                SPECIAL COMMITTEE OF MCNEIL INVESTORS, INC.
                 ANNOUNCES REJECTION OF INCREASED OFFER FOR
                      MCNEIL REAL ESTATE FUND XX, L.P.
                          BY BOND PURCHASE, L.L.C.

        DALLAS, Texas, January 29, 2000 - The Special Committee of the
Board of Directors of McNeil Investors, Inc., which is the general partner
of McNeil Partners, L.P., which is in turn the General Partner of McNeil
Real Estate Fund XX, L.P. (the "Partnership"), announced today that it had
determined to recommend to the Board of Directors of McNeil Investors, Inc.
that it reject an increase cash tender offer from Bond Purchase, LLC and
reaffirm its recommendation that limited partners of the Partnership
approve the Whitehall transaction. On January 26, 2000, Bond Purchase
announced that it was increasing its tender offer to $110 per Unit. The
Special Committee said it had considered carefully the increased offer from
Bond Purchase and had again requested information from Bond Purchase
regarding certain aspects of its offer, including a request that Bond
Purchase provide its financial statements to the limited partners to permit
all those considering its tender offer to evaluate fully whether or nor to
retain their investments. By letter received yesterday, Bond Purchase again
declined to comply with the request, and so the Special Committee
determined that it could not endorse the increased offer from Bond
Purchase. The Special Committee also stated that it would continue to
monitor developments, and would evaluate any material changes which may
occur prior to the special meeting of limited partners scheduled for
February 2, 2000.

               On June 25, 1999, McNeil Partners, L.P. and WXI/McN Realty
L.L.C., an affiliate of Whitehall Street Real Estate Limited Partnership
XI, a real estate investment fund managed by Goldman, Sachs & Co., entered
into an acquisition agreement whereby the Whitehall affiliate will acquire
by merger nineteen real estate limited partnerships operated by McNeil
Partners, L.P. and Robert A. McNeil, including the Partnership (the
"Whitehall transaction"). The Whitehall transaction is described in detail
in the Proxy Statement first mailed to limited partners on or about
December 14, 1999 as supplemented on or about January 13, 2000 and January
25, 2000. If the Partnership participates in the Whitehall transaction,
limited partners will receive an aggregate of $105 per unit of limited
partnership interests (including the estimated amount of the special
distribution). A special meeting of limited partners to consider and vote
on the proposal described more fully in the Proxy Statement is scheduled
for:

               Wednesday, February 2, 2000
               11:00 a.m., local time
               Four Times Square
               38th Floor
               New York, New York 10036

               McNeil Partners and the special committee of the Board of
Directors of the corporate General Partner each remains committed to the
Whitehall transaction and continues to believe that the Whitehall
transaction is fair to, and in the best interests of, the Partnership and
its limited partners. Accordingly, the Board of Directors of McNeil
Investors continues to recommend that limited partners of each of the
McNeil Partnerships approve the Whitehall transaction.

               Limited partners with questions are encouraged to call the
Investor Services department of McNeil Partners, L.P. at 1-800-576-7907.
