ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS.

     On June 30, 1998, The Meridian Resource Corporation, a Texas corporation
(the "Company"), effected the acquisition of Louisiana Onshore Properties
Inc., a Delaware corporation ("LOPI"), an indirect subsidiary of Shell Oil
Company ("Shell"), through a merger (the "Merger") of a wholly owned
subsidiary of the Company with and into LOPI (the "LOPI Transaction"). The
Merger was effected pursuant to an Agreement and Plan of Merger dated as of
March 27, 1998 (the "Merger Agreement"), by and among the Company, LOPI
Acquisition Corp., a wholly owned Delaware subsidiary of the Company ("TMR
Sub"), Shell Louisiana Onshore Properties Inc., a Delaware corporation
("SLOPI"), and LOPI, a wholly-owned subsidiary of SLOPI. The Company issued
12,082,030 shares of its common stock, $.01 par value (the "Common Stock") and
shares of a new issue of convertible preferred stock of the Company (the
"Preferred Stock") that is convertible into 12,837,428 shares of Common Stock
as consideration in the Merger. The consideration exchanged in the Merger was
based on arms-length negotiations between the parties.

     On June 30, 1998, in a transaction separate from the LOPI Transaction, the
Company acquired from Shell Western E&P Inc., an indirect subsidiary of Shell
("SWEPI"), various other oil and gas property interests for a total of $42.5
million in cash, subject to adjustment for production, expenses and other items
since October 1, 1997 (the "SWEPI Acquisition" and with the LOPI Transaction,
the "Shell Transactions"). The SWEPI Acquisition was funded pursuant to
advances under the Company's existing credit facility. The purchase price for
the properties acquired in the SWEPI Acquisition was determined through
arms-length negotiations between the parties.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholder of
Louisiana Onshore Properties Inc.

We have audited the accompanying Historical Statement of Revenues and Direct
Operating Expenses of the oil and gas properties (the "Acquisition
Properties") of Louisiana Onshore Properties Inc. for the years ended December
31, 1997, 1996 and 1995. This historical statement is the responsibility of
Louisiana Onshore Properties Inc. Our responsibility is to express an opinion on
this historical statement 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 historical statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
amounts and disclosures in the historical statement. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the historical
statement. We believe that our audits provide a reasonable basis for our
opinion.

The accompanying statement was prepared as described in Note 1 for the purpose
of complying with certain rules and regulations of the Securities and Exchange
Commission (SEC) for inclusion in certain SEC regulatory reports and filings of
The Meridian Resource Corporation and are not intended to be a complete
presentation of the revenues and direct operating expenses of the Acquisition
Properties.

In our opinion, the historical statement referred to in the first paragraph of
this report presents fairly, in all material respects, the revenues and direct
operating expenses of the Acquisition Properties described in Note 1 for the
years ended December 31, 1997, 1996 and 1995, in conformity with generally
accepted accounting principles.

                           DIRECT OPERATING EXPENSES

1.  BASIS OF PRESENTATION

     In October 1997, Louisiana Onshore Properties Inc. ("LOPI") was formed
and interests in certain oil and gas properties owned by one or more
consolidated subsidiaries of Shell Oil Company were conveyed to LOPI (the "LOPI
Properties"). In December 1997, LOPI signed a Letter of Intent to enter into a
merger agreement with The Meridian Resources Corporation ("TMRC") whereby, if
the transaction closes, LOPI, inclusive of the LOPI Properties, will be acquired
by TMRC in exchange for stock of TMRC. As used herein, "Shell" shall refer to
Shell Oil Company or one or more of its consolidated subsidiaries or a
combination of Shell Oil Company and one or more of its consolidated
subsidiaries, as the context requires.

     No segregated accounting records for LOPI existed prior to its formation
and, due to its fully consolidated status with Shell and its pending sale, no
attempt has been made to prepare a balance sheet and income statement for LOPI
as a stand alone entity.

     The revenues and direct operating expenses associated with the LOPI
Properties can be derived from the Shell accounting records. Revenues and direct
operating expenses, as set forth in this financial statement, include oil and
gas revenues and associated direct operating expenses related to the net revenue
interest and net working interest, respectively, in the LOPI Properties. Each
owner recognizes revenue and expenses based on its proportionate share of the
related production and costs. The statement includes oil and gas revenues, net
of royalties. Expenses include labor, repairs and maintenance, fuel consumed and
supplies utilized to operate and maintain the wells and related equipment and
facilities, production taxes and ad valorem taxes.

     This statement varies from an income statement in that it does not show
certain expenses which were incurred in connection with ownership of the LOPI
Properties -- including general and administrative expenses and income taxes.
These costs were not separately allocated to the LOPI Properties in the Shell
accounting records and any pro forma allocation would be both time consuming and
expensive and would not be a reliable estimate of what these costs would
actually have been had LOPI been operated historically as a stand alone entity.
In addition, these allocations, if made using historical Shell general and
administrative structures and tax burdens, would not produce allocations that
would be indicative of the historical performance of the LOPI Properties had
they been assets of TMRC, due to the greatly varying size, structure, operations
and accounting of the two companies. This statement also does not include
provisions for depreciation, depletion and amortization as such amounts would
not be indiciative of those costs which would be incurred by TMRC upon
allocation of the purchase price.

     For the same reason, primarily the lack of segregated or easily obtainable
reliable data on asset values and related liabilities, a balance sheet is not
presented for LOPI.

     Pursuant to the terms of the Agreement and Plan of Merger by and among The
Meridian Resource Corporation, LOPI Acqusition Corporation, Shell Louisiana
Onshore Properties Inc. and Louisiana Onshore Properties Inc. dated March 27,
1998, as amended, Shell has agreed to assume all identified and scheduled
existing liabilities related to LOPI.

     At the end of the economic life of these fields, certain restoration and
abandonment costs will be incurred by the respective owners of these fields. No
accrual for these costs is included in the direct operating expenses.

     The interim financial data for the three months ended March 31, 1998 and
March 31, 1997 is unaudited; however, in the opinion of LOPI, the interim data
includes all adjustments, consisting only of normal recurring adjustments,
necessary for a fair statement of the results for the interim periods.

                    DIRECT OPERATING EXPENSES -- (CONTINUED)

2.  GAS BALANCING

     With respect to gas sales, the entitlement method is used for recording
revenues. Under this approach, revenues are based on the LOPI Properties'
proportionate share of the related production. When sales volumes of the LOPI
Properties exceed the LOPI Properties' entitled share of production, an
over-produced imbalance occurs and a liability is recorded. At December 31,
1997, the LOPI Properties were in a net overproduced position of 390,300 mcf
which is valued at $1,031,559.

3.  RELATED PARTY TRANSACTIONS

     Affiliates of Shell acquired substantially all of the crude oil and natural
gas production from the LOPI Properties for each of the years in the three year
period ended December 31, 1997. Such sales, which include the net revenue
interest of the LOPI Properties as well as associated royalties, amounted to
$92,587,354, $100,188,481 and $101,744,473 for the years ended December 31,
1997, 1996 and 1995, respectively.

SUPPLEMENTARY OIL AND GAS INFORMATION (UNAUDITED)

  PROVED RESERVE ESTIMATES

     Oil and gas proved reserves cannot be measured exactly. Reserve estimates
are based on many factors related to reservoir performance which require
evaluations by the engineers interpreting the available data, as well as price
and other economic factors. The reliability of these estimates at any point in
time depends on both the quality and quantity of the technical and economic
data, the production performance of the reservoirs, as well as extensive
engineering judgment. Consequently, reserve estimates are subject to revision as
additional data becomes available during the producing life of a reservoir. When
a commercial reservoir is discovered, proved reserves are initially determined
based on limited data from the first well or wells. Subsequent data may better
define the extent of the reservoir and additional production performance, well
tests and engineering studies will likely improve the reliability of the reserve
estimate. The evolution of technology may also result in the application of
improved recovery techniques such as supplemental or enhanced recovery projects,
or both, which have the potential to increase reserves beyond those envisioned
during the early years of a resevoir's producing life. Revisions to reserves are
based on engineering analysis of individual reservoirs at the field level.

     Proved reserves are those quantities which, upon analysis of geological and
engineering data, appear with reasonable certainty to be recoverable in the
future from known oil and gas reservoirs under current prices and costs as of
the date the estimate is made. For major revisions, extensions and discoveries,
proved reserves must also be recoverable under future prices and costs
forecasted by Shell. Proved developed reserves are those reserves which can be
expected to be recovered through existing wells with existing equipment and
operating methods. Proved undeveloped reserves are those reserves which are
expected to be recovered from new wells on undrilled acreage or from existing
wells where a relatively major expenditure is required. Net proved reserves
represent the estimated recoverable volumes after deducting from gross reserves
the portion due land owners or others as royalty or operating interests.

     Estimates of proved reserves include and rely upon a production and
development plan and strategy. Shell premises certain expenditures will be made
to produce incremental barrels in the last years of mature fields such as the
LOPI Properties. This represents Shell's philosophy to generally produce all
incremental reserves which can be produced profitabily. If such expenditures are
not made, such volumes will not be produced. Thus, these reserve estimates are
valid only if Shell's operating plan is followed and planned expenditures are
made. In any case, many factors such as unanticipated technical problems or
changes in prices or costs or errors in sound technical judgment made on the
best information available may cause actual production to vary significantly
from estimated reserves.

     Net proved reserves represent the estimated recoverable volumes after
deducting from gross proved reserves the portion due land owners or others as
royalty or operating interests.

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
AND GAS RESERVES

     The following disclosures concerning the standardized measure of future
cash flows from proved oil and gas reserves are presented in accordance with the
Statement of Financial Accounting Standards No. 69. As prescribed by this
statement, the amounts shown are based on prices and costs at the end of each
period and a 10 percent annual discount factor. Since prices and costs do not
remain static, and no price or cost changes have been considered, the results
are not necessarily indicative of the fair market value of estimated proved
reserves, but they do provide a common benchmark which may enhance the users'
ability to project future cash flows.

     Extensive judgments are involved in estimating the timing of production and
the costs that will be incurred throughout the remaining lives of these fields.
Therefore, the results may not be comparable to estimates disclosed by other oil
and gas producers.

To the Board of Directors and Stockholder of
Shell Western E&P Inc.

We have audited the accompanying Historical Statement of Revenues and Direct
Operating Expenses of the oil and gas properties (the "Acquisition
Properties") of Shell Western E&P Inc. for the years ended December 31, 1997,
1996 and 1995. This historical statement is the responsibility of Shell Western
E&P Inc. Our responsibility is to express an opinion on this historical
statement 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 historical statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
amounts and disclosures in the historical statement. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the historical
statement. We believe that our audits provide a reasonable basis for our
opinion.

The accompanying statement was prepared as described in Note 1 for the purpose
of complying with certain rules and regulations of the Securities and Exchange
Commission (SEC) for inclusion in certain SEC regulatory reports and filings of

1.  BASIS OF PRESENTATION

     In December 1997, Shell Western E&P, Inc. (the "Company") signed a letter
of intent to sell the Company's interest in Gibson-Humphreys and Turtle Bayou
(the "SWEPI Properties") to The Meridian Resources Corporation ("TMRC") for
$42.5 million.

     No segregated accounting records for the SWEPI Properties exist as the
SWEPI Properties are fully consolidated with Shell Oil Company and no attempt
has been made to prepare a balance sheet and income statement for the SWEPI
Properties similar to a stand alone entity. As used herein, "Shell" shall
refer to Shell Oil Company or one or more of its consolidated subsidiaries or a
combination of Shell Oil Company and one or more of its consolidated
subsidiaries, as the context requires.

     The revenues and direct operating expenses associated with the SWEPI
Properties can be derived from the Shell accounting records. Revenues and direct
operating expenses, as set forth in this financial statement, include oil and
gas revenues and associated direct operating expenses related to the net revenue
interest and net working interest, respectively, in the SWEPI Properties. Each
owner recognizes revenue and expenses based on its proportionate share of the
related production and costs. The statement includes oil and gas revenues, net
of royalties. Expenses include labor, repairs and maintenance, fuel consumed and
supplies utilized to operate and maintain the wells and related equipment and
facilities, production taxes and ad valorem taxes.

     This statement varies from an income statement in that it does not show
certain expenses which are incurred in connection with ownership of the SWEPI
Properties -- most notably general and administrative expenses and income taxes.
These costs were not separately allocated to the SWEPI Properties in the Shell
accounting records and any pro forma allocation would be both time consuming and
expensive and would not be a reliable estimate of what these costs would
actually have been had the SWEPI Properties been operated historically as a
stand alone entity. In addition, these allocations, if made using historical
Shell general and administrative structures and tax burdens, would not produce
allocations that would be indicative of the historical performance of the SWEPI
Properties had they been assets of TMRC, due to the greatly varying size,
structure, operations and accounting of the two companies. This statement also
does not include provisions for depreciation, depletion and amortization as such
amounts would not be indicative of those costs which would be incurred by TMRC
upon allocation of the purchase price.

     For the same reason, primarily the lack of segregated or easily obtainable
reliable data on asset values and related liabilities, a balance sheet is not
presented for the SWEPI Properties.

     At the end of the economic life of these fields, certain restoration and
abandonment costs will be incurred by the respective owners of these fields. No
accrual for these costs is included in the direct operating expenses.

     The interim financial data for the three months ended March 31, 1998 and
March 31, 1997 is unaudited; however, in the opinion of the Company, the interim
data includes all adjustments, consisting only of normal recurring adjustments,
necessary for a fair statement of the results for the interim periods.

2.  GAS BALANCING

     With respect to gas sales, the entitlement method is used for recording
revenues. Under this approach, revenues are based on the SWEPI Properties'
proportionate share of the related production. When sales volumes of the SWEPI
Properties exceed the Company's entitled share of production, an over-produced

                 NOTES TO HISTORICAL STATEMENT OF REVENUES AND
                    DIRECT OPERATING EXPENSES -- (CONTINUED)

imbalance occurs and a liability is recorded. At December 31, 1997, the SWEPI
Properties were in a net overproduced position of 695,526 mcf which is valued at
$1,739,837.

3.  RELATED PARTY TRANSACTIONS

     Affiliates of Shell acquired substantially all of the crude oil and natural
gas production from the SWEPI Properties for each of the years in the three year
period ended December 31, 1997. Such sales, which include the net revenue
interest of the SWEPI Properties as well as associated royalties, amounted to
$12,660,277, $18,752,521 and $12,927,216 for the years ended December 31, 1997,
1996 and 1995, respectively.

SUPPLEMENTARY OIL AND GAS INFORMATION (UNAUDITED)

  PROVED RESERVE ESTIMATES

     Oil and gas proved reserves cannot be measured exactly. Reserve estimates
are based on many factors related to reservoir performance which require
evaluations by the engineers interpreting the available data, as well as price
and other economic factors. The reliability of these estimates at any point in
time depends on both the quality and quantity of the technical and economic
data, the production performance of the reservoirs, as well as extensive
engineering judgment. Consequently, reserve estimates are subject to revision as
additional data becomes available during the producing life of a reservoir. When
a commercial reservoir is discovered, proved reserves are initially determined
based on limited data from the first well or wells. Subsequent data may better
define the extent of the reservoir and additional production performance, well
tests and engineering studies will likely improve the reliability of the reserve
estimate. The evolution of technology may also result in the application of
improved recovery techniques such as supplemental or enhanced recovery projects,
or both, which have the potential to increase reserves beyond those envisioned
during the early years of a reservoir's producing life. Revisions to reserves
are based on engineering analysis of individual reservoirs at the field level.

     Proved reserves are those quantities which, upon analysis of geological and
engineering data, appear with reasonable certainty to be recoverable in the
future from known oil and gas reservoirs under current prices and costs as of
the date the estimate is made. For major revisions, extensions and discoveries,
proved reserves must also be recoverable under future prices and costs
forecasted by Shell. Proved developed reserves are those reserves which can be
expected to be recovered through existing wells with existing equipment and
operating methods. Proved undeveloped reserves are those reserves which are
expected to be recovered from new wells on undrilled acreage or from existing
wells where a relatively major expenditure is required. Net proved reserves
represent the estimated recoverable volumes after deducting from gross proved
reserves the portion due land owners or others as royalty or operating
interests.

     Estimates of proved reserves include and rely upon a production and
development plan and strategy. Shell premises certain expenditures will be made
to produce incremental barrels in the last years of mature fields such as the
SWEPI Properties. This represents Shell's philosophy to generally produce all
incremental reserves which can be produced profitably. If such expenditures are
not made, such volumes will not be produced. Thus, these reserve estimates are
valid only if Shell's operating plan is followed and planned expenditures are
made. In any case, many factors such as unanticipated technical problems or
changes in prices or costs or errors in sound technical judgement made on the
best information available may cause actual production to vary significantly
from estimated reserves.

Gas (per Mcf)........................  $    2.62  $    4.05  $    1.85

     Crude oil and natural gas price realizations for the SWEPI Properties at
March 31, 1998 were $12.59 per Bbl and $2.31 per Mcf, respectively.

     The aggregate change in the Standardized Measure of discounted future net
cash flows was a decrease of $85,500,000 in 1997, an increase of $52,245,000 in
1996 and an increase of $10,561,000 in 1995. The principal sources of change for
the years ended December 31 were as follows (in thousands):

                                          1997        1996        1995

                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS

     The LOPI Transaction was consummated on June 30, 1998. The SWEPI
Acquisition was consummated immediately after the consummation of the LOPI
Transaction. The Unaudited Pro Forma Statements of Operations for the year ended
December 31, 1997 and the three months ended March 31, 1998 give effect to the
LOPI Transaction and the SWEPI Acquisition as if each had occurred on January 1,
1997 and January 1, 1998, respectively, and the Unaudited Pro Forma Balance
Sheet gives effect to the LOPI Transaction and SWEPI Acquisition as if each had
occurred on March 31, 1998.

     The Unaudited Pro Forma Statements of Operations and Unaudited Pro Forma
Balance Sheet should be read in conjunction with the notes thereto and the
historical financial statements of the Company and the statements of revenues
and direct operating expenses of the Shell Properties and the notes thereto
included elsewhere in this Proxy Statement.

     The pro forma adjustments to give effect to the various events described
above are based upon currently available information and upon certain
assumptions that management of the Company believes are reasonable. The LOPI
Transaction and the SWEPI Acquisition will be accounted for by the Company under
the purchase method of accounting, and the assets and liabilities of LOPI and
the oil and gas property interests and other assets acquired in the SWEPI
Acquisition will be recorded at their estimated fair market values at the date
of their respective acquisitions. The adjustments included in the Unaudited Pro
Forma Statements of Operations and in the Unaudited Pro Forma Balance Sheet
reflect the Company's preliminary determination of these and other necessary
adjustments based upon available information. There can be no assurance that the
actual adjustments will not vary significantly from the estimated adjustments
reflected in the Unaudited Pro Forma Statements of Operations and Unaudited Pro
Forma Balance Sheet.

     The unaudited pro forma combined financial information does not purport to
be indicative of the financial position or results of operations that would
actually have occurred if both the LOPI Transaction and the SWEPI Acquisition
had occurred as presented in such statements or that may be obtained in the
future. In addition, future results may vary significantly from the results
reflected in such statements due to general economic conditions, oil and gas
commodity prices, the Company's ability to successfully integrate the operations
acquired in the recent merger with Cairn and in the Shell Transactions and
several other factors beyond the Company's control as more fully described in
the Company's Annual Report on Form 10-K for the year ended December 31, 1998.

               NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

      (A)  To record the purchase price of $329.1 million in connection with the
merger with LOPI and the acquisition of the SWEPI Properties, consisting of ($
in millions, except per share and stated value data):

    $42.5  Cash
    135.0  Issuance of Preferred Stock ($135 million stated value)
     96.1  Issuance of 12,082,030 shares of Common Stock at $7.96 per share
      2.8  Assumption of certain liabilities
     52.7  Deferred income taxes related to acquired properties
- ---------
   $329.1
=========

           Note: The $7.96 per share value of Common Stock is based on the
                 average closing price of the Common Stock on the NYSE several
                 days before and after execution of the LOPI Agreement.

      (B)  To record $42.5 million of additional borrowings to finance the cash
consideration paid for the SWEPI Properties.

      (C)  To record adjustment relating to the impairment charge and deferred
income taxes related to the Shell Properties.

      (D)  To adjust depreciation and depletion expense related to the
acquisition of the Shell Properties.

      (E)  The unaudited pro forma statements of operations do not include any
adjustments relating to additional general and administrative expenses that
would have been incurred by the Company during the year ended December 31, 1997
and the three months ended March 31, 1998, had the Shell Transactions been
consummated on January 1, 1997. The Company currently estimates that general and
administrative expenses will increase annually by approximately $3.5 million to
$4.0 million following consummation of the Shell Transactions.

      (F)  To record interest on additional borrowings of $42.5 million to
finance the cash consideration paid for the SWEPI Properties.

      (G)  To accrue a 4% dividend on the $135 million stated value of the
Preferred Stock.

      (H)  Since the unaudited pro forma statements of operations indicate a net
loss, conversion of the Preferred Stock is deemed to be antidilutive and is not
considered in the earnings per share calculation. In the event the Company would
have had pro forma net income, the Common Stock to be issued upon conversion of
the Preferred Stock would have been included in the calculation of diluted
earnings per share and would have resulted in a significant reduction in pro
forma diluted earnings per share and pro forma basic earnings per share.

     The following is a summary of pro forma standardized measure of discounted
future net cash flows related to the Company's pro forma proved oil, natural gas
and natural gas liquids reserves and includes the effects of the merger with
LOPI and the acquisition of the SWEPI Properties. The additions to proved
reserves from new discoveries and extension could vary significantly from year
to year. Additionally, the impact of changes to reflect current prices and costs
of reserves proved in prior years could be significant. Accordingly, the
information presented below should neither be viewed as an estimate of the fair
value of the Company's oil and natural gas properties following the Shell
Transactions nor should it be considered indicative of any trends.

(1) The differences in the estimated proved reserves of the Shell Properties, as
    reflected in the Statements of Revenues and Direct Operating Expenses for
    each of the LOPI Properties and the SWEPI Properties (the "Shell Financial
    Statements") and as estimated by T. J. Smith (the Company's independent
    reservoir engineers for the LOPI and SWEPI Properties) relate to, among
    other factors, differences between Shell and the Company in depletion and
    development strategies and related expenditures for proved developed
    reserves. Other reserve differences relate to differing assumptions as to
    decline curves, volumetric analysis and other engineering judgments inherent
    in the reserve estimating process.

    The reserve estimates reflected in the Shell Financial Statements assume
    $199 million in future production and development costs for the Shell
    Properties while T. J. Smith's estimates assume only $114 million of such
    costs will be expended by the Company for such properties. Approximately
    one-half of the difference in estimated future production and development
    costs relates to (i) differences in the amount of expenditures for proved
    developed non-producing reserves, which may be produced from existing wells
    but require additional expenditures for recompletion efforts and related
    operating expenses, and (ii) differences in estimated production costs
    related to reserves that T.J. Smith's estimates do not assume will be
    produced. Shell's expenditure estimates include amounts that, absent the
    Shell Transactions, it anticipated making for future production and
    development of these reserves. Because of the Company's higher cost of
    capital and focus on larger exploration prospects, the Company does not
    currently plan to make such expenditures and produce such reserves. Rather,
    the Company currently intends to concentrate its expenditures with respect
    to the Shell Properties on an accelerated exploration and development
    program that is focused on the unproved properties that the Company believes
    provide higher potential ultimate returns than the lower risk and lower
    volume proved developed properties. The remaining difference in estimated
    expenditures relates primarily to differences in estimated plugging and
    abandonment costs that will be incurred at the conclusion of operation of
    these fields due to differing assumptions between Shell and the Company on
    the plan of abandonment or disposition of the properties prior to
    abandonment.

IT MAY HAVE AGAINST OR FROM SELLER WITH RESPECT TO THE CONDITION OF THE

PROPERTY AND DAMAGE TO NATURAL RESOURCES ASSOCIATED WITH THE PROPERTY (INCLUDING
ANY LIABILITY UNDER CERCLA OR OTHER ENVIRONMENTAL LAWS), WHETHER CONTRACT, TORT
OR STATUTORY IN NATURE, REGARDLESS OF THE NEGLIGENCE, FAULT OR STRICT
(STATUTORY) LIABILITY OF SELLER; (V) PURCHASER SHALL FURTHER ACKNOWLEDGE THAT IT

<PAGE>
      11. INDEPENDENT EVALUATION. PURCHASER has made an independent evaluation
of the PROPERTY and acknowledges that SELLER has made no statements or
representations concerning the present or future value of the anticipated
income, costs, or profits, if any, to be derived from the PROPERTY, the physical
condition of the PROPERTY, the quantity and quality of any oil and gas or other
minerals that may be produced from the PROPERTY, or any other matter with
respect to the PROPERTY and THAT SELLER DOES NOT IMPLICITLY OR EXPRESSLY WARRANT
DESCRIPTION, TITLE, VALUE, QUALITY, PHYSICAL CONDITION OF THE PROPERTY
(INCLUDING, WITHOUT LIMITATION, THE ENVIRONMENTAL CONDITION OF THE PROPERTY),
MERCHANTABILITY, OR FITNESS FOR PURPOSE OF ANY OF THE PROPERTIES OR THE WELLS,
EQUIPMENT, PIPELINES, FACILITIES, OR OTHER PROPERTY LOCATED THEREON OR USED IN
CONNECTION THEREWITH. PURCHASER further acknowledges that, in entering into this
AGREEMENT, it has relied solely upon its independent examination of the PROPERTY
and public records relating to the PROPERTY and its independent estimates,
computations, evaluations, reports and studies based thereon and has not relied
on any representation or statement made by SELLER. SELLER MAKES NO WARRANTY OR
REPRESENTATION AS TO THE ACCURACY, COMPLETENESS OR CORRECTNESS OF ANY
INFORMATION FURNISHED TO PURCHASER. ANY RELIANCE PURCHASER MAKES ON SUCH
INFORMATION IS AT PURCHASER'S SOLE RISK AND SELLER SHALL HAVE NO LIABILITY
WHATSOEVER TO PURCHASER IN CONNECTION THEREWITH.

      12. CONSENTS; PREFERENTIAL RIGHTS. In the event any of the interests to be
conveyed or transferred to PURCHASER as part of the PROPERTY (i) are burdened
with a preferential right in a Third Party to purchase such interest or (ii)
require the consent of a Third Party to assign
<PAGE>
SELLER's interest, then the conveyance or transfer of the interest subject to
such preference or consent shall be conditioned upon SELLER's obtaining the
necessary waiver or consent and this AGREEMENT shall not constitute an
assignment or attempted assignment thereof without such consent or waiver.
Provided, however, if such requirement for Third Party consent is subject to an
express or implied provision to the effect that such consent may not be
unreasonably withheld and SELLER, in its sole discretion, determines that such
consent is being unreasonably withheld, SELLER may, at its risk, assign such
interest to PURCHASER. Except for any liability of SELLER to a Third Party with
respect to an assignment pursuant to the preceding sentence, SELLER shall not be
liable to PURCHASER by reason of any inability or failure to obtain any such
waiver of preferential rights or consent to assignment. PURCHASER shall, at the
request of SELLER, nominate a value to each interest burdened by a preferential
right to purchase, and if such value is agreeable to SELLER, it shall become the
price to such Third Party. If SELLER is unable to obtain a required waiver or
consent, or if a preferential right to purchase is exercised or if SELLER
determines that such consent has been unreasonably withheld but elects not to
assign the interest, then such interest shall be excluded from the PROPERTY and
the Purchase Price shall be reduced by the amount, agreed upon by SELLER and
PURCHASER, as described in the preceding sentence, to account for such interest
unless: (i) PURCHASER AGREES TO ACCEPT THE INTEREST "AS IS", AND RELEASES SELLER
FROM ALL CLAIMS RELATED THERETO, or (ii) SELLER agrees to indemnify PURCHASER
against all losses, costs, expenses and liabilities with respect to such failure
to obtain consent to assign. If no agreed upon reduction in Purchase Price has
been reached and no agreement can otherwise be reached as to the disposition of
an interest for which consent to assign has not been obtained, then either Party
may give written notice to the other Party to terminate this AGREEMENT and upon
the giving of such notice, neither Party shall have any further rights or
obligations hereunder, except for PURCHASER's obligations and SELLER's rights
<PAGE>
under the Confidentiality Agreement dated August 21, 1997. Notwithstanding the
above, it is understood and agreed that the prior termination or lapse of or a
requirement that any license, permit, right-of-way, pipeline franchise or
easement affecting any interests in or other portions of the PROPERTY is
non-transferable, must be renegotiated or is subject to consent upon a transfer
of ownership shall not entitle the PURCHASER to any remedy under this AGREEMENT.

      13. TITLE.

            (a) TITLE EXAMINATION. PURCHASER assumes the risk of description and
title to the PROPERTY and agrees to satisfy itself with respect thereto.
PURCHASER acknowledges and agrees that SELLER MAKES NO WARRANTY OF TITLE WITH
RESPECT TO THE PROPERTY OR ANY PORTION THEREOF, AND NONE SHALL BE IMPLIED.
Pursuant to the Process Description attached to SELLER's Bid Solicitation Letter
of September 4, 1997, SELLER has made available to PURCHASER for examination by
PURCHASER such title information and abstract coverage as may have been
available in SELLER's land and contract files located in Houston, Texas. SELLER
MAKES NO WARRANTY OR REPRESENTATION AS TO THE ACCURACY, COMPLETENESS OR
CORRECTNESS OF ANY TITLE INFORMATION OR OPINIONS FURNISHED TO PURCHASER. ANY
RELIANCE PURCHASER MAKES ON SUCH INFORMATION IS AT PURCHASER'S SOLE RISK AND
SELLER SHALL HAVE NO LIABILITY WHATSOEVER TO PURCHASER IN CONNECTION THEREWITH.

            (b) PERSONAL PROPERTY INVENTORY LIST. If PURCHASER prepares an
inventory list of the personal property being conveyed or transferred hereunder,
such inventory list, if approved by SELLER, shall be controlling with respect to
the personal property listed therein and shall be attached to any Bill of Sale
or other document of conveyance utilized to transfer the personal property from
SELLER to PURCHASER under this AGREEMENT. If PURCHASER does not prepare such an
inventory list,
<PAGE>
then the Bill of Sale or other document of conveyance will omit an inventory
list and recite generally the sale, transfer and conveyance of all of SELLER's
right, title and interest in all specified categories of personal property
located on or associated with the real property and lands subject to the
interests in real property included in the PROPERTY.

CERTIFICATE OF DESIGNATION, PREFERENCES AND RIGHTS OF A SERIES OF PREFERRED
STOCK BY RESOLUTION OF THE BOARD OF DIRECTORS PROVIDING FOR AN ISSUE OF
3,982,906 SHARES OF PREFERRED STOCK DESIGNATED SERIES A CUMULATIVE CONVERTIBLE
PREFERRED STOCK.
================================================================================

      The Meridian Resource Corporation, a Texas Corporation (the "Company"),
pursuant to the provisions of Article 2.12 of the Texas Business Corporation Act
("TBCA"), does hereby state and certify that, pursuant to the authority
expressly vested in the Board of Directors of the Company by the Second Amended
and Restated Articles of Incorporation of the Company, as amended, that the
Board of Directors, at a meeting thereof duly called and held on March 27, 1998,
at which meeting a quorum was present and acting throughout, duly adopted the
following resolutions providing for the issue of shares of Preferred Stock
hereinafter referred to, and further providing with respect to such issue of
shares of Preferred Stock for such powers, designations, preferences and
relative, participating, optional and other special rights, and the
qualifications, limitations or restrictions thereof, as are hereinafter set
forth, in addition to those set forth in said Articles of Incorporation;

      RESOLVED, that pursuant to Article Four of the Second Amended and Restated
Articles of Incorporation of the Company, as amended (which authorizes the
Company to issue up to 25,000,000 shares of Preferred Stock, par value $1.00 per
share), the Board of Directors hereby provides for the issue of a series of up
to 3,982,906 shares of Preferred Stock designated "Series A Cumulative
Convertible Preferred Stock"; and

      RESOLVED, that the powers, designations, preferences and relative,
participating, optional and other special rights, and the qualifications,
limitations or restrictions thereof, of the shares of the Series A Cumulative
Convertible Preferred Stock shall be as follows:

      SECTION 1. DESIGNATION AND RANK. The designation of the series of
Preferred Stock created by this resolution shall be "Series A Cumulative
Convertible Preferred Stock", and the number of shares constituting this Series
shall have a stated value of $33.894850 per share (the "Stated Value"). The
shares of this Series shall rank prior to the Junior Stock (as defined in
Section 8) as to distribution of assets and payments of dividends.
<PAGE>
      SECTION 2. DIVIDENDS.

      (a) Shares of this Series shall be entitled to receive, when and as
declared by the Board of Directors, a cash dividend at the dividend rate of four
percent (4%) per annum (the "Dividend Rate") on the Stated Value per share of
this Series, and no more; provided, however, that dividends shall cease to
accrue on shares of the Series on the following schedule: 1,327,635 shares on
the third anniversary of the date of original issuance (the "Sub-Series A-I");
1,327,636 shares on the fourth anniversary of the date of original issuance (the
"Sub-Series A-II"); and 1,327,635 shares on the fifth anniversary of the date of
original issuance (the "Sub-Series A-III") (collectively, the "Sub-Series"). The
certificates evidencing shares of the Series will specify whether the shares
represented thereby are designated Sub-Series A-I, Sub-Series A-I or Sub- Series
A-III. Dividends shall be cumulative, shall accrue (whether or not declared and
whether or not there shall be funds legally available for the payment of
dividends) from the data of original issuance and shall be payable in arrears,
out of assets legally available therefor, when and as declared by the Board of
Directors of the Company, on January 1, April 1, July 1, and October 1 of each
year in which dividends are payable, commencing October 1, 1998, (except that if
any such date is a Saturday, Sunday or a Business Day then such dividend shall
be payable without interest on the next day that is not a Saturday, Sunday or
Business Day) (each three-month period expiring on a dividend payment date being
referred to herein as a "Dividend Period"). Dividends shall be paid to the
holders of record of shares of each Sub-Series entitled thereto as they appear
on the stock register of the Company on such record dates, not exceeding 30 days
preceding the payment dates thereof, as shall be fixed by the Board of
Directors. Dividends on account of arrears for any past Dividend Periods (an
"Arrearage") may be declared and paid at any time, without reference to any
regular dividend payment date, to holders of record on such date, not exceeding
45 days preceding the payment date thereof, as may be fixed by the Board of
Directors. Until paid in full, each Arrearage shall also accrue dividends at the
rate of 4% per annum. All dividends and Arrearages respectively, shall be
declared and paid pro rata on all Sub-Series, based on the aggregate of the
accrued dividends, Arrearages and dividends on Arrearages, respectively, for the
various Sub-Series.

      (b) No dividends (other than a dividend in Junior Stock or other than as
provided in Section 2(b)) shall be declared or paid or set apart for payment on
Junior Stock for any period unless full cumulative dividends have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for such payment on this Series for all Dividend
Periods terminating on or prior to the date of payment of such full cumulative
dividends Holders of shares of this Series shall not be entitled to any
dividend, whether payable in cash, property or stock, in excess of full
cumulative dividends.

      (c) So long as any shares of this Series are outstanding, no dividend
(other than a dividend in Junior Stock or other than as provided in Section
2(b)) shall be declared or paid or set aside for payment or other distribution
declared or made upon the Junior Stock, nor shall any Junior Stock be redeemed,
purchased or otherwise acquired for any consideration (or any moneys be paid to
or made available for a 

                                      -2-
<PAGE>
sinking fund for the redemption of any shares of Junior Stock) by the Company
(except by conversion into or in exchange for Junior Stock) unless, in each
case, full cumulative dividends on all outstanding shares of this Series then
payable shall have been paid.

      (d) Dividends payable on this Series for a period less than a full
Dividend Period shall be computed on the basis of the ratio of the number of
days in such partial period to the actual number of days in such full Dividend
Period.

      SECTION 3. VOTING AND ELECTION OF DIRECTORS.

      (a) The holders of outstanding shares of this Series shall be entitled to
vote, with the Common Stock and any other capital stock voting with the Common
Stock, with respect to all matters for which a vote of the holders of Common
Stock is taken. Each holder of outstanding shares of this Series shall be
entitled to that number of votes as are equal to the number of shares of this
Series held by such holder. The record date for holders of shares of the Series
entitled to vote on any matters submitted to the holders of Common Stock for
their vote, whether at an annual or special meeting of shareholders or by
unanimous written consent, shall be the same date as the record date established
for the Common Stock.

      (b) So long as any shares of this Series remain outstanding, the
affirmative vote or consent of the holders of a majority of the shares of this
Series outstanding at the time, voting as a single class, given in person or by
proxy, either in writing or at a meeting, shall be necessary to permit, effect
or validate any of the following: (i) the authorization, creation or issuance,
or any increase in the authorized or issued amount, of any class of series of
Senior Stock or Parity Stock (both as defined in Section 8) or (ii) the
amendment, restatement, modification, alteration or repeal of any of the
provisions of this Certificate of Designation.

      (c) Until the earlier of (i) the termination of the Stock Rights and
Restrictions Agreement to be entered into on or about June 30, 1998, as it may
be amended from time to time (the "SLOPI Agreement"), between the Company and
Shell Louisiana Onshore Properties, Inc., a Delaware Corporation ("SLOPI") or
(ii) SLOPI and its Affiliates shall Beneficially Own shares of Common Stock
constituting less than 21% of the then outstanding shares of Common Stock, then,
in connection with each election of directors of the Company, whether at an
annual or special meeting, the holders of this Series shall be entitled to elect
at such meeting a number of directors (the "Preferred Directors") such that,
after giving effect to the election of such persons to the Board of Directors of
the Company, the number of Preferred Directors then serving on the Board of
Directors of the Company shall equal the product (rounded downward to the
nearest whole number, but, in any event, not less than one) of (i) the total
number of directors constituting the entire Board of Directors multiplied by
(ii) 20% (the "Director Percentage").

      (d) If at any time the number of directors constituting the Board of
Directors of the Company shall decrease so that the holders of the Series would
be entitled to designate fewer directors than are then serving as Preferred
Directors, the holders of 

                                      -3-
<PAGE>
the Series, one or more of the Preferred Directors shall resign so that the
percentage of the Board of Directors consisting of Preferred Directors does not
exceed the Director Percentage (rounded downward to the nearest whole number but
in no event less than one); provided, that, if a Preferred Director does not
resign, the members of the Board of Directors who are not Preferred Directors
shall be entitled to remove such Preferred Director. Further, (i) upon
termination of the SLOPI Agreement in accordance with its terms or (ii) the
conversion of all outstanding shares of this Series into Common Stock, all
Preferred Directors then serving as directors of the Company shall immediately
cease to be members of the Company's Board of Directors and shall be deemed to
have resigned on the date of such termination.

      (e) (i) In the event that any Preferred Director shall cease to serve as a
director for any reason (other than as set forth in Section (d) immediately
above), the vacancy resulting thereby shall be filled by appointment by any
Preferred Director remaining, and in the absence of action by the remaining
Preferred Directors, by the holders of the Series, and such Preferred Director
shall thereafter serve until the expiration of the term of the Preferred
Director replaced by such new Preferred Director.

          (ii) Subject to the provisions of Section 3(f) below, if there shall
exist at any time any vacancy or vacancies on the Board of Directors of the
Company as a result of any increase in the number of directors that constitutes
the entire Board of Directors of the Company, which the directors of the Company
then in office intend to fill in accordance with the Company's then existing
Articles of Incorporation, by-laws and applicable law, the holders of the Series
shall be entitled to designate one or more persons to fill such vacancy or
vacancies if and to the extent necessary so that, after giving effect to the
filling of such vacancy or vacancies, the number of Preferred Directors then
serving on the Board of Directors of the Company shall equal the Director
Percentage (rounded downward to the nearest whole number but in no event less
than one).

      (f) Notwithstanding anything to the contrary contained herein, no
Preferred Director may be a person who previously has been a director of the
Company and was properly removed for cause from the Board of Directors of the
Company or a person who has been convicted of a felony or a crime involving
moral turpitude.

      (g) At all times when there is a Preferred Director on the Company's Board
of Directors, at least one shall be a member of each Audit Committee of the
Board of Directors. All members of the Audit Committee shall have access to the
Company's independent accountants and all audit and tax work papers to the same
extent as any other member of the Audit Committee.

      (h) The Preferred Directors will be furnished with all information that is
provided to all other directors of the Company (in their capacities as such) at
the same time as such information is furnished to such other directors (in their
capacities as such).

                                      -4-
<PAGE>
      (i) All Preferred Directors shall comply with the retirement policies of
the Company as in effect on the date hereof or as hereafter amended or modified
from time to time by the Board of Directors of the Company or its stockholders;
provided that no such amendment or modification to such policies shall be
binding upon a Preferred Director unless at least one Preferred Director shall
have voted in favor of such amendment or modification at the meeting, or in the
action in lieu of a meeting, of the Board of Directors of the Company at or in
which it is considered.

      (j) The election of Preferred Directors or approval under paragraph (b)
above shall be by holders of a majority of the issued and outstanding Series as
reflected on the stock books of the Company on the applicable record date, or if
by written consent, on the date of such consent. The record date for holders of
shares of the Series entitled to vote on matters pursuant to this Section 3 at a
meeting of the holders of the Series shall be established by the Board of
Directors of the Company and shall not precede 60 days before such meeting.
Special meetings of the holders of the Series may be called by any holder of
more than 25% of the outstanding shares of the Series, except that the Company
may call a special meeting of the holders of the Series in connection with any
action to be voted on pursuant to paragraph (b) above. Any action taken by
written consent of the holders of the Series need not be unanimous and such
action will be effective upon delivery of such written consent to the Secretary
of the Company.

      SECTION 4. LIQUIDATION. In the event of any complete liquidation,
dissolution or winding-up of the Company, whether voluntary or involuntary the
holders of shares of this Series shall each be entitled to receive out of assets
of the Company, whether such assets are capital or surplus, for each share of
this Series a sum equal to the Stated Value plus the amount of any accrued and
unpaid dividends on such share plus interest accrued but unpaid on any
Arrearage, before any distribution shall be made to the holders of Junior Stock
of the Company, and if the assets of the Company shall be insufficient to pay in
full such amounts, then such assets shall be distributed among the holders of
this Series ratably in accordance with the respective amounts that would be
payable on such shares if all amounts payable thereon were paid in full.

      SECTION 5. CONVERSION.

      (a) Each share of this Series shall be convertible at the option of the
record holder thereof at any time by presentation of the certificate
representing such share by the record holder in person or by registered mail,
return receipt requested with postage prepaid thereof, at the principal office
of the Company, and at such other offices, if any, as the Board of Directors may
determine, into the number of fully paid and nonassessable shares of Common
Stock determined by dividing the Stated Value by the Conversion Price in effect
on the Conversion Date.

      (b) The conversion price initially shall be $10.516125 (the "Conversion
Price") and shall be subject to adjustment from time to time as follows:

                                      -5-
<PAGE>
            (i) If the Company, at any time while any shares of this Series are
      outstanding, shall (A) pay a stock dividend or stock dividends or
      otherwise make a distribution or distributions on shares of its capital
      stock payable in shares of Common Stock (or in securities convertible into
      shares of Common Stock), (B) except as set forth in clause (A) above, pay
      a stock dividend or make a distribution on shares of its capital stock
      payable in shares of its capital stock of any class other than Common
      Stock or a class convertible into Common Stock, (C) subdivide outstanding
      shares of Common Stock into a larger number of shares, (D) combine
      outstanding shares of Common Stock into a smaller number of shares, or (E)
      issue by reclassification of shares of Common Stock any shares of capital
      stock of the Company of any class or classes, the Conversion Price in
      effect immediately prior to such action shall be adjusted so that the
      holder of any shares of this Series thereafter surrendered for conversion
      shall be entitled to receive the number and class or classes of shares of
      the capital stock of the Company which he would have owned or have been
      entitled to receive immediately after the happening of any of the events
      described above, had such shares of this Series been converted on or
      immediately prior to the record date for such dividend or distribution or
      the effective date of such subdivision, combination or reclassification,
      as the case may be. An adjustment made pursuant to this subsection 5(b)(i)
      shall become effective immediately after the record date in the case of a
      dividend or distribution and shall become effective immediately after the
      effective date in the case of a subdivision, combination or
      reclassification.

            (ii) If the Company, at any time while any shares of this Series are
      outstanding, shall issue rights or warrants to all holders of Common Stock
      entitling them (for a period expiring within 45 days after the record date
      mentioned below) to subscribe for or purchase shares of Common Stock at a
      price per share less than the Per Share Market Value of Common Stock at
      the record date mentioned below, the Conversion Price at which each share
      of this Series shall thereafter be convertible shall be reduced by
      multiplying the Conversion Price in effect immediately prior to such
      record date by a fraction, of which the denominator shall be the number of
      shares of Common Stock (excluding treasury shares, if any) outstanding on
      the date of issuance of such rights or warrants plus the number of
      additional shares of Common Stock offered for subscription or purchase,
      and of which the numerator shall be the number of shares of Common Stock
      (excluding treasury shares, if any) outstanding on the date of issuance of
      such rights or warrants plus the number of shares which the aggregate
      offering price of the total number of shares so offered would purchase at
      such Per Share Market Value. Such adjustment shall be made whenever such
      rights or warrants are issued, and shall become effective immediately
      after the record date for the determination of stockholders entitled to
      receive such rights or warrants. However, upon the expiration of any right
      or warrant to purchase Common Stock the issuance of which resulted in an
      adjustment in the Conversion Price of the shares of this Series pursuant
      to this Subsection 5(b)(ii), if any such right or warrant shall expire and
      shall not have been fully exercised, the Conversion Price per share of
      Common Stock at which 

                                      -6-
<PAGE>
      each share of this Series shall thereafter be convertible shall
      immediately upon such expiration be recomputed and effective immediately
      upon such expiration be increased to the price which it would have been
      (but reflecting any other adjustments in the Conversion Price made
      pursuant to the provisions of this Section 6 after the issuance of such
      rights or warrants) had the adjustment of the Conversion Price made upon
      the issuance of such rights or warrants been made on the basis of offering
      for subscription or purchase only that number of shares of Common Stock
      actually purchased upon the exercise of such rights or warrants which were
      actually exercised. No adjustment shall be made pursuant to this Section
      5(b)(ii) if rights and warrants are also distributed to the holders of
      this Series on the basis of the number of shares of Common Stock then
      issuable on conversion of the shares of this Series.

            (iii) If the Company, at any time while shares of this Series are
      outstanding, shall distribute to all holders of Common Stock evidences of
      its indebtedness or assets (excluding cash dividends or cash distributions
      paid out of earned surplus) or rights or warrants to subscribe for or
      purchase any security (excluding those referred to in Subsection 5(b)(ii)
      above) then in each such case the Conversion Price per share of Common
      Stock at which each share of this Series shall thereafter be convertible
      shall be determined by multiplying the Conversion Price in effect
      immediately prior to the record date fixed for determination of
      stockholders entitled to receive such distribution by a fraction, of which
      the denominator shall be the Per Share Market Value of Common Stock
      determined as of the record date mentioned above, and of which the
      numerator shall be such Per Share Market Value of the Common Stock, less
      the then fair market value (as determined by the Board of Directors of the
      Company (the "Board") in good faith, whose determination shall be
      conclusive if made in good faith; provided, however, that in the event of
      a distribution or series of related distributions exceeding 10% of the net
      assets of the Company, then such fair market value shall be determined by
      a nationally recognized or major regional investment banking firm or firm
      of independent certified public accountants of recognized standing (which
      may be the firm that regularly examines the financial statements of the
      Company) selected in good faith by the Board, and in either case shall be
      described in a statement provided to all registered holders of this
      Series) of the portion of assets or evidences of indebtedness so
      distributed or such subscription rights applicable to one share of Common
      Stock. Such adjustment shall be made whenever any such distribution is
      made and shall become effective immediately after the record date
      mentioned above. No adjustment shall be made pursuant to this subsection
      5(b)(iii) if such evidence of indebtedness or assets are also distributed
      to the holders of this Series on the basis of the number of shares of
      Common Stock then issuable on the conversion of the shares of this Series.

            (iv) No notification to the holders of any adjustment in the
      Conversion Price otherwise required by this Section 5 shall be required
      unless such adjustment would require an increase or decrease of at least
      1% in such price; provided, however, that any adjustment which by reason
      of this 

                                      -7-
<PAGE>
      subsection 5(b)(iv) is not required to be made shall be carried forward
      and taken into account in any subsequent adjustments, and that upon
      presentment of shares of this Series for conversion, all adjustment shall
      be made calculating the conversion rights of such holder. All calculations
      under this Section 5 shall be made to the nearest cent or the nearest
      1/100th of a share, as the case may be.

            (v) Subject to (iv) above, whenever the Conversion Price is
      adjusted, as herein provided, the Company shall promptly mail to each
      registered holder of shares of this Series a notice setting forth the
      Conversion Price after such adjustment and setting forth a brief statement
      of the facts requiring such adjustment. Such notice prepared in good faith
      shall be conclusive evidence of the correctness of such adjustment absent
      manifest error.

            (vi) In case:

                  (A) the Company shall declare a dividend (or any other
            distribution) on the Common Stock payable otherwise than in cash out
            of its earned surplus; or

effective, and the date as of which it is expected that holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for
securities or other property deliverable upon such reclassification,

      (c) In case of any reclassification of the Common Stock, then the holders
of the shares of this Series then outstanding shall have the right thereafter to
convert such shares only into the kind and amount of shares of stock and other
securities and property receivable upon or deemed to be held following such

Company into which such shares of this Series could have been converted
immediately prior to such reclassification. This provision shall similarly apply
to successive reclassifications.

      (d) In case of any consolidation or merger of the Company with or into
another Person in which the Company is not the surviving entity or any

right to receive in exchange therefor the kind and amount of shares of stock and

("Reorganization Consideration") by a holder of the number of shares of the

      (e) In case at any time conditions shall arise by reason of action taken
by the Company, which, in the opinion of the Board of Directors of the Company,
are not adequately covered by the other provisions hereof and which might
materially and adversely affect the rights of the holders of shares of this
Series, the Board of Directors of the Company shall appoint a firm of
independent certified public accountants of recognized standing (which may be
the firm that regularly examines the financial statements of the Company), who
shall give their opinion as to the adjustment, if any (not inconsistent with the
standards established in this Section 5, of the Conversion Price (including, if
necessary, any adjustment as to the securities into which shares of this Series
may thereafter be convertible) which is or would be required to preserve the
rights of the holders of shares of this Series. The Board of Directors of the
Company shall make the adjustment recommended forthwith upon the receipt of such
opinion or the taking of any such action contemplated, as the case may be;
provided, however, that no such adjustment of the Conversion Price shall be made
which in the opinion of the investment banking firm or firm of accountants
giving the aforesaid opinion would result in an increase of the Conversion Price
to more than the Conversion Price then in effect.

      (c) The issuance of certificates for shares of Common Stock on conversion
of this Series shall be made without charge to the holders thereof for any

required to pay any tax that may be payable in respect of any transfer involved
in the issuance and delivery of any such certificate in a name other than that
of the holder of the shares of this Series converted was made and the Company
shall not be required to issue or deliver such certificates unless or until the
Person or Persons requesting the issuance thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the
Company that such tax has been paid.

      (d) The exercise by a holder of shares of this Series of the conversion
rights granted herein is subject in all respects to and conditioned upon
compliance by the parties with the HSR Act, and rules and regulations
promulgated pursuant thereto, to the extent that said act, rules and regulations
are applicable to such exercise. The Company and such holder agree to make such
filings with and provide such information to the Federal Trade Commission and
the Department of Justice with respect to such exercise as are required in
connection with the HSR Act in a timely manner and to join each others request
for early termination. The Company and such holder will use such reasonable
efforts to obtain all governmental approval required to permit such exercise and
to cause early termination of the waiting period under the HSR Act.

Transaction, unless either (A) a majority of the Continuing Directors shall have

                  (c) In connection with the Merger, TMR's Board of Directors

contemplated in the Merger Agreement or the items referenced to in Section
2.3(w), (x), (y) and (z). Further, TMR has no "poison pill" or takeover defense

not amend or modify any of the foregoing actions nor shall TMR implement any
new, additional, amended or modified poison pill or takeover defense mechanism,
unless, in each and every such case, provision shall be made to exclude SLOPI
and its Affiliates from all effects thereof. This Section 2.1(c) shall survive
the termination of this Agreement.

                  (d) TMR and SLOPI agree that the operative provisions, as
presently in effect, of Article Eight of TMR's Articles of Incorporation and
Part Thirteen of the TBCA will apply to any business combination transaction

            2.2   TMR BOARD OF DIRECTORS.

                  (a) Subject to restrictions of applicable law and unless this
Agreement has been terminated, on the Director Election Date (defined below),
TMR shall appoint SLOPI Designee(s) (defined below) to fill the vacancies
created by the removal of the Preferred Director(s) in accordance with the
Certificate of Designation for the Preferred Stock, to serve until their
successors are elected or their earlier resignation or removal.

                  (b) From and after the date on which all the Preferred Shares
shall have been converted into Common Stock (the "Director Election Date") and
until the earlier of (i) termination of this Agreement or (ii) SLOPI and its
Affiliates shall Beneficially Own Shares constituting less than 21% of the then
outstanding shares of Common Stock, then, in connection with each election of
directors of TMR, whether at an annual or special meeting, TMR will nominate,
and, subject to the fiduciary obligations of the TMR directors, solicit proxies
for, in accordance with its procedures 

                                      -7-
<PAGE>
for the nomination of, and solicitation of proxies for, management-slate
directors, a number of persons designated by SLOPI (all such persons who, at any
time, are or were designated by SLOPI for purposes of this Agreement are
referred to herein as the "SLOPI Designee(s)") such that, after giving effect to
the election of such persons to the Board of Directors of TMR, the number of
SLOPI Designees then serving on the Board of Directors of TMR shall equal the
product (rounded downward to the nearest whole number, but, in any event, not
less than one) of (i) the total number of directors constituting the entire
Board of Directors of TMR multiplied by (ii) 20% (the "Director Percentage").

                  (c) If at any time the number of directors constituting the
Board of Directors of TMR shall decrease so that SLOPI would be entitled to
designate fewer directors than are then serving as SLOPI Designees, SLOPI shall
cause one or more of the SLOPI Designees serving as TMR directors to resign so
that the percentage of the Board of Directors consisting of SLOPI Designees does
not exceed the Director Percentage (rounded downward to the nearest whole
number, but, in any event, not less than one); provided, that in no event will
there ever be less than one SLOPI Designee. Further, upon termination of this
Agreement in accordance with its terms, SLOPI shall cause all SLOPI Designees
then serving as directors of TMR to resign immediately.

                  (d) (i) In the event that any SLOPI Designee shall cease to
serve as a director for any reason (other than as set forth in Section 2.2(c)),
the vacancy resulting thereby shall be filled by the remaining directors of the
Company in accordance with its Articles of Incorporation, by-laws and applicable
law by a new SLOPI Designee and such new SLOPI Designee shall thereafter serve
until the expiration of the term of the SLOPI Designee replaced by such new
SLOPI Designee.

                      (ii)  Subject to the provisions of Section 2.2(e), if, 
after the Director Election Date, there shall exist at any time any vacancy or
vacancies on the Board of Directors of TMR as a result of any increase in the
number of directors that constitutes the entire Board of Directors of TMR, which
the directors of TMR then in office intend to fill in accordance with TMR's
Articles of Incorporation, by-laws and applicable law, SLOPI shall be entitled
to designate one or more persons as SLOPI Designees to fill such vacancy or
vacancies if and to the extent necessary so that, after giving effect to the
filling of such vacancy or vacancies, the number of SLOPI Designees then serving
on the Board of Directors of TMR shall equal the Director Percentage (rounded
downward to the nearest whole number, but, in any event, not less than one). TMR
agrees to take all actions appropriate or necessary to ensure that any SLOPI
Designees designated pursuant to the preceding sentence are appointed to the
Board of Directors of TMR to fill any such vacancy or vacancies filled by the
Board of Directors of TMR as provided in the preceding sentence.

                  (e) Notwithstanding anything to the contrary contained herein,
no SLOPI Designee may be a person who previously has been a director of TMR and
was properly removed for cause from the Board of Directors of TMR or a person
who has been convicted of a felony or a crime involving moral turpitude.

<PAGE>
                  (f) The SLOPI Designees will be furnished with all information
that is provided to all other directors of TMR (in their capacities as such) at
the same time as such information is furnished to such other directors (in their
capacities as such).

                  (g) SLOPI shall cause all SLOPI Designees serving as directors
of TMR to comply with the retirement policies of TMR as in effect on the date
hereof or as hereafter amended or modified from time to time by the Board of
Directors of TMR or its shareholders; provided that no such amendment or
modification to such policies shall be binding upon SLOPI or the SLOPI Designees
unless at least one SLOPI Designee shall have voted in favor of such amendment
or modification at the meeting, or in the action in lieu of a meeting, of the
Board of Directors of TMR at or in which it is considered.

                  (h) At all times when there is a SLOPI Designee on TMR's Board
of Directors, at least one SLOPI Designee shall be a member of each Audit
Committee of the Board of Directors. Each SLOPI Designee who is a member of the
Audit Committee shall have unrestricted access to TMR's independent accountants
and all audit and tax work papers to the same extent as any other member of the
Audit Committee.

            2.3 LIMITATION ON ACQUISITION OF ADDITIONAL SHARES BY SLOPI. From
and after the date hereof, SLOPI shall not acquire any shares of Common Stock,
other than the Common Shares and the Preferred Shares owned by SLOPI as of the
Effective Time and after giving effect to the Closing, (i) without the prior
written consent of a majority of the Continuing Directors or (ii) unless (A) the
third anniversary of the date of this Agreement shall have occurred and (B) at
the time of such acquisition no SLOPI Designee(s) or Preferred Director(s) shall
be serving on the Board of Directors of TMR or SLOPI and its Affiliates would
collectively Beneficially Own less than 21% of the then outstanding Common
Stock; provided, however, that nothing in this Section 2.3 shall limit SLOPI's
power and right (w) to convert shares of Preferred Stock into shares of Common
Stock, or (x) to purchase or acquire shares as a result of any stock dividend or
stock split, reclassification of the Common Stock, or the exercise or conversion
of any security received by SLOPI from TMR in respect of its Shares, or (y) to
receive shares of Common Stock pursuant to Section 2.7 to make up a Deficiency
Amount or (z) to acquire shares of Common Stock or any TMR Exchangeable Security
pursuant to Section 2.6 or to convert, exchange or exercise any such TMR
Exchangeable Security.

            2.4 RESTRICTIONS ON TRANSFER. From and after the date hereof until
the termination of this Agreement, SLOPI and its Affiliates shall not sell,
transfer or otherwise convey (when used as a verb, "Transfer" and, any sale,
transfer or other conveyance, a "Transfer") Beneficial Ownership of any Shares
(including Shares subject to Exchangeable Securities), without the prior written
consent of a majority of the Continuing Directors, which consent shall not be
unreasonably withheld, except that, in any event, any and all of the following
Transfers shall be permitted:

                                      -9-
<PAGE>
                  (a) One or more Transfers to Shell or a direct or indirect
Affiliate of Shell, provided that Shell and each such Affiliate of Shell agrees
in writing with TMR to be bound by the same restrictions as are applicable to
SLOPI hereunder.

                  (b) One or more Transfers to TMR or a to a direct or indirect
Subsidiary of TMR (pursuant to a tender offer or otherwise).

                  (c) One or more Transfers pursuant to a merger, consolidation
or compulsory share exchange, in which TMR is a constituent corporation.

                  (d) One or more Transfers made as a pro rata dividend or
distribution to the holders of the common stock of SLOPI or its Affiliates,
provided, unless such dividend or distribution is to the public shareholders of
any of the Royal Dutch/Shell Group of Companies, such holders agree in writing
with TMR to be bound by the same restrictions as SLOPI hereunder.

                  (e) One or more Transfers to any Person (other than SLOPI or
any Affiliate of Shell) who shall have commenced a tender or exchange offer for
shares of Common Stock if, at the time of public announcement of the tender or
exchange offer: (i) SLOPI and its Affiliates collectively Beneficially Own less
than 21% of the then outstanding shares of Common Stock and no SLOPI Designee or
Preferred Director is serving on the TMR Board of Directors, or (ii) SLOPI and
its Affiliates collectively Beneficially Own more than 21% of the then
outstanding shares of Common Stock or any SLOPI Designee or Preferred Director
is serving on the TMR Board of Directors, unless SLOPI and any Affiliates first
provide to TMR a preferential right to purchase, for cash, all such shares which
SLOPI and any Affiliates would be willing to tender or exchange at a price of
105% of the tender offer price which SLOPI and any Affiliates would be willing
to accept (which shall be the market value of the security to be exchanged on
such date if publicly traded or the cash equivalent value as reasonably
determined in good faith by SLOPI and its Affiliates). With respect to clause
(ii) above, SLOPI and its Affiliates shall give TMR notice of its willingness to
accept the tender or exchange offer at least 10 calendar days prior to its then
stated expiration date and, if TMR desires to exercise its preferential purchase
right, it must so notify SLOPI and its Affiliates in writing within said 10
calendar day period. Once TMR has given notice to SLOPI and its Affiliates that
TMR will exercise such preferential right, then, on such then stated expiration
date of the tender or exchange offer, TMR will be obligated to close the
purchase and pay in full in cash, and SLOPI and its Affiliates will be obligated
to sell, at the applicable 105% price notwithstanding anything that may
otherwise occur with respect to the tender or exchange offer, including, without
limitation, withdrawal, extension, modification, or increase or decrease in the
tender or exchange price or other consideration. Once TMR has not exercised a
preferential right to purchase with respect to a particular tender or exchange
offer made by a particular Person, then SLOPI and its Affiliates shall not
thereafter be required to make any additional preferential purchase rights
available to TMR with respect to such particular tender or exchange offer, even
if in such tender or exchange offer there is an extension or modification of or
an increase or decrease in price or other consideration, in any tender or
exchange offer made by such particular Person; provided, however, that SLOPI
will 

                                      -10-
<PAGE>
be required to provide to TMR a preferential purchase right with respect to any
tender or exchange offer made by each other Person or with respect to any new
tender or exchange offer by such particular Person which SLOPI and its
Affiliates would be willing to accept.

                  (f) From and after the following anniversaries of the date of
this Agreement, SLOPI and its Affiliates may, collectively, sell the following
percentages of the number of their Common Shares in one or more Public
Offerings, Private Placements and/or transactions described below in paragraphs
(h), (i), or (j):

                                        PERCENTAGE OF
                                        COMMON SHARES

      Third                          25%               50%
      Fourth                         25%               75%
      Fifth                          25%              100%
      --------------------
      *These time restrictions and percentages will also apply to any shares of
      Common Stock acquired by SLOPI and its Affiliates upon conversion of any
      Preferred Shares into Common Shares, which will result in additional
      Common Shares that can be Transferred based on the percentage limitations
      being applied to a greater number of Common Shares.

Notwithstanding the above, if, at any time or from time to time, SLOPI or any of
its Affiliates receive Common Shares pursuant to Section 2.7 to make up a
Deficiency Amount, then immediately the same number of Common Shares will be
available for Transfer . Such increased availability for Transfer and any actual
Transfer(s) will not reduce or delay other Transfers otherwise permitted to be
made in accordance with the foregoing.

                  (g) From and after the following anniversaries of the date of
this Agreement, SLOPI may sell the following percentages of the number of its
Preferred Shares in one or more Private Placements:

                  (h) Subject to paragraphs (f) and (g), as such may be modified
pursuant to paragraph (k) below, one or more Transfers in accordance with Rule
144 or Rule 145.

                  (i) Subject to paragraphs (f) and (g) as such may be modified
pursuant to paragraph (k) below, one or more Transfers of Shares in a Public
Offering or in a public offering (other than a Public Offering) made pursuant to
a registration statement which has been declared effective by the SEC under the
Securities Act (any such Public Offering or public offering, a "Registered
Transaction"); provided, however, that, in connection with any such Registered
Transaction, SLOPI and the Company shall obtain from the managing underwriter of
such Public Offering or from each broker through which such public offering is
made, as the case may be, a commitment to use its reasonable best efforts to
make a broad public distribution of the Shares (including an indirect
distribution of Shares as a result of a distribution of Exchangeable Securities)
to be Transferred in such Registered Transaction. The managing underwriter or
broker, as the case may be, will be advised that, for purposes of this
Agreement, a "broad public distribution" means a distribution such that no
Person is allocated for purchase in such Registered Transaction a number of
Shares in excess of (A) 5% of the then outstanding shares of Common Stock (after
giving effect to the offering of the Common Shares and any other securities
being offered by TMR concurrently therewith in such Registered Offering) or (B)
in the case of a Public Offering, in excess of 20% of the number of shares of
Common Shares being offered in such Public Offering, provided that, in the case
of this clause (B), there shall be disregarded Common Shares allocated for
purchase by a mutual fund, a pension fund, an investment adviser (which
investment adviser shall be registered under the Investment Advisers Act of
1940, as amended) for any mutual fund or pension fund, or any party who is
entitled to report such party's holdings of Common Stock on Schedule 13G
promulgated under the Exchange Act in light of that party's investment intent.

                  (j) Notwithstanding paragraphs (f) or (g), as such may be
modified pursuant to paragraph (k) below, such numbers of shares of Common Stock
as are equal to the numbers of shares that SLOPI and its Affiliates may from
time to time have received pursuant to Section 2.7 to make up a Deficiency
Amount.

                  (k) Notwithstanding paragraphs (f) and (g) above, if (i) TMR
shall ever, in connection with a merger, consolidation, share exchange, or
acquisition of a business or properties or similar transaction, sell or issue or
commit to sell or issue 5,000,000 (as adjusted for stock splits, reverse splits,
reclassifications, and similar actions) or more shares of Common Stock or TMR
Exchangeable Securities that, at the time of issuance, sale or commitment and
assuming full conversion, exchange or exercise thereof, represent 5,000,000 (as
adjusted for stock splits, reverse splits, reclassifications, and similar
actions) or more of the Voting Shares and (ii) at or prior to the meeting of the
TMR Board of Directors approving any such transaction the TMR Board of Directors
shall not have received an opinion letter from an investment banking firm of
national recognition to the effect that the contemplated transaction is fair,
from a financial point of view, to TMR, then (x) SLOPI and its Affiliates will,
immediately or at any time thereafter, be permitted to Transfer an additional
number of Common Shares equal to the number of shares of Common Stock and/or the
Common Stock equivalent of the Voting Shares represented by the transaction as
to which the requisite fairness opinion was not obtained, and (y) if such would
result in earlier or greater Transfers by SLOPI and its Affiliates, the tables
in paragraphs (f) and (g) shall upon the date of issuance, sale or commitment
(the "Relevant Date") be revised to read, in their entirety:

            2.5 VOTING OF COMMON SHARES. During the term of this Agreement and
prior to the conversion of all of the Preferred Shares, the following provisions
will apply: SLOPI and its Affiliates shall be entitled to vote, in its or their
complete discretion, and on all matters, such number of its Common Shares that,
when added to the votes represented by the Preferred Shares, constitute an
aggregate of up to 23% of the then outstanding votes eligible to be cast for
such matter. After the conversion of all the Preferred Shares, SLOPI and its
Affiliates shall be entitled to vote, in its or their complete discretion, and
on all matters, such number of its Common Shares that constitute up to 23% of
the then outstanding votes eligible to be cast for such matter. If only a
portion of the Preferred Shares has been converted, the voting shall be prorated
between the Common Stock and Preferred Stock for a total of up to 23% of the
then outstanding eligible votes to be cast for such matter. With respect to
those Common Shares, if any, that are in excess of the above amounts of the then
outstanding votes eligible to be cast for such matter (the "Excess Shares"),
SLOPI shall vote such Excess Shares pro rata with the votes of all shares, other
than the Excess Shares, that are actually voted for, against or abstain from
voting on each matter. Notwithstanding the previous sentence, SLOPI shall have
complete discretion in voting all of its Common Shares and Preferred Shares on
any matter (i) that constitutes a Business Combination Transaction, (ii) that
would involve a change of control of TMR (for purposes of this section a change
in control shall mean the acquisition by a Person other than SLOPI or its
Affiliates of Beneficial Ownership of more than 50% of the then outstanding
shares of Common Stock), or (iii) with respect to which a vote is taken when any
of the following shall have occurred or shall exist: (w) the Average Per Share
Market Value for TMR's Common Stock with respect to the day in which the matter
is voted upon has been less than $5.50 per share (such amount to be
appropriately adjusted to give effect to stock splits, reverse splits, stock
dividends, reclassifications, share exchanges, dividends and distributions for
which adjustments to the conversion price of the Preferred Shares may be made),
(x) there are any accrued but unpaid dividends on any Preferred Shares, (y) TMR
shall have failed to issue the additional shares of Common Stock required to be
issued pursuant to Section 2.7, or (z) there shall be a continuing and uncured
default by TMR of any of its material obligations under this Agreement, the
Certificate of Designation or Registration Rights Agreement (both as defined in
the Merger Agreement) or the Merger Agreement. The 

                                      -14-
<PAGE>
foregoing does not limit or restrict SLOPI's or its Affiliates' complete
discretion in voting its or their Preferred Shares.

            2.6 RIGHT TO PARTICIPATE IN CERTAIN ISSUANCES BY TMR.

                  (a) If, when, and for so long as, SLOPI and its Affiliates
Beneficially Own shares of Common Stock that would constitute, after giving
effect to the proposed transaction (but not prior to the proposed transaction),
less than the Applicable Percentage of the then outstanding shares of Common
Stock, TMR shall not issue any shares of Common Stock or any Exchangeable
Securities, for any consideration or in any type of transaction, unless TMR
shall have first complied with, in the case of an issuance other than pursuant
to Public Offering, the provisions of Section 2.6(b) or, in the case of a Public
Offering, the provisions of Section 2.6(c).

                  (b) If TMR determines to issue any shares of Common Stock or
any Exchangeable Security, other than in a Public Offering, then TMR shall
provide written notice of such determination to SLOPI, which notice shall
include all the terms of such issuance and shall offer to SLOPI the right to
purchase, at the same price and on the same terms as TMR proposes to issue such
shares of Common Stock or Exchangeable Security to others (or, if TMR proposes
to issue such shares of Common Stock or any Exchangeable Security other than for
cash, at a cash price equal to the current market price of the Common Stock or
if a Exchangeable Security, such value to be determined by agreement between TMR
or SLOPI, or if the parties are unable to agree, by an investment banking firm
or other asset valuation firm of national reputation selected by SLOPI from
Schedule I attached hereto (as such Schedule I may be amended in writing from
time to time by both TMR and SLOPI) with the consent of a majority of the
Continuing Directors, which consent shall not be unreasonably withheld, the cost
of which shall be borne by TMR) a number or amount of the shares of Common Stock
or Exchangeable Securities proposed to be issued that represents the right to
acquire upon exercise, exchange or conversion of such Exchangeable Securities a
number of Voting Shares so that, upon closing of the transaction, SLOPI and its
Affiliates will Beneficially Own the Applicable Percentage of the then to be
outstanding Common Stock (the "Offer Notice"). If SLOPI determines to accept the
offer contained in the Offer Notice, SLOPI shall deliver a written notice to TMR
indicating its acceptance within 10 days after its receipt of the Offer Notice,
which notice shall indicate whether SLOPI has accepted such offer in whole or in
part, and, if accepted in part, the number or amount of shares of Common Stock
or Exchangeable Securities as to which such offer has been accepted (an
"Acceptance Notice"). Any acceptance of the offer contained in an Offer Notice
by delivery of an Acceptance Notice shall be irrevocable and shall constitute a
commitment by SLOPI to purchase from TMR, and by TMR to sell to SLOPI, the
number or amount of shares of Common Stock or Exchangeable Securities covered by
such Acceptance Notice upon the terms contained in the Offer Notice.

                  (c) If at any time and from time to time, (i) TMR determines
to issue any shares of Common Stock or any Exchangeable Security in a Public
Offering, and (ii) as a result thereof SLOPI and its Affiliates would
Beneficially Own less than 

                                      -15-
<PAGE>
the Applicable Percentage of the then to be outstanding shares of Common Stock,
then (y) TMR shall provide written notice of such determination to SLOPI, which
notice shall include the proposed size and other terms of such issuance, to the
extent then known, the name or names of any managing underwriter or placement
agent(s) and the date when it is proposed that any such issuance will be made,
and (z) TMR shall either sell directly or cause the underwriters or placement
agent(s) to offer to SLOPI the right to purchase from TMR directly or from the
underwriters or placement agent(s), at the applicable offering price, a number
or amount of the shares of Common Stock, Exchangeable Securities or other
securities proposed to be issued that, if purchased by SLOPI, would permit SLOPI
and its Affiliates to Beneficially Own a number of shares of Common Stock equal
to Applicable Percentage of the then to be outstanding Common Stock after
closing the proposed issuance.

            2.7   TMR SUPPORT OF CERTAIN STOCK SALES.

            (a) In the event that, from time to time, SLOPI and/or any Affiliate
of SLOPI or of Shell shall sell any of the Common Shares to be issued upon
conversion of Preferred Shares and the net proceeds (after reasonable and
customary commissions, underwriters discounts, placement fees and expenses of
sale, excluding expenses of legal counsel for the selling shareholder(s))
received by SLOPI or such Affiliate for such Common Shares shall result in a
Deficiency Amount, then TMR shall, at its option, (i) pay to SLOPI an amount of
cash equal to the Deficiency Amount or (ii) issue to SLOPI or such Affiliate
additional fully paid and non-assessable shares of Common Stock equal in value
to the Deficiency Amount. All shares of Common Stock issued by TMR in respect of
a Deficiency Amount (i) shall be valued in the manner set forth in the
definition of Deficiency Amount and (ii) shall be issued as of the closing of
such sale. If TMR issues shares of Common Stock in respect of a Deficiency
Amount, then TMR will cause such shares to be listed for trading on the
principal stock exchange for the Common Stock.

                  (b) In the event, (i) SLOPI shall propose to Transfer Shares
to a person who has committed to purchase such Shares pursuant to a transaction
not involving a Public Offering at a time when SLOPI is authorized to sell such
Shares, (ii) under the terms of this Agreement, such person would be required to
enter into an agreement with TMR and such person and TMR are unable to effect
such agreement, and (iii) SLOPI shall subsequently sell such Shares pursuant to
a Public Offering, TMR shall pay the reasonable and customary commissions,
underwriters discounts and expenses of sale payable by SLOPI in such sale,
excluding expenses of legal counsel for SLOPI. If this Section 2.7(b) shall be
applicable in the circumstances, then this Section shall control over Section
2.C (11) g of the Registration Rights Agreement.

      LOUISIANA ONSHORE PROPERTIES, INC. DATED AS OF JUNE 30, 1998. A COPY OF

                  (b) All certificates representing Shares shall, subject to

      EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR PURSUANT TO RULE 144
      UNDER THE ACT, UNLESS THE COMPANY SHALL HAVE BEEN FURNISHED WITH AN
      OPINION OF COUNSEL, WHICH OPINION SHALL BE REASONABLY SATISFACTORY TO
      COUNSEL FOR TMR ENERGY CORPORATION, THAT REGISTRATION UNDER THE ACT IS NOT
      REQUIRED."

                  (c) After such time as either of the legends set forth in
Sections 3.1(a) and (b) is no longer required hereunder (including without
limitation as a result of the termination of this Agreement in accordance with
its terms) or if the securities represented by a certificate have been
registered under the Securities Act pursuant to an effective registration
statement or are to be sold pursuant to Rule 144, or if the Company shall have
been furnished with an opinion of counsel, which opinion shall be reasonably
satisfactory to counsel for TMR, that registration under the Securities Act is
not required, as the case may be, then, in any such event, upon the request of
SLOPI, TMR shall cause such certificate or certificates to be exchanged for a
certificate or certificates that do not bear any legend.

            3.2 IMPROPER TRANSFER. Any attempt by SLOPI or its Affiliates to
Transfer any Shares other than in accordance with this Agreement shall be null
and void and neither TMR nor any transfer agent for such securities shall be
required to give any effect to such attempted Transfer in its stock records.

unless such plan exempts SLOPI and its Affiliates from all effects thereof.

            4.6 LIMITATION ON REDUCTIONS OF PUBLIC FLOAT BY TMR. TMR shall not
take any action, including without limitation an acquisition by TMR or any of
its Affiliates of shares of Common Stock then outstanding, or a recapitalization

<PAGE>
hereof. Except for the permitted Transfers to Shell and Affiliates of Shell or

such transaction this Agreement will be continued in effect by TMR or any

request from Security Holder requesting that the Company file a Registration
Statement relating to Registrable Securities, the Company will as promptly as
practicable prepare and file a Registration Statement and use reasonable best
efforts to cause the Registration Statement to become effective; subject,
however, to the following provisions:

            (1) the Company shall be required to file no more than an aggregate
of 5 Registration Statements on behalf of Security Holder (or Security Holders
in the event of an assignment of this Agreement) pursuant to this Subsection
2.A, plus 

                                      -2-
<PAGE>
any number of additional Registration Statements (not to exceed an aggregate of
an additional 5) as to which, at the time of the first filing with the SEC, the
Security Holder (or Security Holders in the event of an assignment of this
Agreement) and its underwriter(s) have reasonably estimated that the price to
the public of the Registrable Securities to be sold (before discounts,
commissions, and expenses) will be equal to or greater than $50,000,000;

            (2) the Company shall not be obligated (i) to file a requested
Registration in the event that the aggregate number of Registrable Securities to
be included in such requested Registration is less than 2 1/2% of the issued and
outstanding Common Stock; or (ii) to prepare or file such Registration Statement
or an amendment or supplement thereto, and may suspend sales, at any time when
the Company reasonably determines (by action of the Company's Board of Directors
or an officer duly authorized by the Board of Directors to make such decision)
that the filing thereof at the time requested, or the offering of Registrable
Securities pursuant thereto, would materially and adversely affect a pending or
proposed offering of securities of the Company, an acquisition, merger,
recapitalization, consolidation, reorganization or similar transaction relating
to the Company or negotiations, discussions or pending proposals with respect
thereto or require premature disclosure of information not otherwise required to
be disclosed to the potential detriment of the Company; PROVIDED, HOWEVER, that
such period of sale or distribution shall resume after any such suspension for a
number of days necessary to keep such Registration effective for permitted sales
thereunder for a term of 90 days. The filing of a Registration Statement, or any
amendment or supplement thereto, by the Company may not be deferred, and the
sale and distribution of shares may not be suspended, in each case pursuant to
the foregoing provisions, for more than 60 days after the abandonment or
consummation (or the completion of the distribution of securities in the case of
a public offering) of any of the proposals or transactions described therein or,
in any event, for more than 120 days during any one year;

            (3) a Registration Statement filed pursuant to a request of Security
Holder shall first include all Registrable Securities requested to be included
by Security Holder and, only after such inclusion, may, include securities of
the Company being sold for the account of the Company provided, however, that
securities to be offered on behalf of the Company will be included in such
Registration Statement only to the extent that, in the reasonable opinion of the
managing underwriter for the Public Offering of Registrable Securities on behalf
of Security Holder, such inclusion will not materially adversely affect the
distribution of Registrable Securities on behalf of Security Holder;

            (4) the selection of an underwriter for a Public Offering of
Registrable Securities by Security Holder shall be subject to the approval of
the Company, which shall not be unreasonably withheld;

            (5) for purposes of paragraph (1) of this Subsection A, if a
requested Registration Statement is filed and the Company otherwise complies
with its obligations hereunder, but the Registration Statement is withdrawn by
Security Holder due to a 

                                      -3-
<PAGE>
delay in the offering requested by the Company for a period of more than 15
business days pursuant to Section 2, then no requested Registration Statement
shall be deemed to have been filed; and

            (6) no Other Holder (as defined below) shall be entitled to include
securities or piggyback in any Registration demanded by Security Holder.

      B. INCIDENTAL/"PIGGY-BACK" REGISTRATIONS. If the Company at any time
proposes to file a Registration Statement (other than a Registration Statement
filed pursuant to Subsection A of this Section) under the Securities Act
relating to a Public Offering of Common Stock to be sold for cash that would
permit the registration of Registrable Securities, it will give Security Holder
as much advance notice, in writing, as is reasonably practicable under the
circumstances, but in any event not less than 5 days, before the filing with the
Commission of such Registration Statement, which notice shall set forth the
securities proposed to be registered. The notice shall offer to include in such
filing such amount of Registrable Securities as Security Holder may request. If
Security Holder wishes to have Registrable Securities registered for sale in the
Public Offering pursuant to this Subsection B, it shall advise the Company in
writing within 20 days after the date of receipt of such offer from the Company
(or such shorter period, but in any event not less than 5 days, as the Company
shall specify in its notice to Security Holder), setting forth the amount of
Registrable Securities for which registration is requested. If the managing
underwriter of the proposed Public Offering of Common Stock by the Company shall
advise the Company in writing that, in the reasonable opinion of the managing
underwriter, the distribution of the Registrable Securities requested by
Security Holder to be included in the Registration Statement concurrently with
securities being registered for sale by the Company would materially adversely
affect the distribution of such securities by the Company and Security Holder,
then the Company shall so advise the Security Holder and the number of
securities that are entitled to be included in the registration and underwriting
shall be allocated as follows: (i) in the event a Registration Statement is
being filed in connection with the exercise of registration rights by a security
holder other than the Security Holder (an "Other Holder"), all of any Other
Holder's shares of Common Stock shall be included in the registration and the
remaining number of securities that are entitled to be included in the
registration shall be allocated (A) 80% to the Company and any other
shareholders (not including the Other Holder or the Security Holder) whose
shares are to be included in such Registration Statement and (B) 20% to the
Security Holder, and (ii) in the event the registration is not being filed in
connection with the exercise of registration rights of any Other Holder (a) 80%
to the Company and any other shareholders (not including Security Holder) whose
shares are to be included in such Registration Statement and (b) 20% to Security
Holder. If any Person does not agree to the terms of any such underwriting, such
Person shall be excluded therefrom by written notice from the Company or the
underwriter.

            Nothing contained in this Subsection B shall, however, limit the
Company's right to cancel, postpone or withdraw any such registration proposed
by the Company for any reason.

                                      -4-
<PAGE>
            Any obligation of the Company to effect a registration pursuant to
this Subsection B shall be conditioned upon Security Holder entering into an
underwriting agreement with the Company and the managing underwriters of the
registered offering of the type described in paragraph (10) of Subsection C.

      C. REGISTRATION PROCEDURES. If the Company is required by the provisions
of Subsections A or B of this Section 2 to effect the Registration of any of the
Registrable Securities under the Securities Act, the Company will, as soon as in
reasonably practicable:

            (1) Prepare and file with the Commission a Registration Statement
with respect to such securities and use its reasonable best efforts to cause
such Registration Statement to become and, subject to paragraph (2) of this
Subsection C, remain effective.

            (2) Keep such Registration effective, and the prospectus used in
connection therewith, current for a period of ninety (90) days or until the
Security Holder has completed the distribution described in the Registration
Statement relating thereto, whichever first occurs (the "Selling Period");
provided, however, that (a) the Selling Period shall be extended for a period of
time equal to any period that Security Holder refrains from selling any
securities included in such registration pursuant to a suspension under
Subsection A.

            (3) 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 and
such prospectus current in compliance with Section 10 of the Securities Act, and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all Common Stock covered by such Registration Statement;
provided, however, that the Company shall have no obligation under this
paragraph (3) after the period required by paragraph (2) of this Subsection C
has lapsed.

            (4) Furnish to Security Holder such number of copies of such
Registration Statement and of each amendment and supplement thereto (in each
case including all exhibits), such number of copies of the prospectus included
in such Registration Statement (including each preliminary prospectus, summary
prospectus and prospectus supplement), in conformity with the requirements of
the Securities Act, and such other documents, as Security Holder may reasonably
require in order to facilitate the public offering, sale or other disposition of
the Registrable Securities owned by Security Holder.

            (5) Use reasonable best efforts to register or qualify the Common
Stock covered by such Registration Statement under such other securities or blue
sky laws of jurisdictions in the United States of America as Security Holder
shall reasonably request (excluding however any jurisdiction in which the filing
would subject the Company to additional tax liability, and any jurisdiction in
which the Company would be required to execute a general consent to service of
process in effecting such 

                                      -5-
<PAGE>
registration or qualification which consent would not be required but for this
paragraph (5)), and do such other acts and things as may be required to enable
Security Holder to consummate the public sale or other disposition in such
jurisdictions of the Registrable Securities owned by Security Holder.

            (6) Otherwise use reasonable 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 which
satisfies the provisions of Section 11(a) of the Securities Act.

            (7) Immediately notify Security Holder at any time when a prospectus
is required to be delivered under the Securities Act within the Selling Period
referred to in paragraph (2) of this Subsection C, of the Company becoming aware
that the prospectus included in the Registration Statement, or as such
prospectus may be amended or supplemented, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary in order to make the statements therein not misleading in light of
the circumstances then existing, and at the request of Security Holder to
promptly prepare and furnish to Security Holder a number of copies of an amended
or supplemental prospectus as may be necessary so that, as thereafter delivered
to the purchasers of such Registrable Securities, such prospectus shall not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein not misleading in the light of the circumstances then existing. In the
event the Company shall give any such notice, Security Holder shall immediately
suspend use of the prospectus and the Selling Period shall be extended by the
number of days during the period from and including the date of the giving of
such notice to and including the date when Security Holder shall have received
the copies of such supplemented or amended prospectus.

            (8) In the event that the Company suspends use by Security Holder of
a prospectus relating to an offering of Registrable Securities pursuant to a
suspension under Subsection A, because the Company is conducting negotiations
for a material business combination or due to pending material developments or
events that have not yet been publicly disclosed and as to which the Company
believes public disclosure will be prejudicial to the Company, the Company shall
deliver notice in writing to the effect of the foregoing and, upon receipt of
such notice, the Security Holder shall not use the prospectus, and the Selling
Period shall cease to run or will not commence, until such Security Holder has
received copies of the supplemented or amended prospectus provided for in
paragraph 3 of this Subsection C, or until it is advised in writing by the
Company that the prospectus may be used, and has received copies of any
additional or supplemental filings that are incorporated or deemed incorporated
by reference in such prospectus. The Company will use reasonable best efforts to
ensure that the use of the prospectus may be resumed, and the Selling Period
will commence, as promptly as is practicable and, in any event, promptly after
the earlier of (x) public disclosure of such material business combination or
pending material development or event sufficient to permit an affiliate of the
Company to sell Common Stock or (y) in the judgment of 

                                      -6-
<PAGE>
the Company, public disclosure of such material business combination or material
development or event would not be prejudicial to the Company.

            (9) Use its reasonable best efforts to list such Registrable
Securities on the primary securities exchange or other trading market on which
the Common Stock is then listed, if such Registrable Securities are not already
so listed and if such listing is then permitted under the rules of such exchange
or other trading market, and to provide a transfer agent and registrar for such
Registrable Securities covered by such Registration Statement not later than the
effective date of such Registration Statement.

            (10) Enter into such agreements (including an underwriting agreement
in customary form and containing customary provisions relating to legal opinions
and accountants' letters and customary representations and warranties and
customary provisions for mutual indemnification and contribution between the
Company and the underwriters for Security Holder) and take such other actions as
Security Holder may reasonably request in order to expedite or facilitate the
disposition of such Registrable Securities.

            (11) Make available for inspection by Security Holder, by any
underwriter participating in any disposition to be effected pursuant to such
Registration Statement and by any attorney, accountant or other agent retained
by Security Holder or any such underwriter, all customary financial and other
records, customary corporate documents and properties of the Company, and cause
all of the Company's officers, directors and employees to supply all customary
information requested by Security Holder, such underwriter, attorney, accountant
or agent, as is reasonably needed in connection with such Registration
Statement; provided such parties execute confidentiality agreements reasonably
acceptable to the Company.

            Except as otherwise provided in Section 2.7(b) of the Stock Rights
and Restriction Agreement, underwriting discounts and commissions attributable
to securities offered on behalf of Security Holder plus the fees and expenses of
separate counsel for Security Holder incurred in connection with effecting a
Registration pursuant to this Section 2 shall be borne by Security Holder. All
other expenses incurred in connection with the Registration Statement shall be
borne by the Company.

            It shall be a condition precedent to the obligation of the Company
to take any action pursuant to this Section 2 in respect of the Registrable
Securities which are to be registered at the request of Security Holder that
Security Holder shall furnish to the Company such information regarding the
securities held by it and the intended method of disposition thereof as the
Company shall reasonably request and as shall be required in connection with the
action taken by the Company.

      D.    INDEMNIFICATION.

            (1) In the event of any Registration of any Registrable Securities
under the Securities Act pursuant to this Section 2, the Company agrees to
indemnify and hold harmless Security Holder, its directors, officers and
employees, and each other 

                                      -7-
<PAGE>
Person, if any, who controls Security Holder within the meaning of Section 15 of
the Securities Act, against any losses, claims, damages or liabilities, joint or
several, to which Security Holder or any such director, officer, employee 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 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, 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, and shall reimburse Security Holder or
such director, officer, employee or controlling Person for reasonable legal or
any other expenses reasonably incurred by Security Holder or such director,
officer, employee 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 in writing
for use therein; and provided, further, that the Company shall not be liable in
any such case to the extent that any such loss, claim, damage, liability or
expense arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission in the prospectus if such untrue
statement or alleged untrue statement or omission or alleged omission has been
the subject of a notice given to Security Holder pursuant to paragraph (7) of
Subsection C if Security Holder after receipt of such notice and prior to the
receipt of a corrected prospectus sold a Registrable Security to the Person
asserting such loss, claim, damage, liability or expense who purchased such
Registrable Security which is the subject thereof form Security Holder. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of Security Holder or such director, officer, employee or
participating Person or controlling Person, and shall survive the transfer of
such securities by Security Holder.

            (2) Security Holder agrees to indemnify and hold harmless the
Company, its directors, officers and employees 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, officer, or
employee 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 Registrable Securities
were registered under the Securities Act at the request of Security Holder, 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 made in such Registration
Statement, 

                                      -8-
<PAGE>
preliminary prospectus, prospectus, amendment or supplement in reliance upon and
in conformity with written information furnished to the Company in writing by
Security Holder for use therein, and shall reimburse the Company or such
director, officer, employee or other Person for any reasonable legal or any
other expenses reasonably incurred in connection with investigating or defending
any such loss, claim, damage, liability or action.

            (3) Promptly after receipt by an indemnified party hereunder of
written notice of the commencement of any action or proceeding involving a claim
referred to in the preceding paragraphs of this Subsection E, such indemnified
party will, if a claim in respect thereof is to be made against an indemnifying
party, give written notice to the latter of the commencement of such action;
provided, that the failure of any indemnified party to give notice as provided
herein shall not relieve the indemnifying party of its obligation under this
Subsection D to the extent the indemnifying party is not materially prejudiced
by such failure. In case any such action is brought against an indemnified
party, the indemnified party shall permit the indemnifying party to assume the
defense of such action or proceeding, provided that counsel for the indemnifying
party, who shall conduct the defense of such action or proceeding shall be
approved by the indemnified party (whose approval shall not be unreasonably
withheld) and the indemnified party may participate in such defense at such
indemnified party's expense unless in the opinion of counsel to such indemnified
party a conflict of interest between such indemnified and indemnifying parties
may exist in respect of such claim that would prevent the indemnified party's
counsel from adequately representing both parties, in which event the
indemnifying party shall pay the reasonable fees and expense of separate counsel
for the indemnified party. No indemnifying party will consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect to such claim or litigation. The
indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm for all indemnified parties. The indemnifying party
shall not be liable for any settlement of any proceeding effected without its
written consent.

            (4) Indemnification similar to that specified in the preceding
paragraphs of this Subsection E shall be given by the Company and Security
Holder (with such modifications as shall be appropriate) with respect to
liability related to any required registration or other qualification of
Registrable Securities under any Federal or state law or regulation of
governmental authority other than the Securities Act.

            (5) If the indemnification provided for in this Subsection D is
unavailable or insufficient to hold harmless an indemnified party under
paragraphs (1) or (2) above, then the indemnifying party shall contribute to the
amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities referred to in paragraphs (1) or (2) above, in
such proportion as is appropriate to reflect the relative fault of the Company
on the one hand and Security Holder on the other in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities, as well as any other relevant equity considerations. The relative

                                      -9-
<PAGE>
fault shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or Security Holder and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission. The Company and Security Holder agree that it would not be just and
equitable if contributions pursuant to this paragraph (5) were to be determined
by pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the first sentence of
this paragraph (5). The amount paid by an indemnified party as a result of the
losses, claims, damages or liabilities referred to in the first sentence of this
paragraph (5) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any action or claim (which shall be limited as provided in paragraph (3) above
if the indemnifying party has assumed the defense of any such action in
accordance with the provisions thereof) which is the subject of this paragraph
(5). Notwithstanding the provisions of this paragraph (5), in respect of any
loss, claim, damage or liability based upon any untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact which relates to information other than information supplied by Security
Holder, Security Holder shall not be required to contribute any amount in excess
of the amount by which the total price at which the Registrable Securities
offered by it and distributed to the public were offered to the public exceeds
the amount of any damages which Security Holder has otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation. Promptly after receipt
by an indemnified party under this paragraph (5) of notice of the commencement
of any action against such party in respect of which a claim for contribution
may be made against an indemnifying party under this paragraph (5), such
indemnified party shall notify the indemnifying party in writing of the
commencement thereof if the notice specified in paragraph (3) above has not been
given with respect to such action; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party under this paragraph (5) to the extent such omission is
not prejudicial.

      E. PUBLIC AVAILABILITY OF INFORMATION. The Company shall comply with all
public information reporting requirements of the Commission, to the extent
required from time to time to enable Security Holder to sell Registrable
Securities without Registration under the Securities Act within the limitation
of the exemptions provided by (i) Rule 144 under the Securities Act, as such
Rule may be amended from time to time, or (ii) any similar rule or regulation
hereafter adopted by the Commission. Upon the request of Security Holder, the
Company will deliver to Security Holder a written statement as to whether it has
complied with such requirements.

      F. SUPPLYING INFORMATION. The Company shall cooperate with Security Holder
in supplying such information as may be necessary for Security Holder to
complete and file any information reporting forms presently or hereafter
required by the Commission 

                                      -10-
<PAGE>
as a condition to the availability of an exemption from the Securities Act for
the sale of any Registrable Securities.

      G. SPECIFIC PERFORMANCE. Each party hereto acknowledges and agrees that
each other party hereto would be irreparably harmed and would have no adequate
remedy of law if any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. Accordingly, it
is agreed that, in addition to any other remedies by law or in equity which may
be available, the parties hereto shall be entitled to obtain temporary and
permanent injunctive relief with respect to any breach or threatened breach of,
or otherwise obtain specific performance of the covenants and other agreements
contained in this Agreement.

      Section 3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to Security Holder that (a) the Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Texas and has the corporate power and authority to enter into this
Agreement and to carry out its obligations hereunder, (b) the execution and
delivery of this Agreement by the Company and the consummation by the Company of
the transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of the Company and no other corporate proceedings
on the part of the Company are necessary to authorize this Agreement or any of
the transactions contemplated hereby, and (c) this Agreement has been duly
executed and delivered by the Company and constitutes a valid and binding
obligation of the Company, and, assuming this Agreement constitutes a valid and
binding obligation of Security Holder is enforceable against the Company in
accordance with its terms, subject to applicable bankruptcy, reorganization,

      Section 5. STOCK RIGHTS AND RESTRICTIONS AGREEMENT. This Agreement shall
be in all respects subject to the terms and conditions of the Stock Rights and
Restrictions Agreement between the parties hereto and of even date herewith. As
provided in the next sentence, this Agreement may be assigned by Security
Holder, in whole or in part, in connection with any transfer (one or more) of
Registrable Securities that is permitted under the Stock Rights and Restrictions
Agreement except for transfers (i) in a Public Offering or (ii) pursuant to Rule
144 or Rule 145; provided, however, that any such transferee who is not an
Affiliate of Security Holder must acquire from the Security Holder a number of
Registrable Securities equal to at least 25% of the Eligible Stock then held by
Security Holder and its Affiliates. In order for any such transferee to be
entitled to the benefits of this Agreement and thereby become a "Security
Holder," such transferee must agree to be bound by this Agreement by executing a
counterpart of this Agreement. In the event of an assignment or partial
assignment of this Agreement pursuant to this Section 5, notices and requests to
and from the Company pursuant to this Agreement shall continue to be made only
to and from the Security Holder until such time as Security Holder shall
otherwise advise the Company in writing from time to time that a
transferee-Security Holder(s) will give and receive notices and requests.

      In the event that any such transferee-Security Holder is an E&P Company
(as defined in the Stock Rights and Restriction Agreement), then any underwriter
for such E&P Company shall have customary access to perform its due diligence
obligations with respect to any Registration Statement subject to
confidentiality obligations that prohibit the sharing or disclosure of
information with such E&P Company, and no such E&P Company shall, by virtue of
this Agreement, have access to non-public information of the Company.

      No transfer or assignment of this Agreement shall increase the number of
Registrations which the Company is obligated to make under this Agreement.

      Section 6. NOTICES. All notices and other communications hereunder shall
be in writing and shall be deemed given if delivered personally or transmitted

              SECTION 2. AMOUNT AND TERMS OF REVOLVING COMMITMENTS

               2.1 REVOLVING CREDIT COMMITMENTS. (a) Subject to the terms and
conditions hereof, each Lender severally agrees to make revolving credit loans
("REVOLVING CREDIT LOANS" or "LOANS") to the Borrower from time to time during
the Commitment Period in an aggregate principal amount at any one time
outstanding not to exceed the amount of such Lender's Revolving Credit
Commitment, PROVIDED that no Lender shall make any Revolving Credit Loans if,
after giving effect thereto, the sum of such Lender's Revolving Credit Loans and
Commitment Percentage of Letter of Credit Outstandings (in each case, after
giving effect to the Loans requested to be made and the Letters of Credit
requested to be issued on such date) exceeds the lesser of (i) such Lender's
Revolving Credit Commitment and (ii) such Lender's Commitment Percentage of the
Borrowing Base then in effect. During the Commitment Period, the Borrower may
use the Revolving Credit Commitments by borrowing, prepaying the Revolving
Credit Loans in whole or in part, and reborrowing, all in accordance with the
terms and conditions hereof.

               (b) The Revolving Credit Loans may from time to time be (i)
Eurodollar Loans, (ii) ABR Loans or (iii) a combination thereof, as determined
by the Borrower and notified to the Administrative Agent in accordance with
subsections 2.2 and 4.3, PROVIDED that no Revolving Credit Loan shall be made as
a Eurodollar Loan after the day that is one month prior to the Termination Date.

                                                                              24

               2.2 PROCEDURE FOR REVOLVING CREDIT BORROWING. The Borrower may
borrow under the Revolving Credit Commitments during the Commitment Period on
any Business Day, PROVIDED that the Borrower shall give the Administrative Agent
irrevocable notice (which notice must be received by the Administrative Agent
prior to 10:00 a.m., New York City time, (a) three Business Days prior to the
requested Borrowing Date, if all or any part of the requested Revolving Credit
Loans initially are to be Eurodollar Loans or (b) one Business Day prior to the
requested Borrowing Date, otherwise), specifying (i) the amount to be borrowed,
(ii) the requested Borrowing Date, (iii) whether the borrowing is to be of
Eurodollar Loans, ABR Loans or a combination thereof and (iv) if the borrowing
is to be entirely or partly of Eurodollar Loans, the respective amounts of each
such Type of Loan and the respective lengths of the initial Interest Periods
therefor. Each borrowing under the Revolving Credit Commitments shall be in an
amount equal to (x) in the case of ABR Loans, $5,000,000 or a whole multiple of
$1,000,000 in excess thereof (or, if the then Available Commitments are less
than $5,000,000, such lesser amount) and (y) in the case of Eurodollar Loans,
$5,000,000 or a whole multiple of $1,000,000 in excess thereof. Upon receipt of
any such notice from the Borrower, the Administrative Agent shall promptly
notify each Lender thereof. Each Lender will make the amount of its pro rata
share of each borrowing available to the Administrative Agent for the account of
the Borrower at the office of the Administrative Agent specified in subsection
11.2 prior to 11:00 A.M., New York City time, on the Borrowing Date requested by
the Borrower in funds immediately available to the Administrative Agent. Such
borrowing will then be made available to the Borrower by the Administrative
Agent crediting the account of the Borrower on the books of such office with the
aggregate of the amounts made available to the Administrative Agent by the
Lenders and in like funds as received by the Administrative Agent.

               2.3 REPAYMENT OF LOANS; EVIDENCE OF DEBT. (a) The Borrower hereby
unconditionally promises to pay to the Administrative Agent for the account of
each Lender the then unpaid principal amount of each Loan of such Lender on the
Termination Date (or such earlier date on which the Loans become due and payable
pursuant to Section 9). The Borrower hereby further agrees to pay interest on
the unpaid principal amount of the Loans from time to time outstanding from the
date hereof to but not including the date the Loans are paid in full at the
rates per annum, and on the dates, set forth in subsection 4.1.

               (b) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of the Borrower to such
Lender resulting from each Loan of such Lender from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time under this Agreement.

               (c) The Administrative Agent shall maintain the Register pursuant
to subsection 11.6(d), and a subaccount therein for each Lender, in which shall
be recorded (i) the amount of each Loan made hereunder, the Type thereof and
each Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each
Lender hereunder and (iii) both the amount of any sum received by the
Administrative Agent hereunder from the Borrower and each Lender's share
thereof.

               (d) The entries made in the Register and the accounts of each
Lender maintained pursuant to subsection 2.3(b) shall, to the extent permitted
by applicable
<PAGE>
                                                                              25

law, be PRIMA FACIE evidence of the existence and amounts of the obligations of
the Borrower therein recorded; PROVIDED, HOWEVER, that the failure of the
Administrative Agent or any Lender to maintain the Register or any such account,
or any error therein, shall not in any manner affect the obligation of the
Borrower to repay (with applicable interest) the Loans made to such Borrower by
such Lender in accordance with the terms of this Agreement.

               (e) The Borrower agrees that, upon the request to the
Administrative Agent by any Lender, the Borrower will execute and deliver to
such Lender a promissory note of the Borrower evidencing the Revolving Credit
Loans of such Lender, substantially in the form of Exhibit A with appropriate
insertions as to date and principal amount (a "REVOLVING CREDIT NOTE" or
"NOTE").

                          SECTION 3. LETTERS OF CREDIT

               3.1 THE L/C COMMITMENT. (a) Pursuant to the Existing Credit
Agreement, the Issuing Lenders specified on Schedule 3.1 have issued the letters
of credit described on Schedule 3.1 (the "EXISTING LETTERS OF CREDIT"), which
from and after the Closing Date shall continue to be "Letters of Credit"
hereunder. Subject to the terms and conditions hereof, the Issuing Lender, in
reliance on the agreements of the other Lenders set forth in subsection 3.4(a),
agrees to issue letters of credit (together with the Existing Letters of Credit,
the "LETTERS OF CREDIT") for the account of the Borrower on any Business Day
during the Commitment Period in such form as may be approved from time to time
by the Issuing Lender; PROVIDED that the Issuing Lender shall not issue any
Letter of Credit if, after giving effect to such issuance and after giving
effect to any Loans requested to be made or Letters of Credit requested to be
issued on such date, (i) the Letter of Credit Outstandings would exceed
$15,000,000 or (ii) the sum of the Revolving Credit Loans and Letter of Credit
Outstandings would exceed the lesser of (x) the Revolving Credit Commitments and
(y) the Borrowing Base then in effect. Each Letter of Credit shall (i) be issued
to support obligations of the Borrower or any of its Subsidiaries, contingent or
otherwise, which finance the working capital and business needs of the Borrower
and its Subsidiaries, and (ii) shall expire no later than the earlier of (x) one
year (or such later date agreed to by the Issuing Lender) after the date of
issuance and (y) five Business Days prior to the Termination Date, PROVIDED that
any Letter of Credit with a one-year tenor may provide for the extension thereof
for additional one-year periods (which shall in no event extend beyond the date
referred to in clause (y) above). Each Letter of Credit shall be denominated in
Dollars.

               (b) Each Letter of Credit shall be subject to the Uniform Customs
and, to the extent not inconsistent therewith, the laws of the State of New
York.

               (c) The Issuing Lender shall not at any time be obligated to
issue any Letter of Credit hereunder if such issuance would conflict with, or
cause the Issuing Lender or any Participating Lender to exceed any limits
imposed by, any applicable Requirement of Law.

               3.2 PROCEDURE FOR ISSUANCE OF LETTERS OF CREDIT. The Borrower may
from time to time request that the Issuing Lender issue a Letter of Credit by
delivering to the Issuing Lender and the Administrative Agent at their
respective addresses for notices
<PAGE>
                                                                              26

specified herein a letter of credit application in the Issuing Lender's then
customary form (an "L/C APPLICATION") completed to the satisfaction of the
Issuing Lender, and such other certificates, documents and other papers and
information as may be customary and as the Issuing Lender may reasonably
request. Upon receipt of any L/C Application, the Issuing Lender will process
such L/C Application and the certificates, documents and other papers and
information delivered to it in connection therewith in accordance with its
customary procedures and, upon receipt by the Issuing Lender of confirmation
from the Administrative Agent that issuance of such Letter of Credit will not
contravene subsection 3.1, the Issuing Lender shall promptly issue the Letter of
Credit requested thereby (but in no event shall the Issuing Lender be required
to issue any Letter of Credit earlier than three Business Days after its receipt
of the L/C Application therefor and all such other certificates, documents and
other papers and information relating thereto) by issuing the original of such
Letter of Credit to the beneficiary thereof or as otherwise may be agreed by the
Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of such
Letter of Credit to the Borrower and the Administrative Agent promptly following
the issuance thereof, and, thereafter, the Administrative Agent shall promptly
furnish a copy thereof to the Lenders.

               3.3 FEES, COMMISSIONS AND OTHER CHARGES. (a) The Borrower shall
pay to the Administrative Agent, for the account of (i) the Issuing Lender and
the Participating Lenders, a letter of credit commission with respect to each
Letter of Credit, computed for the period from the date such Letter of Credit is
issued (or in the case of the Existing Letters of Credit, to the extent such
commissions have not already been paid, from the Closing Date) to the date upon
which the next payment is due under this subsection (and, thereafter, from the
date of payment under this subsection to the date upon which the next payment is
due under this subsection) at the rate per annum equal to the Applicable Margin
in effect from time to time for Eurodollar Loans of the daily aggregate amount
available to be drawn under such Letter of Credit during such period, and (ii)
the Issuing Lender, a letter of credit commission with respect to each Letter of
Credit in an amount equal to .125% per annum of the daily aggregate amount
available to be drawn under such Letter of Credit. The letter of credit
commissions payable pursuant to clause (i) and (ii) above shall be payable
quarterly in arrears on the last day of each March, June, September and
December, commencing June 30, 1998, and on the Termination Date.

               (b) In addition to the foregoing fees and commissions, the
Borrower shall pay or reimburse the Issuing Lender for such normal and customary
costs and expenses as are incurred or charged by the Issuing Lender in issuing,
effecting payment under, amending, negotiating or otherwise administering any
Letter of Credit.

               (c) The Administrative Agent shall, promptly following its
receipt thereof, distribute to the Issuing Lender and the Participating Lenders
all fees and commissions received by the Administrative Agent for their
respective accounts pursuant to this subsection.

               3.4 L/C PARTICIPATIONS. (a) Effective on the Closing Date in
respect of Existing Letters of Credit, and effective on the date of issuance of
each Letter of Credit issued after the Closing Date, the Issuing Lender
irrevocably agrees to grant and hereby grants to each Participating Lender, and
each Participating Lender irrevocably agrees to accept and purchase and hereby
accepts and purchases from the Issuing
<PAGE>
                                                                              27

Lender, on the terms and conditions hereinafter stated, for such Participating
Lender's own account and risk an undivided interest equal to such Participating
Lender's Commitment Percentage in the Issuing Lender's obligations and rights
under each Letter of Credit issued by the Issuing Lender and the amount of each
draft paid by the Issuing Lender thereunder. Each Participating Lender
unconditionally and irrevocably agrees with the Issuing Lender that, if a draft
is paid under any Letter of Credit for which such Issuing Lender is not
reimbursed in full by the Borrower in accordance with the terms of this
Agreement, such Participating Lender shall pay to the Administrative Agent, for
the account of the Issuing Lender, upon demand at the Administrative Agent's
address specified in subsection 11.2, an amount equal to such Participating
Lender's Commitment Percentage of the amount of such draft, or any part thereof,
which is not so reimbursed. On the date that any Assignee becomes a Lender party
to this Agreement in accordance with subsection 11.6, participating interests in
any outstanding Letters of Credit held by the transferor Lender from which such
Assignee acquired its interest hereunder shall be proportionately reallotted
between such Assignee and such transferor Lender. Each Participating Lender
hereby agrees that its obligation to participate in each Letter of Credit, and
to pay or to reimburse the Issuing Lender for its participating share of the
drafts drawn or amounts otherwise paid thereunder, is absolute, irrevocable and
unconditional and shall not be affected by any circumstances whatsoever
(including, without limitation, the occurrence or continuance of any Default or
Event of Default), and that each such payment shall be made without offset,
abatement, withholding or other reduction whatsoever.

               (b) If any amount required to be paid by any Participating Lender
to the Issuing Lender pursuant to subsection 3.4(a) in respect of any
unreimbursed portion of any draft paid by the Issuing Lender under any Letter of
Credit is paid to the Issuing Lender within three Business Days after the date
such payment is due, such Participating Lender shall pay to the Administrative
Agent, for the account of the Issuing Lender, on demand, an amount equal to the
product of (i) such amount, times (ii) the daily average Federal Funds Effective
Rate during the period from and including the date such draft is paid to the
date on which such payment is immediately available to the Issuing Lender, times
(iii) a fraction the numerator of which is the number of days that elapse during
such period and the denominator of which is 360. If any such amount required to
be paid by any Participating Lender pursuant to subsection 3.4(a) is not in fact
made available to the Administrative Agent, for the account of the Issuing
Lender, by such Participating Lender within three Business Days after the date
such payment is due, the Issuing Lender shall be entitled to recover from such
Participating Lender, on demand, such amount with interest thereon calculated
from such due date at the rate per annum applicable to ABR Loans hereunder. A
certificate of the Issuing Lender submitted to any Participating Lender with
respect to any amounts owing under this subsection shall be conclusive in the
absence of manifest error.

               (c) Whenever, at any time after the Issuing Lender has paid a
draft under any Letter of Credit and has received from any Participating Lender
its PRO RATA share of such payment in accordance with subsection 3.4(a), the
Issuing Lender receives any reimbursement on account of such unreimbursed
portion, or any payment of interest on account thereof, the Issuing Lender will
pay to the Administrative Agent, for the account of such Participating Lender,
its PRO RATA share thereof; PROVIDED, HOWEVER, that in the event that any such
payment received by the Issuing Lender shall be required to be returned by the
Issuing Lender, such Participating Lender shall return
<PAGE>
                                                                              28

to the Administrative Agent for the account of the Issuing Lender, the portion
thereof previously distributed to it.

               3.5 REIMBURSEMENT OBLIGATION OF THE BORROWER. If any draft shall
be presented for payment under any Letter of Credit, the Issuing Lender shall
notify the Borrower and the Administrative Agent of the date and the amount
thereof. The Borrower agrees to reimburse the Issuing Lender (whether with its
own funds or with proceeds of the Revolving Credit Loans) on each date on which
the Issuing Lender pays a draft so presented under any Letter of Credit for the
amount of (i) such draft so paid and (ii) any taxes, fees, charges or other
costs or expenses incurred by the Issuing Lender in connection with such
payment. Each such payment shall be made to the Issuing Lender at its address
for notices specified herein in lawful money of the United States of America and
in immediately available funds. Interest shall be payable on any and all amounts
remaining unpaid by the Borrower under this subsection from the date of payment
of the applicable draft until payment in full thereof, (x) for the period
commencing on the date of payment of the applicable draft to the date which is 3
days thereafter, at the rate which would be payable on ABR Loans at such time
and (y) thereafter, at the rate which would be payable on ABR Loans at such time
plus 2%.

               3.6 OBLIGATIONS ABSOLUTE. The Borrower's obligations under this
Section 3 shall be absolute and unconditional under any and all circumstances
and irrespective of any set-off, counterclaim or defense to payment which the
Borrower or any other Person may have or have had against the Issuing Lender or
any other Lender or any beneficiary of a Letter of Credit. The Borrower also
agrees with the Issuing Lender that the Issuing Lender shall not be responsible
for, and the Borrower's obligations under subsection 3.5 shall not be affected
by, among other things, the validity or genuineness of documents or of any
endorsements thereon, even though such documents shall in fact prove to be
invalid, fraudulent or forged, or any dispute between or among the Borrower and
any beneficiary of any Letter of Credit or any other party to which such Letter
of Credit may be transferred or any claims whatsoever of the Borrower against
any beneficiary of such Letter of Credit or any such transferee. The Issuing
Lender shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions caused by the Issuing Lender's gross negligence or willful misconduct.
The Borrower agrees that any action taken or omitted by the Issuing Lender under
or in connection with any Letter of Credit or the related drafts or documents,
if done in the absence of gross negligence or willful misconduct and in
accordance with the standards of care specified in the Uniform Commercial Code
of the State of New York, including, without limitation, Article V thereof,
shall be binding on the Borrower and shall not result in any liability of such
Issuing Lender to the Borrower.

               3.7 LETTER OF CREDIT PAYMENTS. Without limitation of subsection
3.6, the responsibility of the Issuing Lender to the Borrower in connection with
any draft presented for payment under any Letter of Credit shall, in addition to
any payment obligation expressly provided for in such Letter of Credit, be
limited to determining that the documents (including each draft) delivered under
such Letter of Credit in connection with such presentment are in conformity with
such Letter of Credit.

               3.8 L/C APPLICATIONS. To the extent that any provision of any L/C
Application, including any reimbursement provisions contained therein, related
to any
<PAGE>
                                                                              29

Letter of Credit is inconsistent with the provisions of this Section 3, the
provisions of this Section 3 shall prevail.

                          SECTION 4. GENERAL PROVISIONS

               4.1 INTEREST RATES AND PAYMENT DATES. (a) Each Eurodollar Loan
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such
Interest Period plus the Applicable Margin in effect on such day.

               (b) Each ABR Loan shall bear interest for each day at a rate per
annum equal to the ABR in effect on such day plus the Applicable Margin in
effect on such date.

               (c) If all or a portion of (i) any principal of any Loan, (ii)
any interest payable thereon, (iii) any commitment fee or (iv) any other amount
payable hereunder shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), the principal of the Loans and any such overdue
interest, commitment fee or other amount shall bear interest at a rate per annum
which is (x) in the case of principal, the rate that would otherwise be
applicable thereto pursuant to the foregoing provisions of this subsection plus
2% or (y) in the case of any such overdue interest, commitment fee or other
amount, the ABR plus the Applicable Margin in effect on such date plus 2%, in
each case from the date of such non-payment until such overdue principal,
interest, commitment fee or other amount is paid in full (as well after as
before judgment).

               (d) Interest shall be payable in arrears on each Interest Payment
Date, PROVIDED that interest accruing pursuant to subsection 4.1(c) shall be
payable from time to time on demand.

               4.2 COMPUTATION OF INTEREST AND FEES. (a) Whenever, in the case
of ABR Loans, it is calculated on the basis of the Prime Rate, interest shall be
calculated on the basis of a 365- (or 366-, as the case may be) day year for the
actual days elapsed; and, otherwise, interest and fees shall be calculated on
the basis of a 360-day year for the actual days elapsed. The Administrative
Agent shall as soon as practicable notify the Borrower and the Lenders of each
determination of a Eurodollar Rate. Any change in the interest rate on a Loan
resulting from a change in the ABR, the Eurocurrency Reserve Requirements, the
C/D Assessment Rate or the C/D Reserve Percentage shall become effective as of
the opening of business on the day on which such change becomes effective. The
Administrative Agent shall as soon as practicable notify the Borrower and the
Lenders of the effective date and the amount of each such change in interest
rate.

               (b) Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a statement showing the quotations and calculations used by the
Administrative Agent in determining any interest rate pursuant to subsection
4.1(a).

                                                                              30

               4.3 CONVERSION AND CONTINUATION OPTIONS. (a) The Borrower may
elect from time to time to convert Eurodollar Loans to ABR Loans by giving the
Administrative Agent at least one Business Day's prior irrevocable notice of
such election, PROVIDED that any such conversion of Eurodollar Loans may only be
made on the last day of an Interest Period with respect thereto. The Borrower
may elect from time to time to convert ABR Loans to Eurodollar Loans by giving
the Administrative Agent at least three Business Days' prior irrevocable notice
of such election. Any such notice of conversion to Eurodollar Loans shall
specify the length of the initial Interest Period or Interest Periods therefor.
Upon receipt of any such notice the Administrative Agent shall promptly notify
each Lender thereof. All or any part of outstanding Eurodollar Loans and ABR
Loans may be converted as provided herein, PROVIDED that (i) no Loan may be
converted into a Eurodollar Loan when any Event of Default has occurred and is
continuing and the Administrative Agent has or the Required Lenders have
determined that such a conversion is not appropriate and (ii) no Loan may be
converted into a Eurodollar Loan after the date that is one month prior to the
Termination Date.

               (b) Any Eurodollar Loans may be continued as such upon the
expiration of the then current Interest Period with respect thereto by the
Borrower giving notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in subsection 1.1,
of the length of the next Interest Period to be applicable to such Loans,
PROVIDED that no Eurodollar Loan may be continued as such (i) when any Event of
Default has occurred and is continuing and the Administrative Agent has or the
Required Lenders have determined that such a continuation is not appropriate or
(ii) after the date that is one month prior to the Termination Date and
PROVIDED, FURTHER, that if the Borrower shall fail to give such notice or if
such continuation is not permitted such Loans shall be automatically converted
to ABR Loans on the last day of such then expiring Interest Period.

               4.4 MINIMUM AMOUNTS MAXIMUM NUMBER OF TRANCHES. All borrowings,
conversions and continuations of Loans hereunder and all selections of Interest
Periods hereunder shall be in such amounts and be made pursuant to such
elections so that, after giving effect thereto, the aggregate principal amount
of the Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or
a whole multiple of $1,000,000 in excess thereof. In no event shall there be
more than five Eurodollar Tranches outstanding at any time.

               4.5 OPTIONAL PREPAYMENTS AND COMMITMENT REDUCTIONS. (a) The
Borrower may, on the last day of any Interest Period with respect thereto, in
the case of Eurodollar Loans, or at any time and from time to time, in the case
of ABR Loans, prepay the Loans, in whole or in part, without premium or penalty,
upon at least one Business Day's irrevocable notice to the Administrative Agent
in the case of ABR Loans, and upon at least three Business Days' irrevocable
notice to the Administrative Agent in the case of Eurodollar Loans, in each case
specifying the date and amount of prepayment and whether the prepayment is of
Eurodollar Loans, ABR Loans or a combination thereof, and, in each case if of a
combination thereof, the amount allocable to each. Upon receipt of any such
notice the Administrative Agent shall promptly notify each Lender thereof. If
any such notice is given, the amount specified in such notice shall be due and
payable on the date specified therein, together with any amounts payable
pursuant to subsection 4.14. Partial prepayments shall be in an aggregate
principal amount of $5,000,000 or a whole multiple thereof.
<PAGE>
                                                                              31

               (b) Subject to subsection 4.5(c), the Borrower shall have the
right, upon not less than three Business Days' notice to the Administrative
Agent, to terminate the Revolving Credit Commitments or, from time to time, to
reduce the amount of the Revolving Credit Commitments. Any such reduction shall
be in an amount equal to $5,000,000 or a whole multiple of $1,000,000 in excess
thereof and shall reduce permanently the Revolving Credit Commitments then in
effect. Termination of the Revolving Credit Commitments shall also terminate the
obligation of the Issuing Lender to issue Letters of Credit.

               (c) In the event of any termination of the Revolving Credit
Commitments, the Borrower shall on the date of such termination repay or prepay
all of its outstanding Revolving Credit Loans (together with accrued and unpaid
interest on the Revolving Credit Loans and any amounts payable pursuant to
subsection 4.14 and any other amounts payable hereunder), reduce the Letter of
Credit Outstandings to zero and cause all Letters of Credit to be canceled and
returned to the Issuing Lender (or shall cash collateralize the Letter of Credit
Outstandings (or provide supporting letters of credit from an institution
reasonably acceptable to the Administrative Agent) on terms and pursuant to
documentation reasonably satisfactory to the Issuing Lender and the
Administrative Agent). In the event of any partial reduction of the Revolving
Credit Commitments, then (i) at or prior to the effective date of such
reduction, the Administrative Agent shall notify the Borrower and the Lenders of
the Aggregate Revolving Credit Exposure of all the Lenders and (ii) if the
Aggregate Revolving Credit Exposure of all the Lenders would exceed the
aggregate Commitments after giving effect to such reduction, then, prior to
giving effect to such reduction, the Borrower shall, on the date of such
reduction, FIRST, repay or prepay Revolving Credit Loans and, SECOND, reduce the
Letter of Credit Outstandings (or cash collateralize the Letter of Credit
Outstandings (or provide supporting letters of credit from an institution
reasonably acceptable to the Administrative Agent) on terms and pursuant to
documentation reasonably satisfactory to the Issuing Lender and the
Administrative Agent), in an aggregate amount sufficient to eliminate such
excess.

               (d) The Loans shall be repaid, and the Letter of Credit
Outstandings shall be reduced or cash collateralized, to the extent required by
subsection 4.10. All such repayments and cash collateralization shall be made in
accordance with this subsection 4.5.

               (e) In the event the amount of any prepayment of the Loans
required to be made above shall exceed the aggregate principal amount of the
outstanding ABR Loans (the amount of any such excess being called the "EXCESS
AMOUNT"), the Borrower shall have the right, in lieu of making such prepayment
in full, to prepay all the outstanding applicable ABR Loans and to deposit an
amount equal to the Excess Amount with, and (ii) in the event that Letter of
Credit Outstandings are required to be cash collateralized, the Borrower shall
deposit an amount equal to the aggregate amount of Letter of Credit Outstandings
to be cash collateralized with, the Administrative Agent in a cash collateral
account maintained (pursuant to documentation reasonably satisfactory to the
Administrative Agent) by and in the sole dominion and control of the
Administrative Agent. Any amounts so deposited shall be held by the
Administrative Agent as collateral for the obligations of the Borrower under
this Agreement and applied to the prepayment of the applicable Eurodollar Loans
at the end of the current Interest Periods applicable thereto or Letter of
Credit Outstandings, as the case may be, or, during an Event of Default, to
payment of any
<PAGE>
                                                                              32

obligations under this Agreement (including obligations in respect of the
Letters of Credit). On any Business Day on which (i) collected amounts remain on
deposit in or to the credit of such cash collateral account after giving effect
to the payments made on such day pursuant to this subsection 4.5(e) and (ii) the
Borrower shall have delivered to the Administrative Agent a written request or a
telephonic request (which shall be promptly confirmed in writing) that such
remaining collected amounts be invested in the Cash Equivalent specified in such
request, the Administrative Agent shall use its reasonable efforts to invest
such remaining collected amounts in such Cash Equivalent, PROVIDED, HOWEVER,
that the Administrative Agent shall have continuous dominion and full control
over any such investments (and over any interest that accrues thereon) to the
same extent that it has dominion and control over such cash collateral account
and no Cash Equivalent shall mature after the end of the Interest Period for
which it is to be applied. The Borrower shall not have the right to withdraw any
amount from such cash collateral account until the applicable Eurodollar Loans
and accrued interest thereon and Letter of Credit Outstandings are paid in full
or if a Default or Event of Default then exists or would result. Any prepayment
or collateralization pursuant to this subsection 4.5(e) shall be applied in the
order set forth in clause (ii) of the second sentence of subsection 4.5(c).

               4.6 COMMITMENT FEE; ADMINISTRATIVE AGENT'S FEE; OTHER FEES. (a)
The Borrower agrees to pay to the Administrative Agent for the account of each
Lender a commitment fee for the period from and including, for each Lender, the
Closing Date to but not including the Termination Date, computed at the
Commitment Fee Rate on the average daily amount of the lesser of (i) the
Available Commitment of such Lender and (ii) the Borrowing Base Availability
with respect to such Lender, during the period for which payment is made,
payable quarterly in arrears on the last day of each March, June, September and
December (commencing on June 30, 1998) and on the Termination Date or such
earlier date as the Revolving Credit Commitments shall terminate as provided
herein, commencing on the first of such dates to occur after the date hereof.
Commitment fees shall be nonrefundable when paid.

               (b) The Borrower shall pay to the Administrative Agent the fees
set forth in the fee letter agreement, dated April 4, 1998, among the Borrower,
Chase and Chase Securities Inc., and the fees set forth in the fee letter
agreement, dated April 4, 1998, between the Borrower and BT Alex.Brown
Incorporated, in each case on the dates specified therein.

               4.7 INABILITY TO DETERMINE INTEREST RATE. If prior to the first
day of any Interest Period:

               (a) the Administrative Agent shall have determined (which
        determination shall be conclusive and binding upon the Borrower) that,
        by reason of circumstances affecting the relevant market, adequate and
        reasonable means do not exist for ascertaining the Eurodollar Rate for
        such Interest Period, or

               (b) the Administrative Agent shall have received notice from the
        Required Lenders that the Eurodollar Rate determined or to be determined
        for such Interest Period will not adequately and fairly reflect the cost
        to such Lenders (as conclusively certified by such Lenders) of making or
        maintaining their affected Loans during such Interest Period,
<PAGE>
                                                                              33

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the Lenders as soon as practicable thereafter. If such notice is
given (x) any Eurodollar Loans requested to be made on the first day of such
Interest Period shall be made as ABR Loans, (y) any Loans that were to have been
converted on the first day of such Interest Period to Eurodollar Loans shall be
continued as ABR Loans and (z) any outstanding Eurodollar Loans shall be
converted, on the first day of such Interest Period, to ABR Loans. Until such
notice has been withdrawn by the Administrative Agent, no further Eurodollar
Loans shall be made or continued as such, nor shall the Borrower have the right
to convert Loans to Eurodollar Loans.

               4.8 PRO RATA TREATMENT AND PAYMENTS. (a) Each borrowing by the
Borrower from the Lenders hereunder, each payment by the Borrower on account of
any commitment fee hereunder and any reduction of the Revolving Credit
Commitments of the Lenders shall be made pro rata according to the respective
Commitment Percentages of the Lenders. Each payment (including each prepayment)
by the Borrower on account of principal of and interest on the Loans shall be
made pro rata according to the respective outstanding principal amounts of the
Loans then held by the Lenders. All payments (including prepayments) to be made
by the Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without set off or counterclaim and shall be made prior
to 12:00 Noon, New York City time, on the due date thereof to the Administrative
Agent, for the account of the Lenders, at the Administrative Agent's office
specified in subsection 11.2, in Dollars and in immediately available funds. The
Administrative Agent shall distribute such payments to the Lenders promptly upon
receipt in like funds as received. If any payment hereunder becomes due and
payable on a day other than a Business Day, such payment shall be extended to
the next succeeding Business Day, and, with respect to payments of principal,
interest thereon shall be payable at the then applicable rate during such
extension.

               (b) Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its Commitment Percentage of such borrowing
available to the Administrative Agent, the Administrative Agent may assume that
such Lender is making such amount available to the Administrative Agent, and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If such amount is not made available to the
Administrative Agent by the required time on the Borrowing Date therefor, such
Lender shall pay to the Administrative Agent, on demand, such amount with
interest thereon at a rate equal to the daily average Federal Funds Effective
Rate for the period until such Lender makes such amount immediately available to
the Administrative Agent. A certificate of the Administrative Agent submitted to
any Lender with respect to any amounts owing under this subsection shall be
conclusive in the absence of manifest error. If such Lender's Commitment
Percentage of such borrowing is not made available to the Administrative Agent
by such Lender within three Business Days after such Borrowing Date, the
Administrative Agent shall also be entitled to recover such amount with interest
thereon at the rate per annum applicable to ABR Loans hereunder, on demand, from
the Borrower.

               4.9 COMPUTATION OF BORROWING BASE. (a) BORROWING BASE. (i) The
Borrowing Base in effect from time to time shall represent the maximum principal
amount (subject to the aggregate amount of the Revolving Credit Commitments) of
<PAGE>
                                                                              34

Loans and Letter of Credit Outstandings that the Lenders will allow to remain
outstanding during the Commitment Period. During the Initial Period, the amount
of the Borrowing Base shall be $150,000,000, unless revised upon the occurrence
of a Redetermination Event, as set forth in subsection 4.9(e). The Borrowing
Base will be based upon the value of certain Proved Reserves attributable to the
Oil and Gas Properties of the Borrower and its Subsidiaries and other assets of
the Borrower and its Subsidiaries acceptable to the Administrative Agent in its
sole discretion, and will be determined by the Administrative Agent in
accordance with paragraph (d) of this subsection 4.9, subject to approval by the
Supermajority Lenders (or, with respect to the Initial Scheduled Borrowing Base
Redetermination, all of the Lenders). Until the Commitments are no longer in
effect, all Letters of Credit have terminated and all of the Loans and all other
obligations under this Agreement are paid in full, this Agreement shall be
subject to the then effective Borrowing Base.

               (b) RESERVE REPORTS. Prior to March 1 and September 1 of each
year, the Borrower shall, at its own expense, furnish to the Administrative
Agent and to each Lender Reserve Reports, which Reserve Reports shall be dated
as of the immediately preceding December 31 (in the case of Reserve Reports due
on March 1) and June 30 (in the case of Reserve Reports due on September 1), and
shall set forth, among other things, (i) the Oil and Gas Properties, then owned
by the Borrower and its Subsidiaries, (ii) the Proved Reserves attributable to
such Oil and Gas Properties and (iii) a projection of the rate of production and
net income of the Proved Reserves as of the date of such Reserve Report, all in
accordance with the guidelines published by the Securities and Exchange
Commission and such assumptions as the Administrative Agent shall provide.
Concurrently with the delivery of the Reserve Reports, the Borrower shall
furnish to the Administrative Agent and to each Lender a certificate of a
Responsible Officer showing any additions to or deletions from the Oil and Gas
Properties listed in the Reserve Report, which additions or deletions were made
by the Borrower and its Subsidiaries since the date of the previous Reserve
Report.

               (c) REDETERMINATIONS OF THE BORROWING BASE AFTER THE INITIAL
PERIOD. The Borrowing Base shall be redetermined (i) subject to the last
sentence hereof, after receipt by the Administrative Agent of each scheduled
Reserve Report, commencing with the Reserve Report as of June 30, 1998, (ii)
upon the delivery, after the Initial Period, of a Lender Redetermination Notice
to the Borrower, and (iii) upon the delivery, after the Initial Period, of a
Borrower Redetermination Notice to the Administrative Agent, all as provided in
this subsection 4.9. Within 15 days after the delivery of a Borrower
Redetermination Notice or a Lender Redetermination Notice, the Borrower shall
furnish to the Administrative Agent and to each Lender a Reserve Report as of
the most recent practicable date. If the Borrower fails to deliver a Reserve
Report within the time period provided for in the preceding sentence, then the
Administrative Agent shall have the right to rely on the last Reserve Report
previously delivered by the Borrower with any such adjustments and taking into
account any additional information as the Administrative Agent may deem
appropriate, in its sole discretion. On or before the date which is 30 days
after receipt (i) of a scheduled semi-annual Reserve Report or (ii) of a Reserve
Report in connection with a Lender Redetermination Notice or a Borrower
Redetermination Notice, the Administrative Agent shall redetermine the Borrowing
Base in its sole discretion, and the Administrative Agent shall notify the
Borrower and the Lenders of its redetermination of the Borrowing Base. Within 10
days after receipt from the Administrative Agent of the amount of the
redetermination of the Borrowing Base, each Lender shall notify the
<PAGE>
                                                                              35

Administrative Agent stating whether or not such Lender agrees with that
redetermination. Failure of any Lender to give such notice within such period of
time shall be deemed to constitute an acceptance of such redetermination. If the
Supermajority Lenders (or, with respect to the Initial Scheduled Borrowing Base
Redetermination, all of the Lenders) agree with that redetermination, then the
Administrative Agent promptly shall notify the Borrower of the Borrowing Base as
so redetermined, whereupon that redetermined value shall automatically become
effective (and shall remain effective until the Borrowing Base is again
redetermined as provided in this subsection 4.9(c)). If the Supermajority
Lenders (or, with respect to the Initial Scheduled Borrowing Base
Redetermination, all of the Lenders) have not approved or are not deemed to have
approved the Borrowing Base within the 10 day period following their receipt of
the proposed amount from the Administrative Agent, the Borrowing Base shall be
set at the amount of the then current Borrowing Base and the Borrowing Base
shall remain at such level until the Supermajority Lenders (or, with respect to
the Initial Scheduled Borrowing Base Redetermination, all of the Lenders),
utilizing the procedure outlined herein, agree on a new Borrowing Base. Each
redetermination provided for by this subsection 4.9(c) shall be made in
accordance with the provisions of subsection 4.9(d). The Borrowing Base shall be
redetermined within 45 days after the furnishing of each Reserve Report, subject
to the provisions of this paragraph (c); PROVIDED that the Initial Scheduled
Borrowing Base Redetermination shall become effective within 10 Business Days
following October 1, 1998, unless the Shell Transaction Completion Date shall
have occurred prior to such date, in which case the next sentence shall be
applicable. Notwithstanding anything in this subsection 4.9(c) to the contrary,
(i) upon the occurrence of the Shell Transaction Completion Date, the Borrowing
Base shall be $200,000,000 (minus any redetermination previously made pursuant
to the first sentence of subsection 4.9(e)) and the next scheduled
Redetermination Date shall be effective no later than April 15, 1999 and shall
be based on the December 31, 1998 Reserve Report to be delivered on or prior to
March 1, 1999 and (ii) if the Shell Transaction Completion Date occurs prior to
the effectiveness of the Initial Scheduled Borrowing Base Redetermination, such
Initial Scheduled Borrowing Base Redetermination shall not become effective.

               (d) CRITERIA. (i) All determinations and redeterminations by the
Administrative Agent provided for in this subsection 4.9 (and any determinations
and decisions by either or both of the Administrative Agent and the
Supermajority Lenders (or, with respect to the Initial Scheduled Borrowing Base
Redetermination, all of the Lenders) in connection therewith, including
effecting any redetermination of the value of any component contained in a
Reserve Report) shall be made by the Administrative Agent and the Lenders in
their sole discretion and shall be made on a reasonable basis and in good faith
based upon the application by the Administrative Agent and the Lenders of their
respective normal oil and gas lending criteria as they exist at the time of
determination.

               (ii) Subject to the last sentence in clause (c) of this
subsection 4.9, all redeterminations of the Borrowing Base referred to in this
subsection 4.9 shall become effective immediately upon the delivery of notice by
the Administrative Agent to the Borrower of the redetermination; provided that
the Initial Scheduled Borrowing Base Redetermination shall not become effective
until a date within 10 Business Days after October 1, 1998 unless the Shell
Transaction Completion Date shall have occurred prior to such date.

                                                                              36

               (iii) (x) Upon the issuance of Subordinated Indebtedness pursuant
to subsection 8.2(f) during the Initial Period, the Borrowing Base shall be
automatically reduced in accordance with subsection 4.9(e) and (y) upon the
issuance of any such Subordinated Indebtedness following the Initial Period, the
Borrowing Base shall be redetermined in accordance with the procedures set forth
in subsection 4.9 which would have applied had a Borrower Redetermination Notice
or a Lender Redetermination Notice been delivered.

               (e) REDETERMINATION EVENTS DURING THE INITIAL PERIOD. Upon the
occurrence during the Initial Period of a Redetermination Event described in
clauses (a), (b), (c) or (d) of the definition thereof, the Borrowing Base shall
be automatically reduced by an amount equal to the Net Proceeds of that
Redetermination Event and the Borrower shall promptly provide the Administrative
Agent and the Lenders notice of such a Redetermination Event and the Net
Proceeds realized therefrom (describing the same in reasonable detail). In
addition, an Oil and Gas Acquisition described in clause (e) of the definition
of Redetermination Event shall result in a mandatory redetermination of the
Borrowing Base pursuant to the procedures set forth in this subsection 4.9 for a
redetermination following the delivery of a Lender Redetermination Notice or a
Borrower Redetermination Notice; PROVIDED that any such redetermination of the
Borrowing Base must be approved by all of the Lenders.

               (f) TITLE. Concurrently with the delivery to the Administrative
Agent of each Reserve Report, the Administrative Agent may request that the
Borrower furnish to the Administrative Agent reasonable evidence of the
Borrower's title to the Oil and Gas Properties which have been developed or
acquired by the Borrower subsequent to the Reserve Report immediately preceding
such Reserve Report.

               4.10 BORROWING BASE COMPLIANCE. If, upon any redetermination of
the Borrowing Base pursuant to subsection 4.9(c) other than in connection with
the issuance of Subordinated Indebtedness provided for in subsection 8.2(f), the
Aggregate Revolving Credit Exposure of the Lenders exceeds the Borrowing Base
then in effect (any such excess, the "BORROWING BASE DEFICIENCY"), the Borrower
shall prepay the Revolving Credit Loans and then cash collateralize the Letter
of Credit Outstandings in an amount equal to at least 50% of the Borrowing Base
Deficiency within 90 days after the effective date of the redetermination
resulting in such Borrowing Base Deficiency, and within the next 90 days prepay
the Revolving Credit Loans and then cash collateralize the Letter of Credit
Outstandings in an amount equal to the balance of such Borrowing Base Deficiency
in each case together with interest accrued to the date of such payment or
prepayment and any amounts payable under subsection 4.14; PROVIDED that, if
there exists a Borrowing Base Deficiency upon the termination of the Initial
Period after giving effect to the Initial Scheduled Borrowing Base
Redetermination, the Borrower shall, within 60 days of the Initial Scheduled
Borrowing Base Redetermination, prepay the Revolving Credit Loans and then cash
collateralize the Letter of Credit Outstandings (together with interest accrued
to the date of such payment or prepayment and any amounts payable under
subsection 4.14) in an amount equal to such Borrowing Base Deficiency. If at any
other time there exists a Borrowing Base Deficiency (including as a result of a
redetermination in connection with the incurrence of Subordinated Indebtedness
provided for in subsection 8.2(f)), the Borrower shall immediately prepay the
Loans and then cash collateralize the Letter of Credit Outstandings in an amount
equal to 100% of such Borrowing Base Deficiency together with (i) interest
accrued to the date of such
<PAGE>
                                                                              37

payment or prepayment and (ii) any amounts payable under subsection 4.14.
Notwithstanding the foregoing, the Borrower shall immediately apply 100% of the
Net Proceeds of any Redetermination Event described in clauses (a), (b) (c) or
(d) of the definition thereof to prepay outstanding Loans and then cash
collateralize the Letter of Credit Outstandings. Prepayments and
collateralization pursuant to this subsection 4.10 shall be made as set forth in
subsection 4.5(c).

               4.11 ILLEGALITY. Notwithstanding any other provision herein, if
the adoption of or any change in any Requirement of Law or in the interpretation
or application thereof after the date hereof shall make it unlawful for any
Lender to make or maintain Eurodollar Loans as contemplated by this Agreement
(a) the commitment of such Lender hereunder to make Eurodollar Loans, continue
Eurodollar Loans as such and convert ABR Loans to Eurodollar Loans shall
forthwith be canceled and (b) such Lender's Loans then outstanding as Eurodollar
Loans, if any, shall be converted automatically to ABR Loans on the respective
last days of the then current Interest Periods with respect to such Loans or
within such earlier period as required by law. If any such conversion of a
Eurodollar Loan occurs on a day which is not the last day of the then current
Interest Period with respect thereto, the Borrower shall pay to such Lender such
amounts, if any, as may be required pursuant to subsection 4.14.

               4.12 REQUIREMENTS OF LAW. (a) If the adoption of or any change in
any Requirement of Law or in the interpretation or application thereof after the
date hereof or compliance by any Lender with any request or directive (whether
or not having the force of law) from any central bank or other Governmental
Authority made subsequent to the date hereof:

                    (i) shall subject any Lender to any tax of any kind
        whatsoever with respect to this Agreement, any Note, any Letter of
        Credit, any L/C Application or any Eurodollar Loan made by it, or change
        the basis of taxation of payments to such Lender in respect thereof
        (except for Non-Excluded Taxes covered by subsection 4.13, changes in
        the rate or computation of tax on the overall net income of such Lender,
        franchise taxes imposed in lieu of net income taxes and doing business
        taxes);

                   (ii) shall impose, modify or hold applicable any reserve,
        special deposit, compulsory loan or similar requirement against assets
        held by, deposits or other liabilities in or for the account of,
        advances, loans or other extensions of credit by, or any other
        acquisition of funds by, any office of such Lender which is not
        otherwise included in the determination of the Eurodollar Rate
        hereunder; or

                  (iii)  shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans or issuing or participating in
Letters of Credit or to reduce any amount receivable hereunder in respect
thereof, then, in any such case, the Borrower shall promptly pay such Lender
such additional amount or amounts as will compensate such Lender for such
increased cost or reduced amount receivable.

<PAGE>
                                                                              38

               (b) If any Lender shall have determined that the adoption of or
any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority made subsequent to the date hereof shall have the effect of reducing
the rate of return on such Lender's or such corporation's capital as a
consequence of its obligations hereunder or under any Letter of Credit to a
level below that which such Lender or such corporation could have achieved but
for such adoption, change or compliance (taking into consideration such Lender's
or such corporation's policies with respect to capital adequacy) by an amount
deemed by such Lender to be material, then from time to time, the Borrower shall
promptly pay to such Lender such additional amount or amounts as will compensate
such Lender for such reduction.

               (c) If any Lender becomes entitled to claim any additional
amounts pursuant to this subsection, it shall promptly notify the Borrower (with
a copy to the Administrative Agent) of the event by reason of which it has
become so entitled. A certificate as to any additional amounts payable pursuant
to this subsection submitted by such Lender to the Borrower (with a copy to the
Administrative Agent) shall be conclusive in the absence of manifest error. The
agreements in this subsection shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

               4.13 TAXES. (a) All payments made by the Borrower under this
Agreement and any Notes shall be made free and clear of, and without deduction
or withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or withholdings,
now or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes, franchise taxes (imposed in
lieu of net income taxes) and doing business taxes imposed on the Administrative
Agent or any Lender as a result of a present or former connection between the
Administrative Agent or such Lender and the jurisdiction of the Governmental
Authority imposing such tax or any political subdivision or taxing authority
thereof or therein (other than any such connection arising solely from the
Administrative Agent or such Lender having executed, delivered or performed its
obligations or received a payment under, or enforced, this Agreement or any
Note). If any such non-excluded taxes, levies, imposts, duties, charges, fees
deductions or withholdings ("NON-EXCLUDED TAXES") are required to be withheld
from any amounts payable to the Administrative Agent or any Lender hereunder or
under any Note, the amounts so payable to the Administrative Agent or such
Lender shall be increased to the extent necessary to yield to the Administrative
Agent or such Lender (after payment of all Non-Excluded Taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts specified in
this Agreement, PROVIDED, HOWEVER, that the Borrower shall not be required to
increase any such amounts payable to any Non-U.S. Lender if such Non-U.S. Lender
fails to comply with the requirements of paragraph (b) of this subsection.
Whenever any Non-Excluded Taxes are payable by the Borrower, as promptly as
possible thereafter the Borrower shall send to the Administrative Agent for its
own account or for the account of such Lender, as the case may be, a certified
copy of an original official receipt received by the Borrower showing payment
thereof. If, when the Borrower is required by this subsection 4.14(a) to pay any
Non-Excluded Taxes, the Borrower fails to pay any Non-Excluded Taxes when due to
the appropriate taxing authority or fails to remit to the Administrative Agent
the
<PAGE>
                                                                              39

required receipts or other required documentary evidence, the Borrower shall
indemnify the Administrative Agent and the Lenders for any incremental taxes,
interest or penalties that may become payable by the Administrative Agent or any
Lender as a result of any such failure. The agreements in this subsection shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

               (b) Each Lender (or Transferee) that is not a citizen or resident
of the United States of America, a corporation, partnership or other entity
created or organized in or under the laws of the United States of America, or
any estate or trust that is subject to federal income taxation regardless of the
source of its income (a "NON-U.S. LENDER") shall deliver to the Borrower and the
Administrative Agent (or, in the case of a Participant, to the Lender from which
the related participation shall have been purchased) two copies of either U.S.
Internal Revenue Service form 1001 or Form 4224, or, in the case of a Non-U.S.
Lender claiming exemption from U.S. federal withholding tax under Section 871(h)
or 881(c) of the Code with respect to payments of "portfolio interest," a Form
W-8, or any subsequent versions thereof or successors thereto (and, if such
Non-U.S. Lender delivers a Form W-8, an annual certificate representing that
such Non-U.S. Lender (i) is not a "bank" for purposes of Section 881(c) of the
Code (and is not subject to regulatory or other legal requirements as a bank in
any jurisdiction, and has not been treated as a bank in any filing with or
submission made to any Governmental Authority or rating agency), (ii) is not a
10% shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the
Borrower and (iii) is not a controlled foreign corporation related to the
Borrower (within the meaning of Section 864(d)(4) of the Code)), properly
completed and duly executed by such Non-U.S. Lender claiming complete exemption
from U.S. federal withholding tax on all payments by the Borrower under this
Agreement and the other Loan Documents, along with such other additional forms
as the Borrower, the Administrative Agent (or, in the case of a Participant, the
Lender from which the related participation shall have been purchased) may
reasonably request to establish the availability of such exemption. Such forms
shall be delivered by each Non-U.S. Lender on or before the date it becomes a
party to this Agreement (or, in the case of any Participant, on or before the
date such Participant purchases the related participation).

               4.14 INDEMNITY. The Borrower agrees to indemnify each Lender and
to hold each Lender harmless from any loss or expense which such Lender may
sustain or incur (other than through such Lender's gross negligence or willful
misconduct) as a consequence of (a) default by the Borrower in making a
borrowing of, conversion into or continuation of Eurodollar Loans after the
Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by the Borrower in making any
prepayment of a Eurodollar Loan after the Borrower has given a notice thereof in
accordance with the provisions of this Agreement or (c) the making of a
prepayment of or a conversion of Eurodollar Loans on a day which is not the last
day of an Interest Period with respect thereto. Such indemnification may include
an amount equal to the excess, if any, of (i) the amount of interest which would
have accrued on the amount so prepaid, or converted, or not so borrowed,
converted or continued, for the period from the date of such prepayment or
conversion or of such failure to borrow, convert or continue to the last day of
the applicable Interest Period (or, in the case of a failure to borrow, convert
or continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Eurodollar
Loans provided for herein (excluding, however, the
<PAGE>
                                                                              40

percentage added to the Eurodollar Rate pursuant to subsection 4.1(a) to the
extent included therein) over (ii) the amount of interest (as reasonably
determined by such Lender) which would have accrued to such Lender on such
amount by placing such amount on deposit for a comparable period with leading
banks in the interbank eurodollar market. This covenant shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

               4.15 CHANGE OF LENDING OFFICE. (a) Each Lender agrees that if it
makes any demand for payment under subsection 4.12 or 4.13(a), or if any
adoption or change of the type described in subsection 4.11 shall occur with
respect to it, it will use reasonable efforts (consistent with its internal
policy and legal and regulatory restrictions and so long as such efforts would
not be disadvantageous to it, as determined in its sole discretion) to designate
a different lending office if the making of such a designation would reduce or
obviate the need for the Borrower to make payments under subsection 4.12 or
4.13(a), or would eliminate or reduce the effect of any adoption or change
described in subsection 4.11.

               (b) If any Lender requests compensation under subsection 4.12, or
if the Borrower is required to pay any additional amount to any Lender or any
Governmental Authority for the account of any Lender pursuant to subsection
4.13, or if any Lender defaults in its obligation to fund Loans hereunder, then
the Borrower may, at its expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to, and such Lender promptly shall,
assign and delegate, without recourse (in accordance with and subject to the
restrictions contained in subsection 11.6), all its interests, rights and
obligations under this Agreement to an assignee that shall assume such
obligations (which assignee may be another Lender, if a Lender accepts such
assignment); PROVIDED that (i) if such assignee is not a Lender or an Affiliate
thereof, the Borrower shall have received the prior written consents of the
Administrative Agent and Issuing Lender which consents shall not unreasonably be
withheld, (ii) such Lender shall have received payment of an amount equal to the
outstanding principal of its Loans and participations in Letters of Credit,
accrued interest thereon, accrued fees and all other amounts payable to it
hereunder, from the assignee (at least to the extent of such outstanding
principal) and the Borrower (in the case of all other amounts) and (iii) in the
case of any such assignment resulting from a claim for compensation under
subsection 4.12 or payments required to be made pursuant to subsection 4.13,
such assignment will result in a reduction in such compensation or payments
compared to the compensation or payments payable to the assigning Lender. A
Lender shall not be required to make any such assignment and delegation if,
prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation
no longer exist or cease to apply.


                    SECTION 5. REPRESENTATIONS AND WARRANTIES

               To induce the Administrative Agent and the Lenders to enter into
this Agreement and to make the Loans and issue or participate in the Letters of
Credit, the Borrower hereby represents and warrants to the Administrative Agent
and each Lender that:

               5.1 FINANCIAL CONDITION. (a) The restated consolidated balance
sheets of the Borrower and its consolidated Subsidiaries at December 31, 1996
and December
<PAGE>
                                                                              41

31, 1997 and the related consolidated statements of operations, of cash flows
and of changes in stockholders' equity for the respective fiscal years ended on
such dates, together with the related notes and schedules thereto, reported on
by Ernst & Young LLP copies of which have heretofore been furnished to each
Lender, present fairly in all material respects the consolidated financial
condition of the Borrower and its consolidated Subsidiaries as at such dates,
and the consolidated results of their operations and their consolidated cash
flows for the respective fiscal years then ended, in conformity with GAAP.

               (b) All such financial statements referred to in subsection
5.1(a), including the related schedules and notes thereto, have been prepared in
accordance with GAAP applied consistently throughout the periods involved
(except as approved by such accountants or Responsible Officer, as the case may
be, and as disclosed therein). On the Closing Date, neither the Borrower nor any
of its consolidated Subsidiaries have, at the date of the most recent balance
sheet referred to above, any material Guarantee Obligation, contingent liability
or liability for taxes, or any long-term lease, outstanding debt or Lien or
unusual forward or long-term commitment, including, without limitation, any
interest rate or foreign currency swap or exchange transaction, which (i) is not
disclosed in the financial statements referred to in subsection 5.1(a) or in the
notes thereto to the extent required by GAAP or (ii) in the case of the Amoco
Litigation, does not exceed $15,000,000.

               5.2 NO CHANGE. (a) Since December 31, 1997, there has been no
development, circumstance or event which has had or could reasonably be expected
to have a Material Adverse Effect (provided that liability or accrued charges of
the Borrower of up to $15,000,000 in connection with the Amoco Litigation, in
and of itself, and any change in non-cash charges or expenses accrued by the
Borrower to meet ceiling test levels in conformity with Securities and Exchange
Commission Regulation S-X article 4-10(C)(4), in and of itself, shall not be
deemed to be a violation of this subsection 5.2(a)), and (b) during the period
from January 1, 1998 to and including the date hereof, no dividends or other
distributions have been declared, paid or made upon the Capital Stock of the
Borrower nor, except as set forth on Schedule 5.2, has any of the Capital Stock
of the Borrower been redeemed, retired, purchased or otherwise acquired for
value by the Borrower or any of its Subsidiaries.

               5.3 CORPORATE EXISTENCE; COMPLIANCE WITH LAW. Each of the
Borrower and its Subsidiaries (a) is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization, (b) has
the corporate power and authority, and the legal right, to own and operate its
Property, to lease the Property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of Property or the conduct of its business
requires such qualification except to the extent that the failure to be so
qualified and in good standing could not reasonably be expected to have, in the
aggregate, a Material Adverse Effect and (d) is in compliance with all
applicable Requirements of Law (including, without limitation, Environmental
Laws) except to the extent that the failure to comply therewith could not
reasonably be expected to have, in the aggregate, a Material Adverse Effect.

               5.4 CORPORATE POWER; AUTHORIZATION; ENFORCEABLE OBLIGATIONS. The
Borrower and each of the other Loan Parties has the corporate power and
authority,
<PAGE>
                                                                              42

and the legal right, to make, deliver and perform the Loan Documents to which it
is a party and, in the case of the Borrower, to borrow hereunder and has taken
all necessary corporate action to authorize the execution, delivery and
performance of the Loan Documents to which it is a party. No consent or
authorization of, filing with, notice to or other act by or in respect of, any
Governmental Authority or any other Person is required in connection with the
borrowings hereunder or the delivery, performance, validity or enforceability of
the Loan Documents to which each Loan Party is a party other than those which
have been obtained and are in full force and effect. This Agreement has been,
and each other Loan Document to which any Loan Party is a party will be, duly
executed and delivered on behalf of such Loan Party. This Agreement constitutes,
and each other Loan Document to which any Loan Party is a party when executed
and delivered will constitute, a legal, valid and binding obligation of such
Loan Party enforceable against such Loan Party in accordance with its terms,
subject to the effects of bankruptcy, insolvency, fraudulent transfer or
conveyance, reorganization, moratorium and other similar laws relating to or
affecting creditors' rights generally, general equitable principles (whether
considered in a proceeding in equity or at law) and an implied covenant of good
faith and fair dealing.

               5.5 NO LEGAL BAR. The execution, delivery and performance of the
Loan Documents, the granting of the Liens under the Security Documents, the
borrowings hereunder and the use of the proceeds thereof will not violate any
applicable Requirement of Law or Contractual Obligation of the Borrower or of
any of its Subsidiaries and will not result in, or require, the creation or
imposition of any Lien on any of its or their respective Properties or revenues
pursuant to any such Requirement of Law or Contractual Obligation, other than
any Lien created pursuant to the Security Documents.

               5.6 NO MATERIAL LITIGATION. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrower, threatened by or against the Borrower or any
of its Subsidiaries or against any of its or their respective Properties or
revenues (a) with respect to any of the Loan Documents or any of the
transactions contemplated hereby or thereby, or (b) which could reasonably be
expected to have a Material Adverse Effect; PROVIDED that liability or accrued
charges of the Borrower of up to $15,000,000 in connection with the Amoco
Litigation, in and of itself, shall not be deemed to be a violation of this
subsection 5.6.

               5.7 NO DEFAULT. Neither the Borrower nor any of its Subsidiaries
is in default under or with respect to any of its Contractual Obligations in any
respect which could reasonably be expected to have a Material Adverse Effect;
PROVIDED that liability of the Borrower of up to $15,000,000 in connection with
the Amoco Litigation, in and of itself, shall not be deemed to be a violation of
this subsection 5.7. No Default or Event of Default has occurred and is
continuing.

               5.8 OWNERSHIP OF PROPERTY; LIENS. (a) Except for the Oil and Gas
Properties, the Borrower and its Subsidiaries each have good title in fee simple
to, or a valid leasehold interest in, all its material real Property and
material interests in real Property, and good title to, or a valid leasehold
interest in, all its other material Property, and none of such Property is
subject to any Lien except as permitted by subsection 8.3.
<PAGE>
                                                                              43

               (b) The Borrower and its Subsidiaries each have good and
defensible title to all of its Oil and Gas Properties which are not personal
property and good title to all such Oil and Gas Properties which are personal
property and material to the Borrower and its Subsidiaries taken as a whole,
except for (i) such imperfections of title as do not in the aggregate materially
detract from the value thereof to, or the use thereof in, the business of the
Borrower or any of its Subsidiaries, (ii) Oil and Gas Properties and interests
therein disposed of since the date of the most recent Reserve Report as
permitted by subsection 8.6 hereof, (iii) imperfections of title relating to the
rights of Amoco in the Southwest Holmwood Properties, to the extent described in
the report of the Borrower on Form 10-K for the year ended December 31, 1997, as
filed with the Securities and Exchange Commission, and (iv) Liens permitted by
subsection 8.3 hereof. The quantum and nature of the interest of the Borrower
and its Subsidiaries in and to the Oil and Gas Properties as set forth in each
Reserve Report includes the entire interest of the Borrower and its Subsidiaries
in such Oil and Gas Properties as of the date of such Reserve Report and are
complete and accurate in all material respects as of the date of such Reserve
Report; and there are no "back-in" or "reversionary" interests held by third
parties which could materially reduce the interest of the Borrower and its
Subsidiaries in such Oil and Gas Properties except as expressly set forth in
such Reserve Report. The ownership of the Oil and Gas Properties by the Borrower
and its Subsidiaries shall not in any material respect obligate any such Person
to bear the costs and expenses relating to the maintenance, development or
operations of each such Oil and Gas Property in an amount in excess of the
working interest of such Person in each Oil and Gas Property set forth in the
most recent Reserve Report.

               5.9 INTELLECTUAL PROPERTY. Each of the Borrower and its
Subsidiaries owns, or is licensed to use, all trademarks, tradenames,
copyrights, technology, know-how and processes necessary for the conduct of its
business as currently conducted except for those the failure to own or license
which could not reasonably be expected to have a Material Adverse Effect (the
"INTELLECTUAL PROPERTY"). No claim has been asserted and is pending by any
Person challenging or questioning the use of any such Intellectual Property or
the validity or effectiveness of any such Intellectual Property, nor does the
Borrower know of any valid basis for any such claim which could reasonably be
expected to have a Material Adverse Effect. The use of such Intellectual
Property by the Borrower and its Subsidiaries does not infringe on the rights of
any Person, except for such claims and infringements that, in the aggregate,
could not reasonably be expected to have a Material Adverse Effect.

               5.10 NO BURDENSOME RESTRICTIONS. No applicable Requirement of Law
or Contractual Obligation of the Borrower or any of its Subsidiaries has had
during the last fiscal year of the Borrower, or could reasonable be expected to
have, a Material Adverse Effect.

               5.11 TAXES. Each of the Borrower and its Subsidiaries has filed
all material tax returns which, to the knowledge of such Loan Party, are
required to be filed by it and has paid or caused to be paid all taxes shown on
said returns and all assessments, fees and other governmental charges levied
upon it or upon any of its Property or income which are due and payable, other
than such taxes, assessments, fees and other governmental charges, if any, as
are being diligently contested in good faith and by appropriate proceedings and
with respect to which there have been established adequate reserves on the books
of the Borrower or its Subsidiaries, as the case may be,
<PAGE>
                                                                              44

in accordance with GAAP. No tax lien has been filed and, to the knowledge of the
Borrower, no claim is being asserted, with respect to any such taxes or
assessments, fees or other governmental charges.

               5.12 FEDERAL RESERVE REGULATIONS. No part of the proceeds of any
Loans will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U of the Board
of Governors of the Federal Reserve System as now and from time to time
hereafter in effect. If requested by any Lender or the Administrative Agent, the
Borrower will furnish to the Administrative Agent and each Lender a statement to
the foregoing effect in conformity with the requirements of FR Form U-1 referred
to in said Regulation U.

               5.13 ERISA. Neither a Reportable Event nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with the applicable provisions
of ERISA and the Code. No termination of a Single Employer Plan has occurred,
and no Lien in favor of the PBGC or a Plan has arisen, during such five-year
period. The present value of all accrued benefits under each Single Employer
Plan (based on those assumptions used to fund such Plans) did not, as of the
last annual valuation date prior to the date on which this representation is
made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits. Neither the Borrower nor any Commonly Controlled Entity
has had a complete or partial withdrawal from any Multiemployer Plan, and
neither the Borrower nor any Commonly Controlled Entity would become subject to
any liability under ERISA if the Borrower or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

               5.14 INVESTMENT COMPANY ACT; OTHER REGULATIONS. Neither the
Borrower nor any of its Subsidiaries is (a) an "investment company", or a
company "controlled" by an "investment company", within the meaning of the
Investment Company Act of 1940, as amended or (b) a "holding company" as defined
in, or subject to regulation under, the Public Utility Holding Company Act of
1935. Neither the Borrower nor any of its Subsidiaries is subject to regulation
under any Federal or State statute or regulation (other than Regulation X of the
Board of Governors of the Federal Reserve System) which limits its ability to
incur Indebtedness.

               5.15 SUBSIDIARIES. The Persons listed on Schedule 5.15 constitute
all the Subsidiaries of the Borrower and LOPI at the date hereof.

               5.16 PURPOSE OF LOANS. The proceeds of the Loans and the Letters
of Credit will be used (a) to refinance certain indebtedness of the Borrower,
and to pay fees and expenses related to the Shell Transactions and (b) after the
Closing Date, for working capital and for the general corporate purposes of the
Borrower and its Subsidiaries in the ordinary course of business.

               5.17 ENVIRONMENTAL MATTERS. Other than exceptions to any of the
following that could not, in the aggregate, reasonably be expected to either (a)
result in the existence of an unsatisfied liability in excess of a Material
Environmental Amount
<PAGE>
                                                                              45

or (b) give rise to a Material Adverse Effect or materially adversely affect the
value of the Mortgaged Properties taken as a whole:

               (a) each of the Borrower and its Subsidiaries: (i) is, and within
        the period of all applicable statutes of limitation has been, in
        compliance with all applicable Environmental Laws; (ii) holds all
        Environmental Permits (each of which is in full force and effect)
        required for any of its current or planned operations or for any
        Property owned, leased, or otherwise operated by it; (iii) is, and
        within the period of all applicable statutes of limitation has been, in
        compliance with all of its Environmental Permits; and (iv) reasonably
        believes that (A) each of its Environmental Permits will be timely
        renewed without expense, (B) any additional Environmental Permits which
        it has reason to believe will be required will be timely obtained
        without expense, and (C) the costs of complying with such renewed or
        additional Environmental Permits and any other Environmental Laws
        applicable to or reasonably expected to apply to the Borrower and its
        Subsidiaries will not exceed the Borrower's and its Subsidiaries'
        existing costs of complying with Environmental Permits and Environmental
        Laws.

               (b) Materials of Environmental Concern have not been transported,
        disposed of, emitted, discharged, or otherwise released or threatened to
        be released, to or at any real Property presently or formerly owned,
        leased or operated by the Borrower or any Subsidiary or at any other
        location, which could reasonably be expected to (i) give rise to
        liability of the Borrower or any Subsidiary under any applicable
        Environmental Law or (ii) interfere with the Borrower's continued
        operations.

               (c) no judicial, administrative, or arbitral proceeding
        (including any notice of violation or alleged violation) under or
        relating to any Environmental Law to which the Borrower or any
        Subsidiary is, or to the knowledge of the Borrower will be, named as a
        party is pending or, to the knowledge of the Borrower, threatened.

               (d) the Borrower has not received any written request for
        information, or been notified that it or any Subsidiary is a potentially
        responsible party under the federal Comprehensive Environmental
        Response, Compensation, and Liability Act or any similar Environmental
        Law, or with respect to any Materials
        of Environmental Concern.

               (e) neither the Borrower nor any Subsidiary has entered into or
        agreed to any consent decree, order, or settlement or other agreement,
        nor is subject to any judgment, decree, or order or other agreement, in
        any judicial, administrative, arbitral, or other forum, relating to
        compliance with or liability under any Environmental Law.

               (f) neither the Borrower nor any Subsidiary has assumed or
        retained, by contract or operation of law, any liabilities of any kind,
        fixed, contingent or otherwise, under any Environmental Law.

               5.18 NO MATERIAL MISSTATEMENTS. (a) All written information,
reports, financial statements, exhibits and schedules (including, without
limitation, the
<PAGE>
                                                                              46

Borrower's report on Form 10-K for the year ended December 31, 1997, as filed
with the Securities and Exchange Commission) furnished to the Administrative
Agent or any Lender by or on behalf of the Borrower or any of its Subsidiaries
in connection with the negotiation of any Loan Document or included therein or
delivered pursuant thereto, when taken as a whole, did not contain, and as they
may be amended, supplemented or modified from time to time, will not contain, as
of the date such statements were made, any untrue statements of a material fact
and did not omit, and as they may be amended, supplemented or modified from time
to time, will not omit, to state as of the date such statements were made, any
material fact necessary in order to make the statements contained therein, in
the light of the circumstances under which they were, are or will be made, not
materially misleading.

               (b) All projections and estimates concerning the Borrower and its
Subsidiaries that are or have been made available to the Administrative Agent or
any Lender by or on behalf of the Borrower or any of its Subsidiaries
(including, without limitation, the pro forma financial statements included in
the Confidential Information Memorandum of the Borrower dated April 1998, a copy
of which has been provided by the Borrower to each of the Lenders prior to the
date hereof), have been or will be prepared based on good faith estimates and
based upon assumptions believed by the Borrower to be reasonable in all material
respects at the time of such preparation.

               5.19 INSURANCE. Each of the Borrower and its Subsidiaries carries
and maintains with respect to its insurable properties insurance (including, to
the extent consistent with past practices, self-insurance) with financially
sound and reputable insurers of the types, to such extent and against such risks
as is customary with companies in the same or similar businesses.

               5.20 FUTURE COMMITMENTS. As of the date hereof and as of the
Closing Date, except as set forth on Schedule 5.20, on a net basis there are no
material gas imbalances, material take-or-pay or other prepayments with respect
to any Oil and Gas Property of the Borrower or any Subsidiary (or, in the case
of Oil and Gas Properties operated by operators other than the Borrower or its
Subsidiaries, to the Borrower's knowledge after reasonable investigation) which
would require the Borrower or any Subsidiary to deliver Hydrocarbons produced
from Oil and Gas Properties at some future time without then or thereafter
receiving full payment therefor.

               5.21 SECURITY DOCUMENTS. (a) The provisions of the Pledge
Agreement delivered to the Administrative Agent are effective to create in favor
of the Administrative Agent, for the ratable benefit of the Lenders, a legal,
valid and enforceable security interest in the Pledged Securities and proceeds
thereof and, when certificates representing or constituting the Pledged
Securities are delivered to the Administrative Agent, the Pledge Agreement shall
constitute a fully perfected first priority lien on, and security interest in,
all right, title and interest of the pledgor party therein in such Pledged
Securities and the proceeds thereof, in each case prior and superior in right to
any other Person.

               (b) On the Closing Date, the shares of Capital Stock listed on
Schedule I to the Pledge Agreement will constitute all the issued and
outstanding shares of Capital Stock of the direct and indirect Subsidiaries of
the Borrower; all such shares have been duly and validly issued and are fully
paid and nonassessable; and the relevant Pledgor of said shares is the record
and beneficial owner of said shares.

               (c) The provisions of the Mortgages will be effective to grant to
the Administrative Agent, for the ratable benefit of the Lenders, legal, valid
and enforceable mortgage liens on all of the right, title and interest of the
Borrower and its Subsidiaries in the mortgaged property described therein. Such
Mortgages have been recorded in the appropriate recording office and constitute
perfected first liens on, and security interest in, such mortgaged property.

               5.21. IMMATERIAL SUBSIDIARIES. The value of the assets owned by
the Immaterial Subsidiaries does not exceed $500,000 (and $1,000,000 after the
occurrence of the Shell Transaction Completion Date) in the aggregate.

               5.22 YEAR 2000 MATTERS. Any reprogramming required to permit the
proper functioning (but only to the extent that such proper functioning would
otherwise be impaired by the occurrence of the year 2000) in and following the
year 2000 of computer systems and other equipment containing embedded
microchips, in either case owned or operated by the Borrower or any of its
Subsidiaries or used or relied upon in the conduct of their business, and the
testing of all such systems and other equipment as so reprogrammed, will be
completed by January 1, 1999, except for such failures to reprogram as would
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. The costs to the Borrower and its Subsidiaries that have not
been incurred as of the date hereof for such reprogramming and testing and for
the other reasonably foreseeable consequences to them of any improper
functioning of other computer systems and equipment containing embedded
microchips due to the occurrence of the year 2000 would not reasonably be
expected to result in a Default or Event of Default or to have a Material
Adverse Effect.

        subsections 4.10, 7.7(a) or 7.9 of this Agreement, Section 8 of this
        Agreement or Section 5(b) of the Pledge Agreement; or

               (d) The Borrower or any of its Subsidiaries shall default in the
        observance or performance of any other agreement applicable to it
        contained in this Agreement or any other Loan Document (other than as
        provided in paragraphs (a) through (c) of this Section), and such
        default shall continue unremedied for a period of 30 consecutive days;
        or

               (e) The Borrower or any of its Subsidiaries shall (i) default in
        any payment of principal of or interest of any Indebtedness (excluding
        the Loans or any guarantee thereof), or in the payment of any Guarantee
        Obligation, beyond the period of grace (not to exceed 30 days), if any,
        provided in the instrument or agreement under which such Indebtedness or
        Guarantee Obligation was created; PROVIDED that the aggregate principal
        amount of such Indebtedness and Guarantee Obligations equals or exceeds
        $2,000,000 (and $4,000,000 after the occurrence of the Shell Transaction

        Obligation (or a trustee or agent on behalf of such holder or holders or
        beneficiary or beneficiaries) to cause, with the giving of notice if
        required, such Indebtedness to become due prior to its stated maturity
        or such Guarantee Obligation to become payable, PROVIDED that the
        aggregate principal amount of all such Indebtedness and Guarantee
        Obligations which would then become due and payable would equal or
        exceed $2,000,000 (and $4,000,000 after the occurrence of the Shell
        Transaction Completion Date); or

               (f) (i) The Borrower or any of its Subsidiaries shall commence

               (g) (i) Any Person shall engage in any "prohibited transaction"

        involving any Plan, (ii) any "accumulated funding deficiency" (as
        defined in Section 302 of ERISA), whether or not waived, shall exist

        of Title IV of ERISA, (iv) any Single Employer Plan shall terminate for
        purposes of Title IV of ERISA, (v) the Borrower or any Commonly

        such event or condition, together with all other such events or
        conditions, if any, could have a Material Adverse Effect; or

               (h) One or more judgments or decrees shall be entered against the
        Borrower or any Subsidiary involving in the aggregate a liability (to
        the extent not paid or covered by insurance) of $1,000,000 (and
        $2,000,000 after the occurrence of the Shell Transaction Completion
        Date) or more, and all such judgments or decrees shall not have been

               (j) The subordination provisions contained in any Subordinated

<PAGE>
                                                                              70

        writing; or

               (k) Environmental liabilities aggregating in excess of a Material
        Environmental Amount shall be outstanding at any time with respect to
        the Borrower or any of its Subsidiaries and the Borrower and such

        or

               (l) Any Lien created by the Pledge Agreement or any other
        Security Document shall cease to be enforceable and of the same effect
        and priority purported to be created thereby; or

               (m)  A Change of Control shall occur;

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) of this Section, automatically the
Commitments shall immediately terminate and the Loans hereunder (with accrued
and unpaid interest thereon) and all other amounts owing under this Agreement
(including, without limitation, all Letter of Credit Outstandings, whether or
not the beneficiaries of the then outstanding Letters of Credit shall have
presented the documents required thereunder) and the other Loan Documents shall
immediately become due and payable, and (B) if such event is any other Event of
Default, either or both of the following actions may be taken: (i) with the
consent of the Required Lenders, the Administrative Agent may, or upon the
request of the Required Lenders, the Administrative Agent shall, by written
notice to the Borrower, declare the Commitments to be terminated forthwith,
whereupon the Commitments shall immediately terminate; and (ii) with the consent
of the Required Lenders, the Administrative Agent may, or upon the request of
the Required Lenders, the Administrative Agent shall, by written notice to the
Borrower, declare the Loans hereunder (with accrued and unpaid interest thereon)
and all other amounts owing under this Agreement (including, without limitation,
all amounts of Letter of Credit Outstandings, whether or not the beneficiaries
of the then outstanding Letters of Credit shall have presented the documents
required thereunder) and the other Loan Documents to be due and payable
forthwith, whereupon the same shall immediately become due and payable.

               With respect to all Letters of Credit with respect to which
presentment for honor shall not have occurred at the time of an acceleration
pursuant to the preceding paragraph, the Borrower shall at such time deposit in
a cash collateral account opened by the Administrative Agent an amount equal to
the aggregate then unexpired amount that is available to be drawn under such
Letters of Credit. The Borrower hereby grants to the Administrative Agent, for
the benefit of the Issuing Lender and the L/C Participants, a security interest
in such cash collateral to secure all obligations of the Borrower under this
Agreement and the other Loan Documents. Amounts held in such cash collateral
account shall be applied by the Administrative Agent to the payment of drafts
drawn under such Letters of Credit, and the unused portion thereof after all
such Letters of Credit shall have expired, been cancelled or been fully drawn
upon, if any, shall be applied to repay other obligations of the Borrower
hereunder and under the Notes. After all such Letters of Credit shall have
expired, been cancelled or been fully drawn upon, all Reimbursement Obligations
shall have been satisfied and all other obligations of the Borrower hereunder
and under the other Loan Documents shall have been paid in full, the balance, if
any, in such cash collateral account shall be returned to
<PAGE>
                                                                              71

the Borrower. The Borrower shall execute and deliver to the Administrative
Agent, for the account of the Issuing Lender and the L/C Participants, such
further documents and instruments as the Administrative Agent may reasonably
request to evidence the creation and perfection of the within security interest
in such cash collateral account. Except as expressly provided above in this
Section, presentment, demand, protest and all other notices of any kind are
hereby expressly waived.

                  SECTION 10. THE ADMINISTRATIVE AGENT; OTHERS

               10.1 APPOINTMENT. Each Lender hereby irrevocably designates and
appoints Chase as Administrative Agent of such Lender under this Agreement and
the other Loan Documents, and each such Lender irrevocably authorizes the
Administrative Agent, in such capacity, to take such action on its behalf under
the provisions of this Agreement and the other Loan Documents and to exercise
such powers and perform such duties as are expressly delegated to the
Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement, the Administrative Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the
Administrative Agent.

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

               10.3 EXCULPATORY PROVISIONS. Neither the Administrative Agent nor
any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's own gross negligence or
willful misconduct) or (ii) responsible in any manner to any of the Lenders for
any recitals, statements, representations or warranties made by any Loan Party
or any officer thereof contained in this Agreement or any other Loan Document or
in any certificate, report, statement or other document referred to or provided
for in, or received by the Administrative Agent under or in connection with,
this Agreement or any other Loan Document or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document or for any failure of any Loan Party to perform its
obligations hereunder or thereunder. The Administrative Agent shall not be under
any obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books or
records of any Loan Party.

               10.4 RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent
shall be entitled to rely, and shall be fully protected in relying, upon any
Note, writing, resolution, notice, consent, certificate, affidavit, letter,
telecopy, telex or teletype message, statement, order or other document or
conversation believed by it to be
<PAGE>
                                                                              72

genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to the Loan Parties), independent accountants and other
experts selected by the Administrative Agent. The Administrative Agent may deem
and treat the payee of any Note as the owner thereof for all purposes unless a
written notice of assignment, negotiation or transfer thereof shall have been
filed with the Administrative Agent. The Administrative Agent shall be fully
justified in failing or refusing to take any action under this Agreement or any
other Loan Document unless it shall first receive such advice or concurrence of
the Required Lenders (or, where unanimous consent of the Lenders is expressly
required hereunder, such Lenders) as it deems appropriate or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action. The Administrative Agent shall in all cases be fully protected
in acting, or in refraining from acting, under this Agreement and the other Loan
Documents in accordance with a request of the Required Lenders (or, where
unanimous consent of the Lenders or the Supermajority Lenders is expressly
required hereunder, such Lenders or Supermajority Lenders, as applicable), and
such request and any action taken or failure to act pursuant thereto shall be
binding upon all the Lenders and all future holders of the Loans.

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

               10.6 NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS. Each
Lender expressly acknowledges that neither the Administrative Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact or Affiliates has
made any representations or warranties to it and that no act by the
Administrative Agent hereafter taken, including any review of the affairs of any
Loan Party, shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender. Each Lender represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, financial and other condition and
creditworthiness of each Loan Party and made its own decision to make its
Extensions of Credit hereunder and enter into this Agreement. Each Lender also
represents that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigation as
it deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness
<PAGE>
                                                                              73

of each Loan Party. Except for notices, reports and other documents expressly
required to be furnished to the Lenders by the Administrative Agent hereunder,
the Administrative Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the business,
operations, property, condition (financial or otherwise), prospects or
creditworthiness of any Loan Party which may come into the possession of the
Administrative Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or Affiliates.

               10.7 INDEMNIFICATION. The Lenders agree to indemnify the
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrower and without limiting the obligation the Borrower to do so), ratably
according to their respective Commitment Percentages in effect on the date on
which indemnification is sought, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind whatsoever which may at any time
(including, without limitation, at any time following the payment of the
obligations under this Agreement) be imposed on, incurred by or asserted against
the Administrative Agent in any way relating to or arising out of, the
Commitments, this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the
Administrative Agent under or in connection with any of the foregoing; PROVIDED
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting solely from the Administrative
Agent's gross negligence or willful misconduct. The agreements in this
subsection shall survive the payment of all obligations under this Agreement and
all other amounts payable hereunder.

               10.8 ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. The
Administrative Agent and its Affiliates may make loans to, accept deposits from
and generally engage in any kind of business with any Loan Party as though the
Administrative Agent were not the Administrative Agent hereunder and under the
other Loan Documents. With respect to the Extensions of Credit made by it, the
Administrative Agent shall have the same rights and powers under this Agreement
and the other Loan Documents as any Lender and may exercise the same as though
it were not the Administrative Agent, and the terms "Lender" and "Lenders" shall
include the Administrative Agent in its individual capacity.

               10.9 SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Lenders. If the
Administrative Agent shall resign as Administrative Agent under this Agreement
and the other Loan Documents, then the Required Lenders shall appoint from among
the Lenders a successor agent for the Lenders, which successor agent, with the
consent of the Borrower (such consent not to be unreasonably withheld or
delayed), shall succeed to the rights, powers and duties of the Administrative
Agent hereunder. Effective upon such appointment and approval, the term
"Administrative Agent" shall mean such successor agent, and the former
Administrative Agent's rights, powers and duties as Administrative Agent shall
be terminated, without any other or further act or deed on the part of such
former Administrative Agent or any of the parties to this Agreement or any
holders of the Loans. After any retiring Administrative Agent's resignation as
Administrative Agent, the provisions of this Section 10 shall inure to its
benefit as to
<PAGE>
                                                                              74

any actions taken or omitted to be taken by it while it was Administrative Agent
under this Agreement and the other Loan Documents.

               10.10 ISSUING LENDER. The provisions of this Section 10
applicable to the Administrative Agent shall apply to the Issuing Lender in the
performance of its duties under the Loan Documents, MUTATIS MUTANDIS.

               10.11 OTHERS. None of the Advisor, the Syndication Agent, the
Co-Arrangers and the Co-Documentation Agents, in such respective capacities,
shall have any duties or responsibilities, or incur any liabilities, under this
Agreement or the other Loan Documents.

                            SECTION 11. MISCELLANEOUS

               11.1 AMENDMENTS AND WAIVERS. Neither this Agreement nor any other
Loan Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this subsection. The
Required Lenders may, or, with the written consent of the Required Lenders, the
Administrative Agent may, from time to time, (a) enter into with the applicable
Loan Parties written amendments, supplements or modifications hereto and to the
other Loan Documents for the purpose of adding any provisions to this Agreement
or the other Loan Documents or changing in any manner the rights of the Lenders
or of the applicable Loan Parties hereunder or thereunder or (b) waive, on such
terms and conditions as the Required Lenders or the Administrative Agent, as the
case may be, may specify in such instrument, any of the requirements of this
Agreement or the other Loan Documents or any Default or Event of Default and its
consequences; PROVIDED, HOWEVER, that no such waiver and no such amendment,
supplement or modification shall (i) reduce the amount, or extend the scheduled
date of final maturity, of any Loan, or reduce the stated rate of any interest
or fee payable hereunder or extend the scheduled date of any payment thereof or
increase the amount or extend the expiration date of any Lender's Commitments,
in each case without the consent of each Lender affected thereby, or (ii) amend,
modify or waive any provision of this subsection or reduce the percentage
specified in the definition of Required Lenders or Supermajority Lenders (or
modify any provision of this Agreement or any other Loan Document to provide
that an action currently requiring the approval of or consent by the
Supermajority Lenders may be taken with the consent or approval by a lower
percentage of Lenders), or consent to the assignment or transfer by any Loan
Party of any of its rights and obligations under this Agreement and the other
Loan Documents other than in accordance with the terms of the applicable Loan
Documents, in each case without the written consent of all the Lenders, (iii)
release, or subordinate the interest of the Administrative Agent in, all or
substantially all of the collateral for the obligations hereunder or release all
or substantially all of the Guarantors from their respective obligations under
the Guarantee Agreement without the written consent of each Lender, (iv) change
subsection 4.8(a) or subsection 11.7(a) in a manner that would alter the pro
rata sharing of payments required thereby, without the written consent of each
Lender, or (v) amend, modify or waive any provision of Section 10 without the
written consent of the then Administrative Agent and Issuing Lender. Any
<PAGE>
                                                                              75

such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Loan Parties, the
Lenders, the Administrative Agent and all future holders of the Loans. In the
case of any waiver, the Loan Parties, the Lenders and the Administrative Agent
shall be restored to their former positions and rights hereunder and under the
other Loan Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing; no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

               11.3 NO WAIVER; CUMULATIVE REMEDIES. No failure to exercise and
no delay in exercising, on the part of the Administrative Agent, the Issuing
Lender or any Lender, any right, remedy, power or privilege hereunder or under
the other Loan Documents shall operate as a waiver thereof; nor shall any single
or partial exercise of any right, remedy, power or privilege hereunder preclude
any other or further exercise thereof or the exercise of any other right,
remedy, power or privilege. The rights, remedies, powers and privileges herein
provided are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by law.

               11.4 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties made hereunder, in the other Loan Documents and
in any document, certificate or statement delivered pursuant hereto or in

               11.5 PAYMENT OF EXPENSES AND TAXES. The Borrower agrees (a) to
pay or reimburse the Administrative Agent and its Affiliates for all their
reasonable and documented out-of-pocket costs and expenses incurred in
connection with the development, syndication, preparation and execution of, and
any amendment, supplement or modification to, this Agreement and the other Loan
Documents and any other documents prepared in connection herewith or therewith,
and the consummation and administration of the transactions contemplated hereby
and thereby, including, without limitation, the reasonable fees and
disbursements of (i) counsel to the Administrative Agent and (ii) the
Administrative Agent customarily charged by it in connection with syndicated
credits, (b) to pay or reimburse each Lender and the Administrative Agent for
all its reasonable and documented costs and expenses incurred in connection with
the enforcement or preservation of any rights under this Agreement, the other
Loan Documents and any such other documents, including, without limitation, the
reasonable fees and disbursements of counsel to the Administrative Agent and to
the several Lenders, (c) to pay, indemnify, and hold each Lender and the
Administrative Agent (and their respective Affiliates and their respective
directors, officers, employees and agents) harmless from, any and all recording
and filing fees and any and all liabilities with respect to, or resulting from
any delay in paying, stamp, excise and other taxes, if any, which may be payable
or determined to be payable in connection with the execution and delivery of, or
consummation or administration of any of the transactions contemplated by, or
any amendment, supplement or modification of, or any waiver or consent under or
in respect of, this Agreement, the other Loan Documents and any such other
documents, and (d) to pay, indemnify, and hold each Lender, the Administrative
Agent (and their respective directors, officers, employees, agents and
affiliates) harmless from and against any and all other liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever with respect to the
execution, delivery, enforcement, performance and administration of this
Agreement, the other Loan Documents or the use or the proposed use of proceeds
contemplated by this Agreement, including, without limitation, any of the
foregoing relating to the violation of, noncompliance with or liability under,
any Environmental Law applicable to any Loan Party or any of the Properties (all
the foregoing in this clause (d), collectively, the "indemnified liabilities"),
PROVIDED that the Borrower shall have no obligation under this clause (d) to any
Administrative Agent or any Lender (or any of their respective directors,
officers, employers, agents or affiliates), with respect to indemnified
liabilities to the extent such liabilities are determined by a court of
<PAGE>
                                                                              77

competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or willful misconduct of such Person. Without limiting the
foregoing, and to the extent permitted by applicable law, the Borrower agrees
not to assert, and hereby waives, and agrees to cause each of its Subsidiaries
not to assert and to so waive, all rights for contribution or any other rights
of recovery with respect to all claims, demands, penalties, fines, liabilities,
settlements, damages, costs and expenses of whatever kind or nature, under or
related to Environmental Laws, that any of them might have by statute or
otherwise against any Person entitled to indemnification under this subsection
11.5. The agreements in this subsection shall survive repayment of the Loans and
all other amounts payable hereunder and the termination of this Agreement.

               11.6 SUCCESSORS AND ASSIGNS; PARTICIPATIONS AND ASSIGNMENTS. (a)
This Agreement shall be binding upon and inure to the benefit of the Borrower,
the Lenders, the Administrative Agent, all future holders of the Loans and any
Notes hereunder and their respective successors and assigns, except that the
Borrower may not assign or transfer any of its rights or obligations under this
Agreement without the prior written consent of each Lender.

               (b) Any Lender may, in the ordinary course of its commercial
banking or lending business and in accordance with applicable law and at no cost
or expense to the Borrower, at any time sell to one or more banks or other
entities ("PARTICIPANTS") participating interests in any Loan owing to such
Lender, any Commitment of such Lender or any other interest of such Lender
hereunder and under the other Loan Documents. In the event of any such sale by a
Lender of a participating interest to a Participant, (i) such Lender's
obligations under this Agreement to the other parties to this Agreement shall
remain unchanged, (ii) such Lender shall remain solely responsible for the
performance thereof, (iii) such Lender shall remain the holder of any such Loan
(and any Note evidencing such Loan) for all purposes under this Agreement and
the other Loan Documents, (iv) the Borrower and the Administrative Agent shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement and the other Loan
Documents, and (v) in any proceeding under the Bankruptcy Code the Lender shall
be, to the extent permitted by law, the sole representative with respect to the
obligations held in the name of such Lender, whether for its own account or for
the account of any Participant. No Lender shall be entitled to create in favor
of any Participant, in the participation agreement pursuant to which such
Participant's participating interest shall be created or otherwise, any right to
vote on, consent to or approve any matter relating to this Agreement or any
other Loan Document except for those specified in clauses (i) and (ii) of the
proviso to subsection 11.1. The Borrower agrees that each Participant shall be
entitled to the benefits of subsections 4.13 and 4.14 with respect to its
participation in the Commitments and the Loans and Letters of Credit outstanding
from time to time as if it was a Lender; PROVIDED that, in the case of
subsection 4.13, such Participant shall have complied with the requirements of
said subsection and PROVIDED, FURTHER, that no Participant shall be entitled to
receive any greater amount pursuant to any such subsection than the transferor
Lender would have been entitled to receive in respect of the amount of the
participation transferred by such transferor Lender to such Participant had no
such transfer occurred.

               (c) Any Lender may, in the ordinary course of its commercial
banking or lending business and in accordance with applicable law, at any time
and from time to time assign to any Lender or, with the prior consent of each
Issuing Lender, any
<PAGE>
                                                                              78

Affiliate thereof or, with the prior written consent of the Administrative
Agent, the Borrower and each Issuing Lender (which in each case shall not be
unreasonably withheld), to an additional bank or financial institution or other
entity (an "ASSIGNEE") all or any part of its rights and obligations under this
Agreement and the other Loan Documents including, without limitation, its
Revolving Credit Commitments, L/C Commitments, Revolving Credit Loans and L/C
Participating Interests, pursuant to an Assignment and Acceptance, substantially
in the form of Exhibit G, executed by such Assignee, such assigning Lender (and,
in the case of an Assignee that is not then a Lender, by the Borrower, the
Administrative Agent and each Issuing Lender) and delivered to the
Administrative Agent for its acceptance and recording in the Register, PROVIDED
that (i) (unless the Borrower and the Administrative Agent otherwise consent in
writing) no such transfer to an Assignee (other than a Lender or any Affiliate
thereof) shall be in an aggregate principal amount less than $10,000,000 in the
aggregate (or, if less, the full amount of such assigning Lender's Revolving
Credit Loans, L/C Participating Interests and Revolving Credit Commitments) and
(ii) if any Lender assigns all or any part of its rights and obligations under
this Agreement to one of its Affiliates in connection with or in contemplation
of the sale or other disposition of its interest in such Affiliate, the
Borrower's prior written consent shall be required for such assignment. Upon
such execution, delivery, acceptance and recording, from and after the effective
date determined pursuant to such Assignment and Acceptance, (x) the Assignee
thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a Revolving Credit Commitment and L/C Commitment as set forth therein, and
(y) the assigning Lender thereunder shall, to the extent provided in such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all or the remaining
portion of an assigning Lender's rights and obligations under this Agreement,
such assigning Lender shall cease to be a party hereto). Notwithstanding any
provision of this paragraph (c) and paragraph (e) of this subsection, the
consent of the Borrower shall not be required, and, unless requested by the
Assignee and/or the assigning Lender, new Notes shall not be required to be
executed and delivered by the Borrower, for any assignment which occurs at any
time when any of the events described in subsection 9(f) shall have occurred and
be continuing.

               (d) The Administrative Agent, on behalf of the Borrower, shall
maintain at the address of the Administrative Agent referred to in subsection
11.2 a copy of each Assignment and Acceptance delivered to it and a register
(the "REGISTER") for the recordation of the names and addresses of the Lenders
and the Commitments of, and principal amounts of the Loans owing to, each Lender
from time to time. The entries in the Register shall be conclusive, in the
absence of manifest error, and the Borrower, the Administrative Agent and the
Lenders may (and, in the case of any Loan or other obligation hereunder not
evidenced by a Note, shall) treat each Person whose name is recorded in the
Register as the owner of a Loan or other obligation hereunder as the owner
thereof for all purposes of this Agreement and the other Loan Documents,
notwithstanding any notice to the contrary. Any assignment of any Loan or other
obligation hereunder not evidenced by a Note shall be effective only upon
appropriate entries with respect thereto being made in the Register. The
Register shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

                                                                              79

               (e) Notwithstanding anything in this Agreement to the contrary,
no assignment under subsection 11.6(c) of any rights or obligations under or in
respect of the Loans, the Notes or the Letters of Credit shall be effective
unless and until the Administrative Agent shall have recorded the assignment
pursuant to subsection 11.6(d). Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender and an Assignee (and, in the case of an Assignee
that is not then a Lender or an affiliate thereof, by the Borrower and the
Administrative Agent) together with payment to the Administrative Agent of a
registration and processing fee of $3,500 (other than in the case of an
assignment by a Lender to an affiliate of such Lender), the Administrative Agent
shall (i) promptly accept such Assignment and Acceptance and (ii) on the
effective date determined pursuant thereto record the information contained
therein in the Register and give notice of such acceptance and recordation to
the Lenders and the Borrower. On or prior to such effective date, the assigning
Lender shall surrender any outstanding Notes held by it all or a portion of
which are being assigned, and the Borrower, at its own expense, shall, upon the
request to the Administrative Agent by the assigning Lender or the Assignee, as
applicable, execute and deliver to the Administrative Agent (in exchange for the
outstanding Notes of the assigning Lender) a new Revolving Credit Note to the
order of such Assignee in an amount equal to the lesser of (A) the amount of
such Assignee's Revolving Credit Commitment and (B) the aggregate principal
amount of all Revolving Credit Loans made by such Assignee, after giving effect
to such Assignment and Acceptance and, if the assigning Lender has retained a
Revolving Credit Commitment hereunder, a new Revolving Credit Note to the order
of the assigning Lender in an amount equal to the lesser of (A) the amount of
such Lender's Revolving Credit Commitment and (B) the aggregate principal amount
of all Revolving Credit Loans made by such Lender, after giving effect to such
Assignment and Acceptance. Any such new Notes shall be dated the Closing Date
and shall otherwise be in the form of the Note replaced thereby. Any Notes
surrendered by the assigning Lender shall be returned by the Administrative
Agent to the Borrower marked "canceled".

               (f) The Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "TRANSFEREE") and any prospective Transferee,
any and all financial information in such Lender's possession concerning the
Loan Parties and their Affiliates which has been delivered to such Lender by or
on behalf of the Borrower pursuant to this Agreement or which has been delivered
to such Lender by or on behalf of the Borrower in connection with such Lender's
credit evaluation of the Loan Parties and their Affiliates prior to becoming a
party to this Agreement.

               (g) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this subsection concerning assignments of
Loans and Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests, including, without
limitation, any pledge or assignment by a Lender of any Loan or Note to any
Federal Reserve Bank in accordance with applicable law.

               11.7 ADJUSTMENTS; SET-OFF. (a) If any Lender (a "BENEFITTED
LENDER") shall at any time receive any payment of all or part of its Loans or
Reimbursement Obligations, or interest thereon, or receive any collateral in
respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to
events or proceedings of the nature referred to in subsection 9(f), or
otherwise), in a greater proportion than any such payment to or collateral
received by any other Lender, if any, in respect of such other
<PAGE>
                                                                              80

Lender's Loans or Reimbursement Obligations, or interest thereon, such
Benefitted Lender shall purchase for cash from the other Lenders a participating
interest in such portion of each such other Lender's Loans or Reimbursement
Obligations, or shall provide such other Lenders with the benefits of any such
collateral, or the proceeds thereof, as shall be necessary to cause such
Benefitted Lender to share the excess payment or benefits of such collateral or
proceeds ratably with each of the Lenders; PROVIDED, HOWEVER, that if all or any
portion of such excess payment or benefits is thereafter recovered from such
Benefitted Lender, such purchase shall be rescinded, and the purchase price and
benefits returned, to the extent of such recovery, but without interest.

               (b) In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Borrower hereunder (whether at the stated maturity, by acceleration or
otherwise) to set-off and appropriate and apply against such amount any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender or any branch or agency
thereof to or for the credit or the account of the Borrower, as the case may be.
Each Lender agrees promptly to notify the Borrower and the Administrative Agent
after any such set-off and application made by such Lender, PROVIDED that, to
the extent permitted by applicable law, the failure to give such notice shall
not affect the validity of such set-off and application.

               11.8 COUNTERPARTS. This Agreement may be executed by one or more
of the parties to this Agreement on any number of separate counterparts
(including by facsimile transmission), and all of said counterparts taken
together shall be deemed to constitute one and the same instrument. A set of the
copies of this Agreement signed by all the parties shall be lodged with the
Borrower and the Administrative Agent.

               11.9 SEVERABILITY. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

               11.10 INTEGRATION. This Agreement and the other Loan Documents
represent the agreement of the Borrower, the other Loan Parties, the
Administrative Agent and the Lenders with respect to the subject matter hereof,
and there are no promises, undertakings, representations or warranties by the
Administrative Agent or any Lender relative to subject matter hereof not
expressly set forth or referred to herein or in the other Loan Documents.

               11.11  GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND 
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                                                                              81

               11.12  SUBMISSION TO JURISDICTION; WAIVERS.  The Borrower hereby
irrevocably and unconditionally:

               (a) submits for itself and its property in any legal action or
        proceeding relating to this Agreement and the other Loan Documents to
        which it is a party, or for recognition and enforcement of any judgment
        in respect thereof, to the non-exclusive general jurisdiction of the
        Courts of the State of New York, the courts of the United States of
        America for the Southern District of New York, and appellate courts from
        any thereof;

               (b) consents that any such action or proceeding may be brought in
        such courts and waives any objection that it may now or hereafter have
        to the venue of any such action or proceeding in any such court or that
        such action or proceeding was brought in an inconvenient court and
        agrees not to plead or claim the same;

               (c) agrees that service of process in any such action or
        proceeding may be effected by mailing a copy thereof by registered or
        certified mail (or any substantially similar form of mail), postage
        prepaid, to the Borrower at its address set forth in subsection 11.2 or
        at such other address of which the Administrative Agent shall have been
        notified pursuant thereto;

               (d) agrees that nothing herein shall affect the right to effect
        service of process in any other manner permitted by law or shall limit
        the right to sue in any other jurisdiction; and

               (e) waives, to the maximum extent not prohibited by law, any
        right it may have to claim or recover in any legal action or proceeding
        referred to in this subsection any special, exemplary, punitive or
        consequential damages.

               11.13 ACKNOWLEDGMENTS. The Borrower hereby acknowledges that:

               (a) it has been advised by counsel in the negotiation, execution
        and delivery of this Agreement and the other Loan Documents;

               (b) neither the Administrative Agent nor any Lender has any
        fiduciary relationship with or duty to the Borrower arising out of or in
        connection with this Agreement or any of the other Loan Documents, and
        the relationship between Administrative Agent and Lenders, on one hand,
        and the Borrower, on the other hand, in connection herewith or therewith
        is solely that of debtor and creditor; and

               (c) no joint venture is created hereby or by the other Loan
        Documents or otherwise exists by virtue of the transactions contemplated
        hereby among the Lenders or among the Borrower and the Lenders.

               11.14 WAIVERS OF JURY TRIAL. THE BORROWER, THE ADMINISTRATIVE
AGENT AND THE LENDERS HEREBY KNOWINGLY AND INTENTIONALLY, IRREVOCABLY AND
UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING
TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

                                                                              82

               11.15 PRODUCTION PROCEEDS. Notwithstanding that, by the terms of
the Mortgages, Cairn is and will be assigning to the Administrative Agent and
Lenders all of the "Production Proceeds" (as defined in the Mortgage) accruing
to the property covered thereby, so long as no Event of Default has occurred
Cairn may continue to receive from the purchasers of production all such
Production Proceeds, and the Administrative Agent shall reasonably cooperate
with Cairn so that the purchasers of production pay such Production Proceeds
directly to Cairn and not to the Administrative Agent nor the Lenders. Upon the
occurrence and continuation of an Event of Default, the Administrative Agent and
Lenders may exercise all rights and remedies granted under the Mortgages,
including the right to obtain possession of all Production Proceeds then held by
Cairn or to receive directly from the purchasers of production all other
Production Proceeds. In no case shall any failure, whether purposed or
inadvertent, by the Administrative Agent or Lenders to collect directly any such
Production Proceeds constitute in any way a waiver, remission or release of any
of their rights under the Mortgages, nor shall any release of any Production
Proceeds by Administrative Agent or Lenders to Cairn constitute a waiver,
remission, or release of any other Production Proceeds or of any rights of
Administrative Agent or Lenders to collect other Production Proceeds thereunder.

               11.16 RELEASE OF MORTGAGED PROPERTIES. The Administrative Agent
is hereby authorized by the Lenders to execute, at the cost and expense of the
Borrower and pursuant to documentation reasonably acceptable to the
Administrative Agent, partial releases of the Mortgaged Properties to the extent
such Mortgaged Properties are sold in accordance with the terms of the Mortgage
and subsection 8.6.

               11.17 LIMITATION ON INTEREST. The Borrower, the Loan Parties, the
Administrative Agent and the Lenders 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 provide for interest in excess
of the maximum amount of interest permitted to be charged by applicable law from
time to time in effect. Neither any Loan Party 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. The
Administrative Agent and the Lenders 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) any Lender or may 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 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 such Lender's or 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, Lenders,

                                                                              83

the Administrative Agent and the Loan Parties (and any other payers thereof)
shall to the 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.

      WHEREAS, the Borrower and the Guarantors are engaged in related

agree with the Administrative Agent, for the ratable benefit of the Lenders,
that on the date hereof, the Amended Guarantee shall be amended and restated in
its entirety as follows:

      1. DEFINED TERMS. (a) Unless otherwise defined herein, terms defined in
the Credit Agreement and used herein shall have the meanings given to them in
the Credit Agreement.

      (b) As used herein, "OBLIGATIONS" means the collective reference to the
unpaid principal of and interest on the Loans and the Reimbursement Obligations
and all other obligations and liabilities of the Borrower (including, without
limitation, interest accruing at the then applicable rate provided in the Credit
Agreement after the maturity of the Loans and interest accruing at the then
applicable rate provided in the Credit Agreement after the filing of any
petition in bankruptcy, or the commencement of any insolvency, reorganization or
like proceeding, relating to the Borrower, whether or not a claim for
post-filing or post-petition interest is allowed in such proceeding) to the
Administrative Agent or any of the Lenders (or, in the case of any Hedging
Agreement referred to below, any Affiliate of any Lender), whether direct or
indirect, absolute or contingent, due or to become due, or now existing or
hereafter incurred, which may arise under, out of, or in connection with, the
Credit Agreement, any Notes, any Letter of Credit, the other Loan Documents or
any Hedging Agreement entered into by the Borrower with any Lender (or any
Affiliate of any Lender) or any other document made, delivered or given in
connection therewith, in each case whether on account of principal, interest,
reimbursement obligations, fees, indemnities, costs, expenses or otherwise
(including, without limitation, all fees and disbursements of counsel to the
Administrative Agent or to the Lenders that are required to be paid by the
Borrower or the Guarantors pursuant to the terms of the Credit Agreement or this
Agreement or any other Loan Document).
<PAGE>
                                                                               3

      (c) The words "hereof," "herein" and "hereunder" and words of similar
import when used in this Guarantee shall refer to this Guarantee as a whole and
not to any particular provision of this Guarantee, and section and paragraph
references are to this Guarantee unless otherwise specified.

      (d) The meanings given to terms defined herein shall be equally applicable
to both the singular and plural forms of such terms.

      2. GUARANTEE. (a) Subject to the provisions of paragraph 2(b), each of the
Guarantors hereby, jointly and severally, unconditionally and irrevocably,
guarantees to the Administrative Agent, for the ratable benefit of the Lenders
and their respective successors, indorsees, transferees and assigns, the prompt
and complete payment and performance by the Borrower when due (whether at the
stated maturity, by acceleration or otherwise) of the Obligations.

      (b) Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of each Guarantor hereunder and under the
other Loan Documents shall in no event exceed the amount which can be guaranteed
by such Guarantor under applicable federal and state laws relating to the
insolvency of debtors (after giving affect to the right of contribution
established in Section 3).

      (c) Each Guarantor further agrees to pay any and all expenses (including,
without limitation, all fees and disbursements of counsel) which may be paid or
incurred by the Administrative Agent or any Lender in enforcing, or obtaining
advice of counsel in respect of, any rights with respect to, or collecting, any
or all of the Obligations and/or enforcing any rights with respect to, or
collecting against, such Guarantor under this Guarantee. This Guarantee shall
remain in full force and effect until the Obligations are paid in full, no
Letter of Credit shall be outstanding, and the Commitments are terminated,
notwithstanding that from time to time prior thereto the Borrower may be free
from any Obligations.

      (d) Each Guarantor agrees that the Obligations may at any time and from
time to time exceed the amount of the liability of such Guarantor hereunder
without impairing this Guarantee or affecting the rights and remedies of the
Administrative Agent or any Lender hereunder.

      (e) No payment or payments made by the Borrower, any of the Guarantors,
any other guarantor or any other Person or received or collected by the
Administrative Agent or any Lender from the Borrower, any of the Guarantors, any
other guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application at any time or from time to time in
reduction of or in payment of the Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of any Guarantor hereunder which
shall, notwithstanding any such payment or payments other than payments made by
such Guarantor in respect of the Obligations or payments received or collected
from such Guarantor in respect of the Obligations, remain liable for the
Obligations up to the maximum liability of such Guarantor hereunder until the
Obligations are paid in full, no Letter of Credit shall be outstanding, and the
Commitments are terminated.
<PAGE>
                                                                               4

      (f) Each Guarantor agrees that whenever, at any time, or from time to
time, it shall make any payment to the Administrative Agent or any Lender on
account of its liability hereunder, it will notify the Administrative Agent in
writing that such payment is made under this Guarantee for such purpose.

      3. RIGHT OF CONTRIBUTION. Each Guarantor hereby agrees that to the extent
that a Guarantor shall have paid more than its proportionate share of any
payment made hereunder, such Guarantor shall be entitled to seek and receive
contribution from and against any other Guarantor hereunder who has not paid its
proportionate share of such payment. Each Guarantor's right of contribution
shall be subject to the terms and conditions of Section 5 hereof. The provisions
of this Section shall in no respect limit the obligations and liabilities of any
Guarantor to the Administrative Agent and the Lenders, and each Guarantor shall
remain liable to the Administrative Agent and the Lenders for the full amount
guaranteed by such Guarantor hereunder.

      4. RIGHT OF SET-OFF. Each Guarantor hereby irrevocably authorizes each
Lender at any time and from time to time, so long as an Event of Default has
occurred and is continuing, without notice to such Guarantor or any other
Guarantor, any such notice being expressly waived by each Guarantor, to set-off
and appropriate and apply any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Lender to or for the credit or the account of such Guarantor, or
any part thereof in such amounts as such Lender may elect, against and on
account of the obligations and liabilities of such Guarantor to such Lender
hereunder and claims of every nature and description of such Lender against such
Guarantor, in any currency, whether arising hereunder, under the Credit
Agreement, any Note, any Letter of Credit, any other Loan Document or otherwise,
as such Lender may elect, whether or not the Administrative Agent or any Lender
has made any demand for payment and although such obligations, liabilities and
claims may be contingent or unmatured. The Administrative Agent and each Lender
shall notify such Guarantor promptly of any such set-off and the application
made by the Administrative Agent or such Lender, PROVIDED that the failure to
give such notice shall not affect the validity of such set-off and application.
The rights of the Administrative Agent and each Lender under this Section are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) which the Administrative Agent or such Lender may have.

      5. NO SUBROGATION. Notwithstanding any payment or payments made by any of
the Guarantors hereunder or any set-off or application of funds of any of the
Guarantors by the Administrative Agent or any Lender, no Guarantor shall be
entitled to be subrogated to any of the rights of the Administrative Agent or
any Lender against the Borrower or any other Guarantor or any collateral
security or guarantee or right of offset held by any Lender for the payment of
the Obligations, nor shall any Guarantor seek or be entitled to seek any
contribution or reimbursement from the Borrower or any other Guarantor in
respect of payments made by such Guarantor hereunder, until all amounts owing to
the Administrative Agent and the Lenders by the 
<PAGE>
                                                                               5

Borrower on account of the Obligations are paid in full, no Letter of Credit
shall be outstanding and the Commitments are terminated. If any amount shall be
paid to any Guarantor on account of such subrogation rights at any time when all
of the Obligations shall not have been paid in full, such amount shall be held
by such Guarantor in trust for the Administrative Agent and the Lenders,
segregated from other funds of such Guarantor, and shall, forthwith upon receipt
by such Guarantor, be turned over to the Administrative Agent in the exact form
received by such Guarantor (duly indorsed by such Guarantor to the
Administrative Agent, if required), to be applied against the Obligations,
whether matured or unmatured, in such order as the Administrative Agent may
determine.

      6. AMENDMENTS, ETC. WITH RESPECT TO THE OBLIGATIONS; WAIVER OF RIGHTS.
Each Guarantor shall remain obligated hereunder notwithstanding that, without
any reservation of rights against any Guarantor and without notice to or further
assent by any Guarantor, any demand for payment of any of the Obligations made
by the Administrative Agent or any Lender may be rescinded by such Person and
any of the Obligations continued, and the Obligations, or the liability of any
other Person upon or for any part thereof, or any collateral security or
guarantee therefor or right of offset with respect thereto, may, from time to
time, in whole or in part, be renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released by the Administrative Agent or any
Lender, and the Credit Agreement, any Notes and the other Loan Documents and any
other documents executed and delivered in connection therewith may be amended,
modified, supplemented or terminated, in whole or in part, as the Administrative
Agent (or the Required Lenders, as the case may be) may deem advisable from time
to time, and any collateral security, guarantee or right of offset at any time
held by the Administrative Agent or any Lender for the payment of the
Obligations may be sold, exchanged, waived, surrendered or released. Neither the
Administrative Agent nor any Lender shall have any obligation to protect,
secure, perfect or insure any Lien at any time held by it as security for the
Obligations or for this Guarantee or any property subject thereto. When making
any demand hereunder against any of the Guarantors, the Administrative Agent or
any Lender may, but shall be under no obligation to, make a similar demand on
the Borrower or any other Guarantor or guarantor, and any failure by the
Administrative Agent or any Lender to make any such demand or to collect any
payments from the Borrower or any such other Guarantor or guarantor or any
release of the Borrower or such other Guarantor or guarantor shall not relieve
any of the Guarantors in respect of which a demand or collection is not made or
any of the Guarantors not so released of their several obligations or
liabilities hereunder, and shall not impair or affect the rights and remedies,
express or implied, or as a matter of law, of the Administrative Agent or any
Lender against any of the Guarantors. For the purposes hereof "demand" shall
include the commencement and continuance of any legal proceedings.

      7. GUARANTEE ABSOLUTE AND UNCONDITIONAL. Each Guarantor waives any and all
notice of the creation, renewal, extension or accrual of any of the Obligations
and notice of or proof of reliance by the Administrative Agent or any Lender
upon this Guarantee or acceptance of this Guarantee, the Obligations, and any of
them, shall conclusively be deemed to have been created, contracted or incurred,
or renewed, extended, amended or waived, in reliance upon this 
<PAGE>
                                                                               6

Guarantee; and all dealings between the Borrower and any of the Guarantors, on
the one hand, and the Administrative Agent and the Lenders, on the other hand,
likewise shall be conclusively presumed to have been had or consummated in
reliance upon this Guarantee. Each Guarantor waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon the
Borrower or any of the Guarantors with respect to the Obligations. Each
Guarantor understands and agrees that this Guarantee shall be construed as a
continuing, absolute and unconditional guarantee of payment without regard to
(a) the validity, regularity or enforceability of the Credit Agreement, any Note
or any other Loan Document, any of the Obligations or any other collateral
security therefor or guarantee or right of offset with respect thereto at any
time or from time to time held by the Administrative Agent or any Lender (b) any
defense, set-off or counterclaim (other than a defense of payment or
performance) which may at any time be available to or be asserted by the
Borrower against the Administrative Agent or any Lender, or (c) any other
circumstance whatsoever (with or without notice to or knowledge of the Borrower
or such Guarantor) which constitutes, or might be construed to constitute, an
equitable or legal discharge of the Borrower for the Obligations, or of such
Guarantor under this Guarantee, in bankruptcy or in any other instance. When
pursuing its rights and remedies hereunder against any Guarantor, the
Administrative Agent and any Lender may, but shall be under no obligation to,
pursue such rights and remedies as it may have against the Borrower or any other
Person or against any collateral security or guarantee for the Obligations or
any right of offset with respect thereto, and any failure by the Administrative
Agent or any Lender to pursue such other rights or remedies or to collect any
payments from the Borrower or any such other Person or to realize upon any such
collateral security or guarantee or to exercise any such right of offset, or any
release of the Borrower or any such other Person or any such collateral
security, guarantee or right of offset, shall not relieve such Guarantor of any
liability hereunder, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of the Administrative
Agent and the Lenders against such Guarantor. This Guarantee shall remain in
full force and effect and be binding in accordance with and to the extent of its
terms upon each Guarantor and the successors and assigns thereof, and shall
inure to the benefit of the Administrative Agent and the Lenders, and their
respective successors, indorsees, transferees and assigns, until all the
Obligations and the obligations of each Guarantor under this Guarantee shall
have been satisfied by payment in full, no Letter of Credit shall be
outstanding, and the Commitments shall be terminated, notwithstanding that from
time to time during the term of the Credit Agreement the Borrower may be free
from any Obligations.

      8. REINSTATEMENT. This Guarantee shall continue to be effective, or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
any of the Obligations is rescinded or must otherwise be restored or returned by
the Administrative Agent or any Lender upon the insolvency, bankruptcy,
dissolution, liquidation or reorganization of the Borrower or any Guarantor, or
upon or as a result of the appointment of a receiver, intervenor or conservator
of, or trustee or similar officer for, the Borrower or any Guarantor or any
substantial part of its property, or otherwise, all as though such payments had
not been made.

      9. PAYMENTS. Each Guarantor hereby guarantees that payments hereunder will

New York 10017.

      10. REPRESENTATIONS AND WARRANTIES. Each Guarantor hereby represents and
warrants to the Administrative Agent and each Lender that, the representations
and warranties set forth in Section 5 of the Credit Agreement as they relate to
such Guarantor or to the Loan Documents to which such Guarantor is a party, each
of which is hereby incorporated herein by reference, are true and correct, and
the Administrative Agent and each Lender shall be entitled to rely on each of
them as if they were fully set forth herein; PROVIDED that each reference in
each such representation and warranty to the Borrower's knowledge shall, for the
purposes of this Section 10 be deemed to be a reference to such Guarantor's
knowledge.

warranties shall be deemed to have been made by such Guarantor on the date of
each Extension of Credit under the Credit Agreement on and as of such date of
Extension of Credit as though made hereunder on and as of such date.

      11. COVENANTS. Each Guarantor covenants and agrees with the Administrative
Agent and each Lender that, from and after the date of this Guarantee until the
Obligations shall have been paid in full, no Letter of Credit shall be
outstanding and the Commitments shall have terminated, such Guarantor shall
take, or shall refrain from taking, as the case may be, each action that is
necessary to be taken or not taken, as the case may be, so that no Default or
Event of Default is caused by the failure to take such action or to refrain from
taking such action by such Guarantor or any of its Subsidiaries.

      12. AUTHORITY OF ADMINISTRATIVE AGENT. Each Guarantor acknowledges that
the rights and responsibilities of the Administrative Agent under this Guarantee
with respect to any action taken by the Administrative Agent or the exercise or
non-exercise by the Administrative Agent of any option, right, request, judgment
or other right or remedy provided for herein or resulting or arising out of this
Guarantee shall, as between the Administrative Agent and the Lenders, be
governed by the Credit Agreement and by such other agreements with respect
thereto as may exist from time to time among them, but, as between the
Administrative Agent and such Guarantor, the Administrative Agent shall be
conclusively presumed to be acting as agent for the Lenders with full and valid
authority so to act or refrain from acting, and no Guarantor shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

      13. NOTICES. All notices, requests and demands to or upon the
Administrative Agent, any Lender or any Guarantor shall be effected in the
manner provided for in subsection 11.2 of the Credit Agreement, addressed as
follows:

<PAGE>
                                                                               8

this Section.

      14. COUNTERPARTS. This Guarantee may be executed by one or more of the
Guarantors on any number of separate counterparts, and all of said counterparts
taken together shall be deemed to constitute one and the same instrument.

      15. SEVERABILITY. Any provision of this Guarantee which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

      16. INTEGRATION. This Guarantee represents the agreement of each Guarantor
with respect to the subject matter hereof and there are no promises or
representations by the Administrative Agent or any Lender relative to the
subject matter hereof not reflected herein.

      17. AMENDMENTS IN WRITING; NO WAIVER; CUMULATIVE REMEDIES. (a) None of the
terms or provisions of this Guarantee may be waived, amended, supplemented or
otherwise modified except in accordance with subsection 11.1 of the Credit
Agreement.

      (b) Neither the Administrative Agent nor any Lender shall by any act
(except by a written instrument pursuant to paragraph 17(a) hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any Default or Event of Default or in any
breach of any of the terms and conditions hereof. No failure to exercise, nor
any delay in exercising, on the part of the Administrative Agent or any Lender,
any right, power or privilege hereunder shall operate as a waiver thereof. No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. A waiver by the Administrative Agent or any Lender of
any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which the Administrative Agent or such Lender would
otherwise have on any future occasion.

      (c) The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

         5. COVENANTS. Each Pledgor covenants and agrees with the Administrative
Agent and the Lenders that, from and after the date of this Agreement until this
Agreement is terminated and the security interests created hereby are released:

         (a) If such Pledgor shall, as a result of its ownership of the Pledged
Stock, become entitled to receive or shall receive any stock certificate
(including, without limitation, any certificate representing a stock dividend or
a distribution in connection with any reclassification, increase or reduction of
capital or any certificate issued in connection with any reorganization), option
or rights, whether in addition to, in substitution of, as a conversion of, or in
exchange for any shares of the Pledged Stock, or otherwise in respect thereof,
such Pledgor shall accept the same as the agent of the Administrative Agent and
the Lenders, hold the same in trust for the Agent and the Lenders and deliver
the same forthwith to the Agent in the exact form received, duly indorsed by
such Pledgor to the Administrative Agent, if required, together with an undated
stock power covering such certificate duly executed in blank by such Pledgor and
with, if the Administrative Agent so requests, signature guaranteed, to be held
by the Administrative Agent, subject to the terms hereof, as additional
collateral security for the Secured Obligations. Any sums paid upon or in
respect of the Pledged Stock upon the liquidation or dissolution of any Issuer
shall be paid over to the Administrative Agent to be held by it hereunder as
additional collateral security for the Secured Obligations, and in case any
distribution of capital shall be made on or in respect of the Pledged Stock or
any property shall be distributed upon or with respect to the Pledged Stock
pursuant to the recapitalization or reclassification of the capital of any
Issuer or pursuant to the reorganization thereof, the property so distributed
shall be delivered to the Administrative Agent to be held by it hereunder as
additional collateral security for the Secured Obligations. If any sums of money
or property so paid or distributed in respect of the Pledged Stock shall be
received by such Pledgor, such Pledgor shall, until such money or property is
paid or delivered to the Administrative Agent, hold such money or property in
trust for the Lenders, segregated from other funds of such Pledgor, as
additional collateral security for the Secured Obligations.

         (b) Without the prior written consent of the Administrative Agent, such
Pledgor shall not (1) vote to enable, or take any other action to permit, any
Issuer to issue any stock or other equity securities of any nature or to issue
any other securities convertible into or granting the right to purchase or
exchange for any stock or other equity securities of any nature of any Issuer,
(2) sell, assign, transfer, exchange, or otherwise dispose of, or grant any
option with respect to, the Collateral, (3) create, incur or permit to exist any
Lien or option in favor of, or any claim of any Person with respect to, any of
the Collateral, or any interest therein, except for the security interests
created by this Agreement or (4) enter into any agreement or undertaking
restricting the
<PAGE>
                                                                               5

right or ability of such Pledgor or the Administrative Agent to sell, assign or
transfer any of the Collateral.

         (c) Such Pledgor shall maintain the security interest created by this
Agreement as a first, perfected security interest and shall defend such security
interest against claims and demands of all Persons whomsoever. At any time and
from time to time, upon the written request of the Administrative Agent, and at
the sole expense of such Pledgor, such Pledgor will promptly and duly execute
and deliver such further instruments and documents and take such further actions
as the Administrative Agent may reasonably request for the purposes of obtaining
or preserving the full benefits of this Agreement and of the rights and powers
herein granted. If any amount payable under or in connection with any of the
Collateral shall be or become evidenced by any promissory note, other instrument
or chattel paper, such note, instrument or chattel paper shall be immediately
delivered to the Administrative Agent, duly endorsed in a manner satisfactory to
the Administrative Agent, to be held as Collateral pursuant to this Agreement.

         (d) Such Pledgor shall pay, and save the Administrative Agent and the
Lenders harmless from, any and all liabilities with respect to, or resulting
from any delay in paying, any and all stamp, excise, sales or other taxes which
may be payable or determined to be payable with respect to any of the Collateral
or in connection with any of the transactions contemplated by this Agreement.

         6. CASH DIVIDENDS; VOTING RIGHTS. Unless an Event of Default shall have
occurred and be continuing and the Administrative Agent shall have given notice
to a Pledgor or Pledgors of the Administrative Agent's intent to exercise its
corresponding rights pursuant to Section 7 below, all Pledgors shall be
permitted to receive all cash dividends paid in the normal course of business of
the Issuers, to the extent permitted in the Credit Agreement, in respect of the
Pledged Stock and to exercise all voting and corporate rights with respect to
the Pledged Stock; PROVIDED, HOWEVER, that no vote shall be cast or corporate
right exercised or other action taken which, in the Administrative Agent's
reasonable judgment, would impair the Collateral or which would be inconsistent
with or result in any violation of any provision of the Credit Agreement, the
Notes, this Agreement or any other Loan Document.

         7. RIGHTS OF THE LENDERS AND THE ADMINISTRATIVE AGENT. (a) All money
Proceeds received by the Administrative Agent hereunder shall be held by the
Administrative Agent for the benefit of the Lenders in a Collateral Account. All
Proceeds while held by the Administrative Agent in a Collateral Account (or by a
Pledgor in trust for the Administrative Agent and the Lenders) shall continue to
be held as collateral security for all the Secured Obligations and shall not
constitute payment thereof until applied as provided in paragraph 8(a).

         (b) If an Event of Default shall occur and be continuing and the
Administrative Agent shall give notice of its intent to exercise such rights to
the relevant Pledgor or Pledgors, (1) the Administrative Agent shall have the
right to receive any and all cash dividends paid in respect of the Pledged Stock
and make application thereof to the Secured Obligations in such order as the
Administrative Agent may determine, and (2) all shares of the Pledged Stock
shall be registered in
<PAGE>
                                                                               6

the name of the Administrative Agent or its nominee, and the Administrative
Agent or its nominee may thereafter exercise (A) all voting, corporate and other
rights pertaining to such shares of the Pledged Stock at any meeting of
shareholders of the applicable Issuer or Issuers or otherwise and (B) any and
all rights of conversion, exchange, subscription and any other rights,
privileges or options pertaining to such shares of the Pledged Stock as if it
were the absolute owner thereof (including, without limitation, the right to
exchange at its discretion any and all of the Pledged Stock upon the merger,
consolidation, reorganization, recapitalization or other fundamental change in
the corporate structure of such Issuer, or upon the exercise by such Pledgor or
the Administrative Agent of any right, privilege or option pertaining to such
shares of the Pledged Stock, and in connection therewith, the right to deposit
and deliver any and all of the Pledged Stock with any committee, depositary,
transfer agent, registrar or other designated agency upon such terms and
conditions as the Administrative Agent may determine), all without liability
except to account for property actually received by it, but the Administrative
Agent shall have no duty to such Pledgor to exercise any such right, privilege
or option and shall not be responsible for any failure to do so or delay in so
doing.

         8. REMEDIES. (a) If an Event of Default shall have occurred and be
continuing, at any time at the Administrative Agent's election, the
Administrative Agent may apply all or any part of Proceeds held in any
Collateral Account in payment of the Secured Obligations in such order as the
Administrative Agent may elect.

         (b) If an Event of Default shall occur and be continuing, the
Administrative Agent, on behalf of the Lenders, may exercise, in addition to all
other rights and remedies granted in this Agreement and in any other instrument
or agreement securing, evidencing or relating to the Secured Obligations, all
rights and remedies of a secured party under the Code. Without limiting the
generality of the foregoing, the Administrative Agent, without demand of
performance or other demand, presentment, protest, advertisement or notice of
any kind (except any notice required by law referred to below) to or upon any
Pledgor or any other Person (all and each of which demands, defenses,
advertisements and notices are hereby waived), may in such circumstances
forthwith collect, receive, appropriate and realize upon the Collateral, or any
part thereof, and/or may forthwith sell, assign, give option or options to
purchase or otherwise dispose of and deliver the Collateral or any part thereof
(or contract to do any of the foregoing), in one or more parcels at public or
private sale or sales, in the over-the-counter market, at any exchange, broker's
board or office of the Administrative Agent or any Lender or elsewhere upon such
terms and conditions as it may deem advisable and at such prices as it may deem
best, for cash or on credit or for future delivery without assumption of any
credit risk. The Administrative Agent or any Lender shall have the right upon
any such public sale or sales, and, to the extent permitted by law, upon any
such private sale or sales, to purchase the whole or any part of the Collateral
so sold, free of any right or equity of redemption in the relevant Pledgor,
which right or equity is hereby waived or released. The Administrative Agent
shall apply any Proceeds from time to time held by it and the net proceeds of
any such collection, recovery, receipt, appropriation, realization or sale,
after deducting all reasonable costs and expenses of every kind incurred in
respect thereof or incidental to the care or safekeeping of any of the
Collateral or in any way relating to the Collateral or the rights of the
Administrative Agent and the Lenders hereunder, including, without
<PAGE>
                                                                               7

limitation, reasonable attorneys' fees and disbursements of counsel to the
Administrative Agent, to the payment in whole or in part of the Secured
Obligations, in such order as the Administrative Agent may elect, and only after
such application and after the payment by the Administrative Agent of any other
amount required by any provision of law, including, without limitation, Section
9-504(1)(c) of the Code, need the Administrative Agent account for the surplus,
if any, to the relevant Pledgor. To the extent permitted by applicable law, each
Pledgor waives all claims, damages and demands it may acquire against the
Administrative Agent or any Lender arising out of the exercise by them of any
rights hereunder. If any notice of a proposed sale or other disposition of
Collateral shall be required by law, such notice shall be deemed reasonable and
proper if given at least 10 days before such sale or other disposition.

         (c) Each Pledgor waives and agrees not to assert any rights or
privileges which it may acquire under Section 9-112 of the Code. The Pledgors
shall remain liable for any deficiency if the proceeds of any sale or other
disposition of Collateral are insufficient to pay the Secured Obligations and
the fees and disbursements of any attorneys employed by the Administrative Agent
or any Lender to collect such deficiency.

         9. REGISTRATION RIGHTS; PRIVATE SALES. (a) If the Administrative Agent
shall determine to exercise its right to sell any or all of the Pledged Stock
pursuant to paragraph 8(b) hereof, and if in the opinion of the Administrative
Agent it is necessary or advisable to have the Pledged Stock, or that portion
thereof to be sold, registered under the provisions of the Securities Act, each
Pledgor will cause the Issuer thereof to (1) execute and deliver, and cause the
directors and officers of such Issuer to execute and deliver, all such
instruments and documents, and do or cause to be done all such other acts as may
be, in the opinion of the Administrative Agent, necessary or advisable to
register the Pledged Stock, or that portion thereof to be sold, under the
provisions of the Securities Act, (2) to use its best efforts to cause the
registration statement relating thereto to become effective and to remain
effective for a period of one year from the date of the first public offering of
the Pledged Stock, or that portion thereof to be sold, and (3) to make all
amendments thereto and/or to the related prospectus which, in the opinion of the
Administrative Agent, are necessary or advisable, all in conformity with the
requirements of the Securities Act and the rules and regulations of the
Securities and Exchange Commission applicable thereto. Each Pledgor agrees to
cause such Issuer to comply with the provisions of the securities or "Blue Sky"
laws of any and all jurisdictions which the Administrative Agent shall designate
and to make available to its security holders, as soon as practicable, an
earnings statement (which need not be audited) which will satisfy the provisions
of Section 11(a) of the Securities Act.

         (b) Each Pledgor recognizes that the Administrative Agent may be unable
to effect a public sale of any or all the Pledged Stock, by reason of certain
prohibitions contained in the Securities Act and applicable state securities
laws or otherwise, and may be compelled to resort to one or more private sales
thereof to a restricted group of purchasers which will be obliged to agree,
among other things, to acquire such securities for their own account for
investment and not with a view to the distribution or resale thereof. Each
Pledgor acknowledges and agrees that any such private sale may result in prices
and other terms less favorable than if such sale were a public
<PAGE>
                                                                               8

sale and, notwithstanding such circumstances, agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The
Administrative Agent shall be under no obligation to delay a sale of any of the
Pledged Stock for the period of time necessary to permit the Issuer thereof to
register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if such Issuer would agree to do so.

         (c) Each Pledgor further agrees to use its best efforts to do or cause
to be done all such other acts as may be necessary to make such sale or sales of
all or any portion of the Pledged Stock pursuant to this Section 9 valid and
binding and in compliance with any and all other applicable Requirements of Law.
Each Pledgor further agrees that a breach of any of the covenants contained in
this Section 9 will cause irreparable injury to the Administrative Agent and the
Lenders, that the Administrative Agent and the Lenders have no adequate remedy
at law in respect of such breach and, as a consequence, that each and every
covenant contained in this Section shall be specifically enforceable against
such Pledgor, and such Pledgor hereby waives and agrees not to assert any
defenses against an action for specific performance of such covenants except for
a defense that no Event of Default has occurred under the Credit Agreement.

         10. IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO ISSUER. Each Pledgor
hereby authorizes and instructs each Issuer to comply with any instruction
received by it from the Administrative Agent in writing that (a) states that an
Event of Default has occurred and (b) is otherwise in accordance with the terms
of this Agreement, without any other or further instructions from such Pledgor,
and each Pledgor agrees that each Issuer shall be fully protected in so
complying.

         11. ADMINISTRATIVE AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT. (a) Each
Pledgor hereby irrevocably constitutes and appoints the Administrative Agent and
any officer or agent of the Administrative Agent, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of such Pledgor and in the name of
such Pledgor or in the Administrative Agent's own name, from time to time in the
Administrative Agent's discretion, for the purpose of carrying out the terms of
this Agreement, to take any and all appropriate action and to execute any and
all documents and instruments which may be necessary or desirable to accomplish
the purposes of this Agreement, including, without limitation, any financing
statements, endorsements, assignments or other instruments of transfer.

         (b) Each Pledgor hereby ratifies all that said attorneys shall lawfully
do or cause to be done pursuant to the power of attorney granted in paragraph
11(a). All powers, authorizations and agencies contained in this Agreement are
coupled with an interest and are irrevocable until this Agreement is terminated
and the security interests created hereby are released.

         12. DUTY OF ADMINISTRATIVE AGENT. The Administrative Agent's sole duty
with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the Code or otherwise,
shall be to deal with it in the same manner as the Administrative Agent deals
with similar securities and property for its own account, except that the
Administrative Agent shall have no obligation to invest funds held in any
Collateral Account and may hold the same as demand deposits. Neither the
Administrative Agent, any Lender nor
<PAGE>
                                                                               9

any of their respective directors, officers, employees or agents shall be liable
for failure to demand, collect or realize upon any of the Collateral or for any
delay in doing so or shall be under any obligation to sell or otherwise dispose
of any Collateral upon the request of any Pledgor or any other Person or to take
any other action whatsoever with regard to the Collateral or any part thereof.

         13. EXECUTION OF FINANCING STATEMENTS. Pursuant to Section 9-402 of the
Code, each Pledgor authorizes the Administrative Agent to file financing
statements with respect to the Collateral without the signature of such Pledgor
in such form and in such filing offices as the Administrative Agent reasonably
determines appropriate to perfect the security interests of the Administrative
Agent under this Agreement. A carbon, photographic or other reproduction of this
Agreement shall be sufficient as a financing statement for filing in any
jurisdiction.

         14. AUTHORITY OF ADMINISTRATIVE AGENT. Each Pledgor acknowledges that
the rights and responsibilities of the Administrative Agent under this Agreement
with respect to any action taken by the Administrative Agent or the exercise or
non-exercise by the Administrative Agent of any option, voting right, request,
judgment or other right or remedy provided for herein or resulting or arising
out of this Agreement shall, as between the Administrative Agent and the
Lenders, be governed by the Credit Agreement and by such other agreements with
respect thereto as may exist from time to time among them, but, as between the
Administrative Agent and the Pledgors, the Administrative Agent shall be
conclusively presumed to be acting as agent for the Lenders with full and valid
authority so to act or refrain from acting, and neither the Pledgors nor any
Issuer shall be under any obligation, or entitlement, to make any inquiry
respecting such authority.

         15. NOTICES. All notices, requests and demands to or upon the
Administrative Agent or the Pledgors to be effective shall be effected in the
manner provided for in subsection 11.2 of the Credit Agreement, addressed as
follows:

         (1) if to the Administrative Agent, at its address or transmission
number for notices provided in subsection 11.2 of the Credit Agreement; and

         (2) if to a Pledgor, at its address or transmission number for notices
set forth on Schedule 2 hereto. The Administrative Agent and the Pledgors may
change their addresses and transmission numbers for notices by notice in the
manner provided in this subsection 11.2 of the Credit Agreement.

         16. SEVERABILITY. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         17. AMENDMENTS IN WRITING; NO WAIVER; CUMULATIVE REMEDIES. (a) None of
the terms or provisions of this Agreement may be waived, amended, supplemented
or otherwise modified in accordance with subsection 11.01 of the Credit
Agreement.

         (b) Neither the Administrative Agent nor any Lender shall by any act
(except by a written instrument pursuant to paragraph 17(a) hereof), delay,
indulgence, omission or otherwise be deemed to have waived any right or remedy
hereunder or to have acquiesced in any Default or Event of Default or in any
breach of any of the terms and conditions hereof. No failure to exercise, nor
any delay in exercising, on the part of the Administrative Agent or any Lender,
any right, power or privilege hereunder shall operate as a waiver thereof. No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. A waiver by the Administrative Agent or any Lender of
any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which the Administrative Agent or such Lender would
otherwise have on any future occasion.

         (c) The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

         18. SECTION HEADINGS. The section headings used in this Agreement are
for convenience of reference only and are not to affect the construction hereof
or be taken into consideration in the interpretation hereof.

         19. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
successors and assigns of each Pledgor and shall inure to the benefit of the
Administrative Agent and the Lenders and their successors and assigns.

         20. GOVERNING LAW. This Agreement shall be governed by, and construed
and interpreted in accordance with, the law of the State of New York.

                        THE MERIDIAN RESOURCE CORPORATION
                   SHAREHOLDERS APPROVE SHELL TRANSACTIONS

      The Meridian Resource Corporation (NYSE:TMR) announced today that,
following approval of its shareholders, it consummated the previously announced
merger (the "Merger") of Louisiana Onshore Properties Inc., an indirect
subsidiary of Shell Oil Company ("Shell"), and LOPI Acquisition Corp., a
wholly-owned subsidiary of Meridian. Meridian also announced that, immediately
following consummation of the Merger, it completed a separate purchase (with the
Merger, the "Shell Transactions") of oil and gas property interests from a
subsidiary of Shell. Consummation of the Shell Transactions provides Meridian
with substantially all of Shell's and its direct and indirect subsidiaries'
onshore oil and gas property interests in south Louisiana, and access to
substantially all of Shell's and its direct and indirect subsidiaries' 2-D and
3-D seismic data covering onshore south Louisiana. In connection with the
Merger, affiliates of Shell received a 39.9% interest in the Company, assuming
exercise of all outstanding options and warrants, comprised of 12,082,030 shares
of common stock and shares of a new series of preferred stock convertible into
12,837,428 shares of common stock. Meridian paid $42.5 million in connection
with the separate acquisition of oil and gas property interests, subject to
adjustment for production, expenses and other items since October 1, 1997.

      Joe Reeves, Chairman and CEO of Meridian, stated "We are very excited
about this new relationship with Shell. The addition of the oil and gas property
interests acquired in the Shell Transactions significantly strengthens the
Company's presence and operating leverage in the south Louisiana oil and gas
producing region."

      Transition of the operations of the properties acquired in the Shell
Transactions and analysis of the extensive 3-D and 2-D seismic data began with
the execution of a Transition Management Agreement on May 21, 1998.
Exploration/exploitation activities on the Shell properties have resulted in
field production increases of approximately 13 MMCFe/D plus two discoveries, as
follows:

      o     On May 15, 1998, Meridian, as Operator and 25% working interest
            owner of the West Gueydan prospect, completed the Anna Belle Bourque
            #1, in the Marg Howei sand at a depth of 12,500 feet. The well was
            tested at 3,377 MCF/D, 218 BC/D and 62 BW/D through a 14/64" choke
            at 3,520 psi FTP. Two additional wells are planned for the West
            Gueydan prospect in 1998, including the Vermillion Parish School
            Board No. 1 well, which currently is drilling at 10,002 feet with a
            planned total depth of 15,700 feet.

      o     On June 29, 1998, Meridian, as Operator and 100% working interest
            owner, logged the Myles Salt No. 32 at a total depth of 7,440 feet.
            Electric log analysis indicates the presence of 551 feet of gross
            pay. Two development wells are currently planned following
            completion of the No. 32 well.

      Meridian also announced that the voting on the proposal to increase
Meridian's authorized shares of common stock from 100,000,000 to 200,000,000
shares was deferred to give shareholders additional time to vote on the
proposal. The Special Meeting of Shareholders will reconvene on July 20, 1998,
at 9:00 a.m., at Meridian's offices to complete voting on such proposal.

      The Meridian Resource Corporation is an independent oil and natural gas
company engaged in the exploration and development of oil and natural gas
properties utilizing 3-D seismic technology, primarily in south Louisiana,
southeast Texas and offshore Gulf of Mexico. Meridian's offices are located in
Houston, Texas and its common stock is traded on the New York Stock Exchange
under the symbol "TMR". For additional information, visit our website at

      Certain of the foregoing statements may be deemed "forward-looking
statements" within the meaning of the Securities Exchange Act of 1934. Although
Meridian believes that the expectations reflected in such forward-looking
statements are reasonable, there can be no assurance that such expectations will
prove to have been correct. Certain risks and uncertainties inherent in
Meridian's business are set forth in Meridian's filings with the Securities and
Exchange Commission. These risks include (i) the continued production from
existing wells at their current or projected levels, (ii) price changes for oil
and gas, (iii) the ability of the Company to successfully complete those wells
that have been logged and reflect potential production, (iv) the ability of the
Company to successfully complete and produce those reserves scheduled as
"non-producing" or "undeveloped", (v) the ability of the Company to acquire
leases and timely drill its exploratory prospects, (vi) risks regarding
estimates of reserves, (vii) production risks, (viii) governmental regulations
and (ix) general risks regarding the exploration for, and production of, oil and
gas reserves, including uncertainties with respect to preliminary logging and
well tests.
