          under the Plan shall be deemed issued as of the Distribution Date

          (i) inform the Disbursing Agent as to the amount of properly
          surrendered Debentures and (ii) instruct the Disbursing Agent, in a
          form and manner that the Disbursing Agent reasonably determines to be
          acceptable of the names of the holders of Allowed Class 4 Claims, and
          the number of shares of New Common Stock to be issued and, distributed

          entitled to receive New Common Stock will receive the total number of
          whole shares of New Common Stock to which such Person is entitled.
          Whenever any distribution to a particular Person would otherwise call
          for distribution of a fraction of a share of New Common Stock, the
          Allowed Debenture Claim producing the de minimis distribution shall be
          cancelled and discharged, and shall be of no further force and effect.

     DISTRIBUTION RESERVE

          1.     The Disbursing Agent shall withhold the Distribution Reserve
          from the Cash, New Common Stock, or other property to be distributed
          under the Plan.  As to any Disputed Claim, upon a request for
          estimation by the Debtors or any other party in interest, the
          Bankruptcy Court shall determine what amount is sufficient to withhold
          as the Distribution Reserve.  The Debtors or any other party in
          interest may request estimation for every Disputed Claim that is
          unliquidated and the Disbursing Agent shall withhold the Distribution
          Reserve based upon the estimated amount of such Claim as set forth in
          a Final Order.  If the Debtors elect not to request such an estimation
          from the Bankruptcy Court with respect to a Disputed Claim that is
          liquidated, the Disbursing Agent shall withhold the Distribution
          Reserve based upon the face amount of such Claim.  Nothing in the Plan
          or herein shall be deemed to entitle the holder of a Disputed Claim to
          post-petition interest on such Claim and such holder shall not be
          entitled to any such interest.

            a. In the event that any matter requires approval by the
            shareholders of the Reorganized Southern Mineral prior to the
            distribution or cancellation of all shares of New Common Stock from
            the Distribution Reserve or by the Indenture Trustee, the shares of
            New Common Stock held by the Disbursing Agent or the Indenture
            Trustee shall be deemed not to have been issued, for voting purposes
            only.

            b. If practicable, the Disbursing Agent shall invest any Cash that
            is withheld as the Distribution Reserve in a manner that shall yield
            a reasonable net return, taking into account the safety of the
            investment. Any interest that is earned shall accrue to the benefit
            of and shall be paid to the Reorganized Debtors quarter annually.

(b)  Article IX.D. of the Plan is deleted in its entirety and replaced by the
     following Article IX.D.:

     DISTRIBUTIONS AFTER ALLOWANCE

               The Reorganized Debtors or the Disbursing Agent, as the case may
          be, shall make payments and distributions from the Distribution
          Reserve to each holder of a Disputed Claim that has become an Allowed
          Claim in accordance with the provisions of the Plan governing the
          Class of Claims to which such holder belongs.  On the next succeeding
          interim distribution date after the date that the order or judgment of
          the Bankruptcy Court allowing all or part of such Claim becomes a
          Final Order, the Disbursing Agent shall distribute to the holder of
          such Claim any Cash, New Common Stock, or other property in the
          Distribution Reserve that would have been distributed on the
          Distribution Date had such Allowed Claim been allowed on the
          Distribution Date.  After a Final Order has been entered, or other
          final resolution has been reached, with respect to each Disputed Claim
          (i) any New Common Stock held in the Distribution Reserve shall become
          the property of Reorganized Southern Mineral and (ii) any Cash or
          other property remaining in the Distribution Reserve shall become
          property of the Reorganized Debtors.  All distributions made under
          this Article IX.D on account

                                       6
<PAGE>

          of an Allowed Claim shall be made together with any dividends,
          payments or other distributions made on account of, as well as any
          obligations arising from, the distributed property as if such Allowed
          Claim had been an Allowed Claim on the Distribution Date.
          Notwithstanding the foregoing, the Disbursing Agent shall not be
          required to make distributions under Article IX.D more frequently than
          once every 180 days or to make any individual payments in an amount
          less than $25.00

Section 7.  Amendments to Article XIII.

(a)  Article XIII.F. of the Plan is deleted in its entirety and replaced by the
     following Article XIII.F.:

     DISCHARGE OF DEBTORS

               All consideration distributed under the Plan shall be in exchange
          for, and in complete satisfaction, settlement, discharge, and release
          of, all Claims of any nature whatsoever against the Debtors or any of
          their assets or properties, and, except as otherwise provided herein
          or in the Confirmation Order.  Upon the Consummation Date, so long as
          the Debtors have distributed the New Common Stock and the Cash Payment
          to the Indenture Trustee, the Debtors shall be deemed discharged and
          released under Section 1141(d)(1)(A) of the Bankruptcy Code from any
          and all Claims, including, but not limited to, (i) debts, demands and
          liabilities that arose before the Confirmation Date, (ii) any
          liability (including withdrawal liability) to the extent such Claims
          relate to services performed by employees of Southern Mineral prior to
          the Petition Date and that arises from a termination of employment or
          a termination of any employee or retiree benefit program regardless of
          whether such termination occurred prior to or after the Confirmation
          Date, and (iii) all debts of the kind specified in Sections 502(g),
          502(h) or 502(i) of the Bankruptcy Code, whether or not (a) a proof of
          Claim based upon such debt is filed or deemed filed under Section 501
          of the Bankruptcy Code, (b) a Claim based upon such debt is Allowed
          under Section 502 of the Bankruptcy Code, or (c) the holder of a Claim
          based upon such debt accepted the Plan.  The Confirmation Order shall
          be a judicial determination of discharge of all liabilities of the
          Debtors, subject to the Consummation Date occurring.
