ITEM 5.  OTHER EVENTS

      On June 19, 1997, Convest Energy Corporation ("Convest"), Edisto Resources
Corporation ("Edisto"), Forcenergy Inc ("Forcenergy") and a Forcenergy
subsidiary executed a definitive Agreement and Plan of Merger (the "Merger
Agreement") providing for Convest and Edisto to be merged into Forcenergy.

      Under the Merger Agreement, (a) each issued and outstanding share of
Convest Common Stock will be converted into the right to receive a fractional
interest in a share of Forcenergy Common Stock equal to $8.88 divided by the
Weighted Average Trading Price of Forcenergy Common Stock, and (b) each issued
and outstanding share of Edisto Common Stock will be converted into the right to
receive (i) $4.886 in cash and (ii) a fractional interest in a share of
Forcenergy Common Stock equal to $5.064 divided by the Weighted Average Trading
Price of Forcenergy Common Stock; PROVIDED, HOWEVER, that in no event shall the
Weighted Average Trading Price of Forecenergy Common Stock be less than $28.96
nor more than $34.96. The "Weighted Average Trading Price" of Forcenergy Common
Stock will be calculated by taking the average of the following daily
calculations for each of the ten trading days ending two trading days prior to
the closing date for the Merger: (i) grouping together all shares of Forcenergy
Common Stock traded on such day at the same trading price, (ii) multiplying the
aggregate number of shares in each price group by the trading price for such
group to calculate a product (the total sold shares value) for each group, (iii)
adding all of such products from each group, and (iv) dividing the resulting
total by the aggregate number of shares traded on such trading day. Cash will be
paid in lieu of fractional shares of Forcenergy Common Stock. The mergers are
expected to close in late August or early September.

      The majority shareholders of Convest and Edisto have agreed to vote their
respective shares in favor of the transaction thereby assuring the necessary
levels of shareholder approval. Edisto currently owns approximately 72% of the
outstanding shares of Common Stock of Convest, and has agreed in the Merger
Agreement to vote its shares of Convest Common Stock in favor of the
transaction. In addition, investment funds and accounts managed by TCW Special
Credits and Oaktree Capital Management, L.L.C., which hold slightly in excess of
51% of Edisto's Common Stock, have agreed to support the proposed merger by
their willingness to vote for the transaction. Such investment funds and
accounts also have contractually agreed not to sell 80% of the Forcenergy Common
Stock received in the transaction for a period of six months after the closing.

      the resulting

                                        9

      may be expended to effect any such redemptions may not exceed $2,300,000.

            (d)   EXCHANGES.

<PAGE>
      surrender thereof to the Exchange Agent, a certificate or certificates
      representing the number of whole shares of Parent Common Stock to which

      certificate which immediately prior to the Merger 3 Effective Time
      represented shares of Convest Common Stock (a "CONVEST CERTIFICATE") shall
      be entitled to receive in exchange therefor, upon surrender thereof to the
      Exchange Agent, a certificate or certificates representing the number of
      whole shares of Parent Common Stock to which such holder is entitled
      pursuant to Section 4(a)(ii)(A). Notwithstanding any other provision of
      this Agreement, (A) until holders or transferees of Edisto Certificates or
      Convest Certificates have surrendered them for exchange as provided
      herein, no dividends shall be paid with respect to any shares represented
      by such certificates and no payment for fractional shares shall be made
      and (B) without regard to when such Edisto Certificates or Convest
      Certificates are surrendered for exchange as provided herein, no interest
      shall be paid on any dividends or any payment for fractional shares. Upon
      surrender of an Edisto Certificate or a Convest Certificate, respectively,
      there shall be paid to the holder of such certificate the amount of any
      dividends which theretofore became payable, but which were not paid by
      reason of the foregoing, with respect to the number of whole shares of
      Parent Common Stock represented by the certificate or certificates issued
      upon such surrender.

                  (ii) If any certificate for shares of Parent Common Stock is
      to be issued in a name other than that in which the Edisto Certificate or
      Convest Certificate surrendered in exchange therefor is registered, it
      shall be a condition of such exchange that the person requesting such
      exchange shall pay any applicable transfer or other taxes required by
      reason of such issuance.

                  (iii) Promptly after the Merger 3 Effective Time, Parent shall
      make available to the Exchange Agent (A) the certificates representing
      shares of Parent Common Stock required to effect the exchanges referred to
      in paragraphs (d)(i) and (ii) above and (B) funds sufficient for the
      payment of the aggregate Merger 1 Cash Consideration required to effect
      the exchange referred to in paragraph (i) above and for payment of any
      fractional shares referred to in Section 4(e) (the "EXCHANGE FUND"), it
      being understood that any and all interest earned on funds made available
      to the Exchange Agent pursuant to this Agreement shall be for the account
      of, and shall remain the property of, Parent.

                  (iv) (A) Promptly after the Merger 3 Effective Time, but in no
            event later than ten business days, the Exchange Agent shall mail to
            each holder of record of an Edisto Certificate (x) a letter of
            transmittal (which shall specify that delivery shall be effected,
            and risk of loss and title to the Edisto Certificates shall pass,
            only upon actual delivery of the Edisto Certificates to the Exchange
            Agent) and (y) instructions for use in effecting the surrender of
            the Edisto Certificates in exchange for certificates representing
            shares of Parent Common Stock and Merger 1 Cash Consideration. Upon
            surrender of Edisto Certificates for cancellation to the Exchange
            Agent, together with a duly executed letter of transmittal and such
            other documents as the Exchange Agent shall reasonably require, the
            holder of such Edisto Certificates shall be entitled to receive in
            exchange therefor (1) a certificate representing that number of
            whole shares, if any, of Parent Common Stock into which the shares
            of Edisto Common Stock theretofore represented by the Edisto
            Certificates so surrendered shall have been converted pursuant to
            the provisions of Section 4(a)(i)(A)(x), and (2) the amount of
            Merger 1 Cash Consideration into which the number of shares of
            Edisto Common Stock previously represented by such Edisto
            Certificates so surrendered shall have been converted pursuant to
            the provisions of Section 4(a)(i)(A)(y), and the Edisto Certificates

                                       11
<PAGE>
            so surrendered shall be canceled. Notwithstanding the foregoing,
            neither the Exchange Agent nor any party hereto shall be liable to a
            holder of shares of Edisto Common Stock for any shares of Parent
            Common Stock or dividends or distributions thereon delivered to a
            public official pursuant to applicable abandoned property, escheat
            or similar laws.

                        (B) Promptly after the Merger 3 Effective Time, but in
            no event later than ten business days, the Exchange Agent shall mail
            to each holder of record of a Convest Certificate (x) a letter of
            transmittal (which shall specify that delivery shall be effected,
            and risk of loss and title to the Convest Certificates shall pass,
            only upon actual delivery of the Convest Certificates to the
            Exchange Agent) and (y) instructions for use in effecting the
            surrender of the Convest Certificates in exchange for certificates
            representing shares of Parent Common Stock. Upon surrender of
            Convest Certificates for cancellation to the Exchange Agent,
            together with a duly executed letter of transmittal and such other
            documents as the Exchange Agent shall reasonably require, the holder
            of such Convest Certificates shall be entitled to receive in
            exchange therefor a certificate representing that number of whole
            shares, if any, of Parent Common Stock into which the shares of
            Convest Common Stock theretofore represented by the Convest
            Certificates so surrendered shall have been converted pursuant to
            the provisions of Section 4(a)(ii)(A), and the Convest Certificates
            so surrendered shall be canceled. Notwithstanding the foregoing,
            neither the Exchange Agent nor any party hereto shall be liable to a
            holder of shares of Convest Common Stock for any shares of Parent
            Common Stock or dividends or distributions thereon delivered to a
            public official pursuant to applicable abandoned property, escheat
            or similar laws.

                  (v) Promptly following the date which is one year after the
      Closing Date, the Exchange Agent shall deliver to Parent all cash
      (including any remaining balance in the Exchange Fund), certificates
      (including any Parent Common Stock) and other documents in its possession
      relating to the transactions described in this Agreement, and the Exchange
      Agent's duties shall terminate. Thereafter, each holder of an Edisto
      Certificate or a Convest Certificate may surrender such certificate to
      Parent and (subject to applicable abandoned property, escheat and similar
      laws) receive in exchange therefor the Parent Common Stock and Merger 1
      Cash Consideration (if applicable), without any interest thereon. If
      outstanding Edisto Certificates or Convest Certificates are not
      surrendered prior to six years after the Merger 3 Effective Time (or, in
      any particular case, prior to such earlier date on which any Merger 1
      Consideration issuable in respect of such Edisto Certificates or Merger 3
      Consideration issued in respect of such Convest Certificates or the
      dividends and other distributions, if any, described below would otherwise
      escheat to or become the property of any governmental unit or agency), the
      Merger 1 Consideration issuable in respect of such Edisto Certificates or
      Merger 3 Consideration issuable in respect of such Convest Certificates,
      and the amount of dividends and other distributions, if any, which have
      become payable and which thereafter become payable thereon as provided
      herein shall, to the extent permitted by applicable law, become the
      property of Parent, free and clear of all claims or interest of any Person
      previously entitled thereto. Notwithstanding the foregoing, neither the
      Exchange Agent or the Parties shall be liable to a holder of shares of
      Edisto Common Stock or Convest Common Stock for any shares of Parent
      Common Stock or Merger 1 Cash Consideration delivered to a public official
      pursuant to applicable abandoned property, escheat or similar laws.

                  (vi) In the event any Edisto Certificate or Convest
      Certificate shall have been lost, stolen or destroyed, upon the making of
      an affidavit of that fact by the person claiming such Edisto Certificate
      or Convest Certificate to be lost, stolen or destroyed and, subject to the
      following sentence,

                                       12
<PAGE>
      Surviving Corporation 3 shall issue in exchange for such lost, stolen or
      destroyed Edisto Certificate or Convest Certificate the Merger 1
      Consideration or Merger 3 Consideration, respectively, deliverable in
      respect thereof determined in accordance with this Section 4. Surviving
      Corporation 3 may, in its discretion and as a condition precedent to the
      issuance thereof, require the owner of such lost, stolen or destroyed
      certificate to give such corporation such indemnity, bond or insurance as
      it may reasonably direct as protection against any claim that may be made
      against such corporation with respect to the certificate alleged to have
      been lost, stolen or destroyed.

            (e) NO FRACTIONAL SECURITIES. Notwithstanding any other provision of
this Agreement, no certificates or scrip for fractional shares of Parent Common
Stock shall be issued in the Mergers and no Parent Common Stock dividend, stock
split or interest shall relate to any fractional security, and such fractional
interests shall not entitle the owner thereof to vote or to any other rights of
a security holder. In lieu of any such fractional share, each holder of shares
of Edisto Common Stock or Convest Common Stock who would otherwise have been
entitled to receive a fraction of a share of Parent Common Stock upon surrender
of Edisto Certificates or Convest Certificates for exchange pursuant to this
Section 4 shall be entitled to receive from the Exchange Agent a cash payment
equal to such fraction multiplied by either (i) the Weighted Average Trading
Price, (ii) $34.96 or (iii) $28.96, depending on which of the foregoing prices
is used for the ratio calculations pursuant to Section 4(a).

            (f) CLOSING. The closing (the "CLOSING") of the transactions
contemplated by this Agreement shall take place at a location mutually agreeable
to Parent, Edisto and Convest as promptly as practicable following the date on
which the last of the conditions set forth in Section 9 is fulfilled or waived,
or at such other time and place as Parent, Edisto and Convest shall agree. The
date on which the Closing occurs is referred to in this Agreement as the
"CLOSING DATE."

            (g)   CLOSING OF TRANSFER BOOKS.

                  (i) EDISTO. At and after the Merger 1 Effective Time, holders
      of Edisto Certificates shall cease to have any rights as stockholders of
      Edisto, except for the right to receive shares of Parent Common Stock and
      Merger 1 Cash Consideration pursuant to Section 4(a)(i) and the right to
      receive cash for payment of fractional shares pursuant to Section 4(e). At
      the Merger 1 Effective Time, the stock transfer books of Edisto shall be
      closed and no transfer of shares of Edisto Common Stock which were
      outstanding immediately prior to the Merger 1 Effective Time shall
      thereafter be made. If, after the Merger 1 Effective Time, subject to the
      terms and conditions of this Agreement, Edisto Certificates formerly
      representing shares of Edisto Common Stock are presented to Parent, they
      shall be canceled and exchanged for shares of Parent Common Stock in
      accordance with this Section 4.

                  (ii) CONVEST. At and after the Merger 3 Effective Time,
      holders of Convest Certificates shall cease to have any rights as
      stockholders of Convest, except for the right to receive shares of Parent
      Common Stock pursuant to Section 4(a)(ii) and the right to receive cash
      for payment of fractional shares pursuant to Section 4(e). At the Merger 3
      Effective Time, the stock transfer books of Convest shall be closed and no
      transfer of shares of Convest Common Stock which were outstanding
      immediately prior to the Merger 2 Effective Time shall thereafter be made.
      If, after the Merger 3 Effective Time, subject to the terms and conditions
      of this Agreement, Convest Certificates formerly representing shares of
      Convest Common Stock are presented to Parent, they shall be canceled and
      exchanged for shares of Parent Common Stock in accordance with this
      Section 4.

                                       13
<PAGE>
            (h) APPRAISAL RIGHTS. Notwithstanding anything in this Agreement to
the contrary, in the event that appraisal rights are available in connection
with Merger 1 pursuant to Section 262 of the DGCL, shares of Edisto Common Stock
that are issued and outstanding immediately prior to the Merger 1 Effective Time
and that are held by Edisto Stockholders who did not vote in favor of Merger 1
and who comply with all of the relevant provisions of Section 262 of the DGCL
(the "Dissenting Shares") shall not be converted into or be exchangeable for the
right to receive the Merger 1 Consideration, unless and until such Edisto
Stockholders shall have failed to perfect or shall have effectively withdrawn or
lost such right, and such Edisto Stockholders' shares of Edisto Common Stock
shall thereupon be deemed to have been converted into and to have become
exchangeable for the right to receive, as of the Merger 1 Effective Time, the
Merger 1 Consideration without any interest thereon. Edisto shall give Parent
(i) prompt notice of any written demands for appraisal of shares of Edisto
Common Stock received by Edisto and (ii) the opportunity to direct all
negotiations and proceedings with respect to any such demands. Edisto shall not,
without the prior consent of Parent, voluntarily make any payment with respect
to, or settle or offer to settle, any such demands.

SECTION 5.  REPRESENTATIONS AND WARRANTIES OF THE SELLERS.

            Except for those matters included in the Sellers Disclosure
Schedule, which inclusion will not be deemed an admission by Sellers that any
such matter is material or has or would have a Material Adverse Effect or
represents a Material Adverse Change, each Seller represents and warrants to the
Purchaser as follows:

            (a) ORGANIZATION, QUALIFICATION, AND CORPORATE POWER. Each of the
Sellers and their respective Subsidiaries is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation. Set forth on the Sellers Disclosure Schedule is a list of all
Subsidiaries of each Seller, and a list of those jurisdictions where each of the
Sellers and their respective Subsidiaries are qualified to conduct business.
Each of the Sellers and its respective Subsidiaries is duly authorized to
conduct business and is in good standing under the laws of each jurisdiction
where such qualification is required, except for failures that would not have a
Material Adverse Effect. The Sellers Disclosure Schedule correctly sets forth
the name of each Subsidiary of each Seller, the jurisdiction of its
incorporation and the Persons owning its outstanding capital stock.

            (b)   CAPITALIZATION.

                  (i) (x) The entire authorized capital stock of Edisto
      consisted of 50,000,000 shares of Edisto Common Stock and 10,000,000
      shares of preferred stock, of which 14,138,274 shares (excluding treasury
      shares) of Edisto Common Stock and no shares of preferred stock were
      issued and outstanding as of June 16, 1997, and (y) the entire authorized
      capital stock of Convest consisted of 20,000,000 shares of Convest Common
      Stock and 5,000,000 shares of preferred stock, of which 10,544,411 shares
      (excluding treasury shares) of Convest Common Stock and no shares of
      preferred stock were issued and outstanding as of June 16, 1997. Edisto is
      the beneficial owner of 7,598,771 shares of Convest Common Stock (the
      "Shares"), free and clear of any liens, claims, options, charges or other
      encumbrances.

                  (ii) Except for employee and director stock options disclosed
      on Sellers Disclosure Schedule, there are no outstanding or authorized
      options, warrants, purchase rights, subscription rights, conversion
      rights, exchange rights, or other contracts or commitments that could
      require either Seller to issue, sell, or otherwise cause to become
      outstanding any of its capital stock or any other securities convertible
      into or evidencing the right to subscribe for any of its capital stock.

                                       14
<PAGE>
      There are no outstanding or authorized stock appreciation, phantom stock,
      profit participation, or similar rights with respect to either Seller. At
      and as of the Closing, neither Seller will be a party to any agreement
      relating to the registration under the Securities Act of shares of capital
      stock of such Seller or any successor entity. The Sellers Disclosure
      Schedule shall indicate, by holder, the shares of capital stock of each
      Seller subject to any options, warrants or similar rights, and the
      exercise price, expiration date and vesting period thereof.

            (c)   AUTHORIZATION OF TRANSACTION.

                  (i) Each Seller has corporate power and authority to execute
      and deliver this Agreement, and, subject to the Requisite Stockholder
      Approvals, to consummate the transactions contemplated hereby. The Board
      of Directors of Edisto, has approved this Agreement and Merger 1 in
      accordance with the applicable provisions of the DGCL and (A) recommended
      approval of this Agreement and Merger 1 by the Edisto Stockholders, and
      (B) duly and validly authorized the execution and delivery of this
      Agreement by Edisto and the consummation by Edisto of the transactions

      TBCA and (A) recommended approval of this Agreement and Merger 3 by the
      Convest Stockholders, and (B) duly and validly authorized the execution
      and delivery of this Agreement by Convest and the consummation by Convest
      of the transactions contemplated hereby. Except for the Requisite
      Stockholder Approvals, no other corporate proceedings on the part of
      either Seller are necessary to authorize this Agreement or to consummate
      the transactions so contemplated. This Agreement has been duly executed
      and delivered on behalf of each Seller and, subject to the Requisite
      Stockholder Approvals, constitutes the valid and legally binding
      obligation of each Seller, enforceable against each Seller in accordance
      with its terms and conditions, except that (A) such enforcement may be
      subject to bankruptcy, insolvency, reorganization, moratorium or other
      similar laws now or hereafter in effect relating to creditors' rights
      generally and (B) the remedy of specific performance and injunctive and
      other forms of equitable relief may be subject to equitable defenses and
      to the discretion of the court before which any proceeding therefor may be
      brought.

                  (ii) The only votes of Edisto Stockholders required to adopt
      the Agreement and approve Merger 1 are the affirmative vote of the holders
      of a majority of Edisto Common Stock pursuant to Section 216 of the DGCL,
      Edisto's Restated Certificate of Incorporation, as amended, and Section 5
      of Edisto's By-laws, represented in person or by proxy, at a stockholder
      meeting called by Edisto for the purpose of considering and voting upon
      the Agreement and Merger 1 or by written consent in lieu of a meeting
      pursuant to Section 228 of the DGCL and in accordance with Edisto's
      Restated Certificate of Incorporation, as amended; the only votes of
      Convest Stockholders required to adopt the Agreement and approve Merger 3
      are the affirmative vote of the holders of two-thirds of the outstanding
      shares of Convest Common Stock pursuant to Article XII.A. of Convest's
      Articles of Incorporation and Article 5.03 of the TBCA, represented in
      person or by proxy, at a stockholder meeting called by Convest for the
      purpose of considering and voting upon the Agreement and Merger 3 or by
      written consent in lieu of a meeting pursuant to Article XII.B. of
      Convest's Articles of Incorporation and Article 9.10.A. of the TBCA
      (collectively, the "REQUISITE STOCKHOLDER APPROVALS"). The Convest
      Stockholders will not have any appraisal or dissenter's rights under the
      TBCA as a result of the transactions contemplated by this Agreement.

            (d) NON-CONTRAVENTION. The execution and delivery of this Agreement
by each Seller do not violate, conflict with or result in a breach of any
provision of, or constitute a default (or an event which,

                                       15
<PAGE>
with notice or lapse of time or both, would constitute a default) under, or
result in the termination of, or accelerate the performance required by, or
result in a right of termination or acceleration under, or result in the
creation of any lien, security interest, charge, encumbrance or preferential
right to purchase upon any of the properties or assets of either Seller or any
of its respective Subsidiaries under any of the terms, conditions or provisions
of (i) the respective charters or by-laws of either Seller or any of its
respective Subsidiaries, (ii) any statute, law, ordinance, rule, regulation,
judgment, decree, order, injunction, writ, permit or license of any court or
governmental authority applicable to either Seller or any of its respective
Subsidiaries or any of their respective properties or assets or (iii) any note,
bond, mortgage, indenture, deed of trust, license, franchise, permit,
concession, contract, lease or other instrument, obligation or agreement of any
kind to which either Seller or any of its respective Subsidiaries is now a party
or by which either Seller or any of its respective Subsidiaries or any of their
respective properties or assets may be bound or affected. The consummation by
the Sellers of the transactions contemplated hereby will not result in any
violation, conflict, breach, termination, acceleration or creation of liens or
preferential right to purchase under any of the terms, conditions or provisions
described in clauses (i) through (iii) of the preceding sentence, subject (x) in
the case of the terms, conditions or provisions described in clause (ii) above,
to obtaining (prior to the Merger 1 Effective Time) the Requisite Stockholder
Approvals and (y) in the case of the terms, conditions or provisions described
in clause (iii) above, to obtaining (prior to the Merger 1 Effective Time)
consents required from commercial lenders, lessors or other third parties as
specified on the Sellers Disclosure Schedule. Excluded from the foregoing
sentences of this paragraph (d), insofar as they apply to the terms, conditions
or provisions described in clauses (ii) and (iii) of the first sentence of this
paragraph (d), are such violations, conflicts, breaches, defaults, terminations,
accelerations or creations of liens, security interests, charges or encumbrances
that would not, in the aggregate, have a Material Adverse Effect.

            (e) APPROVALS. Except for (i) the filing of the Joint Proxy
Statement/Prospectus with the SEC pursuant to the Exchange Act and the
Securities Act, and the declaration of the effectiveness thereof by the SEC and
any filings with various state blue sky authorities and, (ii) the making of the
Merger Filings with the Secretaries of State of the States of Delaware and Texas
in connection with the Mergers (the filings and approvals referred to in clauses
(i) and (ii) are collectively referred to as the "SELLERS REQUIRED STATUTORY
APPROVALS"), no declaration, filing or registration with, or notice to, or
authorization, consent or approval of, any governmental or regulatory body or
authority is necessary for the execution and delivery of this Agreement by
either Seller or the consummation by either Seller of the transactions
contemplated hereby, including pursuant to the HSR Act, other than such
declarations, filings, registrations, notices, authorizations, consents or
approvals which, if not made or obtained, as the case may be, would not, in the
aggregate, have a Material Adverse Effect.

            (f) REPORTS AND FINANCIAL STATEMENTS. Each Seller has filed with the
SEC all forms, statements, reports and documents (including all exhibits,
post-effective amendments and supplements thereto) required to be filed by it
under each of the Securities Act, the Exchange Act and the respective rules and
regulations thereunder, all of which, as amended if applicable, complied when
filed in all material respects with all applicable requirements of the
appropriate act and the rules and regulations thereunder. Each Seller has
previously delivered to Parent copies (including all exhibits, post-effective
amendments and supplements thereto) of its (a) Annual Reports on Form 10-K for
the fiscal year ended December 31, 1996 and for the two immediately preceding
fiscal years, as filed with the SEC, (b) proxy and information statements

documents referred to in clauses (a), (b) and (c) filed prior to the date hereof
are collectively referred to as the "SELLERS SEC REPORTS"). The Sellers SEC
Reports are identified on the Sellers Disclosure Schedule. As of their
respective dates, the Sellers SEC

                                       16
<PAGE>
Reports did not contain any untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The audited consolidated financial statements and
unaudited interim consolidated financial statements of each Seller included in
such reports (collectively, the "SELLERS FINANCIAL STATEMENTS") have been
prepared in accordance with GAAP applied on a consistent basis (except as may be
indicated therein or in the notes thereto) and fairly present the financial
position of each Seller and their respective Subsidiaries as of the dates
thereof and the results of their operations and changes in financial position
for the periods then ended, subject, in the case of the unaudited interim
financial statements, to normal year-end and audit adjustments and any other
adjustments described therein.

            (g) ABSENCE OF UNDISCLOSED LIABILITIES. Except as disclosed in the
Sellers SEC Reports or the Sellers Disclosure Schedule, neither Seller nor any

or otherwise) of any nature, except liabilities, obligations or contingencies
which: (i) are accrued or reserved against in the Sellers Financial Statements
or reflected in the notes thereto, (ii) would not, in the aggregate, have a
Material Adverse Effect, (iii) have been discharged or paid in full prior to the
date hereof, or (iv) are of a nature not required to be reflected in the
consolidated financial statements of either Seller and their respective
Subsidiaries prepared in accordance with GAAP consistently applied and which
were incurred in the Ordinary Course of Business.

            (h) ABSENCE OF CERTAIN CHANGES OR EVENTS. Since the date of the most
recent Sellers SEC Report for each Seller that contains consolidated financial
statements of such Seller, there has not been any Material Adverse Change.

            (i) LITIGATION. Except as disclosed in the Sellers SEC Reports or in
the Sellers Disclosure Schedule, there are no claims, suits, actions or
proceedings pending or, to the knowledge of either Seller, threatened against,
relating to or affecting either Seller or any of its respective Subsidiaries,
before any court, governmental department, commission, agency, instrumentality
or authority, or any arbitrator that seek to restrain or enjoin the consummation
of any of the Mergers or which if decided adversely to either Seller or its
respective Subsidiary could, either alone or in the aggregate with all such
claims, actions or proceedings, have a Material Adverse Effect. Except as set
forth in the Sellers SEC Reports, neither Seller nor any of its Subsidiaries is
subject to any judgment, decree, injunction, rule or order of any court,
governmental department, commission, agency, instrumentality or authority or any
arbitrator which prohibits or restricts the consummation of the transactions
contemplated hereby or which if decided adversely to either Seller or its
respective Subsidiary could, either individually or in the aggregate, have a
Material Adverse Effect.

information to be supplied by either Seller or its Subsidiaries for inclusion in
(a) the Registration Statement on Form S-4 to be filed under the Securities Act
with the SEC by Parent in connection with the Mergers for the purpose of
registering the shares of Parent Common Stock to be issued in the Mergers (the
"REGISTRATION STATEMENT") or (b) the proxy statements to be distributed in
connection with the approval of this Agreement and the transactions contemplated
hereby by the stockholders of the respective Sellers (the "PROXY STATEMENTS"
and, together with the prospectus included in the Registration Statement, the
"JOINT PROXY STATEMENTS/PROSPECTUS") will, in the case of the Proxy Statement or
any amendments thereof or supplements thereto, at the time of the mailing of the
Proxy Statement and any amendments or supplements thereto, and at the time of
any action by the stockholders of the respective Sellers in connection with the
transactions contemplated by this Agreement, or, in the case of the Registration
Statement, as amended or supplemented, at the time it becomes effective and at
the time of such action by the stockholders of the respective Sellers, contain
any untrue statement of a

                                       17
<PAGE>
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they are made, not misleading. The Joint Proxy
Statements/Prospectus will, as of its mailing date, comply as to form in all
material respects with all applicable laws, including the provisions of the
Securities Act and the Exchange Act and the rules and regulations promulgated
thereunder, except that no representation is made by either Seller with respect
to information supplied by any Purchaser for inclusion therein.

            (k) NO VIOLATION OF LAW. Except as disclosed in the Sellers SEC
Reports or in the Sellers Disclosure Schedule, neither Seller nor any of its
respective Subsidiaries is in violation of, or has been given notice or been
charged with any violation of, any law, statute, order, rule, regulation,
ordinance, or judgment (including, without limitation, any applicable
environmental law, ordinance or regulation) of any governmental or regulatory
body or authority, except for violations which, in the aggregate, could not have
a Material Adverse Effect. Except as disclosed in the Sellers SEC Reports or in
the Sellers Disclosure Schedule, as of the date of this Agreement, to the
knowledge of either Seller, no investigation or review by any governmental or
regulatory body or authority is pending or threatened, nor has any governmental
or regulatory body or authority indicated an intention to conduct the same,
other than, in each case, those the outcome of which, either individually or in
the aggregate, will not have a Material Adverse Effect. Each Seller and its
respective Subsidiaries has all permits, licenses, franchises, variances,
exemptions, orders and other governmental authorizations, consents and approvals
necessary to conduct its businesses as presently conducted (collectively, the
"SELLERS PERMITS"), except for permits, licenses, franchises, variances,
exemptions, orders, authorizations, consents and approvals the absence of which,
alone or in the aggregate, would not have a Material Adverse Effect. Each Seller
and its respective Subsidiaries is not in violation of the terms of any Sellers
Permit, except for delays in filing reports or violations which, alone or in the
aggregate, would not have a Material Adverse Effect.

            (l) COMPLIANCE WITH AGREEMENTS. Except as disclosed in the Sellers
SEC Reports, neither Seller nor any of its respective Subsidiaries is in breach
or violation of or in default in the performance or observance of any term or
provision of, and no event has occurred which, with lapse of time or action by a
third party, could result in a default under (i) the respective charter, by-laws
or other similar organizational instruments of either Seller or any of its
Subsidiaries or (ii) any contract, commitment, agreement, indenture, mortgage,
loan agreement, note, lease, bond, license, approval or other instrument to
which either Seller or any of its Subsidiaries is a party or by which any of
them is bound or to which any of their property is subject, other than, in the
case of clause (ii) of this paragraph (l), breaches, violations and defaults
which would not have, either individually or in the aggregate, a Material
Adverse Effect.

            (m)   TAXES.

                  (i) Each Seller and its respective Subsidiaries have (A) duly
      filed with the appropriate governmental authorities all Tax Returns
      required to be filed by them for all periods ending on or prior to the
      Merger 1 Effective Time, other than those Tax Returns the failure of which
      to file would not, either individually or in the aggregate, have a
      Material Adverse Effect, and such Tax Returns are true, correct and
      complete in all material respects and (B) duly paid in full or made
      adequate provision for the payment of all Taxes for all past and current
      periods, except for those Taxes, the failure to have paid would not,
      either individually or in the aggregate, have a Material Adverse Effect.
      The liabilities and reserves for Taxes reflected in each Seller's balance
      sheet included in such Seller's latest Sellers SEC Reports are adequate to
      cover all Taxes for all periods ending at or prior to the date of such
      balance sheet and there is no liability for Taxes for any period beginning
      after such date other than Taxes arising in the Ordinary Course of
      Business. There are no material liens

      Subsidiaries has received notice of an audit from any taxation authority

      deficiency, proposed deficiency or assessment from the IRS or any other
      governmental taxing authority with respect to Taxes of either Seller or
      any of its Subsidiaries which, if decided adversely, singly or in the
      aggregate, would have a Material Adverse Effect. Neither Seller nor its
      respective Subsidiaries has waived any statute of limitations in respect
      of Taxes or agreed to any extension of time with respect to a Tax
      assessment or deficiency other than waivers and extensions which are no
      longer in effect. Neither Seller nor any of its respective Subsidiaries is
      a party to any agreement providing for the allocation or sharing of Taxes
      with any entity that is not, directly or indirectly, a wholly owned
      corporate Subsidiary of such Seller other than agreements the consequences
      of which are fully and adequately reserved for in the Sellers Financial
      Statements. Neither Seller nor any of its respective corporate
      Subsidiaries has, with regard to any assets or property held, acquired or
      to be acquired by any of them, filed a consent to the application of
      Section 341(f) of the Code.

      consolidated, unitary, combined or any other basis, and such term shall
      include any interest, fines, penalties or additional amounts and any
      interest in respect of any additions, fines or penalties attributable or
      imposed or with respect to any such taxes, charges, fees, levies or other
      assessments.

                  (iii) For purposes of this Agreement, the term "TAX RETURN"
      shall mean any return, report or other document or information required to
      be supplied to a taxing authority in connection with Taxes.

      with respect to any material employee benefit plans, including employee
      benefit plans within the meaning set forth in Section 3(3) of ERISA,
      programs, arrangements, practices or other similar material arrangements
      for the provision of benefits (such plans, programs, arrangements or
      practices of Sellers and their Subsidiaries being referred to as the
      "SELLERS PLANS"), but excluding any "MULTIEMPLOYER PLAN" within the
      meaning of Section 3(37) of ERISA or a "MULTIPLE EMPLOYER PLAN" within the
      meaning of Section 413(c) of the Code. The Sellers Disclosure Schedule
      lists all Multiemployer Plans to which any of them makes contributions or
      has any obligation or liability to make contributions. Neither Seller nor
      any of its respective Subsidiaries maintains or has any liability with
      respect to any Multiple Employer Plan, which, individually or in the
      aggregate, could have a Material Adverse Effect. Neither Seller nor any of
      its respective Subsidiaries has any obligation to create or contribute to
      any additional such plan, program, arrangement or practice or to amend any
      such plan, program, arrangement or practice so as to increase benefits or
      contributions thereunder, except as required under the terms of the
      Sellers Plans or to comply with applicable law.

      Material Adverse Effect, (B) except for premiums due, there is no

      prior to the date of this Agreement, (E) the current present value of all
      projected benefit obligations under each of the Sellers Plans which is
      subject to Title IV of ERISA did not, as of its latest valuation date,
      exceed the then current value of the assets of such plan allocable to such
      benefit liabilities by more than the amount, if any, disclosed in the
      Sellers SEC Reports as of March 31, 1997, based upon reasonable actuarial
      assumptions currently utilized for such Sellers Plan, (F) each of the
      Sellers Plans has been operated and administered in all material respects
      in accordance with applicable laws during the period of time covered by
      the applicable statute of limitations, (G) each of the Sellers Plans which
      is intended to be "QUALIFIED" within the meaning of Section 401(a) of the
      Code has been determined by the IRS to be so qualified and such
      determination has not been modified, revoked or limited by failure to
      satisfy any condition thereof or by a subsequent amendment thereto or a
      failure to amend, except that it may be necessary to make additional
      amendments retroactively to maintain the "QUALIFIED" status of such
      Sellers Plans, and the period for making any such necessary retroactive
      amendments has not expired, (H) with respect to Multiemployer Plans,

      best knowledge of each Seller and its respective Subsidiaries, no event
      has occurred or is expected to occur which presents a material risk of a
      complete or partial withdrawal under said Sections 4203, 4204 and 4205,
      (I) to the best knowledge of each Seller and its respective Subsidiaries,
      there are no material pending, threatened or anticipated claims involving

      course, (J) each Seller and its respective Subsidiaries have no current
      material liability under Title IV of ERISA, and each Seller and its

      termination or resignation of any officers, directors or employees of
      either Seller or their Subsidiaries or otherwise arising out of or
      relating or due to the transactions contemplated by this Agreement. Any
      payments described in the foregoing sentence have been approved by all
      necessary corporate action by the Board of Directors of each Seller.

                  (iv) Except as set forth in the Sellers Disclosure Schedule,
      there are no agreements which will or may provide payments to any officer,
      employee, stockholder, or highly compensated individual which will be

      January 1, 1997), true and correct copies of which have been previously
      provided to the Parent (together, the "SELLERS RESERVE REPORTS"). The
      Sellers Reserve Reports are the latest reserve reports available to the
      Sellers relating to their and their Subsidiaries' reserves of oil and gas.
      The oil and gas properties evaluated in the Sellers Reserve Reports are
      referred to herein as the "SELLERS EVALUATED PROPERTIES." The Sellers have
      provided no false or misleading information to and have not withheld any

      Associates, with respect to the preparation of the Sellers Reserve Reports
 .
                  (ii) Except as set forth on Sellers Disclosure Schedule, the
      Sellers are not aware of any facts or circumstances that should reasonably
      cause the Sellers to conclude that any of the information that was
      supplied by the Sellers to Ryder Scott Company or Netherland Sewell and
      Associates, in connection with their preparation of the Sellers Reserve
      Reports is not currently correct in all material respects (other than
      normal depletion by production in the ordinary course), and to the
      Sellers' knowledge the information utilized in preparing the Sellers
      Reserve Reports is correct in all material respects.

                  (iii) The Sellers have made available to Parent certain
      information (the "SELLERS PROJECT INFORMATION") with respect to
      exploration projects in which the Sellers are currently engaged (the
      "SELLERS PROJECTS"), which information and Sellers Projects are set forth
      on the Sellers Disclosure Schedule. The Sellers Project Information
      provided by the Sellers does not contain any untrue statement of a
      material fact or omit to state a material fact necessary to make the
      statements contained therein not misleading.

            (s)   TITLE.

                  (i) The leasehold, royalty, mineral and similar interests
      owned by each Seller and their respective Subsidiaries entitle it to
      receive not less than the interest set forth in the Sellers Reserve
      Reports as the Net Revenue Interest from all oil and gas and associated
      minerals produced, saved and marketed in respect of each Sellers Evaluated
      Property listed in the Sellers Reserve Reports, and obligate it to bear
      costs and expenses relating to the maintenance and development of, and the
      operations with respect to, each such Sellers Evaluated Property in an
      amount not greater than the Working Interest set forth in the Sellers
      Reserve Reports (unless there is a corresponding increase in the Net
      Revenue Interest), except for such deficiencies which, individually or in
      the aggregate, would not have a Material Adverse Effect. Except as noted
      in the Sellers Reserve Reports, the Net Revenue Interest and the Working
      Interest with respect to each such Sellers Evaluated Property are not
      subject to change or adjustment upon the occurrence of payout or any
      similar or other event.

                  (ii) The Sellers and their Subsidiaries have, and on the
      Closing Date will have, good and valid title to all of their leasehold,
      royalty, mineral and similar interests in the Sellers Evaluated
      Properties, other than the properties disposed of since January 1, 1997 as
      disclosed on the Sellers Disclosure Schedule or since the date hereof with

      have a Material Adverse Effect, (D) contracts and agreements for the sale
      of oil and gas entered into in the Ordinary Course of Business, (E)
      lessor's royalties, overriding royalties, and division orders,
      reversionary interests and similar burdens and all existing operating
      agreements and unit agreements, if the net cumulative effect of the same
      does not operate to reduce the Net Revenue Interests of the Sellers
      Evaluated Properties to less than the Net Revenue Interests set forth in
      the Sellers Reserve Report or increase the Working Interests of the
      Sellers Evaluated Properties to more than the Working Interests set forth
      in the Sellers Reserve Report (unless there is a corresponding increase in
      the Net Revenue Interests); (F) any and all federal and state regulatory
      orders and rules to which the Sellers Evaluated Properties are presently
      subject; (G) preferential rights to purchase and required third-party
      consents to assignments and similar agreements (none of which arise or are
      required in connection with the transactions contemplated by this
      Agreement); (H) liens for Taxes not due or not delinquent at the time of
      Closing or the validity of which are being contested in good faith by
      appropriate actions; (I) all rights to consent by, required notices to,
      filings with, or other actions by governmental entities in connection with
      the sale or conveyance of oil, gas and mineral leases or interests therein
      if the same are customarily obtained after such sale or conveyance; (J)
      easements, rights-of-way, servitudes, permits, surface leases and other
      rights in respect of surface operations, pipelines, grazing, logging,
      canals, ditches, reservoirs or the like; and easements for streets,
      alleys, highways, pipelines, telephone lines, power lines, railways and
      other easements and rights-of-way, on, over or in respect of any of the
      Sellers Evaluated Properties; (K) liens of operators relating to
      obligations not yet due or not delinquent; and (L) title deficiencies
      commonly encountered in the oil and gas business which would not be
      considered material by a reasonable and prudent person engaged in the
      business of the ownership, development and operating of oil and gas
      properties with knowledge of all the facts and appreciation of their legal
      significance.

                  (iii) Except where the failure would not have a Material
      Adverse Effect, (A) neither Seller nor its respective Subsidiaries are
      dependent with respect to the Sellers Evaluated Properties on the right to
      use the properties of others, except under valid and enforceable leases,
      contracts, pooling or unitization agreements, rights or other
      arrangements, (B) the Sellers and their respective Subsidiaries own, or
      have the right to use under valid and enforceable leases, contracts,
      rights or other arrangements, all gas processing facilities necessary for
      the current operations of the Sellers and their respective Subsidiaries,
      (C) all buildings, machinery and equipment currently used in the
      operations related to the Sellers Evaluated Properties are adequate for

      Adverse Effect, the Sellers Evaluated Properties are being developed,

      leases, contracts and commitments to which either Seller or any respective
      Subsidiary is a party or by which either Seller or any respective

                  (v) The Sellers and the Subsidiaries have good and valid title
      to all the properties and assets of every kind, character and description
      (real, personal or mixed, tangible and intangible), including, without

      (B) mortgages and encumbrances which secure indebtedness or obligations
      which are properly reflected in the Sellers Financial Statements; (C)

      title and encumbrances which, individually or in the aggregate, would not
      have a Material Adverse Effect; (F) any and all federal and state
      regulatory orders and rules to which the Sellers Assets are presently

      of the Sellers, generally have the right to use all other property and
      assets as to which they do not have title but which are currently being
      used in the conduct of each Seller's business, except any rights of use
      the loss of which would not have a Material Adverse Effect.

            (t) INSURANCE. The Sellers Disclosure Schedule lists all material
insurance policies covering the Sellers Assets, the Sellers Evaluated
Properties, employees and operations of the Sellers and their respective
Subsidiaries as of the date hereof (other than insurance owned or held by

are in full force and effect, there are no defaults thereunder. Except for
claims previously made, to the knowledge of either Seller or its respective
Subsidiaries, there is no basis for any action or claim nor any facts which
would reasonably be anticipated to give rise to such action or claim. To the
knowledge of either Seller or its respective Subsidiaries, there does not exist
any event that, with the giving of notice or the lapse of time or both, would
constitute such a default. Neither Seller nor any of its respective Subsidiaries

asserted or material disputes evidenced in writing under any contract to which
either Seller or any Subsidiary thereof is a party regarding payments for
natural gas not taken pursuant to any "take or pay" or similar arrangement; (ii)

quantity of natural gas or liquids to be paid for thereafter other than in the
normal cycle of billing or received prepayments, advance payments or

                                       25
<PAGE>
loans which will require a Seller or any of its respective Subsidiaries to
perform services or deliver hydrocarbons under such contracts on or after the
Closing Date without being currently paid therefor; (iii) no sales contract
obligates either Seller or any Subsidiary thereof to deliver specific minimum
volumes of gas; (iv) no contract obligates either Seller or any Subsidiary
thereof to sell gas at prices substantially lower than the prevailing market
prices or to purchase gas at prices substantially higher than prevailing market
prices; (v) the Sellers and their respective Subsidiaries have made or will,
prior to the Closing Date, make all payments due to producers or others for all
gas and liquids delivered into any of their respective plants for which payment
for same is due prior to the Closing Date, including, without limitation, all
payments due for the purchase of gas and liquids under any contract; (vi) to the
knowledge of either Seller or any of its respective Subsidiaries, all gas
delivered into any of the plants has been purchased, and all residue gas from
the plants has been sold, in compliance with the Natural Gas Policy Act of 1978,
all orders, rules and regulations of the Federal Energy Regulatory Commission
and all other applicable laws, orders, rules and regulations; (vii) to the
knowledge of either Seller or any of its respective Subsidiaries, there exists
no material claim or dispute with respect to the purchase, or the failure to
purchase, or pay for whether or not purchased, gas under any gas purchase
contracts to which either Seller or any Subsidiary thereof is a party or the
applicable price to be paid for gas delivered, or residue gas or liquids or
products sold from the plants; and (viii) none of the Sellers Evaluated
Properties or the Sellers Assets is subject to requirements to make Btu
adjustments or affect gas or liquids balancing in favor of third parties which
would result in either Seller or any Subsidiary thereof being required to
deliver material volumes of gas or liquids after the Closing Date or otherwise
to compensate a third party for gas or liquids receipts into, or deliveries
from, the plants which occurred prior to the Closing Date. The Sellers
Disclosure Schedule sets forth an estimate of the amount of any net imbalances
and is within ten percent (10%) of the actual amount.

            (w) NO PREPAYMENTS MADE OR REFUNDS OWED. Sellers and their
respective Subsidiaries have not received any prepayment, advance payment,
deposits or similar payments, and have no refund obligation, other than
obligations in the aggregate of less than $250,000 incurred in the Ordinary
Course of Business, with respect to any gas or products purchased, sold,
gathered, processed or marketed through their plants. The Sellers and their
respective Subsidiaries have not received any compensation for gathering or
processing services relating to the plants which would be subject to any refund
or create any repayment obligation, other than obligations of less than $250,000
incurred in the Ordinary Course of Business, either by or to the Sellers and
their respective Subsidiaries, and the Sellers and their respective Subsidiaries

Subsidiaries do not have any material drilling obligations or other development
commitments that are not terminable at will by the Seller or the Subsidiary
party thereto without penalty, other than commitments and obligations that arose

the Subsidiary party thereto for a failure to participate is to suffer a
"non-consent" penalty or forfeit an interest in the undeveloped lands subject to
the commitment or obligation.

            (y) DEVELOPMENT OPERATIONS. To the knowledge of either Seller or its
respective Subsidiaries, there are in existence no facts or circumstances that
should reasonably cause a Seller or a Subsidiary to conclude that any
development operations on the Sellers Evaluated Properties that are contemplated
by the Sellers Reserve Report will not be permitted under applicable laws and
governmental rules and regulations or that any third party may have a reasonable
basis to cause any court or governmental agency with jurisdiction over such
operations to cause the suspension or termination of such operations.

representations, warranties or other statements by the Sellers in this Agreement
or in the Sellers Disclosure Schedule or Exhibits hereto or any documents
distributed generally to the Edisto Stockholders or the Convest Stockholders,
taken as a whole, do not contain any untrue statement of a material fact or omit
to state a material fact necessary to make the statements contained therein not
misleading. There is, to the knowledge of either Seller, no fact pertaining
particularly to Sellers Evaluated Properties or the Sellers Assets (as opposed
to public information concerning general industry or economic conditions or
governmental policies) which has a Material Adverse Effect on or in the future
would be reasonably expected to have a Material Adverse Effect on the Sellers
Evaluated Properties or the Sellers Assets or the ownership, operation or
maintenance of any of the Sellers Evaluated Properties or the Sellers Assets

            (bb) CERTAIN AGREEMENTS. There are no contracts, agreements,
arrangements or understandings to which either Seller or any of their
Subsidiaries is a party which create, govern or purport to govern the right of
another party (other than Purchasers) to acquire either Seller or any of their
Subsidiaries.

            (cc) SHAREHOLDERS AGREEMENT. Set forth on the Form 10-K/A of each
Seller, as filed with the SEC on April 30, 1997, is a list of the officers,
directors and owners of 5% or more of the capital stock of the respective
Sellers. Edisto has obtained from The TCW Group, Inc. and its affiliates and

effect that such person will vote shares of Edisto Common Stock and Convest
Common Stock beneficially owned by such person in favor of the Mergers, and (ii)
an Affiliate Agreement.

            (dd) BROKERS AND FINDERS. Except for the fees and expenses payable
to Petrie Parkman and Rauscher Pierce, which fees are reflected in their
agreements with Sellers (a copy of which has been delivered to the Parent),
Sellers have not entered into any contract, arrangement or understanding with
any person or firm which may result in the obligation of either Seller to pay
any finder's fees, brokerage or agent commissions or other like payments in
connection with the transactions contemplated hereby. Except for the fees and
expenses paid or payable to Petrie Parkman and to Rauscher Pierce, there is no
claim for payment by either Seller of any investment banking fees, finder's

the negotiations leading to this Agreement or the consummation of the
transactions contemplated hereby.

            (ee) OPINION OF FINANCIAL ADVISOR. The financial advisor of Edisto,

the Closing Date, Edisto will have at least $68.0 million in cash on hand (the
"EDISTO CASH BALANCE"); provided, however, that (i) the Edisto Cash Balance may
be reduced by an amount not to exceed an aggregate of $1,500,000 in order

                                       27
<PAGE>
to effect the redemption or cancellation of any Edisto Option prior to Merger 1
in accordance with the terms of Section 4(c)(i), and (ii) Edisto and Convest may
collectively expend an amount not to exceed an aggregate of $2,300,000 in order
to effect the severance payments set forth in Section 5(n)(iii) of the Sellers
Disclosure Schedule. The Edisto Cash Balance is not, and at the Closing Date
will not be, subject to any pledge, encumbrance, lien or other limitation
prohibiting its free use or distribution by Edisto or its successors.

            (gg) AFFILIATE TRANSACTIONS. To Sellers knowledge there are no
transactions between (i) the Sellers or any of their Subsidiaries and (ii) any
of their Affiliates, which are required to be disclosed in the Sellers SEC
Reports which are not disclosed.

            (hh) WARN. Sellers Disclosure Schedule sets forth the total number
of employees of the Sellers and their Subsidiaries and independent contractors
as determined in accordance with WARN or any similar applicable law. The
obligations of Sellers and their Subsidiaries under this Agreement, including,
without limitation, Section 8(d), will not give rise to any notice requirement
or payment obligation or liability under WARN on the part of Sellers or
Purchasers or their respective Subsidiaries.

            (ii) CUMULATIVE REPRESENTATIONS. To the extent the representations
and warranties of Sellers set forth herein are modified by the terms Material
Adverse Change or Material Adverse Effect or similar terms, the effect of the

respective Subsidiaries taken as a whole.

SECTION 6.  REPRESENTATIONS AND WARRANTIES OF PURCHASERS.

             Except for those matters included in the Purchasers Disclosure
Schedule, which inclusion will not be deemed an admission by Purchasers that any
such matter is material or has or would have a Material Adverse Effect or
represents a Material Adverse Change, each Purchaser represents and warrants to
the Sellers as follows:

            (a) ORGANIZATION, QUALIFICATION, AND CORPORATE POWER. Each of the
Purchasers is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation. Each of the
Purchasers is duly authorized to conduct business and is in good standing under
the laws of each jurisdiction where such qualification is required, except for
failures that would not have a Material Adverse Effect, and has not received
notice of an audit from any state taxation authority.

            (b) CAPITALIZATION. The entire authorized capital stock of Parent

preferred stock, of which 22,673,749 shares of Parent Common Stock and no shares
of preferred stock were issued and outstanding as of May 31, 1997. The shares of

transactions so contemplated. This Agreement has been duly executed and
delivered on behalf of each Purchaser and constitutes the valid and legally
binding obligation of each Purchaser, enforceable against each Purchaser in
accordance with its terms and conditions, except that (i) such enforcement may

                                       28
<PAGE>
relating to creditors' rights and (ii) the remedy of specific performance and
injunctive and other forms of equitable relief may be subject to equitable
defenses and to the discretion of the court before which any proceeding therefor

            (d) NON-CONTRAVENTION. Except as disclosed in the Purchasers
Disclosure Schedule, the execution and delivery of this Agreement by each
Purchaser do not violate, conflict with or result in a breach of any provision
of, or constitute a default (or an event which, with notice or lapse of time or
both, would constitute a default) under, or result in the termination of, or
accelerate the performance required by, or result in a right of termination or
acceleration under, or result in the creation of any lien, security interest,
charge, encumbrance or preferential right to purchase upon any of the properties
or assets of either Purchaser under any of the terms, conditions or provisions
of (i) the respective charters or by-laws of either Purchaser, (ii) any statute,

concession, contract, lease or other instrument, obligation or agreement of any
kind to which either Purchaser is now a party or by which either Purchaser or
any of their respective properties or assets may be bound or affected. Except as
disclosed in the Purchasers Disclosure Schedule, the consummation by the
Purchasers of the transactions contemplated hereby will not result in any
violation, conflict, breach, termination, acceleration or creation of liens or
preferential right to purchase under any of the terms, conditions or provisions
described in clauses (i) through (iii) of the preceding sentence. Excluded from
the foregoing sentences of this paragraph (d), insofar as they apply to the
terms, conditions or provisions described in clauses (ii) and (iii) of the first
sentence of this paragraph (d), are such violations, conflicts, breaches,
defaults, terminations, accelerations or creations of liens, security interests,
charges or encumbrances that would not, in the aggregate, have a Material
Adverse Effect.

Securities Act, and the declaration of the effectiveness thereof by the SEC and
filings with various state blue sky authorities, and (ii) the making of the
Merger Filings with the Secretaries of State of the States of Delaware and Texas
in connection with the Mergers (the filings and approvals referred to in clauses
(i) and (ii) are collectively referred to as the "PURCHASERS REQUIRED STATUTORY
APPROVALS"), no declaration, filing or registration with, or notice to, or
authorization, consent or approval of, any governmental or regulatory body or
authority is necessary for the execution and delivery of this Agreement by
either Purchaser or the consummation by either Purchaser of the transactions
contemplated hereby, including pursuant to the HSR Act, other than such
declarations, filings, registrations, notices, authorizations, consents or
approvals which, if not made or obtained, as the case may be, would not, in the
aggregate, have a Material Adverse Effect.

            (f) REPORTS AND FINANCIAL STATEMENTS. Since August 2, 1995, Parent
has filed with the SEC all forms, statements, reports and documents (including
all exhibits, post-effective amendments and supplements thereto) required to be
filed by it under each of the Securities Act, the Exchange Act and the
respective rules and regulations thereunder (collectively the "PARENT SEC
REPORTS"), all of which, as amended if applicable, complied when filed in all
material respects with all applicable requirements of the appropriate act and
the rules and regulations thereunder. As of their respective dates, the Parent
SEC Reports did not contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The audited consolidated financial statements and
unaudited interim consolidated financial statements of Parent included in such
reports (collectively, the "PARENT FINANCIAL STATEMENTS") have been prepared in
accordance with GAAP applied on a consistent basis (except as may be indicated
therein or in the notes thereto) and fairly present the financial position of
each Seller and their respective Subsidiaries as of the

                                       29
<PAGE>
dates thereof and the results of their operations and changes in financial
position for the periods then ended, subject, in the case of the unaudited
interim financial statements, to normal year-end and audit adjustments and any
other adjustments described therein.

            (g) ABSENCE OF UNDISCLOSED LIABILITIES. Except as disclosed in the
Parent SEC Reports or the Purchasers Disclosure Schedule, neither Purchaser had
at December 31, 1996, or has incurred since that date, any liabilities or
obligations (whether absolute, accrued, contingent or otherwise) of any nature,
except liabilities, obligations or contingencies which (i) are accrued or
reserved against in the Purchasers Financial Statements or reflected in the
notes thereto, (ii) would not, in the aggregate, have a Material Adverse Effect,
(iii) have been discharged or paid in full prior to the date hereof, or (iv) are
of a nature not required to be reflected in the consolidated financial
statements of Parent prepared in accordance with GAAP consistently applied and
which were incurred in the Ordinary Course of Business.

            (h) ABSENCE OF CERTAIN CHANGES OR EVENTS. Since the date of the most
recent Parent SEC Report that contains consolidated financial statements, there
has not been any Material Adverse Change.

            (i) LITIGATION. Except as disclosed in the Parent SEC Reports or in
the Purchasers Disclosure Schedule, there are no claims, suits, actions or
proceedings pending or, to the knowledge of either Purchaser, threatened
against, relating to or affecting either Purchaser, before any court,
governmental department, commission, agency, instrumentality or authority, or
any arbitrator that seek to restrain or enjoin the consummation of any of the
Mergers or which if decided adversely to such Purchaser could, either alone or
in the aggregate with all such claims, actions or proceedings, have a Material
Adverse Effect. Except as set forth in the Parent SEC Reports, neither Purchaser
is subject to any judgment, decree, injunction, rule or order of any court,
governmental department, commission, agency, instrumentality or authority or any
arbitrator which prohibits or restricts the consummation of the transactions
contemplated hereby or which if decided adversely to such Purchaser could,
either individually or in the aggregate, have a Material Adverse Effect.

            (j) REGISTRATION STATEMENT AND PROXY STATEMENTS. None of the
information to be supplied by either Purchaser for inclusion in (a) the
Registration Statement or (b) the Proxy Statements will, in the case of the
Proxy Statements or any amendments thereof or supplements thereto, at the time
of the mailing of the Proxy Statements and any amendments or supplements
thereto, and at the time of any action by the stockholders of the respective
Sellers in connection with the transactions contemplated by this Agreement, or,
in the case of the Registration Statement, as amended or supplemented, at the
time it becomes effective and at the time of such action by the stockholders of
the respective Sellers, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in the light of the circumstances under which
they are made, not misleading. The Joint Proxy Statements/Prospectus will, as of
its mailing date, comply as to form in all material respects with all applicable
laws, including the provisions of the Securities Act and the Exchange Act and
the rules and regulations promulgated thereunder, except that no representation
is made by either Purchaser with respect to information supplied by any Seller
or the stockholders of any Seller for inclusion therein.

            (k) NO VIOLATION OF LAW. Except as disclosed in the Parent SEC
Reports or in the Purchasers Disclosure Schedule, neither Purchaser is in
violation of, or has been given notice or been charged with any violation of,
any law, statute, order, rule, regulation, ordinance, or judgment (including,
without limitation, any applicable environmental law, ordinance or regulation)
of any governmental or regulatory body or authority, except for violations
which, in the aggregate, could not have a Material Adverse Effect. Except as
disclosed in the Parent SEC Reports or in the Purchasers Disclosure Schedule, as
of the date of this

                                       30
<PAGE>
Agreement, to the knowledge of either Purchaser, no investigation or review by
any governmental or regulatory body or authority is pending or threatened, nor
has any governmental or regulatory body or authority indicated an intention to
conduct the same, other than, in each case, those the outcome of which, either
individually or in the aggregate, will not have a Material Adverse Effect. Each
Purchaser has all permits, licenses, franchises, variances, exemptions, orders
and other governmental authorizations, consents and approvals necessary to
conduct its businesses as presently conducted (collectively, the "PURCHASERS
PERMITS"), except for permits, licenses, franchises, variances, exemptions,
orders, authorizations, consents and approvals the absence of which, alone or in
the aggregate, would not have a Material Adverse Effect. Each Purchaser is not
in violation of the terms of any Purchasers Permit, except for delays in filing
reports or violations which, alone or in the aggregate, would not have a
Material Adverse Effect.

            (l) COMPLIANCE WITH AGREEMENTS. Except as disclosed in the Parent
SEC Reports, neither Purchaser is in breach or violation of or in default in the
performance or observance of any term or provision of, and no event has occurred
which, with lapse of time or action by a third party, could result in a default
under (i) the respective charter, by-laws or other similar organizational
instruments of either Purchaser or (ii) any contract, commitment, agreement,
indenture, mortgage, loan agreement, note, lease, bond, license, approval or
other instrument to which either Purchaser is a party or by which any of them is
bound or to which any of their property is subject, other than, in the case of
clause (ii) of this paragraph (l), breaches, violations and defaults which would
not have, either individually or in the aggregate, a Material Adverse Effect.

            (m) TAXES. Each Purchaser has (A) duly filed with the appropriate
governmental authorities all Tax Returns required to be filed by them for all
periods ending on or prior to the Merger 1 Effective Time, other than those Tax
Returns the failure of which to file would not, either individually or in the
aggregate, have a Material Adverse Effect, and such Tax Returns are true,
correct and complete in all material respects and (B) duly paid in full or made
adequate provision for the payment of all Taxes for all past and current
periods, except for those Taxes, the failure to have paid would not, either
individually or in the aggregate, have a Material Adverse Effect. The
liabilities and reserves for Taxes reflected in Parent's balance sheet included
in the latest Parent SEC Reports are adequate to cover all Taxes for all periods
ending at or prior to the date of such balance sheet and there is no liability
for Taxes for any period beginning after such date other than Taxes arising in
the Ordinary Course of Business. There are no material liens for Taxes upon any
property or assets of either Purchaser, except for liens for Taxes not yet due.
Except as set forth on the Purchasers Disclosure Schedule, neither Purchaser nor
its respective Subsidiaries has received notice of an audit from any taxation
authority which could reasonably be expected to have a Material Adverse Change.
There are no unresolved issues of law or fact arising out of a notice of
deficiency, proposed deficiency or assessment from the IRS or any other
governmental taxing authority with respect to Taxes of either Purchaser which,
if decided adversely, singly or in the aggregate, would have a Material Adverse
Effect. Neither Purchaser has waived any statute of limitations in respect of
Taxes or agreed to any extension of time with respect to a Tax assessment or
deficiency other than waivers and extensions which are no longer in effect.
Neither Purchaser is a party to any agreement providing for the allocation or
sharing of Taxes with any entity that is not, directly or indirectly, a wholly
owned corporate Subsidiary of such Purchaser other than agreements the
consequences of which are fully and adequately reserved for in the Parent
Financial Statements. Neither Purchaser has, with regard to any assets or
property held, acquired or to be acquired by any of them, filed a consent to the
application of Section 341(f) of the Code.

            (n)   EMPLOYEE BENEFIT PLANS; ERISA.

                  (i) Except as disclosed in the Parent SEC Reports or
      Purchasers Disclosure Schedule, at the date hereof, Purchasers do not
      maintain or contribute to or have any obligation or

                                       31
<PAGE>
      liability to or with respect to any material employee benefit plans,
      including employee benefit plans within the meaning set forth in Section

      meaning of Section 3(37) of ERISA or a "MULTIPLE EMPLOYER PLAN" within the
      meaning of Section 413(c) of the Code. The Purchasers Disclosure Schedule
      lists all Multiemployer Plans to which any of them makes contributions or
      has any obligation or liability to make contributions. Neither Purchaser
      maintains or has any liability with respect to any Multiple Employer Plan,
      which, individually or in the aggregate, could have a Material Adverse
      Effect. Neither Purchaser has any obligation to create or contribute to
      any additional such plan, program, arrangement or practice or to amend any
      such plan, program, arrangement or practice so as to increase benefits or
      contributions thereunder, except as required under the terms of the
      Purchasers Plans, under existing collective bargaining agreements or to

      aggregate, could have a Material Adverse Effect, (B) except for premiums
      due, there is no outstanding material liability, whether measured alone or
      in the aggregate, under Title IV of ERISA with respect to any of the
      Purchasers Plans, (C) neither the Pension Benefit Guaranty Corporation nor
      any plan administrator has instituted proceedings to terminate any of the
      Purchasers Plans subject to Title IV of ERISA other than in a "STANDARD
      TERMINATION" described in Section 4041(b) of ERISA, (D) none of the
      Purchasers Plans has incurred any "ACCUMULATED FUNDING DEFICIENCY" (as
      defined in Section 302 of ERISA and Section 412 of the Code), whether or
      not waived, as of the last day of the most recent fiscal year of each of
      the Purchasers Plans ended prior to the date of this Agreement, (E) the
      current present value of all projected benefit obligations under each of
      the Purchasers Plans which is subject to Title IV of ERISA did not, as of
      its latest valuation date, exceed the then current value of the assets of
      such plan allocable to such benefit liabilities by more than the amount,
      if any, disclosed in the Parent SEC Reports as of March 31, 1997, based
      upon reasonable actuarial assumptions currently utilized for such
      Purchasers Plan, (F) each of the Purchasers Plans has been operated and
      administered in all material respects in accordance with applicable laws
      during the period of time covered by the applicable statute of
      limitations, (G) each of the Purchasers Plans which is intended to be
      "QUALIFIED" within the meaning of Section 401(a) of the Code has been
      determined by the IRS to be so qualified and such determination has not
      been modified, revoked or limited by failure to satisfy any condition
      thereof or by a subsequent amendment thereto or a failure to amend, except
      that it may be necessary to make additional amendments retroactively to
      maintain the "QUALIFIED" status of such Purchasers Plans, and the period
      for making any such necessary retroactive amendments has not expired, (H)
      with respect to Multi-employer Plans, neither Purchaser has made or
      suffered a "COMPLETE WITHDRAWAL" or a "PARTIAL WITHDRAWAL," as such terms
      are respectively defined in Sections 4203, 4204 and 4205 of ERISA and, to
      the best knowledge of each Purchaser, no event has occurred or is expected
      to occur which presents a material risk of a complete or partial
      withdrawal under said Sections 4203, 4204 and 4205, (I) to the best

      ERISA or Chapter 43 of Subtitle (A) of the Code. None of the Purchasers
      Plans has an "ACCUMULATED FUNDING DEFICIENCY" (as defined in Section 302
      of ERISA and Section 412 of the Code) or is required to provide security
      to a Purchasers Plan pursuant to Section 401(a)(29) of the Code. Each
      Purchasers Plan can be unilaterally terminated by a Purchaser at any time
      without material liability, other than for amounts previously reflected in
      the financial statements (or notes thereto) included in the Parent SEC
      Reports.

                  (iii) The Parent SEC Reports or the Purchasers Disclosure
      Schedule contain a true and complete summary or list of or otherwise

            (q)   RESERVE REPORT AND EXPLORATION PROJECT INFORMATION.

                  (i) The Purchasers have made available to the Sellers certain
      reports dated March 3, 1997, prepared by the independent petroleum
      engineering firm of Netherland, Sewell & Associates, Inc., with respect to
      onshore properties, and dated February 7, 1997, prepared by the
      independent petroleum engineering firm of Collarini Engineering Inc., with
      respect to offshore properties (collectively, the "PURCHASERS PETROLEUM
      ENGINEERS") true and correct copies of which have been previously provided
      to the Sellers (together, the "PURCHASERS RESERVE REPORTS"). The
      Purchasers Reserve Reports are the latest reserve reports available to the
      Purchasers relating to their and their Subsidiaries reserves of oil and
      gas. The oil and gas properties evaluated in the Purchasers Reserve
      Reports are referred to herein as the "PURCHASERS EVALUATED PROPERTIES."
      The Purchasers have provided no materially false or misleading information
      to and have not withheld any material information from the Purchasers
      Petroleum Engineers, with respect to the preparation of the Purchasers
      Reserve Reports.

                  (ii) Except as set forth on the Purchasers Disclosure
      Schedule, the Purchasers are not aware of any facts or circumstances that
      should reasonably cause the Purchasers to conclude that any of the
      information that was supplied by the Purchasers to the Purchasers
      Petroleum Engineers, in connection with their preparation of the
      Purchasers Reserve Reports is not currently correct in all material
      respects (other than normal depletion by production in the ordinary
      course), and to the Purchasers' knowledge the information utilized in
      preparing the Reserve Reports is correct in all material respects.

                  (iii) The Purchasers have made available to Sellers certain
      information (the "PURCHASERS PROJECT INFORMATION") with respect to certain
      exploration projects in which the Purchasers are currently engaged (the
      "PURCHASERS PROJECTS"), which information and Purchasers Projects are set
      forth on the Purchasers Disclosure Schedule. The Purchasers Project
      Information provided by the Purchasers does not contain any untrue
      statement of a material fact or omit to state a material fact necessary to
      make the statements contained therein not misleading.

            (r)   TITLE.

                  (i) The leasehold, royalty, mineral and similar interests
      owned by the Purchasers and their respective Subsidiaries entitle them to
      receive not less than the interest set forth in the Purchasers Reserve
      Reports as the Net Revenue Interest from all oil and gas and associated
      minerals produced, saved and marketed in respect of each Purchasers
      Evaluated Property listed in the Purchasers Reserve Reports, and obligate
      it to bear costs and expenses relating to the maintenance and development
      of, and the operations with respect to, each such Purchasers Evaluated
      Property in an amount not greater than the Working Interest set forth in
      the Purchasers Reserve Reports (unless there is a corresponding increase
      in the Net Revenue Interest), except for such deficiencies which,
      individually or in the aggregate, would not have a Material Adverse
      Effect. Except as noted in the Purchasers Reserve Reports, the Net Revenue
      Interest and the Working Interest with respect to each such Purchasers
      Evaluated Property are not subject to change or adjustment upon the
      occurrence of payout or any similar or other event.

                  (ii) The Purchasers have, and on the Closing Date will have,
      good and valid title to all of their leasehold, royalty, mineral and
      similar interests in the Purchasers Evaluated Properties, other than the
      properties disposed of since the date hereof, free and clear of all
      encumbrances and title

      the sale of oil and gas entered into in the Ordinary Course of Business,
      (E) lessor's royalties, overriding royalties, and division orders,
      reversionary interests and similar burdens and all existing operating
      agreements and unit agreements, if the net cumulative effect of the same
      does not operate to reduce the Net Revenue Interests of the Purchasers
      Evaluated Properties to less than the Net Revenue Interests set forth in
      Purchasers Reserve Report or increase the Working Interests of the
      Purchasers Evaluated Properties to more than the Working Interests set
      forth in the Purchasers Reserve Report (unless there is a corresponding
      increase in the Net Revenue Interests); (F) any and all federal and state
      regulatory orders and rules to which the Purchasers Evaluated Properties
      are presently subject; (G) preferential rights to purchase and required

      rights to consent by, required notices to, filings with, or other actions
      by governmental entities in connection with the sale or conveyance of oil,
      gas and mineral leases or interests therein if the same are customarily
      obtained after such sale or conveyance; (J) easements, rights-of-way,
      servitudes, permits, surface leases and other rights in respect of surface
      operations, pipelines, grazing, logging, canals, ditches, reservoirs or

      telephone lines, power lines, railways and other easements and
      rights-of-way, on, over or in respect of any of the Purchasers Evaluated
      Properties; (K) liens of operators relating to obligations not yet due or
      not delinquent; and (L) title deficiencies commonly encountered in the oil
      and gas business which would not be considered material by a reasonable
      and prudent person engaged in the business of the ownership, development
      and operating of oil and gas properties with knowledge of all the facts
      and appreciation of their legal significance.

                  (iii) Except where the failure would not have a Material
      Adverse Effect, (A) neither Purchaser is dependent with respect to the
      Purchasers Evaluated Properties on the right to use the properties of
      others, except under valid and enforceable leases, contracts, pooling or
      unitization agreements, rights or other arrangements, (B) the Purchasers
      own, or have the right to use under valid and enforceable leases,
      contracts, rights or other arrangements, all gas processing facilities
      necessary for the current operations of the Purchasers, (C) all buildings,
      machinery and equipment currently used in the operations related to the
      Purchasers Evaluated Properties are adequate for their normal operation
      consistent with industry practice, are in good working order and
      substantially conform with all applicable Environmental Laws and (D) to
      the knowledge of either Purchaser there is no pending or threatened
      condemnation or expropriation of any part of the Purchasers Evaluated
      Properties.

                  (iv) Except where the failure would not have a Material
      Adverse Effect, the Purchasers Evaluated Properties are being developed,
      operated and maintained in compliance in all material respects with all
      leases, contracts and commitments to which either Purchaser is a party or
      by which either Purchaser or any of the Purchasers Evaluated Properties is
      bound.

                  (v) The Purchasers have good and valid title to all the
      properties and assets of every kind, character and description (real,
      personal or mixed, tangible and intangible), including, without
      limitation, all parcels of real property, pipelines, rights-of-way and
      easements and other incidental rights and permits, but excluding the
      Purchasers Evaluated Properties, reflected in the Parent Financial
      Statements or which would have been reflected in the Parent Financial
      Statements

                                       35

      if acquired prior to March 31, 1997, (the "PURCHASERS ASSETS") free and

      interests therein if the same are customarily obtained after such sale or

      leases and other rights in respect of surface operations, pipelines,

      any of the Purchasers Assets; (K) liens of operators relating to

      Adverse Effect.

            (s) INSURANCE. The Purchasers Disclosure Schedule lists all material
insurance policies covering the Purchasers Assets, the Purchasers Evaluated
Properties, employees and operations of the Purchasers as of the date hereof
(other than insurance owned or held by operators for those Purchasers Assets or
Purchasers Evaluated Properties where a party other than a Purchaser is the
operator). Such policies are in full force and effect, there are no defaults
thereunder. Except for claims previously made, to the knowledge of either
Purchaser there is no basis for any action or claim nor any facts which would
reasonably be anticipated to give rise to such action or claim. To the knowledge
of either Purchaser, there does not exist any event that, with the giving of
notice or the lapse of time or both, would constitute such a default. Neither
Purchaser is a co-insurer under any such policies of insurance except to the
extent of the amount of the deductible, self-retention or similar amounts
applicable to such policies.

            (t) ALLOWABLE PRODUCTION QUOTAS. To the knowledge of either
Purchaser, no production from any of the Purchasers Evaluated Properties prior
to the date hereof was in excess of allowable production quotas allowed or

date hereof to restrictions or penalties except as will not have a Material
Adverse Effect.

            (u) GAS PAYMENTS; BALANCING. (i) There are no material claims
asserted or material disputes evidenced in writing under any contract to which

thereafter other than in the normal cycle of billing or received prepayments,
advance payments or loans which will require a Purchaser to perform services or
deliver hydrocarbons under such contracts on or after the Closing Date without
being currently paid therefor; (iii) no sales contract obligates either
Purchaser to deliver specific minimum volumes of gas; (iv) no

                                       36
<PAGE>
contract obligates either Purchaser to sell gas at prices substantially lower
than the prevailing market prices or to purchase gas at prices substantially
higher than prevailing market prices; (v) the Purchasers have made or will,
prior to the Closing Date, make all payments due to producers or others for all
gas and liquids delivered into any of their respective plants for which payment
for same is due prior to the Closing Date, including, without limitation, all
payments due for the purchase of gas and liquids under any contract; (vi) to the
knowledge of either Purchaser, all gas delivered into any of the plants has been
purchased, and all residue gas from the plants has been sold, in compliance with
the Natural Gas Policy Act of 1978, all orders, rules and regulations of the
Federal Energy Regulatory Commission and all other applicable laws, orders,
rules and regulations; (vii) to the knowledge of either Purchaser, there exists
no material claim or dispute with respect to the purchase, or the failure to
purchase, or pay for whether or not purchased, gas under any gas purchase
contracts to which either Purchaser is a party or the applicable price to be
paid for gas delivered, or residue gas or liquids or products sold from the
plants; and (viii) none of the Purchasers Evaluated Properties or the Purchaser
Assets is subject to requirements to make Btu adjustments or affect gas or
liquids balancing in favor of third parties which would result in either
Purchaser being required to deliver material volumes of gas or liquids after the
Closing Date or otherwise to compensate a third party for gas or liquids
receipts into, or deliveries from, the plants which occurred prior to the
Closing Date. The Purchasers Disclosure Schedule sets forth an estimate of the
amount of any material net imbalances and is within ten percent (10%) of the
actual amount.

            (v) NO PREPAYMENTS MADE OR REFUNDS OWED. Purchasers have not
received any prepayment, advance payment, deposits or similar payments, and have
no refund obligation, other than obligations in the aggregate of less than
$500,000 incurred in the Ordinary Course of Business, with respect to any gas or
products purchased, sold, gathered, processed or marketed through their plants.
The Purchasers have not received any compensation for gathering or processing
services relating to the plants which would be subject to any refund or create
any repayment obligation, other than obligations of less than $500,000 incurred
in the Ordinary Course of Business, either by or to the Purchasers, and the
Purchasers are not aware of any basis for a claim that a refund is due.

            (w) DRILLING OBLIGATIONS. The Purchasers do not have any material
drilling obligations or other development commitments that are not terminable at
will by the Purchaser party thereto without penalty, other than commitments and
obligations that arose in the Ordinary Course of Business where the sole
consequence to the Purchaser party thereto for a failure to participate is to
suffer a "non-consent" penalty or forfeit an interest in the undeveloped lands
subject to the commitment or obligation.

            (x) DEVELOPMENT OPERATIONS. To the knowledge of either Purchaser,
there are in existence no facts or circumstances that should reasonably cause a
Purchaser to conclude that any development operations on the Purchasers
Evaluated Properties that are contemplated by the Purchasers Reserve Report will
not be permitted under applicable laws and governmental rules and regulations or
that any third party may have a reasonable basis to cause any court or
governmental agency with jurisdiction over such operations to cause the
suspension or termination of such operations.

            (y) REGULATORY AUTHORITY. As of the date hereof, neither Purchaser
is subject to regulation as (a) a "holding company," an "affiliate" of a
"holding company" or a "subsidiary company" of a "holding company" or a "public
utility," as each of such terms is defined in the Public Utility Holding Company
Act of 1935, as amended, and the rules and regulations thereunder; (b) a gas
utility or utility under applicable state law; and (c) an "investment company,"
or a company "controlled" by an "investment company," within the meaning of the
Investment Company Act of 1940, as amended.

and warranties of Purchasers set forth herein are modified by the terms Material

            (a) CONDUCT OF BUSINESS BY THE SELLERS PENDING THE MERGERS. Except

      options, warrants or rights of any kind to acquire any shares of their
      capital stock of any class or any debt or equity securities convertible

      options and warrants outstanding on the date hereof;

                  (iv) not (A) incur or become contingently liable with respect

                                       38

      action or failure to take action would cause either Seller or its
      stockholders (except to the extent that any stockholders receive cash) to
      recognize gain or loss for federal income tax purposes as a result of the
      consummation of Merger 3 or would otherwise cause Merger 3 not to qualify

Agreement shall give to Parent, directly or indirectly, rights to control or

            (c)   ACQUISITION TRANSACTIONS.

                  (i) After the date hereof and prior to the Merger 3 Effective
      Time or earlier termination of this Agreement, the Sellers shall not, and
      shall not permit any of their Subsidiaries to, initiate, solicit,
      negotiate, encourage or provide confidential information to facilitate,
      and the Sellers shall, and shall cause each of their Subsidiaries to,
      cause any officer, director or employee of, or any attorney, accountant,
      investment banker, financial advisor or other agent retained by them, not
      to initiate, solicit, negotiate, encourage or provide non-public or
      confidential information to facilitate, any proposal or offer to acquire
      all or any substantial part of the business and properties of either
      Seller or any of their Subsidiaries or any capital stock of either Seller
      or any of their Subsidiaries, whether by merger, purchase of assets,
      tender offer or otherwise, whether for cash, securities or any other
      consideration or combination thereof (any such transactions being referred
      to herein as an "ACQUISITION TRANSACTION").

                  (ii) Notwithstanding the provisions of subsection (i) above,
      (A) either Seller may, in response to an unsolicited written proposal or
      unsolicited written indication of interest with respect to a potential or
      proposed Acquisition Transaction ("ACQUISITION PROPOSAL"), furnish
      (subject to the execution of a confidentiality agreement and standstill
      agreement in substantially the form executed by Parent) confidential or
      non-public information to a financially capable corporation, partnership,
      person or other entity or group (a "POTENTIAL ACQUIRER") and negotiate
      with such Potential Acquirer if the Board of Directors of such Seller
      after consulting with its outside legal counsel, determines in good faith
      that the failure to provide such confidential or non-public information to
      or negotiate with such Potential Acquirer would constitute a breach of its
      fiduciary duty to its stockholders and (B) such Seller's Board of
      Directors may take and disclose to its stockholders a position
      contemplated by Rule 14e-2 under the Exchange Act. It is understood and
      agreed that negotiations conducted in accordance with this subsection (ii)
      shall not constitute a violation of subsection (i) of this Section 7(c).

                  (iii) The Sellers shall immediately notify Parent after
      receipt of any Acquisition Proposal or any request for nonpublic
      information relating to a Seller or its Subsidiaries in connection with an
      Acquisition Proposal or for access to the properties, books or records of
      a Seller or any Subsidiary by any person or entity that informs the Board
      of Directors of a Seller or such Subsidiary that it is considering making,
      or has made, an Acquisition Proposal. Such notice to Parent shall be made
      orally and in writing and shall indicate in reasonable detail the identity
      of the offeror and the terms and conditions of such proposal, inquiry or
      contact. Seller shall immediately provide Parent a copy of all information
      provided to a third party.

                  (iv) Each Party (i) acknowledges that a breach of any of its
      covenants contained in this Section 7(c) will result in irreparable harm
      to the other Party which will not be compensable in money damages, and
      (ii) agrees that such covenant shall be specifically enforceable and that
      specific performance and injunctive relief shall be a remedy properly
      available to the other Party for a breach of such covenant. In any event,
      if a Seller enters into an Acquisition Transaction, it will immediately
      pay to Parent the sums described in Section 10(b) below.

            (d) SUBSIDIARIES. Each Seller will, following direction from Parent,
dissolve all inactive Subsidiaries (other than MINT Holding Company) prior to
Merger 1. Prior to Merger 1, Sellers will cause the merger of Edisto Exploration
and Production Company ("Edisto E&P") into Convest.

Section 8.  ADDITIONAL AGREEMENTS.

<PAGE>
            (a)   ACCESS TO INFORMATION.

                  (i) The Sellers and their Subsidiaries shall afford to
      Purchasers and their respective accountants, counsel, financial advisors
      and other representatives (the "PARENT REPRESENTATIVES") and Parent and
      its Subsidiaries shall afford to the Sellers and their accountants,
      counsel, financial advisors and other representatives (the "SELLER
      REPRESENTATIVES") full access during normal business hours throughout the
      period prior to the Merger 1 Effective Time to all of their respective
      properties, books, contracts, commitments and records (including, but not
      limited to, Tax Returns) and, during such period, shall furnish promptly
      to one another (A) a copy of each report, schedule and other document
      filed or received by any of them pursuant to the requirements of federal
      or state securities laws or filed by any of them with the SEC in
      connection with the transactions contemplated by this Agreement and (B)
      such other information concerning their respective businesses, properties
      and personnel as a Purchaser or Seller, as the case may be, shall
      reasonably request; PROVIDED, HOWEVER, that no investigation pursuant to
      this Section 8(a) shall amend or modify any representations or warranties
      made herein or the conditions to the obligations of the respective parties
      to consummate the Mergers. Parent and its Subsidiaries shall hold and
      shall use their reasonable best efforts to cause the Parent
      Representatives to hold, and the Sellers and their Subsidiaries shall hold
      and shall use their reasonable best efforts to cause the Seller
      Representatives to hold, in strict confidence all non-public documents and
      information furnished to a Purchaser or Seller, as the case may be, in
      connection with the transactions contemplated by this Agreement, except
      that (x) a Purchaser or Seller may disclose such information as may be
      necessary in connection with seeking the Purchasers Required Statutory
      Approvals, the Sellers Required Statutory Approvals and the Requisite
      Stockholder Approvals and (y) a Purchaser or Seller may disclose any
      information that it is required by law or judicial or administrative order
      to disclose.

                  (ii) In the event that this Agreement is terminated in
      accordance with its terms, each Party shall promptly redeliver to the
      other all non-public written material provided pursuant to this Section
      8(a) and shall not retain any copies, extracts or other reproductions in
      whole or in part of such written material. In such event, all documents,
      memoranda, notes and other writings prepared by a Purchaser or Seller
      based on the information in such material shall be destroyed (and Parent
      and the Sellers shall use their respective reasonable best efforts to
      cause their advisors and representatives to similarly destroy their
      documents, memoranda and notes), and such destruction (and reasonable best
      efforts) shall be certified in writing by an authorized officer
      supervising such destruction.

                  (iii) The Sellers shall promptly advise Parent and Parent
      shall promptly advise the Sellers in writing of any change or the
      occurrence of any event after the date of this Agreement having, or which,
      insofar as can reasonably be foreseen, in the future may have, either
      individually or in the aggregate, any Material Adverse Effect.

            (b) REGISTRATION STATEMENT AND PROXY STATEMENTS. Parent and the
Sellers shall file with the SEC as soon as is reasonably practicable after the
date hereof the Joint Proxy Statements/Prospectus and shall use all reasonable
efforts to have the Registration Statement declared effective by the SEC as
promptly as practicable. Parent shall also take any action reasonably required
to be taken under applicable state blue sky or securities laws in connection
with the issuance of Parent Common Stock pursuant hereto. Parent and the Sellers
shall promptly furnish to each other all information, and take such other
actions, as may reasonably be requested in connection with any action by any of
them in connection with the preceding sentence. The information provided and to
be provided by Parent and the Sellers, respectively, for use in the Joint Proxy
Statements/Prospectus shall not contain any untrue statement of a material fact
or omit to state a material fact

                                       41
<PAGE>
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading.

            (c) STOCKHOLDERS' APPROVALS. Each Seller shall, as promptly as
practicable, submit this Agreement and the transactions contemplated hereby for
the approval of its stockholders at a meeting of stockholders or by written
consent and shall use its best efforts to obtain the Requisite Stockholder
Approvals and adoption of this Agreement and the transactions contemplated
hereby. Such meeting of stockholders shall be held or written consent effected
as soon as practicable following the date upon which the Registration Statement
becomes effective. The Sellers shall, through their respective Boards of
Directors, recommend to their stockholders approval of the transactions
contemplated by this Agreement. Each Seller (i) acknowledges that a breach of
its covenant contained in this Section 8(c) to convene a meeting of its
stockholders and call for a vote thereat with respect to the approval of this
Agreement and the Mergers will result in irreparable harm to Parent which will
not be compensable in money damages and (ii) agrees that such covenant shall be
specifically enforceable and that specific performance and injunctive relief
shall be a remedy properly available to Parent for a breach of such covenant.

            (d)   EMPLOYEE MATTERS.

            (i) Not less than five business days prior to the Closing Date each
      Seller and their Subsidiaries shall provide Parent a current list of their
      respective officers, directors and employees. Except as otherwise
      designated by Parent, at least five business days prior to the Closing,
      each Seller and their Subsidiaries shall obtain the resignation or shall
      terminate each of their respective officers, directors and employees
      effective not later than the Merger 3 Effective Time. At or immediately
      prior to Closing, the Sellers shall pay any severance pay, stay bonuses or
      similar payments required to be paid pursuant to the terms of the
      agreements described on Section 5(n)(iii) of the Sellers Disclosure
      Schedule. Without limiting the foregoing, this provision will cause a
      termination of Michael Y. McGovern under the employment agreement between
      him and Edisto, a copy of which has been previously provided to the
      Purchasers.

            (ii) Parent agrees that, following the Merger 3 Effective Time, it
      will provide continuation coverage, as required by the Consolidated
      Omnibus Budget Reconciliation Act of 1985 ("COBRA"), to be given to any
      employee of Sellers or their respective Subsidiaries whose employment has
      been or will be terminated. The parties understand that COBRA may require
      that such continuation coverage be provided for a period of up to
      thirty-six months as provided in Section 4980B of the Internal Revenue
      Code of 1986, as amended, at the qualified beneficiary's expense.

            (iii) Prior to the Merger 1 Effective Time, Edisto and Convest shall
      have taken all steps, subject to Parent's approval, necessary or
      appropriate so that the Convest Savings and Investment Plan and Trust, the
      Edisto Savings and Investment Plan and Trust and any other Sellers Plan
      that is or is intended to be a "qualified" plan under Section 401(a) of
      the Code shall have been terminated.

            (e) QUOTATION. Parent shall use its reasonable best efforts to
effect, at or before the Merger 1 Effective Time, authorization for listing on
the NYSE or such other exchange on which Parent Common Stock is then primarily
traded, upon official notice of issuance, of the shares of Parent Common Stock
to be issued pursuant to the Mergers.

<PAGE>
            (f)   AGREEMENT TO COOPERATE.

                  (i) Subject to the terms and conditions herein provided and
      subject to the fiduciary duties of the respective boards of directors of
      the Parent and the Sellers, each of the Parties hereto shall use all
      reasonable efforts to take, or cause to be taken, all action and to do, or
      cause to be done, all things necessary, proper or advisable under
      applicable laws and regulations to consummate and make effective the
      transactions contemplated by this Agreement, including using its
      reasonable efforts to obtain all necessary or appropriate waivers,
      consents or approvals of third parties required in order to preserve
      material contractual relationships of the Sellers and their respective
      Subsidiaries, all necessary or appropriate waivers, consents and approvals
      and SEC "no-action" letters to effect all necessary registrations, filings
      and submissions and to lift any injunction or other legal bar to the
      Mergers (and, in such case, to proceed with the Mergers as expeditiously
      as possible).

                  (ii) In the event any litigation is commenced by any person or
      entity relating to the transactions contemplated by this Agreement,
      including any Acquisition Transaction, Parent shall have the right, at its
      own expense, to participate therein, and the Sellers will not settle any
      such litigation without the consent of Parent, which consent will not be
      unreasonably withheld.

            (g) PUBLIC STATEMENTS. The Parties shall consult with each other
prior to issuing any press release or any written public statement with respect
to this Agreement or the transactions contemplated hereby and shall not issue
any such press release or written public statement prior to such consultation.

            (h) NOTIFICATION OF CERTAIN MATTERS. Each of the Purchasers and the
Sellers agrees to give prompt notice to each other of, and to use their
respective reasonable best efforts to prevent or promptly remedy, (A) the
occurrence or failure to occur or the impending or threatened occurrence or
failure to occur, of any event which occurrence or failure to occur would be
likely to cause any of its representations or warranties in this Agreement to be
untrue or inaccurate in any material respect at any time from the date hereof to
the Merger 1 Effective Time and (B) any material failure on its part to comply
with or satisfy any covenant, condition or agreement to be complied with or
satisfied by it hereunder; PROVIDED, HOWEVER, that the delivery of any notice
pursuant to this Paragraph 8(h) shall not limit or otherwise affect the remedies
available hereunder to the party receiving such notice.

            (i) CORRECTIONS TO THE JOINT PROXY STATEMENTS/PROSPECTUS AND
REGISTRATION STATEMENT. Prior to the date of approval of the Mergers by the
Sellers' respective stockholders, each of the Purchasers and Sellers shall
correct promptly any information provided by it to be used specifically in the
Joint Proxy Statements/Prospectus and Registration Statement that shall have
become false or misleading in any material respect and shall take all steps
necessary to file with the SEC and have declared effective or cleared by the SEC
any amendment or supplement to the Joint Proxy Statements/Prospectus or the
Registration Statement so as to correct the same and to cause the Joint Proxy
Statements/Prospectus as so corrected to be disseminated to the stockholders of
the Sellers, in each case to the extent required by applicable law.

            (j)   INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.

                  (i) From and after the Merger 1 Effective Time, with respect
      to Edisto, and the Merger 3 Effective Time, with respect to Convest,
      Parent agrees that it will indemnify and hold harmless each present and
      former director and/or officer of a Seller, determined as of such
      effective time (the "Indemnified Parties"), that is made a party or
      threatened to be made a party to any threatened, pending or completed,
      action, suit, proceeding or claim, whether civil, criminal,

                                       43
<PAGE>
      administrative or investigative, by reason of the fact that he or she was
      a director or officer of a Seller or any subsidiary of a Seller prior to
      such effective time and arising out of actions or omissions of the
      Indemnified Party in any such capacity occurring at or prior to such
      effective time (a "Claim") against any costs or expenses (including
      reasonable attorneys' fees), judgments, fines, losses, claims, damages or
      liabilities reasonably incurred in connection with any Claim, whether
      asserted or claimed prior to, at or after such effective time, to the
      fullest extent that such Seller would have been permitted under Delaware
      law, the respective charters or by-laws of such Seller or written
      indemnification agreements in effect at the date hereof, including
      provisions therein relating to the advancement of expenses incurred in the
      defense of any action or suit.

                  (ii) Any Indemnified Party wishing to claim indemnification
      under paragraph (i) of this Section 8(j) upon learning of any such Claim,
      shall promptly notify Parent thereof, but the failure to so notify shall
      not relieve Parent of any liability it may have to such Indemnified Party
      if such failure does not materially prejudice the indemnifying party. In
      the event of any such Claim (whether arising before or after the Merger 1
      Effective Time or the Merger 3 Effective Time, as the case may be), (A)
      Parent shall have the right to assume the defense thereof and Parent shall
      not be liable to such Indemnified Parties for any legal expenses of other
      counsel or any other expenses subsequently incurred by such Indemnified
      Parties in connection with the defense thereof, except that if Parent
      elects not to assume such defense, the Indemnified Parties may retain
      counsel reasonably satisfactory to Parent, and Parent shall pay reasonable
      fees and expenses of such counsel for the Indemnified Parties; provided,
      however, that Parent shall be obligated pursuant to this paragraph (ii) to
      pay for only one firm or counsel for all Indemnified Parties unless the
      use of one counsel for such Indemnified Parties would present such counsel
      with a conflict of interest, (B) the Indemnified Parties will cooperate in
      the defense of any such matter and (C) Parent shall not be liable for any
      settlement effected without its prior written consent, which consent will
      not be unreasonably withheld; and provided, further, however, that Parent
      shall not have any obligation hereunder to any Indemnified Party when and
      if a court of competent jurisdiction shall ultimately determine, and such
      determination shall have become final and non-appealable, that the
      indemnification of such Indemnified Party in the manner contemplated
      hereby is prohibited by applicable law. If such indemnity is not available
      with respect to any Indemnified Party, then Parent and the Indemnified
      Party shall contribute to the amount payable in such proportion as is
      appropriate to reflect relative faults and benefits, with any respect of
      "fault" otherwise allocable to a Seller being allocated to Parent.

                  (iii) For a period of six years after the Merger 1 Effective
      Time and the Merger 3 Effective Time, respectively, Purchasers shall
      maintain the Sellers' existing directors and officers liability insurance
      or equivalent liability insurance, which will provide coverage for those
      persons who are directors and officers of the Sellers as of such effective
      time, so long as the annual premium therefor is not in excess of 150% of
      the last annual premium paid by the Sellers prior to the date hereof.

                  (iv) In lieu of the insurance arrangement referred to in
      clause (iii) of this Section 8(j), Purchasers may, on or before the
      Closing, enter into alternative insurance arrangements, providing that
      such arrangements are approved by each of the Sellers and are no less
      advantageous to the Indemnified Parties so long as no lapse in coverage
      occurs as a result of such substitution.

                  (v) The obligations of Purchasers under this Section 8(j) are
      intended to benefit, and be enforceable against Purchasers directly by the
      Indemnified Parties, and shall be binding on all respective successors of
      Purchasers.

                                       44
<PAGE>
            (k) SHAREHOLDERS AGREEMENT; COMPLIANCE WITH THE SECURITIES ACT. Each
Seller shall each use their reasonable best efforts to cause each principal
executive officer, each director and each other person who is an Affiliate of
either Seller to deliver to Parent on or prior to the Merger 1 Effective Time
(i) a written agreement (an "AFFILIATE AGREEMENT") to the effect that such
person will not offer to sell, sell or otherwise dispose of any shares of Parent
Common Stock issued in the Mergers, except, in each case, pursuant to an
effective registration statement or in compliance with Rule 145, as amended from
time to time, or in a transaction which, in the opinion of legal counsel
satisfactory to Parent, is exempt from the registration requirements of the
Securities Act and (ii) a Shareholders Agreement. Parent shall be entitled to
place appropriate legends on the certificates evidencing any Parent Common Stock
to be received by such Affiliates pursuant to the terms of this Agreement, and
to issue appropriate stop transfer instructions to the transfer agent for the
Parent Common Stock, consistent with the terms of the Affiliate Agreements.

            (1)   CONVEST SHARES.

                  (i) TRANSFER AND ENCUMBRANCE. Edisto agrees not to transfer,
      sell, exchange, pledge or otherwise dispose of or encumber the Shares or
      any New Shares (as hereinafter defined) or to make any offer or agreement
      relating thereto, at any time prior to the Expiration Date. As used
      herein, the term "Expiration Date" shall mean the earlier to occur of (A)
      such date and time as each of the Mergers shall have become effective in
      accordance with the terms and provisions of the Merger Agreement, (B) the
      termination of this Merger Agreement in accordance with its terms.

                  (ii) NEW SHARES. Edisto agrees that any shares of capital
      stock of Convest that Edisto purchases or with respect to which Edisto
      otherwise acquires beneficial ownership after the date of this Agreement
      and prior to the Expiration Date ("NEW SHARES") shall be subject to the
      terms and conditions of this Agreement to the same extent as if they
      constituted Shares.

                  (iii) AGREEMENT TO VOTE SHARES. Unless this Merger Agreement
      is terminated pursuant to its terms, at every meeting of the stockholders
      of Convest held prior to the Merger 3 Effective Time called with respect
      to any of the following, and at every adjournment thereof, and on every
      action or approval by written consent of the stockholders of Convest with
      respect to any of the following, Edisto shall vote the Shares and any New
      Shares: (A) in favor of approval of this Agreement, the Merger 3 Articles
      and the Mergers and any matter that could reasonably be expected to
      facilitate the Mergers; and (B) against approval of any proposal made in
      opposition to the consummation of the Mergers, this Agreement or the
      Merger 3 Articles, against any merger, consolidation, sale of assets,
      reorganization or recapitalization with any party other than Parent and
      its Affiliates and against any liquidation or winding up of Convest (each
      of the foregoing is referred to as an "Opposing Proposal"). To the extent
      inconsistent with the provisions of this Agreement, Edisto hereby revokes
      any and all proxies with respect to the Shares or any other voting
      securities of Convest.

            (m) CREDIT AGREEMENT. Sellers agree, if requested by Parent, to
cooperate with Parent to cause the termination of the Amended and Restated
Secured Revolving Credit Agreement, dated June 23, 1995, by and among Convest,
Edisto E&P, BankOne, Texas, National Association, as Agent, and Compass Bank -
Houston and BankOne, Texas, National Association, as Banks, including the
termination and release of any security arrangements or other obligations of any
nature thereunder.

                  (vii) the Sellers and Purchasers shall have received an
      opinion of Coopers & Lybrand LLP, in form and substance reasonably

<PAGE>
      representations and warranties of Purchasers contained in this Agreement

      Change;

                  (iii) all governmental waivers, consents, orders, and
      approvals legally required for the consummation of the Mergers and the
      transactions contemplated hereby shall have been obtained and be in effect
      at the Closing Date except for such waivers, consents, orders and
      approvals the failure of which to have been obtained would not have,
      either individually or in the aggregate, a Material Adverse Effect, and no
      governmental authority shall have promulgated after the date hereof any
      statute, rule or regulation which, when taken together with all such
      promulgations, would cause a Material Adverse Change; and

      its respective financial advisor, dated as of the date of the definitive
      Joint Proxy Statement/Prospectus, to the effect that the consideration to
      be received in the Mergers by the respective holders of the Convest Common
      Stock and the Edisto Common Stock is fair to such holders from a financial
      point of view.

            (c) CONDITIONS TO OBLIGATION OF PURCHASERS TO EFFECT THE MERGERS.
Unless waived by Parent, the obligations of Purchasers to effect the Mergers
shall be subject to the fulfillment at or prior to the Merger 1 Effective Time

      Change;

                                       47
<PAGE>
      statute, rule or regulation which, when taken together with all such

      time by Parent in its sole discretion, to Edisto E&P's interests and
      obligations under such agreement; provided, however, that such successor
      shall not be required to assume any obligations, other than those
      currently borne by Edisto E&P, in order for Sellers to obtain such

Section 10.  TERMINATION, AMENDMENT AND WAIVER.

            (a) TERMINATION. This Agreement may be terminated at any time prior
to the Closing Date, whether before or after approval by the stockholders of the
Sellers, by the mutual written consent of the Parent and the Sellers or as
follows:

                  (i) The Sellers shall have the right to terminate this
      Agreement:

                        (A) if the representations and warranties of Purchasers
            shall fail to be true and correct in all material respects on and as
            of the date made or, except in the case of any such representations
            and warranties made as of a specified date, on and as of any
            subsequent date as if made at and as of such subsequent date and
            such failure shall not have been cured in all material respects
            within 30 days after written notice of such failure is given to
            Parent by the Sellers;

                        (B) if the Mergers are not completed by October 31, 1997
            (unless due to a delay or default on the part of a Seller);

                        (C) if any of the Mergers is enjoined by a final,
            unappealable court order not entered at the request or with the
            support of a Seller and if the Sellers shall have used reasonable
            efforts to prevent the entry of such order;

                        (D) if (w) a Seller receives an offer or proposal from
            any Potential Acquirer (excluding any Affiliate of a Seller or any
            group of which any Affiliate of a Seller is a member) with respect
            to a merger, sale of substantial assets or other business
            combination involving such Seller, (x) such Seller's Board of
            Directors determines, in good faith and after consultation with an
            independent financial advisor, that such offer or proposal (if

                                       48
<PAGE>
            consummated pursuant to its terms) would result in an Acquisition
            Transaction more favorable to such Seller's stockholders from a
            financial point of view than the relevant Merger (any such offer or
            proposal being referred to as a "SUPERIOR PROPOSAL") and resolves to
            accept such Superior Proposal, (y) the Board of Directors of the
            Seller shall conclude in good faith after consultation with its
            legal counsel that such action is necessary in order for the Board
            of Directors of the Seller to act in a manner that is consistent
            with its fiduciary obligations under applicable law and (z) the
            Seller shall have furnished the Parent with a copy of the definitive
            agreement at least five business days prior to its execution and
            Parent shall have failed within such five business day period to
            offer to amend the terms of this Agreement so that the Mergers would
            be, in the good faith determination of the Board of Directors of the
            Seller, at least as favorable to the Seller's stockholders from a
            financial point of view as the Acquisition Transaction; PROVIDED,
            HOWEVER, that such termination shall not be effective until such
            time as the payment required by Section 10(b)(ii) shall have been
            received by Parent;

                        (E) if (w) a tender or exchange offer is commenced by a
            Potential Acquirer (excluding any Affiliate of a Seller or any group
            of which any Affiliate of a Seller is a member) for all outstanding
            shares of such Seller's common stock, (x) such Seller's Board of
            Directors determines, in good faith and after consultation with an
            independent financial advisor, that such offer constitutes a
            Superior Proposal and resolves to accept such Superior Proposal or
            recommend to the stockholders that they tender their shares in such
            tender or exchange offer, (y) the Board of Directors of the Seller
            shall conclude in good faith after consultation with its legal
            counsel that such action is necessary in order for the Board of
            Directors of the Seller to act in a manner that is consistent with
            its fiduciary obligations under applicable law and (z) the Seller
            shall have furnished the Parent with a copy of the definitive
            agreement at least five business days prior to its execution and
            Parent shall have failed within such five business day period to
            offer to amend the terms of this Agreement so that the Mergers would
            be, in the good faith determination of the Board of Directors of the
            Seller, at least as favorable to the Seller's stockholders from a
            financial point of view as the Acquisition Transaction; PROVIDED,
            HOWEVER, that such termination shall not be effective until such
            time as the payment required by Section 10(b)(ii) shall have been
            received by Parent; or

                        (F) if (x) Parent fails to perform in any material
            respect any of its material covenants in this Agreement ("DEFAULT"),
            (y) Parent does not cure such Default in all material respects
            within 30 days after notice of such Default is given to Parent by
            the Sellers and (z) neither Seller is itself in Default.

                  (ii)  Parent shall have the right to terminate this Agreement:

                        (A) if the representations and warranties of the Sellers
            shall fail to be true and correct in all material respects on and as
            of the date made or, except in the case of any such representations
            and warranties made as of a specified date, on and as of any
            subsequent date as if made at and as of such subsequent date and
            such failure shall not have been cured in all material respects
            within 30 days after written notice of such failure is given to the
            Sellers by Parent;

                        (B) if the Mergers are not completed by October 31, 1997
            (unless due to a delay or default on the part of Parent);

                                       49
<PAGE>
                        (C) if any of the Mergers is enjoined by a final,
            unappealable court order not entered at the request or with the
            support of Parent and if Parent shall have used reasonable efforts
            to prevent the entry of such order;

                        (D) if the Board of Directors of a Seller shall have
            resolved to accept a Superior Proposal or shall have recommended to
            the stockholders of such Seller that they tender their shares in a
            tender or an exchange offer commenced by a third party (excluding
            any Affiliate of Parent or any group of which any Affiliate of
            Parent is a member);

                        (E) if (A) a Seller is in Default, (B) such Seller does
            not cure such Default in all material respects within 30 days after
            notice of such Default is given to such Seller by Parent, and (C)
            Parent is not itself in Default; or

                        (F) if the Sellers fail to receive the Requisite
            Stockholder Approvals.

                  (iii) As used in this Section 10(a) "GROUP" has the meaning
      set forth in Section 13(d) of the Exchange Act and the rules and
      regulations thereunder.

                  (iv) Each party (i) acknowledges that a breach of any of its
      requirements for a termination pursuant to Section 10(a)(i)(D) and
      10(a)(i)(E) will result in irreparable harm to the other party which will
      not be compensable in money damages, and (ii) agrees that such
      requirements shall be specifically enforceable and that specific
      performance and injunctive relief shall be a remedy properly available to
      the other party for a breach of such requirements. In any event, if a
      Seller enters into an Acquisition Transaction, it will immediately pay to
      Parent the sums described in Section 10(b) below.

            (b)   EXPENSES AND FEES.

                  (i) All costs and expenses incurred in connection with this
      Agreement and the transactions contemplated hereby shall be paid by the
      party incurring such expenses, except that those expenses incurred in
      connection with printing and filing the Joint Proxy Statements/Prospectus
      shall be shared equally by Parent and the Sellers.

                  (ii) The Sellers agree to immediately pay to Parent a fee
      equal to $3,000,000, if:

                        (A) either Seller terminates this Agreement pursuant to
            clause (D) or (E) of Section 10(a)(i);

                        (B) Parent terminates this Agreement pursuant to clause
            (D) of Section 10(a)(ii); or

                        (C) Parent terminates this Agreement pursuant to clause
            (F) of Section 10(a)(ii) as a result of a failure of Convest to
            receive the Requisite Stockholder Approvals.

                  (iii) Parent agrees to pay to the Sellers, as liquidated
      damages and as the sole remedy and payment for any damages, a fee equal to
      $3,000,000 if Sellers are not in breach or violation of this Agreement and
      Parent terminates this Agreement for any reason other than pursuant to
      Section 10(a)(ii).

                                       50

            (c) EFFECT OF TERMINATION. In the event of termination of this
Agreement by either Parent or the Sellers pursuant to the provisions of Section
10(a), this Agreement shall forthwith become void and there shall be no further
obligation on the part of any Party or their respective officers or directors
(except as set forth in this Section 10(c), in the second sentence of Section
8(a)(i) and in Sections 8(a)(ii) and 10(b), all of which shall survive the
termination). Nothing in this Section 10(c) shall relieve any Party from
liability for any willful or intentional breach of this Agreement; PROVIDED,
HOWEVER, that any termination of this Agreement in accordance with the
procedures and payments set forth in Section 10(b) shall relieve the terminating
Party of any such liability.

            (d) AMENDMENT. This Agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties hereto and in
compliance with applicable law. Such amendment may take place at any time prior
to the Closing Date, whether before or after approval by the stockholders of the
Sellers.

            (e) WAIVER. At any time prior to the Merger 1 Effective Time, Merger
2 Effective Time or Merger 3 Effective Time, as the case may be, the Parties
hereto may (i) extend the time for the performance of any of the obligations or
other acts of the other Parties hereto, (ii) waive any inaccuracies in the
representations and warranties contained herein or in any document delivered
pursuant thereto and (iii) waive compliance with any of the agreements or
conditions contained herein. Any agreement on the part of a Party hereto to any
such extension or waiver shall be valid if set forth in an instrument in writing
signed on behalf of such Party.

SECTION 11.  GENERAL PROVISIONS.

            (a) NON-SURVIVAL OF REPRESENTATIONS AND WARRANTIES. No
representations or warranties in this Agreement or in any instrument delivered

Agreement shall survive the Closing.

                                                                   TCW AGREEMENT

                              SHAREHOLDER AGREEMENT

      THIS SHAREHOLDER AGREEMENT (this "Agreement") is made and entered into as
of June 19, 1997 between Forcenergy Inc, a Delaware corporation ("Forcenergy"),
and each of the undersigned stockholders (individually a "Stockholder" and
collectively the "Stockholders") of Edisto Resources Corporation, a Delaware
corporation ("Edisto") or of Convest Energy Corporation, a Texas corporation
("Convest").

                                    RECITALS

      A. Concurrently with the execution of this Agreement, Forcenergy, EDI
Acquisition Corporation, a Delaware corporation and wholly owned subsidiary of
Forcenergy ("EDI"), COV Acquisition Corporation, a Texas corporation and wholly
owned subsidiary of Forcenergy ("COV"), Edisto and Convest have entered into an
Agreement and Plan of Merger, a copy of which is attached as Exhibit A hereto
(the "Merger Agreement"), which provides for the mergers (the "Mergers") of EDI
with and into Edisto and Convest with and into COV. Pursuant to the Merger
Agreement, upon consummation of the Mergers all outstanding capital stock of
Edisto and of Convest will be converted into the right to receive cash and stock
of Forcenergy and stock of Forcenergy, respectively.

      B. Each Stockholder owns the number of shares of the outstanding Common
Stock, $.01 par value per share of Edisto or Convest as is indicated on Schedule
I of this Agreement (collectively, the "Shares").

      C. The agreements of the Stockholders contained herein are in
consideration of the execution of the Merger Agreement by Forcenergy.

      D. The directors and officers of Edisto and Convest have approved the
Mergers and believe the Mergers are in the best interest of such companies and
their stockholders.

      NOW, THEREFORE, in consideration of the foregoing and subject to the terms
and conditions of the Merger Agreement the parties agree as follows:

      1. AGREEMENT TO RETAIN SHARES.

            1.1 TRANSFER AND ENCUMBRANCE. Stockholders agree not to transfer,
sell, exchange, pledge or otherwise dispose of or encumber the Shares or any New
Shares (as hereinafter defined) or to make any offer or agreement relating
thereto, at any time prior to the Expiration Date. As used herein, the term
"Expiration Date" shall mean the earlier to occur of (i) such date and time as
each of the Mergers shall have become effective in accordance with the terms and
provisions of the Merger Agreement (the "Effective Time"), (ii) the termination
of the Merger Agreement in accordance with Section 10(a)(i)(A), 10(a)(i)(B),
10(a)(i)(C), 10(a)(i)(F) or 10(a)(ii)(B) thereof or (iii) a termination of the
Merger Agreement in accordance with Section 10(a)(i)(D), 10(a)(i)(E) or

                                       -1-
<PAGE>
10(a)(ii)(D) thereof and in which Edisto's Board of Directors determines in good
faith and after consultation with an independent financial advisor that such
Superior Proposal would result in the payment of consideration valued at a
minimum of $10.95 per share to the stockholders of Edisto in exchange for all
outstanding shares of Edisto common stock.

            1.2 NEW SHARES. Stockholders agree that any shares of capital stock
of Edisto or Convest that Stockholders purchase or with respect to which
Stockholders otherwise acquire beneficial ownership after the date of this
Agreement and prior to the Expiration Date ("New Shares") shall be subject to
the terms and conditions of this Agreement to the same extent as if they
constituted Shares.

      2. AGREEMENT TO VOTE SHARES. Unless the Merger Agreement is terminated
pursuant to the provisions of Section 10(a)(i)(A), 10(a)(i)(B), 10(a)(i)(C),
10(a)(i)(F) or 10(a)(ii)(B) thereof or the conditions of Section 1.1(iii) hereof
are met, at every meeting of the stockholders of Edisto or Convest held prior to
the Effective Time called with respect to any of the following, and at every
adjournment thereof, and on every action or approval by written consent of the
stockholders of Edisto or Convest with respect to any of the following,
Stockholders shall vote the Shares and any New Shares: (i) in favor of approval
of the Merger Agreement and the Mergers and any matter that could reasonably be
expected to facilitate the Mergers; and (ii) against approval of any proposal
made in opposition to the consummation of the Mergers and the Merger Agreement,
against any merger, consolidation, sale of assets, reorganization or
recapitalization with any party other than Forcenergy and its affiliates and
against any liquidation or winding up of Edisto or Convest (each of the
foregoing is referred to as an "Opposing Proposal"). Stockholders agree not,
directly or indirectly, to solicit or encourage any offer from any party
concerning the possible disposition of all or any substantial portion of
Edisto's or Convest's business assets or a controlling equity interest in Edisto
or Convest.

      3. ADDITIONAL AGREEMENTS.

            3.1 The Stockholders hereby consent to the release by the inclusion
in any press release relating to the Mergers of the following language:

            Investment funds and accounts managed by TCW Special Credits and
            Oaktree Capital Management, LLC, which hold slightly in excess of 51
            percent of Edisto's common stock, have agreed to support the
            proposed Mergers by their willingness to vote for the transaction.
            In addition, such parties have contractually agreed not to sell 80%
            of the stock of Forcenergy received in the transaction for a period
            of six months from the consummation of the transaction.

            3.2 The Stockholder acknowledges that the terms of this Agreement
will be required to be described, and this Agreement will be required to be
filed, in certain securities law filings relating to the Mergers.

                                       -2-
<PAGE>
            3.3 To the extent inconsistent with the provisions of this
Agreement, the Stockholder hereby revokes any and all proxies with respect to
the Shares or any other voting securities of Edisto or Convest.

            3.4 Stockholder agrees not to transfer, sell, exchange, pledge or
otherwise dispose of or encumber any shares of common stock, par value $.01 per
share, of Forcenergy received pursuant to the Mergers (the "Stock") or to make
any offer or agreement relating thereto, at any time prior to 180 days from the
date that both of the Mergers shall have become effective in accordance with the
terms and provisions of the Merger Agreement; provided, however, that
notwithstanding the foregoing, Stockholder may transfer, sell, exchange, pledge
or otherwise dispose of or encumber up to 20% of the total number of shares of
Stock.

            Notwithstanding anything to the contrary set forth herein, this
Agreement shall not restrict any representative, employee or agent of the
Stockholder from acting in accordance with such person's fiduciary duties as a
director of Edisto.

      4. REPRESENTATIONS, WARRANTIES AND COVENANTS OF STOCKHOLDER. Each
Stockholder represents, warrants and covenants as to itself to Forcenergy as of
the date hereof and the Closing Date of the Mergers as follows:

            4.1 OWNERSHIP OF SHARES. Each Stockholder: (i) is the beneficial
owner of the Shares set forth on Schedule 1 hereto, which at the date of this
Agreement and at all times up until the Expiration Date will be free and clear
of any liens, claims, options, charges or other encumbrances; (ii) does not
beneficially own any shares of capital stock of Edisto or Convest other than the
Shares (excluding shares as to which Stockholder currently disclaims beneficial
ownership in accordance with applicable law); and (iii) has full power and
authority to make, enter into and carry out the terms of this Agreement. TCW
Special Credits and Oaktree Capital Management, LLC have full power and
authority to execute this Agreement on behalf of and to bind each of the
Stockholders to the terms of this Agreement.

            4.2 NO PROXY SOLICITATIONS. Unless the Merger Agreement is
terminated pursuant to the provisions of Section 10(a)(i)(A), 10(a)(i)(B),
10(a)(i)(C), 10(a)(i)(F) or 10(a)(ii)(B) thereof or the conditions of Section
1.1(iii) hereof are met, Stockholders will not, and will not permit any entity
under Stockholders' control, to: (i) solicit proxies or take part in a
solicitation of proxies with respect to an Opposing Proposal or otherwise
encourage or assist any party in taking or planning any action that would
compete with, restrain or otherwise serve to interfere with or inhibit the
timely consummation of the Mergers in accordance with the terms of the Merger
Agreement; (ii) initiate a stockholders' vote or action by written consent of
Edisto or Convest stockholders with respect to an Opposing Proposal; or (iii)
enter into any agreement with any third party substantially similar to this
Agreement with respect to any voting securities of Edisto or Convest with
respect to an Opposing Proposal.

                                       -3-
<PAGE>
            4.3 NO CLAIMS. Stockholders do not have any claims, causes of
action, disputes, receivables, right of offset, lawsuits or any other claim
whatsoever, whether contingent or otherwise, against either Edisto or Convest or
any of their respective subsidiaries, officers, directors or employees.

      5. REGISTRATION RIGHTS.

            5.1 SHELF REGISTRATION. Within 120 days of the effective date of the
Mergers, Forcenergy shall file a "shelf" registration statement to register
under the Securities Act of 1933, as amended (the "Securities Act") the sale
from time to time of the shares of Stock and use reasonable efforts to obtain
the effectiveness of such registration statement within 180 days of the
effective date of the Mergers; PROVIDED, HOWEVER, that Forcenergy may defer its
obligations under this Section 5.1 for a period of no more than 30 days if
Forcenergy would be required to prepare financial statements other than those it
customarily prepares or Forcenergy determines in its reasonable judgment that
the registration and offering would have a material adverse effect on any
material financing, acquisition, corporate reorganization or other material
corporate transaction or development involving Forcenergy that is pending at the
time and promptly gives Stockholder notice of that determination (it being
understood, however, that, in any such event, Forcenergy shall use all
reasonable efforts to minimize the length of the postponement). The provisions
of this Section 5.1 are subject to the provisions of Section 5.4.

            In the event of the issuance of any stop order suspending the
effectiveness of any registration statement or of any order suspending or
preventing the use of any prospectus or suspending the qualification of such
shares of Stock for sale in any jurisdiction, Forcenergy shall use its
reasonable efforts promptly to obtain its withdrawal.

            5.2 PIGGYBACK REGISTRATION RIGHTS. Subject to the provisions of
Section 5.4, if Forcenergy at any time proposes to register any of its common
stock under the Securities Act (other than registrations on Forms S-4 or S-8 or
any successor forms thereof or registrations of securities in connection with a
Rule 145 transaction), whether of its own accord or at the request of any holder
or holders of its securities, it shall at such time promptly after the receipt
of a request from holder(s) of its securities or its own decision to initiate a
registration (but no later than ten business days) give written notice to the
Stockholder of its intention to do so.

            Upon the written request of the Stockholders delivered to Forcenergy
within ten business days after receipt of any such notice, Forcenergy shall use
reasonable efforts (subject to the provisions of this Section 5.2) to cause all
shares of Stock, which Stockholders shall have so requested registration
thereof, to be registered under the Securities Act, all to the extent requisite
to permit the sale or other disposition by the Stockholder of such shares of
Stock; PROVIDED, HOWEVER, Forcenergy may elect not to file a registration
statement pursuant to this Section 5.2 or may withdraw any registration
statement filed pursuant to this Section 5.2 at any time prior to the effective
date hereof.

                                       -4-
<PAGE>
            If the managing underwriter for the offering advises that marketing
factors require the inclusion in such registration of some or all of the shares
of Stock sought to be registered by the Stockholders to be limited or that the
number of securities to be registered at the insistence of Forcenergy and any
other selling shareholders plus the number of shares of Stock sought to be
registered by the Stockholders should be limited due to marketing factors, the
number of shares of Stock sought to be registered by the Stockholders and such
other selling shareholders shall be reduced pro rata, based on the number of
securities sought to be registered by each Stockholder, Forcenergy or such other
selling shareholder, to the number recommended by the managing underwriter.

            In connection with any offering involving an underwriting of shares
being issued by Forcenergy, Forcenergy shall not be required to include any of
the shares of Stock in such underwriting pursuant to Section 5.2 unless the
Stockholder accepts the terms of the underwriting as agreed upon between
Forcenergy and the underwriters.

            The shares of Stock proposed to be registered under any registration
statement under Section 5.2 hereof shall be offered for sale at the same public
offering price as the shares of common stock of Forcenergy offered for sale by
Forcenergy or any other selling shareholder covered thereby.

            5.3 EXPENSES OF REGISTRATION. All expenses incurred in connection
with the registrations of shares of Stock pursuant to this Article 5, including
without limitation (i) all state registration and qualification fees, (ii) all
printing, engineering and accounting fees, (iii) one-half of the Securities and
Exchange Commission registration fee, the fee payable to the National
Association of Securities Dealers, Inc. and (iv) all fees and disbursements of
counsel for Forcenergy, shall be borne by Forcenergy; PROVIDED, HOWEVER, that
Forcenergy shall not be required to pay, and the Stockholder shall payand any
underwriter discounts, commissions, and other underwriter compensation, to the
extent such fees, discounts, commissions and compensation relate to the shares
of Stock.

            5.4 TERMINATION. Forcenergy shall not be required to maintain the
effectiveness of the registration statement contemplated by Section 5.1
following the expiration of one year from the effective date of the Mergers and
may de-register any shares of Stock covered by such registration statement after
such time. In addition, Forcenergy shall not be obligated to take any action to
effect any registration, qualification or compliance pursuant to Section 5.2,
and the provisions contained in Section 5.2 shall terminate and be of no force
and effect, following the expiration of one year from the effective date of the
Mergers.

      6. TERMINATION. Other than with respect to the provisions of Sections 3.1,
3.2 and 3.4 and the provisions of Article 5, which provisions shall survive any
termination of this Agreement, this Agreement shall terminate and shall have no
further force or effect as of the Expiration Date.

      7. MISCELLANEOUS.

            7.1 SEVERABILITY. If any term, provision, covenant or restriction of
this Agreement is held by a court of competent jurisdiction to be invalid, void
or unenforceable, then the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.

            7.2 BINDING EFFECT AND ASSIGNMENT. This Agreement and all of the
provisions hereof shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns, but, except as
otherwise specifically provided herein, neither this Agreement nor any of the
rights, interests or obligations of the parties hereto may be assigned by either
of the parties without the prior written consent of the other, except the rights
under Article 5 may be assigned if Stockholder sells all of its Shares in a
private transaction which complies with the terms of this Agreement.

            7.3 AMENDMENTS AND MODIFICATION. This Agreement may not be modified,
amended, altered or supplemented except by the execution and delivery of a
written agreement executed by the parties hereto.

that Forcenergy will be irreparably harmed and that there will be no adequate
remedy at law for a violation of any of the covenants or agreements of
Stockholder set forth herein. Therefore, it is agreed that, in addition to any
other remedies that may be available to Forcenergy upon any such violation,
Forcenergy shall have the right to enforce such covenants and agreements by
specific performance, injunctive relief or by any other means available to
Forcenergy at law or in equity.
