  8 1/4% SERIES A REIT TRUST ORIGINATED PREFERRED SECURITIES(SM)("TOPRS(SM)")
    
            (LIQUIDATION AMOUNT $25 PER SERIES A PREFERRED SECURITY)
                         ------------------------------
 
   
    The 8 1/4% 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 8 1/4% 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. The Series A Preferred Securities and
the Series A Preferred L.P. Units have a stated maturity of December 31, 2092,
which corresponds to the term of the Operating Partnership.
    
 
                                                        (continued on next page)
 
    The Series A Preferred Securities have been approved for listing on the New
York Stock Exchange, Inc. (the "NYSE"), subject to official notice of issuance.
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 109 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 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 L.P. Units will rank on a parity with all other series
  of Preferred L.P. Units issued by the Operating Partnership unless such other
  series states that such series ranks junior to the Series A Preferred L.P.
  Units.
    
 
- - 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.

    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,

     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 8 1/4% 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 March 31, June 30, September 30
and December 31 of each year, commencing on March 31, 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 8 1/4% 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 March 31, June
30, September 30 and December 31 of each year, commencing March 31, 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 be able to 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 the Series A Preferred Securities -- Distributions."
 
   
     Except as described below, the Series A Preferred L.P. Units are not
redeemable prior to December 31, 2002. On or after December 31, 2002, 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 currently intends to 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.

     Upon consummation of the Offering, the Trust will operate as an equity real
estate investment trust (a "REIT") under the Internal Revenue Code of 1986, as
amended (the "Code"). To ensure that the Trust maintains its qualification as a
REIT, ownership by any person is generally limited to 9.8% of the outstanding
Series A Preferred Securities, with certain exceptions.

                               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 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. 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."
 
                           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
 
                                        5
<PAGE>   6
 
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 31, 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 31, 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 31,
1997) limited partnership interest in the Operating Partnership.
 
     As of September 30, 1997, the Operating Partnership owned and operated
14,991 units in 51 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 being experienced by the State of California provides the
Operating Partnership with 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 development and operating performance of the Existing
Communities located on the Irvine Ranch and the existence of opportunities for
the development of additional apartment communities on the Irvine Ranch. Most
important among these factors are:
 
     - The 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;
 
                                        6
<PAGE>   7
 
     - The limited supply of developable land, other than on the Irvine Ranch,
       adjacent to 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 quality of the 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 employment centers, the Pacific Ocean, quality
       schools, and 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
rental demographics and economic growth prospects similar to those on the Irvine
Ranch.

                                  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 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 L.P. Units rank junior to all existing and future
       debt and other liabilities of the Operating Partnership and its
       subsidiaries 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.
    
 
     - 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
       Preferred 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 that 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 interests of The Irvine Company may not be
       consistent with the interests of other holders of L.P. Units or those of
       holders of the Series A Preferred Securities.
 
     - 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.
 
                                        9
<PAGE>   10
 
     - 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:
 
      -- 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. 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.
 
                                 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 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 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 31, 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 "Federal Income Tax Consequences."
 
                             CONFLICTS OF INTEREST
 
     The Irvine Company, through its representation on the Board of Directors of
the Company and its ability to terminate the Land Rights Agreement under certain
circumstances, has significant influence over the affairs of the Company and
thus the Operating Partnership, including the ability to block certain actions
such as amendments to the Company's Articles of Incorporation or Bylaws or the
Partnership Agreement and sales of all or substantially all of the Operating
Partnership's assets. The influence of The Irvine Company over the
 
                                       11
<PAGE>   12
 
affairs of the Operating Partnership may not be consistent with the interests of
other holders of L.P. Units or those of holders of the Series A Preferred
Securities. In addition, The Irvine Company determines which land on the Irvine
Ranch is designated for apartment community development and therefore which land
is eligible for purchase by the Operating Partnership pursuant to the Land
Rights Agreement. The feasibility and development of additional 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 entitle land for development of additional
apartment communities at a rate consistent with prior development. See "Risk
Factors -- Conflicts of Interest," "-- 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" and
"-- 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 occurrence and continuance of a Tax Event (as
                             defined herein) or Investment Company Act Event (as
                             defined herein). The redemption price (other than

                             distributions) will be payable solely out of the

                             Partnership redeems Series A Preferred L.P. Units,
                             the Trust must redeem in cash a series of Preferred

                             Series A Preferred L.P. Units are redeemed, the

                             Series A Preferred Securities will be represented
                             by one or more permanent global securities in fully

                             require that certain purchasers of securities take

                             Such laws may impair the ability to transfer

(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, as adjusted, 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, as
    adjusted, to interest expense and preferred securities distributions for
    each of the periods indicated was equal to the ratio of EBITDA, as adjusted,
    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 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>   18
 
     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 "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 Trust currently intends to redeem the Series A Preferred
Securities. 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
"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 to the Declaration. Such an amendment
to the Declaration would require the affirmative vote of a majority of the
Regular Trustees. Series A Preferred Securities have no voting rights with
respect to such an amendment.
 
                                       18
<PAGE>   19
 
     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 the 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 currently intends to 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 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
 
                                       19
<PAGE>   20
 
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 31, 1997, The Irvine
Company owned 1,533,385 shares of Common Stock of the Company and 24,737,410
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 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)
    
 
                                       20
<PAGE>   21
 
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.
 
     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.
 
                                       21
<PAGE>   22
 
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 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
 
                                       22
<PAGE>   23
 
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 the Series A Preferred Securities have been
approved for listing on the NYSE, subject to official notice of issuance, 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. 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 is a limited purpose financing
vehicle established by the Company and the Operating Partnership and 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 similar 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
 
                                       24
<PAGE>   25
 
than in connection with the purposes of the Trust or other than as required or
authorized by the Declaration. 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
     limited to those established by law and agreements between such Preferred
     Security Indirect Owners and the DTC and/or its participants. With respect
     to Series A Preferred Securities registered in the name of and held by the
     DTC or its nominee, all notices and other communications required under the
     Declaration shall be given to, and all distributions on such Preferred
     Securities shall be given or made to, the DTC (or its successor).

     The specific terms of the depositary arrangement with respect to the Series
A Preferred Securities are set forth under "Description of the Series A
Preferred Securities -- Book-Entry Only Issuance -- The Depository Trust

     In the Declaration, the Operating Partnership has agreed to reimburse all
costs, expenses and liabilities of the Trust, including the fees and expenses of
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
Trust Securities and withholding taxes on such distributions. The foregoing
obligations of the Operating Partnership under the Declaration are for the
benefit of, and shall be enforceable by, any person to whom any such debts,
obligations, costs, expenses and taxes are owed (a "Creditor") whether or not
such Creditor has received notice thereof. Any such Creditor may enforce such
obligations of the Operating Partnership directly against the Operating
Partnership, and the Operating Partnership and the Company have irrevocably
waived any right or remedy to require that any such Creditor take any action
against the Trust or any other person before proceeding against the Operating
Partnership. The Operating Partnership and the Company have agreed in the
Declaration to execute such additional agreements as may be necessary or
desirable in order to give full effect to the foregoing.

                              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.
 
                                       27
<PAGE>   28
 
                                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 $144.3 million ($166.1 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 December 31,
1997, the Credit Facility had an outstanding balance of approximately $75.0
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.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 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.

<PAGE>   34
 
     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.
 
                                       35
<PAGE>   36
 
     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 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
 
                                       36
<PAGE>   37
 
or down reflecting the credit ratings on the Operating Partnership's senior
unsecured long-term indebtedness. 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."

</TABLE>
 
     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

costs which substantially extend an existing asset's useful life. Capital
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 31, 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 31, 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 31, 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 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.
 
                                       41

     The Operating Partnership believes that a variety of factors have
contributed to the development and operating performance of the Existing
Communities located on the Irvine Ranch and the existence of opportunities for
the development of additional apartment communities on the Irvine Ranch. Most
important among these factors are:
 
     - The 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 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 quality of the 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 employment centers, the Pacific Ocean, quality
       schools, and 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
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 opportunities for new development
within its primary market, and in similar 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.

  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 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 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 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>   45
 
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
<PAGE>   46
 
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 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 their 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:

(1) Excludes The Villas of Renaissance, an apartment community acquired by the
    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>   49
 
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>   50
 
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>   51
 
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>   52
 
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>   53
 
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>   54
 
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.
 
PRINCIPAL EXECUTIVE OFFICES
 
     The principal executive offices of the Operating Partnership are located at

                             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 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 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
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 those of 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 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
 
                                       55
<PAGE>   56
 
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 31, 1997, The Irvine
Company owned 1,533,385 shares of Common Stock of the Company and 24,737,410
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 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."

                  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
28.1% on a pro forma basis after
    
 
                                       57
<PAGE>   58
 
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
 
                                       58
<PAGE>   59
 
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 July 31, 2020. The Irvine Company and Mr. Bren will remain
prohibited from engaging in any such activity off
 
                                       59

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" and
"Conflicts of Interest." 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.

     will be waived. The Irvine Company has the right, once in every twelve
     month period beginning on December 8 of each year, generally to exchange up
     to one third of the Common L.P. Units for shares of Common Stock, at an
     exchange ratio of one Common L.P. Unit for each share of Common Stock,
     subject to adjustment. The Company's Articles of Incorporation place a

     beneficially own 57.9% of the Common Stock. Assuming the exchange of all
     Common L.P. Units beneficially owned by The Irvine Company and TRC, all

 (7) Mr. Moran resigned as the Executive Vice President, Chief Financial Officer
     and Secretary of the Company in December 1996. Since his resignation, Mr.

     March 1997. Since his resignation, Mr. Rose has not made a Form 4 or 5
     filing under the Securities Exchange Act of 1934, as amended, and
     therefore, the Operating Partnership has no information for Mr. Rose after
     such date.

the sole limited partners of, and holding in the aggregate a 61.0% partnership
interest in, the Operating Partnership; (iii) the transfer of all 43 apartment

Operating Partnership; and (iv) the assumption by the Operating Partnership of
certain debt of The Irvine Company related to such apartment communities.
 
     On August 9, 1995, the Company sold, pursuant to a public offering
5,175,000 shares of Common Stock at $17.25 per share. Concurrently with such
offering, The Irvine Company, pursuant to its rights under the Partnership

     The Company and The Irvine Company have entered into an administrative
services agreement, as amended, pursuant to which The Irvine Company provides
the Company with certain administrative services, including, but not limited to,

financed, bore fixed interest rates of 5.75% at September 30, 1997 and December
31, 1996, are fully amortizing, and mature in 2015 and 2024. Interest incurred

     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
 
                                       73
<PAGE>   74
 
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 Partnership, of which 191,011 Common L.P. Units are
exchangeable for Common Stock of the Company on a
 
                                       74

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 20,000 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 banking institution. 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.
    
 
     The Series A Preferred Securities have been approved for listing on the
NYSE, subject to official notice of issuance, under the symbol "IAC Pr A."
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 to outstanding series of Preferred
Securities (and any related series of Excess Preferred Securities as described
 
                                       76
<PAGE>   77
 
   
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 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 transfer that resulted in the
Excess Preferred Securities or (ii) the price per security received by the
original
 
                                       77
<PAGE>   78
 
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 a majority of the Regular Trustees. 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 preferential cash distributions at the rate per annum of 8 1/4% 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 March 31, June 30, September 30 and December 31 (each a "Series A
Distribution Payment Date") of each year, commencing on March 31, 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 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
    
 
                                       78
<PAGE>   79
 
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 be able to 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 December 31,
2002 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, the Trust currently intends to redeem for cash at the
Redemption Price Series A Preferred Securities having an aggregate liquidation
amount equal to the Series A Preferred L.P. Units so repaid. 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 interdealer quotation system 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,
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.
 
                                       80
<PAGE>   81
 
     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.

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
 
                                       82
<PAGE>   83
 
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 for or on behalf of a series of
Preferred Securities, a majority in aggregate liquidation amount of the
Preferred Securities of such series may direct the Property Trustee to take such
legal action. If the Property Trustee fails to enforce its rights under the
Partnership Agreement with respect to a series of Preferred L.P. Units, any
holder of Preferred Securities that is adversely affected thereby 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
 
                                       83
<PAGE>   84
 
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 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
 
                                       84
<PAGE>   85
 
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 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, (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.
 
                                       85
<PAGE>   86
 
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.
 
                                       86

     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 8 1/4% 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 March 31, June 30, September 30 and
December 31 of each year (each a "Series A Preferred L.P. Unit Distribution
Payment Date"), commencing on March 31, 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.
 
                                       89
<PAGE>   90
 
     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
 
                                       90
<PAGE>   91
 
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 December 31, 2002. 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 would
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
 
                                       91
<PAGE>   92
 
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 accrue 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 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.
 
                                       92

     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 December 31,
2002, 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 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 Partnership Agreement with respect to the Preferred L.P.
Units of the Operating Partnership held by the Trust. If the Property Trustee
fails to take legal action for or on behalf of a series of Preferred Securities,
the holders of a majority in aggregate liquidation amount of the Preferred
Securities of such series 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 Partnership Agreement
with respect to a series of Preferred L.P. Units, any holder of Preferred
Securities that is adversely affected thereby 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
 
                                       95
<PAGE>   96
 
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 December 31, 1997, The Irvine Company and its affiliates owned
24,737,410 Common L.P. Units in the aggregate exchangeable for Common Stock and
106,696 Common L.P. Units which are not exchangeable for Common Stock absent
approval of the stockholders of the Company. 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
 
                                       96
<PAGE>   97
 
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 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 "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.

                        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
 
                                       98
<PAGE>   99
 
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
 
                                       99
<PAGE>   100
 
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.
 
                                       100
<PAGE>   101
 
     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.

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
 
                                       102
<PAGE>   103
 
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 withheld with
respect to, each Non-U.S. Holder. These reporting requirements apply regardless
of whether
 
                                       103
<PAGE>   104
 
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 $.50 per Series A Preferred Security. The Underwriters may allow, and
such dealers may reallow, a discount not in excess of $.30 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 18,020 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.
    
 
                                       105
<PAGE>   106
 
     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
$.7875 per Series A Preferred Security (or $4,725,000 in the aggregate)
($5,433,750 in the aggregate if the Underwriters' over allotment option is
exercised in full) for the accounts of the several Underwriters.
    
 
     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.
 
     The Series A Preferred Securities have been approved for listing on the
NYSE, subject to official notice of issuance, under the symbol "IAC Pr A."
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 to 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
 
                                       106
<PAGE>   107
 
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.
 
     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 $36.8 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 "Certain Relationships
and Related Transactions -- Other Transactions."

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.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Partners
Irvine Apartment Communities, L.P.
 
     We have audited the accompanying consolidated balance sheets of Irvine
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
December 31, 1996. Our audits also included the financial statement schedule
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

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,

                (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.

NOTE 6 -- 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 service agreement covering
services for risk management, income taxes and other services of $108 for the
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
$6.0 million from The Irvine Company for the development of 207 rental units

approved the purchase in accordance with the Land Rights Agreement. The purchase
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.

     Directors' Stock Option Plan: The 1993 Stock Option Plan for Directors was
established with 100,000 shares of common stock that may be granted to
independent directors. Grants of fully vested options to purchase 5,000 shares
of common stock, and matching partnership units, at the market price on the
grant date were made to each independent director immediately following the
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.

     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.

                   NOTES TO UNAUDITED CONDENSED CONSOLIDATED
                              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.

                        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).
 
NOTE 4 -- PARTNERS' CAPITAL
 
     On February 20, 1997 the Company sold, in a public offering, 1.15 million
shares of common stock at $27.50 per share. Concurrently, The Irvine Company
(see Note 7), pursuant to its rights under the
 
                                      F-29

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.

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 as of January 1, 1996. As the Property was acquired on
June 30, 1997, the results of operations of the Property after June 30, 1997 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
January 1, 1996. 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
 
                                      F-34

     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).

                        INDEPENDENT ACCOUNTANTS' REPORT
 
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.

                         NOTES TO FINANCIAL STATEMENTS
 
                        YEAR ENDED DECEMBER 31, 1996 AND
                   SIX MONTHS ENDED JUNE 30, 1997 (UNAUDITED)
 
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.
 
NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES
 
     Revenue Recognition. Apartment units are leased for terms of one year or
less. Rental revenue is recognized on an accrual basis.
 
     Repair and Maintenance. Recurring repair and maintenance costs are expensed
as incurred.
