                         NOTES TO FINANCIAL STATEMENTS
                                  (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, 1995 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.

         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 six months ended June 30, 1996 and 1995.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                  (UNAUDITED)


                 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 will convey 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)      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 Company's revenues are primarily the result of sales of
         its oil and natural gas production.  Market prices of oil and natural
         gas may fluctuate and adversely affect operating results.

                                  (UNAUDITED)


                 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 Partners believes that the funds currently
available to the partnership will be adequate to meet any anticipated capital
requirements.

RESULTS OF OPERATIONS

     The following analysis explains changes in the revenue and expense
categories for the quarter ended June 30, 1996 (current quarter) when compared
to the quarter ended June 30, 1995 (corresponding quarter), and for the six
months ended June 30, 1996 (current period), when compared to the six months
ended June 30, 1995 (corresponding period).

THREE MONTHS ENDED JUNE 30, 1995 AND 1994

     Oil and gas sales increased $98,734 or 61 percent in the current quarter
of 1996 when compared to the corresponding quarter in 1995, primarily due to
increased gas and oil prices.  An increase in gas prices of 25 percent or
$.39/MCF and in oil prices of 8 percent or $1.17/BBL had a significant impact
on partnership performance.  Also, current quarter gas production increased 53
percent when compared to second quarter 1995 production volumes, further
contributing to increased revenues.

     Associated depreciation expense increased 67 percent or $39,285.

                CONDITION AND RESULTS OF OPERATIONS (CONTINUED)



SIX MONTHS ENDED JUNE 30, 1996 AND 1995

     Oil and gas sales increased $84,654 or 27 percent in the first six months
of 1996 over the corresponding period in 1995.  An increase in gas prices of 33
percent or $.48/MCF and in oil prices of 9 percent or $1.42/BBL were major
contributing factors to the increased revenues for the period.  Current period
oil production decreased 21 percent when compared to the corresponding period
in 1995, partially offsetting the effect of increased gas and oil prices.

     Associated depreciation expense increased 15 percent or $19,620.

     The Partnership recorded an additional provision in depreciation,
depletion and amortization in the first six months of 1995 for $375,339 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 originally paid for oil
and gas properties.  The additional provision results from the Managing General
Partner's determination that the fair market value paid for properties may or
may not coincide with reserve valuations determined according to guidelines of
the Securities and Exchange Commission.

      During 1996, partnership revenues and costs will be shared between the
limited partners and general partners in a 90:10 ratio.
