                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.       GENERAL

         The accompanying consolidated financial statements, footnotes and
         discussions should be read in conjunction with the consolidated
         financial statements, related footnotes and discussions contained in
         the Registrant's Annual Report on Form 10-KSB for the year ended
         December 31, 2003.

         The financial information contained herein is unaudited. In the opinion
         of management, all adjustments necessary for a fair presentation of
         such financial information have been included. All adjustments are of a
         normal recurring nature. The consolidated balance sheet at December 31,
         2003 was derived from audited financial statements at such date.

         The results of operations for the three months ended March 31, 2004 and
         2003 are not necessarily indicative of the results to be expected for
         the full year.

         Certain amounts from 2003 have been reclassified to conform to the 2004
         presentation.

2.       EQUITY INVESTMENT IN DEVELOPMENT PARTNERSHIP

         The Registrant owns a 25% Limited Partner's interest in Crow Winthrop
         Development Limited Partnership (the "Development Partnership"), which
         is accounted for under the equity method. At March 31, 2004, the
         historical cost basis of the Registrant's equity investment in the
         Development Partnership is $13,659,000. As described below, pursuant to
         a settlement agreement, the Registrant is entitled to receive a
         preference payment of $22,000,000 from any "Capital Transaction," as
         defined, in exchange for the Registrant surrendering its interest in
         the Development Partnership.

         In October 2003, the Registrant entered into a settlement agreement
         with Crow Irvine #2, a California limited partnership ("Crow") which
         holds a 75% interest in and is the general partner of the Development
         Partnership. The Registrant and Crow agreed to the dismissal of two
         lawsuits between them that were pending in the Superior Court of the
         State of California, County of Orange. In addition, the Registrant and
         Crow agreed to an amendment of their partnership agreement. As part of
         the amendment, the Registrant is entitled to receive a preference
         payment of $22,000,000 arising from any "Capital Transaction," as
         defined, that occurs during the period October 3, 2003 through October
         2, 2005. If a Capital Transaction does not occur by October 3, 2005, in
         addition to the preference payment, the Registrant will then be
         entitled to receive interest of 6.0% per annum on the preference
         payment. If a Capital Transaction does not occur by October 3, 2008,
         the Registrant will become the general partner of the Development
         Partnership and Crow will become the limited partner of the Development
         Partnership. If the Registrant receives the preference payment and, if
         applicable, any accrued interest, the Registrant has agreed to
         surrender its interest in the Development Partnership to Crow.

                WINTHROP CALIFORNIA INVESTORS LIMITED PARTNERSHIP
                           FORM 10-QSB MARCH 31, 2004

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (CONTINUED)

2.       EQUITY INVESTMENT IN DEVELOPMENT PARTNERSHIP (CONTINUED)

         In March 2004, the Managing General Partner of the Registrant was
         advised by the general partner of the Development Partnership that the
         Development Partnership has entered into an agreement to sell a portion
         of the Development Partnership's land for a purchase price that, if the
         sale is consummated, would yield net proceeds sufficient to potentially
         pay a portion of or fully satisfy the $22,000,000 preference payment to
         the Registrant. The sale, however, is subject to the buyer's due
         diligence review as well as a number of other conditions. Accordingly,
         there can be no assurance that the sale will be consummated. If the
         sale is consummated, it is not expected that it will occur until
         December 2004 at the earliest. Further, prior to any sale being
         consummated, the Development Partnership will be required to build a
         parking garage at an estimated cost of $20,000,000 to ensure that
         sufficient parking is provided under applicable zoning laws and
         agreements.

3.       RELATED PARTY TRANSACTIONS

         Asset management fees earned by the Managing General Partner totaled
         $188,000 during the three months ended March 31, 2004 and March 31,
         2003.

         The Registrant paid the General Partners approximately $56,000 during
         the three months ended March 31, 2004 for distributions that should
         have been allocated to the General Partners in prior years.

4.       DISCONTINUED OPERATIONS

         The Registrant has classified the operations of its management
         partnership, Winthrop California Management Limited Partnership and its
         operating partnership, Crow Winthrop Operating Partnership as
         discontinued operations as a result of the sale of the Fluor
         Corporation World Headquarters Facility during 2002. Discontinued
         operations are summarized as follows:

                           FORM 10-QSB MARCH 31, 2004

ITEM 2.       MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

              The matters discussed in this Form 10-QSB contain certain
              forward-looking statements and involve risks and uncertainties
              (including changing market conditions, competitive and regulatory
              matters, etc.) detailed in the disclosures contained in this Form
              10-QSB and the other filings with the Securities and Exchange
              Commission made by the Registrant from time to time. The
              discussion of the Registrant's liquidity, capital resources and
              results of operations, including forward-looking statements
              pertaining to such matters, does not take into account the effects
              of any changes to the Registrant's operations. Accordingly, actual
              results could differ materially from those projected in the
              forward-looking statements as a result of a number of factors,
              including those identified herein.

              Liquidity and Capital Resources

              The Registrant uses its working capital reserves and any cash
              distributions received from Crow Winthrop Development Limited
              Partnership (the "Development Partnership") as its primary source
              of liquidity.

              In October 2003, the Registrant entered into a settlement
              agreement with Crow Irvine #2, a California limited partnership
              ("Crow") which holds a 75% interest in and is the general partner
              of the Development Partnership. The Registrant and Crow agreed to
              the dismissal of two lawsuits between them that were pending in
              the Superior Court of the State of California, County of Orange.
              In addition, the Registrant and Crow agreed to an amendment of
              their partnership agreement. As part of the amendment, the
              Registrant is entitled to receive a preference payment of
              $22,000,000 arising from any "Capital Transaction," as defined,
              that occurs during the period October 3, 2003 through October 2,
              2005. If a Capital Transaction does not occur by October 3, 2005,
              in addition to the preference payment, the Registrant will then be
              entitled to receive interest of 6.0% per annum on the preference
              payment. If a Capital Transaction does not occur by October 3,
              2008, the Registrant will become the general partner of the
              Development Partnership and Crow will become the limited partner
              of the Development Partnership. If the Registrant receives the
              preference payment and, if applicable, any accrued interest, the
              Registrant has agreed to surrender its interest in the Development
              Partnership to Crow.

              In March 2004, the Managing General Partner of the Registrant was
              advised by the general partner of the Development Partnership that
              the Development Partnership has entered into an agreement to sell
              a portion of the Development Partnership's land for a purchase
              price that, if the sale is consummated, would yield net proceeds
              sufficient to potentially pay a portion of or fully satisfy the
              $22,000,000 preference payment to the Registrant. The sale,
              however, is subject to the buyer's due diligence review as well as
              a number of other conditions. Accordingly, there can be no
              assurance that the sale will be consummated. If the sale is
              consummated, it is not expected that it will occur until December
              2004 at the earliest. Further, prior to any sale being
              consummated, the Development Partnership will be required to build
              a parking garage at an estimated cost of $20,000,000 to ensure
              that sufficient parking is provided under applicable zoning laws
              and agreements.

ITEM 2.       MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION
              (CONTINUED)

              Liquidity and Capital Resources (Continued)

              The Registrant had $1,949,000 in cash and cash equivalents at
              March 31, 2004. Cash and cash equivalents are temporarily invested
              in short-term instruments. The Registrant's level of liquidity
              based upon cash and cash equivalents experienced a $581,000
              decrease at March 31, 2004 as compared to December 31, 2003. The
              decrease resulted from $548,000 of net cash used in continuing
              operations and $56,000 of cash used in financing activities, which
              were partially offset by $23,000 of net cash provided by
              discontinued operations. Cash used in financing activities
              consisted of distributions to the General Partners for amounts
              that should have been allocated to them in prior years.

              In February 2004, Quadrangle Associates III LLC, an affiliate of
              Winthrop Financial Associates ("WFA"), a General Partner of the
              Registrant, offered to purchase up to 964 (27.54%) of the
              outstanding units of limited partnership interest of the
              Registrant for a purchase price of $2,450 per limited partnership
              interest upon the terms and subject to the conditions set forth in
              the affiliate's offer to purchase, as amended. The offer by
              Quadrangle Associates III LLC expired on March 31, 2004.
              Quadrangle Associates III LLC accepted a total of 160.25 (4.58%)
              of the outstanding units of limited partnership interest of the
              Registrant at the purchase price of $2,450 per unit. Pursuant to
              an agreement entered into with MB Special LLC, an entity
              affiliated with several original partners of WFA who retained an
              indirect minor interest in WFA and which has the right to review
              the Partnership's budget, distributions and extraordinary
              transactions, Mango Bay Realty LLC, an affiliate of MB Special
              LLC, has the right to acquire up to 46% of any units acquired by
              Quadrangle Associates III LLC in its offer, at any time prior to
              May 31, 2004.

              Results of Operations

              Net Loss

              The Registrant recorded a net loss of $210,000 for the three
              months ended March 31, 2004 as compared to a net loss of $374,000
              recorded in 2003. The decrease in net loss is primarily due to a
              decrease in equity in loss of the Development Partnership of
              $126,000 and a decrease in general and administrative expenses of
              $43,000.

              Income

              Interest income decreased by $4,000 during the three months ended
              March 31, 2004 as compared to 2003. This decrease is due to lower
              cash balances invested during the three months ended March 31,
              2004.

              Expenses

              Expenses decreased from $251,000 in 2003 to $208,000 in 2004,
              primarily as a result of decreased professional fees.

              Results of Operations (Continued)

              Equity in Loss of Development Partnership

              Equity in loss of the Development Partnership was $126,000 for the
              three months ended March 31, 2003 compared to no loss recorded for
              the three months ended March 31, 2004. As a result of the
              settlement agreement that is described above in Liquidity and
              Capital Resources, the Registrant has not recorded any additional
              losses on their equity investment in the Development Partnership
              due to the Registrant's historical cost basis being lower than the
              preference payment that the Registrant is entitled to receive in
              connection with the settlement agreement.

              Discontinued Operations

              The Registrant has classified the operations of its management
              partnership, Winthrop California Management Limited Partnership
              and its operating partnership, Crow Winthrop Operating Partnership
              as discontinued operations as a result of the sale of the Fluor
              Corporation World Headquarters Facility in 2002. Loss from
              discontinued operations was $5,000 for the three months ended
              March 31, 2003 compared to a loss of $6,000 for the three months
              ended March 31, 2004.

              Inflation

              Inflation is not expected to have a material impact on the
              operations or financial position of the Registrant.

              Critical Accounting Policy

              The Registrant's only significant critical accounting policy
              relates to the evaluation of the fair value of its equity
              investment. The Registrant assesses whether there has been a
              permanent impairment in the value of its equity investment if
              events or changes in circumstances indicate that the carrying
              amount of the equity investment may not be recoverable. The
              Registrant considers factors such as expected future operating
              income, trends and prospects, as well as the effects of demand,
              competition and other economic factors. The carrying amount would
              be adjusted, if necessary, to estimated fair value to reflect
              impairment in the value of the equity investment. The evaluation
              of the fair value of its equity investment is an estimate that is
              susceptible to change and actual results could differ from those
              estimates.

              None of the recently issued accounting standards had any effect on
              the Partnership's financial statements.

              Quantitative and Qualitative Disclosures of Market Risk

              The Registrant does not have any financial instruments that would
              expose it to market risk associated with the risk of loss arising
              from adverse changes in market rates and prices.
