ITEM 1. BUSINESS
 
ORGANIZATION AND GENERAL BUSINESS DESCRIPTION
 
     Irvine Apartment Communities, Inc. (the "Company"), a Maryland corporation,
operates as a real estate investment trust ("REIT") under the Internal Revenue
Code of 1986, as amended. At December 31, 1998, the Company had a 44.6% general
partnership interest in and was the sole managing general partner of Irvine
Apartment Communities, L.P. (the "Operating Partnership"), which began
operations December 8, 1993, the date of the Company's initial public offering
of common stock (the "Offering"). At December 31, 1998, The Irvine Company and
certain of its affiliates had a 55.2% limited partnership interest in the
Operating Partnership. In addition, at December 31, 1998, The Irvine Company and
certain of its affiliates owned approximately 17.9% of the common stock of the
Company. As used herein, unless the context otherwise requires, the term
"Company" includes Irvine Apartment Communities, Inc. and Irvine Apartment
Communities, L.P.
 
     The Company is a self-administered equity REIT engaged in the operation and
development of apartment communities in Orange County, California and, beginning
in 1997 other locations in California. The Company's intent is to create new
market positions in California which possess rental demographic and economic
growth prospects similar to those on the Irvine Ranch. As of December 31, 1998,
the Operating Partnership owned and operated 65 properties (the "Properties")
containing 16,439 operating apartment units and had 3,039 units under
construction or development. Until July 2020, the Company has the exclusive
right, but not the obligation, to acquire land from The Irvine Company for
development of additional apartment communities on the Irvine Ranch.
 
     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 Company. The Trust exists for the sole purpose of issuing its preferred
securities and investing the proceeds thereof in preferred limited partner units
of the Operating Partnership. In January 1998, the Trust issued 6.0 million of
8 1/4% Series A Preferred Securities resulting in gross proceeds of $150
million.
 
     In March 1998, the Operating Partnership and Western National Property
Management ("WNPM") entered into a strategic alliance that, in April 1998,
assumed all property management responsibilities for the Operating Partnership's
Southern California portfolio. The new entity, Irvine Apartment Management
Company ("IAMC"), is owned 51% by the Operating Partnership and 49% by WNPM. The
Company believes that this strategic alliance creates greater efficiencies and
enhances service to customers.
 
     The address of the Company is 550 Newport Center Drive, Suite 300, Newport
Beach, California 92660. Its telephone number is (949) 720-5500.
 
  Going Private Transaction
 
     On February 1, 1999, the Company and TIC Acquisition LLC, an indirect
wholly owned subsidiary of The Irvine Company, entered into a definitive merger
agreement providing for a merger of the Company into TIC Acquisition LLC in
which the Company's shareholders will receive $34 in cash per share. The
transaction, which is subject to the approval of the holders of (i) at least
two-thirds of the outstanding shares of common stock of the Company and (ii) a
number of shares of common stock of the Company (excluding the shares held by
TIC Acquisition LLC and its affiliates) representing a majority of the total
number of shares of common stock of the Company entitled to vote, and other
customary conditions, is expected to be completed late in the second quarter or
early in the third quarter of 1999.
 
FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS
 
     The Company operates in one business segment, that of owning, operating and
developing apartment communities in California. See the consolidated financial
statements and notes thereto included in Item 8 of this Annual Report on Form
10-K for financial information about the industry segment.

DESCRIPTION OF BUSINESS
 
     As of December 31, 1998, the Operating Partnership owned and operated 55
stabilized properties containing 15,975 units (the "Stabilized Communities").
Together with the units under construction or development (the "Communities
Under Development"), the Operating Partnership owns a total of 19,478 units.
Through July 2020, the Company holds the exclusive right, but not the
obligation, to acquire land from The Irvine Company, the owner and developer of
the Irvine Ranch since 1864, for development of additional apartment communities
on the Irvine Ranch.
 
     The Irvine Ranch is located in central Orange County, California, between
San Diego and Los Angeles. The western boundary of the Irvine Ranch borders
approximately six miles of the Pacific Ocean. Today, the portion of the Irvine
Ranch which is still owned by The Irvine Company covers approximately 90 square
miles and includes more than 50,000 undeveloped acres. The developed portion of
the Irvine Ranch, which includes significant parts of the cities of Irvine,
Newport Beach and Tustin, is one of the largest urban master-planned communities
in the United States. The Irvine Ranch has been developed over the past 30 years
in accordance with an original master plan (the "Master Plan") which, over time,
has been refined to accord with locally approved general plans. The Irvine Ranch
is one of the major commercial, retail and residential centers in Southern
California.
 
     In 1997, the Company commenced operations in Northern California's Silicon
Valley and the northern coastal markets of San Diego County. In 1998, the
Company purchased a property in Los Angeles County. The Company's intent is to
create new market positions in California which possess rental demographics and
economic growth prospects similar to those on the Irvine Ranch. See "Business
Strategy -- Off-Ranch Expansion."
 
     For the year ended December 31, 1998, the average physical occupancy
(number of units occupied divided by the total number of units) of the
Stabilized Communities was 94.1% and the average monthly rent per unit was
$1,213. The Communities Under Development will include a total of 3,503
apartment units and have an aggregate estimated cost of approximately $622
million. As of December 31, 1998, 464 units were completed with 403 units
occupied and generating rental revenue in Communities Under Development.
 
     The information set forth in this Annual Report on Form 10-K relating to
the expansion program, the timing of future commencement and completion of
construction, the commencement of leasing activity and initial stabilized
occupancy, the estimated costs of apartment communities that are in development
and the completion and timing of completion of the merger of the Company into
TIC Acquisition LLC are forward-looking statements. Actual results will depend
on numerous factors, many of which are beyond the control of the Company. These
include the extent and timing of economic growth in the Company's rental
markets; future trends in the pricing of construction materials and labor;
product design changes; entitlement decisions by local government authorities;
weather patterns; changes in interest rate levels; other changes in capital
markets; unanticipated regulatory delays; and third party interest in acquiring
the Company. No assurance can be given that the timing or estimates will not
vary substantially from actual results.
 
BUSINESS STRATEGY
 
  Operating Strategies
 
- - Provide an exceptional living environment for residents. The Properties are
  developed and maintained to appeal to the highly educated, relatively affluent
  base of renters. As a result of the region's closely managed master-planning
  process, the Properties are and will be situated amid parks and other open
  space, and in close proximity to employment centers, schools, retail centers,
  and recreational facilities. They provide numerous amenities, are well
  maintained and offer a high standard of customer service.
 
- - Enhance efficiency of operations. The Company had historically subcontracted
  on-site staffing, personnel management and accounting functions to four
  independent property management firms. In March 1998, the Operating
  Partnership and WNPM entered into a strategic alliance that, in April 1998,
  assumed all property management responsibilities for the Operating
  Partnership's Southern California portfolio. The new entity, IAMC, is owned
  51% by the Operating Partnership and 49% by WNPM. By centralizing all
 
                                        4
<PAGE>   5
 
  property management functions into one entity, the new strategic alliance
  provides greater efficiencies, reduces property management fees and property
  management costs, improves training of on-site employees and enhances service
  to customers. WNPM is the managing member of IAMC and responsible for its day
  to day operations, but the Company, through its control of a majority of the
  board of directors of IAMC, has significant control over IAMC including
  approval of business plans and budgets, compensation, and the employment of
  the executive officers of IAMC. In addition, the Company pays IAMC a property
  management fee which is adjusted to reflect the actual operating performance
  of the Properties, thereby more closely aligning the interests of IAMC and the
  Company. The Company also granted 100,000 options to certain executives of
  WNPM in order to better align their interests with the Company. Commencing in
  April 2001, the Company will also have the right, but not the obligation, to
  purchase WNPM's interest in IAMC at a nominal cost.
 
- - Capitalize on strong brand identity with enhanced marketing and merchandising
  programs. The Company has enhanced certain of its marketing programs to
  broaden its brand name recognition in order to attract new residents into its
  portfolio and broaden the existing resident base. The Company's marketing
  programs include: a website and a single source 800 telephone number to
  provide information on the Properties; rental information centers within a
  major shopping center and the University of California at Irvine; and a
  targeted advertising campaign promoting the Company's portfolio and its
  quality of life characteristics.
 
  Development Strategies
 
- - Develop new communities to complement and expand the Company's existing rental
  market base. The broad employment and renter base on the Irvine Ranch allows
  development of a variety of apartment property types and amenity levels,
  including projects designed for the family, luxury and senior markets, and the
  area's large population of young professionals. The Company's development
  program through market segmentation, identifies target markets and, supported
  by consumer research and focus group studies, market segmentation decisions
  are made at the earliest planning stages, when new residential villages for
  the Irvine Ranch are conceived and the villages' largest and most important
  amenities are selected. Location of schools, recreational facilities, retail
  centers, open space and views are all important considerations. Individual
  development decisions -- including site location, product design, amenities
  and marketing programs -- are also geared to appeal to the needs and desires
  of the target rental market.
 
- - Utilize experienced management to create high-quality, well-built properties
  designed to sustain their value. The Company brings considerable management
  expertise to all aspects of the development, construction and leasing process.
  Senior management is actively involved in new project development from the
  inception of a new Irvine Ranch village and is responsible for target market
  identification; design of site plans, building plans, and floor plans; project
  and unit amenity selection; and site-specific governmental approvals. In
  addition, the Company directs the bidding and contracting of all major
  construction activities, in essence acting as general contractor. The Company
  engages experienced independent construction managers to act as intermediaries
  with subcontractors and to manage on-site activities under the close
  supervision of the Company's internal construction group. The Company builds
  properties using high-quality construction materials and techniques, and
  believes that this higher initial investment in quality enhances long-term
  value creation by sustaining high community rental income levels and reducing
  long-term expense levels.
 
  "Off-Ranch" Expansion
 
     While the Company's principal focus has been on the development of
apartment communities on the Irvine Ranch, in 1997 the Company commenced an
"off-Ranch" expansion program. The Company's strategic growth plan is designed
to create meaningful market positions off the Irvine Ranch in some of
California's most promising growth centers by developing or acquiring apartment
communities in areas that possess rental demographics and economic growth
prospects similar to those on the Irvine Ranch.
 
     Initially, the Company's "off-Ranch" expansion program was centered in
Northern California's Silicon Valley and the northern coastal markets of San
Diego County. In 1997, the Company acquired a 923-unit apartment community (The
Villas of Renaissance) located in the La Jolla region of Northern San Diego
 
                                        5
<PAGE>   6
 
County. In 1998, the Company completed construction of a 342-unit apartment
community (The Hamptons at Cupertino) in the Silicon Valley and began
construction on three additional apartment communities (with a total of
approximately 660 units) in the Silicon Valley and two additional apartment
communities (with a total of approximately 560 units) in Northern San Diego
County. Also in 1998, the Company purchased a 119-unit, high-rise apartment
building under renovation located in Santa Monica (1221 Ocean Avenue).
 
     The Company has also entered into an agreement giving it the right, but not
the obligation, to acquire a development site in Northern California for the
development of over 2,000 apartment units. The Company's decision whether to
exercise the option is subject to completion of necessary due diligence and the
receipt of all necessary entitlements. Accordingly, no assurance can be given
that the option will be exercised.
 
  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 entitlements for
its developments. The goal of the Master Plan was and remains to create
innovative urban and suburban environments through the well-planned, coordinated
development of residential communities and employment centers (which include
major business and retail centers, and research and development and industrial
parks) as well as civic, cultural, recreational, educational and other
supportive facilities, all with an emphasis on improving the quality of life and
achieving long-term balanced regional economic growth.
 
     The success of the Irvine Ranch as a master-planned development is, in
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.
 
  Market Segmentation and the Village Concept
 
     The Irvine Company's land use planning emphasizes market segmentation in
order to ensure adequate and appropriate allocation of land uses which support
sustained growth for the long term. Through careful planning, design and
marketing, The Irvine Company also promotes compatibility and synergy among
properties of the same type in order to maximize the likelihood of success of
new projects, to preserve and build value for existing projects and to build
sustainable long-term market value for homeowners, local merchants and
employers. In accordance with the Master Plan, The Irvine Company has created
twelve villages which are used as micro-planning areas in an effort to
facilitate the desired segmentation of products.
 
                                        6
<PAGE>   7
 
     Each village across the Irvine Ranch has a thematic identity which
characterizes the primary features and attributes of the village and helps to
identify the target market for the Company's product. For example, Tustin Ranch,
in the City of Tustin, is a family-oriented village featuring an 18-hole
championship gold course, athletic fields, jogging, hiking and equestrian
trails. Along the ocean is the village of Newport Coast, an upscale community
featuring ocean views and million-dollar custom built homes. The Village of
Westpark, in Irvine, caters to young professionals with growing families and
offers the highly renowned public school system and recreational facilities of
the City of Irvine.
 
     Within each village, the Company's target market is further defined. The
primary factor which determines the appropriate target for the product is
location. For example, the conventional product which is targeted towards young
professionals is typically located near major business centers and in close
proximity to entertainment, retail establishments and major transportation
corridors. The student product, on the other hand, is located within walking
distance of a college or university, student-oriented retail centers, and public
transportation.
 
     Finally, the Company specifically designs its products to appeal to a
target market. The Company's luxury product is typically in a unique location
with ocean and golf course views. The family product offers spacious play areas
and tot lots, a children's multi-purpose room with an activities coordinator,
individual garages and in-unit washers and dryers.
 
  Exclusive Land Rights Agreement
 
     The Company and The Irvine Company are parties to the Land Rights Agreement
pursuant to which, through July 31, 2020, the Company has the exclusive right,
but not the obligation, to acquire all land sites entitled for residential use
and designated by The Irvine Company as ready for apartment community
development in accordance with The Irvine Company's Master Plan. The
determination to exercise an option with respect to a site is made solely by the
Independent Directors Committee of the Company's Board of Directors. The Irvine
Company has no obligation to designate any land for sale and development of
additional apartment communities. Under this Agreement, the Operating
Partnership has purchased ten apartment community land sites since the Offering.
Under the terms of the Land Rights Agreement, through July 31, 2000, the
purchase price for any apartment community sites acquired may be paid with
either cash, Common Stock of the Company or common limited partnership interests
in the Operating Partnership ("Common L.P. Units"), at the option of the
Company. After July 31, 2000, the choice of consideration will revert to The
Irvine Company. In no event shall the purchase price for any apartment community
land site exceed 95% of the value of such site as determined by independent
appraisals. In addition, the purchase price for apartment sites which
encompassed the first 1,800 apartment units the Company developed commencing in
mid-1995 were set at an amount such that each project's budgeted pro forma
unleveraged return on costs for the first 12 months following stabilized
occupancy was between 10.0% and 10.5%. Seven land sites for the development of
apartment communities which contain 1,884 units have been purchased under this
arrangement. Accordingly, the purchase price for all future land sites will be
no greater than 95% of the appraised value. Independent appraisals will be
obtained by each of the Company and The Irvine Company for all future sites,
prior to the Independent Directors Committee determining whether the Company
will exercise its right to purchase a land site. The Irvine Company may not
develop, construct, maintain, operate, use, lease or sell land or any
improvements thereon, for apartment use, without the express written consent of
the Operating Partnership. If the Company elects not to exercise its option for
any site, the Company will thereafter have a right of first refusal on the sale
of such site to a third party if the terms of such sale are more favorable than
those offered to the Company. The determination to exercise an option or the
right of first refusal under the Land Rights Agreement with respect to any site
will be made solely by a majority of the Independent Directors Committee.
 
     Pursuant to the Land Rights Agreement, The Irvine Company and its Chairman,
Donald Bren, have agreed to conduct their apartment community development and
ownership activities on the Irvine Ranch solely through the Company. These
restrictions terminate upon the occurrence of certain conditions.

  Capital and Financing Strategies
 
     The Company intends to maintain a conservative ratio of debt to total
market capitalization (the market value of issued and outstanding shares of
common stock of the Company and the common limited partnership units of the
Operating Partnership plus total minority redeemable preferred interests and
debt) of not greater than 60%. As of December 31, 1998, the ratio of debt to
total market capitalization was 31%.
 
     The Company has established a debt policy relative to its total market
capitalization, a ratio commonly employed by REITs, rather than to the book
value of its assets because the Company believes that the book value of its
assets (which to a large extent is the depreciated value of its apartments) does
not accurately reflect its ability to borrow and to meet debt service
requirements. The market capitalization of the Company, however, is more
variable than book value and does not necessarily reflect the fair market value
of the underlying assets of the Company. Although the Company will consider
factors other than market capitalization in making decisions regarding the
incurrence of debt and the issuance of preferred limited partner units by the
Operating Partnership (such as the estimated market value of such properties
upon refinancing, and the ability of particular properties and the Company as a
whole to generate cash flow to cover expected debt services), there can be no
assurance that the Company will maintain the ratio of debt to market
capitalization (or to any other measure of asset value) described above.
 
     The Company completed four significant equity and financing transactions in
1998. In January, the Trust issued 6.0 million of its 8 1/4% Series A Preferred
Securities. The gross proceeds of $150 million were used to purchase an
equivalent amount of 8 1/4% Series A Preferred Limited Partner Units in the
Operating Partnership. The Operating Partnership used the $150 million of
proceeds, net of issuance costs, all of which were paid by the Operating
Partnership, to repay the outstanding borrowings under the unsecured line of
credit and to fund development of new apartment communities. In May, the Company
priced 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 this offering were used to refinance the Company's existing tax-exempt
mortgage debt. In November, the Company completed a $50 million private
placement of preferred securities yielding 8.75%. The net proceeds were used to
reduce the outstanding balance on the Company's unsecured line of credit. Also
in November, the Company placed a $100 million unsecured term loan at an
interest rate of 6.11%. The net proceeds were used to reduce the outstanding
balance on the Company's unsecured line of credit and to fund the Company's
ongoing development program. All of these transactions are more fully discussed
in Management's Discussion and Analysis included in this Annual Report on Form
10-K.
 
COMPETITION
 
     The Properties are located in developed areas. There are numerous other
rental apartment properties within and around the market area of each property.
The number of competitive rental properties in the area could have a material
effect on the Company's ability to rent apartments and increase rents.
 
EMPLOYEES
 
     As of February 10, 1999, the Company had 68 employees. None of the
Company's employees are subject to a collective bargaining agreement and the
Company has experienced no labor-related work stoppages. The Company considers
its relations with its personnel to be good.
 
TAX STATUS
 
     The Company has made an election to be taxed as a REIT under Sections 856
through 860 of the Internal Revenue Code of 1986, as amended (the "Code"). The
Company generally will not be subject to federal income tax to the extent it
distributes at least 95% of its REIT taxable income to its shareholders. If the
Company fails to qualify as a REIT in any taxable year, the Company will be
subject to federal income tax (including any applicable alternative minimum tax)
on its taxable income at regular corporate rates. Even if the Company qualifies
for taxation as a REIT, the Company may be subject to certain state and local
taxes on its income and property and to federal income and excise taxes on its
undistributed income.

CYCLICALITY
 
     The Company's business, and the residential housing industry in general,
are cyclical. The Company's operations and markets are affected by local and
regional factors such as local economies, demographic demand for housing,
population growth, property taxes, energy costs, and by national factors such as
short and long-term interest rates, federal mortgage financing programs, federal
income tax provisions and general economic trends. Occupancy varies only
slightly on a seasonal basis, with the lowest occupancy typically occurring in
the summer months.
 
ENVIRONMENTAL MATTERS
 
     Under various federal, state and local laws, ordinances and regulations, an
owner of real property may be held liable for the costs of removal or
remediation of certain hazardous or toxic substances located on or in the
property. These laws often impose such liability without regard to whether the
owner knew of, or was responsible for, the presence of the hazardous or toxic
substances. The costs of any required remediation or removal of such substances
may be substantial. In addition, the owner's liability as to any property is
generally not limited under such laws, ordinances and regulations and could
exceed the value of the property and/or the aggregate assets of the owner. The
presence of such substances, or the failure to remediate such substances
properly, may also adversely affect the owner's ability to sell or rent the
property or to borrow using the property as collateral. Under such laws,
ordinances and regulations, an owner or any entity who arranges for the disposal
of hazardous or toxic substances, such as asbestos, at a disposal facility may
also be liable for the costs of any required remediation or removal of the
hazardous or toxic substances at the facility, whether or not the facility is
owned or operated by such owner or entity. In connection with the ownership of
the Properties or the disposal of hazardous or toxic substances, the Company may
be liable for such costs.
 
     The groundwater underlying portions of the City of Irvine generally
contains elevated levels of certain inorganic compounds. In addition, two United
States Marine Corps air bases where soil and groundwater contamination have been
discovered are located adjacent to the Irvine Ranch. Although the Company
believes that contamination at one of these bases is localized, there can be no
assurances that it has not migrated onto any of the Irvine Ranch Properties. The
other base is listed on the National Priorities List and activities from this
base have resulted in groundwater contamination in the vicinity of this base.
The Company has knowledge that contamination from this base has migrated into
the groundwater underlying some of the Irvine Ranch Properties. The Company
believes that most of the groundwater is located at a substantial depth under
the land surface. Since the Company believes that the Orange County Water
District together with the Department of Defense are currently conducting and
will continue to conduct remediation activities at this base and in the area,
the Company believes that it will not incur any remediation costs in connection
with the groundwater contamination.
 
     Other federal, state and local laws may impose liability for release of
asbestos containing materials (ACMs) into the air or require the removal of
damaged ACMs in the event of remodeling or renovation. There are ACMs at 11 of
the Properties, primarily in floor coverings and acoustical ceiling materials.
The Company believes that the ACMs at these properties are generally in good
condition. Comprehensive operations and maintenance plans have been implemented
for properties where ACMs are present. In addition, property custodial and
maintenance workers are trained to deal effectively with the maintenance of
existing ACMs. The Company believes it is in compliance in all material respects
with all federal, state, and local laws relating to ACMs and that there are no
regulatory requirements that currently require the removal of these ACMs;
however, if the Company were required to remove all ACMs present in its
properties over a short time frame, the cost of such removal would have a
material adverse effect on its financial condition and results of operations.
The Company also believes that ACMs are not present in the remaining Properties.
The Irvine Ranch Water District, a municipal corporation, owns and maintains
underground cement water pipes which contain asbestos and which are serving a
number of the Properties. Since these pipes are owned and maintained by the
Irvine Ranch Water District, the Company believes that any potential
environmental liabilities associated with these pipes will be incurred by the
Irvine Ranch Water District.
 
                                        9
<PAGE>   10
 
     The Company has not been notified by any governmental authority of any
material noncompliance, liability, or other claim in connection with any of the
Properties. In addition, environmental assessments (which involve physical
inspections without soil or groundwater analyses and generally without radon
testing) were obtained on all Properties in 1993 or later except for two which
were obtained more than five years ago. In addition, environmental assessments
are performed on all sites under option prior to the Company exercising its
option. The Company is not aware of any environmental liability relating to the
Properties that it believes would have a material adverse effect on its
business, assets or results of operations. Nevertheless, it is possible that the
environmental assessments did not reveal all environmental liabilities with
respect to the Properties, that environmental liabilities have developed with
respect to the Properties since the environmental assessments were prepared or
that there are material environmental liabilities of which the Company is
unaware with respect to the Properties. Moreover, no assurance can be given that
future laws, ordinances or regulations will not impose material environmental
liabilities or that the current environmental condition of the Properties will
not be affected by residents and occupants of the Properties or by the uses or
condition of properties in the vicinity of the Properties, such as leaking
underground storage tanks, or by third parties unrelated to the Company.
 
REGULATION
 
     Apartment community properties are subject to various laws, ordinances, and
regulations, including regulations relating to recreational facilities such as
swimming pools, activity centers and other common areas. The Company believes
that each property has all material permits and approvals to operate its
business. Rent control laws currently are not applicable to any of the
Properties except 1221 Ocean Avenue. However, there can be no assurance that
rent control requirements will not be initiated on additional communities in the
future.
 
     The Properties and any newly acquired or developed apartment community must
comply with Title II of the Americans with Disabilities Act (the "ADA") to the
extent that such properties are "public accommodations" and/or "commercial
facilities" as defined by the ADA. Compliance with the ADA requires removal of
structural barriers to handicapped access in certain public areas of the
Properties where such removal is "readily achievable." The ADA does not,
however, consider residential properties, such as apartment communities, to be
public accommodations or commercial facilities, except to the extent portions of
such facilities, such as a leasing office, are open to the public. The Company
believes that the Properties comply in all material respects with all present
requirements under the ADA and applicable state laws. Noncompliance with the ADA
could result in imposition of fines or an award of damages to private litigants.
 
     The Fair Housing Act (the "FHA") requires, as part of the Fair Housing
Amendments Act of 1988, apartment communities first occupied after March 13,
1990 to be accessible to the handicapped. Noncompliance with the FHA could
result in the imposition of fines or an award of damages to private litigants.
The Company believes that the Properties that are subject to the FHA are in
compliance with such law.
 
     Approximately 3,000 units in portions of 33 of the Company's Stabilized
Communities are currently subject to resident income limitations which generally
restrict rental of the affected units to low or moderate income residents and
which, in most instances, also limit the amount of rent that may be charged for
a particular unit. A brief summary of the basis and effect of these resident
income and other limitations follows:
 
     The development of 23 of the Stabilized Communities was financed with the
proceeds of tax-exempt multifamily housing revenue bonds issued by various local
municipalities. These bonds were refunded in May 1995 and consolidated under one
issuer, California Statewide Communities Development Authority. Regulatory
agreements applicable to such financings (a) require that a specified percentage
of the units be set aside for residents whose incomes do not exceed a specified
percentage of the area median income and (b) in most instances, limit the rent
which can be charged to a percentage of the maximum qualifying resident income
level for the affected unit. These bonds were refinanced in June 1998 by the
same issuer. Most of the income restrictions on the new bonds will terminate
upon the maturity date of the new bonds. Additionally, in October 1998, the
Company purchased a 216-unit apartment community (One Park Place) for $28
million of which $18 million was the assumption of tax-exempt multifamily
housing revenue bonds.
 
                                       10
<PAGE>   11
 
     In addition to the rental restrictions imposed by the bond regulatory
agreements, many of the 24 properties and four additional properties are also
subject to resident income and rent limitations by virtue of development and
other agreements entered into with local municipalities and private and
quasi-public interest groups. These restrictions are similar in scope and
substance to the other restrictions discussed above.
 
     Five of the Stabilized Communities were developed with the assistance of
U.S. Department of Housing and Urban Development ("HUD") administered programs
which provided mortgage insurance to the project lender. Certain regulatory and
other agreements with HUD applicable to such financings (a) impose resident
income restrictions similar to those imposed by the bond financing agreements,
and (b) generally require the Company to operate the Properties in accordance
with HUD's standards. With respect to one of the properties (i.e., The
Parklands), a regulatory agreement additionally (a) limits the distribution of
income from the property to 10% of the HUD imputed equity in the property and
(b) requires that any income in excess of such 10% limit be deposited into a
residual receipts account. Amounts paid into such residual receipts account have
historically been used for capital improvements to the property, subject to
HUD's consent. At the expiration of the applicable regulatory or other
agreement, any amount remaining in such residual receipts account belongs to
HUD.
 
     Under Section 8 of the United States Housing Act of 1937, HUD currently
provides rental assistance payments to each of these five HUD properties
pursuant to certain Housing Assistance Payments ("HAP") contracts. Under the HAP
contracts, so long as the units are rented to residents whose income levels do
not exceed specified HUD guidelines, each qualifying resident is required to pay
only 30% of their adjusted monthly income as rent and HUD pays the difference
between the 30% payment and the unit's market rents as established by HUD. The
above-mentioned restrictions and limitations will continue for the remainder of
each HAP contract term. Each HAP contract has an initial term of 20 years with
four 5-year renewal options exercisable at the owners option. At December 31,
1998, the average remaining term of the HAP contracts was approximately 4 years.
 
     Each of the resident and income restricted units within the Company's
portfolio has been subject to one or more of the foregoing restrictions either
since their initial occupancy or as a result of subsequent agreements with the
applicable governmental authority or other private or quasi-public interest
groups. Accordingly, the effect of these restrictions on rental income from the
Properties has been reflected in the historical financial results of the
Company.
 
     The Company believes that it is in material compliance with all of the
foregoing requirements. The failure of the Company to comply with the terms of
any of the foregoing could adversely affect the Company's operations.
 
     The Company may purchase land in the future, which as a condition of
purchase has the inclusion of units at below market rental rates. Construction
of such properties may be financed with tax-exempt debt. In any case, the
Company will evaluate the economics inclusive of any rental restriction and
benefit of below-market, tax-exempt financing prior to purchasing the land.
 
FACTORS RELATING TO REAL ESTATE OPERATIONS AND DEVELOPMENT
 
     General: Real property investments are subject to varying degrees of risk.
The investment returns available from equity investments in real estate depend
in large part on the amount of income earned and capital appreciation generated
by the related properties as well as the expenses incurred. If the Properties do
not generate revenue sufficient to meet operating expenses, including debt
service and capital expenditures, the Company's income and ability to service
its debt and other obligations and to make distributions to its
shareholders/partners will be adversely affected. In addition, the Properties
consist primarily of rental apartment communities geographically concentrated in
Orange County. Income from and the performance of the Irvine Ranch Properties
may therefore be adversely affected by the general economic climate in Orange
County, including unemployment rates and local conditions such as the supply of
and demand for apartments in the area, the attractiveness of the Irvine Ranch
Properties to residents, zoning or other regulatory restrictions, competition
from other available apartments and alternative forms of housing, the
affordability of single family homes, the ability of the Company to provide
adequate maintenance and insurance and the
                                       11
<PAGE>   12
 
potential of increased operating costs (including real estate taxes). Certain
significant expenditures associated with an investment in real estate (such as
mortgage and other debt payments, real estate taxes and maintenance costs)
generally are not reduced when circumstances cause a reduction in revenue from
the investment. In addition, income from properties and real estate values are
also affected by a variety of other factors, such as governmental regulations
and applicable laws (including real estate, zoning and tax laws), interest rate
levels and the availability of financing. The Irvine Ranch Properties in the
aggregate historically have generated positive cash flow from operations;
however, no assurance can be given that such will be the case in the future.
 
     The Company's "off-Ranch" expansion program was initially centered in
Northern California's Silicon Valley and the northern coastal markets of San
Diego County. In 1997, the Company acquired a 923-unit apartment community (The
Villas of Renaissance) located in the La Jolla region of Northern San Diego
County. In 1998, the Company completed construction of a 342-unit apartment
community (The Hamptons at Cupertino) in the Silicon Valley and began
construction on three additional apartment communities (with a total of
approximately 660 units) in the Silicon Valley and two additional apartment
communities (with a total of approximately 560 units) in Northern San Diego
County. Also in 1998, the Company purchased a 119-unit, high-rise apartment
building under renovation located in Santa Monica (1221 Ocean Avenue). These new
Properties represent the Company's first strategic expansion off the Irvine
Ranch and the Company may make additional investments in California in the
future. The development, construction and operation of rental apartment
communities in such new markets may present risks different than or in addition
to the risks discussed above related to the Irvine Ranch Properties which are
located entirely in Orange County. For jurisdictions off the Irvine Ranch, local
jurisdiction approvals with respect to entitlements may impose requirements and
conditions different from those applicable to the Irvine Ranch. No assurance can
be given that the Company will be successful in pursuing any additional
"off-Ranch" expansion or that any "off-Ranch" apartment communities will be
successful.
 
     Equity real estate investments, such as the investments made by the Company
in the Properties and any additional properties that may be developed or
acquired by the Company, are relatively illiquid. Such illiquidity limits the
ability of the Company to vary its portfolio in response to changes in economic
or other conditions. In addition, the Internal Revenue Code places limits on the
Company's ability to sell properties held for fewer than four years, which may
affect the ability of the Company to sell properties without adversely affecting
returns to holders of common stock.
 
     The Properties are subject to all operating risks common to apartment
ownership in general. Such risks include: the Company's ability to rent units at
the Properties, including the 3,503 units in the Communities Under Development;
competition from other apartment communities; excessive building of comparable
properties which might adversely affect apartment occupancy or rental rates;
increases in operating costs due to inflation and other factors which increases
may not necessarily be offset by increased rents; increased affordable housing
requirements that might adversely affect rental rates; inability or
unwillingness of residents to pay rent increases; and future enactment of rent
control laws or other laws regulating apartment housing, including present and
possible future laws relating to access by disabled persons. If operating
expenses increase, the local rental market may limit the extent to which rents
may be increased to meet increased expenses without decreasing occupancy rates.
If any of the above occurred, the Company's ability to meet its debt service and
other obligations and to make distributions with respect to its common stock and
the partnership interests of the Operating Partnership could be adversely
affected.
 
     Real Estate Development and Acquisition: A primary focus of the Company is
the development of new apartment communities on sites acquired or that may be
acquired in the future, primarily from The Irvine Company, although the Company
also plans to develop new rental apartment communities on sites acquired or that
may be acquired in the future from third parties. The Company has also acquired,
and may continue to acquire, completed communities. The real estate development
business involves significant risks in addition to those involved in the
ownership and operation of established apartment communities, including the
risks that specific project approvals may take more time and resources to obtain
than expected, that construction may not be completed on schedule or budget and
the properties may not achieve anticipated rent or occupancy levels. In
addition, if long-term debt or equity financing is not available on acceptable
terms to finance new
                                       12
<PAGE>   13
 
development or acquisitions undertaken without long-term financing, further
development activities or acquisitions might be curtailed or cash available for
debt service and other obligations might be adversely affected.
 
     The development of apartment communities both on and off the Irvine Ranch,
requires the investment of funds, sometimes in substantial amounts, prior to the
completion of necessary due diligence and/or the receipt of necessary
entitlements for the acquisition of a land site or an apartment community. In
addition, the Company has entered into an agreement giving it the right, but not
the obligation, to acquire a land site in Northern California for the
development of over 2,000 apartment units, subject to the receipt of necessary
entitlements. If such entitlements are not obtained, or if for any reason any
projects are abandoned, the associated costs would be expensed. While the
Operating Partnership seeks to mitigate such risk and has not written off
significant amounts to date, no assurance can be given that it will not be
required to do so in the future.
 
     Insurance: The Company carries comprehensive liability, fire, extended
coverage and rental loss insurance covering all of the Properties, with policy
specifications and insured limits which the Company believes are adequate and
appropriate under the circumstances. There are, however, certain types of losses
(such as from earthquakes) that are not generally insured because they are
either uninsurable or not economically insurable. The Company does not carry
earthquake insurance on any of the Properties. Should an uninsured loss or a
loss in excess of insured limits occur, the Company could lose its capital
invested in the property, as well as the anticipated future revenues from the
property, and, in the case of debt which is recourse to the Company, would
remain obligated for any mortgage debt or other financial obligations related to
the property. Any such loss would adversely affect the Company. The Company
believes that the Properties are adequately insured. In addition, in light of
the California earthquake risk, California building codes since the early 1970's
have established construction standards for all newly built and renovated
buildings, including apartment buildings, the current and strictest construction
standards having been adopted in 1984. Thirty-six of the existing 55 Stabilized
Communities (representing approximately 71% of the units in the Communities)
have been completed and occupied since January 1, 1985, and the Company believes
that all of the Stabilized Communities were constructed, and all of the
Communities Under Development are being constructed, in full compliance with the
applicable standards existing at the time of construction. While earthquakes
have occurred from time to time in California, the Company has not experienced
any material losses as a result of earthquakes. No assurance can be given that
this will be the case in the future.

ITEM 3. LEGAL PROCEEDINGS
 
     Shortly after the public announcement of TIC Acquisition LLC's offer to
acquire the outstanding publicly held shares of the Company, certain lawsuits
were initiated by shareholders of the Company against The Irvine Company, TIC
Acquisition LLC, the Company and the Company's Directors alleging, among other
things, that the price offered by TIC Acquisition LLC for the shares held by the
public shareholders of the Company was inadequate, that the Directors failed to
take adequate steps to obtain the highest possible price for the public
shareholders of the Company and that negotiations were not conducted at
arm's-length. As of February 16, 1999, four purported class actions relating to
this acquisition offer had been served; each of these actions was filed in the
Superior Court of California, Orange County, on behalf of a plaintiff
shareholder of the Company and a purported class of all public shareholders of
the Company. These lawsuits seek injunctive relief and unspecified money
damages.
 
     On December 29, 1998, the four pending actions and all actions subsequently
filed in, removed to, or transferred to the Superior Court of California for
Orange County were consolidated.
 
     All of the Company defendants intend vigorously to defend against
plaintiffs' claims. The likelihood of an unfavorable outcome cannot be predicted
at this time.
 
     None of the Company, the Operating Partnership, the Trust nor the
Properties are subject to any other material litigation.

     The merger agreement relating to the proposed merger of the Company with
TIC Acquisition LLC permits the continued declaration and payment of regular
quarterly dividends of $.385 per share on the Company's common stock, in
accordance with past practice, but also requires that the record dates for the
second and third quarter 1999 quarterly dividends not be earlier than June 15,
1999 and September 15, 1999, respectively. Such dates are later than the record
dates in prior years. The Company currently intends to set the close of business
on June 15, 1999 as the record date for the second quarter 1999 quarterly
dividend. Therefore, if the merger is consummated on or before June 15, 1999,
additional dividends will not be paid on the Company's common stock. The Company
cannot predict what dividends, if any, with respect to the membership interests
of TIC Acquisition LLC will be paid following the merger, if it is consummated.
 
     If the merger is not consummated, the Company intends to continue to pay
regular quarterly dividends on the Company's common stock.
 
IRVINE APARTMENT COMMUNITIES, L.P.
 
     There is no established public trading market for the Operating
Partnership's common partnership interests. As of February 10, 1999, there were
ten (including the general partner interest) holders of common partnership
interests.
 
     The table set forth under Irvine Apartment Communities, Inc. regarding
dividends and return of capital is equally applicable on a per unit basis to the
Operating Partnership as to the Company.
 
     The merger agreement relating to the proposed merger of the Company with
TIC Acquisition LLC permits the continued declaration and payment of regular
quarterly distributions on the common partnership interests of the Operating
Partnership. The Company anticipates that any future distributions, if any, on
common partnership interests of the Operating Partnership will be paid in
conjunction with dividends on the Company's common stock. The Company cannot
predict what distributions, if any, with respect to the common partnership
interests of the Operating Partnership will be paid following the merger, if it
is consummated.
 
     If the merger is not consummated, the Company intends to continue to pay
regular quarterly distributions on the common partnership interests of the
Operating Partnership.
 
     During the fourth quarter of 1998, the Operating Partnership sold 2,000,000
Series B Preferred L.P. Units in the Operating Partnership to Greene Street 1998
Exchange Fund, L.P. for aggregate consideration of $50,000,000 (less a
$1,250,000 placement fee) pursuant to exemptions provided by Section 4(2) of the
Securities Act of 1933. Each Series B Preferred L.P. Unit is exchangeable under
certain circumstances into preferred stock of the Company or preferred
securities of the Trust.
 
     There were no issuances of common limited partnership interests in the
Operating Partnership during the fourth quarter of 1998.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
     The following discussion should be read in conjunction with the Selected
Financial Data, the Consolidated Financial Statements of the Company, the
Operating Partnership and the Trust and the Notes thereto.
 
OVERVIEW
 
     Irvine Apartment Communities, Inc. (the "Company"), a Maryland corporation,
operates as a real estate investment trust ("REIT") under the Internal Revenue
Code of 1986, as amended. At December 31, 1998, the Company had a 44.6% general
partnership interest in and was the sole managing general partner of Irvine
Apartment Communities, L.P. (the "Operating Partnership") which began operations
as of December 8, 1993, the date of the Company's initial public offering of
common stock. At December 31, 1998, the limited partners had a 55.4% limited
partnership interest in the Operating Partnership, with The Irvine Company and
certain of its affiliates owning a 55.2% common limited partnership interest in
the Operating Partnership. In addition, at December 31, 1998, The Irvine Company
and its affiliates owned approximately 17.9% of the common shares of the
Company.
 
     The Company is a self-administered equity REIT engaged in the operation and
development of apartment communities in California. The Company's strategic
growth plan is designed to create new market positions in California which
possess rental demographics and economic growth prospects similar to those on
the Irvine Ranch. As of December 31, 1998, the Operating Partnership owned and
operated 65 properties containing 16,439 apartment units and had 3,039 units
under construction or development. In March 1998, the Operating Partnership and
Western National Property Management ("WNPM") announced the formation of a
strategic alliance that, in April 1998, assumed all property management
responsibilities for the Operating Partnership's Southern California portfolio.
The new entity, Irvine Apartment Management Company ("IAMC"), is owned 51% by
the Operating Partnership and 49% by WNPM. Until July 31, 2020, the Company and
the Operating Partnership have the exclusive right, but not the obligation, to
acquire land from The Irvine Company for development of additional apartment
communities on the Irvine Ranch.
 
     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 Company and the Operating Partnership. The Trust exists for the sole
purpose of issuing preferred securities and investing the proceeds thereof in
preferred limited partner units of the Operating Partnership. In January 1998,
the Trust issued 6.0 million of its 8 1/4% Series A Preferred Securities
resulting in gross proceeds of $150 million.
 
  Going Private Transaction
 
     On February 1, 1999, the Company and TIC Acquisition LLC, an indirect
wholly owned subsidiary of The Irvine Company, entered into a definitive merger
agreement providing for a merger of the Company into TIC Acquisition LLC in
which the Company's shareholders will receive $34 in cash per share. The
transaction, which is subject to the approval of the holders of (i) at least
two-thirds of the outstanding shares of common stock of the Company and (ii) a
number of shares of common stock of the Company (excluding the shares held by
TIC Acquisition LLC and its affiliates) representing a majority of the total
number of shares of common stock of the Company entitled to vote, and other
customary conditions, is expected to be completed late in the second quarter or
early in the third quarter of 1999.
 
RESULTS OF OPERATIONS
 
     The Company's income before extraordinary item, minority redeemable
preferred interests and minority interest in income was $73.5 million in 1998,
up from $58.6 million in 1997 and $41.2 million in 1996. The Company's financial
results improved in 1998 due to the contribution of newly delivered rental units
from its development program, properties that stabilized during 1997, an
increase in rental rates within its stabilized portfolio, and an acquisition in
1998, partially offset by a slight decrease in physical occupancy and an
increase in minority redeemable preferred interests due to the issuance of
preferred securities in January and November 1998. In 1997, financial results
improved due to the contribution of newly delivered rental units
 
                                       22

from its development program, an acquisition in 1997 and an increase in rental
rates within its stabilized portfolio.

(1) Represents 43 communities (11,334 units) that achieved stabilized occupancy
    (95%) prior to 1996 and 5 communities (2,207 units) that achieved stabilized
    occupancy in 1996. No comparison for 1997 and 1996 is shown since not all of
    the properties were stabilized for comparable periods.
 
(2) Represents two communities (527 units) that achieved stabilized occupancy
    during 1997. No year-over-year comparison is provided since the properties
    were not stabilized for comparable periods.
 
(3) Represents three properties (768 units) that achieved stabilized occupancy
    at various dates in 1998, the Villas of Renaissance apartment community (923
    units) purchased on June 30, 1997, One Park Place apartment community (216
    units) purchased on October 8, 1998, and two apartment communities in
    lease-up at December 31, 1998.
 
     OPERATING REVENUES (rental and other income) increased by 17.9% to $219.4
million in 1998, up from $186.1 million in 1997. Operating revenues in 1997 had
increased by 17.7% from $158.1 million in 1996. Operating revenues rose in 1998
because of higher rental rates and a larger average number of rental units in
service, primarily as a result of new development. Newly delivered and acquired
units along with unit growth in the Company's portfolio stabilized less than two
years added $38.2 million to operating revenues from nine properties in 1998,
compared to $13.5 million from six properties in 1997. Operating revenues
generated by communities stabilized more than two years increased 5.0% in 1998
due to an improvement in the portfolio's average rental rate, partially offset
by a decrease in average physical occupancy to 94.3% from 94.6%. The average
monthly rental rate for these communities increased 5.2% to $1,165 in 1998, from
$1,107 in 1997.
 
                                       23
<PAGE>   24
 
     Operating revenues rose in 1997 because of higher rental rates and a larger
average number of rental units in service as a result of both new development
and an acquisition in June 1997. Newly delivered, acquired and stabilized units
added $45.5 million to operating revenues in 1997 from eleven properties,
compared to $24.7 million in 1996 from five properties. Operating revenues
generated by communities owned and stabilized more than two years increased 5.5%
in 1997, due to an improvement in the average monthly rental rate, partially
offset by a decrease in average physical occupancy to 94.6% from 95.0%. The
average monthly rental rate for these communities increased 6.2% to $1,078 in
1997, from $1,015 in 1996.
 
     PROPERTY EXPENSES increased by 10.8% to $49.4 million in 1998 from $44.6
million in 1997, which had increased from $38.4 million in 1996. The 1998
increase reflects incremental expenses from newly delivered and acquired rental
units and communities stabilized during 1997. Property expenses for communities
stabilized more than two years decreased by $0.2 million to $41.1 million in
1998. Average monthly property expenses generated by these communities decreased
to $253 per unit in 1998 from $254 per unit in 1997. Newly delivered and
acquired units and communities stabilized less than two years added $8.3 million
to property expenses from nine properties in 1998 compared to $3.2 million from
six properties in 1997. To improve operating efficiency and reduce operating
costs, the Company formed IAMC to manage the Company's properties in April 1998.
Accordingly, the personnel and office costs of IAMC are included in 1998
property expenses. For comparative purposes, prior period management fees have
been included in property expenses.
 
     The 1997 increase primarily reflects the added expenses from the newly
delivered and acquired rental units and communities stabilized less than two
years. Property expenses for communities owned and stabilized more than two
years increased by $3.0 million to $41.3 million from $38.3 million in 1996.
Average monthly property expenses generated by these communities increased to
$254 per unit in 1997 from $236 per unit in 1996, primarily as a result of five
communities that stabilized during 1996, as well as higher insurance expenses,
higher unit turnover and related expenses, and preventative maintenance
scheduled in anticipation of an unseasonably wet winter. Lease-up and newly
acquired properties added $3.2 million in 1997.
 
     REAL ESTATE TAXES totaled $17.2 million in 1998, $15.0 million in 1997 and
$13.5 million in 1996. Real estate taxes increased in 1998 and 1997 primarily
due to the addition of new rental units.
 
     NET INTEREST EXPENSE decreased to $27.8 million in 1998 from $30.4 million
in 1997, which had increased from $29.5 million in 1996. Total interest incurred
was $40.1 in 1998 compared with $36.1 million in 1997 and $32.7 million in 1996.
The increase in interest incurred in 1998 was primarily due to unsecured notes
payable that were outstanding for the entire period, partially offset by lower
interest rates in 1998. Net interest expense declined in 1998 because the
Company's increased level of development resulted in a higher level of
capitalized interest. Net interest expense rose in 1997 largely due to a greater
level of borrowing under the credit facility, which was used to finance an
acquisition in June 1997. The Company capitalizes interest on projects actively
under development using qualifying asset balances and applicable weighted
average interest rates. Capitalized interest totaled $12.3 million in 1998, $5.7
million in 1997 and $3.2 million in 1996.
 
     INTEREST INCOME totaled $1.5 million in 1998, $0.8 million in 1997 and $0.6
million in 1996. The changes in interest income reflect changes in the Company's
average cash balances.
 
     AMORTIZATION OF DEFERRED FINANCING COSTS decreased by 20.8% to $1.9 million
in 1998 from $2.4 million in 1997, which was down from $2.6 million in 1996. The
$0.5 million decrease in 1998 was due to the full amortization of certain loan
costs during the prior year and a lower level of deferred financing costs
associated with the unsecured tax-exempt bond financings. The $0.2 million
decrease in 1997 was due to the full amortization of certain loan costs during
that year.
 
     DEPRECIATION AND AMORTIZATION EXPENSE increased by 15.4% to $33.8 million
in 1998, up from $29.3 million in 1997. These expenses had increased in 1997 by
7.7% from $27.2 million in 1996. The increases in both years reflect the
completion and delivery of newly developed rental units. In addition, the 1998
amount reflects three months of depreciation from One Park Place, a community
acquired in 1998, and the 1997 amount reflects six months of depreciation from
The Villas of Renaissance, a community acquired in 1997.

     GENERAL AND ADMINISTRATIVE EXPENSE increased by 40.3% to $9.4 million in
1998, up from $6.7 million in 1997 and $6.3 million in 1996. The increase in
1998 was largely the result of $1.0 million of costs related to The Irvine
Company's acquisition offer, increased salary expenses due to a new chief
executive officer, $453,000 of project abandonment expenses and increased staff
levels necessitated by the Company's growth. The increase in 1997 was largely
the result of increased staff levels necessitated by the Company's growth.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company believes that cash provided by operations will be adequate to
meet both operating requirements and payment of distributions by the Company in
accordance with REIT requirements in both the short and long term.
 
     LIQUIDITY: The Company expects to meet its short-term and long-term
liquidity requirements, such as construction costs, scheduled debt maturities
and potential future property acquisitions, through the issuance or refinancing
of long-term debt, borrowings from financial institutions, or the issuance of
additional equity securities of the Company, partnership units by the Operating
Partnership or preferred securities by the Trust. The Operating Partnership has
a $250 million unsecured revolving credit facility that was amended in July
1998. The amended 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 Operating
Partnership's senior unsecured long-term indebtedness. In January 1998, all
outstanding borrowings under the credit facility were repaid from the proceeds
of the offering by the Trust of its 8 1/4% Series A Preferred Securities. In
1998, the Company entered into letters of credit under the credit facility
totaling $29.1 million related to land and building purchases (see "Capital
Investments in New Development"). The letters of credit reduced the remaining
amount available under the line of credit. Availability under the credit
facility was $220.9 million at December 31, 1998.
 
     SHELF REGISTRATION STATEMENTS: On May 14, 1997, the Company filed a shelf
registration statement with the Securities and Exchange Commission providing for
the issuance from time to time of up to $350 million of common stock, preferred
stock, and warrants to purchase common stock and preferred stock. The Company
plans to use the proceeds raised from any securities issued under its shelf
registration statement for general corporate purposes, including the development
of new apartment communities, acquisitions and the repayment of existing debt.
Availability under the Company's shelf registration statement was $350 million
at December 31, 1998. Concurrently, the Operating Partnership filed a shelf
registration statement with the Securities and Exchange Commission providing for
the issuance from time to time of up to $350 million of debt securities. The
Operating Partnership plans to use the proceeds raised from any securities
issued under its shelf registration statement for general corporate purposes,
including the development of new apartment communities, acquisitions and the
repayment of existing debt. On October 1, 1997, the Operating Partnership issued
$100 million aggregate principal amount of 7% senior unsecured notes pursuant to
its shelf registration statement. Availability under the Operating Partnership's
shelf registration statement was $250 million at December 31, 1998. The
Operating Partnership, pursuant to a Prospectus Supplement dated April 9, 1998,
may issue from time to time up to $250 million aggregate initial offering price
of its Medium-Term Notes, Series A due nine months or more from the date of
issue. Issuances of medium-term notes will reduce availability under the
Operating Partnership's shelf registration statement by the amount of
medium-term notes issued. Similarly, issuances of other debt securities under
the Operating Partnership's shelf registration statement will reduce the amount
of medium-term notes that may be issued. As of December 31, 1998, there have
been no issuances of medium-term notes.
 
     IAC CAPITAL TRUST: The Trust was formed on October 31, 1997. The Trust is a
limited purpose financing vehicle established by the Company and the Operating
Partnership. The Trust exists for the sole purpose of issuing its preferred
securities and investing the proceeds thereof in preferred limited partner units
of the Operating Partnership. In January 1998, the Trust issued 6.0 million of
its 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 Operating Partnership. The Operating Partnership used the $150
million of proceeds, net of costs and expenses, all of which were paid by the
Operating Partnership, to repay outstanding borrowings under the credit facility
and to fund development and an acquisition.
                                       25
<PAGE>   26
 
     DEBT: The Company's conventional and tax-exempt debt bears interest at
fixed interest rates. Interest rates on conventional mortgage debt were reduced
to then-current market rates at the time of the Company's December 1993 initial
public offering through interest rate buy-down agreements that are scheduled to
expire at various dates prior to loan maturity that range from 2000 to 2008. The
weighted average effective interest rate on the Company's debt, including the
non-cash charges of amortization of deferred financing costs, was 6.03% at
December 31, 1998. In June 1998, the Company 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 Company's existing tax-exempt mortgage debt and to pay a portion of
the costs associated with prepayment penalties and the unwinding of certain swap
agreements.

     OPERATING ACTIVITIES: Cash provided by operating activities was $83.8
million, $94.7 million and $73.0 million for 1998, 1997 and 1996, respectively.
Cash provided by operating activities decreased in 1998 compared to 1997 due to
an extraordinary item related to debt extinguishment, partially offset by higher
revenues from newly developed and acquired apartment units, as well as an
increase in revenues within the Company's stabilized portfolio achieved through
higher rental rates.
 
     INVESTING ACTIVITIES: Cash used in investing activities was $231.7 million,
$249.6 million and $66.6 million in 1998, 1997 and 1996, respectively. Changes
in the amount of cash used in investing activities in each year reflect changing
levels of real estate development and acquisitions in 1998 and 1997. Real estate
development and acquisitions are typically funded by the line of credit until
long-term financing is obtained (see "Financing Activities and Capital
Expenditures").
 
     FINANCING ACTIVITIES: Cash provided by (used in) financing activities was
$148.2 million, $156.3 million, and $(7.6) million in 1998, 1997 and 1996,
respectively. The Operating Partnership received net proceeds of $192.7 million
from the sale of preferred limited partner units in January and November of
1998, a portion of which was used to pay down the Operating Partnership's line
of credit. Additionally, the Operating Partnership received a $100 million
unsecured term loan with which it paid down the Operating Partnership's line of
credit. The Company and the Operating Partnership received $66 million from the
issuance of common stock and partnership units in 1997. These proceeds were used
to pay down borrowings under the line of credit. In June 1997, $118 million was
borrowed under the line of credit to fund the acquisition of The Villas of
Renaissance. In October 1997, the Operating Partnership received net proceeds of
$97.9 million from the issuance of the 7% Notes. These proceeds were used to
repay outstanding borrowings under the line of credit. Additionally, the Company
paid $80.7 million in distributions to common shareholders, common limited
partners and minority redeemable preferred interests holders in 1998 compared to
$64.1 million in 1997 and

$56.1 million in 1996. Among the factors affecting cash in 1996, the Company
received $60.0 million from the sale of common stock and partnership units.
These proceeds were used to repay borrowings under the line of credit.
 
CAPITAL EXPENDITURES
 
     Capital expenditures consist of capital improvements and investments in
real estate assets. Capital improvements to operating real estate assets totaled
$5.9 million, $5.0 million and $4.8 million in 1998, 1997 and 1996,
respectively. Capital investments in real estate assets totaled $226 million,
$245 million and $62 million in 1998, 1997 and 1996, respectively, and consisted
of capital investments in new developments, nonrecurring capital replacements,
acquisitions of apartment communities and land purchases.

     RECURRING CAPITAL IMPROVEMENTS WITHIN COMMUNITIES STABILIZED BEFORE
1997. Expenditures for recurring capital improvements within communities
stabilized before 1997 totaled $5.7 million, $5.0 million and $4.8 million in
1998, 1997 and 1996, respectively. Average recurring capital improvements per
unit were $418, $372 and $353 in 1998, 1997 and 1996, respectively. The Company
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. Expenditures for recurring capital
improvements in 1999 are expected to be similar to 1998 levels.
 
     RECURRING CAPITAL IMPROVEMENTS WITHIN COMMUNITIES STABILIZED IN OR AFTER
1997. Expenditures for recurring capital improvements within communities
stabilized in or after 1997 totaled $0.2 million.
 
     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 $6.8
million in 1998. These expenditures were made at two properties, Promontory
Point and The Villas of Renaissance. Expenditures for nonrecurring capital
replacements are expected to be approximately $9 million in 1999.
 
     CAPITAL INVESTMENTS IN NEW DEVELOPMENT: The major cash requirements in 1999
are expected to be for the construction of new apartment communities and
possible acquisitions of apartment communities. Currently, the Company has nine
apartment communities under development or construction that will require total
expenditures of approximately $570 million, of which $212 million had been
incurred at December 31, 1998. Funding for these developments is expected to
come from the Operating Partnership's $250 million unsecured revolving credit
facility (of which $220.9 million was available as of December 31, 1998), debt
offerings of the Operating Partnership and preferred securities offerings of the
Trust. In addition, the Company may issue other equity securities as discussed
in the Liquidity section.

</TABLE>
 
     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 Company. These include the extent and timing of economic growth
in the Company's rental markets; future trends in the pricing of construction
materials and labor; 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.
 
YEAR 2000
 
     GENERAL: As is the case with many computer and microprocessor-based
systems, certain of the Company's systems use two digit date fields which
recognize dates using the assumption that the first two digits are "19" (i.e.,
the number "98" is recognized as the year "1998"). Because of the nature of its
operations, the Company does not believe that its business, results of
operations or financial condition will be materially adversely affected by a
failure of these systems. Nonetheless, the Company has initiated a plan to
assess (and remediate, as necessary) its computer and microprocessor-based
systems.
 
     STATE OF YEAR 2000 READINESS: The Company's Year 2000 project is divided
into four general exposure types -- infrastructure, 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 Company; (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 and applications software sections consist of hardware
and systems software. As of December 31, 1998, all infrastructure has been
repaired or replaced and is believed to be Year 2000 compliant. As of December
31, 1998, approximately 90% of the Company's applications software had been
confirmed to be Year 2000 compliant. The Company expects to complete the
remaining assessment and repair or replacement, including testing, during the
second quarter of 1999.
 
                                       28
<PAGE>   29
 
     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 Company's third
parties is based primarily on representations from such parties. The Company has
queried 100% of its significant suppliers and subcontractors that do not share
information systems with the Company. Follow-up inquiries are scheduled through
the remainder of 1999, at which time the Company will implement contingency
plans or other alternatives, as necessary, depending on the third parties' Year
2000 readiness. To date, the Company is not aware of any third parties with a
Year 2000 issue that would materially impact the Company's results of
operations, liquidity, or capital resources. However, the Company has no means
of ensuring that third parties will be Year 2000 ready.
 
     Plans detailing the tasks and resources required for the PC&I section are
in place. This section includes the hardware, software and associated embedded
computer chips that are used in the operation of all facilities operated by the
Company. PC&I equipment includes security systems, lighting systems, HVAC
systems and sprinkler systems. As of December 31, 1998, the Company had assessed
the Year 2000 readiness in approximately 90% of its PC&I systems. The Company
believes that the repair or replacement and testing of PC&I equipment is
approximately 25% complete. The Company expects to complete the repair or
replacement of its PC&I systems by the second quarter of 1999, with all testing
scheduled to be completed by year-end 1999.
 
     COSTS: The Company has incurred less than $50,000 in connection with its
Year 2000 remediation efforts. The Company estimates its future costs related to
its Year 2000 remediation efforts to be less than $50,000. Overall, the Company
does not expect its Year 2000 expenditures to be material to the Company's
business, results of operations or financial condition.
 
     RISK AND CONTINGENCY PLANNING: Management of the Company believes it has a
program in place to adequately resolve the Year 2000 issue in a timely manner.
As noted above, the Company has not yet completed all necessary resolution
phases of the Year 2000 project. Although there can be no assurance, the Company
does not believe that a Year 2000 failure of any of its internal software or
hardware systems would have 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 Company's operations. For example, a Year
2000 failure by one or more of the financial institutions or utility companies
with which the Company does business could cause the Company to lose access to
its funds or could restrict the Company'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 Company's ability to pay interest on
its bonds or to pay dividends or distributions on its equity securities. The
Company currently has no contingency plans in place in the event it does not
complete all resolution phases of the Year 2000 project. The Company plans to
periodically evaluate the status of completion and determine whether such a plan
is necessary.
 
     The Company's assessment of its risks, and its expectations as to future
Year 2000 compliance, are forward-looking statements.
 
IMPACT OF INFLATION
 
     The Company's business is affected by general economic conditions,
including the impact of inflation and interest rates. Substantially all of the
Company's leases allow, at time of renewal, for adjustments in the rent payable
thereunder, and thus may enable the Company 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 Company of
the adverse effects of inflation. For construction, the Company has entered into
various contracts for the development and construction of new apartment
communities. These are fixed-fee contracts and thus partially insulate the
Company from inflationary risk.
 
FUNDS FROM OPERATIONS
 
     The Company generally considers funds from operations ("FFO") a useful
measure of performance for an equity REIT. The Company computes FFO in
accordance with standards established by the National Association of Real Estate
Investment Trusts ("NAREIT"). FFO is defined as net income (computed in
                                       29
<PAGE>   30
 
accordance with generally accepted accounting principles), excluding gains or
losses from debt restructuring and sales of property, plus depreciation and
amortization of real estate assets, and after adjustments for unconsolidated
partnerships and joint ventures. Other REITs may not use this definition of FFO.
FFO should be considered in conjunction with net income as presented in the
Company's Consolidated Financial Statements and Notes thereto. FFO should not be
considered an alternative to net income as an indication of the Company's
performance and is not indicative of cash available to fund all cash flow needs.
FFO does not represent cash flows from operating, investing, or financing
activities as defined by generally accepted accounting principles.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
     The Company's exposure to market risk for changes in interest rates relates
primarily to the Company's current and future debt obligations. The Company's
philosophy is to maintain a fairly low tolerance to interest rate fluctuation
risk. The Company is still vulnerable, however, to significant fluctuations of
interest rates on its floating rate debt, repricing on its fixed rate debt at
various points in the future and future debt.
 
     The following table provides information about the Company's derivative
financial instruments and other financial instruments that are sensitive to
changes in interest rates. For debt obligations, the table presents principal
cash flows and related weighted-average interest rates by expected maturity
dates. For the interest rate swap, the table presents notional amounts and
weighted-average interest rates by contractual maturity dates. Notional amounts
are used to calculate the contractual cash flows to be exchanged under the
contract.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Messrs. McCoy and Seymour served on the Compensation Committee during 1998.
No Compensation Committee interlocks or insider participation existed in 1998.
 
COMPENSATION OF DIRECTORS
 
     The Company pays its Directors who are neither officers of the Company nor
officers or directors of The Irvine Company ("Outside Directors") fees for their
services as directors. Directors receive annual compensation of $30,000 plus a
fee of $1,500 for attendance (in person or by telephone) at each meeting of the
Board of Directors, plus a fee of $750 for attendance (in person or by
telephone) at each meeting of a committee of the Board of Directors, whether or
not such committee meeting occurs on the same day as a meeting of the Board of
Directors, plus annual compensation of $3,000 for acting as chairperson of a
standing committee of the Board of Directors. Outside Directors will be able to
defer their annual retainer fee in accordance with the Company's 1998 Deferred
Compensation Plan for Outside Directors. The Company also has established the
1993 Stock Option Plan for Directors, as amended, pursuant to which each
Eligible Director, as defined below, is (1) awarded an option to purchase 5,000
shares of the Company's Common Stock upon initial appointment or election to the
Board and (2) awarded an option to purchase 2,500 shares of the Company's Common
Stock at each subsequent annual meeting, except for Eligible Directors as
defined in the 1993 Stock Option Plan for Directors first elected to the Board
within the twelve months immediately preceding and including such meeting. The
exercise price of any such option is equal to the fair market value of the
Common Stock on the date of grant. Such options are exercisable at all times
during the period beginning on the date of grant and ending on the earlier of
(i) the tenth anniversary of the date of grant or (ii) the first anniversary of
the date on which the optionee ceases to be an Eligible Director. For purposes
of the Plan, "Eligible Director" means any Director who: (i) is not an employee
of the Company or any of its subsidiaries or affiliates, (ii) is unaffiliated
with The Irvine Company and Mr. Bren and has not been employed by The Irvine
Company within the preceding five years and (iii) has not received a stock award
within the preceding year under an employee stock plan of the Company.
 
     In addition to the Company's normal fees for attendance at meetings and
reimbursement of expenses, Messrs. Grundhofer and Seymour will each receive
$20,000 for their service as members of the special committee evaluating the
merger proposal by TIC Acquisition LLC through March 31, 1999 and Messrs. Frank
and McCoy will each receive $50,000 for their service as Co-Chairmen of the

CERTAIN RIGHTS OF THE IRVINE COMPANY WITH RESPECT TO THE BOARD OF DIRECTORS
 
     Pursuant to the Miscellaneous Rights Agreement, The Irvine Company, its
shareholders and affiliates and Mr. Bren and his affiliates (the "Irvine
Persons") have the right, and will continue to have the right so long as the
Irvine Persons beneficially own at least 20% of the outstanding Common Stock
(including for this purpose Common Stock issuable upon exchange of common
limited partner interests ("Common L.P. Units") in the Operating Partnership),
to nominate three persons (each, an "Irvine Company Board Representative") for
election to the Board of Directors of the Company. In the event this ownership
falls below 20% but is at least 15%, the Irvine Persons will have the right to
nominate two persons for election to the Board of Directors; and if this
ownership falls below 15% but is at least 10%, the Irvine Persons will have the
right to nominate one person for election to the Board of Directors. In
connection with the foregoing, the Irvine Company is authorized to act for the
Irvine Persons. The three current Directors nominated by the Irvine Persons are
Messrs. Bren, McKee and Watson.
 
     Two provisions of the Company's Articles of Incorporation give The Irvine
Company additional rights with respect to the Company's Board of Directors:
 
     First, the Company's Articles of Incorporation provide that a majority of
the entire Board of Directors of the Company including at least one Irvine
Company Board Representative shall constitute a quorum for Board of Directors
action at any meeting.
 
                                       37
<PAGE>   38
 
     Second, the Company's Articles of Incorporation provide that approval of
the Required Directors is required to approve (i) a change of control (as
defined therein) of the Company or the Operating Partnership; (ii) any amendment
to the Company's Articles of Incorporation or Company Bylaws or the partnership
agreement of the Operating Partnership (the "Partnership Agreement"); (iii) any
waiver or modification of the ownership limit provisions of the Company's
Articles of Incorporation; (iv) any merger, consolidation, statutory share
exchange or sale of all or substantially all of the assets of the Company or the
Operating Partnership; (v) subject to certain exceptions, the issuance of equity
securities of the Company; (vi) the Company taking title to assets or to conduct
business other than through the Operating Partnership, or for the Company or the
Operating Partnership to engage in another line of business; (vii) the Company
or the Operating Partnership making a general assignment for the benefit of
creditors or instituting (or consent to the institution of) proceedings in
bankruptcy or for the liquidation, dissolution, reorganization or winding-up of
the Company or the Operating Partnership; and (viii) termination of the
Company's status as a real estate investment trust for federal income tax
purposes.
 
EMPLOYMENT AND TERMINATION OF EMPLOYMENT AGREEMENTS
 
     William H. McFarland was appointed Chief Executive Officer and President of
the Company on July 15, 1997. Pursuant to an agreement entered into at the
commencement of his employment with the Company, Mr. McFarland received an
annualized base salary of $400,000 for 1997 and is eligible for an annual bonus
of 0% to 100% of his base salary, with $183,000 and $400,000 guaranteed for 1997
and 1998, respectively. In addition, the agreement provides that Mr. McFarland
will be a participant in the Company's fringe benefit programs and long-term
incentive plans. Upon hire Mr. McFarland received options to purchase 100,000
shares of Common Stock and also received (i) for 1997 a grant of 27,500
restricted stock units vesting 0% in 1997, 20% in each of 1998, 1999 and 2000
and 40% in 2001 and (ii) for 1998 a grant of 27,500 restricted stock units
vesting 0% in 1998, 20% in each of 1999 and 2000 and 60% in 2001, and will
receive an annual award of 27,500 restricted stock units in each of the years
1999 and 2000 assuming continued employment. These restricted stock unit awards
will vest automatically on December 31 of each year and do not require that any
performance targets be met; the restricted stock unit awards to be granted in
1999 and 2000 each vest over periods ending in 2001. In addition, upon Mr.
McFarland's death or disability or if Mr. McFarland is terminated without cause,
all unvested restricted stock unit awards will vest immediately and all then
ungranted restricted stock units will also be granted to Mr. McFarland and will
immediately vest. Pursuant to one of the letter agreements described below, in
the event of a business transaction such as the merger between the Company and a
subsidiary of The Irvine Company, Mr. McFarland will not receive any of the
options to which he would otherwise be entitled, but he will receive payments
with respect to future restricted stock units as set forth in the letter
agreements.
 
     Under an agreement between him and the Company (superseded by a later
agreement as described below) covering the period January 1, 1998 to December
31, 2002, James E. Mead, the former Senior Vice President, Chief Financial
Officer and Secretary of the Company, was entitled to an annualized base salary
of $250,000, subject to increase at the discretion of the Compensation
Committee, and an annual bonus of 0% to 100% of his base salary. In addition,
the agreement provided that Mr. Mead would be a participant in the Company's
fringe benefit programs and long-term incentive plans. In accordance with the
agreement, Mr. Mead was granted for 1998 options to purchase 38,000 shares of
Common Stock and a restricted stock unit award with respect to 20,000 shares of
Common Stock vesting 0% in 1998, 20% in each of 1999, 2000 and 2001 and 40% in
2002, and assuming continued employment, would have been awarded options to
purchase 25,000 shares and 20,000 shares in 1999 and 2000, respectively, and
10,000 restricted stock units in each of 1999 and 2000, such restricted stock
units to vest over periods ending in 2002. All such restricted stock units were
eligible for vesting in accordance with FAD per share targets established or, in
the case of the 1999 and 2000 awards, to be established by the Compensation
Committee. With respect to the 1999 and 2000 restricted stock unit awards,
shares not earned by 2002 would have remained eligible for vesting until 2003 in
the case of the 1999 award, and 2004 in the case of the 2000 award. If Mr.
Mead's employment had been terminated involuntarily, other than for cause, prior
to December 31, 2000 he would have received a severance payment of 24 months
salary; if such termination had been between January 1, 2001 and December 31,
2002, he would have received a severance payment of 18 months salary.
                                       38
<PAGE>   39
 
     In October 1998, the Company announced that Mr. Mead would be resigning in
early 1999 to pursue other opportunities. In connection with Mr. Mead's
resignation, the Company entered into an agreement with Mr. Mead revising the
terms of his employment. Pursuant to the agreement, Mr. Mead was entitled to the
payment on or about February 1, 1999 of a cash bonus of $165,000 and an
additional payment of $375,000. At such time, all vesting of Mr. Mead's
restricted stock units and options ceased. All of Mr. Mead's vested options will
remain exercisable for 90 days from the date of Mr. Mead's termination of
employment with the Company. The agreement also provides for Mr. Mead to remain
as a consultant to the Company for 6 months for a total of $125,000 and to
continue to participate in the Company's fringe benefit programs.
 
     Pursuant to an agreement between him and the Company, Richard E. Lamprecht
was promoted to the position of Senior Vice President, and President, Irvine
Ranch Division. The agreement provides for an annualized base salary of $200,000
and a cash bonus for 1997 of $200,000. The agreement provides that in future
years Mr. Lamprecht will be eligible for an annual bonus of 0% to 100% of his
base salary. Pursuant to the agreement, Mr. Lamprecht was granted in 1997
options to purchase 20,000 shares of Common Stock (which award was in addition
to options to purchase 10,000 shares of Common Stock previously granted in 1997)
and a restricted stock unit award in respect of 10,000 shares of Common Stock.
In addition, Mr. Lamprecht will receive in each of 1998 through 2001 options to
purchase 10,000 shares and a restricted stock unit award in respect of 4,000
shares of Common Stock, assuming continued employment. Pursuant to one of the
letter agreements described below, in the event of a business transaction such
as the merger between the Company and a subsidiary of The Irvine Company, Mr.
Lamprecht will not receive any of the options or restricted stock units to which
he would otherwise be entitled.
 
     The Company has entered into letter agreements dated January 22, 1999 with
each holder of employee options or restricted stock units. The letter agreements
will have no effect unless a business combination, such as the merger between
the Company and a subsidiary of The Irvine Company, is consummated. The letter
agreements provide that each holder of an employee option will be entitled to
receive a cash amount equal to the excess of $34.00 over the exercise price for
each share of the Company's common stock subject to the option, payable at the
consummation of the merger if then vested, or at the time such option or portion
of an option would otherwise have vested according to the relevant award
agreement. In the case of a restricted stock unit, the letter agreements provide
that each holder will be entitled to receive a cash amount equal to $34.00 per
restricted stock unit, payable at the time such restricted stock unit would
otherwise have been available for vesting according to the relevant award
agreement, assuming the achievement of all applicable performance targets for
the relevant periods. In the case of Mr. McFarland's future restricted stock
units, his letter agreement provides that he will be entitled to receive a cash
amount equal to $34.00 per future restricted stock unit, payable at the time the
future restricted stock units would otherwise have been available for vesting
according to Mr. McFarland's original agreement, assuming that restricted stock
units had been granted to Mr. McFarland in accordance with the terms of Mr.
McFarland's original agreement. It is a condition of payment with respect to
both options and restricted stock units that the holder remain continuously
employed by the Company until the respective payment dates. The restricted stock
unit amounts will bear interest from the consummation of the merger to the
relevant payment date, payable on the last day of each calendar quarter, at the
annual rate of 5% through February 29, 2000, and 6% from March 1, 2000 until the
date such restricted stock unit would have been available for vesting or, if
sooner, until payment for such restricted stock units is accelerated in
accordance with the letter agreements. Interest will be payable in cash as
promptly as practicable following each interest payment date.
 
     Pursuant to the letter agreements, in the event that a holder's employment
is terminated involuntarily by the Company without cause or by the holder for
good reason (as defined in the letter agreements) prior to the relevant payment
date, payment for unvested options and restricted stock units will be
accelerated and made within 10 days after such employment termination date.
 
     The table below shows the options and restricted stock units (and future
restricted stock units) currently held by each of the Named Executive Officers
and the amounts in respect of such options and restricted stock units (and
future restricted stock units) such individuals will be entitled to receive at
the consummation, if any, of the merger and in the future (not including
interest). All amounts to be paid at the consummation of the merger relate to
vested options.

     Messrs. McFarland, Thompson and Lamprecht (each, an "executive") also
entered into termination protection and severance arrangements with the Company
set forth in their letter agreements, which provide that, in addition to the
above-mentioned treatment of options and restricted stock units (and future
units), an executive whose employment is terminated involuntarily by the Company
without cause, or by himself for good reason within eighteen months following
the consummation of the merger, will be entitled to one year's base salary at
the rate in effect at either (i) the time of his termination of employment or
(ii) the consummation of the merger, whichever is higher. Such amount will be
paid to the executive in a lump sum, without reduction for the time value of
money, as soon as practicable, but in any event within 10 days, after the date
of his termination of employment. The severance benefits payable under the
letter agreements depend on the effective rate of the base salary applicable to
an executive at the time of his termination of employment. Therefore, the
severance amount payable to an executive is not precisely determinable. However,
assuming termination at current levels of base salaries, the amounts that would
be payable to Messrs. McFarland, Thompson and Lamprecht, if paid currently,
would be $400,000, $275,000 and $200,000, respectively.
 
SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Exchange Act requires the Company's executive officers
and directors, and beneficial owners of more than 10% of the Common Stock of the
Company, to file initial reports of ownership and reports of changes in
ownership with the Securities and Exchange Commission and the NYSE. Executive
officers and directors are required by Securities and Exchange Commission
regulations to furnish the Company with copies of all Section 16(a) forms they
file. Based solely on a review of the copies of such forms furnished to the
Company and written representations from the Company's executive officers and
directors, the Company noted that no individual who, at any time during 1998,
was a director, officer or beneficial owner of more than 10% of the Common Stock
of the Company failed to file the reports required by Section 16(a) of the 1934
Act on a timely basis, except that Form 4s were filed late with respect to the
vesting of restricted stock units in February 1998 for Messrs. Alfred Baker,
Howie, Lamprecht, McAllister, Mead and Reinert.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
TRANSACTIONS WITH THE IRVINE COMPANY
 
     The Company and The Irvine Company have entered into an administrative
services agreement, as amended, pursuant to which The Irvine Company provides
the Company with certain administrative services, including, but not limited to,
income tax services, risk management and other support services. During 1998,
the Company incurred costs of approximately $185,000 pursuant to the
administrative services agreement.
 
     The Company and The Irvine Company have also entered into leases pursuant
to which the Company leases space from The Irvine Company. Pursuant to the
leases, $447,000 was incurred in 1998. The Company also incurred parking costs
to The Irvine Company of approximately $52,000 in 1998.
 
     Two of the Company's apartment communities are financed by mortgage notes
payable to The Irvine Company. These mortgage notes totaled $49,517,000 at
December 31, 1998. The mortgage notes are collateralized by all-inclusive trust
deeds on each of the apartment communities financed, bore fixed interest rates
of 5.75% at December 31, 1998, are fully amortizing, and mature in 2015 and
2024. Interest incurred on the mortgage notes payable to The Irvine Company
totaled $2,871,000 for the year ended December 31, 1998. The mortgage notes
payable to The Irvine Company "wrap around" secured first trust deed notes
payable to third party financial institutions. The secured first trust deed
notes totaled $49,890,000 as of December 31, 1998. As of January 31, 1999, the
amount outstanding under each note was $16,228,000 and $33,214,000.
 
     In addition, during 1998, the Company sold in the aggregate 78,272 shares
of Common Stock to The Irvine Company at varying prices ranging from $25.449 to
$30.043 per share pursuant to its Dividend
                                       42
<PAGE>   43
 
Reinvestment and Additional Cash Investment Plan. In connection with such sales,
The Irvine Company, pursuant to its rights under the Partnership Agreement and
the Miscellaneous Rights Agreement, purchased an aggregate of 108,306 Common
L.P. Units and 25,812 shares of Common Stock at varying prices ranging from
$25.449 to $30.656. All of the foregoing Common L.P. Units are exchangeable for
Common Stock on a one for one basis, subject to adjustment and certain
limitations.
 
     The Company, the Operating Partnership, and The Irvine Company are parties
to the Land Rights Agreement. This Agreement, which extends through July 31,
2020, provides the Company the exclusive right, but not the obligation, to
acquire additional land sites on the Irvine Ranch which have been entitled for
residential use and designated by The Irvine Company as ready for apartment
development in accordance with the Master Plan. The determination to exercise an
option with respect to a site is made solely by a majority of the Independent
Directors Committee of the Company's Board of Directors. In addition, The Irvine
Company and Donald Bren have agreed to conduct their apartment community
development and ownership activities on the Irvine Ranch solely through the
Company.
 
     Pursuant to the Land Rights Agreement, The Irvine Company and Mr. Bren have
agreed not to directly or indirectly acquire or develop, or acquire an equity
interest in any entity that has an ownership interest in, any rental apartment
community whether on or off the Irvine Ranch. This prohibition terminates, with
respect to communities on the Irvine Ranch, on July 31, 2020, and with respect
to communities off the Irvine, when (i) no nominee of The Irvine Company is a
member of the Company's Board of Directors and (ii) The Irvine Company and
certain related persons beneficially own less than 20% of the outstanding Common
Stock in the aggregate (including for this purpose Common Stock issuable upon
exchange of Common L.P. Units).
 
     The Land Rights Agreement is subject to early termination upon the
occurrence of certain events including (i) the failure of the shareholders of
the Company to elect as directors of the Company the number of directors which
The Irvine Company is entitled to nominate to the Company's Board of Directors,
(ii) in the event of a vacancy on the Board of Directors of an Irvine Company
Board Representative, the remaining directors shall not promptly elect a person
designated by The Irvine Company to fill such vacancy or (iii) during the period
The Irvine Company has the right to nominate three persons to the Company's
Board of Directors, the provisions of the Articles of Incorporation and the
Bylaws requiring approval of the Required Directors to take certain actions
shall be repealed, modified or amended without the prior written consent of The
Irvine Company.
 
     Under the terms of the Land Rights Agreement, through July 31, 2000, the
purchase price for any apartment community sites acquired may be paid with
either cash, Common Stock or Common L.P. Units, at the option of the Company.
After July 31, 2000, the choice of consideration will revert to The Irvine
Company. In no event shall the purchase price for any apartment community land
site exceed 95% of the value of such site as determined by independent
appraisals. In addition, the purchase price for apartment sites encompassing the
first 1,800 apartment units the Company develops starting in mid-1995 was set at
an amount such that each project's budgeted pro forma unleveraged return on
costs for the first 12 months following stabilized occupancy was between 10.0%
and 10.5%. Seven land sites, which will contain a total of 1,884 apartment
units, were purchased under this arrangement. Accordingly, the purchase price
for all future land acquisitions under the Land Rights Agreement will be no
greater than 95% of the appraised value.
 
     Pursuant to the Land Rights Agreement, if the Company elects not to
exercise its option for any site, the Company will thereafter have a right of
first refusal on the sale of such site to a third party if the terms of such
sale are more favorable than those offered to the Company. The determination to
exercise an option or the right of first refusal under the Land Rights Agreement
with respect to any site will be made solely by a majority of the Independent
Directors Committee.
 
     Three Directors of the Company, Messrs. Bren, McKee and Watson, are
affiliated with The Irvine Company. Mr. Bren is Chairman of the Board and the
sole stockholder of The Irvine Company. Mr. McKee is Executive Vice President
and Chief Financial Officer and a director of The Irvine Company. Mr. Watson is
Vice Chairman of the Board of The Irvine Company.
 
                                       43
<PAGE>   44
 
     The respective interests of the Company and The Irvine Company (and certain
of its affiliates) in the Operating Partnership were 44.6% and 55.2%,
respectively, at December 31, 1998, and 44.4% and 55.4%, respectively, at
December 31, 1997.
 
     Going Private Transaction
 
     On February 1, 1999, the Company and TIC Acquisition LLC, an indirect
wholly owned subsidiary of The Irvine Company, entered into a definitive merger
agreement providing for a merger of the Company into TIC Acquisition LLC in
which the Company's shareholders will receive $34 in cash per share. The
transaction, which is subject to the approval of the holders of (i) at least
two-thirds of the outstanding shares of common stock of the Company and (ii) a
number of shares of common stock of the Company (excluding the shares held by
TIC Acquisition LLC and its affiliates) representing a majority of the total
number of shares of common stock of the Company entitled to vote, and other
customary conditions, is expected to be completed late in the second quarter or
early in the third quarter of 1999.
 
AGREEMENT RELATING TO THOMPSON RESIDENTIAL COMPANY, INC.
 
     On February 4, 1997, the Operating Partnership acquired the assets
(primarily options on three parcels of land in Northern California) of Thompson
Residential Company, Inc. ("TRC") in exchange for 74,523 Common L.P. Units in
the Operating Partnership (currently approximately 0.2% of the Common L.P. Units
outstanding). In addition, TRC is entitled to an "earn out" based on the
performance of the apartment community built on one of the three parcels of
land, up to a maximum of $2,000,000. Concurrently with these transactions, each
of the three owners of TRC (William W. Thompson, Bruce N. Dorfman and Robert J.
Hughes) became officers of the Company.
 
     The Operating Partnership has entered into a Stock Purchase Agreement with
Messrs. Thompson, Dorfman and Hughes, pursuant to which they will sell their
shares in TRC to the Operating Partnership or its assignee for an aggregate of
$4,533,782. The consummation of the Stock Purchase Agreement is conditioned upon
the merger of the Company with TIC Acquisition LLC.
 
OTHER TRANSACTIONS
 
     Mr. Grundhofer is Chairman, President and Chief Executive Officer of U.S.
Bancorp (formerly First Bank System, Inc.) which, through an affiliate, is a
member of the bank syndicate that provided the Company's $250,000,000 revolving
credit facility. There was no outstanding balance under the credit facility as
of February 16, 1999. An affiliate of U.S. Bancorp is also a member of the bank
syndicate that provided the Company's $100,000,000 term loan facility. Based on
this bank's percentage participation in these credit facilities (and the
predecessor facilities), the Company estimates that the amount of interest and
fees paid to the affiliate totaled $364,000 in 1998.

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
NOTE 1 -- ORGANIZATION AND BASIS OF PRESENTATION
 
     Irvine Apartment Communities, Inc., a Maryland corporation (the "Company"),
operates as a real estate investment trust ("REIT") under the Internal Revenue
Code of 1986, as amended. In connection with the Company's initial public
offering of common stock (the "Offering"), the Company obtained a general
partnership interest in and became the sole managing general partner of Irvine
Apartment Communities, L.P., a Delaware limited partnership (the "Operating
Partnership"). The Operating Partnership was formed on November 15, 1993 and
began operations as of December 8, 1993, the date of the Offering. In connection
with the Offering, The Irvine Company transferred 42 apartment communities and a
99% interest in a limited partnership which owns one apartment community to the
Operating Partnership. At December 31, 1998, the Company had a 44.6% general
partnership interest in and was the sole managing general partner of the
Operating Partnership. At December 31, 1998, the common limited partners had a
55.4% common limited partnership interest in the Operating Partnership, with The
Irvine Company and certain of its affiliates owning a 55.2% common limited
partnership interest in the Operating Partnership. In addition, at December 31,
1998, The Irvine Company and certain of its affiliates owned approximately 17.9%
of the common shares of the Company. In February 1997, the Operating Partnership
acquired the assets of Thompson Residential Company, Inc. The purchase price was
paid by the issuance of 74,523 common limited partnership units in the Operating
Partnership. At December 31, 1998, Thompson Residential Company, Inc. had a 0.2%
common limited partnership interest in the Operating Partnership. The Operating
Partnership's management and operating decisions are under the unilateral
control of the Company. The Company was incorporated in Delaware on September
10, 1993. In May 1996, the Company changed its state of incorporation from
Delaware to Maryland.
 
     The Company is a self-administered equity REIT engaged in the operation and
development (through the Operating Partnership) of apartment communities in
Orange County, California and, beginning in 1997, other locations in California.
As of December 31, 1998, the Operating Partnership owned 65 apartment
communities representing 16,439 operating apartment units and 3,039 apartment
units under construction or development (collectively, the "Properties"). In
March 1998, the Operating Partnership and Western National Property Management
("WNPM") announced the formation of a strategic alliance that, in April 1998,
assumed all property management responsibilities for the Operating Partnership's
Southern California portfolio. The new entity, Irvine Apartment Management
Company ("IAMC"), is owned 51% by the Operating Partnership and 49% by WNPM.
Until July 31, 2020, the Company and the Operating Partnership have the
exclusive right, but not the obligation, to acquire land from The Irvine Company
for development of additional apartment communities on the Irvine Ranch.
 
     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 Company and the Operating Partnership. The Trust exists for the sole
purpose of issuing redeemable preferred securities and investing the proceeds
thereof in preferred limited partner units of the Operating Partnership.
 
     The accompanying financial statements of the Company include the
consolidated accounts of the Operating Partnership and its financially
controlled subsidiaries. All intercompany accounts and transactions have been
eliminated in consolidation.
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities as of
December 31, 1998 and 1997, and the revenues and expenses for the three years
ended December 31, 1998. Actual results could differ from those estimates.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     REAL ESTATE ASSETS AND DEPRECIATION: Real estate assets, which are held as
long-term investments, are stated at cost less accumulated depreciation.
Impairment losses on long-lived assets used in operations are recorded when
events and circumstances indicate that the assets, on a property-by-property
basis, are impaired and the undiscounted cash flows estimated to be generated by
those assets are less than the carrying amounts. As of December 31, 1998, no
impairment losses have been recorded. Land and infrastructure costs are
allocated to properties based on relative fair value. Costs related to the
development and construction of properties are capitalized as incurred. Interest
and property taxes are capitalized to apartment communities which are under
active development. When a building within a community under construction is
completed and held available for occupancy, the related costs are expensed.
 
     Repair and maintenance expenditures are expensed as incurred. Major
replacements and betterments are capitalized and depreciated over their useful
lives. Depreciation is computed on a straight-line basis over the useful lives
of the properties (principally forty years for buildings; twenty years for
siding, roofs and balconies; fifteen years for plumbing and air conditioning
equipment; ten years for pools, tennis courts, parking lots and driveways; and
five to ten years for furniture and fixtures).
 
     CASH AND CASH EQUIVALENTS: The Company considers all highly liquid
investments with a remaining original maturity when purchased of three months or
less to be cash equivalents.
 
     RESTRICTED CASH: Restricted cash is comprised of reserve accounts for
capital replacements, property taxes and insurance. These restricted funds are
subject to supervision and approval by a lender or a government agency. The
terms of the contract with the government agency contain certain restrictions
concerning operating policies, rental charges, operating expenditures,
distributions to owners and other matters.
 
     DEFERRED FINANCING COSTS: Costs incurred in obtaining long-term financing
or costs to buy down or hedge interest costs are deferred and amortized over the
term of the related debt agreements using the effective interest method.
 
     REVENUE RECOGNITION: The Company leases apartment units to a diverse
resident base for terms of one year or less. Credit investigations are performed
for all prospective residents and security deposits are also obtained. Resident
receivables are evaluated for collectibility each month. Rental revenue is
recognized on an accrual basis as it is earned over the life of the lease.
Interest income is recorded as earned.
 
     INTEREST EXPENSE: Interest rates are substantially fixed for specified
periods through interest rate swaps and buy-down agreements for certain debt
instruments. These financial instruments are entered into as a hedge against the
interest exposure from variable rate debt. The differences paid or received on
swaps and related agreements are included in interest expense as yield
adjustments.
 
     INCOME TAXES: The Company has elected to be taxed as a REIT and, as such,
will generally not be subject to federal and state income taxation at the
corporate level. To maintain its REIT status, the Company is required to
distribute annually at least 95% of its REIT taxable income to its shareholders
and to satisfy certain other requirements. Accordingly, no provision has been
made for federal income taxes in the accompanying statements of operations.
 
     PER SHARE DATA: All earnings per share amounts for all periods reflect
basic and diluted earnings per share and have been restated from the previous
standard of primary and fully diluted earnings per share. See Note 10 for
additional information regarding basic and diluted earnings per share.
 
     DESCRIPTIVE INFORMATION ABOUT REPORTABLE SEGMENTS: During the fourth
quarter of 1998, the Company adopted the Financial Accounting Standards Board's
Statement of Financial Accounting Standards No. 131,

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
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 Company.
 
     The Company operates and develops apartment communities in California which
generated rental and other income through the leasing of apartment units to a
diverse base of renters. The Company separately evaluates the performance of
each of its apartment communities. However, because each of the apartment
communities have similar economic characteristics, facilities, services and
tenants, the apartment communities have been aggregated into a single dominant
apartment communities segment.
 
     The Company evaluates performance and allocates resources primarily based
on the net operating income ("NOI") of individual apartment communities. NOI is
defined by the Company 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 $152,766,
$126,536 and $106,230 for the years ended December 31, 1998, 1997 and 1996,
respectively. All other segment measurements are disclosed in the Company's
consolidated financial statements.
 
     All revenues are from external customers and no revenues are generated from
transactions with other segments. There are no tenants which contributed 10% or
more of the Company's total revenues during 1998, 1997 or 1996. Interest expense
on debt is not allocated to individual apartment communities, even if such debt
is secured by the apartment communities. Further, minority interest in
consolidated subsidiaries is not allocated to the apartment communities. There
is no provision for income taxes as the Company is organized as a REIT under the
Internal Revenue Code.
 
     RECLASSIFICATIONS: Certain amounts in the 1997 and 1996 financial
statements have been reclassified to conform with financial statement
presentations in 1998.
 
NOTE 3 -- MORTGAGES AND NOTES PAYABLE
 
     TAX-EXEMPT MORTGAGE BOND FINANCINGS: In October 1998, the Operating
Partnership assumed $18 million in tax-exempt mortgage bond financings
associated with the purchase of a 216-unit apartment community ("One Park
Place"). The tax-exempt financings represent loans payable that are
collateralized by One Park Place. Monthly 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 April 2025.
 
     CONVENTIONAL MORTGAGE FINANCINGS: Conventional mortgages are collateralized
by apartment communities having a net book value of $145,120 as of December 31,
1998. The mortgages are generally due in monthly installments and mature at
various dates through 2018. Prior to the Offering, interest rates were fixed at
rates which ranged from 7.75% to 9.63%, with a weighted average rate of 8.69%.
In connection with the Offering, the interest rates were adjusted to market
rates for specified periods of time and currently range from 6.31% to 8.30%. As
of December 31, 1998, the weighted average interest rate was 7.12%. Including
the amortization of deferred financing costs, the all-in interest rate was
8.30%. The interest reduction periods expire prior to or at the loan maturity
dates and range from 2000 to 2008.

all-inclusive trust deeds on each of the apartment communities financed. They
bore fixed interest rates of 5.75% at December 31, 1998, are fully amortizing
and mature in 2015 and 2024. Interest incurred on the mortgage notes payable to

December 31, 1998, 1997 and 1996, respectively. The mortgage notes payable to
The Irvine Company "wrap around" secured first trust deed notes payable to
third-party financial institutions. The secured first trust deed notes totaled
$49,890 and $50,651 as of December 31, 1998 and 1997, respectively.
 
     TAX-EXEMPT ASSESSMENT DISTRICT DEBT: In connection with the Offering, the
Operating Partnership assumed certain tax-exempt assessment district debt of the
predecessor entity. In conjunction with the purchase of land, the Operating
Partnership assumed $2,771 in 1996 in tax-exempt assessment district debt.
Tax-exempt assessment district debt represents debt issued by municipal
government authorities to finance the construction of infrastructure and
improvements. The debt obligations are repaid by the Operating Partnership
through assessments.
 
     UNSECURED TAX-EXEMPT BOND FINANCINGS: In June 1998, the Operating
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 Operating Partnership's
existing tax-exempt mortgage debt and to pay costs associated with prepayment
penalties and the unwinding of certain swap agreements. The Operating
Partnership recorded an extraordinary item related to debt extinguishment of
$42.5 million in June 1998.
 
     UNSECURED TERM LOAN: In November 1998, the Operating Partnership placed a
$100 million unsecured term loan with two banks. The term loan is interest-only
and bears interest at LIBOR plus 1.5%. The floating rate has been fixed through
an interest rate swap agreement. The term loan is due in November 1999. The term
loan can be extended for two six-month periods if the loan is not in default.
 
     UNSECURED NOTES PAYABLE: In October 1997, the Operating Partnership issued
$100 million aggregate principal amount of 7% senior unsecured notes term
pursuant to its shelf registration statement. The notes are due on October 1,
2007. Net proceeds from the offering of $97.9 million were used to repay
indebtedness under the Operating Partnership's line of credit. The Operating
Partnership was in compliance with all covenant requirements at December 31,
1998.
 
     UNSECURED LINE OF CREDIT: The Operating Partnership has a $250 million
unsecured revolving credit facility that was amended in July 1998. The amended
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 Operating Partnership's senior
unsecured long-term indebtedness. Under the credit facility, the Operating
Partnership is able to borrow funds from the participating banks through a
competitive bid process to obtain a lower interest rate. The Operating
Partnership may also enter into letters of credit under the facility. Borrowings
under the credit facility, which are guaranteed by the Company, are available to
finance the Operating Partnership's ongoing rental property development,
possible acquisitions and for general working capital needs. The Company and the
Operating Partnership must comply with certain affirmative and negative
covenants, including limitations on distributions, and the maintenance of
certain net worth, cash flow and financial ratios. At December 31, 1998, the
Company and the Operating Partnership were in compliance with all of these
covenants. In 1998, the Company entered into letters of credit under the
facility totaling $29.1 million related to acquisitions. The letters of credit
reduce the remaining amount available under the line of credit. As of December
31, 1998, there was no outstanding balance under the line of credit and $220.9
million was available.
 
     INTEREST RATE SWAP AGREEMENT: The Operating Partnership uses an interest
rate swap agreement to effectively convert its floating rate unsecured term loan
to a fixed-rate basis, thus reducing the impact on future income of fluctuations
in interest rates. The swap agreement terminates in 1999. The swap counterparty
is a financial institution rated AAA by Standard & Poor's. The difference to be
paid or received is accrued and included in interest expense as a yield
adjustment and the related amount payable or receivable from the counterparty is
included in accrued liabilities or other assets. Additionally, the Operating
Partnership

restructured several interest rate swaps related to the retired tax-exempt bonds
in May 1995. One of the transactions reduces the interest expense on unsecured
tax-exempt bond financings by approximately 30 basis points per year through
2001. At December 31, 1998, the average fixed interest rate paid to the
counterparty was 4.88% and the average variable interest rate received was
5.56%. This resulted in a net interest receivable of $56 which was settled on
January 20, 1999. Based on prevailing interest rates at December 31, 1998, the
interest rate swap agreement had a fair value of $2,762.
 
     TREASURY RATE LOCK AGREEMENTS: The Operating Partnership entered into
treasury rate lock agreements to hedge a planned debt offering of $100 million
and lock into a treasury rate of 5.67%. In November 1998, the Operating
Partnership terminated all of its outstanding treasury rate lock agreements
because management determined that the planned debt offering would not occur.
The cost of terminating these agreements was $7.8 million.
 
     CAPITALIZED INTEREST: The Company capitalizes interest on projects actively
under development using qualifying asset balances and applicable weighted
average interest rates. The average qualifying asset balance for projects under
development was approximately $156.4 million, $76.6 million and $40.0 million
for the years ended December 31, 1998, 1997 and 1996, respectively. Interest
capitalized was $12,280, $5,704 and $3,151 in 1998, 1997 and 1996, respectively.
Interest incurred totaled $40,102, $36,072 and $32,657 for the years ended
December 31, 1998, 1997 and 1996, respectively.
 
     OTHER MATTERS: Mortgages and notes payable totaling $198,190 are subject to
prepayment penalties.

NOTE 4 -- FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts reported in the balance sheet for financial
instruments approximate their fair value except as discussed below. The fair
values of the conventional mortgage financings and the mortgage notes payable to
The Irvine Company are estimated using discounted cash flow analyses and the
Company's current estimated borrowing rates for similar types of borrowing
arrangements. The interest rate used in the fair value calculation ranges from
6.3% to 7.3% based on the terms of the loan. As of December 31, 1998, the fair
values of the conventional mortgage financings and the mortgage notes payable to
The Irvine Company were $135,938 and $43,432, respectively. The fair values of
the unsecured notes payable and unsecured tax-exempt bond financings based on
the prevailing interest rates at December 31, 1998 were $89,096 and $339,886,
respectively.
 
NOTE 5 -- MINORITY REDEEMABLE PREFERRED INTERESTS
 
     In January 1998, IAC Capital 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
Operating Partnership. The Operating Partnership used the $150 million of
proceeds, net of costs and offering expenses, all of which were paid by the
Operating Partnership, to repay the outstanding balance on the Operating
Partnership's credit facility and to fund development.

     In November 1998, the Operating Partnership issued 2.0 million of 8 3/4%
Series B Preferred Limited Partner Units. The Operating Partnership used the net
proceeds to reduce the outstanding balance on its unsecured line of credit.
 
NOTE 6 -- EQUITY
 
     In July 1996, the Company completed the sale of 1.49 million shares of
common stock at $20.125 per share. The proceeds from this offering of $30.0
million, together with proceeds from the sale of newly issued common limited
partnership units to The Irvine Company, totaled $60.0 million. Proceeds were
used to repay $43 million of debt outstanding under the revolving credit
facility. The remaining proceeds were used to fund ongoing development programs
and for general corporate purposes.
 
     In February 1997, the Company sold 1.15 million shares of common stock at
$27.50 per share. Concurrently, The Irvine Company, pursuant to its rights under
the Operating Partnership Agreement, purchased 1.39 million additional common
limited partnership units at $26.06 per unit (which is equal to the public
offering price of the common stock less an amount equivalent to the underwriting
discount) which are exchangeable for common stock on a one-for-one basis,
subject to adjustment and certain limitations. The proceeds from the two
transactions totaled $66 million and were used to repay all indebtedness
outstanding under the credit facility and for general corporate purposes,
including ongoing development activities on and off the Irvine Ranch.
 
     In May 1997, the Company filed a shelf registration statement with the
Securities and Exchange Commission providing for the issuance from time to time
of up to $350 million of common stock, preferred stock, and warrants to purchase
common stock and preferred stock. The Company plans to use the proceeds raised
from any securities issued under its shelf registration statement for general
corporate purposes, including the development of new apartment communities,
acquisitions and the repayment of existing debt. Availability under the
Company's shelf registration statement was $350 million at December 31, 1998.
Concurrently, the Operating Partnership filed a shelf registration statement
with the Securities and Exchange Commission providing for the issuance from time
to time of up to $350 million of debt securities. The Operating Partnership
plans to use the proceeds raised from any securities issued under its shelf
registration statement for general corporate purposes, including the development
of new apartment communities, acquisitions and the repayment of existing debt.
On October 1, 1997, the Operating Partnership issued $100 million aggregate
principal amount of 7% senior unsecured notes pursuant to its shelf registration
statement. Availability under the Operating Partnership's shelf registration
statement was $250 million at December 31, 1998.
 
     The Operating Partnership, pursuant to a Prospectus Supplement dated April
9, 1998, may issue from time to time up to $250 million aggregate initial
offering price of its Medium-Term Notes, Series A due nine months or more from
the date of issue. Issuances of Medium-Term Notes will reduce availability under
the Operating Partnership's Registration Statement by the amount of Medium-Term
Notes issued. Similarly, issuances of other debt securities under the Operating
Partnership's Registration Statement will reduce the amount of Medium-Term Notes
that may be used. As of December 31, 1998, there have been no issuances of
Medium-Term Notes.

NOTE 8 -- LAND RIGHTS AGREEMENT WITH THE IRVINE COMPANY
 
     The Company and The Irvine Company are parties to an exclusive land rights
and non-competition agreement (the "Land Rights Agreement"). This agreement,
which extends through July 31, 2020, provides the Company the exclusive right,
but not the obligation, to acquire additional land sites which have been
entitled for residential use and designated by The Irvine Company as ready for
apartment development in accordance with the Master Plan. The determination to
exercise an option with respect to a site is made solely by a majority of a
committee of independent directors of the Company, whose members are
unaffiliated with The Irvine Company. In addition, The Irvine Company and its
chairman, Donald Bren, have agreed to conduct their apartment community
development and ownership activities on the Irvine Ranch solely through the
Company.
 
     Under terms of the Land Rights Agreement, through July 31, 2000, the
purchase price for any apartment community sites acquired may be paid with
either cash, common stock or common limited partnership units at the option of
the Company. After July 31, 2000, the choice of consideration will revert to The
Irvine Company.

     Options to purchase 333,000 and 51,000 shares of common stock were
outstanding during 1998 and 1997, respectively, but were not included in the
computation of diluted earnings per share because the options' exercise price
was greater than the average market price of the common shares and, therefore,
the effect would be antidilutive. Convertible common limited partnership units
totaling 24,981,000, 23,930,000 and 21,221,000 were outstanding during 1998,
1997 and 1996, respectively, but were not included in the computation of diluted

     DIRECTORS' STOCK OPTION PLAN: The 1993 Stock Option Plan for Directors was
amended in 1998. The amended plan allows for 250,000 shares that may be granted
to independent directors and increases the annual number of options that may be
granted to 2,500. Grants of fully vested options to purchase 5,000 shares of
common stock at the market price on the grant date were made to each independent
director immediately following the Offering. Additionally, grants of fully
vested options to purchase 1,000 shares of common stock at the market price on
the grant date were made to each independent director immediately following each
annual shareholders' meeting from 1995 to 1997. In 1998, this amount was
increased to 2,500. These options are fully vested when granted and are
exercisable for ten years from the grant dates.

applied FAS Statement No. 123 for stock-based compensation, it would have
resulted in net income and earnings per share amounts that approximate the
amounts reported. Under FAS Statement No. 123, the fair value for options was
estimated at the date of grant using a Black-Scholes option pricing model with
the following weighted average assumptions for 1998, 1997 and 1996,
respectively: risk-free interest rates of 5.69%, 6.43%, and 6.46%; dividend
yields of 4.82%, 5.27% and 7.09%; volatility factors of the expected market
price of the Company's common stock of 0.191, 0.184 and 0.204; and a weighted
average expected life of the options of seven years.
 
NOTE 12 -- SAVINGS PLAN
 
     Effective January 1, 1994, the Company implemented a defined contribution
401(k) benefit plan covering substantially all employees who have satisfied
minimum age and service requirements. The Company matches employee contributions
up to 50%, within certain limits, which are accrued as incurred. The Company
also makes contributions to this plan for each participant generally equal to 3%
of the participant's base salary. The aggregate cost of these contributions by
the Company was $178, $125 and $122 in 1998, 1997 and 1996, respectively.
 
NOTE 13 -- AGREEMENTS, COMMITMENTS AND CONTINGENCIES
 
     MANAGEMENT AGREEMENT: The Company has a management agreement with IAMC
whereby IAMC has the exclusive right to manage all of the Company's properties
located on the Irvine Ranch and, to the extent practical, any other properties.
Management fees range from $15/unit/month to $28/unit/month depending on whether
the property is in lease-up or stabilized. The agreement expires in March 2001.
 
     LITIGATION: The Company is party to various legal actions which are
incidental to its business. Management believes that these actions will not have
a material adverse effect on the Company's consolidated financial statements.
 
     ASSESSMENT DISTRICTS: In some of the local jurisdictions within Orange
County where the predecessor entity developed property, assessment districts
were formed by local governments to finance major infrastructure improvements.
At December 31, 1998, the Company had $37.9 million of assessment district debt,
of which $21.3 million was reflected in the balance sheet.
 
     EXCHANGE RIGHTS: The Irvine Company and certain of its affiliates have the
right to exchange up to one-third of the total common limited partnership units
owned by them for shares of common stock in each twelve-month period commencing
on December 8 of each year at an exchange ratio of one-to-one, subject to
adjustment in certain events. These exchanges are subject to certain
restrictions including percentage ownership limits.
 
     COMPANY'S OBLIGATION TO PURCHASE TENDERED OPERATING PARTNERSHIP UNITS: The
Irvine Company and certain of its affiliates have the right to sell to the
Company for cash generally up to one-third of its common limited partnership
units in each twelve-month period commencing on December 8 of each year. These
sales are subject to certain restrictions. The Company is to purchase the
tendered interests at a purchase price equal to the average of the daily market
prices for the common stock of the Company for the ten consecutive trading days
immediately preceding the date of receipt by the Company of a notice of cash
tender. The Company is to pay for these interests solely with the net proceeds
of an offering of the Company's common stock. The Company and certain of its
affiliates would bear the costs of sale (other than underwriting discounts and
commissions). The Irvine Company and certain of its affiliates would bear all
market risk if the market price at closing was less than the purchase price as
determined on the date of tender. Any proceeds of the offering in excess of the
purchase price would be for the sole benefit of the Company.

     RENT RESTRICTIONS: As of December 31, 1998, 18.1% of the apartment units
within the Company's portfolio were required to be set aside for residents
within certain income levels and had limitations on the rent that could be
charged to such tenants. The rental revenue from five of these projects includes
governmental rent subsidy payments of $3,921, $3,903 and $3,977 for the years
ended December 31, 1998, 1997 and 1996, respectively.
 
NOTE 14 -- ACQUISITION OFFER FROM THE IRVINE COMPANY
 
     On February 1, 1999, the Company and TIC Acquisition LLC, a wholly-owned
subsidiary of The Irvine Company, entered into a definitive merger agreement
providing for the acquisition by TIC Acquisition LLC of all the outstanding
common shares of the Company in a business combination for $34 per share in
cash. Because the terms of the transaction are subject to various approvals,
there can be no assurance that the transaction will be consummated.

                         REPORT OF INDEPENDENT AUDITORS
 
To The Board of Directors and Shareholders
Irvine Apartment Communities, Inc.
 
     We have audited the accompanying consolidated balance sheets of Irvine
Apartment Communities, Inc. (the "Company") as of December 31, 1998 and 1997,
and the related consolidated statements of operations, changes in shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1998. Our audits also included the financial statement schedule on pages
F-21 to F-23. These financial statements and schedule are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements and schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of the Company at
December 31, 1998 and 1997, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31,
1998, in conformity with generally accepted accounting principles. Also, in our
opinion, the financial statement schedule referred to above, when considered in
relation to the basic financial statements taken as whole, presents fairly in
all material respects the information set forth therein.
 
                                                               ERNST & YOUNG LLP

NOTE 1 -- ORGANIZATION AND BASIS OF PRESENTATION
 
     Irvine Apartment Communities, L.P., a Delaware limited partnership (the
"Operating Partnership"), was formed on November 15, 1993. In connection with an
initial public offering (the "Offering") of common shares on December 8, 1993,
Irvine Apartment Communities, Inc. (the "Company") obtained a general
partnership interest in and became the sole managing general partner of the
Operating Partnership. The Irvine Company transferred 42 apartment communities
and a 99% interest in a limited partnership which owns one apartment community
to the Operating Partnership. The Operating Partnership's management and
operating decisions are under the unilateral control of the Company. All
management powers over the business and affairs of the Operating Partnership are
vested exclusively in the Company. No limited partner of the Operating
Partnership has any right to exercise control or management power over the
business and affairs of the Operating Partnership. At December 31, 1998, the
Company had a 44.6% general partnership interest in the Operating Partnership
and the limited partners had a 55.4% common limited partnership interest in the
Operating Partnership, with The Irvine Company and certain of its affiliates
owning a 55.2% common limited partnership interest. In addition, at December 31,
1998, The Irvine Company and certain of its affiliates owned approximately 17.9%
of the Company. In February 1997, the Operating Partnership acquired the assets
of Thompson Residential Company, Inc. The purchase price was paid by the
issuance of 74,523 common limited partnership units in the Operating
Partnership. At December 31, 1998, Thompson Residential Company, Inc. had a 0.2%
common limited partnership interest in the Operating Partnership.
 
     The Operating Partnership is engaged in the operation and development of
apartment communities in Orange County, California and, beginning in 1997, other
locations in California. As of December 31, 1998, the Operating Partnership
owned 65 apartment communities representing 16,439 operating apartment units and
3,039 apartment units under construction or development (collectively, the
"Properties"). In March 1998, the Operating Partnership and Western National
Property Management ("WNPM") announced the formation of a strategic alliance
that, in April 1998, assumed all property management responsibilities for the
Operating Partnership's Southern California portfolio. The new entity, Irvine
Apartment Management Company ("IAMC"), is owned 51% by the Operating Partnership
and 49% by WNPM. Until July 31, 2020, the Operating Partnership has the
exclusive right, but not the obligation, to acquire land from The Irvine Company
for development of additional apartment communities on the Irvine Ranch.
 
     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 Company and the Operating Partnership. The Trust exists for the sole
purpose of issuing redeemable preferred securities and investing the proceeds
thereof in preferred limited partner units of the Operating Partnership.
 
     Profits and losses are generally allocated to the Company and to the
limited partners based upon their respective ownership interests in the
Operating Partnership.
 
     The accompanying financial statements include the consolidated accounts of
the Operating Partnership and its financially controlled subsidiaries. All
intercompany accounts and transactions have been eliminated in consolidation.
 
     Under the terms of the partnership agreement, all costs incurred by the
Company relating to the ownership of interests in and operation of the Operating
Partnership, including the compensation of its officers and employees, stock
incentive plans, director fees and the costs and expenses of being a public
company, are reimbursed by the Operating Partnership. In addition, The Irvine
Company has the right, but not the obligation, to match on the same terms and
conditions any capital contributions made by the Company based on the pro rata
ownership interest at the time of such contribution.
 
     The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and

liabilities as of December 31, 1998 and 1997, and the revenues and expenses for
the three years ended December 31, 1998. Actual results could differ from those
estimates.
 
NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     REAL ESTATE ASSETS AND DEPRECIATION: Real estate assets, which are held as
long-term investments, are stated at cost less accumulated depreciation.
Impairment losses on long-lived assets used in operations are recorded when
events and circumstances indicate that the assets, on a property-by-property
basis, are impaired and the undiscounted cash flows estimated to be generated by
those assets are less than the carrying amounts. As of December 31, 1998, no
impairment losses have been recorded. Land and infrastructure costs are
allocated to properties based on relative fair value. Costs related to the
development and construction of properties are capitalized as incurred. Interest
and property taxes are capitalized to apartment communities which are under
active development. When a building within a community under construction is
completed and held available for occupancy, the related costs are expensed.
 
     Repair and maintenance expenditures are expensed as incurred. Major
replacements and betterments are capitalized and depreciated over their useful
lives. Depreciation is computed on a straight-line basis over the useful lives
of the properties (principally forty years for buildings; twenty years for
siding, roofs and balconies; fifteen years for plumbing and air conditioning
equipment; ten years for pools, tennis courts, parking lots and driveways; and
five to ten years for furniture and fixtures).
 
     CASH AND CASH EQUIVALENTS: The Operating Partnership considers all highly
liquid investments with a remaining original maturity when purchased of three
months or less to be cash equivalents.
 
     RESTRICTED CASH: Restricted cash is comprised of reserve accounts for
capital replacements, property taxes and insurance. These restricted funds are
subject to supervision and approval by a lender or a government agency. The
terms of the contract with the government agency contain certain restrictions
concerning operating policies, rental charges, operating expenditures,
distributions to owners and other matters.
 
     DEFERRED FINANCING COSTS: Costs incurred in obtaining long-term financing
or costs to buy down or hedge interest costs are deferred and amortized over the
term of the related debt agreements using the effective interest method.
 
     REVENUE RECOGNITION: The Operating Partnership leases apartment units to a
diverse resident base for terms of one year or less. Credit investigations are
performed for all prospective residents and security deposits are also obtained.
Resident receivables are evaluated for collectibility each month. Rental revenue
is recognized on an accrual basis as it is earned over the life of the lease.
Interest income is recorded as earned.
 
     INTEREST EXPENSE: Interest rates are substantially fixed for specified
periods through interest rate swaps and buy-down agreements for certain debt
instruments. These financial instruments are entered into as a hedge against the
interest exposure from variable rate debt. The differences paid or received on
swaps and related agreements are included in interest expense as yield
adjustments.
 
     INCOME TAXES: The Operating Partnership's taxable income is reportable by
its partners. Accordingly, no provision has been made for federal income taxes
in the accompanying statements of operations.
 
     PER UNIT DATA: All earnings per unit amounts for all periods reflect basic
and diluted earnings per unit and have been restated from the previous standard
of primary and fully diluted earnings per unit. See Note 10 for additional
information regarding basic and diluted earnings per unit.
 
     DESCRIPTIVE INFORMATION ABOUT REPORTABLE SEGMENTS: During the fourth
quarter of 1998, the Operating Partnership adopted the Financial Accounting
Standards Board's Statement of Financial Accounting

                (DOLLARS IN THOUSANDS, EXCEPT PER UNIT AMOUNTS)
 
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
Operating Partnership.
 
     The Operating Partnership operates and develops apartment communities in
California which generated rental and other income are through the leasing of
apartment units to a diverse base of renters. The Operating Partnership
separately evaluates the performance of each of its apartment communities.
However, because each of the apartment communities have similar economic
characteristics, facilities, services and tenants, the apartment communities
have been aggregated into a single dominant apartment communities segment.
 
     The Operating Partnership evaluates performance and allocates resources
primarily based on the net operating income ("NOI") of individual apartment
communities. NOI is defined by the Operating 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 $152,766, $126,536 and $106,230 for the years ended December
31, 1998, 1997 and 1996, respectively. All other segment measurements are
disclosed in the Operating Partnership's consolidated financial statements.
 
     All revenues are from external customers and there are no revenues from
transactions with other segments. There are no tenants which contributed 10% or
more of the total revenues during 1998, 1997 or 1996. Interest expense on debt
is not allocated to individual apartment communities, even if such debt is
secured by the apartment communities. There is no provision for income taxes as
the Operating Partnership's taxable income is reported by each of its partners.
 
     RECLASSIFICATIONS: Certain amounts in the 1997 and 1996 financial
statements have been reclassified to conform with financial statement
presentations in 1998.
 
NOTE 3 -- MORTGAGES AND NOTES PAYABLE
 
     TAX-EXEMPT MORTGAGE BOND FINANCINGS: In October 1998, the Operating
Partnership assumed $18 million in tax-exempt mortgage bond financings
associated with the purchase of a 216-unit apartment community ("One Park
Place"). The tax-exempt financings represent loans payable that are
collateralized by One Park Place. Monthly 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 April 2025.
 
     CONVENTIONAL MORTGAGE FINANCINGS: Conventional mortgages are collateralized
by apartment communities having a net book value of $145,120 as of December 31,
1998. The mortgages are generally due in monthly installments and mature at
various dates through 2018. Prior to the Offering, interest rates were fixed at
rates which ranged from 7.75% to 9.63%, with a weighted average rate of 8.69%.
In connection with the Offering, the interest rates were adjusted to market
rates for specified periods of time and currently range from 6.31% to 8.30%. As
of December 31, 1998, the weighted average interest rate was 7.12%. Including
the amortization of deferred financing costs, the all-in interest rate was
8.30%. The interest reduction periods expire prior to or at the loan maturity
dates and range from 2000 to 2008.
 
     MORTGAGE NOTES PAYABLE TO THE IRVINE COMPANY: Two of the Operating
Partnership's apartment communities are financed by mortgage notes payable to
The Irvine Company. These mortgage notes totaled $49,517 and $50,397 at December
31, 1998 and 1997, respectively. The mortgage notes are collateralized by
all-inclusive trust deeds on each of the apartment communities financed. They
bore fixed interest rates of 5.75% at December 31, 1998, are fully amortizing
and mature in 2015 and 2024. Interest incurred on the mortgage notes payable to
The Irvine Company totaled $2,871, $2,920 and $2,966 for the years ended
 
                                      F-31

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                (DOLLARS IN THOUSANDS, EXCEPT PER UNIT AMOUNTS)
 
December 31, 1998, 1997 and 1996, respectively. The mortgage notes payable to
The Irvine Company "wrap around" secured first trust deed notes payable to
third-party financial institutions. The secured first trust deed notes totaled
$49,890 and $50,651 as of December 31, 1998 and 1997, respectively.
 
     TAX-EXEMPT ASSESSMENT DISTRICT DEBT: In connection with the Offering, the
Operating Partnership assumed certain tax-exempt assessment district debt of the
predecessor entity. In conjunction with the purchase of land, the Operating
Partnership assumed $2,771 in 1996 in tax-exempt assessment district debt.
Tax-exempt assessment district debt represents debt issued by municipal
government authorities to finance the construction of infrastructure and
improvements. The debt obligations are repaid by the Operating Partnership
through assessments.
 
     UNSECURED TAX-EXEMPT BOND FINANCINGS: In June 1998, the Operating
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 Operating Partnership's
existing tax-exempt mortgage debt and to pay costs associated with prepayment
penalties and the unwinding of certain swap agreements. The Operating
Partnership recorded an extraordinary item related to debt extinguishment of
$42.5 million in June 1998.
 
     UNSECURED TERM LOAN: In November 1998, the Operating Partnership placed a
$100 million unsecured term loan with two banks. The term loan is interest-only
and bears interest at LIBOR plus 1.5%. The floating rate has been fixed through
an interest rate swap agreement. The term loan is due in November 1999. The term
loan can be extended for two six-month periods if the loan is not in no default.
 
     UNSECURED NOTES PAYABLE: In October 1997, the Operating Partnership issued
$100 million aggregate principal amount of 7% senior unsecured notes pursuant to
its shelf registration statement. The notes are due on October 1, 2007. Net
proceeds from the offering of $97.9 million were used to repay indebtedness
under the Operating Partnership's line of credit. The Partnership was in
compliance with all covenant requirements at December 31, 1998.
 
     UNSECURED LINE OF CREDIT: The Operating Partnership has a $250 million
unsecured revolving credit facility that was amended in July 1998. The amended
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 Operating Partnership's senior
unsecured long-term indebtedness. Under the credit facility, the Operating
Partnership is able to borrow funds from the participating banks through a
competitive bid process to obtain a lower interest rate. The Operating
Partnership may also enter into letters of credit under the facility. Borrowings
under the credit facility, which are guaranteed by the Company, are available to
finance the Operating Partnership's ongoing rental property development,
possible acquisitions and for general working capital needs. The Company and the
Operating Partnership must comply with certain affirmative and negative
covenants, including limitations on distributions, and the maintenance of
certain net worth, cash flow and financial ratios. At December 31, 1998, the
Company and the Operating Partnership were in compliance with all of these
covenants. In 1998, the Company entered into letters of credit under the
facility totaling $29.1 million related to acquisitions. The letters of credit
reduced the remaining amount available under the line of credit. As of December
31, 1998, there were no outstanding amounts under the line of credit and $220.9
million was available under the credit facility.
 
     INTEREST RATE SWAP AGREEMENT: The Operating Partnership uses an interest
rate swap agreement to effectively convert its floating rate unsecured term loan
to a fixed-rate basis, thus reducing the impact on future income of fluctuations
in interest rates. The swap agreement terminates in 1999. The swap counterparty
is a financial institution rated AAA by Standard & Poor's. The difference to be
paid or received is accrued and included in interest expense as a yield
adjustment and the related amount payable or receivable from the counterparty is
included in accrued liabilities or other assets. Additionally, the Operating
Partnership

restructured several interest rate swaps related to the retired tax-exempt bonds
in May 1995. These transactions reduce the interest expense on unsecured
tax-exempt bond financings by approximately 30 basis points per year through
2001. At December 31, 1998, the average fixed interest rate paid to the
counterparties was 4.88% and the average variable interest rate received was
5.56%. This resulted in a net interest receivable of $56 which was settled on
January 20, 1999. Based on prevailing interest rates at December 31, 1998, the
interest rate swap agreement had a fair value of $2,762.
 
     TREASURY RATE LOCK AGREEMENTS: The Operating Partnership entered into
treasury lock agreements to hedge a planned debt offering of $100 million and
lock into a treasury rate of 5.67%. In November 1998, the Operating Partnership
terminated all of its outstanding treasury rate lock agreements because
management determined that the planned debt offering would not occur. The cost
of terminating these agreements was $7.8 million.
 
     CAPITALIZED INTEREST: The Operating Partnership capitalizes interest on
projects actively under development using qualifying asset balances and
applicable weighted average interest rates. The average qualifying asset balance
for projects under development was approximately $156.4 million, $76.6 million
and $40.0 million for the years ended December 31, 1998, 1997 and 1996,
respectively. Interest capitalized was $12,280, $5,704 and $3,151 in 1998, 1997
and 1996, respectively. Interest incurred totaled $40,102, $36,072 and $32,657
for the years ended December 31, 1998, 1997 and 1996, respectively.
 
     OTHER MATTERS: Mortgages and notes payable totaling $198,190 are subject to
prepayment penalties.

NOTE 4 -- FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts reported in the balance sheet for financial
instruments approximate their fair value except as discussed below. The fair
values of the conventional mortgage financings and the mortgage notes payable to
The Irvine Company are estimated using discounted cash flow analyses and the
Operating Partnership's current estimated borrowing rates for similar types of
borrowing arrangements. The interest rate used in the fair value calculation
ranges from 6.3% to 7.3% based on the terms of the loan. As of December 31,
1998, the fair values of the conventional mortgage financings and the mortgage
notes payable to The Irvine Company were $135,938 and $43,432, respectively. The
fair values of the unsecured notes payable and unsecured tax-exempt bond
financings based on prevailing interest rates at December 31, 1998 were $89,096
and $339,886, respectively.
 
NOTE 5 -- REDEEMABLE PREFERRED INTERESTS
 
     In January 1998, IAC Capital 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
Operating Partnership. The Operating Partnership used the $150 million of
proceeds, net of costs and offering expenses, all of which were paid by the
Operating Partnership, to repay the outstanding balance on the Operating
Partnership's credit facility and to fund development.

                (DOLLARS IN THOUSANDS, EXCEPT PER UNIT AMOUNTS)
 
     In November 1998, the Operating Partnership issued 2.0 million of 8 3/4%
Series B Preferred Limited Partner Units. The Operating Partnership used the net
proceeds to reduce the outstanding balance on its unsecured line of credit.
 
NOTE 6 -- PARTNERS' CAPITAL
 
     In July 1996, the Company completed the sale of 1.49 million shares of
common stock at $20.125 per share. The proceeds from this offering of $30.0
million, together with proceeds from the sale of newly issued common limited
partnership units to The Irvine Company, totaled $60.0 million. Proceeds were
used to repay $43 million of debt outstanding under the revolving credit
facility. The remaining proceeds were used to fund ongoing development programs
and for general corporate purposes.
 
     In February 1997, the Company sold 1.15 million shares of common stock at
$27.50 per share. Concurrently, The Irvine Company, pursuant to its rights under
the partnership agreement, purchased 1.39 million additional common limited
partnership units at $26.06 per unit (which is equal to the public offering
price of the common stock less an amount equivalent to the underwriting
discount) which are exchangeable for common stock on a one-for-one basis,
subject to adjustment and certain limitations. The proceeds from the two
transactions totaled $66 million and were used to repay all indebtedness
outstanding under the credit facility and for general corporate purposes,
including ongoing development activities on and off the Irvine Ranch.
 
     In May 1997, the Company filed a shelf registration statement with the
Securities and Exchange Commission providing for the issuance from time to time
of up to $350 million of common stock, preferred stock, and warrants to purchase
common stock and preferred stock. The Company plans to use the proceeds raised
from any securities issued under its shelf registration statement for general
corporate purposes, including the development of new apartment communities,
acquisitions and the repayment of existing debt. Availability under the
Company's shelf registration statement was $350 million at December 31, 1998.
Concurrently, the Operating Partnership filed a shelf registration statement
with the Securities and Exchange Commission providing for the issuance from time
to time of up to $350 million of debt securities. The Operating Partnership
plans to use the proceeds raised from any securities issued under its shelf
registration statement for general corporate purposes, including the development
of new apartment communities, acquisitions and the repayment of existing debt.
On October 1, 1997, the Operating Partnership issued $100 million aggregate
principal amount of 7% senior unsecured notes pursuant to its shelf registration
statement. Availability under the Operating Partnership's shelf registration
statement was $250 million at December 31, 1998.
 
     The Operating Partnership, pursuant to a Prospectus Supplement dated April
9, 1998, may issue from time to time up to $250 million aggregate initial
offering price of its Medium-Term Notes, Series A due nine months or more from
the date of issue. Issuances of Medium-Term Notes will reduce availability under
the Operating Partnership's Registration Statement by the amount of Medium-Term
Notes issued. Similarly, issuances of other debt securities under the Operating
Partnership's Registration Statement will reduce the amount of Medium-Term Notes
that may be issued. As of December 31, 1998, there have been no issuances of
Medium-Term Notes.

NOTE 7 -- ACQUISITION OF THOMPSON RESIDENTIAL ASSETS
 
     In February 1997, the assets of Thompson Residential Company, Inc. ("TRC"),
a privately held, Northern California-based multi-family development company
were acquired for $2 million which was paid by the issuance of 74,523 common
limited partnership units (exchangeable for common stock of the Company), using
the average closing price of the Company's common stock for the ten trading days
preceding the acquisition's closing date. In addition, TRC may be paid up to an
additional $2 million in cash or common limited partnership units if an
apartment community (The Hamptons) achieves certain performance targets. As of
December 31, 1998, the performance targets have not been achieved.
 
NOTE 8 -- LAND RIGHTS AGREEMENT WITH THE IRVINE COMPANY
 
     The Operating Partnership and The Irvine Company are parties to an
exclusive land rights and non-competition agreement (the "Land Rights
Agreement"). This agreement, which extends through July 31, 2020, provides the
Operating Partnership the exclusive right, but not the obligation, to acquire
additional land sites which have been entitled for residential use and
designated by The Irvine Company as ready for apartment development in
accordance with the Master Plan. The determination to exercise an option with
respect to a site is made solely by a majority of a committee of independent
directors of the Company, whose members are unaffiliated with The Irvine
Company. In addition, The Irvine Company and its chairman,

     Under terms of the Land Rights Agreement, through July 31, 2000, the

     Options to purchase 333,000 and 51,000 shares of the Company's common
stock, the cost of which is borne by the Operating Partnership, were outstanding
during 1998 and 1997, respectively, but were not included in the computation of
diluted earnings per unit because the options' exercise price was greater than
the average market price of the common shares and, therefore, the effect would
be antidilutive.
 
     In January 1998, the Trust issued 6.0 million of 8 1/4% Series A Preferred
Securities. The proceeds were used to purchase an equivalent amount of 8 1/4%
Series A Preferred Limited Partner Units in the Operating Partnership. Income
will be allocated to the Series A Preferred Limited Partner Unit Holders at an
annual rate of 8 1/4%.
 
     In November 1998, the Operating Partnership issued 2.0 million of 8 3/4%

     EQUITY COMPENSATION PLANS: The Operating Partnership applies APB Opinion
No. 25 and related interpretations in accounting for its equity compensation
plans as described above. Accordingly, no compensation cost has been recognized
for its stock option plans. Compensation cost for the Company's other stock-
based compensation plans has been determined utilizing the fair value of the
award over the service period. Had the Operating Partnership applied FAS
Statement No. 123 for stock-based compensation, it would have resulted in net
income and earnings per share amounts that approximate the amounts reported.
Under FAS Statement No. 123, the fair value for options was estimated at the
date of grant using a Black-Scholes option pricing model with the following
weighted average assumptions for 1998, 1997 and 1996, respectively: risk-free

NOTE 12 -- SAVINGS PLAN
 
     Effective January 1, 1994, the Company implemented a defined contribution
401(k) benefit plan covering substantially all employees who have satisfied
minimum age and service requirements. The Operating Partnership matches employee
contributions up to 50%, within certain limits, which are accrued as incurred.
The Operating Partnership also makes contributions to this plan for each
participant generally equal to 3% of the participant's base salary. The
aggregate cost of these contributions by the Operating Partnership was $178,
$125 and $122 in 1998, 1997 and 1996, respectively.

NOTE 13 -- AGREEMENTS, COMMITMENTS AND CONTINGENCIES
 
     MANAGEMENT AGREEMENT: The Company has a management agreement with IAMC
whereby IAMC has the exclusive right to manage all of the Company's properties
located on the Irvine Ranch and, to the extent practical, any other properties.
Management fees range from $15/unit/month to $28/unit/month depending on whether
the property is in lease-up or stabilized. The agreement expires in March 2001.
 
     LITIGATION: The Operating Partnership is party to various legal actions
which are incidental to its business. Management believes that these actions
will not have a material adverse effect on the Operating Partnership's
consolidated financial statements.
 
     ASSESSMENT DISTRICTS: In some of the local jurisdictions within Orange
County where the predecessor entity developed property, assessment districts
were formed by local governments to finance major infrastructure improvements.
At December 31, 1998, the Operating Partnership had $37.9 million of assessment
district debt, of which $21.3 million was reflected in the balance sheet.
 
     EXCHANGE RIGHTS: The Irvine Company and certain of its affiliates have the
right to exchange up to one-third of the total common limited partnership units
owned by them for shares of common stock in each twelve-month period commencing
on December 8 of each year at an exchange ratio of one-to-one, subject to
adjustment in certain events. These exchanges are subject to certain
restrictions including percentage ownership limits.
 
     COMPANY'S OBLIGATION TO PURCHASE TENDERED PARTNERSHIP UNITS: The Irvine
Company and certain of its affiliates have the right to sell to the Company for
cash generally up to one-third of its common limited partnership units in each
twelve-month period commencing on December 8 of each year. These sales are
subject to certain restrictions. The Company is to purchase the tendered
interests at a purchase price equal to the average of the daily market prices
for the common stock of the Company for the ten consecutive trading days
immediately preceding the date of receipt by the Company of a notice of cash
tender. The Company is to pay for these interests solely with the net proceeds
of an offering of the Company's common stock. The Company would bear the costs
of sale (other than underwriting discounts and commissions). The Irvine Company
and certain of its affiliates would bear all market risk if the market price at
closing was less than the purchase price as determined on the date of tender.
Any proceeds of the offering in excess of the purchase price would be for the
sole benefit of the Company.
 
     RENT RESTRICTIONS: As of December 31, 1998, 18.1% of the apartment units
within the Operating Partnership's portfolio were required to be set aside for
residents within certain income levels and had limitations on the rent that
could be charged to such tenants. The rental revenue from five of these projects
includes governmental rent subsidy payments of $3,921, $3,903 and $3,977 for the
years ended December 31, 1998, 1997 and 1996, respectively.
 
NOTE 14 -- ACQUISITION OFFER FROM THE IRVINE COMPANY
 
     On February 1, 1999, the Company and TIC Acquisition LLC, a wholly-owned
subsidiary of The Irvine Company, entered into a definitive merger agreement
providing for the acquisition by TIC Acquisition LLC of all the outstanding
common shares of the Company in a business combination for $34 per share in
cash.

                       IRVINE APARTMENT COMMUNITIES, L.P.
 
                         REPORT OF INDEPENDENT AUDITORS
 
To the Partners
Irvine Apartment Communities, L.P.
 
     We have audited the accompanying consolidated balance sheets of Irvine
Apartment Communities, L.P., a Delaware limited partnership, as of December 31,
1998 and 1997, and the related consolidated statements of operations, changes in
partners' capital and cash flows for each of the three years in the period ended
December 31, 1998. Our audits also included the financial statement schedule on
pages F-44 to F-46. These financial statements and schedule are the
responsibility of management. Our responsibility is to express an opinion on
these financial statements and schedule based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Irvine

                               IAC CAPITAL TRUST
 
                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 -- ORGANIZATION AND BASIS OF PRESENTATION
 
     IAC Capital Trust (the "Trust") is a business trust formed on October 31,
1997 under the Delaware Business Trust Act. Irvine Apartment Communities, Inc.
(the "Company") and certain members of management of the Company acquired all of
the common securities of the Trust, representing common undivided beneficial
interests in all of the assets of the Trust, for an aggregate consideration of
$5,000.
 
     The Trust is a limited purpose financing vehicle established by the Company
and Irvine Apartment Communities, L.P. (the "Operating Partnership") and exists
for the sole purpose of issuing redeemable preferred securities and investing
the proceeds thereof in redeemable preferred limited partner units of the
Operating Partnership. The redeemable preferred securities have no voting rights
except in limited circumstances. The Trust's declaration does not permit the
incurrence by the Trust of any indebtedness for borrowed money or the making of
any investment other than in the redeemable preferred limited partner units of
the Operating Partnership.
 
     The Operating Partnership pays all obligations (other than with respect to
the Trust securities) and all costs and expenses of the Trust, including the
fees and expenses of the trustees and any income taxes, duties and other
governmental charges.
 
NOTE 2 -- REDEEMABLE PREFERRED INTEREST
 
     There are 6.0 million redeemable preferred securities outstanding that bear
an annual cash distribution rate of 8 1/4% which is paid quarterly. The
redeemable preferred securities have a stated maturity of December 31, 2092.
 
NOTE 3 -- INVESTMENT IN IRVINE APARTMENT COMMUNITIES, L.P.
 
     The proceeds from the issuance of redeemable preferred securities were
invested in redeemable preferred limited partner units of the Operating
Partnership which bear an annual cash distribution rate of 8 1/4% which is paid
quarterly. The Trust accounts for its investment in the Operating Partnership
using the equity method of accounting.
 
NOTE 4 -- INCOME TAXES
 
     The Company has elected to be taxed as a REIT and, as such, will generally
not be subject to federal and state income taxation at the corporate level. To
maintain its REIT status, the Trust is required to distribute annually at least
95% of its REIT taxable income to its shareholders and to satisfy certain other
requirements. Accordingly, no provision has been made for federal income taxes
in the accompanying statements of operations.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Trustees
IAC Capital Trust
 
     We have audited the accompanying balance sheet of IAC Capital Trust, a
Delaware Business Trust, as of December 31, 1998 and the related statements of
operations, changes in equity and cash flows for the period January 20, 1998
(commencement of operations) through December 31, 1998. These financial
statements are the responsibility of management. Our responsibility is to
express an opinion on these financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of IAC Capital Trust at
December 31, 1998 and the results of its operations and its cash flows for the
period January 20, 1998 (commencement) through December 31, 1998, in conformity
with generally accepted accounting principles.

                            STOCK PURCHASE AGREEMENT


                  THIS STOCK PURCHASE AGREEMENT is made as of February ___,
1999, by and between IRVINE APARTMENT COMMUNITIES, L.P., a Delaware limited
partnership, and/or one or more nominees (collectively, "IACLP"), as buyer, and
WILLIAM W. THOMPSON ("THOMPSON"), BRUCE DORFMAN ("DORFMAN") and ROBERT HUGHES
("HUGHES"), as sellers. Thompson, Dorfman and Hughes shall sometimes hereinafter
be individually referred to as a "SELLER" and collectively referred to as
"SELLERS".


                                    RECITALS

                  IACLP desires to acquire from each of the Sellers, and each of
the Sellers desires to sell to IACLP, the shares of TRC owned, respectively, by
such Seller.

                  NOW, THEREFORE, in consideration of the mutual promises and
undertakings set forth herein and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereto
agree as follows:

                  SECTION 1. AGREEMENT TO SELL. Subject to the terms and
conditions set forth herein, each of the Sellers hereby agrees to sell to IACLP,
and IACLP hereby agrees to purchase from each of the Sellers, all of such
Seller's right, title and interest in the issued and outstanding shares of TRC
owned by such Seller (such shares, in the aggregate, shall be hereinafter
collectively referred to as the "SHARES") for such Seller's respective share of
the Purchase Price (as hereinafter defined). As used herein, the term "PURCHASE
PRICE" shall be an amount equal to $4,533,782.00. The Purchase Price shall be
distributed to each of the Sellers, on a pro rata basis, based upon the Shares
of TRC owned by such Seller.

                  SECTION 2. CLOSING. The closing (the "CLOSING") of the
purchase of the Shares shall take place immediately after the merger of Irvine
Apartment Communities, Inc., a Maryland corporation ("IAC"), with and into an
affiliate of The Irvine Company, a Delaware corporation (the "ACQUISITION"). If
the Acquisition does not occur by December 31, 1999, then either IACLP or the
Sellers may terminate this Agreement by delivery of written notice to the other.

                  SECTION 3. IACLP CONDITIONS PRECEDENT TO CLOSING. IACLP's
obligation to purchase the Shares shall be subject to satisfaction of the
following conditions precedent:

                  (a) the closing of the Acquisition shall have occurred (in the
event that IACLP determines that the Acquisition will not occur, IACLP may
terminate this Agreement by the delivery of written notice to the Sellers),

                  (b) each of the representations and warranties made by the
Sellers shall be true and correct as of the date when made and as of the
Closing,


                                       1
<PAGE>   2

                  (c) IACLP shall have received (1) a certificate or
certificates representing 1,250 Shares (the "CERTIFICATES"), free and clear of
any lien, security interest, encumbrance, claim or right of another
(collectively, "ENCUMBRANCE"), duly endorsed by the owner thereof, and (2) such
evidence as IACLP may require that the spouses of each of the Sellers have
consented to the sale of the Shares owned by such Seller and fully and
completely released any interest such spouse may have in such Shares.

                  SECTION 4. SELLERS' CONDITIONS PRECEDENT TO CLOSING. Sellers'
obligation to sell the Shares to IACLP shall be subject to the payment by IACLP
of the Purchase Price.

                  SECTION 5. SELLERS' REPRESENTATIONS, WARRANTIES AND COVENANTS.
In consideration of IACLP's agreement to purchase the Shares, each of the
Sellers hereby, jointly and severally, represents, warrants and covenants as
follows:

                  (a) The entire authorized stock of TRC consists of 10,000
shares of common stock of which 1,250 shares are issued and outstanding. All of
the issued and outstanding shares have been duly authorized and validly issued
and are fully paid and nonassessable. There are no outstanding or authorized
options, warrants, rights, contracts, rights to subscribe, conversion rights or
other agreements or commitments to which TRC or any of the Sellers are parties
or which are binding upon TRC or any of the Sellers providing for the issuance
or acquisition of the stock of TRC which would be binding upon IACLP or would
otherwise affect the transaction contemplated by this Agreement. There are no
outstanding or authorized stock appreciation, phantom stock or similar rights
with respect to TRC which would be binding upon IACLP or would otherwise affect
the transaction contemplated by this Agreement.

                  (b) Thompson owns, beneficially and of record, 1,000 Shares,
free and clear of all Encumbrances; Dorfman owns, beneficially and of record,
125 Shares, free and clear of all Encumbrances; and Hughes owns, beneficially
and of record, 125 Shares, free and clear of all Encumbrances. The delivery of
the Certificates to IACLP will result in IACLP's immediate acquisition, of
record and of beneficial ownership, of all of the issued and outstanding Shares
of TRC, free and clear of any Encumbrance, and with all rights of ownership
associated therewith.

                  (c) TRC was formed on December 22, 1995. TRC timely elected to
be a Subchapter S corporation under Section 1362 of the Internal Revenue Code of
1986, as amended (the "CODE"), and comparable provisions of state law, with
respect to its first tax reporting year, and has not, at any time thereafter
through the date of Closing, revoked such election. TRC is not aware of any
action taken or not taken by it which has caused or would cause TRC not to
qualify as a Subchapter S corporation under the Code and comparable provisions
of state law.

                  (d) The assets listed on Schedule 1 attached hereto and
incorporated herein by this reference (the "ASSETS") are owned by TRC free and
clear of all Encumbrances. Since the contribution of certain of its assets to
IACLP pursuant to the Contribution Agreement (as defined in Schedule 1), TRC has
conducted no business other than such business as is incidental to its ownership
of the Assets, and has had no employees. Except for the Assets, TRC has no
assets 


                                       2
<PAGE>   3

other than its corporate books and records, its corporate franchise and its
corporate bank accounts.

                  (e) All tax returns and all information returns for all
periods ending on or before the date of the Closing that were, are or will be
required to be filed by, or with respect to, TRC have been or will be filed on a
timely basis in accordance with the laws, regulations and administrative
requirements of the applicable taxing authority. All such tax returns and all
information returns were, when filed, and continue to be, true, correct and
complete. There are no outstanding extensions to file any tax return. TRC has
paid or, if not yet due and payable, will pay when due all income, franchise,
property, employee-related and any and all other taxes, fees and assessments of
whatever kind or nature, including any interest or penalties thereon, that
relate to periods through the date of the Closing. TRC has not been audited by
any taxing authority, nor has TRC or any of its shareholders been notified of
any such audit.

indemnified party in connection with such defense, and (ii) the indemnifying
party shall, at reasonable intervals, keep the indemnified party advised as to

                         THE SECOND AMENDED AND RESTATED
                        AGREEMENT OF LIMITED PARTNERSHIP
                          (THE "PARTNERSHIP AGREEMENT")
                               OF THE PARTNERSHIP

                        DESIGNATION OF THE VOTING POWERS,
                          DESIGNATIONS, PREFERENCES AND
                      RELATIVE, PARTICIPATING, OPTIONAL OR
                    OTHER SPECIAL RIGHTS AND QUALIFICATIONS,
                       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 are 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
<PAGE>   2
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>   3
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 for 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>   5
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 holder 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 as 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 Units will no longer be deemed to be outstanding and all rights of
holders of such Series


                                       5
<PAGE>   6
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>   7
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(b) 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 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 to
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 by-laws), 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>   8

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 holder 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 than 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>   9
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>   10
         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>   11
         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


                                       11
<PAGE>   12
         following the receipt of the Exchange Notice, (B) the redemption price,
         (C) the place or places where the Series B Preferred Limited Partner
         Units are to be 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 cause the Partnership to redeem
         all of the Series B Preferred Limited Partner Units then outstanding in
         exchange for cash, a Redemption Notice. Series B 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 SECURITIES LAWS AND MAY NOT BE OFFERED OR SOLD
                  UNLESS THEY HAVE BEEN REGISTERED UNDER SUCH ACT AND


                                       12
<PAGE>   13
                  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.

                            CONFIDENTIALITY AGREEMENT

                               AND GENERAL RELEASE

        This CONFIDENTIALITY AGREEMENT AND GENERAL RELEASE (hereafter
"Agreement") is entered into by Irvine Apartment Communities, Inc. ("Company")
and James Mead (MEAD).

        1. MEAD hereby tenders his voluntary resignation from the Company, which
will be implemented in accordance with the terms of this agreement.

        2. From October 1, 1998 to February 1, 1999, MEAD will continue to be
employed as a regular employee of the Company, will continue to receive his
present monthly salary, will continue to participate in all of the benefit plans
for which he and other Company executives are eligible, and will perform his
normal executive duties and/or other duties consistent with his CFO position as
assigned by the President or the Board of Directors. MEAD understands that the
Company will begin an active search for a new CFO, and MEAD agrees to cooperate
as requested in the transition process, including the probability that the new
CFO would begin work prior to February 1, 1999. Throughout the time period up to
February 1, 1999, MEAD agrees to work in a professional and cooperative manner
to make this transition work as smoothly as possible.

        3. On or about February 1, 1999, the following will occur:

             a. MEAD will return to the Company all files, records, credit
cards, keys, equipment, and any other property or documents maintained by him
which relate to the Company or its owners, directors, employees, or related
entities.

             b. A cash bonus payment of $165,000, less legally required
deductions, will be paid to MEAD.

             c. A payment of $375,000, less legally required deductions, will be
provided to MEAD.

             d. Vesting of restricted stock awards, vesting of stock options and
dividend equivalent payments for MEAD shall all cease on February 1, 1999,
regardless of any extension of his employment status as described in paragraph
4. Payment for restricted stock which vests in 1998 will be provided to MEAD by
check (not in the form of shares) in February or March, 1999. Payment for
restricted stock which vests in 1999 (through February 1) will also be provided
to MEAD by check (not in the form of shares) in February or March, 1999 and the
payment amount will assume that FAD targets for the 100% vesting level are
achieved in 1999. In addition, vested stock options will remain exercisable
until 90 days following MEAD's employment termination date.

        4. MEAD's employment will cease on February 1, 1999, unless he is on
short-term disability status on February 1, 1999, in which case, his employment
will continue and will not terminate until he is released from short-term
disability status for any reason (e.g., recovery, conversion to LTD, expiration
of short-term disability benefits). During this period, the Company will
continue MEAD on the payroll at his present salary and provide continued
benefits after February 1, 1999 (except no additional vacation accrual after the
first thirty days on disability status), but payroll costs after February 1 will
be subtracted from the six month consulting payment described in paragraph 5a,
so that payroll costs after February 1, 1999 and the consulting payments will
not exceed $125,000 in total.

        5. MEAD will be retained as a consultant to the Company for a period of
six months following the termination of his employment. During the six months,
MEAD may be employed or retained as an employee or consultant to other persons
or companies, but will remain available to provide consulting services as
requested in a professional and timely manner to the Company for a maximum of
thirty hours in total for the six month period. Such services will be similar in
kind to the expertise MEAD provided to the Company during the period of his
employment. If any material is needed by him in order to perform any requested
consulting service, it will be provided to him and promptly returned by him.

             a. For such services, MEAD will be paid $20,833 per month retainer,
payable on or about the first day 

<PAGE>   2

of the month commencing on the first day of the month following the termination
of his employment, andcontinuing monthly thereafter until payments totaling
$125,000 have been made (including any costs under paragraph 4). The payroll
costs for MEAD after February 1 described in paragraph 4 shall be deducted as
they occur from each month's retainer.

        6. MEAD will also receive the following payments and benefits:

             a. The Company will reimburse reasonable expenses incurred by MEAD
(telephone, travel, etc.) which are necessarily incurred and approved in advance
in the performance of his consulting services requested by the Company under
this agreement.

             b. Group insurance coverage pursuant to the terms of the Company's
group insurance plans will be continued at the Company's expense through
February 28, 1999 at which time MEAD may continue such insurance if he desires
in accordance with the provisions of such plans. If MEAD's employment is
continued beyond February 1, as outlined in paragraph 4, then his insurance
coverage shall continue until the last day of the month in which his employment
is terminated. In addition, the Company agrees not to make any public
announcements which refer to MEAD's medical condition.

             c. MEAD will continue to be covered by the Company's Directors' and
Officers' Insurance in accordance with the terms of such policy through MEAD's
consulting period and thereafter.

         7. MEAD promises not to disparage the Company or its owners, directors,
officers, employees, or related entities and not to use or disclose to any
person or entity in any manner any personal, financial or confidential
information or trade secrets related to the Company, its owners, directors,
officers, employees, or related entities which he learned while employed by the
Company, and further promises not to disclose to anyone (other than his spouse
and tax/legal advisor) the terms of this Agreement or the fact or amount of any
payment made by the Company in settlement of MEAD's claims. MEAD also promises
not to solicit or participate in or assist in any way in the solicitation of any
Company employee to cease employment with the Company, and the customers of the
Company to cease or decrease doing business with the Company or to do business
with any competitor of the Company for a period of twelve months following
February 1, 1999. Nothing in this provision will be construed as a prohibition
from MEAD working during the consulting period referred to in paragraph 5 or
thereafter as an executive of any company, whether competing or not.

         8. In exchange for the payments and benefits provided in this
agreement, MEAD hereby unconditionally releases and forever discharges the
Company and its related or successor companies, its owners, directors, officers,
employees, representatives and agents, from any and all claims, (including, but
not limited to, any claims under any state or federal statutes or public
policies relating to discrimination or any other subjects), liabilities,
demands, losses and expenses (including attorneys' fees) of any nature
whatsoever, known or unknown, including, but not limited to, his employment
relationship or termination, which he now has or may have in the future based on
any act or omission which occurred prior to the date MEAD signs this Agreement.
MEAD agrees that his rights hereafter are governed by this Agreement. MEAD
expressly waives and relinquishes all rights and benefits afforded by Section
1542 of the California Civil Code, and does so understanding and acknowledging
the significance of such specific waiver of section 1542. Section 1542 states as
follows:

"A general release does not extend to claims which the creditor does not know
or suspect to exist in his favor at the time of executing the release, which if
known by him must have materially affected his settlement with the debtor."

The Company hereby releases MEAD from any claims of any kind based on any facts
known to the Company's Board of Directors at this time.

        9. Should MEAD breach any of his obligations in this Agreement
(including, but not limited to, paragraphs 2,7 and 8), payments under this
Agreement shall stop in addition to any other legal or equitable remedies the
Company may pursue.

        10. This Agreement contains all of the terms, promises, representations,
and understandings made between the parties. MEAD agrees that no promises,
representations, or inducements have been made to him other than those which are
expressly set forth herein. MEAD acknowledges and agrees that he has had
sufficient opportunity to fully and privately review this document prior to its
execution, and has had ample opportunity to consult an attorney in connection
therewith, if he so desired.

        11. This Agreement will be interpreted in accordance with the laws of
the State of California. Any dispute arising hereafter between the parties
regarding this Agreement or MEAD's employment or otherwise (except any claim
against any insurer for benefits under any insurance plan referenced herein)
shall be resolved by an experienced employment arbitrator selected in accordance
with the employment rules and procedures of the American Arbitration
Association. Should MEAD or the Company pursue any other legal or administrative
action, the other party shall be entitled to recover all costs, expenses, and
attorneys' fees it incurs as a result of such action.

Gentlemen:

               In connection with that certain Agreement and Plan of Merger,
dated as of February 1, 1999 (the "Merger Agreement"), between TIC Acquisition
LLC ("Acquiror") and Irvine Apartment Communities, Inc. (the "Company"), you
have requested that The Irvine Company ("TIC") make certain representations,
warranties and covenants. In order to facilitate the transactions contemplated
by the Merger Agreement, TIC hereby makes the representations, warranties and
covenants set forth in this letter agreement. All capitalized terms not defined
herein shall have the meanings set forth in the Merger Agreement.

               1. Ownership of Acquiror/Availability of Funds. All of Acquiror's
membership interests are owned by TIC and a wholly-owned Subsidiary of TIC. TIC
is the sole managing member of Acquiror. TIC shall take no action that would
cause Acquiror not to have a minimum of $150 million of cash on hand from the
date of the Merger Agreement through the earlier of (i) the Effective Time and
(ii) sixty (60) days following the termination of the Merger Agreement pursuant
to the terms thereof. Prior to the earlier of (i) the Effective Time and (ii)
sixty (60) days following the termination of the Merger Agreement pursuant to
the terms thereof, TIC shall not permit Acquiror to engage in any business or
transaction other than business or transactions related to the transactions
contemplated by the Merger Agreement.

               2. Ownership of Stock. From the date hereof to the earlier of (i)
the Effective Time and (ii) the termination of the Merger Agreement pursuant to
the terms thereof, TIC shall not, and shall not permit any of its Subsidiaries
to, sell or otherwise dispose of any of the shares of Company Common Stock owned
by them. At the Company Stockholders Meeting, or any adjournment thereof, TIC
shall, and shall cause its Subsidiaries to, vote the shares of Company Common
Stock owned by them in favor of the Merger.

               3. Cooperation. TIC shall take all actions necessary to cooperate
with Acquiror, and shall take all actions necessary to cause Acquiror to comply
with its obligations, in connection with Sections 5.1(a), 5.8 and 5.9 (insofar
as it pertains to insurance only) of the Merger Agreement; provided that with
respect to Section 5.9 of the Merger Agreement, TIC shall be deemed to have
satisfied its obligations hereunder (and the obligations of Acquiror under the




<PAGE>   2

Merger Agreement) by causing Acquiror to purchase an appropriate policy of
insurance. TIC agrees to cooperate with Acquiror and the Company in connection
with the Merger Agreement and to use reasonable efforts to cause Acquiror to
consummate the Merger; provided that TIC shall have no obligation to contribute
any funds to Acquiror in connection with the Merger.

               The rights and obligations of the parties to this letter
agreement shall bind and inure to the benefit of the respective successors and
assigns of the parties hereto.

               This letter agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, without giving effect to
conflicts of law principles.

               This letter agreement constitutes the full and complete
understanding and agreement of the parties hereto and supersedes all prior
understandings and agreements with respect to the subject matter hereof. Any
waiver, modification or amendment of any provision of this letter agreement
shall be effective only if in writing and signed by the parties hereto.

               "LIBOR Reserve Percentage" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) under
Regulation D, as Regulation D may be amended, modified or supplemented, for
determining the maximum reserve requirement for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of "Eurocurrency liabilities" (or in respect of any other category of
liabilities which includes deposits by reference to which the interest rate on
LIBOR Loans is determined or any category of extensions of credit or other

respect of all Loans, shall bear interest at the Default Rate.

               (c) The Administrative Agent shall determine each interest rate
applicable to the Loans hereunder. The Administrative Agent shall give prompt

               (b) Fees Non-Refundable. All fees set forth in this Section 2.5
shall be deemed to have been earned on the earlier of when accrued or when
payable hereunder and shall be non-refundable. The obligation of the Borrower to
pay such fees in accordance with provisions hereof shall be binding upon the
Borrower and shall inure to the benefit of the Administrative Agent and the
Banks regardless of whether any Loans are actually made.

               SECTION 2.6. Maturity Date. The entire principal balance of the
Loans (together with accrued and unpaid interest thereon) and all other
Obligations hereunder shall be due and payable on the Maturity Date. All

               SECTION 2.7.  First Option To Extend.

               The Borrower shall have the option to extend the term of the

               (a) The Borrower shall provide the Administrative Agent with
written notice of the Borrower's request to exercise the First Option to Extend

               (b) As of the date of the Borrower's delivery of notice of
request to exercise the First Option to Extend, and as of the Original Maturity
Date, no Event of Default shall have occurred and be continuing, and the
Borrower shall so certify in writing; and



                                       24
<PAGE>   32

               (c) On or before the Original Maturity Date, the Borrower shall
pay to the Administrative Agent on behalf of the Banks an extension fee in the
amount of One Hundred Fifty Thousand Dollars ($150,000.00).

               SECTION 2.8.  Second Option To Extend.

               The Borrower shall have the option to extend the term of the

               (d) The Borrower shall have previously exercised the First Option
to Extend in accordance with the terms of Section 2.7 hereof.

               SECTION 2.9.  Lockout; Optional Prepayments.

               (a) During the Initial Term, the Borrower shall have no right to
prepay all or any portion of the principal amount of any Loan (excluding payment
in full on the Maturity Date). After the Initial Term, if the Maturity Date is
extended as herein provided, the Borrower may prepay the Loans in accordance
with Sections 2.9(b) and (c) below.

               (b) The Borrower may, upon at least one (1) Domestic Business
Day's notice to the Administrative Agent, prepay any Base Rate Loans, in whole
or in part at any time, or from time to time in part in amounts aggregating Five
Hundred Thousand Dollars ($500,000) or any larger multiple of One Hundred
Thousand Dollars ($100,000), by paying the principal amount thereof. Each such
optional prepayment shall be applied to prepay ratably the Loans of the several
Banks included in such Borrowing.

               (c) Except as provided in Article VIII and except with respect to
any LIBOR Loan which has been converted to a Base Rate Loan pursuant to Sections
8.1, 8.2 or 8.5 hereof, the Borrower may not prepay all or any portion of the
principal amount of



                                       25
<PAGE>   33

any LIBOR Loan prior to the end of the Interest Period applicable thereto unless
the Borrower shall also pay any applicable expenses pursuant to Section 2.11.
The Borrower shall provide at least three (3) LIBOR Business Days' notice to the
Administrative Agent prior to any such optional prepayment. Each such optional
prepayment shall be in the amounts set forth in Section 2.9(b) above, except
that any LIBOR Loan which has been converted to a Base Rate Loan pursuant to
Sections 8.1, 8.2 or 8.5 hereof may be prepaid without ratable payment of other
Loans which have not been so converted.

               (d) In no event shall any amounts prepaid be reborrowed.

               SECTION 2.10.  General Provisions as to Payments.

               (a) The Borrower shall make each payment of interest and
principal on the Loans and of fees hereunder, not later than 10:00 A.M. (San
Francisco time) on the date when due, in Federal or other funds immediately
available in San Francisco, to the Administrative Agent at its address referred
to in Section 9.1. The Administrative Agent will promptly (and in any event
within one (1) Domestic Business Day after receipt thereof) distribute to each
Bank its ratable share of each such payment received by the Administrative Agent
for the account of the Banks. If and to the extent that the Administrative Agent
shall receive any such payment for the account of the Banks on or before 10:00
A.M. (San Francisco time) on any Domestic Business Day, and Administrative Agent
shall not have distributed to any Bank its applicable share of such payment on
such Domestic Business Day, Administrative Agent shall distribute such amount to
such Bank together with interest thereon, for each day from the date such amount
should have been distributed to such Bank until the date Administrative Agent
distributes such amount to such Bank, at the Federal Funds Rate. Whenever any
payment of principal of, or interest on the Base Rate Loans or of fees shall be
due on a day which is not a Domestic Business Day, the date for payment thereof
shall be extended to the next succeeding Domestic Business Day. Whenever any
payment of principal of, or interest on, the LIBOR Loans shall be due on a day
which is not a LIBOR Business Day, the date for payment thereof shall be
extended to the next succeeding LIBOR Business Day unless such LIBOR Business
Day falls in another calendar month, in which case the date for payment thereof
shall be the next preceding LIBOR Business Day. If the date for any payment of
principal is extended by operation of law or otherwise, interest thereon shall
be payable for such extended time.

               (b) Unless the Administrative Agent shall have received notice
from the Borrower prior to the date on which any payment is due to the Banks
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Bank on such due
date an amount equal to the amount then due such Bank. If and to the extent that
the Borrower shall not have so made such payment, each Bank shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Bank
together with interest thereon, for each day from the date such



                                       26
<PAGE>   34

amount is distributed to such Bank until the date such Bank repays such amount
to the Administrative Agent, at the Federal Funds Rate.

               SECTION 2.11. Funding Losses. If the Borrower makes any payment
of principal with respect to any LIBOR Loan (pursuant to Article II, VI or VIII
or otherwise) on any day other than the last day of the Interest Period
applicable thereto, or if the Borrower shall deliver a Notice of Interest Period
Election specifying that a LIBOR Loan shall be continued on a date other than
the last day of the then current Interest Period applicable thereto, the
Borrower shall reimburse each Bank within fifteen (15) days after certification
of such Bank of such loss or expense (which shall be delivered by each such Bank
to Administrative Agent for delivery to Borrower) for any resulting loss or
expense incurred by it (or by an existing Participant in the related Loan),
including (without limitation) any loss incurred in obtaining, liquidating or
employing deposits from third parties, but excluding loss of margin for the
period after any such payment, provided that such Bank shall have delivered to
Administrative Agent and Administrative Agent shall have delivered to the
Borrower a certification as to the amount of such loss or expense, which
certification shall set forth in reasonable detail the basis for and calculation
of such loss or expense and shall be conclusive in the absence of demonstrable
error.

               SECTION 2.12. Computation of Interest and Fees. All interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

               SECTION 2.13. Use of Proceeds. The Borrower shall use the
proceeds of the Loans for general corporate purposes, including, without
limitation, the acquisition of multifamily apartment projects and real property
to be used in connection with construction, management, development, acquisition
and operation of multifamily apartment projects and for general working capital
needs of the Borrower.

               SECTION 2.14. Method of Electing Interest Rates. (a) The Loans
included in the initial Borrowing shall bear interest initially at the interest
rate(s) applicable thereto pursuant to Section 2.4 hereof during the Interest
Period(s) specified by the Borrower in the initial Notice of Interest Period
Election. Thereafter, the Borrower may from time to time elect to change or
continue the Interest Period(s) applicable to the LIBOR Loans, or the applicable
portions thereof (subject in each case to the provisions of Article VIII), as
follows:

               (i) if such Loans are LIBOR Loans, the Borrower may elect to
continue all or any portion of such Loans as LIBOR Loans for an additional
Interest Period or additional Interest Periods, in each case effective on the
last day of the then current Interest Period applicable to such Loans, or on
such other date designated by Borrower in the Notice of Interest Period Election
provided Borrower shall pay any losses pursuant to Section 2.11.



                                       27
<PAGE>   35

               Each such election shall be made by delivering a notice in the
form of Exhibit "C" (a "Notice of Interest Period Election") to the
Administrative Agent by 11:00 A.M. (San Francisco time) at least three (3) LIBOR
Business Days before the continuation is to be effective. A Notice of Interest
Period Election may, if it so specifies, apply to only a portion of the
aggregate principal amount of the LIBOR Loans; provided that (i) such portion is
allocated ratably among all LIBOR Loans, (ii) there shall be no more than five
(5) LIBOR fixings outstanding at any time, and (iii) no Interest Period shall
extend beyond the Maturity Date.

               (b)    Each Notice of Interest Period Election shall specify:

                     (i)  the portion of the LIBOR Loans to which such notice
applies;

                    (ii)  the date on which the continuation is to be effective,
which shall comply with the terms of subsection (a) above; and

                   (iii)  if such Loans are to be continued as LIBOR Loans for
an additional Interest Period, the duration of such additional Interest Period,
which shall comply with the terms of subsection (a) above.

Each Interest Period specified in a Notice of Interest Period Election shall
comply with the provisions of the definition of Interest Period; provided that
the Borrower may request an additional Interest Period of less than one (1)
month if and only if all of the Banks, in their sole and absolute discretion,
approve of such request.

               (c) Upon receipt of a Notice of Interest Period Election from the
Borrower pursuant to subsection (a) above, the Administrative Agent shall notify
each Bank the same day as it receives such Notice of Interest Period Election of
the contents thereof and the Interest Periods (if different from those requested
by the Borrower) and such notice shall not thereafter be revocable by the
Borrower. If the Borrower fails to deliver a timely Notice of Interest Period
Election to the Administrative Agent for the LIBOR Loans (or the relevant
portions thereof), such Loans (or the relevant portions thereof) shall be
continued as LIBOR Loans on the last day of the then current Interest Period
applicable thereto for an additional Interest Period of one (1) month; provided,
however, that if such additional Interest Period would extend beyond the
Maturity Date, then such Loans (or the relevant portions thereof) shall be
converted into Base Rate Loans on the last day of the then current Interest
Period applicable thereto. Within one LIBOR Business Day after receipt of a
Notice of Interest Period Election from the Borrower pursuant to subsection (a)
above, the Administrative Agent shall notify each Bank of the interest rates
determined pursuant thereto.

writing by Borrower to the Banks.

                                   ARTICLE IV.

                         REPRESENTATIONS AND WARRANTIES

               In order to induce the Administrative Agent and each of the other
Banks which is or may become a party to this Agreement to make the Loans, the
Borrower makes the following representations and warranties as of the Closing
Date. Such representations and warranties shall survive the effectiveness of
this Agreement, the execution and delivery of the other Loan Documents and the
making of the Loans.

               SECTION 4.1. Existence and Power. The Borrower is a limited
partnership, duly formed and validly existing as a limited partnership under the
laws of the State of Delaware and has all powers and all material governmental
licenses, authorizations, consents and approvals required to own its property
and assets and carry on its business as now conducted or as it presently
proposes to conduct and has been duly qualified and is in good standing in the
State of California and in every other jurisdiction in which the failure to be
so qualified and/or in good standing is likely to have a Material Adverse
Effect. Guarantor is a corporation, duly formed, validly existing and in good
standing as a real estate investment trust under the laws of the State of
Maryland and has all powers and all material governmental licenses,
authorizations, consents and approvals required to own its property and assets
and carry on its business as now conducted or as it presently proposes to
conduct and has been duly qualified and is in good standing in every
jurisdiction in which the failure to be so qualified and/or in good standing is
reasonably expected to have a Material Adverse Effect.

               SECTION 4.2. Power and Authority. The Borrower has the
partnership power and authority to execute, deliver and carry out the terms and
provisions of each of the Loan Documents to which it is a party and has taken
all necessary partnership action, if any, to authorize the execution and
delivery on behalf of the Borrower and the performance by the Borrower of such
Loan Documents. The Borrower has duly executed and delivered each Loan Document
to which it is a party in accordance with the terms of this Agreement, and each
such Loan Document constitutes the legal, valid and binding obligation of the
Borrower, enforceable in accordance with its terms, except as enforceability may
be limited by applicable insolvency, bankruptcy or other laws



                                       31
<PAGE>   39

affecting creditors rights generally, or general principles of equity, whether
such enforceability is considered in a proceeding in equity or at law. Guarantor
has the power and authority to execute, deliver and carry out the terms and
provisions of each of the Loan Documents on behalf of the Borrower to which the
Borrower is a party and has taken all necessary action to authorize the
execution and delivery on behalf of the Borrower and the performance by the
Borrower of such Loan Documents.

               SECTION 4.3. No Violation. Neither the execution, delivery or
performance by or on behalf of the Borrower of the Loan Documents to which it is
a party, nor compliance by the Borrower with the terms and provisions thereof
nor the consummation of the transactions contemplated by the Loan Documents, (i)
will contravene any applicable provision of any law, statute, rule, regulation,
order, writ, injunction or decree of any court or governmental instrumentality,
(ii) will conflict with or result in any breach of, any of the terms, covenants,
conditions or provisions of, or constitute a default under, or result in the
creation or imposition of (or the obligation to create or impose) any Lien upon
any of the property or assets of the Borrower or any of its Consolidated
Subsidiaries pursuant to the terms of any indenture, mortgage, deed of trust, or
other agreement or other instrument to which the Borrower (or of any partnership
of which the Borrower is a partner) or any of its Consolidated Subsidiaries is a
party or by which it or any of its property or assets is bound or to which it is
subject, or (iii) will cause a default by the Borrower under any organizational
document of any Person in which the Borrower has an interest, or cause a default
under the Borrower's agreement or certificate of limited partnership, the
consequences of any such contravention, conflict, breach or default described in
clauses (i), (ii) or (iii) is reasonably expected to have a Material Adverse
Effect, or result in or require the creation or imposition of any Lien
whatsoever upon any Property (except as contemplated herein).

               SECTION 4.4.  Financial Information.

               (a) The consolidated balance sheet of the Borrower and its
Consolidated Subsidiaries, dated as of December 31, 1997, and the related
consolidated statements of Borrower's financial position for the Fiscal Year
then ended, reported on by Ernst & Young LLP, a copy of which has been delivered
to each of the Banks, fairly present, in conformity with GAAP, the consolidated
financial position of the Borrower and its Consolidated Subsidiaries as of such
date and their consolidated results of operations and cash flows for such Fiscal
Year.

               (b) The consolidated balance sheet of Guarantor, dated as of
December 31, 1997, and the related consolidated statements of Guarantor's
financial position for the Fiscal Year then ended, reported on by Ernst & Young
LLP and set forth in the Guarantor's 1997 Form 10-K, a copy of which has been
delivered to each of the Banks, fairly present, in conformity with GAAP, the
consolidated financial position of Guarantor and its Consolidated Subsidiaries
as of such date and their consolidated results of operations and cash flows for
such Fiscal Year.



                                       32
<PAGE>   40

               (c) The unaudited consolidated balance sheet of Guarantor as at
September 30, 1998 and related statements of income, retained earnings and cash
flow for the period then ended, certified by the chief accounting officer or
chief financial officer of Guarantor, a copy of which has been delivered to
Administrative Agent, were prepared in accordance with GAAP consistently applied
(except to the extent noted therein) and fairly present the consolidated
financial position of Guarantor, Borrower and the Consolidated Subsidiaries as
of such date and the results of operations and cash flow for the period covered
thereby, subject to normal year-end adjustments. Neither Borrower, Guarantor nor
any Consolidated Subsidiary had on such date any material Contingent
Obligations, liabilities for taxes or long-term leases, unusual forward or
long-term commitments or unrealized losses from any unfavorable commitments
which are not reflected in the foregoing statements or in the notes thereto and
which are material.

               (d) Since December 31, 1997, (i) except as may have been
disclosed in writing to the Banks, nothing has occurred having a Material
Adverse Effect, and (ii) except as previously disclosed to the Banks, neither
the Borrower nor Guarantor has incurred any material indebtedness or guaranty on
or before the Closing Date.

               SECTION 4.5. Litigation. Except as previously disclosed by the
Borrower in writing to the Banks, there is no action, suit or proceeding pending
against, or to the knowledge of the Borrower threatened against or affecting,
(i) the Borrower, Guarantor or any of their Consolidated Subsidiaries, (ii) the
Loan Documents or any of the transactions contemplated by the Loan Documents or
(iii) any of their assets, before any court or arbitrator or any governmental
body, agency or official in which there is a reasonable possibility of an
adverse decision which actions, suits or proceedings described in clauses (i),
(ii) or (iii) would, individually, or in the aggregate have a Material Adverse
Effect or which in any manner draws into question the validity of this Agreement
or the other Loan Documents.

               SECTION 4.6.  Compliance with ERISA.

               (a) Except as set forth on Schedule 4.6 attached hereto, neither
Borrower nor Guarantor is a member of any Plan or Multiemployer Plan or any
other Benefit Arrangement.

               (b) The transactions contemplated by the Loan Documents will not
constitute a nonexempt prohibited transaction (as such term is defined in
Section 4975 of the Code or Section 406 of ERISA) which would, individually or
in the aggregate, have a Material Adverse Effect on Borrower or that could
subject the Administrative Agent or the Banks to any tax or penalty or
prohibited transactions imposed under Section 4975 of the Code or Section 502(i)
of ERISA.

               SECTION 4.7. Environmental Matters. The Borrower conducts reviews
of the effect of Environmental Laws on the business, operations and properties
of the Borrower and its Consolidated Subsidiaries when necessary in the course
of which it identifies and evaluates associated liabilities and costs
(including, without limitation, any



                                       33
<PAGE>   41

capital or operating expenditures required for clean-up or closure of properties
presently owned, any capital or operating expenditures required to achieve or
maintain compliance with environmental protection standards imposed by law or as
a condition of any license, permit or contract, any related constraints on
operating activities, and any actual or potential liabilities to third parties,
including employees, and any related costs and expenses). On the basis of this
review, the Borrower has reasonably concluded that no such associated
liabilities and costs, including the costs of compliance with Environmental
Laws, (i) are, as of the date hereof, Significant Environmental Costs, or (ii)
would have a Material Adverse Effect on the Borrower, Guarantor and their
Consolidated Subsidiaries.

               SECTION 4.8. Taxes. United States Federal income tax returns of
the Borrower, Guarantor and their Consolidated Subsidiaries have been prepared

Guarantor and their Consolidated Subsidiaries have filed all United States
Federal income tax returns and all other material tax returns which are required
to be filed by them and have paid all taxes due pursuant to such returns or
pursuant to any assessment received by the Borrower, Guarantor or any
Consolidated Subsidiary, except such taxes, if any, as are reserved against in
accordance with GAAP, such taxes as are being contested in good faith by
appropriate proceedings or such taxes, the failure to make payment of which when
due and payable will not have, in the aggregate, a Material Adverse Effect. The
charges, accruals and reserves on the books of the Borrower, Guarantor and their
Consolidated Subsidiaries in respect of taxes or other governmental charges are,
in the opinion of the Borrower, adequate.

               SECTION 4.9. Full Disclosure. All factual information heretofore
prepared by the Borrower and furnished by the Borrower to the Administrative
Agent or any Bank for purposes of or in connection with this Agreement or any
transaction contemplated hereby or thereby is true and accurate in all material
respects as of the date as of which such information is stated or certified.
There is no fact known to the Borrower (other than matters of a general economic
nature) that has had or could reasonably be expected to have a Material Adverse
Effect and that has not been disclosed herein or in such other documents,
certificates or statements executed or delivered in connection herewith.

               SECTION 4.10. Solvency. On the Closing Date and after giving
effect to the transactions contemplated by the Loan Documents occurring on the
Closing Date, the Borrower will be Solvent.

               SECTION 4.11. Use of Proceeds; Margin Regulations. All proceeds
of the Loans will be used by the Borrower only in accordance with the provisions
hereof. No part of the proceeds of any Loan will be used by the Borrower to
purchase or carry any Margin Stock or to extend credit to others for the purpose
of purchasing or carrying any Margin Stock. Neither the making of any Loan nor
the use of the proceeds thereof



                                       34
<PAGE>   42

will violate or be inconsistent with the provisions of Regulations G, T, U or X
of the Federal Reserve Board.

               SECTION 4.12. Governmental Approvals. No order, consent,
approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, any governmental or public body or
authority, or any subdivision thereof, is required to authorize, or is required
in connection with the execution, delivery and performance of any Loan Document
or the consummation of any of the transactions contemplated thereby other than
those that have already been duly made or obtained and remain in full force and
effect or those which, if not made or obtained, would not have a Material
Adverse Effect.

               SECTION 4.13. Investment Company Act; Public Utility Holding
Company Act. Neither the Borrower, Guarantor nor any Consolidated Subsidiary is
(x) an "investment company" or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended,

1997, Guarantor qualified and Guarantor shall continue to qualify as a real
estate investment trust under the Code.

               SECTION 4.16. Patents, Trademarks, etc. The Borrower has obtained
and holds in full force and effect all patents, trademarks, servicemarks, trade
names, copyrights and other such rights, free from burdensome restrictions,
which are necessary for the operation of its business as presently conducted,
the impairment of which is reasonably expected to have a Material Adverse
Effect.

               SECTION 4.17. Qualifying Unencumbered Properties. Schedule 4.17
attached hereto and made a part hereof sets forth all the Qualifying
Unencumbered Property owned by the Borrower, directly or indirectly, as of the

Borrower and the Borrower is not in default in any material respect beyond any
applicable grace period under or with respect to any other material agreement,
instrument or undertaking to which it is a party or by which it or any of its
property is bound in any respect in any such case, the existence of which
default is reasonably expected to result in a Material Adverse Effect.

               SECTION 4.19. Licenses, etc. The Borrower has obtained and does
hold in full force and effect, all franchises, licenses, permits, certificates,
authorizations, qualifications, accreditation, easements, rights of way and
other consents and approvals which are necessary for the operation of its
businesses as presently conducted, the absence of which is reasonably expected
to have a Material Adverse Effect.

               SECTION 4.20. Compliance With Law. The Borrower and each of the
Real Property Assets are in compliance with all laws, rules, regulations,
orders, judgments, writs and decrees, including, without limitation, all
building and zoning ordinances and codes, the failure to comply with which is
reasonably expected to have a Material Adverse Effect.

               SECTION 4.21. No Burdensome Restrictions. Except as may have been
disclosed by the Borrower in writing to the Banks, Borrower is not a party to
any agreement or instrument or subject to any other obligation or any charter or

               SECTION 4.22. Brokers' Fees. The Borrower has not dealt with any
broker or finder with respect to the transactions contemplated by this Agreement
or otherwise in connection with this Agreement, and the Borrower has not done

                                       36
<PAGE>   44

               SECTION 4.24. Insurance. The Borrower currently maintains 100%
replacement cost insurance coverage (subject to customary deductibles) in
respect of each of the Real Property Assets, as well as commercial general
liability insurance (including "builders' risk" where applicable) against claims
for personal, and bodily injury and/or death, to one or more persons, or
property damage, as well as workers' compensation insurance, in each case with
respect to liability and casualty insurance with insurers having an A.M. Best
policyholders, rating of not less than A-VII (or such lesser rating satisfactory
to Administrative Agent in its reasonable discretion) in amounts that prudent
owner of assets such as the Real Property Assets would maintain.

               SECTION 4.25. Organizational Documents. The documents delivered
pursuant to Section 3.1(e) constitute, as of the Closing Date, all of the
material organizational documents (together with all amendments and

copies of each of the documents set forth in Section 3.1(e).

               SECTION 4.26. Year 2000 Compliance. The Borrower and Guarantor
have each conducted a comprehensive review and assessment of the Borrower's and
Guarantor's computer applications and made inquiry of the Borrower's and
Guarantor's key suppliers, vendors and customers with respect to the "year 2000
problem" (that is the risk that computer applications may not be able to
properly perform date-sensitive functions after December 31, 1999) and, based on
that review and inquiry, neither the Borrower nor Guarantor believes the year
2000 problem will result in a material adverse change in the Borrower's or
Guarantor's ability to repay the Loans.

                                   ARTICLE V.

request of the Administrative Agent from time to time full information as to the
insurance carried, and (ii) forthwith, notice of any cancellation or nonrenewal

cause its Subsidiaries to comply in all material respects with all applicable

trademarks, servicemarks, tradenames, copyrights, franchises, licenses, permits,
certificates, authorizations, qualifications, accreditation, easements, rights
of way and other rights, consents and approvals the nonexistence of which is

               SECTION 5.10.  Restriction on Fundamental Changes.

               (a) Neither the Borrower, the Guarantor, nor any Consolidated

without the prior written consent of the Required Banks which consent may be
withheld in its sole and absolute discretion unless (i) the Borrower or the
Guarantor is the surviving entity, (ii) the entity which is merged into the

wind up or dissolve or sell, lease, transfer or otherwise dispose of, in one
transaction or a series of transactions, all or substantially all of its or

term equal to the term of such floating rate loan (to the extent the term of
such floating rate loan is less than two (2) years), (ii) shall have the effect
of capping the interest rates covered thereby at a rate equal to or lower than
the Cap Rate at the time of purchase or execution, and (iii) shall be with an
Approved Financial Institution as the counterparty. It is acknowledged and
agreed that the Borrower shall have no obligation to replace any Interest Rate
Hedge even if the counterparty thereto shall cease to be an Approved Financial
Institution. The Borrower shall certify its compliance with Interest Rate Hedges
to the Administrative Agent in the certificate required to be delivered by the
Borrower pursuant to Section 5.1(c), which certificate shall be in the form of

        being owned by Guarantor.

               SECTION 5.15.  Environmental Matters.

               (a) Promptly upon the discovery of any Environmental Claim or of
any violation or alleged violation of Environmental Laws with respect to any
Qualifying Unencumbered Asset, the Borrower shall attempt in good faith, as soon
as practicable, to determine all costs it reasonably expects any party to expend
in connection with the investigation and resolution of such Environmental Claim
or of such violation or alleged violation of Environmental Laws. The Borrower
shall thereupon notify the Administrative Agent in writing of the Borrower's
reasonable, good faith estimate of the cost to investigate and resolve such
Environmental Claim or such violation or alleged violation if such cost is equal
to or greater than $250,000. Such good faith estimate of such costs, as revised
from time to time pursuant hereto, shall be deemed to be the "Estimated
Environmental Cost" of such Environmental Claim or such violation or alleged
violation of Environmental Laws. After the end of each Fiscal Quarter, the
Borrower shall review and update all Estimated Environmental Costs and shall
deliver, with the Borrower's quarterly reports delivered in accordance with
Section 5.1 hereof, a written report to the Administrative Agent, setting forth,
in reasonable detail, each Estimated Environmental Cost which is in excess of
$250,000, the basis for the determination of such Estimated Environmental Cost,
and the Borrower's plans with respect to such Environmental Claim or such
violation or alleged violation of Environmental Laws. If the Borrower at any
time is not diligently and in good faith pursuing a determination of or an
update of a Estimated Environmental Cost which exceeds $250,000, the
Administrative Agent may, in reliance upon the opinions and judgments of
environmental consultants (either independent or employed by the Administrative
Agent), estimate or update, in good faith, the cost to investigate and resolve
an Environmental Claim or alleged or actual violation of Environmental Laws. In
the event that the Administrative Agent makes any such determination, the
Estimated Environmental Cost of investigating and resolving such Environmental
Claim or such alleged or actual violation of Environmental Laws shall be the
Administrative Agent's



                                       45
<PAGE>   53

estimate, until such time as Borrower again diligently pursues in good faith the
determination or update of Estimated Environmental Cost, and upon Borrower's
determination of a Estimated Environmental Cost in compliance herewith the
Estimated Environmental Cost shall thereafter be Borrower's estimate thereof, as
set forth herein.

               (b) The Borrower shall, at all times, diligently and in good
faith pursue resolution of all Environmental Claims, and all violations or
alleged violations of Environmental Laws, with respect to its Properties.

               SECTION 5.16. Cooperation. The Borrower shall take any action
reasonably requested by the Administrative Agent to carry out the intent of the
Loan Documents.

               SECTION 5.17. Distributions. Unless waived by the Required Banks,
no Borrower Party shall make any Restricted Payments after the occurrence of and
during the continuation of an Event of Default under Section 6.1(a); provided
however that Borrower may make Restricted Payments to partners in Borrower to
the extent necessary to enable Guarantor to make dividend payments to its
stockholders as required for Guarantor to maintain its status as a real estate
investment trust under the Code. In such case, Borrower shall cause Guarantor to
make such dividend payments.

                                   ARTICLE VI.

after written notice thereof has been given to the Borrower by the

reasonable effort be completely remedied within said period of thirty (30) days

default, event or condition is to accelerate the maturity of any such
indebtedness or to permit (without any further requirement of notice or lapse of

to accelerate the maturity of any such indebtedness;

aggregate amount of Ten Million Dollars ($10,000,000) or more shall be entered

further amended by that certain Second Amendment To Revolving Credit Agreement
dated as of August 4, 1998, as it may be amended hereafter from time to time.

               SECTION 6.2.  Rights and Remedies.

               (a) Upon the occurrence of any Event of Default described in
Sections 6.1(f) or (g), the Commitment shall immediately terminate and the
unpaid principal amount of, and any and all accrued interest on, the Loans and
any and all accrued fees and other Obligations hereunder shall automatically
become immediately due and payable, with all additional interest from time to
time accrued thereon and without presentation, demand, or protest or other
requirements of any kind (including, without limitation, valuation and
appraisement, diligence, presentment, notice of intent to demand or accelerate
and notice of acceleration), all of which are hereby expressly waived by the
Borrower; and upon the occurrence and during the continuance of any other Event
of Default, the Administrative Agent upon the demand of the Required Banks
shall, by written notice to the Borrower, in addition to the exercise of all of
the rights and remedies permitted the Administrative Agent and the Banks at law
or equity or under any of the other Loan Documents, declare the unpaid principal
amount of and any and all accrued and unpaid interest on the Loans and any and
all accrued fees and other obligations hereunder to be, and the same shall
thereupon be, immediately due and payable with all additional interest from time
to time accrued thereon and (except as otherwise as provided in the Loan
Documents) without presentation, demand, or protest or other requirements of any
kind (including, without limitation, valuation and appraisement, diligence,
presentment, notice of intent to demand or accelerate and notice of
acceleration), all of which are hereby expressly waived by the Borrower.

               (b) Notwithstanding anything to the contrary contained in this
Agreement or in any other Loan Document, the Administrative Agent, and the Banks
each agree that any exercise or enforcement of the rights and remedies granted
to the Administrative Agent or the Banks under this Agreement or at law or in
equity with respect to this Agreement or any other Loan Documents shall be
commenced and maintained by the Administrative Agent on behalf of the
Administrative Agent and/or the Banks. The Administrative Agent shall act at the
direction of the Required Banks in



                                       49
<PAGE>   57

connection with the exercise of any and all remedies at law, in equity or under
any of the Loan Documents or, if the Required Banks are unable to reach
agreement on the exercise of remedies, then, from and after Administrative Agent
shall have declared the Loan immediately due and payable, the Administrative
Agent may pursue such rights and remedies as it may determine.

               SECTION 6.3. Notice of Default. The Administrative Agent shall
give notice to the Borrower under Section 6.1(c) promptly upon being requested
to do so by the Required Banks and shall thereupon notify all the Banks thereof.
The Administrative Agent shall not be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default (other than nonpayment of
principal of or interest on the Loans) unless the Administrative Agent has
received notice in writing from a Bank or Borrower referring to this Agreement
or the other Loan Documents, describing such event or condition. Should
Administrative Agent receive notice of the occurrence of a Default or Event of
Default expressly stating that such notice is a notice of a Default or Event of
Default, or should Administrative Agent send Borrower a notice of Default or
Event of Default, Administrative Agent, shall promptly give notice thereof to
each Bank.

               SECTION 6.4. Distribution of Proceeds after Default. Subject to
Section 7.6, from and after an Event of Default, to the extent proceeds are
received by Administrative Agent, such proceeds will be distributed to the Banks
pro rata in accordance with the unpaid principal amount of the Loans. Regardless
of how each Bank may treat payments received by it pursuant to this Agreement
and the Notes delivered to evidence debt hereunder for the purpose of its own
accounting, for the purpose of computing the Borrower's and Guarantor's
obligations under this Agreement and under such Notes, the payments shall be
applied first, to the costs and expenses (including attorneys' fees and
disbursements and the allocated costs and expenses of in-house legal and other
professional services) of the Administrative Agent, acting as Administrative
Agent, and of the Banks as set forth herein, second, to the payment of accrued
and unpaid interest on all Notes to and including the date of such application
(ratably according to the accrued and unpaid interest on the Notes), third, to
the ratable payment of the unpaid principal of all the Notes, and fourth, to the
payment of all other amounts (including fees) then owing to the Administrative
Agents or the Banks under the Loan Documents. No application of the payments
will cure any Event of Default or prevent acceleration, or continued
acceleration, of amounts payable under the Loan Documents or prevent the
exercise, or continued exercise, of rights or remedies of the Banks under this
Agreement or under law.

                                  ARTICLE VII.

                                   THE AGENTS

               SECTION 7.1. Appointment and Authorization. Each Bank irrevocably
appoints and authorizes the Administrative Agent to take such action as agent on
its behalf and to exercise such powers under this Agreement and the other Loan
Documents



                                       50
<PAGE>   58

as are delegated to the Administrative Agent by the terms hereof or thereof,
together with all such powers as are reasonably incidental thereto. Except as
set forth in Sections 7.8 and 7.9 hereof, the provisions of this Article VII are
solely for the benefit of Administrative Agent and the Banks, and Borrower shall
not have any rights to rely on or enforce any of the provisions hereof. In
performing its functions and duties under this Agreement, the Administrative
Agent shall act solely as an agent of the Banks and shall not assume and shall
not be deemed to have assumed any obligation toward or relationship of agency or
trust with or for the Borrower.

               SECTION 7.2. Agency and Affiliates. Wells Fargo shall have the
same rights and powers under this Agreement as any other Bank and may exercise
or refrain from exercising the same as though it were not the Administrative
Agent. Wells Fargo (and its affiliates) may accept deposits from, lend money to,
and generally engage in any kind of business with the Borrower, Guarantor or any
Subsidiary or affiliate of the Borrower as if it were not the Administrative
Agent hereunder, and the term "Bank" and "Banks" shall include Wells Fargo in
its individual capacity.

               SECTION 7.3. Action by Administrative Agent. The obligations of
the Administrative Agent hereunder are only those expressly set forth herein.
Without limiting the generality of the foregoing, the Administrative Agent shall
not be required to take any action with respect to any Default or Event of
Default, except as expressly provided in Article VI. The duties of
Administrative Agent shall be administrative in nature. Subject to the
provisions of Sections 7.1, 7.5 and 7.6, Administrative Agent shall administer
the Loans in the same manner as it administers its own loans.

               SECTION 7.4. Consultation with Experts. As between Administrative
Agent and the Banks, the Administrative Agent may consult with legal counsel
(who may be counsel for the Borrower), independent public accountants and other
experts selected by it and shall not be liable for any action taken or omitted
to be taken by it in good faith in accordance with the advice of such counsel,
accountants or experts.

               SECTION 7.5 Liability of Administrative Agent. As between
Administrative Agent and the Banks, none of the Administrative Agent nor any of
its affiliates nor any of their respective directors, officers, agents or
employees shall be liable for any action taken or not taken by it in connection
herewith (i) with the consent or at the request of the Required Banks or (ii) in
the absence of its own gross negligence or willful misconduct. As between
Administrative Agent and the Banks, none of the Administrative Agent nor any of
its directors, officers, agents or employees shall be responsible for or have
any duty to ascertain, inquire into or verify (i) any statement, warranty or
representation made in connection with this Agreement or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or
agreements of the Borrower; (iii) the satisfaction of any condition specified in
Article III, except receipt of items required to be delivered to the
Administrative Agent; or (iv) the validity, effectiveness or genuineness of this
Agreement, the other Loan Documents or any other instrument or writing furnished
in connection herewith. As between Administrative



                                       51
<PAGE>   59

Agent and the Banks, the Administrative Agent shall not incur any liability by
acting in reliance upon any notice, consent, certificate, statement, or other
writing (which may be a bank wire, telex or similar writing) believed by it to
be genuine or to be signed by the proper party or parties.

               SECTION 7.6. Indemnification. Each Bank shall, ratably in
accordance with its Commitment, indemnify the Administrative Agent and its
affiliates and its respective directors, officers, agents and employees (to the
extent not reimbursed by the Borrower) against any cost, expense (including
counsel fees and disbursements), claim, demand, action, loss or liability
(except such as result from such indemnitee's gross negligence or willful
misconduct) that such indemnitee may suffer or incur in connection with its
duties as Administrative Agent under this Agreement, the other Loan Documents or
any action taken or omitted by such indemnitee hereunder. In the event that the
Administrative Agent shall, subsequent to its receipt of indemnification
payment(s) from Banks in accordance with this Section, recoup any amount from
the Borrower, or any other party liable therefor in connection with such
indemnification, the Administrative Agent shall reimburse the Banks which
previously made the payment(s) pro rata, based upon the actual amounts which
were theretofore paid by each Bank. The Administrative Agent shall reimburse
such Banks so entitled to reimbursement within two (2) Domestic Business Days of
its receipt of such funds from the Borrower or such other party liable therefor.

               SECTION 7.7. Credit Decision. Each Bank acknowledges that it has,
independently and without reliance upon the Administrative Agent or any other
Bank, and based on such documents and information as it has deemed appropriate,
made its own credit analysis and decision to enter into this Agreement. Each
Bank also acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Bank, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking any action under this Agreement.

               SECTION 7.8. Successor Administrative Agent. The Administrative
Agent may resign at any time by giving notice thereof to the Banks and the
Borrower and the Administrative Agent shall resign in the event its Commitment
is reduced to below five percent (5%) of the Aggregate Commitments. Upon any
such resignation, the Required Banks shall have the right to appoint a successor
Administrative Agent, which successor Administrative Agent shall, provided no
Event of Default has occurred and is then continuing, be subject to Borrower's
approval, which approval shall not be unreasonably withheld or delayed. If no
successor Administrative Agent shall have been so appointed by the Required
Banks and approved by the Borrower, and shall have accepted such appointment,
within 30 days after the retiring Administrative Agent gives notice of
resignation, then the retiring Administrative Agent may, on behalf of the Banks,
appoint a successor Administrative Agent, who shall act until the Required Banks
shall appoint a Administrative Agent. Upon the acceptance of its appointment as
the Administrative Agent hereunder by a successor Administrative Agent, such
successor



                                       52
<PAGE>   60

Administrative Agent shall thereupon succeed to and become vested with all the
rights and duties of the retiring Administrative Agent, and the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder. After any retiring Administrative Agent's resignation hereunder, the
provisions of this Article shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was the Administrative Agent. For gross
negligence or willful misconduct, as determined by the Required Banks (excluding
for such determination Administrative Agent in its capacity as a Bank, but in no
event shall such determination be made by less than two (2) Banks),
Administrative Agent may be removed at any time by giving at least thirty (30)
Domestic Business Days prior written notice to Administrative Agent and
Borrower. Such resignation or removal shall take effect upon the acceptance of
appointment by a successor Administrative Agent, in accordance with the
provisions of this Section 7.8.

               SECTION 7.9. Consents and Approvals. All communications from
Administrative Agent to the Banks requesting the Banks' determination, consent,
approval or disapproval (i) shall be given in the form of a written notice to
each Bank (ii) shall be accompanied by a description of the matter or item as to
which such determination, approval, consent or disapproval is requested, or
shall advise each Bank where such matter or item may be inspected, or shall
otherwise describe the matter or issue to be resolved, (iii) shall include, if
reasonably requested by a Bank and to the extent not previously provided to such
Bank, written materials and a summary of all oral information provided to
Administrative Agent by Borrower in respect of the matter or issue to be
resolved, and (iv) shall include Administrative Agent's recommended course of
action or determination in respect thereof. Each Bank shall reply promptly, but
in any event within ten (10) Domestic Business Days after receipt of the request
therefor from Administrative Agent (the "Bank Reply Period"). Unless a Bank
shall give written notice to Administrative Agent that it objects to the
recommendation or determination of Administrative Agent (together with a written
explanation of the reasons behind such objection) within the Bank Reply Period,
such Bank shall be deemed to have approved of or consented to such
recommendation or determination. With respect to decisions requiring the
approval of the Required Banks or all the Banks, Administrative Agent shall
submit its recommendation or determination for approval of or consent to such
recommendation or determination to all Banks and upon receiving the required
approval or consent shall follow the course of action or determination of the
Required Banks (and each non-responding Bank shall be deemed to have concurred
with such recommended course of action) or all the Banks, as the case may be.

                                  ARTICLE VIII.

                             CHANGE IN CIRCUMSTANCES

               SECTION 8.1. Basis for Determining Interest Rate Inadequate or
Unfair. If on or prior to the first day of any Interest Period for any LIBOR
Borrowing or any continuation of the LIBOR Loans (or portions thereof)
comprising such Borrowing:



                                       53
<PAGE>   61

               (a) the Administrative Agent has determined in good faith that
deposits in dollars (in the applicable amounts) are not being offered in the
relevant market for such Interest Period, or

               (b) Banks having 50% or more of the Aggregate Commitments advise
the Administrative Agent that the Adjusted London Interbank Offered Rate, as
determined by the Administrative Agent, will not adequately and fairly reflect
the cost to such Bank of continuing its Loans as LIBOR Loans for such Interest
Period,

               the Administrative Agent shall forthwith give notice thereof to
the Borrower and the Banks, whereupon until the Administrative Agent notifies
the Borrower that the circumstances giving rise to such suspension no longer
exist, the obligations of the Banks to continue their Loans as LIBOR Loans for
such Interest Period shall be suspended. With respect to any Borrowing to be
made upon the commencement of an extension term, unless the Borrower notifies
the Administrative Agent at least two Domestic Business Days before the date of
such Borrowing that it elects not to exercise the First Option To Extend or the
Second Option To Extend, as applicable, the Borrowing shall instead be made as a
Base Rate Borrowing and the Loans comprising such Borrowing shall bear interest
for each day from and including the first day to but excluding the last day of
the Interest Period applicable thereto at the Base Rate for such day. For
purposes of this Section 8.1(b), in determining whether the Adjusted London
Interbank Offered Rate, as determined by Administrative Agent, will not
adequately and fairly reflect the cost to any Bank of continuing its Loans as
LIBOR Loans for such Interest Period, such determination will be based solely on
the ability of such Bank to obtain matching funds in the London interbank market
at a reasonably equivalent rate.

               SECTION 8.2. Illegality. If, on or after the date of this
Agreement, the adoption of any applicable law, rule or regulation, or any change
in any applicable law, rule or regulation, or any change in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its LIBOR Lending Office) with any request or
directive (whether or not having the force of law) made after the Closing Date
of any such authority, central bank or comparable agency shall make it unlawful
for any Bank (or its LIBOR Lending Office) to make, maintain or fund its LIBOR
Loans, the Administrative Agent shall forthwith give notice thereof to the other
Banks and the Borrower, whereupon until such Bank notifies the Borrower and the
Administrative Agent that the circumstances giving rise to such suspension no
longer exist, the obligation of such Bank, if any, to continue its Loan as a
LIBOR Loan for any subsequent Interest Period shall be suspended and, to the
extent such Bank has an obligation to continue its Loan after the expiration of
the then current Interest Period, such Loan shall be continued as a Base Rate
Loan as set forth below. With respect to any such LIBOR Loan, before giving any
notice to the Administrative Agent pursuant to this Section, such Bank shall
designate a different LIBOR Lending Office if such designation will avoid the
need for giving such notice and will not, in the judgment of such Bank, be
otherwise disadvantageous to such Bank. Notwithstanding anything in the
foregoing to



                                       54
<PAGE>   62

the contrary, if such Bank shall determine that it may not lawfully continue to
maintain any of its outstanding LIBOR Loans to maturity and shall so specify in
such notice, such LIBOR Loan shall be converted as of such date to a Base Rate
Loan (without payment of any amounts that Borrower would otherwise be obligated
to pay pursuant to Section 2.11 hereof with respect to Loans converted pursuant
to this Section 8.2) in an equal principal amount from such Bank (on which
interest and principal shall be payable contemporaneously with the related LIBOR
Loans of the other Banks), and such Bank shall make such a Base Rate Loan.

               If at any time, it shall be unlawful for any Bank to make,
maintain or continue its LIBOR Loan, the Borrower shall have the right, upon
five (5) Domestic Business Day's notice to the Administrative Agent, to either
(x) cause a bank, reasonably acceptable to the Administrative Agent, to offer to
purchase the Commitments of such Bank for an amount equal to such Bank's
outstanding Loan, and to become a Bank hereunder, or obtain the agreement of one
or more existing Banks to offer to purchase the Commitments of such Bank for
such amount, which offer such Bank is hereby required to accept, or (y) to repay
in full all Loans then outstanding of such Bank, together with interest and all
other amounts due thereon, upon which event, the Aggregate Commitments shall be
reduced by the amount of such Bank's Commitment and such Bank shall cease to be
a Bank hereunder.

               SECTION 8.3.  Increased Cost and Reduced Return.

               (a) If, on or after the date hereof, the adoption of any
applicable law, rule or regulation, or any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its
Applicable Lending Office) with any request or directive (whether or not having
the force of law) made at the Closing Date of any such authority, central bank
or comparable agency shall impose, modify or deem applicable any reserve
(including, without limitation, any such requirement imposed by the Board of
Governors of the Federal Reserve System (but excluding with respect to any LIBOR
Loan any such requirement reflected in an applicable LIBOR Reserve Percentage)),
special deposit, insurance assessment or similar requirement against assets of,
deposits with or for the account of, or credit extended by, any Bank (or its
Applicable Lending Office) or shall impose on any Bank (or its Applicable
Lending Office) or on the London interbank market any other condition materially
more burdensome in nature, extent or consequence than those in existence as of
the Closing Date affecting such Bank's LIBOR Loan, its Note, or its obligation
to make LIBOR Loans, and the result of any of the foregoing is to increase the
cost to such Bank (or its Applicable Lending Office) of making or maintaining
any LIBOR Loan, or to reduce the amount of any sum received or receivable by
such Bank (or its Applicable Lending Office) under this Agreement or under its
Note with respect to such LIBOR Loan, by an amount deemed by such Bank to be
material, then, within fifteen (15) days after demand by such Bank (with a copy
to the Administrative Agent), the Borrower shall pay to such Bank such
additional amount or



                                       55
<PAGE>   63

amounts (based upon a reasonable allocation thereof by such Bank to the LIBOR
Loan made by such Bank hereunder) as will compensate such Bank for such
increased cost or reduction to the extent such Bank generally imposes such
additional amounts on other borrowers of such Bank in similar circumstances.

               (b) If any Bank shall have reasonably determined that, after the
date hereof, the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change in any such law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) made after the Closing Date of any such
authority, central bank or comparable agency, has or would have the effect of
reducing the rate of return on capital of such Bank (or its Parent) as a
consequence of such Bank's obligations hereunder to a level below that which
such Bank (or its Parent) could have achieved but for such adoption, change,
request or directive (taking into consideration its policies with respect to
capital adequacy) by an amount reasonably deemed by such Bank to be material,
then from time to time, within fifteen (15) days after demand by such Bank (with
a copy to the Administrative Agent), the Borrower shall pay to such Bank such
additional amount or amounts as will compensate such Bank (or its Parent) for
such reduction to the extent such Bank generally imposes such additional amounts
on other borrowers of such Bank in similar circumstances.

               (c) Each Bank will promptly notify the Borrower and the
Administrative Agent of any event of which it has knowledge, occurring after the
date hereof, which will entitle such Bank to compensation pursuant to this
Section and will designate a different Applicable Lending office if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the reasonable judgment of such Bank, be otherwise
disadvantageous to such Bank. If such Bank shall fail to notify Borrower of any
such event within ninety (90) days following the end of the month during which
such event occurred, then Borrower's liability for any amounts described in this
Section incurred by such Bank as a result of such event shall be limited to
those attributable to the period occurring subsequent to the ninetieth (90th)
day prior to the date upon which such Bank actually notified Borrower of the
occurrence of such event. A certificate of any Bank claiming compensation under
this Section and setting forth a reasonably detailed calculation of the
additional amount or amounts to be paid to it hereunder shall be conclusive in
the absence of demonstrable error. In determining such amount, such Bank may use
any reasonable averaging and attribution methods.

               (d) If at any time, any Bank shall be owed amounts pursuant to
this Section 8.3, the Borrower shall have the right, upon five (5) Domestic
Business Day's notice to the Administrative Agent to either (x) cause a bank,
reasonably acceptable to the Administrative Agent, to offer to purchase the
Commitment of such Bank for an amount equal to such Bank's outstanding Loan, and
to become a Bank hereunder, or to obtain the agreement of one or more existing
Banks to offer to purchase the Commitment of such Bank for such amount, which
offer such Bank is hereby required to accept, or (y) to repay



                                       56
<PAGE>   64

in full all Loans then outstanding of such Bank, together with interest and all
other amounts due thereon, upon which event, the Aggregate Commitments shall be
reduced by the amount of such Bank's Commitment and such Bank shall cease to be
a Bank hereunder.

               SECTION 8.4.  Taxes.

               (a) Any and all payments by the Borrower to or for the account of
any Bank or the Administrative Agent hereunder or under any other Loan Document
shall be made free and clear of and without deduction for any and all present or
future taxes, duties, levies, imposts, deductions, charges or withholdings, and
all liabilities with respect thereto, excluding, in the case of each Bank and
the Administrative Agent, taxes imposed on its income, and franchise taxes
imposed on it, by the jurisdiction under the laws of which such Bank or the
Administrative Agent (as the case may be) is organized or any political
subdivision thereof and, in the case of each Bank, taxes imposed on its income,
and franchise or similar taxes imposed on it, by the jurisdiction of such Bank's
Applicable Lending Office or any political subdivision thereof or by any other
jurisdiction (or any political subdivision thereof) as a result of a present or
former connection between such Bank or Administrative Agent and such other
jurisdiction or by the United States (all such non-excluded taxes, duties,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Non-Excluded Taxes"). If the Borrower shall be
required by law to deduct any Non-Excluded Taxes from or in respect of any sum
payable hereunder or under any Note, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 8.4) such Bank or the
Administrative Agent (as the case may be) receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower shall
make such deductions, (iii) the Borrower shall pay the full amount deducted to
the relevant taxation authority or other authority in accordance with applicable
law and (iv) the Borrower shall furnish to the Administrative Agent, at its
address referred to in Section 9.1, the original or a certified copy of a
receipt evidencing payment thereof.

               (b) In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes and any other excise or property taxes, or charges or
similar levies which arise from any payment made hereunder or under any Note or
from the execution or delivery of, or otherwise with respect to, this Agreement
or any Note (hereinafter referred to as "Other Taxes").

               (c) The Borrower agrees to indemnify each Bank and the
Administrative Agent for the full amount of Non-Excluded Taxes or Other Taxes
(including, without limitation, any Non-Excluded Taxes or Other Taxes imposed or
asserted by any jurisdiction on amounts payable under this Section 8.4) paid by
such Bank or the Administrative Agent (as the case may be) and, so long as such
Bank or Administrative Agent has promptly paid any such Non-Excluded Taxes or
Other Taxes, any liability for penalties and interest arising therefrom or with
respect thereto. This



                                       57
<PAGE>   65

indemnification shall be made within fifteen (15) days from the date such Bank
or the Administrative Agent (as the case may be) makes demand therefor.

               (d) Each Bank organized under the laws of a jurisdiction outside
the United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on
or prior to the date on which it becomes a Bank in the case of each other Bank,
shall provide the Borrower with (a) two duly completed copies of Internal
Revenue Service form 1001 or 4224, as appropriate, or any successor form
prescribed by the Internal Revenue Service, and (b) an Internal Revenue Service
Form W-8 or W-9, or any successor form prescribed by the Internal Revenue
Service, and shall provide Borrower with two further copies of any such form or
certification on or before the date that any such form or certification expires
or becomes obsolete and after the occurrence of any event requiring a change in
the most recent form previously delivered by it to Borrower, certifying (i) in
the case of a Form 1001 or 4224, that such Bank is entitled to benefits under an
income tax treaty to which the United States is a party which reduces the rate
of withholding tax on payments of interest or certifying that the income
receivable pursuant to this Agreement is effectively connected with the conduct
of a trade or business in the United States, and (ii) in the case of a Form W-8
or W-9, that it is entitled to an exemption from United States backup
withholding tax. If the form provided by a Bank at the time such Bank first
becomes a party to this Agreement indicates a United States interest withholding
tax rate in excess of zero, withholding tax at such rate shall be considered
excluded from "Non-Excluded Taxes" as defined in Section 8.4(a).

               (e) For any period with respect to which a Bank has failed to
provide the Borrower with the appropriate form pursuant to Section 8.4(d)
(unless such failure is due to a change in treaty, law or regulation occurring
subsequent to the date on which a form originally was required to be provided),
such Bank shall not be entitled to indemnification under Section 8.4(c) with
respect to Non-Excluded Taxes imposed by the United States, provided, however,
that should a Bank, which is otherwise exempt from or subject to a reduced rate
of withholding tax, become subject to Non-Excluded Taxes because of its failure
to deliver a form required hereunder, the Borrower shall take such steps as such
Bank shall reasonably request to assist such Bank to recover such Taxes so long
as Borrower shall incur no cost or liability as a result thereof.

               (f) If the Borrower is required to pay additional amounts to or
for the account of any Bank pursuant to this Section 8.4, then such Bank will
change the jurisdiction of its Applicable Lending Office so as to eliminate or
reduce any such additional payment which may thereafter accrue if such change,
in the judgment of such Bank, is not otherwise disadvantageous to such Bank.

               (g) If at any time, any Bank shall be owed amounts pursuant to
this Section 8.4, the Borrower shall have the right, upon five (5) Domestic
Business Day's notice to the Administrative Agent to either (x) cause a bank,
reasonably acceptable to the Administrative Agent, to offer to purchase the
Commitment of such Bank for an amount



                                       58
<PAGE>   66

equal to such Bank's outstanding Loan, and to become a Bank hereunder, or to
obtain the agreement of one or more existing Banks to offer to purchase the
Commitment of such Bank for such amount, which offer such Bank is hereby
required to accept, or (y) to repay in full all Loans then outstanding of such
Bank, together with interest and all other amounts due thereon, upon which
event, the Aggregate Commitments shall be reduced by the amount of such Bank's
Commitment and such Bank shall cease to be a Bank hereunder.

               SECTION 8.5. Base Rate Loans Substituted for Affected LIBOR
Loans. If (i) the obligation of any Bank to continue its Loan as a LIBOR Loan
has been suspended pursuant to Sections 8.1 or 8.2 or (ii) any Bank has demanded
compensation under Section 8.3 or 8.4 with respect to its LIBOR Loan and the
Borrower shall, by at least five LIBOR Business Days' prior notice to such Bank
through the Administrative Agent, have elected that the provisions of this
Section 8.5 shall apply to such Bank, then, unless and until such Bank notifies
the Borrower that the circumstances giving rise to such suspension or demand for
compensation no longer exist:

               (a) any Loan which would otherwise be continued by such Bank as a
LIBOR Loan shall be continued instead as a Base Rate Loan (on which interest and
principal shall be payable contemporaneously with the related LIBOR Loans of the
other Banks), and

               (b) all payments of principal which would otherwise be applied to
repay such LIBOR Loan shall be applied to repay its Base Rate Loan instead, and

               (c) Borrower will not be required to make any payment which would
otherwise be required by Section 2.11 with respect to such LIBOR Loan converted
to a Base Rate Loan pursuant to clause (a) above.

                                   ARTICLE IX.

                                  MISCELLANEOUS

               SECTION 9.1. Notices. All notices, requests and other
communications to any party hereunder shall be in writing (including bank wire,
telex, facsimile transmission followed by telephonic confirmation or similar
writing) and shall be given to such party: (x) in the case of the Borrower or
the Administrative Agent, at its address, telex number or facsimile number set
forth on the signature pages hereof with a duplicate copy thereof, in the case
of the Borrower, to the Borrower, at Irvine Apartment Communities, L.P. c/o

if given by any other means, when delivered at the address specified in this

Article VIII shall not be effective until received.

               SECTION 9.2. No Waivers. No failure or delay by the
Administrative Agent or any Bank in exercising any right, power or privilege
hereunder or under any Note shall operate as a waiver thereof nor shall any
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The rights and
remedies herein provided shall be cumulative and not exclusive of any rights or
remedies provided by law.

               SECTION 9.3.  Expenses; Indemnification.

               (a) The Borrower shall pay within thirty (30) days after written
notice from the Administrative Agent all reasonable out-of-pocket costs and
expenses of the Administrative Agent (including the fees and disbursements of
outside counsel as well as the allocated cost of Administrative Agent's internal
legal services), in connection with the preparation of this Agreement, the Loan
Documents and the documents and instruments referred to therein, and any waiver,
consent hereunder and any amendment hereof, the administration hereof and any
Default or alleged Default hereunder, (ii) in connection with the syndication of
the Loans and (iii) if an Event of Default occurs, all reasonable out-of-pocket
expenses incurred by the Administrative Agent and the Banks as a group,
including fees and disbursements of counsel for the Administrative Agent and
each of the Banks, in connection with the enforcement of the Loan Documents and
the instruments referred to therein and such Event of Default and collection,
bankruptcy, insolvency and other enforcement proceedings resulting therefrom;
provided, however, that the attorneys' fees and disbursements for which Borrower
is obligated under this subsection (a)(iii) shall be limited to the reasonable
non-duplicative fees and disbursements of (a) counsel for Administrative Agent
and (b) counsel for all of the Banks as a group. For purposes of this Section
9.3(a)(iii), (1) counsel for Administrative Agent shall mean a single outside
law firm representing Administrative Agent together with the allocated cost of
Administrative Agent's internal legal services, and (2) counsel for all of the
Banks as a group shall mean a single outside law firm representing such Banks as
a group (which law firm may or may not be the same law firm representing
Administrative Agent).

<PAGE>   68

               (b) The Borrower agrees to indemnify the Administrative Agent,
each Bank and their respective affiliates and the respective directors,
officers, agents and employees of the foregoing (each an "Indemnitee") and hold
each Indemnitee harmless from and against any and all liabilities, losses,
damages, costs and expenses of any kind, including, without limitation, the
reasonable fees and disbursements of counsel, which may be incurred by such
Indemnitee in connection with any investigative, administrative or judicial
proceeding that may at any time (including, without limitation, at any time
following the payment of the Obligations) be asserted against any Indemnitee, as
a result of, or arising out of, or related to or by reason of, (i) any of the
transactions contemplated by the Loan Documents or the execution, delivery or
performance of any Loan Document, (ii) any violation by the Borrower or the
Environmental Affiliates of any applicable Environmental Law, (iii) any
Environmental Claim arising out of the management, use, control, ownership or
operation of property or assets by the Borrower or any of the Environmental
Affiliates, including, without limitation, all on-site and off-site activities
of Borrower or any Environmental Affiliate involving Materials of Environmental
Concern, (iv) the breach of any environmental representation or warranty set
forth herein, but in all cases excluding those liabilities, losses, damages,
costs and expenses (a) for which such Indemnitee has been compensated pursuant
to the terms of this Agreement, (b) incurred solely by reason of the gross
negligence, willful misconduct, bad faith or fraud of any Indemnitee as finally
determined by a court of competent jurisdiction, (c) violations of Environmental
Laws relating to a Property which are caused by the act or omission of such
Indemnitee after such Indemnitee takes possession or control (but in no event
shall appointment of a receiver or a trustee be deemed control) of such Property
or (d) any liability of such Indemnitee to any third party based upon
Contractual Obligations of such Indemnitee owing to such third party which are
not expressly set forth in the Loan Documents. In addition, the indemnification
set forth in this Section 9.3(b) in favor of any director, officer, agent or
employee of Administrative Agent or any Bank shall be solely in their respective
capacities as such director, officer, agent or employee. The Borrower's
obligations under this Section shall survive the termination of this Agreement
and the payment of the Obligations.

               (c) Each Indemnitee will promptly notify the Borrower of each
event of which it has knowledge that may give rise to a claim under clause (b)
of Section 9.3, provided that the failure to so notify the Borrower shall in no
way impair the Borrower's obligations under this Section 9.3 (except to the
extent that such failure to so notify arises from the gross negligence or
willful misconduct of such Indemnitee and has an adverse effect on the
Borrower). If any investigative, judicial or administrative proceeding is
brought against any Indemnitee indemnified or intended to be indemnified
pursuant to this Section 9.3, the Borrower, to the extent and in the manner
directed by the Indemnitee, will resist and defend such proceeding with counsel
designated by the Borrower (which counsel shall be reasonably satisfactory to
the Indemnitee). Each Indemnitee will use its best efforts to cooperate in the
defense of any such action, writ, or proceeding. The Borrower shall keep such
Indemnitee advised of the status of such defense and consult with such
Indemnitee prior to taking any material position with respect thereto. Such
Indemnitee shall, however, be entitled to employ counsel separate



                                       61
<PAGE>   69

from counsel for the Borrower and from any other party in such proceeding if
such Indemnitee shall reasonably determine that a conflict of interest or other
circumstance exists that makes representation by counsel chosen by the Borrower
not advisable. The fees and disbursements of such separate counsel shall be paid
by the Borrower. Such Indemnitee shall not agree to the settlement of any such
claim without the consent of the Borrower, unless the Borrower shall have been
given notice of the commencement of an action and shall have failed to provide
the defense thereof as herein provided or an Event of Default shall have
occurred.

               SECTION 9.4. Sharing of Set-Offs. In addition to any rights now
or hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, and after acceleration of the Obligations, each
Bank is hereby authorized at any time or from time to time, without presentment,
demand, protest or other notice of any kind to the Borrower or to any other
Person, any such notice being hereby expressly waived, but subject to the prior
consent of the Administrative Agent, to set off and to appropriate and apply any
and all deposits (general or special, time or demand, provisional or final) and
any other indebtedness at any time held or owing by such Bank (including,
without limitation, by branches and agencies of such Bank wherever located) to
or for the credit or the account of the Borrower against and on account of the
Obligations of the Borrower then due and payable to such Bank under this
Agreement or under any of the other Loan Documents, including, without
limitation, all interests in Obligations purchased by such Bank. Each Bank shall
notify the Borrower in writing promptly after any such set-off and the
application thereof made by such Bank; provided however that the failure to give
such notice shall not affect the validity of such set-off and application. Each
Bank agrees that if it shall by exercising any right of set-off or counterclaim
or otherwise, receive payment of a proportion of the aggregate amount of
principal and interest due with respect to any Note held by it which is greater
than the proportion received by any other Bank, the Bank receiving such
proportionately greater payment shall purchase such participations in the Notes
held by the other Banks, and such other adjustments shall be made, as may be
required so that all such payments of principal and interest with respect to the
Notes held by the Banks shall be shared by the Banks pro rata; provided that
nothing in this Section shall impair the right of any Bank to exercise any right
of setoff or counterclaim it may have to any deposits not received in connection
with the Loans and to apply the amount subject to such exercise to the payment
of indebtedness of the Borrower other than its indebtedness under the Notes. The
Borrower agrees, to the fullest extent it may effectively do so under applicable
law, that any holder of a participation in a Note, whether or not acquired
pursuant to the foregoing arrangements, may exercise rights of set-off or
counterclaim and other rights with respect to such participation as fully as if
such holder of a participation were a direct creditor of the Borrower in the
amount of such participation. Notwithstanding anything to the contrary contained
herein, any Bank may, by separate agreement with the Borrower, waive its right
to set off contained herein or granted by law and any such written waiver shall
be effective against such Bank under this Section 9.4.

               SECTION 9.5. Amendments and Waivers. Any provision of this
Agreement, the Notes or any other Loan Documents may be amended or waived if,
but only if, such amendment or waiver is in writing and is signed by the
Borrower and the Required Banks; provided that no such amendment or waiver with
respect to this Agreement, the Notes or any other Loan Documents shall, unless
signed by all the Banks, (i) subject any Bank to any additional obligation, (ii)
reduce the principal of or rate of interest on any Loan or any fees hereunder,
(iii) postpone the date fixed for any payment of principal of or interest on any
Loan or any fees hereunder, (iv) except as contemplated by this Agreement,
change the percentage of the Commitments or of the aggregate unpaid principal
amount of the Notes, or the number of Banks, which shall be required for the
Banks or any of them to take any action under this Section or any other
provision of this Agreement, release the Guaranty or (vi) modify the provisions
of this Section 9.5. No amendment or waiver shall be binding against the
Administrative Agent until it shall have been notified thereof in writing.

               SECTION 9.6.  Successors and Assigns.

               (a) The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns, except that the Borrower may not assign or otherwise transfer any of
its rights under this Agreement or the other Loan Documents without the prior
written consent of all Banks and the Administrative Agent and a Bank may not
assign or otherwise transfer any of its interest under this Agreement except as
permitted in subsection (b) and (c) of this Section 9.6.

               (b) Any Bank may at any time grant to any Person in any amount,
participating interests in any Loans made pursuant to this Agreement. In
addition, any Bank may at any time grant to any existing Bank or one or more
banks, finance companies, insurance or other financial institutions which (A)
has (or, in the case of a bank which is a subsidiary, such bank's parent has) a
rating of its senior debt obligations of not less than Baa-1 by Moody's, BBB by
S&P or a comparable rating by a rating agency acceptable to Administrative Agent
and (B) has total assets in excess of Ten Billion Dollars ($10,000,000,000),
participating interests in its Loan, in an amount not less than $10,000,000;
provided that such Bank retains at least one-half of its interest in its Loan
free and clear of any participation interest. If any Bank sells or grants an
interest to a Person described above (in each case, a "Participant"), (i) such
Bank shall make and receive all payments for the account of its Participant,
(ii) such Bank's obligations under this Agreement shall remain unchanged, (iii)
such Bank shall continue to be the sole holder of its Notes and other Loan
Documents subject to the participation and shall have the sole right to enforce
its rights and remedies under the Loan Documents, (iv) the Borrower, the
Administrative Agent and the Banks shall continue to deal solely and directly
with such Bank in connection with such Bank's rights and obligations under the
Loan Documents, and (v) the participation agreement shall not restrict such
Bank's ability to agree to any amendment of the terms of the Loan Documents, or
to exercise or refrain from exercising any powers or rights that such Bank may
have under or in respect of the Loan Documents, except that the Participant may
be granted the right to consent to any



                                       63
<PAGE>   71

(A) reduction of the rate or amount, or any extension of the stated maturity or
due date (except as to any extension of the Maturity Date provided for in this
Agreement), of any principal, interest or fees payable by the Borrower and
subject to the participation, or (B) release of the Guaranty, except to the
extent otherwise provided in the Loan Documents. The Borrower agrees that each
Participant shall, to the extent provided in its participation agreement, be
entitled to the benefits of Article VIII with respect to its participating
interest.

               (c) Subject to the requirement that each Bank continues to hold a
minimum of five percent (5%) of the Aggregate Commitments for so long as it is a
Bank hereunder, any Bank may at any time assign, prior to the occurrence of an
Event of Default, to an existing Bank or one or more banks, finance companies,
insurance or other financial institutions which (A) has (or, in the case of a
bank which is a subsidiary, such bank's parent has) a rating of its senior debt
obligations of not less than Baa-1 by Moody's, BBB by S&P or a comparable rating
by a rating agency acceptable to Administrative Agent and (B) has total assets
in excess of Ten Billion Dollars ($10,000,000,000), in minimum amounts of not
less than five percent (5%) of the Aggregate Commitments and integral multiples
of One Million Dollars ($1,000,000) thereafter (or any lesser amount in the case
of assignments to an existing Bank) so long as such assignment is made with (and
subject to) the consent of the Administrative Agent, which shall not be
unreasonably withheld or delayed; provided that if an Assignee is an affiliate
of such transferor Bank or was a Bank immediately prior to such assignment, no
such consent shall be required. After the occurrence and during the continuance
of an Event of Default, any Bank may at any time assign to any Person in any
amount, all or a proportionate part of all, of its rights and obligations under
this Agreement, the Notes and the other Loan Documents. In either case, such
Person (in each case, an "Assignee") shall assume such rights and obligations,
pursuant to a Transfer Supplement in substantially the form of Exhibit "B"
attached hereto executed by such Assignee and such transferor Bank, and a copy
thereof shall be promptly furnished to the Administrative Agent. Upon execution
and delivery of a Transfer Supplement and payment by such Assignee to such
transferor Bank of an amount equal to the purchase price agreed between such
transferor Bank and such Assignee, such Assignee shall be a Bank party to this
Agreement and shall have all the rights and obligations of a Bank with a
Commitment as set forth in such Transfer Supplement, and no further consent or
action by any party shall be required and the transferor Bank shall be released
from its obligations hereunder to a corresponding extent. Upon the consummation
of any assignment pursuant to this subsection (c), the transferor Bank, the
Administrative Agent and the Borrower shall make appropriate arrangements so
that, if required, new Notes are issued to the Assignee and to the transferor
Bank in replacement of its old Note. In connection with any such assignment, the
transferor Bank shall pay to the Administrative Agent an administrative fee for
processing such assignment in the amount of $2,500. If the Assignee is not
incorporated under the laws of the United States of America or a state thereof,
it shall deliver to the Borrower and the Administrative Agent certification as
to exemption from deduction or withholding of any United States federal, income
taxes in



                                       64
<PAGE>   72

accordance with Section 8.4. Any assignment, made during the continuation of an
Event of Default shall not be affected by any subsequent cure of such Event of
Default.

               (d) Any Bank may at any time assign all or any portion of its
rights under this Agreement and its Note to a Federal Reserve Bank. No such
assignment shall release the transferor Bank from its obligations hereunder.

               (e) No Assignee, Participant or other transferee of any Bank's
rights shall be entitled to receive any greater payment under Section 8.3 or 8.4
than such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.2, 8.3 or 8.4 requiring such
Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

               SECTION 9.7. Collateral. Each of the Banks represents to the
Administrative Agent and each of the other Banks that it in good faith is not
relying upon any "margin stock" (as defined in Regulation U) as collateral in
the extension or maintenance of the credit provided for in this Agreement.

               SECTION 9.8. Governing Law; Submission to Jurisdiction. THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE
PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE
GOVERNED BY THE LAWS OF THE STATE OF CALIFORNIA EXCEPT TO THE EXTENT PREEMPTED
BY FEDERAL LAW (WITHOUT GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO
CONFLICTS OF LAW).

               (b) Any legal action or proceeding with respect to this Agreement
or any other Loan Document and any action for enforcement of any judgment in
respect thereof may be brought in the courts of the State of California or of
the United States of America located in Orange County, California, and, by
execution and delivery of this Agreement, the Banks and the Borrower each hereby
accepts for itself and in respect of its property, generally and
unconditionally, the non-exclusive jurisdiction of the aforesaid courts and
appellate courts from any thereof. The Banks and the Borrower irrevocably
consent to the service of process out of any of the aforementioned courts in any
such action or proceeding by the hand delivery, or mailing of copies thereof by
registered or certified mail, postage prepaid, to the Banks and the Borrower at
their respective addresses set forth below. The Banks and the Borrower hereby
irrevocably waive any objection which it may now or hereafter have to the laying
of venue of any of the aforesaid actions or proceedings arising out of or in
connection with this Agreement or any other Loan Document brought in the courts
referred to above and hereby further irrevocably waive and agree not to plead or
claim in any such court that any such action or proceeding brought in any such
court has been brought in an inconvenient forum. Nothing herein shall affect the
right of the Borrower or Administrative Agent to serve



                                       65
<PAGE>   73

process in any other manner permitted by law or to commence legal proceedings or
otherwise proceed against any other party in any other jurisdiction.

               SECTION 9.9. Counterparts; Integration; Effectiveness. This
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument. This Agreement constitutes the entire agreement and
understanding among the parties hereto and supersedes any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof. This Agreement shall become effective upon receipt by the Administrative
Agent and the Borrower of counterparts hereof signed by each of the parties
hereto (or, in the case of any party as to which an executed counterpart shall
not have been received, receipt by the Administrative Agent in form satisfactory
to it of telegraphic, telex or other written confirmation from such party of
execution of a counterpart hereof by such party), and the date on which such
receipt occurs shall be the "Effective Date."

               SECTION 9.10. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE
ADMINISTRATIVE AGENT AND THE BANKS HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO
TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

               SECTION 9.11. Survival. All indemnities set forth herein shall
survive the execution and delivery of this Agreement and the other Loan
Documents and the making and repayment of the Loans hereunder.

               SECTION 9.12. Domicile of Loans. Each Bank may transfer and carry
its Loans at, to or for the account of any domestic or foreign branch office,
subsidiary or affiliate of such Bank.

               SECTION 9.13. Limitation of Liability. No claim may be made by
the Borrower or any other Person acting by or through Borrower against the
Administrative Agent or any Bank or the affiliates, directors, officers,
employees, attorneys or agent of any of them for any consequential or punitive
damages in respect of any claim for breach of contract or any other theory of
liability arising out of or related to the transactions contemplated by this
Agreement or by the other Loan Documents, or any act, omission or event
occurring in connection therewith; and the Borrower hereby waives, releases and
agrees not to sue upon any claim for any such damages, whether or not accrued
and whether or not known or suspected to exist in its favor.

               SECTION 9.14. Recourse Obligation. This Agreement and the
Obligations hereunder are fully recourse to the Borrower. Notwithstanding the
foregoing, no recourse under or upon any obligation, covenant, or agreement
contained in this Agreement shall be had against any limited partner of
Borrower, any shareholder of Guarantor or any of their or Borrower's or
Guarantor's respective officers, directors,



                                       66
<PAGE>   74

shareholders or employees except in the event of fraud or misappropriation of
funds on the part of such officer, director, shareholder or employee.

               SECTION 9.15.  Bank's Failure to Fund.

               (a) Unless the Administrative Agent shall have received notice
from a Bank prior to the Closing Date that such Bank will not make available to
the Administrative Agent such Bank's share of the initial Borrowing, the
Administrative Agent may assume that such Bank has made such share available to
the Administrative Agent on the date of such Borrowing in accordance with
subsection (a) of Section 2.2 hereof, and the Administrative Agent may, in
reliance upon such assumption, make available to Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Administrative Agent, such Bank and Borrower
severally agree to repay to the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, in accordance with the
provisions of Section 2.2(b) hereof. If such Bank shall repay to the
Administrative Agent such corresponding amount, such amount so repaid shall
constitute such Bank's Loan included in such Borrowing for purposes of this
Agreement. Nothing contained in this Section or Section 2.2(b) shall be deemed
to reduce the Commitment of any Bank or in any way affect the rights of Borrower
with respect to any defaulting Bank or Administrative Agent. The failure of any
Bank to make available to the Administrative Agent such Bank's share of the
initial Borrowing in accordance with Section 2.2(a) hereof shall not relieve any
other Bank of its obligations to fund its Commitment, in accordance with the
provisions hereof.

               (b) If a Bank does not advance to Administrative Agent such
Bank's pro rata share of the initial Borrowing in accordance herewith, then
neither Administrative Agent nor the other Banks shall be required or obligated
to fund such Bank's pro rata share of such initial Borrowing.

               (c) As used herein, the following terms shall have the meanings
set forth below:

                     (i) "Defaulting Bank" shall mean any Bank which (x) does 
not advance to the Administrative Agent such Bank's pro rata share of the
initial Borrowing in accordance herewith for a period of five (5) Domestic
Business Days after notice of such failure from Administrative Agent, (y) shall
otherwise fail to perform such Bank's obligations under the Loan Documents for a
period of five (5) Domestic Business Days after notice of such failure from
Administrative Agent, or (z) shall fail to pay the Administrative Agent or any
other Bank, as the case may be, upon demand, such Bank's pro rata share of any
costs, expenses or disbursements incurred or made by the Administrative Agent
pursuant to the terms of the Loan Documents for a period of five (5) Domestic
Business Days after notice of such failure from Administrative Agent, and in all
cases, such failure is not as a result of a good faith dispute as to whether
such advance is properly required to be made pursuant to the provisions of this
Agreement, or



                                       67
<PAGE>   75

as to whether such other performance or payment is properly required pursuant to
the provisions of this Agreement.

                    (ii) "Junior Creditor" means any Defaulting Bank which has
not (x) fully cured each and every default on its part under the Loan Documents
and (y) unconditionally tendered to the Administrative Agent such Defaulting
Bank's pro rata share of all costs, expenses and disbursements required to be
paid or reimbursed pursuant to the terms of the Loan Documents.

                   (iii) "Payment in Full" means, as of any date, the receipt by
the Banks who are not Junior Creditors of an amount of cash, in lawful currency
of the United States, sufficient to indefeasibly pay in full all Senior Debt.

                    (iv) "Senior Debt" means (x) collectively, any and all
indebtedness, obligations and liabilities of the Borrower to the Banks who are
not Junior Creditors from time to time, whether fixed or contingent, direct or
indirect, joint or several, due or not due, liquidated or unliquidated,
determined or undetermined, arising by contract, operation of law or otherwise,
whether on open account or evidenced by one or more instruments, and whether for
principal, premium, interest (including, without limitation, interest accruing
after the filing of a petition initiating any proceeding referred to in Section
6.1(f) or (g)), reimbursement for fees, indemnities, costs, expenses or
otherwise, which arise under, in connection with or in respect of the Loans or
the Loan Documents, and (y) any and all deferrals, renewals, extensions and
refundings of, or amendments, restatements, rearrangements, modifications or
supplements to, any such indebtedness, obligation or liability.

                    (v)  "Subordinated Debt" means (x) any and all indebtedness,
obligations and liabilities of Borrower to one or more Junior Creditors from
time to time, whether fixed or contingent, direct or indirect, joint or several,
due or not due, liquidated or unliquidated, determined or undetermined, arising
by contract, operation of law or otherwise, whether on open account or evidenced
by one or more instruments, and whether for principal, premium, interest
(including, without limitation, interest accruing after the filing of a petition
initiating any proceeding referred to in Section 6.1(f) or (g)), reimbursement
for fees, indemnities, costs, expenses or otherwise, which arise under, in
connection with or in respect of the Loans or the Loan Documents, and (y) any
and all deferrals, renewals, extensions and refundings of, or amendments,
restatements, rearrangements, modifications or supplements to, any such
indebtedness, obligation or liability.

               (d) Immediately upon a Bank's becoming a Junior Creditor, no
Junior Creditor shall, prior to Payment in Full of all Senior Debt:

                     (i)   accelerate, demand payment of, sue upon, collect, or
receive any payment upon, in any manner, or satisfy or otherwise discharge, any
Subordinated Debt, whether for principal, interest and otherwise;



                                       68
<PAGE>   76

                    (ii) take or enforce any Liens to secure Subordinated Debt
or attach or levy upon any assets of Borrower, to enforce any Subordinated Debt;

                   (iii) enforce or apply any security for any Subordinated
Debt; or

                    (iv) incur any debt or liability, or the like, to, or
receive any loan, return of capital, advance, gift or any other property, from,
the Borrower.

               (e) In the event of:

                     (i) any insolvency, bankruptcy, receivership, liquidation,
dissolution, reorganization, readjustment, composition or other similar
proceeding relating to Borrower;

                    (ii) any liquidation, dissolution or other winding-up of the
Borrower, voluntary or involuntary, whether or not involving insolvency,
reorganization or bankruptcy proceedings;

                   (iii) any assignment by the Borrower for the benefit of
creditors;

                    (iv) any sale or other transfer of all or substantially all
assets of the Borrower; or

                     (v) any other marshaling of the assets of the Borrower;

each of the Banks shall first have received Payment in Full of all Senior Debt
before any payment or distribution, whether in cash, securities or other
property, shall be made in respect of or upon any Subordinated Debt. Any payment
or distribution, whether in cash, securities or other property that would
otherwise be payable or deliverable in respect of Subordinated Debt to any
Junior Creditor but for this Agreement shall be paid or delivered directly to
the Administrative Agent for distribution to the Banks in accordance with this
Agreement until Payment in Full of all Senior Debt. If any Junior Creditor
receives any such payment or distribution, it shall promptly pay over or deliver
the same to the Administrative Agent for application in accordance with the
preceding sentence.

               (f) Each Junior Creditor shall file in any bankruptcy or other
proceeding of Borrower in which the filing of claims is required by law, all
claims relating to Subordinated Debt that such Junior Creditor may have against
Borrower and assign to the Banks who are not Junior Creditors all rights of such
Junior Creditor thereunder. If such Junior Creditor does not file any such claim
prior to forty-five (45) days before the expiration of the time to file such
claim, Administrative Agent, as attorney-in-fact for such Junior Creditor, is
hereby irrevocably authorized to do so in the name of such Junior Creditor or,
in Administrative Agent's sole discretion, to assign the claim to a nominee and
to cause proof of claim to be filed in the name of such nominee. The foregoing
power of attorney is coupled with an interest and cannot be revoked. The
Administrative Agent shall, to the exclusion of each Junior Creditor, have the
sole right,



                                       69
<PAGE>   77

subject to Section 9.5 hereof, to accept or reject any plan proposed in any such
proceeding and to take any other action that a party filing a claim is entitled
to take. In all such cases, whether in administration, bankruptcy or otherwise,
the Person or Persons authorized to pay such claim shall pay to Administrative
Agent the amount payable on such claim and, to the full extent necessary for
that purpose, each Junior Creditor hereby transfers and assigns to the
Administrative Agent all of the Junior Creditor's rights to any such payments or
distributions to which Junior Creditor would otherwise be entitled.

               (g) (i) If any payment or distribution of any character or any
security, whether in cash, securities or other property, shall be received by
any Junior Creditor in contravention of any of the terms hereof, such payment or
distribution or security shall be received in trust for the benefit of, and
shall promptly be paid over or delivered and transferred to, Administrative
Agent for application to the payment of all Senior Debt, to the extent necessary
to achieve Payment in Full. In the event of the failure of any Junior Creditor
to endorse or assign any such payment, distribution or security, Administrative
Agent is hereby irrevocably authorized to endorse or assign the same as
attorney-in-fact for such Junior Creditor.

                    (ii) Each Junior Creditor shall take such action (including,
without limitation, the execution and filing of a financing statement with
respect to this Agreement and the execution, verification, delivery and filing
of proofs of claim, consents, assignments or other instructions that
Administrative Agent may require from time to time in order to prove or realize
upon any rights or claims pertaining to Subordinated Debt or to effectuate the
full benefit of the subordination contained herein) as may, in Administrative
Agent's sole and absolute discretion, be necessary or desirable to assure the
effectiveness of the subordination effected by this Agreement.

               (h) (i) Each Bank that becomes a Junior Creditor understands and
acknowledges by its execution hereof that each other Bank is entering into this
Agreement and the Loan Documents in reliance upon the absolute subordination in
right of payment and in time of payment of Subordinated Debt to Senior Debt as
set forth herein.

                   (ii) Only upon the Payment in Full of all Senior Debt shall
any Junior Creditor be subrogated to any remaining rights of the Banks which are
not Defaulting Banks to receive payments or distributions of assets of the
Borrower made on or applicable to any Senior Debt.

                   (iii) Each Junior Creditor agrees that it will deliver all
instruments or other writings evidencing any Subordinated Debt held by it to
Administrative Agent, promptly after request therefor by the Administrative
Agent.

                    (iv) No Junior Creditor may at any time sell, assign or
otherwise transfer any Subordinated Debt, or any portion thereof, including,
without limitation, the granting of any Lien thereon, unless and until
satisfaction of the requirements of Section 9.6 above and the proposed
transferee shall have assumed in writing the



                                       70
<PAGE>   78

obligation of the Junior Creditor to the Banks under this Agreement, in a form
acceptable to the Administrative Agent.

                     (v) If any of the Senior Debt, should be invalidated,
avoided or set aside, the subordination provided for herein nevertheless shall
continue in full force and effect and, as between the Banks which are not
Defaulting Banks and all Junior Creditors, shall be and be deemed to remain in
full force and effect.

                    (vi) Each Junior Creditor hereby irrevocably waives, in
respect of Subordinated Debt, all rights (x) under Sections 361 through 365,
502(e) and 509 of the Bankruptcy Code (or any similar sections hereafter in
effect under any other Federal or state laws or legal or equitable principles
relating to bankruptcy, insolvency, reorganizations, liquidations or otherwise
for the relief of debtors or protection of creditors), and (y) to seek or obtain
conversion to a different type of proceeding or to seek or obtain dismissal of a
proceeding, in each case in relation to a bankruptcy, reorganization, insolvency
or other proceeding under similar laws with respect to the Borrower. Without
limiting the generality of the foregoing, each Junior Creditor hereby
specifically waives (A) the right to seek to give credit (secured or otherwise)
to the Borrower in any way under Section 364 of the Bankruptcy Code unless the
same is subordinated in all respects to Senior Debt in a manner acceptable to
Administrative Agent in its sole and absolute discretion and (B) the right to
receive any collateral security (including any "super priority" or equal or
"priming" or replacement Lien) for any Subordinated Debt unless the Banks which
are not Defaulting Banks have received a senior position acceptable to the Banks
in their sole and absolute discretion to secure all Senior Debt (in the same
collateral to the extent collateral is involved).

               (i) (i) In addition to and not in limitation of the subordination
effected by this Section 9.15, the Administrative Agent and each of the Banks
which are not Defaulting Banks may in their respective sole and absolute
discretion, also exercise any and all other rights and remedies available at law
or in equity in respect of a Defaulting Bank; and

                    (ii) The Administrative Agent shall give each of the Banks
notice of the occurrence of a default under this Section 9.15 by a Defaulting
Bank and if the Administrative Agent and/or one or more of the other Banks
shall, at their option, fund any amounts required to be paid or advanced by a
Defaulting Bank, the other Banks who have elected not to fund any portion of
such amounts shall not be liable for any reimbursements to the Administrative
Agent and/or to such other funding Banks.

               (j) Notwithstanding anything to the contrary contained or implied
herein, a Defaulting Bank shall not be entitled to vote on any matter as to
which a vote by the Banks is required hereunder, including, without limitation,
any actions or consents on the part of the Administrative Agent as to which the
approval or consent of all the Banks or the Required Banks is required under
Article VIII, Section 9.5 or elsewhere, so long as such Bank is a Defaulting
Bank; provided, however, that in the case of any vote requiring



                                       71
<PAGE>   79

the unanimous consent of the Banks, if all the Banks other than the Defaulting
Bank shall have voted in accordance with each other, then the Defaulting Bank
shall be deemed to have voted in accordance with such Banks.

               (k) Each of the Administrative Agent and any one or more of the
Banks which are not Defaulting Banks may, at their respective option, (i)
advance to the Borrower such Bank's pro rata share of the portion of the initial
Borrowing not advanced by a Defaulting Bank in accordance with the Loan
Documents, or (ii) pay to the Administrative Agent such Bank's pro rata share of
any costs, expenses or disbursements incurred or made by the Administrative
Agent pursuant to the terms of this Agreement not theretofore paid by a
Defaulting Bank. Immediately upon the making of any such advance by the
Administrative Agent or any one of the Banks, such Bank's pro rata share and the
pro rata share of the Defaulting Bank shall be recalculated to reflect such
advance. All payments, repayments and other disbursements of funds by the
Administrative Agent to Banks shall thereupon and, at all times thereafter be
made in accordance with such Bank's recalculated pro rata share unless and until
a Defaulting Bank shall fully cure all defaults on the part of such Defaulting
Bank under the Loan Documents or otherwise existing in respect of the Loans or
this Agreement, at which time the pro rata share of the Bank(s) which advanced
sums on behalf of the Defaulting Bank and of the Defaulting Bank shall be
restored to their original percentages.

               SECTION 9.16.  Dispute Resolution.

               (a)    Mandatory Arbitration

                      (i) If requested by any party thereto, any controversy or
claim between the parties hereto arising out of or relating to this Agreement or
any of the other Loan Documents (including any controversy or claim regarding
the arbitrability of such controversy or claim or based on or arising out of an
alleged tort) shall be determined by arbitration to be held in Orange County,
California in accordance with Title 9 of the U.S. Code and the Commercial
Arbitration Rules of the American Arbitration Association (the "AAA") and the
AAA's Supplementary Procedures for Large, Complex Disputes.

                      (ii) Any arbitration hereunder shall be held before a
single arbitrator mutually agreed to by the parties thereto, except that, if the
parties shall fail to agree to such an arbitrator within ten (10) days from the
date on which the claimant's request for arbitration is delivered to the other
party to the arbitration, such arbitration shall be held before a panel of three
arbitrators and each party shall appoint one arbitrator. The arbitrator(s) must
be either a retired judge from the California Superior or Appellate Courts or
the United States District Courts located in California or a member of the AAA
panel for hearing large, complex cases in Orange County, California. If a party
fails to nominate an arbitrator within 10 days from the date on which the
claimant's request for arbitration has been communicated to the other party, the
appointment shall be made by the AAA. The two arbitrators so appointed shall
attempt to agree upon the third arbitrator to act as chairman. If the two
arbitrators fail to nominate the chairman within 10 days



                                       72
<PAGE>   80

from the date of appointment of the later appointed arbitrator, the chairman
shall be selected by the AAA.

                      (iii) Discovery may be taken in the arbitration
proceedings pursuant to the provisions of California Code of Civil Procedure
Section 1283.05, which are incorporated herein by reference and made applicable
to any arbitration held pursuant to this Section.

                      (iv) The award of the arbitrator(s) shall be final, and
the parties agree to waive their right to any form of appeal, to the greatest
extent allowed by law, and to share equally the fees and expenses of the
arbitrators. Judgment upon any award of the arbitrators may be entered in any
court having jurisdiction or application may be made to such court for the
judicial acceptance of the award and for order of enforcement. All statutes of
limitation and waivers that would otherwise be applicable shall apply to any
arbitration proceeding under this Section 9.16(a).

               (b)    Judicial Reference

               If any such controversy or claim is not submitted to arbitration
as provided in subsection (a), but becomes the subject of a judicial action, it
shall be resolved solely and exclusively pursuant to the provisions for
reference and trial by referee set forth in California Code of Civil Procedure
Section 638 et seq., or any statute containing reasonably similar provisions
that replaces such sections, except as expressly modified by the provisions
hereof. The referee shall be a retired or former Superior Court judge practicing
in Orange County, California, who is either (i) agreed to by the parties within
ten (10) days of the notice by any party to the other of the intention to invoke
this Section to resolve the dispute, or (ii) failing such agreement, is
appointed pursuant to California Code of Civil Procedure Section 638.l (or any
statute containing reasonably similar provisions that replaces such section) in
an action filed in the Superior Court of Orange County, California. The parties
agree that any party may file (and, if necessary, the other party shall join in
such filing) with the Clerk of the Orange County Superior Court, or with the
appropriate judge of such Court, any and all petitions, motions, applications or
other documents necessary to obtain the appointment of such a referee
immediately upon the commencement of any action or proceeding to resolve any
such dispute and to conduct all necessary discovery and to proceed to a trial as
expeditiously as possible. All proceedings, including trial, before the referee
shall be conducted at a neutral location (unless otherwise stipulated by the
parties) within five miles of the Orange County Superior Court. The parties
agree that the referee shall be a judge for all purposes (including (i) ruling
on any and all discovery matters and motions and any and all pretrial or trial
motions, (ii) setting a schedule of pretrial proceedings, and (iii) making any
other orders or rulings a sitting judge of the Superior Court would be empowered
to make in any action or proceeding in the Superior Court). Any matter before
the referee shall be governed by the California Code of Civil Procedure, the
California Rules of Court, the California Evidence Code and the Local Rules of
the Orange County Superior Court. Any decision of the referee shall be
appealable to the same extent and in the same manner



                                       73
<PAGE>   81

that such decisions would be appealable if rendered by a judge of the Orange
County Superior Court. The Referee shall in his or her statement of decision set
forth his or her findings of fact and conclusions of law. The parties intend
this reference agreement to be specifically enforceable in accordance with
Section 638.l of the California Code of Civil Procedure.

               (c)    Provisional Remedies, Self-Help

               Subject to Section 9.4, nothing herein shall limit the right of
any party to exercise self-help remedies such as setoff or to obtain provisional
or ancillary remedies, including an order of attachment, a temporary restraining
order, preliminary injunction or other interim relief from any court of
competent jurisdiction if such is necessary to preserve that party's rights
before, during or after the pendency of any arbitration, reference or bankruptcy
proceeding.

$______________                                                November 20, 1998

               For value received, IRVINE APARTMENT COMMUNITIES, L.P., a
Delaware limited partnership (the "Borrower"), promises to pay to the order of
__________________ (the "Bank"), for the account of its Applicable Lending
Office, the principal sum of _______________ ($________). The Borrower promises
to pay interest on the unpaid principal amount of the Loan owing to the Bank on
the dates and at the rate or rates provided for in the Loan Agreement referred
to below. All such payments of principal and interest shall be made in lawful
money of the United States in Federal or other immediately available funds at
the office designated by Bank.

               Any Loan made by the Bank, the type and maturity thereof and all
repayments of the principal thereof shall be recorded by the Bank and, if the
Bank so elects in connection with any transfer or enforcement hereof,
appropriate notations to evidence the foregoing information with respect to such
Loan then outstanding may be endorsed by the Bank on the schedule attached
hereto, or on a continuation of such schedule attached to and made a part
hereof; provided that the failure of the Bank to make any such recordation or
endorsement shall not affect the obligations of the Borrower hereunder or under
the Loan Agreement.

               This note is one of the Notes referred to in, and is delivered
pursuant to and subject to all of the terms of, the Unsecured Loan Agreement
dated as of November 20, 1998 by and among the Borrower, the banks listed on the
signature pages thereof, Wells Fargo Bank, N.A., as Co-Arranger and
Administrative Agent, and U.S. Bank National Association, as Co-Arranger (as the
same may be amended, supplemented, replaced, renewed or otherwise modified from
time to time, the "Loan Agreement"). Terms defined in the Loan Agreement are
used herein with the same meanings.

        7.   This Transfer Supplement may be executed in any number of
counterparts which, when taken together, shall be deemed to constitute one and
the same instrument.

        8.   The Assignor hereby represents and warrants to the Purchasing

                                       B-3
<PAGE>   99

from claims by any broker or finder that such broker or finder has dealt with
said party in connection with this transaction.

        11.   Subject to the provisions of Paragraph 12 hereof, if, with

indemnify and hold harmless the other, each of its directors and each of its
officers in connection with any claim or cause of action based on any matter or
claim based on the acts of either while acting as a Bank under the Loan
Agreement. Promptly after receipt by the indemnified party under this Section of
notice of the commencement of any action, such indemnified party shall notify
the indemnifying party in writing of the commencement thereof. If any such
action is brought against any indemnified party and that party notifies the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein, and to the extent that it may elect by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof, with counsel
satisfactory to such indemnified party, and after receipt of notice from the
indemnifying party to such indemnified party of its election to so assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof. In no event
shall the indemnified party settle or consent to a settlement of such cause of
action or claim without the consent of the indemnifying party.

TO:    Wells Fargo Bank, N.A.

Reference is hereby made to the Unsecured Loan Agreement, dated as of November

APARTMENT COMMUNITIES, L.P., a Delaware limited partnership (the "Borrower"),
the Banks listed therein, WELLS FARGO BANK, N.A., as Co-Arranger and

This Compliance Certificate is being delivered by the Borrower pursuant to
Section 5.1(c) of the Loan Agreement and relates to certain financial statements
of the Borrower (the "Financial Statements") as of and for periods ended
_________________, ______ (the "Financial Statement Date"). The undersigned is
the __________________ [insert title of Certifying Officer] of the sole general
partner of the Borrower, and hereby further certifies as of the date hereof, in
his capacity as an officer of the general partner of the Borrower, as follows:

        1.     I have reviewed the terms of the Loan Documents and have made, or
               have caused to be made under my supervision, a review in
               reasonable detail of the transactions and condition of the
               Borrower Parties during the accounting period covered by the
               Financial Statements.

        2.     Such review has not disclosed the existence of any Default or
               Event of Default during such accounting period or as of the
               Financial Statement Date and I do not have knowledge of the
               existence, as at the date of this certificate, of any Default or
               Event of Default.

        3.     Attached as Appendix A hereto are calculations by which I have
               determined that the Borrower is in compliance with the
               requirements of Section 5.9 of the Loan Agreement as of the
               Financial Statement Date.

        4.     The Financial Statements fairly present the financial condition
               and the results of operations of the Borrower on the dates and
               for the periods indicated, on the basis of GAAP.

        5.     The Borrower is in compliance with the Interest Rate Hedge
               requirements set forth in Section 5.13 of the Loan Agreement.

January 22, 1999


Mr. William H. McFarland
6 Weymouth Court
Newport Beach, CA 92660


Dear Bill:

         The Board of Directors of Irvine Apartment Communities, Inc. believes
that in the event of a business combination involving IAC, continuity of
effective management will be critical to the best interests of the Company and
its shareholders. In order to induce you to remain in the Company's employ
throughout any period of uncertainty associated with a proposed business
combination, therefore, the Special Committee of the Board of Directors has
adopted the measures described in this letter agreement. This letter agreement
relates to, among other things, your stock option and restricted stock unit and
performance unit awards granted under the Company's 1993 and 1996 Long-Term
Stock Incentive Plans (collectively, the "PLAN") and supplements the provisions
in the Plan and in the respective Award Agreements. Capitalized terms used in
this letter shall have the same meanings as in the Plan.

Stock Options:      In the event of a Transaction, as defined below, all
                    outstanding Options then held by you shall be canceled as of
                    the date of such Transaction. For each Share underlying such
                    Option, you will be entitled to receive the excess, if any,
                    of (i) the amount or value per share to be received by the
                    Company's stockholders in connection with such Transaction
                    (the "TRANSACTION PRICE") over (ii) the exercise price for
                    such Share under the terms of the relevant Award Agreement.
                    With respect to Options that were already vested as of the
                    date of such Transaction, such amounts will be paid to you
                    in cash as soon as practicable following the Transaction.
                    With respect to Options that were not vested at the time of
                    the Transaction, such amounts shall be paid to you in cash
                    at the time such awards would otherwise have vested pursuant
                    to the terms of the respective Award Agreements, as long as
                    you remain continuously employed by the Company until such
                    payment date, except as described below.

                    have been available for vesting or if sooner, until payment
                    for such Units and Future Units is made in accordance with
                    this letter agreement. Interest will be payable to you in
                    cash as promptly as practicable following each interest
                    payment date.

                    Company representing 20% or more of the combined voting
                    power of the Company's then outstanding securities;

                           (ii) During any period of two consecutive years
                    commencing on the date hereof, individuals who at the
                    beginning of such period constitute the Board, and any new

                    obtained.

Acceleration of     In the event your employment is terminated involuntarily by
Payment:            the Company without Cause, as defined below, or by yourself

                    within 10 days, after the date of your termination of
                    employment.

                    "CAUSE" shall mean (i) your willful and continued failure
                    substantially to perform the duties of your position (other
                    than as a result of total or partial incapacity due to
                    physical or mental illness or as a result of a termination
                    of employment by you for Good Reason), (ii) any willful act
                    or omission by you constituting dishonesty, fraud or other
                    malfeasance, which in any such case is demonstrably
                    injurious to the financial condition or business reputation
                    of the Company or any of its affiliates, or (iii) your
                    conviction of, or plea of guilty or nolo contendere to, a
                    felony under the laws of the United States or any state
                    thereof or any other jurisdiction in which the Company or
                    any of its subsidiaries conducts business. For purposes of
                    this definition, no act or failure to act shall be deemed
                    "willful" unless effected by you not in good faith and
                    without a reasonable belief that such action or failure to
                    act was in or not opposed to the best interests of the
                    Company.

                    "GOOD REASON" shall mean:

                           (i) Removal from, or failure to be reappointed or
                    reelected to, your position (other than as a result of a
                    promotion);

                           (ii) Material diminution in your position or
                    responsibilities, such as would amount effectively to a
                    demotion;

                           (iii) Reduction in your base salary or maximum annual
                    bonus opportunity, or breach by the Company of any of the
                    provisions of this letter agreement; or

                           (iv) Relocation of your principal workplace without
                    your consent to a location outside the Newport Beach area.

Severance Payment:  In the event your employment is terminated involuntarily by
                    the Company without Cause, or by yourself for Good Reason
                    within eighteen months following a Transaction, you shall be
                    entitled to one year's Base Salary at the rate in



                                        4

                    effect at the time of such termination of employment, or if
                    higher, at the rate in effect at the date of the
                    Transaction. Such amount shall be paid to you in lump sum,
                    without reduction for the time value of money, as soon as
                    practicable, but in any event within 10 days after the date
                    of your termination of employment.

Certain Tax         The Company believes that no amount which you may receive
Matters:            hereunder in connection with the proposed acquisition of the
                    Company by The Irvine Company would be treated as being
                    contingent on a change in ownership or effective control of
                    the Company, for purposes of the application of the "golden
                    parachute" excise tax provisions of the Internal Revenue
                    Code. The Company agrees to take a position consistent with
                    such belief in all matters dealing with the Internal Revenue
                    Service and to refrain from taking any action or position
                    that would be inconsistent with or otherwise undermine such
                    position. In the event that it is ultimately determined by
                    controlling tax authority that amounts received by you
                    hereunder are contingent on a change in ownership or
                    effective control of the Company for purposes of Sections
                    280G and 4999 of the Internal Revenue Code, then,
                    notwithstanding any other provision of this letter
                    agreement, you shall not be entitled to receive the excess,
                    if any, of (i) the total aggregate amount that you received
                    or are apparently entitled to receive hereunder (but for the
                    operation of this paragraph) over (ii) the maximum amount
                    you could have received in connection with such Transaction
                    without incurring excise tax under Section 4999 of the
                    Internal Revenue Code. Such excess amount, if paid to you
                    prior to such determination, shall be then immediately due
                    and owing to the Company.

Legal Expenses:     In the event that it becomes necessary for you to engage
                    legal counsel to pursue a legal remedy for the Company's
                    breach of any provision of this letter agreement, the
                    Company will reimburse you for the fees and expenses of such
                    counsel, when and as incurred by you, unless your claim is
                    determined by a court or arbitrator to be without merit.

[Executive's Name]
[Each Executive's Address]


Dear Sir:

         The Board of Directors of Irvine Apartment Communities, Inc. believes
that in the event of a business combination involving IAC, continuity of
effective management will be critical to the best interests of the Company and
its shareholders. In order to induce you to remain in the Company's employ
throughout any period of uncertainty associated with a proposed business
combination, therefore, the Special Committee of the Board of Directors has
adopted the measures described in this letter agreement. This letter agreement
relates to, among other things, your stock option and restricted stock unit and
performance unit awards granted under the Company's 1993 and 1996 Long-Term
Stock Incentive Plans (collectively, the "PLAN") and supplements the provisions
in the Plan and in the respective Award Agreements. Capitalized terms used in
this letter shall have the same meanings as in the Plan.

Stock Options:      In the event of a Transaction, as defined below, all
                    outstanding Options then held by you shall be canceled as of
                    the date of such Transaction. For each Share underlying such
                    Option, you will be entitled to receive the excess, if any,
                    of (i) the amount or value per share to be received by the
                    Company's stockholders in connection with such Transaction
                    (the "TRANSACTION PRICE") over (ii) the exercise price for
                    such Share under the terms of the relevant Award Agreement.
                    With respect to Options that were already vested as of the
                    date of such Transaction, such amounts will be paid to you
                    in cash as soon as practicable following the Transaction.
                    With respect to Options that were not vested at the time of
                    the Transaction, such amounts shall be paid to you in cash
                    at the time such awards would otherwise have vested pursuant
                    to the terms of the respective Award Agreements, as long as
                    you remain continuously employed by the Company until such
                    payment date, except as described below.

Restricted Stock    In the event of a Transaction, all of your outstanding
Unit and            Restricted Stock Units and Performance Awards ("UNITS")
Performance         shall be canceled as of the date of such Transaction. For
Awards:


<PAGE>   2
                    each such Unit, you shall be entitled to receive the
                    Transaction Price, which amount will be paid at the time
                    such awards would otherwise have been available for vesting
                    pursuant to the terms of the respective Award Agreements,
                    whether or not any applicable FAD targets are in fact
                    satisfied, as long as you remain continuously employed by
                    the Company until such payment date, except as described
                    below. Such amounts will bear interest from the date of the
                    Transaction to the date of payment, payable on the last day
                    of each calendar quarter, at the rate of 5% through February
                    29, 2000, and at 6% from March 1, 2000 until the date such
                    Unit would have been available for vesting or if sooner,
                    until payment for such Units is made in accordance with this
                    letter agreement. Interest will be payable to you in cash as
                    promptly as practicable following each interest payment
                    date.

                    following events:

                           (i) Any "person," as such term is used in Section

                    employee benefit plan of the Company) is or becomes the
                    "beneficial owner" (as defined in Rule 13d-3 under the
                    Exchange Act), directly or indirectly, of securities of the
                    Company representing 20% or more of the combined voting
                    power of the Company's then outstanding securities;

                           (ii) During any period of two consecutive years
                    commencing on the date hereof, individuals who at the
                    beginning of such period constitute the Board, and any new
                    director (other than a director designated by a person (as
                    defined above) who has entered into an agreement with the
                    Company to effect a transaction described in sections (i),
                    (iii) or (iv) of this definition) whose election by the
                    Board or nomination for election by the Company's
                    shareholders was approved by a vote of at least two-thirds
                    (2/3) of the directors then still in office who either were
                    directors at the beginning of the period or whose election
                    or nomination for election was previously so approved, cease
                    for any reason to constitute at least a majority thereof;

                           (iii) The shareholders of the Company have approved a
                    merger or consolidation of the Company with


       
<PAGE>   3

                    any other company and all other required governmental
                    approvals of such merger or consolidation have been
                    obtained, other than (A) a merger or consolidation which
                    would result in the voting securities of the Company
                    outstanding immediately prior thereto continuing to
                    represent (either by remaining outstanding or by being
                    converted into voting securities of the surviving entity)
                    more than 60% of the combined voting power of the voting
                    securities of the Company or such surviving entity

                    or (B) a merger or consolidation effected to implement a
                    recapitalization of the Company (or similar transaction) in

                    voting power of the Company's then outstanding securities;

                    substantially all of the Company's assets, and all other
                    governmental approvals of such transaction have been
                    obtained.

Acceleration of     In the event your employment is terminated involuntarily
Payment:            by the Company without Cause, as defined below, or by
                    yourself for Good Reason, as defined below, prior to the
                    date of payment of the value of outstanding unvested Options
                    and Units (as provided above), the payment of the value of
                    such awards as described herein will be made as promptly as
                    practicable, but in any event within 10 days, after the date
                    of your termination of employment.

                    "CAUSE" shall mean (i) your willful and continued failure
                    substantially to perform the duties of your position (other
                    than as a result of total or partial incapacity due to
                    physical or mental illness or as a result of a termination
                    of employment by you for Good Reason), (ii) any willful act
                    or omission by you constituting dishonesty, fraud or other
                    malfeasance, which in any such case is demonstrably
                    injurious to the financial condition or business reputation
                    of the Company or any of its affiliates, or (iii) your
                    conviction of, or plea of guilty or nolo contendere to, a
                    felony under the laws of the United States or any state
                    thereof or any




<PAGE>   4

                    other jurisdiction in which the Company or any of its
                    subsidiaries conducts business. For purposes of this
                    definition, no act or failure to act shall be deemed
                    "willful" unless effected by you not in good faith and
                    without a reasonable belief that such action or failure to
                    act was in or not opposed to the best interests of the
                    Company.

                    "GOOD REASON" shall mean:

                           (i) Removal from, or failure to be reappointed or
                    reelected to, your position (other than as a result of a
                    promotion);

                           (ii) Material diminution in your position or
                    responsibilities, such as would amount effectively to a
                    demotion;

                           (iii) Reduction in your base salary or maximum annual
                    bonus opportunity, or breach by the Company of any of the
                    provisions of this letter agreement; or

                           (iv) Relocation of your principal workplace without
                    your consent to a location outside the general area where
                    you are currently employed.

Severance Payment:  In the event your employment is terminated involuntarily by
                    the Company without Cause, or by yourself for Good Reason
                    within eighteen months following a Transaction, you shall be
                    entitled to one year's Base Salary at the rate in effect at
                    the time of such termination of employment, or if higher, at
                    the rate in effect on the date of the Transaction. Such
                    amount shall be paid to you in lump sum, without reduction
                    for the time value of money, as soon as practicable, but in
                    any event within 10 days, after the date of your termination
                    of employment.

Certain Tax         The Company believes that no amount which you may receive
Matters:            hereunder in connection with the proposed acquisition of the
                    Company by The Irvine Company would be treated as being
                    contingent on a change in ownership or effective control of
                    the Company, for purposes of the application of the "golden
                    parachute" excise tax provisions of the Internal Revenue
                    Code. The Company agrees to take a position consistent with
                    such belief in all matters dealing with the Internal Revenue
                    Service and




<PAGE>   5

                    to refrain from taking any action or position that would be
                    inconsistent with or otherwise undermine such position. In
                    the event that it is ultimately determined by controlling
                    tax authority that amounts received by you hereunder are
                    contingent on a change in ownership or effective control of
                    the Company for purposes of Sections 280G and 4999 of the
                    Internal Revenue Code, then, notwithstanding any other
                    provision of this letter agreement, you shall not be
                    entitled to receive the excess, if any, of (i) the total
                    aggregate amount that you received or are apparently
                    entitled to receive hereunder (but for the operation of this
                    paragraph) over (ii) the maximum amount you could have
                    received in connection with such Transaction without
                    incurring excise tax under Section 4999 of the Internal
                    Revenue Code. Such excess amount, if paid to you prior to
                    such determination, shall be then immediately due and owing
                    to the Company.

Legal Expenses:     In the event that it becomes necessary for you to engage
                    legal counsel to pursue a legal remedy for the Company's
                    breach of any provision of this letter agreement, the
                    Company will reimburse you for the fees and expenses of such
                    counsel, when and as incurred by you, unless your claim is
                    determined by a court or arbitrator to be without merit.

         Please indicate your acceptance of the provisions of this letter
agreement by signing and returning the duplicate of this letter to Shawn Howie.
If you have any questions, please do not hesitate to contact me.


Sincerely,



William H. McFarland
Chief Executive Officer

I understand and accept the terms set forth in this letter agreement.

January 22, 1999


[Award Holder's Name]
[Award Holder's Address]




Dear Sir:

         The Board of Directors of Irvine Apartment Communities, Inc. believes
that in the event of a business combination involving IAC, continuity of
effective management will be critical to the best interests of the Company and
its shareholders. In order to induce you to remain in the Company's employ
throughout any period of uncertainty associated with a proposed business
combination, therefore, the Special Committee of the Board of Directors has
adopted the measures described in this letter agreement. This letter agreement
relates to your stock options and restricted stock unit and performance unit
awards granted under the Company's 1993 and 1996 Long-Term Stock Incentive Plans
(collectively, the "PLAN") and supplements the provisions in the Plan and in the
respective Award Agreements. Capitalized terms used in this letter shall have
the same meanings as in the Plan.

Stock Options:      In the event of a Transaction, as defined below, all
                    outstanding Options then held by you shall be canceled as of
                    the date of such Transaction. For each Share underlying such
                    Option, you will be entitled to receive the excess, if any,
                    of (i) the amount or value per share to be received by the
                    Company's stockholders in connection with such Transaction
                    (the "TRANSACTION PRICE") over (ii) the exercise price for
                    such Share under the terms of the relevant Award Agreement.
                    With respect to Options that were already vested as of the
                    date of such Transaction, such amounts will be paid to you
                    in cash as soon as practicable following the Transaction.
                    With respect to Options that were not vested at the time of
                    the Transaction, such amounts shall be paid to you in cash
                    at the time such awards would otherwise have vested pursuant
                    to the terms




<PAGE>   2

                    of the respective Award Agreements, as long as you remain
                    continuously employed by the Company until such payment
                    date, except as described below.

Restricted Stock    In the event of a Transaction, all of your outstanding
Unit and            Restricted Stock Units and Performance Awards ("UNITS")
Performance         shall be canceled as of the date of such Transaction. For
Awards:             each such Unit, you shall be entitled to receive the
                    Transaction Price, which amount will be paid at the time
                    such awards would otherwise have been available for vesting
                    pursuant to the terms of the respective Award Agreements,
                    whether or not any applicable FAD targets are in fact
                    satisfied, as long as you remain continuously employed by
                    the Company until such payment date, except as described
                    below. Such amounts will bear interest from the date of the
                    Transaction to the date of payment, payable on the last day
                    of each calendar quarter, at the rate of 5% through February
                    29, 2000, and at 6% from March 1, 2000 until the date such
                    Unit would have been available for vesting or if sooner,
                    until payment for such Units is made in accordance with this
                    agreement. Interest will be payable to you in cash as
                    promptly as practicable following each interest payment
                    date.

                    "TRANSACTION" shall mean the occurrence of any of the
                    following events:

                           (i) Any "person," as such term is used in Section

                    trustee or other fiduciary holding securities under an
                    employee benefit plan of the Company) is or becomes the
                    "beneficial owner" (as defined in Rule 13d-3 under the
                    Exchange Act), directly or indirectly, of securities of the
                    Company representing 20% or more of the combined voting
                    power of the Company's then outstanding securities;

                           (ii) During any period of two consecutive years
                    commencing on the date hereof, individuals who at the
                    beginning of such period constitute the Board, and any new
                    director (other than a director designated by a person (as

                    shareholders was approved by a vote of at least two-thirds
                    (2/3) of the directors then still in office who either were
                    directors at the beginning of the period or whose election
                    or nomination for election was previously so approved, cease
                    for any reason to constitute at least a majority thereof;

                           (iii) The shareholders of the Company have approved a
                    merger or consolidation of the Company with any other
                    company and all other required governmental approvals of
                    such merger or consolidation have been obtained, other than

                    voting securities of the Company outstanding immediately
                    prior thereto continuing to represent (either by remaining
                    outstanding or by being converted into voting securities of
                    the surviving entity) more than 60% of the combined voting
                    power of the voting securities of the Company or such

                    the beneficial owner (as defined above) or more than 20% of
                    the combined voting power of the Company's then outstanding
                    securities; or

                           (iv) the shareholders of the Company have approved a
                    plan of complete liquidation of the Company or an agreement
                    for the sale or disposition by the Company of all or
                    substantially all of the Company's assets, and all other
                    governmental approvals of such transaction have been
                    obtained.

Payment:            by the Company without Cause, as defined below, or by
                    yourself for Good Reason, as defined below, prior to the
                    date of payment of the value of outstanding unvested Options
                    and Units (as provided above), the payment of the value of
                    such awards as described herein will be made as promptly as
                    practicable, but in any event within 10 days, after the date

                    physical or mental illness or as a result of a termination
                    of employment by you for Good Reason), (ii) any willful act
                    or omission by you constituting dishonesty, fraud or other

                    of the Company or any of its affiliates, or (iii) your

                    thereof or any other jurisdiction in which the Company or
                    any of its subsidiaries conducts business. For purposes of
                    this definition, no act or failure to act shall be deemed
                    "willful" unless effected by you not in good faith and
                    without a reasonable belief that such action or failure to
                    act was in or not opposed to the best interests of the
                    Company.

                    "GOOD REASON" shall mean:

                           (ii) Material diminution in your position or
                    responsibilities, such as would amount effectively to a
                    demotion;

                           (iii) Reduction in your base salary or maximum annual
                    bonus opportunity, or breach by the Company of any of the
                    provisions of this letter agreement; or

                           (iv) Relocation of your principal workplace without
                    your consent to a location outside the general area where
                    you are currently employed.

Legal Expenses:     In the event that it becomes necessary for you to engage
                    legal counsel to pursue a legal remedy for the Company's

                    Company will reimburse you for the fees and expenses of
                    such counsel, when and as incurred by you, unless your claim
                    is determined by a court or arbitrator to be without merit.

absolute and unconditional without defense or set-off by reason of any default
by the Issuer under this Loan Agreement, or under any other agreement between
the Borrower and the Issuer, or for any other reason, it being the intention of
the parties that the payments required by this Loan Agreement will be paid in
full when due without any delay or diminution whatsoever.

        Section 2.4. Deficiencies in Revenues. If, for any reason, amounts paid
to the Trustee under the Loan, together with other moneys held by the Trustee
and then available, would not be sufficient to make payments of principal or
redemption price of, and accrued and unpaid interest, if any, on, the Bonds and
all other amounts due and owing under the Indenture when such payments are due
and payable, the Borrower will pay the amounts required to make up any such
deficiency.

        Section 2.5. Manner of Payment. The payments provided for herein shall
be paid by the Borrower in immediately available funds or by wire transfer, free
of deductions and without any abatement, recoupment, diminution or set-off
whatsoever, on the date on which such payment is due and payable, directly to
the Trustee for the account of the Issuer and shall be deposited in the Revenue
Fund, except that payments made pursuant to Sections 7.11, 8.5 and 9.3 hereof
shall be made directly to the party to whom such payment is due and owing.

        Section 2.6. Repayment of Loan. Subject to the next succeeding
paragraph, the Borrower will repay the Loan as follows: (a) by 3:00 p.m. (local
time at the Principal Office of the Trustee) one Business Day prior to each day
on which any payment of either principal or redemption price of the Bonds, or
both, shall become due and payable (whether at maturity, or upon redemption or
acceleration or otherwise), the Borrower will pay such amounts to the Trustee,
and (b) by 10:00 a.m. on the due date of interest on the Bonds, the Borrower
will pay an amount sufficient to pay accrued and unpaid interest, if any, due
and payable on the Bonds to the Trustee. It is intended that payments made under
the Loan shall be made at such time and in such amounts as shall be sufficient
to enable the Trustee to make timely payments of principal or redemption price
of, and accrued and unpaid interest, if any, on, the Bonds.

        The Borrower, at its option, may provide for the payment of the
principal of the Bonds when due (whether upon redemption or acceleration) and
premium, if any, and accrued and unpaid interest, if any, on, the Bonds,
together with the purchase price for unremarketed Bonds, by the delivery of a
Letter of Credit to the Trustee at any time that the Bonds are subject to
mandatory tender. Upon delivery of such a Letter of Credit, the Borrower hereby
authorizes and directs the Trustee to draw moneys under the Letter of Credit in
accordance with its terms.

        If the amounts available under any Letter of Credit delivered to the
Trustee are insufficient to pay the principal of the Bonds when due (whether at
maturity or upon acceleration or redemption or otherwise) or to pay premium, if
any, accrued and unpaid interest, if any, or purchase price on, the





                                       7
<PAGE>   12

Bonds when due, the Borrower shall be obligated to furnish to the Trustee a sum
equal to the difference between the amount available for such purpose and such
amount due on the Bonds.

        To the extent that any of the foregoing payments are made from the
proceeds of a drawing under a Letter of Credit, such payment amount shall be
credited to the payments due the Issuer hereunder, and the Borrower shall
reimburse the Letter of Credit Issuer any sums due it in accordance with the
Reimbursement Agreement. Any amounts in the Revenue Fund after payment of
amounts then due and payable on the Bonds shall be applied to reimburse the
Letter of Credit Issuer for any amounts drawn under the Letter of Credit.

        Section 2.7. Additional Payment Obligations of Borrower. Upon the
failure of any Letter of Credit Issuer to do so, the Borrower agrees to pay to
the Trustee amounts sufficient to pay the purchase price of any Bonds to be
purchased pursuant to Article III of the Indenture by 2:30 p.m., New York City
time, on the date such Bonds (if such Bonds accrue interest at a Daily Rate,
Weekly Rate or Term Rate) are to be purchased pursuant to said Article III or by
3:00 p.m., New York City time, on the date any Bonds accruing interest at a
Flexible Rate are to be purchased pursuant to said Article III; provided,
however, that the obligation of the Borrower to make such payment hereunder with
respect to the purchase of Bonds pursuant to Article III of the Indenture shall
be reduced by the amount of money available for such payment from the
remarketing of Bonds thereunder. All such payments shall be made to the Trustee
at its Principal Office, in lawful money (immediately available) of the United
States of America. The Borrower directs the Trustee to apply such amounts to the
purchase price of the Bonds (which have not been remarketed) so as to assure
timely payment to the Bond Owners thereof on the date due.

        The Borrower agrees to pay to the Issuer (i) an initial fee of
$442,737.50, which shall be paid on or before the Closing Date, (ii) the
Issuer's annual fee in an amount equal to .15% per annum of the original
aggregate principal amount of the Bonds, which amount shall be paid in twelve
monthly installments of $41,773.75 (pro rated for a partial month) each, in
arrears, commencing July 1, 1998, and continuing until the end of the Qualified
Project Period, which shall be paid to the Trustee for remittance to the Issuer;
provided that at any time the Bonds are rated "A" or better, the Issuer's annual
fee shall be .125% of the original principal amount of the Bonds; and provided
further that the amount of the Issuer's annual fee may be changed, upon the
request of the Borrower subsequent to any change in policies of the Issuer
relating to publicly traded real estate investment trusts (or other entities
that derive revenues from ownership of real estate assets), with the approval of
the governing board of the Issuer, it being the intention of the Issuer that the
fee paid by the Borrower be no greater than the annual fee charged by the Issuer
to other comparably rated publicly traded real estate investment trusts (or
other entities that derive revenues from ownership of real estate assets) and
(iii) within thirty (30) days after receipt of written request for payment
thereof, all reasonable out-of-pocket expenses of the Issuer (not including
salaries and wages of Issuer employees) related to the Projects and the
financing thereof that are not otherwise required to be paid by the Borrower
under the terms of this Loan Agreement and are not paid from the Cost of
Issuance Fund under the Indenture, including, without limitation, reasonable
legal fees and expenses incurred in connection with the interpretation,
performance, enforcement or amendment of any documents relating to the Projects
or the Bonds.

        Borrower also agrees to deliver to the Issuer on the Closing Date the
Issuer Letter of Credit. The Issuer may draw on the Issuer Letter of Credit at
any time in connection with, and in an amount





                                       8
<PAGE>   13

equal to, any and all actual costs and expenses incurred by the Covered Parties
(as defined below) and arising out of litigation (including counterclaims and
cross-claims) brought against any of the Covered Parties which is directly
related to the Bonds, the Projects or the Indenture; provided, however, that the
Issuer shall not have the right to draw on the Issuer Letter of Credit for costs
and expenses arising out of litigation that relates to the willful misconduct of
any of the Covered Parties. Partial and multiple drawings on the Issuer Letter
of Credit shall be permitted. In connection with any draw on the Issuer Letter
of Credit, but not as a condition to such draw, the Issuer shall deliver to
Borrower invoices or other evidence substantiating the fees, costs and expenses
for which the Issuer has drawn on the Issuer Letter of Credit. To the extent
that the litigation is resolved and the amounts drawn by Issuer on the Issuer
Letter of Credit are not applied to the actual costs and expenses incurred by
the Covered Parties as a result of such litigation, the Issuer will promptly
deliver such remaining amounts to Borrower. As used herein, "Covered Parties"
shall mean the Issuer, its Members and/or Program Participants, and their
respective officials, employees and agents.

        The Borrower may at any time replace the Issuer Letter of Credit with a
substitute Issuer Letter of Credit or, in lieu of delivering a substitute letter
of credit, deposit with the Issuer cash in the amount of $2,000,000, which cash
shall be invested as directed by the Borrower in Permitted Investments
reasonably approved by the Issuer, the earnings on which in excess of $2,000,000
shall be paid to the Borrower. The Borrower understands that it shall comply
with the terms of this Section at any and all times until termination of this
Loan Agreement, except during such times that any Rating Agency rates the Bonds
or the credit of the Borrower as "A" or better.

        Section 2.8. Conversion Right. The Borrower may elect to convert the
rate of interest borne by any Subseries of Bonds from one type of Interest Rate
to another but only in accordance with the provisions governing such conversion
set forth in the Indenture and the form of Bond contained in Section 2.3 of the
Indenture.

        Section 2.9. Nonrecourse to General Partner. Not withstanding anything
contained in this Loan Agreement to the contrary, the obligations of the
Borrower under this Loan Agreement shall be nonrecourse to the General Partner
and the real property, personal property and other assets or interests of the
General Partner. At no time will any partner of the Borrower or related person
(as defined in Treasury Regulations Section 1.752-4(b)) have any obligation to
make a payment to any person (or a contribution or other payment to the
Borrower) out of nonpartnership assets because the Loan or other obligations
under this Loan Agreement have become due and payable, whether upon the
liquidation of the Borrower or otherwise.

                                   ARTICLE III

                                      FUNDS

        Section 3.1. Application of Bond Proceeds. In order to provide funds to
make the Loan, the Issuer, concurrently with the execution and delivery of this
Loan Agreement, will issue, sell and deliver the Bonds to the Underwriters and
cause the Bond Proceeds to be delivered to or for the account of the Trustee as
provided in the Redemption Agreement, to be applied to the current refunding of
the Prior Bonds.

<PAGE>   14

        Section 3.2. Borrower Required to Pay if Refunding Fund Insufficient. In
the event the moneys in the Refunding Fund are not sufficient to pay all costs
(including interest, fees and expenses) of refunding the Prior Bonds in full,
the Borrower agrees to pay that portion of the costs in excess of the moneys
available therefor in the Refunding Fund. The Issuer and the Trustee make no
warranty, either express or implied, that the moneys paid into the Refunding
Fund and available for payment of the costs of refunding the Prior Bonds will be
sufficient to pay all of such costs. The Borrower agrees that if, after
disbursement of all the money in the Refunding Fund available for payment of
costs of refunding the Prior Bonds, the Borrower should pay any portion of the
costs of refunding the Prior Bonds pursuant to the provisions of this Section,
it shall not be entitled to any reimbursement therefor from the Issuer or the
Trustee.

        Section 3.3. Rebate Fund. The Indenture requires the Trustee to deposit
all moneys paid by the Borrower pursuant to Section 7.5 hereof in the Rebate
Fund. Investment earnings on all amounts so deposited in the Rebate Fund shall
also be deposited in the Rebate Fund immediately upon receipt.

        The Indenture provides that the Trustee shall make payments from the
Rebate Fund to the United States on behalf of the Issuer upon the written
direction of the Borrower in accordance with Section 7.5 hereof. The Borrower
hereby confirms its covenant in Section 7.5 hereof to give the Trustee all such
required written directions.

        Section 3.4. Investment of the Funds. Any moneys held as a part of the
Funds shall be invested and reinvested by the Trustee in Permitted Investments,
in accordance with Section 5.5 of the Indenture. The Trustee may make any and
all such Permitted Investments through its own investment department.

        The Borrower shall direct investments of amounts in the Funds so that
such Permitted Investments shall mature in such amounts and at such times, or
shall be redeemable by the Trustee at such times, as may be necessary to provide
funds when, at the time of the investment, it is anticipated the same will be
needed to make payments from the Funds in accordance with the provisions of
Section 5.5 of the Indenture. To the extent required for payments from the
Funds, the Trustee may, at any time, after consultation with the Borrower, sell
any of such Permitted Investments. The proceeds of any such sale, all payments
at maturity and all payments upon redemption of such Permitted Investments shall
be held in the respective Funds in which such investment income was derived.

        The Borrower shall be entitled to receive from the Trustee annually and
at such other times as the Borrower may reasonably request, a statement of
account of any moneys held in the Funds by the Trustee.

and will constitute a permissible public purpose under the Act. By proper
action, the Issuer has authorized the execution, delivery and due performance of
the Issuer Documents.

               (b) Neither the execution and delivery of the Bonds, the Issuer
Documents and the Tax Certificate, nor the Issuer's compliance with the terms,
conditions or provisions on the part of the Issuer in the Bonds, the Issuer
Documents and the Tax Certificate, to the knowledge of the Issuer, conflicts in
any material respect with or results in a material breach of any of the terms,
conditions or provisions of any constitution or statute of the State, or of any

party or by which it is bound or constitutes a material default by the Issuer

provisions of the Act and the Refunding Law to be complied with by the Issuer
applicable to the Bonds and the transactions contemplated by this Loan Agreement
and the other Issuer Documents.

secured by the Indenture, pursuant to which the Issuer's interest in this Loan
Agreement (other than its Reserved Rights) is pledged and assigned to the

assign its interest in this Loan Agreement other than to the Trustee under the
Indenture.

               (f) No litigation or administrative action of any nature has been
served on the Issuer and is now pending (i) seeking to restrain or enjoin the
execution and delivery of the Bond Documents, or in any manner questioning the
proceedings or authority relating thereto or otherwise affecting the validity of
the Bonds, or (ii) as to the existence or authority of the Issuer or that of its
present or former members or officers and, to the knowledge of the Issuer, none
of the foregoing are threatened.

        The Issuer makes no representation or warranty that the Projects will be
adequate or sufficient for the purposes of the Borrower.

        Section 5.4. No Defaults. To the actual knowledge of the Borrower, the
Borrower is not in default in the performance, observance or fulfillment of any
of the obligations, covenants or conditions contained in any material agreement

the proceeds received by it from the issuance of the Bonds, the Prior Bonds and
the obligations refunded by the Prior Bonds to the financing and refinancing of
the Projects.

                            COVENANTS OF THE BORROWER

        The Borrower covenants and agrees, so long as this Loan Agreement shall
remain in effect or the Bonds shall be Outstanding, as follows:

        Section 7.1. Limitations on Incurrence of Indebtedness.

               (a) The Borrower will not, and will not permit any Subsidiary to,
incur any Indebtedness if, immediately after giving effect to the incurrence of
such additional Indebtedness and the application of the proceeds thereof, the
aggregate principal amount of all outstanding Indebtedness of the Borrower and
its Subsidiaries on a consolidated basis determined in accordance with GAAP is
greater than 60% of the sum of (without duplication) (i) the Total Assets of the
Borrower and its Subsidiaries as of the end of the most recently completed
calendar quarter of the Borrower for which financial information is available
prior to the incurrence of such additional Indebtedness and (ii) the purchase
price or cost of any real estate assets or mortgages receivable acquired or
developed, and the amount of any securities offering proceeds received (to the
extent such proceeds were not used to acquire real estate assets or mortgages
receivable, to develop real estate assets or to reduce Indebtedness), by the
Borrower or any Subsidiary since the end of such calendar quarter, including
those proceeds obtained in connection with the incurrence of such additional
Indebtedness.

               (b) The Borrower will not, and will not permit any Subsidiary to,
incur any Indebtedness secured by any Encumbrance upon any of the property of
the Borrower or any Subsidiary if, immediately after giving effect to the
incurrence of such additional Indebtedness and the application of the proceeds
thereof, the aggregate principal amount of all outstanding Indebtedness of the
Borrower and its Subsidiaries on a consolidated basis which is secured by any
Encumbrance on property of the Borrower or any Subsidiary is greater than 40% of
the sum of (without duplication) (i) the Total Assets of the Borrower and its
Subsidiaries as of the end of the most recently completed calendar quarter of
the Borrower for which financial information is available prior to the
incurrence of such additional Indebtedness and (ii) the purchase price or cost
of any real estate assets or mortgages receivable acquired or developed, and the
amount of any





                                       14
<PAGE>   19

securities offering proceeds received (to the extent such proceeds were not used
to acquire real estate assets or mortgages receivable, to develop real estate
assets or to reduce Indebtedness), by the Borrower or any Subsidiary since the
end of such calendar quarter, including those proceeds obtained in connection
with the incurrence of such additional Indebtedness.

               (c) The Borrower and its Subsidiaries may not at any time own
Total Unencumbered Assets equal to less than 150% of the aggregate outstanding
principal amount of the Unsecured Indebtedness of the Borrower and its
Subsidiaries on a consolidated basis.

               (d) The Borrower will not, and will not permit any Subsidiary to,
incur any Indebtedness if the ratio of Consolidated Income Available for Debt
Service to the Annual Service Charge for the four consecutive fiscal quarters
most recently ended prior to the date on which such additional Indebtedness is
to be incurred shall have been less than 1.5:1, on a pro forma basis after
giving effect thereto and to the application of the proceeds therefrom, and
calculated on the assumption that (i) such Indebtedness and any other
Indebtedness incurred by the Borrower and its Subsidiaries since the first day
of such four-quarter period and the application of the proceeds therefrom,
including to refinance other Indebtedness, had occurred at the beginning of such
period; (ii) the repayment or retirement of any other Indebtedness by the
Borrower and its Subsidiaries since the first day of such four-quarter period
had been repaid or retired at the beginning of such period (except that, in
making such computation, the amount of Indebtedness under any revolving credit
facility shall be computed based upon the average daily balance of such
Indebtedness during such period); (iii) in the case of Acquired Indebtedness or
Indebtedness incurred in connection with any acquisition since the first day of
such four-quarter period, the related acquisition had occurred as of the first
day of such period with the appropriate adjustments with respect to such
acquisition being included in such pro forma calculation; (iv) in the case of
any acquisition or disposition by the Borrower or its Subsidiaries of any asset
or group of assets since the first day of such four-quarter period, whether by
merger, stock purchase or sale, or asset purchase or sale, such acquisition or
disposition or any related repayment of Indebtedness had occurred as of the
first day of such period with the appropriate adjustments with respect to such
acquisition or disposition being included in such pro forma calculation; and (v)
Consolidated Interest Expense attributable to any Indebtedness (whether existing
or being incurred) computed on a pro forma basis and bearing a floating interest
rate shall be computed as if the rate in effect on the date of computation
(taking into account if such Person or any of its Subsidiaries is a party to an
interest rate agreement or other interest protection agreement applicable to
such floating rate Indebtedness if such agreement shall remain in effect for the
twelve month period after the date of the transaction giving rise to the need to
calculate the ratio of Consolidated Income Available for Debt Service to Annual
Service Charge) had been the applicable rate for the entire period.

               (e) For purposes of determining any particular amount of
Indebtedness under this Section 7.1, guarantees of, liens securing, or letters
of credit that support, in each case, Indebtedness otherwise included in the
determination of such particular amount of Indebtedness, shall not be included.
In addition, the amount of Indebtedness issued at a price that is less than the

        Section 7.3. [Reserved]

        Section 7.4. [Reserved]

        Section 7.5. Compliance with Code and Regulations.

               (a) The Borrower shall at all times do and perform all acts and
things necessary in order to assure that interest paid on the Bonds shall, for
the purposes of federal income taxation, be excludable from the gross income of
the recipients thereof, except in the event that such recipient is a Substantial
User or Related Person to a Substantial User.

               In addition, any and all actions to be undertaken by the Borrower
or by any other Person as to which the Issuer must, pursuant to the terms
hereof, consent or approve in advance, shall be deemed to be the actions of the
Borrower or such other Person (and not the actions of the Issuer).

               (b) The Borrower shall not permit at any time or times any of the
Gross Proceeds to be used, directly or indirectly, to acquire any Investment
Property (within the meaning of Section 148(b)(2) of the Code) the acquisition
of which would cause the Bonds to be "arbitrage bonds" for the purposes of
Section 148 of the Code.

               (c) The Borrower shall use the Bond Proceeds to refund the Prior
Bonds. The proceeds of the Prior Bonds were used to refinance the Projects in
the manner and as specifically set forth in the Tax Certificate, the terms of
which are hereby incorporated herein in their entirety. The Borrower has not
expended the Bond Proceeds on assets other than those described in the Tax
Certificate.

               (d) The Borrower shall calculate or cause to be calculated
Rebatable Arbitrage (as defined in Section 5.9 of the Indenture) in accordance
with the provisions of Section 5.9 of the Indenture and the Tax Certificate and
shall pay to the Trustee the amount of any Rebatable Arbitrage for deposit to
the Rebate Fund. The Borrower shall direct the Trustee in writing to pay to the
United States any Rebatable Arbitrage as required by Section 5.9 of the
Indenture and the Tax Certificate.

        Section 7.6. [Reserved]

        Section 7.7. Financial Statements. The Borrower agrees that it will
deliver to the Issuer and the Trustee, as soon as practicable, and in any event
within one hundred twenty (120) days after the end of each fiscal year of the
Borrower, the audited financial statements of the Borrower. In satisfaction of
the requirements of this Section 7.7, the Borrower may make available its Annual
Report on Form 10-K (including materials incorporated therein by reference), as
filed by the Borrower with the Securities and Exchange Commission either by
delivery of a copy thereof or by an incorporation by reference of such Annual
Report on Form 10-K from materials on file with the Securities and Exchange
Commission.

        Section 7.8. Mergers, etc. The Borrower shall maintain its existence as
a legal entity and shall not sell, assign, transfer or otherwise dispose of
substantially all of its assets, except for any disposition as may be required
by a condemnation by a proper authority. Notwithstanding the preceding sentence,
the Borrower may merge with or into or consolidate with another entity, and the





                                       16
<PAGE>   21

Projects or this Loan Agreement may be transferred without violating this
Section; provided (1) the Borrower provides to the Issuer notice of the proposed
surviving, resulting or transferee entity on or before the effective date of
such merger or consolidation; (2) either the Borrower shall be the continuing
entity, or the successor entity or the Person which acquires by sale or
conveyance any or all the assets of the Borrower (if other than the Borrower)
shall be an entity organized under the laws of the United States of America or
any State thereof and shall expressly assume the applicable obligations of the
Borrower under the Loan and this Loan Agreement; (3) after giving effect to such
merger or consolidation, or such sale or conveyance, no Event of Default, and no
event which, after notice or lapse of time, or both, would become an Event of
Default, shall have occurred and be continuing; and (4) the written consent of
the Letter of Credit Issuer (if any) is delivered to the Issuer and the Trustee.
In the event of any such sale or conveyance (other than a conveyance by way of
lease) and upon any such assumption by a successor entity, the Borrower or any
successor entity which shall theretofore have become such in the manner
described in this Section 7.8 shall be discharged from all applicable
obligations and covenants under this Loan Agreement.

        The Borrower shall, prior to the taking of any of the foregoing proposed
actions, deliver to the Issuer and the Trustee a Favorable Opinion of Bond
Counsel.

        Section 7.9. Assignment of Loan Agreement. Subject to the provisions of
Section 7.8, the Borrower may not assign or transfer the whole or any part of
this Loan Agreement without the prior express written consent of the Issuer and
the Trustee. Any assignment of this Loan Agreement by the Borrower without the
prior express written consent of the Issuer and the Trustee shall be null and
void.

        Section 7.10. [Reserved]

        Section 7.11. Indemnification. To the fullest extent permitted by law,
the Borrower agrees to indemnify, hold harmless and defend the Issuer, the
Trustee and the Tender Agent, and each of their respective officers, governing
members, directors, officials, employees, attorneys and agents, and, with
respect to the Issuer, the applicable program participant (collectively, the
"Indemnified Parties"), against any and all actual losses, damages, claims,
actions, liabilities, costs and expenses of any conceivable nature, kind or
character (including, without limitation, reasonable attorneys' fees, litigation
and court costs, amounts paid in settlement and amounts paid to discharge
judgments) to which the Indemnified Parties, or any of them, may become subject
under federal or state securities laws or any other statutory law or at common
law or otherwise, arising out of or based upon or in any way relating to:

               (a) the Issuer Documents or the execution or amendment thereof or
in connection with transactions contemplated thereby, including the issuance,
sale, resale or remarketing of the Bonds;

               (b) any act or omission of the Borrower or any of its agents,
contractors, servants, employees or licensees in connection with the Loan or the
Projects, the operation of the Projects, or the condition, environmental or
otherwise, occupancy, use, possession, conduct or management of work done in or
about, or from the planning, design, acquisition, installation or construction
of, any Project or any part thereof;





                                       17
<PAGE>   22

               (c) any lien or charge upon payments by the Borrower to the
Issuer and the Trustee hereunder, or any taxes (including, without limitation,
all ad valorem taxes and sales taxes), assessments, impositions and other
charges imposed on the Issuer or the Trustee in respect of any portion of any
Project;

               (d) any violation of any environmental law, rule or regulation
with respect to, or the release of any toxic substance from, any Project or any
part thereof;

               (e) the defeasance and/or redemption, in whole or in part, of the
Bonds;

               (f) any untrue statement or misleading statement or alleged
untrue statement or alleged misleading statement of a material fact by the
Borrower contained in any offering statement or document for the Bonds or any of
the documents relating to the Bonds to which the Borrower is a party, or any
omission or alleged omission from any offering statement or document for the
Bonds of any material fact necessary to be stated therein in order to make the
statements made therein by the Borrower, in the light of the circumstances under
which they were made, not misleading;

               (g) the Trustee's acceptance or administration of the trust of
the Indenture, or the exercise or performance of any of its powers or duties
thereunder or under any of the documents relating to the Bonds to which it is a
party;

except (a) in the case of the foregoing indemnification of the Trustee or the
Tender Agent or any of their respective officers, members, directors, officials,
employees, attorneys and agents, to the extent such damages are caused by the
negligence or willful misconduct of such Indemnified Party; or (b) in the case
of the foregoing indemnification of the Issuer or any of its officers, members,
directors, officials, employees, attorneys and agents, to the extent such
damages are caused by the negligence or willful misconduct of such Indemnified
Party. In the event that any action or proceeding is brought against any
Indemnified Party with respect to which indemnity may be sought hereunder, the
Borrower , upon written notice from the Indemnified Party, shall assume the
investigation and defense thereof, including the employment of counsel selected
by the Indemnified Party, and shall assume the payment of all expenses related
thereto, with full power to litigate, compromise or settle the same in its sole
discretion; provided that the Indemnified Party shall have the right to review
and approve or disapprove any such compromise or settlement, which approval
shall not be unreasonably withheld or delayed. Each Indemnified Party shall have
the right to employ separate counsel in any such action or proceeding and
participate in the investigation and defense thereof, and the Borrower shall pay
the reasonable fees and expenses of such separate counsel; provided, however,
that such Indemnified Party may only employ separate counsel at the expense of
the Borrower if in its reasonable judgment a material conflict of interest
exists by reason of common representation or if all parties commonly represented
do not agree as to the action (or inaction) of counsel.

        Notwithstanding any transfer of a Project to another owner in accordance
with the provisions of this Loan Agreement, the Borrower shall remain obligated
to indemnify each Indemnified Party pursuant to this Section if such subsequent
owner fails to indemnify any party entitled to be indemnified hereunder, unless
such Indemnified Party has consented to such transfer and to the assignment of
the rights and obligations of the Borrower hereunder.





                                       18
<PAGE>   23

        The rights of any persons to indemnity hereunder and rights to payment
of fees and reimbursement of expenses pursuant to Section 2.7 hereof shall
survive the final payment or defeasance of the Bonds and in the case of the
Trustee any resignation or removal. The provisions of this Section shall survive
the termination of this Loan Agreement.

        The foregoing provisions shall not provide the Bond Owners with any
rights against the Borrower, in addition to those contained in the Bonds, if
any, upon a determination that interest on the Bonds has become taxable for
federal income tax purposes, provided the Borrower acts in accordance with the
redemption provisions of the Bonds.

        Section 7.12. [Reserved].

Representative of the Borrower to the effect that it is not aware of any
condition, event or act which constitutes an Event of Default under this Loan
Agreement or of any condition, event or act which, with notice or lapse of time,
or both, would constitute an Event of Default, or if any such condition, event
or act exists, specifying the same.

               (b) The Borrower further agrees to notify the Trustee in writing
of any occurrence of an Event of Default of which the Borrower has actual
knowledge or any condition, event or act of which the Borrower has actual
knowledge which, with notice or lapse of time, or both, would constitute an
Event of Default of which the Borrower has actual knowledge and the action which
the Borrower proposes to take with respect thereto; the notification shall be
given by the Borrower as soon as practicable but in any event not later than ten
(10) Business Days after the event giving rise to the requirement of
notification.

Borrower for any brokerage fee, finders fee, or loan servicing fee and the
Borrower shall hold the Issuer harmless from any such fees or claims.

        Section 7.16. Covenant by Borrower as to Compliance with Indenture. The
Borrower covenants and agrees that it will not knowingly interfere with the
exercise of the power and authority granted to the Trustee in the Indenture. The
Borrower further agrees to aid in furnishing to the Issuer or the Trustee any
documents, certificates or opinions that may be required under the Indenture and
to comply with the provisions thereof to the extent applicable to the Borrower.

        Section 7.17. Letter of Credit. If at any time the Borrower elects to
obtain a Letter of Credit with respect to any Subseries of Bonds or an Alternate
Letter of Credit, the Borrower may submit such Letter of Credit to a Rating
Agency for the purposes of obtaining a rating on the Bonds. The Borrower shall
furnish the Trustee with the original of any Letter of Credit or Alternate
Letter of Credit obtained pursuant to this Section, and, if such Letter of
Credit is submitted to a Rating Agency, evidence of any rating or ratings
obtained on the Bonds in connection therewith. No Alternate Letter of Credit may
replace a Letter of Credit unless all amounts owed to such Letter of Credit
Issuer in respect of Pledged Bonds and under the Reimbursement Agreement have
been paid.

                              DEFAULTS AND REMEDIES

        Section 8.1. Events of Default. Any one or more of the following events
shall constitute an Event of Default hereunder:

               (a) if any representation or warranty made herein or in any other
Loan Document or in any report, certificate, financial statement or other
instrument furnished in connection with this Loan Agreement shall prove to be
false or misleading in any material respect when made;

               (b) default in the payment of any installment of the principal
of, prepayment premium, if any, or accrued and unpaid interest, if any, under
the Loan on the dates when due;

               (c) default in the due observance or performance of any material
covenant, condition or agreement on the part of the Borrower to be observed or
performed pursuant to the terms of the Loan Documents, other than the payment of
principal and interest which shall be governed by (b) above, and such default
shall continue unremedied for thirty (30) days after Borrower's receipt of
written notice thereof given by the Issuer or the Trustee (with a copy to the
other), any such notice to specify the default, require it to be remedied and to
state that such notice is a "Notice of Default" hereunder; provided, however, if
such default is incapable of being remedied within such thirty (30) day period
and the Borrower is making reasonable efforts to remedy such default, the
Borrower shall have ninety (90) days after written notice given as aforesaid to
cure such default; or

               (d) the occurrence of an Act of Bankruptcy.

        Section 8.2. Remedies. Whenever any Event of Default referred to in
Section 8.1 hereof shall have occurred and be continuing, provided that written
notice of the Event of Default, when required, has been given to the Borrower by
the Issuer (or the Trustee) and the Event of Default has not theretofore been
cured within the applicable cure period, and provided, further, that no remedial
steps shall be taken by the Issuer the effect of which would be to entitle the
Issuer to funds necessary for the payment of principal of and accrued and unpaid
interest, if any, on the Bonds which have not yet matured unless such principal
and interest shall have been declared due and payable in accordance with the
Indenture and such declaration shall not have been rescinded, the Issuer may
take any one or more of the following remedial steps:

               (a) declare the principal of and accrued and unpaid interest, if
any, on the Loan due and payable; and

               (b) the Issuer may take any action at law or in equity to collect
the payments then due and thereafter to become due or to enforce performance and
observance of any obligation, agreement or covenant of the Borrower under this
Loan Agreement.

        Any amounts collected pursuant to action taken under this Section 8.2
shall be applied in accordance with the Indenture.

        Section 8.3. No Remedy Exclusive. No remedy herein conferred or reserved
to the Issuer is intended to be exclusive of any other available remedy or
remedies, but each and every such remedy shall be cumulative and shall be in
addition to every other remedy given under this Loan Agreement or now or
hereafter existing at law or in equity or by statute. No delay or omission to
exercise any right or power accruing upon any Event of Default shall impair any
such right or power or shall be construed to be a waiver thereof, but any such
right and power may be exercised from time to time and as often as may be deemed
expedient. In order to entitle the Issuer to exercise any remedy reserved to it
in this Article, it shall not be necessary to give notice, other than such
notice as may be required in this Article.

        Section 8.4. Additional Remedies. In addition to the above remedies, if
the Borrower commits a breach or threatens to commit a breach of this Loan
Agreement, the Issuer shall have the right and remedy, without posting bond or
other security, to have the provisions of this Loan Agreement specifically
enforced by any court having equity jurisdiction, it being acknowledged and
agreed that any such breach or threatened breach will cause irreparable injury
to the Issuer and that money damages will not provide an adequate remedy
therefor.

        Section 8.5. Agreement to Pay Attorneys' Fees and Expenses. In the event
the Borrower should default under any of the provisions of this Loan Agreement
or the other Loan Documents and either the Issuer or the Trustee shall require
and employ attorneys or incur other expenses for the collection of payments due
or to become due or for the enforcement or performance or observance of any
obligation or agreement on the part of the Borrower or enforcement of the Bonds
under any Loan Document, the Borrower agrees that it will, on demand therefor,
pay to the Issuer or the Trustee, as the case may be, the reasonable fees of
such attorneys and such other reasonable out-of-pocket expenses so incurred by
the Issuer or the Trustee.

        Section 8.6. No Additional Waiver Implied by One Waiver. In the event
any agreement contained in any Loan Document should be breached by any party and
thereafter such breach should be waived by any party, such waiver shall be
limited to the particular breach so waived and shall not be deemed to waive any
other breach hereunder.

any other further notice or demand in the same circumstances. Any amendment of
this Loan Agreement shall be effected only in the manner provided in Article X
of the Indenture.

        Section 9.6. Failure to Exercise Rights. Neither any failure nor any
delay on the part of the Issuer in exercising any right, power or privilege

indebtedness or liability at any time owing to the Borrower by the Issuer.

by the Remarketing Agent, such Subseries shall accrue interest at a rate equal
to the rate derived from the TBMA Municipal Swap Index furnished to the Trustee
in writing by the Remarketing Agent;

                     (B) The Interest Rate then in effect for Bonds of a
Subseries that accrue interest at a Weekly Rate will remain a Weekly Rate, and
until a new Weekly Rate is determined, and furnished to the Trustee in writing,
by the Remarketing Agent, such Subseries shall accrue interest at a rate equal
to the rate derived from the TBMA Municipal Swap Index furnished to the Trustee
in writing by the Remarketing Agent;

                     (C) The Interest Rate for any Bond of a Subseries that
accrues interest at a Flexible Rate and for which a Flexible Rate and Flexible
Rate Period is not determined shall be equal to the rate derived from the TBMA
Municipal Swap Index and furnished to the Trustee in writing by the Remarketing
Agent, and the Flexible Rate Period for such Bond of a Subseries shall begin on
each Business Day and extend through the day preceding the next Business Day
until a new Flexible Rate and Flexible Rate Period is determined for such Bond
of such Subseries, and furnished to the Trustee in writing, by the Remarketing

                     (D) The Interest Rate then in effect for Bonds of a
Subseries that accrue interest at a Term Rate shall be converted automatically
to Flexible Rates determined in accordance with clause (C) above with Flexible
Rate Periods beginning on each Business Day and extending through the day

any Rate Period shall be available to Bond Owners between 1:00 p.m. and 5:00

<PAGE>   19

Letter of Credit provides less than 284 days' interest coverage, such Flexible
Rate Period shall not be longer than a period equal to the maximum number of
days' interest coverage provided by such Letter of Credit minus 14 days. Any
Bond of a Subseries may accrue interest at a Flexible Rate for a Flexible Rate
Period different from any other Bond of such Subseries. Each Flexible Rate
Period shall commence on a Business Day and end on a day immediately preceding a

for the Bonds of a Subseries for such Flexible Rate Periods and at such Flexible
Rates as it deems advisable in order to minimize the net interest cost on such
Bonds of such Subseries, taking into account prevailing market conditions;
provided, however, that the foregoing shall not prohibit the Remarketing Agent
from accepting purchase commitments for longer Flexible Rate Periods (and at

prevailing market conditions, a lower net interest cost on such Bonds can be
achieved over the longer Flexible Rate Period.

determined not later than 1:00 p.m., New York City time, on the first Business

extend to, but not include, the next succeeding Business Day.

                (ii) The Daily Rate for each Daily Rate Period shall be

until the Weekly Rate Period is converted to another type of Interest Rate;
provided that (A) in the case of a conversion to a Weekly Rate Period from
another type of Interest Rate, the Weekly Rate Period shall commence on the
Weekly Rate Conversion Date and shall end on the day prior to the commencement

Interest Rate, the last Weekly Rate Period prior to conversion shall end on the
last day immediately preceding the Conversion Date to the new type of Interest
Rate.

                (ii) The Weekly Rate for each Weekly Rate Period shall be
effective from and including the commencement date of such Weekly Rate Period
and shall remain in effect through and including the last day thereof. Each such
Weekly Rate shall be determined not later than 10:00 a.m., New York City time,
on the first day of the Weekly Rate Period to which it relates with notice
thereof provided to the Trustee by the Remarketing Agent by written, telephonic
(promptly confirmed in writing or electronically) or electronic notice by 12:00
Noon, New York City time, on such first day.

            (e) Term Rates. A Term Rate shall be determined for each Term Rate
Period, after the initial Term Rate Periods, as follows:

interest at the Term Rate may have a Term Rate Period different from a Term Rate
Period for any other Subseries.

                (ii) The Term Rate for each Term Rate Period shall be effective

electronic notice by the close of business on such Business Day.

        (C) Conversions Between Interest Rates . The Borrower may elect to

one Term Rate Period to a Term Rate Period of a different duration) as follows:

interest may be made by the Trustee by wire transfer to an account with a
financial institution in the continental United States of an Owner of $1,000,000
or more in aggregate principal amount of Bonds upon such Owner providing the
Trustee with written wire transfer instructions before the applicable Record
Date. Such interest shall be paid notwithstanding the cancellation of any Bonds
upon any exchange or registration of transfer thereof subsequent to the Record
Date and prior to such Interest Payment Date, except that, if and to the extent
there shall be a default in the payment of the interest due on such Interest
Payment Date, such defaulted interest shall be paid to the Bond Owners in whose
names such Bonds (or any Bond or Bonds issued upon registration of transfer or
exchange thereof) are registered at the close of business on the Business Day
next preceding the date of payment of such defaulted interest. Payment of
principal or purchase price of, premium, if any, and interest on, the Bonds
shall be made in such lawful money of the United States of America as, at the
respective times of payment, shall be





                                       17

legal tender for the payment of public and private debts. If a Letter of Credit
is in effect for a Subseries, and the Letter of Credit so provides, the Trustee
shall draw under the Letter of Credit in accordance with its terms to the extent
necessary to pay the principal of, premium, if any, purchase price and interest
on, such Subseries, as and when due.

        (H) Dating. The Bonds shall be dated and initially bear interest from
the Dated Date, and thereafter shall bear interest from the Interest Payment
Date next preceding the date of authentication, unless (i) authenticated prior
to the first Interest Payment Date, in which event such Bonds shall bear
interest from the Dated Date, (ii) authenticated on an Interest Payment Date, in
which event such Bonds shall bear interest from the date of authentication, or
(iii) authenticated after a Record Date and before the following Interest
Payment Date, in which event such Bonds shall bear interest from the following
Interest Payment Date. If, as shown by the records of the Trustee, interest on
the Bonds is in default, Bonds issued in exchange for Bonds surrendered for
registration of transfer or exchange shall bear interest from the date to which
interest has been paid in full on the Bonds, or, if no interest has been paid on
the Bonds, from the Dated Date. The Bonds shall also bear a date of
authentication.

        Section 2.3. Form of Bond. Subject to the provisions hereof with respect
to special endorsement of Bonds in connection with a conversion, the Bonds, the
certificate of authentication, the registration information form and the form of
assignment shall be in substantially the form hereinafter set forth, with such
appropriate variations, omissions, substitutions and insertions as are permitted
or required hereby, and may have such letters, numbers or other marks of
identification and such legends and endorsements placed thereon as may be
required to comply with any applicable laws or rules or regulations, or as may,
consistently herewith, be determined by the officers executing such Bonds, as
evidenced by their execution of the Bonds. In the preparation of definitive
forms of Bonds relative to the periods before and after a Conversion Date,
pertinent provisions of the form of Bond may be omitted, as appropriate.

        THIS BOND IS SUBJECT TO MANDATORY TENDER FOR PURCHASE AT THE TIMES AND
IN THE MANNER HEREINAFTER DESCRIBED, AND MUST BE SO TENDERED OR WILL BE DEEMED
TO HAVE BEEN SO TENDERED UNDER CERTAIN CIRCUMSTANCES AS DESCRIBED HEREIN.

        WHILE IN A DAILY RATE PERIOD OR A WEEKLY RATE PERIOD, THIS BOND SHALL BE
PURCHASED ON THE DEMAND OF THE OWNER AT THE TIMES AND IN THE MANNER HEREINAFTER
DESCRIBED.

        The CALIFORNIA STATEWIDE COMMUNITIES DEVELOPMENT AUTHORITY (the
"Issuer"), a joint powers agency of the State of California (the "State"),
hereby promises to pay to the Registered Owner specified above, or registered
assigns, the Principal Amount specified above on the Maturity Date specified
above (or earlier as hereinafter provided), and to pay interest on the Principal
Amount hereof from the Dated Date specified above at the rates per annum and on
the





                                       19
<PAGE>   25

dates set forth herein; provided, however, that such principal and interest are
payable solely from the sources and in the manner hereinafter described.

        The Bonds are issued pursuant to and in compliance with the laws of the
State, particularly Article 11 of Chapter 3 of Part 1 of Division 2 of Title 5
of the Government Code of the State (the "Refunding Law"). The Bonds are limited
obligations of the Issuer payable solely from revenues and funds pledged
therefor under the Indenture. No holder of this Bond shall ever have the right
to compel the exercise of the taxing power of the State or any political
subdivision thereof to pay the principal of this Bond or the interest hereon or
any other cost incident hereto, or to enforce payment hereof against any
property of said State or any political subdivision thereof.

        The principal of, premium, if any, and interest on, this Bond are
payable in lawful money of the United States of America. The principal and
premium, if any, payable upon maturity or earlier redemption of this Bond (and
interest on this Bond if it is accruing interest at a Flexible Rate) is payable
when due upon the presentation and surrender hereof at the principal corporate
trust office of U.S. Bank Trust National Association, as trustee (the
"Trustee"), or any successor. Each payment of interest on this Bond shall be
payable to the holder hereof as shown on the Registration Books at the close of
business on the Business Day next preceding the date on which (but, during a
Term Rate Period, the first day of the calendar month in which) such interest
becomes due and payable (herein, a "Record Date"). Interest on this Bond shall
be payable to the holder hereof by check mailed by first class mail on the
respective Interest Payment Dates (as hereinafter defined) to the address of
such holder as shown on the Registration Books at the close of business on the
relevant Record Date, or to such other address as is furnished to the Trustee
(in form satisfactory to the Trustee) by such holder prior to such Record Date.
Holders of $1,000,000 in aggregate principal amount of Bonds shall be entitled
to receive interest payments by wire transfer to an account with a financial
institution in the continental United States by providing written wire
instructions to the Trustee before the Record Date.

        This Bond is one of a duly authorized series (the "Bonds"), limited in
aggregate principal amount to $334,190,000, issued under and pursuant to
authority conferred by the Refunding Law, a Resolution of the Issuer adopted on
May 12, 1998 and the Indenture of Trust, dated as of May 15, 1998 (the
"Indenture") by and between the Issuer and the Trustee, to accomplish the public
purposes of the Refunding Law by providing financing to Irvine Apartment
Communities, L.P., a Delaware limited partnership (the "Borrower"), to refinance
existing loans with respect to certain multifamily housing projects owned by the
Borrower (the "Projects").

        The Bonds are special, limited obligations of the Issuer, payable solely
from payments made by the Borrower pursuant to the Loan Agreement dated as of
May 15, 1998 (the "Loan Agreement") by and between the Issuer and the Borrower,
from payments made pursuant to a Letter of Credit ((as hereinafter defined), if
any, and from any other moneys held by the Trustee under the Indenture for such
purpose, and other than as provided in the Loan Agreement and the Indenture,
there shall be no other recourse against the Issuer. Except as otherwise
specified in the Indenture, this Bond is entitled to the benefits of the
Indenture equally and ratably both as to principal, premium, if any, and
interest with all other Bonds issued under the Indenture, to which reference is
made for a description of the rights of the holders of the Bonds, the rights and
obligations of the Issuer, the rights, duties and obligations of the Trustee,
and the provisions relating to amendments to and modifications of the Indenture.
The holder of this Bond may not enforce the provisions of the Loan Agreement
except in





                                       20
<PAGE>   26

accordance with the provisions of the Indenture. Copies of the Indenture and the
Loan Agreement are on file at the principal corporate trust office of the
Trustee.

        This Bond has been issued in global form, registered in the name of Cede
& Co., nominee of The Depository Trust Company ("DTC"). Beneficial owners hereof
will hold their interests herein through the facilities and subject to the
procedures of DTC. By acceptance of a confirmation of purchase, delivery or
transfer, the beneficial owners of this Bond shall be deemed to have agreed to
this arrangement. Cede & Co., as registered owner of this Bond, shall be treated
as the owner hereof for all purposes.

        Reference is made to: (a) the Indenture and the Loan Agreement for
provisions concerning, as applicable, the rights of the holders and the rights
and obligations of the Issuer, the Borrower and the Trustee; and (b) the
Remarketing Agreement pursuant to which _______________________, New York, New
York, shall serve as remarketing agent for the purposes set forth in the
Indenture (such agent or its successors being herein referred to as the
"Remarketing Agent"). The acceptance of the terms and conditions of the
foregoing documents (including amplifications and qualifications of the
provisions of this Bond), each of which is on file at the principal corporate
trust office of the Trustee, is an explicit and material part of the
consideration of the Issuer's issuance of this Bond, and each holder hereof by
acceptance of this Bond accepts and assents to all such terms and conditions as
if fully set forth herein.

        Capitalized terms used in this Bond which are not defined herein but
which are defined in the Indenture shall have the respective meanings set forth
in the Indenture.

                                INTEREST ON BONDS

        The Bonds shall accrue interest at the Term Rate until changed by the
Borrower on any date on which the Bonds are subject to optional redemption in
accordance with the provisions of the Indenture or at the end of the Term Rate
Period, and will be subject to conversion as herein provided. All computations
of interest shall be computed on the basis of 360-day years of twelve 30-day
months; except for interest at Daily, Weekly or Flexible Rates, which shall be
based on 365- or 366- day years for the actual number of days elapsed.
Notwithstanding any provision of this Bond or the Indenture to the contrary, in
no event shall the cumulative amount of interest paid or payable on this Bond
(including interest calculated as provided herein, together with all other
amounts that constitute interest on this Bond under the laws of the State which
are contracted for, charged, reserved, taken or received pursuant to the Loan
Agreement or the Indenture) through any date of payment of interest or through
the date of payment of this Bond (whether at maturity, by acceleration or upon
earlier redemption) exceed the maximum rate permitted by State law.

        The Bonds may accrue interest at various types of Interest Rates
effective for Rate Periods determined as described in the Indenture. Each
Subseries of Bonds may accrue interest at a type of Interest Rate that is
different from any other Subseries. The Interest Rates for the Bonds, which will
be determined by the Remarketing Agent, are as follows:

Flexible Rate.

        While the Bonds accrue interest at Flexible Rates, the rate of interest
for each particular Bond will be determined by the Remarketing Agent and will
remain in effect from and including the





                                       21
<PAGE>   27

commencement date of the Flexible Rate Period selected for that Bond by the
Remarketing Agent to, but not including, the last date thereof. While the Bonds
accrue interest at Flexible Rates, Bonds may have successive Flexible Rate
Periods of any duration up to 270 days each (or such lower maximum number as is
then permitted under the Indenture) and any Bond may accrue interest at a rate
and for a period different from any other Bond.

Daily Rate.

        While the Bonds accrue interest at a Daily Rate, the interest rate
established for the Bonds will be effective from day to day until changed by the
Remarketing Agent.

Weekly Rate.

        While the Bonds accrue interest at a Weekly Rate, the rate of interest
on the Bonds will be determined weekly by the Remarketing Agent to be effective
for a period commencing on Wednesday (or, if such Wednesday is not a Business
Day, the next succeeding Business Day) of the week of such determination and
ending on the day prior to the commencement of the next succeeding period. (The
length of the period, the day of commencement and the last day of the period may
vary in the event of a conversion to or from a Weekly Rate.)

Term Rate.

        While the Bonds accrue interest at a Term Rate, the interest rate will
be determined by the Remarketing Agent to remain in effect for a term of at
least one year selected by the Borrower.

        The Interest Rate established will remain in effect until changed by the
Borrower, in accordance with the Indenture. During each period that a particular
type of Interest Rate is in effect, the rate of interest on the Bonds shall be
that rate which, in the judgment of the Remarketing Agent, would cause the Bonds
to have a market value as of the date of determination equal to the principal
amount thereof, taking into account prevailing market conditions, and with
respect to Flexible Rates, the Remarketing Agent shall determine the Flexible
Rate and the Flexible Rate Period for each Bond at such rate and for such period
as it deems advisable in order to minimize the net interest cost on the Bonds,
taking into account prevailing market conditions.

        Bonds which accrue interest at Flexible Rates will be issued in
denominations of $100,000 or any integral multiple of $1,000 in excess thereof.
Bonds which accrue interest at Daily Rates or Weekly Rates will be issued in
denominations of $100,000 or any integral multiple thereof (except that one Bond
may be in a denomination that is an integral multiple of $5,000 in excess of
$100,000). Bonds which accrue interest at Term Rates will be issued in
denominations of $5,000 or any integral multiple thereof.

                                OPTIONAL TENDERS

        While this Bond accrues interest at a Daily Rate or a Weekly Rate, the
Registered Owner of this Bond has the right to tender this Bond for purchase at
the principal amount hereof plus accrued interest as follows: (i) during a Daily
Rate Period, on any Business Day upon written, electronic or telephone notice to
the Tender Agent prior to 11:00 a.m., New York City time, on such Business Day
or (ii) during a Weekly Rate Period, on any Business Day upon written or
electronic notice to





                                       22
<PAGE>   28

the Tender Agent prior to 5:00 p.m., New York City time, on any Business Day at
least seven days prior to such Business Day of tender.

                         MANDATORY TENDER OR CONVERSION

        While this Bond accrues interest at a Flexible Rate, this Bond is
subject to mandatory tender on the day after the last day of each Flexible Rate
Period applicable to this Bond. While this Bond accrues interest at a Daily Rate
or a Weekly Rate, this Bond is subject to mandatory tender on the effective date
of a change from one type of Interest Rate to a different type of Interest Rate
(except for changes from a Daily Rate to a Weekly Rate or from a Weekly Rate to
a Daily Rate) or of a change from a Term Rate Period to a Term Rate Period of a
different duration. While this Bond accrues interest at a Term Rate, this Bond
is subject to mandatory tender on the last day of the Term Rate Period at a
price equal to 100% of the principal amount thereof plus accrued interest to the
mandatory tender date. While this Bond accrues interest at a Term Rate, at the
option of the Borrower, the interest rate on this Bond may be converted to a
different interest rate on any date that this Bond is also subject to optional
redemption at a purchase price equal to the principal amount hereof plus accrued
interest to the Conversion Date and plus any premium that would be payable if
such Bonds were redeemed on such date.

        Interest on any Bond which is not tendered on the mandatory tender date
or Conversion Date, but for which there has been irrevocably deposited with the
Trustee an amount sufficient to pay the purchase price thereof (an "Undelivered
Bond"), shall cease to accrue on the mandatory tender date or Conversion Date,
and the holder of such Undelivered Bond shall not be entitled to any payment
other than the purchase price for such Undelivered Bond, and such Undelivered
Bond shall no longer be outstanding and entitled to the benefits of the
Indenture, except for the payment of the purchase price of such Undelivered Bond
from monies held by the Trustee for such payment.

                WRITTEN NOTICE OF MANDATORY TENDER OR CONVERSION

        The Trustee shall give notice, by first class mail, to the holders of
all Bonds subject to mandatory tender or Conversion at least fifteen (15) days
before the mandatory tender date while the Bonds accrue interest at Flexible,
Daily or Weekly Rates, and at least thirty (30) days before the mandatory tender
date or Conversion Date while the Bonds accrue interest at a Term Rate.

                             INTEREST PAYMENT DATES

        While this Bond accrues interest at a Flexible Rate, interest is payable
on the day after the last day of each Flexible Rate Period. While this Bond
accrues interest at a Daily Rate or a Weekly Rate, interest is payable on the
first Business Day of each month. During any Term Rate Period, interest is
payable semiannually on the fifteenth day of the May or November after the
commencement of such Term Rate Period and the fifteenth day of each May or
November thereafter; provided that the last Interest Payment Date for any Term
Rate Period shall be the first Business Day that falls on or after the fifteenth
day of the May or November in which the Term Rate Period ends.

                               OPTIONAL REDEMPTION

        While this Bond accrues interest at a Daily Rate or a Weekly Rate, this
Bond is subject to optional redemption on any date, and while this Bond accrues
interest at a Flexible Rate, this Bond is subject to optional redemption on any
Interest Payment Date, in each case, at a redemption price equal to 100% of the
principal amount hereof, plus accrued interest to the redemption date. Interest
due on any redemption date which is also an Interest Payment Date shall be paid
in accordance with the procedures set forth in the Indenture for payment of
interest.

        [For Subseries 1998A-1 and Subseries 1998A-2] While this Bond accrues

together with accrued interest, if any, to the redemption date.

        [For Subseries 1998A-3 and Subseries 1998A-4 Bonds] While this Bond
accrues interest at a Term Rate, this Bond is subject to optional redemption at
a redemption price equal to 100% of the principal amount thereof, plus accrued
interest hereon to the redemption date and plus premium, in whole or in part, on
any date on and after July 1, 2008, as follows:

                     Redemption Period                Redemption Price
                     -----------------                ----------------

                    [Delete if no Letter of Credit effective]

        This Bond is subject to mandatory redemption prior to maturity upon the
occurrence of a Mandatory Redemption Event at a redemption price equal to 100%
of the principal amount of this Bond, plus accrued interest to the redemption
date. The manner of redeeming Bonds is described in detail in the Indenture.

                          SPECIAL MANDATORY REDEMPTION

                        EXTRAORDINARY OPTIONAL REDEMPTION

        This Bond is subject to extraordinary optional redemption by the Issuer,
at the direction of the Borrower, in whole or in part, on any Interest Payment
Date during any Term Rate Period, at a redemption price equal to 100% of the
principal amount of this Bond, plus accrued interest, if any to the redemption
date, if one or more of the following events shall have occurred within the
preceding year:

               (a) Any Project shall have been damaged or destroyed to such
extent that, in the opinion of the Borrower, (i) normal operations at the
Project are prevented or are likely to be prevented for a period of four
consecutive months, or (ii) the restoration of such Project is not economically
feasible.

               (b) Title to, or the temporary use of, all or substantially all
of a Project shall have been taken under the exercise of the power of eminent
domain by any governmental authority, or person, firm or corporation acting
under governmental authority which, in the opinion of the Borrower, is likely to
result in normal operations at such Project being prevented for a period of four
consecutive months.

               (c) Changes, which the Borrower cannot reasonably control or
overcome, in the economic availability of materials, supplies, labor, equipment
and other properties and things necessary for the efficient operation of a
Project shall have occurred, or technological or other changes shall have
occurred which, in the opinion of the Borrower, render uneconomic the continued
operation of a Project.

               (d) Any court or administrative body shall enter a judgment,
order or decree requiring cessation of all or any substantial part of operations
at a Project, to such an extent that, in the opinion of the Borrower, normal
operations at such Project are likely to be prevented for a period of four
consecutive months.

               (e) As a result of any changes in the State Constitution or the
Constitution of the United States of America or as a result of legislation or
administrative action (whether state or federal) or by final decree, judgment or
order of any court or administrative body (whether state or federal) entered
after the contest thereof by the Borrower in good faith, the Loan Agreement
shall have become void or unenforceable or impossible of performance in
accordance with the intent and purposes of the parties, or shall have been
declared to be unlawful, or unreasonable burdens or excessive liabilities shall
have been imposed on the Issuer or the Borrower, including, without limitation,
federal, State or other ad valorem, property, income or other taxes not being
imposed on the date of the Loan Agreement.


                              DEFAULT ACCELERATION

        In case an Event of Default shall have occurred, the principal of all
Bonds then outstanding under the Indenture may become due and payable prior to
their scheduled maturity date.

                               GENERAL PROVISIONS

        The provisions of this Section shall apply at all times from and after
the date of issuance of this Bond.

        Except during such period of time as the Bonds are held under DTC's
"Book-Entry Only System," the ownership of this Bond may be transferred (in an
amount which is an Authorized Denomination; provided that the portion thereof
retained is itself an Authorized Denomination) only upon presentation and
surrender of this Bond at the Principal Office of the Trustee together with an
assignment duly executed by the Registered Owner hereof or its duly authorized
attorney-in-fact in such form as shall be satisfactory to the Trustee, and
subject to the provisions made therefor in the Indenture; provided that the
Trustee shall not be required to make any such transfer of any Bond during the
ten (10) Business Days immediately preceding the selection of Bonds for
redemption or, with respect to a Bond, after such Bond or any portion thereof
has been selected for redemption.

        The Trustee shall cause notice of any redemption of Bonds to be mailed
by first class mail, postage prepaid, to the Registered Owners of all Bonds to
be redeemed at the registered addresses appearing in the Registration Books kept
for such purpose pursuant to the Indenture. Each such notice shall (i) be mailed
at least fifteen (15) days prior to the redemption date for Bonds which accrue
interest at a Daily, Weekly or Flexible Rate and at least thirty (30) days prior
to the redemption date for Bonds which accrue interest at a Term Rate, (ii)
identify the Bonds to be redeemed, if less than all Bonds are to be redeemed
(specifying the CUSIP numbers, if any, assigned to the Bonds), (iii) specify the
redemption date and the redemption price and (iv) state that on the redemption
date the Bonds called for redemption will be payable at the Principal Office of
the Trustee, that from the redemption date interest will cease to accrue and
that no representation is made as to the accuracy or correctness of the CUSIP
numbers printed therein or on the Bonds; provided, however, that so long as DTC
or its nominee is the sole Registered Owner of the Bonds under DTC's "Book-Entry
Only System," redemption notices will be sent to Cede & Co. Any failure on the
part of DTC or a Direct Participant to give such notice to the Beneficial Owner
or any defect therein shall not affect the sufficiency or validity of any
proceedings for the redemption of the Bonds.

        If at the time of mailing of any notice of an optional redemption there
shall not have been deposited with the Trustee moneys sufficient to redeem all
the Bonds called for redemption, such notice may state that it is conditioned
upon the deposit with the Trustee on or prior to the redemption date of moneys
sufficient to pay the redemption price of the Bonds to be redeemed plus
interest, if any, accrued thereon to the date of redemption, and such notice
shall be of no effect unless such moneys are so deposited.

        Failure on the part of the Trustee to give such notice or any defect
therein shall not affect the validity of any proceedings for the redemption of
the Bonds. By the date fixed for any such redemption, due provision shall be
made with the Trustee for the payment of the principal of, premium, if any, and
interest on the Bonds to be redeemed on the date of redemption. If notice of
redemption is given and if due provision for payment of the redemption price is
made, all as provided in the Indenture, the Bonds or portions thereof which are
to be redeemed shall not bear interest after the date fixed for redemption, and
shall not be entitled to any benefit or security under





                                       26
<PAGE>   32

the Indenture, except for the right of the Registered Owner to receive the
redemption price out of the funds provided for such payment.

        Provisions may be made for the payment of amounts represented by the
Bonds as provided in the Indenture, in which event all liability of the Issuer
to the owners of the applicable Bonds for the payment of such Bonds shall
forthwith cease, terminate and be completely discharged, and thereupon it shall
be the duty of the Trustee to hold such funds (but only for the period specified
and as provided in the Indenture), without liability for interest thereon, for
the benefit of the owners of such Bonds, who shall thereafter be restricted
exclusively to such funds for any claims of whatever nature under the Indenture
or on, or with respect to, said Bonds.

        It is hereby certified and covenanted that this Bond has been duly and
validly authorized, issued and delivered; that all acts, conditions and things
required to exist, happen and be performed precedent to or in the authorization,
issuance and delivery of this Bond do exist, have happened and have been
performed in accordance with law; that the Bonds are limited obligations of the
Issuer; and that the principal of, premium, if any, and interest on the Bonds
are payable from and secured by the properties, revenues and receipts that
constitute a part of the Trust Estate.

        The Bonds are secured by the Indenture, whereunder the Trustee
undertakes to enforce the rights of the owners of the Bonds and to perform other
duties to the extent and under the conditions stated in the Indenture. In case
an Event of Default shall occur, the principal of and interest on the Bonds then
outstanding may, and, under certain circumstances, shall, be declared to be due
and payable immediately upon the conditions and in the manner provided in the
Indenture; and no interest shall accrue on this Bond from and after the date of
such acceleration. Under the circumstances provided in the Indenture, the
Trustee may, in its discretion, and upon the written request of the Registered
Owners of a majority in aggregate principal amount of the Bonds then outstanding
shall, waive any Event of Default and its consequences; provided, however, that
an Event of Default arising from a default in the payment of the principal of,
premium, if any, or interest on the Bonds may not be waived by the Trustee
without the consent of the Registered Owners of all of the Bonds. The Registered
Owners of the Bonds shall have no right to institute any action, suit or
proceeding at law or in equity to enforce the Indenture, except as provided in
the Indenture; provided, however, that nothing in the Indenture shall affect or
impair the right of the Registered Owner of any Bond to enforce the payment of
the principal of, premium, if any, and interest on such Bond from the source and
in the manner herein expressed.

        The Issuer has reserved the right to amend the Indenture with the
consent of the Borrower as provided therein. Under some (but not all)
circumstances, amendments to the Indenture must be approved by the owners of
greater than fifty percent (50%) or one hundred percent (100%) in aggregate
principal amount of the outstanding Bonds.

        This Bond shall not be valid or become obligatory for any purpose or be
entitled to any security or benefit under the Indenture until the Certificate of
Authentication hereon shall have been signed by the Trustee, or the Tender Agent
as Co-Authenticating Agent, or any successor.

        Section 2.4. Execution; Limited Obligations. The Bonds shall be executed
on behalf of the Issuer with the manual or facsimile signature of the Chairman
of the Commission of the Issuer and attested with the manual or facsimile
signature of the Secretary of the Commission. All authorized facsimile
signatures shall have the same force and effect as manual signatures. In case
any officer of the Issuer whose signature or a facsimile thereof appears on a
Bond shall cease to be such officer before the delivery of such Bond, such
signature or such facsimile shall nevertheless be valid and sufficient for all
purposes, the same as if such officer had remained in the office until delivery.

        THE STATE IS NOT OBLIGATED TO PAY, AND NEITHER THE FAITH AND CREDIT NOR
TAXING POWER OF THE STATE IS PLEDGED TO THE PAYMENT OF, THE PRINCIPAL OR
REDEMPTION PRICE, IF ANY, OF, OR INTEREST ON, THE BONDS. THE BONDS ARE SPECIAL,
LIMITED OBLIGATIONS OF THE ISSUER, PAYABLE SOLELY OUT OF THE REVENUES OR OTHER
RECEIPTS, FUNDS OR MONEYS OF THE ISSUER PLEDGED UNDER THE INDENTURE AND FROM ANY
AMOUNTS OTHERWISE AVAILABLE UNDER THE INDENTURE FOR THE PAYMENT OF THE BONDS.
THE BONDS DO NOT NOW AND SHALL NEVER CONSTITUTE A CHARGE AGAINST THE GENERAL
CREDIT OF THE ISSUER. THE ISSUER HAS NO TAXING POWER.

        No member of the Issuer nor any person executing Bonds for the Issuer
shall be liable personally on the Bonds by reason of the issuance thereof. No
covenant or agreement contained in the Bonds or in this Indenture shall be
deemed to be the covenant or agreement of any member, agent, officer, or
employee of the Issuer in his or her individual capacity, and neither the
members of the Issuer nor any official executing the Bonds shall be liable
personally on the Bonds or be subject to any personal liability or
accountability by reason of the issuance thereof.

        Section 2.5. Conditions Precedent to Delivery of Bonds; Authentication.
The Issuer shall execute and deliver the Bonds to the Trustee, and the Trustee
shall, upon receipt by the Trustee of the purchase price for the Bonds,
authenticate the Bonds and deliver them to the initial purchasers thereof. Prior
to and as a condition precedent to the authentication and delivery of the Bonds
there shall be filed with and delivered to the Trustee in addition to the items
required by Section 6.3 of the Loan Agreement:

               (a) a copy, duly certified by an authorized representative of the
        Issuer, of the resolution adopted by the Issuer authorizing the
        execution and delivery of this Indenture and the issuance of the Bonds;

               (b) original executed counterparts of this Indenture, the Loan
        Agreement and the Tax Certificate;

               (c) a written order of the Issuer, directed to the Trustee,
        instructing the Trustee to authenticate the Bonds and to make them
        available for delivery to the initial purchasers thereof upon payment to
        the Trustee for the account of the Issuer of the sum specified in such
        written order;

               (d) an opinion of Bond Counsel substantially to the effect that
        (A) the Bonds constitute legal, valid and binding special, limited
        obligations of the Issuer, enforceable in





                                       31
<PAGE>   37

        accordance with their terms, subject to bankruptcy, insolvency,
        moratorium, reorganization and other similar laws affecting the rights
        of creditors and to the exercise of judicial discretion in accordance
        with general principles of equity, and (B)(i) the interest on the Bonds
        is not includable for federal income tax purposes in gross income under
        existing statutes, regulations, rulings and court decisions, except for
        interest on any Bond for any period during which such Bond is held by a
        "substantial user" of the Project or a "related person," as such terms
        are used in Section 147(a) of the Code and (ii) under existing law,
        interest on the Bonds is exempt from State personal income taxes.

        No Bond shall be valid or obligatory for any purpose or entitled to any
security or benefit under this Indenture unless and until a certificate of
authentication on such Bond shall have been duly executed by the Trustee or the
Tender Agent. Such executed certificate of the Trustee or the Tender Agent upon
any such Bond shall be conclusive evidence that such Bond has been authenticated
and delivered under this Indenture. The certificate of authentication on any
Bond shall be deemed to have been executed by the Trustee or the Tender Agent if
signed by an authorized officer of the Trustee or the Tender Agent, but it shall
not be necessary that the same officer sign the certificates of authentication
on all Bonds issued hereunder.

        Section 2.6. Redemption of Bonds. The Bonds shall be subject to
redemption prior to maturity as set forth below:

                     (a) Optional Redemption. The Bonds shall be subject to
redemption at the option of the Issuer, in whole or in part, and if in part in
Authorized Denominations, at the direction of the Borrower, from funds available
for such purpose in the Revenue Fund, as follows:

                         (i) if any Subseries accrues interest at a Daily Rate
or a Weekly Rate, each Bond of such Subseries is subject to optional redemption
on any date, and if any Subseries accrues interest at a Flexible Rate, each Bond
of such Subseries is subject to optional redemption on any Interest Payment
Date, in all cases at a redemption price equal to 100% of the principal amount
thereof plus accrued interest to the redemption date. Interest due on any
redemption date which is also an Interest Payment Date shall be paid in
accordance with the procedures set forth in Section 2.2 (G) hereof; and










                                       32

<PAGE>   38

                         (ii) (x) the Subseries 1998A-1 Bonds and Subseries
1998A-2 Bonds (during the initial Term Rate Periods) shall be subject to
optional redemption by the Issuer, at the direction of the Borrower, in whole or
in part on the last day of the respective Term Rate Periods at a redemption
price equal to 100% of the principal amount thereof plus accrued interest, if
any, to the redemption date.

                              (y) the Subseries 1998A-3 Bonds and Subseries
1998A-4 Bonds (during the initial Term Rate Periods) shall be subject to
optional redemption by the Issuer, at the direction of the Borrower, on and
after July 1, 2008, in whole or in part on any date at the redemption prices set
forth below (expressed as percentages of principal amount), plus accrued
interest, if any, to the redemption date:

                        Redemption Period               Redemption Price
                        -----------------               ----------------

               July 1, 2008 through June 30, 2009             101.0%
               July 1, 2009 through June 30, 2010             100.5
               July 1, 2010 and thereafter                    100.0


                         (iii) during any subsequent Term Rate Periods, any
Subseries of Bonds shall be subject to optional redemption by the Issuer, at the
direction of the Borrower, on any date ten years after the Conversion Date at a
redemption price of 101.5% (expressed as a percentage of principal amount) for
the first year, such redemption price declining .5% each year thereafter until
such redemption price equals 100% of the principal amount of Bonds to be
redeemed, plus accrued interest, if any, to the redemption date; provided that
such optional redemption dates and redemption prices may be changed by a
supplemental indenture approved by the Borrower and filed with the Trustee,
accompanied by a Favorable Opinion of Bond Counsel, and, provided, further, that
any change in such redemption dates and redemption prices shall be effective
only if such supplemental indenture is approved prior to the applicable
Conversion Date or beginning of the Term Rate Period.

        If a Letter of Credit is then in effect for a Subseries and the
redemption price includes any premium, and the Letter of Credit so provides the
right of the Borrower to direct an optional redemption is subject to the
condition that the Trustee has received, prior to the date on which notice of
redemption is required to be given to the Owners, written confirmation from the
Letter of Credit Issuer that it can draw under the Letter of Credit on the
proposed redemption date in an aggregate amount sufficient to cover the
principal of and premium and interest due on the redemption date.

                      (b) Special Mandatory Redemption. The Bonds shall be
subject to special mandatory redemption prior to maturity on a date selected by
the Borrower not later than 180 days after the occurrence of a Determination of
Taxability at a redemption price equal to 100% of the principal amount thereof,
plus accrued interest to the redemption date. Any such special mandatory
redemption shall be in whole unless it is finally determined as evidenced by a
Favorable Opinion of Bond Counsel delivered and addressed to the Trustee that
less than all of the Bonds may be redeemed without adversely affecting the
exclusion from gross income for federal income tax purposes of interest on the
remaining Bonds, in which case only the principal amount of Bonds indicated in
such Opinion need be redeemed.





                                       33
<PAGE>   39

                      If the Trustee receives written notice from any Owner
stating that (i) the Owner has been notified in writing by the Internal Revenue
Service that it proposes to include the interest on any Bond in the gross income
of such Owner for the reasons stated in the definition of "Determination of
Taxability" or any other proceeding has been instituted against such Owner which
may lead to a "final determination" or "final judgment" as described in the
aforesaid definition, and (ii) such Owner will afford the Borrower the
opportunity to contest the same, either directly or in the name of such Owner,
until a conclusion of any appellate review, if sought, the Trustee shall
promptly give notice of the receipt of any written notice described above to the
Borrower, the Issuer and the Owners of Bonds then Outstanding. If a "final
determination" or "final judgment" thereafter occurs and written notice thereof
is given to the Trustee by such Owner, the Trustee shall make demand for
prepayment of the unpaid Loan payments (or necessary portions thereof as
specified in the foregoing Opinion) from the Borrower and give notice of the
special mandatory redemption of the appropriate amount of Bonds on the date
selected by the Borrower within the required period of 180 days. In taking any
action or making any determination under this Section 2.6(b), the Trustee may
rely on an opinion of counsel.

                      (c) Extraordinary Optional Redemption. The Bonds shall be
subject to extraordinary optional redemption by the Issuer, at the direction of
the Borrower, in whole or in part, on any date during any Term Rate Period, at a
redemption price equal to 100% of the principal amount thereof, plus accrued
interest, if any, to the redemption date, if one or more of the following events
shall have occurred within the preceding year:

                          (i) Any Project shall have been damaged or destroyed
        to such extent that, in the opinion of the Borrower, (A) normal
        operations at the Project are prevented or are likely to be prevented
        for a period of four consecutive months, or (B) the restoration of the
        Project, is not economically feasible.

                          (ii) Title to, or the temporary use of, all or
        substantially all of a Project shall have been taken under the exercise
        of the power of eminent domain by any governmental authority, or person,
        firm or corporation acting under governmental authority which, in the
        opinion of the Borrower, is likely to result in normal operations at the
        Project being prevented for a period of four consecutive months.

                          (iii) Changes, which the Borrower cannot reasonably
        control or overcome, in the economic availability of materials,
        supplies, labor, equipment and other properties and things necessary for
        the efficient operation of a Project shall have occurred, or
        technological or other changes shall have occurred which, in the opinion
        of the Borrower, render uneconomic the continued operation of a Project.

                          (iv) Any court or administrative body shall enter a
        judgment, order or decree requiring cessation of all or any substantial
        part of operations at a Project, to such an extent that, in the opinion
        of the Borrower, is likely to result in normal operations at such
        Project being prevented for a period of four consecutive months.

                          (v) As a result of any changes in the State
        Constitution or the Constitution of the United States of America or as a
        result of legislation or administrative action (whether state or
        federal) or by final decree, judgment or order of any court or





                                       34
<PAGE>   40

        administrative body (whether state or federal) entered after the contest
        thereof by the Borrower in good faith, the Loan Agreement shall have
        become void or unenforceable or impossible of performance in accordance
        with the intent and purposes of the parties, or shall have been declared
        to be unlawful, or unreasonable burdens or excessive liabilities shall
        have been imposed on the Issuer or the Borrower, including, without
        limitation, federal, state or other ad valorem, property, income or
        other taxes not being imposed on the date of the Loan Agreement.

                      (d) Mandatory Redemption. If a Letter of Credit is in
effect for any Subseries, and if the Letter of Credit so provides, the Bonds of
such Subseries shall be subject to mandatory redemption prior to maturity by the
Issuer in whole at a redemption price equal to 100% of the principal amount
thereof, plus accrued interest to the redemption date, upon receipt by the
Trustee of a written notice from the Letter of Credit Issuer directing the
Trustee to draw under the Letter of Credit in an amount necessary to redeem the
Bonds of such Subseries as a result of the occurrence of an event of default
under the Reimbursement Agreement (a "Mandatory Redemption Event").

        Section 2.7. Selection of Bonds for Redemption. In the event that fewer
than all Bonds subject to redemption are to be redeemed, Bonds shall be selected
for redemption in the following manner; provided that the Bonds that remain
Outstanding shall be in Authorized Denominations:

                     (a) If Bonds are subject to special mandatory redemption
pursuant to Section 2.6(b) or extraordinary optional redemption pursuant to
Section 2.6(c), or if the Bonds are subject to optional redemption pursuant to
Section 2.6(a) and the Borrower notifies the Trustee that such redemption
relates to a specific Project (as described in Exhibit A hereto), Bonds shall be
selected for redemption, by lot, from one or more Subseries that relates to such
Project. If more than one Subseries relates to such Project, the Bonds to be
redeemed shall be selected on a pro rata basis among each such Subseries and by
lot within a Subseries.

                     (b) If the Bonds are subject to optional redemption
pursuant to Section 2.6(a) and the Borrower does not notify the Trustee that
such redemption relates to a specific Project. Bonds shall be selected for
redemption by the Trustee, on a pro rata basis among all Subseries, and by lot
within a Subseries, first, from Bonds subject to such redemption (other than
Bonds owned of record by the Borrower), and, second, from Bonds owned of record
by the Borrower subject to such redemption; provided that, upon any optional or
extraordinary optional redemption, at the Borrower's direction (and for so long
as no Event of Default then exists), Pledged Bonds, if any, shall be redeemed
first.

                     (c) In the case of Bonds of varying denominations, the
Trustee shall, to the extent practicable, treat each Bond as representing that
number of units of Bonds which is obtained by dividing the face amount thereof
by the smallest Authorized Denomination. If it is determined that one or more,
but not all, of the units of principal amount represented by any such Bond is to
be called for redemption, then upon notice of intention to redeem such unit or
units of principal, the Bondholder of such Bond shall forthwith surrender such
Bond to the Trustee for (i) payment to such Bondholder of the redemption price
of the unit or units of its Bond called for redemption and (ii) delivery to such
Bondholder of a new Bond or Bonds in an aggregate principal amount equal to the
unredeemed balance of such Bond. New Bonds representing the unredeemed balance
of the





                                       35
<PAGE>   41

principal amount of such Bond shall be issued to the Bondholder thereof without
charge therefor. If the Bondholder of any such Bond of a denomination greater
than the principal amount thereof called for redemption shall fail to present
such Bond to the Trustee for payment and exchange as aforesaid, such Bond shall,
nevertheless, become due and payable on the date fixed for redemption to the
extent of the principal amount called for redemption (and to that extent only).

        Section 2.8. Notice of Redemption. (a) The Borrower shall deliver notice
to the Trustee of its intention to prepay the Loan and cause the Bonds to be
called for optional redemption or extraordinary optional redemption (as
described in Section 2.6 hereof) at least thirty (30) days prior to the proposed
redemption date of Flexible Rate, Daily Rate and Weekly Rate Bonds, and at least
forty-five (45) days prior to the proposed redemption date of Term Rate Bonds.
Any notice from the Borrower or the Issuer to the Trustee pursuant to either of
the preceding two sentences shall state that all conditions precedent contained
herein to the applicable redemption have been complied with. The Trustee shall
cause notice of any redemption of Bonds hereunder to be mailed by first class
mail, postage prepaid, to the Owners of all Bonds to be redeemed at the
registered addresses appearing in the Registration Books. Each such notice shall
(i) be mailed at least fifteen (15) days prior to the redemption date for Daily,
Weekly and Flexible Rate Bonds and at least thirty (30) days prior to the
redemption date for Term Rate Bonds, (ii) identify the Bonds to be redeemed if
less than all Bonds are to be redeemed (specifying the CUSIP numbers, if any,
assigned to the Bonds), (iii) specify the redemption date and the redemption
price, and (iv) state that on the redemption date the Bonds called for
redemption will be payable at the Principal Office of the Trustee, that from
that date interest will cease to accrue and that no representation is made as to
the accuracy or correctness of the CUSIP numbers printed therein or on the
Bonds; provided, however, that so long as DTC or its nominee is the sole Owner
of the Bonds under DTC's "Book-Entry Only System," redemption notices will be
sent to Cede & Co. Any failure on the part of DTC or a Direct Participant (as
hereinafter defined) to give such notice to the Beneficial Owner or any defect
therein shall not affect the sufficiency or validity of any proceedings for the
redemption of the Bonds. No defect affecting any Bond, whether in the notice of
redemption or mailing thereof (including any failure to mail such notice), shall
affect the validity of the redemption proceedings for any other Bonds.

                     (b) Conditional Notice. If at the time of mailing of notice
of an optional redemption there shall not have been deposited with the Trustee
moneys sufficient to redeem all the Bonds called for redemption, such notice may
state that it is conditioned upon the deposit with the Trustee on or prior to
the redemption date of moneys sufficient to pay the redemption price of the
Bonds to be redeemed plus interest, if any, accrued thereon to the date of
redemption, and such notice shall be of no effect (and the redemption shall not
occur) unless such moneys are so deposited.

                     (c) Additional Notice of Redemption. In addition to the
redemption notice required above, if there is more than one Owner of the Bonds,
further notice (the "Additional Notice") shall be given by the Trustee as set
forth below. No defect in the Additional Notice nor any failure to give all or
any portion of the Additional Notice shall in any manner defeat the
effectiveness of a call for redemption if notice is given as prescribed in
paragraph (a) above.

                         (1) Each Additional Notice shall contain the
information required in paragraph (a) above for an official notice of redemption
plus (i) the date of the Bonds as originally issued; (ii) the interest rate
determination method for, or the rate of interest borne by, each Bond





                                       36
<PAGE>   42

being redeemed; (iii) the maturity date of each Bond being redeemed; and (iv)
any other descriptive information needed to identify accurately the Bonds being
redeemed.

                         (2) Each Additional Notice shall be sent at least
thirty (30) days (fifteen (15) days in the case of Bonds accruing interest at
Daily, Weekly or Flexible Rates) before the redemption date by registered or
certified mail or overnight delivery service to the following registered
securities depositories: The Depository Trust Company of New York, New York,
Midwest Securities Trust Company of Chicago, Illinois, and Philadelphia
Depository Trust Company of Philadelphia, Pennsylvania, and to such other
registered securities depositories as may be specified by the Borrower to the
Trustee in writing and to one or more national information services that
disseminate notices of redemption of obligations such as the Bonds as shall be
specified by the Borrower to the Trustee in writing.

                         (3) The Trustee's agreement to give any Additional
Notice is made as a matter of courtesy and accommodation only and the Trustee
shall incur no liability to any Person for its failure to give such Additional
Notices.

        Section 2.9. Effect of Redemption. If payment of the redemption price of
the Bonds has been duly provided for on the redemption date, then interest on
the Bonds called for redemption will cease to accrue on such date, and the
Owners will have no rights with respect to such Bonds nor will they be entitled
to the benefits of the Indenture except to receive payment of the redemption
price thereof and unpaid interest accrued to the date fixed for redemption.

        Section 2.10. Optional Redemption only at Direction of Borrower.
Optional redemption of the Bonds by the Issuer pursuant to Sections 2.6(a) and
(c) shall only be made at the direction and in the sole discretion of the
Borrower, and the Issuer shall take no action with respect to Sections 2.6(a) or
(c) without the prior written direction of the Borrower.

        Section 2.11. Book-Entry Bonds. (i) Except as provided in subsection
(iii) of this Section, the Bonds shall all be registered as to both principal
and interest in the name of and held by Cede & Co., as nominee of DTC. Payment
of both principal and interest for any Bond registered as of the applicable
Record Date in the name of Cede & Co., as nominee of DTC, shall be made by the
Trustee with immediately available funds to the account of Cede & Co., as
nominee of DTC, on the interest or principal payment date for the Bonds, as the
case may be, at the address indicated on the Registration Books.

                      (ii) The Bonds shall be initially issued in the form of
one authenticated fully registered Bond for each Subseries. Upon initial
issuance, the ownership of such Bond shall be registered in the Registration
Books in the name of Cede & Co., as nominee of DTC. The Trustee and the Issuer
may treat DTC (or its nominee) as the sole and exclusive owner of the Bonds
registered in its name for the purposes of payment of the principal or
redemption price of or interest on the Bonds, selecting the Bonds or portions
thereof to be redeemed, giving any notice permitted or required to be given to
Bondholders under this Indenture, registering the transfer of the Bonds,
obtaining any consent or other action to be taken by Bondholders and for all
other purposes whatsoever; and neither the Trustee nor the Issuer shall be
affected by any notice to the contrary. Neither the Trustee nor the Issuer shall
have any responsibility or obligation to any DTC participant (herein a "Direct
Participant"), any person claiming a beneficial ownership interest in the Bonds





                                       37
<PAGE>   43

under or through DTC or any Direct Participant (herein, a "Beneficial Owner"),
or any other person which is not shown on the Registration Books as being a
Bondholder. The Issuer and the Trustee shall have no responsibility with respect
to the accuracy of any records maintained by DTC, Cede & Co., or any Direct
Participant with respect to any ownership interest in the Bonds, the payment by
DTC or any Direct Participant to any Beneficial Owner of any amount in respect
of the principal or redemption price of or interest on the Bonds, the delivery
to any Direct Participant or any Beneficial Owner of any notice which is
permitted or required to be given to Bondholders under this Indenture, the
selection by DTC or any Direct Participant of any Person to receive payment in
the event of a partial redemption of the Bonds, or any consent given or other
action taken by DTC as Bondholder. The Trustee shall pay all principal of and
premium, if any, and interest on the Bonds only to or upon the order of Cede &
Co., as nominee of DTC, and all such payments shall be valid and effective to
fully satisfy and discharge the Issuer's obligations with respect to the
principal of, premium, if any, and interest on the Bonds to the extent of the
sum or sums so paid without the requirement that DTC surrender the Bond so
redeemed (except upon final payment). Upon delivery by DTC to the Trustee of
written notice to the effect that DTC has determined to substitute a new nominee
in place of Cede & Co., and subject to the provisions herein with respect to
Record Dates, the words "Cede & Co.", in this Indenture shall refer to such
successor nominee.

                      (iii) In the event that the Issuer, at the direction of
the Borrower, determines to make available to the Beneficial Owners of the Bonds
definitive Bonds, the Issuer will notify DTC and the Trustee, in writing,
whereupon DTC will notify Direct Participants, of the availability through DTC
of definitive Bonds. In such event, the Issuer shall issue definitive Bonds
registered in such names and in such amounts as shall be designated in writing
by DTC. DTC may determine to discontinue providing its services with respect to
the Bonds at any time by giving reasonable notice to the Issuer and the Trustee
and discharging its responsibilities with respect thereto under applicable law.
Under such circumstances, the Issuer and the Trustee shall be obligated to
deliver definitive Bonds as described in this Indenture registered in such names
and in such amounts as shall be designated by DTC. In the event definitive Bonds
are issued, the provisions of this Indenture shall apply to, among other things,
the transfer and exchange of such definitive Bonds and the method of payment of
principal of, redemption price and interest on such definitive Bonds. Whenever
DTC requests the Issuer to do so, the Issuer will cooperate with DTC in taking
appropriate action (a) to make available one or more separate definitive Bonds
evidencing the Bonds to any Direct Participant having Bonds credited to its DTC
account or (b) to arrange for another securities depository to maintain custody
of definitive Bonds.

                      (iv) In connection with any notice or other communication
to be provided to Bondholders pursuant to this Indenture with respect to any
consent or other action to be taken by Bondholders, the Issuer or the Trustee,
as the case may be, the Trustee shall establish a record date for such consent
or other action and give DTC notice of such record date not less than fifteen
(15) calendar days in advance of such record date to the extent practicable.

                      (v) The expense of providing definitive Bonds shall be
borne by the Borrower.

        Section 2.12. Extension of Letter of Credit in Anticipation of
Expiration. At least forty-five (45) days (or such shorter period as shall be
acceptable to the Trustee in its sole discretion) prior to the Interest Payment
Date next preceding the Termination Date of any existing Letter of Credit,





                                       38
<PAGE>   44

the Borrower may provide for the delivery to the Trustee of an amendment to the
Letter of Credit which extends the Termination Date to a date that is not
earlier than one year from its then current Termination Date or the maturity of
the Bonds if shorter. If the Letter of Credit is so extended, the mandatory
tender for purchase pursuant to clause (c) of Section 3.2 shall not occur;
otherwise, the Trustee shall take all action necessary to call the Bonds for
mandatory tender for purchase pursuant to clause (c) of Section 3.2 on the
Interest Payment Date next preceding such Termination Date; provided that if the
Borrower shall have notified the Trustee in writing that it expects to meet all
the conditions for the delivery of an amendment extending the existing Letter of
Credit on or before the Interest Payment Date next preceding the Termination
Date of the existing Letter of Credit, then the notice of mandatory tender for
purchase pursuant to clause (c) of Section 3.2 shall state that it is subject to
rescission, and the Trustee shall rescind such notice, if such conditions are so
met (in which case such mandatory purchase shall not occur).

        Section 2.13. Delivery of Initial Letter of Credit; Replacement of
Letter of Credit. On any date on which the Bonds are subject to mandatory tender
or optional redemption, the Borrower may cause to be delivered to the Trustee an
Initial Letter of Credit for one or more Subseries. On any date on which the
Bonds are subject to optional redemption, the Borrower may provide for the
delivery to the Trustee of (1) an Alternate Letter of Credit which shall have
terms which are the same in all material respects (except as to the Termination
Date and except any changes pursuant to this Indenture with respect to interest
or premium coverage in connection with a concurrent Rate Period conversion) as
the existing Letter of Credit, which shall have a Termination Date that is not
less than one year from the date of its delivery and not sooner than the
Termination Date of the existing Letter of Credit, or the maturity of the Bonds,
if shorter, and which shall be issued by a Qualified Issuer; (2) an opinion of
counsel to the Qualified Issuer in form satisfactory to the Trustee with respect
to the validity, binding effect and enforceability of such Alternate Letter of
Credit; and (3) an opinion of Bond Counsel to the effect that such action will
not adversely affect the exclusion from gross income of interest on the Bonds
for Federal income tax purposes, and if the requirements set forth in this
Section are met, then the Trustee shall accept such Alternate Letter of Credit
and promptly surrender for cancellation the previously held Letter of Credit to
the issuer thereof in accordance with the terms of such Letter of Credit. The
Borrower shall give the Trustee at least forty-five (45) days (or such shorter
period as shall be acceptable to the Trustee in its sole discretion) notice of
the proposed replacement of the Letter of Credit, which notice shall include the
expected ratings, if any, applicable to the Bonds after the proposed replacement
of the Letter of Credit. Upon receipt of such notice, the Trustee shall take all
action necessary to call the Bonds for mandatory tender for purchase pursuant to
clause (c) of Section 3.2 on the date on which the Letter of Credit is to be
replaced. Any Alternate Letter of Credit shall, upon its acceptance by the
Trustee, be deemed to be a Letter of Credit for all purposes of this Indenture.

        Section 2.14. Notice to Owners. The Trustee shall give notice to the
Owners and the Remarketing Agent, in the name of the Issuer, of the proposed
replacement of the existing Letter of Credit, of the ratings expected to be
applicable to the Bonds after the proposed replacement and of the mandatory
tender date as required under clause (c) of Section 3.2 by first class mail,
postage prepaid, not less than fifteen (15) days prior to the proposed
replacement date.

        Section 2.15. Reduction. In each case that Bonds are redeemed or deemed
to have been paid pursuant to this Indenture, the Trustee shall take such action
as may be permitted under the Letter of Credit to reduce the amount available
thereunder to an amount equal to the principal





                                       39
<PAGE>   45

amount of the outstanding Bonds for which the Letter of Credit is effective,
plus interest at the maximum rate required under the Letter of Credit for the
maximum period between Interest Payment Dates plus 14 days; provided that such
action by the Trustee shall not be required if the Letter of Credit so reduces
automatically pursuant to its terms.

        Section 2.16. Other Credit Enhancement; No Credit Enhancement. After a
mandatory purchase of the Bonds pursuant to clause (c) of Section 3.2 or after a
conversion to a Term Rate Period, nothing in this Article II shall limit the
Borrower's right to provide other credit enhancement (such as an Alternate
Letter of Credit or bond insurance) or no credit enhancement as security for the
Bonds; provided that any such credit enhancement shall have administrative
provisions reasonably satisfactory to the Trustee, and the Borrower shall have
furnished to the Trustee a Favorable Opinion of Bond Counsel. During the initial
Term Rate Periods for the Bonds, no credit enhancement shall be required as
security for the Bonds.

                                   ARTICLE III

                      PURCHASE AND REMARKETING OF THE BONDS

        Section 3.1. Optional Tenders for Purchase.

                     (a) Purchase Dates. The Owners of Bonds accruing interest
at Daily Rates or Weekly Rates may elect to have their Bonds (or portions
thereof in amounts equal to any Authorized Denomination) purchased at a purchase
price equal to 100% of the principal amount, plus accrued interest to the
purchase date on the following purchase dates:

                         (i) Bonds accruing interest at Daily Rates may be
tendered for purchase at a purchase price payable in immediately available funds
on any Business Day prior to conversion from a Daily Rate to a different
Interest Rate, upon written, electronic or telephonic notice of tender given to
the Tender Agent, directly or through the Beneficial Owner's Direct Participant,
not later than 11:00 a.m., New York City time, on the purchase date;

                         (ii) Bonds accruing interest at Weekly Rates may be
tendered for purchase at a purchase price payable in immediately available funds
on any Business Day prior to conversion from a Weekly Rate to a different
Interest Rate, upon written or electronic notice of tender given to the Tender
Agent, directly or through the Beneficial Owner's Direct Participant, not later
than 5:00 p.m., New York City time, on a Business Day not less than seven (7)
days prior to the purchase date.

                     (b) Notice of Tender. Each notice of tender:

                         (i) shall, in the case of a written notice, be
delivered to the Tender Agent at its Principal Office and be in form
satisfactory to the Tender Agent;

                         (ii) shall state, whether delivered in writing,
electronically or by telephone, (A) the principal amount of the Bond to which
the notice relates, (B) that the Owner irrevocably demands purchase of such Bond
or a specified portion thereof in an amount equal to any Authorized
Denomination, (C) the date on which such Bond or portion is to be purchased, and
(D) payment instructions with respect to the purchase price; and





                                       40
<PAGE>   46

                         (iii) shall automatically constitute, whether delivered
in writing, electronically or by telephone (A) an irrevocable offer to sell the
Bond (or portion thereof) to which the notice relates on the purchase date at a
purchase price equal to the principal amount of such Bond (or portion thereof)
plus, with respect to Bonds accruing interest at a Daily Rate or a Weekly Rate,
any interest thereon accrued and unpaid as of the purchase date, (B) an
irrevocable authorization and instruction to the Tender Agent to effect transfer
of such Bond (or portion thereof) upon payment of the purchase price to the
Tender Agent on the purchase date, (C) an irrevocable authorization and
instruction to the Tender Agent to effect the exchange of the Bond to be
purchased in whole or in part for other Bonds in an equal aggregate principal
amount so as to facilitate the sale of such Bond (or portion thereof to be
purchased), and (D) an acknowledgment that such Owner will have no further
rights with respect to such Bond (or portion thereof) upon payment of the
purchase price thereof to the Tender Agent on the purchase date, except for the
right of such Owner to receive such purchase price upon delivery of such Bond to
the Tender Agent and that after the purchase date such Owner will hold any
undelivered certificate as agent for the Tender Agent. The determination of the
Tender Agent as to whether a notice of tender has been properly delivered
pursuant to the foregoing shall be conclusive and binding upon the Owner.

                     (c) Bonds to be Remarketed. Not later than 11:00 a.m., New
York City time, on the Business Day immediately following the date of receipt of
any notice of tender (or immediately upon such receipt, in the case of Bonds
accruing interest at Daily Rates), the Tender Agent shall notify, by telephone,
promptly confirmed in writing, the Borrower, the Trustee and the Remarketing
Agent of the principal amount of Bonds (or portions thereof) to be purchased and
the date of purchase.

        Section 3.2. Mandatory Tenders for Purchase.

                     (a) Flexible Rate and Term Rate Bonds. Each Bond accruing
interest at a Flexible Rate shall be subject to mandatory tender for purchase on
the day after the last day of each Flexible Rate Period applicable to such Bond,
at a purchase price equal to 100% of the principal amount thereof, plus interest
accrued during such Flexible Rate Period. Each Bond accruing interest at a Term
Rate shall be subject to mandatory tender for purchase on the last day of the
Term Rate Period applicable to such Bond, at a purchase price equal to 100% of
the principal amount thereof, plus interest accrued to the purchase date. The
Owner of any Bond tendered for purchase as provided in this Section 3.2(a) shall
provide the Tender Agent with written payment instructions for the purchase
price of its Bond on or before tender thereof to the Tender Agent.

                     (b) Conversions between Interest Rates. Bonds to be
converted from one type of Interest Rate to a different type of Interest Rate
(except conversions from a Daily Rate to a Weekly Rate or from a Weekly Rate to
a Daily Rate) are subject to mandatory tender for purchase on the Conversion
Date at a purchase price equal to the principal amount thereof plus accrued
interest, if any; provided that the purchase price for Bonds converted from a
Term Rate on a date when such Bonds are also subject to optional redemption at a
premium shall include an amount equal to the premium that would be payable if
such Bonds were redeemed on such date.

                     (c) Prior to Expiration or upon Replacement of Letter of
Credit. The Bonds are subject to mandatory tender for purchase (i) on the Letter
of Credit Tender Date, unless at least forty-five (45) days (or such shorter
period as shall be acceptable to the Trustee in its sole discretion)





                                       41
<PAGE>   47

prior to such Letter of Credit Tender Date the Trustee has received written
notice from the Letter of Credit Issuer that the Letter of Credit has been or
will be extended and (ii) on the date the Letter of Credit is replaced pursuant
to Section 2.13, in each case at a purchase price equal to the principal amount
thereof plus accrued interest to the mandatory tender date; provided that, if a
Letter of Credit is delivered on a date on which the Bonds are also subject to
optional redemption at a premium, the purchase price shall include an amount
equal to the premium that would be payable if such Bonds were redeemed on that
date.

                     (d) Notice of Mandatory Tender. The Trustee shall give
notice of mandatory tender for purchase to the Owners of Bonds subject to
mandatory tender pursuant to this Section 3.2 by first class mail, not less than
fifteen (15) days prior to the mandatory tender date, except that not less than
thirty (30) days notice shall be given to the Owners of Bonds accruing interest
at a Term Rate. If the Bonds are in certificated form, such notice shall include
information with respect to required delivery of Bond certificates and payment
of the purchase price.

        Section 3.3. Remarketing and Purchase.

                     (a) Remarketing of Tendered Bonds. Unless otherwise
instructed by the Borrower, the Remarketing Agent shall offer for sale, and use
its best efforts to find purchasers for, all Bonds (or portions thereof) for
which notice of tender has been received pursuant to Section 3.1(b) or 3.2(d).
While the Bonds are in book-entry only form, the Remarketing Agent will make
payment of the purchase price for tendered Bonds in accordance with the
procedures established by DTC. If the book-entry only system is not in effect,
the terms of any sale by the Remarketing Agent shall provide for the payment of
the purchase price for tendered Bonds by the Remarketing Agent to the Trustee
(i) in immediately available funds not later than 3:00 p.m., New York City time,
on the purchase date, in the case of Bonds accruing interest at Flexible Rates,
(ii) in immediately available funds not later than 4:00 p.m., New York City
time, on the purchase date, in the case of Bonds accruing interest at Daily
Rates or Weekly Rates, and (iii) in immediately available funds not later than
12:00 noon, New York City time, on the purchase date, in the case of Bonds
accruing interest at Term Rates. The Remarketing Agent shall not sell any Bond
as to which a notice of conversion from one type of Interest Rate to another has
been given by the Trustee unless the Remarketing Agent has advised the Person to
whom the sale is made of the conversion. The Remarketing Agent shall not, while
any Letter of Credit is in effect, remarket the Bonds to the Issuer, the
Borrower, or any general partner of the Borrower, any affiliate of the Borrower
or any guarantor of the Borrower's obligations, other than Bonds which would
thereupon constitute Pledged Bonds.

                     (b) Purchase of Tendered Bonds.

                         (i) Notice. Not later than 3:00 p.m., New York City
time, on the Business Day immediately preceding the date fixed for purchase of
tendered Bonds (or 12:45 p.m., New York City time, on the purchase date, in the
case of Bonds accruing interest at Daily or Flexible Rates), the Remarketing
Agent shall give notice by telephone, telecopy, electronically or by other
similar communication to the Borrower, the Tender Agent and the Trustee of the
principal amount of tendered Bonds which were remarketed and the amount of
remarketing proceeds received which will be transferred pursuant to Section
3.3(a). Not later than 4:00 p.m. (or 1:00 p.m., in the case of Bonds accruing
interest at Daily, Weekly or Flexible Rates), New York City time, on the date of
receipt of





                                       42
<PAGE>   48

such notice the Tender Agent shall give notice by telephone, telecopy,
electronically or by other similar communication to any Letter of Credit Issuer
and the Borrower, specifying the principal amount of tendered Bonds as to which
the Remarketing Agent has notified the Tender Agent that it has not found a
purchaser at that time. Not later than 3:00 p.m., New York City time, on the
Business Day prior to the purchase date to the extent known to the Remarketing
Agent, but in any event, not later than 11:00 a.m. (or 1:00 p.m., in the case of
Bonds accruing interest at Daily, Weekly or Flexible Rates), New York City time,
on the date fixed for purchase (or two Business Days prior to the date fixed for
purchase in the event tendered Bonds accrue interest at Term Rates), the
Remarketing Agent shall give notice to the Tender Agent by telephone (promptly
confirmed in writing or electronically) of the names, addresses and taxpayer
identification numbers of the purchasers, the denominations of Bonds to be
delivered to each purchaser and, if available, payment instructions for
regularly scheduled interest payments, or of any changes in any such information
previously communicated.


                         (ii) Sources of Payments; Drawings on Letter of Credit.
The Remarketing Agent shall cause to be paid to the Trustee on the date fixed
for purchase of tendered Bonds, all amounts representing proceeds of the
remarketing of such Bonds, such payments to be made in the manner and at the
time specified in Section 3.3(a) above. If such amounts will not be sufficient
to pay the principal amount thereof plus the accrued and unpaid interest thereon
(if any) to the purchase date, the Trustee shall by 2:00 p.m., New York City
time, on the purchase date draw under the Letter of Credit, if any, then held by
the Trustee, if the Letter of Credit so provides, in accordance with its terms
in a manner so as to furnish immediately available funds by 4:00 p.m., New York
City time, on such purchase date, in an amount sufficient, together with the
remarketing proceeds available for such purchase, to enable the Trustee to pay
the purchase price of Bonds to be purchased on such purchase date. If no Letter
of Credit is then held by the Trustee, or if the Letter of Credit shall have
been dishonored, the Borrower shall deliver or cause to be delivered to the
Trustee immediately available funds in an amount equal to such deficiency prior
to 2:30 p.m., New York City time, on the date set for purchase of tendered Bonds
accruing interest at Daily Rates, Weekly Rates and Term Rates (3:00 p.m., New
York City time, in the case of Flexible Rate Bonds) (the obligation of the
Borrower to deliver such moneys not being conditioned upon receipt by the
Borrower of the foregoing notice from the Trustee). All monies received by the
Trustee as remarketing proceeds or from drawings under any Letter of Credit and
additional amounts, if any, received from the Borrower shall be deposited by the
Trustee in the appropriate account of the Bond Purchase Fund to be used solely
for the payment of the purchase price of tendered Bonds and shall not be
commingled with other funds held by the Trustee.

                         (iii) Payments by the Trustee. Not later than 4:00
p.m., New York City time, on the date set for purchase of tendered Bonds and
upon receipt by the Trustee of 100% of the aggregate purchase price of the
tendered Bonds, the Trustee shall pay the purchase price of such Bonds to the
Owners thereof in immediately available funds (or by wire transfer). The Trustee
shall apply such moneys to purchase the tendered Bonds in the following order:
(A) moneys paid to it by the Remarketing Agent as proceeds of the remarketing of
such Bonds by the Remarketing Agent, (B) proceeds of a drawing under any Letter
of Credit, and (C) other monies made available by the Borrower. If sufficient
funds are not available for the purchase of all tendered Bonds, no purchases
shall be consummated, all as further set forth in Section 3.4 hereof.





                                       43
<PAGE>   49

                         (iv) Registration and Delivery of Tendered or Purchased
Bonds. On the date of purchase, the Tender Agent shall register and deliver (or
hold) or cancel all Bonds purchased on any purchase date as follows: (A) Bonds
purchased or remarketed by the Remarketing Agent shall be registered and made
available to the Remarketing Agent by 2:15 p.m., New York City time, in
accordance with the instructions of the Remarketing Agent; (B) Bonds purchased
with proceeds of a drawing under any Letter of Credit shall be held as Pledged
Bonds in accordance with subparagraph (v) below; and (C) Bonds purchased with
amounts provided by the Borrower shall be registered in the name of the Borrower
and shall be held in trust by the Tender Agent on behalf of the Borrower and
shall not be released from such trust unless the Tender Agent shall have
received written instructions from the Borrower. All interest payable on Bonds
registered in the name of the Borrower shall be payable to the Borrower.
Notwithstanding anything herein to the contrary, so long as the Bonds are held
under the book-entry only system in accordance with Section 2.11 hereof, Bonds
will not be delivered as set forth above; rather, transfers of beneficial
ownership of the Bonds to the person indicated above will be effected on the
registration books of DTC pursuant to its rules and procedures.

                         (v) Pledged Bonds. Bonds purchased with proceeds of a
drawing under a Letter of Credit pursuant to this Section shall constitute
"Pledged Bonds" and shall be held by the Tender Agent as agent for the Letter of
Credit Issuer as pledgee of the Borrower pursuant to the Pledge Agreement (and
shall be shown as such on the Registration Books) unless and until (1) the
Trustee and the Tender Agent have written confirmation from the Letter of Credit
Issuer to the extent contemplated by the terms of the Letter of Credit that the
Letter of Credit has been reinstated with respect to such drawing and (2) the
Letter of Credit Issuer has notified the Tender Agent by telephone (thereafter
promptly confirmed in writing) that such Bonds have been released from the
pledge pursuant to the Pledge Agreement and are no longer Pledged Bonds. Pending
reinstatement of the Letter of Credit and release of such pledge as aforesaid,
such Bonds shall not be transferable or deliverable to any party (including the
Borrower) except the Letter of Credit Issuer pursuant to the Pledge Agreement.
Unless the Letter of Credit Issuer has notified the Trustee of the occurrence of
an event of default under the Reimbursement Agreement, all interest payable on
Pledged Bonds shall be payable to the Borrower. Upon receipt by the Trustee of
notice from the Letter of Credit Issuer of the occurrence of an event of default
under the Reimbursement Agreement, all interest payable on Pledged Bonds shall
be payable to the Letter of Credit Issuer. The Remarketing Agent shall, at the
request of the Letter of Credit Issuer, continue to use its best efforts to
arrange for the sale of any Pledged Bonds, subject to full reinstatement of the
Letter of Credit with respect to the drawings with which such Bonds were
purchased, at a price equal to the principal amount thereof plus accrued
interest.

               Notwithstanding anything to the contrary in this subsection, if
and for so long as the Bonds are to be registered in accordance with Section
2.11 hereof, the registration requirements under this subsection (v) shall be
deemed satisfied if Pledged Bonds are (1) registered in the name of DTC or its
nominee in accordance with Section 2.11 hereof, (2) credited on the books of DTC
to the account of the Tender Agent (or its nominee) and (3) further credited on
the books of the Tender Agent (or its nominee) to the account of the Letter of
Credit Issuer (or its designee).

                         (vi) Resale of Bonds Purchased by the Borrower. In the
event that any Bonds are registered to the Borrower pursuant to subparagraph
(iv) above to the extent requested by





                                       44
<PAGE>   50

the Borrower, the Remarketing Agent shall offer for sale and use its best
efforts to sell such Bonds at a price equal to the principal amount thereof plus
accrued interest.

                         (vii) Delivery of Tendered Bonds; Effect of Failure to
Surrender Bonds. All Bonds (other than Bonds held in a book-entry-only system)
to be purchased on any date shall be required to be delivered to the Principal
Office of the Tender Agent not later than (A) 1:00 p.m., New York City time, on
the purchase date in the case of Bonds accruing interest at Flexible or Daily
Rates; (B) 12:00 noon, New York City time, on the purchase date in the case of
Bonds accruing interest at Weekly Rates; or (C) 5:00 p.m., New York City time,
on the second Business Day prior to the purchase date in the case of Bonds
accruing interest at Term Rates. If the Owner of any Bond (or portion thereof)
in certificated form that is subject to optional or mandatory purchase pursuant
to this Article fails to deliver such Bond to the Tender Agent for purchase on
the purchase date, and if the Tender Agent is in receipt of the purchase price
therefor, such Bond (or portion thereof) shall nevertheless be deemed purchased
on the day fixed for purchase thereof and ownership of such Bond (or portion
thereof) shall be transferred to the purchaser thereof as provided in subsection
(b)(iv) above. Any Owner who fails to deliver such Bond for purchase shall have
no further rights thereunder and hereunder except the right to receive the
purchase price thereof upon presentation and surrender of said Bond to the
Tender Agent. The Tender Agent shall, as to any tendered Bonds which have not
been delivered to it (i) promptly notify the Remarketing Agent of such
nondelivery and (ii) cause the Trustee to place a stop transfer against an
appropriate amount of Bonds registered in the name of such Owner(s) on the
Registration Books. The Tender Agent shall cause the Trustee to place such
stop(s) commencing with the lowest serial number Bond registered in the name of
such Owner(s) until stop transfers have been placed against an appropriate
amount of Bonds until the appropriate tendered Bonds are delivered to the Tender
Agent. Upon such delivery, the Tender Agent shall cause the Trustee to make any
necessary adjustments to the Registration Books.

        Section 3.4. Inadequate Funds for Tenders. If the funds available for
purchases of Bonds pursuant to this Article III are inadequate for the purchase
of all Bonds tendered on any purchase date, the Tender Agent shall, after any
applicable grace period: (a) return all tendered Bonds to the Owners thereof;
(b) return all moneys received for the purchase of such Bonds to the Persons
providing such monies; and (c) notify the Issuer and the Remarketing Agent of
the return of such Bonds and moneys and the failure to make payment for tendered
Bonds.

        Section 3.5. [Reserved]

        Section 3.6. Bond Purchase Fund. There is hereby created with the
Trustee a segregated trust fund to be designated the "Bond Purchase Fund". The
Bond Purchase Fund shall consist of three sub-accounts to be designated
respectively the "Remarketing Account", the "Letter of Credit Purchase Account"
and the "Borrower Purchase Account".

        The Trustee shall deposit or cause to be deposited into the Remarketing
Account, when and as received, all moneys delivered to the Trustee as and for
the purchase price of remarketed Bonds by or on behalf of the Remarketing Agent
or the Tender Agent. The Trustee shall disburse moneys from the Remarketing
Account to pay the purchase price of Bonds properly tendered for purchase upon
surrender of such Bonds.





                                       45
<PAGE>   51

        The Trustee shall deposit or cause to be deposited into the Letter of
Credit Purchase Account, when and as received, all proceeds from a drawing under
the Letter of Credit pursuant to Section 3.3(b) hereof. The Trustee shall
disburse moneys from the Letter of Credit Purchase Account to pay the purchase
price of Bonds properly tendered for purchase upon surrender of such Bonds;
provided that such proceeds shall not be applied to purchase Pledged Bonds or
Bonds held in the name of the Issuer, or the Borrower, or to any general partner
of the Borrower, any affiliate of the Borrower or any guarantor of the
Borrower's obligations identified to the Trustee in a certificate of the
Borrower.

        The Trustee shall deposit or cause to be deposited into the Borrower
Purchase Account, when and as received, all moneys delivered to the Trustee by
or for the account of the Borrower pursuant to Section 3.3(b) hereof. The
Trustee shall disburse moneys from the Borrower Purchase Account to pay the
purchase price of Bonds properly tendered for purchase by or on behalf of the
Borrower upon surrender of such Bonds or to reimburse the Letter of Credit
Issuer for drawings under the Letter of Credit for such purpose.

        The funds held by the Trustee in the Bond Purchase Fund shall not
constitute part of the Trust Estate which is subject to the lien of this
Indenture. The moneys in the Bond Purchase Fund shall be used solely to pay the
purchase price of Bonds as aforesaid (or to reimburse the Letter of Credit
Issuer for drawings under the Letter of Credit for such purpose) and may not be
used for any other purposes. It shall be the duty of the Trustee to hold the
moneys in the Bond Purchase Fund, without liability for interest thereon, for
the benefit of the Owners of Bonds which have been properly tendered for
purchase or deemed tendered on the purchase date, and if sufficient funds to pay
the purchase price for such tendered Bonds shall be held by the Trustee in the
Bond Purchase Fund for the benefit of the Owners thereof, each such Owner shall
thereafter be restricted exclusively to the Bond Purchase Fund for any claim of
whatever nature on such Owner's part under this Indenture or on, or with respect
to, such tendered Bond. The provisions of Section 4.8 hereof shall govern any
funds held in the Bond Purchase Fund for such Owners of the Bonds which remain
unclaimed for a period of two years after the applicable purchase date.

                                   ARTICLE IV

                               GENERAL PROVISIONS

        Section 4.1. Authorization for Indenture; Indenture to Constitute
Contract. This Indenture is entered into pursuant to the Refunding Law. In
consideration of the purchase of the Bonds by the Bond Owners, the provisions of

the Bonds, and shall be deemed to be and shall constitute a contract among the
Issuer, the Trustee, any Letter of Credit Issuer, the Remarketing Agent, the
Tender Agent and the Bond Owners. The provisions hereof are covenants and
agreements with such Bond Owners, which the Issuer hereby determines to be
necessary and desirable for the security and payment of the Bonds.

        Section 4.2. Payment of Principal, Premium, if any, and Interest. The
Issuer covenants that it will duly and punctually pay or cause to be paid the
principal of, premium, if any, purchase price of and interest on the Bonds

provided herein and therein according to the true intent and meaning hereof and
thereof, but solely from the payments, revenues and receipts specifically
assigned herein for such purposes as set forth in Section 5.3 and, with respect
to the purchase price of Bonds, Section 3.6 of this Indenture.





                                       46
<PAGE>   52

        Section 4.3. Performance of Covenants; Issuer Warranties. The Issuer
covenants that it will faithfully comply with the stipulations and provisions
required to be performed by it and contained in this Indenture, or in any of its
proceedings pertaining hereto. The Issuer warrants that it is duly authorized
under the laws of the State, including particularly and without limitation the
Refunding Law, to issue the Bonds authorized hereby and to execute this
Indenture and to assign its rights under or with respect to the Loan Agreement
and all amounts payable thereunder or with respect thereto, which hereby are
assigned in the manner and to the extent herein set forth; that all actions on
its part for the issuance of the Bonds and the execution and delivery of this
Indenture have been duly and effectively taken; and that the Bonds are and will
be valid and binding limited obligations of the Issuer enforceable in accordance
with the terms thereof and hereof, except as enforcement thereof and hereof may
be limited by bankruptcy, insolvency, moratorium, reorganization and other
similar laws affecting the rights of creditors and by the application of general
principles of equity, if such remedies are pursued.

        Section 4.4. Instruments of Further Assurance. The Issuer covenants that
it will do, execute, acknowledge and deliver, or cause to be done, executed,
acknowledged and delivered, such indentures supplemental hereto and such further
acts, instruments and transfers as the Trustee or the Borrower reasonably may
require for the better and more effectual assignment to the Trustee of all
payments, revenues and other amounts payable under or with respect to the Loan
Agreement, and any other income and other moneys assigned hereby to the payment
of the principal of, premium, if any, and interest on the Bonds. The Issuer
further covenants that it will not create or suffer to be created any lien,
encumbrance or charge upon its interest in the revenues and other amounts
payable under or with respect to the Trust Estate, except the lien and charge
granted hereby.

        Section 4.5. Limitation on Issuer's Actions. The Issuer shall have no
obligation to undertake any affirmative action, to execute any document, or to
file or record any document or instrument unless it is requested in writing to
do so by the Trustee, the Borrower or other authorized party and its fees and
expenses incurred in taking such actions are tendered to the Issuer by the
requesting party.

        Section 4.6. Registration of Bonds; Trustee Appointed Bond Registrar;
Persons Treated as Owners. (a) Registration. The Trustee is hereby appointed as
registrar of the Bonds and as such shall maintain the Registration Books as
provided by this Indenture. The Registration Books shall note any Bond owned by
the Borrower and shall reflect the information required by the registration
information form contained in Section 2.3 to be provided by Bond Owners in
connection with the transfer of Bonds. At reasonable times and under reasonable
regulations established by the Trustee, the Registration Books may be inspected
and copied by the Borrower, the Issuer, the Tender Agent, the Remarketing Agent
or the Owners (or designated representatives thereof) of at least 25% in
aggregate principal amount of Bonds then Outstanding.

                     (b) Transfer and Exchange; Restrictions on Transfer. UNTIL
JUNE 17, 2000, THE TRUSTEE SHALL NOT REGISTER ANY TRANSFER OR EXCHANGE OF ANY
BONDS UNLESS SUCH TRANSFEREE DELIVERS TO THE TRUSTEE AN INVESTOR LETTER
SUBSTANTIALLY IN THE FORM SET FORTH IN EXHIBIT B TO THIS INDENTURE AND UNLESS
THE BONDS BEAR THE LEGEND IN THE FORM SET FORTH IN EXHIBIT C. The ownership of a





                                       47
<PAGE>   53
Bond may be transferred (in the amount of any Authorized Denomination; provided,
that any portion thereof retained is itself in an Authorized Denomination) only
upon surrender thereof at the Principal Office of the Trustee or, in the case of
tenders pursuant to Article III hereof, at the Principal Office of the Tender
Agent (as agent of the Trustee), accompanied by an assignment, duly executed by
the Owner of such Bond or its duly authorized attorney-in-fact, in such form as
shall be satisfactory to the Trustee or the Tender Agent, as the case may be,
along with the address and social security number or federal employer
identification number of such transferee (or, if registration is to be made in
the name of multiple individuals, of all such transferees) and, if such
transferee is a trust, the name and address of the trustee(s) and the date of
the trust of the proposed transferee. Upon the due presentation of any Bond for
transfer and on request of the Trustee, the Issuer shall execute in the name of
the transferee, and the Trustee or the Tender Agent shall authenticate and
deliver, a new fully registered Bond or Bonds, in any Authorized Denomination,
in an aggregate principal amount equal to the unmatured and unredeemed principal
amount of such transferred fully registered Bond, and bearing interest at the
same rate, and maturing on the same date, as such transferred Bond. All Bonds
surrendered to the Trustee or the Tender Agent for transfer pursuant to this
Section 4.6 shall be cancelled by the Trustee and shall not be redelivered.

                     Bonds may be exchanged at the Principal Office of the
Trustee for a like aggregate principal amount of Bonds of Authorized
Denominations. All Bonds surrendered to the Trustee for exchange pursuant to
this Section 4.6 shall be cancelled by the Trustee and shall not be redelivered.
Neither the Issuer nor the Trustee shall be required to make any such transfer
or exchange of any Bond during the ten (10) Business Days immediately preceding
the selection of the Bonds for redemption or, with respect to a Bond, after such
Bond or any portion thereof has been selected for redemption. Notwithstanding
the foregoing provisions, the Trustee or the Tender Agent shall authenticate and
make available for receipt by the purchaser or purchasers of any Bond tendered
or deemed to be tendered in accordance with the provisions of the form of Bond
contained herein, against payment therefor, a new fully registered Bond or
Bonds, in any Authorized Denomination, in an aggregate principal amount equal to
the principal amount of the Bond so tendered or deemed to be tendered and
bearing interest at the same rate, and maturing on the same date, as such
tendered or deemed tendered Bond.

                     The Trustee shall attach to each Bond issued in transfer or
exchange for a Bond (or a portion of a Bond) called for redemption or mandatory
tender a copy of the notice thereof.

                     (c) Charges. In all cases of the transfer of a Bond, the
Trustee shall register on the Registration Books, such Bond in accordance with
the provisions of this Indenture. The Issuer, the Tender Agent or the Trustee
may make a charge to the Bond Owner for every such transfer and every exchange
of a Bond sufficient to reimburse it for any tax, fee or other governmental
charge required to be paid with respect to such transfer or exchange, and may
demand that such charge be paid before any new Bond is delivered.

                     (d) Ownership. As to any Bond, the person in whose name the
ownership of such Bond shall be registered on the Registration Books shall be
deemed and regarded as the absolute owner thereof for all purposes, and payment
of or on account of the principal of, premium, if any, purchase price of and
interest on any such Bond shall be made only to or upon the order of the
registered Owner thereof or its legal representative. All such payments shall be
valid and effectual to satisfy and discharge the liability upon such Bond,
including the interest thereon, to the extent of the sum or sums so paid.





                                       48
<PAGE>   54

        Section 4.7. Cancellation. All Bonds which have been paid at maturity or
redeemed prior to maturity shall not be reissued but shall be cancelled by the
Trustee. All Bonds which are cancelled by the Trustee shall be disposed of by
the Trustee, and a certificate of the disposition thereof shall be furnished
promptly to the Issuer; provided, however, that if the Issuer shall so direct
the Trustee, the Trustee shall forward the cancelled Bonds to the Issuer.

        Section 4.8. Non-presentment of Bonds. If any check representing payment
of interest, principal, premium or purchase price on any Bond is returned to the
Trustee or the Tender Agent or is not presented for payment by the payee
thereof, or any Bond is not presented for payment of principal or premium at the
maturity or redemption date, or purchase price at the purchase date, if the
proceeds of a remarketing of the Bonds by the Remarketing Agent, or funds
provided by the Borrower or any Letter of Credit Issuer and/or Government
Obligations purchased with such funds, sufficient to pay such interest, or such
principal and premium or purchase price, as is applicable, shall have been made
available to the Trustee or the Tender Agent for the benefit of the Owner of the
applicable Bond, all liability of the Issuer to the Owner of such Bond for such
interest or such principal and premium or purchase price shall forthwith cease,
terminate and be completely discharged, and thereupon it shall be the duty of
the Trustee or the Tender Agent to hold such moneys and/or Government
Obligations, without investing or reinvesting the same and without liability for
interest thereon, for the benefit of the Owner of such Bond, who shall
thereafter be restricted exclusively to such funds for any claim of whatever
nature on such Owner's part under this Indenture or on, or with respect to, such
Bond, and thereafter such Bond shall no longer be considered to be Outstanding.
The Trustee's or Tender Agent's obligation to hold such moneys and/or Government
Obligations with respect to such Bond shall continue for a period equal to two
years following the date on which the applicable payment shall have become due,
at which time the Trustee or the Tender Agent, upon request of the Borrower and
upon payment of all fees and expenses due and owing to it and receipt of
indemnity satisfactory to it, shall surrender such funds so held to the
Borrower. Following such surrender, any claim under this Indenture by the Owner
of such Bond of whatever nature shall be made only upon the Borrower and all
liability of the Issuer, the Trustee and the Tender Agent with respect thereto
shall cease.

        The provisions of this Section 4.8 shall be subject to all applicable
escheat and unclaimed property laws.

        Section 4.9. Rights Under Loan Agreement. This Indenture, the Loan
Agreement and the documents executed by the Borrower in connection therewith,
duly executed counterparts or originals of which have been filed with the
Trustee, set forth the covenants and the obligations of the Issuer, the Borrower
and the Trustee. Reference is hereby made to such documents for detailed
statements of the covenants and obligations set forth therein. The Issuer and
the Trustee agree that the Trustee, for and on behalf of the Bond Owners, in its
name or, to the extent permitted by law, in the name of the Issuer, may enforce
all rights of the Issuer and all obligations of the Borrower under and pursuant
to the Loan Agreement and such documents, subject to the Issuer's right to
enforce the Reserved Rights under the Loan Agreement to carry out its public
purposes in making the Loan.

        Section 4.10. Legal Existence of Issuer. The Issuer covenants that it
will at all times maintain its legal existence and will duly procure any
necessary renewals and extensions thereof; will use its best efforts to
maintain, preserve and renew all the rights, powers, privileges and franchises
owned by it; and will comply with all valid acts, rules, regulations and orders
of any





                                       49
<PAGE>   55

legislative, executive, judicial or administrative body applicable to the Issuer
in connection with the Bonds.

        Section 4.11. Tax-Exempt Status of Bonds. The Issuer covenants to commit
or suffer no act within its control that would alter the status or character of
the Bonds, or the interest to be paid on the Bonds, for purposes of State or
federal taxation.

        Section 4.12. Diminution of, or Encumbrance on, Trust Estate. The Issuer
covenants not to sell, transfer, assign, pledge, release, encumber or otherwise
diminish or dispose of, directly or indirectly, by merger or otherwise, or cause
or suffer the same to occur, or create or allow to be created or to exist any
lien upon, all or any part of its interests in the Trust Estate, except as
expressly permitted by this Indenture.

        Section 4.13. Books, Records and Accounts. The Trustee agrees to keep
proper books for the registration of, and transfer of ownership of, each Bond,
and proper books, records and accounts in which complete and correct entries
shall be made of all transactions relating to the receipt, disbursement,
investment, allocation and application of the proceeds received from the sale of
the Bonds, the Revenues, the documents executed by the Borrower in connection
therewith, the funds and accounts created pursuant to this Indenture, and all
other moneys held by the Trustee hereunder. The Trustee shall, during regular
business hours and upon reasonable prior notice, make such books, records and
accounts available for inspection and copying by the Issuer, the Borrower and
the Bond Owners.

        Section 4.14. Temporary Bonds. Until definitive Bonds are ready for
delivery, there may be executed, and, upon written request of the Issuer, the
Trustee or the Tender Agent shall authenticate and deliver, in lieu of
definitive Bonds, but subject to the same limitations and conditions, temporary
printed, engraved, lithographed or typewritten registered Bonds (without
coupons), in any Authorized Denomination, substantially of the tenor hereinabove
set forth for definitive Bonds, and with such omissions, insertions and
variations as may be appropriate. If temporary Bonds shall be issued, as soon as
is practicable the Issuer shall cause the definitive Bonds to be prepared and to
be executed and deposited with the Trustee, and the Trustee or the Tender Agent,
upon presentation to it at its respective Principal Office of any temporary
Bond, shall cancel the same and authenticate and deliver in exchange therefor at
the required location, without charge to the Owner thereof, a definitive Bond or
Bonds of an equal aggregate principal amount and bearing interest at the same
rate as the temporary Bond or Bonds so surrendered. Until so exchanged the
temporary Bonds shall be entitled in all respects to the same benefit and
security of this Indenture as the definitive Bonds to be issued and
authenticated hereunder.

        Section 4.15. Mutilated, Lost, Stolen or Destroyed Bonds. If any Bond is
mutilated, lost, stolen or destroyed, the Trustee, upon request, shall
authenticate a new Bond, dated as provided in Article II hereof, of the same
denomination and bearing interest at the same rate as the Bond mutilated, lost,
stolen or destroyed; provided, however, that, in the case of any mutilated Bond,
such mutilated Bond shall first be surrendered to the Trustee, and, in the case
of any lost, stolen or destroyed Bond, there shall first be furnished to the
Trustee evidence of such loss, theft or destruction satisfactory to the Trustee,
together with indemnity covering the Trustee, the Tender Agent and the Issuer
satisfactory to the Trustee and the Issuer. If any such Bond shall have matured,
instead of issuing a replacement Bond the Issuer may pay the same. The Trustee
and the Issuer may





                                       50
<PAGE>   56

charge the Owner of such Bond with their reasonable fees and expenses in
connection with the issuance of any such replacement Bond.

        The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, lost, stolen or destroyed Bonds.

        Section 4.16. Notice to Remarketing Agent and Rating Agencies. The
Trustee shall provide the Remarketing Agent, any Letter of Credit Issuer and
each Rating Agency then rating the Bonds, if the Bonds are then rated, with
prior written notice as early as practicable, of (i) the appointment of any
successor Trustee, Tender Agent or Remarketing Agent, (ii) any supplement or
amendment to this Indenture or the Loan Agreement, (iii) the provision of any
Letter of Credit, the expiration of any Letter of Credit, the renewal of any
Letter of Credit or the provision of an Alternate Letter of Credit, (iv) the
payment in full of all of the Bonds, (v) the giving of a notice of mandatory
tender of the Bonds, or (vi) the conversion of the Bonds to a new Rate Period.
Each notice to the Rating Agencies hereunder shall be directed to the respective
addresses provided by the Rating Agencies. The Trustee's agreement to give the
notices to the Rating Agencies provided for in this Section is made as a matter
of courtesy and accommodation only, and the Trustee shall incur no liability to
any Person for its failure to give such notices.

Issuer, but are limited obligations payable solely and only from the Revenues
received under the Loan Agreement, the documents executed by the Borrower in
connection therewith and the Funds and Accounts created pursuant to this
Indenture, and as authorized by the Refunding Law and provided herein. No
covenant or agreement contained in the Bonds, in this Indenture or in any other
agreement referred to in this Indenture shall be deemed to be the covenant or
agreement of any officer, member, agent or employee of the Issuer in his or her
individual capacity, and neither such persons nor any official executing the
Bonds shall be liable personally on the Bonds or be subject to any personal
liability or accountability by reason of the issuance thereof.

thereafter to reimburse any Letter of Credit Issuer for any amounts outstanding
under the Reimbursement Agreement, upon receipt by the Trustee from the Letter
of Credit Issuer of written notice as to the amounts owed to it under the
Reimbursement Agreement. Notwithstanding anything herein to the contrary, no
amounts contained in the Borrower Revenue Account shall be used to pay principal
of, premium, if any or interest on the Bonds so long as amounts are available to

made and shall certify that such investment constitutes a Permitted Investment
and

is otherwise permitted to be made hereunder and under the Loan Agreement
(including Section 7.5 thereof). Moneys held in the Bond Purchase Fund shall not
be invested by the Remarketing Agent or the Tender Agent. Moneys held in the
Letter of Credit Revenue Account and moneys held for the redemption of Bonds
shall be invested only in Government Obligations, which mature as needed for
payment, upon the written instructions of the Borrower, which instructions shall
specify the particular investment to be made and shall certify that such
investment constitutes a Government Obligation and is otherwise permitted to be
made hereunder. All investment instructions hereunder shall be provided to the
Trustee no later than one Business Day prior to the making of the investment
directed therein. The Trustee may make any and all such investments through its
own investment department or through any of its affiliates or subsidiaries. The
Trustee shall be entitled to rely on all written investment instructions
provided by the Borrower hereunder and shall have no duty to monitor the
compliance thereof with the restrictions set forth in this Section 5.5 and in
the Tax Certificate. The Trustee shall not be responsible or liable for the
performance of any such investments or for keeping the moneys held by it
hereunder fully invested at all times. Absent the provision of investment
instructions hereunder, the Trustee shall invest moneys held pursuant hereto in
investments described in clause (iii) of the definition of "Permitted
Investments." Any obligations acquired by the Trustee as a result of such
investment or reinvestment shall be held by or under the control of the Trustee
(except for such investments held in book entry form) and shall be deemed to
constitute a part of the Fund or Account from which the moneys used for its
purchase were taken. All investment income shall be retained in the Fund or
Account to which the investment is credited from which such income is derived,
and with respect to the Revenue Fund shall be available for the purposes set
forth in Section 5.4 hereof (and to the extent so available shall serve as a
credit against the amount due from the Borrower under Section 2.7 of the Loan
Agreement on the next succeeding Loan payment date). Any investment losses shall
be charged to the Fund or Account from which such investment was made. Monies
held under Section 4.8 shall not be invested. The Issuer (and the Borrower by
its execution of the Loan Agreement) acknowledges that to the extent regulations
of the Comptroller of the Currency or other applicable regulatory entity grant
the Issuer or the Borrower the right to receive brokerage confirmations of
security transactions as they occur, the Issuer and the Borrower specifically
waive receipt of such confirmations to the extent permitted by law. The Trustee
will furnish the Issuer and the Borrower periodic cash transaction statements
which include detail for all investment transactions made by the Trustee
hereunder. To the extent the Trustee does not receive written instructions for
investment from the Borrower, the Trustee shall invest, to the extent reasonably
practicable in investments described in clause (iii) of the definition of
"Permitted Investments."

        The Trustee may make any investments hereunder through its own bond or
investment department or trust investment department, or those of its parent or
any affiliate.

        The Trustee or any of its affiliates may act as sponsor, advisor or
manager in connection with any investments made by the Trustee hereunder.

        Section 5.6. Moneys Held in Trust. All moneys required to be deposited
with or paid to the Trustee for the account of any Fund or Account under any
provisions of this Indenture shall be held by the Trustee in trust, and, except
for moneys deposited with or paid to the Trustee for redemption of Bonds, notice
of the redemption for which has been duly given and except for moneys in the
Bond Purchase Fund and the Rebate Fund, shall, while held by the Trustee,
constitute part of the Trust Estate and be subject to the security interest
created hereby.

        Section 5.7. Repayment to Borrower from Indenture Funds. Any amounts
remaining in any Fund or Account created under this Indenture, after payment or
provision for payment in full of the Bonds in accordance with Article VI hereof,
any sums due any Letter of Credit Issuer, the fees, charges and expenses of the
Issuer, the Trustee, the Tender Agent, the Remarketing Agent and any co-trustee
appointed hereunder, and all other amounts required to be paid hereunder or
under the Loan Agreement, and after and to the extent that the Borrower shall
determine that the payment of such remaining amounts may be made without
violation of the provisions of the Tax Certificate, shall be paid, upon the
expiration of, or upon the sooner termination of, the terms of this Indenture,
to the Borrower, provided that the Borrower shall have delivered a certificate
to the Trustee to the effect that all conditions precedent to such payment set
forth in this Section have been complied with.

        Section 5.8. Tax Covenants. The Issuer covenants with the Owners of the
Bonds that, notwithstanding any other provision of this Indenture or any other
instrument, it will not make any investment or other use of the proceeds of the
Bonds or any other moneys held under this Indenture which would cause the Bonds
to be "arbitrage bonds" under Section 148 of the Code or "federally guaranteed"
obligations under Section 149 of the Code, and it further covenants that it will
comply with all applicable requirements of Sections 103 and 141-150 of the Code
(except that the Issuer shall be deemed to have complied with these requirements
as long as it acts on the written direction of the Borrower). The foregoing
covenants shall extend throughout the term of the Bonds to all Funds and
Accounts created under this Indenture and all moneys on deposit to the credit of
any such Fund or Account, and to any other amounts which are proceeds of the
Bonds or which have been replaced with proceeds of the Bonds for purposes of
Sections 103 and 141-150 of the Code. It is expressly understood that because
investments hereunder are to be made by the Trustee only pursuant to
instructions of the Borrower, the Trustee shall have no liability with respect
thereto if, as a result of an investment made pursuant to such instructions, the
Bonds become "arbitrage bonds" under Section 148 of the Code or "federally
guaranteed" obligations under Section 149 of the Code or the covenants of this
Section are otherwise violated.

        Section 5.9. Rebate Fund. There is hereby created by the Issuer and
ordered established with the Trustee a trust fund to be designated the
"California Statewide Communities Development Authority Apartment Development
Revenue Refunding Bonds, Series 1998A Rebate Fund" (the "Rebate Fund"). All
money at any time deposited in the Rebate Fund shall be held by the Trustee in
trust, to the extent required to satisfy the Rebate Requirement (as defined in
the Tax Certificate) and as calculated by the Rebate Analyst, for payment to the
United States Government, and neither the Issuer nor the Borrower nor the
Bondholders shall have any rights in or claim to such moneys. All amounts
deposited into or on deposit in the Rebate Fund shall be governed by this
Section and by the Tax Certificate. The Trustee shall conclusively be deemed to
have complied with such provisions if it follows the written instructions of the
Borrower, including supplying all necessary information in the manner set forth
in the Tax Certificate, and shall not be required to take any actions thereunder
in the absence of written instructions from the Borrower.

               Within 55 days of the end of each fifth Bond Year, the Borrower
shall or shall cause the Rebate Analyst to calculate the amount of rebatable
arbitrage, in accordance with Section 148(f)(2) of the Code and Section 1.148-3
of the Rebate Regulations (taking into account any applicable exceptions with
respect to the computation of the rebatable arbitrage, described, if applicable,
in the Tax Certificate (e.g., the temporary investments exceptions of





                                       54
<PAGE>   60

Section 148(f)(4)(B) and (C) of the Code), for this purpose treating the last
day of the applicable Bond Year as a (computation) date, within the meaning of
Section 1.148-1(b) of the Rebate Regulations (the "Rebatable Arbitrage").

               Within 55 days of the end of each fifth Bond Year, upon the
written direction of the Borrower, an amount shall be deposited to the Rebate
Fund by the Trustee from amounts provided by the Borrower, if and to the extent
required so that the balance in the Rebate Fund shall equal the amount of
Rebatable Arbitrage so calculated in accordance with the preceding paragraph.

               The Trustee shall pay, as directed by the Borrower, to the United
States Treasury, out of amounts in Rebate Fund:

               (i) Not later than 60 days after the end of (A) the fifth Bond
        Year, and (B) each applicable fifth Bond Year thereafter, an amount
        equal to at least 90% of the Rebatable Arbitrage calculated as of the
        end of such Bond Year; and

               (ii) Not later than 60 days after the payment of all the Bonds,
        an amount equal to 100% of the Rebatable Arbitrage calculated as of the
        end of such applicable Bond Year, and any income attributable to the
        Rebatable Arbitrage, computed in accordance with Section 148(f) of the
        Code.

               Each payment required to be made under this Section shall be made
to the Internal Revenue Service Center, Philadelphia, Pennsylvania 19255 on or
before the date on which such payment is due, and shall be accompanied by
Internal Revenue Service Form 8038-T, which shall be prepared by the Rebate
Analyst or the Borrower and provided to the Trustee.

               Notwithstanding any provision of this Indenture to the contrary,
the obligation to remit payment of Rebatable Arbitrage to the United States and
to comply with all other requirements of this Section 5.9 and the requirements
of the Tax Certificate shall survive the defeasance or payment in full of the
Bonds.

               Any funds remaining in the Rebate Fund after redemption and
payment of all of the Bonds and payment and satisfaction of any Rebate
Requirement, or provision made therefor satisfactory to the Trustee, shall be
withdrawn and remitted to the Borrower as provided for in Section 5.7 of this
Indenture.

               The Trustee shall keep such records of the computations made
pursuant to this Section 5.9 as are required under Section 148(f) of the Code to
the extent furnished to the Trustee. The Trustee shall keep and make available
to the Borrower such records concerning the investments of the gross proceeds of
the Bonds and the investments of earnings from those investments made by the
Trustee as may be requested by the Borrower in order to enable the Borrower to
make the aforesaid computations as are required under Section 148(f) of the
Code.

               Notwithstanding the foregoing, the computations and payments of
Rebatable Arbitrage referred to in this Section 5.9 need not be made to the
extent that neither the Issuer nor the Borrower will thereby fail to comply with
any requirements of Section 148(f) of the Code based on an opinion of Bond
Counsel, a copy of which shall be provided to the Trustee.





                                       55

               The Trustee shall not be responsible for calculating rebate
amounts or for the adequacy or correctness of any rebate report or rebate
calculations. The Trustee shall be deemed conclusively to have complied with the
provisions of this Indenture or any other agreement relating to the Bonds
regarding calculation and payment of rebate if it follows the directions of the
Borrower and it shall have no independent duty to review any such calculations
or enforce compliance with such rebate requirements.


                                   ARTICLE VI

                             DISCHARGE OF INDENTURE

        Section 6.1. Discharge. If the Issuer shall pay or cause to be paid, or
there shall be otherwise paid, or provision shall be made for the payment of,
the principal, premium, if any, and interest due or to become due on the Bonds
at the times and in the manner stipulated therein, and if the Issuer shall not
then be in default under any of the other covenants and promises in such Bonds
and this Indenture to be kept, performed and observed by it or on its part, and
if the Issuer shall pay or cause to be paid to the Trustee all sums of money due
or to become due according to the provisions hereof or of the Bonds and of the
Loan Agreement, then, except for the rights of the Trustee under Section 8.2
hereof, these presents and the interests in the Trust Estate and rights hereby
granted shall cease, determine and be void, and the Trustee shall take such
actions as may be required by the Issuer to evidence the cancellation and
discharge of the lien of this Indenture. Any Bond shall be deemed to be paid
within the meaning of this Article VI and for all purposes of this Indenture
when (i) payment of the principal of and the applicable redemption premium, if
any, on such Bond, plus interest thereon to the due date thereof (whether such
due date be by reason of maturity or upon redemption as provided in this
Indenture, or otherwise), shall have been provided to the Trustee by irrevocably
depositing with the Trustee, in trust, and the Trustee shall have irrevocably
set aside exclusively for such payment, any combination of (1) funds provided by
the Borrower sufficient to make such payment, and/or (2) Government Obligations
(purchased with such funds) not subject to redemption or prepayment and maturing
as to principal and interest in such amounts and at such times as will, in the
written opinion of a firm of nationally recognized independent certified public
accountants delivered to the Trustee, provide sufficient moneys, without
reinvestment of any matured amounts, to make such payment without reinvestment
(and there shall be no such reinvestment); (ii) the Trustee shall have been
given irrevocable written instructions to call all outstanding Bonds for
redemption on a date certain, if such Bonds are to be called for redemption
prior to maturity; (iii) the Trustee shall have received a Favorable Opinion of
Bond Counsel; and (iv) all necessary and proper fees, compensation, expenses and
indemnities of the Trustee and the Tender Agent pertaining to the Bonds shall
have been paid or the payment thereof provided for to the satisfaction of the
Trustee.

        Prior to the defeasance of Bonds in a Daily Rate or a Weekly Rate, the
Borrower shall be required to effect a conversion of the Bonds to a Flexible
Rate or a Term Rate having a term equal to or greater than the date of
redemption contained in the notice set forth in (ii) above. Prior to the
defeasance of Bonds having a Term Rate which have Term Rate Periods shorter than
the redemption date contained in the notice set forth in (ii) above, the
Borrower shall be required to effect a conversion of the Bonds to a Flexible
Rate or to a Term Rate having a term equal to or greater than the redemption
date set forth in (ii) above. Prior to the defeasance of Bonds having a Term
Rate, the





                                       56
<PAGE>   62

Trustee shall establish a redemption date for the Bonds which is on or prior to
the termination date of the Term Rate Period unless the Bonds mature at the end
of the Term Rate Period.


                                   ARTICLE VII

                         EVENTS OF DEFAULT AND REMEDIES

        Section 7.1. Events of Default. Each of the following events is hereby
defined as, and declared to constitute, an "Event of Default" under this
Indenture:

                     (i) failure to pay (a) interest on any Outstanding Bond
        when due, or (b) the principal or purchase price of, or premium, if any,
        on, any Outstanding Bond, whether at the stated maturity thereof, upon
        the purchase date thereof, upon any proceedings for redemption, or upon
        the maturity thereof or by declaration of acceleration;

                     (ii) failure by the Issuer to perform or observe any of
        the other covenants, agreements or conditions contained in this
        Indenture, and the continuation thereof for the period after notice
        specified in Section 7.12 hereof; or

                     (iii) the occurrence and continuance of an event of
        default under the Loan Agreement.

        Section 7.2. Acceleration. (A) Upon the occurrence of an Event of
Default described in Section 7.1(i), the Trustee shall accelerate the maturity
of the Bonds then Outstanding, whereupon the principal of and all accrued
interest on all of the Bonds shall become immediately due and payable, without
premium, and no interest shall accrue on any Bond from and after the date of
such acceleration. Upon the occurrence of any other Event of Default, the
Trustee may, and if requested to do so by the Owners of not less than
twenty-five percent (25%) in aggregate principal amount of the Bonds then
Outstanding, shall, accelerate the maturity of the Bonds, whereupon the
principal of and all accrued interest on the Bonds shall become immediately due
and payable, without premium, and no interest shall accrue on any Bond from and
after the date of such acceleration. In the event of any acceleration of the
Bonds, the Trustee shall give the Issuer and the Borrower written notice of the
acceleration of the Loan.

        Section 7.3. Other Remedies; Rights of Bond Owners. Subject to the next
succeeding paragraph, upon the occurrence of any Event of Default described in
Section 7.1, the Trustee shall upon the written request of the Owners of at
least twenty-five percent (25%) in aggregate principal amount of the Bonds
outstanding and upon receipt of an indemnity satisfactory to the Trustee, pursue
any available remedy by suit at law or in equity to enforce the payment of the
principal or purchase price of, premium, if any, and interest on the Bonds then
Outstanding, and the performance by the Issuer of its obligations hereunder,
including, without limitation, the following:

                     (i) by mandamus, or other suit, action or proceeding at law
        or in equity, enforce all rights of the Bond Owners, and require the
        Issuer to carry out its obligations under this Indenture;

                     (ii) bring suit upon the Bonds;





                                       57
<PAGE>   63

                     (iii) by action, suit or proceeding at law or in equity
        require the Issuer to account for any moneys received by the Issuer as
        if it were the trustee of an express trust for the Bond Owners; and

                     (iv) by action, suit or proceeding at law or in equity,
        specifically enforce the provisions of the Loan Agreement or enjoin any
        acts or things which may be unlawful or in violation of the rights of
        the Bond Owners under this Indenture.

Any judgment against the Issuer shall be enforceable only against the Trust
Estate. There shall not be authorized any deficiency judgment against any assets
of, or the general credit of, the Issuer. Subject to the prior rights of the
Bond Owners, the Issuer shall be entitled to reimbursement for any of its
expenses in connection with such proceeding from any available funds in the
Trust Estate.

        If an Event of Default shall have occurred and is continuing, and if
requested to do so by the Owners of not less than twenty-five percent (25%) in
aggregate principal amount of the Bonds then Outstanding, and if indemnified as
provided in Section 8.1(l) hereof, the Trustee shall be obligated (subject to
Section 7.4 hereof) to exercise one or more of the rights and powers conferred
by this Section 7.3 or by Section 7.2 hereof as the Trustee, being advised by
counsel, shall deem most expedient in the interests of the Bond Owners.

        No remedy conferred upon or reserved to the Trustee or the Bond Owners
by the terms of this Indenture is intended to be exclusive of any other remedy,
but each and every such remedy shall be cumulative and shall be in addition to
any other remedy given to the Trustee or the Bond Owners hereunder or now or
hereafter existing at law or in equity. No delay or omission to exercise any
right or power accruing upon any default or Event of Default shall impair any
such right or power or shall be construed to be a waiver of any such default or
Event of Default or an acquiescence therein; and every such right and power may
be exercised from time to time as often as may be deemed expedient. No waiver of
any default or Event of Default hereunder, whether by the Trustee or the Bond
Owners, shall extend to or shall affect any subsequent default or Event of
Default or shall impair any right or remedy consequent thereon.

        The above provisions, however, are subject to the condition that if,
after the principal of all the Bonds then Outstanding shall have been so
declared to be due and payable and prior to the entry of a judgment or decree
for the payment of any moneys due pursuant to the Bonds, this Indenture or the
Loan Agreement, all accrued and unpaid interest on the Bonds, at the applicable
rate per annum borne by the Bonds at the time of acceleration, and all other
sums payable under this Indenture, except the principal of, and interest on, the
Bonds which by such declaration shall have become due and payable, shall have
been paid by or on behalf of the Issuer, all other Events of Default hereunder
shall have been cured or waived, and the Issuer also shall have performed all
other things in respect of which it may have been in default under this
Indenture, and shall have paid the reasonable fees and expenses of the Trustee
and of the Owners of the Bonds, including reasonable attorneys' fees paid or
incurred then and in every such case, the Owners of not less than a majority in
aggregate principal amount of the Bonds then Outstanding, by written notice to
the Trustee may rescind and annul such declaration, whereupon the Trustee shall
give written notice thereof to the Issuer and the Borrower by registered mail.
Any such rescission and annulment shall be binding upon all holders of the
Bonds, but no such rescission and annulment shall extend to or affect any
subsequent default or impair any right or remedy consequent thereon.





                                       58
<PAGE>   64

        Section 7.4. Right of Bond Owners to Direct Proceedings. Anything in
this Indenture to the contrary notwithstanding, upon the occurrence and
continuance of an Event of Default, the Owners of a majority in aggregate
principal amount of the Bonds then Outstanding shall have the right, at any
time, by an instrument or instruments in writing executed and delivered to the
Trustee, to direct the method and place of conducting all proceedings to be
taken in connection with the enforcement of the terms and conditions of this
Indenture, or for the appointment of a receiver or for any other proceedings
hereunder; provided, however, that direction shall not be otherwise than in
accordance with the provisions of law and of this Indenture and shall not
involve the Trustee in personal liability.

        Section 7.5. Appointment of Receiver. Upon the occurrence and
continuance of an Event of Default, and upon the filing of a suit or other
commencement of judicial proceedings to enforce the rights of the Trustee and
the Bond Owners under this Indenture, the Trustee shall be entitled, as a matter
of right, to request the appointment of a receiver or receivers of the Trust
Estate and of the revenues, issues, earnings, income, products and profits
thereof, pending such proceedings, with such powers as the court making such
appointment shall confer.

        Section 7.6. Waiver of Certain Laws. Upon the occurrence of an Event of
Default, to the extent that such rights may then lawfully be waived, neither the
Issuer, nor anyone claiming through or under it, shall claim or seek to take
advantage of any appraisement, valuation, stay, extension or redemption laws now
or hereafter in force, in order to prevent or hinder the enforcement of this
Indenture. The Issuer, for itself and all who may claim through or under it,
hereby waives, to the extent that it lawfully may do so, the benefit of all such
laws.

        Section 7.7. Application of Moneys. All moneys relating to the Bonds
received by the Trustee pursuant to any right given or action taken under the
provisions of this Article VII shall (after payment of the costs and expenses
(including legal fees and expenses) of the proceedings resulting in the
collection of such moneys and of the fees and expenses, liabilities and advances
of the Issuer, the Trustee and the Tender Agent, it being understood that such
payment shall not be made from any moneys already held for the benefit of the
Bond Owners in the Bond Purchase Fund or the Letter of Credit Revenue Account or
pursuant to Section 4.8) be deposited in the Accounts of the Revenue Fund as
required under Section 5.3 hereof, and all moneys in such Accounts shall be
applied as required under Section 5.4 hereof as follows:

                     (i) Unless the principal of all the Bonds Outstanding shall
        have become or shall have been declared due and payable, all such moneys
        shall be applied:

                     FIRST - To the payment to the persons entitled thereto of
               all installments of interest then due on the Outstanding Bonds
               and, if the amount available shall not be sufficient to pay in
               full any particular installment, then to the payment ratably,
               according to the amounts due on such installment, to the persons
               entitled thereto, without any discrimination or privilege; and

                     SECOND - To the payment to the persons entitled thereto of
               the unpaid principal of, and premium, if any, on, the Outstanding
               Bonds which shall have become due (other than Bonds matured or
               called for redemption for the payment of which moneys are already
               held pursuant to the provisions of this Indenture) in the




                                       59
<PAGE>   65

               order of their due dates, and, if the amount available shall not
               be sufficient to pay in full the principal of each Bond due on
               any particular date, together with such premium, then to the
               payment ratably, according to the amount of principal and premium
               due on such date, to the persons entitled thereto, without any
               discrimination or privilege.

                     (ii) If the principal of all the Outstanding Bonds shall
        have become due or shall have been declared due and payable by
        acceleration, all such moneys shall be applied to the payment of the
        principal, premium, if any, and interest then due on such Bonds, without
        preference or priority of principal and premium over interest or of
        interest over principal and premium, or of any installment of interest
        over any other installment of interest, or of any Bond over any other
        Bond, ratably, according to the amounts due respectively for principal,
        premium, if any, and interest, to the persons entitled thereto, without
        any discrimination or privilege.

                     (iii) If the principal of all the Outstanding Bonds shall
        have been declared due and payable by acceleration, and if such
        declaration shall thereafter have been rescinded and annulled under the
        provisions of this Article VII, then the moneys shall be applied in
        accordance with the provisions of subsection (i) above; provided,
        however, that in the event that the principal of all the Bonds shall
        later become due or be declared due and payable by acceleration, the
        moneys shall be applied in accordance with the provisions of subsection
        (ii) above.

Whenever moneys are to be applied pursuant to the provisions of this Section
7.7, such moneys shall be applied at such times, and from time to time, as the
Trustee shall determine is appropriate upon due consideration of the amount of
such moneys available for application and the likelihood of additional moneys
becoming available for such application in the future.

        Whenever the Trustee shall apply such funds it shall fix the date of
application, which shall be an Interest Payment Date unless it shall deem, in
the reasonable exercise of its discretion, another date more suitable. The
Trustee shall give such notice as it may deem appropriate of the deposit with it
of any such moneys and of the fixing of any such date.

        For purposes of this Section, the term "principal" shall include the
principal component of the purchase price of the Bonds, and the term "interest"
shall include the interest component of the purchase price of the Bonds.

        Section 7.8. Remedies Vested in Trustee. All rights of action (including
the right to file proofs of claim) under this Indenture and under the Bonds or
any Bond may be enforced by the Trustee without the possession of any Bond or
the production thereof in any trial or proceedings related thereto, and any such
suit or proceeding instituted by the Trustee shall be brought in its name as
Trustee without the necessity of joining as plaintiff or defendant the Owner of
any Bond.

        Section 7.9. Rights and Remedies of Bond Owners. No Owner of any Bond
shall have any right to institute any suit, action or proceeding in equity or at
law for the enforcement of this Indenture or for the execution of any trust
hereof or for the appointment of a receiver or any other remedy hereunder,
unless:

                     (i) an Event of Default has occurred of which the Trustee
        has been notified as provided in Section 8.1(h) hereof, or of which by
        said Section 8.1(h) the Trustee is deemed to have notice;

                     (ii) the Owners of not less than twenty-five percent (25%)
        in aggregate principal amount of the Bonds then Outstanding shall have
        made written request to the Trustee, and shall have offered the Trustee
        reasonable opportunity either to proceed to exercise the powers
        hereinbefore granted or to institute such action, suit or proceeding in
        the name or names of such Owners, and shall have offered to the Trustee
        indemnity as provided in Section 8.1(l) hereof; and

                     (iii) the Trustee shall thereafter fail or refuse to
        exercise the powers hereinbefore granted, or to institute such action,
        suit or proceeding in its own name, within 60 days;

and such notification, request and offer of indemnity are hereby declared in
every case, at the option of the Trustee, to be conditions precedent to the
execution of the powers and trusts of this Indenture (other than its obligations
to draw under any Letter of Credit as required to make payments of principal of,
premium, if any, and interest on the Bonds when due), and to any action or cause
of action for the enforcement of this Indenture, or for the appointment of a
receiver or for any other remedy hereunder. No one or more Owners of the Bonds
shall have any right in any manner whatsoever to affect, disturb or prejudice
the lien of this Indenture by such Owners' action, and all proceedings at law or
in equity shall be instituted, had and maintained in the manner herein provided
and (except as herein otherwise provided) for the equal and ratable benefit of
the Owners of all Bonds then Outstanding. Nothing in this Indenture, however,
shall affect or impair the right of any Bond Owner to enforce the payment of the
principal of, premium, if any, and interest on any Bond owned by such Bond Owner
at and after the maturity thereof, or the obligation of the Issuer to pay the
principal of, premium, if any, and interest on any Bond to the Owner thereof at
the time and place, from the source, and in the manner expressed in such Bond.
Nothing contained herein shall be construed as permitting or affording any Bond
Owner a right or cause of action against the Trustee or in respect of the Bonds
where a default has been waived under Section 7.11 hereof or cured under Section
7.12 hereof.

        Section 7.10. Termination of Proceedings. In case the Trustee shall have
proceeded to enforce any right under this Indenture by the appointment of a
receiver or otherwise, and such proceedings shall have been discontinued or
abandoned for any reason, or shall have been determined adversely to the
Trustee, then and in every such case the Issuer, the Trustee and the Bond Owners
shall be restored to their former positions and rights hereunder, and all
rights, remedies and powers of the Trustee shall continue as if no such
proceedings had been taken.

        Section 7.11. Waivers of Events of Default. The Trustee may in its
discretion waive any Event of Default hereunder and its consequences, and shall
do so upon the written request of the Owners of a majority in aggregate
principal amount of the Bonds then Outstanding; provided, however, that the
Trustee may not waive an Event of Default described in subparagraph (i) of
Section 7.1 hereof without the consent of the registered Owners of all Bonds
then Outstanding.

        Section 7.12. Notice of Default; Opportunity to Cure Defaults. Anything
herein to the contrary notwithstanding, no failure to act under Section 7.1(ii)
hereof shall constitute an Event of Default until actual notice of such failure
by registered or certified mail shall be given to the Issuer and the Borrower by
the Trustee, or to the Issuer, the Borrower and the Trustee by the Owners of not
less than twenty-five percent (25%) in aggregate principal amount of all Bonds
Outstanding, any such notice to specify the failure, require it to be remedied
and to state that such notice is a "Notice of Default" hereunder, and the Issuer
and the Borrower shall have had sixty (60) days after receipt of such notice at
their option to correct such failure or to cause such failure to be corrected,
and shall not have corrected such failure or caused such failure to be corrected
within the applicable period; provided, however, that if such failure be such
that it cannot be corrected within the applicable period, it shall not
constitute an Event of Default if corrective action is instituted by the Issuer
and the Borrower, or either of them, within the applicable period and diligently
pursued until the default is corrected.

        With regard to any failure to act for which notice is given under the
provisions of this Section 7.12, the Issuer, to the full extent permitted by
law, hereby grants the Borrower full authority to perform and observe for the
account of the Issuer any covenant or obligation alleged in said notice not to
have been performed or observed in the name and stead of the Issuer with full
power to do any and all things and acts to the same extent that the Issuer could
do and perform any such things and acts, with power of substitution.


                                  ARTICLE VIII

                 THE TRUSTEE, TENDER AGENT AND REMARKETING AGENT

        Section 8.1. Acceptance of Trusts. The Trustee hereby accepts the trusts
imposed upon it by this Indenture, and agrees to perform said trusts, but only
upon and subject to the following express terms and conditions:

               (a) The Trustee, prior to the occurrence of an Event of Default
        and after the curing or waiving of all Events of Default which may have
        occurred, undertakes to perform such duties and only such duties as are
        specifically set forth in this Indenture and no implied covenants or
        obligations shall be read into this Indenture against the Trustee. In
        case an Event of Default has occurred (which has not been cured or
        waived), the Trustee shall exercise such of the rights and powers vested
        in it by this Indenture, and use the same degree of care and skill in
        their exercise, as a prudent person would exercise or use under the
        circumstances in the conduct of such person's affairs.

               (b) The Trustee may execute any of the rights or powers hereunder
        or perform any duties hereunder either directly or by or through agents,
        receivers or attorneys and the Trustee shall not be responsible for the
        acts of such agents, receivers or attorneys if selected





                                       62
<PAGE>   68

        and appointed by the Trustee with due care; provided that any such
        agents or attorneys shall be responsible for their acts to the same
        extent as the Trustee would have been responsible had the Trustee
        performed such acts itself. The Remarketing Agent shall not be deemed an
        agent of the Trustee for any purpose, and the Trustee shall not be
        responsible for the compliance of the Remarketing Agent with its
        obligations under this Indenture or in connection with the transactions
        contemplated herein. The Trustee shall be entitled to the advice of
        counsel (which may be an employee of the Trustee or an affiliate of the
        Trustee) concerning all matters of trust hereof and its duties
        hereunder, and in all cases may pay such reasonable compensation to all
        such attorneys, agents, receivers and employees as may reasonably be
        employed in connection with the trust hereof. The Trustee may act upon
        the opinion or advice of any attorneys approved by the Trustee in the
        exercise of reasonable care. The Trustee shall not be responsible for
        any loss or damage resulting from any action or non-action exercised in
        good faith in reliance upon such opinion or advice.

               (c) The Trustee shall not be responsible for any recital herein
        or in the Bonds (other than the certificate of authentication thereon),
        the legality, sufficiency or validity of this Indenture, the Loan
        Agreement, the Bonds or any document or instrument relating hereto or
        thereto; the recording or filing of any instrument required by this
        Indenture to secure the Bonds; the validity of the execution by the
        Issuer of this Indenture or of any supplement hereto or amendment hereof
        or of any instrument of further assurance; or the validity, priority,
        perfection or sufficiency of the security for the Bonds issued hereunder
        or intended to be secured hereby, or otherwise as to the maintenance of
        the security hereof.

               (d) The Trustee shall not be accountable for the use of any Bonds
        authenticated or delivered hereunder. The Trustee may in good faith buy,
        sell, own and hold any of the Bonds (or beneficial interests therein)
        and may join in any action which any Bond Owner may be entitled to take
        with like effect as if the Trustee were not a party to this Indenture.
        The Trustee may also engage in or be interested in any financial or
        other transaction with the Issuer, the Tender Agent, the Remarketing
        Agent, any Letter of Credit Issuer or the Borrower; provided, however,
        that if the Trustee determines that any such relationship is in conflict
        with its duties under this Indenture, it shall eliminate the conflict or
        resign as Trustee. To the extent permitted by law, the Trustee may also
        purchase Bonds (or beneficial interests therein) with like effect as if
        it were not the Trustee.

               (e) The Trustee shall be protected in acting upon, and may
        conclusively rely upon, any notice, request or other paper or document
        reasonably believed by it to be genuine and correct, and reasonably
        believed by it to have been signed or sent by the proper person or
        persons. Any action taken by the Trustee pursuant to this Indenture or
        the Loan Agreement upon the request, authority or consent of any person,
        who at the time of making such request or giving such authority or
        consent is the Owner of any Bond, shall be conclusive and binding upon
        all future Owners of the same Bond and any Bond issued in replacement
        therefor.

               (f) As to the existence or nonexistence of any fact, or as to the
        sufficiency or validity of any instrument, paper or proceeding, the
        Trustee shall be entitled to rely upon a certificate signed by a duly
        authorized representative of the Issuer, the Tender Agent, the
        Remarketing Agent or the Borrower as sufficient evidence of the facts
        therein contained; and





                                       63
<PAGE>   69

        prior to the occurrence of a default of which the Trustee has been
        notified as provided in subsection (h) of this Section 8.1, or of which
        by said subsection (h) it is deemed to have notice, the Trustee shall
        also be at liberty to accept a similar certificate to the effect that
        any particular dealing, transaction or action is necessary or expedient.
        The Trustee may, at its discretion, secure such further evidence
        (including, but not limited to, legal opinions) deemed necessary or
        advisable by it, but shall in no case be bound to secure the same. The
        Trustee may accept a certificate of the officer of the Issuer charged
        with the maintenance of its books and records over the seal of the
        Issuer to the effect that a resolution or ordinance in the form therein
        set forth has been adopted and is in full force and effect.

               (g) The right of the Trustee to perform any discretionary act
        enumerated in this Indenture shall not be construed as a duty. No
        provision of this Indenture shall be construed to relieve the Trustee
        from liability for its negligence or willful misconduct in the
        performance of its powers and duties under this Indenture, except that

                   (i) this subsection shall not be construed to limit the
               effect of subsection (a) of this Section;

                   (ii) in the absence of bad faith on its part, the Trustee may
               conclusively rely, as to the truth of the statements and the
               correctness of the opinions expressed therein, upon certificates
               or opinions furnished to the Trustee and conforming to the
               requirements of this Indenture or the Loan Agreement, as the case
               may be;

                   (iii) the Trustee shall not be liable for any error of
               judgment made in good faith by its officers, unless it shall be
               proved that the Trustee was negligent in ascertaining the
               pertinent facts;

                   (iv) the Trustee shall not be liable with respect to any
               action taken or omitted to be taken by it in good faith in
               accordance with any direction of Bond Owners given pursuant to
               Section 7.4; and

                   (v) no provision of this Indenture shall be deemed to require
               the Trustee to expend or risk its own funds or otherwise incur
               any financial liability in the performance of any of its duties
               hereunder, or in the exercise of its rights or powers.

               (h) The Trustee shall not be required to take notice or be deemed
        to have notice of any default or Event of Default hereunder or under the
        Loan Agreement, or in any other document or instrument executed in
        connection with the execution and delivery of the Bonds, except an Event
        of Default under Section 7.1(i) hereof, unless the Trustee shall be
        specifically notified in writing of such default or Event of Default by
        the Issuer, the Tender Agent, the Borrower or the Owners of at least
        twenty-five percent (25%) in aggregate principal amount of the Bonds
        then Outstanding. All notices or other instruments required by this
        Indenture to be delivered to the Trustee shall be delivered at the
        Principal Office of the Trustee, and, in the absence of such notice so
        delivered, the Trustee may conclusively assume there is no default or
        Event of Default except as aforesaid.





                                       64
<PAGE>   70

               (i) At any and all reasonable times, and upon prior notice, the
        Trustee and its duly authorized agents, attorneys, experts, engineers,
        accountants and representatives shall have the right (but not any duty)
        to inspect fully all books, papers and records of the Issuer pertaining
        to this Indenture, the Loan Agreement, the Tax Certificate and the
        Bonds, and to take such photocopies and memoranda therefrom and in
        regard thereto as may be desired.

               (j) The Trustee shall not be required to give any bond or surety
        in respect of the execution of the trust created hereby or the powers
        granted hereunder.

               (k) Notwithstanding anything contained elsewhere in this
        Indenture to the contrary, the Trustee shall have the right, but not the
        obligation, to demand, in respect of the withdrawal of any cash, the
        release of any property, or the taking of any action whatsoever within
        the purview of this Indenture or the Loan Agreement, any showing,
        certificate, opinion, appraisal or other information, or corporate
        action or evidence thereof, in addition to that required by the terms
        hereof as a condition of such action by the Trustee, as deemed desirable
        for the purposes of establishing the right of the Issuer or the Borrower
        to the withdrawal of any cash, the release of any property or the taking
        of any other action by the Trustee.

               (l) Before taking any action referred to in Article VII or
        Section 8.3 hereof (except with respect to acceleration of the Bonds,
        payment of the Bonds upon such acceleration or their due date or
        requests for payment under any Letter of Credit) the Trustee may require
        that a satisfactory indemnity bond be furnished for the reimbursement of
        all expenses which it may incur and to protect it against all liability,
        except liability which is adjudicated to have resulted from its
        negligence or willful misconduct, by reason of any action so taken.

               (m) All moneys received by the Trustee shall, until used, applied
        or invested as herein provided, be held in trust for the purposes for
        which they were received, but need not be segregated from other funds,
        except to the extent required by law or this Indenture. The Trustee
        shall be under no liability for interest on any moneys received by it
        hereunder.

               (n) Notwithstanding the effective date of this Indenture or
        anything to the contrary in this Indenture, the Trustee shall have no
        liability or responsibility for any act or event relating to this
        Indenture which occurs prior to the date the Trustee formally executes
        this Indenture and commences acting as Trustee hereunder.

               (o) The Trustee has no obligation or liability to the Bond Owners
        for the payment of interest or premium, if any, on, or principal or
        purchase price of, the Bonds, but rather the Trustee's sole obligations
        are to administer, for the benefit of the Borrower and the Bond Owners,
        the various Funds and Accounts established hereunder.

               (p) Notwithstanding the final payment of the principal of or
        interest on the Bonds, whether at maturity, upon redemption or
        otherwise, the duties of the Trustee under Section 5.9 of this Indenture
        shall survive the termination of this Indenture.





                                       65
<PAGE>   71

               (q) Any request or direction of the Issuer, any Letter of Credit
        Issuer or the Borrower mentioned herein or in the Loan Agreement shall
        be sufficiently evidenced by a writing signed by any authorized officer
        thereof.

               (r) The Trustee shall have no responsibility with respect to any
        information, statement, or recital in any official statement, offering
        memorandum or any other disclosure material prepared or distributed with
        respect to the Bonds.

               (s) The Trustee and the Tender Agent may rely upon any
        representation that a party is a Beneficial Owner or a Direct
        Participant for purposes of this Indenture.

               (t) The Tender Agent shall be entitled to the same protections,
        immunities and limitations from liability afforded the Trustee
        hereunder.

               (u) The Trustee is authorized and directed in its capacity as
        Trustee to enter into the Loan Agreement, the Regulatory Agreements and
        the Redemption Agreement.

        Section 8.2. Annual Fees, Charges and Expenses of Trustee and Tender
Agent. The Trustee and the Tender Agent shall be entitled to reasonable
compensation for all services, including any extraordinary services, rendered by
them under this Indenture. In addition, the Trustee and the Tender Agent shall
be entitled to reimbursement for their charges and expenses (including
reasonable counsel fees and expenses) incurred in connection with such services
and to indemnity against losses, liabilities and expenses. Such compensation,
reimbursement and indemnity shall be paid by the Borrower pursuant to Section
9.3 of the Loan Agreement; provided, however, that to the extent not so paid,
the Trustee may make disbursements from the Borrower Revenue Account of the
Revenue Fund to pay such amounts. The Trustee's and the Tender Agent's right to
receive compensation, reimbursement of expenses and indemnity under this Section
8.2 and under the applicable provisions of the Loan Agreement shall be secured
by a prior lien upon the Trust Estate (excluding that portion of the Trust
Estate consisting of funds received from drawings under a Letter of Credit and
funds already held for the benefit of particular Bond Owners pursuant to any
other provisions of this Indenture, as to which such lien shall be subordinate
to the lien created hereby for the benefit of the Bond Owners). The Issuer has
required the Borrower, pursuant to the Loan Agreement, to indemnify and hold
harmless the Trustee and the Tender Agent against any liabilities which the
Trustee and the Tender Agent may incur in the exercise and performance of their
powers and duties hereunder and under any other agreement referred to herein
which are not due to the Trustee's or the Tender Agent's negligence or willful
misconduct, and for any fees and expenses of the Trustee and the Tender Agent to
the extent funds are not available under this Indenture for the payment thereof.
The rights of the Trustee and the Tender Agent under this Section 8.2 shall
survive the payment in full of the Bonds and the discharge of this Indenture.

        Section 8.3. Notice to Bond Owners of Default. If a default occurs of
which the Trustee is required by Section 8.1(h) hereof to take notice or of
which notice of default is given as provided in Section 8.1(h) hereof, then the
Trustee shall promptly give written notice thereof by first class mail, postage
prepaid, to each Owner of Bonds then Outstanding. The Trustee shall promptly
give written notice to the Remarketing Agent, the Issuer, any Letter of Credit
Issuer, the Rating Agency (subject to the last sentence of Section 4.16) and the
Borrower by certified mail of any such notice of default sent to any Owner of
Bonds as provided hereunder.





                                       66
<PAGE>   72

        Section 8.4. Intervention by Trustee. In any judicial proceeding to
which the Issuer or the Borrower is a party, and which, in the opinion of the
Trustee and its counsel, has a substantial bearing on the interests of the
Owners of the Outstanding Bonds, the Trustee may intervene on behalf of the
Owners of the Bonds and shall do so if requested in writing by the Owners of at
least twenty-five percent (25%) in aggregate principal amount of the Bonds then
Outstanding, and when provided with sufficient indemnity pursuant to Section
8.1(l) hereof.

        Section 8.5. Successor Trustee by Merger or Otherwise. Any corporation
or association into which the Trustee may be converted or merged, with which it
may be consolidated, or to which it may sell or transfer its trust business and
assets as a whole or substantially as a whole, or any corporation or association
resulting from any such conversion, sale, merger, consolidation or transfer to
which it is a party, ipso facto, shall be and become the Trustee hereunder
vested with all of the title to the Trust Estate and all the trusts, powers,
discretions, immunities, privileges, responsibilities, obligations and all other
matters as was its predecessor, without the execution or filing of any
instrument or any further act, deed or conveyance on the part of any of the
parties hereto, anything herein to the contrary notwithstanding; provided,
however, that such successor Trustee meets the requirements of Section 8.14(a)
hereof.

        Section 8.6. Resignation by Trustee. The Trustee may resign from the
trusts hereby created by giving written notice to the Issuer, the Borrower, any
Letter of Credit Issuer, the Tender Agent, the Remarketing Agent and the Owners
of the Bonds then Outstanding, and shall so resign whenever it ceases to be
qualified to act as Trustee hereunder. Such notice shall be sent by certified
mail, postage prepaid, to the Bond Owners. Such resignation shall take effect
only upon the appointment of a successor Trustee. If no successor Trustee is
appointed pursuant to Section 8.8 hereof within thirty (30) days after the
delivery of such notice, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

        Section 8.7. Removal of Trustee. The Trustee may be removed at any time
by the Borrower, so long as no event of default has occurred and is continuing
under the Loan Agreement, by the Issuer, or, if the Issuer is in default
hereunder, by an instrument or substantially concurrent instruments in writing
delivered to the Issuer, the Trustee, the Tender Agent, the Remarketing Agent
and signed by the holders of more than fifty percent (50%) in aggregate
principal amount of the Bonds outstanding. Such removal shall take effect only
upon the appointment of a successor Trustee.

        Section 8.8. Appointment of Successor Trustee. In case the Trustee shall
resign, be removed, be dissolved, be in the course of dissolution or liquidation
or otherwise become incapable of acting or not be qualified to act hereunder, or
in case the Trustee shall be taken under the control of any public officer or
officers or a receiver appointed by a court, a successor may be appointed by the
Issuer, with the consent of the Borrower, and notice to the Remarketing Agent,
the Tender Agent and the Bond Owners. Such notice shall be sent by first class
mail, postage prepaid, to the Bond Owners.

        Section 8.9. Successor Trustee. Every successor Trustee appointed
hereunder shall execute, acknowledge and deliver to its predecessor, the Tender
Agent, the Remarketing Agent, the Borrower, any Letter of Credit Issuer and the
Issuer an instrument in writing accepting such appointment hereunder, and
thereupon such successor, without any further act, deed or conveyance,





                                       67
<PAGE>   73

shall become fully vested with the title to the Trust Estate and all of the
trust powers, discretions, immunities, privileges, responsibilities, obligations
and all other matters of its predecessor; but such predecessor shall,
nevertheless, on the written request of the Issuer, or of its successor Trustee,
execute and deliver an instrument transferring to such successor Trustee all the
estates, properties, rights, powers and trusts of such predecessor hereunder;
and every predecessor Trustee shall, upon payment of its charges, deliver all
securities and moneys held by it as the Trustee hereunder to its successor
Trustee. Should any instrument in writing from the Issuer be required by any
successor Trustee for more fully and certainly vesting in such successor the
estates, rights, powers and duties hereby vested or intended to be vested in the
predecessor any and all such instruments in writing shall, on request, be
executed, acknowledged and delivered by the Issuer. The resignation of any
Trustee and the instrument or instruments removing any Trustee and appointing a
successor hereunder, together with all other instruments provided for in this
Article VIII, shall be filed and/or recorded by the successor Trustee in each
recording office where this Indenture shall have been filed and/or recorded. No
appointment of a successor Trustee hereunder shall become effective unless such
successor meets the requirements of Section 8.14(a) hereof.

        Section 8.10. Appointment of Tender Agent. (a) The initial Tender Agent
hereunder shall be U.S. Bank Trust National Association. The Tender Agent shall
have power to act (i) in the authentication and delivery of Bonds in connection
with transfers and exchanges, and (ii) in effecting purchases and sales of Bonds
pursuant hereto, receiving notices of tender for purchase, making deliveries of
Bonds and holding Bonds pursuant hereto. For all purposes of this Indenture, the
authentication and delivery of Bonds by the Tender Agent shall be deemed to be
the authentication and delivery of Bonds "by the Trustee."

        (b) Any successor corporation or association to the initial Tender Agent
is otherwise eligible under this Section to act as Tender Agent, without the
execution or filing of any document or any further act on the part of the
parties hereto, the Tender Agent or such successor corporation or association;
provided, however, that such successor corporation or association meets the
requirements of paragraph (c) below.

        (c) The Tender Agent may at any time resign by giving thirty (30) days'
written notice of resignation to the Trustee, any Letter of Credit Issuer, the
Borrower, the Remarketing Agent and the Issuer, and by mailing notice of such
resignation by first class mail to the registered owners of the Bonds. The
Borrower may at any time terminate the agency of any Tender Agent by giving
written notice of termination to such Tender Agent, the Trustee, any Letter of
Credit Issuer, the Remarketing Agent and the Issuer, and by mailing notice of
such termination by certified mail to the registered owners of the Bonds. Such
resignation or termination shall take effect only upon the Trustee's assumption
of the duties of the Tender Agent or upon the appointment by the Trustee, upon
the direction of the Borrower, of a successor Tender Agent, and the acceptance
by the successor Tender Agent of such appointment. Any successor to the Tender
Agent (i) shall at all times be a commercial bank or trust company, (ii) shall
at all times be organized and doing business under the laws of the United States
or of any state, (iii) shall have a combined capital and surplus of at least
$50,000,000, (iv) shall be authorized under such laws to exercise corporate
trust powers, (v) shall be subject to supervision or examination by federal or
state authority, and (vi) shall have a rating at least "Baa3" or "P-3" by
Moody's (or Moody's shall have provided written evidence that such successor is
otherwise acceptable to Moody's) if the Bonds are then rated by Moody's and at
least "BBB-" or "A-3" by Standard & Poor's (or Standard & Poor's shall have
provided written evidence 





                                       68
<PAGE>   74
that such successor is otherwise acceptable to Standard & Poor's) if the Bonds
are then rated by Standard & Poor's . If such successor Tender Agent publishes
reports of condition at least annually pursuant to law or the requirements of
federal or state authority, then for the purposes of this Section, the combined
capital and surplus of such successor Tender Agent shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any successor Tender Agent shall cease to be
eligible under this Section, the Trustee shall either assume the duties of the
Tender Agent, or the Trustee shall appoint a successor Tender Agent upon the
direction of the Borrower; and in such event the Trustee shall give written
notice of such assumption or appointment to the Issuer, the Borrower, any Letter
of Credit Issuer and the Remarketing Agent, and shall mail notice of such
assumption or appointment by certified mail to all registered owners of the
Bonds. The Trustee agrees to furnish to the Tender Agent and the Rating Agencies
(subject to the final sentence of Section 4.16), if the Bonds are rated, a copy
of all notices sent to, or delivered by, it under this Section. The Tender Agent
shall be entitled to all exculpations and indemnifications granted to the
Trustee, as applicable, pursuant to this Article VIII.

        Section 8.11. Remarketing Agent. The Borrower shall appoint a
Remarketing Agent for the Bonds at least 90 days prior to the end of the initial
Term Rate Periods.

        Section 8.12. Qualifications of Successor Remarketing Agents;
Resignation or Removal of Remarketing Agents. (a) Each successor Remarketing
Agent shall be (i) an institution rated at least "Baa3" or "P-3" by Moody's (or
Moody's shall have provided written evidence that such successor Remarketing
Agent is otherwise acceptable to Moody's) if the Bonds are then rated by
Moody's, and at least "BBB-" or "A-3" by Standard & Poor's (or Standard & Poor's
shall have provided written evidence that such successor Remarketing Agent is
otherwise acceptable to Standard & Poor's) if the Bonds are then rated by
Standard & Poor's, (ii) acceptable to any Letter of Credit Issuer, and (iii)
authorized by law to perform all the duties imposed upon it by this Indenture.
So long as the Bonds are held in a book-entry only system, each successor
Remarketing Agent shall be the sole participant in such system with respect to
the Bonds.

        (b) A Remarketing Agent (whether initial or successor) may at any time
resign and be discharged of the duties and obligations created by this Indenture
by giving at least thirty (30) days' written notice to the Issuer, the Borrower,
any Letter of Credit Issuer, the Tender Agent and the Trustee (with a copy
thereof mailed by certified mail to each of the Bond Owners). A Remarketing
Agent (whether initial or successor) may be removed at any time by an instrument
signed by the Borrower, and filed, at least thirty (30) days prior to such
removal, with the Remarketing Agent, any Letter of Credit Issuer, the Issuer and
with the Trustee. No removal or resignation hereunder shall become effective
prior to the earlier to occur of (i) acceptance of appointment of a successor
Remarketing Agent hereunder, or (ii) thirty (30) days from the date of the
notices described in this Section.

        Section 8.13. Appointment of Separate or Co-Trustee. It is the intent of
the parties to this Indenture that there shall be no violations of any law of
any jurisdiction (including particularly the laws of the State) denying or
restricting the rights of banking corporations or associations to transact
business as a trustee in such jurisdiction. It is recognized that in case of
litigation under this Indenture, and in particular in the case of the
enforcement of this Indenture on default, or in case the Trustee deems that by
reason of any present or future law of any jurisdiction it may not exercise any





                                       69
<PAGE>   75

of the powers, rights or remedies herein granted to the Trustee, or hold title
to the properties, in trust, as herein granted, or take any other action which
may be desirable or necessary in connection therewith, it may be necessary that
the Trustee appoint an additional individual or institution as a separate
trustee or co-trustee. The following provisions of this Section 8.13 are adapted
to these ends.

        If the Trustee appoints an additional individual or institution as a
separate trustee or co-trustee to exercise such powers, rights or remedies, to
hold such title or to take such action, each and every remedy, power, right,
claim, demand, cause of action, immunity, estate, duty, obligation, title,
interest and lien expressed or intended by this Indenture to be exercised by,
vested in or conveyed to the Trustee with respect thereto shall be exercisable
by, vested in and conveyed to such separate trustee or co-trustee, but only to
the extent necessary to enable such separate trustee or co-trustee to exercise
such powers, rights and remedies, to hold such title or to take such action and
every covenant and obligation necessary for the exercise thereby by such
separate trustee or co-trustee shall run to and be enforceable by either of
them.

        Should any instrument in writing from the Issuer be required by the
separate trustee or co-trustee so appointed by the Trustee for more fully
vesting in and confirming to them such properties, rights, powers, trusts,
duties and obligations, any and all such instruments in writing shall, on
request, be executed, acknowledged and delivered by the Issuer. If any separate
trustee or co-trustee, or a successor to either, shall die, become incapable of
acting or not be qualified to act, resign or be removed, all the estates,
properties, rights, powers, trusts, duties and obligations of such separate
trustee or co-trustee, so far as permitted by law, shall vest in and be
exercised by the Trustee until the appointment of a successor to such separate
trustee or co-trustee.

        Section 8.14. Qualifications. (a) Each successor to the Trustee and each
institutional co-trustee (if any) shall at all times be a bank or trust company,
which (i) is organized as a banking corporation or association and doing
business under the laws of the United States or any state thereof, (ii) is
authorized under such laws to exercise corporate trust powers, (iii) is subject
to supervision or examination by federal or state authority, (iv) has combined
capital and surplus (as set forth in its most recent published report of
condition) of at least $50,000,000, and (v) shall not have become incapable of
acting or have been adjudged a bankrupt or an insolvent nor have had a receiver
appointed for itself or for any of its property, nor have had a public officer
take charge or control of it or its property or affairs for the purpose of
rehabilitation, conservation or liquidation.

        (b) Should any successor to the Trustee or any institutional co-trustee
at any time cease to be eligible, pursuant to this Section 8.14, to act as
successor Trustee or co-trustee (as the case may be), it shall promptly notify
the Owners of all Outstanding Bonds, the Issuer, the Borrower, any Letter of
Credit Issuer, the Remarketing Agent and the Tender Agent of such fact; such
notice shall be sent by certified mail, postage prepaid, to the Bond Owners. Any
such notice shall set forth all the relevant facts known to the Trustee or such
co-trustee (as the case may be).

                             SUPPLEMENTAL INDENTURES

        Section 9.1. Supplemental Indentures Not Requiring Consent of Bond
Owners. Subject to the terms and provisions of Sections 9.3 and 9.4 of this
Indenture, the Issuer and the Trustee may, without the consent of, or notice to,
any of the Bond Owners, enter into an indenture or indentures supplemental to
this Indenture, not inconsistent with the terms and provisions hereof, for any
one or more of the following purposes: (i) to cure any ambiguity, formal defect
or omission in this Indenture; (ii) to grant to or confer upon the Trustee, for
the benefit of the Bond Owners, any additional rights, remedies, powers or
authorities that may lawfully be granted to or conferred upon the Bond Owners or
the Trustee; (iii) to subject to this Indenture additional revenues, properties
or collateral; (iv) to modify, amend or supplement this Indenture, or any
indenture supplemental hereto, in such manner as to permit the qualification
hereof and thereof under the Trust Indenture Act of 1939, as amended, or any
similar federal statute hereafter in effect, or to permit the qualification of
the Bonds for sale under the securities laws of any of the states of the United
States, and if the Issuer so determines, to add to this Indenture or any
indenture supplemental hereto such other terms, conditions and provisions as may
be permitted by the Trust Indenture Act of 1939, as amended, or any similar
federal statute; (v) to add to the covenants and agreements of the Issuer
contained in this Indenture other covenants and agreements thereafter to be
observed for the protection of the Bond Owners or to surrender or limit any
right, power or authority herein reserved to or conferred upon the Issuer; (vi)
to modify, amend or supplement this Indenture, or any indenture supplemental
hereto, in any manner, provided that such modification, amendment or supplement
does not take effect until the next succeeding Conversion Date or commencement
of a Term Rate Period; and (vii) to make any other change which does not have a
material adverse effect upon the interests of the Bond Owners.

        Section 9.2. Supplemental Indentures Requiring Consent of Bond Owners.
Exclusive of supplemental indentures covered by Section 9.1 hereof, this
Indenture may be amended or supplemented only as provided in this Section 9.2.
Subject to the terms and provisions contained in Sections 9.3 and 9.4 of this
Indenture, the Owners of more than fifty percent (50%) in aggregate principal
amount of the Bonds then Outstanding shall have the right, from time to time, to
approve the execution by the Issuer and the Trustee of such indenture or
indentures supplemental hereto as shall be deemed necessary and desirable by the
Issuer for the purposes of modifying, altering, amending, adding to or
rescinding, in any particular, any of the terms or provisions contained in this
Indenture or in any supplemental indenture. If at any time the Issuer shall
request the Trustee to enter into any such supplemental indenture for any of the
purposes of this Section, the Trustee shall, upon being satisfactorily
indemnified with respect to expenses, cause notice of the proposed execution of
such supplemental indenture to be mailed by certified mail to the Bond Owners.
Such notice shall briefly set forth the nature of the proposed supplemental
indenture and shall state that copies thereof are on file at the principal
corporate trust office of the Trustee for inspection by all Bond Owners. If,
within sixty (60) days, or such longer period as shall be prescribed by the
Issuer, following the mailing of such notice, the Owners of the requisite
percentage in aggregate principal amount of the Bonds Outstanding at the time of
the execution of any such supplemental indenture shall have consented to and
approved the execution thereof as herein provided, no Owner of any Bond shall
have any right to object to any of the terms and provisions contained therein,
or the operation thereof; or in any manner to question the propriety of the
execution thereof; or to enjoin or





                                       71
<PAGE>   77

restrain the Trustee or the Issuer (subject to Section 9.4) from executing the
same or from taking any action pursuant to the provisions thereof. Upon the
execution of any such supplemental indenture as in this Section and Section 9.4
permitted and provided, this Indenture shall be and be deemed to be modified and
amended in accordance therewith.

        Section 9.3. Limitation Upon Amendments and Supplements. Nothing
contained in Sections 9.1 and 9.2 hereof shall permit, or be construed as
permitting, without the consent and approval of the Owners of all of the Bonds
then Outstanding (i) an extension of the maturity of the principal of, or the
time for payment of any redemption premium or interest on, any Bond or a
reduction in the principal amount of any Bond, or the rate of interest or
redemption premium thereon, or a reduction in the amount of, or extension of the
time of any payment required by, any Bond; (ii) a privilege or priority of any
Bond over any other Bond (except as herein provided); (iii) a reduction in the
aggregate principal amount of the Bonds required for consent to such a
supplemental indenture; (iv) the deprivation of the Owner of any Bond then
Outstanding of the lien created by this Indenture; or (v) the amendment of this
Section 9.3. No amendment or supplement to this Indenture may be entered into
without the Trustee and the Issuer first receiving (a) a Favorable Opinion of
Bond Counsel; and (b) written evidence from each Rating Agency then rating the
Bonds (if the Bonds are then rated) to the effect that such Rating Agency has
reviewed the amendment or supplement, and that the effectiveness thereof will
not, by itself, result in a reduction or withdrawal of such Rating Agency's then
current rating on the Bonds.

        Section 9.4. Consent of Trustee, Letter of Credit Issuer, Borrower,
Remarketing Agent and Tender Agent Required. This Indenture may not be amended
without the consent of the Trustee and any Letter of Credit Issuer. The Trustee
shall not be required to give its consent to any amendment which shall increase
its duties, responsibilities, obligations or standards of care or decrease the
protections afforded by this Indenture. Anything herein to the contrary
notwithstanding, an amendment or supplemental indenture under this Article IX
shall not become effective unless and until the Borrower shall have consented in
writing to the execution and delivery thereof; provided, however, that the
consent of the Borrower shall not be required during any period that an event of
default exists under the Loan Agreement. The Trustee shall inform the Tender
Agent and the Remarketing Agent of any amendment or supplement to this Indenture
affecting the respective rights and obligations of the Tender Agent and the
Remarketing Agent, and such amendment or supplement shall not become effective
unless and until the Tender Agent or the Remarketing Agent, as the case may be,
shall have consented in writing to the provisions thereof which affect its
rights and obligations.

        Section 10.1. Amendments of Loan Agreement and Tax Certificate Not

                                       72
<PAGE>   78

for the benefit of the Bond Owners, any additional rights, remedies, powers or
authorities that lawfully may be granted to or conferred upon the Issuer or the
Trustee; (iii) to amend or modify the Loan Agreement or the Tax Certificate, or

the interest on the Bonds; (iv) to amend or modify the Loan Agreement in any
manner, provided that such amendment or modification shall not take effect until

from time to time, to consent to and approve any amendment or modification of
the Loan Agreement or the Tax Certificate as shall be deemed necessary and
desirable by the Trustee for the purpose of amending and modifying, in any
particular, any of the terms or provisions contained in the Loan Agreement or
the Tax Certificate. If at any time the Trustee shall be asked to enter into or
to consent to any such amendment or modification, the Trustee shall, upon being
satisfactorily indemnified with respect to expenses, cause notice of the
proposed execution of such modification or amendment to be mailed by certified
mail to the Bond Owners. Such notice shall briefly set forth the nature of the
proposed amendment or modification and shall state that copies thereof are on
file at the principal corporate trust office of the Trustee for inspection by
the Bond Owners. If, within sixty (60) days, or such longer period as shall be
prescribed by the Issuer, following the mailing of such notice, the Owners of
the requisite percentage in aggregate principal amount of the Bonds Outstanding
at the time of the execution of any such amendment or modification shall have
consented to and approved the execution thereof as herein provided, no Owner of
any Bond shall have any right to object to any of the terms and provisions
contained therein, or the operation thereof; or in any manner to question the
propriety of the execution thereof; or to enjoin or restrain the Trustee or the

pursuant to the provisions thereof.

        Section 10.3. Limitation Upon Amendment of Loan Agreement. Nothing
contained in Sections 10.1 and 10.2 of this Indenture shall permit, or be
construed as permitting, without the approval and consent of the Owners of all
of the Bonds then Outstanding, (i) the extension of the time for any payment
under the Loan Agreement or a reduction in the amount of any payment under the
Loan Agreement, or (ii) the payment to any person other than the Trustee and the
Tender Agent as provided herein of any amount (except amounts due under Sections
7.11, 8.5 and 9.3 of the Loan Agreement) due under the Loan Agreement. No
amendment of the Loan Agreement may be entered into without the Trustee and the
Issuer first receiving (a) a Favorable Opinion of Bond Counsel, and (b) written
evidence from each Rating Agency then rating the Bonds (if the Bonds are then
rated) to the effect that the appropriate Rating Agency has reviewed the
amendment, and that the effectiveness thereof will not, by itself, result in a
reduction or withdrawal of such Rating Agency's then current rating on the
Bonds. The Trustee shall not be required to give its consent to any amendment of
the Loan Agreement or the Tax Certificate which shall increase its duties,





                                       73
<PAGE>   79

responsibilities, obligations or standards of care or decrease the protections

approval, objection or other instrument required by this Indenture to be signed
and executed by a Bond Owner may be in any number of concurrent writings of
similar tenor, and may be signed or executed by such Bond Owner in person or by
such Bond Owner's agent appointed in writing. The fact and date of the execution
by any person of any such consent, request, direction, approval, objection or
other instrument, or of the writing appointing any such agent, may be proved in
any jurisdiction by the certificate of any officer who by law has the power to
take acknowledgments within such jurisdiction that the person signing such
writing acknowledged before him the execution thereof, or by an affidavit of any
witness to such execution or in any other manner satisfactory to the Trustee,
and if made in any such manner shall be sufficient for any of the purposes of
this Indenture, and shall be conclusive in favor of the Trustee with regard to
any action taken by it under such request or other instrument. The ownership of
Bonds shall be proved by the Registration Books.

        Section 11.2. Limitation of Rights. With the exception of rights herein

               Section 220(a), the Trustee shall not give notice of redemption
               of the Bonds unless and until the Trustee has received either
               Available Moneys or, with the prior written consent of the Credit

               any, accrued thereon to the date of redemption, and such notice
               shall be of no effect unless such moneys are so deposited. If the
               Trustee does not have Available Moneys on deposit hereunder
               sufficient and available to pay the redemption price of such
               Bonds, such redemption shall be cancelled.

Statement if required by the Securities Act and, if the Registrants do not
reasonably object, as reasonably requested by the Fund on behalf of the Holders.

          (d) Each Holder wishing to sell Registrable Securities pursuant to a

         post-effective amendment to the Shelf Registration Statement or prepare
         and, if required by applicable law, file a supplement to the related
         Prospectus or a supplement or amendment to any document incorporated

         Holder delivering such Notice and Questionnaire is named as a selling
         securityholder in the Shelf Registration Statement and the related
         Prospectus in such a manner as to permit such Holder to deliver such
         Prospectus to purchasers of the Registrable Securities in accordance
         with applicable law and, if the Registrants shall file a post-effective
         amendment to the Shelf Registration Statement, use their reasonable
         best efforts to cause such post-effective amendment to become effective
         under the Securities Act as promptly as is practicable, but in any
         event by the date (the "AMENDMENT EFFECTIVENESS DEADLINE DATE") 45 days
         after the date such post-effective amendment is required by this clause
         to be filed;

                  (ii) provide such Holder copies of any documents filed
         pursuant to Section 2(d)(i); and

                  (iii) notify such Holder as promptly as practicable after the
         effectiveness under the Securities Act of any post-effective amendment
         filed pursuant to Section 2(d)(i);

provided that if such Notice and Questionnaire is delivered during a Deferral
Period, the Registrants shall so inform the Holder delivering such Notice and
Questionnaire and shall take the actions set forth in clauses (i), (ii) and
(iii) above upon expiration of the Deferral Period in accordance with Section
3(i). The Registrants shall be under no obligation to name any Holder that is
not a Notice Holder as a selling securityholder in any Shelf Registration
Statement or related Prospectus.

          SECTION 3. Registration Procedures. In connection with the
registration obligations of the Registrants under Section 2 hereof, the
Registrants shall:

          (a) Before filing any Registration Statement or Prospectus or any
amendments or supplements thereto with the SEC, furnish to the Fund copies of
all such documents

<PAGE>   6
proposed to be filed and use their reasonable best efforts to reflect in each
such document when so filed with the SEC such comments as the Fund reasonably
shall propose and to which the Registrants do not reasonably object within two
Business Days of the delivery of such copies to the Fund.

          (b) Prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such
Registration Statement continuously effective from the Effectiveness Deadline
Date to the expiration of the Effectiveness Period; cause the related Prospectus
to be supplemented by any required prospectus supplement, and as so supplemented
to be filed pursuant to Rule 424 (or any similar provisions then in force) under
the Securities Act; use their reasonable best efforts to comply with the
provisions of the Securities Act applicable to it with respect to the
disposition of all securities covered by such Registration Statement until the
expiration of the Effectiveness Period in accordance with the intended methods
of disposition by the sellers thereof set forth in such Registration Statement
as so amended or such Prospectus as so supplemented.

          (c) As promptly as practicable, give notice to the Notice Holders and
the Fund (i) when any Prospectus, prospectus supplement, Registration Statement
or post-effective amendment to a Registration Statement has been filed with the
SEC and, with respect to a Registration Statement or any post-effective
amendment, when the same has become effective, (ii) of any request, following
the effectiveness of the Initial Shelf Registration Statement under the
Securities Act, by the SEC or any other federal or state governmental authority
for amendments or supplements to any Registration Statement or related
Prospectus or for additional information, (iii) of the issuance by the SEC or
any other federal or state governmental authority of any stop order suspending
the effectiveness of any Registration Statement or the initiation or threatening
of any proceedings for that purpose, (iv) of the receipt by the Registrants of
any notification with respect to the suspension of the qualification or
exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction or the initiation or threatening of any proceeding for such
purpose, (v) of the occurrence of a Material Event and (vi) of the determination
by the Registrants that a post-effective amendment to a Registration Statement
would be appropriate, which notice may, at the discretion of the Registrants (or
as required pursuant to Section 3(i)), state that it constitutes a Deferral
Notice, in which event the provisions of Section 3(i) shall apply.

          (d) Use their reasonable best efforts to obtain the withdrawal of any
order suspending the effectiveness of a Registration Statement or the lifting of
any suspension of the qualification (or exemption from qualification) of any of
the Registrable Securities for sale in any jurisdiction in which they have been
qualified for sale, in either case at the earliest possible moment

                                       6

          (e) If reasonably requested by the Fund or any Notice Holder, as
promptly as practicable incorporate in a prospectus supplement or post-effective
amendment to a Registration Statement such information as the Fund or such
Notice Holder shall, on the basis of an opinion of nationally-recognized counsel
experienced in such matters, determine to be required to be included therein by
applicable law and make any required filings of such prospectus supplement or
such post-effective amendment; provided that the Registrants shall not be
required to take any actions under this Section 3(e) that are not, in the
reasonable opinion of counsel for the Registrants, in compliance with applicable
law.

          (f) Upon their request, as promptly as practicable furnish to each
Notice Holder and the Fund, without charge, at least one conformed copy of any
Registration Statement and any amendment thereto, including exhibits.

          (g) Deliver to each Notice Holder in connection with any sale of
Registrable Securities pursuant to a Registration Statement, without charge, as
many copies of the Prospectus relating to such Registrable Securities (including
each preliminary prospectus) and any amendment or supplement thereto as such
Notice Holder may reasonably request; and the Registrants hereby consent to the
use of the Prospectus and each amendment or supplement thereto by each Notice
Holder in connection with any offering and sale of the Registrable Securities
covered by such Prospectus or any amendment or supplement thereto in the manner
set forth therein.

          (h) Prior to any public offering of the Registrable Securities,
register or qualify or cooperate with the Notice Holders in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as
any Notice Holder reasonably requests in writing (which request may be included
in the Notice and Questionnaire); keep each such registration or qualification
(or exemption therefrom) effective during the period that a Shelf Registration
Statement is required to be effective and do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of such
Registrable Securities in the manner set forth in the applicable Registration
Statement and the related Prospectus; provided that in no event shall the
Registrants be obligated to (i) qualify as a foreign corporation in any
jurisdiction in which it would not otherwise be so required to qualify but for
this Section 3(h) or (ii) file any general consent to service of process in any
jurisdiction where it is not as of the date hereof not so subject.

          (i) Upon (A) the issuance by the SEC of a stop order suspending the
effectiveness of the Shelf Registration Statement or the initiation of
proceedings with respect to the Shelf Registration Statement under Section 8(d)
or 8(e) of the Securities Act, (B) the occurrence of any event or the existence
of any fact (a "MATERIAL EVENT") as a result of which any Registration Statement
shall contain any untrue statement of a


                                       7
<PAGE>   8
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading, or any Prospectus
shall contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or (C) the occurrence or existence of any pending corporate
development or public filing with the SEC that, in the sole discretion of the
Registrants, makes it appropriate to suspend the availability of the Shelf
Registration Statement and the related Prospectus:

                  (i) in the case of clause (B) above, subject to the next
         sentence, as promptly as practicable prepare and file, if necessary
         pursuant to applicable law, a post-effective amendment to such
         Registration Statement or a supplement to the related Prospectus or any
         document incorporated therein by reference or file any other required
         document that would be incorporated by reference into such Registration
         Statement and Prospectus so that such Registration Statement does not
         contain any untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading (except for an untrue statement of a
         material fact or omission of a material fact made in reliance on and in
         conformity with written information furnished to the Registrants by or
         on behalf of Notice Holders specifically for use therein), and such
         Prospectus does not contain any untrue statement of a material fact or
         omit to state any material fact required to be stated therein or
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading (except for an
         untrue statement of a material fact or omission of a material fact made
         in reliance on and in conformity with written information furnished to
         the Registrants by or on behalf of Notice Holders specifically for use
         therein), as thereafter delivered to the purchasers of the Registrable
         Securities being sold thereunder, and, in the case of a post-effective
         amendment to a Registration Statement, subject to the next sentence,
         use their reasonable best efforts to cause it to become effective as
         promptly as is practicable, and

                  (ii) give notice to the Notice Holders that the availability
         of the Shelf Registration Statement is suspended (a "DEFERRAL NOTICE")
         and, upon receipt of any Deferral Notice, each Notice Holder shall not
         sell any Registrable Securities pursuant to the Registration Statement
         until such Notice Holder's receipt of copies of the supplemented or
         amended Prospectus provided for in clause (i) above, or until it is
         advised in writing by the Registrants that the Prospectus may be used,
         and has received copies of any additional or supplemental filings that
         are incorporated or deemed incorporated by reference in such
         Prospectus.

The Registrants will use their reasonable best efforts to ensure that the use of
the Prospectus may be resumed (x) in the case of clause (A) above, as promptly
as is


                                       8
<PAGE>   9
practicable, (y) in the case of clause (B) above, as soon as, in the sole
judgment of the Registrants, public disclosure of such Material Event would not
be prejudicial to or contrary to the interests of the Registrants or, if
necessary to avoid unreasonable burden or expense, as soon as practicable
thereafter and (z) in the case of clause (C) above, as soon as, in the sole
discretion of the Registrants, such suspension is no longer appropriate. The
Registrants shall be entitled to exercise their right under this Section 3(i) to
suspend the availability of the Shelf Registration Statement or any Prospectus
no more than one time in any three month period or two times in any twelve month
period, and the period during which the availability of the Registration
Statement and any Prospectus is suspended (the "DEFERRAL PERIOD") shall not
exceed thirty days; provided that in the case of a Material Event relating to
(I) an acquisition or a probable acquisition meeting the significance test of
Rule 3-05(b)(2)(iv) of Regulation S-X under the Securities Act, (II) a financing
or (III) a similar transaction, the Registrants may deliver to Notice Holders a
second certificate to the effect set forth above, which shall have the effect of
extending the Deferral Period by up to an additional 30 days, or such shorter
period of time as is specified in such second notice; provided that the
aggregate duration of any Deferral Periods shall not exceed 60 days in any three
month period or 90 days in any 12 month period.

          (j) Comply with all applicable rules and regulations of the SEC and
make generally available to their securityholders earning statements (which need
not be audited) satisfying the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder (or any similar rule promulgated under the Securities
Act) no later than 45 days after the end of any 12-month period (or 90 days
after the end of any 12-month period if such period is a fiscal year) commencing
on the first day of the first fiscal quarter of the Registrants commencing after
the effective date of a Registration Statement, which statements shall cover
said 12-month periods.

          (k) Cooperate with each Notice Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to a Registration Statement, which certificates shall not bear
any restrictive legends, and cause such Registrable Securities to be in such
denominations and registered in such names as such Notice Holder may request.

          (l) Provide a CUSIP number for all Registrable Securities not later
than the effective date of the Initial Shelf Registration Statement and provide
the transfer agent and registrar with printed certificates for the Registrable
Securities that are in a form eligible for deposit with the Depository Trust
Company.

          (m) Provide such information as is required for any filings required
to be made with the National Association of Securities Dealers, Inc.


                                       9
<PAGE>   10
          (n) Upon (i) the filing of the Initial Shelf Registration Statement
and (ii) the effectiveness of the Initial Shelf Registration Statement, announce
the same, in each case by release to Reuters Economic Services and Bloomberg
Business News.

          SECTION 4. Holder's Obligations. Each Holder agrees, by acquisition of
the Registrable Securities, that no Holder of Registrable Securities shall be
entitled to sell any of such Registrable Securities pursuant to a Registration
Statement or to receive a Prospectus relating thereto, unless such Holder has
furnished the Registrants with a Notice and Questionnaire as required pursuant
to Section 2(d) hereof (including the information required to be included in
such Notice and Questionnaire) and the information set forth in the next
sentence. Each Notice Holder shall promptly furnish to the Registrants all
information required to be disclosed in order to make the information previously
furnished to the Registrants by such Notice Holder not misleading and any other
information regarding such Notice Holder and the distribution of such
Registrable Securities as the Registrants may from time to time reasonably
request. Any sale of any Registrable Securities by any Holder shall constitute a
representation and warranty by such Holder that the information relating to such
Holder and its plan of distribution is as set forth in the Prospectus delivered
by such Holder in connection with such disposition, that such Prospectus does
not as of the time of such sale contain any untrue statement of a material fact
relating to or provided by such Holder or its plan of distribution and that such
Prospectus does not as of the time of such sale omit to state any material fact
relating to or provided by such Holder or its plan of distribution necessary to
make the statements in such Prospectus, in the light of the circumstances under
which they were made, not misleading.

         SECTION 5. Registration Expenses. The Registrants shall bear all fees
and expenses incurred in connection with the performance by the Registrants of
their obligations under Sections 2 and 3 whether or not any Registration
Statement becomes effective. Such fees and expenses shall include, without
limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses (x) with respect to filings required to be made with the
National Association of Securities Dealers, Inc. and (y) to comply with federal
and state securities or Blue Sky laws (including, without limitation, reasonable
fees and disbursements of the counsel specified in the next sentence in
connection with Blue Sky qualifications of the Registrable Securities under the
laws of such jurisdictions as the Notice Holders may designate pursuant to
Section 3(h)), (ii) printing expenses (including, without limitation, expenses
of printing certificates for Registrable Securities in a form eligible for
deposit with The Depository Trust Company, (iii) duplication expenses relating
to copies of any Registration Statement or Prospectus delivered to any Holders
hereunder, (iv) fees and disbursements of counsel for the Registrants in
connection with the Shelf Registration Statement, (v) reasonable fees and
disbursements of the registrar and transfer agent for the Series B Preferred
L.P. Units, the Parent REIT Preferred Securities or the Trust Preferred
Securities and (vi) Securities Act liability insurance obtained by the
Registrants in their sole discretion. In addition, the


                                       10
<PAGE>   11
Registrants shall bear or reimburse the Notice Holders for the reasonable fees
and disbursements of one firm of legal counsel for the Holders, which shall be a
nationally recognized law firm experienced in securities law matters designated
by the Fund. In addition, the Registrants shall pay the internal expenses of the
Registrants (including, without limitation, all salaries and expenses of
officers and employees performing legal or accounting duties), the expense of
any annual audit, the fees and expenses incurred in connection with the listing
of the Registrable Securities on any securities exchange on which similar
securities of the Registrants are then listed and the fees and expenses of any
person, including special experts, retained by the Registrants. Notwithstanding
the provisions of this Section 5, each seller of Registrable Securities shall be
responsible for any underwriting discounts and commissions related to the sale
of such seller's Registrable Securities and shall pay all registration expenses
to the extent the Registrants are prohibited by applicable Blue Sky laws from
paying for or on behalf of such seller of Registrable Securities.

          SECTION 6. Indemnity and Contribution. (a) The Registrants agree,
jointly and severally, to indemnify and hold harmless each Notice Holder and
each person, if any, who controls any Notice Holder within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred in connection with
defending or investigating any such action or claim) caused by any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement or Prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or caused by any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, except insofar as such losses,
claims, damages or liabilities are caused by any such untrue statement or
omission or alleged untrue statement or omission based upon information relating
to any Holder furnished to the Registrants in writing by such Holder expressly
for use therein; provided, however, that the foregoing indemnity agreement with
respect to any preliminary prospectus or Prospectus shall not inure to the
benefit of any Notice Holder from whom the person asserting any such losses,
claims, damages or liabilities purchased Registrable Securities, or any person
controlling such Notice Holder, if a copy of the Prospectus (as then amended or
supplemented if the Registrants shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Notice Holder
to such person, if required by law so to have been delivered, at or prior to the
written confirmation of the sale of the Registrable Securities to such person,
and if the Prospectus (as so amended or supplemented) would have cured the
defect giving rise to losses, claims, damages or liabilities, unless such
failure is the result of noncompliance by the Registrants with Section 3(b),
3(e) and 3(i).

          (b) Each Holder agrees severally, and not jointly, to indemnify and
hold harmless the Registrants, their respective directors, trustees and officers
and each person,


                                       11
<PAGE>   12
if any, who controls any Registrant within the meaning of either Section 15 of
the Securities Act or Section 20 of the Exchange Act, to the same extent as the
foregoing indemnity from the Registrants to such Holder, but only with reference
to information relating to such Holder furnished in writing by such Holder to
the Registrants expressly for use in such Registration Statement or Prospectus;
provided that with respect to any amount due to an indemnified person under this
paragraph (b), each Holder shall be liable only to the extent of the net
proceeds received by such Holder upon the sale of the Registrable Securities
pursuant to the Registration Statement giving rise to such indemnification
obligation.

          (c) In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to Section 6(a) or 6(b), such person (the "INDEMNIFIED PARTY")
shall promptly notify the person against whom such indemnity may be sought (the
"INDEMNIFYING PARTY") in writing. If an indemnifying party so elects within a
reasonable time after receipt of such notice, an indemnifying party, severally
or jointly with any other indemnifying parties receiving such notice, may assume
the defense of such proceeding with counsel chosen by it and reasonably
acceptable to the indemnified parties, provided that if (i) representation of
such indemnified party by the same counsel would present a conflict of interest
or (ii) the actual or potential parties (including impleaded parties) to, or
targets of, any such proceeding included both the indemnified party and the
indemnifying party and any such indemnified party reasonably determines that
there may be legal defenses available to such indemnified party which are
different from or in addition to those available to such indemnifying party,
then the indemnifying parties shall not be entitled to assume such defense. If
an indemnifying party is not entitled to assume the defense of such proceeding
as a result of the proviso to the preceding sentence, the indemnified party or
parties shall be entitled to conduct the defense of such indemnified party or
parties with counsel of its choice. If an indemnifying party assumes the defense
of such action, in accordance with and as permitted by the provisions of this
Section 6(c), such indemnifying parties shall not be liable for any fees and
expenses of counsel for the indemnified parties incurred thereafter in
connection with such action. In any such proceeding, any indemnified party shall
have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such indemnified party unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is understood that the indemnifying party shall not, in respect of the legal
expenses of any indemnified party in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the fees and expenses of
more than one separate firm (in addition to any local counsel) for all
indemnified parties, and that all such fees and expenses shall be reimbursed as
they are incurred. Such firm shall be designated in writing by, in the case of
parties indemnified


                                       12
<PAGE>   13
pursuant to Section 6(a), the Holders of a majority of the Series B Preferred
L.P. Units represented by the Registrable Securities that were sold under the
Registration Statement and gave rise to the indemnity claim pursuant to Section
6(a) and, in the case of parties indemnified pursuant to Section 6(b), the
General Partner. The indemnifying party shall not be liable for any settlement
of any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel as contemplated by the second and third sentences of this paragraph, the
indemnifying party agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement. Notwithstanding the immediately preceding sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, an indemnifying party shall
not be liable for any settlement of the nature contemplated by this Section 6(c)
effected without its consent if such indemnifying party (i) reimburses such
indemnified party in accordance with such request to the extent it considers
such request to be reasonable and (ii) provides written notice to the
indemnified party substantiating the unpaid balance as unreasonable, in each
case prior to the date of such settlement. No indemnifying party shall, without
the prior written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

          (d) To the extent that the indemnification provided for under Section
6(a) or 6(b) hereof is unavailable to an indemnified party or is insufficient in
respect of any losses, claims, damages or liabilities referred to therein, then
each indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party or parties on the other hand or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the indemnifying party or
parties on the one hand and of the indemnified party or parties on the other
hand in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Registrants shall be
deemed to be


                                       13
<PAGE>   14
equal to the total net proceeds from the initial placement with the Fund
pursuant to the Contribution Agreement (before deducting expenses) of the Series
B Preferred L.P. Units underlying the Registrable Securities to which such
losses, claims, damages or liabilities relate. The relative benefits received by
any Holder shall be deemed to be equal to the value of receiving Registrable
Securities that are registered under the Securities Act. The relative fault of
the Holders on the one hand and the Registrants on the other hand shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Holders or by the
Registrants and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The Holders'
respective obligations to contribute pursuant to this paragraph are several in
proportion to the respective number of Registrable Securities they have sold
pursuant to a Registration Statement giving rise to the loss, claim, damage or
liability, and not joint.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(d) were determined by pro rata
allocation or by any other method or allocation that does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified party
in connection with investigating or defending any such action or claim.
Notwithstanding this Section 6(d), an indemnifying party that is a Holder
selling Registrable Securities shall not be required to contribute any amount in
excess of the amount by which the total price at which the Registrable
Securities sold by such indemnifying party and distributed to the public were
offered to the public exceeds the amount of any damages that such indemnifying
party has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

          (e) The remedies provided for in this Section 6 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or equity, including those available under the
Contribution Agreement or otherwise.

          (f) The indemnity and contribution provisions contained in this
Section 6 shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Holder or any person controlling any Holder, or any Registrant, or any
Registrant's officers, trustees or directors or any person controlling any
Registrant and (iii) the sale of any Registrable Securities by any Holder.


                                       14
<PAGE>   15

          SECTION 7. Information Requirements. If at any time before the end of
the Effectiveness Period any Registrant is not subject to the reporting
requirements of the Exchange Act, the Registrants will cooperate with any Holder
of Registrable Securities and take such further reasonable action as any Holder
of Registrable Securities may reasonably request (including, without limitation,
making such reasonable representations as any such Holder may reasonably
request), all to the extent required from time to time to enable such Holder to
sell Registrable Securities without registration under the Securities Act within
the limitation of the exemptions provided by Rule 144 and Rule 144A under the
Securities Act. Nothing in this Section 7 shall be deemed to require any
Registrant to register any of its securities under the Exchange Act.

          SECTION 8. Miscellaneous.

          (a) No Conflicting Agreements. The Registrants are not, as of the date
hereof, nor shall they, on or after the date of this Agreement, enter into any
agreement with respect to their securities that conflicts with the rights
granted to the Holders in this Agreement. The Registrants represent and warrant
that the rights granted to the Holders hereunder do not in any way conflict with
the rights granted to the holders of the Registrants' securities under any other
agreements.

          (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the Registrants have obtained the written consent of
Holders of a majority of the then outstanding Registrable Securities (based on
the number of Series B Preferred L.P. Units underlying such Registrable
Securities). Notwithstanding the foregoing, a waiver or consent to depart from
the provisions hereof with respect to a matter that relates exclusively to the
rights of Holders whose securities are being sold pursuant to a Registration
Statement and that does not directly or indirectly affect the rights of other
Holders may be given by Holders of at least a majority of the Registrable
Securities being sold by such Holders pursuant to such Registration Statement;
provided that the provisions of this sentence may not be amended, modified, or
supplemented except in accordance with the provisions of the immediately
preceding sentence.

          (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, by telecopier, by
courier guaranteeing overnight delivery or by first-class mail, return receipt
requested, and shall be deemed given (i) when made, if made by hand delivery,
(ii) upon confirmation, if made by telecopier, (iii) one Business Day after
being deposited with such courier, if made by overnight courier or (iv) on the
date indicated on the notice of receipt, if made by first-class mail, to the
parties as follows:

comply with the provisions of the Exchange Act and the rules thereunder relating
