                          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,  1997  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.   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 Managed Pension Assets Partnership 1988-1,  Ltd.,
        a Texas limited partnership ("the Partnership"), was formed on September
        14, 1988, for the purpose of purchasing net profits interest, overriding
        royalty  interests and royalty  interests  (collectively,  "nonoperating
        interests") in 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 190 limited  partners
        made total capital contributions of $1,874,876.

                  Nonoperating  interests  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. Certain reclassifications have been
        made to prior year amounts to conform to the current year presentation.

       Nonoperating Interests in Oil and Gas Properties --

                  The Partnership accounts for its ownership interest in oil and
        gas properties using the proportionate consolidation method, whereby the
        Partnership's  share of assets,  liabilities,  revenues  and expenses is
        included in the appropriate classification in the financial statement.

                          SWIFT ENERGY MANAGED PENSION
                         ASSETS PARTNERSHIP 1988-1, LTD.
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                   (UNAUDITED)


                  For financial  reporting purposes the Partnership  follows the
        "full-cost"  method of accounting for nonoperating  interests in oil and
        gas property costs. Under this method of accounting,  all costs incurred
        in the acquisition of  nonoperating  interests in oil and gas properties
        are capitalized.  The unamortized cost of nonoperating  interests in 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 nonoperating interests
        in proved  properties  using current  prices  discounted at ten percent.
        Proceeds from the sale or disposition of  nonoperating  interests in oil
        and  gas  properties  are  treated  as a  reduction  of the  cost of the
        nonoperating  interests  with no gains or  losses  recognized  except in
        significant transactions.

                  The Partnership computes the provision for 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  by an overall rate  determined  by dividing the
        physical  units of oil and gas  produced  during the period by the total
        estimated 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  $46,872 for managing and  overseeing the offering of
        the limited  partnership units. A one-time management fee of $46,872 was
        paid to Swift for services performed for the Partnership.

                  Effective  September 14, 1988, the Partnership  entered into a
        Net  Profits  and  Overriding   Royalty   Interest   Agreement   ("NP/OR
        Agreement") with Swift Energy Income Partners 1988-1,  Ltd.  ("Operating
        Partnership"),   managed  by  Swift,   for  the  purpose  of   acquiring
        nonoperating interests in producing oil and gas properties.  Under terms
        of the NP/OR  Agreement,  the Operating  Partnership  will convey to the
        Partnership  nonoperating  interests 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)  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.

(6)  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  is formed for the purpose of investing  in  nonoperating
interests 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 results of
operations.  When the  Partnership  is formed,  it commences  its  "acquisition"
phase,  with all funds placed in short-term  investments  until required for the
acquisition of nonoperating interests.  Therefore,  the interest earned on these
pre-acquisition  investments  becomes the  primary  cash flow source for initial
partner  distributions.  As the Partnership acquires  nonoperating  interests in
producing properties,  net cash from ownership of nonoperating interests becomes
available  for  distribution,  along  with  the  investment  income.  After  all
partnership funds have been expended on nonoperating  interests in producing oil
and gas properties,  the Partnership enters its "operations"  phase. During this
phase,  income  from  nonoperating  interests  in oil  and gas  sales  generates
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  nonoperating  interests  in  acquired  oil and gas
properties,  when the sale of such  interests  is  economically  appropriate  or
preferable to continued operations.

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.  Net cash
provided by operating  activities  totaled $4,079 and $33,900 for the six months
ended June 30, 1998 and 1997,  respectively.  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.  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.  Cash  distributions  totaled
$22,944  and  $19,712  for  the  six  months  ended  June  30,  1998  and  1997,
respectively.

      Under the NP/OR Agreement, the Managing General Partner acquires interests
in oil and gas properties  from outside  parties and sells these interests to an
affiliated  operating  partnership,  who  in  turn  creates  and  sells  to  the
Partnership  nonoperating  interests in these same oil and gas  properties.  The
Managing General Partner expects funds derived from net profits  interests to be
distributed to the partners.

RESULTS OF OPERATIONS

      The  following  analysis  explains  changes  in the  revenue  and  expense
categories  for the quarter ended June 30, 1998 (current  quarter) when compared
to the quarter  ended June 30,  1997  (corresponding  quarter),  and for the six
months ended June 30, 1998  (current  period),  when  compared to the six months
ended June 30, 1997 (corresponding period).

Three Months Ended June 30, 1998 and 1997

      Income  from  nonoperating  interests  decreased  54 percent in the second
quarter of 1998 when  compared  to the same  quarter in 1997.  Oil and gas sales
declined $6,938 or 46 percent in the second quarter of 1998 when compared to the
corresponding   quarter  in  1997,  primarily  due  to  decreased  gas  and  oil
production.  Gas production  decreased 39 percent and oil production declined 71
percent.  The  decrease  in  production  volumes  had a  significant  impact  on
partnership  performance.  The partnership's  sale of several properties in 1997
had an impact on 1998 partnership  production volumes. Also, current quarter gas
and oil  prices  declined  6 percent or  $.11/MCF  and 37 percent or  $6.17/BBL,
respectively, further contributing to decreased revenues.

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


      Associated  amortization  expense  decreased  43 percent or $2,561 in 1998
compared to the second  quarter 1997,  also related to the decline in production
volumes.

Six Months Ended June 30, 1998 and 1997

      Income from nonoperating  interests  decreased 75 percent in the first six
months  of 1998 when  compared  to the same  period  in 1997.  Oil and gas sales
declined  $35,966 or 69 percent in the first six months of 1998 when compared to
the corresponding period in 1997, primarily due to decreased gas and oil prices.
A decline  in gas  prices of 38  percent  or  $1.00/MCF  and in oil prices of 32
percent or $6.19/BBL, had a significant impact on partnership performance. Also,
current  period  gas and oil  production  declined  50 percent  and 72  percent,
respectively,  when compared to the same period in 1997, further contributing to
decreased revenues.  The partnership's sale of several properties in 1997 had an
impact on 1998 partnership production volumes.

      Associated  amortization  expense  decreased  54 percent or $8,512 in 1998
compared  to the first six  months  of 1997,  also  related  to the  decline  in
production volumes.

      During 1998,  partnership  revenues  and costs will be shared  between the
limited partners and general partners in a 90:10 ratio.
