Dear Limited Partner:

      Enclosed is a proxy  statement  and related  information  pertaining  to a
proposal to sell all of the Partnership's  properties and dissolve and liquidate
the  Partnership.  In order for the sale and liquidation to take place,  Limited
Partners holding a majority of the outstanding Units must approve this proposal.
The Managing General Partner  recommends that you vote in favor of such sale and
liquidation for a number of reasons.

      Swift Energy Managed Pension Assets Partnership  1990-D,  Ltd. has been in
existence  for over six years,  and most of the  properties  underlying  its net
profits interest were purchased by 1991. All economically  feasible  enhancement
opportunities  have  already been  implemented  by the  Partnership's  companion
partnership  on the  properties  in which  the  Partnership  owns  non-operating
interests.  Consequently, the Partnership's interest in proved reserves that can
be produced without requiring  further  expenditures is quite low. Thus, even if
oil and gas  prices  were  unusually  high,  there  would be no impact  upon the
Partnership's  ultimate  economic  performance.  To  continue  operation  of the
Partnership  means that  Partnership  administrative  expenses (such as costs of
audits,  reserve reports,  and Securities and Exchange Commission  filings),  as
well as the cost of operating the  properties in which the  Partnership  owns an
interest, will continue while revenues decrease, which may decrease the ultimate
funds available for Limited Partners. Liquidation of the Partnership's remaining
assets  at this time is  likely  to  result  in a  greater  percentage  of sales
proceeds being paid to Limited  Partners,  rather than being used to fund future
general and  administrative  and operating  expenses,  and will  accelerate  the
receipt by the partners of the remaining cash value of the Partnership.

      If Limited Partners holding a majority of the Units approve this proposal,
the  Managing  General  Partner  will  attempt  to  complete  the  sale  of  all
Partnership properties by the end of 1997.

      Included  in  this  package  are  the  most  recent  financial  and  other
information prepared regarding the Partnership. If you need any further material
or have  questions  regarding  this  proposal,  please  feel free to contact the
Managing General Partner at (800) 777-2750.

      We urge you to complete your Proxy and return it immediately, as your vote
is  important in reaching a quorum  necessary to have an effective  vote on this
proposal.  Enclosed  is a  green  Proxy,  along  with  a  postage-paid  envelope
addressed to the Managing  General  Partner for your use in voting and returning
your Proxy.
Thank you very much.

          Swift Energy Managed Pension Assets Partnership 1990-D, Ltd.

                    ----------------------------------------
                                 PROXY STATEMENT
                    ----------------------------------------

                                     SUMMARY

      This Proxy  Statement is being provided by Swift Energy  Company,  a Texas
corporation  (the  "Managing  General  Partner") in its capacity as the Managing
General Partner of Swift Energy Managed Pension Assets Partnership  1990-D, Ltd.
a Texas limited partnership (the "Partnership"),  to holders of units of limited
partnership interests representing an initial investment of $100 per Unit in the
Partnership  (the  "Units").  This Proxy  Statement  and the enclosed  proxy are
provided  for  use at a  special  meeting  of  limited  partners  (the  "Limited
Partners"),  and any  adjournment of such meeting (the  "Meeting") to be held at
16825 Northchase  Drive,  Houston,  Texas, at 4:00 p.m. Central Time on Tuesday,
September  30, 1997.  The Meeting is called for the purpose of  considering  and
voting  upon a  proposal  to (a) sell  substantially  all of the  assets  of the
Partnership (consisting of its net profits interest),  and (b) dissolve, wind up
and terminate the Partnership (the "Proposal"), in accordance with the terms and
provisions of Article XVI of the  Partnership's  Limited  Partnership  Agreement
dated  December 31, 1990 (the  "Partnership  Agreement"),  and the Texas Revised
Limited Partnership Act (the "Texas Act"). This Proxy Statement and the enclosed
proxy are first being mailed to Limited Partners on or about August 19, 1997.

      Under Article XVI.C of the Partnership Agreement,  the affirmative vote of
Limited Partners holding at least 51% of the Units then held by Limited Partners
as of the Record Date (as  defined) is required  for  approval of the  Proposal.
Each Limited  Partner  appearing on the  Partnership's  records as of August 15,
1997 (the "Record  Date"),  is entitled to notice of the Meeting and is entitled
to one vote for each Unit held by such Limited  Partner.  Under  Article XX.H of
the Partnership Agreement,  the General Partners may not vote any Units owned by
them  for  matters  such  as  the  Proposal.   VJM  Corporation,   a  California
corporation, the Special General Partner of the Partnership,  owns a 1% interest
in the Partnership as a General Partner, but owns no Units. The Managing General
Partner currently owns approximately 4.14% of all outstanding Units.  Therefore,
the  affirmative  vote of holders of 51% of the  remaining  Units is required to
approve the proposed sale.

      The working  interest in the producing oil and gas properties in which the
Partnership  owns the  Property  Interests is owned by an  affiliated  companion
partnership,   Swift  Energy  Income  Partners  1990-D,   Ltd.  (the  "Operating
Partnership"). The Partnership's assets consist of a net



                                        1

<PAGE>



profits  interest  that  covers  multiple  working  interests,  and which may be
divided  into  multiple  net  profits  interests  if the  Operating  Partnership
separately  sells  one or  more of its  working  interests  burdened  by the net
profits  interest (the "Property  Interests").  Upon approval of the Proposal by
the Limited Partners, the Managing General Partner intends to sell substantially
all of  the  Partnership's  Property  Interests,  together  with  the  Operating
Partnership's  working interests in the same properties,  in a sale or series of
sales,  use the proceeds to pay or provide for the payment of  liabilities,  and
then  wind  up  the  affairs  of the  Partnership.  The  Partnership's  Property
Interests  currently cover 70 wells. The total PV-10 value of the  Partnership's
remaining  reserves as of December 31, 1996 was $560,688.  The most  significant
property  owned by the  Partnership  is the Velrex Field in  Schleicher  County,
Texas,  which accounts for  approximately  35% of the value of the Partnership's
remaining reserves.  During 1996, approximately 78% of the Partnership's revenue
was  attributable  to natural  gas  production.  For more  information,  see the
attached Annual Report on Form 10-K for the year ended December 31, 1996 and the
Form 10-Q for the second quarter of 1997.

      It is highly likely that the Property  Interests  will be sold in a series
of sales  rather than in a single  transaction.  The  Managing  General  Partner
anticipates that most of the  Partnership's  Property  Interests will be sold in
auctions (together with the working interest owned by the Operating Partnership)
conducted by the Oil & Gas Asset Clearinghouse (the "O&G  Clearinghouse"),  or a
similar company engaged in auctions of oil and gas properties,  although some of
the Partnership's Property Interests may be sold in negotiated transactions. The
Managing General Partner will not begin the sales process until the Proposal has
been approved by the Limited  Partners.  The Managing  General Partner is asking
for  approval of the  Proposal  prior to  offering  the  Partnership's  Property
Interests   for  sale  to  avoid  delay  in  selling  the  Property   Interests.
Furthermore,  as the  Managing  General  Partner  must  sell  the  Partnership's
Property  Interests  in its oil and gas  properties  together  with the  working
interests  in those same  properties  owned by the  Operating  Partnerships  and
several other  Partnerships  which it manages,  solicitation of approval of each
purchase offer from all of the partnerships would be impractical.

       It is possible,  though unlikely, that less than all of the Partnership's
Property  Interests  will be sold.  See "The  Proposal--Steps  to Implement  the
Proposal--Negotiated  Sale." The Managing  General Partner  anticipates that the
majority  of  sales  will be made by the end of 1997.  The  sale of  Partnership
Property  Interests  that  account for at least 662/3% of the total value of the
Partnership   Property   Interests  will  cause  the   Partnership  to  dissolve
automatically  under the terms of the  Partnership  Agreement and the Texas Act.
Any  Partnership  Property  Interests  that are not sold at auction  may be sold
pursuant to negotiated sales to third parties.

      Currently there are no buyers for the Property  Interests and the price at
which  they  will be sold  has not yet been  determined.  The  Managing  General
Partner  cannot  accurately  predict the prices at which the Property  Interests
ultimately   will  be  sold.   See  "The   Proposal--Estimates   of  Liquidating
Distribution  Amount."  In  addition  to the  foregoing,  there  are some  risks
involved in the Proposal. See "Risk Factors."

            THE PROPOSAL INVOLVES CERTAIN RISKS. SEE "RISK FACTORS."

o     If the  Proposal  is  approved,  the  Limited  Partners  will  not have an
      opportunity to approve the specific  terms of any  particular  sale of the
      Property Interests.

o     Currently there are no buyers for the Property  Interests and the price at
      which they will be sold has not yet been determined.  The Managing General
      Partner  cannot  accurately  predict  the  prices  at which  the  Property
      Interests ultimately will be sold.

o     No minimum prices will be established for most of the Property  Interests,
      so there is no guarantee  that the Property  Interests  will be sold at or
      above their fair market value.

o     The sale of the Property Interests is dependent upon the simultaneous sale
      of the  Operating  Partnership's  interest  in the  same  properties.  The
      failure  of the  Operating  Partnership  to  approve  the  proposal  could
      significantly  adversely affect the likelihood of the sale of the Property
      Interests.

o     If  the  Proposal  is  adopted,   the  receipt  of  a  final   liquidating
      distribution   or  the   amount   thereof   is  not   assured.   See  "The
      Proposal--Estimates of Liquidating Distribution Amount."

      If the Proposal is not approved by Limited Partners holding 51% or more of
the Units held by Limited  Partners,  the Partnership will continue to exist. In
that event,  however,  due to the  expected  decline in  revenues,  the Managing
General Partner estimates that a portion of the Partnership's Property Interests
ranging from an average of 10% to 15% will need to be sold each year in order to
cover future direct costs, operating costs and administrative costs.

      The Managing  General Partner  receives  operating fees for wells in which
the  Partnership has a net profits  interest and for which the Managing  General
Partner or its affiliates serve as operator.  It is anticipated that, due to the
sale of interests in wells by the Operating  Partnership,  the Managing  General
Partner  will no longer serve as operator for a number of the wells in which the
Partnership has a net profits interest.  To the extent that the operator changes
because of a change in ownership of the properties, the Managing General Partner
will lose the revenues it  currently  earns as  operator.  The Managing  General
Partner believes,  however,  that it will be positively  affected,  on the other
hand, by liquidation of the Partnership,  on the basis of its ownership interest
in the Partnership.  See "The  Proposal--Estimates  of Liquidating  Distribution
Amount," and "The Proposal--Impact on the Managing General Partner."

            LIMITED PARTNERS ARE URGED TO COMPLETE, SIGN AND DATE THE
             ENCLOSED PROXY AND TO RETURN IT TO THE MANAGING GENERAL
                                PARTNER NO LATER
                            THAN SEPTEMBER 15, 1997.

Mcf of natural gas.

Mmbtu means million British Thermal Units, which is a heating equivalent measure
for natural gas.

Net Profits  Interest  means an interest in oil and gas property  which entitles
the owner to a specified  percentage  share of the Gross  Proceeds  generated by
such property, net of aggregate operating costs. Under the NP/OR Agreement,  the
Partnership  receives  a  Net  Profits  Interest  entitling  it  to a  specified
percentage  of the  aggregate  Gross  Proceeds  generated by, less the aggregate
operating  costs  attributable  to,  those  depths of all  Producing  Properties
acquired  pursuant to such agreement that are evaluated at the respective  dates
of acquisition to contain Proved  Reserves,  to the extent such depths  underlie
specified surface acreage.

NP/OR  Agreement means the form of Net Profits and Overriding  Royalty  Interest
Agreement  entered into  between the  Partnership  and an Operating  Partnership
pursuant to which the Partnership acquired a Net Profits Interest, or in certain
instances various Overriding Royalty Interests,  from the Operating  Partnership
in a group of  Producing  Properties.  The  Working  Interest  in such  group of
properties is held by the Operating Partnership.

PV-10 Value means the  estimated  future net  revenue to be  generated  from the
production  of proved  reserves  discounted  to  present  value  using an annual
discount rate of 10%; these amounts are  calculated net of estimated  production
costs and future  development  costs,  using  prices and costs in effect as of a
certain date,  without  escalation  and without  giving  effect to  non-property
related  expenses  such as general and  administrative  expenses,  debt service,
future income tax expense or depreciation, depletion and amortization.

Producing Properties means Properties (or interests in properties) producing oil
and gas in commercial  quantities,  or containing  shut-in wells capable of such
production,  or  properties  which are  acquired  as an  incidental  part of the
acquisition of such properties.  Producing  Properties shall include  associated
well machinery and equipment gathering systems, storage facilities or processing
installations or other equipment and property associated with the production and
field  processing of oil or gas.  Interests in Producing  Properties may include
Working Interests,  production payments,  Royalty Interests,  Overriding Royalty
Interest,  Net Profits Interests,  and other nonoperating  interests.  Producing
Properties may include gas gathering lines or pipelines. The geographical limits
of a Producing Property may be enlarged

or contracted on the basis of  subsequently  acquired  geological data to define
the productive  limits of a reservoir,  or as a result of action by a regulatory
agency employing such criteria as the regulatory agency may determine.

Proved  Reserves means those  quantities of crude oil,  natural gas, and natural
gas liquids which,  upon analysis of geologic and engineering  data, appear with
reasonable  certainty  to be  recoverable  in the future  from known oil and gas
reservoirs under existing economic and operating conditions. Proved Reserves are
limited to those  quantities of oil and gas which can be reasonably  expected to
be  recoverable  commercially  at  current  prices  and  costs,  under  existing
regulatory  practices  and with  existing  conventional  equipment and operating
methods.

Royalty  Interest means a fractional  interest in the gross  production,  or the
Gross Proceeds therefrom,  of oil and gas and other minerals under a lease; free
of any expenses of exploration, development, operation and maintenance.

Working  Interest  means the  operating  interest  under an oil, gas and mineral
lease or other  property  interest  covering a specific tract or tracts of land.
The owner of a Working  Interest has the right to explore for, drill and produce
the oil, gas and other minerals covered by such lease or other property interest
and the obligation to bear the costs of exploration,  development,  operation or
maintenance applicable to his interest.

                               GENERAL INFORMATION

Documents Included

      The  Partnership's  Annual Report on Form 10-K for the year ended December
31, 1996 and its  quarterly  report on Form 10-Q for the second  quarter of 1997
are included with this Proxy Statement and incorporated herein by reference. See
"Incorporation  of Certain  Information  By  Reference  and  Attachment  of Such
Information Hereto." Additionally, a reserve report dated May 20, 1997, prepared
as of December 31,  1996,  and audited by H. J. Gruy &  Associates,  is attached
hereto.

Vote Required

      According  to the  terms of the  Partnership  Agreement,  approval  of the
Proposal  requires  the  affirmative  vote by the holders of at least 51% of the
Units held by Limited  Partners.  Therefore,  an abstention by a Limited Partner
will have the same effect as a vote against the Proposal.  This  solicitation is
being made for votes in favor of the Proposal  (which will result in liquidation
and  dissolution).  As of the Record Date,  28,089.79 Units were outstanding and
were held of record by 277 Limited  Partners  (excluding  the  Managing  General
Partner's  Units).  Each  Limited  Partner is entitled to one vote for each Unit
held in his  name on the  Record  Date.  Accordingly,  the  affirmative  vote of
holders of at least  14,325.79  Units is required to approve the  Proposal.  The
Managing General Partner holds 1,214 Units, but, in accordance with Article XX.H
of the  Partnership  Agreement,  the Managing  General  Partner may not vote its
Units. The Managing  General  Partner's  non-vote,  in contrast to abstention by
Limited Partners, will not affect the outcome,  because for purposes of adopting
the Proposal its Units are excluded from the total number of voting Units.

      The Limited  Partners  should be aware that once they approve the Proposal
pursuant to this Proxy  Solicitation,  they will have no opportunity to evaluate
the actual terms of any specific purchase offers for the Partnership's  Property
Interests. See "The Proposal - General" herein. See "The Proposal -- Reasons for
the Proposal" and "The Partnership -- Transactions  Between the Managing General
Partner and the Partnership." Proxies; Revocation

      If a proxy is properly signed and is not revoked by a Limited Partner, the
Units it represents  will be voted in accordance  with the  instructions  of the
Limited Partner. If no specific  instructions are given, the Units will be voted
FOR the Proposal.  A Limited  Partner may revoke his proxy at any time before it
is voted at the Meeting.  Any Limited Partner who attends the Meeting and wishes
to vote in person  may  revoke  his  proxy at that  time.  Otherwise,  a Limited
Partner must advise the Managing  General  Partner of revocation of his proxy in
writing,  which  revocation must be received by the Managing  General Partner at
16825  Northchase  Drive,  Suite 400,  Houston Texas 77060 prior to the time the
vote is taken.

Dissenters' Rights

      Limited  Partners are not entitled to any dissenters' or appraisal  rights
in connection with the approval of the Proposal. Dissenting Limited Partners are
protected under state law by virtue of the fiduciary duty of general partners to
act with prudence in the business affairs of the Partnership.

Payment of Liquidating Distributions

      Following  the approval of the Proposal at the Meeting,  Limited  Partners
will receive a final  liquidating  distribution  in cash from the Partnership as
soon as practicable after the affairs of the Partnership have been wound up. The
Managing  General  Partner  expects  that such  payment will be made by year-end
1997. It will not be necessary for Limited Partners to surrender any certificate
or other documents  representing their ownership of Units.  Payment will be made
to each Limited Partner identified on the Partnership's records as of the Record
Date, or, upon appropriate  written  instruction from a Limited Partner,  to his
assignee.

Solicitation

      The  solicitation is being made by the  Partnership.  The Partnership will
bear  the  costs  of  the  preparation  of  this  Proxy  Statement  and  of  the
solicitation  of proxies  and such costs will be  allocated  90% to the  Limited
Partners  and  10% to  the  General  Partners  with  respect  to  their  general
partnership  interests pursuant to Article  VIII.A(iv).  As the Managing General
Partner  holds  approximately  4.14% of the Units held by all Limited  Partners,
4.14% of the costs borne by the Limited  Partners  will be borne by the Managing
General  Partner,  in  addition  to its  portion  borne  as a  General  Partner.
Solicitations  will be made primarily by mail. In addition to  solicitations  by
mail,  a number of regular  employees of the  Managing  General  Partner may, if
necessary  to ensure the presence of a quorum,  solicit  proxies in person or by
telephone.  The Managing  General  Partner also may retain a proxy  solicitor to
assist in  contacting  brokers or Limited  Partners to  encourage  the return of
proxies,  although  it does not  anticipate  doing so.  The costs of this  proxy
solicitation,  including  legal and accounting  fees and expenses,  printing and
mailing costs, and related costs are estimated to be approximately $20,000.

                                  RISK FACTORS

      A Limited  Partner  considering  whether to vote in favor of the  Proposal
should  give  careful  consideration  to the  risks  involved,  including  those
summarized below:

Uncertainty of Liquidating Distributions

      While the Managing General Partner is not aware of any unknown liabilities
at this time,  should any unexpected  liabilities  come to light prior to making
the final liquidating distribution, such liabilities could significantly reduce,
or eliminate altogether, such final distribution.



                                        7

Undetermined Sales Prices; Volatility of Oil and Gas Prices

      Limited  Partners  will not have an  opportunity  to approve the  specific
terms of any particular  sale of the Property  Interests and  anticipated  sales
prices for the  Property  Interests  may not be  achieved.  Should  domestic gas
prices  strengthen  after  the sales of the  assets,  it is  possible  that more
advantageous sales prices for the properties might have been realized at a later
date.

Dependence on Operating Partnership

      If the  Partnership  approves the proposal to sell its  properties but the
Operating  Partnership  does not approve the sale of its Property  Interests and
actually sell its interests in the same properties, then the Partnership will be
forced to sell its net  profits  interest  as a single  property  (or  undivided
interests therein). The purchaser or purchasers would have no control as working
interest owners, as the working interest will still be retained by the Operating
Partnership.  Because  this may  affect  the  saleability  of the  Partnership's
Property  Interests,  it may be necessary  for the Managing  General  Partner to
purchase  the  Partnership's  interests  in  such  properties.   Therefore,  the
likelihood of sale of the Partnership's Property Interests will be significantly
affected  by  the  ability  of  the  Partnership  and  its  companion  Operating
Partnership to sell their ownership  interests in the same properties  together,
which in turn is  dependent  upon  approval  of the  proposal  being made to the
Partnership and the similar proposal being made  simultaneously to the companion
Operating  Partnership.  Failure to approve the  proposal by either  partnership
could  significantly  adversely  affect  the  sale of  properties  by the  other
partnership.    See   "The   Proposal--Simultaneous    Proposal   to   Operating
Partnerships."

                                  THE PROPOSAL

General

      The Managing  General  Partner has  proposed  that the  Partnership's  net
profits  interest be sold,  the  Partnership  be dissolved and that the Managing
General  Partner,  acting as  liquidator,  wind up its  affairs  and make  final
distributions to its partners. The Partnership's assets consist of a net profits
interest (the "Property Interests") in producing oil and gas properties in which
the working  interest is owned by an affiliated  partnership also managed by the
Managing  General  Partner  and  formed  at  approximately  the same time as the
Partnership was organized. The Partnership's  non-operating net profits interest
exists by virtue of a Net  Profits and  Overriding  Royalty  Interest  Agreement
("NP/OR  Agreement")  dated December 31, 1990 Swift Energy Income Partners 1990-
D, Ltd. (the "Operating Partnership"). The NP/OR Agreement gives the Partnership
a net profits interest in a group of producing properties in which the Operating
Partnership owns the working interests,  and entitles the Partnership to receive
a portion of the net profits from operation of the group of producing properties
owned by the Operating Partnership which are subject to the NP/OR Agreement. The
net  profits  percentage  to which the  Partnership  is entitled is based upon a
percentage of the gross proceeds (reduced by certain costs) from the sale of oil
and gas production from these properties.

      The Managing  General  Partner  intends to sell most of the  Partnership's
Property  Interests  through  auction  conducted by the O&G  Clearinghouse  or a
similar company,  although some of the Partnership's Property Interests might be
sold to a third party in negotiated  transactions.  The Managing General Partner
expects to sell all properties not sold by auction  pursuant to negotiated sales
conducted by the Managing General Partner or a third party engaged to dispose of
the  Partnership's  assets.  The Partnership,  if not terminated  earlier,  will
terminate automatically,  pursuant to the terms of the Partnership Agreement, on
January 1, 2021.

      The Managing General Partner is an independent oil and gas company engaged
in the  exploration,  development,  acquisition  and  operation  of oil  and gas
properties,   both   directly  and  through   partnership   and  joint   venture
arrangements,  and  therefore  holds  various  interests in numerous oil and gas
properties.  Furthermore,  the Managing  General Partner is the managing general
partner of a number of oil and gas partnerships.

Partnership Financial Performance and Condition

      The Partnership owns non-operating Property Interests in producing oil and
gas  properties  within  the  continental   United  States  in  which  Operating
Partnerships  managed by the Managing General Partner own the working interests.
By the end of 1991 the  Partnership  had expended  all of its  original  capital
contributions  for the purchase of a Property  Interest in oil and gas producing
properties.  During  1996  approximately  78% of the  Partnership's  revenue was
attributable to natural gas production. The Operating Partnership has, from time
to time, performed workovers and recompletions of wells in which the Partnership
has Property Interests, using funds advanced



                                        9

<PAGE>



by the Managing General Partner to perform these operations,  a portion of which
amounts has been subsequently repaid from production.

      The  Limited  Partners  have  made  contributions  of  $2,930,379  in  the
aggregate  to the  Partnership.  The Managing  General  Partner has made capital
contributions  with  respect to its  general  partnership  interest  of $23,340.
Additionally,  pursuant to the  presentment  right set forth in Article XVIII of
the Partnership Agreement, it purchased 1,214 Units from Limited Partners.

      From inception  through  January 31, 1997, the  Partnership  has made cash
distributions to its Limited Partners totaling  $1,391,400.  Through January 31,
1997,  the Managing  General  Partner has received cash  distributions  from the
Partnership of $129,299 with respect to its general  partnership  interest,  and
distributions of $5,202 related to its limited partnership  interests.  On a per
Unit basis,  Limited Partners had received,  as of January 31, 1997,  $47.48 per
$100 Unit, or approximately 47.48% of their initial capital contributions.

      The Partnership acquired its Property Interests at a time when oil and gas
prices and industry  projections of future prices were much higher than actually
occurred  in  subsequent  years.  As  detailed  in  the  Designated   Properties
Supplement dated October 18, 1990 regarding Property Interests to be acquired by
the Partnership,  when the Managing General Partner projected future oil and gas
prices to evaluate the economic  viability  of an  acquisition,  it compared its
forecasts  with  those made by banks,  oil and gas  industry  sources,  the U.S.
government,  and other companies  acquiring  producing  properties.  Acquisition
decisions for the Partnership were based upon a range of increasing  prices that
were within the  mainstream of the forecasts made by these outside  parties.  At
the time that the Partnership's Property Interests covering producing properties
were acquired,  prices averaged about $22.88 per barrel of oil and $2.15 per Mcf
of natural gas. Oil and gas prices were expected to escalate  during  subsequent
years of the Partnership's  operations.  In general, in 1990 and early 1991, all
of these sources forecasted increases in product prices that were based upon oil
and gas prices at the time,  which  reflected  the invasion of Kuwait by Iraq in
the summer of 1990 and the  commencement of hostilities in the Gulf War in 1991.
The majority of the  Partnership's  Property  Interests were acquired during the
fourth  quarter of 1990 and the first  quarter of 1991 when current  prices were
predicted to escalate  according to certain parameters from that level. Thus the
majority of properties were bought upon an evaluated  weighted  average price of
$2.15 per Mcf.  The  predicted  price  increases  did not occur and prices  fell
precipitously  from late 1991 to 1992.  The bulk of the  Partnership's  reserves
were produced from 1991-1995 during which time the  Partnership's  oil prices in
fact averaged  $16.37 per barrel and natural gas prices  averaged  approximately
$1.75 per Mcf.

      The  following  graphs  illustrate  the above  factors with respect to gas
revenues only, due to the fact that a substantial  majority of the Partnership's
production to date being natural gas, the bulk of which was produced  during the
years when gas prices were the lowest.

         In addition to the effect of prices,  Partnership  performance has been
impacted by subsequent  enhancement  activities  which were  undertaken  shortly
after  partnership  formation on properties  in which the Operating  Partnership
held a working  interest.  Six successful  development wells were drilled in the
San Salvador Field,  Hidalgo County,  Texas, between December 1990 and July 1991
by a third party operator. In addition,  further development drilling activities
were undertaken on other  properties in which the Operating  Partnership  held a
working interest.



                                       11

<PAGE>



Between July, 1991 and the end of 1993 eleven development wells were drilled, of
which ten were  successful in Andrews,  Irion,  Schieicher,  and Webb  Counties,
Texas. The benefit of these enhancement activities,  however, was reduced by the
need to repay the costs incurred for these enhancements.

         Lower prices also had an effect on the Partnership's interest in proved
reserves.  Estimates  of proved  reserves  represent  quantities  of oil and gas
which,  upon analysis of engineering  and geologic data,  appear with reasonable
certainty  to be  recoverable  in the future  from known oil and gas  reservoirs
under  existing  economic and operating  conditions.  When economic or operating
conditions  change,  proved reserves can be revised either up or down. If prices
had  risen  as  predicted,  the  volumes  of  oil  and  gas  reserves  that  are
economically  recoverable  might  have  been  higher  than the  year-end  levels
actually reported because higher prices typically extend the life of reserves as
production  rates from mature wells  remain  economical  for a longer  period of
time. Production  enhancement projects that are not economically feasible at low
prices can also be implemented as prices rise. At present,  because of the small
remaining  amount  of  reserves,  further  price  increases  would  not  have  a
significant impact on the Partnership's performance.

         As required by the Partnership Agreement,  the Partnership expended all
of the partners' net commitments  available for property acquisitions many years
ago to acquire Property  Interests in producing oil and gas properties.  The net
profits paid by the Operating  Partnership to the Partnership  have been reduced
by amounts used by the Operating  Partnership  to pay operating and  enhancement
costs to the third party operator.  These costs relate to the working  interests
that were  subject to the  Partnership's  net  profits  interest.  The  Managing
General  Partner  of the  Operating  Partnership  advanced  most of these  costs
because  it  felt  that  such  expenditures  would  increase  the  value  of the
properties  in which  the  Partnership  and the  Operating  Partnership  have an
interest.  Neither the  Operating  Partnership's  partnership  agreement nor the
Partnership's  partnership  agreement  allow  additional  assessments to be made
against any Limited  Partners.  No material  funds are  available at the current
time from  Partnership  revenues or other sources to enable the  Partnership  to
make  additional  capital  expenditures  and no  new  capital  expenditures  are
planned.  The  Managing  General  Partner  anticipates  that  if  sales  of  the
Partnership's  properties occur,  there will be sufficient cash generated by the
sales of the Partnership's properties to make a final liquidating distribution.

Estimates of Liquidating Distribution Amount

         It is not  possible  to  accurately  predict  the  prices  at which the
Property  Interests  will be sold.  The  sales  price of the  Partnership's  net
profits  interest or possibly  multiple net profits  interests  may vary. In the
latter case, certain Property Interests might sell for a higher price and others
for a lower  price than those  estimated  below.  The  projected  range of sales
prices  below  has  been  based  upon  estimated  future  net  revenues  for the
Partnership's  Property  Interests,  using an  estimate of 1997  average  prices
without  any  escalation  of $2.25 per  Mmbtu.  The  future  net  revenues  from
production of such  properties have then been discounted to present value at 10%
per annum. The 1997 price estimate grew out of the pricing scenarios  determined
by the



                                       12

<PAGE>



Managing  General  Partner,  which scenarios are used in various  circumstances,
including economic modeling of partnership  returns and evaluating the economics
of property sales or property  acquisitions  for the Managing General Partner or
for  partnerships  managed  by  the  Managing  General  Partner.  These  pricing
assumptions  vary from those mandated by the Securities and Exchange  Commission
("SEC") for reserves  disclosures under applicable SEC rules,  which require use
of prices at year-end, although the discount rate and lack of escalation are the
same. If estimates of reserves and future net revenues had been  prepared  using
December 31, 1996 prices, as mandated by the SEC, reserves,  future net revenues
and the present  value  thereof  would be  significantly  higher.  The  Managing
General  Partner has determined  not to use these higher prices because  current
estimates of 1997 average prices more  accurately  reflect prices  purchasers of
properties  are willing to pay,  rather than higher  values which do not reflect
the decrease in prices since year-end 1996.  For example,  the weighted  average
price of gas  received by the  Partnership  for the first six months of 1997 was
$2.36 per Mcf as compared to $4.68 per Mcf at December 31,  1996.  For the lower
end of such projected  sales  proceeds,  the estimated  sales proceeds have been
further  reduced to 70% of those shown for the higher end of the range.  On July
1, the Managing General  Partner's  estimated  weighted average price of gas for
the remainder of 1997 was $2.58 per Mcf.

         Set  forth  in  the  table  below  are  estimated   proceeds  that  the
Partnership may realize from sales of the  Partnership's  properties,  estimated
expenses of the related dissolution and liquidation of the Partnership,  and the
estimated amount of net distributions available for Limited Partners as a result
of such sales.

         If, on the other  hand,  the  Partnership  were to retain its  Property
Interests and continue to produce those properties  until  depletion,  the table
below  estimates the return to Limited  Partners,  discounted to present  value,
based upon the same pricing and discount  assumptions  used above. The estimates
of the present value of future net  distributions  have been further  reduced by
continuing audit, tax return preparation and reserve engineering fees associated
with continued operations of the Partnership,  along with direct and general and

not take  into  account  any sale of a  portion  of the  Partnership's  Property
Interests  necessary  in order  to  generate  sufficient  cash  proceeds  to pay
general,  administrative and operating expenses, which would reduce the revenues
of the Partnership.

(1)      Includes  cash and net  receivables  and  payables of the  Partnership.
         Limited  Partners'  future  net  revenues  are  based  on  the  reserve
         estimates at December  31, 1996  assuming  unescalated  prices based on
         predictions of 1997 average  prices.  To a limited  extent,  future net
         revenues may be influenced by a material  change in the selling  prices
         of oil or gas. For further  discussion of this,  see "--Reasons for the
         Proposal."  The actual prices that will be received and the  associated
         costs   may  be  more  or  less   than   those   projected.   See  "The
         Partnership--Partnership Financial Condition and Performance."
(2)      Includes  Limited   Partners'  share  of  general  and   administrative

(3)      Based upon the Partnership's  reserves having a projected 20-year life,
         assuming flat pricing.  To a limited extent,  net  distributions may be
         influenced  by a material  change in the selling  prices of oil or gas.
         For further  discussion of this,  see "--Reasons for the Proposal." The
         actual  prices that will be received  and the  associated  costs may be
         more or less than those projected.
(4)      Does not reflect effect of intermittent  sales of Property Interests to
         pay  administrative  costs  once  the  properties  no  longer  generate
         sufficient  revenues to cover such costs.  The Managing General Partner
         estimates that Property



                                       14

<PAGE>



         Interests  ranging  from an  average  of 10% to 15% of the value of the
         Partnership's  properties would have to be sold each year to cover such
         costs.
(5)      Discounted at 10% per annum.

         Among  factors which can affect the ultimate  sales price  received for
Partnership Property Interests are the following:

         (1)      The  above  cases  presume  that  100%  of  the  Partnership's
                  Property Interests will be sold.
         (2)      In  certain  instances,  the  Partnership,  together  with the
                  Operating  Partnerships  which will be  offering  its  working
                  interest in the  properties  in which the  Partnership  owns a
                  Property  Interest,  will own a large  enough  interest in the
                  properties  to allow the purchaser to designate a new operator
                  of the properties,  which normally increases the amount that a
                  purchaser is willing to pay.
         (3)      Changes in the  market  for gas or oil may affect the  pricing
                  assumptions  used by purchasers in evaluating  property  value
                  and possible purchase prices.
         (4)      Different  evaluations  of the amount of money  required to be
                  spent to enhance or maintain production may have a significant
                  effect upon the ultimate purchase price.
         (5)      In certain  instances,  the Managing  General  Partner may set
                  minimum  bidding  prices  for  those  properties   offered  at
                  auction, which may not be met.
         (6)      The  Managing  General  Partner may choose to package  certain
                  less attractive  properties  together with other properties in
                  order to enhance the likelihood of their sale.  Such packaging
                  could  result  in  a  significant   discount  by   prospective
                  purchasers of the value of the  Partnership's  more productive
                  properties contained in such packages.

         The Partnership  Agreement  authorizes the Managing  General Partner to
sell the  Partnership  Property  Interests at a price that the Managing  General
Partner deems reasonable. The proceeds of all sales, to the extent available for
distribution,  are to be  distributed  to the Limited  Partners  and the General
Partners in  accordance  with  Article  XVI.E of the  Partnership  Agreement  as
follows.  After use of available  proceeds from  property  sales to reserves for
contingent or unforeseen liabilities of the Partnership,  the proceeds are to be
used to repay the capital  accounts of the Partners whose capital  accounts have
not yet been repaid.  The amounts finally  distributed will depend on the actual
sales prices received for the Partnership  assets,  results of operations  until
such sales and other contingencies and circumstances.

Comparison of Sale Versus Continuing Operations

         Based on the above tables, it is estimated that a Limited Partner could
expect to receive from $15.46 to $21.11 per $100 Unit upon immediate sale of the
Partnership  Property Interests.  In comparison,  it is estimated that a Limited
Partner could expect to receive  approximately $22.02 per $100 Unit,  discounted
to present  value  ($32.69  per $100 Unit in actual  dollars on an  undiscounted
basis) over the life of its Property  Interests,  approximately 20 years, if the
Partnership continued operations.




                                       15

<PAGE>



         Such  estimates  are  based on  December  31,  1996  reserve  estimates
assuming  unescalated pricing throughout the remaining life of the properties in
which the Partnership owns an interest.  The actual prices that will be received
and  the  associated  costs  may be  more  or less  than  those  projected.  See
"--Estimate of Liquidating Distribution Amount."

Reasons for the Proposal

         The Managing  General Partner  believes that it is in the best interest
of the  Partnership  and the Limited  Partners for the  Partnership  to sell its
properties  at this  time  and to  dissolve  the  Partnership  and  make a final
liquidating cash distribution to its partners for the reasons discussed below.

         Potential Liquidating Distribution. After the sale of the Partnership's
Property   Interests,   there  will  be  funds   available   for  a  liquidating
distribution.  The Managing General Partner believes that the ability to receive
the estimated  liquidating  distribution in one lump sum currently,  rather than
the estimated  distributions from continue operations over the remaining life of
the Partnership,  is one of the benefits of the proposal.  Current  estimates of
the high range of such liquidating distributions are slightly lower than the net
present value  discounted at 10% per annum, of the Limited  Partners'  estimated
distributions  to be received from continued  operations of the  Partnership for
the 20 years  currently  estimated as the  remaining  life of the  Partnership's
reserves.  As discussed below,  however, over such a long period of time, prices
of gas are expected to vary and the likelihood of receiving the estimated  price
over the life of the Partnership is subject to significant  uncertainty.  A vote
in favor of the proposal thus might have the effect of making  additional  funds
currently available to the Limited Partners.

         Small  Amount  of  Remaining  Assets in  Relation  to  Expenses.  As of
December 31, 1996,  approximately 72% of the Partnership's  ultimate recoverable
reserves had been produced, and the Limited Partners' share of the Partnership's
interest in remaining reserves,  before any reduction for costs, is estimated to
be less than 648,000 Mcfe. The  Partnership's  share of oil and gas reserves are
expected  to  continue  to  decline  as   remaining   reserves   are   produced.
Distributions  to partners in recent years have declined and are not expected to
increase appreciably. Declines in well production are based principally upon the
maturity of the wells,  not on market  factors.  Each  producing well requires a
certain  amount of overhead  costs,  as  operating  and other costs are incurred
regardless  of the level of  production.  Likewise,  general and  administrative
expenses such as  compliance  with the  securities  laws;  producing  reports to
partners and filing  partnership tax returns do not decline as revenues decline.
As a result of the  depletion of the  Partnership's  oil and gas  reserves,  the
Managing  General Partner believes the  Partnership's  asset base and future net
revenues no longer justify the  continuation  of operations.  Consequently,  the
Managing General Partner expects that the Partnership will have to start selling
a portion of its Property  Interests to pay the expense of future operations and
administration. By accelerating the liquidation of the Partnership, those future
administrative  costs can be avoided and the receipt of the remaining cash value
of the interests of the Limited Partners in the Partnership can be accelerated.




                                       16

<PAGE>



         Effect of Gas Prices on Value.  The Managing  General Partner  believes
that the key factor affecting the Partnership's  long-term  performance has been
the decrease in oil and gas prices that  occurred  subsequent to the purchase of
the Partnership's properties.  Additionally,  prices are expected to continue to
vary widely over the remaining life of the Partnership,  and such changes in gas
prices will affect future estimates of revenues from continued operations of the
Partnership.  Based on 1996 year-end reserve  calculations,  the Partnership had
only about 28% of its ultimate  recoverable  reserves,  before any reduction for
costs,  remaining  for  future  production.  Because  of this  small  amount  of
remaining  reserves,  even if oil and gas prices were to increase in the future,
such  increases  would be  unlikely to have a net  positive  impact on the total
return on investment to the partners in view of the expenses of the  Partnership
as described above.

         Potential  of the  Properties.  Recovery  in  amounts  great  enough to
significantly  impact  the  results  of the  Partnership's  operations  and  the
ultimate cash  distributions  can only occur with the investment of new capital.
As provided in the Partnership  Agreement,  the Partnership  expended all of the
partners' net commitments  for the acquisition of Property  Interests many years
ago,  and it no longer has capital to invest in  improvement  of the  properties
through secondary or tertiary recovery. No additional development activities are
contemplated  by the  Operating  Partnership  on the  properties  in  which  the
Partnership has a non-operating interest.

         Orderly Sale of Properties  Through  Approval of the Proposal.  The oil
and gas market is volatile,  making the sale of the properties at optimal prices
very time sensitive.  Therefore,  the Managing General Partner believes that the
Partnership  should  liquidate and have the  flexibility  to sell its properties
when such sales appear to be most advantageous to the Partnership.  The approval
of the Proposal as it is set forth will provide the Managing General Partner the
flexibility to sell the remaining  properties in an orderly  fashion to maximize
the potential return to the Limited Partners. The approval of the Proposal would
also allow the Managing  General Partner to begin the winding up and dissolution
of the  Partnership  following  the  final  sale of  Partnership  property.  The
approval of the  Proposal  will act as the  approval  of all future  asset sales
without  the  approval by the Limited  Partners  of the  specific  terms of such
future sales.

         Limited Partners' Tax Reporting. Limited Partners will continue to have
a partnership income tax reporting  obligation with respect to his Units as long
as the Partnership continues to exist. There is no trading market for the Units,
so Limited Partners generally are unable to dispose of their interests. See "The
Partnership - No Trading  Market." The approval of the Proposal would also allow
the  Managing  General  Partner to begin the winding up and  dissolution  of the
Partnership. Following the approval of the Proposal and the dissolution and sale
of the  properties,  the  Limited  Partners  will  realize  gain  or  loss  or a
combination  of both  under the  federal  income tax laws.  Thereafter,  Limited
Partners  will have no further tax  reporting  obligations  with  respect to the
Partnership. The dissolution of the Partnership will also allow Limited Partners
to take a capital loss  deduction for  syndication  costs incurred in connection
with formation of the Partnership. See "Federal Income Tax Consequences."

Simultaneous Proposal to Operating Partnership

         Simultaneously with this proposal to the Partnership's Limited Partners
to sell all of its Property  Interests,  a similar proposal is being made to the
limited partners of the companion  Operating  Partnership which owns the working
interest in the same  properties in which the  Partnership  owns a non-operating
interest.  If both Partnerships approve the proposal,  then the working interest
and non-operating interest will be sold simultaneously.

         If the  Partnership  approves the proposal but its companion  Operating
Partnership does not, then the Managing General Partner will attempt to sell the
Non-Operating Interest owned by the Partnership to a third party. If no economic
sale can be made to a third  party,  which may occur  due to the  difficulty  in
selling a net  profits  interest  in a  property  when  operating  and  spending
decisions are controlled by another  entity,  then the Managing  General Partner
will get a fair  market  appraisal  of the value of the  Partnership's  Property
Interests and will purchase the Partnership's non-operating interests itself for
the highest price for which the Property  Interests are appraised.  The Managing
General Partner intends to obtain any such fair market value appraisal from J.R.
Butler & Company.

         If the  Partnership  does not approve the  proposal  but its  companion
Operating  Partnership  approves the proposal to sell its  properties,  then the
Operating  Partnership  will be  forced  to sell its  working  interests  in its
properties  subject to the net profits  interest owned by the Partnership  which
burdens  the  Operating  Partnership's  properties.  Again  this may  affect the
saleability of the Operating Partnership's  properties due to the burden on cash
flow caused by the existence of the Partnership's net profits interest.  If this
burden  prevents an economic  sale to a third party,  then the Managing  General
Partner will again obtain a third party appraisal of the Operating Partnership's
properties and purchase those Property Interests itself.

         Therefore  the  likelihood  of  sale  of  the  Partnership's   Property
Interests will be  significantly  affected by the ability of the Partnership and
its companion  Operating  Partnership to sell their  ownership  interests in the
same properties at approximately  the same time, which in turn is dependent upon
approval of the proposal being made to the Partnership and the similar  proposal
being made  simultaneously to the companion  Operating  Partnership.  Failure to
approve the proposal by either partnership could significantly  adversely affect
the sale of properties by the other partnership to the NP/OR Agreement.

Steps to Implement the Proposal

         Following the approval of the Proposal,  the Managing  General  Partner
intends to take the following steps to implement it:

                  i.   Make available to the  appropriate  persons (that is, the
                       third party, if any, handling the negotiated sales and/or
                       the  auction  house  and   prospective   purchasers)  the
                       following types of data:

                       --"Liquidation") using the Partnership's cash on hand and
                       proceeds from the sale of Partnership properties;

                  iii. Conduct a final  accounting  and distribute any remaining
                       cash to the  partners of the  Partnership  in  accordance
                       with the Partnership Agreement;

                  iv.  Cause final  Partnership  tax returns to be prepared  and
                       filed with the Internal  Revenue  Service and appropriate
                       state taxing authorities;

                  v.   Distribute  to the  Limited  Partners  final Form K-1 tax
                       information; and

                  vi.  File a  Certificate  of  Cancellation  on  behalf  of the
                       Partnership  with the  Secretary of State of the State of
                       Texas.

         Auction. The Managing General Partner (or a third party seller) intends
to engage the O&G  Clearinghouse  or  another  similar  company to conduct  live
auctions for the sales working  interests of the Operating  Partnership  and the
non-operating  interests of the Partnership.  The O&G  Clearinghouse (as well as
other such auction companies) is in the business of conducting  auctions for oil
and gas properties.  The O&G  Clearinghouse  establishes a data room, which they
leave open for a period of time  (generally  three to four  weeks),  after which
they hold a live auction.  The O&G Clearinghouse  requires advance  registration
for all  bidders.  Bidders may  participate  by  invitation  only,  after having
qualified  as  knowledgeable  and  sophisticated  parties  routinely or actively
engaged in the oil and gas business. The O&G Clearinghouse publishes a brochure



                                       19

<PAGE>



regarding the properties.  The O&G  Clearinghouse  is  headquartered in Houston,
Texas. In auctions conducted by the O&G Clearinghouse,  properties are generally
grouped into small packages with a single field often comprising a property.

         Estimated  Selling  Costs.  The  expenses  associated  with the auction
process  (auctioneer's fee plus advertising fee) is expected to be approximately
7% of the sales  price  received.  This does not include  internal  costs of the
Managing  General  Partner  with  respect to the  sales,  nor fees owed to third
parties for services incident to the sale. For example,  if the Managing General
Partner  engaged a third  party to sell the  properties,  this  would  entail an
additional fee (although in such a case the Managing General Partner's  internal
costs  would be  lower).  This  also  does not  include  the  costs of the proxy
solicitation. See "General Information--Solicitation."

         Negotiated Sale. Although the Managing General Partner intends to offer
the Partnership's and the Operating Partnership's Property Interests at auction,
it is possible  that the Managing  General  Partner or a third party engaged for
the purpose of selling the  Partnership's  assets may approach other oil and gas
companies  and  negotiate a sale of certain  Property  Interests.  The  Managing
General  Partner  (or such  third  party)  may  solicit  bids on the oil and gas
properties  for which the  Managing  General  Partner  is the  operator.  If the
Managing  General  Partner (or third party)  solicits  bids, it will provide all
interested  parties with information  about the properties needed to bid on such
properties.  Such information would include raw data and historical  information
on all of the operated  properties that any of the  partnerships  managed by the
Managing  General  Partner  intends  to sell.  See  "--Steps  to  Implement  the
Proposal." The data will be organized by property.  Neither the Managing General
Partner  or any of its  affiliates  nor any of the  partnerships  managed by the
Managing General Partner will purchase any of the properties in this manner.  In
the  event of a bid that is lower  than a price  the  Managing  General  Partner
believes is  reasonable,  it may sell the  property to a third party  bidder for
such lower bid price, use another method of sale such as an auction, or have the
Partnership  continue to hold such property for a while longer.  If the property
has no appreciable  value,  which is likely to occur only if a Property Interest
has no  reserves  but  requires  expenditures  to plug and  abandon  wells,  the
Managing  General  Partner may dispose of such  property by  conveying it to the
operator  or  by  conveying  the  property  to  itself,  for  no  consideration.
Determination as to whether such conveyances will be made, including conveyances
to the  Managing  General  Partner  in such  cases,  will be made  solely by the
Managing General Partner.  In no event is the Managing General Partner obligated
to purchase any of the Property Interests.

         Other.  Any  sale  of  the  Partnership   Property  Interests  and  the
subsequent  liquidating  distributions to the Limited Partners, if any, pursuant
to the Proposal will be taxable  transactions under federal and state income tax
laws. See "Federal Income Tax Consequences."

Impact on the Managing General Partner

         The  Managing   General  Partner  will  be  economically   impacted  by
liquidation  in at least two ways.  First,  to the  extent of its  ownership  of
Units,  liquidation will have the same effect on it as on the Limited  Partners.
See "--Estimate of Liquidating Distribution Amount," and "--Estimated



                                       20

<PAGE>



Share of Limited Partners' Net Distributions from Continued Operations." Second,
because of the  dissolution and  liquidation of the  Partnership,  together with
liquidation of other  partnerships,  the Managing General Partner will no longer
hold the majority interest in various wells.  Different  operators are likely to
be selected and the Managing  General  Partner will therefore lose revenues that
it  currently  realizes  from its role as  operator  for those  properties.  The
Managing  General Partner is making its  recommendations  as set forth below, on
the basis of its  fiduciary  duty to the  Limited  Partners,  rather than on the
basis of the direct economic impact on the Managing General Partner.

Recommendation of the Managing General Partner

         For the foregoing  reasons,  the Managing General Partner believes that
it is in the best  interests of the Limited  Partners to dissolve and  liquidate
the  Partnership  in an  effort  to  maximize  the  value  of the  Partnership's
remaining  assets  and  the  amounts  distributed  to  Limited  Partners  and to
accelerate the receipt of such liquidating  distributions.  The Managing General
Partner  believes that through the  liquidation of the  Partnership's  remaining
assets in the near term,  Limited  Partners will benefit from the current higher
levels of oil and gas prices and  therefore,  may receive a greater  liquidating
cash distribution than if the Partnership were to continue to operate as a going
concern,  and be  subject to  possible  future  negative  changes in oil and gas
prices.  Additionally,  distribution  amounts may be affected by the anticipated
continuation of declines in revenues and the continuing relatively fixed general
and  administrative  and  operating  expenses  that  will  be  incurred  by  the
Partnership.  Continued operations of the Partnership would mean continuation of
the  additional  costs  incurred by the Limited  Partners,  including  the costs
associated  with inclusion of information  from the Schedule K-1 relating to the
Partnership in their personal income tax returns. Termination of the Partnership
will allow the current receipt of the remaining value of the Partnership and the
preparation of a final tax return,  and will make available  certain  additional
tax deductions.

         The Managing General Partner  recommends that the Limited Partners vote
FOR the Proposal.

                         FEDERAL INCOME TAX CONSEQUENCES

General

         The following summarizes certain federal income tax consequences to the
Limited Partners arising from the Partnership's proposed sale of its oil and gas
properties  and  liquidation  pursuant to the Proposal.  This  discussion is not
based upon an opinion of counsel and it is possible that different  results than
those  described  may  occur.  Statements  of legal  conclusions  regarding  tax
consequences are based upon relevant  provisions of the Internal Revenue Code of
1986, as amended (the "Code"),  and  accompanying  Treasury  Regulations,  as in
effect on the date hereof, upon private letter rulings dated October 6, 1987 and
August 22, 1991, upon reported judicial decisions and published positions of the
Internal Revenue Service (the "Service"),  and upon further assumptions that the
Partnership  constitutes  a  partnership  for federal tax  purposes and that the
Partnership  will be  liquidated  as described  herein.  The laws,  regulations,
administrative   rulings  and  judicial  decisions  which  form  the  basis  for
conclusions  with respect to the tax  consequences  described herein are complex
and are subject to prospective or retroactive  change at any time and any change
may adversely affect Limited Partners.

         This summary  does not  describe  all the tax aspects  which may affect
Limited  Partners  because  the tax  consequences  may vary  depending  upon the
individual  circumstances  of a Limited  Partner.  It is  generally  directed to
Limited  Partners that are qualified  plans and trusts under Code Section 401(a)
and individual retirement accounts ("IRAs") under Code Section 408 (collectively
"Tax Exempt  Plans") and that are the original  purchasers of the Units and hold
interests in the Partnership as "capital assets"  (generally,  property held for
investment).  Each Limited  Partner  that is not a  tax-exempt  Plan is strongly
encouraged to consult its own tax advisor as to the rules which are specifically
applicable  to it.  Except as  otherwise  specifically  set forth  herein,  this
summary  does not  address  foreign,  state or local  tax  consequences,  and is
inapplicable  to nonresident  aliens,  foreign  corporations,  debtors under the
jurisdiction  of a  court  in a  case  under  federal  bankruptcy  laws  or in a
receivership,  foreclosure  or similar  proceeding,  or an  investment  company,
financial institution or insurance company.

Tax Treatment of Tax Exempt Plans

         Sale of Property Interest and Liquidation of Partnership

         The Managing  General  Partner is  proposing to sell the  Partnership's
Property  Interest as well as any other  royalties and overriding  royalties the
Partnership may own. After the sale of the properties,  the Partnership's assets
will  consist  solely of cash,  which will be  distributed  to the  partners  in
complete liquidation of the partnership.

         Tax Exempt Plans are subject to tax on their unrelated business taxable
income ("UBTI"). UBTI is income derived by an organization from the conduct of a
trade or business  that is  substantially  unrelated to its  performance  of the
function that constitutes the basis of its tax exemption (aside from the need of
such organization for funds).  Royalty interests,  dividends,  interest and gain
from the



                                       22

<PAGE>



disposition  of capital  assets are generally  excluded from  classification  as
UBTI.  Notwithstanding these exclusions,  royalties,  interest,  dividends,  and
gains will create UBTI if they are  received  from  debt-financed  property,  as
discussed below.

         The   Internal   Revenue   Service  has   previously   ruled  that  the
Partnership's Property Interest, as structured under the NP/OR, is a royalty, as
are any  overriding  royalties the  Partnership  may own. To the extent that the
Property  Interest  is not  debt-financed  property,  neither  the  sale  of the
Property  Interest by the  Partnership nor the liquidation of the Partnership is
expected  to cause  Limited  Partners  that are Tax  Exempt  Plans to  recognize
taxable gain or loss for federal  income tax purposes,  even though there may be
gain or loss upon the sale of the  Property  Interest  for  federal  income  tax
purposes.

         Debt-Financed Property

         Debt-financed  property  is  property  held to produce  income  that is
subject  to  acquisition  indebtedness.  The  income  is  taxable  in  the  same
proportion  which the debt bears to the total cost of  acquiring  the  property.
Generally,  acquisition  indebtedness  is the unpaid amount of (i)  indebtedness
incurred  by a Tax Exempt Plan to acquire an  interest  in a  partnership,  (ii)
indebtedness  incurred in acquiring or improving property, or (iii) indebtedness
incurred  either before or after the  acquisition  or improvement of property or
the acquisition of a partnership  interest if such  indebtedness  would not have
been  incurred  but  for  such  acquisition  or  improvement,  and  if  incurred
subsequent  to  such   acquisition  or  improvement,   the  incurrence  of  such
indebtedness  was  reasonably  foreseeable  at the time of such  acquisition  or
improvement.  Generally, property acquired subject to a mortgage or similar lien
is  considered  debt-financed  property even if the  organization  acquiring the
property  does  not  assume  or  agree  to pay  the  debt.  Notwithstanding  the
foregoing,  acquisition  indebtedness  excludes certain indebtedness incurred by
Tax Exempt Plans other than IRAs to acquire or improve real  property.  Although
this  exception may apply,  its  usefulness  may be limited due to its technical
requirements  and the  fact  that  the  debt  excluded  from  classification  as
acquisition  indebtedness  appears to be debt incurred by a partnership  and not
debt  incurred by a partner  directly or  indirectly  in acquiring a partnership
interest.

         If a Limited  Partner that is a Tax Exempt Plan borrowed to acquire its
Partnership  Interest or had borrowed  funds either  before or after it acquired
its Partnership Interest,  its pro rata share of Partnership gain on the sale of
the Property  Interest may be UBTI. The Managing General Partner has represented
that  (i) the  Partnership  did not  borrowed  money  to  acquire  its  Property
Interest,  and (ii) that the Property Interest of the Partnership is not subject
to any debt,  mortgages  or  similar  liens  that will  cause the  Partnership's
Property Interest to be debt-financed  property under Code Section 514. If a Tax
Exempt  Plan  has  not  caused  its  Partnership  Interest  to be  debt-financed
property,  and based  upon the  representations  of the  Managing  General,  the
Property Interest is not expected to be considered debt-financed property.

Tax  Treatment  of  Limited  Partners  Subject  to  Federal  Income  Tax  Due to
Debt-financing or Who are Not Tax Exempt Plans




                                       23

<PAGE>



         All references hereinbelow to Limited Partners refers solely to Limited
Partners  that  either are not Tax Exempt  Plans or are Tax Exempt  Plans  whose
Partnership  Interest is  debt-financed.  To the extent that a Tax Exempt Plan's
Partnership Interest is only partially debt-financed,  the percentage of gain or
loss from the sale of the Property  Interest and  liquidation of the Partnership
that will be subject to  taxation  as UBTI is the  percentage  of the Tax Exempt
Plan's share of Partnership  income,  gain,  loss and deduction  adjusted by the
following  calculation.   Section  514(a)(1)  includes,  with  respect  to  each
debt-financed  property,  as gross income from an unrelated trade or business an
amount which is the same percentage of the total gross income derived during the
taxable year from or on account of the  property as (i) the average  acquisition
indebtedness  for the taxable  year with  respect to the property is of (ii) the
average  amount of the adjusted  basis of the  property  during the period it is
held by the organization during the taxable year (the "debt/basis percentage").

         A similar  calculation  is used to determine the allowable  deductions.
For  each  debt-financed   property,  the  amount  of  the  deductions  directly
attributable to the property are multiplied by the debt/basis percentage,  which
yields the allowable  deductions.  If the average  acquisition  indebtedness  is
equal to the average adjusted basis,  the debt/basis  percentage is zero and all
the income and deductions are included within UBTI. The debt/basis percentage is
calculated on an annual basis.

         Tax  Exempt  Plans  with  debt-financed  Partnership  Interests  should
consult  their tax advisors to determine the portion of gain or loss that may be
recognized for federal income tax purposes.  The following discussion of the tax
consequences  of  the  sale  of  the  Partnership   Property  Interest  and  the
liquidation of the Partnership  assumes that all of a Limited  Partner's income,
gain, loss and deduction from the Partnership is subject to federal taxation.

Taxable Gain or Loss Upon Sale of Properties

         A  Limited  Partner  will  realize  and  recognize  gain or loss,  or a
combination of both,  upon the  Partnership's  sale of its  properties  prior to
liquidation.  The amount of gain  realized  with  respect to each  property,  or
related asset,  will be an amount equal to the excess of the amount  realized by
the  Partnership   and  allocated  to  the  Limited   Partner  (i.e.,   cash  or
consideration  received) over the Limited Partner's  adjusted tax basis for such
property.  Conversely, the amount of loss realized with respect to each property
or related asset will be an amount equal to the excess of the Limited  Partner's
tax basis over the amount  realized by the  Partnership  for such  property  and
allocated  to the Limited  Partner.  It is  projected  that taxable loss will be
realized  upon the sale of  Partnership  properties  and that  such loss will be
allocated  among  the  Limited  Partners  in  accordance  with  the  Partnership
Agreement.  The  Partnership  Agreement  includes an allocation  provision  that
requires  allocations  pursuant  to a  liquidation  be made among  Partners in a
fashion that  equalizes  capital  accounts of the Partners so that the amount in
each  Partner's  capital  account will reflect such  Partner's  sharing ratio of
income and loss. The extent to which capital accounts can be equalized, however,
is limited by the amount of gain and loss available to be allocated.

         Realized gains and losses  generally must be recognized and reported in
the year the sale occurs.  Accordingly,  each  Limited  Partner will realize and
recognize his  allocable  share of gains and losses in his tax year within which
the Partnership properties are sold.



                                       24

<PAGE>



Liquidation of the Partnership

         After sale of its  properties,  the  Partnership's  assets will consist
solely of cash which it will distribute to its partners in complete liquidation.
The Partnership will not realize gain or loss upon such  distribution of cash to
its  partners in  liquidation.  If the amount of cash  distributed  to a Limited
Partner in liquidation is less than such Limited Partner's adjusted tax basis in
his  Partnership  interest,  the Limited  Partner will  realize and  recognize a
capital loss to the extent of the excess.  If the amount of cash  distributed is
greater  than such  Limited  Partner's  adjusted  tax  basis in his  Partnership
interest, the Limited Partner will recognize a capital gain to the extent of the
excess. Because each Limited Partner paid a portion of syndication and formation
costs upon  entering  the  Partnership,  neither of which costs were  deductible
expenses,  it is anticipated that liquidating  distributions to Limited Partners
will be less than such Limited  Partners' bases in their  Partnership  interests
and thus will generate capital losses.

Capital Gains Tax

         Net long-term capital gains of individuals,  trusts and estates will be
taxed at a maximum rate of 28%, while ordinarily  income,  including income from
the  recapture of depletion,  will be taxed at a maximum rate  depending on that
Limited  Partner's  taxable income of 36% or 39.6%.  With respect to net capital
losses,  other than Section 1231 net losses, the amount of net long-term capital
loss that can be utilized to offset  ordinary  income will be limited to the sum
of net capital gains from other sources recognized by the Limited Partner during
the tax year, plus $3,000 ($1,500,  in the case of a married individual filing a
separate  return).  The excess amount of such net long-term  capital loss may be
carried   forward  and  utilized  in  subsequent   years  subject  to  the  same
limitations.  Corporations  are taxed on net  long-term  capital  gains at their
ordinary Section 11 rates and are allowed to carry net capital losses back three
years and forward five years.

Passive Loss Limitations

         Limited Partners that are  individuals,  trusts,  estates,  or personal
service  corporations are subject to the passive activity loss limitations rules
that were enacted as part of the Tax Reform Act of 1986.

         A Limited Partner's allocable share of Partnership income,  gain, loss,
and  deduction  is  treated as derived  from a passive  activity,  except to the
extent of Partnership  portfolio  income,  which includes  interest,  dividends,
royalty income and gains from the sale of property held for investment purposes.
A Limited Partner's  allocable share of any gain or loss realized on sale of the
Partnership's  net profits interest is expected to be characterized as portfolio
and may not offset, or be offset by, passive activity gains or losses.

         THE FOREGOING  DISCUSSION IS INTENDED TO BE A SUMMARY OF CERTAIN INCOME
TAX  CONSIDERATIONS  OF THE SALE OF  PROPERTIES  AND  LIQUIDATION.  EACH LIMITED
PARTNER  SHOULD  CONSULT  ITS OWN TAX  ADVISOR  CONCERNING  ITS  PARTICULAR  TAX
CIRCUMSTANCES AND THE FEDERAL,  STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES
TO IT OF THE SALE OF PROPERTIES AND THE LIQUIDATION OF THE PARTNERSHIP.

                           BUSINESS OF THE PARTNERSHIP

         The  Partnership  is a Texas limited  partnership  formed  December 31,
1990.  Units  in the  Partnership  are  registered  under  Section  12(g) of the
Securities Exchange Act of 1934. In addition to the following  information about
the business of the Partnership, see the attached Annual Report on Form 10-K for
the year ended December 31, 1996, and its quarterly  report on Form 10-Q for the
second quarter of 1997, both included herewith.

Reserves

         For  information  about  the  Partnership's  interest  in oil  and  gas
reserves and future net revenue  expected from the  production of those reserves
as of December 31, 1996, see the attached report which was audited by H. J. Gruy
& Associates,  Inc., independent petroleum consultants.  It should be noted that
the  reserve  estimates  in the Annual  Report on Form 10-K  reflect  the entire
Partnership  reserves and that the reserve report in the attached letter from H.
J. Gruy &  Associates,  Inc.  reflects only the Limited  Partners'  share of the
Partnership's  estimated oil and gas reserves.  Neither of these reports reflect
the Partnership's share of future costs of operations which must be debited from
the  Partnership's  interest in reserves in order to determine the Partnership's
net interest in reserves by virtue of its net profits interest.  This report has
not been updated to include the effect of production  since  year-end  1996, nor
has the annual review of estimated quantities done each year-end taken place for
1997.

         There are numerous  uncertainties  inherent in estimating quantities of
proved  reserves and in  projecting  the future rates and timing of  production,
future costs and future development plans. Oil and gas reserve  engineering must
be recognized as a subjective process of estimating underground accumulations of
oil and gas that  cannot be  measured in an exact way,  and  estimates  of other
engineers  might differ from those in the attached  report.  The accuracy of any
reserve  estimate  is a  function  of  the  quality  of  available  data  and of
engineering  and geological  interpretation  and judgment.  Results of drilling,
testing  and  production  subsequent  to the date of the  estimate  may  justify
revision of such estimate,  and, as a general rule, reserve estimates based upon
volumetric  analysis are  inherently  less  reliable than those based on lengthy
production history. Accordingly,  reserve estimates are often different from the
quantities of oil and gas that are ultimately recovered.

         In  estimating  the  Partnership's  interest  in oil  and  natural  gas
reserves,  the  Managing  General  Partner,  has used flat  pricing  based  upon
estimates of 1997 average prices, without escalation,  except in those instances
where fixed and  determinable  gas price  escalations  are covered by contracts,
limited  to the price the  Partnership  reasonably  expects  to  receive.  These
pricing  assumptions  vary from those  mandated by the  Securities  and Exchange
Commission  ("SEC") for reserves  disclosures under applicable SEC rules,  which
require  use of prices  at  year-end,  although  the  discount  rate and lack of
escalation  are the same.  If  estimates of reserves and future net revenues had
been prepared using December 31, 1996 prices, as mandated by the SEC,  reserves,
future net revenues and the present value thereof would be significantly higher.
The Managing  General  Partner has  determined  not to use these  higher  prices
because current estimates



                                       26

<PAGE>



of 1997 average prices more accurately  reflect prices  purchasers of properties
are willing to pay,  rather than higher values which do not reflect the decrease
in prices since year-end 1996.  For example,  the weighted  average price of gas
received  by the  Partnership  during the first six months of 1997 was $2.36 per
Mcf, as compared to $4.68 per Mcf at December  31, 1996.  The  Managing  General
Partner  does  not  believe  that any  favorable  or  adverse  event  causing  a
significant change in the estimated quantity of proved reserves set forth in the
attached  report has occurred  between  December 31, 1996,  and the date of this
Proxy Statement.

         Future prices received for the sale of the  Partnership's  products may
be higher or lower than the prices used in the  Partnership's  estimates  of oil
and gas  reserves;  the operating  costs  relating to such  production  may also
increase or decrease from existing levels.

The Managing General Partner

         Subject to certain limitations set forth in the Partnership  Agreement,
the Managing General Partner has full,  exclusive and complete discretion in the
management and control of the business of the Partnership.  The Managing General
Partner has general liability for the debts and obligations of the Partnership.

         The Managing  General Partner is engaged in the business of oil and gas
exploration, development and production, and the Managing General Partner serves
as the  general  partner  of a number of other oil and gas  income  and  pension
partnerships.  The Managing General  Partner's common stock is traded on the New
York and Pacific Stock Exchanges.

         The principal  executive  offices of the Managing  General  Partner are
located at 16825 Northchase Drive,  Suite 400, Houston,  Texas 77060,  telephone
number (281) 874-2700.

Transactions Between the Managing General Partner and the Partnership

         Under the  Partnership  Agreement,  the  Managing  General  Partner has
received   certain   compensation  for  its  services  and   reimbursement   for
expenditures made on behalf of the Partnership, which was paid at closing of the
offering of Units, in addition to revenues distributable to the Managing General
Partner with respect to its general partnership  interest or limited partnership
interests it has  purchased.  In addition to those  revenues,  compensation  and
reimbursements,  the following  summarizes the transactions between the Managing
General  Partner  and the  Partnership  pursuant to which the  Managing  General
Partner has been paid or has had its expenses reimbursed on an ongoing basis:

         o        The Managing  General Partner has received  management fees of
                  $73,259, internal acquisition costs reimbursements of $143,297
                  and  formation  costs   reimbursements  of  $58,608  from  the
                  Partnership from inception through June 30, 1997.

         o        The  Managing  General  Partner   receives   per-well  monthly
                  operating  fees from the  Operating  Partnership  for  certain
                  producing wells in which the Partnership owns Property



                                       27

<PAGE>



                  Interests  and for which it serves as operator  in  accordance
                  with the joint  operating  agreements  for each of such wells.
                  The fees that are set in the joint  operating  agreements  are
                  negotiated  with the  other  working  interest  owners  of the
                  properties.

         o        The Managing  General Partner is entitled to be reimbursed and
                  has been reimbursed from inception to June 30, 1997,  $277,025
                  for general and administrative costs incurred on behalf of and
                  allocable to the Partnership,  including employee salaries and
                  office  overhead.  Amounts  are  calculated  on the  basis  of
                  Limited  Partner  capital  contributions  to  the  Partnership
                  relative to limited partner  contributions of all partnerships
                  for which the  Managing  General  Partner  serves as  Managing
                  General Partner.

         o        The Managing  General Partner has been reimbursed  $11,504 for
                  direct  expenses,  all of which was  billed  by, and then paid
                  directly to, third party vendors.

No Trading Market

         There is no  trading  market  for the Units,  and none is  expected  to
develop. Under the Partnership Agreement, the Limited Partners have the right to
present their Units to the Managing  General  Partner for  repurchase at a price
determined in accordance  with the formula  established  by Article XVIII of the
Partnership  Agreement.   Originally,  279  Limited  Partners  invested  in  the
Partnership.  Through  December  31,  1996,  the  Managing  General  Partner had
purchased  1,214  Units  from  Limited   Partners   pursuant  to  the  right  of
presentment.  As of August 15, 1997, there were 277 Limited Partners  (excluding
the Managing  General  Partner).  The Managing  General Partner does not have an
obligation to repurchase  Limited  Partner  interests  pursuant to this right of
presentment  but merely an option to do so when such interests are presented for
repurchase.

Principal Holders of Limited Partner Units

         The  Managing   General  Partner  holds  4.14%  of  the  Units  of  the
Partnership.  To the  knowledge of the  Managing  General  Partner,  there is no
holder of Units that holds more than 5% of the Units.

Approvals

         No  federal  or state  regulatory  requirements  must be  satisfied  or
approvals  obtained in connection  with the sale of the  Partnership's  Property
Interests.

Legal Proceedings

         The Managing General Partner is not aware of any material pending legal
proceedings to which the  Partnership is a party or of which any of its property
is the subject.
