             [Published March 31, 2000 in Investors Business Daily]

This  announcement  is neither an offer to buy nor a solicitation of an offer to
sell  Units.  The Offer is being  made  solely by the formal  Offer to  Purchase
forwarded to Unitholders of record and is not being made to, nor will tenders be
accepted from or on behalf of, Unitholders residing in any jurisdiction in which
making or accepting the Offer would violate that  jurisdiction's  laws. In those
jurisdictions where the securities,  blue sky or other laws require the Offer to
be made by a licensed broker or dealer,  the Offer shall be deemed to be made on
behalf of Purchaser only by one or more  registered  dealers  licensed under the
laws of such jurisdiction.

                               (the "Purchasers")

The  Purchasers  are  offering to purchase for cash up to 5,542 Units of Limited
Partnership  Interest  of  Winthrop  California  Investors  Limited  Partnership
("Units")  at $285 per Unit upon the terms and  subject  to the  conditions  set
forth in Purchasers'  Offer to Purchase and in the related Letter of Transmittal
(which together constitute the "Offer" and the "Tender Offer Documents").
             THE OFFER AND WITHDRAWAL  RIGHTS EXPIRE AT 12:00 MIDNIGHT,  PACIFIC
             DAYLIGHT TIME, ON MAY 5, 2000, UNLESS THE OFFER IS EXTENDED.

     Funding for the purchase of the Units will be provided  through the capital
commitments of the Purchasers.  The Offer will expire at 12:00 midnight, Pacific
Standard  Time on May 5,  2000,  unless  and  until  Purchasers,  in their  sole
discretion,  shall have  extended the period of time for which the Offer is open
(such date and time, as extended the  "Expiration  Date").  If Purchasers make a
material change in the terms of the Offer, or if it waives a material  condition
to the Offer, Purchasers will extend the Offer and disseminate additional tender
offer  materials to the extent required by Rules 14d-4(c) and 14d-6(d) under the
Securities  Exchange Act of 1934, as amended (the "Exchange  Act").  The minimum
period during which an offer must remain open  following any material  change in
the terms of the Offer,  other than a change in price or a change in  percentage
of  securities  sought or a change in any dealer's  soliciting  fee, will depend
upon the facts and  circumstances  including the  materiality of the change with
respect to a change in price or, subject to certain limitations, a change in the
percentage of securities  sought or a change in any dealer's  soliciting  fee. A
minimum of ten business days from the date of such change is generally  required
to allow for adequate dissemination to Unitholders. Accordingly, if prior to the
Expiration  Date,  Purchasers  increase (other than  increases of not  more than
two percent of the  outstanding  Units) or  decreases  the number of Units being

                                        1





sought,  or increases or decreases  the  consideration  offered  pursuant to the
Offer,  and if the Offer is  scheduled  to expire at any time  earlier  than the
period  ending  on the  tenth  business  day from the date  that  notice of such
increase or decrease is first published, sent or given to Unitholders, the Offer
will be extended at least until the  expiration of such ten business  days.  For
purposes  of the Offer,  a  "business  day" means any day other than a Saturday,
Sunday or  federal  holiday  and  consists  of the time  period  from 12:01 a.m.
through  12:00  midnight,  Pacific  Standard  Time. In all cases payment for the
Units purchased  pursuant to the Offer will be made only after timely receipt of
the Letters of Transmittal (or facsimiles thereof),  properly completed and duly
executed,  with any  required  signature  guarantees,  and any  other  documents
required by such Letters of Transmittal.

     Tenders of Units made  pursuant to the Offer are  irrevocable,  except that
Unitholders  who tender their Units in response to the Offer will have the right
to withdraw their  tendered  Units at any time prior to the  Expiration  Date by
sending a written or facsimile  transmission  notice of withdrawal to Purchasers
specifying  the name of the person who  tendered the Units to be  withdrawn.  In
addition, tendered Units may be withdrawn at any time on or after June 30, 2000,
unless the tender has  theretofore  been accepted for payment as provided above.
If tendering  Unitholders  tender more than the number of Units that  Purchasers
seek to purchase  pursuant to the Offer,  Purchasers  will take into account the
number  of Units so  tendered  and take up and pay for as  nearly  as may be pro
rata, disregarding fractions,  according to the number of Units tendered by each
tendering  Unitholder during the period during which the Offer remains open. The
terms of the Offer are more fully set forth in the formal Tender Offer Documents
which are available from Purchasers. The Offer contains terms and conditions and
the information required by Rule  14d-6(e)(1)(vii)  under the Exchange Act which
are incorporated herein by reference.

     The Tender Offer Documents  contain  important  information which should be
read carefully before any decision is made with respect to the Offer. The Tender
Offer Documents may be obtained by written request to Purchasers or as set forth
below.  A request  has been made to the issuer  pursuant to Rule 14d-5 under the
Exchange  Act for  the  use of its  list of  Unit  holders  for the  purpose  of
disseminating the Offer to Unit holders. Upon compliance by the issuer with such
request,  the Tender Offer Documents and, if required,  other relevant materials
will be  mailed  to  record  holders  of  Units or  persons  who are  listed  as
participants in a clearing agency's  security  position listing,  for subsequent
transmittal to beneficial owners of Units.
