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.
It is important  that you review the  enclosed  materials  before  voting on the
proposal. The Managing General Partner recommends that you vote in favor of such
sale and liquidation for a number of reasons. See "The Proposal--Reasons for the
Proposal" and "--Recommendation of the Managing General Partner."

     Swift Energy Managed Pension Assets  Partnership  1990-D,  Ltd. has been in
existence for almost seven years, and most of the properties  underlying its net
profits  interest were  purchased by early 1991. No capital is available for any
enhancement   activities  on  the  properties  in  which  the  Partnership  owns
non-operating interests or to produce the proved non-producing reserves on those
properties.  The Partnership's  interest in proved producing reserves at January
1, 1997 is only 506,000 Mcfe.  Thus,  even if oil and gas prices were  unusually
high,  there would be little  impact upon the  Partnership's  ultimate  economic
performance.   See  "The   Proposal--Partnership   Financial   Performance   and
Condition."  To continue  operation of the  Partnership  means that  Partnership
direct and  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  continue to decrease,  which may decrease the ultimate
funds  available  for  Limited  Partners.   See  "The   Proposal--Estimates   of
Liquidating  Distribution  Amount."  Liquidation of the Partnership's  remaining
assets at this time 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 the first quarter of 1998.

     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.

                           To be held October 30, 1997


     Notice is hereby given that a special meeting of limited  partners of Swift
Energy Managed Pension Assets Partnership  1990-D, Ltd. (the "Partnership") will
be held at 16825 Northchase Drive, Houston, Texas, on Tuesday,  October 30, 1997
at 4:00 p.m. Central Time to consider and vote upon:

      The adoption of a proposal for (a) sale of substantially all of the assets
      of the Partnership  (consisting of its net profits interest),  and (b) the
      dissolution,   winding  up  and  termination  of  the   Partnership   (the

that date will be  entitled  to  notice  of and to vote at the  meeting,  or any
adjournment thereof.

     If you do not expect to be  present  in person at the  meeting or prefer to
vote by proxy in advance,  please sign and date the enclosed proxy and return it
promptly in the enclosed  postage-paid envelope which has been provided for your

                                 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,
October  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 October 6, 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 September 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 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.


                                      
                                        1

<PAGE>



     Neither  the  Managing  General  Partner  nor  any of its  affiliates  will
purchase any of the Partnership's Property Interests at auction or in negotiated
transactions, although it is possible that if a Property Interest cannot be sold
to a third  party at auction or on a  negotiated  basis  (which  usually  occurs
because a property has no appreciable  value, often accompanied by the fact that
the property  requires  expenditures  to plug and abandon  wells) such  Property
Interests  may be conveyed to the  Managing  General  Partner or the  property's
operator for no  consideration  if necessary  to dispose of such  interest.  The
Managing General Partner is not currently aware of any Property  Interests owned
by the  Partnership  which are likely to be conveyed in this  manner.  The total
PV-10 Value of the Partnership's  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.  All  sales  of the  Partnership's
Property  Interests  will  be  made  through  the  auction  process  or  through
negotiated  transactions to  unaffiliated  third parties.  The Managing  General
Partner  anticipates that most of the Partnership's  Property  Interests will be
sold at auction  (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 the first quarter of 1998. 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."

                         PARTNERSHIP PROPERTY INTERESTS

     The  chart  below  presents  information  on  those  fields  in  which  the
Partnership  has a  Property  Interest  which  constitutes  10% or  more  of the
Partnership's PV-10 Value at January 1, 1997. The information below includes the
location  of each  field,  the number of wells and  operator(s),  together  with
information on the percentage of the Partnership's  total PV-10 Value ($560,688)
on January 1, 1997  attributable  to each of these fields.  Information  is also
provided  regarding  the  percentage  of the  Partnership's  production  for the

<PAGE>



eighteen  months  ended June 30, 1997 on a  volumetric  basis from each of these
fields.  On a volumetric  basis, the percentage of the PV-10 Value at January 1,
1997 of these fields  attributable to natural gas ranged between 87.8% and 99.6%
and most of the  production  from  these  fields (in excess of 75% in every case
during the past eighteen months) has been natural gas.

     Of the  remaining  nine  fields in which the  Partnership  owns a  Property
Interest,  three fields each  comprise less than 1% of the  Partnership's  PV-10
Value at  January  1, 1997 and the PV-10  Value of each of the other six  fields
average 4.2% of the Partnership's PV-10 Value at the same date.

                             SPECIAL CONSIDERATIONS

Reasons for the Proposal

     Sale of the  Partnership's  assets and  liquidation of the  Partnership are
being proposed for Limited Partner approval in an attempt to realize the highest
value for the Partnership's  Property  Interests.  The reasons for proposing the
sale of the  Partnership's  Property  Interests  at this time are  described  in
detail  under "The  Proposal -- Reasons  for the  Proposal."  In summary,  these
reasons  include:  (i) the  reduced  levels of cash flow from the  Partnership's
Property Interests, which has resulted in cash distributions to Limited Partners
since January 1, 1996 of only $62,300; (ii) the inherent decline in hydrocarbons
produced by oil and gas wells over time in the  absence of any  further  capital
expenditures on the properties in which the Partnership has a Property Interest;
(iii) the  continuation  of certain fixed oil field overhead and operating costs
($27,665 in 1996) which are incurred regardless of the level of production;  and
(iv) directs costs (audits,  reserve reports,  partnership  filings) and general
and  administrative  costs incurred each year ($52,307 in 1996).  Because of the
depletion of the  Partnership's oil and gas reserves (647,978 Mcfe at January 1,
1997) and current low levels of cash flow, the Managing General Partner believes
that the Partnership's  asset base and future net revenues no longer justify the
continuation of the  Partnership's  operations.  It is also the Managing General
Partner's belief that  improvements  over the last several years in the level of
oil and gas prices, particularly those for natural gas, make this an appropriate
time to consider the sale of the Partnership's Property Interests,  and increase
the likelihood of maximizing the value of the Partnership's assets, although the
level of future  prices cannot be  predicted with any  accuracy.  By selling its

                                        3

<PAGE>



Property Interests and liquidating the Partnerships, future overhead, direct and
general  administrative costs can be avoided and the receipt of the value of the
Partnership's  reserves accelerated so that such funds are received at one time.
Such  sale  and  liquidation  is  viewed  by the  Managing  General  Partner  as
preferable to requiring the periodic sale of a portion of its Property Interests
over a long  period  of  time to pay  the  expenses  of  future  operations  and
administration.

Fairness of the Proposal

     The  Managing  General  Partner  believes  that  the  Proposal  to sell the
Partnership's  Property  Interests and liquidate is fair to Limited Partners for
several  reasons.  No such  transactions  will take place unless the Proposal is
approved by a majority of Limited Partners, without the Managing General Partner
voting  its 4.14%  limited  partnership  interest.  The  Partnership's  Property
Interests  will be sold to the highest  third-party  bidder at auction or to the
third party which is willing to purchase the  interests for the highest price in
a negotiated sale.

     Although  the  estimates  contained  under  "The   Proposal--Estimates   of
Liquidating Distribution Amount" above show that estimated cash distributions to
Limited  Partners  (based on net present value) from continued  operations  over
twenty  years  would  be   approximately   4.3%  higher  than   estimated   cash
distributions  from selling the  Partnership's  properties and  liquidating  the
Partnership at this time (based on the "high" range of estimates),  the Managing
General  Partner  believes  there is a  substantial  advantage in receiving  the
liquidating   distribution   in  one  lump  sum  currently.   The  estimates  of
distributions  from continued  operations are based upon current  prices.  It is
highly likely that over such a long period of time, oil and gas prices will vary
appreciably and possibly widely from the prices used to prepare these estimates.
Continued operations over such a long period of time subject Limited Partners to
the risk of receiving lower levels of cash  distributions  if oil and gas prices
over this twenty year period are lower on average  than those used in  preparing
the estimates of cash distributions from continued  operations.  With no further
capital to invest,  continued  operations  over  twenty  years  subject  Limited
Partners  to the risks of  possible  changes  in costs or need for  workover  or
similar or significant  remedial work on the properties in which the Partnership
owns Property Interests,  for which the Partnership has no capital. The Managing
General  Partner also  believes  that there is an advantage to Limited  Partners
taking any funds to be received upon liquidation and redeploying those assets in
other  investments,  rather than continuing to receive small  distributions over
such a long period of time.

            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,  although a final  liquidating  distribution is
     anticipated,    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.

       LIMITED PARTNERS ARE URGED TO COMPLETE, SIGN AND DATE THE ENCLOSED
         PROXY AND TO RETURN IT TO THE MANAGING GENERAL PARTNER NO LATER
                             THAN OCTOBER 24, 1997.

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

                                        6

<PAGE>



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


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 Statement,  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

     A sample of the form of proxy is  included  in this  Proxy  Statement.  The
actual  proxy to be used to register  your vote on the  Proposal is the separate
green sheet of paper  included  with the Proxy  Statement.  PLEASE USE THE GREEN
PROXY TO VOTE UPON THE PROPOSAL.

     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.

No Appraisal or Dissenters' Rights Provided

     In connection with the proposal to sell substantially all of its assets and
liquidate the Partnership,  Limited Partners are not entitled to any dissenters'
or appraisal  rights such as would be available to shareholders in a corporation
engaging in a merger.  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

                                        8

<PAGE>



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.

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.  If this lack of control prevents an economic sale to a third party
of the Partnership's Property Interests,  then the Managing General Partner will
again obtain a third party  appraisal of the  Partnership's  Property  Interests
from J.R. Butler and purchase those  properties  itself for the appraised price.
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

                                        9

<PAGE>



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."

Prices Used for Calculation of PV-10 Value of Proved Reserves

     The PV-10 Value of the Partnership's proved oil and gas reserves upon which
the estimates of the range of  liquidating  distributions  have been  calculated
using an estimate of 1997 average  prices  without any  escalation  of $2.25 per
MMBTU.  These  estimates  were based upon pricing  scenarios  determined  by the
Managing  General  Partner  and are  not  the  same  as  those  mandated  by the
Securities and Exchange Commission 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. These higher prices have not been used because of the fall
in prices since year-end 1996 and the Managing General  Partner's  determination
that reserve estimates using 1997 average prices more accurately  reflect values
likely to be received upon sale of the Partnership's  Property  Interests within
the next six months than  estimates  based upon  year-end  1996 prices.  If this
assumption  is  incorrect  or prices  increase  rapidly at the end of 1997,  the
estimates  of  the  Partnership's  PV-10  Value  and  proceeds  receivable  upon
liquidation of its Property Interests are likely to be too low.

                                  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  or to the  Managing  General
Partner  or its  affiliates  under  certain  circumstances  discussed  in detail
herein.  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 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.


                                       11

     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 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.

     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 "high" range of estimated  distributions from
liquidation  is based upon estimated  future net revenues  discounted to present
value at 10% per annum. The "low" range is 70% of the "high" range estimate. The
1997 price estimate grew out of the pricing scenarios determined by the 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.  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
administrative  expenses  estimated to occur during this time. Such estimates do
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  expenses,
     and audit, tax, and reserve engineering fees.

(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  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.
                                       15

<PAGE>



     (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.

Fairness of the Proposal; 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 over 20 years on an  undiscounted  basis)
over  the  life  of  its  Property  Interests,   if  the  Partnership  continued
operations.

     Although  the  estimates  contained  under  "The   Proposal--Estimates   of
Liquidating Distribution Amount" above show that estimated cash distributions to
Limited  Partners  (based on net present value) from continued  operations  over
twenty  years  would  be   approximately   4.3%  higher  than   estimated   cash
distributions  from selling the  Partnership's  properties and  liquidating  the
Partnership at this time (based on the "high" range of estimates),  the Managing
General  Partner  believes  there is a  substantial  advantage in receiving  the
liquidating   distribution   in  one  lump  sum  currently.   The  estimates  of
distributions  from continued  operations are based upon current  prices.  It is
highly likely that over such a long period of time, oil and gas prices will vary
appreciably and possibly widely from the prices used to prepare these estimates.
Continued operations over such a long period of time subject Limited Partners to
the risk of receiving lower levels of cash  distributions  if oil and gas prices
over this twenty year period are lower on average  than those used in  preparing
the estimates of cash distributions from continued  operations.  With no further
capital to invest,  continued  operations  over  twenty  years  subject  Limited
Partners  to the risks of  possible  changes  in costs or need for  workover  or
similar  significant  remedial work on the  properties in which the  Partnership
owns Property Interests,  for which the Partnership has no capital. The Managing
General  Partner also  believes  that there is an advantage to Limited  Partners
taking any funds to be received upon liquidation and redeploying those assets in
other  investments,  rather than continuing to receive small  distributions over
such a long period of time.

                                       16

<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. As discussed above, the Managing General Partner believes that the
ability  to  receive  the  estimated  liquidating  distribution  in one lump sum
currently,  rather than in smaller amounts over a 20 year period,  is one of the
benefits  of the  Proposal,  without  the  continuing  risk  of  such  potential
distributions being negatively  affected by oil and gas price decreases.  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,  direct  costs  and/or  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.

     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

                                       17

<PAGE>



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.  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 the Partnership's  Property Interests.  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 third  party  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 and 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

                                       18

<PAGE>



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:



          o    Engineering and Geological Data 
               - Production curve 
               - Completion report 
               - Historical production data 
               - Engineering well files 
               - Geological maps (if available) 
               - Logs (if available)

          o    Land/Legal Data  
               - Net Profits Interest schedule for all properties 
               - Land files 
               - Payout data

          o    Accounting Data  
               - Lease operating statements by well 
               - Gas marketing data 
               - Oil marketing data 
               - Gas balancing data

     ii.  Pay or  provide  for  payment  of the  Partnership's  liabilities  and
          obligations   to   creditors   (See  --   "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.

                                       19

     Auction.   The  Managing   General   Partner  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  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 nor its affiliates nor any of the  partnerships  managed by the Managing
General  Partner will purchase any of the  Partnership's  Property  Interests 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 a  property  cannot  be sold to a third  party  at  auction  or on a
negotiated  basis,  which usually occurs  because it has no  appreciable  value,
often  accompanied by the fact that the property  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. The Managing General Partner is not
currently aware of any Property  Interests  owned by the  Partnership  which are
likely  to be  conveyed  in this  manner.  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  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  will  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   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

                                       22

<PAGE>



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

     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.


                                       23

<PAGE>



     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.

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

                                       24

<PAGE>



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 and
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 and 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
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.


                                       26

<PAGE>



     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

     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,  which are less than 1.0%
of the Managing  General  Partner's net revenues.  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."

     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  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.


                                       27

<PAGE>



     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 September 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.
