledges that it holds the
                       -------------------                                     
stock of Borrower pursuant to the Pledge Agreements by Parent, for ING,  as
Agent for the Banks,  and for the Collateral Agent as defined under the TCW
Agreement, as agent for the Noteholders, to perfect the security interest
granted in such Pledge Agreements by Parent .  ING shall have no obligation or
duty to such Collateral Agent or Noteholders as a result thereof; provided that
upon payment in full of the Allowed Bank Indebtedness and the end of the
Revolving Period, ING shall not surrender the stock to the Parent but shall
deliver the same to the Collateral Agent.

          Section 14.  No Waiver.  No right of any Bank or Noteholder to enforce
                       ---------                                                
its rights as herein provided shall at any time or in any way be prejudiced or
impaired by any act or failure to act on the part of any other party hereto or
by any non-compliance by any other party with the terms of this Agreement,
regardless of any knowledge thereof which any such Bank or Noteholder may have
or otherwise be charged with (provided that in all events the Noteholders may
conclusively rely on the authority of the Agent Lender to act for the Banks and
that the Banks may conclusively rely on the authority of the Agent Noteholder to
act for the Noteholders). The rights and duties of the parties hereto shall
continue in effect and apply to the

Agreement shall be effective unless it is in writing and signed by Borrower, the
Agent Noteholder and the Agent Lender.  No waiver of any provision of this
Agreement, and no consent to any departure by Borrower, any Noteholder or any
Bank therefrom, shall be effective unless it is in writing and signed by both
the Agent Noteholder and the Agent Lender, and then such waiver or consent shall
be effective only in the specific instance and for the specific purpose for
which given.

          Section 16.  Governing Law.  This Agreement shall be deemed a contract
                       -------------

construed and enforced in accordance with and governed by the laws of such state
and the laws of the United States of America, without regard to principles of
conflicts of law.

          Section 17.  Invalidity of Particular Provisions.  If any term or
                       -----------------------------------                 
provision of this Agreement shall be determined to be illegal or unenforceable,
all other terms and provisions hereof shall nevertheless remain effective and
shall be enforced to the fullest extent permitted by applicable law.

Warrants or Warrant Stock, and

            (a)  in the case of loss, theft or destruction, on receipt of
          indemnity reasonably satisfactory to the Company (provided that, if
          the owner of the same is TCW or a commercial bank, its own agreement
          of indemnity shall be deemed to be satisfactory), or

      SECTION 5.  Registration Rights.
                  ------------------- 

          1.051.  Demand Registration.  At any time after the Warrants become
                  -------------------
exercisable and so long as the Company continues to have a class of securities
registered in accordance with Section 12 or Section 15A of the Exchange Act, the
holders of Restricted Securities may request the Company to register for sale
under the Securities Act and any applicable state securities or "blue sky" laws
all or any portion of the Restricted Stock that is then outstanding.  From and
after December 31, 2007, the holders of Restricted Stock shall have no further
rights to require the Company to register Restricted Stock pursuant to this
Section 5.01.  The Company shall be obligated to effect registration pursuant to
- ------------                                                                    
this Section 5.01 no more than one time, notwithstanding the fact that
     ------------                                                     
Restricted Stock may be held by more than one person.  Whenever the Company
shall have received a request to effect registration pursuant to this Section
                                                                      -------
5.01, the Company shall promptly give written notice to all other holders of
- ----                                                                        
outstanding Restricted Securities of such proposed registration.  Any such
holder of Restricted Securities may, within 30 days after receipt of such
notice, request that all of such holders' Restricted Stock, or any portion
thereof designated by such holder, be included in the offering.  In connection
therewith, the Company shall file a registration statement covering the
Restricted Stock sought to be registered by such holder with the Commission
within 60 days of such request by such holder, unless such request is withdrawn.
The managing underwriter in any such offering will be designated by the Seller
and shall be reasonably satisfactory to the Company.  Except as permitted in the
next succeeding paragraph, the Company agrees not to effect any public or
private sale or distribution of its equity securities during the 10-day period
prior to, and during the 30-day period beginning on, the effective date of the
registration statement relating to such offering.

          The Company, and any other shareholder of the Company entitled to
participate in such registration, may participate in such registration (i)
subject to the limitations set forth in the last paragraph of this Section 5.01
                                                                   ------------
and (ii) only if the Company or such other shareholder agrees (x) to sell any
shares being registered on their behalf on the same basis as provided in any
underwriting agreement to which the Seller or Sellers are a party, (y) to timely
complete and execute all questionnaires,

                                      -13-
<PAGE>
 
powers of attorney, indemnities, hold-back agreements and other documents
reasonably required under the terms of such underwriting agreement or by the
Commission or any state securities regulatory body, and (z) to withdraw any
shares from such registration which they may desire to withdraw only on terms
and at a time agreed to by the Sellers which agreement will not be unreasonably
withheld. If the Company participates in such registration and registers a
number of shares of Common Stock equal to or greater than the number being
registered by the Sellers, then the Company may specify a co-managing
underwriter for the offering which is reasonably acceptable to the Sellers and
the managing underwriter selected by the Sellers.

          If the managing underwriter for the offering advises that the
registration of the number of shares of Restricted Stock sought to be registered
by the Sellers, together with the number of shares of Common Stock sought to be
registered by the Company and any other shareholder of the Company entitled to
participate in such registration, if any, in its opinion will have a material
adverse impact on the offering (including without limitation causing the
proceeds or the price per share the Sellers will derive from such registration
to be reduced or causing the number of securities to be registered to be too
large a number to be reasonably sold), the number of securities sought to be
registered shall be reduced as follows:

               (a)  first, the number of shares of Common Stock sought to be
     registered by the Company or any holders of Common Stock, other than
     Restricted Stock, shall be reduced pro rata, to the extent necessary to
     reduce the total number of shares of Common Stock sought to be registered
     to the number recommended by the managing underwriter (the "Recommended
                                                                 -----------
     Number"); and
     ------       

               (b) second, if the reduction provided for in clause (a) above
     does not reduce the number of shares of Common Stock sought to be
     registered to the Recommended Number, then the remaining number of shares
     of Restricted Stock sought to be registered shall be reduced pro rata to
     the extent necessary to reduce the number of securities to be registered to
     the Recommended Number.

          1.052.  Piggyback Registration.  If the Company at any time proposes
                  ----------------------  
to register any of its equity securities under the Securities Act on Form S-1,
S-2, S-3 or SB-2, or the equivalent, whether of its own accord or at the request
of any holder or holders of such securities, it will each such time (so long as
any holder of Restricted Securities has registration rights under this Section
                                                                       -------
5.02) give written notice to all holders of outstanding Restricted Securities of
- ----                                                                            
its intention so to do not less than 30 days prior to the filing of such
registration statement, stating in such notice the number and type of equity
securities proposed to be registered and the name of the managing underwriter.

          Upon the written request of a holder or holders of any Restricted
Securities given within 20 days after receipt of any such notice (stating the
intended method of disposition of such securities by the prospective Seller or
Sellers), the Company will use its best efforts to cause all Restricted Stock,
the holders of which shall have so requested registration thereof, to be
registered under the Securities Act, all to the extent requisite to permit the
sale or other disposition (in accordance with the intended methods thereof as
aforesaid) by the prospective Seller or Sellers of the Restricted Stock so
registered; provided, however, the Company may elect not to file a registration
            --------  -------                                                  
statement pursuant to this Section 5.02 or may withdraw any registration
                           ------------                                 
statement filed pursuant to this Section 5.02 at any time prior to the effective
                                 ------------                                   
date thereof.  In the case of an underwritten public equity offering by the
Company, (i) each holder of Restricted Securities shall, if requested by the
managing underwriter, agree not to sell publicly any equity securities of the
Company held by such holder of Restricted Securities (other than the Restricted
Stock so registered) during the 15-day period prior to, and during the 90-day
period beginning on, the effective date of the registration statement relating
to such offering (and the Company may issue stop transfer instructions with
respect to the Restricted Stock to enforce the foregoing covenant), and (ii)
each Seller agrees (x) to sell any shares being registered on his behalf on the
same basis as provided in any underwriting agreement to which the Company is a
party, (y) to timely complete and execute all questionnaires, powers of
attorney, indemnities, hold-back 

                                      -15-
<PAGE>
 
agreements, and other documents reasonably required under the terms of such
underwriting agreement or by the Commission or any state securities regulatory
body, and (z) to withdraw any shares from such registration which they may
desire to withdraw only on terms and at a time agreed to by the Company, which
agreement will not be unreasonably withheld.

          If the managing underwriter for the offering advises that the
inclusion in such registration of the Restricted Stock sought to be registered
by the Seller or Sellers, together with the shares sought to be registered by
the Company and any other shareholder of the Company participating in such
registration, in its opinion will have a material adverse impact on the offering
(including without limitation causing the proceeds or the price per share which
the Company or the holders of securities will derive from such registration to
be materially reduced or causing the number of securities to be registered to be
too large a number to be reasonably sold), the number of securities sought to be
registered shall be reduced as set forth below:

            (a)  first, the number of shares of Restricted Stock sought to be
     registered by the Sellers shall be reduced pro rata along with other
     sellers selling pursuant to similar piggyback registration rights (subject
     only to the terms of agreements in effect dated prior to the date hereof,
     if any, providing piggyback registration rights to holders of the Company's
     capital stock), to the extent necessary to reduce the total number of
     shares of Common Stock sought to be registered to the Recommended Number;
     and

            (b)  second, if the reduction provided for in clause (a) above does
     not reduce the number of shares of Common Stock sought to be registered to
     the Recommended Number, then the number of shares of Common Stock sought to
     be registered by the Company or other persons exercising demand
     registration rights, as the case may be, shall be reduced, in the manner
     that the Company and such other persons may agree, to the extent necessary
     to reduce the number of shares of Common Stock sought to be registered to
     the Recommended Number.

          Without the prior written consent of the holders of at least a
majority of the Restricted Stock, the Company will not grant to any person at
any time on or after the date hereof the right to request the Company to
register any securities of the Company under the Securities Act unless such
right provides that such securities shall not be registered and sold at the same
time as any Restricted Stock is being sold in a registered offering pursuant to
Sections 5.02 or 5.01 if the managing underwriter for the respective Sellers
- ---------------------                                                       
believes that sale of such securities would materially and adversely affect the
amount of, or price at which, the respective Restricted Stock being registered
under Sections 5.01 or 5.02 can be sold.

                 -----------------------                               
required by the provisions of this Section 5 to use its best efforts to effect 
                                   --------- 
the registration of any of the Restricted Stock under the Securities Act, the
Company will (except as otherwise provided in this Agreement), as expeditiously
as possible,

               (a)  cooperate with any underwriters for, and the Sellers of,
     such Restricted Stock, and will enter into a usual and customary
     underwriting agreement (containing indemnification provisions and
     procedures no less favorable to the Sellers and the underwriters, if any,
     than those set forth in Section 5.07) with respect thereto and take all
                             ------------                                   
     such other reasonable actions as are necessary to permit the disposition of
     such Restricted Stock in the manner contemplated by the related
     registration statement, and the Company will provide to any Seller of
     Restricted Stock, any underwriter participating in any distribution
     thereof, pursuant to a registration statement, and any attorney, accountant
     or other agent retained by any Seller or underwriter, reasonable access
     solely for the purpose of permitting appropriate "due diligence" for the
     avoidance of liability under applicable securities laws to appropriate
     Company officers and employees to answer questions and to supply
     information reasonably requested by any such Seller, underwriter, attorney,
     accountant or agent in connection with such registration statement;

                                      -17-
<PAGE>
 
               (b)  use its best efforts to furnish or cause to be furnished to
     each Seller of Restricted Stock covered by such registration statement,
     addressed to such Sellers and to the underwriters, a copy of the opinion of
     counsel for the Company, and a copy of the "comfort" letter signed by the
     independent public accountants who have certified the Company's financial
     statements included in the registration statement, delivered on the closing
     date to the underwriters of such Restricted Stock;

               (c)  prepare and file with the Commission a registration
     statement with respect to such securities and use its best efforts to cause
     such registration statement to become and remain effective; and prepare and
     file with the Commission such amendments and supplements to such
     registration statement and the prospectus used in connection therewith as
     may be necessary to keep such registration statement effective (subject to
     the terms of this Section 5) and to comply with the provisions of the

     Securities Act with respect to the sale or other disposition of all
     securities covered by such registration statement whenever the Seller or
     Sellers of such securities shall desire to sell or otherwise dispose of the
     same; provided that no such registration statement will be filed by the
     Company until counsel for the Sellers of securities included therein shall
     have had a reasonable opportunity (of no more than 7 days) to review the
     same and to exercise their rights under clause (a) above with respect
     thereto and no amendment to any such registration statement naming such
     Sellers as selling shareholders shall be filed with the Commission until
     such Sellers shall have had at least one day to review such registration
     statement as originally filed and theretofore amended (to the extent
     reasonably practicable) and to exercise their rights under clause (a)
     above;

               (d)  furnish to each Seller and the underwriters (i) such numbers
     of copies of a summary prospectus or other prospectus, including a
     preliminary prospectus, in conformity with the requirements of the
     Securities Act, and such other documents, as such Seller or underwriters
     may reasonably request in order to facilitate the public sale or

                                      -18-

     other disposition of the securities owned by such Seller and (ii) at least
     one signed copy of the registration statement and any post-effective
     amendment thereto, including all financial statements, schedules and
     exhibits (including any exhibits incorporated by reference);

               (e)  use its best efforts to register or qualify the securities
     covered by such registration statement under such other securities or blue
     sky laws of such jurisdictions as each Seller or the managing underwriter
     shall reasonably request, and do any and all other acts and things which
     may be necessary to enable such Seller to consummate the public sale or
     other disposition in such jurisdictions of the securities owned by such
     Seller, except that the Company shall not for any such purpose be required
     to qualify to do business as a foreign corporation in any jurisdiction
     wherein it is not so qualified or to file therein any general consent to
     service or submit to the general taxation of any jurisdiction;

               (f) in the event of the issuance of any stop order suspending the
     effectiveness of any registration statement or of any order suspending or
     preventing the use of any prospectus or suspending the qualification of any
     Restricted Stock for sale in any jurisdiction, use its best efforts
     promptly to obtain its withdrawal;

               (g)  otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission, and make available to its security
     holders, as soon as reasonably practicable, an earnings statement covering
     the period of at least twelve months, beginning with the first fiscal
     quarter beginning after the effective date of the registration statement,
     which earnings statement shall satisfy the provisions of Section 11(a) of
     the Securities Act; and

               (h)  list such securities on any securities exchange, national
     market system or automated quotation system on which any stock of the
     Company is then listed, if the listing of such securities is then permitted
     under the

     any other provision of this Section 5, the Company shall not be required to
                                 ---------
     maintain the effectiveness of any registration statement for a period in
     excess of the earlier of 120 days or the disposition of the Warrant Stock
     as described therein (plus any period during which the effectiveness of
                           ----
     such registration has been suspended).

          Notwithstanding anything to the contrary contained herein, the Company
shall not be required to cause a registration statement previously filed
pursuant to this Section 5 to become effective, and may suspend sales by any of
                 ---------                                                     
the Sellers under any registration that has previously become effective, at any
time when, in the good faith judgment of the board of directors, it reasonably
believes that the effectiveness of such registration statement or the offering
of securities pursuant thereto, would materially and adversely affect a pending
or proposed material acquisition, merger, recapitalization, reorganization or
similar transaction or negotiations, discussions or pending proposals with
respect thereto.

          From time to time after a transfer of Warrant Stock pursuant to a
registration statement, the Company will file all reports required to be filed
by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the Commission thereunder, and will take such further
action as any holder or holders of Restricted Stock may reasonably request, all
to the extent required to enable such holders to sell Restricted Stock pursuant
to such laws and regulations thereunder and subject to the terms hereof; and
promptly notify the Seller or Sellers and the managing underwriters (i) when any
prospectus or any prospectus supplement or post-effective amendment has been
filed, and, with respect to the registration statement or any post-effective
amendment, when the same has become effective, (ii) of any request by the
Commission for amendments or supplements to the registration statement or any
prospectus or for additional information, (iii) of the issuance by the
Commission of any stop order suspending the effectiveness of the registration
statement or the initiation of any proceedings for that purpose, (iv) of the
receipt by the Company of any notification with respect to the suspension of the
qualification 

                                      -20-

of the Restricted Securities for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose, and (v) of the happening of any
event which makes any statement made in the registration statement, any
prospectus or any document incorporated therein by reference untrue in any
material respect or which requires the making of any changes in the registration
statement in order to make the statements therein not misleading in any material
respect.

<PAGE>
 
Seller shall furnish to the Company such information regarding the securities
held by such Seller and the intended method of disposition thereof as the
Company shall reasonably request and as shall be required in connection with the
action to be taken by the Company.

          The holders of Warrants and Warrant Stock shall be entitled to an
aggregate of one effective registration pursuant to requests made under Section
                                                                        -------
5.01 and an unlimited number of registrations pursuant to requests made under
- ----

- ------------                                    ------------                
that any such registration request made by the requisite number of holders
specified in Section 5.01 which request shall be withdrawn (other than by reason
             ------------

adverse change in its financial position, business or business prospects) by the
holders of a majority in number of shares evidenced or covered by the Restricted
Stock sought to be so registered, after the respective registration statement
shall have become effective, shall be treated as an "effective" registration for
purposes of this Agreement.

          1.055.  Termination of Restrictions.  Notwithstanding the foregoing
                  ---------------------------
provisions of this Section 5, the restrictions imposed upon the transferability
                   ---------
of the Restricted Stock shall cease and terminate as to any particular
Restricted Security when such Restricted Security shall have been effectively
registered under the Securities Act and sold by the holder thereof in accordance
with such registration or the holder of such Restricted Security has delivered
to the Company an opinion of counsel in form and substance reasonably
satisfactory to the Company that all of the Restricted Stock may simultaneously
be sold in accordance with the safe harbor provisions of Rule 144(k).  No
request for registration may be made by a holder of Restricted Stock pursuant to
this Section 5, nor may any registration be required to be maintained if such
     ---------
holder of Restricted Stock is advised by the Company, and promptly furnished an
opinion of the Company's counsel reasonably satisfactory to such holder, to the
effect that all of the shares of Restricted Stock subject to registration under
this Agreement are eligible for simultaneous sale under the conditions of Rule

                                      -22-
<PAGE>
 
144 as promulgated by the Commission, and no request for registration may be
made with respect to such shares of Restricted Stock to which such opinion is
applicable, and no registration need be maintained in respect thereof under
either such circumstance.  Whenever the restrictions imposed shall terminate as
to a Restricted Certificate, as hereinabove provided, the holder thereof shall
be entitled to receive from the Company, without expense, a new certificate not
bearing the restrictive legend otherwise required to be borne thereby.

          1.056.  Rule 144 and 144A.  In order to permit the holders of
                  -----------------
Restricted Securities to sell the same, if they so desire, pursuant to Rule 144
or Rule 144A promulgated by the Commission (or any successors to such rules),
the Company will comply with all rules and regulations of the Commission
applicable in connection with use of each of Rule 144 and Rule 144A (or any
successors thereto), including the timely filing of all reports with the
Commission and the provision of any information regarding the Company in order
to enable such holders, if they so elect, to utilize Rule 144 or Rule 144A, and
the Company will cause any restrictive legends to be removed and any transfer
restrictions to be rescinded with respect to any sale of Warrant Stock which is
exempt from registration under the Securities Act pursuant to Rule 144 or Rule
144A. Upon the request of any holder of Restricted Securities, the Company will
deliver to such holder a written statement verifying that it has complied with
such requirements.

          1.057.  Indemnification.
                  --------------- 

          (a)  In the event of any registration of any of its securities under
the Securities Act pursuant to this Section 5, the Company shall indemnify and
                                    ---------
hold harmless the Seller of such Restricted Stock, its directors and officers,
and each other Person, if any, who controls such Seller within the meaning of
the Securities Act ("Controlling Person"), against any losses, claims, damages
                     ------------------
or liabilities, joint or several, to which such Seller or any such director or
officer or Controlling Person may become subject under the Securities Act or any
other statute or at common law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are

                                      -23-
<PAGE>
 
based upon (i) any alleged untrue statement of any material fact contained, on
the effective date thereof, in any registration statement under which such
securities were registered under the Securities Act, or in any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereto, (ii) any alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading or
(iii) any violation by the Company of any rule or regulation promulgated under
the Securities Act or the Exchange Act, or other federal or state law applicable
to the Company and relating to any action or inaction required of the Company in
connection with such registration, and shall reimburse such Seller or such
director, officer or Controlling Person for any reasonable legal or any other
expenses reasonably incurred by such Seller or such director, officer or
Controlling Person in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Company shall
                                    --------  -------                        
not be liable in any such case to the extent that any such loss, claim, damage
or liability arises out of or is based upon any alleged untrue statement or
alleged omission made in such registration statement, preliminary prospectus,
prospectus, or amendment or supplement in reliance upon and in conformity with
written information furnished to the Company by such Seller, by any underwriter
in the transaction or by such Controlling Person specifically for use therein;
and provided further, however, that the Company shall not be liable hereunder to
any underwriter or any person who controls an underwriter within the meaning of
the Securities Act and the Exchange Act for any claim, damage or liability that
is based upon any untrue statement or alleged untrue statement or any omission
contained in any preliminary prospectus that was corrected by any subsequent
prospectus, and the underwriter was required to deliver but failed to deliver
such prospectus as required by the Securities Act.  Such indemnity shall remain
in full force and effect regardless of any investigation made by or on behalf of
such Seller or such director, officer or Controlling Person, and shall survive
the transfer of such securities by such Seller.

          (b)  Each holder of any Restricted Stock shall, by acceptance thereof,
severally and not jointly, indemnify and hold

                                      -24-
<PAGE>
 
harmless the Company, its directors and officers and each other Person, if any,
who controls the Company against any losses, claims, damages or liabilities,
joint or several, to which the Company or any such director or officer or any
such Person may become subject under the Securities Act or any other statute or
at common law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon (i) any alleged
untrue statement of any material fact contained, on the effective date thereof,
in any registration statement under which Restricted Stock was registered under
the Securities Act, or in any preliminary prospectus or final prospectus
contained therein, or any amendment or supplement thereto, or (ii) any alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent that such alleged untrue statement or alleged
omission was contained in written information furnished to the Company by such
holder specifically for use therein, and shall reimburse the Company or such
director, officer or other Person for any legal or any other expenses reasonably
incurred in connection with investigating or defending any such loss, claim,
damage, liability or action. Notwithstanding the foregoing, obligations of any
holder shall be limited to an amount equal to the proceeds to such holder from
the Restricted Stock sold pursuant to the registration statement to which the
losses, claims, liabilities or damages related.

          (c)  Indemnification similar to that specified in clauses (a) and (b)
of this Section 5.07 shall be given by the Company and each holder of any
        ------------
Restricted Certificate (with such modifications as shall be appropriate) to each
other and to any underwriter with respect to any required registration or other
qualification of any Restricted Stock under any federal or state law or
regulation of governmental authority other than the Securities Act.  The
indemnity and expense reimbursement obligations of the Company under clause (a)
of this Section 5.07 shall be in addition to any liability the Company may
        ------------
otherwise have.

          (d)  Each Person ("Indemnitor") who under the preceding provisions of
                             ----------
this Section 5.07 agrees to indemnify 
     ------------

                                      -25-
<PAGE>
 
another Person ("Indemnitee") shall have the right, subject to the provisions
                 ----------
hereto, to designate counsel (reasonably acceptable to the Indemnitee) to defend
any case or proceeding against the Indemnitee arising in respect of any claim of
liability for which such indemnification may be claimed, to the end that
duplication of legal expense may be minimized; provided that, if the Indemnitee
notifies the Indemnitor that the Indemnitee has reasonably concluded and has
been advised by its counsel that any single counsel in such case or proceeding
would have a conflict of interest in representing both the Indemnitor and the
Indemnitee, the Indemnitee may designate its own counsel in such case or
proceeding and, to the extent so provided above in this Section 5.07, shall be
                                                        ------------
entitled to be reimbursed by the Indemnitor for the Indemnitee's legal expenses
reasonably incurred in connection with defending itself in such case or
proceeding. Each Indemnitee may engage legal counsel at the Indemnitor's expense
if the Indemnitor shall fail to perform hereunder.

          1.058.  Miscellaneous Registration Provisions.
                  -------------------------------------

          (a)  Without limiting in any way any of the rights the holders of the
Restricted Securities may otherwise have at law or in equity, for damages or
otherwise, the Company hereby agrees to indemnify and hold harmless each holder
of Restricted Securities from and against any loss or expense that may be
incurred or suffered by such holder which arises from any of the following:  (i)
a registration statement is not filed with the Commission on or before the time
required in Section 5.01 or (ii) the Company does not use its best efforts to
            ------------
cause such registration statement to be declared effective by the Commission at
the time reasonably requested by the underwriters and to remain effective until
completion of the offering of the Restricted Securities, or to cause the
Restricted Securities to be qualified or registered for sale in all appropriate
jurisdictions as provided in Section 5.03(e) and to remain so qualified or
                             ---------------
registered thereafter during the applicable period under applicable law.

          (b)  Each holder of Restricted Securities, in addition to being
entitled to exercise all rights provided herein

<PAGE>
 
or granted by law, including recovery of damages, will be entitled to specific
performance of its rights under this Warrant. The Company agrees that monetary
damages would not be adequate compensation for any loss incurred by reason of a
breach by the Company hereof and hereby agrees to waive the defense in any
action for specific performance that a remedy at law would be adequate.

          (c)  The Company will not on or after the date hereof enter into, any
agreement with respect to its securities which is inconsistent with the terms
hereof, including any agreement which impairs or limits the registration rights
granted to the holder of Restricted Securities or which otherwise conflicts with
the provisions hereof or would preclude the Company from discharging its
obligations hereunder, without the prior written consent of the holders of at
least a majority of the Restricted Stock.

manner and circumstances of the proposed Transfer, and shall obtain from legal
counsel to such holder, an opinion that the proposed Transfer of such Warrants
or such Warrant Stock may be effected without registration under the Securities
Act or any other federal or state securities laws. After receipt of the Transfer
Notice and legal opinion, the Company shall, within five (5) days thereof,
notify the holder of such Warrants or such Warrant Stock as to whether such
opinion is reasonably satisfactory, or if the Company does not so notify such
holder within such five (5) day period, such holder shall thereupon be entitled
to effect such Transfer of such Warrants or such Warrant Stock, in accordance
with the terms of the Transfer Notice. The Company shall have no obligation to
register any Warrants under the Securities Act or any other federal or state
securities laws.

          WP = Current Warrant Price

          WS =  The number of shares of Warrant Stock issuable upon exercise of

shall be endorsed with a legend as set forth in Section 1.03 to the Warrant
Agreement and shall be in such denominations as may be specified in said notice
and shall be registered in the name of such holder or such other name or names
as shall be designated in said notice.  Such certificate or certificates shall
be deemed to have been issued and such holder or any other Person so designated
to be named therein shall be deemed to have become a holder of record of such
shares, including to the extent permitted by law the right to vote such shares
or to consent or to receive notice as a stockholder, as of the time said notice
is received by the Company as aforesaid.

          Except as otherwise provided in (S) 8 hereof, the Company shall pay
all expenses, transfer taxes and other charges payable in connection with the
preparation, issue and delivery of stock certificates under this (S) 2, except
that, in case such stock certificates shall be registered in a name or names

stock transfer taxes which shall be payable upon the issuance of such stock
certificate or certificates shall be paid by the holder hereof at the time of
delivering the notice of exercise mentioned above.

          All shares of Warrant Stock issuable upon the exercise of this Warrant
shall be validly issued, fully paid and nonassessable, and free from all liens
and other encumbrances thereon.

          The Company will not close its books against the transfer of this
Warrant or of any share of Warrant Stock in any manner which interferes with the

day of delivery of notice of exercise to the Company shall be paid to the holder
of this Warrant in cash by the Company.

     (S) 3.    Transfer, Division and Combination.  Subject to (S) 11, this

Warrant at the office of the Company maintained for such purpose pursuant to (S)
16, together with a written assignment of this Warrant duly executed by the
holder hereof or its agent or attorney and payment of funds sufficient to pay

surrender and payment the Company shall, subject to (S) 11, execute and deliver
a new Warrant or Warrants in the name of the assignee or assignees and in the
denominations specified in such instrument of assignment, and this Warrant shall
promptly be cancelled.  If and when this Warrant is assigned in blank (in case
the restrictions on transferability in (S) 11 shall have been terminated), the
Company may (but shall not be obliged to) treat the bearer hereof as the
absolute owner of this Warrant for all purposes and the Company shall not be
affected by any notice to the contrary.  This Warrant, if properly assigned in
compliance with this (S) 3 and (S) 11, may be exercised by an assignee for the
purchase of shares of Common Stock without having a new Warrant issued.

          This Warrant may, subject to (S) 11, be divided or combined with other
Warrants upon presentation at the aforesaid office of the Company, together with

to compliance with the preceding paragraph and with (S) 11, as to any transfer
which may be involved in such division or combination, the Company shall execute
and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to
be divided or combined in accordance with such notice.

registration and transfer of the Warrants.

     (S) 4.    Adjustment of Stock Unit.  The number of shares of Common Stock
               ------------------------                                       
comprising a Stock Unit shall be subject to adjustment from time to time as set
forth in this (S)4 with respect to any fact or event described herein occurring
after the date hereof.  The Company will not take any action with respect to its
Nonpreferred Stock of any class requiring an adjustment pursuant to any of the
following Subsections A, B, or H without at the same time taking like action
          ----------- -  -     -                                            
with respect to its Nonpreferred Stock of each other class; and the Company will
not create any class of Nonpreferred Stock which carries any rights to dividends
or assets differing in any respect from the rights of the Common Stock on the
date hereof.  Anything contained in this (S) 4 notwithstanding, any adjustment
made pursuant to any provision of this (S) 4 shall be made without duplication
of an adjustment otherwise required by and made pursuant to another provision of
this (S) 4 on account of the same facts or events.

          A.   Stock Dividends, Subdivisions and Combinations. In case at any
               ----------------------------------------------                
time or from time to time the Company shall:

               (1) take a record of the holders of its Nonpreferred Stock for
     the purpose of entitling them to receive a dividend payable in, or other
     distribution of, Nonpreferred Stock, or

               (2) subdivide its outstanding shares of Nonpreferred Stock into a
     larger number of shares of Nonpreferred Stock, or

                                      -10-
<PAGE>
 
               (3) combine its outstanding shares of Nonpreferred Stock into a
     smaller number of shares of Nonpreferred Stock,

then the number of shares of Common Stock comprising a Stock Unit immediately
after the happening of any event described in clauses (1) through (3) above
                                              -----------------------      
shall be adjusted so as to consist of the number of shares of Common Stock which
a record holder of the number of shares of Common Stock constituting a Stock
Unit immediately prior to the happening of such event would own or be entitled
to receive after the happening of event described in clauses (1) through (3)
                                                     -----------------------
above.

          B.   Certain Other Dividends and Distributions.  In case at any time
               -----------------------------------------                      
or from time to time the Company shall take a record of the holders of its
Nonpreferred Stock for the purpose of entitling them to receive any dividend or
other distribution of:

               (1) cash (other than a cash distribution made as a dividend and
     payable out of earnings or earned surplus legally available for the payment
     of dividends under the laws of the jurisdiction of incorporation of the
     Company), or

               (2) any evidence of its indebtedness (other than Convertible
     Securities) or any other property of any nature whatsoever (other than cash
     and other than Convertible Securities or Additional Shares of Nonpreferred
     Stock), or

               (3) any warrants, options or other rights to subscribe for or
     purchase (i) any evidences of its indebtedness (other than Convertible
     Securities), (ii) any shares of its stock (other than Additional Shares of
     Nonpreferred Stock) or (iii) any other property of any nature whatsoever
     (other than cash and other than Convertible Securities or Additional Shares
     of Nonpreferred Stock),

then the number of shares of Common Stock thereafter comprising a Stock Unit
shall be adjusted to that number determined by 

                                      -11-
<PAGE>
 
multiplying the number of shares of Common Stock comprising a Stock Unit
immediately prior to such adjustment by a fraction (i) the numerator of which
shall be the Current Market Price per share of Common Stock at the date of
taking such record, and (ii) the denominator of which shall be such Current
Market Price per share of Common Stock minus the portion applicable to one share
of Common Stock of any such cash so distributable (if any) and of the fair value
of any and all such evidences of indebtedness, other property, or warrants,
options or other subscription or purchase rights, so distributable (if any).
Such fair value shall be determined in good faith by the Board of Directors of
the Company, provided that if such determination is objected to by the holders
of Warrants entitled to purchase a majority of the Stock Units covered thereby,
such determination shall be made by an independent appraiser selected by such
Board of Directors and not objected to by such holders. The Company and the
Holders shall each pay one-half of the fees and expenses of such appraiser. A
reclassification (other than a change in par value) of the Nonpreferred Stock
into shares of Nonpreferred Stock and shares of any other class of stock shall
be deemed a distribution by the Company to the holders of its Nonpreferred Stock
of such shares of such other class of stock within the meaning of this
Subsection and, if the outstanding shares of Nonpreferred Stock shall be changed
into a larger or smaller number of shares of Nonpreferred Stock as a part of
such reclassification, shall be deemed a subdivision or combination, as the case
may be, of the outstanding shares of Nonpreferred Stock within the meaning of
Subsection A of this (S) 4.

          C.   Issuance of Additional Shares of Nonpreferred Stock.  In case at

any time or from time to time the Company shall (except as hereinafter provided)
issue, whether in connection with the merger of a corporation into the Company
or otherwise, any Additional Shares of Nonpreferred Stock for a consideration
per share less than the Current Warrant Price per share of Common Stock, then
the number of shares of Common Stock thereafter comprising a Stock Unit shall be
adjusted to be the greater of (A) that number determined by multiplying the
number of shares of Common Stock comprising a Stock Unit immediately prior to
such adjustment by a fraction (i) the numerator of which shall be the Current
Warrant Price per share of Common Stock, and 

                                      -12-
<PAGE>
 
(ii) the denominator of which shall be the consideration per share received by
the Company for such Additional Shares of Nonpreferred Stock or (B) that number
determined by multiplying the number of shares of Common Stock comprising a
Stock Unit immediately prior to such adjustment by a fraction (i) the numerator
of which shall be the number of shares of Nonpreferred Stock outstanding
immediately prior to such issuance, plus the number of such Additional Shares of
Nonpreferred Stock so issued, and (ii) the denominator of which shall be the
number of shares of Nonpreferred Stock immediately prior to such issuance, plus
the number of shares of Nonpreferred Stock which the aggregate consideration for
the total number of such Additional Shares of Nonpreferred Stock would purchase
at the Current Warrant Price. For purposes of this Subsection, the date as of
which the Current Warrant Price shall be computed shall be the earlier of (a)
the date on which the Company shall enter into a firm contract for the issuance
of such Additional Shares of Nonpreferred Stock, or (b) the date of actual
issuance of such Additional Shares of Nonpreferred Stock. The provisions of this
Subsection shall not apply to any issuance of Additional Shares of Nonpreferred
Stock for which an adjustment is provided under Subsection A of this (S) 4. No
                                                ------------
adjustment of the number of shares of Common Stock comprising a Stock Unit shall
be made under this Subsection upon the issuance of any Additional Shares of
Nonpreferred Stock which are issued pursuant to the exercise of any warrants,
options or other subscription or purchase rights or pursuant to the exercise of
any conversion or exchange rights in any Convertible Securities, if any such
adjustment shall previously have been made upon the issuance of such warrants,
options or other rights or upon the issuance of such Convertible Securities (or
upon the issuance of any warrants, options or other rights therefor) pursuant to
Subsection D or E of this (S) 4.

               ---------------------------------------------                 
time or from time to time the Company shall take a record of the holders of its
Nonpreferred Stock for the purpose of entitling them to receive a distribution
of, or shall otherwise issue, any warrants, options or other rights to subscribe
for or purchase any Additional Shares of Nonpreferred Stock or any Convertible
Securities and the consideration per share for which Additional Shares of
Nonpreferred Stock may at

any time thereafter be issuable pursuant to such warrants, options or other
rights or pursuant to the terms of such Convertible Securities shall be less
than the Current Warrant Price per share of Common Stock, then the number of
shares of Common Stock thereafter comprising a Stock Unit shall be adjusted to
be the number determined pursuant to the first sentence of Subsection C of this
                                                           ------------

                                             ------------   
basis that (i) the maximum number of Additional Shares of Nonpreferred Stock
issuable pursuant to all such warrants, options or other rights or necessary to
effect the conversion or exchange of all such Convertible Securities shall be
deemed to have been issued as of the date specified in the last sentence of this
Subsection, (ii) the aggregate consideration for such maximum number of
Additional Shares of Nonpreferred Stock shall be deemed to be the consideration
received and receivable by the Company for the issuance of such Additional
Shares of Nonpreferred Stock pursuant to such warrants, options or other rights
or pursuant to the terms of such Convertible Securities and (iii) the
consideration per share received by the Company for such Additional Shares of
Nonpreferred Stock shall be that number determined by dividing (x) the aggregate
consideration for such maximum number of Additional Shares of Nonpreferred Stock
(determined as set forth in clause (ii) of this sentence) by (y) the maximum
number of Additional Shares of Nonpreferred Stock issuable pursuant to all such
warrants, options or other rights or necessary to effect the conversion or
exchange of all such Convertible Securities (determined as set forth in clause
(i) of this sentence). For purposes of this Subsection, the computation date for
subclause (i) above and as of which the Current Warrant Price shall be computed
shall be the earliest of (a) the date on which the Company shall take a record
of the holders of its Nonpreferred Stock for the purpose of entitling them to
receive any such warrants, options or other rights, (b) the date on which the
Company shall enter into a firm contract for the issuance of such warrants,
options or other rights, and (c) the date of actual issuance of such warrants,
options or other rights.

               ----------------------------------                              
time to time the Company shall take a record of the holders of its Nonpreferred
Stock for the purpose of

<PAGE>
 
entitling them to receive a distribution of, or shall otherwise issue, any
Convertible Securities and the consideration per share for which Additional
Shares of Nonpreferred Stock may at any time thereafter be issuable pursuant to
the terms of such Convertible Securities shall be less than the Current Warrant
Price per share of Common Stock, then the number of shares of Common Stock
thereafter comprising a Stock Unit shall be adjusted to be the number determined
pursuant to the first sentence of Subsection C of this (S) 4. All adjustments
                                   ------------
made pursuant to this Subsection E shall be made on the basis that (i) the
                      ------------
maximum number of Additional Shares of Nonpreferred Stock necessary to effect
the conversion or exchange of all such Convertible Securities shall be deemed to
have been issued as of the computation date specified in the penultimate
sentence of this Subsection, (ii) the aggregate consideration for such maximum
number of Additional Shares of Nonpreferred Stock shall be deemed to be the
consideration received and receivable by the Company for the issuance of such
Additional Shares of Nonpreferred Stock pursuant to the terms of such
Convertible Securities and (iii) the consideration per share received by the
Company for such Additional Shares of Nonpreferred Stock shall be that number
determined by dividing (x) the aggregate consideration for such maximum number
of Additional Shares of Nonpreferred Stock (determined as set forth in clause
(ii) of this sentence) by (y) the maximum number of Additional Shares of
Nonpreferred Stock necessary to effect the conversion or exchange of all such
Convertible Securities (determined as set forth in clause (i) of this sentence).
For purposes of this Subsection, the computation date for clause (i) above and
as of which the Current Warrant Price shall be computed shall be the earliest of
(a) the date on which the Company shall take a record of the holders of its
Nonpreferred Stock for the purpose of entitling them to receive any such
Convertible Securities, (b) the date on which the Company shall enter into a
firm contract for the issuance of such Convertible Securities, and (c) the date
of actual issuance of such Convertible Securities. No adjustment of the number
of shares of Common Stock comprising a Stock Unit shall be made under this
Subsection upon the issuance of any Convertible Securities which are issued
pursuant to the exercise of any warrants, options or other subscription or
purchase rights therefor, if any such adjustment shall previously have been made
upon the issuance of such warrants, options or other rights pursuant to
Subsection D of this (S) 4.

          F.   Superseding Adjustment of Stock Unit.  If, at any time after any
               ------------------------------------                            
adjustment of the number of shares of Common Stock comprising a Stock Unit shall
have been made pursuant to the foregoing Subsection D or E of this (S) 4 on the
                                         ------------    -                     
basis of the issuance of warrants, options or other rights or the issuance of
other Convertible Securities, or after any new adjustment of the number of
shares of Common Stock comprising a Stock Unit shall have been made pursuant to
this Subsection,

               (1) such warrants, options or rights or the right of conversion
     or exchange in such other Convertible Securities shall expire, and a
     portion or all of such warrants, options or rights, or the right of
     conversion or exchange in respect of a portion of such other Convertible
     Securities, as the case may be, shall not have been exercised, or

               (2) the consideration per share for which Additional Shares of
     Nonpreferred Stock are issuable pursuant to such warrants, options or
     rights or the terms of such other Convertible Securities, shall be
     increased solely by virtue of provisions therein contained for an automatic
     increase in such consideration per share upon the arrival of a specified
     date or the happening of a specified event,

such previous adjustment shall be rescinded and annulled and the Additional
Shares of Nonpreferred Stock which were deemed to have been issued by virtue of
the computation made in connection with the adjustment so rescinded and annulled
shall no longer be deemed to have been issued by virtue of such computation.
Thereupon, a recomputation shall be made of the effect of such warrants, options
or rights or other Convertible Securities on the basis of:

               (3) treating the number of Additional Shares of Nonpreferred
     Stock, if any, theretofore actually issued or issuable pursuant to the
     previous exercise of such warrants, options or rights or such right of
     conversion or exchange,

                                      -16-
<PAGE>
 
     as having been issued on the date or dates of such issuance as determined
     for purposes of such previous adjustment and for the consideration actually
     received and receivable therefor, and

               (4) treating any such warrants, options or rights or any such
     other Convertible Securities which then remain outstanding as having been
     granted or issued immediately after the time of such expiration or of such
     increase of the consideration per share for which such Additional Shares of
     Nonpreferred Stock are issuable under such warrants, options or rights or
     other Convertible Securities, at the increased per share consideration,

and, if and to the extent called for by the foregoing provisions of this (S) 4
on the basis aforesaid, a new adjustment of the number of shares of Common Stock
comprising a Stock Unit shall be made, which new adjustment shall supersede the
previous adjustment so rescinded and annulled.

          G.   Other Provisions Applicable to Adjustments Under this Section.
               -------------------------------------------------------------  
The following provisions shall be applicable to the making of adjustments of the
number of shares of Common Stock comprising a Stock Unit hereinbefore provided
for in this (S) 4:

               (1) Treasury Stock.  The sale or other disposition of any issued
                   --------------                                              
     shares of Nonpreferred Stock, other than any Additional Shares of
     Nonpreferred Stock, owned or held by or for the account of the Company
     shall be deemed an issuance thereof for purposes of this (S) 4.

               (2) Computation of Consideration.  To the extent that any
                   ----------------------------                         
     Additional Shares of Nonpreferred Stock or any Convertible Securities or
     any warrants, options or other rights to subscribe for or purchase any
     Additional Shares of Nonpreferred Stock or any Convertible Securities shall
     be issued solely for cash consideration, the consideration received by the
     Company therefor shall be deemed to be the amount of cash received by the
     Company therefor, or, if such Additional Shares of Nonpreferred Stock or
     Convertible Securities are offered by the Company for subscription, the

                                      -17-
<PAGE>
 
     subscription price, or, if such Additional Shares of Nonpreferred Stock or
     Convertible Securities are sold to underwriters or dealers for public
     offering without a subscription offering, the initial public offering
     price, in any such case excluding any amounts paid or receivable for
     accrued interest or accrued dividends and without deduction of any
     compensation, discounts or expenses paid or incurred by the Company for and
     in the underwriting of, or otherwise in connection with, the issue thereof.
     To the extent that such issuance shall be for a consideration other than
     solely for cash, then, except as herein otherwise expressly provided, the
     amount of such consideration shall be deemed to be the fair value of such
     consideration at the time of such issuance as determined in good faith by
     the Board of Directors of the Company, provided that if such determination
     is objected to by the holders of  Warrants entitled to purchase a majority
     of the Stock Units covered thereby, such determination shall be made by an
     independent appraiser selected by such Board of Directors and not objected
     to by such holder.  The Company, on the one hand, and the holders of
     Warrants, on the other, shall each pay one-half of the fees and expenses of
     such appraiser.  The consideration for any Additional Shares of
     Nonpreferred Stock issuable pursuant to any warrants, options or other
     rights to subscribe for or purchase the same shall be the consideration
     received or receivable by the Company for issuing such warrant, options or
     other rights, plus the additional consideration payable to the Company upon
     the exercise of such warrants, options or other rights.  The consideration
     for any Additional Shares of Nonpreferred Stock issuable pursuant to the
     terms of any Convertible Securities shall be the consideration received or
     receivable by the Company for issuing any warrants, options or other rights
     to subscribe for or purchase such Convertible Securities (if any), plus the
     consideration paid or payable to the Company in respect of the subscription
     for or purchase of such Convertible Securities, plus the additional
     consideration, if any, payable to the Company upon the exercise of the
     right of conversion or exchange in such Convertible Securities.

               (3) When Adjustments To Be Made.  The adjustments required by the
                   ---------------------------                                  
     preceding Subsections of this (S) 4 shall be made whenever and as often as
     any specified event requiring an adjustment shall occur, except that no
     adjustment of the number of shares of Common Stock comprising a Stock Unit
     that would otherwise be required shall be made (except in the case of a
     subdivision or combination of shares of the Nonpreferred Stock, as provided
     for in Subsection A) unless and until such adjustment, either by itself or
            ------------                                                       
     with other adjustments not previously made, adds or subtracts at least
     $0.005 to the Current Warrant Price per share of Common Stock, as
     determined in good faith by the Board of Directors of the Company, provided
     that, in any event such adjustment shall be made if such adjustment either
     by itself or with other adjustments not previously made adds or subtracts
     at least 1/20th of a share to or from the number of shares of Common Stock
     comprising a Stock Unit immediately prior to the making of such adjustment.
     Any adjustment representing a change of less than such minimum amount
     (except as aforesaid) shall be carried forward and made as soon as such
     adjustment, together with other adjustments required by this (S) 4 and not
     previously made, would result in a minimum adjustment.  For the purpose of
     any adjustment, any specified event shall be deemed to have occurred at the
     close of business on the date of its occurrence.

               (4) Fractional Interests.  In computing adjustments under this
                   --------------------                                      
     Section, fractional interests in Non  preferred Stock shall be taken into
     account to the nearest 1/100th of a share.

               (5) When Adjustment Not Required.  If the Company shall take a
                   ----------------------------                              
     record of the holders of its Nonpreferred Stock for the purpose of
     entitling them to receive a dividend or distribution or subscription or
     purchase rights and shall, thereafter and before the distribution thereof
     to shareholders, legally abandon its plan to pay or deliver such dividend,
     distribution, subscription or purchase rights, then thereafter no
     adjustment shall be required by reason of the taking of such record and any
     such adjustment previously made in respect thereof shall be rescinded and
     annulled.

                                      -19-
<PAGE>
 
          H.   Merger, Consolidation or Disposition of Assets. In case the
               ----------------------------------------------             
Company shall merge or consolidate into another corporation and the Company is
not the surviving entity, or the Company shall sell, transfer or otherwise
dispose of all or substantially all of its property, assets or business to
another corporation, then each holder of a Warrant (regardless of whether this
Warrant is then exercisable) shall have the right to receive notice from the
Company of such merger, consolidation or disposition at least forty-five (45)
days prior to the closing of such merger, consolidation or disposition, which
notice shall include a copy of the operative merger, consolidation or
disposition documents or a summary of their operative terms and shall include a
statement from the surviving or acquiring entity that it does not wish to assume
the Company's obligations under this Warrant.  Thereafter, the holder of this
Warrant shall have until ten (10) days prior to the closing date of the merger,
consolidation or disposition, to exercise this Warrant and participate in such
merger, consolidation or disposition on the terms negotiated by the Company,
regardless of whether this Warrant had yet become exercisable in accordance with
its terms. If this Warrant is not then exercised, it shall terminate effective
as of the closing date of such merger, consolidation or disposition.

          I.   Other Action Affecting Nonpreferred Stock.  In case at any time
               -----------------------------------------                      
or from time to time the Company shall take any action affecting its
Nonpreferred Stock, other than an action described in any of the foregoing
Subsections A to H, inclusive, of this (S) 4 and the actions described in
- -------------    -                                                       
clauses (i) through (viii) of the definition of Additional Shares of
Nonpreferred Stock, then, unless in the reasonable opinion of the Board of
Directors of the Company such action will not have a materially adverse effect
upon the rights of the holders of the Warrants, the number of shares of Common
Stock or other stock comprising a Stock Unit, or the purchase price thereof,
shall be adjusted in such manner and at such time as the Board of Directors of
the Company may in good faith determine to be equitable in the circumstances.

                                      -20-

          J.   No Adjustments for Certain Transactions.  Anything contained in
               ---------------------------------------                        
this Warrant notwithstanding, the number of shares of Common Stock comprising a
Stock Unit and the Purchase Price per Stock Unit shall not be adjusted, nor be
subject to adjustment, on account of the granting of any rights under a phantom
stock plan, stock appreciation rights plan or other deferred compensation plan
to officers, directors or employees of the Company or its affiliates, and (i) no
shares of Nonpreferred Stock are issued or required to be issued under any such
plan and (ii) the only consideration paid or payable to any participant in such
plan is cash.

          K.   Special Adjustments for Certain Transactions. Anything contained
               --------------------------------------------                    
in this Warrant notwithstanding, if any Affiliate of the Company that owns ten
percent (10%) or more of the Common Stock of the Company (calculated on a fully-
diluted basis) sells or otherwise transfers (other than to a family member or
trust for tax planning purposes or to an Affiliate of such Person) in the
aggregate more than 1,000,000 shares of Common Stock or an equivalent number of
shares of the Company's capital stock which is convertible into Common Stock (in
such case based on the number of shares of Common Stock for which such share is
then convertible) at a price less than the Current Warrant Price, then such sale
or transfer shall be deemed an issuance by the Company of Additional Shares of
Nonpreferred Stock under (S) 4.C hereof and shall be subject to the adjustments
set forth therein.  The consideration for such sale or transfer under this (S)
4.K, for purposes of the adjustments to be made pursuant to (S) 4.C, shall be
equal to the average weighted sale price per share of Common Stock sold (or in
the case of shares of the Company's capital stock other than Common Stock, on
the sale price per share of Common Stock then underlying such share sold).

     (S) 5.    Notice to Warrant Holders.
               ------------------------- 

               A. Notice of Adjustment of Stock Unit or Purchase Price. Whenever
                  ----------------------------------------------------
the number of shares of Warrant Stock comprising a Stock Unit or the Purchase
Price per Stock Unit shall be adjusted pursuant to (S) 4, the Company shall
forthwith obtain a certificate signed by the president of the Company, the
principal 

                                      -21-
<PAGE>
 
financial officer of the Company and independent accountants, of recognized
national standing, then engaged by the Company and reasonably acceptable to the
holders of a majority of the Warrants, setting forth, in reasonable detail, the
event requiring the adjustment and the method by which such adjustment was
calculated (including a statement of the fair value, as determined by the Board
of Directors of the Company, of any evidences of indebtedness, shares of stock,
other securities or property or warrants, options or other subscription or
purchase rights referred to in (S) 4.B, (S) 4.G(2) or (S) 4.H) and specifying
the number of shares of Common Stock comprising a Stock Unit and (if such
adjustment was made pursuant to (S) 4.H or (S) 4.I) describing the number and
kind of any other shares of stock comprising a Stock Unit, and any change in the
Purchase Price thereof after giving effect to such adjustment or change. The
Company shall promptly, and in any case within 30 days after the making of such
adjustment, cause a signed copy of such certificate to be delivered to each
holder of a Warrant in accordance with (S) 16. The Company shall keep at its
office or agency, maintained for the purpose pursuant to (S) 16, copies of all
such certificates and cause the same to be available for inspection at said
office during normal business hours by any holder of a Warrant or any
prospective purchaser of a Warrant designated by a holder thereof.

          B.   Notice of Certain Corporate Action.  In case the Company shall
               ----------------------------------                            
propose (a) to pay any dividend payable in cash or in stock of any class to the
holders of its Nonpreferred Stock or to make any other distribution to the
holders of its Nonpreferred Stock, or (b) to offer to the holders of its
Nonpreferred Stock rights to subscribe for or to purchase any Additional Shares
of Nonpreferred Stock or shares of stock of any class or any other securities,
rights or options, or (c) to effect any reclassification of its Nonpreferred
Stock (other than a reclassification involving only the subdivision or
combination of outstanding shares of Nonpreferred Stock), or (d) to effect any
capital reorganization, or (e) to effect any consolidation, merger or sale,
change to the Company's charter, transfer or other disposition of all or
substantially all of its property, assets or business, or (f) to effect the
liquidation, dissolution or winding up of the Company, then in each such case,
the Company 

                                      -22-
<PAGE>
 
shall give to each holder of a Warrant, in accordance with (S) 17, a notice,
certified by the president of the Company and the principal financial officer of
the Company, of such proposed action, which shall specify the date on which a
record is to be taken for the purposes of such stock dividend, distribution or
rights, or the date on which such reclassification, reorganization,
consolidation, merger, sale, change to the Company's charter, transfer,
disposition, liquidation, dissolution, or winding up is to take place and the
date of participation therein by the holders of Nonpreferred Stock, if any such
date is to be fixed, and shall also set forth such facts with respect thereto as
shall be reasonably necessary to indicate the effect of such action on the
Nonpreferred Stock and the number and kind of any other shares of stock which
will comprise a Stock Unit, and the purchase price or prices thereof, after
giving effect to any adjustment which will be required as a result of such
action. Such notice shall be so given in the case of any action covered by
clause (a) or (b) above at least ten days prior to the record date for
determining holders of the Nonpreferred Stock for purposes of such action, and
in the case of any other such action, at least twenty days prior to the date of
the taking of such proposed action or the date of participation therein by the
holders of Nonpreferred Stock, whichever shall be the earlier.

  (S) 6.  Reservation and Authorization of Nonpreferred Stock; Registration
          -----------------------------------------------------------------
with or Approval of any Governmental Authority.  The Company shall at all times
- ----------------------------------------------                                 
reserve and keep available for issue upon the exercise of Warrants such number
of its authorized but unissued shares of Common Stock as will be sufficient to
permit the exercise in full of all outstanding Warrants.  All shares of Common
Stock which shall be so issuable, when issued upon exercise of any Warrant or
upon such conversion, as the case may be, shall be duly and validly issued and
fully-paid and nonassessable.

          Before taking any action which would cause an adjustment reducing the
Current Warrant Price per share of Common Stock below the then par value, if
any, of the shares of Common Stock issuable upon exercise of the Warrants, the
Company shall take any corporate action which may, in the opinion of its

                                      -23-
<PAGE>
 
counsel, be necessary in order that the Company may validly and legally issue
fully-paid and nonassessable shares of Common Stock at such adjusted Current
Warrant Price.

          Before taking any action which would result in an adjustment in the
number of shares of Common Stock comprising a Stock Unit or in the Current
Warrant Price per share of Common Stock, the Company shall obtain all such
authorizations or exemptions thereof, or consents thereto, as may be necessary
from any public regulatory body or bodies having jurisdiction thereof (except
that nothing contained in this Warrant certificate shall require the Company to
register the Warrants under the Securities Act or any similar federal or state
equivalent).

     (S) 7.    Taking of Record; Stock and Warrant Transfer Books.  In the case
               --------------------------------------------------              
of all dividends or other distributions by the Company to the holders of its
Nonpreferred Stock with respect to which any provision of (S) 4 refers to the
taking of a record of such holders, the Company will in each such case take such
a record and will take such record as of the close of business on a Business
Day.  The Company will not at any time, except (i) upon dissolution, liquidation
or winding up, or (ii) for purposes of declaring and paying a dividend or
matters related to voting by shareholders of the Company, close its stock
transfer books or Warrant transfer books so as to result in preventing or
delaying the exercise or transfer of any Warrant.

     (S) 8.    Transfer Taxes.  The Company will pay any and all transfer taxes
               --------------                                                  
that may be payable in respect of the issuance or delivery of shares of Common
Stock on exercise of this Warrant. The Company shall not, however, be required
to pay any tax which may be payable in respect of any transfer involved in the
issue and delivery of shares of Common Stock in a name other than that in which
this Warrant is registered, and no such issue or delivery shall be made unless
and until the person requesting such issue has paid to the Company the amount of
any such tax, or has established, to the satisfaction of the Company, that such
tax has been paid.

     (S) 9.    Warrant Repurchase.  The holder of this Warrant shall have the
               ------------------                                        
right at its option, for up to fifteen (15)

                                      -24-
<PAGE>
 
business days following the first to occur of (i) the Company's payment in full
of the Notes for cash prior to their stated maturity or (ii) the maturity of the
Notes in accordance with their terms (including maturity due to acceleration
thereunder), to cause the Company to repurchase for cash this Warrant in an
amount equal to the holder of this Warrant's pro rata share (such pro rata share
to be determined based on the total number of shares of Common Stock underlying
any exercised or unexercised Warrant issued pursuant to the Warrant Agreement)
of an amount equal to the amount necessary to cause a 12.5% IRR to be achieved
by the holder of the Company's $10mm Note (assuming that the Warrant Repurchase
Price (as defined below) is received by such holder).

          If the holder hereof elects to have the Company repurchase this
Warrant in accordance with this (S) 9, the holder hereof shall provide notice to
the Company at the Company's address set forth in (S) 17 hereof within the time
period specified above.  Upon receipt of such request, the Company shall provide
an accounting of the amount to be paid for the repurchase of this Warrant (the
"WARRANT REPURCHASE PRICE") to the holder hereof within five (5) Business Days
of receipt of such notice (the "ACCOUNTING NOTICE").  Within five (5) Business
Days from the mailing of such Accounting Notice, the Company shall deliver in
immediately available funds to the holder hereof the Warrant Repurchase Price.
Upon receipt of the Warrant Repurchase Price, this Warrant shall no longer be
exercisable and shall be returned to the Company for cancellation.

     (S) 10.   Voting Rights.  This Warrant shall not entitle the holder hereof
               -------------                                                   
to voting rights with respect to the underlying Warrant Stock or to any rights
as a stockholder of the Company with respect to such underlying Warrant Stock
until this Warrant has been exercised in accordance with its terms.

     (S) 11.   Restrictions on Transferability.  The Warrants and the Warrant
               -------------------------------                               
Stock shall be transferable only (i) in accordance with the provisions of
Section 6 of the Warrant Agreement and (ii) upon compliance with the conditions
specified in this Warrant and in compliance with the provisions of the
Securities Act and applicable state securities laws in respect of the 

                                      -25-
<PAGE>
 
transfer of any Warrant or any Warrant Stock, and any holder of this Warrant
shall be bound by the provisions of (and entitled to the benefits of) (S) 3.

     (S) 12.   Limitation of Liability.  No provision hereof, in the absence of
               -----------------------                                         
affirmative action by the holder hereof to purchase shares of Common Stock, and
no mere enumeration herein of the rights or privileges of the holder hereof,
shall give rise to any liability of such holder for the purchase price or as a
stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

     (S) 13.   Loss, Destruction of Warrant Certificates.  Upon receipt of

        ---------------------------------                                  
agrees to purchase, for the consideration hereinafter set forth, and subject to
the terms and provisions herein contained, the following described properties,
rights and interests:

        (a) All right, title and interest of Seller in and to oil, gas and/or
    mineral leases described on EXHIBIT A hereto; and

    derived from, all presently existing and valid oil, gas and/or mineral

    existing and valid production sales contracts, operating agreements, and
    other agreements and contracts which relate to any of the properties
    described in subsections (a) and (b) above, to the extent and only to the
    extent such rights, titles and interests are attributable to the properties
    described in subsections (a) and (b) above; and

        (d) All rights, titles and interests of Seller in and to all materials,
    supplies, machinery, equipment, improvements and other personal property and
    fixtures (including, but not by way of limitation, all wells, wellhead
    equipment, pumping units, flowlines, tanks, buildings, saltwater disposal
    facilities, injection facilities, compression facilities, gathering systems,
    and other equipment) located on the properties described in subsections (a)
    and (b) above and used in connection with the exploration, development,
    operation or maintenance thereof, and in and to water rights, permits,
    licenses, rights of way, easements, and other rights of surface use used in
    connection with the exploration, development, operation or maintenance, of
    the properties described in subsections (a) and (b) above, in each case to
    the extent and only to the extent such rights, titles and interests are
    attributable to the properties described in subsections (a) and (b) above.

The properties, rights and interests specified in the foregoing subsections (a)
and (b), exclusive of the properties, rights and interests excluded below, are
herein sometimes collectively called the "OIL AND GAS PROPERTIES," and the

not include, and there is hereby expressly excepted and excluded therefrom and
reserved to Seller, all rights and choses in action, arising, occurring or
existing in favor of Seller prior to the Effective Date or arising out of the
operation of or production from the Oil and Gas Properties prior to the
Effective Date (including, but not limited to, any and all contract rights,
claims, receivables, revenues, recoupment rights, recovery rights, accounting
adjustments, escrow accounts, mispayments, erroneous payments or other claims of
any nature in favor of Seller and relating and accruing to any time period prior
to the Effective Date).

    2. PURCHASE PRICE.  The purchase price for the Properties shall be Fifty One
       --------------                                                           
Million Three Hundred Forty Two Thousand ($51,342,000) (such amount, unadjusted
by any adjustments provided for in this Agreement or agreed to by the parties,
being herein called the "BASE PURCHASE PRICE").  Such Base Purchase Price may be
adjusted as provided in this Agreement (the Base Purchase Price, as so adjusted,
and as the same may otherwise be adjusted by mutual agreement of the parties,
being herein called the "PURCHASE PRICE").  The Purchase Price shall be paid in
cash, by wire transfer, at the Closing as hereinafter provided.

    3. DEPOSIT.  Not later than the next business day following the execution of
       -------                                                                  
this Agreement, Buyer has paid to Seller an amount equal to ten percent (10%) of
the Base Purchase Price (such amount is being herein called the "DEPOSIT").  In
the event the transaction contemplated hereby is consummated in accordance with
the terms hereof, the Deposit shall be applied to the Purchase Price to be paid
by Buyer at the Closing.  In the event Seller defaults on its obligation to
close the transaction contemplated hereby in the absence of a default by Buyer,
or in the event the Agreement is terminated by Buyer or Seller under Sections
9(a), 9(b), 9(c), 9(d), 10(c), or 10(d), the Deposit shall be returned to Buyer.
If the transaction contemplated hereby otherwise fails to close on the Closing
Date, Seller shall retain the Deposit.  The Deposit shall not bear interest.
THE PARTIES HEREBY ACKNOWLEDGE THAT THE EXTENT OF DAMAGES TO SELLER OCCASIONED
BY THE FAILURE OF THIS TRANSACTION TO BE CONSUMMATED WOULD BE IMPOSSIBLE OR
EXTREMELY DIFFICULT TO ASCERTAIN AND THAT THE AMOUNT OF THE DEPOSIT IS A FAIR
AND REASONABLE ESTIMATE OF SUCH DAMAGES UNDER THE CIRCUMSTANCES AND DOES NOT
CONSTITUTE A PENALTY.

    6.  CERTAIN COVENANTS OF SELLER PENDING CLOSING.  Between the date of this
        -------------------------------------------                           
Agreement and the Closing Date:

        (a)  ACCESS BY BUYER.
             --------------- 

             (i) RECORDS.  Seller will give Buyer, or Buyer's authorized
                 -------                                                
        representatives, at Seller's office and at all reasonable times before
        the Closing Date, access to Seller's records pertaining to the ownership
        and/or operation of the Properties (including, 

                                       5
<PAGE>
 
        without limitation, title files, division order files, and production,
        severance and ad valorem tax records), for the purpose of conducting due
        diligence reviews contemplated by Section 7 below. Buyer may make copies
        of such records, at its expense, but shall, if Seller so requests,
        return all copies so made if the Closing does not occur; all costs of
        copying such items shall be borne by Buyer. Seller shall not be
        obligated to provide Buyer with access to any records or data which
        Seller considers to be proprietary or confidential to it or which Seller
        cannot provide to Buyer without, in its opinion, breaching, or risking a
        breach of, confidentiality agreements with other parties, or waiving, or
        risking waiving, legal privilege. BUYER RECOGNIZES AND AGREES THAT ALL
        MATERIALS MADE AVAILABLE TO IT IN CONNECTION WITH THE TRANSACTION
        CONTEMPLATED HEREBY, WHETHER MADE AVAILABLE PURSUANT TO THIS SECTION OR
        OTHERWISE, ARE MADE AVAILABLE TO IT AS AN ACCOMMODATION, AND WITHOUT
        REPRESENTATION OR WARRANTY OF ANY KIND AS TO THE ACCURACY AND
        COMPLETENESS OF SUCH MATERIALS. NO WARRANTY OF ANY KIND IS MADE BY
        SELLER AS TO THE INFORMATION SUPPLIED TO BUYER OR WITH RESPECT TO
        PROPERTIES TO WHICH THE INFORMATION RELATES, AND BUYER EXPRESSLY AGREES
        THAT ANY CONCLUSIONS DRAWN THEREFROM SHALL BE THE RESULT OF ITS OWN
        INDEPENDENT REVIEW AND JUDGMENT.

           (ii)   PHYSICAL INSPECTION.  Seller shall give Buyer, or Buyer's
                  -------------------                                      
        authorized representatives, at all reasonable times before the Closing
        Date and upon adequate notice to Seller, physical access to the Oil and
        Gas Properties which Seller operates, for the purpose of inspecting
        same. Buyer recognizes that some or all of the Properties may be
        operated by parties other than Seller and that Seller's ability to
        obtain access to such properties, and the manner and extent of such
        access, is subject to such third parties. Buyer agrees to comply fully
        with the rules, regulations and instructions issued by Seller (and,
        where Properties are operated by other parties, such other parties)
        regarding the actions of Buyer while upon, entering or leaving the
        Properties.

           (iii)  EXCULPATION AND INDEMNIFICATION.  If Buyer exercises rights of
                  -------------------------------                               
        access under this Section or otherwise, or conducts examinations or
        inspections under this Section or otherwise, then (a) such access,
        examination and inspection shall be at Buyer's sole risk, cost and
        expense and Buyer waives and releases all claims against Seller (its
        affiliates and its and their respective directors, officers, employees,
        attorneys, contractors and agents) arising in any way therefrom or in
        any way connected therewith or arising in connection with the conduct of
        its directors, officers, employees, attorneys, contractors and agents in
        connection therewith and (b) Buyer shall indemnify, defend and hold
        harmless Seller (and its affiliates and its and their respective
        officers, directors, employees, attorneys, contractors and agents) from
        any and all claims, actions, causes of action liabilities, damages,
        losses, costs or expenses (including, without limitation, court costs
        and attorneys

                                       6
<PAGE>
 
        fees), or liens or encumbrances for labor or materials, arising out of
        or in any way connected with such matters. THE FOREGOING RELEASE AND
        INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH CLAIMS, ACTIONS, CAUSES
        OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS OR EXPENSES ARISE OUT OF
        (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE NEGLIGENCE, CONCURRENT
        NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT INCLUDING
        GROSS NEGLIGENCE) OF SELLER OR ANY OTHER INDEMNIFIED PARTY, OR (ii)
        STRICT LIABILITY.

        (b)  INTERIM OPERATION.  Seller will continue the operation of the
             -----------------                                            
   Properties in the ordinary course of its business (or, where Seller is not
   the operator of a Property, will continue its actions as a non-operator in
   the ordinary course of its business), and will not sell or otherwise dispose
   of any portion of the Oil and Gas Properties; provided that Seller shall not
   be obligated to renew or extend expiring leases after the Effective Date
   unless mutually agreed at Buyer's expense.  Seller may make sales or other
   dispositions of oil, gas and other minerals in the ordinary course of
   business after production, and may make sales or other dispositions of
   portions of the Properties other than Oil and Gas Properties so long as (i)
   such sales or other dispositions are in the ordinary course of business and
   (ii) in the case of equipment, other personal property or fixtures described
   in Section 1(d) above, such equipment, other personal property or fixtures
   has become obsolete or is replaced by an item or items of at least equal
   suitability.  Except for those disclosed on SCHEDULE 6(b) attached hereto,
   Seller will not, without Buyer's consent, propose the drilling of any
   additional wells, or propose the deepening, plugging back or reworking of any
   existing wells, or propose the conducting of any other operations which
   require consent under the applicable operating agreement.  Except for those
   disclosed on SCHEDULE 6(b) attached hereto (with respect to which Seller may
   take the action or actions disclosed in connection therewith on such SCHEDULE
   6(b)), Seller will advise Buyer of any such proposals made by other parties,
   and will consult with Buyer concerning such proposals, but any decisions with
   respect to proposals shall be made by Seller in its own discretion, so long
   as the decisions are made in the ordinary course of business; provided that,
   if the period for responding to such a proposal extends beyond the Closing
   Date, Seller will not respond to such proposal unless the Closing does not
   occur prior to the next to last day allowed to respond (in which case Seller
   may respond).  Without expanding any obligations which Seller may have to
   Buyer, it is expressly agreed that Seller shall never have any liability to
   Buyer with respect to operation of a Property greater than that which it
   might have as the operator to a non-operator under the applicable operating
   agreement (or, in the absence of such an agreement, under the AAPL 610 (1989
   Revision) form Operating Agreement), IT BEING RECOGNIZED THAT, UNDER SUCH
   AGREEMENTS AND SUCH FORM, THE OPERATOR IS NOT RESPONSIBLE FOR ITS OWN
   NEGLIGENCE, AND HAS NO RESPONSIBILITY OTHER THAN FOR GROSS NEGLIGENCE OR
   WILFUL MISCONDUCT.

                                       7
<PAGE>
 
        (c)  PREFERENTIAL RIGHTS.  Seller will use its best efforts, consistent
             -------------------                                               
    with industry practices in transactions of this type, to identify, with
    respect to all material Oil and Gas Properties, (i) all preferential rights
    to purchase ("PREFERENTIAL RIGHTS") which would be applicable to the
    transactions contemplated hereby and (ii) the names and addresses of parties
    holding such rights; in attempting to identify such Preferential Rights, and
    the names and addresses of such parties holding the same, Seller shall in no
    event be obligated to go beyond its own records. Seller will request, from
    the parties so identified (and in accordance with the documents creating
    such rights), execution of waivers of Preferential Rights so identified.
    Seller shall have no obligation other than to so attempt to identify such
    Preferential Rights and to so request such execution of waivers of
    Preferential Rights (including, without limitation, Seller shall have no
    obligation to assure that such waivers of Preferential Rights are obtained).
    If a party from whom a waiver of a Preferential Right is requested refuses
    to give such waiver, Seller will tender to such party the required interest
    in the Property (at a price equal to the amount specified in EXHIBIT B
    hereto for such Property, reduced appropriately, as determined by mutual
    agreement of Buyer and Seller, if less than the entire Property must be
    tendered), and to the extent that such Preferential Right is exercised by
    such party, and such interest in such Property is actually sold to such
    party so exercising such right, such interest in such Property will be
    excluded from the transaction contemplated hereby and the Purchase Price
    will be adjusted downward by the amount paid to Seller by the party
    exercising such right.

    7.  DUE DILIGENCE REVIEWS.
        --------------------- 

        (a)  REVIEW BY BUYER.  Buyer may conduct, at its sole cost, such title
             ---------------                                                  
    examination or investigation, and other examinations and investigations, as
    it may in its sole discretion choose to conduct with respect to the
    Properties in order to determine whether Defects (as below defined) exist.
    Should, as a result of such examinations and investigations, or otherwise,
    one or more matters come to Buyer's attention which would constitute a
    Defect (as below defined), and should there be one or more of such Defects
    which Buyer is unwilling to waive and close the transaction contemplated
    hereby notwithstanding the fact that such Defects exist, Buyer shall notify
    Seller in writing of such Defects as soon as the same are identified by
    Buyer, but in no event later than August 28, 1997 (such Defects of which
    Buyer so provides notice are herein called "ASSERTED DEFECTS"). Such
    notification shall include, for each Asserted Defect, (i) a description of
    the Asserted Defect and the wells and/or units listed on Exhibit B to which
    it relates and all supporting documentation reasonably necessary to fully
    describe the basis for the Defect, (ii) for each applicable well or unit,
    the size of any variance from "Revenue Interest" or "Working Interest" which
    does or could result from such Asserted Defect and (iii) the amount by which
    Buyer would propose to adjust the Purchase Price, based on the amounts
    attributable to the affected Properties as shown on Exhibit B. All Defects
    with respect to which Buyer fails to so give Seller notice will be deemed
    waived for all purposes. All access to Sellers records and the Properties in
    connection with such due diligence shall be subject and pursuant to Section
    6(a) (including, without limitation, the exculpation and indemnification
    provisions contained in Section 6(a)(iii)).

                                       8
<PAGE>
 
        (b)  NATURE OF DEFECTS.  The term "DEFECT" as used in this Section shall
             -----------------                                                  
   mean the following:

             (i)   NRI OR WI VARIANCES.  Seller's ownership of the Properties is
                   -------------------                                          
        such that, with respect to a well or unit listed on EXHIBIT B hereto, it
        clearly (A) entitles Seller to receive a decimal share of the oil, gas
        and other hydrocarbons produced from such unit, or from currently
        producing completions in such well, which is less than the decimal share
        set forth on EXHIBIT B in connection with such well or unit as the
        "Revenue Interest" or (B) causes Seller to be obligated to bear a
        decimal share of the cost of operation of such well (as to such
        completions) or unit

                                       9
<PAGE>
 
        greater than the decimal share set forth on EXHIBIT B in connection with
        such well or unit as the "Working Interest" (without at least a
        proportionate increase in the share of production to which Seller is
        entitled to receive).

             (ii)  NET ACRE SHORTFALLS.  Seller's ownership of the Properties is
                   -------------------                                          
        such that it clearly entitles Seller to fewer than 23,511 total net
        undeveloped acres (defined below) in the Certain Townships (below
        defined). "NET UNDEVELOPED ACRES" shall be computed separately for each
        lease identified on Exhibit A and shall mean, for each such lease, (a)
        the number of acres covered by such lease which are located in the
        Certain Townships and not included in a spacing unit for a producing
        well, multiplied by (b) the interest in oil and gas covered by such
        lease in such lands, multiplied by (c) Seller's undivided interest in
        such lease insofar as it covers such lands (provided that if items (b)
        and/or (c) vary as to different areas, a separate calculation shall be
        done for each such area). "TOTAL NET UNDEVELOPED ACRES" shall mean the
        total of the amounts computed under the preceding sentence for all
        leases described on Exhibit A covering lands in the Certain Townships.
        "CERTAIN TOWNSHIPS" means T8S, R15E; T9S, R15E; T8S, R16E; T9S, R16E;
        T8S, R17E; T9S, R17E; T8S, R18E; and T9S, R18E, Uintah and Duschene
        Counties, Utah.

             (iii) LIENS.  Seller's ownership of an Oil and Gas Property is
                   -----                                                   
        subject to a lien other than (A) a lien for taxes which are not yet
        delinquent or (B) a mechanic's or materialmen's lien (or other similar
        lien), or a lien under an operating agreement or similar agreement, to
        the extent the same relates to expenses incurred which are not yet
        delinquent or (C) liens which will be released at or before Closing.

             (iv)  PREFERENTIAL RIGHTS.  Seller's ownership of an Oil and Gas
                   -------------------                                       
        Property is subject to a Preferential Right, unless a waiver of such
        Preferential Right has been obtained with respect to the transaction
        contemplated hereby or an appropriate tender of the applicable interest
        has been made to all parties holding such right and, with respect to
        each such party, either (A) the period of time required for such party
        to exercise such right has expired without such party exercising such
        right, or (B) such right has been exercised and the affected portion of
        the Properties has been excluded from the transactions contemplated
        hereby (and the Purchase Price adjusted downward) as provided in Section
        6(c).

             (v)   IMPERFECTIONS IN TITLE.  Seller's ownership of an Oil and Gas
                   ----------------------                                       
        Property is subject to an imperfection in title which is not such as
        would normally be waived by persons engaged in the oil and gas business
        when purchasing properties of a similar size, nature, location and
        value.

             (vi)  ENVIRONMENTAL MATTERS.  Except as disclosed on SCHEDULE
                   ---------------------                                  
        7(B)(VI), an environmental condition exists as to an Oil and Gas
        Property which is required to be remediated by applicable environmental
        laws (below defined) in any material respect ("applicable environmental
        laws" shall mean all federal, state or local laws, rules, orders or
        regulations pertaining to health or the environment, including those
        relating to waste materials and/or hazardous substances).

Notwithstanding anything in the foregoing which may appear to the contrary, a
gas imbalance (e.g., a situation where Seller and its predecessors in title to
the Properties have taken more or less gas from a well or unit than ownership of
the Properties would

                                       10
<PAGE>
 
entitle them to receive) shall not constitute a Defect; provided that an
adjustment at Closing may be made for the same pursuant to Section 12(e).

        (c)  SELLER'S RESPONSE.  In the event that Buyer notifies Seller of
             -----------------                                             
    Asserted Defects:

             (i)   CURE. Seller may (but shall have no obligation to) attempt to
                   ----
        cure, prior to Closing, one or more Asserted Defects.

             (ii)  POSTPONE CLOSING. Whether or not Seller has then begun to, or
                   ----------------
        ever begins to, cure one or more Asserted Defects (and whether or not
        Seller has elected options (iii) or (iv) below with respect to one or
        more Asserted Defects), Seller may postpone the Closing by designating a
        new Closing Date not later than October 10, 1997. Notwithstanding any
        such election to postpone Closing, Seller shall still have no obligation
        to cure Asserted Defects.

             (iii) INDEMNIFICATION.  At any time, and from time to time, prior 
                   ---------------      
        to Closing, and regardless of whether or not Seller has then elected any
        other option or options under this Section as to such Asserted Defect or
        any other Asserted Defect (including without limitation regardless of
        whether the procedure under Section 8 is ongoing as to such Asserted
        Defect), Seller may (but shall have no obligation to) elect, with
        respect to any Asserted Defect, covered by Sections 7(b)(ii) through
        (v), to indemnify and hold Buyer harmless from and against any actual
        damages or loss (but specifically excluding consequential, special or
        similar damages) Buyer may suffer as a result of a third party claim
        based on such Asserted Defect. If and when such election is made as to
        an Asserted Defect, such Asserted Defect will be treated under this
        Agreement as if cured.

             (iv)  ADJUSTMENT. Notwithstanding any other election made under 
                   ----------
        this Section (without limitation, it being expressly recognized that
        Seller may attempt to cure Asserted Defects while acting under this
        election), Seller may elect to have one or more Asserted Defects handled
        under Section 8 below.

    8.  CERTAIN PRICE ADJUSTMENTS.
        ------------------------- 

        (a)  PROCEDURES.  In the event that, as a part of the due diligence
             ----------                                                    
    reviews provided for in Section 7 above, Asserted Defects are presented to
    Seller and Seller is unable (or unwilling) to cure such Asserted Defects
    prior to Closing, or in the event that Buyer has elected (pursuant to
    Section 15) to treat an Oil and Gas Property affected by a casualty loss as
    if it was an Oil and Gas Property affected by an Asserted Defect, then:

             (i)   AGREE UPON ADJUSTMENT. Buyer and Seller shall, with respect 
                   ---------------------
        to each Property affected by such matters, attempt to agree upon an
        appropriate downward adjustment of the Purchase Price to account for
        such matters; and

                                       11
<PAGE>
 
             (ii)  EXCLUDE PROPERTY. With respect to each Property as to which
                   ----------------
        Buyer and Seller are unable to agree upon appropriate adjustment with
        respect to all such matters affecting such Property, such Property will
        be excluded from the transaction contemplated hereby, and the Purchase
        Price will be reduced by (a) the amount attributed on EXHIBIT B to the
        wells located on such Property plus the amount attributed on EXHIBIT B
        to the units in which such Property participates (but in the case of
        such units, limited to the portion of such amount which is proportionate
        to the portion of Seller's interest in such units, respectively, which
        is attributable to such Property), plus (b) $400 per acre for each net
        undeveloped acre included on such Property.

If the above procedure is applied to an Asserted Defect (or if Buyer identified
a Defect but elected not to assert it as an Asserted Defect) then, regardless of
whether an adjustment in the Purchase Price results therefrom, such Defect may
not be the subject of any other claims by Buyer against Seller (including,
without limitation,the same may not be asserted as the basis for any indemnity
under Section 13 hereof).

        (b)  CERTAIN ADJUSTMENTS.  In the event that Buyer raises as an Asserted
             -------------------                                                
    Defect one of the following types of Defects, the Purchase Price shall be
    adjusted as set forth below in connection with such Defect:

             (i)   NRI VARIANCE/PROPORTIONATE PRICE REDUCTIONS. If the Asserted
                   -------------------------------------------
        Defect is a Defect described in clause (A) of Section 7(b)(i): a
        downward adjustment equal to the amount determined by multiplying the
        amount set forth for such well or unit on EXHIBIT B by a fraction (A)
        the numerator of which is an amount equal to the reduction (from the
        "Revenue Interest" shown on EXHIBIT B for such well or unit) which has
        clearly been determined to exist in the decimal share to which Seller is
        entitled to as a result of its ownership interest in such well or unit
        and (B) the denominator of which is the "Revenue Interest" shown for
        such well or unit on EXHIBIT B.

             (ii)  NET ACRES SHORTFALL PROPORTIONATE PRICE REDUCTION. If the
                   -------------------------------------------------
        Asserted Defect is a Defect described in Section 7(b)(ii): a downward
        adjustment equal to an amount determined by multiplying $400 per acre by
        the net acre shortfall which has clearly been determined to exist.

If such an adjustment is made, such adjustment will be deemed an adjustment
agreed to under Section 8(a)(i) above.

        (c)  POSSIBLE UPWARD ADJUSTMENTS.  Should Seller determine (or should
             ---------------------------                                     
    Buyer, in the course of its due diligence reviews contemplated by Section 7
    above, determine) that the ownership of the Properties by Seller entitles
    Seller to a decimal share of the production from a well or unit listed on
    EXHIBIT B greater than the decimal share shown as the "Revenue Interest" for
    such well or unit on such EXHIBIT

    B, then Seller may propose an upward adjustment to the Purchase Price to
    account for such fact, in which case such adjustment shall be handled in the
    same manner as provided in Section 8(a) above with respect to adjustments
    for Asserted Defects. The party making such determination shall notify the
    other party no later than the Closing Date.

        (d)  LIMITATIONS ON ADJUSTMENTS.  If the Purchase Price reductions (or
             --------------------------                                       
    increases) which result from the above provided for procedure do not exceed
    in the aggregate two percent (2%) of the Base Purchase Price, then no
    adjustment of the Purchase Price shall occur, and none of the Oil and Gas
    Properties which would be excluded by such procedure shall be excluded. If
    the Purchase Price reductions (or increases) which result from the above
    provided for procedure exceed in the aggregate two percent (2%) of the Base
    Purchase Price, the Purchase Price shall be adjusted by the amount by which
    such reduction (or increase) exceeds two percent (2%) of the Base Purchase
    Price.

    9.  CONDITIONS PRECEDENT TO THE OBLIGATIONS OF BUYER.  The obligations of
        ------------------------------------------------                     
Buyer under this Agreement are subject to each of the following conditions being
met:

        (a)  REPRESENTATIONS TRUE AND CORRECT.  Each and every representation of
             --------------------------------                                   
    Seller under this Agreement shall be true and accurate in all material
    respects as of the date when made and shall be deemed to have been made
    again at and as of the time of Closing and shall at and as of such time of
    Closing be true and accurate in all material respects except as to changes
    specifically contemplated by this Agreement or consented to by Buyer.

        (b)  COMPLIANCE WITH COVENANTS AND AGREEMENTS.  Seller shall have
             ----------------------------------------                    
    performed and complied in all material respects with (or compliance
    therewith shall have been waived by Buyer) each and every covenant and
    agreement required by this Agreement to be performed or complied with by
    Seller prior to or at the Closing.

        (c)  PRICE ADJUSTMENT LIMITATIONS.  The aggregate downward adjustment 
             ----------------------------       
    (if any) of the Purchase Price which results from the procedures set forth
    in Sections 6(c), 8 and 15 does not exceed fifteen (15%) percent of the Base
    Purchase Price.

        (d)  LITIGATION.  No suit, action or other proceedings shall, on the 
             ----------            
    date of Closing, be pending or threatened before any court or governmental
    agency seeking to restrain, prohibit, or obtain material damages or other
    material relief in connection with the consummation of the transactions
    contemplated by this Agreement, other than litigation instituted by Buyer or
    any affiliate of Buyer.

If any such condition on the obligations of Buyer under this Agreement is not
met as of the Closing Date, and Buyer is not in breach of its obligations
hereunder, this Agreement may, at the option of Buyer, be terminated.  In the
event such a termination by Buyer occurs, the parties shall have no further
obligations to one another hereunder (other than 

                                       13
<PAGE>
 
the obligations under Sections 6(a)(iii) and 14 hereof, all of which will
survive such termination), and the Deposit will be refunded to Buyer. With
respect to any condition set forth above (other than condition (c) or (d)) which
is not met (and which is asserted by Buyer as a failure of one of its conditions
of Closing), and for which the reasons why such condition is not met relate to
some, but less than all, of the Properties, Seller may require that such failure
of such condition to be met be treated as an uncured Asserted Defect and handled
in accordance with the process set forth in Section 8 above, and, if Seller so
requires such handling, such condition will be considered met for the purposes
of this Section.

    10. CONDITIONS PRECEDENT TO THE OBLIGATIONS OF SELLER.  The obligations of
        -------------------------------------------------                     
Seller under this Agreement are subject to the each of the following conditions
being met:

        (a)  REPRESENTATIONS TRUE AND CORRECT.  Each and every representation of
             --------------------------------                                   
    Buyer under this Agreement shall be true and accurate in all material
    respects as of the date when made and shall be deemed to have been made
    again at and as of the time of Closing and shall at and as of such time of
    Closing be true and accurate in all material respects except as to changes
    specifically contemplated by this Agreement or consented to by Seller.

        (b)  COMPLIANCE WITH COVENANTS AND AGREEMENTS.  Buyer shall have
             ----------------------------------------

    therewith shall have been waived by Seller) each and every covenant and
    agreement required by this Agreement to be performed or complied with by
    Buyer prior to or at the Closing.

        (c)  PRICE ADJUSTMENT LIMITATIONS.  The aggregate downward adjustment 
             ----------------------------                 
    (if any) to the Base Purchase Price which results from the procedures set
    forth in Sections 8 and 15 does not exceed fifteen (15%) percent of the Base
    Purchase Price.

        (d)  LITIGATION.  No suit, action or other proceedings shall, on the 
             ----------            
    date of Closing, be pending or threatened before any court or governmental
    agency seeking to restrain, prohibit, or obtain material damages or other
    material relief in connection with the consummation of the transactions
    contemplated by this Agreement, other than litigation instituted by Seller
    or any affiliate of Seller.

If any such condition on the obligations of Seller under this Agreement is not
met as of the Closing Date, and Seller is not in breach of its obligations
hereunder, this Agreement may, at the option of Seller, be terminated.  In the
event such a termination by Seller occurs, the parties shall have no further
obligations to one another hereunder (other than the obligations under Sections
6(a)(iii) and 14 hereof, all of which will survive such termination), and the
Deposit will be refunded to Buyer or retained by Seller as provided in Section 3
hereof.

    11. CLOSING.

                                       14
<PAGE>
 
        (a)  ACTIONS AT CLOSING.  The closing (herein called the "CLOSING") of
             ------------------                                               
    the transaction contemplated hereby shall take place in the offices of
    Seller, at 5555 San Felipe, Suite 2100, Houston, Texas 77056, on September
    30, 1997, at 10:00 a.m., local time, or at such other date and time (i) as
    the Buyer and Seller may mutually agree upon or (ii) to which Seller may
    postpone the Closing pursuant to Section 7 hereof (such date and time, as
    changed pursuant to clauses (i) and (ii), being herein called the "CLOSING
    DATE"). At the Closing:

             (i)   DELIVERY OF CONVEYANCE.  Seller shall execute, acknowledge 
                   ----------------------          
        and deliver to Buyer a conveyance of the Properties (the "CONVEYANCE"),
        in the form attached hereto as ANNEX I (and with EXHIBIT A hereto being
        attached thereto as EXHIBIT A), effective as to runs of oil and
        deliveries of gas and for all other purposes as of 7 o'clock a.m., local
        time at the locations of the Properties, respectively, on April 1, 1997
        (herein called the "EFFECTIVE DATE").

             (ii)  FEDERAL AND STATE CONVEYANCE FORMS.  Seller shall execute 
                   ----------------------------------          
        (and, where required, acknowledge) and deliver to Buyer forms of
        conveyance or assignment as required by the applicable authorities for
        transfers of interests in state or federal leases included in the Oil
        and Gas Properties.

             (iii) LETTERS IN LIEU.  If Buyer so requests, Seller shall execute
                   ---------------                                             
        and deliver to Buyer letters in lieu of transfer orders (or similar
        documentation), in form acceptable to both parties.

             (iv)  TURN OVER POSSESSION.  Seller shall, to the extent Seller 
                   --------------------          
        can do so, turn over possession of the Properties.

             (v)   PAYMENT TO SELLER.  Buyer shall deliver to the Seller, by 
                   -----------------         
        wire transfer of immediately available funds to an account designated by
        Seller in a bank located in the United States, an amount equal to (A)
        the Purchase Price, less or plus (as the case may be) (B) any
        adjustments under this Agreement which are to be made at Closing, less
        (C) the Deposit, plus (D) interest at the Agreed Rate (below defined) on
        an amount equal to (I) the Base Purchase Price less (II) the Deposit,
        from the Effective Date to Closing. The "AGREED RATE" shall mean a rate
        per annum equal the lesser of (i) the Prime Rate in effect from time to
        time, as published in The Wall Street Journal under the caption "Money
                              ----------------------     
        "Money Rates" (provided, that in the event The Wall Street Journal 
                                                   -----------------------
        shall publish a split Prime Rate, the higher of such Prime Rates shall
        apply) and (ii) the maximum interest rate permitted by applicable law.

             (vi)  SUCCESSION BY BUYER.  Buyer shall, (A) furnish to Seller such
                   -------------------                                          
        evidence (including, without limitation, evidence of satisfaction of all
        applicable bonding requirements) as Seller may require that Buyer is
        qualified with the applicable authorities to succeed Seller as the owner
        and, where applicable, operator of the Properties, (B) with respect to
        properties operated by Seller

                                       15
<PAGE>
 
        where Buyer is to succeed Seller as operator, execute and deliver to
        Seller appropriate evidence reflecting change of operator as required by
        applicable authorities, and (C) execute and deliver to Seller such forms
        as Seller may reasonably request for filing with the applicable
        authorities to reflect Buyer's assumption of plugging and abandonment
        liabilities with respect to the wells located on the Properties or on
        units in which the Properties participate.

             (vii) NON FOREIGN STATUS AFFIDAVIT.  If Buyer so requests, each 
                   ----------------------------            
        party Seller will execute and deliver to Buyer an affidavit or other
        certification (as permitted by such code) that such party is not a
        "foreign person" within the meaning of Section 1445 (or similar
        provisions) of the Internal Revenue Code of 1986 as amended (i.e., such
        party is not a non-resident alien, foreign corporation, foreign
        partnership, foreign trust or foreign estate as those terms are defined
        in such code and regulations promulgated thereunder).

        (b)  POST CLOSING ACTIONS.
             -------------------- 

             (i)   NOTIFICATIONS BY BUYER.  Immediately after the Closing, 
                   ----------------------               
        Buyer shall notify all applicable operators, non-operators, oil and gas
        purchasers, and government agencies that it has purchased the
        Properties.

             (ii)  TRANSFER OF FILES.  Seller will use its best efforts to 
                   -----------------                       
        deliver to Buyer, at Buyer's expense and within 45 days after Closing,
        all of Seller's lease files, abstracts and title opinions, division
        order files, production records, well files, accounting records (but not
        including general financial accounting or tax accounting records), and
        other similar files and records which directly relate to the Properties,
        other than those which Seller considers to be proprietary or
        confidential to it or which Seller cannot provide to Buyer without, in
        its opinion, breaching, or risking a breach of, confidentiality
        agreements with other parties, or waiving, or risking waiving, legal
        privilege. Seller may, at its election, make and retain copies of any or
        all such files. Buyer shall preserve all files so delivered by Seller of
        a period of ten years following Closing and will allow Seller access
        (including, without limitation, the right to make copies at Seller's
        expense) to such files at all reasonable times; specifically in this
        connection (but not in limitation of the foregoing) Buyer recognizes
        that Seller has received certain information requests from the United
        States regarding payment of royalties on federal leases which, in order
        to respond to, Seller will need access to such files.

             (iii) OPERATIONAL TRANSITION.
                   ---------------------- 

                   (A)  OPERATIONS.  For a reasonable period of time after 
                        ----------                    
             Closing, Buyer and Seller shall cooperate with respect to
             transition activities as to Properties where Buyer succeeds Seller
             as operator. IT IS RECOGNIZED THAT THERE IS NO ASSURANCE GIVEN BY

                                       16
<PAGE>
 
             SELLER THAT BUYER SHALL SUCCEED SELLER AS OPERATOR OF ANY PROPERTY
             WHERE OTHER PARTIES OWN INTERESTS IN THE WELLS LOCATED THEREON.  To
             the extent Seller remains an operator after Closing (which it shall
             have no obligation to do), it shall serve as operator under the
             applicable operating agreement in the manner provided by such
             agreement (or, in the absence of such an agreement, in the manner
             contemplated by the AAPL610 (1989) form Operating Agreement).  For
             each Property for which Seller continues to so operate after
             Closing, Seller shall be entitled to receive, for each calendar
             month for which it operates such Property for any part of such
             month, (i) if such Property is covered by an operating agreement,
             the overhead charge provided for in such agreement, and (ii) if
             such Property is not covered by an operating agreement, an overhead
             charge (to be paid by Buyer to Seller) equal to the per month
             overhead charge provided for under Section 12(a) for wells not
             covered by operating agreements.  When Buyer takes over operation
             of a Property, it will reimburse Seller for (i) all outstanding
             joint interest billing receivables which relate to billings
             rendered since the Effective Date, and (ii) all unbilled joint
             interest expenses (including overhead charges), and the collection
             of the same will thereafter be the responsibility of, and for the
             account of, Buyer. Except to the extent Seller continues to so
             operate one or more Properties after Closing (which, as provided
             above, it has no obligation to do), or continues to provide
             disbursement services as provided for in subsection (B) below, any
             additional services provided by Seller to Buyer shall be at
             Seller's sole discretion, and, to the extent Seller elects to
             provide any such additional services, the nature, manner of
             performance and compensation to Seller for such services shall be
             the subject of a separate agreement between Seller and Buyer.

                   (B)  CERTAIN DISBURSEMENTS.  With respect to each Oil and Gas
                        ---------------------                                   
             Property with respect to which Seller is disbursing proceeds of
             production attributable to other parties entitled thereto, (i)
             Seller shall continue to collect proceeds of production up to the
             end of the month in which Closing occurs (or, if Buyer is, despite
             its best efforts, unable to commence making disbursements as to
             some Properties at such time, such later date (but not to exceed
             the end of the month falling 3 months after Closing) requested by
             Buyer as to such Properties), and shall be responsible for making
             disbursements, in accordance with its normal procedures (and at
             normal times), of such proceeds of production so collected to the
             parties entitled to same, with any proceeds of production
             thereafter collected by Seller to be promptly forwarded to Buyer
             (who shall thereafter account for same to the parties entitled
             thereto) and (ii) Seller shall, as promptly as possible after
             Closing, deliver to Buyer (A) a copy of its "pay list" for 

                                       17
<PAGE>
 
        each such Property and (B) a list of all parties for whom it is holding
        in suspense proceeds of production. It is understood and agreed that
        Seller does not represent or warrant to Buyer the accuracy of the "pay
        lists" and other data so delivered. Upon Closing, Buyer shall become
        responsible for all disbursements of proceeds of production (including,
        without limitation, those disbursements made by Seller on Buyer's
        behalf) and such disbursement activities shall be included in the
        matters which Buyer assumes, and indemnifies Seller with respect to,
        under Section 13 below. With respect to each well for which Seller so
        provides such disbursement services after Closing, Seller shall be paid
        by Buyer an amount equal to $200 for each month for which it provides
        such services for such well (beginning with the month in which Closing
        occurs).

             (C)   RESPONSIBILITIES AND INDEMNIFICATION.  To the extent Seller
                   ------------------------------------                       
        so operates any Property after Closing, or so provides disbursement
        services (or agrees to provide additional services), its obligations to
        Buyer with respect to such services shall be no greater than those which
        it would have as an operator to a non-operator under the applicable
        operating agreement (or, in the absence of an operating agreement, under
        the AAPL610 (1989 Revision) form Operating Agreement), IT BEING
        RECOGNIZED THAT, UNDER SUCH AGREEMENTS AND SUCH FORM, THE OPERATOR IS
        NOT RESPONSIBLE FOR ITS OWN NEGLIGENCE, AND HAS NO RESPONSIBILITY OTHER
        THAN FOR GROSS NEGLIGENCE OR WILFUL MISCONDUCT. SELLER'S ACTIONS IN
        PROVIDING SUCH SERVICES WILL BE COVERED BY THE INDEMNIFICATIONS PROVIDED
        BY BUYER UNDER SECTION 13 BELOW.

    12. CERTAIN ACCOUNTING ADJUSTMENTS.
        ------------------------------ 

        (a)  ADJUSTMENTS FOR REVENUES AND EXPENSES.  Appropriate adjustments
             -------------------------------------                          
    shall be made between Buyer and Seller so that (i) Buyer will bear all
    expenses which are incurred in the operation of the Properties after the
    Effective Date, including, without limitation, all drilling costs, all
    capital expenditures, all overhead charges under applicable operating
    agreements (regardless of whether such operating agreements are with third
    parties or related entities and regardless of whether Seller is the operator
    or a non-operator), all other overhead charges actually charged by third
    parties, and, where Seller is the operator of a well and there is no
    operating agreement, overhead at the rate of $550 per well per month
    (prorated for any period less than one month) for each month or part thereof
    between the Effective Date and Closing, and Buyer will receive all proceeds
    (net of applicable production, severance, and similar taxes) from sales of
    oil, gas and/or other minerals which are produced from (or attributable to)
    the Properties and which are produced after the Effective Date, and (ii)
    Seller

                                       18
<PAGE>
 
    will bear all expenses which are incurred in the operation of the Properties
    before the Effective Date and Seller will receive all proceeds (net of
    applicable production, severance, and similar taxes) from the sale of oil,
    gas and/or other minerals which were produced from (or attributable to) the
    Properties and which were produced before the Effective Date. It is agreed
    that, in making such adjustments: (i) oil which was produced from the Oil
    and Gas Properties and which was, on the Effective Date, stored in tanks
    located on the Oil and Gas Properties (or located elsewhere but used by
    Seller to store oil produced from, or attributable to, the Oil and Gas
    Properties prior to delivery to oil purchasers) and above pipeline
    connections shall be deemed to have been produced before the Effective Date,
    (ii) ad valorem and similar taxes assessed for periods prior to the
    Effective Date shall be borne by Seller and ad valorem taxes assessed for
    periods on or after the Effective Date shall be borne by Buyer (ad valorem
    and similar taxes shall be considered assessed for the period for which they
    are stated to be assessed, even if the same are based on production or other
    activities occurring in prior periods), (iii) ad valorem and similar taxes
    assessed with respect to a period which the Effective Date splits shall be
    prorated based on the number of days in such period which fall on each side
    of the Effective Date (with the day on which the Effective Date falls being
    counted in the period after the Effective Date), (iv) prepaid expenses
    attributed to periods after the Effective Date, but paid prior to the
    Effective Date, shall be treated as expenses for the period after the
    Effective Date, (v) the provisions of Section 18(c) shall be given effect as
    if the same had taken effect on the Effective Date, (vi) casualty losses
    shall be handled in accordance with Section 15, and (vii) no consideration
    shall be given to the local, state or federal income tax liabilities of any
    party.

        (b)  INITIAL ADJUSTMENT AT CLOSING.  At least 5 days before the Closing
             -----------------------------                                     
    Date, Seller shall provide to Buyer a statement showing its computations of
    the amount of the adjustments provided for in subsection (a) above based on
    amounts which prior to such time have actually been paid or received by
    Seller. Such statement shall also reflect any other adjustments provided for
    under this Agreement. Buyer and Seller shall attempt to agree upon such
    adjustments prior to Closing, provided that if agreement is not reached,
    Seller's computation shall be used at Closing, subject to further adjustment
    under subsections (c) and (d) below. If the amount of adjustments so
    determined which would result in a credit to Buyer exceed the amount of
    adjustments so determined which would result in a credit to Seller, Buyer
    shall, as provided in Section 11 above, receive a credit at Closing for the
    amount of such excess, and, if the converse is true, then, as provided in
    Section 11 above, the amount to be paid by Buyer to Seller at Closing shall
    be increased by the amount of such excess.

        (c)  ADJUSTMENT POST CLOSING.  On or before 120 days after Closing, 
             -----------------------                    
    Buyer and Seller shall review any additional information which may then be
    available pertaining to the adjustments provided for in subsection (a)
    above, shall determine if any additional adjustments should be made beyond
    those made at Closing (whether the same be made to account for expenses or
    revenues not considered in making the

                                       19
<PAGE>
 
    adjustments made at Closing, or to correct errors made in the adjustments
    made at Closing), and shall make any such adjustments by appropriate
    payments from Seller to Buyer or from Buyer to Seller.

        (d)  ADDITIONAL ADJUSTMENTS.  Should any additional items which would be
             ----------------------                                             
    the subject of adjustments provided for in subsection (a) above come to the
    attention of Buyer or Seller after such adjustments under subsection (c) are
    concluded, but prior to the end of two years following Closing, such
    adjustments shall be made by appropriate payments from Buyer to Seller or
    from Seller to Buyer. Except for any of such adjustments under the preceding
    sentence, no further adjustments shall be made under this Section 12, and
    should any expenses (or revenues) with regard to the Properties be charged
    to (or received by) Seller or Buyer after two years following Closing, the
    same shall be borne by (or in the case of revenues received by) Buyer,
    regardless of the periods to which the same relate, unless the same are
    revenues related to claims identified by Seller before the end of such two
    year period (and of which Seller gives Buyer notice before the end of such
    two year period), which revenues shall belong to Seller.

        (e)  IMBALANCE ADJUSTMENTS.  At Closing, Buyer and Seller shall, based
             ---------------------                                            
    upon data available at that time, determine (i) the total amount of
    "overproduction" of gas as of the Effective Date with respect to the wells
    and units listed on Exhibit B (e.g. volumes of gas, measured in mcf, taken
    from such wells and units by the Seller and its predecessors in title to the
    Properties in excess of those volumes, measured in mcf, which the ownership
    of the Properties would entitle them to receive) and (ii) total amount of
    "underproduction" of gas as of the Effective Date with respect to wells and
    units listed in Exhibit B (e.g. the amount by which the volumes of gas,
    measured in mcf, from such wells and units which the ownership of the
    Properties by Seller and its predecessors in title thereto entitle them to
    take exceeds the volumes, measured in mcf, taken from such wells by Seller
    and such predecessors). If the total amount of overproduction (as so
    determined) exceeds the total amount of underproduction (as so determined),
    then Buyer shall, as provided in Section 11 above, receive a credit against
    the Purchase Price equal to $1.50 times such excess. If the total amount of
    underproduction (as so determined) exceeds the total amount of
    overproduction (as so determined), then, as provided in Section 11 above,
    the amount to be paid by Buyer to Seller at Closing shall be increased by an
    amount equal to $1.50 times such excess.

        (f)  ADJUSTMENTS FOR JONAH UNIT ACCOUNTS RECEIVABLE.  Seller holds
             ----------------------------------------------               
    accounts receivable from certain other working interest owners in the Jonah
    Unit in the Monument Butte Field in Utah. Such accounts receivable will be
    assigned to Buyer at Closing, and the amount paid by Buyer to Seller at
    Closing shall be increased by an amount equal to the then outstanding
    balance of such accounts receivable plus any accrued interest thereon.

    13. ASSUMPTION AND INDEMNIFICATION.
        ------------------------------ 

                                       20

        (a)  BUYER'S INDEMNITY.  Buyer shall, on the date of Closing, agree 
             -----------------                       
    (and, upon the delivery to Buyer of the Conveyance, shall be deemed to have
    agreed), (i) to assume, and to timely pay and perform, all duties,
    obligations and liabilities relating to the acquisition, ownership and/or
    operation of the Properties on and after the Effective Date (including,
    without limitation, those arising under the contracts and agreements
    described in Section 1(c) above and the lease referred to in Section 1(e)
    above), and (ii) to indemnify and hold Seller, its affiliates, and its and
    their directors, officers, employees, attorneys, contractors and agents
    harmless from and against any and all claims, actions, causes of action,
    liabilities, damages, losses, costs or expenses (including, without
    limitation, court costs and attorneys' fees) of any kind or character
    arising out of or otherwise relating to the acquisition, ownership and/or
    operation of the Properties on and after the Effective Date. In connection
    with (but not in limitation of) the foregoing, it is specifically understood
    and agreed that such duties, obligations and liabilities arising out or
    otherwise relating to the acquisition, ownership and/or operation of the
    Properties on and after the Effective Date shall be deemed to include all
    matters arising out of the condition of the Properties on the Effective Date
    (including, without limitation, within such matters all obligations to
    properly plug and abandon, or replug and re-abandon, wells located on the
    Properties, to restore the surface of the Properties and to comply with, or
    to bring the Properties into compliance with, applicable environmental laws,
    rules, regulations and orders, including conducting any remediation
    activities which may be required on or otherwise in connection with
    activities on the Properties), regardless of whether such condition or the
    events giving rise to such condition arose or occurred before or after the
    Effective Date, and the assumptions and indemnifications by Buyer provided
    for in the first sentence of this section shall expressly cover and include
    such matters; provided however that it is expressly agreed that any waste,
    contaminants, substances, or materials that were shipped, transferred,
    removed, or disposed of off the Properties prior to Closing ("PRE-CLOSING
    SHIPPED MATERIALS") are the sole responsibility of Seller.

        (b)  SELLER'S INDEMNITY. Except for matters covered by Buyer's indemnity
             ------------------                                                 
    under Section 13(a) above, Seller shall, on the date of Closing, agree (and,
    upon the delivery to Buyer of the Conveyance shall be deemed to have agreed)
    to indemnify and hold Buyer, its affiliates, and its and their directors,
    officers, employees, attorneys, contractors and agents harmless from and
    against any and all third party (not affiliated with Buyer) claims, actions,
    causes of action, liabilities, damages,losses, costs or expenses (including,
    without limitation, court costs and attorneys' fees) of any kind or
    character arising out of or otherwise relating to the ownership and/or
    operation of the Properties prior to the Effective Date; provided that it is
    expressly understood that Seller's indemnity includes claims related to Pre-
    closing Shipped Materials.

        (c)  CERTAIN PROVISIONS APPLICABLE TO INDEMNIFICATION.  THE FOREGOING
             ------------------------------------------------                
    ASSUMPTIONS AND INDEMNIFICATIONS SHALL APPLY WHETHER OR NOT SUCH DUTIES,
    OBLIGATIONS OR LIABILITIES, OR SUCH CLAIMS, 

                                       21

    ACTIONS, CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS OR EXPENSES
    ARISE OUT OF (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE NEGLIGENCE,
    CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT
    INCLUDING GROSS NEGLIGENCE) OF ANY INDEMNIFIED PARTY, OR (ii) STRICT
    LIABILITY.

    14. NO COMMISSIONS OWED.  Seller agrees to indemnify and hold harmless
        -------------------                                               
Buyer (and its affiliates, and its and their respective officers, directors,
employees, attorneys, contractors and agents) from and against any and all
claims, actions, causes of action, liabilities, damages, losses, costs or
expenses (including, without limitation, court costs and attorneys fees) of any
kind or character arising out of or resulting from any agreement, arrangement or
understanding alleged to have been made by, or on behalf of, Seller with any
broker or finder in connection with this Agreement or the transaction
contemplated hereby.  Buyer agrees to indemnify and hold harmless Seller (and
its affiliates and its and their respective officers, directors, employees,
attorneys, contractors and agents) from and against any and all claims, actions,
causes of action, liabilities, damages, losses, costs or expenses (including,
without limitation, court costs and attorneys fees) of any kind or character
arising out of or resulting from any agreement, arrangement or understanding
alleged to have been made by, or on behalf of, Buyer with any broker or finder
in connection with this Agreement or the transaction contemplated hereby.

    15. CASUALTY LOSS.  In the event of damage by fire or other casualty to
        -------------                                                      
the Properties prior to the Closing, this Agreement shall remain in full force
and effect, and in such event

        (a)  OIL AND GAS PROPERTIES.  As to each such Property so damaged which
             ----------------------                                            
    is an Oil and Gas Property, then (unless Seller elects to repair such
    damage, which Seller shall have no obligation to do, in which case all
    rights to insurance proceeds, and claims against third parties, related
    thereto shall belong to Seller), at Buyer's election, either (i) such
    Property shall be treated as if it had an Asserted Defect associated with it
    and the procedure provided for in Section 8 shall be applicable thereto (in
    which case, unless Buyer and Seller agree to the contrary, all rights to
    insurance proceeds, and claims against third parties, related thereto shall
    belong to Seller), or (ii) the Purchase Price will not be adjusted, and
    Seller shall, at Seller's election, either collect (and when collected pay
    over to Buyer) any insurance claims related to such damage, or assign to
    Buyer such insurance claims, and, in either event, Buyer shall take title to
    the Property affected by such loss without reduction of the Purchase Price.

        (b)  OTHER PROPERTIES.  As to each such Property so damaged which is
             ----------------                                               
    other than an Oil and Gas Property, Seller shall, at Seller's election,
    either (i) repair such damage or replace such Property, (ii) collect for
    (and when collected pay over to Buyer) any insurance claims related to such
    damage, or (iii) assign to Buyer any

                                       22
<PAGE>
 
    insurance claims related to such damage, and Buyer shall take title to the
    Property affected by such loss without reduction of the Purchase Price.

Seller has no obligation to carry insurance coverage (or, if it carries
insurance, to keep such insurance in force or to carry any particular types or
amounts of coverage), and in the event of a loss which is not covered by
insurance, Seller shall have no obligation to Buyer with respect thereto.

    16. NOTICES.  All notices and other communications required under this
        -------                                                           
Agreement shall (unless otherwise specifically provided herein) be in writing

by registered or certified mail (postage prepaid), at the following addresses:

    If to Buyer:  475 17th Street, Suite 1500

                                     Attn:  Law Department

Seller may specify as its proper address any other post office address within
the continental limits of the United States by giving notice to the other party,
in the manner provided in this Section, at least ten (10) days prior to the
effective date of such change of address.

    17. SURVIVAL OF PROVISIONS, LIMITATION ON DAMAGES.  All representations
        ---------------------------------------------                      
and warranties made herein by Buyer and Seller shall be continuing and shall be
true and correct on and as of the date of Closing with the same force and effect
as if made at that time (and shall inure to the benefit of the respective
successors and assigns of Buyer and Seller), and all of such representations and
warranties shall survive the Closing and the delivery of the Conveyance
indefinitely.  The provisions of Section 11 (to the extent the same are, by
mutual agreement, not performed at Closing), and Sections 12, 13(a), 13(c), 14,
16, 17 and 18 shall (subject to any limitations set forth therein) survive the
Closing and delivery of the Conveyance indefinitely.  The provisions of Section
13(b) shall terminate two (2) years after Closing (except with respect to claims
definitively identified by Buyer, by notice in writing to Seller, prior to the
expiration of such two (2) years 

                                       23
<PAGE>
 
period) (the obligations which are limited as to survival by this sentence are
hereinafter called "CERTAIN SURVIVING OBLIGATIONS"). As additional limitations,
Seller shall (a) have no liability for the Certain Surviving Obligations until
the amount of the Certain Surviving Obligations exceeds an amount ("DEDUCTIBLE
AMOUNT") equal to three percent (3%) of the Base Purchase Price, and then Seller
shall be liable for the Certain Surviving Obligations only to the extent they
exceed such Deductible Amount, and (b) have no liability for the Certain
Surviving Obligations to the extent the total of the Certain Surviving
Obligations would exceed (exclusive of the Deductible Amount) an amount equal to
seven percent (7%) of the Base Purchase Price. Notwithstanding anything herein
which may appear to the contrary, (i) neither party shall have any obligations
with respect to this Agreement or the transaction contemplated hereby for any
special, consequential or punitive damages and (ii) Seller's liability with
respect to this Agreement and the transaction contemplated hereby shall never
exceed the Purchase Price (less any amounts credited against the Purchase Price
pursuant to Section 12).

    18. MISCELLANEOUS MATTERS.
        --------------------- 

        (a)  FURTHER ASSURANCES.  After the Closing, Seller and Buyer shall
             ------------------                                            
    execute and deliver, and shall otherwise cause to be executed and delivered,
    from time to time, such further instruments, notices, division orders,
    transfer orders and other documents, and do such other and further acts and
    things, as may be reasonably necessary to more fully and effectively grant,
    convey and assign the Properties to Buyer and to otherwise carry out the
    transaction contemplated hereby.

        (b)  LIKE KIND EXCHANGE.  Seller may elect to structure this transaction
             ------------------                                                 
    as a like-kind exchange pursuant to section 1031 of the Internal Revenue
    Code of 1986, as amended, and the regulations promulgated thereunder, with
    respect to any or all of the Properties (a "LIKE-KIND EXCHANGE") at any time
    prior to the date of Closing. In order to effect a Like-Kind Exchange, Buyer
    shall cooperate and do all acts as may be reasonably required or requested
    by Seller with regard to effecting the Like-Kind Exchange, including, but
    not limited to, permitting Seller to assign its rights under this Agreement
    to a qualified intermediary of Seller's choice in accordance with Treasury
    Regulation (S) 1.1031(k)-1(g)(4) or executing additional escrow
    instructions, documents, agreements or instruments to effect an exchange;
    provided, however, Buyer shall incur no expense in connection with such 
    Like-Kind Exchange and Buyer shall not be required to take title to any
    property other than the Properties in connection with the Like-Kind
    Exchange, and Buyer's possession of the Properties will not be delayed by
    reason of any such Like-Kind Exchange.

        (c)  GAS IMBALANCES, MAKEUP OBLIGATIONS.  Without limitation on any 
             ----------------------------------                         
    other provision of this Agreement, it is expressly understood and agreed
    that, upon the occurrence of Closing, but effective as of the Effective
    Date, Buyer shall succeed to and assume the position of Seller with respect
    to all gas imbalances and make-up obligations related to the Properties
    (regardless of whether such imbalances or make-up obligations arise at the
    wellhead, pipeline, gathering system or other level, and

                                       24
<PAGE>
 
    regardless of whether the same arise under contract or otherwise). As a
    result of such succession, Buyer shall (i) be entitled to receive any and
    all benefits which Seller would have been entitled to receive by virtue of
    such position (including, without limitation, rights to produce and receive
    volumes of production in excess of volumes which it would otherwise be
    entitled to produce and receive by virtue of ownership of the Properties and
    rights to receive cash balancing payments), and (ii) be obligated to suffer
    any detriments which Seller would have been obligated to suffer by virtue of
    such position (including, without limitation, the obligation to deliver to
    others production volumes which would have otherwise been attributable to
    its ownership of the Properties, to deliver production to purchasers hereof
    without receiving full payment therefor, or to make cash balancing payments
    or to repay take or pay payments) and (iii) shall be responsible for any and
    all royalty obligations with respect to such imbalances (including, without
    limitation, any of the same arising out of royalties having been paid on an
    "entitlements" basis rather than a "receipts" basis).

        (d)  DECEPTIVE TRADE PRACTICES WAIVER.  To the extent applicable to the
             --------------------------------                                  
    transaction contemplated hereby or any portion thereof, Buyer waives the
    provisions of the Texas Deceptive Trade Practices Act (Sections 17.41
    through 17.63, inclusive of the Texas Business and Commerce Code, other than
    Section 17.555 which is not waived, and any comparable act in any other
    state in which the Properties are located. In connection with such waiver,
    Buyer hereby represents warrants to Seller that Buyer (i) is in the business
    of seeking or acquiring by purchase or lease, goods, or services, for
    commercial or business use, (ii) has knowledge and experience in financial
    and business matters that enable it to evaluate the merits and risks of the
    transaction contemplated hereby, (iii) is not in a significantly disparate
    bargaining position and (iv) has assets of $5,000,000 or more according to
    its most recent financial statement.

        (e)  PARTIES BEAR OWN EXPENSES.  Each party shall bear and pay all
             -------------------------                                    
    expenses (including, without limitation, legal fees) incurred by it in
    connection with the transaction contemplated by this Agreement.

        (f)  NO SALES TAXES.  No sales, transfer or similar tax will be 
             --------------                         
    collected at Closing from Buyer in connection with this transaction. If,
    however, this transaction is later deemed to be subject to sales, transfer
    or similar tax, for any reason, Buyer agrees to be solely responsible, and
    shall indemnify and hold Seller (and its affiliates, and its and their
    directors, officers, employees, attorneys, contractors and agents) harmless,
    for any and all sales, transfer or other similar taxes (including related
    penalty, interest or legal costs) due by virtue of this transaction on the
    Properties transferred pursuant hereto and the Buyer shall remit such taxes
    at that time. Seller and Buyer agree to cooperate with each other in
    demonstrating that the requirements for exemptions from such taxes have been
    met.

                                       25

        (g)  ENTIRE AGREEMENT.  This Agreement contains the entire understanding
             ----------------                                                   
    of the parties hereto with respect to subject matter hereof and supersedes
    all prior agreements, understandings, negotiations, and discussions among
    the parties with respect to such subject matter; provided that any
    Confidentiality Agreement executed by Buyer and Seller in connection with
    the transaction contemplated hereby remains in full force and effect and is
    not superseded or modified by this Agreement.

        (h)  AMENDMENTS, WAIVERS.  This Agreement may be amended, modified,
             --------------------                                          
    supplemented, restated or discharged (and provisions hereof may be waived)
    only by an instrument in writing signed by the party against whom
    enforcement of the amendment, modification, supplement, restatement or
    discharge (or waiver) is sought.

        (i)  NO PRESS RELEASES.  Except as may be required under applicable law,
             -----------------                                                  
    prior to Closing neither party shall make any public announcement with
    respect to the transaction contemplated hereby without the consent of the
    other party.

        (j)  CHOICE OF LAW.  Without regard to principles of conflicts of law,
             -------------                                                    
    this Agreement shall be construed and enforced in accordance with and
    governed by the laws of the state of Texas applicable to contracts made and
    to be performed entirely within such state and the laws of the United States
    of America, except that, to the extent that the law of a state in which a
    portion of the Properties is located (or which is otherwise applicable to a
    portion of the Properties) necessarily governs, the law of such state shall
    apply as to that portion of the property located in (or otherwise subject to
    the laws of) such state.

        (k)  HEADINGS, TIME OF ESSENCE, ETC.  The descriptive headings contained
             ------------------------------                                     
    in this Agreement are for convenience only and shall not control or affect
    the meaning or construction of any provision of this Agreement.  Within this
    Agreement words of any gender shall be held and construed to cover any other
    gender, and words in the singular shall be held and construed to cover the
    plural, unless the context otherwise requires.  Time is of the essence in
    this Agreement.

        (l)  NO ASSIGNMENT.  Neither party shall have the right to assign its
             -------------                                                   
    rights under this Agreement, without the prior written consent of the other
    party first having been obtained.

        (m)  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding on and
             ----------------------                                         
    inure to the benefit of the parties hereto and their respective successors
    and permitted assigns.

        (n)  COUNTERPART EXECUTION.  This Agreement may be executed in
             ---------------------                                    
    counterparts, all of which are identical and all of which constitute one and
    the same instrument. It shall not be necessary for Buyer and Seller to sign
    the same counterpart.

1.   THE DEPARTMENT OF JUSTICE.
     ------------------------- 

     The Department of Justice and the Office of the Inspector General of the
     Department of the Interior are conducting an industry-wide investigation of
     whether producers have violated the False Claims Act in connection with
     underpayments of royalties for extraction of oil or gas on federal or
     Indian lands since 1986. Through a letter dated 02/03/97, the Department
     requested production of certain information on a voluntary basis.  Buyer
     recognizes these matters may affect its ownership after the Effective Date.

                               SCHEDULE 7(b)(vi)

           [Environmental matters that will not constitute "Defects"]


Without agreeing that the following matters are material within the meaning of
Section 7(b)(vi), the following items are disclosed:


1.   A field office away from the compressor plant has not yet been constructed
     although Seller has obtained approval from the BLM for a new field office.

2.   The APD's have expired on the Balcron Federal #43-26 and #42014J wells for
     which the drilling locations were constructed.  These locations must be
     reclaimed by November 15, 1997 unless a new APD is submitted for them.

3.   Operation of the AJAX DPC 300 rental compressor at the Monument Butte gas
     plant is only approved until October 10, 1997.  Tentative plans are to
     replace this unit with a larger AJAX DPC 600 compressor and a permit has
     been obtained for this modification.  The new operator will either have to
     install the new compressor or obtain approval to continue using the smaller
     engine (this should not be difficult since they approved the larger
     engine).  If installed, the new compressor will been to be source tested
     after installation.

4.   Air emissions permitting has not been done for any production facilities
     other than the gas plant.  However, Seller been working with State DAQ
     through the Utah Petroleum Association to establish a practical system for
     facility registrations.  The state is aware that few oil and gas production
     facilities are permitted and they need special provisions to accommodate
     our industry.
