                          NOTES TO FINANCIAL STATEMENTS
                                   (UNAUDITED)

(1)  General Information -

                  The  limited   partners  of  the   Partnership   approved  the
        dissolution  of the  Partnership  on March 30,  2000.  As a result,  the
        Partnership  has changed its basis of  accounting,  effective  March 31,
        2000, from historical  cost basis to the  liquidation  basis.  Under the
        liquidation basis of accounting,  the Partnership's  assets at March 31,
        2000  are  reported  at  estimated  net   realizable   value,   and  the
        Partnership's liabilities are presented at estimated settlement amounts.
        The net  effect  of the  revaluation  of the  Partnership's  assets  and
        liabilities due to the adoption of the  liquidation  basis of accounting
        was an upward adjustment of $739,381.

                  Oil and gas  properties at March 31, 2000 reflect the Managing
        General  Partner's  estimate  of value,  in the  absence of third  party
        appraisals  or  evaluations,   based  on  future  net  revenues  of  the
        properties,  discounted  at 10%, as of March 31, 2000.  This estimate is
        based on its assessment of the impact of selling  existing  assets based
        on current  market  conditions  and estimated  disposal  costs.  The net
        proceeds from the sales of oil and gas properties may vary substantially
        due to changes in oil and gas prices,  subsequent  production  and other
        factors which may be applied by buyers.

                  For  all  other  assets  and  liabilities   presented  on  the
        liquidation  basis of accounting,  the Managing General Partner believes
        that  historical  cost   approximates  fair  market  value  due  to  the
        short-term nature of such assets and liabilities.

                  The accompanying  statements of operations and cash flows were
        prepared using the historical cost basis of accounting.

                  The financial statements included herein have been prepared by
        the  Partnership  and are  unaudited  except  for the  balance  sheet at
        December  31,  1999  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)  Gas Imbalances -

                  The Partnership  recognizes its ownership  interest in natural
        gas  production as revenue.  Actual  production  quantities  sold may be
        different than the  Partnership's  ownership share in a given period. If
        the  Partnership's  sales exceed its ownership share of production,  the
        differences are recorded as deferred revenue. Gas balancing  receivables
        are  recorded  when the  Partnership's  ownership  share  of  production
        exceeds sales.

(3)  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.

                  In the normal  course of  business,  the  Partnership  extends
        credit,  primarily in the form of monthly oil and gas sales receivables,
        to various  companies  in the oil and gas  industry  which  results in a
        concentration  of credit risk. This  concentration of credit risk may be
        affected by changes in economic or other  conditions and may accordingly
        impact the  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.

(4)  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.

                    SWIFT ENERGY INCOME PARTNERS 1987-A, LTD.
                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.

Liquidation

      During the first quarter of 2000, the Managing  General  Partner  informed
the limited partners of a proposal to sell all of the Partnership's interests in
oil and gas properties and dissolve and liquidate the  Partnership.  The special
meeting of limited partners was held on March 30, 2000.

      Of the total  units held by the  limited  partners,  a majority  voted for
adoption of the  proposal  for sales of  substantially  all of the assets of the
Partnership and the dissolution,  winding up and termination of the Partnership.
The  Partnership  adopted the  liquidation  basis of  accounting  for the period
subsequent to March 31, 2000.

Liquidity and Capital Resources

      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,   and  in  turn  cash
distributions,  will decline in future  periods as the oil and gas produced from
these properties also declines while  production and general and  administrative
costs remain relatively stable making it unlikely that the Partnership will hold
the properties  until they are fully depleted,  but will likely liquidate when a
substantial  majority of the reserves have been produced.  Cash distributions to
partners are determined quarterly, based upon net proceeds from sales of oil and
gas production after payment of lease operating  expense,  taxes and development
costs, less general and administrative expenses. In addition, future partnership
cash requirements are taken into account to determine necessary cash reserves.

      Net cash provided by operating  activities totaled $28,043 and $30,248 for
the three months ended March 31, 2000 and 1999, respectively. Cash distributions
totaled  $24,870 and $31,974 for the three months ended March 31, 2000 and 1999,
respectively.

      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.  The  Partnership  does not  allow for
additional  assessments  from the  partners to fund  capital  requirements.  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.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


      After sale of all its interests in oil and gas  properties  and settlement
of its liabilities,  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.

Results of Operations

      Oil and gas sales increased $54,827 or 121 percent in the first quarter of
2000 when compared to the corresponding  quarter in 1999.  Increased oil and gas
prices had a significant impact on Partnership performance. Oil prices increased
149 percent or $15.61/BBL to an average of $26.09/BBL  and gas prices  increased
101 percent or  $1.50/MCF to an average of  $2.99/MCF  for the quarter.  Current
quarter  production  volumes  increased  4  percent  as oil and  gas  production
increased 14 percent and 1 percent, respectively, when compared to first quarter
1999 production volumes.

      Corresponding  production costs per equivalent MCF increased 21 percent in
the  first  quarter  of 2000  compared  to the first  quarter  of 1999 and total
production costs increased 25 percent.

      Associated  depreciation  expense  decreased  10 percent or $3,340 in 2000
compared to first quarter 1999.

      The Partnership records an additional provision in depreciation, depletion
and amortization 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,  is below the fair market value  originally
paid for oil and gas  properties.  Using prices in effect at March 31, 1999, the
Partnership would have recorded an additional provision at March 31, 1999 in the
amount of $34,400.  However,  these temporarily low quarter-end prices rebounded
and by using prices in effect at the filing date, the Partnership's  unamortized
cost of oil and gas properties were not limited by this calculation.

      During 2000,  partnership  revenues  and costs will be shared  between the
limited partners and general partners in a 90:10 ratio.
