[SWIFT LOGO]

Dear Investor:

   
     As your Managing General Partner, Swift Energy Company believes that the
time has come to dissolve and liquidate your Partnership.  Enclosed is a Joint
Proxy Statement/Prospectus and related information pertaining to a proposal for
the sale of all of your Partnership's oil and gas assets to the Managing
General Partner and the dissolution and liquidation of the Partnership.  The
price proposed to be paid by the Managing General Partner is based on the
higher of two fair market value estimates on a Partnership-by-Partnership basis
prepared by independent appraisers, plus a premium of 7.5% above such higher
fair market value estimate added by the Managing General Partner.  In order for
the sale and liquidation to take place; investors in your Partnership holding
at least a majority of the outstanding Units must approve this proposal.  IT IS
IMPORTANT THAT YOU REVIEW THE ENCLOSED MATERIALS BEFORE VOTING ON THE PROPOSAL,
WHICH YOU MAY VOTE "FOR" OR "AGAINST."

       The Managing General Partner recommends that you vote "FOR" such
proposed sale and liquidation for a number of reasons.  The Partnership has
been in existence for at least the planned five to ten years.  Limited capital
is available for enhancement or development activities on the properties in
which the Partnership owns interests.  To continue operation of the Partnership
means the direct and administrative expenses, as well as the cost of operating
the properties in which the Partnership owns an interest, will continue while
revenues decrease, which may decrease funds ultimately available to investors
in your Partnership.  See "Special Factors--Reasons for Proposals--Decreasing 
Cash Flow While Expenses Continue."  Thus, approval of the current sale of the
Partnership's property interests at this time will accelerate the receipt by
investors of the remaining cash value of the Partnership's property interests
while avoiding the risk of continued and extreme volatility of oil and gas
prices, as well as inherent geological, engineering and operational risks.  The
Managing General Partner believes that improvements over the last several years
in the level of natural gas prices, relative to such prices in the mid-1990's,
make this an appropriate time for the Investors to consider the sale of the
Partnership's property interests, which also increases the likelihood of
maximizing the value of such assets.  See "Special Factors--Reasons for the
Proposals" and "The Proposals--Recommendation of the Managing General Partner."

     Also included in this package are the most recent financial and other
information prepared regarding your Partnership.  The enclosed Joint Proxy
Statement/Prospectus relates to the proposal as well as presents an opportunity
for you to purchase shares of Swift Energy Company common stock directly from
Swift, without any broker commissions, with funds you may receive from any cash
distribution from your Partnership if the proposal is approved.  The shares are
offered to you should you wish to continue your investment in, among other
things, the Partnership's properties.  Of course, any such investment on your
part is your choice.  IF THE PROPOSAL IS APPROVED BY THE REQUISITE VOTE OF THE
INVESTORS IN THE PARTNERSHIPS, UNLESS YOU MAKE AN ELECTION TO RECEIVE SWIFT
ENERGY COMPANY SHARES, YOU WILL RECEIVE CASH UPON LIQUIDATION OF THE
PARTNERSHIP.  If you need any further material or have questions regarding this
proposal or the offering, 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 AND IS NECESSARY TO HAVE AN EFFECTIVE VOTE ON
THIS PROPOSAL.  Enclosed is a green Proxy, along with a postage-paid envelope
addressed to the Managing General Partner for your use in voting and returning
your Proxy.  Thank you very much.

                                          SWIFT ENERGY COMPANY,
                                          Managing General Partner

Information contained herein is subject to completion or amendment.  These

                              SWIFT ENERGY COMPANY

                        JOINT PROXY STATEMENT/PROSPECTUS
                        DATED ___________________, 1998

      Swift Energy Company, a Texas corporation ("Swift," the "Company" or
"Managing General Partner"), hereby submits for approval its proposals to
purchase all of the oil and gas assets (the "Property Interests") owned by 63
Texas limited partnerships (individually, a "Partnership" and, collectively,
the "Partnerships") for which it serves as Managing General Partner, and
thereafter, dissolve the Partnerships (for each Partnership, the "Proposal"
and, collectively, the "Proposals").  The net purchase price for the Property
Interests is expected to be approximately $70.6 million, subject to certain
reductions based on cash flow distributions to the Partnerships prior to
closing.  A portion of the purchase price for the Property Interests may be
funded by the concurrent offer hereby of up to 2,500,000 shares of common
stock, $.01 par value (the "Common Stock"), of the Company to certain Investors
(as defined) in the Partnerships who elect to receive Common Stock in lieu of
some or all of the cash that they will be entitled to receive upon their
Partnership's liquidation.

     Both the vote upon the Proposals and any election made by an individual
Investor to elect to receive shares of Common Stock are subject to numerous
risk factors, including these highlighted below:
    

o      Substantial conflicts of interest exist because if the Proposals are
       approved, the Managing General Partner will purchase assets from the
       Partnerships while it serves as Managing General Partner for the
       Partnerships.

   
o      Although the purchase price for Property Interests is based on
       appraisals by independent appraisers, it may or may not be the highest
       possible price.

o      No independent representative on behalf of the Investors negotiated the
       terms of the Proposal with the Managing General Partner.

o      No fairness opinion was obtained regarding the fairness of the Proposals
       or of the purchase price for any of the Partnerships.

o      Investors may forgo profit from approving the sale of the Property
       Interests that the Managing General Partner may gain by investing
       capital to recover behind-pipe reserves or develop non-developed
       reserves of those acquired assets, and possibly due to commodity price
       improvement.
    

o      An election by an Investor to receive shares of Common Stock in lieu of
       a cash distribution subjects such Investor to various risks of owning
       Common Stock.

o      An investment in the Company fundamentally differs from investments in
       the Partnerships.

RISK FACTORS THAT SHOULD BE CONSIDERED BY INVESTORS IN DETERMINING WHETHER TO
VOTE TO APPROVE THE PROPOSALS AND WHETHER TO ELECT TO PURCHASE ANY COMMON STOCK
IF THE PROPOSAL IS APPROVED BY THEIR PARTNERSHIP.

                         SPECIAL MEETINGS OF INVESTORS
                              OF THE PARTNERSHIPS

         This Joint Proxy Statement/Prospectus is being furnished to limited
partners or interest holders in the Partnerships (individually, an "Investor"
and collectively, the "Investors") in connection with the solicitation of
proxies (individually, a "Proxy" and collectively, the "Proxies") by the
Managing General Partner for use at Special Meetings of the Investors (the
"Special Meetings," or singly for each Partnership, the "Special Meeting") of
each of the Partnerships.  The Special Meetings are being called by the
Managing General Partner for Investors to consider and vote upon the Proposals
for the ultimate sale of substantially all of the Property Interests of each of
the Partnerships to the Company and the subsequent termination of such
Partnerships, and to transact such other business as may be properly presented
at the Special Meeting or any adjournments or postponements thereof.  In the
event of such sale of the Property Interests, the Partnerships' assets will
consist solely of cash which each Investor of the Partnerships will be entitled
to receive as a distribution pursuant to the terms of the limited partnership
agreement of each Partnership.

         The Company intends to profit through a return on the capital used to
purchase the Property Interests and by investing additional capital in their
further development.  The purpose of the Proposals is to wind up the business
of the Partnerships because the hydrocarbon production of the producing
properties in which the Partnerships own interests has steadily declined, as
was contemplated when the Partnerships were formed.  Furthermore, the
Partnerships do not have the capital to further develop their Property
Interests, nor was it contemplated at formation of the Partnerships that
additional capital contributions would be made by Investors. The Company in its
capacity as Managing General Partner believes that the Proposals are fair to
Investors and are structured in a manner that attempts to realize the highest
sales price for the Partnerships' Property Interests.  However, there can be no
assurance that the proposed purchase prices represent the highest possible
prices which could be received for the Property Interests.

                                  OFFERING OF
                        2,500,000 SHARES OF COMMON STOCK
                            OF SWIFT ENERGY COMPANY

         This Joint Proxy Statement/Prospectus also relates to the concurrent
offering (the "Offering") of up to 2,500,000 shares of Common Stock of the
Company being made solely to those Investors in Partnerships which along with
their Companion Partnerships (as defined) approve the Proposals (individually,
an "Eligible Purchaser" and collectively, the "Eligible Purchasers").  The
Company hereby offers to each Eligible Purchaser the opportunity to purchase
shares of Common Stock direct from the Company without any broker commissions.
The decision to purchase any shares of Common Stock rests with each Eligible
Purchaser and is completely voluntary.  The Common Stock may be purchased with
all or any portion of the Partnership cash distribution such Eligible Purchaser
will be entitled to receive, provided that a minimum round lot of 100 shares
must be purchased, although Eligible Purchasers may purchase shares in addition
to the number of shares purchasable with their liquidating distributions.
Eligible Purchasers may purchase shares of Common Stock with funds in addition
to their cash distributions in order to purchase the minimum round lot of 100
shares, subject to prorata limitations in the event of oversubscription.
Investors in multiple Partnerships may aggregate their cash distributions to
purchase the minimum round lot. The Common Stock is listed on the New York
Stock Exchange (the "NYSE") and the Pacific Exchange, Inc. (the "Pacific
Exchange") under the symbol "SFY."  The price at which the Common Stock offered
hereby will be issued will be the average price of the Common Stock as reported
by the NYSE for the period between ____________ and _____________, 1998.  The
closing price on the NYSE for the Common Stock on ________________, 1998, was
$______ per share.

PROPOSALS TO SELL EACH PARTNERSHIP'S OIL AND GAS ASSETS

   
         The Company is the Managing General Partner of 63 limited partnerships
formed between 1986 and 1994 to invest in producing oil and gas properties.
Swift is submitting this Joint Proxy Statement/Prospectus to Investors in each
of the 63 individual Partnerships to ask their approval of a Proposal to sell
all of that particular Partnership's oil and gas assets to the Managing General
Partner at a price set by taking the higher of two fair market value estimates
of those assets on a Partnership-by-Partnerships basis determined by three
independent appraisers, H.J. Gruy & Associates, J.R. Butler & Company and CIBC
Oppenheimer Corp. (collectively, the "Appraisers") and adding to that higher
number a 7.5% premium.  The total purchase price for all of the oil and gas
assets of all 63 partnerships is approximately $81 million as of December 31,
1997.
    

See "Special Factors--Background" and "Special Factors--Background and Purpose
of the Proposal" in each Partnership's Specific Partnership Supplement.

LIQUIDATION OF PARTNERSHIPS APPROVING THEIR PROPOSAL

   
         Each Partnership is voting separately on a Proposal.  Accordingly, not
all of the 63 Partnerships may choose to sell their oil and gas assets and
dissolve.  Investors in each of the 63 Partnerships may vote "FOR" or "AGAINST"
the Proposal being voted upon by their individual Partnership.  If the Proposal
is approved by Investors in a Partnership and, if applicable, by its Companion
Partnership, after the sale of substantially all of their properties such
Partnerships, will wind up their businesses and terminate.  The Partnerships
will receive cash for their oil and gas assets, which the Investors in the
Partnerships will be entitled to receive as distributions in accordance with
their respective percentage ownership interests in their Partnership.  If the
Proposal is rejected by the Investors of a particular Partnership or if a
Companion Partnership does not approve the Proposal, the Partnership will
continue to operate.
    

See "Special Factors--Purpose and Effect of the Proposals" and "The
Proposals--Simultaneous Proposal to Companion Partnerships" herein.

ELECTION TO PURCHASE COMMON STOCK

   
         Eligible Purchasers can elect, in their sole individual discretion, to
receive shares of Common Stock of the Company instead of some or all of the
cash which they are entitled to receive upon their Partnership's liquidation.
The shares will be sold directly by the Company without any broker commissions.
The minimum number of shares of Common Stock which must be purchased by an
Eligible Purchaser is a round lot of 100 shares.  If an Eligible Purchaser has
interests in more than one Partnership, the cash distributions he will be
entitled to receive may be aggregated to meet the minimum round lot of 100
shares requirement.  Eligible Purchasers may purchase shares of Common Stock
with funds in addition to the cash distributions which they are entitled to
receive in order to purchase (i) the minimum round lot of 100 shares, or (ii)
shares in addition to the number of shares purchasable with their cash
distributions, subject to prorata limitations in the event of

oversubscription. The shares of Common Stock of the Company are listed on the
NYSE and the Pacific Exchange under the symbol "SFY" and application will be
made to list the Common Stock being offered to Eligible Purchasers on the NYSE
and the Pacific Exchange.  The price at which the Common Stock is offered
hereby to Eligible Purchasers is based upon an average of prices as reported by
the NYSE during a period contemporaneous with completion of voting upon the
Proposals.

PARTNERSHIP PROPERTY INTERESTS

   
         The Partnerships' Property Interests consist either of working
interests or non-operating interests in producing oil and gas properties.  Of
the 63 Partnerships, 37 Partnerships, sometimes referred to herein as
"Operating Partnerships," were formed to purchase working interests in such
properties.  The other 26 Partnerships, sometimes referred to herein as
"Pension Partnerships," were designed for tax-exempt investors and were formed
to purchase non- operating interests in such properties.   Pension Partnerships
own a net profits interest that covers multiple working interests owned by an
Operating Partnership, created under a net profits agreement.  Such Pension and
Operating Partnerships are sometimes referred to herein as "Companion"
Partnerships.  If both of the Companion Partnerships approve their Proposals,
the Pension Partnership will sell its interests in oil and gas assets to its
Companion Operating Partnership, which will immediately thereafter sell such
properties it receives as well as its other oil and gas assets to the Managing
General Partner.

         Information regarding the most significant fields in which
Partnerships own Property Interests are set out in detail in each Partnership's
specific Partnership Supplement (as defined) under "The Partnership," including
specific information on those fields in which each Partnership has Property
Interests which constitute 10% or more of the Partnership's PV-10 Value at
December 31, 1997.  A Partnership's "PV-10 Value" is the estimated future net
cash flows (using unescalated prices) from production of proved reserves
attributed to such Partnership's Property Interests, discounted to present
value at 10% per annum.  See "Glossary of Terms."

SUMMARY RISK FACTORS

o        The purchase price to be paid by the Managing General Partner for the
         Partnerships' Property Interests may not represent the highest
         possible prices that might be received for the Partnerships' Property
         Interests in all circumstances.  Such prices might be higher (or
         lower) if these Property Interests were sold on another basis, such as
         at auction or in a negotiated sale.  See "Risk Factors--Conflicts of
         Interest in Purchase of Property Interests by Managing General
         Partner."

   
o        No independent representative was retained on behalf of the Investors
         to negotiate the purchase price to be paid by the Managing General
         Partner for the Partnerships' Property Interests.  Such proposed
         purchase prices have not been negotiated at arm's length and are
         subject to significant conflicts of interest between the Company
         acting both as the purchaser of the Property Interests and as the
         Managing General Partner of the Partnerships.

o        The fair market values (which does not include the 7.5% premium)
         forming the basis of the purchase prices to be paid by the Managing
         General Partner for the Partnerships' Property Interests are the
         Appraisers' estimation of such values.  Year-end 1997 prices, along
         with other then-current market factors, were used as a starting point
         for the Appraisers' analyses.  The Petroleum Engineering Consultants
         (as defined) then made the determination to escalate prices and costs
         at a rate of 3.5% per year over 15 years.  Higher increases in the
         prices for oil and gas or lower increases in costs in the future, if
         any, might result in Investors receiving higher distributions from
         continued operations of the Partnerships than estimated.  However, the
         effect of any higher prices or lower costs is somewhat limited because
         the Partnerships have already produced a substantial majority of their
         oil and gas reserves.  See "Risk Factors--Timing of Sale and Price
         Volatility."

o        Although two estimations of the fair market value of the Property
         Interests for each Partnership forming the basis for the proposed
         purchase price to be paid by the Managing General Partner were
         determined by three independent Appraisers, no opinion was acquired as
         to the fairness of the entire transaction, including but not limited
         to the 7.5% premium over the higher of the two fair market estimations
         by the Appraisers.  The 7.5% premium was determined in the Managing
         General Partner's sole judgment and was not based upon a determination
         by an impartial third party.  Another party intent upon purchasing the
         Property Interests of the Partnerships could have evaluated their
         value on a different basis and offered a different purchase price.

o        If the Proposals are approved by Investors resulting in the
         Partnerships' Property Interests being purchased by the Company, the
         Company will likely further develop the Property Interests by spending
         additional capital on recovery of behind-pipe reserves or developing
         undeveloped reserves.  In such event, Investors will not share in any
         possible increase in value of such Property Interests as they would
         had their Partnership so acted.  However, the Company is hereby
         concurrently offering to Eligible Purchasers up to 2,500,000 shares of
         Common Stock of the Company which they may purchase with the funds
         they would otherwise be entitled to receive upon their Partnership's
         liquidation so that they might share indirectly in any such increase.

o        For the 18 Partnerships formed in the fourth quarter of 1986, the
         first three quarters of 1987, and between the fourth quarter of 1992
         and the second quarter of 1994, a majority of their proved oil and gas
         reserves are non-producing.  Because non-producing reserves are
         traditionally discounted due to future costs that must be incurred to
         recover those reserves and the risk that any drilling will be
         unsuccessful, there is a risk that the discount applied to the
         non-producing reserves by the Petroleum Engineering Consultants could
         be greater than the discount applied by third party purchaser.
         Likewise, any drilling conducted on Property Interests acquired from
         these
    





                                       3
<PAGE>   20
   
         Partnerships may have upside potential, the benefit of which will go
         to the Managing General Partner if it acquires those properties.

o        Investors that are not exempt from federal income tax on an investment
         in their Partnership are required to recognize gain or loss on the
         sale of Property Interests by that Partnership.  See "Summary of
         Federal income Tax Consequences" in their individual Partnership
         Supplements as to whether a particular Partnership's Investors will
         have a gain or a loss.  To the extent that gain is recognized, such
         taxpaying Investors will be required to pay federal income tax.  Tax
         must be paid even if Investors choose to acquire Common Stock with
         some or all of their proceeds from the sales of Property Interests.
         Investors should consult their individual tax advisors to determine
         whether they are subject to any tax under state law.  See "Federal
         Income Tax Consequences of Adoption of the Proposals."

o        In the event an Investor does not otherwise hold Common Stock but
         purchases shares hereunder, such Investor will become a shareholder of
         the Company.  An investment in the Company fundamentally differs from
         an investment in the Partnerships.  The Company's business is
         different and subject to different risks than the Partnerships and the
         Company's results of operations, as well as the price of its Common
         Stock, is affected by many factors different than those affecting the
         Partnerships' results of operations and the price of the Units.
         Additionally, the Company has never paid cash dividends to its
         shareholders and does not anticipate doing so in the future, as
         opposed to regular quarterly cash distributions having been made to
         Investors in the Partnerships.  See "Risk Factors--Risks of Electing
         to Take Common Stock" and "Comparison of Ownership of Units and
         Shares" for further discussion and additional differences and rights
         resultant from being a Swift shareholder in contrast to an Investor.

o        If a Partnership's Companion Partnership does not approve its
         Proposal, it is likely that the Proposals to both Partnerships will be
         withdrawn and the value of their Property Interests reassessed.
         Although in such event, the Managing General Partner will attempt to
         provide a different approach for sale of such Partnerships' Property
         Interests, it is possible that such Partnerships' assets may not be
         sold. All but ten Partnerships have Companion Partnerships.  See "Risk
         Factors--Dependence on Vote of Companion Partnership" and, for
         additional information including, but not limited to, which
         Partnerships do not have companions.  See  "The
         Proposals--Simultaneous Proposal to Companion Partnership."
    

See "Risk Factors" herein and "Risk Factors" in each Partnership's specific
Partnership Supplement.

CONFLICTS OF INTEREST AND BENEFITS TO THE COMPANY

   
         There are substantial conflicts of interest which exist by virtue of
the Managing General Partner acting in that capacity on behalf of all 63
Partnerships while at the same time also being the proposed purchaser of all of
the Property Interests.  Furthermore, the Company proposes to offer Common
Stock to those Investors of Partnerships which, along with their Companion
Partnerships, approve their Proposals.  These conflicts of interests are
discussed below.  For further information, see "Conflicts of Interest" in this
Joint Proxy Statement/Prospectus and the section "Conflicts of Interest" in the
Supplements for each of the Partnerships.

o        If Investors of all of the Partnerships approve the Proposals, the
         Company anticipates, when comparing "100% Case" reserve and balance
         sheet pro forma information to December 31, 1997 Company historical
         data, that its total proved reserves on an equivalent basis will
         increase by approximately 26% and its cash flow and total assets will
         increase by approximately 25% and
    





                                       4
<PAGE>   21
   
         19%, respectively.  Furthermore, the Company intends to invest capital
         in DEVELOPING certain of the properties' non-producing reserves
         acquired from the Partnerships which approve the sale of their
         Property Interests to the Company, depending upon the Company's
         assessment of each property's characteristics and upon changes from
         time to time in the prices of oil and gas.  The Company intends to
         profit from a return on the capital used to purchase the Property
         Interests and by investing  additional capital in their further
         development.
    

o        The terms of the Proposals are established by the Company which is
         also the Managing General Partner of the Partnerships.

o        Neither the Managing General Partner nor a majority of its independent
         directors retained an unaffiliated representative to act on behalf of
         the Partnerships' Investors for the purposes of negotiating the terms
         upon which any such sale to the Managing General Partner would be made
         or for the preparation of a report concerning the fairness of such
         transaction.

o        Benefits accruing to the Company include the following:

         o       The Company will share in the benefits available to Investors
                 through liquidating its Partnership interests and receiving
                 the current value of those interests as a result of such
                 sales.

         o       Because of the purchase by the Company of the Partnerships'
                 Property Interests rather than a third party, the Company will
                 continue to serve as operator of many of the properties in
                 which the Partnerships own interests and will continue to
                 receive operating fees.

See "Conflicts of Interest" herein and "Conflicts of Interest" in each
Partnership's specific Partnership Supplement.

BACKGROUND OF THE PROPOSALS

   
         The Partnerships were formed between 1986 and 1994, with approximately
60% of the Partnerships having been in existence for over 7 years.  As
contemplated when the Partnerships were organized, the hydrocarbon production
of the producing properties in which the Partnerships own interests has
steadily declined over time.  All of the Partnerships own interests in
properties with substantial natural gas reserves, and many of the Partnerships'
reserves are comprised almost totally of natural gas.  The general improvement
in the prices for natural gas over the last several years, relative to such
prices in the mid-1990's, make this an appropriate time, especially in light of
the age of the Partnerships, to consider Proposals to sell their Property
Interests.  For the reasons set out below, the Managing General Partner
believes that the Proposals under which it would purchase  all of the oil and
gas properties owned by the Partnerships are fair to Investors and are
structured in a manner so as to attempt to realize the highest value for the
Partnerships' Property Interests, given that the purchase prices were derived
by choosing the higher of two estimates on a Partnership-by-Partnership basis
of the fair market value of  each of the Partnerships' Property Interests by
three independent Appraisers and adding to that higher number a 7.5% premium.
The purchase of the Property Interests assets of any particular Partnership is
not conditioned upon the purchase of the Property Interests of any Partnership
other than a Partnership's Companion Partnership, if any.
    

See "Special Factors--Background" herein and "Special Factors--Background and
Purpose of the Proposal" in each Partnership's specific Partnership Supplement.

PURPOSE AND EFFECT OF THE PROPOSALS

   
         The Proposals are submitted at this time as part of the Managing
General Partner's obligations to manage the business of the Partnerships and
their investments and to address the timely conclusion of the Partnerships'
activities in light of the purposes for which the Partnerships were formed as
well as  the anticipated length of their operation.  The Managing General
Partner believes that the Proposals are fair to Investors and are structured in
a manner so as to attempt to realize the highest value for the Partnerships'
Property Interests.  The Proposals are subject to a number of conflicts of
interest, which are discussed in greater detail below.
    

See "Special Factors--Purpose and Effect of the Proposals" herein and "Special
Factors--Background and Purpose of the Proposal" in each Partnership's specific
Partnership Supplement.

         Approval of the Proposals will have the following effects:

   
1.       The Managing General Partner will ultimately purchase all of the oil
         and gas assets of each Partnership and its Companion Partnership, if
         any, which approve their respective Proposals;

2.       Such Partnerships, having sold all of their Property Interests, will
         be required to liquidate and distribute their assets (principally the
         cash proceeds from sale of their Property Interests) to their partners
         (including the general partners) in accordance with their respective
         ownership interests in the Partnerships; and

3.       Investors will be given the opportunity to  receive shares of Swift
         Common Stock in amounts that they choose on an individual basis in
         lieu of some or all of the cash they would be entitled to receive upon
         their Partnerships' liquidation.
    

REASONS FOR THE PROPOSALS

         THE REASONS FOR PROPOSING THE SALE OF THE PARTNERSHIP'S PROPERTY
INTERESTS AT THIS TIME ARE DESCRIBED IN DETAIL FOR EACH PARTNERSHIP IN THAT
PARTNERSHIP'S SUPPLEMENT INCLUDED WITH THIS JOINT PROXY STATEMENT/PROSPECTUS
UNDER "SPECIAL FACTORS--REASONS FOR THE PROPOSAL," AND VARY FROM PARTNERSHIP TO
PARTNERSHIP DEPENDING UPON, AMONG OTHER FACTORS, THE NATURE OF PROPERTY
INTERESTS WHICH IT OWNS.  The Managing General Partner believes that it is in
the best interest of Investors for their Partnerships to sell their Property
Interests at this time and to dissolve the Partnerships and make a final
liquidating distribution to its Partners for the reasons discussed below.

         Reasons Common to all Partnerships.  The reasons common to all
Partnerships include: (i) the inherent decline in hydrocarbons produced over
time, which leads to decreasing levels of oil and gas revenues and cash flow
from the Partnerships' Property Interests, compounded by the absence of any
further capital expenditures on the properties in which the Partnerships own
Property Interests, which in turn leads to declining cash distributions to
Investors over time, and (ii) the continuation of fairly steady levels of
certain fixed oil field overhead and operating costs, without regard to the
level of production, and continued direct expenses (such as audits, reserve
reports and tax returns) and general and administrative costs incurred each
year.  As production quantities and revenues continue to decline, the cost per
Mcfe for production and operating costs constitutes an increasingly larger
percentage of per Mcfe revenues.  This increases the risk to the Partnerships
from future price volatility, because the margin between revenue per Mcfe and
production cost per Mcfe continues to narrow, and smaller differences in prices
can consume a larger portion of that margin.  By selling their Property
Interests and liquidating the Partnerships, future overhead and direct expenses
and general and administrative costs will be avoided and the receipt of the
value of the Partnerships' reserves accelerated so that such funds are received
at one time.  This in turn avoids the risk of subjecting future revenues and
cash distributions of Investors to the continued and





                                       6
<PAGE>   23
extreme volatility of oil and gas prices, as well as inherent geological,
engineering and operational risks, which could affect future returns.

         Reasons that Differ Among Partnerships.  Other factors differ from
Partnership to Partnership:

         o       Although the amount differs among Partnerships, a majority of
                 the estimated remaining recoverable reserves of the
                 Partnerships (other than the 16 Partnerships formed during
                 1993 and 1994) have been produced.  Especially for the 39
                 Partnerships with less than a third of their estimated
                 remaining recoverable reserves remaining for future production
                 (all but two of the Partnerships formed prior to the second
                 quarter of 1992), any future increases in oil and gas prices
                 are not likely to have a material positive impact on the
                 return on investment to Investors in those Partnerships.
                 Because of steadily declining levels of production, the
                 Managing General Partner believes that the asset base and
                 future net revenues of many Partnerships which were formed
                 between 1986 and 1992 no longer justify the continuation of
                 the Partnerships' operations, especially when these
                 Partnerships have been in existence for six to twelve years.

         o       For those 18 Partnerships formed in the fourth quarter of
                 1986, in the first three quarters of 1987, and in the period
                 from the fourth quarter of 1992 through the second quarter of
                 1994, a majority of the estimated remaining recoverable
                 reserves attributable to those Partnerships' Property
                 Interests are proved non-producing reserves.  Non-producing
                 reserves generally fall into two categories: (1) undeveloped
                 reserves, which require substantial expenditures by the
                 working interest owners for the drilling of new wells to
                 recover such reserves; and (2) behind-pipe reserves, which are
                 unlikely to be producible for many years because behind-pipe
                 reserves require completion in a different producing zone,
                 which does not take place until production is depleted from
                 the currently producing zone.

                 o        The 14 Partnerships (formed between the fourth
                          quarter of 1992 and the end of the second quarter of
                          1994) have over a third of their estimated remaining
                          recoverable reserves in the undeveloped category.

                 o        The 24 Partnerships formed in the fourth quarter of
                          1986, in the first three quarters of 1987, and in the
                          first three quarters of 1988, between the fourth
                          quarter of 1992 and the first quarter of 1993 have an
                          additional amount of their estimated recoverable
                          remaining reserves (more than 20%) in the behind pipe
                          category.

         Recovery in amounts great enough to significantly impact the results
of those Partnerships' operations and their ultimate cash distributions can
only occur after currently producing zones are depleted after many years, or
with the investment of new capital.  As provided in the Partnership Agreements,
the Partnerships expended all of the Investors' net commitments for the
acquisition of Property Interests many years ago, and they no longer have
capital to invest in improvement of the properties through secondary or
tertiary recovery.   Significant amounts of behind-pipe reserves, combined with
the capital expenditures necessary to recover proved undeveloped reserves, has
negatively affected the willingness of third party joint interest owners in
such properties to engage in further development activities.  When properties
have large quantities of non-producing reserves, the purchase price an
unrelated third party is willing to pay for these Property Interests is likely
to be heavily discounted.  Lastly, sufficient additional capital to drill wells
to produce undeveloped reserves is not available from the Partnerships.  The
most important factor leading to the significant proportion of behind-pipe or
undeveloped reserves currently owned by the Partnerships has been the depletion
of most of the Partnerships' proved producing reserves, resulting in the growth
over time in the proportion of the Partnerships' total assets comprised of
non-producing reserves.  Thus, non-producing reserves which were a





                                       7
<PAGE>   24
small proportion of each Partnership's reserves when its oil and gas assets
were purchased have remained and grown to comprise a larger proportion of the
Partnerships' remaining assets.

         A limited amount (less than 10%) of the capital of the Operating
Partnerships was reserved for workover, completion or development activity, the
Partnerships were not intended to engage in material drilling activities.  The
Partnerships were formed to distribute cash from sale of Partnership's oil and
gas production to Investors on a current basis.  The current level of cash flow
of the Partnerships is not sufficient to pay for meaningful drilling activities
or to support borrowing activities for that purpose.  Even if cash flow were
allowed to be used for drilling by a Partnership's limited partnership
agreement, this would require suspension of cash distributions for an extended
period.

   
         The Managing General Partner believes that this is an appropriate time
for the Partnerships to sell their Property Interests due to its perception of
the marketplace, including estimates as to future oil and gas prices, the cash
flow of the Partnerships and the character of their reserves.  The Managing
General Partner believes that after significantly depleting producing oil and
gas properties, they become less attractive to prospective purchasers because
of less cash flow.  Additionally, the Partnerships' limitations on capital
invested in drilling activities in recent years also makes the Property
Interests less attractive to prospective purchasers.  Although the price of oil
has fallen significantly in 1998, gas prices have declined to a lesser degree.
Given the fact that the reserves of the Partnerships and their recent
production consist principally of gas, this is believed to be a good time to
sell Partnership properties to avoid the risk that gas prices might fall to
levels equivalent to those for oil.  At the current time the marketplace's
perception is that gas prices are likely to increase.  Based upon its
experience in the industry and past historical trends, the Managing General
Partner believes that it is often preferable to sell based upon perceptions of
future prices.  Moreover, the sale at this time by any Partnership in
conjunction with the other 62 Partnerships to whom Proposals have been made
allows the costs of the transactions to be spread among a larger number of
entities, which costs are likely to be much higher if such asset sales were
made on an individual Partnership basis or by small groups of Partnerships over
an extended period of time.
    

MANAGING GENERAL PARTNER'S RECOMMENDATIONS

   
         The Managing General Partner recommends that Investors of each of the
Partnerships vote in favor of their Partnership's Proposal for the reasons
discussed above.  However, no recommendation is made by the Managing General
Partner as to whether Investors should elect to take shares of Common Stock in
lieu of cash for their interest in the distributions.  The Managing General
Partner believes the terms of the Proposals are fair to Investors.  See
"Fairness of Proposed Sale" below, "Special Factors--Background" and
"--Fairness of the Proposed Sale" in each Partnership's specific Partnership
Supplement for the Managing General Partner's assessment of the fairness of the
Proposals.
    

         This recommendation should be evaluated in light of the significant
conflicts of interest which exist by virtue of the Managing General Partner's
fiduciary obligations to the Investors in the Partnerships, and acting as the
purchaser of these Partnerships' oil and gas assets.  Additionally, the general
partners (the Managing General Partner and the Special General Partner) own
either a 10% or 15% interest as general partners in each of the Partnerships,
and the Managing General Partner owns between a 0% and 23.4% interest (an
average interest of 4.1%) in the Partnerships as a limited partner.  Although
the Managing General Partner has attempted to address these conflicts of
interest through the factors discussed under "Fairness of the Proposals" below,
the Managing General Partner's recommendation to Investors in voting upon the
Proposals should be evaluated in light of these significant existing conflicts
of interest.

SPECIAL TRANSACTION COMMITTEE'S SELECTION OF APPRAISERS TO SET FAIR MARKET VALUE

         The Proposals to ultimately sell substantially all of the
Partnerships' Property Interests to the Managing General Partner are discussed
in detail under "The Proposals" and "Special Factors" herein.  The Proposals
present significant conflicts of interest between the Company acting in its
capacity as Managing General Partner of the Partnerships and its actions in its
corporate capacity as the proposed purchaser of the Partnerships' Property
Interests.  See "Risk Factors--Conflicts of Interest" herein and "Conflicts of
Interest" in each Partnership's specific Partnership Supplement.  The Special
Transactions Committee of the Board of Directors of the Company (the "Special
Transactions Committee"), which consists solely of four of the five outside
independent directors of the Company, approved the selection of the Appraisers.
The Special Transactions Committee determined that such conflicts of interest
were best addressed by asking three independent Appraisers, consisting of two
petroleum engineering firms and one investment banking firm, to estimate the
fair market values of the Partnerships' Property Interests, rather than
proposing that the Managing General Partner set such fair market values itself
and asking for an opinion on the fairness thereof from an independent third
party.

         The Appraisers were selected based upon the Special Transactions
Committee's assessment of their professional reputations and qualifications,
capabilities, experience and responsiveness.  The Special Transactions
Committee believes that using three Appraisers working collectively provides
the distinct professional expertise of each firm, and gives the Partnerships
the benefit of the independent analytic methods of the different disciplines of
petroleum engineering and investment banking, resulting in a determination of
fair market values which are both independent and comprehensive, and thereby
protects Investors by addressing the potential conflict of interest in the sale
of such Property Interests to the Managing General Partner.

         The methodology used by the Appraisers in estimating the fair market
values is discussed below under "Special Factors--Independent Appraisal of the
Fair Market Values of Property Interests of the Partnerships" herein.  The
Managing General Partner believes that using this methodology to estimate the
fair market values at which the Property Interests will be purchased from the
Partnerships is fair to Investors, as discussed in detail under "Special
Factors--Fairness of Proposed Sale" herein and "Special Factors--Fairness of
Proposed Sale" in each specific Partnership Supplement.  Also discussed under
"Special Factors--Reasons for the Proposals" herein in each Partnership's
specific Partnership Supplement are the reasons for proposing the sale of such
Property Interests and liquidation of the Partnerships at this time.  A
discussion of the alternatives to such sales and liquidations which were
considered is contained under "Special Factors--Consideration of Alternative
Transactions" herein.  In addition to the foregoing, there are certain risks
involved in the Proposals.  See "--Risks" below, "Risk Factors" herein and
"Risk Factors" in each Partnership's specific Partnership Supplement.

METHODOLOGY OF DETERMINING FAIR MARKET VALUE OF PARTNERSHIPS' OIL AND GAS ASSETS

         The Managing General Partner did not instruct the Appraisers as to
pricing, cost or other economic parameters or methods, or the assessment of
reserves characteristics, nor did it limit the scope of their investigation for
purposes of preparing their appraisals.  The Managing General Partner provided
the petroleum engineering firms with basic evaluation data for their use in
determining Partnerships' reserves and their value.  The petroleum engineering
firms prepared their own reserves audit of the Property Interests.  The
Managing General Partner did not direct the Appraisers as to the amount of
consideration to be paid to the Partnerships for their Property Interests nor
provide any information to the Appraisers on amounts to be paid to Investors.
The amount of consideration to be paid was determined by the Company's Board of
Directors based upon the Appraisers' estimates of the fair market value of
those interests.  The Appraisers did not opine on the fairness of the
transaction to Investors, and the Managing General Partner has not acquired a
separate report or opinion regarding the fairness to Investors of the price at
which the





                                       9
<PAGE>   26
Partnerships' Property Interests will be sold to the Managing General Partner
if the Proposals are approved by Investors.

         The petroleum engineering firms individually audited the estimate of
present value of future net cash flows from the 44 property groups in which
Property Interests are owned by the Partnerships.  The petroleum engineering
firms began their analysis based upon the year-end 1997 PV-10 Value of each
property audited by H.J. Gruy and together they re-evaluated reserve
quantities, projected operating costs and cash flows.  The present value of
this reserves analysis was then derived by escalating year-end 1997 prices
($2.38 per MMBtu and $16.00 per barrel before adjustments for Btu content for
gas and gravity variances for oil as well as transportation charges and
geographic location) and costs by 3.5% per year for 15 years.  This present
value was then adjusted for various individual field risks and risk adjustments
of proved non-producing reserves, proved undeveloped reserves and identified
probable and possible reserves.  The result of this collective analysis by the
petroleum engineering firms was their estimation of the fair market value of
each of the property groups in which Property Interests are owned by the
Partnerships as of December 31, 1997.

         CIBC Oppenheimer's evaluation of each Partnership's Property Interests
began with the PV-10 Value of each property group, as calculated by the Company
and audited by Gruy.  CIBC Oppenheimer then divided the property groups into
two categories.  Those property groups with reserves consisting primarily of
proved developed producing reserves were placed in the "Conventional Case"
category.  Those property groups with significant proved developed
non-producing or undeveloped reserves were placed in the "Non-Conventional
Case" category.  CIBC Oppenheimer then valued each property group by applying
the multiples discussed below under "Independent Appraisal of the Fair Market
Value of Property Interests of the Partnerships--Valuation by CIBC Oppenheimer"
to each property group's PV-10 Value, proved reserves on a BOE basis, and
projected 1998 EBIDTA.  A separate set of multiples was used for property
groups in the Conventional Case category and the Non-Conventional Case
category, respectively.  This provided CIBC Oppenheimer with three estimated
values for each property group.  The average of these three values yielded CIBC
Oppenheimer's estimation of the fair market value of each property group.  CIBC
Oppenheimer then allocated the appropriate portion of the property group's
estimated fair market value to the Partnership based upon the Partnership's
Property Interest in each property group.  The result of this analysis by CIBC
Oppenheimer was its estimation of fair market value of each Partnership's
Property Interests as of December 31, 1997.

See "Specific Factors--Fair Market Value," "--Independent Appraisal of the Fair
Market Value of Property Interests of the Partnerships" herein.

DETERMINATION OF PRICE TO BE PAID TO PURCHASE PARTNERSHIP PROPERTY INTERESTS

         Choice of Higher of Two Appraisals:  The Special Transactions
Committee of the Swift Board of Directors determined that, in keeping with the
definition of Fair Market Value (see "Glossary of Terms"), the higher of these
two estimations on a Partnership-by-Partnership basis of fair market value
represents the Fair Market Value of each Partnership's Property Interests which
are set out for each Partnership in its specific Supplement.  Accordingly, the
fair market value estimation of the Petroleum Consulting Engineers and the fair
market value determined by CIBC Oppenheimer were compared to each other and the
higher of the two for each Partnership was chosen as the Fair Market Value of
each Partnership's Property Interests.

         Decision to Add 7.5% Premium.  The Company determined that paying a
7.5% premium over the appraised fair market value of the Partnerships' Property
Interests was appropriate and fair based upon the factors and for the reasons
discussed herein.  The amount of the premium principally was based upon





                                       10
<PAGE>   27
management's experience in purchasing properties which contain both producing
reserves and drilling potential.  Because the Managing General Partner has
served in that capacity on behalf of all of the Partnerships for a number of
years, it is intimately familiar with the Property Interests owned by each of
the Partnerships.  The Managing General believes that if the Property Interests
were to be sold to a third party purchaser who was not equally familiar with
those interests, it is likely that the purchaser would discount the purchase
price to account for that lack of familiarity and perceived potential risks.
If these interests are purchased by the Company, then the additional cost and
personnel often inherent in making a property acquisition are not required.
Since 1979, the Company, on behalf of itself and others, has gained a wide
range of experience with the valuation of oil and gas properties and the prices
for their purchase and sale, having purchased $478 million of such properties
in 129 separate transactions.  In the judgment of the Company, the purchase of
any Partnership's Property Interests, together with interests in many of the
same properties owned by other Partnerships at approximately the same time,
will result in efficiencies to the Company in aggregating such interests.
Swift's long-term knowledge of the risks involved in these properties means
that it is in a better position to evaluate these risks than third parties.

         No attempt was made to distinguish between the Property Interests
owned by any particular Partnership, nor was any statistical or analytical
study prepared by the Company on a separate basis in the course of determining
the amount of this premium.

         Other purchasers might have determined it inappropriate to pay a
premium, or if so, to pay a premium based upon other factors or in a different
amount.  Because there has been no independent determination to pay this
premium or of its amount, and no fairness opinion has been requested regarding
this premium, conflicts of interest existing in its determination, although the
Managing General Partner believes, based upon its knowledge of the oil and gas
industry, its knowledge of the properties involved, its experience in
purchasing and selling oil and gas properties, and the benefits from purchasing
the Property Interests which are particular to the Company, that the amount
being offered to the Partnerships to purchase their Property Interests is fair.

         Amounts to be Paid to Investors Upon Liquidation of their
Partnerships.  The evaluation of the fair market values of the Property
Interests of the Partnerships were based upon values as of December 31, 1997,
including the fair market value estimates by the Petroleum Engineering
Consultants (using pricing assumptions and reserve quantities at that time)
which were in turn based upon the audit of each of the Partnerships' total
proved reserves at that date by H.J. Gruy.  As is the case with all oil and gas
purchases, the purchase is proposed to be made as of the date which the
properties were evaluated (in this case January 1, 1998).  Obviously, the
quantities of reserves being purchased are reduced by production which takes
place after the evaluation date (net of the lease operating cost incurred to
produce such reserves) but before the purchase takes place.

         Therefore, the actual purchase price to be paid to each Partnership
for its oil and gas assets is the purchase price set out in the table contained
in the Summary and the individual Partnership Supplement for each Partnership,
reduced by the net revenues that have been received by that Partnership for
production during 1998.  Money received by each Partnership from the sale of
such production during 1998 has been paid to such Partnership.  The
Partnerships have continued to make quarterly cash distributions during 1998.
A portion of 1998 revenues, therefore, have already been distributed to their
partners during 1998 and the remainder of revenues from 1998 production will be
distributed as part of that Partnership's liquidating distribution.

         Portion of Purchase Price Payable to the Managing General Partner.
The total purchase price for the oil and gas assets of all 63 Partnerships is
approximately $81 million.  Of this amount, approximately $14 million
represents the portion of the purchase price which is payable to the Managing
General Partner by virtue





                                       11
<PAGE>   28
of the Managing General Partner's interest in the Partnerships.  Approximately
$11 million of this is attributable to its interests as a general partner and
$3 million attributable to the units which it has purchased under the right of
presentment set out in the various Partnership Agreements.  Therefore, the
amount payable to purchase all of the oil and gas assets of all 63
Partnerships, net of the amount distributable to the Managing General Partner
itself upon liquidation of the Partnerships, is approximately $67 million as of
December 31, 1997 before any reduction for 1998 production.

   
See "Special Factors--Collective Analysis of Purchase Price" and "Special
Factors--Determination of Premium Over Fair market Value by the Company" and

of Premium Over Fair Market Value by the Company" in each Partnership's
specific Partnership Supplement.
    

SUMMARY PARTNERSHIP INFORMATION

         The Partnerships include four series of Partnerships (two that own
working interests and two that own non- operating interests) formed between
1986 and 1994 under five publicly offered limited Partnership programs under
which partnerships were formed to acquire interests in producing properties.
Under the earliest of the programs, Swift Energy Income Partners ("SEIP"), 24
Partnerships were formed, all of which own working interests.  These
Partnerships were formed between the fourth quarter of 1986 and the second
quarter of 1990.  Commencing in 1988, 13 Partnerships were formed under the
Swift Energy Managed Pension Assets Partnership program ("SEMPAP"), all of
which Partnerships owned non-operating interests in properties in which the
working interest is held in Partnerships formed under the SEIP program.
Commencing in the fourth quarter of 1991, 26 Partnerships were formed under the
Swift Depositary Interests offering.  One-half (13) of these Partnerships were
formed to purchase working interests as Swift Energy Operating Partners
("SEOP") partnerships.  The remaining 13 Partnerships were formed as Swift
Energy Pension Partners ("SEPP") solely to acquire non-operating interests
(principally net profits interests) in the properties in which the SEOP
Partnerships own the working interests.

         Presented on the following two pages is summary information regarding
each of the 63 Partnerships to which Proposals are being submitted under this
Joint Proxy Statement/Prospectus.  A separate Proposal is being submitted to
the Investors in each of the Partnerships for their respective approval or
rejection.  If the Investors in a particular Partnership vote to reject their
Proposal, then that Partnership will continue its operations.  A vote to reject
the Proposal by a Partnership may adversely affect its Companion Partnership,
if it has a Companion Partnership.  Information is being presented to allow
Investors to evaluate the total assets of each Partnership at year-end 1997 and
the PV-10 Value of each Partnership's total proved reserves at the same date,
and compares the value of each Partnership's assets (using the proposed
purchase price of each Partnership's Property Interests) to the total assets of
the Company and the PV-10 Value of the Company's total proved reserves at the
same date.  The amounts shown for liquidating distributions include
distribution of a Partnership's cash on hand after collection of receivables
and payment of all liabilities, and thus these amounts differ from the purchase
price of a Partnership's Property Interests.

         If all of the Partnerships approve the Proposals, the Property
Interests which would be purchased by the Company would consist of interests in
over 1,200 gross wells covering 93 fields in seven states.  The
Company-operated properties comprise a majority of the PV-10 Value of all such
Property Interests which would be acquired.  In the aggregate, if all of the
interests are acquired, it would increase the Company's total proved reserves
at December 31, 1997, by approximately 26%.  These properties are principally
gas, with 73% of the December 31, 1997 reserve volumes and 69% of 1997
production attributable to these properties comprised of natural gas.  Among
these properties, the principal properties to be acquired are located in the
states of Texas, Oklahoma and Louisiana.  The only three fields which





                                       12
<PAGE>   29
would comprise more than 10% of the aggregate of all Property Interests to be
acquired if all the Proposals are approved (based upon their PV-10 Value at
December 31, 1997) are the following:

         The Weatherford Area in the Anardarko Basin in Caddo and Custer
    Counties of Oklahoma includes the Weatherford and Eakly Fields.  These two
    fields include 108 wells, 40 operated by Swift, producing from the Red Fork
    and Springer formations with over 93% of the total proved reserves as of
    December 31, 1997 comprised of natural gas.  Interests in these fields were
    first acquired in 1989.  The Partnerships' aggregate Property Interests in
    these fields account for approximately 18.5% of the total Partnerships'
    PV-10 Value and 5.58% of the Company's PV-10 Value at year-end 1997.  The
    Company holds no direct working interest in these properties.

         The AWP Field is located in McMullen County in South Texas.  The
    properties to be acquired include interest in 96 wells, all operated by
    Swift, producing from the tight-sand Olmos formation, with over 80% of the
    total proved reserves at December 31, 1997 comprised of natural gas.  These
    properties were first acquired in 1988.  The Partnerships' aggregate
    Property Interests in these fields account for approximately 13.1% of the
    total Partnerships' PV-10 Value and 3.96% of the Company's PV-10 Value at
    year-end 1997.  The Company owns between a 47% and 75% direct working
    interest in the AWP wells in which the Partnerships own an interest, as
    well as up to a 100% working interest in other wells in the AWP Field,
    which is the Company's most significant property.

         The Second Bayou Field is located in Cameron Parish, Louisiana.  The
    properties to be acquired include interest in 28 wells, all operated by
    Fina Oil and Chemical Company.  This field has a substantial amount of
    behind-pipe and undeveloped reserves from multiple pay zones, which is
    common for South Louisiana production.  Over 90% of the total proved
    reserves of this field at December 31, 1997 were comprised of natural gas.
    These properties were first acquired in 1993.  The Partnerships' aggregate
    Property Interests in these fields account for approximately 11.3% of the
    total Partnerships' PV-10 Value and 3.41% of the Company's PV-10 Value at
    year- end 1997.  The Company owns between a 3% and 7% direct working
    interest in these properties.

FAIRNESS OF PROPOSED SALE

   
    The Managing General Partner believes that the entire transaction related
to the Proposals involving the proposed method of sales of the Partnerships'
Property Interests is fair to Investors for the following reasons, without
giving any particular weight to any reason:
    

    1.   The Managing General Partner believes that the most important element
         of the Proposals is the determination of the Fair Market Values of the
         Partnerships' Property Interests.  The prices to be paid by the
         Company to purchase the Partnerships' Property Interests were
         determined in the Managing General Partners' sole judgment by adding a
         7.5% premium to the higher of the Appraisers' two estimates on a
         Partnership-by-Partnership basis of fair market value of the
         Partnerships' Property Interests, done on a Partnership-by-Partnership
         basis.  Two of the three Appraisers are qualified independent
         petroleum engineering firms and the other is an investment banking
         firm.  The factors and methods used by the Appraisers in determining
         Fair Market Value are discussed in detail under "Special
         Factors--Independent Appraisal of the Fair Market Value of
         Partnerships' Property Interests" herein and "Special
         Factors--Collective Analysis of Purchase Price; Premium Over Fair
         Market Value" in each Partnership's specific Partnership Supplement.

   
    2.   No transaction will take place in a particular Partnership unless the
         Proposal is approved by Investors holding at least a majority of the
         interests in such Partnership (without any vote by the Managing
         General Partner) and a similar Proposal is approved by such
         Partnership's Companion Partnership.
    

    3.   The Special Transactions Committee made the determination as to the
         retention of the Appraisers and approved the fair market value
         estimates provided by the Appraisers and recommended the reports of
         the Appraisers to the Board of Directors of the Company.  The Special
         Transactions Committee is comprised solely of independent directors of
         the Company.

    4.   If any of the Proposals are approved by Investors, it is likely that
         the Managing General Partner intends to expend the capital necessary
         to develop various non-producing reserves on the Property Interests
         purchased by the Managing General Partner.  If all of the Property
         Interests which are the subject of the Proposals are acquired by the
         Company, such Property Interests in the aggregate will constitute less
         than 20% of the Company's total assets.  Because the Managing General
         Partner would be the beneficiary of any such increase in value, the
         Managing General Partner is hereby offering to Eligible Purchasers the
         opportunity to purchase up to 2,500,000 shares of Common Stock of the
         Company.  There is no requirement that any purchase of Swift's Common
         Stock be made.  See-- "Offer to Eligible Purchasers" below.

    5.   In structuring the Proposals and related transactions, the Managing
         General Partner considered that any sale of Partnership Property
         Interests, whether to the Managing General Partner or to a third
         party, would be a taxable transaction.  Thus, if an Investor subject
         to income tax on its Partnership investment chooses to use the
         proceeds received on liquidation of that Investor's Partnership to
         purchase Swift Common Stock, tax will still have to be paid on the
         amount of any taxable income resulting from the liquidation of that
         Investor's Partnership, whether or not the Investor has available cash
         proceeds remaining from his liquidating distribution after some or all
         of such proceeds are used to purchase Common Stock.

    The individual Partnership Supplements contain an estimate of the
liquidating net cash distributions payable to Investors if their Partnership's
Proposal is approved, along with an estimate of the net cash distributions to
Investors from their Partnership continuing to operate for the remaining life
of that





                                       16
<PAGE>   33
Partnership's reserves.  In all but three Partnerships, the estimated amount
receivable from continuing operations is higher than the amount which Investors
will receive if the Proposals are approved.  Despite this difference, which
ranges from 3% to 48%, depending upon the particular Partnership, the Managing
General Partner believes that the Proposals are fair.  The estimates of
distributions from continuing operations are based upon continuation of current
oil and gas prices over a 17 to 20 year period.  Continued volatility in the
markets for oil and gas therefore make this estimation subject to significant
variance based upon pricing changes.  In addition, there are significant
operational risks over such a long period of time to which each of the
Partnerships would be subject.   Current cash distributions paid in one lump
sum currently are not subject to these risks.

    The fairness of the Proposals for the 18 Partnerships formed in the fourth
quarter of 1986, the first three quarters of 1987, and between the fourth
quarter of 1992 and the second quarter of 1994, the majority of whose proved
reserves are non-producing, should be assessed in light of the benefit to the
Managing General Partner of being able to use its capital resources to drill
wells to develop undeveloped reserves, in addition to the possible benefit of
holding such interests for a period of time sufficient to allow completion of
wells in different zones in order to produce behind- pipe reserves.

    Notwithstanding the above, determinations made by the Special Transactions
Committee, the independent Appraisers' determination of the fair market value
of the properties, and the payment of a 7.5% premium does not necessarily
remove the substantial conflicts of interest which exist due to the Managing
General Partner acting on behalf of the Partnerships and also acting as the
purchaser of the Property Interests from the Partnerships.  No fairness opinion
was requested or received regarding the ultimate purchase price to be paid by
the Managing General Partner to purchase the Partnerships' oil and gas assets.
Rather than setting the purchase price for Partnership Property Interests
itself, the Managing General Partner determined it would be preferable to
request three different independent Appraisers, using two different appraisal
methods to determine fair market values at which such Property Interests should
be purchased.  The Managing General Partner then chose the higher of the two
values on a Partnership-by-Partnership basis.  The Managing General Partner
believes that adding a 7.5% premium to the highest of the fair market value
determinations made by the three Appraisers only increases the amount to be
paid to Investors upon liquidation of their Partnerships and does not require a
separate fairness opinion.  The Managing General Partner believes that when the
Appraisers rendered their opinion as to the "fair market value" of each
Partnership's Property Interests, inherent within that appraisal was the
appraiser's determination that these "fair market values" were "fair," or such
determination would not have been made.  Consequently, no independent fairness
opinion upon the premium was requested.  The determination of a different third
party purchaser as to the purchase price to be paid might be more or less than
that being proposed to be paid by the Managing General Partner.

         By selling all of their respective oil and gas assets to the Managing
General Partner, proceeds from such liquidating sale will be distributed to the
Partners in the Partnerships and the Partnerships will be liquidated, dissolved
and terminated.  These Proposals are subject to a number of conflicts of
interest, all of which are discussed in greater detail below.  The purpose of
the Proposals is to provide for sale of the Partnerships' oil and gas assets
because it is time that the business of the Partnerships be concluded, and to
do so in a way intended to maximize the sale price of the Partnership's oil and
gas assets.  The Managing General Partner is proposing to purchase these assets
from the Partnerships because it believes that its knowledge of the Properties
allows it to pay the highest price for such assets.  The reasons for proposing
the sale of the Partnerships' Property Interests at this time  are described
below under "Special Factors--Reasons for the Proposal--Reasons for Sale of
Assets at this Time."  This decision was made after full consideration by the
Managing General Partner of its fiduciary obligations to Investors.
Furthermore, the decision to use three Appraisers, rather than one, and to have
the Appraisers actually set the fair market value for purchase of the
properties, rather than the Managing General Partner setting that value and
requesting a fairness opinion and the decision to add the 7.5% premium, was
based upon the Managing





                                       17
<PAGE>   34
General Partner's consideration of the substantial conflicts of interest which
exist in the transactions covered hereby, which are detailed herein.

See "Special Factors--Fairness of Proposed Sale" herein and in each
Partnership's specific Partnership Supplement.

ALTERNATIVE TRANSACTIONS

    The Managing General Partner has given consideration to a number of
different alternatives prior to submitting the Proposals to Investors for their
approval.  These alternatives include continued operation of the properties for
a longer period, offering the Partnerships' Property Interests at auction or
selling them in negotiated transactions.  For the reasons discussed at greater
length under "Reasons for the Proposals" above, the Managing General Partner
believes that sale of the Partnerships' Property Interests at this time is
preferable to continued operation of the Partnerships.  Although in the past,
certain marginal Property Interests have been sold in negotiated transactions
or at auction, the Managing General Partner does not believe that such methods
of sale are likely to maximize the value of the Partnerships' Property
Interests, as discussed above.  Although offering oil and gas properties for
sale at auction is often an efficient means of selling smaller interests in
properties in which the seller is not the operator of the property, auctions
are generally unsuited to the offer and sale of substantial property interests,
may exceed the normal size of properties offered at auction, and may well be
beyond the purchasing capacity of the parties which typically are bidders at
such auctions or might lower the price or the number of interested bidders.

    To the extent that the Managing General Partner is operator of properties
in which a Partnership owns Property Interests, this can and often does
negatively affect the interest of third party auction buyers in purchasing such
properties, as well as the amount a third party auction buyer is likely willing
to pay.  Furthermore, auction buyers are generally not interested in purchasing
properties with non-producing reserves, or will usually apply a large discount
to such reserves.  Many of the Partnerships have Property Interests in
properties with a substantial amount of such reserves.  Additionally, the
transaction cost for auctions are often substantial.  Similarly, negotiated
sales of properties are negatively affected by the same factors regarding
operations of the properties and non-producing reserves, and often require
substantial periods of time for due diligence, negotiation, execution of
agreements and closings.  Purchasers in negotiated transactions are often
interested in only selected properties, which often requires different
properties to be sold to different purchasers, necessitating a large number of
transactions.

    An alternative to the Proposals would be to continue each of the
Partnerships according to its existing business plan.  For the reasons set out
above, principally including the decline in the revenues of each of the
Partnerships while direct costs, general and administrative expenses and
certain fixed oil field overhead and operating costs remain at fixed levels or
decline at a less rapid rate (and in some cases, due to the number of years for
which certain of the Partnerships have been in existence), the Managing General
Partner recommends that Investors vote to approve the Proposals.

See "Special Factors--Consideration of Alternative Transactions" herein.

FEDERAL INCOME TAX CONSEQUENCES

   
    The federal income tax consequences of the sale of substantially all of the
Partnerships' Property Interests and their liquidation may vary depending upon
the type of partnership involved and the tax character of the Investor, as well
as the Investor's individual circumstances.  Generally, sales of the
Partnership properties, as described in the Proposals, are taxable transactions
to Investors of a Partnership that may generate taxable income or tax loss
depending on the particular Partnership.  Investors, however,
    





                                       18
<PAGE>   35
   
that are Tax Exempt Plans that are not subject to acquisition indebtedness on
their Partnership investment and that have only invested in Partnerships that
own non-operating properties generally are not subject to federal income tax on
their share of Partnership income or loss.  The tax consequences resulting from
the sale of Partnership properties are not affected by an Investor's decision
to receive cash or Common Stock upon the applicable Partnership's liquidation.
The purchase of Common Stock is not a taxable transaction for federal income
purposes.  For a more complete discussion of the federal income tax
consequences of a sale of properties and Partnership liquidation, see "Federal
Income Tax Consequences of the Proposals" herein.  An opinion of Special Tax
Counsel is included as an Exhibit to the Registration Statement.  All Investors
interested in electing to receive Common Stock in lieu of cash should read
"Material Federal Income Tax Considerations of Electing to Receive Common Stock
in lieu of Cash Upon Partnership Liquidation" herein.  For information
concerning the federal income tax risks associated with the sale of
substantially all of the Partnerships' Property Interests and the acquisition
of Company Common Stock by Investors, see "Risk Factors--Tax Risks" herein.
    

BENEFITS TO THE MANAGING GENERAL PARTNER

    The Managing General Partner will share the benefits available to Investors
through liquidating its Partnership interests (including both its general
partner's interests and any units its owns) and receiving the same value of
those interests as Investors.  Additionally, the Company intends to profit from
purchasing the Partnerships' Property Interests through a return on capital
used to purchase those oil and gas assets and invest in their development.  By
purchasing the Partnerships' Property Interests itself, Managing General
Partner will be able to maintain its position as operator of certain properties
in which Partnerships own interests.  Consequently, the Managing General
Partner would continue to receive operating fees as operator of those
properties.  Additionally, the purchase of all of the oil and gas assets of the
Partnerships would increase the Company's proved reserves, cash flow and total
assets.  Lastly, if individual Investors in Partnerships which approve the
Proposals elect to purchase Company Common Stock, rather than receiving cash
upon liquidation of their Partnerships, the Company will benefit by using stock
to pay the purchase price, rather than using its available cash resources or
borrowing facilities.

See "Special Factors--Managing General Partner Benefits" herein.

   
NO APPRAISAL OR DISSENTERS' RIGHTS PROVIDED; INVESTOR LISTS; BOOKS AND RECORDS
    

    In connection with the Proposals to sell all of the Partnerships' oil and
gas assets and liquidate the Partnerships, Investors are not entitled to any
dissenters' or appraisal rights such as would be available to shareholders in a
corporation engaging in a merger.  Dissenting Investors are protected under
state law by virtue of the fiduciary duty of the Managing General Partner to
act with prudence in the business affairs of the Partnerships, although
investors would be required to initiate suit to assert claims based upon a
general partner's fiduciary duties under the Texas  Revised Limited Partnership
Act and the terms of each Partnership's limited partnership agreement.

   
    Generally speaking, Investors of each of the Partnerships are entitled to
request copies of Investor lists showing the names and addresses of all
Investors in that Partnership.  The right to receive such Investor lists may be
conditioned upon the Investors' paying the cost of duplication and a showing
that the request is for a reasonable purpose.  Reasonable requests would
include requests for Investor lists for the purpose of challenging or opposing
the Proposals.  Requests for Investor lists may be addressed to the Company at
16825 Northchase Drive, Suite 400, Houston, Texas 77060; Attention: Investor
Relations Department.
    

    The limited partnership agreements of the Partnerships provide that their
books and records (generally limited to the records which are just and
reasonable for Investors to examine and copy) are available for





                                       19
<PAGE>   36
inspection by Investors or their duly authorized representatives at all
reasonable times at the Partnerships' principal offices in Houston, Texas,
although certain oil and gas operational materials may be kept confidential.
For most of the Partnerships, a written request must be received stating a
proper purpose for inspection of such books and records, with the inspection to
be conducted at the Investor's expense.  An Investor may request in writing
without charge copies of a Partnership's limited partnership agreement,
certificate of limited partnership and tax return.

CONSEQUENCES OF A PARTNERSHIP NOT APPROVING ITS PROPOSAL

    If the Investors in a Partnership do not approve its Proposal, such
nonparticipating Partnership will continue to operate as a separate legal
entity with its own assets and liabilities.  There will be no change in its
investment objectives, policies or restrictions, and the nonparticipating
Partnerships will continue to be operated in accordance with the terms of their
Partnership Agreement.  It is also likely that the Proposal to the Companion
Partnership of any such nonparticipating Partnership will be withdrawn even if
a Proposal is approved by Investors of such Companion Partnership.

See "Special Factors--Consequences of Partnership not Approving its Proposal"
herein.

COMPARISON OF PARTNERSHIPS AND THE COMPANY

    The information below highlights a number of significant differences
between the Partnerships and the Company relating to, among other things, form
of organization, investment objectives, policies and restrictions, asset
diversification, capitalization, management structure, compensation and fees,
and investor rights.  These differences are discussed in detail under
"Comparison of Ownership of Units or Shares."  Such section of this Joint Proxy
Statement/Prospectus also includes a summary comparison of the legal rights
associated with the ownership of Units or Shares.

    Partner's judgment as to the timing of sales                liquidation of Company assets
</TABLE>

         Investors in each of the Partnerships expect liquidation of their
investment when the assets of the Partnership are liquidated.  In contrast,
Shareholders are expected to achieve liquidity of their investments by trading
the shares of Common Stock in the public markets.  The Company does not expect
to dispose of its investments within any prescribed periods.

                         Properties and Diversification

         The Company owns an oil and gas portfolio substantially larger and
more diversified than the portfolio of any of the Partnerships or all of the
Partnerships taken together.  Whereas the Company is engaged in an active
drilling program, which involves a higher degree of risk, the Partnerships were
not established for any substantial drilling of oil and gas wells, and do not
have the capital to do so.

SWIFT ENERGY COMPANY

   
         The Company is engaged in the development, exploration, acquisition
and operation of oil and gas properties, with a primary focus on U.S. onshore
natural gas reserves.  As of December 31, 1997, the Company had interests in
over 1,500 oil and gas wells located in 10 states, of which the Company
operated 650 wells representing 91% of its proved reserve base.  At such date,
the Company had proved reserves of 361.5 Bcfe, of which approximately 87% were
natural gas, 60% were proved developed and 93% were located in Texas.  The
Company's primary focus is development and exploration drilling in its two core
areas: the AWP Olmos Field located in South Texas and the Texas Austin Chalk
trend.  The AWP Olmos Field is characterized by long-lived reserves, while the
Austin Chalk trend is characterized by short-lived reserves with high initial
production and rapid decline rates.  These fields accounted for approximately
74% and 15%, respectively, of the Company's proved reserves as of December 31,
1997, and approximately 61% and 19%, respectively, of the Company's production
during 1997.
    

   
         On August 26, 1998, the Company purchased certain producing oil and
gas properties (the "Sonat Properties") from Sonat Exploration Company
("Sonat"), a subsidiary of Sonat Inc.  As a result of the acquisition of the
Sonat Properties (the "Sonat Properties Acquisition"), and assuming the
Proposals are approved by all the Partnerships (collectively, the
"Acquisitions"), the Acquisitions provide the Company with significant proved
reserves as well as additional development and exploratory opportunities in its
core areas.  The Company expects to utilize its operating expertise in these
areas to successfully develop and exploit these properties.  The Acquisitions
will increase the Company's interest in oil and gas wells to over 1,650 wells,
of which the Company will operate approximately 765 wells.  The Company expects 
reserves in the Austin Chalk trend to increase to approximately 26% of proved 
reserves as a result of the Acquisitions.  See "--Recent Developments."
    

   
         The Company maintains a flexible capital spending program in order to
take advantage of the relative economic attractiveness of either drilling or
acquisition opportunities.  Over the last several years, the Company's growth
in reserves and production has resulted primarily from its increased acreage
position and drilling activities in the AWP Olmos Field and in the Austin Chalk
trend.  The Company has budgeted capital expenditures of $241.5 million for
1998, comprised of $145.8 million for the Acquisitions and $95.7 million for
development and exploration.  Approximately 59% of the $95.7 million is
targeted for the continued development of the Company's two core areas.  The
Company is also actively pursuing exploratory drilling opportunities in high
potential projects elsewhere in the Gulf Coast Basin and in New Zealand.
    

   
         In 1997, the Company increased its proved reserves by 40% primarily
from additions through drilling, resulting in the replacement of 522% of 197
production.  The Company's five-year average reserve replacement costs were
$0.76 per Mcfe.  As a result of increased drilling activity, 1997 production
increased 31% over 1996 production.  Due to economies of scale, geographic
concentration and increased production, general and administrative expenses and
production costs have fallen from $0.57 and $0.39 per Mcfe, respectively, in
1992 to $0.14 and $0.35 per Mcfe, respectively, in 1997.  For the six months
ended June 30, 1998, such costs were $0.13 and $0.34 per Mcfe, respectively.
    

See "Business and Properties--General" herein.

BUSINESS STRATEGY

   
         The Company pursues a balanced growth strategy that includes an active
drilling program, strategic acquisitions and advanced technologies.  The
Company's operating philosophy is to increase its reserve base through both
drilling and acquisitions, shifting the balance between the two in response to
market conditions.
    





                                       26
<PAGE>   43
   
         Key elements of the Company's strategy include the following:

         Active Drilling Program.  With the expanded inventory of drilling
prospects that the Company will have following the assumed consummation of both
of the Acquisitions and when economic drilling conditions improve, the Company
intends to pursue an active program of development drilling in its core areas
together with selected step-out and exploratory drilling on its undeveloped
acreage.  Exploratory drilling is based on a "controlled risk" approach,
focusing on regions where the exploration objective would allow the Company to
utilize its technological or geological expertise and that are in close
proximity to known production.  In 1997, the Company drilled 128 net
development wells, 127 of which were in the Company's AWP Olmos Field and
Austin Chalk trend core areas, and seven net exploration wells, of which two
were in such core areas.  During this period, the Company had net drilling
success rates of 97% for development wells and 38% for exploratory wells.  The
Company expects to drill a total of 77 gross wells in 1998, 55 of which had
been drilled as of June 30, 1998 at a capital cost of approximately $45.7
million to the Company.  The Company anticipates that drilling activity in the
AWP Olmos Field and the Austin Chalk trend will represent 59% of the total 1998
drilling budget.  The Company looks to reduce its overall risk exposure with
respect to development and exploration activities by entering into joint
development agreements with industry partners to share capital exposure for any
individual well.  As an example of this strategy, the Company has active joint
development projects with, among others, Union Pacific Resources Company
("UPRC") and Chevron USA production Company ("Chevron") in the Austin Chalk
trend, in which the Company serves as operator of a majority of the wells.

         Strategic Acquisitions.  The Company continuously reviews acquisition
opportunities, including opportunities to acquire properties with significant
proved producing reserves and substantial undeveloped acreage for future
drilling activities.  The Company targets properties located in close proximity
to its current reserves, where such reserves can be increased through
development drilling and where operating efficiencies can be achieved.  Using
these criteria, the Company employs a disciplined, market-driven approach to
acquisitions to augment its drilling program.  The Company has conducted an
ongoing acquisition program since its inception.

         Advanced Technologies.  In order to minimize the risks associated with
development and exploration drilling and enhance operating efficiencies, the
Company has devoted considerable resources to developing advanced technological
expertise.  These technologies include 2-D and 3-D seismic analysis, amplitude
versus offset (AVO) studies and detailed formation depletion studies.  The
Company has also attained substantial expertise in horizontal well drilling
technology, having participated as of June 30, 1998 in 70 such wells in the
Austin Chalk trend, 62 of which have been successful.  Additionally, the
Company uses innovative fracturing methods, coiled tubing technology and
computer telemetry to monitor well performance.  As a result of these
technologies, the Company has enhanced its production yields while reducing its
costs per Mcfe.  Application of thee technologies has enabled the Company to
achieve historical drilling success rates that exceed applicable U.S. industry
averages.

RECENT DEVELOPMENTS

   
         In addition to the proposed acquisition of the Partnerships' Property
Interests (sometimes referred to herein as the "Partnership Properties
Acquisition"), the Company recently consummated the following transactions:

         Sonat Properties Acquisition.  On August 26, 1998, the Company
purchased from Sonat, effective April 1, 1998, the Sonat Properties for
approximately $87.6 million in cash.  As of April 1, 1998, estimated

proved reserves for the Sonat Properties were 91.1 Bcfe, of which approximately
56% was natural gas, with 1997 production of 22.0 Bcfe, of which approximately
51% was natural gas.  The properties include 156 producing oil and natural gas
wells in the Brookeland Field in Southeast Texas and the Masters Creek Field in
Western Louisiana, 21 saltwater disposal wells, a 20% interest in two natural
gas plants, associated production facilities and working interests averaging
50% in approximately 200,000 undeveloped gross acres containing more than 50
drilling locations. The Company  became operator of 113 of the 156 wells.  The
two gas plants have combined capacity of 250 Mmcfe per day, and in 1997 had
operating cash flow of $2.8 million.  UPRC is the operator of both plants.

         Acquisition of the Sonat Properties extends one of the Company's core
areas through the addition of producing reserves that will significantly
increase the Company's production on a short-term basis.

         New Credit Facility.  On August 18, 1998, the Company closed on a
$250.0 million revolving line of credit (the "New Credit Facility"), of which
Bank One, Texas, National Association, the lead bank, has committed $37.5
million and has syndicated the balance with a group of nine other banks.  The
New Credit Facility is subject to an initial borrowing base of $170.0 million.
However, an additional $30.0 million will be added to this borrowing base upon
consummation of the Partnership Properties Acquisition.  As of September 1,
1998, $19.2 million of the $170.0 million borrowing base was available to the
Company.  The New Credit Facility replaces all of the Company's prior bank
credit facilities.  The borrowing base will be redetermined semi-annually on
the basis of reserve reports and other information available to the lenders.
In addition, the lenders may, at their discretion, make a redetermination of
the borrowing base at any time including in connection with a request by the
Company to redetermine the borrowing base, the incurrence of additional debt
and the sale or transfer of properties by the Company.

         Borrowings under the New Credit Facility bear interest, at the option
of the Company, either at (i) the lead bank's prime rate, currently 8.5%, or
(ii) adjusted LIBOR plus the applicable margin, which increases as the level of
outstanding debt increases.  The New Credit Facility extends until August 18,
2002.  The terms of the New Credit Facility include restrictions such as
limitations on debt obligations, certain liens, dividends (not to exceed $2.0
million annually), a $15.0 million limit on repurchases by the Company of its
Common Stock, as well requirements as to maintenance of certain minimum
financial ratios (principally pertaining to working capital, debt and equity
ratios).

(b)  As of January 1, 1994, the Company changed its revenue recognition policy
     for earned interests. Accordingly, for 1997, 1996, 1995, 1994, and for the
     six months ended June 30, 1998 and 1997, "Fees and Earned Interests" do not
     include earned interests.
    
(c)  Amounts have been retroactively restated in all periods presented to: (a)
     an equivalent change in capital structure as a result of two 10% stock
     dividends, one in September 1994, the other in October 1997 (see Note 2 to
     the Consolidated Financial Statements); and (b) the adoption of Statement
     of Financial Accounting Standards No. 128, "Earnings per Share" (see Note 2
     to the Consolidated Financial Statements).
(d)  For purposes of calculating the ratio of earnings to fixed charges, fixed
     charges include interest expense, capitalized interest, amortization of
     debt issuance costs and that portion of non-capitalized rental expense
     deemed to be the equivalent of interest. Earnings represents income before
     income taxes from continuing operations before fixed charges. The Company's
     Management uses the ratio of earnings to fixed charges to determine the
     extent to which the Company's earnings are adequate to cover fixed charges
     (as defined).

                 SUMMARY PRO FORMA CONSOLIDATED FINANCIAL DATA
                            OF SWIFT ENERGY COMPANY
 
   
    The summary historical consolidated financial data of the Company for the
year ended December 31, 1997 has been derived from the audited consolidated
financial statements of the Company. The summary historical consolidated
financial data of the Company as of and for the six month period ended June 30,
1998 were derived from the unaudited condensed consolidated financial statements
of the Company.
    
 
   
    The unaudited summary pro forma financial data is based on the Company's
historical financial statements, adjusted to give effect to the following
scenarios (i) the purchase of substantially all of the oil and gas assets (the
"Partnership Properties Acquisition") of all 63 Partnerships ("100% Case") for
(a) all cash or (b) cash and 2.5 million shares of Common Stock at an assumed
price of $18 per share and the Sonat Properties Acquisition consummated for all
cash and (ii) the effect of the approval of the Proposals by those 48
Partnerships with the lowest levels of net cash provided by operating
activities, selected in ascending order until the group of such Partnerships
collectively represent approximately 50% of the combined net cash provided by
operating activities for the six months ended June 30, 1998 of all 63
Partnerships ("50% Case") for (a) all cash or (b) 2.1 million shares of Common
Stock at an assumed price of $18 per share and the Sonat Properties Acquisition
consummated for all cash. The above scenarios assume that the Company uses
available cash and borrowings under the new $250 million credit facility due
2002 (the "New Credit Facility") to satisfy the required cash outlay to fund the
Partnership Properties Acquisition and the Sonat Properties Acquisition
(together "the Acquisitions"). The unaudited summary pro forma statements of
income data assumes the Partnership Properties Acquisition and the Sonat
Properties Acquisition occurred January 1, 1997. The unaudited summary balance
sheet data assumes the Partnership Properties Acquisition and the Sonat
Properties Acquisition occurred as of June 30, 1998. The unaudited summary pro
forma data is not necessarily indicative of the results that actually would have
occurred if the Partnership Properties Acquisition and the Sonat Properties
Acquisition had been in effect on the dates indicated or which may be obtained
in the future.
    
 
    The information presented below should be read in conjunction with the
Consolidated Financial Statements and related notes thereto, the Unaudited Pro
Forma Consolidated Financial Statements, "Management's Discussion and Analysis
of Financial Condition and Results of Operations," and other financial
information included elsewhere in the Joint Proxy Statement/Prospectus.

(a)  For purposes of calculating the ratio of earnings to fixed charges, fixed
     charges include interest expense, capitalized interest, amortization of
     debt issuance costs and that portion of non-capitalized rental expense
     deemed to be the equivalent of interest. Earnings represents income before
     income taxes from continuing operations before fixed charges. The Company's
     management uses the ratio of earnings to fixed charges to determine the
     extent to which the Company's earnings are adequate to cover fixed charges
     (as defined).

(a)  Adjusted to give effect to the Acquisitions as if they had occurred January

(b)  Changes in quantity estimates and the PV-10 Value and standardized measure
     are affected by the change in crude oil and gas prices at the end of each
     year. While the Company's total proved reserves quantities (on an MMcfe
     basis) at year end 1997 increased by 40% over reserves quantities a year
     earlier, the PV-10 Value and standardized measure of those reserves
     decreased 26% and 20%, respectively, from the PV-10 Value and standardized
     measure at year end 1996. This decrease was almost totally due to the
     higher year end 1996 prices. If year end 1997 PV-10 Value and standardized
     measure used year end 1996 prices, there would have been an increase in the
     PV-10 Value and standardized measure from year end 1996 to year end 1997
     comparable to the 40% increase in the total proved reserves quantities
     during that same period.
 
(c)  Calculated for a three-year period ending with the year presented by
     dividing total acquisition, exploration and development costs (excluding
     future development costs) incurred during such period by net reserves added

(a) The Investors' per $100 investment calculations are based upon the number of
    $100 investments into the total combined Partnerships' Investor original
    capital contributions. The Investors' original capital contributions for the
    combined Partnerships totaled $331,427,600 for 1995 through June 30, 1998,
    $319,308,800 for 1994 and $283,970,600 for 1993. The per $100 investment is
    presented in order to achieve a comparable measure for all Partnerships, as
    interests in the Partnerships were sold on a basis of either $1.00 units,
    $100 units or $1,000 units.
    
 
(b) Represents the total combined Partnerships fair market value of the
    Partnerships' Property Interests. The fair market value was derived from the
    higher of the Appraisers' fair market valuation estimates for each
    Partnership and was used in determining the purchase price for the
    Partnership Property Acquisitions. See "Summary -- Summary Partnership
    Information" for the fair market value of each Partnership.
 
(c) For purposes of calculating the ratio of earnings to fixed charges, fixed
    charges include interest expense capitalized interest, amortization of debt
    issuance costs and that portion of non-capitalized rental expense deemed to
    be the equivalent of interest. Earnings represents income before income
    taxes from continuing operations before fixed charges.

                                  RISK FACTORS

   
         In addition to the other information contained in this Joint Proxy
Statement/Prospectus, the following factors should be considered carefully in
evaluating an investment in the Shares offered hereby.  The statements
contained herein that are not historical facts are "forward-looking statements"
as that term is defined in Section 21E of the 1934 Act, and therefore involve a
number of risks and uncertainties.  Such forward-looking statements may be or
may concern, among other things, the Company's future financial position,
business strategy, budgets, projected costs, plans, capital expenditures,
drilling activity, development activities, cost savings, production efforts and
volumes, hydrocarbon reserves, hydrocarbon prices, liquidity, regulatory
matters and competition.  Such forward-looking statements generally are
accompanied by words such as "plan," "budget," "estimate," "expect," "predict,"
"anticipate," "projected," "should," "believe," or other words that convey the
uncertainty of future events or outcomes.  Such forward-looking information is
based upon management's current plans, expectations, estimates and assumptions
and is subject to a number of risks and uncertainties that could significantly
affect current plans, anticipated actions, the timing of such actions and the
Company's financial condition and results of operations.  As a consequence,
actual results may differ materially from expectations, estimates or
assumptions expressed in or implied by any forward-looking statements made by
or on behalf of the Company, including those regarding the Company's financial
results, levels of oil and gas production or revenues, capital expenditures,
and capital resource activities.  Among the factors that could cause actual
results to differ materially are: fluctuations of the prices received or demand
for the Company's oil and natural gas; the uncertainty of drilling results and
reserve estimates; operating hazards; requirements for capital; general
economic conditions; competition and government regulations; as well as the
risks and uncertainties set forth in "Risk Factors" below, including, without
limitation, the portions referenced above and the uncertainties set forth from
time to time in the Company's other public reports, filings and public
statements (collectively, "Cautionary Statements").  Also, because of the
volatility in oil and gas prices and other factors, interim results are not
necessarily indicative of those for a full year.  All subsequent, written and
oral forward-looking statements attributable to the Company or persons acting
on its behalf, are expressly qualified in their entirety by the Cautionary
Statements.
    

         Prior to making an investment decision, Investors should consider all
of the information in this Joint Proxy Statement/Prospectus and in their
specific Partnership Supplement and should give careful consideration to the
risks involved, including those summarized below:

RISKS OF THE PROPOSALS

CONFLICTS OF INTEREST

   
         If the Proposals are approved, the Partnerships' Property Interests
ultimately would be sold to the Managing General Partner at a purchase price
that has been set by the Special Transactions Committee of the Board of
Directors of the Company based on the valuation estimates of the Appraisers
plus a 7.5% premium.  This purchase price may not represent the highest
possible prices that might be received for the Partnerships' Property Interests
in all circumstances.  It is possible that a higher or lower price might be
received if the properties were sold on an individual basis.  A different price
(either higher or lower) might also be received if certain properties were sold
at auction or in a negotiated sale.  The Company has not attempted to sell or
locate partners for the Partnerships' Property Interests by any of these means.
    

   
    



                                       35
<PAGE>   52
NO FAIRNESS OPINION

         Although the fair market value of the Property Interests forming the
basis for the proposed purchase price to be paid by the Managing General
Partner was determined by three independent Appraisers, no opinion was acquired
as to the fairness of the 7.5% premium over the highest of the Appraisers' fair
market value for each Partnership's Property Interests.  The 7.5% premium was
determined in the Managing General Partner's sole judgment and was not based
upon a determination by an impartial third party.  It is possible that another
party intent upon purchasing the Property Interests in the Partnerships would
have offered a different Purchase Price.

LACK OF INDEPENDENT REPRESENTATION

   
         No independent representative was retained to act on behalf of the
Investors in structuring and negotiating the terms and conditions (including
the consideration to be received) of the Proposals.  The proposed purchase
prices have not been negotiated at arm's length and are subject to significant
conflicts of interests between the Company acting both as the purchaser of the
Partnerships' Property Interests and as the Managing General Partner of the
Partnerships.  If an independent representative had been retained for the
Investors, the terms of the Proposals might have been different and possibly
more favorable to the Investors.
    

TIMING OF SALE AND PRICE VOLATILITY

   
         The fair market values (which does not include the 7.5% premium)
forming the basis of the purchase price to be paid by the Managing General
Partner for the Partnerships' Property Interests are based upon the Appraisers
estimations of such values.  Year-end 1997 prices, along with other
then-current market factors, were used as a starting point for the Appraisers'
analyses.  The petroleum engineer consultants then made the determination to
escalate prices and costs at a rate of 3.5% per year over 15 years.  Greater
increases in the prices or lesser increases in costs in the future might result
and Investors would receive higher distributions from continued operations of
the Partnerships than estimated.  However, the effect of any higher prices or
lower costs is somewhat limited because the Partnerships have already produced
a substantial majority of their oil and gas reserves.
    

DEPENDENCE ON VOTE OF COMPANION PARTNERSHIP

         If a Partnership's companion Partnership does not approve its Proposal
to sell all of its oil and gas assets and liquidate, it is likely that the
Proposals to both such Partnerships will be withdrawn and the value of their
Property Interests reassessed.  This could occur, even though a Proposal is
approved by Investors of the other Partnership, due to the decrease in value of
the Property Interests involved when the working and non-operating interests
are separated.  All but ten of the 63 Partnerships have companion Partnerships.
See "The Proposal--Simultaneous Proposal to Companion Partnership" for
additional information including, but not limited to, which Partnerships do not
have companions.  Although in such event the Managing General Partner will
attempt to provide a different approach for sale of such Partnerships' Property
Interests, it is possible that such Partnerships' assets may not be sold.





                                       36
<PAGE>   53
   
VOLATILITY OF AND RELATIONSHIP BETWEEN VALUE OF PROPERTY INTERESTS AND STOCK
PRICE

         The Managing General Partner intends to invest capital in drilling
activities in the fields that comprise the Property Interests it proposes to
purchase from the Partnerships.  Such investment may and  future drilling
activity by third parties in or near such fields could increase the value of
such Property Interests.   Investors will not share in any possible increase in
value of such Property Interests.  In addition, certain of this drilling
activity is likely to consist of higher risk development or exploratory
drilling.  However, the Company is hereby offering up to 2,500,000 shares of
Common Stock directly to Investors of Partnerships that along with their
Companion Partnerships, if any, approve the Proposals.  Investors who elect to
receive such stock may share indirectly in any increase in the value of the
Property Interests purchased by the Company through increase in the price of
the Common Stock, however, such Investors are also subject to the risk that the
price of the Common Stock could decline even if the value of such Property
Interests purchased by the Company increase.
    

         For the 18 Partnerships formed in the fourth quarter of 1986, the
first three quarters of 1987, and between the fourth quarter of 1992 and the
second quarter of 1994, a majority of their proved oil and gas reserves are
non- producing.  Because non-producing reserves are traditionally discounted
due to future costs which must be incurred to recover those reserves and the
risk that any drilling will be unsuccessful, there is a risk that the discount
applied to the non-producing reserves by the Petroleum Engineering Consultants
could be greater than the discount applied by third party purchaser.  Likewise,
it is likely that any drilling conducted on Property Interests acquired from
these Partnerships has upside potential.  The benefit of which will go to the
Managing General Partner if it acquires those properties.

POSSIBLE DECREASE IN DISTRIBUTIONS TO INVESTORS DUE TO INTERIM PRODUCTION

         The amounts available for distribution to Investors if the Proposals
are approved are estimated under "The Proposal--Estimates of Liquidating
Distribution Amount."  The amounts estimated thereon have been reduced by
estimated cash distributions to Investors between January 1, 1998 and [June
30,] 1998.  Thus in analyzing the Proposal, amounts distributed upon
liquidation could be smaller than, or vary from, those shown.

RISKS OF ELECTING TO TAKE COMMON STOCK

TRADING PRICE OF SHARES

         There is substantial uncertainty as to the prices at which the Shares
will trade following consummation of the Proposals.  It is not known whether
the prices at which the Shares will trade will be greater or less than the (i)
price at which the Shares will be sold hereunder or (ii) the cash distribution
the Investor could receive in lieu of subscribing for any Shares.  As with
other equity securities, the value of the Shares will depend upon various
market conditions, which change from time to time.  The conditions that may
affect the value of the Shares include, but are not limited to, the following:
the price of oil and gas; institutional interest in the Company; the Company's
financial performance; and general stock market conditions.

DEMAND IN MARKET

         There can be no assurance that demand will rise for the Shares after
the consummation of the Proposals.  Whether such demand rises will depend on,
among other things, the Company's performance, market yield expectations,
institutional interest in the Company and perceptions regarding the Company's
growth potential.

UNCERTAINTIES AT TIME OF VOTING

         Prior to completion of the solicitation to which this Joint Proxy
Statement/Prospectus relates, it is not known which of the Partnerships will
approve the Proposals.  Investors, therefore, do not know the extent to which
the Company will draw upon its line of credit to purchase the Property Interest
or the extent of dilution to shareholder ownership as a result of this
Offering.

CHANGE IN NATURE OF INVESTMENT

         By electing to receive shares of Common Stock instead of continuing to
hold Units, the nature of an Investor's investment fundamentally changes.
These changes are due in part to differences in the governing documents under
which the Company and Partnerships are organized and the fact that the Company
is subject to federal and state statutes, regulations and laws applicable to
corporations and, subject to the provisions of the Code applicable to
corporations.  The Partnerships are instead subject to the state statutes,
regulations and laws applicable to partnerships and subject to the provisions
of the Code applicable to entities taxed as partnerships.  Certain of these
differences are summarized under "Comparison of Ownership of Units and Shares"
and should be carefully considered by the Investors in assessing how to vote on
the Proposals.  Several of these factors may increase the risks of the
Investors if they elect to receive Shares of Common Stock in lieu of cash
distributions or continuing to hold Units in the Partnerships.

         Length of Investments.  Investors in each of the Partnerships expect
liquidation of their investment when the assets of the Partnership are
liquidated, which liquidations were to occur within 5 to 10 years of the
Partnership's organization.  In contrast, shareholders are dependent upon the
secondary securities markets to achieve liquidity of their investments by
trading the Shares.  Such secondary market may not fully reflect the
liquidation value of the Company's assets.

         Potential Leverage.  It is expected that the Company may incur
indebtedness substantially beyond that incurred for any of the Partnerships.
None of the Partnerships has incurred significant indebtedness, nor is it
expected that any such indebtedness would be incurred by the Partnerships in
the future.  Investment in the Shares would, accordingly, expose the Investors
to the risks associated with substantial leverage.

RETAINED EARNINGS IMPACT UPON MARKET VALUE

   
         The market value of the Company's Common Stock is generally believed
to be based primarily upon a multiple of net cash receipts, whether from
operations or sales or refinancings, and a factor for the market's expectation
of the likelihood of a continuation of that cash flow and secondarily upon the
appraised value of the underlying assets.  For such reasons, the Shares may
trade at prices below the value of the underlying assets divided by the number
of outstanding shares of Common Stock.  To the extent the Company retains
operating cash flow for investment purposes, working capital reserves or other
purposes, such retention of funds, while increasing the value of the Company's
underlying assets, may not correspondingly increase the market value of the
Shares.  Furthermore, the Company has never paid any cash dividends and does
not expect to do so in the foreseeable future.

<PAGE>   55
DILUTION UPON ISSUANCE OF SHARES

         The issuance of the Shares will have the effect of diluting existing
shareholders of the Company.  The Company has the right to issue, at the
discretion of the Board of Directors, additional equity securities, including
additional shares of Common Stock.  Such equity securities can be issued upon
such terms and at such prices as the Board of Directors may establish.  Should
additional equity securities be sold, such sales would dilute the interests of
all Shareholders.  In addition, the Company may in the future issue preferred
stock that might have priority over the Common Stock as to distributions and
liquidation proceeds.  See "Investment Policies and
Restrictions--Capitalizations--Common and Preferred Stock."

RISKS OF INVESTMENT IN THE COMPANY

VOLATILITY OF OIL AND GAS PRICES AND MARKETS; CEILING TEST WRITEDOWNS

   
         The Company's revenue and profitability are substantially dependent
upon prevailing prices of oil and natural gas.  In the months preceding the
date of this Joint Proxy Statement/Prospectus, oil prices dropped to 12-year
lows and gas prices remained volatile.  There can be no assurance that oil and
gas prices will improve.  Continued declines, or prolonged pricing at current
levels, could have a material adverse effect on the Company's results of
operations and financial condition, could impact the Company's ability to find
drilling partners or to otherwise fund development and exploration programs,
and may reduce the amount of the Company's reserves that can be produced
economically.

         Prices for oil and natural gas are also subject to considerable
volatility.  Price volatility makes it difficult to estimate the value of
producing properties for acquisition and often causes disruption in the market
for oil and natural gas producing properties, as buyers and sellers have
difficulty agreeing on such value.  Furthermore, price volatility makes it
difficult to budget for and project the return on acquisitions and development
and exploration projects.  Prices for oil and natural gas are likely to
continue to be subject to wide fluctuation in response to relatively minor
changes in the supply of and demand for oil and natural gas, market uncertainty
and a variety of additional factors beyond the control of the Company.  These
factors include the level of consumer product demand, weather conditions,
domestic and foreign governmental regulations, the price and availability of
alternative fuels, world political conditions, the foreign supply of oil and
natural gas, the price of oil and gas imports and overall economic conditions.
From time to time, oil and gas prices have been depressed by excess domestic
and imported supplies, as is the current situation.  In addition, as a result
of changes in recent years in the natural gas market regulatory structure and
volatility in the market price of natural gas, most producers and purchasers
are unwilling to enter into long-term purchase and sale contracts.
Accordingly, most of the Company's gas production is sold on the "spot market,"
where producers and purchasers negotiate sales on a short-term (usually a
30-day) basis.  Accordingly, the stability of the Company's future revenues is
vulnerable to short-term fluctuations in the price of natural gas.  See
- --Effect of Price Risk Management.

         Under Commission regulations applicable to entities that account for
their investments in oil and gas properties using the full-cost accounting
rules, on a quarterly basis the Company confirms that the after-tax PV-10 Value
of its proved reserves (plus certain amounts for unproved properties) exceeds
the capitalized costs of oil and gas properties and deferred taxes carried on
its balance sheet.  This "ceiling test" must be performed using oil and gas
prices at the end of the applicable period, rather than historical amounts or
averages calculated over longer periods.  In addition, the quantity of reserves
to which the test is applied may be reduced to the extent depressed pricing
makes it uneconomic to produce.  As of June 30, 1998, gas prices
    





                                       39
<PAGE>   56
   
were $2.59 per Mcf and oil prices were $12.32 per Bbl.  Applying such prices to
the Company's June 30, 1998 estimated reserves results in a ceiling test
cushion of approximately $23.4 million.  Declines in oil and gas prices below
the June 30, 1998 levels could require a writedown of the value of the
Company's oil and gas properties.  Additionally, the Company calculates its
ceiling test on a country by country basis, and a negative outlook in a
particular country could result in a writedown even if prospects in other
countries remain positive. Although any such writedown would not affect cash
flow from operating activities, it would constitute a charge to earnings and
would decrease stockholders' equity.  See "Management's Discussion and Analysis
of Financial Conditions and Results of Operations--General--Proved Oil and Gas
Reserves."

LEVERAGE AND DEBT SERVICE

         After giving effect to the Sonat Properties Acquisition and the
Proposals (assuming the 100% Case All Cash Partnership Properties Acquisition),
the Company will have indebtedness that is substantial in relation to its
stockholders' equity.  As of June 30, 1998, on a pro forma basis after giving
effect to these transactions,  the Company would have had approximately [$275]
million of outstanding total consolidated indebtedness and stockholders' equity
of approximately [$163] million.  The Company's level of indebtedness will have
several important effects on its future operations, including (i) a significant
portion of the Company's cash flow from operations will be dedicated to the
payment of interest on its indebtedness and will not be available for other
purposes, (ii) covenants contained in the Company's debt obligations will
require the Company to meet certain financial tests, and other restrictions
will limit its ability to borrow additional funds or to dispose of assets and
may affect the Company's flexibility in planning for, and reacting to, changes
in its business, including possible acquisition activities, (iii) the Company's
ability to obtain financing in the future for working capital, capital
expenditures, acquisitions, general corporate purposes or other purposes may be
impaired and (iv) the Company's leveraged position may make the Company more
vulnerable to economic downturns and may limit its ability to withstand
competitive pressures.  The Company's ability to meet its debt service
obligations and to reduce its total indebtedness will depend upon the Company's
future performance, which will be subject to general economic conditions and to
financial, business and other factors affecting the operations of the Company,
many of which are beyond its control.  See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."
    

REPLACEMENT AND EXPANSION OF RESERVES

   
         The Company's continued success is largely dependent on its ability to
replace and expand its oil and gas reserves through the development of and
exploration for oil and gas reserves and the acquisition of producing
properties, both of which involve substantial risks.  Without successful
drilling or acquisition ventures, the Company will be unable to replace the
reserves being depleted by production, and its assets, revenues, cash flows and
reserves would decline.  There can be no assurance that the Company's
development and exploration and acquisition activities will result in the
replacement of, or additions to, the Company's reserves, or that it will have
continuing success at drilling productive wells at economically viable costs.

DEVELOPMENT AND EXPLORATION RISKS

         Development and exploration  of oil and gas reserves involve a high
degree of risk that no commercial production will be obtained or that the
production will be insufficient to recover drilling and completion costs.  The
cost of drilling, completing and operating wells is often uncertain and during
the past several years such costs paid by the Company to providers in the
service sector of the industry have increased, due primarily to higher demand
for drilling rigs and other equipment and services (as reflected in the
Company's increasing reserve replacement costs).  The Company's drilling
operations may be curtailed, delayed or canceled as a
    





                                       40
<PAGE>   57
   
result of numerous factors, including title problems, weather conditions,
compliance with governmental requirements and shortages or delays in the
delivery of equipment.  Furthermore, completion of a well does not assure a
profit on the investment or a recovery of drilling, completion and operating
costs.  See "Business and Properties--Development and Exploration Drilling
Activities."

         The Company currently emphasizes development and exploration of
natural gas reserves.  The marketability of the Company's production depends
upon the availability and capacity of gas gathering systems, pipelines and
processing facilities.  The unavailability or lack of capacity thereof could
result in the shut-in of producing wells or the delay or discontinuation of
development plans for properties.  In addition, the effects of the foregoing
could be exacerbated by the fact that the Company's operations are
geographically concentrated in its two core areas, making the Company more
vulnerable to an adverse change in conditions in its operating area than more
geographically diversified competitors might be.
    

RISKS ASSOCIATED WITH ACQUISITIONS

         The Company's growth since its inception has been attributable in
significant part to acquisitions of producing properties.  The Company expects
to continue to evaluate and, where appropriate, pursue acquisition
opportunities on terms management considers favorable to the Company.  There
can be no assurance that suitable acquisition candidates will be identified in
the future, or that the Company will be able to finance such acquisitions on
favorable terms.  In addition, the Company competes against other companies for
acquisitions, and there can be no assurance that the Company will be successful
in the acquisition of any material property interests.  Furthermore, there can
be no assurances that any future acquisitions made by the Company will be
integrated successfully into the Company's operations or will achieve desired
profitability objectives.

         The successful acquisition of producing properties requires an
assessment of recoverable reserves, exploration potential, future oil and
natural gas prices, operating costs, potential environmental and other
liabilities and other factors beyond the Company's control.  In connection with
such an assessment, the Company performs a review of the subject properties
that it believes to be generally consistent with industry practices.
Nonetheless, the resulting assessments are necessarily inexact and their
accuracy inherently uncertain, and such a review may not reveal all existing or
potential problems, nor will it necessarily permit the Company to become
sufficiently familiar with the properties to fully assess their merits and
deficiencies.  It is generally not feasible for the Company to review in detail
every property it purchases and all records with respect to such properties.
Moreover, even a detailed review of properties and records may not necessarily
reveal existing or potential problems, nor will it permit a buyer to become
familiar enough with the properties to assess fully their deficiencies and
capabilities.  Evaluation of future recoverable reserves of oil, gas and
natural gas liquids, which is an integral part of the property selection
process, is a process that depends upon evaluation of existing geological,
engineering and production data, some or all of which may prove to be
unreliable or not indicative of future performance.  See "--Uncertainty of
Estimates of Reserves and Future Net Revenues."  To the extent the seller does
not operate the properties, obtaining access to properties and records may be
more difficult.  Even when problems are identified, the seller may not be
willing or financially able to give contractual protection against such
problems and the Company may decide to assume environmental and other
liabilities in connection with acquired properties.  See "Business and
Properties--Oil and Gas Acreage."

   
         As is customary in the industry, the Company generally acquires oil
and gas acreage without any warranty of title except as to claims made by,
through or under the transferor.  Although the Company has title to developed
acreage examined prior to acquisition in those cases in which the economic
significance of the acreage justifies the cost, title opinions may not be
obtained if, in the Company's judgment, it would be
    





                                       41
<PAGE>   58
   
uneconomical or impractical to do so, and there can be no assurance that losses
will not result from title defects or from defects in the assignment of
leasehold rights.

         Additionally, significant acquisitions can change the nature of the
operations and business of the Company depending upon the character of the
acquired properties, which may be substantially different in operating and
geologic characteristics or geographic location from existing properties.
While the Company's current operations are located primarily in Texas, there is
no assurance that the Company will not pursue acquisitions or properties
located in other geographic areas.
    

   
    

FUTURE CAPITAL REQUIREMENTS

   
         The Company makes and will continue to make substantial capital
expenditures to further explore and develop its properties and to acquire
additional oil and gas properties.  These expenditures are currently
anticipated to be approximately $171.5 million for the second half of 1998.
Cash flow from operations will be used to fund these expenditures.  The Company
may also seek additional capital from traditional reserve base borrowings,
equity and debt offerings, joint ventures and other sources.  The Company's
ability to access additional capital will depend on its continued success in
exploring for and developing its reserves and the status of the capital markets
at the time such capital is sought.  In addition, the Company's ability to
obtain financing from existing or future partners in its drilling joint
ventures will depend on the continued cooperation of such partners, whose
interests may not be the same as those of the Company.  Accordingly, there can
be no assurance that capital will be available to the Company from any source
or that, if available, it will be on terms acceptable to the Company.  In such
an event, the development and exploration of the Company's properties could be
delayed and, accordingly, the implementation of the Company's business strategy
would be adversely affected.
    

UNCERTAINTY OF ESTIMATES OF RESERVES AND FUTURE NET REVENUES

   
         Estimates of the Company's proved developed oil and gas reserves and
future net revenues therefrom appearing elsewhere herein are based on reserve
reports audited by independent petroleum engineers.  The estimation of reserves
requires substantial judgment on the part of the petroleum engineers, resulting
in imprecise determinations, particularly with respect to new discoveries.
Estimates of proved undeveloped reserves, which comprise a significant portion
of the Company's total reserves, are by their nature less certain.  The
accuracy of any reserve estimate depends on the quality of available data as
well as engineering and geological interpretation and judgment.  Actual future
production, oil and gas prices, revenues, taxes, capital expenditures,
operating expenses, geologic success and quantities of recoverable oil and gas
reserves may vary substantially from those assumed in the estimates, may result
in revisions to such estimates and could materially affect the estimated
quantities and related PV-10 Value of reserves set forth in this Joint Proxy
Statement/Prospectus.  Although cost and reserve estimates attributable to the
Company's oil and gas reserves have been prepared in accordance with industry
standards, no assurance can be given that the estimated costs are accurate,
that development will occur as scheduled or that the results will be as
estimated.
    

         The present value of future net revenues referred to in this Joint
Proxy Statement/Prospectus should not be construed as the current market value
of the estimated oil and gas reserves attributable to the Company's properties.
In accordance with applicable requirements of the Commission, the estimated
discounted future net cash flows from proved reserves are generally based on
prices and costs as of the date of the estimate, whereas actual future prices
and costs may be materially higher or lower, except where changes in prices
were fixed under existing contracts.  There can be no assurance, however, that
such prices will be realized or that the estimated production volumes will be
produced during the periods indicated.  Future performance that





                                       42
<PAGE>   59
deviates significantly from the reserve reports could have a material adverse
effect on the Company.  See "Business and Properties--Properties" and "--Oil
and Gas Reserves."

OPERATING HAZARDS AND UNINSURED RISKS

         Hazards such as unusual or unexpected geologic formations, pressures,
downhole fires, mechanical failures, blowouts, cratering, explosions,
uncontrollable flow of oil, gas or well fluids, pollution and other
environmental risks such as oil spills, gas leaks, ruptures or discharges of
toxic gases are inherent in oil and gas exploration and production.  These
hazards could result in substantial losses to the Company due to injury and
loss of life, severe damage to and destruction of property and equipment,
pollution and other environmental damage and suspension of operations.  Because
the Company's drilling operations are conducted by independent contractors, the
Company does not have the benefit of workmen's compensation insurance for
liabilities arising out of the injuries to employees of such contractors.  The
Company carries insurance which it believes is in accordance with customary
industry practices, but, as is common in the oil and gas industry, the Company
does not fully insure against all risks associated with its business either
because such insurance is not available or because the cost thereof is
prohibitive.

EFFECT OF PRICE RISK MANAGEMENT

   
         The Company may, from time to time, enter into hedging transactions
with respect to a portion of its expected future production.  While such
transactions would be entered into with the objective of reducing risks
associated with price volatility, such transactions may limit potential gains
by the Company if oil and gas prices were to rise substantially over the price
established by a hedge.  In addition, such transactions may expose the Company
to the risk of financial loss in certain circumstances, including instances in
which (i) production is less than expected, (ii) there is a widening of price
differential between delivery points for the Company's production and the
delivery point assumed in the hedge arrangement, (iii) the counter parties to
the Company's futures contracts fail to perform on a contract or (iv) a sudden,
unexpected event materially impacts oil or gas prices.  See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."  To the extent that price floors
are purchased for a portion of the Company's production but are not needed, or
to the extent that future sales are made at prices below ultimate future market
prices, funds so spent will have been lost or income realized from sale of
production may be reduced.  See "Business and Properties--Price Risk
Management."
    

FOREIGN ACTIVITIES

   
         In the last five years, the Company has undertaken development and
exploration activities in New Zealand and Russia, and is also pursuing
opportunities in Venezuela.  The Company's investment in these projects was
approximately $15.1 million at December 31, 1997.  Russia has experienced and
continues to experience social, political and economic instability, and all of
the Company's operations overseas are subject to various additional risks,
including risks associated with foreign currency fluctuations, currency
controls, changes in laws (including laws regulating the import and export of
hydrocarbons) and political instability.  There can be no assurance that future
developments in these regions, over which the Company has no control, will not
impair the Company's operations in these regions or result in a loss of part or
all of the Company's investment.  See "--Leverage and Debt Service" and
"Business and Properties--Foreign Activities."
    





                                       43
<PAGE>   60
COMPETITION

         The Company operates in a highly competitive environment, competing
with major integrated and independent energy companies for customers, for the
acquisition of desirable oil and natural gas properties, as well as for the
equipment and labor required to develop and operate such properties.  Many of
these competitors have financial and other resources substantially greater than
those of the Company.  See "Business and Properties--Competition."

   
CONCENTRATION OF CREDIT

         The Company extends credit, primarily in the form of monthly oil and
gas sales and joint interest owners receivables, to various companies in the
oil and gas industry, which results in a concentration of credit risk.  The
concentration of credit risk may be affected by changes in economic or other
conditions and may accordingly impact the Company's overall credit risk.
During the year ended December 31, 1997, three oil or gas purchasers each
accounted for 10% or more of the Company's revenues, with those purchasers
together accounting for approximately 42% of revenues.  An economic downturn or
similar occurrence that affects such purchasers concurrently could prevent the
Company from collecting significant amounts of revenue owed to it by such
purchasers, and could thereby result in a material adverse effect on the
Company's financial condition and results of operations.
    

DEPENDENCE ON KEY PERSONNEL

         The Company depends, and will continue to depend in the foreseeable
future, on the services of its officers and key employees with extensive
experience and expertise in evaluating and analyzing producing oil and gas
properties and drilling prospects, maximizing production from oil and gas
properties and marketing oil and gas production.  The ability of the Company to
retain its officers and key employees is important to the continued success and
growth of the Company.  There can be no assurance that the Company will be
successful in retaining such employees, and the loss of key personnel could
have a material adverse effect on the Company.  See "Management."

GOVERNMENTAL AND ENVIRONMENTAL REGULATION

   
         The Company's operations are subject to regulation under a wide range
of foreign,  federal, state and local laws, rules, orders and regulations
relating to the development, production, marketing, transportation and storage
of crude oil and natural gas, protection of the environment and employee health
and safety.  In particular, such laws, rules and regulations govern air and
water emissions, the use, management and disposal of hazardous and
non-hazardous substances and wastes, and investigation and cleanup obligations
relating to contaminated properties.  Certain such laws and regulations require
well and facility sites to be closed and reclaimed in accordance with
requirements that may vary from one jurisdiction to another.  The Company
frequently buys and sells interests in properties that have been operated in
the past, and as a result of such transactions may have retained or assumed
cleanup or reclamation obligations relating to its own former operations or
those of third parties.  The Company is required to obtain and maintain
compliance with permits and other approvals for its drilling, reworking and
recompletion operations, for transporting hydrocarbons and other materials and
wastes, and for other aspects of its operations.  The various government
authorities that issue such permits may modify, renew or revoke them under
certain circumstances.  Failure to comply with requirements under its permits
or other applicable laws and regulations could subject the Company to
substantial civil or criminal penalties and to the temporary or permanent
curtailment or cessation of all or a portion of its operations.  Under certain
laws and regulations, the Company may also be subject to strict, joint
    





                                       44
<PAGE>   61
   
and several liability in connection with releases, or threatened releases, of
hazardous substances.  In addition, the Company may be subject to personal
injury or property damage claims relating to violations of environmental laws
and regulations, the cleanup of contaminated properties or reclamation of
former fields or exposure to hazardous substances.  The Company's costs of
maintaining compliance with its permit requirements and with other
environmental laws and regulations can be substantial, and there can be no
assurance that such requirements will not have a material adverse effect on the
Company's business results of operations and financial condition.
    

         Certain laws and regulations also require the Company to demonstrate
financial responsibility for drilling and operations, and impose various
reporting requirements.  In addition, most states in which the Company owns and
operates properties have regulations governing conservation matters, including
provisions for the unitization or pooling of oil and natural gas properties,
the establishment of maximum rates of production from oil and natural gas wells
and the regulation of the spacing, plugging and abandonment of wells.  Many
states also restrict production to the market demand for oil and natural gas
and several states have indicated interest in revising applicable regulations
in light of the persistent oversupply and low prices for oil and natural gas
production.  These regulations may limit the rate at which oil and natural gas
could otherwise be produced from the Company's properties. Some states have
also enacted statutes prescribing ceiling prices for natural gas sold within
the state.  The Company cannot predict how existing laws and regulations may be
interpreted by enforcement agencies or court rulings, whether additional laws
and regulations will be adopted, or the effect such changes may have on the
Company's business, results of operations or financial condition.  See
"Business and Properties--Regulations--Environmental Regulations."

   
    

YEAR 2000 ISSUE

   
         The Year 2000 issue results from computer programs written with date
fields that cannot distinguish between the year 1900 and 2000.  The Company is
currently studying the steps necessary to make the Company's operations Year
2000 compliant.  These steps include upgrading, testing and certifying its
computer systems and field operation services and obtaining Year 2000
compliance certification from all of the Company's important business
suppliers.  The Company does not believe that costs incurred to address the
Year 2000 issue with respect to its financial and administrative systems will
have a material effect on the Company.  The Company is uncertain, however, as
to the impact that the Year 2000 issue will have on its field operation systems
or as to how the Company will be indirectly affected by the impact that the
Year 2000 issue will have on the companies with which it conducts business.
For example, the pipeline operators to whom the Company sells gas, as well as
other customers and suppliers, could be prone to Year 2000 problems that could
not be assessed or detected by the Company.  In these cases, the effect of the
Year 2000 issue may be material.  See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Year 2000."

TAX RISKS

         The following is a discussion of the material federal income tax
consequences that are generally applicable under existing United States federal
income tax law to Investors that vote to liquidate the Partnership in which
such Investors are partners for federal income tax purposes and also for those
that elect to subscribe to shares of Company stock in lieu of receiving all or
some of their Partnership liquidating distribution.  The discussion is based
upon the Code, Treasury Regulations, judicial authority, published positions of
the Internal Revenue Service (the "Service") and other applicable authorities
(including to the extent applicable, certain private letter rulings, all as in
effect on the date hereof and all of which are subject to change, possibly
retroactively.  This discussion does not address all aspects of federal income
taxation that may be material or relevant to particular investors in light of
their own personal circumstances.  This discussion does not address any aspect
of state, local or foreign tax law or certain aspects of tax law solely
applicable to qualified plans and individual retirement accounts, all as
defined under the Code, and is not applicable 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 proceedings, or an
investment company, financial institution or insurance company.  No ruling has
been sought from the Service in connection with tax aspects related to the
proposed transactions.  Accordingly, no assurance can be given that the Service
will not take a position contrary to any of the tax aspects described below.
For a more complete discussion of the federal income tax consequences to
Investors in Partnerships that sell their properties and for those that elect
to subscribe to shares of Company stock see "Federal Income Tax Consequences of
the Proposals" and "Material Federal Income Tax Considerations of Electing to
Receive Common Stock in lieu of Cash Upon Partnership Liquidation."
Additionally, a summary discussion of the tax consequences upon the sale of
Partnership properties is contained in each supplement to this Proxy.  See
"Summary of Federal Income Tax Consequences."

INVESTORS THAT ARE TAX EXEMPT PLANS

         Investors that are Tax Exempt Plans that have directly or indirectly
acquired their Partnership interests through debt financing, as defined in the
Internal Revenue Code of 1986, as amended, or that have invested in
Partnerships that own interests in operating properties may be subject to
taxation on the Partnership's sale of property and the liquidation of the
Partnership.  See "Federal Income Tax Consequences of Adoption of the
Proposal--Tax Treatment of Tax Exempt Plans--Debt-Financed Property."  Tax
Exempt Plans, other than those described above, are not expected to be subject
to federal income tax on the sale of properties.

INVESTORS SUBJECT TO FEDERAL INCOME TAX

         Investors that are subject to federal income tax are expected to
recognize and realize taxable gain or loss, or a combination of both gain and
loss on the sale of Partnership property and the subsequent liquidation of the
Partnerships.  The character of the gain or loss depends on certain factors
specific to the Partnerships and to the Investors.  For a broader discussion of
the tax consequences, Investors should read "Federal Income Tax Consequences of
Adoption of the Proposal."

PAYMENT FOR STOCK WITH LIQUIDATING DISTRIBUTION

         Investors that subscribe for Company stock pursuant to this offering
will not actually receive some or all of the cash liquidating distribution of
their partnership interests to which they otherwise would be entitled.  The
amount of any cash liquidating distribution they actually receive depends upon
the purchase price to be paid for the shares they elect to and are entitled to
receive pursuant to the terms of this offering.  For federal





                                       46
<PAGE>   63
income tax purposes, Investors subscribing for shares of Company stock will be
treated as though they had purchased those shares for cash, even though they
never had actual possession of the cash used to acquire the shares.
Additionally, the fact that such Investors elect to acquire shares rather than
receive cash in liquidation of their partnership interests will not affect the
federal income tax consequences attending the liquidation of their partnership
interests.  Because the purchase of shares of Company stock will reduce the
cash received by the Investor on partnership liquidation, to the extent that
Investors owe federal income tax as a result of the liquidation, they may not
receive sufficient cash to pay some or all of any tax they may owe on the
liquidation.  Such Investors owing tax as a result of the liquidation will have
to pay such tax from sources other than distributions from their partnership.

                                SPECIAL FACTORS

BACKGROUND

         The Partnerships were formed between 1986 and 1994, with approximately
60% of the Partnerships having been in existence for over seven years.  As
contemplated when the Partnerships were organized, the hydrocarbon production
of the producing properties in which the Partnerships own interests have
steadily declined over time.  All of the Partnerships own interests in
properties with substantial natural gas reserves, and many of the Partnerships'
reserves are comprised almost totally of natural gas.  The general improvement
in the prices for natural gas over the last several years, relative to such
prices in the mid-1990's, make this an appropriate time, especially in light of
the age of the Partnerships, to consider Proposals to sell their Property
Interests.  For the reasons set out below, the Managing General Partner
believes that the Proposals under which it would purchase  all of the oil and
gas assets owned by the Partnerships are fair to Investors and are structured
in a manner that attempts to realize the highest value for each Partnership's
Property Interests, given that the purchase prices are based upon the higher of
two estimates on a Partnership-by-Partnership basis of the fair market value of
the Partnerships' Property Interests by three independent Appraisers to which
has been added a 7.5% premium.  The purchase of the oil and gas assets of any
particular Partnership is not conditioned upon the purchase of the oil and gas
assets of any Partnership other than a Partnership's companion Partnership.

PURPOSE AND EFFECT OF THE PROPOSALS

         By selling all of their respective oil and gas assets to the Managing
General Partner, proceeds from such liquidating sale will be distributed to the
partners in the Partnerships and the Partnerships will be liquidated, dissolved
and terminated.  These Proposals are subject to a number of conflicts of
interest, all of which are discussed in greater detail below.  The purpose of
the Proposals is to provide for the sale of the Partnerships' oil and gas
assets because it is time that the business of the Partnerships be concluded,
and to do so in a way intended to maximize the sale price of the Partnership's
oil and gas assets.  The Managing General Partner is proposing to purchase
these oil and gas assets from the Partnerships because it believes that its
knowledge of the Properties allows it to pay the highest price for such assets.
The reasons for proposing the sale of the Partnerships' Property Interests at
this time are described below under "Reasons for the Proposal--Reasons for Sale
of Assets at this Time."

         Approval of the Proposals will have the following effects:

1.       The Managing General Partner will purchase all of the oil and gas
         assets of each Partnership, and if applicable, its Companion
         Partnership which approve their respective Proposals;

2.       Such Partnerships, having sold all of their respective oil and gas
         assets, will be required to liquidate and distribute their assets
         (principally the cash proceeds from sale of their Property Interests)
         to their partners (including the general partners) in accordance with
         their respective ownership interests in the Partnerships;

3.       Investors will be given the option of receiving shares of Common Stock
         in amounts that they choose on an individual basis in lieu of some or
         all of the cash they would be entitled to receive upon their
         Partnerships' liquidation, as discussed in detail below under
         "Investor Election to Participate in Offering of 2,500,000 shares of
         Common Stock to Eligible Purchasers";





                                       48
<PAGE>   65
4.       The Managing General Partner intends to spend capital needed to
         develop non-producing reserves on certain of the Partnerships'
         Property Interests which it acquires, although the properties in which
         such investment will be made have not yet been determined; and

5.       Investors in the Partnerships will be taxed on the sale of their
         Partnerships' oil and gas assets, which will result in a gain or a
         loss depending upon the particular Partnership in which an Investor
         has an ownership interest, and dependent upon the individual tax
         status of that Investor.

PARTNERSHIP PROPERTY INTERESTS

         Tabulations presenting information specific to a Partnership are set
out in each Partnership's specific Partnership Supplement on those fields in
which such Partnership has Property Interests which constitute 10% or more of
the Partnership's PV-10 Value at December 31, 1997.  A Partnership's "PV-10
Value" is the estimated future net cash flows (using unescalated prices) from
production of proved reserves attributed to such Partnership's Property
Interests, discounted to present value at 10% per annum (See "Glossary of
Terms").  The information set forth in the Partnership Supplement includes the
location of each field, the number of wells and operators, together with
information on the percentage of the Partnership's total PV-10 Value on
December 31, 1997, attributable to each of these fields.  Information is also
provided regarding such percentage of the Partnership's 1997 production (on a
volumetric basis) from each of these fields.

REASONS FOR THE PROPOSALS

         THE REASONS FOR PROPOSING THE SALE OF THE PARTNERSHIP'S PROPERTY
INTERESTS AT THIS TIME ARE DESCRIBED IN DETAIL FOR EACH PARTNERSHIP IN THAT
PARTNERSHIP'S SUPPLEMENT INCLUDED WITH THIS JOINT PROXY STATEMENT/PROSPECTUS
UNDER "SPECIAL FACTORS--REASONS FOR THE PROPOSAL," AND VARY FROM PARTNERSHIP TO
PARTNERSHIP DEPENDING UPON, AMONG OTHER FACTORS, A PARTNERSHIP'S AGE AND THE
NATURE OF PROPERTY INTERESTS WHICH IT OWNS.  The Managing General Partner
believes that it is in the best interest of the Investors for their
Partnerships to sell their Property Interests at this time and to dissolve the
Partnerships and make a final liquidating distribution to its Partners for the
reasons discussed below.  Certain reasons are common to all Partnerships.
Other reasons vary from Partnership to Partnership and are highlighted below.

         Current Liquidating Distribution Lowers Volatility Risk

         The Partnerships have been in existence for between four and twelve
years.  The Managing General Partner believes that the ability to receive the
estimated liquidating distribution in one lump sum currently, rather than
smaller amounts over a longer period, is one of the benefits of the Proposals,
without the risk of such distributions being negatively affected by oil and gas
price changes.  Receiving the value of the Partnerships' assets at one time
avoids the risk of subjecting future revenues and cash distributions of
Investors to the continued and extreme volatility of oil and gas prices, as
well as inherent geological, engineering and operational risks, which could
affect future returns.  It is also the Managing General Partner's belief that
improvements over the last several years in the level of natural gas prices,
relative to such prices in the mid-1990's, make this an appropriate time to
consider the sale of the Partnerships' Property Interests and increases the
likelihood of maximizing the value of the Partnerships' assets, although the
future prices and market volatility cannot be predicted with any accuracy.





                                       49
<PAGE>   66
         Decreasing Cash Flow While Expenses Continue

         Although the amount differs among Partnerships, other than as to the
16 Partnerships formed in 1993 and 1994 a majority of the estimated ultimate
recoverable reserves in which the Partnerships have an interest have been
produced.  As a result of the depletion of the Partnerships' oil and gas
reserves, the Managing General Partner believes the asset base and future net
revenues of the Partnerships formed between 1986 and 1992 no longer justify the
continuation of operations.  The Partnership's underlying interests in oil and
gas reserves are expected to continue to decline as remaining reserves are
produced.  Declines in well production are based principally upon the maturity
of the wells, not on market factors.  These declines will occur while operating
costs and general and administrative expenses continue, which are relatively
fixed amounts.  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.  By
accelerating the liquidation of the Partnership, those future administrative
costs will be avoided by the Partnerships.

   
         Effect of Oil and Gas Prices on Value

         The Managing General Partner believes that the key factor affecting
the Partnerships' long-term performance has been the decrease in oil and
particularly gas prices that occurred subsequent to the purchase of Partnership
Property Interests.  Additionally, prices are expected to continue to vary
widely over the remaining life of the Partnerships, and such changes in prices
will affect future estimates of revenues from continued operations of the
Partnerships, especially for the 39 Partnerships with less than a third of
their estimated remaining recoverable reserves remaining for future production
(all but two of the Partnerships formed prior to the second quarter of 1992).
Many Partnerships have only a small amount of their ultimate recoverable
reserves remaining for future production.  Because of small amounts of
remaining reserves, even if oil and gas prices were to increase in the future,
such increases would be unlikely to have a material positive impact on the
total return on investment to Investors in view of the expenses of the
Partnerships as described above.
    

         Non-Producing Reserves

         For those 18 Partnerships formed in the fourth quarter of 1986, in the
first three quarters of 1987, and in the period from the fourth quarter of 1992
through the second quarter of 1994, a majority of the estimated remaining
recoverable reserves attributable to those Partnerships' Property Interests are
proved non-producing reserves.  Non- producing reserves generally fall into two
categories:  (1) undeveloped reserves, which require substantial expenditures
by the working interest owners for the drilling of new wells to recover such
reserves; and (2) behind-pipe reserves, which are unlikely to be producible for
many years because behind-pipe reserves require completion in a different
producing zone, which does not take place until production is depleted from the
currently producing zone.  Recovery in amounts great enough to significantly
impact the results of those Partnerships' operations and their ultimate cash
distributions can only occur after currently producing zones are depleted in
many years, or with the investment of new capital.  As provided in the
Partnership Agreements, the Partnerships expended all of the Investors' net
commitments for the acquisition of Property Interests many years ago, and they
no longer have capital to invest in improvement of the properties through
secondary or tertiary recovery.

         The most important factor leading to the significant proportion of
behind-pipe or undeveloped reserves currently owned by the Partnerships has
been the depletion of most of the Partnerships' proved producing





                                       50
<PAGE>   67
reserves, resulting in the growth over time in the proportion of the
Partnerships' total assets comprised of non- producing reserves.  Thus,
non-producing reserves which were a small proportion of each Partnership's
reserves when its oil and gas assets were purchased have remained and grown to
comprise a larger proportion of the Partnerships' remaining assets.

         A limited amount (less than 10%) of the capital of the Operating
Partnerships was reserved for workover, completion or development activity, the
Partnerships were not intended to engage in material drilling activities.  The
Partnerships were formed to distribute cash from sale of Partnership's oil and
gas production to Investors on a current basis.  The current level of cash flow
of the Partnerships is not sufficient to pay for meaningful drilling activities
or to support borrowing activities for that purpose.  Even if cash flow were
allowed to be used for drilling by a Partnership's limited partnership
agreement, this would require suspension of cash distributions for an extended
period.

         Reasons for Sale of Assets at this Time

   
         The Managing General Partner believes that this is an appropriate time
for the Partnerships to sell their Property Interests due to its perception of
the marketplace, including estimates as to future oil and gas prices, the cash
flow of the Partnerships and the character of their reserves.  The Managing
General Partner believes that after significantly depleting producing oil and
gas properties, they become less attractive to prospective purchasers because
of less cash flow.  Additionally, the Partnerships' limitations on capital
invested in drilling activities in recent years also makes the Property
Interests less attractive to prospective purchasers.  Although the price of oil
has fallen significantly in 1998, gas prices have declined but to a lesser
degree.  Given the fact that the reserves of the Partnership Properties and
their recent production consist principally of gas, this is believed to be a
good time to sell the Partnership Properties to avoid the risk that gas prices
might fall to levels equivalent to those for oil.  At the current time the
marketplace's perception is  that gas prices are likely to increase.  Based
upon its experience in the industry and past historical trends, the Managing
General Partner believes that it is often preferable to sell based upon
perceptions of future prices.  Moreover, the sale at this time by any
Partnership in conjunction with the other 62 Partnerships to whom Proposals
have been made allows the costs of the transactions to be spread among a larger
number of entities, which costs are likely to be much higher if such asset
sales were made on an individual Partnership basis or by small groups of
Partnerships over an extended period of time.
    

         Investors' Tax Reporting

         Investors will continue to have a partnership income tax reporting
obligation with respect to his Units as long as the Partnerships continue to
exist.  There is no trading market for the Units, so Investors generally are
unable to dispose of their Units.  See "Business of the Partnership--No Trading
Market."  Following the approval of the Proposal and the sale of the
Partnerships' Property Interests and dissolution of the Partnerships, Investors
will realize gain or loss, or a combination of both, under federal income tax
laws.  Thereafter, Investors will have no further tax reporting obligations
with respect to the Partnerships.  The dissolution of the Partnerships will
also allow certain Investors to take a capital loss deduction for syndication
costs incurred in connection with formation of their Partnerships.   See
"Federal Income Tax Consequences of Adoption of the Proposal."

INDEPENDENT APPRAISAL OF THE FAIR MARKET VALUE OF PROPERTY INTERESTS OF THE
PARTNERSHIPS

         The Special Transactions Committee selected H.J. Gruy and Associates,
Inc. ("H.J. Gruy" or "Gruy"), J.R. Butler and Company ("J.R. Butler" or
"Butler") and CIBC Oppenheimer Corp. ("CIBC Oppenheimer")





                                       51
<PAGE>   68
to estimate the fair market value of the Property Interests of each of the
Partnerships.  Collectively, H.J. Gruy, J.R.  Butler and CIBC Oppenheimer are
referred to herein as the "Appraisers," and H.J. Gruy and J.R. Butler together
are sometimes referred to herein as the "Petroleum Engineering Consultants."

         The Special Transactions Committee determined that having three
independent appraisers collectively determine the fair market value for a cash
purchase of the Partnerships' Property Interests would protect Investors by
attempting to address the conflicts of interest in the sale of such Property
Interests to the Managing General Partner.  The Appraisers were selected based
upon the Special Transactions Committee's assessment of their professional
reputations and qualifications, capabilities, experience and responsiveness.
The Special Transactions Committee believes that using the three Appraisers
working collectively provides the distinct professional expertise of each firm,
and gives the Partnerships the benefit of the independent analytic methods of
the different disciplines of petroleum engineering and investment banking,
resulting in a determination of fair market value which is both independent and
comprehensive.

         One of the three Appraisers, H.J. Gruy, is the independent petroleum
engineering firm most familiar with the properties in which the Partnerships
have interests and has prepared the annual reserves audit and independent
reserve report upon the Partnerships' reserves since inception of each of the
Partnerships.  J.R. Butler and H.J. Gruy together are actively involved as a
principal part of their businesses in the evaluation of producing oil and gas
properties, and both are widely recognized in their field.  The Petroleum
Engineering Consultants are independent consulting firms as provided in the
Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves
Information promulgated by the Society of Petroleum Engineers ("SPE").  As an
internationally known investment banking firm with broad experience in the oil
and gas industry, CIBC Oppenheimer has used additional methods of analysis and
considered other factors and perspectives in evaluating the Partnerships'
Property Interests.

         The Managing General Partner did not instruct the Appraisers as to
pricing, cost or other economic parameters or methods or the assessment of
reserves characteristics, nor did it limit the scope of their investigation for
purposes of preparing their appraisals.  The Managing General Partner provided
the Petroleum Engineering Consultants with basic evaluation data for their use
in determining each Partnership's reserves and their value.  The Petroleum
Engineering Consultants prepared their own reserves audit of the Property
Interests.  The Managing General Partner did not set the amount of
consideration to be paid to the Partnerships for their Property Interests nor
provide any information to the Appraisers on amounts to be paid to the
Investors.  The amount of consideration to be paid was determined by the
Special Transactions Committee based upon the Appraisers' assessment of the
fair market value of those interests.  The Appraisers did not opine on the
fairness of the transaction to the Investors, and the Managing General Partner
has not acquired separate reports or opinions regarding the fairness to the
Investors of the prices at which the Partnerships' Property Interests will be
sold to the Managing General Partner if the Proposals are approved by the
Investors.

         J.R. Butler is an established worldwide oil and gas consulting firm
organized in 1948 by Mr. J.R. Butler, Sr.  and has been headquartered in
Houston, Texas since its founding.  J.R. Butler has extensive experience in
reserves estimation, property evaluation, formation evaluation, petrophysical
support for geophysical and exploration geology, drilling operations,
production surveillance, unitization and design and supervision of workovers.
Over the last 20 years Butler has performed projects for more than 350 clients,
which include law firms, financial institutions, oil and gas operators,
research/academic institutions, service companies, individual investors and
government bodies, and has been involved with more than 140 major consulting
projects involving evaluation of U.S. oil and gas properties.  Approximately
50% of Butler's work in 1997 was devoted to property evaluations.  Butler
administered and analyzed the annual "Evaluation Parameters Survey" for the
Society of Petroleum Evaluation Engineers ("SPEE") during the first 15 years of
its publication from 1982 to 1996.

         CIBC Oppenheimer, a CIBC World Markets Company, is an internationally
recognized investment banking firm with 31 offices worldwide and over 8,000
employees. CIBC Oppenheimer was selected by the Special Transactions Committee
to serve with the Petroleum Engineering Consultants as an appraiser based upon
CIBC Oppenheimer's substantial experience in oil and gas property purchase and
sale transactions, familiarity with the Managing General Partner, and
familiarity with oil and gas company operations and the oil and gas industry in
general.  CIBC Oppenheimer regularly engages in the valuation of oil and gas
businesses and their securities in connection with mergers and acquisitions,
negotiated underwritings, private placements and other corporate purposes.

FAIR MARKET VALUE

         For each Partnership, the Petroleum Engineering Consultants estimated
the aggregate fair market value of each Partnership's Property Interests as of
December 31, 1997.  CIBC Oppenheimer also estimated a fair market value of the
same Property Interests at the same date.  For each Partnership, the Special
Transactions Committee chose the higher of these two determinations as the Fair
Market Value for the purchase of these interests and the Board of Directors of
the Company determined to pay a 7.5% premium above the fair market value to
purchase the Partnerships' Property Interests.  The valuation estimates of the
Appraisers are attached to specific Partnership's Supplement.  The PV-10 Value
for each Partnership prepared on an annual basis by H.J. Gruy of the same
Property Interests as of the same date is also set out in the specific
Partnership's Supplement.  The valuations of the Appraisers do not in any
manner address the underlying business decision to sell these Property
Interests.  Moreover, the valuation estimates of the Appraisers are necessarily
based upon the market, economic and other conditions as they existed on the
dates specified or could be evaluated as of the date of preparation of the
valuations.

         The Petroleum Engineering Consultants arrived at a fair market
valuation estimate, which is discussed in detail under "--Valuation by
Petroleum Engineering Consultants" below and is based upon appraisal of the
projected discounted cash flow from the various Property Interests.  On the
other hand, the investment banking firm of CIBC Oppenheimer made a valuation
estimate for each Partnership based upon the application of multiple
quantitative and qualitative factors.  The quantitative factors include, among
other things, a review of relevant valuation criteria from comparable
acquisitions of both oil and gas properties and companies which are
predominantly active in the oil and gas industry, and a review of valuation
criteria for relevant publicly traded oil and gas companies.

         Although CIBC Oppenheimer was not directly involved in the work
performed by the Petroleum  Consultants, it did review both the methodology
employed and the resulting analysis from the application of the approach used
by the Petroleum Engineering Consultants.  In turn, although the Petroleum
Engineering





                                       53
<PAGE>   70
Consultants were not directly involved in the evaluation work performed by CIBC
Oppenheimer, they provided input to, and consulted with, CIBC Oppenheimer as to
the characteristics of certain groups of Property Interests.  As a result of
their individual and collective work, the Petroleum Engineering Consultants
estimated a fair market valuation for groups of properties that are related
geographically, geologically or by time of acquisition by the Partnerships (a
"Partnership Group") in which the Partnerships have Property Interests,  and
CIBC Oppenheimer estimated a fair market valuation for each such property
group.  These valuation amounts were then divided among the Partnerships which
own Property Interests in each property group in proportion to their respective
ownership interests therein.  This generated valuation estimates for each
Partnership.  After presentation of the two valuation estimates for each
Partnership to the Special Transactions Committee, the committee determined
that the Fair Market Value for each Partnership was the higher of the two
values estimated by the Petroleum Engineering Consultants and CIBC Oppenheimer.
This necessarily matches the definition of "Fair Market Value," which is the
maximum price that a willing buyer will pay and at which a willing seller will
sell at a given point in time at which the buyer is under no compulsion to buy
and the seller is not compelled to sell, both having reasonable knowledge of
all the material circumstances.

VALUATION BY PETROLEUM ENGINEERING CONSULTANTS

         The value estimate from the Petroleum Engineering Consultants uses the
"income approach."  The income approach for proved producing properties reduces
the discounted future net cash flows before federal income tax to a fair market
value by multiplying such cash flow by a suitable fraction that accounts for
the risk associated with the purchase of that cash flow stream.  For proved
developed non-producing and proved undeveloped reserves, the risk adjustments
are generally more severe for a variety of reasons, including the necessity of
making a capital investment when it is assumed that the capital is invested
with certainty and the resulting operating cash income stream is burdened with
the uncertainty.

         The Petroleum Engineering Consultants audited the estimates of proved,
probable and possible reserves and future net revenues therefrom prepared by
the Managing General Partner utilizing standard petroleum engineering methods.
For properties with sufficient production history, reserves estimates and rate
projections were based primarily on extrapolation of established performance
trends and reconciled, whenever possible, with volumetric and/or material
balance calculations.  For the undeveloped locations, reserves were determined
by a combination of volumetric calculations (geologic mapping) and analogy.
Volumetrically determined reserves or those determined by analogy are generally
subject to greater qualifications than reserve estimates supported by
established production decline curves and/or material balance calculations.
The Petroleum Engineering Consultants audited the determination and
classification of proved reserves in accordance with Securities and Exchange
Commission guidelines (with the exception of having employed escalated prices
and costs).  The definitions used by the Petroleum Engineering Consultants for
the unproved reserves conform to those promulgated by the Society of Petroleum
Engineers, Inc. (SPE) and the World Petroleum Congresses (WPC).

         Basic evaluation data used by the Petroleum Engineering Consultants,
including ownership and other data, logs, maps, production data, tests,
technical information, estimates of drilling, completion and workover costs and
operating costs, were obtained principally from the Managing General Partner.
Benchmark gas and oil prices were $2.38 per MMBtu and $16.00 per barrel for
West Texas Intermediate, respectively, which were based upon year-end 1997
prices (before adjustments for Btu content for gas and gravity variances for
oil as well as transportation charges and geographic location) and then
escalated at a rate of 3.5% per annum for a period of 15 years.  Operating
costs and projected investments were also escalated at the rate of 3.5% per
year for 15 years.  The Petroleum Engineering Consultants recommended this
escalation scenario based on rates being used by banks, oil and gas industry
sources, the U.S.  government and other oil and gas companies which





                                       54
<PAGE>   71
acquire producing properties.  The estimates of future net cash flow consisted
of those revenues expected to be realized from the sale of the estimated
reserves after deduction of royalties, ad valorem and production taxes, direct
operating costs, excess costs and required capital expenditures, when
applicable.  Future net cash flow was determined before the deduction of
federal income tax.  The Petroleum Engineering Consultants prepared their value
estimates by applying qualitative risk adjustments considered by them to be
appropriate for the various reserves categories against the spread of
discounted future net cash flow values obtained from an escalated pricing
scenario.

         The reserves and the resulting "value estimates" made by the Petroleum
Engineering Consultants are not exact quantities.  Future conditions may affect
the recovery of estimated reserves and revenue, and all categories of reserves
may be subject to revision and/or reclassification as more performance and well
data become available.  Furthermore, any oil or gas reserves estimate or
forecast of production and income is a function of engineering and geological
interpretation and judgment and such estimates should be used with the
understanding that additional information obtained subsequent to a study may
justify revisions which could increase or decrease the original estimates of
reserves and value.

         In summary, the evaluation procedures used by the Petroleum
Engineering Consultants included:

         o       Reviewing technical and economic data presented by the
                 Managing General Partner relative to proved, probable and
                 possible reserves as of December 31, 1997.

         o       Examining the cash flow forecasts for individual wells and/or
                 production units for their quantified probable and possible
                 reserves.

         o       Reviewing the lease operating costs for individual wells
                 and/or production units for reasonableness.

         o       Preparing reserves and future performance estimates for the
                 audit evaluation utilizing standard petroleum engineering
                 methods.  For wells and/or production units with sufficient
                 production history, reserves estimates and rate projections
                 were based primarily on extrapolation of established
                 performance trends.  For the non-producing zones and
                 undeveloped locations, reserves were determined by a
                 combination of volumetric calculations and analogy.

         o       Estimating of drilling, completion and workover costs, which
                 was based on information supplied by the Managing General
                 Partner.  Surface and well equipment salvage values and well
                 plugging and field abandonment costs were not considered in
                 the cash flow projections.

         In performing its analysis of the value of each Partnership's Property
Interests, CIBC Oppenheimer first reviewed the PV-10 Value at December 31, 1997
for each property group in which such Partnership has a Property Interest (a
"Property"). In addition, CIBC Oppenheimer reviewed the valuation estimates
prepared by the Petroleum Engineering Consultants for each Property.
Individual Partnerships own interests in a number of different Properties.
Therefore, CIBC Oppenheimer first focused upon valuing the individual
Properties and then subsequently valuing the Property Interests of each
Partnership in various Properties by allocating to each Partnership its
relevant share of the value attributable to different Properties in which it
has an interest.





                                       55
<PAGE>   72
         Working with the Petroleum Engineering Consultants, CIBC Oppenheimer
reviewed the Properties for characteristics which would allow them to be
divided into separate classifications.  Of the total of 44 Properties, the
reserves of 34 Properties were determined to be comprised primarily of Proved
Developed Producing reserves ("PDP") which have comparable reserve
characteristics ("Conventional Case").  The remaining 10 Properties were
determined to have distinguishing or unique reserves characteristics in that
their reserves are comprised predominately of reserves in the Proved Developed
but Not Producing ("PDNP") and Proved but Undeveloped "(PUD") categories
(collectively, the "Non- Conventional Case").

         The individual Properties in the Conventional Case group and the
Non-Conventional Case group were valued according to the following three
criteria (collectively and individually, the "Valuation Multiples"): value as a
percentage of PV-10 Value; value as a multiple of barrels of oil equivalent on
a revenue interest basis ("BOE")  (See "Glossary of Terms"); and value as a
multiple of projected earnings before interest, taxes and depreciation,
depletion and amortization ("EBITDA") for 1998.

         The Valuation Multiples were, in turn, developed from the application
of multiple quantitative and qualitative factors.  The quantitative factors
include a review of relevant valuation criteria from comparable acquisitions of
both oil and gas properties and companies which are predominantly active in the
oil and gas industry, and a review of valuation criteria for relevant publicly
traded oil and gas companies (the "Analysis Factors").

         The Valuation Multiples determined for the Properties in the
Conventional Case group and the Non-Conventional Case group were unique,
reflecting the different reserves characteristics of the two groups.  Based
upon conversations with the Petroleum Engineering Consultants, CIBC Oppenheimer
applied a 20% adjustment factor to the Valuation Multiples used in the
Conventional Case in order to determine Valuation Multiples applied to the
Non-Conventional Case.  The adjustment factor was applied to the
Non-Conventional Case because PDNP and PUD reserves are less valuable than PDP
reserves, and PDNP and PUD reserves have additional costs and risks involved in
bringing known reserves into production.  Also associated with these types of
reserves are uncertainties as to the estimated quantities of oil and gas
included in such reserves and in the timing of first production and initial
production rates once such reserves are placed into production.

         CIBC Oppenheimer applied its set of Valuation Multiples to a
mathematical model, with each valuation multiple given equal weight (e.g.,
33.3% each) to compute a weighted average value for each individual Property.
Each Partnership was allotted its respective proportionate share of individual
Properties ("Property  Share") based upon the Partnership's Property Interest
in such Property in order to convert the value determined for the Properties
into values for an individual Partnership's Property Interests in each
Property.  The CIBC Oppenheimer valuation estimate for each individual
Partnership is the cumulative total of that Partnership's respective Property
Shares.

         Analysis Factors

         Analysis of Relevant Publicly Traded Companies.  Using publicly
available information, CIBC Oppenheimer compared selected projected operating
and financial data and ratios of the Managing General Partner to the
corresponding data and ratios of certain publicly traded oil and gas companies
considered by CIBC Oppenheimer to be reasonably comparable to the Managing
General Partner due to their focus primarily on exploring and developing oil
and gas reserves in the Mid-Continent and onshore Gulf Coast regions of the
U.S. and their similar business strategies, operations and market capabilities
(the "Selected Companies").  The Selected Companies consist of Abraxas
Petroleum, Bellwether Exploration, Comstock Resources, Cross Timbers Oil,
Gothic Energy, National Energy Group, Titan Exploration and Wiser Oil Company.

<PAGE>   73
         Analysis of Comparable Property Acquisitions.  CIBC Oppenheimer
reviewed publicly available information relating to certain acquisitions of
U.S. oil and gas companies that closed between March 10, 1994 and October 23,
1997, and had total transactions values between $20 million and $150 million.
These transactions consisted of 10 transactions in many of the same operating
regions in which the Partnerships own Property Interests and included the
following: Comstock Resources and Black Stone Oil; National Energy and
Alexander Energy; Alliance Resources and LaTex Resources; Melrose Petroleum
Group and Pentex Energy; PANACO and Goldking Companies; Alexander Energy and
American Natural Resources; Gothic Energy and Buttonwood Energy; Key Production
and Brock Exploration; ONEOK and PSEC; and ONEOK and Washita Production.  These
selected transactions are not intended to represent the complete list of oil
and gas transactions which have occurred or been announced during this period;
rather, such transactions represent recent transactions involving publicly
traded oil and gas companies engaged in oil and gas exploration and production
activities that were deemed by CIBC Oppenheimer to operate in comparable
producing basins or have comparable financial and operating characteristics to
the Managing General Partner.

         No company or transaction described above was directly comparable to
the Partnerships, their reserves, the Managing General Partner or the proposed
transaction.  Accordingly, analysis of the results of the foregoing was not
simply mathematical or necessarily precise; rather, it involved complex
considerations and judgments concerning differences in financial and operating
characteristics of companies and other factors that could affect public trading
values.

         Analysis of Comparable Reserve Acquisitions.  CIBC Oppenheimer
reviewed selected acquisitions of oil and gas reserves from January 24, 1995 to
December 18, 1997, with aggregate purchase prices up to $150 million.  The
selected acquisitions were in comparable geographic regions as the
Partnerships' Property Interests and these were reviewed for the consideration
paid in such transactions in terms of the aggregate purchase price paid as a
multiple of the reported total proved reserves on a BOE basis.  This analysis
relies primarily on information obtained from John S. Herold, Inc.  and may not
represent the complete list of oil and gas transactions with the given search
parameters that have occurred or been announced.

         Valuation Multiples

         Value as a Percentage of PV-10.  CIBC Oppenheimer's analysis included,
among other things, the consideration of a company's market capitalization of
common stock as of April 7, 1998 plus total debt and preferred stock, less cash
and cash equivalents ("Aggregate Value") as a multiple of the Company's PV-10
Value as of the most recently reported date.  Given the difficulty of
identifying truly comparable companies to the Managing General Partner which
are at the same stage of reserve exploration and development and have similar
financial and technical resources, none of the Selected Companies are identical
to the Managing General Partner.  In addition, the Properties which comprise
the Non- Conventional Case are comprised predominately of PDNP and PUD reserves
which tend to be inherently difficult to analyze, given the significant impact
which future development capital could have relative to existing operations.
CIBC Oppenheimer applied its reference value of 78% to the Property's PV-10
Value.  This reference value reflects a slight discount to the adjusted average
value at which comparable properties are acquired.  This discount reflects (i)
the fact that the Managing General Partner itself trades at a discount to the
adjusted average value of its peers on a PV-10 Value basis, and (ii) that
certain oil and gas properties in the Properties are generally near the end of
their economic lives and require additional capital investment to attain
sustained and/or enhanced production.  In the Non-Conventional Case, CIBC
Oppenheimer applied an adjustment factor of 20% to its reference value to
reflect higher proportions of PDNP and PUD reserves, an approach that is
consistent with conversations held between CIBC Oppenheimer and the Petroleum
Engineering Consultants.





                                       57
<PAGE>   74
         Value as a Multiple of BOE.  CIBC Oppenheimer reviewed the
consideration paid in such transactions in terms of the price paid for the
common stock plus total debt, preferred stock and transaction costs less cash
and cash equivalents of such transactions as a multiple of the reported total
proved reserves on a BOE basis.  Using comparable company acquisitions data,
the analysis of purchase price as a multiple of proved reserves on a BOE basis
indicated an adjusted average value of $4.90 per BOE for acquisitions of
comparable onshore Gulf Coast and Mid-Continent oil and gas companies while
comparable onshore Gulf Coast and Mid-Continent oil and gas properties were
acquired for $4.83 per BOE.  Relative to other acquisition values, CIBC
Oppenheimer applied a $4.70 per BOE reference value, which represents a slight
discount to the aforementioned acquisition values, to reflect the fact that
certain individual properties in the Properties are near the end of their
economic lives. The degree of this discount was reduced, however, by the fact
that the Properties exhibit an above average gas reserve component.  In the
Non-Conventional Case, CIBC Oppenheimer applied an adjustment factor of 20% to
its reference value to reflect higher proportions of PDNP and PUD reserves, an
approach that is consistent with conversations held between CIBC Oppenheimer
and the Petroleum Engineering Consultants.

         Value as a Multiple of EBITDA.  CIBC Oppenheimer's analysis included,
among other things, Aggregate Value as a multiple of projected EBITDA.
Projected EBITDA for the Managing General Partner and the Selected Companies
were based on estimates compiled by Institutional Brokers Estimate Service and
published estimates of selected investment banking firms, including CIBC
Oppenheimer.

         CIBC Oppenheimer's reference value of 3.5x is slightly lower than the
trading value of the Managing General Partner relative to its projected 1998
EBITDA.  This value is used to reflect the fact that certain oil and gas assets
in the Properties require significant additional capital investment to extend
their productive lives.  In the Non- Conventional Case, CIBC Oppenheimer
applied an adjustment factor of 20% to its reference value to reflect higher
proportions of PDNP and PUD reserves, an approach that is consistent with
conversations held between CIBC Oppenheimer and the Petroleum Engineering
Consultants.

         No company or transaction used in the analysis described above was
directly comparable to the Properties, the Managing General Partner or the
proposed transaction.  Accordingly, analysis of the results of the foregoing
was not simply mathematical nor necessarily precise; rather, it involved
complex consideration and judgments concerning differences in financial and
operating characteristics of companies and other factors that could affect
public trading values.

         Valuation Letters of CIBC Oppenheimer

         The Special Transactions Committee retained CIBC Oppenheimer to
prepare for each of the Partnerships an independent fair market valuation of
the Property Interests held by the Partnerships.  On April 20, 1998, CIBC
Oppenheimer delivered to the Special Transactions Committee letters for each of
the Partnerships (the "Valuation Letters") stating that, as of a certain date
and based upon and subject to the factors and assumptions set forth therein,
CIBC Oppenheimer's estimate of the value of the Partnership's Property
Interests.  The appraisal report of CIBC Oppenheimer will be available to
Investors or representatives designated in writing for inspection and copying
during the solicitation period for the Proposals at the office of the Managing
General Partners, 16825 Northchase, Suite 400, Houston, Texas 77060 from 9:00
a.m. to 5:00 p.m. Monday to Friday during such period.

         The full text of each of the Valuation Letters, which sets forth the
assumptions made, matters considered, and qualifications and limitations on the
review undertaken by CIBC Oppenheimer, is attached to the specific
Partnership's Supplement and is incorporated herein by reference.  The summary
of the





                                       58
<PAGE>   75
Valuation Letters set forth in this Joint Proxy Statement/Prospectus is
qualified in its entirety by reference to the full text of such letters.
Investors of the Partnerships are urged to read such letters in their entirety.
The Valuation Letters were provided to the Special Transactions Committee for
its information and is directed only to the estimates, from a financial point
of view, of the value of the Partnerships' Property Interests and does not
address the merits of the underlying decision by the Managing General Partner
or the Partnerships to engage in the sale of the Property Interests to the
Managing General Partner and does not constitute a recommendation to the
Partnerships' Investors as to how such Investors should vote on the approval of
the Proposals or any matter related thereto.

         The summary set forth above does not purport to be a complete
description of the analyses performed by CIBC Oppenheimer.  The fair market
value estimates involve various determinations as to the most appropriate and
relevant methods of financial analysis and the application of these methods to
the particular circumstances and, therefore, such estimates are not readily
susceptible to summary description.  These estimations of fair market value
required CIBC Oppenheimer to exercise its professional judgment based on its
experience and expertise in considering a wide variety of analyses taken as a
whole.  Each of the analyses conducted by CIBC Oppenheimer was carried out in
order to provide a different perspective on the transaction and add to the
total mix of information available.  CIBC Oppenheimer did not form a conclusion
as to whether any individual analysis, considered in isolation, supported or
failed to support any one valuation methodology.  Rather, in reaching its
conclusion, CIBC Oppenheimer considered the results of the analyses in light of
each other and ultimately reached its value estimate based on the results of
all analyses taken as a whole.  Except as described herein, CIBC Oppenheimer
did not place particular reliance or weight on any individual analysis, but
instead concluded that its analysis, taken as a whole and that selecting
portions of its analyses and the factors considered by it, without considering
all analyses and factors, may create an incomplete view of the evaluation
process underlying its value estimate.  In performing its analyses, CIBC
Oppenheimer made numerous assumptions with respect to industry performances,
business and economic conditions and other matters.  The analyses performed by
CIBC Oppenheimer are not necessarily indicative of actual values or future
results, which may be significantly more or less favorable than suggested by
such analysis.

COLLECTIVE ANALYSIS OF PURCHASE PRICE

         Thus, as described above, the Petroleum Engineering Consultants
individually audited the estimate of present value of future net cash flows
from the 44 property groups in which Property Interests are owned by the
Partnerships to whom similar proposals are being made to sell substantially all
of their assets and liquidate their Partnerships.  The Petroleum Engineering
Consultants began their analysis based upon the year-end 1997 PV-10 Value of
each property audited by H.J. Gruy and together they re-evaluated reserve
quantities, projected operating costs and cash flows.  The present value of
this reserves analysis was then derived by escalating year-end 1997 prices
($2.38 per MMBtu and $16.00 per barrel before adjustments for Btu content for
gas and gravity variances for oil as well as transportation charges and
geographic location) and costs by 3.5% per year for 15 years.  This present
value was then adjusted for various individual field risks and risk adjustments
of proved non-producing reserves and proved undeveloped reserves.  The result
of this collective analysis by the Petroleum Consulting Engineers was their
estimation of the fair market values of Property Interests owned by the
Partnerships as of December 31, 1997, which estimates are set out for each
Partnership in its specific Partnership Supplement.

         CIBC Oppenheimer's evaluation of the Partnerships' Property Interests
began with the PV-10 Value of each property group, as calculated by Swift and
audited by H.J. Gruy, which Gruy reserve report is attached to each Partnership
Supplement as Attachment D.  CIBC Oppenheimer then divided the property groups
("Property") into two categories.  Those property groups with reserves
consisting primarily of proved





                                       59
<PAGE>   76
developed producing reserves were placed in the "Conventional Case" category.
Those property groups with significant proved developed non-producing or
undeveloped reserves were placed in the "Non-Conventional Case" category.  CIBC
Oppenheimer then valued each property group by applying the multiples discussed
under "Valuation Multiples" above in this section to each property group's
PV-10 Value, proved reserves on a BOE basis, and projected 1998 EBITDA.  A
separate set of multiples was used for property groups in the Conventional Case
category and the Non-Conventional Case category, respectively.  This provided
CIBC Oppenheimer with three estimated values for each property group.  The
average of these three values yielded CIBC Oppenheimer's estimation of the fair
market value of each property group.  CIBC Oppenheimer then allocated the
appropriate portion of the each property group's estimated fair market value to
the Partnership based upon the Partnership's Property Interest in each property
group.  The result of this analysis by CIBC Oppenheimer was an estimation that
the fair market value of the Partnership's Property Interests which are set out
for each Partnership in its specific Supplement.

         The Special Transactions Committee has determined that, in keeping
with the definition of Fair Market Value, the higher of these two estimations
of fair market value, represents the Fair Market Value of the Partnerships'
Property Interests, which are set out for each Partnership in its specific
Supplement.  Accordingly, the fair market value estimation of the Petroleum
Consulting Engineers and the fair market value determined by CIBC Oppenheimer
were compared to each other and the higher of the two for each Partnership was
chosen as the Fair Market Value of the Property Interests owned by that
Partnership.  The variations between the fair market value estimates prepared
by the Petroleum Consulting Engineers and CIBC Oppenheimer had a weighted
average deviation which ranged from 0.025% to 16%, with an average of 1%.

DETERMINATION OF PREMIUM OVER FAIR MARKET VALUE BY THE COMPANY

         Choice of Higher of Two Appraisals

         The Special Transactions Committee presented their recommendation to
the Board of Directors of the Company as to the Fair Market Value of the
Property Interests of the Partnerships.  The proposed sale of the Partnerships'
Property Interests to the Managing General Partner and the procedures
established for the appraisal of fair market value for such interests was
approved by vote of all of the members of the Board of Directors (other than
one absent director) of the Company based upon the recommendation of the
Special Transactions Committee.  The Board of Directors also determined to
consider whether it was appropriate to pay a premium over the Fair Market Value
in purchasing the Property Interests from each of the Partnerships.

         Decision to Add 7.5% Premium

         The Company determined that paying a 7.5% premium over the appraised
fair market value of the Partnerships' Property Interests was appropriate and
fair based upon the factors and for the reasons discussed below.  The amount of
the premium principally was based upon management's experience in purchasing
properties which contain both producing reserves and drilling potential.
Because the Managing General Partner has served in that capacity on behalf of
all of the Partnerships for a number of years, it is intimately familiar with
the Property Interests owned by each of the Partnerships.  The Managing General
Partner believes that if the Property Interests were to be sold to a third
party purchaser who was not equally familiar with those interests, it is likely
that the purchaser would discount the purchase price to account for that lack
of familiarity and perceived potential risks.  If these interests are purchased
by the Company, then the additional cost and personnel often inherent in making
a property acquisition are not required, because the files and deed records
already exist in the Company's lease and computer systems, and conveyance and
title issues do not exist.





                                       60
<PAGE>   77
Since 1979, the Company, on behalf of itself and others, has gained a wide
range of experience with the valuation of oil and gas properties and the prices
for their purchase and sale, having purchased $478 million of such properties
in 129 separate transactions.

         In the judgment of the Company, the purchase of any Partnership's
Property Interests, together with interests in many of the same properties
owned by other Partnerships at approximately the same time, will result in
efficiencies to the Company in aggregating such interests.  Swift's long-term
knowledge of the risks involved in these properties means that it is in a
better position to evaluate these risks than third parties.

         Based upon the Company's experience in purchasing properties, the lack
of additional costs often incurred in purchasing oil and gas properties in
which the purchaser has owned no interest, and the Company's intimate
familiarity with these Property Interests and consequent ability to evaluate
acquisition risks, it was deemed appropriate to pay a premium representing the
benefit to the Company arising from these factors.

         The amount of the premium principally was based upon management's
experience in purchasing properties which contain both producing reserves and
drilling potential.  No attempt was made to distinguish between the Property
Interests owned by any particular Partnership, nor was any statistical or
analytical study prepared by the Company on a separate basis in the course of
determining the amount of this premium.

         Other purchasers might have determined it inappropriate to pay  a
premium, or if so, to pay a premium based upon other factors or in a different
amount.  Because there has been no independent determination to pay this
premium or of its amount, and no fairness opinion has been requested regarding
this premium, conflicts of interest exist in its determination, although the
Managing General Partner believes, based upon its knowledge of the oil and gas
industry, its knowledge of the properties involved, its experience in
purchasing and selling oil and gas properties, and the benefits from purchasing
the Property Interests which are particular to the Company, that the amount
being offered to the Partnerships to purchase their Property Interests is fair.

         Amounts to be Paid to Investors Upon Liquidation of their
Partnerships.

         The evaluation of the fair market values of the Property Interests of
the Partnerships were based upon values as of December 31, 1997, including the
fair market value estimates by the Petroleum Engineering Consultants (using
pricing assumptions and reserve quantities at that time) which were in turn
based upon the audit of each of the Partnerships' total proved reserves at that
date by H.J. Gruy.  As is the case with all oil and gas purchases, the purchase
is proposed to be made as of the date which the properties were evaluated (in
this case December 31, 1997).  Obviously, the quantities of reserves being
purchased are reduced by production which takes place after the evaluation date
(net of the lease operating cost incurred to produce such reserves) but before
the purchase takes place.

         Therefore, the actual purchase price to be paid to each Partnership
for its oil and gas assets is the purchase price set out in the table contained
in the Summary and the individual Partnership Supplement for each Partnership,
reduced by the net revenues that have been received by that Partnership for
production during 1998.  Money received by each Partnership from the sale of
such production during 1998 has been paid to such Partnership.  The
Partnerships have continued to make quarterly cash distributions during 1998.
A portion of 1998 revenues, therefore, have already been distributed to their
partners during 1998 and the remainder of revenues from 1998 production will be
distributed as part of that Partnership's liquidating distribution.





                                       61
<PAGE>   78
         Portion of Purchase Price Payable to the Managing General Partner

         The total purchase price for the oil and gas assets of all 63
Partnerships is approximately $81 million.  Of this amount, approximately $14
million represents the portion of the purchase price which is payable to the
Managing General Partner by virtue of the Managing General Partner's interest
in the Partnerships.  Approximately $11 million of this is attributable to its
interests as a general partner and $3 million attributable to the units which
it has purchased under the right of presentment set out in the various
Partnership Agreements.  Therefore, the amount payable to purchase all of the
oil and gas assets of all 63 Partnerships net of the amount distributable to
the Managing General Partner itself upon liquidation of the Partnerships is
approximately $67 million as of December 31, 1997 before any reduction for 1998
production.

FAIRNESS OF PROPOSED SALE

   
         The Managing General Partner believes that the entire transaction
related to the Proposals involving the proposed method of sales of the
Partnerships' Property Interests is fair to Investors for the following
reasons, without giving any particular weight to any reason:
    

         1.      The Managing General Partner believes that the most important
                 element of the Proposals is the determination of the Fair
                 Market Values of the Partnerships' Property Interests.  The
                 prices to be paid by the Company to purchase the Partnerships'
                 Property Interests was determined in the Managing General
                 Partners' sole judgment by adding a 7.5% premium to the higher
                 of the Appraisers' two estimates of the fair market value on a
                 Partnership-by-Partnership basis of the Partnerships' Property
                 Interests.  Two of the three Appraisers are qualified
                 independent petroleum engineering firms and the other is an
                 investment banking firm.  The factors and methods used by the
                 Appraisers in determining Fair Market Value are discussed in
                 detail under "Independent Appraisal of the Fair Market Value
                 of Partnerships' Property Interests."

         2.      No transaction will take place in a particular Partnership
                 unless the Proposal is approved by Investors holding at least
                 a majority of the interests in such Partnership (without any
                 vote by the Managing General Partner) and a similar Proposal
                 is approved by such Partnership's companion Partnership.

         3.      The Special Transactions Committee made the determination as
                 to the retention of the Appraisers and approved the fair
                 market value estimates provided by the Appraisers and
                 recommended the reports of the Appraisers to the Board of
                 Directors of the Company.  The Special Transactions Committee
                 is comprised solely of independent directors of the Company.

         4.      If any of the Proposals are approved by Investors, it is
                 likely that the Managing General Partner will expend the
                 capital necessary to develop various non-producing reserves on
                 the Property Interests purchased by the Managing General
                 Partner.   If all of the Property Interests which are
                 the subject of the Proposals are acquired by the Company, such
                 Property Interests in the aggregate will constitute less than
                 20% of the Company's total assets.  Because the Managing
                 General Partner would be the beneficiary of any such increase
                 in value, the Managing General Partner is hereby offering to
                 Eligible Purchasers the opportunity to purchase up to
                 2,500,000 shares of Common Stock of the Company.  There is no
                 requirement that any purchase of Swift's Common Stock be made.
                 See "Offer to Eligible Purchasers" below.





                                       62
<PAGE>   79
         5.      In structuring the Proposals and related transactions, the
                 Managing General Partner considered that any sale of
                 Partnership Property Interests, whether to the Managing
                 General Partner or to a third party, would be a taxable
                 transaction.  Thus, if an Investor subject to federal income
                 tax chooses to use the proceeds received on liquidation of
                 that Investor's Partnership to purchase Swift Common Stock,
                 tax will still have to be paid on the amount of any taxable
                 income resulting from the liquidation of that Investor's
                 Partnership, whether or not the Investor has available cash
                 proceeds remaining from his liquidating distribution after
                 some or all of such proceeds are used to purchase Common
                 Stock.

         The individual Partnership Supplements contain an estimate of the
liquidating net cash distributions payable to Investors if their Partnership's
Proposal is approved, along with an estimate of the net cash distributions to
Investors from their Partnership continuing to operate for the remaining life
of that Partnership's reserves.  In all but three Partnerships the estimated
amount receivable from continuing operations is higher than the amount which
Investors will receive if the Proposals are approved.  Despite this difference,
which ranges from 3% to 48%, depending upon the particular Partnership, the
Managing General Partner believes that the Proposals are fair.  The estimates
of distributions from continuing operations are based upon continuation of
current oil and gas prices over a 17 to 20 year period.  Continued volatility
in the markets for oil and gas therefore make this estimation subject to
significant variance based upon pricing changes.  In addition, there are
significant operational risks over such a long period of time to which each of
the Partnerships would be subject.   Current cash distributions paid in one
lump sum currently are not subject to these risks.

         The fairness of the Proposals for the 18 Partnerships formed in the
fourth quarter of 1986, the first three quarters of 1987, and between the
fourth quarter of 1992 and the second quarter of 1994, the majority of whose
proved reserves are non-producing, should be assessed in light of the benefit
to the Managing General Partner of being able to use its capital resources to
drill wells to develop undeveloped reserves, in addition to the possible
benefit of holding such interests for a period of time sufficient to allow
completion of wells in different zones in order to produce behind-pipe
reserves.

         Notwithstanding the above, determinations made by the Special
Transactions Committee, the independent Appraisers' determination of the fair
market value of the properties, and the payment of a 7.5% premium does not
necessarily remove the substantial conflicts of interest which exist due to the
Managing General Partner acting on behalf of the Partnerships and also acting
as the purchaser of the Property Interests from the Partnerships.  No fairness
opinion was requested or received regarding the ultimate purchase price to be
paid by the Managing General Partner to purchase the Partnerships' oil and gas
or assets.  Rather than setting the purchase price for Partnership Property
Interests itself, the Managing General Partner determined it would be
preferable to request three different independent Appraisers, using two
different appraisal methods to determine fair market values at which such
Property Interests should be purchased.  The Managing General Partner then
chose the higher of the two values for each Partnership.  The Managing General
Partner believes that adding a 7.5% premium to the highest of the fair market
value determinations made by the three Appraisers only increases the amount to
be paid to Investors upon liquidation of their Partnerships and does not
require a separate fairness opinion.  The Managing General Partner believes
that when the Appraisers rendered their opinion as to the "fair market value"
of each Partnership's Property Interests, inherent within that appraisal was
the appraiser's determination that these "fair market values" were "fair," or
such determination would not have been made.  Consequently, no independent
fairness opinion upon the premium was requested.  The determination of a
different third party purchaser as to the purchase price to be paid might be
more or less than that being proposed to be paid by the Managing General
Partner.

         The determination to submit proposals to Investors in which the
Managing General Partner would purchase the Property Interests of the
Partnerships was deemed by the Managing General Partner to be the most
preferable means of addressing the appropriate time for liquidation of the
Partnerships and the method of doing so.  This decision was made after full
consideration by the Managing General Partner of its fiduciary obligations to
Investors.  Furthermore, the decision to use three Appraisers, rather than one,
and to have the Appraisers actually set the fair market value for purchase of
the properties, rather than the Managing General Partner setting that value and
requesting a fairness opinion and the decision to add the 7.5% premium, was
based upon the Managing General Partner's consideration of the substantial
conflicts of interest which exist in the transactions covered hereby, which are
detailed herein.

   
          FEDERAL INCOME TAX CONSEQUENCES OF ADOPTION OF THE PROPOSALS

GENERAL

         In the opinion of Hoops & Levy, L.L.P., Special Tax Counsel,  the
following summarizes material federal income tax consequences to the Investors
arising from the Partnerships' proposed sale of their oil and gas operating and
non- operating properties and liquidation pursuant to the Proposals.  This
Section of the Registration Statement is subject to and conditioned upon all
matters set forth in the written opinion of Special Tax Counsel dated ________,
and included as an exhibit to the Registration Statement.  As set forth herein,
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 reported judicial decisions and published positions of the
Internal Revenue Service (the "Service"), and upon further assumptions that the
Partnerships constitute partnerships for federal tax purposes and that the
Partnerships will be liquidated as described herein.  Statements of legal
conclusions regarding tax consequences also are based upon private letter
rulings dated October 5, 1987 and August 22, 1991, with respect to Swift Energy
Managed Pension Assets Partnerships and February 6, 1991, with respect to Swift
Energy Pension Partnerships.  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 Investors.
Although the Special Tax Counsel understands that Investors will rely to a
degree on its opinion,  Investors should recognize that an opinion of Special
Tax Counsel represents merely such counsel's best legal judgment and has no
binding effect on any federal or state governmental entity or courts or
official status of any kind.  For a discussion of the tax consequences that may
result from an Investor's election to receive common stock in lieu of cash upon
a partnership's liquidation reference should be made to "Material Federal
Income Tax Consequences of Electing to Receive Common stock in Lieu of Cash
upon Partnership Liquidation."

         Under written request of an Investor or his or her representative, the
Company will promptly transmit a copy of the tax opinion, without charge to the
Investor.  Requests should be directed to Mr. Steven Yakle, Assistant
Controller, Swift Energy Company, 16825 Northchase Drive, Suite 400, Houston,
Texas  77060.

         This summary does not describe all the tax aspects which may affect
Investors because the tax consequences may vary depending upon the individual
circumstances of an Investor.  It is generally directed to Investors that are
individuals, qualified plans and trusts under Code Section 401(a) or 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 Partnerships as "capital assets" (generally, property held for investment).
Each Investor is strongly encouraged to consult its own tax advisor as to the
rules which are specifically applicable to such Investor.  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

         This section applies to Tax Exempt Plans that are Investors in either
of the two series of partnerships which invested in only non-operating
interests, the 13 Swift Energy Managed Pension Assets Partnerships ("SEMPAP")
partnerships formed between 1988 and 1990, or the 13 Swift Energy Pension
Partners ("SEPP") partnerships formed between 1991 and 1994.

         Sale of Property Interests and Liquidation of Partnerships

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

         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 Service has previously ruled that the Partnerships' Property
Interests, as structured under the net profits agreements, are royalties, as
are any overriding royalties the Partnerships may own.  To the extent that the
Property Interests are not debt-financed property, neither the sale of the
Property Interests by the Partnerships nor the liquidation of the Partnerships
are expected to cause Investors that are Tax Exempt Plans to recognize taxable
gain or loss for federal income tax purposes, even though there may be gain or
loss upon the sale of the Property Interests for federal income tax purposes.
The foregoing assumes Investors have not borrowed funds to acquire their
partnership interests.

         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.
    





                                       65
<PAGE>   82
   
         If an Investor 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 Interests may be UBTI, see "Tax Treatment of Investors Subject to
Federal Income Tax" below.  The Managing General Partner has represented that
(i) the Partnerships did not borrow money to acquire their Property Interests,
and (ii) that the Property Interests of the Partnerships are not subject to any
debt, mortgages or similar liens that will cause the Partnerships' Property
Interests 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 Interests
are not expected to be considered debt-financed property.

TAX TREATMENT OF INVESTORS SUBJECT TO FEDERAL INCOME TAX

         All references to Investors in this section refer solely to Investors
that either are not Tax Exempt Plans or are Tax Exempt Plans (a) whose
Partnership Interests are debt-financed or (b) that have invested in the Swift
Energy Income Partnerships ("SEIP") formed between 1986 and 1990, or in the
Swift Energy Operating Partnerships formed between 1991 and 1994.


         Tax Treatment of  Tax-Exempt Plans Subject to Federal Income Tax Due
to Debt-financing

         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 Interests and liquidation of the Partnerships that will be subject to
taxation as UBTI is the percentage of the Tax Exempt Plan's share of
Partnership income, gain, loss and deduction adjusted by the following
calculation.  Section 514(a)(1) includes, with respect to each debt-financed
property, as gross income from an unrelated trade or business an amount which
is the same percentage of the total gross income derived during the taxable
year from or on account of the property as (i) the average acquisition
indebtedness for the taxable year with respect to the property is of (ii) the
average amount of the adjusted basis of the property during the period it is
held by the organization during the taxable year (the "debt/basis percentage").

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

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





                                       66
<PAGE>   83
   
         Taxable Gain or Loss Upon Sale of Properties

         An Investor will realize and recognize gain or loss, or a combination
of both, upon his 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 such
Partnership and allocated to such Investor (i.e., cash or consideration
received) over the Investor'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 Investor's tax basis
over the amount realized by such Partnership for such property and allocated to
such Investor.  Investors in Swift Energy Income Partnerships ("SEIP") or Swift
Energy Operating Partnerships ("SEOP") are not expected to realize any gain or
loss on property acquired from a SEMPAP or SEPP partnership and immediately
sold by the acquiring Partnership to the Managing General Partner.  It is
projected that SEIP and SEOP Partnerships will realize taxable gain upon the
sale of the Partnership properties (other than those acquired from SEMPAP or
SEPP partnerships) and that SEMPAP and SEPP Partnerships will realize taxable
loss upon the sale of Partnerships properties.  Such gain or loss will be
allocated among the Investors in accordance with the Partnership Agreements.
The Partnership Agreements include allocation provisions that require
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 Investor will realize and
recognize his allocable share of gains and losses in his tax year within which
the Partnership properties are sold.

         Factors Solely Applicable to All Investors in SEIP and SEOP
Partnerships (Partnerships holding working interests)

         Because the oil and gas properties, and related assets owned by the
SEIP and SEOP Partnerships are  properties used in a trade or business, the
character of gains and losses realized by the Partners generally will be
governed by Section 1231 of the Code.  Deductions for intangible drilling and
development costs, depletion and depreciation expenses with respect to these
properties, however, may be subject to recapture as ordinary income, in an
amount which does not exceed gain recognized.  With respect to properties
placed in service after 1986, Code Section 1254 recaptures all intangible
drilling and development costs and depletion (to the extent of basis) as
ordinary income.  The SEIP and SEOP Partnerships did not incur material amounts
of intangible drilling and development costs, and accordingly the recapture of
same is not expected to be material.

         Each Investor's recognized allocable share of the net Partnership 1231
gains or losses must be netted with that Investor's individual section 1231
gains and losses recognized during the year in order to determine the character
of such net gains or net losses under section 1231.  Net gains will be treated
as capital gains except to the extent recharacterized as ordinary income due to
recapture and net losses will be treated as ordinary losses.

         Liquidation of the Partnerships

         After sale of their properties, the Partnerships' assets will consist
solely of cash which they will distribute to their partners in complete
liquidation.  The Partnerships will not realize gain or loss upon such
distribution of cash to their partners in liquidation.  If the amount of cash
distributed to an Investor in liquidation is less than such Investor's adjusted
tax basis in his Partnership interest, the Investor will realize
    





                                       67
<PAGE>   84
   
and recognize a capital loss to the extent of the excess.  If the amount of
cash distributed is greater than such Investor's adjusted tax basis in his
Partnership interest, the Investor will recognize a capital gain to the extent
of the excess.  Investors in SEIP and SEMPAP Partnerships paid a portion of
syndication and formation costs upon entering his or its Partnership, neither
of which costs were deductible expenses, therefore it is anticipated that
liquidating distributions to Investors in SEIP and SEMPAP Partnerships will be
less than such Investors' bases in their Partnership interests and thus will
generate capital losses.

         Capital Gains Tax

         Net long-term capital gains of individuals, trusts and estates
generally will be taxed at a maximum rate of 20%, while ordinary income,
including income from the recapture of depletion, will be taxed at a maximum
rate depending on that Investor'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
Investor during the tax year, plus $3,000 ($1,500, in the case of a married
individual filing a separate return).  The excess amount of such net long-term
capital loss may be carried forward and utilized in subsequent years subject to
the same limitations.  Corporations are taxed on net long- term capital gains
at their ordinary Section 11 rates and are allowed to carry net capital losses
back three years and forward five years.

         Passive Loss Limitations

         Investors 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.

         An Investor'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
SEMPAP or SEPP Investor's allocable share of any gain realized on sale of his
Partnership's net profits interest is expected to be characterized as portfolio
income and may not offset, or be offset by, passive activity gains or losses.

         An SEIP or SEOP Investor's allocable share of any gain realized on
sale of Partnership properties (other than gain from the sale of portfolio
investments) will be characterized as passive activity income that may be
offset by passive activity losses from other passive activity investments.
Moreover, because the sale of properties and liquidation of such Partnerships
will terminate the Investors' interest in the passive activity, an Investor's
allocable share of any loss (i) previously realized as an Investor in such
Partnership and suspended because of its passive characterization, (ii)
realized on the liquidating sale of Partnership properties, or (iii) realized
by the Investor upon liquidation of his Partnership interest, will not be
characterized as losses from a passive activity.


         THE FOREGOING DISCUSSION IS INTENDED TO BE A SUMMARY OF MATERIAL
INCOME TAX CONSIDERATIONS OF THE SALE OF PROPERTIES AND LIQUIDATION OF THE
PARTNERSHIPS.  EACH INVESTOR SHOULD CONSULT HIS, HER OR ITS OWN TAX ADVISOR
CONCERNING SUCH INVESTOR'S PARTICULAR TAX CIRCUMSTANCES AND THE FEDERAL, STATE,
LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES TO HIM OR IT OF THE SALE OF
PROPERTIES AND THE LIQUIDATION OF HIS OR ITS PARTNERSHIP.
    





                                       68
<PAGE>   85
CONSIDERATION OF ALTERNATIVE TRANSACTIONS

         The Managing General Partner has given consideration to a number of
different alternatives prior to submitting the Proposals to Investors for their
approval.  These alternatives included continued operation of the properties
for a longer period, offering the Partnerships' remaining property interests at
auction or selling them in negotiated transactions.  For the reasons discussed
at greater length under "The Proposal--Reasons for the Proposal" below, the
Managing General Partner believes that a sale at this time is preferable to
continued operations of the Partnerships.  Although in the past certain
marginal Property Interests have been sold in negotiated transactions or at
auction, the Managing General Partner does not believe that such methods of
sale are likely to maximize the value of the Partnerships' Property Interests,
as discussed below.

         Continuing Operations

                 As discussed above under "Fairness of Proposed Sale," the
         estimates of the liquidating net cash distributions payable to
         Investors if the Partnerships' Proposals are approved is less than the
         estimate of net cash distributions to Investors if their Partnerships
         continue to operate for the remaining lives of their reserves.  For
         reasons discussed at greater length under "Special Factors--Reasons
         for the Proposal" above, the Managing General Partner believes that a
         sale at this time is preferable to continuing operations of the
         Partnerships.  There are a number of assumptions contained in the
         estimates of distributions from continued operations that may or may
         not prove to be true over the remaining life of the Partnerships'
         reserves.  Such distributions would be subject to the risks of oil and
         gas operations, in addition to the risk of continued price volatility
         for oil and gas.

         Auction

         Although offering oil and gas properties for sale at auction is often
an efficient means of selling smaller interests in properties in which the
seller is not the operator of the property, auctions are generally unsuited to
the offer and sale of substantial property interests, may exceed the normal
size of properties offered at auction, and may well be beyond the purchasing
capacity of the parties which typically are bidders at such auctions or might
lower the price or the number of interested bidders.

     o Many of the Partnerships organized by the Managing General Partner own
       significant interests in the same fields.  Consequently, if a substantial
       majority of these Partnerships approve sale of their properties, the size
       of the interests in many properties would exceed the normal size of
       properties offered at auction, and may well be beyond the purchasing
       capacity of the parties which typically are bidders at such auctions.
       Larger consolidated property interests normally bring higher prices, and
       thus there are significant reasons to sell the interests in the same
       properties owned by all of the Partnerships affiliated with the Managing
       General Partner at one time.  On the other hand, doing so at auction
       would cause such properties to dominate each auction and would likely
       lower the price or the number of interested bidders. In order to avoid
       this consequence, the interests in properties to be sold could be divided
       into smaller pieces and offered at auction on multiple occasions over
       several years, but this might be counterproductive in terms of prices
       received at auction, thus minimizing many of the benefits of taking
       properties to auction for sale.

     o A portion of the value of the properties in which the Partnerships own
       interests would remain operated by the Managing General Partner because
       it controls other interests in fields in which they are located.  This
       often negatively affects the amount a third party is willing to pay and
       the overall interest of third parties in buying such properties.  On the
       other hand, because of its control of such properties, the Managing
       General Partner is the party in the position to pay the highest price for
       such interests and the one most likely to do so.





                                       69
<PAGE>   86
     o A significant portion of the proved reserves attributed to many of the
       Partnerships' Property Interests are non-producing reserves.  Typically
       auction buyers base the prices they pay at auction upon a multiple of
       cash flow.  This methodology of auction pricing significantly discounts
       the value of non-producing reserves.

     o Because of the necessity of preparing and disseminating auction 
       information on properties to be offered and soliciting attendance by
       prospective bidders, and then screening and qualifying such purchasers,
       the transaction costs for offering properties at auction are substantial,
       and often higher than other means of sale.

Because of the various factors discussed above, the Special Transactions
Committee has determined that it would not be in the best interests of the
Partnerships to offer substantially all of their properties and assets to third
parties.

         Negotiated Sale

         Many of the same factors discussed above affect whether the
Partnerships would benefit from attempting to sell their Property Interests in
negotiated transactions, such as:

     o The fact that buyers would be purchasing many Property Interests they
       would neither control nor operate applies equally in negotiated sales,
       and might discourage interest and prices offered for such interests.

     o Likewise, the discount for non-producing reserves could exceed the
       discounts applied by the Appraisers in the case of negotiated sales of
       properties with substantial amounts of such reserves.  This factor is
       minimized to the greatest extent through the Managing General Partner's
       purchase of such Property Interests, because the Managing General Partner
       is familiar with all of these properties through its management of the
       Partnerships' interests therein over several years.

     o Lastly, sale of properties on a direct basis often involves substantial
       periods of time for due diligence, negotiation and execution of
       agreements and closings, often with different purchases for different
       properties, in addition to the necessity of taking large amounts of time
       to create and supervise data rooms or disseminate data to possible
       purchasers, plus the time needed to deal directly with multiple
       prospective purchasers. Furthermore, certain issues, such as
       environmental and title matters, may come to light in the late stages of
       a negotiated sale, which may delay or preclude the consummation of the
       sale.

         Although the Company did sell the properties of other partnerships
whose assets were liquidated between 1996 and 1998 both by means of auction and
negotiated transactions, neither form of transaction has been attempted for the
Property Interests owned by the Partnerships because of the smaller size of the
properties placed in auction in the former liquidations and the other reasons
noted above.  No offers have been received to purchase the properties owned by
the Partnerships from any third party, nor has the Managing General Partner
undertaken an effort to sell the Property Interests on behalf of any of the
Partnerships through the alternatives discussed above.

         Assessment of Investors

         The limited partnership agreements under which the Partnerships were
formed do not provide for any form of voluntary or mandatory assessment for
further capital contributions by the Investors in the Partnerships.  Given the
purpose of the Partnerships when they were formed, and the explicit Partnership





                                       70
<PAGE>   87
provisions and disclosures that no assessments would be made, the Managing
General Partner did not consider it to be appropriate to consider this  as an
alternative for funding development of non-producing reserves of the
Partnerships or otherwise invest further capital in the Partnerships'
activities.  Engaging in extensive drilling operations is contrary to the
purposes of the Partnerships and represents a higher degree of risk than
contemplated when the Partnerships were formed.  In certain Partnerships,
borrowing was forbidden or restricted by the terms of their limited partnership
agreements.  Although there was limited borrowing in the early years by certain
Partnerships, at this time lower levels of cash flow are not sufficient to
support the additional cost of borrowing and repayment.

         Third Party Tender Offer

         In June 1998, Madison Partnership Liquidity Investors 60, L.L.C. made
an offer to purchase up to 4.0% of the outstanding units of Swift Energy Income
Partners 1987-B, Ltd. from its limited partners for $5.66 per unit in cash.
[FILL IN LATER IF INFORMATION AVAILABLE:]  Upon the conclusion of the offer in
late July 1998, holders of __% of its outstanding units had tendered their
Units to Madison for purchase.  It is not known whether other tender offers
will be made to purchase Units from Investors in other Partnerships, or the
price at which such offers will be made, although based upon various securities
regulatory restrictions, it is anticipated that any such offers would cover no
more than 4.9% of outstanding Units of any one Partnership.

   
                  COMPARISON OF OWNERSHIP OF UNITS AND SHARES

         The information below highlights a number of the significant
differences between the Partnerships and the Company relating to, among other
things, form of organization, investment objectives, policies and restrictions,
asset diversification, capitalization, management structure, compensation and
fees, and investor rights, and compares certain of the respective legal rights
associated with the ownership of the Units and Shares.  These comparisons are
intended to assist Eligible Purchasers in understanding how their investments
will be changed if they elect to receive all or any portion of the distribution
they are entitled to receive in shares of Common Stock offered hereunder.  This
comparison is summary in nature and does not constitute a complete discussion
of these matters, and Eligible Purchasers should carefully review the balance
of this Joint Proxy Statement/Prospectus for additional discussions.

      Shareholders have greater control over management of the Company than the
 Investors have over the Partnerships because members of the Board of Directors
 are elected on a staggered basis annually by the Shareholders at the Company's
 annual meeting.  However, in both cases, Investors and Shareholders must rely
 upon management for the prudent administration of their investments.

         The General Partners of the Partnerships have limited liability to the
Partnerships for acts or omissions undertaken by them when performed in good
faith, in a manner reasonably believed to be within the scope of their
authority and in the best interests of the Partnerships.  The General Partners
also have, under specified circumstances, a right to be advanced expenses or
reimbursed for any loss, claim, liability, damage and expenses (including
attorneys' fees) actually and reasonably incurred by them by virtue of serving
as General Partners.  Although the standards are expressed somewhat
differently, there are similar limitations upon the liability of the directors
and officers of the Company when acting on behalf of the Company and upon the
rights of such persons to seek indemnification from the Company.

NO UNAFFILIATED REPRESENTATIVE OR FAIRNESS REPORT

         Neither the Managing General Partner nor a majority of its independent
directors retained an unaffiliated representative to act on behalf of the
Partnerships' Investors for the purposes of negotiating the terms upon which
any such sale to the Managing General Partner would be made or for the
preparation of a report concerning the fairness of such transaction.

CONSEQUENCES OF A PARTNERSHIP NOT APPROVING ITS PROPOSAL

         If the Investors in a Partnership do not approve its Proposal, such
nonparticipating Partnership will continue to operate as a separate legal
entity with its own assets and liabilities.  There will be no change in its
investment objectives, policies or restrictions, and the nonparticipating
Partnerships will continue to be operated in accordance with the terms of their
Partnership Agreement.  It is also likely that the Proposal to the companion
Partnership of any such nonparticipating Partnership will be withdrawn even if
a Proposal is approved by Investors of such companion Partnership.

PRIOR RELATIONSHIPS BETWEEN THE APPRAISERS, THE PARTNERSHIPS AND THE MANAGING
GENERAL PARTNER

         H.J. Gruy has audited the reserve evaluations for the Partnerships,
other partnerships managed by the Managing General Partner, and the Managing
General Partner itself  since their respective inceptions.  The amount paid to
H.J.  Gruy over the two most recent fiscal years by each specific Partnership
is set out in its specific Supplement.  Approximately $72,300 over the past two
years has been paid by the Managing General Partner and its affiliates to H.J.
Gruy.  In 1997, J.R. Butler provided an appraisal of the fair market value of
certain Property Interests in a particular field owned by seven limited
partnerships (not including the Partnerships) formed by the Managing General
Partner, which was the price for which those property interests were purchased
in 1998 from those seven partnerships by the Managing General Partner.  J.R.
Butler was paid approximately $38,500 over the last two years for such
appraisal services and other work performed for the Managing General Partner,
none of which was performed for any of the Partnerships.  Additionally, J.R.
Butler performed four technical studies for the Company during the period
November 1990 to October 1994.  Otherwise, there has been no preexisting
relationship between the Managing General Partner and J.R. Butler.  CIBC
Oppenheimer acted as managing underwriter of a public offering of $48.875
million of common stock for the Managing General Partner in 1995, in which the
gross underwriting discount was 5.64% and participated as an underwriter of the
Managing General Partner's 1996 public offering of $115 million of Convertible
Subordinated Notes, in which the gross underwriting discount was 3.5%.  CIBC
Oppenheimer also may be involved in future investment banking activities on
behalf of the Managing General Partner. None of the Appraisers nor any of their
personnel have any direct or indirect interest in the Managing General Partner
or the Partnerships, and the Appraisers' compensation is not contingent upon
the results of their fair market value opinions resulting from their review of
the Partnerships' properties.

         In preparing their valuation estimates, the Appraisers assumed the
accuracy and completeness of the financial and other information provided by
the Managing General Partner or which was publicly available and did not
attempt to independently verify such information.  The Appraisers  did not make
field inspections or judgments relative to environmental or other legal
liabilities.

EXPENSES

         The total expenses associated with the Proposals is estimated to be 3%
of the Fair Market Value of the Property Interests of all of the Partnerships,
or $2,250,000, comprised principally of appraisal fees of $575,000, mailing
costs of $325,000, legal and accounting fees of $750,000, printing costs of
$350,000 and other expenses (travel, telephone and other solicitation expenses,
filing fees, etc.) of $250,000.  The appraisal fees are to be paid by the
Partnerships and allocated in percentages proportionate to the Fair Market
Value of each Partnership's oil and gas assets determined by the Appraisers.
Printing, mailing and solicitation costs will be allocated among the
Partnerships according to the number of Investors in each Partnership.  The
remaining costs will be allocated according to percentages proportionate to the
Fair Market Value.  Consequently, it is estimated that the maximum amount of
these expenses allocated to any Partnership will be $127,500, and the minimum
amount will be $7,800, which generally is proportionate to the original
capitalization of each Partnership.

         The general and administrative costs of the Managing General Partner
anticipated to be incurred in connection with the Proposals and related
transactions will be covered by the normal ongoing general and administrative
cost reimbursement to it set out in each Partnership's Partnership Agreement.
The Managing General Partner has received this reimbursement on an annual basis
since inception of the Partnerships.

SOURCE OF FUNDS TO PURCHASE PARTNERSHIP PROPERTY INTERESTS

   
         The Company will use internally generated cash resources and
borrowings available under the New Credit Facility to purchase the
Partnerships' Property Interests, the net purchase price of which is expected
to be approximately $70.6 million, subject to certain reductions based on cash
flow distributions to the Partnerships prior to closing.  The principal terms
and restrictions of the New Credit Facility are described in detail in this
Joint Proxy Statement/Prospectus under "Summary--Recent Developments--New
Credit Facility."  It is anticipated that these borrowings will be repaid
through, and other capital needs will be met by, internally generated cash
flows, and other forms of debt and/or equity financing.
    

MANAGING GENERAL PARTNER BENEFITS

         The Managing General Partner will share the benefits available to
Investors through liquidating its Partnership interests (including both its
general partner's interest and any units it owns) and receiving the same value
for those interests as Investors.

         The Managing General Partner will purchase the Partnerships' Property
Interests if the Proposals are approved by the companion Partnerships.  See
"The Proposals--Estimates of Liquidating Distribution Amount."  Additionally,
by purchasing the Partnerships' Property Interests itself, the Managing General
Partner will be able to maintain its position as operator of many of the
properties in which the Partnerships own interests and for which it will
continue to receive operating fees.  The sale of any one Partnership's Property
Interests to the Managing General Partner will have no effect or an
inconsequential effect on the Managing General Partner's net book value and net
earnings.  However, the Managing General Partner is making similar Proposals to
Investors in 63 Partnerships organized for the same purposes between the years
1986 and 1994.  If the Investors in all of these Partnerships approve the
Proposals to sell all of their properties to the Managing General Partner, the
Managing General Partner anticipates, when comparing the year-end 1997 "100%
Case" reserve and balance sheet proforma information to December 31, 1997

Company historical data, that the oil and gas interests acquired would increase
the Company's total proved reserves on a gas equivalent basis by approximately
26%, and would increase the Company's cash flow and total assets by
approximately 25% and 19%, respectively.  Furthermore, the Company intends to
invest capital in developing certain of the properties' non-producing reserves
acquired from the Partnerships which approve the sale of their Property
Interests to the Company, depending upon the Company's assessment of each
property, characteristics and changes from time to time in the price of oil and
gas.  The Company intends to profit from this activity through a return on the
capital used and purchase such assets and invest in their development.  The
Managing General Partner is making its recommendations as set forth below, on
the basis of its fiduciary duty to the Investors, rather than on the basis of
the direct economic impact on it in its corporate capacity.

         If individual Investors in Partnerships which approve the Proposals to
sell their oil and gas assets elect to purchase Company Common Stock, rather
than receiving cash upon liquidation of their Partnership, the Company will
benefit through not having to use its available cash resources or borrowing
facilities to pay for the purchase of Partnership Property Interests, through
instead being able to issue stock to pay for a proportion of the Property
Interests purchased.

         No sale of a Partnership's Property Interests can take place without
approval by that Partnership's Investors, including any future sale to the
Managing General Partner if the Partnership does not approve its Proposal.  If
a Partnership rejects its Proposal, the Managing General Partner does not
contemplate presenting a similar proposal to that Partnership in the near
future, nor is there any assurance that any other proposal for liquidation of
that Partnership would be presented, or if so whether it would be similar to
the Proposals.

         The advantages to the Company from acquiring the Partnerships'
Property Interests at this time, as opposed to a future date, are: (1) the
Company currently has access to capital resources which could be used to
further develop the Property Interests being acquired; (2) the price of oil and
gas could increase subsequent to the date of acquisition; (3) the Company is in
the business of purchasing oil and gas properties and increasing its reserves,
and the acquisition of the Property Interests at this time allows it to do so
currently; (4) and the drilling costs could increase at a future date.

    INVESTORS ARE URGED TO COMPLETE, SIGN AND DATE THE ENCLOSED PROXY AND
            TO RETURN IT TO THE MANAGING GENERAL PARTNER NO LATER
                       THAN ___________________, 1998.

                                 THE PROPOSALS

GENERAL

         The Managing General Partner has proposed that the Partnerships'
Property Interests be sold, the Partnerships be dissolved and that the Managing
General Partner, acting as liquidator, wind up the Partnerships' affairs and
make final distributions to Investors.

         Pursuant to the terms of the Partnership Agreements, the
Partnerships, if not terminated earlier, will continue in being for a finite
period specified in their Partnership Agreements (usually 25 years), at which
point they will terminate automatically.

         This Joint Proxy Statement/Prospectus is being provided by the Company
in its capacity as the Managing General Partner of the particular Partnership
designated on the Notice of Special Meeting contained in the package with this
Joint Proxy Statement/Prospectus.  It is being provided to holders of either
the units of limited partnership interests representing an initial investment
of $100 or $1,000, depending on the particular Partnership, per unit in those
Partnerships formed prior to April 1, 1991 and to holders of depositary
interests (singly, the "SDIs," and collectively with the units, the "Units"
unless the context requires otherwise) representing an initial investment of
$1.00 per SDI in those Partnerships formed after April 1, 1991.  This Joint
Proxy Statement/Prospectus and the enclosed Form of Proxy are being provided
for use at the Special Meetings of Investors of each of the Partnerships and at
any adjournment of any of such meetings (the "Meeting") to be held at 16825
Northchase Drive, Houston, Texas at 4:00 p.m. Central Time on ______, 1998.
The Meetings are being called for the purpose of considering and voting upon
the proposal to sell all of the oil and gas assets of the Partnerships to Swift
Energy Company, and to dissolve, wind up and terminate the Partnerships (the
"Proposals"), and to transact such other business as may be properly presented
at the Special Meeting or any adjournments or postponements thereof, all in
accordance with the terms and provisions of each Partnership's Limited
Partnership Agreement (the "Partnership Agreement"), and the Texas Revised
Limited Partnership Act (the "Texas Act").  This Joint Proxy
Statement/Prospectus and enclosed Form of Proxy are first being mailed to
Investors on or about August ___, 1998.

VOTE REQUIRED

         Under the Partnership Agreements, the Proposals must be approved by
the affirmative vote of Investors holding either (1) a majority or (2) at least
51% of the Units or SDIs, respectively, then held by Investors in each
particular Partnership as of the Record Date (as defined).  Therefore, an
abstention by an Investor will have the same effect as a vote against the
Proposal.  The solicitations are being made for votes in favor of the Proposals
(which will result in liquidation and dissolution of the Partnerships).  The
number of Units outstanding (excluding the Managing General Partner's Units)
and the number of record holders are set out in each Partnership's specific
Supplement.  Each Investor appearing on the records of the Partnership as of
______, 1998 (the "Record Date") is entitled to notice of their respective
Meeting and is entitled to one vote for each  Unit or SDI held by such
Investor, as the case may be.  VJM Corporation, a California corporation, is
the Special General Partner of the Partnerships, and owns between a 0.5% and
1.5% interest in each of the Partnerships as a General Partner, but owns no
Units or SDIs.  The Managing General Partner owns a general partner's interest
in each of the Partnerships, which varies between 9.0% and 14.25%, depending
upon the particular Partnership and whether it has reached payout.
Additionally, the Managing General Partner owns a certain percentage of the
outstanding Units




                                      85
<PAGE>   102
or SDIs in many Partnerships, which ownership results from the Managing General
Partner's purchase over the life of the Partnerships of Units or SDIs from
Investors under the Right of Presentment, which is contained in each of the
Partnership Agreements.  Under the Partnership Agreement of each of the
Partnerships, the Managing General Partner may not vote any Units or SDIs owned
by it for matters such as the Proposals.  The Managing General Partner's
non-vote, in contrast to abstention by Investors, will not affect the outcome,
because for purposes of adopting the Proposals its Units are excluded from the
total number of voting Units.

         See "The Proposal--General" herein.  See "The Proposal--Reasons for
the Proposal" and "Business of The Partnership--Transactions Between the
Managing General Partner and the Partnership."

PROXIES; REVOCATION

   
         A sample of the form of proxy is attached to this Joint Proxy
Statement/Prospectus.  The actual proxy to be used to register your vote on
your Proposal before you is the separate green sheet of paper included with
this Joint Proxy Statement/Prospectus.  PLEASE USE THE GREEN PROXY TO CAST YOUR
VOTE ON THE PROPOSAL.
    

         If a proxy is properly signed and is not revoked by an Investor, the
Units it represents will be voted in accordance with the instructions of the
Investor.  If no specific instructions are given, the Units will be voted FOR
the Proposal.  An Investor may revoke his proxy at any time before it is voted
at the Meeting.  Any Investor who attends the Meeting and wishes to vote in
person may revoke his proxy at that time.  Otherwise, an Investor 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.

SOLICITATION

         The solicitations are being made by the Partnerships.  The
Partnerships will bear the costs of the preparation of this Joint Proxy
Statement/Prospectus and of the solicitation of proxies and such costs for each
Partnership will be allocated to the Investors and to the General Partners
according to their respective percentage interests set out, usually either 90%
and 10% respectively, or 85% and 15%, respectively, pursuant to the Partnership
Agreement.  If, for example, the Managing General Partner holds approximately
5% of the Units held by all Investors, 5% of the costs borne by the Investors
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 or temporary employees
of the Managing General Partner may, 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 Investors to
encourage the return of proxies, although it does not anticipate doing so.

SIMULTANEOUS PROPOSALS TO COMPANION PARTNERSHIPS

         Simultaneous Proposals are being made to Investors of so-called
companion Partnerships.  For example, simultaneously with the Proposal to
Investors to ultimately sell all of a specific Partnership's Property
Interests, a similar Proposal is being made to the Investors of the companion
Partnership which




                                      86
<PAGE>   103
owns either the working interest or the non-operating interest in the same
properties.  If both Partnerships do not approve the Proposal, it is likely to
affect the ability of both Partnerships to consummate the sale of their
Property Interests.  Although the Investors in one Partnership may desire to
sell their Property Interests, the separation of the working interest and the
non-operating interests in the same properties may affect the salability of
those interests on a permanent basis.  The value of a working interest burdened
by a large non-operating interest is likely to be lowered significantly.
Conversely, the value of a non-operating interest is likely to be negatively
affected by the lack of control over operations.  If the two Partnerships
owning the operating and non-operating interests in the same properties do not
both approve the Proposals to sell their Property Interests and liquidate the
Partnerships, it is likely that the Proposals to both Partnerships will be
withdrawn and the value of both Partnerships' Property Interests will be
reassessed.  If a Pension Partnership's companion Operating Partnership does
not approve its Proposal to liquidate and sell its Property Interests, and the
Managing General Partner is the operator of that Partnership's properties, then
it is possible but not certain that the Pension Partnership's Property Interest
might be sold under the terms set out in the Proposal.  If one of the two
companion Partnerships does not approve its Proposal, then the Managing General
Partner will advise the Investors of such Partnerships accordingly.

         If the Investors of companion Partnerships do not vote in favor of the
Proposals, then it is likely that the Partnerships will continue operations and
will produce their reserves until depletion with steadily decreasing rates of
cash flow and consequently steadily decreasing amounts of cash distributions to
the Investors.

         The following ten Partnerships, all formed as Swift Energy Income
Partners Partnerships, do not have Companion Partnerships: 1986-D, Ltd.;
1987-A, Ltd.; 1987-B, Ltd.; 1987-C, Ltd.; 1987-D, Ltd.; 1988-A, Ltd.; 1989-3,
Ltd.; 1989-4, Ltd.; 1990-1, Ltd.; and 1990-2, Ltd.

STEPS TO IMPLEMENT THE PROPOSALS

         Following the approval of the Proposals by companion Partnerships, the
Managing General Partner intends to take the following steps to implement the
proposals:

         i.      Pay the purchase prices of the Property Interests, transfer
                 the Pension Partnerships' Property Interests to their
                 companion Operating Partnerships, and execute assignments and
                 other instruments to accomplish such sale (including documents
                 to be executed together by the companion Partnerships);

         ii.     Pay or provide for payment of the Partnerships' liabilities
                 and obligations to creditors, if any, using the Partnerships'
                 cash on hand and sales proceeds;

         iii.    Conduct final accountings in accordance with the Partnership
                 Agreements and make final liquidating distributions;

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

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




                                      87
<PAGE>   104
         vi.     File Certificates of Cancellation on behalf of the
                 Partnerships with the Secretary of State of the State of
                 Texas.

ESTIMATED SELLING COSTS

         The expenses associated with the sale of the Partnerships' Property
Interests are expected to be approximately 3% of the Fair Market Value of the
Partnerships' Property Interests, primarily comprised of third party costs
incurred, including the costs of the Appraisers, legal counsel and auditors,
printing and mailing costs and related out-of-pocket expenses. The general and
administrative costs of the Managing General Partner anticipated to be incurred
in connection with the Proposals and related transactions will be met through
the normal ongoing fee set out in the Partnerships' Limited Partnership
Agreements.  See "Voting on the Proposals--Solicitation."

RECOMMENDATION OF THE MANAGING GENERAL PARTNER

   
         The Managing General Partner believes that it is in the best interests
of the Investors to liquidate and dissolve the Partnerships.  Liquidation will
allow the Investors to receive the remaining value of Partnerships' reserves
currently, rather than receiving distributions over the remaining life of the
Partnerships, and to redeploy such assets.  This removes the risk of future
decreases and continued volatility in oil and gas prices during the lengthy
period necessary to produce the Partnerships' interests in remaining reserves.
The Managing General Partner believes that general improvements over the last
several years in the level of natural gas prices relative to prices in the
mid-1990's make this an appropriate time to consider the sale of the
Partnerships' Property Interests.  If operations continue over many years,
revenues will continue to decline while direct, operating, general and
administrative expenses continue, reducing cash distributions.  Continued
operations also mean continuation of the additional costs incurred by the
Investors, including the costs associated with inclusion of information from
the Schedule K-1 relating to the Partnerships in their personal income tax
returns, while reserves continue to decline.  Termination of the Partnerships
will allow preparation of final tax returns and certain additional deductions
may be generated in connection with these terminations.
    

                THE MANAGING GENERAL PARTNER RECOMMENDS THAT THE
                       INVESTORS VOTE FOR THE PROPOSALS.

                             CONFLICTS OF INTEREST

         There are substantial conflicts of interest which exist by virtue of
the Managing General Partner acting in that capacity on behalf of all 63
Partnerships while at the same time acting as the proposed purchaser of all of
the oil and gas assets of the Partnerships.  Furthermore, the Company proposes
to offer shares of its Common Stock to those Investors which own interests in
Partnerships that sell their oil and gas properties to the Company and
liquidate.  These conflicts of interest are discussed below.  See also "Special
Factors--Managing General Partner Benefits."

FIDUCIARY DUTIES OF MANAGING GENERAL PARTNER

         The Managing General Partner has fiduciary duties to each of the
Partnerships that go beyond the specific duties and obligations imposed upon
them under the partnership agreements.  The Managing General Partner in
handling the affairs of the Partnerships is expected to exercise good faith, to
use care and prudence and to act with an undivided duty of loyalty to the
Investor.  Under these fiduciary duties, the Managing General Partner is
obligated to ensure that each Partnership is treated fairly and equitably in
transactions with third parties, especially where consummation of such
transactions may result in the interests of the Managing General Partner, being
opposed to, or not totally consistent with, the interests of the Investors.
Accordingly,  the Managing General Partner is required to assess whether the
Company's offer to each Partnership is fair and equitable, taking into account
the unique characteristics of each Partnership which affect the value of such
Partnership's assets, and comparing these factors against similar factors
affecting the value of the oil and gas assets held by the other Partnerships.
As discussed in "The Proposals--Reasons for the Proposals" in detail, after
consideration of the terms and conditions of the Proposals, the Managing
General Partner is recommending that Investors vote for the Proposals.

LACK OF INDEPENDENT REPRESENTATION

         The Managing General Partner has not retained an independent
representative or representatives to act on behalf of the Investors of each of
the Partnerships in structuring and negotiating the terms and conditions
(including the consideration to be received) upon implementation of the
Proposals.  No group of Investors was empowered to negotiate the terms and
conditions of the Proposals or to determine what procedures should be in place
to safeguard the rights and interests of the Investors.  In addition, no
investment banker, attorney, financial consultant or expert was engaged to
represent the interests of the Investors.  On the contrary, the Managing
General Partner and the executive management of the Company have been the
parties responsible for structuring all the terms and conditions of the
Proposals.  Legal counsel engaged to assist with the preparation of the
documentation for the Proposals, including the Joint Proxy
Statement/Prospectus, was engaged by the Company and did not serve, or purport
to serve, as legal counsel for the Investors.  If an independent representative
or representatives had been retained for the Partnerships, the terms of the
Proposals might have been different and possibly more favorable to the
Investors.

         The Managing General Partner does not believe it was necessary to
engage as independent representative to represent the interests of Investors in
order to structure a program fair to the Investors.  In addition, the Managing
General Partner believes the interests of the Investors were protected in a
number of other ways described under "Fairness of the Proposals," including
retention of independent Appraisers.  The Managing General Partner believes
that many of the benefits which might be obtained through retention of such a
representative are present by virtue of the use of three Appraisers, rather
than




                                      89
<PAGE>   106
one Appraiser, and by asking the Appraisers to determine the "fair market
value" of each Partnership's Property Interests.  If an independent
representative had been hired, there is a high likelihood that the
representative would have retained a single appraiser to value the oil and gas
assets to be sold.  By virtue of the Special Transactions Committee choosing
the higher of the two values on a Partnership-by-Partnership basis, determined
by two different types of Appraisers, it is believed that many of the elements
of an auction and negotiation were present in the method of setting the value
for purchase of Partnership assets.

BENEFITS TO THE MANAGING GENERAL PARTNER OF UNDEVELOPED RESERVES

         The conflicts of interest are heightened as to those 18 Partnerships
formed in the fourth quarter of 1986, the first three quarters of 1987, and
between the fourth quarter of 1992 and the second quarter of 1994,  that have a
majority of their reserves in the non-producing category.  If these Property
Interests are acquired by the Managing General Partner and it spends capital to
develop undeveloped reserves, the Managing General Partner will benefit from
this activity, possibly to a greater extent than the value given to such
undeveloped reserves.

                           FIDUCIARY RESPONSIBILITY

MANAGING GENERAL PARTNER OF THE PARTNERSHIPS

         Under Texas partnership law, the Managing General Partner is
accountable to the Partnerships as a fiduciary and is required to exercise good
faith and integrity in all its dealings in each Partnership's affairs.  The
partnership agreements generally provide that neither the Managing General
Partner nor any of its affiliates performing services on behalf of the
Partnerships will be liable to the Partnerships or any of the Investors for any
conduct by any such person performed in good faith pursuant to authority
granted to such person by the partnership agreements, or in accordance with its
provisions, and any manner reasonably believed by such person to be within the
scope of authority granted to such person and in the best interests of the
Partnerships, provided that such conduct did not constitute negligence,
misconduct or a breach of fiduciary obligations to the Investors or the
Partnerships.  As a result, Investors might have a more limited right of action
in certain circumstances than they would have in the absence of such provisions
in the partnership agreements.

         Under the partnerships agreements of the Partnerships, the Managing
General Partner is essentially granted the full and exclusive power and
authority to control and manage the Partnerships and the Investors are granted
various rights and powers in accordance with Texas partnership law with respect
to, among others, removal of general partners, dissolution, amendment, meetings
and voting rights.  Further, under Texas partnership law, a limited partner may
bring a derivative action on behalf of the partnership if all of the general
partners with authority to do so have refused to bring the action or if an
effort to cause those general partners to bring such an action is likely to
fail.

         In connection with the concurrent Proposals for sale of substantially
all of the assets of 63 Partnerships to the Company and the subsequent

shares requirement.  Eligible Purchasers may purchase shares of Common Stock
with funds in addition to their cash distributions in order to purchase (i) the
minimum round lot of 100 shares, or (ii) additional shares in excess of the
number for which their cash distribution will be applied, subject to prorata
limitations in the event of oversubscription.  No fractional shares will be
sold.

next whole share.  Any remaining shares will be sold on a prorata basis based
on the number of shares such subscribers wish to purchase.

REVOCATION

         Eligible Purchasers may revoke their subscriptions to purchase Shares
offered hereby at any time until the Due Date by delivering or faxing a letter
so stating or a later dated proxy, either of which must be signed by all

Texas 77060, fax number (281) 874-2818; Attention:  Investor Relations
Department.

OFFERS TO THIRD PARTIES

         In the event this Offering is not fully subscribed by Eligible
Purchasers, the Company may  offer any remaining Shares from time to time to
third parties including, but not limited to, underwriters and institutional
investors.  Specific terms of the offer for the unsubscribed Shares of Common
Stock in respect of which this Prospectus is being delivered will be set forth
in one or more accompanying prospectus supplements.  Such prospectus
supplement(s) will set forth, without limitation, the number of shares of
Common Stock and the terms of the offering and sale thereof.

METHOD OF PURCHASE

         In addition to this Joint Proxy Statement/Prospectus, Investors are
being provided with (i) the relevant Partnership Supplement relating to the
Proposal before their Partnership, (ii) a proxy upon which to vote regarding
the Proposal, and (iii) a Subscription Agreement by which Investors can
purchase shares of the Common Stock offered hereby contingent upon their
becoming Eligible Purchasers.  In order to purchase shares of Common Stock
offered hereby, a Subscription Agreement must be returned.  If a Subscription
Agreement is not returned, an Investor will receive the cash distribution.
Provided their cash distribution is more than the amount required to purchase
the minimum number of shares, Investors may indicate on the Subscription
Agreement that they elect to (i) apply all of their cash distribution to
purchase shares of Common Stock rounded down to the nearest whole share
(fractional shares will be paid in cash), (ii) apply all of their cash
distribution toward the purchase of a designated number of shares of Common
Stock for an amount in excess of their cash distribution for which additional
consideration will be paid to the Company, (iii) apply all of their cash
distribution plus an additional designated dollar amount toward the purchase of
shares of Common Stock, or (iv) purchase shares of Common Stock with a
designated dollar amount or percentage of their cash distribution and receive
the remainder of their distribution in cash.  An Eligible Purchaser whose cash
distribution is less than the amount required to purchase the minimum 100
shares may elect to apply all of his cash distribution towards the minimum
purchase of 100 shares, or a designated number in excess




                                      93
<PAGE>   110
thereof, in either case additional consideration will be paid to the Company.
A second Subscription Agreement will be sent to Eligible Purchasers accompanied
by the Prospectus Supplement advising as to which Partnerships approved the
Proposals.  Eligible Purchasers may subscribe, or revoke their previous
subscription, to purchase shares of the Common Stock offered hereby  from the
date of this Prospectus until the Due Date, unless earlier terminated or
extended by the Company.

         In the event Eligible Purchasers chose to apply all of their cash
distribution to purchase shares of Common Stock and such distribution is more
than the purchase price required to purchase a round lot of 100 shares, such
Eligible Purchasers will receive that number of shares of Common Stock rounded
down to the nearest whole share as can be purchased for such amount.  If such
Eligible Purchaser elects to purchase shares of Common Stock in addition to the
number of shares purchasable with his or her cash distribution, the Eligible
Purchaser will receive a request from the Company for the additional required
purchase price.  If the additional purchase price is not received by the Due
Date, the Company will deem the Eligible Purchaser's subscription for
additional shares revoked.  Upon receipt of the remaining purchase price in the
form of a personal check, a certificate or certificates representing such
shares of Common Stock will be issued on the Closing Date and registered in the
name of or for the account of the Eligible Purchaser.

         In the event an Eligible Purchaser subscribes for the minimum purchase
of 100 shares of Common Stock and his or her cash distribution is less than the
required purchase price for such shares, a request by the Company for the
additional purchase price required will be sent to such Eligible Purchaser.  If
the additional purchase price is not received by the Due Date, the Eligible
Purchaser's subscription will be deemed revoked and the cash distribution will
be sent to such Eligible Purchaser.

           MATERIAL FEDERAL INCOME TAX CONSIDERATIONS OF ELECTING TO
                      RECEIVE COMMON STOCK IN LIEU OF CASH
                          UPON PARTNERSHIP LIQUIDATION

         The following is a discussion of the material federal income tax
consequences that are generally applicable under existing United States federal
income tax law to Investors that elect to subscribe to shares of Common Stock
in lieu of receiving all or some of their Partnership liquidating distribution.
The discussion is based upon the Code, Treasury Regulations, judicial
authority, published positions of the Service and other applicable authorities,
all as in effect on the date hereof and all of which is subject to change,
possibly retroactively.  This discussion does not address all aspects of
federal income taxation that may be material or relevant to particular
investors in light of their own personal circumstances.  This discussion does
not address any aspect of state, local or foreign tax law or any aspect of tax
law solely applicable to qualified plans and individual retirement accounts,
all as defined under the Code, and is not applicable 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
proceedings, or an investment company, financial institution or insurance
company.  No ruling has been sought from the Service in connection with tax
aspects related to the proposed transactions.  Accordingly, no assurance can be
given that the Service will not take a position contrary to any of the tax
aspects described below.

PAYMENT FOR STOCK WITH LIQUIDATING DISTRIBUTION

         As currently proposed, Investors that subscribe for Common Stock
pursuant to this Offering will not actually receive some or all of the cash
liquidating distribution of their Partnership interest to which they otherwise
would be entitled.  The amount of any cash liquidating distribution they
actually receive depends upon the purchase price to be paid for the shares they
elect to and are entitled to receive pursuant to the terms of this Offering.
For federal income tax purposes, Investors subscribing for shares of Common
Stock will be treated as though they had purchased those shares for cash, even
though they never had actual possession of the cash used to acquire the shares.
Additionally, the fact that such Investors elect to acquire shares rather than
receive cash in liquidation of their Partnership interests will not affect the
federal income tax consequences attending the liquidation of their Partnership
interests.  Investors should refer to Federal Income Tax Consequences of
Adoption of the Proposals in this Prospectus for a discussion of the federal
income tax consequences related to the liquidation of their Partnership
interests.  Because the purchase of shares of Common Stock will reduce the cash
received by the Investor on the Partnership liquidation, to the extent that
Investors owe federal income tax as a result of the liquidation, they may not
receive sufficient cash to pay some or all of any tax they may owe on the
liquidation.  Such Investors owing tax as a result of the liquidation will have
to pay such tax from sources other than distributions from their Partnership.

STOCK PURCHASE WITH CASH LIQUIDATING DISTRIBUTION

         Subject to unusual individual circumstances of an Investor, Investors
that elect to purchase shares of Common Stock will hold such shares as capital
assets and will have a holding period that begins on the day they acquire such
shares.

PARTNERS THAT ARE TAX EXEMPT PLANS

         Investors in SEMPAP or SEPP Partnerships that are Tax Exempt Plans
that elect to subscribe for Common Stock and that are not subject to the debt
financing rules, are not expected to realize any current tax consequences upon
liquidation of their Partnership or the acquisition of Common Stock.  See
"Federal Income Tax Consequences of Adoption of the Proposals--Tax Treatment of
Tax Exempt Plans."

         The above prices for 1996 and 1997 have been revised to reflect a 10%
Common Stock dividend declared and paid in October 1997.  On July 24, 1998, the
last reported sale price for the Common Stock on the New York Stock Exchange
was $11.94 per share.

         Since the Company's inception, no cash dividends have been declared on
its Common Stock, and the Company does not expect to declare cash dividends in
the foreseeable future.  The Company currently intends to continue a policy of
using retained earnings for expansion of its business.  Under its current
credit arrangements, the Company may not declare cash dividends on its Common
Stock that exceed $2.0 million in any fiscal year.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
 
   
     The following unaudited pro forma consolidated statements of income for the
year ended December 31, 1997 and for the six months ended June 30, 1998, and the
unaudited pro forma consolidated balance sheets as of June 30, 1998
(collectively, the "Pro Forma Financial Statements") are based on the historical
consolidated financial statements of the Company, the historical combined
financial statements of all the Partnerships (See Note 1 to the Combined
Financial Statements of the Partnerships for a listing of the 63 Partnerships
whose oil and gas assets are proposed to be acquired) under the 100% Case and
the 50% Case scenarios, and the historical statements of revenues and direct
operating expenses of the oil and gas properties acquired from Sonat, adjusted
to give effect to the Partnership Properties Acquisition and the Sonat
Properties Acquisition and borrowings under the New Credit Facility under the
scenarios described below.
    
 
   
     The Company has no reason to believe that any Partnership or group of
Partnerships is more or less likely than any other to withhold approval of the
Proposals to sell their assets and liquidate their respective Partnerships.
Accordingly the Partnership Properties Acquisition adjustments in the 100% Case
Pro Forma Financial Statements assume that all 63 Partnerships will approve
their respective Proposals. However, for purposes of presenting a pro forma case
should there be only partial approval of the Proposals, the 50% Case shows the
effect of approval of the Proposals only by those 48 Partnerships with the
lowest levels of net cash provided by operating activities, selected in
ascending order until the group of such Partnerships collectively represents
approximately 50% of the combined net cash provided by operating activities for
the six months ended June 30, 1998 of all 63 Partnerships.
    
 
   
     The unaudited pro forma consolidated statements of income for the year
ended December 31, 1997 and for the six months ended June 30, 1998 give effect
to the Acquisitions and the borrowings under the New Credit Facility as if they
had occurred as of January 1, 1997. The unaudited pro forma consolidated balance
sheets give effect to the Acquisitions and the borrowings under the New Credit
Facility as if they had occurred as of June 30, 1998. The Pro Forma Financial
Statements assume (i) the Partnership Properties Acquisition (100% Case) is
consummated for (a) all Cash ("All Cash") or (b) cash and 2.5 million shares of
Common Stock ("Equity/Cash") at an assumed price of $18 per share, or the
Partnership Properties Acquisition (50% Case) is consummated for (a) all cash or
(b) 2.1 million shares of Common Stock ("All Equity") at an assumed price of $18
per share and (ii) the Sonat Properties Acquisition is consummated for all cash.
The Pro Forma Financial Statements present the following Acquisitions and
financing scenarios:
    
 
          a) 100% Case All Cash Partnership Properties Acquisition, the Sonat
     Properties Acquisition and borrowings under the New Credit Facility;
 
          b) 100% Case Equity/Cash Partnership Properties Acquisition, the Sonat
     Properties Acquisition and borrowings under the New Credit Facility;
 
          c) 50% Case All Cash Partnership Properties Acquisition, the Sonat
     Properties Acquisition and borrowings under the New Credit Facility; and
 
          d) 50% Case All Equity Partnership Properties Acquisition, the Sonat
     Properties Acquisition and borrowings under the New Credit Facility.
 
     The pro forma adjustments are described in the accompanying Notes to
Unaudited Pro Forma Consolidated Financial Statements and are based upon
available information and certain assumptions that Management believes are
reasonable.
 
   
     The Pro Forma Financial Statements do not purport to represent what the
Company's results of operations or financial condition would actually have been
had the Acquisitions in fact occurred on such dates or to project the Company's
results of operations or financial condition for any future date or period. The
Pro Forma Financial Statements should be read in conjunction with "Management's
Discussion and Analysis of Financial Condition and Results of Operations", the
Consolidated Financial Statements of the Company and related notes thereto, the
Combined Financial Statements of the Partnerships and related notes thereto, and
the Historical Statements of Revenues and Direct Operating Expenses of the Sonat
Properties Acquisition and related notes thereto all included elsewhere in this
Joint Proxy Statement/Prospectus.

(h)  Represents the elimination of intercompany accounts receivables due from
     the Partnerships and payables due to the Partnerships.
 
   
(i)  Under the 100% Case - Equity/Cash and the 50% Case - All Equity, this
     reflects the issuance of 2.5 million and 2.1 million shares, respectively
     of Common Stock ($0.01 par value) at an assumed price of $18 per share.
    
 
(j)  The pro forma adjustments to deferred charges and cash represents the costs
     incurred to establish the New Credit Facility.
 
(k)  Represents the elimination of the Partnerships' historical asset and
     liability balances (excluding the Company's ownership interests) and
     Partners' Capital.
 
(l)  For purposes of calculating the ratio of earnings to fixed charges, fixed
     charges include interest expense, capitalized interest, amortization of
     debt issuance costs and that portion of non-capitalized rental expense
     deemed to be the equivalent to interest. Earnings represents income before
     income taxes from continuing operations before fixed charges. The Company's
     Management uses the ratio of earnings to fixed charges to determine the
     extent to which the Company's earnings are adequate to cover fixed charges
     (as defined).
 
(m)  The "Supplemental Cash Flow Information" for each scenario presented was
     calculated as follows:
 
         (i) Pro forma operating cash flows was calculated by adding to the
             Company's historical operating cash flows the pro forma incremental
             increase in net income and depreciation, depletion, and
             amortization resulting from the Acquisitions.
 
        (ii) Pro forma investing cash flows was calculated by adding to the
             Company's historical investing cash flows the cash outlay, if any,
             required to consummate the Acquisitions.
 
        (iii) Pro forma financing cash flows was calculated by adding to the
              Company's historical financing cash flows the necessary funds
              required to be borrowed under the Company's New Credit Facility to
              consummate the Acquisitions.
 
   
(n)  Represents the use of available cash to partially fund the cash outlay
     required for the Acquisitions.

(b)  As of January 1, 1994, the Company changed its revenue recognition policy
     for earned interests. Accordingly, for 1997, 1996, 1995, and 1994, and for
     the six months ended June 30, 1998 and 1997 "Fees and Earned Interests"
     does not include earned interests. In 1994, the Company recognized a charge

     of Financial Accounting Standards No. 128, "Earnings per Share" (see Note 2
     to the Consolidated Financial Statements).
 
(d)  On a pro forma basis, assuming the 1994 change in accounting principle is
     applied retroactively, basic and diluted earnings per share would have been
     $0.51 for 1994 and $0.60 and $0.57, respectively, for 1993.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

         The following discussion should be read in conjunction with the
Company's Consolidated Financial Statements and the related notes thereto set
forth elsewhere in this Joint Proxy Statement/Prospectus.

GENERAL

   
         The Company's principal corporate objectives are the accumulation of
crude oil and natural gas reserves for production and sale and the enhancement
of the net present value of those reserves.  The Company was formed in 1979
and, from 1985 to 1991, grew primarily through the acquisition of producing
properties funded through limited partnership financing.  Commencing in 1991,
the Company began to emphasize the addition of reserves through increased
development and exploration drilling activity. This emphasis on development and
exploration drilling has led to additions of increasing quantities of reserves
in each of the years 1995 through 1997, and in the first six months of 1998.
The Company's revenues are primarily comprised of oil and gas sales
attributable to properties in which the Company owns a direct or indirect
interest.
    

         Proved Oil and Gas Reserves

   
         In 1997, the Company's proved natural gas reserves increased 88.5 Bcf
(39%) and its proved oil reserves increased 2,374,609 barrels (43%) or a total
of 102.8 Bcfe (40%).  From 1995 to 1996, the Company's proved natural gas
reserves increased 82.2 Bcf (57%) and its proved oil reserves increased 62,328
barrels (1%).  The Company's additions to proved reserves from its development
and exploration program were 120.2 Bcfe in 1997, 118.2 Bcfe in 1996 and 72.4
Bcfe in 1995.  A substantial portion of these reserves are proved undeveloped
reserves comprising 144.6 Bcfe (40%) of total proved reserves at year-end 1997,
101.5 Bcfe (39%) of total proved reserves at year-end 1996 and 74.7 Bcfe (42%)
of total proved reserves at year-end 1995.  This reflects the emphasis on
development and exploration activities.

         Proved developed reserves additions in 1997 resulted from drilling
activity (which also increased undeveloped reserves) and the purchases of
minerals in place, offset somewhat by revisions of previous estimates.  The
change in the Standardized Measure of Discounted Future Net Cash Flows (see
Supplemental Information to the Company's Consolidated Financial Statements and
in the Estimated Present Value of Proved Reserves (see "Business and Properties
- --Oil and Gas Reserves") from year-end 1996 to year-end 1997 is also due to the
addition of reserves through the Company's drilling activity (primarily in the
AWP Olmos Field and the Austin Chalk trend) and the purchases of minerals in
place (primarily in the AWP Olmos Field), offset by revisions of previous
estimates and by the 38% decrease in year-end 1997 natural gas prices ($2.78
per Mcf at year-end 1997 versus $4.47 per Mcf at year-end 1996), and to the 34%
decrease in year-end 1997 oil prices ($15.76 per Bbl at year-end 1997, compared
to $23.75 per Bbl the prior year).  While the Company's total proved reserves
quantities at year-end 1997 increased by 40% over reserves quantities the prior
year, the PV-10 Value of those reserves decreased 26% from the PV-10 Value at
year-end 1996.  This decrease was due almost entirely to pricing declines at
year-end 1997 as compared to year-end 1996, which more than offset the 40% Bcfe
increase in reserve quantities.
    

         Under Commission guidelines, the Company's estimates of cash flows
from proved reserves are made using oil and gas sales prices and operating
costs in effect as of the dates of such estimates and are


                                      115
<PAGE>   132
   
held constant throughout the life of the properties, except where such
guidelines permit alternative treatment, including, in the case of gas
contracts, the use of fixed and determinable contractual price escalations.
The $2.78 per Mcf and the $15.76 per Bbl used to calculate the PV-10 Value at
year-end 1997 were the Company's sales prices in effect as of the year-end
1997.  Such prices, however, may not be indicative of future sales prices
ultimately received.  As of June 30, 1998, gas prices had declined slightly to
$2.59 per Mcf and oil prices had declined to $12.32 per barrel.  This price
decline was the primary cause for the decrease in the Company's ceiling test
cushion from $60.1 million at year- end 1997 to an estimated $23.4 million at
June 30, 1998.  See "Risk Factors--Risks of Investment in the
Company--Volatility of Oil and Gas Prices and Market; Ceiling Test Writedowns."
    

LIQUIDITY AND CAPITAL RESOURCES

   
         During the first six months of 1998, the Company relied upon its
internally generated cash flows, along with $56.1 million of bank borrowings to
fund its capital expenditures.  Cash and working capital for the remainder of
1998 are expected to be provided through internally generated cash flows, bank
borrowings and debt or equity financings.  During 1997, the Company relied upon
net proceeds from its $115.0 million Convertible Notes and its internally
generated cash flows, along with $7.9 million of bank borrowings.
    

         Net Cash Provided by Operating Activities

   
         For the six month period ended June 30, 1998, net cash provided by
operating activities decreased 16% to $25.5 million, as compared to $30.3
million during the first six months of 1997.  The 1998 decrease of $4.8 million
was primarily due to a decrease in cash flows from oil and gas sales, which
decreased by $0.8 million (3%), exclusive of the non-cash amortization of
deferred revenues associated with the Company's volumetric production payment,
along with the $1.7 million decrease in interest income and the $0.6 million
increase in interest expense, a result of having expended all the net proceeds
of the $115.0 million Convertible Notes offering, as well as the $0.7 million
increase in production costs which relates to the increase in production
volumes.  The decrease in oil and gas sales was due to substantially lower
product prices, somewhat offset by increased production volumes, as discussed
below.

         In 1997, 1996 and 1995, the Company's operating activities provided
net cash of $55.3 million, $37.1 million and $14.4 million, respectively.
These increases were primarily due to increased production volumes, as
discussed below.  The 1997 increase of $18.2 million was primarily due to an
increase in cash flows from oil and gas sales, which increased $16.5 million
(32%), exclusive of the non-cash amortization of deferred revenues associated
with the Company's volumetric production payment.  The 1996 increase of $22.7
million in net cash from operations was primarily due to the cash flows from
oil and gas sales, which increased $30.4 million (146%), exclusive of the
non-cash amortization of deferred revenues associated with the Company's
volumetric production payment, partially offset by a $1.6 million increase in
oil and gas production costs, a $1.1 million increase in general and
administrative costs, plus changes to assets and liabilities and deferred
income taxes.  These 1997 and 1996 increases in oil and gas sales were
primarily the result of the Company's increased drilling activity, as well as
its being affected by product price fluctuations.

         Sale of Convertible Notes

   
         In November 1996, the Company issued $115.0 million of the Convertible
Notes in a public offering.  Proceeds of the offering were used to repay all of
the Company's bank borrowings ($33.1 million on November 25, 1996) and,
together with internally generated cash flows, to fund capital expenditures and
working capital needs through 1997.  The principal terms of these Convertible
Notes are more fully described in Note 4 to the Company's Consolidated
Financial Statements included elsewhere in this Joint Proxy
Statement/Prospectus.
    

         Credit Facilities

   
         At June 30, 1998, the Company had outstanding borrowings of $64.0
million under its Credit Facilities.  Such Credit Facilities consisted of a
$100.0 million revolving line of credit with an $80.0 million borrowing base
and a $7.0 million revolving line of credit with a $5.1 million borrowing base.

         On August 18, 1998, the Company closed on the New Credit Facility,
consisting of a $250.0 million revolving line of credit, of which Bank One,
Texas, National Association, the lead bank, has committed $37.5 million and has
syndicated the balance with a group of nine other banks.  The New Credit
Facility is subject to an initial borrowing base of $170.0 million.  However,
an additional $30.0 million will be added to this borrowing base upon
consummation of the Partnership Properties Acquisition.  As of September 1,
1998, $19.2 million of the $170.0 million borrowing base was available to the
Company.  The New Credit Facility replaces all of the Company's prior bank
credit facilities.  The borrowing base will be redetermined semi-annually on
the basis of reserve reports and other information available to the lenders.
In addition, the lenders may, at their discretion, make a redetermination of
the borrowing base at any time including in connection with a request by the
Company to redetermine the borrowing base, the incurrence of additional debt
and the sale or transfer of properties by the Company.

         Borrowings under the New Credit Facility bear interest, at the option
of the Company, either at (i) the lead bank's prime rate, currently 8.5%, or
(ii) adjusted LIBOR plus the applicable margin, which increases as the level of
outstanding debt increases.  The terms of the New Credit Facility include
restrictions such as limitations on debt obligations, certain liens, dividends
(not to exceed $2.0 million annually), a $15.0 million limit on repurchases by
the Company of its Common Stock, as well requirements as to maintenance of
certain minimum financial ratios (principally pertaining to working capital,
debt and equity ratios).

         Debt Maturities

         The New Credit Facility extends until August 18, 2002.  The Company's
$115.0 million Convertible Notes mature November 15, 2006.
    

         Working Capital

   
         The Company's working capital increased in the first six months of
1998, from $1.5 million at December 31, 1997, to $10.3 million at June 30,
1998.  This increase is primarily the result of approximately $8.8 million in
cash previously escrowed on the Sonat Properties (originally drawn on the
revolving line of credit) being refunded to the Company and increasing cash and
cash equivalents at period end.
    





                                      117
<PAGE>   134
   
         Due to the nature of the Company's business highlighted above, the
individual components of its working capital fluctuate considerably from period
to period.  The Company incurs significant working capital requirements in
connection with its role as operator of approximately 650 wells, its drilling
programs and the management of affiliated partnerships.  In this capacity, the
Company is responsible for certain day-to-day cash management, including the
collection and disbursement of oil and gas revenues and related expenses.
    

         Common Stock Repurchase Program

         In March 1997, the Company's Board of Directors approved a Common
Stock repurchase program for up to $20.0 million of the Company's Common Stock
and subsequently extended the program through June 30, 1998.  Purchases of
shares were made in the open market.  Under this program, through June 30,
1998, the Company used $9.35 million of working capital to acquire 435,274
shares at an average cost of $21.47 per share.  Although this program was
completed at June 30, 1998, the Board of Directors approved a new repurchase
program on July 23, 1998 for up to $10.0 million of the Company's common stock.

         Common Stock Dividend

         In October 1997, the Company declared a 10% stock dividend to
shareholders of record.  The transaction was valued based on the closing price
($28.8125) of the Company's Common Stock on the New York Stock Exchange on
October 1, 1997.  As a result of the issuance of 1,494,606 shares of the
Company's Common Stock as a dividend, retained earnings were reduced by
approximately $43.1 million, with the Common Stock and additional paid-in
capital account increased by the same amount.

         Capital Expenditures

   
         Capital expenditures for property, plant, and equipment during the
first six months of 1998 were $70.0 million.  These capital expenditures
included:  (a) $45.7 million of drilling costs, both development (25 wells) and
exploratory (5 wells) (primarily in the AWP Olmos Field and Austin Chalk
trend), (b) $14.3 million of prospect costs (principally prospect leasehold,
seismic and geological costs of unproved prospects for the Company's account),
(c) $1.3 million invested in foreign business opportunities in New Zealand
(approximately $0.6 million), in Venezuela (approximately $0.3 million) and
Russia (approximately $0.4 million), (d) $1.5 million spent on field facilities
and production equipment and (e) $4.0 million on producing property
acquisitions, with the remainder spent primarily for computer equipment and
furniture and fixtures.

         The consummation of the Acquisitions, estimated at a capital cost of
$145.8 million, could impact the anticipated timing and nature of the remaining
1998 capital expenditures.  The Company has budgeted capital expenditures of
$241.5 million for 1998, comprised of $145.8 million for acquisitions and $95.7
million for development and exploration.  The Company currently plans to
participate in the drilling of 67 gross wells this year, compared to 182 wells
in 1997.  Approximately 59% of the $95.7 million is targeted for the continued
development of the Company's two core areas.  In the remaining six months of
1998, the Company expects capital expenditures to be approximately $171.5
million, including investments in all areas in which investments were made
during the first six months of the year as described above, with a particular
focus on the acquisition of producing properties.  The Company currently plans
to participate in the drilling of 77 gross wells this year, compared to 182
wells in 1997.  Through June 30, 1998, the
    




                                      118
<PAGE>   135
   
Company has participated in drilling 55 wells (44 development and 11
exploratory wells with 38 development and 5 exploratory successes) at a capital
cost of approximately $45.7 million to the Company.  The steady growth in the
Company's unproved property account which is not being amortized is indicative
of the Company's continued focus on drilling, as the Company acquires prospect
acreage, and continued foreign activities.

         The Company believes that 1998's anticipated internally generated cash
flows (expected to increase as the Company's production base increases as a
result of its drilling program and the Acquisitions), together with bank
borrowings will be sufficient to finance the costs associated with its
currently budgeted 1998 capital expenditures.

         The Company's capital expenditures were approximately $132.0 million,
$91.5 million and $40.0 million for 1997, 1996 and 1995, respectively.  The
1997 capital expenditures included (a) $90.3 million (68% of 1997 capital
expenditures) on development drilling (primarily in the AWP Olmos Field and
Austin Chalk trend), (b) $10.7 million (8%) on exploratory drilling, (c) $18.4
million (14%) on domestic prospect costs (principally prospect leasehold,
seismic and geological costs of unproven prospects for the Company's account),
(d) the purchase of $8.4 million (6%) of producing property interests, $7.1
million from third parties (primarily in the AWP Olmos Field), along with the
purchase of $1.3 million of limited partner interests in previously formed
partnerships through the right of presentment arrangement provided in those
partnerships, (e) $3.2 million (3%) invested in foreign business opportunities
in Russia ($0.7 million), Venezuela ($0.8 million) and New Zealand ($1.7
million), as described in Note 8 to the Company's Consolidated Financial
Statements and (f) $0.9 million (1%) spent on fixed assets.  In 1997, the
Company participated in drilling 182 wells (167 development and 15 exploratory
wells with 159 development and 15 exploratory successes).  The steady growth in
the Company's unproved property account ($41.8 million), which is not being
amortized, is indicative of the shift to a focus on drilling activity as the
Company acquires prospect acreage, including $3.2 million of capital
expenditures in 1997 made in relation to the Company's foreign business
opportunities, as described above.

         Sonat Properties Acquisition

         On July 2, 1998, the Company entered into an agreement to purchase
from Sonat, effective April 1, 1998, certain producing oil and gas properties
located in the Texas and Louisiana Austin Chalk trend for approximately $87.6
million in cash.  As of April 1, 1998, estimated proved reserves for the Sonat
Properties were 91.1 Bcfe, of which approximately 56% was natural gas, with
1997 production of 22.0 Bcfe, of which approximately 51% was natural gas.  The
properties include 156 producing oil and natural gas wells in the Brookeland
Field in Southeast Texas and the Masters Creed Field in Western Louisiana, 21
saltwater disposal wells, a 20% interest in two natural gas plants, associated
production facilities and working interests in approximately 200,000
undeveloped net acres containing more than 50 drilling locations.  The company
will become operator of 113 of the 156 wells.  The two gas plants have combined
capacity of 250.0 Mmcfe per day, and in 1997 had operating cash flow of $2.8
million.  UPRC is the operator of both plants.  Certain other owners of oil and
gas interests in the Sonat Properties have the preferential right to acquire
certain additional interests which, if acquired, would reduce the interest
acquired by the Company.  The acquisition is expected to close in August 1998.

         Partnership Programs

   
         Since late 1993, the Company has offered interests in private
partnerships formed to drill for oil and gas.  During the second quarter of
1998, the Company formed a drilling partnership with subscriptions of
approximately $3.5 million.  During 1997, the Company formed three drilling
partnerships with subscriptions of approximately $16.8 million and in 1996
formed three partnerships with subscriptions of approximately $22.0 million.
The Company anticipates that it will continue to offer such drilling
partnerships for the foreseeable future.

         At June 30, 1998, limited partnership formation and marketing costs
(which under the current drilling partnership offerings are borne by the
Company as part of the Company's general partner contribution) amounted to $0.8
million, an increase of $0.5 million when compared with the balance at December
31, 1997.

         During 1996, the limited partners in 18 partnerships, which had been
in operation over nine years and had produced a substantial majority of their
reserves, voted to sell their remaining properties and liquidate the limited
partnerships.  Of these partnerships, 10 were the earliest public income
partnerships (formed in 1984 to 1986) and were liquidated in 1996, and in early
1997 eight private drilling partnerships (formed in 1979 to 1985) were
liquidated.  Similarly, during 1997, the limited partners in an additional 11
partnerships (formed in 1990 and 1991) voted to sell their properties and
liquidate the limited partnerships, which liquidation occurred in June 1998.
    

         Other Financing Activities

   
         During the third quarter of 1995, the Company sold 5.75 million shares
of Common Stock in a public offering at $8.50 per share, with net proceeds of
$45.7 million principally used to repay outstanding indebtedness and finance
the Company's development and exploration activities.  In addition, as
described in Note 4 to the Company's Consolidated Financial Statements included
herein, following the Company's July 1996 announcement of their redemption, the
Debentures were converted by their holders into 2.34 million shares of the
Company's Common Stock.  As a result of this conversion, the Company's
stockholders' equity increased approximately $27.0 million.

RESULTS OF OPERATIONS -- SIX MONTHS ENDED JUNE 30, 1998 AND 1997
    

         Revenues

   
         The Company's revenues decreased 8% during the first six months of
1998 as compared to the same period in 1997, due primarily to the decrease in
oil and gas sales, a result of lower commodity prices, and the decrease in
interest income, resulting from expenditure of the net proceeds from the
Convertible Notes by year-end 1997.

         Oil and Gas Sales.  Oil and gas sales decreased 3% to $31.5 million in
the first six months of 1998, compared to $32.4 million for the comparable
period in 1997.  The 20% increase in natural gas production and the 18%
increase in oil production were primarily the result of production from recent
drilling activity, most notably from one of the Company's two primary
development areas, the Austin Chalk trend.  The company's other primary
development area, the AWP Olmost Field, experiences a slight increase (3%) in
equivalent production when compared to 1997.  The Company's net sales volume
(including the volumetric production payment volumes) of in the first six
months of 1998 increased by 19% or 2.3 Bcfe
    





                                      120
<PAGE>   137
   
over volumes in the comparable 1997 period.  The increases in volume were more
than offset by a 36% decrease in oil prices and a 15% decrease in gas prices
received between the two periods, as highlighted in the table below.

         The elements of the Company's $1.0 million decrease in oil and gas
sales during the first six months of 1998 included:  (1) volume increases that
added $5.1 million of sales from a 2.0 Bcf increase in gas sales volumes and
$1.1 million of increased sales from the 58,800 barrel increase in oil sales
volumes and (2) price variances that had a $7.2 million unfavorable impact on
sales due to the decrease in average oil prices received  ($4.6 million), and a
decrease in average oil prices received ($2.6 million).  Oil and gas sales for
the first six months of 1998 from the AWP Olmos Field were $17.2 million ($20.3
million in 1997) from 7.8 Bcfe of net sales volumes (7.6 Bcfe in 1997) for an
increase of 0.2 Bcfe, while the Austin Chalk trend generated oil and gas sales
of $8.9 million ($5.5 million in 1997) from 3.9 Bcfe of net sales volume (2.1
Bcfe in 1997) for an increase of 1.8 Bcfe.

         Revenues from oil and gas sales comprised 96% and 91%, respectively,
of total revenues for the first six months of 1998 and 1997.  The majority (85%
and 81%, respectively) of these revenues were derived from the sale of the
Company's gas production.  The Company expects oil and gas production to
continue to increase due to both of the addition of oil and gas reserves
through the Company's active drilling program and from the Acquisitions.
    

         The following table provides additional information regarding the
Company's oil and gas sales.

         Costs and Expenses

   
         General and administrative expenses for the first six months of 1998
increased by approximately $72,000, or 4%, when compared to the same period in
1997.  This increase in costs reflects the increase in the Company's
activities.  However, the Company's general and administrative expenses per
Mcfe produced decreased by 13% from $0.15 per Mcfe produced for the first six
months of 1997 to $0.13 per Mcfe produced for the comparable period in 1998.
Supervision fees netted from general and administrative expenses for the first
six months of 1998 and 1997 were $1.4 million and $1.3 million, respectively.

         Depreciation, depletion, and amortization ("DD&A") increased 26%
(approximately $2.9 million) for the first six months of 1998, primarily due to
the Company's reserves additions and associated costs
    



                                      121
<PAGE>   138
   
and to the related sale of increased quantities of oil and gas produced
therefrom.  The Company's DD&A rate per Mcfe of production has increased from
$0.93 per Mcfe produced in the 1997 period to $0.98 per Mcfe produced in the
1998 period, reflecting increases in the per unit cost of reserve additions.

         Production costs per Mcfe decreased from $0.35 per Mcfe produced in
the 1997 period to $0.34 per Mcfe produced in the 1998 period.  Primarily due
to the 19% increase in production volumes, oil and gas production costs
increased 17% (approximately $0.7 million) in the first six months of 1998 when
compared to the first six months of 1997.  Supervision fees netted from
production costs for the first six months of 1998 and 1997 were $1.4 million
and $1.3 million, respectively.

         Interest expense in the first six months of 1998 on the Convertible
Notes, including amortization of debt issuance costs, totaled approximately
$3.8 million (approximately $3.8 million in the 1997 period), while interest
expense on the Existing Credit Facilities, including commitment fees, totaled
$1.1 million ($24,000 in the 1997 period for commitment fees alone) for total
interest payments of $4.8 million  (of which $1.9 million was capitalized).  In
the first six months of 1997, these payments totaled $3.8 million  (of which
$1.4 million was capitalized).  The Company capitalizes that portion of
interest related to its exploration, partnership and foreign business
development activities.  The increase in interest expense in 1998 is
attributable to the increase in interest incurred on the credit amounts
outstanding on its Existing Credit Facilities.
    

         Net Income

   
         Net income of $6.1 million and earnings per share of $0.37 for the
first six months of 1998 were both 44% lower than net income of $10.9 million
and earnings per share of $0.66 in the same period for 1997.  This decrease in
net income primarily reflected the effect of a decrease in oil and gas revenues
as a result of a 36% and 15% decrease in oil and gas prices.

RESULTS OF OPERATIONS -- YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
    

         Revenues

         The Company's revenues in 1997 increased by 32% over revenues in 1996
and by 110% in 1996 over 1995 revenues, principally due to increases in oil and
gas production volumes and gas prices.

   
         Oil and Gas Sales.  The Company's net sales volumes in 1997 (including
the volumetric production payment associated with each year's production)
increased by 31% (6.0 Bcfe) over net sales volumes in 1996, while 1996 net
sales volumes increased by 74% (8.3 Bcfe) over net sales volumes in 1995.  Oil
and gas sales in 1997 increased by 31% ($16.2 million) over those revenues for
1996, while in 1996 those revenues increased by 134% ($30.2 million) over oil
and gas sales in 1995.  Average prices for oil increased from $15.66 per Bbl in
1995 to $19.82 per Bbl in 1996 and then decreased to $17.59 per Bbl in 1997,
while average gas prices increased from $1.77 per Mcf in 1995 to $2.57 per Mcf
in 1996 and to $2.68 per Mcf in 1997.  The Company's $16.2 million increase in
oil and gas sales during 1997 was comprised of volume increases that added
$14.5 million of sales from the 5.7 Bcf increase in gas sales volumes and $1.0
million of sales from the 49,000 barrel increase in oil sales volumes, while
price variances contributed $2.2 million in increased sales from the increase
in average gas prices received, offset somewhat by a $1.5 million decrease in
sales from the decrease in average oil prices received.  The Company's $30.2
million increase in oil and gas sales during 1996 was comprised of volume
increases that
    


                                      122
<PAGE>   139
added $13.8 million of sales from the 7.8 Bcf increase in gas sales volumes and
$1.2 million of sales from the 78,000 barrel increase in oil sales volumes,
while price variances contributed $12.7 million in increased sales from the
increase in average gas prices received and $2.5 million in increased sales
from the increase in average oil prices received.

   
         The increases in oil and gas sales for 1997 and 1996 were primarily
the result of production from the Company's active drilling program, most
notably from the Company's two core areas, the AWP Olmos Field and the Austin
Chalk trend.  The Company's 1997 oil and gas sales from the AWP Olmos Field
were $42.2 million ($29.9 million in 1996) from 15.5 Bcfe of net sales volumes
(11.2 Bcfe in 1996) for an increase of 4.3 Bcfe, while the Austin Chalk trend
generated 1997 oil and gas sales of $12.9 million ($9.4 million in 1996) from
4.9 Bcfe of net sales volumes (3.4 Bcfe in 1996) for an increase of 1.5 Bcfe.
    

         Revenues from oil and gas sales comprised 86%, 87% and 78%,
respectively, of total revenues for 1997, 1996 and 1995.  The majority (83%,
77% and 62%, respectively) of these oil and gas revenues in these periods were
derived from the sale of the Company's gas production.  The Company expects oil
and gas sales to continue to increase as a direct consequence of the addition
of oil and gas reserves through the Company's active drilling program and from
the Acquisitions.

   
    

         Costs and Expenses

   
         General and administrative expenses in 1997 decreased $0.3 million
(4%) from the level of such expenses in 1996, while 1996 general and
administrative expenses increased $1.1 million (21%) over 1995 levels.  The
slight decrease in these costs in 1997 over 1996 reflected the Company's
ability to continue increasing its drilling activity without increasing such
costs in 1997.  The increase in costs in 1996 over 1995 reflected the increase
in the Company's activities.  The Company's general and administrative expenses
per Mcfe produced have decreased in each of the past three years from $0.30 per
Mcfe produced in 1995 to $0.21 per Mcfe produced in 1996 to $0.14 per Mcfe
produced in 1997.  Supervision fees netted from general and administrative
expenses for 1997, 1996 and 1995 were $2.6 million, $2.4 million and $1.9
million, respectively.

         DD&A has steadily increased, primarily due to the Company's reserves
additions and associated costs and to the related sale of increased quantities
of oil and gas produced therefrom.  The Company's DD&A rate per Mcfe of
production was $0.95 in 1997, $0.95 in 1996, and $0.79 in 1995, reflecting
variations in the per unit cost of reserves additions.

         Production costs in 1997 increased $3.0 million (36%) over such
expenses in 1996, while those expenses in 1996 increased $1.6 million (23%)
over 1995.  The increases in each of the periods primarily relate to the
increase in the Company's oil and gas sales volumes.  The Company's production
costs per Mcfe produced were $0.35 in 1997, $0.31 in 1996 and $0.44 in 1995.
As discussed above, the Company's increase in production is primarily through
its drilling activities in the AWP Olmos Field and Austin Chalk trend, where
the Company already has an established operating base.  The increase in
production costs has been partially offset by an exemption in these same fields
from the 7.5% Texas severance tax applicable to gas production from certain
natural gas wells certified to be in tight formations or to be deep wells by
the Texas Railroad Commission.  This exemption in 1996 was a major contributor
in reducing the Company's production costs per Mcfe produced from the 1995 rate
of $0.44 to the 1996 rate of $0.31.  Additionally, commencing September 1,
1996, certain wells certified as "high cost gas" wells are entitled to a
reduction of severance tax based upon a formula amount but not the full
exemption of 7.5% received
    





                                      123
<PAGE>   140
   
on certified wells drilled prior to September 1, 1996.  This tax exemption had
a favorable impact on the Company's production costs during 1996 and 1997,
although under the new rules, the proportionate amount of the exemption was
decreased in the 1997 period, thus contributing to the $0.04 increase in
production costs per Mcfe produced in 1997 when compared to 1996.  Supervision
fees netted from production costs for 1997, 1996 and 1995 were $2.6 million,
$2.4 million and $1.9 million, respectively.

         Interest expense in 1997 on the Convertible Notes, including
amortization of debt issuance costs, totaled $7.5 million, compared to $0.7
million on the Convertible Notes and $1.0 million on the 6.5% Convertible
Subordinated Debentures due 2003 (the "Debentures") in 1996 and $2.0 million on
only the Debentures in 1995, while interest expense on the Credit Facilities,
including commitment fees, totaled $0.1 million ($1.1 million in 1996 and $1.7
million in 1995), for a 1997 total of $7.6 million (of which $2.6 million was
capitalized).  The 1996 total was $2.8 million (of which $2.1 million was
capitalized), while the 1995 total was $3.7 million (of which $2.6 million was
capitalized).  The Company capitalizes a portion of interest related to certain
exploration, partnership and foreign business development activities.  The
increase in interest expense in 1997 is attributable to the larger outstanding
principal amount on the Convertible Notes ($115.0 million) compared to the
Debentures ($28.8 million), offset to some degree by larger outstanding
balances under the Credit Facilities in 1996 and by the $2.4 million in
interest income earned in 1997 on the portion of the net proceeds of the
Convertible Notes invested pending use.  The lower amount of interest expense
in 1996, compared to 1995 was attributable to a smaller average balance under
the Company's credit lines necessary to finance the Company's capital
expenditures, as well as to the Company's paying only six months of interest on
the Debentures due to their conversion into Common Stock in the third quarter
of 1996.
    

         Net Income

         Net income of $22.3 million and earnings per share of $1.35 for 1997
were 17% and 6% higher, respectively, than net income of $19.0 million and
earnings per share of $1.27 in 1996.  This increase in net income primarily
reflected the effect of a 31% increase in oil and gas sales revenues as a
result of a 36% increase in natural gas production, an 8% increase in crude oil
production and a 4% increase in gas prices received, offset somewhat by an 11%
decrease in oil prices received.  The lower percentage increase in earnings per
share reflects a 10% increase in weighted average shares outstanding in 1997 as
a result of the conversion of the Debentures into 2.34 million shares of Common
Stock in the third quarter of 1996.  The Company's consolidated effective tax
rate was 32.7%, 33.9% and 28.7% in 1997, 1996 and 1995, respectively.

         Net income of $19.0 million and earnings per share of $1.27 for 1996
were 287% and 159% higher, respectively, than net income of $4.9 million and
earnings per share of $0.49 in 1995.  This increase in net income primarily
reflected the effect of a 134% increase in oil and gas sales revenues as a
result of a 98% increase in natural gas production, a 14% increase in crude oil
production and product price improvements.  The lower percentage increase in
earnings per share reflects a 49% increase in weighted average shares
outstanding for 1996 as a result of the sale of 5.75 million shares of Common
Stock in the third quarter of 1995 and the conversion of the Debentures into
2.34 million shares of Common Stock in the third quarter of 1996.

YEAR 2000

   
         A comprehensive assessment of the Year 2000 issue has been conducted
and a compliance plan is currently underway.  The Company is in the process of
receiving verification of Year 2000 compliance from all hardware and software
vendors.  The Company does not expect that the cost to modify its information
technology infrastructure will be material to its financial condition or
results of operation.  The Company also does not anticipate any material
disruption in its operations as a result of any Year 2000 compliance issues.

                            BUSINESS AND PROPERTIES

GENERAL

   
         The Company is engaged in the development, exploration, acquisition
and operation of oil and gas properties, with a primary focus on U.S. onshore
natural gas reserves.  As of December 31, 1997, the Company had interests in
over 1,500 oil and gas wells located in 10 states, of which the Company
operated 650 wells representing 91% of its proved reserve base.  At such date,
the Company had proved reserves of 361.5 Bcfe, of which approximately 87% were
natural gas, 60% were proved developed and 93% were located in Texas.  The
Company's primary focus is development and exploration drilling in its two core
areas:  the AWP Olmos Field located in South Texas and the Texas Austin Chalk
trend.  The AWP Olmos Field is characterized by long-lived reserves, while the
Austin Chalk trend is characterized by short-lived reserves with high initial
production and rapid decline rates.  These fields accounted for approximately
74% and 15%, respectively, of the Company's proved reserves as of December 31,
1997, and approximately 61% and 19%, respectively, of the Company's production
during 1997.

         On August 26, 1998, the Company purchased the Sonat Properties from
Sonat.  As a result of the Sonat Property Acquisition and assuming the
Proposals are approved by all the Partnerships, the Acquisitions provide the
Company with significant proved reserves as well as additional development and
exploratory opportunities in its core areas.  The Company expects to utilize
its operating expertise in these areas to successfully develop and exploit
these properties.  As a result of these Acquisitions, the Company will increase
its interest in oil and gas wells to over 1,650 wells, of which the Company
will operate approximately 765 wells.  The Company expects reserves in the
Austin Chalk trend to increase to approximately 26% of proved reserves as a
result of the Acquisitions.

         The Company maintains a flexible capital spending program in order to
take advantage of the relative economic attractiveness of either drilling or
acquisition opportunities.  Over the last several years, the Company's growth
in reserves and production  has resulted primarily from its increased acreage
position and drilling activities in the AWP Olmos Field and the Austin Chalk
trend.  Capital expenditures for development and exploration drilling,
primarily in the Company's core areas, were $25.8 million, $71.8 million and
$101.0 million in 1995, 1996 and 1997, respectively, while capital expenditures
for acquisitions were $3.5 million, $1.5 million and $8.4 million.  The Company
has budgeted capital expenditures of $241.5 million for 1998, comprised of
$145.8 million for the Acquisitions and $95.7 million for development and
exploration.  Approximately 59% of the $95.7 million  is targeted for the
continued development of the Company's two core areas.  The Company is also
actively pursuing exploratory drilling opportunities in high potential projects
elsewhere in the Gulf Coast region and in New Zealand.

         In 1997, the Company increased its proved reserves by 40% primarily
from additions through drilling, resulting in the replacement of 522% of 1997
production.  The Company's five-year average reserve replacement costs were
$0.76 per Mcfe.  As a result of increased drilling activity, 1997 production
increased 31% over 1996 production.  Due to economies of scale, geographic
concentration and increased production, general and administrative expenses and
production costs have fallen from $0.57 and $0.39 per Mcfe, respectively, in
1992 to $0.14 and $0.35 per Mcfe, respectively, in 1997.  For the six months
ended June 30, 1998, such costs were $0.13 and $0.34 per Mcfe, respectively.

BUSINESS STRATEGY

   
         The Company pursues a balanced growth strategy that includes an active
drilling program, strategic acquisitions and advanced technologies.  The
Company's operating philosophy is to increase its reserve base through both
drilling and acquisitions, shifting the balance between the two in response to
market conditions.
    

         Key elements of the Company's strategy include the following:

   
         Active Drilling Program.   With the expanded inventory of drilling
prospects that the Company will have following the consummation of the
Acquisitions and when economic drilling conditions improve, the Company intends
to pursue an active program of development drilling in its core areas together
with selected step-out and exploratory drilling on its undeveloped acreage.
Exploratory drilling is based on a "controlled risk" approach, focusing on
regions where the exploration objective would allow the Company to utilize its
technological or geological expertise and that are in close proximity to known
production.  In 1997, the Company drilled 128 net development wells, 127 of
which were in the Company's AWP Olmos Field and Austin Chalk trend core areas,
and seven net exploration wells, of which two were in such core areas.  During
this period, the Company had net drilling success rates of 97% for development
wells and 38% for exploratory wells.  The Company expects to drill a total of
77 gross wells in 1998, 55 of which had been drilled as of June 30, 1998 at a
capital cost of approximately $45.7 million to the Company.  The Company
anticipates that drilling activity in the AWP Olmos Field and the Austin Chalk
trend will represent 59% of the total 1998 drilling budget.  The Company looks
to reduce its overall risk exposure with respect to development and exploration
activities by entering into joint development agreements with industry partners
to share capital exposure for any individual well.  As an example of this
strategy, the Company has active joint development projects with, among others,
UPRC and Chevron in the Austin Chalk trend, in which the Company serves as
operator of a majority of the wells.  See "Business and Properties--
Properties" and "Foreign Activities."

         Strategic Acquisitions.  The Company continuously reviews acquisition
opportunities, including opportunities to acquire properties with significant
proved producing reserves and substantial undeveloped acreage for future
drilling activities.  The Company targets properties located in close proximity
to its current reserves, where such reserves can be increased through
development drilling and where operating efficiencies can be achieved.  Using
these criteria, the Company employs a disciplined, market-driven approach to
acquisitions to augment its drilling program.  The Company has conducted an
ongoing acquisition program since its inception.

         Advanced Technologies.  In order to minimize the risks associated with
development and exploration drilling and enhance operating efficiencies, the
Company has devoted considerable resources to developing advanced technological
expertise.  These technologies include 2-D and 3-D seismic analysis, amplitude
versus offset studies (AVO) and detailed formation depletion studies.  The
Company has also attained substantial expertise in horizontal well drilling
technology, having participated as of June 30, 1998 in 70 such wells in the
Austin Chalk trend, 62 of which have been successful.  Additionally, the
Company uses innovative fracturing methods, coiled tubing technology and
computer telemetry to monitor well performance.  As a result of these
technologies, the Company has enhanced its production yields while reducing its
costs per Mcfe.  Application of these technologies has enabled the Company to
achieve historical drilling success rates that exceed applicable U.S. industry
averages.

RECENT DEVELOPMENTS

   
         In accordance with its business strategy described above, the Company
plans to enter into the following transactions:

         Sonat Properties Acquisition. On August 26, 1998 the Company purchased
from Sonat, effective April 1, 1998, certain producing oil and gas properties
located in the Texas and Louisiana Austin Chalk trend for approximately $87.6
million in cash, with a majority of the purchase price being allocated to
proved reserves.  As of April 1, 1998, estimated proved reserves for the Sonat
Properties were 91.1 Bcfe, of which approximately 56% was natural gas, with
1997 production of 22.0 Bcfe, of which approximately 51% was natural gas.  The
properties include 156 producing oil and natural gas wells in the Brookeland
Field in Southeast Texas and the Masters Creek Field in Western Louisiana, 21
saltwater disposal wells, a 20% interest in two natural gas plants, associated
production facilities and working interests in approximately 200,000
undeveloped net acres containing more than 50 drilling locations.  The Company
became operator of 113 of the 156 wells.  Net production averaged 8,997 barrels
per day and 34.5 Mmcf per day (88.5 Mmcfe per day) during February 1998.
Production is expected to rise to 12,000 barrels per day and 49.0 Mmcf per day
(121.0 Mmcfe per day) during the third quarter of 1998 when equipment repairs
involving seven Sonat-operated wells are completed at the Masters Creek gas
processing facility.  The two gas plants have combined capacity of 250 Mmcfe
per day, and in 1997 had operating cash flow of $2.8 million.  UORC is the
operator of both plants.

         The Sonat Properties Acquisition extends one of the Company's core
areas by adding producing reserves that the Company believes will significantly
increase its production on a short-term basis.  Furthermore, as a result of the
Company's extensive experience in other parts of the Austin Chalk trend, the
Company believes that it can successfully exploit incremental drilling
opportunities in the future.

         Partnership Properties Acquisition.  The Company hereby offers to
purchase all of the Partnership Properties owned by each of the 63
Partnerships, subject to approval by the investors in each such Partnership.
As of December 31, 1997, estimated proved reserves of the Partnership
Properties were 93.5 Bcfe, with 1997 production of 12.4 Bcfe.  As of January 1,
1998, the net purchase price for the Partnership Properties (after deducting
the portion of the total purchase price allocated to the Company through its
ownership interests in the Partnerships) is expected to be approximately $70.6
million, subject to certain reductions based on cash flow distributions to the
Partnerships prior to closing.  A portion of the purchase price for the
Partnership Properties may be funded by the issuance of up to 2.5 million
shares of Common Stock to Investors in the Partnerships who elect to receive
Common Stock in lieu of some or all of the cash that they will be entitled to
receive upon their Partnership's liquidation.

         The Company believes that the Partnership Properties Acquisition
represents an opportunity to acquire properties having development and
exploration potential, without incurring additional overhead.  As a result of
the Company's geological and operating experience with most of the Partnership
Properties, with its technological and drilling expertise, the Company expects
to enhance the recovery of the reserves on these properties.

PROPERTIES

         The Company's proved reserves are geographically concentrated, with
approximately 89% of the Company's proved reserves at December 31, 1997,
attributable to its two largest properties, the AWP Olmos Field and the Austin
Chalk trend.

         AWP Olmos Field

   
         The Company's most significant property is located in the AWP Olmos
Field in South Texas.  The Company has extensive expertise in the AWP Olmos
Field and a long history of experience with low-permeability tight-sand
formations typical of this field.  Since acquiring its first AWP Olmos Field
acreage in 1988, the Company has made detailed studies of drainage patterns in
the formation and has introduced innovations in fracture design and
implementation methods and coiled tubing technology, all of which reduce
overall costs and improve recoveries.

         The AWP Olmos Field represented approximately 74% of the Company's
proved reserves at December 31, 1997, and approximately 61% of the Company's
1997 production.  As a result of the Acquisitions, the Company expects the AWP
Olmost Field to decrease to approximately 52% of the Company's proved reserves.
At December 31, 1997, the Company owned interests in and was the operator of
approximately 400 wells producing natural gas from the Olmos Sand Formation at
a depth of approximately 10,000 feet.  The Company has engaged in extensive
fracturing operations to increase the permeability of the formation and flow of
gas from the wells.  In addition, the Company has used coiled tubing velocity
strings in several wells to improve production rates and is able to monitor
fracturing operations from its Houston headquarters through direct computer
access to the field.

         During 1997, the Company purchased, for approximately $3.8 million,
Olmos producing properties strategically located in the heart of its existing
leasehold in the AWP Olmos Field.  The purchase included 35 producing wells, 35
new development drilling locations, and a related 20-mile pipeline.  Net proved
reserves attributable to the purchase are approximately 25.0 Bcfe, with current
production of approximately 2.0 Mmcfe per day.  Since the purchase, the
Company's efforts to improve production have resulted in an increase to 2.5
Mmcfe per day.

         In 1997, the Company drilled 142 gross (137 successful) development
wells (120.4 net) in this field and one unsuccessful exploratory well northwest
of the field.  The Company or entities managed by the Company own 100% of the
working interest in this field.  During 1997, the Company maintained its
leasehold position in this area.  The Company anticipates further acquisition
of acreage in this area in the future, if warranted.  The Company plans to
drill approximately 57 additional development wells and four exploratory wells
to the Olmos formation in 1998.
    

         Austin Chalk Trend

   
         At December 31, 1997, the Company owned drilling and production rights
in 175,022 gross acres and 112,918 net acres in the Austin Chalk trend
containing substantial proved undeveloped reserves.  The Austin Chalk trend
represented approximately 15% of the Company's proved reserves at December 31,
1997.  As a result of the Acquisitions, the Company expects the Austin Chalk
trend to approximately 26% of the Company's proved reserves.  Production from
this field constituted 19% of oil and gas production in 1997.  The wells in
this trend are all horizontal, primarily natural gas, that deliver high initial
flow rates
    







                                      128
<PAGE>   145

and strong initial cash flows which decline rapidly.  The Company believes
these reserves complement its long-lived reserves in the AWP Olmos Field.
Since 1992, the Company has participated in 55 horizontal wells in the trend
with a 91% success rate, including 16 successful development wells out of 17
gross (6.3 net) drilled and two successful exploratory wells out of five
drilled in 1997.  The Company believes its success is attributable to its
ability to identify hydrocarbon-bearing fractures, relying on its expertise in
seismic data analysis, and its ability to drill and operate horizontal wells.
The Company anticipates drilling 30 development wells and three exploratory
wells in the Austin Chalk during 1998.  The acquisition of seismic data in the
Cougar Run and Nimitz areas in Fayette County has helped in upgrading locations
to drill numerous horizontal wells targeting the Austin Chalk formation
determined from previous seismic data acquisitions and subsequent successful
drilling in the Rocky Creek and North Fayetteville prospects.

         Substantial portions of its property interests in the Austin Chalk
trend have been acquired through joint development arrangements with industry
partners who are active participants in exploration of the Austin Chalk trend.
The Company entered into its first such venture in 1993, in an arrangement that
covered approximately 8,800 acres, in which the Company currently has an
average working interest of 25%.  In September 1995, the Company entered into
another joint development agreement providing for an area of mutual interest
covering 19,500 gross acres and pursuant to which the Company and its industry
partner in the venture alternate serving as operator of any wells drilled on
the acreage.  During 1996, the Company purchased its partner's interest in
9,500 of these gross acres, and the joint development arrangement now covers a
10,000 gross acre block in which the Company expects to have an average working
interest of 30% to 35% based on certain assumptions relating to elections with
respect to the drilling of various wells.  The Company has a 100% working
interest in the 9,500 acres.

         In 1996, the Company reached joint development arrangement covering
approximately 8,000 acres in Washington County, Texas, in which the Company
owns a 25% working interest with an industry partner.  This joint development
area has been further expanded to encompass approximately 17,000 gross acres.
Simultaneously, the Company entered into two additional joint development
agreements covering an approximate 6,300 gross acre area, in which the Company
owns a 50% working interest, and an approximate 8,100 gross acre area, in which
the Company owns a 75% working interest and serves as operator.

   
         Also in 1997, the Company acquired a 50% working interest in 20,000
net acres adjoining the North Fayetteville Prospect area, for which it will
serve as operator.  The initial test well was spudded in December 1997.

         The Company signed a joint development agreement with Chevron
encompassing 144,000 gross (64,000 net) acres in central Texas where the
Company and Chevron will participate together in the drilling of a number of
wells targeted for the Edwards Limestone, Sligo, Austin Chalk and other
formations in Fayette, Colorado and Austin counties.  The Company and Chevron
will each own an undivided 50% working interest within the area of mutual
interest (AMI), with the Company serving as the operator.  The initial test
well within the AMI will be the Swift-Coufal #1-H well, which is targeted as a
horizontal Austin Chalk completion.

EXPLORATION AND DEVELOPMENT DRILLING ACTIVITIES

   
         In 1991, the Company began to develop an inventory of development and
exploration drilling prospects.  Drilling locations were selected through
intensive geological and geophysical studies of the Company's undeveloped
acreage and other prospects.  During 1995, the Company added 72 Bcfe of proved
reserves through drilling, and in 1996, reserves added by drilling increased to
118 Bcfe.  In 1997, reserves added by drilling increased to 120 Bcfe, with the
Company's success rate at 47% for exploratory wells (seven out of 15 drilled)
and 95% for development wells (159 out of 167 drilled).  These successful
drilling results have led to acquisition by the Company of additional acreage
during 1997 in the area of its two core properties, the AWP Olmos Field in
South Texas and the Austin Chalk trend in Austin, Colorado, Fayette, Walker and
Washington counties in central and eastern Texas.

         The Company pursues a "controlled risk" approach to exploratory
drilling, focusing on specific U.S. regions where its technical staff has
considerable experience, that are in close proximity to known production and
where the potential for significant reserves exists.  The Company seeks to
minimize its exploration risk by investing in multiple prospects, farming out
interests to industry partners and drilling funds, utilizing advanced
technologies and drilling in different types of geological formations.  The
Company utilizes basin studies to analyze targeted formations based on their
potential size, risk profile and economic parameters.
    

         The Company's development strategy is designed to maximize the value
and productivity of its existing properties through development drilling and
recovery methods, enhancing production results through improved field
production techniques, lowering production costs and applying the Company's
technical expertise and resources to exploit producing properties efficiently.
The Company employs various recovery techniques, including water flooding,
fracturing reservoir rock through the injection of high-pressure fluid,
inserting coiled tubing velocity strings to speed gas flow and acid treatments.
The Company believes that the application of fracturing technology and coiled
tubing has resulted in significant increases in production and decreases in
drilling and operating costs, particularly in the Company's largest single
property, the AWP Olmos Field.

   
         The Company's development and exploration activities are conducted by
its in-house exploration staff, assisted by professionals from other
departments, including reservoir engineers, geologists, geophysicists,
petrophysicists, landmen and drilling and operations engineers.  The Company
believes that one of the keys to its success has been its team approach, which
integrates multiple disciplines to maximize efficient utilization of
information leading to drillable projects.

         The Company has increasingly utilized advanced seismic technology to
enhance the quality of its drilling efforts, including two-dimensional (2-D)
and three-dimensional (3-D) seismic analysis and amplitude versus offset (AVO)
studies.  During 1997, the Company completed its first international seismic
acquisition program in two key areas of its holding in New Zealand.  In New
Zealand's Rimu prospect, the Company acquired a 30 kilometer cross-swath, as
well as 2-D seismic data in the Tawa prospect, complementing existing 2-D and
3-D data.  It also acquired 21 miles of 2-D data in the Wheeler Ranch Olmos
trend in South Texas and 51 miles of data in the Fayette County Austin Chalk
trend.  Two more prospects in the Ark-La-Tex region were shot in the form of
2-D swaths of approximately 16 miles each.
    







                                      130
<PAGE>   147

         In addition to exploration and development activities in the AWP Olmos
Field and the Austin Chalk trend, the Company is currently focusing its
exploration activities in three main geographical areas:  the Gulf Coast Basin,
the Wyoming Powder River Basin and the North Louisiana Salt Basin.

         Gulf Coast Basin

   
         The Company defines this area as including all the Texas counties and
Louisiana parishes along the Gulf Coast and extending into Mississippi and
Alabama, which includes all target formations present except the Austin Chalk
trend and the Olmos sand.  In 1997, one successful development well (out of
three) and four successful exploratory wells (out of six) were drilled in the
Gulf Coast Basin, following two successful development wells and one successful
exploratory wells drilled in 1996.  In 1998, 11 development and exploratory
wells and three exploratory wells are scheduled for drilling in the Gulf Coast
Basin.  The locations were selected utilizing traditional geologic studies
combined with analyses of available seismic data.

         During 1997, the Company acquired 1,920 gross acres in Jim Hogg County
in which the Company owns a minimum 75% working interest.  [Additionally, the
Company has an oil and gas lease option on an additional 8,500 gross acres in
the area until August 1, 1998.]  A well drilled by the Company to the Queen
City formation, the Chaparral #1, in 1997 was highly successful.  Of the [11]
development wells expected to be drilled in the Gulf Coast Basin in 1998, [six]
will be drilled on this acreage. Three of those [six] have already been
successfully drilled in the first half of 1998, [with the fourth well currently
being drilled.]  Further work in the area through licensing additional 2-D data
and acquiring 3-D data jointly with a third party will help complete the
analysis and the interpretation of the acreage for future development in 1998.

         In the Sherburne prospect in south central Louisiana, the Company has
been working with 2-D seismic data to identify the location of a Sparta
formation, which was successfully tested in the second quarter of 1998, and has
designed a 2-D seismic cross-swath acquired in March 1998, to identify deeper
high-yield structures in the Wilcox trend.  A Sparta development well is
planned for the fourth quarter of 1998.
    

         Wyoming Powder River Basin

   
         The Company intends to drill [one] development and [two] exploratory
wells and in 1998.  In 1997, the Company successfully drilled one out of two
exploratory wells in the Minnelusa trend in Campbell County, Wyoming.  In 1996,
the Company successfully drilled one out of three development wells and one out
of three exploratory wells in the trend.  The Minnelusa trend has been the
subject of extensive study by the Company's multi-disciplinary teams in order
to identify the location of stratigraphic hydrocarbon traps.  Recently, the
Company has shifted its emphasis to pursue the Cretaceous trend in southern
Campbell County and northern Converse County in Wyoming, as well as north into
the Williston Basin in Daniels County, Montana.  The Company has licensed
various existing 2-D seismic data to help map the structural and stratigraphic
traps that have been identified for drilling in 1998.
    

         North Louisiana Salt Basin

   
         The North Louisiana Salt Basin covers the neighboring corners of
Arkansas, Louisiana, and Texas (Ark-La-Tex region).  In 1997, the Company
drilled two wells, one development and one exploratory, one
    






                                      131
<PAGE>   148
   
of which (the development well) was successful.  In 1996, the Company drilled
five successful wells, four of which were exploratory.  The Company plans to
drill [two] exploratory wells in the region in 1998.  In this area, the
Smackover formation is a prolific hydrocarbon producer from multiple levels and
from a variety of structures, including fault traps, salt anticlines, basement
structures and stratigraphic traps.  In northern Louisiana and southern
Arkansas in the Smackover trend, in 1997 the Company acquired and completed
processing two sets of 2-D seismic swaths that have been interpreted to yield
numerous exploratory locations.  Additional seismic acquisitions are planned in
Bossier Parish, Louisiana, to delineate a prospect pending the drilling of a
test well to determine the presence of hydrocarbon sands in the area.

OPERATIONS

         The Company generally seeks to be named as operator for wells in which
it or its affiliated limited partnerships and joint ventures have acquired a
significant interest, although this typically occurs only when it or its
affiliates own the major portion of the working interest in a particular well
or field.  The Company acts as operator of approximately 650 wells at December
31, 1997, which comprise approximately 91% of the Company's total proved
reserves.

         As operator, the Company is able to exercise substantial influence
over development and enhancement of a well and to supervise operation and
maintenance activities on a day-to-day basis.  The Company does not conduct the
actual drilling of wells on properties for which it acts as operator.  Drilling
operations are conducted by independent contractors engaged and supervised by
the Company.  The Company employs petroleum engineers, geologists and other
operations and production specialists who strive to improve production rates,
increase reserves and lower the cost of operating its oil and gas properties.

         Oil and gas properties are customarily operated under the terms of a
joint operating agreement, which provides for reimbursement of the operator's
direct expenses and monthly per-well supervision fees.  Per-well supervision
fees vary widely depending on the geographic location and producing formation
of the well, whether the well produces oil or gas, and other factors.  Such
fees received by the Company in 1997 ranged from $200 to $1,481 per well per
month.

MARKETING OF PRODUCTION

         The Company typically sells its gas production at or near the
wellhead, although in some cases gas must be gathered by the Company or other
operators and delivered to a central point.  Gas production is generally sold
in the spot market at prevailing prices.  The Company generally sells its oil
production at prevailing market prices.  The Company does not refine any oil it
produces.  During the year ended December 31, 1997, three oil or gas purchasers
each accounted for 10% or more of the Company's revenues, with those purchasers
together accounting for 42%.  Three oil or gas purchasers accounted for 10% or
more of the Company's revenues during the year ended December 31, 1996, with
those purchasers







                                      133
<PAGE>   150

accounting for approximately 51%.  Because of the availability of other
purchasers, the Company does not believe that the loss of any single oil or gas
purchaser or contract would materially affect its sales.

   
         The Company has entered into gas processing and gas transportation
agreements with respect to its natural gas production in the AWP Olmos Field
with Valero Transmission, L.P. and its affiliates ("Valero") for up to 75.0
Mmcf per day.  These contracts have initial six-year terms, with automatic
one-year extensions unless earlier terminated.  The Company believes that these
arrangements adequately provide for its gas transportation and processing needs
in the AWP Olmos Field for the foreseeable future.  Additionally, at the
discretion of the Company and Valero, the gas processed and transported under
these agreements may be sold to Valero at monthly indexed prices based upon the
current natural gas price.  Effective July 31, 1997, Valero was merged with
Pacific Gas & Electric Corporation ("PG&E").   This merger did not affect the
contractual obligations between the Company and Valero.
    

         Much of the Company's Austin Chalk production from Fayette and
Washington counties, Texas, is currently dedicated under long-term gas purchase
and gas processing contracts with Aquila Southwest Pipeline Corporation
("Aquila").  The Company believes that these contracts adequately provide for
the gas purchase and processing needs of its Austin Chalk production, subject
to practical limitations inherent in gas field operations.  The prices received
are redetermined monthly to reflect the current natural gas price.

         The following table summarizes sales volumes, sales prices and
production cost information for the Company's net oil and gas production for
the three-year period ended December 31, 1997.  "Net" production is production
that is owned by the Company either directly or indirectly through partnerships
or joint venture interests and produced to its interest after deducting
royalty, limited partner and other similar interests.

(1)   Natural gas production for 1997, 1996 and 1995 includes 1,015,226,
1,156,361 and 1,211,255 Mcf, respectively, delivered under the volumetric
production payment agreement pursuant to which the Company is obligated to
deliver certain monthly quantities of natural gas (see Note 1 to the Company's
Consolidated Financial Statements).  Under the volumetric production payment
entered into in 1992, as of December 31, 1997, the Company has a remaining
commitment to deliver approximately 2.0 Bcf of gas meeting certain heating
equivalent and quality standards through the later of October 2000 or such time
as the Company has delivered the requisite amount of gas under the agreement
when such agreement expires.  Since entering into this agreement, these
properties have produced in excess of the required monthly delivery
requirements.

PRICE RISK MANAGEMENT

   
         The Company's revenues are primarily the result of sales of its oil
and natural gas production.  Market prices of oil and natural gas may fluctuate
and adversely affect operating results.  To reduce some of this risk, the
Company does engage periodically in certain limited hedging activities, but
only to the extent of buying protection price floors for portions of its and
the limited partnerships' oil and gas production.   Costs and benefits
associated with these price floors are recorded accordingly as a reduction or
increase, respectively, in oil and gas sales revenue and were not significant
for any year presented.  The cost to purchase a put options is amortized over
the option period.

         For the first [seven] months of 1998, the Company had entered into
hedging contracts covering 11,000,000 MMBtu and 120,000 barrels of the
Company's and its affiliated Partnerships' production, representing 48% and 13%
of oil and gas production, respectively, at a total cost of approximately $0.4
million with benefits of approximately $0.1 million being received, resulting
in a net cash outlay of approximately  $0.3 million.
    

ACQUISITION ACTIVITIES

   
         Since 1979, the Company has acquired approximately $478.0 million of
producing oil and natural gas properties on behalf of itself and its
co-investors in 129 separate transactions.  In recent years, the Company's
acquisition activities have declined, as it has fulfilled its obligation to buy
producing properties for the remaining partnerships that invested in such
properties.  As of December 31, 1997, all such partnerships investing in
producing properties had spent their available capital resources on producing
properties.  Therefore, the Company anticipates all future acquisition activity
will be for its own behalf.  Cumulatively, the Company has acquired for its own
account approximately $121.5 million of producing properties, with original
proved reserves estimated at 182.2 Bcfe.  The Company's acquisition
expenditures in the past three years were approximately $8.4 million, $1.5
million and $3.5 million for properties acquired in 1997, 1996 and 1995,
respectively.  The Company's acquisition costs have averaged $0.31 per Mcfe
over this three-year period.

         The Company uses a disciplined, market-driven approach to
acquisitions, generally seeking to acquire properties located in close
proximity to its current reserves with the potential to add reserves and
production through additional development and exploration efforts.

FOREIGN ACTIVITIES

         New Zealand

   
         During 1996, the Company was issued two Petroleum Exploration Permits
by the New Zealand Minister of Energy.  The first permit covered approximately
65,000 acres in the Onshore Taranaki Basin of New Zealand's North Island, and
the second covered approximately 69,300 adjacent acres.  The Company formed a
wholly owned subsidiary, Swift Energy New Zealand Limited, for the purpose of
conducting its New Zealand activities and assigned its interest in the permits
to that subsidiary during the third quarter of 1997.  In March 1998, the
Company surrendered approximately 46,400 acres covered in the first permit and
the remaining acreage has been included as an extension of the area covered in
the second permit.  Under the terms of the expanded permit, the Company is
obligated to drill one exploratory well prior to August 12, 1999.  All other
obligations under the permit have been fulfilled including the reinterpretation
of existing seismic data and the acquisition and processing of new seismic
data.  On April 1, 1998, the Company reached an agreement in principle with
Bligh Oil & Minerals N.L. ("Bligh"), an Australian company, to obtain from
Bligh a 25% working interest in two additional New Zealand Petroleum
Exploration Permits, which cover approximately 51,900 acres, in exchange for a
5% working interest in the Company's permit.  At December 31, 1997, the
Company's investment in New Zealand was approximately $2.5 million, which is
included in the unproved properties portion of oil and gas properties.
    

         Russia
   
         On September 3, 1993, the Company signed a Participation Agreement
with Senega, a Russian Federation joint stock company (in which the Company has
an indirect interest of less than 1%), to assist in the development and
production of reserves from two fields in Western Siberia.  The agreement
provides  the Company with a minimum of 5% net profits interest from the sale
of hydrocarbon products from the fields in exchange for the Company's
managerial, technical and financial support to Senega.  Additionally, the
Company purchased a 1% net profits interest from Senega for $0.3 million.
    

         On December 10, 1997, the Company amended and restated a Participation
Agreement with Senega that it originally entered into in 1995.  Under the
amended and restated Participation Agreement, the Company retains its 6% net
profits interest in the Samburg Field and has agreed to assist Senega in
obtaining investments necessary to develop the field.  Senega is charged with
the management and control of the field development.  At December 31, 1997, the
Company's investment in Russia was approximately $10.2 million and is included
in the unproved properties portion of oil and gas properties.

         Venezuela

         The Company formed a wholly owned subsidiary, Swift Energy de
Venezuela, C.A., for the purpose of submitting a bid on August 5, 1993, under
the Venezuelan Marginal Oil Field Reactivation Program.  Although the Company
did not win the bid, it has continued to pursue cooperative ventures involving
other fields and opportunities in Venezuela.  The Company evaluated a number of
blocks being offered by Petroleos de Venezuela, S.A. under the Third Operating
Agreement Round in 1997, but decided against submitting any bid on these
blocks.  The Company has entered into an agreement with Tecnoconsult, S.A., a
Venezuelan company, to jointly formulate and submit a proposal to Petroleos de
Venezuela, S.A. for the construction and operation of a methane pipeline.
Currently, the technical and economic feasibility of the project is under
study.  At December 31, 1997, the Company's investment in Venezuela was
approximately $2.4 million and is included in the unproved properties portion
of oil and gas properties, net of impairments of $45,668.

OIL AND GAS RESERVES

   
         The following table presents information regarding proved reserves of
oil and gas attributable to the Company's interests in producing properties as
of December 31, 1997, 1996 and 1995.  The information set forth in the table is
based on proved reserves reports prepared by the Company and audited by H.J.
Gruy, independent petroleum engineers.  H.J. Gruy's estimates were based upon
review of production histories and other geological, economic, ownership and
engineering data provided by the Company.  In accordance with Commission
guidelines, the Company's estimates of future net revenues from the Company's
proved reserves and the PV-10 Value are made using oil and gas sales prices in
effect as of the dates of such estimates and are held constant throughout the
life of the properties, except where such guidelines permit alternate
treatment, including, in the case of gas contracts, the use of fixed and
determinable contractual price escalations.  Proved reserves as of December 31,
1997, were estimated based upon weighted average prices of $2.78 per Mcf and
$15.76 per barrel, compared to $4.47 and $2.41 per Mcf and $23.75 and $18.07
per barrel as of December 31, 1996 and 1995, respectively.  As of June 30,
1998, such prices were $2.59 per Mcf and $12.32 per barrel.  The Company has
interests in certain tracts that are estimated to have additional hydrocarbon
reserves that cannot be classified as proved and are not reflected in the
following table.  The proved reserves presented for all periods also exclude
any reserves attributable to the volumetric production payment.

</TABLE>

         The table also sets forth estimates of future net revenues presented
on the basis of unescalated prices and costs in accordance with criteria
prescribed by the Commission and their PV-10 Value.  Operating costs,
development costs and certain production-related taxes were deducted in
arriving at the estimated future net revenues.  No provision was made for
income taxes.  The estimates of future net revenues and their present value
differ in this respect from the standardized measure of discounted future net
cash flows set forth in Supplemental Information to the Consolidated Financial
Statements of the Company, which is calculated after provision for future
income taxes.  In cases where producing properties are subject to gas purchase
contracts and the amount of gas purchased thereunder was reduced during 1997,
gas projections used to estimate future net revenues were based on the reduced
gas purchases for the affected producing properties.  The assumption was made
that purchases in 1998 and thereafter will be made at an unrestricted level.

   
         The Company's total proved developed and undeveloped reserves have
increased substantially (40%) at December 31, 1997, when compared to December
31, 1996, as shown above and in Supplemental Information to the Company's
Consolidated Financial Statements.  A substantial portion (40%) of the reserves
are proved undeveloped reserves, which reflects the increased emphasis on
development and
    


                                      138
<PAGE>   155
   
exploration activities, and is consistent with the proportions in 1996 of 39%
proved undeveloped and 61% proved developed.

         Changes in quantity estimates and the estimated present value of
proved reserves are affected by the change in crude oil and natural gas prices
at the end of each year.  While the Company's total proved reserves  quantities
(on an equivalent Bcfe basis) at year-end 1997 increased by 40% over reserves
quantities a year earlier, the PV-10 Value of those reserves decreased 26% from
the PV-10 Value at year-end 1996.  This decrease was primarily due to high
product prices at year-end 1997, with the price of gas declining 38% during
1997 from $4.47 at December 31, 1996, to $2.78 at year-end 1997, matched by a
34% decrease in the price of oil between the two dates, from $23.75 to $15.76.
Estimations of the PV-10 Value and other reserve data are subject to a number
of factors.  [See "Risk Factors - Uncertainty of Estimates of Reserves and
Future Net Revenues."]

         A portion of the Company's proved reserves has been accumulated
through the Company's interests in the limited partnerships for which it serves
as general partner.  The estimates of future net cash flows and their present
values, based on period end prices, assume that some of the limited
partnerships in which the Company owns interests will achieve payout status in
the future.  Four of the limited partnerships had achieved payout status at
June 30, 1998.

         No other reports on the Company's reserves have been filed with any
federal agency.  Estimates of the PV-10 Value and other reserve data are
subject to a number of factors.  [See "Risk Factors - Uncertainty of Estimates
of Reserves and Future Net Revenues."]

OIL AND GAS ACREAGE

   
         As is customary in the industry, the Company generally acquires oil
and gas acreage without any warranty of title except as to claims made by,
through or under the transferor.  See "Risk Factors--Risks Associated with
Acquisitions" for a discussion of the risks associated with such a policy.  The
following table sets forth the developed and undeveloped domestic leasehold
acreage held by the  Company at December 31, 1997:

PARTNERSHIPS

   
         For many years, the Company relied on limited partnerships as its
principal financing vehicle to fund its activities.  The Company has formed and
served as managing general partner of 108 limited partnerships which have
raised a total of approximately $505.6 million at June 30, 1998.  However, in
recent years as the Company has increasingly shifted its emphasis to
development and exploration activities and its reserves base has grown, the
Company has significantly reduced its reliance on limited partnership
financing.  The Company is hereby submitting the Proposals to the Investors in
63 Partnerships to sell substantially all of their oil and gas assets to the
Company and thereafter liquidate the Partnerships.  If all such proposals are
approved, only four public production partnerships and 12 private drilling
partnerships will remain.

         The Company intends to continue offering private drilling partnerships
in the future.  The existing private drilling partnerships have been offered on
a no-load basis under which the Company pays all selling and offering expenses
of the partnership offering.  Amounts paid by the Company are treated as a
capital contribution to each partnership.  The Company also is entitled to a
general and administrative overhead allowance and an incentive amount.  In
certain partnerships, the Company does not bear any of the costs incurred in
acquiring or drilling properties.  The Company pays approximately 20% of all
continuing costs (approximately 30% after payout and 35% after 200% payout),
and the Company is entitled to receive 20% of net revenues distributed by each
such partnership prior to payout, 30% distributed after payout, and 35%
distributed after 200% payout.  As managing general partner of certain other
partnerships, the Company pays out of its own corporate funds the capital costs
(consisting of all prospect costs and the non-deductible, tangible portion of
drilling and completion costs).  The Company pays approximately 40% of all
continuing costs (approximately 45% after payout and 50% after 200% payout),
and the Company is entitled to receive 40% of net revenues distributed by each
such partnership prior to payout, 45% distributed after payout and 50%
distributed after 200% payout.
    

         Under the terms of the Company's limited partnership programs, the
Company generally retains the right to engage in oil and gas exploration and
production for its own account.  The partnership agreement for each limited
partnership contains detailed provisions regarding the terms upon which a
variety of transactions between the Company and the limited partnerships may be
carried out.  These restrictions, which may limit the ability of the Company to
take certain actions, are intended to ensure that transactions between the
Company and the limited partnerships are fair to such limited partnerships.

   
    

REGULATIONS

         Environmental Regulations
   
         The Company's operations are subject to numerous laws and regulations
governing the use, management and disposal of hazardous and non-hazardous
substances and wastes, and otherwise relating to environmental protection and
employee health and safety.  These laws and regulations may require the
acquisition of a permit before drilling commences, restrict the types,
quantities and concentration of various substances that can be released into
the environment in connection with drilling and production activities, limit or
prohibit drilling activities on certain lands lying within wilderness areas,
wildlife refuges or preserves, wetlands and other protected areas, and impose
substantial liabilities for pollution resulting from the Company's operations.
Changes in environmental laws and regulations occur frequently, and any changes
that result in more stringent and costly waste handling, disposal and cleanup
requirements could
    







                                      141
<PAGE>   158
   
have a significant impact on the operating costs of the Company, as well as the
oil and gas industry in general.  Although Management believes that the Company
is in substantial compliance with current applicable environmental laws and
regulations, there can be no assurance the costs of maintaining compliance with
existing and future requirements will not have a material adverse impact on the
Company's business, results of operations and financial condition.

         The Company frequently buys interests in underdeveloped crude oil and
natural gas properties that have been operated by others in the past, and
therefore may become liable for damage or pollution caused by the former
operators of such properties.  Future site restoration, net of salvage values,
is estimated on a property-by-property basis and amortized to expense as the
Company's capitalized oil and gas property costs are amortized.  The Company
computes the provision for such amortization on the unit-of-production method.
The Company's operations also are subject to all of the risks normally incident
to the operation and development of crude oil and natural gas properties,
including encountering unexpected formations or pressures, blowouts, cratering
and fires, any of which could result in personal injuries, loss of life,
pollution damage and other damage to the properties of the Company and others.
The Company maintains insurance against certain losses or liabilities arising
from its operations in accordance with customary industry practices and in
amounts that Management believes to be reasonable.  For certain operational
risks, however, insurance is either unavailable or prohibitively expensive.  A
significant liability for which the Company is uninsured or not fully insured
could have a material adverse effect on the Company's business, results of
operations and financial condition.

         The Oil Pollution Act of 1990 ("OPA") imposes a variety of
requirements on "responsible parties" related to the prevention of crude oil
spills and liability for damages resulting from such spills into U.S. waters.
"Responsible parties" include, among others, the owners and operators of
onshore facilities, vessels and pipelines, and such parties may be held
strictly, jointly and severally liable for removal costs and certain other
damages caused by covered oil spills.  Failure to comply with OPA's operating
requirements or to cooperate with removal activities after a spill event may
result in civil or criminal enforcement.  The Company is not subject to any
enforcement proceedings under OPA.

         The Federal Water Pollution Control Act of 1972, as amended (the
"FWPCA"), imposes restrictions and strict controls regarding the discharge of
produced waters and other oil and gas wastes into navigable waters.  The
Company is required to obtain and maintain compliance with permits authorizing
it to discharge pollutants into state and federal waters.  Certain state
discharge regulations and the Federal national Pollutant Discharge Elimination
System permits prohibit the discharge of produced water and sand, drilling
fluids, drill cutting and certain other substances related to the oil and gas
industry into coastal waters.  The FWPCA provides for civil, criminal and
administrative penalties for any unauthorized discharges of oil and other
hazardous substances in reportable quantities and, along with OPA, imposes
substantial potential liability for the costs of removal, remediation and
damages.  State laws for the control of water pollution also provide varying
civil, criminal and administrative penalties and impose liability for
discharges of petroleum or its derivatives, or other pollutants, into state
waters.

         The Comprehensive Environmental Response, Compensation, and Liability
Act ("CERCLA"), and certain analogous state laws, impose strict, joint and
several liability on certain classes of persons concerning the release or
threatened release of hazardous substances into the environment.  These persons
may include the current or past owner or operator of property on which a
release occurred, as well as persons that disposed or arranged for the disposal
of the hazardous substances found at the site.  Responsible parties under
CERCLA may be strictly, jointly and severally liable to both the government
    







                                      142
<PAGE>   159

   
and private third parties for investigation and cleanup costs, including
natural resources damages.  In addition, neighboring landowners and other third
parties frequently file claims for personal injury and property damage relating
to such matters.  Currently, the Company is not aware of any pending or
threatened claims, actions or investigations under CERCLA or similar state
laws.

         The Resource Conversation and Recovery Act ("RCRA") is the principal
federal statute governing the treatment, storage and disposal of hazardous
wastes.  RCRA imposes stringent operating requirements (and liability for
failure to meet such requirements) on persons who generate or transport
hazardous waste, and so those who own or operate hazardous waste treatment,
storage or disposal facilities.  At present, RCRA includes a statutory
exemption that allows most crude oil and natural gas exploration and production
wastes to be classified as non-hazardous waste.  A similar exemption is
contained in many of the state counterparts to RCRA.  At various times in the
past, proposals have been made to amend RCRA and various state statutes to
rescind the exemption that excludes crude oil and natural gas exploration and
production wastes from regulation as hazardous waste under such statutes.
Repeal or modification of this exemption by administrative, legislative or
judicial process, or through changes in applicable state statutes, would
increase the volume of hazardous waste that the Company would be required to
manage and dispose.  Hazardous wastes are subject to more rigorous and costly
disposal requirements than are non-hazardous wastes.  Any such change  in the
applicable statutes may require the Company to make additional capital
expenditures or incur increased operating expenses.
    

         Federal Regulation of Natural Gas

         The transportation and sale of natural gas in interstate commerce is
heavily regulated by agencies of the federal government.  The following
discussion is intended only as a brief summary of the principal statutes,
regulations and agency orders that may affect the production and sale of the
Company's natural gas.  This summary should not be relied upon as a complete
review of applicable natural gas regulatory provisions.

         FERC Orders.  Several major regulatory changes were implemented by the
Federal Energy Regulatory Commission ("FERC") after 1985 that affect the
economics of natural gas production, transportation and sales.  In addition,
the FERC continues to promulgate revisions to various aspects of the rules and
regulations affecting those segments of the natural gas industry that remain
subject to the FERC's jurisdiction.  In April 1992, the FERC issued Order No.
636 pertaining to pipeline restructuring.  This rule requires interstate
pipelines to unbundle transportation and sales services by separately stating
the price of each service and by providing customers only the particular
service desired, without regard to the source for purchase of the gas.  The
rule also requires pipelines to (i) provide nondiscriminatory "no-notice"
service allowing firm commitment shippers to receive delivery of gas on demand
up to certain limits without penalties, (ii) establish a basis for release and
reallocation of firm upstream pipeline capacity and (iii) provide non-
discriminatory access to capacity by firm transportation shippers on a
downstream pipeline.  The rule requires interstate pipelines to use a straight
fixed variable rate design.

         FERC Order No. 500 affects the transportation and marketability of
natural gas.  Traditionally, natural gas has been sold by producers to pipeline
companies, which then resold the gas to end-users.  FERC Order No. 500 alters
this market structure by requiring interstate pipelines that transport gas for
others to provide transportation service to producers, distributors and all
other shippers of natural gas on a nondiscriminatory, "first-come,
first-served" basis ("open access transportation"), so that producers and







                                      143
<PAGE>   160

other shippers can sell natural gas directly to end-users.  FERC Order No. 500
contains additional provisions intended to promote greater competition in
natural gas markets.

   
         It is not anticipated that the marketability of and price obtainable
for the Company's natural gas production will be significantly affected by FERC
Order No. 500.  Gas produced normally will be sold to intermediaries who have
entered into transportation arrangements with pipeline companies.  These
intermediaries will accumulate gas purchased from a number of producers and
sell the gas to end-users through open access transportation.
    

         State Regulations

         Production of any oil and gas by the Company will be affected to some
degree by state regulations.  Many states in which the Company operates have
statutory provisions regulating the production and sale of oil and gas,
including provisions regarding deliverability.  Such statutes, and the
regulations promulgated in connection therewith, are generally intended to
prevent waste of oil and gas and to protect correlative rights to produce oil
and gas between owners of a common reservoir.  Certain state and regulatory
authorities also regulate the amount of oil and gas produced by assigning
allowable rates of production to each well or proration unit.

         Federal Leases

   
         Some of the Company's properties are located on federal oil and gas
leases administered by various federal agencies, including the Bureau of Land
Management.  Various regulations and orders affect the terms  of leases,
development and exploration plans, methods of operation and related matters.
    

EMPLOYEES

         At December 31, 1997, the Company employed 194 persons.  None of the
Company's employees are represented by a union.  Relations with employees are
considered to be good.

FACILITIES

   
         The Company and Swift Energy Marketing Company occupy approximately
75,000 square feet of office space at 16825 Northchase Drive, Houston, Texas,
under a ten year lease expiring in 2005.  The lease requires payments of
approximately $85,000 per month.  A subsidiary of the Company maintains an
office in Denver, Colorado.  The Company has field offices in various locations
from which Company employees supervise local oil and gas operations.
    

LEGAL PROCEEDINGS

         No material legal proceedings are pending other than ordinary routine
litigation incidental to the Company's business.

         beneficial owner, with sole power to dispose and direct the
         disposition of 1,772,300 shares.  Fidelity Management & Research
         Company ("Fidelity"), a wholly- owned subsidiary of FMR Corp., an
         Investment Adviser registered under Section 203 of the Investment
         Advisers Act of 1940, is deemed to be the beneficial owner of
         1,770,100 shares of the Company's stock as a result of acting as an
         investment adviser to several investment companies registered under
         Section 8 of the Investment Company Act of 1940 (the "Funds").
         Members of the Edward C. Johnson 3d family and trusts for their
         benefit are the predominant owners of Class B shares of Common Stock

         into a shareholders' voting agreement under which all Class B shares
         will be voted in accordance with the majority vote of Class B shares.
         Accordingly, through their ownership of voting common stock and the

         Johnson family may be deemed, under the Investment Company Act of
         1940, to form a controlling group with respect to FMR Corp.  Neither

         power to vote or direct the voting of the shares owned directly by the
         Funds, which power resides with the Funds' Boards of Trustees.
    

(6)      Based on Schedule 13G dated January 30, 1998, reflecting shares held
         at December 31, 1997, filed with the Commission, Franklin Advisers
         Inc. ("Advisers"), a wholly-owned subsidiary of Franklin Resources,
         Inc. ("FRI") and an Investment Adviser registered under Section 203 of
         the Investment Advisers Act of 1940, is deemed to be the beneficial
         owner of 1,797,444 shares of the Company's Common Stock as a result of
         acting as an investment adviser to one or more open or closed-end
         investment companies or other managed accounts.  All of these shares
         of the Company's Common Stock are shares that would result upon
         conversion of 57,000,000 units of the Company's Convertible Notes.
         Charles B. Johnson and Rupert H. Johnson, Jr. each own in excess of
         10% of the outstanding common stock of FRI and are the principal
         shareholders of FRI.  Accordingly, Messrs. Charles B. and Rupert H.
         Johnson and FRI may each be deemed to be the beneficial owner of the
         shares of the Company's Common Stock managed by Advisers.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         In the ordinary course of its business, the Company acquires interests
in exploratory and developmental oil and gas prospects and sells interests in
such prospects to unaffiliated third parties.  For the past several years, the
Company has made available for sale to its executive officers and certain other
employees a portion of the interests in certain prospects that would otherwise
have been sold to third parties.  Interests in a prospect are sold to the
Company's employees on terms identical to those at which interests are sold to
third party investors in that prospect.  As a result of enhanced drilling
activity, the amounts invested  by executive officers in such prospects in 1997
increased significantly over previous years.  During 1997, 1996 and 1995,
leasehold and drilling costs associated with such investments in excess of
$60,000 were incurred as follows, respectively:  A. Earl Swift - $322,261,
$135,957 and $69,358; Virgil N. Swift - $390,784, $259,379 and $312,122; Terry
E. Swift - $207,426, $106,621 and $66,618; John R.  Alden - $246,270, $95,080
and $79,927; and only during 1997 for: James M. Kitterman - $133,068, and Bruce
H. Vincent - $220,458.  In connection with these investments in oil and gas
drilling prospects, certain executive officers deferred paying cash for their
investments in such properties, instead assigning the proceeds of production
which over time repay amounts owed, resulting in indebtedness from







                                      149
<PAGE>   166

time to time, of such officers to the Company.  Prior to 1997, the amount of
such indebtedness for any one officer never exceeded $60,000.  In late 1997,
due to increased levels of drilling activity, the balances owed to the Company
grew, with the greatest amounts of indebtedness that exceeded $60,000 during
1998 occurring at July 24, 1998 as follows: Virgil N. Swift - $174,200; John R.
Alden - $130,000; Bruce H. Vincent - $124,000;  and  James M. Kitterman -
$61,900.  Individual executive officers do not pay any interest to the Company
on any such loan balances.

         The Company is the operator of a substantial number of properties
owned by its affiliated limited partnerships and joint ventures and accordingly
charges these entities and third party joint interest owners operating fees.
The Company is also reimbursed for direct, administrative and overhead costs
incurred in conducting the business of the limited partnerships, which totaled
approximately $6,300,000, $6,100,000 and $4,800,000 in 1997, 1996 and 1995,
respectively.  The Company was also reimbursed by the limited partnerships and
joint ventures for costs incurred in the screening, evaluation and acquisition
of producing oil and gas properties on their behalf.  Such costs totaled
approximately $490,000, $250,000 and $600,000 in 1997, 1996 and 1995,
respectively.  In the case where the limited partners voted to sell their
remaining properties and liquidate the limited partnerships, the Company was
also reimbursed for direct, administrative and overhead costs incurred in the
disposition of such properties, which costs totaled approximately $675,000,
$805,000 and $80,000 in 1997, 1996 and 1995, respectively.

               DESCRIPTION OF SWIFT ENERGY COMPANY CAPITAL STOCK

         The following summary description of the capital stock of the Company
does not purport to be complete and is qualified in its entirety by reference
to the Company's Articles of Incorporation, the bylaws of the Company and to
the Certificate of Designation for Series A Junior Participating Preferred
Stock, $.01 par value, copies of which are incorporated by reference as
exhibits to the Registration Statement of which this Prospectus is a part.

PREFERRED STOCK

         The Company is authorized to issue 5,000,000 shares of preferred
stock, par value $.01, of which no shares have been issued.  Under the
Company's Articles of Incorporation, the Company's Board of Directors is
authorized, without shareholder action, to issue preferred stock in one or more
series and to fix the number of shares and the rights, preferences and
limitation of each series.  Among the specific matters that may be determined
by the Board of Directors are the dividend rate, the redemption price, if any,
conversion rights, if any, the amount payable in the event of any voluntary
liquidation or dissolution of the Company and voting rights, if any.

         Preferred Stock Purchase Rights

         On August 1, 1997, the Board of Directors of the Company declared a
dividend of one preferred share purchase right (a "Right") for each outstanding
share of Common Stock payable to the stockholders of record on August 12, 1997.
Each Right entitles the holder to purchase from the Company one one-thousandth
of a share of Series A Junior Participating Preferred Stock, par value $.01 per
share, of the Company (the "Preferred Stock") at a price of $150 per one
one-thousandth of a share of Preferred Stock (the "Purchase Price"), subject to
adjustment.  The description and terms of the Rights are set forth in a Rights
Agreement dated as of August 1, 1997, as the same may be amended from time to
time (the "Rights Amendment"), between the Company and American Stock Transfer
& Trust Company, as Rights Agent (the "Rights Agent").

         Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (with
certain exceptions, an "Acquiring Person") has acquired beneficial ownership of
15% or more of the outstanding shares of Common Stock or (ii) 10 business days
(or such later date as may be determined by action of the Board of Directors
prior to such time as any person or group of affiliated person becomes an
Acquiring Person) following the commencement of, or announcement of an
intention to make, a tender offer or exchange offer the consummation of which
would result in the beneficial ownership by a person or group of 15% or more of
the outstanding shares of Common Stock (the earlier of such dates being called
the "Distribution Date"), the Rights are evidenced by such Common Stock
certificate outstanding on August 12, 1997, together with a copy of the summary
of rights.

         The Rights Agreement provides that, until the Distribution Date (or
earlier expiration of the Rights), the Rights will be transferred with and only
with the Common Stock.  Until the Distribution Date (or earlier expiration of
the Rights), new Common Stock certificates issued after August 12, 1997, upon
transfer of new issuances of Common Stock will contain a notation incorporating
the Rights Agreement by reference.  Until the Distribution Date (or earlier
expiration of the Rights), the surrender for transfer of any certificates for
shares of Common Stock outstanding as of August 12, 1997, even without such





                                      151
<PAGE>   168
notation or a copy of this Summary of Rights, will also constitute the transfer
of the Rights associated with the shares of Common Stock represented by such
certificates.  Following the Distribution Date, separate certificates
evidencing the Rights ("Right Certificates") will be mailed to holders of
record of the Common Stock as of the close of business on the Distribution Date
and such separate Right Certificates alone will evidence the Rights.

         The Rights are not exercisable until the Distribution Date.  The
Rights will expire on July 31, 2007 (the "Final Expiration Date"), unless the
Final Expiration Date is advanced or extended or unless the Rights are earlier
redeemed or exchanged by the Company, in each case as described below.

         In the event that any person or group of affiliated or associated
persons becomes an Acquiring Person, each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereupon become void),
will thereafter have the right to receive upon exercise of a Right that number
of shares of Common Stock or other securities or assets having a market value
of two times the exercise price of the Right.

         In the event that, after a person or group has become an Acquiring
Person, the Company is acquired in a merger or other business combination
transaction or 50% or more of its consolidated assets or earning power are
sold, proper provisions will be made so that each holder of a Right (other than
Rights beneficially owned by an Acquiring Person which will have become void )
will thereafter have the right to receive upon the exercise of a Right that
number of shares of Common Stock of the person with whom the Company has
engaged in the foregoing transaction (or its parent) that at the time of such
transaction have a market value of two times the exercise price of the Right.

         At any time after any person or group becomes an Acquiring Person and
prior to the earlier of one of the events described in the previous paragraph
or the acquisition by such Acquiring Person of 50% or more of the outstanding
shares of Common Stock, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such Acquiring Person which will have become
void), in whole or in part, for shares of Common Stock or Preferred Stock (or a
series of the Company's preferred stock having equivalent rights, preferences
and privileges), at an exchange ratio of one share of Common Stock, or a
fractional share of Preferred Stock (or other preferred stock) equivalent in
value thereto, per Right.

         Shares of Preferred Stock purchasable upon exercise of the Rights will
not be redeemable.  Each share of Preferred Stock will be entitled, when, as
and if declared, to a dividend payment per share equal to an aggregate dividend
of 1000 times the dividend declared per share of Common Stock.  In the event of
liquidation, dissolution or winding up of the Company, the holders of the
Preferred Stock will be entitled to a minimum preferential payment of $1.00 per
share (plus any accrued but unpaid dividends) but will be entitled to an
aggregate payment of 1000 times the payment made per share of Common Stock.
Each share of Preferred Stock will have 1000 votes, voting together with the
Common Stock.  Finally, in the event of any merger, consolidation or other
transaction in which outstanding shares of Common Stock are converted or
exchanged, each share of Preferred Stock will be entitled to receive 1000 times
the amount received per share of Common Stock.  These Rights are protected by
customary antidilution provisions.

         Because of the nature of the Preferred Stock's dividend, liquidation
and voting rights, the value of the one one-thousandth of a share of Preferred
Stock purchasable upon exercise of each Right should approximate the value of
one share of Common Stock.

<PAGE>   169

         The offer and sale of the Preferred Shares or Common Shares issuable
upon exercise of the Rights will be registered pursuant to the Securities Act
of 1933, as amended; such registration will not become effective until the
Rights become exercisable.

         The number of one one-thousandths of a Preferred Share or other
securities or property issuable upon exercise of the Rights, and the Purchase
Price payable, are subject to customary adjustments from time to time to
prevent dilution.

         At any time prior to the earlier of (i) the Distribution Date or (ii)
the Final Expiration Date, the Board of Directors of the Company may redeem all
but not less than all of the then outstanding Rights at a price of $0.01 per
Right (the "Redemption Price").  The redemption of the Rights may be made
effective at such time, on such basis and with such conditions as the Board of
Directors in its sole discretion may establish.  At the effective time of such
redemption, the right to exercise the Rights will terminate and the only right
of the holders of Rights will be to receive the Redemption Price.

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the
right to vote or to receive dividends.

         For so long as the Rights are then redeemable, the Company may, except
with respect to the redemption price, amend the Rights Agreement in any manner.
After the Rights are no longer redeemable, the Company may, except with respect
to the redemption price, amend the Rights Agreement in any manner that does not
adversely affect the interests of holders of the Rights.

COMMON STOCK

   
         The Company is authorized to issue 35,000,000 shares of Common Stock,
par value $.01, of which [16,515,038] were issued and outstanding at September
1, 1998.  Holders of Common Stock are entitled to one vote for each share held.
Shareholders do not have preemptive rights or the right to cumulate votes for
the election of directors.  Shares are not subject to redemption nor to any
liability for further calls.  All shares of Common Stock issued and outstanding
are, and all the shares issued on conversion of the Notes offered by the
Company hereby when issued will be, validly issued, fully paid and
non-assessable.  Holders of the Common Stock are entitled to receive dividends
as they are declared by the Board of Directors out of funds legally available
therefor and are entitled to participate in the assets of the Company available
for distribution in the event of  liquidation or dissolution.  See "Price Range
of Common Stock and Dividend Policy."  At September 1, 1998, there were
[3,192,933] shares, in the aggregate, reserved for issuance under the Company's
stock option or employee benefits plans, of which [1,822,987], in the
aggregate, were subject to outstanding options.  No shares were reserved for
issuance upon the exercise of outstanding options granted outside the Company's
option plans.  The Company does not currently have any plans to issue
additional shares of Common Stock other than pursuant to its 1990 Stock
Compensation Plan, its 1990 Non-Qualified Plan or its Employee Stock Purchase
Plan.
    

ANTITAKEOVER MEASURES

         The Board of Directors adopted amendments ("Antitakeover Measures") to
the Company's bylaws on August 14, 1995, designed to protect shareholders'
rights in the event of an acquisition of control by an outsider that does not
have the support of the Board of Directors.  The primary amendment classifies
the Board of Directors.  Other Antitakeover Measures adopted by the Board of
Directors include







                                      153
<PAGE>   170

supermajority approval by the shareholders for (i) sale of substantially all of
the assets of the Company, merger or issuances of stock to certain shareholders
unless approved by Continuing Directors (as herein defined); (ii) removal of
directors; and (iii) amendment or repeal of Antitakeover Measures.  The
Antitakeover Measures could result in a denial or reduction to shareholders of
potential premiums over market often afforded by tender offers, the ability of
management or less than a majority of shareholders to thwart transactions which
may be desirable or beneficial to shareholders and increased difficulty to
alter management of the Company.

         As amended, the bylaws provide that the Board of Directors shall
consist of seven (7) directors, and the number may be increased or decreased by
a majority of the Continuing Directors, provided that the number of directors
shall never be less than three (3) nor more than nine (9) members.  Under the
amended bylaws, at the Annual Meeting held on May 14, 1996, two directors were
elected to serve terms expiring at the 1997 Annual Meeting, three directors
were elected to serve terms expiring at the 1998 Annual Meeting, and two
directors were elected to serve terms expiring at the 1999 Annual Meeting of
shareholders.  In all cases, the directors will hold office until their
respective successors have been duly elected and have qualified.  Vacancies
occurring on the Board of Directors may be filled by the Board of Directors for
the unexpired term of the replacement director's predecessor in office.  At
future annual meetings, each nominee for director that is elected will be
elected to serve a three year term.

         The Antitakeover Measures also provide for the affirmative vote of at
least sixty-six and two thirds percent (66-2/3%) of the outstanding shares of
the capital stock of the Company entitled to vote generally in the election of
directors ("Supermajority Vote") on certain corporate actions.  A Supermajority
Vote is required to sell, assign or dispose of the Company's assets or to merge
with another corporation or entity if such transaction is not approved by a
majority of the directors then in office who were directors for the two-year
period ending on the date notice of the meeting or written consent is first
provided to shareholders (the "Continuing Directors") or to enter into any
transaction, including the issuance or transfer of securities of the Company,
to any holder of twenty percent (20%) of the outstanding capital stock of the
Company.  A Supermajority Vote is also required to remove one or more directors
or to amend or repeal the provisions that contain Antitakeover Measures in the
bylaws adopted by the Board of Directors.

<PAGE>   173

MMBTU means million British thermal units, which is a heating equivalent
measure for natural gas and is an alternate measure of natural gas reserves, as

demonstrate with reasonable certainty to be recoverable in future years from
known reservoirs under existing economic and operating conditions, that is,
prices and costs as of the date the estimate is made.

PV-10 VALUE means, in accordance with the Commission guidelines, the estimated
future net cash flow 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 services, future income, tax expenses
or depreciation, depletion and amortization.

PETROLEUM ENGINEERING CONSULTANTS means the independent petroleum engineering
firms of H. J. Gruy & Associates, Inc. and J. R. Butler & Company, both located

non-operating interests.  Producing Properties may include gas gathering lines
or pipelines.  The geographical limits of a Producing Property may be enlarged
or contracted on the basis of subsequently acquired geological data to define
the productive limits of a reservoir, or as a result of action by a regulatory
agency employing such criteria as the regulatory agency may determine.

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

RESERVE REPLACEMENT COST means, with respect to proved reserves, a three-year
average (unless otherwise indicated) calculated by dividing total incurred
acquisition, exploration and development costs (exclusive of future development
costs) by net reserves added during the period.

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.

VOLUMETRIC PRODUCTION PAYMENT means the 1992 agreement pursuant to which the
Company financed the purchase of certain oil and natural gas interests and
committed to deliver certain monthly quantities of natural gas.

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.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders and Board of Directors of Swift Energy Company:
 
   
     We have audited the accompanying consolidated balance sheets of Swift
Energy Company (a Texas corporation) and subsidiaries as of December 31, 1997
and 1996, and the related consolidated statements of income, stockholders'
equity, and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these combined
financial statements based on our audits.
    
 
   
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall combined financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
    
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Swift Energy Company and
subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
   
     Principles of Consolidation. The accompanying consolidated financial
statements include the accounts of Swift Energy Company (Swift) and its wholly
owned subsidiaries (collectively referred to as the "Company"), which are
engaged in the acquisition, development, operation, and exploration of oil and
natural gas properties, with particular emphasis on U.S. onshore natural gas
reserves. The Company also has oil and gas investments in Russia, Venezuela, and
New Zealand. The Company's investments in associated oil and gas partnerships
and its joint ventures are accounted for using the proportionate consolidation
method, whereby the Company's proportionate share of each entity's assets,
liabilities, revenues, and expenses is included in the appropriate
classifications in the consolidated financial statements. Intercompany balances
and transactions have been eliminated in preparing the consolidated statements.
In the second quarter 1998, the Company began netting supervision fees against
general and administrative expenses and oil and gas production costs. This
reclassification has been made to all periods presented. Certain other
reclassifications have been made to prior year amounts to conform to the current
year presentation.
    
 
   
     Unaudited Interim Information. The unaudited interim consolidated financial
statements as of June 30, 1998 and for each of the six month periods ended June
30, 1998 and 1997, included herein, have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim consolidated financial statements
include all adjustments (consisting only of normal recurring adjustments) to
present fairly the information set forth herein. The interim financial results
should not be regarded as indicative of operating results for an entire year.
    
 
     Use of Estimates. The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities, if any, at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from
estimates.
 
     Property and Equipment. The Company follows the "full-cost" method of
accounting for oil and gas property and equipment costs. Under this method of
accounting, all productive and nonproductive costs incurred in the acquisition,
exploration, and development of oil and gas reserves are capitalized. Such costs
include lease acquisitions, geological and geophysical services, drilling,
completion, equipment, and certain general and administrative costs directly
associated with acquisition, exploration, and development activities. General
and administrative costs related to production and general overhead are expensed
as incurred. No gains or losses are recognized upon the sale or disposition of
oil and gas properties, except in transactions that involve a significant amount
of reserves. The proceeds from the sale of oil and gas properties are generally
treated as a reduction of oil and gas property costs. Fees from associated oil
and gas exploration and development limited partnerships are credited to oil and
gas property costs to the extent they do not represent reimbursement of general
and administrative expenses currently charged to expense.
 
     Future development, site restoration, and dismantlement and abandonment
costs, net of salvage values, are estimated on a property-by-property basis
based on current economic conditions and are amortized to expense as the
Company's capitalized oil and gas property costs are amortized. The Company's
properties are all onshore and historically the salvage value of the tangible
equipment offsets the Company's site restoration and dismantlement and
abandonment costs. The Company expects this relationship will continue.
 
     The Company computes the provision for depreciation, depletion, and
amortization of oil and gas properties on the unit-of-production method. Under
this method, the Company computes the provision by multiplying the total
unamortized costs of oil and gas properties -- including future development,
site restoration, and dismantlement and abandonment costs but excluding costs of
unproved properties -- by an

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
overall rate determined by dividing the physical units of oil and gas produced
during the period by the total estimated units of proved oil and gas reserves.
This calculation is done on a country by country basis for those countries with
oil and gas production. The Company currently has production in the United
States only. The cost of unproved properties not being amortized is assessed
quarterly to determine whether the value has been impaired below the capitalized
cost. Any impairment assessed is added to the cost of proved properties being
amortized. To the extent costs accumulated in the Company's international
initiatives will not result in the addition of proved reserves, an impairment
would be charged to income upon such determination.
 
     At the end of each quarterly reporting period, the unamortized cost of oil
and gas properties, net of related deferred income taxes, is limited to the sum
of the estimated future net revenues from proved properties using current
prices, discounted at 10%, and the lower of cost or fair value of unproved
properties, adjusted for related income tax effects ("Ceiling Limitation"). This
calculation is done on a country by country basis for those countries with
proved reserves. Currently, the Company has proved reserves in the United States
only.
 
     The calculation of the Ceiling Limitation and provision for depreciation,
depletion, and amortization is based on estimates of proved reserves. There are
numerous uncertainties inherent in estimating quantities of proved reserves and
in projecting the future rates of production, timing, and plan of development.
The accuracy of any reserves 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. Accordingly, reserves estimates are often
different from the quantities of oil and gas that are ultimately recovered.
 
     All other equipment is depreciated by the straight-line method at rates
based on the estimated useful lives of the property. Repairs and maintenance are
charged to expense as incurred. Renewals and betterments are capitalized.
 
     Oil and Gas Revenues. Gas revenues generally are recorded using the
entitlement method in which the Company recognized its ownership interest in
natural gas production as revenue. If the Company's sales exceed its ownership
share of production, the differences are recorded as deferred revenue. Natural
gas balancing receivables are recorded when the Company's ownership share of
production exceeds sales. As of December 31, 1997 the Company did not have any
material natural gas imbalances.
 
     Deferred Charges. Legal and accounting fees, underwriting fees, printing
costs, and other direct expenses associated with the issuance of the Company's
6.5% Convertible Subordinated Debentures due 2003 ("Debentures") were
capitalized in June 1993 and through June 1996 were being amortized over the
life of the Debentures. Due to the conversion of all outstanding Debentures into
common stock in August 1996, the related unamortized costs ($1,097,551) were
transferred to the Company's appropriate capital accounts in the third quarter
of 1996. The issuance costs associated with the public offering in November 1996
of the Company's 6.25% Convertible Subordinated Notes (the "Notes") have been
capitalized and are being amortized, using the effective interest method, over
the life of the Notes, which mature on November 15, 2006. The balance of these
issuance costs at December 31, 1997, ($4,184,014) is net of accumulated
amortization of $365,986.
 
     Limited Partnerships and Joint Ventures. Between 1991 and 1995 (and for
prior periods), the Company formed limited partnerships and joint ventures for
the purpose of acquiring interests in producing oil and gas properties and,
since 1993, partnerships engaged in drilling for oil and gas reserves. The
Company serves as managing general partner or manager of these entities. Because
the Company serves as the general partner of these entities, under state
partnership law it is contingently liable for the liabilities of these
partnerships, virtually all of which are owed to the Company and are not
material for any of the periods presented in relation to the partnerships'
respective assets.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company acquired producing oil and gas properties and transferred those
properties to the partnership entities which invested in producing oil and gas
properties at cost, including interest, other carrying costs, closing costs, and
screening and evaluation costs of properties not acquired, or in certain
instances at fair market value based upon the opinion of an independent expert.
These costs were reduced by net operating revenues from the effective date of
the acquisition to the date of transfer to these entities. Such net operating
revenue amounts totaled approximately $100,000, $300,000, and $600,000 in 1997,
1996, and 1995, respectively. The Company, with the acquisitions made in 1997,
has fulfilled its responsibility of acquiring properties for such partnerships,
as these partnerships are fully invested in properties.
 
     Commencing September 15, 1993, the Company began offering, on a private
placement basis, general and limited partnership interests in limited
partnerships to be formed to drill for oil and gas. As managing general partner,
the Company pays for all front-end costs incurred in connection with these
offerings, for which the Company receives an interest in the partnerships.
Through December 31, 1997, approximately $58.6 million had been raised in eleven
partnerships, one formed in each of 1993 and 1994 and three in each of 1995,
1996, and 1997. In May, July, and September 1997, the Company closed the ninth,
tenth, and eleventh partnerships with total subscriptions of approximately $4.4
million, $3.0 million, and $9.4 million, respectively. Costs of syndication and
qualification of these limited partnerships incurred by the Company have been
deferred. Under the current private limited partnership offerings, selling and
formation costs borne by the Company serve as the Company's general partner
contribution to such partnerships.
 
     During 1996, the limited partners in 18 partnerships, which had been in
operation over nine years and had produced a substantial majority of their
reserves, voted to sell their remaining properties and liquidate the limited
partnerships. Of these partnerships, 10 were the earliest public income
partnerships (formed in 1984 to 1986) and were liquidated in 1996, and in early
1997 eight private drilling partnerships (formed in 1979 to 1985) were
liquidated. During 1997, the limited partners in an additional 11 partnerships,
formed in 1990 and 1991, voted to sell their properties and liquidate the
limited partnerships, which liquidation is expected in early 1998. As the public
income partnerships formed since 1986 grow older, it is anticipated that
proposals will continue to be made to the investors in those partnerships to
sell their properties and liquidate the partnerships.
 
     Hedging Activities. The Company's revenues are primarily the result of
sales of its oil and natural gas production. Market prices of oil and natural
gas may fluctuate and adversely affect operating results. To mitigate some of
this risk, the Company does engage periodically in certain limited hedging
activities, but only to the extent of buying protection price floors for
portions of its and the limited partnerships' oil and gas production. Costs and
any benefits derived from these price floors are accordingly recorded as a
reduction or increase, as applicable, in oil and gas sales revenue and were not
significant for any year presented. The costs to purchase put options are
amortized over the option period. The costs related to the open contracts
totaled approximately $95,308 and had a market value of $121,600 as of December
31, 1997.
 
     Income Taxes. The Company accounts for income taxes using Statement of
Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes."
SFAS No. 109 utilizes the liability method, and deferred taxes are determined
based on the estimated future tax effects of differences between the financial
statement and tax bases of assets and liabilities given the provisions of the
enacted tax laws.
 
     Deferred Revenues. In May 1992, the Company purchased interests in certain
wells using funds provided by the Company's sale of a volumetric production
payment in these properties. Under the production payment agreement, the Company
is required to deliver to Enron approximately 9.5 Bcf over an eight-year period,
or for such longer period as is necessary to deliver a specified heating
equivalent quantity at an average price of $1.115 per MMBtu. The Company is
responsible for all production-related costs associated with operating these
properties. The amount to be delivered varies from month to month in generally
decreasing quantities. To the extent monthly gas production from the properties
exceeds the agreed upon deliverable quantities (as it has in every year since
the purchase date), the Company receives all proceeds from sale of such excess
gas at

current market prices plus the proceeds from sale of oil or condensate. Volumes
remaining to be delivered through October 2000 under the volumetric production
payment (approximately 2.0 Bcf at December 31, 1997) are not included in the
Company's proved reserves. Net proceeds from the sale of the production payment
were recorded as deferred revenues. Deliveries under the production payment
agreement are recorded as oil and gas sales revenues and a corresponding
reduction of deferred revenues. Hydrocarbons produced in excess of the amount
required to be delivered are sold by the Company for its own account.
 
     Cash and Cash Equivalents. The Company considers all highly liquid debt
instruments with an initial maturity of three months or less to be cash
equivalents.
 
     Credit Risk Due to Certain Concentrations. The Company extends credit,
primarily in the form of monthly oil and gas sales and joint interest owners
receivables, to various companies in the oil and gas industry, which results in
a concentration of credit risk. The concentration of credit risk may be affected
by changes in economic or other conditions and may accordingly impact the
Company's overall credit risk. However, the Company believes that the risk of
these unsecured receivables is mitigated by the size, reputation, and nature of
the companies to which the Company extends credit.
 
     During the year ended December 31, 1997, three oil or gas purchasers each
accounted for 10% or more of the Company's revenues, with those purchasers
together accounting for approximately 42%. Three oil or gas purchasers accounted
for 10% or more of the Company's revenues during the year ended December 31,
1996, with those purchasers together accounting for approximately 51%. Because
of the availability of other purchasers, the Company does not believe that the
loss of any single oil or gas purchaser or contract would materially affect its
sales.
 
     Fair Value of Financial Instruments. The Company's financial instruments
consist of cash and cash equivalents, accounts receivable, accounts payable, and
long-term debt. The carrying amounts of cash and cash equivalents, accounts
receivable, and accounts payable approximate fair value due to the highly liquid
nature of these short-term instruments. The fair value of long-term debt was
determined based upon interest rates currently available to the Company for
borrowings with similar terms. The fair value of long-term debt approximates the
carrying amount as of December 31, 1997.
 
     New Accounting Pronouncements. In the first quarter of 1998, the Company
adopted SFAS No. 130, "Reporting Comprehensive Income," which requires the
display of comprehensive income and its components in the financial statements.
Comprehensive income represents all changes in equity during the reporting
period, including net income and charges directly to equity which are excluded
from net income. The adoption of this statement does not have a material impact
on the Company or its financial disclosures, as the Company has not historically
and currently does not enter into transactions which result in charges (or
credits) directly to equity (such as additional minimum pension liability
changes, currency translation adjustments, and unrealized gains and losses on
available for sale securities.)
 
     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities," which requires costs of start-up activities to be expensed as
incurred. The statement is effective for financial statements beginning after
December 15, 1998. The Company expects to expense currently capitalized costs
related to start-up activities as a cumulative effect of a change in accounting
principle when the statement is adopted in January 1999. The adoption of this
standard is not expected to have a significant effect on the Company's financial
position or results of operations.
 
     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." The Statement
establishes accounting and reporting standards requiring that every derivative
instrument (including certain derivative instruments embedded in other
contracts) be recorded in the balance sheet as either an asset or liability
measured at its fair value. SFAS No. 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allow as derivative's gains

and losses to offset related results on the hedged item in the income statement,
and requires that a company must formally document, designate, and assess the
effectiveness of transactions that receive hedge accounting.
 
     SFAS No. 133 is effective for fiscal years beginning after June 15, 1999. A
company may also implement SFAS No. 133 as of the beginning of any fiscal
quarter after issuance (that is, fiscal quarters beginning June 16, 1998 and
thereafter). SFAS No. 133 cannot be applied retroactively. SFAS No. 133 must be
applied to (a) derivative instrument and (b) certain derivative instruments
embedded in hybrid contracts that were issued, acquired, or substantively
modified after December 31, 1997 (and, at the Company's election, before January
1, 1998).
 
     The Company has not yet quantified the impacts of adopting SFAS No. 133 on
its financial statements and has not determined the timing of or method of our
adoption of SFAS No. 133.
 
2. INCOME PER SHARE
 
     The Company has adopted SFAS No. 128, "Earnings per Share," which
establishes new standards for computing and presenting earnings per share. Basic
income per share has been computed using the weighted average number of common
shares outstanding during the respective periods. Basic income per share has
been retroactively restated in all periods presented to give recognition to the
adoption of SFAS No. 128, as well as to give recognition to an equivalent change
in capital structure as a result of a 10% stock dividend declared in October
1997 that resulted in an additional 1,494,606 shares being issued.
 
     The calculation of diluted income per share assumes conversion of the
Company's Notes as of the beginning of the respective periods and the
elimination of the related after-tax interest expense and assumes, as of the
beginning of the period, exercise (using the treasury stock method) of stock
options and warrants. Diluted income per share has also been retroactively
restated for all periods presented to give effect to the adoption of SFAS No.
128 and the 10% stock dividend. For periods presented in which the Notes were
outstanding, the original conversion price of $34.6875 was revised to $31.534 to
reflect the October 1997 stock dividend declared.
 
   
     The following is a reconciliation of the numerators and denominators used
in the calculation of basic and diluted earnings per share for the years ended
December 31, 1997, 1996, 1995, and for the six months ended June 30, 1998 and
1997:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company did not record any valuation allowances against deferred tax
assets at December 31, 1997, 1996, and 1995.
 
     At December 31, 1997, the Company had alternative minimum tax credits of
$1,831,299 that carry forward indefinitely available to reduce future regular
tax liability to the extent they exceed the related tentative minimum tax
otherwise due.
 
4. LONG-TERM DEBT AND BANK BORROWINGS
 
     Long-Term Debt. The Company's long-term debt at December 31, 1997 and 1996,
consists of $115,000,000 of 6.25% Convertible Subordinated Notes due 2006
("Notes"). The Notes were issued on November 25, 1996, and will mature on
November 15, 2006. The Notes are convertible into common stock of the Company at
the option of the holders at any time prior to maturity at an adjusted
conversion price of $31.534 per share, subject to adjustment upon the occurrence
of certain events. The original conversion price of $34.6875 was adjusted
downward to reflect the October 1997 10% stock dividend. Interest on the Notes
is payable semiannually on May 15 and November 15, commencing with the first
payment on May 15, 1997. On or after November 15, 1999, the Notes are redeemable
for cash at the option of the Company, with certain restrictions, at 104.375% of
principal, declining to 100.625% in 2005. Upon certain changes in control of the
Company, if the price of the Company's common stock is not above certain levels,
each holder of Notes will have the right to require the Company to repurchase
the Notes at the principal amount thereof, together with accrued and unpaid
interest to the date of repurchase but after the repayment of any Senior
indebtedness, as defined.
 
     The Company's long-term debt previously consisted of $28,750,000 of 6.5%
Convertible Subordinated Debentures due 2003 ("Debentures") issued on June 30,
1993, which were convertible into common stock of the Company at an adjusted
conversion price of $12.27 per share. On July 1, 1996, the Company called all of
the Debentures for redemption on August 5, 1996, at 104.55% of their face
amount. Prior to the redemption date, the holders of all of the outstanding
Debentures elected to convert their Debentures into shares of common stock,
resulting in the issuance of 2.34 million shares of common stock in August 1996.
Upon conversion of the Debentures into common stock, the approximate $27,650,000
net carrying amount of the debt (the face amount less unamortized deferred
charges) was transferred to the Company's appropriate capital accounts during
the third quarter of 1996.
 
     Interest expense on the Notes, including amortization of debt issuance
costs, totaled $7,514,967 in 1997, while interest expense on both the Notes and
Debentures, including amortization of debt issuance costs, totaled $1,731,194 in
1996.
 
     Bank Borrowings. At the end of 1996, the Company had available, through a
two bank-group, a $100,000,000 unsecured revolving line of credit. The available
borrowing base at December 31, 1996, was $5,000,000. Prior to December 1, 1996,
the borrowing base was $30,000,000. At the Company's request, it was reduced to
the $5,000,000 amount effective December 1, 1996. This was requested in order to
reduce the amount of commitment fees paid on this facility, the calculation of
which is described below. Depending on the level of outstanding debt, the
interest rate is either the bank's base rate (8.25% at December 31, 1996) or the
bank's base rate plus 0.25%. This facility also allows, at the Company's option,
draws which bear interest for specific periods at the London Interbank Offered
Rate ("LIBOR"). The LIBOR option will now vary from LIBOR plus 1% to plus 1.5%.
There was no outstanding balance under this line of credit at December 31, 1996.
 
     Effective December 1, 1997, the available borrowing base was increased to
$40,000,000 and will be redetermined periodically. The interest rate was 8.5% at
December 31, 1997, with an outstanding balance at that date of $2,431,000. The
revolving line of credit extends through September 30, 1999.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The terms of the revolving line of credit include, among other
restrictions, a limitation on the level of cash dividends (not to exceed
$2,000,000 in any fiscal year), requirements as to maintenance of certain
minimum financial ratios (principally pertaining to working capital, debt, and
equity ratios), and limitations on incurring other debt. Since inception, no
cash dividends have been declared on the Company's common stock. For all periods
presented, the Company was in compliance with the provisions of these
agreements.
 
     The Company's other credit facility, which is the Company's only secured
facility, is an amended and restated revolving line of credit with the lead bank
of the two bank-group, secured by certain Company receivables. Effective April
30, 1996, this facility was increased to $7,000,000, with interest at the bank's
base rate less 0.25% (8% at December 31, 1996 and 8.25% at December 31, 1997).
The available borrowing base was $2,000,000 at December 31, 1996, and $5,484,000
at December 31, 1997, and is redetermined monthly. There were no outstanding
amounts under this facility at December 31, 1996, while at December 31, 1997,
the outstanding amount was $5,484,000. The restated credit facility extends
through September 30, 1999.
 
     In addition to interest on these credit facilities, the Company pays a
commitment fee to compensate the banks for making funds available. The fee on
the revolving line of credit is calculated on the average daily remainder, if
any, of the commitment amount less the aggregate principal amounts outstanding,
plus the amount of all letters of credit outstanding during the period. The
aggregate amounts of commitment fees paid by the Company were $31,000 in 1997
and $120,000 in 1996.
 
5. COMMITMENTS AND CONTINGENCIES
 
     Total rental and lease expenses were $1,039,210 in 1997, $957,797 in 1996,
and $998,714 in 1995. The Company's remaining minimum annual obligations under
non-cancelable operating lease commitments are $1,136,523 for 1998, $1,175,546
for 1999, $1,181,455 for 2000, $1,181,455 for 2001, and $1,303,130 for 2002.
 
     As of December 31, 1997, the Company is the managing general partner of 89
limited partnerships. Because the Company serves as the general partner of these
entities, under state partnership law it is contingently liable for the
liabilities of these partnerships, which liabilities are not material for any of
the periods presented in relation to the partnerships' respective assets.
 
     In the ordinary course of business, the Company has been party to various
legal actions, which arise primarily from its activities as operator of oil and
gas wells. In management's opinion, the outcome of any such currently pending
legal actions will not have a material adverse effect on the financial position
or results of operations of the Company.
 
6. STOCKHOLDERS' EQUITY
 
     Common Stock. In October 1997, the Company declared a 10% stock dividend to
shareholders of record. The transaction was valued based on the closing price
($28.8125) of the Company's common stock on the New York Stock Exchange on
October 1, 1997. As a result of the issuance of 1,494,606 shares of the
Company's common stock as a dividend, retained earnings were reduced by
$43,063,335, with the common stock and additional paid-in capital accounts
increased by the same amount. Basic and diluted income per share was restated
for all periods presented to reflect the effect of the stock dividend.
 
     In August 1996, the holders of the Company's Debentures converted such
Debentures into 2,343,108 shares of the Company's common stock, which resulted
in a third quarter 1996 increase in the Company's capital accounts of
approximately $27,650,000.
 
     Stock-Based Compensation Plans. The Company has two stock option plans, the
1990 stock compensation plan and the 1990 nonqualified plan, as well as an
employee stock purchase plan.
 
     Under the 1990 compensation plan, incentive stock options and other options
and awards may be granted to employees to purchase shares of common stock. Under
the 1990 non-qualified plan, non-employee
                                      F-14

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
members of the Company's Board of Directors may be granted options to purchase
shares of common stock. Both plans provide that the exercise prices equal 100%
of the fair value of the common stock on the date of grant. Options become
exercisable for 20% of the shares on the first anniversary of the grant of the
option and are exercisable for an additional 20% per year thereafter. Options
granted expire 10 years after the date of grant or earlier in the event of the
optionee's separation from employment. At the time the stock options are
exercised, the option price is credited to common stock and additional paid-in
capital.
 
     The Company also granted certain stock options to individuals who were
neither employees, officers, nor directors for specific services rendered to the
Company. During 1996 all of these remaining options were either exercised
(57,555 shares) or canceled (11,195 shares) so that no such options remain
outstanding.
 
     The employee stock purchase plan provides eligible employees the
opportunity to acquire shares of Company common stock at a discount through
payroll deductions. This plan was approved at the May 11, 1993, shareholders
meeting. The plan year is from June 1 to the following May 31. The first year of
the plan commenced June 1, 1993. Employees may authorize payroll deductions of
up to 10% of their base salary during the plan year by making an election to
participate prior to the start of a plan year. The purchase price for stock
acquired under the plan will be 85% of the lower of the closing price of the
Company's common stock as quoted on the New York Stock Exchange at the beginning
or end of the plan year or a date during the year chosen by the participant.
Under this plan the Company issued 26,551 shares at a price of $15.19 in 1997,
36,387 shares at a price range of $6.59 to $7.97 in 1996, and 37,689 shares at a
price range of $6.80 to $7.92 in 1995. The estimated weighted average fair value
of shares issued under this plan was $4.39 in 1997, $2.13 in 1996, and $2.59 in
1995. As of December 31, 1997, there remained 458,204 shares available for
issuance under this plan. There are no charges or credits to income in
connection with this plan.
 
     The Company accounts for the two stock option plans under APB Opinion No.
25, under which no compensation cost has been recognized. Had compensation cost
for these plans been determined consistent with SFAS No. 123, "Accounting for
Stock-Based Compensation," the Company's net income and earnings per share would
have been reduced to the following pro forma amounts (1996 and 1995 amounts have
been restated to reflect the October 1997 10% stock dividend):

</TABLE>
 
     Because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of that to be expected in future years.

     Employee Stock Ownership Plan. In 1996, the Company established an Employee
Stock Ownership Plan ("ESOP") effective January 1, 1996. All employees over the
age of 21 with one year of service are participants. The Plan has a five year
cliff vesting, and service is recognized after the Plan effective date. The ESOP
is designed to enable employees of the Company to accumulate stock ownership.
While there will be no employee contributions, participants will receive an
allocation of stock which has been contributed by the Company. Compensation
costs are reported when such shares are released to employees. The Plan may also
acquire Swift Energy Company common stock purchased at fair market value. The
ESOP can borrow money from the Company to buy Company stock. This was done in
September 1996 to purchase 25,000 shares (adjusted to 27,500 shares after the
October 1, 1997 10% stock dividend) from the Company's chairman. Benefits will
be paid in a lump sum or installments, and the participants generally have the
choice of receiving

cash or stock. At December 31, 1997 and 1996, the unearned portion of the ESOP
($150,055) and ($521,354), respectively, was recorded as a contra-equity account
entitled "Unearned ESOP Compensation."
 
     Common Stock Repurchase Program. In March 1997, the Company's Board of
Directors approved a common stock repurchase program for up to $20.0 million of
the Company's common stock and subsequently extended this program through June
30, 1998. Purchases of shares are made in the open market. Under the program,
through December 31, 1997, 387,800 shares have been acquired at a total cost of
$8,519,665 and are included in "Treasury stock held, at cost" on the balance
sheet.
 
     Shareholder Rights Plan. In August 1997, the Board of Directors declared a
dividend of one preferred share purchase right on each outstanding share of the
Company's common stock. The rights are not currently exercisable, but would
become exercisable if certain events occurred relating to any person or group
acquiring or attempting to acquire 15% or more of the Company's outstanding
shares of common stock. Thereafter, upon certain triggers, each right not owned
by an acquiror allows its holder to purchase Company securities with a market
value of two times the $150 exercise price.
 
7. RELATED-PARTY TRANSACTIONS
 
     The Company is the operator of a substantial number of properties owned by
its affiliated limited partnerships and joint ventures and accordingly charges
these entities and third party joint interest owners operating fees. The Company
is also reimbursed for direct, administrative, and overhead costs incurred in
conducting the business of the limited partnerships, which totaled approximately
$6,300,000, $6,100,000, and $4,800,000 in 1997, 1996, and 1995, respectively.
The Company was also reimbursed by the limited partnerships and joint ventures
for costs incurred in the screening, evaluation, and acquisition of producing
oil and gas properties on their behalf. Such costs totaled approximately
$490,000, $250,000, and $600,000 in 1997, 1996, and 1995, respectively. In the
case where the limited partners voted to sell their remaining properties and
liquidate the limited partnerships, the Company was also reimbursed for direct,
administrative, and overhead costs incurred in the disposition of such
properties, which costs totaled approximately $675,000, $805,000, and $80,000 in
1997, 1996, and 1995, respectively.
 
8. FOREIGN ACTIVITIES
 
     On September 3, 1993, the Company signed a Participation Agreement with
Senega, a Russian Federation joint stock company (in which the Company has an
indirect interest of less than 1%), to assist in the development and production
of reserves from two fields in Western Siberia providing the Company with a
minimum 5% net profits interest from the sale of hydrocarbon products from the
fields for providing managerial, technical, and financial support to Senega.
Additionally, the Company purchased a 1% net profits interest from Senega for
$300,000. In May 1995, the Company executed a Management Agreement with Senega,
under which, in return for undertaking to obtain financing for development of
these fields, Swift would be entitled to receive a 49% interest in production
income derived by Senega from this project after repayment of costs.
 
     On December 10, 1997, the Company agreed to terminate the Management
Agreement with Senega and to amend and restate the Participation Agreement.
Under the amended and restated Participation Agreement, the Company retains its
6% net profits interest in the Samburg Field and has agreed to assist Senega in
obtaining investments necessary to develop the field. Senega is charged with the
management and control of the field development. At December 31, 1997, the
Company's investment in Russia was approximately $10,190,000 and is included in
the unproved properties portion of oil and gas properties.
 
     The Company formed a wholly-owned subsidiary, Swift Energy de Venezuela, C.
A., for the purpose of submitting a bid on August 5, 1993, under the Venezuelan
Marginal Oil Field Reactivation Program. Although the Company did not win the
bid, it has continued to pursue cooperative ventures involving other fields and
opportunities in Venezuela. The Company evaluated a number of Blocks being
offered by Petroleos

de Venezuela, S. A. under the Third Operating Agreement Round in 1997, but
decided against submitting any bid on these Blocks. The Company has entered into
an agreement with Tecnoconsult, S. A., a Venezuelan company, to jointly
formulate and submit a proposal to Petroleos de Venezuela, S. A. for the
construction and operation of a methane pipeline. Currently, the technical and
economic feasibility of the project is under study. At December 31, 1997, the
Company's investment in Venezuela was approximately $2,435,000 and is included
in the unproved properties portion of oil and gas properties, net of impairments
of $45,668.
 
     Since October 1995, the Company has been issued two Petroleum Exploration
Permits by the New Zealand Minister of Energy. The first permit covers
approximately 65,000 acres in the Onshore Taranaki Basin of New Zealand's North
Island, and the second covers approximately 69,300 adjacent acres. Under the
terms of these permits, the Company is obligated to analyze and interpret
certain seismic data, acquire certain new seismic data and drill one exploratory
well, to be followed by a development well or additional seismic work, all of
which is to be performed on a staged basis in order to maintain the permits,
over periods extending through July 2000 for the first permit and August 1999
for the second permit. The Company formed a wholly-owned subsidiary, Swift
Energy New Zealand Limited, for the purpose of conducting its New Zealand
activities and assigned its interest in the permits to that subsidiary during
the third quarter of 1997. At December 31, 1997, the Company's investment in New
Zealand was approximately $2,480,000 and is included in the unproved properties
portion of oil and gas properties.
 
   
(9) SUBSEQUENT EVENTS (SUBSEQUENT TO THE DATE OF AUDITOR'S REPORT AND UNAUDITED)
    
 
   
     Sonat Properties Acquisition. On July 2, 1998, the Company entered into a
purchase agreement to acquire from Sonat Exploration Company ("Sonat"), a
subsidiary of Sonat Inc., effective April 1, 1998, certain producing oil and gas
properties (the "Sonat Properties") located in the Texas and Louisiana Austin
Chalk trend for approximately $87.6 million in cash, with a majority of the
purchase price being allocated to proved reserves. As of April 1, 1998,
estimated proved reserves for the Sonat Properties were 91.1 Bcfe, of which
approximately 56% was natural gas, with 1997 production of 22.0 Bcfe, of which
approximately 51% was natural gas. The properties include 156 producing oil and
natural gas wells in the Brookeland Field in Southeast Texas and the Masters
Creek Field in Western Louisiana, 21 saltwater disposal wells, a 20% interest in
two natural gas plants, associated production facilities and working interests
in approximately 200,000 undeveloped net acres containing more than 50 drilling
locations. The Company will become operator of 113 of the 156 wells. The two gas
plants are outside operated and have combined capacity of 250 Mmcfe per day, and
in 1997 had operating cash flow of $2.8 million. The acquisition was closed on
August 26, 1998.
    
 
   
     New Credit Facility. On August 18, 1998, the Company closed on a $250.0
million revolving line of credit (the "New Credit Facility"), of which Bank One,
Texas, National Association, the lead bank, has committed $37.5 million and has
syndicated the balance with a group of nine other banks. The New Credit Facility
is subject to an initial borrowing base of $170.0 million. However, an
additional $30.0 million will be added to this borrowing base upon consummation
of the acquisition of the Partnership Properties. As of September 1, 1998, $19.2
million of the $170.0 million borrowing base was available to the Company. The
New Credit Facility replaces all of the Company's prior bank credit facilities.
The borrowing base will be redetermined semi-annually on the basis of reserve
reports and other information available to the lenders. In addition, the lenders
or the Company may, at their discretion, make a redetermination of the borrowing
base at any time including in connection with the incurrence of additional debt
and the sale or transfer of properties by the Company.
    
 
   
     Borrowings under the New Credit Facility bear interest, at the option of
the Company, either at (i) the lead bank's prime rate, currently 8.5%, or (ii)
adjusted LIBOR plus the applicable margin, which increases as the level of
outstanding debt increases. The New Credit Facility extends until August 18,
2002. The terms of the New Credit Facility include restrictions such as
limitations on debt obligations, certain liens, dividends (not to exceed $2.0
million annually), a $15.0 million limit on repurchases by the Company of its
Common Stock, as well requirements as to maintenance of certain minimum
financial ratios (principally pertaining to working capital, debt and equity
ratios).

     Of the $26,735,460 of net domestic unproved property costs (primarily
seismic and lease acquisition costs) at December 31, 1997, being excluded from
the amortizable base, $16,902,647 was incurred in 1997, $5,244,450 was incurred
in 1996, $1,262,038 was incurred in 1995, and $3,326,325 was incurred in prior
years. The Company expects it will complete its evaluation of the properties
representing the majority of these domestic costs within the next two to three
years.
 
     Of the $15,104,349 of net foreign unproved property costs at December 31,
1997, being excluded from the amortizable base, $3,217,838 was incurred in 1997,
$3,745,856 was incurred in 1996, $3,321,211 was incurred in 1995, and $4,819,444
was incurred in prior years. In New Zealand, the Company expects drilling to
commence in either late 1998 or in 1999. At this time the Company cannot predict
when it will complete the evaluation of its unproved properties in Russia and
Venezuela due to various economic and political factors associated with such
investments.

(2) Revisions of previous quantity estimates are related to upward or downward
    variations based on current engineering information for production rates,
    volumetrics, and reservoir pressure. Additionally, changes in quantity
    estimates are affected by the increase or decrease in crude oil and natural
    gas prices at each year end. Proved reserves as of December 31, 1997, were
    based upon prices of $2.78 per Mcf of natural gas and $15.76 per barrel of
    oil, compared to $4.47 per Mcf and $23.75 per barrel as of December 31,
    1996.

     The standardized measure of discounted future net cash flows from
production of proved reserves was developed as follows:
 
     1. Estimates are made of quantities of proved reserves and the future
periods during which they are expected to be produced based on year-end economic
conditions.
 
     2. The estimated future gross revenues of proved reserves are priced on the
basis of year-end prices, except in those instances where fixed and determinable
gas price escalations are covered by contracts limited to the price the Company
reasonably expects to receive.
 
     3. The future gross revenue streams are reduced by estimated future costs
to develop and to produce the proved reserves, as well as certain abandonment
costs based on year-end cost estimates and the estimated effect of future income
taxes.
 
     4. Future income taxes are computed by applying the statutory tax rate to
future net cash flows reduced by the tax basis of the properties, the estimated
permanent differences applicable to future oil and gas producing activities, and
tax carry forwards.
 
     The estimates of cash flows and reserves quantities shown above are based
on year-end oil and gas prices. Under Securities and Exchange Commission rules,
companies that follow the full-cost accounting method are required to make
quarterly Ceiling Limitation calculations, using prices in effect as of the
period end date presented (see Note 1). Application of these rules during
periods of relatively low oil and gas prices, even if of short-term seasonal
duration, may result in write-downs.
 
     The standardized measure of discounted future net cash flows is not
intended to present the fair market value of the Company's oil and gas property
reserves. An estimate of fair value would also take into account, among other
things, the recovery of reserves in excess of proved reserves, anticipated
future changes in prices and costs, an allowance for return on investment, and
the risks inherent in reserve estimates.

(1) Amounts prior to the fourth quarter of 1997 have been retroactively restated
    to give recognition to: (a) an equivalent change in capital structure as a
    result of a 10% stock dividend in October 1997 (see Note 2 to the Company's
    financial statements); and (b) the adoption of Statement of Financial
    Accounting Standards No. 128, "Earnings per Share" (see Note 2 to the
    Company's financial statements).

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Swift Energy Company as Managing General Partner:
 
     We have audited the accompanying combined balance sheet of the Partnerships
(See Note 1) (Texas limited partnerships) as of December 31, 1997 and the
related combined statements of income, partners' capital and cash flows for the
year then ended. These combined financial statements are the responsibility of
the Partnerships' Managing General Partner. Our responsibility is to express an
opinion on these combined financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the combined financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall combined
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.
 
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of the Partnerships as
of December 31, 1997, and the results of their operations and their cash flows
for the year then ended in conformity with generally accepted accounting
principles.

           NOTES TO COMBINED FINANCIAL STATEMENTS OF THE PARTNERSHIPS
 
(1) BASIS OF PRESENTATION --
 
     Swift Energy Company ("the Company") has proposed the sale of substantially
all the oil and gas assets of numerous partnerships for which it serves as
Managing General Partner and subsequent liquidation of the Partnerships ("the
Partnerships"). Upon approval of the sale of assets and liquidation, the
Partnerships' assets will consist solely of cash, which each limited partner or
interest holder in the Partnerships (the "Investors") will be entitled to
receive as a distribution. The Company is offering each Investor in the
Partnerships the opportunity to purchase shares of common stock of the Company
with all or part of the cash distribution such Investor will be entitled to
receive.
 
     The accompanying financial statements present in the aggregate the combined
financial position, results of operations, and cash flows of the partnerships
listed below for the year ended December 31, 1997. The combined financial
statements include the Company's general partner and Investor interests. As of
December 31, 1997, the Company's share of partners' capital was $6,707,584.
Certain Partnerships' net profit ownership interests have been reclassified to
the appropriate income statement or balance sheet caption to conform with the
combined financial statement presentation.

   NOTES TO COMBINED FINANCIAL STATEMENTS OF THE PARTNERSHIPS -- (CONTINUED)
 
(2) SIGNIFICANT ACCOUNTING POLICIES --
 
  Use of Estimates --
 
     The preparation of combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the combined financial statements and the reported amounts of
revenues, and expenses during the reporting period. Actual results could differ
from estimates.
 
  Unaudited Interim Information --
 
   
     The unaudited interim combined financial statements as of June 30, 1998 and
for each of the six month periods ended June 30, 1998 and 1997, included herein,
have been prepared pursuant to the rules and regulations of the Securities and
Exchange Commission. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of the Managing General Partner, the
unaudited interim combined financial statements include all adjustments
(consisting only of normal recurring adjustments) necessary to present fairly
the information set forth herein. The interim financial results should not be
regarded as indicative of operating results for an entire year.
    
 
  Investors' Net Income (Loss) Per $100 Investment --
 
   
     The Investors' net income (loss) per $100 investment is based upon the
number of $100 investments into the combined Partnerships' Investor original
capital contributions. The per $100 investment is presented in order to achieve
a comparable measure for all Partnerships, as interests in the Partnerships were
sold on a basis of either $1.00 units, $100 units or $1,000 units.
    
 
  Oil and Gas Properties --
 
     The Partnerships account for their ownership interest in oil and gas
properties using the proportionate consolidation method, whereby the
Partnerships' share of assets, liabilities, revenues, and expenses are included
in the appropriate classification in the combined financial statements.
 
     For financial reporting purposes, the Partnerships follow the "full-cost"
method of accounting for oil and gas property costs. Under this method of
accounting, all productive and nonproductive costs incurred in the acquisition
and development of oil and gas reserves are capitalized. Such costs include
lease acquisitions, geological and geophysical services, drilling, completion,
equipment, and certain general and administrative costs directly associated with
acquisition and development activities. General and administrative costs related
to production and general overhead are expensed as incurred. No general and
administrative costs were capitalized during the year ended December 31, 1997.
 
     Future development, site restoration, dismantlement and abandonment costs,
net of salvage values, are estimated on a property-by-property basis based on
current economic conditions and are amortized to expense as the Partnerships'
capitalized oil and gas property costs are amortized.
 
     The unamortized cost of oil and gas properties is limited to the "ceiling
limitation" (calculated separately for the Partnerships, Investors, and general
partners). The "ceiling limitation" is calculated on a quarterly basis and
represents the estimated future net revenues from proved properties using
current prices, discounted at ten percent. Proceeds from the sale or disposition
of oil and gas properties are treated as a reduction of oil and gas property
costs with no gains or losses being recognized except in significant
transactions.
 
     The Partnerships compute the provision for depreciation, depletion, and
amortization of oil and gas properties on the units-of-production method. Under
this method, the provision is calculated by multiplying the total unamortized
cost of oil and gas properties, including future development, site restoration,
dismantlement and abandonment costs, by an overall amortization rate that is
determined by dividing the physical units
 
                                      F-29
<PAGE>   205
   NOTES TO COMBINED FINANCIAL STATEMENTS OF THE PARTNERSHIPS -- (CONTINUED)
 
of oil and gas produced during the period by the total estimated units of proved
oil and gas reserves at the beginning of the period.
 
     The calculation of the "ceiling limitation" and the provision for
depreciation, depletion, and amortization is based on estimates of proved
reserves. There are numerous uncertainties inherent in estimating quantities of
proved reserves and in projecting the future rates of production, timing, and
plan of development. 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. Accordingly, reserve
estimates are often different from the quantities of oil and gas that are
ultimately recovered.
 
  Cash and Cash Equivalents --
 
     Highly liquid debt instruments with an initial maturity of three months or
less are considered to be cash equivalents.
 
(3) OIL AND GAS CAPITALIZED COSTS --
 
     The following table sets forth capital expenditures related to the
Partnerships' oil and gas operations:

                                                               $3,497,306
                                                               ==========
</TABLE>
 
     All oil and gas property acquisitions are made by the Company on behalf of
the Partnerships. The costs of the properties include the purchase price plus
any costs incurred by the Company in the evaluation and acquisition of
properties.
 
     During 1997, the Partnerships' unamortized oil and gas property costs
exceeded the quarterly calculations of the "ceiling limitations" resulting in an
additional provision for depreciation, depletion, and amortization of
$3,845,484. In addition, the Investors' share of unamortized oil and gas
property costs exceeded their "ceiling limitation" in 1997, resulting in a
valuation allowance of $3,285,133. This amount is included in the income (loss)
attributable to the Investors shown in the statement of partners' capital
together with "combining adjustments" for the differences between the Investors'
valuation allowances and the Partnerships' full cost ceiling write down. The
"combining adjustments" change quarterly as the Partnerships' total
depreciation, depletion, and amortization provision is more or less than the
combined depreciation, depletion, and amortization provision attributable to the
general and Investors.
 
(4) RELATED-PARTY TRANSACTIONS --
 
     During 1997, the Partnerships paid Swift $3,728,043 as general and
administrative overhead allowances, and $204,448 as incentive amounts.
 
(5) FEDERAL INCOME TAXES --
 
     The Partnerships are not tax-paying entities. No provision is made in the
accounts of the Partnerships for federal or state income taxes, since such taxes
are liabilities of the individual partners, and the amounts thereof depend upon
their respective tax situations.
 
     The tax returns and the amount of distributable Partnerships income are
subject to examination by the federal and state taxing authorities. If the
Partnerships' ordinary income for federal income tax purposes is
 
                                      F-30
<PAGE>   206
   NOTES TO COMBINED FINANCIAL STATEMENTS OF THE PARTNERSHIPS -- (CONTINUED)
 
ultimately changed by the taxing authorities, accordingly the tax liability of
the limited partners could be changed. Ordinary income reported on the
Partnerships' federal returns of income for the year ended December 31, 1997,
was $21,651,262. The difference between ordinary income for federal income tax
purposes reported by the Partnerships and net income or loss reported herein
primarily results from the exclusion of depletion (as described below) from
ordinary income reported in the Partnerships' federal returns of income.
 
     For federal income tax purposes, depletion with respect to production of
oil and gas is computed separately by the partners and not by the Partnerships.
Since the amount of depletion on the production of oil and gas is not computed
at the Partnerships level, depletion is not included in the Partnerships' income
for federal income tax purposes but is charged directly to the partners' capital
accounts to the extent of the cost of the leasehold interests, and thus is
treated as a separate item on the partners' Schedule K-1. Depletion for federal
income tax purposes may vary from that computed for financial reporting purposes
in cases where a ceiling adjustment is recorded, as such amount is not
recognized for tax purposes.
 
(6) GAS IMBALANCES --
 
     The Partnerships recognize their ownership interest in natural gas
production as revenue. Actual production quantities sold may be different than
the Partnerships' ownership share in a given period. If the Partnerships' sales
exceed their ownership share of production, the differences are recorded as
deferred revenue. Gas balancing receivables are recorded with the Partnerships'
ownership share of production exceeds sales.
 
(7) VULNERABILITY DUE TO CERTAIN CONCENTRATIONS --
 
     The Partnerships' revenues are primarily the result of sales of their oil
and natural gas production. Market prices of oil and natural gas may fluctuate
and adversely affect operating results.
 
     In the normal course of business, the Partnerships extend credit, primarily
in the form of monthly oil and gas sales receivables, to various companies in
the oil and gas industry which results in a concentration of credit risk. This
concentration of credit risk may be affected by changes in economic or other
conditions and may accordingly impact the Partnerships' overall credit risk.
However, the Managing General Partner believes that the risk is mitigated by the
size, reputation, and nature of the companies to which the Partnerships extend
credit. In addition, the Partnerships generally do not require collateral or
other security to support customer receivables.
 
(8) FAIR VALUE OF FINANCIAL INSTRUMENTS --
 
     The Partnerships' financial instruments consist of cash and cash
equivalents and short-term receivables and payables. The carrying amounts
approximate fair value due to the highly liquid nature of the short-term
instruments.
 
  SUPPLEMENTAL INFORMATION (UNAUDITED)
 
     The following information presents estimates of the Partnerships' proved
oil and gas reserves, which are all located onshore in the United States. All of
the Partnerships' reserves were determined by the Managing General Partner's
personnel and audited by H.J. Gruy and Associates, Inc., independent petroleum
consultants.

     - The Partnerships are not tax-paying entities and accordingly,
       standardized measure of discounted future net cash flows does not include
       future income taxes. Had income taxes been considered, standardized
       measure of discounted future net cash flows for the year ended December
       31, 1997 would have been $85,175,294.
 
     - The Company's general partner and Investor share of pre-tax standardized
       measure of discounted future net cash flows for the year ended December
       31, 1997 was approximately $18,448,873.
 
     The pre-tax standardized measure of discounted future net cash flows from
production of proved reserves was developed as follows:
 
          1. Estimates are made of quantities of proved reserves and the future
     periods during which they are expected to be produced based on year-end
     economic conditions.
 
          2. The estimated future gross revenues of proved reserves are priced
     on the basis of year-end prices, except in those instances where fixed and
     determinable gas price escalations are covered by contracts limited to the
     price the Partnerships reasonably expect to receive.
 
          3. The future gross revenue streams are reduced by estimated future
     costs to develop and to produce the proved reserves, as well as certain
     abandonment costs based on year-end cost estimates and the estimated effect
     of future income taxes.
 
     The estimates of cash flows and reserves quantities shown above are based
on year-end oil and gas prices. The standardized measure of discounted future
net cash flows is not intended to present the fair market value of the
Partnerships' oil and gas property reserves. An estimate of fair value would
also take into account,

                           DIRECT OPERATING EXPENSES
 
1. BASIS OF PRESENTATION
 
   
     On July 2, 1998, Swift Energy Company (the "Company") signed an agreement
dated June 1, 1998 to acquire from Sonat Exploration Company ("Sonat
Exploration"), effective April 1, 1998, certain oil and gas properties located
in the Texas and Louisiana Austin Chalk trend (the "Sonat Properties
Acquisition") for approximately $87.6 million. The acquisition is expected to
close in August 1998.
    
 
   
     The revenues and direct operating expenses associated with the Sonat
Properties Acquisition were derived from Sonat Exploration's accounting records.
Revenues and direct operating expenses, as set forth in the accompanying
historical statements, include oil, gas, and plant product revenues and
associated direct operating expenses related to the net revenue interest (and
acquired royalty interest, as applicable) and net working interest,
respectively, in the acquired properties. Each owner recognizes revenue and
expenses based on its proportionate share of the related production and costs.
The historical statements include oil, gas, and plant product revenues net of
royalties and applicable transportation costs. Expenses include labor, services,
repairs and maintenance, and supplies utilized to operate and maintain the wells
and related equipment as well as severance and ad valorem taxes.
    
 
     The accompanying historical statements vary from an income statement in
that they do not show certain expenses which were incurred in connection with
ownership of the acquired properties including general and administrative
expenses and income taxes. These costs were not separately allocated to the
acquired properties in Sonat Exploration's accounting records and any pro forma
allocation would be both time consuming and expensive and would not be a
reliable estimate of what these costs would actually have been had the acquired
properties been operated historically as a stand alone entity. In addition,
these allocations, if made using historical general and administrative
structures and tax burdens, would not produce allocations that would be
indicative of the historical performance of the acquired properties had they
been assets of the Company due to the greatly varying size, structure,
operations and accounting of the two companies. The accompanying historical
statements also do not include provisions for depreciation, depletion and
amortization as such amounts would not be indicative of those costs which would
be incurred by the Company upon allocation of the purchase price.
 
     For the same reason, primarily the lack of segregated or easily obtainable
reliable data on asset values and related liabilities, a balance sheet is not
presented for the Sonat Properties Acquisition.
 
     At the end of the economic life of these fields, certain restoration and
abandonment costs will be incurred by the respective owners of these fields. No
accrual for these costs is included in direct operating expenses.
 
     With respect to gas sales, the entitlement method is used for recording
revenues. Under this approach, revenues are based on the acquired properties'
proportionate share of the related production.
 
   
     The interim financial data for the six months ended June 30, 1998 and 1997
is unaudited; however, in the opinion of the Company, the interim data includes
all adjustments, consisting only of normal recurring adjustments, necessary for
a fair statement of the results for the interim periods.
    
 
2. RELATED PARTY TRANSACTIONS
 
   
     Affiliates of Sonat Exploration acquired substantially all of the natural
gas production from the acquired properties during each of the three years ended
December 31, 1997. Such sales, attributable to the net revenue interest (and
acquired royalty interest, as applicable) of the acquired properties, amounted
to $20,003,000, $24,483,000 and $17,381,000 for the years ended December 31,
1997, 1996 and 1995, respectively.

3. SUPPLEMENTARY OIL AND GAS INFORMATION (UNAUDITED)
 
  Proved Reserve Estimates
 
     Oil and gas proved reserves cannot be measured exactly. Reserve estimates
are based on many factors related to reservoir performance which require
evaluations by the engineers interpreting the available data, as well as price
and other economic factors. The reliability of these estimates at any point in
time depends on both the quality and quantity of the technical and economic
data, the production performance of the reservoirs, as well as extensive
engineering judgment. Consequently, reserve estimates are subject to revision as
additional data becomes available during the producing life of a reservoir. When
a commercial reservoir is discovered, proved reserves are initially determined
based on limited data from the first well or wells. Subsequent data may better
define the extent of the reservoir and additional production performance, well
tests and engineering studies will likely improve the reliability of the reserve
estimate. The evolution of technology may also result in the application of
improved recovery techniques such as supplemental or enhanced recovery projects,
or both, which have the potential to increase reserves beyond those envisioned
during the early years of a reservoir's producing life.
 
   
     Proved reserves are those quantities which, upon analysis of geological and
engineering data, appear with reasonable certainty to be recoverable in the
future from known oil and gas reservoirs under current prices and costs as of
the date the estimate is made. Proved undeveloped reserves are those reserves
which can be expected to be recovered from new wells on undrilled acreage or
from existing wells where a relatively major expenditure is required. Proved
reserves represent the estimated recoverable volumes after deducting from gross
reserves the portion due land owners or others as royalty or operating
interests.
    
 
   
     Estimates of proved reserves include and rely upon a production and
development strategy. The Company's estimates, as determined by in-house
reservoir engineers, are based upon plans developed using current information
and reflect the Company's risk tolerance with respect to developing proved
undeveloped reserves. Such reserves typically involve a higher degree of
uncertainty. As a result, the Company's estimates may not be comparable to other
oil and gas producers. In any case, many factors such as changes in prices or
costs or errors in sound technical judgment made on the best information
available may cause actual production to vary significantly from estimated
reserves. Estimates of proved reserves for prior periods reflect the Company's
estimate of proved reserves as determined retrospectively using current
information.

  Standardized Measure of Discounted Future Net Cash Flows
 
     The following disclosures concerning the standardized measure of discounted
future cash flows from proved oil and gas reserves are presented in accordance
with the Statement of Financial Accounting Standards No. 69 ("SFAS 69"). As
prescribed by SFAS 69, the amounts shown are based on prices and costs at the
end of each period and a 10 percent annual discount factor. Since prices and
costs do not remain static, and no price or cost changes have been considered,
the results are not necessarily indicative of the fair market value of the
estimated proved reserves, but they do provide a common benchmark which may
enhance the user's ability to project future cash flows.
 
     The standardized measure of discounted future net cash flows related to
proved oil and gas reserves at December 31 was as follows (in thousands):

                                      AND
                          OFFERING OF COMMON STOCK OF
                              SWIFT ENERGY COMPANY



         For the definition of capitalized terms herein which are not otherwise
defined, see "Glossary" in the Joint Proxy Statement/Prospectus.  Other
discussions which are cross-referenced in this Supplement are contained in the
Joint Proxy Statement/Prospectus, unless otherwise noted.

         Swift Energy Company ("Swift" or the "Company") is the Managing
General Partner ("Managing General Partner") of 63 Texas limited partnerships
(the "Partnerships"), including the Partnership, formed between 1986 and 1994
to invest in producing oil and gas properties.  Swift is asking limited
partners (referred to herein as "Investors") in the Partnership (and similarly
in the other 62 Partnerships) to approve a Proposal to ultimately sell all of
the Partnership's oil and gas assets to the Managing General Partner (the
"Proposal") for $373,244, which is a purchase price derived by choosing the
higher of two estimates of fair market value of those assets determined by
three independent Appraisers, and adding to that higher number a 7.5% premium.

         If the Proposal is approved by Investors in the Partnership and its
Companion Partnership, after the ultimate sale of all of its oil and gas assets
the Partnership will dissolve, wind up and terminate.  The Partnership will
receive cash for its oil and gas assets, which in turn is to be distributed to
the Investors in the Partnership (along with the net of all assets less
liabilities of the Partnership) in accordance with their respective percentage
ownership interests in the Partnership.  If Investors in the Partnership
approve the Proposal, then each Investor can elect, in their sole individual
discretion, to receive shares of Common Stock of the Company (without payment
of any brokerage commissions) instead of some or all of the cash which they are
entitled to receive upon the Partnership's liquidation.

   
         The reasons for and effects of the Proposals may be different for
investors in each of the Partnerships.  This Supplement has been prepared to
highlight for the Investors in the Partnership the particular risks, effects
and fairness of the Proposal to the Investors in the Partnership and to provide
information on the Partnership to its Investors, in connection with the
solicitation of proxies by the
    
<PAGE>   216
Managing General Partner for use at the Special Meeting of the Investors in the
Partnership in voting upon the Proposal and to transact such other business as
may be properly presented at the Special Meeting or any adjournments or
postponements thereof.

         BOTH THE VOTE UPON THE PROPOSAL AND ANY ELECTION MADE BY AN INDIVIDUAL
INVESTOR TO RECEIVE SHARES OF SWIFT ENERGY COMPANY COMMON STOCK ARE SUBJECT TO
NUMEROUS RISK FACTORS, INCLUDING THOSE HIGHLIGHTED BELOW.  SEE "RISK FACTORS"
IN THIS SUPPLEMENT AND IN THE JOINT PROXY STATEMENT/PROSPECTUS FOR A FULL
DISCUSSION OF ALL RISK FACTORS.

o        Substantial conflicts of interest exist because if the Proposal is
         approved by the Partnership and its Companion Partnership, the
         Managing General Partner will purchase all of the oil and gas assets
         from the Partnership while it serves as its Managing General Partner.

o        The purchase price for the Partnership's Property Interests may not be
         the highest possible price.

o        No independent representative negotiated the terms of the purchase
         price with the Managing General Partner.

o        No fairness opinion was acquired regarding the fairness of the
         purchase price.

   
o        The Managing General Partner may profit from acquisition of the
         Partnership's oil and gas assets by investing capital in order to
         develop non-producing reserves of the acquired Property Interests and
         possibly through improvement in oil and gas prices.
    

   
o        Estimates of distributions to Investors from continuing operations of
         the Partnership for the life of its reserves are higher than amounts
         anticipated to be received if Investors vote in favor of the Proposal.
         See "Special Factors--Fairness of Proposal of Sale of Assets as
         Compare to Continuing Operations."
    

o        An election by an Investor to receive shares of Swift Common Stock in
         lieu of cash distributable to Investors subjects such Investors to the
         risks of investing in the Company.

                 This Supplement is dated ______________, 1998

                                THE PARTNERSHIP

   
         The Partnership was formed over ten years ago and owns non-operating
Property Interests in producing oil and gas properties in five states in which
its companion partnership, Swift Energy Income Partners 1988-B, Ltd.
("Companion Partnership"), formed at approximately the same time and also
managed by the Managing General Partner, owns the working interests. The
Partnership had expended all of its original capital contributions by the end
of February 1989.  The Partnership's oil and gas properties are principally
natural gas properties, representing approximately 93% of the Partnership's
1997 production and approximately 92% of its total proved reserves at December
31, 1997.    The Companion Partnership has, from time to time, performed
workovers and recompletions on wells in which the Partnership has Property
Interests, using funds advanced by the Managing General Partner or third
parties, to perform these operations, which amounts have been subsequently
repaid.  The Partnership owns interest in 200 wells in 14 fields.
    

   
         The following table presents information on those fields in which the
Partnership has Property Interests which constitute 10% or more of the
Partnership's PV-10 Value at December 31, 1997.  The Partnership's "PV-10
Value" is the estimated future net cash flows (using unescalated prices) from
production of proved reserves attributed to the Partnership's Property
Interests, discounted to present value at 10% per annum.  Attachment D to this
Supplement is the report dated February 10, 1998 of the audit by H.J. Gruy and
Associates, Inc., Independent Petroleum Consultants, of the oil and gas
reserves underlying the Partnership's Property Interests, and future net cash
flow expected from the production of those reserves as of December 31, 1997,
presented both for the Partnership as a whole and as to those reserves solely
attributable to the Investors in the Partnership.  This report has not been
updated to include the effect of production since year-end 1997.  In estimating
these reserves, the Managing General Partner, in accordance with criteria
prescribed by the Securities and Exchange Commission, has used year-end 1997
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.  The Managing General
Partner is not aware of any favorable or adverse event causing a significant
change in the estimated amount (as set forth in Attachment D hereto, which is
the report of H.J. Gruy and Associates, Inc.) of proved reserves of the
properties in which the Partnership owns an interest between December 31, 1997
and the date of this Supplement.
    

   
         The information below includes the location of each field in which the
Partnership has an interest, the number of wells and operators, together with
information on the percentage of the Partnership's total PV-10 Value on
December 31, 1997 attributable to each of these fields.  Information is also
provided regarding the percentage of the Partnership's 1997 production (on a
volumetric basis) from each of these fields.  Of the remaining other fields in
which the Partnership owns a Property Interest, four of such fields each
comprise less than 1% of the Partnership's PV-10 Value at December 31, 1997,
and the PV-10 Value of each of the other six fields averages less than 5% of
the Partnership's PV-10 Value at the same date.

         The Partnership's total assets at year-end 1997 were $480,570 and the
PV-10 Value of its total proved reserves at the same date was $484,518.  Based
upon the audit of the Partnership's Total Proved Reserves at year-end 1997,
those reserves were comprised of the following three categories:

                                                       ===
</TABLE> 

- ----------------
         (1) Proved producing reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.

         (2) Behind-pipe reserves are proved reserves that will not contribute
to cash flows until recompletion projects have been implemented to place them
into production.  The impact of these recompletion projects will also be limited
until the costs of implementation have been recovered.  In general, it is not
appropriate to bring behind-pipe reserves into production until the formation
that is currently producing has been depleted.  Premature recompletions can lead
to permanent reductions in a well's proved reserves.

         (3) Non-developed reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion.  Therefore,
significant additional expenditures are usually required before undeveloped
reserves can be produced.

         Attachment Dis the annual reserves audit and independent reserves
report prepared by H.J. Gruy and Associates, Inc. as to the Partnership's
remaining proved oil and gas reserves available for production over a period in
excess of 15 years.  These quantities have been given a value based upon prices
for oil and gas at December 31, 1997.  The value is determined based upon the
assumption that these prices will remain in effect over the life of these
reserves.  This value is then discounted at 10% per year to arrive at the value
(in today's dollars) of these revenues ("PV-10 Value").  This PV-10 Value for
the Partnership's Property Interests is $484,518.  It is also estimated that
$13,325 in future capital costs must be spent to





                                       4

develop the Partnership's non-producing reserves.  The small amount of these
future development costs reflects the very small percentage of the
Partnership's proved reserves which require drilling to be produced.
    

                                  RISK FACTORS

   
o        Although the fair market value of the Property Interests proposed to
         be purchased from the Partnership by the Managing General Partner was
         based upon a determination by three independent Appraisers, no opinion
         was acquired as to the fairness of the ultimate purchase price, which
         was determined in the Managing General Partner's sole judgment by
         adding a 7.5% premium over the higher of the two fair market value
         estimates for the Partnership's Property Interests determined by the
         Appraisers.  Therefore, the purchase price was not determined on an
         impartial basis by a party not involved in the transaction, and
         another party intent upon purchasing the Property Interests in the
         Partnership might have offered a different purchase price.  There is
         no guarantee that the purchase price represents the highest possible
         price that could be received for the Partnership's Property Interests
         in all circumstances.  It is possible that a higher (or lower) price
         might be received if these assets were sold on another basis, such as
         at auction or in negotiated sales.  Furthermore, the assessment of the
         value of the Partnership's proved non-producing reserves could vary
         widely, given the typical discounting in valuing non-producing
         reserves.
    

o        The Managing General Partner did not retain an independent
         representative to act on behalf of the Investors in the Partnership in
         structuring and negotiating the terms or price of the Proposal or the
         purchase price.  The price at which it is proposed that the Company
         purchase the Property Interests from the Partnership has not been
         negotiated at arm's length and is subject to significant conflicts of
         interest between the Company acting as the purchaser of such
         properties while serving as the Managing General Partner of the
         Partnership.  If an independent representative had been retained for
         the Partnership, the terms or price might have been different and
         possibly more favorable to Investors.

o        The fair market value (excluding the 7.5% premium) established for the
         Partnership's Property Interests is based upon the Appraisers'
         evaluation of that value.  Year-end 1997 prices, along with other
         current market factors, were used as a starting point for the
         Appraisers' analysis, and prices and costs were then escalated at a
         rate of 3.5% per year over 15 years.  Substantial increases in the
         prices for oil and gas in the future might result in Investors
         receiving higher distributions from continued operations of the
         Partnership, although the effect of any higher prices is somewhat
         limited because the Partnership has already produced a substantial
         majority of its oil and gas reserves.

   
o        In order to effectuate the sale of its Property Interests, the
         Proposal must not only be approved by the Partnership, but a similar
         Proposal must be approved by the Companion Partnership.  This
         requirement exists because of the significant lowering of the value of
         either (i) a working interest burdened by a large non- operating
         interest controlled by a different party, or (ii) a non-operating
         interest in properties the operations of which are controlled by a
         third party.  Therefore, even if the Investors in the Partnership
         approve the Proposal to sell their Property Interests, this may not be
         done without the approval of a similar Proposal by investors in the
         Companion Partnership.  If either Partnership does not approve its
         Proposal, then the Managing General Partner will reassess the value of
         the Property Interests of each Partnership and attempt to formulate a
         new proposal for the investors in each such Partnership.

o        Investors that are subject to federal income tax on an investment in
         the Partnership are required to recognize gain or loss on the sale of
         oil and gas assets by the Partnership and the subsequent liquidation
         of the Partnership.  The character of the gain or loss depends on
         certain factors specific to individual Investors.  It is anticipated
         that Investors that acquired their interests in the original offering
         and that are subject to federal income tax will recognize a loss for
         federal income tax purposes.  Any tax that may be due must be paid
         even if such Investors choose to acquire Company Common Stock with
         some or all of their proceeds from property sales.  Investors also
         should consult their individual tax advisors to determine whether they
         are subject to any state tax.  For a broader discussion of the tax
         consequences, Investors should read "Federal Income Tax Consequences
         of Adoption of the Proposals" in the Joint Proxy Statement/Prospectus,
         and "Summary of Federal Income Tax Consequences" in this Supplement.
    

   
o        Investors that are Tax Exempt Plans that have directly or indirectly
         acquired their Partnership interests through debt financing, as
         defined in the Internal Revenue Code of 1986, as amended, may be
         subject to taxation on the Partnership's sale of property and the
         liquidation of the Partnership, while other Tax Exempt Plans are not
         expected to be subject to taxation on the sale and liquidation.  See
         "Federal Income Tax Consequences of Adoption of the Proposal--Tax
         Treatment of Tax Exempt Plans--Debt-Financed Property" in this
         Supplement.  It is anticipated that Tax Exempt Plans that acquired
         their interests in the original offering and that are subject to
         federal income tax will recognize a loss for federal income tax
         purposes.
    

   
o        As currently proposed, Investors that subscribe for Company Common
         Stock pursuant to this Offering may not receive some or all of the
         cash which otherwise would be distributed to them as part of the
         liquidating distribution of their Partnership.  The amount of any cash
         liquidating distribution they actually receive depends upon the
         purchase price to be paid for any Company Common Stock they elect to
         and are entitled to receive pursuant to the terms of this Offering.
         For federal income tax purposes, Investors subscribing for shares of
         Company Common Stock will be treated as though they had purchased
         those shares for cash, even though they never had actual possession of
         the cash used to acquire the shares.  Additionally, the fact that such
         Investors elect to acquire Company Common Stock rather than receive
         cash in liquidation of their Partnership interests will not affect the
         federal income tax consequences attending the liquidation of their
         Partnership interests.  Because the purchase of shares of Company
         Common Stock will reduce the cash received by Investors upon the
         Partnership's liquidation, to the extent that Investors owe federal
         income tax as a result of the liquidation, they may not receive
         sufficient cash to pay some or all of any tax they may owe on the
         liquidation.  Such Investors owing tax as a result of the liquidation
         will have to pay such tax from sources other than any cash liquidating
         distribution from the Partnership.

                             CONFLICTS OF INTEREST

   
         There are substantial conflicts of interest which exist by virtue of
the Managing General Partner acting in that capacity on behalf of the
Partnership while at the same time acting as the proposed purchaser of all of
the oil and gas assets of the Partnership.  These conflicts of interest are
discussed below.
    

o        The terms of the Proposal are established by the Company which is also
         the Managing General Partner of the Partnership.

o        Neither the Managing General Partner nor a majority of its independent
         directors retained an independent representative to act on behalf of
         the Partnership's Investors for the purposes of negotiating the terms
         upon which any such sale to the Managing General Partner would be made
         or for the preparation of a report concerning the fairness of the
         entire transaction.

See "Summary--Conflicts of Interest" and "Conflicts of Interests" in the Joint
Proxy Statement/Prospectus.

                                SPECIAL FACTORS

BACKGROUND AND PURPOSE OF THE PROPOSAL

   
         [VARIABLE PARA. BY P'SHIP TYPE] A number of factors have led to the
decision of the Company in its capacity as Managing  General Partner to solicit
approval of the Proposal by Investors in the Partnership.  As contemplated when
the Partnership was organized, and given the expenditure of virtually all of
the Partnership's capital to purchase producing properties over nine years ago,
the production from Partnership oil and gas assets declined over time.  It was
always anticipated that a time would arrive when the Managing General Partner
would propose that the business of the Partnership be concluded, its assets
sold or otherwise disposed of and the Partnership liquidated and dissolved.
The general improvement in the prices for natural gas over the last several
years, relative to such prices in the mid-1990's, make this an appropriate
time, especially in light of the age of the Partnership and the high percentage
of its reserves comprised of natural gas, to consider the Proposal to sell the
Partnership's Property Interests.  The structure being proposed, which involves
the sale of the Partnership's oil and gas assets to the Managing General
Partner, is being submitted for approval by Investors in an attempt to realize
the highest value for those assets.  For the reasons set out below, the
Managing General Partner believes that the Proposal is fair to Investors in the
Partnership, given that the purchase price for these assets has been determined
by taking the higher of two fair market value estimates by three independent
Appraisers and adding to it a 7.5% premium.
    

         Approval of the Proposal will have the following effects:

   
1.       The Managing General Partner will purchase all of the oil and gas
         assets of the Partnership, provided its Companion Partnership has
         approved its proposal.
    

   
2.       When the Partnership sells all of its oil and gas assets, it will be
         required to liquidate and distribute its remaining assets (principally
         the cash proceeds from the sale) to its partners (including the
         general partners) in accordance with their respective ownership
         interests in the Partnership.
    





                                       7
<PAGE>   222
3.       Investors will be given the option of electing to receive shares of
         Swift Common Stock, in amounts that they choose on an individual
         basis, in lieu of some or all of the cash they would be entitled to
         receive upon the Partnership's liquidation.

   
4.       Investors in the Partnership may be taxed on the sale of the
         Partnership's oil and gas assets, although such sale is expected to
         result in a taxable loss to Investors that acquired their interests in
         the original offering.
    

   
PROPOSED PURCHASE PRICE
    

   
         As discussed in greater detail below, the Petroleum Engineering
Consultants estimated that the aggregate fair market value of the Partnership's
Property Interests as of December 31, 1997 is $342,030.  CIBC Oppenheimer
estimated a fair market value of the same Property Interests at the same date
of $347,204.  The Special Transactions Committee chose the higher of these two
determinations as the "Fair Market Value" for the purchase of these interests
and the Board of Directors of the Company determined to pay a 7.5% premium
($26,040) above the Fair Market Value to purchase the Partnership's Property
Interests, resulting in a purchase price of $373,244.  This compares to the
total purchase price for all of the oil and gas assets of all 63 Partnerships
which are considering similar proposals of approximately $81 million.  The
valuation estimates of the Appraisers are attached to this Supplement and
incorporated herein by reference as follows:  Attachment A is the fair market
value estimate of H.J. Gruy and Associates, Inc., Attachment B is the fair
market value estimate of J.R. Butler and Company, and Attachment C is the fair
market value estimate of CIBC Oppenheimer Corp.  The PV-10 Value prepared on an
annual basis by H.J. Gruy of the same Property Interests as of the same date is
$484,518.
    

REASONS FOR THE PROPOSAL

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

   
         Current Liquidating Distribution Lowers Volatility Risk.  The
Partnership has been in existence for over ten years.  The Managing General
Partner believes that the ability to receive the estimated liquidating
distribution in one lump sum at this time, rather than in smaller amounts over
a longer period, is one of the benefits of the Proposal, without the risk of
such distributions being negatively affected by oil and gas price decreases and
the inherent risks associated with geological, engineering and operational
matters.  It is also the Managing General Partner's belief that improvements
over the last several years in the level of gas prices, relative to such prices
in the mid-1990's, makes 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 future prices and market volatility
cannot be predicted with any accuracy.
    

   
         Decreasing Cash Flow While Expenses Continue.  As of December 31,
1997, approximately  83% of the Partnership's ultimate recoverable reserves had
been produced.  As a result of such 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.  The
Partnership's underlying interests in oil and gas reserves are expected to
continue to decline as remaining reserves are produced.  Declines in well
production are based principally upon the maturity of the wells, not on market
factors.  These declines will continue to occur while oil field overhead and
operating costs ($9,090 in 1997) and direct and
    





                                       8
<PAGE>   223
general and administrative expenses ($34,649 in 1997) continue, which are
relatively fixed amounts.  Each producing well requires a certain amount of
operating and other costs, which 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.  By
accelerating the liquidation of the Partnership, those future administrative
costs will be avoided by the Partnership.

         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 particularly gas prices that occurred subsequent to the
purchase of the Partnership's Property Interests.  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 1997 year-end reserve
calculations, the Partnership had only about 17% of its ultimate recoverable
reserves 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 material positive impact on the
total return on investment to Investors in view of the expenses of the
Partnership as described above.  Approximately 93% of the Partnership's 1997
production and approximately 92% of its total proved reserves at year-end 1997
were comprised of natural gas. As of the summer of 1998, oil prices are
significantly lower than those for natural gas.  Historically when there has
been significant difference between the price of gas and oil, those prices have
adjusted to become reasonably equivalent.  Consequently, there may be a benefit
in selling the Partnership's Property Interests at this time and avoiding any
future decreases in prices of natural gas, although the direction and severity
of adjustments in prices for gas and/or oil are impossible to predict.

   
         Behind-Pipe Reserves.  It is estimated that approximately 33% of the
remaining reserves attributable to properties in which the Partnership has an
interest are behind-pipe reserves, which are unlikely to be producible for many
years because behind-pipe reserves always require completion of a well in a
different producing zone which does not take place until production is depleted
from the currently producing zones.  Recovery in amounts great enough to
significantly impact the results of the Partnership's operations and the
ultimate cash distributions to partners can only occur with the investment of
new capital.  As provided in its Partnership Agreement, the Partnership
expended all of the Investors' net commitments for the acquisition of Property
Interests many years ago and it no longer has capital to invest.  No additional
development activities are contemplated by the Companion Partnership on the
properties in which the Partnership has an interest.
    

   
         Limited Partners' Tax Reporting.  Each Investor will continue to have
an 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
Investors generally are unable to dispose of their Units.  See "Partnership
Business and Financial Condition--No Trading Market" in this Supplement.
Following the sale of the Partnership's Property Interests and dissolution of
the Partnership, Investors will realize gain or loss, or a combination of both,
under federal income tax laws.  See "Summary of Federal Income Tax
Consequences--Taxable Gain or Loss upon Sale of Properties" herein.
Thereafter, Investors will have no further tax reporting obligations with
respect to the Partnership.  The dissolution of the Partnership will also allow
Investors to take a capital loss deduction for syndication costs incurred in
connection with formation of the Partnership.   See "Summary of Federal Income
Tax Consequences--Liquidation of the Partnership" in this Supplement.

COLLECTIVE ANALYSIS OF PURCHASE PRICE; PREMIUM OVER FAIR MARKET VALUE

         The Special Transactions Committee selected H.J. Gruy and Associates,
Inc. ("H.J. Gruy" or "Gruy"), J.R. Butler and Company ("J.R. Butler" or
"Butler"), which are both petroleum engineering consultants, and CIBC
Oppenheimer Corp.  ("CIBC Oppenheimer"), an investment banking firm, to
estimate the fair market value of the Property Interests of each of the
Partnerships.  Collectively, H.J. Gruy, J.R. Butler and CIBC Oppenheimer are
referred to herein as the "Appraisers," and H.J. Gruy and J.R. Butler together
are sometimes referred to herein as the "Petroleum Engineering Consultants."

         The following subsections of the "Special Factors" section of the
Joint Proxy Statement/Prospectus should be reviewed for information concerning
the selection and qualification of the Appraisers and the parameters of the
valuation estimates: "Independent Appraisal of the Fair Market Value of
Property Interests of the Partnerships," "Qualification of Appraisers," and
"Fair Market Value."

   
         The Petroleum Engineering Consultants arrived at a fair market
valuation estimate of the Partnership's Property Interests based upon appraisal
of the projected discounted cash flow from its various Property Interests.  On
the other hand, the investment banking firm of CIBC Oppenheimer made a
valuation estimate of the Partnership's Property Interests based upon the
application of multiple quantitative and qualitative factors.  The quantitative
factors include, among other things, a review of relevant valuation criteria
from comparable acquisitions of both oil and gas properties and companies that
are predominantly active in the oil and gas industry, and a review of valuation
criteria for relevant publicly traded oil and gas companies.
    

         The process used by the Petroleum Engineering Consultants in preparing
their valuation estimate is discussed at length in the Joint Proxy
Statement/Prospectus under "Special Factors--Valuation by Petroleum Engineering
Consultants." As described therein, the Petroleum Engineering Consultants
individually audited the estimate of present value of future net cash flows
from the 44 property groups in which Property Interests are owned by the
Partnerships to whom similar proposals are being made to sell all of their oil
and gas assets and liquidate their Partnerships.  The Partnership owns Property
Interests in four of these property groups.  The Petroleum Engineering
Consultants began their analysis based upon the year-end 1997 PV-10 Value of
each property audited by H.J. Gruy and together they re-evaluated reserve
quantities, projected operating costs and cash flows.  The present value of
this reserves analysis was then derived by escalating year-end 1997 prices
($2.38 per MMBtu and $16.00 per barrel before adjustments for Btu content for
gas and gravity variances for oil as well as transportation charges and
geographic location) and costs by 3.5% per year for 15 years.  This present
value was then adjusted for various individual field risks and risk adjustments
of proved non-producing reserves and proved undeveloped reserves.  The result
of this collective analysis by the Petroleum Consulting Engineers was their
estimation that the fair market value of Property Interests owned by the
Partnership was $342,030 as of December 31, 1997.

         The methodology used by CIBC Oppenheimer to prepare its valuation
estimate is discussed at length under "Special Factors--Valuation by CIBC
Oppenheimer" in the Joint Proxy Statement/Prospectus.  CIBC Oppenheimer's
evaluation of the Partnership's Property Interests began with





                                       10
<PAGE>   225
   
the PV-10 Value of each property group, as calculated by Swift and audited by
H.J. Gruy, which Gruy report dated February 10, 1998 is Attachment D to this
Supplement.  CIBC Oppenheimer then divided the property groups into two
categories.  Those property groups with reserves consisting primarily of proved
developed producing reserves were placed in the "Conventional Case" category.
Those property groups with significant proved developed non-producing or
undeveloped reserves were placed in the "Non-Conventional Case" category.
[NEXT IS VARIABLE SENTENCE:]  The Partnership has interests in property groups
which were in both the "Conventional Case" and the "Non-Conventional Case"
categories.  CIBC Oppenheimer then valued each property group (including those
groups in both the "Conventional Case" and "Non- Conventional Case" categories)
by applying the multiples discussed under "Special Factors--Valuation by CIBC
Oppenheimer--Valuation Multiples" in the Joint Proxy Statement/Prospectus to
each property group's PV-10 Value, proved reserves on a BOE basis, and
projected 1998 EBIDTA.  A separate set of multiples was used for property
groups in the Conventional Case category and the Non-Conventional Case
category, respectively.  This provided CIBC Oppenheimer with three estimated
values for each property group.  The average of these three values yielded CIBC
Oppenheimer's estimation of the fair market value of each property group.  CIBC
Oppenheimer then allocated the appropriate portion of each property group's
estimated fair market value to the Partnership based upon the Partnership's
Property Interests in each property group.  The result of this analysis by CIBC
Oppenheimer was an estimation that the fair market value of the Partnership's
Property Interests was $347,204 on December 31, 1997.
    

   
         The Special Transactions Committee has determined that, in keeping
with the definition of Fair Market Value, the higher of these two estimations
of fair market value, or $347,204, represents the Fair Market Value of the
Partnership's Property Interests.  Accordingly, the fair market value
estimation of the Petroleum Consulting Engineers and the fair market value
determined by CIBC Oppenheimer were compared to each other and the higher of
the two was chosen as the Fair Market Value of the Property Interests owned by
the Partnership.  The variation between the fair market value estimate of the
Partnership's Property Interests prepared by the Petroleum Consulting
Engineers, on one hand, and CIBC Oppenheimer on the other was 1.0%.
    

DETERMINATION OF PREMIUM OVER FAIR MARKET VALUE BY THE COMPANY

   
         The Special Transactions Committee presented its recommendation to the
Board of Directors of the Company as to the Fair Market Value of the Property
Interests of the Partnership.  The Board of Directors of the Company then
determined that paying a 7.5% premium over the Fair Market Value of the
Partnership's Property Interests was appropriate and fair based upon the
factors and for the reasons discussed below.  Because the Company has served as
Managing General Partner of the Partnership for over ten years, it is
intimately familiar with the Property Interests owned by the Partnership.  The
Managing General Partner believes that if the Property Interests were to be
sold to a third party purchaser that was not equally familiar with those
interests, it is likely that the purchaser would discount the purchase price to
account for that lack of familiarity and associated risks.  If these interests
are purchased by the Company, then the additional cost and personnel often
inherent in making a property acquisition are not required, because the files
and deed records already exist in the Company's lease and computer systems, and
conveyance and title issues do not exist.
    

         In the judgment of the Company, the purchase of the Partnership's
Property Interests together with interests in many of the same properties owned
by other Partnerships at approximately the same time will result in
efficiencies to the Company in aggregating such interests.  Swift's long-term
knowledge of the risks involved in these properties means that it is in a
better position to evaluate these risks than third parties.





                                       11
<PAGE>   226
         Based upon the Company's experience in purchasing properties, the lack
of additional costs often incurred in purchasing oil and gas properties in
which the purchaser has owned no interest, and the Company's intimate
familiarity with these Property Interests and consequent ability to evaluate
acquisition risks, it was deemed appropriate to pay a premium representing the
benefit to the Company arising from these factors.

   
         The amount of the premium principally was based upon management's
experience in purchasing properties which contain both producing reserves and
drilling potential, without any statistical or analytical study prepared by the
Company in the course of determining the amount of this premium.  Since 1979,
the Company, on behalf of itself and others, has gained a wide range of
experience with the valuation of oil and gas properties and the prices for
their purchase and sale, having purchased $478 million of such properties in
129 separate transactions.  Other purchasers might have determined it
inappropriate to pay  a premium, or if so, to pay a premium based upon other
factors or in a different amount.  Because there has been no independent third
party involved in the decision to pay this premium or in the determination of
its amount, and no fairness opinion has been requested regarding this premium,
conflicts of interest exist in its determination, although the Managing General
Partner believes, based upon its knowledge of the oil and gas industry, its
knowledge of the properties involved, its experience in purchasing and selling
oil and gas properties, and the benefits from purchasing the Property Interests
which are particular to the Company, that the amount being offered to the
Partnership to purchase its Property Interests is fair.
    

"SPECIAL FACTORS" SECTION IN THE JOINT PROXY STATEMENT/PROSPECTUS

   
         The Special Factors section in the Joint Proxy Statement/Prospectus
contains a full discussion of the determination of the purchase price proposed
to be paid by the Managing General Partner to purchase the Partnership's
Property Interests.  In addition to those topics discussed at length in this
Supplement, the Joint Proxy Statement/Prospectus addresses alternative
transactions that were considered but not proposed for the Partnership and the
other 62 partnerships to whom similar proposals are being made simultaneously.
It also contains information regarding the prior relationships between the
Appraisers, the Partnerships and the Managing General Partner, the absence of a
request that an independent representative negotiate the terms of the purchase
of the Partnership's Property Interests by the Managing General Partner, the
manner in which expenses are to be borne for the transaction, the Managing
General Partner's source of funds to purchase the Partnership's Property
Interests, and the benefits that the Managing General Partner would receive
from purchasing such Property Interests.
    

ESTIMATES OF LIQUIDATING NET CASH DISTRIBUTION AMOUNT IF THE PROPOSAL IS
APPROVED

   
         The purchase price proposed to be paid to the Partnership for its oil
and gas assets is the Fair Market Value plus the purchase premium.  As is the
case with all oil and gas properties purchases, the purchase is proposed to be
made as of the date which the properties were evaluated (in this case December
31, 1997). A portion of the reserves used to establish the Fair Market Value
has been produced during 1998.  Most of the net revenue received by the
Partnership from the sale of such production since the proposed purchase date
(December 31, 1997) has been distributed to the partners during 1998 through
quarterly cash distributions or, to the extent not already distributed, will be
distributed as part of the Partnership's liquidating distributions.
Accordingly, the actual purchase price which will be paid to the Partnership
will be reduced by the amount of net production revenue received by the
Partnership after December 31, 1997.

         Set forth in the table below are estimated net proceeds that the
Partnership may realize from the sale of the Partnership's Property Interests,

         General Partner.

   
(8)      Under the terms of the offer of Swift Common Stock to Eligible
         Purchasers, if the Investors in the Partnership approve the Proposal
         and its Companion Partnership approves a similar Proposal, such
         Investors will be Eligible Purchasers.  The minimum number of shares
         which can be purchased by an Eligible Purchaser is a round lot of 100
         shares.  Based upon estimated net cash distribution of $6.92 per $100
         Unit, the number of Units shown above is the minimum number of Units
         which it will be necessary for an Investor to own in order to purchase
         a minimum 100 share round lot of Swift Common Stock without providing
         any additional funds from other sources.  This calculation is based
         upon an assumed purchase price of Swift Common Stock of $18.00 per
         share (which is the same price upon which the proforma financial
         statements contained in the Joint Proxy Statement/Prospectus are
         based) for an aggregate purchase price for 100 shares of Swift Common
         Stock of $1,800.  The minimum number of Units shown is subject to
         change, based upon the price for Swift Common Stock at a future date
         as specified under "Offering of Shares of Swift Energy Company Common
         Stock if Investors Approve the Proposal--Offer of Swift Common
         Stock--Purchase Price" in this Supplement.  However, if an Eligible
         Purchaser has interests in more than one Partnership, the cash
         distributions he will be entitled to receive may be aggregated to meet
         the minimum share purchase requirement of a round lot of 100 shares.
    

ESTIMATES OF NET CASH DISTRIBUTIONS AVAILABLE FROM CONTINUED OPERATIONS

   
         If the Partnership were to retain its Property Interests until they
have reached their economic limit, the table below estimates the return to
Investors, without regard to amounts distributable to the General Partners,
discounted to present value, based upon 1997 year-end pricing without
escalation and upon the discount assumptions used above.  The estimates of the
present value of future net cash distributions have been further reduced by
estimates of 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.
The following estimated future net revenues do not take into account any
additional costs which might be incurred by the Partnership's Companion
Partnership due to needed future maintenance or remedial work on the properties
in which the Partnership has an interest, which would reduce such net revenues.

         change in the selling prices of oil or gas.  For further discussion of
         this, see "Special Factors--Reasons for the Proposal" in this
         Supplement.  The actual prices that will be received and the

will depend on results of operations until liquidation of the Partnership,
final costs and other contingencies and circumstances.

FAIRNESS OF PROPOSED SALE OF ASSETS TO THE MANAGING GENERAL PARTNER
   AS COMPARED TO CONTINUING OPERATIONS
    

   
         Based on the above tables, it is estimated that an Investor could
expect to receive $6.92 per $100 Unit upon the sale of the Partnership's
Property Interests as of September 30, 1998.  In comparison, it is estimated
that an Investor could expect to receive $7.83 per $100 Unit, discounted to
present value at 10% per annum ($14.53 per $100 Unit on an undiscounted basis)
if the Partnership continued operations.  The Managing General Partner believes
that the Proposal to sell the Partnership's Property Interest as compared to
continuing operations is fair to Investors for the reasons discussed below.
    

   
         Although the estimates contained in the two tables above show that
estimated net cash distributions to Investors (based on net present value) from
continued operations would be approximately 13% higher than estimated net cash
distributions from selling the Partnership's Property Interests and liquidating
the Partnership currently, the Managing General Partner believes there is a
substantial advantage in receiving the liquidating net cash distribution in one
lump sum at this time. The estimates of net cash distributions from continued
operations are based upon 1997 year-end pricing.  It is highly likely that
over such a long period of time, oil and gas prices will vary often and
possibly widely, as has been demonstrated historically, from the prices used to
prepare these estimates.  Continued operations over such a long period of time
subject Investors to the risk of receiving lower levels of net cash
distributions if oil and gas prices over this period are lower on average than
those used in preparing the estimates of net cash distributions from continued
operations.  Continued operations also subject Investors' potential net cash
distributions 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.  The Managing General Partner also believes that there
is an advantage to Investors taking any funds to be received upon liquidation
and redeploying those assets in other investments, rather than continuing to
receive decreasing levels of net cash distributions over such a long period of
time.
    

   
         Because there is no active trading market for Units in the
Partnership, the only other comparable value for Units is the 1997 "Unit
Value," which, as explained below, is the amount calculated on an annual basis
under the terms of the limited partnership agreement at which the Managing
General Partner can offer to repurchase Units from Investors.  As of January 1,
1997, this "Unit Value" was $10.66 per $100 Unit.  In 1997, the Investors
received net cash distributions of $1.50 per $100 Unit, and are estimated to
receive another $1.48 per $100 Unit before September 30, 1998, which converts
to a comparable value of $7.68 per $100 Unit before any adjustments to
quantities of reserves or oil and gas prices during this almost two year
period.  Under the terms set out in the limited partnership agreement, each
year the Managing General Partner is required to furnish to Investors the Unit
Value, and Investors have the right to present their Units for purchase by the
Managing General Partner for the Unit Value.  The Unit Value amount is
determined on an entirely different basis than the estimates of fair market
value by the Appraisers.  Furthermore, the Unit Value was calculated over one
year ago, with a valuation date of January 1, 1997, as opposed to the date for
assessment of Fair Market Value being December 31, 1997. Because of significant
changes in oil and gas prices within a year's time, in addition to the changes
in reserve quantities during that period, the calculation of Unit Value as of
January 1, 1997, and the Fair Market Value as of December 31, 1997, are not
comparable.  Unit Value is derived by taking 70% of the present value of proved
oil and gas reserves (discounted at 10% per annum) calculated on an escalated
pricing basis, plus cash and accounts receivable less outstanding debts and
obligations of the Partnership.
    





                                       16
<PAGE>   231
         Although the PV-10 Value of the Partnership's Property Interests is
higher than the purchase price proposed if the Proposal is approved, the
Managing General Partner does not believe that the PV-10 Value accurately
reflects the amount that oil and gas industry members are currently paying to
purchase producing properties on the open market.

FAIRNESS OF PROPOSED SALE

   
         The Managing General Partner believes that the entire transaction
related to the Proposal involving the proposed method of sale of the
Partnership's Property Interests is fair to Investors for the following
reasons, without giving any particular weight to any reason:
    

   
         1.      The Managing General Partner believes that the most important
                 element of the Proposal is the determination of the Fair
                 Market Value of the Partnership's Property Interests.  The
                 price to be paid by the Company to purchase the Partnership's
                 Property Interests was determined in the Managing General
                 Partner's sole judgment by adding a 7.5% premium to the higher
                 of the two estimates by the Appraisers of the fair market
                 value of the Partnership's Property Interests.  Two of the
                 three Appraisers are qualified independent petroleum
                 engineering firms and the other is an investment banking firm.
                 The factors and methods used by the Appraisers in determining
                 Fair Market Value are discussed in detail under "Special
                 Factors--Independent Appraisal of the Fair Market Value of
                 Property Interests of the Partnership," "--Fair Market Value,"
                 "--Valuation by Petroleum Engineering Consultants,"
                 "--Valuation by CIBC Oppenheimer" and "--Collective Analysis
                 of Purchase Price" in the Joint Proxy Statement/Prospectus.
    

   
         2.      No transaction will take place unless the Proposal is approved
                 by Investors holding at least a majority of the interests in
                 such Partnership (without any vote by the Managing General
                 Partner) and a similar Proposal is approved by the
                 Partnership's Companion Partnership.
    

         3.      The Special Transactions Committee made the determination as
                 to the retention of the Appraisers and approved the fair
                 market value estimates provided by the Appraisers and
                 recommended the reports of the Appraisers to the Board of
                 Directors of the Company.  The Special Transactions Committee
                 is comprised solely of independent directors of the Company.

   
         4.      If the Proposals are approved by investors in any of the 63
                 Partnerships considering similar proposals, it is likely that
                 the Managing General Partner will expend the capital necessary
                 to develop non- producing reserves on the Property Interests
                 purchased by the Managing General Partner from those
                 Partnerships.  If all of the Property Interests which are the
                 subject of the Proposals are acquired by the Company, such
                 Property Interests in the aggregate will constitute less than
                 20% of the Company's total assets.  Because the Managing
                 General Partner would be the beneficiary of any such increase
                 in value, the Managing General Partner is hereby offering to
                 Eligible Purchasers the opportunity to purchase up to
                 2,500,000 shares of Common Stock of the Company.  There is no
                 requirement that any purchase of Swift's Common Stock be made.
                 See "Offer of Swift Common Stock" below.
    





                                       17
<PAGE>   232
   
         5.      In structuring the Proposal and related transactions, the
                 Managing General Partner considered that any sale of
                 Partnership Property Interests, whether to the Managing
                 General Partner or to a third party, would be a taxable
                 transaction.  Thus, if an Investor subject to federal income
                 tax chooses to use the proceeds received on liquidation of
                 that Investor's Partnership to purchase Swift Common Stock,
                 tax will still have to be paid on any taxable income resulting
                 from the Partnership's sale of oil and gas assets, without
                 regard to whether the Investor has cash proceeds remaining
                 from his liquidating distribution to pay such tax.  Investors
                 that purchased their interests in the original offering,
                 however, are not expected to recognize gain on the sale.
    
   
    
   
         The determination by the Special Transactions Committee to pay the
purchase premium, the independent Appraisers' determination of the fair market
value of the properties and the payment of a 7.5% premium do not necessarily
remove the substantial conflicts of interest which exist in the transaction
between the Managing General Partner's serving in that capacity on behalf of
the Partnership and also acting as the purchaser of the Property Interests from
the Partnership.  No fairness opinion was requested or received regarding the
ultimate purchase price to be paid by the Managing General Partner to purchase
the Partnership's oil and gas assets.  The Managing General Partner determined
that rather than setting the purchase price for Partnership Property Interests
itself, it would be preferable to instead request three different independent
Appraisers to determine two sets of fair market values at which such Property
Interests should be purchased, and then to choose the higher of those two
values.  The Managing General Partner believes that when the Appraisers
rendered their opinions as to the "fair market value" of the Partnership's
Property Interests, inherent within their appraisal opinions were the
Appraisers' determination that these "fair market values" were "fair," or such
determinations would not have been made.  Consequently, no independent fairness
opinion was requested regarding "fair market values" or upon the premium.  The
Managing General Partner believes that adding a 7.5% premium to the highest of
the two fair market value determinations made by the three Appraisers only
serves to increase the amount to be paid to Investors upon liquidation of the
Partnership and does not require a separate fairness opinion.  The
determination by a third party purchaser as to the purchase price might be more
or less than that being proposed by the Managing General Partner as a purchase
price for these Property Interests.
    

   
         The determination to submit the Proposal to Investors in which the
Company would purchase the Property Interests of the Partnership was deemed by
the Managing General Partner to be the most appropriate time and method for
liquidation of the Partnership.  This decision was made in light of full
consideration by the Managing General Partner of its fiduciary obligations to
Investors.  Furthermore, the decision to use three Appraisers, rather than one,
and to have the Appraisers actually set the fair market value for purchase of
the Property Interests, rather than the Managing General Partner setting that
value and requesting a fairness opinion, were based upon the Managing General
Partner's consideration of the substantial conflicts of interest which exist in
the transactions covered hereby.
    

See "Special Factors--Fairness of Proposed Sale" in the Joint Proxy
Statement/Prospectus.

MANAGING GENERAL PARTNER BENEFITS

   
         Benefits accruing to the Company resulting from the purchase of the
Partnerships' Property Interests include the following:  the Managing General
Partner will share the benefits available to Investors through liquidating its
Partnership interests (including both its general partner interests and any
Units it owns) and receiving the same value of those interests as Investors.
Additionally, the Company intends to
    





                                       18
<PAGE>   233
   
profit from purchasing the Partnership's Property Interests through a return on
capital used to purchase those oil and gas assets and invest in their
development.  By purchasing the Partnership's Property Interests itself, the
Managing General Partner will be able to maintain its position as operator of
certain properties in which the Partnership owns an interest.  Consequently,
the Managing General Partner would continue to receive operating fees as
operator of those properties.  The sale of the Partnership's Property Interests
to the Managing General Partner will have no effect or an inconsequential
effect on the Managing General Partner's net book value and net earnings.
However, the purchase of all of the oil and gas assets of the Partnerships
would increase the Company's proved reserves, cash flow and total assets by a
significant amount.  Lastly, if individual Investors which approve the Proposal
elect to purchase Company Common Stock, rather than receiving cash upon
liquidation of the Partnership, the Company will benefit by using stock to pay
the purchase price, rather than using its available cash resources or borrowing
facilities.
    

See "Special Factors--Managing General Partner Benefits" in the Joint Proxy
Statement/Prospectus.

SIMULTANEOUS PROPOSALS TO COMPANION PARTNERSHIPS

   
         Simultaneous Proposals are being made to investors in the
Partnership's Companion Partnership.  If both the Partnership and its Companion
Partnership do not approve their respective Proposals, it is likely to affect
the ability of the Partnership to consummate the sale of its Property
Interests.  Although the Investors in the Partnership may desire to sell their
Property Interests, the separation of the working interest and the
non-operating interests in the same properties may affect the salability of
those interests on a permanent basis.   If, for example, the Partnership
approves the Proposal but the Companion Partnership does not, the value of a
non-operating interest is likely to be negatively affected by the lack of
control over operations.  [VARIABLE REVERSAL:  If, for example, the Partnership
approves the Proposal but the Companion Partnership does not, the value of a
working interest burdened by a large non- operating interest is likely to be
lowered significantly.]  If the Partnership's Companion Partnership does not
approve its Proposal, then the Managing General Partner will advise the
Investors in the Partnership.  If the Investors in the Partnership's Companion
Partnership do not vote in favor of its Proposal, then it is likely that the
Partnership will continue  operations and will produce its reserves until
depletion, with steadily decreasing rates of cash flow, and consequently
steadily decreasing amounts of cash distributions to the Investors.
    

                             VOTING ON THE PROPOSAL

   
         The Joint Proxy Statement/Prospectus and the Form of Proxy enclosed
with this Supplement are being provided for use at the Special Meeting of
Investors of the Partnership and at any adjournment or postponement of such
meeting (the "Meeting") to be held at 16825 Northchase Drive, Houston, Texas at
4:00 p.m. Central Time on ______, ___________, 1998.  The Meeting is being
called for the purpose of considering and voting upon the Proposal to
ultimately sell all of the oil and gas assets of the Partnership to the
Company, and to dissolve, wind up and terminate the Partnership and to transact
such other business as may be properly presented at the Meeting, all in
accordance with the terms and provisions of the Partnership's limited
partnership agreement (the "Partnership Agreement"), and the Texas Revised
Limited Partnership Act (the "Texas Act").  This Joint Proxy
Statement/Prospectus and enclosed Form of Proxy are first being mailed to
Investors on or about _____________, 1998.
    

   
         Pursuant to the terms of the Partnership Agreement, the Partnership, 
if not terminated earlier, will continue in being through January 1, 2021, at
which point it will terminate automatically.

<PAGE>   234
   
         Under the Partnership Agreement, the Proposal must be approved by the
affirmative vote of Investors holding 51% or more of the Units in the
Partnership as of the Record Date (defined below).  Therefore, an abstention by
an Investor will have the same effect as a vote against the Proposal.  The
solicitations are being made for votes in favor of the Proposal (which will
result in liquidation and dissolution of the Partnership).  As of the Record
Date, 45,181 Units were outstanding and held by record holders (excluding the
Units held by the Managing General Partner as discussed below).  Accordingly,
the affirmative vote of holders of at least 23,042 Units is required to approve
the Proposal.  Each Investor appearing on the records of the Partnership as of
______, 1998 (the "Record Date") is entitled to notice of the Meeting and is
entitled to one vote for each Unit held by such Investor.  VJM Corporation, a
California corporation, is the Special General Partner of the Partnership, and
owns a 1.0% interest in the Partnership as a general partner, but owns no
Units.  The Managing General Partner owns a general partner interest in the
Partnership of 9.0%.  Additionally, the Managing General Partner owns 2,523
outstanding Units in the Partnership, which ownership results from the Managing
General Partner's purchase over the life of the Partnership of Units from
Investors under the right of presentment, contained in the Partnership
Agreement.  Under the Partnership Agreement, the Managing General Partner may
not vote any Units owned by it for matters such as the Proposal.  The Managing
General Partner's non-vote, in contrast to abstention by Investors, will not
affect the outcome, because for purposes of adopting the Proposal, its Units
are excluded from the total number of voting Units.
    

VOTE REQUIRED

         The actual proxy to be used to register the vote on the Proposal
before you is the separate green sheet of paper included with this Supplement
and Joint Proxy Statement/Prospectus.  PLEASE USE THE GREEN PROXY TO CAST YOUR
VOTE ON THE PROPOSAL.

   
         If a proxy is properly signed and is not revoked by an Investor, the
Units it represents will be voted in accordance with the instructions of the
Investor.  If no specific instructions are given, the Units [VARIABLE: SDIS]
will be voted FOR the Proposal.  An Investor may revoke his proxy at any time
before it is voted at the Meeting.  Any Investor who attends the Meeting and
wishes to vote in person may revoke his proxy at that time.  Otherwise, an
Investor 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.
    

SOLICITATION

   
         The solicitation is being made by the Partnership.  The Partnership
will bear the costs of the preparation of the Joint Proxy Statement/Prospectus
and of the solicitation of proxies and such costs will be allocated 90% to the
Investors and 10% to the general partners pursuant to the terms of the
Partnership Agreement.  As the Managing General Partner holds approximately
5.26% [VARIABLE PERCENTAGES] of the Units held by all Investors, 5.26% of the
costs borne by the Investors will be borne by the Managing General Partner, in
addition to the portion of the Partnership's total costs borne by the general
partners by virtue of their interest in the Partnership as general partners.
Solicitations will be made primarily by mail.  In addition, a number of regular
or temporary 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 Investors to encourage the return of proxies, although it
does not anticipate doing so.

                  PARTNERSHIP BUSINESS AND FINANCIAL CONDITION

   
         The Partnership is a Texas limited partnership formed June 2, 1988.
Units in the Partnership are registered under Section 12(g) of the Securities
Exchange Act of 1934. The Partnership owns non-operating interests in producing
oil and gas properties within the continental United States in which the
Companion Partnership also managed by the Managing General Partner owns the
working interests.  By the end of February 1989, the Partnership had expended
all of its original capital contributions for the purchase of Property
Interests in oil and gas producing properties.  During 1997, approximately 91%
of the Partnership's revenue was attributable to natural gas production.  From
time to time, the Companion Partnership has performed workovers and
recompletions of wells in which the Partnership has non-operating interests,
using funds advanced by the Managing General Partner or third parties to
perform these operations, which amounts have been subsequently repaid.  For
information about the business of the Partnership, see the attached Annual
Report on Form 10-K for the year ended December 31, 1997 and Quarterly Report
on Form 10-Q for the quarter ended June 30, 1998.
    

   
         Investors made contributions of $4,770,363 in the aggregate to the
Partnership, the net proceeds of which have all been invested.  The Managing
General Partner has made capital contributions with respect to its general
partner interest of $38,125.  Additionally, pursuant to the right of
presentment set forth in the Partnership Agreement, it has purchased 2,523
Units from Investors.  From inception through July 31, 1998, the Partnership
has made net cash distributions to its Investors totaling $2,772,700.  Details
of the amounts of cash distributions made to partners over the past three years
and nine months are set out under "Cash Distributions" below.  Through July 31,
1998, the Managing General Partner has received net cash distributions from the
Partnership of $257,787 with respect to its general partner interest, and
$18,515 related to its limited partner interest.  On a per Unit basis,
Investors had received, as of July 31, 1998, $58.12 per $100 Unit, or
approximately 58.1% 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.  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 $15.37 per
barrel of oil and $1.80 per Mcf of natural gas.  The majority of the
Partnership's Property Interests were acquired by the end of February 1989 and
were comprised principally of natural gas reserves.  At that time current
prices were predicted to escalate according to certain parameters from then
current levels to approximately $29.37 per barrel of oil and $3.43 per Mcf of
natural gas during 1997.  The predicted price increases did not occur, and
prices fell precipitously from 1990 to 1991.  Most of the Partnership's
reserves were produced from 1989 to 1993, during which time the oil prices
received by the Partnership for its production in fact averaged $18.79 per
barrel, but the prices for the Partnership's principal asset, natural gas,
averaged approximately $1.67 per Mcf.  A comparison of gas prices as described
in this paragraph appears in the graph presented below.
    

   
         The following graphs illustrate the effect on Partnership performance
of the variance between gas prices projected at the time of acquisition of the
Partnership's Property Interests and actual gas prices received for production
(as illustrated in the second graph) during the Partnership's existence.
Information is presented as to gas prices only due to the fact that a
substantial majority of the Partnership's production has been natural gas.

<PAGE>   237
         Lower prices also have 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.

CASH DISTRIBUTIONS

   
         Cash distributions are made to the partners in the Partnership on a
quarterly basis.  During the past three years and the first nine months of
1998, aggregate cash distributions made to all partners in the Partnership
(including the Managing General Partner) and the cash distributions per Unit
made to the Investors were:

TRANSACTIONS BETWEEN THE MANAGING GENERAL PARTNER AND THE PARTNERSHIP

   
         Under the Partnership Agreement, the Managing General Partner has
received certain compensation for its services and reimbursement for
expenditures made on behalf of the Partnership, which was paid at closing of
the offering of interests in the Partnership, in addition to revenues
distributable to the Managing General Partner with respect to its general
partner interest or with respect to Units it has purchased under the Investors'
right of presentment.  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
                 $119,259, internal acquisition costs reimbursements of
                 $155,605 and formation costs reimbursements of $95,407 from
                 the Partnership from inception through December 31, 1997, none
                 of which has been received during the two years ended December
                 31, 1997.

   
         o       In the past, the Managing General Partner has received
                 operating fees for wells in which the Partnership has Property
                 Interests and for which the Managing General Partner or its
                 affiliates serve as operator.  During the years ended December
                 31, 1997 and December 31, 1996 the aggregate operating fees
                 paid to the Company as operator by the Partnership were $1,920
                 and $7,136, respectively.  Monthly operating fees ranged from
                 $100 to $125 per well on an 8/8th's basis (i.e., the total
                 amount of operating fees paid by all interest owners in the
                 well).  The Managing General Partner no longer serves as
                 operator of any properties in which the Partnership owns an
                 interest and, consequently, no longer receives per-well
                 operating fees.
    





                                       23
<PAGE>   238
         o       The Managing General Partner is entitled to be reimbursed 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
                 Investors' original capital contributions to the Partnership
                 relative to investor contributions to all public partnerships
                 formed to purchase interests in producing properties for which
                 the Managing General Partner serves in that capacity.  Through
                 December 31, 1997, the Managing General Partner had received
                 $312,053 in the general and administrative overhead allowance
                 from the Partnership, of which $16,058 and $15,140 have been
                 reimbursed during the years ended December 31, 1997 and
                 December 31, 1996, respectively.
   
    

         o       The Managing General Partner has been reimbursed $25,064 in
                 direct expenses by the Partnership, all of which was billed
                 by, and then paid directly to, third party vendors, of which
                 $1,744 and $2,368 have been reimbursed during the years ended
                 December 31, 1997 and December 31, 1996, respectively.

NO TRADING MARKET

   
         There is no trading market for the Units, and none is expected to
develop, as described above under "Special Factors--Fairness of Proposed Sale
of Assets to the Managing General Partner as Compared to Continuing
Operations." Under the Partnership Agreement, Investors 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 the Partnership
Agreement.  Originally 426 Investors invested in the Partnership.  As of
__________, 1998, there were 411 Investors (excluding the Managing General
Partner).  The number of Units in the Partnership issued and outstanding at
that date was 47,703.63.  Through December 31, 1997, the Managing General
Partner had purchased 2,523 Units from Investors pursuant to the right of
presentment.  The Managing General Partner does not have an obligation to
repurchase Investor interests pursuant to this right of presentment, but merely
an option to do so when such interests are presented for repurchase.
    

PRINCIPAL HOLDERS OF INVESTOR UNITS

         The Managing General Partner holds 5.26% of all outstanding Units of
the Partnership, resulting from the purchase of Units from Investors under
their right of presentment.  To the knowledge of the Managing General Partner,
there are two other holders of Units that hold more than 5% of the Units, each
representing approximately 5.2% of the total Units outstanding.

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.

   
    
                   SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES

GENERAL

   
         The following briefly summarizes the federal income tax consequences
set forth under "Federal Income Tax Consequences of Adoption of the Proposals"
in the Joint Proxy Statement/Prospectus.  Statements of legal conclusions
herein regarding tax consequences are based upon an opinion of Hoops & Levy,
L.L.P., Special Tax Counsel, 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 reported judicial decisions and published
positions of the Internal Revenue Service (the "Service"),  private letter
rulings dated October 6, 1987 and August 22, 1991 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 Investors.
    

   
         A MORE COMPLETE SUMMARY OF THE FEDERAL INCOME TAX CONSEQUENCES TO
INVESTORS MAY BE FOUND IN THE REGISTRATION STATEMENT IN "FEDERAL INCOME TAX
CONSEQUENCES OF ADOPTION OF THE PROPOSALS."  THIS SUMMARY DOES NOT DESCRIBE ALL
THE TAX ASPECTS WHICH MAY AFFECT INVESTORS NOR IS IT A COMPLETE DESCRIPTION OF
THE TAX ASPECTS IT DOES DESCRIBE.  It is generally directed to Tax Exempt Plans
that are Investors who are the original purchasers of the Units and hold
interests in the Partnership as "capital assets" (generally, property held for
investment).  Each Investor that is a corporation, trust, estate, or other
partnership 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

         Tax Exempt Plans are subject to tax on their unrelated business
taxable income ("UBTI").  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 net profits interest, as structured under the net profits
agreement, 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 Investors that are Tax





                                       25
<PAGE>   240
Exempt Plans either taxable gain or loss for federal income tax purposes, even
though there may be gain or loss upon the sale of the Property Interest for
federal income tax purposes.

         DEBT-FINANCED PROPERTY

         Debt-financed property is property held to produce income that is
subject to acquisition indebtedness.  The income is taxable in the same
proportion which the debt bears to the total cost of acquiring the property.
Generally, acquisition indebtedness is the unpaid amount of (i) indebtedness
incurred by a Tax Exempt Plan to acquire an interest in a partnership, (ii)
indebtedness incurred in acquiring or improving property, or (iii) indebtedness
incurred either before or after the acquisition or improvement of property or
the acquisition of a partnership interest if such indebtedness would not have
been incurred but for such acquisition or improvement, and if incurred
subsequent to such acquisition or improvement, the incurrence of such
indebtedness was reasonably foreseeable at the time of such acquisition or
improvement.

         If an Investor 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.  If a Tax Exempt Plan has not caused its
Partnership Interest to be debt-financed property, and based upon
representations of the Managing General, the Property Interest is not expected
to be considered debt-financed property.

   
TAX TREATMENT OF INVESTORS SUBJECT TO FEDERAL INCOME TAX DUE TO DEBT-FINANCING
    

         All references hereinbelow to Investors refers solely to Investors
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.

         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 an Investor's income, gain,
loss and deduction from the Partnership is subject to federal taxation.

         TAXABLE GAIN OR LOSS UPON SALE OF PROPERTIES

   
         Investors will realize and recognize gain or loss, or a combination of
both, upon the Partnership's sale of its properties prior to liquidation.  It
is projected, however, that Investors will realize a net taxable loss upon the
sale of the Partnership properties.
    





                                       26
<PAGE>   241
         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 an Investor in liquidation is less than such Investor's adjusted
tax basis in his Partnership interest, the Investor will realize and recognize
a capital loss to the extent of the excess.  If the amount of cash distributed
is greater than such Investor's adjusted tax basis in his Partnership interest,
the Investor will recognize a capital gain to the extent of the excess.
Because each Investor 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 Investors will be less than
such Investors' bases in their Partnership interests and thus will generate
capital losses.

         CAPITAL GAIN TAX

   
         Net long-term capital gains of individuals, trusts and estates
generally will be taxed at a maximum rate of 20%, while ordinary income,
including income from the recapture of intangible drilling and development
costs, depreciation and depletion, will be taxed at a maximum rate depending on
that Investor's taxable income of 36% or 39.6%.
    

         PASSIVE LOSS LIMITATIONS

         Investors 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.

         An Investor'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.  An
Investor's share of any gain or loss realized upon the sale of the net profits
interest is expected to be characterized as portfolio income or loss and may
not offset, or be offset by, passive activity gains or losses.

Gentlemen:

At your request, we have audited the proved, probable and possible reserves and
future net cash flow as of December 31, 1997, prepared by Swift Energy Company
("Swift") for certain interests owned by the partners in Swift Energy Managed
Pension Assets 1988-A, Ltd. This audit has been conducted according to the
Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserve
Information approved by the Board of Directors of the Society of Petroleum
Engineers on October 30, 1979. We have reviewed these properties and where we
disagreed with the Swift reserve estimates, Swift revised its estimates to be in
agreement.

From this audit, and in consultation with J.R. Butler and Company, our estimate
of the fair market value of this partnership is $342,030.

Fair market value as used herein is defined as that price that a willing buyer
will pay and a willing seller will accept at a given point in time, with neither
the buyer nor the seller under any compulsion to buy or sell, and both having
reasonable knowledge of all the material circumstances.

To estimate the fair market value attributable to the proved developed producing
reserves, the 10 percent discounted future net cash flow was multiplied by a
suitable factor (less than one) to account for the risk associated with the
reserves, operating expenses, and prices and to approximate tax consequences.
The internal rate of return and payout time were computed for this quantity and
compared with those at which current acquisitions are completed. Suitable
adjustments are then made to correspond to these two financial indices. Proved
developed nonproducing, proved undeveloped, probable and possible reserves
require capital investments and must be treated appropriately. For these cases,
the capital is added to the discounted net cash flow, then multiplied by a
suitable risk factor and the capital then subtracted. This has the effect that
capital is spent with certainty and the operating cash income is burdened with
the risk. Internal rate of return and payout time is calculated for each
estimate to establish reasonableness based upon the risk associated with the
reserve category.

Swift Energy Company                  -2-                         April 17, 1998


The estimated future net cash flow is that cash flow which will be realized from
the sale of the estimated net reserves after deduction of royalties, ad valorem
and production taxes, direct operating costs and capital expenditures, when
applicable. Surface and well equipment salvage values and well plugging and
field abandonment costs have not been considered in the cash flow projections.
Future net cash flow as stated in this report is before the deduction of federal
income tax.

The following parameters are incorporated in the economic projections referenced
in this report. Initial oil prices are the existing prices on December 31, 1997,
and are escalated 3.5 percent per year beginning in 1999 through the year 2012
after adjusting for transportation and gravity variances. Initial natural gas
prices are those existing on December 31, 1997, and are escalated 3.5 percent
per year beginning in 1999 through the year 2012 after adjusting for
transportation and Btu content. Operating expenses are escalated at an annual
rate of 3.5 percent until the year 2012. The actual prices that will be received
and the associated costs may be more or less than those projected.

For those wells with sufficient production history, reserve estimates and rate
projections are based on the extrapolation of established performance trends.
Reserves for other producing and nonproducing properties have been estimated
from volumetric calculations and analogy with the performance of comparable
wells. The reserves referenced in this study are estimates only and should not
be construed as exact quantities. Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available. The proved reserves are
estimated in accordance with the definitions included in the Securities and
Exchange Commission Regulation S-X, Rule 4-10(a) except for the price and cost
escalations. The definitions are included in part as Attachment I. The probable
and possible reserves conform to the definitions approved by the Society of
Petroleum Engineers, Inc. The definitions are included as Attachment II.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented. The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December. Interim production to December 31, 1997, has been
estimated. Operating expenses as supplied by Swift were not audited, but were
reviewed for reasonableness. No independent well tests, property inspections or
audits of operating expenses were conducted by our staff in conjunction with
this study. We did not verify or determine the extent, character, obligations,
status or liabilities, if any, arising from any current or possible future
environmental liabilities that might be applicable.

In order to audit the reserves, costs and future cash flows referenced in this
report, we have relied in part on geological, engineering and economic data
furnished by our client. Although we have made a best efforts attempt to acquire
all pertinent data and to analyze it carefully with methods accepted by the
petroleum industry, there is no guarantee that the volumes of oil or gas or the
cash flows projected will be realized. The reserve and cash flow projections
referenced in this report may require revision as additional data become
available.

H.J. Gruy and Associates, Inc. is unrelated to Swift and has no interest in the
properties included in this report. In particular:

         1. We do not own a financial interest in Swift or its oil and gas 
            properties.

         2. Our fee is not contingent on the outcome of our work or report.

         3. We have not performed other services for or have any other 
            relationship with Swift that would affect our independence.

         4. No instructions were given and no limitations were imposed by Swift 
            on the scope or methodology to be used by us in preparing such
            estimates; we did not accept or incorporate any assumptions from
            Swift, but merely called upon Swift to the extent customary in the 
            oil and gas industry to gather and provide certain background
            information which we determined to be relevant and appropriate; we
            determined what information to use; and how and to what extent such
            information should be relied upon, in estimating the fair market
            values shown above.

If investments or business decisions are to be made in reliance on these
estimates by anyone other than our client, such person with the approval of our
client is invited to visit our offices at his expense so that he can evaluate
the assumptions made and the completeness and extent of the data available on
which our estimates are based.

Any distribution or publication of this report or any part thereof must include
this letter in its entirety.

                                              Yours very truly,

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                         PETROLEUM RESERVES DEFINITIONS
   SOCIETY OF PETROLEUM ENGINEERS (SPE) AND WORLD PETROLEUM CONGRESS (WPC)(1)

Reserves are those quantities of petroleum which are anticipated to be
commercially recovered from known accumulations from a given date forward. All
reserve estimates involve some degree of uncertainty. The uncertainty depends
chiefly on the amount of reliable geologic and engineering data available at the
time of the estimate and the interpretation of these data. The relative degree
of uncertainty may be conveyed by placing reserves into one of two principal
classifications, either proved or unproved. Unproved reserves are less certain
to be recovered than proved reserves and may be further sub-classified as
probable and possible reserves to denote progressively increasing uncertainty in
their recoverability.

The intent of the SPE and WPC in approving additional classifications beyond
proved reserves is to facilitate consistency among professionals using such
terms. In presenting these definitions, neither organization is recommending
public disclosure of reserves classified as unproved. Public disclosure of the
quantities classified as unproved reserves is left to the discretion of the
countries or companies involved.

Estimation of reserves is done under conditions of uncertainty. The method of
estimation is called deterministic if a single best estimate of reserves is made
based on known geological, engineering and economic data. The method of
estimation is called probabilistic when the known geological, engineering, and
economic data are used to generate a range of estimates and their associated
probabilities. Identifying reserves as proved, probable, and possible has been
the most frequent classification method and gives an indication of the
probability of recovery. Because of potential differences in uncertainty,
caution should be exercised when aggregating reserves of different
classifications.

Reserves estimates will generally be revised as additional geologic or
engineering data become available or as economic conditions change. Reserves do
not include quantities of petroleum being held in inventory, and may be reduced
for usage of processing losses if required for financial reporting.

Reserves may be attributed to either natural energy or improved recovery
methods. Improved recovery methods include all methods for supplementing natural
energy or altering natural forces in the reservoir to increase ultimate
recovery. Examples of such methods are pressure maintenance, cycling,
waterflooding, thermal methods, chemical flooding, and the use of miscible and
immiscible displacement fluids. Other improved recovery methods may be developed
in the future as petroleum technology continues to evolve.

PROVED RESERVES

Proved reserves are those quantities of petroleum which, by analysis of
geological and engineering data, can be estimated with reasonable certainty to
be commercially recoverable, from a given date forward, from known reservoirs
and under current economic conditions, operating methods, and government
regulations. Proved reserves can be categorized as developed or undeveloped.

If deterministic methods are used, the term reasonable certainty is intended to
express a high degree of confidence that the quantities will be recovered. If
probabilistic methods are used, there should be at least a 90% probability that
the quantities actually recovered will equal or exceed the estimate.

Establishment of current economic conditions should include relevant historical
petroleum prices and associated costs and may involve an averaging period that
is consistent with the purpose of the reserve estimate, appropriate contract
obligations, corporate procedures, and government regulations involved in
reporting these reserves.

In general, reserves are considered proved if the commercial producibility of
the reservoir is supported by actual production or formation tests. In this
context, the term proved refers to the actual quantities of petroleum reserves
and not just the productivity of the well or reservoir. In certain cases,
proved reserves may be assigned on the basis of well logs and/or core analysis
that indicate the subject reservoir is hydrocarbon bearing and is analogous to
reservoirs in the same area that are producing or have demonstrated the ability
to produce on formation tests.

The area of the reservoir considered as proved includes (1) the area delineated
by drilling and defined by fluid contacts, if any, and (2) the undrilled
portions of the reservoir that can reasonably be judged as commercially
productive on the basis of available geological and engineering data. In the
absence of data on fluid contacts, the lowest known occurrence of hydrocarbons
controls the proved limit unless otherwise indicated by definitive geological,
engineering or performance data.

<PAGE>   251

Reserves may be classified as proved if facilities to process and transport
those reserves to market are operational at the time of the estimate or there is
a reasonable expectation that such facilities will be installed. Reserves in
undeveloped locations may be classified as proved undeveloped provided (1) the
locations are direct offsets to wells that have indicated commercial production
in the objective formation, (2) it is reasonably certain such locations are
within the known proved productive limits of the objective formation, (3) the
locations conform to existing well spacing regulations where applicable, and (4)
it is reasonably certain the locations will be developed. Reserves from other
locations are categorized as proved undeveloped only where interpretations of
geological and engineering data from wells indicate with reasonable certainty
that the objective formation is laterally continuous and contains commercially
recoverable petroleum at locations beyond direct offsets.

Reserve which are to be produced through the application of established improved
recovery methods are included in the proved classification when (1) successful
testing by a pilot project or favorable response of an installed program in the
same or an analogous reservoir with similar rock and fluid properties provides
support for the analysis on which the project was based, and, (2) it is
reasonably certain that project will proceed. Reserves to be recovered by
improved recovery methods that have yet to be established through commercially
successful applications are included in the proved classification only (1) after
a favorable production response from the subject reservoir from either (a) a
representative pilot or (b) an installed program where the response provides
support for the analysis on which the project is based and (2) it is reasonably
certain the project will proceed.

UNPROVED RESERVES

Unproved reserves are based on geologic and/or engineering data similar to that
used in estimates of proved reserves; but technical, contractual, economic, or
regulatory uncertainties preclude such reserves being classified as proved.
Unproved reserves may be further classified as probable reserves and possible
reserves.

Unproved reserves may be estimated assuming future economic conditions different
from those prevailing at the time of the estimate. The effect of possible future
improvements in economic conditions and technological developments can be
expressed by allocating appropriate quantities of reserves to the probable and
possible classifications.

PROBABLE RESERVES

Probable reserves are those unproved reserves which analysis of geological and
engineering data suggests are more likely than not to be recoverable. In this
context, when probabilistic methods are used, there should be a least a 50%
probability that the quantities actually recovered will equal or exceed the sum
of estimated proved plus probable reserves.

In general, probable reserves may include (1) reserves anticipated to be proved
by normal step-out drilling where subsurface control is inadequate to classify
these reserves as proved, (2) reserves in formations that appear to be
productive based on well log characteristics but lack core data or definitive
tests and which are not analogous to producing or proved reservoirs in the area,
(3) incremental reserves attributable to infill drilling that could have been
classified as proved if closer statutory spacing had been approved at the time
of the estimate, (4) reserves attributable to improved recovery methods that
have been established by repeated commercially successful applications when (a)
a project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir characteristics appear favorable for commercial application, (5)
reserves in an area of the formation that appears to be separated from the
proved area by faulting and the geologic interpretation indicates the subject
area is structurally higher than the proved area, (6) reserves attributable to a
future workover, treatment, re-treatment, change of equipment, or other
mechanical procedures, where such procedure has not been proved successful in
wells which exhibit similar behavior in analogous reservoirs, and (7) 
incremental reserves in proved reservoirs where an alternative interpretation of
performance or volumetric data indicates more reserves than can be classified as
proved.

POSSIBLE RESERVES

Possible reserves are those unproved reserves which analysis of geological and
engineering data suggests are less likely to be recoverable than probable
reserves. In this context, when probabilistic methods are used, there should be
a least a 10% probability that the quantities actually recovered will equal or
exceed the sum of estimated proved plus probable plus possible reserves.

In general, possible reserves may include (1) reserves which, based on
geological interpretations, could possibly exist beyond areas classified as
probable, (2) reserves in formations that appear to be petroleum bearing based
on log and core analysis but may not be productive at commercial rates, (3)
incremental reserves attributed to infill drilling that are subject to technical
uncertainty, (4) reserves attributed to improved recovery methods when (a) a
project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir

<PAGE>   252

characteristics are such that a reasonable doubt exists that the project will be
commercial, and (5) reserves in an area of the formation that appears to be
separated from the proved area by faulting and geological interpretation
indicates the subject area is structurally lower than the proved area.

RESERVE STATUS CATEGORIES

Reserve status categories define the development and producing status of wells
and reservoirs.

     DEVELOPED: Developed reserves are expected to be recovered from existing
     wells including reserves behind pipe. Improved recovery reserves are
     considered developed only after the necessary equipment has been installed,
     or when the costs to do so are relatively minor. Developed reserves may be
     sub-categorized as producing or non-producing.

         PRODUCING: Reserves subcategorized as producing are expected to be
         recovered from completion intervals which are open and producing at the
         time of the estimate. Improved recovery reserves are considered
         producing only after the improved recovery project is in operation.

         NON-PRODUCING. Reserves subcategorized as non-producing include shut-in
         and behind-pipe reserves. Shut-in reserves are expected to be recovered
         from (1) completion intervals which are open at the time of the
         estimate but which have not started producing, (2) wells which were
         shut-in for market conditions or pipeline connections (3) wells not
         capable of production for mechanical reasons. Behind-pipe reserves are
         expected to be recovered from zones in existing wells, which will
         require additional completion work or future recompletion prior to the
         start of production.

     UNDEVELOPED RESERVES: Undeveloped reserves are expected to be recovered:
     (1) from new wells on undrilled acreage, (2) from deepening existing wells
     to a different reservoir, or (3) where a relatively large expenditure is
     required to (a) recomplete an existing well or (b) install production or
     transportation facilities for primary or improved recovery projects.

                                            AS OF DECEMBER 31, 1997

                                            1988-A, LTD.


ATTENTION:       SPECIAL TRANSACTIONS COMMITTEE
                 SWIFT ENERGY COMPANY BOARD OF DIRECTORS

At the request of SWIFT ENERGY COMPANY (SWIFT), J. R. BUTLER AND COMPANY
(JRBCO) has conducted an evaluation audit of the hydrocarbon reserves and
future net cash flow as of December 31, 1997, associated with 44 Acquisition
Programs located in the U.S.A.  From this audit, and in consultation with H. J.
Gruy and Associates, Inc. (Gruy), JRBCO has generated its opinion of a "fair
market value" for these properties.  The market values of the properties were
distributed to various partnerships based on ownership to determine the fair
market value of each partnership.  In JRBCO'S opinion, utilizing the
distribution of properties into the proper partnerships, the estimated market
value of SWIFT ENERGY MANAGED PENSION ASSETS 1988-A, LTD. is $342,030.

Proved reserves in this instance are defined as those estimated volumes of
crude oil, condensate, natural gas, and natural gas liquids that geological and
engineering data demonstrate with reasonable certainty to be commercially
recoverable in the future from known reservoirs under a reasonable price and
cost escalation scenario.  Probable reserves are the estimated quantities of
commercially recoverable hydrocarbons associated with known accumulations which
are based on engineering and geological data similar to those used in the
estimates of proved reserves but, for various reasons, these data lack the
certainty required to classify the reserves as proved.  Possible reserves are
the estimated quantities of commercially recoverable hydrocarbons associated
with known accumulations, which are based on engineering and geological data
which are less complete and less conclusive than the data used in estimates of
probable reserves.  In some cases, economic or regulatory uncertainties may
dictate a probable or possible classification.

Recovery of proved reserves is not without risk but, as generally considered in
the industry, the risk of recovering probable reserves is substantially greater
than that associated with proved categories.  Likewise, possible reserves are
less certain to be recovered than probable.

The reserves and future performance estimates were prepared utilizing standard
petroleum engineering methods.  For properties with sufficient production
history,





                                       1
<PAGE>   254
reserves estimates and rate projections were based primarily on extrapolation
of established performance trends and reconciled, whenever possible, with
volumetric and/or material balance calculations.  For the non-producing zones
and undeveloped locations, reserves were determined by a combination of
volumetric calculations and analogy.  Volumetrically determined reserves or
those determined by analogy are generally subject to greater qualifications
than reserves estimates supported by established production decline curves
and/or material balance calculations.  Determination and classification of
proved reserves were performed (with exception of the use of escalated prices
and costs) in accordance with Securities and Exchange Commission guidelines.
The definitions used also conform to those promulgated by the Society of
Petroleum Engineers (SPE) and the World Petroleum Congresses (WPC).

The reserves and resulting "value estimates" included  in this study are not
exact quantities.  Future conditions may affect the recovery of estimated
reserves, revenue and net cash flow, and all categories of reserves may be
subject to revision and/or reclassification as more performance and well data
become available.  Please note, the reserves estimates made by JRBCO were done
in conjuction with an evaluation audit and are not the result of in-depth field
studies.  In conducting this audit JRBCO reviewed approximately 65% of SWIFT'S
proved "PV 10  value" (SEC PV10 as of December 31, 1997) for the total 44
Acquisition Programs.

Basic evaluation data were obtained principally from SWIFT and public sources.
The production data available to JRBCO were generally through  August 1997.
Gas and liquid prices were year end (CY 1997) prices as used in SWIFT'S
December 31, 1997, SEC cash flow runs.

Estimates of drilling, completion and workover costs were based on information
supplied by SWIFT.  Operating costs were also based on data supplied by SWIFT
in their Lease Operating Statement which was reviewed by JRBCO.  Surface and
well equipment salvage values and well plugging and field abandonment costs
were not considered in the revenue projections.

The estimates of future net cash flow used in market value calculations are
those revenues which should be realized from the sale of the estimated reserves
after deduction of royalties, ad valorem and production taxes, direct operating
costs and required capital expenditures, when applicable.  Future net cash flow
as used in this evaluation is before the deduction of federal income tax.

Market value estimates were obtained by applying qualitative risk adjustments
considered appropriate for the various reserves categories and "profit factors"
(as applicable) against discounted future net cash flow values obtained from an
escalated cost and pricing scenario.  Prices, costs and investments were
escalated at 3.5%/year for 15 years.  Final market value estimates were derived
in conjunction and consultation with Gruy.

In the conduct of our review, we have not independently verified the accuracy
and completeness of information and data furnished by SWIFT with respect to
ownership interests, oil and gas production volumes and rates, historical costs
of operation and development, product prices, agreements relating to current
and future operations and sales of production and other information relative to
such things as timing or scheduling of drilling or recompletion operations.

Field inspections were not made in connection with the preparation of this
report.  Furthermore, no judgments were made relative to environmental or other
legal liabilities.

It should be recognized that any oil or gas reserves estimate or forecast of
production and income is a function of engineering and geological
interpretation and judgment.  Such estimates should, therefore, be accepted and
used with the understanding that technical data, economic criteria or
regulatory information obtained subsequent to a study may justify revisions
which could increase or decrease the original estimates of reserves and value.

Neither JRBCO, nor any of its personnel, have any direct or indirect interest
in SWIFT or its affiliates.  JRBCO is an independent consulting firm as
provided in the Standards Pertaining to the Estimating and Auditing of Oil and
Gas Reserves Information promulgated by the Society of Petroleum Engineers.

JRBCO'S compensation is not contingent upon the results of its reserves
estimates, cash flow analyses or "market value opinion" which result from its
review of the subject properties.

Houston, TX  77060

Attention:        Special Transactions Committee
                  Swift Energy Company Board of Directors

Gentlemen:

Pursuant to that certain letter agreement dated February 27, 1998 (the
"Agreement") between the Special Transactions Committee (the "Committee") of the
Board of Directors of Swift Energy Company ("Swift" or the "Company") and CIBC
Oppenheimer Corp. ("CIBC Oppenheimer"), you have retained CIBC Oppenheimer to
prepare an independent financial analysis as to the estimated fair market value
(the "CIBC Oppenheimer Valuation") of various interests (the "Assets") in oil
and gas properties (the "Properties'), which Assets are owned by Swift Energy
Managed Pension Assets 1988-A Ltd. (the "Partnership") of which the Company is
the managing general partner ("General Partner"). CIBC Oppenheimer performed a
similar analysis for 62 other partnerships (the "Partnerships") of which the
Company is the General Partner. It is CIBC Oppenheimer's understanding that the
General Partner has proposed to purchase substantially all of the Partnership's
Assets and, in turn, dissolve and wind up the Partnership. It is also CIBC
Oppenheimer's understanding that the Committee has also retained the reserve
engineering firms of H.J. Gruy & Associates, Inc. and J.R. Butler & Company
(collectively, the "Engineering Consultants") to prepare a separate analysis as
to the estimated fair market value of the Assets (the "Engineering Consultants'
Valuation").

In arriving at the CIBC Oppenheimer Valuation, we, among other things:

          (i)     Reviewed the historical financial returns to the limited 
                  partners of the Partnership;

          (ii)    Held discussions with senior management of the Company as to
                  the Partnership's operational and financial prospects;


<PAGE>   257

          (iii)   Held discussions with senior management of the Company
                  regarding the general characteristics of the Properties
                  underlying the Assets, including location, productive
                  geological formations, future development potential and oil
                  and gas marketing arrangements;

          (iv)    Held discussions with the Engineering Consultants regarding
                  the general characteristics of the Properties underlying the
                  Assets, including location, productive geological formations
                  and future development potential;

          (v)     Reviewed the reserve engineering reports supplied to us by the
                  Engineering Consultants and, particularly, reviewed the
                  estimated future net cash flow to be generated from the
                  production of proved reserves of the Properties underlying the
                  Assets discounted to present value using an annual discount
                  rate of 10% (the "PV-10 Value") dated as of December 31, 1997;
                  these amounts were 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 future
                  income tax expense or depreciation, depletion and
                  amortization;

          (vi)    Reviewed the Engineering Consultants' Valuation of the
                  Properties underlying the Assets;

          (vii)   Reviewed historical operating and financial results of the
                  Properties underlying the Assets which included PV-10 Value,
                  proved reserves on a barrel of oil equivalent ("BOE") basis
                  and projected earnings before interest, taxes and
                  depreciation, depletion and amortization ("EBITDA") as
                  prepared by the Engineering Consultants and discussed with
                  senior management of the Company;

          (viii)  Reviewed and analyzed financial terms of similar transactions
                  in which public oil and gas companies liquidated partnerships
                  of which they were the general partner;

          (ix)    Reviewed and analyzed transactions involving the sale of oil
                  and gas companies we deemed comparable to the Partnership(s)
                  individually and collectively and to the Company;

          (x)     Reviewed and analyzed transactions involving the sale of oil
                  and gas properties we deemed comparable to the Properties
                  underlying the Assets;

          (xi)    Reviewed financial and market data for certain public
                  companies we deemed comparable to the Partnership(s)
                  individually and collectively and to the Company; and

          (xii)   Performed such other analyses and reviewed such other
                  information as we deemed appropriate.

In determining the CIBC Oppenheimer Valuation, we have relied upon and assumed,
without independent verification or investigation and at the direction of the
Committee, (i) the accuracy and completeness of all of the financial and other
information available to us from public sources or provided to us by the Company
and their representatives (including the Engineering Consultants), (ii) that the
reserve engineering reports supplied to us by the Engineering Consultants as
described in clause (v) above have been reasonably prepared and are based on
their best business judgment, (iii) that the information with respect to the
Partnership's ownership of the Assets, as provided to the Engineering
Consultants and to us was accurate in all respects, (iv) with respect to the
historical operating and financial results and projections provided to us as
described in clause and (vii) above, that such information and projections were
reasonably prepared and were based on the best currently available information,
estimates and good faith judgment of the Company's management and their
representatives (including the Engineering Consultants).

Not being experts in the geological evaluation of oil and gas reserves, we have,
with your consent, relied without independent verification upon the audit of the
reserve estimates prepared by the Engineering Consultants for the purpose of
estimating fair market value of the Assets. In addition, we have not made a
physical inspection of the Properties underlying the Assets, nor have we made
any independent evaluations, appraisals or inspections of the Company's or the
Partnership's other assets or the Company's or the Partnership's liabilities
(contingent or otherwise). We have not reviewed any relevant agreements which
may exist between the General Partner and the limited partners governing the
Partnership, nor have we considered the effect which the ownership structure of
the Partnership and the terms of the agreements of the Partnership may have upon
the fairness of the consideration offered by any general partner of the

The CIBC Oppenheimer Valuation is based upon analyses of the foregoing factors
in light of our assessment of general economic, financial, market and other
conditions and circumstances as of the date of this letter and any changes in
such conditions and circumstances may affect the validity or fairness of the
CIBC Oppenheimer Valuation. CIBC Oppenheimer disclaims any obligations to
update, revise or reaffirm the CIBC Oppenheimer Valuation. The CIBC Oppenheimer
Valuation reflects our estimate of the consideration that could have been
received by the Partnership in a sale of the Assets in an orderly manner in a
private market transaction in which neither buyer nor seller is under any
compunction to complete such transaction. The CIBC Oppenheimer Valuation falls
within a range of values which we believe, subject to the foregoing conditions,
represent possible fair market value estimates of the Partnership's interest in
the Assets. The CIBC Oppenheimer Valuation should not be viewed as a guarantee
of the price that a willing buyer might have paid for the Assets.

CIBC Oppenheimer, as part of its investment banking services, is regularly
engaged in the valuation of businesses and securities in connection with
mergers, acquisitions, underwritings, sales and distributions of listed and
unlisted securities and private placements. CIBC Oppenheimer has provided
certain investment banking and financial advisory services to the Company from
time to time, including acting as co-manager of the Company's Convertible
Subordinated Notes financing in November 1996 and lead manager of the public
offering of the Company's Common Stock in July 1995, and may be involved in
future investment banking activities on behalf of the Company. CIBC Oppenheimer
will also receive a fee upon delivery of this CIBC Oppenheimer Valuation. In the
ordinary course of business, CIBC Oppenheimer actively trades in the equity
securities of the Company for CIBC Oppenheimer's own account and for the
accounts of CIBC Oppenheimer's customers and, accordingly, may at any time hold
a long or short position in such securities.

Based upon and subject to the foregoing, and based upon such other matters as we
consider relevant, it is CIBC Oppenheimer's estimate that the value of Swift
Energy Managed Pension Assets 1988-A Ltd. interest in the Assets as of the date
hereof is $347,204.

This letter is being provided for the use of the Committee in its evaluation of
a possible proposal that the Partnership sell the Assets to the Managing General
Partner and dissolve and wind up its affairs. This letter is not intended to
confer rights or remedies upon any stockholder of the Company or any partner of
the Partnership and may not be relied upon by any person or entity other than
the Committee. Neither this letter nor the CIBC

                                      SWIFT ENERGY MANAGED PENSION ASSETS 1988-A
                                      97-003-133

Gentlemen:

At your request, we have made an audit of the reserves and future net cash flow
as of December 31, 1997, prepared by Swift Energy Company ("Swift") for certain
interests in Swift Energy Managed Pension Assets 1988-A. This audit has been
conducted according to the standards pertaining to the estimating and auditing
of oil and gas reserve information approved by the Board of Directors of the
Society of Petroleum Engineers on October 30, 1979. We have reviewed these
properties and where we disagreed with the Swift reserve estimates, Swift
revised its estimates to be in agreement. The estimated net reserves, future net
cash flow and discounted future net cash flow are summarized by reserve category
in Table 1 for both the 100% Fund Level Partnership and the Limited Partnership
Interest.

The discounted future net cash flow is not represented to be the fair market
value of these reserves and the estimated reserves included in this report have
not been adjusted for risk.

The estimated future net cash flow shown is that cash flow which will be
realized from the sale of the estimated net reserves after deduction of
royalties, ad valorem and production taxes, direct operating costs and required
capital expenditures, when applicable. Surface and well equipment salvage values
and well plugging and field abandonment costs have not been considered in the
cash flow projections. Future net cash flow as stated in this report is before
the deduction of state and federal income tax.

In the economic projections, prices, operating costs and development costs
remain constant for the projected life of each lease.

The reserves included in this study are estimates only and should not be
construed as exact quantities. Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available. Proved reserves are
estimated in accordance with the definitions contained in Securities and
Exchange Commission Regulation S-X, Rule 4-10(a). The definitions are included
in part as Attachment I.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented. The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December. Interim production to December 31, 1997, has been
estimated. No independent well tests, property inspections or audits of
operating expenses were conducted by our staff in conjunction with this study.
We did not verify or determine the extent, character, obligations, status or
liabilities, if any, arising from any current or possible future environmental
liabilities that might be applicable.

Swift Energy Company                    -2-                    February 10, 1998

In order to audit the reserves, costs and future net cash flows shown in this
report, we have relied in part on geological, engineering and economic data
furnished by our client. Although we have made a best efforts attempt to acquire
all pertinent data and to analyze it carefully with methods accepted by the
petroleum industry, there is no guarantee that the volumes of oil or gas or the
cash flows projected will be realized.

Production rates may be subject to regulation and contract provisions, and may
fluctuate according to market demand or other factors beyond the control of the
operator. The reserve and cash flow projections presented in this report may
require revision as additional data become available.

We are unrelated to Swift and we have no interest in the properties included in
the information reviewed by us. In particular:

         1.     We do not own a financial interest in Swift or its oil and gas 
                properties.

         2.     Our fee is not contingent on the outcome of our work or report.

         3.     We have not performed other services for or have any other
                relationship with Swift that would affect our independence.

If investments or business decisions are to be made in reliance on these
estimates by anyone other than our client, such person with the approval of our
client is invited to visit our offices at his expense so that he can evaluate
the assumptions made and the completeness and extent of the data available on
which our estimates are based.

Any distribution or publication of this report or any part thereof must include
this letter in its entirety.

                                Yours very truly,

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                                   SUPPLEMENT
                                       TO

                          OFFERING OF COMMON STOCK OF
                              SWIFT ENERGY COMPANY



         For the definition of capitalized terms herein which are not otherwise
defined, see "Glossary" in the Joint Proxy Statement/Prospectus.  Other
discussions which are cross-referenced in this Supplement are contained in the
Joint Proxy Statement/Prospectus, unless otherwise noted.

   
         Swift Energy Company ("Swift" or the "Company") is the Managing
General Partner ("Managing General Partner") of 63 Texas limited partnerships
(the "Partnerships"), including the Partnership, formed between 1986 and 1994
to invest in producing oil and gas properties.  Swift is asking limited
partners (referred to herein as "Investors") in the Partnership (and similarly
in the other 62 Partnerships) to approve a Proposal to sell all of the
Partnership's oil and gas assets to the Managing General Partner (the
"Proposal") for $3,314,557, which is a purchase price derived by choosing the
higher of two estimates of fair market value of those assets determined by
three independent Appraisers, and adding to that higher number a 7.5% premium.
    

   
         If the Proposal is approved by Investors in the Partnership and its
Companion Partnership, after the sale of all of its oil and gas assets the
Partnership will dissolve, wind up and terminate.  The Partnership will receive
cash for its oil and gas assets, which in turn is to be distributed to the
Investors in the Partnership (along with the net of all assets less liabilities
of the Partnership) in accordance with their respective percentage ownership
interests in the Partnership.  If Investors in the Partnership approve the
Proposal, then each Investor can elect, in their sole individual discretion, to
receive shares of Common Stock of the Company (without payment of any brokerage
commissions) instead of some or all of the cash which they are entitled to
receive upon the Partnership's liquidation.
    

   
         The reasons for and effects of the Proposals may be different for
investors in each of the Partnerships.  This Supplement has been prepared to
highlight for the Investors in the Partnership the particular risks, effects
and fairness of the Proposal to the Investors in the Partnership and to provide
information on the Partnership to its Investors, in connection with the
solicitation of proxies by the
    
<PAGE>   267
Managing General Partner for use at the Special Meeting of the Investors in the
Partnership in voting upon the Proposal and to transact such other business as
may be properly presented at the Special Meeting or any adjournments or
postponements thereof.

         BOTH THE VOTE UPON THE PROPOSAL AND ANY ELECTION MADE BY AN INDIVIDUAL
INVESTOR TO RECEIVE SHARES OF SWIFT ENERGY COMPANY COMMON STOCK ARE SUBJECT TO
NUMEROUS RISK FACTORS, INCLUDING THOSE HIGHLIGHTED BELOW.  SEE "RISK FACTORS"
IN THIS SUPPLEMENT AND IN THE JOINT PROXY STATEMENT/PROSPECTUS FOR A FULL
DISCUSSION OF ALL RISK FACTORS.

o        Substantial conflicts of interest exist because if the Proposal is
         approved by the Partnership and its Companion Partnership, the
         Managing General Partner will purchase all of the oil and gas assets
         from the Partnership while it serves as its Managing General Partner.

o        The purchase price for the Partnership's Property Interests may not be
         the highest possible price.

o        No independent representative negotiated the terms of the purchase
         price with the Managing General Partner.

o        No fairness opinion was acquired regarding the fairness of the
         purchase price.

   
o        The Managing General Partner may profit from acquisition of the
         Partnership's oil and gas assets by investing capital in order to
         develop non-producing reserves of the acquired Property Interests and
         possibly through improvement in oil and gas prices.
    

   
o        Estimates of distributions to Investors from continuing operations of
         the Partnership for the life of its reserves are higher than amounts
         anticipated to be received if Investors vote in favor of the Proposal.

         Compared to Continuing Operations."
    

o        An election by an Investor to receive shares of Swift Common Stock in
         lieu of cash distributable to Investors subjects such Investors to the
         risks of investing in the Company.

                                THE PARTNERSHIP

   
         The Partnership was formed over nine years ago and owns working
interests in producing oil and gas properties in six states in which its
companion partnership, Swift Energy Managed Pension Assets Partnership 1989-B,
Ltd.  ("Companion Partnership"), formed at approximately the same time and also
managed by the Managing General Partner, owns the non-operating interests. The
Partnership had expended all of its original capital contributions by the end
of October 1989.  The Partnership's oil and gas properties are generally evenly
divided between gas and oil properties, with approximately 50% of the
Partnership's 1997 production and approximately 60% of its total proved
reserves at December 31, 1997, attributable to natural gas.  The Partnership
has, from time to time, performed workovers and recompletions on wells in which
the Partnership has Property Interests, using funds advanced by the Managing
General Partner or third parties to perform these operations, which amounts
have been subsequently repaid. The Partnership owns interest in 643 wells in 34
fields.
    

   
         The following table presents information on those fields in which the
Partnership has Property Interests which constitute 10% or more of the
Partnership's PV-10 Value at December 31, 1997.  The Partnership's "PV-10
Value" is the estimated future net cash flows (using unescalated prices) from
production of proved reserves attributed to the Partnership's Property
Interests, discounted to present value at 10% per annum.  Attachment D to this
Supplement is the report dated February 10, 1998 of the audit by H.J. Gruy and
Associates, Inc., Independent Petroleum Consultants, of the oil and gas
reserves underlying the Partnership's Property Interests, and future net cash
flow expected from the production of those reserves as of December 31, 1997,
presented both for the Partnership as a whole and as to those reserves solely
attributable to the Investors in the Partnership.  This report has not been
updated to include the effect of production since year-end 1997.  In estimating
these reserves, the Managing General Partner, in accordance with criteria
prescribed by the Securities and Exchange Commission, has used year-end 1997
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.  The Managing General
Partner is not aware of any favorable or adverse event causing a significant
change in the estimated amount (as set forth in Attachment D hereto, which is
the report of H.J. Gruy and Associates, Inc.) of proved reserves of the
properties in which the Partnership owns an interest between December 31, 1997
and the date of this Supplement.
    

   
         The information below includes the location of each field in which the
Partnership has an interest, the number of wells and operators, together with
information on the percentage of the Partnership's total PV-10 Value on
December 31, 1997 attributable to each of these fields.  Information is also
provided regarding the percentage of the Partnership's 1997 production (on a
volumetric basis) from each of these fields.  Of the remaining other fields in
which the Partnership owns a Property Interest, 21 of such fields each comprise
less than 1% of the Partnership's PV-10 Value at December 31, 1997, and the
PV-10 Value of each of the other ten fields averages less than 3% of the
Partnership's PV- 10 Value at the same date.

</TABLE>
    

         The Partnership's total assets at year-end 1997 were $3,871,732 and
the PV-10 Value of its total proved reserves at the same date was $4,009,417.
Based upon the audit of the Partnership's Total Proved Reserves at year-end
1997, those reserves were comprised of the following three categories:

                  Proved Producing(1)              83%
                  Behind-Pipe(2)                    5%
                  Non-Developed(3)                 12%
                                                  ---
                                                  100%
                                                  === 

- -------------

         (1) Proved producing reserves are reserves that can be expected to be 
recovered through existing wells with existing equipment and operating methods.

         (2) Behind-pipe reserves are proved reserves that will not contribute
to cash flows until recompletion projects have been implemented to place them
into production.  The impact of these recompletion projects will also be limited
until the costs of implementation have been recovered.  In general, it is not
appropriate to bring behind-pipe reserves into production until the formation
that is currently producing has been depleted.  Premature recompletions can lead
to permanent reductions in a well's proved reserves.

         (3) Non-developed reserves are reserves that are expected to be 
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion.  Therefore,
significant additional expenditures are usually required before undeveloped
reserves can be produced.

         Attachment Dis the annual reserves audit and independent reserves
report prepared by H.J. Gruy and Associates, Inc. as to the Partnership's
remaining proved oil and gas reserves available for production over a period in
excess of 15 years.  These quantities have been given a value based upon prices
for oil and gas at December 31, 1997.  The value is determined based upon the
assumption that these prices will remain in effect over the life of these
reserves.  This value is then discounted at 10% per year to arrive at





                                       4
<PAGE>   270
   
the value (in today's dollars) of these revenues ("PV-10 Value").  This PV-10
Value for the Partnership's Property Interests is $4,009,417.  It is also
estimated that $343,575 in future capital costs must be spent to develop the
Partnership's non-producing reserves.
    

                                  RISK FACTORS

   
o        Although the fair market value of the Property Interests proposed to
         be purchased from the Partnership by the Managing General Partner was
         based upon a determination by three independent Appraisers, no opinion
         was acquired as to the fairness of the ultimate purchase price, which
         was determined in the Managing General Partner's sole judgment by
         adding a 7.5% premium over the higher of the two fair market value
         estimates for the Partnership's Property Interests determined by the
         Appraisers.  Therefore, the purchase price was not determined on an
         impartial basis by a party not involved in the transaction, and
         another party intent upon purchasing the Property Interests in the
         Partnership might have offered a different purchase price.  There is
         no guarantee that the purchase price represents the highest possible
         price that could be received for the Partnership's Property Interests
         in all circumstances.  It is possible that a higher (or lower) price
         might be received if these assets were sold on another basis, such as
         at auction or in negotiated sales.  Furthermore, the assessment of the
         value of the Partnership's proved non-producing reserves could vary
         widely, given the typical discounting in valuing non-producing
         reserves.
    

   
o        The Managing General Partner did not retain an independent
         representative to act on behalf of the Investors in the Partnership in
         structuring and negotiating the terms or price of the Proposal or the
         purchase price.  The price at which it is proposed that the Company
         purchase the Property Interests from the Partnership has not been
         negotiated at arm's length and is subject to significant conflicts of
         interest between the Company acting as the purchaser of such
         properties while serving as the Managing General Partner of the
         Partnership.  If an independent representative had been retained for
         the Partnership, the terms or price might have been different and
         possibly more favorable to Investors.
    

o        The fair market value (excluding the 7.5% premium) established for the
         Partnership's Property Interests is based upon the Appraisers'
         evaluation of that value.  Year-end 1997 prices, along with other
         current market factors, were used as a starting point for the
         Appraisers' analysis, and prices and costs were then escalated at a
         rate of 3.5% per year over 15 years.  Substantial increases in the
         prices for oil and gas in the future might result in Investors
         receiving higher distributions from continued operations of the
         Partnership, although the effect of any higher prices is somewhat
         limited because the Partnership has already produced a substantial
         majority of its oil and gas reserves.

   
o        In order to effectuate the sale of its Property Interests, the
         Proposal must not only be approved by the Partnership, but a similar
         Proposal must be approved by the Companion Partnership.  This
         requirement exists because of the significant lowering of the value of
         either (i) a working interest burdened by a large non- operating
         interest controlled by a different party, or (ii) a non-operating
         interest in properties the operations of which are controlled by a
         third party.  Therefore, even if the Investors in the Partnership
         approve the Proposal to sell their Property Interests, this may not be
         done without the approval of a similar Proposal by investors in the
         Companion Partnership.  If either Partnership does not approve its
         Proposal, then the Managing General Partner will
    





                                       5
<PAGE>   271
   
         reassess  the value of the Property Interests of each Partnership and
         attempt to formulate a new proposal for the investors in each such
         Partnership.
    

   
o        Investors that are subject to federal income tax on an investment in
         the Partnership are required to recognize gain or loss on the sale of
         oil and gas assets by the Partnership and the subsequent liquidation
         of the Partnership.  The amount and character of the gain or loss
         depends on certain factors specific to individual Investors.  It is
         anticipated that Investors that acquired their interests in the
         original offering will recognize a gain for federal income tax
         purposes.  Any tax that may be due must be paid even if such Investors
         choose to acquire Company Common Stock with some or all of their
         proceeds from property sales.  Investors also should consult their
         individual tax advisors to determine whether they are subject to any
         state tax.  For a broader discussion of the tax consequences,
         Investors should read "Federal Income Tax Consequences of Adoption of
         the Proposals" in the Joint Proxy Statement/Prospectus, and "Summary
         of Federal Income Tax Consequences" in this Supplement.
    

   
o        Investors that are Tax Exempt Plans will be subject to taxation on the
         Partnership's sale of property and the liquidation of the Partnership,
         while other Tax Exempt Plans are not expected to be subject to
         taxation on the sale and liquidation.  See "Summary of Federal Income
         Tax Consequences--Tax Treatment of Tax Exempt Plans--Debt-Financed
         Property" in this Supplement.
    

   
o        As currently proposed, Investors that subscribe for Company Common
         Stock pursuant to this Offering may not receive some or all of the
         cash which would otherwise be distributed to them as part of the
         liquidating distribution of their Partnership.  The amount of any cash
         liquidating distribution they actually receive depends upon the
         purchase price to be paid for any Company Common Stock they elect to
         and are entitled to receive pursuant to the terms of this Offering.
         For federal income tax purposes, Investors subscribing for shares of
         Company Common Stock will be treated as though they had purchased
         those shares for cash, even though they never had actual possession of
         the cash used to acquire the shares.  Additionally, the fact that such
         Investors elect to acquire Company Common Stock rather than receive
         cash in liquidation of their Partnership interests will not affect the
         federal income tax consequences attending the liquidation of their
         Partnership interests.  Because the purchase of shares of Company
         Common Stock will reduce the cash received by Investors upon the
         Partnership's liquidation, to the extent that Investors owe federal
         income tax as a result of the liquidation, they may not receive
         sufficient cash to pay some or all of any tax they may owe on the
         liquidation.  Such Investors owing tax as a result of the liquidation
         will have to pay such tax from sources other than any cash liquidating
         distribution from the Partnership.
    

See "Risk Factors" in the Joint Proxy Statement/Prospectus.

                             CONFLICTS OF INTEREST

   
         There are substantial conflicts of interest which exist by virtue of
the Managing General Partner acting in that capacity on behalf of the
Partnership while at the same time acting as the proposed purchaser of all of
the oil and gas assets of the Partnership.  These conflicts of interest are
discussed below.
    

o        The terms of the Proposal are established by the Company which is also
         the Managing General Partner of the Partnership.





                                       6
<PAGE>   272
o        Neither the Managing General Partner nor a majority of its independent
         directors retained an independent representative to act on behalf of
         the Partnership's Investors for the purposes of negotiating the terms
         upon which any such sale to the Managing General Partner would be made
         or for the preparation of a report concerning the fairness of the
         entire transaction.

See "Summary--Conflicts of Interest" and "Conflicts of Interest" in the Joint
Proxy Statement/Prospectus.

                                SPECIAL FACTORS

BACKGROUND AND PURPOSE OF THE PROPOSAL

   
         [VARIABLE PARA. BY P'SHIP TYPE] A number of factors have led to the
decision of the Company in its capacity as Managing  General Partner to solicit
approval of the Proposal by Investors in the Partnership.  As contemplated when
the Partnership was organized, and given the expenditure of virtually all of
the Partnership's capital to purchase producing properties over eight years
ago, the production from Partnership oil and gas assets declined over time.  It
was always anticipated that a time would arrive when the Managing General
Partner would propose that the business of the Partnership be concluded, its
assets sold or otherwise disposed of, and the Partnership liquidated and
dissolved.  The general improvement in the prices for natural gas over the last
several years, relative to such prices in the mid- 1990's, make this an
appropriate time, especially in light of the age of the Partnership, to
consider the Proposal to sell the Partnership's Property Interests.  The
structure being proposed, which involves the sale of the Partnership's oil and
gas assets to the Managing General Partner, is being submitted for approval by
Investors in an attempt to realize the highest value for those assets.  For the
reasons set out below, the Managing General Partner believes that the Proposal
is fair to Investors in the Partnership, given that the purchase price for
these assets has been determined by taking the higher of two fair market value
estimates by three independent Appraisers and adding to it a 7.5% premium.
    

         Approval of the Proposal will have the following effects:

   
1.       The Managing General Partner will purchase all of the oil and gas
         assets of the Partnership, provided its Companion Partnership has
         approved its proposal.
    

   
2.       When the Partnership sells all of its oil and gas assets, it will be
         required to liquidate and distribute its remaining assets (principally
         the cash proceeds from the sale) to its partners (including the
         general partners) in accordance with their respective ownership
         interests in the Partnership.
    

3.       Investors will be given the option of electing to receive shares of
         Swift Common Stock, in amounts that they choose on an individual
         basis, in lieu of some or all of the cash they would be entitled to
         receive upon the Partnership's liquidation.

   
4.       Investors in the Partnership will be taxed on the sale of the
         Partnership's oil and gas assets, although such sale is expected to
         result in a taxable gain to Investors that acquired their interests in
         the original offering.

PROPOSED PURCHASE PRICE

   
         As discussed in greater detail below, the Petroleum Engineering
Consultants estimated that the aggregate fair market value of the Partnership's
Property Interests as of December 31, 1997 is $3,083,309.  CIBC Oppenheimer
estimated a fair market value of the same Property Interests at the same date
of $3,028,036.  The Special Transactions Committee chose the higher of these
two determinations as the "Fair Market Value" for the purchase of these
interests and the Board of Directors of the Company determined to pay a 7.5%
premium ($231,248) above the Fair Market Value to purchase the Partnership's
Property Interests, resulting in a purchase price of $3,314,557.  This compares
to the total purchase price for all of the oil and gas assets of all 63
Partnerships which are considering similar proposals of approximately $81
million.  The valuation estimates of the Appraisers are attached to this
Supplement and incorporated herein by reference as follows:   Attachment A is
the fair market value estimate of H.J. Gruy and Associates, Inc., Attachment B
is the fair market value estimate of J.R. Butler and Company, and Attachment C
is the fair market value estimate of CIBC Oppenheimer Corp.  The PV-10 Value
prepared on an annual basis by H.J. Gruy of the same Property Interests as of
the same date is $4,009,417.
    

REASONS FOR THE PROPOSAL

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

   
         Current Liquidating Distribution Lowers Volatility Risk.  Although
Investors already have received cash distributions from the Partnership in
excess of their original capital contributions, future cash distributions are
likely to decrease over time.  The Partnership has been in existence for over
nine years.  The Managing General Partner believes that the ability to receive
the estimated liquidating distribution in one lump sum at this time, rather
than in smaller amounts over a longer period, is one of the benefits of the
Proposal, without the risk of such distributions being negatively affected by
oil and gas price decreases and the inherent risks associated with geological,
engineering and operational matters.  It is also the Managing General Partner's
belief that improvements over the last several years in the level of gas
prices, relative to such prices in the mid-1990's, makes 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
future prices and market volatility cannot be predicted with any accuracy.
    

   
         Decreasing Cash Flow While Expenses Continue.  The Partnership's oil
and gas reserves are expected to continue to decline as remaining reserves are
produced.  Declines in well production are based principally upon the maturity
of the wells, not on market factors.  These declines will continue to occur
while oil field overhead and operating costs ($80,297  in 1997) and direct
general and administrative expenses ($155,295 in 1997) continue, which are
relatively fixed amounts.  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.  By accelerating the liquidation of the Partnership, those future
administrative costs will be avoided by the Partnership.
    

         Limited Partners' Tax Reporting.  Each Investor will continue to have
an income tax reporting obligation with respect to his Units as long as the
Partnership continues to exist.  There is no trading





                                       8

market for the Units, so Investors generally are unable to dispose of their
Units.  See "Business of the Partnership Business and Financial Condition--No
Trading Market" in this Supplement.  Following the sale of the Partnership's
Property Interests and dissolution of the Partnership, Investors will realize
gain or loss, or a combination of both, under federal income tax laws.  See
"Summary of Federal Income Tax Consequences--Taxable Gain or Loss upon Sale of
Properties" herein.  Thereafter, Investors will have no further tax reporting
obligations with respect to the Partnership.  The dissolution of the
Partnership will also allow Investors to take a capital loss deduction for
syndication costs incurred in connection with formation of the Partnership.

Partnership" in this Supplement.

COLLECTIVE ANALYSIS OF PURCHASE PRICE; PREMIUM OVER FAIR MARKET VALUE

         The Special Transactions Committee selected H.J. Gruy and Associates,
Inc. ("H.J. Gruy" or "Gruy"), J.R. Butler and Company ("J.R. Butler" or
"Butler"), which are both petroleum engineering consultants, and CIBC
Oppenheimer Corp.  ("CIBC Oppenheimer"), an investment banking firm, to
estimate the fair market value of the Property Interests of each of the
Partnerships.  Collectively, H.J. Gruy, J.R. Butler and CIBC Oppenheimer are
referred to herein as the "Appraisers," and H.J. Gruy and J.R. Butler together
are sometimes referred to herein as the "Petroleum Engineering Consultants."

         The following subsections of the "Special Factors" section of the
Joint Proxy Statement/Prospectus should be reviewed for information concerning
the selection and qualification of the Appraisers and the parameters of the
valuation estimates: "Independent Appraisal of the Fair Market Value of
Property Interests of the Partnerships," "Qualification of Appraisers," and
"Fair Market Value."

   
         The Petroleum Engineering Consultants arrived at a fair market
valuation estimate of the Partnership's Property Interests based upon appraisal
of the projected discounted cash flow from its various Property Interests.  On
the other hand, the investment banking firm of CIBC Oppenheimer made a
valuation estimate based upon the application of multiple quantitative and
qualitative factors.  The quantitative factors include, among other things, a
review of relevant valuation criteria from comparable acquisitions of both oil
and gas properties and companies that are predominantly active in the oil and
gas industry, and a review of valuation criteria for relevant publicly traded
oil and gas companies.
    

         The process used by the Petroleum Engineering Consultants in preparing
their valuation estimate is discussed at length in the Joint Proxy
Statement/Prospectus under "Special Factors--Valuation by Petroleum Engineering
Consultants." As described therein, the Petroleum Engineering Consultants
individually audited the estimate of present value of future net cash flows
from the 44 property groups in which Property Interests are owned by the
Partnerships to whom similar proposals are being made to sell all of their oil
and gas assets and liquidate their Partnerships.  The Partnership owns Property
Interests in eleven of these property groups.  The Petroleum Engineering
Consultants began their analysis based upon the year-end 1997 PV-10 Value of
each property audited by H.J. Gruy and together they re-evaluated reserve
quantities, projected operating costs and cash flows.  The present value of
this reserves analysis was then derived by escalating year-end 1997 prices
($2.38 per MMBtu and $16.00 per barrel before adjustments for Btu content for
gas and gravity variances for oil as well as transportation charges and





                                       9
<PAGE>   275
geographic location) and costs by 3.5% per year for 15 years.  This present
value was then adjusted for various individual field risks and risk adjustments
of proved non-producing reserves and proved undeveloped reserves.  The result
of this collective analysis by the Petroleum Consulting Engineers was their
estimation that the fair market value of Property Interests owned by the
Partnership was $3,083,309 as of December 31, 1997.

   
         The methodology used by CIBC Oppenheimer to prepare its valuation
estimate is discussed at length under "Special Factors--Valuation by CIBC
Oppenheimer" in the Joint Proxy Statement/Prospectus.  CIBC Oppenheimer's
evaluation of the Partnership's Property Interests began with the PV-10 Value
of each property group, as calculated by Swift and audited by H.J. Gruy, which
Gruy report dated February 10, 1998 is Attachment D to this Supplement.  CIBC
Oppenheimer then divided the property groups into two categories.  Those
property groups with reserves consisting primarily of proved developed
producing reserves were placed in the "Conventional Case" category.  Those
property groups with significant proved developed non-producing or undeveloped
reserves were placed in the "Non-Conventional Case" category.  [NEXT IS
VARIABLE SENTENCE:]  The Partnership has interests in property groups which
were in both the "Conventional Case" and the "Non-Conventional Case"
categories.  CIBC Oppenheimer then valued each property group by applying the
multiples discussed under "Special Factors--Valuation by CIBC
Oppenheimer--Valuation Multiples" in the Joint Proxy Statement/Prospectus to
each property group's PV-10 Value, proved reserves on a BOE basis, and
projected 1998 EBIDTA.  A separate set of multiples was used for property
groups in the Conventional Case category and the Non-Conventional Case
category, respectively.  This provided CIBC Oppenheimer with three estimated
values for each property group.  The average of these three values yielded CIBC
Oppenheimer's estimation of the fair market value of each property group.  CIBC
Oppenheimer then allocated the appropriate portion of each property group's
estimated fair market value to the Partnership based upon the Partnership's
Property Interests in each property group.  The result of this analysis by CIBC
Oppenheimer was an estimation that the fair market value of the Partnership's
Property Interests was $3,028,036 on December 31, 1997.
    

   
         The Special Transactions Committee has determined that, in keeping
with the definition of Fair Market Value, the higher of these two estimations
of fair market value, or $3,083,309, represents the Fair Market Value of the
Partnership's Property Interests.  Accordingly, the fair market estimation of
the Petroleum Consulting Engineers and the fair market value determined by CIBC
Oppenheimer were compared to each other and the higher of the two was chosen as
the Fair Market Value of the Property Interests owned by the Partnership.  The
variation between the fair market value estimate of the Partnership's Property
Interests prepared by the Petroleum Consulting Engineers, on one hand, and CIBC
Oppenheimer on the other was 2%.
    

DETERMINATION OF PREMIUM OVER FAIR MARKET VALUE BY THE COMPANY

   
         The Special Transactions Committee presented its recommendation to the
Board of Directors of the Company as to the Fair Market Value of the Property
Interests of the Partnership.  The Board of Directors of the Company then
determined that paying a 7.5% premium over the Fair Market Value of the
Partnership's Property Interests was appropriate and fair based upon the
factors and for the reasons discussed below.  Because the Company has served as
Managing General Partner of the Partnership for over nine years, it is
intimately familiar with the Property Interests owned by the Partnership.  The
Managing General Partner believes that if the Property Interests were to be
sold to a third party purchaser that was not equally familiar with those
interests, it is likely that the purchaser would discount the purchase price to
account for that lack of familiarity and associated risks.  If these interests
are purchased by the
    





                                       10
<PAGE>   276
   
Company, then the additional cost and personnel often inherent in making a
property acquisition are not required, because the files and deed records
already exist in the Company's lease and computer systems, and conveyance and
title issues do not exist.
    

         In the judgment of the Company, the purchase of the Partnership's
Property Interests together with interests in many of the same properties owned
by other Partnerships at approximately the same time will result in
efficiencies to the Company in aggregating such interests.  Swift's long-term
knowledge of the risks involved in these properties means that it is in a
better position to evaluate these risks than third parties.

         Based upon the Company's experience in purchasing properties, the lack
of additional costs often incurred in purchasing oil and gas properties in
which the purchaser has owned no interest, and the Company's intimate
familiarity with these Property Interests and consequent ability to evaluate
acquisition risks, it was deemed appropriate to pay a premium representing the
benefit to the Company arising from these factors.

   
         The amount of the premium principally was based upon management's
experience in purchasing properties which contain both producing reserves and
drilling potential, without any statistical or analytical study prepared by the
Company in the course of determining the amount of this premium.  Since 1979,
the Company, on behalf of itself and others, has gained a wide range of
experience with the valuation of oil and gas properties and the prices for
their purchase and sale, having purchased $478 million of such properties in
129 separate transactions.  Other purchasers might have determined it
inappropriate to pay  a premium, or if so, to pay a premium based upon other
factors or in a different amount.  Because there has been no independent third
party involved in the decision to pay this premium or in the determination of
its amount, and no fairness opinion has been requested regarding this premium,
conflicts of interest exist in its determination, although the Managing General
Partner believes, based upon its knowledge of the oil and gas industry, its
knowledge of the properties involved, its experience in purchasing and selling
oil and gas properties, and the benefits from purchasing the Property Interests
which are particular to the Company, that the amount being offered to the
Partnership to purchase its Property Interests is fair.
    

"SPECIAL FACTORS" SECTION IN THE JOINT PROXY STATEMENT/PROSPECTUS

   
         The Special Factors section in the Joint Proxy Statement/Prospectus
contains a full discussion of the determination of the purchase price proposed
to be paid by the Managing General Partner to purchase the Partnership's
Property Interests.  In addition to those topics discussed at length in this
Supplement, the Joint Proxy Statement/Prospectus addresses alternative
transactions that were considered but not proposed for the Partnership and the
other 62 partnerships to whom similar proposals are being made simultaneously.
It also contains information regarding the prior relationships between the
Appraisers, the Partnerships and the Managing General Partner, the absence of a
request that an independent representative negotiate the terms of the purchase
of the Partnership's Property Interests by the Managing General Partner, the
manner in which expenses are to be borne for the transaction, the Managing
General Partner's source of funds to purchase the Partnership's Property
Interests, and the benefits that the Managing General Partner would receive
from purchasing such Property Interests.

ESTIMATES OF LIQUIDATING NET CASH DISTRIBUTION AMOUNT IF THE PROPOSAL IS
APPROVED

   
         The purchase price proposed to be paid to the Partnership for its oil
and gas assets is the Fair Market Value plus the purchase premium.  As is the
case with all oil and gas properties purchases, the purchase is proposed to be
made as of the date which the properties were evaluated (in this case December
31, 1997). A portion of the reserves used to establish the Fair Market Value
has been produced during 1998.  Most of the net revenue received by the
Partnership from the sale of such production since the proposed purchase date
(December 31, 1997) has been distributed to the partners during 1998 through
quarterly cash distributions or, to the extent not already distributed, will be
distributed as part of the Partnership's liquidating distribution.
Accordingly, the actual purchase price which will be paid to the Partnership
will be reduced by the amount of net production revenue received by the
Partnership after December 31, 1997.
    

   
         Set forth in the table below are estimated net proceeds that the
Partnership may realize from the sale of the Partnership's Property Interests,
estimated expenses of the related dissolution and liquidation of the
Partnership and estimated interim net cash distributions from January 1, 1998
until September 30, 1998, resulting in an estimate of the amount of net cash
distributions available for partners as a result of such sale.

         Eligible Purchasers.  The minimum number of shares which can be
         purchased by an Eligible Purchaser is a round lot of 100 shares.
         Based upon estimated net cash distribution of $31.53 per $100 Unit,
         the number of Units shown above is the minimum number of Units which
         it will be necessary for an Investor to own in order to purchase a
         minimum 100 share round lot of Swift Common Stock without providing
         any additional funds from other sources.  This calculation is based
         upon an assumed purchase price of Swift Common Stock of $18.00 per
         share (which is the same price upon which the proforma financial
         statements contained in the Joint Proxy Statement/Prospectus are
         based) for an aggregate purchase price for 100 shares of Swift Common
         Stock of $1,800.  The minimum number of Units shown is subject to
         change, based upon the price for Swift Common Stock at a future date
         as specified under "Offering of Shares of Swift Energy Company Common
         Stock if Investors Approve the Proposal--Offer of Swift Common
         Stock--Purchase Price" in this Supplement.   However, if an Eligible
         Purchaser has interests in more than one Partnership, the cash
         distributions he will be entitled to receive may be aggregated to meet
         the minimum share purchase requirement of a round lot of 100 shares.
    

ESTIMATES OF NET CASH DISTRIBUTIONS AVAILABLE FROM CONTINUED OPERATIONS

   
         If the Partnership were to retain its Property Interests until they
have reached their economic limit, the table below estimates the return to
Investors, without regard to amounts distributable to the General Partners,
discounted to present value, based upon 1997 year-end pricing without
escalation and upon the discount assumptions used above.  The estimates of the
present value of future net cash distributions have been further reduced by
estimates of 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.
The following estimated future net revenues do not take into account any
additional costs which might be incurred by the Partnership due to needed
future maintenance or remedial work on the properties in which the Partnership
has an interest, which would reduce such net revenues.

         Partnership as of December 31, 1997.

(5)      Based upon the Partnership's reserves until they have reached their
         economic limit.

(6)      Discounted at 10% per annum.

         The proceeds of all sales, to the extent available for net cash
distribution, are to be distributed to the partners in accordance with the
Partnership's limited partnership agreement.  The amounts finally distributed
will depend on results of operations until liquidation of the Partnership,
final costs and other contingencies and circumstances.

   
FAIRNESS OF PROPOSED SALE OF ASSETS TO THE MANAGING GENERAL PARTNER
  AS COMPARED TO CONTINUING OPERATIONS
    

   
         Based on the above tables, it is estimated that an Investor could
expect to receive $31.53 per $100 Unit upon sale of the Partnership's Property
Interests at September 30, 1998.  In comparison, it is estimated that an
Investor could expect to receive $33.95 per $100 Unit, discounted to present
value at 10% per annum ($53.91 per $100 Unit on an undiscounted basis) if the
Partnership continued operations.  The Managing General Partner believes that
the Proposal to sell the Partnership's Property Interest as compared to
continuing operations is fair to Investors for the reasons discussed below.
    

   
         Although the estimates contained in the two tables above show that
estimated net cash distributions to Investors (based on net present value) from
continued operations would be approximately 8% higher than estimated net cash
distributions from selling the Partnership's Property Interests and liquidating
the Partnership currently, the Managing General Partner believes there is a
substantial advantage in receiving the liquidating net cash distribution in one
lump sum at this time.  The estimates of net cash distributions from continued
operations are based upon 1997 year- end pricing.  It is highly likely that
over such a long period of time, oil and gas prices will vary often and
possibly widely, as has been demonstrated historically, from the prices used to
prepare these estimates.  Continued operations over such a long period of time
subject Investors to the risk of receiving lower levels of net cash
distributions if oil and gas prices over this period are lower on average than
those used in preparing the estimates of net cash distributions from continued
operations.  Continued operations also subject Investors' potential net cash
distributions 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.  The Managing General Partner also believes that there
is an advantage to Investors taking any funds to be received upon liquidation
and redeploying
    





                                       15
<PAGE>   281
those assets in other investments, rather than continuing to receive decreasing
levels of net cash distributions over such a long period of time.

   
         Because there is no active trading market for Units in the
Partnership, the only other comparable value for Units is the 1997 "Unit
Value," which, as explained below, is the amount calculated on an annual basis
under the terms of the limited partnership agreement at which the Managing
General Partner can offer to repurchase Units from Investors.  As of January 1,
1997, this "Unit Value" was $54.65 per $100 Unit.  In 1997, the Investors
received net cash distributions of $12.63 per $100 Unit, and are estimated to
receive another $8.38 per $100 Unit before September 30, 1998, which converts
to a comparable value of $33.64 per $100 Unit before any adjustments to
quantities of reserves or oil and gas prices during this almost two year
period.  Under the terms set out in the limited partnership agreement, each
year the Managing General Partner is required to furnish to Investors the Unit
Value, and Investors have the right to present their Units for purchase by the
Managing General Partner for the Unit Value.  The Unit Value amount is
determined on an entirely different basis than the estimates of fair market
value by the Appraisers.  Furthermore, the Unit Value was calculated over one
year ago, with a valuation date of January 1, 1997, as opposed to the date for
assessment of Fair Market Value being December 31, 1997. Because of significant
changes in oil and gas prices within a year's time, in addition to the changes
in reserve quantities during that period, the calculation of Unit Value as of
January 1, 1997, and the Fair Market Value as of December 31, 1997, are not
comparable. Unit Value is derived by taking 70% of the present value of proved
oil and gas reserves (discounted at 10% per annum) calculated on an escalated
pricing basis, plus cash and accounts receivable, less outstanding debts and
obligations of the Partnership.
    

         Although the PV-10 Value of the Partnership's Property Interests is
higher than the purchase price proposed if the Proposal is approved, the
Managing General Partner does not believe that the PV-10 Value accurately
reflects the amount that oil and gas industry members are currently paying to
purchase producing properties on the open market.

FAIRNESS OF PROPOSED SALE

   
         The Managing General Partner believes that the entire transaction
related to the Proposal involving the proposed method of sale of the
Partnership's Property Interests is fair to Investors for the following
reasons, without giving any particular weight to any reason:
    

   
         1.      The Managing General Partner believes that the most important
                 element of the Proposal is the determination of the Fair
                 Market Value of the Partnership's Property Interests.  The
                 price to be paid by the Company to purchase the Partnership's
                 Property Interests was determined in the Managing General
                 Partner's sole judgment by adding a 7.5% premium to the higher
                 of the two estimates by the Appraisers of the fair market
                 value of the Partnership's Property Interests.  Two of the
                 three Appraisers are qualified independent petroleum
                 engineering firms and the other is an investment banking firm.
                 The factors and methods used by the Appraisers in determining
                 Fair Market Value are discussed in detail under "Special
                 Factors--Independent Appraisal of the Fair Market Value of
                 Property Interests of the Partnerships", "--Fair Market
                 Value," "--Valuation by Petroleum Engineering Consultants,"
                 "--Valuation by CIBC Oppenheimer" and "--Collective Analysis
                 of Purchase Price" in the Joint Proxy Statement/Prospectus.
    





                                       16
<PAGE>   282
   
         2.      No transaction will take place unless the Proposal is approved
                 by Investors holding at least a majority of the interests in
                 such Partnership (without any vote by the Managing General
                 Partner) and a similar Proposal is approved by the
                 Partnership's Companion Partnership.
    

         3.      The Special Transactions Committee made the determination as
                 to the retention of the Appraisers and approved the fair
                 market value estimates provided by the Appraisers and
                 recommended the reports of the Appraisers to the Board of
                 Directors of the Company.  The Special Transactions Committee
                 is comprised solely of independent directors of the Company.

   
         4.      If the Proposals are approved by investors in any of the 63
                 Partnerships considering similar proposals, it is likely that
                 the Managing General Partner will expend the capital necessary
                 to develop non- producing reserves on the Property Interests
                 purchased by the Managing General Partner from those
                 Partnerships.  If all of the Property Interests which are the
                 subject of the Proposals are acquired by the Company, such
                 Property Interests in the aggregate will constitute less than
                 20% of the Company's total assets.  Because the Managing
                 General Partner would be the beneficiary of any such increase
                 in value, the Managing General Partner is hereby offering to
                 Eligible Purchasers the opportunity to purchase up to
                 2,500,000 shares of Common Stock of the Company.  There is no
                 requirement that any purchase of Swift's Common Stock be made.
                 See "Offer of Swift Common Stock" below.
    

   
         5.      In structuring the Proposal and related transactions, the
                 Managing General Partner considered that any sale of
                 Partnership Property Interests, whether to the Managing
                 General Partner or to a third party, would be a taxable
                 transaction.  Thus, if an Investor subject to federal income
                 tax chooses to use the proceeds received on liquidation of
                 that Investor's Partnership to purchase Swift Common Stock,
                 tax will still have to be paid on the amount of any taxable
                 income resulting from the Partnership's sale of oil and gas
                 assets, without regard to whether the Investor has cash
                 proceeds remaining from his liquidating distribution to pay
                 such tax.
    

   
         The determination by the Special Transactions Committee to pay the
purchase premium, the independent Appraisers' determination of the Fair Market
Value of the Property Interests, and the payment of a 7.5% premium do not
necessarily remove the substantial conflicts of interest which exist in the
transaction between the Managing General Partner serving in that capacity on
behalf of the Partnership and also acting as the purchaser of the Property
Interests from the Partnership.  No fairness opinion was requested or received
regarding the ultimate purchase price to be paid by the Managing General
Partner to purchase the Partnership's oil and gas assets.  The Managing General
Partner determined that rather than setting the purchase price for Partnership
Property Interests itself, it would be preferable to request three different
independent Appraisers to determine two sets of fair market values at which
such Property Interests should be purchased, and then to choose the higher of
those two values.  The Company believes that when the Appraisers rendered their
opinions as to the "fair market value" of the Partnership's Property Interests,
inherent within their appraisal opinions were the Appraisers' determination
that these "fair market values" were "fair," or such determinations would not
have been made.  Consequently, no independent fairness opinion was requested
regarding "fair market values" or upon the premium.  The Managing General
Partner believes that adding a 7.5% premium to the highest of the two fair
market value determinations made by the three Appraisers only serves to
increase the amount to be paid to Investors
    





                                       17
<PAGE>   283
   
upon liquidation of the Partnership and does not require a separate fairness
opinion.  The determinations by a third party purchaser as to the purchase
price might be more or less than that being proposed by the Managing General
Partner as a purchase price for these Property Interests.
    

   
         The determination to submit the Proposal to Investors in which the
Company would purchase the Property Interests of the Partnership was deemed by
the Managing General Partner to be the most appropriate time and method for
liquidation of the Partnership.  This decision was made in light of full
consideration by the Managing General Partner of its fiduciary obligations to
Investors.  Furthermore, the decision to use three Appraisers, rather than one,
and to have the Appraisers actually set the fair market value for purchase of
the Property Interests, rather than the Managing General Partner setting that
value and requesting a fairness opinion, were based upon the Managing General
Partner's consideration of the substantial conflicts of interest which exist in
the transactions covered hereby.
    

See "Special Factors--Fairness of Proposed Sale" in the Joint Proxy
Statement/Prospectus.

MANAGING GENERAL PARTNER BENEFITS

   
         Benefits accruing to the Company resulting from the purchase of the
Partnerships' Property Interests include the following:  the Managing General
Partner will share the benefits available to Investors through liquidating its
Partnership interests (including both its general partner interests and any
Units it owns) and receiving the same value of those interests as Investors.
Additionally, the Company intends to profit from purchasing the Partnership's
Property Interests through a return on capital used to purchase those oil and
gas assets and invest in their development.  By purchasing the Partnership's
Property Interests itself, the Managing General Partner will be able to
maintain its position as operator of certain properties in which the
Partnership owns an interest.  Consequently, the Managing General Partner would
continue to receive operating fees as operator of those properties.  The sale
of the Partnership's Property Interests to the Managing General Partner will
have no effect or an inconsequential effect on the Managing General Partner's
net book value and net earnings.  However, the purchase of all of the oil and
gas assets of the Partnerships would increase the Company's proved reserves,
cash flow and total assets by a significant amount.  Lastly, if individual
Investors which approve the Proposal elect to purchase Company Common Stock,
rather than receiving cash upon liquidation of the Partnership, the Company
will benefit by using stock to pay the purchase price, rather than using its
available cash resources or borrowing facilities.
    

See "Special Factors--Managing General Partner Benefits" in the Joint Proxy
Statement/Prospectus.

SIMULTANEOUS PROPOSALS TO COMPANION PARTNERSHIPS

   
         Simultaneous Proposals are being made to investors in the
Partnership's Companion Partnership.  If both the Partnership and its Companion
Partnership do not approve their respective Proposals, it is likely to affect
the ability of the Partnership to consummate the sale of its Property
Interests.  Although the Investors in the Partnership may desire to sell their
Property Interests, the separation of the working interest and the
non-operating interests in the same properties may affect the salability of
those interests on a permanent basis.  If, for example, the Partnership
approves the Proposal but the Companion Partnership does not, the value of a
working interest burdened by a large non- operating interest is likely to be
lowered significantly.  [VARIABLE REVERSAL:  If, for example, the Partnership
approves the Proposal but the Companion Partnership does not, the value of a
non-operating interest is likely to be negatively affected by the lack of
control over operations.]  If the Partnership's Companion Partnership does not
    





                                       18
<PAGE>   284
approve its Proposal, then the Managing General Partner will advise the
Investors in the Partnership.  If the investors in the Partnership's Companion
Partnership do not vote in favor of its Proposal, then it is likely that the
Partnership will continue  operations and will produce its reserves until
depletion, with steadily decreasing rates of cash flow, and consequently
steadily decreasing amounts of cash distributions to the Investors.

                             VOTING ON THE PROPOSAL

   
         The Joint Proxy Statement/Prospectus and the Form of Proxy enclosed
with this Supplement are being provided for use at the Special Meeting of
Investors of the Partnership and at any adjournment or postponement of such
meeting (the "Meeting") to be held at 16825 Northchase Drive, Houston, Texas at
4:00 p.m. Central Time on _________, ____________, 1998.  The Meeting is being
called for the purpose of considering and voting upon the Proposal to
ultimately sell all of the oil and gas assets of the Partnership to the
Company, and to dissolve, wind up and terminate the Partnership and to transact
such other business as may be properly presented at the Special Meeting or any
adjournments or postponements thereof, all in accordance with the terms and
provisions of the Partnership's limited partnership agreement (the "Partnership
Agreement"), and the Texas Revised Limited Partnership Act (the "Texas Act").
This Joint Proxy Statement/Prospectus and enclosed Form of Proxy are first
being mailed to Investors on or about ____________, 1998.
    

   
          Pursuant to the terms of the Partnership Agreement, the Partnership,
if not terminated earlier, will continue in being through January 1, 2021, at
which point it will terminate automatically.
    

   
         Under the Partnership Agreement, the Proposal must be approved by the
affirmative vote of Investors holding 51% or more of the Units in the
Partnership as of the Record Date (defined below).  Therefore, an abstention by
an Investor will have the same effect as a vote against the Proposal.  The
solicitations are being made for votes in favor of the Proposal (which will
result in liquidation and dissolution of the Partnership).  As of the Record
Date, 75,781 Units were outstanding and held by record holders (excluding Units
held by the Managing General Partner as discussed below).  Accordingly, the
affirmative vote of holders of at least 38,648 Units is required to approve the
Proposal.   Each Investor appearing on the records of the Partnership as of
______, 1998 (the "Record Date") is entitled to notice of the Meeting and is
entitled to one vote for each  Unit held by such Investor.  VJM Corporation, a
California corporation, is the Special General Partner of the Partnership, and
owns a 1.5% interest in the Partnership as a general partner, but owns no
Units.  The Managing General Partner owns a general partner interest in the
Partnership of 13.5%.  Additionally, the Managing General Partner owns 7,514
outstanding Units in the Partnership, which ownership results from the Managing
General Partner's purchase over the life of the Partnership of Units from
Investors under the right of presentment, contained in the Partnership
Agreement.  Under the Partnership Agreement, the Managing General Partner may
not vote any Units owned by it for matters such as the Proposal.  The Managing
General Partner's non-vote, in contrast to abstention by Investors, will not
affect the outcome, because for purposes of adopting the Proposal, its Units
are excluded from the total number of voting Units.
    

VOTE REQUIRED

         The actual proxy to be used to register the vote on the Proposal
before you is the separate green sheet of paper included with this Supplement
and Joint Proxy Statement/Prospectus.  PLEASE USE THE GREEN PROXY TO CAST YOUR
VOTE ON THE PROPOSAL.

<PAGE>   285
                                        

         If a proxy is properly signed and is not revoked by an Investor, the
Units it represents will be voted in accordance with the instructions of the
Investor.  If no specific instructions are given, the Units will be voted FOR
the Proposal.  An Investor may revoke his proxy at any time before it is voted
at the Meeting.  Any Investor who attends the Meeting and wishes to vote in
person may revoke his proxy at that time.  Otherwise, an Investor 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.

SOLICITATION

   
         The solicitation is being made by the Partnership.  The Partnership
will bear the costs of the preparation of the Joint Proxy Statement/Prospectus
and of the solicitation of proxies and such costs will be allocated 85% to the
Investors and 15% to the general partners pursuant to the terms of the
Partnership Agreement.  As the Managing General Partner holds approximately
9.11% of the Units held by all Investors, 9.11% of the costs borne by the
Investors will be borne by the Managing General Partner, in addition to the
portion of the Partnership's total costs borne by the general partners by
virtue of their interest in the Partnership as general partners.  Solicitations
will be made primarily by mail.  In addition, a number of regular or temporary
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 Investors to encourage the return of proxies, although it does not
anticipate doing so.
    

                  PARTNERSHIP BUSINESS AND FINANCIAL CONDITION

   
         The Partnership is a Texas limited partnership formed June 30, 1989.  
Units in the Partnership are registered under Section 12(g) of the Securities
Exchange Act of 1934. The Partnership owns Property Interests in producing oil
and gas properties within the continental United States in which the Companion
Partnership also managed by the Managing General Partner owns the non-operating
interests.  By the end of October 1989, the Partnership had expended all of its
original capital contributions for the purchase of Property Interests in oil and
gas producing properties.  During 1997, approximately 48% of the Partnership's
revenue was attributable to natural gas production.  The Partnership has, from
time to time, performed workovers and recompletions on wells in which the
Partnership has Property Interests, using funds advanced by the Managing General
Partner or third parties to perform these operations, which amounts have been
subsequently repaid.  For information about the business of the Partnership, see
the attached Annual Report on Form 10-K for the year ended December 31, 1997 and
Quarterly Report on Form 10-Q for the quarter ended June 30, 1998.
    

   
         Investors made contributions of $8,329,500 in the aggregate to the
Partnership, the net proceeds of which has all been invested.  The Managing
General Partner has made capital contributions with respect to its general
partner interest of $70,596.  Additionally, pursuant to the presentment right
set forth in the Partnership Agreement, it has purchased 7,514 Units from
Investors.  From inception through July 31, 1998, the Partnership has made net
cash distributions to its Investors totaling $8,878,300.  Details of the
amounts of cash distributions made to partners over the past three years and
nine months are set out under "Cash Distributions" below.  Through July 31,
1998, the Managing General Partner has received net cash distributions from the
Partnership of $1,139,613 with respect to its general partner interest, and
$243,617
    





                                       20
<PAGE>   286
   
related to its limited partner interest.  On a per Unit basis, Investors had
received, as of July 31, 1998, $106.59 per $100 Unit, or approximately 106.6%
of their initial capital contributions.
    

   
         At the time that the Partnership's Property Interests covering
producing properties were acquired, prices averaged about $16.73 per barrel of
oil and $1.74 per Mcf of natural gas.  The majority of the Partnership's
Property Interests were acquired by the end of October 1989 when current prices
were predicted to escalate according to certain parameters from then current
levels to approximately $25.39 per barrel of oil and $3.05 per Mcf of natural
gas during 1997.  Generally prices did not escalate at the rate anticipated.
Most of the Partnership's reserves were produced from 1990 to 1994, during
which time the oil prices received by the Partnership for its production in
fact averaged $17.45 per barrel and the prices for natural gas averaged
approximately $1.79 per Mcf.  A comparison of oil and gas prices as described
in this paragraph appears in the graph presented below.
    

         The following graphs illustrate the effect on Partnership performance
of the variance between oil and gas prices projected at the time of acquisition
of the Partnership's Property Interests and actual oil and gas prices received
for production (as illustrated in the second graph) during the Partnership's
existence.

<PAGE>   289
         Lower prices also have 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.

CASH DISTRIBUTIONS

   
         Cash distributions are made to the partners in the Partnership on a
quarterly basis.  During the past three years and the first nine months of
1998, aggregate cash distributions made to all partners in the Partnership
(including the Managing General Partner) and the cash distributions per Unit
made to the Investors were:

TRANSACTIONS BETWEEN THE MANAGING GENERAL PARTNER AND THE PARTNERSHIP

   
    
   
         Under the Partnership Agreement, the Managing General Partner has
received certain compensation for its services and reimbursement for
expenditures made on behalf of the Partnership, which was paid at closing of
the offering of Units, in addition to revenues distributable to the Managing
General Partner with respect to its general partner interest or with respect to
Units it has purchased under the Investors' right of presentment.  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
                 $208,238, internal acquisition costs reimbursements of
                 $353,837 and formation costs reimbursements of $166,590 from
                 the Partnership from inception through December 31, 1997, none
                 of which has been received during the two years ended December
                 31, 1997.

   
         o       The Managing General Partner receives operating fees for wells
                 in which the Partnership has Property Interests and for which
                 the Managing General Partner or its affiliates serve as
                 operator.  During the years ended December 31, 1997 and
                 December 31, 1996 the aggregate operating fees paid to the
                 Company as operator by the Partnership were $37,716 and
                 $39,208, respectively.  Monthly operating fees range from $200
                 to $1,100 per well on an 8/8th's basis (i.e., the total amount
                 of operating fees paid by all interest owners in the well).
                 If the Property Interests are sold to the Managing General
                 Partner, there should be no change in its status as operator
                 for a number of the wells in which the Partnership has a
                 Property Interest.  The Managing General Partner believes that
                 it will be positively

                 affected, on the other hand, by liquidation of the
                 Partnership, both on the basis of its ownership interest in
                 the Partnership and for other reasons set out under "Special
                 Factors--Managing General Partner Benefits" in this
                 Supplement.

         o       The Managing General Partner is entitled to be reimbursed 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
                 Investors' original capital contributions to the Partnership
                 relative to investor contributions to all public partnerships
                 formed to purchase interests in producing properties for which
                 the Managing General Partner serves in that capacity.  Through
                 December 31, 1997, the Managing General Partner had received
                 $1,093,481 in the general and administrative overhead
                 allowance from the Partnership, of which $124,942 and $124,943
                 has been reimbursed during the years ended December 31, 1997
                 and December 31, 1996, respectively.

         o       The Managing General Partner has been reimbursed $42,650 in
                 direct expenses by the Partnership, all of which was billed
                 by, and then paid directly to, third party vendors, of which
                 $3,070 and $4,107 has been reimbursed during the years ended
                 December 31, 1997 and December 31, 1996, respectively.

NO TRADING MARKET

   
         There is no trading market for the Units, and none is expected to
develop, as described above under "Special Factors--Fairness of Proposed Sale
of Assets to the Managing General Partner as Compared to Continuing
Operations." Under the Partnership Agreement, Investors 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 the Partnership
Agreement.  Originally 661 Investors invested in the Partnership.  As of
__________, 1998, there were 626 Investors (excluding the Managing General
Partner).  The number of Units in the Partnership issued and outstanding at
that date was 83,295.  Through December 31, 1997, the Managing General Partner
had purchased 7,514 Units from Investors pursuant to the right of presentment.
The Managing General Partner does not have an obligation to repurchase Investor
interests pursuant to this right of presentment, but merely an option to do so
when such interests are presented for repurchase.
    

PRINCIPAL HOLDERS OF INVESTOR UNITS

         The Managing General Partner holds 9.11% of all outstanding Units of
the Partnership, resulting from the purchase of Units from Investors under
their right of presentment.  To the knowledge of the Managing General Partner,
there is one other holder of Units that holds more than 5% of the Units,
representing approximately 14.5% of the total Units outstanding.

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.

   
    
                   SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES

GENERAL

   
         The following briefly summarizes the federal income tax consequences
set forth under "Federal Income Tax Consequences of Adoption of the
Proposals"in the Joint Proxy Statement/Prospectus.   Statements of legal
conclusions herein regarding tax consequences are based upon an opinion of
Hoops & Levy, L.L.P., Special Tax Counsel, 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 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 Investors.
    

   
         A MORE COMPLETE SUMMARY OF THE FEDERAL INCOME TAX CONSEQUENCES TO
INVESTORS MAY BE FOUND IN THE REGISTRATION STATEMENT IN "FEDERAL INCOME TAX
CONSEQUENCES OF ADOPTION OF THE PROPOSALS." THIS SUMMARY DOES NOT DESCRIBE ALL
THE TAX ASPECTS WHICH MAY AFFECT INVESTORS NOR IS IT A COMPLETE DESCRIPTION OF
THE TAX ASPECTS IT DOES DESCRIBE.  It is generally directed to individual
Investors who are the original purchasers of the Units and hold interests in
the Partnership as "capital assets" (generally, property held for investment).
Each Investor that is a corporation, trust, estate, tax exempt entity, or other
partnership 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.
    

         TAXABLE GAIN OR LOSS UPON SALE OF PROPERTIES

   
         Investors will realize and recognize gain or loss, or a combination of
both, upon the Partnership's sale of its properties prior to liquidation.  It
is projected, however, that Investors will realize a net taxable gain upon the
sale of the Partnership properties.  Notwithstanding the foregoing, Investors
are not expected to realize any gain or loss upon the sale of properties the
Partnership receives from its Companion Partnership and sells to the Managing
General Partners.  Because the oil and gas properties, and related assets,
owned by the Partnership are properties used in a trade or business, the
character of gains and losses realized by the Investors generally will be
governed by Section 1231 of the Code.  Realized gains and losses generally must
be recognized and reported in the year the sale occurs. Each Investor's
recognized allocable share of the net Partnership 1231 gains or losses must be
netted with that Investor's individual section 1231 gains and losses recognized
during the year in order to determine the character of such net gains or net
losses under section 1231.  Net gains will be treated as capital gains except
to the extent recharacterized as ordinary income due to recapture and net
losses will be treated as ordinary losses.

<PAGE>   292
         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 an Investor in liquidation is less than such Investor's adjusted
tax basis in his Partnership interest, the Investor will realize and recognize
a capital loss to the extent of the excess.  If the amount of cash distributed
is greater than such Investor's adjusted tax basis in his Partnership interest,
the Investor will recognize a capital gain to the extent of the excess.
Because each Investor 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 Investors will be less than
such Investors' bases in their Partnership interests and thus will generate
capital losses.
    

         CAPITAL GAIN TAX

         Net long-term capital gains of individuals, trusts and estates
generally will be taxed at a maximum rate of 20%, while ordinary income,
including income from the recapture of intangible drilling and development
costs, depreciation and depletion, will be taxed at a maximum rate depending on
that Investor's taxable income of 36% or 39.6%.


         PASSIVE LOSS LIMITATIONS

         Investors 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.

         An Investor'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.

   
         THE FOREGOING DISCUSSION IS A SUMMARY OF THE INCOME TAX  CONSEQUENCES
SET FORTH UNDER "FEDERAL INCOME TAX CONSEQUENCES OF ADOPTION OF THE PROPOSALS"
IN THE JOINT PROXY STATEMENT/PROSPECTUS.  IT IS NOT INTENDED AS AN ALTERNATIVE
FOR INDIVIDUAL TAX PLANNING.  EACH INVESTOR SHOULD CONSULT HIS, HER OR ITS OWN
TAX ADVISOR CONCERNING THE PARTICULAR FEDERAL, STATE, LOCAL, FOREIGN AND OTHER
TAX CONSEQUENCES APPLICABLE TO HIM, HER OR IT OF THE SALE OF PROPERTIES AND THE
LIQUIDATION OF THE PARTNERSHIP.

OFFER OF SWIFT COMMON STOCK
    

         Investor Election to Purchase Shares

   
         In connection with the concurrent Proposals for sale of all of the oil
and gas assets of 63 Partnerships to the Company and the subsequent termination
of such Partnerships, the Company is offering up to 2,500,000 shares of the
Company's Common Stock.  Upon approval of the Proposals by the Partnership and
its Companion Partnership and sale of the Partnership's oil and gas assets, the
Partnership's assets will consist solely of cash which each investor as an
Eligible Purchaser of the Partnership will be entitled to receive as a
distribution.  The Company hereby offers to each such Eligible Purchaser the
opportunity to purchase shares of Common Stock with all or any portion of the
cash distribution such Eligible Purchaser will be entitled to receive, provided
that a minimum round lot of 100 shares must be purchased.  If an Eligible
Purchaser has interests in more than one Partnership, the cash distributions he
will be entitled to receive may be aggregated to meet the minimum round lot of
100 shares requirement.  Each such Eligible Purchase may purchase shares of
Common Stock with funds in addition to their cash distributions in order to
purchase (i) the minimum round lot of 100 shares, or (ii) shares in addition to
the number of shares for which their cash distribution will be applied, subject
to prorata limitations in the event of oversubscription.  No fractional shares
will be sold.

Attn: Special Transactions Committee   FAIR MARKET VALUE ESTIMATE
      Board of Directors               SWIFT ENERGY INCOME PARTNERS 1989-B, LTD.
                                       97-003-133


Gentlemen:

At your request, we have audited the proved, probable and possible reserves and
future net cash flow as of December 31, 1997, prepared by Swift Energy Company
("Swift") for certain interests owned by the partners in Swift Energy Income
Partners 1989-B, Ltd. This audit has been conducted according to the Standards
Pertaining to the Estimating and Auditing of Oil and Gas Reserve Information
approved by the Board of Directors of the Society of Petroleum Engineers on
October 30, 1979. We have reviewed these properties and where we disagreed with
the Swift reserve estimates, Swift revised its estimates to be in agreement.

From this audit, and in consultation with J.R. Butler and Company, our estimate
of the fair market value of this partnership is $3,083,309.

Fair market value as used herein is defined as that price that a willing buyer
will pay and a willing seller will accept at a given point in time, with neither
the buyer nor the seller under any compulsion to buy or sell, and both having
reasonable knowledge of all the material circumstances.

To estimate the fair market value attributable to the proved developed producing
reserves, the 10 percent discounted future net cash flow was multiplied by a
suitable factor (less than one) to account for the risk associated with the
reserves, operating expenses, and prices and to approximate tax consequences.
The internal rate of return and payout time were computed for this quantity and
compared with those at which current acquisitions are completed. Suitable
adjustments are then made to correspond to these two financial indices. Proved
developed nonproducing, proved undeveloped, probable and possible reserves
require capital investments and must be treated appropriately. For these cases,
the capital is added to the discounted net cash flow, then multiplied by a
suitable risk factor and the capital then subtracted. This has the effect that
capital is spent with certainty and the operating cash income is burdened with
the risk. Internal rate of return and payout time is calculated for each
estimate to establish reasonableness based upon it the reserve category.

The estimated future net cash flow is that cash flow which will be realized from
the sale of the estimated net reserves after deduction of royalties, ad valorem
and production taxes, direct operating costs and capital expenditures, when
applicable. Surface and well equipment salvage values and well plugging and
field abandonment costs have not been considered in the cash flow projections.
Future net cash flow as stated in this report is before the deduction of federal
income tax.

The following parameters are incorporated in the economic projections referenced
in this report. Initial oil prices are the existing prices on December 31, 1997,
and are escalated 3.5 percent per year beginning in 1999 through the year 2012
after adjusting for transportation and gravity variances. Initial natural gas
prices are those existing on December 31, 1997, and are escalated 3.5 percent
per year beginning in 1999 through the year 2012 after adjusting for
transportation and Btu content. Operating expenses are escalated at an annual
rate of 3.5 percent until the year 2012. The actual prices that will be received
and the associated costs may be more or less than those projected.

For those wells with sufficient production history, reserve estimates and rate
projections are based on the extrapolation of established performance trends.
Reserves for other producing and nonproducing properties have been estimated
from volumetric calculations and analogy with the performance of comparable
wells. The reserves referenced in this study are estimates only and should not
be construed as exact quantities. Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available. The proved reserves are
estimated in accordance with the definitions included in the Securities and
Exchange Commission Regulation S-X, Rule 4-10(a) except for the price and cost
escalations. The definitions are included in part as Attachment I. The probable
and possible reserves conform to the definitions approved by the Society of
Petroleum Engineers, Inc. The definitions are included as Attachment II.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented. The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December. Interim production to December 31, 1997, has been
estimated. Operating expenses as supplied by Swift were not audited, but were
reviewed for reasonableness. No independent well tests, property inspections or
audits of operating expenses were conducted by our staff in conjunction with
this study. We did not verify or determine the extent, character, obligations,
status or liabilities, if any, arising from any current or possible future
environmental liabilities that might be applicable.

In order to audit the reserves, costs and future cash flows referenced in this
report, we have relied in part on geological, engineering and economic data
furnished by our client. Although we have made a best efforts attempt to acquire
all pertinent data and to analyze it carefully with methods accepted by the
petroleum industry, there is no guarantee that the volumes of oil or gas or the
cash flows projected will be realized. The reserve and cash flow projections
referenced in this report may require revision as additional data become
available.

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                         PETROLEUM RESERVES DEFINITIONS
   SOCIETY OF PETROLEUM ENGINEERS (SPE) AND WORLD PETROLEUM CONGRESS (WPC)(1)

Reserves are those quantities of petroleum which are anticipated to be
commercially recovered from known accumulations from a given date forward. All
reserve estimates involve some degree of uncertainty. The uncertainty depends
chiefly on the amount of reliable geologic and engineering data available at the
time of the estimate and the interpretation of these data. The relative degree
of uncertainty may be conveyed by placing reserves into one of two principal
classifications, either proved or unproved. Unproved reserves are less certain
to be recovered than proved reserves and may be further sub-classified as
probable and possible reserves to denote progressively increasing uncertainty in
their recoverability.

The intent of the SPE and WPC in approving additional classifications beyond
proved reserves is to facilitate consistency among professionals using such
terms. In presenting these definitions, neither organization is recommending
public disclosure of reserves classified as unproved. Public disclosure of the
quantities classified as unproved reserves is left to the discretion of the
countries or companies involved.

Estimation of reserves is done under conditions of uncertainty. The method of
estimation is called deterministic if a single best estimate of reserves is made
based on known geological, engineering and economic data. The method of
estimation is called probabilistic when the known geological, engineering, and
economic data are used to generate a range of estimates and their associated
probabilities. Identifying reserves as proved, probable, and possible has been
the most frequent classification method and gives an indication of the
probability of recovery. Because of potential differences in uncertainty,
caution should be exercised when aggregating reserves of different
classifications.

Reserves estimates will generally be revised as additional geologic or
engineering data become available or as economic conditions change. Reserves do
not include quantities of petroleum being held in inventory, and may be reduced
for usage of processing losses if required for financial reporting.

Reserves may be attributed to either natural energy or improved recovery
methods. Improved recovery methods include all methods for supplementing natural
energy or altering natural forces in the reservoir to increase ultimate
recovery. Examples of such methods are pressure maintenance, cycling,
waterflooding, thermal methods, chemical flooding, and the use of miscible and
immiscible displacement fluids. Other improved recovery methods may be developed
in the future as petroleum technology continues to evolve.

PROVED RESERVES

Proved reserves are those quantities of petroleum which, by analysis of
geological and engineering data, can be estimated with reasonable certainty to
be commercially recoverable, from a given date forward, from known reservoirs
and under current economic conditions, operating methods, and government
regulations. Proved reserves can be categorized as developed or undeveloped.

If deterministic methods are used, the term reasonable certainty is intended to
express a high degree of confidence that the quantities will be recovered. If
probabilistic methods are used, there should be at least a 90% probability that
the quantities actually recovered will equal or exceed the estimate.

Establishment of current economic conditions should include relevant historical
petroleum prices and associated costs and may involve an averaging period that
is consistent with the purpose of the reserve estimate, appropriate contract
obligations, corporate procedures, and government regulations involved in
reporting these reserves.

In general, reserves are considered proved if the commercial producibility of
the reservoir is supported by actual production or formation tests. In this
context, the term proved refers to the actual quantities of petroleum reserves
and not just the productivity of the well or reservoir. In certain cases,
proved reserves may be assigned on the basis of well logs and/or core analysis
that indicate the subject reservoir is hydrocarbon bearing and is analogous to
reservoirs in the same area that are producing or have demonstrated the ability
to produce on formation tests.

The area of the reservoir considered as proved includes (1) the area delineated
by drilling and defined by fluid contacts, if any, and (2) the undrilled
portions of the reservoir that can reasonably be judged as commercially
productive on the basis of available geological and engineering data. In the
absence of data on fluid contacts, the lowest known occurrence of hydrocarbons
controls the proved limit unless otherwise indicated by definitive geological,
engineering or performance data.

<PAGE>   302

Reserves may be classified as proved if facilities to process and transport
those reserves to market are operational at the time of the estimate or there is
a reasonable expectation that such facilities will be installed. Reserves in
undeveloped locations may be classified as proved undeveloped provided (1) the
locations are direct offsets to wells that have indicated commercial production
in the objective formation, (2) it is reasonably certain such locations are
within the known proved productive limits of the objective formation, (3) the
locations conform to existing well spacing regulations where applicable, and (4)
it is reasonably certain the locations will be developed. Reserves from other
locations are categorized as proved undeveloped only where interpretations of
geological and engineering data from wells indicate with reasonable certainty
that the objective formation is laterally continuous and contains commercially
recoverable petroleum at locations beyond direct offsets.

Reserve which are to be produced through the application of established improved
recovery methods are included in the proved classification when (1) successful
testing by a pilot project or favorable response of an installed program in the
same or an analogous reservoir with similar rock and fluid properties provides
support for the analysis on which the project was based, and, (2) it is
reasonably certain that project will proceed. Reserves to be recovered by
improved recovery methods that have yet to be established through commercially
successful applications are included in the proved classification only (1) after
a favorable production response from the subject reservoir from either (a) a
representative pilot or (b) an installed program where the response provides
support for the analysis on which the project is based and (2) it is reasonably
certain the project will proceed.

UNPROVED RESERVES

Unproved reserves are based on geologic and/or engineering data similar to that
used in estimates of proved reserves; but technical, contractual, economic, or
regulatory uncertainties preclude such reserves being classified as proved.
Unproved reserves may be further classified as probable reserves and possible
reserves.

Unproved reserves may be estimated assuming future economic conditions different
from those prevailing at the time of the estimate. The effect of possible future
improvements in economic conditions and technological developments can be
expressed by allocating appropriate quantities of reserves to the probable and
possible classifications.

PROBABLE RESERVES

Probable reserves are those unproved reserves which analysis of geological and
engineering data suggests are more likely than not to be recoverable. In this
context, when probabilistic methods are used, there should be a least a 50%
probability that the quantities actually recovered will equal or exceed the sum
of estimated proved plus probable reserves.

In general, probable reserves may include (1) reserves anticipated to be proved
by normal step-out drilling where subsurface control is inadequate to classify
these reserves as proved, (2) reserves in formations that appear to be
productive based on well log characteristics but lack core data or definitive
tests and which are not analogous to producing or proved reservoirs in the area,
(3) incremental reserves attributable to infill drilling that could have been
classified as proved if closer statutory spacing had been approved at the time
of the estimate, (4) reserves attributable to improved recovery methods that
have been established by repeated commercially successful applications when (a)
a project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir characteristics appear favorable for commercial application, (5)
reserves in an area of the formation that appears to be separated from the
proved area by faulting and the geologic interpretation indicates the subject
area is structurally higher than the proved area, (6) reserves attributable to a
future workover, treatment, re-treatment, change of equipment, or other
mechanical procedures, where such procedure has not been proved successful in
wells which exhibit similar behavior in analogous reservoirs, and (7) 
incremental reserves in proved reservoirs where an alternative interpretation of
performance or volumetric data indicates more reserves than can be classified as
proved.

POSSIBLE RESERVES

Possible reserves are those unproved reserves which analysis of geological and
engineering data suggests are less likely to be recoverable than probable
reserves. In this context, when probabilistic methods are used, there should be
a least a 10% probability that the quantities actually recovered will equal or
exceed the sum of estimated proved plus probable plus possible reserves.

In general, possible reserves may include (1) reserves which, based on
geological interpretations, could possibly exist beyond areas classified as
probable, (2) reserves in formations that appear to be petroleum bearing based
on log and core analysis but may not be productive at commercial rates, (3)
incremental reserves attributed to infill drilling that are subject to technical
uncertainty, (4) reserves attributed to improved recovery methods when (a) a
project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir

<PAGE>   303

characteristics are such that a reasonable doubt exists that the project will be
commercial, and (5) reserves in an area of the formation that appears to be
separated from the proved area by faulting and geological interpretation
indicates the subject area is structurally lower than the proved area.

RESERVE STATUS CATEGORIES

Reserve status categories define the development and producing status of wells
and reservoirs.

     DEVELOPED: Developed reserves are expected to be recovered from existing
     wells including reserves behind pipe. Improved recovery reserves are
     considered developed only after the necessary equipment has been installed,
     or when the costs to do so are relatively minor. Developed reserves may be
     sub-categorized as producing or non-producing.

         PRODUCING: Reserves subcategorized as producing are expected to be
         recovered from completion intervals which are open and producing at the
         time of the estimate. Improved recovery reserves are considered
         producing only after the improved recovery project is in operation.

         NON-PRODUCING. Reserves subcategorized as non-producing include shut-in
         and behind-pipe reserves. Shut-in reserves are expected to be recovered
         from (1) completion intervals which are open at the time of the
         estimate but which have not started producing, (2) wells which were
         shut-in for market conditions or pipeline connections (3) wells not
         capable of production for mechanical reasons. Behind-pipe reserves are
         expected to be recovered from zones in existing wells, which will
         require additional completion work or future recompletion prior to the
         start of production.

     UNDEVELOPED RESERVES: Undeveloped reserves are expected to be recovered:
     (1) from new wells on undrilled acreage, (2) from deepening existing wells
     to a different reservoir, or (3) where a relatively large expenditure is
     required to (a) recomplete an existing well or (b) install production or
     transportation facilities for primary or improved recovery projects.

ATTENTION:       SPECIAL TRANSACTIONS COMMITTEE
                 SWIFT ENERGY COMPANY BOARD OF DIRECTORS

At the request of SWIFT ENERGY COMPANY (SWIFT), J. R. BUTLER AND COMPANY
(JRBCO) has conducted an evaluation audit of the hydrocarbon reserves and
future net cash flow as of December 31, 1997, associated with 44 Acquisition
Programs located in the U.S.A.  From this audit, and in consultation with H. J.
Gruy and Associates, Inc. (Gruy), JRBCO has generated its opinion of a "fair
market value" for these properties.  The market values of the properties were
distributed to various partnerships based on ownership to determine the fair
market value of each partnership. In JRBCO'S opinion, utilizing the
distribution of properties into the proper partnerships, the  estimated market
value of SWIFT ENERGY INCOME PARTNERS 1989-B, LTD. is $3,083,309.

Proved reserves in this instance are defined as those estimated volumes of
crude oil, condensate, natural gas, and natural gas liquids that geological and
engineering data demonstrate with reasonable certainty to be commercially
recoverable in the future from known reservoirs under a reasonable price and
cost escalation scenario.  Probable reserves are the estimated quantities of
commercially recoverable hydrocarbons associated with known accumulations which
are based on engineering and geological data similar to those used in the
estimates of proved reserves but, for various reasons, these data lack the
certainty required to classify the reserves as proved.  Possible reserves are
the estimated quantities of commercially recoverable hydrocarbons associated
with known accumulations, which are based on engineering and geological data
which are less complete and less conclusive than the data used in estimates of
probable reserves.  In some cases, economic or regulatory uncertainties may
dictate a probable or possible classification.

Recovery of proved reserves is not without risk but, as generally considered in
the industry, the risk of recovering probable reserves is substantially greater
than that associated with proved categories.  Likewise, possible reserves are
less certain to be recovered than probable.

The reserves and future performance estimates were prepared utilizing standard
petroleum engineering methods.  For properties with sufficient production
history,





                                       1
<PAGE>   305
reserves estimates and rate projections were based primarily on extrapolation
of established performance trends and reconciled, whenever possible, with
volumetric and/or material balance calculations.  For the non-producing zones
and undeveloped locations, reserves were determined by a combination of
volumetric calculations and analogy.  Volumetrically determined reserves or
those determined by analogy are generally subject to greater qualifications
than reserves estimates supported by established production decline curves
and/or material balance calculations.  Determination and classification of
proved reserves were performed (with exception of the use of escalated prices
and costs) in accordance with Securities and Exchange Commission guidelines.
The definitions used also conform to those promulgated by the Society of
Petroleum Engineers (SPE) and the World Petroleum Congresses (WPC).

The reserves and resulting "value estimates" included  in this study are not
exact quantities.  Future conditions may affect the recovery of estimated
reserves, revenue and net cash flow, and all categories of reserves may be
subject to revision and/or reclassification as more performance and well data
become available.  Please note, the reserves estimates made by JRBCO were done
in conjuction with an evaluation audit and are not the result of in-depth field
studies.  In conducting this audit JRBCO reviewed approximately 65% of SWIFT'S
proved "PV 10  value" (SEC PV10 as of December 31, 1997) for the total 44
Acquisition Programs.

Basic evaluation data were obtained principally from SWIFT and public sources.
The production data available to JRBCO were generally through  August 1997.
Gas and liquid prices were year end (CY 1997) prices as used in SWIFT'S
December 31, 1997, SEC cash flow runs.

Estimates of drilling, completion and workover costs were based on information
supplied by SWIFT.  Operating costs were also based on data supplied by SWIFT
in their Lease Operating Statement which was reviewed by JRBCO.  Surface and
well equipment salvage values and well plugging and field abandonment costs
were not considered in the revenue projections.

The estimates of future net cash flow used in market value calculations are
those revenues which should be realized from the sale of the estimated reserves
after deduction of royalties, ad valorem and production taxes, direct operating
costs and required capital expenditures, when applicable.  Future net cash flow
as used in this evaluation is before the deduction of federal income tax.

Market value estimates were obtained by applying qualitative risk adjustments
considered appropriate for the various reserves categories and "profit factors"
(as applicable) against discounted future net cash flow values obtained from an
escalated cost and pricing scenario.  Prices, costs and investments were
escalated at 3.5%/year for 15 years.  Final market value estimates were derived
in conjunction and consultation with Gruy.

In the conduct of our review, we have not independently verified the accuracy
and completeness of information and data furnished by SWIFT with respect to
ownership interests, oil and gas production volumes and rates, historical costs
of operation and development, product prices, agreements relating to current
and future operations and sales of production and other information relative to
such things as timing or scheduling of drilling or recompletion operations.

Field inspections were not made in connection with the preparation of this
report.  Furthermore, no judgments were made relative to environmental or other
legal liabilities.

It should be recognized that any oil or gas reserves estimate or forecast of
production and income is a function of engineering and geological
interpretation and judgment.  Such estimates should, therefore, be accepted and
used with the understanding that technical data, economic criteria or
regulatory information obtained subsequent to a study may justify revisions
which could increase or decrease the original estimates of reserves and value.

Attention:        Special Transactions Committee
                  Swift Energy Company Board of Directors

Gentlemen:

Pursuant to that certain letter agreement dated February 27, 1998 (the
"Agreement") between the Special Transactions Committee (the "Committee") of the
Board of Directors of Swift Energy Company ("Swift" or the "Company") and CIBC
Oppenheimer Corp. ("CIBC Oppenheimer"), you have retained CIBC Oppenheimer to
prepare an independent financial analysis as to the estimated fair market value
(the "CIBC Oppenheimer Valuation") of various interests (the "Assets") in oil
and gas properties (the "Properties'), which Assets are owned by Swift Energy
Income Partners 1989-B Ltd. (the "Partnership") of which the Company is the
managing general partner ("General Partner"). CIBC Oppenheimer performed a
similar analysis for 62 other partnerships (the "Partnerships") of which the
Company is the General Partner. It is CIBC Oppenheimer's understanding that the
General Partner has proposed to purchase substantially all of the Partnership's
Assets and, in turn, dissolve and wind up the Partnership. It is also CIBC
Oppenheimer's understanding that the Committee has also retained the reserve
engineering firms of H.J. Gruy & Associates, Inc. and J.R. Butler & Company
(collectively, the "Engineering Consultants") to prepare a separate analysis as
to the estimated fair market value of the Assets (the "Engineering Consultants'
Valuation").

In arriving at the CIBC Oppenheimer Valuation, we, among other things:

         (i)      Reviewed the historical financial returns to the limited 
                  partners of the Partnership;

         (ii)     Held discussions with senior management of the Company as to 
                  the Partnership's operational and financial prospects;

         (iii)    Held discussions with senior management of the Company 
                  regarding the general characteristics of the Properties
                  underlying the Assets, including location, productive
                  geological formations, future development potential and oil
                  and gas marketing arrangements;

         (iv)     Held discussions with the Engineering Consultants regarding
                  the general characteristics of the Properties underlying the
                  Assets, including location, productive geological formations
                  and future development potential;

         (v)      Reviewed the reserve engineering reports supplied to us by the
                  Engineering Consultants and, particularly, reviewed the
                  estimated future net cash flow to be generated from the
                  production of proved reserves of the Properties underlying the
                  Assets discounted to present value using an annual discount
                  rate of 10% (the "PV-10 Value") dated as of December 31, 1997;
                  these amounts were 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 future
                  income tax expense or depreciation, depletion and
                  amortization;

         (vi)     Reviewed the Engineering Consultants' Valuation of the 
                  Properties underlying the Assets;

         (vii)    Reviewed historical operating and financial results of the
                  Properties underlying the Assets which included PV-10 Value,
                  proved reserves on a barrel of oil equivalent ("BOE") basis
                  and projected earnings before interest, taxes and
                  depreciation, depletion and amortization ("EBITDA") as
                  prepared by the Engineering Consultants and discussed with
                  senior management of the Company;

         (viii)   Reviewed and analyzed financial terms of similar transactions
                  in which public oil and gas companies liquidated partnerships
                  of which they were the general partner;

         (ix)     Reviewed and analyzed transactions involving the sale of oil
                  and gas companies we deemed comparable to the Partnership(s)
                  individually and collectively and to the Company;

         (x)      Reviewed and analyzed transactions involving the sale of oil 
                  and gas properties we deemed comparable to the Properties
                  underlying the Assets;

         (xi)     Reviewed financial and market data for certain public 
                  companies we deemed comparable to the Partnership(s)
                  individually and collectively and to the Company; and

         (xii)    Performed such other analyses and reviewed such other
                  information as we deemed appropriate.

In determining the CIBC Oppenheimer Valuation, we have relied upon and assumed,
without independent verification or investigation and at the direction of the
Committee, (i) the accuracy and completeness of all of the financial and other
information available to us from public sources or provided to us by the Company
and their representatives (including the Engineering Consultants), (ii) that the
reserve engineering reports supplied to us by the Engineering Consultants as
described in clause (v) above have been reasonably prepared and are based on
their best business judgment, (iii) that the information with respect to the
Partnership's ownership of the Assets, as provided to the Engineering
Consultants and to us was accurate in all respects, (iv) with respect to the
historical operating and financial results and projections provided to us as
described in clause and (vii) above, that such information and projections were
reasonably prepared and were based on the best currently available information,
estimates and good faith judgment of the Company's management and their
representatives (including the Engineering Consultants).

Not being experts in the geological evaluation of oil and gas reserves, we have,
with your consent, relied without independent verification upon the audit of the
reserve estimates prepared by the Engineering Consultants for the purpose of
estimating fair market value of the Assets. In addition, we have not made a
physical inspection of the Properties underlying the Assets, nor have we made
any independent evaluations, appraisals or inspections of the Company's or the
Partnership's other assets or the Company's or the Partnership's liabilities
(contingent or otherwise). We have not reviewed any relevant agreements which
may exist between the General Partner and the limited partners governing the
Partnership, nor have we considered the effect which the ownership structure of
the Partnership and the terms of the agreements of the Partnership may have upon
the fairness of the consideration offered by any general partner of the
Partnership. We have not reviewed the books and records of the Partnership and
have assumed, with your consent, that the Partnership's ownership interests in
the Properties underlying the Assets, as provided to us by you, is true and
correct.

The CIBC Oppenheimer Valuation is based upon analyses of the foregoing factors
in light of our assessment of general economic, financial, market and other
conditions and circumstances as of the date of this letter and any changes in
such conditions and circumstances may affect the validity or fairness of the
CIBC Oppenheimer Valuation. CIBC Oppenheimer disclaims any obligations to
update, revise or reaffirm the CIBC Oppenheimer Valuation. The CIBC Oppenheimer
Valuation reflects our estimate of the consideration that could have been
received by the Partnership in a sale of the Assets in an orderly manner in a
private market transaction in which neither buyer nor seller is under any
compunction to complete such transaction. The CIBC Oppenheimer Valuation falls
within a range of values which we believe, subject to the foregoing conditions,
represent possible fair market value estimates of the Partnership's interest in
the Assets. The CIBC Oppenheimer Valuation should not be viewed as a guarantee
of the price that a willing buyer might have paid for the Assets.

CIBC Oppenheimer, as part of its investment banking services, is regularly
engaged in the valuation of businesses and securities in connection with
mergers, acquisitions, underwritings, sales and distributions of listed and
unlisted securities and private placements. CIBC Oppenheimer has provided
certain investment banking and financial advisory services to the Company from
time to time, including acting as co-manager of the Company's Convertible
Subordinated Notes financing in November 1996 and lead manager of the public
offering of the Company's Common Stock in July 1995, and may be involved in
future investment banking activities on behalf of the Company. CIBC Oppenheimer
will also receive a fee upon delivery of this CIBC Oppenheimer Valuation. In the
ordinary course of business, CIBC Oppenheimer actively trades in the equity
securities of the Company for CIBC Oppenheimer's own account and for the
accounts of CIBC Oppenheimer's customers and, accordingly, may at any time hold
a long or short position in such securities.

Based upon and subject to the foregoing, and based upon such other matters as we
consider relevant, it is CIBC Oppenheimer's estimate that the value of Swift
Energy Income Partners 1989-B Ltd. interest in the Assets as of the date hereof
is $3,028,036.

This letter is being provided for the use of the Committee in its evaluation of
a possible proposal that the Partnership sell the Assets to the Managing General
Partner and dissolve and wind up its affairs. This letter is not intended to
confer rights or remedies upon any stockholder of the Company or any partner of
the Partnership and may not be relied upon by any person or entity other than
the Committee. Neither this letter nor the CIBC Oppenheimer Valuation may be
published or otherwise used or referred to, in whole or

part, nor shall any public reference to CIBC Oppenheimer, this letter or the
CIBC Oppenheimer Valuation be made without the prior written consent of CIBC
Oppenheimer; provided, however, that the Company and the Partnership may include
a copy of this letter and a reference to CIBC Oppenheimer in the proxy statement
to be distributed to limited partners of the Partnership in connection with the
solicitation of the approval of the proposal that the Partnership sell the
Assets to the General Partner and dissolve and wind up its affairs. Neither this
letter nor the CIBC Oppenheimer Valuation constitutes a recommendation to any
partner of the Partnership as to how such partner should vote on or respond to
the proposal that the Partnership sell the Assets to the General Partner and
dissolve and wind up its affairs.

Sincerely yours,

                                             97-003-133

Gentlemen:

At your request, we have made an audit of the reserves and future net cash flow
as of December 31, 1997, prepared by Swift Energy Company ("Swift") for certain
interests in Swift Energy Income Partners 1989-B. This audit has been conducted
according to the standards pertaining to the estimating and auditing of oil and
gas reserve information approved by the Board of Directors of the Society of
Petroleum Engineers on October 30, 1979. We have reviewed these properties and
where we disagreed with the Swift reserve estimates, Swift revised its estimates
to be in agreement. The estimated net reserves, future net cash flow and
discounted future net cash flow are summarized by reserve category in Table 1
for both the 100% Fund Level Partnership and the Limited Partnership Interest.

The discounted future net cash flow is not represented to be the fair market
value of these reserves and the estimated reserves included in this report have
not been adjusted for risk.

The estimated future net cash flow shown is that cash flow which will be
realized from the sale of the estimated net reserves after deduction of
royalties, ad valorem and production taxes, direct operating costs and required
capital expenditures, when applicable. Surface and well equipment salvage values
and well plugging and field abandonment costs have not been considered in the
cash flow projections. Future net cash flow as stated in this report is before
the deduction of state and federal income tax.

In the economic projections, prices, operating costs and development costs
remain constant for the projected life of each lease.

The reserves included in this study are estimates only and should not be
construed as exact quantities. Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available. Proved reserves are
estimated in accordance with the definitions contained in Securities and
Exchange Commission Regulation S-X, Rule 4-10 (a). The definitions are included
in part as Attachment I.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented. The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December. Interim production to December 31, 1997, has been
estimated. No independent well tests, property inspections or audits of
operating expenses were conducted by our staff in conjunction with this study.
We did not verify or determine the extent, character, obligations, status or
liabilities, if any, arising from any current or possible future environmental
liabilities that might be applicable.

Swift Energy Company                  -2-                      February 10, 1998

In order to audit the reserves, costs and future net cash flows shown in this
report, we have relied in part on geological, engineering and economic data
furnished by our client. Although we have made a best efforts attempt to acquire
all pertinent data and to analyze it carefully with methods accepted by the
petroleum industry, there is no guarantee that the volumes of oil or gas or the
cash flows projected will be realized.

Production rates may be subject to regulation and contract provisions, and may
fluctuate according to market demand or other factors beyond the control of the
operator. The reserve and cash flow projections presented in this report may
require revision as additional data become available.

We are unrelated to Swift and we have no interest in the properties included in
the information reviewed by us. In particular:

         1.     We do not own a financial interest in Swift or its oil and gas 
                properties.

         2.     Our fee is not contingent on the outcome of our work or report.

         3.     We have not performed other services for or have any other
                relationship with Swift that would affect our independence.

If investments or business decisions are to be made in reliance on these
estimates by anyone other than our client, such person with the approval of our
client is invited to visit our offices at his expense so that he can evaluate
the assumptions made and the completeness and extent of the data available on
which our estimates are based.

Any distribution or publication of this report or any part thereof must include
this letter in its entirety.

                                Yours very truly,

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                                   SUPPLEMENT
                                       TO
                        JOINT PROXY STATEMENT/PROSPECTUS
                              DATED ________, 1998
                      SPECIAL MEETINGS OF THE PARTNERSHIPS
                                      AND
                          OFFERING OF COMMON STOCK OF
                              SWIFT ENERGY COMPANY



         For the definition of capitalized terms herein which are not otherwise
defined, see "Glossary" in the Joint Proxy Statement/Prospectus.  Other
discussions which are cross-referenced in this Supplement are contained in the
Joint Proxy Statement/Prospectus, unless otherwise noted.

         Swift Energy Company ("Swift" or the "Company") is the Managing
General Partner ("Managing General Partner") of 63 Texas limited partnerships
(the "Partnerships"), including the Partnership, formed between 1986 and 1994
to invest in producing oil and gas properties.  Swift is asking interest
holders (referred to herein as "Investors") in the Partnership (and similarly
in the other 62 Partnerships) to approve a Proposal to ultimately sell all of
the Partnership's oil and gas assets to the Managing General Partner (the
"Proposal") for $1,427,367, which is a purchase price derived by choosing the
higher of two estimates of fair market value of those assets determined by
three independent Appraisers, and adding to that higher number a 7.5% premium.

         If the Proposal is approved by Investors in the Partnership and its
Companion Partnership, after the ultimate sale of all of its oil and gas assets
the Partnership will dissolve, wind up and terminate.  The Partnership will
receive cash for its oil and gas assets, which in turn is to be distributed to
the Investors in the Partnership (along with the net of all assets less
liabilities of the Partnership) in accordance with their respective percentage
ownership interests in the Partnership.  If Investors in the Partnership
approve the Proposal, then each Investor can elect, in their sole individual
discretion, to receive shares of Common Stock of the Company (without payment
of any brokerage commissions) instead of some or all of the cash which they are
entitled to receive upon the Partnership's liquidation.

         The reasons for and effects of the Proposals may be different for
investors in each of the Partnerships.  This Supplement has been prepared to
highlight for the Investors in the Partnership the particular risks, effects
and fairness of the Proposal to the Investors in the Partnership and to provide
information on the Partnership to its Investors, in connection with the
solicitation of proxies by the
<PAGE>   318
Managing General Partner for use at the Special Meeting of the Investors in the
Partnership in voting upon the Proposal and to transact such other business as
may be properly presented at the Special Meeting or any adjournments or
postponements thereof.

         BOTH THE VOTE UPON THE PROPOSAL AND ANY ELECTION MADE BY AN INDIVIDUAL
INVESTOR TO RECEIVE SHARES OF SWIFT ENERGY COMPANY COMMON STOCK ARE SUBJECT TO
NUMEROUS RISK FACTORS, INCLUDING THOSE HIGHLIGHTED BELOW.  SEE "RISK FACTORS"
IN THIS SUPPLEMENT AND IN THE JOINT PROXY STATEMENT/PROSPECTUS FOR A FULL
DISCUSSION OF ALL RISK FACTORS.

o        Substantial conflicts of interest exist because if the Proposal is
         approved by the Partnership and its Companion Partnership, the
         Managing General Partner will purchase all of the oil and gas assets
         from the Partnership while it serves as its Managing General Partner.

o        The purchase price for the Partnership's Property Interests may not be
         the highest possible price.

o        No independent representative negotiated the terms of the purchase
         price with the Managing General Partner.

o        No fairness opinion was acquired regarding the fairness of the
         purchase price.

   
o        The Managing General Partner may profit from acquisition of the
         Partnership's oil and gas assets by investing capital in order to
         develop non-producing reserves of the acquired Property Interests and
         possibly through improvement in oil and gas prices.
    

   
o        Estimates of distributions to Investors from continuing operations of
         the Partnership for the life of its reserves are higher than amounts
         anticipated to be received if Investors vote in favor of the Proposal.
         See "Special Factors--Fairness of Proposal of Sale of Assets as
         Compared to Continuing Operations."
    

o        An election by an Investor to receive shares of Swift Common Stock in
         lieu of cash distributable to Investors subjects such Investors to the
         risks of investing in the Company.

                 This Supplement is dated ______________, 1998

                                THE PARTNERSHIP

   
         The Partnership was formed over five years ago and owns non-operating
Property Interests in producing oil and gas properties in six states in which
its companion partnership, Swift Energy Operating Partners 1993-B, Ltd.
("Companion Partnership"), formed at approximately the same time and also
managed by the Managing General Partner, owns the working interests. The
Partnership had expended all of its original capital contributions by the end
of October 1993.  A majority of the Partnership's oil and gas properties are
natural gas properties, representing approximately 60% of the Partnership's
1997 production and approximately 59% of its total proved reserves at December
31, 1997. From time to time, the Companion Partnership has performed workovers
and recompletions of wells in which the Partnership has non- operating
interests, using funds advanced by the Managing General Partner to perform
these operations, which amounts have been subsequently repaid.  The Partnership
owns interest in 245 wells in 25 fields.
    

   
         The following table presents information on those fields in which the
Partnership has Property Interests which constitute 10% or more of the
Partnership's PV-10 Value at December 31, 1997.  The Partnership's "PV-10
Value" is the estimated future net cash flows (using unescalated prices) from
production of proved reserves attributed to the Partnership's Property
Interests, discounted to present value at 10% per annum.  Attachment D to this
Supplement is the report dated February 10, 1998 of the audit by H.J. Gruy and
Associates, Inc., Independent Petroleum Consultants, of the oil and gas
reserves underlying the Partnership's Property Interests, and future net cash
flow expected from the production of those reserves as of December 31, 1997,
presented both for the Partnership as a whole and as to those reserves solely
attributable to the Investors in the Partnership.  This report has not been
updated to include the effect of production since year-end 1997.  In estimating
these reserves, the Managing General Partner, in accordance with criteria
prescribed by the Securities and Exchange Commission, has used year-end 1997
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.  The Managing General
Partner is not aware of any favorable or adverse event causing a significant
change in the estimated amount (as set forth in Attachment D hereto, which is
the report of H.J. Gruy and Associates, Inc.) of proved reserves of the
properties in which the Partnership owns an interest has occurred between
December 31, 1997 and the date of this Supplement.
    

   
         The information below includes the location of each field in which the
Partnership has an interest, the number of wells and operators, together with
information on the percentage of the Partnership's total PV-10 Value on
December 31, 1997 attributable to each of these fields.  Information is also
provided regarding the percentage of the Partnership's 1997 production (on a
volumetric basis) from each of these fields.  Of the remaining other fields in
which the Partnership owns a Property Interest, 13 of such fields each comprise
less than 1% of the Partnership's PV-10 Value at December 31, 1997, and the
PV-10 Value of each of the other ten fields averages less than 3% of the
Partnership's PV- 10 Value at the same date.

         The Partnership's total assets at year-end 1997 were $2,472,675 and
the PV-10 Value of its total proved reserves at the same date was $2,048,682.
Based upon the audit of the Partnership's Total Proved Reserves at year-end
1997, those reserves were comprised of the following three categories:

                                                                ====
</TABLE>

- --------------
       (1)Proved producing reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.

       (2)Behind-pipe reserves are proved reserves that will not contribute to
cash flows until recompletion projects have been implemented to place them into
production.  The impact of these recompletion projects will also be limited
until the costs of implementation have been recovered.  In general, it is not
appropriate to bring behind-pipe reserves into production until the formation
that is currently producing has been depleted.  Premature recompletions can
lead to permanent reductions in a well's proved reserves.

       (3)Non-developed reserves are reserves that are expected to be recovered
from new wells on undrilled acreage, or from existing wells where a relatively
major expenditure is required for recompletion.  Therefore, significant
additional expenditures are usually required before undeveloped reserves can be
produced.

         Attachment D is the annual reserves audit and independent reserves
report prepared by H.J. Gruy and Associates, Inc. as to the Partnership's
remaining proved oil and gas reserves available for production over a period in
excess of 15 years.  These quantities have been given a value based upon prices
for oil and gas at December 31, 1997.  The value is determined based upon the
assumption that these prices will remain in effect over the life of these
reserves.  This value is then discounted at 10% per year to arrive at





                                       4
<PAGE>   321
   
the value (in today's dollars) of these revenues ("PV-10 Value").  This PV-10
Value for the Partnership's Property Interests is $2,048,682.  It is also
estimated that $235,443 in future capital costs must be spent to develop the
Partnership's non-producing reserves.
    

                                  RISK FACTORS

   
o        Although the fair market value of the Property Interests proposed to
         be purchased from the Partnership by the Managing General Partner was
         based upon a determination by three independent Appraisers, no opinion
         was acquired as to the fairness of the ultimate purchase price, which
         was determined in the Managing General Partner's sole judgment by
         adding a 7.5% premium over the higher of the two fair market value
         estimates for the Partnership's Property Interests determined by the
         Appraisers.  Therefore, the purchase price was not determined on an
         impartial basis by a party not involved in the transaction, and
         another party intent upon purchasing the Property Interests in the
         Partnership might have offered a different purchase price.  There is
         no guarantee that the purchase price represents the highest possible
         price that could be received for the Partnership's Property Interests
         in all circumstances.  It is possible that a higher (or lower) price
         might be received if these assets were sold on another basis, such as
         at auction or in negotiated sales.  Furthermore, the assessment of the
         value of the Partnership's proved non-producing reserves could vary
         widely, given the typical discounting in valuing non-producing
         reserves.
    

   
o        The Managing General Partner did not retain an independent
         representative to act on behalf of the Investors in the Partnership in
         structuring and negotiating the terms or price of the Proposal or the
         purchase price.  The price at which it is proposed that the Company
         purchase the Property Interests from the Partnership has not been
         negotiated at arm's length and is subject to significant conflicts of
         interest between the Company acting as the purchaser of such
         properties while serving as the Managing General Partner of the
         Partnership.  If an independent representative had been retained for
         the Partnership, the terms or price might have been different and
         possibly more favorable to Investors.
    

   
o        The fair market value (excluding the 7.5% premium) established for the
         Partnership's Property Interests is based upon the Appraisers'
         evaluation of that value.  Year-end 1997 prices, along with other
         current market factors, were used as a starting point for the
         Appraisers' analysis, and prices and costs were then escalated at a
         rate of 3.5% per year over 15 years.  Substantial increases in the
         prices for oil and gas in the future might result in Investors
         receiving higher distributions from continued operations of the
         Partnership, although such distributions could be negatively affected
         by oil and gas decreases.
    

   
o        In order to effectuate the sale of its Property Interests, the
         Proposal must not only be approved by the Partnership, but a similar
         Proposal must be approved by the Companion Partnership.  This
         requirement exists because of the significant lowering of the value of
         either (i) a working interest burdened by a large non- operating
         interest controlled by a different party, or (ii) a non-operating
         interest in properties the operations of which are controlled by a
         third party.  Therefore, even if the Investors in the Partnership
         approve the Proposal to sell their Property Interests, this may not be
         done without the approval of a similar Proposal by investors in the
         Companion Partnership.  If either Partnership does not approve its
         Proposal, then the Managing General Partner will reassess  the value
         of the Property Interests of each Partnership and attempt to formulate
         a new proposal for the investors in each such Partnership.

<PAGE>   322
   
o        A majority of the Partnership's proved oil and gas reserves are
         non-producing.  Because non-producing reserves are traditionally
         discounted due to future costs which must be incurred to recover those
         reserves and the risk that any drilling will be unsuccessful, there is
         a risk that the discount applied to the non-producing reserves by the
         Petroleum Engineering Consultants could be greater than the discount
         applied by a third party purchaser.  Likewise, it is likely that any
         drilling conducted on Property Interests acquired from the Partnership
         has upside potential, the benefit of which will go to the Managing
         General Partner if it acquires those properties.
    


   
o        Investors that are subject to federal income tax on an investment in
         the Partnership are required to recognize gain or loss on the sale of
         oil and gas assets by the Partnership and the subsequent liquidation
         of the Partnership.  The character of the gain or loss depends on
         certain factors specific to individual Investors.  It is anticipated
         that Investors that acquired their interests in the original offering
         and that are subject to federal income tax will recognize a loss for
         federal income tax purposes.  Any tax that may be due must be paid
         even if such Investors choose to acquire Company Common Stock with
         some or all of their proceeds from property sales.  Investors also
         should consult their individual tax advisors to determine whether they
         are subject to any state tax.  For a broader discussion of the tax
         consequences, Investors should read "Federal Income Tax Consequences
         of Adoption of the Proposals" in the Joint Proxy Statement/Prospectus,
         and "Summary of Federal Income Tax Consequences" in this Supplement.
    

   
o        Investors that are Tax Exempt Plans that have directly or indirectly
         acquired their Partnership interests through debt financing, as
         defined in the Internal Revenue Code of 1986, as amended, may be
         subject to taxation on the Partnership's sale of property and the
         liquidation of the Partnership, while other Tax Exempt Plans are not
         expected to be subject to taxation on the sale and liquidation.  See
         "Summary of Federal Income Tax Consequences--Tax Treatment of Tax
         Exempt Plans--Debt-Financed Property" in this Supplement.  It is
         anticipated that Tax Exempt Plans that acquired their interests in the
         original offering and that are subject to federal income tax will
         recognize a loss for federal income tax purposes.
    

   
o        As currently proposed, Investors that subscribe for Company Common
         Stock pursuant to this Offering may not receive some or all of the
         cash which otherwise would be distributed to them as part of the
         liquidating distribution of their Partnership.  The amount of any cash
         liquidating distribution they actually receive depends upon the
         purchase price to be paid for any Company Common Stock they elect to
         and are entitled to receive pursuant to the terms of this Offering.
         For federal income tax purposes, Investors subscribing for shares of
         Company Common Stock will be treated as though they had purchased
         those shares for cash, even though they never had actual possession of
         the cash used to acquire the shares.  Additionally, the fact that such
         Investors elect to acquire Company Common Stock rather than receive
         cash in liquidation of their Partnership interests will not affect the
         federal income tax consequences attending the liquidation of their
         Partnership interests.  Because the purchase of shares of Company
         Common Stock will reduce the cash received by Investors upon the
         Partnership's liquidation, to the extent that Investors owe federal
         income tax as a result of the liquidation, they may not receive
         sufficient cash to pay some or all of any tax they may owe on the
         liquidation.  Such Investors owing tax as a result of the liquidation
         will have to pay such tax from sources other than any cash liquidating
         distribution from the Partnership.

                             CONFLICTS OF INTEREST

   
         There are substantial conflicts of interest which exist by virtue of
the Managing General Partner acting in that capacity on behalf of the
Partnership while at the same time acting as the proposed purchaser of all of
the oil and gas assets of the Partnership.  These conflicts of interest are
discussed below.
    

o        The terms of the Proposal are established by the Company which is also
         the Managing General Partner of the Partnership.

o        Neither the Managing General Partner nor a majority of its independent
         directors retained an independent representative to act on behalf of
         the Partnership's Investors for the purposes of negotiating the terms
         upon which any such sale to the Managing General Partner would be made
         or for the preparation of a report concerning the fairness of the
         entire transaction.

See "Summary--Conflicts of Interest" and "Conflicts of Interests" in the Joint
Proxy Statement/Prospectus.

                                SPECIAL FACTORS

BACKGROUND AND PURPOSE OF THE PROPOSAL

         A number of factors have led to the decision of the Company in its
capacity as Managing  General Partner to solicit approval of the Proposal by
Investors in the Partnership.  The general improvement in the prices for
natural gas over the last several years, relative to such prices in the
mid-1990's, make this an appropriate time to consider the Proposal to sell the
Partnership's Property Interests.  The structure being proposed, which involves
the sale of the Partnership's oil and gas assets to the Managing General
Partner, is being submitted for approval by Investors in an attempt to realize
the highest value for those assets.  For the reasons set out below, the
Managing General Partner believes that the Proposal is fair to Investors in the
Partnership, given that the purchase price for these assets has been determined
by taking the higher of two fair market value estimates by three independent
Appraisers and adding to it a 7.5% premium.

         Approval of the Proposal will have the following effects:

   
1.       The Managing General Partner will purchase all of the oil and gas
         assets of the Partnership, provided its Companion Partnership has
         approved its proposal.
    

   
2.       When the Partnership sells all of its oil and gas assets, it will be
         required to liquidate and distribute its remaining assets (principally
         the cash proceeds from the sale) to its partners (including the
         general partners) in accordance with their respective ownership
         interests in the Partnership.
    

3.       Investors will be given the option of electing to receive shares of
         Swift Common Stock, in amounts that they choose on an individual
         basis, in lieu of some or all of the cash they would be entitled to
         receive upon the Partnership's liquidation.





                                       7
<PAGE>   324
   
4.       The Managing General Partner may spend capital to develop
         non-producing reserves on properties which it acquires from the
         Partnership, although the properties in which such investment will be
         made have not yet been determined.
    

   
5.       Investors in the Partnership may be taxed on the sale of the
         Partnership's oil and gas assets, although such sale is expected to
         result in a taxable loss to Investors that acquired their interests in
         the original offering.
    

PROPOSED PURCHASE PRICE

   
         As discussed in greater detail below, the Petroleum Engineering
Consultants estimated that the aggregate fair market value of the Partnership's
Property Interests as of December 31, 1997 is $1,234,678.  CIBC Oppenheimer
estimated a fair market value of the same Property Interests at the same date
of $1,327,783.  The Special Transactions Committee chose the higher of these
two determinations as the" Fair Market Value" for the purchase of these
interests and the Board of Directors of the Company determined to pay a 7.5%
premium ($99,584) above the Fair Market Value to purchase the Partnership's
Property Interests, resulting in a purchase price of $1,427,367.  This compares
to the total purchase price for all of the oil and gas assets of all 63
Partnerships which are considering similar proposals of approximately $81
million.  The valuation estimates of the Appraisers are attached to this
Supplement and incorporated herein by reference as follows:  Attachment A is
the fair market value estimate of H.J. Gruy and Associates, Inc., Attachment B
is the fair market value estimate of J.R. Butler and Company, and Attachment C
is the fair market value estimate of CIBC Oppenheimer Corp.  The PV-10 Value
prepared on an annual basis by H.J. Gruy of the same Property Interests as of
the same date is $2,048,682.
    

REASONS FOR THE PROPOSAL

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

   
         Current Liquidating Distribution Lowers Volatility Risk.  The
Partnership has been in existence for over five years.  The Managing General
Partner believes that the ability to receive the estimated liquidating
distribution in one lump sum at this time, rather than in smaller amounts over
a longer period, is one of the benefits of the Proposal, without the risk of
such distributions being negatively affected by oil and gas price decreases and
the inherent risks associated with geological, engineering and operational
matters.  It is also the Managing General Partner's belief that improvements
over the last several years in the level of gas prices, relative to such prices
in the mid-1990s, makes this an appropriate time to consider the sale of the
Partnership's Property Interests and increases the likelihood of maximizing the
value of the Partnership's assets, although the future prices and market
volatility cannot be predicted with any accuracy.
    

   
         Decreasing Cash Flow While Expenses Continue.  The Partnership's
underlying interests in oil and gas reserves are expected to continue to
decline as remaining reserves are produced.  Declines in well production are
based principally upon the maturity of the wells, not on market factors.  These
declines will continue to occur while oil field overhead and operating costs
($47,299 in 1997) and direct and general and administrative expenses ($116,395
in 1997) continue, which are relatively fixed amounts.  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
    





                                       8
<PAGE>   325
compliance with the securities laws, producing reports to partners and filing
partnership tax returns, do not decline as revenues decline.  By accelerating
the liquidation of the Partnership, those future administrative costs will be
avoided by the Partnership.

   
         Undeveloped and Behind Pipe Reserves.  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 Property Interests, especially the precipitous
decline of gas prices in 1995.  Gas 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.  Reduced cash flow affected the ability of the Companion
Partnership to develop the significant undeveloped proved reserves in which the
Partnership has an interest.  Although at December 31, 1997, it was estimated
that approximately 44% of the ultimate recoverable reserves in which the
Partnership has a non-operating interest were still available for future
production, less than half (41%) of these available reserves were proved
producing reserves.  Of the non-producing reserves (59%), approximately 34%
consisted of undeveloped reserves, which require substantial expenditures to
drill new wells to recover such reserves.  Recovery in amounts great enough to
significantly impact the results of the Partnership's operations and the
ultimate cash distributions to partners can only occur with the investment of
new capital.  As provided in the Partnership Agreement, the Partnership
expended all of the Investors' net commitments for the acquisition of Property
Interests many years ago, and it no longer has capital to invest.  No
additional development activities are contemplated by the Companion Partnership
on the properties in which the Partnership has a non-operating interest.  The
remaining non-producing reserves (25%) are estimated to be behind-pipe
reserves, which are unlikely to be producible for many years because
behind-pipe reserves always require completion in a different producing zone,
which does not take place until production is depleted from the currently
producing zone.
    

   
         Interest Holders' Tax Reporting.  Each Investor will continue to have
an income tax reporting obligation with respect to his SDIs as long as the
Partnership continues to exist.  There is no trading market for the SDIs, so
Investors generally are unable to dispose of their SDIs.  See "Partnership
Business and Financial Condition--No Trading Market" in this Supplement.
Following the sale of the Partnership's Property Interests and dissolution of
the Partnership, Investors will realize gain or loss under federal income tax
laws.  See "Summary of Federal Income Tax Consequences--Taxable Gain or Loss
upon Sale of Properties" herein.  Thereafter, Investors will have no further
tax reporting obligations with respect to the Partnership.  See "Summary of
Federal Income Tax Consequences--Liquidation of the Partnership" in this
Supplement.

COLLECTIVE ANALYSIS OF PURCHASE PRICE; PREMIUM OVER FAIR MARKET VALUE

         The Special Transactions Committee selected H.J. Gruy and Associates,
Inc. ("H.J. Gruy" or "Gruy"), J.R. Butler and Company ("J.R. Butler" or
"Butler"), which are both petroleum engineering consultants, and CIBC
Oppenheimer Corp.  ("CIBC Oppenheimer"), an investment banking firm, to
estimate the fair market value of the Property Interests of each of the
Partnerships.  Collectively, H.J. Gruy, J.R. Butler and CIBC Oppenheimer are
referred to herein as the "Appraisers," and H.J. Gruy and J.R. Butler together
are sometimes referred to herein as the "Petroleum Engineering Consultants."





                                       9
<PAGE>   326
         The following subsections of the "Special Factors" section of the
Joint Proxy Statement/Prospectus should be reviewed for information concerning
the selection and qualification of the Appraisers and the parameters of the
valuation estimates: "Independent Appraisal of the Fair Market Value of
Property Interests of the Partnerships," "Qualification of Appraisers," and
"Fair Market Value."

   
         The Petroleum Engineering Consultants arrived at a fair market
valuation estimate based upon appraisal of the projected discounted cash flow
from its various Property Interests.  On the other hand, the investment banking
firm of CIBC Oppenheimer made a valuation estimate of the Partnership's
Property Interests based upon the application of multiple quantitative and
qualitative factors.  The quantitative factors include, among other things, a
review of relevant valuation criteria from comparable acquisitions of both oil
and gas properties and companies that are predominantly active in the oil and
gas industry, and a review of valuation criteria for relevant publicly traded
oil and gas companies.
    

         The process used by the Petroleum Engineering Consultants in preparing
their valuation estimate is discussed at length in the Joint Proxy
Statement/Prospectus under "Special Factors--Valuation by Petroleum Engineering
Consultants." As described therein, the Petroleum Engineering Consultants
individually audited the estimate of present value of future net cash flows
from the 44 property groups in which Property Interests are owned by the
Partnerships to whom similar proposals are being made to sell all of their oil
and gas assets and liquidate their Partnerships.  The Partnership owns Property
Interests in five of these property groups.  The Petroleum Engineering
Consultants began their analysis based upon the year-end 1997 PV-10 Value of
each property audited by H.J. Gruy and together they re-evaluated reserve
quantities, projected operating costs and cash flows.  The present value of
this reserves analysis was then derived by escalating year-end 1997 prices
($2.38 per MMBtu and $16.00 per barrel before adjustments for Btu content for
gas and gravity variances for oil as well as transportation charges and
geographic location) and costs by 3.5% per year for 15 years.  This present
value was then adjusted for various individual field risks and risk adjustments
of proved non- producing reserves and proved undeveloped reserves.  The result
of this collective analysis by the Petroleum Consulting Engineers was their
estimation that the fair market value of Property Interests owned by the
Partnership was $1,234,678 as of December 31, 1997.

   
         The methodology used by CIBC Oppenheimer to prepare its valuation
estimate is discussed at length under "Special Factors--Valuation by CIBC
Oppenheimer" in the Joint Proxy Statement/Prospectus.  CIBC Oppenheimer's
evaluation of the Partnership's Property Interests began with the PV-10 Value
of each property group, as calculated by Swift and audited by H.J. Gruy which
Gruy report dated February 10, 1998 is Attachment D to this Supplement.  CIBC
Oppenheimer then divided the property groups into two categories.  Those
property groups with reserves consisting primarily of proved developed
producing reserves were placed in the "Conventional Case" category.  Those
property groups with significant proved developed non-producing or undeveloped
reserves were placed in the "Non-Conventional Case" category.  [NEXT IS
VARIABLE SENTENCE:] The Partnership has interests in property groups which were
in both the "Conventional Case" and the "Non-Conventional Case" categories.
CIBC Oppenheimer then valued each property group by applying the multiples
discussed under "Special Factors--Valuation by CIBC Oppenheimer--Valuation
Multiples" in the Joint Proxy Statement/Prospectus to each property group's
PV-10 Value, proved reserves on a BOE basis, and projected 1998 EBIDTA.  A
separate set of multiples was used for property groups in the Conventional Case
category and the Non-Conventional Case category, respectively.  This provided
CIBC Oppenheimer with three estimated values for each property group.  The
average of these three values yielded CIBC Oppenheimer's estimation of the fair
market value of each property group.  CIBC Oppenheimer then allocated the
appropriate portion of each property group's
    





                                       10
<PAGE>   327
estimated fair market value to the Partnership based upon the Partnership's
Property Interests in each property group.  The result of this analysis by CIBC
Oppenheimer was an estimation that the fair market value of the Partnership's
Property Interests was $1,327,783 on December 31, 1997.

   
         The Special Transactions Committee has determined that, in keeping
with the definition of Fair Market Value, the higher of these two estimations
of fair market value, or $1,327,783, represents the Fair Market Value of the
Partnership's Property Interests.  Accordingly, the fair market value
estimation of the Petroleum Consulting Engineers and the fair market value
determined by CIBC Oppenheimer were compared to each other and the higher of
the two was chosen as the Fair Market Value of the Property Interests owned by
the Partnership.  The variation between the fair market value estimate of the
Partnership's Property Interests prepared by the Petroleum Consulting
Engineers, on one hand, and CIBC Oppenheimer on the other was 7%.
    

DETERMINATION OF PREMIUM OVER FAIR MARKET VALUE BY THE COMPANY

   
         The Special Transactions Committee presented its recommendation to the
Board of Directors of the Company as to the Fair Market Value of the Property
Interests of the Partnership.  The Board of Directors of the Company then
determined that paying a 7.5% premium over the Fair Market Value of the
Partnership's Property Interests was appropriate and fair based upon the
factors and for the reasons discussed below.  Because the Company has served as
Managing General Partner of the Partnership for over five years, it is
intimately familiar with the Property Interests owned by the Partnership.  The
Managing General Partner believes that if the Property Interests were to be
sold to a third party purchaser that was not equally familiar with those
interests, it is likely that the purchaser would discount the purchase price to
account for that lack of familiarity and associated risks.  If these interests
are purchased by the Company, then the additional cost and personnel often
inherent in making a property acquisition are not required, because the files
and deed records already exist in the Company's lease and computer systems, and
conveyance and title issues do not exist.
    

         In the judgment of the Company, the purchase of the Partnership's
Property Interests together with interests in many of the same properties owned
by other Partnerships at approximately the same time will result in
efficiencies to the Company in aggregating such interests.  Swift's long-term
knowledge of the risks involved in these properties means that it is in a
better position to evaluate these risks than third parties.

         Based upon the Company's experience in purchasing properties, the lack
of additional costs often incurred in purchasing oil and gas properties in
which the purchaser has owned no interest, and the Company's intimate
familiarity with these Property Interests and consequent ability to evaluate
acquisition risks, it was deemed appropriate to pay a premium representing the
benefit to the Company arising from these factors.

   
         The amount of the premium principally was based upon management's
experience in purchasing properties which contain both producing reserves and
drilling potential, without any statistical or analytical study prepared by the
Company in the course of determining the amount of this premium. Since 1979,
the Company, on behalf of itself and others, has gained a wide range of
experience with the valuation of oil and gas properties and the prices for
their purchase and sale, having purchased $478 million of such properties in
129 separate transactions.  Other purchasers might have determined it
inappropriate to pay  a premium, or if so, to pay a premium based upon other
factors or in a different amount.  Because there
    





                                       11
<PAGE>   328
   
has been no independent third party involved in the decision to pay this
premium or in the determination of its amount, and no fairness opinion has been
requested regarding this premium, conflicts of interest exist in its
determination, although the Managing General Partner believes, based upon its
knowledge of the oil and gas industry, its knowledge of the properties
involved, its experience in purchasing and selling oil and gas properties, and
the benefits from purchasing the Property Interests which are particular to the
Company, that the amount being offered to the Partnership to purchase its
Property Interests is fair.
    

"SPECIAL FACTORS" SECTION IN THE JOINT PROXY STATEMENT/PROSPECTUS

   
         The Special Factors section in the Joint Proxy Statement/Prospectus
contains a full discussion of the determination of the purchase price proposed
to be paid by the Managing General Partner to purchase the Partnership's
Property Interests.  In addition to those topics discussed at length in this
Supplement, the Joint Proxy Statement/Prospectus addresses alternative
transactions that were considered but not proposed for the Partnership and the
other 62 partnerships to whom similar proposals are being made simultaneously.
It also contains information regarding the prior relationships between the
Appraisers, the Partnerships and the Managing General Partner, the absence of a
request that an independent representative negotiate the terms of the purchase
of the Partnership's Property Interests by the Managing General Partner, the
manner in which expenses are to be borne for the transaction, the Managing
General Partner's source of funds to purchase the Partnership's Property
Interests, and the benefits that the Managing General Partner would receive
from purchasing such Property Interests.
    

ESTIMATES OF LIQUIDATING NET CASH DISTRIBUTION AMOUNT IF THE PROPOSAL IS
APPROVED

   
         The purchase price proposed to be paid to the Partnership for its oil
and gas assets is the Fair Market Value plus the purchase premium.  As is the
case with all oil and gas properties purchases, the purchase is proposed to be
made as of the date which the properties were evaluated (in this case December
31, 1997).  A portion of the reserves used to establish the Fair Market Value
has been produced during 1998.  Most of the net revenue received by the
Partnership from the sale of such production since the proposed purchase date
(December 31, 1997) has been distributed to the partners during 1998 through
quarterly cash distributions or, to the extent not already distributed, will be
distributed as part of the Partnership's liquidating distribution.
Accordingly, the actual purchase price which will be paid to the Partnership
will be reduced by the amount of net production revenue received by the
Partnership after December 31, 1997.
    

   
         Set forth in the table below are estimated net proceeds that the
Partnership may realize from the sale of the Partnership's Property Interests,
estimated expenses of the related dissolution and liquidation of the
Partnership and estimated interim net cash distributions from January 1, 1998
until September 30, 1998, resulting in an estimate of the amount of net cash
distributions available for Investors as a result of such sale.

         to September 30, 1998.

(6)      Estimated net cash distributions are allocated to the Investors and
         the General Partners pursuant to the Partnership's limited partnership
         agreement.

(7)      Includes amount distributable to Special General Partner and Managing
         General Partner.

(8)      Under the terms of the offer of Swift Common Stock to Eligible
         Purchasers, if the Investors in the Partnership approve the Proposal
         and its Companion Partnership approves a similar Proposal, such
         Investors will be Eligible Purchasers.  The minimum number of shares
         which can be purchased by an Eligible Purchaser is a round lot of 100
         shares.  Based upon estimated net cash distribution of $0.20 per $1.00
         SDI, the number of SDIs shown above is the minimum number of SDIs
         which it will be necessary for an Investor

         to own in order to purchase a minimum 100 share round lot of Swift
         Common Stock without providing any additional funds from other
         sources.  This calculation is based upon an assumed purchase price of
         Swift Common Stock of $18.00 per share (which is the same price upon
         which the proforma financial statements contained in the Joint Proxy
         Statement/Prospectus are based) for an aggregate purchase price for
         100 shares of Swift Common Stock of $1,800.  The minimum number of
         Units shown is subject to change, based upon the price for Swift
         Common Stock at a future date as specified under "Offering of Shares
         of Swift Energy Company Common Stock if Investors Approve the
         Proposal--Offer of Swift Common Stock--Purchase Price" in this
         Supplement. However, if an Eligible Purchaser has interests in more
         than one Partnership, the cash distributions he will be entitled to
         receive may be aggregated to meet the minimum share purchase
         requirement of a round lot of 100 shares.
    

ESTIMATES OF NET CASH DISTRIBUTIONS AVAILABLE FROM CONTINUED OPERATIONS

   
         If the Partnership were to retain its Property Interests until they
have reached their economic limit, the table below estimates the return to
Investors, without regard to amounts distributable to the General Partners,
discounted to present value, based upon 1997 year-end pricing without
escalation and upon the discount assumptions used above.  The estimates of the
present value of future net cash distributions have been further reduced by
estimates of 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.
The following estimated future net revenues do not take into account any
additional costs which might be incurred by the Partnership's Companion
Partnership due to needed future maintenance or remedial work on the properties
in which the Partnership has an interest, which would reduce such net revenues.

         1998 to September 30, 1998 in order to present this information on a

         30, 1998.
    

(3)      Includes Investors' share of general and administrative expenses, and

         economic limit.

(6)      Discounted at 10% per annum.

         The proceeds of all sales, to the extent available for net cash
distribution, are to be distributed to the partners in accordance with the
Partnership's limited partnership agreement.  The amounts finally distributed
will depend on the actual sales prices received for the Partnership assets,
results of operations until liquidation of the Partnership, final costs and
other contingencies and circumstances.

   
FAIRNESS OF PROPOSED SALE OF ASSETS TO THE MANAGING GENERAL PARTNER
   AS COMPARED TO CONTINUING OPERATIONS
    

   
         Based on the above tables, it is estimated that an Investor could
expect to receive $0.20 per $1.00 SDI upon the sale of the Partnership's
Property Interests as of September 30, 1998.  In comparison, it is estimated
that an Investor could expect to receive $0.25 per $1.00 SDI, discounted to
present value at 10% per annum ($0.39 per $1.00 SDI on an undiscounted basis)
if the Partnership continued operations.  The Managing General Partner believes
that the Proposal to sell the Partnership's Property Interest as compared to
continuing operations is fair to Investors for the reasons discussed below.
    

   
         Although the estimates contained in the two tables above show that
estimated net cash distributions to Investors (based on net present value) from
continued operations would be approximately 25% higher than estimated net cash
distributions from selling the Partnership's Property Interests and liquidating
the Partnership currently, the Managing General Partner believes there is a
substantial advantage in receiving the liquidating net cash distribution in one
lump sum at this time. The estimates of net cash distributions from continued
operations are based upon 1997 year- end pricing.  It is highly likely that
over such a long period of time, oil and gas prices will vary often and
possibly widely, as has been demonstrated historically, from the prices used to
prepare these estimates.  Continued operations over such a long period of time
subject Investors to the risk of receiving lower levels of net cash
distributions if oil and gas prices over this period are lower on average than
those used in preparing the estimates of net cash distributions from continued
operations.  Continued operations also subject Investors' potential net cash
distributions 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.  The Managing General Partner also believes that there
is an advantage to Investors taking any funds to be received upon liquidation
and redeploying those assets in other investments, rather than continuing to
receive decreasing levels of net cash distributions over such a long period of
time.
    





                                       15
<PAGE>   332
   
         Because there is no active trading market for SDIs in the Partnership,
the only other comparable value for SDIs is the 1997 "SDI Value," which, as
explained below, is the amount calculated on an annual basis under the terms of
the limited partnership agreement at which the Managing General Partner can
offer to repurchase SDIs from Investors.  As of January 1, 1997, this "SDI
Value" was $0.37 per $1.00 SDI.  In 1997, the Investors received net cash
distributions of $0.08 per $1.00 SDI, and are estimated to receive another
$0.05 per $1.00 SDI before September 30, 1998, which converts to a comparable
value of $0.24 per $1.00 SDI before any adjustments to quantities of reserves
or oil and gas prices during this almost two year period.  Under the terms set
out in the partnership agreement, each year the Managing General Partner is
required to furnish to Investors the SDI Value, and Investors have the right to
present their SDIs for purchase by the Managing General Partner for the SDI
Value.  The SDI Value amount is determined on an entirely different basis than
the estimates of fair market value by the Appraisers.  Furthermore, the SDI
Value was calculated over one year ago, with a valuation date of January 1,
1997, as opposed to the date for assessment of Fair Market Value being December
31, 1997. Because of significant changes in oil and gas prices within a year's
time, in addition to the changes in reserve quantities during that period, the
calculation of SDI Value as of January 1, 1997, and the Fair Market Value as of
December 31, 1997, are not comparable.  SDI Value is derived by taking 70% of
the present value of proved oil and gas reserves (discounted at 10% per annum)
calculated on an escalated pricing basis, plus cash and accounts receivable
less outstanding debts and obligations of the Partnership.
    

         Although the PV-10 Value of the Partnership's Property Interests is
higher than the purchase price proposed if the Proposal is approved, the
Managing General Partner does not believe that the PV-10 Value accurately
reflects the amount that oil and gas industry members are currently paying to
purchase producing properties on the open market.

FAIRNESS OF PROPOSED SALE

   
         The Managing General Partner believes that the entire transaction
related to the Proposals involving the proposed method of sales of the
Partnerships' Property Interests is fair to Investors for the following
reasons, without giving any particular weight to any reason:
    

   
         1.      The Managing General Partner believes that the most important
                 element of the Proposal is the determination of the Fair
                 Market Value of the Partnership's Property Interests.  The
                 price to be paid by the Company to purchase the Partnership's
                 Property Interests was determined in the Managing General
                 Partner's sole judgment by adding a 7.5% premium to the higher
                 of the two estimates by the Appraisers of the fair market
                 value of the Partnership's Property Interests.  Two of the
                 three Appraisers are qualified independent petroleum
                 engineering firms and the other is an investment banking firm.
                 The factors and methods used by the Appraisers in determining
                 Fair Market Value are discussed in detail under "Special
                 Factors--Independent Appraisal of the Fair Market Value of
                 Property Interests of the Partnerships",  "--Fair Market
                 Value," "--Valuation by Petroleum Engineering Consultants,"
                 "--Valuation by CIBC Oppenheimer" and "--Collective Analysis
                 of Purchase Price" in the Joint Proxy Statement/Prospectus.
    

   
         2.      No transaction will take place unless the Proposal is approved
                 by Investors holding at least a majority of the interests in
                 such Partnership (without any vote by the Managing General
                 Partner) and a similar Proposal is approved by the
                 Partnership's Companion Partnership.
    





                                       16
<PAGE>   333
         3.      The Special Transactions Committee made the determination as
                 to the retention of the Appraisers and approved the fair
                 market value estimates provided by the Appraisers and
                 recommended the reports of the Appraisers to the Board of
                 Directors of the Company.  The Special Transactions Committee
                 is comprised solely of independent directors of the Company.

   
         4.      If the Proposals are approved by investors in any of the 63
                 Partnerships considering similar proposals, it is likely that
                 the Managing General Partner will expend the capital necessary
                 to develop non- producing reserves on the Property Interests
                 purchased by the Managing General Partner from those
                 Partnerships.  If all of the Property Interests which are the
                 subject of the Proposals are acquired by the Company, such
                 Property Interests in the aggregate will constitute less than
                 20% of the Company's total assets.  Because the Managing
                 General Partner would be the beneficiary of any such increase
                 in value, the Managing General Partner is hereby offering to
                 Eligible Purchasers the opportunity to purchase up to
                 2,500,000 shares of Common Stock of the Company.  There is no
                 requirement that any purchase of Swift's Common Stock be made.
                 See "Offer of Swift Common Stock" below.
    

   
         5.      In structuring the Proposal and related transactions, the
                 Managing General Partner considered that any sale of
                 Partnership Property Interests, whether to the Managing
                 General Partner or to a third party, would be a taxable
                 transaction.  Thus, if an Investor subject to federal income
                 tax chooses to use the proceeds received on liquidation of
                 that Investor's Partnership to purchase Swift Common Stock,
                 tax will still have to be paid on any taxable income resulting
                 from the Partnership's sale of oil and gas assets, without
                 regard to whether the Investor has cash proceeds remaining
                 from his liquidating distribution to pay such tax. Investors
                 that purchased their interests in the original offering,
                 however, are not expected to recognize gain on the sale.
    

   
         The determination by the Special Transactions Committee to pay the
purchase premium, the independent Appraisers' determination of the fair market
value of the properties, and the payment of a 7.5% premium do not necessarily
remove the substantial conflicts of interest which exist in the transaction
between the Company serving as Managing General Partner of the Partnership and
also acting as the purchaser of the Property Interests from the Partnership.
No fairness opinion was requested or received regarding the ultimate purchase
price to be paid by the Company to purchase the Partnership's oil and gas
assets.  The Company determined that rather than setting the purchase price for
Partnership Property Interests itself, it would be preferable to instead
request three different independent Appraisers to determine two sets of fair
market values at which such Property Interests should be purchased and then to
choose the higher of those two values.  The Managing General Partner believes
that when the Appraisers rendered their opinions as to the "fair market value"
of the Partnership's Property Interests, inherent within their appraisal
opinions were the Appraisers' determination that these "fair market values"
were "fair," or such determinations would not have been made.  Consequently, no
independent fairness opinion was requested regarding "fair market values" or
upon the premium.  The Managing General Partner believes that adding a 7.5%
premium to the highest of the two fair market value determinations made by the
three Appraisers only serves to increase the amount to be paid to Investors
upon liquidation of the Partnership and does not require a separate fairness
opinion.  The determination by a third party purchaser as to the purchase price
might be more or less than that being proposed by the Managing General Partner
as a purchase price for these Property Interests.
    





                                       17
<PAGE>   334
   
         The determination to submit the Proposal to Investors in which the
Company would purchase the Property Interests of the Partnership was deemed by
the Managing General Partner to be the most appropriate time and method for
liquidation of the Partnership.  This decision was made in light of full
consideration by the Managing General Partner of its fiduciary obligations to
Investors.  Furthermore, the decision to use three Appraisers, rather than one,
and to have the Appraisers actually set the fair market value for purchase of
the Property Interests, rather than the Managing General Partner setting that
value and requesting a fairness opinion, were based upon the Managing General
Partner's consideration of the substantial conflicts of interest which exist in
the transactions covered hereby.
    

See "Special Factors--Fairness of Proposed Sale" in the Joint Proxy
Statement/Prospectus.

   
MANAGING GENERAL PARTNER BENEFITS
    

   
         Benefits accruing to the Company resulting from the purchase of the
Partnerships' Property Interests include the following:  the Managing General
Partner will share the benefits available to Investors through liquidating its
Partnership interests (including both its general partner interests and any
SDIs it owns) and receiving the same value of those interests as Investors.
Additionally, the Company intends to profit from purchasing the Partnership's
Property Interests through a return on capital used to purchase those oil and
gas assets and invest in their development.  By purchasing the Partnership's
Property Interests itself, the Managing General Partner will be able to
maintain its position as operator of certain properties in which the
Partnership owns an interest.  Consequently, the Managing General Partner would
continue to receive operating fees as operator of those properties.  The sale
of the Partnership's Property Interests to the Managing General Partner will
have no effect or an inconsequential effect on the Managing General Partner's
net book value and net earnings.  However, the purchase of all of the oil and
gas assets of the Partnerships would increase the Company's proved reserves,
cash flow and total assets by a significant amount.  Lastly, if individual
Investors which approve the Proposal elect to purchase Company Common Stock,
rather than receiving cash upon liquidation of the Partnership, the Company
will benefit by using stock to pay the purchase price, rather than using its
available cash resources or borrowing facilities.
    

See "Special Factors--Managing General Partner Benefits" in the Joint Proxy
Statement/Prospectus.

SIMULTANEOUS PROPOSALS TO COMPANION PARTNERSHIPS

   
         Simultaneous Proposals are being made to investors in the
Partnership's Companion Partnership.  If both the Partnership and its Companion
Partnership do not approve their respective Proposals, it is likely to affect
the ability of the Partnership to consummate the sale of its Property
Interests.  Although the Investors in the Partnership may desire to sell their
Property Interests, the separation of the working interest and the
non-operating interests in the same properties may affect the salability of
those interests on a permanent basis.  If, for example, the Partnership
approves the Proposal but the Companion Partnership does not, the value of a
non-operating interest is likely to be negatively affected by the lack of
control over operations.  [VARIABLE REVERSAL:  If, for example, the Partnership
approves the Proposal but the Companion Partnership does not, the value of a
working interest burdened by a large non- operating interest is likely to be
lowered significantly.]  If the Partnership's Companion Partnership does not
approve its Proposal, then the Managing General Partner will advise the
Investors in the Partnership.  If the investors in the Partnership's Companion
Partnership do not vote in favor of its Proposal, then it is likely that the
Partnership will continue  operations and will produce its reserves until
depletion, with steadily decreasing rates of cash flow, and consequently
steadily decreasing amounts of cash distributions to the Investors.

                             VOTING ON THE PROPOSAL

   
         The Joint Proxy Statement/Prospectus and the Proxy enclosed with this
Supplement are being provided for use at the Special Meeting of Investors of
the Partnership and at any adjournment or postponement of such meeting (the
"Meeting") to be held at 16825 Northchase Drive, Houston, Texas at 4:00 p.m.
Central Time on _______, __________, 1998.  The Meeting is being called for the
purpose of considering and voting upon the Proposal to ultimately sell all of
the oil and gas assets of the Partnership to the Company, and to dissolve, wind
up and terminate the Partnership, and to transact such other business as may be
properly presented at the Meeting, all in accordance with the terms and
provisions of the Partnership's limited partnership agreement (the "Partnership
Agreement"), and the Texas Revised Limited Partnership Act (the "Texas Act").
This Joint Proxy Statement/Prospectus and enclosed Form of Proxy are first
being mailed to Investors on or about ____________, 1998.
    

   
          Pursuant to the terms of the Partnership Agreement, the Partnership,
if not terminated earlier, will continue in being through December 31, 2021, at
which point it will terminate automatically.
    

   
         Under the Partnership Agreement, the Proposal must be approved by the
affirmative vote of Investors holding more than 50% of SDIs in the Partnership
as of the Record Date (defined below).  Therefore, an abstention by an Investor
will have the same effect as a vote against the Proposal.  The solicitations
are being made for votes in favor of the Proposal (which will result in
liquidation and dissolution of the Partnership).  As of the Record Date,
6,076,102 SDIs were outstanding and held by record holders (excluding the SDIs
held by the Managing General Partner).  Accordingly, the affirmative vote of
holders of at least 3,038,052 SDIs is required to approve the Proposal.   Each
Investor appearing on the records of the Partnership as of ______, 1998 (the
"Record Date") is entitled to notice of the Meeting and is entitled to one vote
for each SDI held by such Investor.  VJM Corporation, a California corporation,
is the Special General Partner of the Partnership, and owns a 0.75% interest in
the Partnership as a general partner, but owns no SDIs.  The Managing General
Partner owns a general partner interest in the Partnership of 14.25%.
Additionally, the Managing General Partner owns 161,000 outstanding SDIs in the
Partnership, which ownership results from the Managing General Partner's
purchase over the life of the Partnership of SDIs from Investors under the
right of presentment, contained in the Partnership Agreement.  Under the
Partnership Agreement, the Managing General Partner may not vote any SDIs owned
by it for matters such as the Proposal.  The Managing General Partner's
non-vote, in contrast to abstention by Investors, will not affect the outcome,
because for purposes of adopting the Proposal, its SDIs are excluded from the
total number of voting SDIs.
    

VOTE REQUIRED

         The actual proxy to be used to register the vote on the Proposal
before you is the separate green sheet of paper included with this Supplement
and Joint Proxy Statement/Prospectus.  PLEASE USE THE GREEN PROXY TO CAST YOUR
VOTE ON THE PROPOSAL.

         If a proxy is properly signed and is not revoked by an Investor, the
SDIs it represents will be voted in accordance with the instructions of the
Investor.  If no specific instructions are given, the SDIs will be voted FOR
the Proposal.  An Investor may revoke his proxy at any time before it is voted
at the Meeting.





                                       19
<PAGE>   336
Any Investor who attends the Meeting and wishes to vote in person may revoke
his proxy at that time.  Otherwise, an Investor 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.

SOLICITATION

   
         The solicitation is being made by the Partnership.  The Partnership
will bear the costs of the preparation of the Joint Proxy Statement/Prospectus
and of the solicitation of proxies and such costs will be allocated 85% to the
Investors and 15% to the general partners pursuant to the terms of the
Partnership Agreement.  As the Managing General Partner holds approximately
2.58% of the SDIs held by all Investors, 2.58% of the costs borne by the
Investors will be borne by the Managing General Partner, in addition to the
portion of the Partnership's total costs borne by the general partners by
virtue of their interest in the Partnership as general partners.  Solicitations
will be made primarily by mail.  In addition, a number of regular or temporary
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 Investors to encourage the return of proxies, although it does not
anticipate doing so.
    

                  PARTNERSHIP BUSINESS AND FINANCIAL CONDITION

   
         The Partnership is a Texas limited partnership formed June 30, 1993.
SDIs in the Partnership are registered under Section 12(g) of the Securities
Exchange Act of 1934.  The Partnership owns non-operating Property Interests in
producing oil and gas properties within the continental United States in which
the Companion Partnership also managed by the Managing General Partner owns the
working interests.  By the end of October 1993,  the Partnership had expended
all of its original capital contributions for the purchase of Property
Interests in oil and gas producing properties.  During 1997, approximately 58%
of the Partnership's revenue was attributable to natural gas production. From
time to time, the Companion Partnership has performed workovers and
recompletions on wells in which the Partnership has non- operating interests,
using funds advanced by the Managing General Partner to perform these
operations, which amounts have been subsequently repaid.  For information about
the business of the Partnership, see the attached Annual Report on Form 10-K
for the year ended December 31, 1997 and Quarterly Report on Form 10-Q for the
quarter ended June 30, 1998.
    

   
         Investors made contributions of $6,237,102, in the aggregate to the
Partnership, the net proceeds of which has all been invested.  The Managing
General Partner has made capital contributions with respect to its general
partner interest of $810,823.  Additionally, pursuant to the right of
presentment set forth in the Partnership Agreement, it has purchased 161,000
SDIs from Investors.  From inception through July 31, 1998, the Partnership has
made net cash distributions to its Investors totaling $2,760,200.  Details of
the amounts of cash distributions made to partners over the past three years
and nine months are set out under "Cash Distributions" below.  Through July 31,
1998, the Managing General Partner has received net cash distributions from the
Partnership of $453,472 with respect to its general partner interest, and
$35,724 related to the number of SDIs it purchased from Investors.  On a per
SDI basis, Investors had received, as of July 31, 1998, $0.44 per $1.00 SDI, or
approximately 44.3% 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.  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 $19.70 per
barrel of oil and $2.06 per Mcf of natural gas.  The majority of the
Partnership's Property Interests were acquired by the end of October 1993 and
were comprised principally of natural gas reserves.  At that time current
prices were predicted to escalate according to certain parameters from then
current levels to approximately $25.05 per barrel of oil and $2.63 per Mcf of
natural gas during 1997.  The predicted price increases did not occur, and
prices fell precipitously from 1994 to 1995.  Most of the Partnership's
reserves were produced from 1993 to 1997, during which time the oil prices
received by the Partnership for its production in fact averaged $16.48 per
barrel, but the prices for the Partnership's principal asset, natural gas,
averaged approximately $2.14 per Mcf.  A comparison of oil and gas prices as
described in this paragraph appears in the graph presented below.
    

         The following graphs illustrate the effect on Partnership performance
of the variance between oil and gas prices projected at the time of acquisition
of the Partnership's Property Interests and actual oil and gas prices received
for production (as illustrated in the second graph) during the Partnership's
existence.

<PAGE>   340
         Lower prices also have 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.

CASH DISTRIBUTIONS

   
         Cash distributions are made to the partners in the Partnership on a
quarterly basis.  During the past three years and the first nine months of
1998, aggregate cash distributions made to all partners in the Partnership
(including the Managing General Partner) and the cash distributions per SDI
made to the Investors were:

TRANSACTIONS BETWEEN THE MANAGING GENERAL PARTNER AND THE PARTNERSHIP

   
         Under the Partnership Agreement, the Managing General Partner has
received certain compensation for its services and reimbursement for
expenditures made on behalf of the Partnership, which was paid at closing of
the offering of SDIs, in addition to revenues distributable to the Managing
General Partner with respect to its general partner interest or with respect to
SDIs it has purchased under the Investors' right of presentment.  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 internal acquisition
                 costs reimbursements of $297,224 from the Partnership from
                 inception through December 31, 1997, none of which has been
                 received during the two years ended December 31, 1997.

   
         o       The Managing General Partner receives operating fees for wells
                 in which the Partnership has Property Interests and for which
                 the Managing General Partner or its affiliates serve as
                 operator.  During the years ended December 31, 1997 and
                 December 31, 1996 the aggregate operating fees paid to the
                 Company as operator by the Partnership were $38,127 and
                 $43,502, respectively.  Monthly operating fees range from $400
                 to $1,500 per well on an 8/8th's basis (i.e., the total amount
                 of operating fees paid by all interest owners in the well).
                 If the Property Interests are sold to the Managing General
                 Partner, there should be no change in its status as operator
                 for a number of the wells in which the Partnership has a
                 Property Interest.  The Managing General Partner believes that
                 it will be positively affected, on the other hand, by
                 liquidation of the Partnership, both on the basis of its
                 ownership interest in the Partnership and for other reasons
                 set out under "Special Factors--Managing General Partner
                 Benefits" in this Supplement.
    





                                       24
<PAGE>   341
         o       The Managing General Partner is entitled to be reimbursed 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
                 Investors' original capital contributions to the Partnership
                 relative to investor contributions to all public partnerships
                 formed to purchase interests in producing properties for which
                 the Managing General Partner serves in that capacity.  Through
                 December 31, 1997, the Managing General Partner had received
                 $458,444 in the general and administrative overhead allowance
                 from the Partnership, of which $93,557 and $93,557 have been
                 reimbursed during the years ended December 31, 1997 and
                 December 31, 1996, respectively.

         o       The Managing General Partner has been reimbursed $12,908 in
                 direct expenses by the Partnership, all of which was billed
                 by, and then paid directly to, third party vendors, of which
                 $2,280 and $3,127 have been reimbursed during the years ended
                 December 31, 1997 and December 31, 1996, respectively.

         o       The Managing General Partner has received a nonaccountable
                 incentive amount of $123,405 for services rendered from
                 inception through December 31, 1997, of which $8,029 and
                 $9,218 have been reimbursed during the years ended December
                 31, 1997 and December 31, 1996, respectively.

NO TRADING MARKET

   
         There is no trading market for the SDIs, and none is expected to
develop, as described above under "Special Factors--Fairness of Proposed Sale
of Assets to the Managing General Partner as Compared to Continuing
Operations." Under the Partnership Agreement, Investors have the right to
present their SDIs to the Managing General Partner for repurchase at a price
determined in accordance with the formula established by the Partnership
Agreement.  Originally 576 Investors invested in the Partnership.  As of
__________, 1998, there were 559 Investors (excluding the Managing General
Partner).  The number of SDIs in the Partnership issued and outstanding at that
date was 6,237,102.  Through December 31, 1997, the Managing General Partner
had purchased 161,000 SDIs from Investors pursuant to the right of presentment.
The Managing General Partner does not have an obligation to repurchase Investor
interests pursuant to this right of presentment, but merely an option to do so
when such interests are presented for repurchase.
    

PRINCIPAL HOLDERS OF INVESTOR SDIS

         The Managing General Partner holds 2.58% of all outstanding SDIs of
the Partnership, resulting from the purchase of SDIs from Investors under their
right of presentment.  To the knowledge of the Managing General Partner, there
is no holder of SDIs that holds more than 5% of the SDIs.

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.

   
    
                   SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES

GENERAL

   
         The following briefly summarizes the federal income tax consequences
set forth under "Federal Income Tax Consequences of Adoption of the Proposals"
in the Joint Proxy Statement/Prospectus.  Statements of legal conclusions
herein regarding tax consequences are based upon an opinion of Hoops and Levy,
L.L.P., Special Tax Counsel, 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 reported judicial decisions and published
positions of the Internal Revenue Service (the "Service"), a private letter
ruling dated February 6, 1991 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 Investors.
    

   
         A MORE COMPLETE SUMMARY OF THE FEDERAL INCOME TAX CONSEQUENCES TO
INVESTORS MAY BE FOUND IN THE REGISTRATION STATEMENT IN "FEDERAL INCOME TAX
CONSEQUENCES OF ADOPTION OF THE PROPOSALS."  THIS SUMMARY DOES NOT DESCRIBE ALL
THE TAX ASPECTS WHICH MAY AFFECT INVESTORS NOR IS IT A COMPLETE DESCRIPTION OF
THE TAX ASPECTS IT DOES DESCRIBE.  It is generally directed to Tax Exempt Plans
that are Investors who are the original purchasers of the SDIs and hold
interests in the Partnership as "capital assets" (generally, property held for
investment).  Each Investor that is a corporation, trust, estate, or other
partnership 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

         Tax Exempt Plans are subject to tax on their unrelated business
taxable income ("UBTI").  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.





                                       26
<PAGE>   343
         The Internal Revenue Service has previously ruled that the
Partnership's net profits interest, as structured under the net profits
agreement, 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 Investors that are Tax
Exempt Plans either taxable gain or loss for federal income tax purposes, even
though there may be gain or loss upon the sale of the Property Interest for
federal income tax purposes.

         DEBT-FINANCED PROPERTY

         Debt-financed property is property held to produce income that is
subject to acquisition indebtedness.  The income is taxable in the same
proportion which the debt bears to the total cost of acquiring the property.
Generally, acquisition indebtedness is the unpaid amount of (i) indebtedness
incurred by a Tax Exempt Plan to acquire an interest in a partnership, (ii)
indebtedness incurred in acquiring or improving property, or (iii) indebtedness
incurred either before or after the acquisition or improvement of property or
the acquisition of a partnership interest if such indebtedness would not have
been incurred but for such acquisition or improvement, and if incurred
subsequent to such acquisition or improvement, the incurrence of such
indebtedness was reasonably foreseeable at the time of such acquisition or
improvement.

         If an Investor 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.  If a Tax Exempt Plan has not caused its
Partnership Interest to be debt-financed property, and based upon
representations of the Managing General, the Property Interest is not expected
to be considered debt-financed property.

TAX TREATMENT OF INVESTORS SUBJECT TO FEDERAL INCOME TAX DUE TO DEBT-FINANCING

         All references hereinbelow to Investors refers solely to Investors
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.

         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 an Investor's income, gain,
loss and deduction from the Partnership is subject to federal taxation.





                                       27
<PAGE>   344
         TAXABLE GAIN OR LOSS UPON SALE OF PROPERTIES

   
         Investors will realize and recognize gain or loss, or a combination of
both, upon the Partnership's sale of its properties prior to liquidation.  It
is projected, however, that Investors will realize a net taxable loss upon the
sale of the Partnership properties.
    

         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 an Investor in liquidation is less than such Investor's adjusted
tax basis in his Partnership interest, the Investor will realize and recognize
a capital loss to the extent of the excess.  If the amount of cash distributed
is greater than such Investor's adjusted tax basis in his Partnership interest,
the Investor will recognize a capital gain to the extent of the excess.

         CAPITAL GAIN TAX

         Net long-term capital gains of individuals, trusts and estates
generally will be taxed at a maximum rate of 20%, while ordinary income,
including income from the recapture of intangible drilling and development
costs, depreciation and depletion, will be taxed at a maximum rate depending on
that Investor's taxable income of 36% or 39.6%.


         PASSIVE LOSS LIMITATIONS

         Investors 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.

         An Investor'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.  An
Investor's share of any gain or loss realized upon the sale of the net profits
interest is expected to be characterized as portfolio income or loss and may
not be offset, or be offset by, passive activity gains or losses.

   
         THE FOREGOING DISCUSSION IS A SUMMARY OF THE INCOME TAX  CONSEQUENCES
SET FORTH UNDER "FEDERAL INCOME TAX CONSEQUENCES OF ADOPTION OF THE PROPOSALS"
IN THE JOINT PROXY STATEMENT/PROSPECTUS. IT IS NOT INTENDED AS AN ALTERNATIVE
FOR INDIVIDUAL TAX PLANNING.  EACH INVESTOR SHOULD CONSULT HIS, HER OR ITS OWN
TAX ADVISOR CONCERNING THE PARTICULAR FEDERAL, STATE, LOCAL, FOREIGN AND OTHER
TAX CONSEQUENCES APPLICABLE TO HIM, HER OR IT OF THE SALE OF PROPERTIES AND THE
LIQUIDATION OF THE PARTNERSHIP.

OFFER OF SWIFT COMMON STOCK
    

         Investor Election to Purchase Shares

   
         In connection with the concurrent Proposals for sale of all of the oil
and gas assets of 63 Partnerships to the Company and the subsequent termination
of such Partnerships, the Company is offering up to 2,500,000 shares of the
Company's Common Stock.  Upon approval of the Proposals by the Partnership and
its Companion Partnership and sale of the Partnership's oil and gas assets, the
Partnership's assets will consist solely of cash which each investor as an
Eligible Purchaser of such Partnerships will be
    





                                       29

      Board of Directors              SWIFT ENERGY PENSION PARTNERS 1993-B, LTD.
                                      97-003-133


Gentlemen:

At your request, we have audited the proved, probable and possible reserves and
future net cash flow as of December 31, 1997, prepared by Swift Energy Company
("Swift") for certain interests owned by the partners in Swift Energy Pension
Partners 1993-B, Ltd. This audit has been conducted according to the Standards
Pertaining to the Estimating and Auditing of Oil and Gas Reserve Information
approved by the Board of Directors of the Society of Petroleum Engineers on
October 30, 1979. We have reviewed these properties and where we disagreed with
the Swift reserve estimates, Swift revised its estimates to be in agreement.

From this audit, and in consultation with J.R. Butler and Company, our estimate
of the fair market value of this partnership is $1,234,678.

Fair market value as used herein is defined as that price that a willing buyer
will pay and a willing seller will accept at a given point in time, with neither
the buyer nor the seller under any compulsion to buy or sell, and both having
reasonable knowledge of all the material circumstances.

To estimate the fair market value attributable to the proved developed producing
reserves, the 10 percent discounted future net cash flow was multiplied by a
suitable factor (less than one) to account for the risk associated with the
reserves, operating expenses, and prices and to approximate tax consequences.
The internal rate of return and payout time were computed for this quantity and
compared with those at which current acquisitions are completed. Suitable
adjustments are then made to correspond to these two financial indices. Proved
developed nonproducing, proved undeveloped, probable and possible reserves
require capital investments and must be treated appropriately. For these cases,
the capital is added to the discounted net cash flow, then multiplied by a
suitable risk factor and the capital then subtracted. This has the effect that
capital is spent with certainty and the operating cash income is burdened with
the risk. Internal rate of return and payout time is calculated for each
estimate to establish reasonableness based upon it the reserve category.

Swift Energy Company                    -2-                    April 17, 1998


The estimated future net cash flow is that cash flow which will be realized from
the sale of the estimated net reserves after deduction of royalties, ad valorem
and production taxes, direct operating costs and capital expenditures, when
applicable. Surface and well equipment salvage values and well plugging and
field abandonment costs have not been considered in the cash flow projections.
Future net cash flow as stated in this report is before the deduction of federal
income tax.

The following parameters are incorporated in the economic projections referenced
in this report. Initial oil prices are the existing prices on December 31, 1997,
and are escalated 3.5 percent per year beginning in 1999 through the year 2012
after adjusting for transportation and gravity variances. Initial natural gas
prices are those existing on December 31, 1997, and are escalated 3.5 percent
per year beginning in 1999 through the year 2012 after adjusting for
transportation and Btu content. Operating expenses are escalated at an annual
rate of 3.5 percent until the year 2012. The actual prices that will be received
and the associated costs may be more or less than those projected.

For those wells with sufficient production history, reserve estimates and rate
projections are based on the extrapolation of established performance trends.
Reserves for other producing and nonproducing properties have been estimated
from volumetric calculations and analogy with the performance of comparable
wells. The reserves referenced in this study are estimates only and should not
be construed as exact quantities. Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available. The proved reserves are
estimated in accordance with the definitions included in the Securities and
Exchange Commission Regulation S-X, Rule 4-10(a) except for the price and cost
escalations. The definitions are included in part as Attachment I. The probable
and possible reserves conform to the definitions approved by the Society of
Petroleum Engineers, Inc. The definitions are included as Attachment II.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented. The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December. Interim production to December 31, 1997, has been
estimated. Operating expenses as supplied by Swift were not audited, but were
reviewed for reasonableness. No independent well tests, property inspections or
audits of operating expenses were conducted by our staff in conjunction with
this study. We did not verify or determine the extent, character, obligations,
status or liabilities, if any, arising from any current or possible future
environmental liabilities that might be applicable.

In order to audit the reserves, costs and future cash flows referenced in this
report, we have relied in part on geological, engineering and economic data
furnished by our client. Although we have made a best efforts attempt to acquire
all pertinent data and to analyze it carefully with methods accepted by the
petroleum industry, there is no guarantee that the volumes of oil or gas or the
cash flows projected will be realized. The reserve and cash flow projections
referenced in this report may require revision as additional data become
available.

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                         PETROLEUM RESERVES DEFINITIONS
   SOCIETY OF PETROLEUM ENGINEERS (SPE) AND WORLD PETROLEUM CONGRESS (WPC)(1)

Reserves are those quantities of petroleum which are anticipated to be
commercially recovered from known accumulations from a given date forward. All
reserve estimates involve some degree of uncertainty. The uncertainty depends
chiefly on the amount of reliable geologic and engineering data available at the
time of the estimate and the interpretation of these data. The relative degree
of uncertainty may be conveyed by placing reserves into one of two principal
classifications, either proved or unproved. Unproved reserves are less certain
to be recovered than proved reserves and may be further sub-classified as
probable and possible reserves to denote progressively increasing uncertainty in
their recoverability.

The intent of the SPE and WPC in approving additional classifications beyond
proved reserves is to facilitate consistency among professionals using such
terms. In presenting these definitions, neither organization is recommending
public disclosure of reserves classified as unproved. Public disclosure of the
quantities classified as unproved reserves is left to the discretion of the
countries or companies involved.

Estimation of reserves is done under conditions of uncertainty. The method of
estimation is called deterministic if a single best estimate of reserves is made
based on known geological, engineering and economic data. The method of
estimation is called probabilistic when the known geological, engineering, and
economic data are used to generate a range of estimates and their associated
probabilities. Identifying reserves as proved, probable, and possible has been
the most frequent classification method and gives an indication of the
probability of recovery. Because of potential differences in uncertainty,
caution should be exercised when aggregating reserves of different
classifications.

Reserves estimates will generally be revised as additional geologic or
engineering data become available or as economic conditions change. Reserves do
not include quantities of petroleum being held in inventory, and may be reduced
for usage of processing losses if required for financial reporting.

Reserves may be attributed to either natural energy or improved recovery
methods. Improved recovery methods include all methods for supplementing natural
energy or altering natural forces in the reservoir to increase ultimate
recovery. Examples of such methods are pressure maintenance, cycling,
waterflooding, thermal methods, chemical flooding, and the use of miscible and
immiscible displacement fluids. Other improved recovery methods may be developed
in the future as petroleum technology continues to evolve.

PROVED RESERVES

Proved reserves are those quantities of petroleum which, by analysis of
geological and engineering data, can be estimated with reasonable certainty to
be commercially recoverable, from a given date forward, from known reservoirs
and under current economic conditions, operating methods, and government
regulations. Proved reserves can be categorized as developed or undeveloped.

If deterministic methods are used, the term reasonable certainty is intended to
express a high degree of confidence that the quantities will be recovered. If
probabilistic methods are used, there should be at least a 90% probability that
the quantities actually recovered will equal or exceed the estimate.

Establishment of current economic conditions should include relevant historical
petroleum prices and associated costs and may involve an averaging period that
is consistent with the purpose of the reserve estimate, appropriate contract
obligations, corporate procedures, and government regulations involved in
reporting these reserves.

In general, reserves are considered proved if the commercial producibility of
the reservoir is supported by actual production or formation tests. In this
context, the term proved refers to the actual quantities of petroleum reserves
and not just the productivity of the well or reservoir. In certain cases,
proved reserves may be assigned on the basis of well logs and/or core analysis
that indicate the subject reservoir is hydrocarbon bearing and is analogous to
reservoirs in the same area that are producing or have demonstrated the ability
to produce on formation tests.

The area of the reservoir considered as proved includes (1) the area delineated
by drilling and defined by fluid contacts, if any, and (2) the undrilled
portions of the reservoir that can reasonably be judged as commercially
productive on the basis of available geological and engineering data. In the
absence of data on fluid contacts, the lowest known occurrence of hydrocarbons
controls the proved limit unless otherwise indicated by definitive geological,
engineering or performance data.

<PAGE>   353

Reserves may be classified as proved if facilities to process and transport
those reserves to market are operational at the time of the estimate or there is
a reasonable expectation that such facilities will be installed. Reserves in
undeveloped locations may be classified as proved undeveloped provided (1) the
locations are direct offsets to wells that have indicated commercial production
in the objective formation, (2) it is reasonably certain such locations are
within the known proved productive limits of the objective formation, (3) the
locations conform to existing well spacing regulations where applicable, and (4)
it is reasonably certain the locations will be developed. Reserves from other
locations are categorized as proved undeveloped only where interpretations of
geological and engineering data from wells indicate with reasonable certainty
that the objective formation is laterally continuous and contains commercially
recoverable petroleum at locations beyond direct offsets.

Reserve which are to be produced through the application of established improved
recovery methods are included in the proved classification when (1) successful
testing by a pilot project or favorable response of an installed program in the
same or an analogous reservoir with similar rock and fluid properties provides
support for the analysis on which the project was based, and, (2) it is
reasonably certain that project will proceed. Reserves to be recovered by
improved recovery methods that have yet to be established through commercially
successful applications are included in the proved classification only (1) after
a favorable production response from the subject reservoir from either (a) a
representative pilot or (b) an installed program where the response provides
support for the analysis on which the project is based and (2) it is reasonably
certain the project will proceed.

UNPROVED RESERVES

Unproved reserves are based on geologic and/or engineering data similar to that
used in estimates of proved reserves; but technical, contractual, economic, or
regulatory uncertainties preclude such reserves being classified as proved.
Unproved reserves may be further classified as probable reserves and possible
reserves.

Unproved reserves may be estimated assuming future economic conditions different
from those prevailing at the time of the estimate. The effect of possible future
improvements in economic conditions and technological developments can be
expressed by allocating appropriate quantities of reserves to the probable and
possible classifications.

PROBABLE RESERVES

Probable reserves are those unproved reserves which analysis of geological and
engineering data suggests are more likely than not to be recoverable. In this
context, when probabilistic methods are used, there should be a least a 50%
probability that the quantities actually recovered will equal or exceed the sum
of estimated proved plus probable reserves.

In general, probable reserves may include (1) reserves anticipated to be proved
by normal step-out drilling where subsurface control is inadequate to classify
these reserves as proved, (2) reserves in formations that appear to be
productive based on well log characteristics but lack core data or definitive
tests and which are not analogous to producing or proved reservoirs in the area,
(3) incremental reserves attributable to infill drilling that could have been
classified as proved if closer statutory spacing had been approved at the time
of the estimate, (4) reserves attributable to improved recovery methods that
have been established by repeated commercially successful applications when (a)
a project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir characteristics appear favorable for commercial application, (5)
reserves in an area of the formation that appears to be separated from the
proved area by faulting and the geologic interpretation indicates the subject
area is structurally higher than the proved area, (6) reserves attributable to a
future workover, treatment, re-treatment, change of equipment, or other
mechanical procedures, where such procedure has not been proved successful in
wells which exhibit similar behavior in analogous reservoirs, and (7) 
incremental reserves in proved reservoirs where an alternative interpretation of
performance or volumetric data indicates more reserves than can be classified as
proved.

POSSIBLE RESERVES

Possible reserves are those unproved reserves which analysis of geological and
engineering data suggests are less likely to be recoverable than probable
reserves. In this context, when probabilistic methods are used, there should be
a least a 10% probability that the quantities actually recovered will equal or
exceed the sum of estimated proved plus probable plus possible reserves.

In general, possible reserves may include (1) reserves which, based on
geological interpretations, could possibly exist beyond areas classified as
probable, (2) reserves in formations that appear to be petroleum bearing based
on log and core analysis but may not be productive at commercial rates, (3)
incremental reserves attributed to infill drilling that are subject to technical
uncertainty, (4) reserves attributed to improved recovery methods when (a) a
project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir

<PAGE>   354

characteristics are such that a reasonable doubt exists that the project will be
commercial, and (5) reserves in an area of the formation that appears to be
separated from the proved area by faulting and geological interpretation
indicates the subject area is structurally lower than the proved area.

RESERVE STATUS CATEGORIES

Reserve status categories define the development and producing status of wells
and reservoirs.

     DEVELOPED: Developed reserves are expected to be recovered from existing
     wells including reserves behind pipe. Improved recovery reserves are
     considered developed only after the necessary equipment has been installed,
     or when the costs to do so are relatively minor. Developed reserves may be
     sub-categorized as producing or non-producing.

         PRODUCING: Reserves subcategorized as producing are expected to be
         recovered from completion intervals which are open and producing at the
         time of the estimate. Improved recovery reserves are considered
         producing only after the improved recovery project is in operation.

         NON-PRODUCING. Reserves subcategorized as non-producing include shut-in
         and behind-pipe reserves. Shut-in reserves are expected to be recovered
         from (1) completion intervals which are open at the time of the
         estimate but which have not started producing, (2) wells which were
         shut-in for market conditions or pipeline connections (3) wells not
         capable of production for mechanical reasons. Behind-pipe reserves are
         expected to be recovered from zones in existing wells, which will
         require additional completion work or future recompletion prior to the
         start of production.

     UNDEVELOPED RESERVES: Undeveloped reserves are expected to be recovered:
     (1) from new wells on undrilled acreage, (2) from deepening existing wells
     to a different reservoir, or (3) where a relatively large expenditure is
     required to (a) recomplete an existing well or (b) install production or
     transportation facilities for primary or improved recovery projects.

ATTENTION:       SPECIAL TRANSACTIONS COMMITTEE
                 SWIFT ENERGY COMPANY BOARD OF DIRECTORS

At the request of SWIFT ENERGY COMPANY (SWIFT), J. R. BUTLER AND COMPANY
(JRBCO) has conducted an evaluation audit of the hydrocarbon reserves and
future net cash flow as of December 31, 1997, associated with 44 Acquisition
Programs located in the U.S.A.  From this audit, and in consultation with H. J.
Gruy and Associates, Inc. (Gruy), JRBCO has generated its opinion of a "fair
market value" for these properties.  The market values of the properties were
distributed to various partnerships based on ownership to determine the fair
market value of each partnership. In JRBCO'S opinion, utilizing the
distribution of properties into the proper partnerships, the estimated market
value of SWIFT ENERGY PENSION PARTNERS 1993-B, LTD. is $1,234,678.

Proved reserves in this instance are defined as those estimated volumes of
crude oil, condensate, natural gas, and natural gas liquids that geological and
engineering data demonstrate with reasonable certainty to be commercially
recoverable in the future from known reservoirs under a reasonable price and
cost escalation scenario.  Probable reserves are the estimated quantities of
commercially recoverable hydrocarbons associated with known accumulations which
are based on engineering and geological data similar to those used in the
estimates of proved reserves but, for various reasons, these data lack the
certainty required to classify the reserves as proved.  Possible reserves are
the estimated quantities of commercially recoverable hydrocarbons associated
with known accumulations, which are based on engineering and geological data
which are less complete and less conclusive than the data used in estimates of
probable reserves.  In some cases, economic or regulatory uncertainties may
dictate a probable or possible classification.

Recovery of proved reserves is not without risk but, as generally considered in
the industry, the risk of recovering probable reserves is substantially greater
than that associated with proved categories.  Likewise, possible reserves are
less certain to be recovered than probable.

The reserves and future performance estimates were prepared utilizing standard
petroleum engineering methods.  For properties with sufficient production
history,





                                       1
<PAGE>   356
reserves estimates and rate projections were based primarily on extrapolation
of established performance trends and reconciled, whenever possible, with
volumetric and/or material balance calculations.  For the non-producing zones
and undeveloped locations, reserves were determined by a combination of
volumetric calculations and analogy.  Volumetrically determined reserves or
those determined by analogy are generally subject to greater qualifications
than reserves estimates supported by established production decline curves
and/or material balance calculations.  Determination and classification of
proved reserves were performed (with exception of the use of escalated prices
and costs) in accordance with Securities and Exchange Commission guidelines.
The definitions used also conform to those promulgated by the Society of
Petroleum Engineers (SPE) and the World Petroleum Congresses (WPC).

The reserves and resulting "value estimates" included  in this study are not
exact quantities.  Future conditions may affect the recovery of estimated
reserves, revenue and net cash flow, and all categories of reserves may be
subject to revision and/or reclassification as more performance and well data
become available.  Please note, the reserves estimates made by JRBCO were done
in conjuction with an evaluation audit and are not the result of in-depth field
studies.  In conducting this audit JRBCO reviewed approximately 65% of SWIFT'S
proved "PV 10  value" (SEC PV10 as of December 31, 1997) for the total 44
Acquisition Programs.

Basic evaluation data were obtained principally from SWIFT and public sources.
The production data available to JRBCO were generally through  August 1997.
Gas and liquid prices were year end (CY 1997) prices as used in SWIFT'S
December 31, 1997, SEC cash flow runs.

Estimates of drilling, completion and workover costs were based on information
supplied by SWIFT.  Operating costs were also based on data supplied by SWIFT
in their Lease Operating Statement which was reviewed by JRBCO.  Surface and
well equipment salvage values and well plugging and field abandonment costs
were not considered in the revenue projections.

The estimates of future net cash flow used in market value calculations are
those revenues which should be realized from the sale of the estimated reserves
after deduction of royalties, ad valorem and production taxes, direct operating
costs and required capital expenditures, when applicable.  Future net cash flow
as used in this evaluation is before the deduction of federal income tax.

Market value estimates were obtained by applying qualitative risk adjustments
considered appropriate for the various reserves categories and "profit factors"
(as applicable) against discounted future net cash flow values obtained from an
escalated cost and pricing scenario.  Prices, costs and investments were
escalated at 3.5%/year for 15 years.  Final market value estimates were derived
in conjunction and consultation with Gruy.

In the conduct of our review, we have not independently verified the accuracy
and completeness of information and data furnished by SWIFT with respect to
ownership interests, oil and gas production volumes and rates, historical costs
of operation and development, product prices, agreements relating to current
and future operations and sales of production and other information relative to
such things as timing or scheduling of drilling or recompletion operations.

Field inspections were not made in connection with the preparation of this
report.  Furthermore, no judgments were made relative to environmental or other
legal liabilities.

It should be recognized that any oil or gas reserves estimate or forecast of
production and income is a function of engineering and geological
interpretation and judgment.  Such estimates should, therefore, be accepted and
used with the understanding that technical data, economic criteria or
regulatory information obtained subsequent to a study may justify revisions
which could increase or decrease the original estimates of reserves and value.

Neither JRBCO, nor any of its personnel, have any direct or indirect interest
in SWIFT or its affiliates.  JRBCO is an independent consulting firm as
provided in the Standards Pertaining to the Estimating and Auditing of Oil and
Gas Reserves Information promulgated by the Society of Petroleum Engineers.

 JRBCO'S compensation is not contingent upon the results of its reserves
estimates, cash flow analyses or "market value opinion" which result from its
review of the subject properties.

Houston, TX  77060

Attention:        Special Transactions Committee
                  Swift Energy Company Board of Directors

Gentlemen:

Pursuant to that certain letter agreement dated February 27, 1998 (the
"Agreement") between the Special Transactions Committee (the "Committee") of the
Board of Directors of Swift Energy Company ("Swift" or the "Company") and CIBC
Oppenheimer Corp. ("CIBC Oppenheimer"), you have retained CIBC Oppenheimer to
prepare an independent financial analysis as to the estimated fair market value
(the "CIBC Oppenheimer Valuation") of various interests (the "Assets") in oil
and gas properties (the "Properties'), which Assets are owned by Swift Energy
Pension Partners 1993-B Ltd. (the "Partnership") of which the Company is the
managing general partner ("General Partner"). CIBC Oppenheimer performed a
similar analysis for 62 other partnerships (the "Partnerships") of which the
Company is the General Partner. It is CIBC Oppenheimer's understanding that the
General Partner has proposed to purchase substantially all of the Partnership's
Assets and, in turn, dissolve and wind up the Partnership. It is also CIBC
Oppenheimer's understanding that the Committee has also retained the reserve
engineering firms of H.J. Gruy & Associates, Inc. and J.R. Butler & Company
(collectively, the "Engineering Consultants") to prepare a separate analysis as
to the estimated fair market value of the Assets (the "Engineering Consultants'
Valuation").

In arriving at the CIBC Oppenheimer Valuation, we, among other things:

         (i)      Reviewed the historical financial returns to the limited 
                  partners of the Partnership;

         (ii)     Held discussions with senior management of the Company as to 
                  the Partnership's operational and financial prospects;




<PAGE>   359

         (iii)    Held discussions with senior management of the Company 
                  regarding the general characteristics of the Properties
                  underlying the Assets, including location, productive
                  geological formations, future development potential and oil
                  and gas marketing arrangements;

         (iv)     Held discussions with the Engineering Consultants regarding
                  the general characteristics of the Properties underlying the
                  Assets, including location, productive geological formations
                  and future development potential;

         (v)      Reviewed the reserve engineering reports supplied to us by the
                  Engineering Consultants and, particularly, reviewed the
                  estimated future net cash flow to be generated from the
                  production of proved reserves of the Properties underlying the
                  Assets discounted to present value using an annual discount
                  rate of 10% (the "PV-10 Value") dated as of December 31, 1997;
                  these amounts were 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 future
                  income tax expense or depreciation, depletion and
                  amortization;

         (vi)     Reviewed the Engineering Consultants' Valuation of the 
                  Properties underlying the Assets;

         (vii)    Reviewed historical operating and financial results of the
                  Properties underlying the Assets which included PV-10 Value,
                  proved reserves on a barrel of oil equivalent ("BOE") basis
                  and projected earnings before interest, taxes and
                  depreciation, depletion and amortization ("EBITDA") as
                  prepared by the Engineering Consultants and discussed with
                  senior management of the Company;

         (viii)   Reviewed and analyzed financial terms of similar transactions
                  in which public oil and gas companies liquidated partnerships
                  of which they were the general partner;

         (ix)     Reviewed and analyzed transactions involving the sale of oil
                  and gas companies we deemed comparable to the Partnership(s)
                  individually and collectively and to the Company;

         (x)      Reviewed and analyzed transactions involving the sale of oil 
                  and gas properties we deemed comparable to the Properties
                  underlying the Assets;

         (xi)     Reviewed financial and market data for certain public
                  companies we deemed comparable to the Partnership(s)
                  individually and collectively and to the Company; and

         (xii)    Performed such other analyses and reviewed such other
                  information as we deemed appropriate.

In determining the CIBC Oppenheimer Valuation, we have relied upon and assumed,
without independent verification or investigation and at the direction of the
Committee, (i) the accuracy and completeness of all of the financial and other
information available to us from public sources or provided to us by the Company
and their representatives (including the Engineering Consultants), (ii) that the
reserve engineering reports supplied to us by the Engineering Consultants as
described in clause (v) above have been reasonably prepared and are based on
their best business judgment, (iii) that the information with respect to the
Partnership's ownership of the Assets, as provided to the Engineering
Consultants and to us was accurate in all respects, (iv) with respect to the
historical operating and financial results and projections provided to us as
described in clause and (vii) above, that such information and projections were
reasonably prepared and were based on the best currently available information,
estimates and good faith judgment of the Company's management and their
representatives (including the Engineering Consultants).

Not being experts in the geological evaluation of oil and gas reserves, we have,
with your consent, relied without independent verification upon the audit of the
reserve estimates prepared by the Engineering Consultants for the purpose of
estimating fair market value of the Assets. In addition, we have not made a
physical inspection of the Properties underlying the Assets, nor have we made
any independent evaluations, appraisals or inspections of the Company's or the
Partnership's other assets or the Company's or the Partnership's liabilities
(contingent or otherwise). We have not reviewed any relevant agreements which
may exist between the General Partner and the limited partners governing the
Partnership, nor have we considered the effect which the ownership structure of
the Partnership and the terms of the agreements of the Partnership may have upon
the fairness of the consideration offered by any general partner of the
Partnership. We have not reviewed the books and records of the Partnership and
have assumed, with your consent, that the Partnership's ownership interests in
the Properties underlying the Assets, as provided to us by you, is true and
correct.

The CIBC Oppenheimer Valuation is based upon analyses of the foregoing factors
in light of our assessment of general economic, financial, market and other
conditions and circumstances as of the date of this letter and any changes in
such conditions and circumstances may affect the validity or fairness of the
CIBC Oppenheimer Valuation. CIBC Oppenheimer disclaims any obligations to
update, revise or reaffirm the CIBC Oppenheimer Valuation. The CIBC Oppenheimer
Valuation reflects our estimate of the consideration that could have been
received by the Partnership in a sale of the Assets in an orderly manner in a
private market transaction in which neither buyer nor seller is under any
compunction to complete such transaction. The CIBC Oppenheimer Valuation falls
within a range of values which we believe, subject to the foregoing conditions,
represent possible fair market value estimates of the Partnership's interest in
the Assets. The CIBC Oppenheimer Valuation should not be viewed as a guarantee
of the price that a willing buyer might have paid for the Assets.

CIBC Oppenheimer, as part of its investment banking services, is regularly
engaged in the valuation of businesses and securities in connection with
mergers, acquisitions, underwritings, sales and distributions of listed and
unlisted securities and private placements. CIBC Oppenheimer has provided
certain investment banking and financial advisory services to the Company from
time to time, including acting as co-manager of the Company's Convertible
Subordinated Notes financing in November 1996 and lead manager of the public
offering of the Company's Common Stock in July 1995, and may be involved in
future investment banking activities on behalf of the Company. CIBC Oppenheimer
will also receive a fee upon delivery of this CIBC Oppenheimer Valuation. In the
ordinary course of business, CIBC Oppenheimer actively trades in the equity
securities of the Company for CIBC Oppenheimer's own account and for the
accounts of CIBC Oppenheimer's customers and, accordingly, may at any time hold
a long or short position in such securities.

Based upon and subject to the foregoing, and based upon such other matters as we
consider relevant, it is CIBC Oppenheimer's estimate that the value of Swift
Energy Pension Partners 1993-B Ltd. interest in the Assets as of the date hereof
is $1,327,783.

This letter is being provided for the use of the Committee in its evaluation of
a possible proposal that the Partnership sell the Assets to the Managing General
Partner and dissolve and wind up its affairs. This letter is not intended to
confer rights or remedies upon any stockholder of the Company or any partner of
the Partnership and may not be relied upon by any person or entity other than
the Committee. Neither this letter nor the CIBC Oppenheimer Valuation may be
published or otherwise used or referred to, in whole or

part, nor shall any public reference to CIBC Oppenheimer, this letter or the
CIBC Oppenheimer Valuation be made without the prior written consent of CIBC
Oppenheimer; provided, however, that the Company and the Partnership may include
a copy of this letter and a reference to CIBC Oppenheimer in the proxy statement
to be distributed to limited partners of the Partnership in connection with the
solicitation of the approval of the proposal that the Partnership sell the
Assets to the General Partner and dissolve and wind up its affairs. Neither this
letter nor the CIBC Oppenheimer Valuation constitutes a recommendation to any
partner of the Partnership as to how such partner should vote on or respond to
the proposal that the Partnership sell the Assets to the General Partner and
dissolve and wind up its affairs.

Gentlemen:

At your request, we have made an audit of the reserves and future net cash flow
as of December 31, 1997, prepared by Swift Energy Company ("Swift") for certain
interests in Swift Energy Pension Partners 1993-B. This audit has been conducted
according to the standards pertaining to the estimating and auditing of oil and
gas reserve information approved by the Board of Directors of the Society of
Petroleum Engineers on October 30, 1979. We have reviewed these properties and
where we disagreed with the Swift reserve estimates, Swift revised its estimates
to be in agreement. The estimated net reserves, future net cash flow and
discounted future net cash flow are summarized by reserve category in Table 1
for both the 100% Fund Level Partnership and the Limited Partnership Interest.

The discounted future net cash flow is not represented to be the fair market
value of these reserves and the estimated reserves included in this report have
not been adjusted for risk.

The estimated future net cash flow shown is that cash flow which will be
realized from the sale of the estimated net reserves after deduction of
royalties, ad valorem and production taxes, direct operating costs and required
capital expenditures, when applicable. Surface and well equipment salvage values
and well plugging and field abandonment costs have not been considered in the
cash flow projections. Future net cash flow as stated in this report is before
the deduction of state and federal income tax.

In the economic projections, prices, operating costs and development costs
remain constant for the projected life of each lease.

The reserves included in this study are estimates only and should not be
construed as exact quantities. Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available. Proved reserves are
estimated in accordance with the definitions contained in Securities and
Exchange Commission Regulation S-X, Rule 4-10(a). The definitions are included
in part as Attachment I.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented. The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December. Interim production to December 31, 1997, has been
estimated. No independent well tests, property inspections or audits of
operating expenses were conducted by our staff in conjunction with this study.
We did not verify or determine the extent, character, obligations, status or
liabilities, if any, arising from any current or possible future environmental
liabilities that might be applicable.

Swift Energy Company                    -2-                    February 10, 1998

In order to audit the reserves, costs and future net cash flows shown in this
report, we have relied in part on geological, engineering and economic data
furnished by our client. Although we have made a best efforts attempt to acquire
all pertinent data and to analyze it carefully with methods accepted by the
petroleum industry, there is no guarantee that the volumes of oil or gas or the
cash flows projected will be realized.

Production rates may be subject to regulation and contract provisions, and may
fluctuate according to market demand or other factors beyond the control of the
operator. The reserve and cash flow projections presented in this report may
require revision as additional data become available.

We are unrelated to Swift and we have no interest in the properties included in
the information reviewed by us. In particular:

         1.     We do not own a financial interest in Swift or its oil and gas
                properties.

         2.     Our fee is not contingent on the outcome of our work or report.

         3.     We have not performed other services for or have any other
                relationship with Swift that would affect our independence.

If investments or business decisions are to be made in reliance on these
estimates by anyone other than our client, such person with the approval of our
client is invited to visit our offices at his expense so that he can evaluate
the assumptions made and the completeness and extent of the data available on
which our estimates are based.

Any distribution or publication of this report or any part thereof must include
this letter in its entirety.

                                Yours very truly,

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                                   SUPPLEMENT

                              SWIFT ENERGY COMPANY


         For the definition of capitalized terms herein which are not otherwise
defined, see "Glossary" in the Joint Proxy Statement/Prospectus.  Other
discussions which are cross-referenced in this Supplement are contained in the
Joint Proxy Statement/Prospectus, unless otherwise noted.

         Swift Energy Company ("Swift" or the "Company") is the Managing
General Partner ("Managing General Partner") of 63 Texas limited partnerships
(the "Partnerships"), including the Partnership, formed between 1986 and 1994
to invest in producing oil and gas properties.  Swift is asking limited
partners (referred to herein as "Investors") in the Partnership (and similarly
in the other 62 Partnerships) to approve a Proposal to sell all of the
Partnership's oil and gas assets to the Managing General Partner (the
"Proposal") for $1,684,539, which is a purchase price derived by choosing the
higher of two estimates of fair market value of those assets determined by
three independent Appraisers, and adding to that higher number a 7.5% premium.

         If the Proposal is approved by Investors in the Partnership, after the
sale of all of its oil and gas assets the Partnership will dissolve, wind up
and terminate.  The Partnership will receive cash for its oil and gas assets,
which in turn is to be distributed to the Investors in the Partnership (along
with the net of all assets less liabilities of the Partnership) in accordance
with their respective percentage ownership interests in the Partnership.  If
Investors in the Partnership approve the Proposal, then each Investor can
elect, in their sole individual discretion, to receive shares of Common Stock
of the Company (without payment of any brokerage commissions) instead of some
or all of the cash which they are entitled to receive upon the Partnership's
liquidation.

         The reasons for and effects of the Proposals may be different for
investors in each of the Partnerships.  This Supplement has been prepared to
highlight for the Investors in the Partnership the particular risks, effects
and fairness of the Proposal to the Investors in the Partnership and to provide
information on the Partnership to its Investors, in connection with the
solicitation of proxies by the
<PAGE>   369
Managing General Partner for use at the Special Meeting of the Investors in the
Partnership in voting upon the Proposal and to transact such other business as
may be properly presented at the Special Meeting or any adjournments or
postponements thereof.

         BOTH THE VOTE UPON THE PROPOSAL AND ANY ELECTION MADE BY AN INDIVIDUAL
INVESTOR TO RECEIVE SHARES OF SWIFT ENERGY COMPANY COMMON STOCK ARE SUBJECT TO
NUMEROUS RISK FACTORS, INCLUDING THOSE HIGHLIGHTED BELOW.  SEE "RISK FACTORS"
IN THIS SUPPLEMENT AND IN THE JOINT PROXY STATEMENT/PROSPECTUS FOR A FULL
DISCUSSION OF ALL RISK FACTORS.

o        Substantial conflicts of interest exist because if the Proposal is
         approved by the Partnership, the Managing General Partner will
         purchase all of the oil and gas assets from the Partnership while it
         serves as its Managing General Partner.

o        The purchase price for the Partnership's Property Interests may not be
         the highest possible price.

o        No independent representative negotiated the terms of the purchase
         price with the Managing General Partner.

o        No fairness opinion was acquired regarding the fairness of the
         purchase price.

o        The Managing General Partner may profit from acquisition of the
         Partnership's oil and gas assets by investing capital in order to
         develop non-producing reserves of the acquired Property Interests and
         possibly through improvement in oil and gas prices.

o        Estimates of distributions to Investors from continuing operations of
         the Partnership for the life of its reserves are higher than amounts
         anticipated to be received if Investors vote in favor of the Proposal.
         See "Special Factors--Fairness of Proposal of Sale of Assets as
         Compared to Continuing Operations."

o        An election by an Investor to receive shares of Swift Common Stock in
         lieu of cash distributable to Investors subjects such Investors to the
         risks of investing in the Company.

                 This Supplement is dated ______________, 1998

                                THE PARTNERSHIP

         The Partnership was formed over eleven years ago and owns working
interests in producing oil and gas properties in two states.  The Partnership
had expended all of its original capital contributions by the end of December
1987.  The Partnership's oil and gas properties are principally natural gas
properties, representing approximately 78% of the Partnership's 1997 production
and approximately 81% of its total proved reserves at December 31, 1997.  From
time to time, the Partnership has performed workovers and recompletions on
wells in which the Partnership has working interests, using funds advanced by
the Managing General Partner or third parties, to perform these operations,
which amounts have been subsequently repaid.  The Partnership owns interest in
128 wells in six fields.

         The following table presents information on those fields in which the
Partnership has Property Interests which constitute 10% or more of the
Partnership's PV-10 Value at December 31, 1997.  The Partnership's "PV-10
Value" is the estimated future net cash flows (using unescalated prices) from
production of proved reserves attributed to the Partnership's Property
Interests, discounted to present value at 10% per annum.  Attachment D to this
Supplement is the report dated February 10, 1998 of the audit by H.J. Gruy and
Associates, Inc., Independent Petroleum Consultants, of the oil and gas
reserves underlying the Partnership's Property Interests, and future net cash
flow expected from the production of those reserves as of December 31, 1997,
presented both for the Partnership as a whole and as to those reserves solely
attributable to the Investors in the Partnership.  This report has not been
updated to include the effect of production since year-end 1997.  In estimating
these reserves, the Managing General Partner, in accordance with criteria
prescribed by the Securities and Exchange Commission, has used year-end 1997
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.  The Managing General
Partner is not aware of any favorable or adverse event causing a significant
change in the estimated amount (as set forth in Attachment D hereto, which is
the report of H.J. Gruy and Associates, Inc.) of proved reserves of the
properties in which the Partnership owns an interest has occurred between
December 31, 1997 and the date of this Supplement.

         The information below includes the location of each field in which the
Partnership has an interest, the number of wells and operators, together with
information on the percentage of the Partnership's total PV-10 Value on
December 31, 1997 attributable to each of these fields.  Information is also
provided regarding the percentage of the Partnership's 1997 production (on a
volumetric basis) from each of these fields.  Of the remaining other fields in
which the Partnership owns a Property Interest, two of such fields each
comprise less than 1% of the Partnership's PV-10 Value at December 31, 1997,
and the PV-10 Value of each of the other two fields averages less than 8% of
the Partnership's PV- 10 Value at the same date.

_________________
         (1) Proved producing reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
         (2) Behind-pipe reserves are proved reserves that will not contribute 
to cash flows until recompletion projects have been implemented to place them
into production.  The impact of these recompletion projects will also be limited
until the costs of implementation have been recovered.  In general, it is not
appropriate to bring behind-pipe reserves into production until the formation
that is currently producing has been depleted.  Premature recompletions can lead
to permanent reductions in a well's proved reserves.
        
         (3) Non-developed reserves are reserves that are expected to be 
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion.  Therefore,
significant additional expenditures are usually required before undeveloped
reserves can be produced.
        
         Attachment Dis the annual reserves audit and independent reserves
report prepared by H.J. Gruy and Associates, Inc. as to the Partnership's
remaining proved oil and gas reserves available for production over a period in
excess of 15 years.  These quantities have been given a value based upon prices
for oil and gas at December 31, 1997.  The value is determined based upon the
assumption that these prices will remain in effect over the life of these
reserves.  This value is then discounted at 10% per year to arrive at the value
(in today's dollars) of these revenues ("PV-10 Value").  This PV-10 Value for
the Partnership's Property Interests is $2,327,010.  It is also estimated that
$366,621 in future capital costs must be spent to develop the Partnership's
non-producing reserves.

                                  RISK FACTORS

o        Although the fair market value of the Property Interests proposed to
         be purchased from the Partnership by the Managing General Partner was
         based upon a determination by three independent Appraisers, no opinion
         was acquired as to the fairness of the ultimate purchase price, which
         was determined in the Managing General Partner's sole judgment by
         adding a 7.5% premium over the higher of the two fair market value
         estimates for the Partnership's Property Interests determined by the
         Appraisers.  Therefore, the purchase price was not determined on an
         impartial basis by a party not involved in the transaction, and
         another party intent upon purchasing the Property Interests in the
         Partnership might have offered a different purchase price.  There is
         no guarantee that the purchase price represents the highest possible
         price that could be received for the Partnership's Property Interests
         in all circumstances.  It is possible that a higher (or lower) price
         might be received if these assets were sold on another basis, such as
         at auction or in negotiated sales.  Furthermore, the assessment of the
         value of the Partnership's proved non-producing reserves could vary
         widely, given the typical discounting in valuing non-producing
         reserves.

o        The Managing General Partner did not retain an independent
         representative to act on behalf of the Investors in the Partnership in
         structuring and negotiating the terms or price of the Proposal or the
         purchase price.  The price at which it is proposed that the Company
         purchase the Property Interests from the Partnership has not been
         negotiated at arm's length and is subject to significant conflicts of
         interest between the Company acting as the purchaser of such
         properties while serving as the Managing General Partner of the
         Partnership.  If an independent representative had been retained for
         the Partnership, the terms or price might have been different and
         possibly more favorable to Investors.

o        The fair market value (excluding the 7.5% premium) established for the
         Partnership's Property Interests is based upon the Appraisers'
         evaluation of that value.  Year-end 1997 prices, along with other
         current market factors, were used as a starting point for the
         Appraisers' analysis, and prices and costs were then escalated at a
         rate of 3.5% per year over 15 years.  Substantial increases in the
         prices for oil and gas in the future might result in Investors
         receiving higher distributions from continued operations of the
         Partnership, although the effect of any higher prices is somewhat
         limited because the Partnership has already produced a substantial
         majority of its oil and gas reserves.

o        A majority of the Partnership's proved oil and gas reserves are
         non-producing.  Because non-producing reserves are traditionally
         discounted due to future costs which must be incurred to recover those
         reserves and the risk that any drilling will be unsuccessful, there is
         a risk that the discount applied to the non-producing reserves by the
         Petroleum Engineering Consultants could be greater than the discount
         applied by a third party purchaser.  Likewise, it is likely that any
         drilling conducted on Property Interests acquired from the Partnership
         has upside potential, the benefit of which will go to the Managing
         General Partner if it acquires those properties.


o        Investors that are subject to federal income tax on an investment in
         the Partnership are required to recognize gain or loss on the sale of
         oil and gas assets by the Partnership and the subsequent liquidation
         of the Partnership.  The amount and character of the gain or loss
         depends on certain factors specific to individual Investors.  It is
         anticipated that Investors that acquired their interests





                                       5
<PAGE>   373
         in the original offering will recognize a gain for federal income tax
         purposes.  Any tax that may be due must be paid even if such Investors
         choose to acquire Company Common Stock with some or all of their
         proceeds from property sales.  Investors also should consult their
         individual tax advisors to determine whether they are subject to any
         state tax.  For a broader discussion of the tax consequences,
         Investors should read "Federal Income Tax Consequences of Adoption of
         the Proposals" in the Joint Proxy Statement/Prospectus and "Summary of
         Federal Income Tax Consequences" in this Supplement.

o        Investors that are Tax Exempt Plans will be subject to taxation on the
         Partnership's sale of property and the liquidation of the Partnership,
         while other Tax Exempt Plans are not expected to be subject to
         taxation on the sale and liquidation.  See "Summary of Federal Income
         Tax Consequences--Tax Treatment of Tax Exempt Plans--Debt-Financed
         Property" in this Supplement.

o        As currently proposed, Investors that subscribe for Company Common
         Stock pursuant to this Offering may not receive some or all of the
         cash which otherwise would be distributed to them as part of the
         liquidating distribution of their Partnership.  The amount of any cash
         liquidating distribution they actually receive depends upon the
         purchase price to be paid for any Company Common Stock they elect to
         and are entitled to receive pursuant to the terms of this Offering.
         For federal income tax purposes, Investors subscribing for shares of
         Company Common Stock will be treated as though they had purchased
         those shares for cash, even though they never had actual possession of
         the cash used to acquire the shares.  Additionally, the fact that such
         Investors elect to acquire Company Common Stock rather than receive
         cash in liquidation of their Partnership interests will not affect the
         federal income tax consequences attending the liquidation of their
         Partnership interests.  Because the purchase of shares of Company
         Common Stock will reduce the cash received by Investors upon the
         Partnership's liquidation, to the extent that Investors owe federal
         income tax as a result of the liquidation, they may not receive
         sufficient cash to pay some or all of any tax they may owe on the
         liquidation.  Such Investors owing tax as a result of the liquidation
         will have to pay such tax from sources other than any cash liquidating
         distribution from the Partnership.

See "Risk Factors" in the Joint Proxy Statement/Prospectus.

                             CONFLICTS OF INTEREST

         There are substantial conflicts of interest which exist by virtue of
the Managing General Partner acting in that capacity on behalf of the
Partnership while at the same time acting as the proposed purchaser of all of
the oil and gas assets of the Partnership.  These conflicts of interest are
discussed below.

o        The terms of the Proposal are established by the Company which is also
         the Managing General Partner of the Partnership.

o        Neither the Managing General Partner nor a majority of its independent
         directors retained an independent representative to act on behalf of
         the Partnership's Investors for the purposes of negotiating the terms
         upon which any such sale to the Managing General Partner would be made
         or for the preparation of a report concerning the fairness of the
         entire transaction.

See "Summary--Conflicts of Interest" and "Conflicts of Interests" in the Joint
Proxy Statement/Prospectus.

                                SPECIAL FACTORS

BACKGROUND AND PURPOSE OF THE PROPOSAL

         A number of factors have led to the decision of the Company in its
capacity as Managing  General Partner to solicit approval of the Proposal by
Investors in the Partnership.  As contemplated when the Partnership was
organized, and given the expenditure of virtually all of the Partnership's
capital to purchase producing properties over ten years ago, the production
from Partnership oil and gas assets declined over time.  It was always
anticipated that a time would arrive when the Managing General Partner would
propose that the business of the Partnership be concluded, its assets sold or
otherwise disposed of and the Partnership liquidated and dissolved.  The
general improvement in the prices for natural gas over the last several years,
relative to such prices in the mid-1990's, make this an appropriate time,
especially in light of the age of the Partnership and the high percentage of
its reserves comprised of natural gas, to consider the Proposal to sell the
Partnership's Property Interests.  The structure being proposed, which involves
the sale of the Partnership's oil and gas assets to the Managing General
Partner, is being submitted for approval by Investors in an attempt to realize
the highest value for those assets.  For the reasons set out below, the
Managing General Partner believes that the Proposal is fair to Investors in the
Partnership, given that the purchase price for these assets has been determined
by taking the higher of two fair market value estimates by three independent
Appraisers and adding to it a 7.5% premium.

         Approval of the Proposal will have the following effects:

1.       The Managing General Partner will purchase all of the oil and gas
         assets of the Partnership.

2.       When the Partnership sells all of its oil and gas assets, it will be
         required to liquidate and distribute its remaining assets (principally
         the cash proceeds from the sale) to its partners (including the
         general partners) in accordance with their respective ownership
         interests in the Partnership.

3.       Investors will be given the option of electing to receive shares of
         Swift Common Stock, in amounts that they choose on an individual
         basis, in lieu of some or all of the cash they would be entitled to
         receive upon the Partnership's liquidation.

4.       The Managing General Partner may spend capital to develop
         non-producing reserves on properties which it acquires from the
         Partnership, although the properties in which such investment will be
         made have not yet been determined.

5.       Investors in the Partnership will be taxed on the sale of the
         Partnership's oil and gas assets, although such sale is expected to
         result in a taxable gain to Investors that acquired their interests in
         the original offering.

PROPOSED PURCHASE PRICE

         As discussed in greater detail below, the Petroleum Engineering
Consultants estimated that the aggregate fair market value of the Partnership's
Property Interests as of December 31, 1997 is $1,567,013.  CIBC Oppenheimer
estimated a fair market value of the same Property Interests at the same date
of $1,369,233.  The Special Transactions Committee chose the higher of these
two determinations as the "Fair Market Value" for the purchase of these
interests and the Board of Directors of the Company determined





                                       7
<PAGE>   375
to pay a 7.5% premium ($117,526) above the Fair Market Value to purchase the
Partnership's Property Interests, resulting in a purchase price of $1,684,539.
This compares to the total purchase price for all of the oil and gas assets of
all 63 Partnerships which are considering similar proposals of approximately
$81 million.  The valuation estimates of the Appraisers are attached to this
Supplement and incorporated herein by reference as follows:  Attachment A is
the fair market value estimate of H.J. Gruy and Associates, Inc., Attachment B
is the fair market value estimate of J.R. Butler and Company, and Attachment C
is the fair market value estimate of CIBC Oppenheimer Corp.  The PV-10 Value
prepared on an annual basis by H.J. Gruy of the same Property Interests as of
the same date is $2,327,010.

REASONS FOR THE PROPOSAL

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

         Current Liquidating Distribution Lowers Volatility Risk.  The
Partnership has been in existence for over eleven years.  The Managing General
Partner believes that the ability to receive the estimated liquidating
distribution in one lump sum at this time, rather than in smaller amounts over
a longer period, is one of the benefits of the Proposal, without the risk of
such distributions being negatively affected by oil and gas price decreases and
the inherent risks associated with geological, engineering and operational
matters.  It is also the Managing General Partner's belief that improvements
over the last several years in the level of gas prices, relative to such prices
in the mid-1990's, makes 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 future prices and market volatility
cannot be predicted with any accuracy.

         Decreasing Cash Flow While Expenses Continue.  As of December 31,
1997, approximately  78% of the Partnership's ultimate recoverable reserves had
been produced.  As a result of such 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.  The
Partnership's oil and gas reserves are expected to continue to decline as
remaining reserves are produced.  Declines in well production are based
principally upon the maturity of the wells, not on market factors.  These
declines will continue to occur while oil field overhead and operating costs
($34,766 in 1997) and direct and general and administrative expenses ($98,342
in 1997) continue, which are relatively fixed amounts.  Each producing well
requires a certain amount of operating and other costs, which 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.  By accelerating the liquidation of the
Partnership, those future administrative costs will be avoided by the
Partnership.

         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 particularly gas prices that occurred subsequent to the
purchase of the Partnership's Property Interests.  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 1997 year-end reserve
calculations, the Partnership had only about 22% of its ultimate recoverable
reserves 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 material positive impact





                                       8
<PAGE>   376
on the total return on investment to Investors in view of the expenses of the
Partnership as described above.  Approximately 78% of the Partnership's 1997
production and approximately 81% of its total proved reserves at year-end 1997
were comprised of natural gas.  As of the summer of 1998, oil prices are
significantly lower than those for natural gas.  Historically when there has
been significant difference between the price of gas and oil, those prices have
adjusted to become reasonably equivalent.  Consequently, there may be a benefit
in selling the Partnership's Property Interests at this time and avoiding any
future decreases in prices of natural gas, although the direction and severity
of adjustments in prices for gas and/or oil are impossible to predict.

         Behind-Pipe Reserves.  It is estimated that approximately 49% of the
remaining reserves attributable to properties in which the Partnership has an
interest are behind-pipe reserves, which are unlikely to be producible for many
years because behind-pipe reserves always require completion of a well in a
different producing zone which does not take place until production is depleted
from the currently producing zones.  Recovery in amounts great enough to
significantly impact the results of the Partnership's operations and the
ultimate cash distributions to partners can only occur with the investment of
new capital.  As provided in its Partnership Agreement, the Partnership
expended all of the Investors' net commitments for the acquisition of Property
Interests many years ago and it no longer has capital to invest.  No additional
development activities are contemplated by the Partnership on the properties in
which the Partnership has an interest.

         Limited Partners' Tax Reporting.  Each Investor will continue to have
an 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
Investors generally are unable to dispose of their Units.  See "Partnership
Business and Financial Condition--No Trading Market" in this Supplement.
Following the sale of the Partnership's Property Interests and dissolution of
the Partnership, Investors will realize gain or loss, or a combination of both,
under federal income tax laws.  See "Summary of Federal Income Tax
Consequences--Taxable Gain or Loss upon Sale of Properties" herein.
Thereafter, Investors will have no further tax reporting obligations with
respect to the Partnership.  The dissolution of the Partnership will also allow
Investors to take a capital loss deduction for syndication costs incurred in
connection with formation of the Partnership.   See "Summary of Federal Income
Tax Consequences--Liquidation of the Partnership" in this Supplement.

See "Summary--Background and Reasons for the Proposals," "--Purpose and Effect
of the Proposals," "--Reasons for the Proposals" and "--Managing General
Partner's Recommendations" in the Joint Proxy Statement/Prospectus.

COLLECTIVE ANALYSIS OF PURCHASE PRICE; PREMIUM OVER FAIR MARKET VALUE

         The Special Transactions Committee selected H.J. Gruy and Associates,
Inc. ("H.J. Gruy" or "Gruy"), J.R. Butler and Company ("J.R. Butler" or
"Butler"), which are both petroleum engineering consultants, and CIBC
Oppenheimer Corp.  ("CIBC Oppenheimer"), an investment banking firm, to
estimate the fair market value of the Property Interests of each of the
Partnerships.  Collectively, H.J. Gruy, J.R. Butler and CIBC Oppenheimer are
referred to herein as the "Appraisers," and H.J. Gruy and J.R. Butler together
are sometimes referred to herein as the "Petroleum Engineering Consultants."

         The following subsections of the "Special Factors" section of the
Joint Proxy Statement/Prospectus should be reviewed for information concerning
the selection and qualification of the Appraisers and the





                                       9
<PAGE>   377
parameters of the valuation estimates: "Independent Appraisal of the Fair
Market Value of Property Interests of the Partnerships," "Qualification of
Appraisers," and "Fair Market Value."

         The Petroleum Engineering Consultants arrived at a fair market
valuation estimate of the Partnership's Property Interests based upon appraisal
of the projected discounted cash flow from its various Property Interests.  On
the other hand, the investment banking firm of CIBC Oppenheimer made a
valuation estimate of the Partnership's Property Interests based upon the
application of multiple quantitative and qualitative factors.  The quantitative
factors include, among other things, a review of relevant valuation criteria
from comparable acquisitions of both oil and gas properties and companies that
are predominantly active in the oil and gas industry, and a review of valuation
criteria for relevant publicly traded oil and gas companies.

         The process used by the Petroleum Engineering Consultants in preparing
their valuation estimate is discussed at length in the Joint Proxy
Statement/Prospectus under "Special Factors--Valuation by Petroleum Engineering
Consultants." As described therein, the Petroleum Engineering Consultants
individually audited the estimate of present value of future net cash flows
from the 44 property groups in which Property Interests are owned by the
Partnerships to whom similar proposals are being made to sell all of their oil
and gas assets and liquidate their Partnerships.  The Partnership owns Property
Interests in four of these property groups.  The Petroleum Engineering
Consultants began their analysis based upon the year-end 1997 PV-10 Value of
each property audited by H.J. Gruy and together they re-evaluated reserve
quantities, projected operating costs and cash flows.  The present value of
this reserves analysis was then derived by escalating year-end 1997 prices
($2.38 per MMBtu and $16.00 per barrel before adjustments for Btu content for
gas and gravity variances for oil as well as transportation charges and
geographic location) and costs by 3.5% per year for 15 years.  This present
value was then adjusted for various individual field risks and risk adjustments
of proved non- producing reserves and proved undeveloped reserves.  The result
of this collective analysis by the Petroleum Consulting Engineers was their
estimation that the fair market value of Property Interests owned by the
Partnership was $1,567,013 as of December 31, 1997.

         The methodology used by CIBC Oppenheimer to prepare its valuation
estimate is discussed at length under "Special Factors--Valuation by CIBC
Oppenheimer" in the Joint Proxy Statement/Prospectus.  CIBC Oppenheimer's
evaluation of the Partnership's Property Interests began with the PV-10 Value
of each property group, as calculated by Swift and audited by H.J. Gruy, which
Gruy report dated February 10, 1998 is Attachment D to this Supplement.  CIBC
Oppenheimer then divided the property groups into two categories.  Those
property groups with reserves consisting primarily of proved developed
producing reserves were placed in the "Conventional Case" category.  Those
property groups with significant proved developed non-producing or undeveloped
reserves were placed in the "Non-Conventional Case" category.  The Partnership
has interests in property groups which were in both the "Conventional Case" and
"Non-Conventional Case" categories.  CIBC Oppenheimer then valued each property
group (including those groups in both the "Conventional Case" and
"Non-Conventional Case" categories) by applying the multiples discussed under
"Special Factors--Valuation by CIBC Oppenheimer--Valuation Multiples" in the
Joint Proxy Statement/Prospectus to each property group's PV-10 Value, proved
reserves on a BOE basis, and projected 1998 EBIDTA.  A separate set of
multiples was used for property groups in the Conventional Case category and
the Non-Conventional Case category, respectively.  This provided CIBC
Oppenheimer with three estimated values for each property group.  The average
of these three values yielded CIBC Oppenheimer's estimation of the fair market
value of each property group.  CIBC Oppenheimer then allocated the appropriate
portion of each property group's





                                       10
<PAGE>   378
estimated fair market value to the Partnership based upon the Partnership's
Property Interests in each property group.  The result of this analysis by CIBC
Oppenheimer was an estimation that the fair market value of the Partnership's
Property Interests was $1,369,233 on December 31, 1997.

         The Special Transactions Committee has determined that, in keeping
with the definition of Fair Market Value, the higher of these two estimations
of fair market value, or $1,567,013, represents the Fair Market Value of the
Partnership's Property Interests.  Accordingly, the fair market value
estimation of the Petroleum Consulting Engineers and the fair market value
determined by CIBC Oppenheimer were compared to each other and the higher of
the two was chosen as the Fair Market Value of the Property Interests owned by
the Partnership.  The variation between the fair market value estimate of the
Partnership's Property Interests prepared by the Petroleum Consulting
Engineers, on one hand, and CIBC Oppenheimer on the other was 14%.

DETERMINATION OF PREMIUM OVER FAIR MARKET VALUE BY THE COMPANY

         The Special Transactions Committee presented its recommendation to the
Board of Directors of the Company as to the Fair Market Value of the Property
Interests of the Partnership.  The Board of Directors of the Company then
determined that paying a 7.5% premium over the Fair Market Value of the
Partnership's Property Interests was appropriate and fair based upon the
factors and for the reasons discussed below.  Because the Company has served as
Managing General Partner of the Partnership for over eleven years, it is
intimately familiar with the Property Interests owned by the Partnership.  The
Managing General Partner believes that if the Property Interests were to be
sold to a third party purchaser that was not equally familiar with those
interests, it is likely that the purchaser would discount the purchase price to
account for that lack of familiarity and associated risks.  If these interests
are purchased by the Company, then the additional cost and personnel often
inherent in making a property acquisition are not required, because the files
and deed records already exist in the Company's lease and computer systems, and
conveyance and title issues do not exist.

         In the judgment of the Company, the purchase of the Partnership's
Property Interests together with interests in many of the same properties owned
by other Partnerships at approximately the same time will result in
efficiencies to the Company in aggregating such interests.  Swift's long-term
knowledge of the risks involved in these properties means that it is in a
better position to evaluate these risks than third parties.

         Based upon the Company's experience in purchasing properties, the lack
of additional costs often incurred in purchasing oil and gas properties in
which the purchaser has owned no interest, and the Company's intimate
familiarity with these Property Interests and consequent ability to evaluate
acquisition risks, it was deemed appropriate to pay a premium representing the
benefit to the Company arising from these factors.

         The amount of the premium principally was based upon management's
experience in purchasing properties which contain both producing reserves and
drilling potential, without any statistical or analytical study prepared by the
Company in the course of determining the amount of this premium.  Since 1979,
the Company, on behalf of itself and others, has gained a wide range of
experience with the valuation of oil and gas properties and the prices for
their purchase and sale, having purchased $478 million of such properties in
129 separate transactions.  Other purchasers might have determined it
inappropriate to pay  a premium, or if so, to pay a premium based upon other
factors or in a different amount.  Because there





                                       11
<PAGE>   379
has been no independent third party involved in the decision to pay this
premium or in the determination of its amount, and no fairness opinion has been
requested regarding this premium, conflicts of interest exist in its
determination, although the Managing General Partner believes, based upon its
knowledge of the oil and gas industry, its knowledge of the properties
involved, its experience in purchasing and selling oil and gas properties, and
the benefits from purchasing the Property Interests which are particular to the
Company, that the amount being offered to the Partnership to purchase its
Property Interests is fair.

"SPECIAL FACTORS" SECTION IN THE JOINT PROXY STATEMENT/PROSPECTUS

         The Special Factors section in the Joint Proxy Statement/Prospectus
contains a full discussion of the determination of the purchase price proposed
to be paid by the Managing General Partner to purchase the Partnership's
Property Interests.  In addition to those topics discussed at length in this
Supplement, the Joint Proxy Statement/Prospectus addresses alternative
transactions that were considered but not proposed for the Partnership and the
other 62 partnerships to whom similar proposals are being made simultaneously.
It also contains information regarding the prior relationships between the
Appraisers, the Partnerships and the Managing General Partner, the absence of a
request that an independent representative negotiate the terms of the purchase
of the Partnership's Property Interests by the Managing General Partner, the
manner in which expenses are to be borne for the transaction, the Managing
General Partner's source of funds to purchase the Partnership's Property
Interests, and the benefits that the Managing General Partner would receive
from purchasing such Property Interests.

ESTIMATES OF LIQUIDATING NET CASH DISTRIBUTION AMOUNT IF THE PROPOSAL IS
APPROVED

         The purchase price proposed to be paid to the Partnership for its oil
and gas assets is the Fair Market Value plus the purchase premium.  As is the
case with all oil and gas properties purchases, the purchase is proposed to be
made as of the date which the properties were evaluated (in this case December
31, 1997). A portion of the reserves used to establish the Fair Market Value
has been produced during 1998.  Most of the net revenue received by the
Partnership from the sale of such production since the proposed purchase date
(December 31, 1997) has been distributed to the partners during 1998 through
quarterly cash distributions or, to the extent not already distributed, will be
distributed as part of the Partnership's liquidating distributions.
Accordingly, the actual purchase price which will be paid to the Partnership
will be reduced by the amount of net production revenue received by the
Partnership after December 31, 1997.

         Set forth in the table below are estimated net proceeds that the
Partnership may realize from the sale of the Partnership's Property Interests,

(8)      Under the terms of the offer of Swift Common Stock to Eligible
         Purchasers, if the Investors in the Partnership approve the Proposal,
         such Investors will be Eligible Purchasers.  The minimum number of
         shares which can be purchased by an Eligible Purchaser is a round lot
         of 100 shares.  Based upon estimated net cash distribution of $108.52
         per $1,000 Unit, the number of Units shown above is the minimum number
         of Units which it will be necessary for an Investor to own in order to
         purchase a minimum 100 share round lot of Swift Common Stock without
         providing any additional funds from other sources.  This calculation
         is based upon an assumed purchase price of Swift Common Stock of
         $18.00 per share (which is the same price upon which the proforma
         financial statements contained in the Joint Proxy Statement/Prospectus
         are based) for an aggregate purchase price for 100 shares of Swift
         Common Stock of $1,800.  The minimum number of Units shown is subject
         to change, based upon the price for Swift Common Stock at a future
         date as specified under "Offering of Shares of Swift Energy Company
         Common Stock if Investors Approve the Proposal--Offer of Swift Common
         Stock--Purchase Price" in this Supplement.  However, if an Eligible
         Purchaser has interests in more than one Partnership, the cash
         distributions he will be entitled to receive may be aggregated to meet
         the minimum share purchase requirement of a round lot of 100 shares.

ESTIMATES OF NET CASH DISTRIBUTIONS AVAILABLE FROM CONTINUED OPERATIONS

         If the Partnership were to retain its Property Interests until they
have reached their economic limit, the table below estimates the return to
Investors, without regard to amounts distributable to the General Partners,
discounted to present value, based upon 1997 year-end pricing without
escalation and upon the discount assumptions used above.  The estimates of the
present value of future net cash distributions have been further reduced by
estimates of 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.
The following estimated future net revenues do not take into account any
additional costs which might be incurred by the Partnership due to needed
future maintenance or remedial work on the properties in which the Partnership
has an interest, which would reduce such net revenues.

(1)      Investors' future net revenues are based on the reserve estimates at
         December 31, 1997 using year-end 1997 prices without escalation.  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 "Special Factors--Reasons for the Proposal" in this
         Supplement.  The actual prices that will be received and the
         associated costs are likely to vary and may be more or less than those
         projected.  See "Partnership Business and Financial Condition" in this
         Supplement.

(2)      Estimated net cash distributions paid to Investors from January 1,
         1998 to September 30, 1998 in order to present this information on a
         comparative basis (in relation to the preceding table) as of September
         30, 1998.

(3)      Includes Investors' share of general and administrative expenses, and
         audit, tax, and reserve engineering fees.

(4)      Includes Investors' share of cash and net receivables of the
         Partnership as of December 31, 1997.

(5)      Based upon the Partnership's reserves until they have reached their
         economic limit.

(6)      Discounted at 10% per annum.

         The proceeds of all sales, to the extent available for net cash
distribution, are to be distributed to the partners in accordance with the
Partnership's limited partnership agreement.  The amounts finally distributed
will depend on results of operations until liquidation of the Partnership,
final costs and other contingencies and circumstances.

FAIRNESS OF PROPOSED SALE OF ASSETS TO THE MANAGING GENERAL PARTNER
   AS COMPARED TO CONTINUING OPERATIONS

         Based on the above tables, it is estimated that an Investor could
expect to receive $108.52 per $1,000 Unit upon the sale of the Partnership's
Property Interests as of September 30, 1998.  In comparison, it is estimated
that an Investor could expect to receive $131.95 per $1,000 Unit, discounted to
present value at 10% per annum ($297.18 per $1,000 Unit on an undiscounted
basis) if the Partnership continued operations.  The Managing General Partner
believes that the Proposal to sell the Partnership's Property Interest as
compared to continuing operations is fair to Investors for the reasons
discussed below.

         Although the estimates contained in the two tables above show that
estimated net cash distributions to Investors (based on net present value) from
continued operations would be approximately 22% higher than estimated net cash
distributions from selling the Partnership's Property Interests and liquidating
the Partnership currently, the Managing General Partner believes there is a
substantial advantage in receiving the liquidating net cash distribution in one
lump sum at this time. The estimates of net cash distributions from continued
operations are based upon 1997 year- end pricing.  It is highly likely that
over such a long period of time, oil and gas prices will vary often and
possibly widely, as has been demonstrated historically, from the prices used to
prepare these estimates.  Continued operations over such a long period of time
subject Investors to the risk of receiving lower levels of net cash
distributions if oil and gas prices over this period are lower on average than
those used in preparing the estimates of net cash distributions from continued
operations.  Continued operations also subject Investors' potential net cash
distributions 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.  The Managing General Partner also believes that there
is an advantage to Investors taking any funds to be received upon liquidation
and redeploying





                                       15
<PAGE>   383
those assets in other investments, rather than continuing to receive decreasing
levels of net cash distributions over such a long period of time.

         Because there is no active trading market for Units in the
Partnership, the only other comparable value for Units is the 1997 "Unit
Value," which, as explained below, is the amount calculated on an annual basis
under the terms of the limited partnership agreement at which the Managing
General Partner can offer to repurchase Units from Investors.  As of January 1,
1997, this "Unit Value" was $157.73 per $1,000 Unit.  In 1997, the Investors
received net cash distributions of $18.26 per $1,000 Unit, and are estimated to
receive another $10.50 per $1,000 Unit before September 30, 1998, which
converts to a comparable value of $128.97 per $1,000 Unit before any
adjustments to quantities of reserves or oil and gas prices during this almost
two year period.  Under the terms set out in the limited partnership agreement,
each year the Managing General Partner is required to furnish to Investors the
Unit Value, and Investors have the right to present their Units for purchase by
the Managing General Partner for the Unit Value.  The Unit Value amount is
determined on an entirely different basis than the estimates of fair market
value by the Appraisers.  Furthermore, the Unit Value was calculated over one
year ago, with a valuation date of January 1, 1997, as opposed to the date for
assessment of Fair Market Value being December 31, 1997. Because of significant
changes in oil and gas prices within a year's time, in addition to the changes
in reserve quantities during that period, the calculation of Unit Value as of
January 1, 1997, and the Fair Market Value as of December 31, 1997, are not
comparable.  Unit Value is derived by taking 70% of the present value of proved
oil and gas reserves (discounted at 10% per annum) calculated on an escalated
pricing basis, plus cash and accounts receivable less outstanding debts and
obligations of the Partnership.

         Although the PV-10 Value of the Partnership's Property Interests is
higher than the purchase price proposed if the Proposal is approved, the
Managing General Partner does not believe that the PV-10 Value accurately
reflects the amount that oil and gas industry members are currently paying to
purchase producing properties on the open market.

FAIRNESS OF PROPOSED SALE

         The Managing General Partner believes that the entire transaction
related to the Proposal involving the proposed method of sale of the
Partnership's Property Interests is fair to Investors for the following
reasons, without giving any particular weight to any reason:

         1.      The Managing General Partner believes that the most important
                 element of the Proposal is the determination of the Fair
                 Market Value of the Partnership's Property Interests.  The
                 price to be paid by the Company to purchase the Partnership's
                 Property Interests was determined in the Managing General
                 Partner's sole judgment by adding a 7.5% premium to the higher
                 of the two estimates by the Appraisers of the fair market
                 value of the Partnership's Property Interests.  Two of the
                 three Appraisers are qualified independent petroleum
                 engineering firms and the other is an investment banking firm.
                 The factors and methods used by the Appraisers in determining
                 Fair Market Value are discussed in detail under "Special
                 Factors--Independent Appraisal of the Fair Market Value of
                 Property Interests of the Partnerships," "--Fair Market
                 Value," "--Valuation by Petroleum Engineering Consultants,"
                 "--Valuation by CIBC Oppenheimer" and "--Collective Analysis
                 of Purchase Price" in the Joint Proxy Statement/Prospectus.





                                       16
<PAGE>   384
         2.      No transaction will take place unless the Proposal is approved
                 by Investors holding at least a majority of the interests in
                 such Partnership (without any vote by the Managing General
                 Partner).

         3.      The Special Transactions Committee made the determination as
                 to the retention of the Appraisers and approved the fair
                 market value estimates provided by the Appraisers and
                 recommended the reports of the Appraisers to the Board of
                 Directors of the Company.  The Special Transactions Committee
                 is comprised solely of independent directors of the Company.

         4.      If the Proposals are approved by investors in any of the 63
                 Partnerships considering similar proposals, it is likely that
                 the Managing General Partner will expend the capital necessary
                 to develop non- producing reserves on the Property Interests
                 purchased by the Managing General Partner from those
                 Partnerships.  If all of the Property Interests which are the
                 subject of the Proposals are acquired by the Company, such
                 Property Interests in the aggregate will constitute less than
                 20% of the Company's total assets.  Because the Managing
                 General Partner would be the beneficiary of any such increase
                 in value, the Managing General Partner is hereby offering to
                 Eligible Purchasers the opportunity to purchase up to
                 2,500,000 shares of Common Stock of the Company.  There is no
                 requirement that any purchase of Swift's Common Stock be made.
                 See "Offer of Swift Common Stock" below.

         5.      In structuring the Proposal and related transactions, the
                 Managing General Partner considered that any sale of
                 Partnership Property Interests, whether to the Managing
                 General Partner or to a third party, would be a taxable
                 transaction.  Thus, if an Investor subject to federal income
                 tax chooses to use the proceeds received on liquidation of
                 that Investor's Partnership to purchase Swift Common Stock,
                 tax will still have to be paid on any taxable income resulting
                 from the Partnership's sale of oil and gas assets, without
                 regard to whether the Investor has cash proceeds remaining
                 from his liquidating distribution to pay such tax.

         The determination by the Special Transactions Committee to pay the
purchase premium, the independent Appraisers' determination of the fair market
value of the properties and the payment of a 7.5% premium do not necessarily
remove the substantial conflicts of interest which exist in the transaction
between the Managing General Partner's serving in that capacity on behalf of
the Partnership and also acting as the purchaser of the Property Interests from
the Partnership.  No fairness opinion was requested or received regarding the
ultimate purchase price to be paid by the Managing General Partner to purchase
the Partnership's oil and gas assets.  The Managing General Partner determined
that rather than setting the purchase price for Partnership Property Interests
itself, it would be preferable to instead request three different independent
Appraisers to determine two sets of fair market values at which such Property
Interests should be purchased, and then to choose the higher of those two
values.  The Managing General Partner believes that when the Appraisers
rendered their opinions as to the "fair market value" of the Partnership's
Property Interests, inherent within their appraisal opinions were the
Appraisers' determination that these "fair market values" were "fair," or such
determinations would not have been made.  Consequently, no independent fairness
opinion was requested regarding "fair market values" or upon the premium.  The
Managing General Partner believes that adding a 7.5% premium to the highest of
the two fair market value determinations made by the three Appraisers only
serves to increase the amount to be





                                       17
<PAGE>   385
paid to Investors upon liquidation of the Partnership and does not require a
separate fairness opinion.  The determination by a third party purchaser as to
the purchase price might be more or less than that being proposed by the
Managing General Partner as a purchase price for these Property Interests.

         The determination to submit the Proposal to Investors in which the
Company would purchase the Property Interests of the Partnership was deemed by
the Managing General Partner to be the most appropriate time and method for
liquidation of the Partnership.  This decision was made in light of full
consideration by the Managing General Partner of its fiduciary obligations to
Investors.  Furthermore, the decision to use three Appraisers, rather than one,
and to have the Appraisers actually set the fair market value for purchase of
the Property Interests, rather than the Managing General Partner setting that
value and requesting a fairness opinion, were based upon the Managing General
Partner's consideration of the substantial conflicts of interest which exist in
the transactions covered hereby.

See "Special Factors--Fairness of Proposed Sale" in the Joint Proxy
Statement/Prospectus.

MANAGING GENERAL PARTNER BENEFITS

         Benefits accruing to the Company resulting from the purchase of the
Partnerships' Property Interests include the following:  the Managing General
Partner will share the benefits available to Investors through liquidating its
Partnership interests (including both its general partner interests and any
Units it owns) and receiving the same value of those interests as Investors.
Additionally, the Company intends to profit from purchasing the Partnership's
Property Interests through a return on capital used to purchase those oil and
gas assets and invest in their development.  By purchasing the Partnership's
Property Interests itself, the Managing General Partner will be able to
maintain its position as operator of certain properties in which the
Partnership owns an interest.  Consequently, the Managing General Partner would
continue to receive operating fees as operator of those properties.  The sale
of the Partnership's Property Interests to the Managing General Partner will
have no effect or an inconsequential effect on the Managing General Partner's
net book value and net earnings.  However, the purchase of all of the oil and
gas assets of the Partnerships would increase the Company's proved reserves,
cash flow and total assets by a significant amount.  Lastly, if individual
Investors which approve the Proposal elect to purchase Company Common Stock,
rather than receiving cash upon liquidation of the Partnership, the Company
will benefit by using stock to pay the purchase price, rather than using its
available cash resources or borrowing facilities.

Statement/Prospectus.

         The Partnership does not have a Companion Partnership, therefore no
approval of a simultaneous proposal by any other partnership is required in
order for the sale of the Partnership's Property Interests to take place
following approval of the Proposal by its Investors.

                             VOTING ON THE PROPOSAL

         The Joint Proxy Statement/Prospectus and the Form of Proxy enclosed
with this Supplement are being provided for use at the Special Meeting of
Investors of the Partnership and at any adjournment or postponement of such
meeting (the "Meeting") to be held at 16825 Northchase Drive, Houston, Texas at
4:00 p.m. Central Time on ______, ___________, 1998.  The Meeting is being
called for the purpose of





                                       18
<PAGE>   386
considering and voting upon the Proposal to sell all of the oil and gas assets
of the Partnership to the Company, and to dissolve, wind up and terminate the
Partnership and to transact such other business as may be properly presented at
the Meeting, all in accordance with the terms and provisions of the
Partnership's limited partnership agreement (the "Partnership Agreement"), and
the Texas Revised Limited Partnership Act (the "Texas Act").  This Joint Proxy
Statement/Prospectus and enclosed Form of Proxy are first being mailed to
Investors on or about _____________, 1998.

          Pursuant to the terms of the Partnership Agreement, the Partnership,
if not terminated earlier, will continue in being through January 1, 2016, at
which point it will terminate automatically.

         Under the Partnership Agreement, the Proposal must be approved by the
affirmative vote of Investors holding 51% or more of the Units in the
Partnership as of the Record Date (defined below).  Therefore, an abstention by
an Investor will have the same effect as a vote against the Proposal.  The
solicitations are being made for votes in favor of the Proposal (which will
result in liquidation and dissolution of the Partnership).  As of the Record
Date, 10,447 Units were outstanding and held by record holders (excluding the
Units held by the Managing General Partner as discussed below).  Accordingly,
the affirmative vote of holders of at least 5,328 Units is required to approve
the Proposal.  Each Investor appearing on the records of the Partnership as of
______, 1998 (the "Record Date") is entitled to notice of the Meeting and is
entitled to one vote for each Unit held by such Investor. VJM Corporation, a
California corporation, is the Special General Partner of the Partnership, and
owns a 1.0% interest in the Partnership as a general partner, but owns no
Units.  The Managing General Partner owns a general partner interest in the
Partnership of 9.0%.  Additionally, the Managing General Partner owns 3,674
outstanding Units in the Partnership, which ownership results from the Managing
General Partner's purchase over the life of the Partnership of Units from
Investors under the right of presentment, contained in the Partnership
Agreement.  Under the Partnership Agreement, the Managing General Partner may
not vote any Units owned by it for matters such as the Proposal.  The Managing
General Partner's non-vote, in contrast to abstention by Investors, will not
affect the outcome, because for purposes of adopting the Proposal, its Units
are excluded from the total number of voting Units.

VOTE REQUIRED

         The actual proxy to be used to register the vote on the Proposal
before you is the separate green sheet of paper included with this Supplement
and Joint Proxy Statement/Prospectus.  PLEASE USE THE GREEN PROXY TO CAST YOUR
VOTE ON THE PROPOSAL.

         If a proxy is properly signed and is not revoked by an Investor, the
Units it represents will be voted in accordance with the instructions of the
Investor.  If no specific instructions are given, the Units will be voted FOR
the Proposal.  An Investor may revoke his proxy at any time before it is voted
at the Meeting.  Any Investor who attends the Meeting and wishes to vote in
person may revoke his proxy at that time.  Otherwise, an Investor 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.

SOLICITATION

         The solicitation is being made by the Partnership.  The Partnership
will bear the costs of the preparation of the Joint Proxy Statement/Prospectus
and of the solicitation of proxies and such costs will be allocated 90% to the
Investors and 10% to the general partners pursuant to the terms of the
Partnership Agreement.  As the Managing General Partner holds approximately
26.01% of the Units held by all Investors, 26.01% of the costs borne by the
Investors will be borne by the Managing General Partner, in addition to the
portion of the Partnership's total costs borne by the general partners by
virtue of their interest in the Partnership as general partners.  Solicitations
will be made primarily by mail.  In addition, a number of regular or temporary
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 Investors to encourage the return of proxies, although it does not
anticipate doing so.

                  PARTNERSHIP BUSINESS AND FINANCIAL CONDITION

         The Partnership is a Texas limited partnership formed January 9, 1987.
Units in the Partnership are registered under Section 12(g) of the Securities
Exchange Act of 1934.  The Partnership owns Property Interests in producing oil
and gas properties within the continental United States.  By the end of
December 1987, the Partnership had expended all of its original capital
contributions for the purchase of Property Interests in oil and gas producing
properties.  During 1997, approximately 75% of the Partnership's revenue was
attributable to natural gas production.  From time to time, the Partnership has
performed workovers and recompletions on wells in which the Partnership has
Property Interests, using funds advanced by the Managing General Partner or
third parties, to perform these operations, which amounts have been
subsequently repaid.  For information about the business of the Partnership,
see the attached Annual Report on Form 10-K for the year ended December 31,
1997 and Quarterly Report on Form 10-Q for the quarter ended June 30, 1998.

         Investors made contributions of $14,121,095 in the aggregate to the
Partnership, the net proceeds of which have all been invested.  The Managing
General Partner has made capital contributions with respect to its general
partner interest of $112,295.  Additionally, pursuant to the right of
presentment set forth in the Partnership Agreement, it has purchased 3,674
Units from Investors.  From inception through July 31, 1998, the Partnership
has made net cash distributions to its Investors totaling $7,964,607.  Details
of the amounts of cash distributions made to partners over the past three years
and nine months are set out under "Cash Distributions" below.  Through July 31,
1998, the Managing General Partner has received net cash distributions from the
Partnership of $848,331 with respect to its general partner interest, and
$199,956 related to its limited partner interest.  On a per Unit basis,
Investors had received, as of July 31, 1998, $564.02 per $1,000 Unit, or
approximately 56.4% 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.  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 $18.59 per
barrel of oil and $1.53 per Mcf of natural gas.  The





                                       20
<PAGE>   388
majority of the Partnership's Property Interests were acquired by the end of
December 1987 and were comprised principally of natural gas reserves.  At that
time current prices were predicted to escalate according to certain parameters
from then current levels to approximately $32.22 per barrel of oil and $3.82
per Mcf of natural gas during 1997.  The predicted price increases did not
occur, and prices fell precipitously from 1990 to 1991.  Most of the
Partnership's reserves were produced from 1987 to 1991, during which time the
oil prices received by the Partnership for its production in fact averaged
$18.22 per barrel, but the prices for the Partnership's principal asset,
natural gas, averaged approximately $1.55 per Mcf.  A comparison of gas prices
as described in this paragraph appears in the graph presented below.

The following graphs illustrate the effect on Partnership performance of the
variance between gas prices projected at the time of acquisition of the
Partnership's Property Interests and actual gas prices received for production
(as illustrated in the second graph) during the Partnership's existence.
Information is presented as to gas prices only due to the fact that a
substantial majority of the Partnership's production has been natural gas.

                                       22
<PAGE>   390
         Lower prices also have 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.

CASH DISTRIBUTIONS

         Cash distributions are made to the partners in the Partnership on a
quarterly basis.  During the past three years and the first nine months of
1998, aggregate cash distributions made to all partners in the Partnership
(including the Managing General Partner) and the cash distributions per Unit
made to the Investors were:

TRANSACTIONS BETWEEN THE MANAGING GENERAL PARTNER AND THE PARTNERSHIP

         Under the Partnership Agreement, the Managing General Partner has
received certain compensation for its services and reimbursement for
expenditures made on behalf of the Partnership, which was paid at closing of
the offering of interests in the Partnership, in addition to revenues
distributable to the Managing General Partner with respect to its general
partner interest or with respect to Units it has purchased under the Investors'
right of presentment.  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
                 $353,027, internal acquisition costs reimbursements of
                 $297,124 and formation costs reimbursements of $282,422 from
                 the Partnership from inception through December 31, 1997, none
                 of which has been received during the two years ended December
                 31, 1997.

         o       The Managing General Partner receives operating fees for wells
                 in which the Partnership has Property Interests and for which
                 the Managing General Partner or its affiliates serve as
                 operator.  During the years ended December 31, 1997 and
                 December 31, 1996 the aggregate operating fees paid to the
                 Company as operator by the Partnership were $29,245 and
                 $38,456, respectively.  Monthly operating fees range from $500
                 to $900 per well on an 8/8th's basis (i.e., the total amount
                 of operating fees paid by all interest owners in the well).
                 If the Property Interests are sold to the Managing General
                 Partner, there should be





                                       23
<PAGE>   391
                 no change in its status as operator for a number of the wells
                 in which the Partnership has a Property Interest.  The
                 Managing General Partner believes that it will be positively
                 affected, on the other hand, by liquidation of the
                 Partnership, both on the basis of its ownership interest in
                 the Partnership and for other reasons set out under "Special
                 Factors--Managing General Partner Benefits" in this
                 Supplement.

         o       The Managing General Partner is entitled to be reimbursed 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
                 Investors' original capital contributions to the Partnership
                 relative to investor contributions to all public partnerships
                 formed to purchase interests in producing properties for which
                 the Managing General Partner serves in that capacity.  Through
                 December 31, 1997, the Managing General Partner had received
                 $1,008,876 in the general and administrative overhead
                 allowance from the Partnership, of which $43,568 and $107,566
                 have been reimbursed during the years ended December 31, 1997
                 and December 31, 1996, respectively.

         o       The Managing General Partner has been reimbursed $72,761 in
                 direct expenses by the Partnership, all of which was billed
                 by, and then paid directly to, third party vendors, of which
                 $5,161 and $7,134 have been reimbursed during the years ended
                 December 31, 1997 and December 31, 1996, respectively.

NO TRADING MARKET

         There is no trading market for the Units, and none is expected to
develop, as described above under "Special Factors--Fairness of Proposed Sale
of Assets to the Managing General Partner as Compared to Continuing
Operations." Under the Partnership Agreement, Investors 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 the Partnership
Agreement.  Originally 1,580 Investors invested in the Partnership.  As of
__________, 1998, there were 1,201 Investors (excluding the Managing General
Partner).  The number of Units in the Partnership issued and outstanding at
that date was 14,121.10.  Through December 31, 1997, the Managing General
Partner had purchased 3,674 Units from Investors pursuant to the right of
presentment.  The Managing General Partner does not have an obligation to
repurchase Investor interests pursuant to this right of presentment, but merely
an option to do so when such interests are presented for repurchase.

PRINCIPAL HOLDERS OF INVESTOR UNITS

         The Managing General Partner holds 26.01% of all outstanding Units of
the Partnership, resulting from the purchase of Units from Investors under
their right of presentment.  To the knowledge of the Managing General Partner,
there is no other 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.

                   SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES

GENERAL

         The following briefly summarizes the federal income tax consequences
set forth under "Federal Income Tax Consequences of Adoption of the Proposals"
in the Joint Proxy Statement/Prospectus.  Statements of legal conclusions
herein regarding tax consequences are based upon an opinion of Hoops & Levy,
L.L.P., Special Tax Counsel, 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 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 Investors.

         A MORE COMPLETE SUMMARY OF THE FEDERAL INCOME TAX CONSEQUENCES TO
INVESTORS MAY BE FOUND IN THE REGISTRATION STATEMENT IN "FEDERAL INCOME TAX
CONSEQUENCES OF ADOPTION OF THE PROPOSALS."  THIS SUMMARY DOES NOT DESCRIBE ALL
THE TAX ASPECTS WHICH MAY AFFECT INVESTORS NOR IS IT A COMPLETE DESCRIPTION OF
THE TAX ASPECTS IT DOES DESCRIBE.  It is generally directed to individual
Investors who are the original purchasers of the Units and hold interests in
the Partnership as "capital assets" (generally, property held for investment).
Each Investor that is a corporation, trust, estate, tax exempt entity, or other
partnership 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.

         TAXABLE GAIN OR LOSS UPON SALE OF PROPERTIES

         Investors will realize and recognize gain or loss, or a combination of
both, upon the Partnership's sale of its properties prior to liquidation.  It
is projected, however, that Investors will realize a net taxable gain upon the
sale of the Partnership properties.  Because the oil and gas properties, and
related assets, owned by the Partnership are properties used in a trade or
business, the character of gains and losses realized by the Investors generally
will be governed by Section 1231 of the Code.  Realized gains and losses
generally must be recognized and reported in the year the sale occurs. Each
Investor's recognized allocable share of the net Partnership 1231 gains or
losses must be netted with that Investor's individual section 1231 gains and
losses recognized during the year in order to determine the character of such
net gains or net losses under section 1231.  Net gains will be treated as
capital gains except to the extent recharacterized as ordinary income due to
recapture and net losses will be treated as ordinary losses.





                                       25
<PAGE>   393
         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 an Investor in liquidation is less than such Investor's adjusted
tax basis in his Partnership interest, the Investor will realize and recognize
a capital loss to the extent of the excess.  If the amount of cash distributed
is greater than such Investor's adjusted tax basis in his Partnership interest,
the Investor will recognize a capital gain to the extent of the excess.
Because each Investor 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 Investors will be less than
such Investors' bases in their Partnership interests and thus will generate
capital losses.

         CAPITAL GAIN TAX

         Net long-term capital gains of individuals, trusts and estates
generally will be taxed at a maximum rate of 20%, while ordinary income,
including income from the recapture of intangible drilling and development
costs, depreciation and depletion, will be taxed at a maximum rate depending on
that Investor's taxable income of 36% or 39.6%.


         PASSIVE LOSS LIMITATIONS

         Investors 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.

         An Investor'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.

         THE FOREGOING DISCUSSION IS A SUMMARY OF THE INCOME TAX CONSEQUENCES
SET FORTH UNDER "FEDERAL INCOME TAX CONSEQUENCES OF ADOPTION OF THE PROPOSALS"
IN THE JOINT PROXY STATEMENT/PROSPECTUS. IT IS NOT INTENDED AS AN ALTERNATIVE
FOR INDIVIDUAL TAX PLANNING.  EACH INVESTOR SHOULD CONSULT HIS, HER OR ITS OWN
TAX ADVISOR CONCERNING THE PARTICULAR FEDERAL, STATE, LOCAL, FOREIGN AND OTHER
TAX CONSEQUENCES APPLICABLE TO HIM, HER OR IT OF THE SALE OF PROPERTIES AND THE
LIQUIDATION OF THE PARTNERSHIP.

VOTING PROCEDURES

         The Joint Proxy Statement/Prospectus contains detailed procedures to
be followed by investors in voting as to the Partnerships' Proposals.  Strict
compliance with these procedures must be followed in order for the elections of
the investors marked on the subscription agreement to be effective.  The
following is a summary of certain of these procedures:

         (a)  Investors may make their elections on the subscription agreement
signed by all subscribers commencing upon delivery of this Joint Proxy
Statement/Prospectus and continuing until the Due Date (as defined below).

         (b)  If Investors in the Partnership vote to approve the Proposal,
Investors may revoke their election to purchase Shares offered hereby at any
time until the Due Date by delivering or faxing a letter so stating or a later
dated subscription agreement, both of which must be signed by such revoking
subscribers, to the Company at 16825 Northchase Drive, Suite 400, Houston,
Texas 77060, fax number (281) 874-2818; Attention:  Investor Relations
Department.

         (c)  Investors failing to submit proxies by the Due Date will be
deemed to have voted against their Partnership's Proposal and, if their
Partnership approves its Proposal, will receive, along with non-subscribing
investors who timely submitted proxies,  their distribution in cash.  See "The
Proposals--Vote Required" in the Joint Proxy Statement/Prospectus.

OFFER OF SWIFT COMMON STOCK

         Investor Election to Purchase Shares

         In connection with the concurrent Proposals for sale of all of the oil
and gas assets of 63 Partnerships to the Company and the subsequent termination
of such Partnerships, the Company is offering up to 2,500,000 shares of the
Company's Common Stock.  Upon approval of the Proposals by the Partnership and
sale of the Partnership's oil and gas assets, the Partnership's assets will
consist solely of cash which each investor as an Eligible Purchaser of such
Partnerships will be entitled to receive as a distribution.  The Company hereby
offers to each such Eligible Purchaser the opportunity to purchase shares of
Common Stock with all or any portion of the cash distribution such Eligible
Purchaser will be entitled to receive, provided that a minimum round lot of 100
shares must be purchased.  If an Eligible Purchaser has interests in more than
one Partnership, the cash distributions he will be entitled to receive may be
aggregated to meet the minimum round lot of 100 shares requirement.  Each such
Eligible Purchaser may purchase shares of Common Stock with funds in addition
to their cash distributions in order to purchase (i) the minimum round lot of
100 shares, or (ii) shares in addition to the number of shares for which their
cash distribution will be applied, subject to prorata limitations in the event
of oversubscription.  No fractional shares will be sold.

Attn: Special Transactions Committee    FAIR MARKET VALUE ESTIMATE
        Board of Directors              SWIFT ENERGY INCOME PARTNERS 1986-D LTD.
                                        97-003-133


Gentlemen:

At your request, we have audited the proved, probable and possible reserves and
future net cash flow as of December 31, 1997, prepared by Swift Energy Company
("Swift") for certain interests owned by the partners in Swift Energy Income
Partners 1986-D Ltd. This audit has been conducted according to the Standards
Pertaining to the Estimating and Auditing of Oil and Gas Reserve Information
approved by the Board of Directors of the Society of Petroleum Engineers on
October 30, 1979.  We have reviewed these properties and where we disagreed
with the Swift reserve estimates, Swift revised its estimates to be in
agreement.

From this audit, and in consultation with J.R. Butler and Company, our estimate
of the fair market value of this partnership is $1,567,013.

Fair market value as used herein is defined as that price that a willing buyer
will pay and a willing seller will accept at a given point in time, with
neither the buyer nor the seller under any compulsion to buy or sell, and both
having reasonable knowledge of all the material circumstances.

To estimate the fair market value attributable to the proved developed
producing reserves, the 10 percent discounted future net cash flow was
multiplied by a suitable factor (less than one) to account for the risk
associated with the reserves, operating expenses, and prices and to approximate
tax consequences. The internal rate of return and payout time were computed for
this quantity and compared with those at which current acquisitions are
completed. Suitable adjustments are then made to correspond to these two
financial indices. Proved developed nonproducing, proved undeveloped, probable
and possible reserves require capital investments and must be treated
appropriately. For these cases, the capital is added to the discounted net cash
flow, then multiplied by a suitable risk factor and the capital then
subtracted. This has the effect that capital is spent with certainty and the
operating cash income is burdened with the risk. Internal rate of return and
payout time are calculated for each estimate to establish reasonableness based
upon the reserve category. The estimated future net cash flow is that cash flow
which will be realized from the sale of the estimated net reserves after
deduction of royalties, ad valorem and production taxes, direct operating

costs and capital expenditures, when applicable.  Surface and well equipment
salvage values and well plugging and field abandonment costs have not been
considered in the cash flow projections.  Future net cash flow as stated in
this report is before the deduction of federal income tax.

The following parameters are incorporated in the economic projections
referenced in this report.  Initial oil prices are the existing prices on
December 31, 1997, and are escalated 3.5 percent per year beginning in 1999
through the year 2013 after adjusting for transportation and gravity variances.
Initial natural gas prices are those existing on December 31, 1997, and are
escalated 3.5 percent per year beginning in 1999 through the year 2013 after
adjusting for transportation and Btu content.  Operating expenses are escalated
at an annual rate of 3.5 percent until the year 2013.  The actual prices that
will be received and the associated costs may be more or less than those
projected.

For those wells with sufficient production history, reserve estimates and rate
projections are based on the extrapolation of established performance trends.
Reserves for other producing and nonproducing properties have been estimated
from volumetric calculations and analogy with the performance of comparable
wells.  The reserves referenced in this study are estimates only and should not
be construed as exact quantities.  Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available. The proved reserves are
estimated in accordance with the definitions included in the Securities and
Exchange Commission Regulation S-X, Rule 4-10(a) except for the price and cost
escalations. The definitions are included in part as Attachment I. The probable
and possible reserves conform to the definitions approved by the Society of
Petroleum Engineers, Inc. The definitions are included as Attachment II.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented.  The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December. Interim production to December 31, 1997, has been
estimated.  Operating expenses as supplied by Swift were not audited, but were
reviewed for reasonableness. No independent well tests, property inspections or
audits of operating expenses were conducted by our staff in conjunction with
this study.  We did not verify or determine the extent, character, obligations,
status or liabilities, if any, arising from any current or possible future
environmental liabilities that might be applicable.

In order to audit the reserves, costs and future cash flows referenced in this
report, we have relied in part on geological, engineering and economic data
furnished by our client.  Although we have made a best efforts attempt to
acquire all pertinent data and to analyze it carefully with methods accepted by
the petroleum industry, there is no guarantee that the volumes of oil or gas or
the cash flows projected will be realized.  The reserve and cash flow
projections referenced in this report may require revision as additional data
become available.

         4.    No instructions were given and no limitations were imposed by
               Swift on the scope or methodology to be used by us in preparing
               such estimates; we did not accept or incorporate any assumptions
               from Swift, but merely called upon Swift to the extent customary
               in the oil and gas industry to  gather and provide certain
               background information which we determined to be relevant and
               appropriate; we determined what information to use; and how and
               to what extent such information should be relied upon in
               estimating the fair market values shown above.  

If investments or business decisions are to be made in reliance on these
estimates by anyone other than our client, such person with the approval of our
client is invited to visit our offices at his expense so that he can evaluate
the assumptions made and the completeness and extent of the data available on
which our estimates are based.

Any distribution or publication of this report or any part thereof must include
this letter in its entirety.

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                         PETROLEUM RESERVES DEFINITIONS
   SOCIETY OF PETROLEUM ENGINEERS (SPE) AND WORLD PETROLEUM CONGRESS (WPC)(1)

Reserves are those quantities of petroleum which are anticipated to be
commercially recovered from known accumulations from a given date forward. All
reserve estimates involve some degree of uncertainty. The uncertainty depends
chiefly on the amount of reliable geologic and engineering data available at the
time of the estimate and the interpretation of these data. The relative degree
of uncertainty may be conveyed by placing reserves into one of two principal
classifications, either proved or unproved. Unproved reserves are less certain
to be recovered than proved reserves and may be further sub-classified as
probable and possible reserves to denote progressively increasing uncertainty in
their recoverability.

The intent of the SPE and WPC in approving additional classifications beyond
proved reserves is to facilitate consistency among professionals using such
terms. In presenting these definitions, neither organization is recommending
public disclosure of reserves classified as unproved. Public disclosure of the
quantities classified as unproved reserves is left to the discretion of the
countries or companies involved.

Estimation of reserves is done under conditions of uncertainty. The method of
estimation is called deterministic if a single best estimate of reserves is made
based on known geological, engineering and economic data. The method of
estimation is called probabilistic when the known geological, engineering, and
economic data are used to generate a range of estimates and their associated
probabilities. Identifying reserves as proved, probable, and possible has been
the most frequent classification method and gives an indication of the
probability of recovery. Because of potential differences in uncertainty,
caution should be exercised when aggregating reserves of different
classifications.

Reserves estimates will generally be revised as additional geologic or
engineering data become available or as economic conditions change. Reserves do
not include quantities of petroleum being held in inventory, and may be reduced
for usage of processing losses if required for financial reporting.

Reserves may be attributed to either natural energy or improved recovery
methods. Improved recovery methods include all methods for supplementing natural
energy or altering natural forces in the reservoir to increase ultimate
recovery. Examples of such methods are pressure maintenance, cycling,
waterflooding, thermal methods, chemical flooding, and the use of miscible and
immiscible displacement fluids. Other improved recovery methods may be developed
in the future as petroleum technology continues to evolve.

PROVED RESERVES

Proved reserves are those quantities of petroleum which, by analysis of
geological and engineering data, can be estimated with reasonable certainty to
be commercially recoverable, from a given date forward, from known reservoirs
and under current economic conditions, operating methods, and government
regulations. Proved reserves can be categorized as developed or undeveloped.

If deterministic methods are used, the term reasonable certainty is intended to
express a high degree of confidence that the quantities will be recovered. If
probabilistic methods are used, there should be at least a 90% probability that
the quantities actually recovered will equal or exceed the estimate.

Establishment of current economic conditions should include relevant historical
petroleum prices and associated costs and may involve an averaging period that
is consistent with the purpose of the reserve estimate, appropriate contract
obligations, corporate procedures, and government regulations involved in
reporting these reserves.

In general, reserves are considered proved if the commercial producibility of
the reservoir is supported by actual production or formation tests. In this
context, the term proved refers to the actual quantities of petroleum reserves
and not just the productivity of the well or reservoir. In certain cases,
proved reserves may be assigned on the basis of well logs and/or core analysis
that indicate the subject reservoir is hydrocarbon bearing and is analogous to
reservoirs in the same area that are producing or have demonstrated the ability
to produce on formation tests.

The area of the reservoir considered as proved includes (1) the area delineated
by drilling and defined by fluid contacts, if any, and (2) the undrilled
portions of the reservoir that can reasonably be judged as commercially
productive on the basis of available geological and engineering data. In the
absence of data on fluid contacts, the lowest known occurrence of hydrocarbons
controls the proved limit unless otherwise indicated by definitive geological,
engineering or performance data.

Reserves may be classified as proved if facilities to process and transport
those reserves to market are operational at the time of the estimate or there is
a reasonable expectation that such facilities will be installed. Reserves in
undeveloped locations may be classified as proved undeveloped provided (1) the
locations are direct offsets to wells that have indicated commercial production
in the objective formation, (2) it is reasonably certain such locations are
within the known proved productive limits of the objective formation, (3) the
locations conform to existing well spacing regulations where applicable, and (4)
it is reasonably certain the locations will be developed. Reserves from other
locations are categorized as proved undeveloped only where interpretations of
geological and engineering data from wells indicate with reasonable certainty
that the objective formation is laterally continuous and contains commercially
recoverable petroleum at locations beyond direct offsets.

Reserve which are to be produced through the application of established improved
recovery methods are included in the proved classification when (1) successful
testing by a pilot project or favorable response of an installed program in the
same or an analogous reservoir with similar rock and fluid properties provides
support for the analysis on which the project was based, and, (2) it is
reasonably certain that project will proceed. Reserves to be recovered by
improved recovery methods that have yet to be established through commercially
successful applications are included in the proved classification only (1) after
a favorable production response from the subject reservoir from either (a) a
representative pilot or (b) an installed program where the response provides
support for the analysis on which the project is based and (2) it is reasonably
certain the project will proceed.

UNPROVED RESERVES

Unproved reserves are based on geologic and/or engineering data similar to that
used in estimates of proved reserves; but technical, contractual, economic, or
regulatory uncertainties preclude such reserves being classified as proved.
Unproved reserves may be further classified as probable reserves and possible
reserves.

Unproved reserves may be estimated assuming future economic conditions different
from those prevailing at the time of the estimate. The effect of possible future
improvements in economic conditions and technological developments can be
expressed by allocating appropriate quantities of reserves to the probable and
possible classifications.

PROBABLE RESERVES

Probable reserves are those unproved reserves which analysis of geological and
engineering data suggests are more likely than not to be recoverable. In this
context, when probabilistic methods are used, there should be a least a 50%
probability that the quantities actually recovered will equal or exceed the sum
of estimated proved plus probable reserves.

In general, probable reserves may include (1) reserves anticipated to be proved
by normal step-out drilling where subsurface control is inadequate to classify
these reserves as proved, (2) reserves in formations that appear to be
productive based on well log characteristics but lack core data or definitive
tests and which are not analogous to producing or proved reservoirs in the area,
(3) incremental reserves attributable to infill drilling that could have been
classified as proved if closer statutory spacing had been approved at the time
of the estimate, (4) reserves attributable to improved recovery methods that
have been established by repeated commercially successful applications when (a)
a project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir characteristics appear favorable for commercial application, (5)
reserves in an area of the formation that appears to be separated from the
proved area by faulting and the geologic interpretation indicates the subject
area is structurally higher than the proved area, (6) reserves attributable to a
future workover, treatment, re-treatment, change of equipment, or other
mechanical procedures, where such procedure has not been proved successful in
wells which exhibit similar behavior in analogous reservoirs, and (7) 
incremental reserves in proved reservoirs where an alternative interpretation of
performance or volumetric data indicates more reserves than can be classified as
proved.

POSSIBLE RESERVES

Possible reserves are those unproved reserves which analysis of geological and
engineering data suggests are less likely to be recoverable than probable
reserves. In this context, when probabilistic methods are used, there should be
a least a 10% probability that the quantities actually recovered will equal or
exceed the sum of estimated proved plus probable plus possible reserves.

In general, possible reserves may include (1) reserves which, based on
geological interpretations, could possibly exist beyond areas classified as
probable, (2) reserves in formations that appear to be petroleum bearing based
on log and core analysis but may not be productive at commercial rates, (3)
incremental reserves attributed to infill drilling that are subject to technical
uncertainty, (4) reserves attributed to improved recovery methods when (a) a
project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir

<PAGE>   404

characteristics are such that a reasonable doubt exists that the project will be
commercial, and (5) reserves in an area of the formation that appears to be
separated from the proved area by faulting and geological interpretation
indicates the subject area is structurally lower than the proved area.

RESERVE STATUS CATEGORIES

Reserve status categories define the development and producing status of wells
and reservoirs.

     DEVELOPED: Developed reserves are expected to be recovered from existing
     wells including reserves behind pipe. Improved recovery reserves are
     considered developed only after the necessary equipment has been installed,
     or when the costs to do so are relatively minor. Developed reserves may be
     sub-categorized as producing or non-producing.

         PRODUCING: Reserves subcategorized as producing are expected to be
         recovered from completion intervals which are open and producing at the
         time of the estimate. Improved recovery reserves are considered
         producing only after the improved recovery project is in operation.

         NON-PRODUCING. Reserves subcategorized as non-producing include shut-in
         and behind-pipe reserves. Shut-in reserves are expected to be recovered
         from (1) completion intervals which are open at the time of the
         estimate but which have not started producing, (2) wells which were
         shut-in for market conditions or pipeline connections (3) wells not
         capable of production for mechanical reasons. Behind-pipe reserves are
         expected to be recovered from zones in existing wells, which will
         require additional completion work or future recompletion prior to the
         start of production.

     UNDEVELOPED RESERVES: Undeveloped reserves are expected to be recovered:
     (1) from new wells on undrilled acreage, (2) from deepening existing wells
     to a different reservoir, or (3) where a relatively large expenditure is
     required to (a) recomplete an existing well or (b) install production or
     transportation facilities for primary or improved recovery projects.

                                                    AS OF DECEMBER 31, 1997

                                                    1986-D, LTD.

ATTENTION:  SPECIAL TRANSACTIONS COMMITTEE
            SWIFT ENERGY COMPANY BOARD OF DIRECTORS

At the request of SWIFT ENERGY COMPANY (SWIFT), J. R. BUTLER AND COMPANY
(JRBCo) has conducted an evaluation audit of the hydrocarbon reserves and
future net cash flow as of December 31, 1997, associated with 44 Acquisition
Programs located in the U.S.A.  From this audit, and in consultation with H. J.
Gruy and Associates, Inc. (Gruy), JRBCo has generated its opinion of a "fair
market value" for these properties.  The market values of the properties were
distributed to various partnerships based on ownership to determine the fair
market value of each partnership.  In JRBCo's opinion, utilizing the
distribution of properties into the proper partnerships, the estimated market
value of Swift Energy Income Partners 1986-D, Ltd. is $1,567,013.

Proved reserves in this instance are defined as those estimated volumes of
crude oil, condensate, natural gas, and natural gas liquids that geological and
engineering data demonstrate with reasonable certainty to be commercially
recoverable in the future from known reservoirs under a reasonable price and
cost escalation scenario.  Probable reserves are the estimated quantities of
commercially recoverable hydrocarbons associated with known accumulations which
are based on engineering and geological data similar to those used in the
estimates of proved reserves but, for various reasons, these data lack the
certainty required to classify the reserves as proved.  Possible reserves are
the estimated quantities of commercially recoverable hydrocarbons associated
with known accumulations, which are based on engineering and geological data
which are less complete and less conclusive than the data used in estimates of
probable reserves.  In some cases, economic or regulatory uncertainties may
dictate a probable or possible classification.
<PAGE>   406
Recovery of proved reserves is not without risk but, as generally considered in
the industry, the risk of recovering probable reserves is substantially greater
than that associated with proved categories.  Likewise, possible reserves are
less certain to be recovered than probable.

The reserves and future performance estimates were prepared utilizing standard
petroleum engineering methods.  For properties with sufficient production
history, reserves estimates and rate projections were based primarily on
extrapolation of established performance trends and reconciled, whenever
possible, with volumetric and/or material balance calculations.  For the
non-producing zones and undeveloped locations, reserves were determined by a
combination of volumetric calculations and analogy.  Volumetrically determined
reserves or those determined by analogy are generally subject to greater
qualifications than reserves estimates supported by established production
decline curves and/or material balance calculations.  Determination and
classification of proved reserves were performed (with exception of the use of
escalated prices and costs) in accordance with Securities and Exchange
Commission guidelines.  The definitions used also conform to those promulgated
by the_Society of Petroleum Engineers (SPE) and the World Petroleum Congresses
(WPC).

The reserves and resulting "value estimates" included  in this study are not
exact quantities.  Future conditions may affect the recovery of estimated
reserves, revenue and net cash flow, and all categories of reserves may be
subject to revision and/or reclassification as more performance and well data
become available.  Please note, the reserves estimates made by JRBCo were done
in conjuction with an evaluation audit and are not the result of in-depth field
studies.  In conducting this audit JRBCo reviewed approximately 65% of SWIFT's
proved "PV10  value" (SEC PV10 as of December 31, 1997) for the total 44
Acquisition Programs.

Basic evaluation data were obtained principally from SWIFT and public sources.
The production data available to JRBCo were generally through  August 1997.
Gas and liquid prices were year end (CY 1997) prices as used in SWIFT's
December 31, 1997, SEC cash flow runs.

Estimates of drilling, completion and workover costs were based on information
supplied by SWIFT.  Operating costs were also based on data supplied by SWIFT
in their Lease Operating Statement which was reviewed by JRBCo.  Surface and
well equipment salvage values and well plugging and field abandonment costs
were not considered in the revenue projections.

The estimates of future net cash flow used in market value calculations are
those revenues which should be realized from the sale of the estimated reserves
after deduction of royalties, ad valorem and production taxes, direct operating
costs and required capital expenditures, when applicable.  Future net cash flow
as used in this evaluation is before the deduction of federal income tax.





                                       2
<PAGE>   407
Market value estimates were obtained by applying qualitative risk adjustments
considered appropriate for the various reserves categories and "profit factors"
(as applicable) against discounted future net cash flow values obtained from an
escalated cost and pricing scenario.  Prices, costs and investments were
escalated at 3.5%/year for 15 years.  Final market value estimates were derived
in conjunction and consultation with Gruy.

In the conduct of our review, we have not independently verified the accuracy
and completeness of information and data furnished by SWIFT with respect to
ownership interests, oil and gas production volumes and rates, historical costs
of operation and development, product prices, agreements relating to current
and future operations and sales of production and other information relative to
such things as timing or scheduling of drilling or recompletion operations.

Field inspections were not made in connection with the preparation of this
report.  Furthermore, no judgments were made relative to environmental or other
legal liabilities.

It should be recognized that any oil or gas reserves estimate or forecast of
production and income is a function of engineering and geological
interpretation and judgment.  Such estimates should, therefore, be accepted and
used with the understanding that technical data, economic criteria or
regulatory information obtained subsequent to a study may justify revisions
which could increase or decrease the original estimates of reserves and value.

Neither JRBCo, nor any of its personnel, have any direct or indirect interest
in SWIFT or its affiliates.  JRBCo is an independent consulting firm as
provided in the Standards Pertaining to the Estimating and Auditing of Oil and
Gas Reserves Information promulgated by the Society of Petroleum Engineers.
JRBCo's compensation is not contingent upon the results of its reserves
estimates, cash flow analyses or "market value opinion" which result from its
review of the subject properties.

Swift Energy Company
16825 Northchase Drive, Suite 400
Houston, TX  77060

Attention:  Special Transactions Committee
            Swift Energy Company Board of Directors

Gentlemen:

Pursuant to that certain letter agreement dated February 27, 1998 (the
"Agreement") between the Special Transactions Committee (the "Committee") of
the Board of Directors of Swift Energy Company ("Swift" or the "Company") and
CIBC Oppenheimer Corp. ("CIBC Oppenheimer"), you have retained CIBC Oppenheimer
to prepare an independent financial analysis as to the estimated fair market
value (the "CIBC Oppenheimer Valuation") of various interests (the "Assets") in
oil and gas properties (the "Properties'), which Assets are owned by Swift
Energy Income Partners 1986-D, Ltd. (the "Partnership") of which the Company is
the managing general partner ("General Partner"). CIBC Oppenheimer performed a
similar analysis for 62 other partnerships (the "Partnerships") of which the
Company is the General Partner. It is CIBC Oppenheimer's understanding that the
General Partner has proposed to purchase substantially all of the Partnership's
Assets and, in turn, dissolve and wind up the Partnership. It is also CIBC
Oppenheimer's understanding that the Committee has also retained the reserve
engineering firms of H.J. Gruy & Associates, Inc. and J.R. Butler & Company
(collectively, the "Engineering Consultants") to prepare a separate analysis as
to the estimated fair market value of the Assets (the "Engineering Consultants'
Valuation").

In arriving at the CIBC Oppenheimer Valuation, we, among other things:

         (i)     Reviewed the historical financial returns to the limited
                 partners of the Partnership;

         (ii)    Held discussions with senior management of the Company as to
                 the Partnership's operational and financial prospects;
<PAGE>   409
Swift Energy Company

         (iii)   Held discussions with senior management of the Company
                 regarding the general characteristics of the Properties
                 underlying the Assets, including location, productive
                 geological formations, future development potential and oil
                 and gas marketing arrangements;

         (iv)    Held discussions with the Engineering Consultants regarding
                 the general characteristics of the Properties underlying the
                 Assets, including location, productive geological formations
                 and future development potential;

         (v)     Reviewed the reserve engineering reports supplied to us by the
                 Engineering Consultants and, particularly, reviewed the
                 estimated future net cash flow to be generated from the
                 production of proved reserves of the Properties underlying the
                 Assets discounted to present value using an annual discount
                 rate of 10% (the "PV-10 Value") dated as of December 31, 1997;
                 these amounts were 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 future
                 income tax expense or depreciation, depletion and
                 amortization;

         (vi)    Reviewed the Engineering Consultants' Valuation of the
                 Properties underlying the Assets;

         (vii)   Reviewed historical operating and financial results of the
                 Properties underlying the Assets which included PV-10 Value,
                 proved reserves on a barrel of oil equivalent ("BOE") basis
                 and projected earnings before interest, taxes and
                 depreciation, depletion and amortization ("EBITDA") as
                 prepared by the Engineering Consultants and discussed with
                 senior management of the Company;

         (viii)  Reviewed and analyzed financial terms of similar transactions
                 in which public oil and gas companies liquidated partnerships
                 of which they were the general partner;

         (ix)    Reviewed and analyzed transactions involving the sale of oil
                 and gas companies we deemed comparable to the Partnership(s)
                 individually and collectively and to the Company;

         (x)     Reviewed and analyzed transactions involving the sale of oil
                 and gas properties we deemed comparable to the Properties
                 underlying the Assets;

         (xi)    Reviewed financial and market data for certain public
                 companies we deemed comparable to the Partnership(s)
                 individually and collectively and to the Company; and

         (xii)   Performed such other analyses and reviewed such other
                 information as we deemed appropriate.

In determining the CIBC Oppenheimer Valuation, we have relied upon and assumed,
without independent verification or investigation and at the direction of the
Committee, (i) the accuracy and completeness of all of the financial and other
information available to us from public sources or provided to us by the
Company and their representatives (including the Engineering Consultants), (ii)
that the reserve engineering reports supplied to us by the Engineering
Consultants as described in clause (v) above have been reasonably prepared and
are based on their best business judgment, (iii) that the information with
respect to the Partnership's ownership of the Assets, as provided to the
Engineering Consultants and to us was accurate in all respects, (iv) with
respect to the historical operating and financial results and projections
provided to us as described in clause and (vii) above, that such information
and projections were reasonably prepared and were based on the best currently
available information, estimates and good faith judgment of the Company's
management and their representatives (including the Engineering Consultants).

Not being experts in the geological evaluation of oil and gas reserves, we
have, with your consent, relied without independent verification upon the audit
of the reserve estimates prepared by the Engineering Consultants for the
purpose of estimating fair market value of the Assets. In addition, we have not
made a physical inspection of the Properties underlying the Assets, nor have we
made any independent evaluations, appraisals or inspections of the Company's or
the Partnership's other assets or the Company's or the Partnership's
liabilities (contingent or otherwise). We have not reviewed any relevant
agreements which may exist between the General Partner and the limited partners
governing the Partnership, nor have we considered the effect which the
ownership structure of the Partnership and the terms of the agreements of the
Partnership may have upon the fairness of the consideration offered by any
general partner of the Partnership. We have not reviewed the books and records
of the Partnership and have assumed, with





<PAGE>   411
Swift Energy Company
April 20, 1998
Page 4


your consent, that the Partnership's ownership interests in the Properties
underlying the Assets, as provided to us by you, is true and correct.

The CIBC Oppenheimer Valuation is based upon analyses of the foregoing factors
in light of our assessment of general economic, financial, market and other
conditions and circumstances as of the date of this letter and any changes in
such conditions and circumstances may affect the validity or fairness of the
CIBC Oppenheimer Valuation. CIBC Oppenheimer disclaims any obligations to
update, revise or reaffirm the CIBC Oppenheimer Valuation. The CIBC Oppenheimer
Valuation reflects our estimate of the consideration that could have been
received by the Partnership in a sale of the Assets in an orderly manner in a
private market transaction in which neither buyer nor seller is under any
compunction to complete such transaction.  The CIBC Oppenheimer Valuation falls
within a range of values which we believe, subject to the foregoing conditions,
represent possible fair market value estimates of the Partnership's interest in
the Assets.  The CIBC Oppenheimer Valuation should not be viewed as a guarantee
of the price that a willing buyer might have paid for the Assets.

CIBC Oppenheimer, as part of its investment banking services, is regularly
engaged in the valuation of businesses and securities in connection with
mergers, acquisitions, underwritings, sales and distributions of listed and
unlisted securities and private placements.  CIBC Oppenheimer has provided
certain investment banking and financial advisory services to the Company from
time to time, including acting as co-manager of the Company's Convertible
Subordinated Notes financing in November 1996 and lead manager of the public
offering of the Company's Common Stock in July 1995, and may be involved in
future investment banking activities on behalf of the Company. CIBC Oppenheimer
will also receive a fee upon delivery of this CIBC Oppenheimer Valuation. In
the ordinary course of business, CIBC Oppenheimer actively trades in the equity
securities of the Company for CIBC Oppenheimer's own account and for the
accounts of CIBC Oppenheimer's customers and, accordingly, may at any time hold
a long or short position in such securities.

Based upon and subject to the foregoing, and based upon such other matters as
we consider relevant, it is CIBC Oppenheimer's estimate that the value of Swift
Energy Income Partners 1986-D, Ltd. interest in the Assets as of the date
hereof is $1,369,233.

This letter is being provided for the use of the Committee in its evaluation of
a possible proposal that the Partnership sell the Assets to the Managing
General Partner and dissolve and wind up its affairs. This letter  is not
intended to confer rights or remedies

upon any stockholder of the Company or any partner of the Partnership and may
not be relied upon by any person or entity other than the Committee. Neither
this letter nor the CIBC Oppenheimer Valuation may be published or otherwise
used or referred to, in whole or part, nor shall any public reference to CIBC
Oppenheimer, this letter or the CIBC Oppenheimer Valuation be made without the
prior written consent of CIBC Oppenheimer; provided, however, that the Company
and the Partnership may include a copy of this letter and a reference to CIBC
Oppenheimer in the proxy statement to be distributed to limited partners of the
Partnership in connection with the solicitation of the approval of the proposal
that the Partnership sell the Assets to the General Partner and dissolve and
wind up its affairs. Neither this letter nor the CIBC Oppenheimer Valuation
constitutes a recommendation to any partner of the Partnership as to how such
partner should vote on or respond to the proposal that the Partnership sell the
Assets to the General Partner and dissolve and wind up its affairs.

Sincerely yours,

CIBC Oppenheimer Corp.

                                        97-003-133

Gentlemen:

At your request, we have made an audit of the reserves and future net cash flow
as of December 31, 1997, prepared by Swift Energy Company ("Swift") for certain
interests in Swift Energy Income Partners 1986-D. This audit has been conducted
according to the standards pertaining to the estimating and auditing of oil and
gas reserve information approved by the Board of Directors of the Society of
Petroleum Engineers on October 30, 1979.  We have reviewed these properties and
where we disagreed with the Swift reserve estimates, Swift revised its
estimates to be in agreement.  The estimated net reserves, future net cash flow
and discounted future net cash flow are summarized by reserve category in Table
1 for both the 100% Fund Level Partnership and the Limited Partnership
Interest.

The discounted future net cash flow is not represented to be the fair market
value of these reserves and the estimated reserves included in this report have
not been adjusted for risk.

The estimated future net cash flow shown is that cash flow which will be
realized from the sale of the estimated net reserves after deduction of
royalties, ad valorem and production taxes, direct operating costs and required
capital expenditures, when applicable.  Surface and well equipment salvage
values and well plugging and field abandonment costs have not been considered
in the cash flow projections.  Future net cash flow as stated in this report is
before the deduction of state and federal income tax.

In the economic projections, prices, operating costs and development costs
remain constant for the projected life of each lease.

The reserves included in this study are estimates only and should not be
construed as exact quantities.  Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available.  Proved reserves are
estimated in accordance with the definitions contained in Securities and
Exchange Commission Regulation S-X, Rule 4-10 (a).  The definitions are
included in part as Attachment I.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented.  The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December.  Interim production to December 31, 1997, has been
estimated.  No independent well tests, property inspections or audits of
operating expenses were conducted by our staff in conjunction with this study.
We did not verify or determine the extent, character, obligations, status or
liabilities, if any, arising from any current or possible future environmental
liabilities that might be applicable.

Swift Energy Company                  -2-                      February 10, 1998


In order to audit the reserves, costs and future net cash flows shown in this
report, we have relied in part on geological, engineering and economic data
furnished by our client.  Although we have made a best efforts attempt to
acquire all pertinent data and to analyze it carefully with methods accepted by
the petroleum industry, there is no guarantee that the volumes of oil or gas or
the cash flows projected will be realized.

Production rates may be subject to regulation and contract provisions, and may
fluctuate according to market demand or other factors beyond the control of the
operator.  The reserve and cash flow projections presented in this report may
require revision as additional data become available.

We are unrelated to Swift and we have no interest in the properties included in
the information reviewed by us.  In particular:

         1.    We do not own a financial interest in Swift or its oil and gas
               properties.

         2.    Our fee is not contingent on the outcome of our work or report.

         3.    We have not performed other services for or have any other
               relationship with Swift that would affect our independence.

If investments or business decisions are to be made in reliance on these
estimates by anyone other than our client, such person with the approval of our
client is invited to visit our offices at his expense so that he can evaluate
the assumptions made and the completeness and extent of the data available on
which our estimates are based.

Any distribution or publication of this report or any part thereof must include
this letter in its entirety.

                                        Yours very truly,

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                                   SUPPLEMENT

                        JOINT PROXY STATEMENT/PROSPECTUS

                          OFFERING OF COMMON STOCK OF
                              SWIFT ENERGY COMPANY



         For the definition of capitalized terms herein which are not otherwise
defined, see "Glossary" in the Joint Proxy Statement/Prospectus.  Other
discussions which are cross-referenced in this Supplement are contained in the
Joint Proxy Statement/Prospectus, unless otherwise noted.

         Swift Energy Company ("Swift" or the "Company") is the Managing
General Partner ("Managing General Partner") of 63 Texas limited partnerships
(the "Partnerships"), including the Partnership, formed between 1986 and 1994
to invest in producing oil and gas properties.  Swift is asking interest
holders (referred to herein as "Investors") in the Partnership (and similarly
in the other 62 Partnerships) to approve a Proposal to sell all of the
Partnership's oil and gas assets to the Managing General Partner (the
"Proposal") for $2,426,749, which is a purchase price derived by choosing the
higher of two estimates of fair market value of those assets determined by
three independent Appraisers, and adding to that higher number a 7.5% premium.

         If the Proposal is approved by Investors in the Partnership and its
Companion Partnership, after the sale of all of its oil and gas assets the
Partnership will dissolve, wind up and terminate.  The Partnership will receive
cash for its oil and gas assets, which in turn is to be distributed to the
Investors in the Partnership (along with the net of all assets less liabilities
of the Partnership) in accordance with their respective percentage ownership
interests in the Partnership.  If Investors in the Partnership approve the
Proposal, then each Investor can elect, in their sole individual discretion, to
receive shares of Common Stock of the Company (without payment of any brokerage
commissions) instead of some or all of the cash which they are entitled to
receive upon the Partnership's liquidation.

         The reasons for and effects of the Proposals may be different for
investors in each of the Partnerships.  This Supplement has been prepared to
highlight for the Investors in the Partnership the particular risks, effects
and fairness of the Proposal to the Investors in the Partnership and to provide
<PAGE>   419
information on the Partnership to its Investors, in connection with the
solicitation of proxies by the Managing General Partner for use at the Special
Meeting of the Investors in the Partnership in voting upon the Proposal and to
transact such other business as may be properly presented at the Special
Meeting or any adjournments or postponements thereof.

         BOTH THE VOTE UPON THE PROPOSAL AND ANY ELECTION MADE BY AN INDIVIDUAL
INVESTOR TO RECEIVE SHARES OF SWIFT ENERGY COMPANY COMMON STOCK ARE SUBJECT TO
NUMEROUS RISK FACTORS, INCLUDING THOSE HIGHLIGHTED BELOW.  SEE "RISK FACTORS"
IN THIS SUPPLEMENT AND IN THE JOINT PROXY STATEMENT/PROSPECTUS FOR A FULL
DISCUSSION OF ALL RISK FACTORS.

o        Substantial conflicts of interest exist because if the Proposal is
         approved by the Partnership and its Companion Partnership, the
         Managing General Partner will purchase all of the oil and gas assets
         from the Partnership while it serves as its Managing General Partner.

o        The purchase price for the Partnership's Property Interests may not be
         the highest possible price.

o        No independent representative negotiated the terms of the purchase
         price with the Managing General Partner.

o        No fairness opinion was acquired regarding the fairness of the
         purchase price.

o        The Managing General Partner may profit from acquisition of the
         Partnership's oil and gas assets by investing capital in order to
         develop non-producing reserves of the acquired Property Interests and
         possibly through improvements in oil and gas prices.

o        Estimates of distributions to Investors from continuing operations of
         the Partnership for the life of its reserves are higher than amounts
         anticipated to be received if Investors vote in favor of the Proposal.
         See "Special Factors--Fairness of Proposal of Sale of Assets as
         Compared to Continuing Operations."

o        An election by an Investor to receive shares of Swift Common Stock in
         lieu of cash distributable to Investors subjects such Investors to the
         risks of investing in the Company.

                 This Supplement is dated ______________, 1998

<PAGE>   420
                                THE PARTNERSHIP

         The Partnership was formed over six years ago and owns working
interests in producing oil and gas properties in five states in which its
companion partnership, Swift Energy Pension Partners 1992-B, Ltd. ("Companion
Partnership"), formed at approximately the same time and also managed by the
Managing General Partner, owns the non-operating interests. The Partnership had
expended all of its original capital contributions by the end of July 1992.
The Partnership's oil and gas properties are principally natural gas
properties, representing approximately 85% of the Partnership's 1997 production
and approximately 93% of its total proved reserves at December 31, 1997. The
Partnership has, from time to time, performed workovers and recompletions on
wells in which the Partnership has Property Interests, using funds advanced by
the Managing General Partner to perform these operations, which amounts have
been subsequently repaid.  The Partnership owns interest in 315 wells in 18
fields.

         The following table presents information on those fields in which the
Partnership has Property Interests which constitute 10% or more of the
Partnership's PV-10 Value at December 31, 1997.  The Partnership's "PV-10
Value" is the estimated future net cash flows (using unescalated prices) from
production of proved reserves attributed to the Partnership's Property
Interests, discounted to present value at 10% per annum.  Attachment D to this
Supplement is the report dated February 10, 1998 of the audit by H.J. Gruy and
Associates, Inc., Independent Petroleum Consultants, of the oil and gas
reserves underlying the Partnership's Property Interests, and future net cash
flow expected from the production of those reserves as of December 31, 1997,
presented both for the Partnership as a whole and as to those reserves solely
attributable to the Investors in the Partnership.  This report has not been
updated to include the effect of production since year-end 1997.  In estimating
these reserves, the Managing General Partner, in accordance with criteria
prescribed by the Securities and Exchange Commission, has used year-end 1997
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.  The Managing General
Partner is not aware of any favorable or adverse event causing a significant
change in the estimated amount (as set forth in Attachment D hereto, which is
the report of H.J. Gruy and Associates, Inc.) of proved reserves of the
properties in which the Partnership owns an interest has occurred between
December 31, 1997 and the date of this Supplement.

         The information below includes the location of each field in which the
Partnership has an interest, the number of wells and operators, together with
information on the percentage of the Partnership's total PV-10 Value on
December 31, 1997 attributable to each of these fields.  Information is also
provided regarding the percentage of the Partnership's 1997 production (on a
volumetric basis) from each of these fields.  Of the remaining other fields in
which the Partnership owns a Property Interest, eleven of such fields each
comprise less than 1% of the Partnership's PV-10 Value at December 31, 1997,
and the PV-10 Value of each of the other five fields averages less than 4% of
the Partnership's PV-10 Value at the same date.

- --------------

         (1)Proved producing reserves are reserves that can be expected
to be recovered through existing wells with existing equipment and operating
methods.

         (2) Behind-pipe reserves are proved reserves that will not contribute
to cash flows until recompletion projects have been implemented to place them
into production.  The impact of these recompletion projects will also be limited
until the costs of implementation have been recovered.  In general, it is not
appropriate to bring behind-pipe reserves into production until the formation
that is currently producing has been depleted.  Premature recompletions can lead
to permanent reductions in a well's proved reserves.

         (3)Non-developed reserves are reserves that are expected to be 
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion.  Therefore,
significant additional expenditures are usually required before undeveloped
reserves can be produced.

         Attachment Dis the annual reserves audit and independent reserves
report prepared by H.J. Gruy and Associates, Inc. as to the Partnership's
remaining proved oil and gas reserves available for production over a period in
excess of 15 years.  These quantities have been given a value based





                                       4
<PAGE>   422
upon prices for oil and gas at December 31, 1997.  The value is determined
based upon the assumption that these prices will remain in effect over the life
of these reserves.  This value is then discounted at 10% per year to arrive at
the value (in today's dollars) of these revenues ("PV-10 Value").  This PV-10
Value for the Partnership's Property Interests is $3,357,192.  It is also
estimated that $241,771 in future capital costs must be spent to develop the
Partnership's non-producing reserves.

                                  RISK FACTORS

o        Although the fair market value of the Property Interests proposed to
         be purchased from the Partnership by the Managing General Partner was
         based upon a determination by three independent Appraisers, no opinion
         was acquired as to the fairness of the ultimate purchase price, which
         was determined in the Managing General Partner's sole judgment by
         adding a 7.5% premium over the higher of the two fair market value
         estimates for the Partnership's Property Interests determined by the
         Appraisers.  Therefore, the purchase price was not determined on an
         impartial basis by a party not involved in the transaction, and
         another party intent upon purchasing the Property Interests in the
         Partnership might have offered a different purchase price.  There is
         no guarantee that the purchase price represents the highest possible
         price that could be received for the Partnership's Property Interests
         in all circumstances.  It is possible that a higher (or lower) price
         might be received if these assets were sold on another basis, such as
         at auction or in negotiated sales.  Furthermore, the assessment of the
         value of the Partnership's proved non-producing reserves could vary
         widely, given the typical discounting in valuing non-producing
         reserves.

o        The Managing General Partner did not retain an independent
         representative to act on behalf of the Investors in the Partnership in
         structuring and negotiating the terms or price of the Proposal or the
         purchase price.  The price at which it is proposed that the Company
         purchase the Property Interests from the Partnership has not been
         negotiated at arm's length and is subject to significant conflicts of
         interest between the Company acting as the purchaser of such
         properties while serving as the Managing General Partner of the
         Partnership.  If an independent representative had been retained for
         the Partnership, the terms or price might have been different and
         possibly more favorable to Investors.

o        The fair market value (excluding the 7.5% premium) established for the
         Partnership's Property Interests is based upon the Appraisers'
         evaluation of that value.  Year-end 1997 prices, along with other
         current market factors, were used as a starting point for the
         Appraisers' analysis, and prices and costs were then escalated at a
         rate of 3.5% per year over 15 years.  Substantial increases in the
         prices for oil and gas in the future might result in Investors
         receiving higher distributions from continued operations of the
         Partnership, although the effect of any higher prices is somewhat
         limited because the Partnership has already produced a substantial
         majority of its oil and gas reserves.





                                       5
<PAGE>   423
o        In order to effectuate the sale of its Property Interests, the
         Proposal must not only be approved by the Partnership, but a similar
         Proposal must be approved by the Companion Partnership.  This
         requirement exists because of the significant lowering of the value of
         either (i) a working interest burdened by a large non- operating
         interest controlled by a different party, or (ii) a non-operating
         interest in properties the operations of which are controlled by a
         third party.  Therefore, even if the Investors in the Partnership
         approve the Proposal to sell their Property Interests, this may not be
         done without the approval of a similar Proposal by investors in the
         Companion Partnership.  If either Partnership does not approve its
         Proposal, then the Managing General Partner will reassess  the value
         of the Property Interests of each Partnership and attempt to formulate
         a new proposal for the investors in each such Partnership.

o        Investors that are subject to federal income tax on an investment in
         the Partnership are required to recognize gain or loss on the sale of
         oil and gas assets by the Partnership and the subsequent liquidation
         of the Partnership.  The amount and character of the gain or loss
         depends on certain factors specific to individual Investors.  It is
         anticipated that Investors that acquired their interests in the
         original offering and that are subject to federal income tax will
         recognize a loss for federal income tax purposes.  Any tax that may be
         due must be paid even if such Investors choose to acquire Company
         Common Stock with some or all of their proceeds from property sales.
         Investors also should consult their individual tax advisors to
         determine whether they are subject to any state tax.  For a broader
         discussion of the tax consequences, Investors should read "Federal
         Income Tax Consequences of Adoption of the Proposals" in the Joint
         Proxy Statement/Prospectus, and "Summary of Federal Income Tax
         Consequences" in this Supplement.

o        Investors that are Tax Exempt Plans will be subject to taxation on the
         Partnership's sale of property and the liquidation of the Partnership,
         while other Tax Exempt Plans are not expected to be subject to
         taxation on the sale and liquidation.  It is anticipated that Tax
         Exempt Plans that acquired their interests in the original offering
         will recognize a loss for federal income tax purposes.    See "Summary
         of Federal Income Tax Consequences--Tax Treatment of Tax Exempt
         Plans--Debt-Financed Property" in this Supplement.

o        As currently proposed, Investors that subscribe for Company Common
         Stock pursuant to this Offering may not receive some or all of the
         cash which otherwise would be distributed to them as part of the
         liquidating distribution of their Partnership.  The amount of any cash
         liquidating distribution they actually receive depends upon the
         purchase price to be paid for any Company Common Stock they elect to
         and are entitled to receive pursuant to the terms of this Offering.
         For federal income tax purposes, Investors subscribing for shares of
         Company Common Stock will be treated as though they had purchased
         those shares for cash, even though they never had actual possession of
         the cash used to acquire the shares.  Additionally, the fact that such
         Investors elect to acquire Company Common Stock rather than receive
         cash in liquidation of their Partnership interests will not affect the
         federal income tax consequences attending the liquidation of their
         Partnership interests.  Because





                                       6
<PAGE>   424
         the purchase of shares of Company Common Stock will reduce the cash
         received by Investors upon the Partnership's liquidation, to the
         extent that Investors owe federal income tax as a result of the
         liquidation, they may not receive sufficient cash to pay some or all
         of any tax they may owe on the liquidation.  Such Investors owing tax
         as a result of the liquidation will have to pay such tax from sources
         other than any cash liquidating distribution from the Partnership.

See "Risk Factors" in the Joint Proxy Statement/Prospectus.


                             CONFLICTS OF INTEREST

         There are substantial conflicts of interest which exist by virtue of
the Managing General Partner acting in that capacity on behalf of the
Partnership while at the same time acting as the proposed purchaser of all of
the oil and gas assets of the Partnership.  These conflicts of interest are
discussed below.

o        The terms of the Proposal are established by the Company which is also
         the Managing General Partner of the Partnership.

o        Neither the Managing General Partner nor a majority of its independent
         directors retained an independent representative to act on behalf of
         the Partnership's Investors for the purposes of negotiating the terms
         upon which any such sale to the Managing General Partner would be made
         or for the preparation of a report concerning the fairness of the
         entire transaction.

See "Summary--Conflicts of Interest" and "Conflicts of Interests" in the Joint
Proxy Statement/Prospectus.


                                SPECIAL FACTORS

BACKGROUND AND PURPOSE OF THE PROPOSAL

         A number of factors have led to the decision of the Company in its
capacity as Managing  General Partner to solicit approval of the Proposal by
Investors in the Partnership.  The general improvement in the prices for
natural gas over the last several years, relative to such prices in the
mid-1990's, make this an appropriate time, especially in light of the high
percentage of the Partnership's reserves comprised of natural gas, to consider
the Proposal to sell the Partnership's Property Interests.  The structure being
proposed, which involves the sale of the Partnership's oil and gas assets to
the Managing General Partner, is being submitted for approval by Investors in
an attempt to realize the highest value for those assets.  For the reasons set
out below, the Managing General Partner believes that the Proposal is fair to
Investors in the Partnership, given





                                       7
<PAGE>   425
that the purchase price for these assets has been determined by taking the
higher of two fair market value estimates by three independent Appraisers and
adding to it a 7.5% premium.

         Approval of the Proposal will have the following effects:

1.       The Managing General Partner will purchase all of the oil and gas
         assets of the Partnership, provided its Companion Partnership has
         approved its proposal.

2.       When the Partnership sells all of its oil and gas assets, it will be
         required to liquidate and distribute its remaining assets (principally
         the cash proceeds from the sale) to its partners (including the
         general partners) in accordance with their respective ownership
         interests in the Partnership.

3.       Investors will be given the option of electing to receive shares of
         Swift Common Stock, in amounts that they choose on an individual
         basis, in lieu of some or all of the cash they would be entitled to
         receive upon the Partnership's liquidation.

4.       Investors in the Partnership will be taxed on the sale of the
         Partnership's oil and gas assets, although such sale is expected to
         result in a taxable loss to Investors that acquired their interests in
         the original offering.

PROPOSED PURCHASE PRICE

         As discussed in greater detail below, the Petroleum Engineering
Consultants estimated that the aggregate fair market value of the Partnership's
Property Interests as of December 31, 1997 is $2,257,441.  CIBC Oppenheimer
estimated a fair market value of the same Property Interests at the same date
of $2,118,171.  The Special Transactions Committee chose the higher of these
two determinations as the "Fair Market Value" for the purchase of these
interests and the Board of Directors of the Company determined to pay a 7.5%
premium ($169,308) above the Fair Market Value to purchase the Partnership's
Property Interests, resulting in a purchase price of $2,426,749.  This compares
to the total purchase price for all of the oil and gas assets of all 63
Partnerships which are considering similar proposals of approximately $81
million.  The valuation estimates of the Appraisers are attached to this
Supplement and incorporated herein by reference as follows:  Attachment A is
the fair market value estimate of H.J. Gruy and Associates, Inc., Attachment B
is the fair market value estimate of J.R. Butler and Company, and Attachment C
is the fair market value estimate of CIBC Oppenheimer Corp.  The PV-10 Value
prepared on an annual basis by H.J. Gruy of the same Property Interests as of
the same date is $3,357,192.





                                       8
<PAGE>   426
REASONS FOR THE PROPOSAL

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

         Current Liquidating Distribution Lowers Volatility Risk.  The
Partnership has been in existence for over six years.  The Managing General
Partner believes that the ability to receive the estimated liquidating
distribution in one lump sum at this time, rather than in smaller amounts over
a longer period, is one of the benefits of the Proposal, without the risk of
such distributions being negatively affected by oil and gas price decreases and
the inherent risks associated with geological, engineering and operational
matters.  It is also the Managing General Partner's belief that improvements
over the last several years in the level of gas prices, relative to such prices
in the mid-1990s, makes this an appropriate time to consider the sale of the
Partnership's Property Interests and increases the likelihood of maximizing the
value of the Partnership's assets, although the future prices and market
volatility cannot be predicted with any accuracy.

         Decreasing Cash Flow While Expenses Continue.  The Partnership's oil
and gas reserves are expected to continue to decline as remaining reserves are
produced.  Declines in well production are based principally upon the maturity
of the wells, not on market factors.  These declines will continue to occur
while oil field overhead and operating costs ($80,445 in 1997) and direct and
general and administrative expenses ($160,174 in 1997) continue, which are
relatively fixed amounts.  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.  By accelerating the liquidation of the Partnership, those future
administrative costs will be avoided by the Partnership.

         Interest Holders' Tax Reporting.  Each Investor will continue to have
an income tax reporting obligation with respect to his SDIs as long as the
Partnership continues to exist.  There is no trading market for the SDIs, so
Investors generally are unable to dispose of their SDIs.  See "Partnership
Business and Financial Condition--No Trading Market" in this Supplement.
Following the sale of the Partnership's Property Interests and dissolution of
the Partnership, Investors will realize gain or loss under federal income tax
laws.  See "Summary of Federal Income Tax Consequences--Taxable Gain or Loss
upon Sale of Properties" in this Supplement.  Thereafter, Investors will have
no further tax reporting obligations with respect to the Partnership.  See
"Summary of Federal Income Tax Consequences--Liquidation of the Partnership" in
this Supplement.

See "Summary--Background of the Proposals," "--Purpose and Effect of the
Proposals," "--Reasons for the Proposals" and "--Managing General Partner's
Recommendations" in the Joint Proxy Statement/Prospectus.

COLLECTIVE ANALYSIS OF PURCHASE PRICE; PREMIUM OVER FAIR MARKET VALUE

         The Special Transactions Committee selected H.J. Gruy and Associates,
Inc. ("H.J. Gruy" or "Gruy"), J.R. Butler and Company ("J.R. Butler" or
"Butler"), which are both petroleum engineering consultants, and CIBC
Oppenheimer Corp.  ("CIBC Oppenheimer"), an investment banking firm, to
estimate the fair market value of the Property Interests of each of the
Partnerships.  Collectively, H.J. Gruy, J.R. Butler and CIBC Oppenheimer are
referred to herein as the "Appraisers," and H.J. Gruy and J.R. Butler together
are sometimes referred to herein as the "Petroleum Engineering Consultants."

         The following subsections of the "Special Factors" section of the
Joint Proxy Statement/Prospectus should be reviewed for information concerning
the selection and qualification of the Appraisers and the parameters of the
valuation estimates: "Independent Appraisal of the Fair Market Value of
Property Interests of the Partnerships," "Qualification of Appraisers," and
"Fair Market Value."

         The Petroleum Engineering Consultants arrived at a fair market
valuation estimate based upon appraisal of the projected discounted cash flow
from its various Property Interests.  On the other hand, the investment banking
firm of CIBC Oppenheimer made a valuation estimate of the Partnership's
Property Interests based upon the application of multiple quantitative and
qualitative factors.  The quantitative factors include, among other things, a
review of relevant valuation criteria from comparable acquisitions of both oil
and gas properties and companies that are predominantly active in the oil and
gas industry, and a review of valuation criteria for relevant publicly traded
oil and gas companies.

         The process used by the Petroleum Engineering Consultants in preparing
their valuation estimate is discussed at length in the Joint Proxy
Statement/Prospectus under "Special Factors--Valuation by Petroleum Engineering
Consultants." As described therein, the Petroleum Engineering Consultants
individually audited the estimate of present value of future net cash flows
from the 44 property groups in which Property Interests are owned by the
Partnerships to whom similar proposals are being made to sell all of their oil
and gas assets and liquidate their Partnerships.  The Partnership owns Property
Interests in six of these property groups.  The Petroleum Engineering
Consultants began their analysis based upon the year-end 1997 PV-10 Value of
each property audited by H.J. Gruy and together they re-evaluated reserve
quantities, projected operating costs and cash flows.  The present value of
this reserves analysis was then derived by escalating year-end 1997 prices
($2.38 per MMBtu and $16.00 per barrel before adjustments for Btu content for
gas and gravity variances for oil as well as transportation charges and
geographic location) and costs by 3.5% per year for 15 years.  This present
value was then adjusted for various individual field risks and risk adjustments
of proved non- producing reserves and proved undeveloped reserves.  The result
of this collective analysis by the Petroleum Consulting Engineers was their
estimation that the fair market value of Property Interests owned by the
Partnership was $2,257,441 as of December 31, 1997.

         The methodology used by CIBC Oppenheimer to prepare its valuation
estimate is discussed at length under "Special Factors--Valuation by CIBC
Oppenheimer" in the Joint Proxy Statement/Prospectus.  CIBC Oppenheimer's
evaluation of the Partnership's Property Interests began with the PV-10 Value
of each property group, as calculated by Swift and audited by H.J. Gruy which
Gruy report dated February 10, 1998 is Attachment D to this Supplement.  CIBC
Oppenheimer then divided the property groups into two categories.  Those
property groups with reserves consisting primarily of proved developed
producing reserves were placed in the "Conventional Case" category.  Those
property groups with significant proved developed non-producing or undeveloped
reserves were placed in the "Non-Conventional Case" category.  The Partnership
has interests in property groups which were in only the "Conventional Case"
category.  [VARIABLE SENTENCE (CODED FIELD) RE EACH P'SHIP'S CASE CATEGORY]
CIBC Oppenheimer then valued each property group by applying the multiples
discussed under "Special Factors--Valuation by CIBC Oppenheimer--Valuation
Multiples" in the Joint Proxy Statement/Prospectus to each property group's
PV-10 Value, proved reserves on a BOE basis, and projected 1998 EBIDTA.  A
separate set of multiples was used for property groups in the Conventional Case
category and the Non-Conventional Case category, respectively.  This provided
CIBC Oppenheimer with three estimated values for each property group.  The
average of these three values yielded CIBC Oppenheimer's estimation of the fair
market value of each property group.  CIBC Oppenheimer then allocated the
appropriate portion of each property group's estimated fair market value to the
Partnership based upon the Partnership's Property Interests in each property
group.  The result of this analysis by CIBC Oppenheimer was an estimation that
the fair market value of the Partnership's Property Interests was $2,118,171 on
December 31, 1997.

         The Special Transactions Committee has determined that, in keeping
with the definition of Fair Market Value, the higher of these two estimations
of fair market value, or $2,257,441, represents the Fair Market Value of the
Partnership's Property Interests.  Accordingly, the fair market value
estimation of the Petroleum Consulting Engineers and the fair market value
determined by CIBC Oppenheimer were compared to each other and the higher of
the two was chosen as the Fair Market Value of the Property Interests owned by
the Partnership.  The variation between the fair market value estimate of the
Partnership's Property Interests prepared by the Petroleum Consulting
Engineers, on one hand, and CIBC Oppenheimer on the other was 7%.

DETERMINATION OF PREMIUM OVER FAIR MARKET VALUE BY THE COMPANY

         The Special Transactions Committee presented its recommendation to the
Board of Directors of the Company as to the Fair Market Value of the Property
Interests of the Partnership.  The Board of Directors of the Company then
determined that paying a 7.5% premium over the Fair Market Value of the
Partnership's Property Interests was appropriate and fair based upon the
factors and for the reasons discussed below.  Because the Company has served as
Managing General Partner of the Partnership for over six years, it is
intimately familiar with the Property Interests owned by the Partnership.  The
Managing General Partner believes that if the Property Interests were to be
sold to a third party purchaser that was not equally familiar with those
interests, it is likely that the purchaser would discount the purchase price to
account for that lack





                                       11
<PAGE>   429
of familiarity and associated risks.  If these interests are purchased by the
Company, then the additional cost and personnel often inherent in making a
property acquisition are not required, because the files and deed records
already exist in the Company's lease and computer systems, and conveyance and
title issues do not exist.

         In the judgment of the Company, the purchase of the Partnership's
Property Interests together with interests in many of the same properties owned
by other Partnerships at approximately the same time will result in
efficiencies to the Company in aggregating such interests.  Swift's long-term
knowledge of the risks involved in these properties means that it is in a
better position to evaluate these risks than third parties.

         Based upon the Company's experience in purchasing properties, the lack
of additional costs often incurred in purchasing oil and gas properties in
which the purchaser has owned no interest, and the Company's intimate
familiarity with these Property Interests and consequent ability to evaluate
acquisition risks, it was deemed appropriate to pay a premium representing the
benefit to the Company arising from these factors.

         The amount of the premium principally was based upon management's
experience in purchasing properties which contain both producing reserves and
drilling potential, without any statistical or analytical study prepared by the
Company in the course of determining the amount of this premium.  Since 1979,
the Company, on behalf of itself and others, has gained a wide range of
experience with the valuation of oil and gas properties and the prices for
their purchase and sale, having purchased $478 million of such properties in
129 separate transactions.  Other purchasers might have determined it
inappropriate to pay  a premium, or if so, to pay a premium based upon other
factors or in a different amount.  Because there has been no independent third
party involved in the decision to pay this premium or in the determination of
its amount, and no fairness opinion has been requested regarding this premium,
conflicts of interest exist in its determination, although the Managing General
Partner believes, based upon its knowledge of the oil and gas industry, its
knowledge of the properties involved, its experience in purchasing and selling
oil and gas properties, and the benefits from purchasing the Property Interests
which are particular to the Company, that the amount being offered to the
Partnership to purchase its Property Interests is fair.

"SPECIAL FACTORS" SECTION IN THE JOINT PROXY STATEMENT/PROSPECTUS

         The Special Factors section in the Joint Proxy Statement/Prospectus
contains a full discussion of the determination of the purchase price proposed
to be paid by the Managing General Partner to purchase the Partnership's
Property Interests.  In addition to those topics discussed at length in this
Supplement, the Joint Proxy Statement/Prospectus addresses alternative
transactions that were considered but not proposed for the Partnership and the
other 62 partnerships to whom similar proposals are being made simultaneously.
It also contains information regarding the prior relationships between the
Appraisers, the Partnerships and the Managing General Partner, the absence of a
request that an independent representative negotiate the terms of the purchase
of the

Partnership's Property Interests by the Managing General Partner, the manner in
which expenses are to be borne for the transaction, the Managing General
Partner's source of funds to purchase the Partnership's Property Interests, and
the benefits that the Managing General Partner would receive from purchasing
such Property Interests.

ESTIMATES OF LIQUIDATING NET CASH DISTRIBUTION AMOUNT IF THE PROPOSAL IS
APPROVED

         The purchase price proposed to be paid to the Partnership for its oil
and gas assets is the Fair Market Value plus the purchase premium.  As is the
case with all oil and gas properties purchases, the purchase is proposed to be
made as of the date which the properties were evaluated (in this case December
31, 1997).  A portion of the reserves used to establish the Fair Market Value
has been produced during 1998.  Most of the net revenue received by the
Partnership from the sale of such production since the proposed purchase date
(December 31, 1997) has been distributed to the partners during 1998 through
quarterly cash distributions or, to the extent not already distributed, will be
distributed as part of the Partnership's liquidating distribution.
Accordingly, the actual purchase price which will be paid to the Partnership
will be reduced by the amount of net production revenue received by the
Partnership after December 31, 1997.

         Set forth in the table below are estimated net proceeds that the
Partnership may realize from the sale of the Partnership's Property Interests,
estimated expenses of the related dissolution and liquidation of the
Partnership and estimated interim net cash distributions from January 1, 1998
until September 30, 1998, resulting in an estimate of the amount of net cash
distributions available for partners as a result of such sale.

(8)      Under the terms of the offer of Swift Common Stock to Eligible
         Purchasers, if the Investors in the Partnership approve the Proposal
         and its Companion Partnership approves a similar Proposal, such
         Investors will be Eligible Purchasers.  The minimum number of shares
         which can be purchased by an Eligible Purchaser is a round lot of 100
         shares.  Based upon estimated net cash distribution of $0.19 per $1.00
         SDI, the number of SDIs shown above is the minimum number of SDIs
         which it will be necessary for an Investor to own in order to purchase
         a minimum 100 share round lot of Swift Common Stock without providing
         any additional funds from other sources.  This calculation is based
         upon an assumed purchase price of Swift Common Stock of $18.00 per
         share (which is the same price upon which the proforma financial
         statements contained in the Joint Proxy Statement/Prospectus are
         based) for an aggregate purchase price for 100 shares of Swift Common
         Stock of $1,800.  The minimum number of Units shown is subject to
         change, based upon the price for Swift Common Stock at a future date
         as specified under "Offering of Shares of Swift Energy Company Common
         Stock if Investors Approve the Proposal--Offer of Swift Common
         Stock--Purchase Price" in this Supplement.  However, if an Eligible
         Purchaser has interests in more than one Partnership, the cash
         distributions he will be entitled to receive may be aggregated to meet
         the minimum share purchase requirement of a round lot of 100 shares.

ESTIMATES OF NET CASH DISTRIBUTIONS AVAILABLE FROM CONTINUED OPERATIONS

         If the Partnership were to retain its Property Interests until they
have reached their economic limit, the table below estimates the return to
Investors, without regard to amounts distributable to the General Partners,
discounted to present value, based upon 1997 year-end pricing without
escalation and upon the discount assumptions used above.  The estimates of the
present value of future net cash distributions have been further reduced by
estimates of 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.
The following estimated future net revenues do not take into account any
additional costs which might be incurred by the Partnership due to needed
future maintenance or remedial work on the properties in which the Partnership
has an interest, which would reduce such net revenues.

         Business and Financial Condition" in this Supplement.

         The proceeds of all sales, to the extent available for net cash
distribution, are to be distributed to the partners in accordance with the
Partnership's limited partnership agreement.  The amounts finally distributed
will depend on the actual sales prices received for the Partnership assets,
results of operations until liquidation of the Partnership, final costs and
other contingencies and circumstances.

FAIRNESS OF PROPOSED SALE OF ASSETS TO THE MANAGING GENERAL PARTNER
   AS COMPARED TO CONTINUING OPERATIONS

         Based on the above tables, it is estimated that an Investor could
expect to receive $0.19 per $1.00 SDI upon the sale of the Partnership's
Property Interests as of September 30, 1998.  In comparison, it is estimated
that an Investor could expect to receive $0.24 per $1.00 SDI, discounted to
present value at 10% per annum ($0.41 per $1.00 SDI on an undiscounted basis)
if the Partnership continued operations.  The Managing General Partner believes
that the Proposal to sell the Partnership's Property Interest as compared to
continuing operations is fair to Investors for the reasons discussed below.

         Although the estimates contained in the two tables above show that
estimated net cash distributions to Investors (based on net present value) from
continued operations would be approximately 26% higher than estimated net cash
distributions from selling the Partnership's Property Interests and liquidating
the Partnership currently, the Managing General Partner believes there is a
substantial advantage in receiving the liquidating net cash distribution in one
lump sum at this time. The estimates of net cash distributions from continued
operations are based upon 1997 year- end pricing.  It is highly likely that
over such a long period of time, oil and gas prices will vary often and
possibly widely, as has been demonstrated historically, from the prices used to
prepare these estimates.  Continued operations over such a long period of time
subject Investors to the risk of receiving lower levels of net cash
distributions if oil and gas prices over this period are lower on average than
those used in preparing the estimates of net cash distributions from continued
operations.  Continued operations also subject Investors' potential net cash
distributions 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.  The Managing General Partner also believes that there
is an advantage to Investors taking any funds to be received upon liquidation
and redeploying those assets in other investments, rather than continuing to
receive decreasing levels of net cash distributions over such a long period of
time.

         Because there is no active trading market for SDIs in the Partnership,
the only other comparable value for SDIs is the 1997 "SDI Value," which, as
explained below, is the amount calculated on an annual basis under the terms of
the limited partnership agreement at which the Managing General Partner can
offer to repurchase SDIs from Investors.  As of January 1, 1997, this "SDI
Value" was $0.36 per $1.00 SDI.





                                       16
<PAGE>   434
In 1997, the Investors received net cash distributions of $0.10 per $1.00 SDI,
and are estimated to receive another $0.06 per $1.00 SDI before September 30,
1998, which converts to a comparable value of $0.20 per $1.00 SDI before any
adjustments to quantities of reserves or oil and gas prices during this almost
two year period.  Under the terms set out in the partnership agreement, each
year the Managing General Partner is required to furnish to Investors the SDI
Value, and Investors have the right to present their SDIs for purchase by the
Managing General Partner for the SDI Value.  The SDI Value amount is determined
on an entirely different basis than the estimates of fair market value by the
Appraisers.  Furthermore, the SDI Value was calculated over one year ago, with
a valuation date of January 1, 1997, as opposed to the date for assessment of
Fair Market Value being December 31, 1997. Because of significant changes in
oil and gas prices within a year's time, in addition to the changes in reserve
quantities during that period, the calculation of SDI Value as of January 1,
1997, and the Fair Market Value as of December 31, 1997, are not comparable.
SDI Value is derived by taking 70% of the present value of proved oil and gas
reserves (discounted at 10% per annum) calculated on an escalated pricing
basis, plus cash and accounts receivable less outstanding debts and obligations
of the Partnership.

         Although the PV-10 Value of the Partnership's Property Interests is
higher than the purchase price proposed if the Proposal is approved, the
Managing General Partner does not believe that the PV-10 Value accurately
reflects the amount that oil and gas industry members are currently paying to
purchase producing properties on the open market.

FAIRNESS OF PROPOSED SALE

         The Managing General Partner believes that the entire transaction
related to the Proposals involving the proposed method of sales of the
Partnerships' Property Interests is fair to Investors for the following
reasons, without giving any particular weight to any reason:

         1.      The Managing General Partner believes that the most important
                 element of the Proposal is the determination of the Fair
                 Market Value of the Partnership's Property Interests.  The
                 price to be paid by the Company to purchase the Partnership's
                 Property Interests was determined in the Managing General
                 Partner's sole judgment by adding a 7.5% premium to the higher
                 of the two estimates by the Appraisers of the fair market
                 value of the Partnership's Property Interests.  Two of the
                 three Appraisers are qualified independent petroleum
                 engineering firms and the other is an investment banking firm.
                 The factors and methods used by the Appraisers in determining
                 Fair Market Value are discussed in detail under "Special
                 Factors--Independent Appraisal of the Fair Market Value of
                 Property Interests of the Partnerships", "--Fair Market
                 Value," "--Valuation by Petroleum Engineering Consultants,"
                 "--Valuation by CIBC Oppenheimer" and "--Collective Analysis
                 of Purchase Price" in the Joint Proxy Statement/Prospectus.

         2.      No transaction will take place unless the Proposal is approved
                 by Investors holding at least a majority of the interests in
                 such Partnership (without any vote by the Managing General
                 Partner) and a similar Proposal is approved by the
                 Partnership's Companion Partnership.

         3.      The Special Transactions Committee made the determination as
                 to the retention of the Appraisers and approved the fair
                 market value estimates provided by the Appraisers and
                 recommended the reports of the Appraisers to the Board of
                 Directors of the Company.





                                       17
<PAGE>   435
                 The Special Transactions Committee is comprised solely of
                 independent directors of the Company.

         4.      If the Proposals are approved by investors in any of the 63
                 Partnerships considering similar proposals, it is likely that
                 the Managing General Partner will expend the capital necessary
                 to develop non- producing reserves on the Property Interests
                 purchased by the Managing General Partner from those
                 Partnerships.  If all of the Property Interests which are the
                 subject of the Proposals are acquired by the Company, such
                 Property Interests in the aggregate will constitute less than
                 20% of the Company's total assets.  Because the Managing
                 General Partner would be the beneficiary of any such increase
                 in value, the Managing General Partner is hereby offering to
                 Eligible Purchasers the opportunity to purchase up to
                 2,500,000 shares of Common Stock of the Company.  There is no
                 requirement that any purchase of Swift's Common Stock be made.
                 See "Offer of Swift Common Stock" below.

         5.      In structuring the Proposal and related transactions, the
                 Managing General Partner considered that any sale of
                 Partnership Property Interests, whether to the Managing
                 General Partner or to a third party, would be a taxable
                 transaction.  Thus, if an Investor subject to federal income
                 tax chooses to use the proceeds received on liquidation of
                 that Investor's Partnership to purchase Swift Common Stock,
                 tax will still have to be paid on any taxable income resulting
                 from the Partnership's sale of oil and gas assets, without
                 regard to whether the Investor has cash proceeds remaining
                 from his liquidating distribution to pay such tax. Investors
                 that purchased their interests in the original offering,
                 however, are not expected to recognize gain on the sale.

         The determination by the Special Transactions Committee to pay the
purchase premium, the independent Appraisers' determination of the fair market
value of the properties, and the payment of a 7.5% premium do not necessarily
remove the substantial conflicts of interest which exist in the transaction
between the Company serving as Managing General Partner of the Partnership and
also acting as the purchaser of the Property Interests from the Partnership.
No fairness opinion was requested or received regarding the ultimate purchase
price to be paid by the Company to purchase the Partnership's oil and gas
assets.  The Company determined that rather than setting the purchase price for
Partnership Property Interests itself, it would be preferable to instead
request three different independent Appraisers to determine two sets of fair
market values at which such Property Interests should be purchased and then to
choose the higher of those two values.  The Managing General Partner believes
that when the Appraisers rendered their opinions as to the "fair market value"
of the Partnership's Property Interests, inherent within their appraisal
opinions were the Appraisers' determination that these "fair market values"
were "fair," or such determinations would not have been made.  Consequently, no
independent fairness opinion was requested regarding "fair market values" or
upon the premium.  The Managing General Partner believes that adding a 7.5%
premium to the highest of the two fair market value determinations made by the
three Appraisers only serves to increase the amount to be paid to Investors
upon liquidation of the Partnership and does not require a separate fairness
opinion.  The determination by a third party purchaser as to the purchase price
might be more or less than that being proposed by the Managing General Partner
as a purchase price for these Property Interests.

         The determination to submit the Proposal to Investors in which the
Company would purchase the Property Interests of the Partnership was deemed by
the Managing General Partner to be the most





                                       18
<PAGE>   436
appropriate time and method for liquidation of the Partnership.  This decision
was made in light of full consideration by the Managing General Partner of its
fiduciary obligations to Investors.  Furthermore, the decision to use three
Appraisers, rather than one, and to have the Appraisers actually set the fair
market value for purchase of the Property Interests, rather than the Managing
General Partner setting that value and requesting a fairness opinion, were
based upon the Managing General Partner's consideration of the substantial
conflicts of interest which exist in the transactions covered hereby.

See "Special Factors--Fairness of Proposed Sale" in the Joint Proxy
Statement/Prospectus.

MANAGING GENERAL PARTNER BENEFITS

         Benefits accruing to the Company resulting from the purchase of the
Partnerships' Property Interests include the following:  the Managing General
Partner will share the benefits available to Investors through liquidating its
Partnership interests (including both its general partner interests and any
SDIs it owns) and receiving the same value of those interests as Investors.
Additionally, the Company intends to profit from purchasing the Partnership's
Property Interests through a return on capital used to purchase those oil and
gas assets and invest in their development.  By purchasing the Partnership's
Property Interests itself, the Managing General Partner will be able to
maintain its position as operator of certain properties in which the
Partnership owns an interest.  Consequently, the Managing General Partner would
continue to receive operating fees as operator of those properties.  The sale
of the Partnership's Property Interests to the Managing General Partner will
have no effect or an inconsequential effect on the Managing General Partner's
net book value and net earnings.  However, the purchase of all of the oil and
gas assets of the Partnerships would increase the Company's proved reserves,
cash flow and total assets by a significant amount.  Lastly, if individual
Investors which approve the Proposal elect to purchase Company Common Stock,
rather than receiving cash upon liquidation of the Partnership, the Company
will benefit by using stock to pay the purchase price, rather than using its
available cash resources or borrowing facilities.

See "Special Factors--Managing General Partner Benefits" in the Joint Proxy
Statement/Prospectus.

SIMULTANEOUS PROPOSALS TO COMPANION PARTNERSHIPS

         Simultaneous Proposals are being made to investors in the
Partnership's Companion Partnership.  If both the Partnership and its Companion
Partnership do not approve their respective Proposals, it is likely to affect
the ability of the Partnership to consummate the sale of its Property
Interests.  Although the Investors in the Partnership may desire to sell their
Property Interests, the separation of the working interest and the
non-operating interests in the same properties may affect the salability of
those interests on a permanent basis.  If, for example, the Partnership
approves the Proposal but the Companion Partnership does not, the value of a
working interest burdened by a large non- operating interest is likely to be
lowered significantly.  [VARIABLE FOR REVERSAL TEMPLATE: IF, FOR EXAMPLE, THE
PARTNERSHIP APPROVES THE PROPOSAL BUT THE COMPANION PARTNERSHIP DOES NOT, THE
VALUE OF A NON-OPERATING INTEREST IS LIKELY TO BE NEGATIVELY AFFECTED BY THE
LACK OF CONTROL OVER OPERATIONS.]  If the Partnership's Companion Partnership
does not approve its Proposal, then the Managing General Partner will advise
the Investors in the Partnership.  If the investors in the Partnership's
Companion Partnership do not vote in favor of its Proposal, then it is likely
that the Partnership will continue operations and will produce its reserves
until depletion, with steadily decreasing rates of cash flow, and consequently
steadily decreasing amounts of cash distributions to the Investors.

                             VOTING ON THE PROPOSAL

         The Joint Proxy Statement/Prospectus and the Proxy enclosed with this
Supplement are being provided for use at the Special Meeting of Investors of
the Partnership and at any adjournment or postponement of such meeting (the
"Meeting") to be held at 16825 Northchase Drive, Houston, Texas at 4:00 p.m.
Central Time on ______, __________, 1998.  The Meeting is being called for the
purpose of considering and voting upon the Proposal to sell all of the oil and
gas assets of the Partnership to the Company, and to dissolve, wind up and
terminate the Partnership, and to transact such other business as may be
properly presented at the Meeting, all in accordance with the terms and
provisions of the Partnership's limited partnership agreement (the "Partnership
Agreement") and the Texas Revised Limited Partnership Act (the "Texas Act").
This Joint Proxy Statement/Prospectus and enclosed Form of Proxy are first
being mailed to Investors on or about ____________, 1998.

          Pursuant to the terms of the Partnership Agreement, the Partnership,
if not terminated earlier, will continue in being through December 31, 2021, at
which point it will terminate automatically.

         Under the Partnership Agreement, the Proposal must be approved by the
affirmative vote of Investors holding more than 50% of the SDIs in the
Partnership as of the Record Date (defined below).  Therefore, an abstention by
an Investor will have the same effect as a vote against the Proposal.  The
solicitations are being made for votes in favor of the Proposal (which will
result in liquidation and dissolution of the Partnership).  As of the Record
Date, 8,398,878 SDIs were outstanding and held by record holders (excluding the
SDIs held by the Managing General Partner as discussed below).  Accordingly,
the affirmative vote of holders of at least 4,199,440 SDIs is required to
approve the Proposal.  Each Investor appearing on the records of the
Partnership as of ______, 1998 (the "Record Date") is entitled to notice of the
Meeting and is entitled to one vote for each SDI held by such Investor.  VJM
Corporation, a California corporation, is the Special General Partner of the
Partnership, and owns a 0.75% interest in the Partnership as a general partner,
but owns no SDIs.  The Managing General Partner owns a general partner interest
in the Partnership of 14.25%.  Additionally, the Managing General Partner owns
232,500 outstanding SDIs in the Partnership, which ownership results from the
Managing General Partner's purchase over the life of the Partnership of SDIs
from Investors under the right of presentment, contained in the Partnership
Agreement.  Under the Partnership Agreement, the Managing General Partner may
not vote any SDIs owned by it for matters such as the Proposal.  The Managing
General Partner's non-vote, in contrast to abstention by Investors, will not
affect the outcome, because for purposes of adopting the Proposal, its SDIs are
excluded from the total number of voting SDIs.

VOTE REQUIRED

         The actual proxy to be used to register the vote on the Proposal
before you is the separate green sheet of paper included with this Supplement
and Joint Proxy Statement/Prospectus.  PLEASE USE THE GREEN PROXY TO CAST YOUR
VOTE ON THE PROPOSAL.

         If a proxy is properly signed and is not revoked by an Investor, the
SDIs it represents will be voted in accordance with the instructions of the
Investor.  If no specific instructions are given, the SDIs will be voted FOR
the Proposal.  An Investor may revoke his proxy at any time before it is voted
at the Meeting.  Any Investor who attends the Meeting and wishes to vote in
person may revoke his proxy at that time.  Otherwise, an Investor must advise
the Managing General Partner of revocation of his proxy in writing,





                                       20
<PAGE>   438
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.

SOLICITATION

         The solicitation is being made by the Partnership.  The Partnership
will bear the costs of the preparation of the Joint Proxy Statement/Prospectus
and of the solicitation of proxies and such costs will be allocated 85% to the
Investors and 15% to the general partners pursuant to the terms of the
Partnership Agreement.  As the Managing General Partner holds approximately
2.69% of the SDIs held by all Investors, 2.69% of the costs borne by the
Investors will be borne by the Managing General Partner, in addition to the
portion of the Partnership's total costs borne by the general partners by
virtue of their interest in the Partnership as general partners.  Solicitations
will be made primarily by mail.  In addition, a number of regular or temporary
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 Investors to encourage the return of proxies, although it does not
anticipate doing so.

                  PARTNERSHIP BUSINESS AND FINANCIAL CONDITION

         The Partnership is a Texas limited partnership formed June 30, 1992.
SDIs in the Partnership are registered under Section 12(g) of the Securities
Exchange Act of 1934.  The Partnership owns Property Interests in producing oil
and gas properties within the continental United States in which the Companion
Partnership also managed by the Managing General Partner owns the non-operating
interests.  By the end of July 1992, the Partnership had expended all of its
original capital contributions for the purchase of Property Interests in oil
and gas producing properties.  During 1997, approximately 85% of the
Partnership's revenue was attributable to natural gas production. The
Partnership has, from time to time, performed workovers and recompletions on
wells in which the Partnership has Property Interests, using funds advanced by
the Managing General Partner to perform these operations, which amounts have
been subsequently repaid.  For information about the business of the
Partnership, see the attached Annual Report on Form 10-K for the year ended
December 31, 1997 and Quarterly Report on Form 10-Q for the quarter ended June
30, 1998.

         Investors made contributions of $8,631,378, in the aggregate to the
Partnership, the net proceeds of which has all been invested.  The Managing
General Partner has made capital contributions with respect to its general
partner interest of $1,018,865.  Additionally, pursuant to the right of
presentment set forth in the Partnership Agreement, it has purchased 232,500
SDIs from Investors.  From inception through July 31, 1998, the Partnership has
made net cash distributions to its Investors totaling $5,799,100.  Details of
the amounts of cash distributions made to partners over the past three years
and nine months are set out under "Cash Distributions" below.  Through July 31,
1998, the Managing General Partner has received net cash distributions from the
Partnership of $1,058,933 with respect to its general partner interest, and
$37,213 related to the number of SDIs it purchased from Investors.  On a per
SDI basis, Investors had received, as of July 31, 1998, $0.67 per $1.00 SDI, or
approximately 67.2% 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.  When the Managing General Partner
projected future oil and gas prices to evaluate the economic viability of an





                                       21
<PAGE>   439
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 $16.82 per
barrel of oil and $1.51 per Mcf of natural gas.  The majority of the
Partnership's Property Interests were acquired by the end of July 1992 and were
comprised principally of natural gas reserves. At that time current prices were
predicted to escalate according to certain parameters from then current levels
to approximately $26.27 per barrel of oil and $2.42 per Mcf of natural gas
during 1997.  The predicted price increases did not occur, and prices fell
precipitously from 1994 to 1995.  Most of the Partnership's reserves were
produced from 1992 to 1996, during which time the oil prices received by the
Partnership for its production in fact averaged $13.71 per barrel, but the
prices for the Partnership's principal asset, natural gas, averaged
approximately $1.89 per Mcf.  A comparison of gas prices as described in this
paragraph appears in the graph presented below.

         The following graphs illustrate the effect on Partnership performance
of the variance between gas prices projected at the time of acquisition of the
Partnership's Property Interests and actual gas prices received for production
(as illustrated in the second graph) during the Partnership's existence.
Information has been presented as to gas prices only due to the fact that a
substantial majority of the Partnership's production has been natural gas.

                                       23
<PAGE>   441
         Lower prices also have 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.

CASH DISTRIBUTIONS

         Cash distributions are made to the partners in the Partnership on a
quarterly basis.  During the past three years and the first nine months of
1998, aggregate cash distributions made to all partners in the Partnership
(including the Managing General Partner) and the cash distributions per SDI
made to the Investors were:

TRANSACTIONS BETWEEN THE MANAGING GENERAL PARTNER AND THE PARTNERSHIP

         Under the Partnership Agreement, the Managing General Partner has
received certain compensation for its services and reimbursement for
expenditures made on behalf of the Partnership, which was paid at closing of
the offering of SDIs, in addition to revenues distributable to the Managing
General Partner with respect to its general partner interest or with respect to
SDIs it has purchased under the Investors' right of presentment.  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 internal acquisition
                 costs reimbursements of $194,915 from the Partnership from
                 inception through December 31, 1997, none of which has been
                 received during the two years ended December 31, 1997.

         o       The Managing General Partner receives operating fees for wells
                 in which the Partnership has Property Interests and for which
                 the Managing General Partner or its affiliates serve as
                 operator.  During the years ended December 31, 1997 and
                 December 31, 1996 the aggregate operating fees paid to the
                 Company as operator by the Partnership were $65,716 and
                 $68,584, respectively.  Monthly operating fees range from $200
                 to $1,100 per well on an 8/8th's basis (i.e., the total amount
                 of operating fees paid by all interest owners in the well).
                 If the Property Interests are sold to the Managing General
                 Partner, there should be no change in its status as operator
                 for a number of the wells in which the Partnership has a
                 Property Interest.  The Managing General Partner believes that
                 it will be positively affected, on the other hand, by
                 liquidation of the Partnership, both on the basis of its





                                       24
<PAGE>   442
                 ownership interest in the Partnership and for other reasons
                 set out under "Special Factors--Managing General Partner
                 Benefits" in this Supplement.

         o       The Managing General Partner is entitled to be reimbursed 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
                 Investors' original capital contributions to the Partnership
                 relative to investor contributions to all public partnerships
                 formed to purchase interests in producing properties for which
                 the Managing General Partner serves in that capacity.  Through
                 December 31, 1997, the Managing General Partner had received
                 $796,069 in the general and administrative overhead allowance
                 from the Partnership, of which $129,471 and $129,471 have been
                 reimbursed during the years ended December 31, 1997 and
                 December 31, 1996, respectively.

         o       The Managing General Partner has been reimbursed $20,541 in
                 direct expenses by the Partnership, all of which was billed
                 by, and then paid directly to, third party vendors, of which
                 $3,155 and $4,159 have been reimbursed during the years ended
                 December 31, 1997 and December 31, 1996, respectively.

         o       The Managing General Partner has received a nonaccountable
                 incentive amount of $213,301 for services rendered from
                 inception through December 31, 1997, of which $14,918 and
                 $21,387 have been reimbursed during the years ended December
                 31, 1997 and December 31, 1996, respectively.

NO TRADING MARKET

         There is no trading market for the SDIs, and none is expected to
develop, as described above under "Special Factors--Fairness of Proposed Sale
of Assets to the Managing General Partner as Compared to Continuing
Operations." Under the Partnership Agreement, Investors have the right to
present their SDIs to the Managing General Partner for repurchase at a price
determined in accordance with the formula established by the Partnership
Agreement.  Originally 585 Investors invested in the Partnership.  As of
__________, 1998, there were 570 Investors (excluding the Managing General
Partner).  The number of SDIs in the Partnership issued and outstanding at that
date was 8,631,378.  Through December 31, 1997, the Managing General Partner
had purchased 232,500 SDIs from Investors pursuant to the right of presentment.
The Managing General Partner does not have an obligation to repurchase Investor
interests pursuant to this right of presentment, but merely an option to do so
when such interests are presented for repurchase.

PRINCIPAL HOLDERS OF INVESTOR SDIS

         The Managing General Partner holds 2.69% of all outstanding SDIs of
the Partnership, resulting from the purchase of SDIs from Investors under their
right of presentment.  To the knowledge of the Managing General Partner, there
is no holder of SDIs that holds more than 5% of the SDIs.

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.

                   SUMMARY OF FEDERAL INCOME TAX CONSEQUENCES

GENERAL

         The following briefly summarizes the federal income tax consequences
set forth under "Federal Income Tax Consequences of Adoption of the Proposals"
in the Joint Proxy Statement/Prospectus.  Statements of legal conclusions
herein regarding tax consequences are based upon an opinion of Hoops & Levy,
L.L.P., Special Tax Counsel, 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 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 Investors.

         A MORE COMPLETE SUMMARY OF THE FEDERAL INCOME TAX CONSEQUENCES TO
INVESTORS MAY BE FOUND IN THE REGISTRATION STATEMENT IN "FEDERAL INCOME TAX
CONSEQUENCES OF ADOPTION OF THE PROPOSALS."  THIS SUMMARY DOES NOT DESCRIBE ALL
THE TAX ASPECTS WHICH MAY AFFECT INVESTORS NOR IS IT A COMPLETE DESCRIPTION OF
THE TAX ASPECTS IT DOES DESCRIBE.  It is generally directed to individual
Investors who are the original purchasers of the SDIs and hold interests in the
Partnership as "capital assets" (generally, property held for investment).
Each Investor that is a corporation, trust, estate, tax exempt entity, or other
partnership 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.

         TAXABLE GAIN OR LOSS UPON SALE OF PROPERTIES

         Investors will realize and recognize gain or loss, or a combination of
both, upon the Partnership's sale of its properties prior to liquidation.  It
is projected, however, that Investors will realize a net taxable loss upon the
sale of Partnership properties.  Notwithstanding the foregoing, Investors are
not expected to realize any gain or loss upon the sale of properties the
Partnership receives from its Companion Partnership and sells to the Managing
General Partners.  Because the oil and gas properties, and related assets,
owned by the Partnership are properties used in a trade or business, the
character of gains and losses realized by the Investors generally will be
governed by Section 1231 of the Code.  Realized gains and losses generally





                                       26
<PAGE>   444
must be recognized and reported in the year the sale occurs. Each Investor's
recognized allocable share of the net Partnership 1231 gains or losses must be
netted with that Investor's individual section 1231 gains and losses recognized
during the year in order to determine the character of such net gains or net
losses under section 1231.  Net gains will be treated as capital gains except
to the extent recharacterized as ordinary income due to recapture and net
losses will be treated as ordinary losses.

         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 an Investor in liquidation is less than such Investor's adjusted
tax basis in his Partnership interest, the Investor will realize and recognize
a capital loss to the extent of the excess.  If the amount of cash distributed
is greater than such Investor's adjusted tax basis in his Partnership interest,
the Investor will recognize a capital gain to the extent of the excess.

         CAPITAL GAIN TAX

         Net long-term capital gains of individuals, trusts and estates
generally will be taxed at a maximum rate of 20%, while ordinary income,
including income from the recapture of intangible drilling and development
costs, depreciation and depletion, will be taxed at a maximum rate depending on
that Investor's taxable income of 36% or 39.6%.


         PASSIVE LOSS LIMITATIONS

         Investors 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.

         An Investor'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.

         THE FOREGOING DISCUSSION IS A SUMMARY OF THE INCOME TAX  CONSEQUENCES
SET FORTH UNDER "FEDERAL INCOME TAX CONSEQUENCES OF ADOPTION OF THE PROPOSALS"
IN THE JOINT PROXY STATEMENT/PROSPECTUS. IT IS NOT INTENDED AS AN ALTERNATIVE
FOR INDIVIDUAL TAX PLANNING.  EACH INVESTOR SHOULD CONSULT HIS, HER OR ITS OWN
TAX ADVISOR CONCERNING THE PARTICULAR FEDERAL, STATE, LOCAL, FOREIGN AND OTHER
TAX CONSEQUENCES APPLICABLE TO HIM, HER OR IT OF THE SALE OF PROPERTIES AND THE
LIQUIDATION OF THE PARTNERSHIP.

Attn: Special Transactions Committee FAIR MARKET VALUE ESTIMATE
      Board of Directors             SWIFT ENERGY OPERATING PARTNERS 1992-B LTD.
      97-003-133


Gentlemen:

At your request, we have audited the proved, probable and possible reserves and
future net cash flow as of December 31, 1998, prepared by Swift Energy Company
("Swift") for certain interests owned by the partners in Swift Energy Operating
Partners 1992-B Ltd. This audit has been conducted according to the Standards
Pertaining to the Estimating and Auditing of Oil and Gas Reserve Information
approved by the Board of Directors of the Society of Petroleum Engineers on
October 30, 1979.  We have reviewed these properties and where we disagreed
with the Swift reserve estimates, Swift revised its estimates to be in
agreement.

From this audit, and in consultation with J.R. Butler and Company, our estimate
of the fair market value of this partnership is $2,257,441.

Fair market value as used herein is defined as that price that a willing buyer
will pay and a willing seller will accept at a given point in time, with
neither the buyer nor the seller under any compulsion to buy or sell, and both
having reasonable knowledge of all the material circumstances.

To estimate the fair market value attributable to the proved developed
producing reserves, the 10 percent discounted future net cash flow was
multiplied by a suitable factor (less than one) to account for the risk
associated with the reserves, operating expenses, and prices and to approximate
tax consequences. The internal rate of return and payout time were computed for
this quantity and compared with those at which current acquisitions are
completed. Suitable adjustments are then made to correspond to these two
financial indices. Proved developed nonproducing, proved undeveloped, probable
and possible reserves require capital investments and must be treated
appropriately. For these cases, the capital is added to the discounted net cash
flow, then multiplied by a suitable risk factor and the capital then
subtracted. This has the effect that capital is spent with certainty and the
operating cash income is burdened with the risk. Internal rate of return and
payout time is calculated for each estimate to establish reasonableness based
upon it the reserve category. The estimated future net cash flow is that cash
flow which will be realized from the sale of the estimated net reserves after
deduction of royalties, ad valorem and production taxes, direct operating

costs and capital expenditures, when applicable.  Surface and well equipment 
salvage values and well plugging and field abandonment costs have not been 
considered in the cash flow projections.  Future net cash flow as stated in 
this report is before the deduction of federal income tax.
        
The following parameters are incorporated in the economic projections
referenced in this report.  Initial oil prices are the existing prices on
December 31, 1997, and are escalated 3.5 percent per year beginning in 1999
through the year 2013 after adjusting for transportation and gravity variances.
Initial natural gas prices are those existing on December 31, 1997, and are
escalated 3.5 percent per year beginning in 1999 through the year 2013 after
adjusting for transportation and Btu content.  Operating expenses are escalated
at an annual rate of 3.5 percent until the year 2013.  The actual prices that
will be received and the associated costs may be more or less than those
projected.

For those wells with sufficient production history, reserve estimates and rate
projections are based on the extrapolation of established performance trends.
Reserves for other producing and nonproducing properties have been estimated
from volumetric calculations and analogy with the performance of comparable
wells.  The reserves referenced in this study are estimates only and should not
be construed as exact quantities.  Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available. The proved reserves are
estimated in accordance with the definitions included in the Securities and
Exchange Commission Regulation S-X, Rule 4-10(a) except for the price and cost
escalations. The definitions are included in part as Attachment I. The probable
and possible reserves conform to the definitions approved by the Society of
Petroleum Engineers, Inc. The definitions are included as Attachment II.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented.  The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December. Interim production to December 31, 1997, has been
estimated.  Operating expenses as supplied by Swift were not audited, but were
reviewed for reasonableness. No independent well tests, property inspections or
audits of operating expenses were conducted by our staff in conjunction with
this study.  We did not verify or determine the extent, character, obligations,
status or liabilities, if any, arising from any current or possible future
environmental liabilities that might be applicable.

In order to audit the reserves, costs and future cash flows referenced in this
report, we have relied in part on geological, engineering and economic data
furnished by our client.  Although we have made a best efforts attempt to
acquire all pertinent data and to analyze it carefully with methods accepted by
the petroleum industry, there is no guarantee that the volumes of oil or gas or
the cash flows projected will be realized.  The reserve and cash flow
projections referenced in this report may require revision as additional data
become available.

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

                         PETROLEUM RESERVES DEFINITIONS
   SOCIETY OF PETROLEUM ENGINEERS (SPE) AND WORLD PETROLEUM CONGRESS (WPC)(1)

Reserves are those quantities of petroleum which are anticipated to be
commercially recovered from known accumulations from a given date forward. All
reserve estimates involve some degree of uncertainty. The uncertainty depends
chiefly on the amount of reliable geologic and engineering data available at the
time of the estimate and the interpretation of these data. The relative degree
of uncertainty may be conveyed by placing reserves into one of two principal
classifications, either proved or unproved. Unproved reserves are less certain
to be recovered than proved reserves and may be further sub-classified as
probable and possible reserves to denote progressively increasing uncertainty in
their recoverability.

The intent of the SPE and WPC in approving additional classifications beyond
proved reserves is to facilitate consistency among professionals using such
terms. In presenting these definitions, neither organization is recommending
public disclosure of reserves classified as unproved. Public disclosure of the
quantities classified as unproved reserves is left to the discretion of the
countries or companies involved.

Estimation of reserves is done under conditions of uncertainty. The method of
estimation is called deterministic if a single best estimate of reserves is made
based on known geological, engineering and economic data. The method of
estimation is called probabilistic when the known geological, engineering, and
economic data are used to generate a range of estimates and their associated
probabilities. Identifying reserves as proved, probable, and possible has been
the most frequent classification method and gives an indication of the
probability of recovery. Because of potential differences in uncertainty,
caution should be exercised when aggregating reserves of different
classifications.

Reserves estimates will generally be revised as additional geologic or
engineering data become available or as economic conditions change. Reserves do
not include quantities of petroleum being held in inventory, and may be reduced
for usage of processing losses if required for financial reporting.

Reserves may be attributed to either natural energy or improved recovery
methods. Improved recovery methods include all methods for supplementing natural
energy or altering natural forces in the reservoir to increase ultimate
recovery. Examples of such methods are pressure maintenance, cycling,
waterflooding, thermal methods, chemical flooding, and the use of miscible and
immiscible displacement fluids. Other improved recovery methods may be developed
in the future as petroleum technology continues to evolve.

PROVED RESERVES

Proved reserves are those quantities of petroleum which, by analysis of
geological and engineering data, can be estimated with reasonable certainty to
be commercially recoverable, from a given date forward, from known reservoirs
and under current economic conditions, operating methods, and government
regulations. Proved reserves can be categorized as developed or undeveloped.

If deterministic methods are used, the term reasonable certainty is intended to
express a high degree of confidence that the quantities will be recovered. If
probabilistic methods are used, there should be at least a 90% probability that
the quantities actually recovered will equal or exceed the estimate.

Establishment of current economic conditions should include relevant historical
petroleum prices and associated costs and may involve an averaging period that
is consistent with the purpose of the reserve estimate, appropriate contract
obligations, corporate procedures, and government regulations involved in
reporting these reserves.

In general, reserves are considered proved if the commercial producibility of
the reservoir is supported by actual production or formation tests. In this
context, the term proved refers to the actual quantities of petroleum reserves
and not just the productivity of the well or reservoir. In certain cases,
proved reserves may be assigned on the basis of well logs and/or core analysis
that indicate the subject reservoir is hydrocarbon bearing and is analogous to
reservoirs in the same area that are producing or have demonstrated the ability
to produce on formation tests.

The area of the reservoir considered as proved includes (1) the area delineated
by drilling and defined by fluid contacts, if any, and (2) the undrilled
portions of the reservoir that can reasonably be judged as commercially
productive on the basis of available geological and engineering data. In the
absence of data on fluid contacts, the lowest known occurrence of hydrocarbons
controls the proved limit unless otherwise indicated by definitive geological,
engineering or performance data.

<PAGE>   454

Reserves may be classified as proved if facilities to process and transport
those reserves to market are operational at the time of the estimate or there is
a reasonable expectation that such facilities will be installed. Reserves in
undeveloped locations may be classified as proved undeveloped provided (1) the
locations are direct offsets to wells that have indicated commercial production
in the objective formation, (2) it is reasonably certain such locations are
within the known proved productive limits of the objective formation, (3) the
locations conform to existing well spacing regulations where applicable, and (4)
it is reasonably certain the locations will be developed. Reserves from other
locations are categorized as proved undeveloped only where interpretations of
geological and engineering data from wells indicate with reasonable certainty
that the objective formation is laterally continuous and contains commercially
recoverable petroleum at locations beyond direct offsets.

Reserve which are to be produced through the application of established improved
recovery methods are included in the proved classification when (1) successful
testing by a pilot project or favorable response of an installed program in the
same or an analogous reservoir with similar rock and fluid properties provides
support for the analysis on which the project was based, and, (2) it is
reasonably certain that project will proceed. Reserves to be recovered by
improved recovery methods that have yet to be established through commercially
successful applications are included in the proved classification only (1) after
a favorable production response from the subject reservoir from either (a) a
representative pilot or (b) an installed program where the response provides
support for the analysis on which the project is based and (2) it is reasonably
certain the project will proceed.

UNPROVED RESERVES

Unproved reserves are based on geologic and/or engineering data similar to that
used in estimates of proved reserves; but technical, contractual, economic, or
regulatory uncertainties preclude such reserves being classified as proved.
Unproved reserves may be further classified as probable reserves and possible
reserves.

Unproved reserves may be estimated assuming future economic conditions different
from those prevailing at the time of the estimate. The effect of possible future
improvements in economic conditions and technological developments can be
expressed by allocating appropriate quantities of reserves to the probable and
possible classifications.

PROBABLE RESERVES

Probable reserves are those unproved reserves which analysis of geological and
engineering data suggests are more likely than not to be recoverable. In this
context, when probabilistic methods are used, there should be a least a 50%
probability that the quantities actually recovered will equal or exceed the sum
of estimated proved plus probable reserves.

In general, probable reserves may include (1) reserves anticipated to be proved
by normal step-out drilling where subsurface control is inadequate to classify
these reserves as proved, (2) reserves in formations that appear to be
productive based on well log characteristics but lack core data or definitive
tests and which are not analogous to producing or proved reservoirs in the area,
(3) incremental reserves attributable to infill drilling that could have been
classified as proved if closer statutory spacing had been approved at the time
of the estimate, (4) reserves attributable to improved recovery methods that
have been established by repeated commercially successful applications when (a)
a project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir characteristics appear favorable for commercial application, (5)
reserves in an area of the formation that appears to be separated from the
proved area by faulting and the geologic interpretation indicates the subject
area is structurally higher than the proved area, (6) reserves attributable to a
future workover, treatment, re-treatment, change of equipment, or other
mechanical procedures, where such procedure has not been proved successful in
wells which exhibit similar behavior in analogous reservoirs, and (7) 
incremental reserves in proved reservoirs where an alternative interpretation of
performance or volumetric data indicates more reserves than can be classified as
proved.

POSSIBLE RESERVES

Possible reserves are those unproved reserves which analysis of geological and
engineering data suggests are less likely to be recoverable than probable
reserves. In this context, when probabilistic methods are used, there should be
a least a 10% probability that the quantities actually recovered will equal or
exceed the sum of estimated proved plus probable plus possible reserves.

In general, possible reserves may include (1) reserves which, based on
geological interpretations, could possibly exist beyond areas classified as
probable, (2) reserves in formations that appear to be petroleum bearing based
on log and core analysis but may not be productive at commercial rates, (3)
incremental reserves attributed to infill drilling that are subject to technical
uncertainty, (4) reserves attributed to improved recovery methods when (a) a
project or pilot is planned but not in operation and (b) rock, fluid, and
reservoir

<PAGE>   455

characteristics are such that a reasonable doubt exists that the project will be
commercial, and (5) reserves in an area of the formation that appears to be
separated from the proved area by faulting and geological interpretation
indicates the subject area is structurally lower than the proved area.

RESERVE STATUS CATEGORIES

Reserve status categories define the development and producing status of wells
and reservoirs.

     DEVELOPED: Developed reserves are expected to be recovered from existing
     wells including reserves behind pipe. Improved recovery reserves are
     considered developed only after the necessary equipment has been installed,
     or when the costs to do so are relatively minor. Developed reserves may be
     sub-categorized as producing or non-producing.

         PRODUCING: Reserves subcategorized as producing are expected to be
         recovered from completion intervals which are open and producing at the
         time of the estimate. Improved recovery reserves are considered
         producing only after the improved recovery project is in operation.

         NON-PRODUCING. Reserves subcategorized as non-producing include shut-in
         and behind-pipe reserves. Shut-in reserves are expected to be recovered
         from (1) completion intervals which are open at the time of the
         estimate but which have not started producing, (2) wells which were
         shut-in for market conditions or pipeline connections (3) wells not
         capable of production for mechanical reasons. Behind-pipe reserves are
         expected to be recovered from zones in existing wells, which will
         require additional completion work or future recompletion prior to the
         start of production.

     UNDEVELOPED RESERVES: Undeveloped reserves are expected to be recovered:
     (1) from new wells on undrilled acreage, (2) from deepening existing wells
     to a different reservoir, or (3) where a relatively large expenditure is
     required to (a) recomplete an existing well or (b) install production or
     transportation facilities for primary or improved recovery projects.

                                            RE:  FAIR MARKET VALUE OPINION
                                                 AS OF DECEMBER 31, 1997

ATTENTION:  SPECIAL TRANSACTIONS COMMITTEE
            SWIFT ENERGY COMPANY BOARD OF DIRECTORS

At the request of SWIFT ENERGY COMPANY (SWIFT), J. R. BUTLER AND COMPANY
(JRBCo) has conducted an evaluation audit of the hydrocarbon reserves and
future net cash flow as of December 31, 1997, associated with 44 Acquisition
Programs located in the U.S.A.  From this audit, and in consultation with H. J.
Gruy and Associates, Inc. (Gruy), JRBCo has generated its opinion of a "fair
market value" for these properties.  The market values of the properties were
distributed to various partnerships based on ownership to determine the fair
market value of each partnership.  In JRBCo's opinion, utilizing the
distribution of properties into the proper partnerships, the estimated market
value of Swift Energy Operating Partners 1992-B, Ltd. is $2,257,441.

Proved reserves in this instance are defined as those estimated volumes of
crude oil, condensate, natural gas, and natural gas liquids that geological and
engineering data demonstrate with reasonable certainty to be commercially
recoverable in the future from known reservoirs under a reasonable price and
cost escalation scenario.  Probable reserves are the estimated quantities of
commercially recoverable hydrocarbons associated with known accumulations which
are based on engineering and geological data similar to those used in the
estimates of proved reserves but, for various reasons, these data lack the
certainty required to classify the reserves as proved.  Possible reserves are
the estimated quantities of commercially recoverable hydrocarbons associated
with known accumulations, which are based on engineering and geological data
which are less complete and less conclusive than the data used in estimates of
probable reserves.  In some cases, economic or regulatory uncertainties may
dictate a probable or possible classification.
<PAGE>   457
Recovery of proved reserves is not without risk but, as generally considered in
the industry, the risk of recovering probable reserves is substantially greater
than that associated with proved categories.  Likewise, possible reserves are
less certain to be recovered than probable.

The reserves and future performance estimates were prepared utilizing standard
petroleum engineering methods.  For properties with sufficient production
history, reserves estimates and rate projections were based primarily on
extrapolation of established performance trends and reconciled, whenever
possible, with volumetric and/or material balance calculations.  For the
non-producing zones and undeveloped locations, reserves were determined by a
combination of volumetric calculations and analogy.  Volumetrically determined
reserves or those determined by analogy are generally subject to greater
qualifications than reserves estimates supported by established production
decline curves and/or material balance calculations.  Determination and
classification of proved reserves were performed (with exception of the use of
escalated prices and costs) in accordance with Securities and Exchange
Commission guidelines.  The definitions used also conform to those promulgated
by the_Society of Petroleum Engineers (SPE) and the World Petroleum Congresses
(WPC).

The reserves and resulting "value estimates" included  in this study are not
exact quantities.  Future conditions may affect the recovery of estimated
reserves, revenue and net cash flow, and all categories of reserves may be
subject to revision and/or reclassification as more performance and well data
become available.  Please note, the reserves estimates made by JRBCo were done
in conjuction with an evaluation audit and are not the result of in-depth field
studies.  In conducting this audit JRBCo reviewed approximately 65% of SWIFT's
proved "PV10  value" (SEC PV10 as of December 31, 1997) for the total 44
Acquisition Programs.

Basic evaluation data were obtained principally from SWIFT and public sources.
The production data available to JRBCo were generally through  August 1997.
Gas and liquid prices were year end (CY 1997) prices as used in SWIFT's
December 31, 1997, SEC cash flow runs.

Estimates of drilling, completion and workover costs were based on information
supplied by SWIFT.  Operating costs were also based on data supplied by SWIFT
in their Lease Operating Statement which was reviewed by JRBCo.  Surface and
well equipment salvage values and well plugging and field abandonment costs
were not considered in the revenue projections.

The estimates of future net cash flow used in market value calculations are
those revenues which should be realized from the sale of the estimated reserves
after deduction of royalties, ad valorem and production taxes, direct operating
costs and required capital expenditures, when applicable.  Future net cash flow
as used in this evaluation is before the deduction of federal income tax.





                                       2
<PAGE>   458
Market value estimates were obtained by applying qualitative risk adjustments
considered appropriate for the various reserves categories and "profit factors"
(as applicable) against discounted future net cash flow values obtained from an
escalated cost and pricing scenario.  Prices, costs and investments were
escalated at 3.5%/year for 15 years.  Final market value estimates were derived
in conjunction and consultation with Gruy.

In the conduct of our review, we have not independently verified the accuracy
and completeness of information and data furnished by SWIFT with respect to
ownership interests, oil and gas production volumes and rates, historical costs
of operation and development, product prices, agreements relating to current
and future operations and sales of production and other information relative to
such things as timing or scheduling of drilling or recompletion operations.

Field inspections were not made in connection with the preparation of this
report.  Furthermore, no judgments were made relative to environmental or other
legal liabilities.

It should be recognized that any oil or gas reserves estimate or forecast of
production and income is a function of engineering and geological
interpretation and judgment.  Such estimates should, therefore, be accepted and
used with the understanding that technical data, economic criteria or
regulatory information obtained subsequent to a study may justify revisions
which could increase or decrease the original estimates of reserves and value.

Neither JRBCo, nor any of its personnel, have any direct or indirect interest
in SWIFT or its affiliates.  JRBCo is an independent consulting firm as
provided in the Standards Pertaining to the Estimating and Auditing of Oil and
Gas Reserves Information promulgated by the Society of Petroleum Engineers.
JRBCo's compensation is not contingent upon the results of its reserves
estimates, cash flow analyses or "market value opinion" which result from its
review of the subject properties.

Swift Energy Company
16825 Northchase Drive, Suite 400
Houston, TX  77060

Attention:  Special Transactions Committee
            Swift Energy Company Board of Directors

Gentlemen:

Pursuant to that certain letter agreement dated February 27, 1998 (the
"Agreement") between the Special Transactions Committee (the "Committee") of
the Board of Directors of Swift Energy Company ("Swift" or the "Company") and
CIBC Oppenheimer Corp. ("CIBC Oppenheimer"), you have retained CIBC Oppenheimer
to prepare an independent financial analysis as to the estimated fair market
value (the "CIBC Oppenheimer Valuation") of various interests (the "Assets") in
oil and gas properties (the "Properties'), which Assets are owned by Swift
Energy Operating Partners 1992-B, Ltd. (the "Partnership") of which the Company
is the managing general partner ("General Partner"). CIBC Oppenheimer performed
a similar analysis for 62 other partnerships (the "Partnerships") of which the
Company is the General Partner. It is CIBC Oppenheimer's understanding that the
General Partner has proposed to purchase substantially all of the Partnership's
Assets and, in turn, dissolve and wind up the Partnership. It is also CIBC
Oppenheimer's understanding that the Committee has also retained the reserve
engineering firms of H.J. Gruy & Associates, Inc. and J.R. Butler & Company
(collectively, the "Engineering Consultants") to prepare a separate analysis as
to the estimated fair market value of the Assets (the "Engineering Consultants'
Valuation").

In arriving at the CIBC Oppenheimer Valuation, we, among other things:

         (i)     Reviewed the historical financial returns to the limited
                 partners of the Partnership;

         (ii)    Held discussions with senior management of the Company as to
                 the Partnership's operational and financial prospects;

         (iii)   Held discussions with senior management of the Company
                 regarding the general characteristics of the Properties
                 underlying the Assets, including location, productive
                 geological formations, future development potential and oil
                 and gas marketing arrangements;

         (iv)    Held discussions with the Engineering Consultants regarding
                 the general characteristics of the Properties underlying the
                 Assets, including location, productive geological formations
                 and future development potential;

         (v)     Reviewed the reserve engineering reports supplied to us by the
                 Engineering Consultants and, particularly, reviewed the
                 estimated future net cash flow to be generated from the
                 production of proved reserves of the Properties underlying the
                 Assets discounted to present value using an annual discount
                 rate of 10% (the "PV-10 Value") dated as of December 31, 1997;
                 these amounts were 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 future
                 income tax expense or depreciation, depletion and
                 amortization;

         (vi)    Reviewed the Engineering Consultants' Valuation of the
                 Properties underlying the Assets;

         (vii)   Reviewed historical operating and financial results of the
                 Properties underlying the Assets which included PV-10 Value,
                 proved reserves on a barrel of oil equivalent ("BOE") basis
                 and projected earnings before interest, taxes and

         (x)     Reviewed and analyzed transactions involving the sale of oil
                 and gas properties we deemed comparable to the Properties
                 underlying the Assets;

         (xi)    Reviewed financial and market data for certain public
                 companies we deemed comparable to the Partnership(s)
                 individually and collectively and to the Company; and

         (xii)   Performed such other analyses and reviewed such other
                 information as we deemed appropriate.

In determining the CIBC Oppenheimer Valuation, we have relied upon and assumed,
without independent verification or investigation and at the direction of the
Committee, (i) the accuracy and completeness of all of the financial and other
information available to us from public sources or provided to us by the
Company and their representatives (including the Engineering Consultants), (ii)
that the reserve engineering reports supplied to us by the Engineering
Consultants as described in clause (v) above have been reasonably prepared and
are based on their best business judgment, (iii) that the information with
respect to the Partnership's ownership of the Assets, as provided to the
Engineering Consultants and to us was accurate in all respects, (iv) with
respect to the historical operating and financial results and projections
provided to us as described in clause and (vii) above, that such information
and projections were reasonably prepared and were based on the best currently
available information, estimates and good faith judgment of the Company's
management and their representatives (including the Engineering Consultants).

Not being experts in the geological evaluation of oil and gas reserves, we
have, with your consent, relied without independent verification upon the audit
of the reserve estimates prepared by the Engineering Consultants for the
purpose of estimating fair market value of the Assets. In addition, we have not
made a physical inspection of the Properties underlying the Assets, nor have we
made any independent evaluations, appraisals or inspections of the Company's or
the Partnership's other assets or the Company's or the Partnership's
liabilities (contingent or otherwise). We have not reviewed any relevant
agreements which may exist between the General Partner and the limited partners
governing the Partnership, nor have we considered the effect which the
ownership structure of the Partnership and the terms of the agreements of the
Partnership may have upon the fairness of the consideration offered by any
general partner of the Partnership. We have not reviewed the books and records
of the Partnership and have assumed, with

your consent, that the Partnership's ownership interests in the Properties
underlying the Assets, as provided to us by you, is true and correct.

The CIBC Oppenheimer Valuation is based upon analyses of the foregoing factors
in light of our assessment of general economic, financial, market and other
conditions and circumstances as of the date of this letter and any changes in
such conditions and circumstances may affect the validity or fairness of the
CIBC Oppenheimer Valuation. CIBC Oppenheimer disclaims any obligations to
update, revise or reaffirm the CIBC Oppenheimer Valuation. The CIBC Oppenheimer
Valuation reflects our estimate of the consideration that could have been
received by the Partnership in a sale of the Assets in an orderly manner in a
private market transaction in which neither buyer nor seller  under any
compunction to complete such transaction.  The CIBC Oppenheimer Valuation falls
within a range of values which we believe, subject to the foregoing conditions,
represent possible fair market value estimates of the Partnership's interest in
the Assets.  The CIBC Oppenheimer Valuation should not be viewed as a guarantee
of the price that a willing buyer might have paid for the Assets.

CIBC Oppenheimer, as part of its investment banking services, is regularly
engaged in the valuation of businesses and securities in connection with
mergers, acquisitions, underwritings, sales and distributions of listed and
unlisted securities and private placements.  CIBC Oppenheimer has provided
certain investment banking and financial advisory services to the Company from
time to time, including acting as co-manager of the Company's Convertible
Subordinated Notes financing in November 1996 and lead manager of the public
offering of the Company's Common Stock in July 1995, and may be involved in
future investment banking activities on behalf of the Company. CIBC Oppenheimer
will also receive a fee upon delivery of this CIBC Oppenheimer Valuation. In
the ordinary course of business, CIBC Oppenheimer actively trades in the equity
securities of the Company for CIBC Oppenheimer's own account and for the
accounts of CIBC Oppenheimer's customers and, accordingly, may at any time hold
a long or short position in such securities.

Based upon and subject to the foregoing, and based upon such other matters as
we consider relevant, it is CIBC Oppenheimer's estimate that the value of Swift
Energy Operating Partners 1992-B, Ltd. interest in the Assets as of the date
hereof is $2,118,171.

This letter is being provided for the use of the Committee in its evaluation of
a possible proposal that the Partnership sell the Assets to the Managing
General Partner and dissolve and wind up its affairs. This letter  is not
intended to confer rights or remedies

upon any stockholder of the Company or any partner of the Partnership and may
not be relied upon by any person or entity other than the Committee. Neither
this letter nor the CIBC Oppenheimer Valuation may be published or otherwise
used or referred to, in whole or part, nor shall any public reference to CIBC
Oppenheimer, this letter or the CIBC Oppenheimer Valuation be made without the
prior written consent of CIBC Oppenheimer; provided, however, that the Company
and the Partnership may include a copy of this letter and a reference to CIBC
Oppenheimer in the proxy statement to be distributed to limited partners of the
Partnership in connection with the solicitation of the approval of the proposal
that the Partnership sell the Assets to the General Partner and dissolve and
wind up its affairs. Neither this letter nor the CIBC Oppenheimer Valuation
constitutes a recommendation to any partner of the Partnership as to how such
partner should vote on or respond to the proposal that the Partnership sell the
Assets to the General Partner and dissolve and wind up its affairs.

Sincerely yours,

CIBC Oppenheimer Corp.

Swift Energy Company
16825 Northchase Drive, Suite 400
Houston, Texas 77060

                                          SWIFT ENERGY OPERATING PARTNERS 1992-B
                                          97-003-133

Gentlemen:

At your request, we have made an audit of the reserves and future net cash flow
as of December 31, 1997, prepared by Swift Energy Company ("Swift") for certain
interests in Swift Energy Operating Partners 1992-B.  This audit has been
conducted according to the standards pertaining to the estimating and auditing
of oil and gas reserve information approved by the Board of Directors of the
Society of Petroleum Engineers on October 30, 1979.  We have reviewed these
properties and where we disagreed with the Swift reserve estimates, Swift
revised its estimates to be in agreement.  The estimated net reserves, future
net cash flow and discounted future net cash flow are summarized by reserve
category in Table 1 for both the 100% Fund Level Partnership and the Limited
Partnership Interest.

The discounted future net cash flow is not represented to be the fair market
value of these reserves and the estimated reserves included in this report have
not been adjusted for risk.

The estimated future net cash flow shown is that cash flow which will be
realized from the sale of the estimated net reserves after deduction of
royalties, ad valorem and production taxes, direct operating costs and required
capital expenditures, when applicable.  Surface and well equipment salvage
values and well plugging and field abandonment costs have not been considered
in the cash flow projections.  Future net cash flow as stated in this report is
before the deduction of state and federal income tax.

In the economic projections, prices, operating costs and development costs
remain constant for the projected life of each lease.

The reserves included in this study are estimates only and should not be
construed as exact quantities.  Future conditions may affect recovery of
estimated reserves and cash flow, and all categories of reserves may be subject
to revision as more performance data become available.  Proved reserves are
estimated in accordance with the definitions contained in Securities and
Exchange Commission Regulation S-X, Rule 4-10 (a).  The definitions are
included in part as Attachment I.

Extent and character of ownership, oil and gas prices, production data, direct
operating costs, capital expenditure estimates and other data provided by Swift
have been accepted as represented.  The production data available to us were
through the month of October 1997, except in those instances in which data were
available through December.  Interim production to December 31, 1997, has been
estimated.  No independent well tests, property inspections or audits of
operating expenses were conducted by our staff in conjunction with this study.
We did not verify or determine the extent, character, obligations, status or
liabilities, if any, arising from any current or possible future environmental
liabilities that might be applicable.

Swift Energy Company                 -2 -                      February 10, 1998

In order to audit the reserves, costs and future net cash flows shown in this
report, we have relied in part on geological, engineering and economic data
furnished by our client.  Although we have made a best efforts attempt to
acquire all pertinent data and to analyze it carefully with methods accepted by
the petroleum industry, there is no guarantee that the volumes of oil or gas or
the cash flows projected will be realized.

Production rates may be subject to regulation and contract provisions, and may
fluctuate according to market demand or other factors beyond the control of the
operator.  The reserve and cash flow projections presented in this report may
require revision as additional data become available.

We are unrelated to Swift and we have no interest in the properties included in
the information reviewed by us.  In particular:

         1.    We do not own a financial interest in Swift or its oil and gas
               properties.

         2.    Our fee is not contingent on the outcome of our work or report.

         3.    We have not performed other services for or have any other
               relationship with Swift that would affect our independence.

If investments or business decisions are to be made in reliance on these
estimates by anyone other than our client, such person with the approval of our
client is invited to visit our offices at his expense so that he can evaluate
the assumptions made and the completeness and extent of the data available on
which our estimates are based.

Any distribution or publication of this report or any part thereof must include
this letter in its entirety.

                                        Yours very truly,

                  DEFINITIONS OF PROVED OIL AND GAS RESERVES(1)


PROVED OIL AND GAS RESERVES

Proved oil and gas reserves are the estimated quantities of crude oil, natural
gas, and natural gas liquid which geological and engineering data demonstrate
with reasonable certainty to be recoverable in future years from known
reservoirs under existing economic and operating conditions, i.e., prices and
costs as of the date the estimate is made. Prices include consideration of
changes in existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

Reservoirs are considered proved if economic producibility is supported by
either actual production or conclusive formation test. The area of a reservoir
considered proved includes (A) that portion delineated by drilling and defined
by gas-oil and/or oil-water contacts, if any, and (B) the immediately adjoining
portions not yet drilled, but which can be reasonably judged as economically
productive on the basis of available geological and engineering data. In the
absence of information on fluid contacts, the lowest known structural occurrence
of hydrocarbons controls the lower proved limit of the reservoir.

Reserves which can be produced economically through application of improved
recovery techniques (such as fluid injection) are included in the "proved"
classification when successful testing by a pilot project, or the operation of
an installed program in the reservoir, provides support for the engineering
analysis on which the project or program was based.

Estimates of proved reserves do not include the following: (A) oil that may
become available from known reservoirs but is classified separately as
"indicated additional reserves"; (B) crude oil, natural gas, and natural gas
liquids, the recovery of which is subject to reasonable doubt because of
uncertainty as to geology, reservoir characteristics, or economic factors; (C)
crude oil, natural gas, and natural gas liquids, that may occur in undrilled
prospects; and (D) crude oil, natural gas, and natural gas liquids, that may be
recovered from oil shales, coal, gilsonite and other such sources.


PROVED DEVELOPED OIL AND GAS RESERVES

Proved developed oil and gas reserves are reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery should be included as "proved
developed reserves" only after testing by a pilot project or after the operation
of an installed program has confirmed through production response that increased
recovery will be achieved.


PROVED UNDEVELOPED RESERVES

Proved undeveloped oil and gas reserves are reserves that are expected to be
recovered from new wells on undrilled acreage, or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling units offsetting productive units
that are reasonably certain of production when drilled. Proved reserves for
other undrilled units can be claimed only where it can be demonstrated with
certainty that there is continuity of production from the existing productive
formation. Under no circumstances should estimates for proved undeveloped
reserves be attributable to any acreage for which an application of fluid
injection or other improved recovery technique is contemplated, unless such
techniques have been proved effective by actual tests in the area and in the
same reservoir.

ITEM 20.         INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Article 2.02-1 of the Texas Business Corporation Act provides that a
corporation may indemnify its officers, directors, employees and agents for
expenses and costs incurred in certain proceedings arising out of actions taken
in their official capacity only if such persons were acting in good faith and
in a manner reasonably believed to be in or not opposed to the best interests
of the corporation, except in relation to matters in which they have been found
liable (i) to the corporation, or (ii) on the basis that personal benefit was
improperly received regardless of whether or not the benefit resulted from
action taken in their official capacity.  In the case of any criminal
proceeding, such persons must also have had no reasonable cause to believe such
conduct was unlawful.  Article 2.02-1 further provides that a corporation shall
indemnify its officers and directors against reasonable expenses incurred in
connection with proceedings arising out of actions taken in their official
capacity in which such persons have been wholly successful, on the merits or
otherwise, in the defense of such actions.  The bylaws of the Company, as
amended, provide for indemnification in favor of the Company's directors,
officers, and employees to the fullest extent permitted by Article 2.02-1.
Additionally, the Company amended its Articles of Incorporation, with
shareholder approval, to confirm that the Company has the power to indemnify
certain persons in such circumstances as are provided in its bylaws.  The
amendment further enables the Company to enter into additional insurance and
indemnity arrangements at the discretion of the Board of Directors.  The
Company has entered into Indemnification Agreements with each of its officers
and directors, the form of which was approved by the shareholders of the
Company, that essentially indemnify such individuals to the fullest extent
permitted by law.

         Article 7.06 of the Texas Miscellaneous Corporation Laws Act provides
that a corporation's articles of incorporation may provide for the elimination
or limitation of a director's liability.  The Company's Articles of
Incorporation to eliminate the liability of directors to the corporation or its
shareholders for monetary damages for an act or omission in his capacity as a
director, with certain specified exceptions to the Company and its shareholders
to the fullest extent permitted by Article 7.06 of the Texas Miscellaneous
Corporation Laws Act.

         The Company maintains insurance, the general effect of which is to
provide coverage for the Company with respect to amounts that it is required to
pay officers and directors under the indemnity provisions described above and
coverage for officers and directors against certain liabilities, including
certain liabilities under the federal securities law.

    ITEM 22.     UNDERTAKINGS.


   
    A.           The undersigned registrant hereby undertakes:

                 (1)      To file, during any period in which offers or sales
                 are being made, a post-effective amendment to this
                 registration statement:

                          (i)     To include any prospectus required by 
                          section 10(a)(3) of the Securities Act of 1933;

                          (ii)    To reflect in the prospectus any facts or
                          events arising after the effective date of the
                          registration statement (or the most recent
                          post-effective amendment thereof) which, individually
                          or in the aggregate, represent a fundamental change
                          in the information set forth in the registration
                          statement.  Notwithstanding the foregoing, any
                          increase or decrease in volume of securities offered
                          (if the total dollar value of securities offered
                          would not exceed that which was registered) and any
                          deviation from the low or high end of the estimated
                          maximum offering range may be reflected in the form
                          of prospectus filed with the Commission pursuant to
                          Rule 424(b) (Section  230.424(b) of this chapter) if,
                          in the aggregate, the changes in volume and price
                          represent no more than 20% change in the maximum
                          aggregate offering price set forth in the
                          "Calculation of Registration Fee" table in the
                          effective registration statement.

                          (iii)   To include any material information with
                          respect to the plan of distribution not previously
                          disclosed in the registration statement or any
                          material change to such information in the
                          registration statement.

                 (2)      That, for the purpose of determining any liability
                 under the Securities Act of 1933, each such post-effective
                 amendment shall be deemed to be a new registration statement
                 relating to the securities offered therein, and the offering
                 of such securities at that time shall be deemed to be the
                 initial bona fide offering thereof.

                 (3)      To remove from registration by means of a
                 post-effective amendment any of the securities being
                 registered which remain unsold at the termination of the
                 offering.
    

    B.           The undersigned registrant hereby undertakes that, for
                 purposes of determining any liability under the 1933 Act, each
                 filing of the registrant's annual report pursuant to Section
                 13(a) or Section 15(d) of the Securities Exchange Act of 1934
                 (the "1934 Act") (and, where applicable, each filing of an
                 employee benefit plan's annual report pursuant to Section
                 15(d) of the 1934 Act) that is incorporated by reference in
                 the Registration Statement shall be deemed to be a new
                 registration statement relating to the securities offered
                 therein, and the offering of such securities at that time
                 shall be deemed to be the initial bona fide offering thereof.

    C.           The undersigned registrant hereby undertakes to deliver or
                 cause to be delivered with the prospectus, to each person to
                 whom the prospectus is sent or given, the latest annual report
                 to security holders that is incorporated by reference in the
                 prospectus and furnished pursuant to and meeting the
                 requirements of Rule 14a-3 or Rule 14c-3 under the Securities
                 Exchange Act of 1934; and, where interim financial information
                 required to be presented by Article 3 of Regulation S-X are
                 not set forth in the prospectus, to deliver, or cause to be
                 delivered to each person to whom the prospectus is sent or
                 given, the latest quarterly report that is specifically
                 incorporated by reference in the prospectus to provide such
                 interim financial information.

Each Limited Partnership on Exhibit A
Swift Energy Company
Managing General Partner
16825 Northchase Drive, Suite 400
Houston, Texas 77060

                  Re:  Form S-4 Swift Energy Company, Registrant -- Tax Aspects

Gentlemen:

         We have acted as special tax counsel to the limited partnerships listed
on Exhibit A attached hereto (collectively the "Partnerships"), each of which
was formed under the Texas Revised Limited Partnership Act, in connection with
an offering of limited partnership interests pursuant to registered offerings
made by Swift Energy Company over a period of nine years. We also have acted as
special tax counsel to Swift Energy Company, a Texas corporation that acts as
Managing General Partner of each of the Partnerships in connection with the
"Federal Income Tax Consequences of Adoption of the Proposals" and "Material
Federal Income Tax Consideration of Electing to Receive Common Stock in Lieu of
Cash Upon Partnership Liquidation" of the Final Amendment to Form S-4
Registration Statement, dated ________ (the "Registration Statement") and the
Summary of Federal Income Tax Consequences in each Supplement to the
Registration Statement. You have requested our opinion regarding the federal
income tax consequences of (i) the sale of all of each Partnership's oil and gas
assets and the liquidation of each Partnership approving said sale and (ii) an
Investor's purchase of Swift Energy Company stock with Partnership property
sales proceeds, each in accordance with the terms of the Registration Statement,
the Supplement for each Partnership and each Partnership's Limited Partnership
Agreement.

         The facts, as we understand them, are as set forth in the Registration
Statement, each Supplement thereto and all exhibits to each. As to various
questions of fact material to the opinions expressed below, we have relied in
part to the extent we deemed reasonably appropriate upon the disclosures made by
Swift Energy Company in the Registration Statement and all attachments thereto
including without limitation the Supplements, other representations made by
officers and employees of Swift Energy Company to us, and other documents,
records and instruments furnished to us by Swift Energy Company, without
independent verification of the accuracy of such representations, documents,
records or instruments. With regard to documents we have received or reviewed,
we have assumed the conformity of all copies to original documents and we also
have assumed the genuineness of signatures and the authenticity and accuracy of
all original documents or copies thereof. We also have assumed that the
Partnerships constitute partnerships for federal income tax purposes and have
relied upon certain private letter rulings received by the Managing General
Partner on behalf of the Partnerships.

   
         Except to the extent affected by the individual circumstances of
Investors, as defined in the Registration Statement, and local law, the
disclosures contained under the "Federal Income Tax Consequences of Adoption of
the Proposals" and "Material Federal Income Tax Consideration of Electing to
Receive Common Stock in Lieu of Cash Upon Partnership Liquidation" in the
Registration Statement set forth our opinion of the federal income tax
considerations material to those individuals considering either the sale of
Partnership Properties pursuant to the Proposals or a purchase of Company stock,
or both. Additionally, the summary descriptions contained in the Supplements to
the Registration Statement under the heading "Summary of Federal Income Tax
Consequences" are reasonable summaries of the section of the Registration
Statement entitled "Federal Income Tax Consequences of Adoption of the
Proposals."
    

         Our opinion as to the federal income tax consequences as stated under
"Federal Income Tax Consequences of Adoption of the Proposals" and "Material
Federal Income Tax Consideration of Electing to Receive Common Stock in Lieu of
Cash Upon Partnership Liquidation" is merely a statement as to what we regard
the federal income tax consequences to be. It is based upon our interpretations
of statutes, regulations, notices, published rulings, representations of the
Managing General Partner, certain specifically applicable private letter
rulings, and other legal precedents in effect as of the date hereof.

         The Internal Revenue Service Restructuring and Reform Act of 1998 was
enacted on July 22, 1998. This act materially modifies the treatment and rights
of many taxpayers relative to the Internal Revenue Service and generally reduces
the long term capital gains holding period on most assets for individuals to
more than twelve months for sales made after December 31, 1997. The Taxpayer
Relief Act of 1997, enacted on August 5, 1997, significantly revised the
Internal Revenue Code of 1986 and may materially affect individual taxpayers.
There have been numerous other, recent changes in the taxing statutes, including
the Small Business Job Protection Act of 1996, other 1996 acts that made changes
to the tax laws, the Omnibus Budget Reconciliation Act of 1993, the Revenue
Reconciliation Act of 1990, and Comprehensive Energy Policy Act of 1992. The
taxing statutes also have been amended by other public laws pertaining to
non-tax matters. Certain provisions of each act, as well as previous acts,
remain unclear due to the limited amount of relevant legislative history and the
lack of proposed or final regulations interpreting the provisions of such acts
and previous acts.

         It is reasonable to expect further changes in the federal income tax.
The authority upon which we rely as to any particular federal income tax
consequences is subject to change at any time and such change may have
retroactive effect.

         We consent to the use of this opinion and the reference to our firm in
the Registration Statement.

                                            Very truly yours,




                                            HOOPS & LEVY, L.L.P.
