ITEM 5.  OTHER EVENTS.

         On July 3, 1997, The Meridian Resource Corporation, a Texas
corporation (the "Company"), entered into an Agreement and Plan of Merger (the
"Merger Agreement") with a wholly owned subsidiary of the Company ("Sub") and
Cairn Energy USA, Inc., a Delaware corporation ("Cairn"), providing for the
acquisition by the Company of Cairn pursuant to an expected tax free merger
(the "Merger") in which the stockholders of Cairn will receive 1.08 shares of
the Company's common stock, $.01 par value ("Company Common Stock"), in
exchange for each outstanding share of Cairn common stock, $.01 par value
("Cairn Common Stock").  Based on the number of shares of Cairn Common Stock
outstanding as of June 30, 1997, a total of approximately 18.9 million shares of
Company Common Stock would be issued in the Merger.

         The Merger is subject to various conditions, including the receipt of
all required regulatory approvals and the expiration or termination of all
waiting periods (and extensions thereof) under the Hart-Scott-Rodino Act.
Although there can be no assurance that the Merger will close, the Company
currently anticipates that the acquisition will be consummated shortly after
the receipt of such regulatory approvals and the approval of the Merger by the
stockholders of the Company and Cairn.

                                  ARTICLE III

                              CONVERSION OF SHARES

         SECTION 3.1      Effect Of Merger on Capital Stock.  At the Effective
Time, by virtue of the Merger and without any action on the part of any holder
of any capital stock of the Company,  Parent or Sub:

         (a)     Cancellation of Certain Company Common Stock.  Each share of
Company Common Stock, if any, that is owned by Parent or Sub or any Subsidiary
of Parent or held in the treasury of the Company shall be canceled and cease to
exist and no capital stock of Parent or other consideration shall be delivered
in exchange therefor.

         (b)     Conversion of Company Common Stock.  Each issued and
outstanding share of Company Common Stock (other than shares of Company Common
Stock canceled pursuant to Section 3.1(a)) shall be converted into 1.08 shares
(the "Conversion Ratio") of duly authorized, validly issued, fully paid and
nonassessable common stock, par value $.01 per share, of the Parent ("Parent
Common Stock").  Upon such conversion, all such shares of  Company Common Stock
shall be canceled and cease to exist, and the holder of a certificate
representing such shares shall cease to have any rights with respect thereto,
except the right to receive the number of whole shares of Parent Common Stock
to be issued in consideration therefor and any cash in lieu of fractional
shares of Parent Common Stock upon the surrender of such certificate in
accordance with Section 3.2.





                                       9
<PAGE>   10
         (c)     Treatment of Common Stock of Sub.  Each issued and outstanding
share of common stock, par value $.01 per share, of Sub shall be converted into
one fully paid and nonassessable share of common stock, par value $.01 per
share, of the Surviving Corporation.

         SECTION 3.2      Exchange of Certificates.

         (a)     Deposit with Exchange Agent.  As soon as practicable after the
Effective Time, Parent shall deposit with a bank or trust company mutually
agreeable to Parent and the Company (the "Exchange Agent") certificates
representing shares of Parent Common Stock required to effect the conversions
referred to in Section 3.1(b).

         (b)     Exchange Procedures.  As soon as practicable after the
Effective Time, the Exchange Agent shall mail to each holder of record of a
certificate or certificates that, immediately prior to the Effective Time,
represented outstanding shares of Company Common Stock (the "Certificates")
that were converted (collectively, the "Converted Shares") into shares of
Parent Common Stock pursuant to Section 3.1(b), (i) a form of letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to any Certificate shall pass, only upon actual delivery of such
Certificate to the Exchange Agent) and (ii) instructions for use in effecting
the surrender of Certificates in exchange for certificates representing shares
of Parent Common Stock.  Upon surrender of a Certificate to the Exchange Agent
(or to such other agent or agents as may be appointed by agreement of Parent
and the Company), together with a duly executed letter of transmittal and such
other documents as the Exchange Agent shall require, the holder of such
Certificate shall be entitled to receive in exchange therefor a certificate
representing the number of whole shares of Parent Common Stock that such holder
has the right to receive pursuant to the provisions of this Article III.  In
the event of a transfer of ownership of Converted Shares that is not registered
in the transfer records of the Company, a certificate representing the proper
number of shares of Parent Common Stock may be issued to the transferee if the
Certificate representing such Converted Shares is presented to the Exchange
Agent, accompanied by all documents required to evidence and effect such
transfer and by evidence satisfactory to the Exchange Agent that any applicable
stock transfer taxes have been paid.  If any Certificate shall have been lost,
stolen, mislaid or destroyed, then upon receipt of (x) an affidavit of that
fact from the holder claiming such Certificate to be lost, mislaid, stolen or
destroyed, (y) such bond, security or indemnity, as Parent or the Exchange
Agent may reasonably require, and (z) any other documentation necessary to
evidence and effect the bona fide exchange thereof, the Exchange Agent shall
issue to such holder a certificate representing the number of shares of Parent
Common Stock into which the shares represented by such lost, stolen, mislaid or
destroyed Certificate shall have been converted.  Until surrendered as
contemplated by this Section 3.2, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender a certificate representing shares of Parent Common Stock and cash in
lieu of any fractional shares of Parent Common Stock as contemplated by this
Section 3.2.

         (c)     Distributions with Respect to Unexchanged Shares.  No
dividends or other distributions declared or made after the Effective Time with
respect to Parent Common Stock with a record date after the Effective Time
shall be paid to the holder of any unsurrendered Certificate with respect to
the shares of Parent Common Stock represented thereby, and no cash payment in





                                       10
<PAGE>   11
lieu of fractional shares shall be made to any such holder pursuant to Section
3.2(d), until the holder of record of such Certificate shall surrender such
Certificate as contemplated by Section 3.2(b). Subject to the effect of
unclaimed property, escheat and other applicable laws, following surrender of
any such Certificate there shall be paid to the holder of the certificates
representing whole shares of Parent Common Stock issued in exchange therefor,
without interest, (i) at the time of such surrender or as soon thereafter as
may be practicable, the amount of any cash payable in lieu of a fractional
share of Parent Common Stock to which such holder is entitled pursuant to
Section 3.2(d) and the amount of dividends or other distributions with a record
date after the Effective Time theretofore paid with respect to such whole
number of shares of Parent Common Stock, and (ii) at the appropriate payment
date, the amount of dividends or other distributions with a record date after
the Effective Time but prior to surrender and a payment date subsequent to
surrender payable with respect to such whole number of shares of Parent Common
Stock.

         (d)     No Fractional Securities.  No certificates or scrip
representing fractional shares of Parent Common Stock shall be issued upon the
surrender for exchange of Certificates, and such fractional share interests
will not entitle the owner thereof to vote or to any rights of a stockholder of
Parent.  In lieu of any such fractional shares, each holder of shares of
Company Common Stock who would otherwise have been entitled to receive a
fraction of a share of Parent Common Stock  (after taking into account all
shares of Company Common Stock then held of record by such holder) shall
receive cash (without interest) in an amount equal to the product of such
fractional part multiplied by the average of the daily closing price of Parent
Common Stock, rounded to four decimal places, as reported under New York Stock
Exchange in The Wall Street Journal for each of the first 20 consecutive days
on which the New York Stock Exchange is open for trading in the period
commencing 20 trading days prior to the Closing Date.

         (e)     Closing of Transfer Books.  From and after the Effective Time,
the stock transfer books of the Company shall be closed and no transfer of any
Company Common Stock shall thereafter be made.  If after the Effective Time any
certificates evidencing shares of Company Common Stock are presented to the
Parent's transfer agent for registration of transfer, they shall be canceled
and exchanged for certificates representing the number of whole shares of
Parent Common Stock and the cash amount, if any, determined in accordance with
this Article III.

         (f)     Termination of Duties of Exchange Agent.  Any certificates
representing Parent  Common Stock deposited with the Exchange Agent pursuant to
Section 3.2(a) and not exchanged within one year after the Effective Time
pursuant to this Section 3.2 shall be returned by the Exchange Agent to Parent,
which shall thereafter act as Exchange Agent.  All funds held by the Exchange
Agent for payment to the holders of unsurrendered Certificates and unclaimed at
the end of one year from the Effective Time shall be returned to Parent
whereupon any holder of unsurrendered Certificates shall look as a general
unsecured creditor only to Parent for payment of any funds to which such holder
may be entitled, subject to applicable law.  None of Parent, the Company or the
Surviving Corporation shall be liable to any person for such shares or funds
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.





                                       11
<PAGE>   12
         SECTION 3.3      Adjustments to Prevent Dilution.  Subject to the
requirements of Article VIII hereof, in the event that prior to the Effective
Time there is a change in the number of issued and outstanding shares of Parent
Common Stock or Company Common Stock, as the case may be, as a result of a
reclassification, subdivision, recapitalization, combination, exchange, stock
split (including reverse stock split), stock dividend or distribution or other
similar transaction, the Conversion Ratio shall be equitably adjusted to
eliminate the effects of such event, and all references to the Conversion Ratio
in this Agreement shall be deemed to be to the Conversion Ratio as so adjusted.

         SECTION 3.4      Further Assurances.  At and after the Effective Time,
the officers and directors of the Surviving Corporation will be authorized to
execute and deliver, in the name and on behalf of the Company or Sub, any
deeds, bills of sale, assignments or assurances and to take and do, in the name
and on behalf of the Company or Sub, any other actions and things to vest,
perfect or conform of record or otherwise in the Surviving Corporation any and
all right, title and interest in, to and under any of the rights, properties or
assets acquired or to be acquired by the Surviving Corporation as a result of,
or in connection with, the Merger.

the last of the conditions set forth in Article X is fulfilled or waived, or at
such other time and date and place as Parent and the Company shall mutually
agree (the "Closing Date").

officer or director of Parent or any of its Subsidiaries (collectively, the

Benefit Plan or other retirement plan or arrangement, and no fact or event
exists that could reasonably be expected to give rise to any such liability.
The aggregate accumulated benefit obligations of any Parent Benefit Plan

could give rise to liability under such Act; and (vii) Parent and its
Subsidiaries are in compliance with all applicable agreements, contracts and
policies relating to employment, employment practices, wages, hours and terms
and conditions of employment of the employees, except where the failure to be
in compliance with each such agreement, contract and policy would not, either
individually or in the aggregate, have a Parent Material Adverse Effect.

         SECTION 5.11     Environmental Protection.  Except as disclosed in the
Parent SEC Reports and except as would not, individually or in the aggregate,
be reasonably expected to result in a  Parent Material Adverse Effect, (i)

connection with the preparation of the oil and gas reserve engineering report
concerning the Oil and Gas Interests of Parent and its Subsidiaries as of
December 31, 1996 reviewed by Ryder Scott Petroleum Engineers (the "Parent
Engineering Report") was (at the time supplied or as modified or amended prior
to the issuance of the Parent Engineering Report) true and correct in all
material respects.  For purposes of this Agreement "Oil and Gas Interests"
means, when used with respect to Parent and each of its Subsidiaries or the
Company, as the case may be, direct and indirect interests in and rights with
respect to oil, gas, helium, carbon dioxide, mineral, and related properties
and assets of any kind and nature, direct or indirect, including leasehold,

other nonworking interests, and nonoperating interests; all interests in and

(including tanks, tank batteries, pipelines, and gathering systems), pumps,
water plants, electric plants, gasoline and gas processing plants, refineries,
and other tangible personal property and fixtures associated with, appurtenant

and gas industry on a nationwide basis, there has been no Parent Material
Adverse Change regarding the matters addressed in the Parent Engineering

and has been continuously since December 31, 1995, insured in such amounts and
against such risks and losses as are customary for companies conducting the
respective businesses conducted by Parent and its Subsidiaries during such time
period.  Neither Parent nor any of its Subsidiaries has received any notice of

other proceeding (including, without limitation, tax, environmental or
development demands proceedings) is pending, or to the best of Parent's
knowledge threatened, which might result in loss of title to any of Parent's
Major Oil and Gas Interests.  Parent shall promptly notify the Company of any
such proceeding which may arise or be threatened prior to the Closing.  No
action, suit or proceeding is currently pending to which Parent is a party or
to which any of Parent's assets are subject which relates to the ownership or

Title to all of Parent's and Parent's Subsidiaries will have as of The Closing
Date, Defensible Title to all of Parent's Subsidiaries', Major Oil and Gas
Interests except for such defects in Parent's and its Subsidiaries' Defensible
Title that will not, individually or in the aggregate, affect the aggregate
value of such Major Oil and Gas Interests by an amount in excess of $1 million.

         (b)     All royalties, rentals, Pugh clause payments, shut-in gas
payments and other payments due with respect to Parent's and its Subsidiaries'
Major Oil and Gas Interests have been properly and timely paid, except (i) for
payments held in suspense for title or other reasons which are customary in the
industry and which will not result in grounds for cancellation of Parent's or
its Subsidiaries' rights in such Major Oil and Gas Interests and (ii) such
failures as would not have a Parent Material Adverse Effect.

         (c)     Except for such defaults that would not result in a Parent
Material Adverse Effect,  neither Parent nor any of its Subsidiaries is in
default (and there exists no event or circumstance which with notice or the
passage of time or both could constitute a default by Parent or its
Subsidiaries) under the terms of any leases, farmout agreements or other
contracts or agreements respecting Parent's or its Subsidiaries' Major Oil and
Gas Interests which could (i) interfere in any material respect with the
operation or use thereof, (ii) prevent Parent or its Subsidiaries from
receiving the proceeds of production attributable to their interest therein,
(iii) result in a cancellation of Parent's or Subsidiaries' interest therein,
or (iv) impair the value of parent's or Subsidiaries' interest therein.

         SECTION 5.18     Material Contracts and Agreements.

         (a)     All material contracts of Parent or its Subsidiaries have been
included in the Parent SEC Reports, except for those contracts not required to
be filed pursuant to the rules and regulations of the SEC.

         (b)     Section 5.18 of the Parent Disclosure Schedule sets forth a

ending December 31, 1997 and which have not previously been included as
exhibits in the Parent SEC Reports.

         SECTION 5.19     Opinion of Financial Advisor.  Parent has received

<PAGE>   22
         SECTION 5.20     Accounting Matters.  To the best of Parent's
knowledge, neither the Parent nor any of its Affiliates has through the date of
this Agreement taken or agreed to take any action that (without giving effect
to any action taken or agreed to be taken by the Company or any of its
affiliates) would prevent the Parent from accounting for the business
combination to be effected by the Merger as a pooling of interest.

         SECTION 5.21     State Takeover Statutes; Absence of Supermajority
Provision.  Parent has taken all action to assure that no state takeover
statute or similar statute or regulation, shall apply to the Merger or any of
the other transactions contemplated hereby.  Except for Parent Stockholders'
Approval, no other stockholder action on the part of Parent is required for
approval of the Merger, this Agreement and the transactions contemplated
hereby.  No provisions of Parent's Articles of Incorporation or By-laws or
other governing instruments of its subsidiaries or the terms of any rights plan
or other takeover defense mechanism of Parent would, directly or indirectly,
restrict or impair the ability of the Parent or the Company to consummate the
Merger nor will any such provisions restrict or impair the ability of the
stockholders of the Company to exercise the same rights to vote or otherwise
exercise the same rights as the other stockholders of Parent in the event that
the stockholders of the Company were to acquire securities of Parent.

         of the Company, its Joint Ventures have all permits, licenses,

         SECTION 6.10     Employee Matters.

         (a)     Benefit Plans.  With respect to all the employee benefit plans

give rise to any such liability.  The aggregate accumulated benefit obligations
of any Company  Benefit Plan subject to Title IV of ERISA do not exceed the
fair market value of the assets of such Company Benefit Plan.  Except as set
forth in Schedule 6.10(a) of the Company DISCLOSURE SCHEDULE, neither the

employment or severance agreement with any of its employees.

solicit cards from the employees of the Company or any of its Subsidiaries to
authorize representation by any labor organization; (v) neither the Company nor
any of its Subsidiaries is a party to, or is otherwise bound by, any consent
decree with any governmental authority relating to employees or employment
practices of the Company or any of its Subsidiaries; (vi) the Company and its
Subsidiaries have not incurred any liability under, and have complied in all
respects with, the Worker Adjustment Retraining Notification Act, and no fact
or event exists that could give rise to liability under such Act; and (vii) the

contracts and policies relating to employment, employment practices, wages,
hours and terms and conditions of employment of the employees, except where the
failure to be in compliance with each such agreement, contract and

<PAGE>   29
policy would not, either individually or in the aggregate, have a Company
Material Adverse Effect.

         SECTION 6.11     Environmental Matters.   Except  as disclosed in the

Environmental Laws and the terms and conditions of all applicable Environmental
Permits, (ii) there are no Environmental Claims against the Company or any of
its Subsidiaries, and (iii) no Hazardous Materials have been released,

estimates of oil and gas reserves attributable to the Oil and Gas Interests of
the Company in connection with the preparation of the oil and gas reserve
engineering report concerning the Oil and Gas Interests of the Company as of
December 31,  1996 (the "Company Engineering Report"), was (at the time
supplied or as modified or amended prior to the issuance of the Company
Engineering Report) true and correct in all material respects.  Except for
changes in classification or values of oil and gas reserve or property
interests that occurred in the ordinary course of business since December 31,
1996, and except for changes (including changes in commodity prices) generally
affecting the oil and gas industry on a nationwide basis, there has been no
Company Material Adverse Change  regarding the matters addressed in the Company
Engineering Report.

         SECTION 6.16     Ownership of Parent Common Stock. The Company does
not "beneficially own" (as such term is defined in Rule 13d-3 under the
Exchange Act) any shares of Parent Common Stock.

         SECTION 6.17     No Loss of Title to Interests.  No suit, action or
other proceeding (including, without limitation, tax, environmental or
development demands proceedings) is pending, or to the best of the Company's
knowledge threatened, which might result in loss of title to any of the
Company's Major Oil and Gas Interests.  The Company shall promptly notify
Parent of any such proceeding which may arise or be threatened prior to the
Closing.  No action, suit or proceeding is currently pending to which the
Company is a party or to which any of the Company's assets are subject which
relates to the ownership or operations of the Company's Major Oil and Gas
Interests.

         SECTION 6.18     Title to Major Oil and Gas Interests.

         (a)     The Company has, or will have as of the Closing Date,
Defensible Title to all of the Company's and its Subsidiaries' Major Oil and
Gas Interests, except for such defects in the Company's and its Subsidiaries'
Defensible Title that will not individually or in the aggregate, affect the
value of such Major Oil and Gas Interests by an amount in excess of $1 million.

         (b)     All royalties, rentals, Pugh clause payments, shut-in gas
payments and other payments due with respect to Company's and its Subsidiaries'
Major Oil and Gas Interests have been properly and timely paid, except (i) for
payments held in suspense for title or other reasons which are customary in the
industry and which will not result in grounds for cancellation of Company's or
its Subsidiaries' rights in such Major Oil and Gas Interests and (ii) such
failures as would not have a Company Material Adverse Effect.

         (c)     Except for such defaults that would not result in a Company
Material Adverse Effect, neither the Company nor any of its Subsidiaries is in
default (and there exists no event or circumstance which with notice or the
passage of time or both could constitute a default by the Company or its
Subsidiaries) under the terms of any lease, farmout agreements or other
contracts or agreements respecting the Company's or its Subsidiaries' Major Oil
and Gas Interests which could (i) interfere in any material respect with the
operation or use thereof, (ii) prevent the Company or its Subsidiaries from
receiving the proceeds of production attributable to their interest therein,
(iii) result in cancellation of the Company's interest therein, or (iv) impair

         SECTION 6.19     Material Contracts and Agreements.

         (a)     All material contracts of the Company or its Subsidiaries have

                                       30
<PAGE>   31
party or by which the Company or any of its Subsidiaries or any of their
respective assets is bound which would be required to be filed as exhibits to

and which have not previously been included as exhibits in the Company SEC
Reports.

         SECTION 6.20     Accounting Matters.  To the best of its knowledge,
neither the Company nor any of its affiliates, has through the date of this
Agreement taken or agreed to take any action that (without giving effect to any
action taken or agreed to be taken by Parent or any of its affiliates) would
present Parent from accounting for the business combination to be effected by
the Merger as a pooling of interests.

         SECTION 6.21     State Takeover Statutes; Absence of Supermajority
Provision.  The Company has taken all action to assure that no state takeover
statute or similar statute or regulation, including, without limitation Section
203 of the DGCL, shall apply to the Merger or any of the other transactions
contemplated hereby.  Except for Company Stockholders' Approval, no other
stockholder action on the part of the Company is required for approval of the
Merger, this Agreement and the transactions contemplated hereby.  No provisions
of the Company's Certificate of Incorporation or By-laws or other governing
instruments of its subsidiaries or the terms of any rights plan or other
takeover defense mechanism of the Company would, directly or indirectly,
restrict or impair the ability of Parent to vote, or otherwise to exercise the
rights of a stockholder with respect to, securities of the Company and its
subsidiaries that may be acquired or controlled by Parent or permit any
stockholder to acquire securities of the Company on a basis not available to
Parent in the event that Parent were to acquire securities of the Company.

                                  ARTICLE VII

                  REPRESENTATIONS AND WARRANTIES REGARDING SUB

         Parent and Sub jointly and severally represent and warrant to the
Company as follows:

         SECTION 7.1      Organization and Standing.  Sub is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware.  Sub was organized solely for the purpose of acquiring the Company
and engaging in the transactions contemplated by this Agreement and has not
engaged in any business since it was incorporated which is not in connection
with the Merger and this Agreement.

         SECTION 7.2      Capital Structure.  The authorized capital stock of
Sub consists of 1,000 shares of common stock, par value $0.01 per share, all of
which are validly issued and outstanding, fully paid and nonassessable, free of
preemptive rights and are owned by Parent free and clear of all liens, claims
and encumbrances.

         SECTION 7.3      Authority; Non-Contravention.  Sub has all requisite
power and authority to enter into this Agreement and to consummate the Merger
and the other transactions contemplated hereby.  The execution and delivery of
this Agreement by Sub, the performance by Sub of its obligations hereunder and
the consummation of the transactions contemplated hereby





                                       31
<PAGE>   32
have been duly authorized by its Board of Directors and Parent as its sole
stockholder, and, except for the corporate filings required by state law, no
other corporate proceedings on the part of Sub are necessary to authorize this
Agreement and the Merger and the other transactions contemplated hereby.  This
Agreement has been duly and validly executed and delivered by Sub and, assuming
the due authorization, execution and delivery hereof by the Company,
constitutes a valid and binding obligation of Sub enforceable against Sub in
accordance with its terms, except to the extent enforceability may be limited
by applicable bankruptcy, insolvency, reorganization, fraudulent conveyance or
other similar laws affecting the enforcement of creditors' rights generally,
and except that the availability of equitable remedies, including specific
performance, may be subject to the discretion of any court before which any
proceedings may be brought.  The execution and delivery of this Agreement do
not, and the consummation of the transactions contemplated hereby and
compliance with the provisions hereof will not, violate, conflict with or
result in a breach of any provision of, or constitute a default (with or
without notice or lapse of time, or both) under, or result in the termination
of, or accelerate the performance required by, or result in a right of
termination, cancellation or acceleration of any obligation or the loss of a
material benefit under, or result in the creation of any lien, security
interest, charge or encumbrance upon any of the properties or assets of Sub
under, any provisions of (i) the Certificate of Incorporation or Bylaws (true
and complete copies of which as of the date hereof have been delivered to the
Company) of Sub, (ii) any loan or credit agreement, note, bond, mortgage,
indenture, lease or other agreement, instrument, permit, concession, franchise
or license applicable to Sub or (iii) any judgment, order, decree, statute,
law, ordinance, rule or regulation applicable to Sub or any of its properties
or assets, other than, in the case of clauses (ii) or (iii), any such
conflicts, violations, defaults, rights, losses, liens, security interests,
charges or encumbrance that, individually or in the aggregate, would not have a
Sub Material Adverse Effect, materially impair the ability of Sub to perform
its obligations hereunder or prevent the consummation of any of the
transactions contemplated hereby.

                                  ARTICLE VIII

                     CONDUCT OF BUSINESS PENDING THE MERGER

                                       33
<PAGE>   34

other party, which consent shall not be unreasonably withheld; provided,
however, that Parent and the Company may acquire Oil and Gas Interests in the
ordinary course of business consistent with prior practice.  Notwithstanding
the foregoing, except for acquisitions of Oil and  Gas Interests in the
ordinary course of business consistent with prior practice, in no event shall
any acquisition, merger, consolidation or purchase of any assets or business
from an Affiliate of Parent or its subsidiaries, or the Company or the

rights to indemnification existing as of the Effective Time in favor of the
current and former directors, officers and employees of the Company and its
Subsidiaries (at the Effective Time) (each an "Indemnified Party") as provided

in full force and effect.  After the Effective Time, Parent will consent to the
establishment by the Surviving Corporation and its Subsidiaries of such

         and assets to any person,

then and in each such case, proper provision shall be made so that such
successors and assigns shall assume the obligations set forth in this Section
9.5.

benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and his or her representatives.

         SECTION 9.6      DISCLOSURE SCHEDULEs.

         (a)     On or prior to the date of this Agreement, the Company shall

the transactions contemplated hereby and shall not issue any public
announcement or statement prior to consultation with the other party, except

The parties agree that the initial press release or releases to be issued in
connection with the execution of this Agreement shall be mutually agreed upon
prior to the issuance thereof.

         SECTION 9.8      Rule 145 Affiliates. Parent shall have received from
the Company a list of such Persons, if any, that Parent, after discussions with
counsel for the Company, believes may be "affiliates" of the Company, within
the meaning of Rule 145 of the SEC pursuant to the Securities Act

cause to be delivered to Parent on or prior to the Closing Date an undertaking
by each Affiliate in form satisfactory to Parent ("Affiliate Letters") that (i)
such Affiliate has no current plan or intention to sell, exchange or otherwise
dispose of the Parent Common Stock to be received by such Affiliate pursuant to
the Merger, (ii) no disposition will be made by such Affiliate of any Parent

registration under the Securities Act and (iv) such Affiliate agrees that
appropriate legends shall be placed upon the certificates evidencing ownership
of Parent Common Stock that such person receives as a result of the merger.

         SECTION 9.10     Stock Option and Bonus Plans.

         The following provisions shall apply to each stock option plan, stock
bonus plan and similar plans of the Company under which the delivery of Company

grant of awards or exercise of options (each a "Stock Plan", and all of which
are described in Section 9.10 of the Company DISCLOSURE SCHEDULE):

         (a)     The Company shall take such action as may be necessary so that
from and after the date hereof, except as set forth in the Company DISCLOSURE

                                       41
<PAGE>   42
options, or other rights shall be made under any Stock Plan, and after the

         (b)     In the event after the Effective Time outstanding options are
exercisable in shares of Parent Common Stock as described in 9.10(a), Parent
shall

                 (i)      to the extent required under applicable SEC rules,
         take all corporate action necessary or appropriate to obtain
         stockholder approval at an annual meeting selected by Parent with
         respect to such Stock Plan to the extent such approval is required to
         enable such Stock Plan to comply with Rule 16b-3 promulgated under the
         Exchange Act,

                 (ii)     reserve for issuance under such Stock Plan or
         otherwise provide a sufficient number of shares of Parent Common Stock
         for delivery upon exercise of options under such Stock Plan which are
         outstanding on the date hereof,

                 (iii)    as soon as practicable after the Effective Time, file
         one or more registration statements under the Securities Act with
         respect to the shares of Parent Common Stock issuable upon the
         exercise of currently outstanding options under such Stock Plan to the
         extent such filing is required under applicable law, and use its
         reasonable best efforts to maintain the effectiveness of such
         registration statement(s) (and the current status of the prospectuses
         contained therein or related thereto) so long as such options remain
         outstanding, and

                 (iv)     take such action as may be reasonably required to
         cause the shares of Parent Common Stock issuable upon the exercise of
         currently outstanding options under such Stock Plan to be approved for

or proposal that constitutes or is reasonably likely to lead to any Takeover
Proposal, or, in the event of any unsolicited Takeover Proposal, engage in
negotiations or provide any confidential information or data to any person
relating to any Takeover Proposal.  Without limiting the foregoing, it is
understood that any violation of the restrictions set forth in the preceding
sentence by any Representative of a party, whether or not such Person is
purporting to act on behalf of the Party or otherwise, shall be deemed to be a
material breach of this Agreement by that party.

         (b)     Parent and the Company shall notify the other orally and in
writing of any such inquiries, offers or Takeover Proposals (including, without
limitation, the terms and conditions of any such proposal and the identity of
the person making it) within 24 hours of the receipt thereof.

         unsolicited request therefor, furnish information, including
         non-public information, to any person or "group" (within the meaning

                 (D)      pursuant to Section 11.1(h)(ii) (board withdrawal of

                             -FOR IMMEDIATE RELEASE-

          THE MERIDIAN RESOURCE CORPORATION AND CAIRN ENERGY USA, INC.
                            ANNOUNCE PROPOSED MERGER



         Houston, Texas - July 7, 1997 - The Meridian Resource Corporation
(NYSE: TMR) and Cairn Energy USA, Inc. (NASDAQ:CEUS) today announced that they
have entered into a definitive merger agreement pursuant to which Cairn would be
merged with a subsidiary of TMR.

         The terms of the merger agreement provide for the exchange of 1.08
shares of TMR's Common Stock for each share of Cairn Common Stock in a
pooling-of-interests transaction that is expected to be tax free to both
companies. TMR would issue approximately 18.9 million shares of its common stock
having a value in excess of $234 million based on TMR's closing stock price of
$12 5/16 per share on July 3, 1997. The merger is expected to be accretive to
1997 per share cash flow and income, excluding one-time charges relating to
expenses associated with the merger.

         On a combined basis, at year-end 1996, both companies had proved
reserves of approximately 164 Bcfe with a pre-tax present value of future net
cash flows discounted at 10% of approximately $395 million. The merger 
combines TMR's experience in the application of 3-D seismic exploration in the
transition zone and onshore Gulf Coast region with Cairn's similar expertise and
attractive portfolio of offshore Gulf of Mexico drilling prospects.

         Joseph A. Reeves, Jr., Chairman of the Board and Chief Executive Office
of TMR, said, "The merger of TMR and Cairn will provide the new company with a
greater critical mass and additional exploration prospects, which, in turn, will
afford excellent opportunities for the shareholders of the combined company.
TMR's market capitalization will increase twofold to over $425 million with
proved reserves increasing approximately threefold, and the combined company
maintains a strong balance sheet. The merger is the extension and expansion of
high potential exploration opportunities for two growth-minded companies who are
leaders among the independent oil and gas companies in the development of 3-D
seismic exploration projects, both with outstanding track records (over 70%
combined). This fit of exploration philosophies, highly skilled technical and
professional staffs, timing of projects and future exploration activities will
provide a unique opportunity for


<PAGE>   2



growth for the combined company. I sincerely believe that both companies'
shareholders will recognize the benefits of this merger."


         Michael R. Gilbert, President and Chief Executive Officer of Cairn,
said, "The assets of Cairn and TMR are a natural strategic fit. Our shareholders
benefit from greater scale, increased financial strength and the participation
in a large pool of exciting exploration and development drilling opportunities."

         In addition, the companies believe that the merger is expected to
provide the following additional strategic benefits:

* Increased cash flow and a strong balance sheet with the financial flexibility
to fund the combined company's 1998 and 1999 capital expenditures.

* Expansion of TMR's core area of operations from the Texas and Louisiana
onshore Gulf Coast and transition zones to the offshore Outer Continental Shelf
of the Gulf of Mexico.

* Provide the combined company with more than 200 prospect opportunities
covering approximately 150,000 acres in the Texas and Louisiana onshore Gulf
Coast and transition zones to the offshore Outer Continental Shelf of the Gulf
of Mexico.

* Combine two technical leaders in the area of 3-D seismic exploration in the
Gulf Coast onshore and offshore region with a combined three-year exploration
success ratio utilizing 3-D seismic in excess of 70%.

* Increase the inventory of 3-D seismic data of the combined company to over
2,200 square miles of information.

* Provide both companies' shareholders with greater liquidity in their stock, a
substantially larger market capitalization and shareholder base.

         TMR is an independent oil and natural gas company engaged in the
exploration for and development of oil and natural gas properties utilizing 3-D
seismic technology, primarily in south Louisiana and southeast Texas. TMR is
headquartered in Houston, Texas.

         Cairn is engaged in the exploration for and the development and
production of crude oil and natural gas, principally in the Outer Continental
Shelf of the Gulf of Mexico. Cairn also has interests in properties in
Pennsylvania, Texas and other onshore areas.

         The merger is subject to certain conditions, including the approval of
the shareholders of both companies pursuant to a prospectus and joint proxy
statement to be filed with the Securities and Exchange Commission.

         Statements made in this press release that are forward-looking in
nature are intended to be "forward-looking statements" within the meaning of
Section 21E of the Securities Exchange Act of 1934. Such forward-looking
statements are intended to be identified by the words "believe", "expect",
"anticipate" and similar expressions. Although TMR and Cairn believe that the
expectations described in such forward-looking statements are reasonable, the
actual results of the combined company could differ materially from those
currently anticipated. Factors that could cause results to differ materially
include changes in industry conditions and demand and prices of oil and gas, the
timing of drilling of new prospects, the ability of TMR to successfully identify
and complete current prospects, variation in actual production results from that
estimated in existing reserve data, TMR's ability to achieve the strategic
benefits described above, the successful integration of Cairn's operations with
those of TMR, regulatory changes affecting exploration activities and higher
costs associated with drilling. These factors are more fully described in TMR's
and Cairn's filings under the Securities Exchange Act of 1934.
