                          Notes to Financial Statements

                                   (Unaudited)

(1)    Financial Statements

       These financial statements have been prepared in accordance with
       generally accepted accounting principles. The financial information
       included in these financial statements is unaudited, however, in
       management's opinion, all normal recurring adjustments necessary for a
       fair presentation of the results of operations for the periods included
       have been made.

       Footnote disclosures which would substantially duplicate those contained
       in the December 31, 1997 audited financial statements have been omitted
       from this report.

(2)    Sale of Properties

       On March 31, 1997, Medical Income Properties 2A Limited Partnership (the
       "Partnership") closed the sale of its interest in its seven remaining
       long-term care facilities in Alabama, Texas and Illinois, and the
       personal property and intangible assets related to the operation of those
       facilities (the "Properties"). The Properties in Alabama and Texas were
       sold to Omega Healthcare Investors, Inc., a Maryland corporation
       ("Omega"), pursuant to the asset Purchase and Sale Agreement dated as of
       February 3, 1997 (the "Sale Agreement"), by and among the Partnership,
       Qualicorp Management, Inc., the managing general partner of the
       Partnership, and Omega previously reported by the Partnership. The
       Properties in Illinois were sold to OHI (Illinois), Inc. an Illinois
       corporation ("OHI"), because of an assignment of certain rights of Omega
       to OHI under the Sale Agreement.

       Aggregate net proceeds from the sale of the Properties was $20,552,089,
       which was held by the escrow agent at March 31, 1997. The net proceeds
       and other assets of the Partnership will be distributed to the Limited
       Partners of the Partnership in the anticipated liquidation of the
       Partnership as described in the Partnership's Current Report on Form 8-K
       dated February 18, 1997.

       In connection with the closing of the sale of the Properties, the
       Partnership entered into an interim lease of the Properties pursuant to
       the terms of the Sale Agreement and under which the Partnership will
       provide for management and operation of the Properties for an interim
       period. The interim lease was terminated on May 31, 1997.

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


Liquidity and Capital Resources

Cash and equivalent balances totaled $1,445,443 as of March 31, 1998, a decrease
of $75,501 compared to December 31, 1997. This decrease was primarily due to
settlement of various vendors accounts payable reduced by collections of
accounts receivable.

The Partnership will make a final distribution of any remaining funds following
the expiration of the periods within which claims for breach of representations
and warranties and claims by Medicare, Medicaid or other third parties may be
made against the Partnership either by contract or under applicable law.

Operations

The Partnership's net loss for the quarter ended March 31, 1998 was $13,113.

Interest income totaled $39,125 for the quarter while the joint venture partners
recorded a loss of $5,052. Minority interest income for the quarter was $5,884.
Discontinued operating expense was $53,070 for the period ended March 31, 1998.
The comparison between quarters shows substantial differences primarily due to
the Partnership suspending all business operations on May 31, 1997.
