Item 2.  Acquisition or Disposition of Assets

         On October 1, 1998, Apartment Investment and Management Company
("AIMCO") and Insignia Financial Group, Inc., a Delaware corporation
("Insignia"), completed the merger (the "Insignia Merger") of Insignia with and
into AIMCO pursuant to the Amended and Restated Agreement and Plan of Merger,
dated as of May 26, 1998, among AIMCO, AIMCO Properties, L.P., Insignia and
Insignia/ESG Holdings, Inc. (the "Insignia Merger Agreement"). Pursuant to the
Insignia Merger Agreement, on September 15, 1998, Insignia distributed to its
stockholders all assets related to its U.S. and international commercial real
estate business, its New York-based cooperative and condominium management
company, its single-family home brokerage operations and other related holding
(the "Spin Off").  Previously, on September 14, 1998, the stockholders of AIMCO
approved the Insignia Merger Agreement and the stockholders of Insignia approved
the Spin Off and the Insignia Merger Agreement. 

         In the Insignia Merger, each share of Class A Common Stock, par value
$.01 per share, of Insignia, was converted into the right to receive 0.262
shares of Class E Cumulative Convertible Preferred Stock, par value $.01 per
share, of AIMCO ("AIMCO Class E Preferred Stock"). AIMCO will issue up to a
total of approximately 8.96 million shares of AIMCO Class E Preferred Stock
pursuant to the Insignia Merger. In addition, AIMCO repaid approximately $325
million in outstanding indebtedness of Insignia, and assumed approximately $149
million aggregate principal amount of 6 1/2% Convertible Debentures originally
issued by Insignia.

         The terms of the AIMCO Class E Preferred Stock provide that in addition
to receiving the same dividends as holders of AIMCO Common Stock, holders of
AIMCO Class E Preferred Stock are entitled to a special cash dividend of $50.0
million in the aggregate, and when such dividend is paid, the AIMCO Class E
Preferred Stock automatically will convert into AIMCO Common Stock on a
one-for-one basis, subject to antidilution adjustments, if any.

         In October 1998, the AIMCO Operating Partnership and AIMCO, entered 
into a $300 million senior unsecured interim term loan agreement with an
affiliate of Lehman Brothers Inc. The term loan matures in one year. AIMCO used
the proceeds to refinance existing indebtedness outstanding of Insignia at the
time of merger.

         Also in connection with the Insignia Merger, AIMCO amended and
restated its revolving credit facility with Bank of America National Trust and 
Savings Association and BankBoston, N.A. (the "Credit Facility"). The Credit 
Facility now provides for loans of up to $100 million, including a $30 million 
swing-line. AIMCO Properties, L.P. is the borrower under the Credit Facility, 
and all obligations thereunder are guaranteed by AIMCO and certain of its 
subsidiaries.

         As a result of the Insignia Merger, as of October 1, 1998, AIMCO owned 
or controlled 58,495 units in 209 apartment properties, held an equity interest 
in 239,879 units in 1,335 apartment properties and managed 97,716 units in 759 
apartment properties for third party owners and affiliates. AIMCO's press 
release dated October 2, 1998, relating to the Insignia Merger is included as 
Exhibit 99.1 to this Report and is incorporated herein by reference.

ITEM 5.  OTHER EVENTS.

         As a result of the Insignia Merger, AIMCO acquired approximately 51% of
the common shares of beneficial interest, par value $.01 per share ("IPT
Shares"), of Insignia Properties Trust, a Maryland real estate investment trust
("IPT"). On October 2 1998, AIMCO and IPT executed a definitive merger agreement
(the "IPT Merger Agreement") pursuant to which IPT will be merged into AIMCO or
a subsidiary of AIMCO, and IPT shareholders will receive $13.25 per share in
cash or AIMCO common stock worth $13.28 per share, at AIMCO's option. The
transactions contemplated by the IPT Merger Agreement are subject to certain
conditions. The IPT merger requires the approval of a majority of the
outstanding IPT shares. AIMCO intends to vote all of its IPT shares in favor of
the IPT merger. AIMCO's press release dated October 5, 1998, relating to the IPT
Merger Agreement is included as Exhibit 99.2 to this Report and is incorporated
herein by reference.

such merger within three months following the effective time of the Insignia
Merger, and the performance of AIMCO's obligations under this Agreement, if it
uses its reasonable best efforts to consummate the Merger (as hereinafter
defined) within such period, will constitute AIMCO's performance of such
obligations under the IFG Agreement;

                  WHEREAS, pursuant to an Agreement and Plan of Merger, dated as
of July 18, 1997, by and among Angeles Mortgage Investment Trust, an

                  WHEREAS, the surviving entity in the Merger intends that,
following the Merger, it shall continue to be subject to taxation as a real
estate investment trust (a "REIT") within the meaning of the Internal Revenue
Code of 1986, as amended (the "Code").

                  NOW, THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements contained herein, the
parties hereto, intending to be legally bound hereby, agree as follows:


                                    ARTICLE I

                                   THE MERGER

                  (a) At least 14 business days prior to the anticipated mailing
of the Information Statement/Prospectus (as defined in Section 6.2) AIMCO shall
notify IPT whether, at the Effective Time (as defined in Section 1.4) (x) IPT
shall be merged with and into AIMCO, with AIMCO being the surviving entity or
(y) a subsidiary of AIMCO shall be merged with and into IPT, with IPT being the
surviving entity. If AIMCO elects to cause the Merger to occur pursuant to (y)
above, then this Agreement shall be amended to (i) add such subsidiary as a
party to this Agreement, (ii) make such other additional incidental amendments
as are needed to provide for a subsidiary merger, and where required, to provide
that AIMCO will cause its subsidiary to take action in lieu of AIMCO, as agreed
by IPT and AIMCO and their respective counsel, and (iii) include an
unconditional guarantee by AIMCO of the obligations of its subsidiary in the
Merger.

                  (b) In the event AIMCO shall have been advised by its tax
counsel that it does not expect to be able to issue the opinion referred to in
Section 7.2(f) of this Agreement at the Closing, in addition to the actions
referenced to in the second sentence of this Section 1.1, IPT, acting through a
majority of the Continuing Trustees, and AIMCO shall use their best efforts to
restructure the form of the transaction to provide for the issuance of AIMCO
Common Stock without materially changing either the consideration to be received
by IPT Shareholders or the tax or other economic consequences of the transaction
to AIMCO and its Subsidiaries, but if the transaction cannot reasonably be so
restructured, it shall be restructured as an all cash transaction.

                  Section 1.2 The Merger.  Upon the terms and subject to the 
conditions of this Agreement, at the Effective Time IPT shall be merged with and
into AIMCO in accordance with the laws of the State of Maryland. AIMCO shall be
the surviving entity

efforts to consummate the Merger as soon as possible.

immediately prior to the Effective Time shall be the directors and officers,
respectively, of the Surviving Entity until their respective successors are duly
elected and qualified. Subject to the foregoing, the additional effects of the
Merger shall be as provided in Section 3-114 of the Maryland General Corporation
Law ("MGCL") and Section 8-501.1(n) of Title 8 of the Corporations and
Associations Article of the Annotated Code of Maryland (the "MCAA").

                  Section 1.4 Effective Time of the Merger. On the Closing Date

AIMCO and IPT with the State Department of Assessments and Taxation of the State
of Maryland pursuant to the MGCL and the MCAA. The Merger shall become effective
upon the acceptance of the articles of merger for record by the State Department

                  (c) Cancellation of Certain IPT Shares. As of the Effective
Time, by virtue of the Merger and without any action on the part of any IPT
Shareholder, all IPT Shares owned directly or indirectly by AIMCO and its
Subsidiaries shall automatically be canceled and retired and shall cease to
exist, and no Merger Consideration or other consideration shall be issued or
delivered in exchange therefor.

                  (d)      Restricted Shares.

                           (i) Treatment. At the Effective Time, each unvested
         restricted IPT Share awarded under the IPT 1997 Share Incentive Plan
         (the "IPT Share Plan") shall, by virtue of this Agreement and without
         any further action of IPT, AIMCO or the holder of such restricted
         share, be converted into that number of restricted shares ("AIMCO
         Restricted Shares") of AIMCO Common Stock equal to the Conversion
         Ratio. Each such AIMCO Restricted Share shall continue to have, and be
         subject to, the same terms and conditions (including rights to Dividend
         Equivalents (as defined in the IPT Share Plan), if any) set forth in
         the IPT Share Plan and the applicable restricted share agreement, each
         as in effect immediately prior to the Effective Time.

                           (ii) Registration. AIMCO shall (A) cause such shares
         of AIMCO Common Stock to be covered by an effective registration
         statement on Form S-8 (or any successor or other appropriate forms),
         and (B) use its reasonable best efforts to maintain the effectiveness
         of such registration statement (and maintain the current status of the
         prospectus contained therein) for so long as the restricted shares
         remain outstanding.

                  (e) Cash Election Option. Not later than the close of business
on the second NYSE trading day immediately preceding the first day of the AIMCO
Reference Period, AIMCO shall deliver to IPT a written notice (the "Cash
Election Notice"), which shall be irrevocable, in which AIMCO specifies a
percentage, from 0% to 100%, of the Merger Consideration to be paid in cash (the
"Cash Percentage"); provided, however, that if (x) AIMCO fails to timely deliver
the Cash Election Notice to IPT or (y) the IPT Meeting Date is on or after March
1, 1999, then AIMCO shall not be entitled to deliver a Cash Election Notice
(i.e., the Cash Percentage shall be deemed to be zero percent (0%) and AIMCO
shall not be entitled to pay any portion of the Merger Consideration in cash).
AIMCO shall use its best efforts to cause IPT to issue, on the date the Cash
Election Notice is required to be delivered, via the Dow Jones News Service and
PR Newswire, a press release announcing the Cash Percentage.

                  Section 2.2 Surrender of Certificates.

                  (a) AIMCO shall provide on the date of the Effective Time to
the paying agent selected by AIMCO (the "Paying Agent") certificates
representing shares of AIMCO Common Stock and funds as necessary to make
issuances and payments pursuant to Sections 2.l(b) and 2.4 (such certificates
and funds being hereinafter referred to as the "Exchange Fund"). Out of the
Exchange Fund, the Paying Agent shall make, pursuant to irrevocable
instructions, the issuances and payments referred to in Sections 2.1(b) and 2.4,
and the Exchange Fund shall not be used for any other purpose. The Paying Agent
may invest portions of the Exchange Fund as AIMCO may direct, provided that such
investments be in obligations of, or guaranteed by, the United States of
America, in commercial paper obligations receiving the highest rating from
either Moody's Investors Service or Standard & Poor's Corporation or in
certificates of deposit, bank repurchase agreements or bankers' acceptances of
commercial banks with capital exceeding $100,000,000. Any net profit resulting
from, or interest or income produced by, such investments shall be payable to
AIMCO. AIMCO shall replace any monies lost through any investment made pursuant
to this Section 2.2(a) upon request therefor by the Paying Agent. Any portion of
the Exchange Fund that remains unclaimed after 180 days after the Effective Time
shall be returned to AIMCO upon its request made to the Paying Agent, after
which time the holder of any unsurrendered Certificates shall look only to AIMCO
for delivery of the Merger Consideration. AIMCO shall not be liable to any
Person for any funds delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

                  (b) As soon as practicable after the Effective Time, AIMCO
shall cause the Paying Agent to mail to each holder of record of a Certificate
which immediately prior to the Effective Time represented an IPT Share that was
canceled and became instead the right to receive Merger Consideration pursuant
to Section 2.1(b): (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon actual delivery of the Certificates to the Paying Agent); and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for the Merger Consideration. Upon surrender of a Certificate to the
Paying Agent for exchange (or to such other agent or agents as may be appointed
by AIMCO), together with a duly executed letter of transmittal and such other
documents as the Paying Agent shall require, the holder of such Certificate
shall be entitled to receive, in respect of the IPT Shares formerly represented
thereby, (A) a certificate or certificates representing that number of whole
shares of AIMCO Common Stock which such holder has the right to receive pursuant
to the provisions of Section 2.1(b), if any, (B) the amount of cash which such
holder has the right to receive pursuant to the provisions of Section 2.1(b) and
(C) cash in lieu of fractional shares which such holder is entitled to receive
pursuant to Section 2.4. If payment is to be made to a Person other than the one


                                        8

<PAGE>   10



in whose name a surrendered Certificate is registered, it shall be a condition
of receipt of the Merger Consideration that the Certificate so surrendered be
properly endorsed or otherwise in proper form for transfer and that the Person
requesting such payment either pay any transfer or other taxes required by
reason of the payment to a Person other than the registered holder of the
Certificate surrendered or establish to the satisfaction of the Surviving Entity
that such tax has been paid or is not applicable. Until surrendered in
accordance with the provisions of this Section 2.2, after the Effective Time
each Certificate shall represent for all purposes only the right to receive the
Merger Consideration for each IPT Share represented by such Certificate,
together with any dividends and other distributions paid in respect thereof
after the Effective Time.

                  Section 2.3 Closing of Transfer Books; Etc. From and after the
Effective Time, the share transfer books of IPT shall be closed, and no
registration of any transfer of any IPT Shares shall thereafter be made on the
records of IPT. If, after the Effective Time, Certificates are presented to
AIMCO for any reason, they shall be canceled, and each IPT Share represented
thereby shall be exchanged for the Merger Consideration, together with any
dividends and other distributions paid in respect thereof after the Effective
Time. Shares of AIMCO Common Stock issued in the Merger shall be issued as of,
and be deemed to be outstanding as of, the Effective Time. AIMCO shall cause all
such shares of AIMCO Common Stock issued pursuant to the Merger to be duly
authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights. In the event any Certificate(s) shall have been lost, stolen
or destroyed, upon the making of any affidavit of that fact by the IPT
Shareholder claiming such Certificate(s) to be lost, stolen or destroyed and, if
reasonably required by AIMCO or the Paying Agent, upon the posting by such IPT
Shareholder of a bond in such amount as reasonably determined as indemnity
against any claim that may be made against either of them with respect to such
Certificate(s), the Paying Agent shall issue the Merger Consideration in respect
of each IPT Share represented by such lost, stolen or destroyed Certificate(s).
Appropriate procedures shall be established by AIMCO and the Paying Agent so
that each holder of a Certificate at the Effective Time shall be entitled to
vote on all matters subject to the vote of holders of AIMCO Common Stock with a
record date on or after the date of the Effective Time, whether or not such
Certificate holder shall have surrendered Certificates in accordance with the
provisions of this Agreement. For purposes of the immediately preceding
sentence, AIMCO may rely conclusively on the shareholder records of IPT in
determining the identity of, and the number of IPT Shares held by, each holder
of a Certificate at the Effective Time.

                  Section 2.4 Fractional Shares. Notwithstanding any other
provision of this Agreement, no fractional shares of AIMCO Common Stock will be
issued, and any IPT Shareholder entitled to receive a fractional share of AIMCO
Common Stock but for this Section 2.4 will be entitled to receive a cash payment
in lieu thereof equal to such


                                        9

<PAGE>   11



shareholder's proportionate interest in a share of AIMCO Common Stock multiplied
by the AIMCO Reference Price as of the Effective Time.

                  Section 2.5 No Other Rights. Upon consummation of the Merger,
the holder of a Certificate at and after the Effective Time shall have no rights
under this Agreement with respect to the IPT Shares represented thereby other
than the right to receive the Merger Consideration together with any dividends
and other distributions paid in respect thereof after the Effective Time, upon
the surrender of such Certificate pursuant to Section 2.2 and the right to
receive any declared but unpaid distributions in respect of such IPT Shares.
Nothing in this Agreement supersedes the right of the IPT Shareholders to
enforce Section 5.6 for the period provided in Section 9.1.


                                   ARTICLE III

are again so satisfied or waived, subject, however, to Article VIII hereof, or

mutually agree (the "Closing Date").

1934, as amended (the "Exchange Act"), and the rules of the NYSE (the "AIMCO
Required Filings"), no declaration, filing or registration with, or notice to,
or authorization, consent or approval of, any court, federal, state, local or
foreign government or regulatory body (including the United States Department of
Housing and Urban Development and/or applicable state housing agencies
(collectively, "HUD"), a stock exchange or other self-regulatory body) or
authority (each, a "Governmental Authority") is necessary for the execution and
delivery of this Agreement by AIMCO or the consummation by AIMCO of the
transactions contemplated hereby, except as would not result, individually or in
the aggregate, in an AIMCO Material Adverse Effect.

                  Section 5.4 Reports and Financial Statements. All filings
required to be made by AIMCO since December 31, 1997 under Section 13(a), 13(c),
14 or 15(d) of the Exchange Act have been filed with the Securities and Exchange
Commission ( the "SEC") (the "AIMCO SEC Reports"). The AIMCO SEC Reports, as of
their respective dates, complied in all material respects with all applicable
requirements of the appropriate statutes and the rules and regulations
thereunder. As of their respective dates, the AIMCO SEC Reports did not contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the


                                       15

<PAGE>   17



statements therein, in light of the circumstances under which they were made,
not misleading. The audited consolidated financial statements and unaudited
interim financial statements of AIMCO included in the AIMCO SEC Reports have
been prepared in accordance with generally accepted accounting principles
("GAAP") applied on a consistent basis (except as may be indicated therein or in
the notes thereto or, with respect to unaudited interim financial statements, as
permitted by Form 10-Q of the SEC) and fairly present, in all material respects,
the financial position of AIMCO as of the dates thereof and the results of its
operations and cash flows for the periods then ended, subject, in the case of
the unaudited interim financial statements, to normal, recurring audit and
year-end adjustments.

                  Section 5.5 Absence of Certain Changes or Events. Except as
set forth in the AIMCO SEC Reports, since December 31, 1997, each of AIMCO and
its Subsidiaries has conducted its business in the ordinary course of business
consistent with past practice, and there has not been any AIMCO Material Adverse
Effect.

                  Section 5.6 Registration Statement, Information
Statement/Prospectus and Schedule 13E-3. The information supplied or to be
supplied by or on behalf of AIMCO for inclusion or incorporation by reference in
(a) the Registration Statement (as defined in Section 6.2), at the time it is
filed with the SEC, at the time it becomes effective under the Securities Act
and at the Effective Time, (b) the Information Statement/Prospectus (as defined
in Section 6.2), at the time it is filed with the SEC, at the time it is mailed
to the IPT Shareholders and at the time of the IPT Meeting and (c) the Schedule
13E-3 (as defined in Section 6.2), at the time such statement is filed with the
SEC, will not contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they are made,
not misleading. The Registration Statement, the Information Statement/Prospectus
and the Schedule 13E-3 will comply as to form in all material respects with the
provisions of the Securities Act and the Exchange Act and the rules and
regulations thereunder.

                  Section 5.7 No Vote Required. The approval of this Agreement,
the Merger and the other transactions contemplated hereby, including without
limitation, the issuance and listing on the NYSE of the AIMCO Common Stock to be
issued in the Merger, does not require the vote of the holders of any class or
series of the capital stock of AIMCO or any of its Subsidiaries.

                  Section 5.8 Tax Matters.

                  (a) Filing of Timely Tax Returns. AIMCO and each of its
Subsidiaries have filed (or there has been filed on its behalf) all Tax Returns
required to be filed by


                                       16

<PAGE>   18



each of them under applicable law. All such Tax Returns were and are in all
material respects true, complete and correct and filed on a timely basis.

                  (b) Payment of Taxes. AIMCO and each of its Subsidiaries have,
within the time and in the manner prescribed by law, paid all Taxes that are
currently due and payable for all periods through and including the Closing
Date, except for those contested in good faith and for which adequate reserves
have been taken.

                  (c) Tax Reserves. AIMCO and its Subsidiaries have established
on their books and records reserves adequate to pay all material Taxes and
reserves for deferred income Taxes in accordance with GAAP.

                  (d) Tax Liens. There are no Tax liens upon the material assets
of AIMCO or any of its Subsidiaries except liens for Taxes not yet delinquent.

                  (e) REIT Classification. At all times since the initial public
offering of AIMCO, AIMCO has been organized and operated in conformity with the
Status Requirements, and its proposed method of operation will enable it to
continue to meet the Status Requirements and otherwise qualify as a REIT.

                  (f) Continuation as REIT. The consummation by AIMCO of the
transactions contemplated hereby or compliance with or fulfillment of terms and
provisions hereof by AIMCO, will not adversely affect the qualification of AIMCO
as a REIT for each taxable year ending on or after the Closing Date.

                  (g) Deficiencies. No deficiencies for any Taxes have been
proposed, asserted or assessed against AIMCO and there is no outstanding waiver
of the statute of limitations with respect to any Taxes or Tax Returns of AIMCO.

                  (h) Domestic Control. AIMCO believes that it is a
"domestically-controlled" REIT within the meaning of Section 897(h)(4)(B) of
the Code.

                  Section 5.9 Brokers. No broker, finder or investment banker is
entitled to any broker's, finder's or other fee or commission in connection with
the Merger or the transactions contemplated by this Agreement based upon
arrangements made by or on behalf of AIMCO.

                  Section 5.10 Absence of Inducement. In entering into this
Agreement, AIMCO has not been induced by, or relied upon, any representations,
warranties, or statements by IPT not set forth or referred to in this Agreement
or the other documents required to be delivered hereby, whether or not such
representations, warranties, or


                                       17

<PAGE>   19



statements have actually been made, in writing or orally, and AIMCO acknowledges
that, in entering into this Agreement, IPT has been induced by and relied upon
the representations and warranties of AIMCO herein set forth, the information
set forth in the AIMCO SEC Reports and in the other documents required to be
delivered hereby. AIMCO has made its own investigation of IPT prior to the
execution of this Agreement and has not been induced by or relied upon any
representations, warranties or statements as to the advisability of entering
into this Agreement other than as set forth above.

                                   ARTICLE VI

                              ADDITIONAL AGREEMENTS

                  Section 6.1 IPT and IPLP Distributions.

                  (a) IPT shall (and shall cause IPLP to) continue to make
regular quarterly distributions, as follows: IPT shall pay on October 15, 1998
its previously declared distribution of $.16 per IPT Share to IPT Shareholders
of record on September 30, 1998; thereafter, IPT shall declare and pay quarterly
distributions with record dates and payment dates which are exactly the same as
the record dates and payment dates for regular quarterly distributions paid by
AIMCO in respect of the AIMCO Common Stock, in each case at the then current IPT
Distribution Amount (determined as of the applicable record date); provided,
however, that with respect to the first such IPT distribution required to be
declared and paid after October 15, 1998, the per-IPT Share amount of such
distribution shall be an amount equal to the otherwise applicable IPT
Distribution Amount, multiplied by the number of days that have elapsed from and
including December 23, 1998 through and including the record date for such
distribution, divided by 91 (rounded up to the next whole cent).

                  (b) In the event that the Effective Time has not occurred on
or before February 28, 1999, if at any time thereafter AIMCO declares any
distribution on the AIMCO Common Stock other than a regular quarterly
distribution, with a record date for such distribution which is a date prior to
the date of the Effective Time (a "Special AIMCO Distribution"), then IPT shall
promptly declare and pay a corresponding distribution in an amount equal to the
amount of such Special AIMCO Distribution, multiplied by the IPT Exchange Value,
divided by the AIMCO Collar Price.

                  (c) If and to the extent that IPT reasonably determines that
the distributions paid by IPT pursuant to the foregoing subsections (a) and (b)
of this Section 6.1 are not sufficient for IPT to meet the distribution
requirements applicable to REITs for its taxable year ended on the Closing Date,
including as a result of the AMIT Merger, then IPT shall, prior to the Effective
Time, pay one or more special distributions, in


                                       18

<PAGE>   20



respect of the IPT Shares in an aggregate amount equal to amount of such
shortfall (the per-IPT Share aggregate amount of such distributions, if any, is
referred to herein as the "Excess Distribution Amount").

                  (d) AIMCO covenants and agrees that AIMCO will use its best
efforts to cause IPT to timely declare and pay the distributions it is required
to make pursuant to the foregoing subsections (a), (b) and (c) of this Section
6.1.

                  Section 6.2 Registration Statement, Information
Statement/Prospectus and Schedule 13E-3. As soon as reasonably practicable after
the date hereof (a) AIMCO shall prepare and file with the SEC a registration
statement (as amended, the "Registration Statement") in connection with the
issuance of AIMCO Common Stock pursuant to the Merger, in which the Information
Statement/Prospectus (as defined below) shall be included as a prospectus, and
(b) the parties shall prepare and file with the SEC a combined information
statement and prospectus to be distributed in connection with the Merger and the
transactions contemplated hereby (as amended, the "Information
Statement/Prospectus") and a transaction statement on Schedule 13E-3 (the
"Schedule 13E-3"). The parties shall use their reasonable best efforts to have
the Registration Statement declared effective under the Securities Act by the
SEC as soon as practicable after such filing and to cause the Information
Statement/Prospectus to be mailed to IPT Shareholders as soon as practicable
after the Registration Statement is declared effective by the SEC. Each party
shall furnish all information concerning itself which is required or customary
for inclusion in the Registration Statement, the Information
Statement/Prospectus or the Schedule 13E-3. The information provided by any
party for use in the Registration Statement, the Information
Statement/Prospectus or the Schedule 13E-3 shall be true and correct in all
material respects without omission of any material fact which is required to
make such information not false or misleading. No representation, covenant or
agreement is made by any party with respect to information supplied by the other
party for inclusion in the Registration Statement, the Information
Statement/Prospectus or the Schedule 13E-3. Each party shall also take such
action as may be reasonably required to cause the shares of AIMCO Common Stock
covered by the Registration Statement to be approved for listing on the NYSE as
of the Effective Time, upon official notice of issuance. Each party shall also
take such action as may be reasonably required to cause the shares of AIMCO
Common Stock issuable in connection with the Merger to be registered or to
obtain an exemption from registration under applicable state "blue sky" or
securities laws; provided, however, that no party shall be required to register
or qualify as a foreign corporation or to take other action which would subject
it to general service of process in any jurisdiction where the Surviving Entity
will not be, following the Merger, so subject.



                                       19

                  Section 6.3 Regulatory Matters. Each party shall cooperate and
use its reasonable best efforts to promptly prepare and file all necessary
documentation and to effect all necessary applications, notices, petitions,
filings and other documents, including, without limitation, the AIMCO Required
Filings.

                  Section 6.4 Shareholder Approval. IPT shall, as soon as
practicable after the date hereof, (a) take all steps necessary to duly call,
give notice of, convene and hold a meeting of the IPT Shareholders (an "IPT
Meeting") for the purpose of voting on the Merger, which meeting shall be held
on a date (the "IPT Meeting Date") which is a NYSE trading day, provided that
the day immediately preceding such date must also be a NYSE trading day, and (b)
distribute to IPT Shareholders the Information State ment/Prospectus. The IPT
Board, acting upon the recommendation of a majority of the Continuing Trustees
(as defined in the IPT Bylaws), unless otherwise required in accordance with its
fiduciary duties to IPT Shareholders, shall recommend to such shareholders the
approval of the Merger, this Agreement and the transactions contem plated hereby
and cooperate and consult with AIMCO with respect to each of the foregoing
matters. Notwithstanding the foregoing, IPT and the Continuing Trustees may take
and disclose to IPT Shareholders a position contemplated by Rule 14e-2
promulgated under the Exchange Act if required to do so by the Exchange Act,
comply with Rule 14d-9 thereunder and make all other disclosures required by
applicable law.

                  Section 6.5 Vote of IPT Shares Owned by AIMCO. AIMCO agrees to
vote all IPT Shares owned of record by it, and to cause all IPT Shares owned of
record by its Subsidiaries to be voted, for approval of this Agreement and the
transactions contemplated hereby and has executed a proxy in favor of Messrs.
Aston, Farkas and Garrison (the "Proxyholders") to vote all such IPT Shares held
by AIMCO, directly or indirectly, in favor of the Merger. AIMCO further agrees
that, through the Effective Time, it shall not (i) sell, transfer or otherwise
dispose of any IPT Shares owned by it or any of its Subsidiaries, (ii) cause or
permit IPT to issue additional IPT Shares to any other Person or take any other
action which could have the effect of reducing the proportion of IPT Shares
owned by AIMCO and its Subsidiaries that are entitled to vote on this Agreement
and the transactions contemplated hereby, or (iii) grant any proxies with
respect to such shares; provided, however, that AIMCO may (a) transfer IPT
Shares owned by it to its Subsidiaries so long as such Subsidiary agrees to be
bound by the terms of this Agreement and to execute a proxy to vote such IPT
Shares in favor of the Merger in the form attached as Exhibit 6.5 or (b) pledge
such IPT Shares to a commercial bank or other bona fide financial institution
with capital exceeding $100,000,000 (a "Financial Institution") so long as such
Financial Institution agrees in writing to (1) honor the proxy given by AIMCO to
the Proxyholders with respect to such pledged IPT Shares on the date hereof, (2)
execute a proxy in favor of the Proxyholders or their successors once the
Financial Institution obtains the right to vote such pledged IPT


                                       20

<PAGE>   22



Shares and (3) cause any transferee of such IPT Shares from the Financial
Institution to execute a proxy in favor of the Proxyholders or their successors
and to agree to cause any subsequent transferee of the IPT Shares to also agree
to the obligations in subsection (3).

                  Section 6.6 Public Announcements. Subject to each party's
disclosure obligations imposed by law and the rules of any national securities
exchange or inter-dealer quotation system on or in which the shares of stock,
beneficial interest or other ownership interests of IPT or AIMCO are now or may
later be listed or authorized to be quoted, IPT and AIMCO shall cooperate with
each other in the development and distribution of all news releases and other
public announcements with respect to this Agreement or any of the transactions
contemplated hereby and shall not issue any public announcement or statement
with respect hereto or thereto without the consent of the other party (which
consent shall not be unreasonably withheld).

                  Section 6.7 Expenses. All costs and expenses incurred in
connection with this Agreement and the transactions contemplated hereby shall be
paid by the party incurring such expenses.

                  Section 6.8 Further Assurances. Each party shall, and shall
cause its Subsidiaries to, execute such further documents and instruments and
take such further action, including, without limitation, obtaining any consents,
authorizations, exemptions and approvals, as may be necessary to perform the
obligations and satisfy the conditions to be performed or satisfied by either
party pursuant to this Agreement or as may reasonably be requested by the other
party in order to consummate the Merger in accordance with the terms hereof. In
addition, AIMCO agrees to use its commercially reasonable efforts to retain
counsel within 30 days from the date hereof to provide the form of opinion
required by Section 7.2(g).

                  Section 6.9 Transfer Taxes. The parties shall cooperate in the
preparation, execution and filing of all returns, questionnaires, applications
or other documents regarding the real property transfer or gains, sales, use,
transfer, value added, stock transfer and stamp taxes, any transfer, recording,
registration and other fees or similar Taxes ("Transfer Taxes") which become
payable in connection with the transactions contemplated by this Agreement that
are required to be filed on or before the Closing Date.

                  Section 6.10 IPT Trustees and Officers. No later than promptly
after the execution and delivery of this Agreement by both parties, IPT shall
(a) cause two members of the IPT Board to resign their trusteeships, (b)
increase the size of the IPT Board to eleven and cause each of the trustee
candidates designated by AIMCO listed on Schedule 6.10-1 hereto (together with
their successors, the "AIMCO-nominated


                                       21

<PAGE>   23



Trustees") to be elected as a trustee of IPT, (c) cause the officer candidates
designated by AIMCO and listed on Schedule 6.10-2 hereto to be appointed to the
respective positions indicated on such Schedule, (d) establish a committee of
the IPT Board, consisting solely of AIMCO-nominated Trustees, authorized and
empowered to act to the extent set forth in the IPT Bylaws, (e) recognize that
the Continuing Trustees (as defined in the IPT Bylaws) of the IPT Board,
consisting of Andrew L. Farkas, James A. Aston, Warren M. Eckstein, Frank M.
Garrison and Bryan L. Herrmann, are authorized and empowered to act to the
extent set forth in the IPT Bylaws, and (f) establish an executive committee of
the IPT Board, to consist solely of AIMCO-nominated Trustees listed on Schedule
6.10-3, to act to the extent set forth in the IPT Bylaws. The committees
referred to in the preceding sentence shall not be dissolved prior to the
Effective Time or the termination of this Agreement. The powers of the
Continuing Trustees shall not be modified prior to the Effective Time or the
termination of this Agreement without the consent of a majority of the
Continuing Trustees. If, after the date hereof and prior to the Effective Time,
any IPT Shareholder vote is taken for the election of a trustee to any position
on the IPT Board currently occupied by any of the Continuing Trustees or by
their successors duly elected hereunder, AIMCO shall vote its IPT Shares for the
reelection of each such Continuing Trustee or for the election of such
Continuing Trustee's successor designated by a majority of the Continuing
Trustees. If, after the date hereof and prior to the Effective Time, any vacancy
on the IPT Board arises with respect to a trustee position occupied by a
Continuing Trustee, AIMCO shall cause the AIMCO-nominated Trustees to vote to
fill such vacancy by electing a person nominated by a majority of the Continuing
Trustees. After the date hereof and prior to the earlier of the Effective Time
or the termination of this Agreement, without the prior written consent of a
majority of the Continuing Trustees, which shall not be unreasonably withheld,
IPT shall not terminate (x) its independent auditors, (y) Lehman Brothers Inc.
from serving as its financial advisor with respect to the Merger, or (z)
Proskauer Rose LLP, Miles & Stockbridge, Rogers & Wells or Akin, Gump, Strauss,
Hauer & Feld from serving as its legal counsel with respect to the Merger. The
parties agree that Jeffrey P. Cohen shall remain as Secretary of the Company,
and in such capacity shall be invited and entitled to attend all meetings of the
IPT Board and each committee thereof. In the event that Jeffrey P. Cohen shall
cease to serve as Secretary of the Company for any reason, another individual
nominated by a majority of the Continuing Trustees shall be appointed to such
position and be so invited and entitled to attend such meetings. Without the
approval of a majority of the Continuing Trustees, AIMCO shall not, and shall
not permit any AIMCO-nominated Trustee to, remove a Continuing Trustee as a
trustee of the IPT Board or amend the IPT Charter unless such amendment shall
have been approved by a majority of the Continuing Trustees.

                  Section 6.11 Modification of Form of Transaction. Upon the
earlier to occur of (i) December 31, 2000 or (ii) such time (if ever) as any Law
is adopted or issued


                                       22

<PAGE>   24



after the date hereof which has the effect, as supported by the written opinion
of outside counsel for AIMCO, of prohibiting the Merger, or any court of
competent jurisdiction in the United States shall have issued an order, judgment
or decree permanently restraining, enjoining or otherwise prohibiting the
Merger, which order, judgment or decree has become final and nonappealable, IPT,
acting upon the recommendation of the Continuing Trustees, and AIMCO shall use
their best efforts to restructure the form of the transaction to one which has a
materially improved chance of completion and can be accomplished without
materially changing either the consideration to be received by IPT Shareholders
or the tax or other economic consequences of the transaction to AIMCO and its
Subsidiaries. Pending a definitive agreement between IPT and AIMCO providing for
such a restructured transaction, AIMCO and IPT shall continue to be obligated to
diligently pursue the consummation of the Merger on the terms contemplated by
this Agreement until such time, if ever, as this Agreement is terminated
pursuant to Section 8.1.

                  Section 6.12 Indemnification.

                  (a) "Losses" shall mean any and all actual costs or expenses
(including, without limitation, attorneys' fees billed at standard hourly rates,
investigation costs and remediation costs, interest, penalties and fines and all
legal and other costs, expenses and disbursements in giving testimony or
furnishing documents in response to a subpoena or otherwise), judgments, amounts
paid in settlement, fines, penalties, assessments, Taxes (as defined in the IFG
Agreement, but excluding Taxes arising from amounts paid to an Indemnitee (as
defined in Section 6.12(b)), losses, actions or causes of action, claims,
demands, damages, liabilities, obligations, awards, disbursements or assessments
of every kind, nature and description (including, without limitation, counsel's
fees billed at standard hourly rates and expenses, as and when incurred, in
connection with any action, claim or proceeding relating thereto).
Notwithstanding the foregoing, Losses shall be reduced to reflect any insurance
proceeds actually recovered by the Indemnitee relating to such claim, provided
that this reduction shall not be applied if to do so would excuse any insurer
from any obligation to cover any loss. If the Indemnitee receives insurance
proceeds after it receives indemnity hereunder, then the Indemnitee, within 10
days of receipt of such proceeds, shall pay to AIMCO the amount by which AIMCO's
payment would have been reduced if the insurance proceeds had been received
before the indemnity payments.

                  (b) AIMCO shall save, defend, indemnify and hold harmless each
person who is a trustee or officer of IPT, any person succeeding to their
position prior to the Closing Date, and their respective successors and heirs
(each, an "Indemnitee") to the fullest extent permitted by applicable law from
and against all Losses, as and when incurred, whether or not involving a third
party, that arise out of or are the result of the


                                       23

<PAGE>   25



fact that he is, was, or is to be, either prior to or after the execution of
this Agreement, a trustee, officer or employee of IPT, except that no Indemnitee
shall be entitled to be indemnified hereunder with respect to any Loss
determined to have been incurred (i) by reason of such Indemnitee's wilful
misconduct or (ii) with respect to attorney's fees and expenses which are not
reasonable, in each case in a written factual finding issued in a court
proceeding or other adjudication not subject to further appeal or issued in an
arbitration (as to (ii) only), and, in the event of such a finding, any funds
advanced to such Indemnitee pursuant to Section 6.12(c) and which are not found
to be within the provision of clause (i) or (ii) shall be returned by such
Indemnitee promptly to AIMCO. AIMCO shall make payments under this Section 6.12
within 30 days from the date that an Indemnitee has requested indemnification
hereunder.

                  (c) If any action, suit, proceeding or investigation is
commenced as to which an Indemnitee proposes to demand indemnification, he shall
notify AIMCO with reasonable promptness; provided, however, that failure to give
reasonably prompt notice to AIMCO shall not affect the indemnification
obligations of AIMCO hereunder except to the extent that the failure to so
notify has led to prejudice against AIMCO in such action, suit, proceeding or
investigation. The Indemnitee shall have the right to retain counsel of its own
choice to represent him; and such counsel shall, to the extent consistent with
its professional responsibilities, cooperate with AIMCO and any counsel
designated by AIMCO. AIMCO shall be liable only for any settlement of any claim
against an Indemnitee made with AIMCO's written consent, which consent shall not
be unreasonably withheld. AIMCO shall not, without the prior written consent of
an Indemnitee, settle or compromise any claim, or permit a default or consent to
the entry of any judgment in respect thereof, unless such settlement, compromise
or consent includes, as an unconditional term thereof, the giving by the
claimant to such Indemnitee of an unconditional release from all liability in
respect of such claim.

                  (d) Before enforcing his rights under this Section 6.12, an
Indemnitee must first demand indemnification from IPT pursuant to the
indemnification provisions set forth in the IPT Charter, IPT Bylaws and any
contractual arrangement between such Indemnitee and IPT. If, after ten business
days from the date that such Indemnitee had requested indemnification from IPT
pursuant to the indemnification provisions of the IPT Charter, IPT Bylaws and
any contractual arrangement between such Indemnitee and IPT, IPT has not paid
the Indemnitee's claim or satisfactorily responded to such Indemnitee's request,
as reasonably determined by the Indemnitee, the Indemnitee shall be free to
assert a claim for indemnification pursuant to this Section 6.12.

                  (e) Notwithstanding any other provision of this Agreement to
the contrary, this Section 6.12 and Section 6.13 shall survive the consummation
of the Merger and termination of this Agreement.

                  Section 6.13 Insurance. AIMCO and IPT agree that after the
date hereof and until the Effective Time, IPT shall maintain in full force and
effect, and AIMCO shall use its best efforts to cause IPT to maintain in full
force and effect, directors', trustees' and officers' liability insurance
covering the existing and Continuing Trustees, directors and officers of IPT and
its Subsidiaries which is no less favorable than the insurance coverage which is
in effect and covering such trustees, directors and officers on the date hereof.
AIMCO further agrees that following the Effective Time, the Surviving Entity
will maintain such insurance covering such persons, and each such person covered
by such insurance immediately prior to the Effective Time shall be named as
additional insureds.

                  Section 6.14 Conduct of IPT's Business Pending the Effective
Time.

                  Each of IPT and AIMCO covenants and agrees that from the date
of this Agreement until the Effective Time:

                  (a) IPT shall use its best efforts to maintain its listing on
the American Stock Exchange;

                  (b) none of IPT, IPLP or any Controlled IPT Entity (as defined
in Section 8.2) shall loan money to AIMCO or any Controlled AIMCO Entity (as
defined in Section 8.2);

as of the Closing Date; provided, however, that AIMCO and its Subsidiaries

otherwise act in the ordinary course of their business;

                        TERMINATION, AMENDMENT AND WAIVER

                  Section 8.1 Termination. This Agreement may be terminated at
any time prior to the Effective Time, whether before or after receipt of the IPT
Shareholders' Approval contemplated by this Agreement:

                  (a) by mutual written consent of a majority of the Continuing
Trustees and the AIMCO Board; or

                  (b) by AIMCO, by written notice to each of the Continuing
Trustees, if the Effective Time shall not have occurred on or before December
31, 2001; or

                  (c) by a majority of the Continuing Trustees, on behalf of
IPT, by written notice to AIMCO, if:

                           (i) the Effective Time shall not have occurred on or 
before December 31, 2001;

                                       29

<PAGE>   31



                           (ii) a majority of the Continuing Trustees shall
         determine in good faith that any proposal by or offer from any Person
         relating to any (A) acquisition of a substantial amount of assets of
         IPT or IPLP or any of the outstanding IPT Shares or IPLP partnership
         interests, (B) offer to purchase outstanding IPT Shares or IPLP
         partnership interests or (C) merger, consolidation, business
         combination, sale of substantially all assets, recapitalization,
         liquidation or similar transaction involving IPT or IPLP, other than
         the transactions contemplated by this Agreement (an "Alternative
         Proposal"), constitutes a proposal that is reasonably likely to be
         consummated and would, if consummated, result in a transaction which is
         more favorable, from a financial point of view, to IPT Shareholders
         than the transactions contemplated by this Agreement (a "Superior
         Proposal"); provided, however, that the Continuing Trustees may not
         terminate this Agreement pursuant to this Section 8.1(c)(ii) unless (x)
         five days shall have elapsed after delivery to AIMCO of a written
         notice of such determination by the Continuing Trustees and at all
         reasonable times during such five-day period the Continuing Trustees
         shall have cooperated with AIMCO in informing AIMCO of the terms and
         conditions of such Alternative Proposal and the identity of the person
         or group making such Alternative Proposal, with the objective of
         providing AIMCO a reasonable opportunity, during such five-day period,
         to propose a modification of the terms and conditions of this Agreement
         so that a business combination between IPT and AIMCO may be effected,
         (y) during such five-day period, the Continuing Trustees negotiate in
         good faith with AIMCO with respect to such proposed modifications, and
         (z) at the end of such five-day period, a majority of the Continuing
         Trustees continues to believe in good faith that such Alternative
         Proposal constitutes a Superior Proposal; or

                           (iii) AIMCO has taken any action that constitutes an
         anticipatory repudiation of this Agreement and has failed to cure such
         action within 10 days from receipt of notice (whether written or oral)
         from a majority of the Continuing Trustees.

                  Section 8.2 Effect of Termination. In the event of termination
of this Agreement by either IPT or AIMCO pursuant to Section 8.1, the effects
and consequences of such termination, and relative rights and obligations of
the parties as a result thereof, shall be as set forth in this Section 8.2 and
in the IPT Bylaws.

                 (a) GAAP. Unless the context otherwise clearly requires, all
accounting terms not expressly defined herein shall be construed, and all

the REIT hereunder shall be calculated based upon the EBITDA, Interest Expense,
Scheduled Amortization, Net Worth, Total Indebtedness, Gross Asset Value, and
other accounting items of the REIT, before any adjustment for the minority
interest attributable to the holders of limited partner interests in Borrower.

                                   ARTICLE II

                                  THE FACILITY

                 2.1      AMOUNTS AND TERMS OF COMMITMENTS.

                 (a)      Revolving Loans.


                           (i) Revolving Loans. Each Lender severally agrees, on
the terms and conditions hereinafter set forth, to make loans to Borrower other
than Swing Line Loans (each such loan, a "Revolving Loan" and all such loans
collectively, the "Revolver") from time to time on any Business Day during the
period from the Closing Date to the earlier of the Conversion Date or the
Revolver Maturity Date. The aggregate amount of the Revolver will not exceed the
lesser of the Lender's Revolving Commitment or such Lender's Commitment
Percentage of the Total Available Commitment.

                           (ii) Letters of Credit. If Borrower is in compliance
with the conditions for the making of Revolving Loans, Borrower may request on
or before the Revolver Maturity Date, through a Borrowing Notice, the Issuing
Lender to deliver from time to time Letters of Credit. Upon such request, the
Issuing Lender shall promptly issue the requested Letter of Credit in a form
approved by the Issuing Lender; provided that the maximum Letter of Credit
Liability at any one time outstanding may not exceed $25,000,000. Each Letter of
Credit must have an expiry date not later than the one year anniversary of its
issuance, unless otherwise agreed on by Issuing Lender, but in no event shall
the expiry date be later than one year after the Revolver Maturity Date. Each
drawing under a Letter of Credit is payable in full upon the date thereof by
Borrower, without notice or demand of any kind. Except with respect to an
Outside Period Letter of Credit which is drawn upon after the Revolver Maturity
Date, Borrower may obtain, in accordance with the conditions applicable to
advances of the Revolving Loans, a Revolving Loan in the amount drawn on a
Letter of Credit to reimburse BofA as the Issuing Lender for such amount. Other
than draws on an Outside Period Letter of Credit after the Revolver Maturity
Date, Borrower's liability to reimburse Issuing Lender for amounts drawn under
Letters of Credit is included within the terms "Revolving Loan" and "Loan" for
all purposes of this Agreement, and any amounts drawn shall bear interest



                                       39
<PAGE>   40



until paid in full (whether out of the proceeds of a Revolving Loan otherwise
permitted hereunder or otherwise) at the Base Rate plus the Applicable Base Rate
Margin, subject to Section 2.9(c). Amounts drawn on an Outside Period Letter of
Credit after the Revolver Maturity Date are due and payable by Borrower to Agent
immediately and shall accrue interest until paid at the Base Rate plus three
percent (3%). Borrower's obligations to repay drawings under any Letter of
Credit and all other amounts payable to Issuing Lender, Agent or any other
Lender hereunder shall be absolute, irrevocable and unconditional under any and
all circumstances whatsoever and irrespective of any set-off, counterclaim or
defense to payment which Borrower may have or have had against Issuing Lender,
Agent or any other Lender (except such as may arise out of Issuing Lender's,
Agent's or any other Lender's gross negligence or willful misconduct hereunder)
or any other Person, including, without limitation, any setoff, counterclaim or
defense based upon or arising out of:

                           (A) Any lack of validity or enforceability of this
Agreement or any of the other Loan Documents or such Letter of Credit;

                           (B) Any amendment or waiver of or any consent to or
departure from the terms of such Letter of Credit or the Loan Documents;

                           (C) The existence of any claim, setoff, defense or
other right which Borrower or any other Person may have at any time against, any
beneficiary or any transferee of such Letter of Credit (or any Person for whom
any such beneficiary or any such transferee may be acting), Issuing Lender,
Agent or any other Lender or any other Person, whether in connection with such
Letter of Credit, the Loan Documents or any unrelated transaction;

                           (D) Any demand, statement or any other document
presented under such Letter of Credit proving to be forged, fraudulent, invalid
or insufficient in any respect, or any statement therein being untrue or
inaccurate in any respect whatsoever or any variations in punctuation,
capitalization, spelling or format of the drafts or any statements presented in
connection with any drawing under such Letter of Credit;

                           (E) The surrender or impairment of any security for
the performance or observance of any of the terms of such Letter of Credit or
the Loan Documents; and



                                       40
<PAGE>   41



                                  (F) The failure, for any reason, of any Lender
to fund advances to Borrower hereunder for any purpose.

Nothing contained herein shall constitute a waiver of any rights or remedies of
Borrower against Issuing Lender, Agent or any other Lender arising out of the
gross negligence or willful misconduct of Issuing Lender, Agent or any such
other Lender.

                          (iii)   Limits on Revolving Loans and Letters of 
Credit. Notwithstanding anything to the contrary set forth herein, after giving
effect to any Revolving Loan and after the issuance of any Letter of Credit, in
no event shall the Outstanding Amount exceed the Total Available Commitment.
Within the limitations set forth in this Section 2.1(a), and subject to the
other terms and conditions hereof, Borrower may borrow or request Letters of
Credit to be issued under this Section 2.1(a), repay or prepay pursuant to
Section 2.5 or otherwise cause Letters of Credit to be cancelled or to expire
undrawn and reborrow (subject to the limitations set forth hereinbelow) or
request additional Letters of Credit to be issued pursuant to this Section 2.1.

                          (iv)    [Intentionally Omitted]

                 (b) Revolving Credit Usage. Borrower shall use the proceeds of
all Revolving Loans and all Letters of Credit for general partnership purposes,
including, without limitation, acquisitions of multi-family apartment projects
and other real estate assets, Investments in Persons engaged primarily in the
business of owning or managing real estate assets and other Investments
permitted hereunder, Capital Expenditures and redevelopment projects.

                 (c) Amounts and Terms of Term Loan; Conversion. On or before
the Revolver Maturity Date, if (x) no Default has then occurred and is
continuing, provided that if the Agent shall have actual notice of such Default,
it shall have provided notice thereof to Borrower and (y) no Event of Default
has then occurred and is continuing, Borrower may notify Agent that it elects
both to terminate the Revolver as of the Revolver Maturity Date then in effect
and effective as of the Conversion Date to maintain its Loans then outstanding
as Term Loans pursuant to Section 2.1(c) (the "Conversion Option"); provided,
further, however, that Borrower shall have delivered to Agent a Revolver to Term
Certificate as a condition precedent to the Conversion Option and paid to Agent,
for the ratable benefit of the Lender, the conversion fee as provided in Section
2.10(d). Each Lender severally agrees, on the terms and conditions hereinafter
set forth, and provided all Conversion Conditions have been satisfied, to
continue or convert loans to Borrower (each such loan, a "Term Advance" and all
such loans collectively the "Term


                                       41

<PAGE>   42



Loan") from time to time on any Business Day from the Conversion Date to the
Term Loan Maturity Date, in an aggregate amount not to exceed at any time the
Term Commitment; provided, however, that after giving effect to any Term
Advance, the Outstanding Amount shall not exceed the then applicable Total
Available Commitment. Once repaid or prepaid, Borrower may not reborrow any Term
Advance.

                 (d)      Swing Line Loans.

                          (i) Subject to the terms and conditions hereof, if
necessary to meet Borrower's funding deadlines, BofA agrees to make Swing Line
Loans to Borrower at any time prior to the Revolver Maturity Date, not to exceed
an amount at any one time outstanding equal to the lesser of (A) $30,000,000,
and (B) the Total Available Commitments. Swing Line Loans shall constitute
Loans for all purposes hereunder.

                          (ii) Each request for a Swing Line Loan shall be in an
amount
equal to $1,000,000 or a greater integral multiple of $50,000. Borrower may
request a Swing Line Loan by submitting a Borrowing Notice to Agent and BofA.
Such Borrowing Notice must be received by Agent and BofA no later than 2:00
p.m. on the specified borrowing date for such Swing Line Loan. Provided that
Borrower shall have given telephonic notice to Agent and BofA no later than 2:00
p.m. on the specified borrowing date for such Swing Line Loan BofA shall make
such Swing Line Loan available to Borrower by deposit in such of Borrower's
accounts with BofA in Los Angeles, California, as Borrower designates in
writing, on or before at 3:00 p.m. on such borrowing date.

                          (iii) If necessary to meet Borrower's funding
deadlines, Agent
may treat any Borrowing Notice as a request for a Swing Line Loan from Borrower
and BofA may fund it as a Swing Line Loan. Within 2 Business Days after each
Swing Line Loan is funded, BofA and Agent shall request that each Lender, and
each Lender shall, on the first (1st) Business Day after such request is made,
prepay one or more Swing Line Loans in an amount equal to such Lender's
Commitment Percentage of such Swing Line Loans by funding under such Lender's
Note, such purchase to be made in accordance with the terms of Section 2.3 of
this Agreement just as if such Lender were funding a Base Rate Loan directly to
Borrower under its Note (such that all Lenders other than BofA shall fund only
under their respective Notes and not under the Swing Line Loan Note). Unless
BofA had actual knowledge when BofA funded a Swing Line Loan that Borrower had
not satisfied the conditions in this Agreement to obtain a borrowing, each
Lender's obligation to prepay the Swing Line Loans shall be absolute and
unconditional and shall not be affected by any circumstance, including, without
limitation (i) any set-off, counterclaim, recoupment, defense, or other right
which such Lender or any other



                                       42
<PAGE>   43



Person may have against BofA or any other Person for any reason whatsoever, (ii)
the occurrence or continuance of a Default or the termination of any Lender's
Commitment, (iii) the occurrence of any Material Adverse Effect, (iv) any breach
of this Agreement or any other Loan Document by Borrower, any of its Affiliates,
Agent, or any other Lender, or (v) any other circumstance, happening, or event
whatsoever, whether or not similar to any of the foregoing. Any portion of a
Swing Line Loan not so prepaid may be treated by BofA as a Loan which was not
funded by the non-purchasing Lenders as contemplated in Section 2.14 of this
Agreement, and as a funding by BofA under the Aggregate Commitment in excess of
BofA's Commitment. Each Swing Line Loan, once so prepaid, shall cease to be a
Swing Line Loan for the purposes of this Agreement, but shall be deemed a
borrowing made under the Aggregate Commitment and each Lender's Commitment.
Each Swing Line Loan shall be a Base Rate Loan.

                 2.2 NOTE. Each Loan (other than a Swing Line Loan) will be
evidenced by a Note dated the Closing Date payable to the order of the
applicable Lender in the amount of its Commitment and each Swing Line Loan will
be evidenced by a Swing Line Note dated the Closing Date and payable to BofA in
the amount of $30,000,000. The date, amount and maturity of each Loan and the
amount of each principal payment will be endorsed by the applicable Lender on
the schedules annexed to the Note. Borrower irrevocably authorizes each Lender
to endorse its Note (including authorizing BofA to endorse the Swing Line Note),
and each Lender's record will be conclusive absent manifest error; provided,
however, that a Lender's failure to make, or an error in making, a notation
thereon shall not affect Borrower's obligations under this Agreement or under
any Note.

                 2.3      PROCEDURE FOR BORROWING.

                 (a) Borrowing Notice. Each Loan shall be made in accordance
with the terms of a Borrowing Notice delivered by Borrower to Agent, as follows:

                          (i) Designation of Interest Rate. Borrower may elect
that a Loan be made as a LIBOR Loan or a Base Rate Loan; provided that, unless
the Agent otherwise agrees in writing, Borrower may not elect that a Loan be
made as a LIBOR Loan, if in addition to such Loan there will be more than five
(5) LIBOR Loans outstanding.

                          (ii) Timing of Notice. Each Borrowing Notice must be
submitted to and received by Agent before 9:00 a.m. (California time) as

include the following information:

                                  (A) an exact amount for the Loan (LIBOR Loans
must be in a minimum amount of $1,000,000 with additional increments of $100,000
and there are no restrictions on the amount of Base Rate Loans);

                                  (B) if the Loan is a LIBOR Loan, the
applicable Interest Period (if no Interest Period is specified for a requested
LIBOR Loan, the Loan will be made as a Base Rate Loan); and

                                  (C) in the case of a proposed Letter of
Credit, a completed letter of credit application on the Issuing Lender's
standard form substantially in the form of Exhibit G.

                 (b) Notice to Lenders. When Agent receives a Borrowing Notice
in conformity with Section 2.3(a), it shall promptly notify each Lender thereof
and of the amount of such Lender's Commitment Percentage of the requested Loan
and in the case of a Letter of Credit it shall notify each Lender promptly upon
the issuance together with such Lender's participation in the requested Letter
of Credit.

                 (c) Funding of Commitment. Each Lender shall fund the amount of
its Commitment Percentage of the requested Loan to Agent, for Borrower's
account, at the Payment Office by 9:00 a.m. (California time) on the specified
borrowing date in funds immediately available to Agent. Unless any applicable
condition in Article IV is not satisfied, Agent will then make the amounts
received from the Lenders available to Borrower as directed in written payment
instructions from Borrower.

                 (d) Frequency of Borrowings. No more than four (4) Borrowing
Notices may be given in any calendar month except with respect to Swing Line
Loans for which there shall be no such limitation.

                 2.4 CONVERSION AND CONTINUATION ELECTIONS.

<PAGE>   45



                 (a) Conversion/Continuation Notice. Each conversion or
continuation of an outstanding Base Rate Loan or LIBOR Loan shall be made upon
the irrevocable written notice (including notice via facsimile confirmed
immediately by a telephone call) of Borrower in the form of a
Conversion/Continuation Notice, as follows:

                          (i) Designation of Interest Rate. Borrower shall have
the right to make the following elections with respect to the conversion or
continuation of any outstanding Base Rate Loan or LIBOR Loan: (A) to convert, on
any Business Day, any Base Rate Loan, in a minimum principal amount of
$1,000,000 or an integral multiple of $100,000 in excess thereof, into a LIBOR
Loan; or (B) to convert, on the last day of any Interest Period with respect to
a LIBOR Loan (or, on any other day of any Interest Period, upon payment of any
loss or expense incurred or sustained by any Lender with respect to the early
termination of such LIBOR Loan prior to the last day of the Interest Period as
provided in Section 3.4), such LIBOR Loan into a Base Rate Loan; or (C) to
continue, on the last day of any Interest Period with respect to a LIBOR Loan
(or, on any other day of any Interest Period, upon payment any loss or expense
incurred or sustained by any Lender with respect to the early termination of
such LIBOR Loan prior to the last day of the Interest Period as provided in
Section 3.4), such LIBOR Loan (or any part thereof in a minimum principal amount
of $1,000,000 or an integral multiple of $100,000 in excess thereof) for a
subsequent Interest Period; provided, that unless the Agent shall otherwise
agree in writing, Borrower may not elect to have any outstanding LIBOR Loan or
Base Rate Loan (or any portion thereof) continued as or converted into a LIBOR
Loan if (A) a Default or Event of Default shall exist, (B) after giving effect
to such continuation or conversion there shall be more than five different LIBOR
Loans outstanding or the outstanding principal amount of any LIBOR Loans shall
have been reduced, by payment, prepayment, or partial conversion to less than
$1,000,000.

                          (ii) Timing of Notice. Each Conversion/Continuation
Notice shall be submitted to and received by the Agent prior to 9:00 a.m.
(California time): (A) at least three (3) Business Days prior to the Pricing
Conversion Date of any outstanding Loan to be converted into or continued as a
LIBOR Loan; and (B) at least one (1) Business Day prior to the Pricing
Conversion Date of any outstanding Loan to be converted into or continued as a
Base Rate Loan.

                          (iii) Contents of Notice. The Conversion/Continuation
Notice shall set forth the following information with respect to the Loan
subject thereto: (A) the Pricing Conversion Date, which shall be a Business Day;
(B) the amount of the LIBOR Loan or Base Rate Loan to be converted or continued;
(C) whether such Loan is to be converted into/continued as a LIBOR Loan or a
Base Rate Loan; and (D) if such Loan (or



                                       45
<PAGE>   46



any portion thereof) is to be converted into/continued as a LIBOR Loan, the
applicable Interest Period.

                 (b) Automatic Conversions. Any outstanding LIBOR Loan shall
automatically convert to a Base Rate Loan, effective on the last day of the
applicable Interest Period, if as of such date:

                          (i) Default; Event of Default. A Default or Event of
Default shall exist;

                          (ii) Failure to Provide Notice. Borrower shall have
failed to submit a Conversion/Continuation Notice for such Loan in compliance
with the terms of Section 2.4(a); or

                          (iii) Failure to Maintain Minimum Loans. If the
aggregate outstanding principal amount of LIBOR Loans having the same Interest
Period shall have been reduced, by payment, prepayment, or partial conversion to
be less than $1,000,000.

                 (c) Notice to Lenders. Upon receipt of a
Conversion/Continuation Notice conforming with the terms of Section 2.4(a), or
an automatic conversion pursuant to Section 2.4(b), the Agent shall promptly
notify each Lender thereof. All conversions and continuations shall be made pro
rata according to the respective outstanding principal amounts of the Loans
converted or continued.

                 2.5 OPTIONAL PREPAYMENTS; OPTIONAL REDUCTIONS OF THE REVOLVING
COMMITMENT.

                 (a) Subject to Section 3.4, Borrower may, at any time and from
time to time, ratably prepay Loans in whole or in part, in an aggregate minimum
amount of $1,000,000 or an integral multiple of $100,000 in excess thereof, upon
(a) at least three (3) Business Days' prior notice, if the Loans to be prepaid
are LIBOR Loans, and (b) at least one Business Day's prior notice, if the Loans
to be prepaid are Base Rate Loans. Such notice of prepayment shall specify (i)
the amount of such prepayment, (ii) the date of such prepayment, which shall be
a Business Day, and (iii) whether such prepayment is of LIBOR Loans, Base Rate
Loans, or any combination thereof. Such notice shall not thereafter be revocable
by Borrower and the Agent shall promptly notify each Lender thereof and of such
Lender's Commitment Percentage of such prepayment. If a prepayment notice is
given, the payment amount specified therein shall be due and payable on



                                       46
<PAGE>   47



the date specified therein, together with accrued interest to such date on the
amount prepaid and any amounts required to be paid pursuant to Section 3.4.

                 (b) At any time prior to the Conversion Date, Borrower may,
upon not less than five (5) Business Days' prior notice to Agent, terminate the
aggregate Revolving Commitment of all Lenders or permanently reduce the
aggregate Revolving Commitment of all Lenders by an aggregate minimum amount of
$1,000,000 or an integral multiple of $100,000 in excess thereof; provided that
no such termination or reduction shall be permitted if, after giving effect
thereto and to any prepayments of the Loans made on the effective date thereof,
the Outstanding Amount would exceed the amount of the Total Available Commitment
and, provided, further, that once reduced in accordance with this Section
2.5(b), the aggregate Revolving Commitment of all Lenders may not be increased.
Any reduction of the aggregate Revolving Commitment of all Lenders shall be
applied to each Lender's Revolving Commitment in accordance with such Lender's
Revolving Commitment Percentage. If the Revolving Commitments are terminated in
their entirety, all accrued commitment fees under Section 2.10(c) to, but not
including, the effective date of such termination shall be payable on the
effective date of such termination.

                 2.6      MANDATORY PREPAYMENTS OF LOANS; MANDATORY AMORTIZATION
AND REDUCTIONS.

                 (a) Total Available Commitment. If at any time the Outstanding
Amount exceeds the then applicable Total Available Commitment, Borrower shall
immediately prepay Loans (or cause Letters of Credit to be cancelled) in an
amount sufficient to reduce the Outstanding Amount to the then applicable Total
Available Commitment.

                 (b) Amortization. On the last Business Day of each March, June,
September and December following the Conversion Date, Borrower shall repay or
prepay Loans in an aggregate amount equal to one twelfth (1/12th) of the initial
outstanding balance of the Term Loan as of the Conversion Date.

                 2.7 APPLICATION OF PROCEEDS. Unless otherwise instructed by
Borrower, any prepayments pursuant to Section 2.5 or Section 2.6 made (i) on a
day other than the last day of an Interest Period for any Loan shall be applied
first to any Base Rate Loans then outstanding and then to any LIBOR Loans then
outstanding, in the inverse order of such LIBOR Loans' stated maturities and
(ii) on the last day of an Interest Period for any LIBOR Loan shall be applied
first to such maturing LIBOR Loan, then to any



                                       47
<PAGE>   48



Base Rate Loans outstanding, and then to any other LIBOR Loans then outstanding,
in the inverse order of such LIBOR Loans' stated maturities.

                 2.8 REPAYMENT. Subject to Section 2.6, unless the Revolver has
been converted into the Term Loan, Borrower shall repay all Obligations on the
Revolver Maturity Date and, if the Revolver has been converted into the Term
Loan, shall repay all Obligations on the Term Loan Maturity Date.

                 2.9 INTEREST.

                 (a) Rates. Subject to Section 2.9(c), each Loan shall bear
interest on the outstanding principal amount thereof from the date such Loan is
made until the date such Loan becomes due, at a rate per annum equal to the LIBO
Rate or the Base Rate, as the case may be, plus the Applicable Margin.

                 (b) Payment Dates. Interest on each Loan shall be payable in
arrears on each Interest Payment Date and the Revolver Maturity Date or, if the
Revolver has been converted into the Term Loan, the Term Loan Maturity Date.
Interest shall also be payable on the date of any prepayment of Loans pursuant
to Section 2.5 or Section 2.6 for the portion of the Loans so prepaid. During
the existence of any Event of Default, interest shall be payable on demand.

                 (c) Default Rates. While any Event of Default exists or after
acceleration and during the continuation thereof, and after as well as before
any entry of judgment thereon, Borrower shall pay interest (after as well as
before judgment to the extent permitted by law) on all outstanding Obligations
at a rate per annum which is determined by increasing the Applicable Margin then
in effect by three percent (3%) per annum; provided, however, that, on and after
the expiration of the Interest Period applicable to any LIBOR Loan outstanding
on the date of occurrence of such Event of Default or acceleration, the
outstanding Obligations shall, during the continuation of such Event of Default
or after acceleration and during the continuation thereof, bear interest at a
fluctuating rate per annum equal to the Base Rate plus three percent (3%).

                 (d) Limitations for Applicable Law. Anything herein to the
contrary notwithstanding, payments of interest shall not be required for any
period for which interest is computed hereunder, to the extent (but only to the
extent) that contracting for or receiving such payments by the respective Lender
would be contrary to the provisions of any law applicable to such Lender
limiting the highest rate of interest which may be



                                       48
<PAGE>   49



lawfully contracted for, charged or received by such Lender, and in such event
Borrower shall pay such Lender interest at the highest rate permitted by
applicable law.

                 2.10 FEES.

                 (a) Arrangement Fee. Upon the due execution and delivery of
this Agreement by Borrower, the Agent and each of the Lenders which are the
initial Lenders party to this Agreement, Borrower shall pay to BofA an

Lender ratably a commitment fee on the average daily unused portion of such
Lender's Commitment Percentage of the Aggregate Commitment (exclusive of the
average daily undrawn available amount of all Letters of Credit outstanding and
the balance of any outstanding Swing Line Loans), regardless of whether or not
such Aggregate Commitment is available to be advanced hereunder, equal to
0.1875% per annum. Such commitment fee shall accrue from the Closing Date to the
earlier of the Conversion Date or the Revolver Maturity Date and shall be due
and payable in arrears quarterly on the first Business Day of each April, July,
October and January with respect to the prior calendar quarter, commencing on
the first Business Day of April, 1998, on the Revolver Maturity Date, and on any

                 (d) Conversion Fee. On the Conversion Date, Borrower shall pay

                 (e) Unencumbered Asset Pool Adjustment Fee. Without limiting
Borrower's obligations to pay costs and expenses under Section 2.13 and 10.4,
upon the addition of a project to the Unencumbered Asset Pool on or after the
date hereof, Borrower shall pay to the Agent for the ratable benefit of the
Lenders an Unencumbered Asset Pool Property adjustment fee in the amount of
$2,000 per property for each such



                                       49
<PAGE>   50



Property added to the Unencumbered Asset Pool on or after the date hereof after
the first five (5) approved Properties.

                 (f) Letter of Credit Fees.

                          (i) Borrower shall pay to Agent for the Issuing
Lender's sole benefit an issuance fee in the amount of 0.25% of the initial face

                          (ii) Borrower shall pay to Agent for the ratable
benefit of the Lenders an annual fee in an amount equal to the Applicable LC Fee
which fee shall be determined on the first Business Day of each April, July,
October and January for the prior calendar quarter.

                          (iii) The Applicable LC Fee will accrue when each

shall be due and payable in arrears quarterly on the first Business Day of each

other date on which the Revolver is paid in full and the Revolving Commitment
permanently terminated.

                 (g) Accrued Fees. Borrower ratifies and confirms its agreement
to pay all accrued but unpaid fees under the Previous Credit Agreement, which
obligation shall be paid promptly upon demand by the Agent and shall not be
superseded by this Agreement.

                 2.11  COMPUTATION OF FEES AND INTEREST.

                 (a) Computation Period. All computations of fees and interest
under this Agreement shall be made on the basis of a 360-day year and actual
days elapsed. Interest and fees shall accrue during each period for which
interest or fees are computed from the first day thereof to the last day
thereof.

                 (b) Notice. The Agent shall, with reasonable promptness, notify
Borrower and the Lenders of each determination of a LIBO Rate, provided that no
failure to do so shall relieve Borrower of any obligation hereunder. Any change
in the interest rate on a Loan resulting from a change in the Reserve Percentage
(as defined in the definition of "LIBO Rate") shall become effective as of the
opening of business on the day on which such change becomes effective. The Agent
shall with reasonable promptness notify Borrower and the Lenders of the
effective date and the amount of each such



                                       50
<PAGE>   51



change, provided that no failure to do so shall relieve Borrower of any
obligation hereunder. Each determination of an interest rate by the Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
Borrower and the Lenders in the absence of manifest error.

                 (c) Detail of Calculation. The Agent shall, at the request of
Borrower or any Lender, deliver to Borrower or such Lender, as the case may be,
a statement showing the quotations used by the Agent in determining any interest
rate.

                 2.12     PAYMENTS BY BORROWER.

                 (a) Terms of Payments. All payments (including prepayments) to
be made by Borrower on account of principal, interest, fees and other amounts
required hereunder shall be made without setoff or counterclaim and shall,
except as otherwise expressly provided herein, be made to the Agent for the
ratable account of the Lenders at the Payment Office, in dollars and in
immediately available funds, no later than 9:00 a.m. (California time) on the
date specified herein. The Agent shall promptly distribute to each Lender such
Lender's Commitment Percentage (or other applicable share as expressly provided
herein) of such principal, interest, fees or other amounts (in like funds as
received). Any payment which is received by the Agent later than 9:00 a.m.
(California time) shall be deemed to have been received on the immediately
succeeding Business Day, and any applicable interest or fee shall continue to
accrue.

                 (b) Business Days. Whenever any payment under this Agreement
becomes due on a day other than a Business Day, the payment will be made on the
next succeeding Business Day, and the extension of time included in the
computation of interest or fees, as applicable; subject to the provisions set
forth in the defined term Interest Period.

                 (c) Reliance of Agent on Payments by Borrower. Unless the Agent
shall have received notice from Borrower prior to the date on which any payment
is due to the Lenders hereunder that Borrower will not make such payment in
full, the Agent may assume that Borrower has made such payment in full to the
Agent on such date, and the Agent may (but shall not be required to), in
reliance upon such assumption, cause to be distributed to each Lender on such
due date the amount then due such Lender. If and to the extent Borrower shall
not have made such payment in full to the Agent, each Lender shall repay to the
Agent on demand such amount distributed to such Lender, together with interest
thereon for each day from the date such amount is distributed to



                                       51
<PAGE>   52



such Lender until the date such Lender repays such amount to the Agent, at the
Federal Funds Rate as in effect for each such day.

                 2.13     UNENCUMBERED ASSET POOL; ADDITIONS AND EXCLUSIONS OF
PROPERTIES.

                 (a) Unencumbered Asset Pool. As of the Closing Date, the
Unencumbered Asset Pool consists of the Initial Unencumbered Asset Pool and
each Property therein is a Class B or better apartment project. Additional
Properties, which in all cases must be Class B or better apartment projects, may
be offered by Borrower and shall be included in the Unencumbered Asset Pool only
in accordance with the following (and any other applicable terms and conditions
contained in this Agreement):

                          (i) Request for Total Available Commitment Increase.
Borrower from time to time may request that Qualified Properties that have been
Stabilized be included in the Unencumbered Asset Pool by written request to the
Agent.

                          (ii) Acceptance of Qualified Properties. The Lenders
may in their sole discretion, and after performing such due diligence as the
Lenders desire in their sole discretion, accept or reject any Qualified Property
which is Stabilized offered as an addition to the Unencumbered Asset Pool,
unless the Qualified Property is a Class B or better apartment project, in which
case the Lenders must be reasonable in their acceptance or rejection of such
Qualified Property; provided, however that if Borrower then has an Investment
Grade Credit Rating and no Default or Event of Default has occurred and is
continuing, then the Lenders shall accept any Qualified Property which is a
Class B or better apartment project and Stabilized as an addition to the
Unencumbered Asset Pool unless Agent or any Lender reasonably determines that
the Property is in violation of applicable Environmental Laws. Borrower shall at
its expense provide the Agent and the Lenders with the following due diligence
materials and information with respect to any project offered as an addition to
the Unencumbered Asset Pool, at least thirty (30) days prior to the delivery by
Borrower of a Borrowing Notice relating to the project:

                                  (A) the Due Diligence Package;

                                  (B) written advice relating to such lien and
judgment searches as the Agent shall have requested of Borrower with respect to
such Property;




                                       52
<PAGE>   53



                                  (C) an environmental site assessment with
respect to such Property, dated as of a recent date, prepared by a qualified
firm acceptable to the Agent, identifying any conditions or operations on such
property that are not in compliance with any Environmental Laws and any
Hazardous Materials located thereon, showing Estimated Remediation Costs, if
any, and stating that there are no conditions on such property or other items
requiring further investigation or remediation, and any follow-on or
supplemental report required by the Agent, together with the Agent's standard
form Environmental Questionnaire and Disclosure Statement completed by Borrower;

                                  (D) if required by the Agent, a report
regarding structural, siding, engineering, seismic and code/legal compliance
(including compliance with the Americans With Disabilities Act) matters;

                                  (E) current, certified rent roll and other
reports of the financial and operating results (for the most recent 12-month
period) and projections for the property setting forth in such format as the
Agent may require the information relevant to such property necessary to
calculate the Revolver DSC Principal Limit;

                                  (F) if required by Agent, copies of the
standard lease form and the property management agreement and other material
operating agreements or contracts relating to the property;

                                  (G) if required by the Agent, evidence of the
zoning, subdivision and entitlements status of the property, including, without
limitation, copies of the certificate of occupancy and any other material
permits, licenses or approvals required for the property;

                                  (H) a copy of the purchase and sale
agreement(s) by which Borrower or such Wholly-Owned Subsidiary has acquired the
property;

                                  (I) such other items as the Agent may
reasonably request.

Borrower acknowledges that the review of the due diligence materials described
in this Section 2.13(a)(ii) will require advance notice to the Agent and the
Lenders, and Borrower agrees to provide as much advance notice as possible to
achieve timely review of such materials.

<PAGE>   54



                          (iii) Conditions to Inclusion of Proposed Properties
in Unencumbered Asset Pool. Each of the following conditions must be satisfied
(or waived by the Agent in writing) prior to the Lenders' acceptance of any
Qualified Property into the Unencumbered Asset Pool:

                                  (A) Acceptances. The Lenders shall have agreed
to accept the apartment project offered by Borrower for inclusion into the
Unencumbered Asset Pool as provided in Section 2.13(a)(ii), and Agent shall have
so notified Borrower in writing. Any such acceptance shall be subject to the
satisfaction of the other conditions set forth in this Section 2.13(a)(iii).

                                  (B) Officers' Certificate. Borrower shall have
delivered to the Agent a certificate of two Responsible Officers substantially
in the form of Exhibit H confirming (i) that all conditions precedent set forth
in this Section 2.13(a)(iii) (other than those based solely upon the approval of
the Agent or the Lenders) have been satisfied with respect to such project; (ii)
that all financial and operating information delivered to the Agent pursuant to
Section 2.13(a)(ii), subject to audit, is complete and correct to the knowledge
of Borrower and setting forth in detail the calculation of the Revolver DSC
Principal Limit; (iii) Borrower's purchase price for the property, upon which
the Agent and the Lenders are entitled to rely; and (iv) that the Person owning
the proposed project has incurred no Indebtedness other than as permitted under
Sections 7.2(a) through (h) inclusive.

                          (iv) Palencia Property. The Palencia Property is
hereby added to the Unencumbered Asset Pool for purposes of compliance with
Articles V, VI and VII of the Credit Agreement, notwithstanding the Liens
encumbering such Property, which Liens shall constitute Permitted Liens;
provided, however, that it shall be excluded from the Unencumbered Asset Pool
upon the occurrence of (i) any event described in Section 2.13(b) or (ii) any
pledge, transfer, sale, exchange, remarketing or refunding of the Palencia Bond.
Any calculations in respect of Unencumbered Asset Pool Value shall not take into
account any amount whatsoever in respect of the Palencia Property, other than
the Palencia Bond Value.

                          (v) Captiva Club Property. Notwithstanding any
contrary provision of this Section 2.13, if the Captiva Club Property is a
Qualified Property it shall be added to the Unencumbered Asset Pool,
notwithstanding that it is not a Stabilized Property; provided, however, that if
the Captiva Club Property fails to achieve an 85% occupancy level by March 1,
1999, then thereafter it shall be excluded from the Unencumbered Asset Pool.

                 (b) Exclusion of Property From the Unencumbered Asset Pool. Any
Property will automatically have a value of zero for purposes of calculating the
Total


                                       54
<PAGE>   55



Available Commitment and will be excluded from the Unencumbered Asset Pool if,
after the date the Property enters the Unencumbered Asset Pool,

                          (i) a material adverse change in the environmental
condition of the Property from that described in the materials described in
Section 2.13(a)(ii) occurs that is not adequately remediated in accordance with
all applicable Environmental Laws within thirty (30) days after demand from
Agent to Borrower, or such Property shall incur Property Liabilities in excess
of 10% of the value of such Property; and

                          (ii) immediately upon any sale, transfer or
encumbrance of such Property (or of the beneficial, stock, equity, membership or
partnership interest in the owner of such Property, other than to Borrower or
one of its Qualified Wholly Owned Subsidiaries; provided, however, that prior to
any transfer to any Qualified Wholly-Owned Subsidiary, Borrower shall have
received the prior written consent of the Agent, which consent shall not be
unreasonably withheld or delayed); and

                          (iii) at the end of the calendar quarter in which any
such Property ceases to be Stabilized, as set forth in the Compliance
Certificate for such calendar quarter.

                 2.14     PAYMENTS BY LENDERS TO AGENT.

                 (a) Reliance of Agent on Payments by the Lenders. Unless Agent
has received notice from a Lender on the Closing Date or, with respect to each
borrowing after the Closing Date, at least one Business Day prior to the date of
any proposed borrowing, that such Lender will not make available to the Agent
for the account of the Company the amount of that Lender's Commitment Percentage
of the Loan to be funded on such date, Agent may assume that each Lender has
made such amount available to the Agent on the borrowing date, and Agent may
(but shall not be required to), in reliance upon such assumption, make available
to the Company a corresponding amount on such date. If and to the extent any
Lender shall not have made its full amount available to Agent and Agent in such
circumstances has made available to the Company such amount, that Lender shall
on the next Business Day following the date of such borrowing make such amount
available to the Agent, together with interest at the Federal Funds Rate for and
determined as of each day during such period. A certificate of Agent submitted
to any Lender with respect to amounts owing under this Section 2.14(a) shall be
conclusive, absent manifest error. If such amount is so made available, such
payment to the Agent shall constitute such Lender's Loan (as of the date of the
borrowing) for all purposes of this Agreement. If such amount is not made
available to the Agent on the next Business Day following the borrowing date,
the Agent shall notify Borrower of such failure to fund and, upon demand by the
Agent, Borrower shall



                                       55
<PAGE>   56



pay such amount to the Agent for the Agent's account, together with interest
thereon for each day elapsed since the date of such borrowing, at a rate per
annum equal to the interest rate applicable at the time to the Loans comprising
such borrowing, and Borrower may exercise any rights and remedies it may have
against the Lender that so failed to fund.

                 (b) Obligations of Agent; Lender. The failure of any Lender to
make any Loan on any date of borrowing shall not relieve any other Lender of any
obligation hereunder to make a Loan on the date of such borrowing, but no Lender
shall be responsible for the failure of any other Lender to make the Loan to be
made by such other Lender on the date of any borrowing.

                 2.15 SHARING OF PAYMENTS, ETC. If, other than as expressly
contemplated elsewhere herein, any Lender shall obtain on account of the Loans
made by it any payment (whether voluntary, involuntary, through exercise of any
right of setoff, or otherwise) in excess of its Commitment Percentage of
payments on account of the Loans obtained by all the Lenders, such Lender shall
forthwith (a) notify the Agent of such fact, and (b) purchase from the other
Lenders such participations in the Loans made by them as shall be necessary to
cause such purchasing Lender to share the excess payment ratably with each of
them; provided, however, that if all or any portion of such excess payment is
thereafter recovered from the purchasing Lender, such purchase shall to that
extent be rescinded and each other Lender shall repay to the purchasing Lender
the purchase price paid thereto together with a percentage (calculated by
dividing (i) the amount of such paying Lender's required repayment by (ii) the
total amount so recovered from the purchasing Lender) of any interest or other
amount paid or payable by the purchasing Lender in respect of the total amount
so recovered. Borrower agrees that any Lender so purchasing a participation from
another Lender pursuant to this Section 2.15 may, to the fullest extent
permitted by law, exercise all of such purchasing Lender's rights of payment
(including the right of setoff, but subject to Section 10.9) with respect to
such participation as fully as if such purchasing Lender were the direct
creditor of Borrower in the amount of such participation. The Agent shall keep
records (which shall be conclusive and binding in the absence of manifest error)
of participations purchased pursuant to this Section 2.15 and shall in each case
notify the Lenders following any such purchases.

                 2.16     PARTICIPATION PURCHASED BY LENDERS IN THE LETTER OF 
CREDIT LIABILITY.

                 (a) On the date of the issuance of each Letter of Credit (and
with respect to the letters of credit previously issued under the Credit
Agreement described in Recital A, on the Closing Date), the Issuing Lender shall
be deemed irrevocably and unconditionally



                                       56
<PAGE>   57



to have sold and transferred to each Lender (other than the Issuing Lender) and
each Lender shall be deemed to have irrevocably and unconditionally purchased
and received from the Issuing Lender, an undivided interest and participation,
to the extent of such Lender's Commitment Percentage in effect from time to
time, in such Letter of Credit and all Letter of Credit Liability with respect
thereto. The Revolving Commitment of each Lender hereunder shall include that
Lender's share of the Letter of Credit Liability.

                 (b) In the event that any reimbursement obligation under this
Agreement is not paid when due to the Issuing Lender with respect to any Letter
of Credit, the Issuing Lender shall promptly notify the Agent to that effect,
and the Agent shall promptly notify each Lender (other than the Issuing Lender)
of the amount of such reimbursement obligation and each Lender other than the
Issuing Lender shall immediately pay to the Agent for distribution to the
Issuing Lender, in lawful money of the United States and in same day funds, an
amount equal to such Lender's Commitment Percentage then in effect of the amount
of such unpaid reimbursement obligation.

                 (c) The obligation of each Lender other than the Issuing Lender
to make payments under subsection (b) above shall be unconditional and
irrevocable and shall be made under all circumstances, including, without
limitation, following the occurrence of any Default or any Event of Default or
any of the circumstances referred to in Section 2.1(a)(ii) hereof.

                 (d) Prior to the occurrence of any Event of Default, the Agent
shall promptly distribute to each Lender its Commitment Percentage (or other
applicable share as expressly provided herein) of all amounts received on
account of the obligations of Borrower to repay amounts drawn under any Letter
of Credit (in like funds as received). Following the occurrence of an Event of
Default, all amounts received by the Agent on account of such obligations shall
be disbursed by the Agent as follows:

                          (i) First, to the payment of expenses incurred by the
Agent in the performance of its duties and enforcement of its rights under the
Loan Documents, including, without limitation, all costs and expenses of
collection, attorneys' fees, court costs and foreclosure expenses;

                          (ii) Then, to the Lenders, pro rata in accordance with
their respective Commitment Percentages until all outstanding reimbursement
obligations for drawings on such Letter of Credit and interest accrued thereon
have been paid in full; and




                                       57
<PAGE>   58



                          (iii) Then, and if but only if there remains any
available amount which has not been drawn under such Letter of Credit, to the
Agent to hold as cash collateral for the obligation of Borrower to reimburse any
future drawings on such Letter of Credit, Borrower hereby granting to the Agent,
for the pro rata, pari passu benefit of the Lenders, a security interest therein
which will be of first priority and hereby irrevocably agreeing that amounts so
held may be applied from time to time in reimbursement of drawings on such
Letter of Credit as the same may occur, until the expiration of such Letter of
Credit and payment in full of all amounts due with respect to any drawing
thereon.

                 (e) If any payment received from Borrower on account of any
reimbursement obligation with respect to any Letter of Credit and distributed
to a Lender under Section 2.16(d) hereof is thereafter recovered from the
Issuing Lender, each Lender which received such distribution shall, upon demand
by the Agent, repay to the Issuing Lender such Lender's ratable share of the
amount so recovered together with an amount equal to such Lender's ratable share
(according to the proportion of (i) the amount of such Lender's required
repayment to (ii) the total amount so recovered) of any interest of other amount
paid or payable by the Issuing Lender in respect of the total amount so
recovered.


                                   ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

                 3.1      TAXES.

                 (a) Subject to Section 3.1(g), all payments by Borrower to
Agent or the Lenders under this Agreement will be made free and clear of the
following (collectively, "Taxes"), and without deduction or withholding for, any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding such taxes
(including income taxes or franchise taxes) as are imposed on or measured by the
recipient's net income by the jurisdiction under the laws of which the recipient
is organized or maintains a Lending Office, or otherwise does business, or any
political subdivision thereof.

                 (b) In addition, Borrower shall pay any present or future stamp

any other Loan Documents (collectively, "Other Taxes").



                                       58
<PAGE>   59




                 (c) Borrower shall indemnify and hold harmless the Agent and
each Lender for the full amount of Taxes or Other Taxes (including any Taxes or
Other Taxes imposed by any jurisdiction on amounts payable under this Section
3.1) paid by the Agent or such Lender and any liability (including penalties,
interest, additions to tax and expenses) arising therefrom or with respect
thereto, whether or not such Taxes or Other Taxes were correctly or legally
asserted unless and except to the extent any such Taxes or Other Taxes were
imposed solely as a result of the gross negligence or willful misconduct of
Agent or such Lender. Payment under this indemnification shall be made within
thirty (30) days from the date the Agent or any Lender makes written demand
therefor.

                 (d) If Borrower shall be required by law to deduct or withhold
any Taxes or Other Taxes from or in respect of any sum payable hereunder to the
Agent or any Lender, then, subject to Section 3.1(g):

                          (i) the sum payable shall be increased as necessary so
that, after making all required deductions (including deductions applicable to
additional sums payable under this Section 3.1) the Agent or such Lender, as the
case may be, receives an amount equal to the sum it would have received had no
such deductions been made;

                          (ii) Borrower shall make such deductions; and

                          (iii) Borrower shall pay the full amount deducted to
the relevant taxation authority or other authority in accordance with applicable
law.

                 (e) Within 30 days after the date of any payment by Borrower of
Taxes or Other Taxes, Borrower shall furnish to the Agent the original or a
certified copy of a receipt evidencing payment thereof, or other evidence of
payment satisfactory to the Agent.

                 (f) Each Lender which is a foreign Person (i.e., a Person other
than a United States Person for United States Federal income tax purposes)
agrees that:

                          (i) such Lender shall, no later than the Closing Date

entitled to receive payments of principal, interest and fees under this
Agreement free from withholding of United States Federal income tax;

                          (ii) if at any time such Lender makes any changes
necessitating a new form, such Lender shall with reasonable promptness deliver
to Borrower through the Agent in replacement for, or in addition to, the forms
previously delivered by such Lender hereunder, two (2) accurate and complete
signed originals of Form 4224, or two (2) accurate and complete signed originals
of Form 1001, as appropriate, in each case indicating that such Lender is on the
date of delivery thereof entitled to receive payments of principal, interest and
fees under this Agreement free from withholding of United States Federal income
tax;

                          (iii) such Lender shall, before or promptly after the
occurrence of any event (including the passing of time but excluding any event
mentioned in (ii) above) requiring a change in or renewal of the most recent
Form 4224 or Form 1001 previously delivered by such Lender, deliver to Borrower
through the Agent two (2) accurate and complete original signed copies of Form
4224 or Form 1001, as appropriate, in replacement of the forms previously
delivered by such Lender; and

                          (iv) such Lender shall, promptly upon Borrower's
reasonable request to that effect, deliver to Borrower such other forms or
similar documentation as may be required from time to time by any applicable
law, treaty, rule or regulation in order to establish such Lender's tax status
for withholding purposes.

                 (g) Borrower shall not be required to pay any additional
amounts in respect of United States Federal or state income tax pursuant to
Section 3.1(d) to any Lender or any duly appointed assignee for the account of
any Lending Office of such Lender or assignee:

                          (i) if the obligation to pay such additional amounts
arises as a result of a failure by such Lender or assignee to comply with its
obligations under Section 3.1(f) in respect of such Lending Office;

                          (ii) if such Lender or assignee shall have delivered
to Borrower a Form 4224 in respect of such Lending Office pursuant to Section
3.1(f), and such Lender or assignee shall not at any time be entitled to
exemption from deduction or withholding of United States Federal income tax in
respect of payments by Borrower hereunder for any reason other than a change in
United States law or regulations or in the official interpretation of such law
or regulations by any governmental authority charged with the interpretation or
administration thereof (whether or not having the force of law) after the date
of delivery of such Form 4224; or




                                       60
<PAGE>   61




                          (iii) if such Lender or assignee shall have delivered
to Borrower a Form 1001 in respect of such Lending Office pursuant to Section
3.1(f), and such Lender or assignee shall not at any time be entitled to
reduction, partial exemption or exemption from deduction or withholding of
United States federal income tax in respect of payments by Borrower hereunder
for the account of such Lending Office for any reason other than a change in
United States law or regulations or any applicable tax treaty or regulations or
in the official interpretation of such law, treaty or regulations by any
governmental authority charged with the interpretation or administration thereof
(whether or not having the force of law) after the date of delivery of such Form
1001.

                 (h) If, at any time, Borrower requests any Lender to deliver
any forms or other documentation pursuant to Section 3.1(f)(iv), then Borrower
shall, on demand of such Lender, through the Agent reimburse such Lender for any
costs and expenses (including Attorney Costs) reasonably incurred by such Lender
in the preparation or delivery of such forms or other documentation.

                 (i) If Borrower is required to pay additional amounts to the
Agent or any Lender pursuant to Section 3.1(d), then such Lender shall use its
reasonable best efforts (consistent with legal and regulatory restrictions) to
change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by Borrower which may thereafter accrue if such change in the
judgment of such Lender is not otherwise disadvantageous to such Lender.

                 3.2 ILLEGALITY.

                 (a) If any Lender shall determine that the introduction of any
Requirement of Law or any change therein or in the interpretation or
administration thereof has made it unlawful, or that any central bank or other
Governmental Authority has asserted that it is unlawful, for such Lender or its
Lending Office to make LIBOR Loans, then, on notice thereof by such Lender to
Borrower through the Agent, the obligation of such Lender to make LIBOR Loans
shall be suspended until such Lender shall have notified the Agent and Borrower
that the circumstances giving rise to such determination no longer exist.

                 (b) If any Lender shall reasonably determine that it is
unlawful to maintain any LIBOR Loan, Borrower shall notify Lender that Borrower
shall either (i) prepay in full all LIBOR Loans of such lender then outstanding,
together with interest accrued thereon, or (ii) elect to convert in accordance
with Section 2.4 all LIBOR Loans then outstanding, after payment to such Lender
of all interest accrued thereon, into Base Rate Loans, either on the



                                       61
<PAGE>   62



last day of the Interest Period thereof if such Lender may lawfully continue to
maintain such LIBOR Loans to such day, or immediately if such Lender may not
lawfully continue to maintain such LIBOR Loans, together with any amounts
required to be paid in connection therewith pursuant to Section 3.4.

                 (c) If the obligation of any Lender to make or maintain LIBOR
Loans has been terminated, Borrower may elect, by giving notice to such Lender
through the Agent, that all Loans which would otherwise be made by such Lender
as LIBOR Loans shall instead be made as Base Rate Loans.

                 3.3 INCREASED COSTS AND REDUCTION OF RETURN.

                 (a) If any Lender shall determine that, due to either (i) the
introduction of or any change in or in the interpretation of any Requirement of
Law or (ii) the compliance with any guideline or request from any central bank
or other Governmental Authority (whether or not having the force of law), there
shall be any increase in the cost to such Lender of agreeing to make or of
making, funding or maintaining any LIBOR Loans hereunder, then Borrower shall be
liable for, and shall from time to time, upon written demand therefor by such
Lender (with a copy of such demand to the Agent), which demand shall set forth
the basis of such increased cost in reasonable detail, pay to the Agent for the
account of such Lender, such additional amounts as are sufficient to compensate
such Lender for such increased costs.

                 (b) If any Lender shall have reasonably determined that (i) the
introduction of any Capital Adequacy Regulation, (ii) any change in any Capital
Adequacy Regulation, (iii) any change in the interpretation or administration of
any Capital Adequacy Regulation by any central bank or other Governmental
Authority charged with the interpretation or administration thereof, or (iv)
compliance with any Capital Adequacy Regulation by such Lender (or its Lending
Office) or any corporation controlling such Lender, effects or would effect an
increase in the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy
and such Lender's desired return on capital), then, upon written demand of such
Lender (with a copy to the Agent), which demand shall set forth in reasonable
detail the basis for any such increase in required capital, Borrower shall
immediately pay to such Lender, from time to time as specified by such Lender,
additional amounts sufficient to compensate such Lender for such increase.

                 (c) If any Lender shall have determined that any of the events
described in Section 3.3(a) or Section 3.3(b) effects or would effect an
increase in cost or reduction of



                                       62
<PAGE>   63



return resulting in additional Obligations hereunder, such Lender shall, with
reasonable promptness, notify Borrower and the Agent of such determination,
provided that no failure to do so shall relieve Borrower of any Obligation
hereunder.

                 3.4 FUNDING LOSSES. Borrower agrees to reimburse each Lender
for, and to hold each Lender harmless from, any loss or expense that such Lender
sustains or incurs as a consequence of:

                 (a) the failure of Borrower to make any required payment or
prepayment of principal of any LIBOR Loan or Base Rate Loan (including payments
to be made after any acceleration thereof);

                 (b) the failure of Borrower to borrow, continue or convert a
Loan after Borrower has given (or is deemed to have given) a Borrowing Notice or
a Conversion/Continuation Notice;

                 (c) the failure of Borrower to make any prepayment after
Borrower has given a notice in accordance with Section 2.5;

                 (d) the prepayment of a LIBOR Loan on a day which is not the
last day of the Interest Period with respect thereto; or

                 (e) the conversion of any LIBOR Loan to a Base Rate Loan on a
day that is not the last day of the Interest Period with respect thereto;

such amount or amounts to include an amount equal to the excess, if any, of (a)
the amount of interest that would have accrued on the amount not paid, not
borrowed, not prepaid, prepaid, or converted for the period from the date of
such failure to pay, failure to borrow, failure to prepay, prepayment, or
conversion to the last day of then current Interest Period (or in the case of a
failure to borrow, the Interest Period which would have commenced on the date of
such failure) at the interest rate applicable to that LIBOR Loan, over (b) the
amount of interest that would accrue to the Lender on such amount at the LIBO
Rate in effect on such date by placing such amount on deposit for a comparable
period with leading lenders in the London interbank market.

                 3.5 INABILITY TO DETERMINE RATES. If the Agent shall have
determined that for any reason adequate and reasonable means do not exist for
ascertaining the LIBO Rate for any requested Interest Period with respect to a
proposed LIBOR Loan or that the LIBO Rate applicable pursuant to Section 2.9(a)
for any requested Interest Period with respect to



                                       63
<PAGE>   64



a proposed LIBOR Loan does not adequately and fairly reflect the cost to Lenders
of funding such Loan, the Agent will forthwith give notice of such determination
to Borrower and each Lender. Thereafter, the obligation of the Lenders to make
or maintain LIBOR Loans hereunder shall be suspended until the Agent revokes
such notice in writing. Upon receipt of such notice, Borrower may revoke any
Borrowing Notice or Conversion/Continuation Notice then submitted by it. If
Borrower does not revoke such notice, the Lenders shall make, convert or
continue the Loans, as proposed by Borrower, in the amount specified in the
applicable notice submitted by Borrower, but such Loans shall be made, converted
or continued as Base Rate Loans instead of LIBOR Loans.

                 3.6 CERTIFICATES OF LENDERS. Any Lender claiming reimbursement
or compensation pursuant to this Article III shall deliver to Borrower (with a
copy to the Agent) a certificate setting forth in reasonable detail a summary of
the basis of such demand and the amount payable to such Lender hereunder.

                 3.7 SURVIVAL. The agreements and obligations of Borrower in
this Article III shall survive the payment of all other obligations.

                 5.11  ENVIRONMENTAL MATTERS.

                 (a) Environmental Laws. Except as disclosed in Schedule 5.11 or
in the SEC Report, the operations and Properties of Borrower, the REIT, the
Management Entities and their Subsidiaries comply in all respects with all
Environmental Laws, except such non-compliance affecting (i) any Property in the
Unencumbered Asset Pool as would not (if enforced in accordance with
Environmental Laws) result in liability in excess of 10% of the value of such
Property or (ii) all other Properties as would not result in liability which
could reasonably be expected to result in a Material Adverse Effect.

                 (b) Environmental Permits. Except as described in Schedule 5.11
or in the SEC Report, Borrower, the REIT, the Management Entities and their
Subsidiaries have obtained and maintained all material licenses, permits,
authorizations and registrations required under any Environmental Law
("Environmental Permits"). All such Environmental Permits are in good standing,
and each such Person is in compliance with all terms and conditions thereof,
except, with respect to Persons that are not Designated Entities, where the
failure to be in compliance could reasonably be expected to have a Material
Adverse Effect.

                 (c) Orders. Except as specifically disclosed in Schedule 5.11
or in the SEC Report, there are no outstanding written orders from or agreements
with any Governmental Authority nor any judicial or docketed administrative
proceedings respecting any Environmental Law, Environmental Claim or Hazardous
Material to which Borrower, the REIT, any Management Entity, any of their
Subsidiaries, or any of such Person's Properties or operations, is subject with
respect to any Unencumbered Asset Pool Property, or with respect to any other
Property that could reasonably be expected to have a Material Adverse Effect.

                 (d) Hazardous Materials. Except as disclosed in Schedule 5.11
or in the SEC Report, there are no Hazardous Materials or other conditions or
circumstances existing with respect to any Property, or arising from operations
prior to the Closing Date, that would reasonably be expected to give rise to
Environmental Claims for any such condition, circumstance or Property with
respect to any Unencumbered Asset Pool Property, or with respect to any other
Property, that could reasonably be expected to have a Material Adverse



                                       74
<PAGE>   75



Effect. In addition, (i) there are not located on the Properties underground
storage tanks (x) that are not properly registered or permitted under applicable
Environmental Laws, or (y) that are leaking or emitting Hazardous Materials
whether on-or off-site, and (ii) Borrower, the REIT, the Management Entities and
their Subsidiaries have notified all of their employees of the existence, if
any, of any health hazard arising from the conditions of their employment to the
extent required under any Environmental Laws and have met all notification
requirements under Title III of CERCLA and all other Environmental Laws, in each
case with respect to any Unencumbered Asset Pool Property, or with respect to
any other Property that could reasonably be expected to have a Material Adverse
Effect.

                 5.12 REGULATED ENTITIES. None of Borrower, the REIT, any
Management Entity, or any of their Subsidiaries is (a) an "investment company"
within the meaning of the Investment Company Act of 1940; or (b) subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act, any state public utilities code, or any
other Federal or state statute or regulation limiting its ability to incur
Indebtedness.

                 5.13 USE OF PROCEEDS; MARGIN REGULATIONS. The proceeds of the
Loans are intended to be and shall be used solely for the purposes set forth in
and permitted by Sections 2.1(b) and Section 6.10, and are intended to be and

                 5.14 REIT AND TAX STATUS; STOCK EXCHANGE LISTING. The REIT
currently has REIT Status and has maintained REIT Status on a continuous basis
since its formation. Borrower is not an association taxable as a corporation
under the Code. The shares of common Stock of the REIT are listed on the NYSE.

                 5.15 INSURANCE. Borrower, the REIT, the Management Entities,
their Subsidiaries and the Properties are insured with financially sound and
reputable insurance companies, in such amounts, with such deductibles and
covering such risks as are customarily carried by companies engaged in similar
businesses and owning similar Properties in localities where Borrower and the
Management Entities operate.

                 5.16 NO DEFAULT. No Default or Event of Default exists or would
result from the incurring of any Obligations by Borrower. Neither Borrower, nor
the REIT, nor any Management Entity, nor any of their Subsidiaries is in default
under or with respect to any Contractual Obligation in any respect which,
individually or together with all such other defaults, would reasonably be
expected to have a Material Adverse Effect.

                 5.17 FULL DISCLOSURE. None of the representations or warranties
made by Borrower, the REIT, the Management Entity or any Subsidiary in the Loan
Documents as of the date such representations and warranties are made or deemed
made, and none of the statements contained in each exhibit, report, statement or
certificate furnished by or on behalf of any such Person in connection with the
Loan Documents, contains any untrue statement of a material fact or omits any
material fact required to be stated therein or necessary to make the statements
made therein, in light of the circumstances under which they are made, not
misleading. There is no fact, to the Knowledge of Borrower, which materially and
adversely affects the business, operations, properties, assets or condition
(financial or otherwise) of Borrower, the REIT, the Management Entities, and the
Subsidiaries, taken as a whole, that has not been disclosed herein, in the SEC
Reports, or in other documents, certificates and statements furnished to the
Agent and each Lender hereunder or pursuant hereto. The copies of all documents
delivered to the Agent and/or the Lenders from time to time in connection with
this Agreement are and shall be true and complete copies of the originals
thereof and have not been or shall not be amended except as disclosed to the
Agent and/or the Lenders, as applicable.

                 5.18 NOT A "FOREIGN PERSON." Neither Borrower nor any
Wholly-Owned Subsidiary which owns a Property in the Unencumbered Asset Pool is
a "foreign person" within the meaning of Section 1445(f)(3) of the Code.

                 5.19 DEFECTS. Except as disclosed to and approved in writing by
the Requisite Lenders, to the Knowledge of Borrower, there exist no material
defects that would make any Property in the Unencumbered Asset Pool unsuitable
for the present or contemplated use thereof. Except as disclosed to and approved
in writing by the Requisite Lenders, to the Knowledge of Borrower, there are no
abnormal hazards, including but not limited to earth movement or slippage,
affecting any Property in the Unencumbered Asset Pool.

                 5.20 PROPERTY DOCUMENTS. Prior to including any Property in the
Unencumbered Asset Pool, Borrower has delivered to the Agent, copies of all
easement agreements, reciprocal easement agreements, management agreements,
service contracts, and other agreements, instruments and documents and all
amendments thereof (whether or not recorded) which affect in any material
respect such Property (except apartment leases).

                 5.21 CONDEMNATION. No condemnation proceeding involving any
Property in the Unencumbered Asset Pool or any portion thereof or parking
facility used in connection therewith has been commenced or, to the Knowledge of
Borrower, is contemplated by any Governmental Authority, nor has any portion of
any Property in the Unencumbered Asset



                                       76
<PAGE>   77



Pool or any parking facility used in connection therewith been damaged due to
fire or other casualty.

                 5.22 VIOLATION OF LAWS; PERMITS. None of the Properties in the
Unencumbered Asset Pool are being operated in violation of (a) any Requirements
of Law or (b) any building permits, restrictions of record, or any agreement
affecting any such property or part thereof, or (c) any judgment, decree or
order applicable to such property. To the Knowledge of Borrower, all
governmental permits (including, without limitation, building permits and
certificates of occupancy) necessary under applicable Requirements of Law to
lawfully construct, own, lease, occupy, use and operate each Property in the
Unencumbered Asset Pool and the improvements thereon, including, but not limited
to, all applicable zoning laws, ordinances and regulations, have been obtained.

                 5.23 UTILITIES. Each Property in the Unencumbered Asset Pool
has adequate water, gas, telephone, electrical supply, storm and sanitary
sewerage facilities and means of access to and from public streets or highways.

                 5.24 LEASES. Except for apartment leases and other Permitted
Exceptions, there are no leases affecting any Property in the Unencumbered Asset
Pool. No rent has been collected more than one month in advance under any such
apartment lease for a Property in the Unencumbered Asset Pool other than in the
Ordinary Course of Business. No such lease or any interest therein is subject to
any present assignment or pledge. All rent due to date under each such lease has
been collected in the Ordinary Course of Business and no concession has been
granted to any lessee in the form of a waiver, release, reduction, discount or
other alteration of rent due or to become due, other than in the Ordinary Course
of Business. The interest of the lessee under each such lease is as lessee only,
with no options to purchase or rights of first refusal.

                 5.25 YEAR 2000 COMPLIANCE. Borrower has conducted a
comprehensive review and assessment of its computers systems and applications
and made inquiry of Borrower's key suppliers and vendors with respect to the
so-called "year 2000 problem" (the risk that computer applications may not be
able to properly perform date-sensitive functions after December 31, 1999) and,
based on that review and inquiry, Borrower does not believe that the "year 2000
problem" will result in a material adverse change in the ability of Borrower and
its Subsidiaries to manage and operate their properties and pay and perform
their obligations hereunder.

                 5.26 NON-GUARANTOR SUBSIDIARIES. All of the Wholly-Owned
Subsidiaries of the REIT, other than those listed on Schedule 5.26 and their
non-corporate Subsidiaries



                                       77
<PAGE>   78



(each a "Non-Guarantor Subsidiary," and collectively, the "Non-Guarantor
Subsidiaries"), are Guarantor Subsidiaries. The Non-Guarantor Subsidiaries
collectively have a net worth, calculated in accordance with GAAP (which may be
less than fair market value), that is less than $10,000,000. The Borrower
currently expects that the assets of the Non-Guarantor Subsidiaries shall be
transferred from the REIT to the Borrower as soon as practicable, consistent
with relevant legal requirements, with prudent business practices and with
Contractual Obligations, and that the Non-Guarantor Subsidiaries may be
dissolved and liquidated.

                 5.27 PALENCIA BOND. Ambassador X, L.P. is the sole owner of the
Palencia Bond. The Palencia Bond is not encumbered by any Liens other than the
Lien of that certain Pledge and Security Agreement dated as of April 16, 1998 by
and between Ambassador X, L.P. and Borrower, as in effect on the date hereof.
Notwithstanding Section 5.6, the Liens on the Palencia Property existing on the
date hereof constitute Permitted Liens.

that may be discovered therein or in any Loan Document or in the execution,
acknowledgment or recordation thereof.

of another Subsidiary if such transaction would result in a violation of any
covenant in this Agreement.

<PAGE>   105


payment terms of any Intra-Company Debt is entered into without the prior

                 8.2 REMEDIES.

                 If any Event of Default occurs, the Agent shall, at the request
of, or may, with the consent of, the Requisite Lenders:

                 (a) Termination of Commitment.  Declare the Commitment of 
each Lender to make Loans to be terminated, whereupon such Commitments shall
forthwith be terminated;

                 (b) Acceleration. Declare (i) the unpaid principal amount of
all outstanding Loans and all interest accrued and unpaid thereon, and (ii) all
other amounts owing or payable hereunder or under any other Loan Document to be
immediately due and payable, without presentment, demand, protest or other
notice of any kind, all of which are hereby expressly waived;

                 (c) Obligations under Letters of Credit. Declare forthwith due
and payable all obligations of Borrower with respect to the Letters of Credit,
including, without limitation, all unreimbursed drawings under the Letters of
Credit and the aggregate contingent obligation of Borrower to reimburse Agent
and Lenders for the available amount which could at any time be drawn under the
Letters of Credit (even if such amount is not then able to be drawn pursuant to
the terms of the Letters of Credit), without presentment, demand, protest,
notice of dishonor, notice of intent to demand or to accelerate payment, notice
of acceleration or notice of any other kind, all of which are hereby expressly
waived, and upon such declaration the same shall become immediately due and
payable, and Agent (upon the request or with the consent of Requisite Lenders)
may enforce all obligations of Borrower with respect to the Letters of Credit to
Agent and the Lenders under the Loan Documents and exercise any and all other
remedies granted to Agent and the Lenders at law, in equity or otherwise. In
addition, Agent (upon the request or with the consent of Requisite Lenders) may:
(i) exercise any remedy available to Agent or the Lenders under any Loan
Document; and/or (ii) take whatever action at law or in equity may appear
necessary or appropriate to collect any amount due or thereafter to become due
or to enforce performance






                                      105
<PAGE>   106


and observance of all Obligations of Borrower with respect to the Letters of
Credit. Any amounts delivered by Borrower on account of the aggregate contingent
obligation of Account Party to reimburse Lenders for the available amount which
could at any time be drawn under the Letters of Credit shall be held by the
Agent as cash collateral for the Obligations with respect to the Letters of
Credit; and

                 (d) Other Remedies. Exercise on behalf of itself and the
Lenders all rights and remedies available to it and the Lenders under the Loan
Documents or applicable law; provided, however, that upon the occurrence of any
event specified in Section 8.1(f) or 8.1(g) (in the case of clause (i) of
Section 8.1 (g) upon the expiration of the sixty (60)-day period mentioned
therein), the Commitment of each Lender to make Loans shall automatically
terminate, and the unpaid principal amount of all outstanding Loans and interest
accrued and unpaid thereon, and all other amounts owing or payable hereunder as
aforesaid shall automatically become due and payable without further act of any
Agent or Lender.

                 8.3 RIGHTS NOT EXCLUSIVE. The rights provided for in this
Agreement and the other Loan Documents are cumulative and are not exclusive of
any other rights, powers, privileges or remedies provided by law or in equity,
or under any other instrument, document or agreement now existing or hereafter
arising.

                                   ARTICLE IX

                                    THE AGENT

                 9.1 APPOINTMENT AND AUTHORIZATION. Each Lender hereby
irrevocably appoints, designates and authorizes the Agent to take such action on
its behalf under the provisions of this Agreement and each other Loan Document
and to exercise such powers and perform such duties as are expressly delegated
to it by the terms of this Agreement or any other Loan Document, together with
such powers as are reasonably incidental thereto. Notwithstanding any provision
to the contrary contained elsewhere in this Agreement or in any other Loan
Document, Agent shall not have any duties or responsibilities except those
expressly set forth herein, nor shall Agent have or be deemed to have any
fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist on the part of Agent.
Notwithstanding anything to the contrary herein, Issuing Lender shall act on
behalf of the Lenders with respect to the Letters of Credit (and all conditions
precedent applicable to the issuance or extension thereof), until such time and
except for so long as the Agent may elect to act for the Issuing Lender with
respect thereto; provided, however, that the Issuing Lender shall have all of
the benefits and immunities (i)






                                      106
<PAGE>   107


for acts taken or omissions suffered by the Issuing Lender in connection with
Letters of Credit as fully as if the term "Agent", as used in this Article IX,
included the Issuing Lender with respect to such acts or omissions, and (ii) as
additionally provided in this Agreement with respect to the Issuing Lender.

                 9.2 DELEGATION OF DUTIES. The Agent may execute any of its
duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Agent shall not be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects with reasonable care.

                 9.3 LIABILITY OF AGENT. The Agent, its respective Affiliates,
or their respective officers, directors, employees, agents, or attorneys-in-fact
(all of the foregoing being collectively referred to as the "Agent-Related
Persons") shall not (a) be liable for any action taken or omitted to be taken by
any of them under or in connection with this Agreement or any other Loan
Document (except for its own gross negligence or willful misconduct), or (b) be
responsible in any manner to any of the Lenders for any recital, statement,
representation or warranty made by Borrower, the REIT, any Management Entity or
Subsidiary or any Affiliate of any such Person, or any officer thereof,
contained in this Agreement or in any other Loan Document, or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in connection with, this Agreement or any
other Loan Document, or for the value of any property in the Unencumbered Asset
Pool or the validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement, any other Loan Document, or for any failure of Borrower, the
REIT or any other party to any Loan Document to perform its obligations
hereunder or thereunder. No Agent-Related Person shall be under any obligation
to any Lender to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, or to inspect the Properties, books or records of Borrower,
the REIT, any Management Entity or Subsidiary or Affiliates thereof.

                 9.4 RELIANCE BY AGENT.

                 (a) Generally.  The Agent shall be entitled to rely, and 
shall be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, telegram, telecopy, telex or telephone
message, statement or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons, and upon advice and statements of legal counsel (including counsel
to Borrower), independent accountants and other experts selected by the Agent.
The Agent






                                      107
<PAGE>   108


shall be fully justified in failing or refusing to take any action under this
Agreement or any other Loan Document unless it shall first receive such advice
or concurrence of the Requisite Lenders as it deems appropriate and, if it so
requests, it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refinancing from acting, under this Agreement
or any other Loan Document in accordance with a request or consent of the
Requisite Lenders, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all of the Lenders.

                 9.5 CONDITIONS PRECEDENT. For purposes of determining
compliance with the conditions specified in Sections 4.1 and 4.2 (as to the
initial borrowing hereunder), each Lender that has executed this Agreement shall
be deemed to have consented to, approved or accepted or to be satisfied with
each document or other matter required thereunder to be consented to or approved
by or acceptable or satisfactory to such Lender, unless an officer of the Agent
responsible for the transactions contemplated by the Loan Documents shall have
received notice from such Lender prior to the initial borrowing specifying its
objection thereto and either such objection shall not have been withdrawn by
notice to the Agent to that effect or such Lender shall not have made available
to the Agent the Lender's ratable portion of such borrowing.

                 9.6 NOTICE OF DEFAULT. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default, except
with respect to defaults in the payment of principal, interest and fees required
to be paid to the Agent for the account of the Lenders, unless the Agent shall
have received written notice from a Lender or Borrower referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default." In the event that the Agent receives such a
notice, the Agent shall give notice thereof to the Lenders. The Agent shall take
such action with respect to such Default or Event of Default as shall be
requested by the Requisite Lenders in accordance with Article VIII; provided,
however, that unless and until the Agent shall have received any such request,
it may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Default or Event of Default as it shall deem
advisable or in the best interest of the Lenders.

                 9.7 CREDIT DECISION. Each Lender expressly acknowledges that
none of the Agent-Related Persons has made any representation or warranty to
such Lender and that no act by the Agent hereinafter taken, including any review
of the affairs of Borrower, the REIT, any Management Entity or Subsidiary, shall
be deemed to constitute any representation or warranty by the Agent to any
Lender. Each Lender represents to the Agent that such






                                      108
<PAGE>   109


Lender has, independently and without reliance upon the Agent and based on such
documents and information as such Lender has deemed appropriate, made its own
appraisal of and investigation into the business, prospects, operations,
Properties, financial and other condition and creditworthiness of Borrower, the
REIT, any Management Entity or Subsidiary, and all applicable lender regulatory
laws relating to the transactions contemplated thereby, and made its own
decision to enter into this Agreement and extend credit to Borrower hereunder.
Each Lender also represents that it will, independently and without reliance
upon the Agent and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement and the other
Loan Documents, and to make such investigations as it deems necessary to inform
itself as to the business, prospects, operations, Properties, financial and
other condition and creditworthiness of Borrower, the REIT, the Management
Entities and the Subsidiaries. Except for notices, reports and other documents
expressly herein required to be furnished to the Lenders by the Agent, Agent
shall have no duty or responsibility to provide any Lender with any credit or
other information concerning the business, prospects, operations, Properties,
financial and other condition or creditworthiness of Borrower, the REIT, the
Management Entities and the Subsidiaries which may come into the possession of
any of the Agent-Related Persons.

                 9.8 INDEMNIFICATION. The Lenders shall indemnify upon demand
the Agent Related Persons (to the extent not reimbursed by or on behalf of
Borrower and without limiting the obligation of Borrower to do so) ratably from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses and disbursements of any kind
whatsoever which may at any time (including at any time following the repayment
of the Loans) be imposed on, incurred by or asserted against any such Person in
any way relating to or arising out of this Agreement or any document
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by any such Person
under or in connection with any of the foregoing; provided, however, that no
Lender shall be liable for the payment to the Agent-Related Persons of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting solely from such
Person's gross negligence or willful misconduct. Without limitation of the
foregoing, each Lender shall reimburse the Agent upon demand (to the extent the
Agent is not reimbursed upon demand by Borrower, unless the Agent is legally
restricted from making such demand upon Borrower, in which case demand need not
be made upon Borrower) for its ratable share of any costs or out-of-pocket
expenses (including Attorney Costs) incurred by the Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement,






                                      109
<PAGE>   110


any other Loan Document, or any document contemplated by or referred to herein
to the extent that the Agent is not reimbursed for such expenses by or on behalf
of Borrower. Without limiting the generality of the foregoing, if the IRS or any
authority of the United States or other jurisdiction asserts a claim that the
Agent did not properly withhold tax from amounts paid to or for the account of
any Lender (because the appropriate form was not delivered or was not properly
executed, or because such Lender failed to notify the Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding
tax ineffective, or for any other reason), such Lender shall indemnify the Agent
fully for all amounts paid, directly or indirectly, by the Agent as tax or
otherwise, including penalties and interest, and including any taxes imposed by
any jurisdiction on the amounts payable to the Agent under this Section 9.7,
together with all costs, expenses and attorneys' fees (including allocated costs
for in-house legal services). The obligation of the Lenders in this Section
shall survive the payment of all Obligations.

                 9.9 AGENT IN INDIVIDUAL CAPACITY. BofA (and any other Lender
that may hereafter serve as Agent) and each of their respective Affiliates may
make loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory or other business with, Borrower, the REIT, the Management
Entities and the Subsidiaries and Affiliates as though BofA (or any other such
Lender) were not the agent hereunder and without notice to the Lenders. With
respect to its Loans, BofA (and any other Lender that may hereafter serve as
Agent), shall have the same rights and powers under this Agreement as any other
Lender and may exercise the same as though each of them were not an agent, and
the terms "Lender" and "Lenders" shall include BofA (and any other Lender that
may hereafter serve as Agent), in its individual capacity.

                 9.10 SUCCESSOR AGENTS. The Agent may resign as Agent upon 30
days' notice to the Lenders. The Requisite Lenders may at any time remove the
Agent by written notice to that effect to be effective on such date as the
Requisite Lenders designate. If the Agent shall resign or be removed under this
Agreement, the Requisite Lenders shall appoint from among the Lenders a
successor Agent for the Lenders, which successor Agent shall, if no Default or
Event of Default exists hereunder, be subject to the approval of Borrower, which
approval shall not be unreasonably withheld. If no successor Agent is appointed
prior to the effective date of the resignation of the retiring Agent, the
retiring Agent shall appoint, after consulting with the Lenders and Borrower, a
successor Agent. Upon the acceptance of its appointment as successor Agent
hereunder, such successor Agent shall succeed to all the rights, powers and
duties of the retiring Agent, and the term "Agent" shall mean such successor
Agent, and the retiring Agent's rights, powers and duties as Agent shall be
terminated. After any retiring Agent's resignation hereunder as Agent, the
provisions of this






                                      110
<PAGE>   111


Article IX and Sections 10.4 and 10.5 shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was an Agent under this
Agreement.

same is in writing and signed by the Agent.

                 10.2     NOTICES.

                 (a) Delivery. All notices, requests and other communications
provided for hereunder shall be in writing (including, unless the context
expressly otherwise provides, telegraphic, telex, facsimile transmission or
cable communication) and mailed, telegraphed, telexed or delivered, (i) if to
Borrower, to its address specified on the signature pages hereof, (ii) if to any
Lender, to its Domestic Lending Office, and (iii) if to Agent, to its address
specified on the signature pages hereof; or, as to Borrower or the Agent, to
such other address as shall be designated by such party in a written notice to
the other parties, and as to each other party, at such other address as shall be
designated by such party in a written notice to Borrower and the Agent.

except that notices pursuant to Article II or VIII shall not be effective until
actually received by the Agent.

                 (c) Reliance. Borrower acknowledges and agrees that any
agreement of the Agent and the Lenders under Article II to receive certain
notices by telephone and facsimile is solely for the convenience and at the
request of Borrower. The Agent and the Lenders shall be entitled to rely on the
authority of any Person purporting to be a Person authorized by Borrower to give
such notice, and the Agent and the Lenders shall not have any liability to
Borrower or any other Person on account of any action taken or not taken by






                                      112
<PAGE>   113


the Agent and the Lenders in reliance upon such telephonic or facsimile notice.
The obligation of Borrower to repay the Loans shall not be affected in any way
or to any extent by any failure by the Agent and the Lenders to receive written
confirmation of any telephonic or facsimile notice or the receipt by the Agent
and the Lenders of a confirmation which is at variance with the terms understood
by the Agent and the Lenders to be contained in the telephonic or facsimile
notice.

                 10.3 NO WAIVER; CUMULATIVE REMEDIES. No failure to exercise and
no delay in exercising, on the part of any Agent or Lender, any right, remedy,
power or privilege hereunder, shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege.

                 10.4 COSTS AND EXPENSES. Borrower shall, whether or not the
transactions contemplated hereby shall be consummated:

                 (a) Facility Expenses. Pay or reimburse the Agent on demand for
all costs and expenses incurred in connection with the development, preparation
or delivery of, and any amendment, supplement, waiver or modification to, this
Agreement, any Loan Document and any other documents prepared in connection
herewith or therewith, the consummation of the transactions contemplated hereby
and thereby, and any proposal for additions to the Unencumbered Asset Pool
Properties, and the syndication of this Agreement to other Lenders, as well as
all costs of the Agent and the Issuing Lender in connection with the issuance of
Letters of Credit (including, without limitation, title insurance premiums and
charges, survey costs, recording costs and taxes, travel and due diligence
expenses incurred by representatives of the Agent, and the reasonable Attorney
Costs incurred by the Agent with respect thereto, and with respect to the
Letters of Credit, amendment fees, drawing fees, check fees, foreign currency
fees, and other fees and costs the Issuing Lender normally charges in connection
therewith);

                 (b) Enforcement Expenses. Pay or reimburse the Agent and
Lenders on demand for all reasonable costs and expenses incurred by them in
connection with the enforcement, attempted enforcement, or preservation of any
rights or remedies (including in connection with any "workout" or restructuring
regarding the Loans) under this Agreement, any other Loan Document, and any such
other documents, including reasonable Attorney Costs incurred by the Agent and
Lender; and

                 (c) Property Diligence Expenses.  Pay or reimburse the Agent 
on demand for all audits, environmental inspections and reviews (including
the allocated costs of such






                                      113
<PAGE>   114


internal services), search and filing costs, fees and expenses, incurred or
sustained by the Agent in connection with the matters referred to under
paragraphs (a) and (b) of this Section.

                 10.5 INDEMNITY. Borrower shall indemnify and hold harmless the
Agent, each Lender and each of their respective officers, directors, employees,
counsel, agents and attorneys-in-fact (each, an "Indemnified Person") from and
against and pay them for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, charges, expenses or disbursements
(including Attorney Costs) of any kind or nature whatsoever with respect to the
execution, delivery, enforcement, performance and administration of this
Agreement and any other Loan Documents, or the transactions contemplated hereby
and thereby, and with respect to any investigation, litigation or proceeding
related to this Agreement or the Loans or the use of the proceeds thereof,
whether or not any Indemnified Person is a party thereto (all the foregoing,
collectively, the "Indemnified Liabilities'); provided, that Borrower shall have
no obligation hereunder to any Indemnified Person with respect to Indemnified
Liabilities arising from the gross negligence or willful misconduct of such
Indemnified Person. The agreements in this Section 10.5 shall survive payment of
all other Obligations.

                 10.6 MARSHALLING; PAYMENTS SET ASIDE. Neither the Agent nor any
Lender shall be under any obligation to marshal any assets in favor of Borrower
or any other Person or against or in payment of any or all of the Obligations.
To the extent that Borrower makes a payment or payments to the Agent or any
Lender, or the Agent or any Lender enforces its Liens or exercises its rights of
setoff, and such payment or payments or the proceeds of such enforcement or
setoff or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to a trustee,
receiver or any other party in connection with any Insolvency Pending, or
otherwise, then to the extent of such recovery the obligation or part thereof
originally intended to be satisfied shall be revived and continued in full force
and effect as if such payment had not been made or such enforcement or setoff
had not occurred.

                 10.7 SUCCESSORS AND ASSIGNS. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that Borrower may not assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of the Agent and each Lender, which may be withheld in their
sole and absolute discretion.

                 10.8 ASSIGNMENTS, PARTICIPATIONS, ETC.







                                      114
<PAGE>   115


                 (a) Assignments. Subject to the further provisions of this
Section 10.8(a), any Lender may, with the written consent of the Agent, which
consent shall not be unreasonably withheld, at any time assign and delegate to
one or more Eligible Assignees (provided that no written consent of the Agent
shall be required in connection with any assignment and delegation by a Lender
to a Lender Affiliate of such Lender) (each an "Assignee") all, or any ratable
part of all, of the Loans, the Letter of Credit Liability, the Commitments and
the other rights and obligations of such Lender hereunder, in a minimum amount
of $5,000,000 and in additional increments of $250,000; provided, however, that
Borrower and the Agent may continue to deal solely and directly with such Lender
in connection with the interest so assigned to an Assignee until (A) written
notice of such assignment, together with payment instructions, addresses and
related information with respect to the Assignee, shall have been given to
Borrower and the Agent by such Lender and the Assignee; (B) such Lender and its
Assignee shall have delivered to Borrower and the Agent an Assignment and
Acceptance in the form of EXHIBIT K ("Assignment and Acceptance") together with
any Note or Notes subject to such assignment; (C) such Lender shall have paid to
the Agent, for its own account, an assignment fee in the amount of $1500, if the
Assignee is a Lender (without giving effect to the Assignment), and $3000 in all
other cases; and (D) such Lender shall have delivered to the Agent such
documents as may be required by Section 3.1(f). Any such assignment requiring
the approval of the Agent shall also require the approval of Borrower (such
approval not to be unreasonably withheld or delayed), provided that Borrower's
failure to approve or disapprove such assignment within five days' after
receiving written notice thereof shall be deemed approval by Borrower of such
assignment, and provided further, that no such approval from Borrower shall be
required during the continuation of a Default or Event of Default.

                 (b) Rights of Assignee. From and after the date that the Agent
notifies the assignor Lender that the Agent has received an executed Assignment
and Acceptance and payment of the assignment fee specified in Section 10.8(a),
(i) the Assignee thereunder shall, subject to Section 10.8(a), be a party hereto
and, to the extent that rights and obligations hereunder have been assigned to
it pursuant to such Assignment and Acceptance, shall have the rights and
obligations of a Lender under the Loan Documents, and (ii) the assignor Lender
shall, to the extent that rights and obligations hereunder have been assigned by
it pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under the Loan Documents.

                 (c) Replacement Notes. Within thirty (30) Business Days after
its receipt of notice by the Agent that the Agent has received an executed
Assignment and Acceptance and payment of the processing fee, Borrower shall
execute and deliver to the Agent, new Notes evidencing such Assignee's assigned
Loans and Commitment and, if the assignor






                                      115
<PAGE>   116


Lender has retained a portion of its Loans and its Commitment, replacement Notes
in the principal amount of the Loan retained by the assignor Lender (such Notes
to be in exchange for, but not in payment of, the Notes held by such Lender).
Immediately upon each Assignee's making its payment under the Assignment and
Acceptance, this Agreement shall be deemed to be amended to the extent, but only
to the extent, necessary to reflect the addition of the Assignee and the
resulting adjustment of the Commitments arising therefrom. The Commitment
allocated to each Assignee shall reduce such Commitment of the assigning Lender,
pro tanto.

                 (d) Participations. Any Lender may at any time sell to one or
more commercial lenders (a "Participant") participating interests in any Loans,
Letter of Credit Liability and Commitment of that Lender and the other interests
of that Lender (the "originating Lender") hereunder and under the other Loan
Documents; provided, however, that (i) the originating Lender's obligations
under this Agreement shall remain unchanged, (ii) the originating Lender shall
remain solely responsible for the performance of such obligations, (iii)
Borrower and the Agent shall continue to deal solely and directly with the
originating Lender in connection with the originating Lender's rights and
obligations under this Agreement and the other Loan Documents, (iv) no Lender
shall transfer or grant any participating interest under which the Participant
shall have rights to approve any amendment to, or any consent or waiver with
respect to, this Agreement or any other Loan Document, except to the extent such
amendment, consent or waiver would require unanimous consent as described in the
first proviso to Section 10.1; and (v) Borrower shall have approved the transfer
or grant of any participating interest in any Loan, Letter of Credit Liability
and Commitment of the originating Lender to a Participant that has not
theretofore previously held a participating interest therein (such approval not
to be unreasonably withheld or delayed), provided that Borrower's failure to
approve or disapprove in writing such Participant within five days' after
receiving written notice thereof shall be deemed approval by Borrower of such
transfer or grant to such Participant, and provided further, that no such
approval from Borrower shall be required during the continuation of a Default or
Event of Default. In the case of any such participation, the Participant shall
not have any rights under this Agreement, or any of the other Loan Documents,
and all amounts payable by Borrower hereunder shall be determined as if such
Lender had not sold such participation; except that, if amounts outstanding
under this Agreement are due and unpaid, or shall have been declared or shall
have become due and payable upon the occurrence of an Event of Default, each
Participant shall be deemed to have the right of setoff in respect of its
participating interest in amounts owing under this Agreement to the same extent
as if the amount of its participating interest were owing directly to it as a
Lender under this Agreement.







                                      116
<PAGE>   117


                 (e) Assignments to Federal Reserve Bank. Notwithstanding any
other provision contained in this Agreement or any other Loan Document to the
contrary, any Lender may assign all or any portion of the Loans or Notes held by
it to any Federal Reserve Bank or the United States Treasury as collateral
security pursuant to Regulation A of the Board of Governors of the Federal
Reserve System and any Operating Circular issued by such Federal Reserve Bank,
provided that any payment in respect of such assigned Loans or Notes made by
Borrower to or for the account of the assigning and/or pledging Lender in
accordance with the terms of this Agreement shall satisfy Borrower's obligations
hereunder in respect of such assigned Loans or Notes to the extent of such
payment. No such assignment shall release the assigning Lender from its
obligations hereunder.

                 10.9 SETOFF. In addition to any rights and remedies of the
Lenders provided by law, if an Event of Default exists, each Lender is
authorized at any time and from time to time, without prior notice to Borrower,
any such notice being waived by Borrower to the fullest extent permitted by law,
to set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held by, and other indebtedness at any time
owing to, such Lender to or for the credit or the account of Borrower against
any and all obligations owing to such Lender, now or hereafter existing,
irrespective of whether the Agent or such Lender shall have made demand under
this Agreement or any Loan Document and whether such obligations may be
contingent or unmatured. Each Lender agrees to promptly notify Borrower and the
Agent after any such setoff and application made by such Lender; provided,
however, that the failure to give such notice shall not affect the validity of
such setoff and application. The rights of each Lender under this Section 10.9
are in addition to the other rights and remedies (including other rights of
setoff) that such Lender may have. NOTWITHSTANDING THE FOREGOING, NO LENDER
SHALL EXERCISE, OR ATTEMPT TO EXERCISE, ANY RIGHT OF SETOFF, BANKER'S LIEN, OR
THE LIKE, AGAINST ANY DEPOSIT ACCOUNT OR PROPERTY OF BORROWER, THE REIT, ANY
MANAGEMENT ENTITY OR ANY SUBSIDIARY HELD OR MAINTAINED BY ANY LENDER, WITHOUT
THE PRIOR WRITTEN CONSENT OF THE REQUISITE LENDERS.

                 10.10 NOTIFICATION OF ADDRESSES, LENDING OFFICES, ETC. Each
Lender shall notify the Agent in writing of any changes in the address to which
notices to such Lender should be directed, of addresses of its Offshore Lending
Office, of payment instructions in respect of all payments to be made to it
hereunder and of such other administrative information as the Agent shall
reasonably request.

                 10.11 COUNTERPARTS. This Agreement may be executed by one or
more of the parties to this Agreement in any number of separate counterparts,
each of which, when






                                      117
<PAGE>   118


so executed, shall be deemed an original, and all of said counterparts taken
together shall be deemed to constitute but one and the same instrument. A set of
the copies of this Agreement signed by all the parties shall be lodged with
Borrower and the Agent.

                 10.12 SEVERABILITY. The illegality or unenforceability of any
provision of this Agreement or any instrument or agreement required hereunder
shall not in any way affect or impair the legality or enforceability of the
remaining provisions of this Agreement or any instrument or agreement required
hereunder.

                 10.13 NO THIRD PARTIES BENEFITED. This Agreement is made and
entered into for the sole protection and legal benefit of Borrower, the Agent
and the Lenders, and their permitted successors and assigns, and no other Person
shall be a direct or indirect legal beneficiary of, or have any direct or
indirect cause of action or claim in connection with, this Agreement or any of
the other Loan Documents. No Agent or Lender shall have any obligation to any
Person not a party to this Agreement or the other Loan Documents.

                 10.14 TIME. Time is of the essence of each term and provision
of this Agreement and each of the other Loan Documents.

                 10.15    GOVERNING LAW.  THIS AGREEMENT AND THE NOTES SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
CALIFORNIA; PROVIDED THAT THE AGENT AND THE LENDERS SHALL RETAIN ALL RIGHTS
ARISING UNDER FEDERAL LAW.

                 10.16 WAIVER OF JURY TRIAL. BORROWER, THE AGENT, AND THE
LENDERS EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR
CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE
OTHER LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY
ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE PARTIES
AGAINST ANY OTHER PARTY OR PARTIES, WHETHER WITH RESPECT TO CONTRACT CLAIMS,
TORT CLAIMS, OR OTHERWISE. SUBJECT TO SECTION 10.17 BELOW, BORROWER, THE AGENT,
AND THE LENDERS EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED
BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES
FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY
OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING
WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF
THIS AGREEMENT OR






                                      118
<PAGE>   119


THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF. THIS WAIVER SHALL
APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO
THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

                 10.17    ARBITRATION.

                 (a) Mandatory Arbitration. Any controversy or claim between or
among the parties arising out of or relating to this Agreement, the Loan
Documents, and any claim based on or arising from an alleged tort, shall at the
request of any party be determined by arbitration. The arbitration shall be
conducted in Los Angeles, California, in accordance with the United States
Arbitration Act (Title 9, U.S. Code), notwithstanding any choice of law
provision in this Agreement, and under the Commercial Rules of the American
Arbitration Association (the "AAA"). The arbitrator(s) shall give effect to
statutes of limitation in determining any claim. Any controversy concerning
whether an issue is arbitrable shall be determined by the arbitrator(s).
Judgment upon the arbitration award may be entered in any court having
jurisdiction. The institution and maintenance of an action for judicial relief
or pursuit of a provisional or ancillary remedy shall not constitute a waiver of
the right of any party, including the plaintiff, to submit the controversy or
claim to arbitration if any other party contests such action for judicial
relief.

                 (b) Provisional Remedies, Self-Help and Foreclosure. No
provision of this Section 10.17 shall limit the right of any party to this
Agreement to exercise self-help remedies such as setoff, foreclosure against or
sale of any real or personal property collateral or security, or to obtain
provisional or ancillary remedies from a court of competent jurisdiction before,
after, or during the pendency of any arbitration or other proceeding. The
exercise of a remedy does not waive the right of either party to resort to
arbitration.

                 10.18 NOTICE OF CLAIMS; CLAIMS BAR. BORROWER HEREBY AGREES THAT
IT SHALL GIVE PROMPT WRITTEN NOTICE TO THE AGENT OF ANY CLAIM OR CAUSE OF ACTION
IT BELIEVES IT HAS, OR MAY SEEK TO ASSERT OR ALLEGE AGAINST THE AGENT OR ANY
LENDER, WHETHER SUCH CLAIM IS BASED IN LAW OR EQUITY, ARISING UNDER OR RELATED
TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, OR TO THE LOANS, OR ANY
ACT OR OMISSION TO ACT BY THE AGENT OR ANY LENDER WITH RESPECT HERETO OR
THERETO, AND THAT IF BORROWER SHALL FAIL TO GIVE SUCH PROMPT NOTICE TO THE AGENT
WITH REGARD TO ANY SUCH CLAIM OR CAUSE OF ACTION, BORROWER SHALL BE DEEMED TO
HAVE WAIVED, AND SHALL BE FOREVER BARRED FROM BRINGING OR ASSERTING,






                                      119
<PAGE>   120


SUCH CLAIM OR CAUSE OF ACTION IN ANY ARBITRATION OR ANY SUIT, ACTION OR
PROCEEDING IN ANY COURT OR BEFORE ANY GOVERNMENTAL AGENCY.

                 10.19 ENTIRE AGREEMENT. This Agreement, together with the other
Loan Documents, embodies the entire agreement and understanding between
Borrower, the Agent and the Lenders. Accordingly, this Agreement, together with
the other Loan Documents, supersedes all prior or contemporaneous agreements and
understandings of such Persons, verbal or written, relating to the subject
matter hereof and thereof, except for any prior arrangements made with respect
to the payment by Borrower of (or any indemnification for) any fees, costs,
expenses, liabilities, damages or claims payable to or incurred (or to be
incurred) by or on behalf of the Agent or the Lenders.

                 10.20 INTERPRETATION. This Agreement, together with the other
Loan Documents, is the result of negotiations between and has been reviewed by
counsel to the Agent, the Lenders and Borrower and other parties, and is the
product of all parties hereto. Accordingly, this Agreement and the other Loan
Documents shall not be construed against the Lenders or the Agent merely because
of the Agent's or Lender's involvement in the preparation of such documents and
agreements.

                 10.21 EXCULPATION OF LENDERS. No Lender undertakes or assumes
any responsibility or duty to Borrower or any third party to select, review,
inspect, examine, supervise, pass judgment upon or inform Borrower or any third
party of the existence, quality, adequacy or suitability of: (a) any
environmental report, or (b) any other matters or items, including, but not
limited to, engineering, soils and seismic reports which are contemplated in the
Loan Documents. Any such selection, review, inspection, examination and the like
is solely for the purpose of protecting the Lenders' security and preserving the
Lenders' rights under the Loan Documents, and shall not render any Lender liable
to Borrower or any third party for the existence, sufficiency, accuracy,
completeness or legality thereof. No Lender owes any duty of care to protect or
inform Borrower or any third party against negligent, faulty, inadequate or
defective building or construction or the existence of any environmentally
hazardous condition affecting any Property.

                 10.22 RELATIONSHIP. Nothing herein contained shall in any
manner be construed as creating any relationship between the Agent and the
Lenders, on the one hand, and Borrower, on the other hand, other than as
creditor and debtor. Borrower agrees to indemnify, protect, defend and hold the
Agent and each Lender harmless from and against any and all losses, liabilities,
damages, and costs and expenses (including, but not limited to,






                                      120
<PAGE>   121


reasonable attorneys' fees and disbursements, including reasonably allocated
costs of in-house counsel) resulting from any other construction of the parties'
relationship.

                 10.23 CONFIDENTIALITY. Agent and each Lender shall keep all
information delivered under Section 6.1(d) confidential in accordance with this
Section 10.23 and shall hold all other non-public information obtained pursuant
to the requirements of this Agreement which has been identified as confidential
by Borrower in accordance with Agent's and such Lender's customary procedures
for handling confidential information of this nature and in accordance with safe
and sound banking practices, it being understood and agreed by Borrower that in
any event Agent or a Lender may make disclosures reasonably required by any bona
fide assignee, transferee or participant in connection with the contemplated
assignment or transfer by Agent or such Lender of any Loans or any participation
therein or as required or requested by any governmental agency or 
representative thereof or pursuant to legal process.

                 10.24    CONSENT TO JURISDICTION AND SERVICE OF PROCESS.

ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST BORROWER ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY OBLIGATIONS THEREUNDER, MAY BE
BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE STATE OF
CALIFORNIA, COUNTY OF LOS ANGELES. BY EXECUTING AND DELIVERING THIS AGREEMENT,
BORROWER, IRREVOCABLY

                  (I)    ACCEPTS GENERALLY AND UNCONDITIONALLY THE NONEXCLUSIVE
                         JURISDICTION AND VENUE OF SUCH COURTS;

                  (II)   WAIVES ANY DEFENSE OF FORUM NON CONVENIENS;

                  (III)  AGREES THAT SERVICE OF ALL PROCESS IN ANY SUCH
                         PROCEEDING IN ANY SUCH COURT MAY BE MADE BY REGISTERED
                         OR CERTIFIED MAIL, RETURN RECEIPT REQUESTED, TO COMPANY
                         AT ITS ADDRESS SET FORTH HERE;

                  (IV)   AGREES THAT SERVICE AS PROVIDED IN CLAUSE (III) ABOVE
                         IS SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER
                         BORROWER IN ANY SUCH PROCEEDING IN ANY SUCH COURT, AND
                         OTHERWISE CONSTITUTES EFFECTIVE AND BINDING SERVICE IN
                         EVERY RESPECT;

                  (V)    AGREES THAT AGENT RETAINS THE RIGHT TO SERVE PROCESS IN
                         ANY OTHER MANNER PERMITTED BY LAW OR TO BRING
                         PROCEEDINGS AGAINST BORROWER IN THE COURTS OF ANY OTHER

                                 PROMISSORY NOTE

                                                                 October 1, 1998

                                                         Los Angeles, California


         FOR VALUE RECEIVED, AIMCO Properties, L.P., a Delaware limited
partnership (the "Borrower"), promises to pay to the order of BANK OF AMERICA
NATIONAL TRUST AND SAVINGS ASSOCIATION ("Lender") the principal amount of SIXTY
FIVE MILLION AND NO/100 DOLLARS ($65,000,000) or, if less, the aggregate amount
of Loans (as such term and all other capitalized terms used but not defined
herein are defined in the Credit Agreement referred to below) made by the Lender
to the Borrower pursuant to the Credit Agreement referred to below, outstanding
on the Revolving Facility Maturity Date or, if the Borrower duly converts the
Revolving Facility to the Term Loan pursuant to the Credit Agreement, on the
Term Loan Maturity Date.

                  The Borrower also promises to make principal payments and
interest on the unpaid principal amount hereof from the date hereof until paid
at the rates and at the times which shall be determined in accordance with the
provisions of the Credit Agreement.

                  All payments of principal and interest in respect of this Note
shall be made in lawful money of the United States of America in same day funds
at the Payment Office. Until notified of the transfer of this Note, the Borrower
shall be entitled to deem the Lender or such person who has been so identified
by the transferor in writing to the Borrower as the holder of this Note, as the
owner and holder of this Note. The Lender and any subsequent holder of this Note
agrees that before disposing of this Note, or any part hereof, it will make a
notation hereon of all principal payments previously made hereunder of the date
to which interest hereon has been paid on the schedule attached hereto, if any;
provided, however, that the failure to make notation of any payment made on this
Note shall not limit or otherwise affect the obligation of the Borrower
hereunder with respect to payments of principal or interest on this Note.

                  This Note is referred to in, and is entitled to the benefits
of, the Amended and Restated Credit Agreement (Unsecured Revolver-to-Term
Facility) dated as of the even date herewith, (the "Credit Agreement"), among
the Borrower, the lenders from time to time party thereto, Bank of America
National Trust and Savings Association, as Agent, and BankBoston N.A., as
Documentation Agent. The Credit Agreement, among other things, (i) provides for
the making of loans (the "Loans") by the Lender to the Borrower from time to
time in an aggregate amount first above mentioned, the indebtedness of the
Borrower resulting from each such Loan being evidenced by this Note, and (ii)
contains provisions for acceleration of the maturity hereof upon the happening
of certain stated events and also for mandatory and optional prepayments on
account of principal hereof and certain principal payments prior to the maturity
hereof upon the terms and conditions therein specified.

                  The terms of this Note are subject to amendment only in the
manner provided in the Credit Agreement.

<PAGE>   2






                  No reference herein to the Credit Agreement and no provision
of this Note or the Credit Agreement shall alter or impair the obligation of the
Borrower, which is absolute and unconditional, to pay the principal of and
interest on this Note at the place, at the respective times, and in the currency
herein prescribed.

                  The Borrower promises to pay all costs and expenses, including
reasonable attorneys' fees, incurred in the collection and enforcement of this
Note. The Borrower hereby waives diligence, presentment, and protest, and except
as provided in the Credit Agreement, demand and notice of every kind and, to the
full extent permitted by law, the right to plead any statute of limitations as a
defense to any demand hereunder.

                  This Note shall be governed by, and construed in accordance
with, the laws of the state of California without giving effect to its choice of
law doctrine.

                  IN WITNESS WHEREOF, the Borrower has caused this Note to be
executed and delivered by its duly authorized officer, as of the date and place
first above written.

APARTMENT INVESTMENT AND MANAGEMENT COMPANY AND INSIGNIA FINANCIAL GROUP, INC. 
COMPLETE MERGER

DENVER, and GREENVILLE, S.C., Oct. 2 /PRNewswire/ -- Apartment Investment and
Management Company (NYSE: AIV "AIMCO") and Insignia Financial Group, Inc. (NYSE:
IFS "Insignia") announced the completion of the merger of Insignia, which holds
a multifamily business, including a majority interest in Insignia Properties
Trust ("IPT"), into AIMCO on October 1, 1998. AIMCO is now the largest private
provider of rental housing in the world, operating more than 2,000 properties,
including nearly 400,000 apartment units or one-third of all apartment units
owned by the 23 publicly-traded multifamily REITs, and serving approximately one
million residents.

In the merger, AIMCO will issue approximately $310 million of equity by
exchanging each outstanding share of Insignia common stock for 0.262 shares of
AIMCO Series E Cumulative Convertible Preferred Stock ("Series E Preferred
Stock"), or an aggregate of approximately 8.9 million shares. The Series E
Preferred Stock will be automatically converted into AIMCO common stock
following payment of a special dividend of approximately $50 million payable to
Series E Preferred stockholders prior to January 15, 1999. The special dividend
is equivalent to $1.4626 per share of Insignia common stock. The Series E
Preferred Stock will begin trading on October 2, 1998 on the New York Stock
Exchange under the symbol "AIVPrE". In addition, AIMCO has repaid approximately
$325 million of Insignia indebtedness with the proceeds from loans from
financial institutions and assumed approximately $149 million of 6-1/2%
preferred convertible securities issued by an Insignia subsidiary.

On September 21, 1998, Insignia shareholders also received a distribution of the
common stock of Insignia/ESG Holdings, Inc. [NYSE: IEG], the owner of Insignia's
U.S. and international commercial real estate services business, single family
residential brokerage business, New York cooperative and condominium housing
management business and certain other businesses, which trades on the New York
Stock Exchange under the symbol "IEG".

"We are pleased that AIMCO and Insignia have completed their merger. AIMCO is
gratified that Moody's yesterday confirmed its ratings on AIMCO's outstanding
senior debt and preferred stock, albeit with a revision of its ratings outlook
from stable to negative because of general capital market conditions. Our
shareholders will benefit from the combined strengths of Insignia's multifamily
business and the people who have been working with our AIMCO team on an
integration program that will be operational on day one of the merger. We wish
Andrew Farkas and his team continued success with Insignia/ESG Holdings, Inc.
and we look forward to his continuing support as a significant AIMCO
shareholder. For the many Insignia employees who will join our AIMCO team, we
welcome you and look forward to a long and profitable relationship," commented
Terry Considine, Chairman and CEO of AIMCO.

"Insignia is extremely pleased to see the transaction with AIMCO come to a
successful conclusion. The merger between Insignia and AIMCO -- as well as the
spin-off of Insignia/ESG Holdings -- allows Insignia shareholders to
participate, in a meaningful way, in the creation of the largest apartment
company in the U.S., and the continued development of an international real
estate service provider through Insignia/ESG Holdings," said Andrew L. Farkas,
Chairman and Chief Executive Officer of Insignia/ESG Holdings, Inc. "We wish
the very best to Terry Considine and his most capable management team, as well
as to the many Insignia employees who will be joining AIMCO."

AIMCO is a real estate investment trust with headquarters in Denver, Colorado
and 33 regional operating centers, which holds a geographically diversified
portfolio of apartment communities. Upon completion of the Merger, AIMCO,
through its subsidiaries, becomes the largest private provider of rental housing
in the world operating more than 2,000 properties, including nearly 400,000
apartment units or one-third of all apartment units owned by the 23
publicly-traded multifamily REITs, and serving approximately one million
residents. The properties are located in 49 states, the District of Columbia and
Puerto Rico.

APARTMENT INVESTMENT AND MANAGEMENT COMPANY AND INSIGNIA PROPERTIES TRUST 
EXECUTE MERGER AGREEMENT

DENVER, COLORADO and GREENVILLE, SOUTH CAROLINA
October 5, 1998 (NYSE: AIV and AMEX: FFO)

     Apartment Investment and Management Company ("AIMCO") and Insignia 
Properties Trust ("IPT") announced today that on Friday, October 2, 1998, they 
executed a definitive merger agreement providing for the acquisition by AIMCO 
of the outstanding shares of IPT not owned by AIMCO at a price of approximately 
$13.25 per share ($13.28 per share if AIMCO issues its common stock in the 
merger) or approximately $151 million in the aggregate. At AIMCO's option, the 
$151 million will be paid in either AIMCO common stock or cash (or any 
combination thereof).

     As previously announced, AIMCO completed its merger with Insignia 
Financial Group, Inc. ("Insignia") on October 1, 1998. In that merger, AIMCO 
succeeded to Insignia's controlling interest in IPT. The AIMCO/IPT merger was 
unanimously approved by the trustees of IPT prior to the closing of the 
AIMCO/Insignia merger. Lehman Brothers rendered its opinion to the Board of 
Trustees of IPT that the merger consideration is fair from a financial point of 
view to the holders of IPT shares, other than AIMCO.

     "When completed, the IPT acquisition will continue AIMCO's growth strategy 
of increasing its investment in real estate through the acquisitions of general 
and limited partnership interests in real estate limited partnerships, the 
primary assets owned by IPT," commented Peter Kompaniez, AIMCO's President.

     AIMCO is a real estate investment trust with headquarters in Denver, 
Colorado and 33 regional operating centers, which holds a geographically 
diversified portfolio of apartment communities. AIMCO, through its 
subsidiaries, is the largest private provider of rental housing in the world 
operating more than 2,000 properties, including nearly 400,000 apartment units 
or one-third of all apartment units owned by the 23 publicly-traded multifamily 
REITs, and serving approximately one million residents. The properties are 
located in 49 states, the District of Columbia and Puerto Rico.
