McNeil Partnerships to Merge With an Affiliate of Whitehall

DALLAS, Texas, June 25, 1999 -- McNeil Partners,  L.P., a privately held sponsor
of real  estate  partnerships,  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.,  today  announced  that they have entered
into a definitive  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.  The limited  partnerships  involved are
McNeil Real Estate Funds IX, X, XI, XII, XIV, XV, XX, XXI,  XXII,  XXIII,  XXIV,
XXV,  XXVI and XXVII,  Hearth  Hollow  Associates,  McNeil  Midwest  Properties,
Regency   North   Associates,   Fairfax   Associates   and   McNeil   Summerhill
(collectively,  the  "Partnerships").   The  Partnerships  (other  than  Fairfax
Associates and McNeil  Summerhill which are wholly-owned by Robert A. McNeil and
related  parties) will be merged with  subsidiaries of WXI/McN Realty L.L.C. The
acquisition agreement also provides for the acquisition by WXI/McN Realty of the
assets of McNeil  Real  Estate  Management,  Inc.  ("McREMI"),  the real  estate
investment and management  company controlled by Robert A. McNeil. The aggregate
consideration in the transaction, including all outstanding mortgage debt of the
Partnerships, is approximately $644,440,000.

Pursuant to the terms of the acquisition agreement, the limited partners in each
of the  Partnerships  (other than those  wholly-owned  by Robert A. McNeil) will
receive  cash on the  closing  date of the  transaction  in  exchange  for their
limited partnership interests. In addition, each Partnership will make a special
distribution  to its limited  partners on the  closing  date of the  transaction
equal to its then net positive  working capital balance.  McNeil Partners,  L.P.
will  receive  an  equity  interest  in  WXI/McN  Realty  in  exchange  for  its
contribution  of its general  partnership  interests  in the  Partnerships,  the
limited partnership interests in its wholly owned Partnerships and the assets of
McREMI.

The proposed  transaction  follows an extensive  marketing effort by PaineWebber
Incorporated, exclusive financial advisor to the Partnerships.

The  transaction  has been  unanimously  approved by the Board of  Directors  of
McNeil  Investors,  Inc.,  the general  partner of McNeil  Partners,  L.P.,  the
general partner of each of the  Partnerships  other than Regency North,  Fairfax
Associates and McNeil  Summerhill.  The respective  general  partners of Regency
North,   Fairfax  Associates  and  McNeil  Summerhill  also  have  approved  the
transaction. The Board of Directors of McNeil Investors based its approval upon,
among other  things,  the  recommendation  of a Special  Committee of the Board,
appointed at the beginning of the  discussions  with  Whitehall to represent the
interests  of  holders  of  limited   partnership   interests  in  each  of  the
Partnerships.  In  addition,  the Special  Committee  and the Board  relied upon
fairness  opinions given by Robert A. Stanger & Co., Inc.  ("Stanger & Co."), an
independent  financial  advisor  to the  Partnerships,  to the  effect  that the
aggregate  consideration  is  fair  to the  holders  of each  class  of  limited
partnership   interests   in   each   Partnership.   The   Special   Committee's
recommendation  was also  based upon the  separate  opinions  of Eastdil  Realty
Company, the independent  financial advisor to the Special Committee.  Stanger &
Co.  and  Eastdil  have  each  also  rendered  an  opinion  that  the  aggregate
consideration  to be paid for the  general  partnership  interests  and  limited
partnership  interests  in all of the  Partnerships  and the assets of McREMI is
fair from a  financial  point of view to the  holders  of each  class of limited
partnership interests in each of the Partnerships.




Each  Partnership's  participation in the transaction is subject to, among other
conditions,  the  approval  by a  majority  of  the  limited  partners  of  that
Partnership.  The approval of the limited partners of the  Partnerships  will be
sought at  meetings  to be held in the coming  months  after the filing of proxy
statements  with the  Securities  and  Exchange  Commission  with respect to the
publicly traded Partnerships,  and the subsequent mailing of proxy statements to
the limited partners.

The aggregate  consideration in the transaction has been allocated preliminarily
among the general partnership interests and the limited partnership interests in
each of the Partnerships and McREMI,  based upon an allocation analysis prepared
by Stanger & Co. and confirmed by Eastdil.  Based upon this allocation  analysis
and the fairness  opinions  rendered by Stanger & Co. and  Eastdil,  the Special
Committee,  the Board of Directors of McNeil Investors,  the respective  general
partners of Regency North,  Fairfax  Associates and McNeil  Summerhill have each
unanimously  approved  the  allocation  of  the  aggregate  consideration.   The
estimated  aggregate  consideration  and  working  capital  distribution  to  be
received per unit of limited  partnership  interest,  is currently  estimated as
follows:

                                                             Estimated

                                                    Working Capital Distribution

McNeil Partners,  L.P. will contribute its real estate investment and management
company  business to a  subsidiary  of WXI/McN  Realty,  L.L.C.,  along with its
general  partnership  interests in the Partnerships and its limited  partnership
interests in the wholly-owned Partnerships, having an aggregate allocated value,
as  determined  by  Stanger  &  Co.,  of  approximately  $58,640,000,  of  which
approximately  $29,400,000  reflects  balances due to McNeil and  affiliates  as
reflected on the Partnership financial statements as of March 31, 1999.

The above estimates of the per unit estimated merger  consideration  and working
capital  distribution and the interest of McNeil Partners,  L.P. are based upon,
among other things,  the balance sheet of each Partnership as of March 31, 1999,
adjusted for intangible assets,  non-cash liabilities,  transaction expenses and
the McNeil Partners,  L.P.  interest in each  Partnership.  The McNeil Partners,
L.P.  interest  in each  Partnership  includes  all  amounts  payable  to McNeil
Partners,  L.P. as  reflected  on the balance  sheet as of March 31,  1999,  the
McNeil  Partners,  L.P. general  partnership  interest in respect of its capital
contribution less the deficit  restoration  obligation of McNeil Partners,  L.P.
pursuant to the partnership agreements.  Actual amounts,  including the estimate
allocable  to McNeil  Partners,  L.P.,  will vary  with the  performance  of the
Partnership  and McNeil  Partners,  L.P.  through  the closing  date.  The above
estimated merger  consideration and special working capital distribution will be
adjusted  at  closing to  reflect  the then  working  capital  position  of each
Partnership.

Robert and Carole McNeil stated that:  "We are very pleased to have entered into
this  transaction  that will  result in the  McNeil  Partnerships  being sold to
Whitehall on a basis which we believe is very favorable to our limited partners.
The price reflects the quality and  dedication of our management  team who, over
the past 8 years, have worked to optimize the value of these properties. We also
believe that this transaction will provide shorter term liquidity to our limited
partners than would have been obtainable had the partnerships been liquidated on
an individual basis."

fund and is the  seventh  in a series  of funds  sponsored  and  capitalized  by
