                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - ORGANIZATION

Irvine Apartment Communities, L.P., a Delaware limited partnership (the
"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. ("IAC, Inc.") obtained a general partnership interest in and
became the sole managing general partner of the Partnership. The Irvine Company
("TIC") transferred 42 apartment communities and a 99% interest in a limited
partnership which owns one apartment community to the Partnership. On June 7,
1999, IAC, Inc. was merged with and into TIC Acquisition LLC (the "Acquiror"), a
Delaware limited liability company indirectly wholly owned by TIC (the
"Merger"), with the Acquiror remaining as the surviving entity and renamed
Irvine Apartment Communities LLC ("IACLLC"). As a result of the Merger and a
related transaction in which TIC acquired an additional 74,523 common limited
partnership units, TIC and certain of its affiliates beneficially own and
control all of the outstanding common partnership units in the Partnership and
IACLLC became the sole general partner of the Partnership. At September 30,
1999, IACLLC had a 44.6% general partnership interest and TIC and certain of its
affiliates had a 55.4% common limited partnership interest in the Partnership.
The Partnership's management and operating decisions are under the unilateral
control of IACLLC.

The Partnership owns, operates and develops apartment communities in Orange
County, California and, beginning in 1997, other locations in California. As of
September 30, 1999, the Partnership owned 65 apartment communities representing
17,166 operating apartment units and 2,315 units under development
(collectively, the "Properties"). In May 1997, the Partnership broke ground on
its first property outside of the Irvine Ranch, an apartment community located
in Northern California's Silicon Valley. In March 1998, the Partnership and
Western National Property Management announced the formation of a strategic
alliance that, in April 1998, assumed all property management responsibilities
for the Partnership's Southern California portfolio. The new entity, Irvine
Apartment Management Company ("IAMC"), is owned 51% by the Partnership and 49%
by Western National Property Management. Effective January 1, 1999, IAMC's
property management responsibilities were expanded to include the Partnership's
entire portfolio.

IAC Capital Trust, a Delaware business trust (the "Trust"), was formed on
October 31, 1997. The Trust is a limited purpose financing vehicle established
by the Partnership. The Trust exists for the sole purpose of issuing preferred
securities and investing the proceeds in preferred limited partner units of the
Partnership.

NOTE 2 - BASIS OF PRESENTATION

The accompanying financial statements of the Partnership include the
consolidated accounts of its financially controlled subsidiaries. All
intercompany accounts and transactions have been eliminated in consolidation.
The Trust's investment in subsidiary relates to the redeemable Series A
preferred limited partner units in the Partnership. The Trust has less than a
controlling interest in the Partnership and accounts for its investment using
the equity method.


                                     Page 8
<PAGE>   11

During the fourth quarter of 1998, the Partnership adopted the Financial
Accounting Standards Board's Statement of Financial Accounting Standards No.
131, Disclosures About Segments of an Enterprise and Related Information
("Statement No. 131"). Statement No. 131 superseded FASB Statement No. 14,
Financial Reporting for Segments of a Business Enterprise. Statement No. 131
establishes standards for the way that public business enterprises report
information regarding reportable operating segments. The adoption of Statement
No. 131 did not affect the results of operations or financial position of the
Partnership.

The Partnership operates and develops apartment communities in California which
generate rental and other income through the leasing of apartment units to a
diverse base of renters. The Partnership separately evaluates the performance of
each of its apartment communities. However, because each of the apartment
communities has similar economic characteristics, facilities, services and
tenants, the apartment communities have been aggregated into a single dominant
apartment communities segment.

The Partnership evaluates performance and allocates resources primarily based on
the net operating income ("NOI") of individual apartment communities. NOI is
defined by the Partnership as rental and other income less property expenses and
real estate taxes. Accordingly, NOI excludes certain expenses included in the
determination of net income. NOI from apartment communities totaled $131,590,000
and $111,547,000 for the nine months ended September 30, 1999 and 1998,
respectively, and $45,403,000 and $39,855,000 for the three months ended
September 30, 1999 and 1998, respectively. All other segment disclosures are
included in the Partnership's Annual Report on Form 10-K/A for the year ended
December 31, 1998.

Profits and losses of the Partnership are generally allocated to the general
partner and to the common limited partners based on their respective ownership
interests in the Partnership. The holders of the Series A redeemable preferred
limited partner units and redeemable preferred securities are entitled to
distributions/dividends at an annual rate of 8 1/4% of the stated value per
unit/security. The stated value of each unit/security is $25. The holders of the
Series B redeemable preferred limited partner units are entitled to
distributions at an annual rate of 8 3/4% of the stated value per unit. The
stated value of each unit is $25.

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, 1999 and December 31, 1998, and the revenues and expenses for the
three and nine months ended September 30, 1999 and 1998. Actual results could
differ from those estimates.

Certain amounts in the 1998 financial statements have been reclassified to
conform with financial statement presentations in 1999.

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles ("GAAP") for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by GAAP 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 three and nine months ended September 30, 1999 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 1999. These financial statements should be read in conjunction with
the Consolidated Financial Statements and Notes thereto included in the
Partnership's and the Trust's Annual Report on Form 10-K/A for the year ended
December 31, 1998.

NOTE 3 - MORTGAGES AND NOTES PAYABLE

The Partnership's unsecured revolving credit facility and $100 million unsecured
term loan were amended in June 1999. The unsecured revolving credit facility and
unsecured term loan were amended and restated to accommodate the Merger and to
allow TIC and certain of its affiliates to beneficially own and control all of
the outstanding common partnership units in the Partnership and IACLLC to become
the sole general partner of the Partnership.

Tax-Exempt Mortgage Bond Financings: In September 1999, the Partnership
completed a $32 million offering of tax-exempt mortgage bond financings (the
"Bonds") for the construction of a 201-unit apartment community (the "Project")
at the Partnership's Park Place property. The Bonds represent loans payable that
are collateralized by a deed of trust granting a security interest in the
Project. Payment of principal and interest on the Bonds is secured by an
irrevocable letter of credit issued by Bank of America, National Association. As
a result, the Bonds were assigned the ratings of AA-/A1+, Aa1/P1 and AA/F1+ from
Standard & Poor's, Moody's and Fitch IBCA, respectively. Monthly principal and
interest payments are made to a trustee, which in turn pays the bondholders when
interest is due. The Bonds bear interest at a weekly-remarketed tax-exempt rate
and are due September 2029. The Bonds had an average floating interest rate
inclusive of fees of 4.2% in September 1999. As of September 30, 1999, the
Partnership has received proceeds of $6.6 million that represents the land and
transaction costs related to the Project. The remaining $25.4 million of
proceeds (included as a receivable in other assets) is held by a trustee and
will be funded for construction of the Project as costs are incurred.

Conventional Mortgage Financing: In September 1999, the Partnership obtained
$115 million of conventional mortgage financing from a financial institution.
The mortgage financing is secured by three of the Partnership's apartment
communities. The financing is due in monthly installments, bears interest at a
fixed rate of 7.37% and matures in September 2010. Proceeds from the financing
were used to repay the advances from affiliate (see Note 7) and for general
construction purposes.

On October 12, 1999, the Partnership obtained $70 million of conventional
mortgage financing from a financial institution. The mortgage financing is
secured by three of the Partnership's apartment communities. The financing is
due in monthly installments, bears interest at a fixed rate of 7.15% and matures
in October 2009. Proceeds from the financing will be used for general
construction purposes.

Unsecured Line of Credit: The Partnership's amended $125 million unsecured
revolving credit facility currently bears interest at LIBOR plus 0.65% or prime
and matures in June 2001. The interest rates under the credit facility are
adjusted up or down based on credit ratings on the Partnership's senior
unsecured long-term indebtedness. The Partnership may also enter into letters of
credit under the facility. Borrowings under the credit facility, which are
guaranteed by the general partner, are available to finance the Partnership's
ongoing rental property development and for general working capital needs. The
general partner and the 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, 1999, the
general partner and the Partnership were in compliance with all of these
covenants. At September 30, 1999, the general partner had letters of credit
under the facility totaling $63.5 million related to land and building purchases
(see "Capital Investments in New Development"). The letters of credit reduce the
remaining amount available under the line of credit. As of September 30, 1999,
there was no outstanding balance under the line of credit and $61.5 million was
available.



                                    Page 10
<PAGE>   13

Shelf Registration Statement: On May 14, 1997, the 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. On
October 1, 1997, the Partnership issued $100 million aggregate principal amount
of 7% senior unsecured notes pursuant to its shelf registration statement. In
June 1999, the Partnership cancelled the remaining availability of $250 million
under the shelf registration statement, including the Prospectus Supplement
dated April 9, 1998 filed for the future issuance of Medium-Term Notes. The
Partnership no longer plans to issue additional securities under the shelf
registration statement.

NOTE 4 - PARTNERS' CAPITAL

The Partnership paid cash distributions of $0.385 per common partnership unit in
the first quarter of 1999. The Partnership did not make any distributions on the
common partnership units in the second quarter of 1999. The Partnership paid
cash distributions of $0.354 per common partnership unit in the third quarter of
1999. During each of the first and second quarters of 1998, the Partnership paid
a cash dividend of $0.375 per common partnership unit. During the third quarter
of 1998, the Partnership paid a cash dividend of $0.385 per common partnership
unit.

NOTE 5 - MINORITY REDEEMABLE PREFERRED INTERESTS

In January 1998, the Trust issued 6.0 million of 8 1/4% Series A Preferred
Securities. The proceeds of $150 million were used to purchase an equivalent
amount of 8 1/4% Series A Preferred Limited Partner Units in the Partnership.
The Partnership used the $150 million of proceeds, net of costs and offering
expenses, all of which were paid by the Partnership, to repay the outstanding
balance on the Partnership's unsecured credit facility and to fund development.

In November 1998, the Partnership issued 2.0 million of 8 3/4% Series B
Preferred Limited Partner Units. The Partnership used the net proceeds to reduce
the outstanding balance on its unsecured line of credit.

The Partnership and the Trust paid cash distributions/dividends of $0.52 per
Series A preferred limited partner unit (or preferred security) on March 31,
1999, June 30, 1999, and September 30, 1999, respectively. The Partnership paid
cash distributions of $0.55 per Series B preferred limited partner unit on March
31, 1999, June 30, 1999, and September 30, 1999, respectively. During the first
quarter of 1998, the Partnership and the Trust each paid a cash
distribution/dividend of $0.42 per Series A preferred limited partner unit (or
preferred security). During each of the



                                    Page 11
<PAGE>   14

second and third quarters of 1998, the Partnership and the Trust each paid cash
distributions/dividends of $0.52 per Series A preferred limited partner unit (or
preferred security).

NOTE 6 - MERGER BETWEEN IAC, INC. AND THE ACQUIROR

On June 7, 1999, pursuant to the Merger, each outstanding share of IAC, Inc.'s
common stock was converted into the right to receive $34 in cash. The Merger and
related transactions were accounted for using the purchase method of accounting
in accordance with GAAP. Accordingly, the assets and liabilities of the
Partnership were adjusted to fair value. The step-up in basis related to
IACLLC's and TIC's investment in the Partnership of $511.8 million approximates
the fair value of the net assets acquired and was allocated to the assets of the
Partnership using push-down accounting based on the excess of their estimated
fair value over their historical carrying amount. Accordingly, $131.9 million of
the step-up in basis was allocated to land and $379.9 million was allocated to
buildings and improvements.

In conjunction with the Merger, IAC, Inc. and the Partnership entered into a
separate agreement whereby IAC, Inc. agreed to reimburse the Partnership for all
costs of the Merger incurred on IAC, Inc.'s behalf during 1999. In June 1999,
the Partnership was reimbursed for $6.6 million of Merger costs, of which $2.6
million had been incurred and expensed during the first quarter of 1999 and $4.0
million was incurred during the second quarter of 1999. Additionally, the
Partnership agreed to pay in cash the difference between $34 per share and the
exercise price of the vested stock options of IAC, Inc. which were outstanding
at the time of the Merger. During the second quarter of 1999, the Partnership's
cash payments related to vested stock options totaled $4.1 million, of which
$1.8 million was capitalized to real estate under development and $2.3 million
was charged to operations as general and administrative expenses.

A more detailed description of the Merger is included in the Partnership's
Current Report on Form 8-K filed with the Securities and Exchange Commission on
June 22, 1999.

NOTE 7 - CERTAIN TRANSACTIONS WITH RELATED PARTIES

Included in general and administrative expenses are charges from TIC pursuant to
an administrative services agreement covering services for risk management,
income taxes, human resources and other services totaling $112,000 and $142,000
for the nine months ended September 30, 1999 and 1998, respectively, and $12,000
and $42,000 for the three months ended September 30, 1999 and 1998,
respectively. TIC and the Partnership jointly purchase employee health care
insurance and property and casualty insurance. The Partnership incurred rent
totaling $454,000 and $366,000 for the nine months ended September 30, 1999 and
1998, respectively, and $165,000 and $123,000 for the three months ended
September 30, 1999 and 1998, respectively, related to leases with TIC that
expire at the end of 2003. IAMC incurred rent totaling $53,000 and $148,000 for
the three and nine months ended September 30, 1999, respectively, and $51,000
and $103,000 for the three and nine months ended September 30, 1998,
respectively, related to a lease with TIC. For the three and nine months ended
September 30, 1998, TIC contributed $1,293,000 and $3,763,000, respectively, in
connection with common limited partnership unit and stock issuances under the
dividend reinvestment and additional cash investment plan. TIC made no
contributions under the dividend reinvestment and additional cash investment
plan in 1999.

During the second and third quarters of 1999, all preacquisition costs which had
been incurred by the Partnership related to future development sites were
transferred at book value to TIC for the development and eventual operation of
the sites. As of September 30, 1999, TIC has reimbursed the Partnership for all
of the costs incurred to date totaling approximately $21.7 million.

<PAGE>   15

Included in accounts payable and accrued liabilities at September 30, 1999 is
approximately $1.3 million due to TIC. The amount represents a payable to TIC
for the reimbursement by TIC of development costs in excess of the amount
incurred by the Partnership, net of amounts owed to the Partnership for general
and administrative costs and other expenses incurred by the Partnership on
behalf of TIC.

In June 1999, TIC advanced the Partnership $46 million for the repayment of the
outstanding balance on the Partnership's unsecured line of credit. The advance
accrues interest at 4.87%. During the third quarter of 1999, an additional $25.7
million was advanced to the Partnership by TIC. In September 1999, the
Partnership repaid the total advance from TIC of $71.7 from the proceeds of the
$115 million loan. For the three and nine months ended September 30, 1999, the
Partnership incurred approximately $628,000 and $775,000 of interest costs
related to the advance.

Prior to the Merger, one of IAC, Inc.'s directors was president and chief
executive officer of a bank which participates in the Partnership's credit
facility and acts as trustee for the unsecured notes payable. Based on the
bank's percentage participation in the credit facility, the amount of interest
and fees paid to the bank totaled $93,000 and $122,000 for the three and six
months ended June 30, 1999, respectively, and $113,000 and $214,000 for the
three and nine months ended September 30, 1998, respectively.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

The following discussion compares the activities of the Partnership for the
three and nine month periods ended September 30, 1999 (unaudited) with the
activities of the Partnership for the three and nine month periods ended
September 30, 1998 (unaudited). The Trust is a limited purpose financing vehicle
established by the Partnership and exists for the sole purpose of issuing
preferred securities and investing the proceeds thereof in preferred limited
partnership units of the Partnership.

The following discussion should be read in conjunction with all the financial
statements appearing elsewhere in this report, as well as the information
presented in the Partnership's and the Trust's Annual Report on Form 10-K/A for
the year ended December 31, 1998.

Certain information set forth below is forward looking and involves various
risks and uncertainties. Such information is based upon a number of estimates
and assumptions that inherently are subject to business, economic and
competitive uncertainties and contingencies, many of which are beyond the
Partnership's control.

RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1998.

The Partnership's income after payment of minority redeemable preferred
interests was $18.1 million for the three months ended September 30, 1999, down
slightly from $18.5 million for the same period of 1998. The Partnership's
net income decreased slightly in 1999 due to the increase in minority redeemable
preferred interest resulting from the issuance of preferred securities in
November 1998. The decrease was offset, in part, by contributions of newly
delivered rental units from its development program, properties that stabilized
during 1999 and 1998 and an acquisition in 1998, as well as an increase in
rental rates within its stabilized portfolio and a slight increase in physical
occupancy.

(a) Represents "same store" communities.
(b) Represents three communities (768 units) that reached stabilized occupancy
    (95%) at different dates in 1998 and a 216-unit property acquired during
    1998.
(c) No year to year comparison is provided since the properties were not all
    stabilized for comparable periods.
(d) Represents two communities that started lease-up at different dates in 1998
    and two properties that started lease-up in 1999.


OPERATING REVENUES (rental and other income) increased by 13.7% to $64.1 million
in the third quarter of 1999, up from $56.4 million in the same period of 1998.
Operating revenues rose in 1999 because of higher rental rates and a larger
average number of rental units in service, primarily as a result of new
development. Newly delivered units, along with unit growth in the Partnership's
portfolio stabilized less than two years, added $9.4 million to operating
revenues from eight properties in the third quarter of 1999. Operating revenues
generated by communities stabilized more than two years increased 5.7% in 1999
due to an improvement in the portfolio's average rental rate and an increase in
average physical occupancy to 94.7% from 94.0%. The average monthly rental rate
for these communities increased 4.5% to $1,243 in the third quarter of 1999,
from $1,190 in the third quarter of 1998.

PROPERTY EXPENSES increased by 13.3% to $13.7 million in the third quarter of
1999, up from $12.1 million in the same period of 1998. The 1999 increase
reflects incremental expenses from newly delivered rental units and communities
stabilized during 1998. Property expenses for communities stabilized more than
two years increased slightly by $0.6 million to $11.8 million in the third
quarter of 1999. Average monthly property expenses generated by these
communities increased to $262 per unit in the third quarter of 1999 from $248
per unit in the third quarter of 1998. Newly delivered units and communities
stabilized less than two years added $1.9 million to property expenses from
eight properties in the third quarter of 1999. To improve operating efficiency
and reduce operating costs, the Partnership formed IAMC in April 1998 to manage
the Partnership's properties. The personnel and office



                                    Page 15

costs of IAMC are included in property expenses. For comparative purposes,
management fees prior to the formation of IAMC have been included in property
expenses.

REAL ESTATE TAXES totaled $5.0 million in the third quarter of 1999 and $4.5
million in the same period of 1998. Real estate taxes increased in the third
quarter of 1999 due primarily to the addition of new rental units.

NET INTEREST EXPENSE increased to $8.2 million in the third quarter of 1999
compared to $7.1 million in the same period of 1998. Total interest incurred was
$12.2 million in the third quarter of 1999 and $10.2 million in the same period
of 1998. Total interest incurred increased due to the impact of the
Partnership's unsecured term loan which was outstanding for the entire quarter
and the impact of the tax-exempt mortgage bonds outstanding during the quarter,
partially offset by decreased borrowings on the unsecured line of credit during
the quarter. Capitalized interest totaled $3.9 million in the third quarter of
1999 and $3.1 million in the same period of 1998. The increase in capitalized
interest in the third quarter of 1999 was due to the increase in the average
qualifying asset balance for projects under development. The Partnership
capitalizes interest on projects actively under development using qualifying
asset balances and applicable weighted average interest rates.

AMORTIZATION OF DEFERRED FINANCING COSTS was $0.5 million in the third quarter
of 1999 and 1998.

DEPRECIATION AND AMORTIZATION EXPENSE increased 43.6% to $12.3 million in the
third quarter of 1999, up from $8.6 million in the same period of 1998. The
increase primarily reflects the completion and delivery of newly developed
rental units.

GENERAL AND ADMINISTRATIVE EXPENSE increased to $2.7 million in the third
quarter of 1999, up from $2.2 million in the same period of 1998. The increase
in 1999 was the result of the increased salary expenses due to personnel changes
during the third quarter of 1999.

NINE MONTHS ENDED SEPTEMBER 30, 1999 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1998

The Partnership's income after payment of minority redeemable preferred
interests but before extraordinary item was $52.8 million for the nine months
ended September 30, 1999, up from $50.8 million for the same period of 1998. The
Partnership's net income improved in 1999 due to the contributions of newly
delivered rental units from its development program, properties that stabilized
during 1999 and 1998 and an acquisition in 1998, as well as an increase in
rental rates within its stabilized portfolio and a slight increase in physical
occupancy. These improvements were offset, in part, by an increase in minority
redeemable preferred interest due to the issuance of preferred securities in
January and November 1998 and an increase in general and administrative expenses
due to the payment of vested stock options in conjunction with the Merger.

OPERATING REVENUES (rental and other income) increased by 15.7% to $185.4
million in the first nine months of 1999, up from $160.2 million in the same
period of 1998. Operating revenues rose in 1999 because of higher rental rates
and a larger average number of rental units in service, primarily as a result of
new development. Newly delivered units, along with unit growth in the
Partnership's portfolio stabilized less than two years, added $24.9 million to
operating revenues from eight properties in the first nine months of 1999.
Operating revenues generated by communities stabilized more than two years
increased 5.9% in 1999 due to an improvement in the portfolio's average rental
rate and an increase in average physical occupancy to 94.4% from 93.9%. The
average monthly rental rate for these communities increased 4.9% to $1,231 in
the first nine months of 1999, from $1,173 in the first nine months of 1998.

PROPERTY EXPENSES increased by 9.6% to $39.5 million in the first nine months of
1999, up from $36.0 million in the same period of 1998. The 1999 increase
reflects incremental expenses from newly delivered rental units and communities
stabilized during 1998. Property expenses for communities stabilized more than
two years increased slightly by $0.3 million to $34.2 million in the first nine
months of 1999. Average monthly property expenses generated by these communities
increased to $254 per unit in the first nine months of 1999 from $251 per unit
in the first nine months of 1998. Newly delivered units and communities

personnel and office costs of IAMC are included in property expenses. For
comparative purposes, management fees prior to the formation of IAMC have been
included in property expenses.

REAL ESTATE TAXES totaled $14.3 million in the first nine months of 1999 and
$12.6 million in the same period of 1998. Real estate taxes increased in the
first nine months of 1999 due primarily to the addition of new rental units.

NET INTEREST EXPENSE increased to $22.4 million in the first nine months of 1999
compared to $20.5 million in the same period of 1998. Total interest incurred
was $34.8 million in the first nine months of 1999 and $29.4 million in the same
period of 1998. The increase in interest incurred in the first nine months of
1999 was primarily due to the unsecured term loan which was outstanding for the
entire period and the tax-exempt mortgage financings, a portion of which was
outstanding for the entire period. Capitalized interest totaled $12.3 million in
the first nine months of 1999 and $8.9 million in the same period of 1998. The
increase in capitalized interest in the first nine months of 1999 was due to the
increase in the average qualifying asset balance for projects under development.
The Partnership capitalizes interest on projects actively under development
using qualifying asset balances and applicable weighted average interest rates.

AMORTIZATION OF DEFERRED FINANCING COSTS was $1.4 million in the first nine
months of 1999 and 1998.

DEPRECIATION AND AMORTIZATION EXPENSE increased 27.2% to $31.7 million in the
first nine months of 1999, up from $24.9 million in the same period of 1998. The
increase primarily reflects the completion and delivery of newly developed
rental units.

GENERAL AND ADMINISTRATIVE EXPENSE increased to $11.6 million in the first nine
months of 1999, up from $6.6 million in the same period of 1998. The increase in
1999 was the result of payments of vested stock options in conjunction with the
Merger, increased salary expenses due to personnel changes and the write-off of
certain abandoned costs.

EXTRAORDINARY ITEM of $42.5 million in the first nine months of 1998 represents
charges associated with the Partnership's June 1998 debt refinancing
transaction. The charges consisted of the write-off of deferred financing costs,
prepayment costs and costs relating to the unwinding of certain swap agreements.

LIQUIDITY AND CAPITAL RESOURCES

The Partnership believes that cash provided by operations will be adequate to
meet both operating requirements and payment of distributions by the Partnership
to the preferred limited partners in both the short and long term.

LIQUIDITY: The Partnership expects to meet its short-term and long-term
liquidity requirements, such as construction costs and scheduled debt
maturities, through the refinancing of long-term debt or borrowings from
financial institutions. The Partnership's unsecured revolving credit facility
and $100 million unsecured term loan were amended in June 1999. The unsecured
revolving credit facility and unsecured term loan were amended and restated to
accommodate the Merger and to allow TIC and certain of its affiliates to
beneficially own and control all of the outstanding common partnership units in
the Partnership and IACLLC to become the sole general partner of the
Partnership. The Partnership's amended $125 million unsecured revolving credit
facility currently bears interest at LIBOR plus 0.65% or prime and matures in
June 2001. The interest rates under the credit facility are adjusted up or down
based on the credit ratings on the Partnership's senior unsecured long-term
indebtedness. Availability under the credit facility was $61.5 million at
September 30, 1999.



                                    Page 18
<PAGE>   21

SHELF REGISTRATION STATEMENTS: On May 14, 1997, the 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. On
October 1, 1997, the Partnership issued $100 million aggregate principal amount
of 7% senior unsecured notes pursuant to its shelf registration statement. In
June 1999, the Partnership cancelled the remaining availability of $250 million
under the shelf registration statement, including the Prospectus Supplement
dated April 9, 1998 filed for the future issuance of Medium-Term Notes. The
Partnership no longer plans to issue additional securities under the shelf
registration statement.

PREFERRED INTERESTS: In January 1998, the Trust issued 6.0 million 8 1/4% Series
A Preferred Securities. The proceeds of $150 million were used to purchase an
equivalent amount of 8 1/4% Series A Preferred Limited Partner Units in the
Partnership. The Partnership used the $150 million of proceeds, net of costs and
expenses, all of which where paid by the Partnership, to repay all outstanding
borrowings under the credit facility and to fund development and an acquisition.
In November 1998, the Partnership issued 2.0 million of 8 3/4% Series B
Preferred Limited Partner Units. The Partnership used the net proceeds to reduce
the outstanding balance on its unsecured line of credit.

DEBT: The Partnership's conventional debt bears interest at fixed interest
rates. Interest rates on conventional mortgage debt were reduced to then-current
market rates at the time of IAC, Inc.'s December 1993 initial public offering
through interest rate buy-down agreements that are scheduled to expire at
various dates prior to loan maturity that range from 2000 to 2008. The weighted
average effective interest rate on the Partnership's debt, including the
non-cash charges of amortization of deferred financing costs, was 6.19% at
September 30, 1999. In June 1998, the Partnership completed a $334 million
offering of unsecured tax-exempt debt at an average interest rate of 4.93% in
three tranches ranging from 10 to 15 years. Proceeds from the offering were used
to repay the Partnership's existing tax-exempt mortgage debt and to pay costs
associated with prepayment penalties and the unwinding of certain swap
agreements.

OPERATING ACTIVITIES: Cash provided by operating activities was $90.5 million
and $59.1 million in the first nine months of 1999 and 1998, respectively. Cash
provided by operating activities increased in the first nine months of 1999
compared to the same period in 1998 due to an extraordinary item related to debt
extinguishment in the first nine months of 1998, higher revenues from newly
developed and acquired apartment units, as well as an increase in revenues
within the Partnership's stabilized portfolio achieved through higher rental
rates and occupancy.

INVESTING ACTIVITIES: Cash used in investing activities was $118.8 million and
$179.7 million in the first nine months of 1999 and 1998, respectively. This
decrease reflects no acquisitions in the first nine months of 1999 as compared
to 1998.

FINANCING ACTIVITIES: Cash provided by financing activities was $97.0 million
and $121.9 million in the first nine months of 1999 and 1998, respectively. In
1998, the Partnership received net proceeds of $144 million from the issuance of
8 1/4% Series A Preferred Limited Partner Units and proceeds of $144 million
from its unsecured line of credit. The proceeds from the Series A Preferred
Securities were used to pay a portion of the outstanding borrowings under the
credit facility and for development. The Partnership received proceeds of $334.2
million from the issuance of tax-exempt bonds in June 1998. These proceeds were
used to repay existing tax-exempt mortgage bonds and to pay costs associated
with the offering. During 1999, the Partnership received advances from TIC
totaling $71.7 million. These proceeds were used to pay all outstanding
borrowings under the credit facility and for development. In September 1999, the
Partnership received proceeds of $6.6 million from the issuance of tax-exempt
mortgage bond financings and received proceeds of $115 million from a financial
institution. These proceeds were used to pay all outstanding advances from TIC
and also for development. The Partnership (and the Trust) made distributions of
$9.3 million to holders of the Trust's Series A Preferred Securities in the
first nine months of 1999 compared to $8.6 million in the first nine months of
1998. In addition, the Partnership made distributions of $3.3 million to holders
of the Partnership's Series B Preferred Limited Partner interests in the first
nine months of 1999.

CAPITAL EXPENDITURES

Capital expenditures consist of capital improvements and investments in real
estate assets. Capital improvements to operating real estate assets totaled $4.8
million and $3.6 million in the first nine months of 1999 and 1998,
respectively. Capital investments in real estate assets totaled $114.0 million
and $176.1 million in the first nine months of 1999 and 1998, respectively.
These investments consisted of new development and nonrecurring capital
replacements.

RECURRING CAPITAL IMPROVEMENTS WITHIN COMMUNITIES STABILIZED BEFORE 1998:
Expenditures for recurring capital improvements within communities stabilized
before 1998 totaled $4.7 million and $3.6 million in the first nine months of
1999 and 1998, respectively. Average recurring capital improvements per unit
were $312 and $238 in the first nine months of 1999 and 1998, respectively.
Expenditures for recurring capital improvements for the full year 1999 are
expected to be similar to full year 1998 levels. The Partnership has a policy of
capitalizing expenditures related to new assets, acquisitions, the material
enhancement of the value of an existing asset, or the substantial extension of
an existing asset's useful life.

RECURRING CAPITAL IMPROVEMENTS WITHIN COMMUNITIES STABILIZED IN OR AFTER 1998:
Expenditures for recurring capital improvements within communities stabilized in
or after 1998 totaled $120,000 for the first nine months of 1999. Expenditures
for recurring capital improvements are expected to be $144,000 for the full year
1999.

NONRECURRING CAPITAL REPLACEMENTS: Nonrecurring capital replacements consist of
special programs to upgrade and enhance a community to achieve higher rental
rates. Expenditures for nonrecurring capital replacements totaled $4.4 million
in the first nine months of 1999. These expenditures were made at six
properties. Costs to complete the special programs at the six properties are
expected to be approximately $6.9 million which will be spent over the next two
years.

CAPITAL INVESTMENTS IN NEW DEVELOPMENT: Currently, the Partnership has seven
apartment communities under development or construction that will require total
expenditures of approximately $546 million, of which $256 million had been
incurred as of September 30, 1999. Funding for these developments is expected to
come from borrowings from financial institutions, including the Partnership's
$125 million unsecured revolving credit facility (of which $61.5 million was
available as of September 30, 1999), and refinancing of long-term debt. The
Partnership has no plans for future development beyond the seven apartment
communities currently under development.

The timing of future commencement and completion of construction, the
commencement of leasing activity 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 Partnership. These include the extent and timing of economic
growth in the Partnership's rental markets; future trends in the pricing of
construction materials and labor; product design changes; entitlement decisions
by local government authorities; weather patterns; 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.

IRVINE RANCH MASTER PLAN

The Irvine Company is a real estate investment and community development firm
engaged in the long-term development of the Irvine Ranch. 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 which 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 entitlement 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 5,000-acre
research, technology and employment center which houses more than 2,200
companies and approximately 44,000 employees and includes 25 million square feet
of research and development and office 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 4.5
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 17,700 students and 6,200 employees. The
proximity of the Irvine Ranch properties to these employment centers makes them
attractive residential locations.

YEAR 2000 PROJECT

GENERAL: As is the case with many computer and microprocessor-based systems,
certain of the Partnership's systems use two digit date fields which recognize
dates using the assumption that the first two digits are "19" (i.e., the number
"99" is recognized as the year "1999"). Because of the nature of its operations,
the Partnership does not believe that its business, results of operations or
financial condition will be materially adversely affected by a failure of these



                                    Page 22
<PAGE>   25

systems. Nonetheless, the Partnership has initiated a plan to assess (and
remediate, as necessary) its computer and microprocessor-based systems.

STATE OF YEAR 2000 READINESS: The Partnership's Year 2000 project is divided
into four general exposure types--infrastructure and hardware, applications
software, third-party suppliers and customers ("third parties"), and process
control and instrumentation ("PC&I"). The general resolution phases common to
all sections are: (1) compiling potential Year 2000-sensitive items; (2)
assigning priorities to identified items; (3) assessing the Year 2000 compliance
of items determined to be material to the Partnership; (4) repairing or
replacing material items that are determined not to be Year 2000 compliant; and
(5) testing material items.

The completion percentages of the general resolution phases are based on the
level of effort expended to date versus the level of effort estimated to be
necessary to complete the task.

The infrastructure section consists of the routers, hubs, switches and related
components necessary to maintain communication with our properties, remote
offices and business partners. It also consists of all the hardware elements of
our file and application servers and personal computers. As of September 30,
1999, 100% of all infrastructure systems were believed to be Year 2000
compliant. By October 1999, 100% of all hardware systems were evaluated to be
Year 2000 compliant. The Partnership will conduct additional testing in November
of 1999.

The application section is broken into two types of applications, off-the-shelf
packages and custom-written software. By October 1999, 100% of all off-the-shelf
software had been upgraded to the latest Year 2000 compliant versions with the
exception of one application that will be replaced with a Year 2000 compliant
version during the fourth quarter of 1999. The custom-written applications are
also believed to be 100% Year 2000 compliant. The server applications will be
tested in the middle of the fourth quarter of 1999 to confirm their Year 2000
readiness. As of September 30, 1999, the Partnership had completed the testing
of its desktop computers and had made the necessary repairs and replacements on
60% of such desktop computers. The remaining 40% will be completed in November
of 1999.

The third parties section consists of identifying and prioritizing critical
suppliers and communicating with them about their plans and progress in
addressing the Year 2000 issue. The state of readiness of the Partnership's
third parties is based primarily on representations from such parties. The
Partnership has queried 100% of its significant suppliers and subcontractors
that do not share information systems with the Partnership. The Partnership has
received written Year 2000 status letters from all of the significant suppliers
and subcontractors queried. Of the significant suppliers and subcontractors
queried, 100% had a plan to remediate any Year 2000 issues and 100% had begun
assessing their systems, however, the completion percentages of their plans have
not been determined. Follow-up inquiries are scheduled through the remainder of
1999, at which time the Partnership will implement contingency plans or other
alternatives, as necessary, depending on the third parties' Year 2000 readiness.
To date, the Partnership is not aware of any third parties with a Year 2000
issue that would materially impact the Partnership's results of operations,
liquidity, or capital resources. However, the Partnership has no means of
ensuring that third parties will be Year 2000 ready.

The PC&I section includes the hardware, software and associated embedded chips
that are used in the operation of all facilities operated by the Partnership.
PC&I equipment includes security systems, lighting systems, HVAC systems and
sprinkler systems. As of October 1999, the Partnership had assessed all the
equipment at all the properties and determined the equipment to be 100% Year
2000 compliant. The Partnership will conduct additional testing in November of
1999.

COSTS: The Partnership has incurred less than $50,000 in connection with its
Year 2000 remediation efforts. The Partnership estimates its future costs
related to its Year 2000 remediation efforts to be less than $100,000. Overall,



                                    Page 23
<PAGE>   26

the Partnership does not expect its Year 2000 expenditures to be material to the
Partnership's business, results of operations or financial condition.

RISK AND CONTINGENCY PLANNING: Management of the Partnership believes it has a
program in place to adequately resolve the Year 2000 issue in a timely manner.
As noted above, the Partnership has not yet completed all necessary resolution
phases of the Year 2000 project. In the event that the Partnership does not
complete any additional phases related to its infrastructure, applications
software or PC&I, the Partnership does not believe that there will be a material
adverse effect on its business, results of operations or financial condition. A
Year 2000 failure by an important third party could materially disrupt the
Partnership's operations. For example, a Year 2000 failure by one or more of the
financial institutions or utility companies with which the Partnership does
business could cause the Partnership to lose access to its funds or could
restrict the Partnership's ability to borrow or operate a property. A Year 2000
failure by a trustee or transfer agent or by The Depository Trust Company could
restrict the Partnership's ability to pay interest on its bonds or to pay
dividends or distributions on its preferred securities. In addition, disruption
in the economy generally resulting from Year 2000 issues could also materially
adversely affect the Partnership. The Partnership could be subject to litigation
relating to the adverse effects resulting from the Year 2000 issue. The amount
of potential liability and lost revenue cannot be reasonably estimated at this
time. In the event the Partnership does not complete all resolution phases of
the Year 2000 project, the Partnership has created manual procedures as a
contingency plan until a resolution can be established.

The Partnership's assessment of its risks, and its expectations as to future
Year 2000 compliance, are forward-looking statements.

IMPACT OF INFLATION

The Partnership's business is affected by general economic conditions, including
the impact of inflation and interest rates. Substantially all of the
Partnership's leases allow, at time of renewal, for adjustments in the rent
payable thereunder, and thus may enable the 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
Partnership of the adverse effects of inflation. For construction, the
Partnership enters into various contracts for the development and construction
of new apartment communities. These are fixed-fee contracts and thus partially
insulate the Partnership from inflationary risk.

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



                                       21


<PAGE>   27

such loan. Such Election Notice shall contain the amount of the additional
Capital Contribution or the loan participation, if any, the Original Limited
Partner is to make (such additional Capital Contribution not to exceed the
respective Pro Rata Contribution of such Original Limited Partner and such loan
participation not to exceed the respective Pro Rata Participation of such
Original Limited Partner) equal to all or any portion of its Pro Rata
Contribution or Pro Rata Participation. No Original Limited Partner shall have
any participation right under this Section 4.5.G in connection with the
Partnership raising Additional Funds through the issuance of Preferred Limited
Partner Interest to IAC Capital Trust unless such Preferred Limited Partner
Interests are convertible into, or exercisable or exchangeable for, Common
Limited Partner Interests and as a result no Funding Notice need be given to the
Original Limited Partners in connection therewith.

         H. Percentage Interest Adjustments.

            (1) Upon the acceptance of additional cash Capital Contributions
pursuant to this Section 4.5, the Percentage Interests of the Partners shall be
adjusted based upon the number of Partnership Units issued in connection with
such Capital Contribution. Solely for purposes of calculating the number of
Partnership Units to be issued to the IAC Capital Trust in connection with a
contribution to the Partnership of the net proceeds from an offering of shares
of capital stock of the IAC Capital Trust, such cash Capital Contributions will
be deemed to equal the cash contributed by the IAC Capital Trust plus the
Offering Costs attributable to the cash contributed to the Partnership.

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

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

         I. Pledge of Additional Units. Notwithstanding anything contained
herein to the contrary, for so long as any Obligations (as defined in the Loan

                                  DISTRIBUTIONS

Section 5.1. Requirements and Characterization of Distributions. The General
Partner shall cause the Partnership to distribute quarterly all, or such portion
as the General Partner may in its discretion determine, including, but not

to the Partners who are Partners on the applicable Partnership Record Date with
respect to such quarter in the following order of priority:

                  (i) First, to the Preferred Limited Partners in such amount as

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

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



                                       23
<PAGE>   29

Subject to the prior rights of holders of Preferred Limited Partner Units with
respect to distributions of Available Cash, the General Partner in its sole
discretion may distribute to the General Partner and the Common Limited Partners
Available Cash (excluding amounts previously distributed to Preferred Limited
Partners as provided above) in accordance with their Junior Percentage Interests
on a more or less frequent basis and provide for an appropriate record date.

         Notwithstanding anything to the contrary contained herein, in no event
shall any Partner receive a distribution of Available Cash in respect of Junior
Partnership Interests with respect to any quarter or other period until such
time as the Partnership has distributed to the Preferred Limited Partners an
amount sufficient to pay all distributions payable with respect to the Preferred
Limited Partner Interests held by such Preferred Limited Partners in accordance
with the Designation Instrument or Instruments through the last day of the most
recently ended quarterly period set forth in each such Designation Instrument.

Section 5.2. Distributions in Kind. No right is given to any Partner to demand
and receive property other than cash. The General Partner may determine, in its
sole discretion but subject to the rights of Preferred Limited Partner
Interests, to make a distribution in kind to the General Partner and the Common
Limited Partners of Partnership assets, and such assets shall be distributed in
such a fashion as to ensure that the fair market value is distributed and
allocated in accordance with Articles 5, 6 and 10 hereof.

Section 5.3. Distributions Upon Liquidation. Proceeds from a Terminating Capital
Transaction, and any other cash received or reductions in reserves made after
commencement of the liquidation of the Partnership, shall be distributed to the

Section 5.4. Restricted Distributions. Notwithstanding any provision to the
contrary contained herein, the Partnership, and the General Partner on behalf of
the Partnership, shall not make a distribution to any Partner on account of its
interest in the Partnership if such distribution would violate Section 17-607 of
the Act or other applicable law.

Section 5.5. No Material Alterations. For so long as any Obligations (as defined
in the Loan Agreement) remain outstanding under the Loan Agreement, the
Partnership, and the General Partner on behalf of the Partnership, shall not
amend, modify or revise the provisions of this Article 5 concerning
distributions to the Common Limited Partners in any manner materially adverse to
the Banks without, in each such instance, first obtaining the written consent of
Agent, which may be granted, denied or conditioned in Agent's sole and absolute
discretion. This Section 5.5 is intended to be for the sole benefit of Agent and
the Banks.

                                   ALLOCATIONS

Section 6.1. Allocations in General. Except as otherwise provided in this
Article 6, and subject to Section 11.6.C, Net Income and Net Loss will be
allocated to each of the Partners at



                                       24
<PAGE>   30

the end of each calendar month using the interim closing of the books method and
taking into account varying interests in accordance with the greater part of the
month convention consistent with Section 11.6.C.

Section 6.2. Additional Allocation Provisions

         A. Special Allocations

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

         B. Regulatory Allocations

         Notwithstanding the foregoing provisions of this Article 6:

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

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




                                       25
<PAGE>   31

Minimum Gain attributable to such Partner Nonrecourse Debt, determined in
accordance with Regulations Section 1.704-2(i)(4). Allocations pursuant to the
previous sentence shall be made in proportion to the respective amounts required
to be allocated to each Partner pursuant thereto. The items to be so allocated
shall be determined in accordance with Regulations Section 1.704-2(i)(4) and
1.704-2(j)(2). This Section 6.2.B(2) is intended to qualify as a "chargeback of
partner nonrecourse debt minimum gain" within the meaning of Regulation Section
1.704-2(i) and shall be interpreted consistently therewith.

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

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

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

            (6) Limitation on Allocation of Net Loss. To the extent any
allocation of Net Loss would cause or increase an Adjusted Capital Account
Deficit as to any Partner, such allocation of Net Loss shall be reallocated
among the other Partners in accordance with their respective Partnership
Interests, subject to the limitations of this Section 6.2.B(6).

            (7) Section 754 Adjustment. To the extent an adjustment to the
adjusted tax basis of any Partnership asset pursuant to Code Section 734(b) or
Code Section 743(b) is



                                       26
<PAGE>   32

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

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

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

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

         E. Special Allocation in Year of Terminating Capital Transaction.
Notwithstanding Section 6.1, but subject to the other provisions of this Article
6, Net Income (or if necessary, items of Partnership gross income) arising in
the year of a Terminating Capital Transaction shall be specially allocated to
the IAC Capital Trust in an amount equal to the Offering Costs, to the extent
the IAC Capital Trust's Capital Account has not previously been adjusted to
account for such amounts.

Section 6.3. Tax Allocations

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



                                       27
<PAGE>   33

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


                                   ARTICLE 7.

the General Partner may owe the Partnership or the Limited Partners or any other
Persons under this Agreement or of any duty stated or implied by law or equity.

         C. At all times from and after the Prior Agreement Effective Date, the

amounts as the General Partner, in its sole discretion, deems appropriate and
reasonable from time to time.

         E. In exercising its authority under this Agreement, the General
Partner may, but shall be under no obligation to, take into account the tax
consequences to any Partner of any action taken by it. Except as otherwise
provided in the Declaration of Trust and Section 7.4.D hereof, the General
Partner and the Partnership shall not have liability to a Limited Partner under
any circumstances as a result of an income tax liability incurred by such
Limited Partner as a result of an action (or inaction) by the General Partner
pursuant to its authority under this Agreement so long as the action or inaction
is taken in good faith.

Section 7.2. Certificate of Limited Partnership. To the extent that such action
is determined by the General Partner to be reasonable and necessary or
appropriate, the General Partner shall file amendments to and restatements of
the Certificate and do all the things to maintain the Partnership as a limited
partnership (or a partnership in which the limited partners have limited
liability) under the laws of the State of Delaware and each other state or the
District of Columbia, in which the Partnership may elect to do business or own
property. Subject to the terms of Section 8.5(4) hereof, the General Partner
shall not be required, before or after filing, to deliver or mail a copy of the
Certificate or any amendment thereto to any Limited Partner. The General Partner
shall use all reasonable efforts to cause to be filed such other certificates or
documents as may be reasonable and necessary or appropriate for the formation,
continuation, qualification and operation of a limited partnership (or a
partnership in which the limited partners have limited liability to the extent
provided by applicable law) in the State of Delaware, the State of



                                       31
<PAGE>   37

California, and any other state, or the District of Columbia, in which the
Partnership may elect to do business or own property.

provided in this Agreement;

            (3) admit a Person as a Partner, except as otherwise provided in

            (4) perform any act that would subject a Limited Partner to

as provided herein or under the Act.

         B. The General Partner shall not, without the prior Consent of the
Common Limited Partners, undertake any of the following actions or enter into

Partners in accordance with this Agreement, and to amend Exhibit A to the
Agreement in connection with such admission, substitution or withdrawal;

            (3) to reflect a change that is of an inconsequential nature and
does not adversely affect the Limited Partners in any material respect, or to
cure any ambiguity, correct or supplement any provision in this Agreement not
inconsistent with law or with other provisions, or make other changes with
respect to matters arising under this Agreement that will not be inconsistent
with law or with the provisions of this Agreement;

            (4) to satisfy any requirements, conditions, or guidelines contained
in any order, directive, opinion, ruling or regulation of a federal or state
agency or contained in federal or state law;

            (5) to reflect such changes as are reasonably necessary for IAC

            (7) to set forth in a Designation Instrument the rights, powers and
duties of holders of Preferred Limited Partnership Interests issued pursuant to

shall not be amended, and no action may be taken by the General Partner, without
the Consent of each Common Limited Partner adversely affected and each Preferred
Limited Partner materially and adversely affected in each case if such amendment

General Partner Interest (except as a result of the General Partner acquiring
such interest), (ii) modify the limited liability of a Limited Partner, (iii)
alter rights of the Partner to receive distributions pursuant to Article 5,

Interests as shall be set forth in the applicable Designation Instrument or
Instruments, (2) only the Consent of Common Limited Partners shall be required
under clause (iv) above, and (3) with respect to clause (v) above, the Consent

                                       33
<PAGE>   39

Section 7.3.D materially and adversely affects the rights, powers and duties of
the Preferred Limited Partner Interests. Further, no amendment may alter the
restrictions on the General Partner's authority set forth in this Section 7.3

Partners, undertake, on behalf of the Partnership, any of the following actions:

            (1) Agree to or consummate any merger, consolidation, reorganization

            (2) Sell or otherwise transfer all or substantially all of the

         F. [Reserved].

         G. Except as provided in Section 7.3.D or in a Designation Instrument

<PAGE>   40

         B. The General Partner shall be reimbursed on a monthly basis, or such
other basis as the General Partner may determine in its reasonable discretion,
for all of its expenses including, without limitation, (i) expenses relating to
the ownership of interests in and operation of, or for the benefit of, the
Partnership, (ii) compensation of its officers and employees, and (iii) director
fees and expenses, provided that, the amount of any reimbursement shall be
reduced by any interest earned by the General Partner with respect to bank
accounts or other instruments or accounts held by it on behalf of the
Partnership as permitted pursuant to Section 7.5 hereof. Such reimbursements
shall be in addition to any reimbursement of the General Partner as a result of
indemnification pursuant to Section 7.7 hereof. Notwithstanding anything
contained herein to the contrary, the General Partner shall not be reimbursed by
the Partnership for any transaction costs it may incur in connection with the
sale or transfer of its General Partner interest in the Partnership.

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

         D. To the extent not previously paid by the Partnership pursuant to the
Declaration of Trust, the General Partner shall be reimbursed on a monthly
basis, or such other basis as the General Partner may determine in its
reasonable discretion, for all amounts incurred by it and payable by the
Partnership pursuant to the Declaration of Trust. Such amounts shall include the
amount of any underwriting discounts and commissions and other issuance costs
incurred by the General Partner or IAC Capital Trust, as the case may be, in
connection with the issuance of preferred stock of the General Partner or
preferred securities of IAC Capital Trust, as long as the gross proceeds from
such offering are concurrently contributed to the Partnership in exchange for
Preferred Limited Partner Interests. Such amounts shall be treated as incurred
on behalf of the Partnership and as an expense of the Partnership.

Section 7.5. Outside Activities of the General PartnerThe General Partner may
engage in such activities outside its duties as general partner as it deems fit
in its absolute discretion.

Section 7.6. Contracts with Affiliates

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



                                       35
<PAGE>   41

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

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

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

         E. The General Partner on its own behalf and on behalf of the
Partnership may enter into and perform its and the Partnership's obligations
under the Declaration of Trust and take all actions permitted to be taken by it
thereunder and such additional actions as are incidental thereto and may acquire
and own securities of IAC Capital Trust.

Section 7.7. Indemnification

         A. To the fullest extent permitted by applicable law, the Partnership
shall indemnify each Indemnitee from and against any and all losses, claims,
damages, liabilities, joint or several, expenses (including, without limitation,
attorney's fees and other legal fees and expenses), judgments, fines,
settlements, and other amounts arising from any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or investigative,
that relate to the operations of the Partnership ("Actions") as set forth in
this Agreement in which such Indemnitee may be involved, or is threatened to be
involved, as a party or otherwise, provided that the Partnership shall not
indemnify an Indemnitee (i) for willful misconduct or a knowing violation of the
law, or (ii) for any transaction for which such Indemnitee received an improper
personal benefit in violation or breach of any provision of this Agreement.
Without limitation, the foregoing indemnity shall extend to any liability of any
Indemnitee, pursuant to a loan guaranty or otherwise, for any indebtedness of
the Partnership or any Subsidiary of the Partnership (including, without
limitation, any indebtedness which the Partnership or any Subsidiary of the
Partnership has assumed or taken subject to), and the General Partner is hereby
authorized and empowered, on behalf of the Partnership, to enter into one or
more indemnity agreements consistent with the provisions of this Section 7.7 in
favor of any Indemnitee having or potentially having liability for any such
indebtedness. It is the intention of this Section 7.7.A that the Partnership
indemnify each Indemnitee to the fullest extent permitted by law. The
termination of any proceeding by judgment, order or settlement does not create a
presumption that the Indemnitee did not meet the requisite standard of conduct
set forth in this Section 7.7.A. The termination of any proceeding by conviction
of an Indemnitee or upon a plea of nolo contendere or its equivalent by an
Indemnitee, or an entry of an order of probation against an Indemnitee



                                       36
<PAGE>   42

prior to judgment, does not create a presumption that such Indemnitee acted in a
manner contrary to that specified in this Section 7.7.A with respect to the
subject matter of such proceeding. Any indemnification pursuant to this Section
7.7 shall be made only out of the assets of the Partnership, and neither the
General Partner nor any Limited Partner shall have any obligation to contribute
to the capital of the Partnership or otherwise provide funds to enable the
Partnership to fund its obligations under this Section 7.7.

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

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

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

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

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



                                       37
<PAGE>   43

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

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

Section 7.8. Liability of the General Partner

         A. Notwithstanding anything to the contrary set forth in this
Agreement, neither the General Partner nor any of its officers or directors
shall be liable for monetary damages to the Partnership, any Partners or any
Assignees for losses sustained or liabilities incurred as a result of errors in
judgment or of any act or omission if the General Partner or such officer or
director acted in such cases in good faith.

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

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

         D. Notwithstanding anything herein to the contrary, except for fraud,
willful misconduct or gross negligence, or pursuant to any express indemnities
given to the Partnership by any Partner pursuant to any other written
instrument, no Partner shall have any personal liability whatsoever, to the
Partnership or to the other Partners, for the debts or liabilities of the
Partnership or the Partnership's obligations hereunder, and the full recourse of
the other Partners shall be limited to the interest of that Partner in the
Partnership. Without limitation of the foregoing, and except for fraud, willful
misconduct or gross negligence, or pursuant to any such express indemnity, no
property or assets of any Partner, other than its interest in the Partnership,
shall be subject to levy, execution or other enforcement procedures for the
satisfaction of any



                                       38
<PAGE>   44

judgment (or other judicial process) in favor of any other Partner(s) and
arising out of, or in connection with, this Agreement. This Agreement is
executed by the officers of the General Partner solely as officers of the same
and not in their own individual capacities.

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

         F. Whenever in this Agreement a Limited Partner is permitted or
required to make a decision (i) in its "sole discretion" or "discretion" or
under a grant of similar authority or latitude, the Limited Partner shall be
entitled to consider only such interests and factors as it desires, including
its own interests, and shall have no duty or obligation to give any
consideration to any interest of or factors affecting the Partnership or the
other Partners or (ii) in its "good faith" or under another express standard,
the Limited Partner shall act under such express standard and shall not be
subject to any other or different standards imposed by this Agreement or any
other agreement contemplated herein or by relevant provisions of law or in
equity or otherwise.

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

Section 7.9. Other Matters Concerning the General Partner

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

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

         C. The General Partner shall have the right, in respect of any of its
powers or obligations hereunder, to act through any duly appointed attorney or
attorneys-in-fact. Each such attorney shall, to the extent provided by the
General Partner in the power of attorney, have full



                                       39
<PAGE>   45

power and authority to do and perform all and every act and duty which is
permitted or required to be done by the General Partner hereunder.

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

Section 7.10. Title to Partnership Assets. Title to Partnership assets, whether
real, personal or mixed and whether tangible or intangible, shall be deemed to
be owned by the Partnership as an entity, and no Partner, individually or
collectively, shall have any ownership interest in such Partnership assets or
any portion thereof. Title to any or all of the Partnership assets may be held
in the name of the Partnership or one or more nominees, as the General Partner
may determine. The General Partner hereby declares and warrants that any
Partnership assets for which legal title is held in the name of the General
Partner or any nominee or Affiliate of the General Partner shall be held by the
General Partner for the use and benefit of the Partnership in accordance with
the provisions of this Agreement; provided, however, that the General Partner
shall use its best efforts to cause beneficial and record title to such assets
to be vested in the Partnership as soon as reasonably practicable. All
Partnership assets shall be recorded as the property of the Partnership in its
books and records, irrespective of the name in which legal title to such
Partnership assets is held.

Section 7.11. Reliance by Third Parties. Notwithstanding anything to the
contrary in this Agreement, any Person dealing with the Partnership shall be
entitled to assume that the General Partner has full power and authority,
without the consent or approval of any other Partner or Person, to encumber,
sell or otherwise use in any manner any and all assets of the Partnership and to
enter into any contracts on behalf of the Partnership, and take any and all
actions on behalf of the Partnership, and such Person shall be entitled to deal
with the General Partner as if the General Partner were the Partnership's sole
party in interest, both legally and beneficially. Each Limited Partner hereby
waives any and all defenses or other remedies which may be available against
such Person to contest, negate or disaffirm any action of the General Partner in
connection with any such dealing. In no event shall any Person dealing with the
General Partner or its representatives be obligated to ascertain that the terms
of this Agreement have been complied with or to inquire into the necessity or
expedience of any act or action of the General Partner or its representatives.
Each and every certificate, document or other instrument executed on behalf of
the Partnership by the General Partner or its representatives shall be
conclusive evidence in favor of any and every Person relying thereon or claiming
thereunder that (i) at the time of the execution and delivery of such
certificate, document or instrument, this Agreement was in full force and
effect, (ii) the Person executing and delivering such certificate, document or
instrument was duly authorized and empowered to do so for and on behalf of the
Partnership and (iii) such certificate, document or instrument was duly executed
and delivered in accordance with the terms and provisions of this Agreement and
is binding upon the Partnership.

their Affiliates, in their capacity as such) shall take part in the operation,
management or control of the Partnership's business, transact any business in
the Partnership's name or have the power to sign documents for or otherwise bind
the Partnership. The transaction of any such business by the General Partner,
any of its Affiliates or any officer, director, employee, partner, agent or
trustee of the General Partner, the Partnership or any of their Affiliates, in
their capacity as such, shall not affect, impair or eliminate the limitations on

entered into pursuant to Section 7.6.D hereof and any other agreements entered
into by a Limited Partner or its Affiliates with the General Partner, the

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

distributions. Preferred Limited Partner Units of a series shall be redeemed
only in accordance with a Designation Instrument relating thereto.

Section 8.5. Rights of Limited Partners Relating to the Partnership

         In addition to other rights provided by this Agreement or by the Act,
each Limited Partner shall have the right, for a purpose reasonably related to

                                   ARTICLE 10.

                                   TAX MATTERS

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

Section 10.2. Tax Elections. Except as otherwise provided herein, the General
Partner shall, in its sole discretion, determine whether to make any available
election pursuant to the Code. The General Partner shall make the election under
Section 754 of the Code in accordance with applicable Regulations thereunder.
The General Partner shall elect, and shall file such returns and amended
returns, as necessary, in a manner consistent with the use of the recurring item
method of accounting provided under Section 461(h) of the Code with respect to
property taxes imposed on the Property of the Partnership, including causing the
applicable property taxes to be paid prior to the date provided under Section
461(h) for purposes of economic performance. The General Partner shall have the
right to seek to revoke any such election (excluding the elections under
Sections 461(h) and 754 of the Code) upon the General Partner's determination in
its sole discretion that such revocation is in the best interests of the
Partners.

Section 10.3. Tax Matters Partner. The General Partner shall be the "tax matters
partner" of the Partnership for federal income tax purposes. The tax matters
partner shall receive no compensation for its services. All third party costs
and expenses incurred by the tax matters partner in performing its duties as
such (including legal and accounting fees and expenses) shall be borne by the
Partnership in addition to any reimbursement pursuant to Section 7.4 hereof.
Nothing herein shall be construed to restrict the Partnership from engaging an
accounting firm to



                                       43
<PAGE>   49

assist the tax matters partner in discharging its duties hereunder, so long as
the compensation paid by the Partnership for such services is reasonable. At the
request of any Limited Partner, the General Partner agrees to consult with such
Limited Partner with respect to the preparation and filing of any returns,
including, without limitation any subsequent audit or litigation with respect to
such return, provided the filing of such returns shall be in the sole discretion
of the General Partner, provided, however, that the Original Limited Partners
shall have the right, at their own expense, to contest any adjustment and
approve any settlement in connection with an item that was allocated to them
pursuant to Section 6.2.A.

Section 10.4. Withholding. Each Limited Partner hereby authorizes the
Partnership to withhold from or pay on behalf of or with respect to such Limited
Partner any amount of federal, state, local, or foreign taxes that the General
Partner determines that the Partnership is required to withhold or pay with
respect to any amount distributable or allocable to such Limited Partner
pursuant to this Agreement, including without limitation any taxes required to
be withheld or paid by the Partnership pursuant to Section 1441, 1442, 1445 or
1446 of the Code. Any amount paid on behalf of or with respect to a Limited
Partner shall constitute a loan by the Partnership to such Limited Partner,
which loan shall be repaid by such Limited Partner within fifteen (15) days
after notice from the General Partner that such payment must be made unless (i)
the Partnership withholds such payment from a distribution which would otherwise
be made to the Limited Partner or (ii) the General Partner determines that such
payment may be satisfied out of the available funds of the Partnership which
would, but for such payment, be distributed to the Limited Partner. Any amounts
withheld pursuant to the foregoing clauses (i) or (ii) shall be treated as
having been distributed to such Limited Partner pursuant to Article 5 hereof.


                                   ARTICLE 11.

              TRANSFERS AND WITHDRAWALS; REMOVAL OF GENERAL PARTNER

Section 11.1. Transfer

         A. The term "Transfer," when used in this Article 11 with respect to a
Partnership Unit, shall be deemed to refer to a transaction by which the General
Partner purports to assign all or any part of its General Partner Interest to
another Person or by which a Limited Partner purports to assign all or any part
of its Limited Partner Interest to another Person.

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

Section 11.2. Transfer of General Partner's Interest

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



                                       44
<PAGE>   50

         B. The General Partner shall not withdraw from the Partnership and
shall not Transfer, pledge, encumber or otherwise dispose of all or any portion
of its interest in the Partnership (whether by sale, disposition, statutory
merger or consolidation, liquidation or otherwise) without the Consent of the
Common Limited Partners. Upon any Transfer of such a Partnership Interest
pursuant to the Consent of the Common Limited Partners and otherwise in
accordance with the provisions of this Section 11.2.B, the transferee shall
become a successor General Partner for all purposes herein, and shall be vested
with the powers and rights of the transferor General Partner, and shall be
liable for all obligations and responsible for all duties of the General
Partner, once such transferee has executed such instruments as may be necessary
to effectuate such admission and to confirm the agreement of such transferee to
be bound by all the terms and provisions of this Agreement with respect to the
Partnership Interest so acquired. It is a condition to any such Transfer that
the transferee assumes, by operation of law or express agreement, all of the
obligations of the transferor General Partner under this Agreement with respect
to such transferred Partnership Interest, and no such Transfer (other than
pursuant to a statutory merger or consolidation wherein all obligations and
liabilities of the transferor General Partner are assumed by a successor
corporation by operation of law) shall relieve the transferor General Partner of
its obligations under this Agreement without the Consent of the Common Limited
Partners.

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

Section 11.3. Limited Partners' Rights to Transfer

         A. A Limited Partner shall have the right to transfer all or any
portion of its Partnership Interest to any Person, subject to the provisions of
Section 11.6 hereof and, in the case of Preferred Limited Partner Interests
owned by IAC Capital Trust, 11.3.E hereof; provided that, any Transfer of a
Partnership Interest shall be made only to a Qualified Transferee.
Notwithstanding the foregoing provisions of this Section 11.3, any Original
Limited Partner may, at any time, without the consent of the General Partner,
(i) Transfer all or any portion of its Partnership Interest to an Affiliate or
to an Irvine Person, subject to the provisions of Section 11.6 hereof and (ii)
Pledge any portion of its Partnership Interest. It is a condition to any
Transfer otherwise permitted hereunder that the transferee assumes by operation
of law or express agreement all of the obligations of the transferor Limited
Partner under this Agreement with respect to such transferred Partnership
Interest and no such Transfer (other than pursuant to a statutory merger or
consolidation wherein all obligations and liabilities of the transferor Limited
Partner are assumed by a successor corporation by operation of law) shall
relieve the transferor Limited Partner of its obligations under this Agreement
without the approval of the General Partner, in its sole discretion. Any
transferee shall take subject to the obligations of the transferor hereunder,
but such transferee shall not be liable for the obligations of the transferor
under Section 17-607 of the Act. Until admitted as a Substituted Limited
Partner, no transferee, whether by a voluntary transfer, by operation of law or
otherwise, shall have any rights hereunder, other than the rights of an Assignee
as provided in Section 11.5 hereof.



                                       45
<PAGE>   51

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

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

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

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

         F. [Reserved].

         G. [Reserved].

Section 11.4. Substituted Limited Partners

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


                                       46
<PAGE>   52

Partner shall promptly admit such transferee of the interest of a Limited
Partner as a Substituted Limited Partner.

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

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

Section 11.5. Assignees. Until such time as a transferee has been admitted as a
Substituted Limited Partner pursuant to Section 11.4, such transferee shall be
considered an Assignee for purposes of this Agreement. An Assignee shall be
deemed to have had assigned to it, and shall be entitled to receive,
distributions from the Partnership and the share of Net Income, Net Losses, and
any other items of income, gain, loss, deduction and credit of the Partnership
attributable to the Limited Partner Units assigned to such transferee, but shall
not be deemed to be a holder of Limited Partner Units for any other purpose
under this Agreement, and shall not be entitled to vote such Limited Partner
Units in any matter presented to the Limited Partners of the same class or
series for a vote (such Limited Partner Units being deemed to have been voted on
such matter in the same proportion as all other Limited Partner Units held by
Limited Partners of the same class or series are voted). In the event any such
transferee desires to make a further assignment of any such Partnership Units,
such transferee shall be subject to all the provisions of this Article 11 to the
same extent and in the same manner as any Limited Partner desiring to make an
assignment of Limited Partner Units.

Section 11.6. General Provisions

         A. No Limited Partner may withdraw from the Partnership other than as a
result of a permitted Transfer of all of such Limited Partner's Limited Partner
Units in accordance with this Article 11.

         B. Any Limited Partner who shall Transfer all of his Limited Partner
Units in a transfer permitted pursuant to this Article 11 shall cease to be a
Limited Partner upon the admission of all Assignees of such Limited Partner
Units as Substituted Limited Partners. Similarly, any Preferred Limited Partner
whose Preferred Limited Partner Units of a series are redeemed in full or paid
in full upon the stated maturity thereof, in each case, in accordance with the
Designation Instrument applicable to such series of Partnership Units shall
cease to be a Preferred Limited Partner insofar as such series is concerned.

         C. If any Partnership Unit is Transferred during any quarterly segment
of the Partnership Year in compliance with the provisions of this Article 11,
then Net Income, Net Losses, each item thereof and all other items attributable
to such Partnership Unit for such Partnership Year shall be allocated to the
transferor Partner, and to the transferee Partner by taking into account their
varying interests during the Partnership Year in accordance with Section



                                       47
<PAGE>   53

706(d) of the Code, using the interim closing of the books method. Solely for
purposes of making such allocations, each of such items for the calendar month
in which a transfer occurs shall be allocated to the transferee Partner and none
of such items for the calendar month in which a transfer occurs shall be
allocated to the transferor Partner, if such transfer occurs before the
fifteenth day of the month, otherwise such items shall be allocated to the
transferor. All distributions of Available Cash attributable to such Partnership
Unit with respect to which the Partnership Record Date is before the date of
such transfer or assignment shall be made to the transferor Partner and all
distributions of Available Cash thereafter attributable to such Partnership Unit
shall be made to the transferee Partner.

         D. In addition to any other restriction on transfer herein contained,
in no event may any transfer or assignment of a Partnership Interest by any
Partner (including any acquisition of Partnership Units by the General Partner)
be made (i) to any person or entity who lacks the legal right, power or capacity
to own a Partnership Interest; (ii) in violation of applicable law; (iii) of any
component portion of a Partnership Interest, such as the Capital Account, or
rights to distributions, separate and apart from all other components of a
Partnership Interest, (iv) if such transfer would, in the opinion of counsel to
the Partnership, cause the Partnership to cease to be classified as a
partnership for Federal income tax purposes; (v) if such transfer would cause
the Partnership to become, with respect to any employee benefit plan subject to
Title I of ERISA, a "party-in-interest" (as defined in Section 3(14) of ERISA)
or a "disqualified person" (as defined in Section 4975(c) of the Code); (vi) if
such transfer would, in the opinion of counsel to the Partnership, cause any
portion of the assets of the Partnership to constitute assets of any employee
benefit plan pursuant to Department of Labor Regulations Section 2510.2-101;
(vii) if such transfer requires the registration of such Partnership Interest
pursuant to any applicable federal or state securities laws other than in
connection with the issuance of preferred securities of IAC Capital Trust;
(viii) if such transfer requires the Partnership to become a reporting company
under the Securities Exchange Act of 1934; or (ix) if such transfer subjects the
Partnership to be regulated under the Investment Company Act of 1940, the
Investment Advisors Act of 1940 or the Employee Retirement Income Security Act
of 1974, each as amended.

Section 11.7. Removal of General Partner

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

         B. Upon the removal of the General Partner, the departing General
Partner shall become a Common Limited Partner, and its General Partner Interest
shall be converted



                                       48
<PAGE>   54

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

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

         C. The successor to the departing General Partner shall at the
effective date of its admission to the Partnership contribute to the capital of
the Partnership cash in an amount such that its Capital Account, after giving
effect to such contribution, shall be at least equal to the amount, if any,
required by any applicable law.

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

                                   ARTICLE 12.

                              ADMISSION OF PARTNERS

Section 12.1. Admission of Successor General Partner. A successor to all of the
General Partner Interest pursuant to Section 11.2.B hereof who is proposed to be
admitted as a successor General Partner shall be admitted to the Partnership as
the General Partner, effective immediately prior to such Transfer. A successor
to a General Partner removed pursuant to Section 11.7 shall be admitted to the
Partnership as the successor General Partner effective upon satisfaction of the
condition specified in Section 11.7.C. Any such successor shall carry on the
business of the Partnership without dissolution. In each case, the admission
shall be subject to the successor General Partner executing and delivering to
the Partnership an acceptance of all of the terms and conditions of this
Agreement and such other documents or instruments as may be required to effect
the admission.

Section 12.2. Admission of Additional Limited Partners

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



                                       49
<PAGE>   55

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

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

Section 12.3. Amendment of Agreement and Certificate of Limited Partnership. For
the admission to the Partnership of any Partner, the General Partner shall take
all steps necessary and appropriate under the Act to amend the records of the
Partnership and, if necessary, to prepare as soon as practical an amendment of
this Agreement (including an amendment of Exhibit A) and, if required by law,
shall prepare and file an amendment to the Certificate and may for this purpose
exercise the power of attorney granted pursuant to Section 2.4 hereof.

Section 12.4. Limit on Number of Partners. No Person shall be admitted to the
Partnership as an additional Partner if the effect of such admission would be to
cause the Partnership to have more than 500 Partners, including as Partners for
this purpose those Persons indirectly owning an interest in the Partnership
through another partnership, subchapter S corporation or a grantor trust, or
otherwise cause the Partnership to become a reporting company under the
Securities Exchange Act of 1934, as amended.

                                   ARTICLE 13.

this Agreement. Upon the withdrawal or removal of the General Partner, any
successor General Partner shall continue the business of the Partnership without
dissolution. The Partnership shall dissolve, and its affairs shall be wound up,
upon the first to occur of any of the following ("Liquidating Events"):

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

withdrawal, of a successor General Partner; and (ii) more than fifty percent
(50%) of the aggregate Liquidation Preference Amount of all series of Preferred

successor General Partner;

         C. an election to dissolve the Partnership made by the General Partner,

the Partnership.

         Section 13.2. Winding Up

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

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

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



                                       51
<PAGE>   57

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

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

            (4) Fourth, to the Preferred Limited Partners, the applicable
Liquidation Preference Amount plus accrued and unpaid distributions in
accordance with the terms of the applicable Designation Instrument(s); and

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

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

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

         C. If any Partner has a deficit balance in his Capital Account (after
giving effect to all contributions, distributions and allocations for all
taxable years, including the year during which such liquidation occurs), such
Partner shall have no obligation to make any contribution to the capital of the
Partnership with respect to such deficit, and such deficit shall not be
considered a debt owed to the Partnership or to any other Person for any purpose
whatsoever. A pro rata portion of the distributions that would otherwise be made
to the General Partner and Limited Partners pursuant to this Article 13 may be
withheld or escrowed to provide a reasonable reserve for Partnership liabilities
(contingent or otherwise) and to reflect the unrealized portion of any
installment obligations owed to the Partnership, provided that such withheld or
escrowed



                                       52
<PAGE>   58

amounts shall be distributed to the General Partner and Limited Partners in the
manner and order of priority set forth in Section 13.2.A as soon as practicable.

Section 13.3. [Reserved].

Section 13.4. Rights of Limited Partners. Except as otherwise provided in this
Agreement, each Limited Partner shall look solely to the assets of the
Partnership for the return of his Capital Contributions and shall have no right
or power to demand or receive property other than cash from the Partnership.
Except as otherwise provided in this Agreement (including pursuant to any
Designation Instrument or Instruments), no Limited Partner shall have priority
over any other Partner as to the return of his Capital Contributions,
distributions, or allocations.

Section 13.5. Notice of Dissolution. In the event a Liquidating Event occurs or
an event occurs that would, but for an election or objection by one or more
Partners pursuant to Section 13.1, result in a dissolution of the Partnership,
the General Partner shall within thirty (30) days thereafter, provide written
notice thereof to each of the Partners.

Section 13.6. Termination of Partnership and Cancellation of Certificate of
Limited Partnership. Upon the completion of the liquidation of the Partnership
cash and property as provided in Section 13.2 hereof, the Partnership shall be
terminated, a certificate of cancellation shall be filed, and all qualifications
of the Partnership as a foreign limited partnership in jurisdictions other than
the State of Delaware shall be canceled and such other actions as may be
necessary to terminate the Partnership shall be taken.

Section 13.7. Reasonable Time for Winding-Up. A reasonable time shall be allowed
for the orderly winding-up of the business and affairs of the Partnership and
the liquidation of its assets pursuant to Section 13.2 hereof, in order to
minimize any losses otherwise attendant upon such winding-up, and the provisions
of this Agreement shall remain in effect between the Partners during the period
of liquidation.

Section 13.8. Waiver of Partition. Each Partner hereby waives any right to
partition of the Partnership property.

                  AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS

Section 14.1. Amendments. Subject to Section 14.3, Amendments to this Agreement
may be proposed by the General Partner or by a Majority-In-Interest of the
Common Limited Partners. Following such proposal, the General Partner shall
submit any proposed amendment to the Common Limited Partners. The General
Partner shall seek the written vote of the Common Limited Partners on the
proposed amendment or shall call a meeting to vote thereon and to transact any
other business that it may deem appropriate. For purposes of obtaining a written
vote, the General Partner may require a response within a reasonable specified
time, but not less than fifteen (15) days, and failure to respond in such time
period shall constitute a vote which is consistent with the General Partner's
recommendation with respect to the proposal. Except as



                                       53
<PAGE>   59

provided in Section 7.3.B, 7.3.C or 7.3.D hereof, a proposed amendment shall be
adopted and be effective as an amendment hereto if it is approved by the General
Partner and it receives the Consent of Common Limited Partners.

Section 14.2. Meetings of the Common Limited Partners

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

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

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

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

Section 14.3. Meetings of Preferred Limited Partners. In the event that the vote
or consent of the holders of Preferred Limited Partner Interests (or any series
thereof) is required pursuant to this Agreement (including pursuant to a
Designation Instrument) such vote or consent may be obtained at a meeting of
Preferred Limited Partners or by written consent. The provisions of



                                       54
<PAGE>   60

Section 14.2 hereof shall apply to any such meeting or written consent to the
extent practicable in which case all references in such Section to Common
Limited Partners shall mean the Preferred Limited Partners as a class or the
Preferred Limited Partners holding the applicable series of Preferred Limited
Partner Interests, as shall be applicable to such vote or consent.

                       LIMITATIONS OR RESTRICTIONS OF THE
                    SERIES A PREFERRED LIMITED PARTNER UNITS

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

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

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

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

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

                                       C-1

<PAGE>   72

Partnership acting through the General Partner out of funds legally available
for the payment of distributions, cumulative preferential cash distributions at
the rate per annum of 8 1/4% of the Stated Value. Distributions will be
cumulative, will accrue from January 20, 1998, the original issue date of the
Series A Preferred Limited Partner Units, 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 Payment Date is not
a Business Day, then payment of the distribution to be made on such Series A
Distribution Payment Date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay) except that if such Business Day is in the next succeeding calendar year,
such payment shall be made on the immediately preceding Business Day, in each
case with the same force and effect as if made on such Series A Distribution
Payment Date. Each such distribution will be payable to the holders of record of
the Series A Preferred Limited Partner Units as they appear on the books of the
Partnership or any transfer agent for the Series A Preferred Limited Partner
Units on such record dates selected by the General Partner, not less than 1O nor
more than 50 days preceding the applicable Series A Distribution Payment Date;
provided that so long as the Series A Preferred Limited Partner Units are owned
by IAC Capital Trust, the General Partner shall establish record dates with
respect to the Series A Preferred Limited Partner Units that shall coincide with
the record dates established with respect to the 8 1/4% Series A REIT Trust
Originated Preferred Securities of IAC Capital Trust (the "SERIES A PREFERRED
SECURITIES").

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

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

                                        2

<PAGE>   73

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

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

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

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

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

                                        4
<PAGE>   75

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

         (b) Except in the case of a Tax Event or Investment Company Act Event
(each as defined in Section 4(c) below), the Series A Preferred Limited Partner
Units may not be redeemed prior to December 31, 2002. On or after such date the
Partnership shall have the right to redeem the Series A Preferred Limited
Partner Units, in whole or in part, from time to time, upon notice as provided
in Section 4(d) below, at a redemption price equal to the Stated Value per
Series A Preferred Limited Partner Unit plus, subject to Section 5(g) hereof,
accumulated and unpaid distributions to the date of payment (the "SERIES A
REDEMPTION PRICE"), provided that the Partnership may not redeem fewer than all
the outstanding Series A Preferred Limited Partner Units unless all accumulated
and unpaid distributions have been paid on all Series A Preferred Limited
Partner Units for all quarterly distributions periods ending on or prior to the
date of redemption.

         (c) If, at any time prior to December 31, 2002, a Tax Event or
Investment Company Event (each, a "SPECIAL EVENT") shall occur and be
continuing, the Partnership shall have the right to redeem the Series A
Preferred Limited Partner Units in whole but not in part at the Series A
Redemption Price, provided, however, that, if at the time there is available to
the Partnership or IAC Capital Trust the opportunity to eliminate, within a
90-day period, the Special Event by taking some ministerial action
(collectively, "MINISTERIAL ACTIONS"), such as filing a form or making an
election, or pursuing some other similar reasonable measure, which in the sole
judgment of the General Partner has or will cause no adverse effect on IAC
Capital Trust, the Partnership, Irvine Apartment Communities or the holders of
the Series A Preferred Securities and will involve no material cost, the
Partnership and IAC Capital Trust will pursue such measure in lieu of such
redemption, provided further, that the Partnership shall have no right to redeem
the Series A Preferred Limited Partner Units while the Partnership or the
Regular Trustees (as defined in the Declaration of Trust) on behalf of IAC
Capital Trust are pursuing any such Ministerial Action. The Partnership shall
have the right, upon not less than 30 nor more than 60 days' notice, to redeem
the Series A Preferred Limited Partner Units in whole for cash at the Series A
Redemption Price as provided in Section 5(b) within 90 days following the
occurrence of such Special Event (subject to extension for the number of days
Ministerial Actions are pursued).

                                        5

<PAGE>   76

         "INVESTMENT COMPANY EVENT" means that the Partnership and the Regular
Trustees of IAC Capital Trust shall have received an opinion of nationally
recognized independent counsel experienced in practice under the Investment
Company Act of 1940, as amended (the "1940 ACT"), that as a result of the
occurrence of a change in law or regulation or a change in interpretation or
application of law or regulation by any legislative body, court, governmental
agency, or regulatory authority (a "CHANGE IN 1940 ACT LAW"), there is more than
an insubstantial risk that IAC Capital Trust is or will be considered an
"investment company" which is required to be registered under the 1940 Act,
which Change in 1940 Act Law becomes effective on or after January 14, 1998.

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

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

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

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

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

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

                                        6
<PAGE>   77

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

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

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

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

                                        7

<PAGE>   78

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

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

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

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

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

                                       8

<PAGE>   79

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

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

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

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

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

         (c) In the event the Partnership or any of its subsidiaries purchases
outstanding Series A Preferred Securities by tender, in the open market or by
private agreement in accordance with the terms thereof, the Partnership may

                                        9

<PAGE>   80

deliver, or cause to be delivered, to the Property Trustee (as defined in the
Declaration of Trust) for cancellation the Series A Preferred Securities so
purchased and, if so delivered, the Property Trustee as the registered owner of
the series of Preferred Limited Partner Units with substantially similar
economic terms shall promptly deliver to the Partnership for cancellation an
equal number of such series of Preferred Limited Partner Units and such
Preferred Limited Partner Units so cancelled shall no longer be deemed
outstanding. In such event, the Partnership shall deliver to the Property
Trustee a new certificate for the Preferred Limited Partner Units of such series
which remain outstanding.

                       LIMITATIONS OR RESTRICTIONS OF THE
                    SERIES B PREFERRED LIMITED PARTNER UNITS

     FIRST: Pursuant to authority expressly vested in the General Partner of the
Partnership pursuant to Section 4.5.F of the Partnership Agreement, the General
Partner hereby classifies 2,000,000 Preferred Limited Partner Interests of the
Partnership into a series designated the Series B Preferred Limited Partner
Units and provides for the issuance of such Series B Preferred Limited Partner
Units. This instrument constitutes a Designation Instrument under the
Partnership Agreement. Capitalized terms used but not defined herein have the
meanings set forth in the Partnership Agreement.

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

     SECTION 1. Designation and Amount. The series of Preferred Limited Partner
Interests shall be designated the "Series B Preferred Limited Partner Units" and
the authorized number of Partnership Units constituting such series shall be
2,000,000.

     SECTION 2. Stated Value. The stated value of the Series B Preferred Limited
Partner Units shall be $25.00 per unit (the "Stated Value").

     SECTION 3. Distributions. (a) Subject to the rights of holders of any
series of Preferred Limited Partner Units which the Partnership may issue in the
future

                                       D-1
<PAGE>   85

which rank on a parity with the Series B Preferred Limited Partner Units in
respect of distributions, the holders of outstanding Series B Preferred Limited
Partner Units will be entitled to receive, when, as and if declared by the
Partnership acting through the General Partner out of funds legally available
for the payment of distributions, cumulative preferential cash distributions at
the rate per annum of 8.75% of the Stated Value. Distributions will be
cumulative, will accrue from November 12, 1998, the original issue date of the
Series B Preferred Limited Partner Units, and will be payable quarterly in
arrears on March 31, June 30, September 30 and December 31 (each a "SERIES B
DISTRIBUTION PAYMENT DATE") of each year, commencing on December 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 B Distribution Payment Date is not
a Business Day, then payment of the distribution to be made on such Series B
Distribution Payment Date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay) except that if such Business Day is in the next succeeding calendar year,
such payment shall be made on the immediately preceding Business Day, in each
case with the same force and effect as if made on such Series B Distribution
Payment Date. Each such distribution will be payable to the holders of record of
the Series B Preferred Limited Partner Units as they appear on the books of the
Partnership or any transfer agent for the Series B Preferred Limited Partner
Units on such record dates selected by the General Partner, not less than 10 nor
more than 50 days preceding the applicable Series B Distribution Payment Date.

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

     (c) So long as any Series B Preferred Limited Partner Units are
outstanding, no distribution shall be paid or declared on or with respect to the
Common Limited Partner Interests or the General Partner Interests or any other
series of outstanding Preferred Limited Partner Interests ranking junior as to
the payment of distributions to the Series B Preferred Limited Partner Units,
nor shall any sum or sums be set aside for or applied to the purchase or
redemption of the Series B Preferred Limited Partner Units or any other series
of outstanding

                                        2

<PAGE>   86


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

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

                                        3

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

     SECTION 5. Redemption. (a) The Series B Preferred Limited Partner Units may
not be redeemed prior to November 12, 2003. On or after such date the
Partnership shall have the right to redeem the Series B Preferred Limited
Partner Units, in whole or in part, from time to time, upon notice as provided
in Section 5(b) below, at a redemption price equal to the Stated Value per
Series B Preferred Limited Partner Unit plus accumulated and unpaid
distributions to the date of payment (the "Series B Redemption Price"), provided
that the Partnership may not redeem fewer than all the outstanding Series B
Preferred Limited Partner Units unless all accumulated and unpaid distributions
have been paid on all Series

                                        4

<PAGE>   88

B Preferred Limited Partner Units for all quarterly distribution periods
ending on or prior to the date of redemption.

     (b) The Partnership will provide notice of any redemption of the Series B
Preferred Limited Partner Units to the holders of record thereof not less than
30 nor more than 60 days prior to the date of redemption. Such notice shall be
provided by sending notice of such redemption, by (i) fax and (ii) certified
mail postage prepaid, to each holder of Series B Preferred Limited Partner Units
to be redeemed, at such holder's address as it appears on the transfer records
of the Partnership. Each such notice shall state, as appropriate, the following:

                  (i)  the redemption date;

                  (ii) the Series B Redemption Price;

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

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

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

                  (vi) that on or after the redemption date distributions on the
         Series B Preferred Limited Partner Units 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 of any Series B Preferred Limited
Partner Units except as to the bolder to which notice was, defective or not
given.

     (c) If notice (which notice will be irrevocable) has been given as provided
above then, by 12:00 noon, New York City time, on the redemption date, the
Partnership will deposit irrevocably in trust for the benefit of the Series. B
Preferred Limited Partner Units being redeemed funds sufficient to pay the
applicable Series B Redemption Price and will give irrevocable instructions and
authority to pay such Series B Redemption Price to the holders of the Series B
Preferred Limited Partner Units entitled thereto. If notice shall have been
given provided above and funds deposited as required, then upon the date of
such deposit, distributions will cease to accrue on the Series B Preferred
Limited Partner Units called for redemption, such Series B Preferred Limited
Partner ,will no longer be deemed to be outstanding and all rights of holders of
such Series

                                       5
<PAGE>   89

B Preferred Limited Partner Units so called for redemption will cease, except
the right of the holders of such Series B Preferred Limited Partner Units to
receive the applicable Series B Redemption Price but without interest thereon.
If any date fixed for redemption of Series B Preferred Limited Partner Units is
not a Business Day, then payment of the Series B 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 Series B
Redemption Price in respect of the Series B Preferred Limited Partner Units is
improperly withheld or refused and not paid by the Partnership, distributions on
such Series B Preferred Limited Partner Units will continue to accumulate 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 applicable Series B
Redemption Price. If fewer than all of the Series B Preferred Limited Partner
Units are to be redeemed, the General Partner shall select Series B Preferred
Limited Partner Units to be redeemed by lot or pro rata (as nearly as
practicable without creating fractional units) or in some other equitable manner
determined by the General Partner in its sole discretion. Upon presentation of
any certificate for Series B Preferred Limited Partner Unit redeemed in part
only, the Partnership shall execute and deliver, at the expense of the
Partnership, a new certificate equal to the unredeemed portion of the
Certificate so presented.

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

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

     (f) Notwithstanding any other provision of this Section 5, the Series B
Redemption Price (other than the portion thereof consisting of accumulated and
unpaid distributions) shall be payable solely out of the sales proceeds of
capital stock of the General Partner, which will be contributed by the General
Partner to

                                        6

<PAGE>   90

the Partnership as an additional capital contribution in accordance with Section
4.5.E of the Partnership Agreement, or the sale proceeds of Limited Partner
Interests and from no other source, it being understood that this Section 5(g)
shall not be applicable to payment of the Series B Liquidation Preference
Amount.

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

     (b) So long as any Series B Preferred Limited Partner Units remain
outstanding, the Partnership shall not, without the affirmative vote of the
holders of at least 66-2/3% of the Series B Preferred Limited Partner Units
outstanding at the time (i) authorize or create, or increase the authorized or
issued amount of, any class or series of Preferred Limited Partner Interests
ranking prior to the Series B Preferred Limited Partner Units with respect to
payment of distributions or rights upon liquidation, dissolution or winding-up,
or reclassify any Partnership Interests of the Partnership into any such
Preferred Limited Partner Interests, or create, authorize or issue any
obligation or security convertible into or evidencing the right to purchase any
such Partnership Interests, (ii) authorize or create, or increase the authorized
or issued amount of any Preferred Limited Partner Interests on a parity, with
the Series B Preferred Limited Partner Units or reclassify any Partnership
Interests of the Partnership into any such Preferred Limited Partner Interests
or create, authorize or issue any obligation or security convertible into or
evidencing the right to purchase any such Preferred Limited Partner Interests
but only to the extent such Preferred Limited Partner Interests are issued to an
affiliate of the Partnership, other than (x) the General Partner or IAC Capital
Trust to the extent the issuance of such interests was to allow the General
Partner or IAC Capital Trust to issue corresponding preferred stock or
preferred securities lo persons who are not, affiliates of the Partnership or
(y) The Irvine Company or an affiliate of The Irvine Company (provided that the
transaction is approved by the Independent Directors Committee of the General
Partner's Board of Directors pursuant to Article III, Section 4(c)(ii) of the
General Partner's bylaws), or (iii) either consolidate, merge into or with, or
convey, transfer or lease its assets substantially as an entirety to, any
corporation or other entity, or amend, alter or repeal the provisions of the
Partnership Agreement (including, without limitation, this Designation
Instrument), whether by merger, consolidation or otherwise, in each case in a
manner that would materially and adversely affect the powers, special rights,
preferences, privileges or voting power of the Series B Preferred Limited
Partner Units or the holders thereof, provided, however, that with respect to
the occurrence of any event set forth in (iii) above, so long as (A) the
Partnership is the surviving entity and the Series B Preferred Limited Partner

                                        7

<PAGE>   91

Units remain outstanding with the terms thereof unchanged, or (B) the
resulting, surviving or transferee entity is a partnership, limited liability
company or other pass-through entity organized under the laws of any state and
substitutes the Series B Preferred Limited Partner Units for other interests in
such entity having substantially the same terms and rights as the Series B
Preferred Limited Partner Units, including with respect to distributions,
redemptions, transfers, voting rights and rights upon liquidation, dissolution
or winding-up, then the occurrence of any such event shall not be deemed to
materially and adversely affect such rights, privileges or voting powers of the
holders of the Series B Preferred Limited Partner Units; and provided further,
that any increase in the amount of Partnership Interests or the creation or
issuance of any other class or series of Partnership Interests, in each case
ranking (1) junior to the Series B Preferred Limited Partner Units with respect
to payment of distributions or the distribution of assets upon liquidation,
dissolution or winding-up, or (2) on a parity to the Preferred Limited Partner
Units with respect to payment of distributions or the distribution of assets
upon liquidation, dissolution or winding-up to the extent such Partnership
Interests are not issued to an affiliate of the Partnership other than the
General Partner or IAC Capital Trust to the extent the issuance of such
Partnership Interests was to allow the General Partner or IAC Capital Trust to
issue corresponding preferred stock or preferred securities to persons who are
not affiliates of the Partnership, shall not be deemed to materially and
adversely affect such rights, preferences, privileges or voting powers.

     SECTION 7. Restrictions on Ownership and Transfer. (a) The Series B
Preferred Limited Partner Units (i) are being issued in a private placement and
(ii) shall be subject to the restrictions on Transfer set forth in the
Partnership Agreement.

     (b) Any Holder of Series B Preferred Limited Partner Units may only
Transfer Series B Preferred Limited Partner Units after delivery of an opinion
of independent legal counsel familiar with such matters to the effect that such
Transfer will not result in the Partnership being treated as an association
taxable as a corporation. In addition, no such Transfer may be effectuated
through an "established securities market" or a "secondary market (or the
substantial equivalent thereof)" within the meaning of Section 7704 of the
Code.

     (c) If Greene Street 1998 Exchange Fund, L.P., as the bolder of Series B
Preferred Limited Partner Units (the "FUND"), concludes based on results or
projected results that there exists (in the reasonable judgment of the Fund) an
imminent and substantial risk that the Fund's interest in the Partnership
represents or will represent more the 19.5% of the total profits or capital
interests in the Partnership for a taxable year (the "19.5% LIMIT" (determined
in accordance with Treasury Regulations Section 1.731-2(c)(4)), then the Fund
shall, subject to

                                       8
<PAGE>   92

the limitations in Sections 7(a) and 7(b), be permitted to Transfer so much of
its Series B Preferred Limited Partner Units as may be appropriate to alleviate
the risk of not satisfying the 19.5% Limit. In the event that the Fund makes
such a determination, but is unable to comply with the provisions of Section
7(b), the Fund will be entitled to deliver an Exchange Notice (as defined) with
respect to the number of Series B Preferred Limited Partner Units as may be
appropriate to alleviate the risk of not satisfying the 19.5% Limit,
notwithstanding the fact that the Fund would not otherwise be able to exchange
such Series B Preferred Limited Partner Units. The procedures for exchange shall
otherwise be as provided in Section 9.

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

     SECTION 9. Exchange Rights.

     (a) Holders' Right to Exchange.

                  (i) Series B Preferred Limited Partner Units will be
         exchangeable in whole but not in part unless expressly otherwise
         provided herein at any time on or after November 12, 2008, at the
         option of 51% of the holders of all outstanding Series B Preferred
         Limited Partner Units, for authorized but previously unissued
         Alternative Preferred Securities (as defined in Section 9(e)) at an
         exchange rate of one Alternative Preferred Security for one Series B
         Preferred Limited Partner Unit, subject to adjustment as described
         below, provided that the Series B Preferred Limited Partner Units will
         become exchangeable at any time, in whole but not in part unless
         expressly otherwise provided herein, at the option of 51% of the
         holders of all outstanding Series B Preferred Limited Partner Units for
         Alternative Preferred Securities if (x) at any time full distributions
         shall not have been timely made on any Series B Preferred Limited
         Partner Unit with respect to six (6) prior quarterly distribution
         periods, whether or not consecutive, provided, however, that a
         distribution in respect of Series B Preferred Limited Partner Units
         shall be considered timely made if made within two (2) Business Days
         after the applicable Series B Distribution Payment Date if at the time
         of such late payment there shall not be any prior quarterly
         distribution periods in respect of which full distributions were not
         timely made, or (y) upon receipt by a

                                       9
<PAGE>   93
         holder or holders of Series B Preferred Limited Partner Units of (A)
         notice from the General Partner that the General Partner or a
         Subsidiary of the General Partner has taken the position that the
         Partnership is, or upon the consummation of an identified event in the
         immediate future will be, a "Publicly Traded Partnership" (a "PTP")
         within the meaning of Section 7704 of the Code and (B) an opinion
         rendered by independent counsel familiar with such matters addressed to
         a holder or holders of Series B Preferred Limited Partner Units, that
         the Partnership is or likely is, or upon the occurrence of a defined
         event in the immediate future will be or likely will be, a PTP. In
         addition, the Series B Preferred Limited Partner Units may be exchanged
         for Alternative Preferred Securities, in whole but not in part unless
         expressly otherwise provided herein, at the option of 51% of the
         holders of all outstanding Series B Preferred Limited Partner Units
         after November 12, 2001 and prior to November 12, 2008 if such holders
         of Series B Preferred Limited Partner Units shall deliver to the
         General Partner either (A) a private letter ruling addressed to such
         holder(s)of Series B Preferred Limited Partner Units or (B) an opinion
         of independent counsel familiar with such matters based on the
         enactment of temporary or final Treasury Regulations or the publication
         of a Revenue Ruling, in either case to the effect that such exchange of
         the Series B Preferred Limited Partner Units at such earlier time would
         not cause the Series B Preferred Limited Partner Units to be considered
         "stock and securities" within the meaning of Section 351(c) of the
         Code for purposes of determining whether the holder of such Series B
         Preferred Limited Partner Units is an "investment company" under
         Section 721(b) of the Code if an exchange is permitted at such
         earlier date. Furthermore, the Series B Preferred Limited Partner Units
         held by the Fund, if the Fund so determines, may be exchanged in whole
         or in part for Alternative Preferred Securities if the Fund concludes
         based on results or projected results that there exists (in the
         reasonable judgment of the Fund) an imminent and substantial risk that
         the Fund's interest in the Partnership represents or will exceed the
         19.5% Limit.

         (ii) Notwithstanding anything to the contrary set forth in Section
         9(a)(i), if an Exchange Notice (as defined herein) has been delivered
         to the General Partner, then the General Partner may, at its option,
         within ten (10) Business Days after receipt of the Exchange Notice,
         elect to cause the Partnership to redeem all or a portion of the
         outstanding Series B Preferred Limited Partner Units for cash in an
         amount equal to the Stated Value per Series B Preferred Limited Partner
         Unit and unpaid distributions to the date of redemption. If the General
         Partner elects to redeem fewer than all of the outstanding Series B
         Preferred Limited Partner Units, the number of Series B Preferred
         Limited Partner Units held by each holder to be

                                       10
<PAGE>   94
           redeemed shall equal such holder's pro rata share (based on the
           percentage of the aggregate number of outstanding Series B Preferred
           Limited Partner Units that the total number of Series B Preferred
           Limited Partner Units held by such holder represents) of the
           aggregate number of Series B Preferred Limited Partner Units being
           redeemed.

     (iii) In the event an exchange of all Series B Preferred Limited Partner
           Units pursuant to Section 9(a) would violate the provisions on
           ownership limitations of (x) the General Partner set forth in Article
           Sixth, Section (c)(4) of the Certificate of Incorporation or (y) of
           IAC Capital Trust set forth in Section 8.2 of the Declaration of
           Trust, each holder of Series B Preferred Limited Partner Units shall
           be entitled to exchange, pursuant to the provisions of Section 9(b),
           a number of Series B Preferred Limited Partner Units which would
           comply with the provisions on ownership limitations of the General
           Partner or IAC Capital Trust, as the case may be, and any Series B
           Preferred Limited Partner Units not so exchanged (the "EXCESS UNITS"
           shall be redeemed by the Partnership for cash in an amount equal to
           the Stated Value per Excess Unit, plus any accumulated and unpaid
           distributions to the date of redemption, subject to any restriction
           thereon contained in any debt instrument or agreement of the
           Partnership.

     (b) Procedure for Exchange and/or Redemption of Series B Preferred Limited
Partner Units.

     (i)   Any exchange shall be exercised pursuant to a notice of exchange (the
           "EXCHANGE NOTICE" delivered to the General Partner by the Partners
           representing at least 51% of the outstanding Series B Preferred
           Limited Partner Units (or by the Fund in the case of an exchange
           pursuant to the last sentence of Section 9(a)(i) hereof) by (a) fax
           and (b) certified mail postage prepaid. The General Partner may
           effect any exchange of Series B Preferred Limited Partner Units, or
           exercise its option to cause the Partnership to redeem any portion of
           the Series B Preferred Limited Partner Units for cash pursuant to
           Section 9(a)(ii) or redeem Excess Units pursuant to Section
           9(a)(iii), by delivering to each holder of record of Series B
           Preferred Limited Partner Units, within ten (10) Business Days
           following receipt of the Exchange Notice, (a) if the General Partner
           elects to cause the Partnership to acquire any of the Series B
           Preferred Limited Partner Units then outstanding, (1) certificates
           representing the Alternative Preferred Securities being issued in
           exchange for the Series B Preferred Limited Partner Units of such
           holder being exchanged and (2) a written notice stating (A) the
           redemption date, which may be the date of such written notice or any
           other date which is not later than sixty (60) days

surrendered, (D) that distributions on the Series B Preferred Limited Partner
Units will cease to accrue on such redemption date and (E) the Alternative
Preferred Securities to be delivered, or (b) if the General Partner elects to

Preferred Limited Partner Units shall be deemed canceled (and any corresponding
Partnership Interest represented thereby deemed terminated) simultaneously with
the delivery of Alternative Preferred Securities (with respect to Series B
Preferred Limited Partner Units exchanged) or simultaneously with the redemption
date (with respect to Series B Preferred Limited Partner Units redeemed).
Holders of Series B Preferred Limited Partner Units shall deliver any canceled
certificates representing Series B Preferred Limited Partner Units which have
been exchanged or redeemed to the office of the General Partner within ten (10)
Business Days of the exchange or redemption with respect thereto.
Notwithstanding anything to the contrary contained herein, any and all Series B
Preferred Limited Partner Units to be exchanged for Alternative Preferred
Securities pursuant to this Section 9 shall be so exchanged in a single
transaction at one time. As a condition to exchange, the General Partner may
require the holders of Series B Preferred Limited Partner Units to make such
representations as may be reasonably necessary for the General Partner to
establish that the issuance of Alternative Preferred Securities pursuant to the
exchange shall not be required to be registered under the Securities Act or any
state securities laws. Any Alternative Preferred Securities issued pursuant to
this Section 9 shall be delivered as shares which are duly authorized, validly
issued, fully paid and non assessable, free of any pledge, lien, encumbrance or
restriction other than those provided in the Certificate of Incorporation or the
by-laws of the General Partner or the Declaration of Trust, as the case may be,
the Securities Act and relevant state securities or blue sky laws. The
certificates representing the Alternative Preferred Securities issued upon
exchange of the Series B Preferred Limited Partner Units shall contain the
following legend:

         THIS CERTIFICATE AND THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE

            APPLICABLE STATE SECURITIES LAWS OR UNLESS AN EXEMPTION FROM
            REGISTRATION IS AVAILABLE.

                  (ii) In the event of an exchange of Series B Preferred Limited
         Partner Units for Alternative Preferred Securities, an amount equal to
         the accumulated and unpaid distributions to the date of exchange on any
         Series B Preferred Limited Partner Units tendered for exchange shall
         (i) accrue on the Alternative Preferred Securities into which such
         Series B Preferred Limited Partner Units are exchanged, and (ii)
         continue to accrue on such Series B Preferred Limited Partner Units,
         which shall remain outstanding following such exchange, with the
         General Partner as the holder of such Series B Preferred Limited
         Partner Units, (iii) Fractional Alternative Preferred Securities are
         not to be issued upon exchange but, in lien thereof, the General
         Partner or IAC, Capital Trust will pay a cash judgment based upon the
         fair market value of the Alternative Preferred Securities on the day
         prior to the exchange date as determined in good faith by the Board of
         Directors of the General Partner or the Regular Trustee(s) of IAC
         Capital Trust, as the case may be.

     (c) Adjustment of Exchange Price. In case the General Partner or IAC
Capital Trust, as the case may be, shall be a party to any transaction
(including, without limitation, a merger, consolidation, statutory share
exchange, tender offer for all or substantially all of the General Partner's
capital stock or IAC Capital Trust's capital securities or sale of all or
substantially all of the General Partner's or IAC Capital Trust's assets), in
each case as a result of which the Alternative Preferred Securities will be
converted into the right to receive shares of capital stock, other securities or
other property (including cash or any combination thereof), each Series B
Preferred Limited Partner Unit will thereafter be exchangeable into the kind and
amount of shares of capital stock and other securities and property receivable
(including cash or any combination thereof) upon the consummation of such
transaction by a holder of that number of Alternative Preferred Securities or
fraction thereof into which one Series B Preferred Limited Partner Unit was
exchangeable immediately prior to such transaction. The General Partner may not
become a party to any such transaction, unless the terms thereof are consistent
with the foregoing.
