          PURCHASE AND SALE AGREEMENT, dated December 5, 2000 between N'Tandem
Properties L.P., a Delaware limited Partnership (the "Buyer"), N'Tandem Trust,
an unincorporated California business trust and the sole general partner of the
Partnership ("N'Tandem"), and Windsor Park Properties 5, A California Limited
Partnership (the "Seller"), relating to the purchase by the Buyer from the
Seller of certain real property and ownership interests in real property, as
more particularly described herein.  The Buyer and the Seller hereby agree as
follows:

                                   ARTICLE I

                 PURCHASE OF PROPERTY AND OWNERSHIP INTERESTS

     1.1  Purchase of Property and Ownership Interests. At the Closing described
          --------------------------------------------
          in Paragraph 2.1, the Buyer will purchase the real properties owned in
          fee simple (the "Properties") and the ownership interests in real
          properties (the "Ownership Interests") described in Exhibit A hereto,
                                                              ---------
          and the Seller shall transfer the Properties and Ownership Interests
          to the Buyer free and clear of all liens (the "Sales").

     1.2  Purchase Price. The aggregate purchase price for the Properties and
          --------------
          the Ownership Interests is $9,017,000, which represents the aggregate
          appraised value of the Properties and the Ownership Interests less the
          aggregate discount applicable to the Ownership Interests, and is
          subject to the adjustments set forth in this Paragraph 1.2. (as so
          adjusted, the "Purchase Price"). To the extent that any Property, or
          any real property underlying any Ownership Interest (each, an
          "Underlying Property"), fails to be free and clear of all mortgage
          indebtedness and/or other liens, the Buyer shall receive at the
          Closing a credit against the Purchase Price (i) in the case of
          mortgage indebtedness and/or other liens encumbering any Property as
          of the closing date, in an amount equal to such mortgage indebtedness
          and/or other liens (or in the case of mortgage indebtedness and/or
          other liens relating to any Property encumbering more than one real
          property, in an amount equal to the product of the amount of such
          mortgage indebtedness and/or other liens times the ratio that the
          appraised value of such Property bears to the aggregate appraised
          values of all real properties encumbered by such mortgage indebtedness
          and/or other liens), and (ii) in the case of mortgage indebtedness
          and/or other liens encumbering any Underlying Property as of the
          closing date, in an amount equal to such mortgage indebtedness and/or
          other liens (or
<PAGE>

          in the case of mortgage indebtedness and/or other liens relating to an
          Underlying Property encumbering more than one real property, in an
          amount equal to the product of the amount of such mortgage
          indebtedness and/or other liens times the ratio that the appraised
          value of such Underlying Property bears to the aggregate appraised
          values of all real properties encumbered by such mortgage indebtedness
          and/or other liens) times the percentage ownership of such Underlying
          Property allocable or attributable to the Ownership Interest.

          ---------------------------
          to the Buyer (i) deeds of conveyance in proper form for recording
          relating to the Properties and the Town & Country Estates Ownership
          Interest, (ii) an Assignment Agreement, in form and substance
          satisfactory to the Buyer, assigning to the Buyer all of the Seller's
          right, title and interest in and to the Apache East, Denali Park
          Estates, Rancho Margate and Winter Haven Ownership Interests, and
          (iii) such other documents and instruments, and take such other
          action, as may be necessary or desirable to effect the transfer of the
          Properties and the Ownership Interests to the Buyer, in accordance
          with this Agreement.

     2.3  Buyer's Actions at Closing.  At the Closing, the Buyer will deliver to

          Seller at least 24 hours before the Closing, in an amount equal to the
          Purchase Price.

     2.4  Closing Costs.  With respect to the Properties and the Ownership
          -------------
          Interests, the Seller shall pay at the Closing such closing costs as
          are customarily paid by sellers of real property in Colorado. The
          Buyer shall be responsible for all other closing costs relating to the
          transfer of the Properties and the Ownership Interests payable at the
          Closing.
