                         TWELFTH AMENDMENT TO THE THIRD
                        AMENDED AND RESTATED AGREEMENT OF
                  LIMITED PARTNERSHIP OF AIMCO PROPERTIES, L.P.

         This TWELFTH AMENDMENT TO THE THIRD AMENDED AND RESTATED AGREEMENT OF
LIMITED PARTNERSHIP OF AIMCO PROPERTIES, L.P., dated as of April 19, 2000 (this
"Amendment"), is being executed by AIMCO-GP, Inc., a Delaware corporation (the
"General Partner"), as the general partner of AIMCO Properties, L.P., a Delaware
limited partnership (the "Partnership"), pursuant to the authority conferred on
the General Partner by the Third Amended and Restated Agreement of Limited
Partnership of AIMCO Properties, L.P., dated as of July 29, 1994 (the
"Agreement"). Capitalized terms used, but not otherwise defined herein, shall
have the respective meanings ascribed thereto in the Agreement.

         WHEREAS, pursuant to Exhibit K of the Agreement, the Partnership Unit
Designation of the Class I High Performance Partnership Units of AIMCO
Properties, L.P. ("Partnership Unit Designation"), the General Partner
determined the designations, preferences and relative, participating, optional
or other special rights, powers and duties of the Class I High Performance
Partnership Units;

         WHEREAS, the General Partner and the holders of the outstanding Class I
High Performance Partnership Units wish to (i) clarify an ambiguity in the
definition of "AIMCO Total Return" in the Partnership Unit Designation, and (ii)
prevent the possibility of market manipulation distorting the calculation of
"Excess Return," as defined in the Partnership Unit Designation; and

         WHEREAS, the holders of all of the outstanding Class I High Performance
Partnership Units have consented to this amendment to the Agreement.

         NOW, THEREFORE, in consideration of the foregoing, and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

         1. The definition of "AIMCO Total Return" in Section 2 of the
Partnership Unit Designation is hereby amended to read in its entirety as
follows:

              "AIMCO Total Return" shall mean the Total Return of the REIT
         Shares for the Measurement Period; provided, however, that, for
         purposes of calculating the security price of the REIT Shares at the
         end of the Measurement Period, such price shall be the average of the
         daily market prices for twenty (20) consecutive

<PAGE>   2

         trading days ending immediately prior to the Class I High Performance
         Valuation Date. The market price for any such trading day shall be:

                    (i) if the REIT Shares are listed or admitted to trading on
               any securities exchange or The Nasdaq Stock Market's National
               Market System, the volume-weighted average of trading prices on
               such day, as reported by Bloomberg Financial Markets (or another
               reliable source selected by the General Partner), or if no trade
               takes place on such day, the average of the closing bid and asked
               prices on such day, as reported in the principal consolidated
               transaction reporting system;

                    (ii) if the REIT Shares are not listed or admitted to
               trading on any securities exchange or The Nasdaq Stock Market's
               National Market System, the last reported sale price on such day
               or, if no sale takes place on such day, the average of the
               closing bid and asked prices on such day, as reported by a
               reliable quotation source designated by the General Partner; or

                    (iii) if the REIT Shares are not listed or admitted to
               trading on any securities exchange or The Nasdaq Stock Market's
               National Market System and no such last reported sale price or
               closing bid and asked prices are available, the average of the
               reported high bid and low asked prices on such day, as reported
               by a reliable quotation source designated by the General Partner,
               or if there shall be no bid and asked prices on such day, the
               average of the high bid and low asked prices, as so reported, on
               the most recent day (not more than ten (10) days prior to the
               date in question) for which prices have been so reported;

         provided, however, that, if there are no bid and asked prices reported
         during the ten (10) days prior to the date in question, the market
         price of the REIT Shares shall be determined by the General Partner
         acting in good faith on the basis of such quotations and other
         information as it considers, in its reasonable judgment, appropriate.

         2. Except as specifically amended hereby, the terms, covenants,
provisions and conditions of the Agreement and the Partnership Unit Designation
shall remain unmodified and continue in full force and effect and, except as
amended hereby, all of the terms, covenants, provisions and conditions of the
Agreement are hereby ratified and confirmed in all respects.

                                    RECITAL

         WHEREAS, Borrower and Administrative Agent desire to amend the Credit
Agreement to increase the Combined Commitments by $5,000,000 to an aggregate

         WHEREAS, each of the Lenders has acknowledged and agreed that its

         WHEREAS, U.S. Bank, Administrative Agent and Borrower hereby consent
to the increase in the Commitments of U.S. Bank from $40,000,000 to

covenants contained herein, the parties agree as follows:

such Guarantor Subsidiary is not required by the terms of the Credit Agreement
or any other Loan Document to consent to the amendments to the Credit Agreement
effected pursuant to this Amendment and (ii) nothing in the Credit Agreement,
this Amendment or any other Loan Document shall be deemed to require the
consent of such Guarantor Subsidiary to any future amendments to the Credit
Agreement.
