ITEM 5.  OTHER EVENTS

         On October 31, 1995, Southern Mineral Corporation (the "Company")
entered into a Purchase and Sale Agreement with Stone & Webster, Incorporated
("S&W") and Stone & Webster Oil Company, Inc. ("SWOC" and together with S&W,
"Sellers").  Subject to the terms and conditions of the Purchase and Sale
Agreement, the Company will purchase certain of SWOC's oil and gas assets, and
the outstanding capital stock of three wholly-owned subsidiaries of S&W and
SWOC engaged in oil and gas related businesses, including production, marketing
and pipelines.  Consummation of these transactions (the "Closing") is scheduled
for December 22, 1995.

         The aggregate cash purchase price is $16,500,000, subject to
adjustment for production since September 1, 1995 and certain title defects in
oil and gas properties.  The Company has escrowed $1,000,000 which generally
either will be credited to the purchase price upon Closing, paid to Sellers as
liquidated damages if Buyer fails to close and Sellers are not in material
default, or repaid to Buyer if Closing does not occur because Sellers are in
default (excluding title defects that do not exceed $500,000 in the aggregate).

         This summary is qualified in its entirety by the terms and conditions
of the October 31, 1995 Purchase and Sale Agreement between the Company and
Sellers, and October 31, 1995 Escrow Agreement between Purchaser, Sellers and
Texas Commerce Bank National Association, each of which is attached hereto as
an exhibit.  The November 1, 1995 News Release of the Company concerning the
subject transactions is attached hereto as an exhibit and incorporated herein
by reference.

                          PURCHASE AND SALE AGREEMENT

         THIS PURCHASE AND SALE AGREEMENT, made and entered into as of October
31, 1995, by and among STONE & WEBSTER, INCORPORATED, a Delaware corporation
("S&W"), and STONE & WEBSTER OIL COMPANY, INC., a Texas corporation ("SWOC"),
herein sometimes jointly referred to as "Sellers", and individually as a
"Seller" on the one hand, and SOUTHERN MINERAL CORPORATION, a Nevada
corporation ("Buyer"), on the other hand,

                                  WITNESSETH:

         In consideration of the mutual benefits derived and to be derived
herefrom by each, Sellers and Buyer agree as follows:

1.       Purchase and Sale

         For the consideration and upon the terms hereinafter set forth:

                 a.       S&W agrees to sell to Buyer, and Buyer agrees to buy
         from S&W, all the outstanding shares of capital stock of San Salvador
         Development Company, Inc., a Texas corporation ("San Salvador"), and
         Spruce Hills Production Company, Inc., a Delaware corporation ("Spruce
         Hills"), wholly-owned subsidiaries of S&W.

                 b.       SWOC agrees to sell to Buyer, and Buyer agrees to buy
         from SWOC, all SWOC's oil and gas and related properties (as
         hereinafter identified) and all the outstanding shares of capital
         stock of Venture Resources, Inc., a Texas corporation ("Venture
         Resources") (such properties and stock being together herein called
         the "SWOC Assets").  Spruce Hills, San Salvador and Venture Resources
         are sometimes referred to herein as the "Corporations".

2.       Sales Price

         The aggregate sales price (the "Sales Price") for the stock of San
Salvador and Spruce Hills (to be received by S&W at the Closing) and for the
SWOC Assets (to be received by SWOC at the Closing) is $16,500,000.  Such Sales
Price is allocated for purposes of this Agreement as follows:  $1,300,000 for
the San Salvador stock, $5,500,000 for the Spruce Hills stock and $8,940,000
for the SWOC Assets other than the stock of Venture Resources and $760,000 for
the stock of Venture Resources.

3.       Earnest Money Deposit

         Contemporaneously herewith, Buyer shall deposit with Texas Commerce
Bank National Association, Houston, Texas (the "Escrow Agent"), the sum of ONE
MILLION DOLLARS ($1,000,000), in United States Dollars (which sum plus interest
earned thereon is herein called the "Earnest Money Deposit"), to be invested by
the Escrow Agent in such manner as Sellers and Buyer shall mutually agree and
instruct the Escrow Agent within three days following the date hereof (or
failing such agreement and instruction within such time then the Earnest Money
Deposit shall be invested by the Escrow Agent in such interest-bearing method
as the Escrow Agent shall deem appropriate).  If this transaction is
consummated, the Earnest Money Deposit (including interest earned thereon)
shall be paid jointly to Sellers pursuant to

<PAGE>   6
the Closing (as defined below) to be applied on the Sales Price (in such
proportion between S&W and SWOC as they shall elect), and in accordance with
the terms of the Escrow Agreement, Buyer and Seller shall so instruct the
Escrow Agent in writing at or before the Closing.  If this transaction is not
consummated, the consequences thereof and the disposition of the Earnest Money
Deposit shall be as provided in Section 12 or Section 18 hereof.

4.       Representations of S&W as to Corporate Matters

         S&W represents to Buyer as follows:

                 a.       S&W is a corporation duly incorporated and existing
         and in good standing under the laws of the State of Delaware.  San
         Salvador is a corporation duly incorporated and existing and in good
         standing under the laws of the State of Texas.  Spruce Hills is a
         corporation duly incorporated and existing and in good standing under
         the laws of the State of Delaware.  San Salvador and Spruce Hills are
         qualified to do business in each jurisdiction in which the failure to
         so qualify could have a material adverse impact on such corporations.

                 b.       S&W has all requisite power and authority to enter
         into and perform its obligations under this Agreement.

                 c.       S&W is the owner of all the issued and outstanding
         shares of capital stock of San Salvador, being 1,000 shares of common
         stock of the par value of $100 per share, fully paid and
         nonassessable.

                 d.       S&W is the owner of all the issued and outstanding
         shares of capital stock of Spruce Hills, being 1,000 shares of common
         stock without par value, fully paid and nonassessable.

                 e.       S&W has good and marketable title to such shares of
         San Salvador and Spruce Hills and owns and has the right to sell,
         transfer and assign the same to Buyer free and clear of all security
         interests, pledges and encumbrances of any kind or character.

                 f.       To the best of S&W's knowledge, there have been no
         transfers of assets by and among the Sellers or any of the
         Corporations that would violate the consistency rules established

5.       Representations of SWOC as to Corporate Matters
         
                 a.       Each of SWOC and Venture Resources is a corporation
         duly incorporated and existing and in good standing under the laws of
         the State of Texas.  SWOC is duly qualified to transact business, and
         is in good standing, in the State of Louisiana and, to best of
         Sellers' knowledge, based upon the business transacted by SWOC it is
         not required to qualify to do business in any other jurisdiction in
         which the failure to so qualify would have a material adverse effect
         on SWOC.  Each of Venture Resources and its subsidiaries is to the
         best of SWOC's knowledge qualified to do business in each jurisdiction
         in which the failure to so qualify would have a material adverse
         impact.

                                       2

                 b.       SWOC has all requisite power and authority to enter
         into and perform its obligations under this Agreement.

                 c.       SWOC is the owner of all the issued and outstanding
         shares of capital stock of Venture Resources, being 500 shares of
         common stock of the par value of $1.00 per share, fully paid and
         nonassessable.  Venture Resources is the sole owner of all of the
         capital stock of Venture Processing Company, Venture Pipeline Company,
         VenGas Pipeline Company, VenGas Marketing Company and Venture
         Distribution Company.

                 d.       SWOC has good and marketable title to such shares of
         Venture Resources and owns and has the right to sell, transfer and
         assign the same to Buyer free and clear of all security interests,
         pledges and encumbrances.

                 e.       To the best of SWOC's knowledge, there have been no
         transfers of assets by and among the Sellers or any of the
         Corporations that would violate the consistency rules established
         under U.S. Internal Revenue Code Section 338.

6.       Representations by Sellers as to Evaluated Assets

         S&W, with respect to the San Salvador Evaluated Assets and the Spruce
Hills Evaluated Assets (which terms are defined below), herein in such context
sometimes called "Seller", and SWOC, with respect to the SWOC Evaluated Assets
and the Venture Resources Evaluated Assets (which terms are defined below),
herein in such context also sometimes called "Seller", represent as follows:

                 a.       Except for the Permitted Encumbrances (defined
         below), Seller's such Evaluated Assets are free and clear of all liens
         and encumbrances.

                 b.       To Seller's knowledge, there is no litigation pending
         against Seller that would have a material adverse effect on its such
         Evaluated Assets or the ability of Seller to consummate the
         transactions contemplated by this Agreement.

                 c.       Seller has no knowledge of any operations conducted
         on its such Evaluated Assets that are in material violation of any
         applicable statute, rule or regulation (including statutes, rules and
         regulations for protection of the environment).

                 d.       Seller makes no representation of any kind with
         respect to reserve reports or other records bearing on the existence
         or extent of reserves that may or may not be recoverable from or
         attributable to its Evaluated Assets.

                 e.       The adjusted balance sheets shown on Exhibits A-2,
         A-3, and A-4 fairly and accurately present the financial condition and
         the assets and liabilities of the respective Corporations represented
         thereon as of the effective date indicated thereon.  None of the
         Corporations named in such balance sheets have indebtedness other than
         the indebtedness set forth in such balance sheets and accounts payable
         in the ordinary course of business including AFE's pursuant to this
         Agreement.


                                       3

                 f.       Neither of Sellers has incurred any liability,
         contingent or otherwise, for brokers' or finders' fees related to the
         transactions contemplated by this Agreement for which Buyer would have
         any responsibility.

                 g.       To the best of Sellers' knowledge, with respect to
         the status and operation of the Evaluated Assets:

                          (i)     None of the Evaluated Assets is affected by
                 any agreement or arrangement (including, but not limited to,
                 any "take or pay", gas balancing, pipeline balancing or other
                 prepayment agreement or production payment by reason of
                 payments made prior to the Effective Date, to deliver oil, gas
                 or related substances produced from the Evaluated Assets at
                 some future time without then or thereafter receiving full
                 payment therefor;

                          (ii)    All proceeds of production attributable to
                 the Evaluated Assets are currently being paid directly to
                 Seller or its authorized agents without the furnishing of
                 indemnity other than the customary warranty contained in the
                 division orders, transfer orders or gas sales contracts that
                 have been furnished to Buyer, and no material portion of such
                 proceeds are being held in suspense;

                          (iii)   All royalties, shut-in royalties, minimum
                 royalties, rentals and other payments due under each of the
                 Leases have been properly and timely paid, except for those
                 amounts held in suspense, to the extent that Seller is
                 obligated to make such payment under such Leases or other such
                 contractual documents; and

                          (iv)    There are no claims or liabilities which have
                 been asserted against Seller for breach of contracts which
                 affect the Evaluated Assets and no person has any call upon,
                 option to purchase or similar rights with respect to the
                 Evaluated Assets or to the production therefrom.

                 h.       To the best of Sellers' knowledge, Seller is in
         compliance with the requirements of all laws, statutes, regulations
         and orders applicable to its business and operations, noncompliance
         with which might reasonably be expected to have a material and adverse
         effect on the Seller or any of its assets.

                 i.       To the best of Sellers' knowledge, there exists no
         gas imbalances or other conditions regarding production or products
         taken or marketed from an Evaluated Asset or any portion thereof which
         could result in:

                          (i)     a portion of Seller's interest in production
                 or products therefrom being taken or delivered after the
                 Effective Date without the Buyer receiving payment therefor at
                 the price it would have received absent such imbalance;

                          (ii)    Seller or Buyer being obligated to make
                 payment to any person or entity as a result of such imbalance;
                 or

                                       4
<PAGE>   9
                          (iii)   Buyer being obligated, by virtue of any
                 prepayment arrangement, except as shown in Exhibit A-4,
                 take-or-pay agreement or similar arrangement, to deliver
                 hydrocarbons or products produced from a property at some
                 future time without then receiving full payment therefor or,
                 production being shut-in or curtailed after the Effective Date
                 due to the noncompliance with allowables or production in
                 excess of regularly scheduled allowables, production quotas,
                 proration rules or similar orders or regulations of
                 governmental authorities.

                 j.       To the best of Sellers' knowledge, all of the
         production records (and related data), revenue and cost information,
         land records, and other related documentation to which Buyer has been
         given access or will be given access before Closing, shall not be
         incorrect or inaccurate in any material respect when so furnished, and
         no documents were removed or information or documents omitted from the
         data or documentation furnished which is necessary to make the data
         furnished not misleading in any material respect.  At Closing there
         shall have been no material adverse change in the production or
         operations with respect to the Evaluated Assets other than normal
         decline.

                 k.       To the best of Sellers' knowledge, there are no
         preferential purchase rights, necessary third party consents,
         permissions or approvals required to consummate this Agreement or for
         Seller to execute and deliver this Agreement and the Conveyances.

                 l.       As to all Sellers except with respect to Spruce
         Hills, (i) there are no outstanding commitments as of the date of this
         Agreement that require drilling or reworking operations or obligations
         of Seller to make payments in connection with the Evaluated Assets
         exceeding $10,000 net to Seller for any one commitment or $25,000 net
         to Seller in the aggregate, and (ii) Seller has not incurred any
         prepaid expenses or become obligated during the period since the
         Effective Date through the date of execution of this Agreement for
         expenditures exceeding $25,000 net to Seller in the aggregate.  As to
         Spruce Hills, Exhibit C sets forth all of such outstanding 1995
         commitments as described in the previous sentence as of the date of
         this Agreement.

                 m.       To the best of Sellers' knowledge there are no
         contracts affecting the Evaluated Interests that are unduly onerous by
         industry standards or that would interfere with the normal business
         operations as contemplated by this Agreement or any document executed
         between the parties in connection with the transaction contemplated by
         this Agreement.

                 n.       To the best of Sellers' knowledge, with respect to
         the Evaluated Assets:

                          (i)     the Evaluated Assets have been used for the
                 production of oil and gas and related operations, and at no
                 time have the Evaluated Assets been used for the unlawful
                 storage or disposal of a Hazardous Substance (as defined
                 below) or as an unlawful landfill or other unlawful waste
                 disposal site which has not been remediated.  For purposes of
                 this Agreement, "Hazardous Substance" means any substance,
                 product, waste or other material of any nature whatsoever
                 which was, as of the Effective Date, listed or regulated
                 pursuant to the Comprehensive

                 tanks on the Evaluated Assets;

                          (iii)   No Evaluated Assets owned or used by Seller
                 on any real property forming a part of the Evaluated Assets
                 contains any asbestos, which is in violation of any
                 Environmental Law;

                          (iv)    None of the Evaluated Assets and none of the

                 Seller) or other personal property or improvements forming a
                 part of the Evaluated Assets contain any polychlorinated
                 biphenyls in concentrations above 50 ppm;

                          (v)     Seller has not entered into, and, to the best
                 knowledge of Seller, no predecessor to Seller has entered
                 into, or is subject to, any consent orders, decrees, or
                 judgments in existence at this time, relating specifically to
                 the Evaluated Assets, based on any Environmental Laws (as
                 defined below) that relate to the future use of any of the
                 Evaluated Assets or that require any material change in the
                 present condition of any of the Evaluated Assets.
                 "Environmental Laws" shall mean all applicable laws, statutes,
                 rules, regulations, orders, decrees and judicial
                 interpretations of the United States or of any state in which
                 any of the Evaluated Assets are located, or any other
                 governmental or quasi-governmental authority having
                 jurisdiction, that relate to the prevention, abatement or
                 elimination of pollution, or the protection of the environment

                 limitation, those relating to the generation, transportation,

                          (vi)    There are no actions, suits, claims or
                 proceedings seeking money damages, injunctive relief, remedial
                 action or remedy, pending or (to the best of Sellers'
                 knowledge) threatened, against Seller or the Evaluated Assets
                 arising from its ownership or operation of the Evaluated
                 Assets and relating to the violation of, or noncompliance
                 with, any Environmental Laws, the disposal, discharge, or
                 release of any Hazardous Substance, or the exposure of any
                 person to any other solid waste, pollutant, chemical
                 substance, noise or vibration; and

                          (vii)   Neither the execution of this Agreement nor
                 the consummation of the transactions contemplated by this
                 Agreement will violate any Environmental Law or require the
                 consent or approval of the Environmental Protection Agency or
                 any state or local agency charged with enforcing any
                 Environmental Law.

                 o.       In recognition of the fact that a third party is the
         operator of some of such Evaluated Assets, Seller's "knowledge" for
         such purposes does not include, by inference or imputation, knowledge
         of such operators.

                          (iv)    All corporate, accounting and other records,
                 including computer records, not directly related to the SWOC
                 Assets as such.

                          (v)     Any recovery from the "PFAC Litigation", as
                 more particularly provided in Section 17 (where such term is
                 defined).  Neither Buyer, nor any of the Corporations, shall
                 have any obligation for any liabilities in connection with the
                 PFAC Litigation.

                          (vi)    Any and all obligations under any
                 relationship with employees of SWOC, provided, however, that
                 Sellers shall be entitled to the upward adjustment of the Sale
                 Price as set forth in Section 15b(ii).

9.       Access to Files

         Following execution hereof, SWOC shall make available for inspection
by Buyer in SWOC's Houston office during regular office hours such lease, well,
title, production, contract, marketing and other information as is in SWOC's
files relating to the SWOC Assets and the assets of Venture Resources, San
Salvador and Spruce Hills.  It is understood that, while San Salvador and
Spruce Hills are wholly-owned subsidiaries of S&W, the files containing such
information as S&W has regarding their assets are found in the offices of

                                       8
<PAGE>   13
SWOC.  It is also understood that S&W will use its best efforts in assisting
Buyer to gain access to such title records relating to the assets of Spruce
Hills as are not found in the offices of SWOC.  Existing abstracts of title and
title opinions will not be updated by S&W or SWOC.  Until the Closing, SWOC
shall retain the original files but Buyer shall be permitted, at its own
expense, to make copies of pertinent material contained in such files, other
than geological and geophysical information.  If for any reason the Closing
does not occur, Buyer shall immediately return all such copies to SWOC.  Until
the Closing, all such files and information shall remain subject to the
existing confidentiality agreement between S&W and Buyer.

10.      Notice of Material Title Defects

                 a.       No later than December 1, 1995, Buyer shall give
         Sellers written notification of any title defects that have an effect
         on the value of the Evaluated Assets ("Material Title Defects"), as
         such values are determined pursuant to Section 11 hereof for purposes
         of adjustment.  "Title defects" shall mean a condition of title to an
         Evaluated Asset which results in a lesser Revenue Interest or a
         greater Expense Interest for such Evaluated Asset than shown in or
         used for purposes of the Reserve Report (identified in Section 11
         below) for such Evaluated Asset or which imposes on such Evaluated
         Asset a lien or encumbrance which is not a Permitted Encumbrance.
         With respect to each Evaluated Asset identified in such notice, such
         notice shall include a detailed description of the Defective Interest,
         as hereinafter defined, the basis for the defect that causes such
         interest to be treated as a Defective Interest and Buyer's calculation
         of the Allocated Value attributable to such Defective Interest.  The
         term "Defective Interest" shall mean that portion (or all) of such
         Evaluated Asset affected by such title defect.  The term "Allocated
         Value" is defined in Section 11 below.  Material Title Defects shall
         be limited to the assets evaluated in the Reserve Reports identified
         in Section 11 below (respectively herein called the "SWOC Evaluated
         Assets", the "San Salvador Evaluated Assets" and the "Spruce Hills
         Evaluated Assets" and together, with the Venture Resources Evaluated
         Assets (the "Evaluated Assets").  The term "title defects" shall not
         include the following ("Permitted Encumbrances"):

                          (i)     Liens or assessments for taxes, operating
                 costs or other sums not yet delinquent.

                          (ii)    The burdens, encumbrances and obligations
                 created by or arising under the terms of the oil and gas
                 leases or other properties included in the Evaluated Assets,
                 operating agreements, oil or gas sales contracts, gathering or
                 transportation contracts, facilities agreements and other
                 agreements relating to the Evaluated Assets or to the
                 producing, operating, transportation or marketing of
                 production therefrom, provided, that, such burdens,
                 encumbrances and obligations shall not result in either (i) a
                 lower Revenue Interest or (ii) a higher Working Interest than
                 that shown in or used in connection with the Reserve Reports.

                          (iii)   Consents by, required notices to, filings
                 with or other actions by governmental entities if same are
                 customarily obtained subsequent to sale.


                                       9
<PAGE>   14
                          (iv)    Easements, rights-of-ways, servitudes,
                 permits and other rights in or restricting surface use.

                          (v)     Governmental rules, regulations,
                 restrictions, policies and orders.

                          (vi)    Reservoir or pipeline imbalances to the
                 extent disclosed in writing to Buyer prior to the date hereof.

                          (vii)   With respect to the Spruce Hills Evaluated
                 Assets, title being held by others for the benefit of Spruce
                 Hills unless Buyer can show proof that others holding title do
                 not in fact hold for Spruce Hills, provided however, S&W
                 represents that title to the Spruce Hills Evaluated Assets is
                 held as set forth on Exhibit D.

                          (viii)  Title defects waived by Buyer.

                 b.       It shall be deemed that any SWOC Evaluated Asset is a
         Defective Interest if it is subject to a preferential purchase right
         which is exercised.  Such interest shall not be assigned to Buyer at
         the Closing and the Sales Price paid to SWOC at the Closing (unreduced
         because of such exercise) shall be reduced by the Allocated Value of
         the interest affected by the exercise of such preferential purchase
         right (or, if so assigned then, after the Closing, shall be reassigned
         by Buyer to SWOC and at the Post-Closing Settlement the Sales Price
         paid to SWOC at the Closing shall be reduced by the amount paid to
         SWOC for exercise of such preferential purchase right).

                 c.       If Buyer gives notice of a title defect and SWOC or
         S&W have been receiving the proceeds from the sale of production from
         the interest affected by such asserted title defect, then it shall be 
         presumed that there is no Material Title Defect; provided however,
         that if Buyer provides Seller with written proof that Seller does not
         have title to the interest affected by the title defect, then such
         title defect shall be deemed to be a Material Title Defect and the
         Sales Price will be adjusted in accordance with Section 11 of this
         Agreement.

                 d.       In the event at the Closing there is any litigation
         pending against either Seller that would have a material adverse
         effect on an Evaluated Asset or the ability of either Seller to
         consummate the transactions contemplated by this Agreement as to an
         immaterial part of the Evaluated Assets, or if conduct of operations
         on an Evaluated Asset is in material violation of any applicable
         statute, rule or regulation (including those for protection of the
         environment), then in any such case, at Sellers' election, Sellers
         shall have the right to (1) continue this Agreement by treating the
         affected Evaluated Assets as Defective Interests (with the
         consequences stated in Section 11 hereof) or (2) continue this
         Agreement (without adjustment) and indemnify Buyer from any loss or
         liability caused by such litigation or violation.  If, however, any
         such litigation would have a material adverse effect on the ability of
         either Seller to consummate the transactions contemplated by this
         Agreement as to a material part of the Evaluated Assets, then, at the
         election of either Sellers or Buyer, this Agreement shall terminate
         (with the consequences stated in Section 12 hereof).

11.      Adjustment for Material Title Defects

         If Buyer gives timely notice of any Material Title Defects pursuant to
Section 10 above, S&W or SWOC shall have the right thereafter until the
Post-Closing Settlement to undertake to cure same (but shall have no duty to
bring suit or spend more than an aggregate of $10,000 in doing so).  If, at the
Closing, any Material Title Defects remain uncured, this transaction shall
nevertheless be consummated at the Closing, with no adjustment to the Sales
Price for Material Title Defects at the Closing.  If, at the time of the
Post-Closing Settlement, any Material Title Defects remain uncured, the parties
shall value such uncured Material Title Defects, using as a basis the
proportionate amounts for each of the Evaluated Assets established in (a) with
respect to the SWOC Evaluated Assets and Venture Resources Evaluated Assets the
amount set forth on Exhibits E1 and E2, (b) with respect to the San Salvador
Evaluated Assets, the Future Net Income Before Income Taxes of the proved
reserves discounted at the rate of 10.00% shown for the properties identified
in the estimate of reserves, future production and income prepared by Ryder
Scott Company dated August 10, 1995, addressed to San Salvador, and (c) with
respect to the Spruce Hills Evaluated Assets, the Company share of Present
Worth Before Income Tax of the proved and probable reserves discounted at the
rate of 15% shown for the properties identified in the evaluation report by
McDaniel & Associates Consultants Ltd. dated October 3, 1995, addressed to
Spruce Hills, copies of which reports (the "Reserve Reports") are in the
possession of SWOC and available to Buyer.  Such value of Material Title
Defects, with respect to each of the Evaluated Assets, shall be apportioned to
(a) the interests in the Evaluated Assets subject to such Material Title
Defects (the "Defective Interests") and (b) the respective amounts of the Sales
Price for the SWOC Evaluated Assets or Venture Resources Evaluated Assets or
San Salvador stock or Spruce Hills stock stated in Section 2 hereof, as
follows.  If the title defect of an Evaluated Asset is a lien or encumbrance
securing money owed, the initial value of the Defective Interest for such
Evaluated Asset shall be the amount owed.  If the title defect of an Evaluated
Asset affects its revenue interest and expense interest, both in the same
proportion, then the initial value of the Defective Interest for such Evaluated
Asset shall be that fraction of the value of the affected Evaluated Asset
(using the basis from the Reserve Reports for value stated above) which the
revenue interest of the Defective Interest bears to the revenue interest of
such Evaluated Asset shown in or used for purposes of the Reserve Report.  In
order to determine the "Allocated Value" of a Defective Interest, such initial
value of the Defective Interest, with respect to a SWOC Evaluated Asset, a
Venture Resources Evaluated Asset, a San Salvador Evaluated Asset or a Spruce
Hills Evaluated Asset, shall be divided by the total such values of all the
SWOC Evaluated Assets, all the Venture Resources Evaluated Assets, all the San
Salvador Evaluated Assets or all the Spruce Hills Evaluated Assets,
respectively, and then shall be multiplied by 100% of the Sales Price allocated
herein to the SWOC Assets (other than the stock of Venture Resources, Inc.),
100% of the Sales Price allocated herein to the San Salvador stock or 98.4% of
the Sales Price allocated herein to the Spruce Hills stock and 98.7% to the
Venture Resources Stock, respectively, and the total such Allocated Values of
Evaluated Assets remaining subject to uncured Material Title Defects at the
Post-Closing Settlement shall be an adjustment to the Sales Price at the
Post-Closing Settlement as provided in Section 15 hereof.  If, however, the
title defect of an Evaluated Asset affects its revenue interest but not its
expense interest, or the reverse thereof, or disproportionately affects both,
or affects only an oil interest but not a gas interest (where there are both
for an Evaluated Asset) and if the parties are unable to agree on the Allocated
Value of such Defective Interest, the parties shall cause such initial value of
such Defective Interest to be determined (by using the foregoing standards for
determining initial values of Defective Interests to the extent pertinent) by
Ryder Scott Company (in the case of

                                       11
<PAGE>   16
the SWOC Evaluated Assets or the San Salvador Evaluated Assets) or McDaniel &
Associates Consultants Ltd. (in the case of the Spruce Hills Evaluated Assets),
in a manner consistent with their evaluations in their Reserve Report.  The
provisions of the Examples attached hereto shall be used to interpret this
Section.

12.      Conditions to Obligations of Sellers and Buyer

                 a.       If the representations of Buyer in Section 7 hereof
         are not true and correct in all material respects at the Closing,
         Sellers, at their election, shall have the right to terminate this
         Agreement.

                 b.       If the representations of (i) S&W as to Corporate
         Matters in Section 4 hereof or (ii) of SWOC as to Corporate Matters in
         Section 5 hereof, or (iii) if the representations as to Evaluated
         Assets in Section 6 hereof are not true and correct in all material
         respects at the Closing, Buyer or Sellers', at their election, shall
         have the right to terminate this Agreement; provided, however, the
         right to terminate due to the inaccuracy of the representations
         contained in Section 6 shall be limited to the circumstance in which
         the potential damage or loss relating to such inaccuracy plus the
         Sales Price Adjustment for Material Title Defects provided in Section
         11 is in excess of $500,000 and further provided that if neither party
         elects to terminate, Buyer shall receive a downward adjustment equal
         to the loss or damage.  In the event that there is an inaccuracy in
         the representations contained in Section 6 and the loss or damage
         attributable to such inaccuracy plus the Sales Price Adjustment for
         Material Title Defects provided in Section 11 is less than $500,000,
         but more than $100,000, neither Buyer nor Sellers shall be entitled to
         terminate this Agreement, however, Buyer shall be entitled to a
         downward adjustment to the Purchase Price in an amount equal to the
         sum of the loss or damage attributable to the inaccuracy of the
         representation and the adjustment to the Sales Price for Material
         Title Defects.

                 c.       In the event of termination by Sellers under Section
         12.a or by Buyer or Seller under Section 12.b, the Earnest Money
         Deposit shall be returned by the Escrow Agent to Buyer and no party
         hereto shall have any further right or duty hereunder.

13.      The Closing

                 Unless this Agreement has been terminated pursuant to Section
         10 or Section 12 hereof, the items to consummate the sales
         contemplated herein shall be delivered at closing (the "Closing") on
         December 22, 1995 (or such other date as is mutually agreed in
         writing), commencing at 10:00 a.m., at the offices of Stone & Webster
         Oil Company, Inc., 500 Dallas, Suite 2800, Houston, Texas 77002.  At
         the Closing:

                          (i)     Buyer shall deliver to the Sellers the
                 aggregate Sales Price stated in Section 2 hereof (less the
                 $1,000,000 original Earnest Money Deposit plus any interest
                 thereon), in United States Dollars immediately available
                 without deduction for collection charges or the like.

                          (ii)    S&W shall deliver to the Buyer certificates
                 for all the outstanding shares of capital stock of San
                 Salvador and Spruce Hills, and SWOC shall deliver to the Buyer
                 certificates for all the outstanding

                                       12
<PAGE>   17
                 shares of capital stock of Venture Resources, all duly
                 endorsed in blank or accompanied by stock powers duly 
                 endorsed in blank.

                          (iii)   SWOC shall deliver to the Buyer recordable
                 assignments and bills of sale of the SWOC Assets (other than
                 the stock of Venture Resources), effective with respect to
                 sales and deliveries of oil and gas at 7:00 a.m., January 1,
                 1996, subject to the Permitted Encumbrances, without warranty
                 of title, express or implied, and without any express or
                 implied warranty as to the fitness thereof for any purpose,
                 "AS IS" and "WHERE IS" and transfer orders or letters in lieu
                 thereof; provided, however, as between Buyer and Sellers, the
                 Effective Date for allocation of costs, obligations and
                 revenues shall be the Effective Date stated in Section 14.

                          (iv)    Sellers shall cause to be delivered to the
                 Buyer resignations of all employees, directors and officers of
                 San Salvador, Spruce Hills and Venture Resources and its
                 subsidiaries, effective at the close of business on December
                 31, 1995.

                          (v)     SWOC shall deliver to Buyer possession of the
                 SWOC Assets, including the SWOC offices in One Allen Center.
                 SWOC shall have the right to nonexclusive occupancy thereof
                 and access to the records therein for such period of time as
                 is necessary for SWOC to remove property not included in the
                 SWOC Assets sold to Buyer and to perform the accounting
                 necessary for the Post-Closing Settlement and for S&W and SWOC
                 to calculate taxes and close their books on this transaction;
                 provided, however, such time period shall not extend beyond
                 the date for Post-Closing Adjustments.  Such deliveries shall
                 be deemed to be effective at the close of business on December
                 31, 1995 (which shall be deemed to be the date of the
                 Closing).

                          (vi)    Sellers shall cooperate with Buyer, subject
                 to existing operating agreements, to transfer operations for
                 all wells operated by Sellers or their Corporations, including
                 the execution of P-4 forms or any other required forms.

14.      Effective Date

         If the transactions contemplated by this Agreement are consummated in
accordance with this Agreement, the ownership of the SWOC Assets, San Salvador
stock and Spruce Hills stock shall be transferred from Sellers to Buyer as
provided in Section 13 above pursuant to the Closing, as of the date of the
Closing but effective as of 7:00 a.m. on September 1, 1995 (the "Effective
Date") for purposes of allocating certain costs and revenues as set out in
Section 15 hereof.  Specifically, and not by way of limitation, for purpose of
such allocation with respect to the SWOC Assets, (a) SWOC shall bear all costs
of operations and other liabilities with respect to operations before the
Effective Date, and (b) Buyer shall be entitled to all proceeds from sales of
oil and gas produced from and after the Effective Date (or included in the
receivables on the balance sheets for SWOC as of the Effective Date) and shall
bear all costs of operations and other liabilities with respect to operations
after then, except that with respect to the period between the Effective Date
and the Closing Seller shall be liable for those liabilities arising from
Seller's wrongful conduct or the breach of any


                                       13
<PAGE>   18
representation contained in this Agreement.  The parties shall exercise their
best efforts to make adjustments to the Sales Price at the Closing and to the
extent that the foregoing matters have not been accounted for at or before the
Closing, they shall be accounted for at the Post-Closing Settlement.  Buyer
shall assume all duties relating to the SWOC Assets (including, but not limited
to, all rent and other duties of SWOC under the One Allen Center Office Lease)
and ownership of Venture Resources, San Salvador and Spruce Hills from and
after the close of business on December 31, 1995.

15.      Post-Closing Settlement

         The following adjustments shall be made to the Sales Price paid at the
Closing pursuant to a Post-Closing Settlement (the "Post-Closing Settlement")
on March 15, 1996 (or earlier as the parties may agree), by payment by Sellers
(according to their respective adjustments) to Buyer of the excess (if any) of
the downward adjustments over the upward adjustments or by Buyer to Sellers
(according to their respective adjustments) of the excess (if any) of the
upward adjustments over the downward adjustments:

                 a.       The following shall be downward adjustments in the
         Post-Closing Settlement:

                          (i)     If at the time of the Post-Closing Settlement
                 the Allocated Value of all then uncured Material Title Defects
                 (aggregated for the SWOC Evaluated Assets, the Venture
                 Resources Evaluated Assets, the San Salvador Evaluated Assets
                 and the Spruce Hills Evaluated Assets) exceeds $100,000, then
                 at the Post-Closing Settlement there shall be a downward
                 adjustment to the Sales Price received by SWOC equal to the
                 amount of the Allocated Values for all then uncured Material
                 Title Defects in the SWOC Evaluated Assets and the Venture
                 Resources Evaluated Assets (determined as provided in Section
                 11 hereof) and to the Sales Price received by S&W equal to the
                 amount of the Allocated Values for all then uncured Material
                 Title Defects in the San Salvador Evaluated Assets and the
                 Spruce Hills Evaluated Assets (determined as provided in
                 Section 11 hereof), each with interest from January 1, 1996,
                 to the date of Post-Closing Settlement at the prime rate (the
                 "Prime Rate") published in the Wall Street Journal (as it
                 fluctuates during such period).  If SWOC (with respect to any
                 of the SWOC uncured Defective Interests) or S&W (with respect
                 to any of the San Salvador or Spruce Hills Defective
                 Interests), with respect to each Defective Interest for which
                 such an adjustment is made, elects that Buyer reconvey to SWOC
                 (with respect to SWOC Defective Interests) or to S&W (with
                 respect to San Salvador or Spruce Hills Defective Interests)
                 such Defective Interests, Buyer shall make such reconveyances
                 effective as with respect to sales and deliveries of oil and
                 gas at 7:00 a.m., January 1, 1996.

                          (ii)    The proceeds (net of production taxes and
                 other deductions made by the purchasers of production)
                 received by SWOC from sale of oil and gas produced from the
                 SWOC Assets after the Effective Date and through the date of
                 the Closing shall be retained by SWOC but the amount thereof
                 shall be a downward adjustment in the

         
                                       14
<PAGE>   19
                 Post-Closing Settlement to that portion of the Sales Price
                 received by SWOC pursuant to the Closing, except that there
                 shall be no such adjustment with respect to Defective 
                 Interests reconveyed pursuant to Section 15.a(1) above.

                          (iii)   the amount of any downward adjustments
                 elsewhere provided in this Agreement.

                 b.       The following shall be upward adjustments in the
         Post-Closing Settlement to that part of the Sales Price received by
         SWOC at the Closing:

                          (i)     The lease or unit operating expenses and
                 capital expenditures paid by SWOC attributable to the SWOC
                 Assets for the period between the Effective Date and the date
                 of the Closing (including indirect or overhead charges on
                 properties operated by SWOC, at the rates charged by SWOC to
                 third-party non-operators, if any, otherwise at rates charged
                 by operators of comparable properties), except that there
                 shall be no such adjustment with respect to Defective
                 Interests reconveyed pursuant to Section 15.a(1) above.

                          (ii)    The rent paid by SWOC under the One Allen
                 Center Office Lease and all general and administrative
                 expenses (less and except any and all costs, of any nature or
                 character, related to the sale, including attorneys fees and
                 any payments or remuneration to employees in connection with
                 their termination) paid for the period between the Effective
                 Date and the date of the Closing.

                 c.       Prepayments by SWOC with respect to the SWOC Assets
         shall be prorated as of the date of the Closing, and the Sales Price
         shall be adjusted accordingly.

                 d.       The Sales Prices allocated in Section 2 to the SWOC
         Assets (insofar as the sale of the stock of Venture Resources is
         concerned) or to the San Salvador stock or the Spruce Hills stock are
         calculated as of the Effective Date (so that Buyer gets the benefit
         and bears the burden of the credits and debits after then attendant to
         the ownership of such stock), and there shall be no adjustment for
         differences in the balance sheets of Venture Resources, San Salvador
         or Spruce Hills (a copy of which are attached hereto as Exhibits "A-
         2", "A-3" and "A-4") for the period between the Effective Date and the
         Closing, except as provided in Section 15.a(1) (with respect to
         Material Title Defects) and except that the following shall apply:

                          (i)     While SWOC (with respect to Venture
                 Resources) and S&W (with respect to San Salvador and Spruce
                 Hills) have the right to dividend or assign out before the
                 Closing the excess of current assets over current liabilities
                 as of the Effective Date, and in addition the right to
                 dividend or assign out before the Closing profits realized by
                 such companies for the period after the Effective Date
                 (including, with respect to San Salvador and Spruce Hills, the
                 excess of proceeds of oil and gas produced after the Effective
                 Date over lease or unit operating expenditures and capital
                 expenditures after the Effective Date), but in
                 
                                       15
<PAGE>   20
                 each such case at the Post-Closing Settlement the amount so
                 dividended or assigned shall be a downward adjustment in the 
                 Sales Price allocated in Section 2 to the SWOC Assets (with 
                 respect to any such dividend or assignment out of Venture
                 Resources) or to S&W (with respect to any such dividend or
                 assignment out of San Salvador or Spruce Hills).

                          (ii)    SWOC shall cause Venture Resources to assign
                 to SWOC or its designee Venture Resources' rights and duties
                 in and to the PFAC Litigation as provided in Section 17.b,
                 with no adjustment in the Sales Price.

                          (iii)   If, between the Effective Date and the
                 Closing, it is necessary for SWOC (with respect to Venture
                 Resources) or S&W (with respect to San Salvador or Spruce
                 Hills) to deliver sums to such subsidiaries for current
                 expenses, then the sums so delivered (with interest at the
                 Prime Rate from the date such loan was made to the date of the
                 Post-Closing Settlement) shall be an upward adjustment to the
                 Sales Price (for SWOC or S&W, as the case may be) at the
                 Post-Closing Settlement.

                 e.       While not an adjustment to the Sales Price to SWOC,
         in the Post-Closing Adjustment, SWOC shall pay to Buyer all proceeds
         of production held in suspense by SWOC which (with the passage of
         time) would be subject to the Texas escheat laws, and Buyer shall
         assume the liability for paying such proceeds either to those entitled
         thereto or to the State Treasurer pursuant to the escheat laws.

                 f.       Sellers shall indemnify, and hold Buyer harmless from
         and against any and all claims, losses, damages, costs, expenses,
         suits, causes of action or judgments of any kind or character,
         including, but not limited to, any attorneys' fees, attributable to or
         arising out of the operation of the Evaluated Assets before the
         Effective Date. Buyer shall indemnify, and hold Seller harmless from
         and against any and all claims, losses, damages, costs, expenses,
         suits, causes of action or judgments of any kind or character,
         including, but not limited to, any attorneys' fees, attributable to or
         arising out of the operation of the Evaluated Assets on or after the
         Effective Date.

                 g.       All ad valorem taxes, real property taxes, taxes
         based on production from the Evaluated Assets, and similar obligations
         with respect to the tax period in which the affected date occurs shall
         be apportioned between Seller and Buyer as of the Effective Date based
         on the immediately preceding tax period assessment.

16.      Casualty Loss

         If, prior to the Closing, any of the Evaluated Assets is destroyed by
fire or other casualty, this transaction shall be closed notwithstanding such
loss, and Buyer may elect before the Post-Closing Adjustment one of the
following:

                 a.       To treat the property affected by such destruction as
         a Defective Interest and adjust the Sales Price in accordance with
         Section 11, in which case all sums received or receivable by SWOC, San
         Salvador, Venture Resources or Spruce Hills from

                                       16
<PAGE>   21
         third parties (including insurance proceeds) and all rights to unpaid
         awards or rights from third parties arising out such loss shall belong
         to SWOC or S&W, respectively (and, if received by San Salvador or
         Spruce Hills before the Post-Closing Settlement shall be assigned by
         them to S&W before then).

                 b.       To close without reduction of the Sales Price at the
         Closing (and without adjustment at the Post-Closing Settlement), in
         which case, with respect to the affected SWOC assets or Venture
         Resources assets, SWOC shall pay to Buyer all sums received by SWOC or
         Venture Resources from third parties (including insurance proceeds)
         and shall assign to Buyer all of SWOC's or Venture Resources right,
         title and interest in any unpaid awards or rights from third parties
         arising out of such loss, and, with respect to the affected San
         Salvador Assets and Spruce Hills assets, such companies shall retain
         such sums and all rights to such awards or rights (which will not be
         assigned by them to S&W).

17.      Covenants of Sellers Pending the Closing

                 a.       Between the date of this Agreement and the Closing,
         SWOC shall (and shall cause Venture Resources), and S&W shall cause
         San Salvador and Spruce Hills to (i) carry on its operations in
         substantially the same manner as before the date of this Agreement,
         but neither of Sellers shall have any liability to Buyer except in the
         case of such Seller's gross negligence or willful misconduct, and (ii)
         obtain from Buyer instructions, and implement such instructions, with
         respect to each Authority for Expenditure or other commitment for the
         expenditure of funds involving more than $10,000 with respect to a
         Seller or its subsidiary.  Buyer will respond within the time required
         on any Authority for Expenditure and upon the failure of Buyer to
         timely respond, Seller shall use its best judgment in making the
         required response.

                 b.       Before the Closing, SWOC shall cause Venture
         Resources to assign to SWOC or its designee all its rights in and to
         Cause No. 9300285 in the District Court of Harris County, Texas, 80th
         Judicial District, styled "Producers Financial Acceptance Corporation
         v. Enron Oil Trading & Transportation" (the "PFAC Litigation"), and in
         consideration for such assignment SWOC shall indemnify, defend and
         hold harmless Venture Resources from any liability and cost including
         attorney's fees arising out of the PFAC Litigation or prosecuting or
         defending same.

                 c.       At or before the Closing, SWOC shall assume all
         duties of Venture Resources with respect to employee benefits for the
         employees of Venture Resources (and any liability on its balance sheet
         with respect thereto shall be removed).

                 d.       Within 10 days prior to Closing, Sellers' will
         deliver to Buyer a list of all contracts that, to the best of Sellers'
         knowledge, constitute the Contracts relating to the Evaluated Assets.

                 e.       After Closing, Seller and Buyer shall execute,
         acknowledge and deliver or cause to be executed, acknowledged and
         delivered such instruments and take such other action as may be
         reasonably necessary or advisable to carry out their obligations and
         liabilities under this Agreement and under any Exhibit, document,
         certificate or other instrument delivered pursuant hereto.  Seller and
         Buyer agree to negotiate, execute, and deliver a transition services
         agreement governing the common use of

                                       17

                 a.       If at the Closing Seller is not in material default
         and Buyer should fail to pay or tender to the Seller the Sales Price
         pursuant to Section 13 hereof, in return for tender at the Closing by
         Sellers to the Buyer of the matters to be delivered by Sellers
         pursuant to Section 13 hereof, the Earnest Money Deposit (including
         interest earned thereon) shall be paid jointly to Sellers by the
         Escrow Agent upon certification to the Escrow Agent in accordance with
         the terms of the Escrow Agreement, it being agreed that actual damages
         are unascertainable and that receipt by Sellers of the Earnest Money
         Deposit is the proper measure of damages and sole remedy to which
         Sellers are entitled and is not a penalty.

                 b.       If at the Closing Buyer is not in material default
         and Sellers should fail to tender to the Buyer the matters to be
         delivered by Sellers pursuant to Section 13.a(2), (3) and (4) hereof,
         in return for payment or tender at the Closing by Buyer to the Seller
         of the Sales Price to be paid by Buyer pursuant to Section 13.a(1),
         Buyer shall be entitled as its sole right and remedy to specific
         performance; injunctive relief and any actual costs incurred in
         connection therewith (including attorneys' fees and court costs) in
         connection therewith, or, at Buyer's election, any such damages as are
         provided for at law under such circumstances, not to exceed return of
         the Earnest Money Deposit (including interest earned thereon) plus the
         lesser of (i) Buyers actual out-of-pocket costs incurred in connection
         with the transaction contemplated by this Agreement or (ii) $125,000.

19.      Miscellaneous

                 a.       This transaction involves several sales and cannot be
         severed as to less than all provided for herein without written
         consent of Sellers and Buyer.

                 b.       Sellers and Buyer shall each pay their own expenses

         Escrow Agent shall be borne one-half by Sellers and one-half by Buyer.

                 c.       Subject to the terms and conditions hereof, this
         Agreement shall be binding on and inure to the benefit of the parties
         hereto and their respective successors and assigns, provided that the

1.       SWOC Property (chosen at random) used for this example:

         Lease Name:          Land, B. M. Jr. No. 1

                   EXAMPLE OF ADJUSTMENT FOR TITLE DEFECT


1.       SWOC Property (chosen at random) used for this example:
         Lease Name:           Land, B. M. Jr. No. 1

                               (Table 55 in Ryder Scott report)

         Expense Interest:     0.160569

         Oil and Gas Revenue Interest:   0.124603

         Future Net Income Before Taxes (discounted at 10%):   $20,285

2.       Reserve Report Total Proved Value discounted @ 10% = $6,032,708

3.       Assume failure of title to an undivided 50% of SWOC's interest
         (affecting Expense and Revenue Interests in the same proportion).

4.       Initial value of Defective Interest is:

             0.0623015/0.124603 of $20,285 = $10,142.50

5.       Assume Sales Price of SWOC Assets (including Venture Resources)

              is $8,940,000.

6.       Assume total SWOC Evaluated Asset values are 90% of total SWOC Asset
         values (excluding Venture Resources).

7.       Allocated Value of this Defective Interest is:

             ($10,142.50/$6,032,708) x (90% of $8,940,000) = $13,527.35.

                               ESCROW  AGREEMENT

                                (EARNEST MONEY)


                 THIS ESCROW AGREEMENT (as the same may from time to time be
amended or modified and including any and all written instructions given to
"Escrow Agent" (hereinafter defined) pursuant hereto, this "Escrow Agreement")
is made and entered into as of October 31, 1995 by and among Southern Mineral
Corporation, a Nevada Corporation ("Buyer"), and Stone & Webster Incorporated,
a Delaware corporation, and Stone & Webster Oil Company, Inc., a Texas
corporation ("Seller", and together with Buyer, sometimes referred to
collectively as the "Other Parties"), and TEXAS COMMERCE BANK NATIONAL
ASSOCIATION, a national banking association with its principal offices in
Houston, Harris County, Texas (the "Bank").

                             W I T N E S S E T H :

                 WHEREAS, in connection with certain matters described in
Exhibit A attached hereto, Seller has requested that Buyer deposit, and Buyer
has agreed to deposit, a certain cash sum in an escrow fund to be maintained
pursuant to this Escrow Agreement; and

                 WHEREAS, Buyer and Seller have requested Bank to act in the
capacity of escrow agent under this Escrow Agreement, and Bank, subject to the
terms and provisions hereof, has agreed so to do;

                 NOW, THEREFORE, in consideration of the premises and mutual
covenants and agreements contained herein, the parties hereto hereby agree as
follows:

                 1.       Appointment of Escrow Agent.  Each of Buyer and
Seller hereby appoints the Bank as the escrow agent under this Escrow Agreement
(the Bank in such capacity, the "Escrow Agent"), and Escrow Agent hereby
accepts such appointment.

                 2.       Deposit.  Upon execution of this Escrow Agreement,
Buyer will deliver to the Escrow Agent the sum of ONE MILLION AND NO/100
DOLLARS ($1,000,000.00) (as said amount may increase or decrease as a result of
the investment and reinvestment thereof and as said amount may be reduced by
charges thereto and payments and setoffs therefrom to compensate or reimburse
Escrow Agent for amounts owing to it pursuant hereto, the "Deposit") to be held
by Escrow Agent in accordance with the terms hereof.  Subject to and in
accordance with the terms and conditions hereof, Escrow Agent agrees that it
shall receive, hold in escrow, invest and reinvest and release or distribute
the Deposit.  It is hereby expressly stipulated and agreed that all interest
and other earnings on the Deposit shall become a part of the Deposit for all
purposes, and that all losses resulting from the investment or reinvestment
thereof from time to time and all amounts charged thereto to compensate or
reimburse the Escrow Agent from time 
<PAGE>   2

to time for amounts owing to it hereunder shall from the time of such loss 
or charge no longer constitute part of the Deposit.

                 3.       Investment of the Deposit.  Escrow Agent shall invest
and reinvest the Deposit in the manner determined by Escrow Agent, unless
otherwise instructed in writing by the Other Parties.  Such written
instructions, if any, referred to in the foregoing sentence shall specify the
type and identity of the investments to be purchased and/or sold and shall also
include the name of the broker-dealer, if any, which Other Parties direct the
Escrow Agent to use in respect of such investment, any particular settlement
procedures required, if any (which settlement procedures shall be consistent
with industry standards and practices), and such other information as Escrow
Agent may require.  Escrow Agent shall not be liable for failure to invest or
reinvest funds absent sufficient written direction.  Unless Escrow Agent is
otherwise directed in such written instructions, Escrow Agent may use a
broker-dealer of its own selection, including a broker-dealer owned by or
affiliated with Escrow Agent or any of its affiliates.  It is expressly agreed
and understood by the parties hereto that Escrow Agent shall not in any way
whatsoever be liable for losses on any investments, including, but not limited
to, losses from market risks due to premature liquidation or resulting from
other actions taken pursuant to this Escrow Agreement.

                 Receipt, investment and reinvestment of the Deposit shall be
confirmed by Escrow Agent as soon as practicable by account statement, and any
discrepancies in any such account statement shall be noted by the Other Parties
to Escrow Agent within 30 calendar days after receipt thereof.  Failure to
inform Escrow Agent in writing of any discrepancies in any such account
statement within said 30-day period shall conclusively be deemed confirmation
of such account statement in its entirety.  For purposes of this paragraph, (a)
each account statement shall be deemed to have been received by the party to
whom directed on the earlier to occur of (i) actual receipt thereof and (ii)
three "Business Days" (hereinafter defined) after the deposit thereof in the
United States Mail, postage prepaid and (b) the term "Business Day" shall mean
any day of the year, excluding Saturday, Sunday and any other day on which
national banks are required or authorized to close in Houston, Texas.

                 4.       Disbursement of Deposit.  Escrow Agent is hereby
authorized to make disbursements of the Deposit only as follows:

                 (a)      To Sellers pursuant to the Closing of the Purchase
         and Sale Agreement identified in Exhibit A attached hereto.

                 (b)      To Sellers in the event of termination by Sellers
         under Section 12.a of the Purchase and Sale Agreement.

<PAGE>   3
                 (c)      To Sellers, upon failure to Buyer to pay or tender
         the Sales Price at the Closing, upon certification of Buyer's such
         default pursuant to Section 18 of the Purchase and Sale Agreement.

                 (d)      Otherwise to Buyer.

                 (e)      The foregoing disbursements shall be made upon
         receipt of written instructions signed by both Buyer and Seller and
         otherwise in form and substance satisfactory to Escrow Agent, in
         accordance with such instruction.

                 (f)      As permitted by this Escrow Agreement, to Escrow
         Agent.

                 (g)      Into the registry of the court in accordance with
         Sections 8 or 15 hereof.

Notwithstanding anything contained herein or elsewhere to the contrary, the
Other Parties hereby expressly agree that the Escrow Agent shall be entitled to
charge the Deposit for, and pay and set-off from the Deposit, any and all
amounts, if any, then owing to it pursuant to this Escrow Agreement prior to
the disbursement of the Deposit in accordance with clauses (a) through (g)
(both inclusive) of this Section 4.

                 5.       Tax Matters.  Each of the Other Parties shall provide
Escrow Agent with its taxpayer identification number documented by an
appropriate Form W 8 or Form W 9 upon execution of this Escrow Agreement.
Failure so to provide such forms may prevent or delay disbursements from the
Deposit and may also result in the assessment of a penalty and Escrow Agent's
being required to withhold tax on any interest or other income earned on the
Deposit.  Any payments of income shall be subject to applicable withholding
regulations then in force in the United States or any other jurisdiction, as
applicable.

                 6.       Scope of Undertaking.  Escrow Agent's duties and
responsibilities in connection with this Escrow Agreement shall be purely
ministerial and shall be limited to those expressly set forth in this Escrow
Agreement.  Escrow Agent is not a principal, participant or beneficiary in any
transaction underlying this Escrow Agreement and shall have no duty to inquire
beyond the terms and provisions hereof.  Escrow Agent shall have no
responsibility or obligation of any kind in connection with this Escrow
Agreement or the Deposit and shall not be required to deliver the Deposit or
any part thereof or take any action with respect to any matters that might
arise in connection therewith, other than to receive, hold, invest, reinvest
and deliver the Deposit as herein provided.  Without limiting the generality of
the foregoing, it is hereby expressly agreed and stipulated by the parties
hereto that Escrow Agent shall not be required to exercise any discretion
hereunder and shall have no investment or management responsibility and,
accordingly, shall have no duty to, or liability for its failure to, provide
investment recommendations or investment advice to the Other Parties or either
of them.




                                       3
<PAGE>   4
Escrow Agent shall not be liable for any error in judgment, any act or
omission, any mistake of law or fact, or for anything it may do or refrain from
doing in connection herewith, except for, subject to Section 7 hereinbelow, its
own willful misconduct or gross negligence.  It is the intention of the parties
hereto that Escrow Agent shall never be required to use, advance or risk its
own funds or otherwise incur financial liability in the performance of any of
its duties or the exercise of any of its rights and powers hereunder.

                 7.       Reliance; Liability.  Escrow Agent may rely on, and
shall not be liable for acting or refraining from acting in accordance with,
any written notice, instruction or request or other paper furnished to it
hereunder or pursuant hereto and believed by it to have been signed or
presented by the proper party or parties.  Escrow Agent shall be responsible
for holding, investing, reinvesting and disbursing the Deposit pursuant to this
Escrow Agreement; provided, however, that in no event shall Escrow Agent be
liable for any lost profits, lost savings or other special, exemplary,
consequential or incidental damages in excess of Escrow Agent's fee hereunder
and provided, further, that Escrow Agent shall have no liability for any loss
arising from any cause beyond its control, including, but not limited to, the
following: (a) acts of God, force majeure, including, without limitation, war
(whether or not declared or existing), revolution, insurrection, riot, civil
commotion, accident, fire, explosion, stoppage of labor, strikes and other
differences with employees; (b) the act, failure or neglect of any Other Party
or any agent or correspondent or any other person selected by Escrow Agent; (c)
any delay, error, omission or default of any mail, courier, telegraph, cable or
wireless agency or operator; or (d) the acts or edicts of any government or
governmental agency or other group or entity exercising governmental powers.
Escrow Agent is not responsible or liable in any manner whatsoever for the
sufficiency, correctness, genuineness or validity of the subject matter of this
Escrow Agreement or any part hereof or for the transaction or transactions
requiring or underlying the execution of this Escrow Agreement, the form or
execution hereof or for the identity or authority of any person executing this
Escrow Agreement or any part hereof or depositing the Deposit.

                 8.       Right of Interpleader.  Should any controversy arise
involving the parties hereto or any of them or any other person, firm or entity
with respect to this Escrow Agreement or the Deposit, or should a substitute
escrow agent fail to be designated as provided in Section 15 hereof, or if
Escrow Agent should be in doubt as to what action to take, Escrow Agent shall
have the right, but not the obligation, either to (a) withhold delivery of the
Deposit until the controversy is resolved, the conflicting demands are
withdrawn or its doubt is resolved, or (b) institute a petition for
interpleader in any court of competent jurisdiction to determine the rights of
the parties hereto.  In the event Escrow Agent is a party to any dispute,
Escrow Agent shall have the additional right to refer such controversy to
binding arbitration.  Should a petition for interpleader be instituted, or
should Escrow Agent be threatened with litigation or become involved in
litigation or binding arbitration in any manner whatsoever in connection with
this Escrow Agreement or the Deposit, the Other Parties hereby jointly and
severally agree to


                                       4
<PAGE>   5
reimburse Escrow Agent for its attorneys' fees and any and all other expenses,
losses, costs and damages incurred by Escrow Agent in connection with or
resulting from such threatened or actual litigation or arbitration prior to any
disbursement hereunder.

                 9.       Indemnification.  The Other Parties hereby jointly
and severally indemnify Escrow Agent, its officers, directors, partners,
employees and agents (each herein called an "Indemnified Party") against, and
hold each Indemnified Party harmless from, any and all expenses, including,
without limitation, attorneys' fees and court costs, losses, costs, damages and
claims, including, but not limited to, costs of investigation, litigation and
arbitration, tax liability and loss on investments suffered or incurred by any
Indemnified Party in connection with or arising from or out of this Escrow
Agreement, except such acts or omissions as may result from the willful
misconduct or gross negligence of such Indemnified Party.  IT IS THE EXPRESS
INTENT OF EACH OF BUYER AND SELLER TO INDEMNIFY EACH OF THE INDEMNIFIED PARTIES
FOR, AND HOLD THEM HARMLESS AGAINST, THEIR OWN NEGLIGENT ACTS OR OMISSIONS.

                 10.      Compensation and Reimbursement of Expenses.  The
Other Parties hereby agree to pay Escrow Agent for its services hereunder in
accordance with Escrow Agent's fee schedule as in effect from time to time and
to pay all expenses incurred by Escrow Agent in connection with the performance
of its duties and enforcement of its rights hereunder and otherwise in
connection with the preparation, operation, administration and enforcement of
this Escrow Agreement, including, without limitation, attorneys' fees,
brokerage costs and related expenses incurred by Escrow Agent.  The foregoing
notwithstanding, the Other Parties shall be jointly and severally liable to
Escrow Agent for the payment of all such fees and expenses.  In the event the
Other Parties for any reason fail to pay any such fees and expenses as and when
the same are due, such unpaid fees and expenses shall be charged to and set off
and paid from the Deposit by Escrow Agent without any further notice.

                 11.      Lien.  Each of the Other Parties hereby grants to
Escrow Agent a lien upon, and security interest in, all its right, title and
interest in and to all of the Deposit as security for the payment and
performance of its obligations owing to Escrow Agent hereunder, including,
without limitation, its obligations of payment, indemnity and reimbursement
provided for hereunder, which lien and security interest may be enforced by
Escrow Agent without notice by charging, and setting-off and paying from, the
Deposit any and all amounts then owing to it pursuant to this Escrow Agreement
or by appropriate foreclosure proceedings.

                 12.      Notices.  Any notice or other communication required
or permitted to be given under this Escrow Agreement by any party hereto to any
other party hereto shall be considered as properly given if in writing and (a)
delivered against receipt therefor, (b) mailed by registered or certified mail,
return receipt requested and postage prepaid or (c) sent by telefax machine, in
each case to the address, or telefax number, as the case may be, set forth

Except to the extent otherwise provided in the second paragraph of Section 3
hereinabove, delivery of any communication given in accordance herewith shall
be effective only upon actual receipt thereof by the party or parties to whom
such communication is directed.  Any party to this Escrow Agreement may change
the address to which communications hereunder are to be directed by giving
written notice to the other party or parties hereto in the manner provided in
this section.

                 13.      Consultation with Legal Counsel.  Escrow Agent may
consult with its counsel or other counsel satisfactory to it concerning any
question relating to its duties or responsibilities hereunder or otherwise in
connection herewith and shall not be liable for any action taken, suffered or
omitted by it in good faith upon the advice of such counsel.

                 14.      Choice of Laws; Cumulative Rights.  This Escrow
Agreement shall be construed under, and governed by, the laws of the State of
Texas, excluding, however, (a) its choice of law rules and (b) the portions of
the Texas Trust Code Sec. 111.001, et seq. of the Texas Property Code
concerning fiduciary duties and liabilities of trustees.  All of Escrow Agent's
rights hereunder are cumulative of any other rights it may have at law, in
equity or otherwise.  The parties hereto agree that the forum for resolution of
any dispute arising under this Escrow Agreement shall be Harris County, Texas,
for purposes of their Agreement, and each of the Other Parties hereby consents,
and submits itself, to the jurisdiction of any state or federal court sitting
in Harris County, Texas, for such purpose.

                 15.      Resignation.  Escrow Agent may resign hereunder upon
ten (10) days' prior notice to the Other Parties.  Upon the effective date of
such resignation, Escrow Agent shall deliver the Deposit to any substitute
escrow agent designated by Other Parties in writing.  If the Other Parties fail
to designate a substitute escrow agent within ten (10) days after the giving of
such notice, Escrow Agent may institute a petition for interpleader.  Escrow
Agent's sole responsibility after such 10-day notice period expires shall be to
hold the Deposit (without any obligation to reinvest the same) and to deliver
the same to a designated substitute escrow agent, if any, or in accordance with
the directions of a final order or judgment of a court of competent
jurisdiction, at which time of delivery Escrow Agent's obligations hereunder
shall cease and terminate.

                 16.      Assignment.  This Escrow Agreement shall not be
assigned by either of the Other Parties without the prior written consent of
Escrow Agent (such assigns of the Other Parties to which Escrow Agent consents,
if any, and Escrow Agent's assigns being hereinafter referred to collectively
as "Permitted Assigns").

                 17.      Severability.  If one or more of the provisions
hereof shall for any reason be held to be invalid, illegal or unenforceable in
any respect under applicable law, such invalidity, illegality or
unenforceability shall not affect any other provisions hereof, and this Escrow
Agreement shall be construed as if such invalid, illegal or unenforceable
provision had never been contained herein, and the remaining provisions hereof
shall be given full force and effect.

                 18.      Termination.  This Escrow Agreement shall terminate
upon the disbursement, in accordance with Sections 4 or 15 hereof, of the
Deposit in full; provided, however, that in the event all fees, expenses, costs
and other amounts required to be paid to Escrow Agent hereunder are not fully
and finally paid prior to termination, the provisions of Section 10 hereof
shall survive the termination hereof and, provided further, that the last two
sentences of Section 8 hereof and the provisions of Section 9 hereof shall, in
any event, survive the termination hereof.

                 19.      General.  The section headings contained in this
Escrow Agreement are for reference purposes only and shall not affect in any
way the meaning or interpretation of this Escrow Agreement.  This Escrow
Agreement and any affidavit, certificate, instrument, agreement or other
document required to be provided hereunder may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which taken
together shall constitute but one and the same instrument.  Unless the context
shall otherwise require, the singular shall include the plural and vice versa,
and each pronoun in any gender shall include all other genders.  The terms and
provisions of this Escrow Agreement constitute the entire agreement among the
parties hereto in respect of the subject matter hereof, and neither the Other
Parties nor Escrow Agent has relied on any representations or agreements of the
other, except as specifically set forth in this Escrow Agreement.  This Escrow
Agreement or any provision hereof may be amended, modified, waived or
terminated only by written instrument duly signed by the parties hereto.  This
Escrow Agreement shall inure to the benefit of, and be binding upon, the
parties hereto and their respective heirs, devisees, executors, administrators,
personal representatives, successors, trustees, receivers and Permitted
Assigns.  This Escrow Agreement is for the sole 


                                      8
<PAGE>   9

and exclusive benefit of the Other Parties and the Escrow Agent, and nothing 
in this Escrow Agreement, express or implied, is intended to confer or shall 
be construed as conferring upon any other person any rights, remedies or any
other type or types of benefits.

                 20.      As between Seller and Buyer, nothing herein shall
alter their respective rights and duties under the Purchase and Sale Agreement.

                 IN WITNESS WHEREOF, the parties hereto have executed this
Escrow Agreement to be effective as of the date first above written.

           New Account Acceptance Fee                               $  500.00
                    Payable Upon Account Opening

           Minimum Administrative Fee                               $3,000.00
                    Payable Upon Account Opening and
                    in Advance for each year in which
                    we act as Escrow Agent
</TABLE>

A New Account Acceptance Fee will be charged for the Bank's review of the
Escrow Agreement along with any related account documentation.  A one (1) year
Minimum Administration Fee will be assessed for any account which is funded.
The account will be invoiced in the month in which the account is opened and
annually thereafter.  Payment of the invoice is due 30 days following receipt.

The Administrative Fee will cover a maximum of fifteen (15) annual
administrative hours for the Bank's standard Escrow services including account
setup, safekeeping of assets, investment of funds, collection of income and
other receipts, preparation of statements comprising account activity and asset
listing, and distribution of assets in accordance with the specific terms of
the Escrow Agreement.

Extraordinary Services:

Any additional services beyond our standard services as specified above, such
as annual administrative activities in excess of fifteen (15) hours and all
expenses including attorney's fees will be considered extraordinary services
for which related costs, transaction charges, and additional fees will be
billed at the Bank's standard rate.

Modification of Fees:

Circumstances may arise necessitating a change in the foregoing fee schedule.
The Bank will attempt at all times, however, to maintain the fees at a level
which is fair and reasonable in relation to the responsibilities assumed and
the duties performed.

        To avoid any confusion, I have attached a copy of the page 10 from your
fax to Butler & Binion of this afternoon wherein the appropriate fund has been
noted.

        Also enclosed please find the three Taxpayer Identification Number

        We will fax this letter with attachments to expedite the process and
likewise courier a hard copy.

                                        Yours very truly,

                          SOUTHERN MINERAL CORPORATION
                         ANNOUNCES $16,500,000 PURCHASE

         Houston, November 1, 1995 -- Southern Mineral Corporation (the
"Company") announced today that it has agreed to purchase certain oil and gas
assets and subsidiaries of Stone & Webster, Incorporated ("S&W").  The cash
purchase price is $16.5 million.   The Company estimates proven reserves of
approximately one million barrels of oil and 14.5 billion cubic feet of natural
gas are included in the sale, in addition to pipeline and gathering systems.
The acquisition includes the oil and gas interests owned by Stone & Webster Oil
Company, Inc., S&W's Houston based oil and gas operating subsidiary, and the
stock of three direct or indirect subsidiaries of S&W.  One subsidiary is a
domestic corporation that owns interests in 1,200 wells located in Canada.
Another subsidiary holds interests in ten pipeline and gathering systems
located in Oklahoma, Texas and Louisiana.  A third subsidiary owns interests in
approximately 270,000 gross mineral acres together with associated producing
royalties.

         "This acquisition provides Southern Mineral Corporation with another
building block to work from," said Steven Mikel, President.  "This fits well
with our strategy to acquire and exploit oil and gas properties, since there is
significant potential beyond the existing proven asset base to build upon."
The transaction is scheduled to close by year end, subject to satisfaction of
customary closing conditions.  The Company intends to finance the acquisition
with internally generated funds and debt financing.

         Southern Mineral Corporation is an oil and gas acquisition,
exploration and production company that is listed on The NASDAQ SmallCap Market
under the trading symbol SMIN.
