                          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  ("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 Managed Pension Assets Partnership 1989-2,  Ltd.,
        a Texas limited partnership ("the Partnership"), was formed on September
        30,  1989,  for  the  purpose  of  purchasing  net  profits   interests,
        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  Partners,   Ltd.   ("VJM"),   a  Texas  limited
        partnership,  serve as Managing  General  Partner  and  Special  General
        Partner of the Partnership,  respectively.  The Managing General Partner
        is  required  to  contribute  up  to  1/99th  of  limited   partner  net
        contributions. The 182 limited partners made total capital contributions
        of $1,676,058.

                  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.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                   (UNAUDITED)


     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 statements.

                  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 -

                  Affiliates of the Special General Partner,  as Dealer Manager,
        received $41,901 for managing and overseeing the offering of the limited
        partnership  units.  A one-time  management  fee of $41,901  was paid to
        Swift for services performed for the Partnership.

                  The  Partnership  entered  into a Net Profits  and  Overriding
        Royalty Interests Agreement ("NP/OR Agreement") with Swift Energy Income
        Partners 1989-3, 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 Partnership has been
        conveyed 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.

                                   (UNAUDITED)


(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  $27,701 and
$166,207 for the three months ended March 31, 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
the  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   partner's  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 $37,882 and $58,201 for the three months
ended March 31, 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.

RESULTS OF OPERATIONS

         Income from  nonoperating  interests  decreased 63 percent in the first
quarter of 1998 when  compared  to the same  quarter in 1997.  Oil and gas sales
declined $36,343 or 57 percent in the first quarter of 1998 when compared to the
corresponding  quarter in 1997, primarily due to decreased gas and oil prices. A
decline in gas prices of 43 percent or $1.24/MCF and in oil prices of 34 percent
or $7.01/BBL had a significant impact on partnership performance.  Also, current
quarter gas and oil production declined 40 percent and 30 percent,  respectively
when compared to first quarter 1997 production volumes,  further contributing to
decreased  revenues.  Sale of the  Gladewater  gas unit in Gregg  County,  Texas
(Cairn Acquisition) had an impact on 1998 partnership production volumes.

         Total  amortization  expense  decreased  20  percent  or $2,387 in 1998
compared  to first  quarter  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 an 85:15 ratio.
