GLENDALE,  California--Public  Storage Properties XX, Inc. (AMEX:PSZ) and Public
Storage,  Inc.  (NYSE:PSA)  announced  today that the  corporations  had agreed,
subject to certain conditions, to merge. In the merger, PSZ would be merged with
and into PSA, and each outstanding share of PSZ's Common Stock Series A would be
converted, at the election of the shareholders of PSZ, into either shares of PSA
Common  Stock or, with respect to up to 20% of the PSZ Common  Stock,  $22.57 in
cash.  This dollar amount has been based on PSZ's estimated net asset value (the
appraised  value of PSZ's  real  estate  assets  as of  October  1, 1997 and the
estimated book value of PSZ's other net assets as of April 1998).  The number of
shares of PSA Common Stock will be based on dividing  this same dollar amount by
the average of the per-share closing prices on the New York Stock Exchange for a
specified period prior to PSZ's shareholders'  meeting.  The number of shares of
PSA's Common Stock  issued in the merger and the amount  receivable  upon a cash
election will be reduced by the amount of cash distributions required to be paid
to PSZ's  shareholders  by PSZ  prior to  completion  of the  merger in order to
satisfy PSZ's REIT distribution requirements.  Additional distributions would be
made to  shareholders  of PSZ to cause PSZ's estimated net asset value as of the
effective date of the merger to be substantially equivalent to $22.57 per share.
The merger is conditioned on, among other requirements,  approval by PSA's board
of directors,  receipt of a satisfactory fairness opinion by PSZ and approval by
the  shareholders  of PSZ. It is expected that any merger would close during the
first half of 1998.
