Dear Limited Partner:

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

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

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

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

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


                                            SWIFT ENERGY COMPANY,

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

                                     SUMMARY

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

      Under Article XVI.C of the Partnership Agreement,  the affirmative vote of
Limited Partners holding at least 51% of the Units then held by Limited Partners
as of the Record Date (as  defined) is required  for  approval of the  Proposal.
Each Limited Partner appearing on the Partnership's records as of June ___, 1997
(the "Record Date"), is entitled to notice of the Meeting and is entitled to one
vote for each Unit  held by such  Limited  Partner.  Under  Article  XX.H of the
Partnership  Agreement,  the Managing General Partner may not vote its Units for
matters  such as the  Proposal.  The Managing  General  Partner  currently  owns
approximately 6.26% of all outstanding Units. Therefore, the affirmative vote of
holders of 51% of the remaining Units is required to approve the proposed sale.

      The Partnership's assets consist of working interests in producing oil and
gas properties (the "Property  Interests").  The Property Interests are burdened
by a single net profits interest in the producing oil and gas properties granted
to  an  affiliated  companion  partnership  (the  "Pension  Partnership").  Upon
approval of the Proposal by the Limited  Partners,  the Managing General Partner
intends  to sell  substantially  all of the  Partnership's  Property  Interests,
together  with  the  Pension  Partnership's  net  profits  interest  in the same
properties, in a sale or series of sales, use the proceeds to pay or provide for
the payment of liabilities, and then wind up the affairs of the Partnership. The
Partnership's  Property  Interests cover 358 wells.  The total PV10 value of the
Partnership's  remaining  reserves as of December 31, 1996 was  $1,187,752.  The
most  significant  property  owned by the  Partnership  is the  Velrex  Field in
Schleicher  County,  Texas, which accounts for approximately 33% of the value of
the  Partnership's  remaining  reserves.  During 1996,  approximately 86% of the
Partnership's  revenue  was  attributable  to natural gas  production.  For more
information,  see the  attached  Annual  Report on Form 10-K for the year  ended
December 31, 1996 and the Form 10-Q for the first quarter of 1997.

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

       It is possible,  though unlikely, that less than all of the Partnership's
Property  Interests  will be sold.  See "The  Proposal--Steps  to Implement  the
Proposal--Negotiated  Sale." The Managing  General Partner  anticipates that the
majority  of  sales  will be made by the end of 1997.  The  sale of  Partnership
Property  Interests  that  account  for at least 66% of the  total  value of the
Partnership   Property   Interests  will  cause  the   Partnership  to  dissolve
automatically under the terms of the Partnership Agreement and the Texas Act.

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

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

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

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

                               GENERAL INFORMATION

DOCUMENTS INCLUDED

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

VOTE REQUIRED

      According  to the  terms of the  Partnership  Agreement,  approval  of the
Proposal  requires  the  affirmative  vote by the holders of at least 51% of the
Units held by Limited  Partners.  Therefore,  an abstention by a Limited Partner
will have the same effect as a vote against the Proposal.  This  solicitation is
being made for votes in favor of the Proposal  (which will result in liquidation
and dissolution).  As of the Record Date, 53,405 Units were outstanding and were
held of record by 502 Limited Partners (excluding the Managing General Partner's
Units).  Each Limited  Partner is entitled to one vote for each Unit held in his
name on the Record  Date.  Accordingly,  the  affirmative  vote of holders of at
least 27,236.55 Units is required to approve the Proposal.  The Managing General
Partner  holds  3,547  Units,  but,  in  accordance  with  Article  XX.H  of the
Partnership Agreement,  the Managing General Partner may not vote its Units. The
Managing  General  Partner's  non-vote,  in  contrast to  abstention  by Limited
Partners,  will not affect the  outcome,  because for  purposes of adopting  the
Proposal its Units are excluded from the total number of voting Units.

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

PROXIES; REVOCATION

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

DISSENTERS' RIGHTS

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

PAYMENT OF LIQUIDATING DISTRIBUTIONS

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

SOLICITATION

      The  solicitation is being made by the  Partnership.  The Partnership will
bear  the  costs  of  the  preparation  of  this  Proxy  Statement  and  of  the
solicitation  of proxies  and such costs will be  allocated  90% to the  Limited
Partners  and  10% to  the  General  Partners  with  respect  to  their  general
partnership  interests  pursuant to Article  VIII.A(v).  As the Managing General
Partner  holds  approximately  6.26% of the Units held by all Limited  Partners,
6.26% of the costs borne by the Limited  Partners  will be borne by the Managing
General  Partner,  in  addition  to its  portion  borne  as a  General  Partner.
Solicitations  will be made primarily by mail. In addition to  solicitations  by
mail,  a number of regular  employees of the  Managing  General  Partner may, if
necessary  to ensure the presence of a quorum,  solicit  proxies in person or by
telephone.  The Managing  General  Partner also may retain a proxy  solicitor to
assist in  contacting  brokers or Limited  Partners to  encourage  the return of
proxies,  although  it does not  anticipate  doing so.  The costs of this  proxy
solicitation,  including  legal and accounting  fees and expenses,  printing and
mailing costs, and related costs are estimated to be approximately $30,000.

                                  RISK FACTORS

      Notwithstanding the following discussion,  there are risks involved in the
Proposal.  While  the  Managing  General  Partner  is not  aware of any  unknown
liabilities at this time, should any unexpected  liabilities come to light prior
to  making  the  final   liquidating   distribution,   such  liabilities   could
significantly  reduce,  or  eliminate   altogether,   such  final  distribution.
Anticipated sales prices for the properties may not be achieved. Should domestic
gas prices  strengthen  after the sales of the assets,  it is possible that more
advantageous sales prices for the properties might have been realized at a later
date. Furthermore, if the Partnership approves the proposal to sell its Property
Interests but the Pension  Partnership does not approve the sale of its Property
Interests  properties  and actually sell its  interests in the same  properties,
then the Partnership  will be forced to sell its working  interests  burdened by
the net profits  interest  owned by the Pension  Partnership.  Because  this may
affect  the  saleability  of the  Partnership's  Property  Interests,  it may be
necessary  for the  Managing  General  Partner  to  purchase  the  Partnership's
interests  in  such  properties.  Therefore,  the  likelihood  of  sale  of  the
Partnership's  Property Interests will be significantly  affected by the ability
of the Partnership and its companion Pension Partnership to sell their ownership
interests  in the same  properties  together,  which in turn is  dependent  upon
approval of the proposal being made to the Partnership and the similar  proposal
being made  simultaneously  to the  companion  Pension  Partnership.  Failure to
approve the proposal by either partnership could significantly  adversely affect
the  sale  of  properties  by  the  other   partnership.   See  "The  Proposal--
Simultaneous Proposal to Pension Partnership."

                                  THE PROPOSAL

GENERAL

      The  Managing   General  Partner  has  proposed  that  the   Partnership's
properties be sold, the  Partnership be dissolved and that the Managing  General
Partner, acting as liquidator,  wind up its affairs and make final distributions
to its partners.  The  Partnership's  assets  consist of working  interests (the
"Property Interests") in producing oil and gas properties, which are burdened by
a single net profits  interest owned by an affiliated  partnership (the "Pension
Partnership")  also  managed  by the  Managing  General  Partner  and  formed at
approximately the same time as the Partnership was organized.  The non-operating
net  profits  interest  was  granted  to Swift  Energy  Managed  Pension  Assets
Partnership  1990-C,  Ltd.  pursuant  to a Net Profits  and  Overriding  Royalty
Interest  Agreement  ("NP/OR  Agreement")  dated  September 30, 1990.  The NP/OR
Agreement gives the Pension  Partnership a net profits  interest in the group of
producing  properties  in which the  Partnership  owns  working  interests,  and
entitles  the Pension  Partnership  to receive a portion of the net profits from
operation of the group of producing  properties  owned by the Partnership  which
are  subject to the NP/OR  Agreement.  The net profits  percentage  to which the
Pension Partnership is entitled is based upon a percentage of the gross proceeds
(reduced by certain  costs) from the sale of oil and gas  production  from these
properties.

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

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

PARTNERSHIP FINANCIAL PERFORMANCE AND CONDITION

      The  Partnership  owns  Property   Interests  in  producing  oil  and  gas
properties  within  the  continental  United  States.  By the  end of  1991  the
Partnership  had  expended  all of its original  capital  contributions  for the
purchase of oil and gas producing  properties.  During 1996 approximately 86% of
the  Partnership's  revenue  was  attributable  to natural gas  production.  The
Partnership  has, from time to time,  performed  workovers and  recompletions of
Partnership  wells,  using funds  advanced by the  Managing  General  Partner to
perform  these  operations,  a portion of which  amounts  has been  subsequently
repaid from production.

      The  Limited  Partners  have  made  contributions  of  $5,695,200,  in the
aggregate  to the  Partnership.  The Managing  General  Partner has made capital
contributions  with  respect to its  general  partnership  interest  of $48,087.
Additionally,  pursuant to the  presentment  right set forth in Article XVIII of
the Partnership Agreement, it purchased 3,547 Units from Limited Partners.

      From inception  through  January 31, 1997, the  Partnership  has made cash
distributions to its Limited Partners totaling  $2,534,900.  Through January 31,
1997,  the Managing  General  Partner has received cash  distributions  from the
Partnership of $286,628 with respect to its general  partnership  interest,  and
distributions

related to its limited  partnership  interests of $11,051.  On a per Unit basis,
Limited Partners had received,  as of January 31, 1997, $44.51 per $100 Unit, or
approximately 44.51% of their initial capital contributions.

      The Partnership acquired its Property Interests at a time when oil and gas
prices and industry  projections of future prices were much higher than actually
occurred  in  subsequent  years.  As  detailed  in  the  Designated   Properties
Supplement dated September 12, 1990 regarding  Property Interests to be acquired
by the Partnership,  when the Managing General Partner  projected future oil and
gas prices to evaluate the economic viability of an acquisition, it compared its
forecasts  with  those made by banks,  oil and gas  industry  sources,  the U.S.
government,  and other companies  acquiring  producing  properties.  Acquisition
decisions for the Partnership were based upon a range of increasing  prices that
were within the  mainstream of the forecasts made by these outside  parties.  At
the time that the Partnership's Property Interests covering producing properties
were acquired,  prices averaged about $22.87 per barrel of oil and $2.04 per Mcf
of natural gas. Oil and gas prices were expected to escalate  during  subsequent
years of the Partnership's  operations.  In general, in 1990 and early 1991, all
of these sources forecasted increases in product prices that were based upon oil
and gas prices at the time,  which  reflected  the invasion of Kuwait by Iraq in
the summer of 1990 and the  commencement of hostilities in the Gulf War in 1991.
The majority of the  Partnership's  Property  Interests were acquired during the
fourth  quarter of 1990 and the first  quarter of 1991 when current  prices were
predicted to escalate  according to certain parameters from that level. Thus the
majority of properties were bought upon an evaluated  weighted  average price of
$2.04 per Mcf.  The  predicted  price  increases  did not occur and prices  fell
precipitously  from late 1991 to 1992.  The bulk of the  Partnership's  reserves
were produced from 1991-1995 during which time the  Partnership's  oil prices in
fact averaged  $16.41 per barrel and natural gas prices  averaged  approximately
$1.75 per Mcf.

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

         In addition to the effect of prices,  Partnership  performance has been
impacted by subsequent enhancement activities which were undertaken by the third
party  operator  of  certain  Partnership  properties.   The  benefit  of  these
enhancement  activities,  however,  was  reduced  by the need to repay the costs
incurred for these  enhancements.  The recoupment of costs took much longer than
anticipated due to lower than expected prices  subsequent to completion of these
activities.  Furthermore,  capital  limitations  resulted  in the  Partnership's
interests  in these  wells being  relatively  small and they thus did not have a
major positive effect on the Partnership's overall performance.

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

         As required by the Partnership Agreement,  the Partnership expended all
of the partners' net commitments  available for property acquisitions many years
ago to acquire  Property  Interests in  producing  oil and gas  properties.  The
Partnership's  net  revenues  available  for  distribution  have been reduced by
amounts used to pay operating and enhancement costs to the third party operator.
The Managing  General Partner  advanced most of these costs because it felt that
such  expenditures  would  increase  the  value of the  properties  in which the
Partnership has an interest.  The Partnership's  partnership  agreement does not
allow additional  assessments to be made against any Limited Partners.  No funds
are available at the current time from Partnership  revenues or other sources to
enable  the  Partnership  to make  additional  capital  expenditures  and no new
capital  expenditures are planned. The Managing General Partner anticipates that
if sales of the Partnership's  properties  occur,  there will be sufficient cash
generated  by the  sales  of  the  Partnership's  properties  to  make  a  final
liquidating distribution.

ESTIMATES OF LIQUIDATING DISTRIBUTION AMOUNT

         It is not  possible  to  accurately  predict  the  prices  at which the
Property Interests will be sold. The sales price of the Partnership's properties
may vary.  Certain  Property  Interests might sell for a higher price and others
for a lower  price than those  estimated  below.  The  projected  range of sales
prices  below  has  been  based  upon  estimated  future  net  revenues  for the
Partnership's Property Interests, using estimates of 1997 average prices without
any escalation.  The future net revenues from production of such properties have
then  been  discounted  to  present  value  at  10%  per  annum.  These  pricing
assumptions  vary from those mandated by the Securities and Exchange  Commission
("SEC") for reserves  disclosures under applicable SEC rules,  which require use
of prices at year-end, although the discount rate and lack of escalation are the
same. If estimates of reserves and future net revenues had been  prepared  using
December 31, 1996 prices, as mandated by the SEC, reserves,  future net revenues
and the present  value  thereof  would be  significantly  higher.  The  Managing
General  Partner has determined  not to use these higher prices because  current
estimates of 1997 average prices more  accurately  reflect prices  purchasers of
properties  are willing to pay,  rather than higher  values which do not reflect
the decrease in prices since year-end 1996.  For example,  the weighted  average
price of gas received by the Partnership for the first quarter of 1997 was $2.89
per Mcf, as compared to $4.72 per Mcf at December 31, 1996. For the lower end of
such projected  sales  proceeds,  the estimated sales proceeds have been further
discounted to 70% of those shown for the higher end of the range.

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

         Among  factors which can affect the ultimate  sales price  received for

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

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

COMPARISON OF SALE VERSUS CONTINUING OPERATIONS

         Based on the above tables, it is estimated that a Limited Partner could
expect to receive from $12.86 to $18.96 per $100 Unit upon immediate sale of the
Partnership  Property Interests.  In comparison,  it is estimated that a Limited
Partner could expect to receive  approximately $_____ per $100 Unit,  discounted
to present  value  ($19.93  per $100 Unit in actual  dollars on an  undiscounted
basis) over the life of its Property  Interests,  approximately 20 years, if the
Partnership continued operations.

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

REASONS FOR THE PROPOSAL

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

         Small  Amount  of  Remaining  Assets in  Relation  to  Expenses.  As of
December 31, 1996,  approximately 72% of the Partnership's  ultimate recoverable
reserves had been produced, and the Limited Partners' share of the Partnership's
interest in remaining reserves,  before any reduction for costs, is estimated to
be less than 1,376,000 Mcfe. The Partnership's share of oil and gas reserves are
expected  to  continue  to  decline  as   remaining   reserves   are   produced.
Distributions  to partners in recent years have declined and are not expected to
increase appreciably. Declines in well production are based principally upon the
maturity of the wells,  not on market  factors.  Each  producing well requires a
certain  amount of overhead  costs,  as  operating  and other costs are incurred
regardless  of the level of  production.  Likewise,  general and  administrative
expenses such as  compliance  with the  securities  laws,  producing  reports to
partners and filing  partnership tax returns do not decline as revenues decline.
As a result of the  depletion of the  Partnership's  oil and gas  reserves,  the
Managing  General Partner believes the  Partnership's  asset base and future net
revenues no longer justify the  continuation  of operations.  Consequently,  the
Managing General Partner expects that the Partnership will have to start selling
a portion of its Property Interests to pay the expenses of future operations and
administration. By accelerating the liquidation of the Partnership, those future
administrative  costs can be avoided and the receipt of the remaining cash value
of the interests of the Limited Partners in the Partnership can be accelerated.

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

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

         Orderly Sale of Properties  Through  Approval of the Proposal.  The oil
and gas market is volatile,  making the sale of the properties at optimal prices
very time sensitive.  Therefore,  the Managing General Partner believes that the
Partnership  should  liquidate and have the  flexibility  to sell its properties
when such sales appear to be most advantageous to the Partnership.  The approval
of the Proposal as it is set forth will provide the Managing General Partner the
flexibility to sell the remaining properties in an orderly fashion to maximize

                                                        11

the potential return to the Limited Partners. The approval of the Proposal would
also allow the Managing  General Partner to begin the winding up and dissolution
of the  Partnership  following  the  final  sale of  Partnership  property.  The
approval of the  Proposal  will act as the  approval  of all future  asset sales
without  the  approval by the Limited  Partners  of the  specific  terms of such
future sales.

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

SIMULTANEOUS PROPOSAL TO PENSION PARTNERSHIPS

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

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

         If the  Partnership  does not approve the  proposal  but its  companion
Pension  Partnership  approves  the  proposal to sell its  properties,  then the
Managing General Partner will attempt to sell the  non-operating  interest owned
by the Pension  Partnership to a third party. If no economic sale can be made to
a third party,  which may occur due to the  difficulty  in selling a net profits
interest in a property when  operating and spending  decisions are controlled by
another  entity,  then the  Managing  General  Partner  will  get a fair  market
appraisal  of the value of the Pension  Partnership's  net profits  interest and
will purchase the Pension Partnership's  non-operating  interests itself for the
highest price for which such interests are appraised.

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

STEPS TO IMPLEMENT THE PROPOSAL

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

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

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

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

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

                    2.   Pay  or  provide  for  payment  of  the   Partnership's
                         liabilities   and  obligations  to  creditors  (See  --
                         "Liquidation") using the Partnership's cash on hand and
                         proceeds from the sale of Partnership properties;

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

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

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

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

         Auction. The Managing General Partner (or a third party seller) intends
to engage the O&G  Clearinghouse  or  another  similar  company to conduct  live
auctions  for  the  sales  working   interests  of  the   Partnership   and  the
non-operating  interests of the Pension  Partnership.  The O&G Clearinghouse (as
well as other such auction companies) is in the business of conducting  auctions
for oil and gas properties. The O&G Clearinghouse establishes a data room, which
they  leave open for a period of time  (generally  three to four  weeks),  after
which  they  hold  a  live  auction.  The  O&G  Clearinghouse  requires  advance
registration for all


CORPHOU:9546.2  14323-00070

bidders.  Bidders may participate by invitation  only, after having qualified as
knowledgeable and sophisticated parties routinely or actively engaged in the oil
and gas  business.  The O&G  Clearinghouse  publishes a brochure  regarding  the
properties.  The O&G  Clearinghouse  is  headquartered  in  Houston,  Texas.  In
auctions  conducted by the O&G  Clearinghouse,  properties are generally grouped
into small packages with a single field often comprising a property.

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

         Negotiated Sale. Although the Managing General Partner intends to offer
the Partnership's and the Pension  Partnership's  Property Interests at auction,
it is possible  that the Managing  General  Partner or a third party engaged for
the purpose of selling the  Partnership's  assets may approach other oil and gas
companies  and  negotiate a sale of certain  Property  Interests.  The  Managing
General  Partner  (or such  third  party)  may  solicit  bids on the oil and gas
properties  for which the  Managing  General  Partner  is the  operator.  If the
Managing  General  Partner (or third party)  solicits  bids, it will provide all
interested  parties with information  about the properties needed to bid on such
properties.  Such information would include raw data and historical  information
on all of the operated  properties that any of the  partnerships  managed by the
Managing  General  Partner  intends  to sell.  See  "--Steps  to  Implement  the
Proposal." The data will be organized by property.  None of the Managing General
Partner's  other  partnerships  managed  by  the  Managing  General  Partner  or
affiliates of the Managing  General  Partner will purchase any of the properties
in this  manner.  In the event of a bid that is lower than a price the  Managing
General  Partner  believes is  reasonable,  it may sell the  property to a third
party  bidder for such lower bid price,  use  another  method of sale such as an
auction,  or have the  Partnership  continue to hold such  property  for a while
longer.  If the property has no appreciable  value, the Managing General Partner
may dispose of such property by conveying it to the operator or by conveying the
property to itself,  for no  consideration.  In no event is the Managing General
Partner obligated to purchase any of the Property Interests.

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

IMPACT ON THE MANAGING GENERAL PARTNER

         The  Managing   General  Partner  will  be  economically   impacted  by
liquidation  in at least two ways.  First,  to the  extent of its  ownership  of
Units,  liquidation will have the same effect on it as on the Limited  Partners.
See "--Estimate of Liquidating  Distribution  Amount," and "--Estimated Share of
Limited Partners' Net Distributions from Continued  Operations." Second, because
of the dissolution and liquidation of the Partnership, together with liquidation
of other  partnerships,  the  Managing  General  Partner will no longer hold the
majority  interest  in  various  wells.  Different  operators  are  likely to be
selected and the Managing  General  Partner will therefore lose revenues that it
currently realizes from its role as operator for those properties.  The Managing
General Partner is making its  recommendations  as set forth below, on the basis
of its fiduciary duty to the Limited  Partners,  rather than on the basis of the
direct economic impact on the Managing General Partner.

RECOMMENDATION OF THE MANAGING GENERAL PARTNER

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

         THE MANAGING GENERAL PARTNER  RECOMMENDS THAT THE LIMITED PARTNERS VOTE
FOR THE PROPOSAL.


                         FEDERAL INCOME TAX CONSEQUENCES

GENERAL

         The following summarizes certain federal income tax consequences to the
Limited Partners arising from the Partnership's proposed sale of its oil and gas
properties  and  liquidation  pursuant  to the  Proposal.  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  Partnership  constitutes a
partnership for federal tax purposes and that the Partnership will be liquidated
as described herein. The laws, regulations,  administrative rulings and judicial
decisions  which  form  the  basis  for  conclusions  with  respect  to the  tax
consequences  described  herein are complex and are  subject to  prospective  or
retroactive  change at any time and any  change  may  adversely  affect  Limited
Partners.

         This summary  does not  describe  all the tax aspects  which may affect
Limited  Partners  because  the tax  consequences  may vary  depending  upon the
individual  circumstances  of a Limited  Partner.  It is  generally  directed to
individual  Limited  Partners who are the original  purchasers  of the Units and
hold interests in the Partnership as "capital assets" (generally,  property held
for investment). Each Limited Partner that is 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

         Limited  Partners  will  realize  and  recognize  gain  or  loss,  or a
combination of both,  upon the  Partnership's  sale of its  properties  prior to
liquidation. The amount of gain realized with respect to each oil and gas


CORPHOU:9546.2  14323-00070
                                                        15

<PAGE>



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

         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 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 Partnership did not
incur  material  amounts of  intangible  drilling  and  development  costs,  and
accordingly the recapture of same is not expected to be material.

         Realized gains and losses  generally must be recognized and reported in
the year the sale occurs.  Accordingly,  each  Limited  Partner will realize and
recognize his  allocable  share of gains and losses in his tax year within which
the Partnership properties are sold. Each Limited Partner's recognized allocable
share of the net  Partnership  1231  gains or losses  must be  netted  with that
Limited Partner'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 a Limited
Partner in liquidation is less than such Limited Partner's adjusted tax basis in
his  Partnership  interest,  the Limited  Partner will  realize and  recognize a
capital loss to the extent of the excess.  If the amount of cash  distributed is
greater  than such  Limited  Partner's  adjusted  tax  basis in his  Partnership
interest, the Limited Partner will recognize a capital gain to the extent of the
excess. Because each Limited Partner paid a portion of syndication and formation
costs upon  entering  the  Partnership,  neither of which costs were  deductible
expenses,  it is anticipated that liquidating  distributions to Limited Partners
will be less than such Limited  Partners' bases in their  Partnership  interests
and thusly will generate capital losses.

CAPITAL GAIN TAX

         Net long-term capital gains of individuals,  trusts and estates will be
taxed at a maximum rate of 28%, while ordinarily  income,  including income from
the recapture of intangible  drilling and development  costs,  depreciation  and
depletion,  will be taxed at a maximum rate depending on that Limited  Partner's
taxable income of 36% or 39.6%.  With respect to net capital losses,  other than
Section 1231 net losses, the amount

of net  long-term  capital loss that can be utilized to offset  ordinary  income
will be limited to the sum of net capital gains from other sources recognized by
the Limited Partner during the tax year,  plus $3,000 ($1,500,  in the case of a
married  individual  filing a separate  return).  The excess  amount of such net
long-term  capital loss may be carried forward and utilized in subsequent  years
subject to the same limitations.

PASSIVE LOSS LIMITATIONS

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

         A Limited Partner's allocable share of Partnership income,  gain, loss,
and  deduction  is  treated as derived  from a passive  activity,  except to the
extent of Partnership  portfolio  income,  which includes  interest,  dividends,
royalty income and gains from the sale of property held for investment purposes.
A Limited Partner's  allocable share of any gain 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 the  Partnership  will  terminate  the  Limited
Partner's interest in the passive activity,  a Limited Partner's allocable share
of any loss (i) previously  realized as a Limited Partner in the Partnership and
suspended  because  of  its  passive  characterization,  (ii)  realized  on  the
liquidating  sale of  Partnership  properties,  or (iii) realized by the Limited
Partner upon liquidation of his Partnership interest,  will not be characterized
as losses from a passive activity.

         THE  FOREGOING  DISCUSSION  IS  FOR  GENERAL  INFORMATION  ONLY  AND IS
INTENDED  TO BE A SUMMARY OF CERTAIN  INCOME TAX  CONSIDERATIONS  OF THE SALE OF
PROPERTIES AND LIQUIDATION.  IT IS NOT INTENDED AS AN ALTERNATIVE FOR INDIVIDUAL
TAX PLANNING. EACH LIMITED PARTNER SHOULD CONSULT HIS OWN TAX ADVISOR CONCERNING
THE FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES TO HIM OF THE SALE
OF PROPERTIES AND THE LIQUIDATION OF THE PARTNERSHIP.

                           BUSINESS OF THE PARTNERSHIP

         The  Partnership is a Texas limited  partnership  formed  September 30,
1990.  Units  in the  Partnership  are  registered  under  Section  12(g) of the
Securities Exchange Act of 1934. In addition to the following  information about
the business of the Partnership, see the attached Annual Report on Form 10-K for
the year ended December 31, 1996, and its quarterly  report on Form 10-Q for the
first quarter of 1997, both included herewith.

RESERVES

                  For information  about the  Partnership's  interest in oil and
gas  reserves  and future net  revenue  expected  from the  production  of those
reserves as of December 31, 1996, see the attached report,  which was audited by
H. J. Gruy & Associates,  Inc., independent petroleum consultants.  It should be
noted that the reserve  estimates in the Annual  Report on Form 10-K reflect the
entire  Partnership  reserves and that the reserve report in the attached letter
from H. J. Gruy & Associates,  Inc. reflects only the Limited Partners' share of
the  Partnership's  estimated  oil and gas  reserves.  This  report has not been
updated to include the effect of production  since  year-end  1996,  nor has the
annual review of estimated quantities done each year-end taken place for 1997.

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

                  In estimating  the  Partnership's  interest in oil and natural
gas  reserves,  the Managing  General  Partner has used flat pricing  based upon
estimates of 1997 average prices, without escalation,  except in those instances
where fixed and  determinable  gas price  escalations  are covered by contracts,
limited  to the price the  Partnership  reasonably  expects  to  receive.  These
pricing  assumptions  vary from those  mandated by the  Securities  and Exchange
Commission  ("SEC") for reserves  disclosures under applicable SEC rules,  which
require  use of prices  at  year-end,  although  the  discount  rate and lack of
escalation  are the same.  If  estimates of reserves and future net revenues had
been prepared using December 31, 1996 prices, as mandated by the SEC,  reserves,
future net revenues and the present value thereof would be significantly higher.
The Managing  General  Partner has  determined  not to use these  higher  prices
because current estimates of 1997 average prices more accurately  reflect prices
purchasers of properties are willing to pay,  rather than higher values which do
not reflect  the  decrease in prices  since  year-end  1996.  For  example,  the
weighted  average  price of gas  received  by the  Partnership  during the first
quarter of 1997 was $2.89 per Mcf, as compared to $4.72 per Mcf at December  31,
1996.  The  Managing  General  Partner  does not believe  that any  favorable or
adverse event causing a significant  change in the estimated  quantity of proved
reserves set forth in the  attached  report has  occurred  between  December 31,
1996, and the date of this Proxy Statement.

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

THE MANAGING GENERAL PARTNER

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

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

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

TRANSACTIONS BETWEEN THE MANAGING GENERAL PARTNER AND THE PARTNERSHIP

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

         o        The  Managing  General  Partner   receives   per-well  monthly
                  operating  fees from the  Partnership  for  certain  producing
                  wells in which the Partnership owns Property Interests and for
                  which it  serves  as  operator  in  accordance  with the joint
                  operating agreements for each of such wells. The fees that are
                  set in the joint operating  agreements are negotiated with the
                  other working interest owners of the properties.

         o        The Managing  General Partner is entitled to be reimbursed and
                  has been  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   Limited   Partner   capital
                  contributions  to the Partnership  relative to limited partner
                  contributions  of all  partnerships  for  which  the  Managing
                  General Partner serves as Managing General Partner.

NO TRADING MARKET

         There is no  trading  market  for the Units,  and none is  expected  to
develop. Under the Partnership Agreement, the Limited Partners have the right to
present their Units to the Managing  General  Partner for  repurchase at a price
determined in accordance  with the formula  established  by Article XVIII of the
Partnership  Agreement.   Originally,  539  Limited  Partners  invested  in  the
Partnership.  Through  December  31,  1996,  the  Managing  General  Partner had
purchased  3,547  Units  from  Limited   Partners   pursuant  to  the  right  of
presentment.  As of June 1, 1997, there were 502 Limited Partners (excluding the
Managing General

Partner). The Managing General Partner does not have an obligation to repurchase
Limited  Partner  interests  pursuant to this right of presentment but merely an
option to do so when such interests are presented for repurchase.

PRINCIPAL HOLDERS OF LIMITED PARTNER UNITS

         The  Managing   General  Partner  holds  6.26%  of  the  Units  of  the
Partnership.  To the  knowledge of the  Managing  General  Partner,  there is no
holder of Units that holds more than 5% of the Units.

APPROVALS

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

LEGAL PROCEEDINGS

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

                                     PART I


Item 1.  Business

General Description of Partnership

         Swift Energy Income Partners 1990-C,  Ltd., a Texas limited partnership
(the "Partnership" or the "Registrant"),  is a partnership formed under a public
serial limited partnership offering denominated Swift Energy Income Partners III
(Registration  Statement No. 33-11773 on Form S-1, originally declared effective
March 19, 1987,  and amended  effective  March 28, 1988,  May 4, 1989 and May 1,
1990 [the  "Registration  Statement"]).  The  Partnership  was formed  effective
September 30, 1990 under a Limited  Partnership  Agreement  dated  September 30,
1990. The initial 539 limited partners made capital contributions of $5,695,200.

         The  Partnership is  principally  engaged in the business of acquiring,
developing and, when  appropriate,  disposing of working interests in proven oil
and gas properties  within the continental  United States.  The Partnership does
not  engage  in  exploratory  drilling.   Each  working  interest  held  by  the
Partnership entitles the Partnership to receive, in kind or in value, a share of
the  production  of oil and gas from the producing  property,  and obligates the
Partnership  to  participate  in the  operation  of the property and to bear its
proportionate share of all operating costs associated therewith. The Partnership
typically  holds  less  than  the  entire  working  interest  in  its  producing
properties.

         At December  31,  1996,  the  Partnership  had expended or committed to
expend 100% of the limited  partners' net commitments  (i.e.,  limited partners'
commitments available to the Partnership for property acquisitions after payment
of  organization  fees and  expenses)  in the  acquisition  and  development  of
producing properties, which properties are described under Item 2, "Properties,"
below. The  Partnership's  revenues and profits are derived almost entirely from
the  sale of oil and gas  produced  from  its  properties  and  from the sale of
acquired  oil  and  gas  properties,   when  the  sale  of  such  properties  is
economically preferable to continued operation.

         The  Partnership's  business and affairs are  conducted by its Managing
General  Partner,  Swift Energy  Company,  a Texas  corporation  ("Swift").  The
Partnership's Special General Partner, VJM Corporation, a California corporation
("VJM"),  consults with and advises Swift as to certain financial matters. Swift
is the designated  operator of many of the  properties in which the  Partnership
owns  interests.  The remaining  properties  are operated by industry  operators
designated by the owners of a majority of the working interest in each property.

         The  general  manner  in  which  the  Partnership   acquires  producing
properties  and  otherwise  conducts  its business is described in detail in the
Registration Statement under "Proposed Activities," which is incorporated herein
by reference.  The following is intended only as a summary of the  Partnership's
manner of doing business and specific activities to date.

Manner of Acquiring Properties; Net Profits and Overriding Royalty
Interest Agreement

         For the sake of legal and  administrative  convenience,  the  producing
properties  owned by the Registrant  have  typically been acquired  initially by
Swift,  which then conveyed  ownership of each such property to the  Registrant.
The  Registrant  acquires  producing  properties  from  Swift  at  the  property
acquisition  cost of such  properties  to Swift,  as  adjusted  for  intervening
operations.

         The  Registrant  entered  into a Net  Profits  and  Overriding  Royalty
Interest  Agreement dated September 30, 1990 (the "NP/OR  Agreement") with Swift
Energy  Managed   Pension  Assets   Partnership   1990-C,   Ltd.  (the  "Pension
Partnership").  The Pension  Partnership is a Texas limited  partnership that is
also  managed by Swift and VJM.  The Pension  Partnership  was formed to acquire
nonoperating  interests,  such as net profits,  royalty and  overriding  royalty
interests, in producing oil and gas properties.

         Under the NP/OR Agreement,  the Registrant and the Pension  Partnership
have, in effect,  combined their funds in acquiring producing properties;  using
funds  committed to the NP/OR  Agreement by both  partnerships,  the  Registrant
acquires  producing  properties,  then promptly conveys  nonoperating  interests
therein  to  the  Pension   Partnership.   The  Registrant  initially  committed
$5,200,650  and the  Pension  Partnership  initially  committed  $3,072,822  for
acquisitions  under the NP/OR  Agreement.  The Registrant is obligated under the
NP/OR  Agreement  to convey to the Pension  Partnership  a 37% fixed net profits
interest and a variable overriding royalty interest in specified depths of every
producing  property it  acquires,  except  that (i)  properties  anticipated  to
require  significant  development  operations,  and (ii) nonoperating  interests
offered to the  Registrant by third  parties may be purchased by the  registrant
outside the NP/OR Agreement,  without  participation by the Pension Partnership.
The  Registrant is entitled to withdraw up to 30% of its  committed  funds under
the NP/OR Agreement for such acquisitions.

         All properties  acquired by the Registrant  since the date of the NP/OR
Agreement have been acquired subject to the NP/OR Agreement and the nonoperating
interests created thereby. At December 31, 1996, the Registrant had not made any
withdrawals   to  acquire   properties   anticipated   to  require   significant
development.

         In accordance with its  obligations  under the NP/OR  Agreement,  as of
December 31, 1996 the Registrant  had conveyed to the Pension  Partnership a net
profits interest burdening certain depths of all producing  properties  acquired
by the  Registrant  since  the date of the  NP/OR  Agreement.  Typically,  a net
profits  interest in an oil and gas  property  entitles the owner to a specified
percentage share of the gross proceeds generated by the burdened  property,  net
of  operating  costs.  The 37% net  profits  interest  conveyed  to the  Pension
Partnership  under the NP/OR  Agreement  differs  from the  typical  net profits
interest in that it is calculated over the entire group of producing  properties
acquired under the NP/OR  Agreement;  i.e., all operating costs  attributable to
the burdened  depths of such  properties are  aggregated,  and the total is then
subtracted  from the total of all gross proceeds  attributable to such depths in
order to calculate the net profits to which the Pension Partnership is entitled.
The net profits interest conveyed to the Pension  Partnership burdens only those
depths of each subject  property which were evaluated to contain proved reserves
at the date of acquisition, to the extent such depths underlie specified surface
acreage.

         The Registrant has also conveyed to the Pension  Partnership  under the
NP/OR agreement an overriding  royalty interest in each property  acquired since
the date of the NP/OR Agreement.  An overriding royalty interest is a fractional
interest in the gross  production (or the gross  proceeds  therefrom) of oil and
gas  from  a  property,  free  of any  exploration,  development,  operation  or
maintenance expenses. Under the NP/OR Agreement, the overriding royalty interest
burdens the portions of each producing  property that were evaluated at the date
of acquisition not to contain proved reserves.

Competition, Markets and Regulations

         Competition

         The oil and gas industry is highly  competitive in all its phases.  The
Partnership encounters strong competition from many other oil and gas producers,
many of which possess substantial financial resources, in acquiring economically
desirable Producing Properties.

         Markets

         The amounts of and price  obtainable  for oil and gas  production  from
Partnership  Properties will be affected by market factors beyond the control of
the  Partnership.  Such factors include the extent of domestic  production,  the
level of imports of foreign oil and gas, the general level of market demand on a
regional, national and worldwide basis, domestic and foreign economic conditions
that  determine  levels of industrial  production,  political  events in foreign
oil-producing  regions, and variations in governmental  regulations and tax laws
and  the  imposition  of new  governmental  requirements  upon  the  oil and gas
industry. There can be no assurance that oil and gas prices will not decrease in
the future, thereby decreasing net Revenues from Partnership Properties.

         From time to time,  there may exist a  surplus  of  natural  gas or oil
supplies,  the effect of which may be to reduce the amount of hydrocarbons  that
the  Partnerships may produce and sell while such oversupply  exists.  In recent
years,  initial steps have been taken to provide  additional gas  transportation
lines from Canada to the United States. If additional Canadian gas is brought to
the United States market, it could create downward pressure on United States gas
prices.

         Regulations

         Environmental Regulation

         The federal  government  and various state and local  governments  have
adopted  laws and  regulations  regarding  the control of  contamination  of the
environment.  These laws and regulations may require the acquisition of a permit
by Operators before drilling commences,  prohibit drilling activities on certain
lands  lying  within  wilderness  areas or where  pollution  arises  and  impose
substantial  liabilities for pollution  resulting from operations,  particularly
operations near or in onshore and offshore waters or on submerged  lands.  These
laws and  regulations  may also  increase  the  costs of  routine  drilling  and
operation of wells.  Because these laws and regulations change  frequently,  the
costs to the  Partnership of compliance  with existing and future  environmental
regulations cannot be predicted.  However, the Managing Partner does not believe
that the  Partnership is affected in a significantly  different  manner by these
regulations than are its competitors in the oil and gas industry.

         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 summary of the principal statutes,  regulations
and  orders  that  may  affect  the  production  and  sale of  natural  gas from
Partnership  Properties.  This  summary  should not be relied upon as a complete
review of applicable natural gas regulatory provisions.

         FERC Orders

         Several major  regulatory  changes have been implemented by the Federal
Energy Regulatory  Commission  ("FERC") from 1985 to the present 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. The
rule imposes these same requirements upon storage facilities.

         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 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 natural gas production from  Partnership  Properties  will be  significantly
affected  by FERC  Order No.  500.  Gas  produced  from  Partnership  Properties
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 pipeline transportation.

         State Regulations

         Production  of any oil  and gas  from  Partnership  Properties  will be
affected  to some  degree  by  state  regulations.  Many  states  in  which  the
Partnership will operate 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
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 Partnership'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,
exploration and development plans, methods of operation and related matters.

Employees

         The  Partnership  has no  employees.  Swift,  however,  has a staff  of
geologists,   geophysicists,   petroleum  engineers,   landmen,  and  accounting
personnel who  administer  the  operations of Swift and the  Partnership.  As of
December 31, 1996, Swift had 191 employees.  Swift's administrative and overhead
expenses  attributable  to  the  Partnership's   operations  are  borne  by  the
Partnership.

Item 2.  Properties

         As of December  31, 1996,  the  Partnership  has acquired  interests in
producing oil and gas properties which are generally described below.

Principal Oil and Gas Producing Properties

         The most  valuable  fields  in the  Partnership,  based  upon  year-end
engineering  estimates of discounted  future net revenues using constant pricing
and costs, are described below.

         1. The  Velrex  Field is  located  in  Schleicher  County,  Texas,  and
accounts for 33% of the value in this  Partnership.  Wells in this field produce
from the Henderson and Canyon Sands, (Sugarland acquisition).

         The remaining  value in the  Partnership  is  attributable  to numerous
properties  none of which equals or exceeds 15 percent of the total  Partnership
value.

Title to Properties

         Title to  substantially  all  significant  producing  properties of the
Partnership has been examined. The properties are subject to royalty, overriding
royalty and other  interests  customary in the  industry.  The Managing  General
Partner does not believe any of these burdens  materially detract from the value
of the properties or will materially detract from the value of the properties or
materially  interfere  with their use in the  operation  of the  business of the
Partnership.

Production and Sales Price

         The following table  summarizes the sales volumes of the  Partnership's
net oil and gas production  expressed in MCFs.  Equivalent  MCFs are obtained by
converting oil to gas on the basis of their relative energy content;  one barrel
equals 6,000 cubic feet of gas.

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

         In estimating  the oil and natural gas  reserves,  the  Registrant,  in
accordance with criteria  prescribed by the Securities and Exchange  Commission,
has used prices received as of December 31, 1996 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  Registrant  does not believe that any  favorable or adverse event
causing a significant  change in the estimated  quantity of proved  reserves has
occurred between December 31, 1996 and the date of this report.

         Future prices received for the sale of the  Partnership's  products may
be higher or lower than the prices used in the evaluation  described  above; the
operating  costs relating to such  production may also increase or decrease from
existing  levels.  The estimates  presented  above are in accordance  with rules
adopted by the Securities and Exchange Commission.

Item 3. Legal Proceedings

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

Item 4. Submission of Matters to a Vote of Security Holders

         No matters  were  submitted  to a vote of limited  partners  during the
fourth quarter of the fiscal year covered by this report.

Item 5.  Market Price of and Distributions on the Registrant's Units and
         Related Limited Partner Matters

Market Information

         Units in the  Partnership  were  initially  sold at a price of $100 per
Unit.  Units are not traded on any exchange and there is no  established  public
trading  market for the Units.  Swift is aware of negotiated  transfers of Units
between  unrelated  parties;  however,  these  transfers  have been  limited and
sporadic.  Due to the  nature of these  transactions,  Swift  has no  verifiable
information regarding prices at which Units have been transferred.

Holders

         As of December 31, 1996,  there were 539 Limited Partners holding Units
in the Partnership.

Distributions

         The Partnership  generally makes distributions to Limited Partners on a
quarterly  basis,   subject  to  the  restrictions  set  forth  in  the  Limited
Partnership Agreement. In the fiscal years ended December 31, 1995 and 1996, the
Partnership  distributed  a total of $72,700 and $140,000,  respectively  to the
holders of its Units.  Cash  distributions  constitute net proceeds from sale of
oil and gas  production  after  payment of lease  operating  expenses  and other
partnership expenses.  Some or all of such amounts or any proceeds from the sale
of partnership  properties  could be deemed to constitute a return of investors'
capital.

         Oil and gas  investments  involve a high risk of loss, and no assurance
can be given that any particular  level of distributions to holders of Units can
be  achieved  or  maintained.   Although  it  is   anticipated   that  quarterly
distributions  will continue to be made through 1997, the Partnership's  ability
to make distributions  could be diminished by any event adversely  affecting the
oil and gas properties in which the Partnership  owns interests or the amount of
revenues received by the Partnership therefrom.

         The  Partnership's   Limited  Partnership  Agreement  contains  various
provisions  which might serve to delay,  defer or prevent a change in control of
the Partnership,  such as the requirement of a vote of Limited Partners in order
to  sell  all  or  substantially  all  of the  Partnership's  properties  or the
requirement of consent by the Managing  General  Partner to transfers of limited
partnership  interests  and  provisions  prohibiting  the  transfer  of  Limited
Partnership  Units  in any  fiscal  year in  excess  of a limit  which  has been
established in order to comply with certain federal income tax regulations.

Item 7. Management's Discussion and Analysis of Financial Condition and
        Results of Operations

Liquidity and Capital Resources

         The  Partnership  has expended  all of the  partners'  net  commitments
available for property  acquisitions and development by acquiring  producing oil
and gas  properties.  The  partnership  invests  primarily  in proved  producing
properties  with nominal  levels of future costs of  development  for proven but
undeveloped reserves.  Significant purchases of additional reserves or extensive
drilling activity are not anticipated. Oil and gas reserves are depleting assets
and therefore often experience  significant  production  declines each year from
the date of acquisition through the end of the life of the property. The primary
source of liquidity to the  Partnership  comes almost  entirely  from the income
generated from the sale of oil and gas produced from ownership  interests in oil
and gas  properties.  This  source  of  liquidity  and the  related  results  of
operations will decline in future periods as the oil and gas produced from these
properties also declines.

         Subject to 1997 market conditions  remaining  comparable with 1996, the
Managing  General  Partner  anticipates  an increase in liquidity  provided that
certain  development  work  scheduled  in 1997 is  completed  successfully.  The
Partnership plans to spend in 1997 an estimated $65,000 for capital expenditures
needed  for this  development  work and the  enhancement  of proved  oil and gas
reserves.  The Managing  General Partner  anticipates  that the Partnership will
have adequate  liquidity from income from  continuing  operations to satisfy any
future capital  expenditure  requirements.  Funds generated from bank borrowings
and proceeds from the sale of oil and gas properties  will be used to supplement
this effort if deemed necessary.

Results of Operations

         Oil and gas sales  increased 9 percent in 1996 vs.  1995.  Increases in
both 1996 gas and oil prices were major contributors to the increased  revenues.
The Partnership  experienced an increase in gas prices of 40 percent or $.58/MCF
and an increase  in oil prices of 21 percent or  $3.26/BBL.  The  average  sales
price per  equivalent  MCF  increased  30  percent in 1996.  Production  volumes
decreased 15 percent due to a 41 percent oil production decrease and a 8 percent
gas production  decline.  The production declines partially offset the effect of
increased oil and gas prices impacting partnership performance.

         Production cost per equivalent MCF decreased 4 percent in 1996 compared
to 1995 and total production costs decreased 17 percent in 1996.

         Oil and gas sales  decreased  33 percent in 1995 vs.  1994.  Production
volumes  decreased 23 percent due to a 25 percent gas production  decrease and a
10 percent oil  production  decline.  Since the  Partnership's  reserves  are 87
percent gas,  the  decrease in gas  production,  due to  accelerated  production
declines on mature  wells,  a reduction in  development  drilling in the current
year and production  curtailments due to declining prices, had a major impact on
partnership  performance.  A decline  in the 1995 gas  prices of 24  percent  or
$.45/MCF  further  contributed  to the  Partnership's  decreased  revenues.  The
average sales price per equivalent MCF decreased 15 percent in 1995.


                                      II-2


<PAGE>

                   SWIFT ENERGY INCOME PARTNERS 1990-C, LTD.


         Production cost per equivalent MCF decreased 4 percent in 1995 compared
to 1994. In addition, total production costs decreased 26 percent in 1995.

         Associated  depreciation  expense  decreased  40  percent  in 1995 when
compared to 1994.

         The  Partnership  recorded an  additional  provision  in  depreciation,
depletion and  amortization in 1995 and 1994 when the present value,  discounted
at ten percent,  of estimated  future net revenues from oil and gas  properties,
using the guidelines of the Securities  and Exchange  Commission,  was below the
fair  market  value  paid for oil and gas  properties  resulting  in a full cost
ceiling impairment.

         During 1997,  Partnership revenues and costs will be shared between the
limited partners and general partners in a 90:10 ratio,  based on the annualized
rate of cash  distributions by the Partnership  during a certain period prior to
December 31, 1996.  Based on current oil and gas prices,  current  levels of oil
and gas  production  and expected cash  distributions  during 1997, the Managing
General Partner  anticipates that the Partnership sharing ratio will continue to
be 90:10.

         From time to time, Swift as Managing General Partner of the Partnership
purchases Units in the  Partnership  from investors who offer the Units pursuant
to their right of  presentment,  which  purchases are made pursuant to terms set
out in the  Partnership's  original Limited  Partnership  Agreement.  Due to the
frequency  and  large  number  of  these   transactions,   Swift  reports  these
transactions  under  Section  16 of the  Securities  Exchange  Act of 1934 on an
annual  rather than a monthly  basis.  In some cases such annual  reporting  may
constitute a late filing of the required Section 16 reports under the applicable
Section 16 rules.

Item 11.  Executive Compensation

         As  noted  in  Item  10,  "Directors  and  Executive  Officers  of  the
Registrant,"  above,  the Partnership has no executive  officers.  The executive
officers of Swift and VJM are not compensated by the Partnership.

         Certain fees and  allowances  contemplated  by the Limited  Partnership
Agreement  have been paid by the  Partnership  to Swift and VJM. See Note (4) in
Notes  To  Financial   Statements   (Related-Party   Transactions)  for  further
discussion.

Item 12.  Security Ownership of Certain Beneficial Owners and Management

         Swift Energy Company,  the Managing General  Partner,  located at 16825
Northchase  Drive,   Suite  400,  Houston,   Texas  77060,  owns  3,565  Limited
Partnership Units, which is 6.26 percent of all outstanding  Limited Partnership
Units. All Limited Partnership Units owned by Swift were acquired from investors
who  offered  the  Limited   Partnership   Units  pursuant  to  their  right  of
presentment.  As the Managing General Partner, Swift is not permitted generally,
under the Limited Partnership Agreement,  to vote its Limited Partnership Units.
Swift also owns a general  partnership  interest of 9 percent of all partnership
interests in the Partnership.

         Swift and VJM are not aware of any arrangement,  the operation of which
may at a subsequent date result in a change in control of the Partnership.

Item 13.  Certain Relationships and Related Transactions

         As  noted  in  Item  10,  "Directors  and  Executive  Officers  of  the
Registrant," above, the Partnership has no executive officers or directors,  and
thus has not  engaged  in any  transactions  in which  any  such  person  had an
interest.  The Partnership is permitted to engage in certain  transactions  with
Swift as Managing General Partner and VJM as Special General Partner, subject to
extensive  guidelines and restrictions  described in the "Conflicts of Interest"
section of the Amended Prospectus contained in the Registration Statement, which
is incorporated herein by reference.

         Summarized  below are the  principal  transactions  that have  occurred
between the Partnership and Swift, VJM and their affiliates.

         1. The oil and gas properties acquired by the Partnership, as described
in Item 2, "Properties"  above, were typically  acquired initially by Swift from
the  seller  thereof  and  subsequently  transferred  to the  Partnership.  Such
transfers  were made by Swift at its Property  Acquisition  Costs (as defined in
the  Limited  Partnership  Agreement),  less any amounts  received  from sale of
production  between the time of acquisition by Swift and the time of sale to the
Partnership.

         2.  Swift  acts  as  operator  for  many  of the  wells  in  which  the
Partnership  has  acquired  interests  and has  received  compensation  for such
activities in accordance with standard industry operating agreements.

         3. The  Partnership  paid to Swift and VJM certain fees as contemplated
by the  Limited  Partnership  Agreement.  See Note  (4) in  Notes  To  Financial
Statements (Related-Party Transactions) for further discussion.

is to express an opinion on these 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 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 Income
Partners 1990-C,  Ltd., as of December 31, 1996 and 1995, and the results of its
operations  and its cash flows for the years ended  December 31, 1996,  1995 and
1994, in conformity with generally accepted accounting principles.

                    SWIFT ENERGY INCOME PARTNERS 1990-C, LTD.
                          NOTES TO FINANCIAL STATEMENTS


(1) Organization and Terms of Partnership Agreement -

         Swift Energy Income Partners 1990-C,  Ltd., a Texas limited partnership
(the  Partnership),  was  formed on  September  30,  1990,  for the  purpose  of
purchasing and operating producing oil and gas properties within the continental
United States.  Swift Energy Company  ("Swift"),  a Texas  corporation,  and VJM
Corporation ("VJM"), a California corporation, serve as Managing General Partner
and  Special  General  Partner of the  Partnership,  respectively.  The  general
partners  are  required  to  contribute  up to 1/99th  of  limited  partner  net
contributions.  The 539 limited  partners  made total capital  contributions  of
$5,695,200.

         Property  acquisition costs and the management fee are borne 99 percent
by the limited  partners and one percent by the general  partners.  Organization
and syndication costs were borne solely by the limited partners.

         Initially, all continuing costs (including development costs, operating
costs,  general  and  administrative  reimbursements  and direct  expenses)  and
revenues are allocated 90 percent to the limited partners and ten percent to the
general partners. If prior to partnership payout, as defined,  however, the cash
distribution rate for a certain period equals or exceeds 17.5 percent,  then for
the  following  calendar  year,  these  continuing  costs and  revenues  will be
allocated  85  percent to the  limited  partners  and 15 percent to the  general
partners. After partnership payout, continuing costs and revenues will be shared
85 percent by the limited partners, and 15 percent by the general partners, even
if the cash distribution rate is less than 17.5 percent. Payout had not occurred
as of December 31, 1996.

(2) Significant Accounting Policies -

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 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.

Oil and Gas Properties --

         For  financial   reporting   purposes,   the  Partnership  follows  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 years
ended December 31, 1996, 1995 and 1994.

         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
Partnership's 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  Partnership,  limited
partners,  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,  and the lower of
cost or fair value of unproved properties. 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.


                                      IV-8


<PAGE>

                    SWIFT ENERGY INCOME PARTNERS 1990-C, LTD.
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)


         The Partnership computes 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 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.

Statements of Cash Flows --

         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
Partnership's oil and gas operations:

                                  --------        --------       --------
</TABLE>


         All oil and gas  property  acquisitions  are made by Swift on behalf of
the Partnership. The costs of the properties include the purchase price plus any
costs incurred by Swift in the evaluation and acquisition of properties.

         During  1995  and  1994,  the  Partnership's  unamortized  oil  and gas
property costs exceeded the quarterly  calculations of the "ceiling  limitation"
resulting  in  an   additional   provision  for   depreciation,   depletion  and
amortization  of  $417,905  and  $1,142,899,   respectively.  In  computing  the
Partnership's third quarter 1994 "ceiling limitation",  the Partnership utilized
the  product  prices in effect  at the date of the  filing of the  Partnership's
report on Form 10-Q.  Utilizing these subsequent prices, the write down recorded
by the  Partnership  was  $659,872  less than the  amount  that  would have been
recorded  using  product  prices in effect at September  30, 1994. No such write
downs were required in 1996.

         In addition,  the limited  partners'  share of unamortized  oil and gas
property costs exceeded their "ceiling  limitation" in 1995 and 1994,  resulting
in a valuation allowance of $370,152 and $1,000,733,  respectively.  This amount
is included in the income (loss)  attributable to the limited  partners shown in
the statement of partners'  capital  together with a "combining  adjustment" for
the  difference  between  the  limited  partners'  valuation  allowance  and the
Partnership's valuation allowance.  The "combining adjustment" changes quarterly
as the Partnership's total depreciation, depletion and amortization provision is
more  or  less  than  the  combined  depreciation,  depletion  and  amortization
provision attributable to general and limited partners.

(4) Related-Party Transactions -

         An  affiliate  of the  Special  General  Partner,  as  Dealer  Manager,
received   $141,508  for  managing  and   overseeing  the  offering  of  limited
partnership units.

         A one-time  management  fee of  $142,380  was paid to Swift in 1990 for
services  performed  for the  Partnership.  During  1996,  1995  and  1994,  the
Partnership paid Swift $78,034, $46,966 and $75,884,  respectively, as a general
and administrative overhead allowance.

         Effective  September  30,  1990,  the  Partnership  entered  into a Net
Profits and Overriding Royalty Interest Agreement ("NP/OR Agreement") with Swift
Energy Managed Pension Assets Partnership  1990-C,  Ltd. (Pension  Partnership),
managed by Swift for the purpose of acquiring working interests in producing oil
and gas properties.  Under the terms of the NP/OR Agreement, the Partnership has
conveyed to the Pension Partnership a nonoperating interest in the aggregate net
profits  (i.e.,  oil  and gas  sales  net of  related  operating  costs)  of the
properties acquired equal to its proportionate share of the property acquisition
costs.

(5) Note Payable to a Bank -

      Note payable to a bank at December 31, 1996 and 1995 follows:

</TABLE>


         Note was  paid in full at  maturity.  As  provided  by the  Partnership
Agreement,  the note  payable was  obtained  to fund  development  wells.  As of
December 31, 1996, the Partnership had no outstanding note payable to a Bank.

(6) Federal Income Taxes -

         The Partnership is not a tax-paying entity. No provision is made in the
accounts of the Partnership 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  Partnership income are
subject to  examination  by the federal  and state  taxing  authorities.  If the
Partnership's  ordinary  income for federal  income tax  purposes is  ultimately
changed by the taxing  authorities,  the tax  liability of the limited  partners
could be changed  accordingly.  Ordinary  income  reported on the  Partnership's
federal  return of income for the years ended  December 31, 1996,  1995 and 1994
was  $429,938,  $202,609 and  $363,644,  respectively.  The  difference  between
ordinary income for federal income tax purposes  reported by the Partnership and
net income or loss  reported  herein  primarily  results  from the  exclusion of
depletion  (as  described   below)  from   ordinary   income   reported  in  the
Partnership's federal return of income.


                                     IV-10


<PAGE>

                    SWIFT ENERGY INCOME PARTNERS 1990-C, LTD.
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)


         For federal  income tax purposes,  depletion with respect to production
of  oil  and  gas  is  computed  separately  by  the  partners  and  not  by the
Partnership.  Since the amount of depletion on the  production of oil and gas is
not  computed  at  the  Partnership  level,  depletion  is not  included  in the
Partnership's  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.

(7) Gas Imbalances -

         The gas imbalance receivable and deferred revenues represent imbalances
assumed as part of property  acquisitions.  The  imbalances are accounted for on
the entitlements  method,  whereby the Partnership records its share of revenue,
based on its entitled amount.  Any amounts over or under the entitled amount are
recorded as an increase or decrease to the gas imbalance  receivable or deferred
revenues as applicable.

(8) Vulnerability Due to Certain Concentrations -

         The Partnership'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.

         The Partnership  extends credit 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 Partnership's  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 Partnership  extends  credit.  In addition,
the  Partnership  generally  does not require  collateral  or other  security to
support customer receivables.

(9) Fair Value of Financial Instruments -

         The  Partnership's  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

                                   (UNAUDITED)


(1)  General Information -

                  The financial statements included herein have been prepared by
        the  Partnership  and are  unaudited  except  for the  balance  sheet at
        December  31,  1996  which has been  taken  from the  audited  financial
        statements at that date. The financial  statements reflect  adjustments,
        all of which were of a normal recurring nature, which are in the opinion
        of the  managing  general  partner  necessary  for a fair  presentation.
        Certain  information  and  footnote  disclosures  normally  included  in
        financial  statements  prepared in accordance  with  generally  accepted
        accounting  principles  have  been  omitted  pursuant  to the  rules and
        regulations  of the  Securities  and Exchange  Commission  ("SEC").  The
        Partnership  believes adequate disclosure is provided by the information
        presented.  The financial  statements should be read in conjunction with
        the audited  financial  statements  and the notes included in the latest
        Form 10-K.

(2)  Organization and Terms of Partnership Agreement -

                  Swift Energy  Income  Partners  1990-C,  Ltd., a Texas limited
        partnership ("the  Partnership"),  was formed on September 30, 1990, for
        the purpose of purchasing and operating producing oil and gas properties
        within the continental United States. Swift Energy Company ("Swift"),  a
        Texas   corporation,   and  VJM   Corporation   ("VJM"),   a  California
        corporation,  serve as Managing  General  Partner  and  Special  General
        Partner of the  Partnership,  respectively.  The  general  partners  are
        required   to   contribute   up  to  1/99th  of  limited   partner   net
        contributions. The 539 limited partners made total capital contributions
        of $5,695,200.

                  Property acquisition costs and the management fee are borne 99
        percent by the limited partners and one percent by the general partners.
        Organization  and  syndication  costs were borne  solely by the  limited
        partners.

                  Generally,  all continuing costs (including development costs,
        operating costs,  general and  administrative  reimbursements and direct
        expenses) and revenues are allocated 90 percent to the limited  partners
        and ten percent to the general partners. If prior to partnership payout,
        however,  the cash  distribution  rate for a  certain  period  equals or
        exceeds  17.5  percent,  then for the  following  calendar  year,  these
        continuing  costs and  revenues  will be  allocated  85  percent  to the
        limited  partners  and  15  percent  to  the  general  partners.   After
        partnership  payout,  continuing  costs and  revenues  will be shared 85
        percent by the limited partners, and 15 percent by the general partners,
        even if the cash distribution rate is less than 17.5 percent.

(3)  Significant Accounting Policies -

       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  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.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                   (UNAUDITED)


     Oil and Gas Properties --

                  For financial  reporting purposes the Partnership  follows 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 three  months  ended
        March 31, 1997 and 1996.

                  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  Partnership's  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  Partnership,
        limited  partners 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,  and the lower of cost or fair  value of  unproved  properties.
        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  Partnership  computes  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  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.

(4)  Related-Party Transactions -

                  An  affiliate  of  the  Special  General  Partner,  as  Dealer
        Manager,  received  $141,508 for managing and overseeing the offering of
        the limited partnership units. A one-time management fee of $142,380 was
        paid to Swift for services performed for the Partnership.

                  Effective  September 30, 1990, the Partnership  entered into a
        Net  Profits  and  Overriding   Royalty   Interest   Agreement   ("NP/OR
        Agreement") with Swift Energy Managed Pension Assets Partnership 1990-C,
        Ltd.  (Pension  Partnership),  managed  by  Swift  for  the  purpose  of
        acquiring working  interests in producing oil and gas properties.  Under
        terms of the  NP/OR  Agreement,  the  Partnership  has  conveyed  to the
        Pension Partnership a nonoperating interest in the aggregate net profits
        (i.e.,  oil  and  gas  sales  net of  related  operating  costs)  of the
        properties  acquired  equal to its  proportionate  share of the property
        acquisition costs.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                   (UNAUDITED)


(5)  Gas Imbalances -

                  The  gas  imbalance   receivable  and  deferred  revenues  are
        accounted  for on  the  entitlements  method,  whereby  the  Partnership
        records its share of revenue,  based on its entitled amount. Any amounts
        over or under  the  entitled  amount  are  recorded  as an  increase  or
        decrease  to the  gas  imbalance  receivable  or  deferred  revenues  as
        applicable.

(6)  Vulnerability Due to Certain Concentrations -

                  The  Partnership'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.

                  The Partnership extends credit 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  Partnership's  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 Partnership  extends credit.  In addition,  the Partnership
        generally  does not  require  collateral  or other  security  to support
        customer receivables.

(7)  Fair Value of Financial Instruments -

                  The Partnership's  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.

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



General

      The  Partnership  was formed for the purpose of investing in producing oil
and gas properties  located within the  continental  United States.  In order to
accomplish  this,  the  Partnership  goes through two  distinct yet  overlapping
phases  with  respect  to its  liquidity  and  result  of  operations.  When the
Partnership  is formed,  it commences its  "acquisition"  phase,  with all funds
placed in short-term  investments until required for such property acquisitions.
The interest  earned on these  pre-acquisition  investments  becomes the primary
cash flow source for initial partner distributions.  As the Partnership acquires
producing   properties,   net  cash  from  operations   becomes   available  for
distribution,  along with the investment  income.  After  partnership funds have
been expended on producing oil and gas properties,  the  Partnership  enters its
"operations" phase. During this phase, oil and gas sales generate  substantially
all revenues,  and  distributions  to partners  reflect those  revenues less all
associated  partnership expenses.  The Partnership may also derive proceeds from
the sale of acquired oil and gas properties, when the sale of such properties is
economically appropriate or preferable to continued operation.

Liquidity and Capital Resources

      The  Partnership  has  completed  acquisition  of  producing  oil  and gas
properties, expending all of the limited partners' net commitments available for
property acquisitions.

      The  Partnership  does  not  allow  for  additional  assessments  from the
partners  to fund  capital  requirements.  However,  funds  are  available  from
partnership  revenues,  borrowings  or  proceeds  from the  sale of  partnership
property.  The  Managing  General  Partner  believes  that the  funds  currently
available to the Partnership  will be adequate to meet any  anticipated  capital
requirements.

Results of Operations

     Oil and gas sales  increased  $18,710 or 13 percent in the first quarter of
1997 when  compared to the same period in 1996,  primarily  due to increased gas
and oil prices.  An increase in gas prices of 55 percent or $1.03/MCF and in oil
prices of 22  percent  or  $3.80/BBL  had a  significant  impact on  partnership
performance.  Current  quarter  oil  production  declined  63  percent  and  gas
production  declined 4 percent when  compared to first  quarter 1996  production
volumes, partially offsetting the effect of increased gas and oil prices.

      Associated depreciation expense decreased 19 percent or $9,655.

      During 1997,  partnership  revenues  and costs will be shared  between the
limited partners and general partners in a 90:10 ratio.

Gentlemen:

At your request,  we have made an audit of the reserves and future net cash flow
as of December 31, 1996,  prepared by Swift Energy Company ("Swift") for certain
interests  owned by the limited  partners in Swift Energy Income Partners 1990-C
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.  The estimated net
reserves,  future  net  cash  flow  and  discounted  future  net  cash  flow are
summarized by reserve category as follows:

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 federal income tax.

In the economic  projections,  prices,  operating  costs and  development  costs
remain constant for the projected life of each lease. For these projections, the
oil and gas  prices  were  assumed  to be $21.00  per barrel and $2.25 per MMBTU
respectively.

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.  The proved reserves in
this report conform to the applicable definitions  promulgated by the Society of
Petroleum  Engineers  and  the  Society  of  Petroleum   Evaluation   Engineers.
Attachment  I,  following  this  letter,  sets  forth  all  reserve  definitions
incorporated in this study.

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, 1996, except in those instances in which data were
available  through December.  Interim  production to December 31, 1996, 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.

In order to audit  the  reserves,  costs and  future  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.
