                    6,000,000 SERIES A PREFERRED SECURITIES

                         ------------------------------
 
   
    The     % Series A REIT Trust Originated Preferred Securities (the "Series A
Preferred Securities") offered hereby (the "Offering") are being sold by IAC
Capital Trust, a Delaware business trust (the "Trust"). The Trust is a limited
purpose financing vehicle established by Irvine Apartment Communities, L.P., a
Delaware limited partnership (the "Operating Partnership"), and Irvine Apartment
Communities, Inc. (the "Company"), a Maryland corporation and the sole general
partner of the Operating Partnership. The proceeds from the Offering will be
used by the Trust to purchase     % Series A Preferred Limited Partner Interests
("Series A Preferred L.P. Units") in the Operating Partnership which will use
the proceeds to repay outstanding indebtedness and for general partnership
purposes. From time to time the Trust may issue additional series of preferred
securities (together with the Series A Preferred Securities, the "Preferred
Securities") and invest the proceeds therefrom in additional series of preferred
limited partner interests of the Operating Partnership (together with the Series
A Preferred L.P. Units, the "Preferred L.P. Units"). The Company and certain
members of management of the Company will own all of the common securities (the
"Common Securities") of the Trust. The Common Securities and the Preferred
Securities (collectively, the "Trust Securities") will represent undivided
beneficial interests in the assets of the Trust, subject to the priority and
payment terms of the Trust Securities. The Trust exists for the sole purpose of
issuing its Preferred Securities and Common Securities and investing the
proceeds thereof primarily in an equivalent amount of Preferred L.P. Units of
the Operating Partnership.
    
                                                        (continued on next page)
 
   
    Application has been made to list the Series A Preferred Securities on the
New York Stock Exchange, Inc. (the "NYSE"). Trading of the Series A Preferred
Securities on the NYSE is expected to commence within a 30-day period after the
date of this Prospectus. While the Underwriters have advised the Trust that they
intend to make a market in the Series A Preferred Securities prior to
commencement of trading on the NYSE, they are under no obligation to do so and
no assurance can be given that a market for the Series A Preferred Securities
will exist prior to commencement of trading. See "Underwriting." See "Glossary"
beginning on page 107 for definitions of certain terms used in this Prospectus.
    
 
   
      SEE "RISK FACTORS" BEGINNING ON PAGE 17 FOR A DISCUSSION OF MATERIAL RISKS
RELEVANT TO AN INVESTMENT IN THE SERIES A PREFERRED SECURITIES, INCLUDING:
    
 
   
- - The Trust's ability to make distributions and other payments on the Series A
  Preferred Securities is initially effectively dependent upon the Operating
  Partnership making distributions and other payments on the Series A Preferred
  L.P. Units held as trust assets. As a result, if the Operating Partnership
  does not make distributions or other payments on the Series A Preferred L.P.
  Units for any reason, it is expected that the Trust will not be able to make
  payments on the Series A Preferred Securities;
    
 
   
- - The Series A Preferred Securities have no voting rights except in limited
  circumstances;
    
 
   
- - Substantial influence of The Irvine Company over the affairs of the Operating
  Partnership and conflicts of interest between The Irvine Company and the
  Operating Partnership;
    
 
   
- - Risks associated with development or acquisition of apartment community
  properties both on and off the Irvine Ranch, including land use entitlement,
  construction, lease-up and financing risks; and
    
 
   
- - Real estate operations and development risks may adversely affect the
  Operating Partnership's ability to make distributions on the Series A
  Preferred L.P. Units.
    
 
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.

    several Underwriters against certain liabilities, including liabilities

    overallotments. The Operating Partnership will pay Underwriters'
    Compensation in the amount per Series A Preferred Security set forth in Note
    3 with respect to such additional Series A Preferred Securities. If all such
    Series A Preferred Securities are purchased, the total Price to Public,
    Underwriting Commission and Proceeds to Trust will be $172,500,000,
    $        and $172,500,000, respectively. See "Underwriting."

     Holders of the Series A Preferred Securities will be entitled to receive
upon declaration by the Trust cumulative preferential cash distributions at an
annual rate of      % of the liquidation amount of $25 per Series A Preferred
Security, accruing from the date of original issuance of the Series A Preferred
Securities and payable quarterly in arrears on           ,           ,
          and           of each year, commencing on           , 1998. The Trust,
as the holder of the Series A Preferred L.P. Units, will be entitled to receive
upon declaration by the Operating Partnership cumulative preferential cash
distributions at the annual rate of      % of the stated value of $25 per Series
A Preferred L.P. Unit, accumulating from the date of original issuance of the
Series A Preferred L.P. Units and payable quarterly in arrears on           ,
          ,           and           of each year, commencing           , 1998.
Cash distributions on the Series A Preferred Securities and the Series A
Preferred L.P. Units in arrears will accumulate without interest. If
distributions are not paid on Preferred L.P. Units deposited in the Trust as
trust assets, including the Series A Preferred L.P. Units, the Trust will not
make payments on the Series A Preferred Securities.
    
 
   
     So long as any Series A Preferred L.P. Units are outstanding except as
otherwise described herein, no distribution shall be paid or declared on the
regular limited partner interests in the Operating Partnership (the "Common L.P.
Units"), the general partnership interest in the Operating Partnership (the
"G.P. Units") or any other series of outstanding Preferred L.P. Units of the
Operating Partnership ranking junior as to the payment of distributions to the
Series A Preferred L.P. Units (collectively, the "Junior OP Units") nor shall
any sum or sums be set aside for or applied to the purchase or redemption of the
Series A Preferred L.P. Units or any other series of outstanding Preferred L.P.
Units or the purchase, redemption or other acquisition for value of any Junior
OP Units unless, in each case, full cumulative distributions accumulated on all
Series A Preferred L.P. Units and all other outstanding series of Preferred L.P.
Units ranking on a parity with the Series A Preferred L.P. Units as to the
payment of distributions have been paid in full. Distributions with respect to
the Series A Preferred Securities will be senior to distributions on the Common
Securities and will have the same priority with respect to distributions on
other series of Preferred Securities as are set forth in this paragraph. See
"Description of Series A Preferred Securities -- Distributions."
    
 
   
     Except as described below, the Series A Preferred L.P. Units are not
redeemable prior to           . On or after           , the Series A Preferred
L.P. Units may be redeemed at the option of the Operating Partnership, in whole
or from time to time in part, at a redemption price of $25 per Series A
Preferred L.P. Unit, plus accumulated and unpaid distributions, if any, to the
redemption date. The Series A Preferred L.P. Units may also be redeemed, in
whole but not in part, at any time upon the occurrence of a Tax Event or
Investment Company Act Event (each as defined herein). The redemption price of
the Series A Preferred L.P. Units (other than the portion consisting of
accumulated and unpaid distributions) will be payable solely out of the sale
proceeds of capital stock of the Company, which will be contributed by the
Company to the Operating Partnership as an additional capital contribution, or
the sale proceeds of Common L.P. Units or Preferred L.P. Units (collectively,
"L.P. Units") of the Operating Partnership, and from no other source. The Series
A Preferred L.P. Units will have a stated maturity of December 31, 2092, which
corresponds to the term of the Operating Partnership. See "Description of the
Series A Preferred L.P. Units -- Redemption." If the Operating Partnership
redeems Series A Preferred L.P. Units, the Trust will redeem in cash Series A
Preferred Securities having an aggregate liquidation amount equal to the
aggregate stated value of the Series A Preferred L.P. Units so redeemed, at $25
per Series A Preferred Security plus accumulated and unpaid distributions
thereon (the "Redemption Price") to the date of redemption. See "Description of
the Series A Preferred Securities -- Redemption." The Series A Preferred L.P.
Units and the Series A Preferred Securities will not be subject to any sinking
fund and, except as described in this Prospectus under "Description of the
Series A Preferred Securities -- Restrictions on Ownership and Transfer of
Series A Preferred Securities," neither the Series A Preferred L.P. Units nor
the Series A Preferred Securities will be convertible into any securities of the
Company, the Operating Partnership or the Trust.

                               PROSPECTUS SUMMARY
 
   
     The following summary is qualified in its entirety by the more detailed
financial and other information appearing elsewhere in this Prospectus. Unless
otherwise indicated, all information in this Prospectus relates to the
properties of the Operating Partnership as of September 30, 1997. In addition,
all property, statistical and operating data relating to the Existing
Communities (as defined herein) in this Prospectus presented as of any date
prior to, or for any period ending on or prior to, June 30, 1997 excludes data
for The Villas of Renaissance (as defined herein), which the Operating
Partnership acquired on June 30, 1997. All data relating to the Existing
Communities presented as of June 30, 1997 or any later date, or for any period
ending after June 30, 1997, includes data for The Villas of Renaissance, unless
otherwise indicated. See "Recent Developments -- 'Off-Ranch' Expansion." Unless
otherwise indicated, all references in this Prospectus to The Irvine Company's
interest in the Operating Partnership or its ownership of Common L.P. Units
includes the interest and ownership of its affiliates. The Operating Partnership
refers to its multifamily rental apartment properties as communities.
    
 
                           THE OPERATING PARTNERSHIP
 
   
     Irvine Apartment Communities, L.P., a Delaware limited partnership, is
engaged in the development and operation of multifamily rental apartment
communities in California. The Operating Partnership's management and operating
decisions are under the unilateral control of Irvine Apartment Communities,
Inc., a Maryland corporation, a self-administered equity real estate investment
trust. The Operating Partnership and the Company were formed in December 1993 to
continue and expand the apartment community business of The Irvine Company, a
real estate and community development company. At September 30, 1997, the
Company had a 45.2% (44.4% as of December 16, 1997) general partnership interest
in the Operating Partnership and was its sole managing general partner. At such
date, the limited partners of the Operating Partnership had a 54.8% (55.6% as of
December 16, 1997) interest in the Operating Partnership, represented by the
Common L.P. Units, with The Irvine Company and certain of its affiliates owning
a 54.6% (55.4% as of December 16, 1997) limited partnership interest in the
Operating Partnership.
    
 
     As of September 30, 1997, the Operating Partnership owned and operated
14,991 units in 51 high-quality apartment communities (the "Existing
Communities") and had four additional apartment communities aggregating 1,110
units under construction (the "Communities Under Construction" and, together
with the Existing Communities, the "Properties"). Upon completion of the
Communities Under Construction, the Operating Partnership will own a total of
16,101 units in 55 apartment communities, representing an increase in units of
approximately 42% since the Company's initial public offering (the "Initial
Public Offering") in December 1993. Through July 2020, the Company and the
Operating Partnership hold the exclusive right, but not the obligation, to
acquire land from The Irvine Company, the owner and developer of the Irvine
Ranch since 1864, for development of additional apartment communities on the
Irvine Ranch. Fifty-three of the Properties aggregating 14,836 units (the
"Irvine Ranch Properties") are or will be located on the Irvine Ranch, of which
50 constitute Existing Communities (14,068 units) and three constitute
Communities Under Construction (768 units).
 
   
     In 1997, the Operating Partnership commenced an "off-Ranch" expansion
program through the acquisition of rights to purchase three apartment community
development sites located in Northern California's Silicon Valley. The Operating
Partnership has exercised its right with respect to one of these sites and has
begun construction on a 342-unit apartment community on the site. On October 23,
1997, the Board of Directors of the Company authorized the Operating
Partnership, subject to receipt of necessary entitlements, to exercise another
of the options. Construction of an apartment community of approximately 155
units on this site is expected to commence in the first half of 1998.
Preliminary design and jurisdictional approvals are also in process with respect
to the remaining development site. In addition, on June 30, 1997, the Operating
Partnership purchased for $127 million an existing 923-unit apartment community
("The Villas of Renaissance") located in Northern San Diego County (the "Villas
of Renaissance Acquisition"). Two additional sites located in Northern San Diego
County were purchased in early December, 1997. See "Recent
Developments -- 'Off-Ranch' Expansion." The Operating Partnership believes that
the economic expansion
    
 
                                        5
<PAGE>   7
 
being experienced by the State of California provides the Operating Partnership
with significant growth potential beyond the Irvine Ranch.
 
     The Irvine Ranch is located in central Orange County, California between
San Diego and Los Angeles. The western boundary of the Irvine Ranch borders
approximately six miles of the Pacific Ocean. Today, the portion of the Irvine
Ranch which is still owned by The Irvine Company covers approximately 50,000
acres and includes the largest remaining privately-owned undeveloped acreage in
Orange County. The developed portion of the Irvine Ranch, which includes the
City of Irvine and significant parts of the cities of Newport Beach and Tustin,
is one of the largest urban master-planned communities in the United States. The
Irvine Ranch has been developed over the past 30 years in accordance with an
original master plan (the "Master Plan") which, over time, has been refined to
accord with locally approved general plans. The Irvine Ranch is one of the major
commercial, industrial, retail and residential centers in Southern California.
 
     The Operating Partnership believes that a variety of factors have
contributed to the strong apartment market in Orange County, the successful
operating performance of the Existing Communities located on the Irvine Ranch
and the existence of significant opportunities for the development of additional
apartment communities on the Irvine Ranch. Most important among these factors
are:
 
     - The dominant market position of the Operating Partnership, which owns
       over 85% of all apartment communities having 100 or more units on the
       Irvine Ranch;
 
     - The Operating Partnership's 23-year exclusive right to acquire land from
       The Irvine Company for development of additional rental apartment
       communities on the Irvine Ranch;
 
     - The limited supply of developable land, other than on the Irvine Ranch,
       adjacent to major employment centers in Orange County;
 
     - The Irvine Company's Master Plan strategy which emphasizes market
       segmentation in order to ensure adequate and appropriate allocation of
       land uses which support sustained growth for the long-term;
 
     - The high quality of design, construction and maintenance of the Irvine
       Ranch Properties and their location in or near the City of Irvine, which
       was ranked by the Federal Bureau of Investigation as among the safest
       cities in the United States with a population of 100,000 or more;
 
     - The close proximity of the Irvine Ranch Properties and of future
       development sites to major employment centers, the Pacific Ocean, high
       quality schools, and extensive resort, recreational and open space
       amenities;
 
     - An affluent, growing population and diversified employment base in Orange
       County and on the Irvine Ranch;
 
     - The Operating Partnership's ability to defer the purchase of land on the
       Irvine Ranch under its land rights agreement until site and zoning
       entitlements have been obtained, the land is ready for construction and
       the Operating Partnership determines favorable market conditions exist;
 
     - The operating efficiencies available to the Operating Partnership because
       the Irvine Ranch Properties are located in a single geographic area;
 
     - An average of 20 years of experience of the Company's 11 most senior
       members of management in the design, development, construction, property
       management and financing of apartment communities; and
 
     - The effectiveness of management's policies regarding property management
       and expense control.
 
     The Operating Partnership's intent is to develop or acquire new apartment
communities in California. The Operating Partnership has recently commenced
operations in the Silicon Valley and Northern San Diego County, which possess
strong rental demographics and economic growth prospects similar to those on the
Irvine Ranch.

                               IAC CAPITAL TRUST
 
   
     IAC Capital Trust is a statutory business trust formed on October 31, 1997
under the Delaware Business Trust Act (the "Business Trust Act") pursuant to a
declaration of trust, among the Trustees (as defined herein), the Company and
the Operating Partnership, and the filing of a certificate of trust with the
Secretary of State of the State of Delaware. Such declaration will be amended
and restated in its entirety (as so amended and restated, the "Declaration")
substantially in the form filed as an exhibit to the Registration Statement of
which this Prospectus forms a part, as of the date the Series A Preferred
Securities are initially issued. The Company and certain members of management
of the Company will acquire all of the Common Securities of the Trust for an
aggregate consideration of $5,000. From time to time the Trust may issue
additional series of Preferred Securities and invest the proceeds of any such
issuance in an additional series of Preferred L.P. Units of the Operating
Partnership. The Trust Securities represent undivided beneficial interests in
the assets of the Trust, subject to the priority and payment terms of the Trust
Securities, and are not secured by any assets of the Operating Partnership or
any of its affiliates. The Trust is a limited purpose financing vehicle
established by the Company and the Operating Partnership and exists solely for
the purpose of (a) issuing its Preferred Securities (and, if applicable, Excess
Preferred Securities (as defined herein)), (b) issuing its Common Securities to
the persons described above and investing the proceeds thereof in an interest
bearing account in, or certificate of deposit of, a bank, (c) investing the
proceeds from the sale of each series of Preferred Securities in a series of
Preferred L.P. Units of the Operating Partnership and (d) engaging in such other
activities as are necessary, convenient or incidental thereto. The rights of the
holders of the Trust Securities, including economic rights, rights to
information and voting rights, are as set forth in the Declaration and the
Business Trust Act. The Preferred Securities have no voting rights except in
limited circumstances. The Declaration does not permit the incurrence by the
Trust of any indebtedness for borrowed money or the making of any investment
other than in Preferred L.P. Units of the Operating Partnership and as described
above in connection with the investment of the proceeds from the sale of the
Common Securities. In the Declaration, the Operating Partnership has agreed to
reimburse all obligations (other than with respect to the Trust Securities) and
all costs and expenses of the Trust, including the fees and expenses of the
Trustees and any income taxes, duties and other governmental charges, and all
costs and expenses with respect thereto, to which the Trust may become subject,
except for withholding taxes. For a more detailed description of the rights of
holders of the Series A Preferred Securities, see "-- The Offering," "IAC
Capital Trust" and "Description of the Series A Preferred Securities."

                                  RISK FACTORS
 
     PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER THE MATTERS DISCUSSED UNDER
"RISK FACTORS" PRIOR TO MAKING AN INVESTMENT DECISION REGARDING THE SERIES A
PREFERRED SECURITIES OFFERED HEREBY. SOME OF THE SIGNIFICANT CONSIDERATIONS
INCLUDE:
 
   
     - The Trust's ability to make distributions and other payments on the
       Series A Preferred Securities is initially effectively dependent upon the
       Operating Partnership making distributions and other payments on the
       Series A Preferred L.P. Units held as trust assets. As a result, if the
       Operating Partnership does not make distributions or other payments on
       the Preferred L.P. Units deposited in the Trust as trust assets,
       including the Series A Preferred L.P. Units, for any reason, it is
       expected that the Trust will not be able to make payments on the Series A
       Preferred Securities.
    
 
   
     - The Series A Preferred Securities have no voting rights except in limited
       circumstances.
    
 
   
     - The taxation of the Trust as a corporation if it fails to qualify as a
       REIT could result in increased costs to the Operating Partnership since
       it will be responsible for such taxes and may result in the redemption of
       the Series A Preferred Securities. See "Description of the Series A
       Preferred Securities -- Redemption" and "Description of the Series A L.P.
       Units -- Redemption."
    
 
   
     - The restriction on ownership of more than 9.8% of the outstanding Series
       A Preferred Securities (the "Ownership Limit"). If the Ownership Limit is
       exceeded, Series A Preferred Securities in excess of the Ownership Limit
       will automatically be exchanged for Excess Preferred Securities which
       have limited rights.
    
 
   
     - Conflicts of interest with, and influence of, The Irvine Company,
       including the substantial influence of The Irvine Company and its three
       nominees to the Board of Directors of the Company over the affairs of the
       Operating Partnership.
    
 
   
     - The Irvine Company will determine which land will be designated for
       rental apartment community development on the Irvine Ranch. Since The
       Irvine Company also develops industrial, commercial and other properties
       on the Irvine Ranch, the feasibility and development of additional
       apartment communities by the Operating Partnership on the Irvine Ranch
       may be adversely affected by the feasibility and development of
       commercial, industrial and residential for-sale properties by The Irvine
       Company on the Irvine Ranch. In addition, The Irvine Company will control
       the application for initial land use approvals from local governing
       entities ("Village Related Entitlements") and will also have certain
       approval rights with respect to the architectural design and physical
       layout of rental apartment communities.
    
 
   
     - The potential for early termination of the Land Rights Agreement, as
       amended, among the Company, the Operating Partnership, The Irvine Company
       and Mr. Bren (the "Land Rights Agreement") upon the occurrence of certain
       events, including the failure of the shareholders of the Company to elect
       as directors of the Company those persons nominated by The Irvine
       Company. If the Land Rights Agreement is terminated as a result of the
       occurrence of one of these events, the Operating Partnership would no
       longer have an option to acquire apartment community land sites from The
       Irvine Company and The Irvine Company and Mr. Bren would no longer be
       prohibited from acquiring or developing apartment communities on or off
       the Irvine Ranch in competition with the Operating Partnership.
       Accordingly, the termination of the Land Rights Agreement would likely
       have a material adverse effect on the future development activities of
       the Operating Partnership on the Irvine Ranch.
    
 
   
     - Financing risks, including the ability of the Operating Partnership to
       incur substantial indebtedness, subject to certain covenants in the
       Operating Partnership's debt agreements, thereby permitting the Operating
       Partnership to become more highly leveraged. Increased leverage and the
       resulting increase in debt service requirements could adversely affect
       the Operating Partnership's ability to make required distributions on the
       Preferred L.P. Units, including the Series A Preferred L.P. Units, which
       in turn would adversely affect the Trust's ability to make required
       distributions on the Series A Preferred Securities.
    
 
   
     - General real estate investment risks, including:
    
 
                                        9
<PAGE>   11
 
   
      -- risks associated with the development or acquisition of new apartment
         communities, including the possible inability of The Irvine Company to
         obtain Village Related Entitlements (as defined below); construction,
         lease-up and financing risks; and the possibility that newly developed
         or acquired properties will fail to perform as expected;
    
 
   
      -- the effect of local economic conditions, such as unemployment rates,
         supply of and demand for apartments, and other conditions on apartment
         community cash flows and values (including the risk arising from
         concentration of the Properties in Orange County); the ability of
         residents to make rent payments; the ability of a property to generate
         income sufficient to meet operating expenses (including real estate
         taxes) and debt service; and the illiquidity of real estate
         investments, all of which may affect the Operating Partnership's
         ability to make expected distributions; and
    
 
   
      -- potential losses in the event of a casualty loss (e.g., an earthquake)
         that is not insured, insurable or economically insurable.
    
 
   
     - The lack of a prior market for the Series A Preferred Securities.
    
 
   
                                 THE PROPERTIES
    
 
   
     As of September 30, 1997, the Operating Partnership owned and operated
14,991 apartment units in the Existing Communities and had four Communities
Under Construction. The Operating Partnership believes that the Properties are
high quality apartment communities with superior locations near major employment
centers and, in the case of Irvine Ranch Properties, within master-planned
villages. The Properties are located within the following individual
jurisdictions:

              MANAGEMENT AND CONTROL OF THE OPERATING PARTNERSHIP
    
 
   
     As sole general partner of the Operating Partnership, the Company has the
exclusive power to manage and conduct the business of the Operating Partnership.
The Company, in turn, is governed by a Board of Directors, which has a majority
of directors unaffiliated with The Irvine Company. Furthermore, the Board of
Directors of the Company has established a committee of such unaffiliated
directors (the "Independent Directors Committee") whose approval is required
with respect to all transactions involving the Operating Partnership or the
Company on the one hand and The Irvine Company, affiliates of The Irvine Company
or Mr. Bren on the other hand, such as the acquisition of additional apartment
communities or sites therefor from The Irvine Company.
    
 
   
     Consent of The Irvine Company is required by the Second Amended and
Restated Agreement of Limited Partnership of the Operating Partnership (the
"Partnership Agreement") for, among other things, (i) the Operating Partnership
to sell all or substantially all of its assets, (ii) the Company to take title
to assets (other than temporarily in connection with an acquisition prior to
contributing such assets to the Operating
    
 
                                       10

Partnership) or for the Company to conduct business other than through the
Operating Partnership, (iii) the Operating Partnership to engage in any business
other than the development and ownership of apartment communities or (iv) the
Operating Partnership to liquidate, dissolve, wind-up or terminate. The
Partnership Agreement requires, absent receipt of consent, that title to assets
be in the Operating Partnership in order to maintain a one-for-one exchange
ratio between Common L.P. Units and shares of common stock of the Company (the
"Common Stock"). See "Operating Partnership Agreement -- Management."
    
 
   
     At the option of The Irvine Company, The Irvine Company's 54.6% (55.4% as
of December 16, 1997) limited partnership interest in the Operating Partnership
(i) is exchangeable for Common Stock of the Company pursuant to the exchange
rights (the "Exchange Rights") set forth in the Partnership Agreement (subject
to the ownership limit applicable to The Irvine Company and certain related
persons contained in the Articles of Amendment and Restatement (the "Articles of
Incorporation") of the Company), and (ii) may be tendered to the Company for
cash payable solely out of the net proceeds of an offering of Common Stock of
the Company pursuant to the cash tender rights (the "Cash Tender Rights") set
forth in the Partnership Agreement.
    
 
   
                            TAX STATUS OF THE TRUST
    
 
   
     The Trust will elect to be taxed as a REIT under the Code, commencing with
its taxable year ending December 31, 1998, and the Trust intends to operate so
as to qualify as a REIT. In the opinion of Davis Polk & Wardwell, commencing
with the Trust's taxable year ending December 31, 1998, the Trust will be
treated as being organized in conformity with the requirements for qualification
as a REIT, and its proposed method of operation will enable it to meet the
requirements for qualification and taxation as a REIT under current law. This
opinion is based upon certain assumptions and representations made by the Trust
and the Operating Partnership as to factual matters as set forth in this
Prospectus. An opinion of counsel is not binding on the Internal Revenue Service
or the courts. If the Trust qualifies for taxation as a REIT, then under current
federal income tax laws it generally will not be subject to federal corporate
income tax on its net income that is currently distributed to holders of its
Trust Securities to the extent it currently distributes at least 95% of its net
taxable income to the holders of its Trust Securities. Even if the Trust
qualifies for taxation as a REIT, the Trust may be subject to certain federal,
state and local taxes on its income and property and to federal income and
excise tax on its undistributed income. See "Certain Federal Income Tax
Consequences."

                             initially consist solely of the Series A Preferred

                             with proceeds from the sale of the Common

A PREFERRED L.P. UNITS.....  Distributions on the Series A Preferred L.P. Units
                             and the Series A Preferred Securities will accrue
                             from             , 1998 and will be payable at an
                             annual rate of   % of the liquidation amount of $25
                             per security. Distributions will be payable
                             quarterly in arrears on           ,           ,

                                       , 1998. The ability of the Trust to pay
                             distributions on the Series A Preferred Securities
                             is initially effectively dependent on the receipt
                             of distributions from the Operating Partnership on
                             the Series A Preferred L.P. Units. See "Description
                             of the Series A Preferred

                             of the Operating Partnership, at which time the
                             Trust will also terminate, holders of Series A
                             Preferred Securities will be entitled to receive,

                             a series of Preferred Securities having economic
                             terms substantially similar to the Series A

audited financial statements not included herein of the Company and the
Predecessor and is on a combined and consolidated historical basis for the
Operating Partnership and the Predecessor. Information at December 31, 1994 and
1993 has been derived from the Company's audited financial statements not
included herein and information at and for the year ended December 31, 1992 has
been derived from the Predecessor's audited financial statements not included

- ---------------
 
(1) Includes the operations of the Predecessor through December 7, 1993 and of
    the Operating Partnership from December 8 through December 31, 1993.
 
(2) A property is stabilized at the earlier of (i) one year after completion of
    construction or (ii) when it achieves 95% occupancy.
 
(3) With respect to each period presented for communities that have been
    stabilized for less than one year, reflects data from the date of stabilized
    occupancy.
 
(4) Average monthly rent per unit is calculated by dividing the average rental
    revenue per unit by average economic occupancy.
 
   
(5) Data for the year ended December 31, 1992 excludes capital replacements
    totaling $534 per unit relating to a major renovation program at the
    Operating Partnership's Promontory Point apartment community due to the
    nonrecurring nature of the program.
    
 
   
(6) Excludes The Villas of Renaissance, which was acquired on June 30, 1997. If
    The Villas of Renaissance were included for the nine months ended September
    30, 1997, average units in stabilized communities would have been 13,991,
    average physical occupancy in stabilized communities would have been 94.4%,
    average monthly rent per unit would have been $1,104 and capital
    replacements per unit would have been $229.
    
 
   
(7) EBITDA, as adjusted, represents earnings before interest, depreciation and
    amortization and extraordinary items. EBITDA is not necessarily comparable
    to similarly titled measures of other companies, and should not be
    considered as an alternative to operating income, as determined in
    accordance with generally accepted accounting principles ("GAAP"), as an
    indicator of the Operating Partnership's operating performance, or to cash
    flows from operating activities (as determined in accordance with GAAP) as a
    measure of liquidity.
    
 
(8) The Operating Partnership did not have any Preferred L.P. Units outstanding
    in any of the periods indicated, and, therefore, the ratio of EBITDA to
    interest expense and preferred securities distributions for each of the
    periods indicated was equal to the ratio of EBITDA to interest expense for
    such period.

                                  RISK FACTORS
 
   
     Prospective investors should carefully consider the following material
risks in conjunction with the other information contained in this Prospectus
before making an investment in the Series A Preferred Securities.
    
 
   
DEPENDENCE ON OPERATING PARTNERSHIP
    
 
   
     The Trust's ability to make distributions and other payments on the Series
A Preferred Securities is initially effectively dependent upon the Operating
Partnership making distributions and other payments on the Series A Preferred
L.P. Units held as trust assets. If the Operating Partnership does not make
distributions or other payments on the Preferred L.P. Units deposited in the
Trust as trust assets, including the Series A Preferred L.P. Units, for any
reason, it is expected that the Trust will not be able to make payments on the
Series A Preferred Securities.
    
 
   
     The Declaration provides that the Operating Partnership shall reimburse all
costs, expenses and liabilities of the Trust, including any taxes and all costs
and expenses with respect thereto, to which the Trust may become subject, except
with respect to distributions on the Trust Securities and withholding taxes on
such distributions. No assurance can be given that the Operating Partnership
will have sufficient resources to enable it to pay such costs, expenses and
liabilities on behalf of the Trust.
    
 
   
RANKING OF SERIES A PREFERRED L.P. UNITS AND SERIES A PREFERRED SECURITIES
    
 
   
     The Series A Preferred L.P. Units rank junior to all existing and future
debt and other liabilities of the Operating Partnership and its subsidiaries and
senior with respect to distributions and rights upon liquidation, dissolution,
winding-up or termination of the Operating Partnership to the G.P. Units, the
Common L.P. Units now or hereafter issued by the Operating Partnership and on a
parity with any other series of Preferred L.P. Units hereafter issued, unless
the terms of such other series state that such Preferred L.P. Units rank junior
to the Series A Preferred L.P. Units. There are no terms in the Series A
Preferred Securities or the Series A Preferred L.P. Units that restrict the
ability of the Operating Partnership from incurring additional debt or other
liabilities or issuing additional series of Preferred L.P. Units. See
"Description of the Series A Preferred Securities."
    
 
   
NO VOTING RIGHTS EXCEPT IN LIMITED CIRCUMSTANCES
    
 
   
     Holders of Series A Preferred Securities will have limited voting rights
and, subject to the rights of holders of Preferred Securities to appoint a
Special Regular Trustee (as defined herein) upon the occurrence of an
Appointment Event (as defined herein), will not be able to appoint, remove or
replace, or to increase or decrease the number of, Trustees, which rights are
vested exclusively in the Common Securities. See "Description of the Series A
Preferred Securities -- Voting Rights" and "Description of the Series A
Preferred L.P. Units -- Voting Rights."
    
 
ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT
 
     The Trust intends to operate so as to qualify as a REIT under the Code.
 
     Although the Trust believes that it will be organized and will operate in
such a manner, no assurance can be given that the Trust will be able to operate
in such a manner so as to qualify as a REIT under the Code or to remain so
qualified. Qualification as a REIT involves the application of highly technical
and complex Code provisions for which there are only limited judicial or
administrative interpretations. The determination of various factual matters and
circumstances not entirely within the Trust's control may affect its ability to
qualify as a REIT. In addition, no assurance can be given that legislation, new
regulations, administrative interpretations, or court decisions will not
significantly change the tax laws with respect to the qualification as a REIT or
the federal income tax consequences of such qualification; however, the Trust is
not aware of any proposal in Congress to amend the tax laws that would
materially and adversely affect the Trust's ability to operate as a REIT.
 
                                       17
<PAGE>   19
 
   
     The Trust is relying on the opinion of Davis Polk & Wardwell, tax counsel
to the Operating Partnership and the Trust, regarding various issues affecting
the Trust's ability to qualify, and retain qualification, as a REIT. See "Legal
Matters." Such legal opinions are not binding on the Internal Revenue Service
("IRS") or the courts. See "Certain Federal Income Tax Consequences."
    
 
   
     If in any taxable year the Trust fails to qualify as a REIT, the Trust
would not be allowed a deduction for distributions to holders of Trust
Securities in computing its taxable income and would be subject to federal
income tax (including any applicable alternative minimum tax) on its taxable
income at regular corporate rates. This could result in increased costs to the
Operating Partnership since it will be responsible for such taxes. The taxation
of the Trust as a corporation if it fails to qualify as a REIT would generally
permit the Operating Partnership to redeem the Series A Preferred L.P. Units, in
which event the Series A Preferred Securities will also be redeemed. See
"Description of the Series A Preferred L.P. Units -- Redemption."
    
 
   
     Notwithstanding that the Trust currently intends to operate in a manner
designed to qualify as a REIT, future economic, market, legal, tax, or other
considerations may cause the Regular Trustees (as defined herein) and the
holders of the Common Securities to determine that it is in the best interest of
the Trust to revoke the REIT election. The Trust would be disqualified from
electing treatment as a REIT for the four taxable years following the year of
such revocation. The Trust's ability to maintain REIT status will also be
dependent on the nature of the income derived by the Operating Partnership. See
"Certain Federal Income Tax Consequences."
    
 
DISTRIBUTIONS TO HOLDERS OF SERIES A PREFERRED SECURITIES
 
   
     REIT REQUIREMENTS. To obtain the favorable tax treatment for REITs
qualifying under the Code, the Trust generally will be required each year to
distribute to holders of the Trust Securities at least 95% of its otherwise
taxable income (after certain adjustments). In addition, the Trust will be
subject to a 4% excise tax on the amount, if any, by which certain distributions
paid by it with respect to any calendar year are less than the sum of 85% of its
ordinary income for the calendar year, 95% of its capital gains net income for
the calendar year (unless the REIT elects to retain and pay income tax on such
gains) and any undistributed taxable income from prior periods. Failure to
comply with these requirements would result in the Trust's income being subject
to tax at regular corporate rates.
    
 
   
     INABILITY OF TRUST TO MAINTAIN ITS DISTRIBUTION POLICY; DEPENDENCE ON
OPERATING PARTNERSHIP. The Trust's income will consist solely of the Trust's
share of the income of the Operating Partnership, and the Trust's cash flow will
consist solely of its share of distributions from the Operating Partnership.
Differences in timing between the receipt of income and the payment of expenses
in arriving at taxable income (of the Operating Partnership) and the effect of
required debt amortization payments could require the Operating Partnership to
borrow funds on a short-term basis to meet its intended distribution policy.
    
 
   
     The Trust's ability to make distributions on the Series A Preferred
Securities is initially effectively dependent upon the Operating Partnership's
ability to make distributions on the Series A Preferred L.P. Units.
Distributions by the Operating Partnership will be determined by the Board of
Directors of the Company, as general partner of the Operating Partnership.
Accordingly, there is no assurance that the Operating Partnership will declare
distributions on any Preferred L.P. Units deposited in the Trust as trust
assets, including the Series A Preferred L.P. Units, in an amount sufficient to
permit the Trust to make full quarterly distributions on the Series A Preferred
Securities.
    
 
OWNERSHIP LIMIT NECESSARY TO MAINTAIN REIT QUALIFICATION
 
   
     In order for the Trust to maintain its qualification as a REIT, not more
than 50% in value of its outstanding Trust Securities may be owned, directly or
indirectly, by five or fewer individuals (as defined in the Code). In this
regard, the Declaration generally prohibits ownership of more than 9.8% of the
outstanding Series A Preferred Securities by any holder. Any change in the
Ownership Limit would require an amendment
    
 
                                       18
<PAGE>   20
 
to the Declaration. Such an amendment to the Declaration would require the
affirmative vote of holders owning not less than two-thirds of the outstanding
Common Securities. Series A Preferred Securities have no voting rights with
respect to such an amendment.
 
     The constructive ownership rules of the Code are complex and may cause
Series A Preferred Securities owned, directly or indirectly, by a group of
related individuals and/or entities to be deemed to be constructively owned by
one individual or entity. As a result, the acquisition of less than 9.8% of the
Series A Preferred Securities of any series (or the acquisition of an interest
in an entity which owns Series A Preferred Securities) by an individual or
entity could cause that individual or entity (or another individual or entity)
to own constructively in excess of 9.8% of the Series A Preferred Securities,
and thus subject such stock to the Ownership Limit.
 
   
     Direct or constructive ownership in excess of the Ownership Limit would
cause the violative transfer or ownership to be void, and cause such securities
to be converted into Excess Preferred Securities (as defined herein), which have
limited economic rights. See "Description of Series A Preferred
Securities -- Restrictions on Ownership and Transfer of Series A Preferred
Securities."
    
 
   
SPECIAL EVENT REDEMPTION OF SERIES A PREFERRED SECURITIES
    
 
   
     Upon the occurrence and during the continuation of a Tax Event or
Investment Company Event, which may occur at any time, the Operating Partnership
shall, in certain circumstances, have the right to redeem the Series A Preferred
L.P. Units, in whole but not in part, in which event a series of Preferred
Securities having economic terms substantially similar to the Series A Preferred
L.P. Units would be redeemed in full. Accordingly, if the Series A Preferred
L.P. Units are redeemed in full, the Trust will redeem Series A Preferred
Securities in full at the Redemption Price. See "Description of the Series A
Preferred L.P. Units -- Redemption."
    
 
   
CONFLICTS OF INTEREST
    
 
   
     CONTROL OF THE COMPANY AND THE OPERATING PARTNERSHIP; INFLUENCE OF CERTAIN
DIRECTORS AND THE IRVINE COMPANY. The Irvine Company has the right to nominate
for election to the Board of Directors of the Company (any such person, an
"Irvine Company Board Representative") three members of such Board of Directors
so long as The Irvine Company, its stockholders or its affiliates beneficially
own at least 20% of the outstanding Common Stock of the Company (including for
these purposes shares issuable upon exercise of the right set forth in the
Partnership Agreement to exchange Common L.P. Units for shares of Common Stock
of the Company subject to the ownership limit provisions applicable to The
Irvine Company set forth in the Company's Articles of Incorporation). In the
event this ownership falls below 20% but is at least 15%, The Irvine Company has
the right to nominate two persons for election to the Board of Directors; and if
this ownership falls below 15% but is at least 10%, The Irvine Company has the
right to nominate one person for election to the Board of Directors. See
"Management -- Executive Officers and Directors." In addition, the Articles of
Incorporation and Bylaws of the Company (the "Bylaws") provide that a majority
of the total number of directors of the Company, including at least one Irvine
Company Board Representative, shall constitute a quorum for the transaction of
business and, except as provided below, that the affirmative vote of the
majority of the directors present at a meeting at which a quorum is present
shall be the act of all of the Board of Directors. Notwithstanding the
foregoing, the approval of directors of the Company representing more than 75%
of the Board of Directors as a whole (the "Required Directors") is required with
respect to certain actions, and certain matters relating to the Operating
Partnership require the approval of the holders of a majority of the Common L.P.
Units. See "Management -- Certain Rights of The Irvine Company with Respect to
the Company's Board of Directors." Accordingly, The Irvine Company will have
substantial influence over the affairs of the Operating Partnership, which
influence might not be consistent with the interests of other holders of L.P.
Units or the holders of the Series A Preferred Securities.
    
 
   
     The Company has adopted certain policies and entered into certain
agreements with The Irvine Company and Mr. Bren designed to eliminate or
minimize potential conflicts of interest. The Board of Directors of the Company
has adopted a policy and has provided in the Company's Bylaws that no
transaction between the
    
 
                                       19
<PAGE>   21
 
   
Company or the Operating Partnership on the one hand and The Irvine Company,
affiliates of The Irvine Company or Mr. Bren on the other hand may be entered
into without the approval of the Independent Directors Committee of the
Company's Board of Directors. Members of the Independent Directors Committee are
unaffiliated with The Irvine Company. In addition, the Independent Directors
Committee engages an independent consultant to assist it in evaluating all land
transactions with The Irvine Company. However, there can be no assurance that
these policies will be successful in eliminating the influence of such conflicts
and, if they are not successful, decisions could be made that might fail to
reflect fully the interests of the Operating Partnership.
    
 
   
     OTHER BUSINESS ACTIVITIES OF THE IRVINE COMPANY. The Irvine Company has
significant business interests in developed industrial, commercial and other
properties and in the future development of such properties on the Irvine Ranch,
the value of which exceeds the value of its aggregate interest in the Company
and the Operating Partnership. The feasibility and development of other
apartment communities by the Operating Partnership on the Irvine Ranch may be
affected by the feasibility and development of commercial, industrial and
residential for-sale properties by The Irvine Company on the Irvine Ranch. No
assurance can be given that The Irvine Company will not determine that certain
potential apartment community sites on undeveloped portions of the Irvine Ranch
should be developed as single family, for-sale homes or condominiums or as
industrial or commercial properties.
    
 
   
THE IRVINE COMPANY CONTROLS LAND DESIGNATION AND THE TIMING OF LAND DESIGNATION
PURSUANT TO THE LAND RIGHTS AGREEMENT; INABILITY OF THE IRVINE COMPANY TO
DELIVER ENTITLED PROPERTIES
    
 
   
     Purchases of properties by the Operating Partnership from The Irvine
Company under the Land Rights Agreement may be made only with the approval of a
majority of the Independent Directors Committee. The Irvine Company determines
which land is designated for apartment community development in accordance with
the Master Plan for the Irvine Ranch, and therefore which land is eligible for
purchase by the Operating Partnership pursuant to the Land Rights Agreement. No
assurance can be given that The Irvine Company will entitle land for development
of additional apartment communities at a rate consistent with prior development.
Before an apartment may be developed on the Irvine Ranch, the Irvine Company
must obtain Village Related Entitlements. The Irvine Company controls the
application for Village Related Entitlements and also has certain approval
rights with respect to the architectural design and physical layout of the
rental apartment communities. The applications for Village Related Entitlements
will be obtained independently by The Irvine Company. The discretionary nature
of approval for Village Related Entitlements, together with the variety of
concerns which may be raised by government officials and public interest groups
during the approval process, may adversely affect The Irvine Company's ability
to entitle future apartment sites and offer them to the Operating Partnership
for development. Thus, the Operating Partnership's ability to develop future
properties on the Irvine Ranch may be delayed, reduced or prevented.
    
 
   
EARLY TERMINATION OF THE EXCLUSIVE LAND RIGHTS AND NON-COMPETITION ARRANGEMENTS
WITH THE IRVINE COMPANY AND MR. BREN WOULD ADVERSELY AFFECT THE OPERATING
PARTNERSHIP
    
 
   
     The Irvine Company and Mr. Bren have agreed not to directly or indirectly
acquire or develop, or acquire an equity ownership interest in any entity that
has an ownership interest in, any apartment community, whether on or off the
Irvine Ranch. The prohibition on The Irvine Company and Mr. Bren from developing
apartment communities on the Irvine Ranch will terminate on July 31, 2020. The
Irvine Company and Mr. Bren will remain prohibited from engaging in any such
activity off the Irvine Ranch until the following two conditions are satisfied:
(i) no nominee of The Irvine Company is a member of the Company's Board of
Directors and (ii) The Irvine Company and certain related persons beneficially
own less than 20% of the outstanding Common Stock of the Company in the
aggregate (including for these purposes shares of Common Stock issuable upon
exchange of its Common L.P. Units pursuant to the Exchange Rights, subject to
the ownership limit provision applicable to The Irvine Company under the
Company's Articles of Incorporation). As of December 1, 1997, The Irvine Company
owned 1,378,385 shares of Common Stock of the Company and 24,512,046 Common L.P.
Units exchangeable for Common Stock of the Company on a one-for-one basis,
subject to adjustment. The Land Rights Agreement may be terminated earlier upon
the
    
 
                                       20
<PAGE>   22
 
   
occurrence of any of the following events, none of which are within the control
of The Irvine Company: (i) the failure of the shareholders of the Company to
elect as directors of the Company the number of directors The Irvine Company is
entitled to nominate, (ii) the failure of the Company's Board of Directors to
elect a person designated by The Irvine Company to fill a vacancy created by the
departure from the Board (for any reason) of a director designated by The Irvine
Company and (iii) during the period that The Irvine Company has the right to
nominate three persons to the Board of Directors of the Company, the provisions
of the Company's Articles of Incorporation and Bylaws requiring the approval of
the Required Directors to take certain actions are repealed, modified, or
amended without the prior written consent of The Irvine Company. If the Land
Rights Agreement is terminated as a result of the occurrence of one of these
events, the Operating Partnership would no longer have an option to acquire
apartment community land sites from The Irvine Company and The Irvine Company
and Mr. Bren would no longer be prohibited from acquiring or developing, or
acquiring an equity ownership interest in any entity that has an ownership
interest in, apartment communities on or off the Irvine Ranch in competition
with the Operating Partnership. Accordingly, the termination of the Land Rights
Agreement would likely have a material adverse effect on the future development
activities of the Operating Partnership on the Irvine Ranch. See
"Management -- Certain Rights of The Irvine Company with Respect to the
Company's Board of Directors."
    
 
   
POTENTIAL FOR ADDITIONAL DEBT FINANCING AND INCREASED LEVERAGE
    
 
   
     Where possible, the Operating Partnership seeks to use leverage to increase
the rate of return on its investments and to allow the Operating Partnership to
make more investments than it otherwise could. Such use of leverage presents an
element of risk in the event that the cash flow from the Properties is
insufficient to meet the Operating Partnership's debt service and other
obligations or to make distributions with respect to its partnership interests,
including the Series A Preferred L.P. Units. In addition, all debt and other
liabilities of the Operating Partnership would rank senior to the Series A
Preferred L.P. Units, with a prior claim on the assets of the Operating
Partnership. As of September 30, 1997, the Operating Partnership had
approximately $706.1 million of total liabilities reflected on the Operating
Partnership's balance sheet.
    
 
   
REAL ESTATE OPERATIONS AND DEVELOPMENT RISKS MAY ADVERSELY AFFECT THE OPERATING
PARTNERSHIP'S ABILITY TO MAKE DISTRIBUTIONS ON THE SERIES A PREFERRED L.P. UNITS
    
 
   
     GENERAL. Real property investments are subject to varying degrees of risk.
The investment returns available from equity investments in real estate depend
in large part on the amount of income earned and capital appreciation generated
by the related properties as well as the expenses incurred. If the Properties do
not generate revenue sufficient to meet operating expenses, including debt
service and capital expenditures, the Operating Partnership's income and ability
to service its debt and other obligations and to make distributions on its
partnership interests, including the Series A Preferred L.P. Units, will be
adversely affected. This in turn would adversely affect the Trust's ability to
make distributions on the Series A Preferred Securities. In addition, the
Properties consist primarily of apartment communities located in Orange County.
Income from and the performance of the Irvine Ranch Properties may therefore be
adversely affected by the general economic climate in Orange County, including
unemployment rates and local conditions such as the supply of and demand for
apartments in the area, the attractiveness of the Irvine Ranch Properties to
residents, zoning or other regulatory restrictions, competition from other
available apartments and alternative forms of housing, the affordability of
single family homes, the ability of the Operating Partnership to provide
adequate maintenance and insurance and the potential of increased operating
costs (including real estate taxes). Certain significant expenditures associated
with an investment in real estate (such as mortgage and other debt payments,
real estate taxes and maintenance costs) generally are not reduced when
circumstances cause a reduction in revenue from the investment. In addition,
income from properties and real estate values are also affected by a variety of
other factors, such as governmental regulations and applicable laws (including
real estate, zoning and tax laws), interest rate levels and the availability of
financing. The Irvine Ranch Properties in the aggregate historically have
generated positive cash flow from operations; however, no assurance can be given
that such will be the case in the future.
    
 
                                       21
<PAGE>   23
 
   
     In 1997, the Operating Partnership commenced an "off-Ranch" expansion
program through the acquisition of rights to purchase three apartment community
development sites located in Northern California's Silicon Valley. The Operating
Partnership commenced construction of a 342-unit apartment community on one of
such sites in May 1997 and on October 23, 1997, the Company's Board of Directors
authorized, subject to receipt of necessary entitlements, the acquisition of
another of the development sites. Construction of an apartment community of
approximately 155 units on this site is expected to commence in the first half
of 1998. On June 30, 1997, the Operating Partnership acquired an existing
923-unit apartment community located in Northern San Diego County. These new
Properties represent the Operating Partnership's first strategic expansion off
the Irvine Ranch and the Operating Partnership may make additional investments
in California in the future. The development, construction and operation of
rental apartment communities in such new markets may present risks different
from or in addition to the risks discussed above related to the Irvine Ranch
Properties, which are located entirely in Orange County. In addition, in
contrast to acquisitions of land pursuant to the Land Rights Agreement in which
a substantial portion of pre-development costs and expenses, including the cost
and expense of obtaining Village Related Entitlements, is borne solely by The
Irvine Company, all pre-development costs and expenses in connection with
"off-Ranch" expansion will be borne by the Operating Partnership and the
Operating Partnership will bear all risk relating to the failure to obtain
entitlements. For jurisdictions off the Irvine Ranch, local jurisdiction
approvals with respect to entitlements may impose requirements and conditions
different from those applicable to the Irvine Ranch. No assurance can be given
that the Operating Partnership will be successful in pursuing any additional
"off-Ranch" expansion or that any "off-Ranch" apartment communities will be
successful.
    
 
   
     Equity real estate investments, such as the investments made by the
Operating Partnership in the Properties and any additional properties that may
be developed or acquired by the Operating Partnership, are relatively illiquid.
Such illiquidity limits the ability of the Operating Partnership to vary its
portfolio in response to changes in economic or other conditions.
    
 
   
     The Properties are subject to all operating risks common to apartment
ownership in general. Such risks include: the Operating Partnership's ability to
rent units at the Properties, including the 1,110 units in the Communities Under
Construction; competition from other apartment communities; excessive building
of comparable properties which might adversely affect apartment occupancy or
rental rates; increases in operating costs due to inflation and other factors,
which increases may not necessarily be offset by increased rents; increased
affordable housing requirements that might adversely affect rental rates;
inability or unwillingness of residents to pay rent increases; and future
enactment of rent control laws or other laws regulating apartment housing,
including present and possible future laws relating to access by disabled
persons. If operating expenses increase, the local rental market may limit the
extent to which rents may be increased to meet increased expenses without
decreasing occupancy rates. If any of the above occurred, the Operating
Partnership's ability to meet its debt service and other obligations and to make
distributions on its partnership interests, including with respect to the Series
A Preferred L.P. Units, could be adversely affected.
    
 
   
     REAL ESTATE DEVELOPMENT AND ACQUISITION. A primary focus of the Operating
Partnership is on development of new apartment communities on sites acquired or
that may be acquired in the future primarily from The Irvine Company, although
the Operating Partnership also plans to develop new rental apartment communities
on sites acquired or that may be acquired in the future from third parties. The
Operating Partnership has also acquired and may continue to acquire completed
rental apartment communities. See "Recent Developments -- 'Off-Ranch'
Expansion." The real estate development business involves significant risks in
addition to those involved in the ownership and operation of established
apartment communities, including the risks that specific project approvals may
take more time and resources to obtain than expected, that construction may not
be completed on schedule or budget and that apartment communities may not
achieve anticipated rent or occupancy levels. In addition, if long-term debt or
equity financing is not available on acceptable terms to refinance new
development or acquisitions undertaken without long-term financing, further
development activities or acquisitions might be curtailed or cash available for
debt service and other obligations might be adversely affected.
    
 
   
     INSURANCE. The Operating Partnership carries comprehensive liability, fire,
extended coverage and rental loss insurance covering all of the Properties, with
policy specifications and insured limits which the Operating
    
 
                                       22
<PAGE>   24
 
   
Partnership believes are adequate and appropriate under the circumstances. There
are, however, certain types of losses (such as from earthquakes) that are not
generally insured because they are either uninsurable or not economically
insurable. The Operating Partnership does not carry earthquake insurance on any
of the Properties. Should an uninsured loss or a loss in excess of insured
limits occur, the Operating Partnership could lose its capital invested in the
Property, as well as anticipated future revenues from the Property and, in the
case of debt which is recourse to the Operating Partnership, would remain
obligated for any mortgage debt or other financial obligations related to such
Property. Any such loss would adversely affect the Operating Partnership. The
Operating Partnership believes that the Properties are adequately insured. In
addition, in light of the California earthquake risk, California building codes
since the early 1970s have established construction standards for all newly
built and renovated buildings, including apartment buildings, the current and
strictest construction standards having been adopted in 1984. Thirty-two of the
51 Existing Communities (representing approximately 68.9% of the units in the
Existing Communities) have been completed and occupied since January 1, 1985 and
the Operating Partnership believes that all of the Existing Communities were
constructed, and all of the Communities Under Construction are being
constructed, in full compliance with the applicable standards existing at the
time of construction. While earthquakes have occurred from time to time in
California, the Operating Partnership has not experienced any material losses as
a result of earthquakes. No assurance can be given that this will be the case in
the future.
    
 
CERTAIN PARTICIPATION RIGHTS OF THE IRVINE COMPANY
 
   
     The Irvine Company, unlike shareholders of the Company and holders of
Preferred L.P. Units, generally has the right to purchase shares of Common Stock
of the Company or securities convertible, exchangeable or exercisable for Common
Stock of the Company upon the issuance of such securities by the Company (for
cash or property) and also has the right to purchase Common L.P. Units upon the
issuance of additional Common L.P. Units by the Operating Partnership for cash
(but not for property) in order to maintain its percentage interest in the
Company and the Operating Partnership on a consolidated basis. Holders of Series
A Preferred L.P. Units will not have such purchase rights. See "Policies with
Respect to Certain Activities -- Operating Partnership -- Financing Policies"
and "Operating Partnership Agreement -- Issuance of Additional L.P. Units."
    
 
LACK OF PUBLIC MARKET
 
   
     The Series A Preferred Securities are a new issue of securities for which
there is currently no active trading market. If any of the Series A Preferred
Securities are traded after their initial issuance, they may trade at a discount
from their initial offering price, depending upon prevailing interest rates, the
market for similar securities and other factors, including general economic
conditions and the financial condition of, performance of, and prospects for,
the Operating Partnership. Although application has been made to list the Series
A Preferred Securities on the NYSE, there can be no assurance as to the
development of any market, or the liquidity of any market that may develop, for
the Series A Preferred Securities. If approved for listing, trading of the
Series A Preferred Securities on the NYSE is expected to commence within a
30-day period after the date of this Prospectus. The Underwriters have informed
the Trust that they intend to make a market in the Series A Preferred Securities
offered hereby; however, they are not obligated to do so and any such
market-making may be terminated at any time without notice to the holders of the
Series A Preferred Securities. See "Underwriting."

                               IAC CAPITAL TRUST
 
     The following description summarizes the material terms of the Declaration
and is qualified in its entirety by reference to the form of Declaration which
has been filed as an exhibit to the Registration Statement of which this
Prospectus forms a part.
 
   
     IAC Capital Trust is a statutory business trust formed on October 31, 1997
under the Business Trust Act pursuant to a declaration of trust among the
Trustees of the Trust, the Company and the Operating Partnership, and the filing
of a certificate of trust with the Secretary of State of the State of Delaware.
Such declaration will be amended and restated in its entirety (as so amended and
restated, the "Declaration") substantially in the form filed as an exhibit to
the Registration Statement of which this Prospectus forms a part, as of the date
the Series A Preferred Securities are initially issued. The Company and certain
members of management of the Company will acquire all of the Common Securities
of the Trust, for an aggregate consideration of $5,000. From time to time the
Trust may issue additional series of Preferred Securities and invest the
proceeds of any such issuance in an additional series of Preferred L.P. Units of
the Operating Partnership. The Trust Securities represent undivided beneficial
interests in the assets of the Trust, subject to the priority and payment terms
of the Trust Securities, and are not secured by any assets of the Operating
Partnership or any of its affiliates. Holders of Series A Preferred Securities
will have no voting rights, except in limited circumstances, and, except as
otherwise provided in the Declaration, the exclusive voting power for all
purposes (including with respect to amendments to the Declaration) shall be
vested in the holders of the Common Securities, including the exclusive right
(subject to the terms of the Declaration) to appoint, remove or replace the
Trustees and to increase or decrease the number of Trustees, subject to the
right of holders of any series of Preferred Securities upon whom such voting
rights have been conferred, including the Series A Preferred Securities, to
appoint for all series of Preferred Securities upon whom such voting rights have
been conferred and are then exercisable one additional Regular Trustee of the
Trust (a "Special Regular Trustee") in certain limited circumstances set forth
in this Prospectus. A Special Regular Trustee so appointed shall, without any
further act or vote by the holders of any series of Preferred Securities, be
deemed to have been appointed to act in such capacity for all series of
Preferred Securities upon which like voting rights have been conferred and are,
or in the future become, exercisable. A Special Regular Trustee need not be an
employee or officer of, or otherwise affiliated with, the Company. The Special
Regular Trustee shall have the same rights, powers and privileges under the
Declaration as the Regular Trustees. The Trust exists solely for the purpose of
(a) issuing one or more series of its Preferred Securities (and, if applicable,
Excess Preferred Securities), (b) issuing its Common Securities as described
above and investing the proceeds of such issuance in an interest bearing account
in, or certificate of deposit of, a banking institution, (c) investing the
proceeds from the sale of each series of Preferred Securities in a series of
Preferred L.P. Units of the Operating Partnership having economic terms
substantially identical to the series of Preferred Securities and (d) engaging
in such other activities as are necessary, convenient or incidental thereto. The
rights of the holders of the Trust Securities, including economic rights, rights
to information and voting rights, are set forth in the Declaration and the
Business Trust Act.
    
 
   
     The number of trustees (the "Trustees") of the Trust shall initially be
three. One or more of such Trustees (the "Regular Trustees") will be an
individual who is an officer of the Company. Initially, one Regular Trustee will
be appointed. The second trustee is The Bank of New York, which is unaffiliated
with the Company, the Operating Partnership and The Irvine Company and which
will serve as the property trustee (the "Property Trustee"). The third trustee
is an affiliate of The Bank of New York that has its principal place of business
in the State of Delaware (the "Delaware Trustee"). Pursuant to the Declaration,
legal title to each series of Preferred L.P. Units purchased by the Trust will
be held by the Property Trustee for the benefit of the holders of the Trust
Securities. In addition, the Property Trustee will maintain exclusive control of
one or more segregated non-interest bearing bank accounts (collectively, the
"Property Account") to hold, subject to the priority and payment terms of the
Preferred Securities, all payments in respect of the Preferred L.P. Units
purchased by the Trust for the benefit of the holders of the Preferred
Securities.
    
 
   
     The duties and obligations of the Trustees of the Trust shall be governed
by the Declaration. Under the Declaration, the Trust shall not, and the Trustees
shall cause the Trust not to, engage in any activity other than in connection
with the purposes of the Trust or other than as required or authorized by the
Declaration.
    
 
                                       24
<PAGE>   26
 
   
In particular, the Trust shall not and the Trustees shall not (a) invest any
amounts received by the Trust from holding the Preferred L.P. Units purchased by
the Trust but, shall promptly deposit such funds in the Property Account; (b)
acquire any assets other than as expressly provided in the Declaration; (c)
possess Trust property for other than a Trust purpose; (d) make any loans or
investments other than investments represented by the Preferred L.P. Units and
in connection with the investment of the proceeds of the sale of the Common
Securities as described above; (e) issue any securities or other evidences of
beneficial ownership of, or beneficial interests in, the Trust other than the
Trust Securities; or (f) incur any indebtedness for borrowed money.
    
 
     The books and records of the Trust will be maintained at the principal
office of the Trust and will be open for inspection by a holder of Preferred
Securities or its representative for any purpose reasonably related to its
interest in the Trust during normal business hours.
 
   
     Pursuant to the Declaration and, subject to the rights of holders of any
series of Preferred Securities hereafter issued which may rank on parity with
the Series A Preferred Securities in respect of distributions, distributions on
the Series A Preferred Securities when, as and if declared by the Regular
Trustees, must be paid on the dates payable to the extent that the Property
Trustee has cash on hand in the Property Account to permit such payment. So long
as the Series A Preferred L.P. Units are the only assets of the Trust, the funds
available for distribution to the holders of the Series A Preferred Securities
will be limited to payments received by the Property Trustee in respect of the
Series A Preferred L.P. Units that are deposited in the Trust as trust assets.
If the Preferred Securities of a series are called for redemption or are to be
repaid upon their stated maturity or upon liquidation, dissolution, winding-up
or termination of the Trust, the Property Trustee shall, subject to the priority
and payments terms of the Trust Securities, on the applicable redemption or
repayment date, pay to the holders of such series of Preferred Securities out of
funds deposited in the Property Account the amount specified in the terms of
such series of Preferred Securities to be paid on such date in accordance with
the terms of the Declaration and of such series of Preferred Securities. If the
Operating Partnership does not make distribution and other payments on the
Preferred L.P. Units deposited in the Trust as trust assets, including the
Series A Preferred L.P. Units, for any reason, it is expected that the Trust
will not be able to make distributions and other payments on the Series A
Preferred Securities. The Trust will terminate on December 31, 2092, the
termination date of the Operating Partnership, but may terminate earlier as
provided in the Declaration.
    
 
   
     The Declaration provides that the Trustees may treat the person in whose
name a certificate representing the Preferred Securities of a series is
registered on the books and records of the Trust as the sole holder thereof and
of the Preferred Securities represented thereby for purposes of receiving
distributions and payments on redemption or liquidation of the Trust and for all
other purposes and, accordingly, shall not be bound to recognize any equitable
or other claim to or interest in such certificate or in the Preferred Securities
represented thereby on the part of any person, whether or not the Trust shall
have actual or other notice thereof. Preferred Securities of a series will be
issued in fully registered form. The Series A Preferred Securities will be
represented by a global certificate registered on the books and records of the
Trust in the name of DTC or its nominee. Under the Declaration:
    
 
   
          (i) the Trust and the Trustees shall be entitled to deal with the DTC
     (or any successor depositary) for all purposes, including the payment of
     distributions and payments on redemption or liquidation of the Trust and
     receiving approvals, votes or consents under the Declaration, and except as
     set forth in the Declaration with respect to the Property Trustee, shall
     have no obligation to persons owning a beneficial interest in Series A
     Preferred Securities ("Preferred Security Indirect Owners") registered in
     the name of and held by the DTC or its nominee; and
    
 
   
          (ii) the rights of Preferred Security Indirect Owners shall be
     exercised only through the DTC (or any successor depositary) and shall be

its Trustees and any taxes and all costs and expenses with respect thereto, to
which the Trust may become subject, except with respect to distributions on the

                              RECENT DEVELOPMENTS
 
"OFF-RANCH" EXPANSION
 
     The Operating Partnership's intent is to develop or acquire new apartment
communities in the Silicon Valley and Northern San Diego County and other
locations in California which the Operating Partnership believes possess rental
demographics and economic growth prospects similar to those on the Irvine Ranch.
On October 23, 1997 the Board of Directors of the Company authorized the
Operating Partnership, subject to receipt of necessary entitlements, to exercise
an option for a land site located in Redwood City, California. Construction of
an apartment community of approximately 155 units on this site is expected to
commence in the first half of 1998. The site is located just off Highway 101
(the Bayshore Freeway), approximately midway between San Jose and San Francisco,
and is immediately adjacent to the 20 million square foot San
Mateo/FosterCity/Redwood City office market, in which headquarter facilities for
Oracle, Visa, Franklin Funds and Genentech are located. Preliminary design and
jurisdictional approvals are also in process with respect to the remaining
development site.
 
     On June 30, 1997, the Operating Partnership acquired for $127 million an
existing 923-unit apartment community, known as The Villas of Renaissance,
located in Northern San Diego County. Situated in La Jolla, California, the
project is located in University Town Center ("UTC") and enjoys free access from
the La Jolla Village Road/Interstate 805 interchange. The property is within
walking distance of 4.3 million square feet of office buildings in the UTC
financial district and the 1.3 million square foot UTC regional shopping mall
that is anchored by Nordstrom's, Macy's, Sears and Robinsons-May.
 
   
     In early December, 1997, the Operating Partnership completed the purchase
of two development sites located in San Diego county. The first site which was
purchased for cash is located on La Jolla Village Drive in the University Town
Center region of greater La Jolla. Construction of an apartment community of
approximately 232 units is expected to commence in mid-1998. The second site is
located in the master-planned community of Stonecrest Village in the Mission
Valley/Kearney Mesa region of San Diego county. Construction of an approximately
336-unit apartment community is scheduled to commence in early 1998, subject to
receipt of necessary entitlements. This site was acquired from an affiliate of
The Irvine Company controlled by Donald Bren, the Chairman of the Board of
Directors of the Company, in exchange for 305,707 Common L.P. Units. See
"Certain Relationships and Related Transactions -- Transactions with The Irvine
Company."
    
 
   
RECENTLY COMPLETED IRVINE RANCH LAND ACQUISITIONS
    
 
   
     On October 21, 1997, the Operating Partnership acquired a 196-unit
development site from The Irvine Company pursuant to the Land Rights Agreement.
On December 16, 1997 the Operating Partnership acquired from The Irvine Company
a 393-unit development site pursuant to the Land Rights Agreement.
    
 
ISSUANCE OF 7% NOTES DUE 2007
 
   
     On October 1, 1997, the Operating Partnership issued $100,000,000 aggregate
principal amount of 7% Notes due 2007 (the "7% Notes"). The Operating
Partnership used the net proceeds from the issuance of the 7% Notes to repay
outstanding borrowings under the Operating Partnership's $250 million revolving
credit facility (the "Credit Facility"), most of which was incurred in
connection with the Villas of Renaissance Acquisition.

                                USE OF PROCEEDS
 
   
     The proceeds from the sale of the Series A Preferred Securities will be
$150.0 million ($172.5 million if the Underwriters' overallotment option is
exercised in full). Such proceeds will be invested by the Trust in Series A
Preferred L.P. Units of the Operating Partnership. After paying the
Underwriters' Compensation and estimated expenses associated with the Offering,
the net proceeds to the Operating Partnership from the issuance of the Series A
Preferred L.P. Units are estimated to be $144.6 million ($166.4 million if the
Underwriters' overallotment option is exercised in full). The Operating
Partnership will use such net proceeds to repay indebtedness outstanding under
the Credit Facility and for general partnership purposes, including ongoing
development activities on and off the Irvine Ranch and the possible acquisition
of additional properties off the Irvine Ranch. Pending such use, the net
proceeds to the Operating Partnership will be invested in income-producing
short-term investments. On a pro forma basis after giving effect to the
repayment of indebtedness from the net proceeds of the offering of the 7% Notes,
as of September 30, 1997, $36.7 million would have been outstanding under the
Credit Facility with an average interest rate of 6.20% and, as of November 30,
1997, the Credit Facility had an outstanding balance of approximately $65.0
million. Indebtedness under the Credit Facility was incurred primarily to
finance the Villas of Renaissance Acquisition and for general partnership
purposes. The Company expects to use future borrowings under the Credit Facility
for general partnership purposes, including those described above.
    
 
            OPERATING PARTNERSHIP CONSOLIDATED RATIOS OF EARNINGS TO
              FIXED CHARGES AND PREFERRED L.P. UNIT DISTRIBUTIONS
 
     The following table sets forth the consolidated ratios of earnings to fixed
charges for the Operating Partnership.

Ratio of Earnings to Fixed
  Charges...........................  2.42x     2.00x     2.07x     1.44x     1.25x     .99x     .96x
</TABLE>
 
   
     For the purpose of calculating the ratio of earnings to fixed charges,
earnings consist of net earnings before income taxes, extraordinary items and
fixed charges. Fixed charges consist of interest expense, capitalized interest
and amortization of deferred financing costs. The ratios are computed using the
amounts for the Operating Partnership, on a consolidated basis, including its
majority owned subsidiary. The Operating Partnership did not have any Preferred
L.P. Units outstanding in any of the periods indicated, and, therefore, the
ratio of earnings to combined fixed charges and Preferred L.P. Unit
distributions for each of the periods indicated was equal to the ratio of
earnings to fixed charges for such period. The Trust did not have any operations
in any of the periods indicated, and, therefore, the historical ratio with
respect to the Trust is not applicable. On a pro forma basis, the ratio of
earnings to combined fixed charges and preferred securities distributions of the
Trust is expected to be 1.00x.
    
 
     Prior to completion of the Company's Initial Public Offering in December
1993, the Predecessor of the Company and the Operating Partnership operated in a
highly leveraged manner. As a result, although the Company, the Operating
Partnership and the Predecessor have historically generated positive net cash
flow, the financial statements of the Predecessor showed net losses for the
periods prior to December 8, 1993. Consequently, the computations of the ratio
of earnings to fixed charges for such periods indicate that earnings were
inadequate to cover fixed charges by approximately $0.6 million and $2.2 million
for the years ended December 31, 1993 and 1992, respectively.

                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                          OF THE OPERATING PARTNERSHIP
 
   
     The following discussion should be read in conjunction with the "Selected
Consolidated Financial Data," the Operating Partnership's Consolidated Financial
Statements and the Notes thereto for the years ended December 31, 1996, 1995 and
1994 (the "OP Audited Financial Statements") and the Operating Partnership's
Unaudited Condensed Consolidated Financial Statements and the Notes thereto for
the nine months ended September 30, 1997 and 1996 (the "OP Unaudited Quarterly
Financial Statements").
    
 
OVERVIEW
 
   
     The Operating Partnership is engaged in the development and operation of
multifamily rental apartment communities in California. The Operating
Partnership's management and operating decisions are under the unilateral
control of the Company. The Company operates as a REIT under the Code. As of
September 30, 1997, the Operating Partnership owned and operated 55 Properties
containing 14,991 apartment units and had 1,110 units under construction. Until
July 31, 2020, the Operating Partnership has the exclusive right, but not the
obligation, to acquire land from The Irvine Company for development of
additional apartment communities on the Irvine Ranch. See Note 7 to the OP
Audited Financial Statements.
    
 
     At September 30, 1997, the Company had a 45.2% general partnership interest
in and was the sole managing general partner of the Operating Partnership, which
began operations as of December 8, 1993, the date of the Company's Initial
Public Offering. In connection with the Initial Public Offering, The Irvine
Company transferred 42 apartment communities and a 99% interest in a limited
partnership which owned one apartment community to the Operating Partnership. At
September 30, 1997, the limited partners of the Operating Partnership had a
54.8% limited partner interest with The Irvine Company and its affiliates having
a 54.6% limited partnership interest in the Operating Partnership.
 
     The Trust did not have any operations prior to October 31, 1997.
 
RESULTS OF OPERATIONS
 
     Nine months ended September 30, 1997 compared to nine months ended
September 30, 1996. The Operating Partnership's net income was $43.0 million for
the nine months ended September 30, 1997, up from $28.9 million for the same
period of 1996. The improvement was due to the contribution of new rental units
from the Operating Partnership's acquisition and development program, as well as
an increase in revenues within its stabilized portfolio achieved through higher
rental rates slightly offset by lower occupancy and higher operating expenses.

(a) Represents "same store" communities.
 
(b) Represents five communities that began leasing in 1995 and reached
    stabilized occupancy (95%) at various dates in 1996.
 
   
(c) Represents Baypointe and Santa Maria communities that began leasing in 1996,
    completed deliveries in June 1997, and reached stabilized occupancy (95%) in
    July 1997 and The Villas of Renaissance (see Note 6 to the OP Unaudited
    Quarterly Financial Statements), an apartment community acquired by the
    Operating Partnership on June 30, 1997.
    
 
     Operating revenues (rental and other income) increased to $136.2 million in
the first nine months of 1997, up from $116.3 million in the same period of
1996. Operating revenues rose as a result of higher occupancy and rental rates,
as well as the contribution of newly delivered rental units from five properties
which achieved stabilization during 1996, a newly acquired community and two new
lease-up communities. In total, these new units added $31.7 million to operating
revenues in the first nine months of 1997 compared to $17.2 million in the first
nine months of 1996. Within communities owned and stabilized more than two
years, operating revenues increased 5.4% from the first nine months of 1996, as
a result of improvement in average monthly rental rates and higher non-rental
income, slightly offset by a decrease in physical occupancy to 94.5% from 94.8%.
Average monthly rental rates increased to $1,068 in the first nine months of
1997 from $1,007 in the year-earlier period. Healthy job growth in the Operating
Partnership's marketplace has been a key factor in the upward trend in rental
rates.
 
                                       33
<PAGE>   35
 
     Property expenses increased to $28.8 million in the first nine months of
1997 from $24.9 million in the first nine months of 1996. This increase reflects
the added expenses of newly delivered rental units from five properties which
achieved stabilization during 1996, a newly acquired community and two new
lease-up communities. Property expenses within communities owned and stabilized
more than two years increased by $1.7 million to $23.5 million in the first nine
months of 1997 from $21.8 million a year ago. In the first nine months of 1997,
average monthly property expenses at these Properties increased to $231 per unit
from $214 per unit in the first nine months of 1996, primarily as a result of
higher unit turnover and related expenses in addition to preventative
maintenance scheduled in preparation for a potentially unseasonably wet winter.
Properties stabilized less than two years added $3.7 million to property
expenses in the first nine months of 1997 and $3.1 million in the first nine
months of 1996. Lease-up and newly acquired properties added $1.6 million to
property expenses in the first nine months of 1997.
 
     Real estate taxes totaled $11.0 million in the first nine months of 1997
compared to $10.0 million in the first nine months of 1996. Taxes increased in
the first nine months of 1997 due to the addition of rental units from lease-up
properties and an acquisition.
 
     Property management fees increased to $3.8 million in the first nine months
of 1997 from $3.3 million in the first nine months of 1996. Management fees
increased in the first nine months of 1997 due to the addition of rental units
from development, an acquisition and an increase in revenue from communities
owned and stabilized more than two years.
 
     Net interest expense decreased to $21.9 million in the first nine months of
1997 from $22.4 million for the same period of 1996. The decrease was largely
due to a greater amount of capitalized interest during the 1997 period partially
offset by a higher level of borrowings under the Credit Facility. The Operating
Partnership capitalizes interest on projects actively under development using
average qualifying asset balances and applicable weighted average interest
rates. The average monthly qualifying asset balances for projects under
development in the first nine months of 1997 and 1996 were approximately $66.0
million and $39.7 million, respectively. Interest capitalized totaled $3.7
million in the first nine months of 1997 compared to $2.3 million in the same
period of 1996. Interest incurred was $25.6 million and $24.7 million for the
first nine months of 1997 and 1996, respectively.
 
     Amortization of deferred financing costs was comparable in the first nine
months of 1997 and 1996.
 
     Depreciation and amortization expense increased to $21.7 million in the
first nine months of 1997, up from $20.3 million in the first nine months of
1996. This increase reflects the completion and delivery of newly developed
rental units from the Operating Partnership's lease-up properties and an
acquisition.
 
     General and administrative expense of $4.8 million was comparable to the
same nine month period of the prior year.
 
     Years Ended December 31, 1996, 1995 and 1994. The Operating Partnership's
income before extraordinary item was $41.2 million in 1996, up from $25.1
million in 1995 and $12.3 million in 1994. The Operating Partnership's financial
results improved in 1996 due to the contribution of newly delivered rental units
from its development program, cost reductions and an increase in revenues within
its stabilized portfolio achieved primarily through higher occupancy and higher
rental rates. In 1995, financial results improved largely as a result of the
contribution of newly delivered rental units and operating cost reductions
within the Operating Partnership's stabilized portfolio.

- ---------------
 
(a) Represents five communities that began leasing in 1995 and reached
    stabilized occupancy (95%) at various dates in 1996.
 
     Operating revenues (rental and other income) increased by 16.4% to $158.1
million in 1996, up from $135.8 million in 1995. Operating revenues in 1995 had
increased by 5.3% from $128.9 million in 1994. Operating revenues rose in 1996
as a result of higher occupancy, higher rental rates and the contribution of
newly delivered rental units from five properties which achieved stabilization
during 1996. In total, these new units added $24.7 million to operating revenues
in 1996, compared to $5.7 million in 1995. Within communities stabilized more
than two years, operating revenues increased 2.5% in 1996, primarily due to
increases in rental rates and an increase in average physical occupancy to 95.0%
from 94.6% in 1995. Average monthly rental rates per unit increased 1.9% to
$1,015 in 1996, from $996 in 1995.
 
     Operating revenues improved in 1995 from the prior year largely as a result
of the contribution of newly delivered rental units. In total, these new units
added $5.7 million to operating revenues in 1995. They made virtually no
contribution in 1994. Within communities stabilized more than two years,
operating revenues increased less than 1% in 1995, as modest increases in rental
rates were largely offset by a decline in average physical occupancy to 94.6%
from 95.6% in 1994. Average monthly rental rates per unit increased 1.5% to $996
in 1995, from $981 in 1994.
 
     Property expenses increased by 6.6% to $33.9 million in 1996 from $31.8
million in 1995. These expenses had decreased in 1995 by 4.1% from $33.1 million
in 1994. The increase in 1996 reflects the added expenses of
 
                                       35

newly delivered rental units from five properties which achieved stabilization
during 1996. Property expenses within communities stabilized more than two years
decreased 2.8% to $29.5 million in 1996 from $30.3 million in 1995. During the
three years ended December 31, 1996, the Operating Partnership achieved
sustained reductions in its per-unit property expenses through aggressive
bidding of external service and purchase contracts and a series of initiatives
to enhance the efficiency of customer service and property maintenance
operations. In 1996, average monthly property expenses within communities
stabilized more than two years decreased to $217 per unit from $223 per unit in
1995 and $243 per unit in 1994. Properties stabilized less than two years added
$4.4 million to property expenses in 1996 and $1.4 million in 1995.
 
     Real estate taxes totaled $13.5 million in 1996, $12.0 million in 1995 and
$11.8 million in 1994. Taxes increased in 1996 due to the addition of rental
units, partially offset by a reduction in assessed values. In 1995, the
Operating Partnership's real estate taxes increased from the 1994 level due to
the addition of rental units.
 
     Property management fees increased to $4.5 million in 1996 from $3.9
million in 1995 and $3.8 million in 1994. Management fees increased in 1996 and
1995 due to the addition of rental units and an increase in revenue from
communities stabilized more than two years.
 
     Net interest expense increased to $29.5 million in 1996 from $25.9 million
in 1995 and $26.8 million in 1994. The increase in 1996 net interest expense was
due to new properties being placed in service. The Operating Partnership
capitalizes interest on projects actively under development using qualifying
asset balances and applicable weighted average interest rates. Capitalized
interest totaled $3.2 million in 1996 compared to $6.8 million in 1995 and $1.3
million in 1994. In 1995, net interest expense decreased $0.9 million from the
prior year primarily due to a higher level of capitalized interest resulting
from increased construction activity, offset by higher interest incurred as a
result of the May 1995 refinancing of tax-exempt mortgage debt and increased
borrowings under bank lines of credit. Total interest incurred was $32.7 million
in 1996 and 1995, and $27.6 million in 1994.
 
     Interest income totaled $0.6 million in 1996, $0.4 million in 1995 and $1.3
million in 1994. The changes in interest income reflect changes in the Operating
Partnership's average cash balances.
 
     Amortization of deferred financing costs decreased by 69.1% to $2.6 million
in 1996 from $8.5 million in 1995 and $15.9 million in 1994. The $5.9 million
decrease in 1996 and $7.4 million decrease in 1995 were largely due to the
elimination of deferred financing costs through an extraordinary charge of $23.4
million related to the refinancing of tax-exempt mortgage debt in May 1995.
 
     Depreciation and amortization expense increased by 17.7% to $27.2 million
in 1996, up from $23.1 million in 1995. These expenses had increased in 1995 by
9.9% from $21.1 million in 1994. The increases in both years reflect the
completion and delivery of newly developed rental units.
 
     General and administrative expense increased to $6.3 million in 1996, up
from $5.9 million in 1995. General and administrative expense had increased in
1995 from $5.4 million in 1994. These increases were largely the result of
increased staffing levels.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Operating Partnership believes that cash provided by operations will be
adequate to meet both operating requirements and payment of distributions on its
G.P. Units and L.P. Units in both the short and long term.
 
     Liquidity. The Operating Partnership expects to meet its long-term
liquidity requirements, such as construction, scheduled debt maturities and
potential future property acquisitions, through the issuance or refinancing of
long-term debt, borrowings from financial institutions, or the issuance of
additional equity securities of the Company and/or L.P. Units. On June 27, 1997,
the Operating Partnership renewed its $250 million unsecured Credit Facility for
a three-year term. The new Credit Facility currently bears interest at LIBOR
plus 0.70% or prime. The Credit Facility provides for the borrowing interest
rates to be adjusted up or down reflecting the credit ratings on the Operating
Partnership's senior unsecured long-term indebtedness.
 
                                       36
<PAGE>   38
 
Availability under the Credit Facility was $115 million at September 30, 1997
($213.3 million after giving effect to the repayment of outstanding borrowings
with the net proceeds from the issuance of the 7% Notes).
 
   
     Additional Equity. On February 20, 1997 the Company sold, in a public
offering, 1.15 million shares of Common Stock at $27.50 per share, the proceeds
of which were contributed to the Operating Partnership for an additional general
partnership interest. Concurrently, The Irvine Company, pursuant to its rights
under the Partnership Agreement, purchased 1.39 million additional Common L.P.
Units at $26.06 per unit (which is equal to the public offering price of the
Common Stock less an amount equivalent to the underwriting discount) which are
exchangeable for Common Stock on a one for one basis, subject to adjustment and
certain limitations. The proceeds from the two transactions totaled
approximately $66.0 million and were used by the Operating Partnership to repay
all then outstanding indebtedness under its revolving line of credit, and for
general partnership purposes, including development of new apartment
communities.
    
 
   
     Shelf Registration Statements. On May 14, 1997 the Company filed a shelf
registration statement with the Securities and Exchange Commission providing for
the issuance from time to time of up to $350 million of common stock, preferred
stock, debt securities, and warrants to purchase common stock, preferred stock
and debt securities. Concurrently, the Operating Partnership filed a shelf
registration statement with the Commission providing for the issuance from time
to time of up to $350 million of debt securities. Proceeds raised from any
securities issued under the Company's shelf registration statement will be
contributed to the Operating Partnership and such proceeds, together with any
proceeds raised from any securities issued under the Operating Partnership's
shelf registration statement will be used for general partnership purposes,
including the development of new apartment communities, acquisitions and the
repayment of existing debt. On October 1, 1997 the Operating Partnership issued
$100 million aggregate principal amount of 7% Notes. Net proceeds of $98.3
million were used to repay indebtedness under the Credit Facility that had been
incurred primarily to finance the Villas of Renaissance Acquisition. See Note 6
to the OP Unaudited Quarterly Financial Statements.
    
 
     Debt. The Operating Partnership's conventional and tax-exempt mortgage debt
bears interest at fixed interest rates, or variable rates that have been
effectively fixed through interest rate swap agreements. Interest rates on
conventional mortgage debt were reduced to then-current market rates at the time
of the Company's December 1993 Initial Public Offering through interest rate
buy-down agreements that are scheduled to expire at various dates prior to loan
maturity. A buy-down agreement relating to $35.8 million of conventional debt
expired in September 1997, and as a result, the interest rate on that loan
increased from 5.82% to 8.30%. The weighted average effective interest rate on
the Operating Partnership's debt, including the non-cash charges of amortization
of deferred financing costs, was 6.44% at September 30, 1997. The Operating
Partnership uses interest rate swap agreements to effectively convert its
floating rate tax-exempt mortgage bond financings to a fixed-rate basis, thus
reducing the impact of fluctuations in interest rates on future income.

     Operating Activities. Cash flow provided by operating activities was $69.4
million and $55.7 million in the first nine months of 1997 and 1996,
respectively. Cash provided by operating activities increased in 1997 primarily
due to higher revenues from newly developed and acquired apartment units, as
well as an increase in revenues within the Operating Partnership's stabilized
portfolio achieved through higher rental rates. Cash flow provided by operating
activities was $73.0 million, $55.4 million and $49.8 million for the years
ended 1996, 1995 and 1994, respectively. Cash provided by operating activities
increased in 1996 and 1995 compared to prior years primarily due to higher
revenues and lower per-unit operating costs in the Operating Partnership's
stabilized portfolio.
    
 
   
     Investing Activities. Cash flow used in investing activities was $205.8
million and $44.2 million in the first nine months of 1997 and 1996,
respectively. This increase resulted from increased development activity in the
first nine months of 1997 (see "-- Capital Expenditures" below), and the
acquisition of The Villas of Renaissance (see Note 6 to the OP Unaudited
Quarterly Financial Statements). Cash flow used in investing activities was
$66.6 million, $128.2 million and $50.9 million for the years ended 1996, 1995
and 1994, respectively. Changes in levels of cash flows used in investing
activities for each year reflect the changing levels of real estate development
by the Operating Partnership. See "-- Capital Expenditures."
    
 
   
     Financing Activities. Cash flow provided by (used in) financing activities
was $135.5 million and ($8.4) million in the first nine months of 1997 and 1996,
respectively. The Operating Partnership received an aggregate of approximately
$66.0 million from the sale of Common L.P. Units and the contribution by the
Company of the proceeds from the sale of its Common Stock in the first quarter
of 1997. See "-- Additional Equity" above. These proceeds were used to pay down
borrowings from the lines of credit. In June 1997, the Operating Partnership
borrowed $118 million under the Credit Facility to fund the acquisition of The
Villas of Renaissance. Additionally, the Operating Partnership paid $47.5
million in distributions on its G.P. Units and Common L.P. Units in the first
nine months of 1997, compared to $41.3 million in the first nine months of 1996.
Cash flow provided by (used in) financing activities was $(7.6) million, $73.7
million and $(23.3) mil-

lion for the years ended 1996, 1995 and 1994, respectively. Among the factors
affecting these cash flows in 1996, the Operating Partnership received an
aggregate of approximately $60.0 million from the sale of Common L.P. Units and
the contribution by the Company of the proceeds from the sale of its Common
Stock, compared to $109.3 million in 1995. These proceeds were used to pay down
borrowings from the line of credit. In 1995, the Operating Partnership received
$8.3 million of additional proceeds from the refinancing of tax-exempt debt,
while incurring loan origination costs of $9.2 million and net borrowings from
the line of credit of $15.7 million. Distributions paid on its G.P. Units and
Common L.P. Units in 1996 increased to $56.1 million from $44.8 million in 1995.
In 1994, cash flows used in financing activities included $33.6 million in
distributions paid on its G.P. Units and Common L.P. Units, partially offset by
new borrowings in excess of principal reductions of approximately $11.1 million
and net borrowings from the line of credit of $6.3 million.
 
CAPITAL EXPENDITURES
 
     Capital Expenditures on New Development. The Operating Partnership's major
cash requirements in the next twelve months are expected to be for the
construction of new apartment communities and possibly for acquisitions of
apartment communities. Currently, the Operating Partnership has four apartment
communities under development (The Colony, Santa Rosa II, Rancho Santa Fe and
The Hamptons) that will require total expenditures of approximately $162
million, of which $102 million had been incurred at September 30, 1997. Funding
for these developments came from, and funding for future development activities
is expected to come from, the Credit Facility and the proceeds from this
Offering. The Company or the Operating Partnership may issue other debt or
equity securities as discussed above under "-- Liquidity and Capital Resources."

     The timing of future construction, leasing activities and initial
stabilized occupancy and estimated costs of apartment communities that are in
development are only estimates. Actual results will depend on numerous factors,
many of which are beyond the control of the Operating Partnership. These include
the extent and timing of economic growth in the Company's rental markets; future
trends in the pricing of construction materials and labor; entitlement decisions
by local government authorities; weather; changes in interest rate levels; and
other changes in capital markets. No assurance can be given that the timing or
estimates set forth in the foregoing table will not vary substantially from
actual results.
 
     Capital Replacements on Stabilized Properties. Expenditures for capital
replacements totaled $3.2 million and $2.9 million in the first nine months of
1997 and 1996, respectively. Average capital replacements per unit for
communities owned and stabilized more than two years increased to $275 from $254
in the first nine months of 1997 and 1996, respectively, due to the nature and
timing of scheduled capital programs. Expenditures for capital replacements in
1997 are expected to be similar to 1996 levels. Expenditures for capital
replacements within communities stabilized more than two years totaled $4.7
million, $4.5 million and $5.6 million in 1996, 1995 and 1994, respectively.
Average capital replacements per unit within communities stabilized more than
two years were $415, $399 and $490 in 1996, 1995 and 1994, respectively.
Overall, these expenditures declined over this period reflecting greater
efficiency in property enhancement activities, including centralized purchasing
of major replacement materials. The Operating Partnership has a policy of
capitalizing expenditures related to asset acquisitions, costs which increase
the value of an existing asset, or
 
                                       39

replacements for communities stabilized more than two years were as follows:

     The Operating Partnership also plans to incur approximately $5.2 million in
capital expenditures over the next two years at one of its existing apartment
communities, Promontory Point. Management believes that these capital
expenditures will generate additional revenue by enhancing the community's
appeal in the luxury segment of the marketplace. In addition, the Operating
Partnership plans to incur approximately $5.0 million in capital expenditures of
which $0.4 million had been incurred through September 30, 1997 at The Villas of
Renaissance which was acquired on June 30, 1997 (see Note 6 to the OP Unaudited
Quarterly Financial Statements). The Operating Partnership believes these
capital expenditures will generate additional revenue by enhancing the apartment
community's appeal within the luxury segment of the marketplace. Funding for
these expenditures is expected to come from the Credit Facility and proceeds of
this Offering.
    
 
IMPACT OF INFLATION
 
     The Operating Partnership's business is affected by general economic
conditions, including the impact of inflation and interest rates. Substantially
all of the Operating Partnership's leases allow, at time of renewal, for
adjustments in the rent payable thereunder, and thus may enable the Operating
Partnership to seek increases in rents. Substantially all leases are for a
period of one year or less. The short-term nature of these leases generally
serves to minimize the risk to the Operating Partnership of the adverse effects
of inflation. For construction, the Operating Partnership has entered into
various contracts for the development and construction of new apartment
communities. These are fixed-fee contracts and thus partially insulate the
Operating Partnership from inflationary risk.

              BUSINESS AND PROPERTIES OF THE OPERATING PARTNERSHIP
 
GENERAL
 
   
     The Operating Partnership is engaged in the development and operation of
multifamily rental apartment communities in California. The Operating
Partnership's management and operating decisions are under the unilateral
control of the Company, a self-administered equity real estate investment trust.
The Operating Partnership and the Company were formed in December 1993 to
continue and expand the apartment community business of The Irvine Company, a
real estate and community development company. At September 30, 1997, the
Company had a 45.2% (44.4% at December 16, 1997) general partnership interest in
the Operating Partnership and was its sole managing general partner. At such
date, the limited partners of the Operating Partnership had a 54.8% (55.6% as of
December 16, 1997) interest in the Operating Partnership, represented by the
Common L.P. Units, with The Irvine Company and certain of its affiliates owning
a 54.6% (55.4% as of December 16, 1997) limited partnership interest in the
Operating Partnership.
    
 
     As of September 30, 1997, the Operating Partnership owned and operated
14,991 units in 51 Existing Communities and had four additional Communities
Under Construction aggregating 1,110 units. Upon completion of the Communities
Under Construction, the Operating Partnership will own a total of 16,101 units
in 55 apartment communities, representing an increase in units of approximately
42% since the Initial Public Offering in December 1993. Through July 2020, the
Company and the Operating Partnership hold the exclusive right, but not the
obligation, to acquire land from The Irvine Company, the owner and developer of
the Irvine Ranch since 1864, for development of additional apartment communities
on the Irvine Ranch. Fifty-three of the Properties aggregating 14,836 units (the
"Irvine Ranch Properties") are or will be located on the Irvine Ranch, of which
50 constitute Existing Communities (14,068 units) and three constitute
Communities Under Construction (768 units).
 
   
     In 1997, the Operating Partnership commenced an "off-Ranch" expansion
program through the acquisition of rights to purchase three apartment community
development sites located in Northern California's Silicon Valley. The Operating
Partnership has exercised its right with respect to one of these sites and has
begun construction on a 342-unit apartment community on the site. On October 23,
1997, the Board of Directors of the Company authorized the Operating
Partnership, subject to the receipt of necessary entitlements, to exercise
another of the options. Construction of an apartment community of approximately
155 units on this site is expected to commence in the first half of 1998.
Preliminary design and jurisdictional approvals are also in process with respect
to the remaining development site. In addition, on June 30, 1997, the Operating
Partnership purchased for $127 million the 923-unit Villas of Renaissance
located in Northern San Diego County. See "Recent Developments -- 'Off-Ranch'
Expansion." Two additional sites located in Northern San Diego County were
purchased in early December 1997. The Operating Partnership believes that the
economic expansion being experienced by the State of California provides the
Operating Partnership with significant growth potential beyond the Irvine Ranch.
    
 
     The Irvine Ranch is located in central Orange County, California between
San Diego and Los Angeles. The western boundary of the Irvine Ranch borders
approximately six miles of the Pacific Ocean. Today, the portion of the Irvine
Ranch which is still owned by The Irvine Company covers approximately 50,000
acres and includes the largest remaining privately-owned undeveloped acreage in
Orange County. The developed portion of the Irvine Ranch, which includes the
City of Irvine and significant parts of the cities of Newport Beach and Tustin,
is one of the largest urban master-planned communities in the United States. The
Irvine Ranch has been developed over the past 30 years in accordance the Master
Plan which, over time, has been refined to accord with locally approved general
plans. The Irvine Ranch is one of the major commercial, industrial, retail and
residential centers in Southern California.

     The Operating Partnership believes that a variety of factors have
contributed to the strong apartment market in Orange County, the successful
operating performance of the Existing Communities located on the Irvine Ranch
and the existence of significant opportunities for the development of additional
apartment communities on the Irvine Ranch. Most important among these factors
are:
 
     - The dominant market position of the Operating Partnership, which owns
       over 85% of all apartment communities having 100 or more units on the
       Irvine Ranch;
 
     - The Operating Partnership's 23-year exclusive right to acquire land from
       The Irvine Company for development of additional rental apartment
       communities on the Irvine Ranch;
 
     - The limited supply of developable land, other than on the Irvine Ranch,
       adjacent to major employment centers in Orange County;
 
     - The Irvine Company's Master Plan strategy which emphasizes market
       segmentation in order to ensure adequate and appropriate allocation of
       land uses which support sustained growth for the long-term;
 
     - The high quality of design, construction and maintenance of the Irvine
       Ranch Properties and their location in or near the City of Irvine, which
       was ranked by the Federal Bureau of Investigation as among the safest
       cities in the United States with a population of 100,000 or more;
 
     - The close proximity of the Irvine Ranch Properties and of future
       development sites to major employment centers, the Pacific Ocean, high
       quality schools, and extensive resort, recreational and open space
       amenities;
 
     - An affluent, growing population and diversified employment base in Orange
       County and on the Irvine Ranch;
 
     - The Operating Partnership's ability to defer the purchase of land on the
       Irvine Ranch under its land rights agreement until site and zoning
       entitlements have been obtained, the land is ready for construction and
       the Operating Partnership determines favorable market conditions exist;
 
     - The operating efficiencies available to the Operating Partnership because
       the Irvine Ranch Properties are located in a single geographic area;
 
     - An average of 20 years of experience of the Company's 11 most senior
       members of management in the design, development, construction, property
       management and financing of apartment communities; and
 
     - The effectiveness of management's policies regarding property management
       and expense control.
 
     The Operating Partnership's intent is to develop or acquire new apartment
communities in California. The Operating Partnership has recently commenced
operations in the Silicon Valley and Northern San Diego County, which possess
strong rental demographics and economic growth prospects similar to those on the
Irvine Ranch.
 
BUSINESS STRATEGY
 
     The Operating Partnership's primary business objective is to deliver
strong, consistent total annual returns to its partners while enhancing the
long-term growth in value of its real estate portfolio. The Operating
Partnership believes it is well positioned to meet this objective given the size
and strength of the economic regions in which it operates, the quality of its
existing apartment community portfolio and the significant opportunities for new
development within its primary market, and in similar high growth regions of
California, such as the Silicon Valley and the Northern San Diego marketplace.
Through adherence to specific operating and development strategies, the most
important of which are discussed below, the Operating Partnership seeks to
achieve growth in its funds available for distribution through maximization of
cash flow from its Existing Communities and the development of new apartment
communities.
 
                                       42
<PAGE>   44
 
  OPERATING STRATEGIES
 
     - Provide an exceptional living environment for residents. The Existing
       Communities on the Irvine Ranch have been developed and are maintained to
       appeal to the highly educated, relatively affluent base of renters
       attracted to the Irvine Ranch. As a result of the region's closely
       managed master-planning process, the Irvine Ranch Properties are situated
       amid parks and other open space, and in close proximity to employment
       centers, schools, retail centers, and recreational facilities. They
       provide generous amenities, are well maintained and offer a high standard
       of customer service. The Operating Partnership's success in providing an
       exceptional quality of life for its residents is evidenced in part by the
       strong average rental rates the Existing Communities on the Irvine Ranch
       command relative to average rental rates for Orange County as a whole. In
       1996, the stabilized Existing Communities on the Irvine Ranch produced an
       average monthly rent of $1,025 per unit, which was approximately $200
       more than the average monthly rent in Orange County.
 
     - Enhance efficiency of operations. Management of the Company selectively
       subcontracts on-site staffing, personnel management and accounting
       functions to three independent property management firms which enables it
       to focus on marketing, product pricing and positioning, and approval of
       operating budgets. Management additionally directs and tests the
       standards of property-level activities conducted by the firms, including
       training of on-site staff.
 
     - Capitalize on strong brand identity with enhanced marketing and
       merchandising programs. The Operating Partnership has enhanced certain of
       its marketing programs to broaden its already strong brand name
       recognition in order to attract new residents into its portfolio and
       broaden the existing resident base. The Operating Partnership's marketing
       programs include: a website and a single source 800 telephone number to
       provide information on the Properties; rental information centers within
       major shopping centers and the University of California at Irvine; and a
       targeted advertising campaign promoting the Operating Partnership's
       portfolio and its strong quality of life characteristics.
 
  DEVELOPMENT STRATEGIES
 
     - Develop new communities to complement and expand the Operating
       Partnership's existing rental market base. A diverse regional economy,
       continuing population growth, and an attractive quality of life all
       contribute to a broad and varied demand for rental housing on the Irvine
       Ranch. As a result, opportunities exist for a variety of apartment
       property types and amenity levels, including projects designed for the
       family, luxury and senior markets, and the area's large population of
       young professionals. The Operating Partnership's development program on
       the Irvine Ranch seeks to capitalize on these opportunities through
       market segmentation. Supported by consumer research and focus group
       studies, market segmentation decisions are made at the earliest planning
       stages, when new residential villages for the Irvine Ranch are conceived
       and the villages' largest and most important amenities are selected.
       Location of schools, recreational facilities, retail centers, open space
       and views are all important considerations. Individual development
       decisions -- including site location, product design, amenities and
       marketing programs -- are also geared to appeal to the needs and desires
       of the target rental market.
 
     - Utilize experienced management to create high-quality, well-built
       properties designed to sustain value. The Operating Partnership brings
       considerable management expertise to all aspects of the development,
       construction and leasing process. Senior management of the Company is
       actively involved in new project development from the inception of a new
       Irvine Ranch village and is responsible for target market identification;
       design of site plans, building plans, and floor plans; project and unit
       amenity selection; and site-specific governmental approvals. In addition,
       the Operating Partnership directs the bidding and contracting of all
       major construction activities, in essence acting as general contractor.
       The Operating Partnership engages experienced independent construction
       managers to act as intermediaries with subcontractors and to manage
       on-site activities under the close supervision of the Operating
       Partnership's internal construction group. The Operating Partnership
       builds properties using only high-quality construction materials and
       techniques, and believes that this higher initial investment in quality
       enhances long-term value creation by sustaining high community rental
       income levels and reducing long-term expense levels.

  "OFF-RANCH" EXPANSION
 
   
     While the Operating Partnership's principal focus has been on the
development of apartment communities on the Irvine Ranch, the Operating
Partnership has commenced an "off-Ranch" expansion program and will continue to
consider other opportunities to develop or acquire apartment communities in
California, that offer attractive risk-adjusted returns. The Operating
Partnership's intent is to create new market positions in the Silicon Valley and
Northern San Diego County and other locations in California which possess strong
rental demographics and economic growth prospects similar to those on the Irvine
Ranch. In addition, the three senior real estate executives at Thompson
Residential Company, Inc. ("TRC"), a privately held, Northern California-based
multifamily development company, have joined the Company with primary
responsibility for the Operating Partnership's "off-Ranch" California
operations. See Note 5 to the OP Unaudited Quarterly Financial Statements.
    
 
IRVINE RANCH MASTER PLAN
 
     The urbanization of the Irvine Ranch began in the 1960s with the adoption
of the pioneering comprehensive Master Plan for future community development
which originally constituted a large map of the Irvine Ranch and a series of
supporting maps detailing land uses. Subsequently, The Irvine Company worked
closely with the various local jurisdictions who govern the Irvine Ranch to
adopt general plans for the future development of their jurisdictions. The
Irvine Company's overall Master Plan was refined to accord with the approved
general plans and the residential, commercial, industrial, environmental and
aesthetic balance desired by each jurisdiction. As a result, today the Irvine
Ranch Master Plan is a compilation of the various interlocking general plans
described above. The Irvine Company continuously engages in planning activities
and the Master Plan refinement process is ongoing. The Irvine Company works
closely with local government representatives, community residents and other
civic and environmental groups to obtain the necessary local support and
entitlements for its developments. The goal of the Master Plan was and remains
to create innovative urban and suburban environments through the well-planned,
coordinated development of residential communities and employment centers (which
include major business and retail centers, and research and development and
industrial parks) as well as civic, cultural, recreational, educational and
other supportive facilities, all with an emphasis on improving the quality of
life and achieving long-term balanced regional economic growth.
 
     The success of the Irvine Ranch as a master-planned development is in the
large part attributable to the early creation of a broad employment base. The
Irvine Company has emphasized the promotion of job creation on the Irvine Ranch
and has been involved in creating four major employment centers on the Irvine
Ranch, each easily accessible by apartment residents and the surrounding area.
The Irvine Company has been the sole developer of the Irvine Spectrum, a
3,600-acre research, technology and employment center which houses more than
2,200 companies and approximately 44,000 employees and includes more than 2.0
million square feet of office and other commercial space and over 15.5 million
square feet of industrial space. The Irvine Business Complex, which surrounds
the John Wayne airport, houses over 100,000 employees and includes more than 24
million square feet of office and other commercial space and over 14 million
square feet of industrial space. Newport Center contains over 4.4 million square
feet of office space, a 1.3 million square-foot regional mall (Fashion Island),
a tennis club and two country clubs. In addition, The Irvine Company donated
land to the University of California at Irvine, a 1,489-acre campus which
currently has more than 16,000 students and 5,500 employees. The proximity of
the Irvine Ranch Properties to these employment centers makes them attractive
residential locations.
 
  MARKET SEGMENTATION AND THE VILLAGE CONCEPT
 
     The Irvine Company's land use planning emphasizes market segmentation in
order to ensure adequate and appropriate allocation of land uses which support
sustained growth for the long term. Through careful planning, design and
marketing, The Irvine Company also promotes compatibility and synergy among
properties of the same type in order to maximize the likelihood of success of
new projects, to preserve and build value for existing projects and to build
sustainable long-term market value for homeowners, local
 
                                       44
<PAGE>   46
 
merchants and employers. In accordance with the Master Plan, The Irvine Company
has created twelve villages which are used as micro-planning areas in an effort
to facilitate the desired segmentation of products.
 
     Each village across the Irvine Ranch has a thematic identity which
characterizes the primary features and attributes of the village and helps to
identify the target market for the Operating Partnership's product. For example,
Tustin Ranch, in the City of Tustin, is a family-oriented village featuring an
18-hole championship golf course, athletic fields, jogging, hiking and
equestrian trails. Along the ocean is the village of Newport Coast, an upscale
community featuring ocean views and million-dollar custom built homes. The
village of Westpark, in Irvine, caters to young professionals with growing
families and offers the highly renowned public school system and recreational
facilities of the City of Irvine.
 
     Within each village, the Operating Partnership's target market is further
defined. The primary factor which determines the appropriate target for the
Operating Partnership's product is location. For example, the conventional
product which is targeted towards young professionals is typically located near
major business centers and in close proximity to entertainment, retail
establishments and major transportation corridors. The student product, on the
other hand, is located within walking distance of a college or university,
student-oriented retail centers, and public transportation.
 
     Finally, the Operating Partnership specifically designs its products to
appeal to a target market. The Operating Partnership's luxury product is
typically in a unique location with ocean or golf course views. The family
products offer spacious play areas and tot lots, a children's multi-purpose room
with an activities coordinator, individual garages and in-unit washers and
dryers.
 
EXCLUSIVE LAND RIGHTS AGREEMENT
 
   
     The Company, the Operating Partnership and The Irvine Company are parties
to the Land Rights Agreement pursuant to which, through July 31, 2020, the
Company and the Operating Partnership have the exclusive right, but not the
obligation, to acquire all land sites entitled for residential use and
designated by The Irvine Company as ready for apartment community development in
accordance with The Irvine Company's Master Plan. The determination to exercise
an option with respect to a site is made solely by the Independent Directors
Committee of the Company's Board of Directors. Under this Agreement, the
Operating Partnership has purchased ten apartment community land sites since the
Company's Initial Public Offering, seven of which are now Existing Communities
and three of which are now the Communities Under Construction. Under the terms
of the Land Rights Agreement, through July 31, 2000, the purchase price for any
apartment community sites acquired may be paid with either cash, Common Stock of
the Company or Common L.P. Units, at the option of the Company. After July 31,
2000, the choice of consideration will revert to The Irvine Company. In no event
shall the purchase price for any apartment community land site exceed 95% of the
value of such site as determined by independent appraisals. In addition, the
purchase price for apartment sites which encompassed the first 1,800 apartment
units the Operating Partnership developed commencing in mid-1995 were set at an
amount such that each project's budgeted pro forma unleveraged return on costs
for the first 12 months following stabilized occupancy was between 10.0% and
10.5%. Seven land sites for the development of apartment communities which will
contain 1,884 units have been purchased under this arrangement. See "Certain
Relationships and Related Transactions -- Transactions with The Irvine Company."
Accordingly, as of the date of this Prospectus the purchase price for all future
land sites will be no greater than 95% of the appraised value. Independent
appraisals will be obtained by each of the Operating Partnership and The Irvine
Company for all future sites, prior to the Independent Directors Committee
determining whether the Operating Partnership will exercise its right to
purchase a land site. If the Operating Partnership elects not to exercise its
option for any site, the Operating Partnership will thereafter have a right of
first refusal on the sale of such site to a third party if the terms of such
sale are more favorable than those offered to the Operating Partnership. The
determination to exercise an option or the right of first refusal under the Land
Rights Agreement with respect to any site will be made solely by a majority of
the Independent Directors Committee.
    
 
     Pursuant to the Land Rights Agreement, The Irvine Company and Mr. Bren have
agreed to conduct their apartment community development and ownership activities
on the Irvine Ranch solely through the Company
 
                                       45

and the Operating Partnership. These restrictions terminate upon the occurrence
of certain conditions. See "Risk Factors -- Early Termination of the Exclusive
Land Rights and Non-Competition Arrangements with The Irvine Company and Mr.
Bren Would Adversely Affect the Operating Partnership."
    
 
THE PROPERTIES
 
     As of September 30, 1997, the Operating Partnership owned and operated
14,991 apartment units in the Existing Communities and had four Communities
Under Construction. The Operating Partnership believes that the Properties are
high quality apartment communities with superior locations near major employment
centers and, in the case of Irvine Ranch Properties, within master-planned
villages. The Properties are located within the following individual
jurisdictions:

(1) Four of these Properties (aggregating 1,110 units) are Communities Under
    Construction.
 
  EXISTING COMMUNITIES
 
     The Existing Communities consist of 51 apartment communities of two, three
or four stories, containing 14,991 units. The Company believes that the Existing
Communities are well maintained and have no material deferred maintenance
requirements. The average age of the Existing Communities is approximately 11
years. The oldest of the Existing Communities was completed in 1969, and 32 of
the 51 Existing Communities, totaling 10,323 units or approximately 68.9% of the
units in the Existing Communities, have been completed since January 1, 1985.
The number of units per apartment community ranges from 58 units to 923 units,
with an average of approximately 294 units. Approximately 88% of the units are
one- or two-bedroom apartments. The apartment units average 946 square feet.
 
     Excluding The Villas of Renaissance, 43 of the Existing Communities,
representing 11,334 units, achieved stabilized occupancy prior to January 1,
1996, and for the nine months ended September 30, 1997, these Existing
Communities had an average physical occupancy rate of 94.5% and an average
monthly rent per unit of $1,068. Five Existing Communities, containing 2,207
units, were in lease-up throughout 1995 and achieved stabilized occupancy during
1996. For the nine months ended September 30, 1997 these five Existing
Communities had an average physical occupancy of 94.5%. The Operating
Partnership also acquired The Villas of Renaissance (containing 923 units) on
June 30, 1997. See "Recent Developments -- 'Off-Ranch' Expansion." The two
remaining Existing Communities containing 527 units achieved stabilized (95%)
occupancy in July 1997.
 
     All of the Existing Communities offer apartment residents numerous
amenities and include extensive landscaping. Approximately 80% of the 51
Existing Communities contain a swimming pool, spa, air conditioning and covered
parking. Additional amenities may include a fitness center, recreational room,
sauna and tennis courts. Each apartment unit includes a patio, entry porch or
balcony. Many apartment units offer one or more of certain additional features,
such as vaulted ceilings, fireplaces, enclosed garages, refrigerators, washers
and dryers and microwave ovens.

     The Operating Partnership seeks to assure that the Properties remain
attractive dwellings for apartment residents and desired locations for
prospective apartment residents. Local property manager maintenance, custodial
and grounds keeping personnel perform regular maintenance and upkeep on the
Properties to preserve the enhanced physical and aesthetic attributes. The
physical appearance of, and apartment residents' satisfaction with, the
Properties and with the performance of the local property managers is monitored
and evaluated on an ongoing basis by senior management. The following table sets
forth certain information as of December 31, 1996 regarding the 48 Existing
Communities which had achieved stabilized occupancy:

    Operating Partnership on June 30, 1997. See "Recent
    Developments -- 'Off-Ranch' Expansion."
 
  COMMUNITIES IN LEASE-UP AND COMMUNITIES UNDER CONSTRUCTION
 
     The Operating Partnership had no communities in lease-up at September 30,
1997. Two Existing Communities (Baypointe and Santa Maria) began deliveries of
units in the fourth quarter of 1996, with the final units being delivered in
June 1997. Each such Property had achieved stabilized occupancy by July 20,
1997. The Operating Partnership had four Communities Under Construction (The
Colony, Santa Rosa II and Rancho Santa Fe on the Irvine Ranch; and The Hamptons
at Cupertino in Cupertino, California) at September 30, 1997, which will
comprise a total of 1,110 units upon completion. No units in the Communities
under Construction were ready for occupancy at September 30, 1997. The
Communities Under Construction will include amenities substantially similar to
those in the Existing Communities.
 
MANAGEMENT AND CONTROL OF THE OPERATING PARTNERSHIP
 
     As sole general partner of the Operating Partnership, the Company has the
exclusive power to manage and conduct the business of the Operating Partnership.
The Company, in turn, is governed by a Board of Directors, which has a majority
of directors unaffiliated with The Irvine Company. Furthermore, the Board of
Directors of the Company has established the Independent Directors Committee,
whose approval is required with respect to all transactions involving the
Operating Partnership and The Irvine Company, affiliates of The
 
                                       48
<PAGE>   50
 
Irvine Company or Mr. Bren, such as the acquisition of additional apartment
communities or sites therefor from The Irvine Company.
 
   
     In certain circumstances, consent of The Irvine Company is required by the
Partnership Agreement. Such consent is required, among other things, (i) to sell
all or substantially all of the assets of the Operating Partnership, (ii) for
the Company to take title to assets (other than temporarily in connection with
an acquisition prior to contributing such assets to the Operating Partnership)
or for the Company to conduct business other than through the Operating
Partnership, (iii) for the Operating Partnership to engage in any business other
than the development and ownership of apartment communities or (iv) in
connection with the liquidation, dissolution, winding-up or termination of the
Operating Partnership. The Partnership Agreement requires, absent receipt of
consent, that title to assets be in the Operating Partnership in order to
maintain a one-for-one exchange ratio between Common L.P. Units and shares of
Common Stock of the Company. See "Operating Partnership
Agreement -- Management."
    
 
   
     At the option of The Irvine Company, The Irvine Company's limited
partnership interest in the Operating Partnership is exchangeable for Common
Stock of the Company pursuant to the Exchange Rights (subject to the ownership
limit applicable to The Irvine Company and certain related persons) contained in
the Company's Articles of Incorporation or pursuant to the Cash Tender Rights
may be tendered to the Company for cash payable solely out of the net proceeds
of an offering of Common Stock of the Company.
    
 
COMPETITION
 
     The Properties are located in developed areas. There are numerous other
rental apartment properties within and around the market area of each Property.
The number of competitive rental properties in the area could have a material
effect on the Operating Partnership's ability to rent the apartments at the
Properties and the rents charged.
 
EMPLOYEES
 
     As of September 30, 1997, the Company had 66 employees. None of such
employees is subject to a collective bargaining agreement and the Operating
Partnership has experienced no labor-related work stoppages. The Operating
Partnership considers its relations with its personnel to be good.
 
CYCLICALITY
 
     The Operating Partnership's business, and the residential housing industry
in general, are cyclical. The Operating Partnership's operations and markets are
affected by local and regional factors such as local economies, demographic
demand for housing, population growth, property taxes, energy costs, and by
national factors such as short and long-term interest rates, federal mortgage
financing programs, federal income tax provisions and general economic trends.
Occupancy varies only slightly on a seasonal basis, with the lowest occupancy
typically occurring in the summer months.
 
ENVIRONMENTAL MATTERS
 
     Under various federal, state and local laws, ordinances and regulations, an
owner of real property may be held liable for the costs of removal or
remediation of certain hazardous or toxic substances located on or in the
property. These laws often impose such liability without regard to whether the
owner knew of, or was responsible for, the presence of the hazardous or toxic
substances. The costs of any required remediation or removal of such substances
may be substantial. In addition, the owner's liability as to any property is
generally not limited under such laws, ordinances and regulations and could
exceed the value of the property and/or the aggregate assets of the owner. The
presence of such substances, or the failure to remediate such substances
properly, may also adversely affect the owner's ability to sell or rent the
property or to borrow using the property as collateral. Under such laws,
ordinances and regulations, an owner or any entity who arranges for the disposal
of hazardous or toxic substances, such as asbestos, at a disposal facility may
also be liable for the costs of any required remediation or removal of the
hazardous or toxic substances at the facility, whether or not the facility is
owned or operated by such owner or entity. In connection with the ownership of
the
 
                                       49
<PAGE>   51
 
Properties or the disposal of hazardous or toxic substances, the Operating
Partnership may be liable for such costs.
 
     The groundwater underlying portions of the City of Irvine generally
contains elevated levels of certain inorganic compounds. In addition, two United
States Marine Corps air bases where soil and groundwater contamination have been
discovered are located adjacent to the Irvine Ranch. Although the Operating
Partnership believes that contamination at one of these bases is localized,
there can be no assurances that it has not migrated onto any of the Properties.
The other base is listed on the National Priorities List and activities from
this base have resulted in groundwater contamination in the vicinity of this
base. The Operating Partnership has knowledge that contamination from this base
has migrated into the groundwater underlying some of the Properties. The
Operating Partnership believes that most of the groundwater is located at a
substantial depth under the land surface. Since the Operating Partnership
believes that the Orange County Water District together with the Department of
Defense are currently conducting and will continue to conduct remediation
activities at this base and in the area, the Operating Partnership believes that
it will not incur any remediation costs in connection with the groundwater
contamination.
 
     Other federal, state and local laws may impose liability for release of
asbestos containing materials ("ACMs") into the air or require the removal of
damaged ACMs in the event of remodeling or renovation. There are ACMs at 11 of
the Properties, primarily in floor coverings and acoustical ceiling materials.
The Operating Partnership believes that the ACMs at these properties are
generally in good condition. Comprehensive operations and maintenance plans have
been implemented for properties where ACMs are present. In addition, property
custodial and maintenance workers are trained to deal effectively with the
maintenance of existing ACMs. The Operating Partnership believes it is in
compliance in all material respects with all federal, state, and local laws
relating to ACMs and that there are no regulatory requirements that currently
require the removal of these ACMs; however, if the Operating Partnership were
required to remove all ACMs present in its properties over a short time frame,
the cost of such removal would have a material adverse effect on its financial
condition and results of operations. The Operating Partnership also believes
that ACMs are not present in the remaining Properties. The Irvine Ranch Water
District, a municipal corporation, owns and maintains underground cement water
pipes which contain asbestos and which are serving a number of the Properties.
Since these pipes are owned and maintained by the Irvine Ranch Water District,
the Operating Partnership believes that any potential environmental liabilities
associated with these pipes will be incurred by the Irvine Ranch Water District.
 
     The Operating Partnership has not been notified by any governmental
authority of any material noncompliance, liability, or other claim in connection
with any of the Properties. In addition, environmental assessments (which
involve physical inspections without soil or groundwater analyses and generally
without radon testing) were obtained on all 48 Existing Communities in 1993 or
later except for two which were obtained more than five years ago. Environmental
assessments were performed on all sites under construction prior to their
purchase. The Operating Partnership is not aware of any environmental liability
relating to the Properties that it believes would have a material adverse effect
on its business, assets or results of operations. Nevertheless, it is possible
that the environmental assessments did not reveal all environmental liabilities
with respect to the Properties, that environmental liabilities have developed
with respect to the Properties since the environmental assessments were prepared
or that there are material environmental liabilities of which the Operating
Partnership is unaware with respect to the Properties. Moreover, no assurance
can be given that future laws, ordinances or regulations will not impose
material environmental liabilities or that the current environmental condition
of the Properties will not be affected by residents and occupants of the
Properties or by the uses or condition of properties in the vicinity of the
Properties, such as leaking underground storage tanks, or by third parties
unrelated to the Operating Partnership.
 
REGULATION
 
     Apartment community properties are subject to various laws, ordinances, and
regulations, including regulations relating to recreational facilities such as
swimming pools, activity centers and other common areas. The Operating
Partnership believes that each Property has all material permits and approvals
to operate its
 
                                       50
<PAGE>   52
 
business. Rent control laws currently are not applicable to any of the
Properties. However, there can be no assurance that rent control requirements
will not be initiated in the future.
 
     The Properties and any newly acquired or developed apartment communities
must comply with Title II of the Americans with Disabilities Act (the "ADA") to
the extent that such properties are "public accommodations" and/or "commercial
facilities" as defined by the ADA. Compliance with the ADA requires removal of
structural barriers to handicapped access in certain public areas of the
Properties where such removal is "readily achievable." The ADA does not,
however, consider residential properties, such as apartment communities, to be
public accommodations or commercial facilities, except to the extent portions of
such facilities, such as a leasing office, are open to the public. The Operating
Partnership believes that the Properties comply in all material respects with
all present requirements under the ADA and applicable state laws. Noncompliance
with the ADA could result in imposition of fines or an award of damages to
private litigants.
 
     The Fair Housing Act ("FHA") requires, as part of the Fair Housing
Amendments Act of 1988, apartment communities first occupied after March 13,
1990 to be accessible to the handicapped. Noncompliance with the FHA could
result in the imposition of fines or an award of damages to private litigants.
The Operating Partnership believes that the Properties that are subject to the
FHA are in compliance with such law.
 
     Approximately 2,900 units in portions of 31 of the Operating Partnership's
Existing Communities are currently subject to resident income limitations which
generally restrict rental of the affected units to low or moderate income
residents and which, in most instances, also limit the amount of rent that may
be charged for a particular unit. A brief summary of the basis and effect of
these resident income and other limitations follows:
 
     The development of 23 of the 31 Existing Communities was financed with the
proceeds of tax-exempt multifamily housing revenue bonds issued by various local
municipalities. These bonds were refunded in May 1995 and consolidated under one
issuer, California Statewide Communities Development Authority. Regulatory
agreements applicable to such financings (a) require that a specified percentage
of the units be set aside for residents whose incomes do not exceed a specified
percentage of the area median income and (b) in most instances, limit the rent
which can be charged to a percentage of the maximum qualifying resident income
level for the affected unit. Most of these restrictions will terminate upon the
maturity date of the bond issue.
 
     In addition to the rental restrictions imposed by the bond regulatory
agreements, many of the 23 properties and three additional properties are also
subject to resident income and rent limitations by virtue of development and
other agreements entered into with local municipalities and private and
quasi-public interest groups. These restrictions are similar in scope and
substance to the other restrictions discussed above.
 
     Five of the 31 Existing Communities were developed with the assistance of
U.S. Department of Housing and Urban Development ("HUD") administered programs
which provided mortgage insurance to the project lender. Certain regulatory and
other agreements with HUD applicable to such financings (a) impose resident
income restrictions similar to those imposed by the bond financing agreements,
and (b) generally require the Operating Partnership to operate the Properties in
accordance with HUD's standards. With respect to one of the properties (i.e.,
The Parklands), a regulatory agreement additionally (a) limits the distribution
of income from the property to 10% of the HUD imputed equity in the property and
(b) requires that any income in excess of such 10% limit be deposited into a
residual receipts account. Amounts paid into such residual receipts account have
historically been used for capital improvements to the property, subject to
HUD's consent. At the expiration of the applicable regulatory or other
agreement, any amount remaining in such residual receipts account belongs to
HUD.
 
     Under Section 8 of the United States Housing Act of 1937, HUD currently
provides rental assistance payments to each of these five HUD properties
pursuant to certain Housing Assistance Payments ("HAP") contracts. Under the HAP
contracts, so long as the units are rented to residents whose income levels do
not exceed specified HUD guidelines, each qualifying resident is required to pay
only 30% of their adjusted monthly income as rent and HUD pays the difference
between the 30% payment and the unit's market rents
 
                                       51
<PAGE>   53
 
as established by HUD. The above-mentioned restrictions and limitations will
continue for the remainder of each HAP contract term, each HAP contract has an
initial term of 20 years with four 5-year renewal options exercisable at the
owners option. At September 30, 1997 the average remaining term of the HAP
contracts was approximately 6 years.
 
     Each of the resident and income restricted units within the Operating
Partnership's portfolio has been subject to one or more of the foregoing
restrictions either since their initial occupancy or as a result of subsequent
agreements with the applicable governmental authority or other private or
quasi-public interest groups. Accordingly, the effect of these restrictions on
rental income from the Properties has been reflected in the historical financial
results of the Operating Partnership and its Predecessor.
 
     The Operating Partnership believes that it is in material compliance with
all of the foregoing requirements. The failure of the Operating Partnership to
comply with the terms of any of the foregoing could adversely affect the
Operating Partnership's operations.
 
     The Operating Partnership may purchase land in the future which as a
condition of purchase has the inclusion of units at below market rental rates.
Construction of such properties may be financed with tax-exempt debt. In any
case, the Operating Partnership will evaluate the economics inclusive of any
rental restriction and benefit of below-market, tax-exempt financing prior to
purchasing the land.
 
FACTORS RELATING TO REAL ESTATE OPERATIONS AND DEVELOPMENT
 
     General. Real property investments are subject to varying degrees of risk.
The investment returns available from equity investments in real estate depend
in large part on the amount of income earned and capital appreciation generated
by the related properties as well as the expenses incurred. If the Properties do
not generate revenue sufficient to meet operating expenses, including debt
service and capital expenditures, the Operating Partnership's income and ability
to service its debt and other obligations and to make distributions on its
partnership interests, including the Series A Preferred L.P. Units, will be
adversely affected. In addition, the Properties consist primarily of apartment
communities located in Orange County. Income from and the performance of the
Irvine Ranch Properties may therefore be adversely affected by the general
economic climate in Orange County, including unemployment rates and local
conditions such as the supply of and demand for apartments in the area, the
attractiveness of the Irvine Ranch Properties to residents, zoning or other
regulatory restrictions, competition from other available apartments and
alternative forms of housing, the affordability of single family homes, the
ability of the Operating Partnership to provide adequate maintenance and
insurance and the potential of increased operating costs (including real estate
taxes). Certain significant expenditures associated with an investment in real
estate (such as mortgage and other debt payments, real estate taxes and
maintenance costs) generally are not reduced when circumstances cause a
reduction in revenue from the investment. In addition, income from properties
and real estate values are also affected by a variety of other factors, such as
governmental regulations and applicable laws (including real estate, zoning and
tax laws), interest rate levels and the availability of financing. The Irvine
Ranch Properties in the aggregate historically have generated positive cash flow
from operations; however, no assurance can be given that such will be the case
in the future.
 
     In 1997, the Operating Partnership commenced an "off-Ranch" expansion
program through the acquisition of rights to purchase three apartment community
development sites located in Northern California's Silicon Valley. The Operating
Partnership commenced construction of a 342-unit apartment community on one of
such sites in May 1997 and on October 23, 1997, the Company's Board of Directors
authorized, subject to receipt of necessary entitlements, the acquisition of
another of the development sites. Construction of an apartment community of
approximately 155 units on this site is expected to commence in the first half
of 1998. On June 30, 1997, the Operating Partnership acquired an existing
923-unit apartment community located in Northern San Diego County. These new
Properties represent the Operating Partnership's first strategic expansion off
the Irvine Ranch and the Operating Partnership may make additional investments
in California in the future. The development, construction and operation of
rental apartment communities in such new markets may present risks different
than or in addition to the risks discussed above related to the Irvine Ranch
Properties which are located entirely in Orange County. In addition, in contrast
to
 
                                       52
<PAGE>   54
 
acquisitions of land pursuant to the Land Rights Agreement in which a
substantial portion of pre-development costs and expenses, including the cost
and expense of obtaining Village Related Entitlements, is borne solely by The
Irvine Company, all pre-development costs and expenses in connection with
"off-Ranch" expansion will be borne by the Operating Partnership and the
Operating Partnership will bear all risk relating to the failure to obtain
entitlements. For jurisdictions off the Irvine Ranch, local jurisdiction
approvals with respect to entitlements may impose requirements and conditions
different from those applicable to the Irvine Ranch. No assurance can be given
that the Operating Partnership will be successful in pursuing any additional
"off-Ranch" expansion or that any "off-Ranch" apartment communities will be
successful.
 
     Equity real estate investments, such as the investments made by the
Operating Partnership in the Properties and any additional properties that may
be developed or acquired by the Operating Partnership, are relatively illiquid.
Such illiquidity limits the ability of the Operating Partnership to vary its
portfolio in response to changes in economic or other conditions.
 
     The Properties are subject to all operating risks common to apartment
ownership in general. Such risks include: the Operating Partnership's ability to
rent units at the Properties, including the 1,110 units in the Communities Under
Construction; competition from other apartment communities; excessive building
of comparable properties which might adversely affect apartment occupancy or
rental rates; increases in operating costs due to inflation and other factors,
which increases may not necessarily be offset by increased rents; increased
affordable housing requirements that might adversely affect rental rates;
inability or unwillingness of residents to pay rent increases; and future
enactment of rent control laws or other laws regulating apartment housing,
including present and possible future laws relating to access by disabled
persons. If operating expenses increase, the local rental market may limit the
extent to which rents may be increased to meet increased expenses without
decreasing occupancy rates. If any of the above occurred, the Operating
Partnership's ability to meet its debt service and other obligations and to make
distributions on its partnership interests, including with respect to the Series
A Preferred L.P. Units, could be adversely affected.
 
     Real Estate Development and Acquisition. A primary focus of the Operating
Partnership is on the development of new apartment communities on sites acquired
or that may be acquired in the future primarily from The Irvine Company,
although the Operating Partnership also plans to develop new rental apartment
communities on sites acquired or that may be acquired in the future from third
parties. The Operating Partnership has also acquired, and may continue to
acquire, completed communities. See "Recent Developments -- 'Off-Ranch'
Expansion." The real estate development business involves significant risks in
addition to those involved in the ownership and operation of established
apartment communities, including the risks that specific project approvals may
take more time and resources to obtain than expected, that construction may not
be completed on schedule or budget and the properties may not achieve
anticipated rent or occupancy levels. In addition, if long-term debt or equity
financing is not available on acceptable terms to finance new development or
acquisitions undertaken without long-term financing, further development
activities or acquisitions might be curtailed or cash available for debt service
and other obligations might be adversely affected.
 
     Insurance. The Operating Partnership carries comprehensive liability, fire,
extended coverage and rental loss insurance covering all of the Properties, with
policy specifications and insured limits which the Operating Partnership
believes are adequate and appropriate under the circumstances. There are,
however, certain types of losses (such as from earthquakes) that are not
generally insured because they are either uninsurable or not economically
insurable. The Operating Partnership does not carry earthquake insurance on any
of the Properties. Should an uninsured loss or a loss in excess of insured
limits occur, the Operating Partnership could lose its capital invested in the
Property, as well as the anticipated future revenues from the Property, and, in
the case of debt which is recourse to the Operating Partnership, would remain
obligated for any mortgage debt or other financial obligations related to the
Property. Any such loss would adversely affect the Operating Partnership. The
Operating Partnership believes that the Properties are adequately insured. In
addition, in light of the California earthquake risk, California building codes
since the early 1970s have established construction standards for all newly
built and renovated buildings, including apartment buildings, the current and
strictest construction standards having been adopted in 1984. Thirty-two of the
51 Existing Communities (representing approximately 68.9% of the units in the
Existing Communities) have been
 
                                       53
<PAGE>   55
 
completed and occupied since January 1, 1985 and the Operating Partnership
believes that all of the Existing Communities were constructed, and all of the
Communities Under Construction are being constructed, in full compliance with
the applicable standards existing at the time of construction. While earthquakes
have occurred from time to time in California, the Operating Partnership has not
experienced any material losses as a result of earthquakes. No assurance can be
given that this will be the case in the future.
 
LEGAL PROCEEDINGS
 
     None of the Operating Partnership, the Trust or the Company is currently
subject to any material litigation.

                  POLICIES WITH RESPECT TO CERTAIN ACTIVITIES
 
OPERATING PARTNERSHIP
 
     The following is a discussion of investment policies, financing policies,
conflict of interest policies and policies with respect to certain other
activities of the Operating Partnership. The policies with respect to these
activities have been determined by the Board of Directors of the Company, as
general partner of the Operating Partnership, and may be amended or revised from
time to time at the discretion of the Board of Directors, except that (i) the
approval of the Required Directors as provided in the Articles of Incorporation
and the consent of a majority of the holders of Common L.P. Units as provided in
the Partnership Agreement are required for the Company to take title to assets
(other than temporarily in connection with an acquisition prior to contributing
such assets to the Operating Partnership) or to conduct business other than
through the Operating Partnership, or for the Company or the Operating
Partnership to engage in any business other than the ownership, construction,
development and operation of apartment communities, (ii) changes in certain
policies with respect to conflicts of interest must be consistent with legal
requirements, and (iii) the policies with respect to competition by The Irvine
Company and Mr. Bren are imposed pursuant to a contract that cannot be amended
or waived without the vote of the Independent Directors Committee.
 
  INVESTMENT POLICIES
 
     Investments in Real Estate or Interests in Real Estate. The Operating
Partnership's business is focused solely on the ownership, construction,
development and operation of rental apartment communities and the Company
conducts all of its investment activities through the Operating Partnership. The
Operating Partnership's investment objective is to provide stable cash flow
available for quarterly cash distributions and achieve long-term appreciation
through increases in cash flows and the value of its Properties. The Operating
Partnership intends to pursue these objectives by (i) investing capital to
enhance investment returns on the Properties, (ii) developing rental apartment
communities on the Irvine Ranch for long-term ownership and (iii) developing or
purchasing rental apartment communities off the Irvine Ranch where the Operating
Partnership believes that opportunities exist for attractive investment returns.
The Operating Partnership may expand or improve existing properties or, subject
to the approval of the Required Directors, sell such properties in whole or in
part as determined by the Company's Board of Directors. See "Business and
Properties of the Operating Partnership -- Business Strategy -- Development
Strategies."
 
     The Operating Partnership expects to pursue its investment objective
through the direct ownership of the Properties and future developed properties
and the ownership of interests in special purpose partnerships. Future
development or investment activities will not be limited to any specified
percentage of the Operating Partnership's assets.
 
     Investments in Others. The Operating Partnership may also participate with
other entities in property ownership, through joint ventures or other types of
co-ownership. Equity investment may be subject to existing mortgage financing
and other indebtedness which have priority over the equity of the Operating
Partnership.
 
     Investments in Real Estate Mortgages. While the Operating Partnership will
emphasize equity real estate investments, it may, in its discretion and subject
to the percentage ownership limitations and gross income tests necessary for the
Company's REIT qualification, invest in mortgage and other real estate interests
including securities of other real estate investment trusts. The Operating
Partnership has not previously invested in mortgages or securities of other real
estate investment trusts and the Operating Partnership does not presently intend
to invest to a significant extent in mortgages or securities of other real
estate investment trusts.
 
  FINANCING POLICIES
 
     The Company, as general partner of the Operating Partnership, currently
intends to maintain a conservative ratio of debt to total market capitalization
(i.e., the market value of issued and outstanding shares of Common Stock and
L.P. Units plus total debt) and in any event not greater than 60%. The Company's
ratio of debt to total market capitalization was 31.2% at September 30, 1997 and
28.0% on a pro forma basis after
 
                                       55
<PAGE>   57
 
giving effect to the issuance of the 7% Notes and the Series A Preferred L.P.
Units in connection with the Offering (assuming no exercise of the Underwriters'
overallotment option). The Company, however may from time to time reevaluate
borrowing policies in light of then current economic conditions, relative costs
of debt and equity capital, market values of properties, growth and acquisition
opportunities and other factors.
 
     The Company, as general partner of the Operating Partnership, has
established a debt policy relative to its market capitalization, a ratio
commonly employed by REITs, rather than to the book value of its assets, because
the Company believes that the book value of its assets (which to a large extent
is the depreciated value of its apartment communities) does not accurately
reflect its ability to borrow and to meet debt service requirements. The market
capitalization of the Company, however, is more variable than book value and
does not necessarily reflect the fair market value of the underlying assets of
the Operating Partnership. Although the Company, as general partner of the
Operating Partnership, will consider factors other than market capitalization in
making decisions regarding the incurrence of debt and the issuance of Preferred
L.P. Units by the Operating Partnership (such as the estimated market value of
such properties upon refinancing, and the ability of particular properties and
the Company as a whole to generate cash flow to cover expected debt services),
there can be no assurance that the Company will maintain the ratio of debt to
market capitalization (or to any other measure of asset value) described above.
 
     To the extent that the Board of Directors of the Company determines to seek
additional capital, the Company may raise such capital through additional equity
offerings, including the issuance of additional series of Preferred L.P. Units
to the Trust or otherwise, debt refinancing or retention of cash flow by the
Operating Partnership (after consideration of provisions of the Code requiring
the distribution by a REIT of a certain percentage of taxable income and taking
into account taxes that would be imposed on undistributed taxable income), or
through a combination of these sources. The Company presently anticipates that
any additional borrowings will be made through the Operating Partnership. See
"Operating Partnership Agreement." The Operating Partnership cannot incur
indebtedness that is recourse to the Company without the Company's approval.
While the Company may approve the Operating Partnership incurring additional
debt that is recourse to the Operating Partnership, the Company does not
presently intend to approve the Operating Partnership incurring additional debt
that would be recourse to the Company other than with respect to general working
capital lines of credit and general construction financing credit facilities.
Borrowings may be unsecured or may be secured by any or all assets of the
Company, the Operating Partnership, or any existing or new property and may have
full or limited recourse to all or any portion of the assets of the Company, the
Operating Partnership, or any existing or new property.
 
     The Company, as general partner of the Operating Partnership, has not
established any limit on the number or amount of mortgages that may be placed on
any single Property or on the Operating Partnership's portfolio as a whole.
 
     The Operating Partnership has entered into the $250 million Credit
Facility, which is available to fund development activities, property
acquisitions and for general corporate purposes. The Company or the Operating
Partnership may also determine to issue securities including common stock,
preferred stock, L.P. Units and debt securities (any of which may be convertible
into capital stock or be accompanied by warrants to purchase capital stock). The
Company or the Operating Partnership may in the future finance acquisitions
through the exchange of properties or issuance of additional L.P. Units, shares
of Common Stock or other securities.
 
   
     In the event that the Company determines to raise additional equity
capital, such capital can be raised by either the Company or the Operating
Partnership. The Board of Directors of the Company has the authority, without
shareholder approval, to issue additional shares of Common Stock or other
capital stock of the Company in any manner (and on such terms and for such
consideration) it deems appropriate, including in exchange for property. In the
event that the Company issues (whether for cash or property) any Common Stock or
securities convertible into, or exchangeable or exercisable for, Common Stock,
The Irvine Company, subject to certain limited exceptions, including the
issuance of Common Stock pursuant to any stock incentive plan adopted by the
Company or pursuant to an exercise of the Exchange Rights or the Cash Tender
Rights, will have the right to purchase Common Stock or Common L.P. Units
exchangeable for Common Stock, or
    
 
                                       56
<PAGE>   58
 
such securities in order to maintain its percentage interest in the Company and
the Operating Partnership on a consolidated basis. However, shareholders of the
Company and holders of Preferred L.P. Units would have no such right. If the
Company's Board of Directors determines to raise additional equity capital to
fund investments by the Operating Partnership, the Company will contribute such
funds to the Operating Partnership as a contribution to capital and purchase an
additional general partnership interest; however, holders of Common L.P. Units
but not Preferred L.P. Units will have the right to participate in such funding
on a pro rata basis. In the event that holders of Common L.P. Units sell their
Common L.P. Units to the Company pursuant to their Cash Tender Rights, the
Company is authorized to raise the funds for such purchase by issuing additional
shares of Common Stock. In addition, the Company may issue additional shares of
Common Stock in connection with the exchange of Common L.P. Units for shares of
Common Stock pursuant to the exercise of Exchange Rights. See "Operating
Partnership Agreement."
 
     The Company's Board of Directors also has the authority, without approval
of the holders of L.P. Units, to cause the Operating Partnership to issue
additional Common L.P. Units and additional series of Preferred L.P. Units
(including to the Trust) in any manner (and on such terms and for such
consideration) as it deems appropriate, including in exchange for property. In
the event that the Operating Partnership issues new Common or Preferred L.P.
Units or securities of the Operating Partnership convertible into, or
exchangeable or exercisable for, L.P. Units to any person other than The Irvine
Company for cash (but not property), The Irvine Company will have the right to
purchase such L.P. Units in order, and to the extent necessary, to maintain its
percentage ownership interest in the Operating Partnership. Any such new Common
L.P. Units will be exchangeable for Common Stock pursuant to the Exchange Rights
or may be tendered to the Company pursuant to the Cash Tender Rights. See
"Operating Partnership Agreement -- Issuance of Additional L.P. Units."
 
  DISPOSITION POLICY
 
     The Operating Partnership believes that its concentration of Properties and
strong market position are a substantial competitive advantage. As such, the
Operating Partnership has no current intention to dispose of any of the
Properties, although it reserves the right to do so.
 
  CONFLICT OF INTEREST POLICIES
 
     The Company has adopted certain policies and entered into certain
agreements with The Irvine Company and Mr. Bren designed to eliminate or
minimize potential conflicts of interest. However, there can be no assurance
that these policies always will be successful in eliminating the influence of
such conflicts, and if they are not successful, decisions could be made that
might fail to reflect fully the interests of all shareholders of the Company and
holders of Preferred L.P. Units. The Board of Directors of the Company has
adopted a policy and has provided in its Bylaws that no transaction between the
Company or the Operating Partnership on the one hand and The Irvine Company,
affiliates of The Irvine Company or Mr. Bren on the other hand may be entered
into without the approval of the Independent Directors Committee.
 
   
     Exclusive Land Rights. The Irvine Company, the Company and the Operating
Partnership have entered into the Land Rights Agreement pursuant to which
through July 2020 the Company and the Operating Partnership hold the exclusive
right, but not the obligation, to acquire land from The Irvine Company for the
development of additional apartment communities on the Irvine Ranch. The
determination to acquire a land site pursuant to the Land Rights Agreement is
made solely by the Independent Directors Committee. The Irvine Company
determines which land will be designated for rental apartment community
development. In addition, The Irvine Company controls the application for
Village Related Entitlements and also has certain approval rights with respect
to the architectural design and physical layout of rental apartment communities.
    
 
     Non-Competition Arrangements. The Irvine Company and Mr. Bren have agreed
not to directly or indirectly acquire or develop, or acquire an equity ownership
interest in any entity that has an ownership interest in, any apartment
community, whether on or off the Irvine Ranch. The prohibition on The Irvine
Company and Mr. Bren from developing apartment communities on the Irvine Ranch
will terminate on
 
                                       57
<PAGE>   59
 
   
July 31, 2020. The Irvine Company and Mr. Bren will remain prohibited from
engaging in any such activity off The Irvine Ranch until the date on which both
of the following conditions are satisfied: (i) no nominee of The Irvine Company
is a member of the Company's Board of Directors and (ii) The Irvine Company and
certain related persons beneficially own less than 20% of the outstanding Common
Stock in the aggregate (including for these purposes shares issuable upon
exchange of its Common L.P. Units pursuant to the Exchange Rights, subject to
the ownership limit provision applicable to The Irvine Company under the
Company's Articles of Incorporation). For a description of the circumstances
under which these non-competition arrangements could be earlier terminated, see
"Risk Factors -- Early Termination of the Exclusive Land Rights and
Non-Competition Arrangements with The Irvine Company and Mr. Bren Would
Adversely Affect the Operating Partnership." In the event the Land Rights
Agreement is terminated, The Irvine Company and Mr. Bren will no longer be
restricted from competing both on and off the Irvine Ranch with the Company or
the Operating Partnership with respect to the ownership and development of
rental apartment communities. As a result, conflicts of interest may arise
between The Irvine Company and Mr. Bren on the one hand and the Operating
Partnership and the Company on the other hand.
    
 
  POLICIES WITH RESPECT TO OTHER ACTIVITIES
 
     The Company has authority to offer shares of its capital stock or other
securities, to cause the Operating Partnership to issue additional Common and
Preferred L.P. Units or other securities, and to repurchase (or cause the
Operating Partnership to repurchase) or otherwise reacquire such capital stock,
L.P. Units or any other securities and may engage in such activities in the
future. Neither the Company nor the Operating Partnership has any outstanding
loans to other entities or persons, including officers and directors of the
Company. The Company may make, or may cause the Operating Partnership in the
future to make, loans to joint ventures in which they participate in order to
meet working capital needs. Neither the Company nor the Operating Partnership
has engaged in trading, underwriting or agency distribution or sale of
securities of other issuers, and neither the Company nor the Operating
Partnership has invested in the securities of other issuers other than in the
case of the Company and the Operating Partnership for the purpose of exercising
control, and neither the Company nor the Operating Partnership intends to do so.
The Company intends to make, and to cause the Operating Partnership to make,
investments in such a way that neither will be treated as an investment company
under the Investment Company Act of 1940.
 
     At all times, the Company intends to cause the Operating Partnership to
make investments in such a manner as to be consistent with the requirements of
the Code for each of the Company and the Trust to qualify as a REIT unless,
because of changing circumstances or changes in the Code (or in Treasury
Regulations), the Required Directors, with the consent of the holders of 66 2/3%
of the outstanding shares of Common Stock, determine that it is no longer in the
best interests of the Company to qualify as a REIT.

     The Company pays its Directors who are neither officers of the Company nor
officers or directors of The Irvine Company fees for their services as
directors. Directors receive annual compensation of $30,000 plus a fee of $1,500
for attendance (in person or by telephone) at each meeting of the Board of
Directors, plus a fee of $750 for attendance, (in person or by telephone) at
each meeting of a committee of the Board of Directors, whether or not such
Committee meeting occurs on the same day as a meeting of the Board of Directors,
plus annual compensation of $3,000 for acting as Chairperson of a standing
committee of the Board of Directors. The Company has also established the 1993
Stock Option Plan for Directors, pursuant to which each Director who: (i) is not
an employee of the Company or any of its subsidiaries or affiliates, (ii) is
unaffiliated with The Irvine Company and Mr. Bren and has not been employed by
The Irvine Company within the preceding five years and (iii) has not received a
stock award within the preceding year under an employee stock plan of the
Company, is awarded an option to purchase 5,000 shares of the Company's Common
Stock upon initial appointment or election to the Board and an option to
purchase 1,000 shares of the Company's Common Stock at each subsequent annual
meeting other than an Eligible Director as defined in the plan first elected to
the Board within the twelve months immediately preceding and including such
meeting. The exercise price of any such option is equal to the fair market value
of the Common Stock on the date of grant. Such options are exercisable at all
times during the period beginning on the date of grant and ending on the earlier
of (i) the tenth anniversary of the date of grant or (ii) the first anniversary
of the date on which the optionee ceases to be an Eligible Director.
 
CERTAIN RIGHTS OF THE IRVINE COMPANY WITH RESPECT TO THE COMPANY'S BOARD OF
DIRECTORS
 
     Pursuant to the Miscellaneous Rights Agreement, The Irvine Company, its
shareholders and affiliates and Mr. Bren and his affiliates (the "Irvine
Persons") have the right, and will continue to have the right so long as the
Irvine Persons beneficially own at least 20% of the outstanding Common Stock of
the Company (including for this purpose Common Stock issuable upon exchange of
Common L.P. Units pursuant to the Exchange Rights), to nominate three persons
(each, an "Irvine Company Board Representative") for election to the Board of
Directors of the Company. In the event this ownership falls below 20% but is at
least 15%, the Irvine Persons will have the right to nominate two persons for
election to the Board of Directors; and if this ownership falls below 15% but is
at least 10%, the Irvine Persons will have the right to nominate one person for
election to the Board of Directors. In connection with the foregoing, The Irvine
Company is authorized to act for the Irvine Persons. The three current Directors
nominated by the Irvine Persons are Messrs. Bren, McKee and Watson.
 
     Two provisions of the Company's Bylaws give The Irvine Company additional
rights with respect to the Company's Board of Directors:
 
     First, the Company's Bylaws provide that a majority of the entire Board of
Directors of the Company including at least one Irvine Company Board
Representative shall constitute a quorum for Board of Directors action at any
meeting.
 
     Second, the Company's Bylaws provide that approval of more than 75% of the
entire Board of Directors is required to approve (i) a change of control (as
defined therein) of the Company or the Operating Partnership; (ii) any amendment
to the Company's Articles of Incorporation or Bylaws or the Partnership
Agreement; (iii) any waiver or modification of the ownership limit provisions of
the Company's Articles of Incorporation; (iv) any merger, consolidation,
statutory share exchange or sale of all or substantially all of the assets of
the Company or the Operating Partnership; (v) subject to certain exceptions, the
issuance of equity securities of the Company; (vi) the Company taking title to
assets or conducting business other than through the Operating Partnership, or
for the Company or the Operating Partnership engaging in another line of
business; (vii) the Company or the Operating Partnership making a general
assignment for the benefit of creditors or instituting (or consent to the
institution of) proceedings in bankruptcy or for the liquidation, dissolution,
reorganization or winding-up of the Company or the Operating Partnership; and
(viii) termination of the Company's status as a REIT for federal income tax
purposes.

nine months ended September 30, 1997 and $2,966,000, $3,010,000 and $3,055,000
for the years ended December 31, 1996, 1995 and 1994, respectively. The mortgage
notes payable to The Irvine Company "wrap around" secured first trust deed notes
payable to third party financial institutions. The secured first trust deed
notes totaled $50,834,000, $51,363,000, $52,030,000 and $52,654,000 as of
September 30, 1997 and December 31, 1996, 1995 and 1994, respectively. The
largest aggregate amount of indebtedness outstanding under each note was

and $18,487,000 and $34,962,000 during 1994. As of September 30, 1997, the
amount outstanding under each note was $17,178,000 and $33,656,000.
 
     The Company, the Operating Partnership and The Irvine Company are parties
to the Land Rights Agreement. This agreement, which extends through July 31,
2020, provides the Company the exclusive right, but not the obligation, to
acquire additional land sites which have been entitled for residential use and
designated by The Irvine Company as ready for apartment development in
accordance with the Master Plan. The determination to exercise an option with
respect to a site is made solely by a majority of the Independent Directors
Committee of the Company's Board of Directors. In addition, The Irvine Company
and Donald Bren have agreed to conduct their apartment community development and
ownership activities on the Irvine Ranch solely through the Operating
Partnership.
 
     Pursuant to the Land Rights Agreement, The Irvine Company and Mr. Bren have
agreed not to directly or indirectly acquire or develop, or acquire an equity
interest in any entity that has an ownership interest in, any rental apartment
community whether on or off the Irvine Ranch. This prohibition terminates, with
respect to communities on the Irvine Ranch, on July 31, 2020, and with respect
to communities off the Irvine Ranch, when (i) no nominee of The Irvine Company
is a member of the Company's Board of Directors and (ii) The Irvine Company and
certain related persons beneficially own less than 20% of the outstanding Common
Stock in the aggregate (including for this purpose Common Stock issuable upon
exchange of Common L.P. Units).
 
     The Land Rights Agreement is subject to early termination upon the
occurrence of certain events including (i) the failure of the shareholders of
the Company to elect as directors of the Company the number of directors which
The Irvine Company is entitled to nominate to the Company's Board of Directors,
(ii) in the event of a vacancy on the Board of Directors of an Irvine Company
Board Representative, the remaining directors shall not promptly elect a person
designated by The Irvine Company to fill such vacancy and (iii) during the
period The Irvine Company has the right to nominate three persons to the
Company's Board of Directors, the provisions of the Articles of Incorporation
and the Bylaws requiring approval of the Required Directors to take certain
actions shall be repealed, modified or amended without the prior written consent
of The Irvine Company.
 
   
     Under the terms of the Land Rights Agreement, through July 31, 2000, the
purchase price for any apartment community sites acquired may be paid with
either cash, Common Stock or Common L.P. Units, at the option of the Company.
After July 31, 2000, the choice of consideration will revert to The Irvine
Company. In no event shall the purchase price for any community land site exceed
95% of the value of such site as determined by independent appraisals. In
addition, the purchase price for apartment sites encompassing the first 1,800
apartment units the Operating Partnership develops starting in mid-1995 will be
set at an amount such that each project's budgeted pro forma unleveraged return
on costs for the first 12 months following stabilized occupancy will be between
10.0% and 10.5%. Seven land sites discussed below have been
    
 
                                       71
<PAGE>   73
 
   
purchased under this arrangement which will contain a total of 1,884 apartment
units. Accordingly, as of the date of this prospectus the purchase price for all
future land acquisitions under the Land Rights Agreement will be no greater than
95% of the appraised value.
    
 
     In the third quarter of 1994, the Operating Partnership acquired four sites
for development of 1,695 units for $19,703,000 from The Irvine Company. As
partial financing for these four sites, the Operating Partnership elected to
assume $15,656,000 in tax-exempt assessment district debt and paid $4,047,000 in
cash.
 
     In March 1995, the Operating Partnership acquired a 512-unit development
site known as Newport Ridge for $9,542,000 from The Irvine Company. As partial
financing for the acquisition of the site, The Company elected to assume
$4,184,000 in tax-exempt assessment district debt. The balance of $5,358,000 was
paid through the issuance of 336,432 additional Common L.P. Units in the
Operating Partnership to The Irvine Company. In November 1995, the Operating
Partnership acquired a 300-unit development site known as Baypointe from The
Irvine Company for $4,190,000, of which $2,223,000 was paid in cash and
$1,967,000 was paid through the issuance of 113,372 additional Common L.P. Units
in the Operating Partnership to The Irvine Company. The L.P. Units are
exchangeable for Common Stock of the Company on a one for one basis, subject to
adjustment and certain limitations.
 
     In March 1996, the Operating Partnership acquired a 227-unit development
site known as Santa Maria for $3,343,000 from The Irvine Company. As partial
financing for the acquisition of the site, the Operating Partnership elected to
assume $2,771,000 in tax-exempt assessment district debt. The balance of
$572,000 was paid through the issuance of 28,358 additional Common L.P. Units in
the Operating Partnership to The Irvine Company. In July 1996, the Operating
Partnership acquired a 245-unit development site known as The Colony for
$3,545,000 from The Irvine Company. The purchase price for this site consisted
of the issuance of 115,544 additional Common L.P. Units in the Operating
Partnership and $1,143,000 in cash. In December 1996, the Operating Partnership
acquired a 207-unit development site known as Santa Rosa II for $5,999,000 from
The Irvine Company. The purchase price was paid through the issuance of 244,857
additional Common L.P. Units in the Operating Partnership. The foregoing Common
L.P. Units are exchangeable for Common Stock of the Company on a one for one
basis, subject to adjustment and certain limitations.
 
   
     On February 10, 1997, the Operating Partnership acquired a 316-unit
development site known as Rancho Santa Fe for $8,408,000 from The Irvine
Company. The purchase price was paid through the issuance of 313,439 additional
Common L.P. Units in the Operating Partnership. On October 21, 1997, the
Operating Partnership acquired a 196-unit development site for $5,697,000 from
The Irvine Company and on December 16, 1997 the Operating Partnership acquired a
393-unit development site for $10,325,000 from The Irvine Company. The purchase
price for these two sites was paid through the issuance of 179,433 and 332,060
additional Common L.P. Units, respectively, in the Operating Partnership.
Pursuant to the terms of each of these three acquisitions, a portion of the
purchase price is refundable through the forfeiture of a portion of the Common
L.P. Units issued in the transaction, if the apartment community to be
constructed on the site does not achieve a 10% unleveraged return on costs for
the first twelve months following stabilized occupancy. The foregoing Common
L.P. Units are exchangeable for Common Stock of the Company on a one for one
basis, subject to adjustment and certain limitations.
    
 
     Independent appraisals were obtained for each of the sites referred to
above, prior to the Independent Directors Committee determining that the
Operating Partnership would exercise its right to purchase such land sites. If
the Operating Partnership elects not to exercise its option for any site, the
Operating Partnership will thereafter have a right of first refusal on the sale
of such site to a third party if the terms of such sale are more favorable than
those offered to the Operating Partnership. The determination to exercise an
option or the right of first refusal under the Land Rights Agreement with
respect to any site will be made solely by a majority of the Independent
Directors Committee.
 
   
     In December 1997, the Operating Partnership acquired a 336-unit development
site in the master planned community of Stonecrest Village in San Diego County
from an affiliate of The Irvine Company controlled by Donald Bren, the Chairman
of the Board of Directors of the Company. The purchase price for the site of
$9,475,00 was paid through the issuance of 305,707 additional Common L.P. Units
in the Operating
    
 
                                       72

Partnership, of which 191,011 Common L.P. Units are exchangeable for Common
Stock of the Company on a one for one basis, subject to adjustment and certain
limitation, with the remainder not being exchangeable for Common Stock absent
approval of the stockholders of the Company. Independent appraisals were
obtained for this site prior to the Independent Directors Committee determining
that the Operating Partnership would purchase such site.
    
 
     Three directors of the Company, Messrs. Bren, Watson and McKee, are
affiliated with The Irvine Company. Mr Bren is Chairman of the Board and the
majority stockholder of The Irvine Company. Mr. Watson is Vice Chairman of the
Board of The Irvine Company. Mr. McKee is Executive Vice President and Chief
Financial Officer of The Irvine Company.
 
OTHER TRANSACTIONS
 
     Mr. Grundhofer is Chairman, President and Chief Executive Officer of First
Bank System, Inc. which, through an affiliate, is a member of the bank syndicate
that has provided the Operating Partnership's $250 million Credit Facility. This
facility replaced various prior facilities in which this bank also participated.
$36.0 million was outstanding under the Credit Facility as of October 31, 1997.
Based on this bank's percentage participation in the Credit Facility (and the
predecessor facilities), the Company estimates that the amount of interest and
fees paid to the affiliate totaled $271,000 during the first nine months of 1997
and $245,000, $388,000 and $96,000 for 1996, 1995 and 1994, respectively. In
addition, an affiliate of First Bank System, Inc. acts as trustee for the 7%
Notes and will receive customary compensation therefor.

                DESCRIPTION OF THE SERIES A PREFERRED SECURITIES
 
     The Common Securities and the Series A Preferred Securities will be issued
pursuant to the terms of the Declaration. The following summarizes the material
terms and provisions of the Common Securities and the Series A Preferred
Securities and is qualified in its entirety by reference to the Business Trust
Act and the Declaration, which has been filed as an exhibit to the Registration
Statement of which this Prospectus forms a part.
 
GENERAL
 
   
     The Declaration authorizes the Trust to issue up to 25 million Preferred
Securities in one or more series, including the Series A Preferred Securities,
up to 10,000 Common Securities and up to 25 million securities of a class
designated Excess Preferred Securities issuable in one or more series as
described below under "Restrictions on Ownership and Transfer of Series A
Preferred Securities." The Regular Trustees have the authority to establish the
terms of each series of Preferred Securities, including the preferences,
conversion and other rights, voting powers, restrictions, limitations as to
distributions, qualifications and terms and conditions of redemption, if any, by
amending the Declaration. Such amendments do not require any vote or action of
the holders of the Preferred Securities except as otherwise set forth in the
Declaration or as required by law or the rules of any stock exchange or
automated quotation system on which the Preferred Securities are listed. The
Preferred Securities and the Common Securities represent undivided beneficial
interests in the assets of the Trust, subject to the priority and payment terms
of the Trust Securities, and are not secured by any assets of the Operating
Partnership or any of its affiliates. All of the Common Securities will be
owned, directly or indirectly, by the Company and certain members of the
management of the Company. The Declaration does not permit the issuance by the
Trust of any securities or other evidences of beneficial ownership of, or
beneficial interests in, the Trust other than the Preferred Securities which
have terms substantially similar to the series of Preferred L.P. Units of the
Operating Partnership purchased by the Trust with the proceeds from the issuance
of such series of Preferred Securities, the Excess Preferred Securities and the
Common Securities, the incurrence of any indebtedness for borrowed money by the
Trust or the making of any investment other than in Preferred L.P. Units of the
Operating Partnership and the investment of the proceeds of the sale of the
Common Securities in an interest bearing account at, or certificate of deposit
of, a bank. Pursuant to the Declaration, the Property Trustee will own and hold
the Preferred L.P. Units of the Operating Partnership as trust assets for the
benefit of the holders of the Trust Securities.
    
 
   
     Application will be made to list the Series A Preferred Securities on the
NYSE under the symbol "IAC Pr A". If approved for listing, trading of the Series
A Preferred Securities on the NYSE is expected to commence within 30 days after
the date of this Prospectus. While the Underwriters have advised the Trust that
they intend to make a market in the Series A Preferred Securities prior to
commencement of trading on the NYSE, they are under no obligation to do so and
no assurance can be given that a market for the Series A Preferred Securities
will exist prior to commencement of trading.
    
 
COMMON SECURITIES
 
   
     Subject to the preferential rights of the Series A Preferred Securities
(and the related series of Excess Preferred Securities as described below) and
such preferential rights as may be granted by the Regular Trustees in connection
with the future issuance of Preferred Securities (and any related series of
Excess Preferred Securities as described below), holders of Common Securities
are entitled to one vote per security on all matters submitted for a vote to the
holders of Common Securities and, subject to the terms of the Declaration or any
series of Preferred Securities hereafter established, the exclusive voting power
for all purposes (including amendments to the Declaration) are vested in the
holders of the Common Securities. Subject to the preferential rights of the
Series A Preferred Securities and any series of Preferred Securities hereafter
established, the holders of Common Securities are entitled to receive ratably
such distributions as may be declared from time to time on the Common Securities
by a majority of the Regular Trustees in their discretion from funds legally
available therefor. In the event of the liquidation, dissolution, winding-up or
termination of the Trust, after payment of all debt and other liabilities and
any liquidation amount with respect
    
 
                                       74
<PAGE>   76
 
   
to outstanding series of Preferred Securities (and any related series of Excess
Preferred Securities as described below), each holder of Common Securities is
entitled to receive, ratably with each other holder of Common Securities, all
remaining assets of the Trust available for distribution to the holders of
Common Securities. Holders of Common Securities have no subscription,
redemption, conversion or preemptive rights. Matters submitted for approval to
holders of Common Securities generally require a majority vote of the Common
Securities present and voting thereon. The holders of Common Securities have the
exclusive right (subject to the terms of the Declaration) to appoint, remove or
replace Trustees and to increase or decrease the number of Trustees, subject to
the right of holders of the Series A Preferred Securities (and any other series
of Preferred Securities having a similar right which is then exercisable) to
appoint a Special Regular Trustee upon the occurrence of an Appointment Event.
The outstanding shares of Common Securities are fully paid and nonassessable.
    
 
RESTRICTIONS ON OWNERSHIP AND TRANSFER OF SERIES A PREFERRED SECURITIES
 
     Ownership Limit Provisions. The Declaration contains certain restrictions
on the number of Series A Preferred Securities that individual holders may own.
For the Trust to qualify as a REIT under the Code, no more than 50% in value of
the outstanding Trust Securities may be owned, directly or indirectly, by five
or fewer individuals (as defined in the Code to include certain entities) during
the last half of a taxable year (other than the first year) or during a
proportionate part of a shorter taxable year. The Trust Securities must also be
beneficially owned by 100 or more persons during at least 335 days of a taxable
year or during a proportionate part of a shorter taxable year. Because the Trust
expects to qualify as a REIT, the Declaration contains restrictions on the
acquisition of Series A Preferred Securities intended to ensure compliance with
these requirements.
 
     Subject to certain exceptions specified in the Declaration no holder may
own, or be deemed to own by virtue of the attribution provisions of the Code,
more than 9.8%, (the "Ownership Limit") of the issued and outstanding Series A
Preferred Securities. The Regular Trustees may, with a ruling from the IRS or an
opinion of counsel satisfactory to it, waive the Ownership Limit with respect to
a holder if such holder's ownership will not then or in the future jeopardize
the Trust's status as a REIT.
 
     If Series A Preferred Securities in excess of the Ownership Limit are
issued or transferred to any person, or Series A Preferred Securities which
would cause the Trust to be beneficially owned by fewer than 100 persons are
transferred to any person, such issuance or transfer shall be null and void and
the intended transferee will acquire no rights to the stock.
 
     In addition, Series A Preferred Securities owned, or deemed to be owned, or
transferred to a holder in excess of the Ownership Limit will automatically be
exchanged for a series of a separate class of preferred securities of the Trust
("Excess Preferred Securities") that shall be deemed to have been transferred to
a person as trustee of a trust for the exclusive benefit of one or more
charitable organizations designated by the Regular Trustees. While Excess
Preferred Securities are held in trust, the trustee of the trust will be deemed
to hold the Excess Preferred Securities for the exclusive benefit of the
charitable beneficiary, the intended original transferee-holder will acquire no
rights to such securities except as described below, and the trustee of the
trust will have all distribution and voting rights pertaining to the transferred
securities. Upon liquidation, dissolution or winding-up of the Trust, the
intended original transferee-holder's ratable share of the Trust's assets would
be limited to the price paid by the original transferee-holder for the Series A
Preferred Securities in the purported transfer that resulted in the Excess
Preferred Securities or, if no value was given, the price per security equal to
the closing market price on the date of the purported transfer that resulted in
the Excess Preferred Securities.
 
     Excess Preferred Securities are not transferable except as hereinafter
described. The original transferee-holder may, at any time the Excess Preferred
Securities are held in trust as provided above, transfer the Excess Preferred
Securities to any person whose ownership of such Preferred Securities would be
permitted under the Ownership Limit, at a price per security not in excess of
the lesser of (i) the price per security paid by the original transferee-holder
for the Series A Preferred Securities that resulted in the Excess Preferred
Securities or, if no value was given, the price per security equal to the
closing market price on the date of the purported
 
                                       75
<PAGE>   77
 
transfer that resulted in the Excess Preferred Securities or (ii) the price per
security received by the original transferee-holder in the transfer to the
person whose ownership of such securities would be permitted under the Ownership
Limit. Immediately upon transfer to such permitted transferee, the Excess
Preferred Securities will automatically be exchanged for Series A Preferred
Securities. In addition, the Trust (or its designee) would have the right, for a
period of 90 days during the time the Excess Preferred Securities are held in
trust, to purchase all or any portion of the Excess Preferred Securities from
the original transferee-holder at a price per security equal to the lesser of
(i) the price per security paid by the original transferee-holder in the
transaction that created such Excess Preferred Securities (or, in the case of a
devise or gift, the closing market price at the time of such devise or gift) and
(ii) the closing market price for the security on the date the Trust (or its
designee) exercises its option to purchase. The 90-day period begins on the date
of the violative transfer if the original transferee-holder gives notice to the
Trust of the transfer or (if no such notice is given) the date the Regular
Trustees determine that a violative transfer has been made.
 
   
     The Ownership Limit will not be automatically removed even if the REIT
provisions of the Code are changed so as to no longer contain any ownership
concentration limitation or if the ownership concentration limitation is
increased. Any change in the Ownership Limit would require an amendment to the
Declaration. Such an amendment to the Declaration would require the affirmative
vote of holders owning not less than 66 2/3% of the outstanding Common
Securities. No vote of holders of Preferred Securities will be required in
connection with any such act.
    
 
     All certificates representing Series A Preferred Securities will bear a
legend referring to the restrictions described above.
 
     All persons who own, directly or by virtue of the attribution provisions of
the Code, more than 0.5% (or such other percentage between 0.5% and 5%, as
determined by the Regular Trustees) of the outstanding Series A Preferred
Securities must file an affidavit with the Trust containing the information
specified in the Declaration within 30 days after January 1 of each year. In
addition, each holder of Series A Preferred Securities shall upon demand be
required to disclose to the Trust in writing such information with respect to
the direct, indirect and constructive ownership of Series A Preferred Securities
as the Regular Trustees deem necessary to comply with the provisions of the Code
applicable to a REIT or to comply with the requirements of any taxing authority
or governmental agency.
 
     If the Trust authorizes the issuance of any other series of Preferred
Securities in the future, the Regular Trustees will at the time of authorization
establish ownership limits applicable to such series to ensure compliance with
the REIT qualification provisions of the Code.
 
RANKING
 
   
     The Series A Preferred Securities will, with respect to distributions and
rights upon liquidation, dissolution, winding-up or termination of the Trust,
rank (i) senior to the Common Securities and (ii) on a parity with all other
series of Preferred Securities issued by the Trust unless the terms of such
other series specifically provide that such other series ranks junior to the
Series A Preferred Securities.
    
 
DISTRIBUTIONS
 
   
     Subject to the rights of holders of other series of Preferred Securities
ranking on a parity with the Series A Preferred Securities as to the payment of
distributions which may from time to time be issued by the Trust, holders of
Series A Preferred Securities will be entitled to receive, when, as and if
declared by the Regular Trustees out of funds legally available therefor,
cumulative cash distributions at the rate per annum of   % of the stated
liquidation amount of $25 per Series A Preferred Security. Distributions on the
Series A Preferred Securities will be cumulative, will accrue from the original
date of issuance and will be payable quarterly in arrears, on             ,
            ,             and             (each a "Series A Distribution Payment
Date") of each year, commencing on             , 1998. The amount of
distributions payable for any period will be computed on the basis of a 360-day
year of twelve 30-day months and for any period shorter than a full quarterly
period for which distributions are computed, the amount of the distribution
payable will be computed on the basis of the actual number of days elapsed in
such a 30-day month. If any Series A
    
 
                                       76
<PAGE>   78
 
   
Distribution Date is not a Business Day, the payment of the distribution to be
made on such Series A Distribution Payment Date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date. "Business Day" shall mean any day other than Saturday, Sunday or
any other day on which banking institutions in New York, New York or Los
Angeles, California are authorized or required by any applicable law to close.
Distributions on the Series A Preferred Securities will accrue whether or not
the Trust has earnings, whether or not there are funds legally available for the
payment of such distributions and whether or not such distributions are
declared. Accrued distributions will accumulate, to the extent they are not
paid, as of the Series A Distribution Payment Date on which they first become
payable. Accumulated and unpaid distributions will not bear interest.
    
 
   
     If declared by the Regular Trustees as provided above, distributions on the
Series A Preferred Securities must be paid on the dates payable to the extent
that the Property Trustee has cash on hand in the Property Account to permit
such payment. So long as the Series A Preferred L.P. Units are the sole assets
of the Trust, the funds available for distribution to the holders of the Series
A Preferred Securities will be limited to payments received by the Property
Trustee in respect of the Series A Preferred L.P. Units that are deposited in
the Trust as trust assets. See "Description of the Series A Preferred L.P.
Units." If the Operating Partnership does not make a distribution on the Series
A Preferred L.P. Units, the Property Trustee will not make distributions on the
Series A Preferred Securities.
    
 
   
     So long as any Series A Preferred Securities are outstanding, no
distribution shall be paid or declared on or with respect to the Common
Securities or any other series of outstanding Preferred Securities ranking
junior as to the payment of distributions to the Series A Preferred Securities
(collectively, the "Junior Securities"), nor shall any sum or sums be set aside
for or applied to the purchase or redemption of the Series A Preferred
Securities or any other series of outstanding Preferred Securities or the
purchase, redemption or other acquisition for value of any Junior Securities
unless, in each case, full cumulative distributions accumulated on all Series A
Preferred Securities and all other series of outstanding Preferred Securities
ranking on a parity with the Series A Preferred Securities as to the payment of
distributions have been paid in full, provided that the foregoing will not
prohibit distributions payable solely in Junior Securities and the purchase of
Preferred Securities of any series as described under "-- Restrictions on
Ownership and Transfer of Series A Preferred Securities." When distributions
have not been paid in full upon the Series A Preferred Securities on the
applicable Series A Distribution Payment Date (or a sum sufficient for such full
payment is not set apart therefor), all distributions declared and paid on the
Series A Preferred Securities and any other series of outstanding Preferred
Securities ranking on a parity with the Series A Preferred Securities as to the
payment of distributions shall be declared and paid so that the amount of
distributions declared and paid on the Series A Preferred Securities and such
other series of Preferred Securities shall in all cases bear to each other the
same ratio that the respective distribution rights of the Series A Preferred
Securities and such other series of Preferred Securities (which shall not
include any accumulation in respect of unpaid distributions for prior
distribution periods if such other series of Preferred Securities do not have
cumulative distribution rights) bear to each other. Holders of Series A
Preferred Securities shall not be entitled to any distributions, whether payable
in cash, property or otherwise, in excess of the full cumulative distributions
described herein.
    
 
   
     Distributions on the Series A Preferred Securities will be made to the
holders thereof as they appear on the books and records of the Trust on the
relevant record dates, which, as long as the Series A Preferred Securities
remain in book-entry form, will be one Business Day prior to the relevant Series
A Distribution Payment Date. Distributions on the Series A Preferred Securities
will be paid through the Property Trustee who will hold amounts received in
respect of the Preferred L.P. Units in the Property Account. Subject to any
applicable laws and regulations and the provisions of the Declaration, each such
payment to the Series A Preferred Securityholders will be made as described
under "-- Book-Entry Only Issuance -- The Depository Trust Company" below. In
the event that the Series A Preferred Securities do not continue to remain in
book-entry only form, the Regular Trustees shall have the right to select
relevant record dates, which shall be more than one Business Day prior to the
relevant Series A Distribution Payment Dates.

REDEMPTION
    
 
   
     The Series A Preferred Securities cannot be redeemed prior to
except in the case of a Special Event as defined under "Description of the
Series A Preferred L.P. Units -- Redemption."
    
 
   
     Upon the repayment of the Series A Preferred L.P. Units or another series
of Preferred L.P. Units issued by the Trust in the future, whether at their
stated maturity, upon termination of the Operating Partnership, upon redemption
or otherwise, the proceeds from such repayment or payment will be promptly
applied to redeem a series of Preferred Securities having economic rights
substantially similar to the Preferred L.P. Units so repaid, any such redemption
to be in an aggregate liquidation amount equal to the aggregate stated value of
the Preferred L.P. Units so repaid, upon not less than 30 nor more than 60 days'
notice. Accordingly, if the Series A Preferred L.P. Units are repaid, whether at
their stated maturity, upon termination of the Operating Partnership, upon
redemption or otherwise, Series A Preferred Securities having an aggregate
liquidation amount equal to the Series A Preferred L.P. Units so repaid will be
redeemed for cash by the Trust at the Redemption Price. In the event fewer than
all outstanding Series A Preferred Securities are to be redeemed, Series A
Preferred Securities registered in the name of and held by DTC or its nominee
will be redeemed as described under "-- Book-Entry Only Issuance -- The
Depository Trust Company" below. The Operating Partnership will terminate on
December 31, 2092, unless sooner dissolved.
    
 
   
     If a partial redemption of the Series A Preferred Securities would result
in the delisting of the Series A Preferred Securities by any national securities
exchange or other organization on which the Series A Preferred Securities are
then listed, the Trust will only redeem the Series A Preferred Securities in
whole.
    
 
   
     The Series A Preferred Securities have a stated maturity of December 31,
2092 (see "Liquidation" below) and will not be subject to any sinking fund. The
Series A Preferred Securities may be mandatorily purchased by the Trust as
described under "-- Restrictions on Ownership and Transfer of Series A Preferred
Securities."
    
 
REDEMPTION PROCEDURES
 
   
     The Trust may not redeem fewer than all the outstanding Series A Preferred
Securities unless all accrued and unpaid distributions have been paid on all
Series A Preferred Securities for all quarterly distribution periods terminating
on or prior to the date of redemption.
    
 
   
     If the Trust gives a notice of redemption in respect of Series A Preferred
Securities (which notice will be irrevocable) then by 12:00 noon, New York City
time, on the redemption date and provided that the Property Trustee has funds
sufficient to pay the Redemption Price the Property Trustee will deposit
irrevocably with the DTC (or its successor) funds sufficient to pay such
Redemption Price and will give the DTC (or its successor) irrevocable
instructions and authority to pay the Redemption Price to the holders of the
Series A Preferred Securities entitled thereto. See "-- Book-Entry Only
Issuance -- The Depository Trust Company." If notice of redemption shall have
been given as provided above and funds deposited as required, then, on the date
of such deposit, distributions will cease to accrue on the Series A Preferred
Securities called for redemption, such Series A Preferred Securities will no
longer be deemed to be outstanding and all rights of holders of such Series A
Preferred Securities so called for redemption will cease, except the right of
the holders of such Series A Preferred Securities to receive the Redemption
Price but without interest thereon. Neither the Trustees nor the Trust shall be
required to register or cause to be registered the transfer of any Series A
Preferred Securities which have been so called for redemption. If any date fixed
for redemption of Series A Preferred Securities is not a Business Day, then
payment of the Redemption Price payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such Business Day falls in the
next calendar year, such payment will be made on the immediately preceding
Business Day, in each case with the same force and effect as if made on such
date fixed for redemption. If payment of the Redemption Price in respect of
Series A Preferred Securities is improperly withheld or refused and not paid by
the Property Trustee, distributions on such Series A Preferred Securities will
continue to accrue, from the original redemption date to the date of payment, in
which case the actual payment date will be used for purposes of calculating the
Redemption Price.

<PAGE>   80
 
   
     The Regular Trustees, on behalf of the Trust, will provide notice of any
redemption of the Series A Preferred Securities to the holders of record thereof
not less than 30 nor more than 60 days prior to the date of redemption. Such
notice shall be provided by mailing notice of such redemption, first class
postage prepaid, to each holder of Series A Preferred Securities to be redeemed,
at such holder's address as it appears on the transfer records of the Trust.
Each notice shall state the following: (i) the redemption date; (ii) the
Redemption Price; (iii) the place or places where certificates for the Series A
Preferred Securities may be surrendered for payment; (iv) the number of Series A
Preferred Securities to be redeemed from each holder; (v) that payment of the
Redemption Price will be made upon presentation and surrender of such Series A
Preferred Securities; and (vi) that on or after the redemption date
distributions on the Series A Preferred Securities to be redeemed will cease to
accrue. No failure to give or defect in a notice of redemption shall affect the
validity of the proceedings for redemption except as to the holder to which
notice was defective or not given.
    
 
   
     Subject to the foregoing and applicable law (including, without limitation,
United States federal securities laws), the Operating Partnership or any of its
subsidiaries may at any time and from time to time purchase outstanding Series A
Preferred Securities by tender, in the open market or by private agreement
unless at such time, the Operating Partnership would be prohibited from
purchasing or redeeming Series A Preferred L.P. Units pursuant to the terms
thereof. See "Description of the Series A Preferred L.P. Units --
Distributions."
    
 
LIQUIDATION
 
   
     Subject to the rights of holders of any other series of Preferred
Securities which the Trust may issue in the future which rank on a parity with
the Series A Preferred Securities upon any voluntary or involuntary dissolution,
liquidation, winding-up or termination of the Trust, the holders of the Series A
Preferred Securities will be entitled to receive upon any such dissolution,
liquidation, winding-up or termination of the Trust out of the assets of the
Trust legally available for distribution, after payment or provision for payment
of debts and other liabilities of the Trust (to the extent not satisfied by the
Operating Partnership as provided in the Declaration), an amount per Series A
Preferred Security equal to $25 per Series A Preferred Security plus accrued and
unpaid distributions thereon to the date of payment (such amount being the
"Liquidation Distribution") and no more.
    
 
   
     If, upon any liquidation, dissolution, winding-up or termination of the
Trust, there are insufficient assets to permit full payment to holders of Series
A Preferred Securities and any other series of outstanding Preferred Securities
ranking on a parity upon liquidation, dissolution, winding-up or termination of
the Trust with the Series A Preferred Securities, the holders of Series A
Preferred Securities and such other series of Preferred Securities shall be paid
ratably in proportion to the full distributable amounts to which holders of
Series A Preferred Securities and such other series of Preferred Securities are
respectively entitled upon liquidation, dissolution, winding-up or termination.
The full preferential amount payable to holders of Series A Preferred Securities
and such other series of outstanding Preferred Securities upon any such
liquidation, dissolution, winding-up or termination will be paid in full before
any distribution or payment is made to holders of Common Securities or Preferred
Securities of any series ranking junior to the Series A Preferred Securities
upon liquidation, dissolution, winding up or termination of the Trust. Neither
the consolidation or merger of the Trust with or into any trust, corporation or
other entity (or of any trust, corporation or other entity with or into the
Trust) nor the sale, lease or conveyance of all or substantially all of the
property of the Trust in conformity with the terms of the Declaration shall be
deemed to constitute a liquidation, dissolution, winding-up or termination of
the Trust.
    
 
   
     Pursuant to the Declaration, the Trust shall terminate: (i) on December 31,
2092, unless sooner dissolved as provided in the Declaration, (ii) upon
termination of the Operating Partnership on December 31, 2092, unless sooner
dissolved, or (iii) when (A) Preferred Securities of all series shall have been
repaid in accordance with the terms thereof or called for redemption and the
amounts necessary for redemption thereof shall have been paid to the holders
thereof in accordance with the priority and payment terms of the Preferred
Securities and (B) all of the Common Securities are no longer outstanding.

<PAGE>   81
 
MERGER, CONSOLIDATION OR AMALGAMATION OF THE TRUST
 
   
     The Trust may not consolidate, amalgamate, merge with or into, or convey,
transfer or lease its assets substantially as an entirety to, any corporation or
other entity, except as described below. The Trust may, at the request of the
holders of the Common Securities and with the consent of the Regular Trustees,
but without the consent of the holders of the Preferred Securities, the Property
Trustee or the Delaware Trustee consolidate, amalgamate, merge with or into, any
trust, partnership, corporation or other entity organized under the laws of any
State of the United States or the District of Columbia; provided, that (i) if
the Trust is not the survivor, such successor entity either (x) expressly
assumes all of the obligations of the Trust under the Trust Securities or (y)
substitutes for the Preferred Securities of each series outstanding other
securities having substantially the same terms as the Preferred Securities (the
"Successor Securities"), so long as each series of Successor Securities rank the
same as the Preferred Securities rank with respect to distributions and payments
upon liquidation, dissolution, winding-up or termination, (ii) the Company and
the Operating Partnership expressly acknowledge a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of the Preferred Securities but only if in the opinion of nationally
recognized independent counsel to the Trust experienced in matters under the
Investment Company Act of 1940, as amended (the "1940 Act"), such action is
necessary so that the successor entity will not be required to register as an
"investment company" under the 1940 Act, (iii) the Preferred Securities or any
Successor Securities are listed, or any Successor Securities will be listed upon
notification of issuance, on any national securities exchange, interdealer
quotation system or with another organization on which the Preferred Securities
are then listed or quoted, (iv) such merger, consolidation or amalgamation does
not cause the Preferred Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization or (v)
such merger, consolidation, amalgamation does not adversely affect the powers,
special rights, preferences and privileges of the holders of the Preferred
Securities (including any Successor Securities) in any material respect.
    
 
VOTING RIGHTS
 
   
     Except as provided below, under "-- Modification and Amendment of the
Declaration" and as otherwise required by the Business Trust Act and the
Declaration, the holders of the Series A Preferred Securities will have no
voting rights.
    
 
   
     If the Trust fails to make distributions in full on the Series A Preferred
Securities for six consecutive quarterly distribution periods, (an "Appointment
Event"), then the holders of the Series A Preferred Securities (voting
separately as a class with all other series of Preferred Securities upon which
like voting rights have been conferred and are then exercisable) will be
entitled, by the vote of holders of such Preferred Securities representing a
majority in aggregate liquidation amount of such outstanding Preferred
Securities, to appoint a Special Regular Trustee (who need not be an officer or
an employee of or otherwise affiliated with the Company or the Operating
Partnership) who shall have the same rights, powers and privileges under the
Declaration as a Regular Trustee. The Special Regular Trustee so appointed
shall, without any further act or vote by the holders of any other series of
Preferred Securities, be deemed to have been appointed to act in such capacity
for all series of Preferred Securities upon which like voting rights have been
conferred and are, or in the future become, exercisable. Any holder of Series A
Preferred Securities (other than the Company or the Operating Partnership or any
of their affiliates) shall have the right to nominate any person to be appointed
as Special Regular Trustee. For purposes of determining whether the Trust has
failed to pay distributions in full for six consecutive quarterly distribution
periods, distributions shall be deemed to remain in arrears, notwithstanding any
payments in respect thereof, until full cumulative distributions have been or
contemporaneously are paid with respect to all quarterly distribution periods
terminating on or prior to the date of payment of such cumulative distributions.
Not later than 30 days after such right to appoint a Special Regular Trustee
arises, the Regular Trustees will convene a meeting for the purpose of
appointing a Special Regular Trustee. If the Regular Trustees fails to convene
such meeting within such 30-day period, the holders of Series A Preferred
Securities and any other series of Preferred Securities upon which like voting
rights have been conferred and are then exercisable representing 10% in
aggregate liquidation amount of such outstanding Preferred Securities will be
entitled to convene such meeting. The provisions of the Declaration relating to
the
    
 
                                       80
<PAGE>   82
 
   
convening and conduct of the meetings of the holders will apply with respect to
any such meeting. If, at any such meeting, holders of less than a majority in
aggregate liquidation amount of Preferred Securities of all series entitled to
vote for the appointment of a Special Regular Trustee vote for such appointment,
no Special Regular Trustee shall be appointed. Any Special Regular Trustee may
be removed without cause at any time by vote of the holders of a majority in
liquidation amount of each series of Preferred Securities upon which like voting
rights have been conferred and are then exercisable voting as a single class.
The holders of 10% in liquidation amount of the Series A Preferred Securities
will be entitled to convene such a meeting. Any Special Regular Trustee
appointed shall cease to be a Special Regular Trustee if the Appointment Event
pursuant to which the Special Regular Trustee was appointed and all other
Appointment Events have been cured and cease to be continuing.
    
 
   
     If any proposed amendment or modification of the Declaration would
materially and adversely affect the powers, privileges, preferences or special
rights of the Series A Preferred Securities, then the holders of outstanding
Series A Preferred Securities will be entitled to vote on such amendment or
proposal as a class, and such amendment or proposal shall not be effective
except with the approval of the holders of Series A Preferred Securities
representing 66 2/3% in liquidation amount of the outstanding Series A Preferred
Securities; provided, however, that any such amendment or modification which
would (i) increase the number of authorized securities that the Trust is
authorized to issue, (ii) decrease the number of Preferred Securities of a
series but not below the number of Preferred Securities of the series then
outstanding or (iii) authorize, create or issue any additional series of
Preferred Securities on a parity with or junior to the Series A Preferred
Securities as to distributions or upon liquidation, dissolution, winding-up or
termination of the Trust shall be deemed not to materially and adversely affect
such powers, special rights, preferences or privileges; and provided, further,
if holders of Series A Preferred Securities have a right to vote as provided in
this paragraph but such amendment or proposal arises out of, or is substantially
similar to, an amendment or modification of the Partnership Agreement as
described in the following paragraph and with respect to which the Property
Trustee is required to obtain the direction of holders of Series A Preferred
Securities as described below, then, to the extent permitted by applicable law,
no separate vote pursuant to the Declaration shall be required and the vote
obtained in connection with the Property Trustee seeking the direction of
holders of Series A Preferred Securities shall constitute complete and
sufficient action with respect to such amendment or modification of the
Declaration.
    
 
   
     The Property Trustee shall take any legal action which arises out of or in
connection with the holding of Preferred L.P. Units or the Property Trustee's
duties and obligations under the Declaration or the Business Trust Act. If the
Property Trustee fails to take such legal action, a majority in aggregate
liquidation amount of the Preferred Securities may direct the Property Trustee
to take such legal action. If the Property Trustee fails to enforce its rights
under the Operating Partnership Limited Partnership Agreement, any holder of
Preferred Securities may institute a legal proceeding directly against the
Operating Partnership to enforce such rights, without first instituting a legal
proceeding against the Property Trustee or any other person.
    
 
   
     In the event the consent or vote of the Property Trustee as the holder of
the Series A Preferred L.P. Units of the Operating Partnership is required with
respect to any amendment or modification of the Partnership Agreement, the
Property Trustee shall request the direction of the holders of the Series A
Preferred Securities with respect to such amendment or modification. With
respect to such amendment or modification, the Property Trustee shall vote the
Series A Preferred L.P. Units as directed by a majority in aggregate liquidation
amount of the Series A Preferred Securities; provided that where such amendment
or modification under the Partnership Agreement requires the consent of holders
of Series A Preferred L.P. Units representing a specified percentage greater
than a majority in aggregate liquidation amount of the Series A. Preferred L.P.
Units, the Property Trustee may only give such consent at the direction of the
holders of Series A Preferred Securities representing such specified percentage
of the aggregate liquidation amount of the Series A Preferred Securities.
    
 
   
     Any required approval or direction of holders of Series A Preferred
Securities may be given at a separate meeting of holders of Series A Preferred
Securities convened for such purpose, at a meeting of all of the holders of
Preferred Securities of the Trust or pursuant to written consent. The Regular
Trustees will cause a notice of any meeting at which holders of Series A
Preferred Securities are entitled to vote, or of any matter
    
 
                                       81
<PAGE>   83
 
upon which action by written consent of such holders is to be taken, to be
mailed to each holder of record of Series A Preferred Securities. Each such
notice will include a statement setting forth (i) the date of such meeting or
the date by which such action is to be taken, (ii) a description of any
resolution proposed for adoption at such meeting on which such holders are
entitled to vote or of such matter upon which written consent is sought and
(iii) instructions for the delivery of proxies or consents.
 
     No vote or consent of the holders of Series A Preferred Securities will be
required for the Trust to redeem and cancel Preferred Securities of any series.
 
     Notwithstanding that holders of Series A Preferred Securities are entitled
to vote or consent under any of the circumstances described above, any of the
Series A Preferred Securities at such time that are owned by the Company, the
Operating Partnership or by any entity directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or the
Operating Partnership shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if they were not outstanding.
 
     The procedures by which persons owning Series A Preferred Securities
registered in the name of and held by DTC or its nominee may exercise their
voting rights are described under "-- Book-Entry Only Issuance -- The Depository
Trust Company" below.
 
     Subject to the right of holders of Series A Preferred Securities to appoint
a Special Regular Trustee upon the occurrence of an Appointment Event, holders
of the Series A Preferred Securities will have no rights to increase or decrease
the number of Trustees or to appoint, remove or replace a Trustee, which rights
are vested exclusively in the holders of the Common Securities.
 
CONVERSION RIGHTS
 
     Except as otherwise provided under "-- Restrictions on Ownership and
Transfer of Series A Preferred Securities," the Series A Preferred Securities
are not convertible into or exchangeable or exercisable for any other property
or securities of the Trust, the Company or the Operating Partnership.
 
MODIFICATION AND AMENDMENT OF THE DECLARATION
 
   
     The Declaration may be modified and amended by a majority of the Regular
Trustees, provided, that, (i) if any proposed modification or amendment provides
for, or the Regular Trustees otherwise propose to effect, (A) any action that
would materially and adversely affect the powers, preferences, privileges or
special rights of any series of the Preferred Securities, whether by way of
amendment to the Declaration or otherwise, or (B) the dissolution, liquidation,
winding-up or termination of the Trust other than pursuant to the terms of the
Declaration, then, subject to the terms of any such series of Preferred
Securities, the holders of each affected series of outstanding Preferred
Securities will be entitled to vote on such amendment, modification or proposal
and such amendment, modification or proposal shall not be effective with respect
to such an affected series except with the approval of at least 66 2/3% in
liquidation amount of such series.
    
 
   
     Notwithstanding any other provision in the Declaration, in the event the
holders of Series A Preferred Securities have the right to vote with respect to
a matter pursuant to the Declaration which voting right arises out of, or is
substantially similar to, a matter arising under the Partnership Agreement on
which the Property Trustee is required to obtain the direction of holders of
Series A Preferred Securities as described under "Voting Rights" above, then, to
the extent permitted by applicable law, no separate vote pursuant to the
Declaration shall be required and the vote obtained in connection with the
Property Trustee seeking the direction of holders of the Series A Preferred
Securities shall constitute complete and sufficient action with respect to such
matter under the Declaration.
    
 
   
     Notwithstanding the foregoing, (i) no amendment or modification may be made
to the Declaration unless the Regular Trustees shall have obtained (A) subject
to certain exceptions, either a ruling from the Internal Revenue Service or a
written unqualified opinion of nationally recognized independent tax counsel
experienced in such matters to the effect that the Trust will continue to be
treated as a REIT for purposes of United States federal income taxation and (B)
a written unqualified opinion of nationally recognized independent counsel
experienced in such matters to the effect that such amendment or modification
will not
    
 
                                       82
<PAGE>   84
 
   
cause the Trust to be an investment company which is required to be registered
under the 1940 Act; (ii) certain specified provisions of the Declaration may not
be amended without the consent of all of the holders of the Trust Securities,
(iii) no amendment which adversely affects the rights, powers and privileges of
the Property Trustee shall be made without the consent of the Property Trustee,
(iv) the Article of the Declaration relating to the obligation of the Company
and certain members of management of the Company to purchase the Common
Securities may not be amended without the consent of the Company, and the
Article of the Declaration relating to the restriction on the transfer of Common
Securities shall not be amended without the consent of the holders of all Common
Securities, (v) the Article of the Declaration relating to the obligation of the
Operating Partnership to pay certain obligations and expenses of the Trust as
described under "IAC Capital Trust" may not be amended without the consent of
the Operating Partnership, (vi) the rights of holders of Common Securities under
the Declaration to increase or decrease the number of, and to appoint, replace
or remove, Trustees (other than a Special Regular Trustee) shall not be amended
without the consent of all holders of Common Securities, (vii) the rights of
holders of Series A Preferred Securities under the Declaration to appoint or
remove a Special Regular Trustee shall not be amended without the consent of
each holder of Series A Preferred Securities and (viii) the Section of the
Declaration relating to the purpose of the Trust may not be amended without the
consent of a majority in liquidation amount of each series of outstanding
Preferred Securities.
    
 
   
     The Declaration further provides that it may be amended without the consent
of the holders of the Trust Securities to (i) cure any ambiguity, (ii) correct
or supplement any provision in the Declaration that may be defective or
inconsistent with any other provision of the Declaration, (iii) to add to the
covenants, restrictions or obligations of the Company or the Operating
Partnership, and (iv) to conform to changes in, or a change in interpretation or
application of certain 1940 Act requirements by the Commission, which amendment
does not materially and adversely affect the rights, preferences or privileges
of the holders of Preferred Securities.
    
 
BOOK-ENTRY ONLY ISSUANCE -- THE DEPOSITORY TRUST COMPANY
 
     DTC will act as securities depositary for the Series A Preferred
Securities. The Series A Preferred Securities will be issued only as fully
registered securities registered in the name of DTC or its nominee. One or more
fully-registered global Series A Preferred Securities certificates (each a
"Series A Preferred Securities Global Certificate"), representing the total
aggregate number of Series A Preferred Securities, will be issued and will be
deposited with DTC.
 
     The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of securities in definitive form. Such laws
may impair the ability to transfer beneficial interests in a global Series A
Preferred Security.
 
     DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its participants ("Participants") deposit with DTC. DTC
also facilitates the settlement among Participants of securities transactions,
such as transfers and pledges, in deposited securities through electronic
computerized book-entry changes in Participants' accounts, thereby eliminating
the need for physical movement of securities certificates. Direct Participants
include securities brokers and dealers, banks, trust companies, clearing
corporations, and certain other organizations ("Direct Participants"). DTC is
owned by a number of its Direct Participants and by the NYSE, the American Stock
Exchange, Inc., and the National Association of Securities Dealers, Inc. Access
to the DTC system is also available to others such as securities brokers and
dealers, banks and trust companies that clear through or maintain a custodial
relationship with a Direct Participant, either directly or indirectly ("Indirect
Participants"). The rules applicable to DTC and its Participants are on file
with the Securities and Exchange Commission.
 
     Upon issuance of a Series A Preferred Securities Global Certificate, DTC
will credit on its book-entry registration and transfer system the number of
Series A Preferred Securities represented by such Series A Preferred Securities
Global Certificate to the accounts of institutions that have accounts with DTC.
 
                                       83
<PAGE>   85
 
Ownership of beneficial interests in a Series A Preferred Securities Global
Certificate will be limited to Participants or persons that may hold interests
through Participants. The ownership interest of each actual purchaser of each
Preferred Security ("Beneficial Owner") is in turn to be recorded on the Direct
and Indirect Participants' records. Beneficial Owners will not receive written
confirmation from DTC of their purchases, but Beneficial Owners are expected to
receive written confirmations providing details of the transactions, as well as
periodic statements of their holdings, from the Direct or Indirect Participants
through which the Beneficial Owners purchased Series A Preferred Securities.
Transfers of ownership interests in the Series A Preferred Securities are to be
accomplished by entries made on the books of Participants acting on behalf of
Beneficial Owners.
 
     DTC has no knowledge of the actual Beneficial Owners of the Series A
Preferred Securities; DTC's records reflect only the identity of the Direct
Participants to whose accounts such Series A Preferred Securities are credited,
which may or may not be the Beneficial Owners. The Participants will remain
responsible for keeping account of their holdings on behalf of their customers.
So long as DTC, or its nominee, is the owner of a Series A Preferred Securities
Global Certificate, DTC or such nominee, as the case may be, will be considered
the sole owner and holder of record of the Series A Preferred Securities
represented by such Series A Preferred Securities Global Certificate for all
purposes.
 
     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     Redemption notices shall be sent to Cede & Co. If less than all of the
Series A Preferred Securities are being redeemed, DTC will reduce the amount of
interest of each Direct Participant in the Series A Preferred Securities in
accordance with its procedures.
 
     Although voting with respect to the Series A Preferred Securities is
limited, in those instances in which a vote is required, neither DTC nor Cede &
Co. itself will consent or vote with respect to the Series A Preferred
Securities. Under its usual procedures, DTC would mail an Omnibus Proxy to the
Trust as soon as possible after the record date. The Omnibus Proxy assigns Cede
& Co.'s consenting or voting rights to those Direct Participants to whose
accounts the Series A Preferred Securities are credited on the record date
(identified in a listing attached to the Omnibus proxy).
 
     Distribution payments on the Series A Preferred Securities represented by a
Preferred Series Global Certificate will be made by the Property Trustee to DTC.
DTC's practice is to credit Direct Participants' accounts on the relevant
payment date in accordance with their respective holdings shown on DTC's records
unless DTC has reason to believe that it will not receive payments on such
payment date. Payments by Participants to Beneficial Owners will be governed by
standing instructions and customary practices and will be the responsibility of
such Participants and not of DTC, the Trust or the Operating Partnership,
subject to any statutory or regulatory requirements as may be in effect from
time to time. Payment of distributions to DTC is the responsibility of the
Trust, disbursement of such payments to Direct Participants is the
responsibility of DTC, and disbursement of such payments to the Beneficial
Owners is the responsibility of Direct and Indirect Participants.
 
     Except as provided herein, a Beneficial Owner in a global Series A
Preferred Security certificate will not be entitled to receive physical delivery
of Series A Preferred Securities. Accordingly, each Beneficial Owner must rely
on the procedures of DTC to exercise any rights under the Series A Preferred
Securities.
 
     DTC may discontinue providing its services as securities depository with
respect to the Series A Preferred Securities at any time by giving reasonable
notice to the Trust. Under such circumstances, if a successor securities
depository is not obtained, Series A Preferred Security certificates will be
required to be printed and delivered. Additionally, the Trust may decide to
discontinue use of the system of book-entry transfers through DTC (or a
successor depository). In that event, certificates for the Series A Preferred
Securities will be printed and delivered.

     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Trust and the Operating Partnership
believe to be reliable. Neither the Trust nor the Operating Partnership has any
responsibility for the performance by DTC or its Participants of their
respective obligations as described hereunder or under the rules and procedures
governing their respective operations.
 
REGISTRAR, TRANSFER AGENT AND PAYING AGENT
 
     In the event the Series A Preferred Securities do not remain in book-entry
only form, the following provisions will apply:
 
     Payment of distributions and payments on redemption of the Series A
Preferred Securities will be payable, the transfer of the Series A Preferred
Securities will be registrable, and Series A Preferred Securities will be
exchangeable for Series A Preferred Securities of other denominations of a like
aggregate liquidation amount, at the principal corporate trust office of the
Property Trustee in The City of New York; provided that payment of distributions
may be made at the option of the Regular Trustees on behalf of the Trust by
check mailed to the address of the persons entitled thereto and that the payment
on redemption of any Series A Preferred Security will be made only upon
surrender of such Series A Preferred Security to the Property Trustee.
 
     The Bank of New York or one of its affiliates will act as registrar and
transfer agent for the Series A Preferred Securities. The Bank of New York will
also act as paying agent and, with the consent of the Regular Trustees, may
designate additional paying agents.
 
     Registration of transfers of Series A Preferred Securities will be effected
without charge by or on behalf of the Trust, but upon payment (with the giving
of such indemnity as the Trust or the Operating Partnership may require) in
respect of any tax or other governmental charges that may be imposed in relation
to it.
 
     In the event of any redemption in part, the Trust shall not be required to
(i) issue, register the transfer of or exchange any Series A Preferred
Securities during a period beginning at the opening of business 15 days before
any selection for redemption of Series A Preferred Securities and ending at the
close of business on the earliest date on which the relevant notice of
redemption is deemed to have been given to all holders of Series A Preferred
Securities to be redeemed and (ii) register the transfer of or exchange any
Series A Preferred Securities so selected for redemption, in whole or in part,
except the unredeemed portion of any Series A Preferred Securities being
redeemed in part. Holders of Series A Preferred Securities to be redeemed shall
surrender such Series A Preferred Securities at the place designated in the
notice of redemption and shall be entitled to the redemption price and any
accumulated and unpaid distributions payable upon such redemption following such
surrender.
 
   
     Upon presentation of any Certificate for Series A Preferred Securities
redeemed in part only, the Trust shall execute and deliver, at the expense of
the Trust, a new Certificate equal to the unredeemed portion of the Certificate
so presented.
    
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
     The Property Trustee undertakes to perform only such duties as are
specifically set forth in the Declaration and shall exercise the same degree of
care as a prudent individual would exercise in the conduct of his or her own
affairs. Subject to such provision, the Property Trustee is under no obligation
to exercise any of the powers vested in it by the Declaration at the request of
any holder of Preferred Securities, unless offered reasonable indemnity by such
holder against the costs, expenses and liabilities which might be incurred
thereby. The Property Trustee is not required to expend or risk its own funds or
otherwise incur personal financial liability in the performance of its duties if
the Property Trustee reasonably believes that repayment or adequate indemnity is
not reasonably assured to it.
 
     The Company, the Operating Partnership and certain of their affiliates may
maintain a deposit account and banking relationship with the Property Trustee.

GOVERNING LAW
 
     The Declaration and the Trust Securities will be governed by, and construed
in accordance with, the internal laws of the State of Delaware.
 
MISCELLANEOUS
 
   
     The Regular Trustees are authorized and directed to take such action as
they deem reasonable in order that the Trust (i) will not be deemed to be an
"investment company" required to be registered under the 1940 Act and (ii) that
the Trust will be classified for United States federal income tax purposes as a
REIT. In this connection, the Regular Trustees are authorized to take any
action, not inconsistent with applicable law, the certificate of trust or the
Declaration, that the Regular Trustees determine in their discretion to be
reasonable and necessary or desirable for such purposes, as long as such action
does not materially and adversely affect the interests of holders of the Trust
Securities.

                DESCRIPTION OF THE SERIES A PREFERRED L.P. UNITS
 
     The Series A Preferred L.P. Units will be issued pursuant to the
Partnership Agreement. The following summarizes the material terms and
provisions of the Series A Preferred L.P. Units and is qualified in its entirety
by reference to the Partnership Agreement, which has been filed as an exhibit to
the registration statement of which this Prospectus forms a part.
 
GENERAL
 
   
     The Operating Partnership is authorized to issue Preferred L.P. Units in
one or more series. The General Partner has the authority to establish the terms
of each series, including the preferences, conversion, and other rights, voting
powers, restrictions, limitations as to distributions, qualifications, and terms
and conditions of redemption, if any, by amending the Partnership Agreement.
Such an amendment does not require any vote or action by the holders of L.P.
Units, except as provided under applicable law.
    
 
   
     The Partnership Agreement does not contain any limitation on the number of
Preferred L.P. Units that may be issued or on the number of series that may be
established.
    
 
RANKING
 
   
     The Series A Preferred L.P. Units will, with respect to distributions and
rights upon liquidation, dissolution, winding-up or termination of the Operating
Partnership, rank (i) senior to the G.P. Units and the Common L.P. Units and
(ii) on a parity with all other series of Preferred L.P. Units issued by the
Operating Partnership unless the terms of such other series specifically provide
that such series ranks junior to the Series A Preferred L.P. Units.
    
 
DISTRIBUTIONS
 
   
     Subject to the rights of holders of other series of Preferred L.P. Units
ranking on a parity with the Series A Preferred L.P. Units as to the payment of
distributions, the Trust, as the holder of the Series A Preferred L.P. Units,
will be entitled to receive, when, as and if declared by the Operating
Partnership, acting through the Company as the sole general partner of the
Operating Partnership, out of funds legally available for the payment of
distributions, cumulative preferential cash distributions at the rate per annum
of   % of the stated value of $25 per Series A Preferred L.P. Unit.
Distributions will be cumulative, will accrue from the original date of issuance
and will be payable quarterly in arrears, on                ,                ,
               and                of each year (each a "Series A Preferred L.P.
Unit Distribution Payment Date"), commencing on                , 1998. The
amount of distributions payable for any period will be computed on the basis of
a 360-day year of twelve 30-day months and for any period shorter than a full
quarterly period for which distributions are computed, the amount of the
distribution payable will be computed on the basis of the actual number of days
elapsed in such a 30-day month. If any date on which distributions are to be
made on the Series A Preferred L.P. Units is not a Business Day, then payment of
the distribution to be made on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay) except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on such date.
Distributions on the Series A Preferred L.P. Units will be made to the Property
Trustee as the holder of record of the Series A Preferred L.P. Units.
    
 
     No distributions on the Series A Preferred L.P. Units shall be declared or
paid or set apart for payment by the Operating Partnership at such time as the
terms and provisions of any agreement of the Operating Partnership, including
any agreement relating to its indebtedness, prohibits such declaration, payment
or setting apart for payment or provides that such declaration, payment or
setting apart for payment would constitute a breach thereof or a default
thereunder, or if such declaration or payment shall be restricted or prohibited
by law. The Credit Facility provides that the Operating Partnership may make
distributions to its partners to the extent necessary to enable the Company to
make dividend payments to its shareholders as required for the Company to
maintain its status as a REIT under the Code.
 
                                       87
<PAGE>   89
 
   
     Distributions on the Series A Preferred L.P. Units will accrue regardless
of whether or not the Operating Partnership has earnings, whether or not there
are funds legally available for the payment of such distributions, and whether
or not such distributions are declared and will accumulate to the extent that
they are not paid as of the Series A Preferred L.P. Unit Distribution Payment
Date on which they first become payable. Accumulated and unpaid distributions
will not bear interest. So long as any Series A Preferred L.P. Units are
outstanding, no distribution shall be paid or declared on or with respect to the
Common L.P. Units or the G.P. Units or any other series of outstanding Preferred
L.P. Units ranking junior as to the payment of distributions to the Series A
Preferred L.P. Units (collectively, "Junior OP Units"), nor shall any sum or
sums be set aside for or applied to the purchase or redemption of the Series A
Preferred L.P. Units or any other series of outstanding Preferred L.P. Units or
the purchase, redemption or other acquisition for value of any Junior OP Units
unless, in each case, full cumulative distributions accumulated on all Series A
Preferred L.P. Units and all other series of outstanding Preferred L.P. Units
ranking on a parity with the Series A Preferred L.P. Units as to the payment of
distributions have been paid in full, provided that the foregoing will not
prohibit distributions payable solely in Junior OP Units, the exchange of Common
L.P. Units for Common Stock of the Company in accordance with the Exchange
Rights set forth in the Partnership Agreement, the repurchase of Common L.P.
Units in connection with the exercise by the holders thereof of the Cash Tender
Rights set forth in the Partnership Agreement, the exchange of Common L.P. Units
for G.P. Units as provided in the Partnership Agreement or the repayment,
return, forfeiture and cancellation of Common L.P. Units issued in connection
with land acquisitions by the Operating Partnership as and to the extent
provided pursuant to the purchase agreement relating to any such acquisition.
When distributions have not been paid in full upon the Series A Preferred L.P.
Units on the applicable Preferred L.P. Unit Distribution Payment Date (or a sum
sufficient for such full payment is not set apart therefor), all distributions
declared and paid on the Series A Preferred L.P. Units and any other series of
outstanding Preferred L.P. Units ranking on a parity with the Series A Preferred
L.P. Units as to the payment of distributions shall be declared and paid so that
the amount of distributions declared and paid on the Series A Preferred L.P.
Units and such other series of Preferred L.P. Units shall in all cases bear to
each other the same ratio that the respective distribution rights of the Series
A Preferred L.P. Units and such other series of Preferred L.P. Units (which
shall not include any accumulation in respect of unpaid distributions for prior
distribution periods if such other series of Preferred L.P. Units do not have
cumulative distribution rights) bear to each other. Holders of Series A
Preferred L.P. Units shall not be entitled to any distributions, whether payable
in cash, property or otherwise, in excess of the full cumulative distributions
described herein.
    
 
LIQUIDATION
 
   
     Subject to the rights of holders of any other series of Preferred L.P.
Units ranking on a parity with the Series A Preferred L.P. Units, upon any
voluntary or involuntary dissolution, liquidation, winding-up or termination of
the Operating Partnership, the holders of the Series A Preferred L.P. Units will
be entitled to receive out of the assets of the Operating Partnership legally
available for distribution, after payment or provision for payment of debts and
other liabilities of the Operating Partnership an amount equal to the stated
value of $25 per Series A Preferred L.P. Unit, plus accumulated and unpaid
distributions thereon to the date of payment and no more. If upon any such
liquidation, dissolution, winding-up or termination, there are insufficient
assets to permit full payment to the holders of Series A Preferred L.P. Units
and any other series of outstanding Preferred L.P. Units ranking on a parity
upon liquidation, dissolution, winding-up or termination of the Operating
Partnership with the Series A Preferred L.P. Units, the holders of Series A
Preferred L.P. Units and such other series of Preferred L.P. Units shall be paid
ratably in proportion to the full distributable amount to which holders of
Series A Preferred L.P. Units and such other series of Preferred L.P. Units are
respectively entitled upon liquidation, dissolution, winding-up or termination.
The full preferential amount payable to holders of the Series A Preferred L.P.
Units and such other series of outstanding Preferred L.P. Units upon any such
liquidation, dissolution, winding-up or termination will be paid in full before
any distribution or payment is made to the holders of Common L.P. Units, G.P.
Units or any other series of outstanding Preferred L.P. Units ranking junior to
the Series A Preferred L.P. Units on liquidation, dissolution, winding-up or
termination of the Operating Partnership. The consolidation or merger of the
Operating Partnership with or into any corporation, trust, or other entity (or
of any corporation, trust or entity
    
 
                                       88
<PAGE>   90
 
   
with or into the Operating Partnership) shall not be deemed to constitute a
liquidation, dissolution, winding-up or termination of the Operating
Partnership.
    
 
REDEMPTION
 
   
     Except in the case of a Special Event, the Series A Preferred L.P. Units
may not be redeemed prior to                . On or after such date, the
Operating Partnership shall have the right to redeem the Series A Preferred L.P.
Units, in whole or in part, from time to time, upon not less than 30 nor more
than 60 days' notice, at a redemption price equal to $25 per Series A Preferred
L.P. Unit plus accumulated and unpaid distributions to the date of payment.
Except in connection with a dissolution, liquidation, winding-up or termination
of the Operating Partnership as described under "Liquidation" above, the
redemption price of the Series A Preferred L.P. Units (other than the portion
thereof consisting of accumulated but unpaid distributions) is payable solely
out of the sale proceeds of capital stock of the Company, which will be
contributed by the Company to the Operating Partnership as an additional capital
contribution, or L.P. Units of the Operating Partnership and from no other
source. Unless previously redeemed, the Series A Preferred L.P. Units will be
redeemed for cash upon termination of the Operating Partnership. Unless sooner
dissolved, the Operating Partnership will terminate on December 31, 2092, which
is the stated maturity date of the Series A Preferred L.P. Units.
    
 
     If, at any time, a Tax Event or Investment Company Event or (each, a
"Special Event") shall occur and be continuing, the Operating Partnership shall
have the right to redeem the Series A Preferred L.P. Units in whole but not in
part, as set forth below, provided, however, that, if at the time there is
available to the Operating Partnership or the Trust the opportunity to
eliminate, within a 90-day period, the Special Event by taking some ministerial
action (collectively, "Ministerial Actions"), such as filing a form or making an
election, or pursuing some other similar reasonable measure, which in the sole
judgment of the Company, as general partner of the Operating Partnership, has or
will cause no adverse effect on the Trust, the Operating Partnership, the
Company or the holders of the Preferred Securities and will involve no material
cost, the Operating Partnership and the Trust will pursue such measure in lieu
of such redemption, provided further that the Operating Partnership shall have
no right to redeem the Series A Preferred L.P. Units while the Operating
Partnership or the Regular Trustees on behalf of the Trust are pursuing any such
Ministerial Action. The Operating Partnership shall have the right, upon not
less than 30 nor more than 60 days' notice, to redeem the Series A Preferred
L.P. Units in whole for cash as provided in the preceding paragraph within 90
days following the occurrence of such Special Event (subject to extension for
the number of days Ministerial Actions are pursued).
 
     "Investment Company Event" means that the Operating Partnership and the
Regular Trustees shall have received an opinion of nationally recognized
independent counsel experienced in practice under the 1940 Act, that as a result
of the occurrence of a change in law or regulation or a change in interpretation
or application of law or regulation by any legislative body, court, governmental
agency or regulatory authority (a "Change in 1940 Act Law"), there is more than
an insubstantial risk that the Trust is or will be considered an "investment
company" which is required to be registered under the 1940 Act, which Change in
1940 Act Law becomes effective on or after the date of this Prospectus.
 
   
     "Tax Event" means that the Operating Partnership and the Regular Trustees
shall have received an opinion of nationally recognized independent tax counsel
experienced in such matters that there is more than an insubstantial risk that
the Trust does not qualify, or within 90 days of the date of such opinion will
no longer qualify, as a REIT under the Code for any reason whatsoever, provided
that a Tax Event shall not include the voluntary election by the Regular
Trustees and/or the holders of the Common Securities to terminate the Trust's
status as a real estate investment trust for federal income tax purposes.
    
 
     If the Operating Partnership gives a notice of redemption in respect of
Series A Preferred L.P. Units (which notice will be irrevocable) then, by 12:00
noon, New York City time, on the redemption date, the Operating Partnership will
deposit irrevocably in trust for the benefit of the Series A Preferred L.P.
Units being redeemed funds sufficient to pay the applicable redemption price and
will give irrevocable instructions and authority to pay such redemption price to
the holders of the Series A Preferred L.P. Units. If notice of
 
                                       89
<PAGE>   91
 
   
redemption shall have been given and funds deposited as required, then upon the
date of such deposit, distributions will cease to accumulate on the Series A
Preferred L.P. Units called for redemption, such Series A Preferred L.P. Units
will no longer be deemed to be outstanding and all rights of holders of such
Series A Preferred L.P. Units so called for redemption will cease, except the
right of the holders of such Series A Preferred L.P. Units to receive the
applicable redemption price, but without interest on such redemption price. If
any date fixed for redemption of Series A Preferred L.P. Units is not a Business
Day, then payment of the redemption price payable on such date will be made on
the next succeeding day that is a Business Day (and without any interest or
other payment in respect of any such delay) except that, if such Business Day
falls in the next calendar year, such payment will be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date fixed for redemption. If payment of the redemption price in respect
of the Series A Preferred L.P. Units is improperly withheld or refused and not
paid by the Operating Partnership, distributions on such Series A Preferred L.P.
Units will continue to accumulate from the original redemption date to the date
of payment, in which case the actual payment date will be considered the date
fixed for redemption for purposes of calculating the applicable redemption
price. If fewer than all of the Series A Preferred L.P. Units are to be
redeemed, the Series A Preferred L.P. Units to be redeemed shall be selected by
lot or pro rata (as nearly as practicable without creating fractional units) or
in some other equitable manner determined by the Operating Partnership.
    
 
     In the event of any redemption in part, the Operating Partnership shall not
be required to (i) issue, register the transfer of or exchange any Series A
Preferred L.P. Units during a period beginning at the opening of business 15
days before any selection for redemption of Series A Preferred L.P. Units and
ending at the close of business on the earliest date on which the relevant
notice of redemption is deemed to have been given to all holders of Series A
Preferred L.P. Units to be redeemed and (ii) register the transfer of or
exchange any Series A Preferred L.P. Units so selected for redemption, in whole
or in part, except the unredeemed portion of any Series A Preferred L.P. Units
being redeemed in part. Holders of Series A Preferred L.P. Units to be redeemed
shall surrender such Series A Preferred L.P. Units at the place designated in
the notice of redemption and shall be entitled to the redemption price and any
accumulated and unpaid distributions payable upon such redemption following such
surrender.
 
   
     The Operating Partnership may not redeem fewer than all the outstanding
Series A Preferred L.P. Units unless all accumulated and unpaid distributions
have been paid on all Series A Preferred L.P. Units for all quarterly
distribution periods terminating on or prior to the date of redemption.
    
 
   
     Notice of redemption will be mailed by the Operating Partnership, postage
prepaid, not less than 30 nor more than 60 days prior to the redemption date,
addressed to the respective holders of record of the Series A Preferred L.P.
Units to be redeemed at their respective addresses as they appear on the
transfer records of the Operating Partnership. No failure to give or defect in
such notice shall affect the validity of the proceedings for the redemption of
any Series A Preferred L.P. Units except as to the holder to whom notice was
defective or not given. Each notice shall state: (i) the redemption date; (ii)
the redemption price; (iii) the number of Series A Preferred L.P. Units to be
redeemed; (iv) the place or places where the Series A Preferred L.P. Units is to
be surrendered for payment of the redemption price; (v) that distributions on
the Series A Preferred L.P. Units to be redeemed will cease to accumulate on
such redemption date and (vi) that payment of the redemption price will be made
upon presentation and surrender of such Series A Preferred Limited Partner
Units. If fewer than all of the Series A Preferred L.P. Units held by any holder
are to be redeemed, the notice mailed to such holder shall also specify the
number of Series A Preferred L.P. Units to be redeemed from such holder.
    
 
     The holders of Series A Preferred L.P. Units at the close of business on a
distribution record date will be entitled to receive the distribution payable
with respect to such Series A Preferred L.P. Units on the corresponding
distribution payment date notwithstanding the redemption thereof between such
distribution record date and the corresponding distribution payment date or the
Operating Partnership's default in the payment of the distribution due. Except
as provided above, the Operating Partnership will make no payment or allowance
for unpaid distributions, regardless of whether in arrears, on Series A
Preferred L.P. Units called for redemption.
 
                                       90
<PAGE>   92
 
     The Series A Preferred L.P. Units have a stated maturity of December 31,
2092, and will not be subject to any sinking fund or mandatory redemption and
will not be convertible into any other securities of the Company or the
Operating Partnership.
 
VOTING RIGHTS
 
   
     Holders of the Series A Preferred L.P. Units will not have any voting
rights, except as set forth below and as otherwise required by law and the
Partnership Agreement.
    
 
   
     If any proposed amendment or modification of the Partnership Agreement
would materially and adversely affect the powers, special rights, preferences or
privileges of the Series A Preferred L.P. Units, then the holders of outstanding
Series A Preferred L.P. Units will be entitled to vote on such amendment or
modification as a class, and such amendment or modification shall not be
effective except with the approval of the holders of at least 66 2/3% in stated
value of the outstanding Series A Preferred L.P. Units; provided, however, that
any such amendment or modification that would authorize, create or issue any
additional series of Preferred L.P. Units ranking on a parity with or junior to
the Series A Preferred L.P. Units as to distributions or upon liquidation,
dissolution, winding-up or termination of the Operating Partnership shall be
deemed not to materially and adversely effect such powers, special rights,
preferences or privileges; and, provided further, that prior to        , any
amendment or modification to the definition of Tax Event shall be deemed to
materially and adversely affect such powers, special rights, preferences and
privileges.

                 RELATIONSHIP BETWEEN THE PREFERRED SECURITIES
                          AND THE PREFERRED L.P. UNITS
 
   
     As set forth in the Declaration, the Trust exists for the sole purpose of
(a) issuing its Preferred Securities (and, if applicable, Excess Preferred
Securities), (b) issuing its Common Securities as described herein and investing
the proceeds of such issuance in an interest bearing account at, or a
certificate of, a bank, (c) investing the proceeds from the sale of each series
of Preferred Securities in a series of Preferred L.P. Units of the Operating
Partnership and (d) engaging in such other activities as are necessary,
convenient or incidental thereto.
    
 
   
     The Trust's ability to make distributions and other payments on the Series
A Preferred Securities is initially effectively dependent upon the Operating
Partnership making distributions and other payments on the Series A Preferred
L.P. Units held as trust assets. If the Operating Partnership does not make
distributions or other payments on the Preferred L.P. Units for any reason, it
is expected that the Trust will not be able to make payments on the Series A
Preferred Securities.
    
 
   
     Initially, as long as distributions and other payments are made on the
Series A Preferred L.P. Units, such payments will be sufficient to cover
distributions and other payments due on the Series A Preferred Securities
primarily because (i) the aggregate stated value of Series A Preferred L.P.
Units held as trust assets will be equal to the aggregate liquidation amount of
the Series A Preferred Securities; (ii) the distribution rate and distribution
and other payment dates on the Series A Preferred L.P. Units will match the
distribution rate and distribution and other payment dates on the Series A
Preferred Securities; (iii) the Declaration provides that the Operating
Partnership shall reimburse all costs, expenses and liabilities of the Trust,
including any taxes and all costs and expenses with respect thereto, to which
the Trust may become subject, except with respect to distributions on the Trust
Securities and withholding taxes on such distributions; and (iv) the Declaration
further provides that the Trustees shall not cause or permit the Trust, among
other things, to engage in any activity that is not consistent with the limited
purposes of the Trust. With respect to clause (iii) above, however, no assurance
can be given that the Operating Partnership will have sufficient resources to
enable it to pay such costs, expenses and liabilities on behalf of the Trust.
    
 
   
     The Property Trustee will have the power to exercise all rights, powers and
privileges under the Operating Partnership Limited Partnership Agreement with
respect to the Limited Partnership Units of the Operating Partnership held by
the Trust. In addition, the holders of at least a majority in liquidation amount
of the Preferred Securities will have the right to direct the Property Trustee
with respect to taking certain legal actions under the Declaration. If the
Property Trustee fails to enforce its rights under the Operating Partnership
Limited Partnership Agreement, any holder of Preferred Securities may institute
a legal proceeding against the Operating Partnership to enforce such rights. See
"Description of the Series A Preferred Securities."

                        OPERATING PARTNERSHIP AGREEMENT
 
     The following summary of certain provisions of the Partnership Agreement,
including the descriptions of certain provisions set forth elsewhere in this
Prospectus, is qualified in its entirety by reference to the Partnership
Agreement, which is filed as an exhibit to the Registration Statement of which
this Prospectus forms a part.
 
MANAGEMENT
 
     The Operating Partnership is organized as a Delaware limited partnership
pursuant to the terms of the Partnership Agreement. Generally, pursuant to the
Partnership Agreement, the Company, as the sole general partner of the Operating
Partnership, will have full, exclusive and complete responsibility and
discretion in the management, operation and control of the Operating
Partnership, including the ability to cause the Operating Partnership to enter
into certain major transactions including acquisitions, refinancings and the
selection of property managers and any changes in the Operating Partnership's
distribution policies. The Board of Directors of the Company will manage the
affairs of the Operating Partnership. The Irvine Company has the right to
nominate three persons for election to the Board of Directors so long as The
Irvine Company, its stockholders or its affiliates beneficially own at least 20%
of the outstanding shares of Common Stock (including for these purposes shares
issuable upon exercise of Exchange Rights set forth in the Partnership Agreement
subject to the ownership limit provision of the Company's Articles of
Incorporation applicable to The Irvine Company). In the event that this
ownership falls below 20% but is at least 15%, The Irvine Company will have the
right to nominate two persons for election to the Board of Directors; and if
this ownership falls below 15% but is at least 10%, The Irvine Company will have
the right to nominate one person for election to the Board of Directors.
Dispositions of properties are subject to the condition that there will be
sufficient cash distributed to partners of the Operating Partnership to allow,
subject to certain limitations, all such partners (including the Company) to pay
may tax liabilities arising from the disposition and on the distribution itself.
 
     The consent of a majority of the outstanding Common L.P. Units will be
required with respect to certain extraordinary actions involving the Operating
Partnership including (i) the amendment, modification or termination of the
Partnership Agreement, (ii) a general assignment for the benefit of creditors or
the appointment of a custodian, receiver or trustee for any of the assets of the
Operating Partnership, (iii) the institution of any proceeding for bankruptcy of
the Operating Partnership, (iv) the transfer of any general partnership interest
in the Operating Partnership, including through any merger, consolidation or
liquidation of the Company, subject to certain exceptions, (v) the admission of
any additional or substitute general partner in the Operating Partnership; (vi)
for the Company to take title to assets (other than temporarily in connection
with an acquisition prior to contributing such assets to the Operating
Partnership) or to conduct business other than through the Operating
Partnership; and (vii) for the Company or the Operating Partnership to engage in
any business other than the ownership, construction, development and operation
of apartment communities. The Partnership Agreement requires, absent receipt of
consent, that title to assets be in the Operating Partnership in order to
maintain a one-for-one exchange ratio between Common L.P. Units and shares of
Common Stock. If such consent is obtained, the Company and The Irvine Company
agree to negotiate in good faith to amend the Partnership Agreement, including
the mechanics for calculating the exchange ratio, in order to reflect such
direct ownership of assets by the Company.
 
     In addition, until such time as the Company owns 90% or more of the total
Common L.P. Units in the Operating Partnership, the consent of the limited
partners holding a majority interest in the Common L.P. Units will also be
required with respect to the liquidation of the Operating Partnership, the sale
or other transfer of all or substantially all of the assets of the Operating
Partnership and certain mergers and business combinations resulting in the
complete disposition of all Common L.P. Units.
 
     Holders of Preferred L.P. Units will have no voting rights except as
described under "Description of the Series A Preferred L.P. Units -- Voting
Rights."
 
     The Company has unilateral control over the Operating Partnership but The
Irvine Company and its nominees to the Company's Board of Directors will have
substantial influence over the affairs of the Company
 
                                       93
<PAGE>   95
 
and thus the Operating Partnership. The Partnership Agreement prohibits the
Operating Partnership from lending money to any Irvine Person.
 
TRANSFER OF L.P. UNITS
 
   
     The Preferred L.P. Units held by the Trust as trust assets may not be
transferred except to a successor entity as provided under "Description of the
Series A Preferred Securities -- Merger, Consolidation or Amalgamation of the
Trust."
    
 
     The Partnership Agreement provides that limited partners may transfer their
Common L.P. Units subject to certain limitations. Other than transfers to or
among The Irvine Company or affiliates of The Irvine Company, transfers
resulting from a dividend or other distribution by The Irvine Company to its
stockholders or pledges securing loans made by financial institutions, holders
of Common L.P. Units may only transfer their Common L.P. Units to a purchaser
who is an accredited investor within the meaning of Regulation D under the
Securities Act.
 
     In addition, no transfer of Common L.P. Units by the limited partners may
be made in violation of certain regulatory and other restrictions set forth in
the Partnership Agreement. Any other transfers may be made only with the prior
written consent of the Company as the sole general partner of the Operating
Partnership. Other than with respect to transfers to or among The Irvine Company
or affiliates of The Irvine Company, transfers resulting from a dividend or
other distribution by The Irvine Company to its stockholders or pledges securing
loans made by financial institutions, the Exchange Rights and the Cash Tender
Rights will no longer be applicable to Common L.P. Units so transferred and the
transferee will not have any rights to nominate persons to the Board of
Directors of the Company.
 
ISSUANCE OF ADDITIONAL L.P. UNITS
 
   
     As general partner of the Operating Partnership, the Company has the
ability to cause the Operating Partnership to issue additional G.P. Units and
L.P. Units in the Operating Partnership. In addition, in the event of the
exercise of an option or the delivery of stock pursuant to the 1993 Stock Plan,
the 1996 Stock Plan, the 1993 Stock Plan for Directors and the Company's
Dividend Reinvestment and Additional Cash Investment Plan, the Operating
Partnership will issue additional G.P. Units to the Company. See "Policies With
Respect to Certain Activities -- Operating Partnership -- Financing Policies"
for certain participation rights granted to The Irvine Company in connection
with issuances of L.P. Units.
    
 
EXCHANGE RIGHTS
 
     The Irvine Company and certain related persons have the right (subject to
the ownership limit provision of the Company's Articles of Incorporation
applicable to The Irvine Company), exercisable once in each twelve-month period,
to exchange up to one-third of the number of Common L.P. Units owned by them for
shares of Common Stock or if The Irvine Company and certain related persons own
6,149,000 Common L.P. Units or less, then they may, subject to such ownership
limit provision, exchange all of their Common L.P. Units for shares of Common
Stock. As of October 31, 1997, The Irvine Company and its affiliates owned
24,199,080 Common L.P. Units in the aggregate. The exchange ratio is one share
of Common Stock for each Common L.P. Unit, subject to adjustment in certain
events, including the Company paying a dividend or making a distribution on the
Common Stock in shares of Common Stock and subdivisions and combinations of the
Common Stock. Common L.P. Units that are acquired by the Company pursuant to the
exercise of Exchange Rights will be converted automatically into G.P. Units in
the Operating Partnership.
 
     The exercise of Exchange Rights is subject to (i) the expiration or
termination of the applicable waiting period, if any, under the
Hart-Scott-Rodino Antitrust Improvement Act of 1976, and (ii) the satisfaction
of the applicable ownership limit provision of the Articles of Incorporation,
after giving effect to the exchange. For purposes of determining the number of
Common L.P. Units which may be exchanged for shares of Common Stock pursuant to
the Exchange Rights at any point in time, there shall be taken into account the
number of issued and outstanding shares of Common Stock which are beneficially
owned by The Irvine Company and its affiliates at such time. Accordingly,
beneficial ownership by The Irvine Company and its
 
                                       94
<PAGE>   96
 
affiliates of shares of Common Stock reduces the number of Common L.P. Units
which may be exchanged pursuant to the Exchange Rights at any point in time.
 
CASH TENDER RIGHTS
 
     The Irvine Company and certain related persons have the right, exercisable
once in any twelve-month period, subject to certain limitations, to sell to the
Company for cash up to one-third of the number of Common L.P. Units owned by
them or if The Irvine Company and certain related persons own 6,149,000 Common
L.P. Units or less, then they may tender all of their Common L.P. Units to the
Company. Common L.P. Units that are acquired by the Company as a result of the
exercise of Cash Tender Rights will be converted automatically into G.P. Units
in the Operating Partnership.
 
     The Company will have to pay for such Common L.P. Units solely out of the
proceeds of a registered offering of newly issued shares of Common Stock. The
price payable for a Common L.P. Unit tendered will be equal to the average of
the daily market prices for the Common Stock for the 10 consecutive trading days
immediately preceding the date of receipt by the Company of a notice of cash
tender (each Common L.P. Unit being equivalent to one share of Common Stock,
subject to adjustment as described above), except that the purchase price for
such Common L.P. Units will be reduced by any decrease in the price of the
Common Stock that occurs between the exercise date and the pricing of the Common
Stock being sold pursuant to the registered offering and underwriting discounts
and commissions. The Irvine Company will thus bear the risk of any such
reduction, subject to certain withdrawal rights. Any proceeds in excess of the
purchase price will be for the sole benefit of the Company. The Company shall be
required to promptly file with the Commission a registration statement with
respect to any registered offering.
 
     After an exercise of Cash Tender Rights, The Irvine Company may not
exercise its Cash Tender Rights until 90 days after the completion of the
registered offering of shares of Common Stock if applicable.
 
FUNDING OF INVESTMENTS
 
   
     The Partnership Agreement provides that if the Operating Partnership
requires additional funds to pursue its investment objectives, the Company may
fund such investments by raising additional equity capital and making a capital
contribution to the Operating Partnership or by borrowing such funds and lending
the net proceeds thereof to the Operating Partnership. If the Company funds an
investment as a contribution to capital and purchase of G.P. Units or lends
funds to the Operating Partnership, the holders of Common L.P. Units (subject to
certain minor exceptions) will have the right to participate in such funding or
loan on a pro rata basis. In the event that such holders do not participate in
such funding, the Company's interest in the Operating Partnership will be
increased based upon the amount of such additional capital contributions and the
value of the Operating Partnership at the time of such contributions. See
"Policies With Respect to Certain Activities -- Operating
Partnership -- Financing Policies." The amount of any such loan may be limited
by the requirement that the Company derive at least 75% of its gross income from
certain investments related to real property. See "Certain Federal Income Tax
Consequences."
    
 
TAX ACCOUNTING
 
     The Operating Partnership has a taxable year ending on December 31,
pursuant to a Code provision that requires a partnership to adopt the same tax
year as its majority in interests partner.
 
TERM
 
     The Operating Partnership will continue in full force and effect until
December 31, 2092 or until sooner dissolved pursuant to the terms of the
Partnership Agreement.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
    
 
   
     The following summary of material federal income tax considerations
regarding an investment in Series A Preferred Securities is based on current law
and is for general information only. See "Recent Legislation Applicable to
REITs," below, for a discussion of changes to the Code made by the Taxpayer
Relief Act of 1997. Such changes generally do not apply to the Trust until its
taxable year beginning January 1, 1998. This discussion addresses initial
holders only, and does not purport to deal with all aspects of taxation that may
be relevant to particular investors in light of their personal investment or tax
circumstances, or, except to the extent discussed under the headings "Taxation
of Tax-Exempt Holders" and "Taxation of Foreign Holders" below, to certain types
of investors (including insurance companies, tax-exempt organizations, financial
institutions or broker-dealers, foreign corporations and persons who are not
citizens or residents of the United States) that are subject to special
treatment under the federal income tax laws.
    
 
     EACH PROSPECTIVE PURCHASER IS ADVISED TO CONSULT HIS TAX ADVISOR REGARDING
THE SPECIFIC TAX CONSEQUENCES TO HIM OF THE PURCHASE, OWNERSHIP AND SALE OF
PREFERRED SECURITIES AND OF THE TRUST'S ELECTION TO BE TAXED AS A REAL ESTATE
INVESTMENT TRUST, INCLUDING THE FEDERAL, STATE, LOCAL, FOREIGN INCOME AND OTHER
TAX CONSEQUENCES OF SUCH PURCHASE, OWNERSHIP, SALE AND ELECTION.
 
TAXATION OF THE TRUST
 
   
     The REIT provisions of the Code are highly technical and complex. The
following sets forth the material aspects of the provisions of the Code that
govern the federal income tax treatment of a REIT and its beneficial owners.
This summary is qualified in its entirety by the applicable Code provisions,
rules and regulations promulgated thereunder, and administrative and judicial
interpretations thereof, all of which are subject to change which may apply
retroactively.
    
 
   
     The Trust will elect to be taxed as a REIT under the Code commencing with
its taxable year ending December 31, 1998, and the Trust intends to operate so
as to qualify as a REIT. In the opinion of Davis Polk & Wardwell, commencing
with the Trust's taxable year ending December 31, 1998, the Trust will be
treated as being organized in conformity with the requirements for qualification
as a REIT, and its proposed method of operation will enable it to meet the
requirements for qualification and taxation as a REIT under the Code. It must be
emphasized that this opinion is based and conditioned upon certain assumptions
and representations made by the Trust and the Company as to factual matters
concerning the business and properties as set forth in this Prospectus. The
opinion is expressed as of its date and Davis Polk & Wardwell has no obligation
to advise holders of Preferred Securities of any subsequent change in the
matters stated, represented or assumed or any subsequent change in the
applicable law. Moreover, qualification and taxation as a REIT depends upon the
Trust's ability to meet, through actual annual operating results, distribution
levels, diversity of ownership and various other qualification tests imposed
under the Code (as discussed below), the results of which will not be reviewed
by Davis Polk & Wardwell. Accordingly, no assurance can be given that the actual
results of the Trust's operation for any one taxable year will satisfy such
requirements. See "-- Failure to Qualify." An opinion of counsel is not binding
on the Internal Revenue Service (the "IRS"), and no assurance can be given that
the Service will not challenge the Trust's eligibility for taxation as a REIT.
    
 
     If the Trust qualifies for taxation as a REIT, it generally will not be
subject to federal corporate income tax on its net income that is currently
distributed to holders of Trust Securities. This treatment substantially
eliminates the "double taxation" (at the corporate and stockholder levels) that
generally results from investment in an entity that is taxable as a corporation.
However, the Trust will be subject to federal income tax as follows: First, the
Trust will be taxed at regular corporate rates on any undistributed REIT taxable
income, including undistributed net capital gains, if any. Second, under certain
circumstances, the Trust may be subject to the "alternative minimum tax" on its
items of tax preference. Third, if the Trust has net income from prohibited
transactions (which are, in general, certain sales or other dispositions of
property held primarily for sale to customers in the ordinary course of business
other than foreclosure property), such income will be subject to a 100% tax.
Fourth, if the Trust should fail to satisfy the 75% gross income test or the
 
                                       96
<PAGE>   98
 
95% gross income test (as discussed below), but has nonetheless maintained its
qualification as a REIT because certain other requirements have been met, it
will be subject to a 100% tax on an amount equal to (a) the gross income
attributable to the greater of the amount by which the Trust fails the 75% or
95% test multiplied by (b) a fraction intended to reflect the Trust's
profitability. Fifth, if the Trust should fail to distribute during each
calendar year at least the sum of (i) 85% of its REIT ordinary income for such
year, (ii) 95% of its REIT capital gain net income for such year, and (iii) any
undistributed taxable income from prior periods, the Trust would be subject to a
4% excise tax on the excess of such required distribution over the amounts
actually distributed. In addition, the Trust could also be subject to tax in
certain situations and on certain transactions not presently contemplated.
 
     Requirements for Qualification. The Code defines a REIT as a corporation,
trust or association (1) that is managed by one or more trustees or Directors;
(2) the beneficial ownership of which is evidenced by transferable shares, or by
transferable certificates of beneficial interest; (3) which would be taxable as
a domestic corporation, but for the special Code provisions applicable to REITs;
(4) that is neither a financial institution nor an insurance company subject to
certain provisions of the Code; (5) the beneficial ownership of which is held by
100 or more persons; (6) in which, during the last half of each taxable year,
not more than 50% in value of the outstanding stock is owned, directly or
indirectly, by five or fewer individuals (as defined in the Code to include
certain entities); and (7) which meets certain other tests described below
(including with respect to the nature of its income and assets). The Code
provides that conditions (1) to (4), inclusive, must be met during the entire
taxable year, and that condition (5) must be met during at least 335 days of a
taxable year of 12 months, or during a proportionate part of a taxable year of
less than 12 months. The Declaration provides for restrictions regarding the
transfer of Preferred Securities, which provisions are intended to assist the
Trust in continuing to satisfy the ownership requirements described in
conditions (5) and (6) above. Such transfer restrictions are described in
"Description of the Series A Preferred Securities -- Restrictions on Ownership
and Transfer of Series A Preferred Securities."
 
     To monitor the Trust's compliance with the ownership requirements, the
Trust is required to maintain records regarding the actual ownership of the
Trust Securities. To do so, the Trust must demand written statements each year
from the record holders of certain percentages of Trust Securities in which the
record holders are to disclose the actual owners of the securities (i.e., the
persons required to include in gross income the REIT dividends). A list of those
persons failing or refusing to comply with this demand must be maintained as
part of the Trust's records. A holder of Trust Securities who fails or refuses
to comply with the demand must submit a statement with its tax return disclosing
the actual ownership of the securities and certain other information.
 
     In addition, a corporation or trust may not elect to become a REIT unless
its taxable year is the calendar year. The Trust satisfies this requirement.
 
   
     Ownership of Partnership Interests. In the case of a REIT that is a partner
in a partnership, regulations provide that the REIT will be deemed to own its
proportionate share of the partnership's assets and to earn its proportionate
share of the partnership's income. In addition, the assets and gross income of
the partnership retain the same character in the hands of the REIT for purposes
of the gross income and asset tests applicable to REITs as described below.
Thus, the Trust's proportionate share of the assets, liabilities and items of
income of the Operating Partnership will be treated as assets, liabilities and
items of income of the Trust for purposes of applying the REIT requirements
described below. A summary of the rules governing the federal income taxation of
partnerships and their partners is provided below in "-- Tax Aspects of the
Trust's Investment in the Operating Partnership."
    
 
     Income Tests. In order to maintain qualification as a REIT, the Trust
annually must satisfy three gross income requirements. First, at least 75% of
the Trust's gross income (excluding gross income from "prohibited transactions,"
i.e., certain sales of property held primarily for sale to customers in the
ordinary course of business) for each taxable year must be derived directly or
indirectly from investments in real property or mortgages on real property
(including "rents from real property" and, in certain circumstances, interest)
or from certain types of temporary investments. Second, at least 95% of the
Trust's gross income (excluding gross income from prohibited transactions) for
each taxable year must be derived from such real property
 
                                       97
<PAGE>   99
 
investments, and from other dividends, interest and gain from the sale or
disposition of stock or securities (or from any combination of the foregoing).
 
     Rents received by the Trust through the Operating Partnership will qualify
as "rents from real property" in satisfying the gross income requirements
described above only if several conditions are met, including the following. If
rent attributable to personal property leased in connection with a lease of real
property is greater than 15% of the total rent received under the lease, then
the portion of rent attributable to such personal property will not qualify as
"rents from real property." Moreover, for rents received to qualify as "rents
from real property," the REIT generally must not operate or manage the property
or furnish or render services to the tenants of such property, other than
through an "independent contractor" from which the REIT derives no revenue.
However, the Trust or its affiliates are permitted to, and do directly perform
services that are "usually or customarily rendered" in connection with the
rental of space for occupancy only and are not otherwise considered rendered to
the occupant of the property.
 
   
     If the Trust fails to satisfy one or both of the 75% or 95% gross income
tests (though not the 30% gross income test) for any taxable year, it may
nevertheless qualify as a REIT for such year if it is entitled to relief under
certain provisions of the Code. These relief provisions will be generally
available if the Trust's failure to meet such tests was due to reasonable cause
and not due to willful neglect, the Trust attaches a schedule of the sources of
its income to its return, and any incorrect information on the schedule was not
due to fraud with intent to evade tax. It is not possible, however, to state
whether in all circumstances the Trust would be entitled to the benefit of these
relief provisions. If these relief provisions are inapplicable to a particular
set of circumstances involving the Trust, the Trust will not qualify as a REIT.
As discussed above, even where these relief provisions apply, a tax is imposed
with respect to the excess net income.
    
 
     Asset Tests. The Trust, at the close of each quarter of its taxable year,
must also satisfy two tests relating to the nature of its assets. First, at
least 75% of the value of the Trust's total assets must be represented by real
estate assets (including its allocable share of real estate assets held by the
Operating Partnership), stock or debt instruments held for not more than one
year purchased with the proceeds of an offering of beneficial interests of the
Trust, cash, cash items and government securities. Second, the remaining 25% of
the Trust's total assets may be invested in securities, subject to the following
restrictions: (i) the value of any one issuer's securities owned by the Trust
may not exceed 5% of the value of the Trust's total assets, and (ii) the Trust
may not own more than 10% of any one issuer's outstanding voting securities. The
Trust does not intend to invest in securities other than Preferred L.P. Units
and certain interest bearing obligations.
 
     Annual Distribution Requirements. The Trust, in order to qualify as a REIT,
is required to distribute dividends (other than capital gain dividends) to its
beneficial owners in an amount at least equal to (A) the sum of (i) 95% of the
Trust's "REIT taxable income" (computed without regard to the dividends paid
deduction and the Trust's net capital gain) and (ii) 95% of the net income
(after tax), if any, from foreclosure property, minus (B) the sum of certain
items of noncash income. Such distributions must be paid in the taxable year to
which they relate, or in the following taxable year if declared before the Trust
timely files its tax return for such year and if paid with or before the first
regular dividend payment after such declaration. To the extent that the Trust
does not distribute all of its net capital gain or distributes at least 95%, but
less than 100%, of its "REIT taxable income," as adjusted, it will be subject to
tax thereon at the capital gains or ordinary corporate tax rates, as the case
may be. Furthermore, if the Trust should fail to distribute during each calendar
year at least the sum of (i) 85% of its REIT ordinary income for such year, (ii)
95% of its REIT capital gain income for such year, and (iii) any undistributed
taxable income from prior periods, the Trust would be subject to a 4% excise tax
on the excess of such required distribution over the amounts actually
distributed. The Trust intends to make timely distributions sufficient to
satisfy this annual distribution requirement.
 
     Under certain circumstances, the Trust may be able to rectify a failure to
meet the distribution requirement for a year by paying "deficiency dividends" to
holders of Trust Securities in a later year, which may be included in the
Trust's deduction for dividends paid for the earlier year. Thus, the Trust may
be able to avoid being taxed on amounts distributed as deficiency dividends;
however, the Trust will be required to pay interest based on the amount of any
deduction taken for deficiency dividends.
 
                                       98
<PAGE>   100
 
     Failure to Qualify. If the Trust fails to qualify for taxation as a REIT in
any taxable year, and the relief provisions do not apply, the Trust will be
subject to tax (including any applicable alternative minimum tax) on its taxable
income at regular corporate rates. Distributions to beneficial owners in any
year in which the Trust fails to qualify will not be deductible by the Trust nor
will they be required to be made. In such event, to the extent of current and
accumulated earnings and profits, all distributions to beneficial owners will be
taxable as ordinary income, and, subject to certain limitations of the Code,
corporate distributees may be eligible for the dividends received deduction.
Unless entitled to relief under specific statutory provisions, the Trust will
also be disqualified from taxation as a REIT for the four taxable years
following the year during which qualification was lost. It is not possible to
state whether in all circumstances the Trust would be entitled to such statutory
relief.
 
TAX ASPECTS OF THE TRUST'S INVESTMENT IN THE OPERATING PARTNERSHIP
 
   
     General. In the opinion of Davis Polk & Wardwell under current law the
Trust, and not the holders of the Preferred Securities, will be treated as the
owner of the Preferred L.P. Units for federal income tax purposes. Accordingly,
the Trust will include in its income its proportionate share of partnership
items for purposes of the various REIT income tests. Moreover, for purposes of
the REIT asset tests, the Trust will include its proportionate share of assets
held by the Operating Partnership. See "-- Taxation of the Trust -- Ownership of
Partnership Interests."
    
 
     Sale of the Properties. The Trust's share of any gain realized by the
Operating Partnership on the sale of any property held as inventory or primarily
for sale to customers in the ordinary course of business will be treated as
income from a prohibited transaction that is subject to a 100% penalty tax. See
"--Taxation of the Trust -- Requirements for Qualification" and "-- Taxation of
the Trust -- Income Tests." Under existing law, whether property is held as
inventory or primarily for sale to customers in the ordinary course of a
partnership's trade or business is a question of fact that depends on all the
facts and circumstances with respect to the particular transaction. The
Operating Partnership intends to hold the Properties for investment with a view
to long-term appreciation, to engage in the business of acquiring, developing,
owning, and operating the Properties (and other apartment properties) and to
make such occasional sales of the Properties, including peripheral land, as are
consistent with the Trust's investment objectives.
 
TAXATION OF TAXABLE DOMESTIC HOLDERS
 
     General. As long as the Trust qualifies as a REIT, distributions made to
the Trust's taxable domestic holders out of current or accumulated earnings and
profits (and not designated as capital gain dividends) will be taken into
account by them as ordinary income and will not be eligible for the dividends
received deduction for corporations. Distributions that are designated as
capital gain dividends will be taxed as long-term capital gains (to the extent
that they do not exceed the Trust's actual net capital gain for the taxable
year) without regard to the period for which the holder has held its Preferred
Security. It is expected that all distributions from the Trust will be
designated as ordinary income.
 
     Gain from the sale of Preferred Securities will be included in income as
capital gain assuming the securities are a capital asset in the hands of the
holder. Capital gains of individuals derived in respect of capital assets held
for more than one year are eligible for reduced rates of taxation depending upon
the holding period of such assets. In addition, any dividend declared by the
Trust in October, November or December of any year and payable to a holder of
record on a specified date in any such month shall be treated as both paid by
the Trust and received by the holder on December 31 of such year, provided that
the dividend is actually paid by the Trust during January of the following
calendar year.
 
     In general, any loss upon a sale or exchange of shares by a holder who has
held such shares for six months or less (after applying certain holding period
rules) will be treated as a long-term capital loss to the extent of
distributions from the Trust required to be treated by such holder as long-term
capital gain.

<PAGE>   101
 
RECENT LEGISLATION APPLICABLE TO REITS
 
     The Taxpayer Relief Act of 1997 enacted on August 5, 1997 (the "Act") made
various changes to the Code, including to the provisions that govern the federal
income tax treatment of REITs. These changes to the REIT provisions are
generally effective for taxable years beginning after the date of the enactment
of the Act. For most REITs, including the Trust, these changes to the REIT
provisions are therefore not effective until taxable years beginning on January
1, 1998.
 
     Changes to the REIT provisions under the Act include the following. First,
a REIT will be able to provide certain services directly without disqualifying
all of the rent from the property where the services are provided if the amount
treated as received for those services does not exceed 1% of the gross income
from the property. Second, a REIT's wholly-owned subsidiary will be treated as a
"qualified REIT subsidiary" even where the REIT had not always owned that
subsidiary. Third, the Act repeals the requirement that a REIT must derive less
than 30% of its gross income from the sale of stock or securities held for less
than one year, real property held less than four years, and property sold or
disposed of in a "prohibited transaction." Finally, a REIT will be able to elect
to retain and pay income tax on net long-term capital gains. In that event, REIT
shareholders would include in income their share of the long-term capital gains
retained by the REIT and would receive a credit for their share of the taxes
paid by the REIT.
 
TAXATION OF TAX-EXEMPT HOLDERS
 
     Based upon a published IRS ruling, distributions by the Trust to a holder
that is a tax-exempt entity will not constitute "unrelated business taxable
income" ("UBTI"), provided that the tax-exempt entity has not financed the
acquisitions of its shares with "acquisition indebtedness" within the meaning of
the Code and the Preferred Securities are not otherwise used in an unrelated
trade or business of the tax-exempt entity.
 
     Notwithstanding the preceding paragraph, however, a portion of the
dividends paid by the Trust may be treated as UBTI to certain domestic private
pension trusts if the Trust is treated as a "pension-held REIT." The Trust does
not expect to become a "pension-held REIT." If the Trust were to become a
pension-held REIT, these rules generally would only apply to certain pension
trusts that hold more than 10% of the Trust's stock.
 
TAXATION OF FOREIGN HOLDERS
 
   
     The following is a discussion of certain anticipated U.S. federal income
and estate tax consequences of the ownership and disposition of the Preferred
Securities applicable to Non-U.S. Holders of such securities. A "Non-U.S.
Holder" is any holder other than (i) a citizen or resident of the United States,
(ii) a corporation or partnership created or organized in the United States or
under the laws of the United States or of any state thereof, (iii) an estate
whose income is includible in gross income for U.S. federal income tax purposes
regardless of its source, or (iv) a trust whose income is includible in gross
income for U.S. federal income tax purposes regardless of its source. The
discussion is based on current law and is for general information only. The
discussion addresses only certain and not all aspects of U.S. federal income and
estate taxation.
    
 
   
     Recently issued United States Treasury Regulations (the "New Withholding
Tax Regulations") will be effective with respect to dividends paid after
December 31, 1998, subject to certain transition rules. The discussion below is
not intended to be a complete discussion of the New Withholding Tax Regulations,
and prospective investors are urged to consult their tax advisors with respect
to the effect the New Withholding Tax Regulations would have if adopted.
    
 
     Distributions From the Trust
 
     1. Ordinary Dividends. The portion of dividends received by Non-U.S.
Holders payable out of the Trust's current and accumulated earnings and profits
that is not attributable to capital gains of the Trust and that is not
effectively connected with a U.S. trade or business of the Non-U.S. Holder will
be subject to U.S. withholding tax at the rate of 30% (unless reduced by
treaty). In general, Non-U.S. Holders will not be considered engaged in a U.S.
trade or business solely as a result of their ownership of Preferred Securities.
In
 
                                       100
<PAGE>   102
 
cases where the dividend income from a Non-U.S. Holder's investment in Preferred
Securities is (or is treated as) effectively connected with the Non-U.S.
Holder's conduct of a U.S. trade or business, the Non-U.S. Holder generally will
be subject to U.S. tax at graduated rates, in the same manner as a U.S. Holders
are taxed with respect to such dividends (and may also be subject to the 30%
branch profits tax in the case of a Non-U.S. Holder that is a foreign
corporation).
 
   
     Under the New Withholding Tax Regulations, to obtain a reduced rate of
withholding under a treaty, a Non-U.S. Holder will generally be required to
provide an IRS Form W-8 certifying such Non-U.S. Holder's entitlement to
benefits under the treaty. The New Withholding Tax Regulations will also provide
special rules to determine whether, for purposes of determining the
applicability of a tax treaty, dividends paid to a Non-U.S. Holder that is an
entity should be treated as paid to the entity or those holding an interest in
that entity.
    
 
     2. Capital Gain Dividends. Although the Operating Partnership intends to
allocate only ordinary income to the Trust, the IRS could take the position, in
the event the Operating Partnership sells property at a gain, that a portion of
the gain should be allocated to the Trust. Under the Foreign Investment in Real
Property Act of 1980 ("FIRPTA"), a distribution made by the Trust to a Non-U.S.
Holder, to the extent attributable to gains from dispositions of United States
Real Property Interests ("USRPIs") such as the Properties ("USRPI Capital
Gains"), will be considered effectively connected with a U.S. trade or business
of the Non-U.S. holder and subject to U.S. income tax at the rate applicable to
U.S. individuals and corporations, without regard to whether the distribution is
designated by the Trust as a capital gain dividend. In addition, the Trust will
be required to withhold tax equal to 35% of the amount of dividends to the
extent the dividends constitute USRPI Capital Gains. Distributions subject to
FIRPTA may also be subject to a 30% branch profits tax in the hands of a foreign
corporate holder that is not entitled to treaty exemption.
 
     Disposition of Stock of the Trust. Unless the Trust's stock constitutes a
USRPI, a sale of such stock by a Non-U.S. Holder generally will not be subject
to U.S. taxation under FIRPTA. The stock will not constitute a USRPI if the
Trust is a "domestically controlled REIT." A domestically controlled REIT is a
REIT in which, at all times during a specified testing period, less than 50% in
value of its shares is held directly or indirectly by Non-U.S. Holders.
 
     If the Trust does not constitute a domestically controlled REIT, a Non-U.S.
Holder's sale of Preferred Securities generally will still not be subject to tax
under FIRPTA as a sale of a USRPI provided that (i) the stock is "regularly
traded" (as defined by applicable Treasury regulations) on an established
securities market (e.g., the NYSE, on which the Preferred Securities will be
listed) and (ii) the selling Non-U.S. Holder held 5% or less of the Trust's
outstanding stock at all times during a specified testing period.
 
     If gain on the sale of Preferred Securities were subject to taxation under
FIRPTA, the Non-U.S. Holder would be subject to taxation in accordance with
Section 897 of the Code, and the purchaser of the Preferred Securities could be
required to withhold 10% of the purchase price and remit such amount to the IRS.
 
   
     Capital gains on the sale of Preferred Securities that are not subject to
FIRPTA will nonetheless be taxable in the United States to a Non-U.S. Holder in
two cases: (i) if the Non-U.S. Holder's investment in Preferred Securities is
effectively connected with a U.S. trade or business conducted by the Non-U.S.
Holder, the Non-U.S. Holder will generally be subject to the same treatment as a
U.S. Holder with respect to such gain; and (ii) if the Non-U.S. Holder is a
nonresident alien who was present in the United States for 183 days or more
during the taxable year and certain other requirements are met, the nonresident
alien individual will be subject to a 30% tax on the individual's capital gain.
    
 
     Estate Tax. Preferred Securities owned or treated as owned by an individual
who is not a citizen or resident (as specially defined for U.S. federal estate
tax purposes) of the United States at the time of death will be includible in
the individual's gross estate for U.S. Federal estate tax purposes, unless an
applicable estate tax treaty provides otherwise. Such individual's estate may be
subject to U.S. federal estate tax on the property includible in the estate for
U.S. federal estate tax purposes.
 
     Information Reporting and Backup Withholding. The Trust must report
annually to the Service and to each Non-U.S. Holder the amount of dividends
(including any capital gain dividends) paid to, and the tax
 
                                       101
<PAGE>   103
 
withheld with respect to, each Non-U.S. Holder. These reporting requirements
apply regardless of whether withholding was reduced or eliminated by an
applicable tax treaty. Copies of these returns may also be made available under
the provisions of a specific treaty or agreement with the tax authorities in the
country in which the Non-U.S. Holder resides.
 
     Under current law, U.S. backup withholding (which generally is imposed at
the rate of 31% on certain payments to persons that fail to furnish the
information required under the U.S. information reporting requirements) and
information reporting will generally not apply to dividends (including any
capital gain dividends) paid on Preferred Securities to a Non-U.S. Holder at an
address outside the United States.
 
     The New Withholding Tax Regulations will alter the foregoing rules in
certain respects. Among other things, the New Withholding Tax Regulations will
provide certain presumptions under which a Non-U.S. Holder would be subject to
backup withholding and information reporting unless the Trust receives
certification from the holder of its non-U.S. status.
 
     The payment of the proceeds from the disposition of Preferred Securities to
or through a U.S. office of a broker will be subject to information reporting
and backup withholding unless the owner, under penalties of perjury, certifies,
among other things, its status as a Non-U.S. Holder, or otherwise establishes an
exemption. The payment of the proceeds from the disposition of stock to or
through a non-U.S. office of a non-U.S. broker generally will not be subject to
backup withholding and information reporting.
 
OTHER TAX CONSEQUENCES
 
     Possible Legislative or Other Actions Affecting Tax
Consequences. Prospective holders of Preferred Securities should recognize that
the present federal income tax treatment of an investment in the Trust may be
modified by legislative, judicial or administrative action at any time, and that
any such action may affect investments and commitments previously made.
Revisions in federal tax laws and interpretations thereof could adversely affect
the tax consequences of an investment in the Trust.
 
     State and Local Taxes. The Trust and its holders may be subject to state or
local taxation in various state or local jurisdictions, including those in which
it, the Operating Partnership or they transact business or reside. The state and
local tax treatment of the Trust and its holders may not conform to the federal
income tax consequences discussed above. Consequently, prospective holders of
Preferred Securities should consult their tax advisors regarding the effect of
state and local tax laws on an investment in the Trust.

     The Representatives have advised the Trust that the Underwriters propose to
offer the Series A Preferred Securities in part directly to the public at the
initial public offering price set forth on the cover page of this Prospectus,
and in part to certain securities dealers at such price less a concession not in
excess of $          per Series A Preferred Security. The Underwriters may
allow, and such dealers may reallow, a discount not in excess of $          per
Series A Preferred Security to certain other dealers. After the initial public
offering, the public offering price, concession and discount may be changed.
 
   
     At the request of the Company, the Underwriters have reserved for sale, at
the initial public offering price, up to           of the Series A Preferred
Securities offered hereby to be sold to certain officers, directors and
employees of the Company. The number of Series A Preferred Securities available
for sale to the general public will be reduced to the extent such persons
purchase such reserved Series A Preferred Securities. Any Series A Preferred
Securities which are not orally confirmed for purchase within one day of the
pricing of the Offering will be offered by the Underwriters to the general
public on the same terms as the other Series A Preferred Securities offered
hereby.
    
 
   
     The Trust has granted an option to the Underwriters, exercisable for a
period of 30 days after the date of this Prospectus, to purchase up to 900,000
additional Series A Preferred Securities solely to cover overallotments, if any,
at the price to public, less the underwriting discount set forth on the cover
page of this Prospectus. If the Underwriters exercise this option, each
Underwriter will have a firm commitment, subject to certain conditions, to
purchase approximately the same percentage thereof which the number of Series A
Preferred Securities to be purchased by it in the foregoing table bears to the
6,000,000 Series A Preferred Securities initially offered hereby.
    
 
   
     Since the proceeds of the sale of Series A Preferred Securities will be
used to purchase the Series A Preferred L.P. Units of the Operating Partnership,
the Purchase Agreement provides that the Operating Partnership will pay as
compensation ("Underwriters' Compensation") for the Underwriters' arranging the
investment therein of such proceeds, an amount in immediately available funds of
$          per Series A Preferred Security (or $          in the aggregate)
($          in the aggregate if the Underwriters' over allotment option is
exercised in full) for the accounts of the several Underwriters.
    
 
                                       103
<PAGE>   105
 
   
     The Trust and the Operating Partnership, have agreed that they will not,
directly or indirectly, for a period of 90 days after the date of the Purchase
Agreement, except with the prior written consent of Merrill Lynch, offer, sell,
or enter into any agreement to sell, or otherwise dispose of (a) any securities
of the Trust (other than the Series A Preferred Securities offered hereby and
the Common Securities) and (b) any Preferred L.P. Units (other than the Series A
Preferred L.P. Units to be sold to the Trust as described in this Prospectus) or
any other security of the Operating Partnership that is substantially similar to
the Series A Preferred L.P. Units.
    
 
   
     Application has been made to list the Series A Preferred Securities on the
NYSE under the symbol "IAC Pr A." If approved for listing, trading of the Series
A Preferred Securities on the NYSE is expected to commence within 30 days after
initial delivery of the Series A Preferred Securities. The Representatives have
advised the Trust that they intend to make a market in the Series A Preferred
Securities prior to the commencement of trading on the NYSE. The Representatives
will have no obligation to make a market in the Series A Preferred Securities,
however, and may cease market making activities, if commenced, at any time.
    
 
     Prior to this Offering, there has been no public market for the Series A
Preferred Securities. In order to meet one of the requirements for listing the
Series A Preferred Securities on the NYSE, the Underwriters will undertake to
sell lots of 100 or more Series A Preferred Securities to a minimum of 400
beneficial holders.
 
   
     The Operating Partnership and the Company have agreed to indemnify the
Underwriters against, or contribute to payments that the Underwriters may be
required to make in respect of, certain liabilities, including liabilities under
the Securities Act of 1933, as amended.
    
 
     The Underwriters have informed the Trust that the Underwriters do not
intend to confirm sales accounts over which they exercise discretionary
authority in excess of 5%.
 
     Until the distribution of the Series A Preferred Securities is completed,
rules of the Commission may limit the ability of the Underwriters and certain
selling group members to bid for and purchase the Series A Preferred Securities.
As an exception to these rules, the Representatives are permitted to engage in
certain transactions that stabilize the price of the Series A Preferred
Securities. Such transactions consist of bids or purchases for the purpose of
pegging, fixing or maintaining the price of the Series A Preferred Securities.
 
     If the Underwriters create a short position in the Series A Preferred
Securities in connection with the Offering, i.e., if they sell more shares of
Series A Preferred Securities than are set forth on the cover page of this
Prospectus, the Representatives may reduce that short position by purchasing
Series A Preferred Securities in the open market. The Representatives may also
elect to reduce any short position by exercising all or part of the
over-allotment options described above.
 
     The Representatives may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
shares of Series A Preferred Securities in the open market to reduce the
Underwriters' short position or to stabilize the price of the Series A Preferred
Securities, they may reclaim the amount of the selling concession from the
Underwriters and selling group members who sold those shares as part of the
Offering.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of a security to the extent that it were
discourage resales of the security.
 
     Neither the Trust nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Series A Preferred Securities. In
addition, neither the Trust nor any of the Underwriters makes any representation
that the Representatives will engage in such transactions or that such
transactions, once commenced, will not be discontinued without notice.
 
   
     The Trust has been advised that affiliates of Salomon Brothers may be
deemed to own approximately 977,627 shares of the Common Stock of the Company,
representing approximately 4.92% of the outstanding shares of Common stock of
the Company.
    
 
     Each of the Underwriters engages in transactions with, and from time to
time has performed services for, the Company and the Operating Partnership in
the ordinary course of business. J.P. Morgan Securities Inc.,

one of the Underwriters, is syndication agent, and Morgan Guaranty Trust Company
of New York, an affiliate of J.P. Morgan Securities Inc., is a lender, under the
Credit Facility. Approximately $     million of the net proceeds from the
Offering will be used to repay Morgan Guaranty Trust Company of New York for a
portion of the outstanding borrowings of the Operating Partnership under the
Credit Facility. See "Use of Proceeds." Since the amount to be repaid to Morgan
Guaranty Trust Company of New York exceeds 10% of the net proceeds from the sale
of the Series A Preferred Securities, the offering of the Series A Preferred
Securities is being made pursuant to the provisions of Rule 2710(c)(8) of the
Conduct Rules of the National Association of Securities Dealers, Inc. See

To the Trustees
IAC Capital Trust
 
     We have audited the accompanying balance sheet of IAC Capital Trust, a
Delaware Business Trust, as of October 31, 1997. This balance sheet is the
responsibility of management. Our responsibility is to express an opinion on the
balance sheet based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance about whether the balance sheet is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the balance sheet. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall balance sheet presentation. We
believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the balance sheet referred to above presents fairly, in all
material respects, the financial position of IAC Capital Trust at October 31,
1997, in conformity with generally accepted accounting principles.

                             NOTES TO BALANCE SHEET
 
NOTE 1 -- ORGANIZATION AND FORMATION
 
   
     IAC Capital Trust (the "Trust") is a business trust formed on October 31,
1997 under the Delaware Business Trust Act. Irvine Apartment Communities, Inc.
(the "Company") and certain members of management of the Company will acquire
all of the Common Securities of the Trust, representing common undivided
beneficial interests in all of the assets of the Trust, for an aggregate
consideration of $5,000. The Company has established a trust estate as of
October 31, 1997 through a cash contribution of $10.
    
 
   
     Upon issuance by the Trust of Series A Preferred Securities as contemplated
by this Prospectus and Registration Statement (the "Offering"), the holders
thereof will own all of the issued and outstanding Series A Preferred Securities
of the Trust. From time to time the Trust may issue additional series of
Preferred Securities and invest the proceeds of any such issuances in additional
series of Preferred L.P. Units of Irvine Apartment Communities, L.P. (the
"Operating Partnership.") Each series of Preferred Securities will represent a
preferred undivided beneficial interest in the assets of the Trust subject to
its priority and payment terms, and are not secured by any assets of the
Operating Partnership or any of its affiliates. The Series A Preferred
Securities will bear a cumulative cash distribution rate which will be
established when the securities are issued and will have a stated maturity of
December 31, 2092.
    
 
   
     The Trust is a limited purpose financing vehicle established by the Company
and the Operating Partnership and exists for the purpose of (a) issuing its
Common Securities as described above, (b) issuing its Preferred Securities (c)
investing the proceeds from the sale of each series of Preferred Securities in a
series of Preferred L.P. Units of the Operating Partnership and (d) engaging in
such other activities as are necessary, convenient or incidental thereto. The
proceeds from the sale of the Common Securities of the Trust will be invested in
an interest bearing account in, or a certificate of deposit of, a bank. The
rights of the holders of the Preferred Securities and the Common Securities
(collectively, the "Trust Securities"), including economic rights, rights to
information and voting rights, are as set forth in the Trust's Declaration and
related Business Trust Act. The Preferred Securities have no voting rights
except in limited circumstances. The Trust's Declaration does not permit the
incurrence by the Trust of any indebtedness for borrowed money or the making of
any investment other than in the Preferred L.P. Units of the Operating
Partnership and as described above in connection with the investment of the
proceeds from the sale of Common Securities.
    
 
     The Operating Partnership has agreed to reimburse all obligations (other
than with respect to the Trust Securities) and all costs and expenses of the
Trust, including the fees and expenses of the Trustees and any income taxes,
duties and other governmental charges, and all costs and expenses with respect
thereto, to which the Trust may become subject, except for withholding taxes.
 
   
NOTE 2 -- INVESTMENT IN IRVINE APARTMENT COMMUNITIES, L.P.
    
 
   
     Upon closing of the Offering and the related investment of the proceeds in
the Preferred L.P. Units of the Operating Partnership, the Trust will account
for its investment in the Operating Partnership using the equity method of
accounting.
    
 
   
NOTE 3 -- INCOME TAXES
    
 
     After the Offering, the Trust intends to make an election to be taxed as a
real estate investment trust ("REIT") under the Internal Revenue Code (the
"Code"). As a REIT, the Trust generally will not be subject to federal income
tax if it distributes at least 95% of its REIT taxable income to its
shareholders. REITs are subject to a number of organizational and operational
requirements. If the Trust fails to qualify as a REIT in any taxable year, the
Trust will be subject to federal income tax (including any applicable
alternative minimum tax) on its taxable income at regular corporate tax rates.
Even if the Trust qualifies for taxation as a REIT, the Trust may be subject to
state and local taxes on its income and property and to federal income and
excise taxes on its undistributed income.

To the Partners
Irvine Apartment Communities, L.P.

Apartment Communities, L.P., a Delaware limited partnership, as of December 31,
1996 and 1995, and the related consolidated statements of operations, changes in
partners' capital and cash flows for each of the three years in the period ended

beginning on page F-22. These financial statements and schedule are the
responsibility of management. Our responsibility is to express an opinion on
these financial statements and schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Irvine
Apartment Communities, L.P. at December 31, 1996 and 1995, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1996, in conformity with generally accepted accounting
principles. Also, in our opinion, the related financial statement schedule, when
considered in relation to the basic financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (DOLLARS IN THOUSANDS, EXCEPT PER UNIT AMOUNTS)
 
NOTE 1 -- ORGANIZATION AND BASIS OF PRESENTATION
 
     Irvine Apartment Communities, L.P., a Delaware limited partnership (the
"Operating Partnership"), was formed on November 15, 1993. In connection with an
initial public offering of common shares on December 8, 1993, Irvine Apartment
Communities, Inc. (the "Company") obtained a general partnership interest in and
became the sole managing general partner of the Partnership. The Irvine Company
(the "Limited Partner") transferred 42 apartment communities and a 99% interest
in a limited partnership which owns one apartment community to the Operating
Partnership. The Operating Partnership's management and operating decisions are
under the unilateral control of the Company. All management powers over the
business and affairs of the Operating Partnership are vested exclusively in the
Company. No limited partner of the Operating Partnership has any right to
exercise control or management power over the business and affairs of the
Operating Partnership. As of December 31, 1996, the Company had a 45.4% general
partnership interest and The Irvine Company had a 54.6% limited partnership
interest in the Operating Partnership.
 
     The Operating Partnership owns, operates and develops apartment communities
in Orange County, California. The Operating Partnership utilizes independent
third-party property management and construction management firms. As of
December 31, 1996 the Operating Partnership owned and operated 52 properties
containing 13,656 operating apartment units and 864 units under construction
(collectively, the "Properties"). Until July 31, 2020, the Operating Partnership
has the exclusive right, but not the obligation, to acquire land from The Irvine
Company for development of additional apartment communities on the Irvine Ranch
(see Note 7 to the consolidated financial statements).
 
     Profits and losses are generally allocated to the Company and to the
Limited Partner based upon their respective ownership interests in the Operating
Partnership. The partnership agreement provides for the allocation of certain
costs to The Irvine Company. As of December 31, 1995, all such allocations had
been completed.
 
     The accompanying financial statements include the consolidated accounts of
the Operating Partnership and its financially controlled subsidiary. All
intercompany accounts and transactions have been eliminated in consolidation.
 
     Under the terms of the partnership agreement, all costs incurred by the
Company relating to the ownership of interests in and operation of the Operating
Partnership, including the compensation of its officers and employees, stock
incentive plans, director fees and the costs and expenses of being a public
company, are reimbursed by the Operating Partnership. In addition, the Limited
Partner has the right, but not the obligation, to match on the same terms and
conditions any capital contributions made by the Company based on the pro rata
ownership interest at the time of such contribution.
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities as of
December 31, 1996 and 1995, and the revenues and expenses for the three years
ended December 31, 1996. Actual results could differ from those estimates.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Real Estate Assets and Depreciation: Real estate assets, which are held as
long-term investments, are stated at cost less accumulated depreciation.
Impairment losses on long-lived assets used in operations are recorded when
events and circumstances indicate that the assets are impaired and the
undiscounted cash flows estimated to be generated by those assets are less than
the carrying amounts. Land and infrastructure costs are allocated to properties
based on relative fair value. Costs related to the development and construction
of properties are capitalized as incurred. Interest and property taxes are
capitalized to apartment communities
 
                                      F-10

which are under active development. When a building within a community under
construction is completed and held available for occupancy, the related costs
are expensed.
 
Repair and maintenance expenditures are expensed as incurred. Major replacements
and betterments are capitalized and depreciated over their useful lives.
Depreciation is computed on a straight-line basis over the useful lives of the
properties (principally forty years for buildings; twenty years for siding,
roofs and balconies; fifteen years for plumbing and air conditioning equipment;
ten years for pools, tennis courts, parking lots and driveways; and five to ten
years for furniture and fixtures).
 
     Cash and Cash Equivalents: The Operating Partnership considers all highly
liquid investments with a maturity when purchased of three months or less to be
cash equivalents.
 
     Restricted Cash: Restricted cash is comprised of reserve accounts for
capital replacements, property taxes and insurance. These restricted funds are
subject to supervision and approval by a lender or a government agency. The
terms of the contract with the government agency contain certain restrictions
concerning operating policies, rental charges, operating expenditures,
distributions to owners and other matters.
 
     Deferred Financing Costs: Costs incurred in obtaining long-term financing
or costs to buy down or hedge interest costs are deferred and amortized over the
term of the related debt agreements using the effective interest method.
 
     Revenue Recognition: The Operating Partnership leases apartment units to a
diverse resident base for terms of one year or less. Credit investigations are
performed for all prospective residents and security deposits are also obtained.
Resident receivables are evaluated for collectibility. Rental revenue is
recognized on an accrual basis as it is earned over the life of the lease.
Interest income is recorded as earned.
 
     Interest Expense: Interest rates are substantially fixed for specified
periods through interest rate swaps and buy-down agreements for certain debt
instruments. These financial instruments are entered into as a hedge against the
interest exposure from variable rate debt. The differences paid or received on
swaps and related agreements are included in interest expense as yield
adjustments.
 
     Income Taxes: The Operating Partnership's taxable income is reportable by
its partners. Accordingly, no provision has been made for federal income taxes
in the accompanying statements of operations.
 
     Per Unit Data: The computation of net income per partnership unit is based
on the weighted average number of partnership units outstanding and excludes the
effect of the Company's stock options and performance awards since their
dilutive effect is minimal.
 
     Reclassifications: Certain amounts in the 1995 and 1994 financial
statements have been reclassified to conform with financial statement
presentations in 1996.
 
NOTE 3 -- MORTGAGES AND NOTES PAYABLE
 
     Line Of Credit: In November 1995, the Operating Partnership obtained a $175
million unsecured revolving credit facility. The line of credit facility has a
term of two years and at the Operating Partnership's option may be converted to
a two-year term loan at maturity. This revolving credit facility is available to
finance the Operating Partnership's ongoing rental property development program
and for general working capital needs. Borrowings under the line of credit bear
interest at the Operating Partnership's option at variable rates based on the
Eurodollar rate plus a spread of 1.5% or the Prime rate. The Operating
Partnership is also obligated to pay a fee on the average daily amount of the
unused portion of the commitment, and quarterly agent fees on the commitment
amount. The Company and the Operating Partnership must comply with certain
affirmative and negative covenants, including limitations on distributions to
its partners,
 
                                      F-11

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                (DOLLARS IN THOUSANDS, EXCEPT PER UNIT AMOUNTS)
 
limitations on payment of distributions, and the maintenance of certain net
worth, cash flow and financial ratios. At December 31, 1996 the Company and the
Operating Partnership were in compliance with all of these covenants. As of
December 31, 1996, $16 million was outstanding and $159 million was available
under the line of credit. In February 1997, the Operating Partnership's line of
credit was increased to $250 million.
 
   
     Tax-Exempt Mortgage Bond Financings: On May 25, 1995, the Operating
Partnership refinanced all $324,816 of its outstanding tax-exempt mortgage debt.
As a result of a new 30-year refunding agreement, which is backed by credit and
liquidity support from the Federal National Mortgage Association ("Fannie Mae"),
the Operating Partnership obtained tax-exempt mortgage bond financings of
$334,190 maturing in June 2025. Standard & Poor's Rating Group assigned ratings
of AAA/A-1+ to the bonds based on the collateral agreement with Fannie Mae. In
connection with the refinancing transaction, the Operating Partnership recorded
an extraordinary charge of $23,427 to write off deferred financing costs related
to the debt that was refinanced.
    
 
     The tax-exempt financings represent loans payable that are collateralized
by twenty-three properties with a net book value of $281,211 as of December 31,
1996. Monthly principal and interest payments are made to a trustee, which in
turn pays the bondholders when interest is due. The bonds are remarketed
periodically and bear interest at short-term floating rates. The floating rates
have been fixed through interest rate swap agreements. (See Interest Rate Swap
Agreements.) Principal payments are amortized over a 30-year period and are held
in a principal payment fund. The tax-exempt mortgage bond financings, before
giving effect to the swap agreements, had an average floating interest rate
inclusive of fees of 4.76% in December 1996.
 
     Conventional Mortgage Financings: Conventional mortgages are collateralized
by apartment communities with a net book value of $148,493 as of December 31,
1996. The mortgages are generally due in monthly installments and mature at
various dates through 2018. Prior to the Offering, interest rates were fixed at
rates which ranged from 7.75% to 9.63%, with a weighted average rate of 8.69%.
In connection with the Offering, the interest rates were adjusted to market
rates for specified periods of time and currently range from 5.82% to 7.75%. As
of December 31, 1996 the weighted average interest rate was 6.45%. Including the
amortization of deferred financing costs the all-in interest rate was 8.16%. The
interest reduction periods expire prior to or at the loan maturity dates and
range from 1997 to 2008.
 
     Mortgage Notes Payable to The Irvine Company: Two of the Operating
Partnership's apartment communities are financed by mortgage notes payable to
The Irvine Company. These mortgage notes totaled $51,227 and $52,011 at December
31, 1996 and 1995, respectively. The mortgage notes are collateralized by
all-inclusive trust deeds on each of the apartment communities financed. They
bore fixed interest rates of 5.75% at December 31, 1996, are fully amortizing
and mature in 2015 and 2024. Interest incurred on the mortgage notes payable to
The Irvine Company totaled $2,966, $3,010 and $3,055 for the years ended
December 31, 1996, 1995 and 1994, respectively. The mortgage notes payable to
The Irvine Company "wrap around" secured first trust deed notes payable to
third-party financial institutions. The secured first trust deed notes totaled
$51,363 and $52,030 as of December 31, 1996 and 1995, respectively.
 
     Tax-Exempt Assessment District Debt: In conjunction with the purchase of
land, the Operating Partnership assumed $2,771 in 1996 and $4,184 in 1995 in
tax-exempt assessment district debt which represents debt issued by municipal
government authorities to finance the construction of infrastructure and
improvements. The debt obligations are repaid by the Operating Partnership
through assessments.
 
     Interest Rate Swap Agreements: The Operating Partnership uses interest rate
swap agreements to effectively convert its floating rate tax-exempt mortgage
bond financings to a fixed-rate basis, thus reducing the impact on future income
of fluctuations in interest rates. At December 31, 1996, the Operating
Partnership had interest rate swap agreements on notional amounts totaling
$329,248 which pay fixed rates of interest and receive floating rates of
interest based on a municipal bond index that is remarketed weekly. The

swap agreement periods mature from 2002 to 2007. The swap counterparties are
primarily financial institutions rated AAA by Standard & Poor's. The differences
to be paid or received are accrued and included in interest expense as a yield
adjustment and the related amount payable or receivable from counterparties is
included in other assets or accrued liabilities. Additionally, the Operating
Partnership restructured several interest rate swaps related to the retired
tax-exempt bonds in May 1995. These transactions reduce the interest expense on
tax-exempt mortgage bond financings by approximately 30 basis points per year
through 2001. At December 31, 1996, the average fixed interest rate paid to the
counterparties was 5.10% and the average variable interest rate received was
3.64%. This resulted in a net interest payable of $381 which was settled in the
first week of January 1997. Based on prevailing interest rates at December 31,
1996, the interest rate swap agreements have a fair value of negative $4
million.
 
     Capitalized Interest: The Operating Partnership capitalizes interest on
projects actively under development using qualifying asset balances and
applicable weighted average interest rates. The average qualifying asset balance
for projects under development was approximately $40 million for the year ended
December 31, 1996. Interest capitalized was $3,151, $6,779 and $1,261 in 1996,
1995 and 1994, respectively. Interest incurred totaled $32,657, $32,673 and
$27,617 for the years ended December 31, 1996, 1995 and 1994, respectively.
 
     Other Matters: Mortgages and notes payable totaling $183,829 at December
31, 1996 are subject to prepayment penalties.

NOTE 4 -- FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts reported in the balance sheet for financial
instruments approximate their fair value except as discussed below. The fair
values of mortgage notes payable to The Irvine Company are estimated using
discounted cash flow analyses and the Operating Partnership's current estimated
borrowing rates for similar types of borrowing arrangements. The interest rate
used in the fair value calculation was 7.72% based on the terms of the loans. As
of December 31, 1996, the fair value of the mortgage notes payable to The Irvine
Company was $42,590. See Note 3 to the consolidated financial statements for a
discussion of the fair value of the interest rate swap agreements.
 
NOTE 5 -- PARTNERS' CAPITAL
 
     On May 8, 1995, the Company filed a shelf registration statement with the
Securities and Exchange Commission providing for the issuance from time to time
of up to $250 million of common stock, preferred stock, debt securities, and
warrants to purchase common stock, preferred stock and debt securities. The
Operating Partnership plans to use the proceeds raised from any securities
issued under the shelf registration and any matching issuance of partnership
units to the Limited Partner for general corporate purposes, including the
development of new apartment communities, acquisitions and the repayment of
existing debt.
 
     On August 9, 1995, the Company sold, pursuant to its shelf registration
statement, 5.175 million shares of common stock at $17.25 per share.
Concurrently, the Limited Partner, pursuant to its rights under the partnership
agreement, purchased 1.5 million partnership units at $17.25 per unit. Such
units are exchangeable for common stock on a one-for-one basis, subject to
adjustment and certain limitations. The net proceeds from the two transactions
totaled $109,329. Proceeds of $80,100 were used to repay amounts outstanding
under construction and revolving lines of credit. The balance of $29,229 was
used to fund new construction.
 
     Pursuant to its shelf registration statement, on July 3, 1996, the Company
completed the sale of 1.49 million shares of common stock at $20.125 per share.
The proceeds from this offering of $30 million together with proceeds from the
sale of newly issued partnership units to the Limited Partner (see Note 6 to the
consolidated financial statements), totaled $60 million. Proceeds were used to
repay $43 million of debt outstanding under the revolving line of credit. The
remaining proceeds were used to fund ongoing development programs and for
general corporate purposes. Availability under the Company's shelf registration
statement was $130.7 million at December 31, 1996.

                (DOLLARS IN THOUSANDS, EXCEPT PER UNIT AMOUNTS)
 
     On February 20, 1997, the Company sold, pursuant to its shelf registration
statement, 1.15 million shares of common stock at $27.50 per share.
Concurrently, the Limited Partner purchased 1.39 million additional partnership
units at $26.06 per unit (which is equal to the public offering price of the
common stock less an amount equivalent to the underwriting discount) which are
exchangeable for common stock on a one-for-one basis, subject to adjustment and
certain limitations. The proceeds from the two transactions totaled $66 million
and were used to repay all indebtedness outstanding under the revolving line of
credit, and will be used for general corporate purposes, including ongoing
development activities on and off the Irvine Ranch. After the above transaction,
availability under the Company's shelf registration statement is approximately
$99 million.

year ended December 31, 1996. The amounts for the corresponding periods in 1995
and 1994 were $106 and $160, respectively. The Irvine Company and the Operating
Partnership jointly purchase employee health care insurance and property and
casualty insurance. In addition, the Operating Partnership incurred rent
totaling $349, $270 and $203 for the years ended December 31, 1996, 1995 and
1994, respectively, related to leases with The Irvine Company that expire in
1997 and 1998. For the year ended December 31, 1996, The Irvine Company
contributed $354, or the maximum allowable in connection with stock issuances
under the dividend reinvestment and additional cash investment plan.
 
     In the third quarter of 1994, the Operating Partnership acquired four sites
for development of 1,695 units for $19,703 from The Irvine Company. As partial
financing for these four sites, the Operating Partnership elected to assume
$15,656 in tax-exempt assessment district debt and paid $4,047 in cash.
 
     In March 1995, the Operating Partnership acquired a 512-unit development
site known as Newport Ridge for $9,542 from The Irvine Company. As partial
financing for the acquisition of the site, the Operating Partnership elected to
assume $4,184 of tax-exempt assessment district debt. The balance of $5,358 was
paid through the issuance of 336,432 additional partnership units in the
Operating Partnership to The Irvine Company. In November 1995, the Operating
Partnership acquired a 300-unit development site known as Baypointe from The
Irvine Company for $4,190, of which $1,967 was paid through the issuance of
113,372 additional partnership units in the Operating Partnership to The Irvine
Company. The partnership units are exchangeable for common stock of the Company
on a one-for-one basis, subject to adjustment and certain limitations.
 
     In March 1996, the Operating Partnership acquired a land site for $3.3
million from The Irvine Company for the development of 227 rental units,
pursuant to the Land Rights Agreement between the Operating Partnership and The
Irvine Company. The Company's board committee of independent directors approved
the purchase in accordance with the Land Rights Agreement. As partial financing
for the site acquisition, the Operating Partnership assumed $2.8 million in
tax-exempt assessment district debt. The balance of the purchase price was paid
through the issuance of 28,358 additional partnership units in the Operating
Partnership to The Irvine Company.
 
     Concurrent with the Company's common stock offering on July 3, 1996 (see
Note 5 to the consolidated financial statements), The Irvine Company, pursuant
to its rights under the partnership agreement, purchased 1.49 million
partnership units at a price equal to the public offering price of $20.125 per
common share of stock, or a total of $30 million. These units are exchangeable
for common stock on a one-for-one basis, subject to adjustment and certain
limitations.
 
     On July 29, 1996, the Operating Partnership acquired a land site for $3.5
million from The Irvine Company for the development of 245 rental units pursuant
to the Land Rights Agreement between the Operating Partnership and The Irvine
Company. The Company's board committee of independent directors approved the
purchase in accordance with the Land Rights Agreement. Of the total purchase
price, $2.4 million was paid through the issuance of 115,544 additional
partnership units in the Operating Partnership to The Irvine Company.
 
     On December 23, 1996, the Operating Partnership acquired a land site for

price was paid through the issuance of 244,857 additional partnership units in
the Operating Partnership to The Irvine Company.
 
     One of the Company's directors is chairman of a bank which participates in
the Operating Partnership's line of credit. Based on the bank's percentage
participation in the credit facility, the Operating Partnership estimates that
the amount of interest and fees paid to the bank totaled $245, $388 and $96 in
1996, 1995 and 1994, respectively.
 
NOTE 7 -- LAND RIGHTS AGREEMENT WITH THE IRVINE COMPANY
 
     The Operating Partnership and The Irvine Company are parties to an
exclusive land rights and non-competition agreement (the "Land Rights
Agreement"). This agreement, which extends through July 31, 2020, provides the
Operating Partnership with the exclusive right, but not the obligation, to
acquire additional land sites which have been entitled for residential use and
designated by The Irvine Company as ready for apartment development in
accordance with the Master Plan. The determination to exercise an option with
respect to a site is made solely by a majority of a committee of independent
directors of the Company (the "Independent Directors Committee"), whose members
are unaffiliated with The Irvine Company. In addition, The Irvine Company and
its chairman, Donald Bren, have agreed to conduct their apartment community
development and ownership activities on the Irvine Ranch solely through the
Operating Partnership.
 
     Under terms of the Land Rights Agreement, through July 31, 2000, the
purchase price for any apartment community sites acquired may be paid with
either cash, common stock or limited partnership units at the option of the
Company. After July 31, 2000, the choice of consideration will revert to The
Irvine Company. In addition, the purchase price for future apartment sites
encompassing the next 505 apartment units the Operating Partnership develops
will be set at an amount such that each project's budgeted pro forma unleveraged
return on costs for the first twelve months following stabilized occupancy will
be between 10.0% and 10.5%. However, in no event shall the purchase price for
each such site exceed 95% of the value of such site as determined by independent
appraisals.
 
NOTE 8 -- STOCK PLANS
 
     Under the terms of the partnership agreement, payments under the Company's
stock incentive plans are reimbursed by the Operating Partnership.

Offering. Additionally, grants of fully vested options to purchase 1,000 shares
of common stock, and matching partnership units, at the market price on the
grant date were made to each independent director immediately following each
annual shareholders' meeting beginning in 1995. These options are fully vested
when granted and are exercisable for ten years from the grant dates.

</TABLE>
 
     Equity Compensation Plans: The Operating Partnership applies APB Opinion 25
and related interpretations in accounting for its equity compensation plans as
described above. Accordingly, no compensation cost has been recognized for its
stock option plans. Compensation cost for the Company's other stock-based
compensation plans has been determined utilizing the fair value of the award
over the service period. Had the Operating Partnership applied FAS Statement 123
for stock-based compensation, it would result in net income and earnings per
unit amounts that approximate the amounts reported. Under FAS Statement 123, the
fair value for options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted average assumptions for 1995
and 1996, respectively: risk-free interest rates of 7.15% and 6.46%; dividend
yields of 8.49% and 7.09%; volatility factors of the expected market price of
the Company's common stock of 0.242 and 0.204; and a weighted average expected
life of the options of seven years.
 
NOTE 9 -- SAVINGS PLAN
 
     Effective January 1, 1994, the Company implemented a defined contribution
401(k) benefit plan covering substantially all employees who have satisfied
minimum age and service requirements. The Company matches employee contributions
up to 50%, within certain limits, which is accrued as incurred. The Company also
makes contributions to this plan for each participant, generally equal to 3% of
the participant's base salary. The aggregate cost of these contributions was
$122, $95 and $82 in 1996, 1995 and 1994, respectively.
 
NOTE 10 -- AGREEMENTS, COMMITMENTS AND CONTINGENCIES
 
     Management Agreements: The Operating Partnership has management agreements
with unaffiliated property management companies to maintain and manage the
operations of the properties. Management fees range from 2.5% to 3.25% of
revenues depending on the size of the property (resulting in a weighted average
rate of approximately 2.8% of revenues). These agreements are renewable annually
and are generally cancelable on 30 days' notice. Included in operating expenses
are costs incurred by the management companies on behalf of the Operating
Partnership.
 
     Litigation: The Operating Partnership is party to various legal actions
which are incidental to its business. Management believes that these actions
will not have a material adverse effect on the Operating Partnership's
consolidated financial position.

     Assessment Districts: In some of the local jurisdictions within Orange
County where the Predecessor developed property, assessment districts were
formed by local governments to finance major infrastructure improvements. At
December 31, 1996, the Operating Partnership had $39.0 million of assessment
district debt, of which $21.9 million was reflected in the balance sheet.
 
     Exchange Rights: The Irvine Company has the right to exchange up to
one-third of the total partnership units it owns for shares of common stock of
the Company in each twelve-month period commencing on December 1 of each year at
an exchange ratio of one-to-one, subject to adjustment in certain events. These
exchanges are subject to certain restrictions including percentage ownership
limits.
 
     Company's Obligation to Purchase Tendered Partnership Units: The Limited
Partner has the right to sell to the Company for cash generally up to one-third
of its partnership units in each twelve-month period commencing on December 1 of
each year. These sales are subject to certain restrictions. The Company is to
purchase the tendered interests at a purchase price equal to the average of the
daily market prices for the common stock of the Company for the ten consecutive
trading days immediately preceding the date of receipt by the Company of a
notice of cash tender. The Company is to pay for these interests solely with the
net proceeds of an offering of the Company's common stock. The Company would
bear the costs of sale (other than underwriting discounts and commissions). The
Limited Partner would bear all market risk if the market price at closing was
less than the purchase price as determined on the date of tender. Any proceeds
of the offering in excess of the purchase price would be for the sole benefit of
the Company.
 
     Rent Restrictions: As of December 31, 1996, 21% of the apartment units
within the Operating Partnership's portfolio were required to be set aside for
residents within certain income levels and had limitations on the rent that
could be charged to such tenants. The rental revenue from five of these projects
includes governmental rent subsidy payments of $3,977, $4,023 and $3,932 for the
years ended December 31, 1996, 1995 and 1994, respectively.

Notes:
 
(a) The aggregate cost of land and buildings for federal income tax purposes is
    approximately $654,007 (unaudited).
 
(b) The gross amount at which buildings and improvements are carried represent
    historical cost amounts incurred in the development of the projects and
    capital improvements incurred subsequent to the completion of construction.
    Prior to the General Partner's December 1993 initial public offering, the
    gross land, buildings and improvements amounts represent The Irvine
    Company's historical cost basis.
 
(c) Encumbrances represent debt secured by deeds of trust.
 
(d) Land acquired from The Irvine Company is recorded at cost based on the
    purchase price.
 
(e) Estimated useful lives are five to seven years for furniture and fixtures,
    five to twenty years for improvements and forty years for buildings.

                              FINANCIAL STATEMENTS
 
NOTE 1 -- ORGANIZATION
 
     Irvine Apartment Communities, Inc. (the "Company"), operates as a real
estate investment trust ("REIT") under the Internal Revenue Code of 1986, as
amended. In connection with the Company's initial public offering of common
stock (the "Offering"), the Company obtained a general partnership interest in
and became the sole managing general partner of Irvine Apartment Communities,
L.P., a Delaware limited partnership (the "Operating Partnership"). The
Operating Partnership was formed on November 15, 1993 and began operations as of
December 8, 1993, the date of the Offering. In connection with the Offering, The
Irvine Company transferred 42 apartment communities and a 99% interest in a
limited partnership which owns one apartment community to the Operating
Partnership. At September 30, 1997 the Company had a 45.2% general partnership
interest in and was the sole managing general partner of the Operating
Partnership. At September 30, 1997, The Irvine Company had a 54.6% limited
partnership interest in the Operating Partnership. On February 4, 1997, the
Operating Partnership acquired the assets of Thompson Residential Company, Inc.
(see Note 5). The purchase price was paid by the issuance of 74,523 limited
partnership units in the Operating Partnership. At September 30, 1997, Thompson
Residential Company, Inc. had a 0.2% limited partnership interest in the
Operating Partnership. The Operating Partnership's management and operating
decisions are under the unilateral control of the Company. The Company was
incorporated in Delaware on September 10, 1993. On May 2, 1996, the Company
changed its state of incorporation from Delaware to Maryland.
 
   
     The Company is a self-administered equity REIT engaged in the operation and
development (through the Operating Partnership) of apartment communities in
Orange County, California and, beginning in 1997, other locations in California.
The Operating Partnership utilizes independent third party property management
and construction management firms. As of September 30, 1997 the Operating
Partnership owned 55 apartment communities representing 14,991 apartment units
and 1,110 units under construction (collectively, the "Properties"). The
Operating Partnership broke ground on its first "off-Ranch" apartment community,
located in Northern California's Silicon Valley, in May 1997. On June 30, 1997,
the Operating Partnership acquired a 923-unit apartment community in the La
Jolla region of north San Diego County (see Note 6). Until July 31, 2020, the
Operating Partnership has the exclusive right, but not the obligation, to
acquire land from The Irvine Company for development of additional apartment
communities on the Irvine Ranch.
    
 
NOTE 2 -- BASIS OF PRESENTATION
 
     The accompanying financial statements include the consolidated accounts of
the Operating Partnership and its financially controlled subsidiary. All
intercompany accounts and transactions have been eliminated in consolidation.
 
     Profits and losses are generally allocated to the Company and to the
limited partners based upon their respective ownership interests in the
Operating Partnership. Under the terms of the partnership agreement, all costs
incurred by the Company relating to the ownership of its interest in and
operation of the Operating Partnership, including the compensation of its
officers and employees, stock incentive plans, director fees and the costs and
expenses of being a public company, are paid by the Operating Partnership. In
addition, The Irvine Company generally has the right, but not the obligation, to
match on the same terms and conditions any capital contributions made by the
Company and the Operating Partnership based on the pro rata ownership interest
at the time of such contribution.
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities as of
September 30, 1997 and December 31, 1996 and the revenues and expenses for the
three months and nine months ended September 30, 1997 and 1996. Actual results
could differ from those estimates.

                   NOTES TO UNAUDITED CONDENSED CONSOLIDATED
    
                        FINANCIAL STATEMENTS (CONTINUED)
 
     The accompanying unaudited condensed consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and Article 10 of Regulation S-X. Accordingly,
they do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the opinion
of management, all adjustments considered necessary for a fair presentation have
been included. All such adjustments are of a normal, recurring nature. Operating
results for the nine months ended September 30, 1997 are not necessarily
indicative of the results that may be expected for the year ending December 31,
1997. These unaudited condensed financial statements should be read in
conjunction with the Consolidated Financial Statements and notes thereto of the
Operating Partnership included in this Prospectus and Registration Statement.
 
NOTE 3 -- MORTGAGES AND NOTES PAYABLE
 
     Line of Credit: In June 1997, the Operating Partnership renewed its $250
million unsecured revolving credit facility. The credit facility has a term of
three years and currently bears interest at LIBOR plus 0.70% or prime. The
credit facility provides for the borrowing interest rates to be adjusted up or
down reflecting credit ratings on the Operating Partnership's senior unsecured
long-term indebtedness. Under the credit facility, the Operating Partnership is
able to borrow funds from the participating banks through a competitive bid
process to obtain a lower interest rate. At September 30, 1997, outstanding
borrowings under the credit facility priced on a competitive bid basis were $70
million at an average interest spread of 0.46% over LIBOR. This revolving credit
facility, which is guaranteed by the Company, is available to finance the
Operating Partnership's ongoing rental property development program and for
general working capital needs. The Company and the Operating Partnership must
comply with certain affirmative and negative covenants, including limitations on
distributions, and the maintenance of certain net worth, cash flow and financial
ratios. At September 30, 1997 the Company and the Operating Partnership were in
compliance with all of these covenants. As of September 30, 1997, $135 million
was outstanding and $115 million was available under the line of credit.
 
     Shelf Registration Statements: On May 14, 1997 the Company filed a shelf
registration statement with the Securities and Exchange Commission providing for
the issuance from time to time of up to $350 million of common stock, preferred
stock, debt securities, and warrants to purchase common stock, preferred stock
and debt securities. This registration statement replaced the Company's previous
registration statement. The Company plans to use the proceeds raised from any
securities issued under its shelf registration statement for general corporate
purposes, including the development of new apartment communities, acquisitions
and the repayment of existing debt. Availability under the Company's shelf
registration statement was $350 million at September 30, 1997. Concurrently, the
Operating Partnership filed a shelf registration statement with the Securities
and Exchange Commission providing for the issuance from time to time of up to
$350 million of debt securities. The Operating Partnership plans to use the
proceeds raised from any securities issued under its shelf registration
statement for general corporate purposes, including the development of new
apartment communities, acquisitions and the repayment of existing debt.
Availability under the Operating Partnership's shelf registration statement was
$350 million at September 30, 1997.
 
     Subsequent Event: On October 1, 1997 the Operating Partnership issued $100
million aggregate principal amount of 7% senior unsecured notes (the "Notes")
pursuant to its shelf registration statement. The Notes are due on October 1,
2007 and were priced at 99.21% to yield 7.10%, or 99 basis points over the rate
on U.S. Treasury securities with comparable maturity on the date such rate was
set. Net proceeds from the offering of $98.3 million were used to repay
indebtedness under the Operating Partnership's revolving credit facility, which
was used to finance The Villas of Renaissance acquisition (see Note 6).

partnership agreement, purchased 1.39 million additional limited partnership
units at $26.06 per unit (which is equal to the public offering price of the
common stock less an amount equivalent to the underwriting discount) which are
exchangeable for common stock on a one for one basis, subject to adjustment and
certain limitations. The proceeds from the two transactions totaled $66 million
and were used to repay all indebtedness then outstanding under the revolving
line of credit, and for general corporate purposes, including ongoing
development activities on and off the Irvine Ranch.
 
     The Operating Partnership paid cash distributions of $0.365 per partnership
unit on February 28 and May 30, 1997 and $0.375 per partnership unit on August
29, 1997. On October 23, 1997 the Operating Partnership declared a cash dividend
of $0.375 per partnership unit that is payable on November 26, 1997. During the
first and second quarters of 1996, the Operating Partnership paid a cash
dividend of $0.355 per partnership unit and $0.365 per partnership unit during
the third quarter of 1996.
 
     As of September 30, 1997 the Company had $350 million of availability under
its shelf registration statement, which provides for the issuance from time to
time of common stock, preferred stock, debt securities, and warrants to purchase
common stock, preferred stock and debt securities (see Note 3).
 
     The computation of primary earnings per partnership unit for the Operating
Partnership is based on a weighted average of 43,920,321 and 43,349,958 units of
partnership interest outstanding during the three and nine months ended
September 30, 1997, respectively.

NOTE 5 -- ACQUISITION OF THOMPSON RESIDENTIAL ASSETS
 
     On February 4, 1997, the Operating Partnership acquired for $2 million the
assets of Thompson Residential Company, Inc. ("TRC"), a privately held, Northern
California-based multifamily development company. Included in the purchase were
options to purchase three development sites located in Northern California's
Silicon Valley. The purchase price was paid by the issuance of 74,523 limited
partnership units in the Operating Partnership, exchangeable for common stock of
the Company, with the price per unit of $26.838 which was based on the average
closing price of the Company's common stock for the 10 trading days preceding
the acquisition's closing date. In addition, TRC may be paid up to an additional
$2 million in cash or limited partnership units if the apartment community (The
Hamptons) achieves certain performance targets. The three senior real estate
executives at TRC have also joined the Company with primary responsibility for
the Company's operations outside of the Irvine Ranch.

NOTE 6 -- ACQUISITION OF THE VILLAS OF RENAISSANCE
 
     On June 30, 1997 the Operating Partnership acquired a 923-unit apartment
community located in the La Jolla region of north San Diego County from an
unrelated third party for $127.0 million. $118.0 million of the purchase price
was funded by borrowings under the Operating Partnership's $250 million
unsecured line of credit (see Note 3) and $9.0 million was funded from cash on
hand. A more detailed description of the transaction is described in the
Company's and the Operating Partnership's Current Report on Form 8-K filed with
the Securities Exchange Commission on July 15, 1997, as amended on July 23,
1997.
 
NOTE 7 -- CERTAIN TRANSACTIONS WITH RELATED PARTIES
 
     Substantially all costs incurred by the Company are borne by the Operating
Partnership. Included in general and administrative expenses are charges from
The Irvine Company pursuant to an administrative services agreement covering
services for risk management, income taxes and other services of $95,000 and
$80,000 for the nine months ended September 30, 1997 and 1996, respectively. The
Irvine Company and the Operating Partnership jointly purchase employee health
care insurance and property and casualty insurance. In addition, the Operating
Partnership incurred rent totaling $264,000 and $233,000 for the nine months
ended September 30, 1997 and 1996, respectively, related to leases with The
Irvine Company that expire at the end of 1997 and 1998. For the nine months
ended September 30, 1997 The Irvine Company contributed $568,000 in connection
with partnership unit and stock issuances under the dividend reinvestment and
additional cash investment plan.
 
     On February 10, 1997, the Operating Partnership acquired a land site for
$8.4 million from The Irvine Company for the development of 316 rental units
pursuant to the Land Rights Agreement between the Operating Partnership and The
Irvine Company. The Company's board committee of independent directors approved
the purchase in accordance with the Land Rights Agreement. The purchase price
was paid through the issuance of 313,439 additional limited partnership units in
the Operating Partnership to The Irvine Company. Pursuant to the terms of the
acquisition, a portion of the limited partnership units in the Operating
Partnership are subject to refund if the apartment community developed on the
site does not achieve a 10% unleveraged return on costs for the first twelve
months following stabilized occupancy.
 
     On October 21, 1997, the Operating Partnership acquired a land site for
$5.7 million from The Irvine Company for the development of 196 rental units
pursuant to the Land Rights Agreement. The Company's board committee of
independent directors approved the purchase in accordance with the Land Rights
Agreement. The purchase price was paid through the issuance of 179,433
additional limited partnership units in the Operating Partnership to The Irvine
Company. Pursuant to the terms of the acquisition, a portion of the limited
partnership units in the Operating Partnership are subject to refund if the
apartment community developed on the site does not achieve a 10% unleveraged
return on costs for the first twelve months following stabilized occupancy.
 
     Concurrent with the Company's common stock offering on February 20, 1997
(see Note 4), The Irvine Company, pursuant to its rights under the partnership
agreement, purchased 1.39 million limited partnership units at a price equal to
the public offering price of $26.06 per unit (which is equal to the public
offering price of the common stock less an amount equivalent to the underwriting
discount) which are exchangeable for common stock on a one for one basis,
subject to adjustment and certain limitations.
 
     One of the Company's directors is chairman of a bank which participates in
the Company's line of credit. Based on the bank's percentage participation in
the credit facility, the Operating Partnership estimates that the amount of
interest and fees paid to the bank totaled $271,000 and $196,000 in the first
nine months of 1997 and the three months ended September 30, 1997, respectively.
Interest and fees for the corresponding periods in 1996 were $231,000 and
$61,000, respectively.

       NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENTS OF OPERATIONS
    
   
                             (DOLLARS IN THOUSANDS)
    
 
   
NOTE 1 -- BASIS OF PRESENTATION
    
 
   
     Irvine Apartment Communities, L.P. (the "Operating Partnership") acquired a
923-unit apartment community known as The Villas of Renaissance (the "Property")
located in La Jolla, California on June 30, 1997.
    
 
   
     The pro forma consolidated statements of operations of the Operating
Partnership are unaudited and have been prepared based on the historical
financial statements of the Operating Partnership for the nine months ended
September 30, 1997 and the year ended December 31, 1996.
    
 
   
     The unaudited pro forma consolidated statement of operations for the nine
months ended September 30, 1997 has been prepared based on the historical
operations of the Operating Partnership for such period as if the acquisition of
the Property occurred at the beginning of the period presented. As the Property
was acquired on June 30, 1996, the results of operations of the Property after
June 30, 1996 are included in the historical operations of the Operating
Partnership and accordingly are not reflected in the pro forma adjustments. The
unaudited pro forma consolidated statement of operations for the year ended
December 31, 1996 has been prepared based on the historical operations of the
Operating Partnership for 1996 as if the acquisition of the Property occurred as
of the beginning of the period. In management's opinion, all adjustments
necessary to reflect the effect of the acquisition of the Property have been
made in the pro forma financial statements.
    
 
   
     The pro forma information is not necessarily indicative of what the
Operating Partnership's results of operations would have been if the acquisition
of the Property had occurred at the beginning of the periods presented, nor does
it purport to project the Operating Partnership's results of operations at any
future date or for any future period. In addition, the historical operating
results for the nine months ended September 30, 1997 are not necessarily
indicative of the results to be obtained by the Operating Partnership for the
year ending December 31, 1997. The following information should be read in
conjunction with Management's Discussion and Analysis of Financial Condition and
Results of Operations and the financial statements included in this Registration
Statement.
    
 
   
NOTE 2 -- PRO FORMA ADJUSTMENTS
    
 
   
(a) Increase in rental income and other income reflects the operations of the
     Property for the period indicated prior to the acquisition by the Operating
     Partnership.
    
 
   
(b) Increase in property expenses reflects the operations of the Property for
     the period indicated prior to the acquisition by the Operating Partnership
     reduced for the estimated savings in property and liability insurance
     expense in the amount of $134 for the year ended December 31, 1996 and $28
     for the nine months ended September 30, 1997. It is the opinion of
     management that the Property is adequately covered by insurance.
    
 
   
(c) Increase in real estate taxes for the period indicated prior to the
     acquisition by the Operating Partnership based on an estimated increase in
     the assessed value of the Property resulting from the purchase. The
     estimated assessed value is $127,000 with an effective annual tax rate of
     1.12%.
    
 
   
(d) Increase in property management fees for the period indicated prior to the
     acquisition by the Operating Partnership based on the negotiated
     independent third party property management contract for the Property in
     the amount of $20 per month.
    
 
   
(e) Reflects additional interest expense for the period indicated prior to the
     acquisition by the Operating Partnership associated with borrowings used to
     finance the acquisition of the Property in the amount of $118,000,
     calculated based on the interest rate in effect at the time of the
     borrowing of 6.69%. A .125% change in the interest rate of the variable
     rate borrowings used to finance the acquisition of the Property

     would change pro forma interest expense by $147 for the year ended December
     31, 1996 and $111 for the nine months ended September 30, 1997.
    
 
   
(f) Represents additional depreciation for the period indicated prior to the
     acquisition by the Operating Partnership computed on a straight line basis
     using (1) estimated remaining useful life of 40 years and the depreciable
     cost basis of the Property ($102,863, excluding land and personal property)
     and (2) estimated seven year useful life for the related personal property
     ($1,500).
    
 
   
(g) Represents the portion of all preceding pro forma adjustments attributable
     to the limited partners in the Operating Partnership based on an average
     ownership interest of 54.51% for the year ended December 31, 1996 and
     54.83% for the six months ended June 30, 1997 (date of acquisition of the
     Property).

To the Partners
    
   
Irvine Apartment Communities, L.P.
    
 
   
     We have audited the accompanying statement of revenues and certain
operating expenses of The Villas of Renaissance (the "Property") for the year
ended December 31, 1996. This financial statement is the responsibility of the
Property's management. Our responsibility is to express an opinion on this
financial statement based on our audit.
    
 
   
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statement is free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
    
 
   
     The accompanying statement of revenues and certain operating expenses was
prepared for the purpose of complying with the rules and regulations of the
Securities and Exchange Commission for inclusion in the Registration Statement
on Form S-11 of IAC Capital Trust and Irvine Apartment Communities, L.P.
(described in Note 1) and is not intended to be a complete presentation of the
Property's revenues and operating expenses.
    
 
   
     In our opinion, the financial statement presents fairly, in all material
respects, the revenues and certain operating expenses of the Property for the
year ended December 31, 1996 in conformity with generally accepted accounting
principles.

NOTE 1 -- BASIS OF PRESENTATION
    
 
   
     The Property, a luxury apartment community consisting of 923 units, common
area improvements, recreational facilities, and amenities located in La Jolla,
California, is in the process of being sold by Aoki Construction (CA) Co., Ltd.,
a California corporation, ("ACCA") to Irvine Apartment Communities, L.P., a
Delaware limited partnership (the "Operating Partnership"). Prior to April 7,
1997, ACCA was a 99.5% general partner and Aoki Pacific Corporation ("APC") was
a .5% general partner in Renaissance Villas Associates, a California general
partnership (the "Partnership"). On April 7, 1997, APC assigned its interest in
the Partnership to ACCA thus making ACCA the sole remaining partner.
    
 
   
     Interest, depreciation and amortization not directly related to the future
operations of the Property have been excluded from the statement of revenues and
certain operating expenses in accordance with Rule 3-14 of Regulation S-X of the
Securities and Exchange Commission. ACCA and APC are not aware of any material
factors relating to the Property that would cause the reported financial
information not to be indicative of future operating results.
    
 
   
     The unaudited statement of revenues and certain operating expenses for the
six months ended June 30, 1997 has been prepared in accordance with the
Partnership's accounting policies applied to the year ended December 31, 1996.
In the opinion of management, all adjustments and eliminations, consisting only
of normal recurring adjustments, necessary to present fairly the statement of
revenues and certain operating expenses of the Property for the six months ended
June 30, 1997, have been included. The results of operations for this interim
period are not necessarily indicative of the results for the full year.

less. Rental revenue is recognized on an accrual basis.

ITEM 34. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Amended and Restated Declaration of Trust (the "Declaration") of the
Trust will provide that no Trustee, affiliate of any Trustee or any officers,
directors, shareholders, members, partners, employees, representatives or agents
of any Trustee or any employee or agent of the Trust or its affiliates (each, an
"Indemnified Person") shall be liable, responsible or accountable in damages or
otherwise to any employee or agent of the Trust or its affiliates, or any
officers, directors, shareholders, employees, representatives or agents of the
Operating Partnership or the Company or their affiliates or to any holders of
Preferred Securities of the Trust for any loss, damage or claim incurred by
reason of any act or omission performed or omitted by such Indemnified Person in
good faith on behalf of the Trust and in a manner such Indemnified Person
reasonably believed to be within the scope of the authority conferred on such
Indemnified Person by the Declaration or by law, except that an Indemnified
Person shall be liable for any such loss, damage or claim incurred by reason of
such Indemnified Person's gross negligence (or, in the case of the Property
Trustee of the Trust, negligence) or willful misconduct with respect to such
acts or omissions. The Declaration also provides that, to the fullest extent
permitted by applicable law, the Operating Partnership and the Company shall
indemnify and hold harmless each Indemnified Person from and against any loss,
damage or claim incurred by such Indemnified Person by reason of any act or
omission performed or omitted by such Indemnified Person in good faith on behalf
of the Trust and in a manner such Indemnified Person reasonably believed to be
within the scope of authority conferred on such Indemnified Person by the
Declaration, except that no Indemnified Person shall
 
                                      II-1
<PAGE>   153
 
be entitled to be indemnified in respect of any loss, damage or claim incurred
by such Indemnified Person by reason of gross negligence (or, in the case of the
Property Trustee of the Trust, negligence) or willful misconduct with respect to
such acts or omissions. The Declaration further provides that to the fullest
extent permitted by applicable law, expenses (including legal fees) incurred by
an Indemnified Person in defending any claim, demand, action, suit or the final
disposition of such claim, demand, action, suit or proceeding shall, from time
to time, be advanced by the Operating Partnership or the Company prior to the
final disposition of such claim, demand, action, suit or proceeding upon receipt
by the Company and the Operating Partnership of an undertaking by or on behalf
of the Indemnified Person to repay such amount if it shall be determined that
the Indemnified Person is not entitled to be indemnified pursuant to the
Declaration.
 
   
     The Second Amended and Restated Agreement of Limited Partnership (the
"Partnership Agreement") of the Operating Partnership will contain provisions
indemnifying the Company and the Company's officers and directors against
certain liabilities. The Partnership Agreement will provide for indemnification
of the Company and the Company's officers and directors to the fullest extent
permitted by law; provided that no indemnification shall be provided (i) for
willful misconduct or a knowing violation of the law or (ii) for any transaction
for which a party seeking indemnification received an improper personal benefit
in violation or breach of any provision of the Partnership Agreement. Such
indemnification will include the advance of expenses. Any indemnification
pursuant to the Partnership Agreement shall be made only out of the assets of
the Operating Partnership, and neither the Company nor any limited partner of
the Operating Partnership shall have any obligation to contribute to the capital
of the Operating Partnership or otherwise provide funds to enable the Operating
Partnership to fund its indemnification obligations. The indemnification
provided by the Partnership Agreement shall be in addition to any other rights
to which a person may be entitled. Any amendment, modification or repeal of the
indemnification provisions of the Partnership Agreement shall be prospective
only, and shall not apply to or have any effect on any right to indemnification
provided thereunder with respect to acts or omissions occurring prior to such
amendment, modification or repeal.
    
 
     In addition, the Company's officers and directors are indemnified under
Maryland law and the Company's Articles of Incorporation. Section 2-418 of the
Maryland General Corporation Law permits the indemnification of directors,
officers, employees and agents of Maryland corporations. ARTICLE EIGHTH of the

ITEM 37. UNDERTAKINGS.
 
   
     The undersigned registrants hereby undertake to provide to the Underwriters
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
    
 
   
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, trustees and controlling
persons of the registrants pursuant to the foregoing provisions or otherwise,
the registrants have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrants of expenses incurred or paid by a director, officer, trustee or
controlling person of the registrants in the successful defense of any action,
suit or proceeding) is asserted by such director, officer, trustee or
controlling person, in connection with the securities being registered
hereunder, the registrants will, unless in the opinion of their counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by them is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.
    
 
   
The undersigned registrants hereby further undertake that:
    
 
   
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrants pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
    
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

        SECTION 1.    Representations and Warranties.

        (a) Representations and Warranties by the Trust, the Operating
Partnership and the Company. Each of the Trust, the Operating Partnership and
the Company, jointly and severally, represents and warrants to each Underwriter
as of the date hereof, as of the Closing Time referred to in Section 2(c)
hereof, and as of each Date of Delivery (if any) referred to in Section 2(b)
hereof, and agrees with each Underwriter, as follows:

               (i) Compliance with Registration Requirements. Each of the
        Registration Statement and any Rule 462(b) Registration Statement has
        become effective under the 1933 Act and no stop order suspending the
        effectiveness of the Registration Statement or any Rule 462(b)
        Registration Statement has been issued under the 1933 Act and no
        proceedings for that purpose have been instituted or are pending or, to
        the knowledge of the Trust, the Operating Partnership or the Company,
        are threatened by the Commission, and any request on the part of the
        Commission for additional information has been complied with.

               At the respective times the Registration Statement, any Rule
        462(b) Registration Statement and any post-effective amendments thereto
        became effective and at the Closing Time (and, if any Option Securities
        are purchased, at the Date of Delivery), the Registration Statement, the
        Rule 462(b) Registration Statement and any amendments and supplements
        thereto complied and will comply in all material respects with the
        requirements of the 1933 Act and the 1933 Act Regulations and did not
        and will not contain an untrue statement of a material fact or omit to
        state a material fact required to be stated therein or necessary to make
        the statements therein not misleading. Neither the Prospectus nor any
        amendments or supplements thereto, at the time the Prospectus or any
        such amendment or supplement was issued and at the Closing Time (and, if
        any Option Securities are purchased, at the Date of Delivery), included
        or will include an untrue statement of a material fact or omitted or
        will omit to state a material fact necessary in order to make the
        statements therein, in the light of the circumstances under which they
        were made, not misleading. If Rule 434 is used, the Trust, the Operating
        Partnership and the Company will comply with the requirements of Rule
        434 and the Prospectus shall not be "materially different", as such term
        is used in Rule 434, from the prospectus included in the Registration
        Statement at the time it became effective. The representations and
        warranties in this subsection shall not apply to statements in or
        omissions from the Registration Statement or Prospectus made in reliance
        upon and in conformity with information furnished to the Trust, the
        Operating Partnership or the Company in writing by any Underwriter
        through Merrill Lynch expressly for use in the Registration Statement or
        Prospectus.

               Each preliminary prospectus and the prospectus filed as part of
        the Registration Statement as originally filed or as part of any
        amendment thereto, or filed pursuant to Rule 424 under the 1933 Act,
        complied when so filed in all material respects with the 1933 Act
        Regulations and each preliminary prospectus and the Prospectus delivered
        to the Underwriters for use in connection with this offering was
        identical to the electronically

                                        4

        transmitted copies thereof filed with the Commission pursuant to EDGAR,
        except to the extent permitted by Regulation S-T.

               (ii) Independent Accountants. The accountants who certified the
        financial statements and supporting schedules included in the
        Registration Statement are independent public accountants as required by
        the 1933 Act and the 1933 Act Regulations.

               (iii) Financial Statements. The historical financial statements
        of the Operating Partnership, and the related notes thereto, included in
        the Registration Statement and the Prospectus present fairly the
        consolidated financial position of the Operating Partnership and its
        Subsidiaries taken as a whole as of the dates indicated and the results
        of operations and the changes in their consolidated cash flows for the
        periods specified; the historical financial statements of the Trust, and
        the related notes thereto, included in the Registration Statement and
        the Prospectus present fairly the financial position of the Trust as of
        the dates indicated; except as otherwise stated in the Registration
        Statement and the Prospectus, said financial statements have been
        prepared in conformity with generally accepted accounting principles
        applied on a consistent basis and comply with the applicable accounting
        requirements of the 1933 Act (including, without limitation, Rule 3-14
        and Rule 3-15 of Regulation S-X promulgated by the Commission), and all
        adjustments necessary for a fair presentation of the results for such
        periods have been made; the supporting schedules included in the
        Registration Statement and the Prospectus present fairly the information
        required to be stated therein; the financial information and data
        included in the Registration Statement and the Prospectus present fairly
        the information included therein and have been prepared on a basis
        consistent with that of the financial statements included in the
        Registration Statement and the Prospectus. Except as reflected or
        disclosed in the financial statements included in the Registration
        Statement or otherwise set forth in the Prospectus, each of the Trust
        and the Operating Partnership is not subject to any material
        indebtedness, obligation or liability, contingent or otherwise.

               (iv) Summaries of Revenue. The historical summaries of revenue
        and certain operating expenses included in the Registration Statement
        and the Prospectus present fairly the revenue and those operating
        expenses included in such summaries of the properties related thereto
        for the periods specified in conformity with generally accepted
        accounting principles; the pro forma consolidated financial statements
        included by incorporation or otherwise in the Registration Statement and
        the Prospectus present fairly the pro forma financial position of the
        Company and its Subsidiaries taken as a whole as of the dates indicated
        and the results of operations for the periods specified; and such pro
        forma financial statements have been prepared in accordance with
        generally accepted accounting principles applied on a basis consistent
        with the audited financial statements of the Operating Partnership and
        its Subsidiaries included by incorporation or otherwise in the
        Registration Statement and the Prospectus, the assumptions on which such
        pro forma financial statements have been prepared were, when such pro
        forma financial statements were prepared, reasonable and are summarized
        in the notes thereto, and any such pro forma financial statements have
        been

                                        5

        prepared, and the pro forma adjustments set forth therein have been
        applied, in accordance with the applicable accounting requirements of
        the 1933 Act (including, without limitation, Regulation S-X promulgated
        by the Commission), and any such pro forma adjustments have been
        properly applied to the historical amounts in the compilation of such
        statements.

               (v) No Material Adverse Change in Business. Since the respective
        dates as of which information is given in the Registration Statement and
        the Prospectus, there has not been any material adverse change in the
        equity or long-term debt of the Trust or of the Operating Partnership
        and its consolidated subsidiaries, or any material adverse change, or
        any development involving a prospective material adverse change, in the
        condition, financial or otherwise, or in the earnings, business or
        operations of the REIT Entities, taken as a whole, otherwise than as set
        forth or contemplated in the Prospectus; and except as set forth or
        contemplated in the Prospectus none of the REIT Entities nor any of
        their Subsidiaries has entered into any transaction or agreement
        (whether or not in the ordinary course of business) material to the REIT
        Entities and their Subsidiaries taken as a whole.

               (vi) Good Standing of the Trust. The Trust has been duly created,
        is validly existing as a statutory business trust in good standing under
        the Business Trust Act of the State of Delaware (the "Delaware Business
        Trust Act") and has the power and authority to own its property and to
        conduct its business as described in the Prospectus; the Trust has
        conducted under Subchapter M of the Internal Revenue Code of 1986, as
        amended (the "Code"), no business to date, and it will conduct no
        business in the future that would be inconsistent with the description
        of the Trust set forth in the Prospectus; for United States Federal
        income tax purposes, the Trust has been and is currently classified as a
        real estate investment trust; the Trust is not a party to or bound by
        any agreement or instrument other than this Agreement, the Amended and
        Restated Declaration of Trust of IAC Capital Trust among the trustees
        named therein (the "Declaration") and the agreements and instruments
        contemplated by the Declaration; the Trust has no liabilities or
        obligations other than those arising out of the transactions
        contemplated by this Agreement and the Declaration and described in the
        Prospectus; and the Trust is not a party to or subject to any action,
        suit or proceeding of any nature.

               (vii) Good Standing of the Operating Partnership and the Property
        Partnership. Each of the Operating Partnership and the Property
        Partnership has been duly formed, is validly existing as a limited
        partnership in good standing under the laws of the jurisdiction of its
        formation, has the power and authority to own its property and to
        conduct its business as described in the Prospectus and is duly
        qualified to transact its business and is in good standing in
        California, which is the only other jurisdiction in which the conduct of
        its business or its ownership or leasing of property requires such
        qualification, except to the extent that the failure to be so qualified
        or be in good standing would not have a material adverse effect on the
        REIT Entities taken as a whole. For United States Federal income tax
        purposes, each of the Operating Partnership and the Property Partnership
        has been and is taxable as a partnership and not as a corporation.

        and is in good standing in each jurisdiction in which the conduct of its
        business or its ownership or leasing of property requires such
        qualification, except to the extent that the failure to be so qualified
        or in good standing would not have a material adverse effect on the REIT
        Entities, taken as a whole; other than the Operating Partnership, the
        Company has no "significant subsidiaries" as defined in Rule 1-02 of
        Regulation S-X promulgated by the Commission (the "Significant

        by reference as exhibits to the Registration Statement that are not
        described, filed or incorporated as required.

               (xix) Title to Property. The Operating Partnership has (whether
        directly or indirectly through the ownership of the Property
        Partnership) good title in fee simple to the Properties and good title
        to all personal property owned as is material to the business of the
        REIT Entities, taken as a whole, in each case free and clear of all
        liens, encumbrances and defects except such as are described in the
        Prospectus or in title policies held by the Operating Partnership or
        such as do not materially affect the value of such property and do not
        interfere with the use made and proposed to be made of such property by
        the REIT Entities; any real property held under lease by any REIT Entity
        is held by it under valid, subsisting, enforceable leases, and no
        default by any REIT Entity has occurred and is continuing thereunder,
        with such exceptions as are not material and do not interfere in any
        material respect with the use made and proposed to be made of such
        property by any REIT Entity; the operation of the buildings, fixtures
        and other improvements located on the Properties as presently conducted
        is not in violation of any applicable building code, zoning ordinance or
        other law or regulation, except where such violation of any applicable
        building code, zoning ordinance or other law or regulation would not,
        singly or in the aggregate, have a material adverse effect on the REIT
        Entities, taken as a whole; neither the Company nor the Operating
        Partnership has received notice of any proposed special assessment or
        any proposed material change in any property tax, zoning or land use
        laws or availability of water for irrigation affecting all or any
        portion of the Properties; there do not exist any material violations of
        any declaration of covenants, conditions and restrictions with respect
        to any of the Properties, nor is there any existing state of facts or
        circumstances or condition or event which could, with the giving of
        notice or passage of time, or both, constitute such a violation; and the
        improvements comprising any portion of the Properties (the
        "Improvements") are free of any and all material physical, mechanical,
        structural, design and construction defects and the Improvements
        (including, without limitation, all water, electric, sewer, plumbing,
        heating, ventilation, gas and air conditioning

                                       10

<PAGE>   14



        servicing the Improvements) are in good condition and proper working
        order and are free of material defects.

               (xx) Insurance. The REIT Entities have and will maintain
        liability, property, casualty and other insurance policies, with respect
        to each of the Properties, insuring them against the risks of loss
        (other than with respect to loss from earthquakes) arising out of or
        related to their businesses, in an amount and on such terms as is
        adequate and appropriate for such businesses.

               (xxi) Investment Company Act. None of the Trust, the Operating
        Partnership nor the Company is, and upon the issuance and sale of the
        Securities as herein contemplated and the application of the net
        proceeds therefrom as described in the Prospectus will be, an
        "investment company" or an entity "controlled" by an "investment
        company" as such terms are defined in the Investment Company Act of
        1940, as amended (the "1940 Act").

               (xxii) Environmental Laws. The Properties are, to the best
        knowledge of the REIT Entities, in compliance with any and all
        applicable foreign, federal, state and local laws and regulations
        relating to the protection of human health and safety, the environment
        or hazardous or toxic substances or wastes, pollutants or contaminants
        ("Environmental Laws"), and the REIT Entities (i) have received all
        permits, licenses or other approvals required of them under applicable
        Environmental Laws to conduct their respective businesses and (ii) are
        in compliance with all terms and conditions of any such permit, license
        or approval, except where such noncompliance with Environmental Laws,
        failure to receive required permits, licenses or other approvals or
        failure to comply with the terms and conditions of such permits,
        licenses or approvals would not, singly or in the aggregate, have a
        material adverse effect on the REIT Entities, taken as a whole.

               (xxiii) Environmental Liabilities. To the best knowledge of the
        Company and the Operating Partnership, there are no costs and
        liabilities associated with Environmental Laws except as disclosed in
        the Registration Statement, which would, singly or in the aggregate,
        have a material adverse effect on the REIT Entities, taken as a whole.

               (xxiv) REIT Status. Each of the Trust and the Company are
        organized in conformity with the requirements for qualification as a
        real estate investment trust under the Code, and its method of operation
        enables it to meet the requirements for taxation as a real estate
        investment trust under the Code.

               (xxv) Partnership Status. Each of the Operating Partnership and
        the Property Partnership is organized in conformity with the
        requirements for qualification as a partnership under the Code, and its
        method of operation enables it to meet the requirements for taxation as
        a partnership under the Code. Neither the Operating Partnership nor the
        Property Partnership are subject to taxation as a corporation.

               (xxvi) Operating Partnership. All of the OP Units outstanding
        prior to issuance of the Series A Preferred L.P. Units have been validly
        issued and are validly owned, directly or indirectly,

                                       11

<PAGE>   15



        in the percentage amounts set forth in the Prospectus by the Company and
        The Irvine Company and affiliates of The Irvine Company; the OP Units
        owned, directly or indirectly, by the Company are owned free and clear
        of any security interest, mortgage, pledge, lien, encumbrance, claim or
        equity (each of the foregoing a "Lien"). The Company is the sole general
        partner of the Operating Partnership.

               (xxvii) Property Partnership. All of the partnership interests of
        the Property Partnership have been validly issued and are owned of
        record by the Operating Partnership and a third party; the partnership
        interests of the Property Partnership owned of record by the Operating
        Partnership are owned free and clear of all Liens.

        (b) Officer's Certificates. Any certificate signed by any Trustee of the
Trust, any partner of the Operating Partnership, any officer of the Company or
any of their subsidiaries delivered to the Representatives or to counsel for the
Underwriters shall be deemed a representation and warranty by the Trust, the
Operating Partnership or the Company, respectively, to each Underwriter as to
the matters covered thereby.

        SECTION 2.  Sale and Delivery to Underwriters; Closing.

        (a) Initial Securities. On the basis of the representations and
warranties herein contained and subject to the terms and conditions herein set
forth, the Trust, the Operating Partnership and the Company agree that the Trust
shall sell to each Underwriter, severally and not jointly, and each Underwriter,
severally and not jointly, agrees to purchase from the Trust, at the price per
security set forth in Schedule B, the number of Initial Securities set forth in
Schedule A opposite the name of such Underwriter, plus any additional number of
Initial Securities which such Underwriter may become obligated to purchase
pursuant to the provisions of Section 10 hereof.

        (b) Option Securities. In addition, on the basis of the representations
and warranties herein contained and subject to the terms and conditions herein
set forth, the Trust hereby grants an option to the Underwriters, severally and
not jointly, to purchase up to an additional 780,000 Securities at the price per
security set forth in Schedule B. The option hereby granted will expire 30 days
after the date hereof and may be exercised in whole or in part from time to time
only for the purpose of covering over-allotments which may be made in connection
with the offering and distribution of the Initial Securities upon notice by the
Representatives to the Trust setting forth the number of Option Securities as to
which the several Underwriters are then exercising the option and the time and
date of payment and delivery for such Option Securities. Any such time and date
of delivery (a "Date of Delivery") shall be determined by the Representatives,
but shall not be later than seven full business days after the exercise of said
option, nor in any event prior to the Closing Time, as hereinafter defined. If
the option is exercised as to all or any portion of the Option Securities, each
of the Underwriters, acting severally and not jointly, will purchase that
proportion of the total number of Option Securities then being purchased which
the number of Initial Securities set forth in Schedule A opposite the name of
such Underwriter bears to the total number of Initial Securities, subject in
each case to such adjustments as the Representatives in their discretion shall
make to eliminate any sales or purchases of fractional units.

                                       12

<PAGE>   16



        (c) Commission. The Operating Partnership agrees to pay to the
Representatives, for the accounts of the several Underwriters, a commission set
forth in Schedule B as compensation to the Underwriters for their commitments
under this Agreement.

        (d) Payment. Payment of the purchase price for, and delivery of
certificates for, the Initial Securities shall be made at the offices of
Skadden, Arps, Slate, Meagher & Flom LLP, 300 South Grand Avenue, Los Angeles,
California 90071, or at such other place as shall be agreed upon by the
Representatives and the Trust, at 9:30 A.M. (Eastern time) on the third (fourth,
if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business
day after the date hereof (unless postponed in accordance with the provisions of
Section 10), or such other time not later than ten business days after such date
as shall be agreed upon by the Representatives and the Trust (such time and date
of payment and delivery being herein called "Closing Time").

        In addition, in the event that any or all of the Option Securities are
purchased by the Underwriters, payment of the purchase price for, and delivery
of certificates for, such Option Securities shall be made at the above-mentioned
offices, or at such other place as shall be agreed upon by the Representatives
and the Trust, on each Date of Delivery as specified in the notice from the
Representatives to the Trust. Payment shall be made to the Trust by wire
transfer of immediately available funds to a bank account designated by the
Trust, against delivery to the Representatives for the respective accounts of
the Underwriters of certificates for the Securities to be purchased by them. It
is understood that each Underwriter has authorized the Representatives, for its
account, to accept delivery of, receipt for, and make payment of the purchase
price for, the Initial Securities and the Option Securities, if any, which it
has agreed to purchase. Merrill Lynch, individually and not as representative of
the Underwriters, may (but shall not be obligated to) make payment of the
purchase price for the Initial Securities or the Option Securities, if any, to
be purchased by any Underwriter whose funds have not been received by the
Closing Time or the relevant Date of Delivery, as the case may be, but such
payment shall not relieve such Underwriter from its obligations hereunder.

        (e) Denominations; Registration. Certificates for the Initial Securities
and the Option Securities, if any, shall be in such denominations and registered
in such names as the Representatives may request in writing at least one full
business day before the Closing Time or the relevant Date of Delivery, as the
case may be. The certificates for the Initial Securities and the Option
Securities, if any, will be made available for examination and packaging by the
Representatives in The City of New York not later than 10:00 A.M. (Eastern time)
on the business day prior to the Closing Time or the relevant Date of Delivery,
as the case may be.


        SECTION 3. Covenants of the Trust and the Operating Partnership. The
Trust and the Operating Partnership covenant with each Underwriter as follows:

               (a) Compliance with Securities Regulations and Commission
        Requests. The Trust and the Operating Partnership, subject to Section
        3(b), will comply with the requirements of Rule 430A or Rule 434, as
        applicable, and will notify the Representatives immediately, and confirm
        the

                                       13

<PAGE>   17



        notice in writing, (i) when any post-effective amendment to the
        Registration Statement shall become effective, or any supplement to the
        Prospectus or any amended Prospectus shall have been filed, (ii) of the
        receipt of any comments from the Commission, (iii) of any request by the
        Commission for any amendment to the Registration Statement or any
        amendment or supplement to the Prospectus or for additional information,
        and (iv) of the issuance by the Commission of any stop order suspending
        the effectiveness of the Registration Statement or of any order
        preventing or suspending the use of any preliminary prospectus, or of
        the suspension of the qualification of the Securities for offering or
        sale in any jurisdiction, or of the initiation or threatening of any
        proceedings for any of such purposes. The Trust and the Operating
        Partnership will promptly effect the filings necessary pursuant to Rule
        424(b) and will take such steps as they deem necessary to ascertain
        promptly whether the form of prospectus transmitted for filing under
        Rule 424(b) was received for filing by the Commission and, in the event
        that it was not, they will promptly file such prospectus. The Trust and
        the Operating Partnership will make every reasonable effort to prevent
        the issuance of any stop order and, if any stop order is issued, to
        obtain the lifting thereof at the earliest possible moment.

               (b) Filing of Amendments. The Trust and the Operating Partnership
        will give the Representatives notice of their intention to file or
        prepare any amendment to the Registration Statement (including any
        filing under Rule 462(b)), any Term Sheet or any amendment, supplement
        or revision to either the prospectus included in the Registration
        Statement at the time it became effective or to the Prospectus, will
        furnish the Representatives with copies of any such documents a
        reasonable amount of time prior to such proposed filing or use, as the
        case may be, and will not file or use any such document to which the
        Representatives or counsel for the Underwriters shall reasonably object.

               (c) Delivery of Registration Statements. The Trust and the
        Operating Partnership have furnished or will deliver to the
        Representatives and counsel for the Underwriters, without charge, signed
        copies of the Registration Statement as originally filed and of each
        amendment thereto (including exhibits filed therewith or incorporated by
        reference therein) and signed copies of all consents and certificates of
        experts, and will also deliver to the Representatives, without charge, a
        conformed copy of the Registration Statement as originally filed and of
        each amendment thereto (without exhibits) for each of the Underwriters.
        The copies of the Registration Statement and each amendment thereto
        furnished to the Underwriters will be identical to the electronically
        transmitted copies thereof filed with the Commission pursuant to EDGAR,
        except to the extent permitted by Regulation S-T.

               (d) Delivery of Prospectuses. The Trust and the Operating
        Partnership have delivered to each Underwriter, without charge, as many
        copies of each preliminary prospectus as such Underwriter reasonably
        requested, and the Trust and the Operating Partnership hereby consent to
        the use of such copies for purposes permitted by the 1933 Act. The Trust
        and the Operating Partnership will furnish to each Underwriter, without
        charge, during the period when the Prospectus is required to be
        delivered under the 1933 Act or the 1934 Act, such number of copies of
        the Prospectus (as amended or supplemented) as such Underwriter may
        reasonably request.

                                       14

<PAGE>   18



        The Prospectus and any amendments or supplements thereto furnished to
        the Underwriters will be identical to the electronically transmitted
        copies thereof filed with the Commission pursuant to EDGAR, except to
        the extent permitted by Regulation S-T.

               (e) Continued Compliance with Securities Laws. The Trust and the
        Operating Partnership will comply with the 1933 Act and the 1933 Act
        Regulations so as to permit the completion of the distribution of the
        Securities as contemplated in this Agreement and in the Prospectus. If
        at any time when a prospectus is required by the 1933 Act to be
        delivered in connection with sales of the Securities, any event shall
        occur or condition shall exist as a result of which it is necessary, in
        the opinion of counsel for the Underwriters or for the Trust and the
        Operating Partnership, to amend the Registration Statement or amend or
        supplement the Prospectus in order that the Prospectus will not include
        any untrue statements of a material fact or omit to state a material
        fact necessary in order to make the statements therein not misleading in
        the light of the circumstances existing at the time it is delivered to a
        purchaser, or if it shall be necessary, in the opinion of such counsel,
        at any such time to amend the Registration Statement or amend or
        supplement the Prospectus in order to comply with the requirements of
        the 1933 Act or the 1933 Act Regulations, the Trust and the Operating
        Partnership will promptly prepare and file with the Commission, subject
        to Section 3(b), such amendment or supplement as may be necessary to
        correct such statement or omission or to make the Registration Statement
        or the Prospectus comply with such requirements, and the Trust and the
        Operating Partnership will furnish to the Underwriters such number of
        copies of such amendment or supplement as the Underwriters may
        reasonably request.

               (f) Blue Sky Qualifications. The Trust and the Operating
        Partnership will use their respective best efforts, in cooperation with
        the Underwriters, to qualify the Securities for offering and sale under
        the applicable securities laws of such states and other jurisdictions as
        the Representatives may designate and to maintain such qualifications in
        effect for a period of not less than one year from the later of the
        effective date of the Registration Statement and any Rule 462(b)
        Registration Statement; provided, however, that the Trust or the
        Operating Partnership shall not be obligated to file any general consent
        to service of process or to qualify as a foreign trust or partnership,
        as the case may be, or as a dealer in securities in any jurisdiction in
        which it is not so qualified or to subject itself to taxation in respect
        of doing business in any jurisdiction in which it is not otherwise so
        subject. In each jurisdiction in which the Securities have been so
        qualified, the Trust and the Operating Partnership will file such
        statements and reports as may be required by the laws of such
        jurisdiction to continue such qualification in effect for a period of
        not less than one year from the effective date of the Registration
        Statement and any Rule 462(b) Registration Statement.

               (g) Rule 158. The Trust and the Operating Partnership will timely
        file such reports pursuant to the 1934 Act as are necessary in order to
        make generally available to their securityholders as soon as practicable
        an earnings statement for the purposes of, and to provide the benefits
        contemplated by, the last paragraph of Section 11(a) of the 1933 Act.


                                       15

               (h) Use of Proceeds. The Trust will use the net proceeds received
        by it from the sale of the Securities in the manner specified in the
        Prospectus under "Use of Proceeds".

               (i) Listing. The Trust and the Operating Partnership will their
        respective best efforts to effect the listing of the Securities on the
        New York Stock Exchange.

               (j) Restriction on Sale of Securities. During a period of 90 days
        from the date of this Agreement, the Trust, the Operating Partnership
        and the Company will not, without the prior written consent of Merrill
        Lynch, (i) directly or indirectly, offer, pledge, sell, contract to
        sell, sell any option or contract to purchase, purchase any option or
        contract to sell, grant any option, right or warrant to purchase or
        otherwise transfer or dispose of (x) any securities of the Trust, (y)
        any preferred limited partnership interests or any other security of the
        Operating Partnership that is substantially similar to the Series A
        Preferred L.P. Units, or any securities convertible into or exercisable
        or exchangeable for any of the foregoing or file any registration
        statement under the 1933 Act with respect to any of the foregoing or
        (ii) enter into any swap or any other agreement or any transaction that
        transfers, in whole or in part, directly or indirectly, the economic
        consequences of ownership of securities of the Trust or preferred
        limited partnership interests, whether any such swap or transaction
        described in clause (i) and (ii) above is to be settled by delivery of
        securities of the Trust, preferred limited partnership interests or such
        other securities, in cash or otherwise. The foregoing sentence shall not
        apply to the Securities to be sold hereunder, the issuance and sale of
        the Common Securities described herein and the issuance and sale of the
        Series A Preferred L.P. Units described herein.

               (k) REIT Requirements. The Trust will continue to use its best
        efforts to continue to meet the requirements to qualify as a REIT under
        the Code, except as otherwise set forth in the Declaration.

               (l) Reporting Requirements. The Trust and the Operating
        Partnership, during the period when the Prospectus is required to be
        delivered under the 1933 Act or the 1934 Act, will file all documents
        required to be filed with the Commission pursuant to the 1934 Act within
        the time periods required by the 1934 Act and the rules and regulations
        of the Commission thereunder.

               (m) Compliance with NASD Rules. The Company hereby agrees that it
        will use its best efforts to ensure that the Reserved Securities will be
        restricted as required by the NASD or the NASD rules from sale,
        transfer, assignment, pledge or hypothecation for a period of three
        months following the date of this Agreement. The Underwriters will
        notify the Company as to which persons will need to be so restricted. At
        the request of the Underwriters, the Company will direct the transfer
        agent to place a stop transfer restriction upon such securities for such
        period of time. Should the Company release, or seek to release, from
        such restrictions any of the Reserved Securities, the Company agrees to
        reimburse the Underwriters for any reasonable expenses (including,
        without limitation, legal expenses) they incur in connection with such
        release.

        dated as of the Closing Time, of Emmet, Marvin & Martin, special counsel

        satisfactory to counsel for the Underwriters, together with signed or
        reproduced copies of such letter for each of the other Underwriters with
        respect to the matters set forth in Exhibit C and to such further effect

        Securities and the Preferred L.P. Units"), (xxii), (xxiv), (xxv) and the
        penultimate paragraph of Exhibit A hereto. In giving such opinion such
        counsel may rely, as to all matters governed by the laws of
        jurisdictions other than the law of the State of New York and the
        federal law of the United States, the Revised Uniform Limited
        Partnership Act of the State of Delaware, and the Business Trust Act of
        the State of Delaware, upon the opinions of counsel satisfactory to the
        Representatives. Such counsel may also state that, insofar as such
        opinion involves factual matters, they have relied, to the extent they
        deem proper, upon certificates of officers of the Trust or the
        Partnership and their subsidiaries and certificates of public officials.

        enterprise, whether or not arising in the ordinary course of business,
        and the Representatives shall have received a certificate of an
        executive officer of the Company, in its individual capacity and in its

        material adverse change, (ii) the representations and warranties in
        Section 1(a) hereof are true and correct with the same force and effect
        as though expressly made at and as of Closing Time, and (iii) the Trust,
        the Operating Partnership and the Company have complied with all
        agreements and satisfied all conditions on their parts to be performed
        or satisfied at or prior to Closing Time.

               (i) Accountant's Comfort Letter. At the time of the execution of
        this Agreement, the Representatives shall have received from Ernst &

        be rated at least Ba1 by Moody's Investors Service and BBB- by Standard
        & Poor's Ratings Group, a division of McGraw-Hill, Inc., and the Trust
        shall have delivered to the Representatives a letter dated the Closing
        Time, from each such rating agency, or other evidence satisfactory to
        the Representatives, confirming that the Securities have such ratings;
        and since the date of this Agreement, there shall not have occurred a
        downgrading in the rating assigned to the Securities or any of the
        Trust's, the Operating Partnership's or the Company's other securities
        by any "nationally recognized statistical rating agency," as that term
        is defined by the Commission for purposes of Rule 436(g)(2) under the
        1933 Act, and no such organization shall have publicly announced that it
        has under surveillance or review its rating of the Securities or any of
        the Trust's, the Operating Partnership's or the Company's other
        securities.

        that the Underwriters exercise their option provided in Section 2(b)
        hereof to purchase all or any portion of the Option Securities, the
        representations and warranties of the Trust contained herein and the
        statements in any certificates furnished by the Trust or any subsidiary
        of the Trust hereunder shall be true and correct as of each Date of
        Delivery and, at the relevant Date of Delivery, the Representatives
        shall have received:

               (i) Officers' Certificate. A certificate, dated such Date of

               effect as the opinion required by Section 5(d) hereof.

               (iii) Opinion of Maryland Counsel for the Company. The favorable
               opinion of Piper & Marbury L.L.P., Maryland counsel for the
               Company, in form and substance satisfactory to counsel for the
               Underwriters, dated such Date of Delivery, relating to the Option

               opinion of Emmet Marvin & Martin, special counsel for the
               Property Trustee, in form and substance satisfactory to counsel
               for the Underwriters, dated such Date of Delivery, relating to
               the Option Securities to be purchased on such Date of Delivery
               and otherwise to the same effect as the opinion required by

               (v) Opinion of Counsel for Underwriters. The favorable opinion of
               Skadden, Arps, Slate, Meagher & Flom LLP, counsel for the

               to the same effect as the opinion required by Section 5(g)
               hereof.

               (vi) Bring-down Comfort Letter. A letter from Ernst & Young LLP
               in form and substance satisfactory to the Representatives and

               substance as the letter furnished to the Representatives pursuant
               to Section 5(i) hereof, except that the "specified date" in the

                                       21

               (p) Termination of Agreement. If any condition specified in this
        Section shall not have been fulfilled when and as required to be
        fulfilled, this Agreement, or, in the case of any condition to the
        purchase of Option Securities on a Date of Delivery which is after the
        Closing Time, the obligations of the several Underwriters to purchase
        the relevant Option Securities, may be terminated by the Representatives
        by notice to the Trust and the Operating Partnership at any time at or
        prior to Closing Time or such Date of Delivery, as the case may be, and
        such termination shall be without liability of any party to any other
        party except as provided in Section 4 and except that Sections 1, 6, 7
        and 8 shall survive any such termination and remain in full force and
        effect.

        SECTION 6. Indemnification.

               (a) Indemnification of Underwriters. The Operating Partnership
        and the Company, jointly and severally, hereby agree to indemnify and
        hold harmless each Underwriter and each person, if any, who controls any
        Underwriter within the meaning of either Section 15 of the 1933 Act or
        Section 20 of the 1934 Act, from and against any and all losses, claims,
        damages and liabilities (including without limitation the legal fees and
        other expenses incurred in connection with any suit, action or
        proceeding or any claim asserted) caused by any untrue statement or
        alleged untrue statement of a material fact contained in the
        Registration Statement or the Prospectus (as amended or supplemented if
        the Trust shall have furnished any amendments or supplements thereto) or
        any preliminary prospectus, or caused by any omission or alleged
        omission to state therein a material fact required to be stated therein
        or necessary to make the statements therein not misleading, except
        insofar as such losses, claims, damages or liabilities are caused by any
        untrue statement or omission or alleged untrue statement or omission
        made in reliance upon and in conformity with information relating to any
        Underwriter furnished to the Trust, the Operating Partnership and/or the
        Company in writing by such Underwriter through the Representatives
        expressly for use therein, provided, however, that the foregoing
        indemnity agreement with respect to any preliminary prospectus shall not
        inure to the benefit of any Underwriter from whom the person asserting
        any such losses, claims, damages or liabilities purchased Securities, or
        any person controlling such Underwriter, if a copy of the Prospectus (as
        then amended or supplemented if the Trust shall have furnished any
        amendments or supplements thereto) was not sent or given by or on behalf
        of such Underwriter to such person, if required by law so to have been
        delivered, at or prior to the written confirmation of the sale of the
        Securities to such person, and if the Prospectus (as so amended or
        supplemented) would have cured the defect giving rise to such losses,
        claims, damages or liabilities, unless such failure is the result of
        noncompliance by the Trust with Sections 3(c) and (d) hereof.

               (b) Indemnification of Trust, the Operating Partnership, the
        Company, Trustees, Directors and Officers. Each Underwriter agrees,
        severally and not jointly, to indemnify and hold harmless the Trust, the
        Operating Partnership, the Company and the Trustees, directors, each of
        the officers of the Company who signs the Registration Statement and
        each person who controls the Trust, the Operating Partnership or the
        Company within the meaning of Section 15 of the 1933 Act or Section 20
        of the 1934 Act, to the same extent as the foregoing indemnity from the
        Trust, the Operating Partnership and the Company to each Underwriter,
        but only with reference to

                                       22

<PAGE>   26



        information relating to such Underwriter furnished to the Trust, the
        Operating Partnership or the Company in writing by such Underwriter
        through the Representatives expressly for use in the Registration
        Statement, the Prospectus, any amendment or supplement thereto, or any
        preliminary prospectus. For purposes of this Section 6 and Section 4(a),
        the only written information furnished by the Underwriters to the Trust,
        the Operating Partnership and the Company expressly for use in the
        Registration Statement and the Prospectus is (a) the information in the
        last paragraph on the cover page of the Prospectus, (b) the information
        regarding stabilization on the inside front cover page of the Prospectus
        and (c) the information in the [third and sixth paragraphs and the
        second sentence of the fourth paragraph] under the caption
        "Underwriting" in the Prospectus.

               (c) Actions against Parties; Notification. If any suit, action,
        proceeding (including any governmental or regulatory investigation),
        claim or demand shall be brought or asserted against any person in
        respect of which indemnity may be sought pursuant to either of the two
        preceding paragraphs, such person (the "Indemnified Person") shall
        promptly notify the person against whom such indemnity may be sought
        (the "Indemnifying Person") in writing, and the Indemnifying Person,
        upon request of the Indemnified Person, shall retain counsel reasonably
        satisfactory to the Indemnified Person to represent the Indemnified
        Person and any others the Indemnifying Person may designate in such
        proceeding and shall pay the fees and expenses of such counsel related
        to such proceeding. In any such proceeding, any Indemnified Person shall
        have the right to retain its own counsel, but the fees and expenses of
        such counsel shall be at the expense of such Indemnified Person unless
        (i) the Indemnifying Person and the Indemnified Person shall have
        mutually agreed to the contrary, (ii) the Indemnifying Person has failed
        within a reasonable time to retain counsel reasonably satisfactory to
        the Indemnified Person or (iii) the named parties in any such proceeding
        (including any impleaded parties) include both the Indemnifying Person
        and the Indemnified Person and representation of both parties by the
        same counsel would be inappropriate due to actual or potential differing
        interests between them. It is understood that the Indemnifying Person
        shall not, in connection with any proceeding or related proceeding in
        the same jurisdiction, be liable for the fees and expenses of more than
        one separate firm (in addition to any local counsel) for all Indemnified
        Persons, and that all such fees and expenses shall be reimbursed as they
        are incurred. Any such separate firm for the Underwriters and such
        control persons of Underwriters shall be designated in writing by
        Merrill Lynch and any such separate firm for the Trust, the Operating
        Partnership or the Company, the Trustees, directors, officers of the
        Company who sign the Registration Statement and such control persons of
        the Trust, the Operating Partnership or the Company shall be designated
        in writing by the Company. The Indemnifying Person shall not be liable
        for any settlement of any proceeding effected without its written
        consent, but if settled with such consent or if there be a final
        judgment for the plaintiff, the Indemnifying Person agrees to indemnify
        any Indemnified Person from and against any loss or liability by reason
        of such settlement or judgment. Notwithstanding the foregoing sentence,
        if at any time an Indemnified Person shall have requested an
        Indemnifying Person to reimburse the Indemnified Person for fees and
        expenses of counsel as contemplated by the second and third sentences of
        this paragraph, the Indemnifying Person agrees that it shall be liable
        for any settlement of any proceeding effected without its written
        consent if (i) such settlement is entered into more than 30 days after
        receipt by

                                       23

<PAGE>   27



        such Indemnifying Person of the aforesaid request and (ii) such
        Indemnifying Person shall not have reimbursed the Indemnified Person in
        accordance with such request prior to the date of such settlement. No
        Indemnifying Person shall, without the prior written consent of the
        Indemnified Person, effect any settlement of any pending or threatened
        proceeding in respect of which any Indemnified Person is or could have
        been a party and indemnity could have been sought hereunder by such
        Indemnified Person, unless such settlement includes an unconditional
        release of such Indemnified Person from all liability on claims that are
        the subject matter of such proceeding.

               (d) Indemnification for Reserved Securities. In connection with
        the offer and sale of the Reserved Securities, the Company agrees,
        promptly upon a request in writing, to indemnify and hold harmless the
        Underwriters from and against any and all losses, liabilities, claims,
        damages and expenses incurred by them as a result of the failure of
        eligible employees and persons having business relationships with the
        Company to pay for and accept delivery of Reserved Securities which, by
        the end of the first business day following the date of this Agreement,
        were subject to a properly confirmed agreement to purchase.

        SECTION 7. Contribution. If the indemnification provided for in Section
6 hereof is unavailable to an Indemnified Person or insufficient in respect of
any losses, claims, damages or liabilities referred to therein, then each
Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Trust, the Operating Partnership and the Company on the
one hand and the Underwriters on the other hand from the offering of the
Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Trust, the Operating Partnership and the Company on the one hand
and the Underwriters on the other hand in connection with the statements or
omissions as well as any other relevant equitable considerations. The relative
benefits received by the Trust, the Operating Partnership and the Company on the
one hand and the Underwriters on the other hand shall be deemed to be in the
same respective proportions as the proceeds from the offering of the Securities
after deducting the underwriting discount (before deducting expenses) received
by the Trust and the total underwriting discounts received by the Underwriters
bear to the aggregate initial public offering price of the Securities. The
relative fault of the Trust, the Operating Partnership and the Company on the
one hand and the Underwriters on the other hand shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Trust, the Operating Partnership or the
Company or by the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

        The Trust, the Operating Partnership, the Company and the Underwriters
agree that it would not be just and equitable if contribution pursuant to this
Section 7 were determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
that does not take account of the equitable considerations referred to in the
immediately preceding paragraph. The amount paid or payable by an Indemnified
Person as a result of the losses, claims, damages and

                                       24

<PAGE>   28



liabilities referred to in the immediately preceding paragraph shall be deemed
to include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such Indemnified Person in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 7, in no event shall an Underwriter be required to
contribute any amount in excess of the amount by which the total price at which
the Securities underwritten by it and distributed to the public were offered to
the public exceeds the amount of any damages that such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute pursuant to this
Section 7 are several in proportion to the respective number of the Securities
set forth opposite their names in Schedule A hereto, and not joint.

        The remedies provided for in this Section 7 are not exclusive and shall
not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

        The indemnity and contribution agreements herein and the representations
and warranties of the Trust, the Operating Partnership and the Company set forth
in this Agreement shall remain operative and in full force and effect regardless
of (i) any termination of this Agreement, (ii) any investigation made by or on
behalf of any Underwriter or any person controlling any Underwriter or by or on
behalf of the Trust, the Operating Partnership, the Company, its officers or
directors or any other person controlling the Company and (iii) acceptance of
and payment for any of the Securities.

        SECTION 8. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement or in certificates of officers of the Trust, the Operating Partnership
or the Company submitted pursuant hereto, shall remain operative and in full
force and effect, regardless of any investigation made by or on behalf of any
Underwriter or controlling person, or by or on behalf of the Trust, the
Operating Partnership or the Company, and shall survive delivery of the
Securities to the Underwriters.

        SECTION 9.    Termination of Agreement.

        (a) Termination; General. The Representatives may terminate this
Agreement, by notice to the Trust and the Operating Partnership, at any time at
or prior to Closing Time (i) if there has been, since the time of execution of
this Agreement or since the respective dates as of which information is given in
the Prospectus, any material adverse change in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the
REIT Entities considered as one enterprise, whether or not arising in the
ordinary course of business, or (ii) if there has occurred any material adverse
change in the financial markets in the United States, any outbreak of
hostilities or escalation thereof or other calamity or crisis or any change or
development involving a prospective change in national or international
political, financial or economic conditions, in each case the effect of which is
such as to make it, in the judgment of the Representatives, impracticable to
market the Securities or to enforce contracts for the sale of the Securities, or
(iii) if trading in any securities of the Operating Partnership or the Company
have been suspended or materially limited by the Commission or the New York
Stock Exchange, or if trading

                                       25

<PAGE>   29



generally on the American Stock Exchange or the New York Stock Exchange or in
the Nasdaq National Market has been suspended or materially limited, or minimum
or maximum prices for trading have been fixed, or maximum ranges for prices have
been required, by any of said exchanges or by such system or by order of the
Commission, the NASD or any other governmental authority, or (iv) if a banking
moratorium has been declared by either Federal, New York or California
authorities.

        (b) Liabilities. If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 6, 7 and 8 shall survive such termination and remain in full force and
effect.

        SECTION 10. Default by One or More of the Underwriters. If one or more
of the Underwriters shall fail at Closing Time or a Date of Delivery to purchase
the Securities which it or they are obligated to purchase under this Agreement
(the "Defaulted Securities"), the Representatives shall have the right, within
24 hours thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the Defaulted Securities in such amounts as may be agreed upon and upon the
terms herein set forth; if, however, the Representatives shall not have
completed such arrangements within such 24-hour period, then:

               (a) if the number of Defaulted Securities does not exceed 10% of
        the number of Securities to be purchased on such date, each of the
        non-defaulting Underwriters shall be obligated, severally and not
        jointly, to purchase the full amount thereof in the proportions that
        their respective underwriting obligations hereunder bear to the
        underwriting obligations of all non-defaulting Underwriters, or

               (b) if the number of Defaulted Securities exceeds 10% of the
        number of Securities to be purchased on such date, this Agreement or,
        with respect to any Date of Delivery which occurs after the Closing
        Time, the obligation of the Underwriters to purchase and of the Trust to
        sell the Option Securities to be purchased and sold on such Date of
        Delivery shall terminate without liability on the part of any
        non-defaulting Underwriter.

        No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

        In the event of any such default which does not result in a termination
of this Agreement or, in the case of a Date of Delivery which is after the
Closing Time, which does not result in a termination of the obligation of the
Underwriters to purchase and the Trust to sell the relevant Option Securities,
as the case may be, either the Representatives or the Trust shall have the right
to postpone Closing Time or the relevant Date of Delivery, as the case may be,
for a period not exceeding seven days in order to effect any required changes in
the Registration Statement or Prospectus or in any other documents or
arrangements. As used herein, the term "Underwriter" includes any person
substituted for an Underwriter under this Section 10.

in this Agreement is intended or shall be construed to give any person, firm or
corporation, other than the Underwriters, the Trust, the Operating Partnership
and the Company and their respective successors and the controlling persons and
officers and directors referred to in Sections 6 and 7 and their heirs and legal
representatives, any legal or equitable right, remedy or claim under or in

exclusive benefit of the Underwriters, the Trust, the Operating Partnership and
the Company and their respective successors, and said controlling persons and
officers and directors and their heirs and legal representatives, and for the
benefit of no other person, firm or corporation. No purchaser of Securities from
any Underwriter shall be deemed to be a successor by reason merely of such
purchase.

        SECTION 13.  GOVERNING LAW AND TIME.  THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK.  SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

               FORM OF OPINION OF TRUST'S, OPERATING PARTNERSHIP'S
                     AND THE COMPANY'S SPECIAL COUNSEL TO BE

        (vi) The Securities have been duly authorized for issuance and sale to
the Underwriters pursuant to the Purchase Agreement and, when issued and

consideration set forth in the Purchase Agreement, will be validly issued and

to personal liability by reason of being such a holder; the Securities conform
in all material respects to the description thereof contained in the Prospectus;
and the relative rights, preferences, interests and powers of the Securities are
as set forth in the Declaration relating thereto, and all such provisions are
valid under the Delaware Business Trust Act.

        (vii) The Common Securities have been duly authorized for issuance and
sale to the Company and certain members of management of the Company and, when

management of the Company against payment of the consideration thereof as set

issuance and sale to the Trust and, when issued and delivered by the Operating
Partnership pursuant to the OP Partnership

                                       A-1

<PAGE>   36



Agreement against payment of the consideration as described in the Prospectus,

Operating Partnership, is or will be liable to third parties for the obligations
of the Operating Partnership; the Series A Preferred L.P. Units conform in all
material respects to the description thereof contained in the Prospectus; and
the relative rights, preferences, interests and powers of the Series A Preferred

and all such provisions are valid under the Revised Uniform Limited Partnership
Act of the State of Delaware.

        (ix) The issuance of the Securities is not subject to any preemptive or
other similar rights of any securityholder of the Trust.

        (x) Assuming due authorization, execution and delivery of this Agreement
by the Company in its capacity as general partner of the Partnership, the
Purchase Agreement has been duly authorized, executed and delivered by the
Operating Partnership.

        (xi) The Purchase Agreement has been duly authorized, executed and
delivered by each of the Company and the Trust.

        (xii) Each of the Operating Partnership and the Property Partnership is
currently organized in conformity with the requirements for qualification as a
partnership under the Code and has been so organized since its formation, and
its method of operation has satisfied the requirements for taxation as a
partnership under the Code, and its proposed method of operation will enable it
to continue to do so and neither of the Operating Partnership nor the Property
Partnership has been or is taxable as a corporation.

        (xiii) The Trust is currently organized in conformity with the
requirements for qualification as a real estate investment trust under the Code
and has been so organized since its formation, and its method of operation has
satisfied the requirements for taxation as a real estate investment trust under
the Code, and its proposed method of operation will enable it to continue to do
so.

        (xiv) The Registration Statement, including any Rule 462(b) Registration
Statement, has been declared effective under the 1933 Act; any required filing
of the Prospectus pursuant to Rule 424(b) has been made in the manner and within
the time period required by Rule 424(b); and, to the best of our knowledge, no
stop order suspending the effectiveness of the Registration Statement or any
Rule 462(b) Registration Statement has been issued under the 1933 Act and no
proceedings for that purpose have been instituted or are pending or threatened
by the Commission.

        (xv) The Registration Statement, including any Rule 462(b) Registration
Statement, the Rule 430A Information and the Rule 434 Information, as
applicable, the Prospectus and each amendment or supplement to the Registration
Statement and Prospectus as of their respective effective or issue dates (other
than the financial statements and supporting schedules included therein or
omitted therefrom, as to which such counsel need express no opinion) complied as
to form in all material respects with the requirements of the 1933 Act and the
1933 Act Regulations.


                                       A-2

<PAGE>   37



        (xvi) If Rule 434 has been relied upon, the Prospectus was not
"materially different," as such term is used in Rule 434, from the prospectus
included in the Registration Statement at the time it became effective.

        (xvii) The form of certificate used to evidence the Securities complies
in all material respects with all applicable statutory requirements, with any
applicable requirements of the Declaration of the Trust and the requirements of
the New York Stock Exchange.

        (xviii)Such counsel does not know of any legal or governmental
proceedings pending or threatened to which any of the REIT Entities or any of
the Properties is subject that are required to be described in the Registration
Statement or the Prospectus and are not so described or of any statutes,
regulations, contracts or other documents that are required to be described in
the Registration Statement or the Prospectus or to be filed as exhibits to the
Registration Statement that are not described or filed as required.

        (xix) The information in the Prospectus under "Description of the Series
A Preferred Securities", "Description of the Series A Preferred L.P. Units",
"Relationship between the Preferred Securities and the Preferred L.P. Units,"
"Operating Partnership Agreement," "Business and Properties of the Operating
Partnership -- Legal Proceedings," "Certain Federal Income Tax Considerations"
and in the Registration Statement under Item 14, to the extent that it
constitutes matters of law, summaries of legal matters, the Declaration, the OP
Partnership Agreement or legal proceedings, or legal conclusions, has been
reviewed by us and is correct in all material respects.

        (xx) To the best of our knowledge, there are no persons with
registration rights or other similar rights to have any securities registered
pursuant to the Registration Statement or otherwise registered by the Trust or
the Operating Partnership under the 1933 Act.

        (xxi) Neither the Trust nor the Operating Partnership is an "investment
company" or an entity "controlled" by an "investment company," as such terms are
defined in the 1940 Act.

        (xxii) The Declaration has been duly authorized, executed and delivered
by the Company, the Operating Partnership and the Regular Trustee. Assuming due
authorization, execution and delivery of the Declaration by the Delaware Trustee
and the Property Trustee, the Declaration is a valid and legally binding
agreement of the Company and the Operating Partnership and enforceable against
the Company and the Operating Partnership in accordance with its terms, except
as enforceability thereof may be limited by bankruptcy, insolvency, or similar
laws affecting creditors' rights generally and by the availability of equitable
principles of general applicability. The execution, delivery and performance of
the Declaration and the consummation of the transactions set forth therein and
compliance by the Company and the Operating Partnership, to the extent a party
thereto, do not and will not contravene any provision of applicable law or the
certificate of limited partnership of the Operating Partnership, the OP
Partnership Agreement or any agreement or other instrument binding upon any of
the REIT Entities that is material to the REIT Entities, taken as a whole, or,
to the best knowledge of such counsel, any judgment or decree of any
governmental body, agency or court having jurisdiction over any of the REIT
Entities (it being

                                       A-3

<PAGE>   38



understood that such counsel expresses no opinion as to any judgment or decree
of the United States Department of Housing and Urban Development ("HUD")) and no
consent, approval, authorization or order of, or qualification with, any
governmental body or agency (it being understood that such counsel expresses no
opinion as to any consent, approval, authorization or order of, or qualification
with, HUD) is required for the execution and delivery by the Company and the
Operating Partnership of their respective obligations under the Declaration.

        (xxiii) Assuming due authorization, execution and delivery of each of
the Amended Agreements by the Company in its capacity as general partner of the
Operating Partnership, each of the Amended Agreements has been duly authorized,
executed and delivered by the Operating Partnership. Assuming due authorization,
execution and delivery of each of the Amended Agreements by the Company in its
individual capacity and its capacity as general partner of the Operating
Partnership, the execution and delivery of each of the Amended Agreements by the
Company and the Operating Partnership, to the extent a party thereto, do not and
will not contravene any provision of applicable law or the certificate of

        Nothing has come to our attention that would lead us to believe that the
Registration Statement or any amendment thereto, including the Rule 430A
Information and Rule 434 Information (if applicable), (except for financial
statements and schedules and other financial data included therein or omitted
therefrom, as to which we need make no statement), at the time such Registration
Statement or any such amendment became effective, contained an untrue statement
of a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading or that the
Prospectus or any amendment or supplement thereto (except for financial
statements and schedules and other financial data included therein or omitted
therefrom, as to which we need make no statement), at the time the Prospectus
was issued, at the time any such amended or supplemented prospectus was issued
or at the Closing Time, included or includes an untrue statement of a material
fact or omitted or omits to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

governed or qualified by, or that it is otherwise subject to, any treatise,

        At the time of the execution of this Agreement, the Capital
Contributions of the Partners are as set forth in Amendment No. 25 to Exhibit A

property by the merger of any other Person into the Partnership, Persons who
receive Partnership Interests in exchange for their interests in the Person
merging into the Partnership shall become Partners and shall be deemed to have
made Capital Contributions as provided in the applicable merger agreement and as
set forth in an amendment to Exhibit A. Each Partner shall own Partnership Units
in the amount set forth for such Partner in Exhibit A, as the same may be
amended from time to time, and shall have a Percentage Interest in the Junior
Partnership Interests or in a series of Preferred Limited Partnership Interests
as set forth for such Partner in Exhibit A, as the same may be amended from time
to time, which Percentage Interest shall be adjusted in Exhibit A from time to
time by the General Partner to the extent necessary to reflect accurately sales,

Units as provided in such TRC Contribution Agreement, then Exhibit A shall be
further amended (i) so that the "Gross Asset Value of Contributed Property" set
forth opposite the name of TRC in Exhibit A shall be increased by the amount of
such Contingent Contribution Value and (ii) the number of Common Limited Partner
Units owned by TRC and the Percentage Interests of the General Partner and all
the Common Limited Partners in the Junior Partnership Interests set forth in

Asset Value, the General Partner, The Irvine Company and TRC agree that the
amount set forth opposite the name of TRC under "Gross Asset Value of
Contributed Property" in Exhibit A, as the same may be increased as described
above, constitutes the fair market value of the assets contributed by TRC to the
Partnership. At the Contingent Contribution Value Payment Date (as defined in
such TRC Contribution Agreement), in the event that the Partnership is obligated
to issue TRC additional Common Limited Partner Units, then the General Partner
shall issue TRC a certificate representing such Common Limited Partner Units,
and Exhibit A shall be modified accordingly as provided above. The Partners
acknowledge and agree that this paragraph reflects the provisions of Sections 16
and 17 of Amendment No. 7 of the Prior Agreement.

contribute such Property to the Partnership. Upon such contribution the
Partnership will be deemed to have issued to the General Partner a number of
General Partner Units equal to the number of REIT Shares issued by the General
Partner in such acquisition divided by the Conversion Factor in effect on the
date of issuance of such REIT Shares, and the Junior Percentage Interest of the
General Partner and all other Common Limited Partners shall be adjusted based on
that number of Partnership Units.

Agreement for an additional Common Limited Partner Interest, the Partnership
will issue a number of Common Limited Partner Units equal to the amount of
Common Limited Partner Units determined pursuant to the Land Rights Agreement,

Partner and all other Common Limited Partners shall be adjusted based on that

non-recourse to the General Partner, except to the extent otherwise agreed to by
the General Partner.

        Section 4.5.  Additional Funding and Capital Contributions

        A. General. The General Partner may, at any time and from time to time
determine that the Partnership requires additional funds ("Additional Funds")
for the acquisition of additional Properties or for such other purposes as the
General Partner may determine. Additional Funds may be raised by the
Partnership, at the election of the General Partner, in any manner provided in,
and in accordance with, the terms of this Section 4.5. Except as set forth in
this Section 4.5, no Person shall have any preemptive, preferential,
participation or similar right or rights to subscribe for or acquire any
Partnership Interest. Capital Contributions received pursuant to Section 11.7.C
will not be subject to Section 4.5.A.

        B. Notice of Additional Capital Contributions. The General Partner shall
give written notice (the "Funding Notice") to the Original Limited Partners of
the need for Additional Funds and the anticipated source(s) thereof.

        C. General Partner Loans. Upon delivery of a Funding Notice to the
Original Limited Partners, the General Partner, subject to Section 4.5.G below,
may enter into a Funding Debt including, but not limited to, a Funding Debt that
is convertible into REIT Shares and lend the Additional Funds to the Partnership
(a "General Partner Loan"). If the General Partner enters into such a Funding
Debt, the General Partner Loan will consist of the net proceeds from such
Funding Debt and, to the extent permitted by law, will be on the same terms and
conditions, including interest rate and repayment schedule, and providing for
the reimbursement of costs and expenses, as shall be applicable with respect to
or incurred in connection with such Funding Debt. Otherwise, all General Partner
Loans made pursuant to this Section 4.5 shall be on terms and conditions no less
favorable to the Partnership than would be available to the Partnership from any
third party.

        D. Additional Limited Partners. Upon delivery of a Funding Notice to the
Original Limited Partners, the General Partner on behalf of the Partnership may
raise all or any portion of the Additional Funds by accepting additional Capital
Contributions (i) in the case of cash, subject to Section 4.5.G, from any
Partners or any third party or (ii) in the case of property other than cash,
from any Partner and/or third parties, and either (A) in the case of Partners,
increasing such Partner's Partnership Interest, or (b) in the case of a third
party, admitting such third party as an Additional Limited Partner. Subject to
the terms of this Section 4.5 and to the definition of



                                       29
<PAGE>   35


Gross Asset Value, the General Partner shall determine in good faith the amount,
terms and conditions of such additional Capital Contributions.

        E. Issuance of Shares or Securities by the General Partner. The General
Partner shall not issue any additional REIT Shares (other than REIT Shares
issued pursuant to Section 4.3.A, 4.6, 4.8 or 8.6 hereof or pursuant to a
dividend or distribution (including any stock split) of REIT Shares to all of
its stockholders), shares of preferred stock of the General Partner or New
Securities unless (i) the General Partner shall make a Capital Contribution of
the proceeds from the issuance of such additional REIT Shares, shares of
preferred stock or New Securities, as the case may be, and from the exercise of
the rights contained in such additional New Securities, as the case may be,
provided that with respect to any issuance of preferred stock of the General
Partner or New Securities, the General Partner at its option may, in lieu of
making a Capital Contribution and issuing Preferred Limited Partner Interests to
the General Partner as provided in Section 4.5.F hereof, loan the proceeds from
the issuance of such shares of preferred stock or New Securities to the
Partnership on a subordinated basis, such loan to be on terms and conditions no
less favorable to the Partnership than would be available to the Partnership
from a third party, and (ii) the General Partner shall have delivered to the
Original Limited Partners a Funding Notice regarding the securities to be
issued.

        F. Issuances of Additional Limited Partner Interests. In accordance with
this Section 4.5, the General Partner is hereby authorized, without the consent
of the Limited Partners, other than as provided in Section 7.3.D hereof or in a
Designation Instrument, to cause the Partnership from time to time to issue to
the Partners (including the General Partner) or other Persons Common Limited
Partner Interests (in addition to Common Limited Partner Interests issued in
accordance with Sections 4.3.B and 4.8.A hereof) and Preferred Limited Partner
Interests. Preferred Limited Partner Interests may be issued in one or more
series, with such designations, powers, preferences and relative, participating,
optional or other special rights, powers and privileges, including voting and
conversion rights and rights, powers and privileges senior to the General
Partner Interest and the Common Limited Partner Interests as shall be determined
by the General Partner in its sole and absolute discretion subject to the Act
and Delaware law and as set forth in a Designation Instrument, including,
without limitation, (i) the allocations of Tax Items to Preferred Limited
Partner Interests as a class or to a specific series of Preferred Limited
Partner Interests, (ii) the rights of a series of Preferred Limited Partner
Interests to share in Partnership distributions of Available Cash, and (iii) the
rights of a series of Preferred Limited Partner Interests upon dissolution,
liquidation, winding-up or termination of the Partnership, including, without
limitation, the Liquidation Preference Amount with respect to such series.
Notwithstanding the foregoing, no Preferred Limited Partner Interests shall be
issued to the General Partner unless (i) the Preferred Limited Partner Interests
are issued in connection with an issuance of preferred stock of the General
Partner which shares of preferred stock have designations, preferences and other
rights such that the economic interests attributable to such shares of preferred
stock are substantially similar to the designations, preferences and other
rights of the Preferred Limited Partner Interests issued to the General Partner
and (ii) the General Partner shall make a Capital Contribution to the
Partnership in accordance with Section 4.5.E in



                                       30
<PAGE>   36


an amount equal to the proceeds raised in connection with the issuance of such
shares of preferred stock of the General Partner. Unless otherwise specified in
the Designation Instrument, with respect to any series of Preferred Limited
Partner Interests issued to the General Partner or IAC Capital Trust in
consideration of the proceeds received by the General Partner or IAC Capital
Trust from a concurrent offering of preferred stock of the General Partner or
preferred securities of IAC Capital Trust, respectively, the General Partner or
IAC Capital Trust, as the case may be, shall be deemed to have made
(notwithstanding the actual amount of the contribution) a Capital Contribution
to the Partnership in the amount of the gross proceeds of such issuance of
preferred stock or preferred securities, as the case may be, and the Partnership
shall be deemed to have simultaneously reimbursed the General Partner or IAC
Capital Trust, as the case may be, pursuant to Section 7.4.D of this Agreement
for the amount of the underwriting discounts and commissions and other issuance
cost incurred by the General Partner or IAC Capital Trust, as the case may be,
in connection with such issuance of such preferred stock or preferred
securities. Upon issuance of a series of Preferred Limited Partner Interests,
the Designation Instrument applicable to such series shall constitute an
amendment to this Agreement and shall become a part hereof whether or not
actually attached to this Agreement.

        G. Participation Rights of Partners. The Funding Notice delivered by the
General Partner prior to its making or accepting (on behalf of the Partnership)
any additional cash Capital Contributions pursuant to Section 4.5.A, 4.5.D,
4.5.E or, if any Preferred Limited Partner Interests are convertible into, or
exercisable or exchangeable for, Common Limited Partner Interests or REIT Shares
or securities whether issued by the Partnership or the General Partner which are
convertible into, or exercisable or exchangeable for, REIT Shares, 4.5.F hereof
shall contain the total amount of additional Capital Contributions sought to be
made to the Partnership, and the terms and conditions pertaining thereto. Each
Original Limited Partner then holding a Common Limited Partner Interest may
elect to make an additional Capital Contribution not to exceed the product of
(i) the total amount of additional Capital Contributions being sought, and (ii)
such Partner's Junior Percentage Interest (with such product deemed the "Pro
Rata Contribution"). The Funding Notice delivered by the General Partner prior
to its making any loans to the Partnership pursuant to Section 4.5.C herein
shall contain the total amount of the loan to be made to the Partnership. Each
Original Limited Partner then holding a Common Limited Partner Interest may
elect to participate in such loan in an amount not to exceed the product of (i)
the total amount of the loan, and (ii) such Limited Partner's Junior Percentage
Interest (with such product deemed the "Pro Rata Participation"). Such election
shall be made, if at all, by providing written notice thereof (the "Election
Notice") to the General Partner within fifteen (15) days after delivery of the
Funding Notice. Failure to respond to such notice shall be deemed to be an
election by such Original Limited Partner not to make such Capital Contribution
or participate in such loan. Such Election Notice shall contain the amount of
the additional Capital Contribution or the loan participation, if any, the
Original Limited Partner is to make (such additional Capital Contribution not to
exceed the respective Pro Rata Contribution of such Original Limited Partner and
such loan participation not to exceed the respective Pro Rata Participation of
such Original Limited Partner) equal to all or any portion of its Pro Rata
Contribution or Pro Rata Participation.

        H.     Percentage Interest Adjustments.

        (1) Upon the acceptance of additional cash Capital Contributions
pursuant to this Section 4.5, the Percentage Interests of the Partners shall be
adjusted based upon the number of Partnership Units issued in connection with
such Capital Contribution, provided that in connection with a Capital
Contribution by any Original Limited Partner pursuant to an Election Notice
under Section 4.5.G in response to (i) a Funding Notice relating to the Second
Offering, such Original Limited Partner shall be deemed to have contributed to
the Partnership an amount equal to the cash actually contributed by such
Original Limited Partner on the Adjustment Date, minus an amount equal to the
aggregate underwriting discounts and commissions that would have been applicable
to REIT Shares if the cash contributed by such Original Limited Partner on the
Adjustment Date had been used to acquire REIT Shares in the Second Offering, and
(ii) a Funding Notice relating to any offering of REIT Shares subsequent to the
Second Offering in which the amount of cash actually contributed by such
Original Limited Partner per Common Limited Partner Unit (the "L.P. Per Unit
Contribution") is greater than the amount of cash per General Partner Unit
actually contributed by the General Partner in respect of the REIT Shares sold
in such offering (the "G.P. Per Unit Contribution"), such Original Limited
Partner shall be deemed to have contributed to the Partnership an amount equal
to the cash actually contributed by such Original Limited Partner on the
Adjustment Date minus an amount equal to the product of (A) the L.P. Per Unit
Contribution minus the G.P. Per Unit Contribution and (B) the number of Common
Limited Partner Units purchased by such Original Limited Partner pursuant to
such Election Notice.

        (2) Upon the acceptance of additional Capital Contributions pursuant to
this Section 4.5 in the form of Property other than cash, the amount of the
Capital Contribution shall be equal to the Gross Asset Value of the Property
contributed as of the Adjustment Date, net of any liabilities assumed by the
Partnership in connection with such assets or Nonrecourse Liabilities to which
such Property is subject, and the Percentage Interests of the Partners shall be
adjusted based upon the number of Partnership Units issued in connection with
such Capital Contribution; provided that with respect to the Capital
Contribution made by TRC pursuant to the TRC Contribution Agreement, the Junior
Percentage Interest of TRC, the General Partner and all other Common Limited
Partners shall be adjusted based on the number of Common Limited Partnership
Units issued from time to time to TRC pursuant to such TRC Contribution
Agreement as provided in Section 4.1.

        (3) Upon the acceptance of additional Capital Contributions pursuant to
this Section 4.5 in the form of cash and other Property, the amount of the
Capital Contribution shall be equal to the sum of (A) the amount of cash
contributed on the Adjustment Date and (B) the Gross Asset Value of the Property
contributed as of the Adjustment Date, net of any liabilities assumed by the
Partnership in connection with such assets or Nonrecourse Liabilities to which
the Property is subject, and the Percentage Interests of the Partners shall be
adjusted based on the number of Partnership Units issued in connection with such
Capital Contribution.

        Section 4.6.  Stock Incentive Plans

        If at any time or from time to time, in connection with the General
Partner's Stock Incentive Plans, any stock options granted are duly exercised or
stock is issued in satisfaction of phantom stock unit grants, or stock becomes
non-forfeitable pursuant to a vesting provision:

                      A. The General Partner shall, as soon as practicable after
               such exercise, make a Capital Contribution to the Partnership in
               an amount equal to the exercise price paid to the General Partner
               by such exercising party in connection with the exercise of the
               stock option or the purchase price, if any, for such stock; and

                      B. Notwithstanding the amount of the Capital Contribution
               actually made pursuant to Section 4.6.A above, the General
               Partner shall be deemed to have contributed to the Partnership as
               a Capital Contribution, in consideration of an additional General
               Partner Interest, an amount equal to the Value as of the date of
               exercise (provided, that, for these purposes, only the trading
               date on which the purchase of the REIT Shares by such exercising
               party is consummated shall be considered) or the date of delivery
               or vesting of shares, as the case may be, multiplied by the
               number of REIT Shares acquired under the General Partner's Stock
               Incentive Plans.

                      C. A Junior Percentage Interest adjustment shall be made
               pursuant to the terms of Section 4.5.H in which the General
               Partner shall be treated as having made a cash contribution equal
               to the amount described in Section 4.6.B. hereof.

        Section 4.7.  No Third Party Beneficiary

        No creditor or other third party having dealings with the Partnership
shall have the right to enforce the right or obligation of any Partner to make
Capital Contributions or loans or to pursue any other right or remedy hereunder
or at law or in equity, it being understood and agreed that the provisions of
this Agreement shall be solely for the benefit of, and may be enforced solely
by, the parties hereto and their respective successors and assigns. None of the
rights or obligations of the Partners herein set forth to make Capital
Contributions or loans to the Partnership shall be deemed an asset of the
Partnership for any purpose by any creditor or other third party, nor may such
rights or obligations be sold, transferred or assigned by the Partnership or
pledged or encumbered by the Partnership to secure any debt or other obligation
of the Partnership or of any of the Partners.

        Section 4.8.  DRIP/ACP Plans



                                       33
<PAGE>   39


        A. If at any time or from time to time, in connection with the General
Partner's DRIP/ACP Plan, any REIT Shares are to be issued by the General Partner
out of its authorized but unissued REIT Shares in satisfaction of the General
Partner's obligations thereunder:

                      (1) Promptly following the close of business on the third
               business day preceding each DRIP/ACP Investment Date but subject
               to having received the notice referred to in clause (5) below,
               the General Partner shall give notice (which shall constitute a
               Funding Notice for purposes of Section 4.5.G.) to each Original
               Limited Partner then holding a Common Limited Partner Interest of
               the DRIP/ACP Investment Amount to be invested in newly issued
               REIT Shares on such DRIP/ACP Investment Date. Such notice shall
               also set forth the Maximum Limited Partner Investment Amount of
               the Original Limited Partners and the percentage of the DRIP/ACP
               Investment Amount constituting the DRIP Investment Amount (the
               "DRIP Percentage") and the percentage constituting the ACP
               Investment Amount.

                      (2) Not later than the close of business on the business
               day immediately preceding each DRIP/ACP Investment Date, the
               Original Limited Partners then holding Common Limited Partner
               Interests shall give irrevocable written notice to the General
               Partner of whether the Original Limited Partners or any one or
               more of them elect to make a cash investment on such DRIP/ACP
               Investment Date (not to exceed the Maximum Limited Partner
               Investment Amount) for the purchase of additional Common Limited
               Partner Interests in order to maintain the aggregate Junior
               Percentage Interest of the Original Limited Partners in the
               Partnership. Such notice shall specify the Actual Limited Partner
               Investment Amount if the amount to be invested is less than the
               Maximum Limited Partner Investment Amount and the identities of
               the Original Limited Partner or Partners which will make such
               cash investment, provided that the Original Limited Partners
               shall have the right to designate any wholly owned subsidiary of
               The Irvine Company as the entity which shall make a Capital
               Contribution in respect of all or a portion of the Actual Limited
               Partner Investment Amount (the Original Limited Partner or
               Partners or such subsidiary making the cash investment, the
               "Investing Entities"). Failure by the Original Limited Partners
               to respond to the Funding Notice shall be deemed an election by
               such Limited Partners not to make any cash investment on such
               DRIP/ACP Investment Date.

                      (3) The General Partner shall, as soon as practicable
               following the DRIP/ACP Investment Date, make a Capital
               Contribution to the Partnership in an amount equal to the
               DRIP/ACP Investment Amount for such DRIP/ACP Investment Date,
               provided that notwithstanding the amount of the Capital
               Contribution actually made pursuant to the foregoing, the General
               Partner shall be deemed to have contributed to the Partnership as
               a Capital Contribution, in consideration of an additional General
               Partner Interest, an amount equal to the



                                       34
<PAGE>   40


               Value as of the date of issuance of the REIT Shares issued by the
               General Partner on such DRIP/ACP Investment Date pursuant to the
               DRIP/ACP Plan (provided, that, for these purposes, only the
               DRIP/ACP Investment Date shall be considered) multiplied by the
               number of REIT Shares issued on such DRIP/ACP Investment Date
               pursuant to the DRIP/ACP Plan. Upon such contribution the
               Partnership will be deemed to have issued to the General Partner
               a number of General Partner Units equal to the number of newly
               issued REIT Shares issued by the General Partner on such DRIP/ACP
               Investment Date pursuant to the DRIP/ACP Plan, and the Junior
               Percentage Interest of the General Partner and all other Common
               Limited Partners shall be adjusted based on that number of
               Partnership Units.

                      (4) As soon as practicable following the DRIP/ACP
               Investment Date, the Investing Entities shall make a Capital
               Contribution to the Partnership in an amount equal to the Actual
               Limited Partner Investment Amount for such DRIP/ACP Investment
               Date. Upon such contribution the Partnership will issue a number
               of Common Limited Partners Units equal to the Corresponding L.P.
               Unit Amount, and the Junior Percentage Interest of the General
               Partner and the Common Limited Partners shall be adjusted based
               on that number of Partnership Units. Notwithstanding the amount
               of the Capital Contribution actually made pursuant to the
               foregoing, each Investing Entity shall be deemed to have
               contributed to the Partnership as a Capital Contribution an
               amount equal to the Value as of the date of issuance of the REIT
               Shares issued by the General Partner on such DRIP/ACP Investment
               Date pursuant to the DRIP/ACP Plan (provided, that for these
               purposes, only the DRIP/ACP Investment Date shall be considered)
               multiplied by the product of (i) the number of Common Limited
               Partner Units issued to such Investing Entity and (ii) the then
               current Conversion Factor.

                      (5) Promptly following the close of business on the third
               business day preceding each DRIP/ACP Investment Date, the
               Original Limited Partners shall give written notice to the
               General Partner of (i) the number of REIT Shares beneficially
               owned by the Original Limited Partners and Irvine Persons as of
               such close of business (whether under the DRIP/ACP Plan or
               otherwise), (ii) the aggregate amount of dividends to be paid
               with respect to such number of REIT Shares, if any, which such
               Persons have elected to be reinvested in newly issued REIT Shares
               on such DRIP/ACP Investment Date pursuant to the DRIP/ACP Plan
               and (iii) the aggregate amount of additional cash, if any, to be
               invested by all such Persons in newly issued REIT Shares on such
               DRIP/ACP Investment Date pursuant to the DRIP/ACP Plan. Such
               notice shall be provided by The Irvine Company on behalf of all
               such Persons so long as The Irvine Company or any of its
               Affiliates is the holder of a Common Limited Partner Interest
               (and thereafter by the Original Limited Partner holding the
               largest Junior Percentage Interest in the Partnership) and such
               information shall be used by the General Partner in determining
               the DRIP/ACP Investment Amount for purposes of the notice given



                                       35
<PAGE>   41

               by it pursuant to Section 4.8.A(1). In the event the notice
               required by this clause (5) is not given by the close of business
               on the second business day preceding a DRIP/ACP Investment Date,
               the General Partner shall determine the DRIP/ACP Investment
               Amount based on the following assumptions: (i) that the Original
               Limited Partners and Irvine Persons beneficially own the number
               of REIT Shares set forth in the most recent Form 3 or Form 4 or
               Schedule 13G filed by such Persons pursuant to the Securities
               Exchange Act of 1934, as amended, (ii) that such Persons will
               reinvest pursuant to the DRIP/ACP Plan all the dividends to be
               paid on such number of REIT Shares on the applicable DRIP/ACP
               Investment Date and (iii) that each such Person will make on the
               applicable DRIP/ACP Investment Date the maximum additional cash
               investment permitted by the DRIP/ACP Plan to be made by such
               Person on such DRIP/ACP Investment Date.

        B. If at any time or from time to time, in connection with the General
Partner's DRIP/ACP Plan, any REIT Shares are to be issued by the General Partner
out of its authorized but unissued REIT Shares in satisfaction of the General
Partner's obligations under Section 4.2 of the Miscellaneous Rights Agreement:

                      (1) The General Partner shall, as soon as practicable,
               after the issuance of such REIT Shares, make a Capital
               Contribution to the Partnership in an amount equal to the price
               paid to the General Partner for such REIT Shares as set forth in
               Section 4.2 of the Miscellaneous Rights Agreement.

                      (2) Notwithstanding the amount of the Capital Contribution
               actually made pursuant to Section 4.8.B(1) above, the General
               Partner shall be deemed to have contributed to the Partnership as
               a Capital Contribution, in consideration of an additional General
               Partner Interest, an amount equal to the Value as of the date of
               issuance of such REIT Shares (provided, that, for these purposes,
               only the trade date on which the purchase of the REIT Shares is
               consummated shall be considered) multiplied by the number of REIT
               Shares issued pursuant to Section 4.2 of the Miscellaneous Rights
               Agreement.

                      (3) The Partnership will be deemed to have issued to the
               General Partner a number of General Partner Units equal to the
               number of newly issued REIT Shares issued by the General Partner
               pursuant to Section 4.2 of the Miscellaneous Rights Agreement and
               the Junior Percentage Interest of the General Partner and all
               Common Limited Partners shall be adjusted based on that number of
               Partnership Units.

                                  DISTRIBUTIONS

        Section 5.1.  Requirements and Characterization of Distributions

        The General Partner shall cause the Partnership to distribute quarterly
all, or such portion as the General Partner may in its discretion determine,
including, but not limited to, as a consequence of such reserves as the General
Partner may deem appropriate, of Available Cash generated by the Partnership
during such quarter to the Partners who are Partners on the applicable
Partnership Record Date with respect to such quarter in the following order of
priority:

                      (i) First, to the Preferred Limited Partners in such
               amount as is required for the Partnership to pay all
               distributions with respect to the Preferred Limited Partner Units
               held by such Preferred Limited Partners due or payable in
               accordance with the Designation Instrument or Instruments for
               such Preferred Limited Partner Units through the last day of such
               quarter (or the last day of the quarterly period set forth in
               such Designation Instrument or Instruments); such distributions
               to be made to the Preferred Limited Partners in such order of
               priority and with such preferences as have been established with
               respect to such Preferred Limited Partner Units as set forth in
               the Designation Instrument or Instruments; and

                      (ii) Then, to the General Partner and the Common Limited
               Partners in accordance with their respective Junior Percentage
               Interests on such Partnership Record Date.

Subject to the prior rights of holders of Preferred Limited Partner Units with
respect to distributions of Available Cash, the General Partner in its sole
discretion may distribute to the General Partner and the Common Limited Partners
Available Cash (excluding amounts previously distributed to Preferred Limited
Partners as provided above) in accordance with their Junior Percentage Interests
on a more frequent basis and provide for an appropriate record date. The General
Partner shall take such reasonable efforts consistent with its qualification as
a REIT, to cause the Partnership to distribute sufficient amounts to enable the
General Partner to pay stockholder dividends that will (a) satisfy the
requirements for qualifying as a REIT under the Code and Regulations, and (b)
avoid any federal income or excise tax liability of the General Partner.

        Notwithstanding anything to the contrary contained herein, in no event
shall any Partner receive a distribution of Available Cash in respect of Junior
Partnership Interests with respect to any quarter or other period until such
time as the Partnership has distributed to the Preferred Limited Partners an
amount sufficient to pay all distributions payable with respect to the



                                       37
<PAGE>   43


Preferred Limited Partner Interests held by such Preferred Limited Partners in
accordance with the Designation Instrument or Instruments through the last day
of the most recently ended quarterly period set forth in each such Designation
Instrument.

        Section 5.2.  Distributions in Kind

        No right is given to any Partner to demand and receive property other
than cash. The General Partner may determine, in its sole discretion but subject
to the rights of Preferred Limited Partner Interests, to make a distribution in
kind to the General Partner and the Common Limited Partners of Partnership
assets, and such assets shall be distributed in such a fashion as to ensure that
the fair market value is distributed and allocated in accordance with Articles
5, 6 and 10 hereof.

        Section 5.3.  Distributions Upon Liquidation

        Proceeds from a Terminating Capital Transaction, and any other cash
received or reductions in reserves made after commencement of the liquidation of
the Partnership, shall be distributed to the Partners in accordance with Section
13.2.

        Section 5.4.  Restricted Distributions

        Notwithstanding any provision to the contrary contained herein, the
Partnership, and the General Partner on behalf of the Partnership, shall not
make a distribution to any Partner on account of its interest in the Partnership
if such distribution would violate Section 17-607 of the Act or other applicable
law.

                                    ARTICLE 6

                                   ALLOCATIONS

        Section 6.1.  Allocations in General

        Except as otherwise provided in this Article 6, and subject to Section
11.6.C, Net Income and Net Loss will be allocated to each of the Partners at the
end of each calendar month using the interim closing of the books method and
taking into account varying interests in accordance with the greater part of the
month convention consistent with Section 11.6.C.

        Section 6.2.  Additional Allocation Provisions

        A.  Special Allocations

        For each Partnership Year there shall be a special allocation to the
Original Limited Partners (other than SVC and any Person (including the Members
of SVC) to whom SVC




                                       38
<PAGE>   44

Transfers its Common Limited Partner Interests) which when added to amounts
allocated under Section 6.1 and 6.3.B will result in a total allocation to such
Original Limited Partners of (i) all remaining low-income housing tax credits of
the Existing Property Partnership, determined solely by reference to the
adjusted tax basis of the assets of the Existing Property Partnership at June
30, 1995, allocated to the Partnership with respect to the Existing Property
Partnership Interest and (ii) all Depreciation allocated to the Partnership with
respect to the Existing Property Partnership Interest determined solely by
reference to the adjusted tax basis of the assets of the Existing Property
Partnership at June 30, 1995; it being understood that any additional low-income
housing tax credits becoming available to the Existing Property Partnership, and
any additional Depreciation resulting from increases to the adjusted tax basis
of the assets of the Existing Property Partnership, in each case from and after
July 1, 1995, shall not be subject to the special allocation provided for in
this clause (3). Except as provided in this Section 6.2.A, Depreciation shall be
allocated in accordance with Section 6.1 and 6.3.B.

        B.  Regulatory Allocations

        Notwithstanding the foregoing provisions of this Article 6:

                      (1) Minimum Gain Chargeback. Except as otherwise provided
               in Regulations Section 1.704-2(f), if there is a net decrease in
               Partnership Minimum Gain during any Partnership Year, each
               Partner shall be specially allocated items of Partnership income
               and gain for such year (and, if necessary, subsequent years) in
               an amount equal to such Partner's share of the net decrease in
               Partnership Minimum Gain, as determined under Regulations Section
               1.704-2(g). Allocations pursuant to the previous sentence shall
               be made in proportion to the respective amounts required to be
               allocated to each Partner pursuant thereto. The items to be
               allocated shall be determined in accordance with Regulations
               Sections 1.704- 2(f)(6) and 1.704-2(j)(2). This Section 6.2.B(1)
               is intended to qualify as a "minimum gain chargeback" within the
               meaning of Regulation Section 1.704-2(f) and shall be interpreted
               consistently therewith.

                      (2) Partner Minimum Gain Chargeback. Except as otherwise
               provided in Regulations Section 1.704-2(i)(4) or in Section
               6.2.B(1) hereof, if there is a net decrease in Partner Minimum
               Gain attributable to a Partner Nonrecourse Debt during any
               Partnership Year, each Partner who has a share of the Partner
               Minimum Gain attributable to such Partner Nonrecourse Debt,
               determined in accordance with Regulations Section 1.704-2(i)(5),
               shall be specially allocated items of Partnership income and gain
               for such year (and, if necessary, subsequent years) in an amount
               equal to such Partner's share of the net decrease in Partner
               Minimum Gain attributable to such Partner Nonrecourse Debt,
               determined in accordance with Regulations Section 1.704-2(i)(4).
               Allocations pursuant to the previous sentence shall be made in
               proportion to the respective amounts required to be allocated to
               each Partner pursuant thereto. The items to be so allocated shall



                                       39
<PAGE>   45

               be determined in accordance with Regulations Section
               1.704-2(i)(4) and 1.704- 2(j)(2). This Section 6.2.B(2) is
               intended to qualify as a "chargeback of partner nonrecourse debt
               minimum gain" within the meaning of Regulation Section 1.704-2(i)
               and shall be interpreted consistently therewith.

                      (3) Nonrecourse Deductions and Partner Nonrecourse
               Deductions. Any Nonrecourse Deductions for any Partnership Year
               shall be specially allocated to the Partners in accordance with
               their Percentage Interests. Any Partner Nonrecourse Deductions
               for any Partnership Year shall be allocated to each Partner who
               bears the economic risk of loss with respect to the Partner
               Nonrecourse Debt to which such Partner Nonrecourse Deductions are
               attributable, in accordance with Regulations Section 1.704-2(i).

                      (4) Qualified Income Offset. If any Partner unexpectedly
               receives an adjustment, allocation or distribution described in
               Regulations Section 1.704- 1(b)(2)(ii)(d)(4), (5) or (6), items
               of Partnership income and gain shall be allocated, in accordance
               with Regulations Section 1.704-1(b)(2)(ii)(d), to the Partner in
               an amount and manner sufficient to eliminate, to the extent
               required by such Regulations, the Adjusted Capital Account
               Deficit of the Partner as quickly as possible, provided that an
               allocation pursuant to this Section 6.2.B(4) shall be made if and
               only to the extent that such Partner would have an Adjusted
               Capital Account Deficit after all other allocations provided in
               this Article 6 have been tentatively made as if this Section
               6.2.B(4) were not in the Agreement. It is intended that this
               Section 6.2.B(4) qualify and be construed as a "qualified income
               offset" within the meaning of Regulations Section
               1.704-1(b)(2)(ii)(d) and shall be interpreted consistently
               therewith.

                      (5) Gross Income Allocation. If any Partner has a deficit
               Capital Account at the end of any Partnership Year which is in
               excess of the sum of (1) the amount (if any) such Partner is
               obligated to restore to the Partnership, and (2) the amount such
               Partner is deemed to be obligated to restore pursuant to the
               penultimate sentences of Regulations Sections 1.704-2(g)(1) and
               1.704-2(i)(5), each such Partner shall be specially allocated
               items of Partnership income and gain in the amount of such excess
               as quickly as possible to eliminate such deficit, provided that
               an allocation pursuant to this Section 6.2.B(5) shall be made if
               and only to the extent that such Partner would have a deficit
               Capital Account in excess of such sum after all other allocations
               provided in this Article 6 have been tentatively made as if this
               Section 6.2.B(5) and Section 6.2.B(4) were not in the Agreement.

                      (6) Limitation on Allocation of Net Loss. To the extent
               any allocation of Net Loss would cause or increase an Adjusted
               Capital Account Deficit as to any Partner, such allocation of Net
               Loss shall be reallocated among the other Partners



                                       40
<PAGE>   46

               in accordance with their respective Partnership Interests,
               subject to the limitations of this Section 6.2.B(6).

                      (7) Section 754 Adjustment. To the extent an adjustment to
               the adjusted tax basis of any Partnership asset pursuant to Code
               Section 734(b) or Code Section 743(b) is required, pursuant to
               Regulations Section 1.704- 1(b)(2)(iv)(m)(2) or (4) to be taken
               into account in determining Capital Accounts as the result of a
               distribution to a Partner in complete liquidation of his interest
               in the Partnership, the amount of such adjustment to the Capital
               Accounts shall be treated as an item of gain (if the adjustment
               increases the basis of the asset) or loss (if the adjustment
               decreases such basis) and such gain or loss shall be specially
               allocated to the Partners in accordance with their Percentage
               Interests in the Partnership in the event that Regulations
               Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Partners to
               whom such distribution was made in the event that Regulations
               Section 1.704-1(b)(2)(iv)(m)(4) applies.

                      (8) Curative Allocation. The allocations set forth in
               Sections 6.2.B(1), (2), (3), (4), (5), (6) and (7) hereof (the
               "Regulatory Allocations") are intended to comply with certain
               regulatory requirements, including the requirements of
               Regulations Sections 1.704-1(b) and 1.704-2. Notwithstanding the
               provisions of Sections 6.1 and 6.2.A, the Regulatory Allocations
               shall be taken into account in allocating other items of income,
               gain, loss and deduction among the Partners so that, to the
               extent possible without violating the requirements giving rise to
               the Regulatory Allocations, the net amount of such allocations of
               other items and the Regulatory Allocations to each Partner shall
               be equal to the net amount that would have been allocated to each
               such Partner if the Regulatory Allocations had not occurred.

        C. Excess Nonrecourse Liability Allocation. For purposes of determining
a Partner's proportional share of the "excess nonrecourse liabilities" of the
Partnership within the meaning of Regulations Sections 1.752-3(a)(3), each
Partner's interest in Partnership profits shall be such Partner's Percentage
Interest.

        D. Priority Allocation With Respect to Preferred Limited Partner
Interests. Notwithstanding any other provision of this Agreement, for each
Partnership Year, Partnership gross income shall be specially allocated to the
Preferred Limited Partners in an amount equal to the distributions received by
the Preferred Limited Partners pursuant to Section 5.1(i) hereof for such
Partnership Year (other than any distributions that are treated as being in
satisfaction of the Liquidation Preference Amount for any Preferred Limited
Partner Interest).

        Section 6.3.  Tax Allocations

        A. In General. Except as otherwise provided in this Section 6.3, for
income tax purposes each Tax Item shall be allocated among the Partners in the
same manner as its correlative item of "book" income, gain, loss or deduction is
allocated pursuant to Sections 6.1 and 6.2 hereof.

        B. Allocations Respecting Section 704(c) Revaluations. Notwithstanding
Section 6.3.A above, Tax Items with respect to Property of the Partnership that
is contributed to the Partnership with a Gross Asset Value that differs from its
basis in the hands of the contributing Partner immediately preceding the date of
contribution shall be allocated for income tax purposes pursuant to Regulations
promulgated under Section 704(c) of the Code to the extent of such difference
and thereafter in accordance with Section 6.3.A. The General Partner shall make
allocations in accordance with the deferred sale method of accounting with
respect to gain on such property if the Regulations under Section 704(c) of the
Code are applicable to the Contributed Properties of the Partnership.

                      Partnership to make distributions to its Partners in such
                      amounts as will permit the General Partner (so long as the
                      General Partner qualifies as a REIT) to avoid the payment
                      of any federal income tax (including, for this purpose,
                      any excise tax pursuant to Section 4981 of the Code) and
                      to make distributions to its stockholders sufficient to
                      permit the General Partner to maintain REIT status),
                      provided that,

<PAGE>   48

                      except as provided in Section 10.4, the General Partner is

                      lien or encumbrance on the Partnership's assets) and the
                      incurring of any obligations it deems necessary for the
                      conduct of the activities of the Partnership;

               (2)    the making of tax, regulatory and other filings, or
                      rendering of periodic or other reports to governmental or
                      other agencies having jurisdiction over the business or

                      conversion, option, privilege, or subscription right or
                      any other right available in connection with any assets at
                      any time held by the Partnership) or the merger or other
                      combination of the Partnership with or into another entity

                      to the extent required by Section 7.3 hereof), provided
                      that, in the event of any sale, exchange, disposition or
                      other transfer of any Property of the Partnership, or the

                      into another entity, the Partnership shall no later than
                      the end of the calendar quarter in which such sale,
                      exchange, disposition, other transfer, merger or
                      combination becomes a taxable event to the General Partner
                      or any of the Common Limited Partners effect a
                      distribution of cash pro rata by Junior Percentage

                      promissory note of the Partnership, bearing interest (to
                      the extent permitted by law) at a rate per annum equal to
                      the dividend yield on the REIT Shares, based on the most
                      recent quarterly dividend and the Value as of the date of
                      issuance of such note, and due and payable as soon as
                      reasonably practicable but in no event later than 45 days
                      after the date of issuance), in addition to its then

                      Contributions by Partners pursuant to Article 4 hereof.

        B. Except as provided in Section 7.3 hereof, each of the Limited

perform the above-mentioned agreements and transactions on behalf of the
Partnership without any further act, approval or vote of the Partners,
notwithstanding any other provision of this Agreement, the Act or any applicable
law, rule or regulation. The execution, delivery or performance by the General
Partner or the Partnership of any agreement authorized or permitted under this
Agreement shall not constitute a breach by the General Partner of any duty that
the General Partner may owe the Partnership or the Limited Partners or any other
Persons under this Agreement or of any duty stated or implied by law or equity.

        C. At all times from and after the Prior Agreement Effective Date, the
General Partner may cause the Partnership to obtain and maintain (i) casualty,
liability and other insurance on the Properties of the Partnership and (ii)
liability insurance for the Indemnitees hereunder.

        D. At all times from and after the Prior Agreement Effective Date, the
General Partner may cause the Partnership to establish and maintain any and all
reserves, working capital accounts and other cash or cash equivalents in such
amounts as the General Partner, in its sole discretion, deems appropriate and
reasonable from time to time.

        E. In exercising its authority under this Agreement, the General Partner
may, but shall be under no obligation to, take into account the tax consequences
to any Partner of any action taken by it. Except as otherwise provided in the
Declaration of Trust, the General Partner and the Partnership shall not have
liability to a Limited Partner under any circumstances as a result of an income
tax liability incurred by such Limited Partner as a result of an action (or
inaction) by the General Partner pursuant to its authority under this Agreement
so long as the action or inaction is taken in good faith.

        Section 7.2.  Certificate of Limited Partnership

        To the extent that such action is determined by the General Partner to
be reasonable and necessary or appropriate, the General Partner shall file
amendments to and restatements of the Certificate and do all the things to
maintain the Partnership as a limited partnership (or a partnership in which the
limited partners have limited liability) under the laws of the State of Delaware
and each other state or the District of Columbia, in which the Partnership may
elect to do business or own property. Subject to the terms of Section 8.5.A(4)
hereof, the General Partner



                                       46
<PAGE>   52

shall not be required, before or after filing, to deliver or mail a copy of the
Certificate or any amendment thereto to any Limited Partner. The General Partner
shall use all reasonable efforts to cause to be filed such other certificates or
documents as may be reasonable and necessary or appropriate for the formation,
continuation, qualification and operation of a limited partnership (or a
partnership in which the limited partners have limited liability to the extent
provided by applicable law) in the State of Delaware, the State of California,
and any other state, or the District of Columbia, in which the Partnership may
elect to do business or own property.

        A.     The General Partner may not take any action in contravention of
this Agreement, including, without limitation:

        (5)    enter into any contract, mortgage, loan or other agreement that

               satisfying its obligations under Section 8.6 in full or (ii) the
               ability of a Common Limited Partner from exercising its rights
               under Section 8.6 in full; except in each case with the written

               General Partner, or admit into the Partnership any successor
               General Partners;

        (5)    take title to assets (other than temporarily in connection with

               conduct business other than through the Partnership, or for the
               General Partner or the Partnership to engage in any business
               other than the ownership, construction, development and operation
               of multifamily rental apartment communities.

         C.    Notwithstanding Section 7.3.B hereof, the General Partner shall
have the power, without the Consent of any Limited Partners, to amend this
Agreement (including a Designation Instrument) as may be required to facilitate
or implement any of the foregoing purposes:

        (1)    to add to the obligations of the General Partner or surrender any

               the General Partner for the benefit of the Limited Partners;

        (2)    to reflect the admission, substitution, or withdrawal of Partners

               provision in this Agreement not inconsistent with law or with
               other provisions, or make other changes with respect to matters

payments, and allocations to which it may be entitled), the General Partner
shall not receive payments from the Partnership or be compensated for its
services as general partner of the Partnership.



                                       50

        B. The General Partner shall be reimbursed on a monthly basis, or such
other basis as the General Partner may determine in its reasonable discretion,
for all of its expenses including, without limitation, (i) expenses relating to
the ownership of interests in and operation of, or for the benefit of, the
Partnership, (ii) compensation of its officers and employees including, without
limitation, payments under the General Partner's Stock Incentive Plans that
provides for stock units, or other phantom stock, pursuant to which employees of
the General Partner will receive payments based upon dividends on or the value
of REIT Shares, (iii) director fees and expenses and (iv) all costs and expenses
of being a public company, including costs of filings with the SEC, reports and
other distributions to its stockholders, provided that, the amount of any
reimbursement shall be reduced by any interest earned by the General Partner
with respect to bank accounts or other instruments or accounts held by it on
behalf of the Partnership as permitted pursuant to Section 7.5 hereof. Such
reimbursements shall be in addition to any reimbursement of the General Partner
as a result of indemnification pursuant to Section 7.7 hereof.

        C. Any Limited Partner that incurs an expense attributable to a property
tax or assessment imposed upon a geographic land area, including, but not
limited to, any variable rate assessment, that includes a Contributed Property
may submit a request for reimbursement to the General Partner that states the
total amount of the property tax or assessment imposed upon the area and an
apportionment, in accordance with the requirements of local law, of such
property tax or assessment to the Contributed Property located within the area.
The Limited Partner shall include with such request a copy of a receipt
evidencing payment of the property tax or assessment. The General Partner shall
reimburse the Limited Partner for such amount within five (5) days of receipt of
the request for reimbursement.

        D. To the extent not previously paid by the Partnership pursuant to the
Declaration of Trust, the General Partner shall be reimbursed on a monthly
basis, or such other basis as the General Partner may determine in its
reasonable discretion, for all amounts incurred by it and payable by the
Partnership pursuant to the Declaration of Trust.

        Section 7.5.  Outside Activities of the General Partner

                      The General Partner shall not directly or indirectly enter
into or conduct any business, other than in connection with the ownership,
acquisition and disposition of Partnership Interests as General Partner and the
management of the business of the Partnership, and such activities as are
incidental thereto. The General Partner shall not incur any debts other than
that for which it may be liable in its capacity as General Partner of the
Partnership. Nothing contained herein shall be deemed to prohibit the General
Partner from executing guarantees of Partnership debt for which it would
otherwise be liable in its capacity as General Partner. Subject to Section 7.3.B
hereof, the General Partner shall not own any assets or take title to assets
(other than temporarily in connection with an acquisition prior to contributing
such assets to the Partnership) other than its Partnership Interest as a General
Partner and other than such cash and cash equivalents, bank accounts or similar
instruments or accounts as it deems




                                       51
<PAGE>   57

reasonably necessary, taking into account Section 7.1.D hereof and the
requirements necessary to qualify as a REIT to carry out its responsibilities
contemplated under this Agreement and the Certificate of Incorporation.
Notwithstanding the foregoing, if the Consent of the Common Limited Partners is
obtained in accordance with 7.3.B and Article 14 hereof to permit the General
Partner to acquire assets in its own name and to own Property other than through
the Partnership, the General Partner and the Common Limited Partners agree to
negotiate in good faith to amend this Agreement, including, without limitation,
the definition of Conversion Factor, to reflect such activities and the direct
ownership of assets by the General Partner. The General Partner and any
Affiliates of the General Partner may acquire Limited Partner Interests and
shall be entitled to exercise all rights of a Limited Partner relating to such
Limited Partner Interests. Notwithstanding the foregoing, the General Partner
may purchase and own common securities of IAC Capital Trust pursuant to the
terms of the Declaration of Trust, act as sponsor of IAC Capital Trust and take
all actions permitted to be taken by it under the Declaration of Trust and such
additional activities as are incidental thereto.

        Section 7.6.  Contracts with Affiliates

        A. The Partnership may lend or contribute funds or other assets to its
Subsidiaries or other Persons in which it has an equity investment, and such
Persons may borrow funds from the Partnership, on terms and conditions
established in the sole discretion of the General Partner. The foregoing
authority shall not create any right or benefit in favor of any Subsidiary or
any other Person.

        B. Except as provided in Section 7.5 hereof and subject to Section 3.1
hereof, the Partnership may transfer assets to joint ventures, other
partnerships, corporations or other business entities in which it is or thereby
becomes a participant upon such terms and subject to such conditions consistent
with this Agreement and applicable law as the General Partner, in its sole
discretion, believes are advisable.

        C. Except as expressly permitted by this Agreement, neither the General
Partner nor any of its Affiliates shall sell, transfer or convey any property to
the Partnership, directly or indirectly, except pursuant to transactions that
are determined by the General Partner in good faith to be fair and reasonable.

        D. The General Partner is expressly authorized to enter into, in the
name and on behalf of the Partnership, a right of first opportunity arrangement
and other conflict avoidance agreements with various Affiliates of the
Partnership and the General Partner, on such terms as the General Partner, in
its sole discretion, believes are advisable.

        E. The General Partner on its own behalf and on behalf of the
Partnership may enter into and perform its and the Partnership's obligations
under the Declaration of Trust.

        Section 7.7.  Indemnification



                                       52
<PAGE>   58

        A. To the fullest extent permitted by applicable law, the Partnership
shall indemnify each Indemnitee from and against any and all losses, claims,
damages, liabilities, joint or several, expenses (including, without limitation,
attorney's fees and other legal fees and expenses), judgments, fines,
settlements, and other amounts arising from any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or investigative,
that relate to the operations of the Partnership ("Actions") as set forth in
this Agreement in which such Indemnitee may be involved, or is threatened to be
involved, as a party or otherwise, provided that the Partnership shall not
indemnify an Indemnitee (i) for willful misconduct or a knowing violation of the
law, or (ii) for any transaction for which such Indemnitee received an improper
personal benefit in violation or breach of any provision of this Agreement.
Without limitation, the foregoing indemnity shall extend to any liability of any
Indemnitee, pursuant to a loan guaranty or otherwise, for any indebtedness of
the Partnership or any Subsidiary of the Partnership (including, without
limitation, any indebtedness which the Partnership or any Subsidiary of the
Partnership has assumed or taken subject to), and the General Partner is hereby
authorized and empowered, on behalf of the Partnership, to enter into one or
more indemnity agreements consistent with the provisions of this Section 7.7 in
favor of any Indemnitee having or potentially having liability for any such
indebtedness. It is the intention of this Section 7.7.A that the Partnership
indemnify each Indemnitee to the fullest extent permitted by law. The
termination of any proceeding by judgment, order or settlement does not create a
presumption that the Indemnitee did not meet the requisite standard of conduct
set forth in this Section 7.7.A. The termination of any proceeding by conviction
of an Indemnitee or upon a plea of nolo contendere or its equivalent by an
Indemnitee, or an entry of an order of probation against an Indemnitee prior to
judgment, does not create a presumption that such Indemnitee acted in a manner
contrary to that specified in this Section 7.7.A with respect to the subject
matter of such proceeding. Any indemnification pursuant to this Section 7.7
shall be made only out of the assets of the Partnership, and neither the General
Partner nor any Limited Partner shall have any obligation to contribute to the
capital of the Partnership or otherwise provide funds to enable the Partnership
to fund its obligations under this Section 7.7.

        B. To the fullest extent permitted by law, expenses incurred by an
Indemnitee who is a party to a proceeding or otherwise subject to or the focus
of or is involved in any Action shall be paid or reimbursed by the Partnership
as incurred by the Indemnitee in advance of the final disposition of the Action
upon receipt by the Partnership of (i) a written affirmation by the Indemnitee
of the Indemnitee's good faith belief that the standard of conduct necessary for
indemnification by the Partnership as authorized in this Section 7.7.A has been
met, and (ii) a written undertaking by or on behalf of the Indemnitee to repay
the amount if it shall ultimately be determined that the standard of conduct has
not been met.

        C. The indemnification provided by this Section 7.7 shall be in addition
to any other rights to which an Indemnitee or any other Person may be entitled
under any agreement, pursuant to any vote of the Partners, as a matter of law or
otherwise, and shall continue as to an Indemnitee who has ceased to serve in
such capacity and shall inure to the benefit of the heirs, successors, assigns
and administrators of the Indemnitee unless otherwise provided in a written



                                       53
<PAGE>   59

agreement with such Indemnitee or in the writing pursuant to which such
Indemnitee is indemnified.

        D. The Partnership may, but shall not be obligated to, purchase and
maintain insurance, on behalf of any of the Indemnitees and such other Persons
as the General Partner shall determine, against any liability that may be
asserted against or expenses that may be incurred by such Person in connection
with the Partnership's activities, regardless of whether the Partnership would
have the power to indemnify such Person against such liability under the
provisions of this Agreement.

        E. Any liabilities which an Indemnitee incurs as a result of acting on
behalf of the Partnership or the General Partner (whether as a fiduciary or
otherwise) in connection with the operation, administration or maintenance of an
employee benefit plan or any related trust or funding mechanism (whether such
liabilities are in the form of excise taxes assessed by the Internal Revenue
Service, penalties assessed by the Department of Labor, restitutions to such a
plan or trust or other funding mechanism or to a participant or beneficiary of
such plan, trust or other funding mechanism, or otherwise) shall be treated as
liabilities or judgments or fines under this Section 7.7, unless such
liabilities arise as a result of (i) such Indemnitee's intentional misconduct or
knowing violation of the law, or (ii) any transaction in which such Indemnitee
received a personal benefit in violation or breach of any provision of this
Agreement or applicable law.

        F. In no event may an Indemnitee subject any of the Partners to personal
liability by reason of the indemnification provisions set forth in this
Agreement.

        G. An Indemnitee shall not be denied indemnification in whole or in part
under this Section 7.7 because the Indemnitee had an interest in the transaction
with respect to which the indemnification applies if the transaction was
otherwise permitted by the terms of this Agreement.

        H. The provisions of this Section 7.7 are for the benefit of the
Indemnitees, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons. Any
amendment, modification or repeal of this Section 7.7 or any provision hereof
shall be prospective only and shall not in any way affect the limitations on the
Partnership's liability to any Indemnitee under this Section 7.7 as in effect
immediately prior to such amendment, modification or repeal with respect to
claims arising from or relating to matters occurring, in whole or in part, prior
to such amendment, modification or repeal, regardless of when such claims may
arise or be asserted.

        Section 7.8.  Liability of the General Partner

        A. Notwithstanding anything to the contrary set forth in this Agreement,
neither the General Partner nor any of its officers or directors shall be liable
for monetary damages to the




                                       54
<PAGE>   60

Partnership, any Partners or any Assignees for losses sustained or liabilities
incurred as a result of errors in judgment or of any act or omission if the
General Partner or such officer or director acted in such cases in good faith.

        B. Subject to its obligations and duties as General Partner set forth in
Section 7.1.A hereof, the General Partner may exercise any of the powers granted
to it by this Agreement and perform any of the duties imposed upon it hereunder
either directly or by or through its employees or agents (subject to the
supervision and control of the General Partner). The General Partner shall not
be responsible for any misconduct or negligence on the part of any such agent
appointed by it in good faith.

        C. Any amendment, modification or repeal of this Section 7.8 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the General Partner's, and its officers' and directors',
liability to the Partnership and the Limited Partners under this Section 7.8 as
in effect immediately prior to such amendment, modification or repeal with
respect to claims arising from or relating to matters occurring, in whole or in
part, prior to such amendment, modification or repeal, regardless of when such
claims may arise or be asserted.

        D. Notwithstanding anything herein to the contrary, except for fraud,
willful misconduct or gross negligence, or pursuant to any express indemnities
given to the Partnership by any Partner pursuant to any other written
instrument, no Partner shall have any personal liability whatsoever, to the
Partnership or to the other Partner, for the debts or liabilities of the
Partnership or the Partnership's obligations hereunder, and the full recourse of
the other Partner shall be limited to the interest of that Partner in the
Partnership. Without limitation of the foregoing, and except for fraud, willful
misconduct or gross negligence, or pursuant to any such express indemnity, no
property or assets of any Partner, other than its interest in the Partnership,
shall be subject to levy, execution or other enforcement procedures for the
satisfaction of any judgment (or other judicial process) in favor of any other
Partner(s) and arising out of, or in connection with, this Agreement. This
Agreement is executed by the officers of the General Partner solely as officers
of the same and not in their own individual capacities.

        E. To the extent that, at law or in equity, a Limited Partner has duties
(including fiduciary duties) and liabilities relating thereto to the Partnership
or the Partners, the Limited Partner shall not be liable to the Partnership or
to any other Partner for its good faith reliance on the provisions of this
Agreement. The provisions of this Agreement, to the extent that they restrict
the duties and liabilities of a Limited Partner otherwise existing at law or in
equity, are agreed by the Partners to replace such other duties and liabilities
of such Limited Partner.

        F. Whenever in this Agreement a Limited Partner is permitted or required
to make a decision (i) in its "sole discretion" or "discretion" or under a grant
of similar authority or latitude, the Limited Partner shall be entitled to
consider only such interests and factors as it desires, including its own
interests, and shall have no duty or obligation to give any consideration to any
interest of or factors affecting the Partnership or the other Partners or (ii)
in its "good faith" or



                                       55
<PAGE>   61

under another express standard, the Limited Partner shall act under such express
standard and shall not be subject to any other or different standards imposed by
this Agreement or any other agreement contemplated herein or by relevant
provisions of law or in equity or otherwise.

        G. Whenever in this Agreement the General Partner is permitted or
required to make a decision (i) in its "sole discretion" or "discretion" or
under a grant of similar authority or latitude, the General Partner shall be
required to make such decision in good faith after taking into consideration the
interests of the Partners or (ii) in its "good faith" or under another express
standard, the General Partner shall act under such express standard and shall
not be subject to any other or different standards imposed by this Agreement or
any other agreement contemplated herein or by relevant provisions of law or in
equity or otherwise.

        Section 7.9.  Other Matters Concerning the General Partner

        A. The General Partner may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, bond, debenture, or other
paper or document believed by it in good faith to be genuine and to have been
signed or presented by the proper party or parties.

        B. The General Partner may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers, architects, engineers,
environmental consultants and other consultants and advisers selected by it, and
any act taken or omitted to be taken in reliance upon the opinion of such
Persons as to matters which such General Partner reasonably believes to be
within such Person's professional or expert competence shall be conclusively
presumed to have been done or omitted in good faith and in accordance with such
opinion.

        C. The General Partner shall have the right, in respect of any of its
powers or obligations hereunder, to act through any duly appointed attorney or
attorneys-in-fact. Each such attorney shall, to the extent provided by the
General Partner in the power of attorney, have full power and authority to do
and perform all and every act and duty which is permitted or required to be done
by the General Partner hereunder.

        D. Notwithstanding any other provisions of this Agreement or the Act,
any action of the General Partner on behalf of the Partnership or any decision
of the General Partner to refrain from acting on behalf of the Partnership,
undertaken in the good faith belief that such action or omission is necessary or
advisable in order (i) to protect the ability of the General Partner to continue
to qualify as a REIT or (ii) to avoid the General Partner incurring any taxes
under Section 857 or Section 4981 of the Code, is expressly authorized under
this Agreement and is deemed approved by all of the Limited Partners.

        Section 7.10. Title to Partnership Assets



                                       56
<PAGE>   62


        Title to Partnership assets, whether real, personal or mixed and whether
tangible or intangible, shall be deemed to be owned by the Partnership as an
entity, and no Partner, individually or collectively, shall have any ownership
interest in such Partnership assets or any portion thereof. Title to any or all
of the Partnership assets may be held in the name of the Partnership or one or
more nominees, as the General Partner may determine. The General Partner hereby
declares and warrants that any Partnership assets for which legal title is held
in the name of the General Partner or any nominee or Affiliate of the General
Partner shall be held by the General Partner for the use and benefit of the
Partnership in accordance with the provisions of this Agreement; provided,
however, that the General Partner shall use its best efforts to cause beneficial
and record title to such assets to be vested in the Partnership as soon as
reasonably practicable. All Partnership assets shall be recorded as the property
of the Partnership in its books and records, irrespective of the name in which
legal title to such Partnership assets is held.

        Section 7.11. Reliance by Third Parties

        Notwithstanding anything to the contrary in this Agreement, any Person
dealing with the Partnership shall be entitled to assume that the General
Partner has full power and authority, without the consent or approval of any
other Partner or Person, to encumber, sell or otherwise use in any manner any
and all assets of the Partnership and to enter into any contracts on behalf of
the Partnership, and take any and all actions on behalf of the Partnership, and
such Person shall be entitled to deal with the General Partner as if the General
Partner were the Partnership's sole party in interest, both legally and
beneficially. Each Limited Partner hereby waives any and all defenses or other
remedies which may be available against such Person to contest, negate or
disaffirm any action of the General Partner in connection with any such dealing.
In no event shall any Person dealing with the General Partner or its
representatives be obligated to ascertain that the terms of this Agreement have
been complied with or to inquire into the necessity or expedience of any act or
action of the General Partner or its representatives. Each and every
certificate, document or other instrument executed on behalf of the Partnership
by the General Partner or its representatives shall be conclusive evidence in
favor of any and every Person relying thereon or claiming thereunder that (i) at
the time of the execution and delivery of such certificate, document or
instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Partnership and (iii)
such certificate, document or instrument was duly executed and delivered in
accordance with the terms and provisions of this Agreement and is binding upon
the Partnership.

        Section 8.1.  Limitation of Liability

        The Limited Partners shall have no liability under this Agreement except
as expressly provided in this Agreement, including Section 10.4 hereof, or under
the Act.

        Section 8.2.  Management of Business

        No Limited Partner or Assignee (other than the General Partner, any of
its Affiliates or any officer, director, employee, partner, agent or trustee of
the General Partner, the Partnership or any of their Affiliates, in their
capacity as such) shall take part in the operation, management or control of the
Partnership's business, transact any business in the Partnership's name or have
the power to sign documents for or otherwise bind the Partnership. The
transaction of any such business by the General Partner, any of its Affiliates
or any officer, director, employee, partner, agent or trustee of the General
Partner, the Partnership or any of their Affiliates, in their capacity as such,
shall not affect, impair or eliminate the limitations on the liability of the
Limited Partners or Assignees under this Agreement.

        Section 8.3.  Outside Activities of Limited Partners

        Subject to any agreements entered into pursuant to Section 7.6.D hereof
and any other agreements entered into by a Limited Partner or its Affiliates
with the General Partner, the Partnership or a Subsidiary, any Limited Partner
and any officer, director, employee, agent, trustee, Affiliate or shareholder of
any Limited Partner shall be entitled to and may have business interests and
engage in business activities in addition to those relating to the Partnership,
including business interests and activities that are in direct competition with
the Partnership or that are enhanced by the activities of the Partnership.
Neither the Partnership nor any Partners shall have any rights by virtue of this
Agreement in any business ventures of any Limited Partner or Assignee. Subject
to such agreements, none of the Limited Partners nor any other Person shall have
any rights by virtue of this Agreement or the partnership relationship
established hereby in any business ventures of any other Person (other than the
General Partner to the extent expressly provided herein) and such Person shall
have no obligation pursuant to this Agreement, subject to Section 7.6.D hereof
and any other agreements entered into by a Limited Partner or its Affiliates
with the General Partner, the Partnership or a Subsidiary, to offer any interest
in any such business ventures to the Partnership, any Limited Partner or any
such other Person, even if such opportunity is of a character which, if
presented to the Partnership, any Limited Partner or such other Person, could be
taken by such Person.

        Section 8.4.  Return of Capital



                                       58
<PAGE>   64

        Except as provided in a Designation Instrument, no Limited Partner shall
be entitled to the withdrawal or return of its Capital Contribution, except to
the extent of distributions made pursuant to this Agreement or upon termination
of the Partnership as provided herein. Except to the extent provided in Article
6 hereof or otherwise expressly provided in this Agreement (including pursuant
to a Designation Instrument), no Limited Partner or Assignee shall have priority
over any other Limited Partner or Assignee either as to the return of Capital
Contributions or as to profits, losses or distributions. Preferred Limited
Partner Units of a series shall be redeemed only in accordance with a
Designation Instrument relating thereto.

        Section 8.5.  Rights of Limited Partners Relating to the Partnership

        A. In addition to other rights provided by this Agreement or by the Act,
each Limited Partner shall have the right, for a purpose reasonably related to
such Limited Partner's interest as a Limited Partner in the Partnership, upon
written demand:

                      (1) to obtain a copy of the most recent annual and
               quarterly reports filed with the Securities and Exchange
               Commission by the General Partner pursuant to the Securities
               Exchange Act of 1934, as amended;

                      (2) to obtain a copy of the Partnership's federal, state
               and local income tax returns for each Partnership Year and the
               tax work papers prepared in connection with such returns;

                      (3) to obtain a current list of the name and last known
               business, residence or mailing address of each Partner; and

                      (4) to obtain a copy of this Agreement and the Certificate
               and all amendments thereto, together with executed copies of all
               powers of attorney pursuant to which this Agreement, the
               Certificate and all amendments thereto have been executed.

        B. The Partnership shall notify any Common Limited Partner, on request,
of the then current Conversion Factor or any change made to the Conversion
Factor.

        Section 8.6.  Exchange and Cash Tender Rights

        A. Each Original Limited Partner shall have the right (subject to the
terms and conditions set forth herein) to require the General Partner to acquire
all or a portion of the Common Limited Partner Units held by such Original
Limited Partner, including Common Limited Partner Units acquired by any Original
Limited Partner subsequent to the initial contribution, (such Common Limited
Partner Units being hereafter "Tendered Units") in exchange for, at the election
of such Original Limited Partner, (i) REIT Shares, in which event such required
acquisition shall be considered an "Exchange," or (ii) cash, in which event such
required acquisition shall be




                                       59
<PAGE>   65

considered a "Cash Tender." Any Exchange or Cash Tender shall be exercised
pursuant to a Notice of Exchange or Notice of Cash Tender, as the case may be,
delivered to the General Partner by the Original Limited Partner who is
exercising the relevant right (the "Tendering Partner").

        B. A Tendering Partner who wishes to effect an Exchange shall receive,
on the Specified Exchange Date, the REIT Shares Amount with respect to the
Tendered Units, subject to the Ownership Limit set forth in ARTICLE SIXTH of the
Certificate of Incorporation and to Section 8.6.G(2) hereof, provided such
Tendering Partner submits such information, certification and affidavits as the
General Partner requires pursuant to Section 8.6.I hereof in connection with the
application of the Ownership Limit. The REIT Shares Amount receivable after
giving effect to the provisions of Section 8.6.F shall be delivered as duly
authorized, validly issued, fully paid and nonassessable REIT Shares and, if
applicable, rights (as defined in the definition of REIT Shares Amount), free of
any pledge, lien, encumbrance or restriction, other than those provided in the
Certificate of Incorporation, the Bylaws of the General Partner, the Securities
Act and relevant state securities or blue sky laws. Notwithstanding any delay in
such delivery, the Tendering Partner shall be deemed the owner of such REIT
Shares and rights for all purposes, including without limitation, rights to
vote, consent, receive dividends, and to exercise rights, as of the Specified
Exchange Date.

        C. (1) A Tendering Partner effecting a Cash Tender shall have the right
to receive in cash on the Specified Cash Tender Date the Cash Tender Amount,
subject to Section 8.6.G(3) hereof. The General Partner shall purchase the
Tendered Units solely with the proceeds of a registered public offering (a
"Public Offering Funding") of a number of REIT Shares ("Registrable Shares")
equal to the REIT Shares Amount with respect to the Tendered Units.

           (2) Promptly upon receipt of a Notice of Cash Tender, the General
Partner shall give notice (a "Single Funding Notice") to all Original Limited
Partners then holding a Common Limited Partner Interest and require that all
such Original Limited Partners elect whether or not to effect a Cash Tender of
their Common Limited Partner Units to be funded through such Public Offering
Funding. In the event any such Original Limited Partner elects to effect such a
Cash Tender, it shall give notice thereof and of the number of Common Limited
Partner Units to be made subject thereto in writing to the General Partner
within 10 Business Days after receipt of the Single Funding Notice, and such
Original Limited Partner shall be treated as a Tendering Partner for all
purposes of this Section 8.6. In the event that an Original Limited Partner does
not so elect, it shall be deemed to have waived its right to effect a Cash
Tender for the current Twelve-Month Period, except that any such Original
Limited Partner holding more than 1,000,000 Common Limited Partner Units shall
continue to be permitted to effect a Cash Tender pursuant to this Section 8.6.C
during such Twelve-Month Period; provided that the General Partner shall not be
required to acquire Common Limited Partner Units pursuant to this Section 8.6.C
more than twice within a Twelve-Month Period.

        D. The General Partner shall purchase the Tendered Units on the
Specified Cash Tender Date for the Cash Tender Amount in immediately available
funds. Any proceeds from a Public Offering Funding that are in excess of the
Cash Amount shall be for the sole benefit of the General Partner. The General
Partner shall make a Capital Contribution of such amounts to the Partnership for
an additional General Partner Interest. Any such contribution shall not be
subject to the participation rights provided under Section 4.5.G but shall
entitle the General Partner to a Junior Percentage Interest adjustment pursuant
to Section 4.5.H hereof.

        E. The following additional terms and conditions shall apply to any
Public Offering Funding:

                             (1) The General Partner shall use its best efforts
               to effect as promptly as possible a registration, qualification
               or compliance (including, without limitation, the execution of an
               undertaking to file post-effective amendments, appropriate
               qualifications under applicable blue sky or other state
               securities laws and appropriate compliance with applicable
               regulations issued under the Securities Act and any other
               governmental requirements or regulations) as would permit or
               facilitate the sale and distribution of the REIT Shares;
               provided, the General Partner shall not by reason hereof, be
               required to submit to jurisdiction or taxation, or qualify to do
               business in any jurisdiction in which such submission or
               qualification would not be otherwise required; provided, further,
               if the General Partner shall deliver a certificate to the
               Tendering Partner stating that the General Partner has determined
               in the good faith judgment of its Board of Directors that such
               filing, registration or qualification would require disclosure of
               material non-public information, the disclosure of which would
               have a material adverse effect on the General Partner, then the
               General Partner may delay making any filing or delay the
               effectiveness of any registration or qualification for the
               shorter of (a) the period ending on the date upon which such
               information is disclosed to the public or ceases to be material
               or (b) an aggregate period of 90 days in connection with any
               Public Offering Funding.

                             (2) The General Partner shall advise the Tendering
               Partner, regularly and promptly upon any request, of the status
               of the registration, including the timing of all filings, the
               selection of and understandings with underwriters, dealers and
               brokers, the nature and contents of all communications with the
               Securities and Exchange Commission and other governmental bodies,
               the nature of marketing activities, and any other matters
               reasonably related to the timing, price and underwriting
               discounts and commissions relating to the Public Offering Funding
               and the compliance by the General Partner with its obligations
               with respect thereto. In addition, the General Partner and each
               Tendering Partner may, but shall be under no obligation to, enter
               into understandings in writing ("Pricing Agreements") whereby the
               Tendering Partner will agree in advance as to the minimum Public
               Offering Funding Amount per Registrable Share at or below




                                       61
<PAGE>   67

               the Cash Amount at which such Tendering Partner will agree in
               advance not to become a Withdrawing Partner under Section
               8.6.E(3) below. Furthermore, the General Partner shall establish
               pricing notification procedures with each Tendering Partner, such
               that the Tendering Partner will have the maximum opportunity
               practicable to determine whether to become a Withdrawing Partner
               pursuant to Section 8.6.E(3) below.

                             (3) Upon agreement between the General Partner and
               the managing underwriter(s) engaged by the General Partner in
               order to sell the Registrable Shares of the price per share at
               which the Registrable Shares are to be offered to the public and
               the underwriting discounts and commissions with respect thereto
               (the "Pricing Information"), the General Partner shall
               immediately use its best efforts to notify the Tendering Partner
               of the Pricing Information. Each Tendering Partner shall have one
               hour (or such additional time as may be extended by the General
               Partner in its sole discretion) to elect to withdraw his Cash
               Tender (a Tendering Partner making such an election being a
               "Withdrawing Partner"), and Common Limited Partner Units with a
               REIT Shares Amount equal to such excluded Registrable Shares
               shall be considered to be withdrawn from the related Cash Tender.
               If a Tendering Partner, within such period, does not notify the
               General Partner of such Tendering Partner's election not to
               become a Withdrawing Partner, then such Tendering Partner shall,
               except as otherwise provided in a Pricing Agreement, be deemed to
               have elected to become a Withdrawing Partner, without liability
               to the General Partner. To the extent that the General Partner is
               unable to notify any Tendering Partner, such unnotified Tendering
               Partner shall, except as otherwise provided in any Pricing
               Agreement, be deemed to have elected to become a Withdrawing
               Partner. Each Tendering Partner who does not become a Withdrawing
               Partner shall have the right, subject to the approval of the
               managing underwriter(s) in its sole discretion, to Cash Tender
               additional Common Limited Partner Units in a number no greater
               than the number of Common Limited Partner Units withdrawn. If
               more than one Tendering Partner so elects to tender additional
               Common Limited Partner Units, then such additional Common Limited
               Partner Units shall be tendered on a pro rata basis, based on the
               number of additional Common Limited Partner Units sought to be so
               Cash Tendered. In the event that Original Limited Partners
               withdraw in accordance with this paragraph such that the Public
               Offering Funding is canceled, then each Withdrawing Partner shall
               bear its pro rata share of the expenses, if any, reasonably
               incurred in connection with the unconsummated Public Offering
               Funding including, legal and accounting fees and expenses,
               Securities and Exchange Commission registration fees, state blue
               sky and securities law fees and expenses, printing expenses, NASD
               filing fees and listing fees (such share calculated as if such
               Partner had not been a Withdrawing Partner). If the Public
               Offering Funding is consummated, then the Withdrawing Partner
               will not be subject to such expenses.

                             (4) The General Partner shall take all reasonable
               action in order to effectuate the sale of the Registrable Shares
               including, but not limited to, the entering into of an
               underwriting agreement in customary form with the book- running
               managing underwriter selected for such underwriting by the
               Tendering Partner or, if there is more than one Tendering
               Partner, by the Tendering Partner who, together with the
               Affiliates of such Tendering Partner, beneficially owns the
               greatest number of Common Limited Partner Units then being made
               subject to a Cash Tender; provided that such managing underwriter
               shall be reasonably acceptable to the General Partner. The
               General Partner may select any additional investment banks and
               managers to be used in connection with the offering; provided
               that such additional investment bankers and managers must be
               reasonably satisfactory to the Tendering Partners who, together
               with the Affiliates of such Tendering Partner, beneficially own
               the majority of Common Limited Partner Units being Tendered.
               Notwithstanding any other provision of this Agreement, if the
               managing underwriter(s) advises the General Partner in writing
               that marketing factors require a limitation of the number of
               shares to be underwritten, then the General Partner shall so
               advise all Tendering Partners and the number of Common Limited
               Partner Units to be sold to the General Partner pursuant to the
               Cash Tender shall be allocated among all Tendering Partners in
               proportion, as nearly as practicable, to the respective number of
               Common Limited Partner Units as to which each Tendering Partner
               elected to effect a Cash Tender. No Registrable Shares excluded
               from the underwriting by reason of the managing underwriter's
               marketing limitation shall be included in such registration.

                             (5) If the managing underwriter has not limited the
               number of Registrable Shares to be underwritten, then the General
               Partner may include in any registration filed pursuant to Section
               8.6.D hereof securities (i) for its own account, subject to
               Section 4.5.H hereof, and (ii) for the account of others, in
               either case, only if and to the extent that (x) the managing
               underwriter, the General Partner and Tendering Partners owning
               Common Limited Partner Units representing at least seventy-five
               percent (75%) of the Common Limited Partner Units with respect to
               which the Public Offering Funding is being effected so agree in
               writing, and (y) the right of any party to Cash Tender Common
               Limited Partner Units pursuant to this Section 8.6, and the Cash
               Tender Amount to be received by such party (including by virtue
               of the number of Registrable Shares which would otherwise have
               been included in such registration and underwriting, the offering
               price for such Registrable Shares and the underwriting
               commissions or discounts for such Registrable Shares) will not
               thereby be limited, reduced or adversely affected. In the event
               that the managing underwriter determines that the size of the
               registration should be reduced, securities included by the
               General Partner shall be reduced or eliminated from the
               registration prior to reducing securities included by any other
               Person in the registration.



                                       63

        F. Notwithstanding the provisions of Section 8.6.A hereof, a Common
Limited Partner shall not be entitled to effect an Exchange to the extent that
the ownership or right to acquire REIT Shares by such Partner on the date of the
Notice of Exchange, or any date thereafter, through and including the Specified
Exchange Date, would be prohibited under the Certificate of Incorporation.

        G. Notwithstanding anything herein to the contrary, with respect to any
Exchange or Cash Tender pursuant to this Section 8.6:

                             (1) All Common Limited Partner Units acquired by
               the General Partner pursuant thereto shall automatically, and
               without further action required, be converted into and deemed to
               be General Partner Interests comprised of the same number of
               General Partner Units.

                             (2) Subject to the Ownership Limit, no Original
               Limited Partner may effect an Exchange (a) for less than 10,000
               Common Limited Partner Units or, if such Limited Partner holds
               less than 10,000 Common Limited Partner Units, all of the Common
               Limited Partner Units held by such Limited Partner; or (b) for
               more than one-third of the number of Common Limited Partner Units
               held by such Limited Partner; provided that, if the Original
               Limited Partners own collectively 6,149,000 Common Limited
               Partner Units or less, such Original Limited Partners may
               Exchange all their Common Limited Partner Units subject to the
               Ownership Limit;

                             (3) No Original Limited Partner may effect a Cash
               Tender (a) for less than 100,000 Common Limited Partner Units or,
               if such Limited Partner holds less than 100,000 Common Limited
               Partner Units, all of the Common Limited Partner Units held by
               such Partner, or (b) for more than one-third of the number of
               Common Limited Partner Units; provided that, if the Original
               Limited Partners own 6,149,000 Common Limited Partner Units or
               less, such Original Limited Partners may effect a Cash Tender for
               all their Common Limited Partner Units;

                             (4) Each Original Limited Partner (a) may effect an
               Exchange only once in each Twelve-Month Period, and (b) may not
               effect an Exchange or Cash Tender during the period after the
               Partnership Record Date with respect to a distribution and before
               the record date established by the General Partner for a
               distribution to its stockholders of some or all of its portion of
               such distribution.

                             (5) Notwithstanding anything herein to the
               contrary, with respect to any Cash Tender, in the event the
               General Partner gives notice to all Original Limited Partners
               then owning Common Limited Partner Interests (a "Primary Offering
               Notice") that it desires to effect a primary offering of its
               equity



                                       64

               securities then, unless the General Partner otherwise consents,
               commencement of the actions denoted in Section 8.6.E hereof as to
               a Public Offering Funding with respect to any Notice of Cash
               Tender thereafter received (a "Subsequent Cash Tender Notice")
               may be delayed until the earlier of (a) the completion of the
               primary offering or (b) 90 days following the giving of the
               Primary Offering Notice; provided to the extent that the managing
               underwriter(s) of such primary offering advise that the inclusion
               of such additional REIT Shares will not adversely affect the
               offering, additional REIT Shares the proceeds of which are to be
               used to satisfy a Cash Tender made subject to such a Subsequent
               Cash Tender Notice (a "Subsequent Cash Tender") (without regard
               to the limitations of subparagraph (3)(a) of this paragraph G)
               shall be included in such offering, and the procedures of this
               Section 8.6 shall otherwise be followed as closely as
               practicable; provided, further, unless the entire REIT Shares
               Amount relating to the Common Limited Partner Units made subject
               to the Subsequent Cash Tender shall be sold in such offering,
               such Subsequent Cash Tender shall not count as a Cash Tender for
               purposes of this Section 8.6; provided, further, a Primary
               Offering Notice may be given no more than once in any
               Twelve-Month Period without the Consent of the Common Limited
               Partners.

                             (6) No Common Limited Partner may effect a Cash
               Tender within 90 days following the closing of any prior Public
               Offering Funding;

                             (7) The consummation of such an Exchange or Cash
               Tender shall be subject to the expiration or termination of the
               applicable waiting period, if any, under the Hart-Scott-Rodino
               Antitrust Improvements Act of 1976, as amended.

                             (8) Each Tendering Partner shall continue to own
               all Common Limited Partner Units subject to any Exchange or Cash
               Tender, and be treated as a Common Limited Partner with respect
               to such Common Limited Partner Units for all purposes of this
               Agreement, until such Common Limited Partner Units are
               transferred to the General Partner and paid for on the Specified
               Exchange Date, or Specified Cash Tender Date, as the case may be.
               Until a Specified Exchange Date, the Tendering Partner shall have
               no rights as a stockholder of the General Partner with respect to
               the REIT Shares to be received in such Exchange.

                             (9) For purposes of determining compliance with the
               restrictions set forth in this Section 8.6.G, all Common Limited
               Partner Units beneficially owned by a Related Party of an
               Original Limited Partner shall be considered to be owned or held
               by such Limited Partner.

        H. The General Partner agrees to cause the REIT Shares issuable upon an
Exchange pursuant to this Section 8.6 to be listed on the New York Stock
Exchange prior to or



                                       65
<PAGE>   71

concurrently with the issuance of such REIT Shares by the General Partner. REIT
Shares issued upon an Exchange pursuant to this Section 8.6 may contain such
legends regarding compliance with the Securities Act and applicable state
securities laws as the General Partner in good faith determines to be necessary
in order to comply with applicable law.

        I. In connection with an exercise of Exchange Rights pursuant to this
Section 8.6, each Tendering Partner shall submit the following, in addition to
the Notice of Exchange:

        (1)    An affidavit, dated the same date as the Notice of Exchange,
               disclosing the ownership by (a) such Partner of REIT Shares and
               (b) any Person whose ownership of REIT Shares would be attributed
               to such Partner under Code Section 544 and a representation in
               writing that neither such Partner nor any Person from whom
               ownership of REIT Shares could be attributed to it under Code
               Section 544 has any intention as of such date of acquiring
               additional REIT Shares between the date of the Notice of Exchange
               and the Specified Exchange Date.

        (2)    If the Tendering Partner is a Related Party, the affidavit
               described in (1) above shall disclose the direct and constructive
               ownership pursuant to Section 544 of the Code of REIT Shares of
               all such Related Parties and shall provide the representation
               described in (1) with respect to such Partner and Related
               Partners.

        (3)    On the Specified Exchange Date, the Tendering Partner shall
               certify the (i) the direct and constructive ownership of REIT
               Shares by such Partner remains unchanged from the affidavit
               described above in (1) or (2) or (ii) if such ownership has
               changed, the Tendering Partner will not and will not be deemed to
               own REIT Shares of the General Partner in violation of the
               Ownership Limit.

        J. The provisions of this Section 8.6 insofar as they relate to an
Exchange (but not a Cash Tender) shall be applicable to the Common Limited
Partner Units owned by TRC and any TRC Shareholder to whom Common Limited
Partner Units have been Transferred as provided in Section 11.3, or to whom
Common Limited Partner Units have been issued, and TRC and such TRC Shareholder
shall have the right to effect an Exchange subject to and in accordance with
this Section 8.6, provided that:

        (1)    until such time as TRC or such TRC Shareholder holds less than
               10,000 Common Limited Partner Units, not more than one-third
               (1/3) of the aggregate number of Common Limited Partner Units
               that have been issued to TRC and the TRC Shareholders may be
               Exchanged during any Twelve-Month Period;

        (2)    none of such Common Limited Partner Units may be Exchanged prior
               to a date which is the earlier to occur of (i) February 4, 2000

               Clara County pursuant to California Civil Code Section 3093
               covering all improvements included in the Tandem Project;

        (3)    TRC or such TRC Shareholder may not effect an Exchange of less
               than 10,000 Common Limited Partner Units or, if TRC or such TRC
               Shareholder holds less than 10,000 Common Limited Partner Units,
               all of the Limited Partner Units held by TRC or such TRC
               Shareholder; and

        (4)    in the event TRC or a TRC Shareholder wishes to Exchange Common
               Limited Partner Units for REIT Shares, having complied with this
               Section 8.6, the General Partner (for its own account or for the
               account of its nominee) shall have the right, but not the
               obligation, to purchase all or a portion of such Common Limited
               Partner Units for cash at a price equal to the number of Common
               Limited Partner Units to be purchased pursuant to this Section
               8.6.J multiplied by the average of the Unit Values for the ten
               (10) trading days immediately preceding the date of purchase by
               the General Partner (or its nominee) of such Common Limited
               Partner Units. The General Partner shall exercise such right, if
               at all, within thirty (30) days of the date on which the General
               Partner receives a Notice of Exchange from TRC or a TRC
               Shareholder as to its desire to Exchange such Common Limited
               Partner Units for REIT Shares. In the event the General Partner
               purchases Common Limited Partner Units pursuant to this Section
               8.6.J, the Partnership will be deemed to have issued to the
               General Partner a number of General Partner Units equal to the
               number of Limited Partner Units so purchased, the Limited Partner
               Units so purchased shall be canceled and the Junior Percentage
               Interests of the General Partner and all Common Limited Partners
               shall be adjusted based on the foregoing.



                                    ARTICLE 9

                     BOOKS, RECORDS, ACCOUNTING AND REPORTS

        Section 9.1.  Records and Accounting

        The General Partner shall keep or cause to be kept at the principal
office of the Partnership those records and documents required to be maintained
by the Act and other books and records deemed by the General Partner to be
appropriate with respect to the Partnership's business, including, without
limitation, all books and records necessary to provide to the Limited Partners
any information, lists and copies of documents required to be provided pursuant
to Sections 8.5 or 9.2 hereof. The books of the Partnership shall be maintained,
for financial and tax reporting purposes, on an accrual basis in accordance with
generally accepted accounting



                                       67

principles, or on such other basis as the General Partner determines to be 
necessary or appropriate.

        Section 9.2.  Reports

        A. As soon as practicable, but in no event later than ninety (90) days
after the close of the last fiscal quarter of each Partnership Year, the General
Partner shall cause to be mailed to each Limited Partner, an annual report
containing financial statements of the Partnership for the Partnership Year, or
of the General Partner if such statements are prepared solely on a consolidated
basis with the General Partner, for the twelve month period ending December 31,
presented in accordance with generally accepted accounting principles, such
statements to be audited by a nationally recognized firm of independent public
accountants selected by the General Partner.

        B. As soon as practicable, but in no event later than forty five (45)
days after the close of each fiscal quarter (except the last fiscal quarter of
each year), the General Partner shall cause to be mailed to each Limited Partner
as of the last day of the calendar quarter, a report containing unaudited
financial statements of the Partnership, or of the General Partner if such
statements are prepared solely on a consolidated basis with the General Partner,
and such other information as may be required by applicable law or regulation or
as the General Partner determines to be appropriate. At the request of any
Limited Partner, the General Partner agrees to provide access to the books,
records and work papers upon which the reports in this Section 9.2. are based.



                                   ARTICLE 10

                                   TAX MATTERS

        Section 10.1. Preparation of Tax Returns; Tax Accounting

        The General Partner shall arrange for the preparation and timely filing
of all returns with respect to Partnership income, gains, deductions, losses and
other items required of the Partnership for federal and state income tax
purposes and shall use all reasonable efforts to furnish, on or before January
15 of each year (for so long as the Partnership Year is the fiscal year ending
December 31) the tax information, in draft or final form, reasonably required by
Limited Partners for federal and state income tax reporting purposes and
thereafter within fifteen (15) days of the end of the Partnership Year. In the
event that the General Partner delivers such information in draft form, the
General Partner shall use its best efforts to ascertain that any information
that would be used by any Partner for information reporting purposes is accurate
and complete. At the request of any Limited Partner, the General Partner agrees
to provide access to the books, records and work papers upon which the reports
in this Section 10.1. are based and to



                                       68
<PAGE>   74

provide access to financial and income tax data necessary for the Limited
Partners to determine quarterly estimated income tax payments required to be
paid by the Limited Partners.

        Section 10.2. Tax Elections

        Except as otherwise provided herein, the General Partner shall, in its
sole discretion, determine whether to make any available election pursuant to
the Code. The General Partner shall make the election under Section 754 of the
Code in accordance with applicable Regulations thereunder. The General Partner
shall elect, and shall file such returns and amended returns, as necessary, in a
manner consistent with the use of the recurring item method of accounting
provided under Section 461(h) of the Code with respect to property taxes imposed
on the Property of the Partnership, including causing the applicable property
taxes to be paid prior to the date provided under Section 461(h) for purposes of
economic performance. The General Partner shall have the right to seek to revoke
any such election (excluding the elections under Sections 461(h) and 754 of the
Code) upon the General Partner's determination in its sole discretion that such
revocation is in the best interests of the Partners.

        Section 10.3. Tax Matters Partner

        The General Partner shall be the "tax matters partner" of the
Partnership for federal income tax purposes. The tax matters partner shall
receive no compensation for its services. All third party costs and expenses
incurred by the tax matters partner in performing its duties as such (including
legal and accounting fees and expenses) shall be borne by the Partnership in
addition to any reimbursement pursuant to Section 7.4 hereof. Nothing herein
shall be construed to restrict the Partnership from engaging an accounting firm
to assist the tax matters partner in discharging its duties hereunder, so long
as the compensation paid by the Partnership for such services is reasonable. At
the request of any Limited Partner, the General Partner agrees to consult with
such Limited Partner with respect to the preparation and filing of any returns,
including, without limitation any subsequent audit or litigation with respect to
such return, provided the filing of such returns shall be in the sole discretion
of the General Partner, provided, however, that the Original Limited Partners
shall have the right, at their own expense, to contest any adjustment and
approve any settlement in connection with an item that was allocated to them
pursuant to Section 6.2.A.

        Section 10.4. Withholding

        Each Limited Partner hereby authorizes the Partnership to withhold from
or pay on behalf of or with respect to such Limited Partner any amount of
federal, state, local, or foreign taxes that the General Partner determines that
the Partnership is required to withhold or pay with respect to any amount
distributable or allocable to such Limited Partner pursuant to this Agreement,
including without limitation any taxes required to be withheld or paid by the
Partnership pursuant to Section 1441, 1442, 1445 or 1446 of the Code. Any amount
paid on behalf of or with respect to a Limited Partner shall constitute a loan
by the Partnership to such Limited



                                       69
<PAGE>   75

Partner, which loan shall be repaid by such Limited Partner within fifteen (15)
days after notice from the General Partner that such payment must be made unless
(i) the Partnership withholds such payment from a distribution which would
otherwise be made to the Limited Partner or (ii) the General Partner determines
that such payment may be satisfied out of the available funds of the Partnership
which would, but for such payment, be distributed to the Limited Partner. Any
amounts withheld pursuant to the foregoing clauses (i) or (ii) shall be treated
as having been distributed to such Limited Partner pursuant to Article 5 hereof.



                                   ARTICLE 11

              TRANSFERS AND WITHDRAWALS; REMOVAL OF GENERAL PARTNER

        Section 11.1. Transfer

        A. The term "Transfer," when used in this Article 11 with respect to a
Partnership Unit, shall be deemed to refer to a transaction by which the General
Partner purports to assign all or any part of its General Partner Interest to
another Person or by which a Limited Partner purports to assign all or any part
of its Limited Partner Interest to another Person. The term "Transfer" when used
in this Article 11 does not include any Exchange of Common Limited Partner Units
by an Original Limited Partner, TRC or a TRC Shareholder for REIT Shares of the
General Partner or acquisition of Common Limited Partner Units from a Common
Limited Partner by the General Partner pursuant to Section 8.6 or Section
11.3.F.

        B. No Partnership Interest shall be Transferred, in whole or in part,
except in accordance with the terms and conditions set forth in this Article 11.
Any Transfer or purported Transfer of a Partnership Interest not made in
accordance with this Article 11 shall be null and void.

        Section 11.2. Transfer of General Partner's Interest

        A. The General Partner may not Transfer any of its General Partner
Interest or withdraw as General Partner except as provided in Sections 11.2.B
and 11.2.C hereof.

        B. The General Partner shall not withdraw from the Partnership and shall
not Transfer, pledge, encumber or otherwise dispose of all or any portion of its
interest in the Partnership (whether by sale, disposition, statutory merger or
consolidation, liquidation or otherwise) without the Consent of the Common
Limited Partners. Upon any Transfer of such a Partnership Interest pursuant to
the Consent of the Common Limited Partners and otherwise in accordance with the
provisions of this Section 11.2.B, the transferee shall become a successor
General Partner for all purposes herein, and shall be vested with the powers and
rights of the transferor General Partner, and shall be liable for all
obligations and responsible for all duties of



                                       70
<PAGE>   76

the General Partner, once such transferee has executed such instruments as may
be necessary to effectuate such admission and to confirm the agreement of such
transferee to be bound by all the terms and provisions of this Agreement with
respect to the Partnership Interest so acquired. It is a condition to any such
Transfer that the transferee assumes, by operation of law or express agreement,
all of the obligations of the transferor General Partner under this Agreement
with respect to such transferred Partnership Interest, and no such Transfer
(other than pursuant to a statutory merger or consolidation wherein all
obligations and liabilities of the transferor General Partner are assumed by a
successor corporation by operation of law) shall relieve the transferor General
Partner of its obligations under this Agreement without the Consent of the
Common Limited Partners.

        C. Subject to the consent requirement in Section 7.3 hereof, the General
Partner may merge with another entity if immediately after such merger
substantially all of the assets of the surviving entity, other than the General
Partner Units held by the General Partner are contributed to the Partnership as
a Capital Contribution in exchange for the General Partner Units.

        Section 11.3. Limited Partners' Rights to Transfer

        A. A Limited Partner shall have the right to transfer all or any portion
of its Partnership Interest to any Person, subject to the provisions of Section
11.6 hereof and, in the case of Preferred Limited Partner Interests owned by IAC
Capital Trust, 11.3.E hereof; provided that, any Transfer of a Partnership
Interest shall be made only to a Qualified Transferee. Notwithstanding the
foregoing provisions of this Section 11.3, any Original Limited Partner may, at
any time, without the consent of the General Partner, (i) Transfer all or any
portion of its Partnership Interest to an Affiliate or to an Irvine Person,
subject to the provisions of Section 11.6 hereof, (ii) transfer all or a portion
of its Partnership Interest pursuant to its rights to effect an Exchange or a
Cash Tender as provided in Section 8.6 hereof and (iii) Pledge any portion of
its Partnership Interest. It is a condition to any Transfer otherwise permitted
hereunder that the transferee assumes by operation of law or express agreement
all of the obligations of the transferor Limited Partner under this Agreement
with respect to such transferred Partnership Interest and no such Transfer
(other than pursuant to a statutory merger or consolidation wherein all
obligations and liabilities of the transferor Limited Partner are assumed by a
successor corporation by operation of law) shall relieve the transferor Limited
Partner of its obligations under this Agreement without the approval of the
General Partner, in its sole discretion. Notwithstanding the foregoing, any
transferee of any transferred Partnership Interest shall be subject to any and
all ownership limitations contained in the Certificate of Incorporation which
may limit or restrict such transferee's ability to exercise its Exchange Rights.
Any transferee shall take subject to the obligations of the transferor
hereunder, but such transferee shall not be liable for the obligations of the
transferor under Section 17-607 of the Act. Any transferee that is an Original
Limited Partner shall be permitted to exercise the rights to effect an Exchange
or a Cash Tender as provided in Section 8.6 hereof. Unless a transferee is an
Original Limited Partner, TRC or a TRC Shareholder, such transferee shall not be
entitled to exercise the rights provided under Section 8.6 hereof in the absence
of consent by the General Partner. Until



                                       71
<PAGE>   77

admitted as a Substituted Limited Partner, no transferee, whether by a voluntary
transfer, by operation of law or otherwise, shall have any rights hereunder,
other than the rights of an Assignee as provided in Section 11.5 hereof.

        B. If a Limited Partner is subject to Incapacity, the executor,
administrator, trustee, committee, guardian, conservatory or receiver of such
Limited Partner's estate shall have all the rights of a Limited Partner, but not
more rights than those enjoyed by other Limited Partners of the same class or
series, for the purpose of settling or managing the estate, and such power as
the Incapacitated Limited Partner possessed to transfer all or any part of his
or its interest in the Partnership. The Incapacity of a Limited Partner, in and
of itself, shall not dissolve or terminate the Partnership.

        C. In connection with any Transfer, the General Partner shall have the
right to receive an opinion of counsel reasonably satisfactory to it to the
effect that the proposed Transfer may be effected without registration under the
Securities Act and will not otherwise violate any federal or state securities
laws or regulations applicable to the Partnership or the Partnership Interests
transferred. If, in the opinion of such counsel, such Transfer would require the
filing of a registration statement under the Securities Act or would otherwise
violate any federal or state securities laws or regulations applicable to the
Partnership or the Partnership Units, the General Partner may prohibit any
Transfer otherwise permitted under this Section 11.3 by a Limited Partner of
Partnership Interests.

        D. No Transfer by a Limited Partner of its Partnership Interests
(including any Exchange or Cash Tender, any other acquisition of Partnership
Units by the General Partner or any acquisition of Partnership Units by the
Partnership) may be made to any person if (i) in the opinion of legal counsel
for the Partnership, it would result in the Partnership being treated as an
association taxable as a corporation, or (ii) such Transfer is effectuated
through an "established securities market" or a "secondary market (or the
substantial equivalent thereof)" within the meaning of Section 7704 of the Code.

        E. In addition to the restrictions on Transfer set forth in this Section
11.3 and in Section 11.6 and notwithstanding anything to the contrary contained
in this Agreement, no Preferred Limited Partner Interest of any series owned by
IAC Capital Trust may be Transferred except in accordance with the Designation
Instrument creating such series.

        F. In addition to the restrictions on Transfer set forth in the
foregoing provisions of this Section 11.3 and in Section 11.6, a Transfer of all
or any portion of the Partnership Interest of TRC shall be subject to the
following additional provisions:

                      (1) None of such Partnership Interest may be Transferred
               except (i) to any one, or any combination of, William W.
               Thompson, Bruce Dorfman or Robert Hughes (individually, a "TRC
               Shareholder", and collectively, the "TRC Shareholders"), provided
               that it shall be a condition precedent to any such



                                       72
<PAGE>   78

               Transfer and the admission of the TRC Shareholder as a
               Substituted Limited Partner that such TRC Shareholder agree in
               writing to be bound by the restrictions on Transfer set forth in
               this Agreement or (ii) to the General Partner (or its nominee) as
               contemplated by this Section 11.3.F.

                      (2) In the event all or any portion of such Partnership
               Interest is Transferred to a TRC Shareholder and a TRC
               Shareholder Incapacity occurs with respect to such TRC
               Shareholder, TRC shall within thirty (30) days notify the General
               Partner of such TRC Shareholder Incapacity and the General
               Partner shall have the right, but not the obligation, to purchase
               (for its own account or for the account of its nominee) the
               Partnership Interest of such TRC Shareholder for cash at a price
               equal to the number of Common Limited Partner Units representing
               the Partnership Interest of such TRC Shareholder multiplied by
               the average of the Unit Values for the ten (10) trading days
               immediately preceding the date of purchase by the General Partner
               (or its nominee) of such Partnership Interest. The General
               Partner shall exercise such right, if at all, within thirty (30)
               days of the date on which the General Partner receives written
               notice of such TRC Shareholder Incapacity. If the General Partner
               fails to exercise such right, such Common Limited Partner Units
               must, within 90 days of such TRC Shareholder Incapacity, and, in
               all events, prior to any Transfer to the heirs or devisees of
               such TRC Shareholder or to any other Person, be Exchanged for
               REIT Shares in accordance with Section 8.6, in which event the
               conditions to an Exchange set forth in the proviso in Section
               8.6.J shall not apply to the right to Exchange such Common
               Limited Partner Units for REIT Shares.

                      (3) In the event of the death of, or total physical
               disability of, a TRC Shareholder, entry by a court of competent
               jurisdiction adjudicating such TRC Shareholder incompetent to
               manage his person or his estate, or an Act of Bankruptcy with
               respect to such TRC Shareholder ("TRC Shareholder Incapacity"),
               TRC shall within thirty (30) days notify the General Partner of
               such TRC Shareholder Incapacity, and if such TRC Shareholder
               Incapacity relates to a TRC Shareholder other than William W.
               Thompson, and if at the time of such TRC Shareholder Incapacity
               TRC is a Partner, then:

                             (i) TRC shall have the right, but not the
                      obligation to satisfy the General Partner, in its sole
                      discretion and within thirty (30) days of the occurrence
                      of such TRC Shareholder Incapacity, that such TRC
                      Shareholder Incapacity will not result, at any time, in
                      any portion of TRC's Partnership Interest being
                      Transferred, directly or indirectly, to the TRC
                      Shareholder with respect to whom such TRC Shareholder
                      Incapacity occurred.



                                       73
<PAGE>   79

                             (ii) In the event TRC fails to so satisfy the
                      General Partner, the General Partner shall have the right,
                      but not the obligation, to purchase (for its own account
                      or for the account of its nominee) a portion of TRC's
                      Partnership Interest for cash at a price equal to the
                      number of the Common Limited Partner Units which the
                      General Partner is entitled to purchase pursuant to this
                      Section 11.3.F(3)(ii) multiplied by the average of the
                      Unit Values for the ten (10) trading days immediately
                      preceding the date of such purchase by the General Partner
                      (or its nominee). The number of Common Limited Partner
                      Units which the General Partner shall be entitled to
                      purchase pursuant to this Section 11.3.F(3)(ii) shall be
                      equal to the total number of Common Limited Partner Units
                      then owned by TRC, multiplied by a fraction, the
                      denominator of which shall be the total number of TRC
                      Shares outstanding as of the time of such TRC Shareholder
                      Incapacity and the numerator of which shall be the total
                      number of TRC Shares owned by the TRC Shareholder at the
                      time of such TRC Shareholder Incapacity. The General
                      Partner shall exercise such right, if at all, within
                      thirty (30) days of the date on which the General Partner
                      receives written notice of such TRC Shareholder
                      Incapacity.

                             (iii) If TRC fails to so satisfy the General
                      Partner and the General Partner fails to exercise its
                      right of purchase as set forth in clause (ii) above,
                      Common Limited Partner Units in the amount which the
                      General Partner was entitled to purchase pursuant to
                      clause (ii) must, within 90 days of time of such TRC
                      Shareholder Incapacity, be Exchanged for REIT Shares, in
                      which event the conditions to an Exchange set forth in the
                      proviso in Section 8.6.J shall not apply to the right to
                      Exchange such Common Limited Partner Units for REIT
                      Shares.

                             (iv) From and after the date on which the General
                      Partner purchases such Common Limited Partner Units
                      pursuant to clause (ii) or such Common Limited Partner
                      Units are Exchanged for REIT Shares pursuant to clause
                      (iii), TRC shall take such steps as may be necessary, as
                      determined by the General Partner in its sole discretion,
                      to ensure that any Common Limited Partner Units still
                      owned by TRC shall not, at any time, without the prior
                      written consent of the General Partner, be Transferred to
                      the estate, heirs or devisees of the TRC Shareholder who
                      is then subject to a TRC Shareholder Incapacity or to any
                      other Person.

                      (4) In the event of a TRC Shareholder Incapacity with
               respect to William W. Thompson, if at the time of such TRC
               Shareholder Incapacity, TRC is a Partner, TRC shall within thirty
               (30) days notify the General Partner of such TRC Shareholder
               Incapacity and the General Partner shall have the right, but not
               the obligation, to purchase (for its own account or for the
               account of its nominee)



                                       74
<PAGE>   80

               all or any portion of TRC's Partnership Interest for cash at a
               price equal to the number of Common Limited Partner Units
               representing such TRC Partnership Interest multiplied by the
               average of the Unit Values for the ten (10) trading days
               immediately preceding the date of purchase by the General Partner
               (or its nominee) of such Partnership Interest. The General
               Partner shall exercise such right, if at all, within thirty (30)
               days of the date on which the General Partner receives written
               notice of such TRC Shareholder Incapacity. If the General Partner
               fails to exercise such right, such Common Limited Partner Units
               must, within 90 days of such TRC Shareholder Incapacity, be
               Exchanged for REIT Shares, in which event the conditions to an
               Exchange set forth in the proviso in Section 8.6.J shall not
               apply to the right to Exchange such Common Limited Partner Units
               for REIT Shares.

                      (5) In the event of an Act of Bankruptcy with respect to
               TRC, the General Partner shall have the right, but not the
               obligation, to purchase (for its own account or for the account
               of its nominee) all or any portion of TRC's Partnership Interest
               for cash at a price equal to the number of Common Limited Partner
               Units representing such TRC Partnership Interest multiplied by
               the average of the Unit Values for the ten (10) trading days
               immediately preceding the date of purchase by the General Partner
               (or its nominee) of such Partnership Interest. The General
               Partner shall exercise such right, if at all, within thirty (30)
               days of the date on which the General Partner receives written
               notice of such Act of Bankruptcy. If the General Partner fails to
               exercise such right, such Common Limited Partner Units must,
               within a reasonable period of time of such Act of Bankruptcy, be
               Exchanged for REIT Shares, in which event the conditions to an
               Exchange set forth in the proviso in Section 8.6.J shall not
               apply to the right to Exchange such Common Limited Partner Units
               for REIT Shares.

                      (6) In the event the General Partner purchases Common
               Limited Partner Units pursuant to clauses (2), (3), (4) or (5) of
               this Section 11.3.F, the Partnership will be deemed to have
               issued to the General Partner a number of General Partner Units
               equal to the number of Common Limited Partner Units so purchased,
               the Common Limited Partner Units so purchased shall be canceled
               and the Junior Percentage Interest of the General Partner and all
               Common Limited Partners shall be adjusted based on the foregoing.

        G. In addition to the restrictions on Transfer set forth in the
foregoing provisions of this Section 11.3 and in Section 11.6, a Transfer of all
or any portion of the Partnership Interest of a TRC Shareholder shall be subject
to the following additional provision:

                      (1) None of such Partnership Interest may be Transferred
               by such TRC Shareholder, except (i) to another TRC Shareholder in
               compliance with all applicable laws and regulations and the terms
               and conditions of this Agreement,



                                       75
<PAGE>   81

               (ii) a Transfer by operation of law as a result of a TRC
               Shareholder Incapacity, in which event the provisions of Section
               11.3.F(2) shall apply and (iii) to the General Partner or its
               nominee as contemplated by Section 11.3.F.

        Section 11.4. Substituted Limited Partners

        A. Each Limited Partner shall, pursuant to the provisions of 11.3, have
the right to Transfer all or a portion of its Partnership Interest to any
Person, subject in the case of Preferred Limited Partner Interests owned by IAC
Capital Trust to Section 11.3.E. Upon satisfaction of the conditions provided
under Section 3.4 and Section 11.3 and upon furnishing to the General Partner
(i) evidence of acceptance in form satisfactory to the General Partner of all of
the terms and conditions of this Agreement, including, without limitation, the
power of attorney granted in Section 2.4 hereof, (ii) a counterpart signature
page to this Agreement executed by such Person and (iii) such other documents or
instruments as may be required in the discretion of the General Partner in order
to effect such Person's admission as a Substituted Limited Partner, the General
Partner shall promptly admit such transferee of the interest of a Limited
Partner as a Substituted Limited Partner.

        B. A transferee who has been admitted as a Substituted Limited Partner
in accordance with this Article 11 shall have all the rights and powers and be
subject to all the restrictions and liabilities of a Limited Partner under this
Agreement.

        C. Upon the admission of a Substituted Limited Partner, the General
Partner shall amend Exhibit A to reflect the name, address, number of Limited
Partner Units, and Percentage Interest of such Substituted Limited Partner and
to eliminate or adjust, if necessary, the name, address and interest of the
predecessor of such Substituted Limited Partner.

        Section 11.5. Assignees

        Until such time as a transferee has been admitted as a Substituted
Limited Partner pursuant to Section 11.4, such transferee shall be considered an
Assignee for purposes of this Agreement. An Assignee shall be deemed to have had
assigned to it, and shall be entitled to receive, distributions from the
Partnership and the share of Net Income, Net Losses, and any other items of
income, gain, loss, deduction and credit of the Partnership attributable to the
Limited Partner Units assigned to such transferee, but shall not be deemed to be
a holder of Limited Partner Units for any other purpose under this Agreement,
and shall not be entitled to vote such Limited Partner Units in any matter
presented to the Limited Partners of the same class or series for a vote (such
Limited Partner Units being deemed to have been voted on such matter in the same
proportion as all other Limited Partner Units held by Limited Partners of the
same class or series are voted). In the event any such transferee desires to
make a further assignment of any such Partnership Units, such transferee shall
be subject to all the provisions of this Article 11 to the same extent and in
the same manner as any Limited Partner desiring to make an assignment of Limited
Partner Units.

        Section 11.6. General Provisions

        A. No Limited Partner may withdraw from the Partnership other than as a
result of a permitted Transfer of all of such Limited Partner's Limited Partner
Units in accordance with this Article 11 or pursuant to an Exchange or a Cash
Tender of all of its Common Limited Partner Units under Section 8.6 hereof.

        B. Any Limited Partner who shall Transfer all of his Limited Partner
Units in a transfer permitted pursuant to this Article 11 shall cease to be a
Limited Partner upon the admission of all Assignees of such Limited Partner
Units as Substituted Limited Partners. Similarly, (i) any Common Limited Partner
who shall transfer all of its Common Limited Partner Units pursuant to an
Exchange or Cash Tender of all of its Common Limited Partner Units under Section
8.6 hereof shall cease to be a Common Limited Partner and (ii) any Preferred
Limited Partner whose Preferred Limited Partner Units of a series are redeemed
in full or paid in full upon the stated maturity thereof, in each case, in
accordance with the Designation Instrument applicable to such series of
Partnership Units shall cease to be a Preferred Limited Partner insofar as such
series is concerned.

        C. If any Partnership Unit is Transferred during any quarterly segment
of the Partnership Year in compliance with the provisions of this Article 11, or
Exchanged or Cash Tendered pursuant to Section 8.6 hereof, on any day other than
the first day of a Partnership Year, then Net Income, Net Losses, each item
thereof and all other items attributable to such Partnership Unit for such
Partnership Year shall be allocated to the transferor Partner or the Tendering
Partner, as the case may be, and, in the case of a transfer or assignment other
than an Exchange or a Cash Tender, to the transferee Partner, by taking into
account their varying interests during the Partnership Year in accordance with
Section 706(d) of the Code, using the interim closing of the books method.
Solely for purposes of making such allocations, each of such items for the
calendar month in which a transfer occurs shall be allocated to the transferee
Partner and none of such items for the calendar month in which a transfer or an
Exchange occurs shall be allocated to the transferor Partner or the Tendering
Partner, as the case may be, if such transfer occurs before the fifteenth day of
the month, otherwise such items shall be allocated to the transferor. All
distributions of Available Cash attributable to such Partnership Unit with
respect to which the Partnership Record Date is before the date of such
transfer, assignment, Exchange or Cash Tender shall be made to the transferor
Partner or the Tendering Partner, as the case may be, and, in the case of a
transfer other than an Exchange or a Cash Tender, all distributions of Available
Cash thereafter attributable to such Partnership Unit shall be made to the
transferee Partner.

        D. In addition to any other restriction on transfer herein contained, in
no event may any transfer or assignment of a Partnership Interest by any Partner
(including any Exchange or Cash Tender or any other acquisition of Partnership
Units by the General Partner) be made (i) to any person or entity who lacks the
legal right, power or capacity to own a Partnership Interest; (ii) in violation
of applicable law; (iii) of any component portion of a Partnership Interest,
such as the



                                       77
<PAGE>   83

Capital Account, or rights to distributions, separate and apart from all other
components of a Partnership Interest, (iv) in the event such transfer would
cause the General Partner to cease to comply with the requirements for REIT
status under the Code, (v) if such transfer would, in the opinion of counsel to
the Partnership, cause the Partnership to cease to be classified as a
partnership for Federal income tax purposes (except as a result of the Exchange
or Cash Tender of all Common Limited Partner Units held by all Common Limited
Partners); (vi) if such transfer would cause the Partnership to become, with
respect to any employee benefit plan subject to Title I of ERISA, a
"party-in-interest" (as defined in Section 3(14) of ERISA) or a "disqualified
person" (as defined in Section 4975(c) of the Code); (vii) if such transfer
would, in the opinion of counsel to the Partnership, cause any portion of the
assets of the Partnership to constitute assets of any employee benefit plan
pursuant to Department of Labor Regulations Section 2510.2-101; (viii) if such
transfer requires the registration of such Partnership Interest pursuant to any
applicable federal or state securities laws; (ix) if such transfer requires the
Partnership to become a reporting company under the Securities Exchange Act of
1934; or (x) if such transfer subjects the Partnership to be regulated under the
Investment Company Act of 1940, the Investment Advisors Act of 1940 or the
Employee Retirement Income Security Act of 1974, each as amended.

        Section 11.7.  Removal of General Partner

        A. The General Partner may not be removed as general partner except as
provided in this Section 11.7. The General Partner may be removed upon the
affirmative vote of Common Limited Partners holding 50% or more of the issued
and outstanding Common Limited Partner Interests if such removal is for cause.
As used in this Section 11.7, "cause" means an act or omission undertaken with
deliberate intent to cause injury to the Partnership, constituting actual fraud,
actual bad faith or willful misconduct on the part of the General Partner or an
act or omission of gross negligence. The right to remove the General Partner
shall not exist or be exercised unless such action for removal also provides for
the election of a new general partner. Such removal shall be effective
immediately subsequent to the admission of the successor General Partner
pursuant to Article 12 hereof.

        B. Upon the removal of the General Partner, the departing General
Partner shall become a Common Limited Partner, and its General Partner Interest
shall be converted automatically into a Common Limited Partner Interest, without
any reduction in the departing General Partner's Junior Percentage Interest
(subject to proportionate dilution by reason of the admission of its successor).

        This Agreement shall be amended to reflect any event described in this
Section 11.7, and any successor General Partner covenants so to amend this
Agreement and the Certificate, as required.

        C. The successor to the departing General Partner shall at the effective
date of its admission to the Partnership contribute to the capital of the
Partnership cash in an amount such



                                       78
<PAGE>   84

that its Capital Account, after giving effect to such contribution, shall be at
least equal to the amount, if any, required by any applicable law.

        D. The removal of the General Partner pursuant to this Section 11.7 will
not relieve the Partnership from any of its debts or other obligations to the
departing General Partner, including, without limitation, reimbursement
obligations under Section 7.4 or its obligations under Section 7.7, arising
prior to the removal of the departing General Partner.



                                   ARTICLE 12

                              ADMISSION OF PARTNERS

        Section 12.1. Admission of Successor General Partner

        A successor to all of the General Partner Interest pursuant to Section
11.2.B hereof who is proposed to be admitted as a successor General Partner
shall be admitted to the Partnership as the General Partner, effective
immediately prior to such Transfer. A successor to a General Partner removed
pursuant to Section 11.7 shall be admitted to the Partnership as the successor
General Partner effective upon satisfaction of the condition specified in
Section 11.7.C. Any such successor shall carry on the business of the
Partnership without dissolution. In each case, the admission shall be subject to
the successor General Partner executing and delivering to the Partnership an
acceptance of all of the terms and conditions of this Agreement and such other
documents or instruments as may be required to effect the admission.

        Section 12.2. Admission of Additional Limited Partners

        A. A Person who makes a Capital Contribution to the Partnership on or
after the date hereof in accordance with this Agreement shall be admitted to the
Partnership as an Additional Limited Partner by the General Partner, without the
consent of any other Partner, only upon furnishing to the General Partner (i)
evidence of acceptance in form satisfactory to the General Partner of all of the
terms and conditions of this Agreement, including, without limitation, the power
of attorney granted in Section 2.4 hereof, (ii) a counterpart signature page to
this Agreement executed by such Person and (iii) such other documents or
instruments as may be required in the discretion of the General Partner in order
to effect such Person's admission as an Additional Limited Partner.

        B. Notwithstanding anything to the contrary in this Section 12.2, no
Person shall be admitted as an Additional Limited Partner without the consent of
the General Partner, which consent may be given or withheld in the General
Partner's sole discretion. The admission of any Person as an Additional Limited
Partner shall become effective on the date upon which the name



                                       79
<PAGE>   85

of such Person is recorded on the books and records of the Partnership,
following the consent of the General Partner to such admission.

        C. If any Additional Limited Partner is admitted to the Partnership on
any day other than the first day of a Partnership Year, then Net Income, Net
Losses, each item thereof and all other items allocable among Partners and
Assignees for such Partnership Year shall be allocated among such Additional
Limited Partner and all other Partners and Assignees by taking into account
their varying interests during the Partnership Year in accordance with Section
706(d) of the Code, using the interim closing of the books method. Solely for
purposes of making such allocations, each of such items for the calendar month
in which an admission of any Additional Limited Partner occurs shall be
allocated among all the Partners and Assignees including such Additional Limited
Partner, in accordance with the principles described in Section 11.6.C. All
distributions of Available Cash with respect to which the Partnership Record
Date is before the date of such admission shall be made solely to Partners and
Assignees other than the Additional Limited Partner, and all distributions of
Available Cash thereafter shall be made to all the Partners and Assignees
including such Additional Limited Partner.

        Section 12.3. Amendment of Agreement and Certificate of Limited 
Partnership

        For the admission to the Partnership of any Partner, the General Partner
shall take all steps necessary and appropriate under the Act to amend the
records of the Partnership and, if necessary, to prepare as soon as practical an
amendment of this Agreement (including an amendment of Exhibit A) and, if
required by law, shall prepare and file an amendment to the Certificate and may
for this purpose exercise the power of attorney granted pursuant to Section 2.4
hereof.

        Section 12.4.   Limit on Number of Partners

        No Person shall be admitted to the Partnership as an additional Partner
if the effect of such admission would be to cause the Partnership to have more
than 500 Partners, including as Partners for this purpose those Persons
indirectly owning an interest in the Partnership through another partnership,
subchapter S corporation or a grantor trust, or otherwise cause the Partnership
to become a reporting company under the Securities Exchange Act of 1934, as
amended.

<PAGE>   86

        The Partnership shall not be dissolved by the admission of Substituted
Limited Partners or Additional Limited Partners or by the admission of a
successor General Partner in accordance with the terms of this Agreement. Upon
the withdrawal or removal of the General Partner, any successor General Partner
shall continue the business of the Partnership without dissolution. The
Partnership shall dissolve, and its affairs shall be wound up, upon the first to
occur of any of the following ("Liquidating Events"):

                      A. the expiration of its term as provided in Section 2.5 
               hereof;

                      B. an event of withdrawal of the General Partner, as
               defined in the Act, unless, within ninety (90) days after the
               event of withdrawal (i) all the Common Limited Partners agree in
               writing to continue the business of the Partnership and to the
               appointment, effective as of the date of such event of
               withdrawal, of a successor General Partner; and (ii) more than
               fifty percent (50%) of the Percentage Interests of each series of
               Preferred Limited Partner Units then outstanding agree to
               continue the business of the Partnership either in writing or by
               vote at a meeting of Preferred Limited Partners held in
               accordance with Section 14.3 and to the appointment, effective as
               of the date of such event of withdrawal, of a successor General
               Partner;

                      C. an election to dissolve the Partnership made by the
               General Partner, subject to the Consent of the Common Limited
               Partners;

                      D. entry of a decree of judicial dissolution of the
               Partnership pursuant to the provisions of the Act;

               or

                      E. the sale of all or substantially all of the assets and
               properties of the Partnership.

        Section 13.2. Winding Up

        A. Upon the occurrence of a Liquidating Event, the Partnership shall
continue solely for the purposes of winding up its affairs in an orderly manner,
liquidating its assets, and satisfying the claims of its creditors and Partners.
No Partner shall take any action that is inconsistent with, or not necessary to
or appropriate for, the winding up of the Partnership's business and affairs.
The General Partner or, in the event there is no remaining General Partner, any
Person elected by the Common Limited Partners holding in the aggregate more than
fifty percent (50%) of the Percentage Interests of the Common Limited Partners
or, in the event there is no remaining General Partner or Common Limited
Partner, any Person elected by the Preferred Limited Partners holding in the
aggregate more than fifty percent (50%) of the Percentage Interests of the
Preferred Limited Partners voting as one class (the General Partner or



                                       81
<PAGE>   87

such other Person being referred to herein as the "Liquidator") shall be
responsible for overseeing the winding up and dissolution of the Partnership and
shall take full account of the Partnership's liabilities and property and the
Partnership property shall be liquidated as promptly as is consistent with
obtaining the fair value thereof, and the proceeds therefrom (which may, to the
extent determined by the General Partner, include shares of stock in the General
Partner) shall be applied and distributed in the following order:

        (1)    First, to the satisfaction of all of the Partnership's debts and
               liabilities to creditors other than the Partners (whether by
               payment or the making of reasonable provision for payment
               thereof);

        (2)    Second, to the satisfaction of all of the Partnership's debts and
               liabilities to the General Partner (whether by payment or the
               making of reasonable provision for payment thereof);

        (3)    Third, to the satisfaction of all of the Partnership's debts and
               liabilities to the other Partners (whether by payment or the
               making of reasonable provision for payment thereof);

        (4)    Fourth, to the Preferred Limited Partners, the applicable
               Liquidation Preference Amount; and

        (5)    The balance, if any, to the General Partner and Common Limited
               Partners in accordance with their Capital Accounts, after giving
               effect to all contributions, distributions, and allocations for
               all periods.

        The General Partner shall not receive any additional compensation for
any services performed pursuant to this Article 13 other than reimbursement of
its expenses as provided in Section 7.4 hereof.

        B. Notwithstanding the provisions of Section 13.2.A hereof which require
liquidation of the assets of the Partnership, but subject to the order of
priorities set forth therein, if prior to or upon dissolution of the Partnership
the Liquidator determines that an immediate sale of part or all of the
Partnership's assets would be impractical or would cause undue loss to the
Partners, the Liquidator may, in its sole discretion, defer for a reasonable
time the liquidation of any assets except those necessary to satisfy liabilities
of the Partnership (including to those Partners as creditors) and/or distribute
to the Partners, in lieu of cash, as tenants in common and in accordance with
the provisions of Section 13.2.A hereof, undivided interests in such Partnership
assets as the Liquidator deems not suitable for liquidation. Any such
distributions in kind shall be made only if, in the good faith judgment of the
Liquidator, such distributions in kind are in the best interest of the Partners,
and shall be subject to such conditions relating to the disposition and
management of such properties as the Liquidator deems reasonable and equitable
and to any agreements governing the operation of such properties at such time.
The Liquidator shall



                                       82
<PAGE>   88


determine the fair market value of any property distributed in kind using such
reasonable method of valuation as it may adopt.

        C. In the event the Partnership is "liquidated" within the meaning of
Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made pursuant
to this Article 13 to the General Partner and Limited Partners who have positive
Capital Accounts in compliance with Regulations Section 1.704-1(b)(2)(ii)(b)(2)
to the extent of, and in proportion to, positive Capital Account balances. If
any Partner has a deficit balance in his Capital Account (after giving effect to
all contributions, distributions and allocations for all taxable years,
including the year during which such liquidation occurs), such Partner shall
have no obligation to make any contribution to the capital of the Partnership
with respect to such deficit, and such deficit shall not be considered a debt
owed to the Partnership or to any other Person for any purpose whatsoever. A pro
rata portion of the distributions that would otherwise be made to the General
Partner and Limited Partners pursuant to this Article 13 may be withheld or
escrowed to provide a reasonable reserve for Partnership liabilities (contingent

within thirty (30) days thereafter, provide written notice thereof to each of
the Partners.

                                       83
<PAGE>   89

other than the State of Delaware shall be canceled and such other actions as may
be necessary to terminate the Partnership shall be taken.

        A reasonable time shall be allowed for the orderly winding-up of the
business and affairs of the Partnership and the liquidation of its assets
pursuant to Section 13.2 hereof, in order to minimize any losses otherwise
attendant upon such winding-up, and the provisions of this Agreement shall
remain in effect between the Partners during the period of liquidation.

                                   ARTICLE 14

                  AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS

        Section 14.1. Amendments

        Amendments to this Agreement may be proposed by the General Partner or
by a Majority-In-Interest of the Common Limited Partners. Following such
proposal, the General Partner shall submit any proposed amendment to the Common
Limited Partners. The General Partner shall seek the written vote of the Common
Limited Partners on the proposed amendment or shall call a meeting to vote
thereon and to transact any other business that it may deem appropriate. For
purposes of obtaining a written vote, the General Partner may require a response
within a reasonable specified time, but not less than fifteen (15) days, and
failure to respond in such time period shall constitute a vote which is
consistent with the General Partner's recommendation with respect to the
proposal. Except as provided in Section 7.3.B, 7.3.C or 7.3.D hereof, a proposed
amendment shall be adopted and be effective as an amendment hereto if it is
approved by the General Partner and it receives the Consent of Common Limited
Partners.

        Section 14.2. Meetings of the Common Limited Partners

        A. Meetings of the Common Limited Partners may be called by the General
Partner and shall be called upon the receipt by the General Partner of a written
request by a Majority-In- Interest of the Common Limited Partners. The call
shall state the nature of the business to be transacted. Notice of any such
meeting shall be given to all Common Limited Partners not less than seven (7)
days nor more than thirty (30) days prior to the date of such meeting. Partners
may vote in person or by proxy at such meeting. Whenever the vote or Consent of
Common Limited Partners is permitted or required under this Agreement, such vote
or Consent may be



                                       84
<PAGE>   90


given at a meeting of Common Limited Partners or may be given in accordance with
the procedure prescribed in Section 14.2.B hereof.

        B. Any action required or permitted to be taken at a meeting of the
Common Limited Partners may be taken without a meeting if a written consent
setting forth the action so taken is signed by a majority of the Percentage
Interests of the Common Limited Partners (or such other percentage as is
expressly required by this Agreement). Such consent may be in one instrument or
in several instruments, and shall have the same force and effect as a vote of a
majority of the Percentage Interests of the Common Limited Partners (or such
other percentage as is expressly required by this Agreement). Such consent shall
be filed with the General Partner. An action so taken shall be deemed to have
been taken at a meeting held on the effective date so certified.

        C. Each Common Limited Partner may authorize any Person or Persons to
act for him by proxy on all matters in which a Common Limited Partner is
entitled to participate, including waiving notice of any meeting, or voting or
participating at a meeting. Every proxy must be signed by the Common Limited
Partner or his attorney-in-fact. No proxy shall be valid after the expiration of
eleven (11) months from the date thereof unless otherwise provided in the proxy
(or there is receipt of a proxy authorizing a later date). Every proxy shall be
revocable at the pleasure of the Common Limited Partner executing it, such
revocation to be effective upon the Partnership's receipt of written notice of
such revocation from the Common Limited Partner executing such proxy.

        D. Each meeting of Common Limited Partners shall be conducted by the
General Partner or such other Person as the General Partner may appoint pursuant
to such rules for the conduct of the meeting as the General Partner or such
other Person deems appropriate in his sole discretion. Without limitation,
meetings of Common Limited Partners may be conducted in the same manner as
meetings of the shareholders of the General Partner and may be held at the same
time, and as part of, meetings of the shareholders of the General Partner.

        Section 14.3.  Meetings of Preferred Limited Partners

        In the event that the vote or consent of the holders of Preferred
Limited Partner Interests (or any series thereof) is required pursuant to this
Agreement (including pursuant to a Designation Instrument) such vote or consent
may be obtained at a meeting of Preferred Limited Partners or by written
consent. The provisions of Section 14.2 hereof shall apply to any such meeting
or written consent to the extent practicable in which case all references in
such Section to Common Limited Partners shall mean the Preferred Limited
Partners as a class or the



                                       85
<PAGE>   91

Preferred Limited Partners holding the applicable series of Preferred Limited
Partner Interests, as shall be applicable to such vote or consent.

                          DESIGNATIONS, PREFERENCES AND
                      RELATIVE, PARTICIPATING, OPTIONAL OR
                    OTHER SPECIAL RIGHTS AND QUALIFICATIONS,
                       LIMITATIONS OR RESTRICTIONS OF THE
                    SERIES A PREFERRED LIMITED PARTNER UNITS


        FIRST: Pursuant to authority expressly vested in the General Partner of
the Partnership pursuant to Section 4.5.F of the Agreement, the General Partner
hereby classifies 6,900,000 Preferred Limited Partner Units of the Partnership
into a series designated the Series A Preferred Limited Partner Units and
provides for the issuance of such Preferred Limited Partner Units. This
instrument constitutes a Designation Instrument under the Agreement. Capitalized
terms used but not defined herein have the meanings set forth in the Agreement.

        SECOND: The terms of the Series A Preferred Limited Partner Units
established by this Designation Instrument are as follows:

        SECTION 1. Designation and Amount. The series of Preferred Limited
Partner Units shall be designated the "Series A Preferred Limited Partner Units"
and the authorized number of Partnership Units constituting such series shall be
6,900,000.

        SECTION 2. Stated Value. The stated value of the Series A Preferred
Limited Partner Units shall be $25.00 per Unit (the "STATED VALUE").

        SECTION 3. Distributions. (a) Subject to the rights of holders of any
series of Preferred Limited Partner Units which the Partnership may issue in the
future which rank on a parity with the Series A Preferred Limited Partner Units
in respect of distributions, the holders of outstanding Series A Preferred
Limited Partner Units will be entitled to receive, when, as and if declared by
the
<PAGE>   2



Partnership acting through the General Partner out of funds legally available
for the payment of distributions, cumulative preferential cash distributions at
the rate per annum of ____% of the Stated Value. Distributions will be
cumulative, will accrue from _________, 199_, the original issue date of the
Series A Preferred Limited Partner Units, and will be payable quarterly in
arrears on ________, _______, ________ and _______ (each a "SERIES A
DISTRIBUTION PAYMENT DATE") of each year, commencing on ________, 1998. The
amount of distributions payable for any period will be computed on the basis of
a 360-day year of twelve 30-day months and for any period shorter than a full
quarterly period for which distributions are computed, the amount of the
distribution payable will be computed on the basis of the actual number of days
elapsed in such a 30-day month. If any Series A Distribution Payment Date is not
a Business Day, the payment of the distribution to be made on such Series A
Distribution Payment Date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay) except that if such Business Day is in the next succeeding calendar year,
such payment shall be made on the immediately preceding Business Day, in each
case with the same force and effect as if made on such Series A Distribution
Payment Date. Each such distribution will be payable to the holders of record of
the Series A Preferred Limited Partner Units as they appear on the books of the
Partnership or any transfer agent for the Series A Preferred Limited Partner
Units on such record dates selected by the General Partner, not less than 10 nor
more than 50 days preceding the applicable Series A Distribution Payment Date;
provided that so long as the Series A Preferred Limited Partner Units are owned
by IAC Capital Trust, the General Partner shall establish record dates with
respect to the Series A Preferred Limited Partner Units that shall coincide with
the record dates established with respect to the __% Series A REIT Trust
Originated Preferred Securities of IAC Capital Trust (the "SERIES A PREFERRED
SECURITIES").

        (b)     Distributions on the Series A Preferred Limited Partner Units
shall accrue on a daily basis commencing on the date of original issuance of the
Series A Preferred Limited Partner Units, will accrue whether or not the
Partnership has earnings, whether or not there are funds legally available for
the payment of such distributions and whether or not such distributions are
declared. Accrued distributions will accumulate, to the extent not paid, as of
the Series A Distribution Payment Date on which they first become payable.
Accumulated and unpaid distributions will not bear interest.

        (c)     So long as any Series A Preferred Limited Partner Units are
outstanding, no distribution shall be paid or declared on or with respect to the
Common Limited Partner Units or the General Partner Units or any other series of
outstanding Preferred Limited Partner Units ranking junior as to the payment of
distributions to the Series A Preferred Limited Partner Units, nor shall any sum
or


                                       2

<PAGE>   3



sums be set aside for or applied to the purchase or redemption of the Series A
Preferred Limited Partner Units or any other series of outstanding Preferred
Limited Partner Units or the purchase, redemption or other acquisition for value
of any Common Limited Partner Units, General Partner Units or Preferred Limited
Partner Units of any series ranking junior to the Series A Preferred Limited
Partner Units as to the payment of distributions unless, in each case, full
cumulative distributions accumulated on all Series A Preferred Limited Partner
Units and all other series of outstanding Preferred Limited Partner Units
ranking on a parity with the Series A Preferred Limited Partner Units as to the
payment of distributions have been paid in full, provided that the foregoing
will not prohibit distributions payable solely in Common Limited Partner Units
or Preferred Limited Partner Units of a series ranking junior to the Series A
Preferred Limited Partner Units as to the payment of distributions, the exchange
of Common Limited Partner Units for REIT Shares in accordance with Section 8.6
of the Agreement, the repurchase of Common Limited Partner Units in connection
with the exercise by the holders thereof of the Cash Tender rights set forth in
Section 8.6 of the Agreement, the exchange of Common Limited Partner Units for
General Partner Units as provided in the Agreement or the repayment, return,
forfeiture and cancellation of Common Limited Partner Units issued in connection
with land acquisitions by the Partnership as and to the extent provided pursuant
to the purchase or other acquisition agreement relating to any such acquisition.
When distributions have not been paid in full upon the Series A Preferred
Limited Partner Units on the applicable Series A Distribution Payment Date (or a
sum sufficient for such full payment is not set apart therefor), all
distributions declared and paid on the Series A Preferred Limited Partner Units
and any other series of outstanding Preferred Limited Partner Units ranking on a
parity with the Series A Preferred Limited Partner Units as to the payment of
distributions shall be declared and paid so that the amount of distributions per
unit declared and paid on the Series A Preferred Limited Partner Units and such
other series of Preferred Limited Partner Units shall in all cases bear to each
other the same ratio that the respective distribution rights per unit of Series
A Preferred Limited Partner Units and such other series of Preferred Limited
Partner Units (which shall not include any accumulation in respect of unpaid
distributions for prior distribution periods if such other series of Preferred
Limited Partner Units do not have cumulative distribution rights) bear to each
other.

        (d)     The holders of outstanding Series A Preferred Limited Partner
Units will be entitled to receive, when, as and if declared by the Operating
Partnership acting through the General Partner out of funds legally available
therefor, such cash distributions, in addition to those described in Sections
3(a) through (c), that may be necessary to preserve the status of IAC Capital
Trust as a real estate investment trust for federal income tax purposes.


                                       3

        (e)     Holders of Series A Preferred Limited Partner Units shall not be
entitled to any distributions whether payable in cash, property or otherwise, in
excess of the full cumulative distributions as herein provided. Distributions
with respect to the dissolution, liquidation, winding-up or termination of the
Partnership shall be governed by Section 4 hereof.

        SECTION 4. Liquidation. Subject to the rights of the holders of any
other series of Preferred Limited Partner Units which the Partnership may issue
in the future which rank on a parity with the Series A Preferred Limited Partner
Units upon any voluntary or involuntary dissolution, liquidation, winding-up or
termination of the Partnership, the holders of the Series A Preferred Limited
Partner Units will be entitled to receive upon any such dissolution,
liquidation, winding-up or termination of the Partnership out of the assets of
the Partnership legally available for distribution, after payment or provision
for debts and other liabilities of the Partnership, an amount per Series A
Preferred Limited Partner Unit equal to the Stated Value, plus accrued and
unpaid distributions thereon to the date of payment (the "SERIES A LIQUIDATION
PREFERENCE AMOUNT") and no more. If, upon any such liquidation, dissolution,
winding-up or termination, there are insufficient assets to permit full payment
to the holders of Series A Preferred Limited Partner Units and any other series
of outstanding Preferred Limited Partner Units ranking on a parity upon
liquidation, dissolution, winding-up or termination of the Partnership with the
Series A Preferred Limited Partner Units, the holders of Series A Preferred
Limited Partner Units and such other series of Preferred Limited Partner Units
shall be paid ratably in proportion to the full distributable amount to which
holders of Series A Preferred Limited Partner Units and such other series of
Preferred Limited Partner Units are respectively entitled upon liquidation,
dissolution, winding-up or termination. The full preferential amount payable to
holders of the Series A Preferred Limited Partner Units and such other series of
outstanding Preferred Limited Partner Units upon any such liquidation,
dissolution, winding-up or termination will be paid in full before any
distribution or payment is made to the holders of General Partner Units, Common
Limited Partner Units and Preferred Limited Partner Units of any series ranking
junior to the Series A Preferred Limited Partner Units upon liquidation,
dissolution, winding-up or termination of the Partnership. The consolidation or
merger of the Partnership with or into any corporation, trust, partnership or
other entity (or of any corporation, trust, partnership or entity with or into
the Partnership) shall not be deemed to constitute a liquidation, dissolution,
winding-up or termination of the Partnership.

        SECTION 5. Stated Maturity and Redemption. (a) The Series A Preferred
Limited Partner Units shall mature and the Stated Value thereof shall be due and
payable on December 31, 2092 (the "STATED MATURITY DATE") whether or not the
term of the Partnership is extended. On the Stated Maturity Date the holders of



                                       4

<PAGE>   5



Series A Preferred Limited Partner Units shall be entitled to receive, upon
surrender of their certificates for the Series A Preferred Limited Partner
Units, out of funds legally available for distribution an amount in cash equal
to the Stated Value per Series A Preferred Limited Partner Unit, plus accrued
and unpaid distributions thereon to the date of payment (the "STATED MATURITY
PRICE") and no more.

        (b)     Except in the case of a Tax Event or Investment Company Act
Event (each as defined in Section 4(c) below), the Series A Preferred Limited
Partner Units may not be redeemed prior to ______________. On or after such date
the Partnership shall have the right to redeem the Series A Preferred Limited
Partner Units, in whole or in part, from time to time, upon notice as provided
in Section 4(d) below, at a redemption price equal to the Stated Value per
Series A Preferred Limited Partner Unit plus, subject to Section 5(g) hereof,
accumulated and unpaid distributions to the date of payment (the "SERIES A
REDEMPTION PRICE"), provided that the Partnership may not redeem fewer than all
the outstanding Series A Preferred Limited Partner Units unless all accumulated
and unpaid distributions have been paid on all Series A Preferred Limited
Partner Units for all quarterly distributions periods ending on or prior to the
date of redemption.

        (c)     If, at any time prior to _______________, a Tax Event or
Investment Company Event (each, a "SPECIAL EVENT") shall occur and be
continuing, the Partnership shall have the right to redeem the Series A
Preferred Limited Partner Units in whole but not in part at the Series A
Redemption Price, provided, however, that, if at the time there is available to
the Partnership or IAC Capital Trust the opportunity to eliminate, within a
90-day period, the Special Event by taking some ministerial action
(collectively, "MINISTERIAL ACTIONS"), such as filing a form or making an
election, or pursuing some other similar reasonable measure, which in the sole
judgment of the General Partner has or will cause no adverse effect on IAC
Capital Trust, the Partnership, Irvine Apartment Communities or the holders of
the Series A Preferred Securities and will involve no material cost, the
Partnership and IAC Capital Trust will pursue such measure in lieu of such
redemption, provided, further, that the Partnership shall have no right to
redeem the Series A Preferred Limited Partner Units while the Partnership or the
Regular Trustees (as defined in the Declaration of Trust) on behalf of IAC
Capital Trust are pursuing any such Ministerial Action. The Partnership shall
have the right, upon not less than 30 nor more than 60 days' notice, to redeem
the Series A Preferred Limited Partner Units in whole for cash at the Series A
Redemption Price as provided in Section 5(b) within 90 days following the
occurrence of such Special Event (subject to extension for the number of days
Ministerial Actions are pursued).


                                       5

<PAGE>   6



        "INVESTMENT COMPANY EVENT" means that the Partnership and the Regular
Trustees of IAC Capital Trust shall have received an opinion of nationally
recognized independent counsel experienced in practice under the Investment
Company Act of 1940, as amended (the "1940 ACT"), that as a result of the
occurrence of a change in law or regulation or a change in interpretation or
application of law or regulation by any legislative body, court, governmental
agency, or regulatory authority (a "CHANGE IN 1940 ACT LAW"), there is more than
an insubstantial risk that IAC Capital Trust is or will be considered an
"investment company" which is required to be registered under the 1940 Act,
which Change in 1940 Act Law becomes effective on or after ____________.

        "TAX EVENT" means that the Partnership and the Regular Trustees of IAC
Capital Trust shall have received an opinion of nationally recognized
independent tax counsel experienced in such matters that there is more than an
insubstantial risk that IAC Capital Trust does not qualify, or within 90 days of
the date of such opinion will no longer qualify, as a REIT under the Code and
Regulations for any reason whatsoever, provided that a Tax Event shall not
include the voluntary election by the Regular Trustees and/or the holders of the
Common Securities (as defined in the Declaration of Trust) of IAC Capital Trust
to terminate IAC Capital Trust's status as a real estate investment trust for
Federal income tax purposes.

        (d)     The Partnership will provide notice of any redemption of the
Series A Preferred Limited Partner Units to the holders of record thereof not
less than 30 nor more than 60 days prior to the date of redemption and in the
case of a mandatory repayment of the Series A Preferred Limited Partner Units on
the Stated Maturity Date will provide notice of such repayment not less than 30
nor more than 60 days prior to the Stated Maturity Date. Such notice shall be
provided by mailing notice of such redemption or mandatory repayment, first
class postage prepaid, to each holder of Series A Preferred Limited Partner
Units to be redeemed or to all holders in the event of mandatory repayment on
the Stated Maturity Date, at such holder's address as it appears on the transfer
records of the Partnership. Each such notice shall state, as appropriate, the
following:

                  (i)   the redemption date or the Stated Maturity Date;

                 (ii)   the Series A Redemption Price or the Stated Maturity
        Price;

                (iii)   the place or places where certificates for the Series A
        Preferred Limited Partner Units may be surrendered for payment;

                 (iv)   the number of the Series A Preferred Limited Partner
        Units to be redeemed from each holder;



                                       6

<PAGE>   7



                  (v)   that payment of the Series A Redemption Price or the
        Stated Maturity Price will be made upon presentation and surrender of
        such Series A Preferred Limited Partner Units; and

                 (vi)   that on or after the Stated Maturity Date or the
        redemption date distributions on the Series A Preferred Limited Partner
        Units to be redeemed or repaid will cease to accrue.

No failure to give or defect in a notice of redemption shall affect the validity
of the proceedings for redemption of any Series A Preferred Limited Partner
Units except as to the holder to which notice was defective or not given.

        (e)     If notice (which notice will be irrevocable) has been given as
provided above then, by 12:00 noon, New York City time, on the redemption date
or the Stated Maturity Date, as the case may be, the Partnership will deposit
irrevocably in trust for the benefit of the Series A Preferred Limited Partner
Units being redeemed or repaid funds sufficient to pay the applicable Series A
Redemption Price or Stated Maturity Price, as the case may be, and will give
irrevocable instructions and authority to pay such Series A Redemption Price or
Stated Maturity Price, as the case may be, to the holders of the Series A
Preferred Limited Partner Units entitled thereto. If notice shall have been
given as provided above and funds deposited as required, then upon the date of
such deposit, distributions will cease to accrue on the Series A Preferred
Limited Partner Units called for redemption or to be repaid, as the case may be,
such Series A Preferred Limited Partner Units will not longer be deemed to be
outstanding and all rights of holders of such Series A Preferred Limited Partner
Units so called for redemption or to be repaid, as the case may be, will cease,
except the right of the holders of such Series A Preferred Limited Partner Units
to receive the applicable Series A Redemption Price or Stated Maturity Price, as
the case may be, but without interest thereon. If the Stated Maturity Date or
any date fixed for redemption of Series A Preferred Limited Partner Units is not
a Business Day, then payment of the Series A Redemption Price or the Stated
Maturity Price, as the case may be, payable on such date will be made on the
next succeeding day that is a Business Day (and without any interest or other
payment in respect of any such delay) except that, if such Business Day falls in
the next calendar year, such payment will be made on the immediately preceding
Business Day, in each case with the same force and effect as if made on the
Stated Maturity Date or such date fixed for redemption. If payment of the Series
A Redemption Price or the Stated Maturity Price, as the case may be, in respect
of the Series A Preferred Limited Partner Units is improperly withheld or
refused and not paid by the Partnership, distributions on such Series A
Preferred Limited Partner Units will continue to accumulate from the original
redemption date or the Stated Maturity Date, as the case may be, to the date of
payment, in which case the actual payment date will



                                       7

<PAGE>   8



be used for purposes of calculating the applicable Series A Redemption Price or
the Stated Maturity Price, as the case may be. If fewer than all of the Series A
Preferred Limited Partner Units are to be redeemed, the General Partner shall
select Series A Preferred Limited Partner Units to be redeemed by lot or pro
rata (as nearly as practicable without creating fractional units) or in some
other equitable manner determined by the General Partner in its sole discretion.
Upon presentation of any certificate for Series A Preferred Limited Partner Unit
redeemed in part only, the Partnership shall execute and deliver, at the expense
of the Partnership, a new certificate equal to the unredeemed portion of the
Certificate so presented.

        (f)     In the event of any redemption of Series A Preferred Limited
Partner Units in part, the Partnership shall not be required to (i) issue,
register the transfer of or exchange any Series A Preferred Limited Partner
Units during a period beginning at the opening of business 15 days before any
selection for redemption of Series A Preferred Limited Partner Units and ending
at the close of business on the earliest date on which the relevant notice of
redemption is deemed to have been given to all holders of Series A Preferred
Limited Partner Units to be redeemed and (ii) register the transfer of or
exchange any Series A Preferred Limited Partner Units so selected for
redemption, in whole or in part, except the unredeemed portion of any Series A
Preferred Limited Partner Units being redeemed in part.

        (g)     The holders of Series A Preferred Limited Partner Units at the
close of business on a distribution record date will be entitled to receive the
distribution payable with respect to such Series A Preferred Limited Partners
Units on the corresponding Series A Distribution Payment Date notwithstanding
the redemption thereof between such distribution record date and the
corresponding Series A Distribution Payment Date or the Partnership's default in
the payment of the distribution due. Except as provided above, the Partnership
will make no payment or allowance for unpaid distributions, regardless of
whether in arrears, on Series A Preferred Limited Partner Units called for
redemption.

        (h)     The Series A Preferred Limited Partner Units do not have the
benefit of any sinking fund.

        (i)     Notwithstanding any other provision of this Section 5, the
Series A Redemption Price (other than the portion thereof consisting of
accumulated and unpaid distributions) shall be payable solely out of the sales
proceeds of capital stock of the General Partner, which will be contributed by
the General Partner to the Partnership as an additional capital contribution in
accordance with Section 4.5.E of the Agreement, or the sales proceeds of Limited
Partner Interests and from no other source, it being understood that this
Section 5(i) shall not be



                                       8

<PAGE>   9



applicable to payment of the Series A Liquidation Preference Amount or the
Stated Maturity Price.

        SECTION 6. Voting Rights. (a) Except as provided in Section 6(b) hereof
or as otherwise required by law and the Agreement, holders of Series A Preferred
Limited Partner Units shall not be entitled to vote on any matter. In any matter
in which the Series A Preferred Limited Partner Units are entitled to vote, each
Series A Preferred Limited Partner Unit shall be entitled to one vote.

        (b)     If any proposed amendment or modification of the Agreement would
materially and adversely affect the powers, special rights, preferences or
privileges of the Series A Preferred Limited Partner Units, then the holders of
outstanding Series A Preferred Limited Partner Units shall be entitled to vote
on such amendment or modification as a class, and such amendment or modification
shall not be effective except with the approval of holders of at least 66 2/3%
of the outstanding Series A Preferred Limited Partner Units, voting as a single
class; provided, however, that any such amendment or modification that would
authorize, create or issue any additional series of Preferred Limited Partner
Units ranking on a parity with or junior to the Series A Preferred Limited
Partner Units as to distributions or upon liquidation, dissolution, winding-up
or termination of the Partnership shall not be deemed to materially and
adversely effect such powers, special rights, preferences or privileges; and,
provided, further, that prior to ________, any amendment or modification to the
definition of Tax Event shall be deemed to materially and adversely effect such
powers, special rights, preferences and privileges.

        SECTION 7. Restrictions on Ownership and Transfer. The Series A
Preferred Limited Partner Units shall be owned and held solely by IAC Capital
Trust and, in addition to the restrictions on Transfer set forth in the
Agreement, the Series A Preferred Limited Partner Units may not be Transferred
in whole or in part, and no interest therein may be transferred, pledged,
assigned or otherwise disposed of, except to a successor of IAC Capital Trust
pursuant to and in accordance with the Declaration of Trust.

        SECTION 8. Ranking. The Series A Preferred Limited Partner Units rank
with respect to distributions and rights upon liquidation, dissolution,
winding-up or termination of the Partnership (i) senior to the General Partner
Units and the Common Limited Partner Units and (ii) on a parity with all other
series of Preferred Limited Partner Units issued by the Partnership unless the
terms of such other series specifically provide that such other series ranks
junior to the Series A Preferred Limited Partner Units.



                                       9

<PAGE>   10



        SECTION 9. Miscellaneous. (a) The Series A Preferred Limited Partner
Units are not convertible into or exchangeable for any other property or
securities of the Partnership or the General Partner.

        (b)     The form of certificate for the Series A Preferred Limited
Partner Units is attached hereto as Annex 1.

        (c)     In the event the Partnership purchases outstanding Series A
Preferred Securities by tender, in the open market or by private agreement in
accordance with the terms thereof, the Partnership shall promptly deliver or
cause to be delivered to the Property Trustee (as defined in the Declaration of
Trust) the Series A Preferred Securities so purchased and the Property Trustee
as the registered owner of the Series A Preferred Limited Partner Units shall
promptly deliver to the Partnership for cancellation an equal number of Series A
Preferred Limited Partner Units and the Series A Preferred Limited Partner Units
so cancelled shall no longer be deemed outstanding. In such event, the
Partnership shall deliver to the Property Trustee a new certificate for the
Series A Preferred Limited Partner Units which remain outstanding.

        IN WITNESS WHEREOF, the General Partner has executed this Designation
Instrument as of this ___ day of _______, 199_ and the Agreement is hereby
amended pursuant to Section 4.5.F thereof.

the Property Trustee shall be protected in withholding such notice if and so
long as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers, of the Property Trustee in good faith

                      (i) the duties and obligations of the Property Trustee
               shall be determined solely by the express provisions of this
               Declaration, and the Property Trustee shall not be liable except
               for the performance of such duties and obligations as are

                      (ii) in the absence of bad faith on the part of the
               Property Trustee, the Property Trustee may conclusively rely, as
               to the truth of the statements and the correctness of the
               opinions expressed therein, upon any certificates or opinions
               furnished to the Property Trustee; but in the case of any such
               certificates or opinions that by any provision hereof are
               specifically required to be furnished to the Property Trustee,
               the Property Trustee shall be under a duty to examine the same to
               determine whether or not they conform to the requirements of this

               error of judgment made in good faith by a Responsible Officer of
               the Property Trustee, unless it shall be proved that the Property
               Trustee was negligent in ascertaining the pertinent facts;

                      (iv) the Property Trustee shall not be liable with respect
               to any action taken or omitted to be taken by it in good faith in

               conferred upon the Property Trustee under this Declaration; and

                      (v) no provision of this Declaration shall require the
               Property Trustee to expend or risk its own funds or otherwise
               incur personal financial liability in the performance of any of
               its duties or in the exercise of any of its rights or powers, if
               it shall have reasonable ground for believing that the repayment
               of such funds or liability is not reasonably assured to it under
               the terms of this Declaration or adequate indemnity against such
               risk or liability is not reasonably assured to it.

               (d) Subject to the provisions of Section 2.10(a) and (c):

                      (i) whenever in the administration of this Declaration,
               the Property Trustee shall deem it desirable that a matter be
               proved or established prior to taking, suffering or omitting any
               action hereunder, the Property Trustee (unless other evidence is
               herein specifically

               of the Regular Trustees or by an authorized officer of IAC, Inc.,

                      (ii) The Property Trustee (A) may consult with counsel
               (which may be counsel to IAC, Inc. or any of its Affiliates and

               and with due care and the written advice or opinion of such
               counsel with respect to legal matters shall be full and complete
               authorization and protection in respect of any action taken,
               suffered or omitted by it hereunder in good faith and in reliance
               thereon and in accordance with such advice and opinion and (B)
               shall have the right at any time to seek instructions concerning
               the administration of this Declaration from any court of
               competent jurisdiction;

                      (iii) The Property Trustee may execute any of the trusts
               or powers hereunder or perform any duties hereunder either
               directly or by or through agents or attorneys and the Property
               Trustee shall not be responsible for any misconduct or negligence
               on the part of any agent or attorney appointed by it in good

               exercise any of the rights or powers vested in it by this
               Declaration at the request or direction of any Holders, unless

               reasonable security and indemnity against the costs, expenses
               (including attorneys' fees and expenses) and liabilities that
               might be incurred by it in complying with such request or
               direction; and

                      (v) Any action taken by the Property Trustee or its agents
               hereunder shall bind the Holders of the Securities and the
               signature of the Property Trustee or its agents alone shall be
               sufficient and effective to perform any such action; and no third
               party shall be required to inquire as to the authority of the
               Property Trustee to so act, or as to its compliance with any of
               the terms and provisions of this Declaration, both of which shall
               be conclusively evidenced by the Property Trustee's or its
               agent's taking such action.

               (a) Subject to Section 4.2(b), Trustees may be appointed, removed
or replaced without cause at any time:

                      (i)    until the issuance of any Securities, by written
               instrument executed by IAC, Inc.; and

                      (ii)   after the issuance of any Securities,

                             (A) other than with respect to a Special Regular
               Trustee, by vote of the Holders of a Majority in liquidation
               amount of the Common Securities voting as a class; and

                             (B) subject to the next two sentences of this
               clause (B), if an Appointment Event has occurred and is
               continuing with respect to one or more series of Preferred
               Securities, one (1) additional Regular Trustee for all such
               series, who shall have the same rights, powers and privileges
               under this Declaration as the Regular Trustees, (the "Special
               Regular Trustee"), may be appointed, who need not be an employee
               or officer of, or otherwise an Affiliate of IAC, Inc., by vote of
               the Holders of a Majority in aggregate liquidation amount of the
               series of Preferred Securities so affected (voting separately as
               a class with all other series of Preferred Securities upon which
               like voting have been conferred and are exercisable) and such
               Special Regular Trustee may only be removed (otherwise than by
               the operation of Section 4.2(c)), by vote of the Holders of a
               Majority in liquidation amount of each series of Preferred
               Securities upon which like voting rights have been conferred and

               have been conferred pursuant to the Certificate of Terms for such
               series notwithstanding that such right with respect to a series
               of Preferred Securities becomes exercisable subsequent to a
               Special Regular Trustee having been appointed by any other series
               of Preferred Securities. In such event, the Special

               Regular Trustee so appointed shall, without any further act or
               vote by the Holders of any series of Preferred Securities, be
               deemed to have been appointed to act in such capacity for all
               series of Preferred Securities upon which like voting rights have
               been conferred and are exercisable.

               (b)       (i)   The Trustee that acts as Property Trustee shall
                               not be removed in accordance with Section
                               4.2(a) until a Successor Property Trustee
                               possessing the qualifications to act as
                               Property Trustee under Section 4.1(c) has been

                               written instrument executed by such Successor
                               Property Trustee and delivered to the Regular
                               Trustees, IAC, Inc. and the Property Trustee
                               being removed; and

                         (ii)  the Trustee that acts as Delaware Trustee shall
                               not be removed in accordance with Section
                               4.2(a) until a successor Trustee possessing the
                               qualifications to act as Delaware Trustee under
                               Section 4.1(a)(3) (a "Successor Delaware
                               Trustee") has been appointed and has accepted
                               such appointment by written instrument executed

                               delivered to the Regular Trustees, IAC, Inc.
                               and the Delaware Trustee being removed.

               (c) A Trustee appointed to office shall hold office until his
successor shall have been appointed or until his death, removal or resignation;
provided that a Special Regular Trustee shall only hold office while an
Appointment Event is continuing and shall cease to hold office immediately after
the Appointment Event with respect to each series of Preferred Securities
pursuant to which the Special Regular Trustee was appointed and all other
Appointment Events cease to be continuing.

               (d) Any Trustee may resign from office (without need for prior or
subsequent accounting) by an instrument (a "Resignation Request") in writing
signed by the Trustee and delivered to IAC, Inc. and the Trust, which
resignation shall take effect upon such delivery or upon such later date as is
specified therein; provided, however, that:

                        (i) no such resignation of the Trustee that acts as the
               Property Trustee shall be effective until:

                               (A) a Successor Property Trustee possessing the
               qualifications to act as Property Trustee

               IAC, Inc. and the resigning Property Trustee; or

                               (B) if the Trust is excluded from the definition
               of an Investment Company solely by reason of Rule 3a-7, until the
               assets of the Trust have been completely liquidated and the
               proceeds thereof distributed to the Holders of the Securities in
               accordance with the priority and payment terms of each class or

                        (ii) no such resignation of the Trustee that acts as the
               Delaware Trustee shall be effective until a Successor Delaware
               Trustee has been appointed and has accepted such appointment by
               instrument executed by such Successor Delaware Trustee and
               delivered to the Trust, IAC, Inc. and the resigning Delaware
               Trustee; and

                        (iii) no such resignation of a Special Regular Trustee
               shall be effective until the 60th day following delivery of the
               Resignation Request to IAC, Inc. and the Trust or such later date
               specified in the Resignation Request during which period the
               Holders of the Preferred Securities of all series upon which the
               right to appoint a Special Regular Trustee upon the occurrence of
               an Appointment Event shall have been conferred and are then
               exercisable shall have the right to appoint a successor Special
               Regular Trustee as provided in this Article IV.

               (e) If no Successor Property Trustee or Successor Delaware

Section 4.2 within 60 days after delivery to IAC, Inc. and the Trust of a

SECTION 4.3  Vacancies Among Trustees.

               If a Trustee ceases to hold office for any reason and the number
of Trustees is not reduced pursuant to Section 4.1 or if the number of Trustees
is increased pursuant to Section 4.1, a vacancy shall occur. A resolution
certifying the existence of such vacancy by a majority of the Regular Trustees
shall be conclusive evidence of the existence of such vacancy. The vacancy shall
be filled with a Trustee appointed in accordance with the requirements of this
Article IV.

SECTION 4.4 Effect of Vacancies.

               The death, resignation, retirement, removal, bankruptcy,
dissolution, liquidation, incompetence or incapacity to perform the duties of a
Trustee, or any one of them, shall not operate to annul the Trust. Whenever a
vacancy in the number of Regular Trustees shall occur until such vacancy is
filled as provided in this Article IV, the Regular Trustees in office,
regardless of their number, shall have all the powers granted to the Regular
Trustees and shall discharge all the duties imposed upon the Regular Trustees by
this Declaration.

SECTION 4.5  Meetings.

               Meetings of the Regular Trustees shall be held from time to time
upon the call of any Trustee. Regular meetings of the Regular Trustees may be
held at a time and place fixed by resolution of the Regular Trustees. Notice of
any in-person meeting of the Regular Trustees shall be hand delivered or
otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 48 hours before such meeting. Notice of any
telephonic meeting of the Regular Trustees or any committee thereof shall be
hand delivered or otherwise delivered in writing (including by facsimile, with a
hard copy by overnight courier) not less than 24 hours before such meeting.
Notices shall contain a brief statement of the time, place and anticipated
purposes of the meeting. The presence (whether in person or by telephone) of a
Regular Trustee at a meeting shall constitute a waiver of notice of such meeting
except where a Regular Trustee attends a meeting for the express purpose of
objecting to the transaction of any activity on the ground that the meeting has
not been lawfully called or convened. Unless provided otherwise in this
Declaration, any action of the Regular Trustees may be taken at a meeting by
vote of a majority of the Regular Trustees present (whether in person or by
telephone) and eligible to vote with respect to such matter; provided that a
Quorum is present, or without a meeting by the unanimous written consent of the
Regular Trustees.

               on the Common Securities by a majority of the Regular Trustees in
               their sole and absolute discretion from funds legally available
               therefor;

                      (v) Unless otherwise provided in this Declaration, matters
               submitted for approval to Holders of Common Securities require a
               majority vote of the Common Securities present and voting
               thereon. The Holders of Common Securities have the exclusive
               right (subject to the terms of the Declaration) to appoint,
               remove or replace Trustees and to increase or decrease the number
               of Trustees, subject to the right of Holders of the Preferred
               Securities of a series to appoint (subject to Section 4.2(a)(B))
               a Special Regular Trustee upon the occurrence of an Appointment
               Event with respect to such series;

                      (vi) Subject to (1) the preferential rights of outstanding
               series of Preferred Securities, if any and (2) the preferential
               rights of outstanding series of Excess Preferred Securities, if
               any, in the event of any liquidation, dissolution or winding up
               of, the Trust, whether voluntary or involuntary, each Holder of
               Common Securities shall be entitled, after payment or provision
               for payment of the debts and other liabilities of the Trust and
               the amount to which the Holders of any series of Preferred
               Securities and Excess Preferred Securities hereafter classified
               or reclassified as having a preference on Distributions in the
               liquidation, dissolution or winding up of the Trust shall be
               entitled, to receive ratably with each other Holder of Common
               Securities all remaining assets of the Trust available for
               Distribution to the Holders of Common Securities; and

                      (vii) Holders of Common Securities have no subscription,
               redemption, conversion or preemptive rights;

               (d) A majority of Regular Trustees are authorized, subject to any
limitations prescribed by law and the provisions of this Article VI, to provide
for the issuance of the shares of Preferred Securities in series, by executing a
Certificate of Terms to establish from time to time the number of securities to
be included in each such series, and to fix the designations, powers,
preferences and rights of the securities of each such series and the
qualifications, limitations or restrictions thereof including, but not limited
to, the Ownership Limit applicable to such series of Preferred Securities;
provided, however, that the Regular Trustees shall not approve the issuance of a
series of Preferred Securities that would cause the Trust to be deemed an
Investment Company required to be registered under the Investment Company Act.
Except as required by law, as provided in Section 11.1(a) or as otherwise
provided in a Certificate of Terms with respect to a series of Preferred
Securities, Holders of Preferred Securities shall have no voting rights. Subject
to the provisions contained in Section 11.1(a), the Regular Trustees are
authorized to establish the terms of a series of Preferred Securities and to
cause the issuance thereof without the consent or vote of Holders of any class
or series of Securities. Upon issuance of a series of Preferred Securities, the
Certificate of Terms shall constitute an amendment to this Declaration and shall
become a part hereof whether or not attached hereto and an original executed
copy of such Certificate of Terms shall be delivered to the Property Trustee.

               (e) At such time as the Regular Trustees authorize a series of
Preferred Securities pursuant to Section 6.1(d), without any further or separate
action of the Regular Trustees, there shall be deemed to be authorized a series
of Excess Preferred Securities consisting of the number of securities included
in the series of Preferred Securities and having terms, rights, restrictions and
qualifications identical thereto, except to the extent that Article VIII
requires different terms. In such event, any







                                       33


<PAGE>   41



appropriate correlative modification in all defined terms shall be deemed to
have been made.

               (f) The Certificates shall be signed on behalf of the Trust by a
majority of the Regular Trustees. Such signatures may be the manual or facsimile
signatures of the present or any future Regular Trustee. Typographical and other
minor errors or defects in any such reproduction of any such signature shall not
affect the validity of any Certificate. In case any Regular Trustee of the Trust
who shall have signed any of the Certificates shall cease to be such Regular
Trustee before the Certificate so signed shall be delivered by the Trust, such
Certificate nevertheless may be delivered as though the person who signed such
Certificate had not ceased to be such Regular Trustee; and any Certificate may
be signed on behalf of the Trust by such persons as, at the actual date of the
execution of such Certificate, shall be the Regular Trustees of the Trust,
although at the date of the execution and delivery of the Declaration any such
person was not such a Regular Trustee. Certificates shall be printed,
lithographed or engraved or may be produced in any other manner as is reasonably
acceptable to the Regular Trustees, as evidenced by their execution thereof, and
may have such letters, numbers or other marks of identification or designation
and such legends or endorsements as the Regular Trustees may deem appropriate,
or as may be required to comply with any law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any stock exchange or
interdealer quotation system on which such Securities may be listed, or to
conform to usage. Pending the preparation of definitive Certificates, the
Regular Trustees on behalf of the Trust may execute temporary Certificates
(printed, lithographed or typewritten), in substantially the form of the
definitive Certificates in lieu of which they are issued, but with such
omissions, insertions and variations as may be appropriate for temporary
Certificates, all as may be determined by the Regular Trustees. Each temporary
Certificate shall be executed by the Regular Trustees on behalf of the Trust
upon the same conditions and in substantially the same manner, and with like
effect, as definitive Certificates. Without unnecessary delay, the Regular
Trustees on behalf of the Trust will execute and furnish definitive Certificates
and thereupon any or all temporary Certificates may be surrendered to the
transfer agent and registrar in exchange therefor (without charge to the
Holders). Each Certificate whether in temporary or definitive form shall be
countersigned by the manual or facsimile signature of an authorized signatory of
the Person acting as registrar and transfer agent with respect to such
Securities, which shall initially be the Property Trustee.

               (g) The consideration received by the Trust for the issuance of
the Capital Securities shall constitute a contribution to the capital of the
Trust and shall not constitute a loan to the Trust.

               (h) Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable.

               (i) Every Person, by virtue of having become a Holder or a
Preferred Security Indirect Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by this Declaration.

               (j) Upon issuance of the Common Securities as provided in this
Declaration, the Regular Trustees on behalf of the Trust shall return to IAC,
Inc. the $10 constituting initial trust assets as set forth in the Original
Declaration.

                              TERMINATION OF TRUST

SECTION 7.1 Termination of Trust.

               This Declaration and the Trust shall terminate and be of no
further force or effect when:

                      (i) (A) all of the Preferred Securities of all series
               shall have been repaid in accordance with the terms thereof or
               called for redemption and the amounts necessary for redemption
               thereof shall have been paid to the Holders thereof in accordance
               with the priority and payment terms of the Preferred Securities
               and (B) all of the Common Securities are no longer outstanding;
               or

                      (ii) upon the expiration of the term of the Trust as set
               forth in Section 2.15; or

                      (iii) upon the expiration of the term of IAC, L.P. on
               December 31, 2092, unless sooner dissolved.

and a certificate of cancellation is filed by the Trustees with the Secretary of
State of the State of Delaware. The Trustees shall so file such a certificate as
soon as practicable after the occurrence of an event referred to in this Section
7.1.

               The provisions of Sections 2.10 and 3.2 and Article IX shall
survive the termination of the Trust.

                              TRANSFER OF INTERESTS

SECTION 8.1  General.

               (a) Securities may only be transferred, in whole or in part, in
accordance with the terms and conditions set forth in this Declaration.

               (b) Subject to this Article VIII, Preferred Securities shall be
freely transferable.

SECTION 8.2 Restriction on Ownership and Transfers of Preferred Securities;
Exchange for Excess Preferred Securities.

               (a)  General.

                      (i) Except as provided in Section 8.2(f), no Person shall
               Beneficially Own shares of a series of Preferred Securities in
               excess of the Ownership Limit applicable to such series.

                      (ii) Except as provided in Section 8.2(f) (and subject to
               Section 8.4), any Transfer (whether or not such Transfer is the
               result of transactions entered into through the facilities of any
               stock exchange of interdealer quotation system) that, if
               effective, would result in any Person Beneficially Owning
               securities of a series of Preferred Securities in excess of the
               Ownership Limit applicable to such series shall be void ab initio
               as to the Transfer of such securities which would be otherwise
               Beneficially Owned by such Person in excess of the Ownership
               Limit applicable to such series, and the intended transferee
               shall acquire no rights in such securities.

<PAGE>   44




                      (iii) Except as provided in Section 8.2(f) (and subject to
               Section 8.4), any Transfer (whether or not such Transfer is the
               result of a transaction entered into through the facilities of
               any stock exchange or interdealer quotation system) that, if
               effective, would result in the Preferred Securities being
               Beneficially Owned by less than 100 Persons (determined without
               reference to any rules of attribution) shall be void ab initio as
               to the Transfer of such securities which would be otherwise
               Beneficially Owned by the transferee and the intended transferee
               shall acquire no rights in such securities.

                      (iv) A Transfer of Preferred Securities which is null and
               void under (A) Section 8.2(a)(ii) because it could, if effective,
               result in the ownership of a series of Preferred Securities in
               excess of the Ownership Limit applicable to such Series or (B)
               Section 8.2(a)(iii) because it could, if effective, result in the
               Preferred Securities being beneficially owned by fewer than 100
               Persons, shall not adversely affect the validity of the Transfer
               of any other Preferred Securities in the same or any other
               related transaction.

               (b) Remedies for Breach.

                      If a majority of the Regular Trustees shall at any time
determine in good faith that a Transfer or other event has taken place in
violation of Section 8.2(a) (whether or not such violation is intended), or that
a Person intends to acquire or has attempted to acquire Beneficial Ownership of
any Preferred Securities in violation of Section 8.2(a), the majority of the
Regular Trustees shall be empowered to take any action as they deem advisable to
refuse to give effect to or to prevent such Transfer or other event, including,
but not limited to, refusing to give effect to such Transfer or other event on
the books of the Trust, demanding the repayment of any Distributions received in
respect of such Preferred Securities acquired in violation of Section 8.2(a) or
instituting proceedings to enjoin such Transfer or rescind such Transfer or
attempted Transfer; provided, however, that any Transfers or attempted Transfers
(or in the case of events other than a Transfer, Beneficial Ownership) in
violation of Section 8.2(a), regardless of any action (or non-action) by the
Regular Trustees, (i) shall be void ab initio and (ii) shall automatically
result in the exchange described in Section 8.2(c).

               (c) Exchange for Excess Stock. If, notwithstanding the other
provisions contained in this Article VIII, at any time there is a purported
Transfer (whether or not such Transfer is the result of a transaction entered
into through the facilities of any stock exchange or interdealer quotation
system) or other change in the capital structure of the Trust or other event
such that any Person would Beneficially Own securities of a series of Preferred
Securities in excess of the Ownership Limit applicable to such series, then,
except as otherwise provided in Section 8.2(f), such Preferred Securities in
excess of the Ownership Limit applicable to such series (rounded up to the
nearest whole security) shall be automatically exchanged for an equal number of
securities of Excess Preferred Securities having the terms set forth in Section
8.3. Such exchange shall be effective as of the close of business on the
business day prior to the date of the Transfer or change in capital structure or







                                       37

other event.

               (d) Notice of Restricted Transfer. Any Person who acquires or
attempts to acquire Preferred Securities in violation of Section 8.2(a), or any
Person who is a transferee who would cause the issuance of Excess Shares under
Section 8.2(c), shall immediately give written notice to the Trust of such event
and shall provide to the Regular Trustees such other information as the Regular
Trustees may request in order to determine the effect, if any, of such Transfer
or attempted Transfer or other event on the Trust's status as a REIT. Failure to
give such notice shall not limit the rights and remedies of the Regular Trustees
provided herein in any way.

               (e) Owners Required to Provide Information. From and after the
date of this Declaration:

                      (i) Every record and Beneficial Owner of more than 5% (or
               such other percentage between 1/2 of 1% and 5%, as determined by
               a majority of the Regular Trustees) of any series of Preferred
               Securities outstanding shall, within 30 days after January 1 of
               each year, give written notice to the Trust stating the name and
               address of such record or Beneficial Owner, the number of
               securities of any series of Preferred Securities Beneficially
               Owned, and a full description of how such securities are held.
               Each such record or Beneficial Owner of Preferred Securities
               shall, upon demand by the Trust, disclose to the Trust in writing
               such additional information with respect to the Beneficial
               Ownership of the Preferred Securities as a majority of the
               Regular Trustees, in their sole discretion, deem appropriate or
               necessary to (i) comply with the provisions of the Code regarding
               the qualification of the Trust as a REIT under the Code, and (ii)
               ensure compliance with the applicable Ownership Limit. Each
               Holder of record, including without limitation any Person
               (including a Clearing Agency) who holds Preferred Securities on
               behalf of a Beneficial Owner, shall take all reasonable steps to
               obtain the written notice described in this Section 8.2(e)(i)
               from the Beneficial Owner.

                      (ii) Any Person who is a Beneficial Owner of securities of
               any series of Preferred Securities and any Person (including the
               Holder of record) who is holding Preferred Securities for a
               Beneficial Owner, and any proposed transferee of Preferred
               Securities, shall provide such information as a majority of the
               Regular Trustees, in their sole discretion, may request in order
               to determine the Trust's status or to comply with the
               requirements of any taxing authority or other governmental
               agency, to determine any such compliance or to ensure compliance
               with the applicable Ownership Limit, and shall provide a
               statement or affidavit to the Trust setting forth the number of
               securities of any series of Preferred Securities already
               Beneficially Owned by such Holder or proposed transferee and any
               related persons specified, which statement or affidavit shall be
               in the form prescribed by a majority of the Regular Trustees for
               that purpose.

               (f)  Exceptions.

                      (i) A majority of the Regular Trustees, upon receipt of a
               ruling from the Internal Revenue Service or an opinion of
               nationally recognized tax counsel experienced in such matters,
               may waive the application, in whole or in part, of the applicable
               Ownership Limit to a Person, if such Person is not an individual
               for purposes of section 542(a) of the Code and is a corporation,
               partnership, estate or trust, provided, however, in no event may
               any such exception cause such Person's ownership, direct or
               indirect, to exceed 9.8% of the value of the Outstanding
               Preferred Securities and Excess Preferred Securities, as such
               value is determined by a majority of the Regular Trustees in
               their sole discretion. In connection with any such exemption, a
               majority of the Regular Trustees may require such representations
               and undertakings from such Person and may impose such other
               conditions as they deem necessary, in their sole discretion, to
               determine the effect, if any, of the proposed Transfer on the
               Trust's status as a REIT.

                      (ii) For a period of 270 days following the purchase of
               any series of Preferred Securities by an underwriter that (i) is
               a corporation, limited liability company, partnership or other
               entity and (ii) participates in an offering of such series of
               Preferred Securities, such underwriter shall not be subject to
               the Ownership Limit applicable to such series with respect to the
               Preferred Securities purchased by it as a part of or in
               connection with such offering and with respect to any Preferred
               Securities purchased in connection with market making activities.

               (g)  Legend.

                      Each Preferred Securities Certificate shall bear the
        following legend or such other legend as the majority of the Regular
        Trustees may establish in accordance with Section 6.1(d) at the time
        such series of Preferred Securities is established:

                      "The Preferred Securities represented by this certificate
               are subject to restrictions on transfer. No person may
               Beneficially Own securities of this series of Preferred
               Securities in excess of the Ownership Limit applicable to this
               series of Preferred Securities, with certain further restrictions
               and exceptions set forth in the Amended and Restated Declaration
               of Trust of IAC Capital Trust dated as of _____, 199_, as amended
               from time to time ("Declaration"). Any person who attempts to
               Beneficially Own securities of this series of Preferred
               Securities in excess of the applicable limitation must
               immediately notify the Trust. All capitalized terms in this
               legend have the meanings ascribed to such terms in the

               Declaration, as the same may be amended from time to time, a copy
               of which, including the restrictions on transfer, will be sent
               without charge to each Holder of Preferred Securities of this
               series who requests such a copy. If the restrictions on transfer
               are violated, the transfer will be void in accordance with the
               Declaration and the Preferred Securities represented hereby will
               be automatically exchanged for Excess Preferred Securities which
               will be held in trust in accordance with the Declaration."

SECTION 8.3  Excess Preferred Securities.

               The following is a description of the preferences, conversion and
other rights, voting powers, restrictions, limitations as to Distributions,
qualifications and terms and conditions of redemption of the Excess Preferred
Stock of the Trust:

               (a)  Ownership in Trust.

                     Upon any purported Transfer, change in the capital
structure of the Trust or purported change in Beneficial Ownership that results
in Excess Preferred Securities pursuant to Section 8.2(c), such Excess Preferred
Securities shall be deemed to have been transferred to a Person as trustee of a
Charitable Trust for the exclusive benefit of one or more organizations
described in sections 170(b), 170(c), or 501(c)(3) of the Code (the "Charitable
Beneficiary" or "Charitable Beneficiaries"), as shall be designated by a
majority of the Regular Trustees in writing, such trustee to be a person who is
unaffiliated with (i) the Trust, (ii) the Purported Beneficial Transferee; and
(iii) the Purported Record Transferee. At all times at least one Charitable
Beneficiary shall be designated by the Regular Trustees. Where a Transfer or
other event results in an automatic exchange of securities of more than one
series for Excess Preferred Securities, then separate Charitable Trusts shall be
deemed to have been established for the Excess Preferred Securities attributable
to the securities of each such series. Securities of Excess Preferred Securities
held in Charitable Trust for the exclusive benefit of the Charitable Beneficiary
shall be issued and outstanding securities of the Trust. The trustee of the
Charitable Trust will be deemed to own the Excess Preferred Securities held in
Charitable Trust for the exclusive benefit of the Charitable Beneficiary on the
day prior to the date of the violative transfer. The Purported Beneficial
Transferee shall have no rights in the shares of Excess Preferred Securities
except the right to receive a price for its interest in the Preferred Securities
which were exchanged for Excess Preferred Securities upon the terms specified in
Section 8.3(e).

               (b)  Distribution Rights.

                      Excess Preferred Securities shall be entitled to
Distributions as if such Excess Preferred Securities were Preferred Securities
of the series or class in existence immediately prior to the exchange of such
Excess Preferred Securities, provided that the Distributions shall be paid to
the Charitable Trustee to be held in Charitable Trust for the exclusive benefit
of the Charitable Beneficiary. Any Distribution paid prior to the discovery

by the Trust that the Preferred Securities have been exchanged for Excess
Preferred Securities shall be repaid to the Trust upon demand or, at the Trust's
sole election, shall be offset against any future Distributions payable to the
Purported Record Transferee. Any Distributions so disgorged shall be paid over
to the Charitable Trustee for the exclusive benefit of the Charitable
Beneficiary.

               (c)  Rights Upon Liquidation.

                     Subject to the preferential rights of Preferred
Securities, if any, each Purported Beneficial Transferee of Excess Preferred
Securities shall be entitled to receive that portion of the assets of the Trust
which a Holder of Preferred Securities that was exchanged for such Excess
Preferred Securities would have been entitled to receive on liquidation had such
Preferred Securities remained outstanding provided that no Purported Beneficial
Transferee shall be entitled to receive any amounts in excess of the price per
security such Purported Beneficial Transferee paid for the Preferred Securities
in any purported Transfer that resulted in the Excess Preferred Securities or,
if the Purported Beneficial Transferee did not give value for such Excess
Preferred Securities (through a gift, devise or other transaction) in any
purported Transfer, a price per security equal to the Market Price on the date
of any purported Transfer that resulted in the Excess Preferred Securities, less
the amount of any Distributions received by the Purported Record Transferee and
not repaid or offset against future Distributions pursuant to Section 8.3(b),
with any remainder of such Transferee's ratable portion of the Trust's assets
subject to ratable allocation among the Holders of Securities ranking junior to
such Excess Preferred Securities as to the payment of Distributions and upon
liquidation dissolution, winding-up or termination of the Trust as an asset of
the Trust.

               (d)  Voting Rights.

                      Subject to Delaware law, effective as of the date that 
Preferred Securities are exchanged for Excess Preferred Securities pursuant to
Section 8.2(c), the Holders of Preferred Securities that have been exchanged for
Excess Preferred Securities shall not be entitled to vote such Preferred
Securities on any matter, and, if such Preferred Securities have voting rights,
all votes cast with respect to securities of Excess Preferred Securities into
which such Preferred Securities have been exchanged shall be voted in accordance
with the direction of the Charitable Trustee of the Charitable Trust acting for
the benefit of the Charitable Beneficiary. The Charitable Trustee shall vote the
securities of Excess Preferred Securities for the exclusive benefit of the
Charitable Beneficiary.

               (e) Restrictions on Transfer.

                      (i) Excess Preferred Securities shall not be transferable.
               The Purported Record Transferee may freely designate a Person as
               beneficiary of an interest in the Charitable Trust (representing
               the number of shares of Excess Preferred Securities held by the
               Charitable Trust attributable to a purported Transfer that
               resulted in the Excess Preferred Securities), if (A) the shares
               of










                                       41


<PAGE>   49



               Excess Preferred Securities held in the Charitable Trust would
               not be Excess Preferred Securities in the hands of such Person
               and (B) the Purported Beneficial Transferee does not receive a
               price from such Person that reflects a price per security for
               such Excess Preferred Securities that exceeds the lesser of (1)
               the price per security such Purported Beneficial Transferee paid
               for the Preferred Securities in the purported Transfer that
               resulted in the Excess Preferred Securities, or if the Purported
               Beneficial Transferee did not give value for such Excess
               Preferred Securities (through a gift, devise or other
               transaction), a price per security equal to the Market Price on
               the date of the purported Transfer that resulted in the Excess
               Preferred Securities and (2) the price per security of the
               Preferred Securities in the transfer described in the following
               sentence. Upon the transfer of an interest in the Charitable
               Trust, the corresponding Excess Preferred Securities in the
               Charitable Trust shall be automatically exchanged for an equal
               number of securities of Preferred Securities of the applicable
               series of Preferred Securities and such Preferred Securities
               shall be transferred of record to the transferee of the interest
               in the Charitable Trust if such Preferred Securities would not be
               Excess Preferred Securities in the hands of such transferee. In
               the event of such transfer, the beneficial interest of the
               Charitable Beneficiary in the Excess Preferred Securities will
               terminate. Prior to any transfer of any interest in the
               Charitable Trust, the Purported Record Transferee must give not
               less than five business days prior written notice to the Trust of
               the intended transfer and the Trust must have waived in writing
               its purchase rights under Section 8.3(f).

                      (ii) Notwithstanding the foregoing, if a Purported
               Beneficial Transferee receives a price for its interest in the
               shares of Preferred Securities that were exchanged for Excess
               Preferred Securities that exceeds the amounts allowable under
               Section 8.3(e)(i), such Purported Beneficial Transferee shall,
               prior to the exchange of the Excess Preferred Securities for
               Preferred Securities, pay, or cause the Person designated
               pursuant to Section 8.3(e)(i) to pay, such excess to the
               Charitable Trustee to be held for the exclusive benefit of the
               Charitable Beneficiary.

                      (iii) If any of the transfer restrictions set forth in
               this Section 8.3(e) or any application thereof is determined in a
               final and nonappealable judgment to be void, invalid or
               unenforceable by any court having jurisdiction over the issue,
               the Purported Record Transferee may be deemed, at the option of a
               majority of the Regular Trustees, to have acted as the agent of
               the Trust in acquiring the excess Preferred Securities as to
               which such restrictions would, by their terms, apply, and to hold
               such Excess Preferred Securities on behalf of the Trust.

               (f)  Purchase Right in Excess Preferred Securities.

                    Excess Preferred Securities shall be deemed to have been
offered for sale





                                       42


<PAGE>   50



to the Trust, or its designee (as specified by a majority of the Regular
Trustees), at a price per security equal to the lesser of (i) the price per
security in the transaction that created such Excess Preferred Securities (or,
in the case of a devise or gift, the Market Price at the time of such devise or
gift) and (ii) the Market Price on the date the Trust, or its designee, accepts
such offer. The Trust (or its designee) shall have the right to accept such
offer for a period of ninety days after the later of (i) the date of the
Transfer which resulted in such Excess Preferred Securities and (ii) the date a
majority of the Regular Trustees determines in good faith that a Transfer
resulting in Excess Preferred Securities has occurred. A majority of the Regular
Trustees may appoint a special trustee of the Charitable Trust established under
Section 8.3(a) for the purpose of consummating the purchase of Excess Preferred
Securities by the Trust (or its designee).

SECTION 8.4  Settlement.

               Nothing in this Article VIII shall be interpreted to preclude the
settlement of any transaction entered into through facilities of any stock
exchange or interdealer quotation system.

SECTION 8.5  Remedies Not Limited.

               Nothing contained in this Article VIII shall limit the authority
of the Regular Trustees to take such other action as they deem necessary or
advisable (subject to the provisions of Section 8.4), (i) to protect the Trust
and the interests of the Holders of its Capital Securities in the preservation
of the Trust's status as a REIT, and (ii) to ensure compliance with the
applicable Ownership Limit

SECTION 8.6  Ambiguity.

               In the case of an ambiguity in the application of any of the
provisions of this Article VIII, including with respect to any of the related
definitions set forth in Article I, a majority of the Regular Trustees shall
have the power to determine the application of the provisions of this Article
VIII with respect to any situation based on their reasonable belief
understanding or knowledge of the circumstances.

SECTION 8.7  Severability.

               If any provision of this Article VIII or any application of any
such provision is determined in a final and unappealable judgment to be void,
invalid or unenforceable by any Federal or state court having jurisdiction over
the issues, the validity and enforceability of the remaining provisions shall
not be affected and other applications of such provision shall be affected only
to the extent necessary to comply with the determination of such court.

SECTION 8.8  Regular Trustees Discretion.

               Anything in this Article VIII to the contrary notwithstanding,
  a majority of the








                                       43


<PAGE>   51



Regular Trustees shall be entitled to take or omit to take such actions as they
in their discretion shall determine to be advisable in order that the Trust
maintain its status as and continue to qualify as a REIT, including, but not
limited to, reducing the applicable Ownership Limit, in the event of a change in
law.

SECTION 8.9 Transfer of Certificates.

               The Regular Trustees shall provide for the registration of
Certificates and of transfers of Certificates, which will be effected without
charge but only upon payment (with such indemnity as the Regular Trustees may
require) in respect of any tax or other government charges which may be imposed
in relation to it. Upon surrender for registration of transfer of any
Certificate, the Regular Trustees shall cause one or more new Certificates to be
issued in the name of the designated transferee or transferees. Every
Certificate surrendered for registration of transfer shall be accompanied by a
written instrument of transfer in form satisfactory to the Regular Trustees duly
executed by the Holder or such Holder's attorney duly authorized in writing.
Each Certificate surrendered for registration of transfer shall be canceled by
the Regular Trustees. A transferee of a Certificate shall be entitled to the
rights and subject to the obligations of a Holder hereunder upon the receipt by
such transferee of a Certificate. By acceptance of a Certificate, each
transferee shall be deemed to have agreed to be bound by this Declaration.

SECTION 8.10  Deemed Security Holders.

               The Trustees may treat the Person in whose name any Certificate
shall be registered on the books and records of the Trust as the sole Holder of
such Certificate and of the Securities represented by such Certificate for
purposes of receiving Distributions and payments on redemption and liquidation
of the Trust and for all other purposes whatsoever and, accordingly, shall not
be bound to recognize any equitable or other claim to or interest in such
Certificate or in the Securities represented by such Certificate on the part of
any Person, whether or not the Trustees shall have actual or other notice
thereof.

SECTION 8.11  Book Entry Interests.

               Unless otherwise specified in the terms of any series of the
Preferred Securities, Preferred Securities Certificates will be issued in the
form of one or more, fully registered, global Preferred Security Certificates
(each a "Global Certificate"), to be delivered to DTC, the initial Clearing
Agency, by, or on behalf of, the Trust. Such Global Certificates shall initially
be registered on the books and records of the Trust in the name of Cede & Co.,
the nominee of DTC, and no Preferred Security Indirect Owner will receive a
definitive Preferred Security Certificate representing such Preferred Security
Indirect Owner's interests in such Global Certificates, except as provided in
Section 8.14. Unless and until definitive, fully registered Preferred Security
Certificates (the "Definitive Preferred Security Certificates") with respect to
a series of Preferred Securities have been







                                       44


<PAGE>   52



issued to the Preferred Security Indirect Owners pursuant to Section 8.14:

                      (i)    the provisions of this Section 8.7 shall be in
               full force and effect;

                      (ii) the Trust and the Trustees shall be entitled to deal
               with the Clearing Agency for all purposes of this Declaration
               (including the payment of Distributions on the Global
               Certificates and payments or redemption or liquidation of the
               Trust and receiving approvals, votes or consents hereunder) as
               the Holder of such series of such Preferred Securities and the
               sole Holder of the Global Certificates and, except as set forth
               herein or in Rule 3a-7 with respect to the Property Trustee,
               shall have no obligation to the Preferred Security Indirect
               Owners;

                      (iii) to the extent that the provisions of this Section
               8.11 conflict with any other provisions of this Declaration, the
               provisions of this Section 8.11 shall control; provided that this
               clause (iii) shall in no event limit or restrict the provisions
               of Sections 8.2 though 8.8 hereof which shall in all events be
               controlling;

                      (iv) the rights of the Preferred Security Indirect Owners
               shall be exercised only through the Clearing Agency and shall be
               limited to those established by law and agreements between such
               Preferred Security Indirect Owners and the Clearing Agency and/or
               the Clearing Agency Participants. DTC will make book entry
               transfers among the Clearing Agency Participants and receive and
               transmit payments of Distributions on, and payments or redemption
               of, the Global Certificates and in connection with the
               liquidation of the Trust, to such Clearing Agency Participants.

SECTION 8.12 Notices to Holders of Certificates.

               Whenever a notice or other communication to the Holders of
Preferred Securities is required to be given under this Declaration, unless and
until Definitive Preferred Security Certificates with respect to series of
Preferred Securities shall have been issued pursuant to Section 8.14, the
relevant Trustees shall give all such notices and communications, specified
herein to be given to Preferred Securities Holders of such series of Preferred
Securities, to the Clearing Agency and, with respect to any Preferred Security
Certificate registered in the name of a Clearing Agency or the nominee of a
Clearing Agency, the Trustees shall, except as set forth herein or in Rule 3a-7
with respect to the Property Trustee, have no notice obligations to the
Preferred Security Indirect Owners of such series of Preferred Securities.

SECTION 8.13  Appointment of Successor Clearing Agency.

               If any Clearing Agency elects to discontinue its services as
securities depositary with respect to any series of the Preferred Securities,
the Regular Trustees may, in their sole discretion, appoint a successor Clearing
Agency with respect to such series of Preferred Securities.

SECTION 8.14  Definitive Preferred Securities Certificates.

               If (i) a Clearing Agency elects to discontinue its services as
securities depositary with respect to a particular series of Preferred
Securities and a successor Clearing Agency is not appointed within 90 days after
such discontinuance pursuant to Section 8.13 or (ii) the Regular Trustees elect
after consultation with IAC, Inc. to terminate the book entry system through the
Clearing Agency with respect to the Preferred Securities of a series, then (x)
Definitive Preferred Security Certificates shall be prepared by the Regular
Trustees on behalf of the Trust with respect to such series of Preferred
Securities and (y) upon surrender of the Global Certificates by the Clearing
Agency, accompanied by registration instructions, the Regular Trustees shall
cause definitive Preferred Security Certificates to be delivered to Preferred
Security Indirect Owners of such series in accordance with the instructions of
the Clearing Agency. Neither the Trustees nor the Trust shall be liable for any
delay in delivery of such instructions and each of them may conclusively rely on
and shall be protected in relying on, such instructions.

SECTION 8.15  Mutilated, Destroyed, Lost or Stolen Certificates.

               If (a) any mutilated Certificates should be surrendered to the
Regular Trustees, or if the Regular Trustees shall receive evidence to their
satisfaction of the destruction, loss or theft of any Certificate; and (b) there
shall be delivered to the Regular Trustees such security or indemnity as may be
required by them to keep each of them and the Trust harmless, then in the
absence of notice that such Certificate shall have been acquired by a bona fide
purchaser, a majority of Regular Trustees on behalf of the Trust shall execute
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Certificate, a new Certificate of like denomination. In connection
with the issuance of any new Certificate under this Section 8.15, the Regular
Trustees may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith. Any duplicate
Certificate issued pursuant to this Section shall constitute conclusive evidence
of an ownership interest in the relevant Securities, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

SECTION 9.1  Exculpation.

               (a) No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust or any Covered Person for any
loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Declaration or by law,
except that an Indemnified Person shall be liable for any such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence (or, in
the case of the Property Trustee, negligence) or willful misconduct with respect
to such acts or omissions.

               (b) An Indemnified Person shall be fully protected in relying in
good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses or any other facts pertinent to the existence and amount of assets from
which Distributions, redemption payments and payments on liquidation,

be paid.

               (c) Pursuant to Section 3803(a) of the Business Trust Act, the

same limitation of liability that is extended to stockholders of private
corporations for profit organized under the General Corporation Law of the State
of Delaware.

SECTION 9.2  Indemnification.

               (a) To the fullest extent permitted by applicable law, IAC, L.P.

               (b) To the fullest extent permitted by applicable law, expenses
(including legal fees) incurred by an Indemnified Person in defending any claim,

                                   ACCOUNTING

SECTION 10.1 Fiscal Year.

               The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

SECTION 10.2  Certain Accounting Matters.

               (a) At all times during the existence of the Trust, the Regular
Trustees shall keep, or cause to be kept, full books of account, records and
supporting documents, which shall reflect in reasonable detail, each transaction
of the Trust. The books of account shall be maintained on the accrual basis
method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual basis method
of accounting for United States federal income tax purposes. The books and
records of the Trust, together with a copy of this Declaration and a certified
copy of the Certificate of Trust, or any amendment thereto, shall at all times
be maintained at the principal office of the Trust and shall be open for
inspection for any examination by any Holder or its duly authorized
representative for any purpose reasonably related to its interest in the Trust
during normal business hours.

               (b) The Regular Trustees shall, as soon as available after the
end of each Fiscal Year of the Trust, cause to be prepared and mailed to each
Holder of Securities unaudited financial statements of the Trust for such Fiscal
Year, prepared in accordance with generally accepted accounting principles;
provided that if the Trust is required to comply with the periodic reporting
requirements of Sections 13(a) or 15(d) of the Exchange Act, such financial
statements for such Fiscal Year shall be examined and reported on by a firm of
independent certified public accountants selected by the Regular Trustees (which
firm may be the firm used by IAC, Inc.).

               (c) The Regular Trustees shall cause to be prepared and mailed to
each Holder of Securities, an annual United States federal income tax
information statement, on







                                       48


<PAGE>   56



such form as is required by the Code, containing such information with regard to
the Securities held by each Holder as is required by the Code and the Treasury
Regulations. Notwithstanding any right under the Code to deliver any such
statement at a later date, the Regular Trustees shall endeavor to deliver all
such statements within 30 days after the end of each Fiscal Year of the Trust.

               (d) The Regular Trustees shall cause to be prepared and filed
with the appropriate taxing authority, an annual United States federal income
tax return, on such form as is required by the Code, and any other annual income
tax returns required to be filed by the Regular Trustees on behalf of the Trust
with any state or local taxing authority, such returns to be filed as soon as
practicable after the end of each Fiscal Year of the Trust.

SECTION 10.3  Banking.

               The Trust shall maintain one or more bank accounts in the name
and for the sole benefit of the Trust; provided, however, that all payments of
funds in respect of the Preferred L.P. Units held by the Property Trustee shall
be made directly to the Property Account and no other funds from the Trust shall
be deposited in the Property Account. The sole signatories for such accounts
shall be designated by the Regular Trustees; provided, however, that the
Property Trustee shall designate the sole signatories for the Property Account.

SECTION 10.4  Withholding.

               The Trust and the Trustees shall comply with all withholding
requirements under United States federal, state and local law. The Trust shall
request, and the Holders shall provide to the Trust, such forms or certificates
as are necessary to establish an exemption from withholding with respect to each
Holder, and any representations and forms as shall reasonably be requested by
the Trust to assist it in determining the extent of, and in fulfilling, its
withholding obligations. The Trust shall file required forms with applicable
jurisdictions and, unless an exemption from withholding is properly established
by a Holder, shall remit amounts withheld with respect to the Holder to
applicable jurisdictions. To the extent that the Trust is required to withhold
and pay over any amounts to any authority with respect to Distributions or
allocations to any Holder, such amount withheld shall be deemed to be a
Distribution to the Holder. In the event of any







                                       49


<PAGE>   57



claimed overwithholding, Holders shall be limited to an action against the
applicable jurisdiction. If the amount to be withheld was not withheld from a
Distribution, the Trust may reduce subsequent Distributions by the amount of
such withholding.

                             AMENDMENTS AND MEETINGS

SECTION 11.1  Amendments.

               (a) Except as otherwise provided in this Declaration or by any
applicable terms of the Securities or as required by law or the rules of any
stock exchange or interdealer quotation system on which the Preferred Securities
of a series are listed, this Declaration may be amended by, and only by, a
written instrument executed by a majority of the Regular Trustees; provided,
however, that (i) no amendment or modification to this Declaration shall be made
unless the Regular Trustees shall have obtained (A) either a ruling from the
Internal Revenue Service or a written unqualified opinion of nationally
recognized independent tax counsel experienced in such matters to the effect
that the Trust will continue to be treated as a REIT for purposes of United
States federal income taxation and (B) a written unqualified opinion of
nationally recognized independent counsel experienced in such matters to the
effect that such amendment or modification will not cause the Trust to be an
Investment Company which is required to be registered under the Investment
Company Act; provided no such ruling or opinions shall be required in connection
with the issuance of a series of Preferred Securities or the establishment of
the terms thereof, (ii) so long as any Preferred Securities remain outstanding

               having a right to vote thereat not less than 7 days nor more than
               60 days prior to the date of such meeting. Whenever a vote,
               consent or approval of the Holders of a class or series of
               Securities is permitted or required under this Declaration,
               pursuant to a Certificate of Terms of a series of Preferred
               Securities, or the rules of any stock exchange or interdealer

               Holders of such class or series of Securities owning not less
               than the minimum aggregate liquidation amount of such class or
               series of Securities that would be necessary to authorize or take
               such action at a meeting at which all Holders of such class or
               series of Securities having a right to vote thereon were present
               and voting. Prompt notice of the taking of action without a
               meeting shall be given to the Holders of such class or series of
               Securities entitled to vote who have not consented in writing.
               The Regular Trustees may specify that any written ballot
               submitted to the Holders of Securities for the purpose of taking
               any action without a meeting shall be returned to the Trust
               within the time specified by the Regular Trustees.

               Security is entitled to participate, including waiving notice of
               any meeting, or voting or participating at a meeting. No proxy
               shall be valid after the expiration of 11 months from the date
               thereof unless otherwise provided in the proxy. Every proxy shall
               be revocable at the pleasure of the Holder of the Security
               executing it. Except as otherwise provided in this Declaration,
               all matters relating to the giving, voting or validity of proxies
               shall be governed by the General Corporation Law of the State of
               Delaware relating to proxies, and judicial interpretations
               thereunder, as if the Trust were a Delaware corporation and the
               Holders of the Securities were stockholders of a Delaware
               corporation.

                      (iii) Each meeting of the Holders of a class or series of
               Securities shall be conducted by the Regular Trustees or by such
               other Person that the Regular Trustees may designate.

of Preferred Securities of IAC Capital Trust (the "Trust") are set forth below

in the Declaration):

               1. DESIGNATION AND NUMBER. Preferred Securities of the Trust with
an aggregate liquidation amount in the assets of the Trust of One Hundred
Seventy-two Million Five Hundred Thousand Dollars ($172,500,000) (including up
to Twenty-two Million Five Hundred Thousand Dollars ($22,500,000) issuable upon
exercise of the overallotment option set forth in the Purchase Agreement dated
as of __________, 1997 among the Trust, Irvine Apartment Communities, Inc.

               2. DISTRIBUTIONS. (a) Subject to the rights of Holders of any
series of Preferred Securities which the Trust may issue in the future which
rank on a parity with the Series A Preferred Securities in respect of
distributions, the Holders of outstanding Series A Preferred Securities will be
entitled to receive, when, as and if declared by the Regular Trustees out of
funds legally available for the payment of distributions, cumulative
preferential cash distributions at the rate per annum of ____% (the
"Distribution Rate") of the stated liquidation amount of $25 per Series A
Preferred Security (the "Stated Value"). Distributions on the Series A Preferred
Securities will be cumulative, will accrue from ___________, 199___, the
original issue date of the Series A Preferred Securities, and will be payable
quarterly in arrears on ___________, _______________, and ________________ (each
a "Series A Distribution Payment Date") of each year,
commencing on __________________________________, 1998. The amount of
distributions payable for any period will be computed on the basis of a 360-day
year of twelve 30-day months and for any period shorter than a full quarterly
period for which distributions are computed, the amount of the distribution
payable will be computed on the basis of the actual number of days elapsed in
such a 30-day month. If any Series A Distribution Payment Date is not a Business
Day, the payment of the distribution to be made on such Series A Distribution
Payment Date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay) except that
if such Business Day is in the next succeeding calendar year, such payment shall
be made on the immediately preceding Business Day, in each case with the same
force and effect as if made on such Series A Distribution Payment Date. While
the Series A Preferred Securities remain in book-entry only form, the relevant
record dates shall be one Business Day prior to the relevant Series A
Distribution Payment Date, and if the Series A Preferred Securities are no
longer in book-entry only form, the Regular Trustees shall have the right to
select relevant record dates, which shall be not less than 10 nor more than 50
days preceding the applicable Series A Distribution Payment Date.

               (b) Distributions on the Series A Preferred Securities shall
accrue on a daily basis commencing on the date of original issuance of the
Series A Preferred Securities, will accrue whether or not the Trust has
earnings, whether or not there are funds legally available for the payment of
such distributions and whether or not such distributions are declared. Accrued
distributions will accumulate, to the extent not paid, as of the Series A
Distribution Payment Date on which they first become payable. Accumulated and
unpaid distributions will not bear interest.

               (c) So long as any Series A Preferred Securities are outstanding,
no distribution shall be paid or declared on or with respect to the Common
Securities or any other series of outstanding Preferred Securities ranking
junior to the Series A



                                        2

<PAGE>   3

Preferred Securities as to the payment of distributions to the Series A
Preferred Securities, nor shall any sum or sums be set aside for or applied to
the purchase or redemption of the Series A Preferred Securities or any other
series of outstanding Preferred Securities or the purchase, redemption or other
acquisition for value of any Common Securities or any Preferred Securities of a
series ranking junior as to the payment of distributions unless, in each case,
full cumulative distributions accumulated on all Series A Preferred Securities
and all other series of outstanding Preferred Securities ranking on a parity
with the Series A Preferred Securities as to the payment of distributions have
been paid in full, provided that the foregoing will not prohibit distributions
payable solely in Common Securities or Preferred Securities of a series ranking
junior to the Series A Preferred Securities as to the payment of distributions.
When distributions have not been paid in full upon the Series A Preferred
Securities on the applicable Series A Distribution Payment Date (or a sum
sufficient for such full payment is not yet set apart therefor), all
distributions declared and paid on the Series A Preferred Securities and any
other series of outstanding Preferred Securities ranking on a parity with the
Series A Preferred Securities as to the payment of distributions shall be
declared and paid so that the amount of distributions declared and paid on the
Series A Preferred Securities and such other series of Preferred Securities
shall in all cases bear to each other the same ratio that the respective
distribution rights of Series A Preferred Securities and such other series of
Preferred Securities (which shall not include any accumulation in respect of
unpaid distributions for prior distribution periods if such other series of
Preferred Securities do not have cumulative distribution rights) bear to each
other.

               (d) Holders of Series A Preferred Securities shall not be
entitled to any distributions whether payable in cash, property, or otherwise in
excess of the full cumulative distributions as herein provided. Distributions
with respect to the dissolution, liquidation, winding-up or termination of the
Trust shall be governed by Paragraph 4 hereof.

               3. RESTRICTIONS ON OWNERSHIP AND TRANSFER OF SERIES A PREFERRED
SECURITIES. The Ownership Limit applicable to the Series A Preferred Securities
shall be 9.8%.

               4. LIQUIDATION DISTRIBUTION UPON DISSOLUTION. Subject to the
rights of the Holders of any other series of Preferred Securities which the
Trust may issue in the future which rank on a parity with the Series A Preferred
Securities upon any voluntary or involuntary dissolution, liquidation,
winding-up or termination of the Trust, the Holders of the Series A Preferred
Securities will be entitled to receive upon any such dissolution, liquidation,
winding-up or termination of the Trust out of the



                                        3

<PAGE>   4

assets of the Trust legally available for distribution, after payment or
provision for debts and other liabilities of the Trust (to the extent not
satisfied by IAC, L.P. as provided in the Declaration), an amount per Series A
Preferred Security equal to the Stated Value, plus accrued and unpaid
distributions thereon to the date of payment (such amount being the "Liquidation
Distribution") and no more. If, upon any such liquidation, dissolution,
winding-up or termination, there are insufficient assets to permit full payment
to the holders of Series A Preferred Securities and any other series of
outstanding Preferred Securities ranking on a parity upon liquidation,
dissolution, winding-up or termination of the Trust with the Series A Preferred
Securities, the holders of Series A Preferred Securities and such other series
of Preferred Securities shall be paid ratably in proportion to the full
distributable amounts to which Holders of Series A Preferred Securities and such
other series of Preferred Securities are respectively entitled upon liquidation,
dissolution, winding-up or termination. The full preferential amount payable to
Holders of the Series A Preferred Securities and such other series of Preferred
Securities upon any such liquidation, dissolution, winding-up or termination
will be paid in full before any distribution or payment is made to the Holders
of Common Securities or Preferred Securities of any series ranking junior to the
Series A Preferred Securities as to the payment of distributions upon
liquidation, dissolution, winding-up or termination of the Trust.

               5. STATED MATURITY AND REDEMPTION. (a) The Series A Preferred
Securities shall mature and the Stated Value thereof shall be due and payable on
December 31, 2092 (the "Stated Maturity Date") whether or not the term of the
Partnership is extended. On the Stated Maturity Date the holders of Series A
Preferred Securities shall be entitled to receive, upon surrender of their
certificates for the Series A Preferred Securities, out of funds legally
available for distribution an amount in cash equal to the Stated Value per
Series A Preferred Security, plus accrued and unpaid distributions thereon to
the date of payment (the "Stated Maturity Price") and no more.

               (b) Upon the repayment of a series of Preferred L.P. Units, in
whole or in part, whether at maturity, upon termination of IAC, L.P., upon
redemption or otherwise, or under certain circumstances upon the occurrence of
a Special Event (as defined in the Partnership Agreement), the proceeds of such
repayment will be promptly applied to redeem a series of Preferred Securities
with economic terms substantially similar to the economic terms of the series of
Preferred L.P. Units being redeemed or repaid, having an aggregate stated value
equal to the aggregate stated value of the Preferred L.P. Units so repaid or
redeemed, upon not less than 30 nor more than 60 days' notice, subject to the

outstanding Preferred Securities, at the applicable redemption price. "Series A
Redemption Price" means, as it relates to the Series A Preferred Securities, $25
per Series A Preferred Security plus an amount equal to accrued and unpaid
distributions thereon to the date of redemption, payable in cash; provided that
the Trust may not redeem fewer than all the outstanding Series A Preferred
Securities unless all accrued and unpaid distributions have been paid on all
Series A Preferred Securities for all quarterly distribution periods terminating
on or prior to the date of redemption.

               (c) If fewer than all the outstanding Series A Preferred
Securities are to be so redeemed, the Series A Preferred Securities to be
redeemed will be redeemed as described in Paragraph 5(e)(ii) below. If a partial
redemption would result in the delisting of the Series A Preferred Securities by
any national securities exchange or other organization on which the Series A
Preferred Securities are then listed, the Trust may only redeem Series A
Preferred Securities in whole.

               (d) Except in the case of a Special Event, the Series A Preferred
Securities may not be redeemed prior to ____________________.

               (e) (i) The Regular Trustees, on behalf of the Trust, will
provide notice of any redemption of the Series A Preferred Securities to the
Holders of record thereof not less than 30 nor more than 60 days prior to the
date of redemption and in the case of a mandatory repayment of the Series A
Preferred Securities on the Stated Maturity Date will provide notice of such
repayment not less than 30 nor more than 60 days prior to the Stated Maturity
Date. Such notice shall be provided by mailing notice of such redemption or
mandatory repayment, first class postage prepaid, to each Holder of Series A
Preferred Securities to be redeemed or to all Holders in the event of a
mandatory repayment on the Stated Maturity Date, at such Holder's address as it
appears on the transfer records of the Trust. Each notice shall state, as
appropriate, the following:

        (A) the redemption date or the Stated Maturity Date;

        (B) the Series A Redemption Price or the Stated Maturity Price;

        (C) the place or places where certificates for the Series A Preferred
Securities may be surrendered for payment;



                                        5

<PAGE>   6



        (D) the number of the Series A Preferred Securities to be redeemed from
each Holder;

        (E) that payment of the Series A Redemption Price or the Stated Maturity
Price will be made upon presentation and surrender of such Series A Preferred
Securities; and

        (F) that on or after the Stated Maturity Date or the redemption date
distributions on the Series A Preferred Securities to be redeemed or repaid
will cease to accrue.

No failure to give or defect in a notice of redemption shall affect the validity
of the proceedings for redemption except as to the Holder to which notice was
defective or not given.

               (ii) In the event of any redemption of Series A Preferred
Securities in part, Series A Preferred Securities registered in the name of and
held of record by DTC (or the successor Clearing Agency) or any other nominee
will be redeemed from, and the distribution of the proceeds of such redemption
will be made to, each Clearing Agency Participant (or person on whose behalf
such nominee holds such securities) in accordance with the procedures applied by
such Clearing Agency or nominee. If the Series A Preferred Securities are no
longer in book-entry form, the provisions of Paragraph 10 hereof shall apply to
any redemption of the Series A Preferred Securities in part.

               (iii) If notice (which notice will be irrevocable) has been given
to the Holders of Series A Preferred Securities as provided above, then, by
12:00 noon, New York City time, on the redemption date or the Stated Maturity
Date, as the case may be, provided that IAC, L.P. has paid the Property Trustee
a sufficient amount of cash in connection with the redemption or maturity of the
series of Preferred L.P. Units having economic terms substantially similar to
the Series A Preferred Securities, the Property Trustee will deposit irrevocably
in trust for the benefit of the Series A Preferred Securities being redeemed or
repaid funds sufficient to pay the applicable Series A Redemption Price or
Stated Maturity Price, as the case may be, and will give irrevocable
instructions and authority to pay such Series A Redemption Price or Stated
Maturity Price, as the case may be, to the Holders of the Series A Preferred
Securities entitled thereto. If notice shall have been given as provided above
and funds deposited as required, then upon the date of such deposit,
distributions will cease to accrue on the Series A Preferred Securities called
for redemption or to be repaid, as the case may be, such Series A Preferred
Securities will no longer be



                                        6

<PAGE>   7

deemed to be outstanding and all rights of Holders of such Series A Preferred
Securities so called for redemption or to be repaid, as the case may be, will
cease, except the right of the Holders of such Series A Preferred Securities to
receive the applicable Series A Redemption Price or Stated Maturity Price, as
the case may be, but without interest thereon. Neither the Trustees nor the
Trust shall be required to register or cause to be registered the transfer of
any Series A Preferred Securities which have been so called for redemption. If
the Stated Maturity Date or any date fixed for redemption of Series A Preferred
Securities is not a Business Day, then payment of the Series A Redemption Price
or the Stated Maturity Price, as the case may be, payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such Business Day
falls in the next calendar year, such payment will be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on the Stated Maturity Date or such date fixed for redemption. If payment of the
Series A Redemption Price or the Stated Maturity Price, as the case may be, in
respect of the Series A Preferred Securities is improperly withheld or refused
and not paid, distributions on such Series A Preferred Securities will continue
to accrue from the original redemption date or the Stated Maturity Date, as the
case may be, to the date of payment, in which case the actual payment date will
be used for purposes of calculating the Series A Redemption Price or the Stated
Maturity Price, as the case may be.

               (iv) The Holders of Series A Preferred Securities at the close of
business on a distribution record date will be entitled to receive the
distribution payable with respect to such Series A Preferred Securities on the
corresponding Series A Distribution Payment Date notwithstanding the redemption
thereof between such distribution record date and the corresponding Series A
Distribution Payment Date or the Trust's default in the payment of the
distribution due. Except as provided above, the Trust will make no payment or
allowance for unpaid distributions, regardless of whether in arrears, on Series
A Preferred Securities called for redemption.

               (v) Subject to the foregoing and applicable law (including,
without limitation, United States federal securities laws), IAC, L.P. or any of
its subsidiaries may at any time and from time to time purchase outstanding
Series A Preferred Securities by tender, in the open market or by private
agreement unless at such time, IAC, L.P. would be prohibited from purchasing or
redeeming Series A Preferred L.P. Units pursuant to the terms thereof.

               (f) The Series A Preferred Securities do not have the benefit of
any sinking fund.

               6. VOTING RIGHTS. (a) Except as provided under Paragraph 6(b)
below and as otherwise required by law and the Declaration, the Holders of the
Series A Preferred Securities will have no voting rights.

               (b) If the Trust fails to make distributions in full on the
Series A Preferred Securities for 6 consecutive quarterly distribution periods
(an "Appointment Event"), then the Holders of the Series A Preferred Securities
(voting separately as a class with all other series of Preferred Securities upon
which like voting rights have been conferred and are then exercisable) will be
entitled, by the vote of Holders of such Preferred Securities representing a
Majority in aggregate liquidation amount of such outstanding Preferred
Securities, to appoint, subject to Section 4.2(a)(ii)(B) of the Declaration, a
Special Regular Trustee. Any Holder of Series A Preferred Securities (other than
IAC, Inc. or IAC, L.P. or any of their affiliates) shall have the right to
nominate any Person to be appointed as Special Regular Trustee. For purposes of
determining whether the Trust has failed to pay distributions in full for 6
consecutive quarterly distribution periods, distributions shall be deemed to
remain in arrears, notwithstanding any payments in respect thereof, until full
cumulative distributions have been or contemporaneously are paid with respect to
all quarterly distribution periods terminating on or prior to the date of
payment of such cumulative distributions. Not later than 30 days after such
right to appoint a Special Regular Trustee arises, the Regular Trustees ,
subject to Section 4.2(a)(ii)(B) of the Declaration, will convene a meeting for
the purpose of appointing a Special Regular Trustee. If the Regular Trustees
fail to convene such meeting within such 30-day period, the Holders of Series A
Preferred Securities and any other series of Preferred Securities upon which
like voting rights have been conferred and are exercisable representing an
aggregate of 10% in liquidation amount of such outstanding Preferred Securities
will be entitled to convene such meeting. If, at any such meeting, Holders of
less than a Majority in aggregate liquidation amount of Preferred Securities of
all series entitled to vote for the appointment of a Special Regular Trustee
vote for such appointment, no Special Regular Trustee shall be appointed.

               If any proposed amendment or modification to the Declaration
would materially and adversely affect the powers, privileges, preferences or
special rights of the Series A Preferred Securities, then the Holders of
outstanding Series A Preferred Securities will be entitled to vote on such
amendment or proposal as a class and such amendment or proposal shall not be
effective except with the approval of the Holders of Series A Preferred
Securities representing 66-2/3% in liquidation amount of outstanding Series A
Preferred Securities; provided, however, that any such amendment or
modification which would (i) increase the number of authorized Securities



                                        8

<PAGE>   9

that the Trust is authorized to issue or (ii) authorize, create or issue any
additional series of Preferred Securities on a parity with or junior to the
Series A Preferred Securities as to distributions or upon liquidation,
dissolution, winding-up or termina tion of the Trust shall be deemed not to
materially and adversely affect such power, special rights, preferences or
privileges; and provided, further, if Holders of Series A Preferred Securities
have a right to vote as provided in this Paragraph but such amendment or
modification arises out of, or is substantially similar to, an amendment or a
modification of the Partnership Agreement as described in the following
paragraph and with respect to which the Property Trustee is required to obtain
the direction of Holders of Series A Preferred Securities as described below,
then to the extent permitted by applicable law, no separate vote pursuant to the
Declaration shall be required and the vote obtained in connection with the
Property Trustee seeking the direction of Holders of Series A Preferred
Securities shall constitute complete and sufficient action with respect to such
amendment or modification of the Declaration.

               In the event the consent or vote of the Property Trustee, as the
Holder of the Series A Preferred L.P. Units of IAC, L.P., is required with
respect to any amendment or modification of the Partnership Agreement, the
Property Trustee shall request the written direction of the Holders of the
Series A Preferred Securities with respect to such amendment or modification and
the Property Trustee shall vote with respect to the Series A Preferred L.P.
Units and such amendment or modification as directed by a Majority in aggregate
liquidation amount of the Series A Preferred Securities voting together as a
single class; provided that where such amendment or modification under the
Partnership Agreement requires the consent of Holders of Series A Preferred L.P.
Units representing a specified percentage greater than a Majority in aggregate
liquidation amount of the Series A Preferred L.P. Units, the Property Trustee
may only give such consent at the direction of the Holders of Series A Preferred
Securities representing such specified percentage of the aggregate liquidation
amount of the Series A Preferred Securities.

               Any required approval or direction of Holders of Series A
Preferred Securities may be given at a separate meeting of Holders of Series A
Preferred Securities convened for such purpose, at a meeting of all of the
Holders of Preferred Securities of the Trust or pursuant to written consent. The
Regular Trustees will cause a notice of any meeting at which Holders of Series A
Preferred Securities are entitled to vote, or of any matter upon which action by
written consent of such Holders is to be taken, to be mailed to each Holder of
record of Series A Preferred Securities. Each such notice will include a
statement setting forth (i) the date of such meeting or the date by which such
action is to be taken, (ii) a description of any resolution proposed for
adoption at such meeting on which such Holders are entitled



                                        9

<PAGE>   10



to vote or of such matter upon which written consent is sought and (iii)
instructions for the delivery of proxies or consents.

               No vote or consent of the Holders of Series A Preferred
Securities will be required for the Trust to redeem and cancel Preferred
Securities of any series.

               Notwithstanding that Holders of Series A Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Series A Preferred Securities at such time that are owned by IAC, Inc.,
IAC, L.P. or by any entity directly or indirectly controlling or controlled by
or under direct or indirect common control with IAC, Inc. or IAC, L.P. shall not
be entitled to vote or consent and shall, for purposes of such vote or consent,
be treated as if they were not outstanding.

               7. RANKING. The Series A Preferred Securities rank, with respect
to distributions and rights upon liquidation, dissolution, winding-up or
termination of the Trust, (i) senior to the Common Securities and (ii) on a
parity with all other series of Preferred Securities issued by the Trust unless
the terms of such other series specifically provide that such other series
ranks junior to the Series A Preferred Securities.

               9. CONVERSION RIGHTS. Except as otherwise provided in Article
VIII of the Declaration regarding exchanges for Excess Preferred Securities, the
Series A Preferred Securities are not convertible into or exchangeable or
exercisable for any other property or securities of the Trust, IAC, Inc. or IAC,
L.P..

               10.  TRANSFER, EXCHANGE, METHOD OF PAYMENTS.
In the event the Series A Preferred Securities do not remain in book-entry only
form, the following provisions shall apply:

        Payment of distributions and payments on redemption or at the Stated
Maturity of the Series A Preferred Securities will be payable, the transfer of
the Series A Preferred Securities will be registerable, and Series A Preferred
Securities will be exchangeable for Series A Preferred Securities of other
denominations of a like aggregate liquidation amount, at the principal corporate
trust office of the Property Trustee in The City of New York; provided that
payment of distributions may be made at the option of the Regular Trustees on
behalf of the Trust by check mailed to the address of the persons entitled
thereto and that the payment on redemption or at the Stated Maturity of any
Series A Preferred Security will be made only upon surrender of such Preferred
Security to the Property Trustee.


                                       10

<PAGE>   11

        If fewer than all of the Series A Preferred Securities are to be
redeemed, the Property Trustee shall select Series A Preferred Securities to be
redeemed by lot or pro rata (as nearly as practicable without creating
fractional Series A Preferred Securities) or in some other equitable manner
determined by the Property Trustee upon consultation with the Regular Trustees.

        In the event of any redemption of Series A Preferred Securities in part,
the Trust shall not be required to (i) issue, register the transfer of or
exchange any Series A Preferred Securities during a period beginning at the
opening of business 15 days before any selection for redemption of Series A
Preferred Securities and ending at the close of business on the earliest date on
which the relevant notice of redemption is deemed to have been given to all
Holders of Series A Preferred Securities to be redeemed and (ii) register the
transfer of or exchange any Series A Preferred Securities so selected for
redemption, in whole or in part, except the unredeemed portion of any Series A
Preferred Securities being redeemed in part. Holders of Series A Preferred
Securities shall surrender such Series A Preferred Securities at the place
designated in the notice of redemption and shall be entitled to the Series A
Redemption Price upon such redemption following such surrender.

               Upon presentation of any Certificate for Series A Preferred
Securities redeemed in part only, the Trust shall execute and deliver, at the
expense of the Trust, a new Certificate equal to the unredeemed portion of the
Certificate so presented.

               11. NO PREEMPTIVE RIGHTS. The Holders of Preferred Securities
shall have no preemptive rights to subscribe to any additional Preferred
Securities or Common Securities.

               12. MISCELLANEOUS. Upon issuance, the Series A Preferred
Securities will be fully paid and non-assessable. This Certificate of Terms
shall constitute a part of the Declaration.
